Zhou Xiangding a graph crankshaft of 1(b) of 4 turning graph one, this clamping apparatus can machine structure of clamping apparatus of neck of 4 connecting rod only general of 4 abduct crankshaft the first, neck of 4 connecting rod, because machine the 2nd, in the fixed position outfit that axial and circumferential direction do not have when neck of 3 connecting rod, reason cannot be machined. Accept the restriction of structure of clamping apparatus system, this clamping apparatus can machine brace radius to be in only 57.

The crankshaft under 5mm, and balance piece width is under 150mm. To fighting the bent axle that graph 1(b) place shows, as a result of the first, 8 arms are not had deserve to weigh piece, without right fixed position side, with this clamping apparatus cannot be machined at all. This clamping apparatus regards fixed position as component with space block, fixed position precision is inferior, in machining a process radius dimension cannot get brace to assure effectively. When to occupy above, this clamping apparatus can machine a few kinds of crankshaft such as YZ495, YZ4102, GB495Q1, 485Q only, and need configures lathe of crankshaft of a S1-217 to machine crankshaft the 2nd, neck of 3 connecting rod: If pursue,the crankshaft that 1(b) place shows can use treatment of lathe of S1-130C all-purpose crankshaft only, and the company does not have redundant S1-130C equipment. 2 improve the condition of 4 abduct crankshaft that at present we develop design foundation: Brace radius is between 65 ～ of 50 ～ , diameter of main shaft neck is between 70 ～ 90mm, archives is wide (length of axial of neck of individual main shaft) in 30mm above, overall length is under 752mm, be aimed at the problem of afore-mentioned existence, we designed a fixture, make its can be machined already all neck of 4 connecting rod, can machine the 4 abduct crankshaft of all model again. Clamping apparatus structure is shown 3 times like the graph, this clamping apparatus basically is provided by clip body 1, gland 2, tile fragment 3, fixed position 6, chuck 7 wait for a spare parts to form. Clamping apparatus one aspect of the matter and box of machine tool main shaft join, another end is chuck structure. Bottom of clamping apparatus body designs those who make the same score, open 3 groove, among them a groove uses fixed position, additional two groove use fixed axial to locate 6. Specific treatment method adjusts box of crankshaft lathe main shaft by craft above all, make distance of the tile fragment on body of left, right clamping apparatus is equal to 4 abduct crankshaft the first, 5 (or 2, 4) the distance of main shaft collar, screw the nut on main shaft box is secured next, press undermentioned method to machine: The crankshaft that place of treatment plan 1(a) shows one, method of location of neck of 4 connecting rod and graph the structure of 2 base wood is identical, here no longer give uncecessary details; Graph 3 it is the crankshaft that place of treatment plan 1(a) shows 2, 3 connecting rod place recognizance compose sketch map suddenly. The axial fixed position of crankshaft relies on fixed position piece 5 will come true, the fixed position of circumferential direction relies on fixed position piece 4 will finish; Graph 4 it is the crankshaft that place of treatment plan 1(b) shows one, sketch map of structure of clamping apparatus of neck of 4 connecting rod. The axial fixed position of crankshaft relies on tile fragment flank to come true, the fixed position of circumferential direction relies on fixed position piece 4 will finish; 1.

Zhou Xiangding a graph crankshaft of 1(b) of 5 turning graph 2, structure of clamping apparatus of neck of 3 connecting rod pursues 6 application are prejudicial tile fragment adjusts brace radius figure 5 it is the crankshaft that place of treatment plan 1(b) shows 2, structure of clamping apparatus of neck of 5 connecting rod. The axial fixed position of crankshaft relies on fixed position piece 4 will come true, the fixed position of circumferential direction relies on fixed position piece 6 will finish. 3 notes design this to plant muti_function the following should notice when clamping apparatus body: Cover with tiles the dimension of an aperture should enough big, so that machine other when the crankshaft of neck of large main shaft, but through changing tile fragment comes true; The least file with neck of crankshaft main shaft is wide will do not have plan tile the width with gland, go in in order to make sure the crankshaft of a handsome date can be put; When machining the crankshaft with brace different radius, but through changing prejudicial tile fragment comes true: If graph 6(a) place is shown, the mix that we design by X4105B crankshaft is particular, diameter of working procedure of main shaft neck is Ø81.

5mm, brace radius 60mm, the circle outside tile fragment and inside aperture is homocentric. If machine crankshaft of the 4100Q inside the cloud (diameter of working procedure of main shaft neck is Ø76.

5mm, music abduct radius 52.

When 5mm) , can make inside aperture Ø76.

The circle outside 5mm and tile fragment is prejudicial 7.

5mm(shows) like graph 6(b) place, such brace radius are adjusted for 52.

5mm; The dimension of the oldest structure that presses 4 abduct crankshaft designs lumen of clamping apparatus body, can machine the 4 abduct crankshaft of all model in order to ensure. This clamping apparatus can machine 4 conclusion the 4 abduct crankshaft of all firm model, enlarged equipment scope of application, solved the problem with insufficient facilities. The structure is simple, make convenient, cost inferior. Change when the crankshaft of different type, need to change only the small part such as tile fragment, fixed position piece, adjust convenient, quick, the successful go into operation that is a product laid technical foundation.
