Description

The mach self-centering fixture of irregular part

Technical field

The utility model relates to the mach self-centering fixture of a kind of irregular part.

Background technology

During traditional irregular part machined, generally or pressing plate fixing by strong point support fixedly reaches processing request, but for the part that piece surface need to be processed or the resetting clamping is had relatively high expectations, above-mentioned two kinds of clamping fixed forms are not very desirable just, cause piece surface not process at one time or resetting bad, each part will be adjusted repeatedly in the process, clamping, wasted a large amount of time, reduced working (machining) efficiency, and also unstable when adopting above-mentioned two kinds of installation way processing parts, part is loosening escaping easily, causes part to scrap.Although the clamping problem that adopts hydraulically operated fixture to solve irregular part is also arranged, and the hydraulically operated fixture cost is higher, at least tens0000, at most hundreds of thousands, and complex structure has improved production cost.

Summary of the invention

Technical problem to be solved in the utility model provides the mach self-centering fixture of a kind of irregular part, utilize these anchor clamps can conveniently implement the mach clamping of irregular part, guaranteed carrying out smoothly of processing operation, avoided scrapping of part, improve working (machining) efficiency, reduced production cost.

For solving the problems of the technologies described above, the mach self-centering fixture of the utility model irregular part comprises base, screw rod, handle, fixture block before the V-arrangement, fixture block behind the V-arrangement, four Universal support nails and two guide rails, described two guide rail parallel intervals are located on the described base, the V-arrangement face of fixture block arranges that in opposite directions also both sides have T-slot behind the front fixture block of described V-arrangement and the V-arrangement, fixture block is provided with the forward screw between two parties before the described V-arrangement, fixture block is provided with reverse screw between two parties behind the described V-arrangement, fixture block is located on described two guide rails and along guide rail by the T-slot of both sides and is moved behind the front fixture block of described V-arrangement and the V-arrangement, described screw rod is in the reverse screw of fixture block behind bidirectional helical and the forward screw of twisting respectively fixture block before described V-arrangement and the V-arrangement, described handle is fixed at described screw rod one end, and described four Universal supports nail is located at respectively before the described V-arrangement V-arrangement face of fixture block behind the fixture block and V-arrangement.

Further, above-mentioned handle adopts the plum blossom handle.

Further, the above-mentioned screw rod other end is provided with inner hexagonal hole.

Because the mach self-centering fixture of the utility model irregular part has adopted technique scheme, be that these anchor clamps comprise base, screw rod, handle, fixture block before the V-arrangement, fixture block behind the V-arrangement, four Universal support nails and two guide rails, two guide rail parallel intervals are located on the base, the V-arrangement face of fixture block arranges that in opposite directions also both sides have T-slot behind the front fixture block of V-arrangement and the V-arrangement, fixture block is provided with the forward screw between two parties before the V-arrangement, fixture block is provided with reverse screw between two parties behind the V-arrangement, fixture block is located on two guide rails and along guide rail by the T-slot of both sides and is moved behind the front fixture block of V-arrangement and the V-arrangement, screw rod is in the reverse screw of fixture block behind bidirectional helical and the forward screw of twisting respectively fixture block before V-arrangement and the V-arrangement, handle is fixed at screw rod one end, and four Universal supports nail is located at respectively before the V-arrangement V-arrangement face of fixture block behind the fixture block and V-arrangement.These anchor clamps can conveniently be implemented the mach clamping of irregular part, have guaranteed carrying out smoothly of processing operation, have avoided scrapping of part, have improved working (machining) efficiency, have reduced production cost.

Description of drawings

The utility model is described in further detail below in conjunction with drawings and embodiments:

Fig. 1 is the structural representation of the mach self-centering fixture of the utility model irregular part.

The specific embodiment

As shown in Figure 1, the mach self-centering fixture of the utility model irregular part comprises base 1, screw rod 6, handle 5, fixture block 2 before the V-arrangement, fixture block 7 behind the V-arrangement, 3 and two guide rails 4 of four Universal support nails, described two guide rail 4 parallel interval are located on the described base 1, the V-arrangement face of fixture block 7 arranges that in opposite directions also both sides have T-slot behind the front fixture block 2 of described V-arrangement and the V-arrangement, fixture block 2 is provided with the forward screw between two parties before the described V-arrangement, fixture block 7 is provided with reverse screw between two parties behind the described V-arrangement, fixture block 7 is located on described two guide rails 4 and along guide rail 4 by the T-slot of both sides and is moved behind the front fixture block 2 of described V-arrangement and the V-arrangement, described screw rod 6 is in the reverse screw of fixture block 7 behind bidirectional helical and the forward screw of twisting respectively fixture block 2 before described V-arrangement and the V-arrangement, described handle 5 is fixed at described screw rod 6 one ends, and described four Universal supports nail 3 is located at respectively before the described V-arrangement V-arrangement face of fixture block 7 behind the fixture block 2 and V-arrangement.

Further, for ease of turning of screw rod 6, above-mentioned handle 5 adopts the plum blossom handle.

Further, above-mentioned screw rod 6 other ends are provided with inner hexagonal hole.When processing thin-walled part, can adopt torque spanner to turn screw rod by inner hexagonal hole, adjust the chucking power of part, avoid the clamping distortion of part, to guarantee the crudy of part.

When irregular part machined operation, part is placed before the V-arrangement behind the fixture block and V-arrangement between the fixture block, turn screw rod by handle, fixture block is mobile in opposite directions along two guide rails after making the front fixture block of V-arrangement and V-arrangement, until the Universal support nail of fixture block V-arrangement face clamps part behind the front fixture block of V-arrangement and the V-arrangement, be convenient to the processing operation of part by the chucking power one that turns screw rod capable of regulating part; The Universal support nail can by the screw thread setting, can be made corresponding clamping end face according to part shape, to guarantee the reliability of part clamping.

This clamp structure is simple, and is easy to make, compares hydraulically operated fixture, and cost of manufacture is much lower, and parts fixation is convenient, has the repeated clamping Self-centering Action, has improved working (machining) efficiency, has reduced production cost.
