The content of the invention
For raising pedal power assistant spring efficiency of assembling and assembly qualified rate, reduction labor strength, raising processing safety, the present invention proposes a kind of fixture being used for during car clutch pedal power assistant spring press-fits.
Therefore, the technical scheme is that：Pedal spring pressing clamp, including chuck body, it is characterised in that：The chuck body includes base, is respectively provided with base and spacing position-limit mechanism and the hold-down mechanism for being compressed to power assistant spring modular assembly are carried out to pedal support modular assembly；The position-limit mechanism includes the first alignment pin and the second alignment pin and the first pressing plate and the second pressing plate, the hold-down mechanism is correspondingly arranged in front of position-limit mechanism, hold-down mechanism includes a cylinder set straight up, pressure head is fixedly connected with the piston rod of cylinder, pressure head one end is provided with neck corresponding with guide rod in power assistant spring modular assembly, pressure head is connected to the top of guide rod when using, limiting plate is provided with the end cap of cylinder.
It is for a kind of improve of above-mentioned technical proposal：To improve press-fit effect, the cylinder is obliquely installed, make cylinder piston rod and power assistant spring modular assembly axle center be generally aligned in the same plane in, it is ensured that pressure head is fitted completely with power assistant spring upper surface when press-fiting.
Application method：
In use, first quickly position pedal support modular assembly by the first alignment pin, the second alignment pin, and being compressed by the first pressing plate and the second pressing plate makes it be fixed on fixture；Then the power assistant spring modular assembly being pre-assembled is supported in the support power assistant spring mounting pin in pedal support modular assembly by the mounting seat of its lower end, and the pressure head in hold-down mechanism is connected to the top of guide rod in power assistant spring modular assembly；Start cylinder, pressure head is moved downward along guide rod, power assistant spring is compressed, the stop motion when ram movement is to limiting plate, power assistant spring is compressed to limiting condition, now, the pedal arm power assistant spring mounting pin in pedal swinging arm modular assembly is loaded in the mounting groove on guide rod, linked up pedal support modular assembly, power assistant spring modular assembly, pedal swinging arm modular assembly finally by rotating shaft and self-locking nut；After being connected, cylinder is closed, pressure head is moved upwards along guide rod, power assistant spring diastole return, clutch pedal assembly assembling is finished.
Beneficial effect：
The present invention by setting position-limit mechanism and hold-down mechanism respectively, first pedal support modular assembly is carried out in assembling process spacing, power assistant spring modular assembly is compressed again, complete pedal spring to press-fit, greatly reduce labor strength, improve spring efficiency of assembling, avoid spring in installation process and jump out the accident of causing casualties, processing safety is improved, precision is press-fited while ensure that, assembly qualified rate is improved.The clamp structure is simple, make easy, and debugging cycle is short, cost is low, is conducive to improving the performance of enterprises, can promote the use of.

Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 1, Figure 2, Figure 3, Figure 4, a kind of pedal spring pressing clamp, including chuck body, the chuck body includes base 11, is respectively provided with spacing position-limit mechanism and the hold-down mechanism for being compressed to power assistant spring modular assembly 2 are carried out to pedal support modular assembly 1 on the pedestal 11；The position-limit mechanism includes the first alignment pin 12 and the second alignment pin 13 and the first pressing plate 14 and the second pressing plate 15, the hold-down mechanism is correspondingly arranged in front of position-limit mechanism, hold-down mechanism includes a cylinder 16 set straight up, pressure head 17 is fixedly connected with the piston rod of cylinder 16, neck corresponding with the gabarit of guide rod 6 in power assistant spring modular assembly 2 is provided with the right-hand member of pressure head 17, pressure head is connected to the top of guide rod when using, limiting plate 18 is provided with the end cap of cylinder 16.
