Abstract
Description
Technical Field
[0001] The utility model relates to the field of general industrial equipment, in particular to a fast pinning machine. Background Art
[0002] Pinning machines are commonly used in heavy industry assembly equipment and are widely used in specific operations such as boom pinning and track pinning. However, pinning machines in the prior art generally have certain disadvantages, that is, their application range is not wide.
[0003] Specifically, different models of equipment typically require customized pinning machines. From the frame to the tooling to the pressing equipment, each unit often requires individual molds and custom processing. This type of equipment lacks adjustment capabilities, meaning each model requires a custom pinning machine. This, combined with its limited application scenarios, significantly increases production costs. Non-customized pinning machines, on the other hand, are a complex process for aligning the pin shaft and pin hole, requiring the use of lifting equipment, fixtures, and repeated fine-tuning using hammering and other methods. Furthermore, because the fit between the pin shaft and the pin hole is generally a transitional fit, these machines can still be scrapped. Utility Model Content
[0004] The purpose of the utility model is to overcome the shortcomings of the existing technology and provide a fast pinning machine with fast pin shaft and pin hole alignment, flexible replacement of fixtures, simple structure and low scrap rate.
[0005] The equipment includes a frame, which is the assembly base of the equipment;
[0006] A locking unit and a pressing pin unit are respectively provided on the frame;
[0007] The locking unit includes an assembly base A, on which a plurality of tool holes are provided; a locking element A and a locking element B are provided opposite to each other in front of the assembly base A, and a pin identification hole is also provided in the center of the assembly base A;
[0008] The pinning unit includes an assembly base B, on which a pinning hydraulic cylinder is fixedly arranged in the center, a push plate is provided at the piston end of the pinning hydraulic cylinder, a plurality of tool setting shafts are fixed on the push plate, and the tail ends of the tool setting shafts are passed through the assembly base B, and the positions of the tool setting shafts and the tool setting holes correspond to each other;
[0009] A pin shaft tooling assembly base is fixedly arranged in front of the push plate.
[0010] The effect achieved by this is that the pinning hydraulic cylinder is actuated to push the assembly substrate B toward the assembly substrate A. When the lock parts A and B are not clamped with fixtures, the tool setting is completed once and the pinning hydraulic cylinder is retracted.
[0011] The pin fixture is assembled on the front of the base, and the pin is assembled inside the customized fixture. The hydraulic cylinder is pushed forward to complete the secondary tool setting.
[0012] Locking parts A and B clamp the pin to be pressed so that its pin hole fully corresponds to the pin shaft recognition hole; push the hydraulic cylinder to complete the pinning.
[0013] The beneficial effects of the present invention are as follows: the present invention ensures that the equipment runs without deviation by performing one-time tool setting between the tool hole and the tool shaft, and eliminates the pinning deviation by performing a secondary tool setting on the assembly pin shaft, and completes the pinning on this basis, thereby achieving the effect of reducing the scrap rate; on this basis, the above-mentioned adjustment method is different from the drawbacks of repeated adjustment of the non-standard parts pinning machine in the prior art, and improves the tool setting speed; and based on the above, the double tooling base configured in the present equipment solves the problem of single application function of the pinning machine in the prior art, and has a wider scope of application.
