Description

Technical Field

[0001] The utility model belongs to the technical field of frame assembly equipment, and particularly refers to a double-station pressing equipment for installing a frame flat fork bushing. Background Art

[0002] The flat fork, also known as the rear flat fork or rear fork, etc., is a component of the rear suspension of a motorcycle or an electric vehicle, used to connect the rear wheel with parts such as the body, frame, and shock absorber, playing the roles of bearing the body pressure, fixing the rear wheel, and maintaining the body stability.

[0003] Usually, two groups of bearings are arranged at both ends of the flat fork, and the size specifications of the two groups of bearings are usually different. During the assembly process, the bearings are installed in the mounting holes at both ends of the flat fork by means of pressing. Traditional pressing equipment often has a relatively simple structure and a single function, and requires secondary pressing for the installation of bearings with different specifications at both ends of the flat fork, resulting in low processing efficiency.

[0031] The present utility model will be further described below with reference to the accompanying drawings in specific embodiments. See Figure 1 — Figure 5 :

[0032] A double - station pressing device for installing a frame flat fork bushing, comprising a frame 1. A longitudinally arranged main cylinder 10 is fixed at the top of the frame 1, and a pressing die head 11 is fixed at the end of the piston rod of the main cylinder 10;

[0033] A lifting bottom plate 2 is slidably arranged in the middle of the frame 1 through a transverse slide rail. A pressing plate 20 is arranged on the front side of the lifting bottom plate 2, and two sets of upper die sets 3 with different specifications are arranged on the pressing plate 20,

[0034] A die base fixing plate 4 is slidably arranged at the lower part of the frame 1 through a transverse slide rail.

A connecting plate 40 is fixed on one side of the die base fixing plate 4, and the top of the connecting plate 40 is fixedly connected to the bottom of the lifting bottom plate 2,

[0035] When the die base fixing plate 4 slides left and right, the lifting bottom plate 2 slides left and right synchronously with the die base fixing plate 4. When the die base fixing plate 4 slides to the right end, the top of the upper die set 3 corresponds to the bottom of the pressing die head 11. When it slides to the left end, the top of the other upper die set 3 corresponds to the bottom of the pressing die head 11.

[0036] During the assembly and use of the front fork, the end is placed vertically, the mounting hole for the upper mounting bearing of the flat fork 6 is placed horizontally, and it is placed on top of the lower die set in a buckled manner. The lifting bottom plate and the die holder fixing plate are synchronously slid through the transverse slide rail, so that the bottom of the press-fitting die head can correspond to one of the upper die sets. Driven by the main cylinder, the upper die set is pressed down to fit with the lower die set to achieve the press-fitting of the bearing.

[0037] When switching the size, the operator rotates the flat fork. Similarly, in the form of placing the mounting hole horizontally, another matching upper die set 3 and the lower die set are used for the press-fitting of the bearing, realizing the operation of a double-station on a single device, which greatly improves the production efficiency.

[0038] Preferably, the upper die set 3 includes a linear bearing 30 fixed on the press-fitting plate 20. A guide rod 31 is inserted into the linear bearing 30. The top of the guide rod 31 is fixed with a guide rod top cover 32 for abutting against the bottom of the press-fitting die head 11, and the bottom of the guide rod 31 is fixed with an upper press head 33.

[0039] In the upper die set 3, the linear bearing 30 is used for the up and down sliding of the guide rod 30. The guide rod top cover 32 can play a limiting role and prevent the bearing at the bottom from being overly squeezed.

[0041] The pin shaft 51 is used for the positioning of the mounting hole in the flat fork and to prevent shaking.

[0042] Preferably, a return spring is provided between the lower end face of the guide rod top cover 32 and the press-fitting plate 20.

[0043] During the actual press-fitting process, after the guide rod top cover 32 is pressed down by the press-fitting die head 11, the guide rod can be jacked up and reset by the return spring.

[0044] In addition, in order to prevent the guide rod from being overly ejected from the linear bearing by the return spring, a snap ring is provided on the side wall of the guide rod, and the upper end face of the snap ring abuts against the lower end face of the linear bearing.

[0045] Preferably, a longitudinal slide rail 21 is provided on the front side of the lifting bottom plate 2. The rear end of the press-fitting plate 20 slides up and down along the longitudinal slide rail 21. A longitudinal adjustment cylinder 22 for driving the press-fitting plate 20 to slide up and down along the longitudinal slide rail 21 is fixed on the top of the lifting bottom plate 2.

[0046] In the above structure, the press-fitting plate 20 can be moved up and down by the longitudinal adjustment cylinder 22, which is convenient for adjusting the appropriate press-fitting height.

[0047] Preferably, the master cylinder 10 is a vertically arranged pneumatic-hydraulic intensifying cylinder. A plurality of guide columns 12 penetrate through the top of the frame 1, and a guide column connecting plate 13 is fixed to the bottom of the plurality of guide columns 12. The top of the guide column connecting plate 13 is fixedly connected to the end of the piston rod of the master cylinder 10, and the press-fitting die head 11 is fixed to the bottom of the guide column connecting plate 13. By adopting the above method, the press-fitting die head can be more stable and steady during the downward pressing and assembling process, avoiding shaking.

[0048] Preferably, material boxes 41 are arranged on both sides of the die base fixing plate 4. And the two material boxes 41 are used to place bearings of different specifications, so as to facilitate the operator to pick up and install the parts.

[0049] Preferably, the frame 1 is in a "C" shape.

[0050] Working principle:

[0051] A double-station press-fitting device for installing a frame flat fork bushing provided by the present utility model uses the form of a single main shaft pressing down to press two groups of press-fitting modules with different specifications that slide horizontally along a transverse slide rail. The structural design is simple, the press-fitting is convenient, and the convenience of installing bearings of different sizes on the flat fork is greatly improved.
