Description

Technical Field

[0001] The invention belongs to the technical field of cam system assembly, in particular to a cam system assembly tool. Background Art

[0002] like Figure 1 As shown, the cam system mainly consists of three parts: a slider seat 1, a cam slider 2, and a balancing compression spring 3. The slider seat and the cam slider are slidably matched, and the balancing compression spring is limited on the slider seat, which acts as a buffer for the cam slider. To prevent the cam slider from detaching from the slider seat, the cam slider is provided with an elastic limit block 4, which cooperates with the slider seat to limit the displacement distance of the cam slider. During the press-fit assembly, the slider seat is held with the compression spring limit hole on the slider seat facing upward, and the balancing compression spring is vertically inserted. After the balancing compression spring is limited, the cam slider is vertically press-fitted. During the press-fit process, the elastic limit block on the cam slider interferes with the balancing compression spring and the slider seat in turn, resulting in the slider seat and cam slider being unable to connect. Finally, the slider seat 1, cam slider 2, and balancing compression spring 3 are press-fitted into a whole and then installed on the pedal arm of the commercial vehicle automatic pedal assembly for use. Due to the small size of the slider seat and cam slider, manual installation is difficult and inefficient. Summary of the Invention

[0005] The above technical solution is further defined as follows: the structure of the base includes a bottom plate, a support seat is provided on the back of the bottom plate, the bottom plate is arranged in an inclined shape through the support seat, and a column protrudes outward from the support surface of the bottom plate.

[0006] As a further improvement to the above technical solution, a fixing hole is provided on the support seat.

[0007] The above technical solution is further limited in that the positioning member and the guide member are both formed by bending steel plates, the positioning member is fixedly connected to the column, a space is reserved between the bottom of the positioning member and the base plate, the guide member is fixed to the base plate, and the positioning member on the positioning member and the guide member on the guide member are arranged relative to each other.

[0008] The above technical solution is further improved in that a handle is provided on the base.

[0009] The above technical solution is further limited in that the slope of the inclined surface on the base is 15 to 25 degrees.

[0010] Beneficial effects: The present invention changes the assembly entry angle between the slider seat, the balancing compression spring and the cam slider through the inclined surface on the base, so that the assembly operation can be completed quickly, the work efficiency is improved, and it is beneficial to reduce production costs; the present invention has a simple overall structure, low production cost, light weight, and is easy for operators to use.

[0016] like Figure 2 As shown, a cam system assembly tool includes a base 5, and a positioning member 6 and a guide member 7 are provided on the inclined surface of the base. During assembly, the positioning member on the base is used to position the slider seat and the balancing spring assembly. The inclined surface on the base is used to adjust the assembly cut-in angle between the slider seat, the balancing spring and the cam slider. The guide member is used to guide the elastic limit block on the cam slider to the position where it fits with the slider seat.

[0017] like Figure 2 As shown, the structure of the base 5 includes a bottom plate 501, a support base 502 is provided on the back of the bottom plate, the bottom plate is arranged in an inclined shape through the support base, and a column 503 protrudes outward on the support surface of the bottom plate; this structure is simple, low in production cost and light in weight;

[0018] like Figure 2 As shown, the support base is provided with a fixing hole 504, and the support base is fixedly connected to the workbench through the bolts in the fixing hole to prevent the support base from shifting during assembly;

[0019] like Figure 2As shown, the positioning member 6 and the guide member 7 are both formed by bending steel plates. The positioning member is fixedly connected to the column. A space is reserved between the bottom of the positioning member and the base plate. The reserved space is to prevent the elastic limit block from interfering with the base plate during the press-fitting process. The guide member is fixed to the base plate, and the positioning member on the positioning member and the guide member on the guide member are arranged opposite to each other. This structure is simple, low in production cost, and light in weight.

[0020] like Figure 2 As shown, the base is provided with a handle 8, which is convenient for taking the tool;

[0021] like Figure 2 As shown, the slope of the inclined surface on the base is 15 to 25 degrees, which saves effort during press-fitting and facilitates workers to work quickly.

[0022] like Figure 3 As shown, the slider seat is placed in the positioning member, the balance spring is limited on the slider seat, the slider seat and the balance spring are inclined, and then the elastic limit block on the cam slider is inserted into the guide member; before the elastic limit block is inserted, the inclined surface of the elastic limit block contacts the outer side surface of the balance compression spring during the downward movement of the elastic limit block, effectively avoiding the end of the balance compression spring, so that the elastic limit block can move downward smoothly; when the elastic limit block enters the guide member, the inclined surface of the elastic limit block contacts the slider seat, and at the same time, the elastic limit block is deformed to flip outward (such as Figure 4 As shown), the deformed elastic limit block continues to move downward in the guide member, and after being separated from the slider seat, the elastic limit block returns to its original position by its own elastic force, and the elastic limit block cooperates with the slider seat in the sliding direction of the cam slider (as shown Figure 5 shown).
