As people's living standards improve, people's consumption of cars is also increasing, and the market for automotive parts is becoming larger and larger. In recent years, automotive parts manufacturers have also been developing rapidly, and the tilting rocker arm is an important part of the car's cab.

[0003] The most complex operation in the preparation of the hydraulic tilting rocker arm for the cab is the welding operation between the rocker arm shaft and the sleeve. In order to ensure the welding quality, the edge of the rocker arm shaft weld will be milled with a chamfer. This is called beveling. In order to ensure the weld is strong, when milling the beveling, it is necessary to mill a beveling of a specific size and angle according to the structure of the sleeve to be welded.

[0004] When operating the rocker arm, it is necessary to use tooling to fix it. The existing tooling for fixing the rocker arm is relatively complicated, which affects production efficiency. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a universal tooling for miniature cab rocker arms, which overcomes the deficiencies of existing technologies and effectively solves the problem that the existing tooling for fixing the rocker arm is relatively complicated and affects production efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A universal tooling for a miniature cab rocker arm includes a base plate. Support plates are symmetrically fixed on both sides of the top of the base plate, and support blocks are fixed at equal intervals on one side of the top of the base plate. A first positioning block and a second positioning block are equally distributed between the support blocks and the support plates, and the first positioning block and the second positioning block are staggered. A third positioning block and a fourth positioning block are equally distributed on the other side of the top of the base plate.

[0008] By placing the rocker arm on top of two support plates and positioning one end of the rocker arm's pivot in the groove on top of the support block, and by placing the rocker arm's shaft tightly against the first and third positioning blocks or the second and fourth positioning blocks respectively, the protrusion of the rocker arm's shaft rests on top of the first and third positioning blocks or the second and fourth positioning blocks, and the protrusion abuts against the first and second positioning rods, the rocker arm is limited and fixed.

[0009] Preferably, the top of the base plate has through holes that are evenly distributed, and the through holes are located between the two support plates.

[0010] The through holes facilitate the positioning and connection of the base plate.

[0011] Preferably, the outer wall of one side of the support plate has symmetrically distributed insertion holes.

[0012] The provided holes facilitate the hoisting of the support plate.

[0013] Preferably, each of the support blocks has an arc-shaped groove on its top, and the arc-shaped groove is adapted to the rotating shaft at one end of the rocker arm.

[0014] One end of the rocker arm is pivoted onto the top of the support block.

[0015] Preferably, the outer walls of the first positioning block and the second positioning block opposite to each other are connected to second positioning rods, and the outer walls of the third positioning block and the fourth positioning block opposite to each other are connected to first positioning rods.

[0016] The second positioning rod abuts against the shaft at one end of the rocker arm, and the first positioning rod abuts against the shaft at the other end of the rocker arm.

[0017] Preferably, slots are provided on one outer wall of the first positioning block, the second positioning block, the third positioning block and the fourth positioning block, and the first positioning rod and the second positioning rod are inserted into the slots.

[0018] The first positioning rod and the second positioning rod are inserted into the slot, so that the first positioning rod is inserted and fixed to the third positioning block and the fourth positioning block, and the second positioning rod is inserted and fixed to the first positioning block and the second positioning block.

[0019] The beneficial effects of this utility model are as follows:

[0020] By placing the rocker arm on top of two support plates and positioning one end of the rocker arm's pivot in a groove on top of the support block, and by tightly abutting the rocker arm's shaft against the first and third positioning blocks or the second and fourth positioning blocks, the protrusion of the rocker arm's shaft rests on top of the first and third positioning blocks or the second and fourth positioning blocks, and abuts against the first and second positioning rods, thus limiting and fixing the rocker arm, the problem of the complex steps and reduced production efficiency of fixing the rocker arm using existing tooling in the prior art is effectively solved.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Example:

[0026] Reference Figure 1-2 A universal tooling for a miniature cab rocker arm includes a base plate 1. Support plates 2 are symmetrically fixed on both sides of the top of the base plate 1. Support blocks 3 are fixed at equal intervals on one side of the top of the base plate 1. First positioning blocks 4 and second positioning blocks 5 are arranged at equal intervals between the support blocks 3 and the support plates 2. The first positioning blocks 4 and second positioning blocks 5 are staggered. Third positioning blocks 6 and fourth positioning blocks 7 are fixed at equal intervals on the other side of the top of the base plate 1.
