For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0034] Figure 1 This is a top view of the processing device for the gearbox housing in this invention; Figure 2 This is a perspective view of the processing device for the gearbox housing in this invention; Figure 3 This is a structural schematic diagram of the positioning component in this invention. Please refer to [link / reference]. Figures 1 to 3 As shown, a preferred embodiment is illustrated, which illustrates a processing device for a gearbox housing. The device is characterized by including a base plate 1, a positioning plate 2, positioning pins 3, and positioning mechanisms 4. The positioning plate 2 is provided at the upper middle part of the base plate 1. The positioning plate 2 has a plurality of mounting holes 5. At least two positioning pins 3 are vertically installed in two of the mounting holes 5 for horizontally limiting the gearbox housing. Two positioning mechanisms 4 are movably provided at both ends of the base plate 1.

[0035] The positioning mechanism 4 is used to vertically limit the gearbox housing and can exert downward pressure on the gearbox housing. In this embodiment, see... Figure 1 As shown, the mounting holes 5 on the mounting plate are arranged in a rectangular pattern. There are at least two positioning pins 3, which can be installed in any one of the mounting holes 5. They are used to cooperate with the positioning holes at the lower end of the gearbox housing to achieve horizontal limiting of the gearbox housing and prevent the gearbox housing from moving horizontally.

[0036] The horizontal position and height of the positioning mechanism 4 are adjustable to fit the positioning holes on the side wall of the gearbox. The positioning mechanism 4 can extend into the positioning holes on the side wall of the gearbox to achieve vertical positioning of the gearbox and prevent vertical displacement of the gearbox.

[0037] Furthermore, as a preferred embodiment, it also includes lifting lugs 6, with a plurality of lifting lugs 6 provided on the outer wall of the base plate 1. The lifting lugs 6 can be used with external hoisting equipment to facilitate the hoisting of the processing device onto the machine tool, and then the processing device is fixed on the machine tool by installing positioning bolts in the connecting holes 7 at the four corners of the base plate 1.

[0038] Furthermore, as a preferred embodiment, each positioning mechanism 4 includes:

[0039] Push plate 401 is disposed on the upper surface of base plate 1;

[0040] Cylinder 402 is located on one side of push plate 401 and is used to drive push plate 401 to move horizontally.

[0041] Guide block 403, the upper end of push plate 401 is provided with guide block 403;

[0042] A positioning component 404 is slidably mounted on a guide block 403. A cylinder 402 can push a push plate 401 to move on the base plate 1. The width of the push plate 401 is greater than the width of the guide block 403, so that the push plate 401 initially abuts against the bottom of the side wall of the gearbox housing, achieving preliminary fixation of the gearbox housing's position. Then, the positioning component 404 can be slid as needed to adjust its position, facilitating the positioning screw 413 on the positioning component 404 to enter the positioning hole on the side wall of the gearbox housing. The guide block 403 is welded and fixed to the upper end of the push plate 401.

[0043] Furthermore, as a preferred embodiment, it also includes a slider 405, a connecting rod 406, and a limiting plate 407. A guide groove is provided on the guide block 403, and the slider 405 is slidably disposed within the guide groove. The upper end of the slider 405 is provided with the connecting rod 406, and the upper end of the connecting rod 406 is provided with the limiting plate 407, which is located on the upper surface of the guide block 403. See also... Figure 2 As shown, the slider 405 is disposed in the guide groove and can slide in the guide groove, thereby driving the limiting plate 407 to slide. The limiting plate 407 is arranged in a "П" shape, and the inner walls on both sides of the limiting plate 407 abut against the outer walls on both sides of the guide block 403 to ensure the stability of the limiting plate 407.

[0044] Furthermore, as a preferred embodiment, the upper surface of the guide block 403 is provided with a plurality of first threaded holes 408, and the limiting plate 407 is provided with a through hole 409. A bolt 410 is provided in the through hole 409, and the lower end of the bolt 410 can extend into one of the first threaded holes 408. Through the mutual cooperation of the first threaded holes 408, the through hole 409 and the bolt 410, the position of the limiting plate 407 can be fixed, thereby fixing the position of the positioning mechanism 4.

[0045] Furthermore, as a preferred embodiment, the positioning assembly 404 includes an electric cylinder 411, a mounting block 412, a positioning screw 413, and a handle 414. The electric cylinder 411 is located at the upper end of the limiting plate 407. The upper end of the electric cylinder 411 is provided with the mounting block 412, which has a second threaded hole. The positioning screw 413 is located within the second threaded hole. One end of the positioning screw 413 is provided with the handle 414, and the other end of the positioning screw 413 can extend into a positioning hole on the side wall of the gearbox housing. In this embodiment, the electric cylinder 411 can drive the mounting block 412 to move up and down, facilitating the adjustment of the height of the positioning screw 413 to adapt to the height of the positioning hole on the side wall of the gearbox housing. The positioning screw 413 can rotate and advance within the second threaded hole to facilitate its entry into the positioning hole on the side wall of the gearbox housing. After the positioning screw 413 enters the positioning hole on the side wall of the gearbox, the electric cylinder 411 drives the positioning screw 413 to move downward and press down on the gearbox, making the position of the gearbox more stable after it is fixed and preventing the gearbox from shaking.

[0046] Furthermore, as a preferred embodiment, it also includes a support block 415. The support block 415 is integrally provided on the side of the mounting block 412 near the gearbox housing. The support block 415 has a third threaded hole directly opposite the second threaded hole. The other end of the positioning screw 413 passes through the second threaded hole and the third threaded hole. The support block 415 is provided to support the positioning screw 413, which serves to reinforce it and facilitates the positioning screw 413 pressing down on the gearbox housing without causing it to loosen.

[0047] The above are merely preferred embodiments of the present invention. Based on the above preferred embodiments, the present invention has the following preferred methods of use.

[0048] A method of using a processing device for a gearbox housing, the method comprising:

[0049] S1. First, install at least two positioning pins 3 into the mounting holes 5 on the positioning plate 2, and adjust the position of the positioning pins 3 according to the position of the positioning hole at the lower end of the gearbox body.

[0052] S4. Then, the mounting block 412 is driven to rise and fall by controlling the electric cylinder 411, so that the positioning screw 413 is coaxial with the positioning hole on the side wall of the gearbox.

[0053] S5. Rotate the positioning screw 413 by the handle 414 so that the positioning screw 413 enters the corresponding positioning hole.
