[0002] The reducer housing is a basic component of the reducer and also the matrix for arranging all parts of the reducer. The shape and dimensional accuracy of the housing and the accuracy of the mutual cooperation of each longitudinal axis determine the working performance of the entire reducer. During the processing of the reducer housing, a grinding tooling is required for processing.

[0003] The reducer housing generally consists of an upper housing and a lower housing. The outer surface of the upper housing of the reducer is mainly Figure 2 the arc surface 2, the inclined surface 3 and the connecting end face 1 in []. During processing, it is necessary to place the connecting end face of the upper housing of the reducer upward to ensure that the inside of the upper housing and the connecting end face can be ground and rinsed.

[0004] To ensure that the connecting end face is upward, the arc surface and the inclined surface need to be used as the supported surfaces during fixation. The traditional fixing method requires a large number of clamping blocks and cushion blocks to fix the upper housing, resulting in poor fixing effect, cumbersome operation and increased labor intensity of workers. Content of the Utility Model

[0005] The purpose of the utility model is to provide a positioning device for a reducer housing to solve the technical problem of inconvenient fixing of the upper housing in the prior art.

[0006] The technical problem to be solved by the utility model can be realized through the following technical solutions:

[0008] A limiting structure. There are two groups of the limiting structures, and each group includes a moving plate and an L-shaped plate. The moving plate is connected to the bottom of the corresponding L-shaped plate. A placing groove is formed between the two L-shaped plates. The two moving plates are movably and cooperatively connected to the top of the bottom plate through a driving structure, and clamping structures are arranged at both ends of each L-shaped plate;

Specific embodiments

[0024] The technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts belong to the scope of protection of the present utility model.

[0025] As Figures 1 - 4 shown, a positioning device for a reducer housing, used to fix the upper housing, includes a bottom plate 4. As Figure 2 shown, the upper housing includes a connecting end face 1, an arc surface 2 and an inclined surface 3. The shape of the upper housing belongs to the prior art and will not be described in detail here. The positioning device further includes a limiting structure and an auxiliary fixing structure;

[0026] There are two groups of limiting structures, and each group includes a moving plate 9 and an L-shaped plate 10. The moving plate 9 is fixedly connected to the bottom of the corresponding L-shaped plate 10. A placement groove is formed between the two L-shaped plates 10. The side of the connecting end face 1 of the upper housing is placed horizontally upward, so that the protruding part outside the connecting end face 1 is placed between the two L-shaped plates 10. The two moving plates 9 are movably and cooperatively connected to the top of the bottom plate 4 through a driving structure, and clamping structures are provided at both ends of each L-shaped plate 10;

[0027] The auxiliary fixing structure is connected to the top of the bottom plate 4 and cooperates with the bottom of the upper housing.

[0028] In some specific implementation schemes, as Figure 1As shown, in order to facilitate the L-shaped plate 10 to support L-shaped plates 10 of different sizes, the driving structure includes a bidirectional screw 6 and a limiting rod 8. Vertical plates 5 are fixedly arranged at both ends of the top of the bottom plate 4. The bidirectional screw 6 is rotatably connected between the two vertical plates 5. A motor 7 for driving the bidirectional screw 6 to rotate is arranged on one of the vertical plates 5. The motor 7 is fixed on the vertical plate 5, and the output end of the vertical plate 5 is fixedly connected to the bidirectional screw 6. A limiting rod 8 parallel to the bidirectional screw 6 is fixedly connected between the two vertical plates 5. Both ends of the bidirectional screw 6 are respectively threadedly connected to the corresponding moving plates 9. The limiting rod 8 passes through the moving plates 9 and is slidably connected to the moving plates 9. Starting the motor 7 drives the bidirectional screw 6 to rotate, causing the two moving plates 9 to move towards each other, so that the two L-shaped plates 10 can support the protruding parts of the connecting end faces 1 at both ends of the upper shell, and can support upper shells of different sizes.

[0029] In some specific implementation schemes, such as Figure 4 As shown, in order to fix the upper shell in the horizontal direction, the clamping structure includes baffles 11, hydraulic cylinders 12 and abutting blocks 13. There are two baffles 11, which are respectively fixedly connected to both ends of the L-shaped plate 10. The hydraulic cylinders 12 are fixedly connected to the sides of the baffles 11 close to the middle. The driving ends of the hydraulic cylinders 12 are fixedly connected to the abutting blocks 13. The abutting blocks 13 are matched with the sides of the connecting end face 1. Starting the hydraulic cylinders 12 simultaneously, the hydraulic cylinders 12 drive the abutting blocks 13 to clamp the side of the upper shell, preventing the upper shell from having a horizontal displacement during processing.

[0030] In some specific implementation schemes, such as Figure 1 As shown, in order to facilitate the fixation of the upper shell in the vertical direction, the auxiliary fixing structure includes driving elevators 14, inclined plates 15 and suction cups 16. The suction cups 16 are vacuum suction cups 16. There are two driving elevators 14, which are both fixedly connected to the top of the bottom plate 4. The two driving elevators 14 are arranged along the width direction of the connecting end face 1. Hinge seats are arranged at the tops of the driving elevators 14. The two driving elevators 14 are rotatably connected to the inclined plate 15 through the hinge seats. The inclined plate 15 can rotate around the hinge seats along the width direction of the upper shell. A number of suction cups 16 are fixedly connected to the side of the inclined plate 15 away from the driving elevators 14. The inclined plate 15 is inclined and adsorbed and matched with the inclined surface 3. The suction cups 16 are matched with the bottom of the upper shell. One end of the suction cup 16 away from the upper shell is connected to a vacuum pump, which is used to make the suction cup 16 adsorb and fix the inclined surface 3 of the upper shell.

[0031] In some specific implementation schemes, such as Figure 3 As shown, in order to prevent the L-shaped plate 10 from affecting the grinding of the upper shell, the height of the side wall of the L-shaped plate 10 is lower than the height of the connecting end face 1, so that the grinding disc directly grinds the contact surface of the upper shell, preventing the side wall of the L-shaped plate 10 from being higher than the contact surface, thus generating grinding dead corners.

[0032] In some specific implementation schemes, such asFigure 3 As shown, in order to enhance the supporting force for the L-shaped plate 10, reinforcing rods 17 are fixedly arranged between both sides of the moving plate 9 and the L-shaped plate 10. The reinforcing rods 17 are used to support both sides of the corresponding L-shaped plate 10.

[0033] For the convenience of those skilled in the art to understand the embodiments of this solution, the working principle of this solution will be briefly described below in combination with a specific application scenario:

[0034] During actual use, the motor 7 is started, and the motor 7 drives the bidirectional screw 6 to rotate. Since the bidirectional screw 6 is threadedly connected to the moving plate 9, and the moving plate 9 is slidably connected to the limiting rod 8, when the motor 7 rotates, the moving plate 9 drives the L-shaped plates 10 to move towards each other, making the length of the placement groove formed by the L-shaped plates 10 correspond to the length of the contact end face 1 of the upper shell. The two L-shaped plates 10 complete the support for the upper shell. Then, the hydraulic cylinder 12 is started to drive the abutting block 13 to move towards the upper shell until the abutting block 13 clamps the side of the upper shell, so that the upper shell will not move horizontally. Finally, the driving elevator 14 is started to move upward until the suction cup 16 fits the inclined surface 3 of the upper shell. The vacuum pump connected to the suction cup 16 is started to work, and the air inside the suction cup 16 is pumped out to form a vacuum state. The suction cup 16 generates a strong adsorption force on the upper shell, so that the upper shell will not move up and down during processing. This fixing method is simple to operate, can expose the inside and the connection end face 1 of the upper shell, is convenient for grinding and cleaning operations, and can fix upper shells of different sizes, with strong applicability.

[0035] The above has described several embodiments of the present invention in detail, but the embodiments of the present invention are not limited thereto and cannot be considered as used to limit the scope of implementation of the present invention. All equal changes and improvements made according to the scope of the present invention application should still fall within the scope covered by the patent of the present invention.
