Description

Technical Field

[0002] In the production and processing of motor housings, fixtures are required to perform operations such as positioning, drilling, milling, reaming, and tapping on the motor housing blanks. When the existing equipment is in operation, the fixture is tightly clamped to the outside of the machine housing. Excessive or uneven clamping force will cause elastic deformation of the machine housing. Although the dimensions processed under the clamped state are qualified, once the fixture is removed, the machine housing will spring back, which will cause out-of-tolerance roundness and inaccurate dimensions. In addition, the fixture cannot fully avoid the tool path, causing interference between the fixture body and the tool. Multiple clamping is required. The chips generated during processing are easy to accumulate on the clamping elements, which will lead to inaccurate positioning of subsequent workpieces and affect the subsequent cutting operations. Based on this, this utility model discloses a fixture for one-time machining of a servo motor housing. Utility Model Content

[0017] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0018] Therefore, this utility model provides a fixture for one-time machining of servo motor housings. (See attached image) Figures 1-3 , Figure 5 As shown, it includes a support frame 1, a rotating seat 2 is provided on the upper part of the support frame 1, a cylinder 3 is installed on the rotating seat 2, a clamping plate 4 is installed on the telescopic end of the cylinder 3, a radial clamping assembly is installed on the clamping plate 4, the radial clamping assembly includes a structural cylinder 5, structural cylinders 5 are fixedly connected to the clamping surfaces of the clamping plate 4, structural cavities 6 are opened on the opposite surfaces of the two structural cylinders 5, a transverse fixed shaft 7 is installed inside the structural cavity 6, a swing rod 8 is installed symmetrically outside the cross section of the fixed shaft 7, lifting holes are opened on the upper and lower end faces of the structural cylinder 5, lifting rods 9 are provided inside the upper and lower lifting holes, structural holes are opened on the rod body of the lifting rod 9, the lifting rod 9 is sleeved outside the cross section of the swinging long end of the corresponding position swing rod 8 through the structural holes, a connecting frame 10 is installed on the end of the lifting rod 9 that extends outward, a rubber support block 11 is fixedly installed on the short rod of the connecting frame 10, and an auxiliary cleaning component is installed on the support frame 1. When the swing rod 8 rotates, with the cooperation of the structural hole, the lifting rod 9 drives the connecting frame 10 and the rubber support block 11 to rise and fall vertically, so as to provide radial support for the inside of the housing and reduce the excessive clamping of the fixture on the outside of the housing. The surface of the rubber support block 11 has a certain friction force to prevent the motor housing from rotating during the support process of the rubber support block 11.

[0019] A push plate 15 is positioned inside the structural cavity 6, away from the clamping plate 4. An insertion slot 16 is provided on one side of the structural cylinder 5. A structural piece is fixed to the push plate 15 near the insertion slot 16, and the structural piece is inserted into the insertion slot 16. The edge of the push plate 15 slides along the inner wall of the structural cavity 6. A structural hole is provided on the push plate 15, and the push plate 15 is sleeved outside the cross-section of the swing rod 8 through the structural hole. The forward and backward movement of the push plate 15 controls the opening and closing degree of the two rods of the swing rod 8, thereby adjusting the working position of the lifting rod 9, the connecting frame 10, and the rubber support block 11.

[0020] Insert rods 17 are fixedly connected to the opposite end faces of the two structural cylinders 5 at positions away from the insertion slots 16. The insert rods 17 can be inserted into the corresponding insertion slots 16. The insert rods 17 can provide driving force for the movement of the push plate 15 when the structural cylinders 5 come close to each other.

[0021] Inside the structural cavity 6, symmetrically fixed limit shafts 12 are positioned near both sides. Lifting blocks 13 are slidably sleeved on the outer surface of the limit shafts 12. The lifting blocks 13 are connected to corresponding lifting rods 9. Limiting springs 14 are sleeved on the outer surface of the limit shafts 12, with one end connected to the inner wall of the structural cavity 6 and the other end connected to the lifting blocks 13. After the lifting rod 9 moves the rubber support block 11 away from the structural cylinder 5, the limiting spring 14 is compressed and generates a reaction force. This reaction force causes the lifting blocks 13 and lifting rod 9 to tend to return to their original positions. After the insertion rod 17 is withdrawn from the opening of the insertion slot 16, the pushing force of the insertion rod 17 on the push plate 15 is removed. With the cooperation of the reaction force of the limiting spring 14, the lifting block 13 drives the lifting rod 9, connecting frame 10, and rubber support block 11 to return to their original positions, causing the swing rod 8 to rotate and return to its original position. This, in turn, causes the push plate 15 to move outward and return to its original position, facilitating the next clamping operation.

[0022] The clamping plate 4 has clearance grooves 18 on all four sides, and the clearance grooves 18 penetrate through the thickness of the plate body of the limiting spring 14.

[0023] During operation, the radial clamping assembly allows the motor housing to be placed between the structural cylinders 5. Activating cylinder 3 causes clamping plate 4 to move the structural cylinders 5 towards each other, clamping them together. The structural cylinders 5 move into the motor housing, and the insertion rod 17 inserts into the insertion slot 16, contacting the structural piece of the push plate 15. As the structural cylinders 5 approach each other, the insertion rod 17 applies a pushing force to the push plate 15. The push plate 15 pushes the swing rod 8 to rotate around the fixed shaft 7, causing the long ends of the swing rods 8 to move away from each other. This causes the lifting rod 9 to push the connecting frame 10 and the rubber support block 11 away from the structural cylinders 5. The lifting block 13 moves accordingly, causing the limiting spring 14 to be compressed and generate a reaction force. This reaction force causes the lifting block 13 and the lifting rod 9 to tend to return to their original position. The rubber support block 11 is tightly attached to the inner arc surface of the motor housing, providing radial support to the motor housing and greatly reducing clamping deformation.

[0024] Further, see Figure 1 , Figures 4-5As shown, the auxiliary cleaning assembly includes a structural frame 19. The structural frame 19 is connected to one vertical surface of the support frame 1. Fixed rods 20 are fixedly connected between the structural frames 19. Movable seats 21 are slidably fitted onto the outer surfaces of both ends of the fixed rods 20. Suction pipes 22 are provided on opposite surfaces of the movable seats 21. Multiple suction nozzles 23 are equidistantly installed on the suction pipes 22 near the clamping plate 4. A connecting block 24 is connected to the end of the suction pipe 22 away from the movable seat 21. The connecting block 24 is fitted onto the outer surface of the fixed rod 20 through a sliding hole. The movable seats 21 and connecting blocks 24 ensure smooth movement of the suction pipes 22 on the fixed rods 20. The suction nozzles 23 are obliquely installed on the suction pipes 22, with the working end of the suction nozzle 23 always facing the corresponding clamping plate 4 and structural cylinder 5, ensuring effective operation of the suction nozzles 23.

[0025] A collection box 26 is provided at the bottom of the support frame 1. An air pump 27 is installed on the collection box 26. A connecting hose 25 is installed on the air extraction pipe 22. The end of the connecting hose 25 extends through the sliding groove on the structural frame 19 and is connected to the air pump 27.

[0026] A limiting groove 28 is provided on the movable seat 21 near the clamping plate 4. Arc-shaped pieces 29 are fixed to all four structural surfaces of the clamping plate 4. The rotation trajectory of the arc-shaped pieces 29 passes through the opening space of the limiting groove 28. The cooperation between the arc-shaped pieces 29 and the limiting groove 28 allows the suction pipe 22 and the suction nozzle 23 to move with the clamping plate 4, ensuring the smooth operation of the suction nozzle 23.

[0027] A gear tooth 30 is fixed to the outer end of one side of the rotating seat 2. A drive motor 31 is mounted on the plate structure surface of the support frame 1 near the gear tooth 30. A gear 32 is mounted on the end of the output shaft of the drive motor 31, and the gear 32 meshes with the gear tooth 30. This provides driving force for the rotation of the clamping plate 4.

[0028] A limit ring 33 is provided near the clamping plate 4 of the cylinder 3. The limit ring 33 is rotatably sleeved outside the cross section of the cylinder 3. An inclined support rod is provided at the bottom of the limit ring 33, and the bottom of the inclined support rod is fixed to the plate of the support frame 1.

[0029] During operation, thanks to the structural design of the auxiliary cleaning components, when the clamping plate 4 pushes the structural cylinder 5 to move, the clamping plate 4, in cooperation with the limiting groove 28 and the arc-shaped piece 29, drives the moving seat 21 and the suction pipe 22 to move along the fixed rod 20, so that the working range of the suction nozzle 23 always faces the clamping plate 4 and the structural cylinder 5. After the top of the machine housing is processed, the drive motor 31 operates, and with the cooperation of the gear teeth 30, the gear 32 drives the rotating seat 2 and the cylinder 3 to rotate. The clamping plate 4 drives the arc-shaped piece 29 to rotate 90 degrees towards the suction pipe 22. At the same time, the air pump 27 operates, and the port of the suction nozzle 23 generates suction force, so that the chips on the clamping surface of the clamping plate 4 and the machine housing processing surface are sucked into the interior of the suction pipe 22 and collected in the collection box 26 through the connecting hose 25, preventing the chips from accumulating on the clamp and ensuring timely cleaning of chips during processing or tool change intervals.

[0030] In summary, this effectively solves the problems of existing equipment where the fixture is tightly clamped to the outside of the machine housing, and excessive or uneven clamping force can cause elastic deformation of the machine housing. Although the dimensions processed under clamping conditions are qualified, once the fixture is removed, the machine housing springs back, causing out-of-tolerance roundness and dimensional inaccuracies. Furthermore, the fixture cannot adequately avoid the tool path, causing interference between the fixture body and the tool, requiring multiple clamping operations. The chips generated during processing tend to accumulate on the clamping elements, leading to inaccurate positioning of subsequent workpieces and affecting subsequent cutting operations.
