Description

Technical Field

[0001] This utility model relates to the field of mechanical technology, specifically to a double-sided machining fixture for bearing production. Background Technology

[0002] In the manufacturing process of bearing bushes, machining the inner and outer walls is a crucial step. However, traditional bearing bush machining fixtures often have some shortcomings. Clamping the bearing bushes is complex and time-consuming, and it's difficult to machine the inner and outer walls simultaneously, requiring multiple clamping operations. This not only reduces machining efficiency but also easily introduces errors from repeated clamping, affecting the machining accuracy of the bearing bushes. Furthermore, traditional fixtures have poor adaptability; different fixtures are often needed for bearing bushes of different sizes, increasing production costs and operational complexity.

[0003] Therefore, it is of great significance to provide a double-sided machining fixture for bearing production that can solve the problems existing in the current technology. Utility Model Content

[0004] In view of this, the purpose of this application is to provide a double-sided machining fixture for bearing production to solve the problem.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A double-sided machining fixture for bearing production includes a base, a cradle, two clamping mechanisms, a drive mechanism, and a rotary drive assembly.

[0007] Side plates are symmetrically fixed on both sides of the top of the base, providing a stable support foundation for the entire fixture. The two ends of the cradle are rotatably connected between the two side plates, allowing the cradle to rotate relative to the base, thereby adjusting the machining angle of the bearing bush.

[0008] Two clamping mechanisms are symmetrically arranged on the top of the cradle and can rotate relative to the cradle. Each clamping mechanism includes a base plate, two side frames, two movable plates, a support block, a cylinder, a clamping block, a lead screw, and a motor. The base plate is rotatably mounted on the cradle, providing a mounting platform for the other components of the clamping mechanism. The two side frames are symmetrically fixed on both sides of the top of the base plate, and a slide rod is fixedly connected between the two side frames, providing guidance for the sliding of the movable plates. The two movable plates are slidably fitted onto the slide rod, and the support block is fixedly arranged on the outer top of each movable plate to support the sides of the bearing. The cylinder is laterally fixed on the top of each side frame, and the clamping block is connected to the telescopic end of the cylinder and kept flush with the top of the movable plate. The cylinder drives the clamping block to extend and retract, thereby clamping and fixing the bearing. The lead screw is driven by a three-wheeled motor. The lead screw has two sections with opposite threads, each threaded to the bottom of one of the two movable plates. The three-wheeled motor is fixedly mounted on the bottom of one of the side frames. By driving the lead screw, the two movable plates move synchronously in opposite directions to accommodate bearings of different sizes. The cylinder is horizontally positioned, and its extension and retraction direction is consistent with the sliding direction of the movable plates, ensuring accurate clamping force direction.

[0009] The drive mechanism includes a housing located at the bottom of the cradle, a motor 1 installed inside the housing, and a bevel gear 2 driven by the motor 1. The bevel gear 1, which is fixedly connected to the bottom end of the base plate rotation shaft, meshes with the bevel gear 2. The motor 1 drives the base plate to rotate through the bevel gear transmission, thereby driving the clamping mechanism to rotate.

[0010] The rotation drive assembly includes a bevel gear four fixedly connected to the cradle rotation shaft, a motor two mounted on one side of the side plate, and a bevel gear three driven by the motor two. The bevel gear three meshes with the bevel gear four, and the motor two drives the cradle to rotate through the bevel gear transmission.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. Improved processing efficiency: This fixture adopts a cradle-type structure. The clamping mechanism can rotate, and the cradle can also rotate. With the fixture's stable clamping of the bearing, the bearing can be processed on both the inner and outer walls without multiple clamping operations. This reduces clamping time and procedures, and greatly improves processing efficiency.

[0013] 2. Ensuring Machining Accuracy: The distance between the movable plates is adjusted by a motor-driven lead screw, which can precisely adapt to bearings of different sizes. The cylinder-driven clamping block achieves stable clamping, ensuring that the bearings will not shift during machining. At the same time, the rotation of the cradle and clamping mechanism is driven by a motor through gear transmission, and the rotation angle is precisely controllable, effectively ensuring the machining accuracy of the bearings.

[0014] 3. Enhanced adaptability: The two-stage reverse thread design of the lead screw allows the two moving plates to move synchronously towards or away from each other. The spacing of the support blocks can be flexibly adjusted according to the size of the bearing bush, making it suitable for processing bearing bushes of different specifications. There is no need to change the fixture, which reduces production costs and operational difficulty.

[0015] 4. Easy to operate: The adjustment and drive of the entire fixture are automatically controlled by motors and cylinders, making operation simple and convenient and reducing the intensity of manual labor.

[0027] Please see Figure 1-3 This utility model provides a technical solution for a double-sided machining fixture for bearing production: a double-sided machining fixture for bearing production includes a base 1, a cradle 3, two clamping mechanisms 4, a drive mechanism and a rotary drive assembly.

[0028] The base 1 has side plates 2 symmetrically welded on both sides of the top, and the two ends of the cradle 3 are rotatably connected between the two side plates 2 through bearings.

[0029] Each clamping mechanism 4 has a base plate 41 rotatably mounted on the cradle 3 via bearings. Two side frames 43 are symmetrically welded to the top of the base plate 41, and a sliding rod 48 is welded between the two side frames 43. Two movable plates 42 are slidably fitted onto the sliding rod 48. A support block 44 is bolted to the outer top of each movable plate 42, and a cylinder 45 is bolted to the top of each side frame 43 laterally. The telescopic end of the cylinder 45 is connected to a clamping block 46, which remains flush with the top of the movable plate 42. A motor 49 is bolted to the bottom of one of the side frames 43, and a lead screw 47 is connected to the output end of the motor 49. The lead screw 47 has two sections of threads with opposite directions, which are respectively threaded to the bottom of the two movable plates 42.

[0030] The drive mechanism includes a housing 8 located at the bottom of the cradle 3. A motor 7 is bolted inside the housing 8. A bevel gear 6 is connected to the output end of the motor 7. A bevel gear 5 is keyed to the bottom end of the rotating shaft of the base plate 41. The bevel gear 5 meshes with the bevel gear 6.

[0031] The rotation drive assembly includes a bevel gear 11 keyed to the rotation shaft of the cradle 3, a motor 9 bolted to one side of the side plate 2, and a bevel gear 10 connected to the output end of the motor 9. The bevel gear 10 meshes with the bevel gear 11.

[0032] During operation, motor 49 is started according to the size of the bearing bush. Motor 49 drives lead screw 47 to rotate. Since the two threads of lead screw 47 rotate in opposite directions, the two movable plates 42 will move synchronously towards or away from each other under the guidance of slide rod 48. The position of support block 44 is adjusted to adapt to the size of the bearing bush. The bearing bush is placed on top of movable plate 42 so that the side of the bearing bush contacts support block 44. Cylinder 45 is started, and cylinder 45 drives clamping block 46 to extend, which cooperates with movable plate 42 to clamp and fix the bearing bush.

[0033] During processing, if it is necessary to adjust the machined surface of the bearing bush, start motor 29. Motor 29 drives bevel gear 310 to rotate, bevel gear 310 drives bevel gear 41 to rotate, which in turn drives cradle 3 to rotate, thereby adjusting the overall angle of the bearing bush. If it is necessary to rotate the angle of the bearing bush itself, start motor 17. Motor 17 drives bevel gear 26 to rotate, bevel gear 26 drives bevel gear 15 to rotate, which in turn drives base plate 41 and clamping mechanism 4 to rotate, thereby adjusting the angle of the bearing bush itself, so as to perform comprehensive machining on the inner and outer walls of the bearing bush.

[0034] The above description is merely a preferred embodiment of this utility model and does not limit the scope of protection of this utility model. For those skilled in the art, this utility model can have various modifications and variations. Any changes, modifications, substitutions, integrations, and parameter alterations made to these embodiments within the spirit and principles of this utility model, through conventional substitutions or methods that achieve the same function without departing from the principles and spirit of this utility model, fall within the scope of protection of this utility model.
