Description

Technical Field

[0001] This utility model relates to the technical field of speed reducer production and processing equipment, and in particular to a machine tool for processing speed reducer adjustment rings. Background Technology

[0002] As a key component in mechanical transmission systems, speed reducers are widely used in various fields of industrial production, such as machine tools, automobiles, aerospace, and mining machinery. Within the internal structure of a speed reducer, the adjusting ring is an indispensable and crucial part. It is typically installed between the gear sets and its main function is to precisely adjust the gear meshing clearance. Appropriate gear meshing clearance is essential for the normal operation of the speed reducer; therefore, the machining accuracy of the adjusting ring directly determines its effectiveness in adjusting the gear meshing clearance, thus affecting the overall performance and reliability of the speed reducer.

[0003] However, existing machine tools still have certain limitations when machining adjustment rings.

[0004] For example, the equipment has poor versatility: existing processing equipment is often designed for specific models or specifications of adjustment rings. When different models or specifications of adjustment rings need to be processed, a lot of adjustments and modifications need to be made to the equipment, and even some parts need to be replaced. This brings certain inconveniences to the production of enterprises and increases the maintenance costs of the equipment.

[0005] For example, machining accuracy is difficult to guarantee: the positioning accuracy of existing machine tools is relatively low. When machining key dimensions of the adjusting ring, such as inner diameter, outer diameter, and end face perpendicularity, runout and axial movement are prone to occur, resulting in dimensional deviations and shape errors. Utility Model Content

[0006] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a machine tool for machining reducer adjustment rings, so as to solve the problems of poor equipment versatility and difficulty in guaranteeing machining accuracy.

[0007] A machine tool for machining reducer adjustment rings includes a frame, on which a platform device and a machining device are provided. The platform device is used to fix the workpiece to be machined and drive the workpiece to rotate, and the machining device is used to machine the workpiece.

[0008] The platform device includes a rotating device mounted on a frame and a positioning mechanism mounted on the rotating device. The positioning mechanism includes a base and three sets of positioning seats arranged in an equilateral triangle with their vertices distributed on the base. A rotating arm is rotatably mounted on the outer side of each set of positioning seats, and a positioning block is connected to the top of each rotating arm.

[0009] It also includes a drive assembly rotatably mounted on the base and located in the center of the three sets of positioning seats. The drive assembly is connected to the lower part of the three rotating arms by three connecting rods. The drive assembly drives the rotating arms to swing inward or outward through the connecting rods, so that the positioning block located at the top of the rotating arm abuts against the workpiece, thereby clamping the workpiece inward or opening it outward to accommodate workpieces of different specifications and models.

[0010] In this invention, the side of the positioning block that abuts against the workpiece is provided with an arc-shaped surface for horizontal positioning of the workpiece. When the arc-shaped surface abuts against the workpiece, it can drive the workpiece to move closer to the center of the arc-shaped surface. This, together with the three positioning blocks arranged in an equilateral triangle, achieves horizontal positioning of the workpiece.

[0011] In this utility model, the driving assembly includes a rotating component rotatably mounted on a base, a movable component and a limiting component cooperating on the rotating component. The outer surface of the rotating component is provided with a threaded structure. The movable component is sleeved on the rotating component and threadedly engaged with the rotating component. The limiting component is threadedly engaged on the top of the rotating component. When the rotating component is rotated, the movable component can be driven to move up and down. The connecting rod is hinged to the outside of the movable component.

[0012] Furthermore, the top of the rotating component extends upward with a hexagonal structure, and the lower part of the rotating component is provided with a limiting structure for restricting the movement distance of the movable component. The space between the limiting structure and the limiting component is the movement space of the movable component. When the movable component moves to a certain position and fixes the workpiece, the limiting component is tightened so that it abuts against the top of the movable component.

[0013] In this utility model, the processing device includes an inner and outer diameter processing mechanism, an upper end face processing mechanism, and a lower end face processing mechanism that are installed around the platform device. The inner and outer diameter processing mechanism is used to process the inner or outer diameter of the workpiece, and the upper end face processing mechanism and the lower end face processing mechanism respectively process the upper and lower end faces of the workpiece.

[0014] Furthermore, the inner and outer diameter machining mechanism, the upper end face machining mechanism, and the lower end face machining mechanism each include a cutting head for machining the workpiece, a driver for driving the cutting head to rotate, and a moving mechanism for driving the cutting head to move. The cutting head is mounted on the driver, the driver is mounted on the moving mechanism, and the moving mechanism can drive the cutting head to move up and down, left and right, and forward and backward.

[0015] In this invention, the rotating device includes a rotator fixed on the frame and a fixed plate mounted on the rotator. The positioning mechanism is fixed on the fixed plate. The rotator drives the fixed plate to rotate, thereby driving the positioning mechanism to rotate, and thus driving the workpiece to rotate.

[0016] The beneficial effects of this utility model are:

[0017] This machine tool for machining reducer adjusting rings uses a drive assembly to move a rotating arm and positioning block to achieve internal clamping or external expansion positioning of the workpiece. It can adapt to workpieces of different specifications and models, effectively solving the problem of poor versatility of existing processing equipment, reducing the workload of equipment adjustment and modification, and lowering maintenance costs. At the same time, the arc-shaped surface on the positioning block can achieve horizontal positioning of the workpiece. Combined with a reasonable layout of the processing device, it helps to improve processing accuracy and avoid dimensional deviations and shape errors caused by low positioning accuracy of existing machine tools. This improves the processing quality of reducer adjusting rings and ensures the performance and reliability of the reducer. Attached Figure Description

[0028] Please see Figures 1 to 6 :

[0029] This embodiment discloses a machine tool for machining a reducer adjustment ring, including a frame 1, a platform device 2 and a machining device 3 on the frame 1, the platform device 2 is used to fix the workpiece to be processed and to drive the workpiece to rotate, and the machining device 3 is used to process the workpiece. Specifically, the platform device 2 includes a rotating device 21 mounted on the frame 1 and a positioning mechanism 22 mounted on the rotating device 21. The positioning mechanism 22 includes a base 221 and three sets of positioning seats 222 arranged in an equilateral triangle with their vertices distributed on the base 221. A rotating arm 223 is rotatably mounted on the outer side of each set of positioning seats 222, and a positioning block 224 is connected to the top of each rotating arm 223. The positioning mechanism 22 also includes a drive assembly 225 rotatably mounted on the base 221 and located in the center of the three sets of positioning seats 222. The drive assembly 225 is connected to the lower part of the three rotating arms 223 by three connecting rods 226. The drive assembly 225 drives the rotating arms 223 to swing inward or outward through the connecting rods 226, while the positioning block 224 located at the top of the rotating arm 223 abuts against the workpiece to clamp the workpiece inward or open it outward.

[0030] In addition, the side of the positioning block 224 that abuts against the workpiece is also provided with an arc-shaped surface 2241 for horizontal positioning of the workpiece. When the arc-shaped surface 2241 abuts against the workpiece, it can drive the workpiece to move closer to the middle position of the arc-shaped surface 2241. With the help of three positioning blocks 224 distributed in an equilateral triangle, the workpiece can be horizontally positioned.

[0031] Furthermore, such as Figure 5As shown, the positioning seat 222 has a hinge seat 2221 on its outer side. The rotating arm 223 has an L-shaped structure. The positioning block 224 is hinged to the top of the rotating arm 223, and the middle part of the rotating arm 223 is hinged to the hinge seat 2221. The end of the rotating arm 223 points towards the drive assembly 225, and the connecting rod 226 is hinged to the bottom of the rotating arm 223. When the drive assembly 225 rises, it pulls the bottom of the rotating arm 223 inward through the connecting rod 226, while the positioning block 224 at the top of the rotating arm 223 expands outward. When the drive assembly 225 descends, it pushes the bottom of the rotating arm 223 outward through the connecting rod 226, while the positioning block 224 at the top of the rotating arm 223 retracts inward.

[0032] Furthermore, such as Figure 5 As shown, the drive assembly 225 includes a rotating component 2251 rotatably mounted on a base 221, a movable component 2252 and a limiting component 2253 cooperating on the rotating component 2251. The outer surface of the rotating component 2251 is provided with a threaded structure. The movable component 2252 is sleeved on the rotating component 2251 and threadedly engaged with it. The limiting component 2253 is threadedly engaged on the top of the rotating component 2251. The limiting component 2253 is preferably a hexagonal nut. Rotating the rotating component 2251 can drive the movable component 2252 to move up and down. The connecting rod 226 is hinged to the outside of the movable component 2252. When the movable component 2252 moves up and down, it can pull or push the connecting rod 226. In addition, to facilitate the rotation of the rotating component 2251, a hexagonal structure 22511 extends upward from the top of the rotating component 2251. The rotating component 2251 can be rotated by putting a wrench or a screwdriver onto the hexagonal structure 22511.

[0033] Furthermore, such as Figure 5 As shown, the lower part of the rotating member 2251 is provided with a limiting structure 22512 for limiting the movement distance of the movable member 2252. The space between the limiting structure 22512 and the limiting member 2253 is the movement space of the movable member 2252. In addition, when the movable member 2252 moves to a certain position and fixes the workpiece, the limiting member 2253 can be tightened to make it abut against the top of the movable member 2252, thereby improving the fixing effect.

[0034] In this embodiment, as Figure 1As shown, the processing device 3 includes an inner and outer diameter processing mechanism 31, an upper end face processing mechanism 32, and a lower end face processing mechanism 33, which are installed around the platform device 2. The inner and outer diameter processing mechanism 31 is used to process the inner or outer diameter of the workpiece. Specifically, when the positioning block 224 opens and fixes the workpiece outward, the inner and outer diameter processing mechanism 31 can process the outer diameter of the workpiece. When the positioning block 224 clamps and fixes the workpiece inward, the inner and outer diameter processing mechanism 31 can process the inner diameter of the workpiece. The upper end face processing mechanism 32 and the lower end face processing mechanism 33 respectively process the upper and lower end faces of the workpiece.

[0035] Furthermore, such as Figure 2 As shown, the inner and outer diameter machining mechanism 31, the upper end face machining mechanism 32, and the lower end face machining mechanism 33 all include a cutting head 301 for machining the workpiece, a driver 302 for driving the cutting head 301 to rotate, and a moving mechanism 303 for driving the cutting head 301 to move. The cutting head 301 is mounted on the driver 302, and the driver 302 is mounted on the moving mechanism 303. The moving mechanism 303 can drive the cutting head 301 to move up and down, left and right, and back and forth to adapt to workpieces of different specifications and models. The driver 302 is a motor. The specific structure and working principle of the moving mechanism 303 can be found in the adjustment component of a high-precision multi-axis machining center suitable for multiple specifications disclosed in Chinese Patent Publication No. CN207824533U, which will not be elaborated further here.

[0036] In this embodiment, as Figure 6 As shown, the rotating device 21 includes a rotator 211 fixed on the frame 1 and a fixed plate 212 mounted on the rotator 211. The positioning mechanism 22 is fixed on the fixed plate 212. The rotator 211 is a drive motor. The rotator 211 drives the fixed plate 212 to rotate, thereby driving the positioning mechanism 22 to rotate in plane, which in turn drives the workpiece to rotate.
