Description

Technical Field

[0001] This utility model relates to the field of reducer housing processing technology, specifically a reducer housing machining tooling. Background Technology

[0002] A speed reducer is a mechanical transmission device whose core function is to convert the high-speed, low-torque output of a power source into a low-speed, high-torque output through transmission structures such as gears and worm gears, thereby matching the working requirements of actual equipment. Its outer casing is used to protect the internal transmission components and provide necessary support and protection.

[0003] When drilling holes in the reducer housing, it needs to be fixed by a fixture. Some reducer housings are designed to be cylindrical, and the fixtures are usually positioned by clamping the cylindrical sides with two side plates. Therefore, when drilling longitudinal holes in the reducer housing, the reducer housing will deflect within the fixture, which will affect the drilling accuracy. Therefore, further improvements can be made. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides the following technical solution: a machining fixture for a reducer housing, comprising a housing, the top of which has a centrally symmetrical sliding groove and a limiting groove. Inside the housing, corresponding to the sliding groove and the limiting groove, are clamping and positioning components for holding and fixing the reducer housing. Inside the housing is a servo motor for driving the clamping and positioning components. A gear is fixedly mounted on the top of the output shaft of the servo motor. Inside the housing, on both sides of the output shaft of the servo motor, are locking and clamping components for locking and positioning the servo motor. By starting the servo motor and driving the gear to rotate, the clamping and positioning components are driven, thus clamping and fixing the reducer housing. Simultaneously, the locking and clamping components lock and clamp the output shaft of the servo motor, improving the stability of the clamping. Afterward, the reducer housing can be machined.

[0005] As an optimization, the clamping and positioning assembly includes a limiting rod fixedly installed inside the housing, a rack plate slidably sleeved on the outer side of the limiting rod, and the rack plate meshing with a gear, a support plate fixedly installed at the end of the rack plate, and the support plate slidably connected in a groove, a bracket fixedly installed at the top of the support plate, and a clamping component for clamping and positioning on both sides of the reducer housing is fixedly installed at the top of the bracket.

[0006] As an optimization, a limiting block is fixedly installed at one bottom end of the bracket, and the limiting block is slidably connected in the limiting groove.

[0007] As an optimization, the clamping member is an arc-shaped clamping plate, and arc grooves are provided on both sides of the inner arc of the clamping plate. Several sets of limiting strips are installed at equal intervals on one side of the inner arc of the clamping plate.

[0008] As an optimization, the limiting strip is a retaining strip, and a threaded cylinder is fixedly installed on one side of the back of both ends of the retaining strip. A slider is fixedly installed on one side of the back of the threaded cylinder, and the slider is slidably connected in the arc groove. A through hole is opened at the center of the threaded cylinder corresponding to the slider and the retaining strip, and a fastening screw is screwed into the threaded cylinder.

[0009] As an optimization, the locking assembly includes a mounting bracket fixedly installed inside the housing. An electric push rod is fixedly installed on the top of the mounting bracket. An arc plate is fixedly installed on the telescopic end of the electric push rod, and the arc plate is clamped on both sides of the output shaft of the servo motor. A friction plate to increase friction is provided on the inner side of the arc plate.

[0010] As an optimization, a fixing ring is fixedly installed on the outer side of the output shaft of the servo motor corresponding to the two side arc plates, and the outer side of the fixing ring is an uneven friction surface. The friction surface further increases the friction force and improves the locking effect.

[0011] The beneficial effects of this utility model are:

[0012] 1. The machining fixture for the reducer housing uses a servo motor to drive the gears to rotate, which in turn causes the rack plates on both sides to slide relative to each other along the outer side of the limit rod. This pulls the brackets on both sides closer together, which in turn causes the clamping plates on both sides to move closer together and clamp onto both sides of the reducer housing. At the same time, the limit strip is embedded into the heat dissipation groove of the reducer housing, thereby limiting the reducer housing and preventing its rotational deviation from affecting the machining accuracy.

[0013] 2. This gearbox housing machining fixture allows the slider to slide along the inner wall of the arc groove by pulling the clamping strip, thus facilitating the adjustment of the distance between adjacent clamping strips. By turning the fastening screw, the slider rotates inside the arc groove threaded cylinder, thus securing it against the bottom wall of the arc groove for positioning. This allows for adjustment of the distance between adjacent clamping strips, making it suitable for heat dissipation slots of different gearbox housing models and improving practicality.

[0020] In the description of this application, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-2 A machining fixture for a reducer housing includes a housing 1. The top of the housing 1 has a centrally symmetrical sliding groove 2 and a limiting groove 3. Inside the housing 1, corresponding to the sliding groove 2 and the limiting groove 3, there is a clamping and positioning assembly 4 for clamping and fixing the reducer housing. Inside the housing 1, there is a servo motor 5 for driving the clamping and positioning assembly 4. A gear 6 is fixedly installed at the top of the output shaft of the servo motor 5. Inside the housing 1 and on both sides of the output shaft of the servo motor 5, there are locking and clamping assemblies 7 for locking and positioning the servo motor 5. By starting the servo motor 5 and driving the gear 6 to rotate, the clamping and positioning assembly 4 can be driven, thus clamping and fixing the reducer housing. At the same time, the locking and clamping assembly 7 locks the output shaft of the servo motor 5, thereby improving the stability of the clamping. After that, the reducer housing can be machined.

[0023] Please see Figure 2-3The clamping and positioning assembly 4 includes a limiting rod 8 fixedly installed inside the housing 1. A rack plate 9 is slidably sleeved on the outer side of the limiting rod 8, and the rack plate 9 is meshed with a gear 6. A support plate 10 is fixedly installed at the end of the rack plate 9, and the support plate 10 is slidably connected in the slide groove 2. A bracket 11 is fixedly installed at the top of the support plate 10. A limiting block 12 is fixedly installed at one bottom end of the bracket 11, and the limiting block 12 is slidably connected in the limiting groove 3. The sliding of the bracket 11 will drive the limiting block 12 to slide along the inner wall of the limiting groove 3, thereby limiting the other end of the bracket 11, making the relative sliding of the two brackets 11 more stable. A clamping component for clamping and positioning on both sides of the reducer housing is fixedly installed at the top of the bracket 11. By starting the servo motor 5 to drive the gear 6 to rotate, the rack plates 9 meshing with the gear 6 on both sides can be driven to slide along the outer side of the limiting rod 8, thereby pulling the two brackets 11 on both sides closer to each other, thereby driving the clamping component to move closer to each other and clamping and positioning on both sides of the reducer housing.

[0024] Please see Figure 3-4 The clamping component is an arc-shaped clamping plate 13, and arc grooves 14 are provided on both sides of the inner arc of the clamping plate 13. Several sets of limiting strips are installed at equal intervals on one side of the inner arc of the clamping plate 13. When the clamping plates 13 on both sides are close to each other and clamped on the reducer housing, the limiting strips will be embedded in the heat dissipation groove of the reducer housing, thereby limiting the reducer housing and preventing it from rotating and shifting, which would affect the machining accuracy.

[0025] Please see Figure 3-4 The limiting strip is a retaining strip 15, and a threaded cylinder is fixedly installed on one side of the back of both ends of the retaining strip 15. A slider 16 is fixedly installed on one side of the back of the threaded cylinder, and the slider 16 is slidably connected in the arc groove 14. A through hole 17 is opened at the center of the threaded cylinder corresponding to the slider 16 and the retaining strip 15. A fastening screw 18 is screwed into the threaded cylinder. By pulling the retaining strip 15, the slider 16 will slide along the inner wall of the arc groove 14, which makes it easy to adjust the distance between adjacent retaining strips 15. By turning the fastening screw 18 in the threaded cylinder of the arc groove 14, it can be pressed against the bottom wall of the arc groove 14 for positioning, which makes it easy to be used in the heat dissipation slots of different models of reducer housings and improves practicality.

[0026] Please see Figure 5The locking assembly 7 includes a mounting bracket 19 fixedly installed inside the housing 1. An electric push rod 20 is fixedly installed on the top of the mounting bracket 19. An arc plate 21 is fixedly installed on the telescopic end of the electric push rod 20, and the arc plate 21 is clamped on both sides of the output shaft of the servo motor 5. The inner side of the arc plate 21 is provided with friction plates to increase friction. A fixing ring is fixedly installed on the outer side of the output shaft of the servo motor 5 corresponding to the two arc plates 21. The outer side of the fixing ring is an uneven friction surface. By activating the electric push rod 20, the arc plate 21 can be driven to clamp on both sides of the output shaft, thereby locking and limiting the output shaft to prevent the gear 6 from rotating accidentally and affecting the clamping and positioning effect. The friction surface further increases the friction and improves the locking and limiting effect.

[0027] In use, the servo motor 5 is started to drive the gear 6 to rotate, which in turn drives the rack plates 9 on both sides to slide relative to each other along the outer side of the limit rod 8. This will pull the brackets 11 on both sides closer together, which will then drive the clamping plates 13 on both sides closer together and clamp them on both sides of the reducer housing. At the same time, the limit strip will be embedded in the heat dissipation groove of the reducer housing, thus limiting the reducer housing. Then, by starting the electric push rod 20, the arc plate 21 can be driven to clamp on both sides of the output shaft for locking and limiting.

[0028] Pulling the clip 15 will cause the slider 16 to slide along the inner wall of the arc groove 14, thereby facilitating the adjustment of the distance between adjacent clips 15. By turning the fastening screw 18, it can rotate inside the threaded cylinder of the arc groove 14 and be positioned against the bottom wall of the arc groove 14, thereby adjusting the distance between adjacent clips 15.

[0029] In summary, the machining fixture for the reducer housing, by starting the servo motor 5 to drive the gear 6 to rotate, will cause the rack plates 9 on both sides to slide relative to each other along the outer side of the limiting rod 8. This will pull the brackets 11 on both sides closer together, which will in turn cause the clamping plates 13 on both sides to move closer together and clamp them on both sides of the reducer housing. At the same time, it will cause the limiting strip to be embedded in the heat dissipation groove of the reducer housing, thereby limiting the reducer housing and preventing its rotational deviation from affecting the machining accuracy.

[0030] Pulling the clip 15 will cause the slider 16 to slide along the inner wall of the arc groove 14, thus facilitating the adjustment of the distance between adjacent clips 15. By turning the fastening screw 18, it can rotate inside the threaded cylinder of the arc groove 14 and be positioned against the bottom wall of the arc groove 14, thereby adjusting the distance between adjacent clips 15. This makes it suitable for heat dissipation slots of different models of reducer housings, improving practicality.
