[0002] The main reducer housing is a key component of the transmission system, and the flatness and precision of its end face are crucial to the performance of the entire system. To ensure machining quality, a special fixture is usually required to position and clamp the reducer housing during end face turning.

[0003] Existing turning fixtures mostly use manual or semi-manual clamping methods, such as tightening with bolts or locking with eccentric wheels. This method is acceptable for single-piece and small-batch production, but in mass production scenarios, it is cumbersome, time-consuming, and heavily reliant on the operator's skill and sense of responsibility, resulting in low overall processing efficiency.

[0004] Manual clamping methods struggle to guarantee consistent and uniform clamping force each time. Excessive clamping force can deform the thin-walled reducer housing, affecting machining accuracy; while insufficient clamping force can cause workpiece displacement or vibration under cutting forces, similarly reducing machining quality and even leading to safety accidents. Therefore, achieving rapid, stable, and controllable automated clamping of the main reducer housing has become a pressing technical problem to be solved in this field.

[0005] Therefore, this utility model proposes an end face turning fixture for the main reducer housing to overcome the shortcomings of the prior art. Utility Model Content

[0026] 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.

[0027] Reference Figures 1-4 The present invention provides an embodiment of a main reducer housing end face turning fixture, which aims to solve the problems of low automation of clamping devices and difficulty in cleaning up processing waste in the prior art.

[0028] The end face turning fixture of the main reducer housing includes a support assembly 1. The support assembly 1 includes a support plate 101 as the mounting base, a bottom plate 102 fixedly connected to the support plate 101, and a top plate 103 spaced above the bottom plate 102. The support plate 101, the bottom plate 102 and the top plate 103 together constitute a stable support frame for the fixture.

[0029] The clamp also includes a fixing component 2 and a pull-out component 3 mounted on the support frame;

[0030] The fixing component 2 is used to automatically clamp the reducer housing to be processed. The fixing component 2 includes a motor 201 fixedly connected to the top plate 103, a gear 205 that is linked to the motor 201 and rotated on the top plate 103, and the output shaft of the motor 201 is drivenly connected to the gear 205. The fixing component 2 also includes a slide plate 202 horizontally set on the top plate 103, and two sliders 203 that are slidably connected to the slide plate 202 respectively. Each slider 203 is fixedly connected to a rack 204 and a clamping block 206. The two racks 204 are located on both sides of the gear 205 and mesh with the gear 205. When the motor 201 drives the gear 205 to rotate, the gear 205 can drive the two racks 204 and the sliders 203 and clamping blocks 206 fixedly connected to the racks 204 to move synchronously towards or away from each other through meshing transmission, thereby realizing the automatic clamping or release of the reducer housing.

[0031] The pull-out assembly 3 is used to collect and clean up processing waste. The pull-out assembly 3 includes a waste storage box 301. A sliding groove 304 is provided on the base plate 102 for the waste storage box 301 to slide in. The waste storage box 301 can slide back and forth in the sliding groove 304, which facilitates subsequent waste cleaning operations.

[0032] Both the motor 201 and the slide plate 202 are fixedly connected to the top plate 103. The slide plate 202 has a dovetail groove structure, and two sliders 203 are slidably connected on the slide plate 202. Each slider 203 is a dovetail block structure that cooperates with the dovetail groove structure. The stability of the movement of the slider 203 is ensured by the dovetail sliding cooperation.

[0033] Gear 205 is rotatably mounted on top plate 103 and located between two sliders 203. Motor 201 is coaxially mounted with gear 205. Racks 204 are fixedly connected to the opposite sides of the two sliders 203 respectively, and clamps 206 are fixedly connected to the outer sides of the two sliders 203 respectively. Both racks 204 mesh with gear 205. Through this symmetrical gear and rack transmission structure, when motor 201 drives gear 205 to rotate, it can accurately drive the two sliders 203 carrying clamps 206 to move synchronously towards or away from each other.

[0034] The specific internal structure of the drive motor 201 can be implemented by a variety of conventional methods such as stepper motors or servo motors by those skilled in the art, which are well known in the field and will not be described in detail here.

[0035] The pull-out assembly 3 also includes a rotating latch 302 rotatably disposed on the base plate 102. The end of the rotating latch 302 can selectively extend into or out of the internal space of the waste storage box 301. When the end of the rotating latch 302 extends into the waste storage box 301, it can restrict the sliding of the waste storage box 301, thereby achieving locking.

[0036] The pull-out assembly 3 also includes a connecting post 305 fixedly connected to the base plate 102, and a rotating block 302 is connected to the connecting post 305 by rotation, providing a stable rotation axis;

[0037] In order to enable the waste storage box 301 to pop out automatically, the pull-out assembly 3 also includes a spring 306. One end of the spring 306 abuts against the inner wall of the bottom of the sliding groove 304, and the other end abuts against the inner wall of the waste storage box 301. The spring 306 always applies an outward elastic force to the waste storage box 301.

[0038] To prevent the waste storage box 301 from completely detaching when it pops out, the pull-out assembly 3 also includes a baffle 303 fixedly connected to the base plate 102. The baffle 303 is set at the opening of the sliding groove 304 and located on the sliding path of the waste storage box 301, which limits the movement of the popped-out waste storage box 301.

[0039] Working principle: When clamping the workpiece, the main reducer housing is placed between the two clamping blocks 206. The motor 201 fixed to the top plate 103 is started. The motor 201 drives the gear 205 coaxial with the motor to rotate. Since the gear 205 meshes with the two racks 204 at the same time, the rotation of the gear 205 will drive the two racks 204 and the slider 203 fixedly connected to the racks 204 to slide towards each other on the slide plate 202. The slider 203 drives the clamping blocks 206 to clamp the reducer housing synchronously. After the clamping action is completed, the turning process can begin.

[0040] During the turning process, the cutting waste generated will fall into the waste storage box 301 below. At this time, the end of the rotating block 302 is locked inside the waste storage box 301. After the machining is completed, when it is necessary to clean the waste, drive the rotating block 302 to rotate on the connecting column 305, so that the end of the rotating block 302 is disengaged from the waste storage box 301. After the lock is released, under the elastic thrust of the spring 306, the waste storage box 301 will automatically pop out along the sliding groove 304 until it is blocked by the baffle 303 and stops. The operator can then easily take out the waste storage box 301 for cleaning. After cleaning, push the waste storage box 301 back into the sliding groove 304 and rotate the rotating block 302 in the opposite direction to lock it again, waiting for the next work cycle.

[0041] When it is necessary to release the workpiece, the motor 201 is started in reverse, and the gear 205 drives the two racks 204 and the slider 203 to move in opposite directions, so that the clamp 206 releases the reducer housing and the workpiece can be removed.
