[0002] The gearbox is a core component in automobile manufacturing. It is mainly used to change the transmission ratio, enable the car to travel backwards without changing the direction of engine rotation, utilize neutral gear, interrupt power transmission, and enable the engine to start, idle, shift gears or output power. The quality of the gearbox also affects the quality of the car. The gearbox housing carries the gear structure, so the quality of the housing is also crucial. The quality of the gearbox housing directly affects the performance of the gears, and affects the vibration, noise, efficiency and life of the entire machine.

[0003] However, there are some problems with the prior art: after the gearbox housing is initially formed, it is necessary to perform punching processing at the corresponding position on the surface of the gearbox housing. In order to ensure the stability of the punching processing, a clamp is usually used to limit and clamp the housing to ensure that the housing will not be far away during punching. However, the gearbox housing is large in size, and multiple clamping devices are required in the process of clamping and limiting it. During the punching process, debris from the shell processing process is likely to accumulate at the clamping position. During the clamping and limiting process of the next shell, these debris are likely to cause the shell to shift during the clamping process, so that the punched shell cannot meet the quality requirements required for production, causing the gearbox housing to be scrapped and affecting production efficiency. Therefore, we propose a clamp for processing the gearbox motor housing. Utility Model Content

[0021] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention unless otherwise specifically stated.

[0022] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses.

[0023] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0024] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0025] The structure of the utility model is described in detail below in conjunction with the accompanying drawings.

[0026] like Figures 1 to 4As shown, a gearbox motor housing processing fixture provided by an embodiment of the utility model comprises a base 1, a fixture table 2 is arranged at one end of the upper surface of the base 1, and a material guide hole 3 is opened on one side of the fixture table 2. During the punching process of the gearbox housing, there will be downward pressure. During multiple punchings, one end of the gearbox housing will rub against the fixture table 2 for multiple times, which will cause wear on the lower end of the gearbox housing. The material guide hole 3 is opened on one side of the fixture table 2 so that during the punching process of the gearbox housing, one end of the gearbox housing will not contact the fixture table 2, so that the gearbox punching process will not be affected by pressure, causing wear on one end of the gearbox housing. The size of the material guide hole 3 is adapted to the shape of the gearbox housing. A supporting component 4 and multiple groups of clamping components 5 are arranged on one side of the fixture table 2. The multiple groups of clamping components 5 are respectively located at the edges of the material guide hole 3. A positioning block 7 is arranged on one side of the clamping component 5. Four groups of clamping components 5 are arranged. The four groups of clamping components 5 are arranged in four different positions to clamp and fix the edges of the gearbox housing respectively. The positioning blocks 7 are arranged corresponding to the positioning holes reserved on the gearbox housing. The gearbox housing is arranged so that the gearbox housing is accurately placed on the positioning block 7 and fixedly clamped by the clamping assembly 5. The supporting assembly 4 is arranged at the lower end of one side of the fixture table 2 to support the gearbox housing, relieve the force of the clamping assembly 5 on the gearbox housing, and prevent the gearbox housing from falling due to its own weight. A cleaning assembly 6 is arranged on one side of the fixture table 2. During the punching process of the gearbox housing, the debris generated by the shell processing is easily accumulated at the fixed support of the clamping assembly 5 and the supporting assembly 4. During the clamping and limiting process of the next gearbox housing, these debris are easy to cause the gearbox housing to deviate during the clamping process, so that the punched housing cannot meet the quality requirements required for production, causing the gearbox housing to be scrapped and affecting production efficiency. Therefore, a cleaning assembly 6 is arranged to flush the clamping assembly 5 and the supporting assembly 4 to flush the debris attached thereto. When processing another gearbox housing, the gearbox housing clamping limit will not be offset due to the influence of the debris, thereby causing the gearbox housing to be damaged, thereby affecting the production of the gearbox housing.

[0027] The clamping assembly 5 includes a second cylinder 501, which is arranged on one side of the clamping table 2. A base 502 is arranged at one end of the second cylinder 501, and an extending end of the second cylinder 501 passes through the base 502. A pressure block 503 is rotatably connected to the extending end of the second cylinder 501. Auxiliary rods 504 are rotatably connected to both sides of the pressure block 503. One end of two sets of auxiliary rods 504 is rotatably connected to one end of the base 502, and extends outward through the extending end of the second cylinder 501 to rotate one end of the pressure block 503. At the same time, the two sets of auxiliary rods 504 assist in cooperating with the pressure block 503, so that the other end of the pressure block 503 presses the edge of the gearbox housing to fix the gearbox housing.

[0028] Two sets of auxiliary clamping components 8 are arranged on one side of the clamping table 2. The auxiliary clamping components 8 include a bottom block 801, which is arranged on one side of the clamping table 2. A groove 9 is provided on one side of the bottom block 801. A stop block 802 is rotatably connected in the groove 9. One side of the stop block 802 is arranged in a trapezoidal shape. A placement block 803 is provided at one end of the bottom block 801. A through hole is provided on one side of the placement block 803. A bolt 804 is threadedly connected to one side of the stop block 802. One end of the bolt 804 passes through the through hole. A baffle 805 and a spring 806 are sleeved on the surface of the bolt 804. 06, the baffle 805 and the spring 806 are located between the stop block 802 and the placement block 803. During the placement of the gearbox housing, the edge of the gearbox housing abuts against the inclined surface of the stop block 802, causing the stop block 802 to tilt toward the placement block 803. At the same time, the spring 806 is compressed under the extrusion of the stop block 802, and the bolt 804 moves in the through hole. When the gearbox housing contacts the positioning block 7, the stop block 802 rebounds under the action of the spring 806, causing the stop block 802 to fix the edge of the gearbox housing.

[0029] The support assembly 4 includes three groups of support platforms 401. The three groups of support platforms 401 are arranged on one side of the fixture platform 2 and are arranged in a triangular shape to support the lower half of the gearbox housing and limit it at the same time.

[0030] The support assembly 4 also includes three groups of support rods 402, and the three groups of support rods 402 are arranged in a triangular shape, wherein two groups of support rods 402 are arranged on one side of the fixture table 2, and the other group of support rods 402 is arranged on the upper surface of the base 1, and two groups of first oil cylinders 403 are arranged on one side of the support rods 402, and a protective platform 404 corresponding to the first oil cylinder 403 is arranged on one side of the support rods 402, and the protective platform 404 is used to protect the first oil cylinder 403 to prevent the first oil cylinder 403 from colliding with the first oil cylinder 403 during the movement of the gearbox housing, thereby causing damage to the first oil cylinder 403.

[0031] The cleaning component 6 includes a water pipe 601, on the surface of which a fixed block 602 is fixedly installed. The fixed block 602 is fixedly installed on one side of the fixture table 2. The surface of the water pipe 601 is provided with multiple groups of water spray heads 603, which are staggered and inclined. The staggered and inclined arrangement of the water spray heads 603 allows the water spray heads 603 to cross-spray the clamping component 5 and the supporting component 4, so that the debris on the clamping component 5 and the supporting component 4 is washed with water at a certain angle, which facilitates the debris to be washed away by water. At the same time, the base 1 is arranged in an inclined surface, which facilitates the water flow to cause the debris to flow away from the upper surface of the base 1 under the drive of the inclined surface.
