Description

Technical Field

[0001] The utility model relates to the technical field of motor processing, and more specifically, to a processing fixture for a motor housing. Background Art

[0002] Currently, the motor housings on the market are usually treated with high-gloss black paint to give them good visual effects. However, when machining the motor housing, since machining needs to be performed at most positions of the entire housing, special fixtures must be used to firmly fix the motor housing on the workbench of the machining machine tool.

[0003] However, the existing fixtures are fixed by clamping the housing, but this method has various problems. First, it is rather cumbersome to install the motor housing into the existing fixture, and the clamping process takes a long time, affecting production efficiency. Second, since the fixture uses a clamping method, the high-gloss black paint surface of the housing is easily damaged, which not only affects the appearance but also may reduce the overall quality of the product. In addition, the existing clamping fixtures usually require a large installation space, which has high requirements for the space of the processing machine tool. In the actual processing environment, the installation space of the machine tool is often limited, which further restricts the application scope of the existing fixtures.

[0004] Therefore, at the present stage, during the fixing process of the motor housing, there are problems such as complex operation, easy damage to the housing, and low space utilization rate. In view of this, this application is specifically proposed. Summary of the Utility Model

[0005] In view of this, the purpose of the utility model is to provide a processing fixture for a motor housing to solve the above problems.

[0006] The utility model adopts the following scheme:

[0007] This application provides a processing fixture for a motor housing, including a fixture template; a plurality of mounting grooves arranged at intervals horizontally and vertically are provided on the upper surface of the fixture template; the mounting grooves are all configured as profiling grooves matching the shape of the motor housing, and an air channel is provided on the mounting groove, and the air channel is recessed on the upper surface of the mounting groove; the air channels between adjacent mounting grooves spaced longitudinally are connected and communicated with each other to form the same air path, and an air inlet groove communicating with the air path is provided on the fixture template, and the air inlet groove is used for externally connecting a vacuum pumping pipe.

[0008] As a further improvement, the air inlet groove extends on one side of the air path for communicating the mounting groove with the outside.

[0009] As a further improvement, at least six of the mounting grooves are provided at intervals in the transverse direction, at least three of the mounting grooves are provided at intervals in the longitudinal direction, and the number of the air inlet grooves is equal to the number of the mounting grooves arranged horizontally.

[0010] As a further improvement, the air inlet grooves are externally connected to their respective vacuum extraction pipes, and the vacuum extraction pipes are arranged in parallel with each other to communicate with the same vacuum pump.

[0011] As a further improvement, the distance between the mounting grooves arranged at intervals in the transverse direction is smaller than the distance between the mounting grooves arranged at intervals in the longitudinal direction.

[0012] As a further improvement, after the mounting grooves are adaptively butted with the motor housing, the internal space of the profiling groove is communicated with the air path to generate negative pressure after vacuum extraction operation, so as to firmly limit the motor housing on the fixture template.

[0013] As a further improvement, the air path penetrates through the longitudinally arranged mounting grooves in the middle, and different air paths are longitudinally arranged and do not interfere with each other.

[0014] As a further improvement, the fixture template is made of steel and has a thin plate-like structure.

[0015] By adopting the above technical solutions, the following technical effects can be achieved by the present utility model:

[0016] 1. For the processing fixture for the motor housing of the present application, a profiling groove matching the shape of the motor housing is adopted to ensure that the housing can be accurately embedded in the fixture template, improving the fixing stability. The profiling groove makes the housing not prone to displacement during the processing, ensuring the accuracy of subsequent processing.

[0017] 2. By arranging an air duct on the profiling groove and communicating it with the air path, the motor housing is firmly fixed on the fixture by means of vacuum extraction, so that mechanical clamping is not required, thus effectively avoiding scratches or indentations on the high-gloss black painted surface of the motor housing and maintaining the appearance quality of the housing.

[0018] 3. Since the fixation of the fixture depends on the air path system, the rapid clamping and disassembling of the housing can be realized with simple operation, greatly shortening the clamping time, improving the processing efficiency, simplifying the operation process at the same time, reducing the human operation error, and the air ducts exposed on the surface of the mounting grooves have a relatively small occupied space and a more streamlined and efficient air path layout through the integrated design and reasonable air path layout, can adapt to the limited machine installation space in the processing environment, improving the space utilization rate of the equipment. At the same time, the air ducts between adjacent mounting grooves in the longitudinal direction are connected and penetrated with each other, reducing the need for complex pipeline layout and making the whole system more compact.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts fall within the scope of protection of the present utility model. Therefore, the following detailed description of the embodiments of the present utility model provided in the drawings is not intended to limit the scope of the present utility model claimed, but merely represents selected embodiments of the present utility model.

[0026] Embodiment

[0027] Combined with Figures 1 to 4 , this embodiment provides a processing fixture for a motor housing, including a fixture template 1. A plurality of horizontally and vertically spaced installation grooves 2 are provided on the upper surface of the fixture template 1. The installation grooves 2 are all configured as profiling grooves matching the shape of the motor housing, and an air duct 3 is formed on the installation groove 2. The air duct 3 is recessed on the upper surface of the installation groove 2. The air ducts 3 between adjacent installation grooves 2 spaced longitudinally are connected and communicated with each other to form the same air path. An air inlet groove 4 communicating with the air path is provided on the fixture template 1, and the air inlet groove 4 is used for externally connecting a vacuum suction pipe (not shown in the figure).

[0028] For the above-mentioned processing fixture for the motor housing, profiling grooves matching the shape of the motor housing are adopted to ensure that the housing can be accurately embedded in the fixture template 1, improving the fixing stability. The profiling grooves prevent the housing from being displaced during the processing, ensuring the accuracy of subsequent processing.

[0029] By providing an air passage 3 on the profiling groove and connecting it to the air circuit, the motor housing is firmly fixed to the fixture by means of vacuum pumping, thus eliminating the need for mechanical clamping. Therefore, scratches or indentations on the highly polished black painted surface of the motor housing are effectively avoided, maintaining the appearance quality of the housing.

[0030] Since the fixation of the fixture depends on the air circuit system, the quick clamping and unclamping of the housing can be achieved with simple operations, greatly shortening the clamping time, improving the processing efficiency, simplifying the operation process, reducing human operation errors, and the air passage 3 exposed on the surface of the mounting groove 2 occupies relatively less space and the air circuit layout is more streamlined and efficient through integrated design and reasonable layout of the air passage 3, which can adapt to the limited machine installation space in the processing environment, improving the space utilization rate of the equipment. At the same time, the air passages 3 between adjacent mounting grooves 2 in the longitudinal direction are interconnected and communicated, reducing the need for complex pipeline arrangements and making the whole system more compact.

[0031] As Figures 2 to 4 shown, in this embodiment, the intake groove 4 extends on one side of the air circuit for connecting the mounting groove 2 to the outside. Specifically, the intake groove 4 is opened on the surface of the processing fixture on the side close to the user. By extending the intake groove 4 to the air circuit, the intake groove 4 can directly connect the mounting groove 2 to the outside, making the layout of the air circuit more concise and clear, reducing the complexity of the air circuit arrangement, and helping to reduce the manufacturing and maintenance costs.

[0032] Preferably, at least six of the mounting grooves 2 are provided at intervals in the transverse direction, at least three of the mounting grooves 2 are provided at intervals in the longitudinal direction, and the number of the intake grooves 4 is equal to the number of the mounting grooves 2 arranged in the transverse direction. Thus, the fixture can fix multiple motor housings simultaneously, adapt to the processing requirements of different specifications and sizes, be widely applied to different processing tasks, and significantly improve the flexibility and adaptability of the production line.

[0033] Among them, the intake groove 4 is externally connected to respective vacuum pumping pipes, and the vacuum pumping pipes are arranged in parallel with each other and connected to the same vacuum pump. The vacuum pumping pipes are connected in parallel to the same vacuum pump to ensure that each mounting groove 2 can obtain a uniform and stable vacuum pumping effect. Even if one of the pipelines has a problem, the other pipelines can still work normally, ensuring the stability and reliability of the entire fixture system. Obviously, the vacuum pump connects the vacuum pumping pipes to the air circuit to achieve the purpose of vacuum pumping, which belongs to the prior art and will not be described in detail here.

[0034] Furthermore, the spacing between the mounting grooves 2 arranged at intervals in the transverse direction is smaller than the spacing between the mounting grooves 2 arranged at intervals in the longitudinal direction. By reducing the spacing between the transverse mounting grooves 2, the motor housings can be arranged more compactly, enabling the jig to accommodate more processing objects in a limited space. And increasing the longitudinal spacing makes the connection between adjacent air ducts 3 more effective and reliable, contributing to improving the reliability and stability of the air path connection.

[0035] It can be understood that after the motor housing is adaptively docked with the mounting groove 2, the internal space of its profiling groove is connected to the air path to generate negative pressure after the vacuum pumping operation, so as to firmly limit the motor housing on the jig template 1. Among them, the internal space of the profiling groove is connected to the air path, and the negative pressure generated after vacuum pumping can act evenly on the surface of the motor housing, firmly adsorbing it on the jig template 1. Thus, compared with the traditional mechanical clamping method, the negative pressure fixation is more uniform and stable, effectively avoiding the displacement or loosening of the housing during the processing, thereby ensuring the processing accuracy.

[0036] In this embodiment, the air path runs through the longitudinally arranged mounting grooves 2 in the middle, and different air paths are arranged longitudinally and do not interfere with each other. Running the air path through the longitudinally arranged mounting grooves 2 in the middle can ensure that each mounting groove 2 can obtain a uniform air flow distribution, and the uniform negative pressure acts on each motor housing, making its fixation more stable, and avoiding problems such as the displacement or insecure fixation of the housing caused by uneven air flow distribution. In addition, different air paths are arranged longitudinally and do not interfere with each other, enabling each air path to operate independently in the system without affecting the use of the overall jig, greatly improving the reliability and stability of the system.

[0037] In this embodiment, the jig template 1 is made of steel and has a thin plate-like structure. The steel material has high strength and good wear resistance, enabling the jig template 1 to maintain good performance and shape stability during long-term use. Due to the high rigidity of the steel material, the thin plate-like jig template 1 can provide sufficient support force and stability while maintaining a light structure, helping to maintain the precise positioning of the motor housing during processing and ensuring that the processing accuracy is not affected.

[0038] The above is only the preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention.
