Description

Technical Field

[0001] This utility model relates to the field of milling fixture technology, specifically to a milling fixture for an electric motor base. Background Technology

[0002] An electric motor consists of an outer casing and a rotor that rotates within the casing via bearings. Electric motors used in industrial environments are relatively large and require a motor mount for mounting on equipment.

[0003] Most motors use a cylindrical frame. During production, the inner circle, end stops, and flat surfaces of the cylindrical frame need to be machined. The inner circle and end stops must be coaxial, and the runout of the end face must be small to ensure the installation quality and mechanical and electrical performance of the motor.

[0004] However, existing milling fixtures for motor housings cannot adjust the machining angle of the housing during machining, requiring multiple clamping operations to complete the milling process. This results in high workload for machining workers and low machining efficiency. Summary of the Invention

[0005] To address the aforementioned shortcomings in the existing technology, this utility model provides a milling fixture for motor bases, which solves the problems of existing milling fixtures being unable to adjust the machining angle of the base during machining, requiring multiple clamping operations to complete the milling process of the motor base, resulting in high workload for machining workers and low machining efficiency.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A milling fixture for an electric motor base includes a bridge plate, on the bottom surface of which a plurality of clamping cylinders are uniformly fixedly mounted in a circular array. The output end of each clamping cylinder passes through the bridge plate and is fixedly connected to a connecting rod, the top of which is fixedly connected to a pressure block. A drive mechanism is also included, with its output end fixedly connected to one side of the bridge plate. A support base is also included, with its side rotatably connected to the side of the bridge plate away from the drive mechanism. The drive mechanism is capable of driving the bridge plate to rotate. The end face of the support base faces the output end of the drive mechanism, and equal-height blocks are fixedly mounted on the top surface of the bridge plate at positions corresponding to the pressure blocks.

[0007] In this way, the motor base is placed on the equal height block on the top surface of the bridge plate, the clamping cylinder is activated, and the connecting rod and the pressure block are driven to descend. After descending a certain distance, the pressure block abuts against the motor base, limiting the motor base. After fixing the motor base, start the drive mechanism to rotate the bridge plate. Specifically, the bridge plate rotates around the axis between the drive mechanism and the support base, adjusting the tilt angle of the bridge plate and the motor base. After processing is completed, start the drive mechanism again to reset it, and then start the clamping cylinder again to release the limit on the motor base. With this structure, the processing angle of the motor base can be adjusted, and multiple angles can be processed in one clamping, reducing the number of clamping operations, thereby improving processing efficiency and reducing the workload of workers.

[0008] Furthermore, multiple floating support columns are uniformly fixedly installed in a circular array on the top surface of the bridge plate, thereby assisting the equal-height blocks in supporting the motor base.

[0009] Furthermore, the floating support column includes a plurality of fixed columns that are uniformly fixedly installed on the top surface of the bridge plate in a circumferential array. The top surface of the fixed column has a floating groove, and a support column is provided in the floating groove. The support column and the bottom surface of the floating groove are fixedly connected by an elastic element.

[0010] In this way, when the motor base is placed, the motor base presses down on the support column, and the support column descends along the floating groove. During the descent, the support column squeezes the elastic element, and the elastic element undergoes elastic deformation, absorbing the energy of the impact of the motor base descending, and assisting the equal-height blocks to jointly support the motor base. After the motor base is machined, the limiting mechanism on the motor base is released, the motor base is taken out, and the elastic element elastically resets, pushing the support column to rise and reset. This structure can assist the equal-height block in supporting the motor base, reducing the possibility of collision damage between the motor base and the equal-height block.

[0011] Furthermore, multiple positioning posts are uniformly fixedly installed in a circular array on the top surface of the bridge plate, which can position the motor base, reduce the possibility of motor base misalignment, and thus improve machining accuracy.

[0012] Furthermore, the connecting rod and the pressure block are fixedly connected by a threaded rod, thereby allowing the angle of the pressure block to be changed according to the actual working conditions, ensuring that the pressure block plays a limiting role on the motor base.

[0013] Furthermore, the top surface of the pressure block has a threaded groove, which allows the pressure block to be connected to an external limiting component under actual working conditions, thereby improving the applicability of this fixture.

[0014] Furthermore, a baffle is symmetrically and fixedly installed on the top surface of the bridge plate, which can protect the drive mechanism and reduce the possibility of processing debris entering the drive mechanism.

[0015] Furthermore, the drive mechanism adopts a direct drive motor, which can improve positioning accuracy and thus improve the machining accuracy of the motor base. Attached Figure Description

Detailed Implementation

[0017] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0018] The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual images. They should not be construed as limiting the scope of this patent. To better illustrate the embodiments of this utility model, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0019] Example: like Figures 1-6As shown, this utility model discloses a milling fixture for an electric motor base, comprising a bridge plate 1, on which a plurality of clamping cylinders 101 are uniformly fixedly mounted in a circular array on the bottom surface of the bridge plate 1. The output end of the clamping cylinders 101 passes through the bridge plate 1 and is fixedly connected to a connecting rod 102, and a pressure block 103 is fixedly connected to the top of the connecting rod 102; a drive mechanism 2, the output end of which is fixedly connected to one side of the bridge plate 1; and a support base 3, the side of which is rotatably connected to the side of the bridge plate 1 away from the drive mechanism 2. The drive mechanism 2 can drive the bridge plate 1 to rotate. The end face of the support base 3 is set facing the output end of the drive mechanism 2. Equal height blocks 104 are fixedly mounted on the top surface of the bridge plate 1 at positions corresponding to the pressure blocks 102.

[0020] In this way, the motor base is placed on the equal height block 104 on the top surface of the bridge plate 1, the clamping cylinder 101 is activated, and the connecting rod 102 and the pressure block 103 are driven to descend. After descending a certain distance, the pressure block 103 abuts against the motor base to limit the motor base. After fixing the motor base, start the drive mechanism 2 to rotate the bridge plate 1. Specifically, the bridge plate 1 rotates around the axis between the drive mechanism 2 and the support base 3 to adjust the tilt angle of the bridge plate 1 and the motor base. After processing is completed, start the drive mechanism 2 again to reset it, and start the clamping cylinder 101 again to release the limit on the motor base. With this structure, the processing angle of the motor base can be adjusted, and multiple angles can be processed in one clamping, reducing the number of clamping times, thereby improving processing efficiency and reducing the workload of workers.

[0021] Multiple floating support columns 4 are evenly fixedly installed in a circular array on the top surface of the bridge plate 1, which can assist the equal height block 104 in supporting the motor base.

[0022] The floating support column 4 includes multiple fixed columns 401 that are uniformly fixedly installed on the top surface of the bridge plate 1 in a circular array. The top surface of the fixed column 401 has a floating groove 402. The support column 403 is provided in the floating groove 402. The support column 403 and the bottom surface of the floating groove 402 are fixedly connected by an elastic element 404.

[0023] In this way, when the motor base is placed, the motor base presses down on the support column 403, and the support column 403 descends along the floating groove 402. During the descent, the support column 403 squeezes the elastic element 404, and the elastic element 404 undergoes elastic deformation, absorbing the energy of the impact of the motor base descending, and assisting the equal height block 104 to jointly support the motor base. After the motor base is processed, the limit on the motor base is released and the motor base is taken out. The elastic element 404 elastically resets, pushing the support column 403 to rise and reset. With this structure, the leveling block 104 can assist in supporting the motor base and reduce the possibility of collision damage between the motor base and the leveling block 104.

[0024] Multiple positioning posts 5 are evenly fixedly installed in a circular array on the top surface of the bridge plate 1, which can position the motor base, reduce the possibility of motor base misalignment, and thus improve machining accuracy.

[0025] The connecting rod 102 and the pressure block 103 are fixedly connected by a threaded rod 105, which allows the angle of the pressure block 103 to be changed according to the actual working conditions, ensuring that the pressure block 103 plays a limiting role on the motor base.

[0026] The top surface of the pressure block 103 has a threaded groove 106, which allows the pressure block 103 to be connected to an external limiting component under actual working conditions, thereby improving the applicability of this fixture.

[0027] A baffle 6 is symmetrically fixedly installed on the top surface of the bridge plate 1, which can protect the drive mechanism 2 and reduce the possibility of processing debris entering the drive mechanism 2.

[0028] The drive mechanism 2 uses a direct drive motor, which improves positioning accuracy and thus improves the machining accuracy of the motor base.

Some typical known structures or methods should not be obstacles for those skilled in the art to implement this application. It should be noted that those skilled in the art can make several modifications and improvements without departing from the structure of this utility model.
