Description

Technical Field

[0001] This utility model relates to the technical field of motor bracket grinding equipment, specifically a motor bracket edge grinding device. Background Technology

[0002] A motor bracket is a mechanical structural component used to fix and support a motor (electric motor). It is usually designed with a specific shape (such as L-shape, flat plate, etc.) according to the motor model, installation scenario and stress requirements. The material is mostly metal (such as cast iron, aluminum alloy) or high-strength engineering plastic. Its core function is to stably install the motor in the designated position of the equipment (such as automobiles, machine tools, robots, etc.), reduce the transmission of vibration during motor operation, ensure the coaxiality or relative position accuracy of the motor and related components (such as drive shafts, gears), and provide heat dissipation assistance and protective support for the motor. It is a key supporting component to ensure the safe and stable operation of the motor.

[0003] A search revealed that Chinese patent application number CN202323511099.5 discloses an edge grinding device for motor bracket production, comprising: a grinding table, a clamping assembly disposed at the top center of the grinding table, support blocks disposed on both sides of the clamping assembly, a lead screw inserted into the support block, and one end of the lead screw connected to a clamping plate; an annular groove is formed around the clamping assembly, and a debris box is placed in the annular groove.

[0004] The above-mentioned technical solutions and traditional motor grinding equipment still have defects. For example, they cannot be well adapted to L-shaped motor brackets. The vertical corners of the L-shaped support plate can easily block the grinding tools, resulting in some hole walls not being effectively ground. Moreover, most existing grinding equipment is general-purpose and is not specifically designed for the structural characteristics of L-shaped motor support plates and the grinding requirements of round holes. It is difficult to effectively fix and position the L-shaped support plate during the grinding process, resulting in poor grinding effect.

[0005] Therefore, we need to propose a motor bracket edge grinding device. Utility Model Content

[0006] The purpose of this utility model is to provide a motor bracket edge grinding device that can perfectly fit an L-shaped motor bracket, effectively solving the problem that traditional grinding equipment cannot fit an L-shaped motor bracket well, ensuring that the bracket can be stably fitted during the grinding process, providing a foundation for high-quality grinding, and solving the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: A motor bracket edge grinding device, comprising: Two sets of support plates, each set of support plates having a base platform at its upper end, and the base platform having an opening; A grinding mechanism is provided above the base. The grinding mechanism includes a motor and a grinding wheel. A ferrule is provided on the upper end of the grinding wheel. The shaft and the motor output shaft are fixed together by a coupling. A fixing mechanism is provided on the support plate. The fixing mechanism includes a clamping plate and a clamping block. The clamping block is located on one side of the clamping plate. The clamping plate is driven by a cylinder. The clamping block is an inverted L-shaped rubber block.

[0008] Preferably, the clamping block has a clamping groove with a V-shaped cross-section to accommodate an L-shaped motor bracket.

[0009] Preferably, a cylinder is installed on the outer wall of the support plate, the piston rod end of the cylinder passes through the support plate and is connected to a telescopic plate, the clamping plate is locked together with the telescopic plate by a nut, and the cylinder drives the telescopic plate so that the clamping blocks on the two sets of clamping plates clamp and fix the L-shaped motor.

[0010] Preferably, the outer wall of the clamping plate is symmetrically provided with studs, and the telescopic plate is provided with through holes for the studs to pass through. When the clamping plate and the telescopic plate are fixed, the two are fitted together and the studs are locked by nuts after passing through the through holes.

[0011] Preferably, it also includes a rotating mechanism disposed on the base. The rotating mechanism includes a U-shaped frame and a shaft. The shaft is rotatably mounted on the U-shaped frame. The shaft and the notch are coaxially arranged. A rocker arm is provided at the upper end of the shaft, and a rotating arm is provided at the lower end of the shaft.

[0012] Preferably, the rotating arm is L-shaped, and an electric push rod is installed on the rotating arm. The telescopic rod of the electric push rod passes through the vertical arm of the rotating arm and is connected to an L-shaped fixing plate at its end. The motor is installed on the horizontal arm of the fixing plate. The rotating arm can drive the grinding mechanism to rotate. The grinding radius can be adjusted by the electric push rod to fit the edge of the round hole of the L-shaped motor bracket.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. The clamping block adopts an inverted L-shaped rubber block, and the clamping groove has a V-shaped cross section. This unique design can perfectly fit the L-shaped motor bracket, effectively solving the problem that traditional grinding equipment cannot fit the L-shaped motor bracket well, ensuring that the bracket can be stably fitted during the grinding process, and providing a foundation for high-quality grinding.

[0014] 2. By setting up a rotating mechanism, the rotating arm is L-shaped and equipped with an electric push rod. The rotating arm can drive the grinding mechanism to rotate, and the electric push rod can adjust the grinding radius. This design cleverly solves the problem that the grinding tools are easily blocked at the vertical corner of the L-shaped support plate, resulting in some hole walls not being effectively ground. It can achieve all-round, dead-angle-free grinding of the edge of the round hole of the L-shaped motor bracket, significantly improving the grinding effect. Attached Figure Description

[0017] 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.

[0018] Please see Figure 1-3 This utility model provides a technical solution: A motor bracket edge grinding device, comprising: Two sets of support plates 1, with a base 2 at the upper end of the two sets of support plates 1, and an opening on the base 2; Two sets of support plates 1 serve as the basic support structure for the entire device, providing a stable mounting platform for other components above. The base 2 is located on the upper end of the support plate 1, and the notch on it provides space for the installation and movement of subsequent grinding mechanisms and other related components. It may also be related to the shape of the L-shaped motor bracket, facilitating the placement of the bracket and grinding operations. It forms the overall frame of the device, providing installation positions for various functional components. It is the basic load-bearing structure of the entire grinding device, ensuring the stability of the device and the relative positional relationship between the components.

[0019] Please see Figure 1-2 : A fixing mechanism, mounted on the support plate 1, includes a clamping plate 14 and a clamping block 15. The clamping block 15 is located on one side of the clamping plate 14 and is driven by a cylinder 12. The clamping block 15 is an inverted L-shaped rubber block. A clamping groove is formed on the clamping block 15, with a V-shaped cross-section to accommodate the L-shaped motor bracket. A cylinder 12 is mounted on the outer wall of the support plate 1. The piston rod end of the cylinder 12 passes through the support plate 1 and is connected to a telescopic plate 13. The clamping plate 14 is locked together with the telescopic plate 13 by a nut. The cylinder 12 drives the telescopic plate 13, causing the clamping blocks 15 on the two sets of clamping plates 14 to clamp and fix the L-shaped motor.

[0020] Cylinder 12 is mounted on the outer wall of support plate 1. The extension and retraction of its piston rod drives telescopic plate 13 to move linearly. Since clamping plate 14 is locked together with telescopic plate 13 by nuts, the movement of telescopic plate 13 will cause clamping plate 14 to move synchronously. An inverted L-shaped rubber clamping block 15 is provided on one side of clamping plate 14. The V-shaped clamping groove on clamping block 15 can match the shape of the L-shaped motor bracket. When cylinder 12 drives the two sets of clamping plates 14 to move relative to each other, clamping block 15 will clamp and fix the L-shaped motor bracket. The rubber clamping block 15 can provide a certain amount of cushioning and anti-slip effect during clamping, avoiding damage to the bracket. During clamping, the L-shaped motor bracket is in an inverted L-shape.

[0021] The above technical solution solves the problem of traditional grinding equipment's difficulty in effectively fixing and positioning the L-shaped support plate 1. Through the cylinder 12 drive and the V-shaped clamping groove design, the L-shaped motor bracket can be precisely and stably fixed, ensuring that the bracket will not move or shake during grinding, thereby improving the precision and quality of grinding.

[0022] Please see Figure 1-3 : A grinding mechanism, mounted on the base 2, includes a motor 4 and a grinding wheel 10. A circumferential groove is provided on the upper end of the grinding wheel 10. The shaft 6 and the output shaft of the motor 4 are fixed together by a coupling. Specifically, a rotating mechanism, also mounted on the base 2, includes a U-shaped frame 5 and a shaft 6. The shaft 6 is rotatably mounted on the U-shaped frame 5 and coaxially arranged with a notch 3. A rocker arm 7 is provided at the upper end of the shaft 6, and a rotating arm 8 is provided at the lower end. The rotating arm 8 is L-shaped, and an electric push rod 11 is mounted on it. The telescopic rod of the electric push rod 11 passes through the vertical arm of the rotating arm 8 and its end is connected to an L-shaped fixing plate 9. The motor 4 is mounted on the horizontal arm of the fixing plate 9. Rotating the rocker arm 7 drives the grinding mechanism to rotate, and the electric push rod 11 adjusts the grinding radius to fit the edge of the circular hole in the L-shaped motor bracket.

[0023] After the motor 4 starts, it transmits power to the shaft 6 via a coupling. The shaft 6 drives the grinding wheel 10 to rotate at high speed, thereby achieving the grinding operation on the edge of the motor bracket. The U-shaped frame 5 provides rotational support for the shaft 6, and the shaft 6 and the notch 3 on the base 2 are coaxially arranged. When the operator rotates the rocker arm 7, the shaft 6 will rotate accordingly, thereby driving the lower rotating arm 8 to rotate. Since the motor 4 is mounted on the horizontal arm of the L-shaped fixing plate 9 on the rotating arm 8, the rotation of the rotating arm 8 will drive the entire grinding mechanism to perform a circular motion. The electric push rod 11 is mounted on the rotating arm 8, and the extension and retraction of its telescopic rod can push the L-shaped fixing plate 9 to move in the vertical direction of the rotating arm 8, thereby changing the position of the motor 4 and the grinding wheel 10, and realizing the adjustment of the grinding radius.

[0024] When in use, first retract the electric push rod 11 to reduce the radius. When fixing the motor bracket, the grinding wheel 10 is located in the round hole. Then, the electric push rod 11 extends so that the grinding wheel 10 contacts the edge of the round hole. After locking the grinding radius, start the motor 4 to perform the grinding operation. During the grinding process, rotate the rocker arm 7 to form circumferential grinding.

[0025] In summary, this invention solves the problem that the vertical corner of the L-shaped support plate 1 easily obstructs the grinding tool, resulting in ineffective grinding of some hole walls. By rotating the rocker arm 7, the grinding mechanism can rotate around the shaft 6, thus enabling it to grind the inner edge of the circular hole. The electric push rod 11 adjusts the grinding radius to better fit the shape of the circular hole edge of the L-shaped motor bracket, ensuring comprehensive and uniform grinding of the entire circular hole edge.

[0026] For a preferred implementation, please refer to Figure 3 : Guide rods are symmetrically arranged on the vertical arm of the fixed plate 9. The guide rods are slidably inserted into the vertical arm of the rotating arm 8 to ensure the stability of the fixed plate 9 during the adjustment process.

[0027] When the electric push rod 11 pushes the fixed plate 9 to adjust the grinding radius, the guide rod on the vertical arm of the fixed plate 9 will slide in the vertical arm of the rotating arm 8. The sliding cooperation between the guide rod and the vertical arm of the rotating arm 8 plays a guiding and limiting role, preventing the fixed plate 9 from shifting or shaking during the adjustment process.

[0028] To ensure the stability and accuracy of the electric push rod 11 when adjusting the position of the fixed plate 9, the motor 4 and the grinding wheel 10 can maintain a stable movement during the adjustment process, thereby improving the precision and quality of grinding and avoiding problems such as uneven grinding caused by the instability of the fixed plate 9.

[0029] Among them, the electric actuator 11 uses the model LX600, and its corresponding parameters are: rated power ≤55W, voltage 24V, stroke 30-500mm, speed 5-30mm / s, maximum load force 6000N, and built-in limit switch.

[0030] For a preferred implementation, please refer to Figure 1-2 : The outer wall of the clamping plate 14 is symmetrically provided with studs 16, and the telescopic plate 13 has through holes for the studs 16 to pass through. When the clamping plate 14 and the telescopic plate 13 are fixed, the two are in contact and the studs 16 are locked by nuts after passing through the through holes.

[0031] When installing the clamping plate 14 and the telescopic plate 13, align the stud 16 on the outer wall of the clamping plate 14 with the through hole on the telescopic plate 13, allowing the stud 16 to pass through the through hole. Then, use a nut to lock the other end of the stud 16, thereby firmly fixing the clamping plate 14 and the telescopic plate 13 together. This preferred connection method makes the installation and disassembly of the clamping plate 14 and the telescopic plate 13 more convenient and quick, while also ensuring the connection strength and stability between the two. When it is necessary to replace the clamping plate 14 or maintain the fixing mechanism, the nut can be easily loosened for operation, improving the maintainability and operational flexibility of the device.

[0032] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
