Description

Technical Field

[0001] This utility model relates to the field of grinding equipment technology, and more specifically, to a multi-functional grinding device for metal parts. Background Technology

[0002] Grinding is a crucial step in the processing of metal parts, aiming to remove surface defects, oxide layers, and improve surface finish to meet diverse usage requirements. Currently, various metal parts grinding equipment exists on the market. For example, the integrated grinding machine for metal shaft production disclosed in patent application number CN202411215419.9 achieves grinding of metal shafts by installing a clamping device on the side wall of the machine cover, setting a grinding platform on the surface, and connecting funnel devices. However, existing grinding equipment generally suffers from limited functionality, often only equipped with shaped grinding heads and capable of performing specific types of grinding operations on metal parts. When metal parts require grinding to different shapes or with varying precision, it's often necessary to frequently change the entire grinding equipment or manually replace the grinding heads. This process is not only cumbersome and time-consuming, but frequent equipment or grinding head changes also accelerate equipment wear and tear, reducing its lifespan. Furthermore, it's difficult to guarantee consistent and stable grinding quality, severely impacting production efficiency and product quality. Therefore, developing a device capable of quickly switching between different shaped grinding heads to achieve multi-functional grinding is of significant practical importance. Utility Model Content

[0003] The purpose of this utility model is to provide a multifunctional grinding device for metal parts, so as to solve the problem mentioned in the background art that the existing grinding equipment generally has a relatively single function, and can only be equipped with a grinding head of a certain shape, and can only perform specific types of grinding operations on metal parts.

[0004] To achieve the above objectives, this utility model provides a multifunctional grinding device for metal parts, including a base, a turntable mounted on one side of the base, a plurality of grinding components radially mounted on the side of the turntable, and a drive motor mounted on the top of the base. The turntable rotates to drive different grinding components to connect with the output end of the drive motor, thereby realizing the switching of different grinding components. Different shaped grinding heads are mounted on the grinding components.

[0005] This setup, through the cooperation of a turntable and multiple grinding components, enables rapid switching between grinding heads of different shapes, meeting the diverse grinding needs of metal parts. It eliminates the need for frequent replacement of the entire equipment or manual disassembly of grinding heads, improving processing efficiency and reducing labor costs. At the same time, the multiple grinding heads are adaptable to different processing scenarios, enhancing grinding precision and quality.

[0006] Preferably, the grinding assembly includes a connecting rod, a driving rod is installed at the output end of the drive motor, the end of the driving rod is provided with a socket, one end of the connecting rod is inserted into the socket, and a grinding head is installed at the other end of the connecting rod.

[0007] This design uses a plug-in connection, which makes the connection between the grinding component and the drive motor simple and quick, and the installation and disassembly process is simple. It facilitates the rapid replacement of the grinding component and further improves processing efficiency. At the same time, the plug-in structure ensures effective power transmission and stable operation of the grinding head.

[0008] Preferably, the inner wall of the socket is provided with a limiting groove along the direction of the drive rod, and a slot is provided on one side of the connecting rod. A locking block is provided in the slot, and the locking block engages with the limiting groove.

[0009] The locking mechanism between the locking block and the limiting groove provides a secure fixation for the connection between the grinding components and the drive motor, preventing the grinding components from loosening or falling off during the grinding process and ensuring the stability and safety of the grinding operation.

[0010] Preferably, a positioning ring is installed on the turntable near the connecting rod, and a washer is installed on the inner wall of the positioning ring. Several springs are installed at the bottom of the locking block, and one end of the locking block is provided with an inclined surface. When the grinding component is pulled outward to disengage from the drive rod, the connecting rod moves outward, thereby driving the locking block to move to the positioning ring. The locking block abuts against the inner wall of the washer, making it difficult for the grinding component to slide. Then, rotating the turntable can switch to the next grinding component to connect with the drive rod.

[0011] This feature, with its positioning ring, washer, spring, and inclined plate, provides precise positioning and limiting after the grinding component disengages from the drive rod. This prevents the grinding component from sliding freely during turntable rotation, ensuring the stability and accuracy of the grinding component switching process.

[0012] Preferably, a support plate is installed on one side of the base, and a bracket is installed on the support plate. The bracket includes a disc and several skeletons on the outer side of the disc. The skeletons are located at the bottom of the turntable and are arranged radially. A rotating shaft is installed in the middle of the bracket, and the rotating shaft is rotatably connected to the bottom shaft hole of the turntable.

[0013] This configuration, combining a support plate, bracket, and rotating shaft, provides a stable support structure for the turntable, distributing the force during rotation, enhancing the smoothness of rotation, and reducing wobbling.

[0014] Preferably, a limit block is installed at the outer end of the bracket, which limits the outer side of the turntable.

[0015] This feature sets a limit block to restrict the outer side of the turntable, further constraining the turntable's rotation range and preventing it from deviating or leaving the track during rotation.

[0016] Preferably, the grinding head is in the shape of a disc, a hemispherical or frustum.

[0017] This feature offers a variety of grinding heads in different shapes to meet the grinding needs of different parts and shapes of metal components.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] In this multi-functional grinding device for metal parts, multiple grinding components with grinding heads of different shapes are radially installed on the side of the turntable. By rotating the turntable, different grinding components can be connected to the output end of the drive motor, realizing the rapid switching of grinding heads of various shapes such as disc, hemispherical, and frustum. This can meet the grinding needs of metal parts with different shapes and precision, and significantly improve the multi-functionality of the device.

[0020] The grinding assembly and drive motor are connected via a plug-in joint and secured by a locking block and a limiting groove, making operation simple. When switching grinding assemblies, simply pull the assembly outwards to disengage the locking block from the limiting groove, move it to the positioning ring where it abuts against the washer, and then rotate the turntable to complete the connection of the next grinding assembly. No complicated disassembly and installation steps are required, greatly improving operational convenience and saving time and labor costs.

[0021] On the one hand, the bracket is rotatably connected to the bottom shaft hole of the turntable via a rotating shaft, and a limiting block is provided at the outer end to limit the outer side of the turntable, providing a stable support structure for the rotation of the turntable and reducing the shaking during the rotation process; on the other hand, the stable snap-fit ​​between the grinding component and the drive motor, as well as the positioning ring and washer limiting the grinding component, ensure the overall stability of the device during the grinding process, reduce equipment wear caused by frequent equipment or grinding head replacements, and extend the service life of the equipment.

[0029] 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.

[0030] This utility model provides a multi-functional grinding device for metal parts, such as... Figure 1 , Figure 3 As shown, it includes a base 1, a turntable 2 is installed on one side of the base 1, and several grinding components 4 are radially installed on the side of the turntable 2. A drive motor 3 is installed on the top of the base 1. The turntable 2 drives different grinding components 4 to connect with the output end of the drive motor 3 by rotating, thereby realizing the switching of different grinding components 4. Different shaped grinding heads 42 are installed on the grinding components 4.

[0031] By combining the base 1, turntable 2 and multiple grinding components 4, the grinding heads 42 of different shapes can be quickly switched to meet the diverse grinding needs of metal parts. This eliminates the need to frequently replace the entire equipment or manually disassemble the grinding heads 42, thereby improving processing efficiency and reducing labor costs. At the same time, the multiple grinding heads 42 are suitable for different processing scenarios, improving grinding precision and quality.

[0032] In this embodiment, Figure 1 , Figure 3 , Figure 4 As shown, the grinding assembly 4 includes a connecting rod 41, a drive rod 31 is installed at the output end of the drive motor 3, a socket 32 ​​is provided at the end of the drive rod 31, one end of the connecting rod 41 is inserted into the socket 32, and a grinding head 42 is installed at the other end of the connecting rod 41.

[0033] In the grinding assembly 4, the connecting rod 41 and the end socket 32 ​​of the drive rod 31 are connected by a plug-in joint, which makes the connection operation between the grinding assembly 4 and the drive motor 3 simple and quick, and the installation and disassembly process is simple. It is easy to quickly replace the grinding assembly 4 and further improve the processing efficiency. At the same time, the plug-in structure can ensure effective power transmission and make the grinding head 42 work stably.

[0034] Specifically, such as Figure 3 , Figure 4 As shown, the inner wall of the socket 32 ​​is provided with a limiting groove 321 along the direction of the drive rod 31, and a slot 43 is provided on one side of the connecting rod 41. A locking block 44 is provided in the slot 43, and the locking block 44 engages with the limiting groove 321.

[0035] The locking groove 321 on the inner wall of the socket 32 ​​and the locking block 44 in the slot 43 of the connecting rod 41 provide a stable fixing method for the connection between the grinding component 4 and the drive motor 3, preventing the grinding component 4 from loosening or falling off during the grinding process, and ensuring the stability and safety of the grinding operation; at the same time, this locking structure makes it easy to quickly separate when the grinding component 4 needs to be switched, without affecting the convenience of operation.

[0036] Furthermore, Figure 3 , Figure 5 As shown, a positioning ring 21 is installed on the turntable 2 near the connecting rod 41. A washer 211 is installed on the inner wall of the positioning ring 21. Several springs 441 are installed at the bottom of the locking block 44. One end of the locking block 44 is provided with a bevel 442. When the grinding component 4 is pulled outward to disengage from the drive rod 31, the connecting rod 41 moves outward, thereby driving the locking block 44 to move to the positioning ring 21. The locking block 44 abuts against the inner wall of the washer 211, making it difficult for the grinding component 4 to slide. Then, the turntable 2 can be rotated to switch the next grinding component 4 to dock with the drive rod 31.

[0037] The positioning ring 21 and washer 211 on the turntable 2, together with the spring 441 and inclined surface 442 at the bottom of the locking block 44, play a precise positioning and limiting role after the grinding component 4 is separated from the drive rod 31, preventing the grinding component 4 from sliding randomly during the rotation of the turntable 2, and ensuring the stability and accuracy of the switching process of the grinding component 4. The elastic force provided by the spring 441 ensures that the locking block 44 and the washer 211 are tightly pressed together, and the design of the inclined surface 442 facilitates the smooth entry and exit of the locking block 44 into the limiting structure, making the switching operation of the grinding component 4 smoother.

[0038] Furthermore, as shown in the figure, Figure 2 As shown, a support plate 11 is installed on one side of the base 1, and a bracket 12 is installed on the support plate 11. The bracket 12 includes a disc and several skeletons on the outside of the disc. The skeletons are located at the bottom of the turntable 2 and are arranged radially. A rotating shaft 122 is installed in the middle of the bracket 12, and the rotating shaft 122 is rotatably connected to the bottom shaft hole of the turntable 2.

[0039] The combination of the support plate 11, bracket 12 and rotating shaft 122 on the base 1 provides a stable support structure for the turntable 2, disperses the force on the turntable 2 when it rotates, enhances the smoothness of the turntable 2 rotation and reduces shaking; the radial arrangement of the bracket 12 frame effectively improves the load-bearing capacity and stability of the bracket 12, ensuring that the turntable 2 can still operate reliably when multiple grinding components 4 are installed, providing a stable foundation for grinding operations.

[0040] Furthermore, such as Figure 2 As shown, a limit block 121 is installed at the outer end of the bracket 12, which limits the outer side of the turntable 2.

[0041] The limiting block 121 at the outer end of the bracket 12 limits the outer side of the turntable 2, further constraining the rotation range of the turntable 2, preventing the turntable 2 from deviating or leaving the track during rotation, ensuring the accuracy and reliability of the turntable 2's rotation, improving the stability of the entire device's operation, and avoiding problems such as inaccurate docking of the grinding components 4 or equipment failure caused by the turntable 2's deviation.

[0042] Furthermore, such as Figure 1 As shown, the grinding head 42 has a disc-shaped, hemispherical, or frustum-shaped structure.

[0043] The grinding heads 42 of various shapes are suitable for grinding different parts and shapes of metal parts. The disc-shaped grinding head 42 is suitable for grinding large-area flat surfaces, the hemispherical grinding head 42 is easy to handle arc surfaces or curved surfaces, and the frustum-shaped grinding head 42 can be used for grinding corners or conical parts, which enriches the grinding function of the device, improves the processing adaptability of complex-shaped metal parts, and meets diverse production needs.

[0044] When using the multifunctional grinding device for metal parts of this utility model, first place the metal parts on a suitable worktable, connect the power supply of the drive motor 3, and ensure that the device is in a working state. At this time, the initial grinding component 4 is connected to the output end of the drive motor 3, and the grinding head 42 is in a standby position.

[0045] When it is necessary to change the grinding head 42 for different types of grinding operations, the operator pulls the grinding assembly 4 outward. During this process, the connecting rod 41 moves outward, causing the locking block 44 in the locking slot 43 to move. Since the locking block 44 has a spring 441 installed at its bottom and a bevel 442 at one end, when pulled outward, the locking block 44 is squeezed, and the spring 441 is compressed until the locking block 44 disengages from the limiting groove 321 on the inner wall of the insertion port 32 at the end of the drive rod 31. When the locking block 44 moves to the positioning ring 21 on the turntable 2, the spring 441 returns to its elasticity, and the locking block 44 abuts against the washer 211 on the inner wall of the positioning ring 21, thereby fixing the grinding assembly 4 in place and preventing it from sliding. Next, the operator rotates the turntable 2. The turntable 2 rotates through the rotational connection between its bottom and the rotating shaft 122 in the middle of the bracket 12. At the same time, the limiting block 121 at the outer end of the bracket 12 limits the rotation range of the turntable 2 to ensure its stable rotation. The turntable 2 rotates, causing different grinding components 4 to move to the output position of the drive motor 3. When the required grinding component 4 reaches the corresponding position, the grinding component 4 is pushed so that one end of the connecting rod 41 is inserted into the socket 32 ​​of the drive rod 31. At the same time, the locking block 44 slides along the limiting groove 321 and locks in, realizing a stable connection between the grinding component 4 and the drive motor 3, and completing the switching of the grinding head 42.

[0046] Grinding Operation: After the grinding assembly 4 is connected to the drive motor 3, the drive motor 3 is started. The drive motor 3 drives the connecting rod 41 of the grinding assembly 4 to rotate via the drive rod 31, thereby causing the grinding head 42 to rotate at high speed. The operator brings the metal parts to be ground close to the grinding head 42. According to the shape of the grinding head 42 (disc-shaped, hemispherical, or frustum-shaped) and the grinding requirements of the metal parts, the operator adjusts the contact angle and position between the metal parts and the grinding head 42 to perform the corresponding grinding operation. For example, a disc-shaped grinding head 42 is used for flat surface grinding, a hemispherical grinding head 42 is used for arc surfaces, and a frustum-shaped grinding head 42 is used for grinding edges and corners. During the grinding process, the positioning ring 21, washer 211, locking block 44, limiting groove 321, and other structures cooperate with each other to ensure the stability of the connection between the grinding assembly 4 and the drive motor 3, prevent the grinding assembly 4 from loosening or falling off, and ensure the smooth progress of the grinding operation.

[0047] Reset after grinding: After the grinding operation is completed, turn off the drive motor 3. After the grinding head 42 stops rotating, pull the grinding component 4 outward again to disengage it from the drive rod 31. The locking block 44 moves to the positioning ring 21 and abuts. Rotate the turntable 2 to remove the used grinding component 4. If other grinding operations are required, other grinding components 4 can be switched according to the above steps. If grinding is not required, return all parts of the device to their positions, turn off the power, and complete the entire workflow.

[0048] Finally, it should be noted that the electronic components in the drive motor 3 and other components in this embodiment are all general standard parts or parts known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. In the idle part of this device, all the above-mentioned electrical components are connected by wires. The specific connection method should refer to the working order between the electrical components in the above working principle to complete the electrical connection. All of these are technologies known in the art.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
