Description

Technical Field

[0001] This invention belongs to the technical field of metal polishing, and in particular relates to a surface polishing device for preventing scratches on hardware parts. Background Technology

[0002] Hardware refers to various tools, parts and products made of metal, and is widely used in industrial manufacturing, construction engineering, home life and infrastructure. Hardware is often used to reliably connect two or more independent parts together to form a stable whole. During use, hardware directly or indirectly bears the weight of the structure and object. Among them, hardware with threaded structure is the most widely used and core type of hardware. They achieve the functions of connection, fastening, sealing, transmission and adjustment through the helical structure of the thread.

[0003] During the processing of common hardware parts, surface grinding is required to facilitate subsequent installation and use. Grinding is performed by moving the grinding equipment along the surface of the hardware part. However, in actual operation, the reciprocating movement of the grinding equipment can easily carry residual grinding debris along with it, causing additional wear on the hardware surface. Furthermore, the isolation between different equipment operations can affect the grinding speed. Therefore, we provide a scratch-resistant hardware surface grinding device to solve the above-mentioned technical problems. Summary of the Invention

[0016] The present invention has the following beneficial effects: 1. The present invention sets up a switching support component, which uses the rotation of the inner and outer gear rings to drive the rotation of the control transmission gear, and then drives the arc-shaped transmission block to rotate. Under the action of the arc-shaped transmission block and the arc-shaped limiting groove, the corresponding limiting threaded tube rotates. Under the action of the limiting threaded tube and the hardware, the position of the hardware is limited. When the switching drive gear rotates and drives the switching transmission gear to rotate a certain angle, the switching support plate rotates synchronously by a certain angle, thereby realizing the transfer of hardware, facilitating the switching of workstations during the processing and improving operating efficiency.

[0017] 2. This invention, by setting up a switching support assembly, a feeding mechanism, and a unloading mechanism, when the inner and outer toothed rings rotate, under the connecting action of the extension connecting rod, the clamping and limiting assembly opposite to the feeding support assembly gradually restricts the hardware parts on the switching support assembly. When the inner and outer toothed rings rotate in opposite directions, the clamping and limiting assembly opposite to the unloading support assembly gradually moves the hardware parts out of the switching support assembly, thereby realizing the position limitation and release of the hardware parts, avoiding the position displacement of the hardware parts during the grinding process, and facilitating the removal of the ground hardware parts.

[0018] 3. This invention, by setting up a switching support component and a grinding component, rotates the inner and outer gear rings, driving the regulating screw to rotate synchronously, causing the grinding support frame to move downwards. When the grinding belt is opposite to the hardware, the regulating transmission plate moves horizontally, and the two second grinding wheels approach the hardware, forming a grinding wrap angle between the grinding belt and the hardware. As the grinding support frame moves downwards, the grinding belt moves along the surface of the hardware, thereby realizing the grinding operation of the hardware. This facilitates the control of the contact between the grinding belt and the hardware, and the grinding belt moves in a single direction to perform grinding, avoiding secondary wear on the grinding surface caused by debris.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] For a specific implementation example, please refer to Implementation Example 1. Figure 1-10The present invention is a surface polishing device for anti-scratch hardware parts, including a switching support assembly 1. Specifically, a feeding mechanism 2 and an unloading mechanism 3 are fixedly arranged around the switching support assembly 1. Both the feeding mechanism 2 and the unloading mechanism 3 include clamping and limiting components 4. The feeding mechanism 2 also includes a feeding support assembly 5, which is fixedly connected to the corresponding clamping and limiting component 4. The unloading mechanism 3 also includes an unloading support assembly 6, which is fixedly connected to the corresponding clamping and limiting component 4.

[0033] Furthermore, the switch support component 1 is used to limit the position of the hardware and allows for position switching between hardware components; The loading mechanism 2 and the unloading mechanism 3 are used to load and unload hardware parts respectively, and the clamping and limiting component 4 is used to restrict the hardware parts to or transfer them out of the switching support component 1.

[0034] The operation process of this embodiment is as follows: The clamping and limiting component 4 corresponding to the feeding mechanism 2 is used to transfer the hardware to a position opposite to the switching support component 1. The feeding support component 5 drives the corresponding clamping and limiting component 4 and the hardware to move downwards until the switching support component 1 limits the position of the hardware. The switching support component 1 rotates a certain angle to switch the work position, so that the hardware limited on the switching support component 1 is opposite to the grinding component 7. The grinding component 7 is used to grind the surface of the hardware. During this process, the feeding mechanism 2 performs a feeding operation to lower the hardware. After the grinding is completed, the switching support component 1 again... Rotate at a certain angle so that the polished hardware is opposite to the unloading mechanism 3. The unloading support component 6 drives the corresponding clamping limit component 4 to move down until the corresponding clamping limit component 4 is opposite to the hardware. The clamping limit component 4 is used to clamp and fix the polished hardware. The unloading support component 6 drives the corresponding clamping limit component 4 and the hardware to move until the hardware is transferred and away from the switching support component 1, thus completing the polishing process of the hardware. At the same time, the feeding mechanism 2 feeds the hardware and the polishing component 7 polishes the hardware. This cycle is repeated to realize the sequential processing of batches of hardware.

An adjustment transmission gear 110 corresponding to the control support plate 104 is rotatably disposed on the lower surface of the hollow support frame 101, and the adjustment transmission gear 110 is fixedly connected to the corresponding support shaft.

[0037] Furthermore, an inner and outer gear ring 111 is rotatably provided on the lower surface of the hollow support frame 101. The inner and outer gear ring 111 meshes with two regulating transmission gears 110. The regulating transmission gears 110 are located inside the inner and outer gear rings 111, and mesh with the inner tooth structure of the inner and outer gear rings 111. A regulating gear 112 is rotatably connected to the periphery of the hollow support frame 101 through an extension support plate. A regulating motor is fixedly installed on the upper surface of the extension support plate. The output shaft of the regulating motor is fixedly connected to the regulating gear 112. The regulating gear 112 meshes with the inner and outer gear rings 111. The regulating gear 112 is located outside the inner and outer gear rings 111, and meshes with the outer tooth structure of the inner and outer gear rings 111.

[0038] Furthermore, the loading support assembly 5 and the unloading support assembly 6 are respectively opposite to two of the control support plates 104. The loading support assembly 5 is located at the loading station for loading hardware parts, and the unloading support assembly 6 is located at the unloading station for unloading hardware parts. Both the loading support assembly 5 and the unloading support assembly 6 include a hollow support column 501 fixedly connected by an L-shaped support frame. The hollow support column 501 has a control slide 502 on its peripheral side. The control slide 502 is formed by connecting a vertical slide and a horizontal slide. The hollow support column 501 is rotatably connected internally. There is a lifting screw 503, and a material transmission drive gear 504 is rotatably installed on the lower surface of the L-shaped support frame. The material transmission drive gear 504 is fixedly connected to the lifting screw 503 and meshes with the inner and outer gear rings 111. A transmission internal thread tube 505 is slidably installed inside the hollow support column 501. The transmission internal thread tube 505 is threadedly engaged with the lifting screw 503. An extension connecting rod 506 is fixedly connected to the circumferential side of the transmission internal thread tube 505. The extension connecting rod 506 is slidably engaged with the regulating slide 502 and is fixedly connected to the corresponding clamping and limiting component 4.

[0039] Furthermore, the control slide 502 is composed of a vertical slide and a horizontal slide connected together. The feeding support component 5 is connected to the upper end of the horizontal slide and the vertical slide of the control slide 502. The unloading support component 6 is connected to the lower end of the horizontal slide and the vertical slide of the control slide 502. In the initial state, the extension link 506 corresponding to the feeding support component 5 is located at the end of the horizontal slide of the control slide 502, and the extension link 506 corresponding to the unloading support component 6 is located at the upper end of the vertical slide.

[0040] Furthermore, the clamping and limiting assembly 4 includes a support plate 401 fixedly connected to the extension link 506. A guide groove is provided on one side of the support plate 401. A transmission screw 402 is rotatably connected inside the guide groove. A lifting motor is fixedly installed on the upper surface of the support plate 401. The output shaft of the lifting motor is fixedly connected to the transmission screw 402. A lifting transmission block that is threadedly engaged with the transmission screw 402 is slidably arranged inside the guide groove. A lifting transmission plate 403 is fixedly connected to one side of the lifting transmission block. First transmission columns 404 are fixedly connected to both ends of the lifting transmission plate 403.

[0041] Two L-shaped transmission rods 405 are symmetrically rotatably connected to one side of the support plate 401 near the guide groove. The surfaces of the L-shaped transmission rods 405 are respectively provided with a first slide rail 406 and a second slide rail 407. The first slide rail 406 is slidably engaged with the corresponding first transmission column 404. A limiting crossbar 408 is fixedly connected to one side of the support plate 401 near the guide groove. Two limiting clamps 409 are symmetrically slidably arranged on the surface of the limiting crossbar 408. The clamping surface of the limiting clamps 409 is made of a rough material structure to facilitate the position limitation of the hardware. A second transmission column 410 is fixedly connected to one side of the limiting clamps 409. The second transmission column 410 is slidably engaged with the second slide rail 407.

[0042] The operation process of this embodiment is as follows: When the feeding support assembly 5 performs the feeding operation, the hardware is placed between the two limiting clamping frames 409 of the clamping and limiting assembly 4 opposite to the feeding support assembly 5. The clamping and limiting assembly 4 is used to limit the position of the hardware. The lifting motor is started to drive the transmission screw 402 to rotate. Under the threaded cooperation between the transmission screw 402 and the lifting transmission block, the lifting transmission block slides upward along the inside of the guide groove. Under the connection of the lifting transmission plate 403, the two first transmission columns 404 move upward synchronously. Under the sliding cooperation between the first transmission column 404 and the first slide rail 406, the two L-shaped transmission connecting rods 405 rotate synchronously. Under the sliding cooperation between the second transmission column 410 and the second slide rail 407, the two limiting clamping frames 409 slide horizontally along the surface of the limiting crossbar 408 until the two limiting clamping frames 409 are in close contact with the surface of the hardware, thereby limiting the position of the hardware.

[0043] The start-up control motor drives the control gear 112 to rotate. Under the meshing action of the control gear 112 and the inner and outer gear rings 111, the inner and outer gear rings 111 rotate. Under the meshing action of the inner and outer gear rings 111 and the material transmission drive gear 504 corresponding to the feeding support assembly 5, the corresponding material transmission drive gear 504 rotates. The lifting screw 503 rotates synchronously. Since the extension connecting rod 506 corresponding to the feeding support assembly 5 is located inside the horizontal slide of the control slide 502 in the initial stage, the extension connecting rod 506 and the transmission internal thread tube 505 are unrestricted. The transmission internal thread tube 505 rotates synchronously with the lifting screw 503, and the extension connecting rod 506 slides along the horizontal slide. Under the connection of 6, the corresponding clamping and limiting component 4 and hardware move horizontally synchronously until the extension rod 506 moves into the vertical slide. At this point, the hardware is located directly above the corresponding limiting threaded tube 105. As the lifting screw 503 continues to rotate, due to the limitation of the vertical slide, the extension rod 506 is driven to slide downward along the vertical slide by the threaded engagement of the lifting screw 503 and the transmission internal threaded tube 505. The clamping and limiting component 4 and hardware move downward synchronously. During the rotation of the inner and outer gear rings 111, the meshing action of the inner and outer gear rings 111 and the regulating transmission gear 110 further... The regulating transmission gear 110, which is opposite to the feeding support assembly 5, rotates. Under the connection of the support shaft, the corresponding arc-shaped transmission block 109 rotates. Through the cooperation of the arc-shaped transmission block 109 and the arc-shaped limiting groove 106, the corresponding regulating support plate 104 rotates, which in turn drives the limiting threaded tube 105, which is opposite to the hardware, to rotate. When the threaded part at the lower end of the hardware contacts the limiting threaded tube 105, the limiting threaded tube 105 limits the position of the hardware through the threaded cooperation between the two. After the position of the hardware is limited, the lifting motor drives the transmission screw 402 to rotate in the opposite direction. Under the connection of the lifting transmission plate 403, the two first transmission columns 4 04. Simultaneously move downwards, L-shaped transmission link 405 rotates in the opposite direction, thereby driving the two limit clamping frames 409 to move in the opposite direction, gradually moving away from the hardware. The control motor drives the control gear 112 to rotate in the opposite direction, and the inner and outer gear rings 111 rotate in the opposite direction, thereby causing the lifting screw 503 to rotate. Under the sliding cooperation of the extension link 506 and the control slide 502, the extension link 506 first drives the clamping limit assembly 4 to move upwards along the vertical slide, moving away from the hardware. The extension link 506 then drives the clamping limit assembly 4 to move horizontally along the horizontal slide, causing the clamping limit assembly 4 to deviate from the hardware and move back to the initial state, thus completing the loading operation of the hardware.

[0044] The drive motor is started to drive the switching drive gear 108 to rotate. Under the meshing action of the switching drive gear 108 and the switching transmission gear 107, the switching transmission gear 107 rotates and drives the drive shaft to rotate synchronously, thereby causing the switching support plate 102 to rotate at a certain angle. The arc-shaped transmission block 109 slides along the arc-shaped transmission groove 103 and the arc-shaped limiting groove 106 until the adjustment support plate 104 equipped with hardware parts is opposite to the grinding component 7, thereby changing the work position.

[0045] For a specific embodiment three, please refer to Figure 1-10 Based on specific embodiments one and two, specifically, the grinding component 7 is opposite to another control support plate 104. The grinding component 7 is located at the grinding station and is used to grind hardware parts. The grinding component 7 includes a lifting guide rail 701 fixedly connected by a support frame. A control screw 702 is rotatably connected inside the lifting guide rail 701. A grinding transmission gear 703 is rotatably arranged on the lower surface of the support frame. The grinding transmission gear 703 is fixedly connected to the control screw 702. The grinding transmission gear 703 meshes with the inner and outer gear rings 111. A grinding support frame 704 is slidably arranged inside the lifting guide rail 701 and threadedly engaged with the control screw 702. An extension support plate is fixedly connected to one side of the grinding support frame 704. A first grinding wheel 705 is rotatably connected to the lower surface of the extension support plate. Two grinding connecting rods 706 are symmetrically rotatably connected to the upper surface of the extension support plate.

[0046] Furthermore, a second grinding wheel 707 is rotatably connected to the lower surface of the grinding connecting rod 706. A grinding motor is fixedly installed on the upper surface of one of the grinding connecting rods 706. The output shaft of the grinding motor is fixedly connected to the corresponding second grinding wheel 707. The first grinding wheel 705 is connected to the two second grinding wheels 707 through a grinding belt 708. A transmission column 709 is fixedly connected to the upper surface of the grinding connecting rod 706. An electric telescopic rod 710 is installed on the surface of the grinding support frame 704. An adjustment transmission plate 711 is fixedly connected to one end of the electric telescopic rod 710. Two transmission slides are symmetrically opened on the surface of the adjustment transmission plate 711. The transmission slides slide in sliding fit with the corresponding transmission column 709.

[0047] The operation process of this embodiment is as follows: When the hardware is opposite to the grinding assembly 7, the grinding assembly 7 performs a grinding operation. The inner and outer gear rings 111 rotate. Under the meshing action of the inner and outer gear rings 111 and the grinding transmission gear 703, the grinding transmission gear 703 rotates, thereby driving the adjusting screw 702 to rotate. Under the threaded engagement of the adjusting screw 702 and the grinding support frame 704, the grinding support frame 704 moves downward until the grinding belt 708 is opposite to the hardware. Then, the electric telescopic rod 710 is activated to drive the adjusting transmission plate 711 to move horizontally. Under the sliding engagement of the transmission slide and the corresponding transmission column 709, the two grinding connecting rods 706 rotate synchronously. The two grinding connecting rods 706 move closer to each other, causing the two second grinding wheels 707 to gradually approach the hardware. The metal parts and the polishing belt 708 move synchronously. As the polishing belt 708 moves, a polishing angle is formed between the polishing belt 708 and the metal parts. The polishing motor is started, driving the corresponding second polishing wheel 707 to rotate. Under the connection of the polishing belt 708, the two second polishing wheels 707 and the first polishing wheel 705 rotate synchronously. The polishing belt 708 moves back and forth to polish the metal parts. At the same time, the polishing support frame 704 continues to move downward, and the polishing belt 708 moves downward along the surface of the metal parts, thereby realizing the polishing operation on the peripheral side of the metal parts. The polishing belt 708 moves in a single direction during polishing, which drives the polished debris to move synchronously, avoiding reciprocating movement and causing wear on the surface of the metal parts. During this process, the feeding support assembly 5 continues to perform the feeding operation.

[0048] After the grinding operation is completed, the switching support plate 102 rotates again by a certain angle, so that the ground hardware is opposite to the unloading support assembly 6. The inner and outer gear rings 111 rotate, and under the meshing action of the inner and outer gear rings 111 and the material transmission drive gear 504 corresponding to the unloading support assembly 6, the extension connecting rod 506 slides along the inside of the control slide 502, thereby driving the corresponding clamping limit assembly 4 to move horizontally and then downward. The clamping limit assembly 4 gradually approaches the ground hardware. When the extension connecting rod 506 moves to the bottom of the vertical slide, the two limit clamping frames 409 are located on both sides of the hardware, and the clamping limit assembly 4 performs... The position limiting operation clamps and restricts the hardware. When the inner and outer gear rings 111 rotate in opposite directions, the extension connecting rod 506 drives the clamping and limiting component 4 and the hardware to gradually move upward. At the same time, under the meshing action of the inner and outer gear rings 111 and the corresponding regulating transmission gear 110, the corresponding regulating transmission gear 110 rotates in opposite directions. Under the action of the threaded structure at the lower end of the hardware and the threaded engagement of the release limiting thread tube 105, the hardware is released until it is disengaged from the limiting thread tube 105. When the clamping and limiting component 4 moves to the initial position, the clamping and limiting component 4 releases the position limiting of the hardware, and the polished hardware is released.
