Abstract
Description
Technical Field
[0001] This utility model relates to the field of hardware polishing technology, specifically a burr polishing device for hardware processing. Background Technology
[0002] During the processing of hardware parts (such as cutting, stamping, drilling, milling, etc.), burrs are generated. These burrs are tiny protrusions or fragments left on the metal edges. Burr removal is an important post-processing step in hardware processing. Using a burr removal device can quickly process the surface of hardware parts, thereby ensuring the quality of the hardware parts when they leave the factory. However, in use, because the position of traditional burr removal devices is not easy to move when removing burrs, some parts cannot completely contact the removal components and remove burrs, affecting the overall quality of burr removal.
[0003] To overcome the aforementioned deficiencies, existing technology (Chinese Patent No. CN220881686U, Publication Date 2024-05-03) provides a deburring and polishing machine for hardware production, comprising a polishing machine body; a bidirectional worm gear rotatably mounted on the upper part of the polishing machine body via bearings; and a support bracket slidably mounted inside the polishing machine body; wherein a first bidirectional threaded rod rotatably mounted inside the positioning frame via bearings; wherein guide slide rods are fixedly installed front and rear inside the support bracket; and wherein symmetrically mounted cleaning rollers have cleaning toothed columns rotatably mounted at equal intervals inside, with guide gears fixedly mounted at the front ends of the cleaning toothed columns above the cleaning rollers. This deburring and polishing machine for hardware production positions the hardware parts through the positioning bracket of the positioning frame inside the polishing machine body, while the height-adjustable support bracket drives the cleaning rollers to rise and fall, achieving the deburring effect through the rotation of the cleaning toothed columns. It is adaptable to hardware parts of different specifications and improves deburring efficiency.
[0004] The aforementioned mechanism improves the efficiency of burr removal by using a height adjustment mechanism to adapt to hardware parts of different specifications. However, in actual use, the high-speed friction during polishing of the hardware parts causes the hardware parts to heat up, affecting the subsequent quality of the hardware parts. Utility Model Content
[0005] The purpose of this utility model is to provide a burr removal device for hardware processing, so as to solve the problems mentioned in the background art, that the traditional burr removal device is not easy to move when removing hardware, which causes some parts to not be able to completely contact the removal component and remove burrs, and the hardware temperature rises during removal, resulting in a decrease in the surface quality of the hardware.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a burr-removing device for hardware processing, comprising a fixed base plate, a support frame mounted on the top of the fixed base plate, and a pneumatic telescopic rod slidably connected to the top of the support frame, a grinding component mounted on the output end of the pneumatic telescopic rod, and a chip removal groove formed on the top of the fixed base plate; a drive motor is provided on the top of the support frame, and a position adjustment mechanism for adjusting the position of the grinding component is provided on the output end of the drive motor, the position adjustment mechanism comprising a threaded rod, the threaded rod being fixedly connected to the output end of the drive motor, a movable block being threadedly connected to the outer side of the threaded rod, and a slider being fixedly connected to the bottom end of the movable block, the bottom end of the slider being connected to the top of the pneumatic telescopic rod; electric slide rail assemblies are fixedly connected to the left and right sides of the top of the fixed base plate, and a limit plate is connected to the inner side of the electric slide rail assembly through a sliding block, and a cleaning mechanism for cleaning dust from the surface of the fixed base plate is provided on the top of the limit plate.
[0007] Furthermore, a sliding groove is provided at the top of the support frame, and the movable block and the support frame are connected by a slider and the sliding groove to form a sliding mechanism.
[0008] Furthermore, the cleaning mechanism includes a propulsion block, which is fixedly connected to the top of the limiting plate, and the cross-section of the propulsion block is triangular.
[0009] Furthermore, the limiting plate and the sliding block are rotatably connected, and the bottom end of the limiting plate is in contact with the surface of the fixed base plate. The side height of the limiting plate is the same as the bottom height of the limiting plate.
[0010] Furthermore, the side of the threaded rod is connected to a cam via a sprocket transmission mechanism, and an extrusion plate is installed at the upper end of the side of the support frame. A water storage soft bag is provided at the bottom end of the extrusion plate, and a nozzle is installed at the bottom end of the water storage soft bag via a hose. The position of the nozzle corresponds to the position of the grinding component.
[0011] Furthermore, connecting springs are installed at both ends of the extrusion plate, and the extrusion plate and the water-storing soft bag form an elastic structure through the connecting springs.
[0012] Furthermore, the top of the fixed base plate is provided with a placement groove, and the grinding component is disposed above the placement groove.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. The output end of the drive motor rotates, which in turn drives the threaded rod to rotate. The outer thread of the threaded rod is connected to a movable block, and the bottom end of the movable block is connected to a slider. Therefore, the slider can drive the pneumatic telescopic rod and the grinding assembly to move, so that the position of the grinding assembly can be flexibly adjusted according to the grinding requirements of the hardware. At the same time, when the hardware is being ground, the position of the hardware can be finely adjusted by adjusting the position of the limit plate through the grinding assembly. The hardware can move and adjust its position within the range inside the placement groove.
[0015] Furthermore, as the movable block moves, it causes the slider to move inside the groove, preventing the movable block from deflecting at an angle during movement. This results in a smoother movement of the movable block and increased stability during use.
[0016] Furthermore, by rotating the limiting plate, the side of the limiting plate is made to fit against the top of the fixed base plate. The movement of the sliding block inside the electric slide rail assembly causes the limiting plate to move on the surface of the fixed base plate. The push block set on the surface of the limiting plate pushes the dust accumulated on the top of the fixed base plate, so that the dust is pushed by the tip of the push block and moves to both sides, allowing the dust to fall from the chip discharge groove, effectively reducing the dust residue on the surface of the fixed base plate.
[0017] 2. As the cam rotates, it continuously squeezes the extrusion plate, which in turn squeezes the water storage bladder at the bottom of the extrusion plate. The water inside the water storage bladder is then transported to the nozzle through a hose. The nozzle sprays cooling water onto the surface of the hardware and grinding components, thereby simultaneously cooling the hardware and grinding components and preventing heat damage.
[0018] Furthermore, after the extrusion plate is squeezed, when the cam rotates to another angle to reset, the extrusion plate automatically resets through the elastic force of the connecting spring, so that the water storage soft bag also resets synchronously. This facilitates the water pump to store water into the water storage soft bag, ensuring that there is always cooling water waiting to be discharged by pressing. In addition, a one-way valve is installed at the water inlet of the water storage soft bag to prevent the cooling water from flowing back when it is squeezed to drain. Attached Figure Description

[0026] 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.
[0027] Example 1: As Figure 1 , Figure 3 , Figure 4 and Figure 5 The technical solution shown addresses the problem that traditional deburring devices are difficult to move during deburring of metal parts, resulting in some areas not fully contacting the deburring components and thus affecting the overall deburring quality. This deburring device for metal parts processing discloses a position adjustment mechanism, including a fixed base plate 1. A support frame 2 is mounted on the top of the fixed base plate 1, and a pneumatic telescopic rod 3 is slidably connected to the top of the support frame 2. A deburring component 4 is mounted on the output end of the pneumatic telescopic rod 3. A chip removal mechanism is provided at the top of the fixed base plate 1. The top of the support frame 2 is provided with a drive motor 10, and the output end of the drive motor 10 is provided with a position adjustment mechanism for adjusting the position of the grinding component 4. The position adjustment mechanism includes a threaded rod 11, which is fixedly connected to the output end of the drive motor 10. A movable block 12 is threadedly connected to the outer side of the threaded rod 11, and a slider 13 is fixedly connected to the bottom end of the movable block 12. The bottom end of the slider 13 is connected to the top of the pneumatic telescopic rod 3. A sliding groove 14 is provided at the top of the support frame 2, and the movable block 12 and the support frame 2 are connected by the slider 13 and the sliding groove 14 to form a sliding mechanism.
[0028] In this example, the hardware to be processed is placed at the top of the placement slot 7. The electric slide rail assembly 5 drives the internal sliding block to move, so that the limiting plate 6 is synchronously driven to clamp and fix the hardware. The height of the grinding assembly 4 can be adjusted by the pneumatic telescopic rod 3. The grinding assembly 4 is rotated by the internal motor to grind the burrs on the surface of the hardware. After grinding, the output end of the drive motor 10 rotates and drives the threaded rod 11 to rotate. The outer thread of the threaded rod 11 is connected to the movable block 12, and the bottom end of the movable block 12 is connected to the slider 13. Therefore, the slider 13 can carry... The pneumatic telescopic rod 3 and the grinding assembly 4 move, allowing the position of the grinding assembly 4 to be flexibly adjusted according to the grinding requirements of the hardware. At the same time, when the hardware is being ground, the position of the limiting plate 6 can be adjusted through the grinding assembly 4 to achieve fine adjustment of the hardware position. The hardware can move and adjust its position within the range inside the placement groove 7. During the movement of the movable block 12, it will drive the slider 13 to move inside the slide groove 14, so that the angle of the movable block 12 will not deflect during the movement, thus making the movement of the movable block 12 more stable and increasing the stability during use.
[0029] Example 2: Figure 1 , Figure 3 , Figure 5 and Figure 6 The technical solution shown addresses the problem of temperature rise and surface quality degradation of hardware parts during polishing. The hardware part deburring device discloses a spray mechanism. A cam 15 is connected to the side of the threaded rod 11 via a sprocket transmission mechanism. A pressing plate 16 is installed at the upper end of the side of the support frame 2. A water-storing soft bag 17 is provided at the bottom of the pressing plate 16, and a nozzle 19 is installed at the bottom of the water-storing soft bag 17 via a hose. The position of the nozzle 19 corresponds to the position of the polishing component 4. Connecting springs 18 are installed at both ends of the pressing plate 16, and the pressing plate 16 and the water-storing soft bag 17 form an elastic structure through the connecting springs 18. A placement groove 7 is provided at the top of the fixed base plate 1, and the polishing component 4 is positioned above the placement groove 7.
[0030] In this example, when the threaded rod 11 rotates, it drives the cam 15 to rotate via the sprocket transmission mechanism. As the cam 15 rotates, it continuously squeezes the extrusion plate 16, thereby simultaneously squeezing the water storage bladder 17 at the bottom of the extrusion plate 16. The water inside the water storage bladder 17 is transported to the nozzle 19 through a hose. The nozzle 19 sprays cooling water onto the surface of the hardware and the grinding assembly 4, thereby simultaneously cooling the hardware and the grinding assembly 4 and preventing heat damage. After the extrusion plate 16 is squeezed, when the cam 15 rotates to another angle to reset, the extrusion plate 16 automatically resets due to the elasticity of the connecting spring 18, thereby simultaneously resetting the water storage bladder 17. This allows the water pump to store water inside the water storage bladder 17, ensuring that there is always cooling water waiting to be squeezed out. Furthermore, a one-way valve is installed at the inlet of the water storage bladder 17 to prevent the cooling water from flowing back when it is squeezed out.
[0031] Example 3: Figures 1-4 The technical solution shown addresses the problem that dust and debris fall onto the surface of the fixed base plate 1 after polishing of hardware parts, and excessive dust residue can affect the stability of subsequent hardware placement. The hardware part processing deburring device discloses a cleaning mechanism. Electric slide rail assemblies 5 are fixedly connected to the left and right sides of the top of the fixed base plate 1. The inner side of the electric slide rail assembly 5 is connected to a limit plate 6 via a sliding block. The top of the limit plate 6 is equipped with a cleaning mechanism for cleaning dust from the surface of the fixed base plate 1. The cleaning mechanism includes a pushing block 9, which is fixedly connected to the top of the limit plate 6. The pushing block 9 has a triangular cross-section. The limit plate 6 and the sliding block are rotatably connected, and the bottom end of the limit plate 6 is in contact with the surface of the fixed base plate 1. The side height of the limit plate 6 is the same as the bottom height of the limit plate 6.
[0032] In this example, after burr removal, dust and debris fall onto the surface of the fixed base plate 1. Some of the dust will fall from the chip removal groove 8 due to the push of the clamping hardware by the limiting plate 6, while some dust will remain on the surface of the fixed base plate 1. The sliding block inside the electric slide rail assembly 5 is rotatably connected to the limiting plate 6. By rotating the limiting plate 6, the side of the limiting plate 6 is made to fit against the top of the fixed base plate 1. By moving the sliding block inside the electric slide rail assembly 5, the limiting plate 6 moves on the surface of the fixed base plate 1. The pushing block 9 on the surface of the limiting plate 6 pushes the dust accumulated at the top of the fixed base plate 1, so that the dust is pushed by the tip of the pushing block 9 and moves to both sides, so that the dust can fall from the chip removal groove 8, effectively reducing the dust residue on the surface of the fixed base plate 1.
[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
