Description

Technical Field

[0001] This utility model relates to the field of hinge processing technology, specifically to a grinding device for hinge processing. Background Technology

[0002] After the hinge is processed, there will be some burrs on the outer wall of the hinge, which need to be polished.

[0003] In the process of developing this application, the following problems were found with the technology: Most existing hinge processing uses grinding equipment to grind the hinges, but the hinges are prone to vibration during the grinding process, which requires workers to press the hinges during the grinding process.

[0004] Therefore, a grinding device for hinge processing is proposed. Utility Model Content

[0005] The purpose of this invention is to address the problem that most existing hinge processing methods rely on grinding equipment to grind the hinges, but the hinges tend to vibrate during the grinding process, requiring workers to press down on the hinges during grinding. This invention provides a grinding device for hinge processing.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0007] A hinge grinding device includes a base plate, a groove on the upper surface of the base plate, an arc-shaped groove at the bottom of the inner wall of the groove, a slot on the upper surface of the base plate, a grinding mechanism for positioning the hinge during the grinding process provided on the inner wall of the slot, a dust suction mechanism provided on the upper surface of the grinding mechanism, a positioning slot on the front of the base plate, and a positioning mechanism provided inside the positioning slot.

[0008] Furthermore, the grinding mechanism includes a slider one, which is slidably connected to the slot inside the base plate. An L-shaped fixing plate is provided on the upper surface of the slider one, and a slot is opened on the upper surface of the L-shaped fixing plate. Through holes are opened on the inner walls of the front and rear sides of the slot of the L-shaped fixing plate. A screw is rotatably connected inside the two sets of through holes of the L-shaped fixing plate. A motor one is provided on the back of the L-shaped fixing plate, and the output shaft of the motor one is installed on the back of the screw. A slider two is threadedly connected to the outside of the screw. The slider two is slidably connected to the slot inside the L-shaped fixing plate. A U-shaped fixing plate is provided on the lower surface of the slider two. Two sets of universal wheels are installed on the lower surface of the U-shaped fixing plate. The lower surfaces of the two sets of universal wheels abut against the upper surface of the base plate. The position of the lower surfaces of the two sets of universal wheels is parallel to the position of the upper surface of the locking hinge inside the groove of the base plate. A grinding machine is installed on the top of the inner wall of the U-shaped fixing plate. The position of the lower surface of the grinding machine is parallel to the position of the lower surfaces of the two sets of universal wheels.

[0009] Furthermore, the dust collection mechanism includes a support plate, which is installed on the upper surface of the second slider. A vacuum cleaner is provided on the upper surface of the support plate, and a suction pipe is installed on the suction end of the vacuum cleaner. A through hole is opened on the upper surface of the U-shaped fixing plate, and the suction end of the suction pipe is engaged inside the through hole of the U-shaped fixing plate. The suction end of the suction pipe is located on one side of the grinder.

[0010] Furthermore, the positioning mechanism includes a second motor and a bidirectional screw. The inner walls of the left and right sides of the positioning slot of the base plate are provided with through holes. The bidirectional screw is rotatably connected to the two sets of through holes in the base plate. The second motor is installed on the right side of the base plate, and the output shaft of the second motor is installed at the right end of the bidirectional screw. The external threads of the bidirectional screw are connected to two sets of fixing blocks. The front of each of the two sets of fixing blocks is provided with a U-shaped limiting rod. The opposite sides of the two sets of U-shaped limiting rods respectively abut against the inner walls of the left and right sides of the groove in the base plate.

[0011] Furthermore, anti-slip textures are provided on the adjacent sides of both sets of U-shaped limiting rods.

[0012] Furthermore, the positions of the upper surfaces of the two sets of U-shaped limiting rods and the upper surface of the base plate remain parallel.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. This utility model uses a starting motor to drive a screw, which in turn drives a slider to move a U-shaped fixing plate back and forth on the upper end of a base plate. Then, by pushing an L-shaped fixing plate, the slider moves back and forth within a groove on the base plate. This allows the grinder to move at multiple angles (front, back, left, right) within the groove on the base plate during subsequent grinding operations, thus completing the thorough grinding of the hinge. By keeping the lower surfaces of the two sets of casters parallel to the position of the upper surface of the hinge within the groove on the base plate, the lower surface of the grinder, when it abuts against the upper surface of the hinge, simultaneously drives one or both sets of casters to abut against the upper surface of the hinge. This minimizes vibration during grinding, improving the stability of the hinge and thus enhancing the practicality of the device.

[0015] 2. This utility model uses a vacuum cleaner to draw debris and dust generated during the polishing process of the hinge into the vacuum cleaner's interior via the suction pipe, thereby minimizing the inhalation of large amounts of dust by workers around the device and improving its hygiene. Furthermore, the support plate, mounted on the upper surface of the slider two, allows the subsequent polishing machine to move synchronously with the suction pipe and vacuum cleaner during adjustment. This enables the subsequent dust collection mechanism to adjust in sync with the polishing path of the machine, expanding its dust removal range and enhancing its practicality.

Therefore, they should not be construed as limitations on this utility model.

[0025] like Figures 1 to 4 As shown, a hinge grinding device includes a base plate 1. A groove is formed on the upper surface of the base plate 1, and an arc-shaped groove is formed at the bottom of the inner wall of the groove. A slot is formed on the upper surface of the base plate 1, and a grinding mechanism 2 for positioning the hinge during the grinding process is provided on the inner wall of the slot. A dust extraction mechanism 3 is provided on the upper surface of the grinding mechanism 2. A positioning slot is formed on the front of the base plate 1, and a positioning mechanism 4 is provided inside the positioning slot. Specifically, by keeping the lower surface of the grinding mechanism 2 parallel to the lower surface of the grinding equipment inside the grinding mechanism 2, the lower surface of the grinding mechanism 2 synchronously abuts against the upper surface of the hinge during the subsequent grinding process, thereby minimizing vibration of the hinge during grinding and improving the stability of the hinge during grinding. This enhances the practicality of the device.

[0026] like Figures 1 to 4As shown, the grinding mechanism 2 includes a slider 205, which is slidably connected to the slot in the base plate 1. An L-shaped fixing plate 203 is provided on the upper surface of the slider 205. A slot is formed on the upper surface of the L-shaped fixing plate 203. Through holes are formed on the inner walls of both the front and rear sides of the slot in the L-shaped fixing plate 203. A screw 206 is rotatably connected inside the two sets of through holes in the L-shaped fixing plate 203. A motor 204 is provided on the back of the L-shaped fixing plate 203. The output shaft of the motor 204 is mounted on the back of the screw 206. A slider 206 is threadedly connected to the external surface of the screw 206. 7. Slider 207 is slidably connected to the slot of L-shaped fixed plate 203. A U-shaped fixed plate 201 is provided on the lower surface of slider 207. Two sets of universal wheels 202 are installed on the lower surface of the U-shaped fixed plate 201. The lower surfaces of the two sets of universal wheels 202 abut against the upper surface of the base plate 1. The position of the lower surface of the two sets of universal wheels 202 is parallel to the position of the upper surface of the locking hinge inside the groove of the base plate 1. A grinder 208 is installed on the top of the inner wall of the U-shaped fixed plate 201. The position of the lower surface of the grinder 208 is parallel to the position of the lower surface of the two sets of universal wheels 202.

[0027] Specifically, when the hinge is engaged in the groove of the base plate 1, the starting motor 204 drives the screw 206 to push the slider 207, which in turn moves the U-shaped fixing plate 201 back and forth on the upper end of the base plate 1. Then, by pushing the L-shaped fixing plate 203, the slider 205 slides back and forth in the slot of the base plate 1. This allows the grinding machine 208 to move forward, backward, left, and right at multiple angles inside the groove of the base plate 1 when the grinding machine 208 is started, thus completing the full grinding of the hinge. By keeping the lower surfaces of the two sets of universal wheels 202 parallel to the position of the upper surface of the hinge engaged in the groove of the base plate 1, the lower surface of the grinding machine 208 abuts against the upper surface of the hinge, causing the lower surfaces of one or both sets of universal wheels 202 to simultaneously abut against the upper surface of the hinge. This minimizes vibration of the hinge during grinding, thereby improving the stability of the hinge during grinding and enhancing the practicality of the device.

[0028] like Figures 1 to 4 As shown, the vacuuming mechanism 3 includes a support plate 303, which is installed on the upper surface of the slider 207. A vacuum cleaner 301 is provided on the upper surface of the support plate 303. A vacuum cleaner pipe 302 is installed on the suction end of the vacuum cleaner 301. A through hole is opened on the upper surface of the U-shaped fixing plate 201. The suction end of the vacuum cleaner pipe 302 is snapped into the through hole of the U-shaped fixing plate 201. The suction end of the vacuum cleaner pipe 302 is located on one side of the grinder 208.

[0029] Specifically, by activating the vacuum cleaner 301, the debris and dust generated during the polishing process of the polishing mechanism 2 are sucked into the vacuum cleaner 301 along the suction pipe 302, thereby minimizing the inhalation of large amounts of dust by subsequent workers working around the device, thus improving the hygiene of the device during use. Furthermore, the support plate 303 is mounted on the upper surface of the slider 207, allowing the subsequent polishing machine 208 to move synchronously with the suction pipe 302 and the vacuum cleaner 301 during adjustment and movement. This enables the subsequent dust collection mechanism 3 to adjust synchronously along the polishing path of the polishing machine 208, thereby expanding the dust removal range of the subsequent dust collection mechanism 3 and improving the practicality of the device.

[0030] like Figure 1 and Figure 2 As shown, the positioning mechanism 4 includes a second motor 401 and a bidirectional screw 402. The inner walls of the positioning slots on both sides of the base plate 1 are provided with through holes. The bidirectional screw 402 is rotatably connected to the two sets of through holes in the base plate 1. The second motor 401 is installed on the right side of the base plate 1. The output shaft of the second motor 401 is installed on the right end of the bidirectional screw 402. The external threads of the bidirectional screw 402 are connected to two sets of fixing blocks 403. The front of each of the two sets of fixing blocks 403 is provided with a U-shaped limiting rod 404. The opposite sides of the two sets of U-shaped limiting rods 404 respectively abut against the inner walls of the grooves on the left and right sides of the base plate 1.

[0031] Specifically, by starting the motor 401, the bidirectional screw 402 is driven to rotate. During the rotation of the bidirectional screw 402, the two sets of fixing blocks 403 slide inside the positioning slots of the base plate 1. As the two sets of fixing blocks 403 slide, the adjacent sides of the two sets of U-shaped limiting rods 404 abut against the left and right sides of the hinge inside the groove of the base plate 1. This restricts the left and right movement of the hinge inside the groove of the base plate 1 by the positioning mechanism 4, thereby minimizing the movement of the hinge inside the groove of the base plate 1 during the grinding process. This improves the stability of the hinge during the grinding process.

[0032] like Figure 1 and Figure 2 As shown, anti-slip textures are provided on the adjacent sides of the two sets of U-shaped limiting rods 404. Specifically, the anti-slip textures are positioned between the two sets of U-shaped limiting rods 404 and the contact surfaces on both sides of the hinge. This increases the friction between the two sets of U-shaped limiting rods 404 and the outer surface of the hinge, thereby minimizing the possibility of the hinge sliding back and forth between the two sets of U-shaped limiting rods 404. This improves the stability of the two sets of U-shaped limiting rods 404 during the clamping and positioning of the hinge.

[0033] like Figure 1 and Figure 2As shown, the upper surfaces of the two sets of U-shaped limiting rods 404 are parallel to the upper surface of the base plate 1. Specifically, by keeping the upper surfaces of the two sets of U-shaped limiting rods 404 parallel to the upper surface of the base plate 1, and by keeping the lower surfaces of the two sets of casters 202 parallel to the upper surface of the hinge inside the groove of the base plate 1, the two sets of U-shaped limiting rods 404 can be kept as parallel as possible to avoid obstructing the normal movement of the two sets of casters 202 and the grinder 208 when the two sets of U-shaped limiting rods 404 are clamped on the left and right sides of the hinge inside the groove of the base plate 1.

[0034] In summary: By starting motor 204, the screw 206 drives slider 207, which in turn moves U-shaped fixing plate 201 back and forth on the upper end of base plate 1. Then, by pushing L-shaped fixing plate 203, slider 205 slides back and forth inside the slot of base plate 1. This allows the subsequent operation of the polishing machine 208, which moves at multiple angles (front, back, left, right) inside the groove of base plate 1, to complete the comprehensive polishing of the hinge. By starting the vacuum cleaner 301, the debris and dust generated during the polishing process are sucked into the vacuum cleaner 301 along the suction pipe 302, thus minimizing the inhalation of large amounts of dust by subsequent workers around the device.

[0035] Simultaneously, by starting motor 401, the bidirectional screw 402 is driven to rotate, causing the bidirectional screw 402 to drive the two sets of fixing blocks 403 to slide inside the positioning slots of the base plate 1 during rotation. This causes the two sets of fixing blocks 403 to drive the adjacent sides of the two sets of U-shaped limiting rods 404 to abut against the left and right sides of the hinge inside the groove of the base plate 1, thereby restricting the left and right movement of the hinge inside the groove of the base plate 1 by the positioning mechanism 4, thus minimizing the possibility of the hinge moving left and right inside the groove of the base plate 1 during the grinding process.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
