Technical Field

[0001] The utility model relates to the technical field of hardware processing, in particular to an end face grinding device for hardware production. Background Art

[0002] Hardware refers to tools made of gold, silver, copper, iron, tin and other metals through processing and casting. They are often used to connect and fix different materials or components, and can also be used to add beauty and decorative effects. During the processing of hardware, the end faces need to be polished to remove burrs on the surface of the hardware, make its surface smooth, and improve the quality, precision and aesthetics of the hardware.

[0003] The existing Chinese patent announcement number is: CN220217756U, which discloses a hardware end face grinding device, including a base, a grinder is arranged at the top of the base, a support block is fixedly connected to the top end of the base away from the grinder, a threaded rod is passed through and rotatably connected to the left side of the support block, a protrusion is threadedly connected to the outer wall of the threaded rod, a connecting block is hingedly connected to the front surface of the protrusion, and a clamping block is hingedly connected to the right side of the connecting block. The utility model clamps the rectangular workpiece by the clamping block, and after the surface of the rectangular workpiece is polished by the grinder, the limit block is pulled upward to contact the limit of the protrusion and then the threaded rod is rotated to flip the clamping block, so that the bottom end of the rectangular workpiece can be directly facing upward, and it is no need to take down the rectangular workpiece, flip it, and then fix it for polishing, which reduces the operation time and improves the processing efficiency.

[0004] In this patent, when it is necessary to grind the other end face of the hardware, it is necessary to pull the limit block upward to release the limit on the protrusion, and then rotate the threaded rod to flip the clamping block to the other end face of the hardware facing upward, so as to grind the other end face of the hardware. However, the flipping of the hardware is achieved by manually rotating the threaded rod, and it is difficult to rotate the threaded rod to a precise angle, resulting in the end face of the hardware being prone to tilt after flipping, or the threaded rod needs to be rotated again to adjust the position of the hardware, thereby reducing the efficiency of grinding the end face of the hardware.

[0025] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0026] Figure 1-3 As one embodiment of the utility model, a hardware production end surface grinding device comprises a base 1, a grinding unit 2 is provided on the upper surface of the base 1, and a positioning mechanism 3 for clamping the hardware is provided on the side of the grinding unit 2;

[0027] The positioning mechanism 3 includes a support plate 31 slidably connected to the upper surface of the base 1, and a connecting plate 32 is rotatably connected to the side of the support plate 31 facing the grinding unit 2, and fixing rods 33 are slidably connected to both sides of the connecting plate 32, and a clamping block 34 is fixed to the end of the fixing rod 33 for clamping and positioning the hardware;

[0028] The positioning mechanism 3 further includes a driving component 35 for moving the fixing rod 33 and a flipping component for controlling the connection plate 32 to rotate.

[0029] In actual use, when grinding the end face of the hardware, the hardware is placed between the two clamping blocks 34, and the two fixing rods 33 are moved toward each other by controlling the driving component 35. The clamping block 34 is driven by the fixing rod 33 to approach the hardware. When the clamping block 34 contacts the hardware, the clamping and positioning of the hardware is achieved, and the grinding unit 2 is used to grind the upward end face of the hardware. When it is necessary to grind the other end face of the hardware, the flipping component is used to rotate the connecting plate 32, and the connecting plate 32 is controlled to rotate 180 degrees, so that the clamped hardware rotates 180 degrees. At this time, the other end face of the hardware rotates to face upward, thereby achieving rapid grinding of the two end faces of the hardware and improving the grinding efficiency of the hardware.

[0030] More specifically, the driving component 35 includes a motor 351 fixed in the inner cavity of the connecting plate 32, a gear 352 is fixed to the output end of the motor 351, a rack 353 meshing with the gear 352 is provided on the fixing rod 33, and two fixing rods 33 are respectively arranged on the upper and lower sides of the gear 352.

[0031] In actual use, when it is necessary to clamp and position the hardware, the motor 351 is controlled to rotate the gear 352. Since the two racks 353 are distributed on the upper and lower sides of the gear 352, the rotation of the gear 352 drives the racks 353 on the upper and lower sides to move in opposite directions, thereby causing the two fixing rods 33 to move, driving the clamping block 34 to approach the hardware, thereby achieving the clamping and positioning of the hardware.

[0032] More specifically, the turning component includes a rotating cylinder 36 fixed to the side of the supporting plate 31 , and the output end of the rotating cylinder 36 passes through the supporting plate 31 and is fixedly connected to the connecting plate 32 .

[0033] In actual use, when it is necessary to grind the other end face of the hardware, the rotating cylinder 36 is controlled to rotate the connecting plate 32. The model of the rotating cylinder 36 is MSQB10A. The rotating cylinder 36 can rotate 180 degrees, thereby driving the clamped hardware to rotate 180 degrees, so that the other end face of the hardware faces upward, which is convenient for grinding the other end face of the hardware and improving the grinding efficiency of the end face of the hardware.

[0034] More specifically, a V-shaped groove 37 is provided on the clamping block 34, and a rubber pad 38 is fixed on the inner wall of the V-shaped groove 37 to protect the surface of the hardware. In actual use, when the clamping block 34 is used to clamp and fix the hardware, the V-shaped groove 37 is provided on the clamping block 34 to expand the contact area between the clamping block 34 and the hardware, and the rubber pad 38 is provided to make the hardware more stable when clamped and fixed, thereby improving the polishing effect of the end face of the hardware.

[0035] Specifically, a material drop chute 4 is provided on the upper surface of the base 1 , and the front cross-section of the material drop chute 4 is a trapezoid that is wide at the top and narrow at the bottom, and a filter screen 5 is fixed at the bottom of the material drop chute 4 for filtering debris.

[0036] In actual use, during the grinding process of hardware, coolant is needed to reduce the temperature of the hardware surface and rinse the iron filings impurities on the hardware surface and the mold. By setting a sloped blanking trough 4 on the base 1, the coolant containing iron filings impurities can flow along the wall of the blanking trough 4 to the filter 5. The filter 5 filters the iron filings in the coolant and leaves them on the filter 5, which is convenient for recycling the coolant.

[0037] More specifically, a conduit 6 is fixed to the bottom of the filter screen 5 , the end of the conduit 6 passes through the side of the base 1 and is connected to a valve 7 for collecting the coolant.

[0038] In actual use, after the iron filings impurities are filtered out by the filter 5, the filtered coolant flows into the conduit 6 along the filter 5. When the coolant needs to be recovered, the pipeline can be connected to the end of the conduit 6 or a recovery bucket can be placed under the end of the conduit 6. After opening the valve 7, the coolant flows into the recovery bucket along the conduit 6, thereby improving the efficiency of processing the recovered coolant and reducing the labor intensity of the staff.
