Description

Technical Field

[0002] Hardware is a metal workpiece made of iron, steel and other metals through physical processing such as forging, rolling, and cutting. After physical processing, there are burrs on the surface of hardware products. In order to improve the quality of the product, it is necessary to polish and grind it to make its surface smoother. During the grinding process, the hardware products need to be clamped and positioned. When the motor drives the grinding disc, grinding sheet, and grinding balls to rotate and grind the workpiece surface, the stability of the grinding operation can be guaranteed.

[0003] In the actual polishing process of existing hardware products, most of them use rotatable positioning fixtures to clamp and fix the hardware products on the positioning fixtures. During the polishing process, the servo motor drives the positioning fixtures to rotate, which facilitates the flipping of the hardware products and ensures that most areas of the hardware products can be polished. No manual adjustment is required during the polishing operation, making the actual operation stage more convenient.

[0004] However, in actual operation, the hardware products are usually clamped and positioned at one or both ends. When one end is clamped, if the grinding tool grinds the part of the hardware product away from the clamping end, the probability of the part being subjected to force and deforming will increase. When both ends are clamped, when the grinding tool grinds the middle suspended part of the hardware product, the probability of the suspended part being deformed will increase, which significantly reduces the qualified rate of the hardware products. Therefore, the present application proposes a rotatable hardware product grinding and positioning bracket that can stably clamp the hardware products and reduce the probability of their deformation.

[0032] The top of the above-mentioned base 1 is fixedly installed with a slide 3, and the top of the slide 3 is slidably installed with a slide table 31, and the top of the slide table 31 is rotatably installed with a longitudinal adjustment screw 33, and longitudinal limit plates 32 are provided on both sides of the longitudinal adjustment screw 33. The bottom of the above-mentioned longitudinal limit plates 32 is fixed to the upper surface of the slide table 31, and a connecting plate 51 is movably installed on the above-mentioned two longitudinal limit plates 32. The top of the longitudinal adjustment screw 33 passes through the threaded hole drilled on the connecting plate 51 and is threadedly connected to it. When the longitudinal adjustment screw 33 rotates, it can drive the connecting plate 51 to move up and down; the above-mentioned connecting plate A number of support rods 52 are fixedly installed on the upper surface of the plate 51, and a support plate 53 is fixedly installed on the top of the support rods 52. A rubber gasket 54 is fixedly installed on the upper surface of the support plate 53. The above-mentioned connecting plate 51, support rods 52, support plate 53 and rubber gasket 54 together constitute the bracket 5. After the hardware workpiece 7 is fixed, the height of the bracket 5 is adjusted so that the bottom of the hardware workpiece 7 overlaps the upper surface of the rubber gasket 54, which can support the part of the hardware workpiece 7 away from the clamping end. When the grinding tool applies pressure to the hardware workpiece 7, the probability of deformation of the hardware workpiece 7 can be reduced.

[0033] Furthermore, a screw frame plate 36 is fixedly assembled on the top of the slide 3, and a transverse adjustment screw 4 is rotatably installed on the screw frame plate 36. One end of the transverse adjustment screw 4 passes through the slide 31 and is threadedly connected to it. The slider fixedly installed at the bottom of the slide 31 is embedded in the slide groove on the top of the slide 3 and is slidably connected to it. When the transverse adjustment screw 4 rotates, it can drive the slide 31 and the bracket 5 to move laterally, which is convenient for adjusting the horizontal position of the bracket 5; a limiting sleeve 21 is fixedly installed on the support plate 2, and the end of the transverse adjustment screw 4 away from the screw frame plate 36 is inserted into the limiting sleeve 21 and rotatably connected to it.

Since the first circular gear 34 and the second circular gear 35 are meshed and connected, when the above-mentioned rotating rod is rotated, the longitudinal adjustment screw 33 can be driven to rotate. A driving motor can also be set up above the rotating rod, so that the output shaft of the driving motor is fixedly connected to the rotating rod, and the rotating rod is driven to rotate by the driving motor, replacing the manual adjustment knob, which can be replaced according to actual conditions.

[0035] Furthermore, the clamping screw 86 is rotatably installed with a clamping block 84 at one end near the hardware workpiece 7.
