Description

Technical Field

[0001] The utility model relates to the technical field of burr removal of hardware parts, in particular to a burr removal device for hardware stamping parts. Background Technique

[0002] Hardware: Traditional hardware products, also known as "small hardware", refer to five metals, namely gold, silver, copper, iron, and tin. Through manual processing, they can be made into artworks such as knives and swords or metal devices. In modern society, hardware is more extensive. For example, hardware tools, hardware parts, daily hardware, building hardware, and security products, etc. Most small hardware products are not final consumer goods, and grinding devices are needed during the processing of pipe fittings and hardware parts.

[0003] As the Chinese patent authorization announcement number CN212683542U provides a metal pipe polishing device, including a bottom plate, a support column A, a support column B, and a cross beam. A motor base is provided on one side of the support column A. A second motor is fixedly connected to the motor base. After the output shaft of the second motor passes through the support column A, it is movably connected to the support column A through a bearing. The end of the output shaft of the second motor is fixedly connected to a third hydraulic telescopic device. The telescopic end of the third hydraulic telescopic device is fixedly connected to a clamping device A. The support column B is movably connected to a rotating shaft through a bearing. The rotating shaft is movably connected to the support column B through a bearing. The end of the rotating shaft is fixedly connected to a clamping device B. This utility model clamps a metal pipe between the clamping device A and the clamping device B, realizing the rotation of the output shaft of the second motor, the metal pipe, and the rotating shaft on the same horizontal line, thereby realizing multi-directional polishing of the metal pipe and effectively improving the polishing efficiency;

[0004] By checking the above comparison documents, it can be seen that the prior art still has the following deficiencies. During the process of removing burrs on the surface of hardware pipe fittings, it is often necessary to clamp and fix the pipe fittings through a clamping structure. However, during the clamping process of the hardware pipe fittings, it is necessary to align the hardware pipe fittings. If the hardware pipe fittings are not aligned or even skewed, the hardware pipe fittings will rotate eccentrically, affecting the quality of deburring processing. Moreover, when the hardware pipe fittings are clamped and fixed, the clamped parts on the surface of the hardware pipe fittings are blocked, and it is easy to have dead corners for deburring, so that the deburring work is not comprehensive enough. Content of the Utility Model

[0005] The utility model provides a burr removal device for hardware stamping parts, which is conducive to conveniently aligning and positioning the hardware pipe fittings and ensuring the comprehensiveness of the deburring work.

[0011] Further, the frustum-shaped support block and the frustum-shaped pressing block are symmetrically distributed up and down.

[0012] Further, balls are rotatably connected to the ends of the frustum-shaped positioning blocks.

[0013] Further, the first lifting driving assembly includes a first reversible motor, a first lead screw, and a pressing plate. The first reversible motor is fixed to the right side of the top end inside the frame. One end of the first lead screw is connected to the power end of the first reversible motor, and the other end of the first lead screw is rotatably connected to the bottom end inside the frame.

Then, through the cooperation of the frustum pressing block and the frustum supporting block, the upper and lower ends of the hardware pipe fittings are clamped and fixed, effectively preventing the hardware pipe fittings from eccentric rotation during rotary grinding and deburring, which is conducive to ensuring the quality of the hardware pipe fittings during deburring processing.

Detailed Embodiment

[0026] For the convenience of understanding by those skilled in the art, the present utility model will be further described below in conjunction with the embodiments and the drawings. The content mentioned in the embodiments does not limit the present utility model.

[0027] Such as Figures 1-5As shown in the figure, in this embodiment, it includes a frame 1. At the bottom end inside the frame 1, a first driving motor 2 is fixed. The power end of the first driving motor 2 is connected to a frustum support block 3. Above the frustum support block 3, there is a frustum pressing block 18. The upper end of the frustum pressing block 18 is rotatably connected to a pressing rod 17. On the right side of the pressing rod 17, there is a first lifting driving assembly. The first lifting driving assembly includes a first reversible motor 12, a first lead screw 13, and a pressing plate 16. The first reversible motor 12 is fixed on the right side of the top end inside the frame 1. One end of the first lead screw 13 is connected to the power end of the first reversible motor 12, and the other end of the first lead screw 13 is rotatably connected to the bottom end inside the frame 1. The pressing plate 16 is slidably connected to the right inner wall of the frame 1, and the pressing plate 16 is threadedly sleeved on the first lead screw 13. The pressing rod 17 is fixed to the left end of the pressing plate 16. Between the frustum support block 3 and the frustum pressing block 18, there is an annular cover 4. The inner wall of the annular cover 4 is connected with a number of evenly distributed spring return rods 5. The ends of the spring return rods 5 are all fixed with frustum positioning blocks 6. The frustum support block 3 and the frustum pressing block 18 are symmetrically distributed up and down. The ends of the frustum positioning blocks 6 are all rotatably connected with balls 7.

[0028] When removing the burrs on the surface of the hardware pipe fittings through this burr removal device, the hardware pipe fittings are inserted into the annular cover 4 from top to bottom. During this process, the hardware pipe fittings push the frustum positioning blocks 6 outwards along the inclined surfaces of the frustum positioning blocks 6. The frustum positioning blocks 6 will compress the spring return rods 5. At the same time, the balls 7 will roll along the surface of the hardware pipe fittings, which is beneficial to ensuring the smoothness of the up and down movement of the hardware pipe fittings. Then, through the cooperation of multiple spring return rods 5 and frustum positioning blocks 6, the spring return rods 5 drive the balls 7 on the frustum positioning blocks 6 to clamp around the hardware pipe fittings through the elastic force, which is beneficial to quickly positioning and aligning the hardware pipe fittings. Then, the first reversible motor 12 drives the first lead screw 13 to rotate, and the first lead screw 13 drives the pressing plate 16 to slide down along the frame 1. At this time, the pressing plate 16 will drive the pressing rod 17 and the frustum pressing block 18 to move down until the frustum pressing block 18 presses on the upper end of the hardware pipe fittings. Therefore, the cooperation of the frustum pressing block 18 and the frustum support block 3 clamps and fixes the upper and lower ends of the hardware pipe fittings. When the first driving motor 2 drives the frustum support block 3, the hardware pipe fittings, and the frustum pressing block 18 to rotate, it effectively prevents the hardware pipe fittings from generating eccentric rotation during the rotary grinding and deburring process, which is beneficial to ensuring the quality of the deburring processing of the hardware pipe fittings.

[0029] As Figure 4As shown in the figure, in this embodiment, synchronous cylinders 8 are fixedly installed at both the upper and lower ends of the inner sidewall of the annular cover 4. The power end of the synchronous cylinder 8 is connected to a second driving motor 9, and the power end of the second driving motor 9 is connected to a grinding disc 10. A second lifting driving assembly is arranged on the left side of the annular cover 4. The second lifting driving assembly includes a second forward and reverse motor 14, a second lead screw 15, and a lifting plate 11. The second forward and reverse motor 14 is fixedly installed on the left side of the inner top end of the frame 1. One end of the second lead screw 15 is connected to the power end of the second forward and reverse motor 14, and the other end of the second lead screw 15 is rotatably connected to the inner bottom end of the frame 1. The lifting plate 11 is slidably connected to the left inner wall of the frame 1 and is threadedly sleeved with the second lead screw 15. The annular cover 4 is fixedly connected to the lifting plate 11.

[0030] After the metal hardware fittings are clamped and fixed up and down, the synchronous cylinder 8 works to drive the grinding disc 10 to approach the surface of the metal hardware fittings until the grinding disc 10 can deburr and polish the surface of the metal hardware fittings. On the premise that the metal hardware fittings rotate and the second driving motor 9 drives the grinding disc 10 to rotate, at the same time, the second forward and reverse motor 14 works to drive the second lead screw 15 to rotate, and the second lead screw 15 will drive the lifting plate 11, the annular cover 4, and the grinding disc 10 to move upward. Therefore, when the grinding disc 10 moves upward, it will deburr and polish the rotating metal hardware fittings, and the surface of the metal hardware fittings is not blocked, avoiding dead corners in deburring. Therefore, through the cooperative work of the two grinding discs 10, it is beneficial to comprehensively grind and remove the burrs on the surface of the metal hardware fittings.

[0031] All the technical features in this embodiment can be freely combined according to actual needs.

[0032] The above embodiment is a preferred implementation solution of the present invention. In addition, there are other implementation methods. Any obvious replacement without departing from the concept of the technical solution of the present invention is within the protection scope of the present invention.
