Description

Technical Field

[0001] The utility model relates to the technical field of hardware polishing devices, in particular to a tubular hardware polishing device. Background Art

[0002] Hardware refers to parts made of metals such as iron and steel through physical processing methods such as forging, stamping, and cutting. After physical processing, burrs will appear on the surface of the hardware, which needs to be polished and ground. This is especially true for tubular hardware, which not only has burrs on the outer wall, but also on the inner wall. The treatment of burrs on the outer wall of tubular hardware is relatively simple. Due to the limited space on the inner wall of the pipe, the operation difficulty of treating the burrs on the inner wall is greater than the difficulty of treating the burrs on the outer wall of the pipe. Therefore, mechanical equipment is needed to polish it.

[0003] In the existing tubular hardware grinding process, a grinding roller is usually fixedly installed at the output end of the motor, and the motor drives the grinding roller to rotate. The diameter of the grinding roller must be smaller than the inner diameter of the pipe, and a gap must be ensured between the two to allow the grinding debris to fall out. During the rotation of the grinding roller, the grinding roller also needs to rotate along the inner wall of the pipe to fully grind the inner wall of the pipe, thereby replacing manual handheld grinding tools to operate, effectively improving the efficiency of the grinding operation, and reducing the labor intensity of the staff.

[0004] However, in actual operation, in order for the grinding roller to fully grind the inner wall of the pipe, the motor needs to rotate along the inner wall of the pipe, so as to ensure that the grinding roller grinds around the inner wall of the pipe. When the grinding roller rotates at high speed, the grinding roller contacts the inner wall of the pipe and generates an interaction force. If the grinding roller needs to move while keeping rotating, it is easy to cause the connection between the grinding roller and the output end of the motor to loosen and be damaged, which significantly increases the probability of failure. Therefore, the present application proposes a tubular hardware grinding device that can prevent the grinding roller from loosening or being damaged during rotation. Utility Model Content

[0005] The purpose of the utility model is to address the problem in the background technology that the connection between the grinding roller and the motor output end is prone to loosening or damage under high-speed rotation, and to propose a tubular hardware grinding device that can prevent the grinding roller from loosening or being damaged when rotating.

[0027] The technical solution of the present invention is further described below with reference to the accompanying drawings and specific embodiments.

[0028] Example

[0029] like Figure 1-Figure 5As shown, the present invention proposes a tubular hardware polishing device, including a base 1, a motor 2 is fixedly installed on the top of the base 1, a connecting seat 61 is fixedly installed on the output end of the motor 2, a plurality of positioning support plates 63 are fixedly installed on the top of the connecting seat 61 by screws, and a polishing roller 64 is fixedly installed on the top of the positioning support plate 63. The above-mentioned connecting seat 61, positioning support plates 63 and polishing rollers 64 together constitute a polishing assembly 6, which is driven to rotate by the motor 2, and then the polishing roller 64 can be driven to rotate rapidly, ensuring that the polishing assembly 6 can polish the inner wall of the hardware tube 7; a support plate 3 is fixedly installed on the top of the base 1 through a bracket, and the support plate 3 is mounted above the motor 2, and the connecting seat 61 is set in a circular opening cut on the support plate 3. Inside; a first clamping seat 4 is fixedly installed on the top of the above-mentioned support plate 3, and a second clamping seat 5 is fixedly installed above the support plate 3 through a bracket. The bottom end of the hardware tube 7 is inserted into the first clamping seat 4 and clamped and fixed, and then the second clamping seat 5 clamps and fixes the top outer wall of the hardware tube 7 to ensure that the hardware tube 7 does not rotate during the grinding process. A plurality of small-diameter grinding rollers 64 are used to replace the traditional large-diameter roller body, which not only reserves enough space between the hardware tube 7 and the grinding roller 64 to ensure that the polished debris can fall out, but also the grinding roller 64 is fixed on the connecting seat 61, and is not directly fixed on the output end of the motor 2. Therefore, when the grinding roller 64 performs a circular motion, it will not affect the firmness of the connection between the connecting seat 61 and the output end of the motor 2.

[0030] Furthermore, a plurality of slots 62 are carved on the top of the connecting seat 61, and one end of the positioning support plate 63 is embedded in the slot 62 and engaged with it, and then the positioning support plate 63 is fixed to the connecting seat 61 with screws to ensure that the grinding roller 64 can be firmly installed on the connecting seat 61; by removing the screws used to fix the positioning support plate 63, the grinding roller 64 can be removed, making it convenient to replace the grinding roller 64.

[0031] Secondly, a circular groove 41 is carved at the top of the first clamping seat 4, and the bottom end of the hardware tube 7 is inserted into the circular groove 41. A plurality of positioning screws 42 are threadedly installed on the first clamping seat 4. One end of the positioning screw 42 extends into the circular groove 41 and is fixedly installed with a rubber column head 43. The positioning screw 42 is rotated into the circular groove 41. When the above-mentioned multiple rubber column heads 43 are in close contact with the outer wall of the bottom of the hardware tube 7, the bottom of the hardware tube 7 can be clamped and fixed, ensuring that the bottom of the hardware tube 7 can be stably installed on the first clamping seat 4.

[0032] Furthermore, two symmetrically arranged clamping plates 51 are movably mounted on the second clamping seat 5, and the clamping plates 51 are mounted on the inner side of the elongated opening excavated on the second clamping seat 5, and side openings communicating with the above-mentioned elongated openings are excavated on both sides of the second clamping seat 5, and a connecting plate 52 is movably mounted in the side opening, and one end of the connecting plate 52 is fixedly connected to the clamping plate 51 to ensure that the clamping plate 51 can be stably and movably mounted on the second clamping seat 5; a rubber pad 53 is fixedly mounted on the inner wall of the clamping plate 51, pushing the clamping plate 51 toward the side of the hardware tube 7. When the rubber pad 53 is in close contact with the outer wall of the hardware tube 7, the hardware tube 7 can be stably clamped, effectively preventing the top of the hardware tube 7 from shaking.

[0033] It is worth noting that two frame plates 54 are fixedly installed on the two outer side walls away from each other of the above-mentioned second clamping seat 5, and a straight rod 55 is fixedly installed between the two frame plates 54 arranged on the same side. The straight rod 55 passes through the circular through-hole excavated on the connecting plate 52 and is movably connected thereto, ensuring that the connecting plate 52 can move stably laterally along the straight rod 55, effectively improving the stability of the clamping plate 51 during lateral adjustment; the above-mentioned straight rod 55 is provided with a threaded portion, and a limiting nut 56 is threadedly installed on the threaded portion. When the clamping plate 51 is in close contact with the hardware tube 7, the limiting nut 56 is rotated and made to be in close contact with the outer wall of the connecting plate 52, and then the connecting plate 52 can be limited to prevent the clamping plate 51 from being displaced, thereby effectively improving the firmness of the clamping and positioning of the top of the hardware tube 7.

[0034] In this embodiment, first, the bottom of the hardware tube 7 is inserted into the circular groove 41 carved on the top of the first clamping seat 4, and the positioning screw 42 is rotated toward the inside of the circular groove 41. When the rubber column head 43 fixedly installed at the end of the positioning screw 42 is in close contact with the outer wall of the hardware tube 7, the bottom of the hardware tube 7 can be clamped and fixed; then, the top of the hardware tube 7 is clamped and fixed, and the clamping plate 51 is pushed toward one side of the hardware tube 7. When the rubber pad 53 is in close contact with the outer wall of the hardware tube 7, the connecting plate 52 can be limited by the limiting nut 56 installed on the straight rod 55 to prevent the clamping plate 51 from moving, thereby ensuring that the top of the hardware tube 7 can be firmly clamped between the two clamping plates 51, thereby effectively improving the stability of the hardware tube 7 during the grinding process.

[0035] When the clamping and positioning of the hardware tube 7 is completed, the motor 2 drives the connecting seat 61 to rotate, and then drives the multiple grinding rollers 64 to rotate rapidly along the inner wall of the hardware tube 7, which can effectively grind the inner wall of the hardware tube 7; using multiple small-diameter grinding rollers 64 to replace the traditional large-diameter roller body, not only can sufficient space be left between the grinding rollers 64 and the hardware tube 7 so that the debris generated during grinding can fall out, but the grinding rollers 64 are fixed on the connecting seat 61, not directly fixed on the output shaft of the motor 2. Therefore, when the motor 2 drives the connecting seat 61 to rotate rapidly, the multiple grinding rollers 64 replace the traditional fixed-axis rotation method with a circular motion, which can fully grind the inner wall of the hardware tube 7 without affecting the firmness of the connection between the grinding rollers 64 and the motor 2, effectively reducing the probability of failure.

[0036] The above specific embodiments are merely several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant inspirations of the above embodiments, those skilled in the art may make various alternative improvements and combinations to the above specific embodiments.
