Description

Technical Field

[0001] The utility model relates to the technical field of copper tube processing, in particular to a copper tube double-sided grinding device. Background Art

[0002] Copper pipes (also known as red copper pipes) are commonly used in water pipes, heating and cooling pipes, and can be used in a variety of environments. Combining the advantages of both metal and non-metallic pipes, copper pipes dominate hot and cold water systems and are the best connecting pipes. They are fire-resistant and heat-resistant, maintaining their shape and strength even at high temperatures without aging.

[0003] In order to make the surface of the copper tube reach the required smoothness, the copper tube needs to be polished during the production and manufacturing process, that is, the copper tube surface is polished by a copper tube polishing device;

[0004] Since the copper tube has a multi-faceted structure inside and outside, and the smoothness of the inner surface of the copper tube needs to be consistent with that of the outer surface, it is necessary to polish both the inside and the outside of the copper tube during the polishing work. However, most traditional copper tube polishing equipment can only complete the polishing process of the outer surface of the copper tube, and it is not convenient to polish the inner surface of the copper tube. At this time, manual internal polishing operations are required, but manual polishing greatly reduces the polishing rate of the inner surface of the copper tube, reduces the production efficiency of the copper tube, and increases labor cost investment. For this reason, the utility model proposes a copper tube double-sided polishing equipment. Utility Model Content

[0005] The purpose of the utility model is to provide a copper tube double-sided grinding device to solve the problems raised in the above background technology.

[0010] Preferably, a plurality of reflective warning strips with equal spacing and linear distribution are attached to the upper surface of the grinding seat by glue.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] The utility model can complete the internal and external synchronous grinding work of the copper tube at the same time within the same processing time, and has the characteristic of internal and external double-sided synchronous grinding, thereby effectively avoiding manual grinding of the inner wall of the copper tube, effectively improving the double-sided grinding effect and grinding efficiency of the copper tube, and improving the overall production speed of the copper tube. In addition, the operation by replacing manual labor with machinery can effectively reduce labor cost investment and improve the internal and external grinding effect of the copper tube.

[0022] See also Figure 1-4 The utility model provides an embodiment of a copper tube double-sided grinding device, comprising a grinding seat 1. In order to play a better warning role, a plurality of reflective warning strips with equal intervals and linear distribution are attached to the upper surface of the grinding seat 1 by glue. A first-level fixing seat 2 is fixedly installed on one side of the upper surface of the grinding seat 1 by fixing bolts, and a second-level fixing seat 5 is fixedly installed on the other side of the upper surface of the grinding seat 1. A driving cylinder 6 is fixedly installed on the side outer wall of the second-level fixing seat 5 by fixing bolts. The output end of the driving cylinder 6 is telescopically connected with a telescopic rod 7. The top of the telescopic rod 7 is fixedly connected to a mounting seat 12. A grinding sleeve 8 is fixedly installed on the mounting seat 12 by fixing bolts. A circular inner groove 9 is provided inside the grinding sleeve 8. An outer grinding sheet 10 is fixedly installed on the outer wall of the top end of the inner groove 9, and an inner grinding sheet 11 is fixedly installed on the outer wall below the inner groove 9. Therefore, in actual use, the outer grinding sheet 10 can contact the outer surface of the copper tube, and the inner grinding sheet 11 can contact the inner surface of the copper tube.

[0023] In order to clamp the end of the copper tube, a rotating motor 3 is fixedly installed on the outer wall of one side of the first-level fixing seat 2 by fixing bolts, and a three-jaw chuck 4 is fixedly installed on the output shaft of the rotating motor 3;

[0024] According to the above structure, when it is necessary to perform double-sided grinding on the copper tube, one end of the copper tube that matches the diameter of the inner groove 9 of the utility model can be fixed to one side of the equipment through the three-jaw chuck 4, so as to achieve the effect of fixing the end;

[0025] After the copper tube adapted to the processing size of the utility model is fixed, the driving cylinder 6 can be used to work. When the driving cylinder 6 is working, it drives the telescopic rod 7 to extend. When the telescopic rod 7 is extended, it drives the polishing sleeve 8 at the top to move toward the side of the three-jaw chuck 4, so that the inner groove 9 of the polishing sleeve 8 can be integrally sleeved on the outside of the copper tube;

[0026] When the polishing sleeve 8 is sleeved on the outside of the copper tube through the inner groove 9, the outer polishing sheet 10 arranged inside the inner groove 9 can contact the outer surface of the copper tube, and the inner polishing sheet 11 can contact the inner surface of the copper tube;

[0027] At this time, the rotating motor 3 can be rotated. When the rotating motor 3 rotates, it drives the copper tube clamped at the top to rotate as a whole. When the copper tube rotates, the outer grinding disc 10 and the inner grinding disc 11 can cooperate with the rotating copper tube to grind the inside and outside at the same time, thereby achieving a double-sided grinding effect on the copper tube.

[0028] Through the coordinated use of the above-mentioned structure, the utility model can simultaneously complete the internal and external synchronous grinding of the copper tube within the same processing time, and has the characteristics of internal and external double-sided synchronous grinding, thereby effectively avoiding manual grinding of the inner wall of the copper tube, effectively improving the double-sided grinding effect and grinding efficiency of the copper tube, and improving the overall production speed of the copper tube. In addition, the operation by replacing manual labor with machinery can effectively reduce labor cost investment and improve the internal and external grinding effect of the copper tube.

[0029] In this embodiment, in order to improve the bottom support effect and processing stability of the grinding seat 1, a lower bracket 13 is fixedly installed on the lower surface of the bottom end of the grinding seat 1, and a plurality of evenly distributed lower pillars 14 are fixedly installed on the lower surface of the bottom end of the lower bracket 13;

[0030] Furthermore, a support base 15 is fixedly installed between the bottom ends of the lower pillars 14, and a plurality of reinforcing columns are fixedly installed on the inner wall on the opposite side of the support base 15 by welding, and the plurality of reinforcing columns are linearly distributed with equal intervals.

[0031] Working principle: When double-sided grinding of a copper tube is required, one end of the copper tube that matches the diameter of the inner groove 9 of the utility model can be fixed to one side of the equipment through the three-jaw chuck 4, thereby achieving the effect of fixing the end;

[0032] After the copper tube adapted to the processing size of the utility model is fixed, the driving cylinder 6 can be used to work. When the driving cylinder 6 is working, it drives the telescopic rod 7 to extend. When the telescopic rod 7 is extended, it drives the polishing sleeve 8 at the top to move toward the side of the three-jaw chuck 4, so that the inner groove 9 of the polishing sleeve 8 can be integrally sleeved on the outside of the copper tube;

[0033] When the polishing sleeve 8 is sleeved on the outside of the copper tube through the inner groove 9, the outer polishing sheet 10 arranged inside the inner groove 9 can contact the outer surface of the copper tube, and the inner polishing sheet 11 can contact the inner surface of the copper tube;

[0034] At this time, the rotating motor 3 can be rotated. When the rotating motor 3 rotates, it drives the copper tube clamped at the top to rotate as a whole. When the copper tube rotates, the outer grinding disc 10 and the inner grinding disc 11 can cooperate with the rotating copper tube to grind the inside and outside at the same time, thereby achieving a double-sided grinding effect on the copper tube.

[0035] At the same time, when performing rotary grinding, the driving cylinder 6 can drive the telescopic rod 7 to perform a short distance reciprocating telescopic motion, so that the grinding sleeve 8 can have a left and right linear displacement effect. When the grinding sleeve 8 is displaced left and right, the linear friction grinding of the copper tube can be completed. By coordinating the technical characteristics of rotary grinding, the grinding equipment of the utility model can simultaneously have the dual grinding effects of rotation and linear displacement, effectively improving the internal and external grinding quality of the copper tube;

[0036] The overall length of the grinding sleeve 8 can be dynamically increased or decreased according to different production requirements and the distance between the grinding sleeve and the three-jaw chuck 4;

[0037] When the copper tube to be polished is too long, the polishing sleeve 8 cannot completely wrap and polish the copper tube. At this time, one end of the copper tube can be polished first. After polishing one end, the copper tube can be loosened by the three-jaw chuck 4, and then the positions of the two ends of the copper tube can be swapped. After that, the other end can be wrapped and polished inside and outside, so that the synchronous polishing effect of the longer copper tube can be completed.

[0038] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
