Description

Technical Field

[0001] The utility model relates to the technical field of bushing processing, in particular to a scraping and coating tool. Background Art

[0002] The bushing is a matching part used outside the mechanical parts to achieve the functions of sealing, wear protection, etc., and refers to a ring sleeve that acts as a liner. During the processing of the bushing, it is necessary to coat the inner wall of the bushing with resin. For example, Chinese patent CN202539028U discloses a bushing inner wall glue coating device, including a fixed bracket and a feeding part and a coating part installed on the fixed bracket, the feeding part includes a rotatable glue coating roller, and a scraper arranged on one side of the glue coating roller, and the coating part includes two rotatable rollers. When in use, first brush the glue on the glue coating roller of the feeding part, and during the rotation of the glue coating roller, the scraper evenly distributes the glue on the glue coating roller and scrapes away the excess glue, and then a roller brush is placed on the glue coating roller to transfer the glue to the roller brush, and the bushing pipe fitting is placed on the roller brush and placed between the two rollers. The motor drives the roller, bushing and roller brush to roll together, and the glue can be evenly brushed on the inner wall of the bushing. However, this device cannot ensure that there is no material residue on the coating surface of the bushing. Furthermore, the device cannot be placed sideways, and the fluid resin will drip and accumulate on the fixed bracket. Utility Model Content

[0014] The following is a further detailed description of the specific embodiments of the present invention. It should be understood that the description of the embodiments of the present invention herein is not intended to limit the protection scope of the present invention.

[0015] like Figure 1 As shown, it is a schematic diagram of the structure of the scraping tool provided by the utility model. The scraping tool includes a base 10 and a scraper assembly 20 rotatably arranged on the base 10. It can be imagined that the scraping tool also includes some other functional modules, such as a coating module, a heating module, etc., which are technologies well known to those skilled in the art and will not be described one by one here.

[0016] It should be noted that the coating tool evenly coats the resin on the circumferential inner wall of a bushing 30. The tool can be used not only to coat the bushing 30, but also to coat the inner wall of other cylindrical workpieces.

[0017] Please also read Figure 2 and Figure 3 The base 10 includes a base body 11 , a positioning ring 12 disposed on the base body 11 , and a screw 13 disposed inside the positioning ring 12 .

[0018] The base body 11 is an inverted U-shaped block as a whole, and a heating module can be placed in the empty part thereof, so as to heat the bushing 30 placed on the base 10, so that the resin changes from a solid state to a viscous flow state, thereby increasing the viscosity of the resin.

[0019] The circumferential inner wall of the positioning ring 12 matches the circumferential outer wall of the bushing 30 , so that after the bushing 30 is placed in the positioning ring 12 , the bushing 30 can be positioned, thereby stabilizing the bushing 30 .

[0020] A screw hole 14 is provided on the circumferential outer wall of the positioning ring 12, and the length direction of the screw hole 14 is perpendicular to the central axis of the positioning ring 12, so that the bushing 30 can be tightened by screwing a flat head screw into the screw hole 14, thereby further stabilizing the bushing 30. The screw hole 14 can also ensure that the bushing 30 will not fall off after the base 10 is placed on its side, thereby preventing the resin from flowing and accumulating on the base 10.

[0021] The screw rod 13 is arranged on the central axis of the positioning ring 12 , and a tool holder truncated platform 15 is arranged at the connection between the screw rod 13 and the positioning ring 12 . The surface of the tool holder truncated platform 15 is smooth so as to reduce the loss when the scraper assembly 20 rotates thereon.

[0022] The screw rod 13 has an external thread on its circumferential outer side wall, so that it can cooperate with the scraper assembly 20, so that the scraper assembly 20 can rise or fall along the length direction of the screw rod 13 when rotating.

[0023] The scraper assembly 20 includes a rotating block 21 , a scraper 22 disposed on one side of the rotating block 21 , and a handle 23 disposed on the rotating block 21 .

[0024] The rotating block 21 is provided with a rotating hole 24, and the rotating hole 24 has an internal thread, and the screw 13 is inserted into the rotating hole 24. In this way, through the cooperation between the internal thread in the rotating hole 24 and the external thread outside the screw 13, the rotating block 21 can move up and down along the length direction of the screw 13 when rotating, thereby ensuring that no material remains on the coating surface.

[0025] Both ends of the scraper 22 protrude from the rotating block 21 . When the rotating block 21 is screwed onto the screw rod 13 and one side of the rotating block 21 abuts against one side of the tool holder circular table 15 , the rotating block 21 is in gap contact with the base body 11 .

[0026] The scraper 22 has a bevel portion 25 on the side away from the rotating block 21. When the scraper assembly 20 is sleeved on the screw 13, the tip of the bevel portion 25 contacts the circumferential inner wall gap of the bushing 30 placed in the positioning ring 12, so that when the scraper assembly 20 is rotated, the viscous resin can be evenly coated on the inner wall of the bushing 30.

[0027] The handle 23 is disposed at the end of the rotating block 21 away from the scraper 22 , so that it is convenient for an operator to rotate the scraper assembly 20 and saves more effort.

[0028] Compared with the prior art, the scraping tool provided by the utility model evenly coats the flowing resin on the inner wall of the village bushing 30 through the rotating scraper 22, and ensures that there is no material residue on the coating surface. The screw hole 14 can ensure that the bushing 30 will not fall after the base 10 is placed on its side, so that the base 10 can be processed on its side to avoid the resin flowing and accumulating on the base 10. The scraper assembly 20 can be made in multiple sets to adapt to the processing of bushings 30 of different specifications, thereby improving the applicability of the tool.

[0029] The above are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Any modification, equivalent substitution or improvement within the spirit of the present invention are included in the scope of the claims of the present invention.
