[0001] The utility model relates to the technical field of automobile parts processing, and more precisely to a parts knurling and flattening device. Background Art

[0002] Knurling is a mechanical process that creates a pattern on the handle or other working surface of a metal product. Knurling for automotive parts is a metalworking technique primarily used in the automotive industry. This technique creates grooves or patterns on the surface of sheet metal, increasing surface roughness to provide anti-slip properties and enhance grip. In areas where increased grip is required, such as pedals and parking brakes, knurling provides a better grip, enabling drivers to operate quickly and accurately in emergency situations.

[0003] Generally, automobile parts are knurled by two rollers with textured outer surfaces, through which automobile parts are rolled and knurled. The knurling formed on the outer surface of automobile parts will have burrs, which need to be flattened and polished. The existing knurling and knurling flattening and polishing devices are set separately, which makes the knurling production efficiency of automobile parts low. Therefore, a part knurling flattening device that can flatten and polish automobile parts after knurling is needed.

[0004] In view of this, the utility model provides a part knurling flattening device. Utility Model Content

[0005] The purpose of the utility model is to provide a part knurling flattening device in view of the defects of the prior art, so as to solve the problems raised by the above background technology.

[0009] As a further improvement of the technical solution, a driving motor 2 is installed on the first moving block penetrating the roller, and a moving block 2 which rises and falls together with the moving block is rotatably installed on the other end of the roller.

[0010] As a further improvement of the present technical solution, the fixing frame is fixedly mounted on the side wall of the supporting frame, and the rotating roller flattens and grinds the knurled parts flowing out from between the upper knurled roller and the lower knurled roller through a frosted sleeve sleeved on the outer surface.

[0022] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more precise definition of the protection scope of the present invention.

[0023] like Figure 1-5 As shown, the device includes a mounting frame 1, and a plurality of rollers 2 for conveying parts are rotatably installed inside the mounting frame 1. The rollers 2 are rotated by being connected to the belt on the driving motor 304. A knurling assembly 3 for knurling the outer surface of the part is installed on the top of the mounting frame 1, and a roller 4 is installed on the outer side of the knurling assembly 3. A frosted sleeve 5 for flattening and polishing the knurled edges of the part is installed on the outer surface of the roller 4. Adjustment components 6 for lifting up and down are installed at both axial ends of the roller 4, and a placement component 7 for elastically placing the part is provided at the bottom of the frosted sleeve 5.

[0024] The parts are transported to the knurling assembly 3 for knurling by rotating multiple rollers 2 on the mounting frame 1. The knurled parts are transported between the rotating roller 4 and the placement assembly 7. The knurled parts will bend. The placement assembly 7 supports the bent parts through the buffer spring 703, so that the rotating roller 4 can stably flatten and grind the knurled burrs on the bent parts through the frosted sleeve 5 sleeved on the outer surface.

[0025] First, the specific structure of the knurling assembly 3 is disclosed. The knurling assembly 3 includes a support frame 301 fixedly mounted on the top of the mounting frame 1. The upper knurling roller 302 and the lower knurling roller 303 for knurling the surface of the part are rotatably mounted on the inner wall of the support frame 301. The outer wall of the support frame 301 is mounted with a driving motor 304. The output shaft of the driving motor 304 passes through the support frame 301 and is mounted inside the lower knurling roller 303. The other ends of the upper knurling roller 302 and the lower knurling roller 303 pass through the support frame 301 and are connected by gear meshing.

[0026] By energizing the driving motor 304, the lower knurled roller 303 is driven to rotate, so that the gear at the other end of the lower knurled roller 303 drives the upper knurled roller 302 to rotate, and the parts conveyed between the upper knurled roller 302 and the lower knurled roller 303 through the roller 2 are knurled, thereby achieving the effect of knurling the parts.

[0027] According to the above disclosure of the specific structure of the adjustment component 6, the adjustment component 6 includes a fixed frame 601, an inner wall of the fixed frame 601 is provided with a through hole 602, a telescopic cylinder 603 is installed on the top of the fixed frame 601, and a moving block 1 604 is installed inside the through hole 602. The telescopic rod of the telescopic cylinder 603 passes through the fixed frame 601 and is fixedly installed on the top of the moving block 1 604. The two sides of the moving block 1 604 are slidably installed in the slide grooves 605 opened on both sides of the inner wall of the through hole 602. One end of the roller 4 passes through the moving block 1 604 and is provided with a drive motor 2 8. The other end of the roller 4 is rotatably provided with a moving block 2 9 which rises and falls with the moving block 1 604. The fixed frame 601 is fixedly installed on the side wall of the support frame 301. The roller 4 flattens and grinds the knurled parts flowing out between the upper knurled roller 302 and the lower knurled roller 303 through the frosted sleeve 5 sleeved on the outer surface.

[0028] When flattening and polishing the knurled parts, the thickness of the parts is different, and the telescopic cylinder 603 installed on the top of the fixed frame 601 is telescopic, and the moving block 1 604 connected to the telescopic rod of the telescopic cylinder 603 is lifted up and down, so that the roller 4 installed between the moving block 1 604 and the moving block 2 9 is adjusted up and down, and the roller 4 is driven by the driving motor 2 8 to rotate. The roller 4 rotates rapidly, so that the frosted sleeve 5 connected to the outer surface of the roller 4 flattens and polishes the knurled burrs on the knurled parts. The frosted sleeve 5 is a frosted paper, and different specifications can be replaced to polish objects.

[0029] As described above, the specific structure of placement assembly 7 is disclosed. It includes a fixed plate 701 with a notch 702 defined at its top. Multiple buffer springs 703 are mounted on the bottom of the inner wall of notch 702. A slideway 705 is defined within the inner wall of notch 702. An adjustment plate 704 is mounted within slideway 705 to support the placement of knurled parts. The adjustment plate 704 is mounted on top of the buffer springs 703, which provide support for the downward movement of the adjustment plate 704 after the parts are placed.

[0030] After the knurling assembly 3 knurls the part, the part is transported from the knurling assembly 3 to the middle of the adjusting plate 704 and the rotating roller 4. The rotating roller 4 rotates rapidly to flatten and grind the knurled burrs on the outer surface of the part. However, the part will bend after knurling. The bent part is subjected to different grinding forces between the adjusting plate 704 and the rotating roller 4. The flattening and grinding force of the roller 4 is large at the upward bending part of the part, which will completely flatten and disappear the knurling. The force is small at the downward bending part, and the burrs are flattened and polished unevenly. The position of the adjusting plate 704 can be adjusted up and down by the buffer spring 703. When the part bent upward is polished in the rotating roller 4, the adjusting plate 704 is squeezed and lowered. When the part bent downward is polished in the rotating roller 4, the adjusting plate 704 is reset by the buffer spring 703, so that the roller 4 has a moderate force on flattening and grinding the knurled burrs of the part, thereby achieving the effect of stably flattening and polishing the knurled burrs by adjusting the position of the bent part.

[0031] In summary, the working principle of this solution is as follows:

[0032] The lower knurled roller 303 is driven to rotate by energizing the driving motor 304, so that the gear at the other end of the lower knurled roller 303 drives the upper knurled roller 302 to rotate, and knurls the parts conveyed through the roller 2 between the upper knurled roller 302 and the lower knurled roller 303. After the knurling assembly 3 knurls the parts, the parts are conveyed from the knurling assembly 3 to the middle of the adjusting plate 704 and the rotating roller 4. The rotating roller 4 rotates rapidly, which can flatten and grind the knurled burrs on the outer surface of the parts. The position of the adjusting plate 704 can be adjusted up and down by the buffer spring 703. When the bent upward part is polished in the rotating roller 4, the adjusting plate 704 is squeezed and lowered. When the bent downward part is polished in the rotating roller 4, the adjusting plate 704 is reset by the buffer spring 703, so that the rotating roller 4 has a moderate force to flatten and grind the knurled burrs of the parts, thereby achieving the effect of stably flattening and grinding the knurled burrs by adjusting the position of the bent part.
