Description

Technical Field

[0001] The invention particularly relates to a processing device for toothed elastic cylindrical pins. Background Art

[0002] In the machinery industry, there are many ways to connect and fasten parts, such as common threaded connections, rivet connections, pin connections, key and spline connections, etc. According to their functions, pins can be divided into positioning pins, connecting pins, safety pins and cylindrical pins, etc., and cylindrical pins can be divided into ordinary cylindrical pins and toothed elastic cylindrical pins. Elastic cylindrical pins are different from ordinary cylindrical pins and are used in occasions with impact and vibration. They are headless hollow cylinders used for positioning, connecting and fixing parts, and have good elasticity and shear resistance.

[0003] In the related art, due to the wide application of elastic cylindrical pins, they need to be produced in large quantities. During production, processing equipment for toothed elastic cylindrical pins needs to be used to process them. However, the current processing equipment still has certain problems. For example, when processing cylindrical pins, a fixing fixture needs to be used to clamp and lock the elastic cylindrical pins to prevent the elastic cylindrical pins from moving during the processing. However, in order to meet processing requirements, such as grinding and polishing, the outer wall of the cylindrical pin needs to be processed as a whole. Therefore, during processing, the cylindrical pin needs to be continuously disassembled and rotated so that different positions of its outer wall are in contact with the grinding and polishing equipment. This results in a large amount of human resources being required to operate during processing. The operation is cumbersome and also seriously affects work efficiency. For this reason, we propose a processing equipment for toothed elastic cylindrical pins to solve this problem. Summary of the invention

[0037] It should be noted that, when processing the cylindrical pin, a fixing fixture is needed to clamp and lock the elastic cylindrical pin to prevent the elastic cylindrical pin from moving during the processing.

Therefore, during processing, the cylindrical pin needs to be constantly disassembled and rotated so that different positions of its outer wall are in contact with the grinding and polishing equipment. This results in a large amount of human resources being consumed to operate during processing. The operation is cumbersome and also seriously affects the work efficiency.

[0039] By utilizing the setting of the rotating mechanism 4, the driven disk 41 can be synchronously linked with the active disk 46 through the belt 47, thereby driving the first support rod 42, the second support rod 43 and the tray 44 to rotate as a whole, and driving the elastic cylindrical pin to rotate as a whole, so that the circumferential wall of the cylindrical pin can be evenly processed, avoiding the need to manually adjust the angle of the cylindrical pin. It is simple and practical, and greatly improves the processing efficiency.

[0040] In this embodiment, the height adjustment mechanism 7 also includes a driven bevel gear 74, a driving bevel gear 75 and a rocker arm 76. The driven bevel gear 74 is coaxially fixed to the bottom end of the screw rod 73, and the rocker arm 76 is rotatably connected to the supporting seat 3.

[0041] In this embodiment, one end of the clamping plate 64 away from the adjusting rod 65 is rotatably connected to an abutment plate 66 , and the abutment plate 66 abuts against the elastic cylindrical pin, thereby quickly locking the cylindrical pin.

[0042] In this embodiment, a limiting rod 67 is fixed on the outer wall of the guide rod 62, and a slot is provided on the linkage seat 63. The limiting rod 67 is slidably engaged in the slot of the linkage seat 63, and the linkage seat 63 is limited by the limiting rod 67 to prevent it from slipping.

[0043] In this embodiment, a return spring 68 is sleeved on the guide rod 62 , one end of the return spring 68 abuts against the tray 44 , and the other end abuts against the linkage seat 63 , so that the return spring 68 can quickly return to the linkage seat 63 .

[0044] In this embodiment, the notch on the top of the limiting bracket 71 and the adjusting rod 72 are both polygonal structures, and the polygonal structure is used to limit the adjusting rod 72 to prevent the adjusting rod 72 from rotating when the thread linkage is used.

[0045] In this embodiment, arc-shaped notches are provided on the outer walls of the driven disk 41 and the driving disk 46, and the belt 47 is clamped in the arc-shaped notches. The arc-shaped notches are used to limit the belt 47 to prevent the belt 47 from slipping.

[0046] In this embodiment, the diameter of the driven disk 41 is larger than that of the driving disk 46, and the inner wall of the belt 47 and the arc-shaped grooves on the outer walls of the driven disk 41 and the driving disk 46 are all frosted surfaces. The frosted surface is used to increase friction and prevent the belt 47 from slipping during transmission.

[0047] The working principle and use process of the present invention are as follows: when in use, the elastic cylindrical pin to be processed is first placed between the tray 44 and the docking tray 5, and then the active bevel gear 75 is driven to rotate by the rocker arm 76, thereby driving the driven bevel gear 74 to mesh and link, and the driven bevel gear 74 drives the screw rod 73 to rotate and causes the adjusting rod 72 to thread and link, thereby driving the tray 44 and the clamping and locking mechanism 6 thereon to move upward as a whole until the two ends of the cylindrical pin abut against the linkage seats 63 in the upper and lower groups of clamping and locking mechanisms 6. When abutting, the linkage seat 63 drives the adjusting rod 65 and the clamping plate 64 to link, and then the elastic cylindrical pin is quickly clamped and locked through the clamping plate 64, and then the active disk 46 is driven to rotate by the servo motor 45, and the driven disk 41 is synchronously linked with the active disk 46 through the belt 47, thereby driving the first support rod 42, the second support rod 43 and the tray 44 to rotate as a whole, and driving the elastic cylindrical pin to rotate as a whole, so that the peripheral wall of the cylindrical pin can be evenly processed.

[0048] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
