Description

Technical Field

[0001] The utility model relates to the technical field of electroplating equipment, in particular to a barrel rack for electroplating. Background Art

[0002] Barrel plating is a common electroplating method. During barrel plating, a roller is required. The roller is a material holding device that carries small parts and is plated in the process of continuous rolling. The roller is placed in the electroplating tank to electroplate the parts in the roller. The roller's structure, size, speed, conductive method, and opening rate are all related to the production efficiency and coating quality of barrel plating.

[0003] According to the existing Chinese utility model patent with the announcement number CN212426227U, a drum rack for electroplating is described. The structure is provided with a plurality of baffles extending along the length direction of the inner wall of the electroplating drum, and the horizontal rotation direction of the baffles is 45 degrees. When the electroplating drum rotates, the parts located in the inner and outer sides of the electroplating drum are repeatedly transferred along the inner wall of the electroplating drum between adjacent baffles, and the parts in the electroplating drum can be moved to the outer side to contact the electroplating solution for electroplating, so that the parts in the electroplating drum are electroplated evenly.

DETAILED DESCRIPTION

[0027] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with the embodiments and drawings, and the contents mentioned in the implementation modes are not intended to limit the present invention. The present invention is described in detail below in conjunction with the drawings.

[0028] See also Figure 1-8 The electroplating drum rack specifically implemented includes a gantry 1 and a drum 2. The two ends of the drum 2 are horizontally rotatably arranged at the bottom of the gantry 1. The interior of the drum 2 is a hollow storage cavity 23. The inner wall of the storage cavity 23 is provided with a plurality of baffles 24 extending inwardly and obliquely. The end of the drum 2 is an end cover 3. The end cover 3 at one end of the drum 2 is a fixed end cover 31, and the end cover 3 at the other end of the drum 2 is a driving end cover 32. The interior of the gantry 1 is provided with a gear drive assembly. The drum 2 is driven by the gear The driving assembly is connected to the driving end cover 32 in transmission. The driving end cover 32 is composed of a driving outer ring 321 and a connecting inner disk 322. The driving outer ring 321 is an annular hollow structure. The driving outer ring 321 is rotatably sleeved on the outer side of the connecting inner disk 322. The connecting inner disk 322 is fixedly connected to the end of the drum 2. A ratchet structure 323 is provided between the driving outer ring 321 and the connecting inner disk 322. The driving outer ring 321 rotates unidirectionally along the connecting inner disk 322 as the center through the ratchet structure 323.

[0029] The driving end cover 32 located at one end of the drum 2 adopts an outer ring sleeve structure, and a unidirectionally rotatable ratchet structure 323 is provided between the driving outer ring 321 and the connecting inner disk 322; when the rotation direction of the driving outer ring 321 is the same as the opening direction of the baffle 24, the driving outer ring 321 can drive the connecting inner disk 322 to rotate synchronously through the ratchet structure 323, which effectively achieves the situation that when the rotation direction of the driving outer ring 321 is opposite to the opening direction of the baffle 24, the drum 2 can remain stationary, so that the components inside the drum 2 can be evenly distributed inside the baffle 24 through the baffle 24, preventing the components from gathering.

[0030] Specifically, Figure 7As shown, the ratchet structure 323 is composed of a ball 3231 and an elastic member. The inner ring of the driving outer ring 321 is provided with a plurality of ratchet grooves 3212, and the plurality of ratchet grooves 3212 are distributed in a circumferential array structure. The periphery of the connected inner disk 322 is provided with a plurality of embedded grooves 3221. The ball 3231 is arranged between the ratchet groove 3212 and the embedded groove 3221 through an elastic member. When the driving outer ring 321 is rotated unidirectionally, the ball 3231 is squeezed into the inner part of the embedded groove 3221 by the squeezing of the ratchet groove 3212. When the driving outer ring 321 and the connected inner disk 322 are rotated synchronously, the ball 3231 is squeezed into the ratchet groove 3212 by the squeezing of the elastic member. The ratchet groove 3212 is in the shape of a "water drop", and several ratchet grooves 3212 are distributed along the tangent of the inner disk 322. When the outer ring 321 is driven to rotate in one direction, the ball 3231 is squeezed toward the inside of the inner groove 3221 along one end of the tangent direction of the ratchet groove 3212. When the outer ring 321 is driven to rotate synchronously with the connected inner disk 322, the ball 3231 is buckled in the other end of the ratchet groove 3212. The elastic member is composed of a return spring 3231, one end of the return spring 3231 is fixedly connected to the bottom end of the inner groove 3221, and one end of the return spring 3231 is fixedly connected to the ball 3231.

[0031] When the driving outer ring 321 and the connecting inner disk 322 rotate synchronously, the ball 3231 extends to the inside of the ratchet groove 3212 through the return spring 3231 and is embedded in the ratchet groove 3212, so that the connecting inner disk 322 and the driving outer ring 321 are fixed and limited by the ball 3231, so as to achieve the effect of synchronous rotation;

[0032] When the driving outer ring 321 rotates unidirectionally, the driving outer ring 321 rotates in the tangential direction of the ratchet groove 3212, and the ball 3231 can be squeezed into the inner groove 3221 by the ratchet groove 3212. The connecting inner disk 322 and the driving outer ring 321 are in a state of being connected without an intermediate device, so that the external power cannot be transmitted to the connecting inner disk 322 through the driving outer ring 321, which effectively ensures that the drum 2 can remain stationary when the rotation direction of the driving outer ring 321 is opposite to the opening direction of the baffle 24.

[0033] The structure of the specific gear drive assembly, such as Figure 2As shown, it includes a driving shaft 11 and a driving gear 12, the driving gear 12 is fixedly connected to the end of the driving shaft 11, the driving shaft 11 is horizontally and rotatably connected to the top of the gantry 1, the periphery of the driving outer ring 321 is provided with a tooth groove portion 3211 matching the driving gear 12, the driving outer ring 321 is meshed with the driving gear 12 through the tooth groove portion 3211 for transmission, the bottom end of the gantry 1 is provided with an inwardly protruding rotating shaft 13, the center of the fixed end cover 31 and the center of the connecting inner disk 322 are both provided with mounting holes 3222, and the drum 2 is rotatably set at the center of the rotating shaft 13 through the mounting hole 3222.

[0034] Specifically, the side wall of the drum 2 is a screen portion 21 with a plurality of hole structures, and a conductive structure is formed between the screen portion 21 and the storage cavity 23. The drum 2 is a polygonal columnar structure, and one end face of the screen portion 21 is a detachable opening and closing cover body 22. The opening and closing cover body 22 and the screen portions 21 adjacent to both sides are provided with a snap-fit ​​assembly 4. By removing the opening and closing cover body 22, the parts to be electroplated are placed into the drum 2. When the drum 2 sinks into the electroplating liquid, the electroplating liquid penetrates into the storage cavity 23 through the screen portion 21 on the side wall of the drum 2, so that the electroplating liquid can immerse the parts inside the storage cavity 23.

[0035] The preferred structure of the fastening assembly 4 is as follows: Figure 3 and Figure 8 As shown, it is composed of a plurality of snap-fit ​​plates 41, the middle portion of the snap-fit ​​plate 41 is rotatably disposed on the top end surface of the opening and closing cover body 22, the end portion of the snap-fit ​​plate 41 is a snap-fit ​​protrusion 411, and the screen portion 21 adjacent to the opening and closing cover body 22 is provided with a snap-fit ​​groove 221 matching the snap-fit ​​protrusion 411, and the snap-fit ​​protrusion 411 can be snap-fitted and fixed with the snap-fit ​​groove 221.
