Description

Technical Field

[0001] This utility model relates to the field of lock parts processing technology, specifically to a fixing mechanism for electroplating lock parts. Background Technology

[0002] Electroplating is a process that uses the principle of electrolysis to deposit a layer of metal onto a conductor. Electroplating refers to a surface processing method in which the substrate metal is used as the cathode in a salt solution containing the metal to be plated. Through electrolysis, the cations of the metal to be plated in the plating solution are deposited on the surface of the substrate metal to form a coating.

[0003] The Chinese utility model patent with authorization announcement number "CN213013132U" is specifically "a clamping and fixing structure for lock accessories in electroplating processing". It can effectively clamp and fix lock accessories of different shapes by adjusting the height of the clamping mechanism and the distance between the clamping mechanisms.

[0004] However, during the electroplating process, although the parts of the lock components that come into contact with the clamping mechanism are not submerged in the electroplating tank, they are covered and obstructed, preventing the clamped parts of the lock components from being effectively electroplated. This results in electroplating dead zones and uneven electroplating effects. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a fixing mechanism for electroplating of lock accessories, which can effectively solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

The upper extrusion assembly includes an upper fixed plate that is slidably mounted on one side of the L-shaped base. An extrusion plate is elastically mounted below the upper fixed plate. Several upper rotating rollers corresponding to the lower rotating rollers are rotatably mounted on the lower bottom of the extrusion plate. An extrusion seat extending through to the lower bottom of the upper fixed plate is mounted on the lower bottom of the extrusion plate. The pushing assembly includes a pushing plate that is telescopically slidably mounted on the inner side wall of the L-shaped base and can be completely inserted into the groove.

[0008] Furthermore, two rows of equally spaced lower fixed seats are installed on the inner bottom of the L-shaped base, and the two ends of the rotating roller are rotatably installed with the corresponding lower fixed seats.

[0009] Further, the top end of the L-shaped base is vertically fixedly installed with a top plate, and the lifting cylinder is fixedly installed on the top of the top plate, and a lifting rod is installed between the output end of the lifting cylinder and the upper fixed plate.

[0010] Further, the lower bottom of the extrusion plate is installed with two rows of upper fixed seats which are distributed at equal intervals, the upper rotating rollers are rotatably installed at the two ends of the upper fixed seats respectively, and the upper fixed plate and the extrusion plate are installed with four springs.

[0011] Further, the pushing assembly further comprises a telescopic cylinder which is fixedly installed at the top end of the top plate, and a connecting bent rod is installed at the output end of the telescopic cylinder and fixedly connected with the pushing plate through the L-shaped base.

[0012] Compared with the prior art, the technical scheme has the following beneficial effects:

[0013] 1. The L-shaped base is arranged to place the lock accessory to be electroplated, the lower rotating roller which can rotate is arranged at the lower bottom of the inner side of the L-shaped base, the upper rotating roller which can be lifted and slid and rotated is arranged above the lower rotating roller, the lock accessory is extruded and fixed between the upper and lower rotating rollers, the contact position of the lock accessory and the upper and lower rotating rollers is quickly adjusted through the pushing of the pushing plate, so that the originally covered part of the lock accessory is exposed in the electroplating tank again, the electroplating dead angle is avoided, and the uniformity of the electroplating effect is improved.

[0014] 2. When the upper rotating roller is lowered to the contact position with the upper surface of the lock accessory, the extrusion seat between the adjacent two upper rotating rollers is continuously lowered in height until it is extruded and contacted on the upper surface of the lock accessory, so that the stability of the lock accessory clamped by the upper and lower rotating rollers is improved.
