Description

Technical Field

[0001] This utility model relates to the technical field of mechanical parts processing, and in particular to a multi-station rapid clamping device. Background Technology

[0002] Currently, for example, some aerospace bolts and pins require irregular shapes to be machined on the end face to achieve certain functions. Due to the special materials and forming processes of these products, the precision requirements of the irregular structures are quite high, making them unsuitable for processing using traditional hot heading, cold heading, and extrusion methods. Similarly, some medical device components require multiple clamping, milling, drilling, and tapping operations. These components are small in size and have high precision requirements, necessitating frequent clamping and alignment during machining.

[0003] Because the above-mentioned parts require high machining accuracy, they can usually only be machined by clamping them individually and aligning their centers.

[0004] Regarding the aforementioned technologies, the applicant found that the two products have low clamping efficiency, require frequent replacements leading to low processing efficiency, have high skill requirements, and severely restrict production capacity during batch processing.

It uses a groove structure for positioning, and can achieve precise positioning and processing of multiple parts in one clamping. It can achieve rapid clamping and loosening by using a cam mechanism, and adopts a floating pressure plate mechanism to achieve simultaneous clamping and loosening at multiple points.

[0007] A multi-station rapid clamping device includes a base plate with a positioning block on the base plate. Floating pressure plate mechanisms are provided on both sides of the positioning block. The floating pressure plate mechanisms cooperate with the positioning block to form multiple groove structures. Components are placed in the groove structures. A cam mechanism is provided on one side of the floating pressure plate mechanism, and the cam structure connects two floating pressure plate mechanisms.

[0008] Furthermore, the cam mechanism includes a cam block, a connecting screw, and an actuating screw. The connecting screw and the actuating screw are connected through the cam block. The connecting screw passes through the positioning block and is connected to two floating pressure plate mechanisms respectively. The connecting screw is hinged to the cam block. A limiting block is provided at the end of the connecting screw away from the cam block. The limiting block is set to abut against the adjacent floating pressure plate mechanism. The cam block is set to abut against the adjacent floating pressure plate mechanism. The actuating screw is fixedly connected to the cam block.

[0009] Furthermore, the floating pressure plate mechanism includes a floating pressure plate and several pressure blocks. The pressure blocks cooperate with the positioning blocks to form a groove structure. The floating pressure plate is in contact with the adjacent limiting block and cam block.

[0010] Furthermore, a compression spring is fitted onto the connecting screw, and the compression spring is positioned between the floating pressure plate and the positioning block.

[0011] Furthermore, a washer is provided between the floating pressure plate and the cam block.
