Abstract

The invention discloses a double-cylindrical cam clamp with a locking mechanism, which belongs to the technical field of clamps for mechanical processing, and includes a frame on which a rack and a transmission device are arranged horizontally, an output end of the transmission device and one end of the rack The other end of the rack is meshed with two symmetrically arranged gears respectively. The gear is set on the lower end of the gear shaft and fixed with the gear shaft through the positioning key. One end of the gear shaft is vertically erected on the frame through the bearing, and the other end of the gear shaft is passed through The guide key is matched with the cylindrical cam in clearance, and the end of the cylindrical cam facing away from the gear shaft is sequentially fitted with the pressure plate and the limit structure; the spiral groove on the cylindrical cam is fitted with a guide post, and the end of the guide post facing away from the cylindrical cam is connected with the vertical bracket One is fixed, one end of the support one is fixed with the frame, the other end of the support one is provided with a guide groove, and one end of the pressing plate is arranged in the guide groove. The invention has a simple and compact structure, can realize mechanical and hydraulic double self-locking, and keeps the workpiece in a clamped state with sufficient surface contact.

Description

technical field

[0001] The invention belongs to the technical field of clamps for mechanical processing, and in particular relates to a double cylindrical cam clamp with a locking mechanism. Background technique

[0002] At present, the clamping mechanism on the market either has no self-locking function, or when the workpiece has a machining error, the clamped surface of the workpiece cannot fully contact the pressing block, or the clamping plate cannot do linear motion, and the clamping angle is different for different workpieces. Uneven clamping force. In view of the above reasons, the market is in urgent need of a fixture with self-locking, constant clamping angle when the workpiece size changes, and a clamping surface that can fully contact the workpiece. Contents of the invention

[0003] In view of this, the present invention provides a double cylinder cam clamp with a locking mechanism to solve the deficiencies in the prior art.
