A labor-saving linkage positioning and locking structure

Abstract

The invention discloses a labor-saving linkage positioning and locking structure, which belongs to the technical field of mechanical processing equipment positioning and includes connecting rods, claws, screw rods, racks, cross universal joints, guide rails, locking mechanisms, spring support seats, positioning Groove and leaf spring; the guide rail is horizontally installed on the frame, and the guide rail is provided with a positioning groove; the side of the frame is provided with a spring support seat, and a leaf spring is arranged on the spring support seat, and the leaf spring is parallel to the guide rail; The connecting rod is horizontally arranged below the guide rail perpendicular to the guide rail, the screw rods are respectively connected to both ends of the connecting rod, and cross universal joints are arranged between the connecting rod and the screw rod; the claws are respectively matched and installed on both ends of the connecting rod. On the screw rods at the end, one of the screw rod ends is fixedly connected with a locking mechanism. The technical solution uses the positioning of the rollers and the linkage of the claws, so that the mechanical load with rollers can be positioned and locked quickly, stably and reliably for a long time on the guide rail, and the starting force is small when restarting, and there is no scratch on the guide rail.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing equipment positioning, and relates to a horizontal guide rail roller positioning and locking device used for the limit position of a vehicle-mounted sliding frame, in particular to a labor-saving linkage positioning and locking structure. Background technique [0002] In mechanical equipment with guide rails, in order to reduce the friction between the sliding mechanism and the guide rail, the sliding friction is often replaced by rolling friction by installing rollers, so as to reduce the power requirements of the moving mechanism on the drive system and reduce the movement The mechanism wears on the guide rail. [0003] However, on the guide rails of the vehicle or other motion platforms, because the starting force of the rollers is small, it is easy to move, and it is difficult to perform positioning and locking. However, the structure using the latch for positioning cannot meet ...

Problems solved by technology

[0003] However, on the guide rails of vehicles or other motion platforms, due to the small starting force of the rollers, it is easy to move, and it is difficult to perform positioning and locking.

However, the structure using pins for positioning cannot meet the locking transportation requirements, and the fast locking structure cannot provide sufficient locking force. The locking mechanism using camshaft structure needs to provide a large operating torque, and the locking stroke is longer. Small
