Description

Support of many sizes of adaptation charging basket presss from both sides integral type clamping jaw

Technical Field

The utility model relates to a centre gripping technical field, concretely relates to support of many sizes charging basket of adaptation presss from both sides integral type clamping jaw.

Background

With the rapid development of industrial technology, in order to avoid the harm of severe working environment to the health of workers and solve the problem of low manual operation efficiency, the manual operation is replaced by robots more and more. Especially in the field of automation and intelligent manufacturing at present, it is the most common solution to adopt a robot to carry on a clamping jaw mechanism to clamp a material carrier for carrying and transferring. The existing clamping jaw designed for carrying a charging basket is used for clamping the edge of the charging basket by positioning and installing an electric or pneumatic driven clamping type clamping jaw mechanism at the tail end of a mechanical arm; or a specially-made fork structure for the charging basket is arranged at the tail end of the mechanical arm so as to support the edge of the fork and realize the grabbing function of the charging basket. And then the material basket is conveyed and transferred by driving the mechanical arm.

Fig. 1 shows two common jaw mechanisms of the prior art. Fig. 1(a) is a typical clamping type clamping jaw structure diagram, the whole mechanism is fixedly mounted with the tail end of a mechanical arm through a connecting piece, clamping jaw tools are respectively mounted on a left rotor and a right rotor of a clamping jaw electric cylinder, and a driving signal is sent to the clamping jaw electric cylinder to drive the two clamping jaw tools to open and close. Fig. 1(b) shows a typical fork type clamping jaw, two forks are fixedly mounted with the tail end of the mechanical arm through connecting pieces, and the mounting distance of the two forks is designed according to the matching of the size of the edge of a charging basket. When the charging basket is clamped, the mechanical arm drives the fork type clamping jaw to reach a parallel surface slightly lower than the plane of the upper edge of the charging basket, the opening of the fork faces the charging basket, the fork is parallel to the long edge direction of the charging basket edge, then the mechanical arm drives the fork to move forwards, the fork is inserted into the bottom of the edge of the charging basket, and then the mechanical arm is driven to vertically lift upwards, so that the fork supports the charging basket.

The burden of the weight of the clamping jaw structure can also reduce the effective load of the mechanical arm, limit the weight of materials borne in the charging basket and cause invariance in the production process. On the other hand, the clamping form of the existing clamping jaw on the charging basket leads to that the clamping jaw can only be suitable for the charging basket with one size, and the universal adaptation to the charging baskets with various sizes cannot be realized. When the size of the clamped charging basket is changed, parts of the clamping jaw need to be replaced or the installation position needs to be adjusted, so that the assembly and adjustment workload is increased, the working efficiency is reduced, and the flexible design of production equipment or a system where the mechanical arm and the clamping jaw are located is limited.
