Description
Technical Field
The utility model belongs to the technical field of machine-building industry and automatic welding field are applicable to IC and equip (semiconductor device, flat panel display's special production facility), and the fixed clamp in the special-shaped parts course of working is tight among the aerospace manufacturing.
Background
At present, the demand of more and more cylinder parts exists in the semiconductor industry, clamping is difficult in the processing process of the special-shaped cylinder parts, and deformation often occurs in the processing process due to the particularity of the special-shaped cylinder parts, so that a special clamping device is needed for fixing the parts.
SUMMERY OF THE UTILITY MODEL
The utility model aims at improving the safety and the efficiency in the workpiece machining process.
In order to realize the purpose, the technical scheme adopted by the utility model is as follows:
a lever clamping device for special-shaped parts comprises a clamping arm, a lever I, a positioning pin, a lever II, a base, a fixing pin, a nut, a fixing shaft, a locker and a low end cover; a columnar cavity is arranged in the base, and a first lever and a second lever which are combined into a whole are arranged in the cavity; the tail ends of the two clamping arms are connected with each other through a fixed shaft on the first lever in a shaft coupling mode, then the fixed shaft is covered by the second lever, and finally the first lever is connected with the second lever through a fixed pin; a sliding roller is arranged on the bottom corner of the clamping arm through a positioning pin; two protruding ends of the positioning pin are fixedly connected into the groove of the base; the tail end of the first lever is provided with a lead screw, the lead screw penetrates through the base and the end cover, and a nut screwed on the lead screw is arranged in the end cover, so that the first lever slides left and right in the base, and the clamping and opening of the clamping arm are realized.
The utility model has the advantages that:
1. the utility model discloses simple structure, the practicality is strong, and is with low costs, and the clamping mode is stable, and the atress is even and stress distribution is comparatively concentrated reliably, can obtain using in accurate spare part course of working.
2. The utility model discloses two tight arms of clamp are linked to the connector, and the effect of locating pin is for pressing from both sides tight or skew slide when lax in tight arm clamp, and the device can be along with the size of the tight arm of clamp of change of the shape of part regulation to realize the device's multifunctionality. The special-shaped parts with different sizes and different shapes can be clamped, and meanwhile, the parts are not easy to move in the machining process.
