Problems solved by technology

Ordinary vise adopts threaded clamping mechanism. Although the threaded clamping mechanism is simple in structure and reliable in clamping, its obvious shortcomings are slow clamping action, time-consuming loading and unloading of workpieces, and low work efficiency, especially when workpieces of different sizes are frequently used. Replacement, the number of rotations is more

Embodiment Construction

[0009] Preferred embodiments of the present invention will be further described below in conjunction with accompanying drawings, as figure 1 As shown, a quick eccentric clamp disclosed in the present invention comprises a push-pull rod, an eccentric shaft, a handle, a pressing block, a spring, and a clamp housing. When operating the fixture without clamping, the push-pull rod 1 can be freely pulled. The clamp housing 2 and the bottom plate 7 are connected with hexagon socket bolts. There is a long groove above the fixture housing to limit the rotation of the pressing block 5 . Press block and spring 6 are enclosed within on the push-pull rod. The eccentric shaft 3 is arranged at the upper end of the briquetting block, and the handle 4 can manipulate it to rotate. During operation, push the xuan to tighten the workpiece, and then turn the eccentric shaft hand grip clockwise, the eccentric shaft presses the upper end of the pressing block, and at the same time the pressing...

Abstract

The invention discloses a fast eccentric clamp. The fast eccentric clamp is characterized by comprising a push-pull rod, an eccentric shaft, a handle, a pressing block, a spring and a clamp shell. When the clamp is operated before clamping is achieved, the push-pull rod 1 can be pulled freely. The clamp shell 2 and a base plate 7 are connected through an inner hexagonal bolt. A long slot is formed in the upper portion of the clamp shell for limiting the rotation of the pressing block 5. The push-pull rod is sleeved with the pressing block and the spring 6. The eccentric shaft 3 is arranged at the upper end of the pressing block. The handle 4 can control the eccentric shaft to rotate. The fast eccentric shaft has the advantage that the clamping force of the clamp needs to be proper. If the clamping force is too small, a workpiece is likely to move in the machining process, so that positioning is damaged, the quality is affected, and accidents are likely to occur; if the clamping force is too large, the workpiece and the clamp are deformed, the machining quality is affected, and labor and materials are wasted.

Description

technical field [0001] The invention relates to the technical field of mechanical clamps, in particular to a quick eccentric clamp. Background technique [0002] At present, most of the fixtures used in the production process are ordinary vises. Ordinary vise adopts threaded clamping mechanism. Although the threaded clamping mechanism is simple in structure and reliable in clamping, its obvious shortcomings are slow clamping action, time-consuming loading and unloading of workpieces, and low work efficiency, especially when workpieces of different sizes are frequently used. Replacement, the number of rotations is more. With the needs of the development of machinery manufacturing, new types of fast fixture structures continue to emerge. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a quick eccentric clamp. [0004] The present invention is realized through the following technical solut...
