Description

Bench vice with chuck convenient to replace

Technical Field

The utility model relates to a pincers worker technical field especially relates to a conveniently change bench vice of chuck.

Background

The bench vice is also called vice or bench vice. A vise is a universal fixture used to clamp workpieces. The device is arranged on a workbench and used for clamping and stably processing workpieces, and the structure of the device comprises a clamp body, a base, a guide nut, a lead screw, a clamp mouth body and the like. The movable caliper body is in sliding fit with the guide rail of the fixed caliper body through the guide rail, and the lead screw is arranged on the movable caliper body, can rotate but cannot axially move and is matched with a lead screw nut arranged in the fixed caliper body. When the handle is shaken to rotate the screw rod, the movable vice body can be driven to move axially relative to the fixed vice body, and the clamping or loosening effect is realized.

In order to increase the clamping force, the metal chuck that is equipped with anti-skidding line is usually fixed through the bolt on the pincers body, further press from both sides tight work piece through the metal chuck, the metal chuck is screwed into through forward bolt and is fixed on the pincers body, along with the increase of live time, thereby two metal chucks can constantly extrude with the work piece and make its surface have the wearing and tearing of certain degree, fixing bolt also can be extruded to a certain extent this moment, be difficult to screw the bolt off when needs are changed like this, waste time and energy.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that the bench vice overcomes the defects existing in the prior art and provides a bench vice with a chuck convenient to replace.

The utility model discloses a realize through following technical scheme: the utility model provides a conveniently change bench vice of chuck, includes the base, fixes the fixed vice body on the base, with fixed vice body sliding fit's activity vice body and the lead screw of threaded connection on fixed vice body, fixed vice body and the relative fixed surface of activity vice body have the lug, be equipped with the chuck on fixed vice body and the activity vice body respectively, be equipped with on the chuck with lug matched with slot, the lug is pegged graft in the slot, the both ends of chuck are equipped with the mounting hole respectively, relative thread groove has been seted up respectively at the both ends of chuck and the both ends of lug, is located thread groove and the mounting hole intercommunication on the chuck, thread groove female connection has the fastening bolt who is located the mounting hole.

The utility model has the advantages that: the clamp head is fixed with the clamp body through the fastening bolts on the two sides, so that the clamp head cannot extrude the fastening bolts due to abrasion generated when clamping a workpiece, and the clamp head can be conveniently screwed off in the later period; the fixing effect of the chuck can be improved by the matching of the insert block and the slot, the chuck is supported, the fastening bolt can not protrude through the mounting hole, and the chuck cannot be influenced to clamp a workpiece.
