Description

Bench vice for assembly

Technical Field

The utility model belongs to the technical field of the bench vice for the assembly.

Background

At present, a commonly known bench vice is a universal fixture for clamping a workpiece, and the structure of the bench vice comprises a vice body, a base, a guide nut, a lead screw, a vice jaw body and the like. However, when the shaft-type part is assembled by the bench vice, the shaft-hub part is not fixed in the radial direction, so that the shaft-hub part is easy to deflect, the assembly efficiency is low, and the surface of the part can be damaged.

There is therefore a need for a vise that can better accommodate radially varying parts at the same time.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the defects of the prior art and providing a bench vice for assembly with better stability and adaptation surface.

In order to achieve the purpose, the utility model adopts the following technical proposal:

the utility model provides an assembly is with bench vice, includes base, the slider of keeping silent, screw rod, locating piece and three-jaw chuck, the locating piece locate the back of the slider of keeping silent, three-jaw chuck locate the back seat of base inboard, the locating piece on be equipped with conical recess, its circular cone axis with the central axis of three-jaw chuck be same water flat line.

Furthermore, the positioning block is movably connected with the jaw sliding block and is fixed through a bolt; the three-jaw chuck is movably connected with the backseat and is fixed through a bolt.

The bench vice for assembly further comprises a groove blocking block, a screw rod and a handle, wherein the groove blocking block is positioned below the jaw sliding block and arranged in a sliding groove of the base, the front end of the screw rod is in matched contact connection with a screw hole in the jaw sliding block, and the handle is inserted into a tail end through hole of the screw rod; when the handle is rotated, the screw rod drives the jaw sliding block to move on the base. Furthermore, the handle and the screw rod are subjected to anti-falling treatment, and the adopted method is to extrude the two ends of the handle to be flat or add a rubber sleeve.

The utility model has the advantages that:

the utility model provides a bench vice is used in assembly, when carrying out axle type part assembly, with three-jaw chuck centre gripping axle type part, the slider position of keeping silent is adjusted to the twist grip, supports parts such as bearing or axle sleeve between axle and locating block, can assemble the tip to axle type part with parts such as bearing or axle sleeve. After the three-jaw chuck and the positioning block are disassembled and replaced by other required clamping pieces, all functions of the traditional bench vice can be possessed.

Therefore, compare the function of using traditional bench vice, the utility model discloses can also be used for assembling the shaft hub class part that traditional bench vice is difficult to the centre gripping, it is crooked more difficult to the unstability in addition in assembling process, also be difficult to cause the damage to the part surface, multiplicable assembly efficiency and precision. Furthermore, the utility model discloses all parts related in the structure all easily process, low in production cost.

For better understanding of the present invention, the following drawings are provided to explain the present invention together with the embodiments of the present invention, and do not constitute limitations of the present invention.

Detailed Description

As shown in fig. 1-5, the utility model provides a bench vice for assembly, including base 1, jaw slider 2, groove 3, screw rod 4 and handle 5, locating piece 6 and three-jaw chuck 7, locating piece 6 locate the back of jaw slider 2, three-jaw chuck 7 locate the back seat inboard of base 1, locating piece 6 on be equipped with conical recess, its conical axis with the central axis of three-jaw chuck 7 be the same horizontal line;

the positioning block 6 is movably connected with the jaw sliding block 2 and is fixed through a bolt; the three-jaw chuck 7 is movably connected with the backseat and is fixed through bolts.

The blocking groove block 3 is positioned below the jaw sliding block 2 and is arranged in a sliding groove of the base 1, the front end of the screw rod 4 is in matched contact connection with a screw hole in the jaw sliding block 2, and the handle 5 is inserted into a tail end through hole of the screw rod 4; when the handle 5 is rotated, the screw rod 4 drives the jaw sliding block 2 to move on the base.

In a preferred embodiment, the anti-falling treatment is performed between the handle 5 and the screw rod 4 by extruding two ends of the handle 5 into flat heads or adding rubber sleeves.

When the shaft parts are assembled, the shaft parts are clamped by the three-jaw chuck, the position of the jaw sliding block is adjusted by rotating the handle, and the parts such as the bearing or the shaft sleeve are abutted between the shaft and the positioning block. Because the positioning block is provided with the concave conical concave pit, the axis of the concave conical concave pit is collinear with the axis of the three-jaw chuck, and radial constraint can be performed on parts such as a bearing or a shaft sleeve. Then the handle is rotated, and the parts such as the bearing or the shaft sleeve can be assembled at the end part of the shaft part. In addition, when the bench vice needs to be used as a common bench vice to work, the bolt connection between the three-jaw chuck and the bench vice body and the bolt connection between the positioning block and the bench vice sliding block need to be disassembled, and the two are replaced by the required clamping pieces, so that all functions of the conventional bench vice can be achieved.
