Description
Technical Field
The utility model relates to the technical field of machining, in particular to a machine tool clamp for clamping a continuously variable-diameter part.
Background
The jig is a device for fixing a processing object to occupy a correct position for receiving construction or inspection in a machine manufacturing process. The universal fixture for the machine tool can be used for positioning and clamping parts with regular and square shapes, but in the field of machining, workpieces with continuous variable diameters are often required to be machined, and the universal fixture for the machine tool cannot be used for clamping and subsequent cutting machining cannot be carried out.
SUMMERY OF THE UTILITY MODEL
In view of this, the utility model provides a machine tool fixture for clamping a continuously variable-diameter part. The machine tool fixture can be used for conveniently, quickly and safely clamping variable-diameter workpieces, and the size precision and the surface roughness of subsequent parts are ensured.
In order to achieve the purpose, the technical scheme adopted by the utility model is as follows:
a machine tool clamp for clamping a continuously variable-diameter part comprises a base frame 1 and a locking screw 5; the base frame is of a square frame structure, one of the opposite sides of the base frame is provided with a pressing block, and any one of the other opposite sides of the base frame is provided with a positioning block;
the positioning block and the pressing block are both provided with long slotted holes, the base frame is provided with threaded holes corresponding to the long slotted holes, the positioning block and the pressing block are connected with the base frame through locking screws 5 penetrating through the long slotted holes and the threaded holes, and both the positioning block and the pressing block can move along the extension direction of the long slotted holes;
a cushion block 2 is also arranged between the pressing block and the base frame; the inner side surface of the positioning block and the inner side surface of the pressing block for contacting parts are both arc-shaped surfaces.
Furthermore, each pressing block is provided with at least two parallel long slotted holes.
The utility model adopts the technical scheme to produce the beneficial effects that:
1. according to the utility model, the positioning blocks which are opposite to each other clamp the variable-diameter part through the movement of the screw in the long slot hole, so that the variable-diameter part can be fixed in the base frame and can also be fixed through the positioning blocks; convenient and fast, and ensures the sequential processing of subsequent parts.
2. The positioning block is provided with an arc surface, and the arc surface is in line contact with the variable-diameter part, so that fixation can be realized through clamping in multiple directions, and the damage to the surface of the variable-diameter part is reduced.
3. The utility model has simple structure, convenient manufacture and convenient production and application.
