Description

Four-jaw chuck jaw suitable for square workpiece

Technical Field

The utility model relates to a machining makes technical field, concretely relates to jack catch for four-jaw chuck suitable for square workpiece.

Background

The chuck is a mechanical device used for clamping a workpiece on a machine tool, and is a machine tool accessory for clamping and positioning the workpiece by utilizing the radial movement of movable clamping jaws uniformly distributed on a chuck body. The workpiece has a round workpiece and also has a square workpiece, and if the clamping jaws for clamping the round workpiece are used for clamping the square workpiece, the workpiece can be deviated due to inaccurate positioning or insufficient clamping force in the clamping process, so that the machining precision and the machining quality of the workpiece are directly influenced.

SUMMERY OF THE UTILITY MODEL

In order to solve the problem, the utility model discloses provide a structural design is reasonable to square workpiece, and the centre gripping is simple and stable firm, can effectively improve the four-jaw chuck jack catch of machining precision and quality.

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

the utility model provides a jack catch for four-jaw chuck suitable for square workpiece, includes the jack catch body, jack catch body bottom is equipped with the location shrinkage pool, jack catch body left side is the centre gripping contact surface, be equipped with trapezoidal slip table of preventing on the centre gripping contact surface, the body top is equipped with first boss, second boss and third boss.

As an optimized technical scheme of the utility model, the centre gripping contact surface is right angle V type structure.

As an optimal technical scheme of the utility model, the location shrinkage pool passes through interference fit with the location relief hole on the chuck groove and fixes on the chuck.

As an optimized technical scheme of the utility model, trapezoidal slip table of preventing is elastic rubber.

The utility model has the advantages that:

the utility model has the advantages of reasonable design, jack catch centre gripping contact surface is the capable structure of right angle V, can correspond the contact with square workpiece right angle department, is equipped with the trapezoidal slip table of preventing of being made by elastic rubber material on the V face, can effectively increase the frictional force of jack catch and work piece, avoids square workpiece to produce the removal man-hour inadequately because of the centre gripping dynamics, brings the hidden danger for the production safety, has reduced the wearing and tearing of square workpiece simultaneously, improves the accuracy that square workpiece adds man-hour, guarantee processingquality.

Detailed Description

The invention will now be described in further detail with reference to the accompanying drawings.

As shown in figure 1, the clamping jaw for the four-jaw chuck suitable for the square workpiece comprises a clamping jaw body 1, wherein a positioning concave hole 2 is formed in the bottom of the clamping jaw body 1, the positioning concave hole 2 and a positioning convex hole in a chuck groove 9 are fixed on the chuck in an interference fit mode, and the clamping jaw and the chuck are stable. 1 left side of jack catch body is centre gripping contact surface 3, be equipped with trapezoidal slip table 4 of preventing on the centre gripping contact surface 3, centre gripping contact surface 3 is right angle V type structure, can correspond the contact centre gripping with square workpiece right angle department, trapezoidal slip table 3 of preventing is elastic rubber, can effectively increase the frictional force of jack catch and work piece, avoids square workpiece to produce the removal because of the centre gripping dynamics is not enough when adding man-hour, brings the hidden danger for the production safety, has reduced the wearing and tearing to square workpiece simultaneously, improves the accuracy that square workpiece adds man-hour, ensures processingquality. The top of the body is provided with a first boss 5, a second boss 6 and a third boss 7.

Finally, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the present invention can be modified or replaced by other means without departing from the spirit and scope of the present invention, which should be construed as limited only by the appended claims.
