Description

Clamp apparatus

Technical Field

The utility model relates to the field of machinary, concretely relates to anchor clamps.

Background

In lathe processing, often need the anchor clamps to carry out the centre gripping to the part, some parts that have concave and convex face often carry out the centre gripping through three chucks, but traditional three chucks of grabbing directly contact with the outermost convex surface of part, and this face often causes the damage of this face for the machined surface easily, consequently it is very important to obtain the anchor clamps of a part that can protect the machined surface.

SUMMERY OF THE UTILITY MODEL

The utility model aims at the problems and provides a clamp which comprises a chuck, wherein more than two clamping pieces are fixed on the chuck; the clamping piece is characterized in that a groove body used for being fixedly installed with the chuck is arranged at the bottom of the clamping piece, a contact surface and a clamping surface are arranged on a clamping end of the clamping piece, and the clamping surface and the contact surface have a height difference.

Through above-mentioned technical scheme, because have the difference in height between clamping face and the contact surface, then be convenient for the part of centre gripping self having the concave-convex face, and can protect the convex surface of part.

As the preferable mode, a through hole for fixing is formed on the clamp with the upward groove body; the perforation is provided with a plurality of and is linear setting.

Through above-mentioned technical scheme, above-mentioned cell body and fenestrate setting up the setting into current folder, help it to install on the chuck.

As one preferable mode, three clamping pieces are arranged, and an included angle between every two adjacent clamping pieces is 120 degrees; the clamping surface is provided with an arc surface, and the arc surfaces of the three clamping pieces form a circle.

Through above-mentioned technical scheme, the cambered surface of part is helped protecting in being provided with of cambered surface, and adopts the minimum folder can clip columniform part.

As a preferable mode of the above, a magnetic member is provided at the center of the chuck to increase a clamping force to the clamped member.

Through above-mentioned technical scheme, the part by the centre gripping can help the axial absorption to the magnetism spare of setting, increases the stability of centre gripping.

Compared with the prior art, the utility model has the advantages of: because the height difference exists between the clamping surface and the contact surface, the part with the concave-convex surface is convenient to clamp, and the convex surface of the part can be protected; the cambered surface is arranged to help protect the cambered surface of the part, and the cylindrical part can be clamped by adopting a minimum clamping piece; the magnetic part can help the axial adsorption of the clamped parts, and the clamping stability is improved.

Detailed Description

As shown in fig. 4, a conventional fixture, which clamps directly on the convex surface of the part, may damage the convex surface that has just been machined.

Referring to the attached drawings, the utility model adopts the following technical scheme that the clamp comprises a chuck, wherein more than two clamping pieces are fixed on the chuck; the bottom of the clamping piece is provided with a groove body used for being fixedly installed with the chuck, a contact surface and a clamping surface are arranged on a clamping end of the clamping piece, and the clamping surface and the contact surface have a height difference; because the height difference exists between the clamping surface and the contact surface, the part with the concave-convex surface can be conveniently clamped, and the convex surface of the part can be protected.

A through hole for fixing is formed on the clamp with the upward groove body; a plurality of through holes are arranged in a linear manner; the groove body and the through hole are arranged in the conventional clamping piece, so that the clamping piece is favorably arranged on the chuck.

The number of the clamping pieces is three, and the included angle between every two adjacent clamping pieces is 120 degrees; the clamping surface is provided with an arc surface, and the arc surfaces of the three clamping pieces form a circle; the cambered surface is provided with the cambered surface that helps protect the part, and adopts minimum folder can clip cylindrical part.

Wherein the center of chuck is provided with magnetic part for increase to the clamping power of being held the part, the magnetic part of setting can help the axial to adsorb the part by the centre gripping, increases the stability of centre gripping. The center of the chuck is provided with a downward groove which is glued with a magnetic part.

Wherein the folder is the design of integrated into one piece's mode, and the chuck is current chuck, fixes on the chuck through the perforation.

In order to better understand the invention for those skilled in the art and to define the claimed scope more clearly, the invention will be described in detail below with respect to certain specific embodiments of the invention. It should be noted that the following description is only a few examples of the present invention, and the specific and direct descriptions of the related structures are only for the convenience of understanding the present invention, and the specific features do not naturally and directly limit the scope of the present invention.
