Problems solved by technology

[0004] However, there is a defect in this structure, that is, the clamping force received by the inner and outer ends of the workpiece is different, and the clamping force at the outer end where the processing end is located is smaller than the inner end, so when the workpiece is processed, it is easy to shake, resulting in The processing accuracy of the product is reduced, and the scrap rate is greatly increased, thereby increasing the cost input of the enterprise, and the structure also has the disadvantages of time-consuming clamping and loosening process and long operation cycle

Embodiment

[0022] Example: Reference figure 1 , figure 2 and image 3 , the workpiece clamping device in this embodiment includes an organic base 13, a body 1, a drive mechanism 18 that can make the body 1 move back and forth relative to the base 13, and an adjustment mechanism for quickly positioning the workpiece 10.

[0023] The base 13 has a hole for inserting the main body 1 therein, and the hole on the base 13 has an inner tapered surface 16 matched with the outer tapered surface of the main body joint 14 at the front end corresponding to the main body joint 15 .

[0024] The main body 1 is in the shape of a column with a thicker front end 11 and a thinner rear end 12, and has a through central cavity. The rear end 12 is inserted in the hole on the base 13, and the front end 11 of the body is larger than the hole on the base 13 and exposed outside the hole of the base 13 because of its outer diameter, and the front end 11 of the body is along the The outer wall has at least two...

Abstract

The invention relates to a work-piece clamper, which comprises: a base with a hole inserted by main body; a main body whose front end is thick and back end is thin, with a through hollow chamber, while the back end is inserted into the hole of base; at least two radial longitudinal grooves along the outer wall of front end; and a driver that moves main body front and back relative to the base; the inner wall of front end of main body has at least two compressing blocks uniformly distributed along the circumference. Compared with present technique, the invention can machine kinds of small work pieces, with better clamping effect and high accuracy, without deflecting the work piece.

Description

technical field [0001] The invention relates to a clamping device, in particular to a workpiece clamping device applied in mechanical processing. Background technique [0002] There are various types of existing clamping devices used in mechanical processing, and each has its own strengths. When making the bubble workpiece of the spirit level, the existing clamping device has a structure including a base, a body and a driving mechanism that can make the body move back and forth relative to the base. The base has a hole that can accommodate the body to be inserted therein. The main body is in the shape of a column with a thicker front end and a thinner rear end, and has a through central cavity. In the hole on the base, and the front end of the body is exposed outside the base hole because its outer diameter is larger than the hole on the base, and the front end of the body has at least two radially arranged longitudinal Slots, these longitudinal slots extend all the way ba...
