Embodiment Construction

[0010] The specific embodiment of the present invention is described below:

[0011] see figure 1 , a fixture for locating parts 2 that require high perpendicularity between the axis line of the hole 21 and the plane 22, it includes a fixture base 10, a fixture fixed on the fixture base 10 and the described The insertion rod 11 matched with the hole 21 , the first support seat 12 and the second support seat 13 provided on the fixture base 10 for positioning the component 2 along the extending direction of the insertion rod 11 . The insertion rod 11, the first support seat 12, and the second support seat 13 are distributed along the length direction of the part 2, and the first support seat 12 is located on the back of the plane 22, the The second support seat 13 is located at the end of the component 2 far away from the hole 21 . The positioning surfaces of the first support base 12 and the second support base 13 are set so that they can be raised and lowered relative to the...

Abstract

The invention relates to a clamp and a positioning mode thereof. The clamp comprises a clamp base, an inserted rod which is fixed on the clamp base and is matched with the hole, first and second supports which are arranged on the clamp base and used for positioning a part in an extension direction of the inserted rod, wherein the positioning faces of the first and second supports are arranged in a way of being capable of lifting relative to the clamp base. The positioning model of the clamp is first to position a part by the inserted rod and one support and then to adjust the other support to the positioning face of the previous support to contact with the part. Supported by the two supports, the part is insusceptible to deflection caused by a processing force during processing, so the processing precision of the part can be improved.

Description

technical field [0001] The invention relates to a fixture and a positioning method thereof, which are used for positioning parts that require high perpendicularity between the axis line of a hole and a plane. Background technique [0002] see figure 1 As shown in the part, one end of the part has a hole, and the part requires that a certain plane of the part has a higher perpendicularity relative to the axis of the hole. The existing fixtures for positioning this kind of parts generally include an insertion rod for positioning the above-mentioned holes and a support base for positioning the above-mentioned plane. In the actual production process, it is found that the positioning effect of the existing fixture is not ideal. When the parts are processed, due to the inevitable existence of processing force, the parts are easy to shift. Contents of the invention [0003] The technical problem to be solved by the invention is to improve the existing fixture to improve the pos...
