Clamp for central hole of sliding fork drilling end surface

Abstract

A clamp for a central hole of a sliding fork drilling end surface comprises a base plate; a support, a rotary disc, a left linear guide pair, a right linear guide pair and a power driving mechanism are arranged on the base plate; the rotary disc which is arranged on the base plate is arranged under the support; a positioning V-shaped block with the upward opening is connected to the support detachably; the left linear guide pair and the right linear guide pair are arranged on the left side and right side of the rotary disc; a left sliding block base is connected to the left linear guide pair in a sliding mode; a right sliding block base is connected to the right linear guide pair in a sliding mode; a left clamping V-shaped block is arranged on the right side of the left sliding block base; a right clamping V-shaped block is arranged on the left side of the right sliding block base; openings of the left clamping V-shaped block and the right clamping V-shaped block are oppositely formed; the power driving mechanism is in linkage with the rotary disc, the left sliding block base and the right sliding block base through the transmission mechanism. The clamp for the central hole of the sliding fork drilling end surface has the advantages of improving the product quality and labor intensity of workers, saving machining costs for parts, reducing labor intensity of the workers and reducing machining difficulties of tools.

Description

technical field [0001] The invention belongs to the technical field of machining, and in particular relates to a clamp for the center hole of the end face of a sliding fork drill. Background technique [0002] With the rapid development of my country's automobile industry, the auto parts manufacturing industry has been brought into the fast lane of rapid development. With the increasing maturity of its processing and manufacturing technology and the advancement of mechanical equipment technology, coupled with the application of a large number of numerical control equipment and the progress of specialized mass production, the competition in the field of auto parts processing has become more and more fierce, and it has entered the era of meager profits. At the same time, coupled with the increasing demand for price cuts from end customers and the cost transfer of main engine manufacturers, auto parts processing companies are forced to continue to innovate and improve, and aban...

AI Technical Summary

Problems solved by technology

This kind of fixture adopts the combination of screw and nut to drive and clamp the sliding fork. In the manufacturing process, the accuracy of the screw and the screw nut is strictly required, and the production is difficult (the processing process of the screw and the screw nut: 1. Quenched and tempered ; 2. Lead screw, wire mother gold processing; 3. Quenching treatment; 4. Lead screw, wire mother grinding processing), high cost

Moreover, the clamping method of this fixture is manual clamping. During the processing of parts, the labor intensity of workers is relatively high, and the processing efficiency is low.

In addition, this fixture lacks the positioning of the ear holes of the fork, which cannot ensure that the position of the two ears of the sliding fork is consistent with the outer circle after clamping, resulting in low accuracy of the central hole position of the processed part
