Sliding block type drilling/tapping fixture frame

Abstract

The invention discloses a sliding block type drilling / tapping fixture frame. According to the fixture frame, parts are placed on a drilling / tapping platform, the horizontal position of the drilling / tapping platform can be wholly adjusted through adjustment of a sliding block, a rectangular guideway can be adjusted to drive the sliding block to move so as to adjust the longitudinal position of the drilling / tapping platform, rectangular linear guide set mechanisms are adopted on a left and right longitudinally adjustable rectangular guide set device and a transversally adjustable rectangular guide set device, the size of a track can be adjusted timely according to the size of a guide rail, locating accuracy and transmission stability of guide sets can be effectively guaranteed, therefore the high accuracy requirement for the guide rail during usage is satisfied, and a supporting plate arranged at the bottom of a base can provide sufficient friction for the sliding block in drilling / tapping processes so as to prevent the sliding block from slipping. The fixture frame has the advantages of being simple in structure, flexible and rapid in drilling and tapping, small in kinetic and static friction coefficients, good in rigidity, large in carrying capacity, high in locating accuracy and stable in transmission.

Description

technical field [0001] The invention relates to a guide rail auxiliary device, in particular to a slider type drilling / tapping fixture frame. Background technique [0002] At present, generally in the process of drilling / tapping, it is necessary to use the corresponding fixture to realize the positioning of the parts and the fastening function during the processing. However, some small parts are often encountered in the finishing process of the parts. It needs to be drilled or tapped. On a general drilling machine, it is difficult to realize the positioning and fastening of such workpieces through its inherent fixtures. The hands cannot grasp the parts at all. The movement in the process directly affects the processing accuracy of the parts, and it is not safe to process the parts by hand. Therefore, it is necessary to have an auxiliary fixture that can accurately position the parts on the drilling machine. [0003] At present, the auxiliary fixtures on the market basically...
