Description

Technical Field

[0001] The utility model relates to the technical field of drilling processing, in particular to a drilling positioning fixture. Background Art

[0002] Drilling refers to the operation of drilling holes in solid materials with a drill. When drilling a bearing seat, a positioning fixture is needed to position and fix the bearing seat so that the bearing seat can be fixed in a specified position for accurate drilling.

[0003] When the existing bearing seat drilling and positioning fixture is used to position and fix the bearing seat, the bearing seat is subjected to greater friction when it is moved and positioned, making it difficult to move and position. At the same time, the bearing seat drilling and positioning fixture is basically driven by a cylinder and does not have the ability of self-locking. When the cylinder is powered off or fails, the fixture is prone to loosening.

[0004] To this end, we propose a drilling positioning fixture. Utility Model Content

[0015] Beneficial Effects

[0016] The utility model provides a drilling positioning fixture, which has the following beneficial effects:

[0017] (1) This drilling positioning fixture is provided with a slide rail, a sleeve and an automatic positioning clamping mechanism. The automatic positioning clamping mechanism drives the bearing seat to move to the sleeve for clamping, and the bearing seat is positioned by the V-shaped clamping block on the automatic positioning clamping mechanism. The bearing seat is positioned by moving on the slide rail through the sleeve, thereby improving the smoothness of the positioning movement of the bearing seat. At the same time, the first screw rod and the second screw rod on the automatic positioning clamping mechanism enable the entire automatic positioning clamping mechanism to have a self-locking ability, thereby avoiding the automatic positioning clamping mechanism from loosening in the event of a power outage.
