Technical Field

The utility model belongs to the machining field especially relates to an inclined plane spot facing work device.

Background

Among machining processes, hole machining is a very common machining process. With the development of times and the progress of science and technology, the processing of inclined holes is more and more common. Inclined holes are drilled in a variety of ways, and generally include drilling holes in inclined planes, drilling holes in flat planes, drilling holes in curved surfaces, and the like. They have in common the problem that the axis of the hole and the end face of the drilled hole are not perpendicular, which results in a single side stress on the drill bit, which can cause the drill bit to shift to one side, which not only makes the positioning of the drill bit inaccurate but also makes the verticality of the drilled hole not meet the specified requirements, and there is a great possibility of breaking the drill bit.

The utility model discloses a solve the problem of inclined plane spot facing work, the utility model provides a can angle of adjustment bore inclined hole anchor clamps, which comprises a base, be equipped with convex guide rail on the base, it is equipped with the slider to slide in the guide rail, be equipped with the guide way on the slider, it is equipped with the grip block to slide in the guide way, the grip block passes through the spring and slides and set up in the guide way, still fix on the slider and be equipped with the baffle, the base outside is equipped with the scale.

Furthermore, the guide rail is a dovetail guide rail, and the sliding block is also provided with a dovetail groove matched with the dovetail guide rail. By adopting the dovetail groove structure, the sliding is more reliable, the sliding position is more accurate, and the corresponding measurement precision is higher.

Preferably, the bottom of the slider corresponds to the shape of the guide rail for facilitating sliding.

Furthermore, a sliding groove is formed in the base, an installation plate is fixed on the sliding block, a positioning bolt is fixed on the installation plate, the positioning bolt is arranged in the sliding groove in a sliding mode through the spring, and the distance between the two positioning plates is smaller than the nominal diameter of the positioning bolt. Positioning bolt on the mounting panel slides in the spout to the drive the mounting panel slides, the mounting panel drives the slider slides, satisfies the location that the work piece needs.

Preferably, the two sides of the sliding groove extend inwards to form positioning plates, one end of each positioning bolt is arranged in the sliding groove, and the other end of each positioning bolt is matched and locked with a nut. The positioning plate limits the positioning bolt to slide out of the sliding groove, and the nut is screwed down and used for locking the sliding block.

Has the advantages that: (1) the utility model relates to a can angle regulation's brill inclined hole anchor clamps, angle adjustment board can be adjusted at 0-90, strong adaptability, and the precision is high.

(2) The utility model relates to a drilling inclined hole anchor clamps that can angle of adjustment adopts the structure of dovetail and forked tail guide rail, can make to slide more reliable, and the sliding position is also more accurate, and corresponding measurement accuracy also more increases.

(3) The utility model relates to a can angle of adjustment bore inclined hole anchor clamps, when processing a batch of the same work piece, only need will treat that the work piece is appropriate to be installed on angle adjustment bench, then only need angle adjustment bench adjustment angle, the back is accomplished in spot facing work, only needs to lift the work piece of accomplishing of processing off, another is changed and is treated the processing work piece, continue processing can, save time and simplified operation process by a wide margin.

Detailed Description

As shown in fig. 1, an angle-adjustable inclined hole drilling fixture comprises a base 1, wherein a circular arc-shaped guide rail is arranged on the base 1, a sliding block 6 is arranged on the guide rail in a sliding manner, the bottom of the sliding block 6 corresponds to the shape of the guide rail, the guide rail is a dovetail guide rail 12, the sliding block 6 is further provided with a dovetail groove 11 matched with the dovetail guide rail 12, and the dovetail groove 11 is of a dovetail groove 11 structure, so that the sliding is more reliable, the sliding position is more accurate, and the corresponding measurement precision is higher. Be equipped with guide way 10 on the slider 6, it is equipped with grip block 3 to slide in the guide way 10, grip block 3 slides through the spring and sets up in the guide way 10, still fixed baffle 5 that is equipped with on the slider 6, the 1 outside of base is equipped with scale 7.

As shown in fig. 2, a sliding groove 2 is further formed in the base 1, an installation plate 14 is fixed on the sliding block 6, a positioning bolt 8 is fixed on the installation plate 14, the positioning bolt 8 is slidably arranged in the sliding groove 2 through a spring, the spring drives the positioning bolt 8 to push the sliding block 6 to move, and the distance between the two positioning plates 13 is smaller than the nominal diameter of the positioning bolt 8. The two sides of the sliding groove 2 extend inwards to form positioning plates 13, one end of each positioning bolt 8 is arranged in the sliding groove 2, and the other end of each positioning bolt is matched and locked with a nut 15. The positioning plate 13 limits the positioning bolt 8 in the sliding groove 2, and the nut 15 is used for locking the sliding block 6.
