Description

Shift adjusting mechanism

Technical Field

The utility model relates to a shift and adjust technical field, especially relate to a mechanism that shift adjustment was used is carried out to work piece or spare part in single dimension direction.

Background

In production work, the distance between two adjacent workpieces A and B is often required to be adjusted according to production work requirements. Currently, the commonly used adjustment methods are as follows:

1. utilize two adjacent work pieces A of bolted connection and B, make the direct jack-up of bolt need the work piece A of relative regulation to carry on spacingly to the work piece A that needs relative regulation through the notch, and drive work piece A and remove in single dimension direction through revolving the spiral shell bolt during the regulation. Thus, although the adjustment can be completed, at least two screwing bolts are needed to ensure the adjustment stability, the adjustment is not convenient, the space occupation is large, and the use is inconvenient.

2. And a regulating gasket is directly arranged between two adjacent workpieces A and B. Therefore, in order to deal with different adjustment heights, a plurality of sets of adjusting gaskets need to be prepared, and when the adjustment height is not fixed, the adjustment requirement cannot be met.

SUMMERY OF THE UTILITY MODEL

In order to reduce the occupied space, simplify the adjustment operation and improve the adjustment precision, the utility model provides a displacement adjusting mechanism, which comprises a base, an adjusting bolt, a wedge block and a sliding block, wherein the base is provided with an adjusting groove, and the side wall of the adjusting groove is provided with an adjusting through hole; the adjusting bolt is arranged in the adjusting through hole, and an adjusting head of the adjusting bolt extends into the adjusting groove; the wedge block is positioned in the adjusting groove and connected with the adjusting head of the adjusting bolt, and the wedge block can slide in the adjusting groove along the axial direction of the adjusting bolt under the driving of the adjusting bolt; the sliding block presses the adjusting surface of the wedge block to form an inclined surface and presses the inclined surface on the top of the wedge block.

When the displacement adjusting mechanism of the utility model is used for carrying out displacement adjustment in a single dimension direction on a workpiece to be adjusted, the displacement adjusting mechanism of the utility model is firstly arranged between two adjacent workpieces, wherein, the base is connected with the fixed workpiece, and the sliding block is connected with the workpiece to be adjusted; then, pushing the adjusting bolt in the longitudinal direction, namely the axial direction of the adjusting bolt, in a screwing mode, so that the adjusting bolt transversely pushes the wedge block to drive the sliding block to move upwards in the longitudinal direction until the workpiece to be adjusted reaches a preset position; and finally, the wedge block can be pulled back in a reverse screwing mode, so that the sliding block falls back to a set position under the action of gravity. Therefore, when the displacement adjusting mechanism of the utility model is used for carrying out displacement adjustment on a workpiece to be adjusted in a single dimension direction, only one adjusting bolt needs to be pushed or pulled back in a screwing mode, the operation is simple and convenient, and the space occupation ratio is small; in addition, the adjusting bolt is pushed to adjust the distance between the sliding block and the base in a screwing mode, stepless adjustment can be achieved, and adjusting precision is high.

Preferably, a guide through hole for installing a guide rod is formed in the bottom wall of the adjusting groove, and the guide through hole is positioned on two sides of the wedge block; and a guide blind hole for accommodating the guide end of the guide rod is arranged at the position, corresponding to the guide through hole, on the sliding block. Like this, in accommodation process, can utilize the guide bar to carry out the direction control to the regulation direction of sliding block, avoid the sliding block to take place the dislocation in accommodation process, influence regulation effect. Furthermore, the guide rods are symmetrically arranged on two sides of the adjusting bolt. Thus, the stability of the displacement direction of the slide block during adjustment can be further improved. Preferably, the two ends of the sliding block are provided with support blocks for distributing the guide blind holes, and the support blocks are located on two sides of the wedge block and extend to the bottom wall of the adjusting groove. Like this, both can increase the degree of depth of direction blind hole, improve direction stability, can reduce the clearance between the diapire of sliding block and adjustment tank again, reduce the power that the guide bar probably bore at the direction in-process, avoid the guide bar impaired because of the atress is too big.

Preferably, an adjusting head of the adjusting bolt is fixedly connected with the wedge block, an adjusting threaded sleeve is sleeved on the adjusting bolt, and the adjusting threaded sleeve abuts against the outer wall of the adjusting groove. Therefore, in the adjusting process, the adjusting speed and the adjusting effect can be prevented from being influenced by the fact that the adjusting bolt, particularly the adjusting head, shakes.

Preferably, the top of the sliding block is provided with a connecting screw hole. Like this, when being connected the sliding block with treating the regulation work piece, can adopt bolted connection, convenient and fast, and quick detachable.

Detailed Description

The following describes the displacement adjusting mechanism of the present invention in detail with reference to fig. 1 to 4.

As shown in fig. 1-4, the displacement adjusting mechanism of the present invention comprises a base 1, an adjusting bolt 2, a wedge 3 and a sliding block 4. Wherein. The base 1 is provided with an adjusting groove 11, and the side wall 12 of the adjusting groove 11 is provided with an adjusting through hole 121. The adjusting bolt 2 is installed in the adjusting through hole 121, and the adjusting head 21 of the adjusting bolt 2 protrudes into the adjusting groove 11. The wedge block 3 is positioned in the adjusting groove 11 and is connected with an adjusting head 21 of the adjusting bolt 2, and the wedge block 3 can slide in the adjusting groove 11 along the axial direction of the adjusting bolt 2 under the driving of the adjusting bolt 2; the adjusting surface of the slide 4 pressed towards the wedge 3 is arranged as an inclined surface and pressed against the top inclined surface of the wedge 3.
