Description

Multi-function spacer

technical field

The utility model relates to a cushion block of mechanical fixtures, in particular to a height-adjustable cushion block which can be used in flat-nose pliers or machine tools.

Background technique

In mechanical cutting, it is a very common way to clamp parts with flat nose pliers. However, in practical applications, it is often encountered that some parts do not have suitable shims to raise the workpiece on the vise to the required height. At this time, only self-made shims can be used.

200910049619.0 discloses a method of using two relatively sliding slope parts to move relative to each other in the vertical direction of the bevel angle, so as to achieve the adjustment purpose of slightly adjusting the vertical height. The invention can only realize slight adjustments to the vertical height, and cannot process inclined surfaces, and the suitable processing conditions are relatively limited.

Utility model content

The technical problem to be solved by the utility model is: to provide a multi-functional spacer which is not only adjustable in height but also capable of processing inclined planes.

The technical solution adopted by the utility model to solve the technical problem is: a multifunctional cushion block, which has an upper backing plate, a sliding groove fixed on the bottom surface of the upper backing plate, a groove base, and a groove base parallel to the bottom surface of the groove base and penetrating through the The double-ended screw rods on the two vertical sides of the groove-shaped base and the first slider and the second slider respectively arranged on the positive and negative thread sections of the double-ended screw through the thread pair, the lower end of the first connecting rod is hinged on the second A slider, the upper end of which is slidably connected in the sliding groove; the upper end of the second connecting rod is hinged to the upper backing plate, and the lower end is hinged to the second slider; the first connecting rod and the second connecting rod are hinged to the connecting hole.

Specifically, a plurality of coupling holes can be processed on the first connecting rod or/and the second connecting rod; the second connecting rod includes two connecting rods parallel and arranged on both sides of the first connecting rod.

The beneficial effect of the utility model is that it solves the defects existing in the background technology, and solves the defect that the height cannot be adjusted by ordinary parallel irons through the adjustment of the height direction, and expands the scope of use; the utility model can be used to process required slopes.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

Fig. 1 is the structural representation of the preferred embodiment of the present utility model;

In the figure: 1. Upper backing plate; 2. Sliding groove; 3. Second connecting rod; 4. Grooved base; 5. First slider; 6. Connection hole; 7. First connecting rod; 8. Second Slide block; 9, double-ended screw rod.

Detailed ways

Now in conjunction with accompanying drawing and preferred embodiment the utility model is described in further detail. These drawings are all simplified schematic diagrams, and only schematically illustrate the basic structure of the utility model, so they only show the configurations related to the utility model.

A multi-functional spacer as shown in Figure 1 has a grooved base 4, an upper backing plate 1, a sliding groove 2 fixed on the bottom surface of the upper backing plate 1, parallel to the bottom surface of the grooved base 4 and runs through the grooved base 4. The double-ended screw rods 9 on the two vertical sides are respectively arranged on the first slider 5 and the second slider 8 on the positive and negative thread sections of the double-ended screw rod 9 through the thread pair, and the lower end of the first connecting rod 7 is hinged to the second A slider 5, the upper end is slidably connected in the sliding groove 2, the upper end of the second connecting rod 3 is hinged on the upper backing plate 1, the lower end is hinged on the second slider 8, the first connecting rod 7 and the second connecting rod 3 are hinged on the Connection hole 6. In order to be suitable for processing workpieces with inclined surfaces, a plurality of coupling holes 6 are provided on the first connecting rod 7 and/or the second connecting rod 3 . In order to improve the rigidity of the multifunctional spacer, the second connecting rod 3 includes two connecting rods arranged in parallel on both sides of the first connecting rod 7 .

The working principle of the utility model is as follows:

When the double-ended screw rod 9 is rotated, the first slide block 5 and the second slide block 8 complete the opposite or opposite movement, and at this moment, the upper backing plate 1 realizes the adjustment in the height direction.

If this utility model is only used in the horizontal plane processing of ordinary parts, the first connecting rod 7 and the second connecting rod 3 are hinged at the coupling hole 6 at the symmetrical center position of the first connecting rod 7 and the second connecting rod 3; Processing parts need to process inclined planes, and the first connecting rod 7 and the second connecting rod 3 hinged holes should select the connecting holes 6 on other positions on the first connecting rod 7 and the second connecting rod 3 .

What is described in the above specification is only the specific implementation of the present utility model, and various illustrations do not limit the essential content of the present utility model. Those of ordinary skill in the art can make specific implementations described before after reading the specification. modification or deformation without departing from the essence and scope of the utility model.
