Description

A flip-type drilling jig

technical field

The utility model belongs to the technical field of mechanical processing and relates to a processing fixture, in particular to a flip-type drilling fixture.

Background technique

In some industrial productions, it is often necessary to process and drill workpieces, and manual clamping is generally used. During processing, first fix the workpiece to be processed on the fixture, and after the workpiece is clamped, the worker manually flips the fixture over, and then performs drilling on the supported surface, which requires turning over the clamped workpiece , processed on the back side. When the volume and weight of the workpiece to be processed is very large, it not only consumes the physical strength of the operator during the turning process, but also has the disadvantage of low work efficiency.

In order to solve the above-mentioned defects existing in the existing drilling jig, the utility model develops a flip-type drilling jig.

Contents of the invention

The utility model provides a flip-type drilling jig to solve the problems of low working efficiency and high labor intensity in the existing drilling jig.

The utility model is achieved through the following technical solutions:

A flip-type drilling jig is characterized in that it includes a drilling template, a counterweight, a positioning pin, a rotating shaft bracket, and a support frame. One end of the workbench is provided with a rotating shaft, and the drilling template is fixed on the rotating shaft bracket through the rotating shaft. The support frame is fixed below the other end of the drilling template; the counterweight is fixed at both ends of the rotating shaft; the drilling template is provided with a positioning hole, and when the drilling template rotates around the rotating shaft, the position of the positioning hole and the positioning pin Compatible; the drill template is arranged with a drill sleeve and a pressure plate.

Further, the workbench is provided with an operating handle, and when rotating, the workbench can be rotated around the axis of rotation only by pulling the handle slightly.

The counterweight is an arc-shaped counterweight, that is, the upper and lower ends of the counterweight are cross-sections, and the sides are arc-shaped. When turned over, the arc-shaped surface rotates along the horizontal plane, which can save the operator's strength and reduce labor intensity.

In summary, the utility model has a simple structure and an ingenious design, which can effectively reduce labor intensity and improve work efficiency.

Description of drawings

Fig. 1 is the structural representation of the utility model;

Among the figure: 1-drill template, 2-rotating shaft support, 3-support frame, 4-counterweight, 5-locating pin, 6-rotating shaft, 10-locating hole, 11-workpiece.

detailed description

In order to make the purpose, technical solutions and advantages of the utility model clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments.

A kind of overturn type drilling jig as shown in Figure 1 is characterized in that, comprises drilling template 1, counterweight 4, positioning pin 5, rotating shaft bracket 2, support frame 3, and one end of described drilling template 1 is provided with Rotating shaft 6, the drilling template 1 is fixed on the rotating shaft support 2 through the rotating shaft 6, and the support frame 3 is fixed below the other end of the drilling template 1; the counterweight 4 is fixed on the two ends of the rotating shaft 6; the drilling template 1 A positioning hole 10 is opened on it, and when the drilling template 1 rotates around the rotating shaft 6, the positioning hole 10 matches the position of the positioning pin 5; the drilling template 1 is provided with a drill sleeve 7 and a pressing plate 8.

During use, the positioning hole 10 on the drilling template and the contacting position of the positioning pin 5 fix the workpiece 11 on the drilling template 1 through the pressing plate 8, and by pulling the operating handle 9 arranged on the drilling template 1, the arc counterweight Under the action of the block 4, the workman only needs a small amount of effort to easily turn over the fixture, and when the other end of the drill template falls on the support frame 3, the workpiece is drilled through the position of the drill sleeve.
