Detailed ways

The specific embodiment of the specific scheme of the utility model is further elaborated in conjunction with the accompanying drawings.

A square pipe drilling jig device, comprising a base 1, a jig 2, a first bearing 3 and a second bearing 4, the first bearing 3 and the second bearing 4 are all provided with a bearing seat 16, and the bearing seat 16 is installed On the base 1, the first bearing 3 and the second bearing 4 are arranged facing each other and the clamp 2 is connected to the front, and the back of the second bearing 4 is connected to a pressing mechanism 5, and the pressing mechanism 5 is installed on the base 1 Above, the clamp 2 is used to clamp the square pipe 6, and the bearing drives the clamp 2 to rotate. Square tubes can be parts of chairs, electric chairs, lift tables, etc., and need to be drilled on multiple sides.

The bearing drives the clamp 2 to rotate 90 degrees at a time. When one surface is drilled, rotate it 90 degrees to drill the next surface.

The clamp 2 includes a spring pin 7 and a pushing mechanism. A clamp groove 8 is provided inside the clamp 2. The clamp groove 8 is a rectangular groove, which matches the shape of the square tube 6 to achieve the best space utilization.

The front part of the spring pin 7 penetrates the clamp groove 8 from the side of the clamp 2, and the side of the clamp 2 is provided with a pushing mechanism that matches the rear of the spring pin 7, and the pushing mechanism pushes the spring pin 7 for Loosen square tube 6.

The spring pins 7 are arranged on the side and the top of the clamp 2, and each of the spring pins 7 is provided with a pushing mechanism. The arrangement of the upper side and the side makes the square tube 6 rest in the clamp groove 8 by its own gravity, and can also be clamped in two dimensions, which is reinforced and stable, and cooperates with the gravity, and the clamping direction is set reasonably.

The pushing mechanism includes a cylinder 9 and a pushing block 10 connected to the front end of the cylinder 9 , the pushing block 10 is provided with a pushing slope, and the pushing slope cooperates with the rear part of the spring pin 7 to pull the spring pin 7 apart. The pushing block 10 is a triangle as shown in the figure, and it can also be a pushing block 10 of other shapes with a pushing slope.

The spring pin 7 includes a splint 11 installed at the front end, and the splint 11 is a rectangular clip. The rectangular clip can fit the square tube 6 and is evenly stressed. The shape of the clip can also be a circle, a rhombus, etc., and the more commonly used one is a rectangle.

The spring pin 7 is a broken-line elbow with a splint 11 at the front end. One end of the spring 13 in the spring pin 7 is connected to the wall of the fixture groove 8, and the other end is connected to the rear of the splint 11.

When the pushing mechanism is not pushed forward, the spring 13 is free to stretch, so that the spring pin 7 stretches forward against the square tube 6. When the pushing mechanism pushes, the pushing block 10 pulls the spring pin 7 to the outside of the clamp 2, even if the spring 13 After compression, the square tube 6 is loosened, and the operation of loading or unloading can be carried out at this time.

A compression spring 12 is provided in the middle of the pressing mechanism 5 , and the compression spring 12 is connected to the rear of the second bearing 4 . It is used to press against the square pipe 6 in the horizontal direction, and cooperates with the clamp 2 to form a three-dimensional clamping. The multi-dimensional clamping makes the square pipe 6 very stable, not easy to shake, and drills accurately.
