The mode of current processing blind hole is that the workman is earlier at 8 waiting of cylinder body drill hole positions draw points, be fixed in 8 frock of cylinder body on the three-jaw chuck, then rotatory three-jaw chuck makes 8 synchronous rotations of cylinder body, when observing that the point location of drawing on the cylinder body 8 is in the upright drill bit under, start upright drill, upright drill drives the drill bit rotation and is feed motion downwards, the drill bit is from drawing point location and drilling cylinder body 8 downwards, thereby process out the blind hole. However, although this machining method can machine a blind hole at a specified position on the cylindrical body 8, the following drawbacks still exist: I. the three-jaw chuck needs to be frequently rotated for multiple times to enable the drawn point position to move to the position right below the drill bit, which undoubtedly increases the positioning time, thereby reducing the production efficiency. II. Need additionally to draw the point, delayed the drilling time undoubtedly, further reduced production efficiency, in addition, the position of artifical drawing point is sometimes inaccurate, and then leads to the hole site dislocation of drilling to drilling quality has been reduced.

Detailed Description

The invention will be further described with reference to the accompanying drawings, without limiting the scope of the invention to the following:

as shown in fig. 3 to 5, a tool clamp for drilling a coupler comprises a vertical plate 1, wherein a positioning column a2 and a positioning column B3 are fixedly arranged on the front end surface of the vertical plate 1, the positioning column A2 and the positioning column B3 are arranged in an intersecting manner, the positioning column A2 is arranged right above the positioning column B3, the length of the positioning column A2 is smaller than that of the semi-finished coupler, the length of the positioning column A2 is larger than that of the positioning column B3, the outer diameter of the positioning column A2 is equal to the diameter of the center hole 9 of the semi-finished coupler, the outer diameter of the positioning column B3 is equal to the diameter of a circle A formed by two adjacent claws 10 on the semi-finished coupling, the front end face of the vertical plate 1 is fixedly provided with a rotary cylinder 4, the rotary cylinder 4 is perpendicular to the vertical plate 1, the rotary cylinder 4 is arranged right below the positioning column B3, a rotary arm 5 is fixedly arranged on a rotary shaft of the rotary cylinder 4, and the rotary arm 5 is arranged on the left side of the positioning column B3.

And a base is fixedly arranged on the rear end face of the vertical plate 1. And a nylon block 6 is fixedly arranged on the inner end surface of the rotating arm 5.

The working process of the utility model is as follows:

s1, sleeving a center hole 9 of the semi-finished coupler 7 on a positioning column A2 from front to back by a worker, and sleeving a circle A surrounded by any two adjacent claws 10 on the semi-finished coupler 7 on a positioning column B3; then, a worker pushes the semi-finished coupler 7 backwards to enable the front end face of the semi-finished coupler 7 to be abutted against the front end face of the vertical plate 1; then, the rotating cylinder 4 is operated to enable the rotating shaft to rotate for a certain angle, the rotating shaft drives the rotating arm 5 and the nylon block 6 to rotate, and after the nylon block 6 is in place, the nylon block 6 is in contact with the rear end face of the semi-finished coupler 7, so that the fixture of the rapid semi-finished coupler is fixed as shown in fig. 6-7;

s2, the worker operates the drill press to move the drill bit thereon from the top to the bottom to drill a blind hole in the cylindrical body 8 of the semi-finished coupling 7. The positioning column A2 and the positioning column B3 limit the circumferential movement of the semi-finished coupler, and the vertical plate 1 and the nylon block 6 limit the axial movement of the semi-finished coupler, so that the quick tool fixing of the semi-finished coupler is realized, a mode of fixing by adopting a three-jaw chuck is replaced, and the drilling efficiency is greatly improved; in addition, the same position of the semi-finished coupler can be ensured through the tool clamp, so that the same position of drilling on each semi-finished coupler is ensured, the consistency of products after drilling is improved, and the drilling quality is improved. In addition, drilling point positions do not need to be drawn on the semi-finished coupler, so that the labor intensity of workers is reduced, and the production efficiency is improved.
