Description

Technical Field

[0001] The utility model relates to the technical field of punch rod clamps, in particular to a three-dimensional clamp used for punch rod production. Background Art

[0002] After the punch rod is processed, it needs to be coated to improve its wear resistance, corrosion resistance and service life. During coating, it needs to be clamped and positioned by a fixture. Shaft heads are set at both ends of the fixture. The shaft heads are installed and rotated in coordination with the coating equipment to achieve uniform coating.

[0003] The current clamps usually drill a through hole on a metal tube that matches the diameter of the punch rod, and then set a bolt on the metal tube at a position corresponding to the through hole. When clamping, the punch rod is passed through the through hole, and then the bolt is tightened to press and fix the double-headed punch rod. Since it can only fix one punch rod at a time, its clamping and fixing efficiency is low.

[0004] Therefore, it is necessary to propose a three-dimensional fixture for punch production to solve the above problems. Utility Model Content

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0026] See also Figure 1-3As shown, a three-dimensional fixture for punch rod production includes: an end frame 5, there are two end frames 5, both sides of the end frames 5 are fixedly connected with screws 6; a clamping plate 1, there are two clamping plates 1, the two clamping plates 1 are symmetrically distributed between the two end frames 5 and fixedly connected with the end frames 5; a clamping assembly 2, there are two clamping assemblies 2, the clamping assembly 2 includes a clamping block 3 and a sliding rod 8, the sliding rod 8 is slidably connected to the end frame 5, the end of the sliding rod 8 is threadedly connected with a limiting nut 12, and a plurality of clamping blocks 3 are fixedly connected on both sides of the sliding rod 8, and the clamping blocks 3 on the two clamping assemblies 2 are symmetrically distributed for cooperating with the clamping plate 1 to clamp the workpiece.

[0027] When in use, the punch rod to be coated is placed between two symmetrical clamping blocks 3 on the two clamping assemblies 2. The punch rod is limited at three points by the two clamping blocks 3 and the clamping plate 1. At this time, the punch rod is in a pre-positioned state. After all the punch rods are placed, the limiting nut 12 at the end of the slide rod 8 is rotated to make the two slide rods 8 move relative to each other, so that the two symmetrical clamping blocks 3 on the two clamping assemblies 2 are close to each other, and the punch rod is positioned at three points with the cooperation of the clamping plate 1, thereby fixing the punch rod.

[0028] Specifically, both ends of the clamping plate 1 are fixedly connected to the screw rod 6 through positioning nuts 11, and the two clamping plates 1 are symmetrically distributed on both sides of the clamping assembly 2, and the clamping plates 1 and the slide rod 8 are parallel to each other. By adjusting the fixed position of the clamping plate 1 on the screw rod 6, the spacing between the two clamping plates 1 is controlled so that it can be adapted to the clamping of punches of different diameters. Specifically, the screw rod 6 passes through the clamping plate 1, and positioning nuts 11 are provided on both sides of the clamping plate 1.

[0029] In order to better limit the punch, a plurality of arc grooves 4 are provided along the length direction of the adjacent sides of the two clamping plates 1. Specifically, the clamping blocks 3 on the two clamping assemblies 2 are symmetrically distributed on both sides of the arc groove 4. By providing the arc groove 4, the placement position of the punch can be determined during the clamping positioning.

[0030] Due to the existence of errors, some punch rods may have unstable clamping problems. The clamping block 3 is fixedly connected to the sliding rod 8 through the elastic plate 9, so that the sliding rod 8 applies pressure to the clamping block 3 through the elastic plate 9 to compensate for the error and avoid some punch rods from loosening. The elastic plate 9 is fixedly connected to the connection between the elastic plate 9 and the sliding rod 8 with a support block 10. The support block 10 provides auxiliary support to the middle section of the elastic plate 9 to improve its structural strength.

[0031] Working principle: When in use, the punch rod to be coated is placed in the arc groove 4. The punch rod is limited at three points by two clamping blocks 3 and the clamping plate 1. At this time, the punch rod is in a pre-positioned state. After all the punch rods are placed, the limiting nut 12 at the end of the slide rod 8 is rotated to make the two slide rods 8 move relative to each other, so that the two symmetrical clamping blocks 3 on the two clamping assemblies 2 are close to each other, and the punch rod is positioned at three points with the cooperation of the clamping plate 1, thereby completing the positioning of the punch rod.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
