Description

Technical Field

[0001] The present application relates to the technical field of building construction, and in particular to a die clamp for threading anchor bolts. Background Art

[0002] The die, commonly known as the "screw hinge plate", is a thread tool used to process external threads. In petrochemical construction, because the anchor bolts are professionally constructed for civil engineering, the threaded part of the anchor bolts is often higher during construction, resulting in the inability to install the nuts of the equipment and structures in place and tighten them. Due to limited space and avoiding breaking the foundation, the anchor bolts can only be threaded on site to make the threaded part meet the requirements for installing equipment and structures. For this reason, the inventor proposed a die fixture for threading anchor bolts. Utility Model Content

[0003] The purpose of the present application is to provide a die clamp for threading anchor bolts, which can achieve rapid fixation of dies with different outer diameters and has the advantage of easy operation.

[0033] Example 1

[0034] See also Figure 1-Figure 3The present embodiment provides a die clamp for threading an anchor bolt, which is used to quickly fix the die 50 so as to implement the threading operation on the anchor bolt using the die 50.

[0035] In this embodiment, the die clamp for threading anchor bolts includes a support portion 12 formed at the lower end of a cylinder body 10, the outer diameter of the support portion 12 is larger than the outer diameter of the cylinder body 10, a plurality of positioning rods 40 evenly distributed along the circumferential direction are screwed on the support portion 12, the inner end of the positioning rod 40 is inserted into the positioning hole 51 on the circumferential surface of the die 50, and an adjusting cylinder 30 is rotatably clamped on the support portion 12, and the lower end of the adjusting cylinder 30 is engaged with the positioning rod 40.

[0036] This embodiment utilizes the meshing cooperation between the adjustment cylinder 30 and the positioning rod 40. Rotating the adjustment cylinder 30 can drive multiple positioning rods 40 to synchronously rotate toward the inside of the cylinder body 10 until the positioning rod 40 is inserted into the positioning hole 51 on the die 50, thereby achieving rapid fixation of the die 50. It has the advantages of wide application range and easy operation.

[0037] Specifically, the barrel 10 is constructed as a whole into a cylindrical shape with both ends connected. The support portion 12 is integrally formed at the lower end of the barrel 10, and the support portion 12 and the barrel 10 are coaxially arranged. The outer diameter of the support portion 12 is larger than the outer diameter of the barrel 10, and the inner diameter of the support portion 12 is equal to the inner diameter of the barrel 10. A circular ring-shaped slide groove 13 is provided at the top of the support portion 12, and the slide groove 13 and the support portion 12 are coaxially arranged. A limit plate 20 is also screwed on the barrel 10 above the support portion 12. In order to facilitate the rotation of the barrel 10, a clamping groove 11 is also provided on the top of the barrel 10. Four clamping grooves 11 are evenly arranged along the circumference of the barrel 10, which is convenient for clamping the cross-shaped handle on the barrel 10. Pushing the handle can facilitate the rotation of the barrel 10.

[0038] In addition, the adjusting cylinder 30 is constructed as a whole into a cylindrical shape that is adapted to the outer shape of the support portion 12. The adjusting cylinder 30 is entirely sleeved on the outside of the support portion 12. The adjusting cylinder 30 and the support portion 12 are coaxially arranged, and a cylindrical clamping plate 31 is provided on the top of the adjusting cylinder 30. The clamping plate 31 and the adjusting cylinder 30 are coaxially arranged, and the clamping plate 31 is entirely located inside the adjusting cylinder 30. The clamping plate 31 is entirely rotatably clamped in the slide groove 13 at the top of the support portion 12, and the limiting plate 20 is blocked at the top of the adjusting cylinder 30, so as to rotatably limit the adjusting cylinder 30 as a whole on the support portion 12.

[0039] It should be noted that teeth are provided at the lower end of the adjusting cylinder 30 , and the teeth are arranged around the circumference of the adjusting cylinder 30 , and are in meshing transmission connection with the positioning rod 40 therebelow.

[0040] In addition, the positioning rod 40 is arranged as a whole along the radial direction of the cylinder body 10. The positioning rod 40 includes a threaded section 41 and a tooth section 42. The threaded section 41 is screwed onto the support portion 12, and the inner end of the threaded section 41 can be inserted into the positioning hole 51 on the peripheral surface of the die 50. The die 50 is arranged as a whole inside the support portion 12 and maintains a coaxial arrangement with the support portion 12. The tooth section 42 extends to the outside of the support portion 12 and maintains engagement with the teeth on the lower end surface of the adjustment cylinder 30.

[0041] When in use, first place the die 50 into the support part 12, then rotate the adjusting cylinder 30, and use the meshing transmission connection between the adjusting cylinder 30 and the positioning rod 40 to make the positioning rod 40 screw into the inside of the support part 12 until the inner end of the positioning rod 40 extends into the bottom of the positioning hole 51 on the peripheral surface of the die 50. Since each positioning rod 40 moves synchronously driven by the adjusting cylinder 30, it can be ensured that the distance moved into the interior of the support part 12 by each positioning rod 40 is the same, thereby ensuring that the die 50 can be coaxially arranged with the cylinder body 10, and then the die 50 is inserted into the anchor bolt. Finally, the worker rotates the cross-shaped handle in the slot 11 clamped on the top of the cylinder body 10 to drive the die 50 to screw into the anchor bolt, thereby completing the threading operation of the anchor bolt.

[0042] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present application. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present application.
