Description

Technical Field

[0001] This utility model relates to a novel tool mounting structure and belongs to the field of leather processing technology. Background Technology

[0002] In the leather processing industry, various cutting tools are required. To adapt to different processing requirements, tools often need to be changed. Currently, tools are fixed by screws pressing against the side of the tool. This method requires a relatively large tightening force, making installation and replacement laborious and inconvenient. Existing technology (application number: CN201721864251X) discloses a tool mounting structure with screw holes on a tool mounting base (i.e., an integrated punch shaft). Bolts are screwed into these holes to lock the tool onto the mounting base. However, this existing technology has the following drawbacks: the orientation of the screw holes is uncertain after the punch shaft rotates. When the screw holes face inwards, there is insufficient space for operators to maneuver, making subsequent tool replacement or adjustment inconvenient. This is especially true when multiple punch shafts are connected in series, making it even more difficult to determine the orientation of the screw holes for each set of punch shafts, further complicating tool replacement and adjustment.

[0003] Therefore, the research objective of this utility model is to provide a tool mounting structure that allows for easy adjustment of the screw hole orientation to facilitate subsequent tool replacement or adjustment. Utility Model Content

[0004] To address the shortcomings of the aforementioned technologies, this utility model provides a novel tool mounting structure. The tool is locked and fixed to the punch shaft by a locking sleeve, and the locking sleeve is provided with an adjusting screw hole that matches the groove of the punch shaft, which facilitates the adjustment of the orientation of the locking screw hole on the locking sleeve and facilitates subsequent tool replacement or adjustment.

[0005] To solve the problems of the existing technology, the technical solution adopted by this utility model is as follows:

[0006] A novel tool mounting structure includes a punch shaft, a locking sleeve, and a tool. The punch shaft has an adjustable inner hole on its bottom inner side and a punch shaft groove along its circumference on its outer side. The locking sleeve has a locking screw hole for adjusting the tightness of the locking sleeve and an adjusting screw hole that penetrates its inner ring. The tool is inserted into the inner hole of the punch shaft for installation and locked in place by the locking sleeve. When locked, the position of the adjusting screw hole coincides with the position of the punch shaft groove.

[0007] Furthermore, the locking screw hole is used to lock the locking sleeve with a bolt, thereby locking the tool onto the punch shaft. The adjusting screw hole is connected to the punch shaft groove with a bolt.

[0008] Furthermore, the inner diameter of the adjusting screw hole is smaller than the inner diameter of the punch shaft groove.

[0009] Furthermore, the inner wall of the inner hole is provided with a retaining ring for limiting the cutting tool, and the retaining ring protrudes from the inner wall of the inner hole.

[0010] The beneficial effects of this utility model are: the tool is locked and fixed on the punch shaft by the locking sleeve, and the locking sleeve is provided with an adjusting screw hole that matches the groove of the punch shaft, which makes it easy to adjust the orientation of the locking screw hole on the locking sleeve, and facilitates the subsequent replacement or adjustment of the tool.

[0017] The components include: punch shaft 1, locking sleeve 2, cutting tool 3, inner hole 101, punch shaft groove 102, locking screw hole 201, adjusting screw hole 202, and retaining ring 103. Detailed Implementation

[0018] To enable those skilled in the art to better understand the technical solution of this utility model, the following description is provided in conjunction with the appendix. Figure 1-6 Further analysis of this utility model is then conducted.

[0019] like Figure 1-6 As shown, a novel tool mounting structure includes a punch 1, a locking sleeve 2, and a tool 3. The punch 1 has an adjustable inner hole 101 on the inner side of its bottom end and a punch groove 102 on its outer side along its circumference. The locking sleeve 2 has a locking screw hole 201 for adjusting the tightness of the locking sleeve 2, and an adjusting screw hole 202 penetrating its inner ring. The tool 3 is inserted into the inner hole 101 of the punch 1 for installation and is locked and fixed by the locking sleeve 2. When locked, the position of the adjusting screw hole 202 coincides with the position of the punch groove 102.

[0020] In this embodiment, preferably, the locking screw hole 201 is used to lock the locking sleeve 2 with a bolt, thereby locking the tool 3 onto the punch shaft 1, and the adjusting screw hole 202 is used to clamp the punch shaft groove 102 with a bolt.

[0021] In this embodiment, preferably, the inner diameter of the adjusting screw hole 202 is smaller than the inner diameter of the punch groove 102, so as to ensure that the bolt of the adjusting screw hole 202 can be clamped in the punch groove 102.

[0022] In this embodiment, preferably, the inner wall of the inner hole 101 is provided with a retaining ring 103 for limiting the cutting tool 3. The retaining ring 103 protrudes from the inner wall of the inner hole 101. When the cutting tool 3 is inserted into the inner hole 101, it means that the cutting tool 3 is installed in place when the cutting tool 3 reaches the retaining ring 103.

[0023] The working principle of this utility model is as follows: Before replacing or adjusting the tool 3, do not tighten the locking bolt in the locking screw hole 201. Instead, tighten the adjusting bolt in the adjusting screw hole 202 to fix the locking sleeve 2 onto the punch shaft 1. An external motor is used to connect multiple sets of punch shafts 1 in series and drive them to rotate. At this time, the locking sleeve 2 rotates with the punch shaft 1. When the punch shaft 1 stops rotating, the locking sleeve 2 also stops rotating. If the locking screw hole 201 on the locking sleeve 2 faces outwards from the equipment, there is enough space for the operator to tighten the locking sleeve 2. To facilitate subsequent tool replacement or adjustment, if the locking screw holes 201 on the locking sleeve 2 face inwards, there is insufficient space for workers to tighten the locking sleeve 2, hindering subsequent tool replacement or adjustment. Therefore, the adjusting bolt in the adjusting screw hole 202 should be loosened, and the locking sleeve 2 should be rotated so that all locking screw holes 201 of the locking sleeve 2 face outwards. Then, various tools 3 are installed into the inner hole 101 of the punch shaft 1, and the locking sleeve 2 is tightened using the locking bolt in the locking screw hole 202 to lock the tools 3 securely onto the punch shaft 1. When rotating the locking sleeve 2, only the adjusting bolt in the adjusting screw hole 202 needs to be loosened slightly. This allows the locking sleeve 2 to rotate while preventing it from falling off because the adjusting bolt is engaged in the punch shaft groove 102.

[0024] The technical solutions provided in this application have been described in detail above. The embodiments used in this document illustrate the principles and implementation methods of this application. The descriptions of the embodiments above are only for the purpose of helping to understand the methods and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
