Description

Clamping sleeve for large size tools

The invention relates to a clamping sleeve for cutting tools, particularly a clamping sleeve used for clamping and fixing large-sized cutting tools.

In order to reuse damaged tools to achieve environmental protection and cost-saving effects, the creator of this project has previously developed various grinding machines for various tools on the market, such as drill bits, milling cutters, and screw taps. These grinding machines generally have A motor that can drive a grinding wheel. At the same time, a plurality of grinding seats are provided on the circumference of the grinding wheel, so that the user can first hold the damaged tool through a clamping sleeve, and then wear it in sequence. On these grinding seats, the grinding wheel can be used to grind and repair the tool to restore the original performance of the tool.

However, with the increase in processing requirements, the size of existing tools is getting larger and larger. When the diameter is greater than 10 mm or the length is greater than 100 mm, the clamping sleeve will be unable to clamp the tool. Therefore, the creator of this project After observing the above shortcomings, I thought it was necessary to develop a clamping sleeve that can quickly and stably clamp the large-size tool to meet the grinding and repair needs of the large-size tool, and thus the present invention was born.

The purpose of this invention is to provide a holding sleeve for large-sized tools that can quickly and firmly hold large-sized tools so that the user can subsequently use a grinder to grind and repair the large-sized tools.

In order to achieve the above purpose, the present invention provides a holding sleeve for large-sized tools, which includes an outer sleeve. The outer sleeve has a first end and a second end that are oppositely arranged, and the third end is arranged oppositely. One end is provided with an accommodating hole toward the second end, and an inner sleeve is slidably provided in the accommodating hole. The inner sleeve is provided with a front end corresponding to the first end, and a front end corresponding to the second end. It is provided with a rear end, and the front end is penetrated with a fixing hole toward the rear end. At the same time, the inner sleeve is further provided with a clamping portion adjacent to the rear end. In addition, it also includes at least one tightening piece. It is provided on the outer sleeve and can be selectively pressed against the inner sleeve so that the inner sleeve cannot slide relative to the outer sleeve, and a positioning ring which is rotatably sleeved on the third One end, and the peripheral side of the positioning ring is provided with at least one positioning portion, and at least one positioning piece. The positioning piece is provided on the positioning ring and can selectively press against the outer sleeve to make the positioning The ring cannot rotate relative to this outer sleeve.

With the large-size tool clamping sleeve provided by this invention, the user only needs to insert the large-size tool into the fixing hole of the inner sleeve and clamp and fix it through the clamping part, so that the large-size tool cannot face each other. The inner sleeve rotates, and then the inner sleeve holding the large-size tool is inserted into the receiving hole of the outer sleeve, and the tightening parts are locked so that the inner sleeve cannot be relative to the outer sleeve Slide and finally rotate the positioning ring so that the positioning part is aligned with the blade of the large-size tool to complete the positioning, and lock the positioning piece to fix the position of the positioning ring, thereby quickly and firmly clamping the positioning ring. Large-sized tools so that the user can subsequently use a grinder to grind and repair the large-sized tools.

In order to further understand the structural characteristics of this creation, the use of technical means and the expected effects, the usage of this creation is described. I believe that this will lead to a more in-depth and specific understanding of this creation, as follows: Please refer to Chapter 1 Figures 5 and 6 are schematic exploded views and cross-sectional views of the preferred embodiment of the present invention. The holding sleeve 100 of the large-size tool is used to hold the large-size tool 200, wherein the large-size tool The tail end of the tool 200 is provided with a clamping section 201 that tapers outward, and the end of the clamping end 021 is extended with a square protrusion 202. When using the clamping sleeve 100 of the large-size tool When doing so, first insert the clamping section 201 of the large-size tool 200 into the fixing hole 23 of the inner sleeve 20, and let the bump 202 penetrate between the clamping blocks 241, so that the clamping section 201 can be inserted into the fixing hole 23 of the inner sleeve 20. The portion 24 clamps the bump 202 so that the large-size tool 200 cannot rotate relative to the inner sleeve 20. Then, the inner sleeve 20 holding the large-size tool 200 is clamped by the second end of the outer sleeve 10. 12 Penetrate into the accommodating hole 13, and slide and adjust the position of the inner sleeve 20 so that the head end of the large-size tool 200 penetrates the convex ring portion 15 for a certain distance, and then lock the tightening parts 30 so that The pressing parts 30 are pressed against the top surface 25 of the inner sleeve 20 so that the inner sleeve 20 cannot slide relative to the outer sleeve 10 , so that the head and tail of the large-sized tool 200 can be firmly fixed. , wherein the user can adjust the position of the pressing members 30 passing through the through holes 14 so that the pressing members 30 can be reliably pressed against the top plane 25 to prevent the inner sleeve 20 from being damaged. Rotate or move, and finally rotate the positioning ring 40 so that the positioning portion 41 is aligned with the blade of the large-size tool 200, and the position of the positioning ring 40 is tightly fixed through the positioning member 50, so that the positioning ring 40 can be quickly and firmly fixed. The large-sized tool 200 is fixed to the clamping sleeve 100 so that a grinder can be used to grind and repair the large-sized tool 200 later. The positioning method and grinding method of the large-sized tool 200 are common techniques, so here No more details.

Hereby, the characteristics of this creation and the expected effects it can achieve are stated as follows: With the large-size tool clamping sleeve 100 of this invention, the user only needs to insert the large-size tool 200 into the fixing hole 23 of the inner sleeve 20 and clamp and fix it through the clamping portion 24, so that the large-size tool 200 can be clamped and fixed. The tool 200 cannot rotate relative to the inner sleeve 20, and then the inner sleeve 20 holding the large-size tool 200 is inserted into the receiving hole 13 of the outer sleeve 10, and the tightening parts 30 are locked, so that The inner sleeve 20 cannot slide relative to the outer sleeve 10. Finally, the positioning ring 40 is rotated to align the positioning portion 41 with the blade of the large-size tool 200 to complete the positioning, and the positioning member 50 is locked to fix the positioning. The position of the ring 40 allows the large-sized tool 200 to be quickly and firmly clamped, so that the user can subsequently use a grinder to grind and repair the large-sized tool 200.

To sum up, this invention has excellent practicality among similar products. At the same time, after searching the technical information on this type of structure at home and abroad, no similar structure has been found to exist in the literature. Therefore, This invention actually meets the requirements for a new type of patent and an application must be filed in accordance with the law.

However, the above is only one of the best possible embodiments of this invention. Therefore, all equivalent structural changes made by applying the description of this invention and the patent application scope should be included in the patent scope of this invention.
