Description

Technical Field

[0001] The utility model belongs to the technical field of metal workpiece cutting and processing, in particular to a split-type CAPTO structure. Background Art

[0002] Cutting is a material removal and forming method in the metal workpiece forming process, and it still accounts for a large proportion in today's mechanical manufacturing. The cutting process is the process of interaction between the metal workpiece and the tool. The tool cuts off the excess part from the metal workpiece to be processed, and under the premise of controlling productivity and cost, the metal workpiece obtains geometric accuracy, dimensional accuracy and surface quality that meet the design and process requirements.

[0003] The CAPTO tool holder used in the prior art is an integrated structure with the rest of the tool. The CAPTO tool holder adopts a hollow short cone structure with a large surface, which makes the tool holder surface pressure low, not easy to deform, and has low wear, so the precision retention is good. However, the triangular cone hole is difficult to process and the processing cost is high. In actual use, 100% of the entire tool body is scrapped due to wear and tear. The groove reserved for placing the blade is worn out. The expensive tool holder is not damaged but still needs to be scrapped together, resulting in waste of parts and increased production costs.

[0004] In this regard, utility model patent CN 216632632U discloses a split CNC turning tool head, in which the tool head is horizontally inserted into the slot of the tool holder. The tool head is in the slot, and the lateral position of the tool head in the slot is determined by adjusting the limit bolt. After the lateral positioning is completed, the locking bolt on the upper end of the tool holder is further locked, and the tool head in the slot is pressed and fixed from top to bottom to complete the positioning in the slot. Through the split design, when the tool head is damaged, only the tool head part needs to be replaced, thereby retaining the tool holder part with higher precision, thereby effectively saving the cost of maintaining the tool. However, since the limit bolt only plays a unilateral limiting role on the tool head, although the locking bolt passes through the tool holder, the tool head is only fixed by pressing. When cutting metal workpieces, the tool rigidity is reduced and the tool vibration is serious, and the workpiece processing qualification rate cannot be guaranteed. Utility Model Content

[0005] The technical problem to be solved by the utility model is to ensure that the various parts of the tool body are firmly connected and the rigidity of the tool body is improved under the premise of realizing a split structure of the tool so that the tool handle can be reused. In view of the shortcomings of the existing technology, a split CAPTO structure is provided.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0007] A split CAPTO structure, characterized in that it includes a tool handle, a tool clamp, a fixing pin and a tool head; the tool handle and the tool clamp are connected by the fixing pin, one end of the fixing pin is plugged into the tool handle, and the other end is fixedly connected to the tool clamp, and the tool clamp is fixedly connected to the tool head.

[0008] Furthermore, there are a plurality of fixing pins between the tool handle and the tool holder.

[0009] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0010] Compared with the prior art, the utility model provides a split CAPTO structure, which introduces a tool clamp and uses a fixing pin to connect the tool clamp and the tool handle, thereby changing the originally integrated tool into a split structure, so that the tool handle can be recycled, saving a lot of cost. The insertion of multiple fixing pins not only replaces the bolts to limit the tool clamp, but also improves the tightness of the connection between the tool clamp and the tool handle, prevents the tool vibration phenomenon and thus causes irreversible damage to the tool and the metal workpiece to be processed, and has good practicality. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Among them, 1-tool handle, 2-tool clamp, 201-fixing pin, 3-tool head. DETAILED DESCRIPTION

[0013] In order to better understand the present invention, the content of the present invention is further clearly described below in conjunction with the embodiments, but the protection content of the present invention is not limited to the following embodiments. In the following description, a large number of specific details are given in order to provide a more thorough understanding of the present invention. However, it is obvious to those skilled in the art that the present invention can be implemented without one or more of these details.

[0014] In the present invention, unless otherwise clearly specified and limited, the terms such as "connection" shall be understood in a broad sense, for example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a direct connection, or an indirect connection through an intermediate medium, or it may be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0015] Example 1

[0016] See also Figure 1, including a tool handle 1, a tool clamp 2, a fixing pin 201 and a tool head 3; the tool handle 1 and the tool clamp 2 are connected by a plurality of fixing pins 201, one end of the fixing pin 201 is plugged into the tool handle 1, and the other end is fixedly connected to the tool clamp 2, and the tool clamp 2 is fixedly connected to the tool head 3.

[0017] The technical solution provided in the embodiment of the present application changes the original one-piece design of the tool into a split structure through a tool handle, a tool clamp and a fixing pin, so that the tool handle can be recycled, saving a lot of cost. The insertion of multiple fixing pins improves the tightness of the connection between the tool clamp and the tool handle while limiting the tool clamp, preventing the tool vibration caused by loose connection and causing irreversible damage to the tool and the metal workpiece to be processed. The technical solution has good practicality.

[0018] Finally, it should be noted that the above embodiments are only preferred embodiments of the present invention, which are only used to illustrate the technical solution of the present invention rather than to limit it. Any modification, improvement, other modification or equivalent replacement made to the technical solution of the present invention by ordinary technicians in this field, as long as they do not depart from the spirit and scope of the technical solution of the present invention, should be included in the protection scope of the present invention.
