Description

A cutting holder for slicing ultra-thick parts Technical Field

[0001] This utility model relates to the field of parts cutting technology, specifically a cutting tool holder for cutting ultra-thick parts. Background Technology

[0002] In the production of forgings of various sizes, in order to save costs and improve efficiency, forgings are often made into multiple parts and then cut together. In conventional cutting processes, the working length of the cutting tool is relatively short (generally ≤30mm), and the ordinary extended cutting tool is ≤65mm. However, our company encounters the problem of cutting ultra-thick parts, and some of the parts that need to be cut are even 350mm or thicker. Therefore, a special extended cutting tool device is required.

[0003] Existing cutting tool holders typically rely on pre-tensioning of the holder's own structure to quickly adjust the length of extra-long cutting tools. Usually, when clamping the tool in a cutting tool holder with extended cutting tools, it is secured with bolts using a flat pressure block. However, this setup often has the following drawbacks: 1. Because the tool is a flat block, and the extended tool is also heavier, it cannot be accurately positioned, hindering rapid clamping; 2. During machining, the tool is prone to slipping out under pressure due to the lack of a limiting mechanism, affecting safety. Summary of the Invention

[0004] The purpose of this invention is to overcome the aforementioned technical difficulties and provide a cutting tool holder that can be quickly pre-tightened and positioned for clamping, and can prevent the cutting tool from flipping and sliding out for cutting ultra-thick parts.

[0005] To achieve the above objectives, the technical solution adopted is as follows: a cutting tool holder for cutting ultra-thick parts, comprising a tool holder body and a cutting tool, wherein a groove for placing the cutting tool is provided on one side of the tool holder body, and baffles parallel to the bottom surface of the groove are provided at both the upper and lower ends of the groove, and a self-pre-tightening mechanism is provided on the side of the tool holder body near the baffles;

[0006] The self-pre-tightening mechanism is a sandwich structure formed by the connection between the bottom and side surfaces of the groove on the tool holder body;

[0007] The tool holder body is provided with a locking mechanism below its own pre-tightening mechanism. The locking mechanism includes multiple threaded through holes that penetrate the outer wall of the tool holder body below the interlayer. The tool holder body is provided with multiple countersunk holes that correspond to the size and position of the threaded through holes above the interlayer. A locking bolt is provided in the threaded through hole that passes through the threaded through hole and the interlayer and is threadedly connected to the countersunk hole.

[0008] Furthermore, the tool holder body has a cylindrical through hole at one end of the interlayer away from the groove, which is connected to the interlayer.

[0009] Furthermore, the angle between the interlayer and the bottom surface of the groove is 100-110°.

[0010] Furthermore, the height of the baffle is 0.2-1cm, and the thickness of the baffle is 0.1-0.3cm.

[0011] Furthermore, the cutter includes a cutter body and cutter blades. The two ends of the cutter body are placed in the groove and the inner wall of the baffle, and the cutter blades are respectively located at the four apex corners of the two ends of the cutter body.

[0012] Furthermore, the threaded through holes are provided in 4-7 portions.

[0013] Furthermore, the outer wall of the countersunk hole is positioned close to the bottom surface of the groove.

[0014] The beneficial effects of adopting the above solution are as follows: When using this cutter holder for cutting ultra-thick parts, the cutter is placed in the groove, and the locking bolt is passed through the threaded through hole and the interlayer and then connected to the countersunk hole thread. At this time, the outer wall of the cutter is clamped by the baffle and the inner wall of the groove. Tightening the locking bolt can narrow the gap of the interlayer, so that the cutter is better locked in the groove. The whole system achieves rapid pre-tightening positioning and clamping. At the same time, it prevents the cutter from flipping and slipping out during cutting, avoiding the blade from cutting off-center and causing safety accidents, resulting in product scrap.

[0020] The technical solution of this utility model will be clearly and completely described below with reference to specific embodiments. The described embodiments are merely some, not all, of these embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0021] Example 1

[0022] As shown in Figures 1-4, a cutting tool holder for cutting ultra-thick parts includes a tool holder body 1 and a cutting tool. A groove 2 for placing the cutting tool is provided on one side of the tool holder body 1. Both the upper and lower ends of the groove 2 are provided with baffles 3 parallel to the bottom surface of the groove 2. The tool holder body 1 is provided with a self-pre-tightening mechanism on the side near the baffles 3.

[0023] The self-pre-tightening mechanism is a sandwich 7 opened in the tool holder body 1 at the angle between the bottom surface and the side surface of the groove 2;

[0024] The tool holder body 1 is provided with a locking mechanism below its own pre-tightening mechanism. The locking mechanism includes multiple threaded through holes 6 that are opened through the outer wall of the tool holder body 1 below the interlayer 7. The tool holder body 1 is provided with multiple countersunk holes 4 that correspond to the position and size of the threaded through holes 6 above the interlayer 7. Locking bolts 5 are provided in the threaded through holes 6, which pass through the threaded through holes 6 and the interlayer 7 and are threadedly connected to the countersunk holes 4.

[0025] In specific implementation, the tool holder body 1 has a cylindrical through hole 8 extending through the interlayer 7 at the end of the interlayer 7 away from the groove 2. This setting allows the interlayer 7 to have a better rebound effect. When the locking bolt 5 is tightened, the cylindrical through hole 8 acts as a buffer, allowing its own pre-tightening mechanism to rely on the elasticity of the material to lock, and to rebound and recover according to the elastic pressure.

[0026] The specific implementation method is as follows: When using this cutter holder for cutting ultra-thick parts, the cutter is placed in the groove 2, and the locking bolt 5 is threaded through the threaded through hole 6 and the interlayer 7 and then threaded into the countersunk hole 4. At this time, the outer wall of the cutter is clamped by the baffle 3 and the inner wall of the groove 2. Tightening the locking bolt 5 can narrow the gap of the interlayer 7, so that the cutter is better locked in the groove 2. The whole system achieves rapid pre-tightening positioning and clamping. At the same time, after application, it prevents the cutter from flipping and slipping out during cutting, causing safety accidents and resulting in product scrapping.

[0027] Example 2

[0028] Based on Embodiment 1, the angle between the interlayer 7 and the bottom surface of the groove 2 is 100-110°. This setting ensures that the interlayer 7 is neither too narrow nor too wide, thus preventing it from affecting the locking effect.

[0029] In specific implementation, the height of the baffle 3 is 0.2-1cm, and the thickness of the baffle 3 is 0.1-0.3cm.

[0030] In specific implementation, the cutter includes a cutter body 9 and cutter blades 10. The two ends of the cutter body 9 are placed within the groove 2 and the inner wall of the baffle 3. The cutter blades 10 are respectively located at the four apex corners of both ends of the cutter body 9. The cutter blades 10 can be connected to the cutter body 9 via a threaded connection.

[0031] Furthermore, the threaded through hole 6 is provided with 4-7 holes.

[0032] Furthermore, the outer wall of the countersunk hole 4 is positioned close to the bottom surface of the groove 2. This arrangement allows the interlayer 7 to be more stable during the tightening process. If the countersunk hole 4 is located far from the bottom surface of the groove 2, the clamping effect of the blade will be reduced.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.

[0034] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
