Description

Technical Field

[0001] This utility model relates to the field of machine tool manufacturing technology, and more specifically, it relates to a composite tool disc for a tool turret. Background Technology

[0002] Some tools mounted on a composite cutter head can be used for drilling if they rotate at high speed and move axially simultaneously; and for milling if they rotate at high speed and move radially simultaneously. However, changing between these two states requires re-clamping the tools. The tools need to be removed from their original position on the side of the cutter head and installed on the end face, or vice versa. This process requires secondary positioning, is cumbersome and time-consuming, and results in poor overall performance. Therefore, this invention proposes a composite cutter head for a turret. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a composite cutterhead for turrets, which has a novel structure and an adjustable mounting surface.

[0004] To solve the above-mentioned technical problems, the purpose of this utility model is achieved as follows: The present utility model relates to a composite cutter head for a turret, comprising a cutter head body in the shape of a regular octagonal prism or a regular dodecagonal prism. Each side of the cutter head body is respectively provided with a radially deep mounting groove. The front side of the mounting groove communicates with the outside. Each mounting groove is provided with a shaft whose axis extends along the width direction of the mounting groove. A mounting block for switching positions within the mounting groove is rotatably connected to the shaft. The mounting block is provided with a tool mounting surface flush with the side or front face of the cutter head body. A tail plate is provided at the end of the mounting block facing away from the tool mounting surface. A threaded hole is provided on the tail plate. The bottom of the mounting groove is also provided with a clearance groove for the tail plate to move within it. A first screw through hole matching the threaded hole is provided on the front face of the cutter head body. A second screw through hole matching the threaded hole is provided on the side of the cutter head body. It also includes a locking screw inserted into the first screw through hole or the second screw through hole.

[0005] When the mounting block is rotated to the point where the tool mounting surface is flush with the side, the locking screw is inserted into the first screw hole and threaded into the threaded hole.

[0006] When the mounting block is rotated until the tool mounting surface is flush with the front end surface, the locking screw is inserted into the second screw hole and threaded into the threaded hole.

[0007] The present invention is further configured such that: when the mounting block is rotated to the point where the tool mounting surface is flush with the side surface, one side of the mounting block rests against the side wall of the mounting square groove; when the mounting block is rotated to the point where the tool mounting surface is flush with the front end surface, the other side of the mounting block rests against the bottom wall of the mounting square groove.

[0008] The present invention is further configured such that: both the first screw hole and the second screw hole are countersunk holes designed to completely bury the locking screw.

[0009] The present invention is further configured such that: a tool mounting hole is arranged on the tool mounting surface.

[0010] The present invention is further configured such that the tool mounting holes are arranged in a rectangular array or a ring array on the tool mounting surface.

[0011] In summary, the present invention has the following beneficial effects: the composite cutter disc for turrets involved in the present invention can directly adjust the cutter mounted on it by changing the position of the mounting block, without the need for secondary disassembly and assembly of the cutter, making the operation flexible and convenient, with complete overall functions and strong practicality.

However, it should be understood that these descriptions are only for further illustrating the features and advantages of this utility model, and not for limiting the patent claims of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.

[0018] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0019] Example 1

[0020] See Figures 1 to 5 As shown, the composite cutterhead for a turret involved in this embodiment includes a cutterhead body 1 in the shape of a regular octagonal prism. Each side of the cutterhead body 1 is provided with a radially deep mounting groove 2. The front side of the mounting groove 2 communicates with the outside. Each mounting groove 2 is provided with a shaft 3 whose axis extends along the width of the mounting groove. A mounting block 4 that can switch positions in the mounting groove is rotatably connected to the shaft 3. The mounting block 4 is provided with a tool mounting surface 5 that is flush with the side or front face of the cutterhead body 1. The end of the mounting block 4 facing away from the tool mounting surface is provided with a tail plate 6. The tail plate 6 is provided with a threaded hole 7. The bottom of the mounting groove 2 is also provided with a clearance groove 8 for the tail plate to move inside. The front face of the cutterhead body 1 is provided with a first screw through hole 9 that matches the threaded hole. The side of the cutterhead body 1 is provided with a second screw through hole 10 that matches the threaded hole. It also includes a locking screw 11 that passes through the first screw through hole 9 or the second screw through hole 10.

[0021] When the mounting block 4 is rotated to the point where the tool mounting surface 5 is flush with the side, the locking screw 11 is inserted into the first screw hole 9 and threaded into the threaded hole 7.

[0022] When the mounting block 4 is rotated until the tool mounting surface 5 is flush with the front end surface, the locking screw 11 is inserted into the second screw hole 10 and threaded into the threaded hole 7.

[0023] Furthermore, when the mounting block 4 is rotated to the point where the tool mounting surface 5 is flush with the side surface, one side of the mounting block 4 rests against the side wall of the mounting square groove 2; when the mounting block 4 is rotated to the point where the tool mounting surface 5 is flush with the front end surface, the other side of the mounting block 4 rests against the bottom wall of the mounting square groove 2.

[0024] Furthermore, the tool mounting surface 5 is provided with tool mounting holes 12, which are arranged in a rectangular array or a ring array on the tool mounting surface 5.

[0025] In this implementation scheme, firstly, at the cutter head, as... Figure 2 In the indicated state, the tool is mounted on the tool mounting surface 5 on the side, and the locking screw 11 is inserted into the first screw hole 9 and threaded into the threaded hole 7. To change the tool position, the locking screw 11 can be unscrewed, and the mounting block 4 can be rotated circumferentially to rotate the tool by 90° until the tool mounting surface 5 is flush with the front end face of the tool disc. Then, the locking screw 11 is screwed back on, inserted into the second screw hole 10 and threaded into the threaded hole 7 (as shown). Figure 3 (As shown).

[0026] Example 2

[0028] In this embodiment, by setting the first screw hole 9 and the second screw hole 10 as countersunk holes, it is convenient to embed the locking screw during installation, and the rotating part of the locking screw is prevented from protruding from the side or end face of the cutter head, thus preventing interference with external mounting parts.

[0029] The composite cutter head for turrets involved in this utility model can directly adjust the cutter mounted on it by changing the position of the mounting block, without the need for secondary disassembly and assembly of the cutter. It is flexible and convenient to operate, has complete overall functions, and is highly practical.
