Description

Technical Field

[0001] This utility model relates to the field of cutting technology, and in particular to a cutting tool for cutting. Background Technology

[0002] Machining is a machining method that uses cutting tools or grinding wheels to remove excess material from a workpiece. Through the relative movement of the tool and the workpiece, the cutting edge of the tool cuts into the workpiece surface, removing chips and thus obtaining parts with the desired geometry, dimensional accuracy, and surface quality. It is one of the most common and widely used metalworking processes in mechanical manufacturing, suitable for various production needs from roughing to finishing.

[0003] Because the machining process requires the use of multiple cutting tools to process the workpiece, the existing equipment requires disassembling multiple sets of bolts to release the fixing of the cutting tools and then fixing the replacement cutting tools with multiple sets of bolts, which leads to slow work progress and is very cumbersome. In addition, the cutting tools will wear out after a certain period of use and need to be replaced regularly. Therefore, a cutting tool for cutting is proposed to solve the above problems. Utility Model Content

[0006] The replacement mechanism includes a sliding sleeve that is slidably connected to the inner wall of the disc. A fixing ring is fixedly connected to the inner wall of the sliding sleeve. A cutting tool is slidably connected to the inner wall of the fixing ring. A bearing is fixedly connected to the outer wall of the cutting tool. The bearing is elastically connected to the bottom outer wall of the fixing ring by a first spring. A sliding block is fixedly connected to the outer wall of the sliding sleeve.

[0007] As a further description of the above technical solution: the disassembly mechanism includes a threaded rod, which is threadedly connected to the inner wall of the sliding sleeve. A guide block is fixedly connected to the inner wall of the threaded rod. A fixing rod is slidably connected to the inner wall of the disc. The fixing rod is elastically connected to the inner wall of the disc by a second spring. A fixing block is fixedly connected to the outer wall of the right end of the threaded rod.

[0008] As a further description of the above technical solution: the inner wall of the disk is provided with a number of sliding sleeves, and the number of sliding sleeves are arranged in a ring array on the inner wall of the disk.

[0009] As a further description of the above technical solution: the inner wall of the disk is provided with a sliding groove, and the sliding block is slidably connected to the inner wall of the sliding groove.

[0010] As a further description of the above technical solution: the top inner wall of the tool is provided with a bolt groove, the tool is slidably connected to the inner wall of the sliding sleeve, and the tool is inserted into the outer wall of the output shaft of the rotating shaft.

[0011] As a further description of the above technical solution: the outer ring of the bearing is provided with a connecting plate.

[0012] As a further description of the above technical solution: one end of the first spring is fixedly connected to the bottom outer wall of the fixed ring, and the other end of the first spring is fixedly connected to the top outer ring connecting plate of the bearing.

[0013] As a further description of the above technical solution: the inner wall of the threaded rod is provided with a groove, and the fixing rod is engaged in the groove.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, the tool is removed by pulling down the bolt to release the existing tool fixation, and the threaded rod is pulled back to restore the original position. Since multiple sets of sliding sleeves are distributed in a ring array on the inner wall of the disc, and each set of sliding sleeves is equipped with different types of tools on its inner wall, the required tool is moved to the bottom of the rotating shaft by sliding the sliding sleeve along the groove. The tool is then pulled down to insert into the output shaft of the rotating shaft and fixed by bolts, thus completing the replacement of different types of tools. This improves the problem of cumbersome and troublesome replacement of different types of tools in the prior art.

[0016] 2. In this utility model, rotating the threaded rod disengages it from the sliding sleeve, and then sliding the sliding sleeve until it disengages from the groove to disengage from the disc, allowing the tool to be replaced, thereby improving the problem of the need for regular tool replacement in the prior art.
