[0002] During the processing of cemented carbide bars, milling cutters are usually used for cutting. In order to ensure the normal use of the milling cutter, a cemented carbide bar processing edge detection fixture is set up to fix the position of the tool in order to accurately measure and evaluate the performance of the edge.

[0003] After searching, the Chinese patent application number 202220224983.7 discloses a fixing device for milling cutter detection, including a base plate, a mounting plate is provided above the base plate, a clamping mechanism for clamping the tool is provided on the top of the mounting plate, a rotating shaft is provided at the bottom of the mounting plate, a plane bearing is provided between the bottom of the mounting plate and the top of the base plate, and the plane bearing is sleeved on the rotating shaft. The utility model is convenient for rotating the milling cutter according to the detection needs, and does not require secondary clamping, which is more convenient to use and has higher detection efficiency;

[0004] The above patent still has the following shortcomings: (1) It is not convenient to fix the tool. The existing device uses a screw to drive two sets of clamps to move and fix the position of the tool during use. The process of rotating the screw takes a long time, which reduces work efficiency;

[0005] (2) It is not convenient to adjust the placement height, which makes it difficult to accurately position the blade edge to the preset detection position, which can easily cause measurement errors and affect the accurate evaluation of the blade edge performance.

[0006] Therefore, there is an urgent need for a cemented carbide bar machining cutting edge detection and fixing device to solve the above problems. Utility Model Content

[0007] The purpose of the utility model is to solve the problem that it is inconvenient to fix the tool at present. The existing device uses a screw rod to drive two sets of clamping jaws to move and fix the position of the tool during use. The process of rotating the screw rod takes a long time, which reduces the working efficiency.

[0008] In order to achieve the above-mentioned invention object, the utility model provides the following technical solutions:

[0019] Through the above technical solution, the second bevel gear drives the screw to rotate through the first bevel gear by twisting the knob, so that the screw sleeve drives the inner tube to slide inside the outer tube to adjust the height of the device.

[0020] As a preferred technical solution of the present application, the cross-sections of the outer tube and the inner tube in a plan view are elliptical structures, and a sliding structure is formed between the outer tube and the inner tube.

[0021] Through the above technical solution, the movement path of the inner tube is limited by sliding, thereby preventing the inner tube from rotating.

[0023] Through the above technical solution, it is convenient to drive the second bevel gear to rotate by twisting the knob, so that the second bevel gear drives the screw to rotate through the first bevel gear.

[0024] Compared with the prior art, the utility model has the following beneficial effects:

[0025] In the scheme of this application:

[0026] The pressing wheel is driven to rotate by pulling the push handle, so that the pressing wheel pushes the second clamping jaw to move toward the fixed structure, clamps the position of the fixed tool, and rotates the connecting rod to adjust the distance between the first clamping jaw and the second clamping jaw, thereby realizing the convenient fixing function of the device, facilitating the simple and rapid fixing of the position of the tool, improving work efficiency, reducing the time consumed by only fixing the tool, and enhancing the convenience of the device;

[0027] By twisting the knob, the second bevel gear drives the screw to rotate through the first bevel gear, so that the screw sleeve drives the inner tube to slide inside the outer tube and adjusts the height of the device.
