DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example 1

[0026] A fixture for a CNC quenching machine tool, such as Figure 1-Figure 4 As shown, it includes a support seat 1; an adjustment mechanism 2 is provided at the top of the support seat 1, and the adjustment mechanism 2 includes a fixed seat 201, which is fixedly connected to the top of the support seat 1, and the fixed seat 201 is an arc-shaped structure. The top of the fixed seat 201 is rotatably connected to a clamping base 202, and one side of the top of the fixed seat 201 is hinged with a positioning seat 203, and the top of the positioning seat 203 is connected to a positioning bolt 204, and the end of the positioning bolt 204 is rotatably connected to a clamping block 205. The adjustment mechanism 2 can be rotated and adjusted for the workpiece to be quenched, so as to facilitate the quenching of the workpiece at different angles. The fixing seat 201 can support the rotating assembly so that the clamping base 202 can rotate inside the fixing seat 201 and drive the workpiece inside the clamping base 202 to rotate synchronously. The positioning seat 203 structure can limit the top of the workpiece. At the same time, the positioning bolt 204 clamps and fixes the workpiece through the clamping block 205 at the end. The clamping block 205 is rotatably connected to the positioning bolt 204. Therefore, when the clamping block 205 tightens the workpiece, it does not affect the normal rotation of the workpiece. The top of the clamping block 205 is fixedly connected with a positioning rod 206 The top of the positioning rod 206 passes through the positioning bolt 204 and is arranged inside the positioning bolt 204. The end of the positioning rod 206 is fixedly connected with a return spring 207. The positioning rod 206 structure can position the clamping block 205 so that the clamping block 205 is kept at the end of the positioning bolt 204 for rotation. At the same time, the return spring 207 structure buffers the clamping block 205 and the positioning bolt 204 to avoid excessive clamping force causing the clamping block 205 to be blocked from rotating. The bottom end of the clamping base 202 is fixedly connected with a support rod 208, which passes through the fixed seat 201 is arranged inside the fixed seat 201, and a driving motor 209 is fixedly connected inside the support seat 1. The output shaft of the driving motor 209 passes through the support seat 1 and the fixed seat 201. The end of the output shaft of the driving motor 209 is fixedly connected to the support rod 208. The support rod 208 can support the clamping base 202, so that the clamping base 202 can be rotated and adjusted through the support rod 208. At the same time, the driving motor 209 structure can drive the support rod 208 and the clamping base 202, so that the clamping base 202 can drive the workpiece to rotate continuously.

[0027] Example 2

[0028] like Figure 1-4As shown in the figure, a clamping mechanism 3 is connected inside the clamping base 202. The clamping mechanism 3 includes fastening bolts 301, which are symmetrically arranged at the top ends on both sides of the clamping base 202. The end of the fastening bolt 301 is movably connected to a driving block 302. The driving block 302 has a "C" - shaped structure, and the structure of the driving block 302 corresponds to the structure of the end of the fastening bolt 301. The structure of the fastening bolt 301 can clamp and fix the workpiece, improving the stability of the workpiece. The fastening bolts 301 are symmetrically arranged on both sides of the clamping base 202 and form a central - symmetric structure with the positioning bolts 204, improving the clamping and fixing effect on the workpiece. The structure of the driving block 302 can drive the fastening bolt 301, so that when the fastening bolt 301 is inside the fixed seat 201, the driving block 302 can drive the fastening bolt 301. A driving rod 303 is fixedly connected to the outside of the driving block 302. The driving rod 303 passes through the fixed seat 201, and the driving rod 303 is slidably connected to the fixed seat 201. A buffer spring 304 is sleeved on the outside of the driving rod 303. The buffer spring 304 is arranged between the driving block 302 and the fixed seat 201. The structure of the driving rod 303 can drive and control the driving block 302, so that the driving block 302 slides along the direction of the driving rod 303, so that the driving block 302 cooperates with or separates from the fastening bolt 301. The structure of the buffer spring 304 can make the driving block 302 move away from the fastening bolt 301, thus preventing the driving block 302 from blocking the normal rotation of the clamping base 202. A buckle 305 is hinged to the side of the positioning seat 203. Torsion springs 306 are fixedly connected to both sides of the buckle 305. A clamping groove 307 is formed on the side of the fixed seat 201. The structures of the buckle 305 and the clamping groove 307 correspond to each other. The buckle 305 has a hook - shaped structure. The structure of the buckle 305 can fix the positioning seat 203 and the fixed seat 201 to each other, improving the clamping stability of the workpiece. The bottom end of the support seat 1 is slidably connected to a clamping plate 4. An installation bolt 5 is connected to the bottom end of the clamping plate 4. The top end of the installation bolt 5 passes through the support seat 1. The structure of the clamping plate 4 can cooperate with the support seat 1 and clamp and fix the device on the numerical control machine tool.

[0029] When the fixing device for a CNC quenching machine tool of the present invention is used, the workpiece to be quenched is placed on the inner side of the clamping base 202. After the positioning seat 203 is closed, the buckle 305 rotates inwards under the action of the torsion spring 306 and moves to the inside of the clamping groove 307. The buckle 305 and the clamping groove 307 cooperate with each other to fix the positioning seat 203 and the fixing seat 201 to each other. At the same time, the driving rod 303 is pressed inwards to make the driving block 302 move inwards and fit with the fastening bolt 301. At the same time, the driving rod 303 is rotated to make the fastening bolt 301 rotate inwards and the workpiece is fixed. The workpiece is clamped and fixed, and then the driving rod 303 is released. The driving rod 303 and the driving block 302 are away from the fastening bolt 301 under the elastic action of the buffer spring 304, and the positioning bolt 204 is rotated at the same time. The positioning bolt 204 clamps and fixes the workpiece through the clamping block 205 at the bottom and cooperates with the fastening bolt 301. Then the driving motor 209 is started, and the driving motor 209 drives the support rod 208 to rotate continuously. The clamping base 202 drives the workpiece to rotate synchronously under the transmission of the support rod 208. The continuously rotating workpiece can improve the quenching effect.
