[0035] Specifically, the bottom surface of the bending rack 271 is welded and fixed with a rotating shaft 272 rotatably connected to the top surface of the second sliding table 250, the shaft tooth 273 is fixedly connected to the outer wall of the rotating shaft 272 and engages with the toothed plate 260, the outer wall top end of the bending rack 271 is fixedly connected with a telescopic rod 274, and the inner movable rod of the telescopic rod 274 is provided with a tapered chamfer on one end and is fixedly connected with the limiting frame 275 after penetrating through the bending frame 278 on the other end.

[0038] Further, when different types of tool measurement are performed, the electric push rod 277 in the mover 270 of the replacement mechanism 200 is started, the limiting frame 275 and the gripper 280 inside the limiting frame 275 are synchronously moved to the left by the bending frame 278, when the end of the gripper 280 moves to the outside of the transition sleeve 150, the movable rod in the telescopic rod 274 moves to the maximum stroke, and the position of the limiting frame 275 is fixed, the tapered chamfer at the end of the movable rod in the telescopic rod 274 is used to ensure the stability of the fixed position of the limiting frame 275 after the interference fit with the fixed rod outside the telescopic rod 274, and the subsequent bending frame 278 can extrude the first spring 276 to continue to move transversely to one side of the limiting frame 275.

[0039] When the bending frame 271 as a whole moves with the second sliding table 250, the shaft teeth 273 on the outer wall of the bottom surface rotating shaft 272 will engage with the tooth plate 260 when moving to the end of the transverse moving rail 220, and the mover 270 as a whole is rotated by 180°, the edge slot 2750 and the through slot 2751 on the limiting frame 275 are used to provide a moving interval for the structure inside the gripper 280.

[0040] This setting realizes the functions of transverse propulsion, limiting and overall rotation of the clamping unit, realizes 180° turning through the engagement of the tooth plate 260 and the shaft teeth 273, and ensures accurate positioning and coherent action in the replacement process through the buffering of the first spring 276 and the limiting of the telescopic rod 274, thereby improving the controllability and reliability of the mechanism movement.

[0041] Please refer to Figures 10-13 In the embodiment, the gripper 280 includes a lifting frame 281 and a pair of convex rods 282 arranged on the outer wall of the lifting frame 281. After the bending frame 278 continues to move transversely, the convex rods 282 move in the bending groove 2780, and the lifting frame 281 drives the gripper 280 as a whole to move upward.

[0042] Specifically, the lifting frame 281 slides inside the limiting frame 275, the convex rods 282 are fixed and connected on the outer wall of the lifting frame 281 by bolts and extend to the inside of the bending groove 2780 through the edge slot 2750, the left side of the lifting frame 281 is provided with a contraction block 283, the two ends of the contraction block 283 are hinged with connecting rods 284, the ends of the connecting rods 284 are hinged with clamping rods 285, and the ends of the clamping rods 285 are hinged with convex blocks on the outer wall of the lifting frame 281.

[0043] Further, the holder 280 further comprises a lifting rod 286 sliding in the bent frame 278, a transition pipe 287 sleeved outside the lifting rod 286 and rotating in the lifting frame 281, a contraction pipe 288 sleeved outside the transition pipe 287 and having a center shaft end extending to the left side of the contraction block 283, and a second spring 289 sleeved outside the contraction pipe 288.

[0044] Further, the end of the lifting rod 286 is welded with a pair of protrusions 2860, the inner wall of the transition pipe 287 is provided with a pair of guide grooves 2870 and the outer wall is welded with a pushing block 2871, the inner wall of the contraction pipe 288 is provided with a helical groove 2880 matching the size of the pushing block 2871, and the two ends of the second spring 289 are respectively welded and fixed with the outer wall of the contraction block 283 and the inner wall of the center shaft end disc of the contraction pipe 288.

[0045] Further, the electric push rod 277 continues to push, and the bent frame 278 compresses the first spring 276 to continue to move right. At this time, the protruding rods 282 on both sides of the lifting frame 281 slide along the transverse section of the bent groove 2780, and the lifting rod 286 moves under the push of the bent frame 278, and the end protrusions 2860 move along the helical section of the guide groove 2870 in the transition pipe 287, driving the transition pipe 287 to rotate. The pushing block 2871 on the outer wall of the transition pipe 287 is embedded in the helical groove 2880 in the inner wall of the contraction pipe 288, driving the contraction pipe 288 to move axially towards the bent frame 278, compressing the second spring 289 with the center shaft end disc, and making the contraction block 283 contract inward, thereby adjusting the unfolding angle of the clamping rod 285 through the connecting rod 284 mechanism, and stably clamping the transition sleeve 150 on the main shaft 140.

[0046] Subsequently, the bent frame 278 continues to move, the protrusions 2860 at the end of the lifting rod 286 enter the straight section of the guide groove 2870, ensuring the stability of the angle of the transition pipe 287; at the same time, the protruding rods 282 ascend along the inclined section of the bent groove 2780, driving the lifting frame 281 and the entire holder 280 to move upwards, thereby taking out the transition sleeve 150 from the main shaft 140.

[0047] This arrangement realizes the lifting movement through the cooperation of the protruding rods 282 and the bent groove 2780, and converts the linear motion into the retracting and unfolding action of the clamping rod 285 through the transition pipe 287 and the contraction pipe 288, thereby reliably grabbing and releasing the transition sleeve 150, completing accurate taking and placing, and improving the automation degree of the sleeve changing process.

[0048] The programmable controlled high-precision machine tool setting tool outside the instrument of the present application is used as follows: first, the operator installs the measured tool in the transition sleeve 150 of the tool setting device 100, and starts the pneumatic clamp inside the main shaft 140 to stably clamp the tool.

[0049] Then, by controlling the first motor 160 inside the horizontal guide rail 110 and the vertical guide rail 120 respectively, the first lead screw 170 is driven to rotate, and the first sliding table 180 is accurately moved, so that the measuring instrument 130 is positioned along the predetermined path to the outside of the tool. The measuring instrument 130 measures the key size parameters such as the length and diameter of the tool with high precision. After the measurement is completed, the first motor 160 is controlled to make the measuring instrument 130 retreat to the safe position, the pneumatic clamp of the main shaft 140 is loosened, and the operator can take out the measured tool.

[0050] If the tool type needs to be replaced and the corresponding transition sleeve 150 is adapted, the sleeve changing mechanism 200 is started. The electric push rod 277 in the mover 270 is controlled to extend, the bent frame 278 is pushed to move outward, and the limiting frame 275 and the clamp 280 are synchronously moved outward. When the front end of the clamp 280 moves to the outside of the transition sleeve 150, the telescopic rod 274 reaches the maximum stroke, and the position of the limiting frame 275 is locked.

[0051] Subsequently, the electric push rod 277 continues to advance, the bent frame 278 compresses the first spring 276 and continues to move to the right. At this time, the convex rods 282 on both sides of the lifting frame 281 slide along the transverse section of the bent groove 2780, and the end convex block 2860 of the lifting rod 286 moves along the spiral section of the guide groove 2870 in the transition pipe 287 under the push of the bent frame 278, driving the transition pipe 287 to rotate. The knob 2871 on the outer wall of the transition pipe 287 is embedded in the spiral groove 2880 on the inner wall of the contraction pipe 288, driving the contraction pipe 288 to move axially to the bent frame 278, compressing the second spring 289 with the center shaft end plate, and making the contraction block 283 contract inward, thereby adjusting the unfolding angle of the clamping rod 285 through the connecting rod 284 mechanism, and stably clamping the transition sleeve 150 on the main shaft 140.

[0052] Subsequently, the bent frame 278 continues to move, the convex block 2860 at the end of the lifting rod 286 enters the straight section of the guide groove 2870, ensuring the stability of the angle of the transition pipe 287; at the same time, the convex rods 282 ascend along the inclined section of the bent groove 2780, driving the lifting frame 281 and the entire clamp 280 to move upward, thereby taking out the transition sleeve 150 from the main shaft 140.

[0053] After that, the second motor 230 on the support table 210 is started to drive the second lead screw 240 to rotate, adjusting the horizontal position of the second sliding table 250. During the movement, the shaft teeth 273 at the bottom of the bent frame 271 engage with the tooth plate 260, making the mover 270 rotate by 180° as a whole, and the clamped transition sleeve 150 is transported to the above of the corresponding position of the storage rack 290. The electric push rod 277 is controlled to retract, the bent frame 278 is reset, and the transition sleeve 150 is stably placed in the storage hole.

[0054] Finally, the second motor 230 is continuously controlled to drive the gripper 280 to move to the transition sleeve 150 of another specification, and the above-mentioned clamping and placing actions are repeated to load the new transition sleeve 150 into the spindle 140, so that the measurement operation of the next batch of tools can be performed, thereby realizing the quick and automatic transition sleeve 150 replacement and continuous measurement process.

[0055] The foregoing description of specific exemplary embodiments of the application has been presented for the purposes of illustration and description. It is not intended to be exhaustive or to limit the application to the precise forms disclosed, and obviously many modifications and variations are possible in light of the above teaching. It is intended that the scope of the application be limited not with reference to the specific exemplifying embodiments described above, but rather to the appended claims and their equivalents.
