Description

Technical Field

[0001] This utility model relates to the field of tool calibration technology, specifically a tool calibration device for supporting shaft machining. Background Technology

[0002] A shaft is a cylindrical object that passes through the center of a bearing, wheel, or gear, although some are square. A shaft is a mechanical part that supports rotating parts and rotates with them to transmit motion, torque, or bending moment. It is generally a round metal rod, and different sections can have different diameters. Rotating parts in a machine are mounted on shafts.

[0003] In the machining of support shafts, positioning grooves are cut into the support shaft by the tool to ensure the precise assembly and positioning of parts. However, due to the precision errors of the tool, tool holder, and collet, they are assembled together and mounted on the machine tool spindle. During machining, assembly precision errors will occur, which will cause the product machining precision to be unreliable. These errors will then deviate from the ideal machining path precision during the tool cutting process, ultimately leading to out-of-tolerance phenomena in the dimensions of the machined product.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-4 This utility model discloses a tool correction device for supporting shaft machining, including a frame 1. A machine tool spindle 2 driven by a geared motor is mounted on the frame 1. A three-jaw chuck 3 is installed at the end of the machine tool spindle 2. The three-jaw chuck 3 holds a cutting tool 4. A fixed plate 5 is mounted on the frame 1 above the cutting tool 4. A horizontal slide plate 7 is provided on the fixed plate 5. A first belt displacement mechanism 6 is installed on the fixed plate 5 to drive the horizontal slide plate 7 to move along the Y-axis. A vertical plate 8 is installed on the top of the horizontal slide plate 7. A liftable lifting plate 10 is driven by a second belt displacement mechanism 9 on the vertical plate 8. A non-contact vision inspection device is installed on the lifting plate 10.

[0019] Specifically, the non-contact visual inspection device includes a CCD camera 11, a telecentric lens 12, and a coaxial light source 13. The CCD camera 11, the telecentric lens 12, and the coaxial light source 13 are coaxially mounted on the end of the lifting plate 10 and located above the cutting tool 4.

[0020] In this embodiment, the CCD camera 11, telecentric lens 12, and coaxial light source 13 work together to capture multi-angle images of the tool circumference. Then, the three-dimensional shape of the tool is reconstructed by image stitching technology to obtain accurate tool acquisition, so as to subsequently correct the cutting tool 4 fixed by the three-jaw chuck 3.

[0021] Specifically, the first belt displacement mechanism 6 includes a first synchronous pulley 14, a first synchronous belt 15, and a first motor 17. The top of the fixed plate 5 is rotatably connected to two first synchronous pulleys 14, and the two first synchronous pulleys 14 are connected by a first synchronous belt 15. The bottom of the fixed plate 5 is equipped with a first motor 17 that drives one of the first synchronous pulleys 14 to rotate. The first synchronous belt 15 is connected to the horizontal slide plate 7 to drive the horizontal slide plate 7 to move.

[0022] The top of the fixed plate 5 is equipped with a first linear guide rail 16, and the bottom of the horizontal slide plate 7 is fixedly connected with a first slider that slides in cooperation with the first linear guide rail 16.

[0023] In this embodiment, the first motor 17 drives one of the first synchronous pulleys 14 to rotate, thereby enabling the first synchronous belt 15 to move. This causes the horizontal slide plate 7 to slide along the first linear guide rail 16, thus moving in the Y-axis direction, so that the non-contact vision inspection device can adjust its position.

[0024] A Y-axis grating ruler that cooperates with the first linear guide rail 16 and the first slider can be installed on the fixed plate 5.

[0025] Specifically, the second belt displacement mechanism 9 includes a second synchronous pulley 18, a second synchronous belt 19, and a second motor 20. Two second synchronous pulleys 18 are rotatably connected to the front side of the upright plate 8. The two second synchronous pulleys 18 are connected by a second synchronous belt 19. A second motor 20 is installed on the rear side of the upright plate 8 to drive one of the second synchronous pulleys 18 to rotate. The second synchronous belt 19 drives the lifting plate 10 to rise and fall.

[0026] In this embodiment, the second motor 20 drives one of the second synchronous pulleys 18 to rotate, so that the second synchronous belt 19 can drive the lifting plate 10 to move vertically, so that the non-contact vision inspection device can adjust its position in the vertical direction.

[0027] A Z-axis grating ruler that cooperates with the second linear guide rail 22 and the second slider can be installed on the side plate 21.

[0028] In summary, this support shaft machining tool correction device uses a non-contact vision inspection device to inspect the cutting tool 4 fixed by the three-jaw chuck 3. It can capture multi-angle images of the cutting tool 4 in the circumferential direction and the parameter data of the moving cutting tool 4, so as to guide the correction of the cutting tool 4.
