Description
Technical Field
[0001] This utility model relates to the field of roundness meter chuck adjustment technology, and in particular to a roundness meter that facilitates adjustment of the chuck angle. Background Technology
[0002] As a precision measuring instrument, the cylindricity tester plays a crucial role in fields such as machinery manufacturing, automotive industry, and aerospace. It is primarily used to measure the cylindricity error of cylindrical workpieces, providing accurate data support for workpiece quality control. With the increasing demands for product precision in modern industry, more stringent requirements are being placed on the cylindricity tester's measurement accuracy, ease of operation, and adaptability.
[0003] Traditional cylindricity gauges require external tools to remove bolts when adjusting the angle of the chuck. This cumbersome operation not only prolongs the adjustment time but also easily leads to wear of the limit structure due to improper tool use, affecting the subsequent fixing effect. Furthermore, it is difficult to achieve precise angle control, which in turn affects the positioning accuracy of the workpiece and ultimately increases the measurement error. Utility Model Content

[0014] (III) Beneficial Effects
[0015] This utility model provides a cylindricity gauge that facilitates adjustment of the chuck angle, and has the following beneficial effects:
[0016] 1. This cylindricity gauge, which facilitates chuck angle adjustment, allows for chuck angle adjustment by rotating a limit pin on a screw rod. This releases the limit pin on the rotating plate. Rotating the rotating plate then moves a limit rod within a fixed plate. Once the plate reaches the desired position, rotating the limit pin again moves it to the screw rod, pressing it against the fixed plate and limiting the rotation. This achieves chuck angle adjustment, significantly improving the chuck's flexibility and stability during machining, making it suitable for high-precision workpiece clamping requirements.
[0017] 2. This cylindricity gauge, which facilitates chuck angle adjustment, uses a snap-fit assembly. During use, moving the sliding plate compresses the compression spring, allowing the insertion rod to be pulled out of the three-jaw chuck, releasing the chuck's limiting position. This enables the device to be replaced, preventing chuck wear over prolonged use, which can affect clamping accuracy and machining stability, leading to workpiece positioning deviations, increased machining errors, and even tool damage. This ensures the continuous and reliable operation of the entire machining system. Attached Figure Description

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.
[0024] Please see Figures 1 to 4This utility model provides a technical solution: a cylindricity gauge for easy adjustment of the chuck angle, comprising two sets of fixed plates 1, with an adjustment component 2 rotatably connected inside the two sets of fixed plates 1. The angle of the chuck is adjusted by adjusting the component 2. A mounting block 3 is fixedly connected to the top surface of the adjustment component 2, and a positioning plate 4 is fixedly connected to the top surface of the mounting block 3. A mounting plate 5 is rotatably connected inside the positioning plate 4. Two sets of snap-fit components 6 are provided inside the mounting plate 5, enabling quick installation and removal of the chuck. The adjusting assembly 2 includes a rotating plate 201 rotatably connected inside the two sets of fixed plates 1. Both ends of the rotating plate 201 are fixedly connected to limit rods 202. One side of each set of limit rods 202 is fixedly connected to a screw rod 203. The outer side of each set of screw rods 203 is threadedly connected to a limit pin 204. Both sets of snap-fit assemblies 6 include compression springs 601 disposed inside the mounting plate 5. One end of each set of compression springs 601 is fixedly connected to a sliding plate 602. One side of each set of sliding plates 602 is fixedly connected to a plug rod 603.
[0025] Mounting block 3 is fixedly connected to the top surface of rotating plate 201. A three-jaw chuck 17 is inserted into the interior of mounting plate 5. The three-jaw chuck 17 is used to fix the workpiece.
[0026] Both sides of the three-jaw chuck 17 are fixedly connected with locking blocks 7. Both sets of locking blocks 7 have insertion slots inside. The locking blocks 7 are used to install the three-jaw chuck 17.
[0027] The bottom surfaces of the two sets of fixing plates 1 are fixedly connected to the base plate 8, and the top surfaces of the base plate 8 are fixedly connected to the support frame 9. The support frame 9 serves to support the detection probe 16 and the like.
[0028] The support frame 9 has a threaded rod 10 inside, and a heat dissipation box 11 is fixedly connected to the top surface of the support frame 9. A servo motor is installed inside the heat dissipation box 11. The threaded rod 10 drives the moving block 12 to move up and down.
[0029] A movable block 12 is slidably connected to the outside of the support frame 9, and a connecting rod 13 is slidably connected inside the movable block 12. A support rod 14 is provided at one end of the connecting rod 13. The support rod 14 serves to support the detection probe 16.
[0030] A rotating block 15 is provided at one end of the support rod 14. A detection probe 16 is fixedly connected inside the rotating block 15. The detection probe 16 is used to detect the workpiece.
[0031] In this invention, the working steps of the device are as follows:
[0032] First step: When adjusting the angle of the chuck, rotate the limit pin 204. The limit pin 204 moves on the screw rod 203, releasing the limit on the rotating plate 201. Rotate the rotating plate 201. The rotation of the rotating plate 201 drives the limit rod 202 to move inside the fixed plate 1. After moving to the appropriate position, rotate the limit pin 204 again. The limit pin 204 moves on the screw rod 203 and presses against the fixed plate 1, limiting the rotating plate 201. This realizes the adjustment of the chuck angle, significantly improving the flexibility and stability of the chuck in the processing process, making it suitable for multi-angle, high-precision workpiece clamping requirements.
[0033] The second step: During use, the sliding plate 602 is moved, which compresses the compression spring 601. The insertion rod 603 is pulled out from inside the three-jaw chuck 17, releasing the limit on the three-jaw chuck 17. This allows the device to be replaced, preventing the chuck from wearing out over a long period of use, which would affect clamping accuracy and machining stability, and thus lead to problems such as workpiece positioning deviation, increased machining error, or even tool damage. This ensures the continuous and reliable operation of the entire machining system.
