DETAILED DESCRIPTION

[0023] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0024] The present invention provides a titanium ring surface treatment device, which aims to solve the problems of cumbersome clamping and low efficiency in polishing the inner and outer rings of titanium rings in the prior art. By optimizing the structure and function of the clamping mechanism and the polishing assembly, and combining it with an automatic control system, the device can efficiently and continuously complete the polishing operation of the inner and outer walls of the titanium ring while ensuring the surface treatment quality.

[0025] like Figure 1-5The titanium ring surface treatment device shown includes a base 1, and a rotating chuck 2 and a polishing assembly 3 are provided at the upper end of the base 1. The core components of the rotating chuck 2 are a frustum base 21 and a disc 22. The frustum base 21 is driven to rotate by a servo 5 installed at its bottom. The servo 5 drives the disc 22 to rotate automatically, and synchronously drives the titanium ring clamped at its upper end to rotate. In conjunction with the polishing assembly 3, the titanium ring can be fully polished. The top of the conical base 21 is open and has a accommodating cavity with an axial extension. The disc 22 is arranged at the opening of the conical base 21. Four straight grooves 221 extending along the radial direction are opened circumferentially on the disc 22. The straight grooves 221 pass through the upper and lower surfaces of the disc 22, and a slider 23 is slidably arranged in each straight groove 221. Two blocks 24 are respectively provided on the upper side of the slider 23, and the two blocks 24 are arranged opposite to each other. Among them, the block 24 close to the center of the disc 22 is used to clamp the inner wall of the titanium ring, and the block 24 away from the center of the disc 22 is used to clamp the outer wall of the titanium ring.

[0026] When clamping the titanium ring, the inner and outer clamping blocks 24 on the four sliders 23 act on the titanium ring synchronously, expanding outward or converging inward to achieve the clamping function. This is achieved by the square plate 25, the L-shaped crank arm 26, and the first telescopic mechanism 27. Specifically, a square plate 25 is coaxially arranged at the bottom of the disc 22. The square plate 25 is rotatably connected to the disc 22 or the frustum base 21. The bottom of each slider 23 is hinged to the four corners of the square plate 25 via an L-shaped crank arm 26. When the square plate 25 is rotated, the L-shaped crank arm 26 can synchronously drive the four sliders 23 to slide along the straight groove 221. The first telescopic mechanism 27 serves as a driving device and is disposed in the accommodating cavity of the base 21. The two opposing sliders 23 are connected by the first telescopic mechanism 27. Specifically, the first telescopic mechanism 27 uses an oil cylinder. The rear end of the oil cylinder housing is hinged to one of the sliders 23 via a pin, and the front end of the telescopic rod is hinged to the other slider 23 at the opposite position via a pin. When the oil cylinder is extended or retracted, it can drive the two sliders 23 in the relative positions to move closer or farther away, and the other two sliders will run synchronously through the transmission of the L-shaped arm 26 and the square plate 25. Furthermore, the above-mentioned oil cylinders are arranged in two parallel positions, and the bottom of the casing is connected to a slide assembly 4. The slide assembly 4 includes a slide rail 41 and a movable slide 42. The slide rail 41 is fixed in the accommodating cavity of the truncated cone base 21, and the movable slide 42 is installed at the bottom of the casing of the oil cylinder. The setting of the slide assembly 4 ensures that the oil cylinder can move smoothly along the set trajectory during operation, further ensuring the accuracy and reliability of the switching of the clamping mechanism.

[0027] During polishing, in order to reduce the interference of the non-working block 24 on the polishing wheel 34, the distance between the two blocks 24 needs to be increased, but the influence of the stroke of the slider 23 must also be considered. Figure 5As shown, in a specific embodiment, the upper end surface of the slider 23 is provided with two symmetrical sliding grooves 231. Each sliding groove 231 is provided with an inner limiting portion 232 and an outer limiting portion 233 at its two ends. Specifically, the ends of the two sliding grooves 231 that are close to each other are the inner limiting portion 232, and the ends that are separated from each other are the outer limiting portion 233. The sliding grooves 231 are provided with a sliding portion 234 that is slidably connected thereto. The sliding portion 234 is formed with a blocking portion near the inner limiting portion 232, and the overall structure is T-shaped. The sliding groove 231 with the inner and outer limiting portions 232, 233 is generally concave in shape. The inner and outer limiting portions 232, 233 serve to limit the sliding portion 234. The two sliding portions 234 are connected by a tension spring 235. The tension spring 235 serves to reset the sliding portion 234. The two blocking blocks 24 on the same slider 23 are respectively fixedly connected to one of the sliding portions 234.

[0028] This structural design enables a larger distance to be generated between the two clamping blocks 24 on the same slider 23 during the clamping process, thereby not interfering with the normal operation of the polishing wheel 34 .

[0029] refer to Figure 1 The polishing assembly 3 is arranged at the rear end of the base 1, and includes a lifting mechanism 31, a second telescopic mechanism 32, a motor 33 and a polishing wheel 34. The lifting mechanism 31 is arranged at the rear end of the base 1, the second telescopic mechanism 32 is arranged at the upper end of the lifting mechanism 31, the motor 33 is arranged at the front end of the second telescopic mechanism 32, and the polishing wheel 34 is arranged on the rotating shaft of the motor 33. In a specific embodiment, the lifting mechanism 31 and the second telescopic mechanism 32 can be a kind of electric cylinder or oil cylinder. The lifting mechanism 31 is responsible for adjusting the height of the polishing wheel 34 to adapt to titanium rings of different heights; the second telescopic mechanism 32 is used to control the horizontal feed of the polishing wheel 34 to ensure that the polishing wheel maintains an ideal contact state with the surface of the titanium ring; through the cooperation of the lifting mechanism 31 and the second telescopic mechanism 32, the polishing wheel 34 can quickly approach the inner ring or outer ring of the titanium ring. Furthermore, a vertical slide is also provided on the rear side of the second telescopic mechanism 32, and the movable end of the slide is connected to the second telescopic mechanism 32. By providing a vertical slide, the operation stability of the polishing assembly 3 can be improved.

[0030] In addition, the device is also equipped with an integrated controller 6, which is arranged on one side of the base 1. It is electrically connected to the lifting mechanism 31, the first telescopic mechanism 27, the second telescopic mechanism 32, the motor 33 and the servo 5 respectively. The controller 6 can realize automatic and intelligent control of the entire device.

[0031] During the actual operation, the titanium ring is first placed on the disc 22 and between the inner and outer blocks 24. The inner and outer diameters, height and other dimensions of the titanium ring are input into the integrated controller 6. Then the integrated controller 6 controls the first telescopic mechanism 27 to operate, and drives the slider 23 to move toward the inside of the disc 22 through the L-shaped arm 26 and the square plate 25. At this time, the outer end block 24 clamps the outer wall of the titanium ring, the inner end block is in a released state, and the titanium ring is concentric with the disc 22. Then the integrated controller 6 controls the lifting mechanism 31 and the second telescopic mechanism 32 to cooperate with each other to move the polishing wheel 34 to the inner wall of the titanium ring, and the polishing wheel 34 begins to polish the inner wall of the titanium ring. When the inner wall polishing is completed (rotated at least 360 degrees), the controller 6 sends a command, and the first telescopic mechanism 27 drives the slider 23 to move outward through the L-shaped arm 26 and the square plate 25, and switches to the inner end block 24 to clamp the inner wall of the titanium ring. At this time, the outer end block 24 is released, and the lifting mechanism 31 and the second telescopic mechanism 32 cooperate with each other to move the polishing wheel 34 to the outer wall of the titanium ring, and the polishing wheel 34 then polishes the outer wall of the titanium ring. The entire clamping and switching process does not require re-clamping the titanium ring, and is smooth and coherent, which greatly shortens the equipment downtime and improves the polishing efficiency. The use of this device can significantly improve the consistency and smoothness of the titanium ring surface quality, meeting the high-precision and high-efficiency requirements of modern manufacturing for titanium ring surface treatment.
