[0027] In order to facilitate understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. Embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.
[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.
[0029] Combination Figure 1-6 As shown, a device for grinding inner and outer walls of a cylindrical part comprises:
[0030] The equipment body 1 is horizontally arranged on a workbench, and a slide groove 13 is provided on the top surface, and guide rings 11 are arranged at both ends of the slide groove 13;
[0031] The grinding mechanism 2 is provided with two groups, the outer wall grinding structure is provided as an outer grinding ring 21, and the inner diameter is larger than the outer surface of the pipe, and the inner wall grinding structure is provided as an inner grinding disc 22, and the outer diameter is smaller than the inner diameter of the pipe, wherein the inner grinding disc 22 is arranged on one side of the equipment body 1, and the outer grinding ring 21 is arranged between the two guide rings 11;
[0032] The adjustment assembly 3 is arranged inside the guide ring 11 , the outer grinding ring 21 and the inner grinding disc 22 .
[0033] Specifically; in the present embodiment, the outer wall grinding structure and the inner wall grinding structure should both adopt adjustable structures to improve applicability, so the adjustment component 3 should be configured as a chuck clamping structure, that is, an adjustment disk 31 movably mounted inside the guide ring 11, the outer grinding ring 21 or the inner grinding disk 22, and the surface of the adjustment disk 31 is provided with a spiral groove. Since the guide ring 11 and the outer grinding ring 21 are both configured as annular, the adjustment disk 31 inside the guide ring 11 and the outer grinding ring 21 should also be configured as an annular structure.
[0034] In addition, rectangular slots are provided on the surfaces of the guide ring 11, the outer grinding ring 21 and the inner grinding disk 22, and a connecting seat 23 is movably installed inside the rectangular slots. The bottom of the connecting seat 23 passes through the rectangular slots and is partially movably inserted into the groove. Therefore, when the driving adjustment disk 31 is rotated, the connecting seat 23 can be expanded or contracted, thereby cooperating with the above-mentioned guide ring 11, outer grinding ring 21 and inner grinding disk 22 and other structures to contact the inner and outer walls of the pipe.
[0035] In the above structure, the guide ring 11 is a structure for fixing the pipe, so a conveying roller 12 can be set at the bottom of its connecting seat 23. Several conveying rollers 12 form a circular ring structure, so that after the guide ring 11 is initially fixed, the pipe can continue to be conveyed inward, thereby completing the initial positioning, so that the two ends of the entire pipe can be respectively clamped inside the two guide rings 11.
[0036] The outer grinding ring 21 and the inner grinding disc 22 are grinding structures, which need to be rotated to utilize the grinding head provided on the connecting seat 23 to rub against the inner and outer walls of the pipe. Therefore, a fixed bracket should be provided on the outer side wall of the outer grinding ring 21, and the fixed bracket is movably assembled with the outer grinding ring 21 using a ball bearing structure. At the same time, a gear block is also arranged around the side wall of the outer grinding ring 21, and a servo motor 25 is provided on one side of the fixed bracket. The output end of the servo motor 25 should extend to the inside of the fixed bracket and a gear sleeve should be provided at the end. The gear sleeve and the gear block are meshed with each other, thereby driving the outer grinding ring 21 to rotate rapidly inside the fixed bracket through gear transmission.
[0037] The inner grinding disc 22 needs to extend into the interior of the pipe, so the structure needs to have an electric push rod 24 on the back, and a riveted sleeve is provided at the end of the electric push rod 24, a drive motor 26 is embedded in the riveted sleeve, and the output end of the drive motor 26 is fixedly connected to the center of the back of the inner grinding disc 22, and the edge of the inner grinding disc 22 is fixedly connected to the end face of the riveted sleeve through a bearing structure. Therefore, when the internal drive motor 26 rotates, it can also synchronously achieve horizontal displacement through the electric push rod 24, thereby completing the inner wall grinding processing of the pipe.
[0038] During the grinding process, high-frequency friction will inevitably cause the pipe to vibrate. In order to prevent the vibration from being transmitted to the above-mentioned fixing structure and causing the chuck to reverse, in this embodiment, a worm 33 should be correspondingly arranged inside the guide ring 11, the outer grinding ring 21 and the inner grinding disc 22. The two ends of the worm 33 are rotatably connected to the inner wall of the grinding wheel respectively, and one end extends to the outside and is provided with an adjustment cap. At the same time, a worm wheel 32 is provided on the back of the chuck, and the worm 33 is meshed with the worm wheel 32. Therefore, the chuck can be adjusted by twisting the worm 33. After the fixation is completed, the worm wheel 32 and the worm 33 have a self-locking effect, which can prevent the loosening of the clamping structure due to factors such as vibration.
[0039] A screw is also provided inside the slide groove 13 located below the outer wall grinding mechanism 2, and the fixed bracket portion extends into the slide groove 13 and is penetrated by the screw. At the same time, an electric motor 14 is also provided on the outer wall of the equipment body 1. The output end of the electric motor 14 is transmission-connected to the end of the screw, thereby driving the outer grinding ring 21 to move horizontally.
[0040] In the above structure, an improvement is made based on the three-jaw chuck structure, that is, the spiral arc groove wall is used to force the connecting seat 23 to gather toward the center or expand outward, so as to fix the pipe and adjust the grinding mechanism 2, thereby achieving the purpose of adjustability. It can be effectively applied to pipes of various specifications, greatly improving the convenience of processing and use.
[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solution recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solution from the technical solution of the embodiments of the utility model.
