Description

Technical Field

[0001] The present invention relates to the technical field of grinding devices, and in particular to a multifunctional nuclear power metal bar end face grinding device. Background Art

[0002] In the field of nuclear power, metal bars are key structural and functional materials, and their processing accuracy and surface quality are directly related to the safety and stability of nuclear power plant operation. During the production and manufacturing process of metal bars, affected by cutting, forging and other processing techniques, the two end faces of the bars usually have defects such as uneven end faces, residual edge burrs and oxide layer adhesion. These defects will not only reduce the appearance quality of the metal bars, but may also bring serious safety hazards during subsequent assembly and use. Specifically, the uneven end faces will make it difficult to achieve a tight fit between the bars during connection, thereby affecting the mechanical properties and stability of the overall structure; and the presence of burrs and oxide layers will weaken the corrosion resistance of the bars and shorten the actual service life of nuclear power plant equipment. Therefore, before the metal bars are put into use, they need to be polished with the help of intelligent polishing devices.

[0003] At present, the existing metal bar end face grinding devices on the market still have many technical defects in practical applications: First, existing grinding devices generally use a single-shot, single-group processing mode. After each group of metal bars is ground, they must undergo a series of operations, including loosening, unloading, reloading, and fixing. These auxiliary processes consume a lot of time and cost, significantly extending the overall processing cycle, making it difficult to improve production efficiency and unable to meet the needs of large-scale production. Secondly, the existing grinding devices have relatively simple functions. After completing the grinding operation, they usually need to be equipped with expensive detection equipment (such as laser detection, etc.) to perform verticality detection on the polished end surface. This not only increases the investment cost of production equipment, but also limits the practicality of the grinding device, making it difficult to meet diverse production and manufacturing needs. Summary of the Invention

This not only reduces the investment cost of production equipment, but also greatly improves the practicality of the grinding device, and can meet diverse production and manufacturing needs.

[0035] The present invention opens a detection chamber 403 in the shell 401. When the metal bar extends into the detection chamber 403, the detection rod 4032 is pulled out, and the metal bar is pressed against the contact plate 404, and the end face of the contact plate 404 is in contact with the end face of the metal bar. At this time, the detection rod 4032 is inserted back into the shell 401. If the detection rod 4032 can be inserted back into the reference groove 4041, it proves that the end face of the metal bar is not tilted. If the detection rod 4032 cannot be inserted back into the reference groove 4041, it proves that the contact plate 404 attached to the end face of the metal bar is tilted, and further proves that the end face of the metal bar is polished and tilted.

[0036] The specific usage and function of this embodiment are as follows: In the present invention, Figures 1 to 9As shown, the metal bars to be processed are inserted into the base 301 through the slots 3011, so that the two groups of metal bars are staggered in a cross-shaped structure, and the adjusting screw 302 is rotated to drive the clamping block 3021 to slide in the slots 3011, so that the metal bars are firmly clamped and fixed on the base 301. At this time, the positioning hole 203 in the linkage rod 201 is plugged into the limiting rod 1031 in the retaining rod 103 to limit the linkage rod 201 in the frame 101. The equipment is started, and according to the program setting of the grinding device, the screw in the side plate 104 can drive the movable frame 1042 to slide, and the sliding The housing 401 of the driving mechanism 4 moves to a suitable position, so that the metal bar extends into the grinding chamber 402 in the housing 401. The grinding disc 4021 in the grinding chamber 402 is connected to the motor and rotates at high speed to grind the end face of the metal bar. The debris generated by the grinding falls into the collection box 105 and is collected by the collection box 105. When the grinding of the metal bar at the workstation on the base 301 is completed, the limit rod 1031 is pulled out and the base 301 is rotated. Since the guide block 1021 on the vertical rod 102 slides with the guide groove 202 on the linkage rod 201, the linkage rod 201 is in the vertical rod 102. The upper part of the base 301 is rotated and raised at the same time, and the metal bar of the lower station of the base 301 is raised to the processing position. At this time, the metal bar of the lower station enters the grinding chamber 402 to continue grinding. At the same time, the operator can remove the metal bar that has been processed at the upper station and reinsert the bar to be processed for fixing. After the grinding of the metal bar of the lower station is completed, the base 301 is rotated again to send the newly inserted metal bar of the upper station to the processing position for grinding. Each time the grinding of the metal bars of the upper and lower stations is completed, the grinding device can move the movable frame 1042 and the shell 402 in sequence according to the program setting. 01. After inserting the metal bar into the inspection chamber 403, first pull out the inspection rod 4032, then press the metal bar against the contact plate 404. After the end face of the contact plate 404 contacts the end face of the metal bar, insert the inspection rod 4032 back into the shell 401. If the inspection rod 4032 can be inserted back into the reference groove 4041, it proves that the end face of the metal bar is flat and not tilted; if the inspection rod 4032 cannot be inserted back into the reference groove 4041, it proves that the end face of the metal bar has been ground and tilted, and rework is required. Through the above process, efficient grinding and inspection of the end face of the metal bar can be achieved.
