Multifunctional nuclear power metal rod end face polishing device

Abstract

This invention provides a multifunctional end-face grinding device for nuclear power metal rods, relating to the field of grinding device technology. It includes an installation mechanism that combines grinding and inspection functions. When the metal rod is inserted into the inspection chamber, the inspection rod is pulled out, causing the end face of the metal rod to align with the contact plate. The inspection rod is then inserted back in. By determining whether the inspection rod can be inserted directly into the reference slot, the tilting of the metal rod end face can be quickly detected. This design eliminates the need for additional dedicated inspection equipment, achieving both grinding and inspection functions on the same device. It solves the problem that existing grinding devices have relatively limited functionality and typically require expensive additional inspection equipment (such as laser inspection) to check the perpendicularity of the ground end face after grinding. This not only increases the cost of production equipment but also limits the practicality of the grinding device, making it difficult to meet diverse production and manufacturing needs.

Description

Technical Field

[0001] This invention relates to the field of grinding equipment technology, and in particular to a multifunctional grinding device for the end face of nuclear power metal rods. Background Technology

[0002] In the nuclear power field, metal rods are key structural and functional materials. Their processing precision and surface quality directly affect the safety and stability of nuclear power plant operation. During the manufacturing process of metal rods, due to the influence of cutting, forging and other processing techniques, the two ends of the rods usually have defects such as uneven end faces, residual burrs on the edges, and oxide layer adhesion. These defects not only reduce the appearance quality of the metal rods, but may also bring serious safety hazards during subsequent assembly and use. Specifically, uneven end faces make it difficult to achieve a tight fit when the rods are connected, thus affecting the mechanical properties and stability of the overall structure; while the presence of burrs and oxide layers will weaken the corrosion resistance of the rods and shorten the actual service life of nuclear power plant equipment. Therefore, before metal rods are put into use, it is necessary to use intelligent grinding equipment to grind and process their two end faces.

[0003] Currently, existing metal bar end-face grinding devices on the market still have many technical shortcomings in practical applications:

[0004] Firstly, existing grinding equipment generally adopts a single-set processing mode. After each set of metal rods is ground, it is necessary to perform operations such as loosening and unloading, reloading and fixing in sequence. These auxiliary processes consume a lot of time and significantly extend the overall processing cycle, making it difficult to improve production efficiency and meet the needs of large-scale production.

[0005] Secondly, the existing grinding equipment has a relatively simple function. After the grinding operation is completed, it is usually necessary to equip it with expensive testing equipment (such as laser testing) to test the perpendicularity of the ground end face. This not only increases the investment cost of production equipment, but also limits the practicality of the grinding equipment and makes it difficult to meet the diverse production and manufacturing needs. Summary of the Invention

[0006] To address the above problems, one objective of this invention is to overcome these shortcomings, and more specifically, to provide a multifunctional end-face grinding device for nuclear power metal rods, which can shorten the processing time of the entire batch of metal rods and, after grinding, can inspect the processing quality of the end face.

[0007] In a first aspect, this invention provides a multifunctional end-face grinding device for nuclear power metal rods, specifically comprising: an installation mechanism; the installation mechanism includes a frame, a fixing plate, and a vertical rod, the frame being a rectangular structure; the fixing plate being located at the middle position inside the frame; the vertical rod being fixedly located at the middle position of the upper end of the fixing plate, and guide blocks being provided at both ends of the vertical rod; the installation mechanism is provided with a linkage mechanism, the linkage rod of the linkage mechanism being sleeved on the outside of the vertical rod, and the linkage rod passing through a retaining rod inside the frame, the guide groove inside the linkage rod slidingly engaging with the guide block, and the positioning hole inside the linkage rod inserting into the limiting rod inside the retaining rod; the linkage mechanism is provided with a fixing mechanism, the base of the fixing mechanism being fixedly installed on the top of the linkage rod; the installation mechanism is provided with two sets of sliding mechanisms, each sliding mechanism including a housing, the housing being a rectangular structure, and the housing being slidably installed in a movable frame at the side end of the frame.

[0008] Preferably, the installation mechanism includes: a retaining rod and a limiting rod; the retaining rod is located in the middle of the frame body and is directly above the fixing plate, and a circular through hole is opened in the middle of the retaining rod; the limiting rod is located on the front side of the retaining rod and passes through the front end of the frame body.

[0009] Preferably, the installation mechanism includes: side plates, docking slots, and movable frames; the side plates are symmetrically arranged on both sides of the frame, and a motor screw is rotatably installed inside the side plates; the docking slots are symmetrically opened on both sides of the side plates; the movable frames are slidably installed on the upper end of the side plates by screws, and the middle position of the movable frames is hollow.

[0010] Preferably, the installation mechanism includes: a collection box and hook plates; the collection box is located at the lower end of each set of side plates; the hook plates are symmetrically arranged on both sides of the upper end of the collection box, and the hook plates are inserted into the docking groove.

[0011] Preferably, the linkage mechanism includes: a linkage rod, a guide groove, and positioning holes; the linkage rod is a cylindrical structure; the guide groove is spirally formed on both sides of the inside of the linkage rod; the positioning holes are staggered and transversely formed inside the linkage rod, and the linkage rod can rotate 90° on the upright by the movement of the guide block in the guide groove.

[0012] Preferably, the fixing mechanism includes: a base and slots; the base is a rectangular structure; the slots are staggered at the upper and lower ends of the base, and the slots extend horizontally through the base.

[0013] Preferably, the fixing mechanism includes: an adjusting screw and a clamping block; the adjusting screw is rotatably mounted on both sides inside the base; the clamping block is slidably mounted on both sides inside each set of slots, and the clamping block is threadedly connected to the adjusting screw.

[0014] Preferably, the sliding mechanism includes: a grinding chamber and a grinding disc; the grinding chamber is located inside the left side of the housing, and the lower end of the grinding chamber penetrates the housing; the grinding disc is rotatably mounted inside the grinding chamber, and the grinding disc is connected to a motor.

[0015] Preferably, the sliding mechanism includes: a detection chamber, a mounting groove, and a detection rod; the detection chamber is located inside the right side of the housing; the mounting groove is located deep inside the detection chamber; the detection rod is inserted into the rear side of the housing, and the front end of the detection rod is inserted into the mounting groove.

[0017] 1. In this invention, through the coordinated design of the linkage mechanism and the fixing mechanism, the linkage rod is rotatably installed on the upright. By utilizing the sliding cooperation between the guide block and the guide groove, after the metal rod at the upper station of the base is processed, only the limiting rod needs to be pulled out and the base rotated. The linkage rod can then rise while rotating, sending the metal rod at the lower station to the processing position. During this process, the processed metal rod at the upper station can be disassembled and replaced simultaneously, realizing parallel operation of processing and loading / unloading. Compared with the existing mode of sequentially loosening, unloading, reloading, and fixing after processing a single set, this greatly reduces the time spent on auxiliary processes, effectively shortens the overall processing cycle, significantly improves production efficiency, and meets the needs of large-scale production.

[0018] 2. In this invention, by combining grinding and inspection functions, after the metal rod is inserted into the inspection chamber, the inspection rod is pulled out, and then the end face of the metal rod is brought into contact with the contact plate. Then, the inspection rod is inserted back in. By judging whether the inspection rod can be inserted straight into the reference groove, it is possible to quickly detect whether the end face of the metal rod is tilted. This design does not rely on special inspection equipment. The inspection of the end face of the metal rod can be achieved with this simple structure. This not only reduces the investment cost of production equipment, but also greatly improves the practicality of the grinding device and can meet the diverse production and manufacturing needs.

[0052] This invention rotatably mounts the linkage rod 201 onto the upright rod 102, and allows the guide block 1021 on the upright rod 102 to slide into the guide groove 202 on the linkage rod 201. After the metal rod at the upper station of the base 301 is processed, the limiting rod 1031 is pulled out, and the base 301 is rotated. The linkage rod 201 can rise while rotating on the upright rod 102, thereby raising the metal rod at the lower station of the base 301 to the processing position. At this time, while the metal rod at the lower station is being ground, the metal rod at the upper station that has already been processed can be disassembled and replaced. Thus, after the metal rod at the lower station is processed, it can be moved to another station for processing.

[0053] As a fifth embodiment of the present invention, based on embodiment 1, such as Figure 8 and Figure 9As shown, the sliding mechanism 4 includes: a grinding chamber 402 and a grinding disc 4021; the grinding chamber 402 is located inside the left side of the housing 401, and the lower end of the grinding chamber 402 penetrates through the housing 401; the grinding disc 4021 is rotatably mounted inside the grinding chamber 402, and the grinding disc 4021 is connected to a motor; a detection chamber 403, a mounting groove 4031, and a detection rod 4032; the detection chamber 403 is located inside the right side of the housing 401; the mounting groove 4031 is located deep inside the detection chamber 403; the detection rod 4032 is inserted into the rear side of the housing 401, and the front end of the detection rod 4032 is inserted into the mounting groove 4031; a contact plate 404 and a reference groove 40 41; The contact plate 404 is located inside the detection chamber 403, and a spherical structure is fixedly provided at the rear end of the contact plate 404. The spherical structure is engaged in the mounting groove 4031, and the contact plate 404 can rotate inside the detection chamber 403; The reference groove 4041 is opened on the rear side of the spherical structure behind the contact plate 404, and the reference groove 4041 is inserted into the detection rod 4032; A housing 401 is provided, and a metal rod can be inserted into the housing 401 for processing and detection; A grinding chamber 402 is provided, and a grinding disc 4021 is installed in the grinding chamber 402. When the metal rod is inserted into the grinding chamber 402, the end face of the metal rod can be ground by means of the grinding disc 4021 inside.

[0054] This invention utilizes a detection chamber 403 within the housing 401. When a metal rod is inserted into the detection chamber 403, a detection rod 4032 is pulled out, causing the metal rod to abut against a contact plate 404, with the end face of the contact plate 404 contacting the end face of the metal rod. Then, the detection rod 4032 is inserted back into the housing 401. If the detection rod 4032 can be inserted back into the reference groove 4041, it proves that the end face of the metal rod is not tilted. If the detection rod 4032 cannot be inserted back into the reference groove 4041, it proves that the contact plate 404, which is attached to the end face of the metal rod, is tilted, thus proving that the end face of the metal rod has been ground tilted.

[0055] The specific usage and function of this embodiment are as follows:

[0056] In this invention, such as Figures 1 to 9As shown, the metal rods to be processed are inserted into the base 301 through the slot 3011, so that the two sets of metal rods are staggered in a cross shape. Rotating the adjusting screw 302 causes the clamping block 3021 to slide within the slot 3011, thereby firmly clamping and fixing the metal rods onto the base 301. At this time, the positioning hole 203 in the linkage rod 201 engages with the limiting rod 1031 in the retaining rod 103, limiting the linkage rod 201 within the frame 101. The equipment is started, and according to the program settings for the grinding device, the screw in the side plate 104 can drive the movable frame 1042 to slide, thus fixing the metal rods. The housing 401 of the moving mechanism 4 moves to a suitable position, allowing the metal rod to extend into the grinding chamber 402 inside the housing 401. The grinding disc 4021 inside the grinding chamber 402 is connected to a motor and rotates at high speed to grind the end face of the metal rod. The grinding debris falls into the collection box 105 and is collected by the collection box 105. When the metal rod at the work station on the base 301 is finished being ground, the limit rod 1031 is pulled out, and the base 301 is rotated. Due to the sliding engagement between the guide block 1021 on the upright 102 and the guide groove 202 on the linkage rod 201, the linkage rod 201 moves along the upright 102. While rotating upwards, the base 301 rises, raising the metal rod at the lower station to the processing position. At this time, the lower station metal rod enters the grinding chamber 402 for further grinding. Simultaneously, the operator can disassemble the metal rod already processed at the upper station and reinsert it for processing. After the lower station metal rod is ground, the base 301 rotates again to send the newly inserted upper station metal rod to the processing position for grinding. Each time the metal rods at the upper and lower stations are ground, the grinding device, according to the programmed settings, can sequentially move the movable frame 1042 and the housing 4. 01. After inserting the metal rod into the testing chamber 403, first pull out the testing rod 4032, then place the metal rod against the contact plate 404. After the end face of the contact plate 404 contacts the end face of the metal rod, insert the testing rod 4032 back into the housing 401. If the testing rod 4032 can be inserted back into the reference groove 4041, it proves that the end face of the metal rod is flat and has not tilted. If the testing rod 4032 cannot be inserted back into the reference groove 4041, it proves that the end face of the metal rod has been ground tilted and needs to be reworked. Through the above process, efficient grinding and testing of the end face of the metal rod can be achieved.
