Abstract
Description
Technical Field
[0001] This application relates to the field of auxiliary testing tooling, and more specifically, to a manual auxiliary testing tooling for high-density compacted blocks. Background Technology
[0002] A fuel pellet is a cylindrical element that makes up a nuclear fuel rod. It is a high-density briquette made by powder pressing, sintering, and grinding. Due to limitations in the manufacturing process, surface defects such as chipping and missing corners are unavoidable during powder pressing and sintering. Defective fuel pellets entering the grinding process can cause grinding machine jamming. Grinding machine jamming is generally handled manually, which is time-consuming and labor-intensive.
[0003] Currently, defect detection equipment is generally used for inspection, as can be found in Chinese patent document CN219038869U. However, to avoid errors caused by equipment inspection, a manual re-inspection process is usually set up to ensure the accuracy of the inspection and reduce errors. However, during the manual re-inspection process, it is necessary to check the coaxiality of the pressure block, etc., and the pressure block needs to be installed in a pre-made mold. The pressure block needs to be positioned and installed manually, which is a relatively cumbersome operation. Therefore, a high-density briquette for manual inspection is needed to solve the above problems. Utility Model Content
[0004] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.
[0005] To address the technical problems mentioned in the background section, some embodiments of this application provide a high-density press block manual auxiliary testing fixture, comprising: a base, on which a second support member and a first support member are fixedly mounted and slidably mounted, the first support member being located on one side of the second support member, and placement grooves being formed on both the first and second support members; a press block, placed within the placement grooves of the first and second support members; a sliding table, slidably mounted on the base, with a mounting bracket mounted on the sliding table; a dial indicator, mounted on the mounting bracket, for testing the press block; a motor fixedly mounted on the second support member on the side away from the first support member, with an abutment fixedly connected to the motor's power output end, the abutment located within the placement groove; a limiting head mounted on the first support member on the side away from the second support member, with a ejector pin fixedly connected to the limiting head, the limiting head having two extreme positions: when the limiting head is at the first extreme position, the ejector pin is located within the placement groove and coaxially arranged with the abutment; when the limiting head is at the second extreme position, the ejector pin is not located within the placement groove, and the limiting head is offset from the placement groove.
[0006] Furthermore, a rotating handle is rotatably mounted on the base, and a first conical wheel is coaxially and fixedly connected to the rotating handle. A lead screw is rotatably mounted on the base, passing through the sliding table, and a second conical wheel is fixedly connected to one end of the lead screw. The second conical wheel meshes with the first conical wheel.
[0007] Furthermore, a connecting rod passing through the second support member is provided on the first support member, and a retaining ring is fixedly connected to the far end of the connecting rod. A spring is provided between the retaining ring and the first support member, and the two ends of the spring are fixedly connected to the retaining ring and the first support member, respectively. A pushing part for pushing the retaining ring is fixedly connected to the sliding table.
[0008] Furthermore, a fixed cylinder is fixedly provided on the limiting head, and the fixed cylinder has a guide wall. A fixed rod is fixedly connected to the first support member. The fixed rod has one end located inside the guide wall. One end of the fixed rod abuts against the side wall of the guide wall and causes the limiting head to rotate around the axis of the rotating wheel.
[0009] Furthermore, the guide wall has a horizontal section extending along the axis of the connecting rod and a guide section extending spirally around the axis of the connecting rod. The horizontal section is located on the side away from the first support member, and the guide section is located on the side close to the first support member. When the limiting head and the fixing cylinder move away from the first support member, the fixing rod slides from the horizontal section to the guide section, and the guide section and the horizontal section are smoothly connected.
[0010] Furthermore, a guide post is provided between the first support member and the second support member, the guide post passes through the first support member and the second support member, the first support member and the guide post slide together, and a locking handle is installed on the first support member to limit the movement of the first support member and the guide post.
[0011] Furthermore, a rotating wheel that contacts the side wall of the pressure block is rotatably mounted on the side wall of the placement groove.
[0012] The beneficial effects of this application are as follows: 1. The sliding table, mounting bracket, and dial indicator are used to move the mounting bracket, which in turn moves the dial indicator along the axis of the pressure block to measure various positions on the surface of the pressure block.
[0013] 2. The motor, abutment, limit head, and ejector pin are configured to power the pressing block by outputting power through the motor. At the same time, the ejector pin abuts against one end of the pressing block to limit its movement. This allows the pressing block to be rotated by rotating the pressing block when the dial indicator is used to test the coaxiality of the pressing block at various positions on its surface.
[0014] 3. With the fixed cylinder, fixed rod and guide wall set up, when the sliding table moves to the end of the stroke, the pressure block detection is completed. The set push part pushes the retaining ring, so that the connecting rod and the rotating wheel move, which in turn drives the limit head and the fixed cylinder to move. The limit head no longer limits the pressure block. At the same time, the guide wall abuts against one end of the fixed rod, so that the limit head rotates. The limit head is misaligned with the placement groove, which makes it easy to remove the pressure block from the axial direction. Attached Figure Description

[0023] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.
[0024] Reference Figure 1-4A high-density compressed block manual auxiliary testing fixture includes: a base 10, a first support member 11, a second support member 12, a compressed block 13, a sliding table 15, a dial indicator 16, and a mounting frame 14. The second support member 12 and the first support member 11, which is slidably mounted on the base 10, are fixedly mounted on the base 10. The first support member 11 is located to one side of the second support member 12. Placement grooves, which are V-shaped grooves, are formed on both the first and second support members 11, and the compressed block 13 is placed within these grooves. The sliding table 15 is slidably mounted on the base 10, and the mounting frame 14 is mounted on the sliding table 15. The dial indicator 16 is mounted on the mounting frame 14 to test the compressed block 13. The mounting frame 14 is a dial indicator mounting frame, which can be referenced from existing technology. A motor 21 is fixedly mounted on the second support member 12, located away from the first support member 11. A contact joint 22 is fixedly connected to the power output end of the motor 21, and the contact joint 22 is located within the placement groove. A rotating wheel 24 is rotatably mounted on the side wall of the placement groove, contacting the side wall of the pressure block 13. This allows the pressure block 13 to rotate around its own axis within the placement groove. A limiting head 23 is mounted on the side of the first support member 11 away from the second support member 12. A pin portion 33 is fixedly connected to the limiting head 23. The limiting head 23 has two extreme positions. When the limiting head 23 is in the first extreme position, the pin portion 33 is located within the placement groove and coaxially arranged with the abutment 22. When the limiting head 23 is in the second extreme position, the pin portion 33 is not located within the placement groove, and the limiting head 23 is offset from the placement groove. When the pressure block 13 is placed between the first support member 11 and the second support member 12, one end of the pressure block 13 abuts against the abutment 22, and the other end of the pressure block 13 abuts against the pin portion 33. The rotation of the abutment 22 drives the pressure block 13 to rotate.
[0025] A rotating handle 17 is rotatably mounted on the base 10. A first conical wheel 18 is coaxially fixedly connected to the rotating handle 17. A lead screw 20, passing through a sliding table 15, is rotatably mounted on the base 10. A second conical wheel 19 is fixedly connected to one end of the lead screw 20, and the second conical wheel 19 meshes with the first conical wheel 18. By rotating the rotating handle 17, the lead screw 20 is driven to rotate under the action of the first conical wheel 18 and the second conical wheel 19, thereby causing the sliding table 15 to move along the axis of the pressure block 13. This causes the measuring head of the dial indicator 16 to move on the surface of the pressure block 13, allowing for the measurement of various positions on the surface of the pressure block 13.
[0026] A connecting rod 25 passing through the second support member 12 is provided on the first support member 11. A retaining ring 26 is fixedly connected to the far end of the connecting rod 25. A spring 29 is provided between the retaining ring 26 and the first support member 11. The two ends of the spring 29 are fixedly connected to the retaining ring 26 and the first support member 11, respectively. A pushing part 28 that pushes the retaining ring 26 is fixedly connected to the sliding table 15. After the dial indicator 16 completes the test on the pressure block 13, the sliding table 15 continues to move until the pushing part 28 pushes the retaining ring 26.
[0027] A fixed cylinder 30 is fixedly mounted on the limiting head 23. The fixed cylinder 30 has a guide wall 32. A fixed rod 31 is fixedly connected to the first support member 11. The fixed rod 31 is located inside the guide wall 32, with one end abutting against the side wall of the guide wall 32, causing the limiting head 23 to rotate around the axis of the rotating wheel 24. The guide wall 32 has a horizontal section extending along the axis of the connecting rod 25 and a guide section extending spirally around the axis of the connecting rod 25. The horizontal section is located on the side away from the first support member 11, and the guide section is located on the side close to the first support member 11. When the limiting head 23 and the fixed cylinder 30 move away from the first support member 11, the fixed rod 31 slides from the horizontal section to the guide section, and the guide section is smoothly connected to the horizontal section. When the retaining ring 26 moves under the push of the pusher 28, it will compress the connecting rod 25 and cause one end of the fixing rod 31 to move from the horizontal section to the guide section. Then, under the action of the guide section, the fixing cylinder 30 and the ejector pin 33 will rotate, causing the spring 29 to twist. The limiting head 23 will be misaligned with the placement groove, making it easier for the pressure block 13 to be removed axially.
[0028] A guide post 27 is provided between the first support member 11 and the second support member 12, passing through both. The first support member 11 and the guide post 27 are in sliding engagement. A locking handle 34 is installed on the first support member 11 to limit the movement of the first support member 11 and the guide post 27. By adjusting the distance between the first support member 11 and the second support member 12, pressure blocks 13 of different lengths can be accommodated. The locking handle 34 and the guide post 27 can be referenced from existing technology.
[0029] Working process or usage method: 1. Place the pressure block 13 into the placement slots on the first support member 11 and the second support member 12. By rotating the rotating handle 17, the sliding table 15 moves to the initial position, and the detection head of the dial indicator 16 abuts against the surface of the pressure block 13. At this time, the motor 21 is started to output power, so that the abutment 22 drives the pressure block 13 to rotate. At the same time, the ejector pin 33 abuts against one end of the pressure block 13 to limit the pressure block 13. Meanwhile, by rotating the rotating handle 17, the sliding table 15 moves along the axis of the pressure block 13 to detect various positions on the surface of the pressure block 13.
[0030] 2. When the sliding table 15 reaches the end of its stroke, the pressure block 13 completes the detection. The pusher 28 pushes the retaining ring 26, causing the connecting rod 25 and the rotating wheel 24 to move, which in turn drives the limiting head 23 and the fixing cylinder 30 to move. One end of the fixing rod 31 first moves within the horizontal section of the guide wall 32, so that the ejector pin 33 no longer abuts against one end of the pressure block 13. Then, within the guide section of the guide wall 32 of the fixing rod 31, the limiting head 23 and the fixing cylinder 30 deflect, and the limiting head 23 is misaligned with the placement groove, making it easier to remove the pressure block 13 axially.
[0031] 3. When it is necessary to test pressure blocks 13 of different lengths, the distance between the first support member 11 and the second support member 12 is adjusted to accommodate pressure blocks 13 of different lengths, and then the locking handle 34 is used to limit the first support member 11 and the second support member 12.
