[0036] This embodiment provides a ring alignment fixture for clamping a ring. The outer peripheral wall of the ring has multiple protrusions spaced circumferentially along the ring, such as... Figure 1 As shown, the ring alignment fixture includes a worktable 100, a positioning block 200, a locking device 300, and a calibration scale 400. The worktable 100 is used to support the ring. The positioning block 200 is disposed on the worktable 100 and has a positioning groove 210. One of the multiple protrusions is inserted into the positioning groove 210. The locking device 300 is disposed on the worktable 100 relative to the positioning block 200. The locking device 300 is used to press against the inner wall of the ring to fix the ring on the worktable 100. The calibration scale 400 is disposed on the worktable 100 and is used to indicate the roundness of the ring.
[0037] The ring alignment fixture provided in this embodiment has a simple structure and low manufacturing cost. After the ring is fixed on the worktable 100, the deformation of the ring end can be repaired by the alignment wrench. The alignment scale 400 on the worktable 100 can indicate the roundness deviation of the ring in real time, providing a clear roundness indication for the operator to make precise adjustments to the ring so that the ring meets the qualified standard, reduces product abnormalities, lowers the scrap rate, and improves the stability of product processing quality.
[0038] Optionally, the locking device 300 includes a driving member 310 and a locking block 320. The driving member 310 is disposed on the worktable 100, and the locking block 320 is slidably disposed on the worktable 100 relative to the positioning block 200. The locking block 320 is connected to the output end of the driving member 310. The driving member 310 is used to drive the locking block 320 to press against the inner wall of the ring, so that the locking block 320 and the positioning block 200 jointly clamp part of the ring. The locking device 300 controls the sliding of the locking block 320 through the driving member 310, so that it can accurately press against the inner wall of the ring, forming a firm clamping effect together with the positioning block 200, thereby improving the stability of the ring.
[0039] In this embodiment, the driving component 310 is a locking screw. The locking screw can be a locking screw with a light hole at the bottom of the locking block. The locking screw passes through the light hole at the bottom of the locking block 320 and is threaded to the worktable 100. By tightening the locking screw, the locking block 320 can be driven to approach the positioning block to clamp the ring. Furthermore, designing the driving component 310 as a locking screw makes full use of its simple and reliable structural characteristics, effectively reducing production costs and manufacturing difficulties.
[0040] In other embodiments, the driving component 310 can be a driving cylinder. The cylinder body of the driving cylinder is set on the worktable 100. The locking block 320 is connected to the piston rod of the driving cylinder. The driving cylinder drives the piston rod to move by air pressure, which drives the locking block 320 to achieve quick clamping or releasing operation. This significantly improves the automation level of the fixture operation, greatly reduces manual intervention, and is suitable for the needs of mass production and continuous operation.
[0041] It should be noted that the output force of the drive cylinder can be precisely controlled by adjusting the air pressure to ensure that the force applied by the locking block 320 meets the actual needs of the ring. This not only avoids damage to the ring due to excessive locking force, but also provides sufficient fixing force to ensure clamping stability.
[0042] Optionally, the contact surface between the locking block 320 and the inner wall of the ring is an arc surface, allowing the locking block 320 to align more naturally with the inner wall of the ring. This eliminates the need for precise angle adjustments, reducing assembly time and improving ease of operation. Furthermore, the arc surface design significantly reduces pressure concentration at the contact point, preventing indentations, scratches, or deformation of the inner wall of the ring due to excessive locking force.
[0043] Optionally, the calibration scale 400 includes a scale plate 410, which is detachably mounted on the worktable 100. The scale plate 410 has a plurality of scale lines 420, which are spaced apart radially along the ring. The scale lines 420 on the scale plate 410, spaced apart radially along the ring, can accurately display the roundness deviation of the ring. By observing the correspondence between the scale lines 420 and the outer circumference of the ring, the operator can quickly determine the degree of deformation of the ring, thereby efficiently completing the calibration.
[0044] Optionally, the worktable 100 is provided with a groove, and the scale plate 410 is set in the groove to prevent it from moving or shifting due to external force or vibration during use, and to ensure that the scale plate 410 is always in an accurate position, thereby improving the reliability and accuracy of calibration measurement.
[0045] In this embodiment, the detachable design of the scale plate 410 allows the device to quickly replace the appropriate scale plate 410 according to different specifications or types of rings, enhancing the applicability and versatility of the ring calibration fixture. Specifically, the edge of the scale plate 410 is provided with a snap-fit structure that cooperates with the slot on the worktable 100, enabling quick assembly and disassembly through simple snap-fit and pull-out actions.
[0046] In other embodiments, the workbench 100 is designed with an embedded slot, and the bottom of the scale plate 410 is provided with a corresponding plug-in block. The scale plate 410 is fixed by inserting the plug-in block into the slot. This design facilitates disassembly and assembly, while ensuring the accurate position of the scale plate 410.
[0047] Optionally, the positioning block 200 and locking block 320 are made of non-metallic material. Non-metallic materials prevent the positioning block 200 and locking block 320 from scratching the surface of the ring when they contact it, making them particularly suitable for calibration operations on rings requiring precision machining or high aesthetic standards. Specifically, the positioning block 200 can be made of polyurethane, nylon, polytetrafluoroethylene (PTFE), rubber, or silicone. The locking block 320 can also be made of polyurethane, nylon, PTFE, rubber, or silicone. The materials of the positioning block 200 and locking block 320 can be selected to suit different processing environments and quality requirements.
[0048] Optionally, the width of the positioning groove 210 matches the width of the protrusion. Matching the width of the positioning groove 210 with the width of the protrusion can ensure that the protrusion is firmly embedded in the positioning groove 210, avoiding shaking or displacement of the ring during clamping, thereby improving the accuracy of ring alignment.
[0049] Optionally, the ring alignment fixture also includes an insertion adjustment plate. Multiple slots are spaced apart on the side wall of the positioning groove 210 along the depth direction of the positioning groove 210. The insertion adjustment plate can be inserted into any slot to adjust the depth of the positioning groove 210, thereby making the positioning block 200 compatible with protrusions of different lengths and improving the adaptability of the ring alignment fixture.
[0050] Optionally, the workbench 100 is equipped with a height-adjustable support at its bottom, which supports the workbench 100. The height-adjustable design of the support allows the operator to adjust the height of the workbench 100 according to actual needs, adapting to the working habits of different operators, enabling operators to work at a more ergonomic height, reducing bending or uncomfortable postures, reducing labor intensity, and improving work comfort.
[0051] Specifically, the support includes a frame and a lifting cylinder. The lifting cylinder is mounted on the frame, and its piston rod is connected to the worktable 100. The lifting cylinder directly drives the worktable 100 to rise or fall.
[0052] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
