Description

Technical Field

[0001] This utility model relates to the field of cookware manufacturing, and in particular to a multifunctional positioning fixture for laser marking. Background Technology

[0002] In cookware production, laser marking is required on the handle and lugs. During laser marking, the handle and lugs need to be positioned. Existing positioning fixtures can only position a single structure. The positioning fixtures need to be replaced to meet the requirements of laser marking on the handle and lugs. To solve the above problems, a multi-functional positioning fixture for laser marking is proposed. Utility Model Content

[0003] The purpose of this invention is to solve the problem that existing positioning fixtures can only position a single structure and cannot be used simultaneously.

[0004] The present invention adopts the following technical solution:

[0005] A multi-functional positioning fixture for laser marking includes a base frame, a positioning seat on the base frame, a truncated pyramid on the positioning seat, a slide rail between the truncated pyramids, a slider inside the slide rail, a limiting part on the slider, a bolt on the limiting part, a mounting bracket on the outside of the positioning seat, and the end of the bolt passing through the mounting bracket and connecting to a rotating handle.

[0006] Furthermore, the slide is cross-shaped, with any side of the slide extending upward to form a V-groove. The V-grooves of two adjacent sides combine to form a truncated pyramid. The sides where the two V-grooves meet form a contact strip. The contact strip faces the center of the cross-shaped slide. There are four truncated pyramids, each with a contact strip. The contact strip extends upward to a platform with a through hole for inserting a screw to connect with the base frame. The platform is located in the middle of the truncated pyramid.

[0007] Furthermore, the slide has a trapezoidal cross-section, and the slider matches the shape of the slide. There are three sliders, which are located on the three sides of the cross-shaped slide. A limiting part is fixedly provided on the slider. The limiting part includes a clamping block. There are two clamping blocks, which are set on two opposing sliders. One side of the clamping block is V-shaped. The V-shaped areas of the two clamping blocks are arranged opposite each other to abut against the lug body. The bottom of the clamping block is inclined to cooperate with the V-shaped groove. The other end of the clamping block has a slot, and the nut part of the bolt is located in the slot of the clamping block.

[0008] Furthermore, the limiting part also includes a V-block and a limiting stud. The V-block is disposed on the slider between the two clamping blocks. The V-block is perpendicular to the two clamping blocks. The front end of the V-block has a groove, and the front end of the groove has a limiting stud, which is threaded onto the slider to limit the pot handle body. The rear end of the V-block has a slot, and the nut part of the bolt is located in the slot of the V-block.

[0009] Furthermore, the mounting bracket is fixed to the positioning seat by a support column. There are three mounting brackets, which are located on the outside of the positioning seats where the three sliders are located. The upper end of the mounting bracket has an opening for the bolt shank to pass through.

[0010] Furthermore, the bolt has a rotating handle threaded onto its end. The rotating handle is located on the outside of the mounting bracket and is used to drive the clamping block and V-block to move on the slide rail via the slider. A spring is sleeved on the shank of the bolt. One end of the spring abuts against the mounting bracket, and the other end abuts against the clamping block and V-block, which is used to limit the rotation handle.

[0011] Furthermore, the base frame has an adjustment rod for position adjustment;

[0012] Furthermore, the base frame has a limiting stop bar that restricts the movement of the base frame.

[0013] The beneficial effects of this utility model are:

[0014] With the cross-shaped slide and movable slider, the combination design of the clamp and V-block can simultaneously adapt to the positioning needs of pot handles and hanging ears without changing the clamps. The V-shaped surface of the clamp matches the shape of the hanging ear, and the V-block, together with the limiting stud, can accurately position pot handles of different sizes, covering a variety of cookware models.

[0015] The rotating handle drives the bolt to achieve rapid displacement of the clamping block and V-block. The spring system maintains a constant clamping force after adjustment to prevent parts from loosening during coding. The trapezoidal cross section of the slide and the matching design of the slider ensure smooth movement and anti-deviation capability.

[0016] The design of the adjustment rod and limit stop on the base frame allows for fine-tuning of the entire fixture, ensuring precise matching of its relative position with the laser marking equipment to meet the requirements of different marking positions. Attached Figure Description

[0028] Example 1

[0029] This utility model provides a multi-functional positioning fixture for laser marking, including a base frame 1, a positioning seat 2 on the base frame 1, a truncated pyramid 3 on the positioning seat 2, a slide rail 4 between the truncated pyramids 3, a slider 8 inside the slide rail 4, a limiting part 9 on the slider 8, a bolt 13 on the limiting part 9, a mounting bracket 7 on the outside of the positioning seat 2, and the end of the bolt 13 passes through the mounting bracket 7 and is connected to the rotating handle 14.

[0030] Furthermore, the slide 4 is cross-shaped, and any side of the slide 4 extends upward to form a V-groove 5. The V-grooves 5 of two adjacent sides combine to form a frustum 3. The sides where the two V-grooves 5 contact each other form a contact strip 6. The contact strip 6 faces the center of the cross-shaped slide 4. There are four frustums 3, and each frustum 3 has a contact strip 6. The contact strip 6 extends upward to a platform. The platform has a through hole for inserting a screw to connect with the base frame 1. The platform is located in the middle of the frustum 3.

[0031] Furthermore, the slide 4 has a trapezoidal cross section, and the slider 8 matches the shape of the slide 4. There are three sliders 8, which are located on the three sides of the cross-shaped slide 4. A limiting part 9 is fixedly installed on the slider 8. The limiting part 9 includes a clamping block 10. There are two clamping blocks 10, which are set on two opposing sliders 8. One side of the clamping block 10 is V-shaped, and the V-shaped part of the clamping block 10 has an arc surface. The V-shaped areas of the two clamping blocks 10 are arranged opposite each other to abut against the hanging ear body 17. The bottom of the clamping block 10 is inclined to cooperate with the V-shaped groove 5. The other end of the clamping block 10 has a groove, and the nut part of the bolt 13 is located in the groove of the V-shaped groove 5.

[0032] Furthermore, the limiting part 9 also includes a V-block 11 and a limiting stud 12. The V-block 11 is disposed on the slider 8 between the two clamping blocks 10 and the slider 8. The V-block 11 is perpendicular to the two clamping blocks 10. The front end of the V-block 11 has a groove. The groove at the front end of the V-block 11 has no arc surface. The front end of the groove has a limiting stud 12, which is threaded onto the slider 8 to limit the pot handle body 16. The rear end of the V-block 11 has a slot. The nut part of the bolt 13 is located in the slot of the clamping block 10.

[0033] Furthermore, the mounting bracket 7 is fixed to the positioning seat 2 by the support column. There are three mounting brackets 7, which are located on the outside of the positioning seat 2 where the three sliders 8 are located. The upper end of the mounting bracket 7 has an opening for the rod of the bolt 13 to pass through.

[0034] Furthermore, a rotating handle 14 is provided at the end of the bolt 13 by means of threads. The rotating handle 14 is located on the outside of the mounting bracket 7 and is used to drive the clamping block 10 and the V-block 11 to move on the slide rail 4 via the slider 8. A spring 15 is sleeved on the rod of the bolt 13. One end of the spring 15 abuts against the mounting bracket 7 and the other end abuts against the clamping block 10 and the V-block 11, which is used to limit the rotating handle 14.

[0035] Furthermore, the base frame 1 has an adjustment rod 18 for position adjustment;

[0036] Furthermore, the base frame 1 has a limit stop bar 19 that restricts the movement of the base frame 1.

[0037] Working principle:

[0038] In use, the base frame 1 is adjusted to a suitable position using the adjusting rod 18 and the limiting stop rod 19. During use, the hanging ear body 17 is placed in the V-shaped groove 5 formed by the four frustums 3. At the same time, the rotating handle 14 is rotated, and the rotating handle 14 abuts against the mounting frame 7, causing the bolt 13 to rotate and move. The nut part of the bolt 13 located in the slot of the clamping block 10 drives the two clamping blocks 10 and the slider 8 to move towards the center along the slide 4. At this time, the clamping blocks 10 move along the V-shaped groove 5, and the hanging ear body is held in place by the V-shaped structure of the two clamping blocks 10. The two sides of 17 are clamped to facilitate laser marking. During this process, the spring 15 on the bolt 13 remains compressed, giving the clamping block 10 a force toward the center, thereby driving the rotating handle 14 to always contact the mounting bracket 7 to prevent loosening and ensure effective limiting of the hanging ear body 17. When disassembling, simply pull the rotating handle 14 outward to move the clamping block 10 and the slider 8 to the outside of the slide rail 4, making it easy to remove the hanging ear body 17 and also to limit the next hanging ear body 17 of the same model.

[0039] In another embodiment, the handle body 16 is placed in the slide rail 4 perpendicular to the two clamping blocks 10, with the top of the handle body 16 abutting against the groove of the V-block 11. At the same time, the limiting stud 12 is located at the opening at the front end of the handle body 16. Since the handle body 16 is an arc-shaped structure, the middle part of the handle body 16 rests on the contact strip 6 of the two frustums 3 adjacent to the V-block 11. Rotating the rotating handle 14 causes it to abut against the mounting bracket 7, which in turn drives the bolt 13 to rotate and move. The nut part of the bolt 13 located in the slot of the V-block 11 drives the V-block 11 and the slider 8 to move along the slide rail 4 to adjust the position of the V-block 11 for easy laser marking.
