[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1 This utility model provides a technical solution: a stable and adjustable positioning fixture, including: a base 1 and a clamp 4, an arc-shaped groove 2 is provided on the top of the base 1, a sliding block 3 is slidably connected to the top of the arc-shaped groove 2, and the clamp 4 is installed on the top of the sliding block 3.

[0026] exist Figures 2-4 In the middle, an arc-shaped rack 5 is installed on the inner wall of the arc-shaped groove 2. A gear 6 is meshed with one side of the arc-shaped rack 5. A connecting shaft 7 is connected through the middle of the gear 6. The connecting shaft 7 is connected to the bottom of the sliding block 3 through a bearing.

[0027] The stabilizing positioning fixture allows the sliding block 3 to slide along the arc groove 2 via the connecting shaft 7 at the bottom of the sliding block 3 and the gear 6. At the same time, when the gear 6 slides along the arc groove 2, it is meshed by the arc rack 5, which causes the gear 6 to rotate.

[0028] exist Figure 3 In the middle, the gear 6 has a first locking block 8 on both sides, and a connecting post 9 is installed through the sliding block 3 at the top of the first locking block 8. The sliding block 3 has slots on both sides, and a pressure block 10 is installed through the slot on one side of the connecting post 9.

[0029] The positioning fixture for this stabilization adjustment can limit the gear 6 by the first locking blocks 8 on both sides of the gear 6, so that the gear 6 cannot rotate. When the gear 6 cannot rotate, it is affected by the arc rack 5 in the arc groove 2, which also prevents the sliding block 3 from sliding along the arc groove 2.

[0030] exist Figure 3 and Figure 7In the middle, a movable spring 11 is provided between the outer side of the connecting column 9 and the sliding block 3, and the end of the connecting column 9 near the pressure block 10 has an inclined structure.

[0031] The stabilizing and adjusting positioning fixture presses the pressure block 10 into the sliding block 3. Since the end of the connecting column 9 near the pressure block 10 is a sloping structure, the pressure block 10 will press the connecting column 9 downward, causing the movable spring 11 to be in a compressed state. At the same time, the pressure block 10 drives the first locking block 8 at the bottom to move downward, causing the first locking block 8 to separate from the gear 6. At this time, the gear 6 can rotate normally, and the sliding block 3 can slide along the arc groove 2. Conversely, when the pressure block 10 is released, the connecting column 9 will drive the first locking block 8 to move upward through the movable spring 11, thereby limiting the gear 6.

[0032] exist Figure 2 In the middle of the base 1, there is a slag discharge port 12. A fixed scraper 13 is installed on the inner wall of the slag discharge port 12. Baffles 14 are installed on both sides of the slag discharge port 12 through the base 1.

[0033] The stabilizing and adjusting positioning fixture can block the slag discharge port 12 by sliding the baffle 14 onto the slag discharge port 12, thereby facilitating the placement of parts.

[0034] exist Figure 2 and Figure 5 In the middle, a fixing block 15 is installed on one side of the baffle 14. A groove is opened in the middle of the fixing block 15. A second locking block 16 is slidably arranged at the bottom of the groove. A pull rod 17 is connected through the groove of the fixing block 15 on one side of the second locking block 16. A telescopic spring 18 is connected between the pull rod 17 and the fixing block 15. A limit block 19 is sleeved on the bottom of the second locking block 16.

[0035] The stabilizing and adjusting positioning fixture moves the second locking block 16 by pulling the pull rod 17 towards one side of the fixed block 15. The second locking block 16 then aligns with the slot on one side of the limiting block 19, allowing the baffle 14 to be pushed into the slag discharge port 12. When the baffle 14 reaches the slag discharge port 12, the second locking block 16 moves into the limiting block 19. Then, the pull rod 17 is released, and the pull rod 17 resets the second locking block 16 via the telescopic spring 18, causing the second locking block 16 to engage with the slot of the limiting block 19. Because the second locking block 16 is misaligned with the slot of the limiting block 19, the baffle 14 can be limited and fixed.

[0036] exist Figure 5 and Figure 6 In the middle, a reset spring 20 is connected between the baffle 14 and the slag discharge port 12, and two sets of baffle 14 are symmetrically installed about the center line of the slag discharge port 12.

[0037] The positioning fixture for this stable adjustment, conversely, by pulling the pull rod 17 in the opposite direction, causes the pull rod 17 to drive the second locking block 16 to align with the slot of the limiting block 19. Without the second locking block 16 and the limiting block 19 limiting the baffle 14, the baffle 14 can be ejected to the outside of the slag discharge port 12 by the reset action of the reset spring 20. At the same time, when the baffle 14 moves, it will hang the waste residue on the slag discharge port 12 down through the fixed scraper 13, thereby facilitating the collection of waste residue.

[0038] exist Figure 2 In the middle, a collection box 21 is provided at the bottom of the slag discharge port 12, and the collection box 21 is slidably connected to the bottom of the slag discharge port 12.

[0039] The positioning fixture that stabilizes the position allows the waste residue hanging off the scraper to fall into the collection box 21 at the bottom of the slag discharge port 12. At this point, you can simply slide the collection box 21 out from the bottom of the slag discharge port 12 to collect and clean the waste residue.

[0040] In summary, when using this stabilizing and adjusting positioning fixture, the parts to be processed can be placed on the base 1 according to the usage requirements. Then, the position of the fixture 4 can be adjusted by the sliding block 3. At this time, the fixture 4 can be rotated to clamp the workpiece. The fixture 4 is mainly composed of a screw, a positioning block, a clamping block, and a guide rod. Therefore, rotating the screw can make the clamping block clamp the workpiece, thereby facilitating subsequent processing of the workpiece. This is the characteristic of the use of this stabilizing and adjusting positioning fixture. The contents not described in detail in this description belong to the prior art known to those skilled in the art.

[0041] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
