Detailed Implementation

[0026] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0027] refer to Figure 1 and Figure 2A hinge welding positioning fixture includes a welding table 1. Two protrusions 2 are provided on the end face of the welding table 1. Two clamping blocks 3 are slidably provided on one side of each of the two protrusions 2. Slide grooves 4 are provided on both sides of the welding table 1. Limiting slide rails 5 are provided on one side of each of the two slide grooves 4. Toothed blocks 6 are provided on the surface of each of the two limiting slide rails 5. Sliding blocks 7 are slidably provided on the outside of each of the two toothed blocks 6. Baffles 8 are provided on the surface of each sliding block 7. A locking block 9 that can engage with the toothed blocks 6 is slidably provided inside each sliding block 7.

[0028] In this design, a hinge body 23 for operation demonstration is provided on the end face of the welding table 1, and blade plates 24 for welding demonstration are provided on both sides of the hinge body 23. Two protrusions 2 on the end face of the welding table 1 are located at both ends of the welding table 1 and are used to connect clamping springs 10. After being compressed, the clamping springs 10 will recover due to elastic potential energy and push the sleeve 11 in the opposite direction to provide power to the clamping block 3. Multiple toothed blocks 6 on one side of the limiting slide rail 5 are only provided on the upper part of the side wall of the limiting slide rail 5. This arrangement allows the locking block 9 to move downward and then disengage from the toothed groove formed by the toothed block 6, so that the sliding block 7 can slide on the surface of the limiting slide rail 5, thereby driving the baffle 8 to move. This allows the baffle 8 to be adaptively adjusted according to the blade plate 24, thereby improving the positioning effect of the baffle 8 on the blade plate 24.

[0029] refer to Figure 3 and Figure 4 Each of the two protrusions 2 is provided with a clamping spring 10 on one side, and each of the two clamping springs 10 is provided with a sleeve 11 on the outside. The two clamping springs 10 are fixedly connected to the inner wall of the sleeve 11 respectively, and each sleeve 11 is fixedly connected to the two clamping blocks 3 respectively.

[0030] In this design, two clamping springs 10 and two sleeves 11 are grouped together and respectively set on one side of the two protrusions 2. When clamping the hinge body 23, it is only necessary to first press one end of the hinge body 23 against the outer wall of one of the sleeves 11 and squeeze the sleeve 11. The sleeve 11 squeezes the clamping spring 10 and moves backward. Then, the hinge body 23 is placed in the arc-shaped placement groove 20. At this time, the compressed clamping spring 10 recovers its elastic potential energy and pushes the sleeve 11 to clamp the hinge body 23. The operation is simple and convenient and can effectively improve work efficiency.

[0031] refer to Figure 1 and Figure 2 Each of the two sleeves 11 has a positioning block 12 on one side, and the two positioning blocks 12 are set in opposite directions.

[0032] In this design, the positioning blocks 12 are staggered. This arrangement can block one side of the outer circular surface of the hinge body 23 while welding is performed on the other side, facilitating simultaneous welding of the two blades 24 without adjusting the orientation of the hinge body 23. The hinge body 23 is subjected to the thrust of the welding torch during welding. This arrangement also prevents the hinge body 23 from detaching from the arc-shaped placement groove 20. The top of the positioning block 12 is curved, which allows the positioning block 12 to better fit the outer surface of the hinge body 23 and prevents the hinge body 23 from sliding upwards during welding, thereby improving the positioning effect.

[0033] refer to Figure 2 The welding table 1 has an installation groove 13 on its end face. The installation groove 13 has a limit groove 14 inside. The limit groove 14 has a limit block 15 slidingly installed inside. The limit block 15 is fixedly connected to the bottom end face of the clamping block 3.

[0034] In this design, both the clamping block 3 and the sleeve 11 are located inside the mounting groove 13. This arrangement allows the clamping block 3 and the sleeve 11 to be lower than the plane of the welding table 1, making it easier for the clamping block 3 and the sleeve 11 to contact the end faces of the blade plate 24 and the hinge body 23, thereby improving the positioning effect. The limiting groove 14 and the limiting block 15 can restrict the sliding direction of the clamping block 3, preventing the clamping block 3 from tilting during movement and ensuring the normal use of the device.

[0035] refer to Figure 1 and Figure 2 Each of the multiple clamping blocks 3 has a rubber block 16 on one side.

[0036] In this scheme, when the clamping block 3 contacts the blade plate 24, it will first contact the rubber block 16. The rubber block 16 can increase the friction between the clamping block 3 and the blade plate 24, thereby improving the positioning effect.

[0037] refer to Figure 5 , Figure 6 , Figure 7 and Figure 8 A vertical plate 17 is provided on one side of the card block 9. The vertical plate 17 is slidably connected to the inside of the sliding block 7. A horizontal plate 18 is provided inside each of the two sliding blocks 7. Multiple limiting springs 19 are provided on the end faces of the two horizontal plates 18. The other ends of the multiple limiting springs 19 are respectively fixedly connected to the bottom of the card block 9.

[0038] In this design, the locking block 9 is connected to the bottom of the vertical plate 17. When the vertical plate 17 moves upward, it will drive the locking block 9 to move upward, so that the locking block 9 enters the tooth groove formed by the toothed block 6, thereby achieving the effect of limiting the sliding block 7. The vertical plate 17 can slide inside the sliding block 7 and extend upward from inside the sliding block 7. This setting can be achieved by pressing the vertical plate 17 to drive the locking block 9 to move downward, so that the locking block 9 disengages from the tooth groove formed by the toothed block 6, thereby achieving the effect of releasing the limit, thus facilitating the movement of the sliding block 7, and enabling the baffle 8 at the top of the sliding block 7 to adaptively adjust the position of the blade 24, so that the baffle 8 can adjust the positioning distance according to the blade 24 of different specifications.

[0039] refer to Figure 1 and Figure 2 An arc-shaped placement groove 20 is provided on the end face of the welding table 1, and a material picking groove 21 is provided in the middle section of the arc-shaped placement groove 20.

[0040] In this design, the width of the opening of the material trough 21 is greater than that of the arc-shaped placement trough 20, and the diameter of the middle section of the material trough 21 is greater than that of the two ends, forming a trough that is narrow at both ends and wide in the middle. This design makes it easier to remove the hinge body 23 and improves the efficiency of picking and placing.

[0041] refer to Figure 5 and Figure 6 Both baffles 8 have protrusions 22 on their end faces, and the two protrusions 22 are set in opposite directions.

[0042] In this design, the protrusion 22 can increase the contact area between the baffle 8 and the blade 24, making it easier for the baffle 8 to better clamp the blade 24.

[0043] In use, the operator needs to first contact one end of the hinge body 23 with one of the sleeves 11 and squeeze the sleeve 11. After the sleeve 11 is pushed, it squeezes the clamping spring 10 inside and moves backward. At this time, the distance between the two sleeves 11 increases. Then, the hinge body 23 is placed in the arc-shaped placement groove 20. The clamping spring 10, which was squeezed, recovers its elastic potential energy and pushes the sleeve 11, causing the sleeve 11 to move towards the other sleeve 11, thus forming a clamping and positioning effect on the hinge body 23 between the two sleeves 11.

[0044] Then, place the blades 24 to be welded on both sides of the hinge body 23, and press the vertical plate 17, causing the vertical plate 17 to move the bottom locking block 9 downward. When the vertical plate 17 moves downward, it will squeeze the bottom limiting spring 19, causing the limiting spring 19 to shorten. When moving, the locking block 9 will disengage from the toothed groove formed by the toothed blocks 6. After the locking block 9 disengages, press the vertical plate 17 and move the sliding block 7, so that the baffle 8 on the sliding block 7 abuts against one side of the blade 24. After the abutment is completed, release the vertical plate 17. At this time, the limiting spring 19 recovers due to elastic potential energy and pushes the vertical plate 17 to move upward. When the vertical plate 17 moves, it drives the locking block 9 to move upward. The locking block 9 moves upward and enters the toothed groove formed by the toothed blocks 6, thereby fixing the position of the sliding block 7. The baffle 8 on the top of the sliding block 7 positions the blade 24. Then, the blade 24 and the hinge body 23 are welded together by the welding device.
