Description

Technical Field

[0001] This invention relates to the field of welding, and more particularly to a fixing device for machining irregularly shaped automotive hinges. Background Technology

[0002] In the automotive body manufacturing industry, the processing requirements for irregularly shaped hinges are very strict. Therefore, when welding irregularly shaped automotive hinges, in order to improve the processing effect, a fixing device is usually needed to fix the welding of the irregularly shaped automotive hinges.

[0003] A search revealed Chinese patent application CN117399767A, which discloses a fixing device for processing irregularly shaped automotive hinges. This device relates to the field of automotive manufacturing technology and includes an assembly table and an electric telescopic table. The electric telescopic table is fixedly connected to the upper surface of the assembly table. A welding assembly is provided at the output end of the top of the electric telescopic table. A fixing clamping assembly is provided on the upper surface of the assembly table and on one side of the electric telescopic table. The welding assembly includes a base platform and a universal ball joint. The base platform is fixedly connected to the output end of the top of the electric telescopic table, and the universal ball joint is movably connected to the top of the base platform. By adjusting the direction of the universal ball joint and the universal plate, the welding surface of the projection weld nut placed on the top of the welding table is made to coincide with the hinge. This avoids the thread deformation caused by uneven force during welding of the projection weld nut due to uneven force caused by the hinge and the welding surface of the projection weld nut not being on the same plane when the hinge is manually leveled, thus improving operational accuracy and ensuring the engineering quality and efficiency of hinge processing.

[0004] When welding and fixing irregularly shaped car hinges, the unusual shape of the hinges can lead to poor fixing effect, causing them to fall off during welding and affecting the welding process. Summary of the Invention

One side of the pad is hinged to one of the push plates. The two push plates are arranged in a V-shape. The other ends of the push plates are hinged to the two push blocks. Slots are provided on opposite sides of the fixing clamp. A second spring is bolted to the inner wall of one side of each slot. The other end of the second spring is fixedly connected to the clamping plate. A first spring is bolted to one side of the pad and to the fixing clamp. Both sides of the plate have connection ports. The push block is slidably connected to the inner wall of one side of the connection port. A push rod is connected to one side of the push block and one side of the swing plate through a hinge. One side of the support frame is connected to the fixed clamp through bolts. The two opposite sides of the support frame are rotatably connected to the swing plate through bearings. A pull-out opening is opened through one side of the slot. A top rod is slidably connected to the inner wall of the pull-out opening. One end of the top rod contacts the clamp plate, and the other end of the top rod is connected to the swing plate through a hinge. Multiple anti-slip grooves are opened on the opposite sides of the two clamp plates.

[0009] Preferably, each of the fixing clamps has a sliding groove on its opposite side, and the inner walls of the two sliding grooves are slidably connected to sliders, and the two sliders are connected to the pad by bolts.

[0010] Preferably, an adjustment mechanism is provided between the translation mechanism and the support base, and the bottom of the adjustment mechanism is fixedly connected to the translation mechanism.

[0011] Preferably, the adjustment mechanism includes an adjustment seat, a second screw, two adjustment blocks, two top plates, and a connecting frame. The bottom of the adjustment seat is bolted to the translation block and the guide block. Adjustment grooves are provided on both sides of the top of the adjustment seat. One side of each adjustment groove is rotatably connected to both ends of the second screw via bearings. Adjustment blocks are slidably connected to the inner walls of each adjustment groove. Threaded openings are provided on one side of each adjustment block. The two threaded openings are threaded to the second screw.

A support rod is bolted to one side of the positioning block, and the bottom of the support rod is fixedly connected to the top of the adjustment base.

[0014] The beneficial effects of this invention are as follows:

[0015] 1. This invention, through its translation and fixing mechanisms, fixes an irregularly shaped automotive hinge during welding. One end of the hinge is inserted into one of the fixing clamps and contacts a pad. The motor is then activated, causing the translation mechanism to move the two clamps towards each other. The other end of the hinge is then fixed inside the other clamp and contacts the pad. As the translation mechanism continues to move the clamps, the hinge presses against the pad. Under this pressure, the pad moves to one side, and the two push plates unfold to the sides. During this unfolding process, the two push plates push... The push block slides to one side, causing the push rod to deflect one end of the swing plate under the action of the push block. The other end of the swing plate will deflect in the opposite direction. At this time, the deflected end of the swing plate will push the push rod to one side, so that the push rod will push the clamping plate out of the groove. This allows the clamping plate to press and fix one end of the irregular-shaped car hinge, thereby improving the fixing effect of the irregular-shaped car hinge and improving the welding effect of the irregular-shaped car hinge. This prevents the irregular-shaped car hinge from having a poor fixing effect during welding due to its irregular shape, which could cause the irregular-shaped car hinge to fall off during welding and affect the welding of the irregular-shaped car hinge.

[0016] 2. The present invention, through its adjustable mechanism, addresses the unusual structure of irregularly shaped car hinges during welding. The adjustable mechanism allows for the adjustment of the height of the two fixing clamps based on the height difference between the two ends of the hinge, facilitating the fixation of the hinge and improving the welding effect. This prevents poor fixation due to height differences at both ends of the hinge, which could negatively impact the welding process. Attached Figure Description

[0025] Example 1: Refer to Figure 1-5A fixing device for processing irregularly shaped automotive hinges includes a fixing base 1. A translation mechanism 3 is provided on the top of the fixing base 1, and the translation mechanism 3 consists of a motor 8 and a first screw 10. Translation grooves 9 are formed on both sides of the top of the fixing base 1, and one side of each translation groove 9 is rotatably connected to both ends of the first screw 10 via bearings. Translation blocks 11 are slidably connected inside each of the two translation grooves 9, and threaded holes are formed on one side of each of the two translation blocks 11. The two threaded holes are threadedly connected to the first screw 10. One side of the motor 8 is fixed to the fixing base 1. The motor 8 is connected to the first screw 10 at one end. The tops of the two translation blocks 11 are connected to the support base 12 by bolts. The tops of the two support bases 12 are connected to the fixing clips 4 by bolts. The fixing mechanism 5 is set inside the two fixing clips 4 to improve the fixing effect of the irregular car hinge, so as to improve the welding effect of the irregular car hinge and prevent the irregular car hinge from falling off during welding due to its irregular shape, thus affecting the welding of the irregular car hinge.

[0026] Based on the above, guide grooves 6 are provided on both sides of the top of the fixed base 1, and the two guide grooves 6 are symmetrically distributed on both sides of the translation groove 9. The inner wall of the guide groove 6 is slidably connected with a guide block 7, and the top of the guide block 7 is connected to the bottom of the support base 12 by bolts.

[0027] Based on the above, the fixing mechanism 5 includes two clamping plates 26, a pad 16, two push plates 18, two push blocks 19, two support frames 23, and two swing plates 22. One side of the pad 16 is connected to the two push plates 18 by a hinge. The two push plates 18 are arranged in a V-shape. The other end of the two push plates 18 is connected to the two push blocks 19 by a hinge. The fixing clamp 4 has slots 15 on both opposite sides. A second spring 25 is bolted to the inner wall of one side of the slot 15. The other end of the second spring 25 is fixedly connected to the clamping plate 26. A first spring 20 is bolted to one side of the pad 16 and the fixing clamp 4. The fixing clamp 4 has slots 15 on both opposite sides. A connection port 14 is provided, and a push block 19 is slidably connected to the inner wall of one side of the connection port 14. A push rod 21 is hinged to one side of the push block 19 and one side of the swing plate 22. One side of the support frame 23 is bolted to the fixing clamp 4. The opposite sides of the support frame 23 are rotatably connected to the swing plate 22 through bearings. A pull-out opening is provided through one side of the inner wall of the slot 15. A push rod 24 is slidably connected to the inner wall of the pull-out opening. One end of the push rod 24 contacts the clamping plate 26, and the other end of the push rod 24 is hinged to the swing plate 22. Multiple anti-slip grooves are provided on the opposite sides of the two clamping plates 26. When fixing the welding of the irregularly shaped car hinge... One end of the irregularly shaped car hinge is inserted into one of the fixing clamps 4 and contacts the pad 16. At this time, the motor 8 is started, causing the translation mechanism 3 to move the two fixing clamps 4 towards each other. The other end of the irregularly shaped car hinge is then fixed inside the other fixing clamp 4 and contacts the pad 16. As the translation mechanism 3 continues to move the fixing clamps 4, one end of the irregularly shaped car hinge presses against the pad 16. The pad 16, after being pressed, moves to one side, and the two push plates 18 unfold to both sides under pressure. When the two push plates 18 unfold, they push the push block 19 to slide to one side, thus causing the push rod 21 to... Under the action of the push block 19, one end of the swing plate 22 is deflected, while the other end of the swing plate 22 is deflected in the opposite direction. At this time, the deflected end of the swing plate 22 pushes the push rod 24 to one side, so that the push rod 24 pushes the clamping plate 26 out of the groove 15, so that the clamping plate 26 can squeeze and fix one end of the irregular car hinge, thereby improving the fixing effect of the irregular car hinge, improving the welding effect of the irregular car hinge, and preventing the irregular car hinge from falling off during welding due to its irregular shape, which would affect the welding of the irregular car hinge.

[0028] Based on the above, each of the opposite sides of the fixing clamp 4 is provided with a sliding groove 13, and the inner walls of the two sliding grooves 13 are slidably connected with sliders 17, and the two sliders 17 are connected to the pad 16 by bolts.

[0029] Example 2: Refer to Figure 1-7 A fixing device for processing irregularly shaped automotive hinges, compared with Embodiment 1, has an adjustment mechanism 2 provided between the translation mechanism 3 and the support base 12, and the bottom of the adjustment mechanism 2 is fixedly connected to the translation mechanism 3.

[0030] Based on the above, the adjustment mechanism 2 includes an adjustment seat 28, a second screw 35, two adjustment blocks 31, two top plates 32, and a connecting frame 34. The bottom of the adjustment seat 28 is bolted to the translation block 11 and the guide block 7. Adjustment grooves 30 are provided on both sides of the top of the adjustment seat 28. One side of each adjustment groove 30 is rotatably connected to both ends of the second screw 35 via bearings. Adjustment blocks 31 are slidably connected to the inner walls of each adjustment groove 30. Threaded openings are provided on one side of each adjustment block 31, and these threaded openings are threaded to the second screw 35. The tops of the two adjustment blocks 31 are hinged to the two top plates 32. The connecting frame 34 is connected to the two top plates 32 via... A rotating connection is formed through the bearing. The top of the connecting frame 34 is connected to the bottom of the support base 12 by bolts. One end of the second screw 35 extends to one side of the adjusting seat 28, and one end of the second screw 35 is connected to the turntable 36 by bolts. When welding the irregularly shaped car hinge, due to the unusual structure of the irregularly shaped car hinge, the height of the two fixing clips 4 can be adjusted according to the height difference at both ends of the irregularly shaped car hinge by the adjusting mechanism 3, so as to fix the irregularly shaped car hinge, thereby improving the welding effect of the irregularly shaped car hinge and preventing the irregularly shaped car hinge from being poorly fixed due to the different heights at both ends of the irregularly shaped car hinge, which would affect the welding of the irregularly shaped car hinge.

[0031] Based on the above, positioning grooves 27 are provided on both sides of the support base 12, and positioning blocks 33 are slidably connected to the inner wall of the positioning grooves 27. A support rod 29 is bolted to one side of the positioning block 33, and the bottom of the support rod 29 is fixedly connected to the top of the adjusting base 28.

[0032] In summary, using the above-mentioned technical solution of the present invention: when fixing the welding of the irregularly shaped car hinge, one end of the irregularly shaped car hinge is inserted into the interior of one of the fixing clamps 4 and contacts the pad 16. At this time, the motor 8 is started, so that the translation mechanism 3 drives the two fixing clamps 4 to move towards each other. At this time, the other end of the irregularly shaped car hinge will be fixed inside the other fixing clamp 4 and contact the pad 16. As the translation mechanism 3 drives the fixing clamp 4 to continue to move, one end of the irregularly shaped car hinge will squeeze the pad 16. After being squeezed, the pad 16 will move to one side, and the two push plates 18 will unfold to both sides under the pressure. At this time, when the two push plates 18 unfold, they will push the push block 19 to slide to one side, so that the push rod 21 drives one end of the swing plate 22 to deflect under the action of the push block 19, and the other end of the swing plate 22 will deflect in the opposite direction. At this time, the reverse-deflected end of the swing plate 22 will... The push rod 24 is moved to one side, causing it to push the clamping plate 26 out of the slot 15. This allows the clamping plate 26 to press and fix one end of the irregularly shaped car hinge, improving the fixing effect and welding performance. This prevents the irregularly shaped car hinge from detaching during welding due to its unusual shape, which could negatively impact the welding process. Because of the unusual structure of the car hinge, the adjusting mechanism 3 can adjust the height of the two fixing clamps 4 according to the height difference at both ends of the hinge. This helps to fix the hinge and improve the welding effect, preventing poor fixing due to height differences at both ends, which could negatively affect the welding process.

[0033] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
