DETAILED DESCRIPTION

[0016] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with specific embodiments of the present invention and corresponding drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] The technical solutions provided by various embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0018] Reference Figures 1 to 9As shown, an embodiment of the present invention provides an automated positioning device for radiator processing, comprising a workbench 1 and a carrying plate 2, wherein a baffle 11 is longitudinally arranged on the rear side of the workbench 1, the carrying plate 2 is slidably arranged on the front side of the baffle 11 in the vertical direction, and a limit plate 21 extending vertically upward is arranged at the rear end of the carrying plate 2, and side plates 3 are provided at the left and right ends of the carrying plate 2 for moving along the left and right directions thereof, a vertical plate 4 is provided at the front end of the carrying plate 2 for moving along the front and rear directions thereof, and a contact plate 5 elastically connected to the vertical plate 4 is provided on the rear side of the vertical plate 4, the carrying plate 2 and the workbench 1 are elastically connected together by a group of first elastic components 6, and a group of first gravity drive mechanisms 7 are provided under the two side plates 3, and the two groups of first gravity drive mechanisms 7 drive the two side plates 3 to move away from or closer to each other when the carrying plate 2 is lifted or lowered, and a second gravity drive mechanism 9 is provided under the vertical plate 4, and the second gravity drive mechanism 9 drives the vertical plate 4 to move in the direction away from or closer to the baffle 11 when the carrying plate 2 is lifted or lowered.

[0019] The automatic positioning device for radiator processing is used to process the radiator to be processed. During actual processing, the staff first places the radiator to be processed, and it is necessary to ensure that the length direction of the radiator to be processed is distributed along the left and right directions of the supporting plate 2, and at the same time, the radiator to be processed is roughly between the two side plates 3. Then, the supporting plate 2 is affected by the gravity of the radiator to be processed, and the supporting plate 2 will slide downward along the baffle 11. The first elastic component 6 is compressed. In the process of the supporting plate 2 descending, the two side plates 3 can be driven close to each other through the two sets of first gravity driving mechanisms 7. At the same time, under the action of the second gravity driving mechanism 9, the vertical plate 4 can be driven to move in the direction of the limit plate 21. Since the radiator to be processed is located between the two side plates 3 and the vertical plate 4, and the vertical plate 4 is closer to the limit plate 21, the radiator to be processed will first be pushed by the contact plate 5 on the rear side of the vertical plate 4 and abut against the limit plate 21, thereby completing the radiator to be processed. The radiator 2 is positioned in the front and rear directions, and then, affected by the gravity of the radiator to be processed, the supporting plate 2 will continue to drop. Since the vertical plate 4 and the resistance plate 5 are elastically connected, the vertical plate 4 can continue to approach the limit plate 21 while ensuring that the resistance plate 5 is stationary and still rests on the radiator to be processed, and the two side edges will continue to approach, thereby calibrating the position of the radiator to be processed in the left and right directions. Finally, the radiator to be processed will be clamped by the two side plates 3, and the positioning of the radiator to be processed can be completed. The present invention can complete the position correction and positioning of the radiator to be processed by relying solely on the gravity of the radiator to be processed without the need for a driving source, thereby ensuring the processing position accuracy of the radiator to be processed. At the same time, by setting the resistance plate 5 and the vertical plate 4 to be elastically connected, the resistance plate 5 and the two side plates 3 can realize adaptive clamping and positioning of radiators to be processed of various models and lengths within a certain range.

[0020] Specifically, the left and right ends of the carrying plate 2 are each provided with a first slide groove 22 extending in the left and right direction thereof, and the bottoms of the two side plates 3 are each provided with a first slider 31, and the two first sliders 31 are respectively slidably disposed in the two first slide grooves 22, and the lower end of each first slider 31 is fixedly connected to a first riser 32, and the two first risers 32 are both located below the carrying plate 2; The front end of the carrier plate 2 is provided with a second chute 23 extending in the front-to-back direction thereof, and the bottom of the vertical plate 4 is provided with a second slider 41, which is slidably disposed in the second chute 23. The lower end of the second slider 41 is fixedly connected to a second vertical plate 42, and the second vertical plate 42 is located below the carrier plate 2; The second gravity drive mechanism 9 has the same internal structure and principle as the two sets of first gravity drive mechanisms 7; The first gravity-driven mechanism 7 includes a first slide rail 71, a first connecting rod 72, a first hinge seat 73, and a second hinge seat 74. The first hinge seat 73 is mounted on the actuator of the first slide rail 71. The first slide rail 71 is provided on the workbench 1 to drive the first hinge seat 73 to move left and right along the workbench 1. The second hinge seat 74 is mounted on the lower end of the carrying plate 2. The two ends of the first connecting rod 72 are hinged to the first hinge seat 73 and the second hinge seat 74, respectively. A linkage assembly 8 is provided between the first hinge seat 73 and the side panel 3 . When the first slide rail 71 drives the first hinge seat 73 to move, the linkage assembly 8 can drive the side panel 3 to move in the opposite direction along the first slide slot 22 .

[0021] By providing the first slide groove 22 on the carrying plate 2, the technical effect of the two side panels 3 sliding along the left and right directions of the carrying plate 2 can be achieved. By providing the second slide groove 23 on the carrying plate 2, the technical effect of the vertical plate 4 sliding along the front and rear directions of the carrying plate 2 can be achieved. Since the two ends of the first connecting rod 72 are respectively hinged to the first hinge seat 73 and the second hinge seat 74, in the initial state, the first connecting rod 72 is tilted inward and upward from the direction of the first hinge seat 73 to point to the second hinge seat 74. After the staff places the radiator to be processed on the carrying plate 2, the downward movement of the carrying plate 2 will drive the first hinge seat 73 on the corresponding first slide rail 7 under the action of the first connecting rod 72. 1, and under the corresponding linkage assembly 8, the side plate 3 will be driven to move along the first slide groove 22 toward the center of the carrying plate 2. Therefore, under the action of the two groups of first gravity drive mechanisms 7, as the carrying plate 2 descends, the two side plates 3 can be brought close to each other, and finally the radiator to be processed can be clamped in the middle by the two side plates 3 to complete the position correction and left and right positioning of the radiator to be processed. With the same principle of the first gravity drive, as the carrying plate 2 descends, the vertical plate 4 and the contact plate 5 can be driven to move toward the limit plate 21 together. Under the pushing action of the contact plate 5, the radiator to be processed can be pressed against the limit plate 21, thereby realizing the positioning of the radiator to be processed in the front and back directions.

[0022] Specifically, the linkage assembly 8 includes a second link 81, a third link 82, a third hinge seat 83, a mounting block 84 and a second elastic assembly 85. The mounting block 84 is fixedly arranged on one side of the first slide rail 71 close to the center of the workbench 1, and the third hinge seat 83 is mounted on the mounting block 84. One end of the second link 81 is hinged on the first hinge seat 73, and the other end of the second link 81 is tilted upward to contact the outer side of the first vertical plate 32. One end of the third link 82 is hinged on the third hinge seat 83, and the other end of the third link 82 is tilted upward and hinged at the center of the second link 81. The second elastic assembly 85 is arranged on the inner side of the first vertical plate 32 for elastically supporting the first vertical plate 32. A side surface of the top of the second connecting rod 81 is provided with a transversely extending rotating shaft 811 . An annular sleeve 86 is rotatably provided on the rotating shaft 811 . The annular sleeve 86 abuts against the outer side of the first vertical plate 32 .

[0023] like Figure 5 and Figure 6As shown, in the initial state, the second connecting rod 81 is tilted to the upper right and contacts the first vertical plate 32. At this time, the internal angle between the second connecting rod 81 and the horizontal plane is close to ninety degrees. When the supporting plate 2 moves downward under the gravity of the radiator to be processed, the first hinge seat 73 will move to the left along the first slide rail 71. As a result, under the pulling action of the third connecting rod 82 on the second connecting rod 81, the second connecting rod 81 can be flipped to the right around the first hinge seat 73, thereby causing the internal angle between the second connecting rod 81 and the horizontal plane to gradually decrease, and the upper end of the second connecting rod 81 will push the corresponding first vertical plate 32 to move toward the center of the supporting plate 2, thereby completing the movement of the side plate 3 along the first slide groove 22 toward the center of the supporting plate 2. On the contrary, when the processing of the radiator to be processed is completed, the staff directly pushes the supporting plate 2 slightly upward by hand, and then removes the radiator to be processed from the supporting plate The plate 2 is removed from the plate 2, so that the supporting plate 2 can be restored to its original state under the action of the first elastic component 6. During this process, the first connecting rod 72, the second connecting rod 81 and the third connecting rod 82 are also restored to their original states. Then, under the elastic action of the second elastic component 85, the first vertical plate 32 can also move and abut against the top end of the second connecting rod 81; an annular sleeve 86 is provided by rotating at the top end of the second connecting rod 81, and the annular sleeve 86 abuts against the first vertical plate 32, so that the annular sleeve 86 can push the first vertical plate 32 to move while reducing the wear between the second connecting rod 81 and the first vertical plate 32. By providing the second elastic component 85, it can be ensured that the first vertical plate 32 always abuts against the annular sleeve 86, thereby realizing the self-resetting of the side plate 3. Similarly, the second elastic component 85 on the second gravity drive mechanism 9 can realize the self-resetting of the vertical plate 4.

[0024] Specifically, the second elastic component 85 includes a connecting plate 851, a second spring 852 and a second guide rod 853. The connecting plate 851 is longitudinally mounted on the supporting plate 2 and is located on the inner side of the first vertical plate 32. The second guide rod 853 is mounted on the inner end of the first vertical plate 32. The length direction of the second guide rod 853 is consistent with the length direction of the first sliding groove 22. The connecting plate 851 is provided with a second guide hole 8511. The second guide rod 853 is slidably disposed in the second guide hole 8511. A second circular plate 854 is mounted on the inner end of the second guide rod 853. The second circular plate 854 is located on the inner side of the connecting plate 851. The second spring 852 is sleeved on the second guide rod 853. The second spring 852 is located between the first vertical plate 32 and the connecting plate 851. Two first guide rods 51 extending along the front and rear directions of the supporting plate 2 are provided on the front side of the contact plate 5, and two first guide holes 43 are provided on the vertical plate 4. The two first guide rods 51 are respectively slidably set in the two first guide holes 43, and the front ends of the two first guide rods 51 are installed with first circular plates 52, each of the first circular plates 52 is located on the front side of the vertical plate 4, and each first guide rod 51 is sleeved with a first spring 53, and the two first springs 53 are both located between the vertical plate 4 and the contact plate 5.

[0025] When the first vertical plate 32 moves toward the center of the supporting plate 2, the second guide rod 853 slides along the second guide hole 8511, and the second spring 852 is compressed. Under the elastic action of the second spring 852, the second vertical plate 42 will always contact the annular sleeve 86. Similarly, when the first vertical plate 32 moves away from the center of the supporting plate 2, under the elastic action of the second spring 852, the second vertical rod still always contacts the annular sleeve 86. Therefore, after the annular sleeve 86 is restored to its original state, the side plate 3 can be reset by itself under the action of the second spring 852. When the vertical plate 4 approaches the limit plate 21 under the action of the second gravity drive mechanism 9 When the radiator 2 is moved in the direction of rotation, the contact plate 5 first contacts the radiator to be processed, and then the radiator to be processed is pressed against the limit plate 21 under the pushing action of the contact plate 5, thereby completing the positioning of the contact plate 5 in the front and rear directions. Then, under the influence of the gravity of the radiator to be processed, the supporting plate 2 continues to descend, so that the two side plates 3 will approach each other, and finally the two side plates 3 correct the left and right positions of the radiator to be processed, and finally the two side plates 3 clamp the radiator to be processed in the middle. In this process, under the action of the first spring 53, the vertical plate 4 continues to move in the direction of the limit plate 21, and the contact plate 5 can remain in contact with the radiator to be processed and remain stable.

[0026] Specifically, a longitudinally extending second guide rail 12 is installed on both the left and right sides of the baffle 11, and a third slider 24 is connected to both the left and right sides of the carrying plate 2. The two third sliders 24 are respectively slidably arranged on the two second guide rails 12; The first elastic component 6 includes two cylinders 61, both of which are longitudinally installed on the workbench 1 and are respectively located on the left and right sides of the baffle 11. A slide 62 is slidably arranged inside each cylinder 61, and a connecting rod 63 is longitudinally arranged on the top of the two slides 62. The two connecting rods 63 are respectively fixedly installed on the two third sliders 24. A third spring 64 is coaxially arranged in the two cylinders 61, and each third spring 64 is located below the corresponding slide 62.

[0027] By installing a longitudinally extending second guide rail 12 on both sides of the baffle 11 and correspondingly providing a third slider 24 on the carrier plate 2, the two third sliders 24 are respectively slidably set on the two second guide rails 12, thereby achieving the technical effect of the carrier plate 2 being slidably set on the baffle 11; when the carrier plate 2 is lifted or lowered, the two slides 62 will be respectively slidably set in the two cylinders 61, thereby under the action of the two third springs 64, elastic support for the carrier plate 2 can be achieved, and the elastic support of the third spring 64 can enable the staff to place the radiator to be processed on the carrier plate 2, and the gravity of the radiator to be processed will cause the carrier plate 2 to drop, and when the staff removes the radiator to be processed, the carrier plate 2 will rise and return to its original position under the elastic force of the third spring 64.

[0028] The foregoing is merely an embodiment of the present invention and is not intended to limit the present invention. It will be apparent to those skilled in the art that various modifications and variations of the present invention are possible.
