Description

Technical Field

[0001] The utility model belongs to the technical field of automobile joint assembly, and particularly relates to a turnover mechanism. Background Art

[0002] With the development of the new energy industry, the performance requirements of new energy batteries are getting higher and higher, and the safety requirements are also increasing. Existing new energy lithium batteries generally self-ignite or explode when the battery cell is overheated or short-circuited. At a certain high temperature, a self-catalytic reaction occurs, resulting in combustion and even explosion. Therefore, the cooling system of new energy batteries is particularly important in actual use.

[0003] like Figure 1 As shown, it is a schematic diagram of the structure of the vehicle end bracket 37. The vehicle end bracket 37 has vehicle end bracket holes 38 at the four corners, which play a role of limiting when assembling the vehicle end bracket 37. There are two groups of vehicle end connecting bodies 39, which are fixed on the vehicle end bracket 37 and are used to cover the vehicle end protection pads 40.

[0004] like Figure 2 As shown in FIG. 1 , it is a schematic diagram of the structure of the vehicle end protection pad 40. The vehicle end protection pad 40 is a flexible pad, and a pad hole 41 is opened on the vehicle end protection pad 40. The diameter of the pad hole 41 is smaller than the diameter of the vehicle end connection body 39. When assembling, the vehicle end protection pad 40 is sleeved on the vehicle end connection body 39. Figure 3 As shown, both sides of the vehicle end bracket 37 are covered with vehicle end protection pads 40. After the vehicle end protection pads 40 are assembled, cover plates are fixed on both sides of the vehicle end bracket 37 by screw fastening to cover the vehicle end protection pads 40.

[0005] After the vehicle end is assembled, it is plugged into the package end of the car connector and used in the cooling system of new energy vehicles (the package end is connected to the new energy battery, the vehicle end is connected to the car's drive device, and coolant is passed through the package end and the vehicle end for cooling the new energy battery).

[0006] In the existing vehicle end assembly process, after the vehicle end protection pad is assembled on one side of the vehicle end bracket, the operator needs to flip the vehicle end bracket 180 degrees to complete the installation of the protection pad on the other side of the vehicle end bracket. Manual flipping of the vehicle end bracket is inefficient and cannot meet the needs of large-scale vehicle end assembly. At the same time, the input of manpower will also lead to an increase in production costs. Moreover, after working for a long time, the operator is prone to miss flipping due to negligence, which will also affect the qualified rate of product assembly. Utility Model Content

[0033] The utility model is further described below in conjunction with the embodiments shown in the accompanying drawings.

[0034] like Figure 4-6 As shown, it is a structural schematic diagram of the flipping mechanism of the utility model, which is usually used in the assembly process of the new energy vehicle joint, and is used to flip the initially assembled joint vehicle end structure 180° to facilitate the installation of the vehicle end protection pad 40 on the other side of the vehicle end.

[0035] like Figure 1 As shown, it is a schematic diagram of the structure of the vehicle end bracket 37. The vehicle end bracket 37 has vehicle end bracket holes 38 at the four corners, which play a role of limiting when assembling the vehicle end bracket 37. There are two groups of vehicle end connecting bodies 39, which are fixed on the vehicle end bracket 37 and are used to cover the vehicle end protection pads 40.

[0036] like Figure 2 As shown, it is a schematic diagram of the structure of the vehicle end protection pad 40. The vehicle end protection pad 40 is a flexible pad, and a pad hole 41 is opened on the vehicle end protection pad 40. The diameter of the pad hole 41 is smaller than the diameter of the vehicle end connection body 39. During assembly, the vehicle end protection pad 40 is put on the vehicle end connection body 39.

[0037] like Figure 3 FIG. 2 is a schematic diagram of the structure after the vehicle end bracket 37 and the vehicle end protection pad 40 are assembled together. The vehicle end protection pad 40 is sleeved on both sides of the vehicle end bracket 37 to play a sealing role in subsequent use to prevent leakage of internal coolant. After the vehicle end protection pad 40 is assembled, a cover plate is fixed on both sides of the vehicle end bracket 37 by screws to cover the vehicle end protection pad 40.

[0038] After the vehicle end is assembled, it is plugged into the package end of the car connector, so that it can be used in the cooling system of the new energy vehicle (the package end is connected to the new energy battery, the vehicle end is connected to the driving device of the car, and the package end and the vehicle end are connected with coolant for cooling the new energy battery). The flipping mechanism of the utility model is used to flip the vehicle end structure, flipping the vehicle end bracket 37 with the vehicle end protection pad 40 installed on one side by 180 degrees, so as to facilitate the installation of the vehicle end protection pad 40 on the other side of the vehicle end bracket 37.

[0039] The flip mechanism includes a bottom plate 1, a slide rail 2, a slider 3, a moving plate 4, a cylinder fixing plate 5, a moving cylinder 6, a diagonal brace 7, a supporting block 8, a card slot 9, a through slot 10, an inner card plate 11, a connecting column 12, an outer card plate 13, a fixing block 14, a limiting screw 15, a hydraulic buffer 1 16, a vertical plate 17, a reinforcing plate 18, a lifting slide 19, a lifting plate 20, a rotating cylinder 21, a fixing plate 22, a avoiding groove 23, a hydraulic buffer 2 24, a contact plate 25, a flip plate 26, a finger cylinder 27, an outer fixing groove 28, an outer clamping plate 29, an extension plate 30, an inner fixing groove 31, an inner clamping plate 32, a storage platform 33, a carrier plate 34, a limiting column 35 and a guide portion 36. The bottom plate 1 is a rectangular plate, which is fixed on the vehicle end assembly machine by screw fastening, and the bottom plate 1 plays a bearing role.

[0040] The slide rail 2 is fixed on the bottom plate 1 by screw fastening and is parallel to the long side of the bottom plate 1. The slider 3 is slidably mounted on the slide rail 2. The moving plate 4 is fixed on the slider 3. When the moving cylinder 6 drives the moving plate 4 to move, it will drive the slider 3 to move synchronously along the slide rail 2 to improve the stability of the moving plate 4 when moving.

[0041] The cylinder fixing plate 5 is vertically fixed on the top of the bottom plate 1 and located on one side of the slide rail 2. The diagonal brace 7 is fixed between the bottom plate 1 and the cylinder fixing plate 5 to improve the structural strength of the cylinder fixing plate 5 and prevent the cylinder fixing plate 5 from affecting the normal movement of the moving plate 4 due to deformation. The cylinder body of the moving cylinder 6 is fixed on the cylinder fixing plate 5. The guide rod of the moving cylinder 6 is connected to the moving plate 4 to drive the moving plate 4 to move. Then the clamping plate is driven close to the carrier plate 34 to clamp the vehicle end bracket 37 on the carrier plate 34.

[0042] like Figure 7 As shown, it is a structural schematic diagram of the supporting block 8. The supporting block 8 is fixed on one side of the moving plate 4 close to the cylinder fixed plate 5. When the moving cylinder 6 drives the moving plate 4 to move, the supporting block 8 is used to increase the contact area with the moving plate 4, thereby reducing the pressure per unit area and ensuring the stability of the horizontal movement of the moving plate 4.

[0043] The card slot 9 is in a "U" shape and is provided on one side of the supporting block 8 close to the moving plate 4. The through slot 10 is provided at the bottom of the card slot 9 and penetrates the supporting block 8. The inner card plate 11 is provided in the card slot 9, and the thickness of the inner card plate 11 is less than the thickness of the card slot 9. No matter when the moving cylinder 6 is extended or retracted, the inner card plate 11 is always out of contact with the moving plate 4, and always relies on the large-area supporting block 8 to drive the moving plate 4 to move, so as to reduce the pressure per unit area.

[0044] The connecting column 12 is integrally connected to one side of the inner card plate 11 and is placed in the through groove 10, and the outer card plate 13 is integrally connected to the other side of the connecting column 12 and abuts against the supporting block 8. The outer card plate 13 is connected to the piston rod of the moving cylinder 6. When the piston rod of the moving cylinder 6 moves forward, the outer card plate 13 moves against the supporting block 8, thereby driving the moving plate 4 to move forward horizontally synchronously; when the piston rod of the moving cylinder 6 moves backward, the inner card plate 11 abuts against the card slot 9 and drives the supporting block 8 to move backward. By providing the card slot 9, the through groove 10, the inner card plate 11, the connecting column 12 and the outer card plate 13, the small area contact with the moving plate 4 is transformed into a large area contact with the supporting block 8, so as to reduce the pressure per unit area and improve the stability of the horizontal movement of the moving plate 4, thereby further ensuring the stability of the clamping plate clamping vehicle end bracket 37.

[0045] The vertical plate 17 is fixed vertically on the top of the moving plate 4, and the vertical plate 17 is used to fix and install the lifting slide 19. In order to improve the structural strength of the vertical plate 17, at least two groups of "L"-shaped reinforcement plates 18 are fixed between the vertical plate 17 and the moving plate 4. The fixed block 14 is fixed on the top of the bottom plate 1 and is located on both sides of the slide rail 2. The fixed block 14 is "T" shaped, and each group of fixed blocks 14 is respectively fixed with a limit screw 15 and a hydraulic buffer 16. The limit screw 15 and the hydraulic buffer 16 are matched with the vertical plate 17 to limit the position of the moving vertical plate 17.

[0046] The moving cylinder 6 drives the moving plate 4 and the vertical plate 17 to move toward one side of the carrier plate 34. When they move to a suitable clamping position, the two sides of the vertical plate 17 respectively abut against the limit screws 15 and the oil pressure buffer 16. The limit screws 15 are used to limit the vertical plate 17 to prevent it from exceeding or deviating from the original position.

[0047] The hydraulic buffer 16 can effectively absorb the noise generated by high-speed movement, convert kinetic energy into heat energy and release it into the atmosphere, so the moving object can be stopped smoothly and effectively in each movement. Through the effective cooperation of the moving cylinder 6, the limit screw 15 and the hydraulic buffer 16, the position of the moving plate 4 is accurately controlled, and the accuracy of the subsequent clamping plate when clamping the vehicle end bracket 37 is improved.

[0048] The lifting slide 19 is fixed on the side of the vertical plate 17 away from the moving cylinder 6, and is used to drive the lifting plate 20 to do lifting and lowering movements. The cylinder body of the rotating cylinder 21 is fixed on the lifting plate 20, and the flip plate 26 is fixed on the rotating part of the rotating cylinder 21. The rotating cylinder 21 drives the flip plate 26 to rotate, and then drives the clamping plate to flip the vehicle end bracket 37 180°, so that the vehicle end protection pad 40 can be installed on the other side of the vehicle end bracket 37.

[0049] like Figure 8 , 9 As shown, the fixed plate 22 is fixed on the cylinder body of the rotary cylinder 21 and is located below the rotating part of the rotary cylinder 21. An arc-shaped avoidance groove 23 is provided on the top of the fixed plate 22 to avoid interference between the rotating part of the rotary cylinder 21 and the fixed plate 22 below when the rotating part of the rotary cylinder 21 rotates. The contact plate 25 is fixed on the rotating part of the rotary cylinder 21, and there are two groups of hydraulic buffers 24, which are respectively fixed on both sides of the fixed plate 22 and matched with the contact plate 25. When the rotating part of the rotary cylinder 21 rotates, the contact plate 25 will periodically contact the hydraulic buffers 24, thereby effectively absorbing the noise generated by high-speed movement, converting kinetic energy into heat energy and releasing it into the atmosphere, and stopping the moving object smoothly and effectively in each action.

[0050] The flip plate 26 is fixed on the rotating part of the rotating cylinder 21, and the rotating cylinder 21 drives the flip plate 26 to rotate 180°, so that the vehicle end protection pad 40 can be installed on the other side of the vehicle end bracket 37. The finger cylinder 27 is fixed on the side of the flip plate 26 away from the lifting plate 20, and is used to clamp the vehicle end bracket 37 on the carrier plate 34, and flip the vehicle end bracket 37 180° under the drive of the rotating cylinder 21, and reinsert the flipped vehicle end bracket 37 on the limiting column 35, so that the vehicle end protection pad 40 can be installed on the other side of the vehicle end bracket 37.

[0051] The finger cylinder 27 has two sets of mounting plates arranged opposite to each other, and the finger cylinder 27 drives the two sets of mounting plates to move synchronously inward or outward, thereby driving the clamping plates on both sides to move, and completing the pick-up and placement action of the vehicle end bracket 37. An outer fixing groove 28 is provided on the opposite side of the mounting plate.

[0052] like Fig.10 As shown, it is a schematic diagram of the structure of the splint, which includes an outer splint 29, an extension plate 30, an inner fixing groove 31 and an inner splint 32. The outer splint 29 is fixed in the outer fixing groove 28 on the outer side of the mounting plate. By setting the outer fixing groove 28, the outer splint 29 can be limited to avoid vertical displacement of the outer splint 29 during long-term clamping work.

[0053] The extension plate 30 is integrally connected to one side of the outer clamping plate 29 and is tapered. When the vehicle end bracket 37 is clamped, the turning track of the extension plate 30 is shortened to avoid interference with the carrier plate 34. An inner fixing groove 31 is provided on the inner side of the extension plate 30. The inner clamping plate 32 is clamped in the inner fixing groove 31 and then fixed by screws. The inner clamping plate 32 can also be limited by providing the inner fixing groove 31 to prevent the inner clamping plate 32 from being offset.

[0054] The inner clamping plate 32 is made of rubber, which can avoid scratches on the outer side of the vehicle end bracket 37 when clamping and flipping the vehicle end bracket 37.

[0055] The storage platform 33 is fixed on the bottom plate 1 and is located on one side of the slide rail 2. The carrier plate 34 is fixed on the top of the storage platform 33 and is used to carry the vehicle end bracket 37 to be assembled. A plurality of groups of limiting columns 35 are fixed on the top of the carrier plate 34, and the limiting columns 35 are matched with the vehicle end bracket holes 38 of the vehicle end bracket 37. During actual assembly, the vehicle end bracket holes 38 are inserted on the limiting columns 35.

[0056] A truncated cone-shaped guide portion 36 is provided on the top of the limiting column 35 to guide the inserted vehicle end bracket 37 to ensure that the vehicle end bracket 37 is more easily inserted into the limiting column 35 .

[0057] The flipping principle of the flipping mechanism of the utility model is as follows:

[0058] First, place the preliminarily assembled vehicle-end bracket 37 on the carrier plate 34 (the vehicle-end bracket hole 38 is inserted on the limiting column 35, and the preliminarily assembled vehicle-end bracket 37, that is, one side of the vehicle-end bracket 37 has been installed with the vehicle-end protection pad 40, but the other side is in a waiting state), and the vehicle-end bracket 37 on the carrier plate 34 is clamped by the clamping plate under the drive of the moving cylinder 6, the lifting slide 19 and the finger cylinder 27, and then the vehicle-end bracket 37 is flipped 180° under the action of the rotating cylinder 21, and then reinserted into the limiting column 35, thereby completing its flipping work.

[0059] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with the technology to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
