Technical Field
[0001] This utility model relates to the field of folding technology, and in particular, to a folding device for automated automobile production. Background Technology
[0002] Folding equipment is needed in the production of car doors, hoods, and rear hoods. It is used to create snaps by bending the edges of the doors and hoods to facilitate subsequent assembly and welding. With the continuous improvement and perfection of technology, current folding equipment can achieve automated production. For example, the most common folding equipment now includes a telescopic cylinder and a folding plate. The folding plate is installed at the extended end of the telescopic cylinder. When in use, the extended end of the telescopic cylinder extends outward, thereby driving the folding plate to move and bend the workpiece to be folded.
[0003] In practical work, as the usage time increases, the folding plate often needs to be frequently disassembled and repaired due to deformation or wear. Therefore, how to achieve rapid disassembly and assembly of the folding plate becomes the first issue to consider when designing folding equipment. For example, Chinese utility model patent CN217018216U discloses a folding mechanism for automotive welding. During installation, the output shaft of the folding cylinder is first retracted. After completion, the fixing cover on the outside of the fixing joint is rotated open, and the snap-fit block on the folding plate is spliced with the snap-fit groove in the fixing joint. Then, the fixing cover is rotated to fix it. At this time, the operator starts the folding cylinder, and the output shaft of the folding cylinder drives the folding plate forward, so that the stabilizing slide rod in the folding plate enters the stabilizing groove in the mounting base plate, thus completing the installation. The proposed solution allows operators to quickly disassemble and assemble the folded plate without the need for external tools. However, in order to improve the fixing strength, the fit force between the threads of the fixing cover and the fixing joint is usually large, which requires a lot of force in the initial stage of loosening. Moreover, the operation of repeatedly rotating the fixing cover when loosening or tightening is also cumbersome. The disassembly and assembly efficiency and user experience need to be improved. Utility Model Content
[0004] The technical problem to be solved by this utility model is: in order to overcome the above-mentioned defects in the prior art, a folding device for automated automobile production with high disassembly and assembly efficiency is provided.
[0005] The technical solution adopted by this utility model to solve its technical problem is: a bending device for automated automobile production, including a base plate, a bending cylinder and a bending plate. The bending cylinder is mounted on the base plate and is used to drive the bending plate to move. The extended end of the bending cylinder is connected to a fixed joint. A fixed sleeve is connected to the bending plate. A groove is provided on the outer wall of the fixed joint. A locking block is movably provided in the groove. The locking block can extend out or be received in the groove. A spring is provided in the groove that can extend and retract along the moving direction of the locking block. A slot that mates with the fixed joint is provided on the fixed sleeve. A slot that aligns with the locking block is provided on the outer wall of the fixed sleeve. When the end of the fixed joint is inserted into the slot until the end of the fixed joint abuts against the bottom wall of the slot, the locking block extends out into the groove and is locked into the slot under the action of the elastic element.
[0006] Furthermore, the side of the card block closest to the bending plate is configured with a sloping structure.
[0007] Furthermore, chamfers are provided on the corners of the card block away from the bending plate and on the edges of the card slot away from the bending plate.
[0008] Furthermore, there are two card blocks, which are respectively disposed on the opposite side walls of the fixed joint, and there are two card slots, one of which is engaged with one card block.
[0009] Furthermore, a spring sheet is connected to the outer wall of the fixing sleeve, and a pressure post is fixedly connected to the end of the spring sheet away from the fixing sleeve. The pressure post has a corresponding slot located on the outside of the fixing sleeve.
[0010] Furthermore, the substrate has a U-shaped structure, and a sliding channel is formed on the substrate, within which the bent plate moves.
[0011] Furthermore, the bending plate has a U-shaped structure and includes two opposing bending blocks and a connecting plate between the two bending blocks. Guide wheels are rotatably mounted on the relatively distant surfaces of the two bending blocks, and the guide wheels are disconnected from the channel wall of the sliding channel.
[0012] Furthermore, a guide groove is provided on the channel wall of the sliding channel, and the guide wheel cooperates with the guide groove and can roll within the guide groove.
[0013] Furthermore, the end of the bending block away from the connecting plate is bent outward to form a bent portion, and an inclined surface is provided at the connection between the bent portion and the bending block. An auxiliary wheel is rotatably mounted on the bent portion, and the auxiliary wheel can roll within the guide groove.
[0014] Furthermore, the base plate includes two opposing limiting plates and a fixing plate fixed between the two limiting plates. The bending cylinder is fixedly connected to one side of the fixing plate. A support sleeve is fixedly connected to the side wall of the cylinder body on the fixing plate away from the bending cylinder. The protruding end of the bending cylinder can slide through the support sleeve.
[0015] The beneficial effects of this utility model are as follows: During installation, the user only needs to fit the fixing sleeve onto the fixing joint from the end of the fixing joint to achieve the locking relationship between the two. When releasing the locking relationship between the locking block and the locking groove, the fixing sleeve can be easily removed from the fixing joint. Compared with the prior art, this utility model can realize the disassembly and assembly between the bending plate and the bending cylinder through a simple plugging and unplugging action, which simplifies the operation, improves the disassembly and assembly efficiency, and greatly improves the user experience.

[0020] The present invention will now be described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.
[0021] Please see Figure 1 , Figure 2This utility model provides a bending device for automated automotive production, including a base plate 10, a bending cylinder 20, and a bending plate 30. The bending cylinder 20 is fixedly mounted on the base plate 10, and the bending plate 30 is mounted on the extended end of the bending cylinder 20. In use, the bending cylinder 20 is activated, thereby moving the bending plate 30 to bend the workpiece to be bent. The bending plate 30 and the bending cylinder 20 are detachably connected, facilitating the removal and repair of the bending plate 30, thus solving the problems of wear and deformation of the bending plate 30.
[0022] The substrate 10 is generally U-shaped. The substrate 10 includes two opposing limiting plates 11 and a fixing plate 12 fixedly connected between the two limiting plates 11. The two limiting plates 11 are arranged parallel to each other, and the fixing plate 12 is perpendicular to the limiting plates 11. The space between the two limiting plates 11 forms a sliding channel 110. The bending plate 30 moves along the length direction of the limiting plates 11 within the sliding channel 110.
[0023] A through hole 121 is provided on the fixed plate 12, and the vertical distance from the through hole 121 to the two limiting plates 11 is the same. The cylinder body of the bending cylinder 20 is fixedly connected to the side wall of the fixed plate 12 away from the sliding channel 110. The output end of the bending cylinder 20 passes through the through hole 121 and extends into the sliding channel 110, and the extended end of the bending cylinder 20 is slidable relative to the through hole 121. In this embodiment, an mounting plate 201 is fixedly sleeved on the outside of the cylinder body end of the bending cylinder 20. The mounting plate 201 is in contact with the fixed plate 12, and the mounting plate 201 and the fixed plate 12 are fixedly connected by bolts 202. To achieve balanced force, the mounting plate 201 has a circular structure, and there are multiple bolts 202, which are evenly arranged along the circumference of the mounting plate 201.
[0024] In addition, a support sleeve 122 is fixedly connected to the side wall of the cylinder body away from the bending cylinder 20 on the fixed plate 12. The two ends of the support sleeve 122 are open, and the support sleeve 122 is set corresponding to the through hole 121. The support sleeve 122 and the through hole 121 are coaxial, and the protruding end of the bending cylinder 20 can slide through the support sleeve 122. In use, the support sleeve 122, which is coaxial with the through hole 121, can limit and support the protruding end of the bending cylinder 20, ensuring the stability of the movement of the protruding end of the bending cylinder 20, improving the structural strength of the protruding end of the bending cylinder 20, and preventing easy deformation.
[0025] The bending plate 30 is roughly U-shaped and includes two opposing bending blocks 31 and a connecting plate 32 connecting the two bending blocks 31. The two bending blocks 31 are parallel to each other, and the connecting plate 32 is perpendicular to the bending blocks 31. In addition, two limiting plates 11 are parallel to the two bending blocks 31. The bending blocks 31 can move along the length direction of the limiting plates 11 under the action of the bending cylinder 20. The limiting plates 11 can play a good guiding role in the movement of the bending blocks 31.
[0026] In this embodiment, guide wheels 33 are rotatably mounted on the relatively distant surfaces of the two bending blocks 31. The guide wheels 33 are in contact with the limiting plate 11 (i.e., the channel wall of the sliding channel 110). During operation, when the bending blocks 31 move under the drive of the bending cylinder 20, the guide wheels 33 can roll along the surface of the limiting plate 11. The setting of the guide wheels 33, on the one hand, guides the movement of the bending blocks 31, and on the other hand, reduces the friction between the bending blocks 31 and the limiting plate 11, which is conducive to the smooth movement of the bending blocks 31.
[0027] Furthermore, the end of the bending block 31 furthest from the connecting plate 32 is bent outward to form a bent portion 311. An inclined surface 312 is provided at the connection between the bent portion 311 and the bending block 31. The inclined surface 312 is used to push against the workpiece to be bent when the bending block 31 moves. The provision of the bent portion 311 enhances the structural strength around the inclined surface 312. Further, an auxiliary wheel 34 is rotatably mounted on the bent portion 311. The auxiliary wheel 34 also contacts the limiting plate 11. At this time, when the bending block 31 moves under the drive of the bending cylinder 20, the auxiliary wheel 34 also rolls along the surface of the limiting plate 11, thereby effectively supporting and guiding the bent portion 311.
[0028] In one specific embodiment, guide grooves 111 are provided on the opposing surfaces of the two limiting plates 11 (i.e., the channel walls of the sliding channel 110) along the length direction of the limiting plates 11. The guide wheels 33 and auxiliary wheels 34 cooperate with the guide grooves 111 and can roll within the guide grooves 111. The guide grooves 111 guide and limit the guide wheels 33 and auxiliary wheels 34, preventing the bending plate 30 from separating from the base plate 10 and ensuring the stable movement of the bending plate 30.
[0029] In this embodiment, a fixed connector 40 is fixedly connected to the extended end of the bending cylinder 20, and a fixed sleeve 50 is fixedly connected to the bending plate 30. The fixed connector 40 and the fixed sleeve 50 are detachably fixedly connected to achieve a detachable connection between the bending plate 30 and the bending cylinder 20.
[0030] A groove 41 is provided on the outer wall of the fixed connector 40. A locking block 42 is movably installed in the groove 41. The locking block 42 can be received in the groove 41 or partially protrude out of the groove 41. A spring 43 is provided in the groove 41 in a telescopic manner along the movement direction of the locking block 42. A slot 51 that mates with the fixed connector 14 is provided on the fixed sleeve 50. A groove 52 that aligns with the locking block 42 is provided on the outer wall of the fixed sleeve 50. When the end of the fixed connector 40 is inserted into the slot 51 until the end of the fixed connector 40 abuts against the bottom wall of the slot 51, the locking block 42 extends out of the groove 41 and is locked into the groove 52 under the action of the elastic member 43.
[0031] Before installing the fixed sleeve 50 and the fixed connector 40, the locking block 42 and the locking groove 52 are aligned to ensure that the locking block 42 can be locked into the locking groove 52 when the fixed connector 40 is inserted into the fixed sleeve 50. During the specific connection, the bending plate 30 moves along the sliding channel 110 towards the bending cylinder 20. At this time, the locking block 42 is pressed into the groove 41 so that the fixed connector 40 is gradually inserted into the slot 51. After the insertion is in place, the end of the fixed connector 40 away from the bending cylinder 20 abuts against the bottom wall of the slot 51. At the same time, the locking block 42 and the locking groove 52 are aligned, the spring 43 is reset, and the locking block 42 is pushed outward into the locking groove 52. At this time, one end of the locking block 42 and the bottom wall of the slot 52 mutually limit and abut against each other, and the fixed sleeve 50 and the fixed connector 40 are locked. At this time, the fixed sleeve 50 cannot move axially relative to the fixed connector 40. In addition, during actual operation, the end of the fixed joint 40 abuts against the bottom wall of the slot 51 for the bending cylinder 20 to drive the bending plate 30 to move to bend the workpiece to be bent, while the limiting abutment between the locking block 42 and the locking slot 52 is used to drive the bending plate 30 to reset when the extended end of the bending cylinder 20 retracts.
[0032] When the bending plate 30 needs to be repaired after a period of use, the user presses the locking block 42 inward to retract it into the groove 41. At this time, the locking block 42 is separated from the groove 52, and the user can then remove the fixing sleeve 50 from the fixing joint 40. The operation is simple and convenient.
[0033] In one specific embodiment, the side of the card block 42 near the bending plate 30 is set with a bevel structure. In this way, when the fixing connector 40 is inserted into the fixing sleeve 50, the opening edge of the slot 51 moves with the fixing sleeve 50 and can gradually press the card block 42 into the groove 41 under the action of the bevel structure. This eliminates the trouble for the user to press the card block 42 into the groove 41 before installation and greatly facilitates the operation.
[0034] In addition, chamfers 421 are provided on the corners of the card block 42 away from the bending plate 30 and on the edge of the card slot 52 away from the bending plate 30, so that the card block 42 can be smoothly inserted into the card slot 52.
[0035] Furthermore, there are two locking blocks 42, which are respectively disposed on the opposite side walls of the fixed joint 40. Correspondingly, there are also two locking slots 52, with one locking slot 52 engaging with one locking block 42.
[0036] One end of the spring 43 is fixedly connected to the bottom wall of the groove 41, and the other end of the spring 43 is fixedly connected to the locking block 42.
[0037] In a preferred embodiment, a spring piece 53 is connected to the outer wall of the fixing sleeve 50. A pressure post 54 is fixedly connected to the end of the spring piece 53 away from the fixing sleeve 50. The pressure post 54 corresponds to the slot 52 located on the outside of the fixing sleeve 50. When the user needs to release the lock between the locking block 42 and the slot 52, the pressure post 54 can be pressed inward, causing the pressure post 54 to squeeze the locking block 42 inward, ultimately disengaging the locking block 42 from the slot 52. When the pressing action on the pressure post 54 is released, the spring piece 53 resets, thereby driving the pressure block 54 back to its initial position.
[0038] This utility model relates to a bending device for automated automotive production. During installation, the user simply needs to fit the fixing sleeve 50 onto the fixing joint 40 from the end of the fixing joint 40 to achieve a locking relationship between the two. When releasing the locking relationship between the locking block 42 and the locking groove 52, the fixing sleeve 50 can be easily removed from the fixing joint 40. Compared with the prior art, this utility model can realize the disassembly and assembly of the bending plate 30 and the bending cylinder 20 through a simple plugging and unplugging action, which simplifies the operation, improves the disassembly and assembly efficiency, and greatly improves the user experience.
[0039] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the scope of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
