Description
Technical Field
[0001] The present invention relates to the field of automobile assembly, in particular to an automated automobile leaf spring assembly platform. Background Art
[0002] Automobile leaf spring is the most traditional elastic element in automobile suspension system, which has the advantages of good reliability, simple structure, short manufacturing process, low cost and greatly simplified structure.
[0003] The main function of automobile leaf springs is to serve as elastic elements of automobile suspension systems. In addition, the friction between the leaves of the multi-leaf springs plays a damping role in the system. Most automobile leaf springs also have a guiding function through the ears and supports.
[0004] An existing patent (publication number: CN114604633B) discloses a robotic arm electromagnetic chuck transfer device for automotive leaf spring production. The device comprises two symmetrically arranged front plate seats, connected by a rear plate seat. Each front plate seat is equipped with a slidable rack and a drive mechanism for driving the rack. The rack is toothed on both its upper and lower sides. A first and second gears are mounted on the front ends of the front plate seats, rotating from back to front. The first and second gears mesh with the upper and lower teeth of the racks, respectively. A rear clamping rod and a front clamping rod are fixed to the corresponding rotating shafts of the first and second gears, respectively. A transverse axis is rotatably mounted between the two front plate seats, with a third gear coaxially fixed to the transverse axis, which engages with the upper teeth of the racks. A support rod is positioned in the middle of the transverse axis, and an electromagnetic chuck is positioned between the rear and front clamping rods. This device ensures stable transport of leaf springs while preventing deformation during transport, thereby ensuring processing quality. In the process of realizing the present invention, the inventors found that there are at least the following problems in the prior art that have not been solved: a group of automobile leaf springs is composed of individual leaf springs of different specifications and lengths, which are composed in sequence according to the length of the leaf springs. When assembling the automobile leaf springs, each leaf spring of different lengths needs to be assembled separately. When the automobile leaf springs are clamped by a clamping member, the clamping force of the clamping member on the automobile leaf spring will cause the automobile leaf spring to shrink when clamped, and then the center points of each leaf spring cannot be aligned during assembly. After clamping, the center point of the leaf spring needs to be found for calibration, which affects the efficiency of leaf spring assembly. Summary of the Invention

[0015] Compared with the prior art, the present invention has the following beneficial effects:
[0016] In the present invention, the movable control part is driven by the driving rotating part to deflect on the side wall of the clamping support seat. When the movable control part moves away from the other side of the driving rotating part, the clamping end of the clamping part will open and close. The locking part controls the position of the movable control part to adjust the opening and closing size of the clamping part to facilitate the clamping of leaf springs of different specifications.
[0017] In the present invention, the driving plate can be driven to move back and forth under the drive of the driving rotating member, and the driving plate and the transmission member are in transmission cooperation. The reciprocating movement of the driving plate can intermittently drive the intermittent rotation of the outer ratchet disk, and the transmission cooperation between the outer ratchet disk and the locking member can intermittently adjust the position of the locking member, which is convenient for the subsequent clamping member to adjust the clamping force of the leaf spring when clamping and transporting the leaf spring.
[0018] In the present invention, when the locking plate moves, the locking block on the locking plate will move to the card interface in the moving groove. The compression spring plate on the locking plate will then abut against the abutment groove on the locking block, thereby restricting the locking block in the card interface, and making the reset spring in a compressed state unable to drive the locking plate to reset.
[0019] In the present invention, the locking plate moves in the moving groove toward the end close to the transmission member, and the locking block contacts the slope in the moving groove. Under the restriction of the slope, the locking block is deflected and reset on the locking plate, and the compression spring plate and the abutment groove on the locking plate abut again, so that during the clamping and transportation process of the automobile leaf spring, when the assembly quantity of each group of automobile leaf springs is completed, the locking plate can be reset to the initial state, and each group of automobile leaf springs can be repeatedly clamped and transported.
[0020] In the present invention, the card wheel on the movable frame is the bracket of the tilting arm bracket. When the tilting arm bracket is deflected by the eccentric frame, the other end of the tilting arm bracket will cause the pressure rod to move back and forth up and down on the clamping support seat through the positioning rod. Since the pressure rod is connected to the clamping member, when the pressure rod moves downward, it can drive the clamping member to clamp the automobile leaf spring, and when the pressure rod moves upward, it drives the clamping member to loosen the automobile leaf spring, thereby driving the clamping member to open and close through the mobile control member.
[0021] In the present invention, when the clamping wheel moves in the arc groove on the tilting arm bracket, the position of the tilting arm bracket fulcrum will be changed, so that each time the tilting arm bracket drives the pressure rod to move up and down, the distance moved by the tilting arm bracket driving the pressure rod will be shorter than the previous stroke distance. The shortened stroke distance of the pressure rod will make the opening and closing degree of the clamping part smaller. Because a group of automobile leaf springs is composed of individual leaf springs of different specifications and lengths in sequence according to the length of the leaf springs, each leaf spring of different lengths needs to be assembled separately when assembling the automobile leaf springs. Therefore, after the clamping part clamps a single leaf spring, the opening and closing degree of the clamping part can be adjusted with the cooperation of the transmission part, the locking part and the moving control part, so that after the single leaf spring is clamped and transported, the opening and closing degree can be adjusted to correspond to the length of the next leaf spring when clamping the next leaf spring, thereby facilitating the clamping and transport of a group of leaf springs.

DETAILED DESCRIPTION
[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.
[0035] See also Figures 1 to 11 The present invention provides a technical solution: an automated automobile leaf spring assembly platform, comprising a clamping support base 1, a motor base 11 being fixedly connected to the side wall of the clamping support base 1, a drive motor 12 being fixedly connected to the motor base 11, and a main shaft of the drive motor 12 being arranged toward the clamping support base 1;
[0036] It also includes a driving rotating member 2, which is arranged on the main shaft of the driving motor 12, and a limiting frame 13 is fixedly connected to the side wall of the clamping support seat 1 facing the motor seat 11. The driving rotating member 2 slides with the limiting frame 13, and a locking member 4 is also slidably provided on the top of the limiting frame 13. A transmission member 3 is also provided on the side wall of the clamping support seat 1 facing the motor seat 11. The transmission member 3 is located between the driving rotating member 2 and the locking member 4, and the transmission member 3 is in transmission cooperation with the driving rotating member 2, and The transmission member 3 is in transmission cooperation with the locking member 4. A movable control member 5 is also rotatably provided on the side wall of the clamping support 1 facing the motor base 11. The movable control member 5 is in transmission cooperation with the driving rotating member 2, and the movable control member 5 and the locking member 4 are in contact with each other. A mounting bracket 14 is fixed vertically downward on the clamping support 1. A clamping member 6 is provided on the mounting bracket 14. The clamping member 6 and the mounting bracket 14 are in sliding cooperation. The movable control member 5 is connected to the clamping member 6 on the other side away from the driving rotating member 2.
[0037] Driven by the driving motor 12, the driving rotating member 2 rotates, and the rotation of the driving rotating member 2 drives the transmission member 3 to rotate. The transmission member 3 enables the locking member 4 to intermittently move toward the moving control member 5, thereby gradually adjusting the setting position of the moving control member 5. The moving control member 5 is driven by the driving rotating member 2 to deflect at the side wall of the clamping support seat 1. When the moving control member 5 moves away from the other side of the driving rotating member 2, the clamping end of the clamping member 6 will open and close. The locking member 4 controls the position of the moving control member 5 to adjust the opening and closing size of the clamping member 6 to facilitate clamping of leaf springs of different specifications.
[0038] In this embodiment, the driving rotating member 2 includes a driving frame 21 provided on the main shaft of the driving motor 12, and the end of the driving frame 21 away from the main shaft of the driving motor 12 is fixedly connected to a fixing rod 22, and a driving plate 23 is slidably provided on the top of the limiting frame 13, and a vertical slot 24 is provided on the driving plate 23. The fixing rod 22 on the driving frame 21 is located in the vertical slot 24, and a driving rack 25 is fixedly provided on the inner wall of the driving plate 23 facing the clamping support seat 1, and the driving rack 25 is in transmission cooperation with the transmission member 3;
[0039] The transmission member 3 includes a transmission rod 31 rotatably arranged on the side wall of the clamping support seat 1, and a transmission gear 32 is fixedly connected to the transmission rod 31, and the transmission gear 32 is meshed with the driving rack 25. The transmission rod 31 is also fixedly connected to an inner ratchet disk 33, and a notch 34 is opened on the inner ratchet disk 33. A pawl 35 is hingedly connected in the notch 34 of the inner ratchet disk 33, and a connecting spring 36 is provided between the pawl 35 and the notch 34. An outer ratchet disk 37 is also rotatably provided on the outer wall of the inner ratchet disk 33, and ratchet teeth 38 that contact the pawl 35 are provided on the inner wall of the outer ratchet disk 37. A fixed gear ring 39 is fixedly connected to the outer wall of the outer ratchet disk 37, and the fixed gear ring 39 is transmission-coordinated with the locking member 4;
[0040] When the main shaft of the driving motor 12 drives the driving frame 21 to rotate, the rotation of the driving frame 21 will drive the fixed rod 22 at the other end of the driving frame 21 to rotate with the main shaft of the driving motor 12. Because the fixed rod 22 is set in the vertical slot 24 on the driving frame 21, when the fixed rod 22 rotates, the driving frame 21 will reciprocate on the limit frame 13 under the restriction of the vertical slot 24. When the driving frame 21 reciprocates, the driving rack 25 on the inner wall of the driving frame 21 will drive the transmission gear 32 to rotate. Since the driving frame 21 is reciprocating, the transmission gear 32 is driven by the driving frame 21 to rotate clockwise and counterclockwise. When the transmission gear 32 rotates clockwise, the transmission gear 32 drives the transmission rod 31 to rotate the inner ratchet plate 33, and the ratchet 35 on the inner ratchet plate 33 is embedded in the outer ratchet plate 33 under the action of the connecting spring 36. The ratchet teeth 38 on the inner wall of the ratchet plate 37 can drive the outer ratchet plate 37 to rotate clockwise. When the transmission rod 31 rotates counterclockwise, the transmission rod 31 rotates counterclockwise to drive the inner ratchet plate 33 to rotate counterclockwise, and the pawl 35 will be separated from the ratchet teeth 38 on the outer ratchet plate 37 under the action of the connecting spring 36, thereby not driving the outer ratchet plate 37 to rotate. Driven by the driving rotating member 2, the driving plate 23 can be driven to move back and forth, and the driving plate 23 and the transmission member 3 are in transmission cooperation. The reciprocating movement of the driving plate 23 can intermittently drive the intermittent rotation of the outer ratchet plate 37, and the transmission cooperation between the outer ratchet plate 37 and the locking member 4 can intermittently adjust the position of the locking member 4, which is convenient for the subsequent clamping member 6 to adjust the clamping force of the leaf spring during clamping and transportation.
[0041] In this embodiment, the locking member 4 includes a base 41 fixedly connected to the top of the limiting frame 13, a locking plate 42 is slidably provided on the base 41, and a movable gear rod 43 is fixedly connected to the locking plate 42. The movable gear rod 43 is arranged in the direction of the transmission member 3 and meshes with the fixed gear ring 39 on the outer ratchet disk 37;
[0042] The card holder 41 is provided with a movable groove 44, and a plurality of equally spaced card interfaces 441 are provided on the movable groove 44, and the plurality of card interfaces 441 are arranged in a wave shape. The two ends of the movable groove 44 are respectively arranged toward the transmission member 3 and the clamping member 6. The end of the movable groove 44 facing the transmission member 3 is provided with an inclined slope 442, and the end of the movable groove 44 facing the clamping member 6 is provided with a notch 443.
[0043] The locking plate 42 is hingedly provided with a locking block 45, and the locking block 45 is provided with an abutting groove 451 and a locking groove 452. The locking plate 42 is also rotatably provided with an elastic compression spring plate 46, and one end of the compression spring plate 46 away from the locking plate 42 abuts against the abutting groove 451 and the locking groove 452 on the locking block 45;
[0044] An adjusting rod 47 is fixedly connected to the side wall of the locking plate 42 on the side opposite to the moving gear rod 43. The adjusting rod 47 is slidably engaged with the side wall of the clamping support seat 1. A return spring 48 is sleeved on the adjusting rod 47. The two ends of the return spring 48 are respectively connected to the side wall of the clamping support seat 1 and the adjusting rod 47. A limiting wheel 49 is also rotatably provided on the adjusting rod 47, and the limiting wheel 49 abuts against the moving control member 5.
[0045] When the inner ratchet disc 33 rotates clockwise and drives the outer ratchet disc 37 to rotate, the outer ratchet disc 37 will drive the movable gear rod 43 to move toward the clamping member 6 through the fixed gear ring 39. At this time, the locking plate 42 will drive the adjusting rod 47 to move. The adjusting rod 47 squeezes the return spring 48 to put the return spring 48 in a compressed state. When the locking plate 42 moves, the locking block 45 on the locking plate 42 will move to the card interface 441 in the moving groove 44. The compression spring plate 46 on the locking plate 42 will then abut against the abutment groove 451 on the locking block 45, thereby restricting the locking block 45 in the card interface 441, so that the return spring 48 in the compressed state cannot drive the locking plate 42 to return to its original position.
[0046] Each time the outer ratchet disc 37 rotates and drives the locking plate 42 to move, the adjusting rod 47 on the locking plate 42 drives the limiting wheel 49 to adjust the position of the movable control member 5. As a result, when the movable control member 5 drives the clamping member 6 to open and close and clamp the leaf spring, the opening and closing degree of the clamping member 6 can be gradually adjusted.
[0047] When the clamping member 6 gradually clamps the leaf springs of different sizes and clamps the last leaf spring, the locking plate 42 will move in the moving groove 44 to one end close to the clamping member 6. At this time, the locking block 45 will come into contact with the notch 443. Under the resistance of the notch 443, the deflection amplitude of the locking block 45 on the locking plate 42 becomes larger, and the locking groove 452 on the locking block 45 will come into contact with the compression spring plate 46. The compression spring plate 46 limits the locking block 45. The locking block 45 is no longer in contact with the card interface 441 in the moving groove 44 at this time, and then driven by the return spring 48, The locking plate 42 can be moved and reset, and the locking plate 42 moves in the moving groove 44 toward the end close to the transmission member 3, and the locking block 45 will contact the slope 442 in the moving groove 44. Under the restriction of the slope 442, the locking block 45 is deflected and reset on the locking plate 42, and the compression spring plate 46 is again in contact with the abutment groove 451 on the locking plate 42, so that during the clamping and transportation process of the automobile leaf spring, when the assembly quantity of each group of automobile leaf springs is completed, the locking plate 42 can be reset to the initial state, and each group of automobile leaf springs can be repeatedly clamped and transported.
[0048] In this embodiment, the movement control member 5 includes a moving frame 51 provided on the outer wall of the clamping support seat 1 facing the motor seat 11, the moving frame 51 is rotatably matched with the outer wall of the clamping support seat 1, a vertically arranged connecting groove 52 is provided on the moving frame 51, the limiting wheel 49 on the adjusting rod 47 is in the connecting groove 52, and the end of the moving frame 51 away from the clamping support seat 1 is rotatably provided with a card wheel 53, the driving rotating member 2 also includes a driving disk 26 provided on the main shaft of the driving motor 12, and an eccentric frame 27 is eccentrically provided on the driving disk 26. The control member 5 also includes a tilting rod bracket 54 hingedly arranged on the eccentric frame 27, and a pressure rod 55 is slidably arranged on the clamping support seat 1 above the clamping member 6. The pressure rod 55 is provided with a vertically arranged through-groove 56, and a positioning rod 57 is arranged vertically in the through-groove 56. The other end of the tilting rod bracket 54 away from the eccentric frame 27 is hingedly matched with the positioning rod 57. The tilting rod bracket 54 is also provided with a semi-arc-shaped arc groove 58. The card wheel 53 on the movable frame 51 is located in the arc groove 58. The bottom of the pressure rod 55 is fixedly connected to the clamping member 6;
[0049] When the driving motor 12 drives the driving disc 26 to rotate, the driving disc 26 rotates and drives the eccentric frame 27 to rotate around the driving disc 26 as the center of the circle. The other end of the eccentric frame 27 pulls the hinged tilting rod bracket 54 to move. The card wheel 53 on the movable frame 51 is the bracket of the tilting rod bracket 54. When the tilting rod bracket 54 is deflected by the eccentric frame 27, the other end of the tilting rod bracket 54 causes the pressure rod 55 to move up and down on the clamping support seat 1 through the positioning rod 57. Since the pressure rod 55 is connected to the clamping member 6, when the pressure rod 55 moves downward, it can drive the clamping member 6 to clamp the automobile leaf spring, and when the pressure rod 55 moves upward, it drives the clamping member 6 to loosen the automobile leaf spring, thereby driving the clamping member 6 to open and close through the mobile control member 5;
[0050] When the driving motor 12 drives the driving disc 26 to rotate one circle, the driving frame 21 rotates one circle synchronously, and the driving frame 21 drives the driving plate 23 to reciprocate, so that each time the driving disc 26 rotates to control the moving control member 5 to open and close the clamping member 6, the driving of the transmission member 3 and the locking member 4 can adjust the deflection of the moving frame 51 on the outer wall of the clamping support seat 1, and each deflection of the moving frame 51 can drive the card wheel 53 provided at the bottom of the moving frame 51 to move, and when the card wheel 53 moves in the arc groove 58 on the tilting rod bracket 54, the position of the fulcrum of the tilting rod bracket 54 is changed, so that each time the tilting rod bracket 54 drives the pressure rod 55 to move up and down, the tilting rod bracket 54 The distance that the pressure rod 55 moves will be shorter than the previous stroke distance. The shortened stroke distance of the pressure rod 55 will reduce the opening and closing degree of the clamping member 6. Because a group of automobile leaf springs is composed of single leaf springs of different specifications and lengths according to the length of the leaf springs, each leaf spring of different lengths needs to be assembled separately when assembling the automobile leaf springs. Therefore, after the clamping member 6 clamps a single leaf spring, the opening and closing degree of the clamping member 6 can be adjusted with the cooperation of the transmission member 3, the locking member 4 and the moving control member 5, so that after the single leaf spring is clamped and transported, the opening and closing degree can be adjusted to correspond to the length of the next leaf spring when clamping the next leaf spring, thereby facilitating the clamping and transportation of a group of leaf springs.
[0051] In this embodiment, the clamping member 6 includes a control rod 61 slidably arranged on the mounting frame 14, the control rod 61 and the pressure rod 55 are on the same axis, and the top of the control rod 61 is fixedly connected to the bottom of the pressure rod 55, and the bottom of the control rod 61 is fixedly connected to a control plate 62, and two articulated frames 63 are hingedly provided on opposite sides of the control plate 62 on the mounting frame 14, one of the articulated frames 63 on the same side is arranged close to the control plate 62, and a connecting plate 64 is hingedly provided between the articulated frame 63 close to the control plate 62 and the control plate 62, and a clamping plate 65 is hingedly provided at the other end of the two articulated frames 63 away from the mounting frame 14;
[0052] When the lower pressure rod 55 moves downward, the lower pressure rod 55 will drive the control rod 61 to move downward on the mounting frame 14. The downward movement of the control rod 61 will drive the control plate 62 to move downward. The control plate 62 will drive the hinged connecting plate 64 to expand outward, thereby causing the hinged frame 63 close to the side of the control plate 62 to expand in the direction away from the control plate 62, and the other hinged frame 63 plays a limiting role. At this time, the clamping plates 65 set on the two hinged frames 63 will expand outward, and the automobile leaf spring to be assembled will be clamped by the two relatively arranged clamping plates 65, thereby realizing the clamping and assembly operation of the automobile leaf spring.
[0053] The use method and advantages of the present invention: The use method of the automated automobile leaf spring assembly platform, the working process is as follows:
[0054] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 、 Figure 11 As shown: when the main shaft of the driving motor 12 drives the driving frame 21 to rotate, the rotation of the driving frame 21 will drive the fixed rod 22 at the other end of the driving frame 21 to rotate with the main shaft of the driving motor 12. Because the fixed rod 22 is set in the vertical slot 24 on the driving frame 21, and then when the fixed rod 22 rotates, the driving frame 21 will reciprocate on the limit frame 13 under the restriction of the vertical slot 24. When the driving frame 21 reciprocates, the driving rack 25 on the inner wall of the driving frame 21 will drive the transmission gear 32 to rotate. Since the driving frame 21 is reciprocating, the transmission gear 32 is driven by the driving frame 21 to realize clockwise and counterclockwise rotation. When the transmission gear 32 rotates clockwise, the transmission gear 32 drives the transmission rod 31 to make the inner ratchet As the wheel disc 33 rotates, the pawl 35 on the inner ratchet disc 33 is embedded in the ratchet teeth 38 on the inner wall of the outer ratchet disc 37 under the action of the connecting spring 36, thereby driving the outer ratchet disc 37 to rotate clockwise. When the transmission rod 31 rotates counterclockwise, the transmission rod 31 rotates counterclockwise to drive the inner ratchet disc 33 to rotate counterclockwise, and the pawl 35 is separated from the ratchet teeth 38 on the outer ratchet disc 37 under the action of the connecting spring 36, thereby not driving the outer ratchet disc 37 to rotate. Driven by the driving rotating member 2, the driving plate 23 can be driven to reciprocate, and the driving plate 23 and the transmission member 3 are in transmission cooperation. The reciprocating movement of the driving plate 23 can intermittently drive the intermittent rotation of the outer ratchet disc 37.
[0055] When the inner ratchet disc 33 rotates clockwise and drives the outer ratchet disc 37 to rotate, the outer ratchet disc 37 drives the movable gear rod 43 to move toward the clamping member 6 through the fixed gear ring 39. At this time, the locking plate 42 drives the adjusting rod 47 to move. The adjusting rod 47 squeezes the return spring 48 to compress the return spring 48. When the locking plate 42 moves, the locking block 45 on the locking plate 42 moves to the card interface 441 in the moving groove 44. The compression spring plate 46 on the locking plate 42 now abuts against the abutment groove 451 on the locking block 45, thereby restricting the locking block 45 in the card interface 441.
[0056] Each time the outer ratchet disc 37 rotates and drives the locking plate 42 to move, the adjusting rod 47 on the locking plate 42 drives the limiting wheel 49 to adjust the position of the movable control member 5. As a result, when the movable control member 5 drives the clamping member 6 to open and close and clamp the leaf spring, the opening and closing degree of the clamping member 6 can be gradually adjusted.
[0057] When the clamping member 6 gradually clamps the leaf springs of different sizes and clamps the last leaf spring, the locking plate 42 will move in the movable groove 44 to one end close to the clamping member 6. At this time, the locking block 45 will come into contact with the notch 443. Under the interference of the notch 443, the deflection amplitude of the locking block 45 on the locking plate 42 becomes larger, and the locking groove 452 on the locking block 45 will come into contact with the compression spring plate 46. The compression spring plate 46 limits the locking block 45. At this time, the locking block 45 no longer abuts against the card interface 441 in the movable groove 44, and then Driven by the return spring 48, the locking plate 42 can be moved and reset. The locking plate 42 moves in the moving groove 44 toward the end close to the transmission member 3. The locking block 45 contacts the slope 442 in the moving groove 44. Under the restriction of the slope 442, the locking block 45 deflects and resets on the locking plate 42. The compression spring plate 46 contacts the abutment groove 451 on the locking plate 42 again. Therefore, when the assembly quantity of each group of automobile leaf springs is completed during the clamping and transportation process, the locking plate 42 can be reset to the initial state.
[0058] When the driving motor 12 drives the driving disc 26 to rotate, the driving disc 26 rotates and drives the eccentric frame 27 to rotate around the driving disc 26 as the center of the circle. The other end of the eccentric frame 27 pulls the hinged tilting rod bracket 54 to move. The card wheel 53 on the movable frame 51 is the bracket of the tilting rod bracket 54. When the tilting rod bracket 54 is deflected by the eccentric frame 27, the other end of the tilting rod bracket 54 causes the pressure rod 55 to move up and down on the clamping support seat 1 through the positioning rod 57. Since the pressure rod 55 is connected to the clamping member 6, when the pressure rod 55 moves downward, it can drive the clamping member 6 to clamp the automobile leaf spring, and when the pressure rod 55 moves upward, it drives the clamping member 6 to loosen the automobile leaf spring, thereby driving the clamping member 6 to open and close through the mobile control member 5;
[0059] When the driving motor 12 drives the driving disc 26 to rotate one circle, the driving frame 21 rotates one circle synchronously, and the driving frame 21 drives the driving plate 23 to reciprocate, so that each time the driving disc 26 rotates to control the moving control member 5 to open and close the clamping member 6, the driving of the transmission member 3 and the locking member 4 can adjust the movable frame 51 to deflect on the outer wall of the clamping support seat 1, and each deflection of the movable frame 51 can drive the card wheel 53 provided at the bottom of the movable frame 51 to move, and when the card wheel 53 moves in the arc groove 58 on the tilting rod bracket 54, the position of the fulcrum of the tilting rod bracket 54 is changed, so that each time the tilting rod bracket 54 drives the pressure rod 55 to move up and down, the distance moved by the pressure rod 55 driven by the tilting rod bracket 54 will be shortened compared with the previous stroke distance;
[0060] When the lower pressure rod 55 moves downward, the lower pressure rod 55 will drive the control rod 61 to move downward on the mounting frame 14. The downward movement of the control rod 61 will drive the control plate 62 to move downward. The control plate 62 will drive the hinged connecting plate 64 to expand outward, thereby causing the hinged frame 63 close to the side of the control plate 62 to expand in the direction away from the control plate 62. The other hinged frame 63 plays a limiting role. At this time, the clamping plates 65 set on the two hinged frames 63 will expand outward, and the automobile leaf spring to be assembled will be clamped by the two relatively set clamping plates 65.
