[0013] Compared with the prior art, the present invention has the following beneficial effects: 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.

[0014] 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.

[0015] 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 return spring in a compressed state unable to drive the locking plate to reset.

[0016] In the present invention, the clamping plate moves in the moving groove toward one 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 clamping plate, and the compression spring plate abuts against the abutment groove on the clamping plate again. Therefore, during the process of clamping and transporting the automobile leaf springs, when the assembly quantity of each group of automobile leaf springs is completed, the clamping plate can be reset to the initial state, and each group of automobile leaf springs can be repeatedly clamped and transported.

[0017] In the present invention, the clamping wheel on the moving frame is the bracket of the tilting rod bracket. When the tilting rod bracket is deflected under the drive of the eccentric frame, the other end of the tilting rod bracket will make the pressure rod 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.

[0018] In the present invention, when the clamping wheel moves in the arc groove on the tilting rod bracket, the position of the fulcrum of the tilting rod bracket will be changed, so that each time the tilting rod bracket drives the pressure rod to move up and down reciprocatingly, the distance moved by the tilting rod bracket driving the pressure rod will be shorter than the previous stroke distance. The shortened stroke distance of the pressure rod will reduce the opening and closing degree of the clamping member. 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 member clamps a single leaf spring, the opening and closing degree of the clamping member can be adjusted with the cooperation of the transmission member, the locking member and the moving control member, 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

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technical personnel in this field without creative work are within the scope of protection of the present invention.

[0022] See also Figures 1 to 11 The present invention provides a technical solution: an automated automobile leaf spring assembly platform, comprising a clamping support seat 1, a motor seat 11 is fixedly connected to the side wall of the clamping support seat 1, a driving motor 12 is fixedly connected to the motor seat 11, and the main shaft of the driving motor 12 is arranged toward the direction of the clamping support seat 1; It also includes a driving rotating member 2, which is arranged on the main shaft of the driving motor 12. The side wall of the clamping support seat 1 facing the motor seat 11 is fixedly connected to a limiting frame 13, and the driving rotating member 2 is slidably matched with the limiting frame 13. 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 transmission-matched with the driving rotating member 2, and The transmission member 3 is in transmission cooperation with the locking member 4. A moving control member 5 is also rotatably provided on the side wall of the clamping support seat 1 facing the motor seat 11. The moving control member 5 is in transmission cooperation with the driving rotating member 2, and the moving control member 5 and the locking member 4 are in abutment cooperation. A mounting frame 14 is fixed vertically downward on the clamping support seat 1. A clamping member 6 is provided on the mounting frame 14. The clamping member 6 and the mounting frame 14 are in sliding cooperation. The other side of the moving control member 5 away from the driving rotating member 2 is connected to the clamping member 6. The driving motor 12 drives the driving rotating member 2 to rotate, 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, and the moving control member 5 moves away from the other side of the driving rotating member 2, which causes the clamping end of the clamping member 6 to 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 the clamping of leaf springs of different specifications.

[0023] In this embodiment, the driving rotating member 2 includes a driving frame 21 arranged 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 arranged on the top of the limiting frame 13, and a vertical groove 24 is arranged vertically on the driving plate 23, and the fixing rod 22 on the driving frame 21 is located in the vertical groove 24, and a driving rack 25 is fixedly arranged on the inner wall of the driving plate 23 on the side facing the clamping support seat 1, and the driving rack 25 is in transmission cooperation with the transmission member 3; The transmission member 3 includes a transmission rod 31 rotatably arranged on the side wall of the clamping support seat 1, a transmission gear 32 is fixedly connected to the transmission rod 31, and the transmission gear 32 is meshed with the driving rack 25. An inner ratchet disk 33 is also fixedly connected to the transmission rod 31, a notch 34 is provided 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 arranged between the pawl 35 and the notch 34. An outer ratchet disk 37 is also rotatably arranged on the outer wall of the inner ratchet disk 33, and ratchet teeth 38 contacting the pawl 35 are arranged 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 cooperates with the locking member 4 in transmission. 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 fixing rod 22 at the other end of the driving frame 21 to rotate with the main shaft of the driving motor 12. Because the fixing rod 22 is arranged in the vertical slot 24 on the driving frame 21, when the fixing rod 22 rotates, the driving frame 21 will reciprocate on the limiting 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 disk 33. The ratchet pawl 35 on the inner ratchet disk 33 is embedded in the outer ratchet disk 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. Through the reciprocating movement of the driving plate 23, the intermittent rotation of the outer ratchet plate 37 can be intermittently driven. 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.

[0024] 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, a moving gear rod 43 is fixedly connected to the locking plate 42, the moving gear rod 43 is arranged toward the direction of the transmission member 3, and the moving gear rod 43 is meshed with the fixed gear ring 39 on the outer ratchet disc 37; The card base 41 is provided with a moving groove 44, and the moving groove 44 is provided with a plurality of card interfaces 441 arranged at equal intervals, and the plurality of card interfaces 441 are arranged in a wave shape, and the two ends of the moving groove 44 are respectively arranged toward the transmission member 3 and the clamping member 6, and the end of the moving groove 44 arranged toward the transmission member 3 is provided with an inclined slope 442, and the end of the moving groove 44 arranged toward the clamping member 6 is provided with a notch 443; 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 elastically arranged 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; An adjusting rod 47 is fixedly connected to the side wall of the locking plate 42 at the side opposite to the moving gear rod 43. The adjusting rod 47 is slidably matched 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. When the inner ratchet disc 33 rotates clockwise to drive the outer ratchet disc 37 to rotate, the outer ratchet disc 37 will drive the movable gear rod 43 to move toward the direction of 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 make 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 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 a compressed state cannot drive the locking plate 42 to reset. Each time the outer ratchet disc 37 rotates to drive 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 moving control member 5, so that when the moving control member 5 drives the clamping member 6 to open and close to clamp the leaf spring, the opening and closing degree of the clamping member 6 can be gradually adjusted; 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 contact the notch 443. The abutment frame in the notch 443 makes the deflection of the locking block 45 on the clamping plate 65 larger, and the locking groove 452 on the locking block 45 will contact the compression spring plate 46. The compression spring plate 46 limits the locking block 45. At this time, the locking block 45 is no longer in contact with the card interface 441 in the moving groove 44, and then driven by the reset spring 48, The clamping plate 65 can be moved and reset, and the clamping plate 65 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 clamping plate 65, and the compression spring plate 46 abuts against the abutment groove 451 on the clamping plate 65 again, so that during the process of clamping and transporting the automobile leaf springs, when the assembly quantity of each group of automobile leaf springs is completed, the clamping plate 65 can be reset to the initial state, and each group of automobile leaf springs can be repeatedly clamped and transported.

[0025] In this embodiment, the mobile control member 5 includes a mobile frame 51 arranged on the outer wall of the clamping support seat 1 facing the motor seat 11, and the mobile 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 mobile frame 51, and the limiting wheel 49 on the adjusting rod 47 is in the connecting groove 52. The end of the mobile 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 arranged 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 further comprises a tilting rod bracket 54 hingedly arranged on the eccentric frame 27, a pressure rod 55 is slidably arranged on the clamping support seat 1 above the clamping member 6, a vertically arranged through slot 56 is provided on the pressure rod 55, a positioning rod 57 is arranged horizontally and vertically in the through slot 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 further provided with an arc slot 58 arranged in a semi-arc shape, the clamping wheel 53 on the mobile frame 51 is located in the arc slot 58, and the bottom of the pressure rod 55 is fixedly connected to the clamping member 6; When the driving motor 12 drives the driving disk 26 to rotate, the rotation of the driving disk 26 will drive the eccentric frame 27 to rotate around the driving disk 26 as the center of the circle, and the other end of the eccentric frame 27 will pull the hinged tilting rod bracket 54 to move, and the clamping wheel 53 on the moving frame 51 is the bracket of the tilting rod bracket 54. When the tilting rod bracket 54 is deflected under the drive of the eccentric frame 27, the other end of the tilting rod bracket 54 will make the pressure rod 55 reciprocate 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; When the driving motor 12 drives the driving disk 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 disk 26 rotates to control the moving control member 5 to open and close the clamping member 6, the moving frame 51 can be adjusted to deflect on the outer wall of the clamping support seat 1 under the drive of the transmission member 3 and the locking member 4, and each deflection of the moving frame 51 can drive the card wheel 53 set 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 will be 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 driven to move the pressure rod 55 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 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 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 a 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.

[0026] 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 arranged 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 arranged between the articulated frame 63 close to the control plate 62 and the control plate 62, and a clamping plate 65 is hingedly arranged at the other end of the two articulated frames 63 away from the mounting frame 14; 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 articulated frame 63 close to the side of the control plate 62 to expand in the direction away from the control plate 62. The other articulated frame 63 plays a limiting role. At this time, the clamping plates 65 arranged on the two articulated 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.

[0027] 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: like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 , Fig.11 As shown in the figure: 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 fixing rod 22 at the other end of the driving frame 21 to rotate with the main shaft of the driving motor 12. Because the fixing rod 22 is set in the vertical groove 24 on the driving frame 21, when the fixing rod 22 rotates, the driving frame 21 will reciprocate on the limiting frame 13 under the restriction of the vertical groove 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 32 ​​rotate clockwise. The wheel disc 33 rotates, and 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 will be 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, and the reciprocating movement of the driving plate 23 can intermittently drive the intermittent rotation of the outer ratchet disc 37. When the inner ratchet disc 33 rotates clockwise to drive 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 make 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 abut against the abutment groove 451 on the locking block 45, thereby restricting the locking block 45 in the card interface 441. Each time the outer ratchet disc 37 rotates to drive 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 moving control member 5, so that when the moving control member 5 drives the clamping member 6 to open and close to clamp the leaf spring, the opening and closing degree of the clamping member 6 can be gradually adjusted; 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 contact the notch 443. The abutment frame in the notch 443 makes the deflection of the locking block 45 on the clamping plate 65 larger, and the locking groove 452 on the locking block 45 will contact the compression spring plate 46. The compression spring plate 46 limits the locking block 45. At this time, the locking block 45 is no longer in contact with the card interface 441 in the movable groove 44, and then Driven by the reset spring 48, the clamping plate 65 can be moved and reset, and the clamping plate 65 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 clamping plate 65, and the compression spring plate 46 is abutted against the abutment groove 451 on the clamping plate 65 again, so that when the automobile leaf spring is clamped and transported, the clamping plate 65 can be reset to the initial state when the assembly quantity of each group of automobile leaf springs is completed; When the driving motor 12 drives the driving disk 26 to rotate, the rotation of the driving disk 26 will drive the eccentric frame 27 to rotate around the driving disk 26 as the center of the circle, and the other end of the eccentric frame 27 will pull the hinged tilting rod bracket 54 to move, and the clamping wheel 53 on the moving frame 51 is the bracket of the tilting rod bracket 54. When the tilting rod bracket 54 is deflected under the drive of the eccentric frame 27, the other end of the tilting rod bracket 54 will make the pressure rod 55 reciprocate 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; When the driving motor 12 drives the driving disk 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 disk 26 rotates to control the moving control member 5 to open and close the clamping member 6, the driving 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 set 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 will be 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 tilting rod bracket 54 will be shortened compared with the previous travel distance; 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 control rod 61 moves downward and drives the control plate 62 to move downward. The control plate 62 drives the hinged connecting plate 64 to expand outward, thereby making the articulated frame 63 close to the side of the control plate 62 expand in the direction away from the control plate 62. The other articulated frame 63 plays a limiting role. At this time, the clamping plates 65 arranged on the two articulated frames 63 will expand outward, and the automobile leaf spring to be assembled will be clamped by the two relatively arranged clamping plates 65.
