[0003] In the production process of automobile rearview mirror commutators, the current process is to install the support strip in the ring frame on the rearview mirror body after flattening and extrusion. However, in actual operation, since the ring frame is circular in shape at the beginning, when the ring frame is placed for flattening and extrusion, there is no limiting mechanism on the ring frame, which makes the position of the ring frame unstable and prone to deviation, affecting its subsequent flattening and extrusion molding effect.

[0012] Preferably, a first wedge block is fixedly connected to the side wall of the rectangular frame close to the bidirectional lead screw.

A second wedge block is fixedly connected to the side wall of the second plate away from the L-shaped block. The side wall of the first wedge block cooperates with the side wall of the second wedge block.

[0013] Preferably, an ejection mechanism for ejecting the ring frame after it is supported and flattened is provided on the workbench.

When the second wedge block is in contact with the first wedge block, the first wedge block drives the rectangular frame to move away from the second wedge block under the squeezing action of the second wedge block. The movement of the rectangular frame will simultaneously drive the limit column to move, ensuring that when the ring frame is initially flattened, the position of the ring frame is still limited to prevent it from deviation.

[0020] 3. When the second wedge block moves and separates from the first wedge block, it means that the extrusion plate fits tightly against the ring frame. At this time, under the action of multiple first springs, the rectangular frame will drive the rectangular rod and the limit column to slide to their original position, preventing the limit column from always contacting the side wall of the ring frame and affecting its final flattening and forming effect.

DETAILED DESCRIPTION

[0029] 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 technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Reference Figure 1 - Figure 7 A car rearview mirror ring support flattening installation device comprises a workbench 1 and an extrusion mechanism, the extrusion mechanism comprises two first through grooves 2 opened at the upper end of the workbench 1, the inner walls of the two first through grooves 2 are respectively slidably connected to two L-shaped blocks 3, the side walls of the two L-shaped blocks 3 close to each other are fixedly connected to extrusion plates 4, and the side walls of the extrusion plates 4 away from the L-shaped blocks 3 are in an arc shape, the lower end of the workbench 1 is rotatably connected to a bidirectional lead screw 5 through two support plates, the side walls of the bidirectional lead screw 5 are respectively threadedly connected to the side walls of the two L-shaped blocks 3, one of the support plate side walls is fixedly connected to a motor 6, and the movable end of the motor 6 is fixedly connected to one end of the bidirectional lead screw 5.

[0031] When the motor 6 rotates clockwise, the bidirectional screw 5 rotates clockwise. At this time, the two L-shaped blocks 3 approach each other, driving the two extrusion plates 4 to approach each other, flattening the ring frame for easy installation. When the motor 6 rotates counterclockwise, the bidirectional screw 5 rotates counterclockwise. At this time, the two L-shaped blocks 3 move away from each other, causing the two extrusion plates 4 to move away from each other, and the ring frame is loosened.

[0032] The anti-bias mechanism includes two second through slots 7 opened at the upper end of the workbench 1, the second through slots 7 are vertically arranged to the first through slots 2, the inner walls of the second through slots 7 are slidably connected with rectangular rods 8, the upper ends of the rectangular rods 8 are fixedly connected with limiting columns 9, the lower end of the workbench 1 near the second through slots 7 is fixedly connected with two first plates 10, the side walls of the two first plates 10 are slidably connected with L-shaped plates 11, a rectangular frame 12 is fixedly connected between the side walls of the two L-shaped plates 11 close to each other, the side walls of the L-shaped plates 11 are elastically connected to the side walls of the first plates 10 through first springs 13, the side walls of the rectangular rods 8 are slidably connected to the side walls of the rectangular frame 12, and the side walls of the rectangular rods 8 are elastically connected to the inner walls of the rectangular frame 12 through multiple second springs 14.

[0033] It should be noted that the stiffness coefficient of the first spring 13 is much greater than the stiffness coefficient of the second spring 14 , so that during the movement of the rectangular rod 8 , the force exerted on the second spring 14 will not drive the rectangular frame 12 to move.

[0034] When the ring frame is placed on the workbench 1, the two limit columns 9 can be pulled closer to each other so that the two limit columns 9 are located inside the ring frame, and then the two limit columns 9 are released. At this time, under the elastic force of multiple second springs 14, the two rectangular rods 8 drive the two limit columns 9 to fit against the inner wall of the ring frame to limit the position of the ring frame, thereby avoiding the unstable position of the ring frame in the prior art, which is prone to deviation during flattening installation, affecting the subsequent flattening extrusion molding effect.

[0035] A limiting mechanism for limiting the position of the rectangular rod 8 is provided in the rectangular frame 12, and the limiting mechanism includes two grooves 15 opened on the inner wall of the rectangular frame 12, and a plurality of electromagnetic push rods 16 are fixedly connected to the inner wall of the groove 15, and the movable ends of the plurality of electromagnetic push rods 16 are commonly fixedly connected to a first friction plate 17, and a second friction plate 18 cooperating with the first friction plate 17 is fixedly connected to the side wall of the rectangular rod 8, and the electromagnetic push rod 16 is electrically connected to the motor 6 through a diode.

[0036] The electromagnetic push rod 16 is an action actuator that uses the working characteristics of the electromagnet to realize the linear reciprocating motion of the push rod. It has the advantages of large thrust and high sensitivity. When the motor 6 rotates clockwise, the diode allows the current on the motor 6 that passes through the electromagnetic push rod 16 to pass, and then the electromagnetic push rod 16 is energized and extended, so that the first friction plate 17 and the second friction plate 18 fit tightly together, and the position of the rectangular rod 8 is fixed. When the motor 6 rotates counterclockwise, the diode does not allow the current on the motor 6 that passes through the electromagnetic push rod 16 to pass, and then the electromagnetic push rod 16 is de-energized and retracted, so that the first friction plate 17 and the second friction plate 18 are separated, and the rectangular rod 8 is loosened.

[0037] The side wall of the rectangular frame 12 close to the bidirectional lead screw 5 is fixedly connected to a first wedge block 19, and the side walls of the two L-shaped blocks 3 away from each other are fixedly connected to a second plate 20 (such as Figure 2 As shown in the figure, a second wedge block 21 is fixedly connected to the side wall of the second plate 20 away from the L-shaped block 3, and the side wall of the first wedge block 19 cooperates with the side wall of the second wedge block 21.

[0038] As Figure 2 and Figure 3 shown, when the motor 6 rotates clockwise, at this time the two pressing plates 4 approach each other to flatten the ring frame. During this process, the two L-shaped blocks 3 drive the two second wedge blocks 21 to move towards the two first wedge blocks 19 respectively through the two second plates 20. When the second wedge block 21 fits with the first wedge block 19, at this time, under the extrusion of the second wedge block 21, the first wedge block 19 drives the rectangular frame 12 to move away from the second wedge block 21. At this time, since the electromagnetic push rod 16 is energized and extended to fix the position of the rectangular rod 8, the movement of the rectangular frame 12 will synchronously drive the limit post 9 to move, ensuring that when the ring frame is initially flattened, the position of the ring frame is still limited to prevent it from running off;

[0039] When the second wedge block 21 moves and separates from the first wedge block 19, it means that the pressing plates 4 are in close contact with the ring frame. At this time, under the action of multiple first springs 13, the rectangular frame 12 will drive the rectangular rod 8 and the limit post 9 to slide back to their original positions, preventing the limit post 9 from always contacting the side wall of the ring frame and affecting its final flattened forming effect.

[0040] When the motor 6 rotates counterclockwise, the two pressing plates 4 separate from the ring frame, and the electromagnetic push rod 16 is powered off and contracts to release the rectangular rod 8. At this time, under the action of multiple second springs 14, the rectangular rod 8 makes the limit post 9 fit with the side wall of the ring frame to prevent the position of the ring frame from changing.

[0041] A jacking mechanism for jacking out the flattened and installed ring frame is provided on the workbench 1. The jacking mechanism includes a cavity 22 opened in the workbench 1. The inner wall of the cavity 22 is hermetically and slidably connected with a slide plate 23. The upper end of the slide plate 23 is fixedly connected with a plurality of ejector rods 24. The ejector rods 24 penetrate through the side wall of the workbench 1. The lower end of the slide plate 23 is elastically connected with the bottom of the cavity 22 through a plurality of third springs 25.

[0042] The side wall of the workbench 1 is fixedly connected with an oil storage frame 26 through a bracket. The inner wall of the oil storage frame 26 is hermetically and slidably connected with a third plate 27. Hydraulic oil is provided in the enclosed space formed by the side wall of the third plate 27 and the inner wall of the oil storage frame 26. The inner wall of the oil storage frame 26 is communicated with the inner wall of the cavity 22 through a connecting pipe 28. A U-shaped plate 29 is fixedly connected to the inner wall of the oil storage frame 26 near the frame opening. A ball screw 30 is rotatably connected to the side wall of the U-shaped plate 29. A fourth plate 31 is threadedly connected to the side wall of the ball screw 30. The side wall of the fourth plate 31 is fixedly connected with the side wall of the third plate 27 through a plurality of connecting rods.

[0043] A torsion spring 32 is sleeved on the side wall of the ball screw 30 located inside the U-shaped plate 29 . One end of the torsion spring 32 is fixedly connected to the side wall of the ball screw 30 , and the other end of the torsion spring 32 is fixedly connected to one of the inner side walls of the U-shaped plate 29 .

[0044] The ball screw 30 is provided with a rotating mechanism, which includes a one-way bearing 33. The inner ring side wall of the one-way bearing 33 is fixedly connected to the side wall of the ball screw 30. The outer ring side wall of the one-way bearing 33 is fixedly connected to a gear 34. One of the side walls of the L-shaped block 3 is fixedly connected to a toothed plate 35, and the toothed plate 35 meshes with the gear 34 during movement.

[0045] like Figure 2 , Figure 6 and Figure 7 As shown, when the two L-shaped blocks 3 are close to each other, the toothed plate 35 will drive the gear 34 to rotate counterclockwise during the movement (as shown in FIG. Figure 7 As shown in FIG. 1 ), the outer ring of the one-way bearing 33 does not drive the inner ring to rotate. When the two L-shaped blocks 3 move away from each other, the toothed plate 35 drives the gear 34 to rotate clockwise during the movement (as shown in FIG. 1 ). Figure 7 As shown in the figure, the outer ring of the one-way bearing 33 drives its inner ring to rotate, indicating that the two extrusion plates 4 are completely separated from the ring frame at this time. At this time, the inner ring of the one-way bearing 33 drives the ball screw 30 to rotate clockwise, and the fourth plate 31 drives the third plate 27 to move through multiple connecting rods, and squeezes the hydraulic oil in the oil storage frame 26 into the cavity 22 through the connecting pipe 28, driving the slide plate 23 and multiple push rods 24 to move upward, and lift up the flattened ring frame to facilitate its removal;

[0046] During this process, the torsion spring 32 will rotate to store elastic potential energy. When the tooth plate 35 moves and separates from the gear 34, the elastic potential energy is released from the torsion spring 32, driving the ball screw 30 to rotate counterclockwise, so that the fourth plate 31 drives the third plate 27 to move to its original position through multiple connecting rods, and then the hydraulic oil in the cavity 22 enters the oil storage frame 26 through the connecting pipe 28, so that the slide plate 23 and multiple push rods 24 move down to their original positions to facilitate the next operation.

[0047] When flattening and installing the support strip for the automobile rearview mirror ring frame, first pull the two limit posts 9 closer to each other, put the ring frame on the workbench 1, so that the two limit posts 9 are located inside the ring frame, and then loosen the two limit posts 9. At this time, under the elastic force of the plurality of second springs 14, the two rectangular rods 8 drive the two limit posts 9 to fit with the inner wall of the ring frame to limit the position of the ring frame;

[0048] Then the driving motor 6 rotates clockwise, and the bidirectional lead screw 5 rotates clockwise. At this time, the two L-shaped blocks 3 approach each other, driving the two extrusion plates 4 to approach each other, and flattening the ring frame;

[0049] When the motor 6 rotates clockwise, the diode allows the current on the motor 6 to pass through the electromagnetic push rod 16, and then the electromagnetic push rod 16 is energized and extended, so that the first friction plate 17 and the second friction plate 18 are closely fitted, and the position of the rectangular rod 8 is fixed;

[0050] And in this process, the two L-shaped blocks 3 drive the two second wedge blocks 21 to move toward the two first wedge blocks 19 respectively through the two second plates 20. When the second wedge blocks 21 are fitted with the first wedge blocks 19, the first wedge blocks 19 drive the rectangular frame 12 to move away from the second wedge blocks 21 under the extrusion of the second wedge blocks 21. At this time, since the electromagnetic push rod 16 is energized and extended to fix the position of the rectangular rod 8, the movement of the rectangular frame 12 will synchronously drive the limit column 9 to move, ensuring that when the ring frame is initially flattened, the position of the ring frame is still limited to prevent it from running off.

[0051] When the second wedge block 21 moves and separates from the first wedge block 19, it means that the extrusion plate 4 is tightly fitted to the ring frame. At this time, under the action of the plurality of first springs 13, the rectangular frame 12 will drive the rectangular rod 8 and the limiting column 9 to slide to the original position, so as to prevent the limiting column 9 from always contacting the side wall of the ring frame and affecting its final flattening and forming effect.

[0052] After the ring frame is flattened, the driving motor 6 rotates counterclockwise, and the bidirectional lead screw 5 rotates counterclockwise, at which time the two L-shaped blocks 3 move away from each other, so that the two extrusion plates 4 move away from each other, and the ring frame is loosened;

[0053] At this time, the diode does not allow the current on the motor 6 to pass through the electromagnetic push rod 16, and then the electromagnetic push rod 16 is de-energized and retracted, so that the first friction plate 17 and the second friction plate 18 are separated, and the rectangular rod 8 is loosened. At this time, under the action of the plurality of second springs 14, the limiting column 9 of the rectangular rod 8 fits with the side wall of the ring frame to prevent the position of the ring frame from changing;

[0054] When the two L-shaped blocks 3 move away from each other, the toothed plate 35 drives the gear 34 to rotate clockwise during the movement, and the outer ring of the one-way bearing 33 drives its inner ring to rotate, indicating that the two extrusion plates 4 are completely separated from the ring frame. At this time, the inner ring of the one-way bearing 33 drives the ball screw 30 to rotate clockwise, and the fourth plate 31 drives the third plate 27 to move through multiple connecting rods, and squeezes the hydraulic oil in the oil storage frame 26 into the cavity 22 through the connecting pipe 28, driving the slide plate 23 and multiple push rods 24 to move upward, and lift up the flattened ring frame to facilitate its removal, thereby speeding up the installation of the support bar;

[0055] During this process, the torsion spring 32 will rotate to store elastic potential energy. When the tooth plate 35 moves and separates from the gear 34, the elastic potential energy is released from the torsion spring 32, driving the ball screw 30 to rotate counterclockwise, so that the fourth plate 31 drives the third plate 27 to move to its original position through multiple connecting rods, and then the hydraulic oil in the cavity 22 enters the oil storage frame 26 through the connecting pipe 28. Under the action of multiple third springs 25, the slide plate 23 and multiple push rods 24 move down to their original positions to facilitate the next operation.

[0056] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
