Description

Technical Field

[0001] The utility model relates to the field of automobile seat assembly, in particular to a device for driving a thrust piece of a synchronization rod of an automobile seat. Background Art

[0002] Thrust plates need to be driven into both ends of the synchronization rod of the car seat to prevent the synchronization rod from moving horizontally and slipping off the seat. The commonly used synchronization rods and thrust plates are both made of metal. The cross-section of the synchronization rod is four-sided, while the thrust plate usually has six openings. In the prior art, the angle between the thrust plate and the synchronization rod when being driven in is random. As long as the force of the driving mechanism is strong enough, the thrust plate can be driven into the outer end of the synchronization rod. However, in many cases, the thrust plate that has been driven in with great force has already undergone plastic deformation. Although it is stuck on the outer end of the synchronization rod, the clamping force on the synchronization rod can no longer meet the pull force requirement of the synchronization rod. Summary of the Invention

[0003] In view of the deficiencies of the existing technology, the utility model develops a device for driving a thrust piece of a synchronous rod of a car seat. The technical solution adopted by the utility model is: a device for driving a thrust piece of a synchronous rod of a car seat, characterized in that it includes a workbench 1, a thrust piece driving assembly 2, a synchronous rod clamp 12, a buzzer 19 and a PLC; the thrust piece driving assembly 2 and the synchronous rod clamp 12 are respectively fixedly arranged on the workbench 1; the thrust piece driving assembly 2 includes a guide rail 3, a punching electric cylinder 4, a force sensor 5, a sliding plate 6, a locking electric cylinder 7, a rotating shaft seat 8, a push rod electric cylinder 9, a punching head 10, a rotating shaft 11 and a push rod 13; the guide rail 3 and the punching electric cylinder 4 are fixedly arranged on the workbench 1; the sliding plate 6 is slidably connected to the guide rail 3; one end of the force sensor 5 is fixedly connected to the sliding plate 6, and the other end thereof is fixedly connected to the piston rod of the punching electric cylinder 4; the rotating shaft seat 8 is fixedly arranged on the sliding plate 6; the shaft The bearing 16 is arranged in the rotating shaft seat 8; the rotating shaft 11 is placed in the bearing 16 and inserted into the rotating shaft seat 8; the outer end circumference of the rotating shaft 11 is provided with a shifting post 18; the push rod electric cylinder 9 is fixedly arranged on the rotating shaft seat 8, and the end of its piston rod is fixedly connected to the pushing rod 13; the pushing rod 13 has an upper column 14 and a lower column 15; the shifting post 18 is placed between the upper column 14 and the lower column 15; the punching head 10 is fixedly connected to the outer end of the rotating shaft 11; the locking electric cylinder 7 is fixedly arranged on the rotating shaft seat 8, and its piston rod is inserted downward into the rotating shaft seat 8 and can press the bearing 16; the magnetic ring 17 is fixedly arranged in the punching head 10; the punching electric cylinder 4, force sensor 5, locking electric cylinder 7, push rod electric cylinder 9 and buzzer 19 are electrically connected to the PLC respectively.

[0004] The benefits of the present invention are as follows: since a force sensor is provided between the punching electric cylinder and the sliding plate, when the angle between the thrust plate and the outer end of the synchronization rod does not match, a greater force is required to force it in, and the force sensor sends a signal to the PLC, which controls the punching electric cylinder to stop punching and controls the push rod electric cylinder to push the punching head to rotate, thereby driving the thrust plate to rotate a certain angle, so that the angle between the thrust plate and the outer end of the synchronization rod matches, effectively avoiding the plastic deformation of the thrust plate caused by forcibly inserting it, thereby reducing the pulling force of the synchronization rod, and thus improving the stability of product quality.

DETAILED DESCRIPTION

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. The specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0020] like Figures 1 to 3 As shown, the utility model is a car seat synchronization rod thrust plate driving device comprising: a workbench 1, a thrust plate driving assembly 2, a synchronization rod clamp 12, a buzzer 19 and a PLC; the thrust plate driving assembly 2 and the synchronization rod clamp 12 are respectively fixedly arranged on the workbench 1; the thrust plate driving assembly 2 comprises a guide rail 3, a sheet-beating electric cylinder 4, a force sensor 5, a sliding plate 6, a locking electric cylinder 7, a rotating shaft seat 8, a push rod electric cylinder 9, a sheet-beating head 10, a rotating shaft 11 and a push rod 13; the guide rail 3 and the sheet-beating electric cylinder 4 are fixedly arranged on the workbench 1; the sliding plate 6 is slidably connected to the guide rail 3; one end of the force sensor 5 is fixedly connected to the sliding plate 6, and the other end thereof is fixedly connected to the piston rod of the sheet-beating electric cylinder 4; the rotating shaft seat 8 is fixedly arranged on the sliding plate 6; the bearing 16 is set In the rotating shaft seat 8; the rotating shaft 11 is placed in the bearing 16 and inserted into the rotating shaft seat 8; the outer end circumference of the rotating shaft 11 is provided with a shifting post 18; the push rod electric cylinder 9 is fixedly arranged on the rotating shaft seat 8, and the end of its piston rod is fixedly connected to the pushing rod 13; the pushing rod 13 has an upper column 14 and a lower column 15; the shifting post 18 is placed between the upper column 14 and the lower column 15; the punching head 10 is fixedly connected to the outer end of the rotating shaft 11; the locking electric cylinder 7 is fixedly arranged on the rotating shaft seat 8, and its piston rod is inserted downward into the rotating shaft seat 8 and can press the bearing 16; the magnetic ring 17 is fixedly arranged in the punching head 10; the punching electric cylinder 4, force sensor 5, locking electric cylinder 7, push rod electric cylinder 9 and buzzer 19 are electrically connected to the PLC respectively.

[0021] When doing specific operations, such as Figures 4 to 6As shown, the worker first clamps the synchronization rod 20 in the synchronization rod clamp 12, and puts the thrust plate 21 into the punching head 10. The magnetic ring 17 is fixed in the punching head 10 to attract the thrust plate 21; then the worker operates the equipment to start the machine, and the PLC controls the piston rod of the locking cylinder 7 to press down on the rotating shaft 11 in the rotating shaft seat 8 to prevent the rotating shaft 11 from unnecessary rotation. The above is the preparatory work before inserting the thrust plate.

[0022] like Figures 7 to 10 As shown, the worker continues to operate the equipment, and the PLC controls the piston rod of the punching cylinder 4 to move to the left in the figure. The piston rod pushes the sliding plate 6 along the guide rail 3 to move to the left in the figure through the force sensor 5. The punching head 10 completes the driving of the thrust plate 21. Figure 8 As shown, the cross section of the synchronization rod 20 is a quadrangular; Figure 9 As shown, the thrust plate 21 has six openings. Since the thrust plate 21 is installed in the punching head 10 during the aforementioned preparations, the angles between the six openings and the four edges of the synchronization rod 20 are random; Figure 10 As shown in the figure, when the angle between the two is appropriate, the driving process can be completed under the specified force, and the force sensor 5 does not need to send a signal to the PLC. At this time, the thrust plate is basically in elastic deformation, ensuring the clamping force on the synchronization rod. The thrust plate's good clamping force on the synchronization rod ensures the required pulling force of the synchronization rod.

[0023] like Figure 11 As shown, when the six-piece opening of the thrust plate 21 and the four-edge angle of the synchronization rod 20 are not suitable, the force detected by the force sensor 5 has exceeded the set value during the insertion of the thrust plate 21, which sends a signal to the PLC, which controls the piston rod of the electric cylinder to retract, avoiding the thrust plate from being forcibly inserted and causing its plastic deformation. Figure 12 As shown, the PLC then controls the piston rod of the locking electric cylinder 7 to retract, and controls the piston rod of the push rod electric cylinder 9 to drive the push rod 13 to move downward. The upper column 14 pushes the dial column 18 to rotate the rotating shaft 11 about 15° clockwise, and the thrust plate 21 in the punching head 10 also rotates 15° clockwise. The PLC then controls the locking electric cylinder 7 to press the rotating shaft 11, and performs the punching process again according to the above operation.

[0024] like Figure 12 and Figure 13 As shown, generally, for a quadrangular synchronization rod 20, the thrust plate 21 can be driven in by rotating it clockwise by 15° under a prescribed force.

[0025] After the synchronization rod is driven into the thrust plate, the PLC controls the above components to operate in reverse and restore to their initial positions.

[0026] If the thrust plate still cannot be driven in under the specified force after rotation, the PLC controls the buzzer to sound an alarm, prompting the worker to check whether the thrust plate meets the quality requirements.

[0027] The above is only a preferred embodiment of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
