Description

Technical Field

[0001] The utility model relates to the field of automobile seat slide rail processing, in particular to a steel ball blocking point extrusion device for an automobile seat slide rail. Background Art

[0002] Two steel ball stops need to be pressed out on the lower rail of the car seat. In the existing technology, workers usually manually feed the lower rail into the stamping machine. Since the car seat slide rails to be processed have different strokes and lengths, workers need to repeatedly switch the positioning mold during the actual processing process, which is easy to cause replacement errors, resulting in low work efficiency and long cycle time. In addition, when the steel ball stop point is close to the end face of the slide rail, the existing technology does not protect the lower rail during stamping, resulting in large deformation of the slide rail after stamping, poor dimensional stability of the stop point, and a high scrap rate of the slide rail, which can easily lead to quality problems such as reduced slide rail stroke, abnormal noise, inability to install the slide rail cover, and ball jumping. Summary of the Invention

[0003] The present invention aims to solve the deficiencies of the existing technology and develops a device for pressing out the steel ball stop points of a car seat slide rail.

DETAILED DESCRIPTION

[0016] 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.

A bracket 5; the first proximity switch 23 is fixedly arranged on the first bracket 5; the tray assembly 8 includes a tray 9 and a second cylinder 10; the second cylinder 10 is fixedly arranged on the base 1; the tray 9 is fixedly connected to the piston rod of the second cylinder 10; the pressure hole assembly 11 includes a guide rail 12, a slide 13, a servo motor 14, a second bracket 15, a threaded rod 16, a hydraulic cylinder 17, a slide rail protection frame 18, a hydraulic pump 19, a second proximity switch 24, a pressure head 26 and a pressure rod 27; the second bracket 1 5 is fixedly arranged on the base 1; the servo motor 14 is fixedly connected to the second bracket 15; the threaded rod 16 is fixedly connected to the servo motor 14; the guide rail 12 is fixedly connected to the second bracket 15; the slide 13 is slidably connected to the guide rail 12 and is threadedly connected to the threaded rod 16; the hydraulic cylinder 17 is fixedly arranged in the slide 13; the slide rail protection frame 18 is fixedly connected to the lower part of the slide 13; the pressure rod 27 is connected to the hydraulic cylinder 17; the pressure The head 26 is connected to the pressure rod 27; the second proximity switch 24 is fixedly arranged in the slide rail protection frame 18; the slide rail protection frame 18 has a support portion 25; the air pump 20 is respectively connected to the first cylinder 4, the pneumatic clamp 7 and the second cylinder 10 by pipeline; the hydraulic pump 19 is connected to the hydraulic cylinder 17 by pipeline; the buzzer 2 is fixedly arranged on the base 1; the buzzer 2, the servo motor 14, the hydraulic pump 19, the air pump 20, the first proximity switch 23 and the second proximity switch 24 are respectively electrically connected to the PLC.

[0018] When doing specific operations, such as Figure 2 As shown, the worker first places the car seat slide to be processed on the pallet 9, with the lower slide 21 upward and the upper slide 22 downward, and the upper slide 22 is moved downward close to the right side of the pallet 9 to complete the initial positioning; then, as shown in FIG. Figure 3As shown, the worker turns on the device, and the PLC controls the air pump 20 to work. The air pump 20 extends the piston rod of the second air cylinder 10, and the tray 9 lifts the lower slide rail 21 and the upper slide rail 22. When the tray 9 rises to the predetermined position, the first proximity switch 23 detects the tray 9 and sends a signal to the PLC. The PLC then controls the air pump 20 to make the pneumatic clamp 7 clamp the upper slide rail 22. If the tray 9 does not rise to the desired position and the first proximity switch 23 cannot detect the tray 9, the PLC controls the buzzer 2 to sound an alarm, prompting the worker to check the tray. If the tray detection is normal, as shown in FIG. Figure 4 As shown, the PLC controls the air pump 20 to extend the piston rod of the first cylinder 4, so that the push block 6 pushes the lower rail 21 to the right in the figure, so that the right end enters the rail protection frame 18; Figure 5 As shown, when the right end of the lower rail 21 correctly enters the rail protection frame 18, the second proximity switch 24 can detect it, and the second proximity switch 24 sends a signal to the PLC, and the PLC determines that the position of the lower rail 21 is correct; if the lower rail 21 does not correctly enter the rail protection frame 18, the second proximity switch 24 cannot detect it, and the PLC controls the buzzer 2 to sound an alarm, prompting the worker to check the right end of the lower rail 21; then, as shown Figures 6 to 8 As shown, the PLC controls the operation of the hydraulic pump 19, which in turn pushes the pressure rod 27 downward. The pressure head 26 at the lower end of the pressure rod 27 presses a three-sided opening on the lower rail 21, with the tail end still connected to the lower rail 21 to form a stop point 28. Because the bottom of the slide rail protection frame 18 has a support portion 25, and its frame supports both the left and right sides of the lower rail 21, the lower rail 21 is effectively prevented from deformation due to the force during the stop point pressing process, especially when the stop point is pressed near its end.

[0019] In the above process, the device completes the pressing out of the right blocking point of the lower rail 21; then, Figure 9 As shown, the PLC controls the servo motor 14 to rotate, and the slide 13 moves along the guide rail 12 to the left side of the figure. When it reaches the preset position, the left stop point of the lower slide rail 21 is pressed out in the manner described in the previous paragraph. Finally, as shown in FIG. Figure 10 As shown, the PLC controls the servo motor 14 to return the slide 13 to its initial position, and the PLC controls the air pump 20 to retract its piston rod. The worker manually retracts the lower slide rail 21, causing its right end to separate from the slide rail protection frame 18. When the second proximity switch 24 detects that the lower slide rail 21 is separated from the slide rail protection frame 18, it sends a signal to the PLC, which controls the air pump 20 to release the pneumatic clamp 7 and retract the piston rod of the second cylinder 10. The pallet 9 returns to the original position with the processed lower slide rail 21 and upper slide rail 22. Figure 2 The entire processing process is completed at the initial position shown in .

[0020] 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.
