Description

Technical Field

[0001] The utility model relates to the technical field of automobile plastic part assembly, and particularly relates to a pin pressing device for automobile plastic parts. Background Technique

[0002] With the increase of labor costs, more and more manufacturers develop automated equipment independently to assist production, so as to reduce labor costs and improve production efficiency at the same time.

[0003] In the process of industrial production, post-processing of products is required. For example, pins need to be pressed into products. For example, for a plastic connecting rod plate used in an automobile, pins need to be installed in the connecting holes of the plastic connecting rod plate. However, since there are strict requirements for the depth of the pins pressed into the connecting holes, currently, when manually pressing the pins into the connecting holes, the problem of under-pressing is likely to occur, that is, the problem that the depth of the pins pressed into the connecting holes is too low is likely to occur. However, after the problem of too low pressing depth occurs, due to the lack of prompt, it is not easy for the staff to find, which leads to the mixing of defective products and qualified products. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide a pin pressing device for automobile plastic parts, aiming to solve the problems in the background technique.

[0005] To achieve the above purpose, the technical solution of the utility model is as follows:

[0030] Combined with Figures 1 to 4 As shown, the present utility model discloses a pin pressing device for automotive plastic parts, including:

[0031] A working platform 1;

[0032] A profiling die 2, the profiling die 2 is placed on the working platform 1, the profiling die 2 has a through-hole part 21, and the through-hole part 21 is used to be vertically aligned with the connection hole of the automotive plastic part 10;

[0033] A downward pressing device 3, the downward pressing device 3 includes a driving device 31 and a pressing block 32. Both the driving device 31 and the pressing block 32 are located above the profiling die 2. The driving device 31 drives the pressing block 32 to reciprocate in the vertical direction for pressing the pin B into the through-hole part 21;

[0034] An infrared distance sensor 4, the distance sensor is arranged below the through-hole part 21 for detecting the distance between its sensing end and the bottom of the pin;

[0035] A control unit 5 and an alarm 6. The control unit 5 is electrically connected to the infrared distance sensor 4 and the alarm 6 respectively. When the infrared distance sensor 4 detects that the distance between its sensing end and the bottom of the pin is greater than a preset distance, the infrared distance sensor 4 generates an overpressure signal and transmits the overpressure signal to the control unit 5. After receiving the overpressure signal, the control unit 5 generates an alarm signal and transmits the alarm signal to the alarm 6. After receiving the alarm signal, the alarm 6 emits an alarm sound.

[0036] Compared with the prior art, the present utility model innovatively uses the downward pressing device 3 to replace manual work for pressing the pin, reducing the working intensity of the staff; and uses the infrared distance sensor 4 to monitor the pressing depth of the pin. When the infrared distance sensor 4 detects that the distance between its sensing end and the bottom of the pin is greater than a preset distance, the alarm 6 emits an alarm sound to remind the staff that the pressing depth of the pin is too small, effectively ensuring that the staff can timely discover defective products, re-press the defective products in time or separate the defective products from the qualified products in time, and centrally process the defective products subsequently.

[0037] It should be noted that in this application, before the pin pressing device works, it is necessary for the operator to manually place the automotive plastic part on the profiling die 2 and pre-insert the end of the pin into the through hole. At this time, the through hole and the end of the pin are tightly fitted to prevent the pin from falling off.

[0038] In one embodiment, since the automotive plastic part has multiple connection holes and multiple pins need to be installed, and the height positions of the multiple connection holes are different. To facilitate the equipment debugger to adjust the height of the pressing block 32; the pressing device 3 further includes a reference plate 33, the driving end of the driving device 31 is connected to the reference plate 33, and the pin pressing device for the automotive plastic part further includes an adjusting bar 34. The adjusting bar 34 passes through the reference plate 33 and is threadedly connected to the reference plate 33. The pressing block 32 is installed at one end of the adjusting bar 34 and is located below the reference plate 33. By adjusting the height position of the adjusting bar 34 relative to the reference plate 33, the position of the pressing block 32 can be adjusted, so that the equipment debugger can quickly adjust the height position of the pressing block 32 until the pressing block 32 can press the pin into the required depth, and then use a nut fastener to further fix the position of the adjusting bar 34 to prevent the adjusting bar 34 from loosening.

[0039] Furthermore, the pin pressing device for the automotive plastic part further includes a first limit post 71 and a second limit post; the first limit post and the second limit post are arranged vertically and aligned; wherein, the first limit post is installed on the reference plate 33 and protrudes below the reference plate 33, and the second limit post is installed on the working platform 1. During pressing, the air cylinder drives the reference plate 33 and the first limit post 71 to descend. When the first limit post 71 abuts against the second height limit post 72, the air cylinder can no longer drive the reference plate 33 and the first limit post 71 to descend. In this application, through the abutment of the first limit post 71 and the second height limit post 72, the extension stroke of the air cylinder can be kept constant, that is, the height position of the reference plate 33 can be fixed, and the lowest position of the pressing block 32 for each pressing is also fixed.

[0040] Furthermore, the first limit post is threadedly connected to the reference plate 33 to adjust the extension stroke of the air cylinder by adjusting the height position of the first limit post 71 relative to the reference plate 33, and cooperate with the position of the adjusting bar 34 to adjust the height position of the pressing block after the air cylinder extends. After adjusting the position of the first limit post, use a nut fastener to fix the position of the first limit post to prevent the first limit post from loosening.

[0041] Further, the driving device 31 is a cylinder, and the cylinder drives the reference plate 33 to reciprocate up and down; bearings 81 are installed at the four corners of the reference plate 33; each bearing 81 is inserted through a column 82, and the column 82 is installed on the working platform 1. Through the limiting effect of the four columns 82 on the reference plate 33, the reference plate 33 is kept horizontal, effectively avoiding the inclination of the pressing block 32 due to the inclination of the reference plate 33, ensuring that the pressing block 32 presses the pin in the vertical direction, and improving the assembly quality of the pin.

[0042] In one embodiment, to facilitate employees to store items, a storage room 9 is provided below the working platform 1.

[0043] The above description is an explanation of the present invention, not a limitation of the invention. The scope defined by the present invention is referred to the claims. Within the protection scope of the present invention, any form of modification can be made.

[0044] The present invention is not limited to the above embodiments. If various changes or deformations to the present invention do not depart from the spirit and scope of the present invention, and if these changes and deformations belong to the scope of the claims of the present invention and equivalent technical scope, then the present invention also intends to include these changes and deformations.
