Description

Technical Field

[0001] This utility model relates to the field of automotive throttle valves, and in particular to a hot riveting device for a throttle valve dust cover. Background Technology

[0002] During the manufacturing process of the throttle body, various cables, mounting brackets, and PCB boards need to be added to the inside of the dust cover body to form a dust cover assembly. In this dust cover assembly, the PCB board is connected to the mounting bracket, and the mounting bracket is connected to the dust cover body.

[0003] Currently, single rivets are often used to connect PCB boards to fixed brackets. However, using rivets for fixing not only incurs the cost of rivets, but the riveting process can also easily leave indentations on the PCB.

[0004] Therefore, after investigation and research, we considered alternative methods to connect the PCB board and the mounting bracket, such as thermal riveting. Our idea is to add insertion posts to the plastic mounting bracket and insertion holes to the PCB board. Then, after the insertion posts are inserted into the holes, thermal riveting deforms the upper end of the insertion posts, thus connecting the PCB board and the mounting bracket. Therefore, we urgently need to develop a thermal riveting device to quickly and effectively achieve the above objective. Utility Model Content

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0021] For example, Figures 1-4As shown, the utility model provides a kind of hot riveting device for throttle dust cover, and the hot riveting device includes bottom plate 1, dust cover limiting block 3 and side stand 2 are equipped on bottom plate 1;Side stand 2 is connected with hot riveting mechanism;The upper end of dust cover limiting block 3 is equipped with dust cover limiting groove 4;

[0023] In the embodiment, hot riveting head 10 is connected to the lower end of heating tube 9, and is located above dust cover limiting groove 4;The lower end of hot riveting head 10 is also provided with riveting head arc groove 16.

[0024] In the embodiment, the driving component one is servo motor 6, and is fixedly connected with side stand 2 through fixed plate 5.Under the driving of servo motor 6, pressing block 7, connecting plate 13, heating tube 9 and hot riveting head 10 can move up and down synchronously.

[0025] As shown, Figure 4 The lower end of hot riveting head 10 is provided with riveting head arc groove 16, i.e., arc-shaped groove;In hot riveting operation, first make plastic insertion column 15 on fixed support insert into insertion hole on PCB board 14, then plastic insertion column 15 is located directly below riveting head arc groove 16, start driving component one, hot riveting head 10 is pressed down, riveting head arc groove 16 presses the upper end of plastic insertion column 15, the upper end of plastic insertion column 15 is melted after being heated and deformed, becomes mushroom head shape.The horizontal width of the upper end of deformed plastic insertion column 15 becomes larger than the hole diameter of insertion hole, so that plastic insertion column 15 can be prevented from being separated from insertion hole on PCB board 14, and fixed connection of PCB board 14 and fixed support is realized.The number of heating tube 9 and hot riveting head 10 can be set according to the number of plastic insertion column 15 required for hot riveting.

[0026] Meanwhile, in the embodiment, displacement sensor for detecting the moving stroke of pressing block 7 and temperature sensor for detecting the temperature of heating tube 9 are additionally provided.Meanwhile, pressure sensor 8 is additionally provided at the lower end of pressing block 7.When pressure sensor 8, displacement sensor and temperature sensor are connected with control system, the control system can timely master the displacement information of pressing block 7, the pressure information received by pressure sensor 8 and the temperature information of heating tube 9 and the like in hot riveting process, and compare with preset value to analyze hot riveting operation process, so as to be beneficial to control system to control the operation of entire hot riveting device with higher quality and higher precision.For example, when the temperature is too high, stop heating heating tube 9, to avoid excessive deformation of plastic insertion column 15;For example, when pressing block 7 is pressed to the preset height, stop the pressing operation of pressing block 7, to avoid that the lower end of hot riveting head 10 moves excessively and causes damage to fixed support.

[0027] Additionally, we can choose to make the connection between the hot riveting head 10 and the heating tube 9 detachable, so that the hot riveting head 10 can be replaced at any time to accommodate plastic plugs 15 of different sizes, or to achieve efficient parts replacement operation after the hot riveting head 10 is damaged.
