Problems solved by technology

The resulting dimensional deviation will be transmitted to the installed accessories such as the door hinge, resulting in insufficient installation accuracy of the accessories, large fluctuations in fit, difficulty in online adjustment, and sometimes off-line repairs are required
In addition, when the positioning pin is mated with the positioning hole, it is directly inserted and pulled out. After repeated use, the positioning pin will be worn out, which will affect the accuracy of its cooperation with the positioning hole, and the installation accuracy of the door hinge and other accessories will require secondary adjustments after assembly. , affecting production efficiency
The fixture is usually removed during the second adjustment, and it is difficult to adjust the position of the door and the bolt with one hand.

Embodiment Construction

[0019] Embodiments of the present invention are described in detail below.

[0020] Such as figure 1 As shown, the tension positioning round pin 10 of the present invention has at least two pin petals 12 separated from each other. Tensioning positioning round pin 10 is also called tensioning pin, or positioning pin. Closing the pin petals 12 of the tension pin can make the tension pin 10 shrink smaller, and the outer dimension of the tension pin 10 is smaller than the diameter of the positioning hole, so that it can be easily inserted into the positioning hole, and then opened by the driving device. The pin petal 12 of the tight pin makes the tension pin fit closely with the positioning hole. At this time, the peripheral dimension of the positioning pin 10 is equal to the diameter of the positioning hole, ensuring that there is no gap between the tensioning pin 10 and the positioning hole, improving the positioning accuracy, and ensuring the clamp. Positioning accuracy and s...

Abstract

The invention discloses a tensioning and positioning round pin, which is provided with at least two pin flaps separated from each other, wherein when the pin flaps of the tensioning pin are folded, the tensioning pin contracts, so that the tensioning pin can easily extend into a positioning hole; and then, the tensioning pin is tightly combined with the positioning hole by unfolding the pin flapsof the tensioning pin, so that no gap exists between the tensioning pin and the positioning pin, the positioning accuracy and stability of a clamp are ensured, the installation accuracy of fittings such as a vehicle door hinge and the like is ensured, one-time installation success rate of a vehicle door is increased, the production efficiency is improved and the fluctuation of product quality is reduced. The invention also discloses a round pin-inserted positioning device. The round pin-inserted positioning device comprises the tensioning and positioning round pin provided with at least two pin flaps which are separated from each other, and an expansion device which is fixedly connected with the root parts of the pin flaps and drive the pin flaps to move along the radial direction. By adopting the round pin-inserted positioning device, the installation accuracy of the vehicle door hinge can be enhanced and the one-time installation success rate of the vehicle door can be increased.

Description

technical field [0001] The invention relates to a tension positioning round pin. The invention also relates to a pin positioning device, in particular to a round pin insertion type positioning device. Background technique [0002] In manufacturing, especially in automobile manufacturing, positioning pins are usually used to insert into the positioning holes of the car body for positioning when installing accessories such as car doors. When the diameter is 25mm, the diameter of the positioning pin is 24.7mm. The resulting dimensional deviation will be transmitted to the installed accessories such as door hinges, resulting in insufficient installation accuracy of the accessories, large fluctuations in fit, difficulty in online adjustment, and sometimes off-line repairs are required. In addition, when the positioning pin is mated with the positioning hole, it is directly inserted and pulled out. After repeated use, the positioning pin will be worn out, which will affect the a...
