[0007] As a preferred embodiment of the above technical solution, a mounting block is provided on the top of the bolt feeding block, and the mounting block is connected to an external lifting mechanism.

[0008] As a preferred embodiment of the above technical solution, a nut conveying plate is further included, one end of which is located in the groove of the placement seat.

[0009] The beneficial effects of the utility model are:

[0010] 1. The bolts and nuts to be installed are automatically placed from the top and bottom respectively. The nuts are moved to the corresponding positions by the rotation of the bolts to complete the installation of the bolts and nuts. The bolts and nuts can be installed automatically, thereby improving the installation speed and efficiency of plastic parts.

[0011] 2. The support pieces provided can support the incoming bolts so that they can automatically adjust under the action of gravity, and the two support pieces can be squeezed and moved in opposite directions when the bolts are installed, avoiding blocking the moving path of the bolts and affecting the installation of the bolts.

[0016] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments and the accompanying drawings.

[0017] Example

[0018] Figure 1-Figure 3 In the figure, an automatic tightening device for a bolt pair of a gas meter plastic part includes: a placement seat 10, an operating tool 20 and a bolt feeding block 30. In the present technical solution, the operating tool 20 is a screwdriver head, and the bolt matches the corresponding screwdriver head. A groove for placing the plastic part of the gas meter is provided on the surface of the placement seat 10. A tool inlet 31 and a bolt outlet 32 ​​are provided on the top and bottom of the bolt feeding block 30, respectively. A bolt inlet 33 is provided at an angle on one side of the bolt feeding block 30. A connecting hose 40 is sleeved on the surface of the bolt inlet 33. One end of the connecting hose 40 is connected to an external feeding mechanism. A receiving assembly 50 is provided in the bolt feeding block.

[0019] The nut conveying plate 70 is further included, one end of which is located in the groove of the placement seat 10 .

[0020] The bolts and nuts that need to be installed are automatically placed from the top and bottom respectively, and the nuts are moved up to the corresponding positions by rotating the bolts to complete the installation of the bolts and nuts. The bolts and nuts can be installed automatically, thereby improving the installation speed and efficiency of plastic parts.

[0021] Figure 2-Figure 3In the figure, the receiving assembly 50 includes two supporting plates 51, and a limiting rod 52 is movably inserted on one side of the supporting plate 51. A return spring 53 is sleeved on the surface of the limiting rod 52, and the two ends of the return spring 53 are respectively fixedly connected to the supporting plate 51 and the inner wall of the bolt feeding block.

[0022] The provided support pieces 51 can support the incoming bolts so that they can automatically adjust under the action of gravity, and the two support pieces 51 can be squeezed and moved in opposite directions when the bolts are installed, so as to avoid blocking the moving path of the bolts and affecting the installation of the bolts.

[0023] Figure 1-Figure 2 In the embodiment, a mounting block 60 is provided on the top of the bolt feeding block 30, and the mounting block 60 is connected to an external lifting mechanism.

[0024] Working principle: When it is necessary to install bolts and nuts on plastic parts, the nut conveying plate 70 conveys the nuts to the groove of the placement seat 10, and then the plastic part is placed inside the groove of the placement seat 10. The external feeding mechanism blows the bolts into the bolt feeding block 30 through the connecting pipe, and the bolts entering from the bolt inlet 33 fall on the two support plates 51. The two sides of the bolts slide to the bottom along the surface of the support plates 51, and the bottom ends extend from the bolt outlets 32. Then the external lifting mechanism drives the bolt feeding block 30 downward through the mounting block 60 so that the bolts are inserted into the plastic part, and the operating tool 20 moves downward from the tool inlet 31 into the bolt feeding block 30 and contacts the end of the bolt. The operating tool 20 drives the bolt to rotate so that the bolt and nut are fixed on the plastic part. After the installed plastic part is removed, the installation process can continue.

[0025] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
