Description

Technical Field

[0001] This utility model relates to a screw-locking device, and more particularly to a quick screw-locking device, belonging to the field of machining auxiliary equipment. Background Technology

[0002] In the traditional screw-locking process of machining, the traditional operation is as follows: the operator places the product on the workbench, manually pre-locks the screws, then holds the product with one hand and uses an electric screwdriver in the other hand to tighten the screws. This traditional manual operation method is prone to quality problems and also leads to low screw-locking efficiency.

[0003] Therefore, how to achieve rapid automation of screw fastening has become a technical issue that this industry hopes to solve in actual production. Utility Model Content

[0004] The main technical problem solved by this invention is to design a fast screw-locking device. The operator places the screw in reverse in the travel cavity of the electric screw head, and the screw is locked into the screwdriver head by gravity. The rotation of the electric screwdriver drives the screw to rotate. Then, the product is placed in a fixed position, which allows the screw to be smoothly locked into the screw hole, completing the screw-locking action. Finally, the product is removed and a new product is put in. This method can improve product quality and greatly improve screw-locking efficiency.

[0005] This quick screw-locking device is characterized by: a box-type base 22 and a product placement platform 3 and a support plate 16 disposed on the upper part of the box-type base; and a pneumatic lifting mechanism and an electrically driven screw-locking mechanism disposed between the support cover plate 16 on the upper part of the box-type base 22 and the product placement platform 3; the pneumatic lifting mechanism consists of a pull rod cylinder 10 disposed on the side of the box-type base 22, a pneumatic solenoid valve 17 disposed on the support cover plate 16, and a set of left guide rods 9 and right guide rods 13 symmetrically distributed between the product placement platform 3 and the support plate 16; the electrically driven screw-locking mechanism consists of electrically driven screwdrivers disposed on the upper and lower surfaces of the support cover plate 16.

[0006] Furthermore, the pneumatic solenoid valve 17 forms an air supply channel with the pull rod cylinder 10 through the air guide pipe 10.1, and is connected to the bottom of the product placement platform 3 through the extension rod 10.2 of the pull rod cylinder.

[0007] Furthermore, both the left guide rod 9 and the right guide rod 13 are provided with a guide sleeve fixed on the support cover plate 16, and the upper ends of the left and right guide rods are connected to the bottom of the product placement platform 3.

[0008] Furthermore, the electric drive screwdriver consists of a left screwdriver 4 and a right screwdriver 7 symmetrically distributed on the surface of the support cover plate 16. The upper part of the left and right electric drive screwdrivers is aligned with a screw positioning hole 3.1 provided on the product placement platform 3, and the lower part is connected to the corresponding electric motor output shaft provided in the box base 22.

[0009] Furthermore, a vertically downward sensing rod 6 is provided on the lower surface of the product placement platform 3.

[0010] Furthermore, the support cover plate 16 is also equipped with a sensor 15 and an up / down switch 12.

[0011] Furthermore, the box-type base 22 is equipped with a power supply box 20 and a 220V power supply 18, and a speed controller 19 and a main switch 21 are provided on the base box body.

[0012] The quick screw-locking device proposed based on the above technical solution has the following advantages:

[0013] 1. It can improve production efficiency. Compared with the original production process of manually tightening screws, which can only tighten one screw at a time and takes 8 seconds to tighten each screw, the current fast automatic screw tightening can tighten two screws at the same time, with a total time of 4 seconds.

[0014] 2. By using automatic screw fastening, operator fatigue and skill requirements are reduced;

[0015] 3. Reduce product scratches and screw misalignment caused by manual operation;

[0016] 4. The automatic screw fastening design can be extended to the screw fastening process of similar products, further improving the level of factory automation. Attached Figure Description
