Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1

[0029] Reference Figure 1-4As shown, this utility model discloses a device for assembling brushes for dual-type machines, comprising a workbench 1. The workbench 1 is equipped with a first jig 2, a second jig 3, and a vertical plate 4. The first jig 2 and the second jig 3 are located on opposite sides of the vertical plate 4, facilitating operation by maintenance workers who can use two different sets of jigs without interference. The overall space occupied by the device is relatively small. The vertical plate 4 is equipped with a first manual air valve 16, a second manual air valve 17, and a mounting plate 14. A first cylinder 15 and a second cylinder 13 are fixed to the mounting plate 14. The first cylinder 15 is connected to the first manual air valve 16 via a first air pipe and drives the second manual air valve 17. A first pressure head 7 moves up and down, suspended above the first fixture 2. The first fixture 2 is clamped with a first brush holder 20. A first brush 21 is placed on the first brush holder 20 and assembled by pressing down with the first pressure head 7. The first brush 21 is assembled onto the first brush holder 20. The second cylinder 13 is connected to the second manual air valve 17 through the second air pipe and drives the second pressure head 8 to move up and down. The second pressure head 8 is suspended above the second fixture 3. A second brush holder 22 is clamped on the second fixture 3. A second brush 23 is placed on the second brush holder 22 and assembled by pressing down with the second pressure head 8.

[0030] This utility model device is a production auxiliary equipment. Its specific function is to perform some repair work on defective products (such as missing or improperly inserted brushes) generated during the brush assembly process of other automated equipment. Since its actual usage rate is low, it is designed as a semi-automated device for easy, labor-saving operation and cost-effectiveness. When a specific brush holder for a particular machine type is needed, the corresponding fixture is positioned so that it faces the operator. When working with the first brush holder 20, the left hand places the product to be repaired into the first fixture 2, the left hand is retracted, and then the right hand activates the lever switch of the first manual air valve 16 (since the manual air valve is always on the left side of the vertical plate 4 when facing the operator). The product to be repaired is placed on the left side of the machine, and the repaired product is placed on the right side. The left hand puts the material in, and the right hand operates the toggle switch. The operator should turn their body to remind the left hand to be pulled back in time to avoid safety accidents. Finally, the right hand picks up the material. The entire operation combines the operation of the left and right hands with the material position and the safe use of the machine, resulting in high work efficiency. After the first pressure head 7 is pressed down to the position, the lever switch of the first manual air valve 16 is turned back, and the first pressure head 7 is reset. The right hand takes out the processed product from the first jig 2 and puts it away. A complete set of repair actions is completed. Repeat the above operation to carry out the repair operation of the next product. The repair operation steps of the product on the second jig 3 are the same, and will not be described in detail.

The second pressure head 8 is mounted on the second fixed base 10, which is connected to the second cylinder 13. Simultaneously, as described above, the first fixed base 9 is also mounted on the first slider 11, which is slidably disposed on the first slide rail 6, which is fixed to the vertical plate 4. The second fixed base 10 is also mounted on the second slider 12, which is slidably disposed on the second slide rail 5, which is fixed to the vertical plate 4.

[0033] Furthermore, the first fixed seat 9 is connected to the telescopic shaft of the first cylinder 15, and the second fixed seat 10 is connected to the telescopic shaft of the second cylinder 13. In addition, the first cylinder 15 and the second cylinder 13 are arranged opposite to each other, with the cylinder body of the first cylinder 15 located directly above the first fixture 2, and the cylinder body of the second cylinder 13 located directly above the second fixture 3. The first slide rail 6 and the second slide rail 5 are respectively vertically fixed on both sides of the upright plate 4, and the slide rails slide in cooperation with the corresponding sliders, ensuring that the fixed seat connected to the slider can reciprocate vertically under the drive of the corresponding cylinder.

[0034] Furthermore, the first manual air valve 16 and the second manual air valve 17 are respectively installed on the side of the upright plate 4. The first manual air valve 16 is located on the left side of the first slide rail 6, and the second manual air valve 17 is located on the left side of the second slide rail 5. The purpose of installing the manual air valves on the left side facing the operator is to make the entire operation process coordinated and ensure safety during the operation process, so as to avoid the fingers being crushed by the pressure head.
