[0048] The utility model is described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the utility model, but do not limit the utility model in any form. It should be pointed out that for those of ordinary skill in the art, several changes and improvements can be made without departing from the concept of the utility model. These all belong to the protection scope of the utility model.

[0049] The utility model provides a shaft sleeve locking screw device, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, it includes a controller, a bracket 1, a first driving mechanism installed on the bracket 1, a vacuum screw rod 2 connected to the first driving mechanism, a material trough 3 located below the vacuum screw rod 2 and arranged on the bracket 1, positioning fixtures 4 respectively arranged on both sides of the material trough 3, and a vibration plate 8. The bracket 1 serves as a supporting structure of the entire device, provides a supporting carrier, and installs other components. Screws 9 are prevented from being arranged in the vibration plate 8, and the screws 9 are provided to the entire device through vibration.

[0050] like Figure 3 As shown, the positioning fixture 4 is provided with a plurality of sleeve installation positions, and the sleeve installation positions are used to position the sleeve 10. The positioning fixture 4 realizes the positioning function through the positioning cylinder 13, and the sleeve 10 is clamped or released by extending and retracting the push rod of the positioning cylinder 13. In a possible embodiment, 32 sleeve installation positions are provided on the positioning fixtures 4 on both sides, and the 32 sleeve installation positions in each positioning fixture 4 are arranged in an array on the positioning fixture 4.

[0051] like Figure 1 , Figure 2 , Figure 6 As shown, the material trough 3 is provided with a conveying cylinder 31, a sensor 33 and a screw picking position 32. The sensor 33 is arranged on the side of the screw picking position 32, and is used to detect whether there is a screw 9 on the screw picking position 32. The first driving mechanism can drive the vacuum screw rod 2 to move, and then can pick up the screw 9 located on the screw picking position 32 to the sleeve 10 on the sleeve mounting position and tighten it. The first driving mechanism, the vibration plate 8, the conveying cylinder 31, and the sensor 33 are electrically connected to the controller respectively. The controller can control the action of each power mechanism and can receive the signal transmitted by the sensor 33.

[0052] During specific operation, the vibrating plate 8 can transport the screw 9 to the waiting position inside the material trough 3 through the material delivery pipe 12, and push the screw 9 at the waiting position in the material trough 3 to the screw picking position 32 through the conveying cylinder 31. When the sensor 33 detects that there is a screw 9 on the screw picking position 32, the sensing signal is transmitted to the controller, and the controller controls the first driving mechanism to drive the vacuum screw rod 2 to move and remove the screw 9 on the screw picking position 32. At this time, the sensor 33 detects that there is no screw 9 on the screw picking position 32, and transmits the sensing signal to the controller. The controller controls the conveying cylinder 31 to retreat, so that another screw 9 falls on the waiting position. The controller controls the conveying cylinder 31 to advance and push the fallen screw 9 to the screw picking position 32. This cycle is repeated to achieve a continuous supply of screws 9. Among them, the sensor 33 preferably adopts a photoelectric sensor 33, and a slide rail matching the conveying cylinder 31 is provided on the material trough 3 to make the conveying cylinder 31 more accurate when reciprocating.

[0053] like Figure 1 , Figure 2 As shown, the first driving mechanism includes a slider 5, a horizontal motor installed on the slider 5, a vertical motor and an execution head 6 driven by the vertical motor. The vacuum screw rod 2 is installed at the lower end of the execution head 6. A horizontal slide rail 11 is provided on the bracket 1. The horizontal motor can drive the slider 5 to move left and right along the horizontal slide rail 11 and then drive the vacuum screw rod 2 to reach directly above the screw picking position 32 or directly above the sleeve installation position. Driven by the vertical motor, the vacuum screw rod 2 moves upward or downward to complete the picking and tightening action of the screw 9.

[0054] It should be noted that, since the sleeve installation positions are arranged in an array on the positioning fixture 4, in a possible embodiment, a fixture driving mechanism is provided at the bottom of the positioning fixture 4, and the fixture driving mechanism can drive the positioning fixture 4 to move in the front-to-back direction so that the sleeve installation positions of different rows are adjusted to be directly below the movement trajectory of the vacuum screw rod 2. That is to say, after the sleeves 10 on each row of sleeve installation positions have completed the screw tightening action, the fixture driving mechanism drives the positioning fixture 4 to move forward one row, so that the sleeve installation positions of the next row are located directly below the movement trajectory of the vacuum screw rod 2, and so on. The fixture driving mechanism can use a motor and a chain driving structure to realize the function of driving the positioning fixture 4 forward and backward. In addition, the sleeve 10 on the positioning fixture 4 can be placed or removed through a fixture disk that matches the positioning fixture 4, thereby improving the processing efficiency.

[0055] like Figure 1As shown, the first driving mechanism also includes a rotating motor installed inside the execution head 6 and a rotating rod 7 drivingly connected to the rotating motor. The lower end of the rotating rod 7 extends into the interior of the vacuum screw rod 2 and when the vacuum screw rod 2 picks up the screw 9 and moves to the sleeve installation position, the rotating motor drives the rotating rod 7 to rotate so that the screw 9 can be tightened and assembled onto the sleeve 10. Specifically, the vacuum screw rod 2 is a tubular structure, and the vacuum screw rod 2 is connected to a vacuum suction pipe 16, as shown in FIG. Figure 7 As shown, the end of the rotating rod 7 extends from the top of the vacuum screw rod 2 into the interior of the vacuum screw rod 2, so that a accommodating space is formed at the front end of the vacuum screw rod 2. When the vacuum suction tube 16 is evacuated, the accommodating space instantly becomes a negative pressure space, and the screw 9 is sucked into the accommodating space and tightly attached to the end of the rotating rod 7. When the vacuum screw rod 2 reaches the top of the sleeve 10, the rotating motor drives the rotating rod 7 to rotate and then screws the screw 9 onto the sleeve 10 to complete the assembly action.

[0056] In order to increase the convenience of operation, the bracket 1 is also provided with a touch screen 14 and a start-stop switch 15. The touch screen 14 and the start-stop switch 15 are electrically connected to the controller. The required settings and the start-stop switch 15 can be completed through the touch screen 14 and the start-stop switch 15. The operation is simple and convenient, and the processing efficiency is improved.

[0057] Each motor in the utility model preferably adopts a stepper motor. The utility model has a simple structure, a reasonable design, and is easy to operate, thereby reducing the difficulty of manual operation, improving production efficiency, and ensuring product quality.

[0058] It should be noted that the vibration plate 8 is equipped with a separate adjustment controller, and the discharge end of the screw vibration plate 8 is connected to the feed pipe 12. When the vibration plate 8 vibrates, the screw 9 falls along the feed pipe 12 onto the material trough 3 due to the gravity of the screw 9. Among them, the vibration plate 8 belongs to the prior art and will not be described here.

[0059] The controller can adopt a PLC control system, and the touch screen 14 is connected to the PLC control system to program and set various required parameters, so as to finally achieve normal operation of the device.
