DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0037] Reference Figure 1 and Figure 2 The utility model provides an embodiment: a positioning tool for processing a steering gear housing, comprising a workbench 1, a vertical shell 3 is fixedly connected to the rear end of the left side of the top wall of the workbench 1, a servo motor 4 is fixedly connected to the right side of the inner top wall of the vertical shell 3, a first gear 5 is fixedly connected to the output end of the servo motor 4, a limiting shell 6 is fixedly connected to the front top of the vertical shell 3, a swivel 7 is rotatably connected to the inner bottom wall of the limiting shell 6, a second gear 8 is fixedly connected to the top wall of the swivel 7, the second gear 8 is meshed with the first gear 5, a threaded column 9 is meshed with the inner wall of the second gear 8, and a pressing hollow column 10 is rotatably connected to the bottom end of the threaded column 9, the workbench A fixed column seat 11 is fixedly connected to the middle of the left side of the top wall of the workbench 1, the top of the fixed column seat 11 is engaged with the inner wall of the hollow column 10, the upper and lower ends of the fixed column seat 11 are sleeved with rubber plugs 12, and the middle of the fixed column seat 11 is penetrated with a shell part 13, a placement component is arranged in the middle of the top wall of the workbench 1, and a collecting mechanism 2 is arranged on the bottom wall of the workbench 1; the placement component includes a support seat 16, the bottom wall of the support seat 16 is fixedly connected to the middle of the top wall of the workbench 1, an electric telescopic rod 17 is fixedly connected to the front side of the inner wall of the support seat 16, and a support block 18 is fixedly connected to the output end of the electric telescopic rod 17 and the rear side of the inner wall of the support seat 16;

[0038] Specifically, the rubber plug 12 below is tightly sleeved on the outer wall of the fixed column seat 11 to ensure its stability. Next, the shell part 13 is accurately sleeved on the middle part of the fixed column seat 11 to keep it in a stable position. The middle part of the shell part 13 should be placed on the top of the two support blocks 18, which is to provide stable support in subsequent operations. Then, by starting the electric telescopic rod 17, the front support block 18 can fix the bottom of the shell part 13 to enhance its stability. On this basis, the upper rubber plug 12 is sleeved on the top of the fixed column seat 11 to form two upper and lower clamped rubber plugs 12, and the servo motor 4 is started, which is the key to driving the operation of the entire device. Through the operation of the servo motor 4, the first gear 5 can drive the second gear 8 to rotate. It is worth noting that the displacement limit of the swivel 7 prevents the second gear 8 from being displaced, ensuring the stability of the equipment. During the rotation of the second gear 8, the threaded column 9 threadedly connected to the inner wall of the second gear 8 will also rotate and displace accordingly. This rotational displacement will drive the pressing hollow column 10 to move downward, so that it is engaged with the top of the fixed column seat 11. In this way, the positioning and clamping of the housing part 13 is completed. Finally, by pressing the two rubber plugs 12, they are installed in the two symmetrical holes of the housing part 13. The completion of this step not only reduces the difficulty of operation, but also effectively improves the work efficiency.

[0039] Reference Figure 1 and Figure 3 The collecting mechanism 2 includes an extraction fan 201, the top wall of the extraction fan 201 is fixedly connected to the left side of the bottom wall of the workbench 1, the extraction end of the extraction fan 201 is connected to a connecting pipe 202, the right end of the connecting pipe 202 is connected to a collecting box 203, a filter plate 204 is fixedly installed on the inner wall of the collecting box 203, the front side of the collecting box 203 is connected to an extraction pipe 205, the top end of the extraction pipe 205 is connected to an extraction head 206, the bottom wall of the extraction head 206 is fixedly connected to the rear side of the middle part of the top wall of the workbench 1; the outer wall of the extraction pipe 205 is fixedly connected to a rubber ring 207, and the outer wall of the rubber ring 207 is fixedly connected to the rear side of the extraction head 206;

[0040] Specifically, the extraction fan 201 is started. The function of the extraction fan 201 is to suck in the debris in the air and transmit the debris to the extraction head 206 through the extraction pipe 205. In this process, the operating speed and power of the extraction fan 201 are crucial, and they directly affect the extraction efficiency of the debris. Secondly, the design of the extraction head 206 is also very important. It has a certain inclination angle to ensure that as much debris as possible is sucked in. All debris will be sucked into the collection box 203. In order to avoid damage to the impeller inside the extraction fan 201, the filter plate 204 can effectively block the debris and prevent them from entering the interior of the extraction fan 201. In this way, not only can the impeller be protected from damage, but also the service life of the extraction fan 201 can be extended. In this way, not only can the pollution of the debris to the processing workshop be effectively reduced, but also the health of the operator can be protected. The rubber ring 207 makes it easy to protect the outer wall of the extraction pipe 205, thereby reducing the wear of the outer wall of the extraction pipe 205.

[0042] Specifically, the control switch 19 is electrically connected to the servo motor 4, the extraction fan 201 and the electric telescopic rod 17 respectively, so that the control switch 19 can complete the opening and closing of the device, and the protective shell 20 can protect the control switch 19 and prevent accidental touch.

[0043] Reference Figure 1 and Figure 2 A connecting block 14 is fixedly connected to the rear side of the hollow column 10, a slide groove 15 is provided in the middle of the vertical shell 3, and the connecting block 14 is slidably connected to the slide groove 15; support frames 21 are fixedly connected to the left and right sides of the bottom wall of the workbench 1, and corner pads 22 are fixedly installed on the front and rear sides of the bottom of the two support frames 21;

[0044] Specifically, the connecting block 14 is slidably connected to the slide groove 15 , so that the hollow column 10 is more stable when being pressed to be lifted and lowered, and the stability of the device is improved by the support frame 21 and the corner pad 22 .

By starting the extraction fan 201, the extraction head 206 and the extraction tube 205 can extract the debris generated by the processing, so that the debris is uniformly extracted into the inside of the collection box 203, thereby reducing the situation where the debris pollutes the processing workshop. In order to avoid damage to the impeller inside the extraction fan 201, the filter plate 204 can block the debris, thereby ensuring the service life of the extraction fan 201 and ultimately ensuring the health of the operator.
