DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described below in conjunction with the drawings in the embodiments of the present invention. The described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] For specific embodiment 1, please refer to Figure 1-4 The utility model is a kind of auxiliary positioning tool for welding water pipes for printing machines, including a base 1, a driving screw 8 is rotatably connected to the top of the base 1, a lifting plate 6 is threadedly sleeved on the outer wall of the driving screw 8, two first support rods 7 are symmetrically fixedly connected to the top of the lifting plate 6, and the tops of the two first support rods 7 are fixedly connected to the same placement tube 10, the top of the base 1 is symmetrically fixedly connected to two limit rods 15, and the two limit rods 15 penetrate the lifting plate 6 and extend to the top of the lifting plate 6, the tops of the two limit rods 15 are fixedly connected to a top plate 14, the tops of the two top plates 14 are fixedly connected to telescopic rods 12, and the telescopic ends of the two telescopic rods 12 are fixedly connected to the same clamping tube 9, the outer walls of the two telescopic rods 12 are sleeved with tension springs 13, the bottom ends of the tension springs 13 are fixedly connected to the top of the top plate 14, the top ends of the tension springs 13 are fixedly connected to the bottom of the placement tube 10, and the two sides of the clamping tube 9 are fixedly connected to rectangular plates 11, and the bottom of the rectangular plate 11 is fixedly connected to the telescopic end of the telescopic rod 12.

[0024] Specifically: holding the clamping tube 9 by hand and lifting it can make the clamping tube 9 break away from the fit with the placing tube 10. The placing tube 10 will stretch the telescopic rod 12 and the tension spring 13 while being driven to rise. At this time, the upper pipeline and another section of the pipeline opposite to the pipeline can be placed at any position between the clamping tube 9 and the placing tube 10. When the opposite ends of the two pipelines are in contact, the clamping tube 9 is released, and the rectangular plate 11 will be pulled down due to the tension of the tension spring 13 and the telescopic rod 12 will retract.

[0025] For specific embodiment 2, please refer to Figure 1-4On the basis of the specific embodiment 1, two mounting blocks 3 are symmetrically fixedly connected to the top of the base 1, and cooling fans 4 are arranged on the tops of the two mounting blocks 3. A material receiving box 2 is clamped on the top of the base 1, and the material receiving box 2 is located directly below the lifting plate 6. The material receiving box 2 is U-shaped, and the limit rods 15 are located on both sides of the two first support rods 7. A rotating handle 5 is fixedly sleeved on the outer wall of the driving screw 8. The material receiving box 2 semi-encloses the driving screw 8 and the two limit rods 15. The bottom of the clamping tube 9 fits the top of the placement tube 10, and the height of the limit rod 15 is lower than the height of the first support rod 7.

[0026] Specifically: Since the two cooling fans 4 are installed obliquely, the wind direction of the two cooling fans 4 will blow toward the bottom of the placement tube 10 to accelerate the cooling speed of the welding point. When the handle 5 is rotated, the driving screw 8 can be driven to rotate. The rotation of the driving screw 8 will drive the lifting plate 6 and the two first support rods 7 to rise. After the two first support rods 7 are raised, they will drive the placement tube 10 to rise and lift the clamping tube 9. When the clamping tube 9 rises, it will be stretched by the rectangular plate 11 to rise and adjust the height at the same time as the placement tube 10.

[0027] The working principle of the utility model is as follows: holding the clamping tube 9 by hand and lifting it can make the clamping tube 9 break away from the fit with the placing tube 10, and the placing tube 10 will stretch the telescopic rod 12 and the tension spring 13 while being driven to rise, and at this time, the upper pipeline and another section of the pipeline opposite to the pipeline can be placed at any section between the clamping tube 9 and the placing tube 10, and when the opposite ends of the two pipelines are in contact, the clamping tube 9 is released, and the rectangular plate 11 will be pulled down due to the tension of the tension spring 13 and the telescopic rod 12 will retract, and the clamping tube 9 will be reattached to the top of the placing tube 10 to clamp and fix the pipelines at both ends, and then the welding work of the pipelines at both ends can be carried out, and if some welding positions cannot be welded, the pipeline can be slightly rotated to adjust the angle and then welded again. Then, the material receiving box 2 located on the top of the base 1 can be used to receive the fallen solder for collection. When the two cooling fans 4 are started, since the two cooling fans 4 are installed obliquely, the wind direction of the two cooling fans 4 will blow toward the bottom of the placement tube 10 to accelerate the cooling speed of the welding point. When the handle 5 is rotated, the driving screw 8 can be driven to rotate. The rotation of the driving screw 8 will drive the lifting plate 6 and the two first support rods 7 to rise. After the two first support rods 7 are raised, they will drive the placement tube 10 to rise and lift the clamping tube 9. When the clamping tube 9 rises, it will be stretched by the rectangular plate 11 to rise and adjust the height at the same time as the placement tube 10, and the two limit rods 15 can prevent the driving screw 8 from driving the lifting plate 6 to rotate together when the lifting plate 6 rises.

[0028] The standard parts used in the present invention can all be purchased from the market and can be customized according to the description in the specification and drawings. The specific connection methods of each part adopt conventional means such as mature bolts, rivets, welding, etc. in the prior art. The machinery, parts and equipment all adopt conventional models in the prior art. The control method is automatically controlled by a control unit. The control circuit of the control unit can be realized by simple programming by technicians in this field, which belongs to the common knowledge in this field. Therefore, the control method and circuit connection are no longer explained in detail in the present invention.

The preferred embodiments do not describe all the details in detail, nor do they limit the utility model to the specific implementation methods described. This specification selects and specifically describes these embodiments in order to better explain the principles and practical applications of the utility model, so that technicians in the relevant technical field can well understand and use the utility model.
