DETAILED DESCRIPTION

[0019] In order to more clearly illustrate the technical features of this solution, this solution is described below through specific implementation methods.

[0020] See also Figure 1 - Figure 2, a press-fitting tool for the eccentric connecting pipe of a water pump 10, comprising a bottom plate 1, a water pump fixing plate 5 vertically slidably arranged on the bottom plate 1, a water pump 10 detachably arranged on the water pump fixing plate 5, a supporting boss 6 vertically arranged on the bottom plate 1, a connecting pipe 61 sleeved outside the supporting boss 6, a through hole allowing the connecting pipe 61 to pass through arranged on the water pump fixing plate 5, the interface of the water pump 10 facing the through hole, and the connecting pipe 61 passing through the through hole and connecting with the interface of the water pump 10.

[0021] A plurality of guide posts 2 are arranged in an array on the bottom plate 1, guide sleeves 4 are arranged at corresponding positions on the water pump fixing plate 5, the guide posts 2 are vertically slidably arranged in the guide sleeves 4, a return spring 3 is sleeved outside the guide sleeve 4, one end of the return spring 3 is connected with the bottom plate 1, and the other end of the return spring 3 is connected with the water pump fixing plate 5.

[0022] A plurality of sliding holes 51 are arranged on the water pump fixing plate 5, screws 9 are slidably arranged in the sliding holes 51, and the threaded parts of the screws 9 are connected with the bottom plate 1.

[0023] A locking nut two 91 for fastening the bottom plate 1 is sleeved on the threaded part of the screw 9, so that the screw is fixed more firmly on the fixing plate 1 through the locking nut two 91.

[0024] A plurality of positioning pin shafts 7 corresponding to the mounting holes of the water pump 10 are arranged on the water pump fixing plate 5, and the positioning pin shafts 7 are detachably inserted into the mounting holes of the water pump 10.

[0025] A screw rod 8 is arranged through the water pump 10, one end of the screw rod 8 is connected with the water pump fixing plate 5, a limiting plate 82 for pressing the water pump 10 is arranged outside the screw rod 8, and a bearing head 83 is arranged at the other end of the screw rod 8.

[0026] A locking nut one 81 for fastening the water pump fixing plate 5 is arranged outside the screw rod 8.

[0027] The specific working process of the utility model:

[0028] Fix the bottom plate 1 on a stable workbench surface, pass the connecting pipe 61 through the water pump fixing plate 5 from top to bottom and sleeve it on the supporting boss 6 to complete the placement of the connecting pipe 61;

[0029] Position the water pump 10 by sleeving it on the positioning pin shaft 7 and the screw rod 8 respectively. After the limiting plate 82 is sleeved on the screw rod 8, tighten the bearing head 83 to complete the installation of the water pump 10 and the water pump fixing plate 5;

[0030] Use a press to press down the pressure head 83. The pressure head 83 presses the water pump 10 together with the water pump fixing plate 5 downward through the limit plate 82. At this time, the guide sleeve 4 slides along the guide post 2 against the elastic force of the return spring 3. Through the cooperation of the guide sleeve 4 and the guide post 2, it is ensured that the water pump fixing plate 5 drives the water pump 10 to slide downward. The water pump fixing plate 5 continues to slide downward until the connecting pipe 61 penetrates into the water outlet of the water pump 10;

[0031] Subsequently, the press rises. The water pump fixing plate 5 rises under the action of the elastic force of the return spring 3 and stops when the head of the screw 9 contacts the sliding hole 51 of the water pump fixing plate 5, preventing the water pump fixing plate 5 from coming off. Finally, loosen the pressure head 83 to remove the water pump 10, and the press-fitting operation of the water pump 10 and the connecting pipe 61 is completed.

[0032] The water pump fixing plate 5 is limited by the cooperation of multiple guide posts 2 and guide sleeves 4, making the force more stable when the water pump fixing plate 5 slides along the bottom plate 1. The connecting pipe 61 is limited by sleeving it on the support boss 6, making the press-fitting of the connecting pipe 61 more stable and accurate, and the connection of the water pump 10 to the connecting pipe 61 is firm and reliable;

[0033] The return spring 3 bounces up the water pump fixing plate 5, and the cooperation of the screw 9 and the sliding hole 51 limits the water pump fixing plate 5 to prevent it from coming off, so as to perform the press-fitting of the next connecting pipe 61. The reset of the tooling is convenient, fast, efficient and stable, improving the efficiency of the press-fitting of the water pump 10 connecting pipe;

[0034] Lock the screw rod 8 to the connecting plate of the water pump 10 through the first lock nut 81. A limit plate 82 is sleeved on the outside of the screw rod 8 to fix and limit the water pump 10, making the connection between the water pump 10 and the connecting pipe 61 of the water pump 10 more firm and reliable, and the press-fitting of the water pump 10 connecting pipe more firm.

[0035] The technical features not described in this utility model can be realized by or adopted from the prior art and will not be elaborated here. Of course, the above description is not a limitation of this utility model, and this utility model is not limited to the above examples. Changes, modifications, additions or substitutions made by those of ordinary skill in the art within the essence of this utility model should also fall within the protection scope of this utility model.
