Description

Technical Field

[0001] The utility model relates to the technical field of pin press-fitting, and more specifically, to an automatic pin press-fitting device. Background Art

[0002] Flange, also called flange flange or flange. Flange is a part that connects shafts to each other and is used to connect pipe ends. It is also used as a flange on the inlet and outlet of equipment to connect two devices, such as reducer flange.

[0003] In the production or installation process of flanges, it is usually necessary to insert pins to facilitate subsequent production and processing. The traditional pin press-fitting method is usually that the operator holds a hammer with one hand and places one end of the pin on one side of the through hole with the other hand, then aims at the top of the pin and swings the hammer hard to press the pin into the hole. However, due to the high tolerance requirements on the depth of the pin press and the side clearance (the gap between the pin and the groove wall), the traditional press-fitting method not only has a high scrap rate, but also takes a long time to train personnel, has low production efficiency, and is prone to safety accidents. Utility Model Content

[0004] The utility model aims to provide an automatic pin press-fitting device, which solves the problems in the prior art of high scrap rate, low production efficiency and easy occurrence of safety accidents due to manual pin press-fitting.

[0005] The above-mentioned technical purpose of the utility model is achieved through the following technical solutions: an automatic pin pressing device, comprising a workbench, a support frame is arranged on the top of which, and an electric box is arranged on one side of the support frame; a pressing assembly is arranged on the support frame, and the pressing assembly is used to press the pins on the flange; a limiting assembly is arranged on the support frame directly below the pressing assembly, and the limiting assembly is used to fix the flange; wherein the electric box supplies power to the pressing assembly; the pressing assembly comprises a hydraulic cylinder installed on the top of the support frame, the output end of the hydraulic cylinder passes downward through the support frame and is fixedly connected to a connecting plate, two guide rods are symmetrically arranged on the top of the connecting plate, the top ends of the two guide rods both penetrate upward through the top of the support frame and are slidably connected thereto, a mounting block is fixedly arranged at the bottom of the connecting plate, and a pressure head is installed at the bottom of the mounting block.

[0006] The working principle of this technical solution is as follows: when in use, the operator first manually inserts the bottom end of the pin into the through hole of the flange at least a small section, then uses the limit assembly to fix the flange, and then starts the press-fit assembly through the electrical box to press the pin down to the appropriate position, and then removes the flange and repeats the above operation.

[0007] In summary, the utility model has the following beneficial effects:

[0008] Compared with the prior art, the utility model provides an automatic pin pressing device which cooperates with each other by setting a support frame, a limit assembly, a pressing assembly and an electrical box, so that the operator only needs to manually press the pin into the through hole a small distance, and the subsequent pressing work is completed by the pressing assembly and the limit assembly, which improves the pin pressing efficiency, ensures the pressing quality, and avoids the occurrence of safety accidents.

[0009] Furthermore, the limiting assembly includes a base fixedly arranged on the inner side of the bottom of the support frame, a fixing block is fixedly connected to the base, a limiting groove is provided on the top of the fixing block, and the limiting groove is adapted to the flange.

[0010] Furthermore, a storage chamber is provided in the workbench, and a box door is provided on the front side of the workbench.

[0016] The following is combined with Figure 1 —3 The utility model is further described in detail.

[0017] like Figure 1 As shown, an embodiment of the utility model proposes an automatic pin press-fitting device, including a workbench 1, a support frame 3 is arranged on the top, and an electric box 9 is arranged on one side of the support frame 3; a press-fitting assembly is arranged on the support frame 3, and the press-fitting assembly is used to press the pin 13 on the flange 14; a limit assembly is arranged on the support frame 3 directly below the press-fitting assembly, and the limit assembly is used to fix the flange 14; wherein, the electric box 9 supplies power to the press-fitting assembly.

[0018] The specific working process is: when in use, the operator first manually inserts the bottom end of the pin 13 into the through hole 15 of the flange 14 at least a small section, and then uses the limit assembly to fix the flange 14, and then starts the press-fit assembly through the electrical box to press the pin 13 down to the appropriate position, and then removes the flange 14 and repeats the above operation.

[0019] In this embodiment, by setting the support frame 3, the limit assembly, the press-fitting assembly and the electrical box 9 to cooperate with each other, the operator only needs to manually press the pin 13 into the through hole 15 a small distance, and the subsequent press-fitting work is completed by the press-fitting assembly and the limit assembly, which improves the press-fitting efficiency of the pin 13, ensures the press-fitting quality, and avoids the occurrence of safety accidents.
