[0026] The embodiments of the present utility model will be further described below with reference to the accompanying drawings.

[0027] Embodiment:

[0028] As Figure 1 、 Figure 2 and Figure 4As shown in the figure, a pneumatic pressing device for electric fusion fitting terminal is used to install and press the terminal on the electric fusion fitting 70. The device includes a frame, a pressing mechanism, a limiting mechanism and a supporting mechanism. The frame includes a base plate 11 and a mounting plate 12 vertically arranged on one side of the base plate 11. The base plate 11 is used to install the whole device on the workbench. The mounting plate 12 is respectively provided with a first adjusting hole and a second adjusting hole; The supporting mechanism includes a supporting plate 20 and a first adjusting structure. The supporting plate 20 is arranged at the bottom of the mounting plate 12 on the side far from the base plate 11. The first adjusting structure includes a first lead screw 51, a first push plate 52, a first supporting seat 53 and a connecting rod 54. The first supporting seat 53 is fixedly connected to the base plate 11 and is provided with a screw hole matching the first lead screw 51 in the middle. The first push plate 52 is slidably arranged on the base plate 11 between the first supporting seat 53 and the mounting plate 12. After passing through the screw hole, the first lead screw 51 is rotationally connected to the first push plate 52. The diameter of the connecting rod 54 matches the first adjusting hole, and the connecting rod 54 passes through the first adjusting hole and is connected to the supporting plate 20; A support 21 for the electric fusion fitting 70 is horizontally arranged on the support plate 20; The pressing mechanism includes a cylinder 31 and a pressing head 32 arranged at the end of the cylinder 31. The cylinder 31 is vertically arranged at the top of the mounting plate 12; The limiting mechanism includes a limiting block 40 and a second adjusting structure. The limiting block 40 is arranged between the cylinder 31 and the supporting plate 20 and is provided with a limiting groove penetrating up and down in the middle. The second adjusting structure includes a second lead screw 61, a second push plate 62 and a second supporting seat 63. The second supporting seat 63 is fixedly connected to the mounting plate 12 and is provided with a screw hole matching the second lead screw 61 in the middle. The second adjusting hole is a vertically arranged strip hole. The width of the second push plate 62 matches the second adjusting hole and passes through the second adjusting hole to be connected to the limiting block 40.

[0029] The above-mentioned electric fusion fitting 70 to be processed mainly includes a pipe body and two electrodes 71 arranged at both ends on the same side of the pipe body. The electrodes 71 can be preliminarily connected to the terminal before pressing.

[0030] The working principle of the above technical solution is as follows:

[0031] During processing, the electric fusion fitting 70 is sleeved outside the support 21, so that one end of the electric fusion fitting 70 abuts against the support plate 20. According to the specification of the electric fusion fitting 70, rotate the first lead screw 51 to adjust the position of the support plate 20, so that the electrode 71 of the electric fusion fitting 70 is aligned with the pressing head 32, and rotate the second lead screw 61 to adjust the position of the limiting block 40, so that the electrode 71 is between the limiting grooves. The terminal is preliminarily installed at the electrode 71, also between the limiting grooves, to prevent the electrode 71 and the terminal from shaking left and right during pressing. After the preliminary installation, the cylinder 31 can be started to drive the pressing head 32 to press down the terminal, so that the terminal is stably installed on the electric fusion fitting 70. After one end of the terminal is installed, the electric fusion fitting 70 can be removed and turned around to repeat the pressing operation. For subsequent electric fusion fittings 70 of the same specification, there is no need to adjust the first adjusting structure and the second adjusting structure, and the pressing operation can be continuously carried out.

[0032] In another embodiment, as Figure 3 shown, the support member 21 includes a mounting block 22 and a fixing block 23. The fixing block 23 can be welded to the support plate 20. The top side of the fixing block 23 is a plane. The mounting block 22 is generally cylindrical, and a mounting groove 24 matching the fixing block 23 is provided on the bottom side. A countersunk hole 25 is provided on the mounting block 22, and a connection hole 26 is provided at the corresponding position on the plane of the fixing block 23. The two can be detachably connected by a countersunk bolt. The mounting block 22 can be replaced relative to the fixing block 23 to match different specifications of the electrofusion fitting 70. The mounting block 22 can abut against the inner wall of the electrofusion fitting 70, which is beneficial to processing and further avoids the shaking of the electrofusion fitting 70 during pressing.

[0033] In another embodiment, as Figure 1-2 shown, an inclined reinforcing rod 13 is provided between the base plate 11 and the mounting plate 12. The reinforcing rod 13 increases the structural stability of the frame.

[0034] In another embodiment, a flat corner transition is provided at the edge of the limiting groove. The flat corner transition at the edge of the limiting groove is beneficial for the terminal and the electrode 71 of the electrofusion fitting 70 to enter.

[0035] In another embodiment, as Figure 2 shown, a first turning handle 55 is provided at the end of the first lead screw 51, and a second turning handle 64 is provided at the end of the second lead screw 61. This facilitates turning the first lead screw 51 and the second lead screw 61 respectively.

[0036] The above-described embodiments only represent the specific implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention.
