[0005] Furthermore, a cylinder is provided on the top of the pressing device, and the mounting seat is connected to the telescopic rod of the cylinder.

[0006] Furthermore, there are two auxiliary wheels, which are arranged on the front surface of the mounting seat.

[0007] Furthermore, an arc-shaped placement opening is provided in the middle of the sliding plate.

[0008] Furthermore, a vertical rail is provided on the positioning plate; and the guide wheel is slidably connected to the vertical slide rail.

[0009] The beneficial effect of the utility model is as follows: the utility model is provided with two sleeve-connected pressure heads, and a spring is arranged in the first pressure head, so that the first pressure head first presses the center of the bottom rubber cylinder cover for the first time, and then the external second pressure head presses the outer periphery of the rubber cylinder cover for the second time. The two pressings ensure that the entire rubber cylinder cover is subjected to downward pressure, so that the buckle of the rubber cylinder cover can be smoothly and completely assembled with the rubber cylinder, improving the phenomenon of uneven force in mechanical installation in the past, causing the cylinder cover to not be pressed into place and warping, and at the same time can save labor, reduce production costs, and improve assembly efficiency.

[0015] 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.

[0016] like Figures 1 to 3The EFD rubber cartridge tail cover assembly tool shown in the figure includes a pressing device, which includes a guide wheel 11, a first pressing head 14, a second pressing head 13 and a mounting seat 12; the first pressing head 14 is connected to the bottom surface of the mounting seat 12 through a compression spring; the second pressing head 13 is sleeved on the outside of the first pressing head 14, and the two are slidably connected; the top of the second pressing head 13 is fixedly connected to the bottom surface of the mounting seat 12; when the compression spring is not compressed, the first pressing head 14 can extend from the bottom of the second pressing head 13; the guide wheel 11 is located on both sides of the mounting seat 12; the guide wheel 11 and the positioning plates on both sides 5 sliding connection; the bottom of the two side positioning plates 5 is provided with a fixed horizontal plate 3, and the bottom of the fixed horizontal plate 3 is provided with a slide rail 6; two mobile bases 10 are symmetrically arranged on both sides of the pressing device; the mobile base 10 is composed of two vertical plates 2 arranged front and back and a bottom sliding plate 4; the sliding plate 4 is slidably connected with the fixed horizontal plate 3; the side edges of the vertical plates adjacent to the two mobile bases 10 are convex bevel edges 9; the surface of the mounting seat 12 is provided with auxiliary wheels 8; the auxiliary wheels 8 are located in the middle of the two mobile bases 10; the auxiliary wheels 8 move downward, which can make the two mobile bases 10 move to both sides as a whole.

[0017] A cylinder 1 is provided on the top of the pressing device, and the mounting seat 12 is connected to the telescopic rod 15 of the cylinder 1.

[0018] There are two auxiliary wheels 8 , which are arranged on the front surface of the mounting seat 12 and are rotatably connected to the mounting seat 12 .

[0019] The middle of the sliding plate 4 is provided with an arc-shaped placement opening 16 for placing the rubber cartridge tail cover 7 .

[0020] The positioning plate 5 is provided with a vertical track; the guide wheel 11 is slidably connected with the vertical slide rail, and the guide wheel 11 and the vertical slide rail mainly play a positioning role.

[0021] When the device is used, the rubber cylinder tail cover 7 is first placed in the arc-shaped placement opening 16, and then the cylinder 1 is started to drive the mounting seat 12 to move downward. The first pressure head 14 first contacts the center position of the bottom rubber cylinder tail cover 7 and presses the tail cover for the first time. Then the mounting seat 12 continues to move downward to compress the internal compression spring, so that the first pressure head 14 and the second pressure head 13 slide relative to each other. The external second pressure head 13 continues to move downward to squeeze the edge of the rubber cylinder tail cover 7 for the second time, and the tail cover is completely installed in the rubber cylinder; during the downward movement of the mounting seat 12, the auxiliary wheel 8 moves downward along the outer convex bevel edge 9 of the mobile base 10, so that the mobile base 10 slides to both sides, and finally causes the bottom arc-shaped placement opening to separate from the tail cover.
