[0025] In order to facilitate the understanding of the present invention, the present invention will be described in more comprehensive and detailed manner below in conjunction with the accompanying drawings and preferred embodiments of the specification, but the protection scope of the present invention is not limited to the following specific embodiments.

[0026] like Figure 2-6As shown, the utility model discloses a guide pressing device, which is characterized in that it includes a frame 1 and a reciprocating platform 2 installed on the frame 1, a positioning tool 3 and a pressing tool 4. The bottom of the frame 1 is provided with a universal wheel that can be locked and fixed. The pressing tool 4 includes a pressing head 41 and a pressing telescopic part 42 that drives the pressing head 41 to press the rod guide rail 40. The pressing head 41 is a circular sleeve structure and can be plugged into and matched with the second matching rod 33 of the positioning sleeve rod 31. The positioning tool 3 includes a positioning sleeve rod 31 for sleeve sleeve 10, bushing 20, sealing ring 30 and rod guide rail 40. The reciprocating platform 2 drives the positioning sleeve rod 31 to reciprocate between the bottom of the pressing head 41 and the loading position 11 of the frame 1, thereby separating the two pressing positions of loading and preventing parts from detaching and injuring operators during the pressing process. In the present invention, after the positioning sleeve rod 31 of the positioning tool 3 is sequentially sleeved with the sleeve 10, bushing 20, sealing ring 30 and rod guide rail 40 from bottom to top at the loading position 11 of the frame 1, the positioning sleeve rod 31 is driven to the bottom of the pressure head 41 by the reciprocating platform 2, and then the pressure head 41 is driven to press down the rod guide rail 40 by pressing down the telescopic member 42, and then the sleeve 10, bushing 20, sealing ring 30 and rod guide rail 40 are assembled in place, thereby realizing the automatic installation of the guide, thereby improving the assembly efficiency of the guide, improving the assembly quality, avoiding safety risks, and reducing the intensity of manual work.

[0027] In this embodiment, the positioning sleeve rod 31 is an inverted T-shaped structure with a diameter at the upper end smaller than that at the lower end, and includes a first mating rod 32 and a second mating rod 33. The first mating rod 32 is mated with the inner hole of the sleeve 10, and the second mating rod 33 is mated with the inner hole of the bushing 20, the sealing ring 30 and the rod guide rail 40. The stepped position of the first mating rod 32 and the second mating rod 33 ensures that the rod is pressed down to the predetermined position.

[0028] In this embodiment, in order to ensure that the sealing ring 30 is pressed down to the predetermined position and prevent the sealing ring 30 from being damaged or deformed during the pressing process and unable to be detected, a positioning sleeve rod air pressure channel 34 is provided in the positioning sleeve rod 31, and the output port 35 of the positioning sleeve rod air pressure channel 34 is provided on the side wall of the second matching rod 33. After the pressure head 41 presses the sealing ring 30 into place, the sealing ring 30 just seals the output port 35, so that there is no sound of gas flowing out of the entire guide, and the entire guide is pressed into place at this time.

[0029] In this embodiment, in order to facilitate the processing and forming of the positioning sleeve rod air pressure channel 34, the positioning sleeve rod air pressure channel 34 includes an axial channel 36 and a radial channel 37. The radial channel 37 is arranged at the upper and lower ends, and the output port 35 is arranged at the upper end of the radial channel 37. The radial channel 37 is connected to the axial channel 36. The input end of the axial channel 36 at the lower end is provided with a quick-release and quick-install air pressure connector 5, which is convenient for quick connection to the external air pipe.

[0030] In this embodiment, the reciprocating platform 2 includes a support platform 21, a guide rail slider assembly 22 and a reciprocating telescopic cylinder 23. The support platform 21 is installed on two groups of guide rail slider assemblies 22 arranged on the left and right. The guide rail slider assembly 22 is installed on the frame 1. The telescopic rod of the reciprocating telescopic cylinder 23 is connected to the support platform 21, thereby driving the support platform 21 to reciprocate, and then driving the positioning sleeve rod 31 to reciprocate below the pressure head 41 and the loading position 11 of the frame 1. The positioning sleeve rod 31 is installed on the support platform 21.

[0031] In this embodiment, the pressing tooling 4 includes a mounting frame 43 that spans the guide rail slider assembly 22. The mounting frame 43 is a door-type structure. The pressing telescopic member 42 is a press installed on the upper mounting plate of the mounting frame 43. The press can be electrically, hydraulically driven or pneumatically driven. The pressing rod of the press is connected to the pressing head 41, and the pressing head 41 is detachably connected by screws.

[0032] In this embodiment, a guard plate mounting frame 24 is provided on the side of the support platform 21 close to the loading position 11 of the frame 1. The guard plate mounting frame 24 is a U-shaped structure, and a guard plate 25 is installed on the guard plate mounting frame 24. The guard plate 25 realizes physical isolation. When the pressing tool 4 is working, the force is prevented from causing the parts to be separated and injuring the staff.

[0033] This embodiment also includes a positioning sleeve proximity sensor 6 for detecting the reciprocating position of the positioning sleeve 31. The positioning sleeve sensing portion 61 of the positioning sleeve proximity sensor 6 is mounted on the positioning sleeve 31, while the positioning sleeve detection portion 62 of the positioning sleeve proximity sensor 6 is mounted below the ram 41 and positioned to one side of the positioning sleeve sensing portion 61. Only when the positioning sleeve detection portion 62 detects the positioning sleeve sensing portion 61 does the positioning sleeve 31 move below the ram 41 and align their axes with each other. Only then can the ram 41 move downward, thus avoiding press-fitting errors. Similarly, this embodiment also includes a ram proximity sensor 7 for detecting the vertical position of the ram 41. The ram sensing portion 71 of the ram proximity sensor 7 is mounted on the ram, while the ram detection portion 72 of the ram proximity sensor 7 is mounted to one side of the ram 41. The press stops its upward movement only when the ram detection portion 72 detects the ram sensing portion 71. Both the positioning sleeve proximity sensor 6 and the ram proximity sensor 7 are conventional commercially available proximity sensors.
