An upper positioning cylinder 9 is provided, with an upper positioning block 10 that can rise and fall with the piston of the upper positioning cylinder 9. A set of rotatable positioning rollers 11 are provided at the bottom of the upper positioning block 10. The outer ring of the positioning rollers 11 has an upper positioning groove adapted to the straight steel pipe 28, allowing the positioning rollers 11 to roll on the straight steel pipe 28. A guide channel is provided inside the positioning platform 2, and a positioning hole communicating with the guide channel is opened on the left side wall of the mounting groove 5 of the base plate 27. A guide block 12 that can move left and right along the guide channel is provided inside the guide channel. The piston of the side positioning cylinder 3 is connected to the guide block 12. A retractable positioning rod 13 is provided on the side of the guide block 12 away from the side positioning cylinder 3. The positioning rod 13 is adapted to the center hole of the base plate 27, the inner ring of the straight steel pipe 28, and the positioning hole. The top of the positioning rod 13 is formed with a conical frustum 29 adapted to the inner ring of the straight steel pipe 28. The conical frustum 29 plays a positioning and guiding role during the press-fitting process.
[0021] The guide block 12 has a spring hole on the side opposite to the positioning cylinder 3, and a spring 14 is installed in the spring hole. One end of the positioning rod 13 is connected to the spring 14, and the other end is adapted to the positioning hole. In order to better control the movement of the positioning rod 13, the guide channel can be multi-segmented, with one end adapted to the guide block 12 and the other end adapted to the positioning rod 13.
[0022] The specific structures and corresponding control systems of the side positioning cylinder 3, the upper positioning cylinder 9, and the pressing cylinder 6 are not innovative points of this case. Those skilled in the art can flexibly select and implement them according to existing technologies and needs. Therefore, they will not be elaborated here.
[0023] The bottom of the inner sidewalls on both the front and rear sides of the base plate mounting groove 5 are provided with positioning grooves 15 that are compatible with the base plate 27. The overall cross-section of the positioning groove 15 and the base plate mounting groove 5 is T-shaped. The positioning groove 15 and the base plate mounting groove 5 are integrally formed.
[0024] The lower positioning structure includes a first positioning plate 16 disposed on the right side of the positioning platform 2, and a second positioning plate 17 disposed on the right side of the first positioning plate 16. The upper surfaces of the first positioning plate 16 and the second positioning plate 17 are both formed with a lower positioning groove 4.
[0025] The lower positioning structure also includes two straight steel pipe positioning slide rails 18 arranged on the right side of the positioning platform 2. The two straight steel pipe positioning slide rails 18 are arranged in parallel, and guide grooves 19 are provided at the bottom of the side wall of the two straight steel pipe positioning slide rails 18 on opposite sides. The first positioning plate 16 and the second positioning plate 17 are arranged between the two positioning slide rails. The bottom of the front and rear sides of the first positioning plate 16 and the second positioning plate 17 are formed with guide bosses 20 that are compatible with the guide grooves 19. The first positioning plate 16 and the second positioning plate 17 can move left and right along the two straight steel pipe positioning slide rails 18.
[0026] As for whether additional structures are needed to cooperate with the first positioning plate 16 and the second positioning plate 17, since this is not an innovation of this case, it will not be elaborated here. Those skilled in the art can flexibly select and implement them as needed.
[0027] The base 1 is provided with a press-fit guide rail 26 on the front and rear sides of the straight steel pipe positioning slide rail 18, and the two press-fit guide rails 26 are arranged in parallel. Each press-fit guide rail 26 is provided with a guide slider 24 that can slide along it. The two guide sliders 24 are supported by a press-fit positioning plate 25 that can move left and right with them. The press-fit plate 7 is formed on the press-fit positioning plate 25.
[0028] The base 1 has four support feet 21 at its bottom corners. The upper surface of the base 1 has a side positioning seat 22 and a rear positioning seat 23. The positioning platform 2 is set on the side positioning seat 22. The cylinder part of the press-fit cylinder 6 is set on the rear positioning seat 23.
[0029] During operation: According to the size of the straight steel pipe 28, adjust the distance between the first positioning plate 16 and the second positioning plate 17, and place the straight steel pipe 28 to be assembled in the lower positioning groove 4 on the first positioning plate 16 and the second positioning plate 17; put the base plate 27 into the base plate placement groove 5 through the opening on the upper end face of the base plate placement groove 5 on the positioning platform 2.
[0030] The side positioning cylinder 3 drives the guide block 12 to move, and the guide block 12 drives the compression spring 14 and positioning rod 13 on it to move until the positioning rod 13 extends out of the assembly hole of the base plate 27 to position the base plate 27.
[0031] At the same time, the upper positioning cylinder 9 works, driving the upper positioning block 10 of its piston part to descend, and the positioning roller 11 presses down on the straight steel pipe 28. Then, the press-fit cylinder 6 operates, driving the press-fit positioning plate 25 to move. The press-fit plate 7 on the press-fit positioning plate 25 applies a force to the straight steel pipe 28, pushing the straight steel pipe 28 towards the base plate mounting groove 5. Due to the setting of the conical frustum 29, the end of the straight steel pipe 28 near the conical frustum 29 will be fitted onto the conical frustum 29, aligning the straight steel pipe 28 with the mounting hole of the base plate 27. Then, the straight steel pipe 28 will apply a force to the positioning rod 13 through the conical frustum 29. The positioning rod 13 will compress the compression spring 14 and move in a direction away from the straight steel pipe 28 until the straight steel pipe 28 is completely press-fitted into the base plate 27.
[0032] The piston of the side positioning cylinder 3 retracts, causing the positioning rod 13 to retract until the conical frustum 29 on the positioning rod 13 is completely separated from the straight steel pipe 28. The piston of the upper positioning cylinder 9 rises, the positioning roller 11 rises, and the piston of the pressing cylinder 6 drives the pressing plate 7 to return to its original position. The assembled base plate 27 containing the straight steel pipe 28 is then manually removed from the opening of the base plate mounting groove 5 located on the upper end face of the positioning platform 2.
