Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] Embodiment 1

[0024] Please refer to Figures 1-6 , the present utility model provides the following technical solutions: A joint pressing device includes a positioning table 1, an observation assembly 5 is arranged on the side wall of the positioning table 1, a positioning collar 3 is connected below the positioning table 1, pressing mechanisms 4 are arranged on both sides of the positioning collar 3 and below the positioning table 1, a driving mechanism 2 is arranged between the pressing mechanism 4 and the positioning table 1, a plurality of pressing mechanisms 6 are arranged on the inner side wall of the positioning collar 3, and a supporting and positioning assembly 7 is arranged inside the pressing mechanism 4 and between two adjacent pressing mechanisms 6.

[0025] Specifically, the observation component 5 includes an L-shaped transparent plate 51, a scale 52, a mounting groove 53, and a fixing groove 54. Mounting grooves 53 are provided at both ends on one side of the positioning table 1. A scale 52 is arranged inside the mounting groove 53. An L-shaped transparent plate 51 is arranged inside the mounting groove 53 and on one side of the scale 52. Fixing grooves 54 are provided on the side wall of the mounting groove 53 at positions corresponding to the L-shaped transparent plate 51.

[0026] By adopting the above technical solution, after placing the scale 52 inside the mounting groove 53, and then placing the L-shaped transparent plate 51 inside the mounting groove 53 and the fixing groove 54 and making it fit against the outer side wall of the scale 52, during subsequent use, the operator can observe the scale lines on the scale 52 through the L-shaped transparent plate 51, which is convenient for the operator to observe. Moreover, under the action of the L-shaped transparent plate 51, it can prevent dust and other impurities in the external environment from falling onto the scale 52, avoiding contamination of the scale 52, and can prevent friction between the press-fitting mechanism 4 and the scale 52 during movement, thereby preventing wear of the scale lines on the scale 52.

[0027] Specifically, the observation component 5 further includes a fixing cylinder 55 and a fixing screw 56. A fixing screw 56 is connected to the inner wall of the fixing groove 54. A through hole is provided on the L-shaped transparent plate 51 at a position corresponding to the fixing screw 56. A fixing cylinder 55 is connected to the outer side wall of the fixing screw 56 and on one side of the L-shaped transparent plate 51.

[0028] By adopting the above technical solution, after passing the L-shaped transparent plate 51 through the fixing screw 56 and placing it inside the mounting groove 53 and the fixing groove 54, and then threadedly connecting the fixing cylinder 55 to the outer side wall of the fixing screw 56, under the action of the fixing cylinder 55 and the fixing screw 56, the L-shaped transparent plate 51 can be limited and fixed, facilitating the disassembly and assembly operations of the L-shaped transparent plate 51.

[0029] Specifically, one end of the L-shaped transparent plate 51 is connected with a plug-in column, and a plug-in groove is provided on the inner side wall of the mounting groove 53 at a position corresponding to the plug-in column.

[0030] By adopting the above technical solution, during the process of passing the L-shaped transparent plate 51 through the fixing screw 56 and placing it inside the mounting groove 53 and the fixing groove 54, the plug-in column is inserted into the plug-in groove accordingly. Under the plug-in action of the plug-in column and the plug-in groove, the L-shaped transparent plate 51 and the mounting groove 53 can be preliminarily plugged together.

[0031] When this embodiment is in use, place the scale 52 inside the installation groove 53, pass the L-shaped transparent plate 51 through the fixing screw 56 and place it inside the installation groove 53 and the fixing groove 54, and then thread the fixing cylinder 55 onto the outer wall of the fixing screw 56. Under the action of the fixing cylinder 55 and the fixing screw 56, the L-shaped transparent plate 51 can be limited and fixed, and then the scale 52 can be limited and fixed. Then, pre-install the pipe joint in the positioning collar 3, and use the tightening mechanism 6 to perform a tightening operation on the pipe joint. Subsequently, pass the two pipe bodies to be connected through the two pressing mechanisms 4 on both sides and extend them into the pipe joint, so that the pipe body and the pipe joint are pre-installed and connected. Then, drive the pressing mechanism 4 to move by using the driving mechanism 2 on the positioning table 1. During the movement of the pressing mechanism 4, the operator can observe the scale line on the scale 52 through the L-shaped transparent plate 51 to judge the moving distance of the pressing mechanism 4. When the pressing head component on the pressing mechanism 4 moves to the overlapping position of the connecting pipe body and the pipe joint, then use the pressing mechanism 4 to perform a pressing operation on the pipe joint and the connecting pipe body;

[0032] Embodiment 2

[0033] The difference between this embodiment and Embodiment 1 is that the support positioning assembly 7 includes a support rod 71, a fixing sleeve 72, a connecting spring 73 and a support plate 74. A fixing sleeve 72 is connected inside the pressing mechanism 4 and between two adjacent tightening mechanisms 6. A support rod 71 is inserted into the fixing sleeve 72. A connecting spring 73 is connected between the support rod 71 and the pressing mechanism 4 and inside the driving mechanism 2. One end of the support rod 71 away from the connecting spring 73 is connected to a support plate 74. A rubber pad is connected to one side of the support plate 74 away from the support rod 71.

[0034] Specifically, a limit slider is connected to one end of the support rod 71 close to the connecting spring 73, and a limit chute is provided on the inner side wall of the fixing sleeve 72 at a position corresponding to the limit slider.

[0035] By adopting the above technical solution, the movement of the support rod 71 drives the limit slider to move inside the limit chute. When the limit slider fits against the side wall of the limit chute, the limit chute prevents the limit slider from continuing to move, and thus can prevent the support rod 71 from moving and avoid the support rod 71 from detaching from the fixing sleeve 72.

[0036] When this embodiment is in use, when the pipe joint is pre-installed inside the positioning collar 3, the support plate 74 moves under the extrusion of the pipe joint. The movement of the support plate 74 drives the support rod 71 to move inside the fixing sleeve 72. The support rod 71 moves and squeezes the connecting spring 73, causing it to deform. Under the action of multiple support plates 74, the pipe joint can be preliminarily supported and positioned, which is convenient for the operator to subsequently use the tightening mechanism 6 to perform a tightening operation on the pipe joint.

[0037] The structure and principle of the driving mechanism 2 composed of an adjustment area, a threaded rod, a threaded block, an adjustment motor, a linkage platform, and a pointer in the present utility model have been disclosed in the pipe joint pipe pressing mechanism disclosed in Chinese Patent Application No. 202220788169.8. Its working principle is as follows: The adjustment areas are symmetrically opened on both sides of the lower surface of the positioning table 1. The adjustment motors are installed on both side walls of the positioning table 1. The threaded rod is rotatably installed in the adjustment area through bearings and is in transmission connection with the adjustment motor. The threaded block is sleeved outside the threaded rod by screw threads and is in sliding fit with the inner wall of the adjustment area. The linkage platform is locked and installed on the lower surface of the threaded block. One end above the linkage platform is connected with a pointer. A pressing mechanism 4 is arranged below the linkage platform. During use, the adjustment motor is used to drive the threaded rod to rotate, and then the threaded block can be driven to move inside the adjustment area. The movement of the threaded block drives the linkage platform to move, and then the pressing mechanism 4 and the pointer can be driven to move.

[0038] The structure and principle of the pressing mechanism 4 composed of a pressing sleeve ring, an inner wall slide rail, a sliding table, a hydraulic press, a pressing head, an outer wall gear ring, and an electric gear in the present utility model have been disclosed in the pipe joint pipe pressing mechanism disclosed in Chinese Patent Application No. 202220788169.8. Its working principle is as follows: The pressing sleeve ring is locked and installed on the lower surface of the driving mechanism 2. The inner wall slide rail is opened in the middle of the inner wall of the pressing sleeve ring. Four sliding tables are evenly and slidably installed on the inner wall of the pressing sleeve ring and are engaged with the inner wall slide rail. The hydraulic press is locked and installed in the middle of the inner wall of the sliding table. The pressing head is correspondingly assembled at the output end of the hydraulic press. Two outer wall gear rings are symmetrically welded at the two side edges of the pressing sleeve ring. The electric gear is correspondingly locked and installed on both sides of the outer walls of the four sliding tables through brackets, and the electric gear is in meshing transmission connection with the outer wall gear ring. During use, the electric gear is used to mesh and drive with the outer wall gear ring to make the sliding table rotate inside the inner wall slide rail to adjust the position of the sliding table, and then the hydraulic press is started to push the pressing head to move forward inside the pressing sleeve ring. The pipe joint is extruded by the pressing head to generate a certain deformation, realizing the rapid positioning of the pipe body inserted into the pipe joint and enabling the rapid pressing connection of the pipe joint and the pipe body.

[0039] The structure and principle of the pressing mechanism 6 composed of a positioning cylinder and a positioning pressing plate in the present utility model have been disclosed in the pipe joint pipe pressing mechanism disclosed in Chinese Patent Application No. 202220788169.8. Its working principle is as follows: Four positioning cylinders are evenly distributed on the inner wall of the positioning sleeve ring 4. The positioning pressing plate is installed at the output end of the positioning cylinder. An arc-shaped positioning groove is opened on the surface of the positioning pressing plate, and an anti-slip pad covers the surface of the positioning pressing plate. During use, the positioning cylinder is used to drive the positioning pressing plate to move, and the positioning pressing plate is used to press against the pipe joint inserted into the positioning sleeve ring 4.

[0040] Working principle and usage process of the utility model: The utility model places the scale 52 inside the installation groove 53, passes the L-shaped transparent plate 51 through the fixing screw 56 and places it inside the installation groove 53 and the fixing groove 54, and then threadedly connects the fixing cylinder 55 to the outer wall of the fixing screw 56. Under the action of the fixing cylinder 55 and the fixing screw 56, the L-shaped transparent plate 51 can be limited and fixed, and thus the scale 52 can be limited and fixed. Then, the pipe joint is pre-installed in the positioning collar 3. When the pipe joint is pre-installed inside the positioning collar 3, the support plate 74 moves under the extrusion of the pipe joint. The movement of the support plate 74 drives the support rod 71 to move inside the fixed sleeve 72, and the support rod 71 moves to squeeze the connecting spring 73, causing it to deform. Under the action of multiple support plates 74, the pipe joint can be initially supported and positioned, facilitating the subsequent tightening operation of the pipe joint by the tightening mechanism 6. Then, the tightening mechanism 6 is used to tighten the pipe joint. Subsequently, the two pipe bodies to be connected are passed through the pressing mechanisms 4 on both sides and extended into the pipe joint, so that the pipe bodies are pre-installed and connected to the pipe joint. Then, the driving mechanism 2 on the positioning table 1 is used to drive the pressing mechanism 4 to move. During the movement of the pressing mechanism 4, the operator can observe the scale lines on the scale 52 through the L-shaped transparent plate 51 to judge the moving distance of the pressing mechanism 4. When the pressing head component on the pressing mechanism 4 moves to the overlapping position of the connecting pipe body and the pipe joint, the pressing mechanism 4 is used to press the pipe joint and the connecting pipe body.
