Description

[0002] A jack is a small and light lifting equipment that uses a rigid lifting piece as a working device and can lift heavy objects within a small stroke of a top support or a bottom support claw. Jacks are mainly used in factories, mines, transportation and other departments for vehicle repair and other lifting and supporting work. There are many types and categories of jacks, each type is suitable for different applications and needs. Among them, vertical jacks are the most widely used type of jacks. Vertical jacks are mainly composed of a base, a main column, a lifting mechanism, a safety locking device, a handle and other parts. The base and the main column need to be welded together during the processing of the jack.

[0003] The traditional welding method requires clamping the base and the main column separately, then connecting the two together, and then welding the connection between the base and the main column. Since the clamping and connecting steps are performed separately, it is easy to cause slight changes in the position and angle of the parts.

Moreover, the welding direction needs to be adjusted multiple times during welding to weld the four directions of the connection between the two, which further increases the complexity of the welding steps. The various steps in the welding are scattered and independent, which easily increases the operation time and reduces the overall welding efficiency. Summary of the invention

[0029] See also Figure 1 and Figure 2The present invention provides a technical solution: a jack metal component welding processing equipment, including a processing seat 1, the upper end surface of the processing seat 1 is fixedly connected with a driving ring 2 through a pillar, the upper part of the driving ring 2 is rotatably connected with an annular disk 3, a plurality of clamping parts 4 for placing and automatically clamping the main column assembly of the jack are equidistantly installed on the annular disk 3 in the circumferential direction, a top pressure guide part 5 for cooperating with the clamping part 4 so as to touch the jack base assembly so that it is tightly connected with the main column assembly is arranged on the upper part of the processing seat 1, a self-moving mechanism 6 for moving the welded jack assembly out is jointly arranged between the clamping part 4 and the processing seat 1, a longitudinal welding mechanism 7 for longitudinal welding of the jack assembly is installed on the upper part of the processing seat 1 and above the annular table, and a transverse welding mechanism 8 for transverse welding of the jack assembly is installed on the right part of the processing seat 1.

[0030] See also Figure 2 , Figure 3 and Figure 4 In this embodiment, the clamping portion 4 includes a mounting groove 41 provided on the annular disk 3, a placement plate 42 is hinged between the groove walls on opposite sides of the mounting groove 41 through a rotating column, arc grooves 43 are provided on the groove walls on opposite sides of the mounting groove 41, a sliding column 44 slidably provided in the arc groove 43 is fixedly connected to the side of the placement plate 42 close to the arc groove 43, a cross bar 45 is fixedly connected to the side of the placement plate 42 close to the mounting groove 41 through a reset spring, and the ends of the two cross bars 45 are fixedly connected to L-shaped clamping plates 46 penetrating and connected to the placement plate 42, a notch ring 47 with a rear opening is fixedly connected to the upper end surface of the processing seat 1 through a fixing rod, and a driving component 48 for driving the L-shaped clamping plate 46 to move so as to clamp the main column is jointly provided between the notch ring 47 and the cross bar 45.

[0031] See also Figure 3 and Figure 4 The driving assembly 48 includes a rectangular plate 481 fixedly connected to the lower end surface of the cross bar 45 through a connecting rod, and an inclined groove 482 is opened on the rectangular plate 481. Sliding columns 483 are slidably connected in the two inclined grooves 482. The two sliding columns 483 are fixedly connected to a T-shaped rod 484 on the outside. An arc-shaped pressure ring 485 is fixedly connected to the lower end surface of the notch ring 47. A pulling column 486 that contacts the lower part of the arc-shaped pressure ring 485 is fixedly connected to the side of the vertical section of the T-shaped rod 484 close to the arc-shaped pressure ring 485. The inclined groove 482 gradually inclines from bottom to top toward the side close to the vertical section of the T-shaped rod 484.

[0032] See also Figure 1 and Figure 7 In this embodiment, the top pressure guiding part 5 includes an arc-shaped pressure plate 51 fixedly connected to the upper end surface of the processing seat 1 through a connecting column. The arc-shaped pressure plate 51 is sleeved on the outside of the annular disk 3. An arc-shaped inclined surface is opened on the left part of the inner surface of the arc-shaped pressure plate 51, and an arc-shaped support plate 52 is fixedly connected to the lower end surface of the arc-shaped pressure plate 51.

[0033] During welding, the main column is placed in the mounting groove 41 on the left, so that it is placed on the placement plate 42, and then the base is placed on the arc-shaped support plate 52 on the left, so that the left end of the main column and the mounting opening on the base are initially inserted together, and then the driving ring 2 controlled by the self-driven force drives the annular disk 3 to rotate counterclockwise, and the annular disk 3 then drives the main column to rotate, and the main column then drives the base to rotate synchronously. During the counterclockwise rotation of the base in the arc-shaped support plate 52, it will be squeezed by the arc-shaped inclined surface on the inner surface wall of the left part of the arc-shaped pressure plate 51 and then move toward the direction close to the main column, so that the base and the main column are tightly connected together.

[0034] During the circumferential rotation of the annular disk 3, the pull column 486 initially abutting against the lower surface of the notch ring 47 will be driven to gradually move and abut against the lower surface of the arc-shaped pressure ring 485. During the process of sliding from the lower part of the notch ring 47 to the lower part of the arc-shaped pressure ring 485, the pull column 486 will be pressed downward. The pull column 486 then drives the sliding column 483 downward through the T-shaped rod 484. During the downward movement of the sliding column 483, it squeezes the inclined groove 482 to make the rectangular plates 481 move closer to each other. The rectangular plates 481 then drive the cross bar through the connecting rod. 45 moves, and the two cross bars 45 are driven to move closer to each other, and the cross bar 45 then drives the L-shaped clamping plate 46 to move closer to the placement plate 42 until the vertical section of the L-shaped clamping plate 46 touches the main column, thereby completing the clamping and limiting of the main column, and then the annular disk 3 drives the clamped main column to rotate circumferentially through the longitudinal welding mechanism 7 and the transverse welding mechanism 8 in turn to weld the connection between the main column and the base, and finally moves to the self-removing mechanism 6 to automatically eject and remove the welded main column.

[0035] Clamping is performed while docking to ensure that the main column and base are in a stable and correct position before welding, reducing welding deviations caused by part displacement. Automatic docking and clamping are completed in the same process, which also avoids error accumulation between independent steps and improves the overall docking and welding accuracy.

[0036] See also Figure 1 , Figure 2 , Figure 5 and Figure 6In this embodiment, the longitudinal welding mechanism 7 includes a shaft rod 71 fixedly connected to the upper end surface of the processing seat 1, the shaft rod 71 is rotatably connected to a mounting ring 72, the mounting ring 72 and the shaft rod 71 are fixedly connected to a torsion spring 73, the mounting ring 72 is fixedly connected to a C-shaped frame 74 through a bearing rod, the C-shaped frame 74 is rotatably connected to a gear 75, the C-shaped frame 74 is slidably connected to two racks 76 respectively meshing with the gear 75, the front end surface of the rack 76 on the left is fixedly connected to an L-shaped plate 77, and the right side of the rack 76 on the right is fixedly connected to There is a folding plate 78, and a No. 1 welding head 79 is respectively arranged on the opposite sides of the L-shaped plate 77 and the folding plate 78. A limiting spring 710 is fixedly connected between the folding plate 78 and the C-shaped frame 74. An arc-shaped wedge plate 711 is fixedly connected to the outside of the shaft rod 71 through a fixed column. A push column 712 that cooperates with the arc-shaped wedge plate 711 is fixedly connected to the side of the folding plate 78 close to the center of the annular disk 3. The horizontal welding mechanism 8 includes an F-shaped frame 81 fixedly connected to the right part of the upper end face of the processing seat 1, and a No. 2 welding head 82 is respectively arranged on the opposite sides of the transverse section of the F-shaped frame 81.

[0037] When the annular disk 3 drives the clamped main column to rotate circumferentially and passes through the longitudinal welding mechanism 7, the side of the main column will touch the folding plate 78, and then push the folding plate 78 to move circumferentially synchronously. During the circumferential movement of the folding plate 78, the push column 712 will be driven to move and contact the inclined surface of the arc-shaped wedge plate 711. The inclined surface of the arc-shaped wedge plate 711 squeezes the column push column 712 to move up, and the push column 712 then drives the folding plate 78 to move up. The folding plate 78 then drives the rack 76 on the right to rise. The rising of the rack 76 on the right drives the gear 75 to rotate. The rotation of the gear 75 then drives the rack 76 on the left to move downward. The rack 76 on the left then drives the L-shaped plate 77 to move downward. The folding plate 78 and the L-shaped plate 77 move toward each other, and then respectively drive the No. 1 welding plate on the right The joint 79 moves from bottom to top and the No. 1 welding head 79 located on the left moves from top to bottom. During the longitudinal movement of the two No. 1 welding heads 79 toward each other, the left and right sides of the joint between the main column and the base can be welded. After the left and right sides of the joint are welded, the folding plate 78 rises to a height higher than the main column. Then, the main column passes over the folding plate 78 and continues to move circumferentially (the torsion spring 73 drives the mounting ring 72 to reverse and reset clockwise, and the mounting ring 72 then drives the C-shaped frame 74 to reverse through the load-bearing rod, and the C-shaped frame 74 then drives the folding plate 78 to reverse and move, so that the push column 712 gradually moves down from the arc-shaped wedge plate 711. At the same time, the compressed limit spring 710 pushes the folding plate 78 downward, so that the folding plate 78 moves down and resets to the initial position).

[0038] As the main column moves to the horizontal section of the F-shaped frame 81 after the annular disk 3 continues to rotate, the No. 2 welding head 82 is controlled to operate to weld the upper and lower sides of the connection between the main column and the base, and multi-sided welding is completed at the same time. At the same time, the opposite sides are welded, which eliminates the steps of repeatedly adjusting the position of parts in traditional welding, greatly reduces the operation time, and improves the welding efficiency. In addition, the welding method of welding opposite sides at the same time can also make the heat distribution more uniform, reduce the concentration of thermal stress, and improve the strength and durability of the weld. The balanced welding heat input reduces the deformation of the parts during the welding process, ensuring the stability of the shape of the assembly after welding.

[0039] See also Figure 4 In this embodiment, the self-moving mechanism 6 includes an arc-shaped protrusion 61 fixedly connected to the rear part of the upper end surface of the notch ring 47, and a top column 62 for cooperating with the arc-shaped protrusion 61 is fixedly connected to the lower end surface of the placement plate 42. The arc-shaped protrusion 61 is located directly above the rear part of the notch ring 47. After the welding of the main column and the base is completed, the annular disk 3 drives it to move to the rear part. In the process of the annular disk 3 driving the clamping part 4 that clamps the main column to gradually move to the rear part: the pulling column 486 will be driven to gradually move out from the lower part of the arc-shaped pressure ring 485 and then move to the rear opening position of the notch ring 47. In the process of moving the pulling column 486 out from the lower part of the arc-shaped pressure ring 485, the pulling column 486 will gradually lose the downward pull on the T-shaped rod 484, and then the T-shaped rod 484 controls the sliding column 483 to stop squeezing the inclined groove 482, and then the sliding column 483 is re-engaged. The reset spring extends and pushes the cross bar 45 to move away from the placement plate 42. The cross bar 45 then drives the L-shaped clamping plate 46 to move synchronously, so that the L-shaped clamping plate 46 is separated from the main column. Then the annular disk 3 drives the top column 62 to move and contact the arc-shaped protrusion 61. The arc-shaped protrusion 61 pushes the top column 62 to rise. The top column 62 then pushes the placement plate 42 to rotate around the rotating column. The sliding column 44 slides in the arc-shaped groove 43, so that the placement plate 42 becomes an inclined state with the side close to the shaft rod 71 higher and the side close to the shaft rod 71 lower. Subsequently, the welded main column can automatically slide backward and move out under the action of the inclined surface of the placement plate 42, reducing manual operation, reducing operating difficulty and labor intensity. The automatic removal process reduces the direct contact of the operator and improves operating safety.

[0040] During operation, the main column is first placed in the clamping part 4 located on the left, and then the base is placed in the top pressure guide part 5, so that the main column and the base are preliminarily connected together, and then the annular disk 3 is driven to rotate by controlling the operation of the driving ring 2. During the rotation of the annular disk 3, the top pressure guide part 5 is triggered to operate, so that the base and the main column are tightly connected together. At the same time, the clamping part 4 will also be triggered to operate, and the moving main column will be clamped and limited synchronously. The annular disk 3 drives the main column and the base after clamping and docking to continue to move circumferentially, and will pass through the longitudinal welding mechanism 7 and the transverse welding mechanism 8 in succession, and can respectively weld the left and right sides and the upper and lower sides of the connection between the main column and the base. Finally, the main column and the base welded together will be triggered when the annular disk 3 moves to the rear, and the self-moving mechanism 6 will be operated, so that the welded components can be removed, which is convenient for the continuous welding processing of the jack assembly.
