[0045] The supporting base 10 is assembled by supporting members and is placed on the ground, and the workpiece transfer sliding table 70 is arranged in the middle of the supporting base 10.
[0046] The side support assembly 20 includes a plurality of horizontal support members 201 and a plurality of vertical support members 202. The side support assembly 20 is arranged on one side of the support base 10. The horizontal support members 201 of the side support assembly 20 are arranged in a horizontal plane perpendicular to the moving direction of the workpiece transfer slide 70. The plurality of vertical support members 202 are arranged vertically between the plurality of horizontal support members, thereby enhancing the overall support strength of the side support assembly 20.
[0047] The tool cable support assembly 30 is used to support the cable of the tool, so that the tool can work in a larger working range without being limited by its own cable. The tool cable support assembly 30 includes a portal frame member 301, a fixed connecting rod 302, a cable support rod 303, and a hook 304. The portal frame member 301 includes two upright columns and a horizontal beam arranged between the two upright columns. The side portions of the upright columns of the portal frame member 301 are connected to the vertical support members 202 of the side support assembly 20 through the fixed connecting rod 302, and the free ends of the two upright columns of the portal frame member 301 are fixed to the support members of the support base 10. One end of the cable support rod 303 is cantilevered supported on the horizontal beam of the portal frame member 301, and the other end is provided with the hook 304 for supporting the cable.
[0048] The first tool assembly 40 is used to screw the nut on the screw rod installed on the workpiece, Figure 3 Fig. 4 is a perspective view of the first tool assembly 40, as Figure 3 shown, the first tool assembly 40 includes a horizontal transverse guide mechanism 41, a vertical guide mechanism 42, a longitudinal cantilever assembly 43, a horizontal longitudinal guide mechanism 44, a suspension support mechanism 45, a tool coaxial anti-rotation mechanism 46, and a nut mounting assembly 47.
[0049] The horizontal transverse guide mechanism 41 includes a horizontal transverse rail 411 and a plurality of sliders 412 arranged on the horizontal transverse rail 411. The horizontal transverse rail 411 is arranged on the side of the horizontal support member 201, and the plurality of horizontal support members 201 are provided with the horizontal transverse guide mechanism 41.
[0050] The vertical guide mechanism 42 includes a vertical rail 421 and a guide block 422 arranged on the vertical rail 421. Two groups of vertical guide mechanisms 42 are arranged transversely on the horizontal transverse guide mechanism 41, and the two ends of the vertical rail 421 are respectively connected to the corresponding two sliders 412 of the two groups of horizontal transverse guide mechanisms 41, so that the vertical rail 421 is arranged in a vertical direction.
[0051] The longitudinal cantilever assembly 43 comprises a slider connecting seat 431 and a cantilever member 432, wherein the slider connecting seat 431 is fixedly connected to a plurality of guide blocks 422 in the two groups of vertical guide mechanisms 42, so that the longitudinal cantilever assembly 43 can move up and down by sliding the plurality of guide blocks 422 up and down along the vertical rails 421.
[0052] The horizontal longitudinal guide mechanism 44 comprises a linear bearing and a guide rod, one end of which is connected to the cantilever member 432, and the other end is provided with a nut mounting assembly 47.
[0053] The horizontal longitudinal guide mechanism 44 is also attached with a tool coaxial anti-rotation mechanism 46, because if the bolt and nut need to be rotated relative to each other and tightened onto the workpiece during work, the bolt or nut will follow the rotation of the tool power head and cannot complete the work. By setting the tool coaxial anti-rotation mechanism, the tool coaxial anti-rotation mechanism can be manually operated to clamp the bolt or nut to prevent it from rotating with the tool power head, thereby completing the tightening work. Therefore, the tool coaxial anti-rotation mechanism 46 comprises a sliding mechanism, a handle, and a limiting block, wherein the sliding mechanism is coaxially arranged with the horizontal longitudinal guide mechanism 44. For example, during work, when used to assist in tightening the nut on the installed screw rod on the workpiece, in order to prevent the screw rod from rotating with the tightening tool, the handle is used to pull the limiting block close to the screw rod and clamp the outer hexagonal of the screw rod with the limiting block, achieving the circumferential limiting of the screw rod.
[0054] The suspension support mechanism 45 comprises a counterweight assembly 451 and a suspension bracket 452, the suspension bracket 452 is L-shaped and comprises a vertical support part and a protruding suspension part, the vertical support part is arranged parallel to the vertical rails 421 of the vertical guide mechanisms 42, one end of which is fixed to the horizontal support member 201 and arranged centrally between the two groups of vertical guide mechanisms 42.

The suspension rope end of the counterweight assembly 451 (also known as a pneumatic hoist) is attached to the cantilever member by a hook ring, and by pre-setting the balance, the weight support of all moving mechanisms is achieved.
[0055] The nut mounting assembly 47 is a matching tool for tightening nuts, which is a commonly used tool assembly in the art and will not be described here.
[0056] The second tool assembly 50 is used for tightening vertical screw rods, and the second tool assembly 50 comprises a horizontal transverse guide mechanism, a vertical guide mechanism, a longitudinal cantilever assembly, a horizontal longitudinal guide mechanism, a suspension support mechanism, and a screw rod mounting assembly. The horizontal transverse guide mechanism, the vertical guide mechanism, the longitudinal cantilever assembly, the horizontal longitudinal guide mechanism, and the suspension support mechanism are arranged similarly to the corresponding parts in the first tool assembly 40, but the second tool assembly 50 does not have a tool coaxial anti-rotation mechanism, because the screw rod is directly tightened onto the workpiece body, so it does not have a tool coaxial anti-rotation mechanism.
[0057] The screw mounting assembly is a matched tool for screwing the screw, which is a commonly used tool assembly in the art and will not be described here.
[0058] The tool return mechanism 60 comprises a return bracket and a return confirmation switch. The return confirmation switch can be triggered when the tool assembly is manually moved to the initial position, and when the return confirmation switch is triggered, it transmits a signal to the relevant automatic equipment to proceed to the next process. The tool return mechanism limits the automatic movement of the tool assembly by a mechanical mechanism, preventing interference between different tool assemblies or between the tool assembly and the automatic equipment such as the sliding table.
[0059] The workpiece moving sliding table 70 is used to move the workpiece, comprising a sliding table bracket, guide rails, a driving cylinder, a drag plate, and a workpiece positioning and clamping mechanism. The sliding table bracket is mounted on the support base 10, and guide rails are mounted on both sides of the sliding table bracket. The drag plate is mounted on the sliding table bracket through the guide rails and is driven by the driving cylinder. The workpiece positioning and clamping mechanism is mounted on the drag plate and is used to position and clamp the workpiece.
[0060] The tool assembly is connected to the vertical guide mechanism of the horizontal and transverse guide mechanism through the longitudinal cantilever assembly, which can increase the tool overhang distance and also improve the carrying capacity.
[0061] It can be understood by those skilled in the art that the above description is only a preferred embodiment of the present application and is not intended to limit the present application.
