Description

Technical Field

[0001] The invention relates to the field of ship hull construction, in particular to a fixing tool for assembling outer plates. Background Art

[0002] When assembling each row of outer plates on the tire frame, the base plate must first be positioned on the tire frame, and then the outer plates are assembled in sequence. Since welding deformation is easily generated when the outer plates are welded, the outer plate curve does not meet the requirements. In order to prevent welding deformation, horse plates are usually used for fixation. However, when horse plates are used to control deformation, not only a large amount of welding work needs to be carried out during the outer plate assembly process, but also the horse plates need to be removed after the outer plate assembly is completed, and the horse plate weld feet on the outer plate need to be polished, which greatly increases the workload of outer plate assembly and is not conducive to the rapid assembly of outer plates. Summary of the Invention

[0003] In view of the shortcomings of the prior art described above, the technical problem to be solved by the present invention is to provide a fixing tool for assembling outer panels, which can replace the existing horse plates to fix the outer panels without welding, effectively avoiding the horse plate welding, removal and weld foot grinding work caused by traditional horse plate fixing, and improving the assembly efficiency of the outer panels.

[0004] The present invention provides a fixing tool for assembling outer panels, comprising a base, a height adjustment device and a fixing device; the height adjustment device is installed on the base and is used to adjust the height position of the fixing device; the fixing device comprises a bottom plate, a support tube, a lifting rod and two switch-type magnetic seats; the bottom plate is installed on the height adjustment device, and the lateral angle of the bottom plate can be adjusted and locked; the two switch-type magnetic seats are arranged at intervals on the top of the bottom plate along the lateral direction, and are used to respectively adsorb two outer panels to be assembled; the support tube is located between the two switch-type magnetic seats, and the lateral position of the support tube on the bottom plate is adjustable; the lifting rod is threadedly installed on the support tube, and the height of the lifting rod extending out of the top of the support tube is adjustable; the position of the outer outer panel is adjusted by adjusting the extended height of the lifting rod, so that the two outer panels are smoothly docked. The present invention utilizes two switch-type magnetic seats to adsorb and fix the two outer panels to be assembled, and adjusts the position of the outer outer panel by screwing the lifting rod, so that the longitudinal plate seams of the two outer panels are smoothly connected to ensure that the curvature of the outer panels after welding meets the requirements; since there is no need to perform plate welding, cutting and weld foot grinding during the entire operation process, the outer panel assembly efficiency is improved and the outer panel assembly cycle is shortened.

[0005] Preferably, the outer plate is provided with a transverse through-slot for the lower end of the jacking rod to pass through, so as to expand the jacking stroke of the jacking rod.

[0006] Preferably, a handle is provided at the lower end of the jacking rod to reduce the difficulty of the staff in screwing the jacking rod.

[0007] Preferably, the fixing tool for assembling the outer panel includes a flexible bent rod; there are two height adjustment devices, and the two height adjustment devices are arranged at intervals along the longitudinal direction; the two height adjustment devices are respectively connected to the two ends of the flexible bent rod, for adjusting the height position and curvature of the flexible bent rod; there are multiple fixing devices, and each fixing device is arranged on the flexible bent rod at intervals through a support rod; the top end of the support rod is fixedly connected to the bottom plate of the fixing device, and the lower part of the support rod is rotatably set on the flexible bent rod to adjust the lateral angle of the bottom plate; the rotation angle of the support rod can be locked; because the present invention can move the fixing devices required for assembling two outer panels into the tire frame at one time, the arrangement time of the fixing devices is reduced, thereby improving the fixing efficiency.

[0008] Preferably, the support rod is mounted on the flexible bent rod by an adjusting bolt; a through hole a is provided at the lower portion of the support rod, and a threaded hole a is provided on the flexible bent rod that cooperates with the through hole a, and the adjusting bolt passes through the through hole a and cooperates with the threaded hole a to achieve adjustment and locking of the angle of the support rod; when adjusting the angle of the support rod, it is necessary to first loosen the adjusting bolt (that is, the nut of the adjusting bolt moves in a direction away from the flexible bent rod) until the support rod can move and rotate axially on the adjusting bolt, and then rotate the support rod and the fixing device thereon together at a preset angle, and finally, make the support rod abut against the flexible bent rod, and tighten the adjusting bolt until the nut of the adjusting bolt cooperates with the flexible bent rod to clamp the support rod, thereby preventing relative movement between the support rod and the flexible bent rod.

[0009] Preferably, a fixed plate is provided on the top of the base plate, and the fixed plate is located between the two switch-type magnetic seats; a plurality of slots are arranged on the fixed plate at intervals along the transverse direction, and two adjacent slots are connected through a transverse guide groove; the slot is used to clamp the support tube, and the transverse guide groove is used to guide the lifting rod to move between the slots; by placing the support tube in different slots, the transverse position of the support tube can be adjusted.

[0027] When two outer panels are assembled and welded on a tire frame, horse plates are usually used to fix the two outer panels to be assembled so as to tighten the outer panel areas on both sides of the longitudinal butt joint on the tire frame (that is, a row of horse plates fixed to the tire frame are welded on the outer panels on both sides of the longitudinal butt joint) to prevent deformation of the two outer panels during butt welding. Moreover, after the outer panels are assembled and welded, the welded horse plates need to be removed and polished. Therefore, using horse plates to fix the outer panels not only involves a large amount of horse plate welding, cutting, and polishing, which increases the workload, but also easily damages the outer panels and causes subsequent rework, which greatly affects the efficiency of outer panel assembly. Based on this, the present invention provides a new fixing tool for outer panel assembly, which is used to replace horse plates to fix the outer panels to avoid a large amount of work and outer panel damage caused by horse plate fixing. For the convenience of description, in the following embodiments, the definitions of each direction are as follows: the length direction of the outer panel is defined as the front-to-back direction (that is, the longitudinal direction), the width direction of the outer panel is defined as the left-to-right direction (that is, the transverse direction), and the thickness direction of the outer panel is defined as the up-down direction.

[0028] Example

[0029] like Figure 1 、 Figure 2 、 Figure 6As shown, this embodiment provides a fixing tool for assembling outer panels, comprising a base 1, a height adjustment device 2 and a fixing device 3; wherein,

[0030] The height adjustment device 2 is installed on the base 1 and is used to adjust the height of the fixing device 3;

[0031] The fixing device 3 includes a base plate 31, a support tube 33, a lifting rod 34 and two switch-type magnetic seats 32; the base plate 31 is installed on the height adjustment device 2, and the lateral angle of the base plate 31 can be adjusted and locked; the two switch-type magnetic seats 32 are arranged at intervals on the top of the base plate 31 in the lateral direction, and are used to respectively adsorb the two outer panels to be assembled; the support tube 33 is located between the two switch-type magnetic seats 32, and the lateral position of the support tube 33 on the base plate 31 is adjustable; the lifting rod 34 is threadedly installed on the support tube 33, and the height of the lifting rod 34 extending from the top of the support tube 33 is adjustable; the position of the outer outer panel (i.e., the outer panel 02) is adjusted by adjusting the extended height of the lifting rod 34, so that the two outer panels can be smoothly docked.

[0032] like Figure 9 and Figure 10 As shown, when two outer panels need to be assembled, one outer panel must first be positioned and installed on the tire frame as the reference outer panel 01, and then the other outer panel must be hoisted onto the tire frame as the adjustment outer panel 02, forming a longitudinal butt joint between the reference outer panel 01 and the adjustment outer panel 02; then, multiple outer panel assembly fixing fixtures are moved into the tire frame so that each outer panel assembly fixing fixture is located below the longitudinal butt joint and is spaced apart along the extension direction of the longitudinal butt joint; then, the height of each fixing device 3 is adjusted, and the lateral angle of each bottom plate 31 is adjusted so that a switch-type magnetic seat 32 on the bottom plate 31 contacts the bottom surface of the reference outer panel 01, and the other switch-type magnetic seat 32 contacts the bottom surface of the adjustment outer panel 02 Then, turn on and adjust the switches of the two switch-type magnetic seats 32 so that they adsorb and fix the corresponding outer panels (strong adsorption is used for the reference outer panel 01 and weak adsorption is used for the adjustment outer panel 02); then, adjust the lateral position of the support cylinder 33 so that it is located below the adjustment outer panel 02, and fix the support cylinder 33 with one hand and screw the lifting rod 34 with the other hand to adjust the extension height of the lifting rod 34. Use the lifting of the lifting rod 34 to correct the position of the adjustment outer panel 02 so that the adjustment outer panel 02 and the reference outer panel 01 are smoothly docked (that is, the bottom surface of the adjustment outer panel 02 and the bottom surface of the reference outer panel 01 are smoothly transitioned); finally, adjust the adsorption force of the two switch-type magnetic seats 32 to the maximum to complete the welding of the two outer panels.

[0033] It can be understood that the height adjustment device 2 is a linear moving device such as a lifting cylinder or a hydraulic rod or a screw nut linear moving device or a gear rack linear moving device or a telescopic rod, and there is no limitation on this. Based on cost considerations, in this embodiment, the height adjustment device 2 preferably uses a telescopic rod.

[0034] Since the telescopic rod is a prior art, it is composed of a fixed cylinder 21, a movable rod 22 movably arranged in the fixed cylinder 21, and a locking device for relatively fixing the fixed cylinder 21 and the movable rod 22 extending into the fixed cylinder 21 at different depths. No further description is given here. For detailed structure, reference can be made to the telescopic rod structures in patents CN2711436Y, CN204410732U, CN210265403U, etc.; the locking device in this embodiment is preferably a locking bolt 23, which is passed through a fixing hole (not shown in the figure) on the outer wall of the fixed cylinder 21 and cooperates with fixed threaded holes (not shown in the figure) at different positions on the movable rod 22 to achieve adjustment and locking of the telescopic length of the telescopic rod.

[0035] like Figure 1 and Figure 2 As shown, the base plate 31 is fixed to the top end of the support rod 4, and the lower part of the support rod 4 is rotatably connected to the movable rod 22 of the height adjustment device 2 through an adjusting bolt 41 to adjust the lateral angle of the base plate 31; specifically, a through hole a is provided at the lower part of the support rod 4, and a threaded hole a is provided on the movable rod 22 to cooperate with the through hole a, and the adjusting bolt 41 passes through the through hole a of the support rod 4 and is threadedly engaged with the threaded hole a on the movable rod 22; when it is necessary to adjust the rotation angle of the support rod 4, it is only necessary to loosen the adjusting bolt 41 (that is, the nut of the adjusting bolt 41 is moved in the direction away from the movable rod 22), and then rotate the support rod 4 to a preset angle; then tighten the adjusting bolt 41 and use the nut of the adjusting bolt 41 and the movable rod 22 to clamp the support rod 4 to achieve locking of the angle of the support rod 4 (the support rod 4 and the movable rod 22 can also be clamped or loosened by cooperating with the adjusting bolt 41 and the adjusting nut to achieve adjustment and locking of the angle of the support rod 4).

[0036] It is understandable that when the lower portion of the support rod 4 is hinged to the movable rod 22 via a rotating shaft, a telescopic rod can be hinged to the movable rod 22 to achieve adjustment and locking of the angle of the support rod 4.

[0037] It can be understood that the adjustment and locking of the lateral position of the support cylinder 33 can be achieved through a linear moving device with a locking function such as a hydraulic push rod, an electric push rod, or by directly using the card slots 351 at different lateral positions to clamp the support cylinder 33. There is no limitation on this. In this embodiment, the card slots are preferably used to achieve the adjustment and locking of the lateral position of the support cylinder 33.

[0038] Specifically, if Figure 6 and Figure 8As shown, a fixing plate 35 is provided on the top of the base plate 31, and the fixing plate 35 is located between the two switch-type magnetic seats 32; a plurality of slots 351 that cooperate with the support tube 33 are arranged at intervals along the horizontal direction on the fixing plate 35; when the horizontal position of the support tube 33 needs to be adjusted, the support tube 33 only needs to be lifted upward to separate it from the slot 351, and then the support tube 33 can be placed in another slot 351.

[0039] like Figure 7 and Figure 8 As shown, in order to expand the extension height of the lifting rod 34, two adjacent slots 351 on the fixing plate 35 are connected by a transverse guide groove 352, and a transverse through groove 311 for the lower end of the lifting rod 34 to pass through is provided on the bottom plate 31, and the transverse guide groove 352 is for the lifting rod 34 to pass through.

[0040] Furthermore, in order to facilitate the adjustment of the extension height of the lifting rod 34, a handle 36 (such as Figure 6 shown).

[0041] Further, if Figure 1 and Figure 2 As shown, in order to move the tooling, casters 5 with brakes need to be installed at the bottom of the base 1.

[0042] Furthermore, a protective cover for protecting the switch-type magnetic base 32 is provided on the bottom plate 31 , and an opening is provided on the top of the protective cover for the magnetic surface of the switch-type magnetic base 32 to extend out.

[0043] Example

[0044] like Figure 3 、 Figure 4 、 Figure 6 As shown, this embodiment provides a fixing tool for assembling outer panels, comprising a base 1, a height adjustment device 2, a fixing device 3 and a flexible bent rod 6; wherein,

[0045] The longitudinal length of the base 1 is determined according to the longitudinal length of the outer panels to be assembled;

[0046] There are two height adjustment devices 2, and the two height adjustment devices 2 are installed on the base 1 at intervals along the longitudinal direction; the two height adjustment devices 2 are respectively connected to the two ends of the flexible curved rod 6, and are used to adjust the height and curvature of the flexible curved rod 6 (that is, to make the curvature of the flexible curved rod 6 as close as possible to the curvature of the outer panel at the longitudinal seam, and to ensure that the fixing device 3 on the flexible curved rod 6 contacts the outer panel);

[0047] There are multiple fixing devices 3, and each fixing device 3 is arranged on the flexible bent rod 6 at intervals through the support rod 4; the fixing device 3 includes a base plate 31, a support tube 33, a lifting rod 34 and two switch-type magnetic seats 32; the base plate 31 is rotatably installed on the flexible bent rod 6 through the support rod 4, and the lateral angle of the base plate 31 can be adjusted and locked; the two switch-type magnetic seats 32 are arranged at intervals along the lateral direction on the top of the base plate 31, and are used to respectively adsorb the two outer panels to be assembled; the support tube 33 is located between the two switch-type magnetic seats 32, and the lateral position of the support tube 33 on the base plate 31 is adjustable; the lifting rod 34 is threadedly installed on the support tube 33, and the height of the lifting rod 34 extending out of the top of the support tube 33 is adjustable; the position of the outer outer panel (i.e., the outer panel 02) is adjusted by adjusting the extended height of the lifting rod 34, so that the two outer panels can be smoothly docked.

[0048] like Figure 9 and Figure 10 As shown, when two outer panels need to be assembled, one outer panel must first be positioned and installed on the tire frame as the reference outer panel 01, and then the other outer panel must be hoisted onto the tire frame as the adjustment outer panel 02, forming a longitudinal joint between the reference outer panel 01 and the adjustment outer panel 02; then, the outer panel assembly fixing tool is moved into the tire frame so that each fixing device 3 is located below the longitudinal joint and is spaced apart along the extension direction of the longitudinal joint; a height adjustment device 2 is adjusted so that the curvature of the flexible bent rod 6 is close to the longitudinal curvature of the outer panel at the longitudinal joint; then the two height adjustment devices 2 are adjusted so that each fixing device 3 rises synchronously, and the lateral angle of each bottom plate 31 is adjusted so that a switch-type magnetic seat 32 on each bottom plate 31 contacts the bottom surface of the reference outer panel, The other switch-type magnetic seat 32 is in line contact with the bottom of the adjustment outer panel; then, open and adjust the switches of the two switch-type magnetic seats 32 to adsorb and fix the corresponding outer panels (strong adsorption is used for the reference outer panel 01, and weak adsorption is used for the adjustment outer panel 02); then, adjust the lateral position of the support tube 33 so that it is located below the adjustment outer panel 02, and fix the support tube 33 with one hand, and screw the lifting rod 34 with the other hand to adjust the extension height of the lifting rod 34, and use the lifting of the lifting rod 34 to correct the position of the adjustment outer panel 02 so that the adjustment outer panel 02 and the reference outer panel 01 are smoothly docked (that is, the bottom surface of the adjustment outer panel 02 and the bottom surface of the reference outer panel 01 are smoothly transitioned); finally, adjust the adsorption force of the two switch-type magnetic seats 32 to the maximum to complete the welding of the two outer panels.

[0049] It can be understood that the height adjustment device is a linear moving device such as a lifting cylinder or a hydraulic rod or a screw nut linear moving device or a gear rack linear moving device or a telescopic rod, and there is no limitation on this. Based on cost considerations, in this embodiment, the height adjustment device preferably uses a telescopic rod.

[0050] Since the telescopic rod is an existing technology, it is composed of a fixed cylinder 21, a movable rod 22 movably arranged in the fixed cylinder 21, and a locking device that relatively fixes the fixed cylinder 21 and the movable rod 22 extending into the fixed cylinder 21 at different depths (such as Figure 5 As shown in the figure), this will not be described in detail. For detailed structure, reference can be made to the telescopic rod structures in patents CN2711436Y, CN204410732U, CN210265403U, etc.; the locking device in this embodiment is preferably a locking bolt 23, which is passed through a fixing hole (not shown in the figure) on the outer wall of the fixing cylinder 21 and matched with fixed threaded holes (not shown in the figure) at different positions on the movable rod 22 to achieve adjustment and locking of the telescopic length of the telescopic rod.

[0051] like Figure 3 and Figure 4 As shown, the base plate 31 is fixed to the top end of the support rod 4, and the lower part of the support rod 4 is rotatably connected to the connecting seat 61 on the flexible bent rod 6 by an adjusting bolt 41 to adjust the lateral angle of the base plate 31; specifically, a through hole b is provided at the lower part of the support rod 4, and a threaded hole b is provided on the connecting seat 61 that cooperates with the through hole b. The adjusting bolt 41 passes through the through hole b of the support rod 4 and is threadedly engaged with the threaded hole b on the connecting seat 61; when it is necessary to adjust the rotation angle of the support rod 4, it is only necessary to loosen the adjusting bolt 41 (that is, the nut of the adjusting bolt 41 moves in the direction away from the connecting seat 61), and then rotate the support rod 4 to a preset angle; then tighten the adjusting bolt 41 and use the nut of the adjusting bolt 41 and the connecting seat 61 to clamp the support rod 4 to achieve locking of the angle of the support rod 4 (the support rod 4 and the connecting seat 61 can also be adjusted and locked by coupling the adjusting bolt 41 with the adjusting nut).

[0052] It is understandable that when the lower portion of the support rod 4 is hinged to the connecting seat 61 through the rotating shaft, a telescopic rod can be hinged on the flexible bent rod 6 to achieve adjustment and locking of the angle of the support rod 4.

[0053] It can be understood that the adjustment and locking of the lateral position of the support cylinder 33 can be achieved through a linear moving device with a locking function such as a hydraulic push rod, an electric push rod, or by directly using the card slots 351 at different lateral positions to clamp the support cylinder 33. There is no limitation on this. In this embodiment, the card slots are preferably used to achieve the adjustment and locking of the lateral position of the support cylinder 33.

[0054] Specifically, if Figure 6 and Figure 8As shown, a fixing plate 35 is provided on the top of the base plate 31, and the fixing plate 35 is located between the two switch-type magnetic seats 32; a plurality of slots 351 that cooperate with the support tube 33 are arranged at intervals along the horizontal direction on the fixing plate 35; when the horizontal position of the support tube 33 needs to be adjusted, the support tube 33 only needs to be lifted upward to separate it from the slot 351, and then the support tube 33 can be placed in another slot 351.

[0055] like Figure 7 and Figure 8 As shown, in order to expand the extension height of the lifting rod 34, two adjacent slots 351 on the fixing plate 35 are connected by a transverse guide groove 352, and a transverse through groove 311 for the lower end of the lifting rod 34 to pass through is provided on the bottom plate 31, and the transverse guide groove 352 is for the lifting rod 34 to pass through.

[0056] Furthermore, in order to facilitate the adjustment of the extension height of the lifting rod 34, a handle 36 (such as Figure 6 shown).

[0057] Further, if Figure 1 and Figure 2 As shown, in order to move the tooling, casters 5 with brakes need to be installed at the bottom of the base 1.

[0058] Furthermore, a protective cover for protecting the switch-type magnetic base 32 is provided on the bottom plate 31 , and an opening is provided on the top of the protective cover for the magnetic surface of the switch-type magnetic base 32 to extend out.

[0059] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by one of ordinary skill in the art without departing from the spirit and technical principles disclosed herein are intended to be covered by the claims of the present invention.
