DETAILED DESCRIPTION

[0023] The following will be combined with the drawings of the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] In order to solve the problem of assembling parts of a long and heavy cylindrical / conical shell, this embodiment provides a rotary tool for assembling parts of a cylindrical or conical shell. Figure 1 As shown, the rotary tooling includes a chassis 1 placed on the ground, and the chassis 1 is equipped with a workbench upper seat 3, which is connected to the chassis 1 through a toothless slewing bearing 2. The bearing force of the workbench upper seat 3 can be transmitted to the chassis 1, and the workbench upper seat 3 can rotate relative to the chassis 1 through the toothless slewing bearing 2; a group of guide rail assemblies 4 and a ball screw assembly 5 located between a group of guide rail assemblies 4 are installed on the workbench upper seat 3; a group of support seats are slidably installed on the guide rail assembly 4, and the spacing between a group of support seats is adjusted by the ball screw assembly 5; a group of support seats includes a main seat 6 and an auxiliary seat 7, and the main seat 6 and the auxiliary seat 7 are both provided with a group of rubber-coated roller assemblies 8 that can roll in contact with the outer wall of the cylindrical or conical shell, and the rubber-coated roller assembly 8 on the auxiliary seat 7 can be raised and lowered, so as to be compatible with the outer wall of the cylindrical or conical shell with steps.

[0025] When assembling parts of a longer and heavier cylindrical / conical shell, the cylindrical / conical shell can be placed horizontally on the rubber-coated roller assembly 8 of the main pedestal 6 and the auxiliary pedestal 7; the cylindrical / conical shell can be rotated 360° relative to the ground by rotating the workbench upper seat 3 relative to the chassis 1; at the same time, the rubber-coated roller assembly 8 can be used to rotate the cylindrical / conical shell 360° relative to the workbench upper seat.

[0026] In this embodiment, the rotation of the workbench seat 3 relative to the chassis 1 is achieved in the following manner:

[0027] like Figure 1 and Figure 2 As shown, the chassis 1 in this embodiment is a circular plate structure; the workbench upper seat 3 has a cylindrical structure at the bottom and a rectangular plate structure at the top; the chassis 1 and the workbench are both made of rigid metal materials. The toothless slewing bearing 2 is a commercially available finished device. The chassis 1, the toothless slewing bearing 2, and the workbench upper seat 3 are vertically coaxial. A groove is formed at the center of the chassis 1 to fit the inner ring of the toothless slewing bearing 2. The groove is provided with a circle of through holes for bolts to pass through. The chassis 1 is fixedly connected to the inner ring of the toothless slewing bearing 2 by a number of bolts. A flange is formed below the bottom cylindrical structure of the workbench upper seat 3. The flange is provided with a circle of through holes for bolts to pass through. The bottom cylindrical structure of the workbench upper seat 3 is fixedly connected to the outer ring of the toothless slewing bearing 2 by a number of bolts. According to the above installation method, the workbench upper seat 3 can rotate 360° relative to the chassis through the toothless slewing bearing 2.

[0028] Furthermore, as a preferred technical solution of this embodiment, in order to position and brake the rotation, as Figure 2As shown, a positioning assembly and a brake assembly 9 are provided between the workbench upper seat 3 and the chassis 1. The brake assembly 9 is mounted on the chassis 1 and is capable of abutting against the outer ring of the toothless slewing bearing 2. The brake assembly 9 belongs to the prior art, and its structure is disclosed in the patent document with application number 202323527123.4, so it will not be described in detail here. The positioning assembly includes a positioning rod 10 passing through the workbench upper seat 3 and the outer ring of the toothless slewing bearing 2. A return spring 11 is mounted on the positioning rod 10. One side of the return spring 11 abuts against the bottom surface of the outer ring of the toothless slewing bearing 2, and the other side abuts against the spherical body at the end of the positioning rod 10. A positioning hole 12 is provided on the chassis 1 to cooperate with the positioning rod 10.

[0029] When the workbench base 3 is rotated to a certain angle relative to the chassis 1, the lower end of the positioning rod 10 is inserted into the positioning hole 12 on the chassis 1 under the action of the spring, forming a limit. When the workbench base 3 needs to be rotated again, the positioning rod 10 needs to be pulled upward to disengage the bottom of the positioning hole 12. During the rotation of the workbench base 3, the assembler can also use his foot to step on the brake assembly 9 to brake.

[0030] In this embodiment, the spacing adjustment of a set of support bases is achieved by the following method:

[0031] like Figure 1 and Figure 3 As shown, a set of guide rail assemblies 4 are installed on the front and rear sides of the workbench base 3; the guide rail assembly 4 includes a slide rail 13 installed on the workbench base 3, and a slider 14 slidably installed on the slide rail 13; the slide rail 13 and the slider 14 can be commercially available finished equipment, such as: a linear guide pair.

[0032] like Figure 1 and Figure 3 As shown, the ball screw assembly 5 includes a lead screw 16, a lead screw support 15, a handwheel 17, and a nut support 18. The two lead screw support 15 are fixedly mounted on the left and right sides of the workbench upper base 3. The ends of the lead screw 16 are rotatably mounted on the workbench upper base 3 through the lead screw support 15. One end of the lead screw 16 passes through the lead screw support 15 and is mounted with the handwheel 17. The lead screw 16 is provided with a bidirectional thread, and two nut supports 18 are mounted through the bidirectional thread. The nut supports 18 are fixedly connected to the center of the bottom of the support base, and the two sides are fixedly connected to the slider 14.

[0033] When the handwheel 17 is turned, since the screw 16 adopts a bidirectional thread design, the main support seat 6 and the auxiliary support seat 7 slide away from each other or towards each other on a set of guide rail assemblies 4, thereby satisfying the spacing adjustment of a set of support seats to adapt to cylindrical / conical shells of different length ranges.

[0034] Furthermore, as a preferred technical solution of this embodiment, in order to avoid the hand wheel 17 from causing the spacing adjustment of a group of support bases to change, as shown in FIG. Figure 3 As shown, in this embodiment, a guide rail brake 19 is installed on the slider 14 at the bottom of the main base 6. The guide rail brake 19 includes a brake frame 20 installed on both sides of the slider 14, and a brake bolt 21 threadedly installed on the brake frame 20. After the spacing adjustment of a group of support bases is completed, the brake bolt 21 can be rotated to pass through the brake frame 20 and abut against the slide rail 13 to form a limit.

[0035] In addition, as a preferred technical solution of this embodiment, in order to facilitate the operator to quickly understand the approximate length of the cylindrical / conical shell, such as Figure 1 and Figure 3 As shown, in this embodiment, a pointer 36 is installed on the side of the main base 6, and a steel ruler 37 is installed on the side of the workbench upper base 3, so as to determine the opening and closing distance between the main base and the auxiliary base.

[0036] The structure of the support base and rubberized roller assembly 8 in this embodiment is as follows:

[0037] like Figure 1 and Figure 4 As shown, in a set of support bases, the one close to the hand wheel 17 is the main base 6, and the one away from the hand wheel 17 is the auxiliary base 7; the main base 6 and the auxiliary base 7 have similar structures, both including a base plate 22 fixedly connected to the nut seat 18 and the slider 14, and a boss 23 provided on the base plate 22. The difference is that the boss 23 on the main base 6 is fixedly mounted on the base plate 22, while the boss 23 on the auxiliary base 7 is mounted on the base plate 22 in a vertically movable manner through a set of guide frames 24. Figure 5 As shown, a lifting screw 25 is provided on the auxiliary base 7, and a threaded tube that cooperates with the lifting screw 25 is provided on the auxiliary base 7. The lifting screw 25 passes through the boss 23 on the auxiliary base 7, and an annular body is formed at the bottom of the boss 23; when the lifting screw 25 is rotated, since the lifting screw 25 is threadedly connected to the threaded tube, it drives the boss 23 to move vertically between a group of guide frames 24 through the annular body.

[0038] like Figure 1 、 Figure 4 and Figure 5 As shown, the rubberized roller assembly 8 includes a group of rubberized rollers 26 symmetrically arranged on the boss 23. A group of rubberized rollers 26 are rotatably mounted on the bosses 23 of the main base 6 and the auxiliary base 7 through a small shaft 27. A certain distance is left between the group of rubberized rollers 26 to meet the requirements of a cylindrical / conical shell with a certain diameter range.

[0039] When the shell is a longer and heavier cylindrical shell, the main base 6 and the auxiliary base 7 can be adjusted to the same horizontal height; then the longer and heavier cylindrical shell is placed horizontally on the rubberized roller assembly 8 of the main base 6 and the auxiliary base 7, and the rubberized roller assembly 8 is used to rotate the cylindrical / conical shell 360° relative to the workbench upper base.

[0040] When the shell is a longer and heavier conical shell, the height of the auxiliary base 7 can be raised so that the auxiliary base 7 supports the cone end of the longer and heavier conical shell, so that the longer and heavier conical shell is still placed in a horizontal posture on the rubberized roller assembly 8 of the main base 6 and the auxiliary base 7. The rubberized roller assembly 8 is used to rotate the cylindrical / conical shell 360° relative to the workbench upper base.

[0041] When a long and heavy cylindrical / conical shell is rotated to a certain angle and needs to be positioned, such as Figure 1 、 Figure 4 and Figure 5 As shown, a movable wedge 29 is installed in the middle of the boss 23 through a screw 28. The screw 28 passes through one end of the wedge 29 and is threadedly connected to the boss 23. When positioning is required, the screw 28 is rotated to make the wedge 29 abut against the rubber drum 26, thereby braking the rotation of the rubber drum 26.

[0042] Furthermore, as a preferred technical solution of this embodiment, when the housing needs to be assembled at a certain angle for a long time, in order to prevent the housing from falling, Figure 1 As shown, in this embodiment, hanging rings 30 are provided on both sides of the base plates 22 of the main stand 6 and the auxiliary stand 7, and fixing belts 31 are detachably installed through the hanging rings 30; the fixing belts 31 are used to further tighten and fix the shell.

[0043] In addition, as a preferred technical solution of this embodiment, in order to assist in axial positioning of the cylindrical / conical shell, this embodiment also provides a set of auxiliary support components. Figure 1 and Figure 6 As shown, slots 32 are formed on both sides of the workbench base 3 below the guide rail assembly 4. The auxiliary support assembly is slidably mounted in the slots 32. The auxiliary support assembly is positioned by bolts passing through and threadedly connected to the slots 32. The auxiliary support assembly includes an L-frame 33 slidably mounted in the slots 32, and a bracket 34 mounted on the L-frame 33. A bracket block 35 is mounted on the bracket 34.

[0044] When the shell is a cylindrical shell, the support blocks 35 on both sides can be omitted. By adjusting the position of the bracket 34, the inner side surface of the bracket 34 can be in contact with the end surface of the cylindrical shell, thereby playing an axial positioning role for the cylindrical shell; when the shell is a conical shell, the support block 35 on one side of the cone end can be installed according to the posture of the conical shell, so that the cone end of the conical shell is in contact with the top of the support block 35, and the other end surface of the conical shell is in contact with the inner side surface of the bracket 34, thereby playing a supporting and positioning role for the conical shell.

[0045] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
