[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Before welding the shaft roller, in order to prevent the shaft roller from shifting during the welding process, it is usually necessary to fix it. In the prior art, the two sides of the shaft roller are mostly fixed by two fixing clamps. When fixing shaft rollers of different specifications, the specifications of the fixing clamps usually need to be replaced accordingly, which is time-consuming and labor-intensive and has low applicability. The following describes a rotating tool for shaft roller welding provided by some embodiments of the utility model in conjunction with the accompanying drawings.

[0023] Embodiment 1:

[0024] In order to solve the problem that the fixing splint needs to be replaced when fixing rollers of different specifications, Figure 1 , Figure 2 and Figure 3As shown, a rotary tooling for shaft-roller welding is proposed, including a supporting mechanism 1, through which the whole device is connected and supported, two fixing mechanisms 2 are arranged on the supporting mechanism 1, and the fixing mechanisms 2 are used to fix shaft rollers of different specifications, which saves time and labor and is convenient for workers to perform welding, and the bottoms of the two fixing mechanisms 2 are each provided with an adjusting mechanism 3, and the adjusting mechanism 3 is used to accurately adjust the welding angle, so that the welding position between the welded parts 201 can be accurately adjusted to reduce the error.

[0025] In order to make the device convenient for welding and fixing shaft rollers of different specifications, a fixing mechanism 2 is proposed, which is provided by installing two circular plates 202, an electric telescopic rod 203 is installed between the two circular plates 202, two micro brackets 206 are fixedly connected to the opposite sides of the two circular plates 202, a connecting shaft 205 is fixedly connected between the two micro brackets 206 located on the same circular plate 202, two fixing plates 204 are rotatably connected to the two connecting shafts 205, a welding piece 201 is installed between the plurality of fixing plates 204, a limiting rod 208 is fixedly connected to the side of the plurality of fixing plates 204 away from the welding piece 201, two adjusting plates 207 are slidably connected to the opposite sides of the two circular plates 202, and the plurality of adjusting plates 207 are respectively slidably connected to the plurality of limiting rods 208, two circular plates 202 are fixedly connected to one another on one side, and two connecting blocks are located between the two connecting blocks on the same circular plate 202. A bidirectional threaded rod a209 is rotatably connected, and a motor for driving the bidirectional threaded rod a209 to rotate is installed on one side of a connecting block located on different circular plates 202. The two bidirectional threaded rods a209 are driven to rotate by the two motors. Since the two sections of threads on the two bidirectional threaded rods a209 are respectively threadedly connected to the two adjustment plates 207 close to them, under the action of multiple limit rods 208, the distance between the two adjustment plates 207 sliding on the same circular plate 202 can be easily adjusted, thereby changing the angle between the two fixed plates 204. By controlling the electric telescopic rod 203, the distance between the two groups of different adjustment plates 207 can be easily adjusted. Therefore, through the coordinated adjustment of the angle and the distance, the multiple fixed plates 204 can clamp and fix the shaft roller weldments 201 of different specifications, thereby ensuring the stability of the weldment 201 during the welding process and greatly improving the applicability of the device.

[0026] Embodiment 2:

[0027] On the basis of Example 1, the technical solution proposed in Example 1 is used to solve the problem that most of the existing technologies use two fixing clamps to fix the two sides of the shaft roller. When fixing shaft rollers of different specifications, it is usually necessary to change the specifications of the fixing clamps accordingly, which is time-consuming and labor-intensive and has low applicability. However, when welding between different welding parts 201, it is usually necessary to rotate and adjust the welding angle as required. In the existing technology, most staff visually estimate the rotation angle based on experience. The error of this adjustment method is large, which affects the welding effect.

[0028] In order to improve the accuracy of the device in adjusting the welding angle, Figure 1 and Figure 2 as well as Figure 4 As shown, an adjustment mechanism 3 is proposed, which includes two fixed blocks 301 sliding in two through holes 102 respectively, the tops of the two fixed blocks 301 are fixedly connected with circular bottom plates 302, two circular plates 202 close to the workbench 101 are provided with through grooves 303, and clamping blocks 304 are slidably connected in the two through grooves 303, a plurality of limit blocks 305 are fixedly connected to the two circular bottom plates 302, and a plurality of limit blocks 305 are provided with fitting holes 306, and arc rods 308 are fixedly connected to the two clamping blocks 304, and magnetic suction plates 307 are installed on the top walls of the two through grooves 303, and metal plates are installed on the tops of the two clamping blocks 304, and a plurality of fitting holes 306 can be clamped with the clamping blocks 304, and the two circular plates 202 close to the two circular bottom plates 302 are rotatably connected thereto. By pulling the arc rod 308, the block 304 slides in the through groove 303, so that the magnetic plate 307 is attracted and connected with the metal plate. At this time, the circular plate 202 is rotated to rotate and adjust the angle of the welding part 201. When the angle is selected, the arc rod 308 is pressed to make the block 304 engage with the fitting hole 306 on the limit block 305, so as to fix the circular plate 202. The servo motor controls the rotation of the bidirectional threaded rod b to make the two welding parts 201 close to each other, which is convenient for the staff to weld the welding points and ensure the welding effect of the device. At the same time, multiple limit blocks 305 are distributed in a circular array, and the angles between their center lines are 15°, so they can play the role of an angle disk, which greatly improves the accuracy of the rotation adjustment of the welding angle between the welding parts 201.

[0029] In order to enable the device to weld stably, a supporting mechanism 1 is proposed. A workbench 101 is installed, and two through holes 102 are symmetrically provided on the workbench 101. A plurality of supporting columns are fixedly connected to the bottom of the workbench 101. The two through holes 102 enable the two fixed blocks 301 to slide internally. Two support plates are fixedly connected to the bottom of the workbench 101. A bidirectional threaded rod b is installed between the two support plates. The two fixed blocks 301 are respectively threadedly connected to the two sections of the thread of the bidirectional threaded rod b. A servo motor for driving the bidirectional threaded rod b is installed on one side of the support plate. The servo motor drives the bidirectional threaded rod b to rotate so that the two fixed blocks 301 drive the distance between the two circular bottom plates 302 to change, so that the welding positions of the two welding parts 201 are in contact, thereby ensuring the welding effect of the device.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
