Description

Technical Field

[0001] This utility model relates to the field of positioner technology, specifically a rotating shaft mechanism for a positioner. Background Technology

[0002] A positioner is a specialized welding auxiliary device suitable for welding repositioning in rotary operations to obtain appropriate processing positions and welding speeds. Positioners can be used in conjunction with manipulators and welding machines to form automatic welding centers, or for workpiece repositioning during manual operations. Some positioners have two rotating shaft mechanisms, with a mounting frame fixed to both. During processing, the workpiece is fixed to the mounting frame, allowing it to rotate relative to the machine body to adjust the position of the mounting frame. Currently, the rotating shaft mechanisms of existing positioners are typically fixed to the machine frame first, and then the mounting frame is fixed to the rotating shaft mechanisms. However, during the assembly of the machine frame, issues such as machining accuracy may cause deviations in the installation position of the rotating shaft mechanisms, resulting in a slight misalignment of the rotation centers of the two rotating shaft mechanisms. After a period of use, this may lead to deformation of the rotating shafts, negatively impacting their usability. Utility Model Content

Detailed Implementation

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Please see Figure 1-5In this embodiment of the utility model, a rotating shaft mechanism of a positioner includes a rotating shaft module 100, and a support module 200 is provided at the bottom of the rotating shaft module 100.

[0034] The rotating shaft module 100 includes a base 110, a support 120, a rotating seat 130, a positioning seat 140, and a mounting plate 150;

[0035] The base 110 is set on the top of the support module 200. Two fixing plates 111 are fixedly connected to the top surface of the base 110. An adjusting screw 112 is screwed into the fixing plate 111. The support seat 120 is slidably connected to the inner side of the top of the base 110. The end of the adjusting screw 112 abuts against the inside of the support seat 120. The rotating seat 130 is set on the top of the support seat 120. The positioning seat 140 is set on the top of the rotating seat 130. A rotating shaft 141 is rotatably connected to the inner side of the positioning seat 140. The mounting plate 150 is fixedly connected to the end of the rotating shaft 141.

[0036] The support module 200 is fixedly mounted on the machine body 400. The top of the machine body 400 is provided with a mounting bracket 500. The machine body 400 has a drive structure and a rotating shaft. The rotating shaft is connected to the drive structure and a mounting plate is provided on the rotating shaft. The drive structure can drive the rotating shaft to rotate. The mounting bracket 500 can be fixed to the mounting plate 150 and the mounting plate by bolts, etc. After the workpiece is connected to the mounting bracket 500, the rotating shaft can be driven to rotate through the drive structure, thereby causing the mounting bracket 500 and the workpiece to rotate, and causing the rotating shaft 141 and the mounting plate 150 to rotate accordingly, thereby adjusting the angle of the workpiece.

[0037] Specifically, when assembling the body 400, the rotating shaft can be connected to the drive structure first, the support module 200 can be fixedly set on the body 400, and then the base 110 can be connected to the support module 200. After the support seat 120 is slidably set in the base 110, the support seat 120 can be slid inside the base 110 according to the position of the installed rotating shaft, and the position of the positioning seat 140 can be adjusted so that the rotating shaft 141 is as close as possible to the installed rotating shaft. Then, the adjusting screw 112 can be rotated so that the end of the adjusting screw 112 abuts against the inside of the support seat 120 to limit the support seat 120. By adjusting the horizontal position of the rotating shaft 141, the rotating shaft 141 is aligned with the installed rotating shaft as much as possible. This can avoid damage to the rotating shaft due to certain deviations in the installation, and is conducive to the normal use of the rotating shaft.

[0038] Multiple adjusting screws 112 can be installed on the fixed plate 111, and all adjusting screws 112 abut against the inside of the support base 120. The multiple adjusting screws 112 limit the support base 120, which helps to improve the fixing effect of the support base 120. When it is necessary to replace the new rotating shaft 141, the adjusting screws 112 can be rotated in the opposite direction to disengage the adjusting screws 112 from the support base 120. Then the support base 120 can be removed from the base 110 for replacement or repair of the rotating shaft 141.

[0039] Example 1

[0040] like Figure 5-6 As shown, in this embodiment, an adjusting rod 121 is rotatably connected to the inner side of the support base 120, and a connecting shaft 122 is rotatably connected to the inner side of the support base 120 and fixedly connected to the bottom surface of the rotating base 130. A worm gear 123 is fixedly sleeved on the side of the adjusting rod 121, and a worm wheel 124 that meshes with the worm gear 123 is fixedly sleeved on the side of the connecting shaft 122. The adjusting rod 121 can limit the angle of the connecting shaft 122 through the worm gear 123 and the worm wheel 124, thereby limiting the angle of the rotating base 130 in the horizontal direction. The top of the rotating base 130... Two adjusting seats 131 are fixedly connected to the surface. An adjusting rod 132 is rotatably connected to the inner side of one adjusting seat 131. A connecting shaft 133 is rotatably connected to the side of both adjusting seats 131 and is fixedly connected to the side of the positioning seat 140. A worm gear 134 is fixedly sleeved on the side of the adjusting rod 132, and a worm wheel 135 that meshes with the worm gear 134 is fixedly sleeved on the side of one connecting shaft 133. The adjusting rod 132 can limit the angle of one connecting shaft 133 through the worm gear 134 and the worm wheel 135, thereby limiting the angle of the positioning seat 140.

[0041] In specific implementation, when installing the rotating shaft 141, adjusting rod 121 and adjusting rod 132 can be rotated. Adjusting rod 121 can drive worm gear 123 to rotate, and worm gear 123 can drive worm wheel 124 to rotate, thereby causing connecting shaft 122 to rotate. Connecting shaft 122 can drive rotating seat 130 to rotate on support seat 120, adjusting the horizontal angle of rotating seat 130. Rotating seat 130 can drive positioning seat 140 and rotating shaft 141 to rotate, thereby adjusting the horizontal angle of rotating shaft 141. Adjusting rod 132 can drive worm wheel 135 to rotate through worm gear 134, thereby causing one connecting shaft 133 to rotate. One connecting shaft 133 can drive positioning seat 140 to rotate, adjusting the vertical angle of rotating shaft 141. This allows rotating shaft 141 to be aligned as much as possible with the installed rotating shaft, which is beneficial to the normal use of the rotating shaft mechanism.

[0042] like Figure 3As shown, in this embodiment, the support module 200 includes a sliding frame 210, a support frame 240, a limiting frame 220, and a fixing rod 230.

[0043] The sliding frame 210 is fixedly connected to the bottom surface of the base 110. The support frame 240 is slidably connected to the bottom side of the sliding frame 210. The bottom of the support frame 240 can be fixed to the body 400. The limiting frame 220 is fixedly connected to the inner side of the support frame 240. The top of the limiting frame 220 is rotatably connected to the positioning screw 221. The fixing rod 230 is set inside the sliding frame 210. The top of the fixing rod 230 is fixedly connected to the bottom surface of the base 110. The inside of the fixing rod 230 is screwed to the positioning screw 221. The positioning screw 221 can support the fixing rod 230, thereby supporting the base 110.

[0044] The limiting frame 220 is rotatably connected to the side of the connecting rod 222, which is rotatably connected to the inner side of the support frame 240. The limiting frame 220 can limit the position of the bottom end of the positioning screw 221 and the end of the connecting rod 222. Both the end of the connecting rod 222 and the bottom end of the positioning screw 221 are fixedly sleeved with bevel gears 223, and the two bevel gears 223 mesh and transmit power.

[0045] In practice, after adjusting the angle of the rotating shaft 141, the connecting rod 222 can be rotated. The connecting rod 222 can drive the positioning screw 221 to rotate through two bevel gears 223. When the positioning screw 221 rotates, the fixing rod 230 can move up or down along the positioning screw 221, thereby adjusting the height of the base 110, and then adjusting the height of the rotating shaft 141, so that the rotating shaft 141 is aligned with the installed rotating shaft as much as possible.

[0046] Example 2

[0047] Based on Example 1, such as Figure 4 As shown, in this embodiment, a first insertion tube 151 is slidably inserted into the side of the mounting plate 150 away from the positioning seat 140. A laser emitter can be installed inside the first insertion tube 151. A rotating ring 300 is rotatably connected to the side of the mounting plate 150. Two second insertion tubes 310 are slidably inserted into the side of the rotating ring 300 away from the positioning seat 140. A distance sensor can be installed inside the second insertion tube 310.

[0048] The axis of the plug-in sleeve 151 is on the same straight line as the axis of the rotating shaft 141, and the axis of the mounting plate 150 is on the same straight line as the axis of the rotating shaft 141. At the same time, the axis of the rotating shaft is on the same straight line as the axis of the mounting plate.

[0049] In specific implementation, during assembly, the rotating shaft can first be fixed to the drive structure, then one end of the mounting bracket 500 can be fixed to the mounting plate. The position and angle of the rotating shaft 141 can then be adjusted according to the position of the other end of the mounting bracket 500, aligning the mounting position on the mounting plate 150 with the other end of the mounting bracket 500. After adjustment, the distance between the mounting plate 150 and the mounting plate is detected by distance sensors inside the two plug-in cylinders 310. The rotating ring 300 rotates on the mounting plate 150, allowing the distance sensors to perform multi-position detection. If the distance difference detected by the two distance sensors is within a certain range, the mounting plate 150 and the mounting plate are parallel to each other, and the axes of the rotating shaft 141 and the installed rotating shaft are parallel to each other. A laser can be generated by a laser emitter, and the position of the laser's irradiation point on the mounting plate determines whether the rotating shaft 141 is aligned with the installed rotating shaft. If the irradiation point corresponds to the center of the mounting plate, then the rotating shaft 141 is aligned with the installed rotating shaft. This provides auxiliary detection of the position of the rotating shaft 141 and the installed rotating shaft, improving the alignment effect.
