[0002] Polygonal prism structure workpieces are usually workpieces such as boxes or frames. During the processing, multiple plates are usually connected in sequence, and then the intersection of two adjacent plates is welded to form a polygonal prism structure workpiece; or the entire plate is bent multiple times, and then the ends are aligned and welded to form a polygonal prism structure workpiece.
[0003] In the process of processing polygonal workpieces, most of the time, the plates are manually aligned and spliced before welding. There is also a method of pre-clamping and fixing the workpiece with welding fixtures. In the process of clamping and positioning the workpiece with a mechanical welding fixture, one fixture cannot adapt to the clamping and positioning of workpieces of various sizes, which easily blocks the docking position between the two plates and makes welding inconvenient. Therefore, there is an urgent need to improve the welding fixture so that the gaps that need to be welded will not be blocked during the welding processing of polygonal workpieces, and the welding fixture can be adapted to clamp and position workpieces of different sizes.

It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0026] It should be noted that in the embodiments of the present utility model, all directional indications (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.
[0027] In addition, the descriptions of “first”, “second”, etc. in the embodiments of the present invention are only used for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features.
[0028] The embodiment of the utility model provides a welding tool for welding multi-prism workpieces, which can clamp and fix the workpiece to be welded, and can also adapt to workpieces of different sizes. During the clamping and fixing process, the butt joint between two adjacent plates can be avoided, thereby facilitating the welding of the butt joint between the two plates.
[0029] like Figure 1-4As shown, an embodiment of the utility model provides a multi-prism structure workpiece welding tool, including a rotary positioner 100, on which a clamping device 200 is fixedly arranged, wherein the clamping device 200 includes a base plate 201, a limiting component 210 and a pushing component 220. When the workpiece to be welded needs to be clamped and fixed, the workpiece to be welded is placed on the base plate 201, and the pushing component 220 pushes the workpiece to be welded toward the limiting component 210, so that the workpiece to be welded is positioned under the mutual cooperation of the limiting component 210 and the pushing component 220. The bottom plate 201 is fixedly mounted on the rotary positioner 100 and driven to rotate by the positioner 100. When the positioner 100 rotates, the direction of the workpiece to be welded can be changed, so as to facilitate welding of multiple butt joints of the workpiece to be welded; the limiting assembly 210 includes two limiting plates 211, the two limiting plates 211 are vertically arranged, and the extension lines of the sides of the two limiting plates 211 intersect with each other and form an angle that matches the prism edge line. The two limiting plates 211 are connected to the bottom plate 201 by sliding along a straight line in the direction of the angle; the pushing assembly 22 The limiting assembly 210 is arranged on the bottom plate 201, and includes a push member 221 and a push driving device 222 which is transmission-connected with the push member 221 and drives the push member 221 to reciprocate toward the limiting assembly 210. The push member 221 includes two push arms 223, and an angle adapted to the prism edge line is defined between the two push arms 223. In this embodiment, the push driving device 222 is a cylinder, and the piston rod of the cylinder is connected to the push member 221, so as to drive the push member 221.
[0030] In the process of clamping and fixing the workpiece to be welded, the workpiece to be welded is placed on the bottom plate 201, and the push plate moves toward the workpiece to be welded under the drive of the push drive device 222, and the workpiece to be welded is clamped on the bottom plate 201 under the restriction of the limit plate 211, thereby completing the fixing work. In the clamping process, the limit plate 211 is slid along a straight line to adjust the distance between the two limit plates 211, thereby changing the angle formed between the two limit plates 211 that matches the prism edge line, so that it can adapt to the clamping and positioning work of multi-prism workpieces of different sizes, and can make the butt joint of the workpiece to be welded leak at the angle position between the two limit plates 211, so as to facilitate welding.
[0031] In this embodiment, if Figure 4As shown, the two pushing arms 223 each include a buffer structure 230. In the process of pushing the workpiece to be welded toward the limit plate 211, the workpiece to be welded is prevented from being damaged due to excessive pushing force. The buffer structure 230 includes a buffer plate 231, a sliding rod 232 and a first elastic member 233. The buffer plate 231 is located on the inner side of the pushing arm 223 and is arranged parallel to the pushing arm 223. That is to say, the two ends of the buffer plate 231 correspond to the two pushing arms 223 respectively and form an angle that matches the edge line. One end of the sliding rod 232 is fixedly connected to the buffer plate 231, and the other end is slidably connected to the pushing arm 223. The first elastic member 233 is mounted on the sliding rod 232 and provides an elastic force toward the inner side for the buffer plate 231, so that the buffer plate 231 is away from the surface of the pushing arm 223 under the push of the elastic force. In this embodiment, the two buffer plates 231 are an integrated structure, and the two buffer plates 231 define an angle that is the same as the two pushing arms 223.
[0032] Since the pushing drive device 222 is composed of a cylinder, the thrust generated by the pushing of the pushing member 221 toward the workpiece to be welded is fixed and inconvenient to adjust. Therefore, it is easy for the workpiece to be welded to be impacted or pressed due to the large pushing force, thereby causing damage to the workpiece to be welded. At this time, in the process of pushing the workpiece to be welded toward the limit plate 211, the pushing force on the workpiece to be welded is elastically absorbed by the buffer structure 230, thereby reducing the impact of the excessive pushing force on the workpiece to be welded, and avoiding the situation where the workpiece to be welded is pressed and deformed.
[0033] In this embodiment, the bottom plate 201 is provided with slide grooves 202 in which two limit plates 211 are slidably connected, and the bottom plate 201 is provided with a sliding drive device 212 which is transmission-connected with the limit plates 211 to drive the limit plates 211 to slide in a straight line direction in the slide grooves 202, so that the two limit plates 211 are close to or away from each other. In this embodiment, a dovetail-shaped sliding portion 2111 is provided under the limit plates 211, and correspondingly, the slide groove 202 is also provided with a dovetail structure, so as to ensure the stability of the limit plates 211 sliding in the slide grooves 202.
[0034] In this embodiment, if Figure 1-3 As shown, the sliding drive device 212 includes a base 2121 and a push rod 2122, wherein the base 2121 is fixed on the bottom plate 201 corresponding to the limit plate 211; the push rod 2122 is threadedly connected to the base 2121, and the axial direction of the push rod 2122 is the same as the direction of the slide groove 202, and one end of the push rod 2122 abuts against the side of the limit plate 211, and the other end constitutes a rotating end for rotation.
[0035] During the process of moving the limit plate 211, the pushing rod 2122 is screwed in toward the limit plate 211 by rotating the rotating end of the pushing rod 2122, thereby moving the limit plate 211. The threaded connection enables the pushing rod 2122 to move in a straight line with higher precision and more stable push on the limit plate 211.
[0036] At the same time, a second elastic member 2123 is also disposed in the slide groove 202, and the second elastic member 2123 provides elastic force for the limit plate 211 toward the sliding drive device 212. The second elastic member 2123 can make the limit plate 211 receive the directional elastic force of the second elastic member 2123 during the process of pushing the limit plate 211, thereby further increasing the stability during the process of moving the limit plate 211, and during the process of the push rod 2122 withdrawing, the limit plate 211 can automatically move in the direction away from the other limit plate 211 along with the push rod 2122 under the elastic force of the second elastic member 2123.
[0037] In a polyhedral structure welding tool provided in this embodiment, the polyhedral workpiece can be clamped and fixed. During the clamping process, the position between the limit plates 211 and the position of the angle between the two limit plates 211 can be adjusted to adapt to the clamping and fixing of workpieces to be welded of different sizes. In addition, by changing the position of the angle between the two limit plates 211, the butt joints between the plates can be avoided during the clamping and fixing of the polyhedral workpiece, so as to avoid blocking the butt joints and affecting the welding.
[0038] For those skilled in the art, various other corresponding changes and deformations can be obtained according to the structure and principle disclosed by the utility model, and all of these changes and deformations belong to the protection scope of the utility model.
