Abstract
Description
Technical Field
[0001] This invention relates to the field of welding technology, and more specifically to a welding device for the inner side of a track wheel. Background Technology
[0002] The track wheel is thinner in the middle and thicker at both ends, making it difficult to forge in one go. The existing technology involves forging it in two sections first, then pressing the two sections together with an interference fit using a press fitting machine, and finally welding them together using a welding machine.
[0003] Existing welding methods are mostly manual welding. The welding process requires the use of auxiliary equipment to press the intermediate bushing onto the track wheel, and then manually weld a circle. The welding efficiency is not high, and the pressing of the bushing and the track wheel is prone to deviation, which affects the welding effect and presents problems. Summary of the Invention

Detailed Implementation
[0014] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0015] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.
[0016] For ease of explanation, spatial relative terms such as “up,” “down,” “left,” and “right” may be used herein to describe the relationship of one element or feature shown in the figure relative to another element or feature. It should be understood that, in addition to the orientation shown in the figure, spatial terms are intended to include different orientations of the device in use or operation. For example, if the device in the figure is inverted, an element described as being “down” of other elements or features would be positioned “up” of those other elements or features. Therefore, the exemplary term “down” can encompass both up and down orientations.
[0017] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0018] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, the specific implementation of the present invention will be described in detail below with reference to specific embodiments: such as Figures 1-5 The present invention is achieved through the following technical solution: a welding device for the inner side of a track wheel, including a base 13, a first mounting bracket 7 fixedly connected to the base 13, a sleeve 2 fixedly connected to the first mounting bracket 7 by bolts, an adapter 4 fixedly connected to the sleeve 2, a bracket 3 slidably connected inside the adapter 4, a threaded bolt connected to the sleeve 2, the bolt tightening and fixing the bracket 3, the position of the bracket 3 can be adjusted by loosening and tightening the bolts, a second cylinder 5 fixedly connected to the bracket 3, and a laser welding machine 6 fixedly connected to the piston rod of the second cylinder 5; A second mounting bracket 12 is fixedly connected to the base 13. A support base 9 is fixedly connected to the second mounting bracket 12. A first cylinder 1 is fixedly connected to the support base 9. The piston rod of the first cylinder 1 is rotatably connected to the pressure block 10 through the first bearing 17. The pressure block 10 is cylindrical. A limiting block 11 is fixedly connected to the pressure block 10. The limiting block 11 is circular and surrounds the pressure block 10. A section of the bottom of the pressure block 10 protrudes. The pressure block 10 is located above the tray 8. The pressure block 10 and the tray 8 are coaxial. The diameter of the pressure block 10 is smaller than the diameter of the limiting block 11. The pressure block 10 can be inserted into the bushing. The diameter of the limiting block 11 is larger than the diameter of the bushing. A rotating shaft 16 is rotatably connected to the base 13 via a second bearing 18. The top of the rotating shaft 16 is fixedly connected to a tray 8. A circular groove is provided on the tray 8, and the track wheel can be placed in the groove of the tray 8. A servo motor 15 is fixedly connected inside the base 13. A second sprocket 20 is fixedly connected to the shaft of the servo motor 15. The second sprocket 20 is connected to the first sprocket 19 through the chain 14. The first sprocket 19 is fixedly connected to the rotating shaft 16.
[0019] The working principle of this invention is as follows: the position of the welding joint of the laser welding machine 6 is adjusted by adjusting the position of the bracket 3 according to the size of the tray 8. By starting the second cylinder 5, the extension and retraction of the piston rod of the second cylinder 5 can realize the alignment of the welding joint of the laser welding machine 6 with the welding position away from the inner side of the track wheel. The track wheel is placed in the tray 8, and the bushing is inserted into the track wheel. The first cylinder 1 is started, and the pressure block 10 is inserted into the bushing. The insertion of the pressure block 10 into the bushing can prevent the bushing from deviating from the pressing of the track wheel. The limit block 11 presses down on the bushing, and the bushing is pressed onto the track wheel, thus completing the positioning. The servo motor 15 is started to drive the welded part to rotate, and the laser welding machine 6 is started to complete one revolution of welding.
