Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, and in particular to a truss welding fixture platform. Background Technology

[0002] Trusses are commonly used assemblies in stage construction and scaffolding erection, and are in high demand in the market. A truss consists of uprights for main support and side supports connecting adjacent uprights. During truss production, the connection between uprights and side supports is typically achieved through welding. However, current truss welding techniques have significant shortcomings. Firstly, welding efficiency is low. Secondly, due to the three-dimensional structure of trusses, positioning the uprights and side supports (which include straight and diagonal side supports along the length of the uprights) is difficult, especially when multiple side supports need to be arranged sequentially along the length of the uprights, further reducing welding efficiency.

[0003] To address the positioning problem of side support rods, some companies have developed side support rod positioning molds. For example, the truss spot welding mold with patent publication number 209578622U discloses a lifting and positioning component that includes a lifting plate, on which positioning stations are set. The positioning stations include several straight and inclined tube slots spaced along the length of the lifting plate, as well as support tube slots located on both sides of the lifting plate's width. In actual operation, when welding truss workpieces, a lifting cylinder lifts the lifting plate, along with its straight, inclined, and support tube slots, to a suitable height, positioning one side of the truss workpiece within these slots. Because the side support rods and inclined rods of the truss workpiece extend into corresponding straight and inclined tube slots at both ends, welding operations can be completed efficiently and quickly using a welding machine.

[0004] However, judging from the accompanying drawings in the patent specification and actual usage, two or more lifting cylinders are typically used to control the lifting of the platform to enhance its support effect. However, practical operation shows that the cylinders are not very stable, especially when multiple cylinders are used simultaneously, which easily leads to asynchrony and causes the lifting platform to deviate to the side, negatively impacting the welding effect of the side supports on the uprights. Therefore, it is necessary to develop a new type of truss welding fixture platform to overcome the aforementioned shortcomings of the existing technology. Utility Model Content

[0005] This invention overcomes the shortcomings of the prior art and provides a truss welding fixture platform. By using a servo motor to control the lifting, it has the advantages of high precision and good stability, which helps to enhance the stability of welding and improve the welding quality.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] A truss welding fixture platform includes a frame with several positioning molds for fixing side support rods. Two sets of slide blocks are slidably mounted on the frame, allowing the distance between the two sets of slide blocks to be adjustable. The sliding direction of the slide blocks is the same as the arrangement direction of the positioning molds. Each slide block includes a base with clamping components that are vertically adjustable. When the two sets of slide blocks approach each other, the corresponding clamping components work together to clamp the two ends of the uprights of the truss workpiece. Longitudinal guide rails are provided on both sides of the slide blocks, and the two ends of the clamping components are slidably connected to the longitudinal guide rails. A lead screw nut is provided on the clamping component, which is connected to a lead screw, and the lead screw is connected to a servo motor fixed on the slide block.

[0008] Furthermore, the clamping component includes a rotating shaft, a template positioning plate connected to the rotating shaft, a template connected to the template positioning plate, and a fixing rod provided on the template for inserting and fixing the upright.

[0009] Furthermore, the clamping component is equipped with a locking cylinder, the piston rod of the locking cylinder is connected to the movable plate, the movable plate is connected to the locking rod, and the locking rod slides laterally through the clamping component to one side of the template positioning plate. The template positioning plate is correspondingly provided with a socket for the locking rod to be inserted.

[0010] Furthermore, the locking cylinder and the rotating shaft are located on the same axis, and they are located on opposite sides of the clamping component; there are two locking rods, which are symmetrically arranged with respect to the locking cylinder.

[0011] Furthermore, the angle between adjacent sockets is 90°.

[0012] Furthermore, the positioning mold has grooves for the side support rods to be placed in different directions.

[0013] Furthermore, one or two sets of the slides are provided with adjustable pitch drive motors, which are connected to reducers, and the reducers are connected to gears; a rack extends from the frame, and the gears are connected to the rack.

[0014] Furthermore, the frame is provided with a transverse guide rail, the extension direction of which is consistent with the extension direction of the rack; a slider is provided at the lower end of the slide block, and the slider is slidably connected to the transverse guide rail.

[0015] Furthermore, the frame is provided with a T-shaped assembly slot, and the lower end of the positioning mold is connected to a T-shaped guide rod, which is slidably assembled in the T-shaped assembly slot.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] In this invention, the positioning mold is fixed to the frame, and the clamping components of the two sets of slides are precisely controlled by a servo motor for lifting. During operation, the side support rod to be welded is placed on the positioning mold, and then the clamping components of the two sets of slides clamp the upright rod and lower it to the side support rod position to complete the welding operation. Compared with the traditional cylinder-driven lifting scheme, the advantage of servo motor drive lies in its higher positioning accuracy and stability, thereby improving the accuracy and consistency of component positioning during the welding process, ultimately contributing to improved welding quality.

[0029] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0030] like Figures 1 to 8 As shown, this utility model claims protection for a truss welding fixture platform, including a frame 1. The frame 1 is equipped with several positioning molds 2 for fixing side support rods. The difference from traditional equipment is that in this design, the positioning molds 2 are mounted stationary on the frame 1, and the side support rods are directly placed on the positioning molds 2 for welding to the uprights. The positioning molds 2 have rod grooves 201 for arranging the side support rods in different directions, which helps in positioning the side support rods. The frame 1 is provided with a T-shaped assembly groove 101, and the lower end of the positioning mold 2 is connected to a T-shaped guide rod 202. The T-shaped guide rod 202 slides within the T-shaped assembly groove 101, which helps the positioning mold 2 to be installed along the T-shaped assembly groove 101. The matching and corresponding installation of the T-shaped guide rod 202 and the T-shaped assembly groove 101 helps the several positioning molds 2 to be installed in a straight line, reducing the likelihood of lateral deviation and facilitating the accurate subsequent welding of the side support rods to the uprights.

[0031] Two sets of slide blocks 3 are slidably mounted on the frame 1, allowing the distance between the two sets of slide blocks 3 to be adjustable. The sliding direction of the slide blocks 3 is the same as the arrangement direction of the positioning molds 2. One or both sets of slide blocks 3 are equipped with an adjustable-pitch drive motor 8, which is connected to a reducer 9, and the reducer 9 is connected to a gear 10. A rack 11 extends from the frame 1, and the gear 10 is connected to the rack 11. Therefore, the adjustable-pitch drive motor 8 and the reducer 9 drive the gear 10 to rotate, which interacts with the rack 11, thereby enabling the slide block 3 to move. A transverse guide rail 12 is provided on the frame 1, and the extension direction of the transverse guide rail 12 is consistent with the extension direction of the rack 11. A slider 13 is provided at the lower end of the slide block 3, and the slider 13 is slidably connected to the transverse guide rail 12. The cooperative movement of the slider 13 and the transverse guide rail 12 contributes to the smooth movement of the slide block 3.

[0032] The slide block 3 includes a base 301, on which clamping components 4 are vertically and flexibly mounted. When two sets of slide blocks 3 approach each other, the corresponding clamping components 4 work together to clamp the two ends of the uprights of the truss workpiece. Longitudinal guide rails 302 are provided on both sides of the slide block 3, and the two ends of the clamping components 4 are slidably connected to the longitudinal guide rails 302. A lead screw nut 401 is provided on the clamping component 4, which is connected to the lead screw 402. The lead screw 402 is connected to a servo motor 403 fixed on the slide block 3. Therefore, since the longitudinal guide rails 302 slide and limit the two sides of the clamping component 4, when the servo motor 403 drives the lead screw 402 to rotate, it interacts with the lead screw nut 401, thereby controlling the lifting and lowering of the clamping component 4.

[0033] The clamping component 4 includes a rotating shaft 404, which is rotatably connected to the clamping component 4 via a bearing. A template positioning plate 405 is connected to the rotating shaft 404, and a template 406 is connected to the template positioning plate 405. A fixing rod 4061 for inserting and fixing the upright is provided on the template 406.

[0034] The clamping component is equipped with a locking cylinder 5. The piston rod of the locking cylinder 5 is connected to the movable plate 6, and the movable plate 6 is connected to the locking rod 7. The locking rod 7 slides laterally through the clamping component and extends to one side of the template positioning plate 405. The template positioning plate 405 is provided with a corresponding insertion hole 4051 for the locking rod 7 to be inserted. The locking cylinder 5 drives the movable plate 6 to move, causing the locking rod 7 to be inserted into or withdrawn from the insertion hole 4051, thereby placing the template positioning plate 405 in a locked state or a free-rotating state.

[0035] The locking cylinder 5 and the rotating shaft 404 are located on the same axis, and they are respectively located on both sides of the clamping component, thus ensuring good structural correspondence. There are two locking rods 7, which are symmetrically arranged with the locking cylinder 5, thus providing good stability for the template positioning plate 405. The angle between adjacent insertion holes 4051 is 90°, which allows the template positioning plate 405 to be fixed every 90° of rotation.

[0036] The working principle of this truss welding fixture platform is as follows: Before operation, the servo motors 403 on the two slide blocks 3 are controlled to raise the clamping components 4 on the two slide blocks 3 to the same height. Then, the side crossbars to be welded and fixed are placed in the rod grooves 201 of the positioning mold 2. Next, the uprights (all of which are hollow) are taken out, and one end of the upright is inserted into the fixing rod 4061 of the template 406 on one of the slide blocks 3 (there are four fixing rods 4061, so four uprights are inserted; this can be set so that the four uprights form the truss workpiece). Then, the other slide block 3 is controlled to move closer, so that the fixing rod 4061 of the template 406 on the slide block 3 that has moved closer is inserted into the other end of the upright. Finally, the servo motors 403 on the two slide blocks 3 are controlled to lower the uprights to the side crossbars, and then welding is performed. In this design, because servo motors are used for control, it has the advantages of high precision and good stability. After one side of the truss workpiece is welded, the clamping component 4 is raised by the servo motor 403, and the side crossbar is placed in the rod groove 201 of the positioning mold 2 and welded to the next side of the truss workpiece.

[0037] Since the rotating shaft 404, template positioning plate 405, and template 406 are rotatably mounted on the clamping component 4, after welding one side of the truss workpiece, it can be rotated to the next side for welding. During welding, the locking cylinder 5 controls the locking rod 7 to be inserted into the insertion hole 4051, so that the template positioning plate 405 is fixed in a locked state, that is, it will not rotate on its own before welding. When the truss workpiece needs to be rotated after welding one side, the locking cylinder 5 controls the locking rod 7 to be pulled out of the insertion hole 4051, so that the template positioning plate 405 returns to a free rotation state before rotation. Thus, the above structural design helps to enhance the stability of welding and improve the welding quality.

[0038] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. However, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
