Description

Technical Field

[0001] The utility model relates to the field of tooling platforms for special workpiece welding, in particular to a cross-belt straight-rail welding tooling. Background Art

[0002] Cross-belt straight rails usually refer to a guide rail system used in mechanical devices, which combines the characteristics of cross rollers and linear guides to adapt to different movement needs. Under current technical conditions, the welding process of cross-belt straight rails is usually completed by operators manually using small welding fixtures. Due to the large size of cross-belt straight rails, at least multiple people are required to cooperate with each other, and the inevitable shaking and shaking during the operation can easily lead to reduced quality of the welded workpiece. Therefore, in order to improve the efficiency of cross-belt straight rail welding, it is necessary to use a cross-belt straight rail welding fixture to improve the welding processing quality of the workpiece. At present, there are also some clamping and positioning tooling platforms specially used for cross-belt straight rails on the market, such as a cross-belt straight rail welding fixture disclosed in the Chinese utility model patent application document with application number CN201820912467.7, which includes a rail bracket, an outer ring straight rail, an inner ring straight rail, a clamping device and a crossbeam, wherein outer ring straight rails are installed on both sides above the rail bracket, three equally spaced crossbeams are installed on the inner side above the rail bracket, and an inner ring straight rail is installed on the crossbeam, and two clamping devices are installed on the other side of the inner ring straight rail, and gauge plate fixings are installed on the outer ring straight rails at both ends of the crossbeam and at both ends of the outer ring straight rails, and track oblique sealing plates are installed at both ends of the track bracket, and a right baffle is installed on the track oblique sealing plate at one end of the track bracket. The cross-belt straight rail welding fixture given in the scheme is mainly composed of a rail bracket, a gauge plate fixing, a secondary welding rod, etc. With the help of this set of fixtures, the welding master can realize single-person cross-belt straight rail welding, improve the welding efficiency of cross-belt straight rail welding, and reduce welding production costs.

[0003] However, the applicant has found that the existing tooling platforms on the market for clamping and positioning cross-strip straight rails are unable to provide targeted fixation and support for the more vulnerable local positions of the cross-rail workpieces, especially the connection positions. This can easily cause the workpieces to shake, displace, or bend and deform during the welding process, leading to reduced welding process accuracy and an increased rate of defective workpieces produced.

[0004] In view of the above problems, the utility model provides a cross-belt straight rail welding tooling specially used for positioning, connecting and fixing cross-belt straight rail workpieces during welding processing. It can stably and reliably position, clamp and fix various local positions of the cross-belt straight rail workpiece, effectively avoiding the vibration displacement of the workpiece during the welding processing, and at the same time can also carry out targeted strengthening and fixation of the weaker connection points of the workpiece, thereby improving the accuracy of the welding processing and obtaining cross-belt straight rail workpiece products with higher processing quality.

[0029] The following specific embodiments are merely explanations of the present invention and are not limitations of the present invention. After reading this specification, those skilled in the art may make modifications to the embodiments without any creative contribution as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.

[0030] This solution is achieved through the following technical means:

[0031] Embodiment: In this embodiment, a cross-belt straight rail welding tool is provided, which is specially used for positioning, connecting and fixing a cross-belt straight rail workpiece 7 during welding processing. The tool includes two parts: a main support platform 1 for supporting the cross-belt straight rail workpiece 7, and a clamping positioning component 2 arranged on the main support platform 1. The main support platform 1 includes a main body plate arranged horizontally and a plurality of vertical legs fixedly connected to the outer periphery of the bottom surface of the main body plate. On the upper part of the main support platform 1, a clamping positioning component 2 for fixing the cross-belt straight rail workpiece 7 is installed, and the clamping positioning component 2 here can be divided into two parts: a lateral limit module 3 symmetrically arranged on the left and right sides of the main support platform 1, and an end limit module 4 respectively arranged at the front and rear ends of the main support platform 1.

[0032] For details, please refer to the attached manual. Figure 3 The schematic diagram of the partial enlarged structure is given, in which the lateral limit module 3 includes a lateral positioning column 301 fixed to the upper surface of the main body supporting platform 1 and protruding vertically upward. The lateral positioning column is in the shape of an upright rectangular block, and its bottom is locked and fixed to the main body supporting platform 1 by a bolt component, and a lateral support plane 3011 facing the outside of the main body supporting platform 1 is formed on the lateral positioning column 301. Also on the upper surface of the main body supporting platform 1, an adjustable locking mechanism 302 is installed and fixed on the outside of the positioning column by a bolt component that penetrates from top to bottom. The mechanism includes a locking base 3021 for fixing to the main body supporting platform 1 and a movable support top member 3022 movably installed on the locking base 3021. It should be noted that a gap area is formed between the lateral positioning base column 301 and the adjustable locking mechanism 302 for the side portion of the cross-belt straight track workpiece 7 with the folded edge to be placed, and the movable support member 3022 can move horizontally relative to the locking base 3021 and approach or move away from the lateral support plane 3011 to achieve the conversion between the locked and released states of the side portion of the cross-belt straight track workpiece 7. For example, also refer to the attached manual Figure 3In the enlarged partial structure, the locking base 3021 is in the form of an L-shaped outward-turned sheet, the outward-turned edge portion of which is in contact with the upper surface of the aforementioned main body support platform 1 and is fixedly connected by bolts, and the upright portion extending upward is in the form of an upright parallel to the outer wall surface of the aforementioned lateral positioning base column 301. An internal threaded hole 30211 extending in the horizontal direction is provided on the upright portion extending upward of the locking base 3021, and a movable support member 3022 including a stud section 30221 corresponding to the internal thread is movably installed in the internal threaded hole 30211. At this time, the movable support member 3022 can be adjusted to move closer to or farther from the aforementioned lateral positioning base along the horizontal direction by simply rotating the movable support member 3022 in the forward and reverse directions.

[0033] The main consideration in the design of the above structure is that, for the cross-belt straight rail workpiece 7, its side portion is formed with an outwardly folded edge portion. Due to the existence of this part of the structure, the use of conventional positioning tooling will not only cause the problem of difficult clamping and fixing of the workpiece, but also easily lead to local deformation and damage. Under the structure of the lateral limit module 3 given in the partial solution of this scheme, by using the folded edge at the bottom of the workpiece as the support base, and the upright portion higher than the edge as the basis for lateral clamping and fixing, the problem of looseness and deformation during fixing can be solved, providing convenience for high-precision welding of various parts of the workpiece.

[0034] The clamping positioning assembly 2 also includes end stopper modules 4 disposed at both ends of the main body support platform 1. Similar to the lateral stopper modules 3, the end stopper modules 4 here also include an upright block component, which is installed and fixed by bolts that penetrate the main body support platform 1 and the component downward and upward, thereby achieving the purpose of stopping the cross-belt straight rail workpiece 7 in the front and rear end directions, preventing it from moving in the front and rear directions and reducing the welding quality.

[0035] Of course, since the length of the cross-belt straight rail workpiece 7 in the front and rear end directions is relatively large, a plurality of installation and connection holes 6 for fixing the aforementioned clamping and positioning components 2 should be opened in the front and rear directions of the main supporting platform 1, and the clamping and positioning components 2 should be installed at intervals at appropriate positions; of course, in order to adapt to different specifications of cross-belt straight rails with certain differences in lateral width, the aforementioned installation and connection holes 6 can also be symmetrically opened at different width spacing positions on both sides of the main supporting platform 1, so as to further expand the size specification range of the cross-belt straight rail workpiece 7 that can be installed and fixed by the tooling.

[0036] Further preferably, since a transverse rib plate 701 is also provided at the middle position of the cross-belt straight rail workpiece 7, in order to prevent the cross-belt straight rail workpiece 701 from twisting and deforming due to the force on the workpiece during the welding process, an auxiliary support column 5 for supporting the cross-belt straight rail workpiece 7 can also be provided on the main support platform 1. The auxiliary support column 5 is located at the center of the line connecting the lateral limit modules 3 on the left and right sides, and in order to further improve the support stability between it and the transverse rib plate 701, it can also be referred to the attached manual. Figure 4 As shown in the structural diagram, the top of the auxiliary supporting column 5 is provided with a downwardly recessed fitting notch 501 for the transverse rib plate 701 to be inserted into, so as to limit and fix the transverse rib plate 701 .

[0037] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the utility model, and these modifications or replacements should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
