Description
Technical Field
The utility model belongs to the technical field of auxiliary fixtures and specifically relates to a be used for accurate aluminum alloy combination platform welded auxiliary fixtures.
Background
In the production process of electromechanical product projects, a high-precision combined platform is often required to be processed
To achieve the weight reduction, aluminum alloy (6063) is generally required. Like the platform shown in figure 4, the outer dimension is 2050 × 1940, the grid part is made of 76 × 44 × 3 aluminum alloy square pipes (6063), and the central part is made of 12-thick aluminum plates (6063) through welding.
The combined platform has the characteristics of batch processing, has high requirements on the accuracy of welding size and angle and the consistency of products, and requires interchangeability and universality of the products. The structural characteristics of the combined platform determine the processing mode of welding.
The combination platform is performed in a mode of matching various measuring means and manual butt welding. However, due to the fact that the number of the pipes to be blanked is large, the sizes of the pipes are complicated, blanking length and angle errors and deformation of welded pieces generated in the segmented butt welding process cannot meet the precision requirement of product use, and due to the fact that welding efficiency is low, the requirement of production progress cannot be met, and the delivery period of the whole project is seriously affected.
Disclosure of Invention
An object of the utility model is to provide an auxiliary fixtures for accurate aluminum alloy combination platform welding process to solve quality problems, the efficiency problem mentioned in the above-mentioned technical background.
In order to achieve the above object, the utility model provides a following technical scheme:
the utility model provides a welded auxiliary fixtures of accurate aluminum alloy combination platform, includes locating plate 1, presss from both sides tight constant head tank 2, central positioning groove 3, quick clamping device 4, its characterized in that:
the positioning plate 1 is provided with a clamping positioning groove 2 and a central positioning groove 3, and the clamping positioning groove 2 and the central positioning groove 3 are fixedly connected with a quick clamping device 4. The positioning groove 2 and the central positioning groove 3 are formed by one-time clamping and integral processing of a processing center.
The clamping positioning groove 2 is a square groove and is crossed in a cross shape, and a square pipe is placed in the clamping positioning groove 2. The width of the positioning groove 2 is in single-side 0.05 small clearance fit with the side wall of the built-in square tube.
This auxiliary fixtures comprises locating plate and fastening a plurality of quick clamping device above it. The width of the positioning groove 2 is 44.1 plus or minus 0.02 (the corresponding dimension of the measured square tube is 44 plus or minus 0.05).
The utility model has the advantages of: the welding method is suitable for welding the aluminum alloy combined platform with characteristics of large size, batch and high precision. The auxiliary tool can perform high-precision positioning and fastening on various blanking with complicated sizes and then perform welding operation. The auxiliary tool is verified through test practice, is reasonable in design and reliable in positioning, has the characteristics of simple structure, high machining efficiency, high qualification rate and low cost, and effectively solves the problems of the welding quality and the welding efficiency of the combined platform.

Detailed Description
The structure of the utility model is further explained by combining the attached drawings of the specification.
The utility model provides a welded auxiliary fixtures of accurate aluminum alloy combination platform, includes locating plate 1, presss from both sides tight constant head tank 2, central positioning groove 3, quick clamping device 4.
The positioning plate 1 is provided with a clamping positioning groove 2 and a central positioning groove 3, and the clamping positioning groove 2 and the central positioning groove 3 are formed by one-time clamping and integral processing of a processing center. The clamping positioning groove 2 and the center positioning groove 3 are fixedly connected with a quick clamping device 4. The rapid clamping device adopts a common rapid connecting rod clamp in the current market, and the installation position and the number are adjusted according to the requirement so as to clamp a welding part.
The positioning groove 2 is a square groove and is arranged in a crossed manner. The positioning groove 2 is used for placing the square tube. The size of the positioning groove 2 is in single-side 0.05 small clearance fit with the side wall of the square tube. The gap is adjustable.
Before the combined platform is welded, the positioning plate of the auxiliary tool is horizontally placed on a cushion block with proper height, then aluminum alloy square tubes (46 and 7 sizes in the case) and central aluminum plates which are blanked and have different length sizes are correspondingly placed into the positioning grooves of the positioning plate, and then the square tubes and the central aluminum plates are respectively fastened on the positioning plate by using a quick clamping device. If the phenomenon that the length of the welding unit is out of tolerance (if the square tube is interfered and can not be placed in the welding unit) is found, the welding unit needs to be placed in the welding unit again after the length size is trimmed, and the welding process is carried out after all the square tubes and the aluminum plates are placed in the welding unit and fastened.
The combined platform welded after the auxiliary tool is positioned has the advantages that the size precision completely meets the use requirements of product drawings and parts, the interchangeability and the universality are realized, and the welding efficiency is also greatly improved. Meanwhile, welding deformation caused by errors of length and angle generated during blanking of the welding unit is avoided.
The statement of the above working principle is only the preferred embodiment of the utility model discloses a but, this welding auxiliary fixtures according to the combination platform of not unidimensional, different arrangements, can be under the condition of the position of the positioning groove of adjustment locating plate and the degree of depth, to the aluminum alloy combination formula platform that possesses jumbo size, batchization, high accuracy characteristic, implement high quality, efficient welding. All the cases are contained in the working principle framework of the utility model, which is within the protection scope of the utility model.
