Description

Technical Field

[0001] The utility model relates to the technical field of vehicle aluminum shell production, in particular to an aluminum welding shell anti-deformation tool. Background Art

[0002] Aluminum alloy shells are widely used in automotive parts, and aluminum welding is required when processing the shells. In the aluminum welding production line, the shell needs to be positioned, and it is usually positioned and clamped only by pressing against the welding surface. However, aluminum has strong ductility and is easy to deform. Most of the processed shells are of different rules. During positioning and welding operations, the welding surface is pressed, and the side wall of the shell is prone to deformation. In addition, the thickness of each part of the shell is different due to different processing parameters. During the positioning process, the shell will also be deformed, and even damaged, affecting the yield rate.

[0003] Therefore, in order to solve the above problems, it is necessary to further improve the structure of the aluminum shell positioning device to prevent deformation of the shell during the positioning process. Utility Model Content

[0004] The utility model aims to provide an anti-deformation tool for an aluminum welding shell, which can enhance the positioning effect of the shell and prevent the shell from deforming.

[0005] In order to achieve the above-mentioned utility model purpose, the utility model provides an aluminum welding shell anti-deformation tooling, including a workbench, a downward pressure cylinder, a side pressure cylinder, a contour seat, a pressure gauge, and a solenoid valve;

[0006] The profiling seat is located on the workbench, and the downward pressure cylinder and the side pressure cylinder are both located around the profiling seat;

[0007] The downward pressure oil cylinder is connected with a pressure plate, and the pressure plate is located above the profiling seat; the side pressure oil cylinder is connected with a pressure rod, and the pressure rod faces the side wall of the profiling seat;

[0008] The profiling seat is composed of a plurality of profiling blocks, each of which is provided with an adjustment hole, and a fastener connects the profiling block to the workbench through the adjustment hole;

[0009] There are a plurality of the downward pressure cylinders and the side pressure cylinders, and each of the downward pressure cylinders and the side pressure cylinders is correspondingly connected to the pressure gauge and the solenoid valve.

[0010] Preferably, the fastener is a countersunk screw.

[0011] As a further improvement of the utility model, the workbench is provided with a feeding sensor, and the induction head of the feeding sensor faces the contour seat.

[0012] As a further improvement of the utility model, the piston rod of the downward pressure cylinder is provided with a connecting rod, and the downward pressure cylinder is connected to the pressure plate through the connecting rod.

[0013] As a further improvement of the utility model, the pressure rod is provided with a rubber block.

[0014] As a further improvement of the utility model, the side wall of the workbench is provided with a docking block, and the docking block is provided with an interface.

[0015] The utility model discloses an anti-deformation tool for aluminum welding shell. The inner wall of the shell is sleeved on the profiling seat, the welding surface of the shell faces upward, and the height of the corresponding profiling blocks is adjusted in advance by fasteners according to the thickness of each part of the shell of the same batch, so that each profiling block fits each part of the shell to ensure uniform pressure. After debugging, the telescopic rod of the downward pressure oil cylinder descends, and each corresponding pressing plate presses down the welding surface of the shell at the corresponding position to position the shell, so as to avoid sliding of the shell during welding operation and affecting the welding effect. The side pressure oil cylinder extends the pressure rod to press the side wall of the shell against the side of the profiling seat, so as to avoid that only the top of the shell is stressed, resulting in the side wall of the shell being squeezed and deformed. The pressure gauge can measure the pressure of the oil circuit connected thereto, and is connected to the corresponding solenoid valve. After receiving the pressure value measured by the pressure gauge, the terminal control box sends an instruction to the solenoid valve to control the oil volume of the oil circuit to always be within a preset range, thereby controlling the pressure of each downward pressure oil cylinder and the side pressure oil cylinder on the shell, so as to avoid excessive pressure to damage the shell, and to avoid excessive pressure to affect the positioning effect of the shell.

[0016] Compared with the prior art, the utility model has the following advantages:

[0017] (1) The downward pressure cylinder and the side pressure cylinder improve the positioning effect of the shell and prevent the shell from being deformed by pressure to a certain extent. The pressure on the shell is automatically controlled by the solenoid valve;

[0018] (2) The split-type profiling block has greater mobility and flexibility, and can adapt to the positioning requirements of shells of different shapes and wall thicknesses, so that the shell is subjected to uniform force, thereby avoiding the shell being damaged by the uniform force.

[0024] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.

[0025] like Figure 1-2 As shown, the utility model is an anti-deformation tool for aluminum welding shell, comprising a workbench 1, a downward pressure cylinder 2, a side pressure cylinder 3, a contour seat 4, a pressure gauge 5, and a solenoid valve 6;

[0026] The profiling seat 4 is located on the workbench 1, and the downward pressure cylinder 2 and the side pressure cylinder 3 are both located around the profiling seat 4;

[0027] The pressing cylinder 2 is connected to a pressing plate 21, which is located above the contour seat 4; Figure 3 As shown, the side pressure oil cylinder 3 is connected to a pressure rod 31, and the pressure rod 31 faces the side wall of the contour seat 4;

[0028] like Figure 4 As shown, the profiling seat 4 is composed of a plurality of profiling blocks 41, and the profiling blocks 41 are provided with adjustment holes 42, and the fasteners 43 connect the profiling blocks 41 to the workbench 1 through the adjustment holes 42;

[0029] There are a plurality of downward pressure cylinders 2 and side pressure cylinders 3 , and each downward pressure cylinder 2 and side pressure cylinder 3 is correspondingly connected with a pressure gauge 5 and a solenoid valve 6 .

[0030] The utility model discloses an anti-deformation tool for aluminum welding shell. The inner wall of the shell 9 is sleeved on the profiling seat 4, the welding surface of the shell 9 faces upward, and the corresponding profiling blocks 41 are adjusted in height in advance through fasteners 43 according to the thickness of each part of the shell 9 of the same batch, so that each profiling block 41 fits each part of the shell 9 to ensure uniform pressure; after debugging, the telescopic rod of the pressing oil cylinder 2 is lowered, and each corresponding pressing plate 21 presses down the welding surface of the shell 9 at the corresponding position to position the shell 9, so as to avoid sliding of the shell 9 during welding operation and affect the welding effect; the side pressure The oil cylinder 3 extends the pressure rod 31 to press the side wall of the shell 9 against the side of the contoured seat 4 to avoid that only the top of the shell 9 is subjected to force, causing the side wall of the shell 9 to be squeezed and deformed; the pressure gauge 5 can measure the pressure of the oil circuit connected to it and is connected to the corresponding solenoid valve 6. After the terminal control box receives the pressure value measured by the pressure gauge 5, it sends an instruction to the solenoid valve 6 to control the oil amount in the oil circuit to always be within the preset range, thereby controlling the pressure of each downward pressure cylinder 2 and side pressure cylinder 3 on the shell 9 to avoid excessive pressure and damage to the shell, and avoid too little pressure and affect the positioning effect of the shell.

[0032] The piston rod of the pressing oil cylinder 2 is provided with a connecting rod 22, and the pressing oil cylinder 2 is connected to the pressing plate 21 through the connecting rod 22. When the piston rod of the pressing oil cylinder 2 is extended and retracted, the connecting rod 22 hinged thereto rotates, so that the pressing plate 21 opens and closes accordingly. In the conventional connection structure, the pressing plate 21 is always located above the contour seat 4 and rises and falls, affecting the loading and unloading of the shell 9. The connection mode in which the pressing plate 21 rotates with the connecting rod 22 can provide an operating space for loading and unloading of the shell 9.

[0033] The pressure rod 31 is provided with a rubber block 32, which directly contacts the surface of the shell 9 instead of the pressure rod 31.

[0034] The fastener 43 for fixing the contour block 41 is generally a screw, and the fastener 43 is preferably a countersunk screw. The head of the fastener 43 can be located in the adjustment hole 42 to prevent the protruding fastener 43 from protruding and affecting the positioning of the housing 9.
