Description

Technical Field

[0001] The utility model relates to the field of welding processing, in particular to a welding platform positioning device capable of horizontal floating. Background Art

[0002] When welding a product, it is necessary to place the product on a welding platform and fix it with the fixtures on the welding platform. Then, the welding platform is transferred to the welding station to perform welding operations on the product. In the process of transferring the welding platform, some manufacturers will directly use robots or manipulators to operate. Robots or manipulators can ensure the accuracy of the placement of the welding platform, so that the workpiece can be processed directly without adjustment. However, the cost of robots is relatively high, which will cause certain cost pressures on the production and operation of the enterprise. Therefore, many enterprises still use manual lifting to transfer the welding platform. Due to the uncertainty of manual operation, the position of the welding platform needs to be adjusted after it is put in place. This is equivalent to adding an adjustment process. At the same time, this manual adjustment also has the risk of inadequate adjustment and position deviation.

[0003] Therefore, a method or device that can solve the above problems is needed. Summary of the Invention

[0004] The utility model aims to solve the above-mentioned deficiencies in the prior art and proposes a welding platform positioning device with a simple structure, ingenious design, reasonable layout, which can quickly and conveniently realize automatic adjustment of the welding platform position and ensure the accuracy of the position after adjustment.

[0005] The technical solution of the utility model is: a horizontally floating welding platform positioning device, characterized in that: the positioning device includes four positioning columns 1, adjacent positioning columns 1 are connected by a crossbeam 2, the positioning columns 1 and the crossbeam 2 together form a rectangular frame structure, the top of the positioning column 1 is fixedly supported by a lower positioning block 3, and the lower positioning block 3 is rotatably connected to a universal ball 4. The four positioning columns 1 are marked as positioning column A, positioning column B, positioning column C and positioning column D in a clockwise direction.

[0006] A cylinder bracket 5 is connected to the side walls of the positioning column A and the positioning column C. A longitudinally distributed positioning cylinder 6 is provided in the cylinder bracket 5. A positioning pin 7 is provided on the working end of the positioning cylinder 6. The top of the positioning pin 7 is conical. A longitudinally distributed first sensor 8 and a second sensor 9 are provided on the cylinder bracket 5. The first sensor 8 and the second sensor 9 correspond to the low position and the high position of the positioning pin 7, respectively.

[0007] A sensor bracket 10 is connected to the side walls of the positioning pillars B and D. The sensor bracket 10 is provided with a third sensor 11.

[0008] The positioning device further comprises a positioning hole block 13 provided on the bottom end surface of the welding platform 12, and a positioning hole 14 is provided on the positioning hole block 13, and the positioning hole 14 matches the positioning pin 7.

[0009] An upper positioning block 15 is further provided on the bottom end surface of the welding platform 12 . A groove 16 is formed on the bottom surface of the upper positioning block 15 to match the portion of the universal ball 4 protruding from the top end surface of the lower positioning block 3 .

[0010] Compared with the prior art, the utility model has the following advantages:

[0011] This horizontally floating welding platform positioning device features a simple structure, ingenious design, and rational layout. Addressing the problem of traditional welding platforms requiring fine-tuning to ensure positional accuracy after being manually transferred to the welding position, a unique floating structure has been designed. Four universal balls located at the top of the positioning posts provide the welding platform with planar freedom, while two diagonally positioned cylinders drive the positioning pins. Because the tops of the positioning pins are conical, the relative position between the welding platform and the positioning posts is automatically adjusted when the positioning pins are inserted into the positioning holes at the bottom of the welding platform, thereby achieving automatic adjustment and positioning. This positioning device allows for quick and convenient automated positioning of the welding platform, simplifying the positioning process, saving labor, and improving work efficiency. Furthermore, its simple manufacturing process and low manufacturing cost offer numerous advantages, making it particularly suitable for application in this field and promising a promising market.

[0015] The specific implementation of the present invention will be described below with reference to the accompanying drawings. Figure 1 、 Figure 2 、 Figure 3Figure 1 shows a horizontally floating welding platform positioning device, comprising four positioning columns 1. Adjacent positioning columns 1 are connected by crossbeams 2. The positioning columns 1 and crossbeams 2 together form a rectangular frame structure. A lower positioning block 3 is fixedly supported on the top of each positioning column 1. A universal ball 4 is rotatably connected to the lower positioning block 3. The four positioning columns 1 are marked as positioning column A, positioning column B, positioning column C, and positioning column D in a clockwise direction.

[0016] A cylinder bracket 5 is connected to the side walls of the positioning column A and the positioning column C. A longitudinally distributed positioning cylinder 6 is provided in the cylinder bracket 5. A positioning pin 7 is provided on the working end of the positioning cylinder 6. The top of the positioning pin 7 is conical. A longitudinally distributed first sensor 8 and a second sensor 9 are provided on the cylinder bracket 5. The first sensor 8 and the second sensor 9 correspond to the low position and the high position of the positioning pin 7, respectively.

[0017] A sensor bracket 10 is connected to the side walls of the positioning pillars B and D. The sensor bracket 10 is provided with a third sensor 11.

[0018] The positioning device further comprises a positioning hole block 13 provided on the bottom end surface of the welding platform 12, and a positioning hole 14 is provided on the positioning hole block 13, and the positioning hole 14 matches the positioning pin 7.

[0019] An upper positioning block 15 is further provided on the bottom end surface of the welding platform 12 . A groove 16 is formed on the bottom surface of the upper positioning block 15 to match the portion of the universal ball 4 protruding from the top end surface of the lower positioning block 3 .

[0020] The working process of the horizontal floating welding platform positioning device of the embodiment of the utility model is as follows: first, the workpiece to be welded is placed on the welding platform 12 and fixed with the fixture provided on the welding platform 12.

[0021] Then, use a sling or other device to move the welding platform 12 and the workpiece thereon to the rectangular frame structure formed by the positioning column 1 and the crossbeam 2, ensuring that the four upper positioning blocks 15 on the bottom end surface of the welding platform 12 fall on their corresponding lower positioning blocks 3 respectively. At this time, the universal ball 4 contacts the groove 16 on the bottom end surface of the upper positioning block 15.

[0022] When the welding platform 12 is placed in place, the third sensor 11 will detect the welding platform 12 and send a signal to the control system. The control system determines that the welding platform 12 is in place, and then sends a signal to the positioning cylinder 6. The two positioning cylinders 6 simultaneously drive the positioning pin 7 to extend, and the positioning pin 7 moves upward and is inserted into the positioning hole 14 opened on the positioning hole block 13. Since the top of the positioning pin 7 is conical, even if there is a certain deviation in the placement position of the welding platform 12, the positioning pin 7 will play a guiding role during the insertion into the positioning hole 14, and automatically drive the welding platform 12 to perform fine-tuning in the horizontal direction. When the two positioning pins 7 are all inserted into the corresponding positioning holes 14, the welding platform 12 is adjusted to the standard position. At this time, the welding platform 12 is in a precise processing position, and welding operations can be performed on the workpiece fixed thereon.

[0023] During the operation of the positioning cylinder 6 , the first sensor 8 and the second sensor 9 respectively detect the current position of the positioning pin 7 , so that the control system can determine the current working state of the positioning cylinder 6 according to the triggering conditions of the two sensors.
