[0011] Attached Figure 1 The figure is a three-dimensional structural schematic diagram of an embodiment of the utility model. DETAILED DESCRIPTION
[0012] The utility model is further described below in conjunction with the accompanying drawings.
[0013] As attached Figure 1 The positioning device of a planar welding trough structure comprises a reference plate 1, a pressing block 2 and a positioning pin 3 are arranged on the bottom surface of the reference plate 1, the pressing block 2 presses the trough structure on the welding plane of the welding target structure, the pressing block 2 is in close contact with the inner wall of the trough structure, and the positioning pin 3 is inserted and matched with the positioning hole on the welding target structure; the pressing block 2 is adapted to the width direction of the trough structure, and a plurality of pressing blocks 2 are arranged along the length direction of the trough structure.
[0014] In this solution, the pressure block and the positioning pin are connected by a reference plate, wherein the pressure block is used to cooperate with the inner cavity of the tank structure to constrain the relative position of the tank structure, and the positioning pin is used to locate the relative position of the reference plate and the welding plane. Therefore, according to the welding requirements of the tank structure, the relative position of the pressure block and the positioning pin on the reference plate is designed, and the relative position of the tank structure and the welding plane can be determined by using the positioning device. At the same time, the pressure block also plays the role of pressing and stabilizing the tank structure, ensuring that the tank structure will not move during welding, thereby ensuring the quality of welding.
[0015] The reference plate 1 is provided with a sliding guide groove, and the pressure block 2 is slidably matched with the sliding guide groove through a guide structure, and the layout trajectory of the sliding guide groove is consistent with the longitudinal axis trajectory of the trough structure. Preferably, two pressure blocks 2 are provided, and the two pressure blocks 2 are respectively arranged against the inner wall surfaces at both ends of the trough structure. It can meet the welding requirements of trough structures with different lengths relative to the trough type, and the distance between the two pressure blocks can be freely adjusted according to the length of the trough structure, so that the two pressure blocks can just be against the two end surfaces of the trough structure, and then the positioning holes can be opened on the plane according to the distance between the trough structure and the positioning pin on the positioning device. It has high versatility and convenient debugging.
[0016] The pressing block 2 and the contact surface of the tank structure are provided with an adsorption module. The adsorption device can adopt an electrically controlled magnetic suction module, which is convenient for firstly installing the tank structure with the positioning device, and then inserting the positioning device with the positioning hole, so as to ensure that the tank structure does not fall off during the process. After the welding is completed, the magnetic suction is turned off to facilitate the separation of the positioning device, making the welding process more convenient.
[0017] The outer side of the positioning pin 3 is sleeved with a limiting sleeve 4, and the limiting sleeve 4 is threadedly connected to the positioning pin 3, and the lower end surface of the limiting sleeve 4 fits the upper end surface of the positioning hole of the welding target structure. By rotating the limiting sleeve, the limiting sleeve can be adjusted along the axial direction of the positioning pin, so as to constrain the minimum spacing between the reference plate and the welding plane after the positioning pin is inserted into the positioning hole, and can be adjusted for the groove structure with different groove depths, so as to play the role of precise positioning and constraint.
[0018] The pressing block 2 can be raised and lowered in a direction perpendicular to the bottom surface of the reference plate 1, and an elastic member is sandwiched between the pressing block 2 and the reference plate 1. The pressing block is adsorbed on the bottom of the slot structure, and a gap is left between the notch and the bottom surface of the reference plate. The elastic member is at its original length. As the positioning pin is inserted into the positioning hole, the elastic member is compressed until the limit sleeve contacts the welding plane, and the notch just fits the bottom surface of the reference plate. While the pressing block applies pressure to the bottom of the slot structure, the reference plate applies pressure to the slot wall of the slot structure, and the elastic force generated by the compressed elastic member will enhance the clamping force of the pressing block, further ensuring the stability of the slot structure. Preferably, a handle can be provided on the upper end surface of the reference plate, which can be used for positioning by hand, thereby improving the convenience of welding positioning.
[0019] If the slot of the slot structure is provided with a 90° bent flange with a positioning hole, a small positioning pin can be provided at a corresponding position beside the pressing block on the reference plate to facilitate the positioning and installation of the slot structure relative to the pressing block.
[0020] The sliding guide groove can be set as two parallel lines, and the guide sliding structure is provided with an upper and lower clamping plates, wherein the lower clamping plate is provided with a column cooperating with the sliding guide groove, and the upper clamping plate is provided with a through hole for the column to pass through, and the top of the column is connected with a locking nut through a threaded cooperation, and by tightening the nut, the upper and lower clamping plates can clamp the reference plate, thereby achieving fixed position of the pressure block, conversely, loosening the nut can adjust the position of the pressure block; wherein, the bottom surface of the lower clamping plate is connected to the pressure block through the elastic member, and the elastic member is sleeved on the outside of the guide rod, the guide rod is fixedly connected to the upper end surface of the pressure block, and the guide rod is vertically arranged, and the lower clamping plate is provided with a guide hole cooperating with the guide rod sliding, and the guide hole is opened on the axis of the column, which can guide the lifting and lowering movement of the pressure block, so that the lifting and lowering of the pressure block is more stable.
[0021] The above are only preferred embodiments of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
