Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.
[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," "fixed connection," and "fixed connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0019] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings and preferred embodiments.
[0020] like Figs. 1-3 As shown, a DeLaval tool splicing device includes a base 1, a support plate 2, a first support seat 3, a second support seat 4, a first clamp 5, and a second clamp 6. The bottoms of the first and second support seats are fixed to the base by the support plate. The first support seat is used to support the square tube 001. The first clamp is fixed to the base and is used to clamp the square tube. The first support seat is provided with four first positioning pins 7, which are used to position the square tube 001. The second support seat is provided with limiting grooves 8 on both sides, which are used to limit the side plates 002. There are two second clamps, which are fixed to both sides of the base and are used to clamp the two side plates so that the side plates are tightly attached to the square tube 001. The bottom of the second support seat is provided with a stepped platform 9, which is used to support the lower connecting seat 004. The second positioning pin 10 passes through the lower connecting cap and the lower connecting seat and positions them on the side of the second support seat. The third positioning pin 11 passes through the upper connecting cap and the upper connecting seat and positions them on the upper part of the second support seat.
[0021] When using, place the square tube horizontally on the first support seat, and make the positioning holes at the bottom of the square tube correspond to and accurately align with the four first positioning pins on the first support seat. During placement, handle it gently to avoid damage to the positioning pins or deviation of the positioning holes of the square tube.
[0022] Operate the first pressing clamp and gradually press the pressing surface of the first pressing clamp downward by rotating the handle or other operation methods until it uniformly presses the top of the square tube. Check whether the square tube is firmly fixed without shaking or loosening to ensure that the square tube maintains a stable position during subsequent operations.
[0023] Insert the two side plates from the entrance of the limiting groove of the second support seat respectively. Since the 30° chamfer is provided at the entrance of the limiting groove, it can guide the side plates to smoothly enter the groove. During insertion, pay attention to the direction and position of the side plates to ensure that they are accurately embedded at the bottom of the limiting groove.
[0024] Start the second pressing clamp (if it is a pneumatic pressing clamp, turn on the gas source switch; if it is other types of pressing clamp, operate according to the corresponding operation method), and the pressing heads on both sides will extend synchronously and press the outside of the side plates. Adjust the pressure of the pressing clamp to make the side plates tightly fit the side surface of the square tube, ensuring that the side plates are firmly installed and accurately positioned.
[0025] Place the lower connecting seat stably on the stepped platform at the bottom of the second support seat to ensure that the bottom surface of the lower connecting seat completely matches the top surface of the stepped platform. This can provide stable support for the lower connecting seat and ensure its positional accuracy during welding.
[0026] Sleeve the lower connecting cap onto the second positioning pin on the side of the second support seat to make the positioning hole of the lower connecting cap accurately align with the positioning hole of the lower connecting seat. During sleeving, operate slowly to avoid collision between the positioning pin and the positioning hole, which may cause damage.
[0027] Place the upper connecting seat on the top of the second support seat, again ensuring that it is placed stably and accurately positioned.
[0028] Sleeve the upper connecting cap onto the third positioning pin on the upper part of the second support seat to make the positioning hole of the upper connecting cap align with the positioning hole of the upper connecting seat. Check the installation of the connecting seat and the connecting cap to ensure that they are tightly matched and accurately positioned.
[0029] Weld according to the principle of easy first and important second. Preferentially weld the connection between the square tube and the side plate, and use the method of symmetrical welding to start from both ends of the square tube to the middle to reduce thermal deformation during welding. When welding, keep the angle of the welding gun stable and perpendicular to the workpiece surface, and adjust the welding current and voltage parameters reasonably according to the thickness and material of the workpiece to ensure good weld quality.
[0030] After the welding of the side plate and the side plate and the upper and lower connecting seat is welded, the connecting part of the connecting seat and the connecting cap is welded. Similarly, the symmetrical welding method is adopted to ensure the strength and stability of the connecting part.
[0031] Finally, the connecting part of the connecting seat and the connecting cap is welded. During the welding process, attention should be paid to controlling the welding speed and penetration to avoid defects such as pores, cracks, etc.
[0032] It should be pointed out that for those skilled in the art, without departing from the principle of the present application, a number of improvements and refinements can be made, which should be considered as the protection scope of the present application.
