Figure 3 This is a structural schematic diagram of the fixing component according to the first embodiment of this utility model. Figure 4 This is a schematic diagram of the material pressing assembly according to the first embodiment of the present invention. The present invention provides a welding auxiliary tooling, including a base 101, a positioning assembly, a fixing assembly, and a material pressing assembly. The positioning assembly includes a support frame 102, a tapered pin 103, a positioning rod 104, a fixing cone 105, a discharge cylinder 106, and a discharge rod 107.

The aforementioned solution solves the problem that the positioning holes of the workpiece have tolerances, and the two fixed positioning pins can only be smaller than the positioning holes of the workpiece. The holes of each workpiece will be of different sizes, which will lead to excessive tolerances in the welded workpieces.

[0020] In this specific embodiment, there are two support frames 102, each fixedly connected to the base 101 and located at the top of the base 101. There are multiple tapered pins 103, each detachably connected to the support frame 102 and located at the top of the support frame 102. There are two positioning rods 104, each detachably connected to the support frame 102 and located on the inner side of the support frame 102. There are two fixing cones 105, each detachably connected to the support frame 102 and located at the top of the support frame 102. The fixing assembly and the pressing assembly are connected to the base 101, which provides support for the device. The positioning assembly and the workpiece to be welded provide support. A spring is provided in the middle of the connection between the tapered pin 103 and the support frame 102 for positioning the workpiece to be welded. The positioning rod 104 and the fixing cone 105 are used to position the workpiece. Before welding, the lower half of the workpiece to be welded is placed outside the tapered pin 103, the positioning rod 104 and the fixing cone 105. The tail of the tapered pin 103 is spring-loaded and can move up and down slightly. The tapered pin 103 will be compressed to the corresponding position according to the different sizes of the positioning holes, so that the positioning is more accurate and can reduce the problem of excessive tolerance caused by different sizes of positioning holes. After positioning, the fixed assembly is used to fix the positioned part, and then the pressing assembly is used to press down the upper half of the part to be welded, so that the two parts fit together and facilitate welding.

It also includes two discharge rods 107, each connected to one of the discharge cylinders 106 and passing through the base 101. The discharge cylinders 106 provide power to the discharge rods 107, which are used to discharge the welded workpiece. After welding, the clamping cylinder 120, the fixing cylinder 109, and the pressing cylinder 116 are sequentially released from their positions. Then, the discharge cylinders 106 push the discharge rods 107 to extend, pushing the workpiece out from the outside of the tapered pin 103, the positioning rod 104, and the fixing cone 105, facilitating workpiece discharge.

[0022] Secondly, the fixing seat 108 is fixedly connected to the base 101 and located on top of the base 101. The fixing cylinder 109 is fixedly connected to the fixing seat 108 and passes through the base 101. The fixing push rod 110 is connected to the fixing cylinder 109 and passes through the fixing seat 108. The connecting seat 111 is fixedly connected to the fixing push rod 110 and located on top of the fixing push rod 110. The fixing seat 108 provides support for the fixing assembly. The fixing cylinder 109 provides power to the fixing push rod 110. The fixing push rod 110 drives the connecting seat 111 and the fixing plate 113. The connecting seat 111 provides a limit for the fixing plate 113.

[0023] Furthermore, the connecting plate 112 is rotatably connected to the fixed seat 108 and located on top of the fixed seat 108. The fixed plate 113 is rotatably connected to the connecting seat 111 and located on top of the connecting plate 112. There are two fixing frames 114, which are respectively fixedly connected to the fixed plate 113 and located at the bottom of the fixed plate 113. The connecting plate 112 is used to limit the fixed plate 113, and the fixed plate 113 provides a transmission function for the fixing frame 114. The fixing frame 114 is used to press the workpiece onto the surface of the support frame 102. After the workpiece is positioned, the fixing cylinder 109 pushes the fixing push rod 110 to extend, while simultaneously driving the connecting seat 111 and the fixing plate 113 to rotate along the connecting plate 112, and simultaneously driving the fixing frame 114 to press the workpiece onto the surface of the support frame 102.

[0024] Finally, the support base 115 is fixedly connected to the base 101 and located on top of the base 101; the pressing cylinder 116 is fixedly connected to the support base 115 and located on top of the support base 115; the pressing rod 117 is connected to the pressing cylinder 116 and located at the bottom of the pressing cylinder 116; the lifting seat 118 is fixedly connected to the pressing rod 117 and located at the bottom of the pressing rod 117; there are two clamping cylinders 120, each fixedly connected to the pressing seat 119 and located on the outside of the pressing seat 119; there are four clamping seats 121, each connected to the clamping cylinder 120 and located at the bottom of the clamping cylinder 120; the support base 115 provides support for the pressing assembly; and the pressing cylinder 116 is used to press... The material rod 117 and the lifting seat 118 provide power. The pressure rod 117 is used to provide transmission to the lifting seat 118. The lifting seat 118 provides support for the pressure seat 119 and the clamping cylinder 120. The pressure seat 119 is used to press the workpiece away from the fixed frame 114. The clamping cylinder 120 is used to control the clamping seat 121. After the lower part to be welded is fixed, the other half of the part to be welded is placed in the middle of the clamping seat 121. The clamping cylinder 120 pushes the clamping seat 121 to clamp, clamping the part in the middle of the clamping seat 121. The pressure rod 117 is pushed downward by the pressure cylinder 116, which at the same time drives the lifting seat 118 to descend, and at the same time drives the pressure seat 119 and the clamping cylinder 120 to move downward, so as to facilitate the clamping of the two workpieces to be welded together.

[0025] Using the welding auxiliary fixture of this embodiment, the base 101 provides support for the device, the support frame 102 provides support for the positioning component and the workpiece to be welded, and a spring is provided in the middle of the connection between the tapered pin 103 and the support frame 102 for positioning the workpiece to be welded. The positioning rod 104 and the fixing cone 105 are used to position the workpiece. Before welding, the lower half of the workpiece to be welded is placed outside the tapered pin 103, the positioning rod 104, and the fixing cone 105. The tail of the tapered pin 103 has a spring that can move up and down slightly. The tapered pin 103 moves and compresses to the corresponding position according to the different sized positioning holes, making the positioning more accurate and reducing the problem of excessive tolerance caused by inconsistent positioning hole sizes. After positioning, the fixed component facilitates the fixation of the positioned parts, and the pressure component presses down the upper part of the part to be welded, so that the two parts fit together, which facilitates the welding of the parts. This solves the problem that the positioning holes of the workpiece will have tolerances, and the two fixed positioning pins can only be smaller than the positioning holes of the workpiece. The holes of each workpiece will be of different sizes, which will lead to excessive tolerances in the welded workpieces.
