[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0029] Please refer to Figures 1 to 6 :
[0030] Example 1: This utility model proposes a positioning device for welding axle housings, comprising: a stabilizer 1, which is a rectangular frame structure, with two positioning vertical plates 101 installed on the rear side of the stabilizer 1, and a bracket 102 installed at the middle position of the top of both ends of the stabilizer 1; a rotating screw 103 is rotatably installed between the two positioning vertical plates 101, and a servo motor is installed on the outer side of one positioning vertical plate 101, with the output end of the servo motor connected to one end of the rotating screw 103; drive gears 104 are installed on both ends of the rotating screw 103; a rotating wheel 105 is rotatably installed at the middle position of the bracket 102; a transmission gear 106 is installed on the side end of the rotating wheel 105; and a sliding contact is formed between the rotating wheel 105 and the transmission gear 106. A traction slide bar 107 is mounted on the traction slide bar 107; a positioning plate 109 is mounted on the inner end of the traction slide bar 107; two fixing plates 1012 are slidably mounted on the inner side of the positioning plate 109; the outer side of the transmission gear 106 is meshed with the outer side of the drive gear 104; a drive cylinder is mounted on the outer side of the bracket 102, and a traction plate 108 is fixedly mounted on the output end of the drive cylinder; one side of the top of the traction plate 108 is rotatably connected to the outer end of the traction slide bar 107; a guide rod 1010 is mounted on one side of the positioning plate 109, and a drive screw 1011 is rotatably mounted on the other side of the positioning plate 109; the middle position of the fixing plate 1012 is an arc-shaped structure, and the two ends of the fixing plate 1012 are respectively mounted on the outer side of the guide rod 1010 and the drive screw 1011.
[0031] In this embodiment, when positioning the axle housing during welding, the position between the two positioning plates 109 is adjusted according to the length of the axle housing. The drive cylinder on the outer side of the bracket 102 drives the traction plate 108 to move. The traction plates 108 in both directions drive the traction slide rod 107 to slide in the middle position between the rotating wheel 105 and the transmission gear 106. Then, the traction slide rod 107 drives the inner positioning plate 109 to move, so that the two positioning plates 109 are at a suitable distance. On the other side of the positioning plate 109, the drive screw 1011 is rotated to drive the fixing clamp 1012 to move along the guide rod 1010. The two fixing clamps 1012 are positioned at both ends of the axle housing. For positioning, a servo motor on the outer side of the positioning vertical plate 101 drives the rotating screw 103 to rotate. The two ends of the rotating screw 103 drive the drive gear 104 to mesh with the drive gear 106 to rotate. The drive gear 106 drives the rotating wheel 105 to rotate in the middle position of the bracket 102. The rotating wheel 105 and the drive gear 106 then drive the traction slide 107 to rotate. The traction slide 107 then drives the axle housing fixed by the fixed clamp 1012 to rotate, which facilitates the flipping of the welding position and ensures the welding quality of the axle housing. The entire flipping process does not require manual flipping, which saves time and effort and improves the welding efficiency of the axle housing.
[0032] In Example 2, based on Example 1, a fixing frame 2 is installed on the top of the positioning vertical plate 101 and the bracket 102; a drive cylinder is installed at one end of the fixing frame 2, and an air pump is installed at the other end of the fixing frame 2; two positioning rods 201 are installed on the inner side of the fixing frame 2; a guide slide plate 202 is slidably installed on the outer side of the two positioning rods 201; the side of the guide slide plate 202 is connected to the output end of the drive cylinder at one end of the fixing frame 2; an air jet pipe 203 is installed at the bottom of the guide slide plate 202, wherein the bottom of the air jet pipe 203 has multiple slots; a guide pipe 204 is installed on the output end of the air pump at the other end of the fixing frame 2; the side end of the guide pipe 204 is connected to the side of the air jet pipe 203. The inner side of the stabilizer 1 is equipped with a collection cover 205. During the welding process, when the axle housing is positioned, the airflow generated by the air pump at the other end of the fixed frame 2 enters the interior of the jet pipe 203 through the guide pipe 204. The output end of the drive cylinder at one end of the fixed frame 2 drives the guide slide plate 202 to move along the two positioning rods 201. The guide slide plate 202 then drives the airflow ejected from the bottom jet pipe 203 toward the welded area, which cools the welded area in time. The airflow blows downward, blowing the weld slag that splashes out after the thermal expansion and contraction of the welded area downward, so that the weld slag falls into the collection cover 205 for storage, reducing the problem of weld slag splashing to other places.
[0033] In Example 3, based on Example 1, a guide crossbar 3 is installed between the two positioning vertical plates 101, and a rotating screw 301 is rotatably installed between the two positioning vertical plates 101. A drive motor is installed on the outside of another positioning vertical plate 101, and the output end of the drive motor is connected to one end of the rotating screw 301. A movable plate 302 is installed on the rotating screw 301. The movable plate 302 has an L-shaped structure and is also slidably installed on the outside of the guide crossbar 3. A drive cylinder is installed on the side end of the movable plate 302. A support plate 303 is installed on the output end of the drive cylinder. When the axle housing is positioned during the welding process, the drive motor on the outside of another positioning vertical plate 101 drives the rotating screw 301 to rotate. The rotating screw 301 drives the movable plate 302 to slide along the outside of the guide crossbar 3, so that the movable plate 302 moves to the appropriate position. Then, the drive cylinder on the side of the movable plate 302 drives the support plate 303 to move upward, so that the support plate 303 supports the components of the axle housing, ensuring the stability of the welding process and ensuring the quality of the axle housing welding.
[0034] The working principle of this embodiment is as follows: The drive cylinder on the outside of the bracket 102 drives the traction plate 108 to move. The traction plates 108 in two directions drive the positioning plate 109 at the inner end of the traction slide rod 107 to move. The two positioning plates 109 are at a suitable distance. The rotating drive screw 1011 drives the fixed clamping plate 1012 to move along the guide rod 1010. The two fixed clamping plates 1012 position the two ends of the axle housing. The drive motor on the outside of another positioning vertical plate 101 drives the rotating screw 301 to drive the movable plate 302 to slide along the guide crossbar 3. The movable plate 302 moves to a suitable position. The drive cylinder on the side of the movable plate 302 drives the support plate 303 to move upward to support the components of the axle housing and ensure stability during the welding process. After one side is welded, the outer side of one positioning vertical plate 101... The servo motor drives the rotating screw 103 and the drive gear 104 to mesh and drive the transmission gear 106 to rotate. The transmission gear 106 drives the rotating wheel 105 to rotate in the middle position of the bracket 102. The rotating wheel 105 and the transmission gear 106 drive the traction slide 107 to rotate. The traction slide 107 drives the axle housing fixed by the fixed clamp 1012 to rotate, which facilitates the flipping of the welding position. The airflow generated by the air pump enters the jet pipe 203 through the guide pipe 204. The output end of the drive cylinder at one end of the fixed frame 2 drives the guide slide 202 to move along the two positioning rods 201. The guide slide 202 drives the airflow ejected from the jet pipe 203 at the bottom to move towards the welding completed position, so as to cool down the welded position in time. The airflow blows downward and causes the welding slag to fall into the collection cover 205 for storage.
