Compared with the fixed connection by standard parts such as bolts, the advantage of the welding method is that it saves the time for drilling holes, chamfering, assembling standard parts such as bolts, and the welding method is firmly fixed, not easy to loosen, displace, and is durable.

[0003] In the prior art, a chute assembly 200 generally consists of a slide rail part 201, two chute parts 202 and two support parts 203. The chute part 202 has through holes 204 required for installation. The chute parts 202 are distributed at the lower positions at both ends of the slide rail part 201, and the two support parts 203 are distributed between the two chute parts 202 and the slide rail part 201 for connecting the chute part 202 and the slide rail part 201. During the welding and assembly process of the chute assembly 200, it is necessary to weld and fix the connection positions of the support part 203 with the slide rail part 201 and the chute part 202 to form the finished chute assembly 200.

[0004] However, at present, there is no suitable welding tooling for positioning the parts in the chute assembly during the welding and assembly of the chute assembly.

Specific implementation manner

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] The present invention provides a positioning welding tooling for combined part welding as Figures 1-4 shown, which includes a tooling base plate 100 and a plurality of compactors 101. A positioning pin assembly is provided at the top of the tooling base plate 100. The positioning pin assembly is used for positioning the chute assembly 200 on the tooling base plate 100. The plurality of compactors 101 are respectively fixedly installed at the top of the tooling base plate 100. The compactor 101 is used for pressing and positioning the chute assembly on the tooling base plate 100. The compactor 101 is a vertical quick clamp, and a vertical quick clamp with the model number GH-101-A in the prior art can be used. The positioning pin assembly can be used to separate areas on the tooling base plate 100 for positioning and placing the slide rail part 201 and the chute part 202 in the chute assembly 200, so that when the slide rail part 201 and the chute part 202 in the chute assembly 200 are assembled on the tooling base plate 100, the assembly position can be ensured to be accurate. Then, in cooperation with the compactor 101, the slide rail part 201, the chute part 202 and the support part 203 in the chute assembly 200 are pressed, ensuring the stability of the support part 203 during welding at the connection positions with the slide rail part 201 and the chute part 202. In this way, not only can the welding work efficiency of each part in the chute assembly 200 be higher, but also the splicing positions between the various parts in the chute assembly 200 are accurate, thereby improving the welding quality of the chute assembly 200.

[0023] It should be noted that the positioning pin assembly includes a slide rail member positioning pin assembly and a chute member positioning pin assembly. The slide rail member positioning pin assembly is used to limit the position of the slide rail member 201 on the tooling base plate 100. There are two sets of chute member positioning pin assemblies, which are respectively used to limit the positions of the two chute members 202 on the tooling base plate 100. In the positioning pin assembly, through the separate setting of the slide rail member positioning pin assembly and the chute member positioning pin assembly, the chute member 202 and the slide rail member 201 can be individually limited on the tooling base plate 100. In this way, the splicing position of the chute member 202 and the slide rail member 201 on the tooling base plate 100 can be made more accurate, thus helping to improve the quality of the chute assembly 200;

[0024] Among them, the slide rail member positioning pin assembly includes a first limit pin 104, a second limit pin 105 and a third limit pin 106. The second limit pin 105 is located behind the third limit pin 106. The first limit pin 104 is located between the second limit pin 105 and the third limit pin 106. The third limit pin 106 is located at the front end of the middle between the two first limit pins 104. There are two first limit pins 104 and they are arranged in parallel at intervals. There are two second limit pins 105 and they are arranged in parallel at intervals. And the distance between the two first limit pins 104 is greater than the distance between the two second limit pins 105. By using the two first limit pins 104 to limit the two ends of the slide rail member 201, then using the two second limit pins 105 to limit the back surface of the slide rail member 201, and finally using the third limit pin 106 to limit the middle part of the front surface of the slide rail member 201, the slide rail member 201 can be stably and accurately placed on the tooling base plate 100, and at the same time, the placement process is more convenient and efficient.

[0025] Among them, the chute member positioning pin assembly includes a positioning pin 103, and there are at least two positioning pins 103. When the chute member 202 is placed on the tooling base plate 100, only need to insert the through hole 204 on the chute member 202 into the corresponding positioning pin 103 in an activity manner, then the chute member 200 can be quickly and accurately positioned on the tooling base plate 100. After the chute member 202 and the slide rail member 201 are positioned on the tooling base plate 100, then place the support member 203 between the chute member 202 and the slide rail member 201, and make the outer walls of both sides of the support member 203 fit with the outer walls of the chute member 202 and the slide rail member 201. Finally, use the presser 101 to press the positions among the slide rail member 201, the chute member 202 and the support member 203, then the stability of the slide rail member 201, the chute member 202 and the support member 203 in the chute assembly 200 on the tooling base plate 100 can be ensured, and each component can be kept stable during the welding operation process, thus helping to improve the welding quality between the support member 203 and the slide rail member 201 and the chute member 202.

[0026] In a preferred embodiment, a cushion block 102 is fixedly connected to the bottom end of the compactor 101, and the bottom end of the cushion block 102 is fixedly connected to the top end of the tooling base plate 100. The arrangement of the cushion block 102 makes the installation of the compactor 101 on the tooling base plate 100 more convenient. At the same time, the cushion block 102 can keep a certain height difference between the compactor 101 and the tooling base plate 100 for installation, so as to facilitate the use in combination with the thickness of the chute assembly 200 and improve the quality of the compaction of the chute assembly 200 by the compactor 101.

[0027] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention.
