[0001] This utility model relates to the field of three-way catalytic converter technology, and in particular to a three-way catalytic converter carrier forming device. Background Technology

[0002] With the rapid development of the automotive industry, the requirements for vehicle exhaust emissions are becoming increasingly stringent. As a key component for reducing harmful emissions from vehicle exhaust, the assembly quality and performance of the three-way catalytic converter are of paramount importance.

[0003] Currently, in the assembly process of three-way catalytic converters, the forming of the carrier is a key step. Existing three-way catalytic converters require welding assembly during forming, which requires the use of three-way catalytic converter fixing fixtures. The fixing fixtures fix the outer shell, intake manifold and exhaust manifold of the three-way catalytic converter to facilitate subsequent welding and forming.

[0004] However, in the implementation of existing three-way catalytic converter fixing fixtures, at least the following technical problems have been found: Most of the existing three-way catalytic converter fixing fixtures are customized in advance according to the product, and most of them can only fix one type of three-way catalytic converter. It is not easy to fix three-way catalytic converter parts of different sizes or lengths. When fixing three-way catalytic converters of different models, there is a problem of incompatibility.

[0025] This application provides a three-way catalytic converter carrier forming device, which effectively solves the problem that existing devices are not easy to fix three-way catalytic converter parts of different sizes and have low applicability.

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the technical solution in this application embodiment effectively solves the technical problem that existing devices are not easy to fix three-way catalytic converter parts of different sizes and have low applicability. The overall idea is as follows:

[0027] To address the problems existing in the prior art, this utility model provides a three-way catalytic converter carrier forming device, including a base plate 1. A first guide groove 101 is formed on the top surface of the base plate 1, and four second guide grooves 102 are formed on the top surface of the base plate 1. Three of the second guide grooves 102 are located on one side of the first guide groove 101, and the other second guide groove 102 is located on the other side of the first guide groove 101. A clamping mechanism 2 is slidably connected to the first guide groove 101, and a supporting mechanism 3 is slidably connected to each of the four second guide grooves 102. The clamping mechanism 2 includes a first T-shaped slider 201 and a hexagonal nut 5, and the supporting mechanism 3 includes a second T-shaped slider 301 and a hexagonal bolt 4.

[0028] The first T-shaped slider 201 is slidably connected to the first guide groove 101. The first T-shaped slider 201 is fixedly connected to the connecting plate 202. The connecting plate 202 has a threaded groove 203 on its surface. The hexagonal nut 5 is threadedly connected to the inside of the threaded groove 203. The hexagonal nut 5 is pressed and connected to the top surface of the base plate 1.

[0029] The first T-shaped slider 201 is fixedly connected to a placement plate 204 at one end away from the first guide groove 101, and both ends of the placement plate 204 away from the first T-shaped slider 201 are fixedly connected to a fixing plate 205.

[0030] Two springs 206 are fixedly connected to the adjacent sides of the two fixed plates 205. A clamping plate 207 is fixedly connected to the end of the spring 206 away from the fixed plate 205. A friction plate 208 is fixedly connected to the side of the clamping plate 207 away from the spring 206.

[0031] The second T-shaped slider 301 is slidably connected to the inner side of the second guide groove 102. The surface of the second T-shaped slider 301 is provided with a square groove 302 and a limiting groove 303. A limiting slider 304 is slidably connected in the limiting groove 303. A threaded bolt 305 is fixedly connected at the axis of the limiting slider 304.

[0032] The threaded bolt 305 is located inside the square groove 302. One end of the threaded bolt 305 is fixedly connected to the support plate 306. The top surface of the support plate 306 has a semi-circular groove. The end of the threaded bolt 305 away from the support plate 306 is threadedly connected to the hexagonal bolt 4.

[0033] By providing a movable clamping mechanism 2 and a supporting mechanism 3, when different three-way catalytic converter parts need to be fixed, the hexagonal nut 5 can be loosened to disengage it from the top surface of the base plate 1. Then, the first T-shaped slider 201 can move within the first guide groove 101, thereby moving the overall position of the two clamping mechanisms 2 to accommodate housings of different lengths. Subsequently, each supporting mechanism 3 can slide on the second guide groove 102 via the second T-shaped slider 301 to accommodate manifolds of different shapes. Furthermore, by loosening the hexagonal bolt 4, the threaded bolt 305 can disengage from the supporting plate 306, allowing the supporting plate 306 to move on the second T-shaped slider 301. The limiting slider 304 serves as a guide and limiter to accommodate manifolds of different shapes, making this application highly applicable and solving the technical problem that existing devices are not easy to fix three-way catalytic converter parts of different sizes, resulting in low applicability.

[0034] Working principle:

[0035] The first step is to place the outer casing of the three-way catalytic converter on top of the two placement plates 204. The clamping plate 207 clamps the two sides of the outer casing, and the friction plate 208 increases the friction. The spring 206 is used to push the clamping plate 207 to clamp the outer casing. After the outer casing is fixed, the intake manifold is placed on the support mechanism 3 that slides on the single second guide groove 102 and is supported by the support plate 306. The exhaust manifold is placed on the support mechanism 3 that slides on the three common second guide grooves 102 and is supported by the support plate 306. This completes the support of each part of the three-way catalytic converter. At this time, the various parts of the three-way catalytic converter can be welded.

[0036] The second step involves fixing different three-way catalytic converter parts. This can be done by loosening the hexagonal nut 5 to disengage it from the top surface of the base plate 1. Then, the first T-shaped slider 201 can move within the first guide groove 101, thereby moving the overall position of the two clamping mechanisms 2 to accommodate housings of different lengths. Subsequently, each supporting mechanism 3 can slide on the second guide groove 102 via the second T-shaped slider 301 to accommodate manifolds of different shapes. Furthermore, by loosening the hexagonal bolt 4, the threaded bolt 305 can be disengaged from the support plate 306, allowing the support plate 306 to move on the second T-shaped slider 301. The limiting slider 304 serves as a guide and limiter to accommodate manifolds of different shapes.

[0037] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
