[0002] Due to the irregular structure of the knuckle, it is difficult to clamp it well during clamping. For example, Figure 1 For the shown knuckle, three bearings need to be installed. After installing one bearing, its position needs to be transferred for the installation of the other bearings. Due to the irregular structure of the knuckle, it cannot be effectively clamped. If a device can be designed to ensure the effective clamping of the knuckle, it is a problem that we need to solve. Summary of the Invention

[0003] The purpose of the present invention is to provide a knuckle positioning and clamping device to solve the problem of difficult clamping of irregular knuckles in the prior art.

[0004] To achieve the above purpose, the present invention is implemented by the following technical solutions:

[0014] According to the above technical solution, the embodiments of the present invention have at least the following effects:

[0015] 1. For the clamping device designed in this application, a positioning rod and a positioning head are designed. When clamping the steering knuckle, the connecting main board descends to drive the positioning head at the end of the positioning rod to insert into the two positioning holes of the steering knuckle. At this time, the positioning clamping claws at the end of the clamping rod are located in the gap groove of the steering knuckle. Start the jaw cylinder, and the jaw cylinder drives the clamping rod to rotate, and the positioning clamping claws clamp the surface in the gap groove of the steering knuckle; through the combined action of the positioning rod and the positioning clamping claws, the clamping effect on the steering knuckle is ensured.

[0016] 2. This application also designs a moving cylinder. The jaw cylinder is installed at the output end of the moving cylinder.

[0024] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0025] It should be noted that in the description of the present invention, the orientation or positional relationship indicated by the terms "front", "rear", "left", "right", "upper", "lower", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and does not require the present invention to be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present invention. The terms "front", "rear", "left", "right", "upper", "lower" used in the description of the present invention refer to the directions in the drawings, and the terms "inner" and "outer" refer to the directions towards or away from the geometric center of a specific component respectively.

[0026] As Figures 1 to 6 shown, a knuckle positioning and clamping device includes a connecting main board 1. Two positioning rods 2 are connected to the bottom surface of the connecting main board 1, and positioning heads 3 are provided at the ends of the positioning rods 2. A jaw cylinder 4 is connected to the top surface of the connecting main board 1. The jaw cylinder 4 is provided with two output jaws, and each jaw is connected to a clamping rod 5. The clamping rod 5 penetrates to the bottom of the connecting main board 1 and is connected to a positioning and clamping jaw 6. When the connecting main board 1 descends, the positioning head 3 at the end of the positioning rod 2 is inserted into the positioning holes of the knuckle, and the jaw cylinder 4 drives the clamping rod 5 to rotate to clamp the knuckle.

[0027] For the clamping device designed in this application, the positioning rod 2 and the positioning head 3 are designed. When clamping the knuckle, the connecting main board 1 descends to drive the positioning head 3 at the end of the positioning rod 2 to be inserted into the two positioning holes of the knuckle. At this time, the positioning and clamping jaw 6 at the end of the clamping rod 5 is located in the clearance groove of the knuckle. The jaw cylinder 4 is started, and the jaw cylinder 4 drives the clamping rod 5 to rotate, and the positioning and clamping jaw 6 clamps the surface in the clearance groove of the knuckle. Through the combined action of the positioning rod 2 and the positioning and clamping jaw 6, the clamping effect on the knuckle is ensured.

[0028] The structure of the knuckle is as Figure 1 shown. It has two positioning holes, and a clearance groove is provided in the middle of the two positioning holes. The clamping device designed in this application is for the purpose of being able to adjust the position of the knuckle when installing bearings on the knuckle to ensure the rapid installation of three bearings on the knuckle. After clamping the knuckle through this application and rotating the knuckle, the bearing mounting holes on the knuckle can be aligned with the bearing mounting station to ensure the smooth installation of the bearings.

[0029] Specifically, the positioning and clamping device of this application is as Figures 2 to 6 shown. It includes a connecting main board 1 and a mounting board 8. The connecting main board 1 and the mounting board 8 are connected by connecting rods, so that there is a certain distance between the connecting main board 1 and the mounting board 8, and devices such as the jaw cylinder 4 and the moving cylinder 7 can be installed between them.

[0030] In some embodiments, the cylinder block seat of the moving cylinder 7 is fixed to the bottom surface of the mounting plate 8 by bolts, and the output end of the moving cylinder is connected to the jaw cylinder 4 by bolts to ensure that the jaw cylinder 4 can be driven to move. The jaw cylinder 4 is a conventional rotating cylinder, and the output jaws at its output end can rotate. A clamping rod 5 is connected to the output jaws by screws. The clamping rod 5 penetrates to the bottom of the connecting main board 1, and the end of the clamping rod 5 is connected to the positioning clamping jaw 6 by bolts.

[0031] To ensure the rotation effect of the clamping rod 5, a bearing is provided at the contact between the clamping rod 5 and the connecting main board 1 to ensure the rotation effect of the clamping rod 5.

[0032] In some further embodiments, a connecting seat 9 is further provided between the connecting main board 1 and the mounting plate 8. The lifting cylinder can be connected to the connecting seat 9. When the lifting cylinder works, it drives the connecting seat to lift and lower, so as to drive the connecting main board 1 to lift and lower, thereby realizing that the positioning head at the end of the positioning rod 2 is inserted into the positioning hole of the steering knuckle.

[0033] As is known by common technical knowledge, the present invention can be implemented by other embodiments without departing from its spirit or essential features. Therefore, the above-disclosed embodiments are illustrative in all aspects and not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are encompassed by the present invention.
