[0002] A camshaft is a component in a piston engine. Its function is to control the opening and closing actions of the valves. Although in a four-stroke engine the rotational speed of the camshaft is half that of the crankshaft (in a two-stroke engine the rotational speed of the camshaft is the same as that of the crankshaft), generally its rotational speed is still very high and it needs to withstand a large torque. Therefore, in the design, the requirements for the strength and support of the camshaft are very high, and its material is generally high-quality alloy steel or alloy steel. Since the valve motion law is related to the power and operating characteristics of an engine, the camshaft design occupies a very important position in the engine design process.

However, the existing rotating seat for camshaft processing has the following defects: The camshaft is clamped and fixed by a single clamping mechanism, resulting in poor stability during the rotating processing; and it cannot clamp and fix camshafts of different lengths, cannot meet the usage requirements, resulting in limited processing and poor applicability. Summary of the Utility Model

[0009] As a further improvement of the present utility model, a plurality of sliders are fixedly connected to the bottom of the sliding seat, and a sliding groove for the sliders to slide is provided on the base.

[0010] The beneficial effects of the present utility model: The present utility model clamps and fixes the camshaft through two sets of clamping mechanisms, improving the stability during the rotary machining of the camshaft; at the same time, the position of the sliding seat can be adjusted by the drive of the second motor, so that camshafts of different lengths can be clamped and fixed, with strong applicability.

One end of the rotating rod 5 is fixedly connected to a fixed seat 6, a plurality of first telescopic rods 7 are fixedly connected to the outside of the fixed seat 6, and the movable shaft of the first telescopic rod 7 passes through the side wall of the fixed seat 6 and is fixedly connected to a first clamping plate 8.

[0021] A second motor 9 is fixedly connected to the base 1, a lead screw 10 is provided at the output end of the second motor 9, and a bearing seat 17 rotatably connected to the lead screw 10 is fixedly connected to the base 1, which improves the stability of the lead screw 10 during rotation. A sliding seat 11 is threadedly connected to the lead screw 10. The surface of the lead screw 10 is provided with an external thread. The sliding seat 11 is provided with a threaded through groove for the lead screw 10 to pass through, and an internal thread matching the external thread is provided at the position of the threaded through groove inside the sliding seat 11. A plurality of sliders 18 are fixedly connected to the bottom of the sliding seat 11, and a sliding groove 19 for the sliders 18 to slide is provided on the base 1. When the lead screw 10 rotates, the sliding seat 11 will slide stably. A bearing member 12 is provided above the sliding seat 11. A connecting seat 13 fixedly connected to the outer ring of the bearing member 12 is provided on the sliding seat 11.

[0022] Working principle: When the present utility model is specifically implemented, first, one end of the camshaft is installed in the fixed seat 6, the movable shaft of the first telescopic rod 7 is controlled to extend, so that the first clamping plate 8 clamps and fixes one end of the camshaft. Then, the second motor 9 is controlled to start, driving the screw rod 10 to rotate. The rotation of the screw rod 10 causes the sliding seat 11 to slide to one side. The sliding of the sliding seat 11 drives the bearing member 12 to move through the connecting seat 13, so that the bearing member 12 moves to the outside of the other end of the camshaft. At this time, the other end of the camshaft is located between multiple second clamping plates 15 inside the bearing member 12. At this time, the movable shaft of the second motor 9 is controlled to extend, so that the second clamping plates 15 clamp and fix the other end of the camshaft. Thus, the camshaft is clamped and fixed by two groups of clamping components, improving the stability of the camshaft during subsequent rotational processing, and can clamp and fix camshafts of different lengths, with strong applicability. Finally, by controlling the first motor 4 to start, driving the rotating rod 5 to rotate, the rotation of the rotating rod 5 drives the camshaft to rotate through the fixed seat 6, thereby facilitating multi-angle processing of it.
