Description

Technical Field

[0001] The utility model belongs to the technical field of camshaft processing, and particularly relates to a camshaft through-hole drilling device. Background Art

[0002] The camshaft is a component in piston engines. Its function is to control the opening and closing of the valves. Although the camshaft speed in a four-stroke engine is half that of the crankshaft, or the same speed as the crankshaft in a two-stroke engine, it is still generally very high and must withstand significant torque. Therefore, the design of the camshaft requires high strength and support, and it is generally made of high-quality alloy steel or alloy steel. Because the movement of the valves is closely related to the power and operating characteristics of an engine, camshaft design plays a crucial role in the engine design process.

[0003] During the camshaft processing, it is necessary to drill through holes in the camshaft, and the hole sizes at both ends are inconsistent. When drilling holes at both ends of the camshaft, the camshaft is generally fixed on the drilling platform manually with a clamp, and then one end of the camshaft is drilled by moving the drill bit. After drilling, the clamp is loosened, the camshaft is reversed, and then fixed with the clamp, and the other end is drilled. The above processing method requires multiple clamping and positioning, and the concentricity of the processed product is low. In addition, there are many processing steps, the operation is cumbersome, and the work efficiency is low, which makes it difficult to meet the needs of actual production and processing. For this purpose, an improved camshaft through-hole drilling device is designed. Utility Model Content

Specifically, the second motor drives the screw to rotate, and the screw nut on the screw moves horizontally. The screw nut is connected to the base plate through the connecting head, driving the base plate to move along the slide rail.

[0015] Furthermore, two slag crushing grooves are provided on the left and right sides of the fixture on the processing table, a fence is provided on the periphery of the fixture on the processing table, and a collection box is provided under the processing table.

[0016] By adopting the above-mentioned structural design, a slag trough is opened on the processing table, and a collection box is set under the slag trough, which can collect the debris generated during the drilling process.
