Description

Technical Field

[0001] This invention relates to the field of camshaft inspection, and more particularly to a multi-station camshaft groove width inspection device. Background Technology

[0002] The camshaft is the core component of the valve train in an internal combustion engine. It is cylindrical in shape and has multiple cams with different profiles distributed on its surface. It is driven to rotate by the crankshaft through timing gears, chains, or belts. The eccentric profile of the cams pushes the valve tappets, pushrods, and other components to precisely control the opening and closing timing, sequence, and stroke of the intake and exhaust valves. This ensures that the combustible mixture can enter the cylinder in a timely manner and that exhaust gases can be fully discharged under different operating conditions, directly affecting the engine's power, fuel consumption, and emissions performance.

[0003] When a camshaft needs to be inspected, the operator places the camshaft in the clamping mechanism on the inspection device, and then the inspection mechanism inspects the groove width of the camshaft to be inspected. However, in the existing technology, the operator has to place the camshaft one by one in the clamping mechanism, and then the inspection mechanism inspects it. Finally, the inspected camshaft is manually removed. This process is repeated, which is time-consuming and labor-intensive, increasing manpower and time costs, and making it impossible to achieve the problem of low efficiency in the inspection of large batches of camshafts.

[0033] Working Principle: This camshaft inspection device uses the support base 20 as its installation foundation. Through the coordinated operation of the rotary inspection mechanism 10, the feeding mechanism 30, the inspection mechanism 40, the unloading mechanism 50, and the clamping mechanism 60, a complete inspection process and three functional stations are formed, effectively saving inspection time and labor costs. The workpiece to be inspected is the camshaft 70. The rotary inspection mechanism 10 is the core of the device's operation. Its fixed circular plate 11 provides rotation space and support for the rotating table 12. The drive component 13 in the drive assembly is a motor. The drive shaft passes through the fixed circular plate 11 and the inner wall of the rotating table 12, and is securely connected by the fixing ring 14 on the outside of the drive end. When the drive component 13 operates, it can drive the rotating table 12 relative to the fixed plate 11. The rotating plate 11 provides the power basis for the orderly coordination of various mechanisms. The feeding mechanism 30 is responsible for the automatic and orderly feeding of workpieces. The fixed seat 31 is fixed to the top of the support base 20. The output shaft box 32 is the area for placing the workpiece to be tested and is located outside the fixed seat 31. The elastic element 33 is a spring, with both ends passing through the output shaft box 32 and the outside of the fixed seat 31 to achieve a detachable connection. The loading plate 38 inside the output shaft box 32 can be operated by the top handle 36 to complete the workpiece loading. Under the elastic force of the elastic element 33, the workpiece is guided by the output shaft groove 34 and the bottom guide plate 35, and pushed by the telescopic push plate 37 to the output shaft groove 34, and then accurately falls onto the clamping mechanism 60 on the rotating table 12. The clamping mechanism 60 is the core bearing and fixing area of ​​the workpiece. It consists of a clamping assembly and a spring clamping assembly. In the clamping assembly, the fixed seat 61 is detachably installed by the top bolt 62. Two sliding plates 64 are provided in the inner wall slide groove 63. The double-headed cylinder 68 drives the two sliding plates 64 to extend and retract synchronously along the slide groove 63 to complete the clamping or releasing action. The spring clamping assembly is equipped with a clamping plate 67 by the fixed block 65 on the top of the sliding plate 64. The elastic element 66 between the clamping plate 67 and the fixed block 65 is a spring, which can adapt to the size of the camshaft 70 to provide elastic clamping force for the clamping plate 67, ensuring that workpieces of different thicknesses can be stably clamped. After the workpiece is fixed by the clamping mechanism 60, the rotating table 12 drives the workpiece to the position of the detection mechanism 40. The fixed seat 41 of the detection mechanism 40 is located on the top of the support base 20. The detector 42 is an existing groove width detection device that is connected to the fixed seat 41 through a rotating bolt 43. The position of the detector 42 can be rotated and adjusted to accurately correspond to the workpiece, thus completing the groove width detection operation. After the detection is completed, the rotating table 12 transfers the workpiece to the unloading mechanism 50. The rotating shaft 51 of the unloading component is fixed to the top of the support base 20. The cylinder 54 on the drive end connecting plate 53 drives the lifting plate 55 to adjust its height. The two telescopic rods 56 on the inner wall of the lifting plate 55 drive the clamping plate 57 to clamp the workpiece. Then, the workpiece is transferred by the rotating shaft 51 to the material box 52 next to the support base 20 and released, completing the unloading operation and facilitating subsequent material retrieval by the operator.
