Description

Technical Field

[0001] The utility model belongs to the technical field of engine parts detection, and particularly relates to a full-automatic high-precision digital comprehensive detection device for engine valves. Background Technique

[0002] The internal combustion engine valve is a key component of the automobile engine and is the central hub for completing power drive. The working temperature of the intake valve is in the range of 300°C - 400°C, and that of the exhaust valve is 600°C - 750°C. The working temperature of the exhaust valve of some diesel engines reaches about 850°C. It can be seen that the valve is in a high-temperature and strongly corrosive combustion gas, and at the same time, it has to bear the repeated actions of tensile, compressive, and impact forces. In such a harsh service environment, the valve must have good comprehensive mechanical properties. For the detection of the rod diameter, conical surface, disc end face, disc outer circle, and lock groove, the existing detection technology mainly relies on manual use of micrometers for detection, resulting in low detection efficiency. Content of the Utility Model

[0003] Aiming at the above problems, the purpose of the utility model is to provide a full-automatic high-precision digital comprehensive detection device for engine valves, which solves the problems of incomplete detection, inaccurate precision, and high labor cost of the traditional method of detecting valves by personnel.

[0004] To achieve the above purpose, the technical solution adopted by the utility model is: a full-automatic high-precision digital comprehensive detection device for engine valves, including a full-size detection station for valves. The full-size detection station for valves is composed of a valve driving component, a valve detection component, and a valve support component. The valve detection component includes a vertical frame, on which a linear module and a valve stem clamping seat are installed. An elevating frame is installed on the sliding seat in the linear module, and a Keyence TM-X5040 sensor is installed on the elevating frame. A disc outer circle runout sensor, a conical surface runout sensor, and a valve stem runout sensor are also installed on the vertical frame. The valve driving component is installed on one side of the valve detection component.

An installation frame is installed on the sliding seat on the guide rail, and the installation frame is connected to the push rod of the cylinder. A servo motor is installed on the installation frame and a rotating roller is rotatably installed. The servo motor is drivingly connected to the rotating roller.

[0006] In order to accurately measure the runout of the valve stem, the runout of the conical surface, and the runout of the disc outer circle;

[0007] As a further improvement of the above technical solution: the axes of the cone runout sensor and the valve stem runout sensor are parallel to the mounting plane of the stand, and the axis of the disk outer circle runout sensor is inclined.

[0013] As a further improvement of the above technical solution: the valve stem clamping seat includes two bearings installed opposite to each other on the left and right, and the rotating roller is located between the two bearings.

[0014] The beneficial effect of this improvement is that the rotating roller can move under the drive of the cylinder, and cooperate with the valve stem clamping seat to press the stem of the valve, thereby ensuring the stability of the valve clamping.

[0015] In order to ensure the stability of the valve stem clamping seat on the valve support;

[0016] As a further improvement of the above technical solution: the number of the valve stem clamping seats is two.

[0017] The beneficial effect of this improvement is that the two sets of valve stem clamping seats can cooperate with the rotating roller to achieve three-point support clamping of the valve.

[0018] In order to drive the valve to rotate stably;

[0019] As a further improvement of the above technical solution: a driving pulley is installed on the output shaft of the servo motor, a driven pulley is installed on the rotating shaft of the rotating roller, and a belt is connected between the driven pulley and the driving pulley.

A guide rail 62 and the cylinder block of a cylinder 64 are installed on the base 61. An installation frame 65 is installed on the sliding seat on the guide rail 62. The installation frame 65 is connected to the push rod of the cylinder 64. A servo motor 66 is installed on the installation frame 65 and a rotating roller 67 is rotatably installed. The servo motor 66 is drivingly connected to the rotating roller 67. The valve drive assembly 6 and the valve detection assembly 7 can firmly clamp valves of different specifications, and then accurately and automatically detect the full size of the valves through the multiple sensors provided, effectively reducing the detection cost, increasing the detection efficiency, and reducing the error rate. The axes of the conical surface runout sensor 76 and the valve stem runout sensor 77 are parallel to the installation plane of the vertical frame 71, and the axis of the disk outer circle runout sensor 75 is inclined. The valve stem runout sensor 77, the disk outer circle runout sensor 75, and the conical surface runout sensor 76 can respectively accurately detect the runout of the valve stem, the conical surface, and the disk outer circle. The Keyence TM-X5040 sensor 74 is relatively arranged on the left and right sides of the valve stem runout sensor 77. The conical surface runout sensor 76 can stably move up and down under the drive of the linear module 72, and then detect the overall size of the valve. The valve stem clamping seat 78 includes two bearings installed opposite to each other left and right. The rotating roller 67 is located between the two bearings. The rotating roller 67 can move under the drive of the cylinder 64, and cooperate with the valve stem clamping seat 78 to press the valve stem, ensuring the stability of valve clamping. The number of valve stem clamping seats 78 is two, and the two groups of valve stem clamping seats 78 can cooperate with the rotating roller 67 to achieve three-point support clamping of the valve. A driving pulley is installed on the output shaft of the servo motor 66, a driven pulley is installed on the rotating shaft of the rotating roller 67, and a belt is drivingly connected between the driven pulley and the driving pulley. The servo motor 66 can drive the rotating roller 67 to rotate stably through the belt drive mechanism.

A valve loading mechanism 1 and a valve full laser printer station 4 are respectively installed on both sides of the valve handling mechanism 2. A valve storage mechanism 5 is installed on one side of the valve full laser printer station 4. The valve handling mechanism 2 can grab valves.The automatic detection of valves is realized by using the valve feeding mechanism 1, the valve full laser printer station 4, and the valve storage mechanism 5.

[0033] In this embodiment, the model of the Keyence TM-X5040 sensor 74 is: TM-X5040.

[0034] The working principle of this technical solution is as follows: In this device, the outer disk runout sensor 75, the conical surface runout sensor 76, and the valve stem runout sensor 77 are all displacement sensors; the valve on the valve feeding mechanism 1 by the valve handling mechanism 2 makes the stem of the valve located on one side of the valve stem clamping seat 78, and then the cylinder 64 extends to drive the slide 63 to move, so that the rotating roller 67 presses against the other side of the valve stem, and then the servo motor 66 runs to drive the rotating roller 67 to rotate through the belt drive mechanism, thereby making the valve stem rotate. At this time, the outer disk runout sensor 75, the conical surface runout sensor 76, and the valve stem runout sensor 77 detect the runout of the valve stem. At the same time, the motor in the linear module 72 runs to drive the lifting frame 73 to move linearly, thereby driving the Keyence TM-X5040 sensor 74 to move along the axial direction of the valve stem to detect the full size of the valve stem by laser measurement. After the detection is completed, the valve handling mechanism 2 transports the detected valves to the valve full laser printer station 4 and the valve storage mechanism 5 in sequence for marking and temporary storage processing.
