[0038] The semi-automatic assembly and detection device to which the present invention is applied is a special process equipment for assembly and straightening processing. The present invention is used for the electrical component control of the device to meet the process and detection function requirements. The process flow chart of the operation of the semi-automatic assembly and detection device is as follows: Figure 5 shown.

[0039] The electrical components of the semi-automatic assembly and inspection device include cylinder 1, motor 4, cylinder 2, cylinder 3 and electric cylinder 5 (electric actuator). The above electrical components are manually controlled to produce corresponding actions according to the process requirements, thereby completing the process flow of inspection-straightening-inspection, and finally adjusting the straightness of the workpiece, and inspecting the workpiece that meets the design requirements. While satisfying the logical relationship of mutual control, each component remains relatively independent, and independent control of each component can be achieved. Among them:

[0040] Cylinder No. Ⅰ is used to measure and position the workpiece to ensure that the workpiece will not produce axial and radial movement. Its control circuit is called a measurement and clamping control circuit.

[0041] The motor 4 is used to drive the workpiece to rotate, thereby completing the rotation measurement and detecting the radial runout of the workpiece. Its control circuit is called a drive motor control circuit.

[0042] Cylinder No. Ⅱ 2 and cylinder No. Ⅲ 3 are used to clamp the workpiece to facilitate straightness adjustment of the workpiece. The two cylinder air circuits are connected in series and act synchronously to achieve multi-level force clamping of the workpiece to avoid springback during the straightening process. The control circuit is called a straightening and clamping control circuit.

[0043] The electric cylinder 5 is used to adjust the straightness of the workpiece. The extension length of the cylinder rod is manually controlled according to the needs. After the straightening is completed, it can be reset with one button to return to the initial zero position. Its control circuit is called a straightening control circuit.

[0044] The specific working process of the present invention is:

[0045] First start the measurement and compression control circuit. Figure 1 Upper switch K3 of switch 12 in the middle III 上 Close, trigger relay J3, normally open contacts J31, J32, J33 are energized, solenoid valve No. Ⅱ is energized, which controls cylinder No. Ⅰ to extend, press the workpiece, and meet the conditions for rotation;

[0046] Then start the drive motor control circuit, Figure 2 The start end of the middle IV switch 13 is closed, and the motor 4 drives the workpiece to rotate to complete the detection process. Figure 3 The J1 and J2 relays remain disconnected to prevent the straightening and clamping control circuit from starting;

[0047] After the measurement is completed, the workpiece is stopped in the state where it needs to be straightened, and the drive motor control circuit is stopped. Figure 2 The stop terminal of the middle switch 13 is closed, and the straightening and clamping control circuit is started. Figure 3 Upper switch K2 of switch 11 in the middle II 上Closed, triggering the normally open contact of relay J1 to close, and the normally closed contact to disconnect, solenoid valve No. Ⅰ controls cylinder No. Ⅱ 2 and cylinder No. Ⅲ 3 to extend, clamping the workpiece, at the same time, relay J3 remains closed, cylinder No. Ⅰ 1 will not reset, normally closed contact J13 disconnects, and motor 4 will not operate erroneously;

[0048] Start the straightening control circuit, the lower end of switch 10 No. I is closed, the electric cylinder 5 is extended, and the workpiece is straightened. The downward pressure is manually controlled. During the straightening process, the relay J1 remains closed, and the cylinders 2 No. II and 3 No. III remain extended to clamp the workpiece. After straightening, the upper end of switch 10 No. I is closed, and the electric cylinder 5 is reset;

[0049] at last, Figure 3 Lower switch K2 of switch 11 in the middle II 下 Close, relay J2 is energized, normally closed contact J20 is disconnected, relay J1 is de-energized, cylinder 2 No. Ⅱ and cylinder 3 No. Ⅲ are reset, and the state returns to the measurement state. The workpiece is measured again. If the test is qualified, the operation is completed. If it is unqualified, the above process is repeated again until the test is qualified.

[0050] The present invention provides a control circuit that can meet the needs of semi-automatic assembly and detection equipment, can meet the control needs of step-by-step process equipment, and realize the cyclic control function of detection-straightening-detection; each sub-circuit circulates independently to complete independent control of the corresponding action unit. At the same time, each sub-circuit has an interlocking function, which can prevent damage to the workpiece in the event of misoperation, and can better meet the needs of scientific research-oriented tasks.

[0051] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0052] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.
