Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automotive part production, and particularly relates to a clamping fixture for preventing misoperation in the closing sequence. Background Art
[0002] Automotive parts, as the foundation of the automotive industry, are essential factors for the sustainable and healthy development of the automotive industry. Especially in the current automotive industry, with the vigorous and booming independent development and innovation, a strong parts system is needed as support.
[0003] For example, the sheet metal parts of automotive parts are the core components of the vehicle. In the suspension welding operation of sheet metal parts of automotive parts, the clamping sequence of the sheet metal parts of automotive parts is usually ensured by the operator's action memory. Therefore, the requirements for the operator's operation are relatively high, and the operator needs to be very familiar with the clamping and suspension welding process of the sheet metal parts of automotive parts, so as to ensure the clamping and welding quality of the sheet metal parts of automotive parts through the method of assigning specific personnel to specific positions.
[0004] However, in actual situations, the operator is prone to fatigue. Once the operator is in a state of fatigue, it is easy for the operator to make mistakes in the clamping sequence of the sheet metal parts of automotive parts, resulting in a decrease in the clamping and welding quality of the sheet metal parts of automotive parts, thereby causing greater cost losses. Summary of the Utility Model
[0005] The utility model aims to provide a clamping fixture for preventing misoperation in the closing sequence, which can prompt the operator to make mistakes in the clamping sequence of the sheet metal parts of automotive parts.
[0006] To achieve the above object, each aspect of the present application can be implemented in one or more of the following embodiments:
[0007] 1) A clamping fixture for preventing misoperation in the closing sequence, comprising a base. Along the length direction of the upper surface of the base, a first clamping mechanism, a second clamping mechanism, and a third clamping mechanism are sequentially provided. A first control switch corresponding to the position of the first clamping mechanism, a second control switch corresponding to the position of the second clamping mechanism, and a third control switch corresponding to the position of the third clamping mechanism are provided on the upper surface of the base.
[0008] The clamping fixture further comprises a microprocessor. The input end of the microprocessor is electrically connected to the first control switch, the second control switch, and the third control switch in sequence. The output end of the microprocessor is electrically connected to the first clamping mechanism, the second clamping mechanism, and the third clamping mechanism in sequence, and the first clamping mechanism, the second clamping mechanism, and the third clamping mechanism are sequentially started according to the starting sequence of the first control switch, the second control switch, and the third control switch.
[0009] The present utility model designs a first clamping mechanism, a second clamping mechanism and a third clamping mechanism for clamping and welding different positions of the sheet metal parts of automotive components; during the operation of the operator, the operator first activates the first control switch, and the first control switch sends a start signal into the microprocessor. After the microprocessor determines that the start signal is from the first control switch, it issues an instruction to activate the first clamping mechanism. Conversely, if the first clamping mechanism is not activated, the operator can determine that an operation error has occurred.
[0010] Similarly, when the operator activates the second control switch, the second control switch sends a start signal into the microprocessor. After the microprocessor determines that the start signal is from the second control switch, it issues an instruction to activate the second clamping mechanism. Conversely, if the second clamping mechanism is not activated, the operator can determine that an operation error has occurred.
[0011] Similarly, when the operator activates the third control switch, the third control switch sends a start signal into the microprocessor. After the microprocessor determines that the start signal is from the third control switch, it issues an instruction to activate the third clamping mechanism.

After completing the clamping and welding of the sheet metal parts of automotive components, under the action of the first telescopic cylinders, the two first sliding blocks move away from each other along the length direction, thereby releasing the sheet metal parts of automotive components.
