Problems solved by technology

General pressure pointer assembly equipment has the following shortcomings: 1. The U-shaped line unit is not equipped with a pointer material box; Can not return to the zero position of the dial; 3. After the pointer is press-fitted, the instrument cannot self-check and can only be detected manually; 4. Manually press the pointer into the needle shaft of the stepping motor, which is inefficient and easy to cause the pointer after press-fitting inaccurate instructions

Abstract

The invention discloses a pointer pressing device for a stepping motor combined instrument, and belongs to the technical field of automobile instrument pointer pressing equipment. Mainly, the pointer pressing device for the stepping motor combined instrument is high in pressing speed and precision and capable of being suitable for large-batch production. The pointer pressing device is mainly characterized by being composed of a power source, a PLC, a pneumatic control unit module, an upper clamp die, a lower clamp die, a pointer tray, an industrial personal computer, a display, a voltage source, a resistance signal, a CAN signal and a cable; a pressing pointer clamp is formed by the upper clamp die and the lower clamp die; the liquid crystal display is connected with the industrial personal computer through a serial port; the clamp is connected with the industrial personal computer through a flexible flat cable; the power source, the PLC, the pneumatic control unit module, the voltage source, the resistance signal and the CAN signal are connected to a host; and an electric cabinet is connected with the industrial personal computer. For the pressing characteristic of a pointer of the stepping motor combined instrument, the pointer pressing device is mainly used for pressing the pointer of the stepping motor.

Description

technical field [0001] The utility model belongs to the technical field of press-fitting equipment for automobile instrument pointers. It specifically relates to a method in which the pointer press fitting of a combination instrument with a stepping motor is driven by a servo motor. The pressing force can be monitored and controlled, and it can display the pressure process curve and automatically judge the qualified range of the pressure value. The pressure has an alarm function to ensure that the zero state of the pointer is consistent with the zero line of each small meter. Background technique [0002] The assembly of the previous moving magnet combination instrument is cumbersome, and the indication accuracy is not high, the scrap rate is high, and the operator's skills are high. With the development and progress of electronic technology, the requirements for the intelligence and monitorability of the whole vehicle are getting higher and higher, and the appearance of th...
