Meter pointer assembling device

Abstract

The invention relates to a meter pointer assembling device, comprising a base, a pointer pressure head, a pointer pressing cylinder and a driving mechanism as well as a pointer guide plate used for fixing a meter, wherein the pointer pressure head is arranged on the pointer pressing cylinder, the pointer pressing cylinder is connected with a driving mechanism, the base is provided with a pointer guide plate mounting column, one side of the pointer guide plate is hinged with the pointer guide plate mounting column, the meter is arranged on the bottom surface of the pointer guide plate, a pointer guide hole used for placing a pointer is formed on the pointer guide plate, and the pointer guide plate can turn over around a hinge axis. The meter pointer assembling device disclosed by the invention has reasonable structural design, convenience in use and speediness, the driving mechanism drives the pointer pressing cylinder to drive the pointer pressure head to move above the pointer guide plate and sequentially presses the pointer placed on the meter downward into a motor shaft of the meter, stress is uniform when the pointer is pressed into the motor shaft, universalization of a tool is realized to the utmost extent, utilization rate of the tool is improved, investment cost of the tool is saved, and production period is shortened.

Description

technical field [0001] The invention relates to an assembly device, in particular to an instrument pointer assembly device. Background technique [0002] Instrument pointers are widely used in vehicles such as automobiles, ships or trains, and the instrument pointers are installed on the motor shaft. [0003] In the prior art, there are mainly two assembly methods for instrument pointers: one is to use an air press to cooperate with tooling to install the pointer, and the odometer, tachometer, water temperature gauge, fuel gauge and other instrument pointers are assembled synchronously. It is composed of lower template, guide mechanism, pointer suction head and other mechanisms. When working, the instrument is positioned on the lower template, and the pointer is adsorbed and positioned on the vacuum needle suction head. Installed on the pointer motor shaft of the instrument, but because the position of the gauge and the size of the pointer are different, the production tool...

[0003] In the prior art, there are mainly two assembly methods for instrument pointers: one is to use an air press to cooperate with tooling to install the pointer, and the odometer, tachometer, water temperature gauge, fuel gauge and other instrument pointers are assembled synchronously. It is composed of lower template, guide mechanism, pointer suction head and other mechanisms. When working, the instrument is positioned on the lower template, and the pointer is adsorbed and positioned on the vacuum needle suction head. Installed on the pointer motor shaft of the instrument, but because the position of the gauge and the size of the pointer are different, the production tooling can only be adapted to a specific model, which is a special tooling and cannot be universalized, so the investment cost of the tooling is high. Especially for small batch products, the cost increase is very large; the other is that the pointers of the odometer, tachometer, water temperature gauge and fuel gauge are all pressed by a separate cylinder, and the pointer is installed on the cylinder to position the pressure head to ensure the assembly of the pointer. Direction, the cylinder is fixed on the reversible upper template, when working, position the instrument on the lower template, and cover the reversible upper template, at this time, the centerline of all the pointer shaft holes basically coincides with the shaft centerline of the motor , the cylinder drives the pointer to assemble the pointer to the motor shaft, but also due to the gauge position of the instrument, the size of the pointer is different, the number of cylinders is large, the cost is high, and the time pressure for tooling is also long, resulting in a long production cycle and not conducive to life.
