Description

A measuring head device for a button life testing machine

technical field

The utility model relates to a measuring head device, in particular to a measuring head device used for a button life testing machine.

Background technique

For electronic products, such as mobile phones, laptops and keyboards, semi-finished or finished keys must be tested during the manufacturing process to determine their service life. During the test, a button life testing machine is usually used to drive the measuring head device to reciprocate, simulating the pressing of human hands.

However, the probe devices currently on the market have the disadvantages of large impact error, easy loosening and large friction, which will bring certain errors in the key life test and make the test results inaccurate.

Utility model content

In order to solve the deficiencies of the prior art, the purpose of this utility model is to overcome the defects of the prior art, and provide a measuring head device for a button life testing machine with less hitting error, less looseness and less friction.

In order to achieve the above object, the utility model adopts the following technical solutions:

A measuring head device for a button life testing machine, comprising a striking rod, a bearing and a striking head, the striking rod is covered with a bearing, one end of the bearing is connected with a guide sleeve which is also set on the striking rod, and the other end of the guiding sleeve is One end is provided with a weight, and the weight is fixed on the striking rod, and the outer end of the weight is provided with a bolt fixed on the striking rod; the other end of the striking rod is fixed with a striking head.

Further, the striking head is made of rubber.

Further, a lubricating material is provided at the contact surface between the bearing and the guide sleeve.

Further, a groove is provided on the end where the bearing is connected to the guide sleeve.

Further, the lubricating material is graphite or copper gasket.

The beneficial effects of the utility model are as follows: the utility model is suitable for the measuring head device of the key life testing machine, and the test of the key life is realized by matching the groove on the bearing with the main body of the testing machine, and the installation is very convenient; at the same time, the weight The pressing force and friction of the beating head can be adjusted on the beating rod, which can better fix the device on the main body of the testing machine, so the beating error will be significantly reduced, so it is suitable for promotion.
