Abstract

This invention relates to one magnetic socket device, which comprises socket, supportive bar and micro adjuster and is characterized by the following: the micro adjust probe is set on beam with two parts fixed on one slide cover with each one covered on supportive bar top end and two down end fixed on one socket; the base socket is composed of seat, spiral coil, aluminum coils skeleton and connection screw nail; the spiral coil is around aluminum skeleton on the skeleton chamber fixed by connection nail with two ends connected to wire through wire hole and power.

Description

technical field [0001] The invention relates to a magnetic watch stand device. Background technique [0002] The magnetic base device refers to the support for clamping measuring instruments such as thousand (hundred) indicators, lever thousand (hundred) indicators, etc., and can also be used as a probe clamping support for micro-displacement measuring instruments. It uses the controllable magnetic force of the base to firmly absorb on the plane of other iron objects for work. The magnetic force comes from the magnetic field source generated by the permanent magnet in the base. The magnetic table base device is easy to operate and easy to use, and is suitable for measurement in various occasions. It is widely used to measure the shape error and position error of the workpiece, and can measure the accurate value easily and quickly. [0003] The existing magnetic table base device is shown in FIG. 1 , which includes a base 1 , a support rod 2 , a suspension rod, and a fine-...

AI Technical Summary

Problems solved by technology

The adsorption force of each magnetic watch base is determined by its internal permanent magnet, so the existing magnetic watch base has an unadjustable adsorption force and cannot meet various needs for adsorption capacity.

In addition, the base and the support rod are connected by a movable connection device, and the support rod is not fixed stably, which is prone to shaking and affects the measurement accuracy

[0007] 2. The existing magnetic base has insufficient ability to resist external interference

The volume and weight of the object to be measured are generally relatively large, and most of them are rigidly transmitted. Therefore, when the base 1 and the object to be measured are vibrated by external interference at the same time, their ability to transmit vibration is not the same, and then the measuring instrument or the probe. Vibration is greatly amplified relative to the measured object, which greatly affects the accuracy of measurement, and due to the influence of vibration, the measured value cannot be quickly stabilized, causing inconvenience in data collection

[0008] 3. The adjustment of the existing fine-tuning head 3 is inconvenient, and after each adjustment, due to the mechanical deformation of the fine-tuning head 3 and the vibration at the top of the cantilever beam, it is difficult to quickly stabilize the value of the measuring instrument, and even cause the measured value to slow down. drift

Measuring instruments or probes are clamped at the fine-tuning head 3, and each adjustment is always realized by tightening the screws. Since the fine-tuning head 3 is elastic, the fine-tuning head 3 always deforms slowly after adjustment, and it takes a long time to stabilize. It is inconvenient to operate and affects the measurement

However, due to the need to tighten the screws during adjustment, a large force acts on the top of the cantilever beam, causing the cantilever beam to vibrate, which also affects the accuracy of the measurement.
