1、 Construction and Function

The coercion device for the rolling linear guide pair is composed of the coercion device main body, driving components, coercion organization, etc. It is a high-performance functional component used in conjunction with the rolling linear guide pair. The normally open type has the functions of fixed workbench, precise positioning, avoiding oscillation, and improving stiffness; The normally closed type also has the effect of power-off and emergency braking.

2、 Terminology Explanation

1. Normally open type: When no air or oil pressure is supplied, the pressure tissue of the pressure sensor is in a state of release.

2. Normally closed type: When there is no air or oil pressure supplied, the coercing tissue of the coercer uses the force of a tension spring or screw to coerce the linear guide rail.

3. Persistence: The effect is on the motion direction and vertical load of the linear guide rail pair.

The persistence varies depending on the static friction coefficient between the guide rail and the stressed tissue. (The persistence force in this product sample is the calculated value when the static friction coefficient is 0.1.)

4. Minimum operating pressure: The minimum pressure required for the normal operation of the coercion device.

5. Maximum operating pressure: The maximum pressure allowed during normal operation of the coercion device.

6. Maximum remaining pressure: The maximum remaining pressure allowed after the oil pressure regulator stops supplying oil.

7. Device pad: A pad that aligns the height of the coercion device with the height of the rolling linear guide rail pair.

8. Air consumption: The amount of air required for one stroke of the coercion device.

9. Hydraulic oil consumption: The amount of oil required for one stroke of the actuator action.

10. Reaction time:

Normally open duress response time: After the system announces the signal of starting gas and oil supply, it reaches the moment of starting gas and oil supply to the duress.

Normally closed duress response time: When the system announces a signal to stop gas and oil supply, it reaches the moment when gas and oil supply to the duress are stopped.

11. Echoing moment:

The response time of the normally open coercion device: from the beginning of supplying air and oil to the coercion device, to the moment of clamping the linear guide rail.

The response time of the normally closed coercion device: from the moment when the gas supply and oil supply to the coercion device are stopped to the moment when the linear guide rail is clamped.

3、 Type

1. Pneumatic Normally Open Series

1) Features

a. Through the principle of wedge block expansion, pressure is applied to complete the stress.

b. Compact construction with strong persistence.

c. Innovative planning to avoid rigid impact during clamping.

d. The device is convenient and directly connected to the workbench, without the need to change the scale of the workbench.

e. Precision positioning, suitable for pneumatic clamping of moving shafts.

Note: The pressure corresponding to the force in the table is 0.6MPa; Persistence is proportional to pressure within the range of applied pressure.

2. Air pressure normally closed with brake series

1) Features

a. Use tension spring energy storage effect on wedge-shaped blocks to complete coercion and braking.

b. Use air pressure to relieve stress.

c. Quick response, avoiding vertical axis falling and collision, achieving the effect of maintaining the machine tool.

d. The device is convenient and directly connected to the workbench, without the need to change the scale of the workbench.
