Specific embodiment
The present invention is described in further detail in the following with reference to the drawings and specific embodiments.
As shown in Figure 1, a kind of linear bearing linearity measurer based on pressure change, including shell 1, measuring rod 2,
Thrust spring 3, pressure detecting element 4, briquetting 5 and signal processor；Measuring rod mounting hole 6 is offered in the shell 1, is surveyed
Gauge rod mounting hole 6 is blind hole structure, and the measuring rod 2 is installed in measuring rod mounting hole 6, and measuring rod 2 is in measuring rod mounting hole 6
It is interior that there is linear movement freedom degree；The pressure detecting element 4 is packed in the bottom hole of measuring rod mounting hole 6, the thrust spring 3
One end is connected to the tail end of measuring rod 2, and 3 other end of thrust spring is connected on briquetting 5, and briquetting 5 abuts against contact in pressure detecting
On element 4, signal output end and the signal processor of pressure detecting element 4 are electrically connected；In the body of rod table of the measuring rod 2
Face offers linear movement guide groove 7, and linear movement guide groove 7 is parallel with measuring rod 2；It is fixedly mounted on the shell 1 limited
Position guide pin 8,8 end of limition orientation pin extend in linear movement guide groove 7, pass through limition orientation pin 8 and straight line
Mobile guide groove 7 cooperates, and is defined to the revolution freedom degree of measuring rod 2, and carries out to the linear movement range of measuring rod 2
It limits.
The pressure detecting element 4 uses piezoelectric pressure indicator or resistance strain type pressure sensor.
Illustrate first use process of the invention with reference to the accompanying drawing:
Firstly, shell 1 and the bearing block of linear bearing are fixed together, guarantee that the tip of measuring rod 2 vertically acts against
On the guide rail of linear bearing, while ensuring that thrust spring 7 has certain decrement.
Next, moving the bearing block of linear bearing along guide rail, measuring rod 2 can be with the mobile synchronous production of bearing block
The variation of raw axial position, in the process, the decrement of thrust spring 3 also will change, and then lead to thrust spring 3
Spring force changes, and the spring-force driven dual changed will directly be applied to pressure detecting member after briquetting 5 in the form of pressure
On part 4, the pressure transmitted at this time by 4 automatic measurement briquetting 5 of pressure detecting element, and measured by pressure detecting element 4
To pressure data will be transmitted directly in signal processor, signal processor can be analyzed and processed pressure data, and same
Step is converted into straightness data.
The scope of patent protection that scheme in embodiment is not intended to limit the invention, it is all without departing from carried out by the present invention etc.
Effect implements or change, is both contained in the scope of the patents of this case.
