Abstract

The utility model discloses a kind of linear displacement transducer, including shell, sensor body and limiting device；The shell two sides offer a limiting slot, limiting slot is located at interior of shell, the limiting slot is arranged in parallel close to the part of shell upper with shell side, the setting at an acute angle of the top half of another part and shell side, and the limiting slot that two parts are constituted is integral connection；The part contacted on the limiting device with shell is additionally provided with a groove.Also linear displacement transducer can be kept in error range by simply adjusting for complex situations, and fixed effect is more preferable.

Description

A kind of linear displacement transducer

Technical field

The utility model relates to sensor fields, and in particular to a kind of linear displacement transducer.

Background technique

The parallelism error range that linear displacement transducer allows when in use is positive and negative 0.5mm, and angle is positive and negative 12 °, In most cases, the linear displacement transducer of the prior art is just able to satisfy demand；But it is directed to when being used under particular surroundings just It is not easy to very much adjust, complex conditions, such as operation cannot be well adapted to using linear displacement transducer in the prior art There are impurity or out-of-flatnesses for platform, and being mounted directly use in this case will cause measurement error.

Utility model content

The purpose of this utility model is to provide a kind of linear displacement transducers, also can be by simply adjusting for complex situations In error range, and fixed effect is more preferable for whole holding linear displacement transducer.

For this purpose, the utility model discloses a kind of linear displacement transducer, including shell, sensor body and limit dress It sets；The shell two sides offer a limiting slot, and limiting slot is located at interior of shell, and the limiting slot is close to the part of shell upper It is arranged in parallel with shell side, the setting at an acute angle of the top half of another part and shell side, and the limit that two parts are constituted Slot is integral connection；The part contacted on the limiting device with shell is additionally provided with a groove.

In the utility model, the length of groove is slightly larger than the width of the shell, can be complete when guaranteeing that shell and groove contact It is stuck in groove entirely without left and right displacement.

In the utility model, the limiting device bottom is additionally provided with an arcuate surface, and the length of the arcuate surface is greater than outer The width of shell and be less than limiting device length.

The purpose that arcuate surface is arranged is to reduce the contact surface of shell and limiting device and support platform, avoid as far as possible The depth of parallelism and angle as caused by the out-of-flatness bring inclination of support platform it is not up to standard.

In the utility model, the bottom of the shell is provided with a convex body, the groove on the convex body and limiting device Match.

Wherein, the groove on the width and limiting device of convex body, which is set as groove, can just block convex body.

In the utility model, the intermediate position being arranged in the limiting slot of two sides is provided with a fixed stop.

Under normal conditions, it fixes a linear displacement transducer and needs two limiting devices, fixed stop main function is The position of limiting device is limited in both ends, and middle section is blocked by block, when preventing from being packed into two pieces of limiting devices simultaneously The nipped danger of hand.

In the utility model, the width of limiting device is the 1/4 ~ 1/2 of outer cover length.

As long as the width of limiting device is enough, due to the design of the limiting slot of the utility model, it is only necessary to one piece of limiting device Just linear displacement transducer is fixed.

The beneficial effects of the utility model are: the activity of rectilinear transducer is greatly improved, it is described in the utility model The ability that linear displacement transducer adapts to complex environment is stronger, and the accuracy of measurement is higher.

Detailed description of the invention:

Fig. 1 is the side schematic view of the utility model.

Fig. 2 is the main view of the utility model.

Wherein, 1- shell, 2- limiting slot, 3- groove, 4- limiting device, 5- protrusion.

Specific embodiment

The invention will be further described With reference to embodiment.

It is the technology contents of the utility model above, now embodiment does the technical solution of the utility model following detailed Illustrate:

Combined with Figure 1 and Figure 2, present embodiment discloses a kind of linear displacement transducer, including shell 1, sensor body and Limiting device 4；1 two sides of shell offer a limiting slot 2, and limiting slot 2 is located inside shell 1, and the limiting slot 2 is close to outer The part on 1 top of shell is arranged in parallel with 1 side of shell, the top half setting at an acute angle of another part and 1 side of shell, and two The limiting slot 2 that part is constituted is integral connection；The part contacted on the limiting device 4 with shell 1 is additionally provided with a groove 3。

In embodiment, the length of groove 3 is slightly larger than the width of the shell 1, can be complete when guaranteeing that shell 1 and groove 3 contact It is stuck in groove 3 entirely without left and right displacement.

In embodiment, 4 bottom of limiting device is additionally provided with an arcuate surface, and the length of the arcuate surface is greater than shell 1 Width and be less than 4 length of limiting device.

The purpose that arcuate surface is arranged is to reduce the contact surface of shell 1 and limiting device 4 and support platform, keep away as far as possible Exempt from the not up to standard of the depth of parallelism and angle caused by tilting as the out-of-flatness bring of support platform.

In embodiment, the bottom of the shell 1 is provided with a convex body, the convex body and groove 3 on limiting device 4 Match.

The width and the groove 3 on limiting device 4 of convex body are set as groove 3 and can just block convex body.

In embodiment, the intermediate position being arranged in the limiting slot 2 of two sides is provided with a fixed stop.

Under normal conditions, it fixes a linear displacement transducer and needs two limiting devices 4, fixed stop main function is The position of limiting device 4 is limited in both ends, and middle section is blocked by block, prevents from being packed into two pieces of limiting devices 4 simultaneously When the nipped danger of hand.

In embodiment, the width of limiting device 4 is the 1/4 ~ 1/2 of 1 length of shell.

As long as the width of limiting device 4 is enough, due to the design of the limiting slot 2 of the utility model, it is only necessary to one piece of limit dress 4 are set just to fix linear displacement transducer.Therefore the 1/3 of 1 length of shell is set by the width of limiting device 4 in embodiment, It is fixed by screw.

In addition, the design of limiting slot 2 can play the role of good waterproof, anti-dust accumulation in the present embodiment.

The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model Protection scope within.
