Description

Technical Field

[0001] This utility model relates to the technical field of grating sensors, specifically an anti-interference grating sensor. Background Technology

[0002] A grating sensor is a piece of long, rectangular optical glass with densely spaced, parallel gratings. It typically consists of a ruler grating, an indicator grating, an optical path system, and a measurement system. Grating sensors are used to measure physical quantities such as displacement, angle, and velocity, and they offer advantages such as high precision, high sensitivity, and fast response during the measurement process.

[0003] As disclosed in announcement number CN212254000U, a detection platform for a grating sensor includes a base, a drive motor, and a right side plate, with the top of the base fixedly connected to the bottom of the right side plate. This grating sensor detection platform, through the use of a threaded rod, a drive plate, a loading block, a first limiting block, a second limiting block, a first spring, a second spring, a third spring, and a fourth spring, pushes the first and second limiting blocks, placing the sensor to be tested between them. The sensor is fixed, and a magnetic block for measurement is placed at the bottom of the connecting frame. The motor is started, driving the threaded rod to rotate, and the drive plate moves the sensor, measuring the length of the magnetic block. The magnetic block can be repeatedly measured by adjusting the speed and direction of the drive motor, repeatedly verifying the reliability of the sensor under pressure measurement, thus solving the problem of incomplete reliability testing of current grating sensors.

[0004] However, existing technologies suffer from poor anti-interference performance, inconvenient adjustment of the spacing between the receiver and transmitter on both sides of the grating sensor, and the fact that the grating sensor is mostly positioned by bolts, making operation inconvenient. For example, the comparative patents listed above have this problem.

[0005] To address this issue, we propose an anti-interference grating sensor. Utility Model Content

[0006] The purpose of this invention is to provide an anti-interference grating sensor to solve the problems mentioned in the background art, such as poor anti-interference effect, inconvenient adjustment of the distance between the receiver and transmitter on both sides of the grating sensor, and the fact that the positioning of the grating sensor is mostly done by bolt installation, which is inconvenient to operate.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an anti-interference grating sensor, comprising a bottom track and grating sensor bodies disposed on the left and right sides above the bottom track;

[0008] Also includes:

[0009] The bottom track is slidably connected to vertically positioned movable plates at both ends, and the outer surface of the movable plates is fitted with mounting sleeves for height adjustment. The mounting sleeves are supported and connected to the grating sensor body by a mounting bracket with a "T"-shaped structure.

[0010] The inner wall of the grating sensor body housing is provided with epoxy resin.

[0011] Preferably, a fixed rod is fixedly connected to the lower end of the movable plate, and a spring is sleeved on the outer surface of the fixed rod. The movable end of the spring is connected to the movable plate, and the movable plate and the fixed rod form an up-and-down sliding structure.

[0012] Preferably, the lower end of the movable plate is engaged in a fixed groove located at the corresponding position on the upper end of the bottom track.

[0013] Preferably, a mounting bracket is fixedly connected to the middle of the outer side of the grating sensor body, and the mounting bracket is engaged with the middle of the mounting sleeve.

[0014] Preferably, auxiliary plates are fixedly connected to both the front and rear ends of the mounting sleeve, and a mounting bolt for limiting is threadedly connected to the middle of the auxiliary plate. The mounting bolt is inserted into the limiting plates fixed to the front and rear ends of the grating sensor body.

[0015] Preferably, a fixing strip is fixedly connected to the outer side of the movable plate, and multiple connecting grooves for limiting the position are equally spaced in the middle of the fixing strip.

[0016] Preferably, the front and rear ends of the outer side of the mounting sleeve are fixedly connected with connecting rods, and the outer side of the connecting rods is fitted with limiting brackets. The outer surface of the connecting rods is threaded with a fixing cap for locking and limiting, and the fixing caps and limiting brackets are fitted together.

[0017] Preferably, the middle part of the limiting bracket engages in the connecting groove at the corresponding position.

[0018] Compared with the prior art, the beneficial effects of this utility model are: the anti-interference grating sensor, through the setting of the mounting bracket, auxiliary plate, mounting bolt and limiting plate, facilitates the installation and positioning between the grating sensor body and the mounting sleeve, and is easy to disassemble and assemble. The sliding plate on the bottom track makes it easy to adjust the distance between the transmitter and receiver on the grating sensor body after installation. Moreover, the sliding of the mounting sleeve on the sliding plate can drive the grating sensor body to rise and fall, thereby facilitating the height adjustment of the grating sensor body.

[0019] 1. It is equipped with a movable plate and a sliding plate. The movable plate slides left and right between itself and the bottom track, which facilitates the adjustment of the distance between the receiver and transmitter between the individual grating sensor units on the left and right sides after installation.

[0020] 2. It is equipped with a mounting bracket, an auxiliary plate, a mounting bolt, and a limiting plate. The mounting bracket is engaged in the mounting sleeve to support and position the grating sensor body. The auxiliary plate, mounting bolt, and limiting plate facilitate the limiting of the grating sensor body and make it easy to disassemble and assemble the grating sensor body.

[0021] 3. It is equipped with an installation sleeve and a limiting bracket. The installation sleeve slides up and down on the outside of the moving plate, thereby adjusting the height of the grating sensor body. The limiting bracket engages with the corresponding connecting groove, which facilitates the limiting of the distance between the installation sleeve and the moving plate.

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-6 .

[0031] To address the problems of poor anti-interference performance, inconvenient adjustment of the spacing between the receiver and transmitter on both sides of the grating sensor in the existing technology, and the inconvenience of operation caused by bolt-mounted positioning of the grating sensor, this solution provides an anti-interference grating sensor. The sensor comprises a bottom track 1 and grating sensor bodies 7 positioned on the left and right sides above the bottom track 1. Vertically movable plates 2 are slidably connected to both ends of the bottom track 1, and the outer surface of the movable plates 2 is fitted with mounting sleeves 9 for height adjustment. The mounting sleeves 9 and the grating sensor bodies 7 are supported and connected by a T-shaped mounting bracket 10. The inner wall of the grating sensor body 7 is coated with epoxy resin 8.

[0032] like Figure 1 , Figure 3 , Figure 4 and Figure 5As shown, the bottom track 1 is first installed in the corresponding position using bolts. The movable plate 2 is set at the upper end of the bottom track 1. At the same time, the mounting bracket 10 is fixedly connected to the middle of the outer side of the grating sensor body 7. First, the grating sensor body 7 drives the mounting bracket 10 to engage with the inner side of the mounting sleeve 9. Then, by rotating the mounting bolt 12, which is threaded to the outer surface of the auxiliary plate 11, the mounting bolt 12 is inserted into the limiting plate 13, thereby facilitating the limiting between the mounting sleeve 9 and the grating sensor body 7. This makes it easy to install and position the grating sensor body 7, and the disassembly and assembly are relatively convenient. After installation, the movable plate 5 can be pulled upwards, and the movable plate 5 slides between itself and the fixed rod 3. The movable plate 5 compresses the spring 4, causing the spring 4 to undergo elastic deformation. The lower end of the movable plate 5 moves out of the fixed groove 6, thereby... Release the limiting position between the movable plate 2 and the bottom track 1, and then slide the movable plate 2 between the movable plate 2 and the bottom track 1 by pulling it to the left or right. The movement of the movable plate 2 can adjust the spacing between the individual grating sensor bodies 7 at the left and right ends. The left grating sensor body 7 is equipped with a receiver, and the right grating sensor body 7 is equipped with a transmitter. Alternatively, the positions of the receiver and transmitter can be reversed. By adjusting the position of the grating sensor body 7 by moving it left and right, it is easier to adjust the spacing between the receiver and transmitter. After the adjustment is completed, release the movable plate 5 directly. At this time, the spring 4 returns to its elastic deformation and pushes the movable plate 5 downward to insert into the corresponding fixed groove 6, thereby facilitating the limiting position between the movable plate 2 and the bottom track 1.

[0033] like Figure 3 and Figure 6 As shown, the mounting sleeve 9 can be pulled up or down, and the mounting sleeve 9 and the moving plate 2 can slide up and down, thereby driving the grating sensor body 7 to rise and fall above the bottom track 1, adjusting the height of the grating sensor body 7. After the height adjustment is completed, the limiting bracket 17 can be moved, and the limiting bracket 17 and the connecting rod 16 can slide, so that the middle part of the connecting rod 16 is engaged in the connecting groove 15 opened at the corresponding position in the middle of the fixing strip 14, thereby facilitating the limiting between the moving plate 2 and the mounting sleeve 9. Then, by rotating the fixing cap 18 threaded to the outer surface of the connecting rod 16, the fixing cap 18 and the limiting bracket 17 are fitted together to prevent the limiting bracket 17 from loosening. In addition, during use, the epoxy resin 8 is provided on the inner wall of the grating sensor body 7, which can play a good role in resisting electromagnetic interference.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
