Therefore, the device is provided with more kinds of sensor clamps, and the types of naturally clampable sensors are increased, so that the types of detectable sensors are increased, the functions are obviously enhanced, and the universality is better.
Specifically, since the slider of the displacement sensor clamped by the displacement sensor clamp is connected with the linear driving part and can move along the central axis of the linear driving part, when the linear driving part drives the slider of the sensor to slide, the linear accuracy, the repetition accuracy and other characteristics of the displacement sensor can be judged to be in accordance with the standard by taking the central axis of the linear driving part as a reference.

And because the central axis of the angle sensor clamped by the angle sensor clamp can be coaxial with the central axis of the linear driving part, the shaft can be realized when the angle sensor is installed, so that whether the sensitivity and the linear precision of the rapid detection angle sensor meet the standards or not can be detected. Similarly, the center axis of the clamped angle sensor can be coaxial with the center axis of the linear driving part, for example, the angle sensor clamps can be fixed to two ends of the linear driving part, and different angle sensor clamps can be set according to the types and types of the angle sensors, so that the types and types of the detectable angle sensors are increased, and the universality is improved.
Because the proximity switch clamped by the proximity switch clamp can respond to the detected object clamped by the connecting part, the installation position of the proximity switch clamp can be less than one, the number of the proximity switches which can be naturally used for detection can be more than one, the types and the number of the proximity switches which can be simultaneously detected are more, and the universality is improved.
In summary, the multifunctional multi-sensor detection device provided by the application has better universality due to the increase of detection functions and detection types; the multifunctional multi-sensor detection device comprising the multifunctional multi-sensor detection device has a wide application range.

The embodiment of the application discloses a multifunctional multi-sensor detection device which comprises a bottom plate 1, a sliding rail and sliding block 2, a linear driving part 3, a connecting part 4, a displacement sensor clamp 5, an angle sensor clamp 6 and a proximity switch clamp 7.
In this particular embodiment, a grating sensor is used as a standard test ruler to test other types of sensors to complete calibration of their static and dynamic performance.
In this particular embodiment, the base plate 1 is a generally flat metal plate placed horizontally, mainly for supporting other components. The base plate 1 is fixedly provided with a sliding rail slide block 2, a displacement sensor clamp 5, an angle sensor clamp 6 and a proximity switch clamp 7.
The slide rail slider 2 includes a slide rail 21 and a slider 22, and the slide rail 21 is horizontally fixed to the base plate 1 so that the slider 22 can horizontally slide along the slide rail 21. To ensure the detection accuracy, in this particular embodiment, the slide rail 21 adopts a dovetail rail, and correspondingly, the slider 22 is a dovetail groove. Of course, the sectional shapes of the slide rail 21 and the slider 22 may be other types, and are not limited thereto.
The linear driving part 3 is fixed above the slide rail slider 2 and is used for driving the screw nut 31 of the connecting part 4 along the slide rail slider 4. In this particular embodiment, the screw nut 31 is located directly above the slide rail slider 2, and mainly includes a screw 311 and a nut seat 312. The length of the screw 311 is approximately equal to the length of the slide rail 21, and two ends of the screw are horizontally fixed to two ends of the slide rail 21 through corresponding supports. The nut seat 312 penetrates the screw 311, and when the screw 311 rotates, the nut seat 312 horizontally slides along the screw 311. Of course, other driving methods may be used for the linear driving section 3. The linear driving unit 3 further includes a driving device, specifically, a coupling, a servo motor, and the like, which are connected to the screw 311 of the screw nut 31, to drive the slider 22 to slide, thereby realizing detection.
The connecting portion 4 is connected between the linear driving portion 3 and the slide rail slider 2, in this specific embodiment, the connecting portion 4 is specifically a connecting plate, specifically disposed between the nut seat 312 and the slider 22, the connecting plate fixedly connects the nut seat 312 and the slider 22 into a whole through bolts and nuts, and when the nut seat 312 slides horizontally, the connecting portion 4 and the slider 22 are driven to slide horizontally along the slide rail 21. Of course, other ways of connecting the connecting portion 4, the nut seat 312 and the slider 22 together may be used. It is to be noted that the length of the connecting portion 4 is not so short as to fix various objects to be detected when detecting the sensitivity of the proximity switch.
The slider of the displacement sensor held by the displacement sensor holder 5 is connected to the linear driving section 4 and is movable along the central axis of the linear driving section 3. The displacement sensor clamp 5 is usually located at a side of the sliding rail slider 2, so that the clamped displacement sensor is parallel to the central axis of the screw 311, and the displacement sensor mounted on the displacement sensor clamp 5 is usually a linear displacement sensor. The displacement sensor clamp 5 comprises a segmented displacement sensor clamp 51 and a hidden displacement sensor clamp 52 which are respectively positioned at two sides of the sliding rail slide block 2.
In this particular embodiment, segmented displacement sensor clamp 51 includes a baffle assembly 511, a baffle rod 512, and a connecting tab 513. The baffle assembly 511 is composed of two metal plates which are staggered and parallel along the vertical direction of the central axis of the sliding rail and sliding block 2 and a fixing rod which penetrates through the metal plates, so that the displacement sensor is convenient to clamp quickly. Typically, the baffle assembly 511 is welded with a number of groups, the number of which is mainly determined by the measuring range of the displacement sensor to be measured, and the fixing manner is not unique. In this embodiment, the segmented displacement sensor clamp 51 is located at one side of the sliding rail 21, and includes two sets of baffle assemblies 511, one set is close to the end of the sliding rail 21, the other set is far away from the end of the sliding rail 21, and a certain distance is arranged between the two sets of baffle assemblies 511, and the two baffle assemblies are horizontally distributed along the side surface of the bottom plate 1. The baffle 512 is usually fixed on the base plate 1 and is near the other end of the slide rail 21, and its central axis perpendicularly intersects with the extension line of the central line of the baffle assembly 511, mainly for protecting the displacement sensor. In this embodiment, the bar 512 is a cylindrical metal bar fixed to the base plate 1, but the shape of the bar 512 is not limited thereto. The connection piece 513 is disposed on the nut seat 312 and is mainly used for connecting with the slider of the displacement sensor, and in this embodiment, the connection piece 513 includes two iron metal sheets and is connected with the nut seat 312 through a magnet. For a displacement sensor with a small measuring range, the sliding head of the displacement sensor to be measured is connected with the connecting sheet 513, when the movement range of the sliding head is too large, the connecting sheet 513 is separated from the sliding head of the displacement sensor by the baffle rod 512, and naturally, the sliding head of the displacement sensor is separated from the nut seat 312 and the sliding block 22, so that the traction of the displacement sensor is stopped, and the displacement sensor is prevented from being transitionally stretched.
It is noted that when the range of the displacement sensor to be detected is smaller than the movement range of the slider 22, the detection can be accomplished only by using the baffle assembly 511 near the end of the slide rail 21; when the range of the displacement sensor to be detected is larger than the movement range of the sliding block 22, the baffle assemblies 511 close to the end parts of the sliding rails 21 are used for clamping to finish partial detection, then the displacement sensor is moved backwards, the baffle assemblies 511 far away from the end parts of the sliding rails 21 are used for clamping, and the distance from the middle part of the displacement sensor to a longer distance can be measured.
In this embodiment, the hidden displacement sensor fixture 52 is located on the other side of the slide rail 21, and includes a main plate 521, a rotating shaft 522, a hidden plate 523, a bi-directional screw nut 524, a metal clamping plate 525, a working magnet 526, and a hidden magnet 527. The main board 521 is mounted on the side of the base board 1, is generally hollow, and has a square outer shape Zhou Changkai. The rotating shaft 522 is fixed on the inner side wall of the main board 521. The hiding plate 523 is usually a metal iron plate, and its bottom end passes through the side of the main plate 521 and is hinged to the rotating shaft 522, so that the hiding plate 523 can rotate out from the side of the main plate 521 around the rotating shaft 522 or rotate from the outside to be parallel to the side of the main plate 521, which is convenient for saving space. A bi-directional screw nut 524 is installed on one side of the hidden plate 523, which is rotatably close to the side of the main plate 521, and when screws with two opposite rotation directions are rotated at both ends, two nut seats on the bi-directional screw nut 524 are simultaneously close to or simultaneously far away from each other so as to clamp or unclamp the displacement sensor; in order to realize convenient clamping, a metal clamping plate 525 is respectively fixed on the corresponding surfaces of the two nut seats, and the natural metal clamping plate 525 can pass through the bidirectional screw nut 524, so that the clamping area is increased. The working magnet 526 is usually fixed inside the main board 521 and is usually located at the tail of the hidden board 523, and when the working magnet 526 has magnetism, the hidden board 523 rotates around the rotation shaft 522 to the working magnet 526, and the head of the working magnet rotates out of the main board 521, in this embodiment, when the hidden board 523 rotates to be perpendicular to the side of the main board 521, this state is the working state. The hidden magnet 527 is also fixed inside the main board 521, in order to ensure that the displacement sensor to be detected is kept parallel to the central axis of the screw 311, the hidden magnet 527 is generally staggered from the working magnet 526 along the central axis of the main board 521, when the hidden magnet 527 has magnetism, the head of the hidden board 523 rotates to the hidden magnet 527 around the rotating shaft 522, so that the head of the hidden board 523 enters the main board 521, and in this embodiment, when the hidden board 523 rotates to the side of the main board 521 to be parallel, this state is the hidden state. The hidden displacement sensor can effectively save the occupied area and is beneficial to beautifying the appearance. In addition, the hidden displacement sensor holder 52 further includes solenoid valves mounted on the main plate 521 and respectively connected to the working magnet 526 and the hidden magnet 527 for switching the working states of the working magnet 526 and the hidden magnet 527, so as to rapidly clamp the displacement sensor. The displacement sensor clamped by the hidden displacement sensor clamp 52 is a standard detection ruler, specifically a grating ruler, of course, the hidden displacement sensor clamp 52 can also clamp other types of sensors, especially square sensors, and only the appearance and the measuring range of the sensor to be detected need to meet the clamping condition.
Of course, the number and the position of the installation of the segmented displacement sensor holder 51 and the hidden displacement sensor holder 52 are not limited thereto, and may be appropriately adjusted depending on the type of the sensor to be actually measured.
The angle sensor holder 6 has a size adjustment portion, and the central axis of the angle sensor held by it can be coaxial with the central axis of the linear drive portion 3. The angle sensor holder 6 is typically located on an extension of the centre line of the screw nut 31, mainly for holding a cylindrical angle sensor. The angle sensor holder 6 includes a support plate 61, a guide rod 62, a V-shaped clamp block 63, an adjustment knob 64, and a clamp plate 65.
The support plate 61 is a general metal plate, and countersunk screw holes are formed at each of four corners of the support plate 61 so as to fix the support plate 61 to the base plate 1 with anchor bolts.
The guide rods 62 comprise two cylindrical metal rods which are respectively positioned at two ends of the support plate 61, and the bottoms of the two guide rods 62 are fixed on the support plate 61; the middle section of the guide rod 62 is a polished rod and is used for installing a V-shaped clamping block 63; the top of the clamp is provided with a threaded rod for installing the clamp plate 65; of course, the number of guide rods 62 is not limited thereto.
The V-shaped clamping block 63 generally penetrates through the two guide rods 62 and is mainly used for realizing the shaft alignment of the angle sensor; in this embodiment, in order to conveniently realize quick axis alignment of cylindrical angle sensors with different sizes, the V-shaped clamping block 63 is symmetrically designed, that is, two inclined planes are symmetrical and form 90 °, meanwhile, the two inclined planes of the V-shaped clamping block 63 are parallel to the central axis of the screw 311, and the extension line of the central axis of the screw 311 is located on the longitudinal symmetry center plane of the V-shaped clamping block 63, so when the cylindrical angle sensor is placed on the two inclined planes of the V-shaped clamping block 63, according to the geometric principle, the central axis of the cylindrical angle sensor and the central axis of the screw 311 have small error in the horizontal direction, and only the displacement of the two central axes in the vertical direction needs to be adjusted during installation, thereby facilitating quick axis alignment; because the two cylindrical through holes formed on the V-shaped clamping block 63 are mainly used for the guide rod 62 to insert, the cylindrical surfaces of the two cylindrical through holes of the V-shaped clamping block 63 are matched with the cylindrical surface of the polish rod part of the guide rod 2, and the natural V-shaped clamping block 63 can slide along the guide rod 62.
The adjusting knob 64 is generally disposed between the V-shaped clamping block 63 and the supporting plate 61, and mainly comprises two parts, one part is a cylindrical block fixed at the bottom of the V-shaped clamping block 63, the other part is a threaded rod fixed at the bottom of the cylindrical block, and the bottom end of the threaded rod is screwed into the supporting plate 61, so that when the threaded rod is rotated, the V-shaped clamping block 63 moves up and down along with the threaded rod to realize shaft alignment.
The clamping plate 65 is installed at the top ends of the two guide rods 62, and two cylindrical through holes are formed in the clamping plate 65 so that the clamping plate 65 can move along the central axis of the guide rods 62, thereby realizing size adjustment from the upper part of the guide rods 62 according to the external dimension of the cylindrical angle sensor. In order to fasten the cylindrical angle sensor to be measured by using the clamping plate 65, nuts are respectively arranged at the top parts of the two guide rods 62, and the clamping plate 65 is jacked in to realize fixation. From this, the size adjustment portion includes adjusting guide arm 62, V-arrangement clamp block 63, adjust knob 64 and splint 65, realizes the size adjustment from cylindrical angle sensor's upper and lower two directions, conveniently accomplishes cylindrical angle sensor's counter shaft and is fixed.
The proximity switch held by the proximity switch holder 7 can respond to the object to be detected held by the linear driving section 3. The proximity switch fixture 7 includes a bent metal frame fixed to the base plate 1 for supporting the proximity switch so as to respond to an object to be detected mounted at the bottom of the connection part 4. In this embodiment, the bent metal frames include a first bent metal frame 71 and a second bent metal frame 72 at two ends of the sliding rail 21, and correspondingly, two metal support plates for supporting the object to be detected, namely, a first metal support plate 73 and a second metal support plate 74, are disposed at the bottom of the connecting portion 4. It should be noted that the proximity switches mounted on the first bending metal frame 71 and the second bending metal frame 72 may be two or the same kind of proximity switches with detection, wherein the types of proximity switches to be detected may be capacitive proximity switches, inductive proximity switches, magneto-electric proximity switches, eddy current proximity switches, hall proximity switches, and the like. For different types of proximity switches, the first metal support plate 73 and the second metal support plate 74 on the connecting portion 4 can respectively fix different objects to be detected, but it is required to ensure that the type of the proximity switch on the bent metal frame corresponds to the type of the object to be detected on the metal support plate, for example, when the first bent metal frame 71 is fixed with a capacitive proximity switch, the object to be detected fixed on the first metal support plate 73 is necessarily another polar plate; when the first bending metal frame 71 is fixed to an inductive proximity switch, a magneto-electric proximity switch, or an eddy current proximity switch, the object to be detected fixed to the first metal support plate 73 may be a metal plate. The proximity switch fixture 7 can be used for checking the sensitivity of various types of proximity switches, and when the object to be detected fixed on the connecting part 4 moves along with the sliding block 22 to the range of the action distance, the proximity switch acts to measure the range of the action distance so as to obtain the sensitivity of the proximity switch.
In summary, the multifunctional multi-sensor detection device provided by the application mainly comprises the sliding rail slider 2, the screw nut 31, the connecting part 4, the displacement sensor clamp 5, the angle sensor clamp 6 and the proximity switch clamp 7. The nut seat 312 of the screw nut 31 is connected with the slide block 22 of the slide rail slide block 2 into a whole through the connecting part 4 so as to drive the displacement sensor in the displacement sensor clamp 5 to move, so as to finish detecting the displacement sensor; the hidden type displacement sensor clamp and the sectional type displacement sensor clamp of the displacement sensor clamp 5 are adjustable mechanisms, so that the clamping and detection of the displacement sensor to be measured with different measuring ranges and different shapes can be suitable; the angle sensor clamp 6 not only can detect the angle sensor, but also can increase the variety of the angle sensor to be detected by the size adjusting part; the proximity switch fixture 7 can be implemented to detect various types of proximity switches. Therefore, the multifunctional multi-sensor detection device provided by the application not only can detect the performances of the displacement sensor, the angle sensor and the proximity switch simultaneously or independently, and has more detection functions, but also can detect the types and the models of the sensors, so that the universality is better.
The application also provides a multifunctional multi-sensor detection device which comprises a measurement and control device and the multifunctional multi-sensor detection device connected with the measurement and control device. The measurement and control device comprises an acquisition card, a computer and functional software, and converts displacement signals into digital signals to realize detection. Therefore, the application range of the multi-function multi-sensor detecting apparatus including the multi-function multi-sensor detecting device is naturally wide.
