[0039] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0040] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0041] The present invention is further described in detail below through specific implementation examples in conjunction with the accompanying drawings.
[0042] See also Figure 1-Figure 3The present embodiment provides a sensor mounting device, which includes a fixing frame 100, a mounting plate 200, a sensor, an adjusting member 300 and an anti-collision member 400; an elastic hinge 110 is provided on the fixing frame 100, the elastic hinge 110 is fixedly connected to the mounting plate 200, the adjusting member 300 cooperates with the mounting plate 200 and the fixing frame 100 respectively, the adjusting member 300 can adjust the distance between the mounting plate 200 and the fixing frame 100, and the adjusting member 300 can adjust the deflection angle of the mounting plate 200 relative to the fixing frame 100; the sensor and the anti-collision member 400 are both installed on the side of the mounting plate 200 away from the fixing frame 100; in a direction perpendicular to the mounting plate 200, the anti-collision member 400 protrudes from the sensor.
[0043] In the sensor mounting device provided in this embodiment, the elastic hinge 110 can form a certain elastic limit for the mounting plate 200 on which the sensor is mounted, so that the elastic hinge 110 can not only provide a certain support for the mounting plate 200, but also allow the mounting plate 200 to move and deflect to a certain extent relative to the fixing frame 100.
[0044] Among them, the adjusting member 300 can adjust the distance between the mounting plate 200 and the fixing frame 100 to the target distance, that is, the mounting plate 200 can move relative to the fixing frame 100 in a direction perpendicular to its own board surface; in addition, the adjusting member 300 can also adjust the deflection angle of the mounting plate 200 relative to the fixing frame 100, that is, the mounting plate 200 can rotate relative to the fixing member 100 around two axes of the mounting plate 200 that are parallel to its own board surface and perpendicular to each other. In other words, the sensor mounting device provided in this embodiment can realize the adjustment of the planar posture freedom of the sensor.
[0045] When a collision occurs during testing or movement, the more protruding anti-collision piece 400 will contact and collide with the measuring target surface. After the anti-collision piece 400 is hit by the measuring target surface, the mounting plate 200 will move away from the measuring target surface and compress the elastic hinge 110. After being compressed, the elastic hinge 110 will undergo elastic deformation to adapt to the movement of the mounting plate 200. During this process, the anti-collision piece 400 will follow the mounting plate 200 away from the measuring target surface, so that the collision is buffered and the damage to the measuring target surface is reduced. In addition, the presence of the anti-collision piece 400 makes it difficult for the sensor to contact the measuring target surface. Therefore, the sensor will basically not be damaged during the collision, which provides good protection for the sensor, extends the service life of the sensor, and has higher safety.
[0046] When the measuring target surface is separated from the anti-collision component 400, the mounting plate 200 will be reset under the elastic reset force of the elastic hinge 110, that is, after the collision, the sensor can reset itself without human intervention, and the operating efficiency is high.
[0047] A ball-and-groove pair 500 may be provided between the fixing frame 100 and the mounting plate 200. The ball-and-groove pair 500 may specifically include a pressing piece 510 having a spherical convex surface, a groove body 520 having a spherical groove surface, and an elastic connecting piece 530. The pressing piece 510 having a spherical convex surface may be connected to the fixing frame 100 through the elastic connecting piece 530, and the groove body 520 having a spherical groove surface may be fixed to the mounting plate 200. By matching the spherical convex surface of the pressing piece 510 with the spherical groove surface of the groove body 520, the function of the ball-and-groove pair 500 may be exerted, and the mounting plate 200 may be deflected around the ball-and-groove pair 500, so that the mounting plate 200 has greater stability. At the same time, the elastic deformation of the elastic connecting piece 530 may be used to realize the translation of the mounting plate 200, thereby meeting the translation requirement of the mounting plate 200.
[0048] Preferably, a limiting groove 120 can be opened on the fixing frame 100, and the elastic connecting member 530 can be installed in the limiting groove 120, so that the limiting groove 120 can limit the elastic connecting member 530, the elastic connecting member 530 is not easy to bend, and has strong reliability. Moreover, when disassembly is required, the elastic connecting member 530 can be directly taken out of the limiting groove 120, which is very convenient.
[0049] Correspondingly, a blind hole can be opened on the pressing piece 510 with a spherical convex surface, and the outer end of the elastic connecting piece 530 can be matched with the blind hole, so that the blind hole can limit the elastic connecting piece 530, the elastic connecting piece 530 is more difficult to bend, and when disassembly is required, the elastic connecting piece 530 can be directly taken out of the blind hole, which is very convenient.
[0050] The pressing member 510 is preferably a column, which facilitates the matching between the column and the limiting groove 120 .
[0051] like Figure 2 As shown, two mutually perpendicular axes parallel to the mounting plate 200 are defined as the X-axis and the Y-axis respectively, and the axis perpendicular to the mounting plate 200 is defined as the Z-axis; based on the ball-and-groove pair 500, the sensor can be arranged as follows:
[0052] The number of sensors is three, namely, a first displacement sensor 600 and two second displacement sensors 700. The first displacement sensor 600 and the ball-and-socket pair 500 are arranged back to back, and the two second displacement sensors 700 are arranged on opposite sides of the ball-and-socket pair 500 along the X-axis direction. In this way, the first displacement sensor 600 can be used to measure the X-direction displacement, and the two second displacement sensors 700 can be used to measure the Z-direction displacement. By analyzing the Z-direction displacements measured by the two second displacement sensors 700, R Y The corner.
[0053] The above arrangement is not only easy to control but also has an accurate measurement structure. Of course, it is not limited to the above arrangement of sensors. Other arrangement of sensors that can achieve the measurement purpose are within the protection scope of the present invention.
[0054] Specifically, the mounting plate 200 can be optionally set to a rectangular shape, and a plurality of claws 130 can be set on the side of the fixing frame 100 facing the mounting plate 200, and the plurality of claws 130 are surrounded on three sides of the mounting plate 200. In this way, the mounting plate 200 can be inserted from the side where the claws 130 are not set into the area surrounded by the plurality of claws 130.
[0055] Each of the above-mentioned claws 130 has a bending portion 131, and the bending portion 131 is opposite to the side of the mounting plate 200 facing away from the fixing frame 100, and a threaded hole is opened on the bending portion 131. Accordingly, the above-mentioned adjusting member 300 is set as a first threaded connecting member, and the first threaded connecting member is matched with the threaded hole. After the end of the first threaded connecting member passes through the threaded hole, it can abut against the mounting plate 200. In this way, under the joint action of the first threaded connecting member and the elastic hinge 110, the mounting plate 200 can be locked stably. Of course, adding a ball groove pair 500 will further improve the stability of the mounting plate 200.
[0056] It should be noted that the translation and deflection of the mounting plate 200 can be achieved by adjusting the depth of the first threaded connector screwed into the threaded hole.
[0057] Preferably, the above-mentioned claws 130 can be set to three, and the three claws 130 are respectively defined as the first claw, the second claw and the third claw. Correspondingly, three sides of the rectangular mounting plate 200 are respectively defined as the first side, the second side and the third side, and the two ends of the first side are respectively connected to the second side and the third side, that is, the second side is opposite to the third side. The first claw is set at a position close to the middle part of the first side, the second claw is set close to the end of the second side facing away from the first side, and the third claw is set close to the end of the third side facing away from the first side. In this way, fewer claws can be used to achieve reliable locking and smooth adjustment of the mounting plate 200, and the operation is also easier.
[0058] Preferably, a spring sheet 111 and a protrusion 112 can be provided in the specific structure of the above-mentioned elastic hinge 110. Accordingly, a window is provided on the fixing frame 100, and the spring sheet 111 and the protrusion 112 are both provided in the window; one end of the spring sheet 111 is connected to the fixing frame 100, and the other end of the spring sheet 111 is suspended and connected to the protrusion 112, the protrusion 112 protrudes from the surface of the fixing frame 100 facing the mounting plate 200, and the protrusion 112 is fixedly connected to the mounting plate 200. When the mounting plate 200 moves toward the fixing frame 100, the protrusion 112 is pushed to move synchronously, and the spring sheet 111 is adaptively deformed in the window. In this way, the supporting effect and resettability of the elastic hinge 110 on the mounting plate 200 can be achieved.
[0059] Preferably, the protrusion 112 and the mounting plate 200 can be fixedly connected via a second threaded connection piece, which not only ensures good connection reliability but also enables the mounting plate 200 to be disassembled.
[0060] The spring piece 111 , the protrusion 112 and the fixing frame 100 may be provided as an integrally formed structure, so as to ensure good structural strength.
[0061] Specifically, the spring piece 111 can be formed by cutting on the fixing frame 100 , that is, by cutting along three sides of a rectangle on the fixing frame 100 .
[0062] Preferably, a plurality of anti-collision members 400 may be provided, and the plurality of anti-collision members 400 may surround the peripheral side of the sensor, so that the anti-collision members 400 may better protect the sensor and prevent the sensor from collision.
[0063] This embodiment also provides an automation equipment, which has the above-mentioned sensor installation device.
[0064] Therefore, the automation equipment provided in this embodiment has all the advantages of the above-mentioned sensor installation device. When a collision occurs, the measurement target surface is less damaged, and the sensor is not easily damaged, so the safety is higher. In addition, after the collision, the sensor can reset itself, and the operating efficiency is higher.
