Description

Technical Field

[0001] This utility model relates to the field of laser measurement technology, and in particular to a dual-axis photoelectric position detector. Background Technology

[0002] The dual-axis photoelectric position detector is one of the components of the laser straightness measuring instrument. Its main function is to enable measuring personnel to quickly and conveniently measure the geometric adjustment errors of the horizontal and vertical dual axes during the guide rail assembly and adjustment process, thereby improving work efficiency.

[0003] Traditional optical position detectors mainly consist of an optical lens, a dual-axis photoelectric position sensor, and a data acquisition unit. In use, they are mounted on a guide rail via a support rod and a magnetic base. A laser emitter emits a laser beam that strikes the optical lens. The data is then measured and transmitted via the dual-axis photoelectric position sensor and a Bluetooth wireless communication unit. The data is used to determine the straightness of the guide rail position, followed by calibration. The magnetic base is then continuously slid to continue probing the guide rail position. However, in practical use, it has been found that when the detector moves, the operator typically needs to manually slide the magnetic base, which is inconvenient for measurement and recording, reducing the detector's effectiveness and convenience, and decreasing assembly and adjustment efficiency. Utility Model Content

[0004] The technical problem this invention aims to solve is that when the detector moves, staff generally need to manually slide the magnetic base, which is very inconvenient for general measurement and recording, reducing the effectiveness and convenience of the detector and decreasing the efficiency of assembly and adjustment.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a dual-axis photoelectric position detector, including a detector body, a lens fixedly connected to the surface of the detector body, two support rods fixedly connected to one side surface of the detector body, the other end of the two support rods being fixedly connected to a magnetic base, and an auxiliary device fixedly connected to one side surface of the magnetic base, the auxiliary device causing the detector body to slide on the guide rail.

[0006] The effect achieved by the above components is as follows: when the detector body is in use, the magnetic base is first installed on the guide rail for assembly and adjustment. Then, the laser flatness measuring instrument is operated to make the laser emitter emit laser light, which hits the lens of the detector body, thereby simultaneously measuring the horizontal and vertical dimensions. The measurement data is transmitted through the Bluetooth wireless communication unit. Then, during the measurement process, the position of the detector body is slidably adjusted by the auxiliary device, thereby continuously and stably assembling and adjusting the guide rail.

[0007] Preferably, the auxiliary device includes a mounting block, which is fixedly connected to the surface of the magnetic base. A rotating rod is rotatably connected through the surface of the mounting block. Rollers are fixedly connected to the arc surfaces at both ends of the rotating rod. A servo motor is fixedly connected to one side surface of the magnetic base. A first gear is fixedly connected to the output end of the servo motor. A second gear is fixedly connected to the arc surface of the rotating rod. The first gear and the second gear mesh with each other.

[0008] The effects achieved by the above components are as follows: the detector body can be adjusted more conveniently and quickly during use, and the sliding gap position can be more accurate and faster. The guide rail can be assembled and adjusted and calibrated more quickly, thus improving the effectiveness and convenience of the detector body.

[0009] Preferably, a bearing is fixedly connected to the arc surface of the rotating rod, the inner ring of the bearing is fixedly connected to the arc surface of the rotating rod, and the outer ring of the bearing is fixedly connected to the inner wall of the mounting block.

[0010] The effect achieved by the above components is that, through the bearing arrangement, the rotating rod and the mounting block are less prone to rotational wear during use, thereby ensuring the smooth rotation of the roller and better driving the movement of the detector body.

[0011] Preferably, a stabilizing ring is fixedly connected to one side surface of the magnetic base, and the inner wall of the stabilizing ring is slidably connected to the arc surface of the first gear and the second gear.

[0012] The effect achieved by the above components is that, through the setting of the stabilizer, the meshing of the first gear and the second gear is more stable and less prone to misalignment or displacement, thereby ensuring the normal use of the auxiliary device.

[0013] Preferably, a reinforcing ring, which is a rubber ring, is fixedly connected to the arc surface of the roller.

[0014] The effect achieved by the above components is that, by setting the reinforcing ring, the friction is further increased when the roller rolls on the worktable, thereby making the sliding of the magnetic base more stable and preventing the roller from slipping.

[0015] Preferably, the surface of the detector body is provided with a protective device, the protective device including two slide rails, the two slide rails are respectively fixedly connected to the surface of the detector body, and the two slide rails are respectively located on both sides of the lens. The inner walls of the two slide rails are slidably connected to a protective plate. A frame is fixedly connected to one side surface of the protective plate, and a block is fixedly connected to the surface of the detector body. The block engages with the inner wall of the frame.

[0016] The effect achieved by the above components is that when the detector body is idle, the lens is not easily touched or bumped by other objects, which would cause the lens to be scratched or broken, affecting the laser reception and measurement, thus ensuring the normal use of the detector body.

[0017] Preferably, the surface of the protective plate is threaded with bolts, and the bolts abut against the surface of the detector body.

[0018] The effect achieved by the above components is as follows: by setting the bolts, when the protective plate slides and the lens is opened and exposed, it rotates, so that the bolts contact and press against the detector body, thereby stabilizing the position of the protective plate, making it less prone to abnormal sliding, and ensuring the normal use of the detector body.

[0019] Preferably, a connecting rope is fixedly connected to the surface of the bolt, and the other end of the connecting rope is fixedly connected to the surface of the protective plate.

[0020] The effect achieved by the above components is that the bolts are easier to handle during use due to the connecting rope, and the bolts are less likely to fall off or be lost during use, thus better securing the protective plate.

[0021] The beneficial effects of this utility model are:

[0022] The detector body of this invention allows for more convenient and faster position adjustment during use, and makes the sliding gap position more accurate and faster. It also allows for faster assembly and adjustment of the guide rail, thus improving the effectiveness and convenience of the detector body. Attached Figure Description

Detailed Implementation

[0029] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0030] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" or "linked" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a mechanical connection or an electrical connection; it can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] Figure 1 The dual-axis photoelectric position detector shown includes a detector body 1. A lens 2 is fixedly connected to the surface of the detector body 1. Two support rods 3 are fixedly connected to one side surface of the detector body 1. The other ends of the two support rods 3 are fixedly connected to a magnetic base 4. An auxiliary device 5 is fixedly connected to one side surface of the magnetic base 4. The auxiliary device 5 allows the detector body 1 to slide and move on a guide rail. When the detector body 1 is in use, the magnetic base 4 is first installed on the guide rail. Then, the laser straightness measuring instrument is operated to make the laser emitter emit a laser, which hits the lens 2 of the detector body 1, thereby simultaneously measuring horizontal and vertical dimensions. The measurement data is transmitted through a Bluetooth wireless communication unit. During the measurement process, the position of the detector body 1 is slidably adjusted by the auxiliary device 5, thereby continuously and stably adjusting the guide rail. A protective device 6 is provided on the surface of the detector body 1.

[0032] Figure 1 , Figure 2 and Figure 3The auxiliary device 5 shown includes a mounting block 51, which is fixedly connected to the surface of the magnetic base 4. A rotating rod 52 is rotatably connected through the surface of the mounting block 51. Rollers 53 are fixedly connected to the arc surfaces at both ends of the rotating rod 52. A servo motor 54 is fixedly connected to one side surface of the magnetic base 4. A first gear 55 is fixedly connected to the output end of the servo motor 54. A second gear 56 is fixedly connected to the arc surface of the rotating rod 52. The first gear 55 and the second gear 56 mesh. When the detector body 1 is in use, the magnetic base 4 is first installed on the mounting guide rail. Then, the laser straightness measuring instrument is operated to make the laser emitter emit laser light, which hits the lens 2 of the detector body 1, thereby simultaneously measuring horizontal and vertical dimensions. The measurement data is transmitted through the Bluetooth wireless communication unit. Then, during the measurement process, the magnetic base 4 is activated. The servo motor 54 of the base 4 causes the first gear 55 on the output end of the servo motor 54 to rotate. Because the second gear 56 fixedly connected to the rotating rod 52 meshes with the first gear 55, the rotating rod 52 will rotate on the mounting block 51 fixedly connected to the surface of the magnetic base 4 under the drive of the servo motor 54. This causes the rollers 53 fixedly connected to both ends of the rotating rod 52 to rotate, making the rollers 53 contact and roll on the worktable. At this time, the magnetic base 4 will slide on the guide rail to adjust the position of the detector body 1, thereby continuously adjusting the measurement distance and debugging the assembly state of the guide rail. When the detector body 1 is in use, the position can be adjusted more conveniently and quickly, and the sliding distance position can be more accurate and faster. The assembly and calibration of the guide rail can be adjusted more quickly, improving the use effect and convenience of the detector body 1.

[0033] Figure 1 , Figure 2 and Figure 3 A bearing 57 is fixedly connected to the arc surface of the rotating rod 52 shown. The inner ring of the bearing 57 is fixedly connected to the arc surface of the rotating rod 52, and the outer ring of the bearing 57 is fixedly connected to the inner wall of the mounting block 51. By setting the bearing 57, the rotating rod 52 is less prone to rotational wear between the rotating rod 52 and the mounting block 51 during use, thereby ensuring the smooth rotation of the roller 53 and better driving the movement of the detector body 1.

[0034] Figure 1 , Figure 2 and Figure 3 A stabilizing ring 58 is fixedly connected to one side surface of the magnetic base 4 shown. The inner wall of the stabilizing ring 58 is slidably connected to the arc surface of the first gear 55 and the second gear 56. Through the setting of the stabilizer, the meshing of the first gear 55 and the second gear 56 is more stable and less prone to misalignment, thereby ensuring the normal use of the auxiliary device 5.

[0035] Figure 1 , Figure 2 and Figure 3 A reinforcing ring 59 is fixedly connected to the arc surface of the roller 53 shown. The reinforcing ring 59 is a rubber ring. By setting the reinforcing ring 59, the friction of the roller 53 is further increased when it rolls on the worktable, so that the sliding of the magnetic base 4 is more stable and the roller 53 is less likely to slip.

[0036] Figure 1 and Figure 4 The protective device 6 shown includes two slide rails 61, which are fixedly connected to the surface of the detector body 1 and located on both sides of the lens 2. A protective plate 62 is slidably connected to the inner walls of the two slide rails 61. A frame 63 is fixedly connected to one side of the protective plate 62, and a block 64 is fixedly connected to the surface of the detector body 1. The block 64 engages with the inner wall of the frame 63. When the detector body 1 is no longer in use and is stored, the protective plate 62 is slid, allowing it to slide along the inner wall of the slide rail 61 on the surface of the detector body 1 until it slides to the position that shields the lens 2. This causes the block 64 fixedly connected to the protective plate 62 to engage with the block 64 on the surface of the detector body 1, fixing the position of the protective plate 62. In this case, when the detector body 1 is idle, the lens 2 is less likely to be touched or bumped by other objects, preventing scratches or breakage of the lens 2 and affecting laser reception and measurement, thus ensuring the normal use of the detector body 1.

[0037] Figure 1 and Figure 4 The protective plate 62 shown has a threaded bolt 65 connected to its surface. The bolt 65 abuts against the surface of the detector body 1. The bolt 65 allows the protective plate 62 to slide and the lens 2 to be opened and exposed. When the bolt 65 is installed, it rotates and the bolt 65 contacts and presses against the detector body 1, thus stabilizing the position of the protective plate 62 and preventing abnormal sliding, ensuring the normal use of the detector body 1. A connecting rope 66 is fixedly connected to the surface of the bolt 65. The other end of the connecting rope 66 is fixedly connected to the surface of the protective plate 62. The connecting rope 66 makes it easier to remove the bolt 65 during use and prevents it from falling off or being lost, thus better fixing the position of the protective plate 62.

[0038] Working principle: When the detector body 1 is in use, the magnetic base 4 is first installed on the guide rail. Then, the laser flatness measuring instrument is operated to make the laser emitter emit a laser beam, which hits the lens 2 of the detector body 1, thereby simultaneously measuring horizontal and vertical dimensions. The measurement data is transmitted through the Bluetooth wireless communication unit. During the measurement process, the servo motor 54 of the magnetic base 4 is started, causing the first gear 55 on the output end of the servo motor 54 to rotate. Because the second gear 56 fixedly connected to the rotating rod 52 meshes with the first gear 55, the rotating rod 52 will rotate on the servo motor 54. Driven by the rotation of the mounting block 51 fixedly connected to the surface of the magnetic base 4, the rotating rod 52 rotates, causing the rollers 53 fixedly connected to both ends to rotate. The rollers 53 then roll in contact on the worktable. At this time, the magnetic base 4 slides along the guide rail, adjusting the position of the detector body 1 and continuously adjusting the measurement distance. This allows for debugging of the guide rail assembly status. When using the detector body 1, the position can be adjusted more conveniently and quickly, and the sliding distance position can be more accurate and faster. The guide rail assembly can be adjusted and calibrated more quickly, improving the usability and convenience of the detector body 1.

[0039] When the detector body 1 is no longer in use and is stored idle, the sliding protective plate 62 slides along the inner wall of the slide rail 61 on the surface of the detector body 1 until the protective plate 62 slides to the position of the shielding lens 2. The locking block 64 fixedly connected on the protective plate 62 engages with the locking block 64 on the surface of the detector body 1, thus fixing the position of the protective plate 62. At this time, when the detector body 1 is idle, the lens 2 is not easily touched or bumped by other objects, which would cause the lens 2 to be scratched or broken, affecting the laser reception measurement, thus ensuring the normal use of the detector body 1.
