Abstract
Description
Technical Field
[0001] This utility model relates to a laser alignment device, and more particularly to a laser alignment device and its corrector that performs alignment operations using a laser beam. Background Technology
[0002] A typical transmission mechanism consists of two objects that transmit power to each other, such as pulleys and sprockets. If the axis of these objects is misaligned, they will not rotate smoothly and will experience wear, vibration, wobbling, and other problems, which will in turn generate noise and shorten their service life.
[0003] Therefore, during the assembly and maintenance of this transmission mechanism, a laser alignment device is typically used to align the object and correct misalignment issues such as angular deviation, horizontal deviation, and tilt deviation. This laser alignment device comprises an emitter and several correctors. In use, the emitter and correctors are respectively mounted on the two objects. The emitter emits a laser beam towards the correctors to align and adjust the object's axis to make it parallel. However, because the several equidistant graduations on the correctors lack a clear positive and negative direction, it is difficult to determine the position of the laser beam spot, potentially leading to miscalculations or misjudgments during alignment. Therefore, the design of the corrector still needs improvement. Utility Model Content
[0004] The purpose of this invention is to provide a corrector for a laser centering device that can at least overcome the shortcomings of the prior art.
[0005] The laser centering device of this invention includes a scale and a vernier. The scale includes a scale body with a marking surface, scale units disposed along the length of the scale body on the marking surface, and positive (+) and negative (-) marks disposed on the marking surface at opposite ends of the scale units. Each scale unit has a central reference scale, several positive distance scales arranged at equal intervals from the reference scale towards the positive marks, and several negative distance scales arranged at equal intervals from the reference scale towards the negative marks. The vernier includes a vernier body movably mounted on the scale body, and indicator lines disposed on the vernier body and correspondingly pointing to the scale units.
[0006] The laser centering device calibrator of this utility model has a vernier body with a through hole for the scale to pass through, and a window that connects to the through hole and can correspondingly display a portion of the scale unit. The indicator line is used to indicate the position located in the center of the window.
[0007] The calibrator of the laser centering device described in this utility model further includes a connecting member disposed at one end of the ruler body of the scale.
[0008] The corrector of the laser alignment device of this utility model is a magnet.

[0029] Before this utility model is described in detail, it should be noted that similar elements are represented by the same reference numerals in the following description.
[0030] See Figure 1 , Figure 2 and Figure 3The first embodiment of the laser alignment device of this utility model is suitable for installation on a transmission mechanism 9. The transmission mechanism 9 includes a first object 91 and a second object 92 located in front of it, and a connecting member 93 that connects the first object 91 and the second object 92. The first object 91 has a first surface 911, and the second object 92 has a second surface 921. Both the first surface 911 and the second surface 921 are located on the same side relative to the connecting member 93. The transmission mechanism 9 is, for example, but not limited to, a pulley system or a sprocket system. Both the first object 91 and the second object 92 are pulleys, and the connecting member 93 is a belt, chain, or rope. In this first embodiment, the transmission mechanism 9 is used for radial transmission, and both the first object 91 and the second object 92 are upright.
[0031] The laser alignment device includes a transmitter 1 and four correctors 2. It should be noted that the number of correctors 2 is not limited to four; depending on the actual needs, it can be one, two, three, etc.
[0032] The transmitter 1 includes a mounting base 11 disposed on the first surface 911 of the first object 91, three levels 12 respectively disposed on the mounting base 11, a connecting member 13 disposed on the mounting base 11, and a light-emitting element 14 mounted on the mounting base 11 and capable of emitting a laser beam forward.
[0033] The mounting base 11 includes two through surfaces 111 spaced apart front to back, two side surfaces 112 spaced apart and connected to the two sides of the through surfaces 111, an inner end surface 113 and an outer end surface 114 spaced apart and connected to the other two sides of the through surfaces 111, and a central hole 115 axially communicating with the through surfaces 111. The inner end surface 113 rests against the first surface 911. The level 12 is respectively disposed on the two side surfaces 112 and the outer end surface 114. Each level 12 has a bubble 121 that can move 360° and can be used to measure whether it is level, but its structure is not the focus of this utility model, so it will not be described in detail here. It should be noted that the number of level 12 is not limited to three; it can be one, two, four, etc., depending on actual needs. The connecting element 13 is a magnet, disposed on the inner end face 113 of the mounting base 11. It can be detached and magnetically attracted to the first surface 911, so that the mounting base 11 is positioned on the first object 91, but its structure is not limited to this. The light-emitting element 14 passes through the axial hole 115 of the mounting base 11 and can emit a laser beam forward.
[0034] The calibrators 2 are angularly spaced from each other on the second surface 921 of the second object 92. Each calibrator 2 includes a scale 21, a vernier 22, and a connecting member 23. The scale 21 includes a scale body 212 having a marking surface 211, scale units 213 disposed along the length direction of the scale body 212 on the marking surface 211, and positive marks 214 (+) and negative marks 215 (-) disposed on the marking surface 211 and located at two opposite ends of the scale units 213. The marking surface 211 is flat and can be illuminated by the projected laser beam to display light spots. The scale unit 213 has a central reference scale 216, several positive distance scales 217 arranged at equal intervals from the reference scale 216 toward the positive mark 214, and several negative distance scales 218 arranged at equal intervals from the reference scale 216 toward the negative mark 215. The positive symbol 214 and the negative symbol 215 represent the property symbols of positive and negative numbers, respectively.
[0035] The vernier 22 includes a vernier body 221 movably mounted on the ruler body 212 of the scale 21, and an indicator line 222 disposed on the vernier body 221 and correspondingly pointing to the scale unit 213. The vernier body 221 has a through hole 223 through which the scale 21 passes, and a window 224 communicating with the through hole 223 and correspondingly displaying a portion of the scale unit 213. The indicator line 222 is used to indicate the position located at the center of the window 224.
[0036] The connector 23 is a magnet, which is disposed at one end of the ruler body 212 of the scale 21. It can be detachably magnetically attracted to the second surface 921, so that the ruler body 212 is positioned on the second object 92, but its structure is not limited to this.
[0037] Furthermore, the mounting base 11, the scale 21, and the vernier 22 of this first embodiment can be subjected to aluminum alloy anodizing treatment. The formation of the oxide layer is controlled by electrochemical methods to prevent further oxidation of the aluminum material. At the same time, it can increase the mechanical properties of the surface, making it less susceptible to corrosion and wear, and can provide a surface finishing effect. The aluminum alloy anodizing treatment is a known technology, so it will not be described in detail here.
[0038] See Figure 1 , Figure 4 and Figure 5During adjustment and calibration, first measure the difference in rim width between the first object 91 and the second object 92, that is, measure the first distance W1 between the first surface 911 and the side of the linkage 93, and measure the second distance W2 between the second surface 921 and the side of the linkage 93. Calculate the difference T = W1 - W2 between the first distance W1 and the second distance W2. This difference T is equal to the difference in rim width between the first object 91 and the second object 92. Next, adjust the alignment point of each calibrator 2, that is, move the vernier 22 on the scale 21 so that the position indicated by the indicator line 222 is aligned with the scale position equal to the difference T. Figure 4 If the difference T = 0 mm, then the vernier 22 is moved so that the indicator line 222 is aligned with the "0" of the reference scale 216. Then, the calibrators 2 are magnetically attached to the second surface 921 of the second object 92 at angular intervals. The transmitter 1 is magnetically attached to the first surface 911 of the first object 91 and the transmitter 1 is turned on to emit the laser beam. If it shines on the "0" of the pre-memorized reference scale 216, it can be known that the first object 91 and the second object 92 are truly parallel.
[0039] See Figure 6 and Figure 7 If the difference in rim width between the first object 91 and the second object 92 is a positive value, for example, the difference T = W1 - W2 is positive 10 mm, then the vernier 22 is moved towards the positive mark 214 to the "10" position of the positive distance scale 217. When the laser beam emitted by the transmitter 1 illuminates the pre-memorized "10" position of the positive distance scale 217, it can be determined that the first object 91 and the second object 92 are truly parallel.
[0040] See Figure 8 and Figure 9 If the difference in rim width between the first object 91 and the second object 92 is negative, for example, the difference T = W1 - W2 is -10 mm, then the vernier 22 is moved towards the negative mark 215 to the "10" position of the negative distance scale 218. When the laser beam emitted by the transmitter 1 illuminates the pre-memorized "10" position of the negative distance scale 218, it can be determined that the first object 91 and the second object 92 are truly parallel.
[0041] See Figure 10 The second embodiment of the laser alignment device of this utility model is substantially the same as the first embodiment, except that: in this second embodiment, the transmission mechanism 9 is a vertical transmission application, and both the first object 91 and the second object 92 are placed horizontally. The transmitter 1 is also mounted on the first object 91, and the corrector 2 is also mounted on the second object 92.
[0042] See Figure 11 The third embodiment of the laser alignment device of this utility model is substantially the same as the second embodiment, except that the side surfaces 112 of the mounting base 11 are spaced apart and symmetrical in shape. Each side surface 112 is a concave-convex curved surface and has a concave waisted portion 116 that is recessed toward the other side surface 112. The concave waisted portion 116 of this third embodiment is U-shaped, but its shape is not limited thereto. The design of the side surfaces 112 makes the mounting base 11 easy to grip and hold, and convenient to use.
[0043] In summary, the laser centering device and its calibrator 2 of this utility model, with the setting of the positive mark 214 and the negative mark 215 on the scale 21, can easily determine the direction of movement of the vernier 22, so as to avoid miscalculation or misjudgment. It is quite practical and can indeed achieve the purpose of this utility model.

Equivalent variations made based on the contents of the claims and description of this utility model should also be covered by the scope of the claims of this utility model.
