Abstract
Description
Technical Field
[0001] This utility model relates to the field of auxiliary fixtures for wire cutting equipment, and in particular to a planar calibration device. Background Technology
[0002] Diamond wire cutting machines are efficient and precise cutting tools, mainly used for cutting various hard materials such as glass, ceramics, monocrystalline silicon, and polycrystalline silicon. One current processing task involves face cutting of glass sheets. Therefore, it is necessary to ensure that the plane of the glass sheet is aligned with the diamond wire (cutting surface); otherwise, deviations will occur, leading to cutting failure.
[0003] Generally, glass sheets are mounted on fixtures, and multiple sheets are cut together with the fixtures on the cutting machine. To ensure that the processing accuracy meets the requirements, there are two common methods: one is to measure the accuracy of the installation position of the glass sheets on the fixtures before cutting, and only cut them after the accuracy is met; the other is to measure the installation accuracy of the glass sheets with a laser instrument or other instruments after the fixtures are fixed on the cutting machine, and only cut them after the accuracy is met. However, neither of these methods can guarantee that the glass sheets are flush with the diamond wire, because there may be errors in the installation position of the fixtures, or errors in the machining of the guide wheels of the multi-wire cutting machine, etc. The existence of these uncontrollable factors makes the accuracy problem of this type of processing task a difficult challenge in the industry.
[0004] In view of this, the present invention provides a new solution to the above problems. Utility Model Content

[0034] The present invention will be further described in detail below with reference to the accompanying drawings.
[0035] Please see Figure 1-7 This embodiment provides a planar calibration device 100, which is applied to a diamond wire cutting equipment and is used to quickly measure whether the installation accuracy of the workpiece to be tested meets the standard.
[0036] Specifically, in this embodiment, the workpiece to be tested is a glass sheet, and the processing task is to perform surface cutting along the glass plane to cut multiple thin glass sheets from the workpiece. The diamond wire cutting equipment has two guide wheels 10 on the same horizontal plane, with diamond wire (not shown) wound on the guide wheels 10. The diamond wire is tensioned by a tensioning mechanism, and the surface of the guide wheels 10 has wire grooves 11 to separate the diamond wire and prevent it from slipping. For example, in this embodiment, the cross-section of the wire grooves 11 is V-shaped; the guide wheels 10 in this embodiment are provided with three wire grooves 11 per group, with a large distance between the groups.
[0037] The plane calibration device 100 includes a support 20 and a dial indicator 30.
[0038] The bracket 20 has a reference surface 21, which has extremely high flatness. At the bottom of each end of the bracket 20, there is a retaining tooth 22. The shape and dimensions of the retaining tooth 22 are consistent with the shape and dimensions of the wire slot 11, i.e., V-shaped, for embedding into the wire slot 11 during use (e.g., ...). Figure 7 (As shown). When the two locking teeth 22 are respectively embedded in the corresponding wire slots 11, the reference surface 21 of the bracket 20 can be effectively fixed at a position parallel to the cutting plane. Specifically, the wire slots 11 at the same position of the two guide wheels 10 can define a diamond wire and the corresponding cutting plane. By cooperating with the locking teeth 22, the position of the two locking teeth 22 can be determined, thereby ensuring that the reference surface 21 is parallel to the cutting plane.
[0039] The dial indicator 30 is used in conjunction with the support 20. The structure and function of the dial indicator 30 itself are existing technology; this embodiment only describes its key components. In use, the probe 31 of the dial indicator 30 extends perpendicularly through the reference surface 21 to the vicinity of the surface of the workpiece being measured. During measurement, the dial indicator 30 translates along the reference surface 21, for example, from the left to the right of the glass slide. If there is an offset between the glass slide and the cutting plane, the reading obtained by the dial indicator 30 will show this deviation; if the glass slide is parallel to the cutting plane, the reading obtained by the dial indicator 30 will also show this parallel relationship.
[0040] Therefore, simply moving the dial indicator 30 along the reference plane 21 is sufficient to determine whether the plane of the glass sheet under test is parallel to the cutting plane. The entire plane calibration device 100 has a simple structure and is easy to operate. Furthermore, the plane calibration device 100 measures the state of the glass sheet after it is mounted on the machine, which can actually reflect the true installation accuracy of the glass sheet. Once a positional deviation is measured, the machine is stopped and adjusted until the installation accuracy meets the standard, thus ensuring the final processing accuracy.
[0041] Please continue reading. Figure 1 and Figure 2 In this embodiment, the bracket 20 includes a crossbeam 23 and two positioning blocks 24. The two positioning blocks 24 are respectively connected to the bottom ends of the crossbeam 23. Therefore, the locking teeth 22 are correspondingly arranged on the bottom surface of the positioning blocks 24. One side of the crossbeam 23 is set as a reference surface 21. The bracket 20 is configured as described above to match diamond wire cutting equipment of different specifications. Because the spacing between the two guide wheels 10 is different in different cutting equipment, it is only necessary to set the spacing between the two positioning blocks 24 to the spacing between the two guide wheels 10, and then connect them to the crossbeam 23 to adapt to the cutting equipment. Each positioning block 24 is detachably connected to the bottom of the crossbeam 23, such as by bolt connection or adhesive bonding.
[0042] In a preferred embodiment, the top surface of the positioning block 24 is also provided with a slot (not shown in the figure), and the bottom of the crossbeam 23 fits into the slot. When manufacturing the slot and the crossbeam 23, it is necessary to ensure that all surfaces are horizontally and vertically aligned, which is relatively easy to achieve in existing industrial processing. Therefore, the positioning block 24 with the slot can slide relative to the crossbeam 23 and be flexibly positioned in a suitable location to accommodate different guide wheel 10 spacings.
[0043] In this embodiment, a long, narrow groove 231 is provided in the middle of the crossbeam 23, extending through both sides of the crossbeam 23. The groove 231 allows the probe 31 of the dial indicator 30 to pass through the crossbeam 23. During translation along the reference surface 21, the dial indicator 30 actually moves along the groove 231. It should be noted that the dial indicator 30 must not detach from the reference surface 21 during measurement; the distance between the end of the probe 31 and the reference surface 21 must remain constant, using this as a reference for measuring the plane to be measured.
[0044] Furthermore, to make the translation process of the dial indicator 30 smoother and the operation more convenient, a slider 40 is also provided. The slider 40 itself can be shaped like a disc, rectangle, etc. The slider 40 is fixedly connected to the bushing 32 of the dial indicator 30. Therefore, the slider 40, the bushing 32, and the housing of the dial indicator 30 are integrated. The probe 31 is actually positioned perpendicularly through the slider 40, and the probe 31 itself can extend and retract along its axis. With the addition of the slider 40, by ensuring that one side of the slider 40 always remains in contact with the reference surface 21, it can be ensured that the dial indicator 30 will not detach from the reference surface 21 during the translation process.
[0045] More specifically, the crossbeam 23 is made of a metal material, such as stainless steel. A magnetic element, such as a magnet 50, is also provided between the slider 40 and the crossbeam 23. The magnetic attraction keeps the slider 40 in contact with the reference surface 21, preventing it from detaching. In this embodiment, four magnets 50 are provided, and four mounting holes (not shown in the figure) are opened on the side of the slider 40 facing the reference surface 21. The magnets 50 are fixed in the mounting holes, and the four magnets 50 are evenly distributed on the slider 50. By using the magnets 50 to hold the crossbeam 23 in place, the operator can concentrate the force mainly on the process of moving the dial indicator 30, without having to consciously maintain the contact between the slider 40 and the reference surface 21, thus making the measurement process simpler and more convenient.
[0046] It is worth mentioning that the outer surfaces of the four magnet blocks 50 are flush with the surface of the positioning holes, which ensures stable magnetic attraction and avoids errors in the measurement process.
[0047] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
