Description

Technical Field

[0001] The utility model relates to the field of crystal processing, in particular to a parallelism detection device. Background Art

[0002] When cutting glass or crystal into square pieces, special reasons may necessitate two separate cuts: first, into long strips, then re-plate and cut perpendicularly once. To meet the required perpendicularity tolerances for the square pieces, a vertical guide is used to wax the glass strips or crystals. This involves pressing the glass strips or crystals together, ensuring the sides of the guide are parallel to the strips or crystals, and then securing them with wax. After cooling and solidification, the parallelism between the tool and the glass strips or crystals is measured to confirm that the adhesive meets the cutting requirements.

[0003] There are many ways to confirm parallelism, such as the knife-edge ruler light test, which can only make a rough subjective judgment and cannot accurately measure; there is also a projector, which is affected by light transmittance and surface blur and has low accuracy; a more advanced method is to use three-coordinate measuring instruments for measurement, which is extremely expensive and unaffordable for ordinary companies. It also requires specialized personnel and environment, is difficult to detect, and has low measurement efficiency.

[0004] In the existing technology, either the measurement is inaccurate or the cost is high, and there is no method that takes into account cost, efficiency and accuracy. Utility Model Content

[0005] In view of the above-mentioned deficiencies in the prior art, the purpose of the present invention is to design a parallelism detection device that can achieve accurate measurement, improve efficiency and save costs.

[0006] In order to achieve the above-mentioned purpose, the technical solution provided by the present invention is as follows: a parallelism detection device includes a base, a vertical rod, a connecting block, a parallel plate, and a trapezoidal support body. The vertical rod is inserted into the opening on the base and fixed by the base fixing screw; the vertical rod is connected to the connecting block, and a through-hole is provided in the middle of the connecting block in the vertical direction, and the vertical rod passes through the through-hole. The connecting block is also provided with a middle opening in the horizontal direction, and the dial indicator penetrates the middle opening in the horizontal direction and is fixed on the connecting block. The parallel plate is placed on the base, and a trapezoidal support body is provided on the side that abuts against the vertical rod, and its shape is wide at the top and narrow at the bottom. The trapezoidal support body is located below the connecting block. When in use, the upper edge of the trapezoidal support body contacts the side of the standard verticality support body in a linear manner, reducing the size of the contact surface and improving the detection accuracy.

[0007] Furthermore, the connecting block moves up and down on the vertical rod to adjust the height, and is fixed to the vertical rod with a connecting block fixing piece to maintain stability.

[0008] Preferably, the dial indicator measuring head is fixed to the dial indicator via a screw thread.

[0009] Preferably, the area of the parallel plate is larger than the base, and the parallel plate is bonded to the surface of the base with cold glue, so it has good upper and lower parallelism, a wear-resistant surface, can well protect the base, and is easy to replace.

[0010] Preferably, the vertical rods are two aluminum rods.

[0011] The main features of the structure of this utility model are:

[0012] 1. Accurately measure the parallelism of crystals or glass secondary cutting adhesives with high precision. The verticality tolerance after cutting can be calculated. 2. Fast test speed and high efficiency. Quickly determine whether the upper plate is qualified or not to avoid crooked cutting of samples. 3. The device is inexpensive and realizes low-cost production.

[0018] In order to better understand the technical solution of the present invention, the embodiments of the present invention are described in detail below in conjunction with specific embodiments. It should be understood that the embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0019] The terms used in the embodiments of this invention are for the purpose of describing specific embodiments only and are not intended to limit the invention. The singular forms "a," "the," and "the" used in the embodiments of this invention and the appended claims are intended to include the plural forms, unless the context clearly indicates otherwise. The test materials used in this invention are all commonly available commercially.

[0020] Reference Figures 1 to 4The parallelism detection device shown in the figure comprises a base 1, a vertical rod 2, a connecting block 3, a parallel plate 4, and a trapezoidal support body 5.

[0021] The base 1 serves as a load-bearing fixture, with an opening on its end face. A vertical rod 2 is inserted into the opening and secured via a base fixing screw 9. The vertical rod 2 is connected to a connecting block 3, which has a vertical hole in the middle. The vertical rod 2 extends through this hole. The connecting block 3 can be moved up and down on the vertical rod 2 to adjust its height and is secured to the vertical rod 2 with a connecting block fixing 10 for stability. The connecting block 3 also has a horizontal hole in the middle. The crossbar of the dial indicator 6 extends through the hole and is locked to the connecting block 3 via a dial indicator fixing screw 8. One end of the dial indicator 6 contains a measuring head 7 for measuring samples, which is fixed to the dial indicator 6 via a screw thread. The measuring head 7 can be flexibly replaced according to the actual situation during measurement. Preferably, the vertical rods 2 are two aluminum rods.

[0022] The base 1 is provided with a parallel plate 4, which has an area larger than the base 1. The parallel plate 4 is bonded to the surface of the base 1 with cold glue, has good upper and lower parallelism, is wear-resistant, can well protect the base 1, and is easy to replace.

[0023] A trapezoidal support 5, wide at the top and narrow at the bottom, is installed on the side where the parallel plate 4 abuts the vertical rod 2. Positioned below the connecting block 3, the upper edge 11 of the support 5 linearly contacts the side of a standard verticality support (not shown), minimizing the contact surface and improving detection accuracy. The angle between adjacent reference surfaces of the verticality support is precisely 90 degrees, ensuring that the sample being tested is perpendicular to the cutting line.

[0024] Specific implementation method: Use wax to stick the crystal sheet or glass strip to the side of the verticality support, and place the whole on the parallel plate 4, close to the trapezoidal support 5 and the measuring head 7. According to the actual height of the sample and the tooling, adjust the height of the connecting block 3 through the connecting block fixing 10 so that the measuring head 7 is at the same level as the sample to be measured, and at the same time, the upper edge 11 of the trapezoidal support 5 is against the verticality support. Then adjust the horizontal position of the dial indicator 6 so that the measuring head 7 is in contact with the sample to be measured and return to zero. Move the verticality support laterally, keeping it against the upper edge 11, and check the maximum value of the pointer of the dial indicator 6 to read the parallelism value of the sample. If the deviation of the parallelism value of the sample during the lateral movement is within the standard requirements, it is determined that the sample is parallel to one side of the verticality support and meets the cutting requirements. Otherwise, re-stick the wax on the plate and repeat the above steps until the test is completed. The parallelism of the sample can also be measured using a multi-point measurement method.

[0025] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
