[0024] In order to make the purpose, technical solutions and advantages of the utility model more clearly understood, the utility model is further described in detail below in conjunction with embodiments and drawings. The schematic implementation manner of the utility model and its description are only used to explain the utility model and are not intended to limit the utility model.

[0025] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0026] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined. The meaning of "several" is one or more, unless otherwise clearly and specifically defined.

[0027] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by the terms "up", "down", "front", "back", "left", "right", etc. are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0028] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" 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 an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] Since the Lp66 pad needs to be sent to large-scale equipment for polishing effect testing after polishing, and the testing takes a long time, the polishing results cannot be output in time, which ultimately leads to poor uniformity of the polishing effect and affects the polishing time and effect of the product.

[0030] In response to the above problems, Figure 1-3 As shown, the present invention provides a flatness detection jig, including a support platform 1, wherein the support platform 1 is triangular in shape, and two adjacent vertices are connected by an arc with an arc of 120°; a plurality of support columns 2 are connected to the bottom of the support platform 1; and a mounting hole 3 for a micrometer is provided on the support platform 1.

[0031] It should be noted that the flatness detection fixture provided by the present invention is not only suitable for detecting the surface flatness of Lp66 gaskets, but also suitable for other items that require surface detection.

[0032] When in use, the entire flatness detection jig is placed on the surface of the object to be detected. Specifically, the support column 2 is in contact with the surface of the object to be detected, the micrometer is installed in the mounting hole 3, and the flatness detection jig is pushed to move on the surface of the object. The pointer on the micrometer will move, and the flatness of the object surface can be determined by the direction of the micrometer pointer. The detection is fast and the result is accurate, which is conducive to timely adjustment of polishing and obtaining objects with good polishing effect.

[0033] The support platform 1 is set to be a triangle, and the arc is set to 120°, so that the flatness detection fixture has better stability. Generally, the number of support columns 2 is set to three, which are respectively distributed on the three vertices of the triangle.

[0034] In order to reduce the pressure on the support points, Figure 1 As shown, a steel ball is fixedly connected to the bottom of each support column 2. In practical application, the steel ball can be made of stainless steel with good wear resistance and rust resistance to extend the service life.

[0035] Since the flatness detection jig disclosed in the utility model needs to be pushed during use, in actual application, the support platform 1 is preferably made of a light and hard material, such as copper alloy and the like.

[0036] In actual use, Figure 1 As shown, the three corners of the support platform 1 are preferably blunt, that is, there are certain edges to avoid injury to the operator.

[0037] As a possible implementation, Figure 1-3 As shown, the lower part of the three vertices of the support platform 1 is integrally formed with a boss 4, and the support column 2 is connected to the boss 4. In actual use, the bottom of the support column 2 and the boss 4 can be welded into an integral shape, or can be threadedly connected. Specifically, one end of the support column 2 is set with an external thread, and the bottom of the boss 4 is provided with a threaded hole that matches the external thread on the support column 2. When in use, it is only necessary to screw the end of the support column 2 with the external thread into the threaded hole. The height of the boss 4 can be set accordingly according to the requirements of the actual application, mainly because the flatness detection fixture needs to meet a certain mechanical strength to avoid deformation during the pushing process and affect the flatness detection.

[0038] As a possible implementation, Figure 1 As shown, the mounting hole 3 may be provided with a threaded sleeve, and in actual use, the dial gauge only needs to be screwed into the threaded sleeve to achieve connection. This method is conducive to the rapid disassembly of the dial gauge.

[0039] As a possible implementation, in order to ensure that the flatness detection fixture has a good service life, the support column 2 is made of tungsten alloy. The height of the support column 2 is generally 15 to 20 cm, such as 15 cm, 16 cm, 17 cm, 18 cm, 19 cm, 20 cm and any value between any two values.

[0040] During actual manufacturing, the steel ball can be installed at the bottom of the support column 2 by embedding, which can be an interference fit. Glue can also be added on the basis of the interference fit to further increase the firmness.

[0041] The size of the support platform 1 is selected according to actual needs and does not fall within the scope of the present invention and is therefore not described in detail herein.

[0042] During actual manufacturing, the three corners of the support platform 1 can be manufactured separately, that is, the corner with three bosses 4 is formed in one piece, and the other parts of the support platform 1 are formed in one piece, and then the three corners and other parts are welded into a whole, or other connections are used to form a whole, for example, both are provided with connecting plates at their respective bottoms, and the connecting plates are connected by bolt assemblies.

[0043] In actual manufacturing, in order to reduce the mass of the entire flatness detection fixture and meet the hardness requirements at the same time, the support table 1 can be made of a combination of different materials. For example, the lower layer is made of a material with better hardness, and the upper layer is made of copper alloy. The upper and lower layers are then bonded or welded together.

[0044] Generally, the mounting hole 3 is arranged at the center of the support platform 1, so that the flatness detection jig can be easily pushed and moved from all angles, and the flatness detection jig can be prevented from flipping over during the pushing process, so that the flatness detection jig can be moved in the desired direction, saving detection time.

[0045] In practical applications, in order to make the mounting hole 3 suitable for different micrometers, the threaded sleeve can be set in different styles to meet the installation of different micrometers.

[0046] When the surface flatness of the gasket is Lp66, the threaded sleeve is a cylinder with external threads, and the external threads are threadedly connected to the connecting end of the micrometer. The cylinder and the mounting hole 3 can be threaded or embedded.

[0047] Steel balls are helpful to reduce the pressure at the supporting points; the 120° angle distribution makes the overall stability better; the support column 2 is made of black steel alloy, which has high support hardness and is not easy to rust; after multiple polishing tests, the use of flatness detection jigs can reduce the verification time of Lp66 gaskets, increase the production quantity of products, and help reduce costs and increase efficiency.

[0048] The utility model discloses a flatness detection jig. When it is used, it only needs to install the dial gauge in the installation hole, and push the whole flatness detection jig to move on the Lp66 pad. The dial gauge will immediately respond to the flatness of the position where the flatness detection jig is located, so the polishing of the Lp66 pad can be adjusted in time, so that the final polishing effect has good uniformity.

[0049] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above description is only the specific implementation method of the utility model and is not used to limit the protection scope of the utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
