Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of precision machinery, and in particular relates to a precision machinery calibration device. Background Art
[0002] Precision machinery generally refers to equipment and devices used to produce and measure precision quantities, including observation, monitoring, measurement, recording, transmission, analysis, processing and control of precision quantities. Three-dimensional coordinate measuring machines are widely used in machinery, electronics, instrumentation, plastics and other industries. Three-dimensional coordinate measuring machines are one of the most effective methods for measuring and obtaining dimensional data. Before measuring, the three-dimensional coordinate measuring machine must be calibrated. The three-dimensional standard ball is used as a reference ball for calibrating the three-dimensional measuring needle. The standard ball is related to the accuracy of the three-dimensional measuring needle, so the accuracy requirements of the standard ball are very high. Its material is generally made of ceramics, glass, tungsten carbide and other materials. Ceramic standard balls are more popular because of their relatively low cost, low thermal expansion coefficient and high hardness.
[0003] Due to the material characteristics of the three-coordinate standard ball in the prior art, it may fall accidentally during use, causing the standard ball to break or scratch. When stored, dust is easily accumulated on the surface of the ball. These situations will not only cause economic losses, but also affect the calibration accuracy of the three-coordinate measuring machine, resulting in unqualified products. Utility Model Content

It should be understood that the following text is only used to describe one or several specific implementations of the utility model, and does not strictly limit the protection scope of the specific request of the utility model.
[0018] like Figure 2-3 As shown, a precision mechanical calibration device includes a fixed seat 1 and a sleeve 2, a screw groove 107 is penetrated at one end of the fixed seat 1, a standard ball 108 is threadedly connected to the top of the fixed seat 1 and one side of the screw groove 107, a bolt 101 is threadedly connected to the inner wall of the screw groove 107, a rotating handle 102 is fixedly connected to the top of the bolt 101, a ring 104 is movably sleeved on the outer wall of the rotating handle 102, a clamping ring 103 is fixedly connected to the outer wall of the rotating handle 102 and located above the ring 104, a connecting rod 105 is symmetrically fixedly connected to one side of the ring 104, the ring 104 is fixedly connected to the second ring 106 through the connecting rod 105, the second ring 106 is movably sleeved on the outside of the standard ball 108, and connecting plates 109 are symmetrically fixedly connected to both ends of the second ring 106.
[0019] According to the above structure, rotating handle 102 drives bolt 101 to move spirally in screw groove 107. When bolt 101 moves downward to fix fixing seat 1, it drives ferrule 104 and connecting rod 105 to move downward together. Clamping ring 103 blocks and limits ferrule 104. Connecting rod 105 drives ferrule 2 106 and connecting plate 109 to move downward together.
[0020] Refer to the attached Figure 1-3 The top of the fixed seat 1 and the two sides of the standard ball 108 are symmetrically fixedly connected with vertical rods 205, the second ring 106 is slidably connected to the vertical rods 205, one end of the two vertical rods 205 and the outside of the standard ball 108 are jointly fixedly connected with a fixing frame 203, the jacket 2 is symmetrically rotatably arranged on both sides of the standard ball 108, the inner wall of the jacket 2 is fixedly connected with a protective soft sleeve 201, the bottom of the jacket 2 is symmetrically fixedly connected with a rotating rod 1 202, the two rotating rods 1 202 located on the same side are hinged to each other, and the two jackets 2 are hingedly connected to the fixing frame 203 through the rotating rod 1 202, one end of the rotating rod 1 202 is hingedly connected to the rotating rod 2 204, and the two rotating rods 204 located on the same side are hingedly connected to the connecting plate 109.
[0021] According to the above structure, when the second ring 106 drives the connecting plate 109 to move, it drives the second rotating rod 204 and the first rotating rod 202 to rotate in an articulated manner, and the vertical rod 205 and the fixed frame 203 provide support for the rotation of the first rotating rod 202. When the first rotating rod 202 rotates, it drives the jacket 2 and the protective soft sleeve 201 to separate from the standard ball 108, so that the standard ball 108 is exposed. After the calibration work is completed, the rotating handle 102 is twisted through the above steps to move the bolt 101 upward, so that the two jackets 2 are abutted and closed, and the protective soft sleeve 201 is close to the surface of the standard ball 108 to protect it; the utility model can open the jacket 2 while the fixed seat 1 is fixed for calibration, which is convenient for the calibration of the striker and the standard ball 108.

[0022] The working principle of the utility model is as follows: rotating the rotating handle 102 drives the bolt 101 to move spirally in the screw groove 107. When the bolt 101 moves downward to fix the fixing seat 1, it drives the ring 104 and the connecting rod 105 to move downward together, and the clamping ring 103 blocks and limits the ring 104, and the connecting rod 105 drives the ring 2 106 and the connecting plate 109 to move downward together; when the ring 2 106 drives the connecting plate 109 to move, it drives the rotating rod 204 and the rotating rod 1 202 to rotate hingedly, and the vertical rod 205 and the fixing frame 203 provide support for the rotation of the rotating rod 1 202. When the rotating rod 1 202 rotates, it drives the jacket 2 and the protective soft sleeve 201 to separate from the standard ball 108, so that the standard ball 108 is exposed. After the calibration work is completed, the rotating handle 102 is twisted through the above steps to move the bolt 101 upward, so that the two jackets 2 are abutted and closed, and the protective soft sleeve 201 is close to the surface of the standard ball 108 to protect it.
