[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments 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 creative work are within the scope of protection of the present invention.
[0026] The object of the present invention is to provide a floating measuring tool for efficiently measuring the surface depth of equipment.
[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.
[0028] Reference Figure 1 The present embodiment provides a floating measuring tool, including a mounting seat, a locking assembly 6, a slider 7, a micrometer 10 and a probe assembly.
[0029] The mounting base includes a base 1 and a cover plate 11, and the base 1 is fixedly connected to the cover plate 11. The locking assembly 6 is installed on the base 1, and is used to lock the workpiece to be measured on the base 1. The slider 7 is installed on the base 1 along a straight line. The micrometer 10 has a body and a measuring end rotatably installed on the body. The measuring end passes through the cover plate 11, and the measuring end is fixedly connected to the first side of the slider 7. The first end of the probe assembly is fixedly connected to the second side of the slider 7, and the second end of the probe assembly is used to contact the workpiece to be measured. The probe assembly includes a floating probe 2 so that the probe assembly can be extended and retracted.
[0030] The working principle of the floating measuring tool in this embodiment is as follows:
[0031] The locking assembly 6 locks the workpiece to be measured on the base 1, and the second end of the probe assembly contacts the surface of the workpiece to be measured. Under the push of the workpiece to be measured, the probe assembly and the slider 7 slide toward the micrometer 10 together, and the length of the probe assembly itself is shortened. By rotating the body of the micrometer 10 so that the micrometer 10 fits the cover 11, the distance between the slider 7 and the cover 11 can be measured.
[0032] The probe assembly and the workpiece to be measured are electrically connected to the two poles of the external DC power supply to form a DC circuit, and the DC circuit is connected in series with a buzzer. In the initial state, the first end and the second end of the probe assembly are not electrically conductive. As the slider 7 moves upward, the second end of the probe assembly contacts the workpiece to be measured, and then the probe assembly is gradually compressed. The buzzer emits a buzzer when the DC circuit is conductive, and the length of the probe assembly is the initial conductive length, which is a known quantity measured in advance.
[0033] Combined with the distance between the slider 7 and the cover plate 11, and the initial conduction length of the probe assembly, the distance between the second end of the probe assembly and the cover plate 11 can be calculated. Since the base 1 and the cover plate 11 are fixedly connected, the length of the second end of the probe assembly extending from the base 1 can be further calculated according to the relative position and size of the base 1 and the cover plate 11. This length can be regarded as the surface depth of the workpiece to be measured.
[0034] The above-mentioned measuring method combines the micrometer 10 with the probe assembly, which not only simplifies the measuring operation but also improves the accuracy of the measuring result.
[0035] The base 1 and the cover plate 11 can be fixedly connected by screws 12 to facilitate disassembly and storage.
[0036] As a possible example, in this embodiment, a groove is provided on the base 1, and the cover plate 11 covers the notch of the groove. The slider 7 slides between the bottom of the groove and the cover plate 11. The base 1 and the cover plate 11 limit the sliding position of the slider 7 from both ends.
[0037] As a possible example, in this embodiment, the floating measuring fixture further includes a guide pin 3, the two ends of which are fixedly connected to the base 1 and the cover plate 11 respectively, and the guide pin 3 slides through the slider 7, and the measuring end is parallel to the guide pin 3. There are multiple guide pins 3 to limit the rotation of the slider 7. It is understandable that those skilled in the art can also limit the rotation of the slider 7 by limiting the contact between the slider 7 and the side wall of the groove.
[0038] As a possible example, in this embodiment, there are multiple probe assemblies, each of which is parallel to the guide pin 3, and the first ends of the multiple probe assemblies are located in a plane perpendicular to the guide pin 3. By providing multiple probe assemblies, multiple positions of the workpiece to be measured can be measured simultaneously, thereby further improving the measurement efficiency.
[0039] In actual use, the currents of multiple probe assemblies may not be turned on at the same time. For the probe assembly that is turned on first, the depth of its corresponding position is measured first, and then as the slider 7 continues to move upward, the probe assembly that is turned on first continues to be compressed, and the remaining probe assemblies are turned on one after another.
[0040] As a possible example, in this embodiment, the locking assembly 6 includes a slide bar, a limit block 1 9, a limit block 2 14, a locking block 13 and a compression spring 8. The slide bar slides through the base 1. From the first end to the second end of the slide bar, the limit block 1 9, the limit block 2 14 and the locking block 13 are arranged in sequence. The limit block 1 9 is located on the side of the base 1 close to the micrometer 10, the limit block 2 14 and the locking block 13 are located on the side of the base 1 away from the micrometer 10, and the compression spring 8 is located between the limit block 1 9 and the base 1. The locking block 13 is arranged to float at one end away from the base 1. When the locking block 13 moves upward and slides in contact with the workpiece to be measured, the locking block 13 is elastically deformed to avoid the workpiece to be measured. After the locking block 13 moves to the top of the workpiece to be measured, the locking block 13 is elastically reset. At this time, the lower end surface of the locking block 13 can press the workpiece to be measured down on the base to achieve the positioning of the workpiece to be measured.
[0041] The compression spring 8 applies a thrust to the limit block 1 9, so that the limit block 2 14 and the base 1 sandwich the edge of the workpiece to be measured, thereby positioning the workpiece to be measured. The number of locking assemblies 6 is preferably multiple, so that multiple positions of the workpiece to be measured can be locked and fixed at the same time. After the measurement is completed, the slide bar is pushed to shorten the length of the compression spring 8, and the distance between the limit block 2 14 and the base 1 is increased, thereby releasing the workpiece to be measured.
[0042] As a possible example, in this embodiment, the stopper 9 is a nut, and the stopper 9 is threadedly connected to the slide bar. By rotating the stopper 9, the relative position of the stopper 9 and the slide bar can be adjusted to adapt to workpieces of different thicknesses to be measured.
[0043] As a possible example, in this embodiment, the locking block 13 is wedge-shaped, and the tip is facing away from the micrometer 10 (i.e. Figure 1 The locking block 13 of this shape is conducive to reducing the resistance when elastically avoiding the workpiece to be measured.
[0044] As a possible example, in this embodiment, a countersunk hole is provided on the side of the base 1 facing away from the micrometer 10, and the second limit block 14 is located in the countersunk hole. By providing the countersunk hole, the second limit block 14 can be received in the countersunk hole, so that the workpiece to be measured is in direct contact with the base 1, which is convenient for locking and fixing the workpiece to be measured.
[0045] As a possible example, in this embodiment, the probe assembly further includes a sleeve 15, a wool button 4 and an ejector pin 5. The ejector pin 5 is located at a first end of the sleeve 15, and one end of the ejector pin 5 extends into the sleeve 15. The wool button 4 is located in the sleeve 15 and is conductively connected to the ejector pin 5 and the floating probe 2.
[0046] The sleeve 15 is made of insulating material. In the initial state of the probe assembly, the floating probe 2 does not contact the hair button 4, so the first end and the second end of the probe assembly are not electrically connected. When the floating probe 2 contacts the workpiece to be measured, as the probe assembly is compressed, the floating probe 2 gradually approaches the hair button 4. At the moment when the floating probe 2 contacts the hair button 4, the first end and the second end of the probe assembly are electrically connected, and the length of the probe assembly is the initial conductive length.
[0047] Exemplarily, the base 1 is made of insulating material, and the cover 11, micrometer 10, and slider 7 are made of conductive material. One pole of the external DC power supply is electrically connected to the cover 11, and is electrically connected to the multiple probe assemblies through the micrometer 10 and the slider 7, so that the multiple probe assemblies are connected in parallel. There is one buzzer, and each probe assembly triggers a buzzer when it is electrically conductive.
[0048] As a possible example, in this embodiment, the base 1 has a cylinder 16 on the side away from the micrometer 10, and the probe assembly passes through the cylinder 16 and is parallel to the axis of the cylinder 16. The cylinder 16 has a stepped surface on the inner side, and the upper end of the sleeve 15 contacts the stepped surface for position limiting, and the lower end of the sleeve 15 contacts the upper surface of the slider 7 for position limiting.
[0049] As a possible example, in this embodiment, the probe assembly further includes an inner conductor located in the sleeve 15 , and the inner conductor is located between the wool button 4 and the ejector pin 5 or between the wool button 4 and the floating probe 2 .
[0050] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
