Description

Technical Field

[0001] This utility model relates to a micrometer measuring tool assembly tool, specifically a small micrometer measuring anvil bonding clamp. Background Technology

[0002] Small micrometers are often used to measure distances by placing the micrometer screw and the measuring anvil in a small gap. The diameter of the measuring ends of both are generally 1.5mm, 2mm, and 3mm, and their length extending out of the "U"-shaped frame is not less than 5mm.

[0003] Because the measuring end diameter is small, if the measuring end of the micrometer screw and the anvil is significantly misaligned, it will cause interference between the measuring end and the gap, making it impossible to perform the measurement and resulting in a large measurement error, especially when measuring the outer diameter.

[0004] Therefore, during the assembly and manufacturing of small micrometers, it is necessary to ensure that the misalignment of the two measuring ends of the micrometer screw and the anvil is within the specified range. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model proposes a small micrometer anvil bonding clamp that ensures the measuring end of the anvil and the measuring end of the micrometer screw are not misaligned during installation.

[0006] The technical solution for a small micrometer anvil bonding fixture that can solve the problems of existing technologies is as follows:

[0007] 1. A base having a length direction of left and right, wherein a through "V" shaped positioning groove is coaxially formed inside the base.

[0008] 2. The front or rear part of the substrate is provided with a disassembly groove that communicates with the "V" shaped positioning groove.

[0009] 3. The top of the left and right ends of the base are respectively screwed with fastening screws that communicate with the "V" shaped positioning groove.

[0010] Furthermore, the “V”-shaped positioning groove includes a square groove and a “V”-shaped groove that are connected at the top and bottom, and the disassembly groove connects the upper part of the square groove and the “V”-shaped groove.

[0011] Furthermore, a cleaning slot is provided on the top of the base between the left and right screw mounting positions, which communicates with the square groove. The "V" shaped groove can be observed and cleaned through the cleaning slot.

[0012] Typically, the substrate is preferably cylindrical.

[0013] The beneficial effects of this utility model are:

[0014] The small micrometer anvil bonding fixture of this utility model can ensure that the measuring end of the anvil and the measuring end of the micrometer screw are coaxial and not misaligned during the assembly and manufacturing process of the small micrometer. It has the characteristics of being simple to use, reliable, efficient and easy to maintain. Attached Figure Description

[0019] The technical solution of this utility model will be further described below with reference to the embodiments shown in the accompanying drawings.

[0020] This utility model relates to a micrometer anvil bonding fixture, comprising a cylindrical base 1, the length direction of which is left and right. A V-shaped positioning groove 11 is coaxially formed inside the base 1, the V-shaped positioning groove 11 extending through the left and right ends of the base 1. Figure 1 , Figure 2 As shown.

[0021] The vertical centerline of the "V"-shaped positioning groove 11 passes through the axis of the base 1. The "V"-shaped positioning groove 11 includes an upper rectangular groove and a lower "V"-shaped groove that are connected. A disassembly groove 12 is provided inwardly at the front of the base 1, connecting the upper parts of the rectangular groove and the "V"-shaped groove. A notch is cut inwardly at the top of the base 1 to form a cleaning groove 13, which connects to the rectangular groove, exposing the "V"-shaped groove. The ends of the base 1 on the left and right sides of the cleaning groove 13 (not cut) are screw mounting positions. Each screw mounting position has a threaded hole 2 communicating with the rectangular groove at its top. Figure 1 , Figure 2 As shown.

[0022] The method of using this utility model is as follows:

[0023] 1. Place the left measuring end of the micrometer screw 3 (which is already installed on the right end of the "U"-shaped ruler 6) into the "V"-shaped positioning groove 11 on the right end of the base 1, and tighten the fastening screws at the corresponding ends to fix the base 1 onto the micrometer screw 3.

[0024] 2. Place the measuring end on the right side of the anvil 4 (with the same diameter as the measuring end of the micrometer screw 3) into the “V” shaped positioning groove 11 on the left side of the base 1, and tighten the fastening screws at the corresponding ends to fix the anvil 4 on the base 1, thereby achieving coaxial installation (without misalignment) of the two measuring ends of the anvil 4 and the micrometer screw 3.

[0025] 3. Rotate the micrometer screw 3 to make it rotate around the axis to achieve feeding, thereby driving the base 1 and the anvil 4 to rotate together and move forward towards the anvil hole 5 opened at the left end of the "U" shaped ruler 6. The anvil hole 5 is coated with glue beforehand.

[0026] 4. Continue to rotate the micrometer screw 3 and screw the positioning end on the left side of the anvil 4 into the anvil hole 5. After the glue has initially cured, loosen the set screws on the left and right ends of the substrate 1. The substrate 1 can then be easily removed from the two measuring ends of the micrometer screw 3 and the anvil 4 through the disassembly groove 12 (the groove width is slightly larger than the diameter of the measuring ends of both).
