Description

Technical Field

[0001] This utility model relates to an auxiliary tool for manufacturing micrometer measuring instruments, specifically a tool for bonding micrometer lead screws and anvils. Background Technology

[0002] The technical requirements for the measuring surface of a micrometer lead screw are: the measuring surface must maintain a perpendicularity of 2µm to the center of the lead screw; otherwise, the parallelism between the lead screw and the anvil will not meet the national standard requirements when the lead screw rotates.

[0003] Therefore, the flatness of the lead screw measuring surface and its perpendicularity to the center of the lead screw have always been the difficulties in the processing and manufacturing of micrometer products. Utility Model Content

[0004] To address the manufacturing difficulties of existing technologies, this utility model proposes an auxiliary tool for bonding micrometer lead screws and measuring anvils.

[0005] The micrometer lead screw and anvil bonding accessory that can solve the problems of existing technologies includes a "V" block, but differs in that it also includes a flat gauge block, wherein:

[0006] 1. The level of the “V” block is at least level 0.

[0007] 2. The flatness of the flat block is at least 0.2u.

[0008] 3. The flat gauge block is installed at one end of the "V" block, and the perpendicularity between the flat gauge block and the "V" block is at least 2u through adjustment. Attached Figure Description

[0010] Drawing number markings: 1. "V" block; 2. Flat gauge block; 3. Alloy probe; 4. Lead screw. Detailed Implementation

[0011] The technical solution of this utility model will be further described below with reference to the embodiments shown in the accompanying drawings.

[0012] This utility model relates to a micrometer screw rod and anvil bonding accessory for manufacturing micrometer screw rods, comprising a matching "V" block 1 and a flat gauge block 2. The flat gauge block 2 is mounted on the front end face of the "V" block 1 using a screw assembly. Figure 1 As shown.

[0013] The level of the "V"-shaped block 1 is at least level 0.

[0014] The flatness of the rear end face of the flat gauge block 2 is at least 0.2u.

[0015] Through installation and adjustment, the perpendicularity between the measuring surface of the flat gauge block 2 and the vertical plane of the center vertical plane of the "V" groove of the "V" block 1 is at least 2u.

[0016] The method of using this utility model is as follows:

[0017] 1. The micrometer screw is divided into a lead screw 4 and an alloy probe 3 (i.e., anvil). The alloy probe 3 includes a coaxial measuring end and a tail shank. The flatness of the measuring end of the alloy probe 3 and the cylindricity of its outer circle are ground. The cylindricity of the outer circle of the lead screw 4 is also ground. The lead screw 4 and the measuring end of the alloy probe 3 have the same diameter. The front end of the lead screw 4 is provided with a coaxial mounting hole that matches the tail shank.

[0018] 2. Wipe the measuring surface of the alloy probe 3 clean with alcohol, and then press the measuring surface onto the measuring surface of the flat gauge block 2 by squeezing (expelling air). During the squeezing process, move the measuring end of the alloy probe 3 downward and position it at the bottom of the "V" groove of the "V" block 1.

[0019] 3. Apply glue to the mounting hole of the lead screw 4, place the lead screw 4 on the bottom of the "V" groove at the rear of the "V" block 1, and push the lead screw 4 forward along the bottom of the "V" groove until the tail of the alloy probe 3 is fitted and bonded to the mounting hole of the lead screw 4.

[0020] 4. After the glue has solidified, remove the firmly bonded lead screw 4 and alloy probe 3. The micrometer screw with the perpendicularity between the measuring end of the alloy probe 3 and the lead screw meeting the 2u requirement is now complete.

[0021] The beneficial effects of this utility model are as follows:

[0022] This utility model uses a micrometer lead screw and anvil bonding auxiliary tool, which is composed of a flat measuring block 2 and a "V" block 1. The alloy measuring head 3 and the lead screw 4 are bonded together on the auxiliary tool to make a micrometer screw, thereby achieving the required accuracy in terms of the flatness of the measuring end face of the lead screw 4 and the perpendicularity to the center of the lead screw 4.
