Description

Technical Field

[0001] The utility model relates to the technical field of clamping tooling, in particular to a clamping tooling for an outside diameter micrometer. Background Art

[0002] An outside micrometer is a precision measuring tool used to measure the outside diameter of a workpiece. It provides highly accurate measurements and is commonly used in quality control and precision engineering. The accuracy of an outside micrometer is directly related to product quality and performance, making it crucial during manufacturing and inspection. Clamping fixtures are used to secure the workpiece, ensuring its position and orientation remain stable during measurement, preventing hand shake or movement from affecting the accuracy of the measurement.

[0003] A common micrometer clamping fixture includes a base, a support and a slot. When in use, the micrometer is directly clamped inside the slot. However, due to the different thicknesses of the clamping arms of the micrometer, this method cannot adapt well when clamping. In addition, the stability of the micrometer clamping is reduced by only clamping, which cannot meet the working requirements of the clamping fixture. Therefore, a clamping fixture for outside diameter micrometers is proposed. Utility Model Content

[0004] (1) Technical problems solved

[0005] In view of the deficiencies of the prior art, the utility model provides a clamping fixture for an outside micrometer to solve the technical problem that good adaptation cannot be achieved during clamping due to different thicknesses of the clamping arms of the micrometer.

[0006] (2) Technical solution

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a clamping tool for an outside micrometer, comprising:

[0008] A base, wherein a support is connected to the middle position of the top of the base, and a limit bolt is screwed to the upper side of the front of the support;

[0009] The clamping slot is arranged in the middle of the top end of the pillar, and the rear end of the limiting bolt passes through the corresponding position of the inner cavity of the clamping slot.

[0010] Preferably, a screw is installed on the top rear side of the base through a ball bearing, an L-shaped seat is screwed on the top of the screw, and a turntable is sleeved on the outer lower side of the screw to facilitate driving the screw to rotate.

[0011] Preferably, the right end of the L-shaped seat is connected to a slider, and a slide groove is opened on the upper rear side of the pillar. The slider and the slide groove are both convex-shaped. The slider is inserted into the inside of the slide groove, which facilitates the limiting of the L-shaped seat so that the L-shaped seat can move up and down when the screw rotates.

[0012] Preferably, a pressure rod is inserted into the inner upper side of the L-shaped seat, and a through groove is provided on the inner left side of the pressure rod and the inner lower side of the L-shaped seat. A limiting rod is inserted into the through groove inside the pressure rod, and the front and rear ends of the limiting rod are connected to the corresponding positions inside the L-shaped seat.

[0013] Preferably, a connecting rod is installed in the middle position of the bottom of the pressure rod, and a limit plate is installed on the outside of the connecting rod at a position above the through slot. After the micrometer is inserted into the slot, the pressure rod is pushed to press on the top of the clamping arm of the micrometer, and then the L-shaped seat is driven up and down by rotating the screw, so that the pressure rod presses the micrometer, thereby improving the stability of the micrometer clamping.

[0014] Preferably, a nut is screwed onto the outside of the connecting rod at a position below the through slot, and anti-slip grooves are circumferentially arranged on the outside of the nut to facilitate the rotation of the nut.

[0015] (3) Beneficial effects
