Embodiment 1

[0025] Example 1, such as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 , Figure 14 and Figure 15The illustrated embodiment 1 includes a base 2 whose bottom surface 17 matches the track of the length measuring machine, a spacer 3 , a bracket 4 , a clamping assembly, a measuring head fixing frame assembly and a measuring head fixing seat 40 . Have screw hole I on the side wall of base 2, it is clamped and fixed on the track side wall of length-measuring machine by locking bolt A1. There are concentric screw holes on the base 2, spacer 3, bracket 4 and probe fixing seat 40 respectively, and the base 2, spacer 3 and bracket 4 are fixed by long screws 16 or the base 2, spacer 3 and the probe are fixed Seat 40 is fastened and fixed by long screw 42, and 15 is the concentric screw hole that has on pad 3, and 20 is the concentric screw hole that has on support...

Embodiment 2

[0026] Embodiment 2, other structures of this embodiment are completely the same as Embodiment 1, except that there is no probe fixing frame assembly in this embodiment.

[0027] 1. The following is an example of measuring the inner diameter dial indicator (the division value is 1 μm, and the indication error is required to be no more than 7 μm) to introduce the working principle of the device in detail.

[0028] 1. Installation: first install a flat measuring cap on the measuring rod of the optical meter tube of the length measuring machine, align the tail pipe of the length measuring machine with any integer value, and then install the base, pad, bracket and clamping assembly of the present invention On the guide rail of the length measuring machine. Compress the inner diameter gauge by 1 / 4 turn and install it in the clamping hole, loosen the locking bolt A, roughly adjust the workbench left and right, make the movable measuring head of the inner diameter gauge roughly in th...

Abstract

The invention discloses a measuring instrument testing fixture for a length measuring machine. The measuring instrument testing fixture for the length measuring machine comprises a base, a cushion block, a support, a clamping assembly and a measuring head fixing base, wherein the bottom of the base is matched with a rail of the length measuring machine; concentric screw holes are formed in the base, the cushion block, the support and the measuring head fixing base respectively; the base, the cushion block and the support, or the base, the cushion block and the measuring head fixing base are tightly fixed by long screws; a sliding rail is arranged on the side surface of the support; the clamping assembly comprises a clamping base, and a clamping plate which is detachably fixed with the clamping base; one end of the clamping base is arranged on the sliding rail of the support in a fixable and slidable way; clamping slots forming a complete clamping hole are formed in opposite surfaces of the clamping base and the clamping plate; an instrument rod hole is formed in the upper end part of the measuring head fixing base; a screw hole V which is communicated with the instrument rod hole is formed in the upper end surface of the measuring head fixing base; and a locking bolt E is installed in the screw hole V. When the length measuring machine uses the measuring instrument testing fixture, a workpiece size measuring instrument is tested or calibrated on the premise of not changing the original performance of the length measuring machine, and multiple functions of the length measuring machine are realized.

Description

technical field [0001] The invention belongs to the field of geometric quantity measurement, and relates to a fixture for enabling a length measuring machine to verify or calibrate a measuring instrument. Background technique [0002] Some mechanical processing units, in order to realize the size measurement of various workpieces, need to purchase length measuring machines, inner diameter dial indicators, inner diameter dial indicators, lever dial indicators, lever dial indicators, 0.01mm indicator meters, 0.02mm indicator meters, etc. A large number of measuring instruments and equipment of various specifications such as meters, 0.002mm dial indicators, torsion spring meters, digital display meters, dial-type displacement sensors, etc. The length measuring machine is a precision optical instrument for measuring large-sized workpieces. Its working principle is to use three scales with different division values ​​and ranges, and to apply an optical meter tube and an optical m...
