Abstract
Description
Technical Field
[0001] The utility model relates to an inspection tool for measuring the verticality between a main shaft axis and an X-axis or Y-axis motion direction. Background Art
[0002] Due to the ever-increasing demands on machined parts in industries such as precision instruments and aerospace, existing technology typically involves mounting a lever micrometer on the spindle, with its probe contacting a square gauge. The spindle is rotated, causing the lever micrometer to rotate along the axis, and the reading is taken. The maximum value is used as the measurement result. However, traditional methods for checking the perpendicularity of the spindle axis to the X or Y axis of motion suffer from the problem of the micrometer holder not being perfectly clamped, resulting in inaccurate measurements.
[0003] Currently, in the market, the micrometer is basically adsorbed on the spindle. The micrometer base is adsorbed on the spindle to restrict only three degrees of freedom. Based on the above description, there is a great need for a fixture that can restrict all degrees of freedom except spindle rotation. Utility Model Content
[0004] The main technical problem solved by the utility model is to provide an inspection tool for measuring the perpendicularity between the spindle axis and the X or Y axis movement direction. The utility model has a simple structure and is easy to use. At the same time, the inspection of the perpendicularity between the spindle axis and the X or Y axis movement direction can be intuitively reflected on the dial indicator, which is convenient for debugging personnel to adjust the mechanical performance and assembly method. The utility model solves the traditional technology of under-positioning of the dial indicator adsorbed on the spindle, and can better improve the assembly accuracy of the machine tool.
[0005] In order to solve the above technical problems, a technical solution adopted by the present invention is: providing an inspection tool for measuring the perpendicularity between the spindle axis and the X or Y axis movement direction, which is used to fix the dial indicator on the spindle, including a tool base, and the tool base is arranged in an L-shaped structure, including two mutually perpendicular first right-angled surfaces and a second right-angled surface, the surface of the first right-angled surface is penetrated by a first locking hole and is fixed to the end face of the spindle by a first bolt, the surface of the second right-angled surface is penetrated by a second locking hole and is locked and fixed to the side of the base of the dial indicator by a second bolt, and the second right-angled surface is arranged parallel to the central axis direction of the dial indicator in the length direction.
[0006] In a preferred embodiment of the present invention, the first locking hole is arranged in a strip-shaped hole in the length direction of the first right-angled surface.
[0007] In a preferred embodiment of the present invention, at least two first bolts are provided and fixed to the end surface of the main shaft in the length direction of the first locking hole.
[0008] In a preferred embodiment of the present invention, the second locking hole is arranged in a strip-shaped hole in the length direction of the second right-angled surface.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0015] See also Figure 1-Figure 2 , the embodiments of the present utility model include:
[0016] An inspection fixture for measuring the perpendicularity between the spindle axis and the X or Y axis movement direction is used to fix the micrometer 1 on the spindle 2 and includes a fixture base 3.
[0017] The tooling base 3 is arranged in an L-shaped structure, including a first right-angled surface 31 and a second right-angled surface 32 perpendicular to each other, for providing vertical installation and fixation.
[0018] A first locking hole 311 is provided on the surface of the first right-angled surface 31 and is fixed to the end surface of the main shaft 2 by a first bolt 4. The first locking hole 311 is provided in a strip-shaped hole in the length direction of the first right-angled surface 31 to provide adjustment and fixation in the length direction of the first right-angled surface 31.
[0019] At least two first bolts 4 are provided and fixed to the end surface of the main shaft 2 in the length direction of the first locking hole 311 to ensure stable fixation of the first right-angled surface 31 .
[0020] A second locking hole 321 is provided on the surface of the second right-angled surface 32 and is locked and fixed to the side of the base 11 of the micrometer 1 by a second bolt 5. Specifically, the second locking hole 321 is provided in a strip-shaped hole in the length direction of the second right-angled surface 32 to provide adjustment and fixation of the micrometer 1 in the length direction of the second right-angled surface 32.
[0021] At least two second bolts 5 are provided and are locked and fixed to the side surface of the base 11 of the dial gauge 1 in the length direction of the second locking hole 321 to ensure stable fixation of the dial gauge 1.
[0022] The second right-angled surface 32 is arranged parallel to the central axis direction of the dial gauge 1 in the length direction, ensuring the perpendicularity between the dial gauge 1 and the main shaft 2.
[0023] The above structure limits the translational and rotational freedom of dial indicator 1 in the X, Y, and Z axes, ensuring that dial indicator 1 is not affected by these degrees of freedom, enabling more accurate precision measurements. Next, place square marble 6 on the work surface, adjust the Y axis of dial indicator 1 so that it contacts marble 6 and registers a reading. Using the Z surface of marble 6 as a reference, rotate spindle 2 so that the spindle axis is perpendicular to the X or Y axis of motion to check for accuracy.

At the same time, the inspection of the perpendicularity between the spindle axis and the X or Y axis movement direction can be intuitively reflected on the micrometer, which is convenient for debugging personnel to adjust the mechanical performance and assembly method, solves the traditional technology of under-positioning of the micrometer adsorbed on the spindle, and can better improve the assembly accuracy of the machine tool.
