[0013] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but they are not intended to limit the present invention.

[0014] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0015] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0016] See also Figure 1 and Figure 2As shown, a structural diagram of an axial constant pressure device suitable for a shaft tooth clearance measuring device is shown, wherein the device comprises a first guide column 1, a second guide column 2, a gasket 3, a spring 4, a mounting plate 5, a slider 6, a bottom plate 7, a slide rail 8, a pressure block 9, an upper claw piece 10, and a lower claw piece 11. The first guide column 1 and the second guide column 2 are arranged in parallel on the mounting plate 5, the slider 6 is connected to the mounting plate 5, the bottom plate 7 is provided with a slide rail 8 matching the slider 6, the upper claw piece 10 and the lower claw piece 11 are connected to the cylinder, and the upper claw piece 10 and the lower claw piece 11 are connected to the cylinder. The plate 10 and the lower claw plate 11 are sleeved on the first guide column 1 and the second guide column 2, the cylinder can drive the upper claw plate 10 and the lower claw plate 11 to move on the first guide column 1 and the second guide column 2, the spring 4 is sleeved on the second guide column 2, and the spring 4 is sleeved on the lower part of the connection between the lower claw plate 11 and the second guide column 2, the transmission mechanism is connected to the slider 6, and drives the slider 6 to move on the slide rail 8, the pressure block 9 is arranged at the top of the second guide column 2, and the gasket 3 is arranged at the connection between the spring 4 and the second guide column 2.

[0017] In this embodiment, the cylinder is a rodless cylinder, and the way in which the cylinder connects and controls the upper claw piece and the lower claw piece is a common way in the prior art, specifically including: after the workpiece is placed on the machine tool, the detection switch sends a workpiece arrival signal to the programmable controller, and the programmable controller controls the solenoid valve to switch and pass compressed gas into the rodless chamber of the cylinder. The upper claw piece and the lower claw piece are driven to clamp through the internal mechanical structure of the cylinder.

[0018] In this embodiment, the vertical distance between the upper claw and the shaft tooth is greater than the vertical distance between the lower claw and the shaft tooth.
