[0002] CNC camshaft grinder is a high-end CNC machine tool used for grinding cam profiles. It can grind all cams and eccentric outer edges on the entire camshaft. Grinding wheel cutting, worktable movement and master plate indexing can all be performed automatically, so it has high production efficiency and is suitable for use by units that mass-produce automobiles and diesel engines. The grinder is equipped with a self-grinding master plate device, which can use the standard cam to grind the master plate used by this machine tool by the reverse leaning method.

[0003] Based on the above, the inventors found that the existing CNC camshaft grinders have the following deficiencies:

[0004] 1. The bottom of the grinder is in contact with the ground through the leveling feet, which makes it impossible to push and move the grinder to adjust its placement. It is not convenient to add moving measures at the bottom of the grinder to achieve the push and move of the grinder.

[0005] 2. The leveling feet of the grinder rotate and move through threads, which will produce rotational friction with the ground during the adjustment process. It is inconvenient to install conversion measures on the grinder to make the leveling feet only move. Utility Model Content

A universal movable ball 3 in the up and down direction is installed inside the threaded blind hole of the outer shell 2 of the grinder, which is convenient for contact with the ground for movement. A regular hexagonal prism is arranged on the top of the universal movable ball 3, which is convenient for rotation and disassembly by tools. A threaded column is arranged on the top end face of the regular hexagonal prism of the universal movable ball 3, which is convenient for threaded installation. A fixed anti-rotation column 4 in the front-to-back direction is installed inside the threaded hole of the outer shell 2 of the grinder, which is convenient for stopping the rotation of the leveling support column 6, and a threaded column is arranged on the inner end of the fixed anti-rotation column 4, which is convenient for threaded installation.

[0029] Among them, a limiting ring plate is arranged on the outer circumference of the outer end of the threaded column of the fixed anti-rotation column 4, which is convenient for installation and limiting; a regular hexagonal prism is arranged on the outer end face of the threaded column of the fixed anti-rotation column 4, which is convenient for rotation and disassembly through tools; a leveling rotating cylinder 5 in the upper and lower directions is installed inside the bearing circular groove of the outer shell 2 of the grinder through a bearing, which is convenient for the leveling rotating cylinder 5 to rotate; a thread is opened on the inner circumference of the leveling rotating cylinder 5, which is convenient for the leveling support column 6 to be installed through threads; a bearing ring groove is opened on the outer circumference of the bottom of the leveling rotating cylinder 5, which is convenient for installation through bearings; a regular hexagonal structure is arranged on the upper outer circumference of the leveling rotating cylinder 5, which is convenient for rotation through tools and leveling A leveling support column 6 in the up and down directions is installed inside the rotating cylinder 5 through threads, which is convenient for the leveling support column 6 to be raised and lowered through threaded engagement. A thread is opened on the outer circumference of the leveling support column 6 for convenient threaded installation.

A leveling contact plate 7 is installed on the fixing column of the leveling support column 6 through a bearing for convenient contact with the ground. A bearing circular groove is opened in the middle of the top end face of the leveling contact plate 7 for convenient installation of the leveling support column 6 through bearings.

[0030] The specific usage and function of this embodiment are as follows:

[0031] In the utility model, Figure 1 The grinder body 1 is shown in a placed state, at which time the bottom end surface of the leveling contact plate 7 is in contact with the ground, and the lower end of the universal moving ball 3 is off the ground, thereby achieving stable placement of the grinder body 1. When the grinder body 1 is leveled, the spirit level is placed on the grinder body 1, and the leveling rotating cylinder 5 is rotated by a tool to engage with the leveling support column 6 threadedly, so that the leveling support column 6 is lifted and lowered through the threaded engagement, and the leveling contact plate 7 is driven to rise and fall synchronously through the leveling support column 6. At the same time, the state of the spirit level is observed, and the rotation of the leveling rotating cylinder 5 is stopped when the spirit level is in a horizontal state. When the grinder body 1 is pushed and moved, the leveling rotating cylinder 5 is rotated by a tool to engage with the leveling support column 6 threadedly, so that the leveling support column 6 is lifted and lowered through the threaded engagement, and the leveling contact plate 7 is driven to rise synchronously through the leveling support column 6, so that the leveling contact plate 7 rises and leaves the ground, and the universal moving ball 3 is lowered and contacts the ground, and then the grinder body 1 is pushed and moved on the ground through the universal moving ball 3.

[0032] Embodiment 2:

[0033] The difference from Example 1 is that the inner end surface of the limiting ring plate of the fixed anti-rotation column 4 can also be set to a frosted surface, thereby increasing the friction between the inner end surface of the limiting ring plate of the fixed anti-rotation column 4 and the outer shell 2 of the grinder, preventing the fixed anti-rotation column 4 from rotating loose.

[0034] Embodiment three:

[0035] The difference from the first embodiment is that the regular hexagonal prism of the fixed anti-swivel column 4 can also be set as a regular heptagonal prism, so that the fixed anti-swivel column 4 can only be rotated by a special tool that cooperates with the regular heptagonal prism, preventing non-staff from rotating and disassembling the fixed anti-swivel column 4.
