Embodiment Construction

[0025] The present invention will be described in more detail below in conjunction with the accompanying drawings. It should be noted that the following description of the present invention with reference to the accompanying drawings is only illustrative rather than limiting. Different embodiments can be combined with each other to form other embodiments not shown in the following description.

[0026] The invention provides a center hole fixture of a vertical lathe, referring to figure 1 and figure 2 , the vertical lathe center hole fixture includes a self-centering clamping mechanism 10 and a plurality of pressing mechanisms 20 . Wherein, the self-centering clamping mechanism 10 is arranged on the base 30, the self-centering clamping mechanism 10 includes an adjusting part 11 and a clamping part 12, and the adjusting part 11 adjusts the diameter of the clamping part 12 along the self-centering clamping mechanism 10. To (the radial direction in this article refers to the r...

Abstract

The invention relates to the field of processing technology, in particular to a vertical lathe central hole clamp which comprises a self-centering clamping mechanism and a plurality of compressing mechanisms, wherein the self-centering clamping mechanism is arranged on a base and comprises an adjusting part and a clamping part; the adjusting part adjusts the clamping part to stretch into or stretch out in the radial direction of the self-centering clamping mechanism; the compressing mechanisms are arranged on the base at intervals around the self-centering clamping mechanism, and the positionsof the compressing mechanisms can be radially adjusted. When a to-be-machined component is in the clamping state, the clamping part is propped against the side face of the internal part of the to-be-machined component, and the compressing mechanisms are propped against the top of the to-be-machined component. The invention aims to provide the vertical lathe central hole clamp which has the self-centering and product universality and reduces plenty of economic cost and man hour and manpower consumed when the clamp is changed.

Description

technical field [0001] The invention relates to the field of processing technology, in particular to a center hole fixture of a vertical lathe. Background technique [0002] The full name of the manual four-jaw self-centering chuck in the prior art is a manual four-jaw self-centering chuck for machine tools, which is composed of a disc body, four small bevel teeth, and a pair of jaws. The four small bevel teeth mesh with the coil wire, and the back of the coil wire has a flat thread structure, and the claws are installed on the flat thread in equal parts. When the small bevel tooth is pulled with a wrench, the coil wire will rotate, and the flat thread on its back side will make the claws approach or withdraw from the center at the same time. Because the pitches of the flat rectangular threads on the coil wire are equal, the movement distance of the four claws is equal, which has the function of self-centering. [0003] The currently used four-jaw chuck is easy to enter im...
