Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
In the description of the present invention, it is to be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on those shown in the drawings, and are merely for convenience of description and simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention. In addition, in the description of the present invention, "a plurality" means two or more unless specifically limited otherwise.
Referring to fig. 1-4, the present invention provides a technical solution: a ball valve rod milling tool comprises a tool platform 1, wherein a pull rod 9 is vertically arranged on the tool platform 1; the tool seat body 5 and the equal-height blocks 14 which are equal in height to the tool seat body 5 are respectively arranged on two sides of the pull rod 9, the pressing plate 6 is arranged on the upper sides of the tool seat body 5 and the equal-height blocks 14, and the tool seat body 5 and the equal-height blocks 14 are fixed on the tool platform 1 through the pressing plate 6 and the pull rod 9; rotatable locating sleeve 4 is installed on the tool base body 5, and the locating sleeve 4 is used for installing a ball valve rod workpiece to be processed.
In this embodiment, the positioning sleeve 4 is provided with a locking screw 11 and a locking block 12, and the positioning sleeve 4 fixes the workpiece in the positioning sleeve 4 through the locking screw 11 and the locking block 12. The upper side of the pressure plate 6 is provided with a spring washer 7 and a compression nut 8, and the spring washer 7 and the compression nut 8 are sleeved on a pull rod 9.
Specifically, the tool platform 1 is also vertically provided with a supporting and adjusting screw 2, the supporting and adjusting screw 2 is arranged on the side edge of the pull rod 9, a supporting block 3 is installed at the top of the supporting and adjusting screw 2, and the supporting block 3 is used for supporting the rear end of a workpiece.
Wherein, the circumference of position sleeve 4 is gone up the symmetry and is provided with location taper pin 13 and rotating pin 10, sets up the ring channel of adaptation on the frock pedestal 5, and location taper pin 13 and rotating pin 10 set up in the ring channel.
