Embodiment Construction

[0013] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0014] Such as figure 1 Shown is a turntable 7, which includes a ball housing with an annular groove on its outer edge and a cylindrical body at one end of the ball housing.

[0015] The processing method of above-mentioned turntable, uses a kind of as figure 2 The turntable car fixture shown, the turntable car fixture includes a tapered handle 3 with a central hole, and a cartridge head 5 with a central through hole is installed at the front end of the tapered handle 3 through a pressure ring 6; the cartridge of the present embodiment The outer edge of the head 5 is evenly distributed with five expansion slots that open forward. The cartridge head 5 is provided with a shaping part that matches the inner cavity of the turntable cylinder at the front of the outer edge. The cartridge head 5 is provided with a A tapered hole with a large front and a small rear; a tape...

Abstract

The invention discloses a method for machining a rotary table. A clamp for turning of the rotary table is used. The method comprises the following steps that A, the clamp is installed, i.e., the clamp for turning of the rotary table is arranged on a central taper hole of a lathe through a taper shank, a pulling rod is arranged on a rod body through a threaded center hole, penetrates through the center hole of the lathe and extends out of the tail end of the lathe, and a pressing plate and a nut are sequentially arranged on the threaded section of the rear end of the pulling rod in a penetrating mode, so that the pressing plate and the tail end of the lathe are in abutting connection; B, parts are installed, i.e., a forming portion of an elastic chuck is sleeved with an inner cavity of a cylinder portion of the rotary table, the nut on the threaded section of the tail end of the pulling rod is screwed down, and the rotary table is tightened to the forming portion of the elastic chuck; C, the lathe is started, and a turning tool is used for turning an annular groove in the outer edge of a spherical shell of the rotary table; and D, the nut on the threaded section of the tail end of the pulling rod is loosened, and the rotary table with the machined annular groove only needs to be dismounted. Compared with the prior art, the method for machining the rotary table is advantageous in that the problem that when an annular groove of the outer edge of a spherical shell of a rotary table is machined in the prior art, clamping is difficult can be solved.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a processing method for a turntable on a microscope converter. Background technique [0002] The converter is one of the important parts of the microscope, and the objective lens of the microscope is mounted on the lens barrel through the converter; the turntable is a part on the converter that installs multiple objective lenses; there is a kind of converter turntable, which includes the outer edge A ball housing provided with an annular groove and a cylinder part provided at one end of the ball housing. One of the processes of turntable processing is to process the outer ring groove of the turntable ball shell. At present, the turning method of the ring groove is: first, the three claws on the small three-claw chuck are stretched into the inner cavity of the cylinder body to stretch it, and then the ring groove is turned by using a turning tool. This processing m...
