Embodiment Construction

[0014] The present invention will be described in further detail below in conjunction with accompanying drawing:

[0015] figure 1 For the pressure ring 7-1, it is necessary to pass the figure 2 The outer circle of the shown pressure ring sleeve blank 7 is turned and cut to obtain the pressure ring 7-1.

[0016] Such as figure 2 The shown clamping fixture includes a taper shank 1 provided with an expansion sleeve portion 1-3, and the expansion sleeve portion 1-3 of this embodiment is evenly distributed on the outer edge with four expansion slots 1-3 that open forward. 2. The front end of the expansion sleeve 1-3 is provided with a taper hole 1-1 of the expansion opening connected to the inner cavity of the expansion sleeve, such as image 3 with Figure 4 As shown; outside the expansion sleeve part 1-3 of the taper handle 1, a positioning sleeve 2 is threaded, and a pressure ring installation part 2-1 is provided at the front of the positioning sleeve 2; The center hole...

Abstract

The invention discloses a clamping ring lathe clamp, and relates to the technical field of tool clamp manufacturing. The clamping ring lathe clamp comprises a taper shank with an expansion sleeve part. A plurality of expansion grooves with forward openings are evenly distributed in the outer edge of the expansion sleeve part. An expansion part taper hole communicated with an inner cavity of the expansion sleeve part is formed in the front end of the expansion sleeve part, wherein the front portion of the expansion part taper hole is larger than the rear portion of the expansion part taper hole. The expansion sleeve part is sleeved with a positioning sleeve in a threaded manner. A pressing ring installation part is arranged on the front portion of the positioning sleeve. A central hole communicated with the inner cavity of the expansion sleeve part is formed in the taper shank. A pull rod is arranged in the central hole in a penetrating manner. A taper sleeve with the outer edge matched with the expansion taper hole is arranged on the front portion of the pull rod through threads. Compared with the prior art, the clamping ring lathe clamp can solve the problem that ellipses are prone to appearing when the outer circle of an existing clamping ring is lathed.

Description

technical field [0001] The invention relates to the technical field of tooling and fixture manufacturing, in particular to a turning fixture for a pressure ring 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 installed on the lens barrel through the converter; the pressure ring is a part of the converter, and there is a pressure ring of the converter, which is a cylindrical thin wall pieces. One of the processes of pressing ring processing is turning and cutting the outer circle of the pressing ring; the current method of turning the outer circle of the pressing ring is: the pressing ring after the inner hole is placed on the expanding sleeve with a tapered handle, and then a expanding sleeve with a tapered body is used. After the screw on the top expands the expansion sleeve and tightens the pressure ring, the outer circle of the pressure ring can be turned. ...
