Embodiment Construction
[0011] The present invention will be described in further detail below in conjunction with accompanying drawing embodiment:
[0012] figure 1 The turntable inner hole car fixture shown mainly includes a clamp body 1, an elastic collet 2, a positioning sleeve 3, a locking bolt 4 and a pressure sleeve 5, and the clamp body 1 includes an integrally formed Morse taper shank 1-1 arranged in sequence , connecting plate 1-2 and positioning shaft 1-3, the big end of Morse taper shank 1-1 is connected with connecting plate 1-2, positioning shaft 1-3 is set coaxially with mode taper handle 1-1, connecting plate The outer diameter of 1-2 is larger than the outer diameter of the large end of Morse taper shank 1-1 and the positioning shaft 1-3. The positioning shaft 1-3 is a stepped shaft, and the diameter of the outer shaft section of the stepped shaft is smaller than that of the connecting plate 1-3. 2 Connected shaft section diameter. The collet 2 is set on the positioning shaft 1-3. ...

The invention discloses a rotating disk inner hole turning clamp and relates to the technical field of machining tools. The rotating disk inner hole turning clamp comprises a clamp body, and the clampbody comprises a connection plate and a positioning shaft; the positioning shaft is sleeved with an elastic chuck; the elastic chuck is composed of a connection base and an elastic opening part; theexterior of the elastic chuck is sleeved with a positioning sleeve which is provided with a fixed base connected with the connection base; the connection base and the fixed base are connected and fixed to the connection plate through bolts; a pressing sleeve is inserted to the tail end of the positioning sleeve, and comprises a pressing plate and a sleeve body inserted into the position between the positioning sleeve and the elastic chuck; the inner diameter of the sleeve body is gradually decreased in the direction from the inserted end to the pressing plate; and the positioning sleeve is provided with a locking bolt used for locking the pressing sleeve. The rotating disk inner hole turning clamp solves the problem that a rotating disk inner hole turning clamp of an existing objective microscope is low in reliability.
Description
technical field [0001] The invention relates to the technical field of machining tooling, in particular to a turntable inner hole turning fixture. Background technique [0002] The objective lens converter is an important component of the mechanical device serving the microscope optical system. It is installed at the lower end of the lens barrel, including the fixed plate, the turntable and the positioning mechanism, etc. The fixed plate is fixed on the positioning mechanism, and the turntable rotates freely around the fixed plate. There are two to six holes on the top for installing the objective lens. Rotating the turntable can make the objective lenses of different multiples rotate to the optical axis of the microscope in turn to ensure that the light rays of the objective lens and the eyepiece are aligned. In order to make the turntable rotate more smoothly, balls and washers are arranged between the fixed plate and the inner wall of the turntable. In order to limit the ...
