Abstract
The invention discloses a turning clamp for an adjusting screw and relates to the technical field of tool clamp manufacturing. The turning clamp comprises a cone with a cylindrical portion. An elastic clamp head is arranged on the cylindrical portion of the cone. The elastic clamp head is installed at the front end of the cylindrical portion through a split junk ring nut. A plurality of expanding grooves with forward openings are evenly distributed in the outer edge of the elastic clamp head. A cone portion with the front being small and the rear being large is arranged on the front portion of the outer edge of the elastic clamp head. A threaded hole is formed in the front end of the elastic clamp head. A limiting table is arranged behind the threaded hole. The elastic clamp head is sleeved with a tightening nut. A conical hole matched with the cone portion of the elastic clamp head is formed in the front end of the tightening nut, wherein the front of the conical hole is small and the rear of the conical hole is large. The tightening nut is arranged on the cylindrical portion through threads. Compared with the prior art, the turning clamp is advantageous in that the problems that when an upper threaded section of an adjusting screw is turned, the positional accuracy of a conical hole is likely to be out of tolerance and the threaded section is prone to damage are solved.
Description
Technical field
The present invention relates to frock clamp manufacturing technology field, especially a kind of vehicle clamper for microscope adjustment screw.
Background technology
Microscope is widely used in research institute's work such as biology, cytology, histology, pharmaceutical chemistry; Microscope there is a lot of adjustment screw; Have a kind of adjustment screw, this adjustment screw has the upper thread segment that lower thread segment and the external diameter be located on this lower thread segment are M, and thread segment top is provided with a up big and down small taper hole on described; By the circularity of designing requirement taper hole and the required precision of taper hole to the axiality of upper thread segment external diameter M high.One of manufacturing procedure of adjustment screw is thread segment and taper hole on car, and in current adjustment screw, the method for turning of thread segment is: the upper three-jaw of folder is processed by after thread segment cylindrical parcel under the adjustment screw completing turning with copper sheet.There is the circularity of taper hole and the precision of taper hole to the axiality of upper thread segment external diameter M is overproof and thread segment is damaged problem in this processing method.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of adjustment screw vehicle clamper, existing to the positional precision of the taper hole easily problem that is easily damaged of overproof and thread segment during thread segment turning in adjustment screw to solve.
The technical scheme that technical solution problem of the present invention adopts is: this adjustment screw vehicle clamper includes the cone of cylindrical portion, and the cylindrical portion of described cone is provided with cartridge clip head, and described cartridge clip head is contained in described cylindrical portion front end by opening limit pressure ring nut; Described cartridge clip head in being all distributed with many openings spreading groove forward in outer rim, is provided with pre-small post-large cone portion in outer rim front portion, is provided with screwed hole, is provided with limiting stand in described screwed hole rear in front end; Outside described cartridge clip head, be arranged with tightening nut, described tightening nut is provided with the pre-small post-large taper hole matched with the cone portion of described cartridge clip head in front end, described tightening nut is contained in described cylindrical portion by screw thread.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect: owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect: during due to parts fixation, the thread segment of adjustment screw is screwed in the screwed hole of centre of cartridge clip head, the termination of thread segment and the limiting stand of cone portion are abutted against, tighten tightening nut again, make the cone portion of tightening nut by the cone portion of taper hole extruding cartridge clip head, the lower thread segment of adjustment screw is fixed, the processing of thread turning processing and taper hole can be carried out to the upper thread segment of adjustment screw, clamped one time can complete the external screw thread processing of thread segment and the processing of taper hole, the circularity of taper hole and the precision of taper hole to the axiality of upper thread segment external diameter M high, also can not damage the lower thread segment of adjustment screw during clamping simultaneously.
Accompanying drawing explanation
Fig. 1 is the structural representation of the adjustment screw of the embodiment of the present invention.
Fig. 2 is the structural representation of the embodiment of the present invention.
Fig. 3 is the structural representation of the cartridge clip head of the embodiment of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described:
Adjustment screw 5 as shown in Figure 1 has the upper thread segment that lower thread segment and the external diameter be located on this lower thread segment are M, has a up big and down small taper hole of 90 degree at upper thread segment top; By the circularity of this taper hole of designing requirement and the required precision of taper hole to the axiality of upper thread segment external diameter M high.
Adjustment screw vehicle clamper as shown in Figure 2 comprises the cone 1 being provided with cylindrical portion 1-1, is provided with thread segment at the rear portion of cylindrical portion 1-1, has screwed hole in the front portion of cylindrical portion 1-1; The cylindrical portion 1-1 of cone 1 is equipped with cartridge clip head 4, and cartridge clip head 4 is contained in the front end of cylindrical portion 1-1 by opening limit pressure ring nut 3, opens limit pressure ring nut 3 and is made up of the upper semi-ring nut of two semicircles and lower semi-ring nut; Cartridge clip head 4 rear portion of the present embodiment is provided with locating dowel, cartridge clip head 4 is provided with pre-small post-large cone portion 4-3 in outer rim front portion, joint pin is provided with between locating dowel and cone portion 4-3, during installation, semi-ring nut and lower semi-ring nut sleeve being opened limit pressure ring nut 3 with the two being connected into one by soldering on joint pin, will limit pressure ring nut 3 being opened by being threaded in the screwed hole of cylindrical portion 1-1 front portion; Cartridge clip head 4 is in outer rim in being all distributed with three openings spreading groove 4-1 forward, and cartridge clip head 4 is provided with screwed hole of centre 4-2 in front end; The cone portion 4-3 of cartridge clip head 4 is provided with limiting stand 4-4 in screwed hole of centre 4-2 rear, as shown in Figure 3; Outside cartridge clip head 4, be set with a tightening nut 2, tightening nut 2 is provided with the pre-small post-large taper hole matched with the cone portion of cartridge clip head 4 in front end, and tightening nut 2 is sleeved on cylindrical portion 1-1 by being threaded with the thread segment at cylindrical portion 1-1 rear portion.
During work, adjustment screw vehicle clamper is contained in the center taper hole of lathe by cone 1; Unscrew tightening nut 2, first the lower thread segment of adjustment screw 5 is screwed in the screwed hole of centre 4-2 of cartridge clip head 4, the limiting stand 4-4 of the termination of the lower thread segment of adjustment screw 5 and cartridge clip head 4 cone portion 4-3 is abutted against; Tighten tightening nut 2 again, make tightening nut 2 by the cone portion of taper hole extruding cartridge clip head 4, the lower thread segment of adjustment screw 5 is tightened up; Start lathe, adopt the upper thread segment of lathe tool to adjustment screw 5 to carry out thread turning processing; First adopt the top of centre drill to the upper thread segment of adjustment screw 5 to carry out the preboring of 90 degree of taper holes, then adopt lathe tool to carry out finish turning to taper hole; Unscrew the adjustment screw 5 that tightening nut 2 has unloaded processing.
