Abstract
The utility model discloses a simple disc chuck for rapidly positioning a hinge plate. The simple disc chuck comprises a disc chuck body. A center positioning hole is formed in the center of the disc chuck body, wherein the center positioning hole and a step type bearing hole of the hinge plate share the same axis. A first positioning pin and a second positioning pin are arranged on the disc chuck body, the first positioning pin and a hinge positioning hole of the hinge plate share the same axis, and the second positioning pin is used for blocking one side of the hinge plate. Pressing plates which can press the hinge plate and are detachable are arranged on the disc chuck body. Compared with the prior art, the simple disc chuck for rapidly positioning the hinge plate has the following advantages that the hinge plate can be rapidly positioned, and then stepped holes are turned in a lathe, positioning is accurate, the dimensional accuracy of the center distance between the hinge positioning hole and the step type bearing hole is guaranteed, and the using requirement of the hinge plate is met; the simple disc chuck is simple in structure and can be directly installed on a three-jaw chuck of the lathe when being used, and clamping operation is convenient to conduct.
Description
Technical field
The utility model relates to the floral disc of flap location for a kind of subway, in particular a kind of for the simple and easy floral disc of locating hinge plate fast.
Background technology
Wherein a kind of flap that existing subway is used, is useful on the hinge locating hole of locating hinge on it and for bearings mounted step dead eye, the centre-to-centre spacing dimension precision requirement between hinge locating hole and dead eye is higher.To the traditional diamond-making technique of the hinge locating hole on flap and dead eye, be to utilize line cutting to process, and dead eye is step dead eye, line cutting can not be cut stepped hole, therefore traditional method is first with line cutting mode cutting through hole, then in flap bottom surface, add the porose base plate of one deck band and form stepped hole, this kind of method be complex structure not only, processing technology is loaded down with trivial details, and the hole on the base plate increasing often with former flap on the hole concentricity precision of cutting inadequate, can not meet the hinge locating hole of flap and the higher instructions for use of centre-to-centre spacing dimension precision requirement between dead eye.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and what provide a kind of and be convenient to clamping, accurate positioning, can guarantee centre-to-centre spacing dimensional accuracy between hinge locating hole and step dead eye is a kind of for the simple and easy floral disc of locating hinge plate fast.
The utility model is achieved through the following technical solutions:
A kind of simple and easy floral disc for quick locating hinge plate, comprise floral disc body, described floral disc body center is provided with the center positioning hole with the step dead eye concentric of flap, on described floral disc body, be also provided with the first alignment pin of the hinge locating hole concentric of flap and for blocking the second alignment pin of flap one side, on described floral disc body, be also provided with the pressing plate that can push down flap and can dismantle.
Described pressing plate is two.
Described pressing plate one end is fixed on floral disc body by bolt nut.
The utility model has the following advantages compared to existing technology:
A kind of simple and easy floral disc for quick locating hinge plate that the utility model provides, thereby can realize fast location at the lathe stepped hole of getting on the bus out to flap, accurate positioning, has guaranteed the centre-to-centre spacing dimensional accuracy between hinge locating hole and step dead eye, has met the instructions for use of flap.And Ben Jianyi disc chuck structure is simple, during use, be directly installed on the scroll chuck of lathe convenient mounting and clamping.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the have good positioning overall structure schematic diagram of flap of the utility model.
The specific embodiment
Below embodiment of the present utility model is elaborated; the present embodiment is implemented take technical solutions of the utility model under prerequisite; provided detailed embodiment and concrete operating process, but protection domain of the present utility model is not limited to following embodiment.
Referring to Fig. 1 and Fig. 2, a kind of simple and easy floral disc for quick locating hinge plate that the utility model provides, comprise floral disc body 1, floral disc body 1 center is provided with the center positioning hole 11 with step dead eye 21 concentrics of flap 2, on floral disc body 1, be also provided with the first alignment pin 12 of hinge locating hole 22 concentrics of flap 2 and for blocking the second alignment pin 13 of flap 2 one sides, on floral disc body 1, be also provided with two pressing plates that can push down flap 2 and can dismantle (scheming not shown), each pressing plate one end is fixed on floral disc body 1 by bolt nut, bolt screws in the bolt hole 14 on floral disc body 1 and is fixed.
During use, on the first alignment pin 12 that the hinge locating hole of flap 2 22 is inserted on floral disc body 1, one side of flap 2 is leaned against on the second alignment pin 13 of floral disc body 1, now the step dead eye 21 of flap 2 just in time with center positioning hole 11 concentrics of floral disc body 1, then with two pressing plates, flap 2 is pushed down, finally clamping is had to whole floral disc body 1 clamping of flap 2 on the scroll chuck of lathe, start lathe, can carry out the turning of step dead eye 21.In the process in flap 2 turning, floral disc body 1 and the flap 2 being positioned on floral disc body 1 can be along with lathe spindle rotations, flap 2 is owing to being subject to the effect of centrifugal force, have the trend around the first alignment pin 12 rotations on floral disc body 1, therefore its both sides only need the side positioning instant can, the second alignment pin 13 is set on the floral disc body 1 of that side along lathe spindle direction of rotation, for block flap 2 make its rotation process with floral disc body without relatively rotating, all the time guarantee center positioning hole 11 concentrics of step dead eye 21 and floral disc body 1, thereby the hinge locating hole 22 of flap 2 and the centre-to-centre spacing dimensional accuracy between step dead eye 21 have been guaranteed by floral disc body 1.
A kind of simple and easy floral disc for quick locating hinge plate that the utility model provides, thereby can realize fast location at the lathe stepped hole of getting on the bus out to flap 2, accurate positioning, guarantee the centre-to-centre spacing dimensional accuracy between hinge locating hole 22 and step dead eye 21, met the instructions for use of flap 2.And Ben Jianyi disc chuck structure is simple, during use, be directly installed on the scroll chuck of lathe convenient mounting and clamping.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
