The main body is connected into a whole body with a large lathe carriage through the bolts; a sleeve is arranged on the main body; the screw rod is arranged in an inner hole of the main body; the end face bearings, the indexing disc, the keys, the shim block, the nuts and the screw are respectively arranged on the screw rod; the two end face bearings are respectively installed at the front shaft shoulder and the back shaft shoulder of the screw rod and match with the end faces of the main body; the keys are installed between the inner hole and an outer path of the screw rod; the indexing disc, the shim block and the end face bearings are fixed on the main body through the screw thread fit of the nuts and the screw rod; and the screw on the screw rod is connected with the slipway to drive the slipway to move linearly to finish a straight line. The machine indexing device is characterized in that the machine indexing device further comprises a handle, a spring, a guide sleeve, a locating pin and a sleeve; the guide sleeve is arranged on the indexing disc; the locating pin and the spring are respectively installed inside the guide sleeve; and the handle is installed on the locating pin. The machine indexing device is simple in structure, convenient to operate, low in cost and high in indexing precision.
Description
Technical field
The utility model belongs to the technical field of a kind of engine lathe middle carriage straight line calibration and anchor clamps calibration, particularly a kind of mechanical dividing device.
Background technology
Along with the application of a large amount of Digit Control Machine Tools, make a large amount of engine lathes by idle.Many factories purchase the Digit Control Machine Tool another side on the one hand to the engine lathe technological transformation, make it satisfy the needs of special-purpose processing, and existing anchor clamps calibration and equipment straight line calibration generally adopt servomotor or stepper motor, make complicated cost height, need configuration control system separately.Shown in Figure 1, conventional equipment does not have the calibration function to have only feed function.
Summary of the invention
The utility model purpose provides a kind of novel mechanical indexing means.
The technical solution of the utility model is achieved in that
The mechanical dividing device, it is by body, index dial, key, nut, pad, the end face bearing, leading screw, screw and slide unit are formed, body combines as a whole by bolt and lathe saddle, cover is housed on the body, leading screw is contained in the endoporus of body, the end face bearing, index dial, key, pad, nut, screw is contained on the leading screw respectively, two end face bearings are contained in shaft shoulder place, leading screw front and back respectively, and cooperate with the end face of body, between the endoporus of index dial and the leading screw external diameter key is housed, the threaded engagement of nut and leading screw is with index dial, pad, the end face bearing fixing is on body, screw on the leading screw connects drive slide unit rectilinear motion and finishes straight line with slide unit, it is characterized by: it is also by handle, spring, guide pin bushing, the location pin and sleeve is formed, guide pin bushing is housed on the index dial, alignment pin is housed respectively in the guide pin bushing, spring is equipped with handle on the alignment pin.
It is low to the utlity model has easy to operate cost simple in structure, characteristics such as indexing accuracy height.
Description of drawings
Fig. 1 is original lathe dial leading screw schematic diagram;
Fig. 2 is a structural representation of the present utility model.
Specific embodiments
Describe specific embodiments of the present utility model in detail below in conjunction with accompanying drawing.
The mechanical dividing device, it is by body 4, index dial 3, key 7, nut 8, pad 9, the end face bearing, leading screw 12, screw 13 and slide unit 14 are formed, body 4 combines as a whole by bolt and lathe saddle, on the body 4 cover is housed, leading screw 12 is contained in the endoporus of body 4, the end face bearing, index dial 3, key 7, pad 9, nut 8, screw 13 is contained in respectively on the leading screw 12, two end face bearings 10 and 11 are contained in shaft shoulder place, leading screw 12 front and back respectively, and cooperate with the end face of body 4, between the endoporus of index dial 3 and leading screw 12 external diameters key 7 is housed, the threaded engagement of nut and leading screw 12 is with index dial 3, pad 9, the end face bearing fixing is on body 4, screw 13 on the leading screw 12 connects drive slide unit 14 rectilinear motions and finishes straight line with slide unit 14, it is characterized by: it is also by handle 1, spring 2, guide pin bushing 15, alignment pin 5 and cover 6 are formed, guide pin bushing 15 is housed on the index dial 3, alignment pin 5 is housed respectively in the guide pin bushing 15, spring 2 is equipped with handle 1 on the alignment pin 5.
Embodiment: as shown in Figure 2, alignment pin is extracted in body apertures, index dial and body can rotate mutually, can realize the calibration of different angles by the hole on the body.Index dial drives leading screw and rotates, and drives the slide unit straight line by screw and moves.Leading screw 12 is realized axial restraint by two end face bearings 10, bearing 11 and pads 9, index dial 3, nut 8.Leading screw 12 is realized slowly running by the gap with body 4.Body 4 processes locating hole as required, and index dial 3 cooperates with body 4 holes by coupled spring guide 2, alignment pin 5 realizes that calibration, alignment pin 5 whenever pull out realization calibration in the hole of inserting body 4 after angle of index dial 3 rotations once more.Index dial 3 turns over the pitch of angle by leading screw 12 and the distance that needs at every turn, and to remove long-pending, integer part be that the whole number of turns, the remainder part that index dial 3 need turn over is exactly the angle that index dial turns over by 360 degree five equilibriums.Move drive slide unit 14 by female 13 straight lines of the rotating band movable wire of index dial and move realization straight line calibration.
