Abstract

The utility model discloses a positioning device. The positioning device comprises a base seat, a drive piece controlled by a controller and installed inside the base seat, a gear synchronously connected with an output end of the drive piece, four positioning plates, four guide rods and a bearing table which is installed on the base seat and used for bearing a workpiece to be machined, wherein each guide rod is provided with insections matched with the gear, two of the four guide rods extend along the X-axis direction, the other two guide rods extend along the Y-axis direction, the four guide rods are all meshed with the gear, and the four positioning plates are respectively fixed end portions of the four guide rods far away from the gear and are evenly distributed on the periphery of the base seat. The positioning device can automatically and accurately position the workpiece to be machined.

Description

Positioner

Technical field

The utility model relates to a kind of positioner.

Background technology

Need before machine tooling workpiece to be processed such as the face glass workpiece to be processed is positioned; The main at present range estimation through the operator positions processing work, so, and in the time of not only need spending the plenty of time; And damage workpiece to be processed owing to the location is inaccurate, even injure the operator easily.

The utility model content

To the deficiency of prior art, the purpose of the utility model is intended to provide a kind of can carry out accurate positioning means for positioning to workpiece to be processed automatically.

For realizing above-mentioned purpose, the utility model adopts following technical scheme:

A kind of positioner is characterized in that: this positioner comprises:

One base;

One actuator by controller control is installed in the base;

One gear is connected in the output of actuator synchronously;

Four guide rods, each guide rod is provided with the groove that is complementary with this gear, and wherein two guide rods extend along X-direction, and two guide rods extend along Y direction in addition, and four guide rods all are engaged on the gear;

Four location-plates are separately fixed at the end of four guide rods away from this gear, and four location-plates are evenly arranged in the periphery of base; And

One is installed in the plummer on this base, is used to carry a workpiece to be processed.

This base is installed on the workbench of lathe, and can move along with workbench.

Each guide rod is installed in the bearing of base slidably.

Wherein two adjacent location-plates extend holding division toward the direction of actuator, and the end face of other two location-plates is provided with the blocking part.

This runner assembly is stepper motor or rotary cylinder.

This plummer is a vacuum adsorption plate.

Above-mentioned positioner drives guide rod through this runner assembly, so that this first and second location-plate withstands workpiece to be processed by four different directions, thus this workpiece to be processed of automatic accurate location.

Description of drawings

Fig. 1 is the structural representation of the preferred embodiments of the utility model positioner;

Fig. 2 is the side view of positioner shown in Figure 1;

Fig. 3 is the stereogram of positioner shown in Figure 1.

The specific embodiment

To combine the accompanying drawing and the specific embodiment below, the utility model done further describing:

See also Fig. 1-3; The utility model relates to a kind of positioner that is used for locating automatically workpiece to be processed, is provided with first adjacent location-plate 32 of the rectangular-shaped base 53, actuator 80 of cavity, four guide rods 64, plummer 15, two and two adjacent second location-plates 78 in the preferred embodiments of this positioner comprises.In the present embodiment, this workpiece to be processed is a face glass 24.

This base 53 is installed on the lathe workbench of (figure does not show), and can move along with workbench.Four side plates in being located at X-direction and Y direction of this base 53 are installed a bearing 67 respectively, and wherein directions X and Y direction refer to the X axle and the Y direction of rectangular coordinate system respectively.

This actuator 80 is arranged in the cavity of this base 53, the outer sheathed gear 75 of the output of this actuator 80.This actuator 80 is by the controller control of lathe.In the present embodiment, this actuator 80 is a stepper motor.In other embodiments, this actuator also can be rotary cylinder.

Each guide rod 64 is provided with the groove that is complementary with this gear 75, and above-mentioned four guide rods 64 are installed in the corresponding bearing 67 respectively slidably and each guide rod 64 intermeshes through groove and this gear 75.

Two first location-plates 32 are fixed at respectively on the two adjacent ends of guide rod 64 away from this actuator 80, and each location-plate 32 extends a holding division 325 toward the direction of these actuators 80.

Two second location-plates 78 are fixed at respectively on the other two adjacent ends of guide rod 64 away from this actuator 80, and the end face of each second location-plate 78 is provided with two blocking parts 46.

Each first and second location-

plate

32 and 78 with corresponding side plate between also install a guide post 86 so that each first and second location-

plate

32 and 78 can not swing up and down during along with guide rod 64 motions.

This plummer 15 is fixedly set on the end face of this base.In the present embodiment, this plummer 15 is a vacuum adsorption plate.

When needing this face glass 24 of location; Earlier this face glass 24 is positioned on this plummer 15; Then this actuator 80 of the controller of lathe control is through gear 75 each guide rod 64 of direction drive toward this actuator 80; Withstand this face glass 24 until each first location-plate 32 with each blocking part 46, so, can this face glass 24 accurately be located.

When need take out face glass 24; This actuator 80 of controller control of lathe drives each guide rod 64 through gear 75 toward the direction away from this actuator 80; Break away from this face glass 24 until each first location-plate 32 and each location-plate 78; So, can this face glass 24 be taken out from this plummer 15.

For a person skilled in the art, can make other various corresponding changes and distortion, and these all changes and distortion should belong within the protection domain of the utility model claim all according to the technical scheme and the design of above description.
