Abstract

The utility model relates to a centering positioning device for a workpiece installing hole, comprising a base, wherein the base is provided with a lead screw; two sides of the lead screw are respectively provided with a centering disc; the centers of the centering discs are respectively provided with positioning spindles of the same diameter; two sides of the base are also provided with height-adjusting frames and clamping top rods; and four guide sliding blocks are arranged at the front, rear, left and right of a lower bottom plate of the base in parallel. The centering positioning device can carry out centering on the installing holes on a workpiece, simultaneously position the planes of the installing holes at the two sides, thus meeting the requirements of the workpiece on the whole symmetry and the coaxiality of the two sides of the installing holes. The positioning spindles on the centering discs can be replaced, and the installing holes of different sizes can be centered and positioned by replacing the centering spindles of different diameters. The device not only is applicable to processing the moving arms and stick holes of an excavator, but also is suitable for centering and positioning the installing holes of other large workpieces.

Description

A kind of centering positioner that is used for the workpiece installing hole

Technical field

The utility model relates to a kind of device, is specifically related to a kind of centering, positioner.

Background technology

Being processed with than higher requirement of digger operating device will guarantee that promptly there is higher axiality the both sides of each installing hole, and the symmetry to the both sides of integral body has higher requirement again.Existing processing to the digger operating device installing hole is before processing equipment the rule center in each hole, location and the symmetry of both sides, processes on boring machine then; Such method, time-consuming, the trouble of ruling, efficient are low, and the machining accuracy of workpiece is low.

The utility model content

At problems of the prior art, the purpose of this utility model is to propose a kind of centering positioner that is used for the workpiece installing hole, it can be when feeling relieved to the hole on the workpiece, the axiality requirement of workpiece to whole symmetry and installing hole both sides so just satisfied on the plane of location two side holes simultaneously synchronously.

The utility model is achieved through the following technical solutions: a kind of centering positioner that is used for the workpiece installing hole, include base, described base is provided with leading screw, and a centering disk is respectively adorned in the both sides of leading screw, and the identical apotting spindle of a diameter is respectively adorned at the center of centering disk; Also establish the Height Adjustment frame on the described base both sides and clamp push rod, all around is parallel on the lower shoe of described base is equipped with four guide runners.

The utility model is axially felt relieved to work piece by the apotting spindle on the centering disk, the bilateral symmetry location can be carried out to work piece in the side of centering disk, Height Adjustment has been erected the effect of regulating the work piece height, clamps push rod and is used for being fixedly clamped behind the work piece location.Centering disk is that the rotation by leading screw drives its both sides simultaneously by inwardly (or outer) motion of the identical amount of feeding, therefore, its symmetry, axiality is good, and is easy to operate, quick.Apotting spindle on the centering disk can be changed, by changing the apotting spindle of different sizes, can feel relieved, locate the hole of different sizes, promptly this device is general, be specially adapted to the processing in excavator swing arm, dipper hole, also be fit to the centering location of other large-scale workpiece installing holes.

The beneficial effects of the utility model: can locate the plane of two side holes synchronously when felt relieved in the hole on the workpiece, so just satisfy the axiality requirement of workpiece simultaneously to whole symmetry and installing hole both sides.Apotting spindle on the centering disk can be changed, by changing the apotting spindle of different-diameter, can feel relieved, locate the installing hole of different sizes, this device be only applicable to the processing in excavator swing arm, dipper hole, is fit to the centering location of other large-scale workpiece installing holes yet.

Description of drawings

Fig. 1 is the utility model master TV structure schematic diagram;

Fig. 2 is the utility model left side TV structure schematic diagram;

Fig. 3 is the utility model plan structure schematic diagram.

Among the figure 1, base, 2, leading screw, 3, centering disk, 4, the Height Adjustment frame, 5, clamp push rod, 6, apotting spindle, 7,, guide runner.

The specific embodiment

As Figure 1-3, the utility model includes base 1, and leading screw 2 is installed on base, and the both sides of leading screw are respectively adorned a centering disk 3 and are connected with leading screw.Two Height Adjustment framves 4 are installed on the base, can carry out the height of workpiece and regulate.The base both sides are equipped with and are clamped push rod 5, and are parallel with centering disk 3, can clamp the workpiece both sides.Respectively adorn the identical apotting spindle of a diameter 6 (size replaceable) at the center of centering disk 3, all around is parallel on the base lower shoe is equipped with four guide runners 7, is used for and the accurate location of boring table face and parallel the moving on table top thereof.

The utility model in use, on the boring table face, an end of workpiece is put into this device by guide runner 7 positioning and fixing, rotational lead screw drives centering disk 3, and the apotting spindle 6 on the centering disk 3 is penetrated in the workpiece hole, and workpiece is felt relieved; Be rotated further leading screw 2, make the card of two centering disks 3 be close to the two sides of workpiece hole, so just make an end of workpiece carry out accurate location; Look the height situation of other positions of workpiece, use Height Adjustment frame 4 to carry out Height Adjustment,, use 5 pairs of both sides of clamping push rod to be fixedly clamped then to satisfy the whole workpiece position co-ordination.According to the size of workpiece installing hole, the apotting spindle 6 of replaceable different-diameter, promptly this device can position processing to the installing hole of various workpieces.

Claims

1. a centering positioner that is used for the workpiece installing hole includes base (1), it is characterized in that described base is provided with leading screw (2), and a centering disk (3) is respectively adorned in the both sides of leading screw, and the identical apotting spindle of a diameter (6) is respectively adorned at the center of centering disk (3); Also establish Height Adjustment frame (4) on described base (1) both sides and clamp push rod (5), establish guide runner (7) on the lower shoe of base.

2. the centering positioner that is used for the workpiece installing hole according to claim 1 is characterized in that on the lower shoe of described base all around four guide runners (7) that be arranged in parallel.
