Abstract

A multi-spindle drill bit swing-free device mainly comprises a bearing block, a plurality of drill rods, a compressing disk, a positioning disk, a positioning seat and positioning bearings. The drill rods are circumferentially distributed on the bearing block and respectively connected with the bearing block through bearings, cornish bits are mounted on the drill rods respectively, and guide heads are mounted at the front ends of the cornish bits respectively. When a workpiece is processed, the guide heads at the front ends of the cornish bits can directly extend into the positioning bearings to synchronously rotate along with the positioning bearings so as to be kept axially positioned, runout of spindles is prevented, the geometric position tolerance of workpiece holes is ensured, processing accuracy is improved, and product quality is ensured.

Description

A kind of multi spindle drilling head does not have pendulous device

Technical field

The utility model belongs to a kind of technological equipment of special machine bed, and what be specifically related to is that a kind of multi spindle drilling head does not have pendulous device.

Background technology

Wheel industry is a part of automobile industry; Wheel belongs to one-level security personnel parts in the middle of the car load parts; In order to guarantee wheel reliability of products and stability, must need special-purpose process equipment, improve the precision of its processing; It is the special purpose machine tool that guarantees wheel screw hole and the requirement of central hole location degree that porous is bored, and porous is drilled in the detent mechanism that can prevent effectively in the process that the footpath jumping from sliding.

For at present, existing traditional multiaxis drilling machining tool exists radially wobbling of causing because of auger spindle is long all, the aperture deflection of processing, and the geometry in hole and the position degree between the Kong Qun are overproof, influence the vehicle performance index of automobile product.

Summary of the invention

The purpose of the utility model provides a kind of reasonable in design, and is easy to operate, and machining accuracy is high, guaranteed that effectively auger spindle does not have radially that the multi spindle drilling head of position degree does not have pendulous device between the runout and Kong Qun.

The utility model is realized through following technical scheme: a kind of multi spindle drilling head does not have pendulous device, mainly comprises bearing block, drilling rod, compression plate, positioning disk, positioning seat and location bearing.

Along the circumferential direction be distributed with several drilling rods on the said bearing block, and said drilling rod is to be connected with bearing block respectively through bearing, on said drilling rod, is separately installed with cornish bit, the front end of cornish bit is separately installed with guide head.

Compression plate links to each other with bearing block through holddown spring, and passes through the elastic force effect of holddown spring, can transfer compression plate up and down; Positioning disk is a lower end part of being located at compression plate; And positioning seat is the lower end that is anchored on positioning disk; Said several location bearings that in the upper surface of positioning disk, are equipped with the cornish bit coaxial line, in workpiece process, thereby the guide head of cornish bit front end can directly stretch in the location bearing and keeps axial location with location bearing rotation synchronously; Prevent the runout of axle, guaranteed the geometric position degree franchise of workpiece hole.

The beneficial effect of the utility model embodies and is: the Front-end Design through at cornish bit has guide head; And in positioning disk, be provided with location bearing, and the diameter of guide head and the location bearing in the positioning disk are slidingly matched in the axial direction, and the hole retainer shaft of guide head and location bearing is to constant in cornish bit entering cutting overall process; Thereby prevented the runout of axle; Guarantee the geometric position degree franchise of workpiece hole, improved machining accuracy, guaranteed the quality of product.

Description of drawings

Below in conjunction with accompanying drawing the utility model is carried out detailed explanation.

Fig. 1 is the initial position sketch map of cornish bit cutter processing among the utility model embodiment.

Fig. 2 is station one sketch map of cornish bit cutter processing among the utility model embodiment.

Fig. 3 is station two sketch mapes of cornish bit cutter processing among the utility model embodiment.

Be the concrete title of each sign among the figure below: 1 drilling rod, 2 cornish bits, 3 guide heads, 4 location bearings, 5 positioning seats, 6 positioning disks, 7 workpiece, 8 compression plates, 9 holddown springs, 10 bearing blocks.

The specific embodiment

To shown in Figure 3, a kind of multi spindle drilling head does not have pendulous device, mainly comprises bearing block 10, drilling rod 1, compression plate 8, positioning disk 6, positioning seat 5 and location bearing 4 like Fig. 1.

Along the circumferential direction be distributed with several drilling rods 1 on the said bearing block 10, and said drilling rod 1 is to be connected with bearing block 10 respectively through bearing, on said drilling rod 1, is separately installed with cornish bit 2, the front end of cornish bit 2 is separately installed with guide head 3.

Compression plate 8 links to each other with bearing block 10 through holddown spring 9, and passes through the elastic force effect of holddown spring 9, can transfer compression plate 8 up and down; Positioning disk 6 is lower end parts of being located at compression plate 8; And positioning seat 5 is the lower surfaces that are anchored on positioning disk 6; Said several location bearings 4 that in the upper surface of positioning disk 6, are equipped with cornish bit 2 coaxial lines, in workpiece process, thereby the guide head 3 of cornish bit 2 front ends can directly stretch in the location bearing 4 and keeps axial location with location bearing 4 rotation synchronously; Prevent the runout of axle, guaranteed the geometric position degree franchise of workpiece hole.

The operation principle of the utility model is: like Fig. 1, Fig. 2 and shown in Figure 3, wheel spoke workpiece 7 is placed on the positioning disk 6 on the platen face, and the location bearing 4 with cornish bit 2 coaxial lines is installed in the upper end face of positioning disk 6; When the downward drilling feed motion of cornish bit 2; The guide head 3 of cornish bit 2 front ends at first gets in the endoporus of location bearing 4, and along with the downward feed motion of the continuation of cornish bit 2, cornish bit 2 gets into 7 pairs of holes of workpiece and cuts; At this moment; Cornish bit 2 can rotate retainer shaft to fixed synchronously with location bearing 4 inner rings, prevents the runout at the process axis of machining hole, has guaranteed the geometric position degree franchise of workpiece hole; Machining accuracy is high, the favourable position degree that has guaranteed between the Kong Qun.
