Description

Portable hole prosthetic devices

Technical Field

The invention relates to the technical field of inner hole repair, in particular to a portable inner hole repair device.

Background

At present, for example, the inner holes of some bearing seats are easy to wear and even damage after a period of operation, and when repairing, the upper half parts of the mounting holes are easy to wear and damage, the bearing seats are usually detached and then the workpiece is fixed on the boring machine by using a traditional boring machine, the spindle rotates to drive the workpiece to rotate, the tool rest moves axially or radially along the workpiece, and a tool arranged on the tool rest is used for cutting the inner holes of the workpiece. However, in enterprises such as chemical plants, shipbuilding plants, steel plants and the like, some workpieces are very large and heavy, disassembly is very difficult, great transportation cost is caused, and a great amount of manpower and material resources are wasted in reassembling. And some workpieces cannot be removed from the apparatus, so that the workpieces cannot be mounted on a conventional boring machine for processing.

In order to achieve the above purpose, the invention is implemented according to the following technical scheme:

The utility model provides a portable hole prosthetic devices, includes two symmetric distributions and is used for pressing from both sides the positioner of the work piece of the hole that waits to repair, connects adjusting screw between two positioner, positioner includes two square inner panels that are parallel and planking, and the area of planking is greater than the area of inner panel, through bolt and nut fixed connection between inner panel and the planking, concentric round hole has been seted up respectively at the center of inner panel and planking, and the planking outer wall can be dismantled and be connected with the sliding sleeve, and the center of sliding sleeve coincides with the center of round hole, four angles of planking have seted up the through-hole respectively, four adjusting screw's both ends pass four through-holes on two positioner's the planking respectively and fasten on the planking with the nut, and all inner panels and planking are parallel to each other, run through the sliding sleeve of two positioner and the hole that wait to repair the work piece between two positioner, pivot and sliding sleeve sliding fit, the outer anchor ring face of pivot is equipped with the boring cutter, pivot one end and the output shaft axial fixed connection of motor, and the motor setting are on the slip feeding device.

Further, the sliding feeding device comprises a base, two sliding rods horizontally fixed on the base and sliding rails in sliding fit with the two sliding rods, and the sliding rails are fixed on the lower end face of the motor.

Still further, a space is left between the inner plate and the outer plate.

Preferably, the outer wall of the sliding sleeve is fixed on the outer wall of the outer plate through bolts.

Compared with the prior art, the invention has simple structure and convenient use, the workpiece of the inner hole to be repaired can be directly clamped by the two positioning devices without detaching the workpiece of the inner hole to be repaired from the equipment, the rotating shaft is inserted into the centers of the two positioning devices and the inner hole of the workpiece of the inner hole to be repaired, then the motor is started to drive the rotating shaft to rotate, the boring cutter on the rotating shaft can bore the inner hole, the motor is arranged on the sliding rail and can control the feeding amount of the rotating shaft, the invention can ensure the concentricity of the workpiece after the inner hole is repaired, and the micrometer can also extend into the bore diameter after the bore hole is measured in real time at the interval between the outer plate and the inner plate.

Detailed Description

The present invention will be described in further detail with reference to the following examples in order to make the objects, technical solutions and advantages of the present invention more apparent. The specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

As shown in fig. 1, this embodiment provides a portable hole repairing device, including two symmetrical distribution be used for pressing from both sides the positioner of the work piece 14 of hole to be repaired, connect adjusting screw 5 between two positioner, positioner includes two square inner panels 2 that are parallel and planking 1, the area of planking 1 is greater than the area of inner panel 2, through bolt 3 and nut 4 fixed connection between inner panel 2 and the planking 1, concentric round hole has been seted up respectively at the center of inner panel 2 and planking 1, planking 1 outer wall is equipped with sliding sleeve 6 with the bolt, the center of sliding sleeve 6 coincides with the center of round hole, four angles of planking 1 have seted up the through-hole respectively, four adjusting screw 5's both ends pass four through the through-holes on two positioner's planking 1 respectively and fasten on planking 1 with nut 4, all inner panel 2 and planking 1 are parallel each other, the inner hole 14 of the hole that is waited to repair between inner hole 6 and two positioner runs through two positioner is provided with pivot 12, pivot 12 and sliding sleeve 6 sliding fit, pivot 12 outer ring face is equipped with concentric round hole, pivot 12 boring tool 13, motor 12 and motor 11 fix on two slide bar 8 and slide bar base 10 at the horizontal base that slide fit.

Of course, in the actual use process, in order to measure the bore diameter of the bore hole in real time, a space is reserved between the inner plate 2 and the outer plate 1, and a measuring tool such as a micrometer can be inserted into the bore hole in the bore hole from the space to measure the inner diameter.

The working principle of the invention is as follows:

The inner plates 2 of the two positioning devices clamp the workpiece 14 of the inner hole to be repaired, the rotating shaft 12 is inserted into the centers of the two positioning devices and the inner hole of the workpiece 14 of the inner hole to be repaired, then the motor 11 is started to drive the rotating shaft 12 to rotate, a boring cutter on the rotating shaft 12 can bore the inner hole, in the boring process, the motor can slide on the slide rod 9 by manual sliding so as to control the feeding amount of the rotating shaft 12, thus the inner hole of the workpiece 14 of the inner hole to be repaired can be enlarged, then a machined bushing is inlaid in the inner hole, the inner hole of the bushing is machined again, and when the inner hole of the bushing is machined, the inner diameter is measured by measuring tools such as a micrometer extending into the inner hole after boring from the interval in real time, so that the inner hole after the bushing is repaired to the precision required by design.

The technical scheme of the invention is not limited to the specific embodiment, and all technical modifications made according to the technical scheme of the invention fall within the protection scope of the invention.
