Description

Technical Field

[0001] The present invention relates to the technical field of long-axis drilling devices, and particularly relates to a long-axis drilling device convenient for batch processing. Background Art

[0002] In the field of mechanical manufacturing, long-axis parts are widely used. For example, in industries such as automobiles and aerospace, it is often necessary to drill holes in long axes. Currently, most traditional long-axis drilling methods use manual clamping and manual drilling. This method not only has low efficiency but also is difficult to meet the requirements of mass production.

[0003] Moreover, when fixing a long axis, it should be noted that its length is relatively long. If only the two ends of the long axis are fixed, the long axis may bend during drilling, resulting in a lower drilling quality.

[0004] Therefore, we designed a long-axis drilling device convenient for batch processing, which can make the unprocessed long axis automatically descend to the first preset position, and then can stably and safely transfer the unprocessed long axis reaching the first preset position to the arc-shaped placement plate and fix it with high quality, so as to facilitate drilling the outer wall and ends of the long axis, and can transfer the drilled long axis to the blanking place for automatic blanking, and the above operations can be continuously repeated, so as to drill the long axis in batches with high efficiency and high quality.

[0030] Compared with the prior art, the beneficial effects of the present invention include:

[0031] The long axis of the device can be continuously and automatically fed to the first preset position, so that it can be fixedly grabbed by two vertical plates and a horizontal plate and stably conveyed in a C-shaped manner to the arc-shaped placement plate;

[0032] Then the horizontal plate deforms, no longer pressing the two ends of the long axis, but pressing the top of the long axis placed on the arc-shaped placement plate, so that the long axis is stably pressed, avoiding poor drilling effect caused by the long length of the long axis. At this time, the long axis is vertically pressed and fixed, and the long axis will not bend and deform, thus facilitating the opening of holes on its outer wall and ends;

[0033] The long axis after hole opening can be grabbed and conveyed to the conveying inclined plate to be released, so that the processed long axis can be stably and safely unloaded;

[0034] At this time, repeat the operation, so as to drill the long axis in batches;

[0035] The device only uses the first driving motor and the second hydraulic cylinder to drive to realize the above-mentioned automatic feeding of the long axis, automatic feeding of the long axis to the working area, automatic and efficient fixing of the long axis, automatic grabbing and conveying to the unloading area for unloading. The structure is relatively simple, the device is stable, easy to operate, and the maintenance cost is low. Compared with the traditional use of multiple electrical appliances, and the multiple electrical appliances will also cause low service life due to their actions, there is a significant improvement.

At this time, both sides of the bottom long shaft are located at the second notches 47.

[0075] Start the second hydraulic cylinder 29 so that the spline strip 62 on the outer wall of the first spline shaft sleeve 31 is in limited sliding connection within the third spline shaft sleeve 36. At this time, start the first drive motor 26 to drive the first spline shaft 25, the first spline shaft sleeve 31, the spline strip 62, the third spline shaft sleeve 36, the first bevel gear 40, the second bevel gear 41, and the second threaded rod 42 to rotate, thereby driving the cooperating sliding column 15, the vertical plate 18, and the cross plate 19 to perform a U-shaped movement. At this time, the cross plate 19 is exactly placed at the horizontal position at the bottom of the bottom long shaft.

[0076] Then, start the second hydraulic cylinder 29 to disengage the spline bar 62 of the first spline bushing 31 from the third spline bushing 36, and limit the sliding connection of the spline bar 62 on the outer wall of the first spline bushing 31 within the second spline bushing 32. At this time, start the first driving motor 26 to drive the first spline shaft 25, the first spline bushing 31, the spline bar 62, the second spline bushing 32, the first gear 34, the second gear 35, and the first threaded rod 24. Since the two first threaded rods 24 have opposite thread directions, at this time, the two vertical plates 18 fix the two ends of the unprocessed long shaft at the bottom, making the long shaft relatively centered and fixed.

[0077] Then, start the second hydraulic cylinder 29 to disengage the spline bar 62 of the first spline bushing 31 from the second spline bushing 32, and limit the sliding connection of the spline bar 62 of the first spline bushing 31 within the third spline bushing 36. Start the first driving motor 26. At this time, the two vertical plates 18 and the horizontal plate 19 perform a C-shaped movement to safely transfer the long shaft to the arc-shaped placement plate 4.

[0078] Start the second hydraulic cylinder 29 again to disengage the spline bar 62 of the first spline bushing 31 from the third spline bushing 36, and limit the sliding connection of the spline bar 62 on the outer wall of the first spline bushing 31 within the second spline bushing 32. Reverse the first driving motor 26 to release the fixation of the unprocessed long shaft. The long shaft is only fixed at both ends and then placed on the arc-shaped placement plate 4. When drilling the long shaft, the long shaft may bend or be slightly deformed, resulting in a poor processing effect on the long shaft, and the two ends of the long shaft also need to be processed. Therefore, it is necessary to release the pressing and fixation of the two ends of the long shaft. At this time, new pressing fixtures are needed to fix it. Special designs and deformations are carried out for this purpose.

[0079] At this time, start the second hydraulic cylinder 29 to disengage the spline bar 62 of the first spline bushing 31 from the second spline bushing 32, and limit the sliding connection of the spline bar 62 of the first spline bushing 31 within the third spline bushing 36. At this time, start the first driving motor 26 to move the horizontal plate 19 and the vertical plate 18 vertically upward. Then, start the second hydraulic cylinder 29 again to disengage the spline bar 62 of the first spline bushing 31 from the third spline bushing 36, and limit the sliding connection within the second spline bushing 32. At this time, start the first driving motor 26 to place the horizontal plate 19 directly above the long shaft. Then, start the second hydraulic cylinder 29 again to disengage the spline bar 62 of the first spline bushing 31 from the second spline bushing 32, and limit the sliding connection of the spline bar 62 on the outer wall of the first spline bushing 31 within the third spline bushing 36. Start the first driving motor 26 to press down the top of the long shaft with the horizontal plate 19. At this time, the horizontal plate 19 and the arc-shaped placement plate 4 stably fix the long shaft. At this time, drill holes at the end of the long shaft through the drilling machine 16, and drill holes on the outer wall of the long shaft through the drill bit 61. At this time, stable outer wall drilling and end drilling of the long shaft can be achieved, and the drilling quality is good.

[0080] After the drilling is completed, both ends of the long axis after drilling are fixed by the above-mentioned action principle. Then, the long axis after drilling is conveyed to the top of the conveying inclined plate 6. At this time, the long axis after processing is released to slide from the conveying inclined plate 6 onto the L-shaped plate 7, and the operator can take out a batch of long axes that have completed drilling at one time from the material taking port 38.

[0081] Then, the vertical plate 18 and the horizontal plate 19 convey the next unprocessed long axis to the arc-shaped placement plate 4 for processing, and continuously repeat the above actions to drill the outer wall and the end of the long axis in batches with high quality.

[0082] The technical scope of the present invention is not limited to the content described above. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical idea of the present invention, and these deformations and modifications should all fall within the protection scope of the present invention.
