Description

Technical Field

[0001] The invention relates to the technical field of drilling equipment, in particular to a drilling equipment for producing and processing shaft parts. Background Art

[0002] In the field of shaft parts processing, drilling equipment is key equipment for achieving precise parts processing. The drilling equipment for shaft parts production and processing provided by the present invention realizes automatic positioning, fixation, and drilling operations of shaft parts through the coordinated design of the punching mechanism and the stabilization mechanism. Its core lies in utilizing the air pressure generated by the extrusion of the bellows to drive the No. 1 and No. 2 telescopic rods, and in conjunction with the retractable No. 1 and No. 2 plug-in boards and the elastic clamping structure, to achieve adaptive fixation and stable drilling of shaft parts of different diameters, which is suitable for large-scale high-precision processing scenarios of shaft parts.

[0003] Traditional drilling equipment for shaft parts has significant shortcomings. In terms of automation, traditional equipment relies on manual fixation of shaft parts, which is cumbersome and inefficient, making it difficult to adapt to mass production needs. Compatibility is poor, and the fixing fixtures are mostly rigid structures that cannot automatically adjust according to the diameter of shaft parts. Frequent fixture replacement is required, increasing production costs and downtime. Insufficient stability and the lack of a secondary fixing mechanism for parts can easily lead to hole position deviations due to part jitter during drilling, which has a significant impact on the processing accuracy of parts with a large aspect ratio. In addition, the traditional clamping method has insufficient friction, and the rubber plate has a small contact area, making it difficult to resist vibrations during the drilling process, resulting in slight displacements of the parts affecting the processing accuracy, and unable to achieve targeted support for the drilling area, which restricts the quality and efficiency of drilling shaft parts. Summary of the Invention

The No. 1 plug-in plate and the No. 2 plug-in plate are combined into a circular ring shape, and the outer surface of the No. 2 plug-in plate is initially in contact with the inner surface of the mounting ring.

[0011] According to one embodiment of the present invention, a No. 1 telescopic rod is fixedly connected to the outer surface of the mounting ring through which the No. 1 telescopic rod is passed. Four No. 1 telescopic rods are arranged on the same mounting ring along its central axis at fixed intervals, wherein the No. 1 telescopic rod is arranged between two adjacent connecting covers. The output end of the No. 1 telescopic rod is fixedly connected to the outer surface of the No. 2 plug-in board. The end of the No. 1 telescopic rod away from the mounting ring passes through and is fixedly connected to a connecting ring, wherein the four No. 1 telescopic rods on the same mounting ring are connected to each other through the connecting ring.

[0012] According to one embodiment of the present invention, the bottom outer surface of the support rod is fixedly sleeved with a bottom ring, the upper surface of the bottom ring is fixedly connected with a bellows, the bellows is sleeved on the outside of the support rod, the top of the bellows is fixedly connected with a top ring, and the top ring is slidably sleeved on the top outer surface of the support rod, wherein the top ring is arranged below the slider, and the bottom of the bellows is connected to the internal cavity of the connecting ring through a hose.

[0013] According to one embodiment of the present invention, the stabilizing mechanism includes a No. 2 telescopic rod, which is fixedly connected to the bottom outer surface of the support rod, wherein the No. 2 telescopic rod is arranged below the bottom ring, and the No. 2 telescopic rods on the two support rods are arranged opposite to each other, and the outer surface of the No. 2 telescopic rod away from one end of the support rod is fixedly sleeved with a ring, and the bottom of the ring is fixedly connected to the upper surface of the base through a connecting rod and the upper surface of the slide.

At this time, as the connecting frame and the slider move downward, the top ring is squeezed by the slider, causing the top ring to slide down along the support rod, and then start to squeeze the corrugated tube.

[0016] (3) Beneficial effects

[0017] The present invention provides a drilling device for the production and processing of shaft parts. It has the following beneficial effects:

[0018] (1) The drilling equipment for producing and processing shaft parts, when the bellows is squeezed, its internal air pressure will be transmitted to the No. 1 telescopic rod, that is, the internal air pressure of the No. 1 telescopic rod will increase, so that the output end of the No. 1 telescopic rod will begin to squeeze outward, that is, it will begin to push the No. 1 plug-in board and the No. 2 plug-in board to start to shrink in a circle, and finally the inner surface of the No. 2 plug-in board will be squeezed and fit on the outer surface of both ends of the shaft part to fix it, thereby realizing automatic fixation of both ends of the shaft part when the drilling machine moves down to prepare for drilling the shaft part, compared with the current drilling equipment that requires manual operation to manually fix the shaft part The problem of fixation is solved, which greatly improves the degree of automation of this equipment. At the same time, the combination of the retractable No. 1 plug-in board and the No. 2 plug-in board allows this equipment to match shaft parts of different diameters, greatly improving the applicability of this equipment to match and complete the drilling processing of shaft parts of multiple sizes. At the same time, the internal air pressure of the No. 1 telescopic rod on the two mounting rings is automatically balanced by air pressure, so that this equipment can automatically balance the air pressure to achieve a good fixing effect when drilling shaft parts of different diameters at both ends, avoiding the problem of frequent replacement of fixtures in existing drilling equipment, and further improving the applicability of this equipment.

[0019] (2) The drilling equipment for producing and processing shaft parts, as the bellows is squeezed, will simultaneously transmit its internal air pressure to the inside of the No. 2 telescopic rod, causing the output ends of the two No. 2 telescopic rods to approach each other, and then drive the two mounting rods to approach each other, that is, finally making the two mounting plates squeeze and fit on both sides of the shaft part, thereby achieving preliminary fixation of the shaft part by the No. 1 plug-in plate and the No. 2 plug-in plate when drilling, and finally completing the secondary fixation of the shaft part by squeezing the mounting plates, automatically clamping and fixing both sides of the drilling part, avoiding the problem of drilling accuracy caused by the shaking of the shaft part due to length problems during drilling, and when the drilling is completed, the drilling machine moves up, and at this time the mounting plate and the No. 1 plug-in plate and the No. 2 plug-in plate gradually break away from the squeezing of the shaft part, that is, facilitating the rapid position adjustment of the shaft part, and facilitating the rotation adjustment of the shaft part when drilling.

[0020] (3) In the drilling equipment for producing and processing shaft parts, a clamping plate is provided on the outer side of the mounting plate, that is, as the two mounting rods approach each other, the clamping plate and the rubber plate are squeezed and fitted on the outer surface of the shaft part, and the friction between the clamping plate and the shaft part is greatly enhanced by the rubber plate, thereby avoiding drilling accuracy problems caused by slight flipping of the shaft part due to vibration during the drilling process. At the same time, when the clamping plate begins to squeeze and fix the shaft part, it will move closer to the mounting plate through the sliding plate, that is, the extrusion bag between the mounting plate and the clamping plate is squeezed and deformed, and its internal air pressure is transmitted to the elastic expansion plates at both ends of the mounting plate, prompting the elastic expansion plates to expand outward, that is, it begins to squeeze the two ends of the clamping plate closer to each other and shrink, so that the clamping plate automatically shrinks its two ends when it is squeezed on both sides of the shaft part, greatly increasing the fitting area of the rubber plate and the shaft part, that is, increasing the friction between the clamping plate and the shaft part, further ensuring the stability of drilling, and avoiding the problem that when the diameter of the shaft part is small, the contact area between the rubber plate on the clamping plate and the outer surface of the shaft part is too small to achieve a good fixing effect.

[0034] The punching mechanism 2 includes a slide rod 21, which is symmetrically fixedly connected to the inner surfaces of both sides of the base 1. A slide seat 22 is slidably sleeved on the slide rod 21, and a support rod 23 is fixedly connected to the upper surface of the slide seat 22 away from the base 1. The support rod 23 is symmetrically arranged on both sides of the base 1, and a slider 24 is slidably sleeved on the support rod 23. The side surface of the slider 24 is fixedly connected to a connecting frame 25, and a drilling machine 26 is fixedly connected to the middle part of the connecting frame 25. The drilling machine 26 and the central axis of the base 1 are in the same vertical plane.

[0035] Mounting rings 27 are symmetrically fixedly connected to the upper surfaces of both sides of the base 1 , wherein the two mounting rings 27 are arranged on the same central axis, and the central axes of the two mounting rings 27 and the central axis of the drilling machine 26 are arranged in the same vertical plane.

[0036] The outer surface of the mounting ring 27 is fixedly connected to a connecting cover 28 , and four connecting covers 28 are arranged on the same mounting ring 27 at fixed intervals along its central axis. The inner surface of the connecting cover 28 is fixedly connected to a limiting rod 29 , and the end of the limiting rod 29 away from the connecting cover 28 passes through the mounting ring 27 .

[0037] The limiting rod 29 is slidably connected to the No. 1 plug-in board 210 through a spring, and the two ends of the No. 1 plug-in board 210 are slidably plugged with the No. 2 plug-in board 211. The No. 1 plug-in board 210 and the No. 2 plug-in board 211 are combined into a circular ring shape, and the outer surface of the No. 2 plug-in board 211 is initially in contact with the inner surface of the mounting ring 27.

[0038] A number one telescopic rod 212 is fixedly connected to the outer surface of the mounting ring 27 through which it passes. Four number one telescopic rods 212 are arranged on the same mounting ring 27 along its central axis at fixed intervals. The number one telescopic rod 212 is arranged between two adjacent connection covers 28. The output end of the number one telescopic rod 212 is fixedly connected to the outer surface of the number two plug-in board 211. The end of the number one telescopic rod 212 away from the mounting ring 27 passes through and is fixedly connected to a connecting ring 213. The four number one telescopic rods 212 on the same mounting ring 27 are connected to each other via the connecting ring 213.

[0039] The bottom outer surface of the support rod 23 is fixedly sleeved with a bottom ring 214, the upper surface of the bottom ring 214 is fixedly connected with a bellows 215, the bellows 215 is sleeved on the outside of the support rod 23, the top of the bellows 215 is fixedly connected with a top ring 216, and the top ring 216 is slidably sleeved on the top outer surface of the support rod 23, wherein the top ring 216 is arranged below the slider 24, and the bottom of the bellows 215 is connected to the internal cavity of the connecting ring 213 through a hose.

[0040] Second embodiment: Figures 1 to 8 As shown, the stabilizing mechanism 3 includes a No. 2 telescopic rod 31, which is fixedly connected to the bottom outer surface of the support rod 23, wherein the No. 2 telescopic rod 31 is arranged below the bottom ring 214, and the No. 2 telescopic rods 31 on the two support rods 23 are arranged opposite to each other, and the outer surface of the No. 2 telescopic rod 31 away from one end of the support rod 23 is fixedly sleeved with a ring 32, and the bottom of the ring 32 is fixedly connected to the upper surface of the base 1 through a connecting rod and the upper surface of the slide 22.

[0041] The end of the second telescopic rod 31 away from the support rod 23 is fixedly connected to the mounting rod 33, and the two ends of the mounting rod 33 are symmetrically fixedly connected to the mounting plates 34. The mounting plates 34 are arranged in an arc shape, and the outer surface of the mounting plate 34 is symmetrically penetrated by a sliding plate 35 that is slidably connected. The end of the sliding plate 35 away from the mounting plate 34 is fixedly connected to a clamping plate 36. The clamping plate 36 is arranged in an arc shape, and the inner surface of the clamping plate 36 is fixedly inlaid with a rubber plate 37.

[0042] The outer surfaces of the upper and lower ends of the mounting plate 34 are symmetrically fixedly connected with elastic telescopic plates 38, and the elastic telescopic plates 38 are arranged in an arc shape. The output ends of the elastic telescopic plates 38 are fixedly connected to the outer surfaces of the upper and lower ends of the clamping plate 36, and the inner surface of the mounting plate 34 is fixedly connected with an extrusion bag 39. The outer surface of the side of the extrusion bag 39 away from the mounting plate 34 is fixedly connected to the surface of the clamping plate 36 close to the mounting plate 34, wherein the internal cavity of the extrusion bag 39 is connected to the internal cavity of the elastic telescopic plate 38.

[0043] During operation, the shaft parts are placed through the mounting ring 27 and the drilling machine 26 is started. Then, the connecting frame 25 is driven to drive the drilling machine 26 to move down along the support rod 23 through the slider 24 and approach the shaft parts until the drilling machine 26 contacts the shaft parts and drills holes to complete the drilling needs of the shaft parts. The shaft parts passing through the two mounting rings 27 means that the shaft parts are on the inner sides of the No. 1 plug-in plate 210 and the No. 2 plug-in plate 211. At this time, as the connecting frame 25 and the slider 24 move downward, the top ring 216 is squeezed by the slider 24, causing the top ring 216 to slide down along the support rod 23, and then the bellows 215 is squeezed. When the bellows 215 is squeezed, its internal air pressure is transmitted to the No. 1 telescopic rod 212, The internal air pressure of the No. 1 telescopic rod 212 increases, so that the output end of the No. 1 telescopic rod 212 begins to squeeze outward, that is, it begins to push the No. 1 plug-in board 210 and the No. 2 plug-in board 211 to start to shrink in a circle. Finally, the inner surface of the No. 2 plug-in board 211 is squeezed and fits against the outer surfaces of both ends of the shaft part to fix it, thereby automatically fixing the two ends of the shaft part when the drilling machine 26 moves down to prepare for drilling the shaft part. Compared with the problem that the current drilling equipment requires manual operation to manually fix the shaft part, the degree of automation of this equipment is greatly improved. At the same time, the combination of the retractable No. 1 plug-in board 210 and the No. 2 plug-in board 211 can make this equipment compatible with shaft parts of different diameters, greatly improving the applicability of this equipment. The bellows 215 is squeezed to convey the air pressure inside the second telescopic rod 31, causing the output ends of the two second telescopic rods 31 to approach each other, thereby driving the two mounting rods 33 to approach each other, that is, finally causing the two mounting plates 34 to be squeezed and fitted on both sides of the shaft part, thereby achieving a good fixing effect when drilling shaft parts with different diameters at both ends. The first plug-in plate 210 and the second plug-in plate 211 are used to preliminarily fix the shaft parts, and finally the secondary fixation of the shaft parts is completed by squeezing the mounting plate 34, and the two sides of the drilling part are automatically clamped and fixed, so as to avoid the drilling accuracy problem caused by the shaking of the shaft parts due to the length problem during drilling. When the drilling is completed, the drilling machine 26 moves up, and the mounting plate 34 and the first plug-in plate 210 and the second plug-in plate 211 gradually break away from the squeezing of the shaft parts, which is convenient for the rapid position adjustment of the shaft parts and is conducive to the need to rotate the shaft parts to adjust the drilling position. A clamping plate 36 is provided on the outside of the mounting plate 34, that is, as the two mounting rods 33 approach each other, the clamping plate 36 and the rubber plate 37 are squeezed and fitted on the outer surface of the shaft parts.The rubber plate 37 greatly enhances the friction between the clamping plate 36 and the shaft part, avoiding drilling accuracy problems caused by slight flipping of the shaft part due to vibration during the drilling process. At the same time, when the clamping plate 36 begins to squeeze and fix the shaft part, it will move closer to the mounting plate 34 through the sliding plate 35, causing the squeezing bag 39 between the mounting plate 34 and the clamping plate 36 to be squeezed and deformed, and its internal air pressure is transmitted to the elastic expansion plates 38 at both ends of the mounting plate 34, causing the elastic expansion plates 38 to expand outward, that is, starting to squeeze the two ends of the clamping plate 36 closer to each other and contract, so that the clamping plate 36 automatically contracts when it is squeezed on both sides of the shaft part, greatly increasing the contact area between the rubber plate 37 and the shaft part, that is, increasing the friction between the clamping plate 36 and the shaft part, further ensuring the stability of the drilling, and avoiding the problem that when the diameter of the shaft part is small, the contact area between the rubber plate 37 on the clamping plate 36 and the outer surface of the shaft part is too small to achieve a good fixing effect.
