Description

Technical Field

[0001] The invention relates to the technical field of boring equipment, in particular to a bidirectional positioning automatic boring equipment. Background Art

[0002] Boring machines are equipment specially used for processing deep hole workpieces such as oil cylinders, gas cylinders, hydraulic cylinders, etc. They can also process the spindle holes, blind holes and stepped holes of machine tools. Boring equipment can not only undertake various drilling and boring operations, but also perform rolling operations. Internal or external chip removal methods are used during drilling. When boring larger holes, it is generally necessary to bore from the center first, then gradually adjust the position of the tool bar, and expand the hole outward multiple times until the inner diameter of the hole reaches the required size. This can reduce the resistance during a single feed, improve the smoothness of boring, and extend the service life of the tool.

[0003] When using the existing boring equipment, the outer wall of one end of the workpiece is generally fixed by a clamping mechanism, and the workpiece is driven to continuously squeeze close to the position of the cutter head during rotation to achieve the purpose of single-sided boring. When the workpiece is long and has holes at both ends, when the existing boring equipment fixes the workpiece, if only the outer wall of one end of the workpiece is clamped and driven to rotate, the other end is prone to axial deviation during rotation, resulting in deviations in the size of the hole during the boring process. At the same time, the efficiency of boring is low when boring a single-sided hole for such a long workpiece. To this end, we propose a bidirectional positioning automatic boring equipment.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention provides a bidirectional positioning automated boring device, which solves the problem that the existing boring device is difficult to synchronously perform automatic positioning and boring operations on both ends of a workpiece when in use. The driving motor is started to make the outer gear ring drive the workpiece to rotate, and the second gear drives the reciprocating screws at both ends to rotate, so that the driving block slides back and forth in the guide frame. When the driving block moves toward one side of the outer gear ring, it pulls the second spring to make the sliding seat slide toward the adjustment plate, and the sliding seat drives the mounting frame and the mounting block to make the tool rod slide toward one side of the workpiece to perform boring. The second spring has a certain degree of buffering, which can slow down the feed speed when the boring resistance is large, and increase the feed thrust until the sliding seat moves to a position that fits and contacts the side of the adjustment plate.

[0015] 2. The present invention provides a bidirectional positioning automatic boring equipment. When the driving block slides toward one side of the side plate, the second spring will be retracted and reset first, and then the second spring will continue to be pushed to be squeezed, so that the sliding seat slides in the opposite direction, and the fixed rod is gradually inserted into the mounting frame, so that the second bevel gear block pushes the first bevel gear block to rotate, and the first bevel gear block drives the driving disk to rotate, so that the first threaded rod rotates a certain angle, driving the mounting block and the tool rod to move up a set distance, and then the sliding seat slides in the opposite direction again, and the mounting frame moves away from the fixed rod, which will not drive the first bevel gear block and the driving disk to rotate in the opposite direction, thereby ensuring that the mounting block will be driven to move up a set distance each time the mounting frame slides back and forth. The adjustment is automatically controlled and does not require a motor to drive, thereby reducing costs.

[0016] 3. The present invention provides a bidirectional positioning automated boring equipment. When the top of the mounting block moves up to a position where it conflicts with the bottom of the lifting block, the mounting block cannot continue to move up, and the first threaded rod cannot continue to rotate to that side. When the driving block pushes the second spring to make the sliding seat slide toward the side plate, the second bevel gear block will conflict with the first bevel gear block and remain stationary. At this time, the driving block continues to compress the second spring, and the position of the mounting frame does not change until the driving block slides away from the side plate again. The second spring can be pulled again to make the mounting frame slide toward the side of the workpiece together with the tool rod, completing the step-by-step boring operation. At this time, the position of the tool rod has moved to the maximum inner diameter. When the driving block reaches a position close to the side plate next time, the overall boring operation is completed. BRIEF DESCRIPTION OF THE DRAWINGS

The driving mechanism 4 is used to drive the reciprocating screw 25 to rotate, and a control member 28 for presetting the moving position of the sliding seat 8 is provided on the guide frame 3.

[0024] The control member 28 includes a third threaded rod 29 rotatably connected to the side plate 17. The third threaded rod 29 is rotatably connected to the guide frame 3 on the side away from the side plate 17. An adjustment plate 30 is slidably connected to the guide frame 3 in a horizontal direction. The third threaded rod 29 penetrates the adjustment plate 30 and the sliding seat 8 and is threadedly connected to the adjustment plate 30.

Indicator blocks 36 are respectively fixedly connected to the sides of the lifting block 14 and the adjustment plate 30.

[0025] The driving mechanism 4 also includes a driving motor 31 fixedly mounted on the body 1. The model of the driving motor 31 is preferably Y80M1-2. The output end of the driving motor 31 is coaxially fixedly connected to the first gear 32. A second gear 33 meshing with the first gear 32 is rotatably connected to the body 1. The end of the reciprocating screw 25 away from the side plate 17 is coaxially fixedly connected to the side of the second gear 33. The second gear 33 meshes with the outer gear ring 5. An annular frame 34 is fixedly connected to the guide frame 3. The two sides of the outer gear ring 5 are rotatably connected to the two groups of annular frames 34 respectively.

[0026] In this embodiment, the workpiece 41 is passed through the outer gear ring 5, the electric telescopic rod 39 is controlled to push the clamping block 40 to clamp and fix the outer wall of the workpiece 41, the second threaded rod 15 is rotated to drive the lifting block 14 to lift and slide, and the corresponding position of the indicator block 36 on the lifting block 14 and the scale groove 35 on the mounting frame 9 is observed, so that the lifting block 14 is moved to the required position, and the preliminary examination of the inner diameter size of the hole can be completed. At the same time, the third threaded rod 29 is rotated to drive the adjustment plate 30 to slide horizontally, and the corresponding position of the indicator block 36 on the adjustment plate 30 and the scale groove 35 on the guide frame 3 is observed, so that the adjustment plate 30 is moved to the required position, and the preset depth of the hole can be completed. The tool rod 2 of the required size is inserted into the butt tube 37, and the tool rod 2 is fixed by the fixing buckle 38 to complete the replacement and installation of the tool rod 2.

[0027] The driving motor 31 is started to drive the first gear 32 to rotate, and the first gear 32 drives the second gear 33, so that the outer gear ring 5 drives the workpiece 41 to rotate, and the second gear 33 drives the reciprocating screws 25 at both ends to rotate, so that the driving block 26 slides back and forth in the guide frame 3. When the driving block 26 moves to one side of the outer gear ring 5, it will pull the second spring 27, so that the sliding seat 8 slides toward the adjusting plate 30, and the sliding seat 8 drives the mounting frame 9 and the mounting block 11 to make the tool rod 2 slide toward the side of the workpiece 41 to bore the hole. The second spring 27 has a certain degree of buffering, which can slow down the feed speed and increase the feed thrust when the boring resistance is large. In the process of the driving block 26 moving to the maximum displacement, the second spring 27 is continuously pulled until the sliding seat 8 moves to a position that fits and contacts the side of the adjusting plate 30. After that, the sliding seat 8 cannot continue to move to this side, indicating that the hole has been bored to the maximum depth. The second spring 27 is continuously stretched until the driving block 26 slides in the opposite direction from one end.

[0028] When the driving block 26 slides to one side of the side plate 17, the second spring 27 will be retracted and reset first, and then the second spring 27 will continue to be pushed to squeeze, so that the sliding seat 8 slides in the opposite direction, the tool rod 2 gradually moves out from the inside of the workpiece 41, and the fixing rod 20 is gradually inserted into the mounting bracket 9, so that the second bevel gear block 23 pushes the first bevel gear block 21 to rotate, and the first bevel gear block 21 drives the driving disk 19 to rotate, thereby making the first threaded rod 13 rotate a certain angle, driving the mounting block 11 and the tool rod 2 to move up a set distance together, and then the sliding seat 8 slides in the opposite direction again, and the mounting bracket 9 moves away from the fixing rod 20. At this time, the inclined surface of the second bevel gear block 23 is in contact with the inclined surface of the first bevel gear block 21, so that the second bevel gear block 23 is pushed into the sliding groove 22, compressing the first spring 24, and will not drive the first bevel gear block 21 and the driving disk 19 to rotate in the opposite direction, which can ensure that the mounting block 11 will be driven to move up a set distance each time the mounting bracket 9 slides back and forth. The adjustment is automatically controlled, does not need to be driven by a motor, and reduces costs.

[0029] When the top of the mounting block 11 moves up to the position that conflicts with the bottom of the lifting block 14, the mounting block 11 cannot continue to move up, and the first threaded rod 13 cannot continue to rotate to that side, and the driving plate 19 and the first bevel gear block 21 cannot rotate. When the driving block 26 pushes the second spring 27 to make the sliding seat 8 slide toward the side plate 17, the first bevel gear block 21 cannot be further pushed by the second bevel gear block 23, and the second bevel gear block 23 will conflict with the first bevel gear block 21 and remain stationary. At this time, the driving block 26 continues to compress the second spring 27, and the position of the mounting frame 9 does not change until the driving block 26 slides away from the side plate 17 again, and the second spring 27 can be pulled again to make the mounting frame 9 slide toward the side of the workpiece 41 together with the tool rod 2, completing the step-by-step boring operation. At this time, the position of the tool rod 2 has moved to the maximum inner diameter, and when the driving block 26 reaches the position close to the side plate 17 next time, the overall boring operation is completed.

[0030] The boring structures on both sides of the outer gear ring 5 of the device are the same, but can be adjusted separately, so that the hole depth and inner diameter at both ends of the workpiece 41 can be freely adjusted and are not necessarily exactly the same. At the same time, synchronous operation is achieved during operation, which reduces driving costs and makes the structural operation more stable, making the force at both ends of the workpiece 41 more uniform and stable, thereby improving the efficiency of boring.

[0031] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
