Description

Technical Field

[0002] The mechanical pump end cover is a component installed at both ends of the mechanical pump to seal the pump cavity and support the rotor. Its main function is to prevent gas leakage in the pump and ensure the stable operation of the rotor. During the production process of the end cover, in order to meet the various needs of the mechanical pump during operation, including ventilation and heat dissipation, lubrication and sealing, monitoring and maintenance, and other special needs, a drilling device is required to process the end cover;

[0003] After drilling holes in the end cover of a mechanical pump using a drilling device, the holes drilled on the surface of the end cover cannot be inspected immediately, and the accuracy of the drilling device gradually decreases due to long-term use or wear, affecting the accuracy and consistency of the drilling. If the holes cannot be detected in time, the accuracy of the drilling device cannot be accurately evaluated, which will not only cause a deviation between the actual size of the aperture and the design size, making it difficult to match the holes on the end cover with other components, increasing the difficulty and time cost of adjustment during assembly, affecting the overall sealing performance of the mechanical pump, and even causing leakage problems. Moreover, if the drilling device works under abnormal conditions for a long time, it will accelerate the wear of its internal components, such as the drill bit, bearings and guide rails, reduce the service life of the drilling device, and further aggravate the problem of decreased accuracy. In addition, the drilling device with decreased accuracy will produce abnormal vibration and noise during the drilling process, making the drilling device more prone to failures, such as drill jamming and drill breakage, posing a safety hazard to the mechanical pump end cover and drilling equipment.

[0024] (III) Beneficial effects

[0025] Compared with the prior art, the present invention provides a drilling device and method for machining a mechanical pump end cover, which has the following beneficial effects:

[0026] 1. Through the drilling detection mechanism, when the drill bit finishes drilling the mechanical pump end cover, the staff can directly drive the detection rod down into the borehole for detection, so that the status of the hole can be understood at the first time. The instant feedback helps to accurately evaluate the accuracy of the drill bit, ensure that the actual size of the hole is consistent with the design size, and reduce deviations. In addition, by timely detecting and adjusting the accuracy of the drilling device, the wear of the drill bit, bearings and guide rail parts can be reduced, thereby extending the service life of the drill bit and the drilling rig body, making the drill bit smoother when drilling, reducing the additional burden on the drilling rig body caused by abnormal vibration and noise, reducing the failure rate of the drill bit (such as drill jamming and drill breakage), and improving work safety;

[0027] Among them, through the provision of the circular ring, spiral block and spiral groove, in the process of driving the detection rod down into the hole, the detection rod can be synchronously driven to rotate, the inner wall of the hole can be polished, and the burrs and scratch defects generated in the drilling process can be removed, which not only improves the smoothness of the inner wall of the hole, reduces the friction and resistance of the mechanical pump end cover during assembly, and improves the assembly efficiency and sealing performance of the mechanical pump end cover, but also the inner wall of the hole is smoother after polishing, and the stress concentration point is reduced, thereby improving the durability and fatigue resistance of the hole, extending the service life of the mechanical pump end cover and other matching parts, and reducing the replacement frequency due to wear.

[0028] 2. By providing the lever, through groove, slider, first spring, fixed column, button and alarm, when the detection rod of the dial plate is lowered into the hole, if the detection rod is blocked or the hole depth is insufficient, the lever will push the slider to drive the fixed column to squeeze the button, turn on the alarm to work, and promptly remind the staff of the abnormality of the hole. The staff can quickly take measures to deal with the abnormality, such as re-drilling and cleaning foreign matter, to prevent potential safety risks and product quality problems, and ensure the smooth progress of the production process. In addition, the detection rod can be buffered when encountering obstructions during the detection process, reduce the mechanical stress of the detection rod when it is blocked, extend its service life, reduce the wear and damage caused by frequent obstructions, and extend the service life of the detection rod.

[0029] 3. Through the detection position calibration mechanism that is set up, the moving position of the detection rod and the lifting distance of the lifting plate above the drill bit can be linked to each other, which not only allows the lifting plate to push the detection rod out from under the drill bit when driving the drill bit to drill a hole in the mechanical pump end cover, thereby avoiding interference with the drill bit and realizing the integrated operation of drilling and detection, but also allows the detection rod to be moved again between the drill bit and the hole when the lifting plate drives the drill bit to rise, and accurately move to the specified position, so that the detection rod can smoothly enter the hole for detection, thereby reducing the problem of inaccurate detection caused by manual operation errors.

[0030] 4. By setting the telescopic plate, central axis, cross plate, sliding column, second spring and disc, when the lifting plate drives the drill bit to process the end cover of the mechanical pump, the cross plate can be synchronously driven to squeeze the second spring, and the rebound force of the second spring can be converted into the clamping force of the limit plate on the end cover of the mechanical pump. The clamping force will gradually increase as the drill bit goes deeper, so that the end cover can be fixed more effectively, the vibration and shaking of the end cover during the drilling process can be reduced, the stability of the drilling can be improved, and it can be ensured that the drill bit can drill smoothly along the predetermined path.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

The drilling detection mechanism includes symmetrically arranged connecting plates 603 and detection rods 602, the number of detection rods 602 is the same as that of the drill bit 4, the connecting plates 603 are symmetrically fixedly connected to the side plates 5 on one side, and the connecting columns 601 are all slidably connected to the side plates 5. The drilling detection mechanism is used for timely detection of the holes drilled by the drill bit 4 on the end cover of the mechanical pump.

[0044] In this embodiment, Figure 3 and Figure 4 As shown, a fixing plate 605 is fixedly connected between the ends of the connecting columns 601 on the same side away from the connecting plate 603, and a circular ring 606 is fixedly connected on both sides of the fixing plate 605.

A spiral groove 610 is provided on the outer surface of the detection rod 602, and a spiral block 611 is fixedly connected to the inner wall of the circular ring 606. The detection rod 602 is threadedly connected to the circular ring 606 through the spiral groove 610 and the spiral block 611. When the detection rod 602 is driven to slide up and down inside the circular ring 606, the detection rod 602 will be affected by the spiral groove 610 and the spiral block 611, and will rotate synchronously during the lifting process.

[0045] In this embodiment, Figure 5 As shown, a lower pressure plate 604 is arranged above the fixed plate 605, and the detection rod 602 is rotatably connected to the lower end surface of the lower pressure plate 604, and the side of the lower pressure plate 604 close to the connecting column 601 is rotatably connected to the connecting rod 607, and the side of the connecting rod 607 away from the lower pressure plate 604 is rotatably connected to the moving block 608, and the moving block 608 is slidably connected to the outer surface of the connecting column 601, and a depth scale bar 609 is provided on the outer surface of the connecting column 601 close to the moving block 608. When the lower pressure plate 604 pushes the detection rod 602 to slide into the hole, the lower pressure plate 604 will push the moving block 608 to slide synchronously on the outer surface of the connecting column 601 through the connecting rod 607. At this time, the staff can understand the position of the detection rod 602 entering the hole by passing through the depth scale bar 609 corresponding to the moving block 608.

[0046] In this embodiment, Figure 5 As shown, the fixed plate 605 is fixedly connected to a support frame 612 at the center of one side near the connecting column 601, and a synchronous motor 616 is fixedly connected to the side wall of the support frame 612. The output end of the synchronous motor 616 is fixedly connected to a dial plate 615, and a dial rod 614 is arranged above the dial plate 615. A sliding groove 613 is opened at the center of one side of the lower pressure plate 604 near the dial rod 614, and the dial rod 614 is slidably connected in the sliding groove 613. When the synchronous motor 616 is turned on to drive the dial plate 615 to rotate, the dial plate 615 will drive the dial rod 614 to slide back and forth horizontally in the sliding groove 613, and make the dial rod 614 drive the lower pressure plate 604 to reciprocate up and down through the sliding groove 613.

[0047] In this embodiment, Figure 5 As shown, the dial plate 615 is provided with a through groove 617, and a slider 618 is slidably connected in the through groove 617. The dial rod 614 is rotatably connected to the slider 618. The lower end surface of the slider 618 is fixedly connected to a fixing column 619, and a button 621 is arranged below the fixing column 619. The button 621 is fixedly connected to the inner side wall of the through groove 617. The button 621 is electrically connected to the alarm 622, and the alarm 622 is fixedly connected to the side wall of the dial plate 615. A first spring 620 is fixedly connected between the side of the slider 618 close to the fixing column 619 and the through groove 617. When the dial plate 615 drives the dial rod 614 to move, if the dial rod 614 is blocked, the slider 618 will be driven to slide in the through groove 617, the first spring 620 will be squeezed, and the fixing column 619 will be driven to press the button 621, so that the alarm 622 is turned on to work.

[0048] In the prior art, after the staff uses the drilling device to process the end cover of the mechanical pump, it is necessary to remove the end cover from the drilling device and use other tools to detect the holes on the end cover. The hole status cannot be reflected in the first time, and the accuracy status of the drilling device cannot be accurately evaluated. Not only will there be a deviation between the actual size of the aperture and the design size, making it difficult to match the holes on the end cover with other components, increasing the difficulty and time cost of adjustment during assembly, affecting the overall sealing performance of the mechanical pump, and even causing leakage problems. Moreover, if the drilling device works under abnormal conditions for a long time, it will accelerate the wear of its internal components, such as the drill bit 4, bearings and guide rails, reduce the service life of the drilling device, and further aggravate the problem of reduced accuracy. In addition, the drilling device with reduced accuracy will produce abnormal vibration and noise during the drilling process. , which makes the drilling device more prone to malfunctions, such as drill jamming and drill breakage, posing a safety hazard to the mechanical pump end cover and the drilling equipment. Compared with the prior art, when the drill bit 4 completes drilling the mechanical pump end cover and rises, the staff can directly drive the detection rod 602 to descend into the borehole for detection, so that the state of the hole can be understood at the first time. The instant feedback helps to accurately evaluate the accuracy of the drill bit 4, ensure that the actual size of the aperture is consistent with the design size, and reduce deviations. In addition, by timely detecting and adjusting the accuracy of the drilling device, the wear on the drill bit 4, bearings and guide rail components can be reduced, thereby extending the service life of the drill bit 4 and the drilling rig body, making the drill bit 4 smoother when drilling, reducing the additional burden on the drilling rig body caused by abnormal vibration and noise, reducing the failure rate of the drill bit 4 (such as drill jamming and drill breakage), and improving work safety.

[0049] In other aspects, this embodiment also provides a detection position calibration mechanism for controlling the moving position of the detection rod 602, such as Figure 1 , Figure 6 and Figure 7 As shown, the detection position calibration mechanism includes a symmetrically arranged push plate 701, one side of the push plate 701 is rotatably connected to the side wall of the lifting plate 3, and the side of the push plate 701 away from the lifting plate 3 is rotatably connected to the upper end surface of the connecting plate 603, and both sides of the connecting plate 603 are rotatably connected with telescopic plates 702, and the center of the telescopic plates 702 on the same side is penetrated and rotatably connected with a central axis 707, and the center of the outer surface of the central axis 707 is fixedly connected with a support plate 706, and the support plate 706 is fixedly connected to the side wall of the side plate 5, and the telescopic plates 702 on the same side are rotatably connected with a cross plate 703 away from the connecting plate 603, and the side of the cross plate 703 close to the side plate 5 is symmetrically provided with sliding columns 704, and the sliding columns 704 are all penetrated and slidably connected to the side plate 5, and the sliding columns 704 on the same side are fixedly connected with the end of the sliding column 704 away from the cross plate 703.

[0050] In this embodiment, Figure 7As shown, the outer surface of the sliding column 704 is fixedly connected with a disk 708, and the side of the disk 708 close to the horizontal plate 703 is fixedly connected with a second spring 709. The end of the second spring 709 away from the disk 708 is fixedly connected to the side wall of the horizontal plate 703. The second spring 709 is sleeved on the outer surface of the sliding column 704, and the sliding column 704 is slidably connected to the horizontal plate 703. When the horizontal plate 703 cannot push the sliding column 704 to move, it will slide on the outer surface of the sliding column 704 to squeeze the second spring 709.

[0051] Compared with the prior art, the moving position of the detection rod 602 and the lifting distance of the lifting plate 3 above the drill bit 4 can be linked to each other, which not only allows the lifting plate 3 to push the detection rod 602 out from under the drill bit 4 when driving the drill bit 4 to descend to drill a hole in the mechanical pump end cover, thereby avoiding interference with the drill bit 4 and realizing the integrated operation of drilling and detection, but also allows the detection rod 602 to be moved again between the drill bit 4 and the hole when the lifting plate 3 drives the drill bit 4 to rise, and accurately move to the designated position, so that the detection rod 602 can smoothly enter the hole for detection, thereby reducing the problem of inaccurate detection caused by manual operation errors.

[0052] In other aspects, this embodiment also provides a drilling method for machining a mechanical pump end cover, such as Figure 1 - Figure 7 As shown, the following steps are included;

[0053] Step 1: Check the drilling device to ensure that all parts are intact and firmly installed;

[0054] Step 2: Place the end cover of the mechanical pump to be processed on the clamping piece of the drilling device so that the center of the end cover is aligned with the center of the drilling mechanism;

[0055] Step 3: Adjust the rotation speed and feed speed parameters of the drilling mechanism according to the material, thickness and required hole size of the mechanical pump end cover;

[0056] Step 4: Drilling the end cover of the mechanical pump to be processed according to preset parameters, and stopping the processing of the end cover of the mechanical pump when the drilling reaches the preset depth;

[0057] Step 5: Clean the drill cuttings and conduct a quality inspection on the processed mechanical pump end cover, including the aperture size, position accuracy, and surface roughness indicators.

[0058] In this embodiment, before processing the mechanical pump end cover in step 4, the drilling device is started to run at no load, and the operation of each component is checked to ensure that there is no abnormal noise or vibration.

[0059] In this embodiment, in step 4, during the drilling process on the end cover of the mechanical pump, coolant is evenly sprayed on the drilling site.

[0060] The working process and principle involved in the overall content of the above embodiment are as follows:

[0061] When the staff needs to drill the mechanical pump end cover, first fix the mechanical pump end cover on the drilling table 1, then move the mechanical pump end cover to just below the drill bit 4, and then adjust the drilling machine body 2 to drive the drill bit 4 to rotate, and at the same time make the drilling machine body 2 push the lifting plate 3 to descend, drive the drill bit 4 at the lower end of the lifting plate 3 to process the mechanical pump end cover below. In the process of the lifting plate 3 descending, the lifting plate 3 will drive the upper ends of the push plates 701 connected to the rotation on both sides to move downward synchronously, and at the same time make the push plate 701 move from an inclined state to a horizontal state. As the state of the push plate 701 changes, the push plate 701 moves downward synchronously. 701 will push the connecting plate 603 away from the side plate 5, and pull the connecting column 601 connected to the connecting plate 603 to slide horizontally on the side plate 5. Since the end of the sliding column 704 away from the connecting plate 603 is connected to the fixed plate 605, the two sides of the fixed plate 605 are connected with the ring 606, and the detection rod 602 passes through the ring 606, so during the horizontal movement of the sliding column 704, the detection rod 602 will be pulled to move synchronously through the fixed plate 605 and the ring 606, so that the detection rod 602 is moved out from under the drill bit 4 to avoid interference with the drill bit 4, thereby realizing the integrated operation of drilling and detection;

[0062] When the connecting plate 603 is affected by the push plate 701 and moves horizontally away from the side plate 5, the connecting plate 603 will drive the upper end of the telescopic plate 702 to move horizontally synchronously, and drive the telescopic plate 702 to rotate on the central axis 707. At the same time, the telescopic plate 702 will shrink and extend during the rotation. When the upper end of the telescopic plate 702 is driven by the connecting plate 603 to rotate with the central axis 707 as the center, the lower end of the telescopic plate 702 will drive the cross plate 703 to move horizontally in the opposite direction, driving the sliding column 704 to slide in the opposite direction on the side plate 5 and the connecting column 601, so that the sliding column 704 pushes the limiting plate 705 to approach the side wall of the mechanical pump end cover under the drill bit 4. When the limiting plate 705 contacts the side wall of the end cover, the drill bit 4 is driven to continue to move deeper as the lifting plate 3 descends. When the drill bit 4 is inserted into the end cover, the lifting plate 3 will use the push plate 701 and the telescopic plate 702 to move the cross plate 703 to squeeze the second spring 709 connected to the outer surface of the sliding column 704. After the second spring 709 is squeezed, the rebound force will be applied to the limit plate 705 through the disc 708 and the sliding column 704, and converted into the holding force of the limit plate 705 on the end cover. As the drill bit 4 continues to descend, the greater the squeezing amplitude of the second spring 709, the greater the rebound force, resulting in the gradual increase of the clamping force of the limit plate 705 on the end cover, so that the end cover can be fixed more effectively, the vibration and shaking of the end cover during the drilling process can be reduced, the stability of the drilling is improved, and it is ensured that the drill bit 4 can drill smoothly along the predetermined path.

[0063] When the drill bit 4 has finished processing the end cover of the mechanical pump, the staff can control the drilling machine body 2 to drive the lifting plate 3 to rise, so that the drill bit 4 and the end cover are separated. During the rising process of the lifting plate 3, the lifting plate 3 will reversely pull the connecting plate 603 close to the side plate 5 through the push plate 701, so that the horizontal plate 703 below the connecting plate 603 is affected by the telescopic plate 702 and the central axis 707, and slides in the opposite direction of the connecting plate 603. The horizontal plate 703 pulls the limiting plate 705 and the side wall of the end cover to separate through the spring, the disc 708 and the sliding column 704, so that the subsequent staff can take the end cover from the drilling table 1;

[0064] When the connecting plate 603 moves in the opposite direction and approaches the side plate 5, the connecting plate 603 will push the detection rod 602 to move between the drill bit 4 and the hole again through the connecting column 601, the fixing plate 605 and the ring 606, and accurately move to the specified position, so that the detection rod 602 can smoothly enter the hole for detection, thereby reducing the problem of inaccurate detection caused by manual operation errors. When the detection rod 602 moves above the drill hole, the staff can turn on the synchronous motor 616 connected to the support frames 612 on both sides to drive the synchronous motor 616 to output The dial plate 615 connected to the output end rotates. As the dial plate 615 rotates, the dial plate 615 will slide the dial rod 614 back and forth in the slide groove 613 opened on the side wall of the lower pressure plate 604 through the slider 618, and the lower pressure plate 604 will be moved up and down through the slide groove 613. During the descent of the lower pressure plate 604, the lower pressure plate 604 will push the detection rod 602 connected to the lower end surface to move downward from the ring 606 until it slides into the drill hole. When the lower pressure plate 604 pushes the detection rod 602 to descend into the drill hole, the lower pressure plate 604 04 will synchronously drive the upper end of the connecting rod 607 to descend, so that the position of the connecting rod 607 changes, and the connecting rod 607 pushes the moving block 608 to slide horizontally on the outer surface of the sliding column 704. Since the outer surface of the sliding column 704 is provided with a depth scale bar 609, when the lower pressure plate 604 pushes the detection rod 602 to slide into the hole, the staff can understand whether the depth of the hole drilled by the drill bit 4 on the end cover meets the standard by penetrating the depth scale bar 609 corresponding to the movement of the moving block 608 on the outer surface of the sliding column 704, so as to be able to Knowing the status of the hole at the first time, instant feedback helps to accurately evaluate the accuracy of the drill bit 4, ensure that the actual size of the hole diameter is consistent with the designed size, reduce deviations, and timely detect and adjust the accuracy of the drilling device to reduce the wear of the drill bit 4, bearings and guide rail components, thereby extending the service life of the drill bit 4 and the drilling rig body, making the drill bit 4 smoother when drilling, reducing the additional burden on the drilling rig body caused by abnormal vibration and noise, reducing the failure rate of the drill bit 4 (such as drill jamming and drill breakage), and improving work safety;

[0065] When the detection rod 602 passes through the ring 606 and descends into the hole, since the outer surface of the detection rod 602 is provided with a spiral groove 610, a spiral block 611 is installed inside the ring 606, and the detection rod 602 is threadedly connected to the ring 606 through the spiral groove 610 and the spiral block 611, as the detection rod 602 descends, the detection rod 602 can rotate synchronously to grind the inner wall of the hole and remove burrs and scratches generated during the drilling process, which not only improves the smoothness of the inner wall of the hole, reduces the friction and resistance of the mechanical pump end cover during assembly, and improves the assembly efficiency and sealing performance of the mechanical pump end cover, but also the inner wall of the hole after grinding is smoother, reducing stress concentration points, thereby improving the durability and fatigue resistance of the hole, extending the service life of the mechanical pump end cover and other matching parts, and reducing the replacement frequency due to wear;

[0066] When the dial plate 615 moves the detection rod 602 down into the hole through the slider 618, the lever 614 and the lower pressure plate 604, if the hole is not deep enough or deviates, the lever 614 will not be able to continue to move the detection rod 602 down through the lower pressure plate 604. At this time, when the dial plate 615 continues to rotate, the lever 614 will push the slider 618 to slide inside the through groove 617 opened on the dial plate 615, and drive the fixed column 619 connected to the slider 618 to press the button 621 connected to the side wall of the through groove 617. 2 is electrically connected, so when the button 621 is pressed, the alarm 622 will be turned on at the same time to remind the staff in time that the hole is abnormal. The staff can quickly take measures to deal with the abnormal situation, such as re-drilling and cleaning foreign matter, to prevent potential safety risks and product quality problems, and ensure the smooth progress of the production process. In addition, it can buffer the obstruction encountered by the detection rod 602 during the detection process, reduce the mechanical stress of the detection rod 602 when it is obstructed, extend its service life, reduce the wear and damage caused by frequent obstructions, and extend the service life of the detection rod 602.
