Description

[0002] A hydraulic valve block is an automated component operated by pressurized oil. Controlled by the pressure of a regulating valve, it is typically used in conjunction with a solenoid regulating valve for remote control of the on / off states of oil, gas, and water pipelines in hydropower stations. It serves as both a support plate for other hydraulic components and a conduit for oil circuit connections. The material is generally steel plate or malleable cast iron, and the structure is typically rectangular. During the machining process of a hydraulic valve block, valve holes need to be machined.

[0003] In existing hydraulic valve block machining equipment, the hydraulic valve block is typically clamped first using a positioning fixture, and then a drive assembly drives the drill bit to rotate and drill a hole in the hydraulic valve block. The existing technology has the following problems: metal shavings generated during drilling easily fly in all directions, causing pollution and potentially injuring nearby workers if no protection is provided. Therefore, those skilled in the art have provided a deep-hole machining equipment for hydraulic valve blocks to solve the problems mentioned in the background. Summary of the Invention

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. The lifting protective slag removal component of this application can not only block the flying debris to avoid injuring nearby workers, but also collect the debris to avoid pollution. Specifically, the metal debris generated during the drilling process is blown towards the concave plate by air blowing, and the electromagnet on the concave plate is energized to generate magnetic attraction to collect these metal debris.

[0018] 2. The drive mechanism in this application can raise the blower plate and concave plate to form a barrier during the drilling process, and then lower and hide the blower plate and concave plate after drilling is completed, thereby avoiding affecting the workers' handling of hydraulic valve blocks.

[0019] 3. The positioning mechanism provided in this application can clamp the concave plate after it is raised. The inclined plane will push the three abutting plates to the bottom of the three sides of the concave plate until the abutting plates are pressed against the concave plate and secured, which effectively improves the stability of the concave plate after it is raised.

[0020] 4. The positioning and stabilizing components in this application can secure the hydraulic valve block from above on all four sides during the drilling process. This not only improves the positioning accuracy of the hydraulic valve block but also prevents the drilling accuracy from being reduced due to vibration of the hydraulic valve block during drilling. It should be noted that the positioning fixture on the processing table only secures the lower middle part of the hydraulic valve block, lacking a securing measure for the top of the hydraulic valve block. However, the positioning and stabilizing components in this application can secure the hydraulic valve block from the top, working in conjunction with the positioning fixture to secure the hydraulic valve block from all directions, effectively improving the stability of the hydraulic valve block processing.

[0021] 5. The adjustment mechanism provided in this application can adjust the position of the limit plate according to the specifications and dimensions of the hydraulic valve block, thereby adapting to the processing of different hydraulic valve blocks. At the same time, when the hydraulic valve block is flipped and adjusted to another processing surface, corresponding adjustments can also be made to match it, making it highly applicable.

[0032] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0033] Please see Figures 1-9 In this embodiment of the invention, a deep hole machining equipment for hydraulic valve blocks includes a machine base 1. A fixed plate 2 is fixedly connected to the middle of the top surface of the machine base 1, and a movable machining mechanism is fixedly connected to one side of the top surface of the fixed plate 2. A groove 5 is provided at the edge of the top surface of the machine base 1, and a lifting protective slag removal component is provided inside the groove 5. A column 3 is fixedly connected to the other side of the top surface of the fixed plate 2, and a first motor 15 is fixedly connected to the top of one side of the column 3. A first lead screw 16 is fixedly connected to the bottom output shaft of the first motor 15, and a lifting plate 17 is threadedly connected to the outside of the first lead screw 16. Limiting components are provided on both sides of the lifting plate 17, and a motor base 21 is fixedly connected to one side of the lifting plate 17. A rotary motor 22 is embedded inside the motor base 21, and a connecting shaft 23 is fixedly connected to the bottom output shaft of the rotary motor 22. A positioning and stabilizing component is provided outside the connecting shaft 23, and a drill bit 24 is fixedly connected to the bottom end of the connecting shaft 23. The lifting protective debris removal component not only blocks flying debris to prevent injury to nearby workers, but also collects the debris to prevent pollution.

[0034] In this embodiment, the lifting protective slag removal assembly specifically includes: a blowing plate 6 and a concave plate 7 connected to the blowing plate 6. The blowing plate 6 and the concave plate 7 are movably connected inside the U-shaped groove 5. An electromagnet 38 is embedded in the side of the concave plate 7. An exhaust fan 34 is embedded in one side of the blowing plate 6, and an air blowing hole 39 is embedded in the other side of the blowing plate 6. The air blowing hole 39 is connected to the output end of the exhaust fan 34 and points directly below the drill bit 24. A driving mechanism is provided between the blowing plate 6 and the machine base 1 to drive the blowing plate 6 and the concave plate 7 to rise or fall. A positioning mechanism is provided between the machine base 1 and the electromagnet 38 to improve the stability of the concave plate 7 after it rises. The metal debris generated during the drilling process is blown towards the concave plate 7 by the blowing air, and the electromagnet 38 on the concave plate 7 is energized to generate magnetic attraction and collect these metal debris.

[0035] In this embodiment, the drive mechanism specifically includes two parallel vertical slots 35, which are located on the other side of the blower plate 6. A rack 36 is embedded in the inner wall of each vertical slot 35. A gear 37 is rotatably connected to the inner wall of the U-shaped groove 5 at a position corresponding to the vertical slot 35. A dual-axis motor 40 is embedded between the two gears 37, and the two output shafts of the dual-axis motor 40 are fixedly connected to the two gears 37 respectively. The gears 37 mesh with the corresponding racks 36. This drive mechanism allows the blower plate 6 and the concave plate 7 to be raised to form a barrier during drilling, and then lowered and hidden after drilling is completed, thus avoiding interference with workers' handling of the hydraulic valve block.

[0036] In this embodiment, the positioning mechanism specifically includes: three telescopic grooves 41 formed on the inner wall of the U-shaped groove 5, each telescopic groove 41 corresponding to an inner wall of the concave plate 7, and a matching abutment plate 42 is movably connected inside the telescopic groove 41; a rectangular groove 46 is formed in the middle of the machine base 1, and a cylinder 48 is embedded in the bottom end face of the rectangular groove 46; a ladder 47 is fixedly connected to the top output shaft of the cylinder 48; a strip groove 44 is formed between the telescopic groove 41 and the rectangular groove 46, and a strip plate 45 is movably connected inside the strip groove 44; one end of the strip plate 45 is fixedly connected to the abutment plate 42, and the other end of the strip plate 45 is inclined and matches the ladder 47; two parallel first spring columns 43 are fixedly connected to one side of the abutment plate 42, and one end of the first spring column 43 is fixedly connected to the inner wall of the telescopic groove 41. The positioning mechanism can clamp the concave plate 7 after it is raised. The inclined plane will push the three abutting plates 42 to the bottom of the three sides of the concave plate 7 until the abutting plates 42 are pressed against the concave plate 7 and tightened, which can effectively improve the stability of the concave plate 7 after it is raised.

[0037] In this embodiment, the bottom surface of the groove 5 corresponding to the concave plate 7 is inclined, and the horizontal height of the inclined surface gradually decreases from the side near the blowing plate 6 to the other side. The side of the machine base 1 away from the blowing plate 6 is provided with a slag outlet 8 that communicates with the groove 5. This arrangement facilitates the smooth flow of metal scraps entering the groove 5 out of the slag outlet 8 under their own gravity.

[0038] In this embodiment: the positioning and stabilization component specifically includes: a pressure plate 14, a slot 25 is provided at the center of the top surface of the pressure plate 14, a connecting shaft 23 is inserted into the slot 25 and can move, optical shafts 26 are fixedly connected to both sides of the top surface of the pressure plate 14, and the top of the optical shaft 26 passes through the motor base 21 and is fixedly connected to a limiting head 27, a second spring post 28 is sleeved on the outside of the optical shaft 26, and the two ends of the second spring post 28 are fixedly connected to the pressure plate 14 and the motor base 21 respectively, and a limiting plate 31 is provided at the four periphery of the bottom surface of the pressure plate 14, and an adjusting component is provided between the limiting plate 31 and the pressure plate 14. The positioning and stabilizing components can secure the hydraulic valve block from above on all four sides during drilling, which not only improves the positioning accuracy of the hydraulic valve block, but also avoids the reduction in drilling accuracy caused by the vibration of the hydraulic valve block during drilling. It should be noted that the positioning fixture on the processing table 13 only secures the lower middle part of the hydraulic valve block, and there is no securing measure for the top of the hydraulic valve block. However, the positioning and stabilizing components of this application can secure the hydraulic valve block from the top, and together with the positioning fixture, secure the hydraulic valve block from all directions, effectively improving the stability of the hydraulic valve block processing.

[0039] In this embodiment, the adjusting component specifically includes a T-shaped groove 29 formed on the bottom surface of the pressure plate 14. A T-shaped slider 30 is movably connected inside the T-shaped groove 29, and the bottom end of the T-shaped slider 30 is fixedly connected to a corresponding limiting plate 31. A third spring post 32 is provided on one side of the limiting plate 31, and both ends of the third spring post 32 are fixedly connected to one end of the T-shaped groove 29 and one side of the T-shaped slider 30, respectively. A positioning bolt 33 is provided on the other side of the limiting plate 31, and the positioning bolt 33 is threaded onto the inner wall of one side of the T-shaped groove 29. One end of the positioning bolt 33 abuts against the other side of the T-shaped slider 30. The adjusting component allows the position of the limiting plate 31 to be adjusted according to the specifications and dimensions of the hydraulic valve block, thereby adapting to the processing of different hydraulic valve blocks. Furthermore, it allows for corresponding adjustments when the hydraulic valve block is flipped and adjusted to another processing surface, demonstrating strong applicability.

[0040] In this embodiment, the bottom end of the inner side of the limiting plate 31 is inclined, and the angle between the inclined surface and the horizontal plane is 60 degrees. This setting facilitates the limiting plate 31 to smoothly engage with the top edge of the hydraulic valve block.

[0041] In this embodiment, the limiting component specifically includes two limiting seats 18 fixedly and vertically on one side of the column 3, with a limiting shaft 19 fixedly connected between the two limiting seats 18. A limiting block 20 is fixedly connected to the other side of the lifting plate 17 at a position corresponding to the limiting shaft 19, and the limiting shaft 19 passes through the limiting block 20. The limiting component ensures the stable operation of the lifting plate 17 during its vertical movement. During the rotation of the first lead screw 16, the lifting plate 17, due to the restriction of the limiting block 20 and the limiting shaft 19, can only move up and down along the first lead screw 16.

[0042] In this embodiment, the movable processing mechanism specifically includes: a concave seat 4 fixed to the top surface of the fixed plate 2; a second motor 9 fixedly connected to one side of the concave seat 4; a second lead screw 10 rotatably connected between the inner walls of the two sides of the concave seat 4; the output shaft of the second motor 9 passes through the side wall of the concave seat 4 and is fixedly connected to the second lead screw 10; a traveling seat 12 is threadedly connected to the external side of the second lead screw 10; limit rods 11 are fixedly connected to both sides of the second lead screw 10 and pass through the traveling seat 12; a processing table 13 is fixedly connected to the top of the traveling seat 12; and positioning fixtures are fixedly connected to the four perimeters of the top surface of the processing table 13. The movable processing mechanism can adjust the position of the processing table 13 in the horizontal plane, facilitating the loading and unloading of hydraulic valve blocks and the adjustment of their positions.

[0043] The working principle of this invention is as follows: First, the hydraulic valve block to be processed is placed on the processing table 13 and clamped and fixed by a positioning fixture. Then, the second motor 9 is started to drive the second lead screw 10 to rotate. The traveling seat 12 moves slowly along the second lead screw 10 under the restriction of the limit rod 11 until the processing table 13 on the traveling seat 12 reaches the processing position. At this time, the hydraulic valve block is located directly below the drill bit 24. Then, the lifting protective slag removal assembly operates, lifting the blower plate 6 and the concave plate 7 from the groove 5 through the drive mechanism. Specifically, the dual-axis motor 40 drives two gears 37 to rotate. Since the gears 37 mesh with the rack 36, the blower plate 6 rises along with the rotation of the gears 37. During this process, the concave plate 7 connected to the blower plate 6 rises synchronously.

[0044] After the blower plate 6 and the concave plate 7 are raised, the electromagnet 38 is energized to generate magnetism, and then the positioning mechanism is activated. Specifically, the cylinder 48 extends its output shaft, which drives the ladder 47 to slowly rise along the rectangular groove 46. When the ladder 47 contacts the inclined surface at the end of the strip plate 45, an inclined surface action is generated. As the ladder 47 continues to rise, the strip plate 45 moves slowly under the inclined surface action, which in turn drives the pressing plate 42 in the rectangular groove 46 to move towards the electromagnet 38. During the process, the first spring column 43 is stretched. When the pressing plate 42 contacts the energized electromagnet 38, it is firmly attracted to it, thereby improving the stability of the raised concave plate 7.

[0045] After the positioning mechanism completes the positioning, the drilling work can begin. Specifically, the first motor 15 drives the first lead screw 16 to rotate, and the lifting plate 17 slowly descends along the first lead screw 16 under the limiting action of the limiting component. During the process, the rotary motor 22 drives the connecting shaft 23 and the drill bit 24 to rotate. As the lifting plate 17 descends, the positioning and stabilizing component first contacts the hydraulic valve block. The limiting plate 31 of the positioning and stabilizing component is locked around the four edges of the hydraulic valve block to limit its top. Subsequently, the pressure plate 14 contacts the machining surface of the hydraulic valve block. As the lifting plate 17 descends further, the drill bit 24 on the connecting shaft 23 extends from the slot 25 to drill the hydraulic valve block. It should be noted that during the further descent of the lifting plate 17, the pressure plate 14 always rests against the top surface of the hydraulic valve block. Since there are many holes and slots on the hydraulic valve block, the pressure plate 14 resting against the top of the hydraulic valve block can also block other holes and slots at the top, preventing metal chips from entering these holes and slots during the machining process. During the process, the optical shaft 26 and the motor base 21 undergo relative displacement, and the second spring column 28 is compressed.

[0046] During drilling, the exhaust fan 34 operates, delivering airflow to the air blowing hole 39, which blows it towards the drill bit 24. Metal debris generated around the drill bit 24 is blown towards the concave plate 7. Because the electromagnet 38 on the concave plate 7 is energized and generates magnetism, it effectively attracts and collects this metal debris. After processing is complete, the cylinder 48 of the positioning mechanism retracts its output shaft, causing the platform 47 to descend. The first spring column 43 releases its elastic potential energy, pulling the retaining plate 42 back into the telescopic groove 41. At this point, the retaining plate 42 no longer presses against the concave plate 7. Immediately afterwards, the dual-axis motor 40 of the drive mechanism reverses its direction, causing the air blowing plate 6 and the concave plate 7 to descend. During this process, the metal debris collected by the electromagnet 38 is also carried into the return groove 5. It should be noted that there is a certain gap between the inner side of the groove 5 and the concave plate 7, which is sufficient for the metal debris on the electromagnet 38 to enter the groove 5 smoothly. The inner wall of the groove 5 is made of non-metallic material and will not be attracted and fixed to the electromagnet 38.

[0047] After the metal scraps are carried into the groove 5, the electromagnet 38 loses its electromagnetic properties and the metal scraps that were originally attached to the electromagnet 38 fall to the bottom of the groove 5. In addition, since the bottom surface of the groove 5 corresponding to the concave plate 7 is inclined, the metal scraps that have entered the groove 5 can flow out smoothly from the slag outlet 8 under their own gravity.

[0048] Finally, after the blower plate 6 and the concave plate 7 are lowered and hidden, the first motor 15 reverses its direction, driving the lifting plate 17 to rise, which in turn drives the drill bit 24 and the positioning and stabilizing components to rise synchronously. During this process, the second spring column 28 releases its elastic potential, allowing the pressure plate 14 to continue pressing on the top of the hydraulic valve block when the drill bit 24 is disengaged from the hydraulic valve block, preventing the drill bit 24 from causing the hydraulic valve block to vibrate. After the lifting plate 17 and the positioning and stabilizing components rise to their initial state, the second motor 9 drives the second lead screw 10 to rotate, thereby sending the processing table 13 out, and the operator releases the positioning clamp to remove the hydraulic valve block. In addition, the operator can also flip the hydraulic valve block over for further processing, or replace it with a hydraulic valve block of other specifications for processing. The positioning and stabilizing components can be adjusted adaptively through the adjusting parts, that is, by turning the positioning bolt 33 to push the T-shaped slider 30 in the T-shaped slide groove 29 to the appropriate position, the corresponding limit plate 31 can be driven to the appropriate position, while the third spring column 32 is always in a compressed state, pushing the T-shaped slider 30 towards the positioning bolt 33.

Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
