Technical Field

[0001] The utility model relates to the technical field of water pump casing processing, in particular to a drilling device used for processing water pump casings. Background Art

[0002] A water pump is a machine that transports liquid or pressurizes liquid. It transfers the mechanical energy of the prime mover or other external energy to the liquid, increasing the liquid energy. It is mainly used to transport liquid. The water pump casing is an important component of the water pump. The water pump casing needs to be drilled using a drilling device during processing.

[0003] After searching, the Chinese patent authorization number CN219254200U discloses a drilling device, including a base, a drilling assembly disposed above the base, clamping assemblies disposed on both sides of the upper surface of the base, the clamping assembly including a housing, a bidirectional threaded rod disposed within the housing, second sliders being threadedly connected to the threads at both ends of the bidirectional threaded rod, clamping blocks being fixedly mounted on the upper surfaces of the two second sliders, a drive assembly disposed on one side of the clamping assembly, the drive assembly including a second servo motor, a first rotating drum, a second rotating drum, and a third rotating drum, wherein a transmission belt is rotatably connected between the first rotating drum, the second rotating drum, and the third rotating drum. In the present utility model, the bidirectional threaded rod in the clamping assembly is driven by the drive assembly to rotate in the forward or reverse direction.

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Example

[0026] Reference Figure 1-5 A drilling device used for processing water pump casings includes a base 1, the top of the base 1 is recessed, a placement plate 2 is hingedly connected to the top of the base 1, a clamping portion 3 is provided on the top of the placement plate 2, a discharge port 4 is provided on the top surface of the base 1 located on one side of the placement plate 2, a collecting box 5 is placed just below the discharge port 4, a top groove 6 is provided on the top of the base 1 located below the placement plate 2, the bottom surface of the placement plate 2 is fitted with the top surface of the base 1, and the placement plate 2 covers the top groove 6, an air pump 7 is fixedly connected to one side of the base 1, an adjusting portion 8 is provided in the top groove 6, a top frame 9 is fixedly connected to the top of the base 1, and a drilling assembly is provided on the top wall of the top frame 9.

[0027] A retaining ring 14 is fixedly connected to the top of the placement plate 2 near the edge, and the side of the retaining ring 14 near the discharge port 4 is open. The clamping part 3 includes a hydraulic rod fixedly connected to the inner wall of the retaining ring 14, and the output end of the hydraulic rod is fixedly connected to the clamping plate. A gap is left between the clamping plate and the placement plate 2. The retaining ring 14 can block the waste chips that fall onto the placement plate 2 to prevent the waste chips from bouncing onto the base 1.

[0028] The inner length of the discharge port 4 is gradually reduced from top to bottom, and the top of the collecting box 5 is open.

[0029] like Figure 4-5 As shown, as a preferred embodiment, on the basis of the above method, further, the adjusting part 8 includes a fixed shell 81 fixedly connected to the inner bottom wall of the top groove 6, a piston 82 is slidably connected in the fixed shell 81, the output end of the air pump 7 is connected to a three-way valve 83, one of the output ends of the three-way valve 83 is connected to the lower half of the fixed shell 81, a plurality of springs 84 are fixedly connected between the bottom of the piston 82 and the inner bottom wall of the fixed shell 81, a sliding plate 85 is fixedly connected to the top of the piston 82, the sliding plate 85 passes through the inner top wall of the fixed shell 81, and a round rod 86 is fixedly connected to the top of the sliding plate 85, and the round rod 86 is in contact with the bottom surface of the placement plate 2.

[0030] The three-way valve 83 has an input end and two output ends. The output end of the air pump 7 is connected to the input end of the three-way valve 83. When the spring 84 is in a natural state, the round rod 86 does not press the placement plate 2 upward, and the placement plate 2 is in a horizontal state.

[0031] When you want to clean the waste chips on the placement plate 2, the air pump 7 supplies air toward the lower half of the fixed shell 81, and the air flow pushes the piston 82 to move upward. The piston 82 drives the sliding plate 85 and the round rod 86 to move upward. The round rod 86 pushes the placement plate 2 to rotate, causing the placement plate 2 to tilt. The waste chips on the placement plate 2 slide into the discharge port 4 under the action of gravity, and then fall into the collection box 5.

[0032] like Figure 3As shown, as a preferred embodiment, on the basis of the above method, further, the drilling assembly includes a plurality of electric push rods fixedly connected to the inner top wall of the top frame 9, and the output ends of the plurality of electric push rods are commonly fixedly connected to the driving plate 10, the bottom of the driving plate 10 is installed with a drilling device body 11, the bottom of the driving plate 10 is fixedly connected with a nozzle 12, and one of the output ends of the three-way valve 83 is connected to the nozzle 12 through a hose 13.

[0033] When the drilling device body 11 is working, the output end of the three-way valve 83 connected to the nozzle 12 is opened, and the air pump 7 works so that the air flow enters the nozzle 12 through the hose 13, and then sprays toward the drilled hole on the top of the water pump housing, blowing off the debris on the water pump housing, thereby improving the debris cleaning effect.

[0034] like Figure 4 As shown, as a preferred embodiment, on the basis of the above method, a cavity 15 is further provided in the side of the retaining ring 14 away from the discharge port 4, and a hose 2 16 is fixedly penetrated through the lower half of one side of the fixed shell 81. The hose 2 16 is fixedly passed through the placement plate 2 and the lower half of the retaining ring 14 and extends into the cavity 15. A pressure relief valve 17 is fixedly sleeved on the outer peripheral side of the hose 2 16, and a plurality of nozzles 2 18 are fixedly penetrated through the lower half of one side of the retaining ring 14, and the nozzles 2 18 are communicated with the cavity 15.

[0035] After the piston 82 moves upward until it contacts the top wall of the fixed shell 81, the piston 82 can no longer move, the air pressure in the fixed shell 81 increases, the pressure relief valve 17 opens, the air flow enters the cavity 15 through the hose 16, and then is sprayed toward the top surface of the placement plate 2 through the nozzle 18, blowing the waste chips on the placement plate 2 toward the discharge port 4, thereby further improving the waste chip cleaning effect.

[0036] like Figure 4 As shown, as a preferred embodiment, based on the above-described method, a shock-absorbing pad 19 is further fixedly connected to the upper half of the base 1, and the top surface of the shock-absorbing pad 19 contacts the bottom surface of the placement plate 2. The shock-absorbing pad 19 is made of rubber material. When the air pump 7 is turned off, the piston 82 returns to its original position under the restoring force of the spring 84, and the placement plate 2 returns to its original position under the action of gravity. When the placement plate 2 returns to its original position, it will collide with the shock-absorbing pad 19, thereby preventing the placement plate 2 from suddenly hitting the base 1 and causing large vibrations.

[0037] Specifically, the drilling device used for processing water pump casings is in operation: during drilling operation, the output end of the three-way valve 83 connected to the nozzle 12 is opened, and the other output end is closed, the water pump casing is placed on the placement plate 2, and the water pump casing is fixed by the clamping part 3, and then the drilling assembly works to drill the water pump casing, and at the same time the air pump 7 works, so that the air flow is ejected through the nozzle 12, blowing the drilled hole of the water pump casing, blowing off the debris on the water pump casing, and improving the debris cleaning effect.

[0038] The air flow pushes the piston 82 upward, and the piston 82 drives the sliding plate 85 and the round rod 86 to move upward. The round rod 86 pushes the placement plate 2 to rotate, causing the placement plate 2 to tilt. The waste chips on the placement plate 2 slide into the discharge port 4 under the action of gravity, and then fall into the collection box 5 until the top surface of the piston 82 fits against the top wall of the fixed shell 81. The piston 82 can no longer move. The air pressure in the fixed shell 81 increases, the pressure relief valve 17 opens, and the air flow enters the cavity 15 through the second hose 16, and then is sprayed to the top surface of the placement plate 2 through the second nozzle 18, blowing the waste chips on the placement plate 2 toward the discharge port 4, thereby further improving the waste chip cleaning effect.

[0039] After the debris on the placement plate 2 is cleaned, the air pump 7 is turned off, the piston 82 returns to its original position under the restoring force of the spring 84, and the placement plate 2 returns to its original position under the action of gravity.

[0040] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited to them. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention within the technical scope disclosed by the present invention, and they should be covered by the protection scope of the present invention.
