Description

Technical Field

[0001] The invention belongs to the technical field of centrifugal pump accessory processing, and in particular relates to a centrifugal pump impeller cover plate processing device. Background Art

[0002] The impeller of a centrifugal pump usually consists of blades and front and rear cover plates. The impeller cover plates are divided into front cover plates and rear cover plates. The front cover plate is located on the inlet side of the impeller. Its main function is to form a flow channel together with the rear cover plate to guide the liquid to flow in the impeller and reduce liquid leakage losses. The rear cover plate is on the outlet side of the impeller. It and the front cover plate together support the blades to ensure the structural stability of the impeller when rotating at high speed. At the same time, the rear cover plate also helps to improve the hydraulic efficiency of the impeller.

[0003] In the prior art, methods for deburring the surface of impeller cover plates made of metal materials generally include manual deburring, mechanical deburring, chemical deburring, electrolytic deburring and ultrasonic deburring. For centrifugal pump impeller cover plates with complex internal shapes, ultrasonic technology is generally used for burr removal. In actual application, the impeller cover plates to be burred are generally sent to an ultrasonic processing device for static treatment, and the burrs are removed by ultrasonic vibration. Although this method can fully remove the burrs of the impeller cover plates, there are certain inconveniences in the operation of sending the impeller cover plates into the ultrasonic processing device and taking them out, and the connection is poor. In addition, when the impeller cover plates are sent for ultrasonic deburring treatment, some tiny particles peeled off from the burrs may remain on the surface of the impeller cover plates during the burr removal process. The static method increases the possibility of tiny particles remaining, thereby greatly increasing the difficulty of rinsing after ultrasonic deburring treatment.

[0004] Therefore, a centrifugal pump impeller cover plate processing device is needed to solve the problems of poor connectivity of the deburring operation and easy residue of tiny particles when deburring the centrifugal pump impeller cover plate using ultrasonic vibration in the prior art.

DETAILED DESCRIPTION

[0042] The present invention will be further described below in conjunction with the embodiments.

[0043] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure.

When the absolute position of the object being described changes, the relative position relationship may also change accordingly.

[0045] Embodiment 1:

[0046] See also Figure 1-9 The present invention provides a centrifugal pump impeller cover plate processing device, comprising an ultrasonic treatment box 1, and also comprising a spherical card seat 2, the spherical card seat 2 is fixed at the center of the bottom inner wall of the ultrasonic treatment box 1, a placement plate 3 is arranged above the spherical card seat 2, and a buckle mechanism 4 is arranged between the placement plate 3 and the spherical card seat 2;

[0047] A mounting frame 5 is fixed to the top surface of the end of the ultrasonic treatment box 1. An electric push rod 6 is fixed to the bottom surface of the top of the mounting frame 5. A lifting mechanism 7 is provided between the electric push rod 6 and the placement plate 3. A rotation mechanism 8 cooperating with the lifting mechanism 7 is provided below the placement plate 3.

[0048] It should be noted that, through the cooperation of the electric push rod 6 and the lifting mechanism 7, the placement plate 3 can be lifted up and down in the ultrasonic treatment box 1. When the centrifugal pump impeller cover plate is subjected to ultrasonic deburring, the placement plate 3 is first lifted by the electric push rod 6 and the lifting mechanism 7, so that the height of the placement plate 3 is higher than the top surface height of the ultrasonic treatment box 1, and then multiple centrifugal pump impeller cover plates are placed in the card slots on the placement plate 3 in turn, thereby completing the positioning and placement of multiple centrifugal pump impeller cover plates.

[0049] The placement plate 3 on which the centrifugal pump impeller cover plate is placed is moved downward by the electric push rod 6 and the lifting mechanism 7 until the bottom of the placement plate 3 is buckled with the spherical clamping seat 2 by the buckling mechanism 4. At this time, a plurality of centrifugal pump impeller cover plates are submerged below the liquid surface inside the ultrasonic treatment box 1, and the preparation work for ultrasonic deburring of the centrifugal pump impeller cover plates is completed;

[0050] By starting the ultrasonic generating device in the ultrasonic treatment box 1, the ultrasonic vibration deburring treatment is performed on the centrifugal pump impeller cover plate below the liquid surface through the vibration energy generated by the ultrasonic wave, and at the same time, the electric push rod 6 is pressed down again. Since the snap-fit ​​mechanism 4 is snap-fitted and positioned with the spherical holder 2, the placement plate 3 does not cover the ultrasonic height position at this time. At this time, the lifting mechanism 7 rebounds in the reverse direction, and the supply and rotation mechanism 8 moves synchronously, so that the placement plate 3 is rotated in the ultrasonic treatment box 1, thereby completing the rotary ultrasonic vibration deburring treatment of multiple centrifugal pump impeller cover plates. The electric push rod 6 drives the lifting mechanism 7 to reciprocate, so that the placement plate 3 and the centrifugal pump impeller cover plate located above the placement plate 3 can be reciprocated, thereby effectively reducing the possibility of residual tiny particles after the ultrasonic vibration deburring treatment;

[0051] When the ultrasonic vibration deburring treatment of the centrifugal pump impeller cover is completed, the electric push rod 6 drives the lifting mechanism 7 to move upward until the buckle mechanism 4 is separated from the spherical seat 2. At this time, the placement plate 3 and the centrifugal pump impeller cover plate located above the placement plate 3 are lifted up from the liquid in the ultrasonic treatment box 1 through the connection action of the lifting mechanism 7, and then the centrifugal pump impeller cover plate is taken out from the placement plate 3 and transferred to the subsequent flushing device for flushing treatment;

[0052] Partition plates 9, two of which are symmetrically fixed to the bottom inner wall of the ultrasonic treatment box 1, and a compression mechanism 10 cooperating with the supply and rotation mechanism 8 is arranged inside the partition plates 9;

[0053] It should be noted that the compression mechanism 10 moves synchronously with the supply and rotation mechanism 8, so that the partition 9 and the liquid in the ultrasonic treatment box 1 are subjected to reciprocating compression treatment, thereby compressing the liquid under the placement plate 3, thereby further improving the flow performance of the liquid in the ultrasonic treatment box 1, further avoiding the possibility of tiny particles remaining on the impeller cover plate of the centrifugal pump, and effectively reducing the difficulty of subsequent flushing treatment.

[0054] Further Figure 2 , Figure 4 , Figure 7 and Fig. 9 As shown, it is worth to explain in detail that the buckle mechanism 4 includes a docking column 41, which is detachably arranged on the inner wall of the ball-shaped card holder 2, and a spherical fixing column 42 is fixed on the top surface of the docking column 41;

[0055] The spherical collar 43 is fixedly embedded in the inner wall of the center of the placement plate 3, and the spherical collar 43 is rotatably sleeved on the outer surface of the spherical fixing column 42. The outer periphery of the spherical holder 2 is provided with a balancing piece 44 that matches the placement plate 3;

[0056] It should be noted that, by providing the balancing member 44 , the spherical collar 43 can be stably sleeved on the outer surface of the spherical fixing column 42 , thereby improving the stability of the placement plate 3 ;

[0057] It should be noted that, through the downward driving of the electric push rod 6 and the connection of the lifting mechanism 7, the docking column 41 below the placement plate 3 is elastically squeezed and buckled with the spherical socket 2, so that the placement plate 3 and the centrifugal pump impeller cover plate located above the placement plate 3 are immersed below the liquid level in the ultrasonic treatment box 1, thereby completing the buckling installation of the placement plate 3, and at the same time, the balance member 44 is stably located in the ultrasonic treatment box 1;

[0058] When the impeller cover plate of a centrifugal pump is subjected to ultrasonic vibration deburring treatment, the lifting mechanism 7 is driven by the electric push rod 6 to move downward, and then reset upward, thereby forming a downward and upward reciprocating motion of the lifting mechanism 7. At this time, the balancing member 44 moves synchronously with the supply and rotation mechanism 8, thereby ensuring the balance stability of the placement plate 3 when it is rotated by the supply and rotation mechanism 8.

[0059] Further Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 8 As shown, it is worth to explain in detail that the lifting mechanism 7 includes a T-shaped rod 71, the bottom end of the T-shaped rod 71 is rotatably connected to the top end of the spherical fixed column 42, and a fixed sleeve 72 is slidably sleeved on the top outer surface of the T-shaped rod 71, and the fixed sleeve 72 is detachably connected to the output end of the electric push rod 6;

[0060] The rotating block 73 is arranged inside the fixed sleeve 72 and the top surface of the rotating block 73 is arranged to fit the output end of the electric push rod 6. The opposite surface of the T-shaped rod 71 and the rotating block 73 is fixed with a pressing spring 74;

[0061] It should be noted that, through the elastic force of the pressing spring 74, the top end of the T-shaped rod 71 is located at the bottom of the fixed sleeve 72. At this time, when the electric push rod 6 drives the fixed sleeve 72, the T-shaped rod 71 and the placement plate 3 to move downward, the docking column 41 and the ball-shaped clamping seat 2 are elastically squeezed and buckled, so that the placement plate 3 can be buckled and installed inside the ultrasonic treatment box 1.

[0062] When the electric push rod 6 is driven to move downward again, the height of the placement plate 3 does not change through the snap-fitting action of the docking column 41 and the spherical socket 2, and the T-bar 71 is reversely compressed against the spring 74, thereby forming a fixed sleeve 72 that is driven by the electric push rod 6 to change its height above the ultrasonic treatment box 1.

[0063] Further Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 7 and Fig. 9 As shown, it is worth specifically explaining that the supply and rotation mechanism 8 includes an L-shaped rack rod 81, two L-shaped rack rods 81 are provided and both slide through the side wall of the ultrasonic treatment box 1, and the outer surface of the docking column 41 is tightly sleeved with a rotating gear 82, and the two L-shaped rack rods 81 are meshedly connected with the rotating gear 82, and the outer surface of the L-shaped rack rod 81 is provided with a tension spring 83 fixed to the L-shaped rack rod 81 and the outer surface of the ultrasonic treatment box 1;

[0064] A pressing sleeve rod 84 is tightly sleeved on the outer surface of the fixed sleeve 72. L-shaped rods 85 are fixed at both ends of the pressing sleeve rod 84. A pressing block 86 fixed to the L-shaped rod 85 is provided on the outer surface of the ultrasonic treatment box 1. The pressing block 86 is arranged to fit the outer surface of the end of the L-shaped rack rod 81 in an inclined manner.

[0065] The inner walls of both end surfaces of the ultrasonic treatment box 1 are fixed with mounting plates 11, and the opposite surfaces of the two mounting plates 11 are fixed with two upper and lower limit rods 12, and the L-shaped rack rod 81 is slidably arranged on the opposite surfaces of the two limit rods 12 at the same end;

[0066] It should be noted that the mounting plate 11 is provided with an ultrasonic generator and corresponding electrical components for generating ultrasonic waves in the ultrasonic treatment box 1, which are conventional settings in the art and will not be described in detail here. In addition, the setting of the limit rod 12 can further improve the movement stability of the L-shaped rack rod 81;

[0067] It should be noted that after the placement plate 3 is fastened and positioned by the fastening mechanism 4, the fixed sleeve 72 moves downward again with the electric push rod 6, and at the same time drives the pressing sleeve rod 84, the L-shaped rod 85 and the pressing block 86 to perform synchronous downward pressing. At this time, the pressing block 86 and the inclined surface of the end of the L-shaped rack rod 81 are squeezed, so that the L-shaped rack rods 81 at both ends move toward the outside of the ultrasonic treatment box 1 respectively, and at the same time drive the tension spring 83 to perform stretching. Through the meshing transmission of the L-shaped rack rod 81 and the rotating gear 82, and through the rotation limiting effect of the docking column 41 and the ball-type holder 2, the docking column 41, the balancing member 44, the spherical fixing column 42, the spherical collar 43 and the placement plate 3 are all rotated synchronously, that is, the rotary ultrasonic vibration deburring of the centrifugal pump impeller cover plate on the placement plate 3 is completed;

[0068] After the electric push rod 6 drives the fixed sleeve 72 to move down again, and then drives the fixed sleeve 72 to move up and reset, the pressing block 86 can be driven to reset. At this time, the elastic force of the tension spring 83 causes the L-shaped rack rod 81 to reset, and the meshing transmission of the L-shaped rack rod 81 and the rotating gear 82 can cause the placement plate 3 to rotate and reset, so that when the electric push rod 6 drives the fixed sleeve 72 to move down and rise reciprocatingly, the placement plate 3 can be reciprocated in the ultrasonic treatment box 1, completing the reciprocating rotation ultrasonic vibration deburring treatment of the impeller cover plate of the centrifugal pump;

[0069] It should be noted that a connecting protrusion for connecting the tension spring 83 is provided at the corner of the L-shaped rack rod 81, and the contact portion between the connecting protrusion and the pressing block 86 is arranged in an inclined surface.

[0070] Further Figure 2 , Figure 3 , Figure 6 and Fig. 9 As shown, it is worth to explain in detail that the compression mechanism 10 includes a compression plate 101, two compression plates 101 are provided and are respectively arranged on the top opposite surfaces of the partition plate 9 and the ultrasonic treatment box 1, and a pressing rod 102 is fixed between the compression plate 101 and the adjacent L-shaped rod 85;

[0071] A liquid inlet channel 103, which is opened on the top outer surface of the partition plate 9 and is located below the compression plate 101. A plurality of evenly distributed through holes 104 are opened on the bottom top surface of the partition plate 9;

[0072] It should be noted that, through the setting of the liquid inlet channel 103 and the through hole 104, the liquid in the space formed by the partition 9 and the ultrasonic treatment box 1 is filled. When the fixed sleeve 72 moves downward again with the electric push rod 6, the compression plate 101 is pressed down with the L-shaped rod 85 through the connection of the pressing plate until the compression plate 101 reaches the bottom of the liquid inlet channel 103. At this time, the compression plate 101 compresses the liquid in the partition 9 and the ultrasonic treatment box 1, and sprays it through the through hole 104, thereby forming an oblique upward spray of the liquid under the placement plate 3, further improving the liquid flow in the ultrasonic treatment box 1, and cooperating with the reciprocating rotation of the placement plate 3 in the ultrasonic treatment box 1, thereby further avoiding the possibility of tiny particles remaining inside the impeller cover of the centrifugal pump.

[0073] Further Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, it is worth to explain in detail that the outer surfaces of both sides of the ultrasonic treatment box 1 are fixed with receiving plates 13, and the outer end surface of the receiving plate 13 is arranged to fit with the outer surface of one end of the pressing block 86;

[0074] It should be noted that the receiving plate 13 can be used for the initial placement of the centrifugal pump impeller cover plate and temporary storage after deburring, and can also improve the stability of the pressing block 86 moving up and down with the L-shaped rod 85.

[0075] This embodiment has the following working process: when burring is processed on multiple centrifugal pump impeller cover plates, firstly, the placement plate 3 is moved to the top of the ultrasonic treatment box 1 through the connection between the electric push rod 6 and the lifting mechanism 7, and then the centrifugal pump impeller cover plates are placed and installed in sequence, completing the positioning and installation work of multiple centrifugal pump impeller cover plates;

[0076] Through the downward driving of the electric push rod 6 and the connection of the lifting mechanism 7, until the docking column 41 in the buckling mechanism 4 and the ball-shaped clamping seat 2 are elastically squeezed and buckled, the placement plate 3 is fully immersed below the liquid surface of the ultrasonic treatment box 1;

[0077] By the reciprocating drive of the electric push rod 6 moving downward again and ascending, the placement plate 3 can be made to rotate synchronously with the rotation mechanism 8, so that the placement plate 3 and the centrifugal pump impeller cover plate located on the placement plate 3 can be reciprocated. Compared with the centrifugal pump impeller cover plate being placed in the ultrasonic treatment box 1 for ultrasonic vibration deburring, the possibility of tiny particles remaining inside the centrifugal pump impeller cover plate is greatly reduced, and the difficulty of subsequent flushing treatment is greatly reduced;

[0078] After the centrifugal pump impeller cover plate is fully deburred, the electric push rod 6 is driven upward and the lifting mechanism 7 is connected until the docking column 41 in the snap-fit ​​mechanism 4 under the placement plate 3 is separated from the spherical seat 2, thereby forming an upward removal and unloading process of the centrifugal pump impeller cover plate. Subsequently, the centrifugal pump impeller cover plate is taken out of the placement plate 3 in turn and transferred to the subsequent flushing device, thereby completing the ultrasonic deburring process of the centrifugal pump impeller cover plate.

[0079] Embodiment 2:

[0080] Based on the first embodiment, Figure 3 , Figure 7 and Fig. 9 As shown, it is worth to explain in detail that the balance member 44 includes a fixed sleeve rod 441, the fixed sleeve rod 441 is fixed to the bottom outer surface of the docking column 41, and a balance rod 442 is slidably penetrated through the top surface of the end of the fixed sleeve rod 441, and the top end of the balance rod 442 is hingedly arranged with the bottom surface of the placement plate 3;

[0081] A sealing sleeve 443, which is arranged on the periphery of the balancing rod 442 and fixed to the bottom surface of the end of the fixed sleeve 441. A sealing ring 444 is arranged inside the sealing sleeve 443 and is tightly sleeved on the outer surface of the balancing rod 442. A balancing spring 445 is arranged on the outer surface of the balancing rod 442 and is fixed to the opposite surfaces of the sealing ring 444 and the fixed sleeve 441.

[0082] A fixed track ring 446, the fixed track ring 446 is fixed to the bottom inner wall of the ultrasonic treatment box 1, the bottom end of the balance rod 442 extends to the inside of the fixed track ring 446, and the track inner wall of the fixed track ring 446 is provided with a plurality of protrusions 447 distributed at equal angles;

[0083] It should be noted that when the docking column 41 rotates, the spherical fixed column 42, the fixed sleeve rod 441 and the balance rod 442 rotate synchronously. When the bottom end of the balance rod 442 contacts the protrusion 447, the balance rod 442 moves upward in the fixed sleeve rod 441, so that the placement plate 3 is deflected on the surface of the spherical fixed column 42 through the spherical collar 43, that is, the centrifugal pump impeller cover plate is subjected to reciprocating deflection and rotation treatment in the ultrasonic treatment box 1, which reduces the possibility of tiny particles remaining inside the centrifugal pump impeller cover plate to a certain extent.

[0084] In summary, in combination with the two embodiments, it can be known that: through the driving of the electric push rod 6 and the mutual cooperation between the lifting mechanism 7, the buckling mechanism 4 and the supply and rotation mechanism 8, the centrifugal pump impeller cover plate can be placed and installed in sequence, the placement plate 3 can be immersed in the liquid surface and buckled and positioned, the reciprocating ultrasonic vibration deburring and the upward lifting and material collection can be carried out in sequence, so as to realize the semi-automatic ultrasonic deburring treatment of the centrifugal pump impeller cover plate, which greatly improves the connection of the material discharge, ultrasonic vibration deburring and material collection operations of the centrifugal pump impeller cover plate. At the same time, the centrifugal pump impeller cover plate is subjected to reciprocating rotary ultrasonic vibration deburring treatment. Compared with the centrifugal pump impeller cover plate being placed in the ultrasonic treatment box 1 for ultrasonic vibration deburring treatment, it greatly reduces the possibility of tiny particles remaining inside the centrifugal pump impeller cover plate, and greatly reduces the difficulty of subsequent flushing treatment;

[0085] The compression mechanism 10 is arranged to move synchronously with the supply and rotation mechanism 8, so as to form an oblique upward spray of the liquid below the placement plate 3, further improving the liquid flow in the ultrasonic treatment box 1, and cooperating with the reciprocating rotation of the placement plate 3 in the ultrasonic treatment box 1, thereby further avoiding the possibility of small particles remaining inside the centrifugal pump impeller cover plate;

[0086] The setting of the balancing member 44 can not only ensure the stability of the placement plate 3 during the reciprocating rotation treatment, but also make the placement plate 3 deflect on the surface of the spherical fixing column 42 through the spherical collar 43 through the intermittent contact between the balancing rod 442 and the protrusion 447, that is, the centrifugal pump impeller cover plate performs a reciprocating deflection rotation treatment in the ultrasonic treatment box 1, thereby reducing the possibility of tiny particles remaining inside the centrifugal pump impeller cover plate to a certain extent.

[0087] The electric push rod 6 can be purchased from the market and equipped with a separate power supply, which is a mature technology in this field and has been fully disclosed, so it will not be repeated in the specification.
