Description

Technical Field

[0001] The present invention relates to the technical field of intelligent manufacturing equipment industry, and specifically to a finishing molding machine for polishing an integrated pump body. Background Art

[0002] The integrated pump body, as the "heart component" of various fluid machinery such as centrifugal pumps, gear pumps, screw pumps, and plunger pumps, is the core carrier for achieving fluid suction, pressurization, and transportation. Its structure and performance directly determine the operating efficiency, energy consumption level, sealing reliability, and service life of the entire machine. This type of pump body is usually made of materials such as cast iron, cast steel, stainless steel, or high-strength alloys. After initial formation through casting (sand casting, investment casting) or forging processes, it needs to be precisely polished and finished to form its final working form. Its structural characteristics and processing requirements are significantly complex. Throughout the production life cycle of the pump body, polishing and finishing is the key link that determines its ultimate performance. By removing burrs, flash, and oxide scale left over from casting and forging, correcting surface errors, and reducing surface roughness, it can not only improve the structural integrity of the pump body, but also reduce fluid flow resistance, optimize sealing effects, and extend the service life of the equipment.

[0003] However, when the existing one-piece pump body finishing forming machine is used to grind the pump body, the clamping device is mostly a fixed structure, which can only adapt to pump bodies of specific shapes or sizes. For special-shaped pump bodies or pump bodies of different specifications, the clamps need to be replaced frequently, which is not only cumbersome, time-consuming and labor-intensive, but also causes accumulation of positioning errors due to fixture replacement, affecting the processing accuracy. At the same time, during the grinding process, the existing clamping device often causes slight displacement of the pump body due to vibration, which can easily cause equipment loss and unstable processing quality, making it difficult to meet the needs of modern flexible production for high efficiency, precision and multi-adaptability. Summary of the Invention

[0004] In order to solve the problem that the traditional clamping devices proposed in the background technology are mostly fixed structures and can only adapt to pump bodies of specific shapes or sizes, and for special-shaped pump bodies or pump bodies of different specifications, it is necessary to frequently replace the clamps, which is cumbersome and inefficient to operate, and is difficult to meet the needs of flexible production, the present invention provides an integrated pump body polishing finishing molding machine, which includes a machine body, a drive motor, a threaded rod, and a movable frame. The molding machine uses the machine body as a basic carrier and is powered by the drive motor to cooperate with the movable component, the limiting component and the fixed component to achieve clamping and polishing of pump bodies of different shapes and sizes. The movable component includes: a fixed frame, which is fixedly mounted on the top of the movable frame, a fixed plate is fixedly mounted on the inner side of the fixed frame, a movable block is slidably connected to the surface of the fixed plate, a fixed shaft 1 is fixedly mounted on the bottom of the movable block, a clamping plate is rotatably connected to the bottom of the fixed shaft 1, and a clamping shaft is rotatably connected to the surface of the clamping plate, a control motor is fixedly mounted on the top of the fixed frame, and a fixed rod is fixedly mounted on the surface of the output shaft of the control motor, one end of the movable rod is hinged to the bottom of the fixed rod, and the other end of the movable rod is hinged to the top of the movable block.

[0005] In order to solve the problem of limiting pump bodies of different shapes and sizes, this technical solution adopts the method of starting the driving motor, and its output shaft drives the threaded rod to rotate inside the body. Since the movable frame is threadedly connected to the threaded rod and slidably connected to the outer wall of the body, the rotational movement of the threaded rod is converted into a linear movement of the movable frame along the body, thereby driving the movable component on the top and the clamped pump body to adjust the position to adapt to the different workstation requirements of the grinding process. After the control motor is started, its output shaft drives the fixed rod to rotate, and the fixed rod pulls the moving block to slide along the surface of the fixed plate through the hinged movable rod to realize the position adjustment of the moving block. The fixed shaft at the bottom of the moving block is The connecting splint can be rotated around a fixed axis to adapt to the shape of the pump body; at the same time, the clamping axis on the surface of the splint can be further rotated, and through multi-directional angle adjustment, the splint can be closely fitted to the surface of the pump body to complete the preliminary clamping of pump bodies of different shapes and sizes. The splint has a triangular structure, and the triangle itself has geometric stability. When the splint is designed to be triangular, its contact point with the surface of the pump body can form a stable triangular support structure. The triangular splint can disperse the clamping force more evenly, reduce the shaking or displacement of the pump body due to uneven force during the grinding process, and is especially suitable for clamping irregular-shaped pump bodies to ensure stability during processing.

[0006] As a further improvement of the present technical solution, the limiting component includes: a moving bar, which is fixedly installed on the bottom of the moving block, a resistance plate is fixedly installed on the outside of the moving bar, a fixed shaft 2 is fixedly installed on the outside of the resistance plate, a resistance shaft is slidably connected inside the fixed shaft 2, the resistance shaft passes through the resistance plate, a fixed spring is fixedly installed on the outside of the resistance shaft, and the fixed spring is fixedly installed inside the fixed shaft 2.

[0007] On this basis, since the pump body is subjected to continuous friction and vibration during the grinding process, clamping it only by the splint of the movable component may cause slight displacement due to the smooth surface of the pump body, uneven force or vibration, affecting the processing accuracy and even posing a risk of the pump body falling off. Especially for pump bodies with special-shaped or curved structures, a single clamping force is difficult to completely offset the radial or axial forces during processing, and local loosening is prone to occur. In order to improve the limiting effect of the pump body and ensure that it always maintains a stable posture during the processing, the limiting component is strengthened and fixed by multiple elastic friction structures: the moving bar moves synchronously with the moving block. When the splint clamps the pump body, the friction plate is close to the side of the pump body. The friction shaft extends from the inside of the fixed shaft 2 under the elastic force of the fixed spring and tightly contacts the surface of the pump body. This elastic resistance can not only adapt to the subtle bumps on the pump body surface, absorb processing vibrations through the buffering effect of the fixed spring, but also provide a reverse force when the pump body has a tendency to slightly displace, and cooperate with the clamping force of the splint to form a double fixation of "clamping and resistance", effectively preventing the pump body from shifting or shaking during the grinding process, and ensuring the dimensional accuracy and surface quality of the fine processing.

[0008] As a further improvement of the present technical solution, the fixed assembly includes: a fixed block, which is fixedly mounted on the surface of the fixed frame, a connecting block fixedly mounted on the top of the fixed block, a movable shaft passing through the surface of the connecting block, a plug plate fixedly mounted on the surface of the movable shaft, an insertion strip fixedly mounted on the bottom of the plug plate, a tooth plate fixedly mounted on the top of the movable block, the insertion strip is plugged into the top of the tooth plate, a volute spring fixedly mounted on the surface of the movable shaft, and the volute spring fixedly mounted on the outer wall of the connecting block.

[0009] In another scheme, since the movable component completes the position adjustment and clamping action under the drive of the driving motor and the control motor, the continuous vibration generated during the grinding of the pump body may be transmitted to the movable block, resulting in slight looseness of the sliding connection between it and the fixed plate; at the same time, although the elastic interference structure of the limiting component can buffer the vibration, long-term force may cause the position of the movable block to gradually shift, thereby affecting the clamping and limiting effect of the splint and the interference shaft on the pump body, and ultimately resulting in a decrease in processing accuracy. In order to completely lock the position of the movable block and ensure the stability of the movable component and the limiting component, the fixed component is rigidly fixed through a mechanical locking structure: after the movable block is adjusted into place, the elastic force of the volute spring drives the movable shaft to rotate in the connecting block, so that the insertion strip at the bottom of the insertion plate is accurately inserted into the tooth groove of the tooth plate, and the meshing action of the teeth is used to limit the sliding of the movable block; if the position needs to be adjusted, the movable shaft can be manually rotated to compress the volute spring to disengage the insertion strip from the tooth plate. After the adjustment is completed, the movable shaft can be released to automatically reset and lock. This design not only prevents the moving block from being displaced due to vibration or force, but also ensures the convenience of the adjustment process. It provides a reliable position reference for the clamping accuracy of the movable component and the interference effect of the limiting component, further improving the stability and accuracy of the equipment processing.

[0010] As a further improvement of the present technical solution, the cross-section of the splint is triangular, there are three clamping shafts, and the three clamping shafts are arranged in a circular array with the center point of the splint as the center of the circle, there are two groups of limiting components and fixing components, and the two groups of limiting components and fixing components are symmetrically arranged with the center line of the fixing frame as the axis of symmetry, a sliding groove is provided on the surface of the fixing plate, the cross-section of the movable bar is L-shaped, and the cross-section of the inserting bar is triangular.

[0011] In order to improve the equipment's clamping stability, adaptability, and structural rigidity for the pump body, the above design achieves precise processing through multi-dimensional optimization; As a further improvement of this technical solution, the triangular cross-section of the clamping plate is combined with three circular array clamping shafts to form a stable three-point clamping structure. The stability of the triangle is used to disperse the clamping force. At the same time, the uniform distribution of the clamping shafts can adapt to the curved or special-shaped surface of the pump body, ensuring that the contact points are balanced and avoiding deformation of the pump body caused by excessive local stress; two sets of symmetrically arranged limiting components and fixing components are symmetrically distributed along the center line of the fixing frame, which can apply symmetrical restraining forces from both sides of the pump body to offset the lateral force generated during processing, prevent the pump body from deflecting due to unilateral force, and enhance the overall limiting effect; the sliding groove on the surface of the fixing plate is The moving block provides precise guidance to ensure its stable sliding trajectory and prevent the moving block from deviating and affecting the clamping accuracy; the moving bar with an L-shaped cross-section has both connection and support functions, and the two vertical side surfaces firmly connect the moving block and the contact plate, thereby improving the structural rigidity of the limiting component when it moves synchronously with the moving block and preventing the loosening of components caused by vibration; when the inserting bar with a triangular cross-section is connected to the tooth plate, the self-locking characteristics of the triangle are used to enhance the occlusal stability, preventing the inserting bar from detaching from the tooth plate due to processing vibration, ensuring the locking effect of the fixed component on the moving block, and ultimately achieving stable clamping and precise positioning of the pump body during high-precision grinding.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. This one-piece pump body polishing finishing molding machine achieves improved adaptability and processing efficiency: through the multi-directional adjustment structure of the movable component, combined with the design of the triangular clamping plate and the circumferential array clamping shaft, the clamping plate can rotate around the fixed axis to adapt to the shape of the pump body; the triangular clamping plate can more evenly disperse the clamping force, reduce the shaking or displacement of the pump body caused by uneven force during the polishing process, and achieve adaptive clamping of pump bodies of different shapes and sizes. There is no need to frequently change the clamp, which significantly reduces the auxiliary operation time and improves the dimensional accuracy and surface quality of the processing.

[0013] 2. In this one-piece pump body polishing finishing molding machine, enhanced clamping stability and processing accuracy are achieved: the elastic resistance of the limiting component and the clamping force of the movable component form a double fixation, and the rigid locking of the fixed component effectively offsets the displacement caused by the polishing vibration, ensures the position accuracy of the pump body during the processing, and improves the surface polishing quality.

[0014] 3. In this one-piece pump body polishing finishing molding machine, the service life of the equipment is extended and the operational safety is achieved: rigid fixation is achieved through a mechanical locking structure: after the moving block is adjusted into place, the elastic force of the scroll spring drives the movable shaft to rotate in the connecting block, so that the insert strip at the bottom of the insert plate is accurately inserted into the tooth groove of the tooth plate, ensuring the convenience of the adjustment process, providing a reliable position reference for the clamping accuracy of the movable component and the interference effect of the limiting component, and further improving the stability and accuracy of the equipment processing.

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0018] Existing pump body grinding equipment has problems such as poor adaptability of the clamping device, easy displacement during processing, cumbersome operation and rapid equipment wear and tear.

[0019] For this purpose, the present invention provides an integrated pump body polishing finishing molding machine, see Figure 1-5 As shown, it includes a body 1, a driving motor 2 is installed on the outside of the body 1, a threaded rod 3 is installed on the output shaft surface of the driving motor 2, the threaded rod 3 is rotatably connected to the inner side of the body 1, and a movable frame 4 is threadedly connected to the surface of the threaded rod 3, and the movable frame 4 is slidably connected to the outer wall of the body 1; a movable component 5 is provided on the top of the movable frame 4, a limiting component 6 is provided in the movable component 5, and a fixing component 7 is provided on the limiting component 6.

[0020] For details, see Figure 1-Figure 2 As shown, in order to adjust the clamping position of different pump bodies, the driving motor 2 is started, and its output shaft drives the threaded rod 3 to rotate inside the body 1. Since the movable frame 4 is threadedly connected to the threaded rod 3 and is slidingly connected to the outer wall of the body 1, the rotational movement of the threaded rod 3 is converted into a linear movement of the movable frame 4 along the body 1, thereby driving the movable component 5 on the top and the clamped pump body to adjust the position to adapt to the different workstation requirements of the grinding process.

[0021] When the control motor 58 is activated, its output shaft rotates the fixed rod 59. The fixed rod 59, through the hinged movable rod 510, pulls the movable block 53 along the slide groove 520 on the surface of the fixed plate 52, achieving position adjustment of the movable block 53. The fixed axis 1 54 at the bottom of the movable block 53 connects to the clamping plate 55. The clamping plate 55 can rotate around the fixed axis 1 54 to adapt to the shape of the pump body. Simultaneously, the clamping axis 57 on the surface of the clamping plate 55 can further rotate. Through multi-directional angle adjustment, the clamping plate 55 is tightly attached to the pump body surface, completing the initial clamping of pump bodies of various shapes and sizes.

[0022] For further information, see Figure 6-Figure 8As shown, to enhance clamping stability, the limiting assembly 6 moves synchronously with the moving block 53. When the clamping plate 55 clamps the pump body, the contact plate 62 abuts against the side of the pump body. Under the elastic force of the fixing spring 65, the contact shaft 64 extends from the fixed shaft 63 and tightly contacts the surface of the pump body. This elastic contact can adapt to the subtle irregularities on the pump body surface. The buffering effect of the fixing spring 65 absorbs processing vibrations, and the clamping force of the clamping plate 55 forms a double clamping and contact fixation to prevent the pump body from deflecting.

[0023] The cross-section of the clamping plate 55 is triangular, a shape inherently geometrically stable. The contact points with the pump body surface form a stable triangular support structure, distributing the clamping force more evenly and reducing any shaking or displacement of the pump body caused by uneven force during the polishing process. This makes it particularly suitable for clamping irregularly shaped pump bodies. Three clamping shafts 57 are arranged in a circular array centered around the center of the clamping plate 55, adapting to curved or irregularly shaped pump surfaces and ensuring balanced force at the contact points.

[0024] For further information, see Figure 9 As shown, to lock the position of the movable block 53, the fixing assembly 7 uses the elastic force of the spiral spring 77 to drive the movable shaft 73 to rotate within the connecting block 72, so that the insertion bar 75 at the bottom of the insertion plate 74 is precisely inserted into the tooth groove of the tooth plate 76. The meshing action of the teeth restricts the sliding of the movable block 53. If the position needs to be adjusted, the movable shaft 73 can be manually rotated to compress the spiral spring 77, so that the insertion bar 75 disengages the tooth plate 76. After the adjustment is completed, the movable shaft 73 can be released to automatically reset the lock.

[0025] It should be noted that both the limiting assembly 6 and the fixing assembly 7 are provided in two groups, symmetrically arranged about the centerline of the fixing frame 51. This allows for symmetrical restraining forces to be applied from both sides of the pump body, counteracting the lateral forces generated during machining. The movable bar 61 has an L-shaped cross-section, providing both connection and support functions. Its two vertical side surfaces securely connect the movable block 53 and the contact plate 62, respectively, enhancing structural rigidity. The insertion bar 75 has a triangular cross-section, leveraging its self-locking properties to enhance the stability of its engagement with the toothed plate 76 and prevent it from becoming detached due to machining vibrations.

[0026] In summary, the present invention effectively solves the problems of poor adaptability, complicated operation, low processing precision and rapid equipment wear of traditional pump body grinding equipment through the coordinated work of the movable component 5, the limiting component 6 and the fixed component 7.

[0027] In summary, the present invention effectively solves the problem that most existing clamping devices are fixed structures and can only adapt to pump bodies of specific shapes or sizes. For special-shaped pump bodies or pump bodies of different specifications, the clamps need to be replaced frequently, which is cumbersome and inefficient to operate and difficult to meet the needs of flexible production.

[0028] Working principle: Place the pump body to be polished between the splints 55, start the control motor 58, and drive the movable block 53 to slide through the fixed rod 59 and the movable rod 510, so that the splint 55 and the clamping shaft 57 fit the surface of the pump body to complete the initial clamping; at the same time, the abutment shaft 64 of the limiting component 6 abuts the pump body under the action of the fixed spring 65, forming a double fixation. Start the drive motor 2, drive the movable frame 4 to move through the threaded rod 3, adjust the relative position of the pump body and the polishing head, and start the polishing device for processing. During the processing, the insert 75 of the fixed component 7 is inserted into the tooth plate 76 to lock the position of the movable block 53 to prevent vibration displacement. After the processing is completed, manually rotate the movable shaft 73 to disengage the insert 75 from the tooth plate 76, and control the motor 58 to reverse and drive the splint 55 to reset.
