Description

Technical Field

[0001] The present invention relates to the technical field of pump body cutting, and particularly to a cutting device for the production of a metal pump body of a twin-screw pump. Background Art

[0002] The cutting device used for the production of the metal pump body of a twin-screw pump is mainly applied after the casting of the metal pump body, and can accurately remove redundant parts such as gate, riser and flash on the pump body, which is a key production equipment to ensure the dimensional accuracy and surface quality of the pump body and improve the product performance.

[0003] However, there are still some problems in the existing pump body production cutting devices: First, in the existing pump body production cutting devices, there are many drawbacks in the operation of clamping the pump body. The traditional clamping method often relies on manual operation for placement and locking. This process not only consumes a large amount of labor and time costs, but also has high requirements for the skills of operators. Even if an additional driving source is used to achieve clamping, although the labor input is reduced to a certain extent, it brings a significant increase in equipment costs, which undoubtedly increases the total production cost of the enterprise and reduces the market competitiveness of the product.

[0004] More importantly, after the casting of the metal pump body of a twin-screw pump, there are inevitably raised impurities such as burrs and risers on its surface. During the placement process of the pump body, these protrusions may affect the fit between the pump body and the clamping device, resulting in a deviation between the actual placement position of the pump body and the expected coordinates. And during the clamping process, due to the obstruction of these protrusions, it is difficult for the clamping device to accurately position the pump body, further exacerbating the inaccuracy of the pump body coordinates.

[0005] Once the position of the pump body is inaccurate, when the cutting device performs the cutting task, it cannot operate according to the preset cutting path, which may lead to over-cutting, causing some useful materials of the pump body to be mistakenly cut off. This not only causes waste of materials, but also may affect the overall structural strength and dimensional accuracy of the pump body.

[0006] Second, during the cutting process of the pump body, the generation of debris is inevitable. However, the existing cutting devices have obvious deficiencies in dealing with debris. When the debris scatters on the ground, it is relatively easy to clean it with conventional cleaning tools. For example, using equipment such as brooms and vacuum cleaners can clean the debris on the ground. However, it is extremely difficult to clean the debris on the fixture of the cutting device.

[0007] As a key component for fixing the pump body, the fixture often has a relatively complex structure, with many gaps, grooves and other parts that are not easy to clean. The chips generated by cutting are easily stuck in these parts and are difficult to remove by simple means. Over time, these chips will have an adverse impact on the performance and accuracy of the fixture. On the one hand, the accumulation of chips may affect the clamping accuracy of the fixture for the pump body, because the chips may occupy a certain space, resulting in the fixture being unable to closely fit the surface of the pump body, so that the pump body shakes during the cutting process, further affecting the cutting quality. On the other hand, some metal chips may rust in a humid environment, which will not only damage the surface of the fixture, but also release rust particles, pollute the surface of the pump body, and reduce the surface quality of the product.

[0008] For this reason, the present invention proposes a cutting device for the production of the metal pump body of a double-screw pump. Summary of the Invention

[0009] The purpose of the present invention is to provide a cutting device for the production of the metal pump body of a double-screw pump to solve the problems raised in the above background technology.

[0010] To achieve the above purpose, the present invention provides the following technical solution: A cutting device for the production of the metal pump body of a double-screw pump, including a cutting unit and a fixture module. An adaptive clamping component is arranged above the fixture module. The adaptive clamping component includes a number of telescopic rods one fixedly connected to the top of the fixture module. The telescopic end of the telescopic rod one is fixedly connected with a driving block. The top of the fixture module is symmetrically and slidably connected with a cooperating block. Active bars are fixedly connected to the side walls of the driving block. Driven grooves are formed in the sides of the cooperating block close to the driving block. When the driving block is pushed down by the pump body, the driving block can drive the cooperating block to move closer to the middle of the driving block through the inclined surface cooperation of the active bar and the driven groove, so as to clamp the pump body.

[0011] Preferably, a number of telescopic rods two are fixedly connected to the tops of the cooperating blocks.

[0012] Preferably, a magnetic block is fixedly connected to the inside of each cooperating block. Protective shells are symmetrically and fixedly connected to the top of the fixture module. Block-shaped electromagnets are fixedly connected to the inside of the protective shells. The block-shaped electromagnets are connected to the device power supply. When the block-shaped electromagnet is energized, it generates a magnetic field with the opposite magnetism to the magnetic block. When the block-shaped electromagnet is de-energized, it has no magnetism.

[0013] Preferably, springs are symmetrically and fixedly connected to the inside of the driving block. A sliding plate is fixedly connected to the outer surface of the spring. A resisting block is fixedly connected to the top of the sliding plate.

[0014] Preferably, the side of the resisting block close to the middle of the driving block is arc-shaped.

[0015] Preferably, the sliding plate is slidably connected inside the active block, and an external displacement sensing module is installed on the side of the sliding plate away from the center of the active block.

[0016] Preferably, a protective shell is installed outside the cutting unit, the bottom of the clamping fixture module is installed on the inner surface of the protective shell, and a control box is installed on the inner surface of the protective shell.

[0017] Preferably, an adaptive cleaning assembly is arranged outside the clamping fixture module. The adaptive cleaning assembly includes air nozzles symmetrically installed on the top of the clamping fixture module. Hoses are fixedly connected to the bottoms of the air nozzles, and the sides of the hoses away from the air nozzles are all connected to an external negative pressure device.

[0018] Preferably, rotating seats are rotatably connected to the outer surfaces of the sliding plates, the air nozzles are rotatably connected to the outer surfaces of the clamping fixture module, sliding rods are rotatably connected to the outer surfaces of the air nozzles, the sliding rods are slidably connected inside the rotating seats, lead screws are symmetrically rotatably connected to the side walls of the control box, torsion springs are fixedly connected between the lead screws and the control box, and the hoses are wound around the outer surfaces of the lead screws.

[0019] Preferably, a sliding groove is formed on the outer surface of the clamping fixture module, and the side of the hose close to the sliding rod is fixedly connected inside the sliding groove.

[0020] Preferably, the block-shaped electromagnet is linked to the start-stop signal of the cutting unit. When the cutting unit starts, the block-shaped electromagnet is powered off, and when the cutting unit stops, the block-shaped electromagnet is powered on.

[0021] Preferably, the middle position between the two external displacement sensing modules is defined as the positioning origin of the pump body.

[0022] Preferably, when the cutting unit approaches one side of the air nozzle, the air nozzle on that side switches to the negative pressure suction mode, and the air nozzle on the opposite side switches to the blowing mode.

[0023] Preferably, an external manipulator is installed on the inner surface of the protective shell, and the external manipulator is used to clamp the pump body to the clamping fixture module.

[0024] Compared with the prior art, the beneficial effects of the present invention are: 1. When the pump body is pressed down, the active block can drive the matching blocks on both sides to move closer to the pump body and clamp it. This design uses the pump body's own gravity to achieve the self-locking function, abandoning the traditional clamping method that relies on manual operation for placement and locking, or the complex mode of using an additional drive source. The operation process becomes extremely simple, greatly saving manpower and time costs, and reducing the requirements for operator skills. At the same time, the telescopic rod 2 can be flexibly telescopically adjusted. When facing burrs, risers and other uneven places on the surface of the pump body, the telescopic rod 2 can adaptively change its length to ensure that the matching block is fully fitted with the surface of the pump body, achieving stable clamping and avoiding the problem of unstable clamping caused by the uneven surface of the pump body.

[0025] 2. When the cutting unit is closed, the block-shaped electromagnet is powered off, generating a magnetic field with an opposite magnetic property to that of the magnetic block. The two attract each other, so that the matching block can be easily separated from the pump body and the pump body is automatically unlocked. This function avoids the tedious process of unlocking the pump body by manual or additional operations in traditional devices, improves production efficiency and reduces labor intensity.

[0026] 3. When the pump body is pressed down to make the active block drop, the pump body contacts the resistance block, compresses the spring and drives the sliding plate to slide inside the active block. At this time, the external displacement sensing module will monitor the displacement in real time, and define the middle position between the two external displacement sensing modules as the positioning origin of the pump body. By analyzing and calculating the data of the two external displacement sensing modules, the center point position of the pump body can be accurately determined. This enables the cutting device to perform precise operations according to the preset cutting path when performing the cutting task, avoiding the problem of over-cutting or inadequate cutting due to inaccurate position of the pump body, and ensuring the dimensional accuracy and surface quality of the pump body.

[0027] 4. When the coordinates of the pump body change due to various factors, the sliding plate will be displaced accordingly. Since the outer surface of the sliding plate is rotatably connected to a rotating seat, the rotating seat is slidably connected to the sliding rod, and the sliding rod is rotatably connected to the air nozzle, the air nozzle can respond to the displacement change of the sliding plate in real time and change its own angle synchronously. In addition, based on the negative pressure suction and blowing functions of the air nozzles on both sides, during the cutting process, the air nozzle close to the cutting unit is switched to the negative pressure suction mode, and the strong suction force can quickly absorb the debris generated by the cutting to prevent it from splashing everywhere; the air nozzle on the opposite side is switched to the blowing mode, and the air flow can blow away the debris that may drift to the fixture module, thereby minimizing the possibility of debris falling on the fixture module.

[0028] 5. When the fixture module rotates or moves, the lead screw will rotate accordingly. Since the hose is wound around the outer surface of the lead screw and one side of the hose close to the sliding rod is fixedly connected inside the chute, the rotation of the lead screw will cause the hose to release or shorten its length. The presence of the torsion spring ensures that the lead screw can maintain a certain initial state when not subjected to external forces, making the length adjustment of the hose more stable and accurate. This design enables the hose to always closely follow during the movement of the fixture module, without problems such as pulling and entanglement, ensuring the normal operation of the nozzle and maintaining the stable operation of the entire cleaning system.

[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0034] It should be noted that the cutting unit 11 only provides the function of cutting the pump body, the fixture module 12 only provides the functions of displacement and placing the pump body, the external displacement sensing module only provides the function of detecting the displacement amount, the external manipulator only provides the function of loading and unloading the pump body, and the external negative pressure device only provides the functions of generating negative pressure and reverse blowing. The working principles and specific structures of the above structures are all prior arts. Therefore, due to the generality of the above structures, the specific principles will not be described in detail hereinafter.

[0035] Example 1, please refer to Figures 1 to 8 As shown, a cutting device for the production of a double-screw pump metal pump body includes a cutting unit 11 and a fixture module 12. An adaptive clamping component is arranged above the fixture module 12. The adaptive clamping component includes a plurality of first telescopic rods 21 fixedly connected to the top of the fixture module 12. The telescopic ends of the first telescopic rods 21 are fixedly connected with active blocks 22. The top of the fixture module 12 is symmetrically and slidably connected with cooperating blocks 23. Active strips 221 are fixedly connected to the side walls of the active blocks 22. Driven grooves 231 are formed on the sides of the cooperating blocks 23 close to the active blocks 22. When the active block 22 is pushed down by the pump body, the active block 22 can drive the cooperating blocks 23 to move closer to the middle of the active block 22 through the inclined surface cooperation of the active strips 221 and the driven grooves 231, so as to clamp the pump body.

[0036] It should be noted that a plurality of second telescopic rods 24 are fixedly connected to the tops of the cooperating blocks 23. A magnetic block 25 is fixedly connected to the inside of each cooperating block 23. Protective shells 26 are symmetrically and fixedly connected to the top of the fixture module 12. Block-shaped electromagnets 27 are fixedly connected to the inside of the protective shells 26. The block-shaped electromagnets 27 are connected to the device power supply. When the block-shaped electromagnet 27 is powered on, it generates a magnetic field opposite to the magnetic block 25. When the block-shaped electromagnet 27 is powered off, it has no magnetism. The active block 22 is symmetrically fixedly connected to the inside with a spring 28, the outer surface of the spring 28 is fixedly connected to a sliding plate 29, the top of the sliding plate 29 is fixedly connected to a resisting block 210, the side of the resisting block 210 close to the middle of the active block 22 is arc-shaped, the sliding plate 29 is slidably connected to the inside of the active block 22, and the side of the sliding plate 29 away from the center of the active block 22 is installed with an external displacement sensing module, and the cutting unit A protective shell 14 is installed on the outside of 11, and the bottom of the clamp module 12 is installed on the inner surface of the protective shell 14. The control box 13 is installed on the inner surface of the protective shell 14. The block electromagnet 27 is linked with the start and stop signals of the cutting unit 11. When the cutting unit 11 starts, the block electromagnet 27 is powered off, and when the cutting unit 11 stops, the block electromagnet 27 is powered on. The middle position between the two external displacement sensor modules is defined as the positioning origin of the pump body. An external manipulator is installed on the inner surface of the protective shell 14, and the external manipulator is used to clamp the pump body to the clamp module 12.

[0037] Specifically, after the cutting unit 11 is started, the entire cutting device begins to enter a working state.

[0038] At this time, the external manipulator installed on the inner surface of the protective shell 14 transports the pump body to the clamp module 12. At this time, the gravity of the pump body acts on the active block 22, so that the active block 22 squeezes the telescopic rod 21, and the telescopic rod 21 begins to compress, and the active block 22 then descends synchronously with the telescopic rod 21.

[0039] Since the active strip 221 on the side wall of the active block 22 and the driven groove 231 on the matching block 23 have an inclined surface, when the active block 22 descends, the inclined surface enables the matching block 23 to move closer to the pump body along the top of the clamp module 12, and the telescopic rod 24 on the top of the matching block 23 plays an important adaptive role in the process of approaching the pump body.

[0040] Since the surface of the pump body inevitably has burrs, risers and other raised impurities, the surface is not smooth, and the telescopic rod 24 will be compressed or stretched according to the shape of the pump body surface to ensure that the matching block 23 can fit tightly with the surface of the pump body to achieve stable clamping of the pump body. This self-locking clamping method that relies on the pump body's own gravity not only simplifies the operation process and saves manpower and time costs, but also reduces the skill requirements for operators. It has obvious advantages over traditional clamping methods.

[0041] When the pump body descends and is clamped, the bottom of the pump body will come into contact with the resistance block 210. The side of the resistance block 210 close to the middle of the active block 22 is arc-shaped, which can better contact with the surface of the pump body. After the resistance block 210 is subjected to force, it drives the sliding plate 29 to slide inside the active block 22 and compresses the spring 28 at the same time.

[0042] Due to the uneven surface of the pump body and the possible deviations during the clamping process of the external manipulator, it is often difficult for the pump body to be precisely centered in the fixture module 12. The deviation in the position of the pump body will cause different moving distances of the two side abutting blocks 210 when it abuts against them. The external displacement sensing module installed on the outer side of the sliding plate 29 away from the center of the driving block 22 can detect this displacement difference in real time. By accurately measuring the distance between the two external displacement sensing modules, the new center coordinates of the pump body can be accurately calculated.

[0043] After obtaining the new coordinates, the cutting unit 11 cuts the pump body, avoiding the problems of over-cutting or under-cutting caused by inaccurate pump body position, and ensuring the dimensional accuracy and surface quality of the pump body.

[0044] It should be noted that when the cutting of the pump body is completed, the cutting unit 11 is turned off. At this time, the block-shaped electromagnet 27 linked to the start-stop signal of the cutting unit 11 is energized, generating a magnetic field opposite to the magnetism of the magnet block 25. Under the action of the magnetic field force, the magnet block 25 drives the mating block 23 away from the driving block 22, and the distance between the mating block 23 and the pump body increases, thereby releasing the clamping of the pump body. This automatic unlocking function avoids the cumbersome process of manual or additional operations to unlock in traditional devices, improves production efficiency, and reduces labor intensity.

[0045] Subsequently, the external manipulator can take out the cut pump body again and place a new pump body to be cut, starting a new round of cutting operation.

[0046] Embodiment 2, on the basis of Embodiment 1, please refer to as Figures 9 to 11 shown, an adaptive cleaning component is provided outside the fixture module 12. The adaptive cleaning component includes air nozzles 33 symmetrically installed on the top of the fixture module 12. The bottoms of the air nozzles 33 are fixedly connected and communicated with hoses 35, and the other sides of the hoses 35 away from the air nozzles 33 are connected to an external negative pressure device.

[0047] It should be noted that rotating seats 32 are rotatably connected to the outer surfaces of the sliding plates 29, the air nozzles 33 are rotatably connected to the outer surfaces of the fixture module 12, sliding rods 34 are rotatably connected to the outer surfaces of the air nozzles 33, the sliding rods 34 are slidably connected inside the rotating seats 32, lead screws 36 are symmetrically rotatably connected to the side walls of the control box 13, torsion springs 37 are fixedly connected between the lead screws 36 and the control box 13, the hoses 35 are wound around the outer surfaces of the lead screws 36, and sliding grooves 31 are opened on the outer surfaces of the fixture module 12. The sides of the hoses 35 close to the sliding rods 34 are fixedly connected inside the sliding grooves 31. When the cutting unit 11 approaches a certain side air nozzle 33, that side air nozzle 33 switches to the negative pressure suction mode, and the opposite side air nozzle 33 switches to the blowing mode.

[0048] Specifically, in the first embodiment, the sliding plate 29 in the adaptive clamping assembly will be displaced as the pump body is lowered. Since the outer surface of the sliding plate 29 is rotatably connected to the rotating seat 32, the displacement of the sliding plate 29 will drive the movement of the rotating seat 32. The rotating seat 32 is also slidably connected to the sliding rod 34, and the sliding rod 34 is rotatably connected to the nozzle 33. In this way, the movement of the rotating seat 32 will change the angle of the nozzle 33 through the sliding rod 34, so as to realize the real-time response of the nozzle 33 to the change of the pump body position.

[0049] As the cutting unit 11 performs cutting operations on the pump body, a large amount of debris will be generated. When the cutting unit 11 approaches a certain side nozzle 33, the control box 13 receives the corresponding signal and controls the external negative pressure device to switch the nozzle 33 on that side to the negative pressure suction mode. The strong suction force can quickly suck away the debris generated by cutting, prevent the debris from splashing everywhere and falling on the fixture module 12. At the same time, the nozzle 33 on the opposite side is switched to the blowing mode, and the blown air flow blows away the debris that may drift towards the fixture module 12, keeping the fixture module 12 clean to the greatest extent.

[0050] When the fixture module 12 rotates or moves, since the hose 35 is wound around the outer surface of the lead screw 36 and its side close to the sliding rod 34 is fixed in the chute 31, the movement or rotation of the fixture module 12 will drive the rotation of the lead screw 36, and then release or shorten the length of the hose 35 through the rotation of the lead screw 36. The torsion spring 37 ensures that the lead screw 36 maintains a certain initial state when not subject to external forces, making the length adjustment of the hose 35 stable and accurate, avoiding problems such as pulling and winding, and ensuring the normal operation of the nozzle 33.

[0051] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "including", "comprising" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "including a..." does not exclude the existence of additional identical elements in the process, method, article or device including the said element.

[0052] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
