Abstract
Description
Technical Field
[0001] This utility model relates to the field of processing, and more specifically, to a ball valve core clamping processing equipment. Background Technology
[0002] Ball valves, as key fluid control components, are widely used in petrochemical, power energy, and water conservancy projects. The machining quality of their valve cores directly affects the valve's sealing performance and service life. During the machining of ball valve cores, clamping stability and machining accuracy are the core challenges. Because ball valve cores are typically spherical or hemispherical, and their surfaces require high-precision machining (such as grinding and drilling), traditional clamping methods often suffer from uneven clamping force, poor adaptability, and are prone to workpiece deformation or displacement, thus affecting the accuracy of the machined surface. Furthermore, metal shavings and coolant splashes generated during machining not only pollute the environment but may also penetrate the clamping mechanism, causing equipment wear or decreased accuracy.
[0003] Chinese Patent (Announcement No.: CN204248709U) discloses a ball valve core clamping device, which includes a mounting plate, a support base, and a clamping plate. The support base is connected to the mounting plate and is hollow. The inner surface of the hollow part mates with the outer surface of the ball valve core. The clamping plate can be inserted into the medium channel of the valve core, and both ends extend out of the medium channel. The clamping plate has clamping holes at both ends. The mounting plate has threaded holes at positions opposite to the clamping holes. Screws pass through the threaded holes and clamping holes at both ends of the clamping plate and are clamped by nuts.
[0004] However, the aforementioned traditional equipment still has the following drawbacks: 1. The clamping force relies on manual adjustment, and the tightening force of the screw depends entirely on the operator's experience, which can easily lead to uneven clamping force. 2. It has limited adaptability, as the clamping relies on the through structure of the valve core's medium channel, and cannot be adapted to valve cores without through holes or with irregular shapes (such as the ball core of an eccentric hemispherical valve). Utility Model Content
[0005] Based on this, in order to solve the problems of traditional equipment relying on manual adjustment of clamping force and limited adaptability, this utility model provides a ball valve core clamping processing equipment, the specific technical solution of which is as follows:

[0007] Machine tool;
[0008] A punching device, which is mounted on the machine base;
[0009] A splash-proof device includes a base and a splash-proof cover. The base is mounted on the machine platform, and the splash-proof cover is hinged to the base. A first space is formed between the splash-proof cover and the base. The splash-proof cover has an opening for the processing end of the punching device to pass through.

[0011] The aforementioned ball valve core clamping processing equipment forms a closed first space through a splash guard hinged to the base, completely enclosing the clamping device and valve core, effectively isolating them from the external environment. An opening at the top of the splash guard allows the punching device's processing end to enter while preventing debris from scattering. Three or more clamping units are distributed inside the outer shell component, their ends passing through guide grooves to form an enveloping clamp on the valve core. Synchronous movement between the units achieves uniform distribution of clamping force. The guide groove design constrains the movement trajectory of the ends, ensuring stable clamping posture under punching vibration and impact, avoiding the deflection problem of traditional single-point clamping. The output end of the first drive block passes through the splash guard and connects to the outer shell component, driving the entire clamping device to rotate. This design allows the valve core to have its processing angle adjusted without releasing the clamp, enabling multi-station processing. This ball valve core clamping processing equipment solves the problems of traditional equipment where clamping force relies on manual adjustment and has limited adaptability, and can be adapted to various ball valve cores of different sizes.

[0030] In this utility model, "first" and "second" do not represent a specific quantity or order, but are merely used to distinguish names.
[0031] like Figure 1-4As shown, a ball valve core clamping processing device according to one embodiment of the present invention includes a machine base 1, a punching device 2, a splash guard 3, and a clamping device 4; the punching device 2 is mounted on the machine base 1; the splash guard 3 includes a base 31 and a splash guard 32, the base 31 is mounted on the machine base 1, the splash guard 32 is hinged to the base 31, and a first space is formed between the splash guard 32 and the base 31; the splash guard 32 is provided with an opening 8 for the processing end of the punching device 2 to pass through; the clamping device 4 includes a first driving block 41, a housing component 42, and a plurality of components disposed on the housing component. The clamping unit 43 is located inside the housing component 42; a plurality of guide grooves are formed on the housing component 42; each clamping unit 43 has an end portion for performing a clamping action, the end portion extending through a corresponding guide groove; the plurality of clamping units 43 cooperate to clamp the ball valve core; the housing component 42 is disposed in the first space, the first drive block 41 is disposed on the machine base 1, the output end of the first drive block 41 extends through the splash guard 32 into the first space and connects with the housing component 42, and the first drive block 41 is used to drive the housing component 42 to rotate.
[0032] The aforementioned ball valve core clamping processing equipment forms a closed first space by hinged connection between the splash guard 32 and the base 31, completely enclosing the clamping device 4 and the valve core, effectively isolating them from the external environment. The top of the splash guard 32 has an opening 8, allowing the processing end of the punching device 2 to enter while preventing debris from scattering. Three or more clamping units 43 are distributed inside the outer shell component 42, their ends passing through guide grooves to form an enveloping clamp on the valve core. Synchronous movement between the units achieves uniform distribution of clamping force. The guide groove design constrains the movement trajectory of the ends, ensuring stable clamping posture under punching vibration and impact, avoiding the deflection problem of traditional single-point clamping. The output end of the first drive block 41 passes through the splash guard 32 and connects to the outer shell component 42, driving the clamping device 4 to rotate as a whole. This design allows the valve core to adjust its processing angle without releasing the clamp, enabling multi-station processing. This ball valve core clamping processing equipment solves the problems of traditional equipment where clamping force depends on manual adjustment and has limited adaptability, and can adapt to various ball valve cores of different sizes.
[0033] like Figure 1-2 As shown, in one embodiment, the punching device 2 includes a linear module 21 and a punching machine 22. The linear module 21 is vertically mounted on the machine base 1, and the punching machine 22 is mounted on the moving end of the linear module 21. Thus, the linear module 21 provides high-precision vertical feed, ensuring consistent punching depth and reducing processing errors; the modular design facilitates maintenance and replacement, improving equipment reliability.
[0034] like Figure 2-4As shown, in one embodiment, the outer casing member 42 has a through hole 5 extending vertically through its top and bottom surfaces. This through hole 5 is used to insert the ball valve core to be processed. Thus, the through hole 5 structure achieves axial vertical positioning of the valve core, simplifying the clamping process and shortening auxiliary time; the through-hole design facilitates the natural fall of processing debris, reducing internal chip accumulation.
[0035] like Figure 2-4 As shown, in one embodiment, each clamping unit 43 includes: an end assembly for performing clamping actions, a transmission mechanism for transmitting power, and a power source assembly for providing driving force; wherein the end assembly, the transmission mechanism, and the power source assembly are sequentially connected for power transmission; the power source assembly is used to drive the end assembly to perform clamping actions; the end assembly includes: a fixedly disposed guide rail 431, a slider 432 that can slide along the guide rail 431, and a clamping member 433 for directly contacting and clamping the ball valve core; the guide rail 431 is disposed inside the housing member 42; the guide groove is connected to the guide rail 431; the first end of the slider 432 is fitted in the guide rail 431 and can slide along it, and the second end of the slider 432 extends beyond the guide groove and is fixedly connected to the clamping member 433. Thus, by constraining the movement trajectory of the slider 432 by the guide rail 431, the rigidity of the clamping system is enhanced, effectively resisting the impact force of punching and preventing clamping loosening; the modular components facilitate independent maintenance of the unit.
[0036] like Figure 2-4 As shown, in one embodiment, the transmission mechanism includes a rack 434, a first gear 435, a second gear 436, and a first support shaft 437. The transmission mechanism is housed within the outer casing 42. Both ends of the first support shaft 437 are fixedly connected to the inner wall of the outer casing 42. The first gear 435 and the second gear 436 are both mounted on the first support shaft 437 and can rotate around its axis. The rack 434 is slidably disposed inside the guide rail 431. The slider 432 is fixedly mounted on the rack 434. A clearance window 6 is provided on the side wall of the guide rail 431. Part of the teeth of the first gear 435 passes through the clearance window 6 and meshes with the rack 434. Thus, the meshing of the gear and rack 434 achieves synchronous movement of the multiple clamping units 43, ensuring uniform distribution of clamping force. The clearance window 6 integrates the meshing structure, saving space and achieving high transmission efficiency.
[0037] like Figure 2-4As shown, in one embodiment, the power source assembly includes: an actuating cylinder 438, a second support shaft 439, and a third gear 4310; both ends of the second support shaft 439 are fixedly connected to the inner wall of the outer casing member 42; the third gear 4310 is mounted on the second support shaft 439 and can rotate around its axis, and the third gear 4310 is meshed with the second gear 436; the cylinder body of the actuating cylinder 438 is connected to the inner wall of the outer casing member 42 by a hinge; the piston rod output end of the actuating cylinder 438 is connected to the third gear 4310 by a hinge; the actuating cylinder 438 transmits power by driving the third gear 4310 to rotate. Thus, the cylinder power is amplified in two stages by the gears to provide a stable clamping force; the hinge design compensates for assembly errors and extends cylinder life; the gear transmission avoids the complexity of the hydraulic system.
[0038] like Figure 1 In one embodiment, the machine base 1 is provided with a waste chip channel 7 that runs through the machine base 1 and is connected to the first space. Thus, the waste chip channel 7 directly collects debris from the enclosed space, avoiding manual cleaning and machine downtime; the through structure prevents debris accumulation from affecting the movement of the clamping device 4, ensuring continuous operation.
[0039] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0040] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
