Description

Technical Field

[0001] The present invention relates to the field of machine tools, and particularly to an intelligent processing machine tool for valve production. Background Art

[0002] In the field of valve production and processing, intelligent processing machine tools driven by screw rod structures are widely used. However, during the valve processing, a large amount of debris and coolant will inevitably be generated due to operations such as milling and drilling. From the perspective of mechanical transmission principle, screw rod transmission relies on the precise fit between the screw rod and the nut to achieve precise displacement. But when a large amount of debris falls onto the screw rod, the debris will be embedded in the meshing gap between the screw rod and the nut, destroying its original smooth transmission, increasing the transmission resistance, and resulting in a decrease in transmission accuracy. At the same time, the coolant has strong fluidity and solubility. It will quickly wash away the lubricating oil on the surface of the screw rod or mix with the lubricating oil to make it deteriorate and pollute. And the lubricating oil is crucial for the screw rod structure. It can not only reduce the friction coefficient, reduce wear, but also play a role in heat dissipation and buffering. Once the lubricating oil fails, the screw rod is extremely prone to increased wear, jamming, or even fracture under high-speed operation and high-load work, seriously affecting the normal operation of the screw rod structure. Summary of the Invention

[0003] In order to overcome the disadvantages that during the processing of valves by existing machine tools, a large amount of debris and coolant will be generated, and for machine tools driven by screw rod structures, the debris and coolant will fall onto the screw rod in large quantities, the presence of debris will affect the transmission of the screw rod structure, and the coolant will wash away or pollute the lubricating oil on the screw rod, thus causing the screw rod structure to malfunction or be damaged, the present invention provides an intelligent processing machine tool for valve production.

[0008] In a preferred embodiment of the present invention, no support rod is fixedly connected to the lower sides of the deformation parts at the leftmost and rightmost positions. The left end of the first telescopic rod at the leftmost position, the deformation part at the leftmost position are connected to the processing component mounting seat, and the first telescopic rod and the processing component mounting seat are hinged. The right end of the first telescopic rod at the rightmost position, the deformation part at the rightmost position are connected to the fixture mounting seat, and the first telescopic rod and the fixture mounting seat are hinged.

[0009] In a preferred embodiment of the present invention, the connector includes a connecting shaft, a first hinged part and a second hinged part; the support rod is connected to the connecting shaft through a connecting rod; the first hinged part and the second hinged part are rotatably connected to the connecting shaft; the first hinged part is connected to the telescopic part of the first telescopic rod on the left side, and the second hinged part is connected to the telescopic part of the first telescopic rod on the right side.

[0010] In a preferred embodiment of the present invention, the connector further includes a limiting plate and a pneumatic telescopic part; a limiting plate is fixedly connected to the upper side of the first hinged part; a slot is opened in the second hinged part, and a pneumatic telescopic part is installed in the slot.

[0011] In a preferred embodiment of the present invention, a debris cleaning component is further included on one side of the folding plate.

[0012] In a preferred embodiment of the present invention, the support rod, the connector and the first telescopic rod are arranged under the folding plate.

[0013] In a preferred embodiment of the present invention, a shielding part and a blowing component are further included; shielding parts are connected to both sides of the folding plate; a blowing component is installed on the side of the second hinged part facing the shielding part.

[0014] In a preferred embodiment of the present invention, the shielding part includes a shielding cloth, a second telescopic rod and a counterweight; the deformation part is connected to the second telescopic rod; a counterweight is fixedly connected to the bottom of the second telescopic rod; a shielding cloth is connected between the second telescopic rods.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] The present invention innovatively sets the folding plate, a key protective structure. The folding plate spans between the processing component mounting seat and the fixture mounting seat, effectively covering the lead screw area. During the processing, the dropped debris and coolant first contact the folding plate. Due to its own gravity, the debris is temporarily stored on the surface of the folding plate, while the coolant has fluidity and will flow away naturally along the front and back sides of the folding plate, thus avoiding the direct contact between the debris and the coolant with the lead screw, and fundamentally eliminating the hidden danger of damage to the lead screw transmission and lubrication system.

[0017] When the folding plate moves, the first telescopic rod can adaptively expand and contract according to the stretching or folding of the folding plate to ensure the stability of the structure. The limiting plate is installed on the upper side of the first hinge part. When the folding plate performs stretching or folding actions, by contacting the upper side surface of the second hinge part, the rotation range of the connecting shaft is restricted, so as to ensure that the middle part of the folding plate will not sink downward and maintain a horizontal state. In addition, when the tool performs the second moving step, that is, when processing the valve and continuously moving rightward for feeding, as a large amount of debris accumulates in the troughs of the folding plate, it may occur that the debris gets stuck in the folding plate. At this time, the pneumatic telescopic part plays a key role. Its telescopic part will slowly extend as the tool moves rightward and jack up the limiting plate upward. This action causes the first hinge part, the second hinge part and the connecting shaft to rotate relatively, making the adjacent two first telescopic rods present a flat "eight" shape state. Furthermore, during the subsequent folding process of the folding plate, the distance between the flat parts of the folding plate gradually expands or remains unchanged. Under the coordinated action of multiple connectors, the telescopic rods as a whole are in an upward-arching state, driving the folding plate as a whole to arch upward, effectively avoiding the debris from getting stuck or damaging the flat parts when the tool continues to move rightward, and ensuring the normal operation and service life of the folding plate.

[0018] The present invention has multiple advantages in arranging the support rod, the connector and the first telescopic rod under the folding plate. On the one hand, this layout method will not hinder the pushing work of the scraping plate, ensuring the smooth progress of the cleaning process; on the other hand, the folding plate can effectively protect the support rod, the connector and the first telescopic rod from being interfered by debris and coolant, extend the service life of these components, and improve the reliability of the entire protection structure.

[0019] The present invention adds a shielding part and a blowing component. When the folding plate folds and stretches, it drives the shielding cloth to move synchronously. The main function of the shielding part is to shield the lower sides of both sides of the folding plate, forming a physical barrier to prevent debris and coolant from splashing onto the lead screw structure from here. At the same time, when the coolant flows away from both sides of the folding plate, the shielding part can also play a guiding role to further reduce the splashing range of the coolant. The blowing component is installed on one side of the second hinge part facing the shielding part, and intermittently blows air at the shielding cloth, causing the shielding cloth to swing continuously. This swinging can effectively prevent debris from remaining on the shielding cloth, keep the shielding cloth clean, and ensure that it can always play a good shielding role.

Detailed implementation manners

[0029] The present invention will be specifically described below with reference to the accompanying drawings.

[0030] Embodiment 1

[0031] An intelligent processing machine tool for valve production, as Figures 1 - 8 shown, includes a mounting table 1, a lead screw drive assembly 2, a processing component mounting seat 3 and a fixture mounting seat 4; the lead screw drive assembly 2 is mounted on the mounting table 1, and a processing component mounting seat 3 is fixedly connected to the moving part of the lead screw drive assembly 2, and processing components for milling and drilling the valve are mounted on the processing component mounting seat 3; a fixture mounting seat 4 is mounted on the right side of the mounting table 1, and a fixture for clamping and fixing the valve is mounted on the fixture mounting seat 4;

[0032] It further includes a folding plate 5; a folding plate 5 is mounted between the processing component mounting seat 3 and the fixture mounting seat 4; the lead screw structure is shielded by the folding plate 5.

[0033] It should be noted that the processing component mounting seat 3 can be mounted with, but not limited to, milling processing components and drilling processing components.

[0034] As Figure 6As shown, the folding plate 5 is composed of a flat part 51 and a deformable part 52. When the folding plate 5 is stretched or folded, the deformable part 52 deforms.

[0035] It further includes a support rod 101, a connector 102, and a first telescopic rod 103. A support rod 101 is fixedly connected to the lower side of the deformable part 52 at the wave crest position. The support rod 101 is connected to the connector 102 through a connecting rod 1011. A first telescopic rod 103 is fixedly connected between adjacent connectors 102.

[0036] As Figure 1 、 Figure 5 shown, support rods 101 are not fixedly connected to the lower sides of the leftmost and rightmost deformable parts 52. The left end of the first telescopic rod 103 at the leftmost side, the leftmost deformable part 52 are connected to the processing component mounting seat 3, and the left end of the first telescopic rod 103 at the leftmost side is specifically hinged to the processing component mounting seat 3. The right end of the first telescopic rod 103 at the rightmost side, the rightmost deformable part 52 are connected to the fixture mounting seat 4, and the right end of the first telescopic rod 103 at the rightmost side is specifically hinged to the fixture mounting seat 4.

[0037] As Figure 6 、 Figure 7 shown, the connector 102 includes a connecting shaft 1021, a first hinged part 1022, and a second hinged part 1023. The support rod 101 is connected to the connecting shaft 1021 through the connecting rod 1011. The first hinged part 1022 and the second hinged part 1023 are rotatably connected to the connecting shaft 1021. The first hinged part 1022 is connected to the telescopic part of the first telescopic rod 103 on the left side, and the second hinged part 1023 is connected to the telescopic part of the first telescopic rod 103 on the right side.

[0038] The connector 102 further includes a limiting plate 1024 and a pneumatic telescopic part 1025. A limiting plate 1024 is fixedly connected to the upper side of the first hinged part 1022. A slot is opened in the second hinged part 1023, and the pneumatic telescopic part 1025 is installed in the slot.

[0039] It further includes a debris cleaning component arranged on one side of the folding plate 5. The debris temporarily stored on the folding plate 5 is cleaned by the debris cleaning component. The debris cleaning component can be composed of a scraper with the same shape as the folding plate 5 after stretching and an electric push rod for pushing the scraper to move. The debris temporarily stored on the upper side of the folding plate 5 is pushed away by pushing the scraper to complete the cleaning work.

[0040] During the machining process of the existing machine tool for valves, a large amount of debris and coolant will be generated. For a machine tool driven by a lead screw structure, the debris and coolant will fall onto the lead screw in large quantities. The presence of debris will affect the transmission of the lead screw structure, and the coolant will wash away or contaminate the lubricating oil on the lead screw, which will cause the lead screw structure to malfunction or be damaged. To address the above problems, we provide an intelligent machining machine tool for valve production that can protect the lead screw structure.

[0041] It should be noted first that the rightward movement of the machining component on the machining component mounting seat 3 for valve machining is divided into two movement steps:

[0042] The first movement step is that the tool on the machining component mounting seat 3 moves rightward to align with the valve;

[0043] The second movement step is that the tool on the machining component mounting seat 3 processes the valve and continuously moves rightward for feeding.

[0044] When the present invention works, the machining components for milling and drilling the valve are installed on the machining component mounting seat 3; the fixture for clamping and fixing the valve is installed on the fixture mounting seat 4. When milling and drilling the valve, control the lead screw drive assembly 2 to drive the machining components on the machining component mounting seat 3 to perform specific machining work on the valve. The generated debris and coolant fall downward, and the folding plate 5 is used to shield and protect the lead screw structure. The debris and coolant are intercepted by the folding plate 5. The debris can be temporarily stored on the folding plate 5, and the coolant flows away from the front and back sides of the folding plate 5;

[0045] It should be noted that when the machining component mounting seat 3 moves left and right, the folding plate 5 performs stretching or folding actions. When the folding plate 5 performs stretching or folding actions, the first telescopic rod 103 adapts to stretch and contract. At the same time, because the bottom of the right side of the initial limit plate 1024 contacts the upper side of the second hinge portion 1023, the connector 102 can ensure that when the folding plate 5 performs stretching or folding actions, the first telescopic rod 103 is in a straight state as a whole, so that the middle part of the folding plate 5 will not sink downward and can maintain a horizontal state.

[0046] Further, when the tool performs the second movement step (the tool on the machining component mounting base 3 processes the valve and continues to move rightward for feeding), there will be more and more debris on the folding plate 5, and a large amount of debris will get stuck in the troughs of the folding plate 5. When the folding plate 5 performs the folding action, the space between the flat parts 51 will become smaller and smaller, which will cause the debris in the troughs to jam the folding plate 5, thereby affecting the folding action of the folding plate 5 or damaging the folding plate 5. Based on this problem, when the tool performs the second movement step, the telescopic part of the pneumatic telescopic part 1025 can be controlled to slowly extend as the tool continues to move rightward, so as to jack up the limit plate 1024 upward. At this time, the first hinge part 1022, the second hinge part 1023 and the connecting shaft 1021 rotate relative to each other, so that the adjacent two first telescopic rods 103 present a flat "eight" shape. In this way, during the subsequent folding process of the folding plate 5, the distance between the flat parts 51 can be gradually enlarged or remain unchanged. Under the simultaneous action of multiple connectors 102, the first telescopic rods 103 as a whole are in an upward arched state, and then the folding plate 5 as a whole is in an upward arched state, so as to prevent the debris from jamming or damaging the flat parts 51 when the tool continues to move rightward;

[0047] Further, after each machining action of the machining component is completed, that is, after the machining component moves leftward and resets, the folding plate 5 is stretched, and then the debris cleaning assembly is controlled to clean the debris temporarily stored on the folding plate 5.

[0048] Arranging the support rod 101, the connector 102 and the first telescopic rod 103 under the folding plate 5 can facilitate the pushing work of the scraper of the debris cleaning assembly, and the folding plate 5 protects the support rod 101, the connector 102 and the first telescopic rod 103 from being interfered by debris and coolant.

[0049] Embodiment 2

[0050] On the basis of Embodiment 1, as Figures 1 - 8 shown, it further includes a shielding member 201 and a blowing assembly 202; shielding members 201 are connected to both sides of the folding plate 5; a blowing assembly 202 is installed on the side of the second hinge part 1023 facing the shielding member 201.

[0051] As Figure 3 、 Figure 4 shown, the shielding member 201 includes a shielding cloth 2011, a second telescopic rod 2012 and a counterweight 2013; the deformation part 52 is connected to the second telescopic rod 2012; a counterweight 2013 is fixedly connected to the bottom of the second telescopic rod 2012, and the second telescopic rod 2012 is telescoped by the counterweight 2013. The counterweight 2013 contacts the mounting table 1 by gravity; a shielding cloth 2011 is connected between the second telescopic rods 2012.

[0052] Further, in the present invention, the shielding member 201 shields the lower sides of both sides of the folding plate 5, preventing debris and coolant from splashing onto the lead screw structure from here. At the same time, when the coolant flows away from both sides of the folding plate 5, it can also be guided by the shielding member 201 to further reduce splashing. The second telescopic rod 2012 in the shielding member 201 is stretched under the action of the counterweight 2013, bringing the counterweight 2013 into contact with the mounting table 1. At the same time, the second telescopic rod 2012 serves as the framework of the shielding cloth 2011 to support the shielding cloth 2011, and drives the shielding cloth 2011 to fold and stretch when the folding plate 5 folds and stretches. Further, by intermittently blowing air onto the shielding cloth 2011 through the air blowing assembly 202, the shielding cloth 2011 can be made to swing continuously, thereby preventing debris from remaining on the shielding cloth 2011.

In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims of this application.
