Description

Technical Field

[0001] This utility model relates to the field of machining technology, specifically to a positioning and clamping device for CNC machines. Background Technology

[0002] During CNC machining, the placed machining tray needs to be fixed to position the workpiece. Existing positioning methods, such as the scheme in patent publication CN 220613153 U, employ a first air vent to cut off air while a second air vent allows air in. This increases the air pressure between the pusher and the piston cover. Since the piston cover is fixed, the air pressure drives the pusher downwards. Because the zero-point pull plate is locked to the push rod by screws, the zero-point pull plate is pulled downwards, thus pulling the fixture tray downwards and locking it. In other words, a spring provides downward pulling force to pull the fixture tray downwards and lock it. However, this method uses spring tension for locking, rather than a fixed lock, which can cause wobbling during machining. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, such as unstable fixing, the purpose of this utility model is to provide a stable and fixed positioning clamping device for CNC machines.

[0004] To solve the above problems, this utility model provides the following technical solution:

[0005] A positioning and clamping device for a CNC machine includes: a CNC machine;

[0006] The substrate is mounted inside the CNC equipment;

[0007] A support member, mounted on the base plate, is used to support the processing tray;

[0008] A carrier component, disposed on the substrate, is used to drive the processing tray to contact and detach from the support component;

[0009] A clamping assembly, mounted on the substrate, is used to clamp and fix the processing tray, and the clamping assembly can be located away from or close to the processing tray;

[0010] When the bearing component moves toward the support, the pressing component moves toward the support. When the processing tray comes into contact with the support, the pressing component contacts the processing tray and presses the processing tray onto the support for fixation. When the pressing component moves away from the processing tray, the bearing component disengages the processing tray from the support, and the processing tray can be removed from the CNC equipment.

[0011] In some embodiments, the positioning and clamping device for CNC machines further includes a limiting component disposed on the substrate for limiting the movement and positioning of the processing tray.

[0012] In some embodiments, the limiting component includes a first blocking member and a positioning member;

[0013] The first blocking element is used to block the movement of the processing pallet;

[0014] Once the processing pallet has moved to the appropriate position on the CNC machine, the first blocking element restricts the processing pallet from moving further.

[0015] The positioning element is mounted on the base plate and is used for aligning the processing pallet;

[0016] As the processing pallet moves toward the support, the positioning element aligns the processing pallet.

[0017] In some embodiments, there are two pressing components, which are respectively located on both sides of the processing tray;

[0018] Each of the aforementioned clamping components includes a clamping element and a driving element;

[0019] The driving component is mounted on the base plate, and the clamping component is mounted on the driving component. The driving component drives the clamping component to move, causing the processing tray to be clamped by the clamping component or to separate the processing tray from the clamping component.

[0020] In some embodiments, the driving component includes a limiting rod, a cylinder, and a connecting plate;

[0021] The cylinder is mounted on the base plate, and the connecting plate is fixed to the piston rod of the cylinder;

[0022] The limiting rod is installed on the connecting plate and is used to move the connecting plate along the direction of piston rod movement.

[0023] In some embodiments, the clamping element includes a connecting block and a clamping block;

[0024] The connecting block is installed and fixed to the connecting plate, and the clamping block is installed and fixed to the connecting block. The clamping block is used to clamp and fix the processing pallet.

[0025] In some embodiments, the carrier includes a first carrier plate and a second carrier plate;

[0026] The first carrier plate and the second carrier plate are respectively mounted on one of the connecting blocks; the first carrier plate and the second carrier plate are lower than the clamping block, the distance between the first carrier plate and the clamping block on the corresponding side is greater than the thickness of the processing tray, and the distance between the second carrier plate and the clamping block on the corresponding side is greater than the thickness of the processing tray.

[0027] In some embodiments, the number of positioning elements is greater than or equal to two; the upper end of the positioning element is tapered.

[0028] In some embodiments, the number of supports is greater than or equal to three, and the axes of the supports are not located on the same plane.

[0029] In some embodiments, the support member is provided with a detection hole;

[0030] When the processing tray is placed on the support and pressed down, the processing tray will block the detection hole.

[0031] The beneficial effects of this utility model are: the carrier component makes the processing tray contact or detach from the support component, and then the pressing component presses the processing tray onto the support component for support and fixation. This facilitates the removal and insertion of the processing parts into and out of the CNC equipment, and also facilitates the support and fixation of the processing tray and the stability of the processing tray.

[0057] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0058] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0059] For ease of description of the first, second, and third directions in the embodiments of this application, the first direction is the left-right direction in the figures, the second direction is the front-back direction in the figures, and the third direction is the up-down direction in the figures. The x-axis arrow direction is referred to as the "right" direction, the y-axis arrow direction as the "up" direction, and the z-axis arrow direction as the "back" direction, but these are not the sole limitations in the actual application of this application.

[0060] like Figure 1-3 as well as Figure 7 As shown, this embodiment provides a positioning and clamping device for a CNC machine, which includes a CNC machine 1, a base plate 101, a support member 2, a limiting component 3, and a pressing component 4. The base plate 101 is installed inside the CNC machine 1; the support member 2 is installed on the base plate 101 to support the processing tray 102; the limiting component 3 is disposed on the base plate 101 to restrict the movement and positioning of the processing tray 102; the pressing component 4 is installed on the base plate 101 to press and fix the processing tray 102, and the pressing component 4 can move away from and towards the processing tray 102; when the pressing component 4 moves towards the processing tray 102, the pressing component 4 presses the processing tray 102 against the support member 2 for fixation; when the pressing component 4 moves away from the processing tray 102, the pressing component 4 separates from the processing tray 102, and the processing tray 102 can be removed from the CNC machine 1. In other words, before the CNC equipment 1 performs processing, the limiting component 3 first restricts and positions the processing tray 102 that carries the workpiece to be processed, ensuring that the processing tray 102 is installed in the accurate position and preventing the workpiece to be processed from being skewed; then the pressing component 4 presses the processing tray 102 onto the support component 2 for support and fixation, ensuring the stability of the processing tray 102; through limiting and pressing, the operation is simple and convenient.

[0061] like Figure 1-5As shown, in this embodiment, there are two pressing components 4, located on both sides of the processing tray 102. Each pressing component 4 includes a clamping member 410 and a driving member 420. The driving member 420 is mounted on the base plate 101, and the clamping member 410 is mounted on the driving member 420. The driving member 420 drives the clamping member 410 to move, so that the processing tray 102 is pressed by the clamping member 410 or the processing tray 102 is separated from the clamping member 410. That is, the processing workpiece is pressed by the pressing components on both sides to ensure the pressing stability of the processing tray 102 and ensure the normal operation of processing.

[0062] like Figure 3-5 As shown, in one embodiment, the driving member 420 includes a limiting rod 421, a cylinder 422, and a connecting plate 423; the cylinder 422 is mounted on the base plate 101, and the connecting plate 423 is fixed to the piston rod of the cylinder 422; the limiting rod 421 is mounted on the connecting plate 423 and is used to move the connecting plate 423 relative to the piston rod in the direction of movement. The clamping member 410 includes a connecting block 411 and a clamping block 412; the connecting block 411 is fixedly mounted to the connecting plate 423, and the clamping block 412 is fixedly mounted to the connecting block 411, and the clamping block 412 is used to clamp and fix the processing tray 102. The cylinder 422 is used for driving, and the limit rod 421 is used to ensure that the connecting plate 423 lifted by the cylinder 422 will not be tilted, thus ensuring the stability of the connecting plate 423 during driving. Finally, the clamping block 412 is used to clamp and fix or separate and move the processing tray 102. That is, when the processing tray 102 is clamped and fixed, it is ensured that the clamping block 412 is pressed as a whole, and the processing tray 102 will not be loosely clamped due to the clamping block 412 being tilted, which would cause errors during processing.

[0063] A spring is fitted on the limit rod 421. The spring exerts a downward pulling force on the connecting plate 423. When the cylinder 422 suddenly stops supplying air, the spring will pull the connecting plate 423 downward, causing the connecting plate 423 to press the processing tray 102 through the clamping block 411, thus preventing the processing tray 102 from detaching.

[0064] The cylinder 422 applies a pressure of 3 MPa to the processing tray 102 via the connecting plate 423 and the clamping block 412, ensuring that the processing tray 102 is subjected to sufficient pressure and has sufficient stability. This prevents the processing tray 102 from shaking due to insufficient pressure during processing, which would affect its processing accuracy.

[0065] In other embodiments, the cylinder 422 can also be replaced by a drive component 420 such as an electric cylinder or a hydraulic cylinder; both facilitate the clamping and fixing or the separation and movement of the processing tray 102.

[0066] In other embodiments, the cylinder 422 can also be replaced by a lead screw and nut. The lead screw is mounted on the base plate 101 and driven by electricity, and the nut is mounted on the connecting plate 423. The connecting plate 423 can be moved up and down by the lead screw and nut, thereby enabling the processing tray 102 to be pressed and fixed or separated by the clamping block 412. Furthermore, the use of a lead screw and nut can also ensure that the connecting plate 423 has a locking effect after moving up and down, preventing the clamping from loosening due to power failure or air failure during processing.

[0067] like Figure 1-5 As shown, in this embodiment, the positioning and clamping device for the CNC machine also includes a carrier 5, which is installed on the holding assembly 4. The carrier 5 moves the processing tray 102 as the holding assembly 4 moves. When the holding assembly 4 moves the processing tray 102 toward the support 2, the processing tray 102 contacts the support 2 and separates from the carrier 5. Then, the holding assembly 4 presses the processing tray 102. When the holding assembly 4 moves away from the processing tray 102, the carrier 5 separates the processing tray 102 from the support 2, and the processing tray 102 can move out of the CNC machine 1. That is to say, when the holding assembly 4 separates from the processing tray 102, the carrier 5 lifts the processing tray 102, making it easier to remove the processing tray 102 from the CNC machine 1. Similarly, it is also easier to push the processing tray 102 into the CNC machine 1 and be supported by the carrier 5. In other words, the carrier 5 facilitates the movement of the processing tray 102 in and out of the CNC machine 1.

[0068] like Figure 2-5 As shown, in this embodiment, the carrier 5 includes a first carrier plate 501 and a second carrier plate 502, which are respectively mounted on a connecting block 411. The first carrier plate 501 and the second carrier plate 502 are lower than the clamping block 412. The distance between the first carrier plate 501 and the corresponding clamping block 412 is greater than the thickness of the processing tray 102. Similarly, the distance between the second carrier plate 502 and the corresponding clamping block 412 is greater than the thickness of the processing tray 102. By using a processing pallet 102 with a thickness smaller than the distance between the first carrier plate 501 and the clamping block 412, as well as the distance between the second carrier plate 502 and the clamping block 412, the processing pallet 102 can be easily moved between the first carrier plate 501 and the clamping block 412 and the second carrier plate 502 and the clamping block 412 without getting stuck. Furthermore, by using the first carrier plate 501 and the second carrier plate 502 to jointly support the processing pallet 102, it is ensured that the processing pallet 102 will not tilt due to unilateral support.

[0069] like Figure 2-3As shown, in this embodiment, the first carrier plate 501 and the second carrier plate 502 are each provided with a plurality of first rollers 503, and the first carrier plate 501 and the second carrier plate 502 contact the processing tray 102 via the first rollers 503. By using the arrangement of the first carrier plate 501 and the second carrier plate 502, the friction between the processing tray 102 and the first carrier plate 501 and the second carrier plate 502 can be reduced when the processing tray 102 moves in and out of the CNC machine 1, thereby reducing the wear of the processing tray 102 and ensuring the normal operation of subsequent operations.

[0070] like Figure 2-3 As shown, in one embodiment of the limiting component 3, the limiting component 3 includes a first blocking member 301; the first blocking member 301 is used to block the movement of the processing tray 102; after the processing tray 102 moves to the corresponding position towards the CNC machine 1, the first blocking member 301 restricts the processing tray 102 from continuing to move. By using the limiting component 3, it is possible to avoid the problem of excessive movement of the processing tray 102 during the process of moving the processing tray 102 inward towards the CNC machine 1.

[0071] like Figure 2-3 As shown, in one embodiment of the limiting component 3, the first blocking member 301 includes a vertical plate and a blocking block. The vertical plate is mounted on the base plate 101, and the mounting block is mounted on the vertical plate. The mounting block is a buffer member and does not deform excessively. When the processing tray 102 moves inward, it plays a blocking and limiting role, thereby preventing the processing tray 102 from being pushed and causing collisions that could lead to deformation and affect its later use.

[0072] In one embodiment of the limiting component 3, the first blocking member 301 further includes a fixing block, a spring, a contact block, and a sliding rod. The fixing block is mounted on the base plate 101, the sliding rod is mounted on the fixing block, the contact block is mounted on the sliding rod, and a spring is sleeved on the sliding rod. The spring exerts a forward force on the contact block via the sliding rod. That is, after the processing tray 102 moves into the CNC machine 1, it contacts the contact block. The contact block causes the spring to move backward, thus blocking the processing tray 102. When the processing tray 102 is released, the spring pushes the processing tray 102 to move via the contact block, thus limiting the movement of the processing tray 102. When the processing tray 102 pushes the contact block and then the spring, the deformation of the spring prevents the processing tray 102 from colliding with the contact block, thus preventing the processing tray 102 from deforming during the push and affecting its later use.

[0073] like Figure 4-8As shown, in another embodiment of the limiting component 3, the pressing component 4 is provided with a limiting groove 424; the limiting component 3 also includes a second blocking member 303 and a correction member 304; the first carrier plate 501 and the second carrier plate 502 are installed in the limiting groove 424 and slide, and after sliding into the CNC equipment 1, the first carrier plate 501 and the second carrier plate 502 stop sliding; the first carrier plate 501 and the second carrier plate 502 are located inside the CNC equipment 1 and are fixedly connected by the second blocking member 303, the upper side of the second blocking member 303 is higher than the upper side of the first carrier plate 501 and the second carrier plate 502, the second blocking member 303 causes the first carrier plate 501 and the second carrier plate 502 to move synchronously, the second The blocking member 303 can block the movement of the processing tray 102; the correction member 304 is respectively installed on the first carrier plate 501 and the second carrier plate 502 to gather the processing tray 102 towards the center; when the processing tray 102 is pushed into the CNC equipment 1, the processing tray 102 moves onto the first carrier plate 501 and the second carrier plate 502 and contacts the second blocking member 303. The processing tray 102 pushes the first carrier plate 501 and the second carrier plate 502 inward through the second blocking member 303. When the processing tray 102 moves the first carrier plate 501 and the second carrier plate 502, the correction member 304 will touch the processing tray 102, causing the processing tray 102 to gather towards the center. In other words, when the processing tray 102 moves into the CNC machine 1, it first lands on the first carrier plate 501 and the second carrier plate 502. The processing tray 102 then contacts the second blocking plate and, via the second blocking member 303, causes the first carrier plate 501 and the second carrier plate 502 to move together into the CNC machine 1 through the limiting grooves 424. Once in the appropriate position, the limiting grooves 424 block the movement of the first carrier plate 501 and the second carrier plate 502. At this point, simply stopping the pushing of the processing tray 102 is sufficient. When the first carrier plate 501 and the second carrier plate 502 are pushed, the correction member 304 on the first carrier plate 501 and the second carrier plate 502 is triggered. The correction member 304 causes the processing tray 102, which may be skewed, to converge towards the center, thereby preventing skewness and thus preventing any impact on processing accuracy.

[0074] like Figure 4-8As shown, in another embodiment of the limiting component 3, the correction component 304 includes a support block 305, a push rod 306, a straight rod 308, and a compression spring 309; the holding component 4 is provided with a push block 425; the support block 305 is respectively installed on the corresponding first carrier plate 501 and second carrier plate 502, the straight rod 308 is installed on the support block 305, the push rod 306 is installed on the straight rod 308, and the compression spring 309 is sleeved on the straight rod 308. The compression spring 309 pulls the push rod 306 to move away from the processing tray 102 via the straight rod 308; the connecting block 411 is equipped with a push block 425, when the processing tray 10 2. When the first carrier plate 501 and the second carrier plate 502 are moved by the second blocking member 303, the first carrier plate 501 and the second carrier plate 502 drive the push rod 306 to move. When the straight rod 308 contacts the push block 425, the push block 425 pushes the push rod 306 towards the processing tray 102 via the straight rod 308, until the straight rod 308 moves to the middle position of the push block 425, that is, the inner middle of the push block 425 is the limit position for pushing the straight rod 308, so that the processing tray 102 is moved towards the center. This can prevent the processing tray 102 from shifting during the movement, which would affect the subsequent processing. The use of a tension spring ensures that the push rod 306 always moves away from the processing tray 102, which can prevent the processing tray 102 from being difficult to place when it is placed towards the first carrier plate 501 and the second carrier plate 502. Furthermore, with the extreme position being the inner middle of the push block 425, when the processing pallet moves outward, the push block 425 pushes the straight rod 308 to make way, and the processing pallet 102 can be moved out of the CNC equipment 1.

[0075] The first carrier plate 501 and the second carrier plate 502 are provided with a stop block 504, which can stop the movement when the first carrier plate 501 and the second carrier plate 502 move inward or outward.

[0076] like Figure 4-8 As shown, in another embodiment of the limiting component 3, multiple magnets 310 are mounted on the upper sides of the first carrier plate 501 and the second carrier plate 502. When the processing tray 102 moves outward from the CNC machine 1, the processing tray 102 moves the first carrier plate 501 and the second carrier plate 502 via the magnets 310. By using the attraction between the magnets 310 and the processing tray 102, the first and second trays can be moved outward when the processing tray 102 moves outward from the CNC machine 1, making it easier for the next processing tray 102 to be placed in; it can also prevent the processing tray 102 from shaking back and forth when it moves inward from the CNC machine 1 under the attraction of the magnets 310.

[0077] like Figure 2-5As shown, in this embodiment, the limiting component 3 further includes a positioning element 311; the positioning element 311 is mounted on the base plate 101 and is used for aligning the processing tray 102; when the processing tray 102 moves towards the support member 2, the positioning element 311 moves into the corresponding limiting hole on the processing tray 102, thereby causing the processing tray 102 to be corrected. That is, when the processing tray 102 moves towards the support member 2, the positioning element 311 ensures that the furniture processing tray 102 is accurately positioned, guaranteeing the processing accuracy of the subsequent processed parts.

[0078] like Figure 2-5 As shown, in this embodiment, the upper end of the positioning member 311 is tapered to prevent the processing tray 102 from failing to be placed due to slight errors.

[0079] like Figure 2-5 As shown, in this embodiment, the number of positioning members 311 is greater than or equal to two, which can prevent the processing tray 102 from rotating around the positioning member 311 after the processing tray 102 is placed in.

[0080] The positioning element 311 is columnar, and the fitting clearance between the positioning element 311 and the corresponding limiting hole on the processing tray 102 is between 0.01mm and 0.02mm; thereby ensuring that the processing error during processing is between 0.01 and 0.02mm, so as to achieve good processing accuracy.

[0081] like Figure 2-5 As shown, in this embodiment, the number of support members 2 is greater than or equal to three, and the axes of the support members 2 are not located on the same plane. When the processing tray 102 is placed on the support members 2, using more than or equal to three can better ensure the stability during placement and pressing.

[0082] like Figure 2-5 As shown, in one embodiment, the support member 2 is provided with a detection hole 201. When the processing tray 102 is placed on the support member 2 and pressed, the processing tray 102 blocks the detection hole 201. The processing tray 102 is pressed tightly by detecting whether the detection hole is breathable.

[0083] like Figure 9-10As shown, in another embodiment, the support member 2 includes a support disk 202 and a cylindrical block 203. The support disk 202 is fixed on the base plate 101, and the cylindrical block 203 is fixed on the support disk 202. The upper end of the cylindrical block 203 is chamfered, and a cylinder 103 is fixed to the lower side of the processing tray 102. The cylinder 103 can be fitted onto the cylindrical block 203. The engagement between the cylinder 103 and the support column 202 is a zero-point fixture engagement. After the cylinder 103 contacts the support disk 202, the processing tray 102 is supported. That is, when the processing tray 102 moves downward, the cylinder 103 on the processing tray 102 is fitted onto the cylindrical block 203, and the cylinder 103 stops moving after contacting the support disk 202, making the installation of the processing tray 102 more convenient.

[0084] The fitting accuracy between the cylindrical block 203 and the cylinder 103 is less than 0.01mm, thereby ensuring that the machining error during processing is less than 0.01mm, making its machining accuracy more precise.

[0085] like Figure 1-5 As shown, in this embodiment, the positioning and clamping device for the CNC machine also includes a conveyor 8. The conveyor 8 is mounted on the base plate 101 and located at the opening of the CNC equipment 1. The conveyor 8 has a second roller 801. The processing tray 102 is moved to or out of the CNC equipment 1 via the conveyor 8, which is convenient to use.

[0086] like Figure 1 As shown, in this embodiment, the positioning and clamping device for the CNC machine also includes a cover 312, which covers the drive assembly and moves up and down with the connecting plate 423. The cover 312 is used to prevent machining debris and coolant from falling onto the drive assembly, making it difficult to clean.

[0087] As can be seen from the above embodiments, the positioning and clamping device for a CNC machine is the CNC equipment 1 that can be used for manual conveying, such as... Figure 11-12 As shown; it can also be used in automatic CNC equipment 1, such as Figure 13 As shown.

[0088] like Figure 14-15As shown in the above embodiment, after the metal workpiece placed on the processing tray 102 is processed, the processing tray 102 is controlled to slide towards the transport trolley 9. In order to ensure that the processing tray 102 can slide smoothly onto the transport trolley 9, the transport trolley 9 in this solution needs to remain relatively stationary with the CNC machine tool. Based on this, this solution also includes a locking component 6, which includes a pressing block 601, a hinge rod 602, a hinge spring 603, a driving block 604, and a locking block 605. The middle end of the hinge rod 602 is rotatably disposed inside the transport trolley 9. It should be noted that when the processing tray 102 is located on the transport trolley 9, the hinge rod 602 is in a horizontal state. The two ends of the hinge spring 603 are respectively connected to one end of the hinge rod 602 and the transport trolley 9. The pressing block 601 can be vertically slidably disposed between the two transport positioning components 1. The bottom of the pressing block 601 slides along the axial direction of the hinge rod 602 and is in contact with the hinge rod 602. One end is hinged; the drive block 604 is vertically slidably mounted on the bottom of the transport trolley 9 near the CNC machine tool. The top of the drive block 604 slides along the axis of the hinge rod 602 and is hinged to the other end of the hinge rod 602. The bottom of the drive block 604 has a locking groove. The locking block 605 is connected to the fixed frame 101. The drive block 604 can lock or release its restrictive engagement with the locking block 605 through the locking groove. It is worth noting that when the processing tray 102 moves from the transport trolley 9 into the CNC machine tool, the hinge rod 602, which is in a horizontal state, will change from its original horizontal state to an inclined state due to the action of the hinge spring 603. This causes the pressing block 601 to move towards the top of the transport trolley 9, while the drive block 604, which is located at the other end of the hinge rod 602, will move towards the bottom until the locking groove of the drive block 604 and the locking block 605 cooperate with each other, so that the transport trolley 9 and the CNC machine tool remain relatively stationary. It is also worth noting that after the transport trolley 9 moves to the CNC machine tool and comes into contact with it, and after the transport trolley 9 is restricted by the two transport positioning components 1, the drive block 604 is located on top of the locking block 605.

[0089] Furthermore, in this design, the top of the pressing block 601 is tilted, and its vertical height decreases as viewed from the direction perpendicular to the front face of the CNC machine tool towards the CNC machine tool. After the metal workpiece on the processing tray 102 is processed, it will be pushed back from the CNC machine tool to the transport trolley 9. Due to the tilted top of the pressing block 601, and the height of the tilted end of the pressing block 601 being between the height of the bottom surface of the processing tray 102, as the processing tray 102 moves to the transport trolley 9, the processing tray 102 will control the pressing block 601 to move towards the bottom, causing the hinge rod 602 to change from an tilted state to a horizontal state, and the drive block 604 to release its restrictive engagement with the locking block 605.

[0090] like Figure 14-15 As shown in the above embodiments, to ensure the working environment inside the CNC machine tool and prevent dust and other particles from adhering to the working parts, and to drain the coolant generated during operation, the CNC machine tool in this solution has a wastewater tank at the bottom of the machine. However, particles from the external environment can enter the CNC machine tool from the wastewater tank. Therefore, to solve this problem, this solution also includes a connecting component 7. The connecting component 7 includes a moving block 701, a rotating rod 702, a rotating spring 703, and a sealing block 704. The sealing block 704 is slidably disposed at the bottom of the machine and can be locked or released from the wastewater tank. In a sealed fit, the movable block 701 is horizontally slidably mounted on the bottom of the machine base. The middle end of the rotating rod 702 is rotatably hinged to the bottom of the machine base. The rotating rod 702 is vertical in its normal state. The sealing block 704 is slidably mounted on one end of the rotating rod 702 along its axial direction. One end of the movable block 701 is slidably hinged to the other end of the rotating rod 702 along its axial direction. The two ends of the rotating spring 703 are respectively connected to one end of the rotating rod 702 and the bottom of the machine base. Furthermore, the top of the other end of the movable block 701 is inclined, perpendicular to the CNC machine... Looking from the front end of the bed towards the fixed frame 101, the vertical height of the other end of the moving block 701 gradually decreases, and the bottom surface of the moving block 701 is at the same horizontal level as the top surface of the locking block 605. Looking from top to bottom, one end of the driving block 604 can lock or release its abutment against the inclined end of the moving block 701. With this configuration, when the driving block 604 moves towards the locking block 605, the driving block 604 presses against the inclined end of the moving block 701, causing the moving block 701 to move away from the locking block 605, thereby driving the rotating rod 702, which cooperates with the moving block 701, to rotate. The rotating rod 702 changes from a vertical state to an inclined state, pushing the sealing block 704 that it cooperates with to slide, thereby releasing the sealing relationship between the sealing block 704 and the wastewater tank, so that the coolant generated by the CNC machine tool can be discharged from the wastewater tank when the CNC machine tool is working; when the CNC machine tool is not working, that is, the transport trolley 9 releases its cooperation relationship with the CNC machine tool, the drive block 604 returns to its original position, and then the rotating rod 702 returns to its original position under the action of the rotating spring 703, thereby driving the sealing block 704 and the moving block 701 to return to their original positions, and the sealing block 704 re-seales with the wastewater tank.

[0091] In summary, this utility model provides a positioning and clamping device for CNC machines. The carrier component makes the processing tray contact or detach from the support component, and then the pressing component presses the processing tray onto the support component for support and fixation. This facilitates the removal and insertion of the workpiece into and out of the CNC equipment, as well as the support and fixation of the processing tray and the stability of the processing tray.
