[0002] In existing technologies, CNC machining centers, as highly automated numerical control machine tools, use computer programs to control the movement of cutting tools, enabling precise and complex machining of workpieces. During the machining process of this type of equipment, operators typically need to frequently perform workpiece loading and unloading operations.

[0003] However, in most traditional CNC machining centers, the worktable or fixture is usually fixed inside the machine tool's protective enclosure. During loading and unloading, operators often have to extend their arms or even their upper bodies into the relatively small and complex machining chamber. In this process, operators approach the machine tool spindle, cutting tools, or other moving parts, posing a high risk of bumps or scratches, resulting in poor safety during loading and unloading operations.

[0004] Therefore, it is necessary to improve CNC equipment to enhance the convenience and safety of loading and unloading operations and reduce potential safety accidents. Utility Model Content

[0005] Therefore, it is necessary to provide a CNC machining device that facilitates loading and unloading, so as to move the workpiece smoothly out of the machining area during loading and unloading, avoid safety accidents such as bumps and scratches that may occur in the confined space, and thus improve the safety of loading and unloading operations.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A CNC machining device for easy loading includes a machining center and a base. The base is installed inside the machining center. The base has a guide structure, which includes a first guide rail and a first limiting groove. Two first guide rails are fixedly connected to the top of the base. A slide block is slidably connected to the first guide rail. A first limiting groove is provided on the top side of the first guide rail. A first slider is fixedly connected to the slide block, extending into the interior of the first limiting groove.

[0008] Optionally, in one embodiment of the present invention, the limiting structure includes a connecting block and a handle, and two connecting blocks are fixedly connected to the bottom end of the saddle plate, with the same handle slidably connected to the two connecting blocks.

[0009] Optionally, in one embodiment of the present invention, a spring is sleeved on the outside of the handle, and a stop block is fixedly connected to both ends of the handle. One end of the spring abuts against the stop block, and the other end of the spring abuts against the connecting block.

[0010] Optionally, in one embodiment of the present invention, two guide blocks are fixedly connected to the bottom end of the saddle plate, a locking block is slidably connected to the guide block, and a guide groove is provided on the locking block. Two guide shafts are fixedly connected to the handle, the guide shafts extend into the interior of the adjacent guide grooves and are slidably connected to the locking block, and two locking slots are provided at the top end of the base, and the bottom end of the locking block engages with the adjacent locking slot.

[0011] Optionally, in one embodiment of the present invention, the cross-section of the bottom end of the card block is trapezoidal, and the cross-section of the card slot is trapezoidal.

[0021] To facilitate loading and unloading, ensure production safety, and prevent accidents, a CNC machining device for easy loading and unloading was designed. The specific solution is as follows: Example 1

[0022] like Figure 1-6 As shown, a CNC machining device for easy loading includes a machining center 1 and a base 2. The base 2 is installed inside the machining center 1. The base 2 is provided with a guide structure 3, which includes a first guide rail 301 and a first limiting groove 302. Two first guide rails 301 are fixedly connected to the top of the base 2. A slide block 304 is slidably connected to the first guide rail 301. The top side of the first guide rail 301 is provided with the first limiting groove 302. A first slider 303 is fixedly connected to the slide block 304 and extends into the first limiting groove 302. A second guide rail 307 is slidably connected to the slide block 304 and is provided with a second limiting groove 306. A second slider 305 is fixedly connected to the slide block 304 and extends into the second limiting groove 306. The top ends of the two second guide rails 307 are fixedly connected to the same saddle plate 4, which is provided with a limiting structure 6.

[0023] The two first guide rails 301 are symmetrically distributed about the middle of the base 2, and the two second guide rails 307 are symmetrically distributed about the middle of the saddle plate 4. Therefore, the movement of the saddle plate 4 can be guided by the sliding block 304 sliding between the first guide rail 301 and the second guide rail 307 at the same time.

[0024] The limiting structure 6 includes a connecting block 601 and a handle 602. Two connecting blocks 601 are fixedly connected to the bottom of the saddle plate 4. The two connecting blocks 601 slide between the handle 602 at the same time, which can guide the movement of the handle 602. The same handle 602 is slidably connected to the two connecting blocks 601. The saddle plate 4 can be moved conveniently by holding the handle 602.

[0025] A spring 603 is sleeved on the outside of the handle 602. A stop block 604 is fixedly connected to both ends of the handle 602. Therefore, the stop block 604 can block and limit the spring 603. One end of the spring 603 abuts against the stop block 604, and the other end of the spring 603 abuts against the connecting block 601. The spring 603 can keep the locking block 607 engaged with the locking groove 609.

[0026] Two guide blocks 608 are fixedly connected to the bottom of the saddle plate 4. The guide blocks 608 can guide the movement of the locking block 607. The locking block 607 is slidably connected to the guide block 608. The locking block 607 is provided with a guide groove 606. Two guide shafts 605 are fixedly connected to the handle 602. The guide shafts 605 extend into the interior of the adjacent guide grooves 606 and are slidably connected to the locking block 607. The top of the base 2 is provided with two locking slots 609. The bottom of the locking block 607 engages with the adjacent locking slots 609. Therefore, the saddle plate 4 can be limited to prevent it from moving during the processing of the workpiece.

[0027] The bottom of the locking block 607 has a trapezoidal cross-section, and the slot 609 has a trapezoidal cross-section, thus it can play a guiding role when the locking block 607 and the slot 609 are engaged.

[0028] The handle 602 has a C-shaped cross-section, which makes it easy to grip. The guide groove 606 has a certain angle with the direction of movement of the locking block 607, so that when the guide shaft 605 moves inside the guide groove 606, the locking block 607 can slide on the guide block 608.

[0029] The saddle plate 4 is provided with a fixing structure 5, which includes a connecting seat 501 and a sliding groove 502. The connecting seat 501 is installed on the top of the saddle plate 4, and the sliding groove 502 is provided on the connecting seat 501. The sliding groove 502 can guide the movement of the clamping plate 503. Two clamping plates 503 are slidably connected inside the sliding groove 502. A screw 504 is rotatably connected to the connecting seat 501. The screw 504 is threadedly connected to the two clamping plates 503, thus enabling the clamping and fixing of the workpiece.

[0030] The two threads of the screw 504 have opposite directions, so when the screw 504 rotates in one direction, the two clamps 503 can move in opposite directions. One end of the screw 504 is fixedly connected to a connector 505. The connector 505 has a hexagonal cross-section and can be used to insert a wrench into the connector 505 to facilitate the rotation of the screw 504.

[0031] The two clamping plates 503 are symmetrically distributed about the middle of the connecting seat 501, and the cross-section of the slide groove 502 is trapezoidal, thus enabling precise guidance of the clamping plates 503.

[0032] Working principle: When a workpiece is finished and needs to be removed, and the next workpiece is to be loaded, by pulling the handle 602, the two springs 603 retract simultaneously. The handle 602 drives the two guide shafts 605 to move. When the guide shafts 605 move inside the guide groove 606, the locking block 607 moves away from the locking groove 609. When the locking block 607 and the locking groove 609 are no longer engaged, the handle 602 is pulled again. The saddle plate 4 will drive the second guide rail 307 to slide on the two slide blocks 304 at the same time. At this time, the second slider 305 moves inside the second limiting groove 306. When one side of the second slider 305 abuts against the slide block 304, it will drive the slide block 304 to slide on the first guide rail 301. At this time, the first slider 303 moves inside the first limiting groove 302, which can increase the range of motion of the saddle plate 4, so that the saddle plate 4 can move from the inside of the machining center 1 to the outside of the machining center 1.

[0033] After the saddle plate 4 has moved completely to the outside of the machining center 1, a wrench can be inserted into the connector 505, and then the screw 504 can be rotated to move the two clamping plates 503 away from each other. The machined workpiece can then be taken out between the two clamping plates 503. The workpiece to be processed is then placed between the two clamping plates 503 and fixed. Then the saddle plate 4 is pushed into the machining center 1. After the saddle plate 4 is reset, under the action of the spring 603, the locking block 607 will engage with the locking groove 609, preventing the saddle plate 4 from moving. This completes the loading and unloading of the workpiece. During the loading and unloading process, there is no need to put one's body into the machining center 1, reducing the risk of collision and improving the safety of the loading and unloading operation.

[0034] The CNC machining device of this solution facilitates loading and unloading. By pulling the handle 602, the saddle plate 4 can be moved outside the machining center 1. The operator does not need to put any part of his body into the machine tool to carry out loading and unloading operations, avoiding the risk of collision, pinching or scratching of the operator with the internal parts of the machine tool, sharp machining chips and the machine tool structure.

[0035] When the saddle plate 4 carries the processed workpiece out, the operator can safely and more easily unload the workpiece and install the new blank workpiece outside the machine tool. During this process, the main body of the machine tool can be prepared, reducing the idle time of the machine tool waiting for manual loading and unloading.

[0036] The first guide rail 301 and the slide, and the second guide rail 307 and the saddle plate 4, expand the movable range of the saddle plate 4, ensuring that it can be fully moved out of the processing area, and also ensuring the stability of the saddle plate 4 during movement, preventing the workpiece from vibrating or shifting during movement.

[0037] By pulling the C-shaped handle 602, the compression of the spring 603 and the movement of the guide shaft 605 within the guide groove 606 cause the locking block 607 to disengage from the slot 609 of the base 2, thus unlocking the saddle plate 4. Releasing the handle 602 or pushing it back causes the spring 603 to reset and automatically drive the locking block 607 back into the slot 609, completing the locking process. The operation is simple.

[0038] The workpiece is clamped by driving two symmetrical clamping plates 503 with screws having opposite threads. The clamping force is uniform, which helps to ensure machining accuracy.

[0039] The device has a relatively independent structure, making it easy to adapt and install inside different CNC machining centers, and the modification cost is low. Example 2

[0040] In this embodiment, the structure of the device is basically the same as that of Embodiment 1. The difference is that a combination structure of lead screw and slider is installed on the base 2. The slider is fixedly connected to the bottom of the saddle plate 4, and the slider is slidably connected to the lead screw. Both ends of the lead screw are screwed onto the base 2. The outer end of the lead screw is connected to a servo motor so as to push the saddle plate 4 to slide more easily and with less effort, and to make the position of the saddle plate 4 more accurate.

[0041] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
