Technical Field

[0001] This utility model relates to the field of machine tool equipment technology, and in particular to a digital display instrument for machine tools with anti-collision function. Background Technology

[0002] In the field of machine tool technology, digital displays are key display and control components, and the protection of the buttons on their controllers is of paramount importance. To prevent accidental button presses from causing abnormal machine tool operation or even collisions, reliable protective devices are needed. The protective components designed in this invention, through the use of suction cups, protective shells, and other structural elements, provide a new approach to solving this problem.

[0003] In existing machine tool digital display protection technologies, protective covers are often attached using adhesive tape to protect the controller buttons. Operators need to cut the tape to the appropriate size and then stick the protective cover to the surface of the controller to isolate the buttons from the outside environment, thus preventing accidental activation.

[0004] In existing technologies, applying adhesive tape is cumbersome, time-consuming, and labor-intensive, and misalignment is prone to occur during application, affecting the protective effect. More seriously, adhesive residue remains on the controller surface after the tape is removed, making cleaning difficult. This not only affects the cleanliness of the equipment but also allows the residue to attract dust and other impurities, further impacting normal operation and increasing maintenance costs. Therefore, this paper proposes a digital display instrument for machine tools with anti-collision functionality to address these problems. Utility Model Content

[0007] The controller is equipped with a protective assembly, which includes a suction cup. The back of the suction cup contacts the front of the controller. A protective shell is fixedly connected to the front of the suction cup. The back of the protective shell is connected to the front of the suction cup. A piston is elastically connected to the inner wall of the protective shell via a spring A. The outer wall of the piston is in sealed contact with the inner wall of the protective shell.

A pressure plate is fixedly connected to one end of the movable rod, and an inclined block is fixedly connected to the other end of the movable rod. The inclined surface of the inclined block contacts the inclined surfaces on both sides of the piston. An unlocking assembly is provided on the protective shell.

[0008] As a further description of the above technical solution: the unlocking component includes an extension shell B, which is fixedly connected to both sides of the protective shell. The piston has slots on both sides. The extension shell B is fixedly connected to both sides of the protective shell. A pull rod is movably connected through the outer side of the extension shell B. An inclined block is elastically connected to the inner wall of the extension shell B through a spring B. One end of the pull rod is fixedly connected to the side of the inclined block, and the other end of the pull rod is fixedly connected to a button. The side of the inclined block abuts against the inner wall of the slot.

[0009] As a further description of the above technical solution: one end of the spring A is fixedly connected to the inner wall of the protective shell, and the other end of the spring A is fixedly connected to the front of the piston.

[0014] As a further description of the above technical solution: mounting plates are fixedly connected to both sides of the controller.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, the protective components are designed so that the suction cup can achieve a tight fit with the controller through atmospheric pressure, avoiding the use of traditional methods such as adhesive tape. This prevents residual glue or tape from affecting the cleanliness of the equipment. The protective shell completely covers the button to form a physical protective barrier, effectively preventing accidental touch.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a digital display instrument for machine tools with anti-collision function, including a digital display instrument 3. The digital display instrument 3 is used to display various parameters of the machine tool in real time, such as coordinate position and processing progress, so that the operator can intuitively understand the working status of the machine tool. A controller 1 is fixedly connected to the bottom of the digital display instrument 3. The controller 1 is the core input component for machine tool operation commands. Buttons are provided on the front. By operating these buttons, the operating parameters and working modes of the machine tool can be set and adjusted. A dustproof plate 4 is hinged to the front of the digital display instrument 3 by a pin. The dustproof plate 4 can rotate around the pin and can be closed when the digital display instrument 3 is not in use, protecting the display screen of the digital display instrument 3 from dust. To prevent dust, debris, and other contaminants, the front of the dustproof plate 4 is fitted with glass 5. The glass 5 ensures that the operator can clearly observe the display content of the digital display instrument 3 even when the dustproof plate 4 is closed, without affecting parameter viewing. The back of the dustproof plate 4 is magnetically connected to the front of the digital display instrument 3. This connection method facilitates the opening and closing of the dustproof plate 4, and it can fit tightly when closed, providing good dust protection. Mounting plates 2 are fixedly connected to both sides of the controller 1. The mounting plates 2 are used to fix the digital display instrument 3 in a suitable position on the machine tool. The front of the mounting plate 2 has threaded grooves, which facilitates a secure connection with the machine tool using bolts, ensuring that the digital display instrument 3 remains stable and does not shake during machine tool operation.

[0026] Reference Figure 1 - Figure 3The controller 1 is equipped with a protective component, including a suction cup 6. After installation, the suction cup 6 fits tightly against the front of the controller 1, using atmospheric pressure to fix the protective shell 7 onto the controller 1, thus preventing accidental button presses. The back of the suction cup 6 contacts the front of the controller 1, and the protective shell 7 is fixedly connected to the front of the suction cup 6. The protective shell 7 completely covers the buttons of the controller 1, forming a physical protective barrier to prevent accidental button presses from external factors. The front of the protective shell 7 has an exhaust port 8, which is used to vent air when the piston 11 moves. Excess gas inside the protective shell 7 is discharged, allowing the suction cup 6 to better adhere to the controller 1. The back of the protective shell 7 is connected to the front of the suction cup 6, ensuring that the air pressure inside the protective shell 7 and the suction cup 6 is consistent, which facilitates the adsorption function. The inner wall of the protective shell 7 is elastically connected to the piston 11 through the spring A10. The spring A10 provides elastic restoring force for the movement of the piston 11, so that the piston 11 can rebound and reset after the limit is released. One end of the spring A10 is fixedly connected to the inner wall of the protective shell 7, and the other end of the spring A10 is fixedly connected to the front of the piston 11.

[0027] Reference Figure 3 The outer wall of piston 11 is in sealed contact with the inner wall of protective shell 7 to ensure that the gas inside protective shell 7 does not leak and to guarantee the adsorption effect. Sloping surfaces are provided on both sides of piston 11, which cooperate with the sloping surfaces of inclined block 15 to realize the movement and limiting of piston 11. Extension shells A12 are fixedly connected to both sides of protective shell 7. Extension shells A12 provide installation space and moving tracks for movable rod 13 and inclined block 15, ensuring the stability of the movement of movable rod 13 and inclined block 15. Movable rod 13 is movably connected through the outer side of the extension shell. The pressure plate 14 is used to transmit the force of the pressure rod 14 and drive the inclined block 15 to move. One end of the movable rod 13 is fixedly connected to the pressure plate 14. The pressure plate 14 facilitates the operator to apply external force. The movement of the piston 11 is controlled by the movable rod 13 and the inclined block 15. The other end of the movable rod 13 is fixedly connected to the inclined block 15. The inclined block 15 pushes the piston 11 to move by interacting with the inclined surface of the piston 11, and limits the piston 11 after it moves to the position. The inclined surface of the inclined block 15 contacts the inclined surfaces on both sides of the piston 11. The protective shell 7 is provided with an unlocking component.

[0028] Reference Figure 2 , Figure 4The unlocking assembly includes an extension shell B16, which provides structural support for the unlocking operation of the digital display 3 and provides installation space for the pull rod 18, the wedge block 15, and the spring B19. The extension shell B16 is fixedly connected to both sides of the protective shell 7. The piston 11 has slots on both sides, which are used to cooperate with the wedge block 15 to limit and fix the piston 11, ensuring the stability of the protective shell 7 after installation. The extension shell B16 is fixedly connected to both sides of the protective shell 7. The pull rod 18 is movably connected through the outer side of the extension shell B16. The pull rod 18 is used to pull the wedge block 15 during unlocking, so that the wedge block 15 is separated from the slot of the piston 11. The inner wall of the extension shell B16 is elastically connected to the wedge block 15 through the spring B19. The spring B19 provides a restoring force for the wedge block 15, and can maintain the contact state with the slot of the piston 11 when the pull rod 18 is not operated, ensuring the stability of the protective shell 7 after installation.

[0029] Reference Figure 4 One end of spring B19 is fixedly connected to the inner wall of extension shell B16, and the other end of spring B19 is fixedly connected to the side of inclined block 15. One end of pull rod 18 is fixedly connected to the side of inclined block 15, and the other end of pull rod 18 is fixedly connected to a button. The button allows the operator to apply force to pull pull rod 18 to perform the unlocking operation. The side of inclined block 15 abuts against the inner wall of the slot. Slider 9 is fixedly connected to both the front and back of inclined block 15. Slider 9 cooperates with the slide groove 17 on the inner wall of extension shell B16 to provide guidance for the movement of inclined block 15 and ensure the smoothness and accuracy of the movement of inclined block 15. The inner wall of extension shell B16 has a slide groove 17, and the outer wall of slider 9 is slidably connected to the inner wall of slide groove 17.

[0030] Working Principle: When using the digital display instrument 3 with anti-collision function on this machine tool, first install the protective components. Accurately cover the button area of ​​the controller 1 with the suction cup 6, ensuring that the back of the suction cup 6 is in close contact with the smoothed front of the controller 1. At this time, simultaneously pinch the pressure plates 14 on both sides of the protective shell 7. The pressure plates 14 drive the inclined block 15 to move inward through the movable rod 13. The inclined surface of the inclined block 15 interacts with the inclined surfaces on both sides of the piston 11, causing the piston 11 to move away from the suction cup 6 on the inner wall of the protective shell 7. During the movement of the piston 11, the piston 11 compresses the spring A10, and at the same time, it expels excess gas inside the protective shell 7. As the piston 11 continues to move, the air pressure inside the protective shell 7 decreases, and the suction cup 6 is firmly attached to the front of the controller 1 under the action of external atmospheric pressure, thereby protecting the buttons on the controller 1 and effectively preventing accidental operation. During the movement of the piston 11, the piston 11 squeezes the inclined surface of the inclined block 15, causing the two inclined blocks 15 to overcome the elastic force of the spring B19 and move away from each other until the two inclined blocks 15 are completely inserted into the slots opened on both sides of the piston 11. At this time, the inclined blocks 15 are tightly abutted against the inner wall of the slot. Under the action of the elastic force of the spring B19, the piston 11 is limited and fixed, ensuring that the suction cup 6 is stably attached to the controller 1 and preventing the protective shell 7 from accidentally falling off.

[0031] When it is necessary to remove the protective shell 7 and operate the button of the controller 1, the unlocking component is used to pull the levers 18 on both sides of the protective shell 7. The levers 18 drive the inclined block 15 to move outward against the elastic force of the spring B19, so that the inclined block 15 separates from the slot opened by the piston 11. After the inclined block 15 releases its limit on the piston 11, the compressed spring A10 releases its elastic potential energy and pushes the piston 11 to rebound towards the suction cup 6 on the inner wall of the protective shell 7. The rebound of the piston 11 causes the air pressure inside the protective shell 7 to gradually recover, and the suction force between the suction cup 6 and the controller 1 disappears. At this time, the protective shell 7 can be easily removed and the button of the controller 1 can be operated normally. After the operation is completed, the protective shell 7 is reinstalled on the controller 1 according to the above installation steps to continue to protect the button.

[0032] In addition, the dustproof plate 4 hinged to the front of the digital display 3 can be closed by magnetic connection between the dustproof plate 4 and the front of the digital display 3 when the digital display 3 is not in use. The glass 5 facilitates observation of the display content of the digital display 3 and also serves as a dustproof function to protect the display screen of the digital display 3. The threaded grooves on the mounting plates 2 on both sides of the controller 1 make it easy to fix the digital display 3 in a suitable position on the machine tool with bolts, ensuring the stability of the digital display 3 during machine tool operation.
