Description

Technical Field

[0001] This invention belongs to the field of machine tool protective covers, specifically a quick-assembly and disassembly structure for machine tool protective covers. Background Technology

[0002] Machine tool guards are important safety accessories installed on various mechanical equipment, especially metal cutting machine tools. Their main function is to prevent injury to the human body from debris, chips, coolant splashes, etc. generated during processing. They can also prevent dust and foreign objects from entering the machine tool, protect the precision parts of the machine tool from damage, extend the service life of the machine tool, and improve the safety and cleanliness of the working environment.

[0003] With the rapid development of intelligent manufacturing, more requirements are being placed on the flexibility of production lines. In order to facilitate line changeover, the chip guards of machine tools need to be frequently replaced. The existing machine tool protective covers take up a lot of space after being disassembled, and it is difficult to fold and stack them. In addition, the installation and removal of machine tool protective covers require a lot of tools and bolts, making the assembly process cumbersome and the disassembly process complicated. Since machine tools often need to be inspected and maintained, the efficiency of disassembling and installing protective covers is low, which to some extent affects the flexibility of machine tool production line changeover and the efficiency of daily inspection and maintenance.

[0004] To address the problems raised in the background art, those skilled in the art have proposed a quick-release and disassembly structure for machine tool protective covers. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention provides a quick-assembly and disassembly structure for machine tool protective covers. This solves the problems of difficulty in assembling and disassembling protective covers on flexible production lines, the large space occupied by the machine tool protective covers after disassembly, the difficulty in folding and stacking the protective covers, the need for numerous tools and bolts for assembly and disassembly of the machine tool protective covers, the cumbersome assembly process, and the complex disassembly process.

[0006] A quick-assembly and disassembly structure for a machine tool protective cover includes a spindle frame, a first extension frame, and a second extension frame; a telescopic component and a folding protective layer are installed between the spindle frame and the first and second extension frames.

[0007] The telescopic assembly includes several storage slots formed on the inner wall of the shaft frame, a slide block that slides in the storage slots, a first connecting seat fixed to the side wall of the first extension frame, a second connecting seat fixed to the side wall of the second extension frame, a first connecting rod hinged to the inner wall of the first connecting seat, a second connecting rod hinged to the periphery of the second connecting seat, and a folding slot formed on the inner wall of the first connecting rod; the second connecting rod is hinged to the first connecting rod, and the first connecting rod is hinged to the slide block.

[0008] The above technical solution allows the first and second connecting rods to be quickly stored in the storage slot simultaneously, enabling the rapid folding of the first and second extension racks and effectively reducing their size for easy storage or transportation.

[0009] Preferably, the size of the second connecting rod is adapted to the folding groove, and the second connecting rod is located inside the folding groove after folding.

[0010] Preferably, the storage slot is an "L" shaped slot structure, and a winding slot is provided at the axis of symmetry of the storage slot, and a winding assembly is installed in the winding slot.

[0011] Preferably, the winding assembly includes a rotating rod rotatably connected to the axis of symmetry of the winding groove, a winding wheel installed around the rotating rod, a pull rope connected between the winding wheel and the slide block, and a knob fixed to one end of the rotating rod.

[0012] With the above technical solution, when it is necessary to retract the first extension frame and the second extension frame, rotating the knob will drive the winding wheel to simultaneously wind up the two sets of pull ropes. The two sets of pull ropes will simultaneously pull the slide block to the other end of the storage slot. When the slide block moves, it will pull the first connecting rod and pull the first connecting rod into the storage slot. Since the storage slot is wider than the first connecting rod, the first connecting rod and the first connecting rod can be completely folded into the storage slot. Furthermore, when the first connecting rod is retracted into the storage slot, the second connecting rod is retracted into the folding slot, thereby retracting the first connecting rod and the second connecting rod into the storage slot at the same time, realizing the rapid retraction of the first extension frame and the second extension frame.

[0013] Preferably, the storage slot has through-holes on both sides of the side wall, the slide base is fixedly connected to the limiting frame, the limiting frame is slidably engaged with the limiting slot, and the inner wall of the limiting frame is fixedly connected to the connecting shaft; the first connecting rod is hinged to the connecting shaft.

[0014] Preferably, a clamping assembly is fixedly connected to the bottom surface of the shaft frame; the clamping assembly includes two sets of base frames fixed to the bottom surface of the shaft frame, a screw rod rotatably connected to the side wall of the base frame, an electric actuator rotatably installed at one end of the screw rod, a clamping seat installed at the output end of the electric actuator rod, and a throttle handle installed at the other end of the screw rod; a limit block is slidably engaged between the electric actuator rod and the base frame.

[0015] Preferably, a card reader is mounted on the base frame, and the card reader is electrically connected to the electric push rod.

[0016] The above technical solution allows for the rapid installation of the protective cover on the machine tool surface. A card reader controls the operation of the electric actuator, which moves the clamping seat. Adjusting the position of the clamping seat facilitates the fixed installation on machine tools of different sizes and allows for quick unlocking of the clamping seat. When the equipment is not powered on, rotating the throttle moves the electric actuator and clamping seat together, enabling manual installation or unlocking of the clamping seat. Limit blocks ensure the electric actuator remains stable, preventing it from shifting.

[0017] Preferably, the folded protective layer is made of composite fiber material, such as carbon fiber or glass fiber.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. This invention, by setting up a telescopic component and a foldable protective layer, allows the first and second connecting rods to be simultaneously stored in the storage slot, achieving rapid folding of the first and second extension frames, effectively reducing the volume of the protective cover for easy storage or transportation; since the storage slot is symmetrically arranged about the corner of the spindle frame, multiple sets of connecting rods can be installed between the spindle frame and the extension frame at the same time. The design of multiple sets of connecting rods ensures that the protective cover has a good support effect after being stretched, and the multiple sets of connecting rods form the protective rods of the protective cover, which can effectively block fragments and chips generated during processing, thereby improving the protective capability of the protective cover.

[0020] 2. By setting up a winding component, the present invention can quickly and completely fold the first connecting seat and the first connecting rod into the storage slot, and facilitates the subsequent unfolding of the telescopic component.

[0021] 3. This invention, by setting up a clamping assembly, can quickly install the protective cover on the surface of the machine tool; by swiping a card at the card reader to control the operation of the electric actuator, the electric actuator drives the clamping seat to move, and by adjusting the position of the clamping seat, it is easy to fix and install on machine tools of different sizes, and at the same time, the clamping seat can be quickly unlocked; when the equipment is not powered on, by rotating the throttle, the electric actuator and the clamping seat are moved as a whole, so as to manually install or unlock the clamping seat.

[0030] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0031] Example 1: As shown in the attached document Figure 1 To be continued Figure 6 As shown: This invention provides a quick-assembly and disassembly structure for a machine tool protective cover, including a spindle frame 1, a first extension frame 2, and a second extension frame 3; a telescopic component and a foldable protective layer 19 are installed between the spindle frame 1 and the first extension frame 2 and the second extension frame 3; the foldable protective layer 19 is made of composite fiber material, such as carbon fiber or glass fiber. The composite fiber material has high strength and impact resistance, and can extend and retract in conjunction with the first extension frame 2 and the second extension frame 3 to provide good protective performance for the protective cover.

[0032] The telescopic assembly includes several storage slots 4 formed on the inner wall of the shaft frame 1, a slide block 7 sliding in the storage slots 4, a first connecting seat 5 fixed to the side wall of the first extension frame 2, a second connecting seat 8 fixed to the side wall of the second extension frame 3, a first connecting rod 6 hinged to the inner wall of the first connecting seat 5, a second connecting rod 9 hinged to the periphery of the second connecting seat 8, and a folding slot 601 formed on the inner wall of the first connecting rod 6; the size of the second connecting rod 9 is adapted to the folding slot 601, and the second connecting rod 9 is located in the folding slot 601 after folding; the second connecting rod 9 is hinged to the first connecting rod 6, and the first connecting rod 6 is hinged to the slide block 7;

[0033] By setting the first connecting seat 5, the first connecting rod 6 has a stable rotation function. By setting the second connecting seat 8, the second connecting rod 9 can rotate stably. By setting the folding groove 601, when the slide 7 rises, the slide 7 pulls the first connecting rod 6 and pulls the first connecting rod 6 into the storage groove 4. Since the storage groove 4 is wider than the first connecting seat 5, the first connecting seat 5 and the first connecting rod 6 can be completely folded into the storage groove 4. When the first connecting rod 6 is put into the storage groove 4, the second connecting rod 9 is put into the folding groove 601, so that the first connecting rod 6 and the second connecting rod 9 are put into the storage groove 4 at the same time. This realizes the rapid folding of the first extension frame 2 and the second extension frame 3, effectively reducing the volume of the protective cover and making the protective cover easy to store or transport.

[0034] Since the storage slot 4 is symmetrically arranged about the corner of the spindle frame 1, multiple sets of connecting rods can be installed between the spindle frame 1 and the extension frame at the same time. The design of multiple sets of connecting rods ensures that the protective cover has a good support effect after being stretched, and the multiple sets of connecting rods form the protective rods of the protective cover, which can effectively block the fragments and chips generated during the processing and improve the protective capability of the protective cover; the connecting rods located at the bottom and top of the spindle frame 1 and the extension frame can all be folded into the storage slot 4;

[0035] When the first extension rack 2 and the second extension rack 3 are quickly stored, the volume of the protective cover can be greatly reduced, making it easier to disassemble, store, or transport, thus improving portability.

[0036] Limiting grooves 401 penetrate the two side walls of the storage slot 4. A limiting frame 701 is fixedly connected to the bottom wall of the slide block 7. The limiting frame 701 slides with the limiting groove 401. A connecting shaft 702 is fixedly connected to the inner wall of the limiting frame 701. The first connecting rod 6 is hinged to the connecting shaft 702.

[0037] As can be seen from the above, by setting the limiting bracket 701 and the limiting groove 401, the slide 7 has a stable sliding function and prevents the slide 7 from falling out of the storage groove 4.

[0038] Example 2: As shown in the attached document Figure 2 To be continued Figure 4 As shown: This embodiment is basically the same as the previous embodiment, except that the storage slot 4 is an "L" shaped slot structure, and a winding slot 101 is provided at the axis of symmetry of the storage slot 4. A winding assembly is installed in the winding slot 101. The winding assembly includes a rotating rod 10 rotatably connected to the axis of symmetry of the winding slot 101, a winding wheel 11 installed around the rotating rod 10, a pull rope 13 connecting the winding wheel 11 and the slide block 7, and a knob 12 fixed to one end of the rotating rod 10.

[0039] As can be seen from the above, when the protective cover needs to be unfolded, turn the knob 12 to drive the rotating rod 10 to loosen the anti-pull rope 13. The two sets of pull ropes 13 unfold simultaneously. At this time, the two sets of slides 7 move towards the direction of unfolding the extension frame. During the sliding process of the slides 7, the first connecting rod 6 and the second connecting rod 9 are opened. When the first connecting rod 6 and the second connecting rod 9 are fully unfolded, the first extension frame 2 and the second extension frame 3 are unfolded, and the slides 7 are in a stable position due to gravity. When the first extension frame 2 and the second extension frame 3 are unfolded, the foldable protective layer 19 unfolds accordingly, thereby realizing the opening of the protective cover.

[0040] When it is necessary to retract the first extension frame 2 and the second extension frame 3, rotate the knob 12 to drive the winding wheel 11 to simultaneously wind up the two sets of pull ropes 13. The two sets of pull ropes 13 simultaneously pull the slide 7, pulling the slide 7 to the other end of the storage slot 4. When the slide 7 moves, the slide 7 pulls the first connecting rod 6 and pulls the first connecting rod 6 into the storage slot 4. Since the size of the storage slot 4 is wider than the first connecting seat 5, the first connecting seat 5 and the first connecting rod 6 can be completely folded into the storage slot 4. When the first connecting rod 6 is put into the storage slot 4, the second connecting rod 9 is put into the folding slot 601, so that the first connecting rod 6 and the second connecting rod 9 are put into the storage slot 4 at the same time, realizing the rapid retraction of the first extension frame 2 and the second extension frame 3.

[0041] Example 3: As shown in the attached document Figure 1 To be continued Figure 6 As shown: Based on Embodiment 1, a clamping assembly is fixedly connected to the bottom surface of the spindle frame 1; the clamping assembly includes two sets of base frames 14 fixed to the bottom surface of the spindle frame 1, a screw 18 rotatably connected to the side wall of the base frame 14, an electric push rod 15 rotatably installed at one end of the screw 18, a clamping seat 17 installed at the output end of the electric push rod 15, and a throttle 21 installed at the other end of the screw 18; a limit block 16 is slidably engaged between the electric push rod 15 and the base frame 14; a card reader 20 is installed on the upper surface of the base frame 14, and the card reader 20 is electrically connected to the electric push rod 15. The card reader 20 can effectively prevent the protective cover from being accidentally removed when the machine tool is moving.

[0042] As can be seen from the above, the protective cover can be quickly installed on the surface of the machine tool; by swiping a card at the card reader 20, the electric push rod 15 is controlled to work, and the electric push rod 15 drives the clamping seat 17 to move. By adjusting the position of the clamping seat 17, it is convenient to fix and install machine tools of different sizes, and the clamping seat 17 can be quickly unlocked; when the equipment is not powered on, by rotating the throttle 21, the electric push rod 15 and the clamping seat 17 are moved as a whole, so as to manually install or unlock the clamping seat 17; by setting the limit block 16, the electric push rod 15 is kept in a stable state to prevent the electric push rod 15 from deviating.
