DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0023] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0024] In one embodiment, see Figure 1 and Figure 2A protective device for mechanical processing equipment includes a processing platform 2, a support frame 1 is fixed on the top of the processing platform 2, a support plate 6 is provided between the support frame 1 and the platform, the support plate 6 is connected to the top of the support frame 1 through a telescopic rod 8, and a processing tool 7 is installed on the support plate 6. A symmetrically distributed protective cover 5 is slidably connected to the surface of the processing platform 2, and the protective cover 5 is connected to a driving mechanism, which is used to drive the protective cover 5 to move relative to each other. The surface of the processing platform 2 is provided with symmetrically distributed chip removal ports 10, and the inner sides of the protective covers 5 are provided with symmetrically distributed chip accumulation plates 9, which are rotatably connected to the protective covers 5 through a swinging mechanism. When the two protective covers 5 are far away from each other, the swinging mechanism is used to drive the chip accumulation plate 9 to swing, so that the iron chips on the surface of the chip accumulation plate 9 enter the chip removal port 10.

[0025] In this embodiment, when the protective device is in use, the workpiece is fixed on the surface of the processing platform 2 by the clamping mechanism, the support plate 6 is driven to move downward by the telescopic rod 8, the support plate 6 drives the processing tool 7 to move downward, and the processing tool 7 processes the workpiece, wherein the processing tool 7 can be a grinding tool, a drilling tool, a polishing tool, etc., while the support plate 6 moves downward, the two protective covers 5 are driven to approach each other by the driving mechanism until the two protective covers 5 fit each other, and the setting of the protective cover 5 can effectively prevent the iron chips generated during the workpiece processing from causing damage to the staff, which plays a protective role for the staff, and the inner side of the protective cover 5 is provided with symmetrically distributed chip accumulation Plate 9, when the two protective covers 5 are fitted, the chip accumulation plates 9 are in a horizontal state, and the iron chips generated during the workpiece processing will first hit the inner wall of the protective cover 5, and finally fall on the surface of the chip accumulation plate 9. The setting of the chip accumulation plate 9 can collect the iron chips to a certain extent. When the workpiece processing is completed, the support plate 6 drives the processing tool 7 to move upward, and the protective covers 5 move away from each other. When the protective covers 5 move away from the maximum distance, the swing mechanism drives the chip accumulation plate 9 to swing, so that the end of the chip accumulation plate 9 close to the chip discharge port 10 tilts downward. At this time, the iron chips on the surface of the chip accumulation plate 9 fall into the chip discharge port 10 along the chip accumulation plate 9, which is convenient for the staff to centrally process the iron chips generated during the workpiece processing.

[0026] See also Figure 3 The swing mechanism includes a rotating rod 32 fixed on the side wall of the chip accumulation plate 9, the rotating rod 32 passes through the side wall of the protective cover 5 and is rotatably connected to the side wall of the protective cover 5, a rotating column 34 is fixed to the end of the rotating rod 32, and the rotating column 34 is connected to the outer wall of the protective cover 5 through a torsion spring 33, and the side walls of the chip accumulation plate 9 are fixed with first magnets 31, and the magnetic properties of the first magnets 31 on the chip accumulation plates 9 connected to the two protective covers 5 are opposite;

[0027] When the two protective covers 5 are close to each other, they also drive the chip accumulation plates 9 to be close to each other. When the two protective covers 5 are in contact with each other, the first magnets 31 on the chip accumulation plates 9 connected to the two protective covers 5 attract each other, so that the chip accumulation plates 9 are in a horizontal state, thereby collecting iron chips in the workpiece processing process. When the workpiece processing is completed, the support plate 6 drives the processing tool 7 to move upward, and the protective covers 5 move away from each other. When the protective covers 5 move away, they drive the first magnets 31 on the chip accumulation plates 9 away from each other. The first magnets 31 no longer attract each other, and the chip accumulation plates 9 automatically reset under the action of the torsion spring 33, so that the end of the chip accumulation plate 9 close to the chip discharge port 10 tilts downward, so that the iron chips on the surface of the chip accumulation plate 9 enter the chip discharge port 10 along the chip accumulation plate 9, which is convenient for the staff to centrally process the iron chips.

[0028] See also Figure 3 A slide plate 39 is fixed on the outer wall of the protective cover 5, a pin rod 36 is passed through the inside of the slide plate 39, the pin rod 36 is slidably connected to the slide plate 39, a baffle plate 37 is fixed to the outside of the pin rod 36, the baffle plate 37 is connected to the slide plate 39 through a first elastic component 38, a pin groove 35 adapted to the pin rod 36 is provided on the side wall of the rotating column 34, a second magnet 310 is fixed to the end of the pin rod 36, a third magnet 311 is fixed to the top of the processing platform 2, and the second magnet 310 and the third magnet 311 have opposite magnetic properties;

[0029] When the chip plate 9 rotates, the rotating column 34 is driven to rotate through the rotating rod 32. When the chip plate 9 is in a horizontal state, the pin groove 35 on the side wall of the rotating column 34 is aligned with the pin rod 36. The pin rod 36 automatically enters the pin groove 35 under the action of the first elastic component 38 and the baffle 37. The first elastic component 38 can be a spring. The pin rod 36 fixes the rotating column 34 through the pin groove 35, and then fixes the chip plate 9, ensuring the stability of the chip plate 9. When the workpiece is processed, the protective cover 5 drives the chip plates 9 away from each other. At this time, even if the mutual attraction of the first magnet 31 is lost, the chip plate 9 is also in a horizontal state under the positioning of the pin rod 36. state, thereby preventing the chip accumulation plate 9 from tilting and causing iron chips to fall on the surface of the processing platform 2 when the protective cover 5 moves away from each other. When the protective cover 5 is moved away to the maximum extent, the second magnet 310 just moves above the third magnet 311. Under the attraction of the third magnet 311, the second magnet 310 drives the pin rod 36 to move downward, thereby moving the pin rod 36 to the outside of the pin groove 35. Without the fixation of the pin rod 36, the chip accumulation plate 9 swings rapidly under the action of the torsion spring 33, and then throws the iron chips on its surface into the chip discharge port 10, which is convenient for the staff to centrally process the iron chips. At the same time, it can also avoid the phenomenon that the iron chips are accumulated on the surface of the chip accumulation plate 9 due to friction and cannot slide downward.

[0030] See also Figure 2 and Figure 5 The driving mechanism includes a mounting plate 41 fixed to the bottom of the support plate 6 and symmetrically distributed, and fourth magnets 42 are fixed on the mounting plates 41. A fifth magnet 43 is fixed on the side wall of the protective cover 5. The fourth magnet 42 has the same magnetic properties as the fifth magnet 43. A fixing component and a reset component are provided on the top of the processing platform 2. When the two protective covers 5 are attached, the fixing component is used to fix the protective covers 5. When the fixing component no longer fixes the protective covers 5, the reset component is used to reset the protective covers 5.

[0031] When processing the workpiece, the support plate 6 drives the fourth magnet 42 to move downward through the mounting plate 41. When the fourth magnet 42 moves to the side of the fifth magnet 43, the fourth magnet 42 and the fifth magnet 43 repel each other, thereby pushing the protective cover 5 so that the protective covers 5 are close to each other. When the protective covers 5 fit each other, the fixing assembly will automatically fix the protective covers 5, thereby ensuring the stability of the protective covers 5. At this time, the support plate 6 will not cause the protective covers 5 to move away from each other when moving up and down, thereby facilitating the processing of the workpiece by the processing tool 7. When the workpiece is processed, the fixing assembly no longer fixes the protective covers 5, and the protective covers 5 move away from each other under the action of the resetting assembly.

[0032] See also Figure 2 The reset assembly includes a guide plate 44 fixed on the top of the processing platform 2, and the guide plate 44 is penetrated by symmetrically distributed guide rods 45, and the ends of the guide rods 45 are fixedly connected to the protective cover 5. The guide rod 45 is provided with a second elastic component 46 on the outside, and the two ends of the second elastic component 46 are respectively fixedly connected to the guide plate 44 and the side wall of the protective cover 5;

[0033] When the workpiece is processed and the fixing assembly no longer fixes the protective cover 5, the protective cover 5 automatically resets under the action of the second elastic component 46, so as to move away from each other, wherein the second elastic component 46 can be a spring, and the guide plate 44 can limit the protective cover 5 through the guide rod 45, thereby effectively improving the stability of the protective cover 5 when moving.

[0034] See also Figure 2 and Figure 4 The fixing assembly includes a slider 47 fixedly connected to the protective cover 5, the slider 47 is slidably connected to the processing platform 2, a limiting groove 48 is provided inside the slider 47, a trapezoidal block 49 is passed through the top of the processing platform 2, a first guide column 410 is fixed to the bottom of the processing platform 2, the lower end of the trapezoidal block 49 extends into the first guide column 410 and is slidably connected to the inner wall of the first guide column 410 through a third elastic component 411, and the trapezoidal block 49 is connected to a traction component, which is used to pull the trapezoidal block 49 to the outside of the limiting groove 48;

[0035] When the support plate 6 moves downward, the mutual repulsion between the fourth magnet 42 and the fifth magnet 43 pushes the two protective covers 5 closer to each other. When the protective cover 5 moves to a certain position, the bottom of the protective cover 5 squeezes the inclined surface of the trapezoidal block 49, so that the trapezoidal block 49 enters the first guide column 410. When the protective covers 5 are fitted to each other, the trapezoidal block 49 is aligned with the limiting groove 48 inside the slider 47. The trapezoidal block 49 automatically enters the limiting groove 48 under the action of the third elastic component 411. The third elastic component 411 can be a spring, which can fix the slider 47 through the trapezoidal block 49, and then fix the protective cover 5, thereby ensuring the stability of the protective cover 5.

[0036] See also Figure 2 and Figure 4 The traction component includes a traction rope 412 fixedly connected to the trapezoidal block 49, a second guide column 413 is fixed to the bottom of the processing platform 2, and the first guide column 410 and the second guide column 413 are both penetrated by a guide groove for guiding the traction rope 412, and the traction rope 412 passes through the guide groove and is fixedly connected to the support plate 6;

[0037] When the workpiece is processed, the telescopic rod 8 drives the support plate 6 to move upward. When the support plate 6 is about to rise to the highest position, under the guidance of the first guide column 410 and the second guide column 413, the support plate 6 pulls the trapezoidal block 49 through the traction rope 412 until the traction rope 412 pulls the trapezoidal block 49 to the outside of the limiting groove 48, and the trapezoidal block 49 loses its limit. The protective cover 5 is automatically reset under the action of the reset component.

[0038] Working principle: When the protective device is in use, the workpiece is fixed on the surface of the processing platform 2 through the clamping mechanism, and the support plate 6 is driven to move downward by the telescopic rod 8, and the support plate 6 drives the processing tool 7 to move downward, and the processing tool 7 processes the workpiece. While the support plate 6 moves downward, the fourth magnet 42 is driven downward by the mounting plate 41. When the fourth magnet 42 moves to the side of the fifth magnet 43, the fourth magnet 42 and the fifth magnet 43 repel each other, thereby pushing the protective cover 5 so that the protective covers 5 are close to each other. When the protective covers 5 are fitted together, the trapezoidal block 49 automatically enters the limiting groove 48, and the trapezoidal block 49 can play a fixing role on the slider 47, and then plays a fixing role on the protective cover 5, ensuring the stability of the protective cover 5, and when the protective cover 5 is fitted together, the first magnets 31 on the chip accumulation plate 9 connected to the two protective covers 5 attract each other, so that the chip accumulation plate 9 is in the water. When the workpiece is processed, the support plate 6 drives the processing tool 7 to move upward. When the support plate 6 is about to rise to the highest position, under the guidance of the first guide column 410 and the second guide column 413, the support plate 6 pulls the trapezoidal block 49 through the traction rope 412 until the traction rope 412 pulls the trapezoidal block 49 to the outside of the limiting groove 48. The limit of the trapezoidal block 49 is lost, and the protective cover 5 is automatically reset. When the protective cover 5 is away from the maximum extent, the second magnet 310 just moves to the top of the third magnet 311. At this time, under the attraction of the third magnet 311, the second magnet 310 drives the pin rod 36 to move downward, thereby moving the pin rod 36 to the outside of the pin groove 35. The fixation of the pin rod 36 is lost, and the chip accumulation plate 9 swings rapidly under the action of the torsion spring 33, and then the iron chips on its surface are thrown into the chip discharge port 10, which is convenient for the staff to centrally process the iron chips.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
