Description

Technical Field

[0001] The present invention belongs to the technical field of machining, and specifically relates to a protective cover structure for a machining equipment and its working method. Background Art

[0002] During the machining operation, such as some drilling and grinding equipment, a large amount of debris will be generated during the production process. Therefore, it is necessary to protect these mechanical equipment to reduce the impact of debris splashing on the human body. The traditional protection mechanism is generally fixedly installed on the workbench in advance. During use, the workpiece is placed on the equipment for processing through the side door opened on one side of it. However, when facing a workpiece with a large size, since the position and angle of the protection mechanism cannot be adjusted according to the size of the workpiece, the use requirements cannot be met. In short, with the development of technology, the existing protection structure can no longer meet the production needs, and there is an urgent need to provide a protective cover structure for a machining equipment that can adjust the angle and height according to the size of the workpiece. Summary of the Invention

[0003] Aiming at the deficiencies of the existing technology, the purpose of the present invention is to provide a protective cover structure for a machining equipment and its working method, which can adjust the height as needed to effectively block the splashing of debris.

[0004] To achieve the above purpose, the present invention adopts the following technical solutions to be realized:

[0005] A protective cover structure for a machining equipment, including a base platform, a support rod is fixedly connected to the top of the base platform, and a top plate is fixedly connected to the top of the support rod.

[0006] The protective cover structures are provided on both sides of the top plate. The protective cover structure includes a protective cover and a cross plate. A rotating shaft is fixedly connected to the inner side of the cross plate. The two ends of the rotating shaft are rotatably connected to a first connecting plate, and the first connecting plate is fixedly connected to the side surface of the top plate. A nut is fixedly connected to the outer side of the cross plate.

[0007] A vertical groove is opened at the center position inside the protective cover. A lead screw is rotatably connected in the groove. The lead screw is threadedly connected to the nut. The bottom end of the lead screw extends out of the bottom of the groove and is fixedly connected to a crank.

[0008] Furthermore, a set of sliding grooves are opened inside the protective cover, and the sliding grooves are symmetric about the groove.

[0009] A set of sliding blocks are fixedly connected to the outer side of the cross plate, and the sliding blocks are slidably connected to the sliding grooves.

[0010] Further, one end of the rotating shaft is fixedly connected with a gear; a bottom surface of the top plate is fixedly connected with an "L"-shaped fixing plate, the fixing plate is provided with a through hole, a connecting rod is inserted through the through hole, a top end of the connecting rod is fixedly connected with a movable plate, and a plurality of tooth blocks capable of meshing with the gear are fixedly connected to a top of the movable plate;

[0011] A surface of the connecting rod is sleeved with a spring, two ends of the spring respectively abut against the movable plate and the fixing plate, and a bottom end of the connecting rod extends out of the through hole and is fixedly connected with a pull ring.

[0012] Further, two ends of an inner side of the cross plate are respectively fixedly connected with second connecting plates, and the rotating shaft is fixedly connected with the second connecting plates.

[0013] Further, two ends of an inner side of the cross plate are respectively fixedly connected with a group of second connecting plates, and the first connecting plate is located in the middle of the group of second connecting plates.

[0014] Further, bearings are fixedly connected to both a top and a bottom of the groove, and two ends of the lead screw are respectively installed in the groove through the bearings.

[0015] Further, one ends of the first connecting plate and the second connecting plate close to each other are both rounded corners.

[0016] Further, cross sections of the sliding groove and the sliding block are both isosceles trapezoids.

[0017] Further, a bottom of the base is fixedly connected with support legs.

[0018] A working method of a protective cover structure for a machining device includes the following steps:

[0019] When it is necessary to adjust the height of the protective cover, rotate the crank to drive the lead screw to rotate and move upward or downward relative to the nut, thereby driving the protective cover to move to the required height;

[0020] When it is necessary to adjust the angle of the protective cover, pull down the pull ring to drive the movable plate to move downward to separate the gear from the tooth blocks on the movable plate, flip the protective cover to rotate the rotating shaft relative to the connecting plate to adjust the protective cover to the required angle; when the protective cover is adjusted to a suitable angle, release the pull ring, and the elastic restoring force of the spring pushes the movable plate upward to make the tooth blocks mesh with the gear, thereby fixing the protective cover to the current position.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] In the present invention, turning the crank handle drives the screw rod to rotate, causing the screw rod to rotate and move upward or downward relative to the nut, thereby driving the protective cover to move to the required height. Subsequently, the height of the protective cover can be adjusted according to the size of the workpiece, playing a good protective role and preventing debris from splashing during drilling or grinding, thus affecting the operation of the operator. When the protective cover structure is not in use, the protective cover can be moved to the highest position, thereby releasing the space between the base and the top plate without affecting the use of the base.

[0023] Through the cooperation of the provided sliding groove and the slider, it plays a guiding role in the up and down movement of the protective cover, enabling the protective cover to move up and down more smoothly. At the same time, it shares the force acting on the screw rod and extends the service life of the screw rod.

[0024] In the present invention, by pulling down the pull ring, the movable plate can be driven to move downward, causing the gear to separate from the tooth block on the movable plate. Manually flip the protective cover to rotate the rotating shaft relative to the first connecting plate to adjust the protective cover to the required angle; when the protective cover is adjusted to the appropriate angle, release the pull ring, and the elastic restoring force of the spring pushes the movable plate upward to engage the tooth block with the gear, thereby fixing the protective cover to the current position and preventing it from returning to the initial position under the action of gravity; it can be seen that the present invention can reasonably adjust the included angle between the two protective covers according to the shape of the workpiece and the position of grinding and cutting, playing a good protective role.

Detailed implementation mode

[0032] The following further elaborates on the specific content of the present invention in conjunction with embodiments.

[0033] As Figures 1 to 6 shown, a protective cover structure for a machining device includes a base 1 fixedly installed with 4 support legs 2 at the bottom. Four support rods 4 are fixedly connected to the top of the base 1. The top ends of the support rods 4 are fixedly installed with a top plate 3. The four support legs 2 and the support rods 4 are arranged in a rectangular array. Protective cover structures are provided on both the left and right sides of the top plate 3. The protective cover structure includes a protective cover 5 and a cross plate 6. At both ends of the inner side of the cross plate 6, a group of second connecting plates 8 are respectively fixedly connected. A rotating shaft 9 is fixedly connected to the second connecting plate 8 through a hole. Both ends of the rotating shaft 9 are rotatably connected to a first connecting plate 7. The first connecting plate 7 is located between a group of second connecting plates 8. The first connecting plate 7 is fixedly connected to the side surface of the top plate 3. A nut 12 and a group of sliders 10 are fixedly connected to the outer side of the cross plate 6;

[0034] A vertical groove 13 and a group of sliding grooves 11 are opened on the inner side of the protective cover 5. The group of sliding grooves 11 are symmetric about the groove 13. The sliders 10 are slidably connected in the sliding grooves 11. The groove 13 is opened at the central position of the protective cover 5. Bearings 15 are fixedly connected to both the top and bottom of the groove 13. Both ends of the lead screw 14 are fixedly connected to the inner surface of the bearing 15. The bottom end of the lead screw 14 extends out of the bottom of the groove 13 and is fixedly connected to a crank 16. By rotating the lead screw 14 through the crank 16, the lead screw 14 moves up and down relative to the nut 12. At the same time, the slider 10 slides in the sliding groove 11 to play a guiding role. Finally, the lead screw 14 drives the protective cover 5 to move up and down to realize the height adjustment of the protection structure.

[0035] One end of the rotating shaft 9 is fixedly sleeved with a gear 17; a "L"-shaped fixing plate 21 is fixedly connected to the bottom surface of the top plate 3. A through hole 24 is opened in the fixing plate 21. A connecting rod 23 is passed through the through hole 24. The top end of the connecting rod 23 is fixedly connected to a movable plate 18. A number of tooth blocks 19 capable of meshing with the gear 17 are fixedly connected to the top of the movable plate 18. The tooth blocks 19 are arranged linearly; a spring 20 is sleeved on the surface of the connecting rod 23. One end of the spring 20 abuts against the movable plate 18, and the other end of the spring 20 abuts against the fixing plate 21. The bottom end of the connecting rod 23 extends out of the through hole 24 and is fixedly connected to a pull ring 22. Pulling the pull ring 22 downward drives the movable plate 18 to move downward, separating the gear 17 from the movable plate 18 and releasing the limit on the gear 17. Manually flip the protective cover 5 to rotate the rotating shaft 9 relative to the first connecting plate 7 to adjust the protective cover 5 to the required angle; when the protective cover 5 is adjusted to the appropriate angle, release the pull ring 22, and the elastic restoring force of the spring 20 pushes the movable plate 18 upward to make the tooth blocks 19 mesh with the gear 17, thereby fixing the protective cover 5 at the current position.

[0036] Preferably, the through hole 24 is a square hole or a circular hole. Correspondingly, the connecting rod 23 is also a cuboid or a cylinder.

[0037] Preferably, the ends of the first connecting plate 7 and the second connecting plate 8 close to each other are both rounded corners.

[0038] Preferably, the cross-sections of the sliding groove 11 and the slider 10 are both isosceles trapezoid structures.

[0039] A working method for a protective cover structure on a machining device, comprising the following steps:

[0040] When the height of the protective cover 5 needs to be adjusted, rotate the crank 16. The crank 16 drives the lead screw 14 to rotate. The lead screw 14 moves upward or downward relative to the nut 12, thereby driving the protective cover 5 to move upward or downward. At the same time, the slider 10 slides along the sliding groove 11 to play a guiding role. When the height of the protective cover 5 is adjusted to the required height, stop rotating the crank 16;

[0041] When the angle of the protective cover 5 needs to be changed, pull down the pull ring 22. The pull ring 22 drives the movable plate 18 to move downward through the connecting rod 23, so that the tooth block 19 moves away from the gear 17, thereby releasing the fixation of the gear 17. At this time, the spring 20 is in a compressed state; after flipping the protective cover 5 to a suitable angle, release the pull ring 22. The movable plate 18 drives the tooth block 19 to move upward under the elastic restoring force of the spring 20 until it meshes with the gear 17, thereby fixing the gear 17, and further fixing the protective cover 5 at the required angle;

[0042] When the protective cover structure is not needed, the protective cover 5 can be moved upward to the highest position by rotating the crank 16, thereby releasing the space between the top plate 3 and the base 1, which is convenient for operating on the base 1.
