A drill press guard

Abstract

This application relates to a drill press protective device, including a drill press body, a support table fixed to the drill press body, a spindle slidably mounted on the drill press body, and a drill bit mounted on the spindle. A protective cover with an open top is fixed to the upper end of the support table, and a movable frame is slidably mounted on the upper end of the support table. A fixture table is horizontally slidably connected to the movable frame. This application uses a transparent protective cover with a U-shaped structure to surround the fixture table, and uses the downward movement of the drill bit to link the insertion of the first and second cover plates into the upper end of the protective cover to complete the closure. This can effectively block the splashing of drill debris, protecting the safety of personnel outside and preventing pollution of the surrounding environment. Rotating the second screw can drive the fixture table, fixture, and first screw to move longitudinally as a whole, and the sliding plate always fits against the protective cover during movement to avoid protective gaps. Rotating the first screw can also make the fixture table finely adjusted longitudinally along the movable frame. The workpiece position can be adjusted without disassembling the protective cover throughout the process to adapt to drilling needs in different positions.

Description

Technical Field

[0001] This application relates to the field of drill press protection technology, and in particular to a drill press protection device. Background Technology

[0002] Bench-mounted drilling machines, as small drilling and machining equipment, are primarily used for light-duty operations such as drilling, reaming, boring, and tapping small workpieces. They are suitable for materials such as wood, plastics, non-ferrous metals, and thin steel plates.

[0003] When a bench drill is working, the motor provides power, and the speed is adjusted to a suitable speed through the belt or gear transmission mechanism in the spindle box, which drives the spindle to rotate. The drill bit is fixed at the lower end of the spindle by a chuck. The operator manually rotates the feed handwheel to drive the spindle to press down, so that the high-speed rotating drill bit contacts the workpiece surface. By controlling the feed force and depth, the drill bit cuts the workpiece material and gradually drills a hole in the workpiece.

[0004] During the drilling process, bench drills drill holes in the workpiece by moving the drill bit downwards. Because a large amount of debris is generated during the drilling process, it is easy to splash, causing environmental pollution and threatening the health of personnel. In the existing technology, a protective cover is usually installed to block the debris from splashing. However, every time the workpiece position needs to be adjusted, the protective cover needs to be removed to expose the workpiece and the fixture used to hold the workpiece, which is very inconvenient to operate.

[0005] Therefore, those skilled in the art have provided a drill press protection device to solve the problems mentioned in the background art. Utility Model Content

[0006] To address the problems mentioned in the background art, this application provides a drill press protection device.

[0007] The drilling machine protection device provided in this application adopts the following technical solution:

[0008] A drill press protective device includes a drill press body, a support platform fixed to the drill press body, a spindle slidably mounted on the drill press body, and a drill bit mounted on the spindle. A protective cover with an open top is fixed to the upper end of the support platform. A movable frame is slidably mounted on the upper end of the support platform. A clamping table is horizontally slidably connected to the movable frame. A first screw is rotatably connected to the clamping table. The first screw is threadedly connected to the bottom end of the clamping table. A sliding plate is rotatably connected to one end of the first screw. The sliding plate is horizontally slidably connected to the inner wall of the protective cover. A first cover plate and a second cover plate are rotatably mounted on the outer wall of the spindle. A baffle surrounding the outer surface of the spindle is fixed to the upper end of both the first cover plate and the second cover plate.

[0009] The protective cover is made of transparent material, allowing a clear view of the internal workpiece processing.

[0010] Preferably, the inner wall of the support platform has two sliders slidably connected, and the two ends of the movable frame are respectively fixedly connected to the upper ends of the two sliders.

[0011] Preferably, the support platform is rotatably connected to a second screw, the second screw is threadedly connected to one of the sliders, and a wheel is fixed to one end of the second screw.

[0012] Preferably, the slide plate fits inside the protective cover, both ends of the slide plate extend outwards to both sides of the protective cover, and the bottom end of the slide plate fits against the upper surface of the support platform.

[0013] Preferably, an L-shaped support frame is fixedly connected to the outer wall of the main shaft, and one end of both the first cover plate and the second cover plate is rotatably connected to the support frame.

[0014] Preferably, the first cover plate and the second cover plate are attached to the outer surface of the main shaft, the upper end of the first cover plate is fixed with a U-shaped limiting buckle, and the upper end of the second cover plate is rotatably connected with an L-shaped buckle.

[0015] In this invention, the buckle is inserted into the inner wall of the limiting buckle to limit the first cover plate and the second cover plate, preventing the first cover plate and the second cover plate from detaching from the main shaft. A torsion spring shaft (not shown in the figure) can be set between the buckle and the second cover plate to increase the rotation resistance of the buckle.

[0016] In summary, this application includes the following beneficial technical effects:

[0017] 1. This application uses a transparent protective cover with a U-shaped structure to surround the fixture table, and uses the first and second cover plates inserted into the upper part of the protective cover to complete the seal by moving the drill bit down. This can effectively block the flying of drill debris, protect the safety of outside personnel, and prevent the surrounding environment from being polluted.

[0018] 2. Rotating the second screw can drive the fixture table, fixture and the first screw to move longitudinally as a whole, and the slide plate is always in contact with the protective cover during the movement to avoid protective gaps; rotating the first screw can also make the fixture table finely adjusted longitudinally along the movable frame, and the workpiece position can be adjusted without disassembling the protective cover throughout the process to adapt to drilling needs in different positions.

[0019] 3. The closing action of the protective cover is combined with the drilling action of the drill bit moving down to drill, eliminating the need for additional manual operation of the protective structure. At the same time, the workpiece position adjustment is completed under the protection of the protective cover, which not only saves the steps of repeatedly disassembling and installing the protective cover, but also ensures that the protection is not interrupted during the adjustment process, thus improving work efficiency.

Detailed Implementation

[0025] 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.

[0026] like Figures 1-4As shown, this application discloses a drill press protective device, including a drill press body 1, a support platform 3 fixed to the drill press body 1, a main spindle 2 slidably mounted on the drill press body 1, and a drill bit 16 mounted on the main spindle 2. A protective cover 4 with an open top is fixed to the upper end of the support platform 3. A movable frame 15 is slidably mounted on the upper end of the support platform 3. A clamping table 14 is horizontally slidably connected to the movable frame 15. A first screw 6 is rotatably connected to the clamping table 14, and the first screw 6 is threadedly connected to the bottom end of the clamping table 14. A sliding plate 5 is rotatably connected to one end of the first screw 6, and the sliding plate 5 is horizontally slidably connected to the inner wall of the protective cover 4. A first cover plate 8 and a second cover plate 10 are rotatably mounted on the outer wall of the main spindle 2. A baffle 7 surrounding the outer surface of the main spindle 2 is fixed to the upper end of both the first cover plate 8 and the second cover plate 10. The upper end of the clamping table 14 is used to mount a clamp (not shown in the figure) to hold the workpiece. The drill bit 16 is moved downwards by the downward movement of the main spindle 2 to drill a hole in the workpiece. During the drilling process, a transparent U-shaped protective cover is provided around the clamping table 14. The protective cover 4 surrounds the entire area. When the spindle 2 moves downward, driving the drill bit 16 to move downward and drill, the first cover plate 8 and the second cover plate 10 move downward and insert into the upper part of the protective cover 4, covering the protective cover 4 to prevent debris from flying out and protecting personnel and the surrounding environment. In addition, by rotating the second screw 12, the slider 13 is driven to slide, driving the movable frame 15 and the fixture table 14 to move longitudinally on the support platform 3, and driving the first screw 6 to move together, so that the slide plate 5 slides inside the protective cover 4, keeping the slide plate 5 in contact with the protective cover 4 at all times, preventing the protective cover 4 from opening on one side. Then, by rotating the first screw 6, the fixture table 14 moves longitudinally along the movable frame 15, adjusting the position of the workpiece on the fixture table 14, which is convenient for drilling holes at different positions of the workpiece. In this way, the position of the workpiece can be adjusted without disassembling the protective cover 4, and the first cover plate 8 and the second cover plate 10 can be inserted into the protective cover 4 during the drilling process of the drill bit 16, preventing debris from flying out and causing pollution to the surrounding environment.

[0027] To support the sliding of the movable frame 15, two sliders 13 are slidably connected to the inner wall of the support platform 3, and the two ends of the movable frame 15 are fixedly connected to the upper ends of the two sliders 13 respectively.

[0028] The support platform 3 is rotatably connected to a second screw 12, which is threadedly connected to one of the sliders 13. A wheel 11 is fixed to one end of the second screw 12, and the wheel 11 is located at the end of the second screw 12 to facilitate manual rotation of the second screw 12.

[0029] The slide plate 5 fits inside the protective cover 4. Both ends of the slide plate 5 extend outward to both sides of the protective cover 4. The length of the slide plate 5 is greater than the width of the protective cover 4. The bottom end of the slide plate 5 fits against the upper surface of the support platform 3. In this way, when the second screw 12 rotates to drive the movable frame 15, the first screw 6 and the clamping platform 14 to move, the slide plate 5 slides along the inner wall of the protective cover 4 to adapt to the movement of the first screw 6 and block one side of the protective cover 4 to prevent debris from flying out.

[0030] An L-shaped support frame 9 is fixedly connected to the outer wall of the spindle 2. One end of the first cover plate 8 and the second cover plate 10 are rotatably connected to the support frame 9. By rotating the first cover plate 8 and the second cover plate 10, they are separated from the outer wall of the spindle 2, exposing the upper end of the protective cover 4, which facilitates the installation of workpieces on the fixture of the fixture table 14 for drilling work.

[0031] The first cover plate 8 and the second cover plate 10 are attached to the outer surface of the main shaft 2. The upper end of the first cover plate 8 is fixed with a U-shaped limiting buckle 17, and the upper end of the second cover plate 10 is rotatably connected with an L-shaped buckle 18. The buckle 18 is inserted into the inner wall of the limiting buckle 17. The buckle 18 is locked inside the limiting buckle 17 to prevent the first cover plate 8 and the second cover plate 10 from separating. By rotating the buckle 18 to disengage from the limiting buckle 17, the first cover plate 8 and the second cover plate 10 can be rotated to separate from the main shaft 2.

[0032] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0033] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0034] Working principle: The spindle 2 moves downward, driving the drill bit 16 downward to drill holes in the workpiece. During the drilling process, a transparent protective cover 4 with a U-shaped structure is set around the fixture table 14 to surround the workpiece. When the spindle 2 moves downward, driving the drill bit 16 downward, the first cover plate 8 and the second cover plate 10 move downward and insert into the upper part of the protective cover 4, covering the protective cover 4 to prevent debris from flying out and to protect personnel and the surrounding environment. In addition, by rotating the second screw 12, the slider 13 is driven to slide, driving the movable frame 15 and the fixture table 14 to move longitudinally on the support platform 3, and driving the first screw 6 to move together, so that the slide plate 5 slides inside the protective cover 4, keeping the slide plate 5 in contact with the protective cover 4 at all times, preventing the protective cover 4 from opening on one side. Then, by rotating the first screw 6, the fixture table 14 moves longitudinally along the movable frame 15, adjusting the position of the workpiece on the fixture table 14 to facilitate drilling holes at different positions on the workpiece.
