Description

Technical Field

[0001] This application relates to the technical field of sheet metal processing, and in particular to a sheet metal drilling device. Background Technology

[0002] Currently, sheet metal processing is an indispensable basic process in modern manufacturing, especially in the fields of automobiles, aerospace, electronic communications, home appliances, and chassis cabinets. Among them, drilling, as one of the most basic and frequent processes in sheet metal processing, undertakes the core task of providing precise hole positions for subsequent assembly (such as riveting and bolting), wiring (electrical wiring harness through holes), heat dissipation (ventilation holes), and other functional requirements.

[0003] Existing sheet metal drilling equipment generally includes a frame, a worktable mounted on top of the frame, and a drilling device mounted on top of the frame. During operation, the sheet metal part is placed on top of the worktable, and then the drilling device drills holes in the sheet metal part.

[0004] However, the drilling device mentioned above generates debris when drilling sheet metal parts, and most of the debris accumulates on the worktable. The device is not convenient for handling the debris on the top of the worktable. Summary of the Invention

[0005] To facilitate the handling of debris from the top of the workbench, this application provides a sheet metal drilling device, employing the following technical solution:

[0006] A sheet metal drilling device includes a frame, a worktable mounted on the top of the frame, and a drilling device mounted on the top of the frame. A vertical plate is fixedly connected to the top of the frame, and a horizontal shaft is rotatably connected to the vertical plate. The horizontal shaft is fixedly connected to the worktable. A material receiving port is provided on the frame, and one end of the worktable is positioned corresponding to the material receiving port. A material receiving box is installed inside the material receiving port. A drive mechanism for tilting the worktable toward the material receiving port and a fixing mechanism for fixing the worktable are installed inside the frame.

[0007] When it is necessary to clean the top of the workbench, first loosen the fixing mechanism to secure the workbench, and then drive the workbench towards the receiving port using the drive mechanism. This allows the debris on the top of the workbench to be poured into the receiving box, thus enabling the cleaning of the top of the workbench. In summary, by adopting the above technical solution, it is convenient to clean the top of the workbench.

[0008] Optionally, the drive mechanism includes a vertical slot formed on the top of the frame, a cylinder installed in the vertical slot, and a push plate fixed to the piston rod of the cylinder; a receiving plate is fixed to one end of the worktable away from the receiving port, and the push plate can push the receiving plate to rotate.

[0009] By adopting the above technical solution, when it is necessary to drive the worktable to tilt towards the receiving port, the cylinder is first activated. At this time, the piston rod of the cylinder drives the push plate to move upward. The upward movement of the push plate can push the bearing plate to rotate upward. The upward rotation of the bearing plate can make the worktable tilt towards the receiving port. In summary, the drive mechanism is designed to facilitate the tilting of the worktable towards the receiving port.

[0010] Optionally, the fixing mechanism includes a mounting slot formed on one side of the vertical groove, a first lead screw rotatably connected to the inner wall of the mounting slot, and a first guide rod fixed to the inner wall of the mounting slot; a movable plate is threaded onto the first lead screw, and the movable plate is slidably connected to the first guide rod; multiple fixed plates are fixedly connected to the top of the movable plate, and each fixed plate has a spherical surface at its top; multiple through holes are formed on the top wall of the mounting slot, and the fixed plates are slidably connected to the through holes one by one; multiple fixed slots are formed on the bottom of the worktable, and the fixed plates are inserted into the fixed slots one by one, and each fixed slot has a chamfered surface at its opening; multiple support springs are fixedly connected to the bottom of the worktable, and the end of each support spring away from the worktable is fixedly connected to the top of the frame; a transmission assembly for driving the first lead screw to rotate is installed in the mounting slot.

[0011] By adopting the above technical solution, when it is necessary to fix the worktable, the first lead screw is first driven to rotate through the transmission component. The rotation of the first lead screw drives the moving plate to move upward. The moving plate moves upward and drives multiple fixed plates to move upward. This allows multiple fixed plates to be inserted into multiple fixed slots, thereby fixing the worktable. In summary, the fixing mechanism facilitates the fixing of the worktable.

[0012] Optionally, the transmission assembly includes a vertical tube rotatably connected to the inner wall of the mounting groove, a drive rod disposed within the vertical tube, a first gear sleeved and fixed to the outer wall of the vertical tube, and a second gear fixed to the first lead screw; the piston rod of the cylinder is fixedly connected to a horizontal plate, and the bottom of the drive rod is fixedly connected to the top of the horizontal plate; multiple helical blocks are fixedly connected to the side wall of the drive rod, and multiple helical grooves are opened on the inner wall of the vertical tube, with the helical blocks and the helical grooves corresponding to each other; the first gear meshes with the second gear.

[0013] By adopting the above technical solution, when the piston rod of the cylinder moves upward, it drives the horizontal plate to move upward. The upward movement of the horizontal plate drives the drive rod to move upward. Then, under the action of the spiral block and the spiral groove, the drive rod drives the vertical tube to rotate. The rotation of the vertical tube drives the first gear to rotate. The rotation of the first gear drives the second gear to rotate. The rotation of the second gear drives the first lead screw to rotate. In summary, the piston rod of the cylinder can synchronously drive the first lead screw to rotate, which facilitates the rotation of the first lead screw and saves energy.

[0014] Optionally, baffles are bolted to both sides of the top of the workbench.

[0015] By adopting the above technical solution, the baffle is set to guide the debris on the top of the workbench, which makes it easier to pour the debris from the top of the workbench into the receiving box.

[0016] Optionally, the receiving box is detachably connected to the receiving port via a connecting mechanism. The connecting mechanism includes a fixed limiting plate bolted to the top of the frame, a horizontal groove formed on one side of the receiving port, a movable limiting plate slidably connected to the horizontal groove, and a connecting spring fixed to the movable limiting plate on the side away from the receiving box. The top and bottom of the receiving box abut against the opposite inner sides of the fixed limiting plate and the movable limiting plate, respectively. The movable limiting plate has an inclined surface on the side near the receiving box, which matches the side wall of the receiving box. The end of the connecting spring away from the movable limiting plate is fixed to the inner wall of the horizontal groove. A driving mechanism is installed on the frame for releasing the limiting position of the receiving box and driving the receiving box to move downward.

[0017] By adopting the above technical solution, when it is necessary to install the receiving box, the receiving box is first moved upward from the bottom of the receiving port. At this time, the receiving box is driven by the inclined plane to move the movable limiting plate into the horizontal groove. The movable limiting plate moves into the horizontal groove and presses against the connecting spring. After the receiving box moves above the movable limiting plate, the movable limiting plate moves out of the horizontal groove under the action of the connecting spring. Then, under the limitation of the fixed limiting plate and the movable limiting plate, the receiving box can be installed. In summary, the connection mechanism is designed to facilitate the installation of the receiving box.

[0018] Optionally, the driving mechanism includes a slide groove on one side of the frame, a driving plate that slides vertically along the slide groove, and a driving assembly installed in the slide groove for driving the driving plate to move; the driving plate has a locking hole, the top opening of the locking hole has a chamfered surface, the bottom of the receiving box is fixedly connected to a locking plate, the locking plate is locked into the locking hole, the friction between the locking plate and the inner wall of the locking hole is much greater than the friction between the movable limiting plate and the side wall of the receiving box; the top of the driving plate can slide and connect to the inner wall of the receiving port, and the inclined surface matches the side wall of the driving plate; a horizontal plate is installed at the bottom of the frame, the top of the horizontal plate is fixedly connected to a push rod, the push rod can slide vertically into the locking hole and abut against the bottom of the locking plate.

[0019] By adopting the above technical solution, when it is necessary to release the constraint of the docking box, the drive plate is first driven upward by the drive assembly. The upward movement of the drive plate allows the locking plate to engage with the locking hole, and under the action of the inclined surface, it can drive the movable limiting plate to move into the horizontal groove, thereby releasing the constraint of the docking box. Then, the drive plate is driven downward by the drive assembly. The downward movement of the drive plate drives the receiving box downward. Then, under the action of the push rod, the locking plate can be separated from the locking hole, which facilitates the cleaning of the material in the docking box. In summary, the drive mechanism facilitates the release of the constraint of the docking box and the downward movement of the receiving box.

[0020] Optionally, the driving assembly includes a drive motor mounted on the top wall of the chute, a second lead screw fixed to the output shaft of the drive motor, and a second guide rod fixed to the inner wall of the chute; the driving plate is threaded to the second lead screw, and the driving plate is slidably connected to the second guide rod.

[0021] By adopting the above technical solution, when it is necessary to drive the moving plate to move, the drive motor is started first. At this time, the output shaft of the drive motor drives the second lead screw to rotate, and the rotation of the second lead screw can drive the moving plate to move. In summary, the set moving component facilitates the movement of the moving plate.

[0022] Optionally, the inner wall of the receiving port is equipped with an impact mechanism for impacting the bottom of the worktable. The impact mechanism includes a perforation in the inner wall of the receiving port, a rotating shaft rotatably connected to the inner wall of the perforation, a cam eccentrically connected to the rotating shaft, and an impact member abutting against the circumferential surface of the cam.

The reset block is fixedly connected to the side wall of the impact member. A reset spring is fixedly connected to one side of the reset block. The end of the reset spring away from the reset block is fixedly connected to the inner wall of one end of the reset groove.

[0023] By adopting the above technical solution, the drive plate moves upward, causing the rack to move upward. The upward movement of the rack drives the third gear to rotate. The rotation of the third gear drives the rotating shaft to rotate. The rotation of the rotating shaft drives the cam to rotate. The rotation of the cam drives the impact component to move back and forth, thus impacting the worktable and facilitating further cleaning of the top of the worktable. In summary, the impact mechanism facilitates further cleaning of the top of the worktable.

[0024] Optionally, the impact member includes a sleeve and an extension rod threaded to the inner wall of the sleeve.

[0025] By adopting the above technical solution, the sleeve and extension rod are designed to facilitate the adjustment of the length of the impact component, thereby adjusting the impact force on the worktable.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. When it is necessary to clean the top of the workbench, first loosen the fixing mechanism to the workbench, and then drive the workbench towards the receiving port through the drive mechanism. This allows the debris on the top of the workbench to be poured into the receiving box, thus enabling the cleaning of the top of the workbench. In summary, by adopting the above technical solution, it is convenient to clean the top of the workbench.

[0028] 2. When the piston rod of the cylinder moves upward, it drives the horizontal plate to move upward. The upward movement of the horizontal plate drives the drive rod to move upward. Then, under the action of the spiral block and the spiral groove, the drive rod drives the vertical tube to rotate. The rotation of the vertical tube drives the first gear to rotate. The rotation of the first gear drives the second gear to rotate. The rotation of the second gear drives the first lead screw to rotate. In summary, the piston rod of the cylinder can synchronously drive the first lead screw to rotate. This facilitates the rotation of the first lead screw and saves energy.

[0029] 3. When it is necessary to release the constraint of the docking box, the drive plate is first driven upward by the drive assembly. The upward movement of the drive plate allows the clamping plate to engage with the clamping hole, and under the action of the inclined plane, it can drive the movable limiting plate to move into the horizontal groove, thereby releasing the constraint of the docking box. Then, the drive plate is driven downward by the drive assembly. The downward movement of the drive plate drives the receiving box downward. Then, under the action of the push rod, the clamping plate can be separated from the clamping hole, which facilitates the cleaning of the material in the docking box. In summary, the drive mechanism is designed to facilitate the release of the constraint of the docking box and drive the receiving box to move downward. Attached Figure Description

When it is necessary to drive the worktable 11 to tilt towards the receiving port 15, the cylinder 22 is activated first. At this time, the piston rod of the cylinder 22 drives the push plate 23 to move upward. The upward movement of the push plate 23 can push the receiving plate to rotate upward. The upward rotation of the receiving plate can make the worktable 11 tilt towards the receiving port 15. In summary, the drive mechanism 2 is designed to facilitate the tilting of the worktable 11 towards the receiving port 15.

A driving mechanism 6 is installed on the frame 1 for releasing the limiting of the receiving box 16 and driving the receiving box 16 to move downward. When the receiving box 16 needs to be installed, the receiving box 16 is first moved upward from the bottom of the receiving port 15. At this time, the receiving box 16 is driven by the inclined surface 531 to move the movable limiting plate 53 into the horizontal groove 52. The movable limiting plate 53 moves into the horizontal groove 52 and presses against the connecting spring 54. After the receiving box 16 moves above the movable limiting plate 53, the movable limiting plate 53 moves out of the horizontal groove 52 under the action of the connecting spring 54.

The upward movement of the drive plate 62 allows the clamping plate 63 to engage with the clamping hole 621, and under the action of the inclined surface 531, it can drive the movable limiting plate 53 to move into the horizontal groove 52, thereby releasing the constraint of the docking box 16. Then, the drive plate 62 is driven downward by the drive assembly 7. The downward movement of the drive plate 62 drives the receiving box 16 downward.

The reset block 881 is fixed to the side wall of the impact member 84. A reset spring 882 is vertically fixed to one side of the reset block 881. The end of the reset spring 882 away from the reset block 881 is fixed to the inner wall of one end of the reset groove 88. The upward movement of the drive plate 62 causes the rack 85 to move upward, which in turn drives the third gear 87 to rotate. The rotation of the third gear 87 drives the rotating shaft 82 to rotate, which in turn drives the cam 83 to rotate. The rotation of the cam 83 drives the impact member 84 to reciprocate, thus impacting the worktable 11 and facilitating further cleaning of the top of the worktable 11. In summary, the impact mechanism 8 facilitates further cleaning of the top of the worktable 11.

[0048] Reference Figure 2 and Figure 5 The impact member 84 includes a sleeve 841 and an extension rod 842 threaded to the inner wall of the sleeve 841.
