Description

Technical Field

[0001] The utility model belongs to the technical field of fastener drilling, in particular to a fastener drilling device. Background Art

[0002] Fasteners are a type of mechanical parts used for fastening connections and are extremely widely used. Various fasteners can be seen on various machines, equipment, vehicles, ships, railways, bridges, buildings, structures, tools, instruments, meters and supplies.

[0003] For example, the Chinese patent with the announcement number CN216540914U discloses a fastener drilling device, comprising a base plate, a track 1 and a sliding block, wherein the track 1 is fixedly connected to the upper left side of the base plate, and the upper end of the track 1 is movably connected to the sliding block. The utility model overcomes the shortcomings of the prior art. By providing a light bulb and an adjustment ring, when the drill bit is ready to drill a fastener to be processed, the light emitted by the light bulb surrounding the inner side of the changer will illuminate the fastener. Since the drill bit is located in the middle of the light bulb and the changer, the worker can adjust the position of the fastener to be drilled according to the light irradiated by the light bulb on the fastener, and the adjustment ring can adjust the range of the light irradiated by the light bulb, which is convenient for adjusting the light range according to the size of the fastener, thereby making the position of the hole drilled by the drill bit on the fastener more accurate, improving the quality of the processed fastener, and facilitating practical use.

[0004] The above patent has the following problems:

[0005] This patent has some shortcomings when used. For example, when fastening a fastener, the device requires the user to hold the fastener in hand to secure it between the two mounting plates. This process is inconvenient and not suitable for a single operator. In addition, when drilling holes in the fastener, a lot of debris is generated. This device is not easy to clean up the debris, and the debris scattered on the top of the base plate requires the operator to clean it up, which is quite troublesome. In view of this, we propose a fastener drilling device. Utility Model Content

[0006] The purpose of the present utility model is to provide a fastener drilling device to solve the problems raised in the above background technology.

[0007] In view of this, the present invention provides a fastener drilling device, comprising:

[0008] A workbench, a fixed plate is fixedly installed on the top of the workbench, a placement plate is plugged and installed on one side of the fixed plate, two clamping plates are provided on the top of the placement plate, and a plurality of arc-shaped grooves are provided on the opposite sides of the two clamping plates. A collection box is plugged and installed on the top of the workbench and located at the bottom of the placement plate, a leakage plate is fixedly installed in the collection box, and a sealing door is rotatably installed at the discharge port of the collection box, and one of the clamping plates is fixed to the fixed plate;

[0009] A power assembly, located on the workbench and used to drive the other clamping plate to move;

[0010] A chute is provided on the top of the workbench and on the other side of the fixed plate, an L-shaped plate is slidably installed in the chute, a second electric push rod is fixedly installed on the top of the L-shaped plate, an output end of the second electric push rod passes through the top of the L-shaped plate and is fixedly installed with a mounting frame, a second motor is fixedly installed in the mounting frame, and an output end of the second motor passes through the mounting frame and is fixedly installed with a drill bit;

[0011] A driving assembly is located in the slide groove and is used to drive the L-shaped plate to move.

[0012] In this technical solution, when in use, the staff places a number of fasteners on the top of the placement plate and in the rubber pads located in the arc grooves on the other clamping plate. After aligning it, the power assembly is provided to drive the other clamping plate to move toward one of the clamping plates until the rubber pads in the arc grooves on the other clamping plate contact the corresponding fasteners, so that the two clamping plates can clamp the fasteners. Then, the placement plate can be pulled out of the fixing plate, and the fasteners are fixed at this time.

[0013] Subsequently, the second motor can be started, and the output shaft of the second motor will drive the drill bit to rotate. Then, the second electric push rod can be started, and the output shaft of the second electric push rod will extend and drive the mounting frame to move downward until the drill bit contacts one of the fasteners and drills a hole in it. After drilling one of the fasteners, the mounting frame is restored to its original position, and the driving assembly is used to drive the L-shaped plate to move so that the drill bit moves to the top of another fastener. Then, the above operation is used to drill a hole in the other fastener. All the remaining fasteners can be drilled through the above operation.

[0014] After the drilling is completed, the power assembly is set up to drive the other clamping plate to move in the direction away from the fixed plate. At this time, several fasteners will be released and fall down to the top of the leak plate in the collection box, and the debris generated during drilling will also fall into the collection box. The debris will leak out from the leak plate and fall to the bottom of the inner cavity of the collection box. At this time, the fixed parts after the drilling will be collected in the collection box and located on the top of the leak plate, which is convenient for the staff to take. When the debris in the collection box needs to be cleaned, the collection box can be pulled out from the top of the workbench, and then the hand-tightening bolt can be turned by hand. Under the action of the thread, the hand-tightening bolt will be moved out from the sealing door, so that the sealing door is released, and then the sealing door can be rotated and opened. At this time, the discharge port of the collection box will be opened, and the staff can pour out the debris at the bottom of the inner cavity of the collection box.

[0015] In the above technical solution, further, the power assembly includes:

[0016] A support plate is fixedly mounted on the top of the workbench and located on the side of the collection box away from the fixed plate. Two electric push rods 1 are fixedly mounted on one side of the support plate, and the output ends of the two electric push rods 1 are fixed to one of the clamping plates.

[0017] In this technical solution, when the two electric push rods 1 are started, the output shafts of the two electric push rods 1 will shrink, and then the output shafts of the two electric push rods 1 will drive the other clamping plate to move in a direction away from the fixed plate.

[0019] A threaded rod is rotatably installed in the slide groove, one end of the threaded rod passes through the L-shaped plate, and a motor 1 is fixedly installed on one side of the workbench. The output end of the motor 1 passes through one side of the workbench and extends into the slide groove and is coaxially connected to the threaded rod.

[0020] In this technical solution, motor one is started so that the output shaft of motor one drives the threaded rod to rotate. Under the action of the thread, the threaded rod will drive the L-shaped plate to move.

[0021] In the above technical solution, further, the L-shaped plate is threadedly connected to the threaded rod, and the output shaft of the motor 1 is rotationally connected to the workbench and the slide groove.

[0022] In this technical solution, under the action of the thread, it is ensured that the L-shaped plate can be displaced when the threaded rod rotates, thereby ensuring that the motor 1 can operate normally.

[0023] In the above technical solution, further, a rubber pad is fixedly installed in the arc-shaped groove.

[0024] In this technical solution, under the action of the rubber pad, the material of the rubber pad is relatively soft and can avoid damage to the surface of the fastener, while at the same time can enhance the friction between the two splints and the fastener, making it more stable.

[0025] In the above technical solution, further, a hand-tightening bolt is installed on the inner thread of the sealing door, one end of the hand-tightening bolt passes through the collection box and extends to the outside, and the hand-tightening bolt is threadedly connected to the collection box.

[0026] In this technical solution, it is ensured that the sealed door can be released by hand-tightening the bolts, so that the sealed door can be opened or fixed.

[0027] In the above technical solution, further, the output shaft of the second electric push rod is slidingly connected to the L-shaped plate, and the output shaft of the second motor is rotationally connected to the mounting frame.

[0028] In this technical solution, it is ensured that the electric push rod 2 can operate normally; it is ensured that the motor 2 can operate normally.

[0029] In the above technical solution, further, a baffle is fixedly installed on the top of the workbench and located on the side of the collection box away from the motor, and the baffle is in contact with the collection box and the placement plate.

[0030] In this technical solution, it is ensured that the baffle can block the collection box and the placement plate, making it easier to install the collection box and the placement plate in place.

[0031] The beneficial effects of the utility model are:

[0032] 1. The fastener drilling device, through the cooperation between the fixed plate and the placement plate, when the two clamping plates clamp a number of fasteners, the fasteners can be placed on the top of the placement plate for clamping, which is more convenient to operate and can be completed by a single worker.

[0033] 2. The fastener drilling device ensures that the debris and the fasteners after drilling can be collected separately through the cooperation between the collection box, the sealing door and the leakage plate. There is no need for the staff to clean the debris later, which makes it more convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS
