Description

Technical Field

[0001] This utility model belongs to the field of drilling tooling technology, and specifically relates to a drilling fixture. Background Technology

[0002] Existing drilling fixtures typically include a clamping structure on top of a base plate, with a blower mechanism slidingly mounted on top of the base plate. During use, the clamping mechanism is first activated to clamp the material, then holes are drilled into the clamped aluminum plate. After drilling, the blower mechanism moves to blow away any remaining debris near the hole. However, in actual use, because the fan is fixedly positioned at the top of the blower mechanism, the debris not directly under the fan receives less airflow, resulting in some debris remaining on the workpiece surface. When the operator uses the drilling mechanism to drill through this blown-out surface, the remaining debris can scratch the inside of the hole during drilling, leading to defective products that do not meet user requirements.

[0003] For example, the utility model patent with announcement number CN218694181U discloses a drilling fixture. In the technical solution of this patent, a moving mechanism is provided on the top of the base plate, and a fan is fixedly provided on the top of the moving mechanism. When the fan cleans the debris on the top of the workpiece, the debris in places not directly blown by the wind is not cleaned, which will result in incomplete cleaning of the debris on the top of the workpiece. When the worker drills a hole in the cleaned area, the debris will scratch the inner wall of the hole during the drilling process, resulting in defective products that do not meet the needs of users. Therefore, a drilling fixture is proposed. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the prior art by providing a drilling fixture that not only meets the basic requirements for clamping workpieces, but also allows for the rotation of the blower mechanism to thoroughly clean debris from the top of the workpiece. This prevents debris from remaining when the airflow is weak, thus avoiding damage to the inner wall of the drill hole and preventing defective products, thereby meeting people's usage needs.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a drilling jig, including a base plate, a moving mechanism is provided on the top of the base plate, the moving mechanism includes fixed blocks provided on the front and rear sides of the top of the base plate, the middle part of the two fixed blocks is provided with an upward-facing sliding groove, the inside of the two sliding grooves is provided with a slider, the inside of the two sliding grooves is provided with a lead screw passing through the slider, the right end of the two sliders is provided with a first rotary motor connected to the lead screw, the first rotary motor is connected to the lead screw through a coupling, the top of the two sliders is provided with an electric telescopic rod, and a rotating mechanism is provided between the two electric telescopic rods.

[0006] As a further improvement of this utility model, the top of the two electric telescopic rods of the rotating mechanism are respectively provided with support plates, and the inner ends of the two support plates are respectively provided with rotating rods. A square frame is provided between the two rotating rods. The rear end of the rear support rod is provided with a first rotating motor connected to the rotating rod. The first rotating motor is connected to the rotating rod through a coupling. A rotating blower mechanism is provided on the square frame.

[0007] As a further improvement of this utility model, the rotary blower mechanism includes two rotating shafts disposed on the top side inside the frame, two rotating shafts disposed at the bottom inside the frame, a fan disposed between the corresponding rotating shafts, a synchronous pulley disposed on the top of each of the two rotating shafts, a transmission belt disposed between the two synchronous pulleys, an L-shaped frame disposed on the rear top side of the frame, a second rotary motor disposed inside the L-shaped frame and connected to the synchronous pulleys, the second rotary motor and the synchronous pulleys being connected by a coupling, and a clamping mechanism disposed on the top of the base plate.

[0008] As a further improvement of this utility model, the clamping mechanism includes a slide rail located in the middle of the base plate. Two sliding bodies are arranged inside the slide rail. A bidirectional lead screw passes through the sliding bodies inside the slide groove. A third rotary motor connected to the bidirectional lead screw is located on the right side of the base plate. The third rotary motor and the bidirectional lead screw are connected via a coupling. Placement plates are respectively provided on the top of the two sliding bodies. L-shaped plates are respectively provided on the top of the two placement plates. Two guide strips are respectively provided on the inner ends of the two L-shaped plates. Two threaded rods are respectively provided on the two L-shaped plates. Rotary seats are respectively provided at the bottom of the four threaded rods. Pressure plates are respectively provided at the bottom of the four rotary seats. Guide grooves corresponding to the guide strips are respectively provided on the inner ends of the four pressure plates. Handwheels are respectively provided on the top of the four threaded rods.

[0009] As a further improvement of this utility model, top blocks are respectively provided on the inner ends of the two L-shaped plates, mounting plates are respectively provided at the four corners of the bottom plate, mounting grooves are respectively provided on the four mounting plates, and a switch is provided on the top left side of the bottom plate. The switch is electrically connected to the first rotary motor and the second rotary motor.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] Firstly, this design includes a first rotary motor. The rotation of the first rotary motor drives the lead screw to rotate, which in turn drives the slider located inside the slide groove to move. The movement of the slider causes the blower mechanism to move in the left and right directions, thereby facilitating the blower mechanism to thoroughly clean the residue on the top of the workpiece.

[0012] Secondly, this design includes a second rotary motor. The rotation of the second rotary motor drives the rotating rod to rotate, which in turn drives the square frame to rotate. This causes the rotary blower to rotate around the rotating rod, facilitating the thorough cleaning of debris from the top of the workpiece.

[0013] Thirdly, this design includes a third rotary motor. The rotation of the third rotary motor drives the synchronous pulley to rotate, which in turn drives the rotating shaft to rotate, thereby causing the fan to rotate. The rotation of the fan can thoroughly clean the debris on the top of the workpiece around the rotating shaft.

[0014] Fourth, this design includes a fourth rotary motor. The rotation of the fourth rotary motor drives the bidirectional lead screw to rotate, which in turn moves the slide body inside the slide rail, thereby fixing the workpiece by the top block. At this time, the operator rotates the handwheel, which drives the threaded rod to rotate on the L-shaped plate. The pressure plate at the bottom of the threaded rod then presses the workpiece.

[0027] How to use this utility model:

[0028] The user first starts the fourth rotary motor 209. The rotation of the fourth rotary motor 209 causes the two receiving plates to move. When they move to a suitable distance, the workpiece is placed on top of the receiving plate. Then, the operator rotates the handwheel 207.
