Description

Technical Field

[0001] This utility model relates to the field of drilling and processing technology for irregularly shaped parts, and in particular to an automatic drilling device for semi-circular arc-shaped components. Background Technology

[0002] Currently, when drilling irregularly shaped parts (semi-circular arc products) using drilling equipment, a fixed drill bit is usually used. The relative position of the product and the drill bit is changed by altering the product's placement and adjusting its angle. The drill bit then moves up and down along a single coordinate axis, and coordinate lines are drawn manually to create the hole in the semi-circular arc product. However, the above method is difficult to automate drilling of semi-circular arc products, and the drilling accuracy and efficiency are low. It also increases the intensity of manual operation and production costs. Summary of the Invention

[0003] This invention provides an automatic drilling device for semi-circular arc-shaped components to solve the above-mentioned technical problems.

[0004] To solve the above-mentioned technical problems, this utility model provides an automatic drilling device for semi-circular arc-shaped components, including a flat plate, a fixing mechanism, a rotating mechanism, a telescopic mechanism, and a drilling mechanism.

[0005] The flat plate is used to support the components to be processed;

[0006] The fixing mechanism includes a vertical cylinder and a pressure plate. The pressure plate is installed at the output end of the vertical cylinder and is located above the flat plate and corresponds to the position of the component to be processed.

[0007] The rotating mechanism includes a first motor, a belt, a wheel axle, and a swing arm. The belt is sleeved between the first motor and the wheel axle, and one end of the swing arm is fixedly mounted on the wheel axle.

[0008] The telescopic mechanism is installed at the other end of the swing arm and includes a second motor, a threaded rod, and a slider. The output end of the second motor is fixedly connected to one end of the threaded rod, and the slider is threaded onto the threaded rod.

[0009] The drilling mechanism is mounted on the slider and includes a double-rod cylinder and a drill bit mounted on the output end of the double-rod cylinder;

[0010] The fixing mechanism presses the component to be processed onto the flat plate; the rotating mechanism and the telescopic mechanism adjust the position and angle of the drill bit, and use the drill bit to drill holes in the component to be processed.

[0011] Preferably, the flat plate is equipped with a clamp for holding the component to be processed.

[0012] Preferably, the clamp includes at least two grippers, the position of which is adjustable on the flat plate.

[0013] Preferably, the gripper is provided with an elongated mounting hole, and the flat plate is provided with a fixing hole, and the installation is achieved by passing a bolt through the elongated mounting hole and the fixing hole.

[0014] Preferably, the flat plate is provided with a scale corresponding to the position of the gripper.

[0015] Preferably, the planar plate is further provided with a positioning block for determining the origin position of the drill bit.

[0031] The flat plate 10 is used to support the component to be processed (not shown);

[0032] The fixing mechanism 20 includes a vertical cylinder 21 and a pressure plate 22. The pressure plate 22 is installed at the output end of the vertical cylinder 21 and is located above the flat plate 10 and corresponds to the position of the component to be processed. The fixing mechanism 20 can be used to press the component to be processed onto the flat plate 10.

[0033] The rotating mechanism 30 includes a first motor 31, a belt 32, a wheel axle 33, and a swing arm 34. The belt 32 is sleeved between the first motor 31 and the wheel axle 33, and one end of the swing arm 34 is fixedly mounted on the wheel axle 33. The first motor 31 is connected to the wheel axle 33 through the belt 32, which in turn drives the swing arm 34 to swing, so that the drill bit 52 below can swing freely left and right by 180°.

[0034] The telescopic mechanism 40 is installed at the other end of the swing arm 34 and includes a second motor 41, a threaded rod 42 and a slider 43. The output end of the second motor 41 is fixedly connected to one end of the threaded rod 42. The slider 43 is threaded onto the threaded rod 42. By rotating the threaded rod 42 driven by the second motor 41, the vertical position of the slider 43 on the threaded rod 42 can be adjusted, thereby controlling the Z-axis movement of the drill bit 52.

[0035] The drilling mechanism 50 is mounted on the slider 43 and includes a double-rod cylinder 51 and a drill bit 52 mounted on the output end of the double-rod cylinder 51. After the position and angle of the drill bit 52 are adjusted by the rotation mechanism 30 and the telescopic mechanism 40, the double-rod cylinder 51 can drive the drill bit 52 to drill holes in the component to be processed.

[0036] This utility model achieves the function of free movement of drill bit 52 within any angle of 180° through the control combination of first motor 31, belt 32 and swing arm 34, thus breaking the conventional thinking of fixed drill bit of drilling machine, effectively solving the problems of inaccurate drilling position, deviation and low efficiency caused by relying on manual drawing of lines on the product or swinging the product angle to complete drilling, and realizing the drilling of arc-shaped multi-dimensional coordinate hole position.

[0038] In some embodiments, the planar plate 10 is provided with a scale (not shown) corresponding to the position of the gripper, which facilitates intuitive adjustment of the gripper position to quickly adapt to semi-circular products with different inner diameters.

[0039] In some embodiments, please refer to the following: Figure 1 and Figure 2 The planar plate 10 is also provided with a positioning block 12 for determining the origin position of the drill bit 52. For example, when the drill bit 52 is in contact with the positioning block 12, the position of the drill bit 52 is the origin position.

The control box 60 is connected to the vertical cylinder 21, the first motor 31, the second motor 41 and the double-rod cylinder 51 respectively, and then sends control signals to control the operation of the vertical cylinder 21, the first motor 31, the second motor 41 and the double-rod cylinder 51 to realize fully automatic drilling.

[0041] In some embodiments, the control box 60 may include an interactive screen for human-machine interaction. The interactive screen is used at least to set the coordinates of the drilling position, including the rotation angle of the first motor 31 (corresponding to the R-axis coordinate) and the vertical displacement of the second motor 41 (corresponding to the Z-axis coordinate). In some embodiments, the coordinates of the drilling position set by the interactive screen can be multiple sets; in this embodiment, at least 16 sets of coordinate values ​​can be input. In some embodiments, the interactive screen is also used to set the number of holes to be drilled, i.e., to complete drilling instructions for multiple holes at once, improving the drilling accuracy of the product's curved surface, reducing manual operation intensity and production costs, and realizing automatic drilling of semi-circular arc-shaped multi-dimensional coordinates.
