Description

Technical Field

[0001] This application relates to the technical field of drilling devices, and particularly relates to a drilling device for machining. Background Art

[0002] Drilling in machining is one of the indispensable processes in modern industrial production. Through machining drilling, accurate perforations and hole positions can be provided for workpieces, improving product quality and production efficiency. In the machining process, controlling the drilling depth is one of the crucial links in the operation of the drilling machine, which is directly related to the quality of the workpiece and subsequent assembly. Currently, when drilling workpieces with different thicknesses, the drilling depth is often controlled by the moving distance of the drilling machine. This requires measuring data such as the distance between the drilling machine and the surface of the workpiece to be machined. Subtracting the distance between the drilling machine and the surface of the workpiece to be machined from the moving distance of the drilling machine gives the drilling depth. This method requires measurement before each drilling, which is rather inconvenient. Therefore, a drilling device for machining is proposed. Utility Model Content

[0005] A drilling device for machining includes a base. The base includes a vertical part and a horizontal part. The vertical part of the base is perpendicularly and fixedly installed at one end of the horizontal part. A liftable drilling mechanism is provided at the top of the vertical part of the base. Symmetrically arranged fixing plates are fixedly connected to both sides of the vertical part of the base. The two fixing plates are located on both sides of the drilling mechanism, and lifting plates are provided between the two fixing plates and the horizontal part of the base. First electric push rods are fixedly connected to both outer surfaces of the horizontal part of the base. The upper ends of the two first electric push rods are respectively fixedly connected to the two lifting plates.

[0006] Preferably, the drilling mechanism includes a second electric push rod fixedly installed on the upper part of the vertical part of the base. The second electric push rod is installed upside down. The telescopic end of the second electric push rod is fixedly connected to a mounting seat. A drilling machine is provided on one side of the lower surface of the mounting seat, and a display mechanism is provided on the other side of the lower surface of the mounting seat.

[0007] Preferably, the display mechanism includes a guide rod which is parallel to the drill rod of the drilling rig. A notch adapted to the guide rod is formed on the surface of the mounting seat. The guide rod penetrates through the notch and forms a moving pair inside the notch. Scale lines are arranged on the surface of the guide rod in the vertical direction. A spring is sleeved on the outer surface of the guide rod. The upper end of the spring is fixedly connected to the upper end of the guide rod, and the lower end of the spring is fixedly connected to the mounting seat. In the natural state, the spring makes the lower end of the guide rod flush with the drill rod of the drilling rig.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] The following further describes the present application in detail with reference to the attached Figures 1-3 drawings.

[0017] An embodiment of the present application discloses a drilling device for machining, including a base 1. The base 1 includes a vertical part and a horizontal part. The vertical part of the base 1 is perpendicularly and fixedly installed at one end of the horizontal part. A liftable drilling mechanism is provided at the top of the vertical part of the base 1. Symmetrically arranged fixing plates 2 are fixedly connected to both sides of the vertical part of the base 1. The two groups of fixing plates 2 are located on both sides of the drilling mechanism, and lifting plates 6 are provided between the two groups of fixing plates 2 and the horizontal part of the base 1. Electric push rods 3 are fixedly connected to both outer surfaces of the horizontal part of the base 1. The upper ends of the two groups of electric push rods 3 are respectively fixedly connected to the two groups of lifting plates 6.

[0018] In this embodiment, a clamping space is formed between the lower surface of the fixing plate 2 and the upper surface of the lifting plate 6. During use, the plate to be drilled is placed between the fixing plate 2 and the lifting plate 6, and the processing surface of the plate to be drilled is made to closely adhere to the lower surface of the fixing plate 2. Then, the first electric push rod 3 is driven to extend, driving the lifting plate 6 to move upward, so that the lifting plate 6 presses against the lower surface of the workpiece to be processed. The fixing plate 2 and the lifting plate 6 thus form a clamping part to stably clamp the workpiece to be processed. Therefore, when the present application drills holes in plates of different thicknesses, the processing surface of the plate to be processed is always flush with the lower surface of the fixing plate 2, that is, the initial distance between the workpiece processing surface and the drill 4 is the same. Therefore, the user can control the drilling depth by controlling the moving distance of the drilling mechanism.

[0019] Furthermore, the drilling mechanism includes a second electric push rod 5 fixedly installed on the upper part of the vertical part of the base 1. The second electric push rod 5 is arranged upside down. The telescopic end of the second electric push rod 5 is fixedly connected to a mounting seat 7. A drill 4 is arranged on one side of the lower surface of the mounting seat 7, and a display mechanism is arranged on the other side of the lower surface of the mounting seat 7.

[0020] Furthermore, the display mechanism includes a guide rod 11. The guide rod 11 is parallel to the drill rod of the drill 4. A notch adapted to the guide rod 11 is formed on the surface of the mounting seat 7. The guide rod 11 passes through the notch and forms a moving pair inside the notch. Scale lines 10 are arranged on the surface of the guide rod 11 in the vertical direction. A spring 13 is sleeved on the outer surface of the guide rod 11. The upper end of the spring 13 is fixedly connected to the upper end of the guide rod 11, and the lower end of the spring 13 is fixedly connected to the mounting seat 7. In the natural state, the spring 13 makes the lower end of the guide rod 11 flush with the drill rod of the drill 4.

[0021] It should be noted that: in the natural state, the zero scale of the scale line 10 is located at the overlapping part of the outer surface of the guide rod 11 on the upper surface of the mounting seat 7.

[0022] In this embodiment, by setting up a display mechanism, the drilling depth can be visually displayed. Specifically, during drilling, it is necessary to drive the second electric push rod 5 to extend. When the second electric push rod 5 extends, the moving states of the guide rod 11 and the drill 4 are divided into two stages. The first stage: the guide rod 11 and the drill pipe of the drill 4 synchronously follow the second electric push rod 5 to move downward. The second stage: when the lower ends of the guide rod 11 and the drill pipe contact the workpiece to be processed, the drill pipe of the drill 4 continues to move downward and simultaneously drills the workpiece. However, the guide rod 11 will stop moving due to the movement interference of the workpiece, but since the second electric push rod 5 continues to move downward and drives the mounting seat 7 to move simultaneously, therefore, the guide rod 11 will move relative to the mounting seat 7. That is, by observing the scale at the overlapping part of the guide rod 11 and the mounting seat 7, the drilling depth of the drill 4 can be obtained.

[0023] Furthermore, a sliding sleeve 8 is sleeved on the surface of the guide rod 11. The sliding sleeve 8 can move up and down on the surface of the guide rod 11. A plug rod 12 is inserted on the surface of the sliding sleeve 8. A plurality of jacks 9 are opened on the surface of the guide rod 11, and the jacks 9 are all adapted to the plug rod 12. The plug rod 12 and the jacks 9 are both arranged along the radial direction of the sliding sleeve 8, and the plug rod 12 can be moved into or out of the jacks 9.

[0024] Furthermore, the sliding sleeve 8 is of an annular structure, and the inner diameter of the sliding sleeve 8 is adapted to the outer diameter of the guide rod 11.

[0025] In this embodiment, by setting up the sliding sleeve 8, the plug rod 12 and the jacks 9 to cooperate, the drilling depth of the drill 4 can be controlled. Specifically, move the sliding sleeve 8 to the scale line 10 at the target depth, and insert the plug rod 12 into the corresponding jack 9 to fix the position of the sliding sleeve 8. When the second electric push rod 5 drives the drill pipe of the drill 4 to drill into this depth, the sliding sleeve 8 on the guide rod 11 just contacts the mounting seat 7. The sliding sleeve 8 forms a movement interference on the mounting seat 7 to prevent the mounting seat 7 from continuing to move relative to the guide rod 11, that is, to prevent the mounting seat 7 and the drill 4 from continuing to move downward, so as to achieve the purpose of controlling the drilling depth of the drill 4.

[0026] It should be noted that: the first electric push rod 3 and the second electric push rod 5 in this embodiment can both be used in combination with a controller. The controller can control when the first electric push rod 3 and the second electric push rod 5 extend and retract and the length of the extension and retraction. The controller can select a single-chip microcomputer for control. The single-chip microcomputer is composed of an arithmetic unit, a memory, an input / output device, etc., and is equivalent to a microcomputer. Compared with the general-purpose microprocessor used in a personal computer, it emphasizes more on self-supply and cost saving. Its greatest advantage is its small size and can be placed inside the instrument, but its storage capacity is small, the input / output interface is simple, and the function consumption is low. In this embodiment, the model of the single-chip microcomputer is not required. Among them, the control panel of the controller can be set on the outer surface of the vertical part of the base 1, and the user can input instructions through the control panel to control the first electric push rod 3 and the second electric push rod 5.
