Description

Technical Field

[0001] This application relates to the field of machining technology, and in particular to a drilling device for machining. Background Technology

[0002] In the field of machining, drilling is a common processing step, widely used in the processing of materials such as metals and plastics. Currently, most common drilling devices employ a drilling machine combined with a three-axis feed system to achieve precise workpiece positioning and drilling. These devices typically include a power source, gearbox, and spindle assembly mounted on the drilling machine, using a drill bit on the spindle to perform the drilling operation. However, traditional drilling devices often rely on the operator's experience and judgment for drill bit positioning before drilling, lacking a precise positioning calibration mechanism. This makes it difficult to guarantee drilling accuracy, especially in high-precision machining applications. Most drilling devices rely on manual operation during drill bit positioning and calibration, which is not only inefficient but also susceptible to human error, increasing the risk of machining errors. Utility Model Content

[0003] To address the problem that traditional drilling devices lack a precise positioning calibration mechanism for the drill bit before drilling, which makes it difficult to guarantee drilling accuracy, this application provides a drilling device for machining.

[0004] The drilling device for machining provided in this application adopts the following technical solution:

[0005] A drilling device for machining includes a head, a spindle is provided on the head, a drill bit is detachably provided at the lower end of the spindle, and a positioning component is provided on the outer side of the spindle.

[0006] The positioning assembly includes a guide sleeve mounted on the spindle, the guide sleeve being hinged with several positioning forks, and the positioning forks being equipped with positioning units for determining whether the drill bit is positioned on the central axis of the spindle.

[0007] Preferably, the spindle includes a drive cutter shaft that is drivenly connected to the output shaft of the machine head, the drive cutter shaft is provided with a housing on its outer side, and the drill bit is mounted on the drive cutter shaft.

[0008] Preferably, the guide sleeve is slidably fitted onto the outer shell and can move up and down along the outer shell. The outer shell is slidably fitted with a telescopic spring, which is located inside the machine head and the guide sleeve.

[0009] Preferably, the positioning unit includes a micro switch disposed on the guide sleeve, the micro switch being located at the upper end of the positioning fork.

[0010] Preferably, the machine head is also equipped with an alarm, which is used to provide an alarm when the positioning fork triggers the micro switch.

[0011] In summary, this application includes the following beneficial technical effects:

[0012] By using the spindle, drill bit, positioning assembly, and alarm in conjunction, the positioning fork contacts the rod or pipe. If the drill bit is not aligned with the central axis of the rod or pipe, the positioning fork deflects, and the alarm does not activate. At this time, the operator can adjust the position of the machine head and the drill bit. When the drill bit is aligned with the central axis of the rod or pipe, the positioning fork remains vertically downward under the action of gravity, causing the positioning fork to trigger the micro switch. At this time, the alarm will activate to alert the operator. Compared with existing technologies, this method has the advantages of simple structure and convenient operation.

Detailed Implementation

[0017] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0018] This application discloses a drilling device for machining. (Refer to...) Figure 1-3 A drilling device for machining includes a connector 6 installed at the movable end of the three-axis feed system of a drilling machine. A machine head 1 is installed at the lower end of the connector 6. The machine head 1 includes a gearbox 102 installed on the connector 6. A power motor 101 is installed at the input end of the gearbox 102. A spindle 2 is installed at the output end of the gearbox 102. A drill bit 3 is detachably mounted on the spindle 2. When the power motor 101 is started, the spindle 2 drives the drill bit 3 to work through the transmission of the gearbox 102, thereby drilling a hole in the workpiece.

[0019] Reference Figure 3The main shaft 2 includes a housing 202 mounted on the housing of the gearbox 102. The output end of the gearbox 102 is connected to a transmission cutter shaft 201. The transmission cutter shaft 201 is rotatably mounted inside the transmission cutter shaft 201. The housing 202 can be made of a hollow polygonal rod. The housing 202 provides protection for the transmission cutter shaft 201 and can also guide the positioning assembly 4.

[0020] Reference Figure 3 A positioning component 4 is installed on the outer casing 202. The positioning component 4 includes a guide sleeve 401 slidably installed on the outer casing 202. The guide sleeve 401 includes two connecting sleeves 4011. Both ends of the two connecting sleeves 4011 are provided with screw holes, and bolts 4012 are installed on the screw holes to allow the guide sleeve 401 to be disassembled and replaced. Several positioning forks 402 are hinged on the connecting sleeves 4011. A telescopic spring 404 is slidably fitted on the outer casing 202. The telescopic spring 404 is located inside the head 1 and the guide sleeve 401. The telescopic spring 404 provides elastic support to the guide sleeve 401, which can ensure that the positioning forks 402 will not interfere with the drilling depth of the drill bit 3 when drilling.

[0021] Reference Figure 2 The positioning fork 402 adopts a Y-shaped structure. One of the support arms of the positioning fork 402 is equipped with a rotating port. The screw is slidably installed inside the rotating port. One end of the screw is welded to the connecting sleeve 4011, and the other end is threaded with a nut. The nut limits the positioning fork 402 to prevent it from falling off. When not in use, it can also be disassembled.

[0022] A positioning unit is installed on the positioning fork 402. The positioning unit detects whether the positioning fork 402 is in a state of natural downward gravity, and then determines whether the drill bit 3 is in the central axis position of the spindle 2.

[0023] Reference Figure 2 The positioning unit can use appropriate sensors, touch switches, etc. as needed, such as micro switch 403 installed on guide sleeve 401. Micro switch 403 is located at the upper end of positioning fork 402. Alarm 5 is also installed on machine head 1. Micro switch 403 and alarm 5 are connected in series and connected to external power supply unit, such as storage battery.

[0024] The implementation principle of a drilling device for machining according to an embodiment of this application is as follows:

[0025] The drilling device for machining is installed on the moving end of the three-axis feed system of the drilling machine via connector 6. Before starting the system, the drill bit is positioned and calibrated using positioning component 4. Specifically, positioning fork 402 is hinged to guide sleeve 401 via the support arm in its Y-shaped structure and fixed by screws and nuts. Under the action of gravity, positioning fork 402 hangs down naturally. At this time, micro switch 403 detects its status. If it is in the preset position (i.e., the state of natural hanging by gravity), it indicates that drill bit 3 is located on the central axis of spindle 2, and drilling accuracy is guaranteed.

[0026] If the micro switch 403 is not triggered, it indicates that the drill bit position is off. The drill bit 3 needs to be adjusted until the micro switch 403 is correctly triggered and the alarm 5 is triggered to issue an alarm to remind the operator.

[0027] During drilling, the positioning fork 402, under the elastic support of the telescopic spring 404, maintains slight pressure on the drill bit 3 without interfering with its drilling depth, thus ensuring the verticality and accuracy of the drilling.

[0028] After drilling is complete, turn off the power motor 101 and disconnect the power supply unit. Clean the drilling device and workpiece of debris and impurities, and keep the equipment clean. Inspect all parts for wear or damage, and replace or repair them if necessary.
