Description

Technical Field

[0001] The utility model relates to the technical field of drill bits, in particular to a drill bit guide device component. Background Art

[0002] At present, when a machine tool uses a drill bit for drilling processing, the drill bit part extends out of the drill rod box, and the drill rod part remains in the box and is supported by the support sleeves at the front and rear ends of the box. At this time, the drill bit is in a suspended state. Before drilling, the drill bit must first process a bottom hole on the end face of the workpiece as a guide hole, and continue to process forward along this guide hole. When processing the guide hole, the suspended drill bit will shake when processing the hole because there are no restrictions on the surroundings. In this way, the positioning accuracy of the bottom hole cannot be guaranteed. If processing continues along the trajectory of this bottom hole, the accuracy of the entire hole will be in error.

[0003] After searching, a Chinese patent discloses a drill guide device (authorization announcement number CN206153629U), which includes a drill bit, a drill rod box and a drill rod. The drill bit is on the drill rod, and a guide sleeve is arranged at the front end of the drill rod box. The inner hole diameter of the guide sleeve is greater than or equal to the diameter of the drill bit. The rear end of the drill rod box is provided with a supporting sleeve that can support the drill rod. The drill rod can move back and forth in the drill rod box. The drill rod is installed in the drill rod box through the supporting sleeve and the guide sleeve. Although this patented technology can effectively improve the processing accuracy of drilling, it has a simple structure and is easy to install and maintain.

[0004] However, the above device still has some shortcomings in actual use. The most obvious one is that in the prior art, when the drill bit is far away from the workpiece to be processed, the drill rod and the drill bit need to be extended out of the drill rod box. Since the prior art drill rod is not provided with any guide structure during the suspension process, the front end of the drill rod vibrates strongly during drilling, which can easily cause the drilling position to shift, thereby affecting the drilling effect of the workpiece. Utility Model Content

[0005] In view of the problem in the prior art: in the prior art, when the drill bit is far away from the workpiece to be processed, the drill rod and the drill bit need to be extended out of the drill rod box. Since the existing drill rod is not provided with any guiding structure during the suspension process, the front end of the drill rod vibrates strongly during drilling, which easily causes the drilling position to shift, thereby affecting the drilling effect of the workpiece. The main purpose of the utility model is to provide a drill guide device assembly.

[0006] The technical solution of the utility model is as follows: a drill guide device assembly comprises a mounting base, a rotating shaft is arranged at the top of the mounting base, one end of the rotating shaft is fixedly connected to a drill body, two fixed plates are fixedly connected to the top of the mounting base, a bearing is arranged on the outer side of the rotating shaft, a guide plate is fixedly installed on the outer side of the bearing, both sides of the guide plate are fixedly connected to fixed blocks, the interior of the fixed blocks are fixedly connected to limiting rods, the limiting rods are slidably connected to the corresponding fixing plates, and the end of the limiting rod away from the fixed block is fixedly connected to a limiting member.

[0007] By adopting the above technical solution, through the coordinated use of the fixed block, the limit rod and the fixed plate, an important guiding role can be played on the rotating shaft and the drill body, so that the drill body has a certain stability during the drilling process and is not prone to deviation, thereby improving the drilling effect of the workpiece.

[0008] As a preferred embodiment, a movable groove is opened at the bottom end of the inner wall of the mounting base, and a support plate is slidably connected to the inside of the movable groove. The bottom of the support plate is fixedly connected to a limiting strip, one end of the support plate extends to the outside of the mounting base, and the support plate is fixedly connected to the guide plate.

[0009] By adopting the above technical solution and arranging the support plate and the limit strip, the stability of the rotating shaft and the drill body during drilling can be further enhanced.

[0010] As a preferred embodiment, a slide groove is opened at the top of the inner wall of the mounting base, a slider is slidably connected inside the slide groove, a servo motor is fixedly installed at the top of the slider, and the output shaft of the servo motor is fixedly connected to the rotating shaft.

[0011] By adopting the above technical solution and setting a servo motor, the rotation of the rotating shaft can be driven, and then the rotation of the drill body can be achieved.

[0012] As a preferred embodiment, two cylinders are fixedly mounted on the top of the mounting base and are located on both sides of the servo motor, a moving plate is fixedly connected between the piston rods of the two cylinders, and the moving plate is fixedly connected to the servo motor.

[0013] By adopting the above technical solution, the movable plate can be driven to move by the contraction of the piston rod of the cylinder, thereby shortening the processing distance between the drill body and the workpiece.

[0014] As a preferred implementation, mounting plates are fixedly connected to both sides of the mounting base, and two mounting holes are provided inside the mounting plates.

[0015] By adopting the above technical solution, the drill guide device assembly can be installed on the corresponding machine tool using bolts through the coordinated use of the mounting hole and the mounting plate.

[0016] As a preferred implementation, the servo motor and the cylinder are both electrically connected to an external control device, and a non-slip layer is fixedly connected to the bottom of the mounting base, and the non-slip layer is made of rubber.

[0017] By adopting the above technical solution, the start and stop of the servo motor and the cylinder can be controlled by an external control device, and the friction coefficient between the drill guide device and the machine tool can be increased by setting an anti-skid layer.

[0018] Compared with the prior art, the advantages and positive effects of the utility model are:

[0019] In the utility model, when the rotating shaft and the drill body are extended and drilling is carried out, the bearing and the guide plate will be driven to move, and at the same time, the fixed block and the limit rod will be driven to move, so that the limit rod can slide in the corresponding fixed plate. The coordinated use of the fixed block, the limit rod and the fixed plate can play an important guiding role for the rotating shaft and the drill body, so that the drill body has a certain stability during the drilling process and is not prone to deviation, thereby improving the drilling effect of the workpiece, and the setting of the limit piece can play an important limiting role for the limit rod.
