Description

Technical Field

[0001] The present invention relates to the technical field of drilling equipment, and specifically discloses a drilling device for aluminum alloy door and window frame profiles. Background Art

[0002] During the production and preparation of aluminum alloy doors and windows, in order to facilitate the installation and connection of hinges and locks, it is necessary to use drilling equipment to punch holes in the frame profiles before assembling the aluminum alloy doors and windows. The traditional method of punching holes in aluminum alloy door and window frame profiles still uses a bench drill for punching. During the punching process, not only tools are needed to clamp the profiles, but also the frame profiles often need to be punched on two adjacent vertical surfaces. At this time, the profiles need to be rotated and adjusted again, clamped and fixed, and then drilled, which greatly affects the punching efficiency of the profiles.

[0003] The utility model patent with the application number 2022200611931 discloses a profile processing drilling device, including a bottom frame. An insertion slot is opened on the inner wall of one side of the bottom frame, and a receiving frame is slidably inserted into the inner wall of the insertion slot. A handle is fixedly connected to one side surface of the receiving frame. The receiving frame is located inside the bottom frame, and a receiving groove is opened on the top of the bottom frame. A quick clamping mechanism is arranged on the top of the bottom frame. The quick clamping mechanism includes guide rails, and the bottoms of the two guide rails are fixedly connected to the top of the bottom frame. The profile processing drilling device disclosed in this patent can quickly install and clamp the profiles when drilling the profiles through the setting of the quick clamping mechanism. After the profiles are clamped and fixed, the punching operation is carried out. Although it can ensure the stability during the punching process, the frame profiles of aluminum alloy doors and windows often need to be punched on two vertically connected side surfaces. At this time, the operator needs to rotate and adjust the profiles, and then press and fix them again after adjustment; the workload is large and the punching efficiency of the aluminum alloy door and window frame profiles is seriously affected during the whole process, which cannot meet the requirements of batch and high-efficiency production of aluminum alloy doors and windows. Based on this, the present application proposes a drilling device for aluminum alloy door and window frame profiles that can effectively solve the above technical problems. Summary of the Invention

[0004] The present invention aims to provide a drilling device for aluminum alloy door and window frame profiles to solve the above-mentioned deficiencies existing in the existing profile processing drilling device when punching the aluminum alloy door and window frame profiles.

[0005] The present invention is achieved through the following technical solutions:

[0006] A drilling device for aluminum alloy door and window frame profiles, including a processing machine table, a drilling processing unit, and a feeding unit. The drilling processing unit is arranged on the processing machine table, and a clamping and rotating mechanism is arranged on the processing machine table between the feeding unit and the drilling processing unit;

[0007] Among them, the clamping and rotating mechanism includes two symmetrically arranged rotating support seats, and circular rotating blocks are respectively rotatably connected to the two rotating support seats, and a right-angle notch is opened on the outer circumferential surface of the circular rotating block, and a clamping plate is arranged in the right-angle notch, and connecting rods are arranged at both ends of the clamping plate, and the connecting rod is L-shaped and the inner end is arranged toward the center of the circular rotating block. The two connecting rods are respectively located on both sides of the circular rotating block, and guide sleeves acting on the connecting rods are fixed on both side surfaces of the circular rotating block, and a spring is arranged between the guide sleeve and the connecting rod, and cam blocks are fixed on the rotating support seats on both sides of the circular rotating block, and the inner end of the connecting rod is provided with an abutment wheel acting on the cam block.

[0008] As a further setting of the above scheme, the cam block is composed of a small arc segment, a large arc segment and a connecting arc segment. The small arc segment takes the horizontal line toward the feeding unit as the starting point and the vertical upward point as the ending point, and the center of the small arc segment and the large arc segment coincides with the center of the circular rotating block.

[0009] As a further configuration of the above scheme, the drilling processing unit includes a moving seat and a first cylinder for realizing the forward and backward movement of the moving seat, a second cylinder is arranged at the top of the moving seat, the lower end of the piston rod of the second cylinder is connected to a lifting platform, and a plurality of drilling components are arranged on the lifting platform.

[0010] As a further configuration of the above scheme, a strip-shaped opening is provided on the lifting platform, and a plurality of the drilling assemblies are adjustable along the direction of the strip-shaped opening.

[0011] As a further configuration of the above scheme, the processing machine is provided with a third slide rail and a bidirectional adjustment screw rod which are parallel to each other, the rotating support seat is slidably arranged on the third slide rail, and the rotating support seat is also provided with a screw nut block which matches the bidirectional adjustment screw rod.

[0012] As a further configuration of the above scheme, a hollow tube rotatably connected to the rotating support seat is concentrically arranged on the circular rotating block, a driving shaft penetrating the hollow tube is arranged on the processing machine, a fastener acting on the driving shaft is arranged on the hollow tube, and a driving assembly for realizing the rotation of the driving shaft is arranged on the processing machine.

[0013] As a further configuration of the above scheme, the feeding unit includes a conveying seat connected to the front end of the processing machine, and a plurality of conveying belts arranged side by side are arranged in the conveying seat. A plurality of material fixing blocks are arranged at equal intervals on the outer surface of the conveying belt, and the material fixing blocks on the conveying belt are arranged one by one.

[0014] As a further configuration of the above scheme, a material discharging conveying trough is provided on the upper surface of the processing machine table between the clamping rotating mechanism and the drilling processing unit, and a material discharging conveying belt is provided in the material discharging conveying trough.

[0015] When the drilling device disclosed in the present invention drills the aluminum alloy door and window frame profiles, the operator places the cut-to-length profiles one by one in the feeding unit, and then the profiles are sent to the clamping and rotating mechanism one by one under the action of the conveyor belt.

[0016] At this time, the right-angle notch rotates to the lower side of the horizontal position (refer to the attached Figure 8 ), and due to the action of the cam block on the abutting wheel, the clamping plate and the connecting rod can be moved and opened, and then the profiles conveyed on the feeding unit can smoothly enter between the clamping plate and the right-angle notch.

[0017] Subsequently, the circular rotating block rotates 90° clockwise. During the rotation of the circular rotating block, under the action of the spring, the cam block and the abutting wheel, the clamping plate will gradually move towards the center of the circle, thereby clamping and fixing the profile (refer to the attached Figure 7 ). After fixing, the drilling processing unit is started to drill the profile. After the profile drilling is completed, the circular rotating block continues to rotate 90° clockwise. At this time, the profile is still in the clamped state, and after the processing surface of the profile is switched, the profile is drilled again.

[0018] Finally, after the profile drilling is completed, the circular rotating block continues to rotate 90° clockwise. During the rotation of the circular rotating block, due to the action of the cam block on the abutting wheel and the action of the spring, the clamping plate can be gradually opened until finally the profile falls onto the discharge conveyor belt under its own gravity, and the profile is sent out of the processing machine by the discharge conveyor belt. Beneficial effects

[0019] Through the design of the clamping and rotating mechanism, the aluminum alloy door and window frame profile drilling device disclosed in the present invention can automatically rotate and clamp the profile after loading. After the profile is clamped and fixed, the drilling component first drills on one side surface, and then after rotating 90°, the other side surface can be drilled. After the drilling is completed, the clamping effect on the pipe can be automatically released during the continuous rotation, and the automatic feeding, drilling, switching of the processing surface and automatic discharging of the pipe can be realized during the whole drilling process of the pipe; the whole drilling device realizes the whole process of automatic feeding, drilling, switching of the processing surface and automatic discharging during the drilling process of the pipe. Without setting a clamping device composed of driving parts such as cylinders, the stability of the drilling process can be maintained. It has a high degree of automation, high processing efficiency and excellent use effect.

[0020] When the aluminum alloy door and window frame profile drilling device disclosed in the present invention drills profiles with different drilling requirements, it can conveniently and quickly adjust the positions of the drilling component and the clamping and rotating mechanism to meet the drilling requirements of various profiles, and has better applicability.
