Description

Technical Field

[0001] This utility model relates to the field of compressor pipe processing, and in particular to a drilling device for processing compressor pipes. Background Technology

[0002] Compressor fittings are assemblies used to connect and support various pipes and components in a compressor system. They play a vital role in the installation, operation, and maintenance of compressor equipment. Compressor fittings are generally made of high-strength metal materials to ensure reliability and durability under high pressure, low temperature, or extreme operating conditions. Drilling is one of the key processes in the manufacturing of compressor fittings, used to create connection holes, mounting holes, or fluid passages on the fittings.

[0003] According to Chinese Patent No. CN218109410U, a drilling device for processing compressor three-tube fittings includes a frame, on which a limiting frame is fixedly installed. The bottom surface of the limiting frame is set as a concave arc surface. First through holes are opened at both ends of the limiting frame, and second through holes are opened on both sides of the limiting frame. Two spaced side plates are fixedly installed at the bottom of the limiting frame, and friction wheels are provided in the two side plates. In the above patent solution, when clamping the fittings, a cylinder is inserted inside the fitting for support to avoid clamping deformation. However, the fittings of the compression molding machine have different diameters, and the cylinder is not easy to adapt to fittings of different diameters, requiring frequent replacement, which leads to inconvenience in use. Therefore, we propose a drilling device for processing compressor fittings to solve the above problems. Summary of the Invention

[0004] The purpose of this utility model is to provide a drilling device for processing compressor pipe fittings, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A drilling device for processing compressor pipe fittings includes a fixed shell. Two sets of support rods are fixedly connected to the upper surface of the fixed shell. The top ends of the two sets of support rods are fixedly connected to a positioning mechanism. A drilling mechanism is installed inside the positioning mechanism. Two support plates are provided inside the fixed shell. An adjustment mechanism is installed on one side of the fixed shell. Two cylinders are installed on the outer surface of the fixed shell. The output end of each cylinder passes through the fixed shell and is fitted with a clamping plate. Anti-slip pads are fixedly connected to the sides of the two clamping plates that are close to each other.

[0006] In a further embodiment, the positioning mechanism includes a positioning frame, the interior of which is slidably connected to a sliding plate via a groove, and a first electric push rod is installed on the inner wall of the positioning frame, the output end of which is connected to one side of the sliding plate.

[0007] In a further embodiment, the drilling mechanism includes a sliding opening on the upper surface of the sliding plate, a drilling frame slidably connected inside the sliding opening, a second electric push rod installed on the inner wall of the drilling frame, the output end of each second electric push rod being connected to the upper surface of the sliding plate, a second motor installed inside the drilling frame, and a drill bit installed on the output end of the second motor.

[0008] In a further embodiment, the adjustment mechanism includes a housing fixed to the outer surface of the fixed shell. A first motor is mounted on the outer surface of the housing. One end of each of the two support plates passes through the housing and extends into the interior of the housing. A limiting groove is formed in the inner wall of the housing. One end of each support plate is slidably connected to the limiting groove. A threaded sleeve is fixedly embedded on the outer surface of each support plate. The two threaded sleeves are connected to a positive and negative lead screw by common threads. The outer surfaces of both ends of the positive and negative lead screw are connected to the housing through bearings. One end of the positive and negative lead screw is connected to the output end of the first motor.

[0009] In a further embodiment, the interior of the fixed shell is provided with a support plate, and two third electric push rods are installed on the bottom surface of the fixed shell. The output end of each third electric push rod passes through the fixed shell and is connected to the bottom surface of the support plate.

[0010] In a further embodiment, two support seats are fixedly connected to the bottom surface of the fixed shell, and a controller is installed on the front surface of the fixed shell.

[0011] Compared with the prior art, the beneficial effects of this utility model are: This device uses a cylinder-driven clamping plate in conjunction with an anti-slip pad to achieve bidirectional clamping of pipe fittings, adapting to pipe fittings of different diameters. It eliminates the need for frequent clamp changes, significantly improving processing efficiency. The adjustment mechanism uses a first motor to drive forward and reverse lead screws to synchronously adjust the spacing of the support plates, further adapting to different pipe diameter requirements. Adjusting the support plates supports the inner wall of the pipe fitting, and the clamping plate causes deformation of the pipe fitting during clamping. The positioning mechanism uses a first electric push rod to control the sliding plate to move along the groove, combined with the second electric push rod of the drilling mechanism to adjust the drill bit position. The controller centrally controls the operation of the cylinder, electric push rod, and motor, achieving full automation of clamping, positioning, and drilling processes, reducing manual intervention and lowering operational difficulty.

The positioning mechanism 4 includes a positioning frame 401. A sliding plate 403 is slidably connected inside the positioning frame 401 through a sliding groove 404. A first electric push rod 402 is installed on the inner wall of the positioning frame 401. The output end of the first electric push rod 402 is connected to one side of the sliding plate 403. The positioning mechanism 4 uses the first electric push rod 402 to control the sliding plate 403 to move along the sliding groove 404.
