Technical Field

[0001] This utility model relates to the field of machining technology, specifically a drilling, tapping and milling machine for round bars. Background Technology

[0002] In the field of machining, the machining processes are very extensive. Due to the different structures of various parts, the required equipment varies. In existing technology, two types of equipment are typically used for machining: one is ordinary machine tools combined with specific tooling fixtures, and the other is specially designed machinery.

[0003] However, the existing technology has the following drawbacks:

[0004] Traditional machining methods often use multiple independent machines to complete drilling, tapping, and milling processes separately. This machining mode has many drawbacks, such as large machine footprint, requiring a significant investment in multiple machines, increasing production costs; and the transfer of round bar parts between different machines can easily cause collisions and damage to the parts, affecting product quality; at the same time, multi-machine machining mode requires a lot of manual operation, resulting in low production efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a round bar drilling, tapping, and milling machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a round bar drilling, tapping, and milling machine, comprising a frame, a milling assembly, a movable drilling and tapping assembly, and a lifting and transferring assembly. The milling assembly is provided on both sides of the front end of the top of the frame, and the movable drilling and tapping assembly is provided on both sides of the rear end of the top of the frame. Two vertical first guide rails are symmetrically arranged in the middle of the top of the frame. The bottom sides of the lifting and transferring assembly are slidably mounted on the top of the first guide rails via electric sliders. A water tank and a receiving assembly are arranged sequentially in the middle of the back of the frame. A feeding rack is fixedly installed in the middle of the front end of the top of the frame, and a human-machine mechanism is fixedly installed on one side of the front end of the top of the frame via a support rod.

[0007] Using the above technical solution, the lifting and transfer component can drive the round bar to move, so that it can be processed by the milling component and the movable drilling and tapping component in sequence, and then unloaded and stored by the receiving group.

[0008] The lifting and transfer assembly includes a transfer base plate and a lifting seat. Linear bearings are fixedly installed at the four corners of the top of the lifting seat, and guide rods are inserted inside the linear bearings. Lifting cylinders are fixedly installed at the middle of both ends of the top of the lifting seat, and the movable ends of the lifting cylinders are fixedly connected to the middle of both ends of the bottom of the transfer base plate.

[0009] Using the above technical solution, the lifting cylinder can drive the transfer top plate to rise, and the guide rod moves up and down inside the linear bearing to adjust the height of the transfer base plate, thereby moving the round bar.

[0010] A transfer cylinder is fixedly installed in the middle of the bottom of the lifting seat. Limiting blocks are provided at both ends of the first guide rail. Four transfer support blocks are evenly distributed on the top of the transfer base plate, and V-shaped slots are provided at both ends of the transfer support blocks.

The bottom of the base is slidably mounted on the top of the second guide rails via a slider. A first hydraulic clamp and a second hydraulic clamp are fixedly mounted at both ends of one side of the top of the base, respectively. A tapping body and a drilling body are fixedly mounted at both ends of the other side of the top of the base via parallel clamps, respectively.

A round bar can complete multiple processing steps after being clamped once, reducing the transfer time of parts between different machines and greatly improving processing efficiency. One machine replaces multiple independent machines, reducing equipment purchase costs and equipment floor space. At the same time, the increased automation reduces manual operation and lowers labor costs. Attached Figure Description
