Description

Technical Field

[0001] The utility model belongs to the technical field of automatic drilling machines, in particular to a non-standard automatic drilling machine. Background Art

[0002] A drilling machine is a general term for mechanical equipment that uses a tool that is harder and sharper than the target object to leave a cylindrical hole or hole on the target object through rotary cutting or rotary extrusion. It is also called a drilling machine, a punching machine, a drilling machine, and a through-hole machine. In the production and processing of non-standard parts, drilling machines are often required to perform automated drilling processing.

[0003] Publication No. "CN217595967U" discloses "a non-standard automated equipment for drilling". When drilling a cylindrical pipe, the pipe is placed between two clamping blocks, and the push plate is pushed downward by an electric telescopic rod, so that the drill rig fixedly installed on the lower surface of the push plate drills the pipe. While the push plate moves downward, the guide rods inserted at both ends of the push plate will abut against the inclined surface of the clamping block. The guide rods are pushed downward by a compression spring, so that the guide rods can push the two clamping blocks toward the middle, so that the V-shaped grooves opened on the adjacent sides of the two clamping blocks clamp the pipe, thereby preventing the pipe from moving when the drill rig drills a hole on the pipe surface, affecting the drilling accuracy.

[0004] The above-mentioned prior art still has the following disadvantages in the specific implementation process:

[0005] Only fixed positions of cylindrical pipes can be drilled. When drilling is required at different positions of the pipe, the placement angle of the pipe needs to be adjusted manually, which is troublesome to operate, increases the workload of the staff, and affects the drilling efficiency and progress of the pipe.

[0006] In response to the above problems, we propose a non-standard automated drilling machine. Utility Model Content

The support plate 12 is fixed on the turntable 10. The cylinder 13 is installed on the support plate 12. The telescopic end of the cylinder 13 passes through the support plate 12 and is fixedly connected to the connecting plate 14.

A second motor 26 is installed at one end of the inner side of the slide groove 2 , and the output shaft of the second motor 26 is connected to the right end of the screw rod 3 .

[0031] Example:

[0032] When in use, first place the cylindrical pipe to be drilled between the two support blocks 11, and place the pipe in the arc groove on the support block 11, then start the cylinder 13, and push the connecting plate 14 downward through the cylinder 13, thereby driving the corresponding V-shaped pressing block 15 downward to press on the top of the pipe, and combining the staggered arrangement of the V-shaped pressing block 15 and the support block 11, the purpose of pressing and fixing the two ends of the pipe is achieved;

[0033] Then, the electric push rod 6 and the drilling machine 8 are started, and the push plate 7 is pushed downward by the electric push rod 6, thereby driving the drilling machine 8 to approach the pipe. In the process of the push plate 7 being pushed downward by the electric push rod 6, the limit block 22 is driven to contact the pipe first, and the two sides of the position where the pipe needs to be drilled are pressed and fixed. Under the active cooperation of the guide rod 20 and the push plate 7, combined with the elastic effect of the spring 21, the push plate 7 continues to move downward until it drives the drilling machine 8 downward to contact the pipe, thereby realizing the drilling operation.

[0034] When it is necessary to drill holes in different parts of the pipe, the first motor 25 and the second motor 26 are started at the same time, and the second motor 26 drives the screw rod 3 to rotate. The threaded cooperation between the slider 4 and the screw rod 3, and the sliding cooperation between the slider 4 and the slide rod drive the movable frame 5 to move left and right along the direction of the screw rod 3, thereby driving the drilling machine 8 to move along the direction of the pipe, so as to facilitate drilling holes in different positions of the pipe.

[0035] Wherein, under the action of the first motor 25, the screw 17 is driven to rotate, and under the threaded cooperation between the screw 17 and the U-shaped frame 19, combined with the sliding cooperation between the guide block 24 and the guide groove 23, the U-shaped frame 19 is driven to move stably in the front-rear direction, thereby driving the rack 18 to move, and under the meshing action of the rack 18 and the gear 16, the turntable 10 is driven to rotate, and through the rotation of the turntable 10, combined with the clamping mechanism, the clamped and fixed pipe is driven to rotate, so as to achieve the purpose of adjusting the angle of the pipe, further facilitate the drilling operation at different positions of the side surface of the pipe, and no manual adjustment of the placement angle of the pipe is required, which saves time and effort and effectively improves the drilling efficiency of the pipe.

[0036] Compared with the prior art, the utility model adjusts the drilling machine 8 to move in the left and right directions through the cooperation of the screw rod 3, the slider 4 and the movable frame 5. At the same time, under the joint action of the screw rod 17, the U-shaped frame 19, the rack 18 and the gear 16, the turntable 10 is driven to rotate. Combined with the clamping mechanism, the pipe is turned over to achieve the purpose of adjusting the angle of the pipe, thereby facilitating the drilling operation at different positions on the side surface of the pipe. The problem in the prior art that only fixed positions of cylindrical pipes can be drilled and when different positions of the pipe need to be drilled, the placement angle of the pipe needs to be adjusted manually, which is cumbersome to operate, increases the workload of the staff, and affects the drilling efficiency and drilling progress of the pipe.
