Description

Technical Field

[0001] This utility model relates to the field of special machine tool technology, and in particular to a rotary single-sided multi-drill machine tool. Background Technology

[0002] A valve drilling machine is a tool used to drill holes in pipes or containers. It is primarily used when installing valves, flanges, or other pipe connections, requiring holes to be made at the valve joints. These machines typically consist of a drill bit, a drilling machine, and a guide device. The drill bit, usually made of carbide, is used to cut the pipe wall and can be selected in different diameters and shapes as needed. The drilling machine is used to drive the drill bit to rotate. It can be a handheld electric drill or a larger mechanical device. The guide device ensures the drill bit is in the correct position for drilling; it typically includes clamps, guide rails, or guide arms, and is used when drilling three-way valves.

[0003] During the valve drilling process, multiple flange holes are usually opened on at least two end faces; therefore, the position of the valve workpiece needs to be adjusted manually, and the valve workpiece needs to be frequently disassembled, which affects drilling efficiency and is not conducive to rapid factory production. Utility Model Content

[0009] A translational feed mechanism is mounted on the worktable, and the spindle box is adjusted to slide on the slide rail;

[0010] A rotary table is set on the workbench and located at one end of the slide rail, with a workpiece placed at its upper limit.

[0011] In this embodiment, the bottom of the spindle box is provided with a limiting mechanism adapted to the slide rail, and the spindle box is also provided with a main motor that drives the multi-axis drill bit.

[0012] In this embodiment, the translational feeding mechanism is one of the following: a feed cylinder, a lead screw transmission mechanism, a pneumatic cylinder, or an electric telescopic cylinder, which is mounted on the worktable.

[0013] In this embodiment, the rotary table further includes a rotary support disposed on the worktable and a rotary seat rotatably disposed on the rotary support; the rotary seat is provided with a slot that is adapted to and limits the outer wall of the workpiece; and the rotary seat is provided with a positioning mechanism for positioning the workpiece.

[0014] In this embodiment, the positioning mechanism further includes two guide posts vertically arranged on the rotating seat, a clamping member vertically arranged on the guide posts, and a locking member for adjusting the position and height of the clamping member on the guide posts.

[0015] Furthermore, in this embodiment, a positioning groove is provided at the bottom of the end side of the rotary table, an upwardly adjustable telescopic cylinder is provided on the side wall of the worktable, and a positioning pin that is adapted to be inserted into the positioning groove is provided at the telescopic end.

[0016] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0017] This invention relates to a one-time clamping system for drilling valves of sizes DN400 to DN600. It can process double-sided flange holes and center threaded bottom holes in the valve body. Rapid die changing with a multi-axis drill bit group allows for simultaneous drilling of flange holes (10-24 holes or more can be drilled simultaneously to meet customer product requirements). Furthermore, this application utilizes a rotary table and positioning mechanism to achieve rapid workpiece position adjustment and positioning, thereby improving drilling efficiency.
