Description

Technical Field

[0001] This utility model relates to the field of boring machine technology, and in particular to a movable horizontal boring machine. Background Technology

[0002] In machining, especially in hole machining, boring tools are an indispensable finishing tool. When machining stepped holes, coaxial multi-diameter holes, or performing efficient rough boring, multiple boring heads are often mounted on the same boring bar. This multi-bladed boring bar can complete the machining of multiple dimensions in a single operation, significantly improving machining efficiency and the coaxiality of the hole system.

[0003] However, the widely used traditional multi-blade boring bar has a significant drawback: each boring head typically requires individual installation, adjustment, locking, and disassembly. Specifically, traditional bar holders have an independent tool holder, fastening screw, or locking mechanism for each head. When changing tools, setting tools, or adjusting dimensions, the operator must use tools (such as an Allen wrench) to operate each locking point individually. This process is tedious, time-consuming, and requires a high level of operator skill.

[0004] Therefore, there is an urgent need in this field for a new type of movable horizontal boring machine to solve the above-mentioned technical problems. Utility Model Content

[0009] As a further feature of this invention, the locking block is interference-fitted with the locking groove.

[0010] As a further feature of this invention, the boring bar has a square blade, and the insertion hole is a square hole that matches it.

[0011] As a further feature of this invention, the transverse feed mechanism includes a first linear guide rail and a first ball screw disposed between the slide and the machine tool, and the first ball screw is driven by a servo motor.

Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0018] A movable horizontal boring machine, reference Figures 1 to 6 The system includes a machine tool 1, a slide 2 slidably mounted on the machine tool 1, a transverse feed mechanism 3 that drives the slide 2 to move between the slide 2 and the machine tool 1, a column 4 slidably mounted on the slide 2, a longitudinal feed mechanism 5 that drives the column 4 to move between the column 4 and the slide 2, a boring head 6 that moves vertically on the column 4, and a vertical feed mechanism 7 that drives the boring head 6 to move between the column 4 and the boring head 6. Through the longitudinal feed mechanism 5, the transverse feed mechanism 3, and the vertical feed mechanism 7, the three-axis motion of the boring head (x, y, z axes) can be realized, thereby achieving precise control of the machining process.

[0019] The longitudinal, transverse, and vertical feed mechanisms have the same structure, all including linear guides and ball screws, with servo motors driving the ball screws. The servo motors drive the ball screws to rotate, thereby controlling the three-axis movement of the boring head.

[0020] The boring head 6 is equipped with a boring bar 8, which is arranged horizontally and longitudinally. Several boring tools 9 are spaced apart along the length of the boring bar 8. The boring machine in this embodiment is used to process the guide vane shaft holes of the top cover and bottom ring of the hydropower station unit. Through multiple boring tools 9, the shaft hole is processed into a stepped through hole in one pass.

[0021] To facilitate tool changing, in this embodiment, the boring bar 8 is configured as an outer rod 10 and an inner rod 11, which are rotatably arranged. The outer rod 10 is provided with an insertion hole 12 for inserting the boring bar 9. A limit block 13 is provided on the side of the boring bar 9 away from the tool head. The inner rod 11 is provided with a limit groove 14 that cooperates with the limit block 13. A locking mechanism is provided between the inner rod 11 and the outer rod 10.

[0022] The limiting block 13 is a convex block that is fixedly connected to the boring tool. The limiting groove 14 includes an annular groove that is coaxially arranged with the inner rod 11. The cross section of the annular groove is a convex groove that matches the limiting block 13. The limiting groove 14 is provided with an insertion port 15 for inserting the limiting block 13.

[0023] The locking mechanism includes a locking port 16 axially arranged along the inner wall of the outer rod 10. The size of the locking port 16 matches that of the insertion port 15. The locking port 16 and the insertion port 15 form a locking groove. A locking block 17 is inserted into the locking groove. The locking block 17 is interference-fitted with the locking groove.

[0024] The boring bar 9 has a square blade, and the insertion hole 12 is a square hole that matches it.

[0025] When replacing the boring bar 9, first remove the locking block 17 by external force. At this time, the inner rod 11 and the outer rod 10 can rotate relative to each other. Then, manually rotate the inner rod 11 so that the insertion port 15 of the inner rod 11 is aligned with the insertion hole 12 of the outer rod 10. At this time, the boring bar 9 is unlocked and can be pulled out directly. After replacing the boring bar 9, insert the boring bar 9 into the insertion hole 12 of the outer rod 10 and insert the limiting block 13 into the limiting groove 14 of the inner rod 11. Then rotate the inner rod 11 so that the insertion port 15 of the inner rod 11 is aligned with the locking port 16 of the outer rod 10 to form a locking groove. Then, insert the locking block 17 into the locking groove and apply pressure to fix it, thus completing the replacement of the boring bar 9 on the boring bar 8.
