[0002] The horizontal milling and boring machine is a highly automated universal machine tool. Through significant improvements, it features an advanced structure and superior performance. It can perform drilling, boring, reaming, countersinking, milling, grooving, and threading operations on workpieces, making it a key piece of equipment for machining box-shaped parts. The overall layout of the machine tool is a single column, side-mounted box, and fixed rotary table. The worktable moves longitudinally and laterally on the bed. The machine tool possesses excellent rigidity, usability, and a large machining range.

[0003] For example, patent publication number CN106112048A discloses a CNC horizontal boring machine, in which the slide of the milling head is slidably connected to the column through only two slide rails. However, since the milling head of the boring machine is relatively long, due to the mechanical principle, it is easy to cause the machine to shake when moving up and down due to uneven force, resulting in insufficient stability when the milling head moves.

[0004] In view of this, the applicant conducted in-depth research on the above-mentioned issues, which led to this case. Summary of the Invention

[0005] The main purpose of this invention is to provide a highly stable horizontal boring machine column, which can effectively improve the stability of the milling head during movement.

Detailed Implementation

[0021] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0022] like Figure 1-4 As shown, a high-stability horizontal boring machine column includes a column 1, a slide 2, an adapter 3, and sliders 4. The milling head is connected to the slide 2. Rectangular guide rails 11 are symmetrically arranged on the side wall of the column 1, and a roller rail 12 is located behind the column 1. Both the rectangular guide rails 11 and the roller rail 12 extend vertically. The side wall of the slide 2 has grooves that mate with the rectangular guide rails 11. Two sliders 4 are connected to the side wall of the slide 2 via the adapter 3, and the sliders 4 are slidably connected to the roller rails 12.

[0023] In this embodiment, the adapter 3 includes a locking block 31 and an adapter block 32. The locking block 31 is locked and fixed to the side of the slide block 2, and the side wall of the locking block 31 can cooperate with the side wall of the rectangular track to abut against it, thereby playing a limiting role. The adapter block 32 is locked and connected to the slide block 2, and the slider 4 is locked and fixed to the adapter block 32. The adapter block 32 includes a longitudinal connecting part and a transverse connecting part, which are perpendicularly connected. The side walls of the longitudinal connecting part and the transverse connecting part are provided with reinforcing ribs. The longitudinal connecting part is fixedly connected to the side of the locking block 31, and the transverse connecting part is fixedly connected to the slider 4. With the above structure, the connection between the slider 4 and the slide block 2 is more secure, making it easier to disassemble and maintain the slide block 2.

[0024] In this embodiment, the slide block 2 has a first scraper 51 on the side wall of the slide groove, and a first scraper 52 is provided on the first scraper 51. The locking block 31 has a second scraper 61, and a second scraper 62 is provided on the second scraper 61. With the above structure, the first scraper 52 and the second scraper 62 can scrape away impurities on the rectangular track during the sliding process, making the rectangular track and the slide groove cooperate more smoothly and steadily, and further improving the stability of the slide block 2's lifting and lowering.

[0025] In this embodiment, a motor 71 is provided at the upper end of the column 1. The power output end of the motor 71 is connected to a lead screw 72, which is rotatably connected to the column 1 and threadedly connected to the slide block 2. The motor 71 drives the lead screw 72 to rotate, thereby driving the slide block 2 to move up and down.

[0026] In this embodiment, a counterweight frame 81 is provided at the upper end of the column 1. The counterweight frame 81 has several through holes 811, and a connecting shaft 82 is provided on each through hole 811. A first counterweight block 83 is sleeved on the connecting shaft 82. The front-to-back distance of the first counterweight block 83 can be adjusted through the connecting shaft 82. A counterweight cylinder 84 is provided at the rear end of the column 1. A second counterweight block 85 is provided on the piston rod of the counterweight cylinder 84. The piston rod is driven to rise and fall by the counterweight cylinder 84, thereby adjusting the horizontal height of the second counterweight block 85.

[0027] Compared with existing technologies, the advantages of this invention are that it guides the slide block 2 using two guide rails and one roller rail 12, increasing the contact area between the slide block 2 and the column 1. This results in a more uniform force distribution on the slide block 2 and smoother sliding. Furthermore, this invention also includes a first counterweight 83 at the upper end of the column 1 and a second counterweight 85 on the rear side wall of the column 1, adjusting the overall mass distribution of the column 1 to achieve static or dynamic balance, thereby further improving stability and safety.
