[0002] Boring refers to the further processing of forged, cast or drilled holes. Boring can enlarge the hole diameter, improve accuracy and reduce surface roughness. Since the boring assembly usually includes a motor and a transmission part, its own weight is relatively large, and it needs to be displaced in the vertical direction when the boring tool is boring vertically. Therefore, the boring assembly needs to be installed on a vertical slide rail. Due to its large deadweight, when the power assembly drives it, especially when pushing it upward, it needs to provide a large thrust. In order to ensure its accurate movement, the cost is greatly increased when selecting the power part. In order to solve the above technical problems, the utility model provides an installation mechanism for a boring assembly, and a counterweight is arranged on the other side of the boring assembly to balance the deadweight of the boring assembly, thereby ensuring control accuracy while reducing the cost of accessories.

DETAILED DESCRIPTION

[0022] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0023] like Figure 1 , Figure 2 , Figure 3 As shown, a mounting mechanism of a boring assembly includes a bracket 3, a boring assembly, and a counterweight 2. Two second slide rails 13 parallel to each other are mounted on the front side of the bracket 3, and two first slide rails 14 parallel to each other are mounted on the rear side of the bracket 3. The first slide rail 14 is vertically downward, and the first slide rail 14 is parallel to the second slide rail 13. A slide plate 11 is slidably connected to the second slide rail 13, and a power assembly is connected to the slide plate 11. The power assembly is used to push the slide plate 11 to move. Specifically, the power assembly includes a second motor 9 and a screw rod 10. The second motor 9 is fixedly mounted on the front side of the bracket 3. The two ends of the screw rod 10 are rotatably connected to the screw rod frame. The screw rod frame is fixed to the front side of the bracket 3, and the output shaft of the second motor 9 is connected to one end of the screw rod 10. A screw rod sleeve 12 is fixed on the slide plate 11, and the screw rod sleeve 12 is sleeved on the outside of the screw rod 10. When the second motor 9 rotates, it drives the screw rod 10 to rotate, thereby driving the screw rod sleeve 12 and the slide plate 11 to move along the second slide rail 13.

[0024] The boring assembly is mounted on the slide plate 11. Specifically, the boring assembly includes a first motor 1, a transmission unit, and a spindle. The spindle and the transmission unit are mounted inside the spindle mounting frame 6. A boring tool clamping unit 7 is mounted at the lower end of the spindle. A boring tool is fixedly clamped on the boring tool clamping unit 7. A transmission unit is connected between the first motor 1 and the spindle. When the first motor 1 rotates, the transmission unit drives the spindle to rotate, thereby driving the boring tool to rotate to bore holes.

[0025] The counterweight 2 is slidably connected to the first slide rail 14. The top of the bracket 3 is provided with a U-shaped groove 33, which is suitable for reducing weight and saving materials. Two sets of sprocket frames 4 are fixedly installed on the top of the bracket 3, and the two sprocket frames 4 are installed on both sides of the top of the U-shaped groove 33. Sprockets 5 are rotatably installed at both ends of each sprocket frame 4. Two chains are connected between the counterweight 2 and the slide plate 11. Each chain corresponds to a sprocket frame 4, and the chain is engaged with the sprockets 5 at both ends of the sprocket frame 4. The sum of the weights of the boring assembly and the slide plate 11 is equivalent to the weight of the counterweight 2, so as to ensure that the power assembly is not affected by the deadweight of the boring assembly and the slide plate 11, so that the selection requirements of the power assembly are reduced, thereby reducing the cost. A limit frame 8 is provided on the lower side of the counterweight 2, and the limit frame 8 is fixed on the rear side of the bracket 3 to prevent the counterweight 2 from falling after the chain breaks accidentally.

[0026] like Figure 4 , Figure 5 , Figure 6 As shown, the bracket 3 includes a bracket body 32 and two legs 31. The bracket body 32 is located on the upper side of the two legs 31, and the bracket body 32 and the two legs 31 are an integrally formed structure. Among them, the position below the bracket body 32 between the two legs 31 is used to install a horizontal boring assembly, which can be bored in the vertical direction and the horizontal direction at the same time. In order to reduce weight and save materials, the interior of the bracket body 32 is provided with a plurality of mutually parallel horizontal plates, a plurality of mutually parallel longitudinal plates, and a plurality of mutually parallel vertical plates. The horizontal plates, longitudinal plates, and vertical plates intersect vertically, and a plurality of weight-reducing holes 34 are provided on the horizontal plates, longitudinal plates, and vertical plates, which reduce weight while also ensuring support strength.
