Description

Technical Field

[0001] The utility model relates to the technical field of machining equipment, in particular to a two-axis boring machine. Background Art

[0002] Boring is a process in the machining process, which refers to the further processing of forged, cast or drilled pipes or workpieces. The boring process can achieve the effect of expanding the hole diameter, improving accuracy, and reducing surface roughness. It can also better correct the deviation of the original hole axis. Therefore, boring machines are often used in the machining field to process the inner holes of pipes or workpieces.

[0003] The Chinese patent with announcement number CN105855995A discloses a servo slide two-axis boring machine, including a machine tool, a workbench located in the middle of the machine tool, and two sets of power heads respectively located on the left and right sides of the machine tool. The workbench includes a workpiece clamp, a rotating structure and a sliding structure from top to bottom. When the workpiece is mounted on the workpiece clamp, the position of the workpiece can be flexibly adjusted by adjusting the rotating structure and the sliding structure, so that the power head can process the workpiece. However, the workpiece clamp in the patent is only suitable for clamping ordinary workpieces, but not for clamping pipe fittings, especially long pipe fittings, so the processing objects are relatively limited.

DETAILED DESCRIPTION

[0026] The specific implementation of the present invention is described below with reference to the accompanying drawings. In order to fully understand the present invention, many details are described below, but for those skilled in the art, the present invention can be implemented without these details.

[0027] like Figure 1As shown, a two-axis boring machine includes a machine base 1, a displacement slide 2, a boring power head 3 and a double-open vise 4. Two sections of displacement guide rails 11 are arranged above the machine base 1. Two displacement slides 2 are slidably arranged above the two sections of displacement guide rails. Two boring power heads 3 are arranged at the outer ends of the two displacement slides 2, and two double-open vises 4 are arranged at the inner ends of the two displacement slides 2, and the two double-open vises 4 together constitute a clamping mechanism for clamping a workpiece 6. Since the double-open vise 4 itself has a jaw opening adjustment function, the clamping mechanism can flexibly adapt to workpieces 6 of various widths (or diameters), and since the displacement slide 2 can flexibly adjust the spacing between the two double-open vises 4, the clamping mechanism can flexibly adapt to workpieces 6 of various lengths. It can be seen that the utility model enables the clamping mechanism of the two-axis boring machine to be widely applicable to workpieces 6 of various specifications through the mutual cooperation of the displacement slide 2 and the double-open vise 4, especially to the processing of long pipes, effectively overcoming the defects of the prior art.

[0028] like Figure 1 and Figure 2 As shown, the two-axis boring machine also includes a support seat 5, and the two support seats 5 are respectively arranged at the inner ends of the two displacement slides 2 in a movably movable manner, and the two support seats 5 together constitute a support mechanism for supporting the workpiece 6. The support mechanism can play a role in auxiliary clamping. Before processing, the workpiece 6 is hoisted and placed on the support mechanism. By adjusting the height of the support seat 5, the center of gravity of the workpiece 6 is aligned with the jaws 430 of the double-open vise 4, thereby ensuring accurate clamping; after the double-open vise 4 clamps the workpiece 6, the two support seats 5 are lowered and reset, and no longer contact the workpiece 6, thereby avoiding unnecessary wear.

[0029] like Figure 1 and Figure 2 As shown, specifically, the support seat 5 includes a support block 51, a mounting plate 52 and a support cylinder 53. The mounting plate 52 is movably arranged on the inner side of the double-open vise 4 through the support cylinder 53. The support block 51 is fixedly arranged on the mounting plate 52, and a support groove 511 for placing the workpiece 6 is arranged above the support block 51. The support seat 5 also includes a connecting block 54, a sliding sleeve 55 and a guide rod 56. One end of the connecting block 54 is fixedly connected to the double-open vise 4, and the other end of the connecting block 54 is provided with a sliding hole. The guide rod 56 is slidably installed in the sliding hole through the sliding sleeve 55, and the end of the guide rod 56 is fixedly connected to the mounting plate 52. The guide rod 56 can play a supporting and guiding role, ensuring that the support block 51 is smoothly lifted up and down to prevent rotation or shaking.

[0030] like Figures 1 to 4As shown, the double-opening vise 4 includes a vise seat 41, a clamp body 42, a clamping jaw 43 and a driving assembly; the clamp body 42 is arranged above the vise seat 41, and two clamping jaws 43 are arranged above the clamp body 42 in a reversely slidable manner through the driving assembly, and a jaw 430 for clamping a workpiece 6 is formed between the two clamping jaws 43. The double-opening vise 4 in this embodiment can flexibly adjust the size of the jaw 430 only through the driving assembly, so that it can be adapted to any specification of the workpiece 6, and has the advantages of simple structure, flexible operation, strong adaptability, etc.

[0031] like Figures 1 to 4 As shown, the driving assembly includes a vise cylinder 44 and a fork 45; the vise base 41 is provided with a mounting groove 411, the vise cylinder 44 is installed in the mounting groove 411, and the piston rod 441 of the vise cylinder 44 extends into the pliers body 42, and is provided with two fork mounting parts 442; one end of the two forks 45 is hinged to the fork mounting part 442, and the other end is hinged to the corresponding clamping jaws 43. Different from the tapered wedge transmission method of the existing double-open vise, the present embodiment uses a fork 45 to drive the two clamping jaws 43 on the pliers body 42 to perform synchronous reverse sliding action, thereby clamping or releasing the workpiece 6, improving the clamping force between the two clamping jaws 43, and preventing the clamped workpiece 6 from swinging during the processing, resulting in inaccurate processing.

[0032] like Figures 1 to 4 As shown, specifically, the clamping jaw 43 includes a slider 431, a jaw seat 432 and a clamping plate 433; a slide rail is provided above the clamp body 42, the slider 431 is slidably arranged on the slide rail, and a hinge groove 434 adapted to the fork 45 is provided at the bottom of the slider 431; the jaw seat 432 is fixed above the slider 431, and a clamping plate 433 is provided on the inner side of the jaw seat 432, and a jaw 430 is formed between the two clamping plates 433. In addition, a rotating shaft 451 is provided in the middle of the two forks 45, and an axial hole adapted to the rotating shaft 451 is provided in the clamp body 42, and the two forks 45 are pivotally connected to the clamp body 42 through the rotating shaft 451 and the axial hole. The design of the rotating shaft 451 can play a fulcrum role, ensuring that the two forks 45 rotate smoothly around it, thereby achieving uniform opening and closing action, and then driving the slider 431 to achieve synchronous reverse sliding.

[0033] like Figure 1 As shown, a feed guide rail 21 is provided above the displacement slide 2, and the boring power head 3 is slidably arranged on the feed guide rail 21 through the feed slide 22. The distance between the boring power head 3 and the double-open vise 4 can be flexibly adjusted through the feed slide 22, so that the boring power head 3 can accurately process the workpiece 6.

[0034] like Figure 1As shown, the machine base 1 is provided with collecting grooves 12 on both sides of the displacement guide rail 11 , and a discharge hopper 13 is provided at the end of the collecting groove 12 , thereby facilitating the collection of debris and waste liquid generated during the processing, thereby reducing the difficulty of cleaning the machine base 1 .

[0035] like Figure 1 As shown, the boring power head 3 in this example is preferably a servo boring and spreading tool head, and the specific structure and working principle of the servo boring and spreading tool head belong to the prior art and are not described in detail here. In addition, the displacement slide 2 and the feed slide 22 in this embodiment are both driven by a screw slide, and their working principle is also the prior art, so they are not described in detail. Those skilled in the art can refer to the above description for specific understanding and implementation.

[0036] The above is only a specific implementation method of the utility model, but the design concept of the utility model is not limited to this. Any non-substantial changes to the utility model using this concept shall be deemed as an infringement of the protection scope of the utility model.
