Technical Field

[0001] The invention relates to the field of machining, in particular to a machine tool. Background Art

[0002] Machine tools refer to machines used to manufacture machines. They are generally divided into metal cutting machine tools, forging machine tools, and woodworking machine tools. In modern machinery manufacturing, all parts with high precision requirements and fine surface roughness requirements generally need to be processed by cutting on machine tools. Lathes are machine tools that mainly use turning tools to turn rotating workpieces. Drills, reamer drills, reamers, taps, dies, and knurling tools can also be used on lathes for corresponding processing. Lathes are mainly used to process shafts, discs, sleeves, and other workpieces with rotating surfaces. They are the most widely used type of machine tools in machinery manufacturing and repair factories.

[0003] When processing parts, it is sometimes necessary to drill holes in the parts. However, some parts have irregular shapes, and existing drilling machines cannot fix such parts, resulting in the inability to guarantee processing quality. Summary of the invention

[0004] The purpose of the present invention is to provide a machine tool which can clamp and fix parts of any shape and perform drilling processing.

[0005] The purpose of the present invention is achieved through the following technical solutions:

[0009] Each of the tightening strips is provided with a through hole, a cross bar is connected in the through hole, and support arms are connected at both ends of the cross bar. The support arms extend toward the center of the rotating ring to form a lifting support for the lower end of the tightening part of the tightening strip.

[0010] A screw rod IV is rotatably arranged on each of the tightening strips, and the screw rod IV is threadedly connected with the cross bar.

[0011] Both ends of each cross bar are provided with supporting pins, and a block is connected inside the supporting arm. The block rotates on the supporting pin so that the supporting arm can be rotated to a vertical state and folded, and both ends of each cross bar are provided with baffles so that the supporting arm can be tightly pressed against the baffle when supporting the parts in a horizontal state.

[0032] like Figure 1-11 As shown, the machine tool is described in detail:

[0033] A machine tool comprises a circular ring seat 101, and an arm plate 102 fixed on the outer side of the circular ring seat 101, a limit tube 103 is fixed on the arm plate 102, a sliding column 104 is lifted and slid in the limit tube 103, a screw rod Ⅰ106 is passed through and rotated on the arm plate 102, the screw rod Ⅰ106 is threadedly connected to the sliding column 104, a cross arm seat 107 is connected to the upper end of the sliding column 104, a drill bit 108 is installed on the cross arm seat 107, a rotating ring 201 is connected inside the circular ring seat 101, a plurality of seat plates 202 are fixed circumferentially on the rotating ring 201, a square tube 301 is passed through and slidably on each seat plate 202, a top tightening strip 303 is fixed to each square tube 301 near the central end of the rotating ring 201, a screw rod Ⅱ302 is rotated on each top tightening strip 303, and each screw Ⅱ302 is threadedly connected to the corresponding seat plate 202.

[0034] When in use, the part to be drilled is placed in the rotating ring 201, and then the multiple screw rods II 302 are rotated respectively to make the multiple screw rods II 302 move toward the part on the corresponding base plate 202, and then the multiple tightening strips 303 are brought close to the part and tighten the part, thereby fixing the part in the rotating ring 201. Since the positions of the multiple tightening strips 303 are controlled by the corresponding screw rods II 302 respectively, the machine tool can adapt to the fixation of parts of any shape and size; after the part is fixed, the drill bit 108 is started to rotate, and the screw rod I 106 is rotated at the same time, so that the threaded transmission slide column 104 can be lowered in the limiting tube 103, thereby driving the drill bit 108 to descend and contact the part, completing the drilling process of the part.

[0035] like Figure 1-11 As shown:

[0036] The rotating ring 201 is rotatably connected to the circular ring seat 101, the upper end of the sliding column 104 is fixed with a limit frame 105, the cross arm seat 107 penetrates and slides in the limit frame 105, and a screw III 109 is rotated on the limit frame 105, and the screw III 109 is threadedly connected to the cross arm seat 107.

[0037] By driving the rotating ring 201 through the first motor installed on the circular ring seat 101, the parts can be driven to rotate. At the same time, the screw III 109 can be rotated to thread the limit frame 105, so that the cross arm seat 107 slides in the limit frame 105, thereby driving the drill bit 108 to move radially along the rotating ring 201. In conjunction with the rotation of the rotating ring 201, drilling can be performed on any position of the fixed parts in the rotating ring 201, thereby improving the processing efficiency.

[0038] Further:

[0039] Each of the tightening strips 303 is semicircular near the center of the rotating ring 201 .

[0040] As a result, the tightening strip 303 contacts the component at a semicircular portion, thereby being able to tighten and fix the component better.

[0041] like Figure 1-11 As shown:

[0042] Each of the tightening strips 303 is provided with a through hole 304, a cross bar 401 is connected in the through hole 304, and support arms 405 are connected at both ends of the cross bar 401. The support arms 405 extend toward the center of the rotating ring 201 to form a lifting support for the lower end of the tightening part of the tightening strip 303.

[0043] By providing the support arm 405, the part can be lifted and supported at the lower end of the part when the part is clamped and fixed, thereby further ensuring the stability of the part fixation.

[0044] like Figure 1-11 As shown:

[0045] A screw rod IV 406 is rotatably mounted on each of the tightening strips 303 , and the screw rod IV 406 is threadedly connected to the cross bar 401 .

[0046] By rotating the screw IV 406, the cross bar 401 can be threadedly driven to make the cross bar 401 rise and fall in the through hole 304, thereby adjusting the height of the support arm 405, thereby adapting to the auxiliary lifting support of parts of different thicknesses, and at the same time adapting to the lifting support of different thickness parts of the same part.

[0047] like Figure 1-11 As shown:

[0048] Both ends of each cross bar 401 are provided with support pins 403, and a block 404 is connected inside the support arm 405. The block 404 rotates on the support pin 403, so that the support arm 405 can be rotated to a vertical state and folded, and both ends of each cross bar 401 are provided with a baffle 402, so that the support arm 405 can be tightly pressed against the baffle 402 when supporting parts in a horizontal state.

[0049] By setting the support pin 403 and the block 404, the support arm 405 can be rotated so that the support arm 405 can be rotated to a vertical state on the support pin 403 through the block 404, thereby forming a retracted support arm 405; by setting the baffle 402, when the support arm 405 lifts and supports the part, the other end of the support arm 405 presses against the baffle 402 to ensure that the support arm 405 can lift and support the part.

[0050] Further:

[0051] The support arm 405 is provided with a long hole for damping the sliding of the block 404, which is used to control the length of the support arm 405 extending out of the tightening strip 303.

[0052] By pushing the support arm 405 so that the support arm 405 slides on the block 404 through the long hole, the length of the support arm 405 extending out of the tightening strip 303 can be controlled to facilitate supporting parts of different shapes.

[0053] like Figure 1-11 As shown:

[0054] An auxiliary block 501 is slidably arranged in each of the square tubes 301, a C-shaped plate 502 is rotatably arranged on the upper end of each of the auxiliary blocks 501, auxiliary strips 503 are fixed at both ends of each of the C-shaped plates 502, the two auxiliary strips 503 are respectively located on both sides of the tightening strip 303, and a screw rod V305 is rotatably arranged in each of the square tubes 301, and the screw rod V305 is threadedly connected to the auxiliary block 501.

[0055] By rotating the screw rod V305, the auxiliary block 501 can be threadedly driven to slide in the square tube 301, and then the C-shaped plate 502 can be driven to move. When the parts are clamped and fixed, the C-shaped plate 502 again clamps the parts on both sides of the clamping strip 303 through the two auxiliary strips 503, thereby forming auxiliary clamping of the parts, further ensuring the clamping and fixing of the parts;

[0056] At the same time, by rotating the C-shaped plate 502 on the auxiliary block 501, the two auxiliary bars 503 can adapt to and assist in clamping parts of different shapes;

[0057] Further:

[0058] The auxiliary strip 503 is cylindrical.

[0059] Further:

[0060] Four legs are fixed circumferentially at the lower end of the annular seat 101 .
