Description

Technical Field

[0001] The present application relates to the technical field of horizontal machining, and in particular to a horizontal boring machine with a U-axis tool. Background Art

[0002] The flat turntable is also called the U-axis tool. The U-axis generally refers to the axis parallel to the X-axis of the machine tool. The U-axis tool can be numerically controlled to change diameter in real time in the U-axis direction. U-axis tools are usually used in horizontal boring and milling machines, floor-standing boring machines, machining centers with telescopic axis functions, and various special machine tools.

[0003] The patent with announcement number CN218695995U discloses a feed flat rotary disc that is convenient for tool disassembly and replacement. By setting a flexible valve, the translation seat can push the flexible valve to the two ends of the adjustment groove when it slides in the adjustment groove, so as to prevent the adjustment groove from hindering the movement of the translation seat. When the translation seat slides away from this position, the flexible valve pushed to the two ends will reset due to its own elasticity and cover the inside of the adjustment groove again, thereby preventing the waste generated by the processing from flying into the adjustment groove and affecting the normal operation of the ball screw 1. When the translation seat slides, the flexible valve will be in an open state at the translation seat. At this time, the processing waste will enter the adjustment groove through the opening of the flexible valve, thereby causing the accumulation of processing waste in the adjustment groove, affecting the rotation of the ball screw 1. Utility Model Content

[0004] The purpose of this application is to address the above-mentioned problems existing in the prior art and to propose a horizontal boring machine with a U-axis tool.

[0005] The present application can be implemented through the following technical scheme: a horizontal boring machine with a U-axis tool, comprising a frame and a fixture installed on the frame and used to fix the workpiece, the frame is provided with a U-axis tool that can contact the workpiece, the U-axis tool comprises a base detachably mounted on the frame, a rotating seat rotatably mounted on the base and provided with a slide groove, a motor 1 that drives the rotating seat to rotate, a processing seat slidably connected to the slide groove, an electric push rod 1 installed on the processing seat, a tool head seat installed on the telescopic end of the electric push rod 1, a cutting tool installed on the tool head seat, a lead screw 1 rotatably mounted on the rotating seat and threadedly connected to the processing seat, and a motor 2 that drives the lead screw 1 to rotate so that the processing seat slides along the length direction of the slide groove, the cutting tool can contact the workpiece clamped by the fixture, and the processing seat is sleeved with a shielding sheet, which can slide with the processing seat and can always cover the slide groove.

[0006] In the above technical solution, the motor 1 can drive the rotating seat to rotate, and the rotation of the rotating seat can drive the cutting tool to rotate in a circle in the vertical plane, thereby performing a cutting operation on the workpiece clamped by the fixture. By setting the motor 2 to drive the lead screw 1 to rotate, the rotation radius of the cutting tool can be adjusted. By setting the electric push rod 1, the distance from the cutting tool to the base can be adjusted, so that the cutting tool can adapt to the cutting requirements of different positions of the workpiece. The shielding sheet can slide along the length direction of the slide slot and can always cover the slide slot, thereby shielding the slide slot, thereby reducing the possibility of cutting debris flying into the slide slot and affecting the rotation of the lead screw 1.

[0007] Furthermore, the shielding sheet includes a sheet body and a rubber ring installed on the sheet body, the sheet body is penetrated by a hole, the rubber ring is installed on the inner wall of the hole, and the processing seat is provided with a ring groove for embedding the rubber ring.

[0008] In the above technical solution, the rubber ring is elastic, and the rubber ring can be fixed in position relative to the processing seat by inserting the shielding sheet into the ring groove, so the installation is convenient.

[0009] Furthermore, the sheet body is soft, and a through hole is formed on the rotating seat and on a side of the slide groove close to the base, and the through hole is used for the sheet body to pass through, and the sheet body is connected end to end.

[0010] In the above technical solution, the sheets are connected at the ends and can be passed through the through holes. Compared with sheets made of hard materials, this design saves space.

[0011] Furthermore, the cutter head seat is connected to the cutting tool via bolts.

[0012] In the above technical solution, the cutting tool will be worn after being used for a period of time. The cutting tool and the cutter head seat are connected by bolts to facilitate the replacement of the cutting tool.

[0013] Furthermore, a limiting block is formed on the tool, an embedding groove for embedding the cutting tool is provided on the tool head seat, a limiting groove is provided on the inner wall of the embedding groove, and the limiting block can be slidably connected to the limiting groove.

[0014] In the above technical solution, after the limit block slides into the limit groove, the angle of the cutting tool relative to the cutter head seat is determined, and then the cutter head seat and the cutting tool are connected by bolts. This design ensures that after the old cutting tool is removed, the position of the new cutting tool relative to the cutter head seat remains unchanged.

[0015] Furthermore, a hanging rope is installed on the cutting tool.

[0016] In the above technical solution, when workers need to collect the replaced cutting tools of multiple devices in the factory, the hanging rope makes it convenient for the workers to take multiple cutting tools at the same time.

[0017] Furthermore, it also includes a shaping sleeve, which has a penetration hole. The penetration hole is used for the telescopic end of the electric push rod 1 to penetrate and the shaping sleeve can be sleeved on the electric push rod 1. The hole wall of the penetration hole can contact the telescopic end of the electric push rod 1. Two mounting blocks are provided at the fixed end of the electric push rod 1. Two electric push rods 2 are installed on the mounting blocks. The telescopic direction of the two electric push rods 2 is consistent with the telescopic direction of the electric push rod 1. The two electric push rods 2 are used to drive the shaping sleeve to move linearly along the telescopic direction of the telescopic end of the electric push rod 1.

[0018] In the above technical solution, the hole wall of the drilled hole can contact the telescopic end of the electric push rod one. After the telescopic end of the electric push rod one is extended, the shaping sleeve is driven by the electric push rod two to move linearly with the telescopic end of the electric push rod one, thereby shaping the telescopic end of the electric push rod one, reducing the possibility of bending and deformation during cutting by the cutting tool.

[0019] Furthermore, a mounting plate is formed on the mounting block, and the mounting plate is connected to the fixed end of the electric push rod through a plurality of screws.

[0020] In the above technical solution, the mounting plate is mounted on the electric push rod by means of screws 1, so that the position of the mounting block is fixed.

[0021] In summary, the present application has the following technical effects: Motor 1 can drive the rotating seat to rotate, and the rotation of the rotating seat can drive the cutting tool to rotate in a circle in the vertical plane, thereby performing a cutting operation on the workpiece clamped by the fixture. By setting Motor 2 to drive Screw 1 to rotate, the rotation radius of the cutting tool can be adjusted. By setting Electric Push Rod 1, the distance from the cutting tool to the base can be adjusted, so that the cutting tool can adapt to the cutting requirements of different positions of the workpiece. The shielding sheet can slide along the length direction of the slide slot and can always cover the slide slot, thereby shielding the slide slot, thereby reducing the possibility of cutting debris flying into the slide slot and affecting the rotation of Screw 1.
