Description

Technical Field

[0001] This utility model belongs to the field of lathe technology, and in particular relates to a CNC horizontal lathe that can quickly position workpieces. Background Technology

[0002] When machining shafts and bar stock on a CNC horizontal lathe, workpiece clamping and positioning is the primary and crucial step. Currently, the commonly used operating method is to use overhead cranes or other lifting equipment to hoist the workpiece to the vicinity of the machine tool chuck, where the operator manually supports and aligns it, slowly feeding it into the chuck jaws, and then clamping and fixing it in place.

[0003] The aforementioned existing technologies have the following obvious drawbacks: First, the entire process is highly dependent on the experience and skills of the operators, resulting in large fluctuations in alignment accuracy and efficiency; second, for large and heavy workpieces, manual support and adjustment are not only labor-intensive but also pose extremely high safety hazards, with accidents such as workpiece slippage and crushing injuries easily occurring; third, the repeated hoisting and adjustment process is time-consuming, seriously affecting the machine tool's uptime and production efficiency.

Detailed Implementation

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0027] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0028] This utility model embodiment provides a CNC horizontal lathe capable of quickly positioning workpieces, such as... Figures 1-4 As shown, it includes:

[0029] Lathe body 1;

[0030] Mounting plate 2 is installed on the front side wall of the lathe body 1;

[0031] A mounting rod structure is rotatably connected to the top of the mounting plate 2 at one end. An annular sleeve is fixedly installed at the other end of the mounting rod structure (the shape and size of the mounting rod structure are not limited, as long as the distance between the axis of the annular sleeve and the rotation center of the mounting rod structure is equal to the distance between the chuck axis of the lathe body 1 and the rotation center of the mounting rod structure). Multiple fourth telescopic rods 10 are fixed circumferentially at equal intervals on the annular sleeve. In this embodiment, six rods are preferred. The telescopic end of the fourth telescopic rod 10 is located inside the annular sleeve and its axis is radially along the annular sleeve.

[0032] A drive assembly used to rotate the mounting rod structure;

[0033] During operation, the distance between the axis of the annular sleeve and the chuck axis of the lathe body 1 and the rotation center of the mounting rod structure is equal.

[0034] In use, the cylindrical workpiece is inserted into the annular sleeve. Multiple fourth telescopic rods 10 extend synchronously and by the same amount, fixing the cylindrical workpiece with its axis aligned with the axis of the annular sleeve. Then, the drive assembly rotates the mounting rod structure by a set angle (the initial angle between the center of the annular sleeve, the rotation center of the mounting rod structure, and the center of the chuck). The mounting rod structure, through the annular sleeve, drives the cylindrical workpiece to rotate until the axes of the annular sleeve, the cylindrical workpiece, and the chuck are aligned. The cylindrical workpiece is then moved axially to insert one end into the chuck for fixation. This invention achieves rapid positioning and allows for the centering of the cylindrical workpiece on the ground, eliminating the need for operators to lift the workpiece to the chuck height using hoisting equipment, thus improving work efficiency.

[0035] In this embodiment, the mounting rod structure includes a first telescopic rod 7, a second telescopic rod 9, and a third telescopic rod 8. The telescopic rods can be electric or hydraulic. The fixed end of the first telescopic rod 7 is rotatably connected to the top of the mounting plate 2, and can be rotatably connected via a shaft and bearings. The movable end (i.e., the telescopic end) of the first telescopic rod 7 is hinged to the second telescopic rod 9. The annular sleeve is installed at the end of the second telescopic rod 9 away from the first telescopic rod 7. The fixed end of the second telescopic rod 9 and the movable end of the first telescopic rod 7 are connected to the third telescopic rod 8. The two ends of the third telescopic rod 8 are respectively hinged to the first telescopic rod 7 and the second telescopic rod 9. By extending or shortening the first telescopic rod 7, the second telescopic rod 9, and the third telescopic rod 8, the distance between the axis of the annular sleeve and the rotation center of the mounting rod structure can be adjusted, so that after the mounting rod structure rotates to a suitable angle, the center of the annular sleeve corresponds exactly to the center of the chuck. Meanwhile, the position of the annular sleeve can be adjusted by the coordinated extension and retraction of the first telescopic rod 7, the second telescopic rod 9, and the third telescopic rod 8. For example, when not in use, the annular sleeve can be adjusted closer to the lathe body 1 to reduce space occupation. When in use, the annular sleeve can be adjusted to the loading position to install the columnar workpiece.

[0036] In this embodiment, the driving component includes:

[0037] The worm gear 5, which is fixed to the mounting shaft of the mounting rod structure, can be fixed by welding.

[0038] The worm 6 meshes with the worm gear 5 and is fixedly connected to the output shaft of the first stepper motor 4. It can be fixedly connected by a coupling. The first stepper motor 4 is fixed on the mounting plate 2 and can be fixed by bolts.

[0039] When in operation, the first stepper motor 4 is started, which drives the worm gear 6 to rotate, the worm gear 6 drives the worm wheel 5 to rotate, and the worm wheel 5 drives the mounting rod structure to rotate.

[0040] In specific implementation, the mounting plate 2 is slidably connected to the front side wall of the lathe body 1, which can be achieved by a sliding connection of slider and groove. Multiple support wheels 15 are installed at the bottom of the mounting plate 2 to facilitate the movement of the mounting plate 2. A lead screw 3 is rotatably installed on the front side wall of the lathe body 1, which can be rotatably installed through bearings and bearing seats. The lead screw 3 passes through the mounting plate 2 and is threadedly connected to it. A second stepper motor (not shown in the figure) for driving the lead screw 3 to rotate is fixed on the front side wall of the lathe body 1, which can be fixed by bolts.

[0041] When not in use, the second stepper motor can be started to drive the lead screw 3 to rotate. The lead screw 3 will drive the mounting plate 2 to the end of the lathe body 1, so as to avoid affecting the operator's operation of the machine tool.

[0042] Preferably, the telescopic end of the fourth telescopic rod 10 is rotatably mounted with a guide wheel 11. A micro motor 14 that drives the guide wheel 11 to rotate can be fixed to the telescopic end of at least one fourth telescopic rod 10. When one end of the cylindrical workpiece needs to be fed into the chuck, the guide wheel 11 can reduce resistance and the micro motor 14 can be started to assist in making it more convenient and labor-saving.

[0043] In this embodiment, to facilitate the assembly and disassembly of the cylindrical workpiece, the annular sleeve is composed of two semicircular sleeves 13. One end of the two semicircular sleeves 13 is hinged together, and the other end of each semicircular sleeve 13 is fixed with a connecting block 12. A fifth telescopic rod 17 is fixed on one side of the connecting block 12 on one semicircular sleeve 13, which can be fixed by screws. The telescopic end of the fifth telescopic rod 17 faces the connecting block 12 and is fixed with an installation block. Two positioning pins 16 are fixed on the installation block. A positioning hole that mates with the positioning pin 16 is opened on each of the two connecting blocks 12. One semicircular sleeve 13 is fixedly connected to the installation rod structure (i.e., the end of the second telescopic rod 9 away from the first telescopic rod 7), which can be fixed by screws.

[0044] When installing a cylindrical workpiece, open the two semicircular sleeves 13, place the workpiece inside, and then close the two semicircular sleeves 13. The fifth telescopic rod 17 extends, causing the two positioning pins 16 to be inserted into the positioning holes of the two connecting blocks 12 respectively, connecting the two semicircular sleeves 13. After the chuck fixes the workpiece, the fifth telescopic rod 17 shortens, causing the two positioning pins 16 to separate from the connecting blocks 12, so that the two semicircular sleeves 13 can be separated. When the installation rod structure is reset, it can be separated from the workpiece. Of course, the fifth telescopic rod 17 can also be omitted, and manual operation is also possible without too many restrictions.

[0045] In summary, this utility model provides a CNC horizontal lathe capable of rapid workpiece positioning, the working principle of which is as follows:

[0046] Open the two semicircular sleeves 13, place the workpiece inside, and then close the two semicircular sleeves 13. The fifth telescopic rod 17 extends, driving the two positioning pins 16 to be inserted into the positioning holes of the two connecting blocks 12 respectively, connecting the two semicircular sleeves 13. The columnar workpiece is fixed by the synchronous extension of multiple fourth telescopic rods 10 with the same extension amount, and the axis of the columnar workpiece coincides with the axis of the annular sleeve. Then, the installation rod structure is driven to rotate at a set angle by the drive assembly. The installation rod structure drives the columnar workpiece to rotate through the annular sleeve until the axes of the annular sleeve, the columnar workpiece, and the chuck coincide. Then, one end of the columnar workpiece is sent into the chuck and fixed by the chuck.
