[0002] Mechanical parts, also known as mechanical components, are the basic elements that make up machinery. They are inseparable individual parts that make up machinery and machines. Machining mechanical parts requires the use of lathes. A lathe is a machine tool that mainly uses a cutting tool to turn rotating workpieces.

[0003] For example, Chinese utility model patent application number 202120866356.9 discloses an adjustable lathe for machining mechanical parts, including a lathe for machining mechanical parts. The surface of the lathe is provided with a sliding door, and the surface of the sliding door has an observation window. The observation window has an internal glass. The surface of the sliding door is provided with an adjustable dustproof plate, and the surface of the sliding door has symmetrically formed grooves relative to the bottom of the observation window. Slider blocks are symmetrically fixed on the inner side of the adjustable dustproof plate, and the sliders are slidably connected to the grooves. The surface of the sliders has symmetrically formed guide grooves. This utility model, through the design of the adjustable dustproof plate, allows the adjustable dustproof plate to cover the observation window for dust protection when the observation window is not in use. Then, the adjustable dustproof plate is fixed by a limiting screw. Compared with the existing technology, this effectively prevents dust from falling onto the internal glass.

[0004] When using the aforementioned patent for machining, workers need to move the workpiece to be processed onto the machining table. Since the machining table is located inside the machine tool and its structure is relatively fixed and not easy to move out, and the internal space of the machine tool is relatively small, it is inconvenient to place large workpieces when machining them. In addition, the machining table is quite high, and the transportation process is time-consuming and laborious, which needs to be improved. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1-5 This utility model provides an adjustable machining lathe: it includes a lathe body 1, a push assembly at the bottom of the lathe body 1, the push assembly includes a hydraulic cylinder 2 fixedly installed at the bottom of the lathe body 1, a rectangular block 3 fixedly connected to the telescopic end of the hydraulic cylinder 2, two guide rods 4 fixedly connected to the front of the inner wall of the lathe body 1, and the rectangular block 3 movably sleeved on the outer surface of the two guide rods 4, a base 5 fixedly connected to the top of the rectangular block 3, a drive assembly inside the base 5, a lifting plate 6 above the base 5, a lifting assembly for adjusting the height of the lifting plate 6 between the bottom of the lifting plate 6 and the top of the base 5, movable wheels 20 at the four corners of the bottom of the base 5, a worktable 21 fixedly installed on the top of the lifting plate 6, and a fixture (not shown in the figure) for clamping and fixing the workpiece on the worktable 21;

[0033] By using the hydraulic cylinder 2, guide rod 4, rectangular block 3 and moving wheel 20 in combination, the worktable 21 can be pushed out from inside the lathe body 1 during loading, avoiding the need to place workpieces inside the cramped lathe body 1, making it easier to load large workpieces and improving the lathe's applicability.

[0034] The drive assembly includes a drive motor 7 fixedly installed on the inner wall of the base 5 and two mounting plates 8. The two mounting plates 8 are located on both sides of the bottom of the inner wall of the base 5. Two first threaded rods 9 and two second threaded rods 10 are rotatably installed between the two mounting plates 8. One end of the first threaded rod 9 is fixedly connected to a first gear 11, and one end of the second threaded rod 10 is fixedly connected to a second gear 12 that meshes with the first gear 11. The ends of the two first threaded rods 9 away from the first gear 11 are both fixedly connected to synchronous transmission wheels 13. A synchronous transmission belt 14 is connected between the outer surfaces of the two synchronous transmission wheels 13.

[0035] The synchronous transmission wheel 13 and the synchronous transmission belt 14 are configured to rotate synchronously, thereby ensuring that all components of the drive assembly can operate synchronously.

[0036] The output end of the drive motor 7 is fixedly connected to one of the first gears 11.

[0037] The lifting assembly includes two first sliders 15 and two second sliders 16 that are slidably installed on the bottom of the inner wall of the base 5. The top of the first slider 15 is hinged to a first support rod 17, and the top of the second slider 16 is hinged to a second support rod 18. The ends of the two first support rods 17 away from the first sliders 15 are rotatably connected to the bottom right side of the lifting plate 6, and the ends of the two second support rods 18 away from the second sliders 16 are rotatably connected to the bottom left side of the lifting plate 6.

[0038] By using the drive assembly, lifting assembly and guide plate 19 together, the height of the worktable 21 can be adjusted. When it is necessary to place the workpiece to be processed on the worktable 21, the worktable 21 can be adjusted to a suitable height first, which reduces the handling distance of the workers, reduces the workload of the workers, shortens the loading and unloading time, and improves the processing efficiency of the lathe.

[0039] Two first sliders 15 are threaded onto the outer surfaces of two first threaded rods 9, and two second sliders 16 are threaded onto the outer surfaces of two second threaded rods 10.

[0040] Guide plates 19 are fixedly installed on the top of the base 5 and on both sides of the lifting plate 6, and the lifting plate 6 is slidably installed between the two guide plates 19.

[0041] Working principle: When machining is required, the operator first starts the hydraulic cylinder 2. The telescopic end of the hydraulic cylinder 2 extends, which drives the rectangular block 3 to move and the base 5 to move outward, thereby pushing the moving wheel 20 to roll, pushing the guide plate 19 and the lifting plate 6 to move outward, and then causing the worktable 21 to move outward. After the worktable 21 moves outside the lathe body 1, the hydraulic cylinder 2 is turned off. The guide rod 4 can guide the moving rectangular block 3 and improve the stability of the worktable 21 when it moves back and forth.

[0042] Then the drive motor 7 is started. The output end of the drive motor 7 rotates counterclockwise, driving the first gear 11 and the first threaded rod 9, which are fixedly connected to its output end, to rotate. Under the transmission action of the synchronous transmission belt 14 and the synchronous transmission wheel 13, the other first threaded rod 9 and the first gear 11 rotate synchronously. Under the meshing action of the first gear 11 and the second gear 12, the two second gears 12 rotate, driving the two second threaded rods 10 to rotate synchronously.

[0043] Meanwhile, under the limiting effect of the base 5 on the two first sliders 15 and the two second sliders 16, the first slider 15 moves to the left and the second slider 16 moves to the right, causing the first support rod 17 and the second support rod 18 to descend near the end of the lifting plate 6, thereby causing the lifting plate 6 and the worktable 21 to descend. During this process, the limiting effect of the guide plate 19 on the lifting plate 6 improves the stability of the lifting plate 6 during the downward movement.

[0044] After lowering the lifting plate 6 to a suitable height according to the worker's height and the size and weight of the workpiece to be processed, the drive motor 7 is turned off. The worker then moves the workpiece to be processed onto the worktable 21 and fixes it with a clamp (not shown in the figure). Then, the drive motor 7 is started, and the output end of the drive motor 7 rotates clockwise, indirectly driving the worktable 21 to rise. At the same time, the hydraulic cylinder 2 is started, and the telescopic end of the hydraulic cylinder 2 retracts, indirectly driving the worktable 21 to move into the lathe body 1. After the worktable 21 moves to the working area, the drive motor 7 and the hydraulic cylinder 2 are turned off. Then, the workpiece is processed by the lathe body 1. The lathe body 1 adopts existing mature technology, and its specific structure and principle will not be elaborated in detail here.

[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
