Description

Technical Field

[0001] The utility model relates to the technical field of lathe tools, in particular to a square turret lathe tool which is easy to disassemble and assemble. Background Art

[0002] A lathe is a machine tool that mainly uses a turning tool to turn a rotating workpiece. Lathes are the most important type of metal cutting machine tools. In general machine manufacturing factories, lathes are the most numerous and are also called machine tools. Drills, reamer drills, reamers, taps, dies and knurling tools can also be used on lathes for corresponding processing. The function of a lathe is to perform cutting processing on rotating surfaces of various sizes and shapes, as well as spiral surfaces.

[0003] The square turret lathe tool is a commonly used tool in mechanical processing, which is used for cutting, turning and other operations on the workpiece. After searching, the Chinese patent application number is: CN202123107649.8, which discloses a square turret for heavy cutting on a horizontal bed, including a base, a lower seat body is arranged at the top of the base, a driving motor is installed on one side of the base, and an upper seat body is arranged at the top of the lower seat body. The square turret for heavy cutting on the horizontal bed is provided with a limited position slide, a micro motor, a threaded sleeve and a threaded rod. When the height of the tool needs to be adjusted, the micro motor is started, and the micro motor drives the threaded rod to rotate. Since the threaded rod and the threaded sleeve cooperate with each other, the rotation of the threaded rod will cause the threaded sleeve to rise and fall, and the lifting of the threaded sleeve can drive the tool to rise and fall, so that the tool lifting can facilitate the tool tip to align with the lathe spindle axis. By aligning the tool tip with the lathe spindle axis, the tool tip can be prevented from being higher or lower than the spindle axis to affect the processing accuracy and surface quality, which solves the problem that it is inconvenient to adjust the height of the tool and it is easy to affect the processing accuracy and surface quality.

[0004] The above technical solution and the traditional turret have the same defect, that is, the tool does not have the function of quick disassembly and assembly. Both the installation and disassembly of the tool require a lot of time, which is not only time-consuming and labor-intensive, but also affects the production efficiency of the lathe. Therefore, we need to propose a square turret lathe tool that is easy to disassemble and assemble. Utility Model Content

[0029] See also Figure 1-4 , the utility model provides a technical solution:

[0030] A square turret 2 lathe tool 3 that is easy to disassemble and assemble, comprising a main structure;

[0031] The main structure includes a base 1 and a turret 2 mounted on the base 1, and a tool 3 is fixed on the turret 2;

[0032] It includes a fixing mechanism arranged on the turret 2 for fixing the tool 3;

[0033] The fixing mechanism includes a fixing screw 8 threadedly installed on the upper layer of the turret 2 and a pressure plate 9 rotatably installed at the lower end of the fixing screw 8. Positioning rods 11 are symmetrically arranged at the bottom of the pressure plate 9. A hole 20 for the positioning rod 11 to pass through is opened on the tool 3.

The lower end of the fixing screw 8 is inserted and fixed to the inner ring of the bearing of the bearing seat 10. A hexagonal head 17 is welded to the upper end of the fixing screw 8.

[0034] By setting up a main structure including a base 1, a turret 2 and a tool 3, a fixing mechanism including a fixing screw 8 and a pressure plate 9 is set on the turret 2 to fix the tool 3 on the turret 2, a hexagonal head 17 is set at the upper end of the fixing screw 8, and the lower end is rotatably installed with a pressure plate 9 with a positioning rod 11 through a bearing seat 10, a hole 20 is correspondingly provided at the tail end of the tool 3, and a positioning hole 14 is correspondingly provided at the lower layer of the turret 2. The device has a simple structure and is easy to use. The tool 3 is fixed by thread locking and positioning matching to ensure a firm and reliable connection between the turret 2 and the tool 3. At the same time, the tool 3 can be quickly installed and disassembled, which saves time and effort and improves the production and processing efficiency of the lathe.

[0035] During specific use, the rocker arm 18 with the hexagonal head 19 is sleeved on the hexagonal head 17 at the upper end of the fixed screw 8 and rotated, so that the fixed screw 8 can drive the pressure plate 9 to move up and down, thereby quickly installing and disassembling the tool 3. The pressure plate 9 is pressed against the tool 3, and the positioning rod 11 passes through the hole 20 on the tool 3 and is inserted into the positioning hole 14 of the lower layer of the turret 2, so that the connection between the tool 3 and the turret 2 is more reliable.

[0036] Among them, a fixing screw hole 13 corresponding to the fixing screw 8 is opened on the upper layer of the turret 2 between the two groups of guide holes 15.

[0037] The hexagonal head 17 on the upper end of the fixing screw 8 and the hexagonal head 17 on the limiting block 21 have the same specifications and are both adapted to the hexagonal head 19 on the rocker arm 18 .

[0038] For further information, see Figure 2-3 :

[0039] Two sets of guide rods 12 are symmetrically welded on both sides of the fixing screw 8 at the top of the pressure plate 9 . A guide hole 15 is opened on the upper layer of the turret 2 . The guide rods 12 are slidably inserted into the guide hole 15 .

[0040] By arranging a guide rod 12 on the pressure plate 9 and slidingly inserting the guide rod 12 into the guide hole 15 on the turret 2, during the up and down displacement of the pressure plate 9, it can be ensured that the motion trajectory is on the same straight line, thereby ensuring the accuracy of positioning the tool 3.

[0041] See also Figure 5-8 In order to facilitate tool change during lathe processing, this application makes the following design:

[0042] It also includes a connecting mechanism for connecting the turret 2 and the base 1.

In actual use, the connecting screw 16 is raised by the rocker arm 18 in cooperation with the hexagonal head 17 until the limit block 21 is away from the turret 2, at which time the turret 2 can be rotated to change the tool; after the tool change is completed, the rocker arm 18 is rotated to move the connecting screw 16 downward until the limit block 21 is pressed against the surface of the turret 2 to lock it.

[0045] See also Figure 5-6 In order to improve the connectivity between the turret 2 and the base 1 and avoid displacement and deflection of the turret 2 during lathe processing, the present application makes the following design:

[0046] A plurality of groups of slide blocks 6 are disposed around the bottom of the turret 2 , and the edges of the slide blocks 6 are designed to be smooth. A plurality of groups of slide grooves 7 adapted to the slide blocks 6 are disposed around the top of the base 1 .

[0047] There are multiple groups of sliders 6 arranged around the bottom of the turret 2, and the edges of the sliders 6 are smoothly arranged. A corresponding slide groove 7 is provided on the base 1. When the turret 2 is rotated, the slider 6 leaves the current slide groove 7 and enters the next slide groove 7, which is not only labor-saving, but also, after the tool change is completed, when the slider 6 stops in the current slide groove 7 to lock the turret 2, the slider 6 and the slide groove 7 can cooperate to play a locking and positioning role, thereby avoiding displacement and deflection of the turret 2 during lathe processing.
