[0002] A lathe is a machine tool mainly used for turning a rotating workpiece with a turning tool. A lathe is the most important cutting machine tool among metal cutting machine tools. In general machine manufacturing factories, lathes are the most numerous and are also called mother machines. On a lathe, drills, reamers, broaches, taps, threading dies, knurling tools, etc. can also be used for corresponding processing. The function of a lathe is to perform cutting processing on various rotating surfaces and helical surfaces with different sizes and shapes.
[0003] In terms of structural composition, an existing lathe generally includes a headstock, a feed box, a carriage, a tool post, a tailstock, a bed, etc. When the lathe is in a working state, with the cooperation of the above-mentioned various mechanisms, the turning tool on the tool post performs a controllable displacement relative to the part to be processed to perform a cutting operation on the part to be processed;
[0004] However, the tool post structure of the existing lathe is relatively simple. Generally, a positioning screw that can move up and down is used to fix the tool on the tool post. Moreover, the number of tools that the existing tool post can install is small (generally four), which cannot meet the processing requirements of relatively complex workpieces and urgently needs to be improved. Summary of the Utility Model

[0028] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.
[0029] Please refer to Figure 1 Now, the installation structure of the turning tool provided by the present utility model will be described. Generally speaking, the present utility model mainly expands the number of tool heads installed on the tool rest by changing the existing tool rest into a tool disc 11, improves the applicable range of the lathe for the parts to be processed, and thus improves the working efficiency of the lathe.
[0030] Based on the above design concept, the installation structure of the turning tool in the present utility model mainly includes a first mounting bracket 1 and a second mounting bracket 2. Among them, the first mounting bracket 1 includes a tool disc 11 and a mounting handle 12 arranged coaxially. The tool disc 11 is installed at one end of the mounting handle 12. And, in order to make the structure of the tool disc 11 adaptable to lathe machining, in this embodiment, the axis of the mounting handle 12 is parallel to the lathe spindle, and the mounting handle 12 can drive the tool disc 11 to rotate around its own axis. A plurality of turning tools are provided on the outer periphery of the tool disc 11; the second mounting bracket 2 includes a drive shaft 21 and a mounting box 22. The drive shaft 21 and the mounting handle 12 are both rotatably arranged in the mounting box 22. The drive shaft 21 is used to drive the mounting handle 12 to rotate around its own axis, and the axis of the drive shaft 21 is perpendicular to the axis of the mounting handle 12.
[0031] Compared with the prior art, in the first mounting bracket 1 of this embodiment, under the drive of the drive shaft 21, the mounting handle 12 rotates around its own axis, and then drives the tool disc 11 to rotate. The tool disc 11 can make the different tool heads installed on the tool disc 11 respectively align with the parts to be processed on the lathe during the rotation process, making the switching of the tool heads smoother and faster, solving the technical problem that the number of tool heads installed on the tool rest of the existing lathe is too small, and improving the machining efficiency of the lathe for the parts to be processed.
[0032] Furthermore, to facilitate the rotation of the cutter head 11, the second mounting bracket 2 further includes an operating wheel for driving the rotation of the drive shaft 21, so as to control the rotation angle of the cutter head 11 through the rotation of the operating wheel.
[0033] Based on the above embodiments, as a feasible implementation manner in the present utility model, a first bevel gear ring is sleeved on the outer periphery of the mounting handle 12, and the bevel gear ring is located in the mounting box 22. A second bevel gear ring is coaxially provided at one end of the drive shaft 21 located in the mounting box 22, and the first bevel gear ring meshes with the second bevel gear ring for transmission. With such a setting, in this embodiment, the transmission between the drive shaft 21 and the mounting handle 12 can be made more stable through the meshing transmission of the first bevel gear ring and the second bevel gear ring, and it is beneficial to maintain the transmission accuracy between the first mounting bracket 1 and the second mounting bracket 2. Furthermore, as a feasible implementation manner in the present utility model, the second mounting bracket 2 further includes a drive motor 23 and a machine base 24. The machine base 24 is provided at the bottom of the mounting box 22, and the drive motor 23 is provided on the machine base 24 and is used to drive the rotation of the drive shaft 21. With such a setting, in this embodiment, the drive shaft 21 can be driven to rotate by the drive motor 23, which improves the automation degree of the mounting structure of the tool rest in the present utility model and is beneficial to improving the processing efficiency of the parts in the present utility model.
[0034] As a feasible implementation manner in the present utility model, a plurality of mounting grooves for mounting turning tools are provided on the outer periphery of the cutter head 11, and the mounting grooves are evenly distributed around the axis of the cutter head 11. The setting of the mounting grooves provides more mounting positions for the turning tools, and solves the technical problem that the existing mounting positions of the tool rest cannot meet the requirements of the ring tool.
[0035] As a feasible implementation manner in the present utility model, the mounting structure of the turning tool further includes a first driving mechanism 3. The first driving mechanism 3 includes a first lead screw 31, a first guide rail 32 and a connecting plate 33 arranged side by side. Both the first lead screw 31 and the first guide rail 32 extend along the axial direction of the lathe spindle. The bottom of the machine base 24 is connected to the connecting plate 33. The bottom of the connecting plate 33 is threadedly adapted to the first lead screw 31 and is slidably adapted to the first guide rail 32. The first lead screw 31 can drive the machine base 24 to move along the first guide rail 32. With such a setting, in this embodiment, the rotation of the first lead screw 31 can drive the connecting plate 33 to move along the first guide rail 32, and then drive the cutter head 11 on the machine base 24 to move, so as to adjust the position of the cutter head 11 on the lathe.
[0036] Based on the above embodiments, under the same inventive concept, a feasible implementation manner is proposed. Specifically, the mounting structure of the turning tool further includes a second driving mechanism 4. The second driving mechanism 4 includes a second lead screw 41 and a second guide rail 42 both disposed on the connecting plate 33. The second lead screw 41 and the second guide rail 42 are both parallel to the horizontal direction and perpendicular to the axial direction of the lathe spindle. The bottom of the machine base 24 is threadedly engaged with the second lead screw 41 and slidably engaged with the second guide rail 42, and the second lead screw 41 can drive the machine base 24 to move along the second guide rail 42. In this way, this embodiment can drive the tool holder 11 to move in the horizontal direction through the mutual cooperation of the first lead screw 31 and the second lead screw 41, so as to facilitate adjusting the position of the tool holder 11 relative to the part. Further, in the above embodiment, preferably, the mounting structure of the turning tool further includes a first operating wheel 34 and a second operating wheel 43. The first operating wheel 34 is connected to the first lead screw 31 and is used to drive the first lead screw 31 to rotate. The second operating wheel 43 is connected to the second lead screw 41 and is used to drive the second lead screw 41 to rotate. In this embodiment, the first operating wheel 34 and the second operating wheel 43 facilitate the operator to control the rotation of the first lead screw 31 and the second lead screw 41, making the control process of the trajectory of the tool holder 11 in the present utility model more convenient.
[0037] In summary, compared with the prior art, the tool holder 11 in the present utility model can rotate around its own axis under the drive of the drive shaft 21, so that the tool heads at different positions on the tool holder 11 are respectively aligned with the parts to be machined on the lathe, making the switching of the tool heads smoother and faster, solving the technical problem that the existing lathe has too few tool heads installed on the tool rest, and improving the machining efficiency of the lathe for the parts to be machined; moreover, compared with the tool rest in the prior art, the integration degree of the turning tools on the tool holder 11 in the present utility model is higher, and since the rotation axis of the tool holder 11 is parallel to the spindle of the lathe, the tool holder 11 in the present utility model occupies less space on the lathe, which is beneficial to solving the technical problem that the tool head is prone to collide with the part or other components of the lathe during the tool change process. And when it is necessary to horizontally move the tool holder 11 to complete the tool change operation, since the tool holder 11 in the present utility model occupies less space in the axial direction, during the tool change process, it is only necessary to move the tool holder 11 along the horizontal direction away from the lathe spindle, without moving the tool holder 11 along the lathe spindle, reducing the number of components involved in the adjustment process of the tool holder 11 and being beneficial to maintaining the positioning accuracy of the tool holder 11.
[0038] Based on the same inventive concept, the present utility model also proposes a lathe, which includes the mounting structure of the turning tool described above.
[0039] Compared with the prior art, the lathe in the present utility model has all the beneficial effects of the above tool post mounting structure, and will not be elaborated here.
[0040] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
