Description

Technical Field

[0001] The utility model relates to the technical field of machining equipment, in particular to an auxiliary device which can quickly realize the adjustment of radial support rotation of a part to be machined. Background Art

[0002] When the lathe is processing a slender shaft, the part will shift laterally due to the cutting force of the turning tool, resulting in insufficient roundness of the outer circle of the part. Auxiliary tools are needed to balance the force to ensure the processing quality of the part.

[0003] There are many types of follow-up rests on the market. The most commonly used ones are to determine the center of the part by three points for positioning and clamping, and then use the follow-up rest to eliminate lateral side shift. The follow-up rest, also known as follow-up rest in English, is an auxiliary device used to radially support the rotating part to be processed. During the processing, the follow-up rest will move along the axial direction of the part to be processed together with the tool.

[0004] However, the commonly used tool rests are not very convenient for clamping parts during production and processing, and often require multiple adjustments and positioning. At the same time, the installation of conventional tool rests requires a certain amount of space, and some lathes do not support the installation of tool rests. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.

[0023] See also Figure 1 , is an auxiliary device for radially supporting and rotating a part to be processed provided by an embodiment of the utility model, such as Figure 1 As shown, the device may include:

[0024] Mounting bracket 1;

[0025] An adjusting unit, the adjusting unit comprising a screw sleeve 2 and a screw rod 3 connected to the screw sleeve 2; the screw sleeve 2 is connected to the top of the mounting bracket 1;

[0026] The contact unit includes a bearing mounting frame 4 and two bearings 5 ​​rotatably connected to the bearing mounting frame 4. The two bearings 5 ​​are coaxially arranged in a V shape and the symmetric center lines of the two bearings 5 ​​pass through the center of the part to be processed; the bearing mounting frame 4 is fixedly connected to one end of the screw 3; in specific implementation, the embodiment of the present application can provide that the two bearings 5 ​​are respectively connected to the bearing mounting frame 4 through two coaxially arranged pins 7. Further, the bearing mounting frame 4 is connected to the screw 3 through a bearing pressure plate 8.

[0027] Among them, the mounting bracket 1 is used to be fixed on the machine tool so that the screw 3 is located on the side of the part to be processed and the axial direction of the screw 3 is parallel to the axial direction of the tool; the adjustment unit is used to adjust the position of the contact unit so that the surfaces of the two bearings 5 ​​are in tangential contact with the surface of the part to be processed, ensuring that the part to be processed maintains straightness during rotation.

[0028] Furthermore, in order to ensure that the position of the screw 3 can be limited after the position adjustment of the screw 3 is completed, the embodiment of the present application can also provide a tightening screw 6, which is arranged in the screw hole of the screw sleeve 2, and the tightening screw 6 is used to tighten the screw 3 and the screw sleeve 2 after the position adjustment of the screw 3 is completed.

[0029] In order to further facilitate the rotation adjustment of the screw rod 3, the embodiment of the present application may provide that a wrench interface is provided at one end of the screw rod 3 away from the contact unit.

[0030] The auxiliary device for radially supporting and rotating a part to be processed provided in the embodiment of the present application positions and limits the part by contacting the outer diameter of the part with two bearings 5. The symmetrical center lines of the two bearings 5 ​​pass through the center of the part through the tangent arc. When installing the tool rest, the center lines of the two bearings 5 ​​are adjusted to be in line with the tool to ensure the processing accuracy. The two bearings 5 ​​contact the part in a "V-shaped limiter" manner to limit the freedom of the part in two directions, ensuring that the part always remains straight during the processing.

[0031] At the same time, the distance between the contact unit and the part is adjusted through the screw rod 3 structure, and real-time positioning is achieved through the tightening screw 6. The screw rod 3 and the tool rest bracket are connected by bearings to ensure that the tool rest always remains horizontal during the part processing process.

[0032] In addition, some lathes currently on the market have limited space and cannot be installed with a conventional tool rest. The auxiliary device for radially supporting and rotating the workpiece to be processed provided in the embodiment of the present application has a lightweight structure, does not require the tool travel, and can be used on most lathes.

[0033] When the auxiliary device for radially supporting and rotating a part to be processed provided by the embodiment of the present application is used, it is first installed on the machine tool through the mounting bracket 1, and the center of the screw rod 3 is adjusted to be level with the tool. The bearing mounting bracket 4 is connected to the screw rod 3 through the bearing, and can freely rotate to adjust the position and direction of the bearing 5. Two bearings 5 ​​are respectively installed on two pins 7, and the bearings 5 ​​can rotate flexibly. Rotate the screw rod 3, adjust the distance between the contact unit and the tool and the part, make the bearing 5 tangentially contact the part, and tighten the top screw 6 to fix the screw rod 3.

[0034] In summary, the auxiliary device for radially supporting and rotating the parts to be processed provided in the present application makes the way of clamping parts more convenient, occupies less space, has a wide range of applications, and improves the clamping efficiency. Through the V-shaped positioning and limiting of the two bearings, the straightness of the parts is ensured, and the processing quality and production efficiency of the parts are effectively improved. It is worthy of large-scale promotion and use.
