[0036] The present example implementation provides a turning processing device 100 of a float assembly 130, as shown in Figure 1 The turning processing device 100 comprises:

[0037] The main shaft taper handle clamping part 110 and the tailstock taper handle clamping part 120 are oppositely arranged;

[0038] The main shaft end bearing 1124 is arranged at the center position of the clamping end of the main shaft taper handle clamping part 110, and the lever 1125 is arranged on the clamping end of the main shaft taper handle clamping part 110;

[0039] The tailstock end bearing 1224 corresponding to the main shaft end bearing 1124 is arranged at the center position of the clamping end of the tailstock taper handle clamping part 120;

[0040] A float assembly 130 is clamped between the main spindle taper shank clamp 110 and the tailstock taper shank clamp 120. The main spindle end bearing 1124 is connected to the first small shaft 131 at one end of the float assembly 130, and the tailstock end bearing 1224 is connected to the second small shaft 132 at the other end of the float assembly 130.

[0041] This application provides a turning apparatus 100 for a float assembly 130, which has at least the following beneficial effects:

[0042] (1) In this application, the main spindle end bearing 1124 is connected to the first small shaft 131, and the tailstock end bearing 1224 is connected to the second small shaft 132, which supports the float assembly 130 and makes the machining reference and the assembly reference consistent. At this time, the lever 1125 passes through the wire hole of the float assembly 130, thereby driving the float assembly 130 to rotate, realizing the outer circle turning of the float assembly 130;

[0043] (2) This application provides a first mounting hole 1123 for fixing the spindle end bearing 1124 and a second mounting hole 1223 for fixing the tailstock end bearing 1224, and ensures that the coaxiality of the first mounting hole 1123 and the second mounting hole 1223 with the machine tool spindle is less than 0.005mm, and the clearance between the spindle clamping part 112 and the tailstock clamping part 122 and the machine tool spindle is less than 0.002mm, thereby ensuring the positioning accuracy of the spindle end bearing 1124 and the tailstock end bearing 1224.

[0044] Existing float assemblies 130 generally include components such as a frame, gyroscope motor, sleeve, and small shaft. These components are assembled and then sealed by welding. To ensure assembly and adjustment accuracy, the outer diameter of the float assembly 130 needs to be machined. However, there is no machining positioning reference on the float assembly 130. To solve this problem, a special machining device 100 needs to be designed to perform the machining of the float assembly 130 and ensure the accuracy requirements of the assembled float assembly 130. Therefore, this application proposes a machining device 100 for a float assembly 130. The machining device 100 for the float assembly 130 proposed in this example embodiment will be described in more detail below.

[0045] In one embodiment, such as Figure 2 As shown, the spindle taper shank clamp 110 is described in detail. Figure 2 As can be seen, the spindle taper shank clamp 110 includes two parts: the spindle taper shank part 111 and the spindle clamp part 112.

[0046] The spindle taper shank 111 is conical, and the fixed end 1112 of the spindle taper shank is connected to the machine tool. In this embodiment, the machine tool spindle is inserted into the fixed end 1112 of the spindle taper shank, that is, the connection between the machine tool spindle and the fixed end 1112 of the spindle taper shank is achieved by inserting and pulling.

[0047] The connecting end 1121 of the spindle clamping part is fixedly connected to the connecting end 1111 of the spindle taper shank part. A spindle end bearing 1124 is provided at the center of the clamping end 1122 of the spindle clamping part, and a lever 1125 is provided on the clamping end 1122 of the spindle clamping part. Figure 1 In the middle, the lever 1125 is located above the spindle end bearing 1124.

[0048] Furthermore, a first mounting hole 1123 is provided at the center of the clamping end 1122 of the spindle fixture, and the outer ring of the spindle end bearing 1124 is placed in the first mounting hole 1123. In this embodiment, it is preferable to fix the outer ring of the spindle end bearing 1124 in the first mounting hole 1123 by dispensing adhesive. When the float assembly 130 is externally machined, the inner ring of the spindle end bearing 1124 is connected to the first small shaft 131 of the float assembly 130, which provides support for the float assembly 130.

[0049] Furthermore, by Figure 2 It can also be seen that in this embodiment, the spindle clamping part 112 is conical so that the first mounting hole 1123 and the spindle end bearing 1124 are on the same axis, thereby making the machining reference and the assembly reference consistent.

[0050] Furthermore, the coaxiality between the first mounting hole 1123 and the machine tool spindle is less than 0.005 mm, and the clearance between the spindle fixture part 112 and the machine tool spindle is less than 0.002 mm. This design ensures the positioning accuracy of the spindle end bearing 1124.

[0051] Furthermore, in this embodiment, the spindle taper shank 111 is preferably a Morse taper No. 3. However, different taper sizes can be used depending on the actual requirements during turning.

[0052] In one embodiment, such as Figure 3 As shown, the tailstock cone shank clamp 120 is described in detail. (From...) Figure 3 As can be seen, the tailstock cone shank clamp 120 also includes two parts: the tailstock cone shank part 121 and the tailstock clamp part 122.

[0053] The tailstock taper 121 is conical, and the fixed end 1212 of the tailstock taper 121 is connected to the machine tool. In this embodiment, the machine tool spindle is inserted into the fixed end 1212 of the tailstock taper 121, that is, the connection between the machine tool spindle and the fixed end 1212 of the tailstock taper 121 is achieved by inserting and pulling.

[0054] The connecting end 1221 of the tailstock clamp part is fixedly connected with the connecting end 1211 of the tailstock taper shank part, and the center position of the clamping end 1222 of the tailstock clamp part is provided with a tailstock end bearing 1224 corresponding to the main shaft end bearing 1124.

[0055] Further, the second mounting hole 1223 is arranged at the center position of the clamping end 1222 of the tailstock clamp part, and the outer ring of the tailstock end bearing 1224 is arranged in the second mounting hole 1223. In this embodiment, the outer ring of the tailstock end bearing 1224 is fixedly arranged in the second mounting hole 1223 by means of point gluing. When the float assembly 130 is subjected to external turning, the inner ring of the tailstock end bearing 1224 is connected with the first small shaft 131 of the float assembly 130, thereby supporting the float assembly 130.

[0056] Further, the tailstock end bearing 1224 is arranged in the second mounting hole 1223. Figure 2 It can also be seen that, in this embodiment, the tailstock clamp part 122 is a conical body, so that the second mounting hole 1223 and the tailstock end bearing 1224 are on the same axis, thereby making the machining reference and the adjustment reference consistent.

[0057] Further, the coaxiality of the second mounting hole 1223 with the main shaft of the machine tool is less than 0.005 mm, and the fitting gap of the tailstock clamp part 122 with the main shaft of the machine tool is less than 0.005 mm.

[0058] Further, in this embodiment, the tailstock taper shank part 121 is preferably a Morse No. 2 taper. Here, different types of tapers can be used according to actual requirements during turning.

[0059] The turning machining device 100 for the float assembly 130 proposed in this application can realize external turning of the float assembly 130 while ensuring the coaxiality of the external circle of the float assembly 130, thereby meeting the requirements of gyro adjustment. The specific working principle is as follows:

[0060] When the float assembly 130 is subjected to turning machining by means of the turning machining device 100 proposed in this application, first, the first small shaft 131 at one end of the float assembly 130 is connected with the inner ring of the main shaft end bearing 1124, and the second small shaft 132 at the other end of the float assembly 130 is connected with the inner ring of the tailstock end bearing 1224, thereby supporting and fixing the float assembly 130. At this time, the lever 1125 passes through the threading hole of the float assembly 130, i.e. is inserted into the float assembly 130, thereby driving the float assembly 130 to be subjected to low-speed external turning, and at the same time, the coaxiality requirement of the external circle of the float assembly 130 is met.
