[0035] See also Figure 1 to Figure 7 The honing device for the tailstock of a lathe of the present invention comprises a base, a support platform, a turning device and a fixing structure for fixing the tailstock of the lathe. The honing device for the tailstock of the lathe of the present invention has a loading state and a honing state.

[0036] The base includes a base body 11 and a support rod 12 fixedly connected to the base body 11 and extending upward from the base body 11. In one embodiment, the support rod 12 is located on the left side of the base body 11, and two support rods 12 are provided in the front and rear directions.

[0037] The support platform includes a support platform body 21 and a support column 22 fixedly connected to the support platform body 21 and extending downward from the support platform body 21. The support platform body 21 is used to support the lathe tailstock 8. The support column 22 is rotatably connected to the right side of the base body 11 around the first turning point A.

[0038] The flipping device includes a first rod 31, a second rod 32 and a screw mechanism (not shown in the figure) for driving the first rod 31 to retract and extend relative to the second rod 32. The first rod 31 has a first rod first end 311 and a first rod second end (not shown in the figure) respectively arranged in the length extension direction thereof. The second rod 32 has a second rod first end (not shown in the figure) and a second rod second end 322 respectively arranged in the length extension direction thereof. The first rod first end 311 is rotatably connected to the support platform around a second turning point B, and the first rod second end is cooperatively plugged with the second rod first end. In one embodiment, the first rod 31 is inserted into the second rod 32, and the second rod 32 is rotatably connected to the base around a third turning point C. The third turning point C is located between the second rod first end and the second rod second end 322. The second turning point B is higher than the first turning point A, the third turning point C is higher than the first turning point A, and the second turning point B is higher than the third turning point C. In one embodiment, the flipping device further includes a motor 33, which is disposed at the second end 322 of the second rod. By disposing the motor 33 at the second end 322 of the second rod, the weight of the motor 33 can be used to save effort when the flipping device flips the support platform.

[0039] The fixing structure includes an X-direction fixing component, a Y-direction fixing component and a Z-direction fixing component.

[0040] The X-direction fixing assembly includes an X-direction positioning block 41 and an X-direction fastening block 42 respectively arranged in the X-direction of the support platform, and an X-direction fastener 43 is screwed on the X-direction fastening block 42. The X-direction fastener 43 is used to abut against the lathe tailstock 8, thereby making the X-direction positioning block 41 abut against the lathe tailstock 8. Figure 3 As shown, in one embodiment, the X-direction fastening block 42 is disposed on the left side of the support platform, and two are disposed front and rear in the Y direction. Figure 7 As shown, in one embodiment, the X-direction fastening block 42 is disposed on the left side of the support platform, and one is provided. Figure 3 As shown, in one embodiment, an X-direction positioning block 41 is arranged in the middle of the support platform, and a groove for clamping the X-direction positioning block 41 is provided on the lathe tailstock 8. By providing the X-direction positioning block 41, the position of the lathe tailstock 8 can be quickly located when the lathe tailstock 8 is hoisted, thereby ensuring the honing accuracy during honing. By providing the X-direction fastener 43, the lathe tailstock 8 of different sizes can be adapted, and the specific adjustment can be made by twisting the X-direction fastener 43. The setting of the entire X-direction fixing assembly also prevents the lathe tailstock 8 from shifting in the X-direction, thereby ensuring the honing accuracy. Figure 3 and Figure 7 In the embodiment, the X-direction fastening blocks 42 are all arranged on the left side of the support platform.

[0041] The Y-direction fixing assembly includes a Y-direction positioning block (not shown in the figure) and a Y-direction fastening block 52 which are separately arranged in the Y direction of the support platform. The Y-direction fastener 53 is screwed on the Y-direction fastening block 52. The Y-direction fastener 53 is used to abut against the lathe tailstock 8, thereby making the Y-direction positioning block abut against the lathe tailstock 8. By setting the Y-direction positioning block, the position of the lathe tailstock 8 can be quickly located when the lathe tailstock 8 is hoisted, ensuring the honing accuracy during honing. By setting the Y-direction fastener 53, the lathe tailstock 8 of different sizes can be adapted, and the specific adjustment is made by twisting the Y-direction fastener 53. The setting of the entire Y-direction fixing assembly also prevents the displacement of the lathe tailstock 8 in the Y direction, ensuring the honing accuracy.

[0042] The Z-direction fixing assembly includes a Z-direction fixing member 61 and a Z-direction fastener 62. When in the loading state, the Z-direction fixing member 61 is used to be pressed on the lathe tailstock 8, and the Z-direction fastener 62 is inserted between the Z-direction fixing member 61 and the support table. By setting the Z-direction fastener 63, it can adapt to lathe tailstocks 8 of different sizes, and the specific adjustment is made by twisting the Z-direction fastener 63. When the support table flips around the first turning point A, the Z-direction fixing member 61 is pressed on the lathe tailstock 8 to prevent it from falling.

[0043] like Figure 7 As shown, in one embodiment, a Z-direction fixing member 61 is provided with a clearance groove 611 arranged along the length extension direction thereof, and a Z-direction fastener 62 is screwed into the clearance groove 611. By setting the clearance groove 611 and adjusting the position of the Z-direction fastener 62 in the length extension direction of the clearance groove 611, the Z-direction fixing assembly can be adapted to lathe tailstocks 8 of different sizes.

[0044] like Figure 3-4 As shown, when the honing device for the lathe tailstock 8 is in the loading state, the support platform extends in the horizontal direction. At this time, it is suitable for hoisting the lathe tailstock 8 and fixing the lathe tailstock 8 on the support platform through the fixing structure. The first rod 31 and the second rod 32 are relatively retracted, and the support rod 12 is supported under the support platform. After the installation, the sleeve 81 of the lathe tailstock 8 extends in the horizontal direction, and the second turning point B is set between the support rod 12 and the first turning point A. Figure 5-6 As shown, when the honing device for the lathe tailstock 8 is in the honing state, the support table extends in the vertical direction, and the sleeve 81 of the lathe tailstock 8 extends in the vertical direction. At this time, it is suitable for the honing tool to hone the sleeve 81 of the lathe tailstock 8, and the first rod 31 and the second rod 32 are relatively extended, and the support table is separated from the support rod 12. When switching from the loading state to the honing state, the motor 33 controls the movement of the screw mechanism to drive the first rod 31 to extend relative to the second rod 32, and the first end 311 of the first rod drives the support table to rotate around the first turning point A, and the second end 322 of the second rod moves upward around the third turning point C. When the support table rotates 90 degrees around the first turning point A, it stops.

[0045] like Figure 1-2As shown, in one embodiment, the honing device of the present invention includes a honing device for a lathe tailstock 8, a device base 7 for carrying the honing device for the lathe tailstock 8, an inner guardrail 9 and an outer guardrail 10, and the honing device for the lathe tailstock 8 can move relative to the device base 7 in the X direction and the Y direction. Specifically, the movement of the honing device relative to the device base 7 in the X direction can be set by an electric slide rail, the inner guardrail 9 is arranged above the device base 7 to form a protection when the honing device is in a honing state, and the outer guardrail 10 is arranged above the device base 7 and the periphery of the device base 7 to form a protection when the honing device is in a loading state, such as Figure 1-2 As shown, in one embodiment, the honing device moves to the left side of the equipment base 7. At this time, the top of the honing device is relatively open to prevent the lathe tailstock 8 from rubbing against other parts of the honing device when hoisting. When in the honing state, the honing device is located in the inner guardrail 9 to prevent people from approaching the honing device and causing injuries. The honing device can also be set to move in the Y direction relative to the equipment base 7 through an electric slide rail to adapt to different lathe tailstocks 8, thereby improving the versatility of the honing device.
