Description

Technical Field

[0001] The utility model relates to the technical field of lathe processing, and specifically relates to a shock-proof mechanism for turning processing. Background Technique

[0002] Lathe processing is a part of machining, and mainly has two processing forms: one is to fix the turning tool and process the unformed workpiece during rotation; the other is to fix the workpiece and perform precision machining through the transverse and longitudinal movement of the turning tool (tool rest) during the high-speed rotation of the workpiece.

[0003] Processing by fixing the turning tool and rotating the workpiece is more suitable for turning long shafts. During turning, the turning tool is parallel to the long shaft, and the length of the turning tool is longer than that of the long shaft. When the long shaft rotates, the turning tool contacts the surface of the long shaft for turning the long shaft.

[0004] However, for the lathe processing device in the prior art, when fixing the long shaft, only one end of the turning tool is fixed, so that when turning the long shaft, the turning tool used is also longer, and the unfixed end of the turning tool is prone to vibration, affecting the turning accuracy of the long shaft. Content of the Utility Model

[0005] The purpose of the utility model is to provide a shock-proof mechanism for turning processing to solve the problems raised in the above background technique.

The turning tool is used for turning a long shaft. An activity notch is arranged at one end of the fixing frame away from the bracket, and a movable fixing ring is arranged above the activity notch.

[0008] The top of the fixing ring is fixedly connected with an adjusting threaded shaft. A support rod is threadedly connected to the adjusting threaded shaft. Threads are arranged on the outer surface of the support rod. A plurality of fixing nuts are evenly welded and fixed to the bottom of the turning tool. The outer surface of the support rod is threadedly connected with the fixing nuts to fix one end of the turning tool away from the bracket to prevent the turning tool from vibrating.

[0009] Preferably, the bottom of the fixing ring is fixedly connected with a fixing screw shaft. The bottom of the fixing screw shaft penetrates through the activity notch and is threadedly connected with a locking nut to lock the fixing ring to the top of the fixing frame.

[0010] Preferably, an anti-slip washer is sleeved on the outer surface of the fixing screw shaft. The anti-slip washer is arranged between the locking nut and the bottom of the fixing frame to provide anti-slip protection for the locking nut.

[0011] Preferably, two inclined auxiliary rods are fixedly connected to the bottom of the fixed screw shaft. The two auxiliary rods are symmetrically arranged, and auxiliary support wheels are rotatably connected to both of the two auxiliary rods.

[0012] Preferably, two U-shaped positioning brackets are arranged on one side of the fixing frame. The upper horizontal end of the positioning bracket abuts against the top of the fixing ring, and the lower horizontal end of the positioning bracket abuts against the bottom of the locking nut. A transverse connecting plate is fixedly connected between the two positioning brackets, and the two positioning brackets are respectively arranged on both sides of the adjusting threaded shaft.

[0013] Preferably, a clamping notch is formed in the transverse connecting plate, and a clamping protrusion is fixedly connected to one side of the fixing frame. The clamping protrusion is adapted to the clamping notch.

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the scope of protection of the present invention.

[0025] An anti-vibration mechanism for turning processing includes a turning tool 2 and a fixed frame 3 installed on the same bracket 1. The fixed frame 3 is arranged below the turning tool 2. The turning tool 2 is used for turning a long shaft. An activity notch 4 is provided at one end of the fixed frame 3 away from the bracket 1, and a movable fixed ring 5 is provided above the activity notch 4.

[0026] The top of the fixed ring 5 is fixedly connected with an adjusting threaded shaft 6. A support rod 7 is threadedly connected to the adjusting threaded shaft 6. The outer surface of the support rod 7 is provided with threads. A plurality of fixed nuts 8 are evenly welded and fixed to the bottom of the turning tool 2. The outer surface of the support rod 7 is threadedly connected to the fixed nuts 8 to fix one end of the turning tool 2 away from the bracket 1 to prevent the turning tool 2 from vibrating.

[0027] As Figure 1 、 Figure 2 And Figure 3 , the bracket 1 is a part of the body of the turning processing equipment in the prior art. When turning a long shaft, the turning processing equipment drives the long shaft to rotate on one side of the turning tool 2, and the surface of the long shaft is turned by the turning tool 2. One ends of the turning tool 2 and the fixed frame 3 are both fixed to the bracket 1 through a bolt structure.

[0028] As Figure 1 And Figure 4 , the bottom of the support rod 7 has a cavity with threads inside to realize the threaded connection between the support rod 7 and the adjusting threaded shaft 6.

[0029] The bottom of the fixed ring 5 is fixedly connected with a fixed screw shaft 9. The bottom of the fixed screw shaft 9 penetrates through the activity notch 4 and is threadedly connected with a locking nut 10 to lock the fixed ring 5 to the top of the fixed frame 3.

[0030] As Figure 1, Figure 4 and Figure 5 , the fixed screw shaft 9 can move along the direction of the movable notch 4. The locking nut 10 is threadedly connected to the fixed screw shaft 9, and the positioning of the fixed ring 5 can be achieved by using friction to prevent the fixed ring 5 from loosening.

[0031] An anti-slip washer 11 is sleeved on the outer surface of the fixed screw shaft 9. The anti-slip washer 11 is arranged between the locking nut 10 and the bottom of the fixed bracket 3 to provide anti-slip protection for the locking nut 10.

[0032] As Figure 4 and Figure 5 , by using the anti-slip washer 11, the loosening and slipping of the locking nut 10 can be avoided.

[0033] Two inclined auxiliary rods 12 are fixedly connected to the bottom of the fixed screw shaft 9. The two auxiliary rods 12 are symmetrically arranged, and auxiliary support wheels 13 are rotatably connected to both of the two auxiliary rods 12.

[0034] As Figure 4 and Figure 5 , the two auxiliary support wheels 13 can abut against other components of the turning processing equipment to provide auxiliary positioning and support, and at the same time do not affect the movement of the fixed screw shaft 9, the fixed ring 5 and the support rod 7.

[0035] Two U-shaped positioning brackets 14 are arranged on one side of the fixed bracket 3. The upper horizontal end of the positioning bracket 14 abuts against the top of the fixed ring 5, and the lower horizontal end of the positioning bracket 14 abuts against the bottom of the locking nut 10. A transverse connecting plate 15 is fixedly connected between the two positioning brackets 14, and the two positioning brackets 14 are respectively arranged on both sides of the adjusting threaded shaft 6.

[0036] As Figure 4 and Figure 5 , the locking nut 10 can be restricted by using the positioning bracket 14. Its upper horizontal end abuts against the fixed ring 5, so that the positioning bracket 14 will not move downwards. Its lower horizontal end abuts against the bottom of the locking nut 10 to prevent the locking nut 10 from loosening and moving downwards, so that the locking nut 10 can maintain the locking of the fixed ring 5 and prevent the fixed ring 5 from loosening.

[0037] A clamping notch 16 is formed on the transverse connecting plate 15, and a clamping protrusion 17 is fixedly connected to one side of the fixed bracket 3. The clamping protrusion 17 is adapted to the clamping notch 16.

[0038] As Figure 4 and Figure 5 , the clamping protrusion 17 is exactly clamped in the clamping notch 16, and the clamping of the transverse connecting plate 15 and the positioning bracket 14 is achieved by using friction. On the contrary, by pulling the transverse connecting plate 15 away from the fixed bracket 3, the positioning bracket 14 can be removed.

[0039] The working principle of an anti-vibration mechanism for turning processing provided by the present utility model is as follows:

[0040] When it is necessary to adjust the position of the support rod 7 to fix and support different positions of the turning tool 2, first remove the positioning bracket 14. At this time, the support rod 7 can be rotated counterclockwise, causing the support rod 7 to move downward, and its top to separate from the fixing nut 8. Then, rotate the locking nut 10 counterclockwise to loosen the fixing ring 5. At this time, the fixing ring 5 can be moved horizontally to drive the adjusting threaded shaft 6 and the support rod 7 to move. Then, rotate the support rod 7 clockwise so that the top of the support rod 7 is threadedly connected to the fixing nuts 8 at different positions to fix one end of the turning tool 2. Then, rotate the locking nut 10 clockwise to lock the fixing ring 5, so that the adjusting threaded shaft 6 and the support rod 7 will not move.

[0041] Compared with the related art, an anti-vibration mechanism for turning processing provided by the present utility model has the following beneficial effects:

[0042] The present utility model sets a fixing device 3 at the bottom of the turning tool 2, and uses the support rod 7 to fix the end of the turning tool 2 away from the bracket 1, preventing the end of the turning tool 2 away from the bracket 1 from vibrating during the process of turning a long shaft, improving the turning precision of the long shaft. At the same time, the position of the support rod 7 can be adjusted, and the position of the fixing point of the support rod 7 and the turning tool 2 can be adjusted according to the different lengths of the long shaft to be turned as required.

[0043] The above shows and describes the basic principle, main features and advantages of the present utility model. Those skilled in the art of this industry should understand that the present utility model is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principle of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed.
