This invention discloses a double-lobed toothed joint anti-vibration clamp, relating to the field of manufacturing fixtures for machining slender shaft fully threaded screws, to solve the vibration problem generated during the machining of existing slender shaft fully threaded screws. It includes an upper clamp and a lower clamp, which are symmetrically distributed. The contact point between the upper and lower clamps is set with a toothed joint. Both the upper and lower clamps are semi-annular structures. The upper and lower clamps are fixed to the slender shaft threaded screw to be machined via a detachable connection structure. The clamp formed by the upper and lower clamps can rotate with the rotation of the slender shaft threaded screw. During the rotational machining process, the slender shaft threaded screw is in a continuous transition state.

Description

Technical Field

[0001] A double-lobed toothed joint anti-vibration clamp is disclosed. This invention belongs to the field of machining technology for slender shaft fully threaded ball screws, specifically relating to the manufacturing technology of tooling fixtures for machining slender shaft fully threaded ball screws. Background Technology

[0002] The slender shaft fully threaded ball screw refers to a ball screw with a full thread length of nearly 5 meters and a length-to-diameter ratio of 33:1. This type of ball screw has poor workpiece rigidity, is made of high-temperature alloy that is difficult to cut, has a special multi-start thread, a thread length of 4 meters, and has extremely high requirements for thread profile, workpiece straightness, runout, and other precision. The workpiece is extremely difficult to process, and it is necessary to fix it during the processing of this type of ball screw.

[0003] For example, application number 201820247397.8 discloses a fixture for machining lead screws, including a fixture body. The fixture body has a lead screw fixing hole in the middle, and one end of the lead screw body passes through the inside of the lead screw fixing hole. A threaded through hole is vertically provided in the middle of the fixture body at the upper end of the lead screw fixing hole. Both ends of the lead screw are fixed by the fixture body to prevent it from swinging back and forth during machining and causing danger. The threaded part is screwed into the threaded through hole, and the inner end of the threaded part presses the lead screw to fix it, thereby enhancing the reliability of the fixation.

[0004] However, in the machining process of slender shaft fully threaded ball screws, if they cannot be properly fixed, the length and diameter of the workpiece being machined are insufficient to withstand the non-linear rotation generated during the rotation of a long workpiece, resulting in significant vibration. The aforementioned patent aims to address the issue of swaying, but it cannot solve the vibration caused by the swaying of long shafts. This vibration will still affect the cylindricity of the slender shaft fully threaded ball screw. Although the aforementioned patent can meet the machining requirements of ordinary ball screws, it cannot prevent vibration during the machining of slender shaft fully threaded ball screws. Therefore, we propose a double-lobed toothed joint anti-vibration clamp. Summary of the Invention

[0005] The purpose of this invention is to provide a double-lobed toothed joint anti-vibration slip to solve the vibration problem generated during the machining of existing slender shaft fully threaded screws.

[0006] The technical solution adopted in this invention is as follows:

[0007] A double-lobed toothed joint vibration damping clip includes an upper clip and a lower clip, which are symmetrically distributed. The contact position between the upper and lower clips is set with a toothed joint. Both the upper and lower clips are set with a semi-circular structure, and the upper and lower clips on both sides of the toothed joint are connected by a detachable connection structure.

[0008] In the technical solution of this application, the upper and lower bearings are fixed on the slender threaded screw to be processed by a detachable connection structure. Then, the bearings formed by the upper and lower bearings can rotate with the rotation of the slender threaded screw. During the rotation of the slender threaded screw, it is in a continuous transition process. When it rotates to the toothed joint position, due to the shape of the toothed joint between the upper and lower bearings, the long shaft processing will present a natural transition state, avoiding vibration and improving the cylindricity of the workpiece.

[0009] Furthermore, the detachable connection structure includes a first connecting block installed on the side of the upper tile on both sides of the toothed joint, and a second connecting block installed on both sides of the lower tile at the position corresponding to the first connecting block.

[0010] Furthermore, both connecting block one and connecting block two have through holes. Bolts are slidably installed inside the through holes, and nuts are threaded to the bottom ends of the bolts outside the through holes. By aligning the upper and lower tiles, the toothed joints of the upper and lower tiles are interlocked. Then, by passing the bolts through the through holes and tightening the nuts, the connection between the upper and lower tiles is completed, forming a locking mechanism. Furthermore, the detachable connection structure includes connecting block three installed on the sides of the upper tile on both sides of the toothed joint, and connecting block four installed on both sides of the lower tile at positions corresponding to connecting block three.

[0011] Furthermore, the connecting block three has a screw hole, and the connecting block four has a blind hole at the corresponding position of the screw hole. The screw hole and the blind hole are connected internally by a screw. By aligning the upper and lower tiles, the upper tile...

[0012] The toothed joints of the upper and lower tiles are interlocked, and then the screw is connected to the screw hole and blind hole, thereby tightening the connecting block three and connecting block four, thus completing the connection between the upper and lower tiles and forming a locking tile.

[0013] Furthermore, the inner walls of the upper and lower tiles are tangential to the outer wall of the slender, fully threaded lead screw to be processed, and both the inner and outer walls of the upper and lower tiles are smooth.

[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0015] 1. During the rotational machining of slender shaft threaded screws, the process is in a continuous transition state. When rotating to the toothed joint position, due to the shape of the toothed joint between the upper and lower bearings, the machining of the long shaft will present a natural transition state, avoiding vibration and improving the cylindricity of the machined workpiece.

[0016] 2. The slender threaded ball screw processed by this invention has a straightness of 0.008 / 300mm and a cylindricity of 0.005, which fully meets the design requirements. At the same time, the setting of the upper shell, lower shell and toothed joint can increase the diameter of the crankshaft clamping position, thereby expanding the processing range of the machine tool.

[0017] 3. The upper and lower tiles are symmetrically distributed, which simplifies their processing and reduces costs. Furthermore, the upper and lower tiles are connected by hinged bolts, making installation and fixing simple and convenient for operation.

[0018] 4. When the upper and lower tiles are connected by bolts and nuts, since the bolts and nuts are both outside the through hole, the user can more intuitively observe the connection between the upper and lower tiles and the slender threaded screw, ensuring the firmness of the connection between the slender upper and lower tiles and the long threaded screw.

[0019] 5. When the upper and lower tiles are connected using a structure of screw holes, blind holes, and screws, the upper and lower tiles can be connected and fixed to the long shaft threaded screw by tightening the screw. The operation is simple and facilitates quick connection and fixing. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of this invention clearer, the invention 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 merely illustrative and not intended to limit the invention.

[0026] Example 1

[0027] like Figures 1 to 4As shown, a double-lobed toothed joint vibration damping clip includes an upper tile 1 and a lower tile 2, which are symmetrically distributed. The contact position of the upper tile 1 and the lower tile 2 is set with a toothed joint 3. Both the upper tile 1 and the lower tile 2 are set with a semi-circular structure, and the upper tile 1 and the lower tile 2 on both sides of the toothed joint 3 are connected by a detachable connection structure.

[0028] In the technical solution of this application, the upper bearing 1 and the lower bearing 2 are fixed to the slender shaft threaded screw to be processed by a detachable connection structure. Then, the bearing formed by the upper bearing 1 and the lower bearing 2 can rotate with the rotation of the slender shaft threaded screw. During the rotation of the slender shaft threaded screw, it is in a continuous transition process. When it rotates to the toothed joint 3 position, due to the shape of the toothed joint 3 between the upper bearing 1 and the lower bearing 2, the long shaft processing will present a natural transition state, avoiding vibration and improving the cylindricity of the workpiece. The upper bearing 1 and the lower bearing 2 are symmetrically distributed, making the processing of the upper bearing 1 and the lower bearing 2 simpler, thereby reducing the processing cost. Furthermore, the upper bearing 1 and the lower bearing 2 are connected by a detachable connection structure, making the installation and fixing of the upper bearing 1 and the lower bearing 2 simpler, thus facilitating operation and use.

[0029] Example 2

[0030] like Figures 2 to 3 As shown, based on Embodiment 1, the detachable connection structure includes connecting block 1 4 installed on the sides of the upper tile 1 on both sides of the toothed joint 3, and connecting block 2 5 installed on both sides of the lower tile 2 at the positions corresponding to connecting block 1 4.

[0031] Both connecting block 4 and connecting block 5 have through holes 6. Bolts 7 are slidably installed inside the through holes 6. Nuts 8 are threaded to the bottom of the bolts 7 outside the through holes 6. By aligning the upper tile 1 and the lower tile 2, the toothed joints 3 of the upper tile 1 and the lower tile 2 are staggered. Then, by passing the bolts 7 through the through holes 6 and tightening the nuts 8, the connection between the upper tile 1 and the lower tile 2 is completed, thus forming a locking tile.

[0032] Example 3

[0033] like Figure 4 As shown, based on Embodiment 1, the detachable connection structure includes connecting block three 9 installed on the sides of the upper tile 1 on both sides of the toothed joint 3, and connecting block four 10 installed on both sides of the lower tile 2 at the positions corresponding to the connecting block three 9.

[0034] A screw hole 11 is provided on connecting block 3 9, and a blind hole 12 is provided on connecting block 4 10 at the position corresponding to the screw hole 11. The screw hole 11 and the blind hole 12 are connected by a screw 13. By aligning the upper tile 1 and the lower tile 2, the toothed joints 3 of the upper tile 1 and the lower tile 2 are connected in an alternating manner. Then, the screw 13 is connected to the screw hole 11 and the blind hole 12, thereby tightening connecting block 3 9 and connecting block 4 10, thus completing the connection of the upper tile 1 and the lower tile 2 and forming a locking piece. When the upper tile 1 and the lower tile 2 are connected using the structure of screw hole 11, blind hole 12 and screw 13, tightening the screw 13 can effectively connect and fix the upper tile 1 and the lower tile 3 to the long shaft threaded screw. The operation is simple and facilitates people to perform quick connection and fixing operations.

[0035] The inner walls of the upper tile 1 and the lower tile 2 are tangentially set to the outer wall of the slender, fully threaded lead screw to be processed, ensuring a large contact area between the upper tile 1 and the lower tile 2, thereby ensuring the fixing effect. The inner and outer walls of the upper tile 1 and the lower tile 2 are both smooth, which can prevent the hands from scratching other structures during use.

[0036] The toothed joint 3 after the upper tile 1 and lower tile 2 are joined can also be set to a diamond shape, arc shape, rectangle shape, etc. The multiple toothed designs allow users to choose according to their needs.

[0037] During operation: The upper bearing 1 and lower bearing 2 are connected by hinge bolts to form a clamp. The clamp joint is a toothed joint 3. During operation, the clamp is fixed to the outside of the shaft (i.e., the slender threaded screw) and rotates with the shaft. When the screw is being processed, the clamp is fixed in the middle of the thread being processed on the long shaft screw and supported by an external support structure. The end of the slender threaded screw is fixed to the rotating power structure. The rotating shaft contacts the horizontally moving tool, thereby completing the thread processing on the shaft. After the tool reaches the position of the clamp, processing stops. Then the clamp is moved to the position of the processed thread and installed. The clamp is then supported by an external support structure. Then the external rotating structure is started again, thereby driving the shaft to rotate again. At the same time, the tool continues to move horizontally, thus continuing the thread processing until the entire shaft is completely processed.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
