Abstract

This utility model discloses a double-conical composite positioning actuating tip, including a mounting handle. One end of the mounting handle is rotatably connected to an actuating end plate. A flange is provided at the end of the actuating end plate away from the mounting handle, and the flange is connected to the actuating end plate via a flange. Two symmetrical mounting holes are provided at the end of the flange near the actuating end plate. This double-conical composite positioning actuating tip, by setting two tips, allows the mounting handle to be pushed when one tip contacts a part with an uneven end face. This causes the tip in contact with the part to move its corresponding piston rod. The piston rod then moves the piston, causing hydraulic oil to flow in the connecting channel formed by the connecting holes, pushing out the other tip. Thus, both tips abut against the end face of the part. This device adaptively adjusts the positions of the two tips to accommodate parts with different end face concavity and convexity, making it widely applicable and convenient to use.

Description

Technical Field

[0001] This utility model relates to the field of cutting-edge technology, specifically a rotary tip with a double-cone composite positioning. Background Technology

[0002] A center is a machine tool component used in machining. There are two types: fixed centers and movable centers. Fixed centers can support parts with complex end faces and parts for which center holes cannot be drilled.

[0003] Existing actuating centers only support parts with relatively flat end faces using a single center. If the end face of the part is uneven or irregular, a single center cannot adequately support the part, easily leading to unstable clamping and failure to provide support. Therefore, we propose an actuating center with a double-cone composite positioning to solve the problems mentioned above. Utility Model Content

[0004] 1. The technical problem to be solved by the utility model:

[0005] The purpose of this invention is to provide a double-cone composite positioning actuating tip to solve the problems currently found in the market as described in the background.

[0006] 2. Technical Solution:

[0007] To achieve the above objectives, this utility model provides the following technical solution: a double-conical composite positioning actuating tip, comprising a mounting handle, one end of which is rotatably connected to an actuating end plate, and the end of the actuating end plate away from the mounting handle having a flange, the flange being connected to the actuating end plate via the flange, wherein...

[0008] The flange has two symmetrical mounting holes at one end near the actuating end plate. A piston rod is provided in each of the two mounting holes and the piston rod is slidably connected in the mounting hole. A first piston cylinder and a second piston cylinder are provided at one end of the actuating end plate corresponding to the two mounting holes. The first piston cylinder and the second piston cylinder correspond one-to-one with the two mounting holes. Hydraulic oil is provided in the first piston cylinder and the second piston cylinder.

[0009] The piston rod is connected to a piston at one end near the actuating end plate. The two pistons are located in the first piston cylinder and the second piston cylinder, respectively. Sealing rings are provided between the piston rod and the mounting hole, and between the piston and the first piston cylinder and the second piston cylinder. A tip is provided at the end of the piston rod away from the piston. The tip is engaged with the piston rod through a snap-fit ​​mechanism. A connecting hole is provided inside the actuating end plate, and the first piston cylinder and the second piston cylinder are connected through the connecting hole.

[0010] Preferably, the sealing ring has an annular cross-section, and the sealing ring is made of VITON fluororubber.

[0011] Preferably, the tip is connected to a rod near the piston rod, the piston rod has a rod groove at the end corresponding to the rod, the piston rod has a spring groove at the outer end near the rod groove, a spring is fixedly connected to the inner wall of the spring groove, a protrusion is fixedly connected to the other end of the spring, and a groove is provided at the end of the rod corresponding to the protrusion.

[0012] Preferably, the cross-sections of the insertion rod and the insertion rod groove are both rectangular, and a frosted layer is provided at the contact point between the insertion rod and the insertion rod groove.

[0013] Preferably, the spring is made of piano wire, and the surface of the spring is coated with an anti-rust coating.

[0014] Preferably, the end of the protrusion near the groove is a sphere, and the external dimensions of the protrusion are adapted to the internal dimensions of the groove.

[0015] 3. Beneficial effects:

[0016] Compared with the prior art, the specific details of the double-cone composite positioning actuating tip of this utility model are as follows:

[0017] This invention features two pointed tips. When one tip comes into contact with a part with an uneven end face, it pushes the mounting handle, causing the tip in contact with the part to move its corresponding piston rod. The piston rod then moves the piston, causing hydraulic oil to flow in the connecting channel formed by the connecting holes. This pushes out the other tip, so that both tips abut against the end face of the part. This device adaptively adjusts the positions of the two tips to accommodate parts with different degrees of unevenness in their end faces, making it widely applicable and convenient to use.

[0018] This invention, through a locking structure, allows the insertion rod at one end of the tip to be inserted into the insertion rod groove. When the insertion rod abuts against the protrusion in the insertion rod groove, the protrusion moves under force into the spring groove. When the protrusion aligns with the groove at the outer end of the insertion rod, the protrusion springs into the groove through the elastic connection formed with the spring, locking the insertion rod in the insertion rod groove, thereby installing the tip. At the same time, it also allows for easy disassembly and replacement of the tip, avoiding wear and tear from long-term use that could affect its performance. Attached Figure Description

[0028] Please see Figures 1 to 4 A double-cone composite positioning actuating tip includes a mounting handle 1, one end of which is rotatably connected to an actuating end plate 2. The end of the actuating end plate 2 away from the mounting handle 1 is provided with a flange 3, which is connected to the actuating end plate 2 via a flange.

[0029] Two symmetrical mounting holes 4 are provided at one end of the flange 3 near the actuating end plate 2. A piston rod 5 is provided in each of the two mounting holes 4. The piston rod 5 is slidably connected in the mounting hole 4. A first piston cylinder 6 and a second piston cylinder 7 are provided at one end of the actuating end plate 2 corresponding to the two mounting holes 4. The first piston cylinder 6 and the second piston cylinder 7 correspond one-to-one with the two mounting holes 4. Hydraulic oil is provided in the first piston cylinder 6 and the second piston cylinder 7.

[0030] A piston 8 is connected to one end of the piston rod 5 near the actuating end plate 2. The two pistons 8 are located in the first piston cylinder 6 and the second piston cylinder 7 respectively. A sealing ring 9 is provided between the piston rod 5 and the mounting hole 4, and between the piston 8 and the first piston cylinder 6 and the second piston cylinder 7. A tip 10 is provided at the end of the piston rod 5 away from the piston 8. The tip 10 is engaged with the piston rod 5 through a snap-fit ​​mechanism. A connecting hole 11 is provided inside the actuating end plate 2. The first piston cylinder 6 and the second piston cylinder 7 are connected through the connecting hole 11.

[0031] By setting two tips 10, when one tip 10 comes into contact with a part with an uneven end face, it can push the mounting handle 1, causing the tip 10 in contact with the part to move its corresponding piston rod 5. The piston rod 5 then moves the piston 8, causing hydraulic oil to flow in the connecting channel formed by the connecting hole 11, which pushes out the other tip 10. Thus, both tips 10 abut against the end face of the part. This device adapts to parts with different end face concavity and convexity by adaptively adjusting the positions of the two tips 10, making it widely applicable and convenient to use.

[0032] Please see Figures 2 to 3 The sealing ring 9 has a circular cross-section and is made of VITON fluororubber. By making the sealing ring 9 of VITON fluororubber, the sealing ring 9 has excellent weather resistance, ozone resistance and chemical resistance, and has better performance. The tip 10 is connected to the insertion rod 12 at the end near the piston rod 5. The piston rod 5 has an insertion rod groove 13 at the end corresponding to the insertion rod 12. The piston rod 5 has a spring groove 14 at the outer end near the insertion rod groove 13. A spring 15 is fixedly connected to the inner wall of the spring groove 14. A protrusion 16 is fixedly connected to the other end of the spring 15. The insertion rod 12 has a groove 17 at the end corresponding to the protrusion 16.

[0033] Insert the insertion rod 12 at one end of the tip 10 into the insertion rod groove 13. When the insertion rod 12 abuts against the protrusion 16 in the insertion rod groove 13, the protrusion 16 is moved into the spring groove 14 by force. When the protrusion 16 is aligned with the groove 17 at the outer end of the insertion rod 12, the protrusion 16 springs into the groove 17 through the elastic connection formed with the spring 15, and the insertion rod 12 is engaged in the insertion rod groove 13, thereby installing the tip 10.

[0034] Please see Figures 2 to 3 Both the insertion rod 12 and the insertion rod groove 13 have rectangular cross-sections. A frosted layer is provided at the contact point between the insertion rod 12 and the insertion rod groove 13. By making the cross-sections of the insertion rod 12 and the insertion rod groove 13 rectangular, it is convenient to limit the installation direction of the tip 10 and prevent the tip 10 from rotating freely with the piston rod 5. The spring 15 is made of piano wire and its surface is coated with an anti-rust coating. By making the spring 15 of piano wire, the spring 15 can have a high strength limit and elastic limit. By coating the surface of the spring 15 with an anti-rust coating, the spring 15 can have good corrosion resistance. The end of the protrusion 16 near the groove 17 is a ball. The external dimensions of the protrusion 16 are adapted to the internal dimensions of the groove 17. By making the end of the protrusion 16 near the groove 17 a ball, when the insertion rod 12 abuts against the protrusion 16, the protrusion 16 can be automatically moved into the spring groove 14 under force, avoiding obstruction to the installation of the insertion rod 12.

[0035] Working principle: When using this double-cone composite positioning actuating center, such as Figures 1 to 4 As shown, when one of the tips 10 contacts a part with an uneven end face, the mounting handle 1 can be pushed, causing the tip 10 in contact with the part to move its corresponding piston rod 5. The piston rod 5 then moves the piston 8, causing hydraulic oil to flow in the connecting channel formed by the connecting hole 11, which pushes out the other tip 10. Thus, both tips 10 abut against the end face of the part. This device adapts to parts with different end face concavity and convexity by adaptively adjusting the positions of the two tips 10. It has wide applicability and is easy to use, thereby completing a series of tasks.

[0036] Meanwhile, by setting a locking structure, the tip 10 and the piston rod 5 can be installed together, and the tip 10 can also be easily disassembled and replaced, avoiding wear and tear of the tip 10 over long-term use and affecting its performance.

[0037] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0038] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
