Description

Technical Field

[0001] This utility model belongs to the field of special equipment disassembly and assembly technology, and relates to a disassembly device for the internal threaded ring of a conical shell component. Background Technology

[0002] Conical housing components are widely used in manufacturing and also have applications in artificial intelligence and automation. These components often house threaded rings with varying functions. The connection between the conical housing and the threaded rings is typically a threaded connection, and the tightening torque of the threaded rings is generally quite high, reaching up to 350 N·m. When problems arise during part processing, assembly, and inspection, it is necessary to disassemble the threaded rings for inspection to determine the cause of the problem. Currently, threaded rings are disassembled manually. Due to the high tightening torque, manual disassembly is time-consuming, labor-intensive, and prone to damaging the conical housing. Therefore, a specialized device is needed to assist in the disassembly of the threaded rings. Utility Model Content

The fixing component includes a platform with a gripper assembly. A circular through-hole is located at the center of the platform, and several bolts A are evenly distributed around the through-hole, penetrating the platform. Each bolt A is sequentially connected to a nut A, a long threaded sleeve, a nut B, and a bolt B. All nuts B and bolts B are connected to the same base plate, which has a circular through-hole at its center. The diameter of the circular through-hole at the center of the platform is larger than the outer diameter of the conical shell component. Bolts A, nuts A, long threaded sleeves, nuts B, and bolts B are distributed around the circumference, and bolts A and B are connected by long threaded sleeves. The mounting hole on the base plate is an oblong hole, fixed by nuts B and bolts B, and the base plate has a circular through-hole at its center. The gripper assembly includes two bases symmetrically fixedly connected to the platform. Grippers are slidably connected to the bases. A screw rod is threadedly connected to the rear of the gripper, passing through the base and rotatably connected thereto. A handwheel is fixedly connected to the rear of the screw rod. The cylindrical tail of the gripper is installed in the through hole of the base, with a clearance fit between the two. The center of the cylindrical tail of the gripper has a long threaded hole. The base has a stepped circular through hole inside and a threaded hole on its outer edge. The base is fixed to the platform by screws. The screw rod is divided into a threaded part and an unthreaded part. The threaded part mates with the long threaded hole of the gripper. The disassembly assembly includes a bracket fixed to a platform, a long bolt threaded onto the bracket, a connecting rod slidably connected to the long bolt via a spring, two wrenches fixedly connected to the bottom of the connecting rod, and end plates fixedly connected to the wrenches via set screws.

[0005] The rear of the gripper is fixedly connected to a cover plate by screws, and the cover plate has a circular hole that matches the screw.

[0006] The base has a baffle that is slidably connected to the screw at the rear. The screw has an annular groove that is slidably connected to the baffle. The unthreaded part has an annular groove in the middle and a keyway on the outer edge of the end.

[0007] The baffle is divided into two semi-circular plates, upper and lower.

[0008] The gripper head is a V-shaped block.

[0009] The base is threaded with a locking screw, the bottom of which abuts against the jaws.

[0014] Example 1 like Figures 1-6 As shown, a device for disassembling the internal threaded ring of a conical housing component includes a fixing component 1 and a disassembly component 2, wherein the disassembly component 2 is installed directly above the fixing component 1; the conical housing component 3 is fixedly installed on the fixing component 1; the conical housing component 3 includes a housing 5, a threaded ring 4, and a threaded sleeve 6, and the threaded ring 4 is disassembled by the disassembly component 2.

[0015] like Figure 3 As shown, the fixing assembly 1 includes a gripper assembly 7, a platform 8, bolts A9, nuts A10, long threaded sleeves 11, nuts B12, bolts B13, a base plate 14, and a fixing plate A15. The platform 8 has a circular through hole in the center, the diameter of which is larger than the outer diameter of the conical shell 3. Bolts A9, nuts A10, long threaded sleeves 11, nuts B12, and bolts B13 are distributed at four points around the circumference, and bolts A9 and B13 are connected by long threaded sleeves 11. The mounting hole of the base plate 14 is an oblong hole, which is fixed by nuts B12 and bolts B13. The base plate 14 has a circular through hole in the center. The fixing plate A15 has a cylindrical boss in the middle, and the boss has a circular through hole in the center. The fixing plate A15 is installed in the circular hole in the center of the base plate 14 and is fixed by screws.

[0016] like Figure 4As shown, the gripper assembly 7 includes a gripper 16, a base 17, a screw 18, a cover plate 19, a baffle 20, a handwheel 21, and a locking screw 22. The head of the gripper 16 is a V-shaped block, and the tail cylindrical part is installed in the through hole of the base 17 with clearance fit. The center of the tail cylindrical part of the gripper 16 has a long threaded hole. The base 17 has a stepped circular through hole inside and a threaded hole on the outer circle. The base 17 is fixed to the platform 8 by screws. The screw 18 is divided into a threaded part and an unthreaded part. The threaded part is connected to the gripper 16 by a screw. The screw rod 18 has a threaded hole and an annular groove in the middle of the unthreaded part, and a keyway on the outer circle of the end. The cover plate 19 and the clamp 16 are fixed by screws. The cover plate 19 has a circular hole in the center, through which the screw rod 18 passes. The baffle 20 is divided into upper and lower semi-circular plates with a circular hole in the center. The baffle 20 is inserted into the annular groove of the unthreaded part of the screw rod 18 and fixed to the base 17 by screws. The handwheel 21 is fixed to the end of the screw rod 18 by a key. The locking screw 22 is installed in the threaded hole on the outer circle of the base 17.

[0017] like Figure 5 As shown, the disassembly assembly 2 includes a bracket 23, a long bolt 24, a spring 25, a connecting rod 26, a wrench 27, an end piece 28, and a set screw 29. The bracket 23 is U-shaped and is fixed to the platform 8 with screws, and has a threaded through hole in the middle. The long bolt 24 is installed in the threaded through hole of the bracket 23, and has a blind hole at the bottom. The spring 25 is installed in the blind hole of the long bolt. The cylindrical end of the connecting rod 26 is installed in the blind hole at the bottom of the long bolt 24 and contacts the spring 25. There are two wrenches 27, distributed on both sides of the non-cylindrical end of the connecting rod 26, and connected to the connecting rod 26 with screws. The wrench 27 has a disassembly hole for the end piece 28. The end piece 28 is installed at the bottom of the wrench 27 and locked by the set screw 29. A limiting plate and a limiting platform can also be set between the connecting rod 26 and the bolt 24 to prevent the connecting rod 26 from coming out of the long bolt 24, causing parts to be lost or damaged.

[0018] There are two sets of gripper assemblies 7, which are symmetrically distributed on both sides of the central circular hole of the platform 8. The central axis of the gripper assembly 7 is parallel to the long side of the oblong hole of the substrate 14, and perpendicular to the plane where the bracket 23 is located.

[0019] The gripper 16 and the base 17, the base 17 and the cover plate 19, the screw 18 and the cover plate 19, and the screw 18 and the baffle 20 are all clearance fits.

[0020] The connecting rod 26 has a circular through hole at the center of its non-cylindrical end.

[0021] The end piece 28 can be replaced according to the shape of the disassembly groove of the threaded ring 4.

[0022] The fixing plate A15 can be replaced by the fixing plate B30, which is used to fix the conical housing part 3 when the screw sleeve 6 is not installed. The fixing plate B30 has a cylindrical pin for positioning.

[0023] The specific implementation steps are as follows: (taking State 1: Screw sleeve already installed as an example) S1. Install the fixing plate A15 with the protrusion facing down in the center hole of the substrate 14 and fix it with screws. Loosen the nut B12 that fixes the substrate 14.

[0024] S2. Based on the outer diameter of the conical housing part 3 and the position of the axis of the long bolt 24, adjust the position of the jaws 16 in the two sets of jaw assemblies 7 so that the inscribed circle formed by the V-shaped blocks of the two jaws 16 is slightly larger than the outer diameter of the conical housing part 3, and the central axis of the inscribed circle roughly coincides with the axis of the long bolt 24. The adjustment method for jaws 16 (using...) Figure 4 For example): Turning handwheel 21 clockwise moves screw 18 to the right. When surface a of screw 18 contacts surface A of baffle 20, continue turning handwheel 21 clockwise and jaw 16 moves to the left until surface d of jaw 16 contacts surface D of base 17, at which point jaw 16 reaches its left limit position. Turning handwheel 21 counterclockwise moves screw 18 to the left. When surface b of screw 18 contacts surface B of baffle 20, continue turning handwheel 21 counterclockwise and jaw 16 moves to the right until surface e of cover plate 19 contacts surface E of base 17, at which point jaw 16 reaches its right limit position.

[0025] S3. Place the conical housing part 3 in the middle of the clamp 16, with the tip inserted into the round hole of the fixing plate A15. Adjust the position of the clamp 16 using the handwheel 21 to fix the conical housing part 3.

[0026] S4. Install the spring 25 and the connecting rod 26, which is equipped with the wrench 27, end piece 28, and set screw 29, into the blind hole at the bottom of the long bolt 24. Fine-tune the position of the clamp 16 and the base plate 14, and rotate the connecting rod 26 so that the end piece 28 is engaged in the disassembly groove of the threaded ring 4. Lock the clamp 16 with the locking screw 22 and lock the base plate 14 with the nut B12.

[0027] S5. Insert a long rod into the circular through hole at the center of the non-cylindrical end of the connecting rod 26, and manually rotate the long rod to disassemble the threaded ring 4.

[0028] If the screw sleeve is not installed, the fixing plate A15 can be replaced with the fixing plate B30 for fixing the conical housing part 3 when the screw sleeve 6 is not installed. The fixing plate B30 has a cylindrical pin for positioning. The conical housing part 3 in S3 is placed in the middle of the clamp 16. The end of the screw sleeve is positioned by the positioning cylindrical pin on the fixing plate B30. The other steps are the same as those with the screw sleeve installed.
