Abstract
Description
Technical Field
[0001] This utility model relates to the field of tooling technology, specifically to a tooling for deburring thin-walled irregularly shaped parts. Background Technology
[0002] Thin-walled irregular-shaped parts are widely used in aerospace, precision instruments and other fields, and their deburring process is crucial to the precision and performance of the parts.
[0003] Based on the above, the inventors have discovered the following problems: the main structure of the thin-walled irregular part has a thin wall and multiple wings on the outside. After the outer diameter is machined by CNC lathe, the burrs at the ends of the wings cannot be removed on the equipment. Removing burrs from the thin-walled irregular part by hand is inconvenient and can easily cause thin-wall deformation and scratches on the appearance, and the production efficiency is low.
[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a deburring tool for thin-walled irregular parts, in order to achieve a more practical purpose. Utility Model Content

Several T-shaped slots are opened on the outside of the positioning wheel, and the bottom end of the thin-walled irregular-shaped part body is inserted into the T-shaped slots.
[0008] Furthermore, the T-shaped slots are circumferentially distributed at equal intervals along the axis of the positioning wheel.
[0009] The beneficial effect of adopting the above-mentioned further solution is that the T-slots are evenly distributed around the circumference, which can clamp multiple thin-walled irregular parts at the same time. With the rotation of the positioning wheel, batch deburring operations can be realized, improving processing efficiency, while ensuring that the clamping position accuracy of each part is consistent.
[0010] Furthermore, the positioning wheel is made of nylon.
[0011] The beneficial effect of adopting the above-mentioned further solution is that the nylon material of the positioning wheel has good wear resistance and elasticity, which can avoid hard damage to the surface of the thin-walled irregular part and meet the flexible clamping requirements of the part.
[0012] Furthermore, a fastening screw is movably inserted at the center of one side of the positioning wheel.
[0013] The beneficial effect of adopting the above-mentioned further solution is that the fastening screw can fix the positioning wheel axially on the bushing, prevent the positioning wheel from moving axially during the deburring process, ensure that the parts are firmly clamped, and facilitate the removal of the positioning wheel to replace T-slot modules of different specifications.
[0014] Furthermore, one end of the bushing is provided with a threaded groove, and one end of the fastening screw is threadedly connected to the threaded groove.
[0015] The beneficial effect of adopting the above-mentioned further solution is that the threaded connection between the threaded groove and the fastening screw provides a reliable axial locking force, which, combined with the radial support of the bearing, keeps the positioning wheel stable when rotating at high speed, avoiding loosening of parts or machining errors due to vibration.
[0016] Furthermore, mounting holes are provided at both ends of one side of the connecting plate.
[0017] The advantages of adopting the above-mentioned further solution are that the mounting holes facilitate the fixing of the connecting plate to the workbench with bolts, enabling the tooling to be installed and positioned quickly, adapting to the installation requirements of different processing equipment, and improving the versatility of the tooling.
[0018] Furthermore, the connecting plate, fixing plate, and bushing are all made of stainless steel.
[0019] The beneficial effects of adopting the above-mentioned further solutions are that the stainless steel connecting plates, fixing plates and bushings have high strength and corrosion resistance, ensuring that the tooling is not easily deformed or rusted during long-term use, maintaining positioning accuracy and structural stability, and extending the service life of the tooling.

With the rotation of the positioning wheel, batch deburring operation can be realized, improving processing efficiency, while ensuring that the clamping position accuracy of each part is consistent; the nylon material of the positioning wheel has good wear resistance and elasticity, which can avoid hard damage to the surface of the thin-walled irregular part body and meet the flexible clamping requirements of the parts; the threaded groove and the threaded connection of the fastening screw provide reliable axial locking force, which, combined with the radial support of the bearing, keeps the positioning wheel stable when rotating at high speed, avoiding loosening of parts or processing errors due to vibration.

[0029] Example
[0030] Please see Figures 1-4 This utility model provides a technical solution: a deburring fixture for thin-walled irregular parts, including a main body 1, a fixing mechanism 2, and a thin-walled irregular part body 3. The main body 1 includes a connecting plate 101, a fixing plate 103 is fixedly installed on one side of the connecting plate 101, and a bushing 104 is fixedly installed on the upper side of the fixing plate 103. A bearing 105 is sleeved on one end of the bushing 104. The fixing mechanism 2 includes a positioning wheel 201, which is sleeved on the outside of the bearing 105. Several T-shaped slots 202 are opened on the outside of the positioning wheel 201. The bottom end of the thin-walled irregular part body 3 is inserted into the T-shaped slots 202. The connecting plate 101 and the fixing plate 103 of the main body 1 provide structural support. The bushing 104 cooperates with the bearing 105 to allow the positioning wheel 201 to rotate flexibly. The T-shaped slots 202 of the fixing mechanism 2 are inserted into the thin-walled irregular part body 3 to realize the rapid positioning of the part and facilitate subsequent deburring operations.
[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] Please see Figures 1-4Several T-slots 202 are evenly spaced circumferentially distributed along the axis of the positioning wheel 201. The positioning wheel 201 is made of nylon. A fastening screw 203 is movably inserted at the center of one side of the positioning wheel 201. One end of the bushing 104 has a threaded groove 106, and one end of the fastening screw 203 is threadedly connected to the threaded groove 106. Mounting holes 102 are provided at both ends of one side of the connecting plate 101. The connecting plate 101, the fixing plate 103, and the bushing 104 are all made of stainless steel. The T-slots 202 are evenly spaced circumferentially, which can clamp multiple thin-walled irregular parts 3 at the same time. With the rotation of the positioning wheel 201, batch deburring operations can be achieved, improving processing efficiency, while ensuring that the clamping position accuracy of each part is consistent. The nylon material of the positioning wheel 201 has good wear resistance and elasticity, which can avoid hard damage to the surface of the thin-walled irregular parts 3, and adapt to the flexible clamping requirements of the parts. The fastening screw 203 The positioning wheel 201 can be fixed axially on the bushing 104 to prevent axial movement of the positioning wheel 201 during deburring, ensuring that the parts are firmly clamped. At the same time, it is easy to disassemble the positioning wheel 201 to replace the T-slot 202 module of different specifications. The threaded connection between the threaded groove 106 and the fastening screw 203 provides reliable axial locking force. Combined with the radial support of the bearing 105, the positioning wheel 201 remains stable when rotating at high speed, avoiding loosening of parts or processing errors due to vibration. The mounting hole 102 makes it easy to fix the connecting plate 101 to the worktable with bolts, realizing the quick installation and positioning of the tooling, adapting to the installation requirements of different processing equipment, and improving the versatility of the tooling. The stainless steel connecting plate 101, fixing plate 103 and bushing 104 have high strength and corrosion resistance, ensuring that the tooling is not easily deformed or rusted during long-term use, maintaining positioning accuracy and structural stability, and extending the service life of the tooling.
[0033] Specifically, the working principle of this thin-walled irregular-shaped parts deburring fixture is as follows: First, the connecting plate 101 is fixed to the worktable through the mounting hole 102 to ensure the stability of the main body 1. The bottom end of the thin-walled irregular-shaped part body 3 is inserted into the T-slot 202 of the positioning wheel 201. Multiple thin-walled irregular-shaped parts bodies 3 can be clamped simultaneously using the circumferentially evenly distributed T-slots 202. Then, the fastening screws 203 are tightened to thread them into the threaded groove 106 of the bushing 104, locking the positioning wheel 201 axially to the outside of the bearing 105. The bearing 105 provides radial support. The support ensures that the positioning wheel 201 rotates stably without any slippage. During the processing, the user rotates the positioning wheel 201, which rotates flexibly under the action of the bearing 105, driving the thin-walled irregular part body 3 to rotate. This allows the operator to remove the burrs at the wing ends of the thin-walled irregular part body 3 one by one with a file. Since the positioning wheel 201 is made of nylon, it drives the thin-walled irregular part body 3 to rotate through elastic contact and moderate friction, while avoiding damage to the thin-walled surface. After processing, the thin-walled irregular part body 3 can be removed from the T-slot 202.
