Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example

[0026] Depend on Figure 1-4 Provided is a positioning structure for machining wear-resistant sliding bearings, comprising a base 1;

[0027] A rotating motor 2 is mounted on the side of the base 1, and an output end of the rotating motor 2 is rotatably connected to a positioning seat 3;

[0028] A three-jaw chuck 4 is mounted on the side of the positioning seat 3, and a positioning structure 5 is detachably provided on the three-jaw chuck 4;

[0029] The positioning structure 5 includes a mounting seat 51 arranged on the three-jaw chuck 4, on which a lower processing seat 54 is mounted, and on which an upper processing seat 58 is slidably mounted. Both the lower processing seat 54 and the upper processing seat 58 are U-shaped and have openings facing each other.

[0030] In this embodiment, when it is necessary to process the wear-resistant sliding bearing workpiece, the user can use the positioning structure 5 to complete the clamping and positioning of the bearing workpiece. By connecting and installing the rotating motor 2 and the positioning seat 3, the rotation control of the three-jaw chuck 4 and the positioning structure 5 can be achieved, so that the bearing workpiece can be rotated without disassembling the bearing workpiece. Compared with the single use of a three-jaw chuck to position the bearing workpiece in the cited document, the rotatable positioning structure 5 in the present application can enable the bearing workpiece to achieve all-round rotation during the processing, so that the bearing workpiece can be easily processed at multiple angles and positions, meeting the processing needs of bearing parts of different shapes and requirements, further improving the processing efficiency and processing range, and saving time and labor costs.

[0031] Specifically, refer to Figure 1-4 A chuck shaft 41 is protruding from the three-jaw chuck 4, and an axial hole 53 is integrally formed at the center axis of the mounting seat 51. An internal thread is engraved inside the axial hole 53, and the chuck shaft 41 is threadedly connected to the axial hole 53.

[0032] In this embodiment, in actual use, through the threaded connection between the set shaft hole 53 and the chuck shaft 41, the set positioning structure 5 as a whole can be detachably installed on the three-jaw chuck 4. When the user needs to rotate the bearing workpiece, he only needs to align the shaft hole 53 with the chuck shaft 41 and tighten the thread to achieve the installation between the three-jaw chuck 4 and the positioning structure 5. Then, the power supply is connected to the rotating motor 2. Through the connection and installation between the rotating motor 2 and the positioning seat 3, and the installation between the three-jaw chuck 4 and the positioning structure 5, the rotation control of the three-jaw chuck 4 and the positioning structure 5 can be achieved, so that the bearing workpiece can be rotated without disassembling the bearing workpiece.

[0033] Specifically, refer to Figure 4 Two positioning holes 52 are formed through the side of the mounting seat 51 , and positioning pins are adapted to be arranged in the positioning holes 52 . The lower processing seat 54 is detachably assembled in the mounting seat 51 through the pin holes.

[0034] In this embodiment, the lower processing seat 54 can be detachably installed in the mounting seat 51, thereby realizing the disassembly, assembly and replacement of the lower processing seat 54. The user can use the corresponding positioning pin to insert the lower processing seat 54 into the mounting seat 51, and then match the positioning pin with the positioning hole 52 to realize the installation of the mounting seat 51 and the lower processing seat 54. The lower processing seat 54 can be used to clamp and surround a part of the bearing workpiece.

[0035] Specifically, refer to Figure 4 The lower processing seat 54 is provided with a slide groove 55 , and the upper processing seat 58 slides in the slide groove 55 . The upper processing seat 58 is provided with a plurality of heat dissipation grooves 510 .

[0036] In this embodiment, the slide groove 55 provided can be used for sliding adjustment of the upper processing seat 58. When the upper processing seat 58 goes deep into the slide groove 55, the distance between the upper processing seat 58 and the lower processing seat 54 is reduced, so that the small-sized wear-resistant sliding bearing parts can be clamped. When the upper processing seat 58 gradually separates from the slide groove 55, the large-sized wear-resistant sliding bearing workpiece can be clamped. The heat dissipation groove 510 provided can provide natural wind for circulation, thereby improving the heat dissipation efficiency between the upper processing seat 58 and the lower processing seat 54 and reducing high-temperature error operations during processing.

[0037] Specifically, refer to Figure 4 The lower processing seat 54 is provided with two pin holes 56, and the two pin holes 56 are both threadedly connected with positioning screws 57;

[0038] The upper processing seat 58 is symmetrically provided with two slots 59 along the central axis. The ends of the two positioning screw pins 57 respectively pass through a pin hole 56 and abut against the side walls of the adjacent slots 59 .

[0039] In this embodiment, in the actual positioning operation, the user loosens and adjusts the positioning screw 57 in the pin hole 56 so that the positioning screw 57 gradually disengages from the tight contact with the slot 59. At this time, the upper processing seat 58 provided can slide in the slide groove 55. Similarly, when the wear-resistant sliding bearing workpiece can be completely placed between the two, the user tightens the positioning screw 57 again so that the end of the positioning screw 57 is against the slot 59, thereby realizing the positioning of the upper processing seat 58 in the lower processing seat 54, and then achieving the clamping and positioning of the wear-resistant sliding bearing workpiece through the clamping of the upper processing seat 58 and the lower processing seat 54.

[0040] Specifically, refer to Figure 4 A plurality of cushion blocks 511 are installed on the inner walls of the upper processing seat 58 and the lower processing seat 54 .

[0041] In this embodiment, the set pad 511 can be used to surround and protect the outer wall of the wear-resistant sliding bearing workpiece, reduce the scratch damage to the outer wall of the bearing by the upper processing seat 58 and the lower processing seat 54 during positioning and clamping, and thus improve the safety of positioning the bearing workpiece. Compared with the clamping method in the cited document, the set pad 511 can provide better processing protection for the bearing workpiece, and the set pad 511 can be made of rubber material.

[0042] The utility model is a positioning structure for machining wear-resistant sliding bearings:

[0043] Step 1: In the actual processing operation, the user places the bearing workpiece to be processed between the upper processing seat 58 and the lower processing seat 54, and then rotates and adjusts the positioning screw 57 in the pin hole 56 so that the positioning screw 57 gradually breaks away from the tight contact with the slot 59. At this time, the upper processing seat 58 can slide in the slide groove 55. The user adjusts the distance between the upper processing seat 58 and the lower processing seat 54 according to the diameter size of the wear-resistant sliding bearing workpiece until the wear-resistant sliding bearing workpiece can be completely placed between the two. At this time, The user can slide the upper processing seat 58 to move it closer to the side of the lower processing seat 54 until the pads 511 set on the upper processing seat 58 and the lower processing seat 54 completely surround the wear-resistant sliding bearing workpiece and complete the clamping and positioning of the bearing member. At this time, the user tightens the positioning screw 57 again so that the end of the positioning screw 57 abuts against the slot 59, so that the upper processing seat 58 can be positioned in the lower processing seat 54, and further the clamping of the upper processing seat 58 and the lower processing seat 54 can be completed to clamp and position the wear-resistant sliding bearing workpiece.

[0044] Step 2: When the wear-resistant sliding bearing workpiece needs to be processed, the user can use the positioning structure 5 to complete the clamping and positioning of the bearing workpiece, and then connect the power supply to the rotating motor 2. By connecting and installing the rotating motor 2 and the positioning seat 3, the rotation of the three-jaw chuck 4 and the positioning structure 5 can be controlled, thereby allowing the bearing workpiece to be rotated without disassembling the bearing workpiece, thereby increasing the processing surface range during processing.
