Description

Technical Field

[0001] This invention relates to the field of mechanical pump end cover processing tooling technology, specifically to a smart fan mechanical pump end cover tooling. Background Technology

[0002] In the manufacturing of mechanical pumps for fans, the machining precision of the end caps is crucial to the overall performance of the pump body. (Refer to...) Figure 1-3 It can be seen that the existing fan mechanical pump end cover is T-shaped and consists of end cover flange 1 and end cover cylinder 2, and the outer wall of end cover cylinder 2 is provided with axial protrusion 3;

[0003] To achieve efficient machining of the mechanical pump end cover for the fan, the standard tooling consists of a mounting frame, a top-pressure section, and a lateral limiting section. The mounting frame includes a base 4 and a mounting plate 5. Two sets of support frames 6 are symmetrically fixed between the mounting plate 5 and the base 4. A mounting ring platform 7 for supporting the mechanical pump end cover is fixedly mounted in the middle of the mounting plate 5. The top-pressure section consists of multiple sets of circumferentially distributed around the mounting ring platform 7, comprising a top-pressure arm 8, a rotating shaft 9, a top-pressure screw 10, and a nut 11. One end of the top-pressure arm 8 is rotatably connected to the top surface of the mounting plate 5 via the rotating shaft 9, and the other end abuts against the top surface of the end cover flange 1. The top-pressure screw 10 passes through the middle of the top-pressure arm 8 and is threadedly connected to the nut 11 at its bottom end. The lateral limiting section consists of two sets symmetrically distributed on both sides of the axial protrusion 3, comprising a mounting base 12 and abutment screws 13 threaded through its top end. The circumferential limiting of the end cover is achieved by the abutment screws 13 abutting against the axial protrusion 3.

[0004] However, based on the analysis of actual processing needs, the top pressure arm 8 of the existing tooling will partially obstruct the top surface of the end cover flange 1. Therefore, when performing processing operations such as grinding and precision inspection on the surface of the end cover flange 1, the top pressure part needs to be manually disassembled and the top pressure arm 8 needs to be deflected and stacked away from the top surface of the end cover flange 1 before the grinding operation can be conveniently carried out. As a result, the pump end cover loses the pressing effect of the top pressure part during the processing operation, which is very easy to cause unstable positioning. This increases the complexity of the process and significantly reduces the processing efficiency. Summary of the Invention

[0005] To solve the above-mentioned technical problems, an intelligent fan mechanical pump end cover tooling is provided, which solves the problems existing in the background technology.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a smart fan mechanical pump end cover tooling, the tooling including a mounting plate, a mounting ring platform fixedly passing through the middle of the mounting plate, and a plurality of top pressure parts distributed around the outer periphery of the mounting ring platform;

[0007] The top pressing part includes a top pressing arm, and a rotating shaft is fixedly inserted through the inner wall of one end of the top pressing arm. The bottom end of the rotating shaft is rotatably connected to the top surface of the mounting plate through a bearing. The tooling also includes a self-reversing base located below the mounting plate.

[0008] The self-reversing base includes a base, a movable hole passing through the middle of the base, and a deflection part disposed in the movable hole;

[0009] The deflection section includes a movable plate and an automatic force assembly that actively deflects the movable plate, the movable plate rotating within the movable hole.

[0010] Preferably, the automatic force assembly includes a ratchet fixed to the center of the bottom surface of the movable plate, a swing arm that can be deflected below the ratchet, and a movable frame disposed between the swing arm and the ratchet. One end of the swing arm is arranged corresponding to the center of the ratchet, and one end of the movable frame is elastically rotatably connected to the swing arm through a movable joint. The other end of the movable frame is fixed with a pawl, which is adapted to engage between two adjacent teeth of the ratchet.

[0011] Preferably, the movable section includes a movable rod that rotates within the inner wall of the swing arm. One end of the movable rod is fixed to the movable frame, and a torsion spring is fitted onto the rod body. The two ends of the torsion spring are respectively fixed to the surface of the movable rod body and the surface of the swing arm.

[0012] Preferably, the automatic force assembly further includes a drive rod and a deflection frame. The drive rod is erected between the mounting plate and the base. The bottom end of the drive rod rotatably passes through the base and is fixedly sleeved with one end of the deflection frame. The other end of the deflection frame is fixed with a deflection column. The other end of the swing arm is provided with a movable groove, and the deflection column slides in the movable groove.

[0013] Preferably, the top end of the drive rod rotates through the mounting plate and is fixedly connected to the bottom end of one of the rotating shafts.

[0014] Compared with the prior art, the advantages of the present invention are as follows: By setting a self-reversing base, after most of the processing operations on the surface of the end cover flange are completed, the top pressure screw is first turned along the loosening direction, and the tightening force is gradually released by the threaded engagement between the screw and the nut until the pressing and fixing of the top pressure arm on the top surface of the end cover flange is completely released; then the top pressure arm is deflected outward around the rotation axis, so that it is disengaged from the surface of the end cover flange to avoid the processing area. During this process, the movable plate in the self-reversing base is simultaneously deflected in a direction, which drives the lateral limiting part on its top surface and the mechanical pump end cover body to rotate with the movable plate, moving the area on the surface of the end cover flange that has not been polished due to the top pressure arm to the side; after the unprocessed area is in place, the top pressure arm is deflected again towards the end cover flange so that it abuts against the top surface of the end cover flange again, and the top pressure screw is turned to restore the tightening and fixing. At this time, the position of the top pressure arm avoids the unprocessed area that has been rotated to the side, and will not obstruct the subsequent polishing. Attached Figure Description

[0024] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0025] Reference Figure 1-7 As shown, a smart fan mechanical pump end cover fixture includes a mounting plate 5 and a self-reversing base located below the mounting plate 5. A mounting ring platform 7 is fixedly passed through the middle of the mounting plate 5. The mounting ring platform 7 supports a T-shaped mechanical pump end cover body. Several top pressure parts are distributed around the outer periphery of the mounting ring platform 7.

[0026] The self-reversing base includes a base 4, a movable hole through the middle of the base 4 and a deflection part provided in the movable hole. Two support frames 6 are symmetrically fixed between the mounting plates 5 of the base 4.

[0027] The deflection part includes a movable plate 14, which rotates within a movable hole;

[0028] The mechanical pump end cover body is composed of end cover flange part 1 and end cover cylinder part 2. The outer wall of end cover cylinder part 2 is provided with an axial protrusion 3. The end cover cylinder part 2 and the axial protrusion 3 are integrated through the inner side of the mounting ring platform 7, and the top surface of the mounting ring platform 7 abuts against the end cover flange part 1. The automatic part is provided with a lateral limiting part, which consists of two sets and is symmetrically distributed on both sides of the axial protrusion 3.

[0029] The top pressing part includes a top pressing arm 8 and a top pressing screw 10 passing through the middle of the top pressing arm 8. A rotating shaft 9 is fixedly passed through the inner wall of one end of the top pressing arm 8. The bottom end of the rotating shaft 9 is rotatably connected to the top surface of the mounting plate 5 through a bearing, and its other end abuts against the top surface of the end cover flange 1. The bottom end of the top pressing screw 10 is threadedly connected to a nut 11 that is fixed to the top surface of the mounting plate 5.

[0030] The lateral limiting part includes a mounting base 12 mounted on the top surface of the movable plate 14 and an abutting screw 13 threaded through the top of the mounting base 12, one end of the abutting screw 13 abutting against the side wall of the axial protrusion 3.

[0031] By setting up the top pressure part and the lateral limiting part, the mechanical pump end cover body to be processed is placed in advance. The end cover cylinder 2 and the axial protrusion 3 are inserted through the inner side of the bearing ring 7, so that the top surface of the bearing ring 7 abuts against the end cover flange 1, completing the initial bearing of the mechanical pump end cover body. Then, the top pressure arm 8 of the top pressure part is deflected so that one end abuts against the top surface of the end cover flange 1. Then, the top pressure screw 10 is screwed on, and the top pressure arm 8 is pressed against the top surface of the end cover flange 1 by using its threaded engagement with the nut 11, thereby achieving axial fixation of the mechanical pump end cover body. Finally, the abutment screw 13 of the lateral limiting part is turned so that one end of the abutment screw 13 abuts tightly against the side wall of the axial protrusion 3. The two sets of symmetrically distributed abutment screws 13 work together to restrict the circumferential movement of the mechanical pump end cover body, thereby completing the all-round clamping and positioning of the mechanical pump end cover body.

[0032] By setting a self-reversing base, after most of the machining operations on the surface of the end cover flange 1 are completed, the top pressure screw 10 is first screwed in the loosening direction, and the tightening force is gradually released by the threaded engagement between it and the nut 11 until the pressing and fixing of the top pressure arm 8 on the top surface of the end cover flange 1 is completely released. Then, the top pressure arm 8 is deflected outward around the rotating shaft 9, so that it is disengaged from the surface of the end cover flange 1 to avoid the machining area. During this process, the movable plate 14 in the self-reversing base is simultaneously deflected in a direction, which drives the lateral limiting part on its top surface and the mechanical pump end cover body to rotate with the movable plate 14, moving the area on the surface of the end cover flange 1 that has not been polished due to being covered by the top pressure arm 8 to the side. After the unmachined area is in place, the top pressure arm 8 is deflected again towards the end cover flange 1, so that it abuts against the top surface of the end cover flange 1 again, and the top pressure screw 10 is screwed in to restore the tightening and fixing. At this time, the position of the top pressure arm 8 avoids the unmachined area that has been rotated to the side, and will not obstruct the subsequent polishing.

[0033] Furthermore, referring to Figure 4-7 As shown, it is worth noting that the deflection part also includes an automatic force component that actively deflects the movable plate 14 in conjunction with the top pressure part.

[0034] The automatic force assembly includes a ratchet 15 fixed to the center of the bottom surface of the movable plate 14, a swing arm 18 that can be deflected below the ratchet 15, and a movable frame 19 disposed between the swing arm 18 and the ratchet 15. One end of the swing arm 18 is arranged corresponding to the center of the ratchet 15. One end of the movable frame 19 is elastically rotatably connected to the swing arm 18 through a movable joint. The other end of the movable frame 19 is fixed with a pawl 20, which is adapted to be engaged between two adjacent teeth of the ratchet 15.

[0035] The movable section includes a movable rod 25 that rotates within the inner wall of the swing arm 18. One end of the movable rod 25 is fixed to the movable frame 19. A torsion spring 26 is sleeved on the rod body of the movable rod 25. The two ends of the torsion spring 26 are fixed to the rod body of the movable rod 25 and the surface of the swing arm 18, respectively.

[0036] By setting up an automatic force component, when the top pressure arm 8 of the top pressure section deflects to release or restore the top pressure on the mechanical pump end cover body, it can simultaneously drive the swing arm 18 to deflect around one end of the corresponding bearing plate 5 center. During the processing, after completing the processing of most of the surface area of ​​the end cover flange 1, when the top pressure arm 8 is deflected to release the top pressure, the pawl 20 engages with the teeth of the ratchet 15, thereby pushing the ratchet 15 to drive the movable plate 14 to actively deflect, so that the lateral limiting part and the mechanical pump end cover body rotate synchronously, switching the area on the surface of the end cover flange 1 that was not processed due to the top pressure arm 8 to the side. Conversely, when the top pressure arm 8 deflects in the opposite direction to restore the top pressure, the torsion spring 26 drives the pawl 20 to elastically slide over the teeth of the ratchet 15, and the movable plate 14 maintains the current deflection position without retraction. In this way, the processing switching of the entire surface area of ​​the end cover flange 1 can be completed automatically without manual intervention, which significantly improves the efficiency of automated processing while ensuring the processing stability of the mechanical pump end cover body.

[0037] Furthermore, referring to Figure 4-7 As shown, it is worth noting that a U-shaped mounting frame 16 is fixed on the bottom surface of the base 4, and a movable shaft 17 is rotatably connected to the inner wall of the bottom end of the mounting frame 16. The movable shaft 17 is tightly sleeved with one end of the swing arm 18.

[0038] The automatic force assembly also includes a drive rod 21 and a eccentric frame 22. The drive rod 21 is erected between the mounting plate 5 and the base 4. The bottom end of the drive rod 21 rotates through the base 4 and is fixedly sleeved with one end of the eccentric frame 22. The other end of the eccentric frame 22 is fixed with an eccentric column 23. The other end of the swing arm 18 is provided with a movable groove 24, and the eccentric column 23 slides in the movable groove 24.

[0039] The top end of the drive rod 21 rotates through the mounting plate 5 and is fixedly connected to the bottom end of one of the rotating shafts 9;

[0040] By setting the automatic force component, when the top pressure arm 8 deflects around the rotating shaft 9, the rotating shaft 9 will synchronously drive the fixed drive rod 21 to rotate, thereby driving the deflection frame 22 sleeved at the bottom of the drive rod 21 to deflect. The deflection column 23 on the deflection frame 22 slides in the movable groove 24 of the swing arm 18, pushing the swing arm 18 to deflect around the movable shaft 17 as the fulcrum.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
