Description

Technical Field

[0001] This utility model belongs to the field of polishing machine technology, specifically relating to a dual-head polishing machine that is easy to maintain. Background Technology

[0002] A polishing machine is a device that uses a drive mechanism to rotate polishing parts to grind and polish the surface of workpieces. A double-head polishing machine has two polishing parts. The specific principle is that the position of the polishing parts is controlled by an electric telescopic cylinder, so that the polishing parts grind and polish the workpieces in contact with it. The telescopic shaft and polishing disc of the electric telescopic cylinder are connected as a whole. During long-term use, the polishing disc may develop defects and require maintenance. If the polishing disc and telescopic shaft are connected as a whole, it is inconvenient to disassemble and maintain. If the polishing disc and telescopic shaft are reinforced by multiple bolts, the disassembly and assembly of multiple bolts is cumbersome. In order to facilitate the quick assembly of the polishing disc and telescopic shaft, an assembly structure needs to be designed.

[0003] When the polishing disc on an existing polishing machine needs maintenance, there is a problem that there is no assembly structure between the telescopic shaft and the polishing disc that facilitates quick assembly and disassembly. To address this, this application proposes a dual-head polishing machine that is easy to maintain. Utility Model Content

[0015] 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.

[0016] Please see Figures 1 to 6 This utility model provides a technical solution: a dual-head polishing machine that is easy to maintain, including a polishing machine support platform 11 and an upper frame 12 fixedly connected, an electric telescopic cylinder 13 and a telescopic shaft 14 fixedly connected, and a polishing disc 15 combined with the telescopic shaft 14. The polishing disc 15 polishes the workpiece according to existing technology, which will not be described in detail in this application. It also includes a sleeve 2 sleeved on the outer side of the bottom end of the telescopic shaft 14. The inner side wall of the sleeve 2 is fixed with a support block 21. The sleeve 2 moves along the axial direction of the telescopic shaft 14 to facilitate changing the angle of the sleeve 2. The support block 21 supports the limiting frustum 7 to prevent the boss 3 and the limiting frustum 7 from detaching from the polishing disc 15 from the telescopic shaft 14. It also includes a connecting assembly for combining the polishing disc 15 and the telescopic shaft 14, including an integrally cast boss 3 and a limiting frustum 7. The boss 3 and the limiting frustum 7 are sleeved on the outer side of the telescopic shaft 14. When combined with the sleeve 2, the limiting frustum 7 is inserted into the sleeve. Inside the sleeve 2, the support block 21 passes through the slot 71. When the sleeve 2 rotates, the support block 21 supports the limiting frustum 7. It also includes a limiting component for connecting the sleeve 2 and the boss 3, including a welded mounting plate 4 and a plug-in post 5. One plug-in post 5 passes through the boss 3 and the telescopic shaft 14, and another plug-in post 5 passes through the sleeve 2, the support block 21, the limiting frustum 7, and the telescopic shaft 14, thus limiting the sleeve 2 and the boss 3 outside the telescopic shaft 14. It also includes components for... The locking assembly that fixes the plug-in post 5 and the telescopic shaft 14 includes a connecting plate 61, a pin 62 perpendicular to the connecting plate 61 and a locking pin 63, and a nut 64 screwed onto the locking pin 63. In order to further lock and fix the plug-in post 5, the pin 62 and the locking pin 63 pass through the plug-in post 5, and the nut 64 is screwed onto the locking pin 63 to prevent the locking pin 63 and the plug-in post 5 from loosening. At this time, the abutment plate 8 abuts against the sleeve 2 to prevent the connecting plate 61 from loosening.

[0017] In order to combine the sleeve 2 and the boss 3, in this embodiment, the telescopic shaft 14 passes through the center of the sleeve 2, the limiting frustum 7 and the boss 3. The top of the sleeve 2 is conical, the cross section of the limiting frustum 7 is a "T" shaped structure, the limiting frustum 7 has a slot 71 for the support block 21 to pass through, and the surface of the limiting frustum 7 has a pin hole 72 for the insertion pin 5 to pass through. One insertion pin 5 passes through the boss 3 and the telescopic shaft 14, and another insertion pin 5 passes through the sleeve 2, the support block 21, the limiting frustum 7 and the telescopic shaft 14, so as to limit the sleeve 2 and the boss 3 on the outside of the telescopic shaft 14.

[0018] In this embodiment, the telescopic shaft 14, sleeve 2, support block 21, and boss 3 are provided with through holes of the same diameter as the pin hole 72, so that the insertion post 5 can pass through the telescopic shaft 14, sleeve 2, support block 21, and boss 3.

[0019] In this embodiment, both the mounting plate 4 and the support block 21 are arc-shaped. There are two insertion pins 5 on the mounting plate 4. The pin 62 and the locking pin 63 pass through the insertion pins 5 to further lock and fix the insertion pins 5. The nut 64 is screwed and locked with the locking pin 63 to prevent the locking pin 63 and the insertion pins 5 from loosening. One end of the connecting plate 61 is welded with an arc-shaped abutment plate 8. The inner surface of the abutment plate 8 matches the outer surface of the sleeve 2. The abutment plate 8 abuts against the sleeve 2 to prevent the connecting plate 61 from loosening.

[0020] Working principle and usage process of this utility model: When the polishing disc 15 is disassembled for maintenance, loosen the nut 64 and remove the pin 62 and locking pin 63 from the plug pin 5. Then remove the mounting plate 4 and the plug post 5 from the sleeve 2 and the boss 3; Rotate sleeve 2 to change the position of support block 21; Move the sleeve 2 upward along the axial direction of the telescopic shaft 14, and the support block 21 passes through the slot 71; The boss 3 and polishing disc 15 can be removed from the telescopic shaft 14; This facilitates quick disassembly of the telescopic shaft 14 and the polishing disc 15; When the telescopic shaft 14 and the polishing disc 15 are assembled, the boss 3 and the limiting round table 7 are fitted onto the telescopic shaft 14. Sleeve 2 moves down and rotates, and support block 21 supports the limiting frustum 7; One insert post 5 passes through the boss 3 and the telescopic shaft 14; another insert post 5 passes through the sleeve 2, the support block 21, the limiting frustum 7, and the telescopic shaft 14. Nut 64 is screwed into locking pin 63 to prevent locking pin 63 and plug pin 5 from loosening; In summary: The telescopic shaft 14 and the polishing disc 15 of the dual-head polishing machine of this application are provided with an assembly structure that facilitates quick assembly and disassembly. The boss 3 and the limiting round platform 7 are combined and sleeved on the telescopic shaft 14. Under the cooperative action of the plug post 5, the pin 62, the locking pin 63 and the nut 64, the polishing disc 15 is fixed.
