Description

Technical Field

[0001] The utility model belongs to the technical field of medal grinding, in particular to a fixing device for medal grinding. Background Art

[0002] Medal polishing is a key step in the medal manufacturing process, the purpose of which is to make the medal surface smooth and flat, and show the ideal gloss and beauty. During the polishing process, it is very important to ensure that the medal is fixed in place to avoid uneven polishing or accidental damage caused by sliding or moving.

[0003] At present, there are some polishing and fixing structures on the market. For example, a polishing and fixing device is disclosed on the China Patent Network, and its announcement number is CN210588760U. This polishing and fixing device has a simple structure, is stable after fixing, and has high processing accuracy. However, there are some defects and shortcomings that need to be improved: (1) Some existing polishing and fixing devices are fixed by tightening fasteners such as screws. However, since the medal is round, when it is necessary to polish the edge of the medal, a part of it cannot be polished due to the obstruction of the fasteners, and the surface of the medal is easily damaged when the medal is fixed by fasteners such as screws; (2) Some existing polishing and fixing devices are not suitable for the purpose of polishing. Some polishing and fixing devices have poor flexibility. After the medal is fixed, it is difficult to fine-tune the fixing angle. When it is necessary to polish different positions of the medal, the medal can only be taken off and the angle adjusted before being fixed again. This is rather cumbersome, which not only reduces work efficiency but also increases the workload of the staff; (3) Due to the structural design, some existing polishing and fixing devices are difficult to timely recover the debris generated during the polishing process, so that the debris will fall and scatter all over the surface of the fixing device, which is not convenient for subsequent unified cleaning. Moreover, when the debris falls and adheres to the surface of the fixing component, it will also affect its subsequent fixing effect. Therefore, in view of the above problems, the medal polishing and fixing device provided by the utility model is of great significance. Utility Model Content

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.

[0030] In the description of the present invention, it should be understood that terms such as "relative", "one end", "inside", "lateral", "end", "two ends", "both sides", "front", "one end face", "the other end face" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0031] See also Figure 1-6 As shown, a fixing device for medal polishing of the utility model comprises a base 1, a fixing shaft 2 is fixedly connected to the top of the base 1, a clamping block 3 is fixedly connected to the top of the fixing shaft 2, the cross section of the clamping block 3 is circular, and a fixing component is arranged on the clamping block 3, a fixing frame 4 is fixedly connected to the base 1, a through hole 5 is opened at the top center of the fixing frame 4, and threaded holes 6 are opened on both sides of the fixing frame 4, a screw 7 matching with the threaded hole 6 is connected to the inner thread of the threaded hole 6, and a recovery component is arranged on the fixing frame 4;

[0032] The fixed component includes a movable seat 8, the cross section of the movable seat 8 is circular, and an adjustment groove 9 is provided on its side wall, and a card slot 10 is provided on the bottom of the movable seat 8. The top and bottom diameters of the card slot 10 are respectively equal to the diameters of the block 3 and the fixed shaft 2, and the top height of the card slot 10 is equal to the thickness of the block 3. The movable seat 8 can be limited by the mutual cooperation between the card slot 10 and the block 3 so that it can rotate around the fixed shaft 2. A vacuum cylinder 11 is fixedly connected to the top of the movable seat 8. The vacuum cylinder 11 is cylindrical, and its top is a sealing structure. It passes through the through hole 5 and extends to the top of the fixed frame 4. A vacuum port 12 is provided on the wall of the vacuum cylinder 11. The vacuum port 12 is connected to the inner cavity of the vacuum cylinder 11, and a vacuum valve 13 is installed on the vacuum port 12. A plurality of vacuum tubes 14 are provided on the top wall of the vacuum cylinder 11. The air port 12 can be connected to an external exhaust fan. After the medal to be polished is placed on the top of the vacuum cylinder 11, the vacuum valve 13 is opened and the air in the vacuum cylinder 11 is extracted through the external exhaust fan. At this time, due to the reduction of the air pressure in the vacuum cylinder 11, suction will be generated through each vacuum tube 14, so that the medal is firmly adsorbed and fixed on the top of the vacuum cylinder 11 under the action of vacuum. Compared with the traditional fixing method of fasteners such as screws, it is convenient to polish the edge of the medal, and at the same time, it is also effectively avoided to cause damage to the surface of the medal. When the medal is fixed on the top of the vacuum cylinder 11, the movable seat 8 can be rotated to drive the vacuum cylinder 11 to rotate together with the medal to achieve fine adjustment of the fixed angle, so that different positions of the medal can be polished without removing the medal, which not only greatly improves the work efficiency, but also effectively reduces the workload of the staff.

[0033] The recovery component includes a pair of recovery trays 15, which are semicircular and have a positioning groove 16 on one side. A plurality of positioning rods 17 are fixedly connected to the bottom of the recovery tray 15. The pair of recovery trays 15 can be spliced ​​into a complete circular tray after being fitted together. When polishing the medals, the fallen debris can be recovered in time through the recovery trays 15, thereby avoiding the difficulty in uniform cleaning after the debris is scattered everywhere.

[0034] Among them, the adjustment groove 9 is an annular groove structure, and its groove width is equal to the aperture of the threaded hole 6, and the adjustment groove 9 is flush with the height of the threaded hole 6. By tightening the screw 7 in the threaded hole 6, the end of the screw 7 can be inserted into the adjustment groove 9 until the end of the screw 7 is tightly against the side wall of the movable seat 8. At this time, the movable seat 8 can be fixed by the mutual cooperation between the screw 7 and the adjustment groove 9 to prevent it from deflecting during the medal polishing process.

[0035] Among them, a pad 18 is arranged on the top surface of the vacuum cylinder 11, and the surface of the pad 18 is engraved with a herringbone anti-skid pattern. The pad 18 is made of cylindrical rubber material and is fixed by glue or the like. When the medal is placed on the top of the vacuum cylinder 11, the pad 18 can be placed on the bottom of the vacuum cylinder 11 to play a certain anti-wear protection role, thereby avoiding wear on the bottom of the medal. At the same time, the anti-skid pattern on the surface of the pad 18 can increase the friction between the medal and the vacuum cylinder 11 to play an anti-skid role, thereby effectively preventing the medal from slipping and displacement after being fixed.

[0036] The vacuum tubes 14 are L-shaped and are equidistantly distributed in an annular pattern along the circumference of the vacuum tube 11. One end of the vacuum tube 14 is connected to the inner cavity of the vacuum tube 11, and the other end of the vacuum tube 14 is flush with the top of the vacuum tube 11. When the medal is placed on the top of the vacuum tube 11, the top end of each vacuum tube 14 can fit exactly on the bottom of the medal, thereby ensuring that the medal remains horizontal after being placed without tilting.

[0037] Among them, a plurality of positioning holes 19 are opened on the top of the fixing frame 4, and the number of the positioning holes 19 and the positioning rods 17 are the same, the diameters are correspondingly equal, and the center of each positioning hole 19 corresponds one-to-one with the center of each positioning rod 17. When the recovery tray 15 is placed on the fixing frame 4, each positioning rod 17 can be aligned with and pass through the corresponding positioning hole 19. At this time, the recovery tray 15 can be positioned by the mutual cooperation between the positioning rods 17 and the positioning holes 19 to prevent its placement position from being offset.

[0038] The positioning groove 16 is an arc-shaped groove structure, and its diameter is equal to the outer diameter of the vacuum cylinder 11. When a pair of recovery plates 15 are spliced ​​together and placed on the fixing frame 4, the wall of the vacuum cylinder 11 can be respectively fitted in the positioning groove 16 on one side of the two recovery plates 15, thereby ensuring that there is no gap between the two recovery plates 15 after splicing.

[0039] Among them, a plurality of counterweight cavities 20 are opened on the base 1, and the counterweight cavities 20 are equidistantly linearly distributed along the length direction of the base 1, and a counterweight block 21 is placed in each counterweight cavity 20. The weight of the base 1 can be increased by the counterweight block 21, so as to improve the balance of the entire fixing device, thereby effectively preventing the fixing device from slipping and displacement during use.

[0040] The circuits, electronic components and chip modules involved in the utility model are all existing technologies and can be fully implemented by those skilled in the art. Needless to say, the content protected by the utility model does not involve improvements to software and methods.

[0041] The standard parts used in the application documents can all be purchased from the market. All the components in this application document can be customized according to the description in the specification and drawings. The specific connection methods of each part adopt mature conventional means such as bolts, rivets, welding, etc. in the prior art. Machinery, parts and equipment all adopt conventional models in the prior art. The electrical components appearing in this article are all electrically connected to the external main controller and 220V AC power, and the main controller can be a conventional known device that controls the LED lamp body, etc.

[0042] The working principle of the utility model is:

[0043] When the utility model is used, the medal to be polished is first placed on the top of the vacuum cylinder 11, and the top end of each vacuum tube 14 is made to fit the bottom of the medal. Then, the vacuum valve 13 is opened and the air in the vacuum cylinder 11 is extracted through the external exhaust fan. At this time, since the air pressure in the vacuum cylinder 11 is reduced, suction will be generated through each vacuum tube 14, so that the medal is firmly adsorbed and fixed on the top of the vacuum cylinder 11 under the action of vacuum. After that, the staff can polish the medal by hand-held sandpaper or other polishing equipment. Compared with the traditional fixing method of fasteners such as screws, it is convenient to polish the edge of the medal, and at the same time, it is also effectively avoided to cause damage to the surface of the medal. During polishing, the movable seat 8 can be rotated to drive the vacuum cylinder 11 to rotate together with the medal to achieve fine adjustment of the fixed angle, so as to achieve the desired effect. The medal can be polished at different positions without removing the medal, which not only greatly improves the work efficiency, but also effectively reduces the workload of the staff. After the angle adjustment is completed, the screw 7 in the threaded hole 6 is tightened until the end of the screw 7 is tightly against the side wall of the movable seat 8 to fix the movable seat 8. A pair of recovery plates 15 are placed on the fixed frame 4. The pair of recovery plates 15 can be spliced ​​into a complete circular plate after being fitted together. When the medal is polished, the fallen debris can be recovered in time through the recovery plate 15, thereby avoiding the difficulty in uniform cleaning after the debris is scattered everywhere. When the entire polishing work is completed, the positioning rod 17 at the bottom of the recovery plate 15 is pulled out of the positioning hole 19 on the surface of the fixed frame 4, and then the recovery plate 15 is lifted off the fixed frame 4 and disassembled, and the debris in the recovery plate 15 can be subsequently cleaned.
