Description

Technical Field

[0001] The utility model relates to the field of polishing machines, in particular to a polishing head for metal parts and a polishing machine. Background Art

[0002] A Chinese patent with the publication number CN201815973U discloses an inner hole polishing brush, which includes a skeleton. A number of nylon filaments are circumferentially arranged on the outer wall of the skeleton, and a number of the nylon filaments on the outer wall of the skeleton are arranged at intervals along the extending direction of the skeleton. Abrasive balls for polishing are arranged at one ends of each of the nylon filaments away from the skeleton.

[0003] In the above structure, the abrasive balls can be used to polish metal parts. However, the abrasive balls will gradually wear during use, resulting in a decrease in the polishing effect and efficiency of the metal parts. At this time, the abrasive balls need to be replaced. However, it is rather troublesome to only replace the abrasive balls in the above structure. Summary of the Utility Model

[0004] In view of the disadvantages that the abrasive balls in the prior art will gradually wear during use, resulting in a decrease in the polishing effect and efficiency of the metal parts, and it is rather troublesome to only replace the abrasive balls in the above structure, the utility model provides a polishing head for metal parts and a polishing machine with convenient replacement of polishing parts.

[0005] To solve the above technical problems, the utility model is solved by the following technical solutions:

[0006] A polishing head for metal parts includes a polishing head body. The polishing head body includes a mounting post and at least one mounting plate circumferentially arranged on the outer wall of the mounting post. Brush hairs for polishing metal parts are arranged on the mounting plate. A detachable structure for mounting the mounting plate to the mounting post or detaching the mounting plate from the mounting post is arranged between the mounting post and the mounting plate. The detachable structure includes an open-ended mounting groove arranged on the mounting post for the mounting plate to be inserted into, and an anti-detaching component arranged near the opening of the mounting groove for restricting the mounting plate from disengaging from the mounting groove.

[0007] With the above scheme, the mounting groove can be used for the mounting plate equipped with brush hairs to be inserted therein. When the mounting plate is inserted into the mounting groove, the position of the mounting plate inserted into the mounting groove can be limited by the arranged anti-detaching component, thereby reducing the probability of disengaging from the mounting groove. At the same time, when the brush hairs are worn after long-term use and need to be replaced, only the limit of the anti-detaching component on the mounting plate needs to be released at this time, and then the mounting plate can be detached from the mounting groove for replacement.

[0008] Preferably, the anti - detachment component includes a blocking block disposed on the inner wall of the installation groove near the opening for blocking the installation plate inserted into the installation groove. An elevating component is provided on the installation column for driving the blocking block to extend out to block the installation plate or descend to allow the installation plate to be inserted into the installation groove.

[0009] With the above - mentioned solution, the elevating component can drive the blocking block to move up and down in the installation groove. When the elevating component drives the blocking block to descend, the installation plate can be inserted into the installation groove at this time. When the bristles on the installation plate are worn after long - term use, the elevating component can be used to drive the blocking block to descend, and at this time, the installation plate can be removed from the installation groove for replacement.

[0010] Preferably, the elevating component includes a concave hole recessed at one end of the installation column near the opening of the installation groove. A through - slot is provided on the inner wall of the installation groove and extends vertically towards the concave hole for the blocking block to pass through. A pushing component is provided in the concave hole for driving the blocking block to partially insert into the installation groove after passing through the through - slot from the concave hole or for driving the end of the blocking block near the installation groove to completely retract into the through - slot.

[0011] Preferably, the pushing component includes a driving block inserted in the middle of the concave hole. The driving block includes an ascending section for driving the blocking block to rise, a descending section with a height lower than that of the ascending section for driving the blocking block to descend, and an inclined connecting section for connecting the ascending section and the descending section. A slot is provided in the concave hole for the descending section and the connecting section to be inserted into. When the driving block is inserted towards the slot, the surface of the blocking block gradually moves from the descending section through the connecting section to the ascending section, and the blocking block rises and partially inserts into the installation groove; when the driving block moves away from the slot, the blocking block moves from the ascending section through the connecting section to the descending section, and the blocking block descends and retracts into the through - slot.

[0012] With the above - mentioned solution, when the descending section moves towards the inside of the slot, the blocking block will move from the descending section to the ascending section at this time. Because the height of the descending section is lower than that of the ascending section, the blocking block will gradually rise through the through - slot and insert into the installation groove, thereby limiting the installation plate inserted into the installation groove; when the descending section moves away from the inside of the slot, the blocking block will move from the ascending section to the descending section at this time. Because the height of the descending section is lower than that of the ascending section, the blocking block will gradually descend and retract into the through - slot, and at this time, the installation plate can be removed from the installation groove for replacement.

[0013] Preferably, a pulling component is provided on the driving block for pulling the blocking block to automatically descend when the driving block moves away from the slot.

[0014] Preferably, the pulling member includes a pulling block provided at one end of the blocking block close to the driving block, and a sliding groove provided on the driving block with an opening at one end close to the descending section and extending from the descending section into the ascending section for the pulling block to slide therein.

[0015] With the above solution, when the descending section is inserted into the insertion slot, at this time the pulling block will move from the sliding groove at the descending section to the sliding groove on the ascending section. Since the height of the descending section is lower than that of the ascending section, when the pulling block displaces from the sliding groove on the descending section to the sliding groove on the ascending section, the pulling block will move upward. At this time, a part of the blocking block will be inserted into the installation groove to limit the installation plate, reducing the probability of it coming out of the installation groove; when the descending section moves away from the slot, at this time the pulling block will displace from the sliding groove on the ascending section to the sliding groove of the descending section. At this time, the pulling block will pull the blocking block downward, and at this time the blocking block will retract into the through groove, and the installation plate can be inserted into the installation groove.

[0016] Preferably, a limiting member is provided at the concave hole for pushing the descending section and the connecting section into the insertion slot and reducing the probability of the driving block coming out of the concave hole.

[0017] Preferably, the limiting member includes a screw cap provided at the concave hole. The outer wall of the screw cap is threadedly connected to the inner wall of the concave hole. When a part of the screw cap is inserted into the concave hole, one end close to the driving block abuts against the driving block.

[0018] With the above solution, when the screw cap is screwed into the concave hole, it can abut against the surface of the driving block. As the screw cap is screwed in, the descending section and the connecting section on the driving block will be pushed by the screw cap and gradually inserted into the inside of the slot. At the same time, when the screw cap is installed in the concave hole, it can also reduce the probability of the driving block coming out of the concave hole.

[0019] A polishing machine includes a polishing machine body and the above metal part polishing head.

[0020] With the above solution, installing the metal part polishing head on the polishing machine enables the polishing machine to drive the metal part polishing head to rotate, so that the metal part polishing head can polish and grind the metal part.

[0021] Since the present utility model adopts the above technical solutions, it has remarkable technical effects: the installation groove provided can allow the installation plate equipped with bristles to be inserted therein. When the installation plate is inserted into the installation groove, the position of the installation plate inserted into the installation groove can be limited by the provided anti-disengagement member, thereby reducing the probability of it coming out of the installation groove. At the same time, when the bristles are worn after long-term use and need to be replaced, at this time, only need to release the limit of the anti-disengagement member on the installation plate, and at this time the installation plate can be removed from the installation groove for replacement.

[0035] Embodiment

[0036] A metal part polishing head and a polishing machine, refer to Figures 1 - 2, including a polishing machine body 1 (the polishing machine body in this embodiment is a drill) and a polishing head body installed on the polishing machine body 1. The polishing head body includes a mounting post 2 and at least one mounting plate 3 circumferentially arranged on the outer wall of the mounting post 2. In this embodiment, 4 mounting plates 3 are provided. Brush hairs 5 for polishing metal parts are arranged on the mounting plates 3. A detachable structure for mounting the mounting plate 3 to the mounting post 2 or detaching the mounting plate 3 from the mounting post 2 is provided between the mounting post 2 and the mounting plate 3. The detachable structure includes an open-ended mounting groove 4 provided on the mounting post 2 for the mounting plate 3 to be inserted into, and an anti-detachment component provided near the opening of the mounting groove 4 for restricting the mounting plate 3 from slipping out of the mounting groove 4. In this embodiment, the cross-sectional shapes of the mounting plate 3 and the mounting groove 4 are convex-shaped.

[0037] Reference Figures 3 - 11 , the anti-detachment component includes a blocking block 6 provided on the inner wall of the mounting groove 4 near the opening for blocking the mounting plate 3 inserted into the mounting groove 4. A lifting component for driving the blocking block 6 to extend out to block the mounting plate 3 or lower to allow the mounting plate 3 to be inserted into the mounting groove 4 is provided on the mounting post 2. The lifting component includes a concave hole 8 recessed at one end of the mounting post 2 near the opening of the mounting groove 4. A through groove 7 vertically extending in the direction of the concave hole 8 is provided on the inner wall of the mounting groove 4 for the blocking block 6 to pass through. A pushing component for driving the blocking block 6 to partially insert into the mounting groove 4 after passing through the through groove 7 from the concave hole 8 or driving the end of the blocking block 6 near the mounting groove 4 to completely retract into the through groove 7 is provided in the concave hole 8. The pushing component includes a driving block 9 inserted in the middle of the concave hole 8. The driving block 9 includes a rising section 901 for driving the blocking block 6 to rise, a descending section 902 with a height lower than the rising section 901 for driving the blocking block 6 to descend, and an inclined connecting section 903 for connecting the rising section 901 and the descending section 902. A slot 10 for the descending section 902 and the connecting section 903 to be inserted into is provided in the concave hole 8. When the driving block 9 is inserted into the slot 10 direction, the surface of the blocking block 6 gradually displaces from the descending section 902 through the connecting section 903 to the rising section 901, and the blocking block 6 rises and partially inserts into the mounting groove 4. When the driving block 9 moves away from the slot 10 direction, the blocking block 6 displaces from the rising section 901 through the connecting section 903 to the descending section 902, and the blocking block 6 descends and retracts into the through groove 7. A guiding inclined surface 14 for facilitating the displacement of the pulling block 11 from the sliding groove 12 on the descending section 902 to the sliding groove 12 on the rising section 901 is provided at one end of the pulling block 11 close to the sliding groove 12.

[0038] Reference Figures 10 - 11, a pulling component is provided on the driving block 9, which pulls the blocking block 6 to automatically descend when the driving block 9 moves away from the slot 10. The pulling component includes a pulling block 11 provided at one end of the blocking block 6 close to the driving block 9 and a sliding slot 12 provided on the driving block 9 with an opening at one end close to the descending section 902 and extending from the descending section 902 into the ascending section 901 for the pulling block 11 to slide therein.

[0039] Reference Figures 3 - 9 , a limiting component is provided at the concave hole 8 for pushing the descending section 902 and the connecting section 903 into the slot 10 and reducing the probability of the driving block 9 disengaging from the concave hole 8. The limiting component includes a rotary cover 13 provided at the concave hole 8, the outer wall of the rotary cover 13 is threadedly connected to the inner wall of the concave hole 8, and when a part of the rotary cover 13 is inserted into the concave hole 8, one end close to the driving block 9 abuts against the driving block 9.

[0040] Specific disassembly and assembly process: When the mounting plate 3 with the bristles 5 needs to be mounted on the mounting post 2, first, the rotary cover 13 is unscrewed from the concave hole 8. Then, the driving block 9 is pulled outwards, so that the pulling block 11 below the blocking block 6 is displaced from the sliding slot 12 at the ascending section 901 of the driving block 9 to the sliding slot 12 at the descending section 902. Since the height of the descending section 902 is lower than that of the ascending section 901, when the pulling block 11 moves from the ascending section 901 to the descending section 902, it will pull the blocking block 6 to descend. At this time, the movement of the blocking block 6 close to the mounting slot 4 will completely retract into the through slot 7. At this time, the mounting plate 3 with the bristles 5 can be inserted into the mounting slot 4. After the mounting plate 3 is inserted into the mounting slot 4, the rotary cover 13 can be screwed into the concave hole 8. As the rotary cover 13 is screwed in, one end of the rotary cover 13 close to the driving block 9 will abut against the driving block 9. At this time, the rotary cover 13 will push the driving block 9 towards the slot 10, so that the pulling block 11 is displaced from the sliding slot 12 at the descending section 902 to the sliding slot 12 at the ascending section 901. Since the height of the descending section 902 is lower than that of the ascending section 901, when the pulling block 11 is displaced from the descending section 902 to the ascending section 901, the blocking block 6 will move upwards through the through slot 7 and insert into the mounting slot 4. At this time, the blocking block 6 will limit the mounting plate 3 inserted into the mounting slot 4 and reduce the probability of it disengaging from the mounting slot 4; the movement process of other blocking blocks 6 is the same as that of the above-mentioned blocking block 6, and since multiple blocking blocks 6 are all provided on the driving block 9, the driving block 9 can drive multiple blocking blocks 6 to perform lifting and lowering movements simultaneously.

[0041] The above are only the preferred embodiments of the present utility model, and the protection scope of the present utility model is not limited to the above embodiments. All technical solutions falling within the concept of the present utility model belong to the protection scope of the present utility model. It should be noted that for those of ordinary skill in the art, several improvements and refinements made without departing from the principle of the present utility model should also be regarded as within the protection scope of the present utility model.
