[0002] Consumables grinding involves an important link in the manufacturing industry. Its technicality and operational complexity make consumables replacement a technical issue that cannot be ignored.

[0003] In the manufacturing industry, especially in the fields of metalworking, woodworking and composite processing, grinding of consumables is a key process.

[0004] Grinding aims to improve the finish, precision and surface quality of workpieces by removing surface materials. However, as the process progresses, the consumables used for grinding (such as grinding wheels, sandpaper or polishing cloth) need to be replaced regularly due to wear. Due to the particularity of workpiece grinding, eccentric shaft grinding is used. Due to the uncertainty of eccentric shaft movement, the grinding consumables can only be replaced by traditional manual labor.

[0025] An automatic consumable replacement device for an eccentric grinding and polishing machine, see Figure 1-Figure 4 , comprising a frame 1, a rotating shaft 11 rotating on the frame 1, a plurality of eccentric shaft grinding heads 12 rotating on the rotating shaft 11, and a consumable 13 capable of being attached to the eccentric shaft grinding heads 12, a driving motor 14 for driving the eccentric shaft grinding heads 12 is installed on the rotating shaft 11, an encoder 15 (not shown in the figure) is installed in the driving motor 14, and a rotating motor 16 for driving the rotating shaft 11 to rotate is provided on the frame 1;

[0026] It also includes a consumable 13 replacement structure for replacing the consumable 13 on the eccentric shaft grinding head 12; the rotation position of the eccentric shaft grinding head 12 is identified by an encoder 15 (not shown in the figure), and based on the replacement position of the consumable 13 on the eccentric shaft grinding head 12 set by the drive motor 14, the drive motor 14 is used to adjust between the rotation position and the replacement position. Based on this, the consumable 13 replacement structure is used to perform operating operations on the eccentric shaft grinding head 12.

[0027] In this embodiment, the rotating shaft 11 is driven by the rotating motor 16 to rotate axially, so that the eccentric shaft grinding head 12 installed on the rotating shaft 11 can face the consumable 13 replacement structure. At this time, the rotation position of the eccentric shaft grinding head 12 is identified by the encoder 15 (not shown in the figure), and based on the replacement position of the consumable 13 on the eccentric shaft grinding head 12 pre-set by the driving motor 14, the driving motor 14 is used to adjust between the rotation position and the replacement position. Based on this, the consumable 13 replacement structure is used to perform operations on the eccentric shaft grinding head 12 to replace the consumable 13 located on the eccentric shaft grinding head 12, thereby realizing autonomous operation, improving grinding efficiency, and reducing safety hazards.

[0028] In this embodiment, eight eccentric shaft grinding heads 12 are arranged on the rotating shaft 11, four of which are located on the same side, and adjacent eccentric shaft grinding heads 12 are cross-arranged on the rotating shaft 11. When the eccentric shaft grinding head 12 needs to replace the consumable 13, the rotating shaft 11 is driven to rotate by the rotating motor 16, so that the eccentric shaft grinding head 12 can face the consumable 13 replacement structure, thereby facilitating the replacement of the consumable 13.

[0029] Specifically, the consumable 13 replacement structure includes a consumable 13 grasping mechanism installed on the frame 1 and a consumable 13 fitting mechanism installed on the frame 1; the consumable 13 grasping mechanism gradually approaches the replacement position until it abuts against the consumable 13 and pulls the consumable 13 away from the eccentric shaft grinding head 12, and the consumable 13 fitting mechanism approaches the replacement position until the consumable 13 is fitted and fixed to the eccentric shaft grinding head 12.

[0030] The replacement of the consumable material 13 is carried out in two steps. First, the old consumable material 13 attached to the eccentric shaft grinding head 12 needs to be removed; second, the new consumable material 13 is attached to the eccentric shaft grinding head 12 .

[0031] To this end, the consumable 13 grabbing mechanism is first used to gradually approach the replacement position until it abuts against the consumable 13 and pulls the consumable 13 away from the eccentric shaft grinding head 12. On this basis, the consumable 13 fitting mechanism is used to gradually approach the replacement position until the new consumable 13 is fitted and fixed to the eccentric shaft grinding head 12, thereby completing the replacement process of the new consumable 13.

[0032] Specifically, the consumable material 13 grabbing mechanism includes a sharpening knife 31 rotating on the frame 1, a rotating shaft 32 installed on the frame 1, and a first driving member 33 driving the rotating shaft 32 to reciprocate.

[0033] Since the old consumable 13 is attached to the eccentric shaft grinding head 12, the first driving member 33 is used to drive the rotating shaft 32 to rotate reciprocatingly, and the rotating shaft 32 drives the grinder 31 to pull the old consumable 13, and the reciprocating rotation can prepare for the next pulling of the old consumable 13 to return.

[0034] In this embodiment, a driving cylinder is used for the first driving member 33 , and the driving shaft of the driving cylinder is connected and driven to the rotating shaft 32 via a connecting shaft 34 , so as to convert the linear motion of the cylinder into the reciprocating rotational motion of the rotating shaft 32 .

[0035] In addition, a pulling cylinder is installed on the driving cylinder. When the sharpening knife 31 abuts against the consumable material 13, the pulling cylinder pulls the driving cylinder, the sharpening knife 31, and the rotating shaft 32 to move linearly as a whole, which helps to separate the consumable material 13.

[0036] Specifically, the frame 1 is provided with a lifting assembly 5 for driving the consumable material 13 laminating mechanism and the eccentric shaft grinding head 12 to move closer to and away from each other.

[0037] Since the eccentric shaft grinding head 12 is mostly used for grinding and polishing workpieces for a long time, the consumable 13 needs to be replaced in time during the intervals between grinding and polishing due to the loss of the consumable 13. When replacing the consumable 13, the consumable 13 fitting mechanism will set a distance between the consumable 13 fitting mechanism and the eccentric shaft grinding head 12 to avoid interference with the workpiece grinding. When the consumable 13 needs to be replaced, the consumable 13 fitting mechanism and the eccentric shaft grinding head 12 need to be driven closer to each other through the lifting component 5. After the consumable 13 is replaced, the lifting component 5 is used to drive the consumable 13 fitting mechanism and the eccentric shaft grinding head 12 to move away from each other.

[0038] Specifically, the lifting assembly 5 includes a lifting platform 51 sliding on the frame 1, the rotating shaft 11 is installed on the lifting platform 51, and the frame 1 is provided with a slide rail for the lifting platform 51 to slide. The lifting platform 51 is driven by a linear module arranged on the frame 1 to slide along the slide rail to approach and move away from the consumable 13 replacement structure.

[0039] The present embodiment is provided with a lifting platform 51 , which is driven by a linear module to move along the slide rail, and the slide rail is arranged along a direction close to the consumable material 13 replacement structure.

[0040] Specifically, the consumable 13 bonding mechanism includes a gantry support frame 41 installed on the frame 1, a barrel 42 provided on the gantry support frame 41, and a push rod 43 that passes through and moves in the barrel 42. A second driving member 44 for driving the push rod 43 to move is provided on the gantry support frame 41. The barrel 42 is filled with a plurality of consumables 13 to be replaced, and one end of the barrel 42 away from the second driving member 44 is opposite to the replacement position.

[0041] In this embodiment, the push rod 43 is driven by the second driving member 44 to move through the barrel 42. A plurality of consumables 13 to be replaced are filled in the barrel 42 in advance. The consumables 13 to be replaced are pushed by the push rod 43 so that the consumables 13 to be replaced gradually approach until they are attached to the eccentric shaft grinding head 12 on the replacement position, thereby completing the automatic loading process step of the consumables 13 to be replaced.

[0042] The eccentric shaft grinding head 12 is provided with a plurality of blind holes, and the consumable 13 is inserted into the blind holes for position limiting and fixing, thereby completing the connection and fixing between the consumable 13 and the eccentric shaft grinding head 12 .

[0043] The above embodiments are merely explanations of the present invention and are not limitations of the present invention. After reading this specification, those skilled in the art may make modifications to the embodiments without any creative contribution as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
