Description

Technical Field

[0001] This application relates to the field of furniture polishing devices, and more particularly to a partial polishing device for furniture repair. Background Technology

[0002] Furniture sanding is an important furniture repair process. When furniture is partially damaged during use, it is usually repaired. There are many ways for workers to repair furniture, but after the repair is completed, in order to make the repaired surface smoother and more beautiful, the repaired area will be sanded.

[0003] Existing furniture repair and sanding devices consist of a support cylinder, a rotating shaft, a sanding head, and a drive mechanism. Sanding operation is simple and can quickly complete furniture repair. However, existing furniture repair and sanding devices still have certain drawbacks. Since the repair area may vary for different pieces of furniture (requiring different sized sanding heads), and the sanding heads wear down after repeated use, workers need to replace them as needed. Traditionally, the connection between the sanding head and the rotating shaft is usually secured with multiple bolts, requiring tools to remove the sanding head when replacing it, and these bolts are easily lost. Therefore, this application proposes a partial sanding device for furniture repair. Utility Model Content

[0028] Example

[0029] like Figures 1-4As shown, this application discloses a furniture repair and partial sanding device, comprising a support sleeve 1 and a servo motor 3 installed at its end, the servo motor 3 being electrically connected to an external power source. The output shaft of the servo motor 3 is fixedly connected to a rotating shaft 6 that passes through the support sleeve 1, and a sanding head 5 is provided on one side of the rotating shaft 6. A support sleeve is fixedly connected to the side wall of the support sleeve 1, and a handle 2 is fixedly connected to the side wall of the support sleeve. A switch button is provided on the handle 2, and the switch button is electrically connected to the servo motor 3.

[0030] It also includes a support ring 4 fixedly connected to the end of the support sleeve 1, and a connecting plate 7 located inside the support ring 4 is fixedly connected to one end of the rotating shaft 6. A locking mechanism 9 is provided on the connecting plate 7, and a connecting piece 10 that cooperates with the locking mechanism 9 is provided on the inner end of the grinding head 5.

[0031] Specifically, the locking mechanism 9 includes a locking plate 92 slidably connected to the connecting plate 7, and a sliding groove 91 formed at the end of the connecting plate 7. The locking plate 92 is L-shaped and can be completely housed within the sliding groove 91. The connecting member 10 includes a connecting sleeve 101 fixedly connected to the inner end of the grinding head 5. The inner wall of the connecting sleeve 101 has a locking groove 102. During grinding, the protrusion of the locking plate 92 is inserted into the locking groove 102, thereby locking the connecting sleeve 101.

[0032] The support ring 4 has a flat portion 41 on its side wall, and a bolt 93 is vertically threaded onto the flat portion 41. The inner end of the bolt 93 is rotatably connected to the locking plate 92, and the outer end of the bolt 93 is fixedly connected to a torsion block. A support bearing is embedded on the outer surface of the locking plate 92, and the inner end of the bolt 93 is fixedly connected to the inner ring of the support bearing. The state of the locking plate 92 can be controlled by rotating the bolt 93, allowing the protrusion of the locking plate 92 to be inserted into or moved away from the locking groove 102.

[0033] It should be noted that the inner groove of the connecting sleeve 101 matches the connecting plate 7, and the size of the locking groove 102 matches the size of the protrusion of the locking plate 92. This ensures a stable connection between the grinding head 5 and the rotating shaft 6.

[0034] Furthermore, an annular groove is provided at the outer end of the support ring 4, and a limiting ring 8 is rotatably connected within the annular groove. When the connecting sleeve 101 is connected to the connecting plate 7, the inner end of the connecting sleeve 101 abuts against the outer end of the limiting ring 8. After the grinding head 5 is installed, the inner end of the connecting sleeve 101 abuts against the outer end of the limiting ring 8, which provides axial support and limits for the connecting sleeve 101 without affecting its rotation.

[0035] The working principle of this embodiment is as follows: A connecting plate 7 is fixedly connected to the mounting end of the support sleeve 1. A locking mechanism 9 is provided on the connecting plate 7, and a connecting piece 10 is provided at the connecting end of the grinding head 5. When using this device for grinding, the protrusion of the locking plate 92 is engaged in the locking groove 102. When it is necessary to remove the grinding head 5 later, to replace the model of the grinding head 5 or to replace it with a new grinding head 5, the bolt 93 is rotated to push the locking plate 92 into the sliding groove 91 (at this time, the protrusion of the locking plate 92 disengages from the locking groove 102, see reference). Figure 2 The grinding head 5 can be removed to one side (the grinding head 5 and the connecting part 10 are replaced simultaneously). The whole process is simple and quick. When installing the grinding head 5, the connecting sleeve 101 is placed on the end of the connecting plate 7 (before placing it, observe that the locking groove 102 is located on one side of the locking plate 92). Then, the bolt 93 is rotated in the opposite direction to move the locking plate 92 a certain distance to the outside of the slide groove 91, so that the protrusion of the locking plate 92 is inserted into the locking groove 102, thereby completing the locking of the connecting sleeve 101.

[0036] By rotating the limiting ring 8 at one end of the support ring 4, the inner end of the connecting sleeve 101 of the grinding head 5 abuts against the limiting ring 8 when the grinding head 5 is in the installed state. This not only supports and positions the connecting sleeve 101, but also does not hinder the rotation of the connecting sleeve 101 during grinding.

[0037] When sanding furniture, the servo motor 3 is started. The output shaft of the servo motor 3 rotates, which drives the rotating shaft 6 to rotate. The rotating shaft 6 rotates, which drives the connecting plate 7 to rotate. In turn, the connecting piece 10 drives the sanding head 5 to rotate (the sanding surface of the sanding head 5 is aligned with the furniture repair surface), thus completing the sanding of the furniture.

[0038] The above specific embodiments are merely preferred embodiments of this application. Based on the technical solutions of this application and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments. The above specific embodiments are merely explanations of this application and are not limitations on this application.
