Referring to fig. 1 to 3, an embodiment of the present utility model relates to a sanding machine 100, which includes a housing 1, a driving assembly 2 installed in the housing 1, and a base plate assembly 3 driven by the driving assembly 2, wherein the housing 1 includes a main housing 11 accommodating the driving assembly 2, and an intermediate cover 12 connected to the main housing 11, the intermediate cover 12 is located between the main housing 11 and the base plate assembly 3, and a vibration frame 5 is provided between the intermediate cover 12 and the base plate assembly 3. The floor assembly 3 includes a floor 31 attached to the intermediate cover 12 and sandpaper 32 mounted to the floor 31, the sandpaper 32 being secured to the floor assembly 3 by sandpaper clips 33 on the floor 31. The sander 100 is driven by a driving source to move, and drives a driving shaft (not shown) of the driving assembly 2 to rotate, and the base plate 31 below the driving shaft is provided with sand paper 32 to perform sanding operation under the action of the driving shaft.

In this embodiment, the sander 100 is provided with the external accessory 4, the external accessory 4 is mounted on the middle cover 12, the middle cover 12 includes a first side wall 123 and a second side wall 124 disposed adjacently, an adapter 121 recessed from an end surface of the second side wall 124, and a dust collecting opening 122 penetrating through the adapter 121, and the external accessory 4 is combined with the adapter 121. By providing the adaptor 121 recessed in the end surface of the second side wall 124 of the middle cover 12, the possibility that the complete machine can mount a plurality of external accessories 4 is increased.

The adapter 121 has a base plate 1211, a first connector 1212 connected to the base plate 1211, and a second connector 1213 protruding from an end surface of the first connector 1212, and a locking screw 40 is inserted through the external accessory 4 and the second connector 1213 to fix the external accessory 4 to the middle cover 12. By the above arrangement, the attachment 4 is attached to the intermediate cover 12 by the locking screw 40, and the attachment 4 is firmly attached to the sander 100 and is not easily detached when sanding is performed. In addition, the overall shape of the attachment 4 corresponds to the shape of the adapter 121, which is convenient and quick to install.

The external accessory 4 includes a mounting portion 41 mounted on the second connector 1213 and an adapting portion 42 connected to the mounting portion 41, and the adapting portion 42 abuts against the adapter 121. It should be noted that, the user may select different adapting portions 42 to abut against the adaptor 121, so as to achieve various requirements of dust collection or dust non-collection.

The adapting portion 42 is configured as a dust collecting interface 420, and the dust collecting interface 420 has a flat loop-shaped structure. It should be noted that the dust collecting port 420 is preferably, but not limited to, a flat loop structure, and the flat loop structure is designed in view of the overall structure of the middle cover 12.

Referring to fig. 3 and 4, the sanding machine 100 further includes a dust collecting assembly 200 mounted on the dust collecting interface 420, the dust collecting assembly 200 includes a dust collecting bracket 20 mounted on the dust collecting interface 420, the dust collecting bracket 20 includes a first section 201 mounted on the dust collecting interface 420, a second section 202 connected to the first section 201, and a third section 203 connected to the second section 202, and a line connecting a projection of the second section 202 on a plane of the base plate assembly 3 and a projection of the third section 203 on a plane of the base plate assembly 3 is in a curved transition, so that the installation of the structure is facilitated.

The first section 201 has a similar structure to that of the dust collecting port 420, and can be fitted and firmly mounted together by the friction force of the two sections. In addition, the first section 201 is sleeved on the periphery of the dust collection interface 420, so that dust generated by the sand paper 32 driven by the bottom plate 31 directly enters the dust collection assembly 200 along the dust collection interface 420, and the dust cannot stay at the junction of the dust collection assembly and the dust collection assembly, thereby causing incomplete dust collection.

The curvature of the second section 202 gradually contracts in the direction of the first section 201 to the third section 203. It should be noted that, the third section 203 is configured to match the interface of the dust collector (not shown), and the user does not need to detach the dust collecting bracket 20, but only need to detach the dust collecting bag 30 to mount the dust collector on the third section 203, so as to realize polishing and dust collection, and greatly improve polishing efficiency.

The dust collection assembly 200 further has a dust collection bag 30 mounted to the dust collection holder 20, the dust collection holder 20 further has an engagement portion 204 protruding from a sidewall of the second section 202, and the dust collection bag 30 is coupled to the engagement portion 204. It should be noted that, the dust collecting assembly 200, the dust collecting interface 420, the integrated bracket 20 and the dust collecting bag 30 all adopt detachable structures, the former is the selection of dust collecting and non-dust collecting functions, the latter is the selection of the dust collecting bag 30 and the dust collector, the applicability of the whole machine is wide, and the functionality is stronger. In addition, the maximum curvature of the second section 202 is equal to the inner diameter of the dust bag 30, facilitating a more secure mounting of the dust bag 30 to the dust collection interface 420.

Referring to fig. 5 and 6, the fitting portion 42 is configured as a cover plate 420', and the locking screw 40' is penetrated through the mounting portion 41 and extends to the second connecting member 1213 to fix the cover plate 420' to the middle cover 12. Through the above arrangement, when a user does not want to use the dust collection interface 420 to collect dust, dust generated by polishing the sand paper 32 is directly discharged from the height space formed by the bottom plate 31 and the middle cover 12, so that the polishing of the whole machine to the workpiece instead of the machining is realized. The thickness of the cover plate 420' is equal to that of the adaptor 121, and thus the overall aesthetic property can be achieved.

In the utility model, the sander 100 is provided with the adapter 12 on the second side wall 124 of the middle cover 12, and the adapter 42 on different adapters 12 is selected to realize the installation of various external accessories, so as to meet different requirements of users, and through a simple structure, the dual fusion of dust collection and non-dust collection is realized, and the sander has wide application and stronger functionality.

The present utility model is not limited to the above-described embodiments. Those of ordinary skill in the art will readily appreciate that many alternatives to the sander of the present utility model are possible without departing from the spirit and scope of the present utility model. The protection scope of the present utility model is subject to the claims.
