Description

Technical Field

[0001] This utility model belongs to the field of sanding technology, specifically a swing-type sander. Background Technology

[0002] A sander is a tool used to grind and polish the surface of various materials, making the surface smoother and flatter.

[0003] A oscillating sander is a type of sander that features sandpaper mounted on a oscillating workhead. The reciprocating motion of the workhead drives the sandpaper to move back and forth at a certain frequency and amplitude to polish the surface of the object. After a period of sanding, the surface of the sandpaper becomes damaged and needs to be replaced. However, existing oscillating sanders require removing the used sandpaper and installing new sandpaper, which is inconvenient.

[0004] Therefore, this utility model provides a swing-type sander. Utility Model Content

With the above structure, when polishing the surface of an object, the debris generated during polishing can be cleaned up, reducing the impact of debris remaining between the object and the sandpaper on the polishing effect, and also reducing the occurrence of debris flying into the air and causing pollution to the working environment.

[0009] Preferably, the sidewall of the sandpaper is fixed with multiple limiting bands; the bottom and sidewall of the pressure plate are provided with limiting grooves; through the above structure, it is difficult for the sandpaper to move perpendicular to the direction of the limiting groove, reducing the occurrence of sandpaper offset under the pressure plate, improving the convenience of sandpaper adjustment, and reducing the impact of sandpaper offset on the sanding effect.

[0010] Preferably, a roller is rotatably connected to the middle of the eccentric rod; the roller is located in the middle of the first connecting groove; through the above structure, the sliding friction between the eccentric rod and the first connecting groove can be transformed into rolling friction, reducing the wear of the component and improving the service life of the component.

[0024] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0025] Example:

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] like Figures 1 to 5As shown, an embodiment of the present invention provides a swing-type sander, comprising a machine body 1; a partition 12 is fixedly connected inside the machine body 1; a motor 13 is fixedly connected to the bottom of the partition 12; an eccentric rod 14 is fixedly connected to the output end of the motor 13; a connecting rod 15 is slidably connected to the middle of the machine body 1; a first connecting groove 16 is formed in the middle of the connecting rod 15; the other end of the eccentric rod 14 is slidably connected to the middle of the first connecting groove 16; a pressure plate 17 is fixedly connected to the bottom of the connecting rod 15; the machine... A pair of support frames 18 are symmetrically fixed to the two side walls of body 1; a mounting shaft 19 is rotatably connected to the middle of the support frame 18; an elastic rope 110 is fixed to one end of the mounting shaft 19; a limit plate 111 is fixed to the other end of the elastic rope 110; the limit plate 111 is slidably connected to the end of the mounting shaft 19; multiple slots 112 are provided on the side wall of the support frame 18; sandpaper 113 is detachably installed in the middle of the mounting shaft 19; during operation, the two sides of the sandpaper 113 are... Each end is connected to a pair of mounting shafts 19, and the middle of the sandpaper 113 passes around the bottom of the pressure plate 17. When in use, the motor 13 is started and the pressure plate 17 is driven to swing back and forth through the cooperation of the eccentric rod 14 and the connecting rod 15, so that the sandpaper 113 under the pressure plate 17 swings to a certain extent. When the sandpaper 113 becomes dull and the sand particles fall off due to long-term use, the limiting plate 111 can be pulled to make the limiting plate 111 leave the corresponding slot 112. Then the mounting shaft 19 is rotated to make the sandpaper 113 roll up and unroll. After completion, the limiting plate 111 is released and falls into the corresponding slot 112 so that the mounting shaft 19 will not easily rotate again. Thus, the intact sandpaper 113 can be placed under the pressure plate 17 for use. With the above structure, the unworn sandpaper 113 can be quickly installed in the working position after the sandpaper 113 is worn, saving working time and improving the ease of use of the device.

[0028] like Figures 1 to 4 As shown, a pair of clamping plates 2 are symmetrically fixed to the top of the pressure plate 17; clamping rods 21 are rotatably connected to the side walls of the clamping plates 2; multiple sets of second connecting grooves 22 are opened on the top of the clamping rods 21 of the clamping plates 2; a pin plate 23 is detachably installed in the middle of each set of second connecting grooves 22; during operation, when the pressure plate 17 swings back and forth due to the rotation of the eccentric rod 14, the sandpaper 113 may slide relative to the pressure plate 17. Therefore, after adjusting the position of the sandpaper 113, the clamping rods 21 are rotated to make the clamping rods 21 and the clamping plates... 2. The sandpaper 113 is clamped in the middle, and then multiple pin plates 23 are inserted into multiple sets of second connecting grooves 22 so that the clamping rod 21 and the clamping plate 2 will not easily separate. At this time, the position of the sandpaper 113 under the pressure plate 17 is fixed, so that the sandpaper 113 can swing synchronously and rub the object when the pressure plate 17 swings back and forth. Through the above structure, when polishing the surface of the object, the relative sliding between the sandpaper 113 and the pressure plate 17 can be reduced, which would reduce the polishing effect on the surface of the object.

[0029] like Figures 1 to 6 As shown, a collection box 3 is fixedly connected to the side wall of the machine body 1; the collection box 3 communicates with the upper space of the partition 12; a connecting pipe 31 is fixedly connected to the top of the machine body 1; a filter collection cylinder 32 is installed on the top of the connecting pipe 31; an air extractor 33 is installed on the top of the filter collection cylinder 32; during operation, when sanding the surface of an object, the air extractor 33 can be activated to continuously draw air from the bottom of the collection box 3 into the collection box 3. At the same time, the flowing air will carry the debris that has been ground off the surface of the object into the collection box 3. After the debris enters the filter collection cylinder 32, it will separate from the flowing air and remain inside the filter collection cylinder 32. Through the above structure, the debris generated during sanding of the surface of an object can be cleaned up, reducing the impact of debris remaining between the object and the sandpaper 113 on the sanding effect, and reducing the occurrence of debris flying into the air and causing pollution to the working environment.

[0030] like Figure 1 As shown in the figure, multiple limiting bands 4 are fixed to the side wall of the sandpaper 113; the bottom and side wall of the pressure plate 17 are provided with limiting grooves 41; during operation, when the sandpaper 113 is installed under the pressure plate 17, the multiple limiting bands 4 are placed inside the limiting grooves 41, thereby reducing the occurrence of the sandpaper 113 shifting under the pressure plate 17. Through the above structure, it is difficult for the sandpaper 113 to move perpendicular to the direction of the limiting grooves 41, reducing the occurrence of the sandpaper 113 shifting under the pressure plate 17, improving the adjustment convenience of the sandpaper 113, and reducing the impact of the sandpaper 113 shifting on the sanding effect.

[0031] like Figures 1 to 3 As shown, a roller 5 is rotatably connected to the middle of the eccentric rod 14; the roller 5 is located in the middle of the first connecting groove 16; during operation, the above structure can convert the sliding friction between the eccentric rod 14 and the first connecting groove 16 into rolling friction, thereby reducing the wear of the component and improving its service life.

[0032] like Figures 1 to 6 As shown, multiple brushes 6 are fixed to the bottom of the collection box 3; the multiple brushes 6 are densely distributed at the bottom of the collection box 3; during operation, when the collection box 3 absorbs the grinding debris near the bottom of the pressure plate 17, the bottom of the multiple brushes 6 will contact the surface of the object being ground and reduce the occurrence of external air passing through the multiple brushes 6, thereby increasing the suction force of the bottom of the collection box 3 in the direction facing the pressure plate 17. Through the above structure, the suction force can be more concentrated when absorbing the grinding debris, thus improving the cleaning effect of the debris.

[0033] like Figure 3As shown, the sandpaper 113 is segmented; each segment of sandpaper 113 has a different grit number; through the above structure, sandpaper 113 with different grit numbers can be easily installed at the bottom of the pressure plate 17, thereby facilitating multiple polishing of the object surface and reducing the inconvenience and time consumption caused by changing sandpaper 113 with different grit numbers.

[0034] During operation, the two ends of the sandpaper 113 are connected to a pair of mounting shafts 19, and the middle of the sandpaper 113 is arranged to pass over the bottom of the pressure plate 17. When in use, the motor 13 is started, and the pressure plate 17 is driven to swing back and forth through the cooperation of the eccentric rod 14 and the connecting rod 15, so that the sandpaper 113 under the pressure plate 17 swings to a certain extent. When the sandpaper 113 becomes dull and the abrasive particles fall off due to long-term use, the limiting plate 111 can be pulled to disengage from the corresponding slot 112. Then, the mounting shaft 19 is rotated to move the sandpaper... 113 performs winding and unwinding. After completion, the limiting plate 111 is released, allowing it to fall into the corresponding slot 112, preventing the mounting shaft 19 from rotating easily. This allows the intact sandpaper 113 to be placed under the pressure plate 17 for use. When the pressure plate 17 swings back and forth due to the rotation of the eccentric rod 14, the sandpaper 113 may slide relative to the pressure plate 17. Therefore, after adjusting the position of the sandpaper 113, the clamping rod 21 is rotated to clamp the middle of the sandpaper 113 with the clamping rod 21 and the clamping plate 2. Then, multiple pins are... Plate 23 is inserted into multiple sets of second connecting slots 22 to prevent clamping rod 21 and clamping plate 2 from easily separating. At this time, the position of sandpaper 113 under pressure plate 17 is fixed, so that sandpaper 113 can swing synchronously and rub the object when pressure plate 17 swings back and forth. When sanding the surface of the object, the air pump 33 is started to allow air near the bottom of collection box 3 to continuously enter the collection box 3. At the same time, the flowing air will carry the debris that is worn off the surface of the object into the collection box 3, and the debris will enter the filter collection cylinder. The sandpaper 113 separates from the flowing air inside the filter collection cylinder 32 and remains inside the filter collection cylinder 32. When the sandpaper 113 is installed below the pressure plate 17, multiple limiting bands 4 are placed inside the limiting groove 41 to reduce the occurrence of the sandpaper 113 shifting below the pressure plate 17. When the collection box 3 absorbs the sanding debris near the bottom of the pressure plate 17, the bottom of multiple brushes 6 will contact the surface of the object being sanded and reduce the occurrence of external air passing through multiple brushes 6, thereby increasing the suction force of the bottom of the collection box 3 in the direction facing the pressure plate 17.

[0035] The above embodiments merely illustrate specific implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
