Description

Sanding machine

Technical Field

The utility model belongs to the technical field of the equipment of polishing and specifically relates to a grinder is related to.

Background

The sander is widely applied to wall or ground polishing as a common handheld electric tool. The working chassis of the sander is provided with sanding materials such as sand paper and the like, and is connected with the driving device. When the abrasive paper polishing machine works, the driving device drives the working chassis device, so that the attached abrasive paper correspondingly rotates, the surface of a workpiece needing polishing is continuously polished, and the workpiece is smooth and flat.

The existing sander comprises a shell, a motor and a transmission shaft are arranged in the shell, the motor and the transmission shaft are in interference fit, time and labor are wasted during installation and later-period maintenance, and the working efficiency is reduced.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is: in order to solve current grinder and include the casing, set up motor and transmission shaft in the casing, be interference fit between motor and the transmission shaft, it is more time-consuming and laborious when installation and later maintenance, reduce work efficiency's problem, provide a grinder now.

The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a sander, includes casing, transmission shaft, work bottom plate, be provided with drive arrangement in the casing, work bottom plate sets up on the casing, the transmission shaft rotates and sets up in the casing, profile connection between transmission shaft and the drive arrangement's the output. The interference fit between the output end of the original driving device and the transmission shaft is changed into the mode that the output end of the driving device is connected with the transmission shaft through the molded surface, so that the driving device is convenient and quick to install and maintain between the driving device and the transmission shaft, and the working efficiency is improved.

The fan blade is fixedly connected to the transmission shaft and located in the cavity, and a through hole communicated with the cavity is formed in the bottom of the working bottom plate.

Further, a dust suction box is arranged on the discharge port of the shell.

Furthermore, the driving device is a servo motor, the cross section of an output shaft at one end of the servo motor is D-shaped, a polygonal hole matched with the output shaft on the servo motor is formed in one end of the transmission shaft, and the output shaft of the servo motor is inserted into the polygonal hole.

The utility model has the advantages that: the utility model discloses sander when using, through changing the interference fit between original drive arrangement output and the transmission shaft into drive arrangement output and transmission shaft between the profile be connected, like this between drive arrangement and transmission shaft installation with maintain convenient and fast relatively, improved work efficiency, avoided current sander to include the casing, set up motor and transmission shaft in the casing, be interference fit between motor and the transmission shaft, relatively take time and take a lot of work when installation and later maintenance, reduce work efficiency's problem.

Drawings

The present invention will be further explained with reference to the drawings and examples.

Fig. 1 is a front view of the present invention;

FIG. 2 is a cross-sectional view A-A of FIG. 1;

FIG. 3 is an enlarged view of portion B of FIG. 2;

fig. 4 is a schematic three-dimensional structure diagram of the middle transmission shaft of the present invention.

In the figure: 1. the fan comprises a shell, 101, a hollow cavity, 102, a discharge port, 2, a transmission shaft, 201, a polygonal hole, 3, a working bottom plate, 301, a through hole, 4, a fan blade, 5, a dust collection box, 6 and a driving device.

Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.

Examples

As shown in fig. 1-4, a sander comprises a housing 1, a transmission shaft 2 and a working bottom plate 3, wherein a driving device 6 is arranged in the housing 1, the working bottom plate 3 is arranged in the housing 1, the transmission shaft 2 is rotatably arranged in the housing 1, and the transmission shaft 2 is connected with the output end of the driving device 6 in a molded manner.

Still include fan blade 4, set up cavity body 101 between casing 1 and the work bottom plate 3, set up the discharge port 102 with cavity body 101 intercommunication on the casing 1, fan blade 4 fixed connection is on transmission shaft 2, fan blade 4 is located cavity body 101, the through-hole 301 with cavity body 101 intercommunication is seted up to work bottom plate 3 bottom.

The housing 1 is provided with a dust box 5 on the discharge port 102.

The driving device 6 is a servo motor, the cross section of an output shaft at one end of the servo motor is D-shaped, a polygonal hole 201 matched with the output shaft on the servo motor is formed in one end of the transmission shaft 2, and the output shaft of the servo motor is inserted into the polygonal hole 201.

When the sander is used, a switch is arranged on a shell 1, a storage battery is arranged on the shell 1, the storage battery, the switch and a servo motor are connected in series, the servo motor is controlled to operate through the switch, the servo motor drives a fan blade 4 on a transmission shaft 2 to rotate through the transmission shaft 2, grinding paper is adhered to the bottom of a working bottom plate 3, when the working bottom plate 3 is sanded, the fan blade 4 sucks ground dust into a cavity body 101 through a through hole 301 on a working floor, and the dust is discharged into a dust suction box 5 through a discharge port 102 of the shell 1;

when maintaining or installing, at first aim at servo motor's input with the one end multilateral hole 201 of transmission shaft 2 and insert, can make things convenient for quick like this and install between servo motor and the transmission shaft 2, changed interference fit between original servo motor and the transmission shaft 2, and lead to the problem that the installation is wasted time and energy between servo motor and the transmission shaft 2, improved work efficiency.

In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
