Problems solved by technology

There are sharp barbed or blade-like serrations around the disk of the circular saw. If it is not protected at ordinary times, it is easy to cause harm to the human body.
In addition, the circular saw will splash a lot of waste during the working process. If it is not protected, it will cause the waste to splash everywhere. On the one hand, it is difficult to clean, and on the other hand, the waste in the air will cause damage to the human respiratory tract.

Embodiment 1

[0033] As an embodiment of the present invention, the drive unit includes a rack 171 provided on the outer ring surface of the sleeve 17 and a gear 183 rotatably provided on the guide sleeve 18, and the gear 183 is driven to rotate by the drive element. The driving element is a motor, and the gear 183 forms a transmission cooperation with the motor main shaft through a reduction gear set. The motor can realize the automatic switching of the protective cover between the two stations without manual operation.

Embodiment 2

[0035] As an embodiment of the present invention, the drive unit includes a rack 171 provided on the outer ring surface of the sleeve 17 and a gear 183 rotatably provided on the guide sleeve 18, and the gear 183 is driven to rotate by the drive element. The driving element is a hand wheel 182 rotated on the guide sleeve 18 , and the gear 183 forms a transmission cooperation with the hand wheel 182 through a reduction gear set 181 . The hand wheel can realize the manual switching of the protective cover at the two stations without external drive power supply.

Abstract

The invention belongs to an auxiliary tool of a disk saw, and particularly relates to a multifunctional protective cover of the disk saw. The multifunctional protective cover of the disk saw comprises a casing; the lower end of the casing is opened; the casing is arranged in the mode of doing reciprocating motion in the vertical direction; two loose-leaf type end plates are arranged on the casing and correspond to the front end and the back end of the disk saw; the upper ends of the two end plates are hinged to the top wall of the casing, so that the two end plates can warp towards the front end and the back end of the casing correspondingly, and the two end plates and the top wall of the casing form an arch-shaped baffle plate. The protective cover provided by the invention can serve as an enclosing device to enclose the disk saw when the disk saw does not work so as to prevent the disk saw from accidentally injuring the surrounding workers; the protective cover also can serve as a baffle plate to shelter the upper space of the saw disk in the working process of the disk saw so as to prevent waste residues from splashing and provide effective protection for operators.

Description

technical field [0001] The invention belongs to auxiliary tooling for circular saws, in particular to a multifunctional protective cover for circular saws. Background technique [0002] Circular saw is a kind of commonly used cutting equipment. Its disk surface is arranged vertically. Half of the disk surface is located under the equipment workbench and connected to the transmission mechanism, and the other half of the disk surface is located above the workbench for cutting objects to be processed. There are sharp barbed or blade-like serrations around the disc surface of the circular saw. If it is not protected at ordinary times, it is easy to cause harm to the human body. In addition, the circular saw will splash a lot of waste during the working process. If it is not protected, it will cause the waste to splash everywhere. On the one hand, it is difficult to clean, and on the other hand, the waste in the air will cause damage to the human respiratory tract. Contents of ...
