Description

Technical Field

[0001] This invention belongs to the technical field of safety protection devices for machine tools, and particularly relates to a safety protection device for a bench drill. Background Technology

[0002] A drilling machine is a machine tool that primarily uses a drill bit to machine holes in a workpiece. Typically, the rotation of the drill bit is the main motion, while the axial movement of the drill bit is the feed motion. Drilling machines have a simple structure and relatively low machining accuracy. They can drill through holes and blind holes. By changing special cutting tools, they can also perform reaming, countersinking, boring, or tapping operations. A key characteristic of drilling machines is that the workpiece remains stationary while the cutting tool rotates.

[0003] A bench drill, or bench drill for short, is a small hole-making machine tool that is compact, easy to operate, and usually installed on a special workbench. During the drilling process, the tool rotates at high speed, and the operator's face is very close to the machine tool, which causes the following problems: (1) Iron chips fly everywhere under the action of centrifugal force; or due to unsuitable cutting force, the chips cannot be broken naturally, and long iron chips stick to the tool and rotate at high speed with the tool, which poses a potential danger to the operator; (2) If the right hand is used improperly during the drilling process, the cutting edge may break off and fly out, causing injury to the operator; (3) If work clothes and hats are not worn in accordance with the operating procedures, long hair braids or clothing accessories may easily get caught in the spindle, causing personal injury. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the present invention provides a safety protection device for a bench drill, which is easy to adjust. The clamping plates on both sides of the support plate can fix the device to the two outer side walls of the upper part of the drill base or to the outer side wall of the drill rotary table. It can be adjusted according to the usage requirements, and the protection height of the baffle can be adjusted. The angle of the flipping plate can be adjusted by the flipping rod.

[0005] The technical solution adopted in this invention is as follows: A safety protection device for a bench drill includes a support plate, a connecting plate, a clamping plate, and an adjustable protective component. The connecting plate is arranged in an X-shape, and the support plates are located on both sides of the connecting plate in a symmetrical arrangement. The clamping plates are located on both sides of the upper part of the support plate in a symmetrical arrangement. The adjustable protective component is located on one side of the connecting plate and includes a rotating shaft, a rotating plate, a sliding plate, a baffle, a connecting rod, a flipping plate, a tilting rod, and a limiting block. The rotating shaft is located at the center of the bottom of the connecting plate, and the upper part of one side of the rotating shaft is located at the bottom of the connecting plate. The sliding plate is located on the outer wall of the rotating plate away from the rotating shaft. A sliding groove is provided in the middle of the sliding plate. The baffle is slidably located in the sliding groove. A groove is provided in the middle of the baffle. The connecting rod is rotatably located in the groove opposite to the two inner side walls. The flipping rod is located in the middle of the side wall of the connecting rod. The flipping plate is rotatably located on the flipping rod. The limiting block is located at the end of the flipping rod away from the connecting rod. The flipping plate is located in the groove.

[0006] Furthermore, a fixing bolt is provided in the middle of the outer wall of the sliding plate to fix the baffle. When the baffle slides up and down for adjustment, the fixing bolt is rotated to clamp and fix the baffle.

[0007] Furthermore, the clamping plate is provided with rubber pads on the upper part of its inner sidewall, and the rubber pads are arranged symmetrically in pairs to increase the friction between the clamping plate and the drill press base or rotary table.

[0008] Furthermore, a positioning stud is connected to the center of the clamping plate. The positioning stud is threaded to the clamping plate. The positioning studs are arranged symmetrically in pairs to fix the device. Rotating the positioning studs will fix the clamping plate to the drilling machine base or the side wall of the rotary table.

[0009] Furthermore, the damping connection between the flipping plate and the flipping rod allows for adjustment of the protective angle after the flipping plate is flipped out, providing protection for the face and eyes according to the different heights of the operators.

[0010] Furthermore, the damping connection between the rotating shaft and the rotating plate allows the adjustable protective assembly to rotate, facilitating positioning and adjustment.

[0011] With the above structure, the beneficial effects of the present invention are as follows: The safety protection device for bench drill proposed in this invention has a simple structure, is easy to use and easy to adjust. The clamping plates on both sides of the support plate can fix the device to the two outer side walls of the upper part of the base of the drill or to the outer side wall of the rotary table of the drill. It can be adjusted according to the usage requirements. At the same time, the sliding plate is adjusted and fixed in the sliding groove to adjust the protection height. The flipping plate rotates around the connecting rod as the center, and the angle can also be adjusted by the flipping rod. Attached Figure Description
