Description

Technical Field

[0001] The present invention relates to the technical field of cutting machines, and more particularly to a pedal-type cutting machine. Background Art

[0002] Profile cutting machine is suitable for sawing various special-shaped metal aluminum, aluminum alloy, copper, copper alloy, non-metallic plastic and carbon fiber materials, especially suitable for sawing aluminum doors and windows, photo frames, plastic steel, bakelite, aluminum extrusion, paper tube and profiles.

[0003] However, the existing cutting machines require both hands to operate during the process of cutting profiles, which not only makes the operation cumbersome and reduces work efficiency, but also needs to be improved in safety. Especially for special groups such as one-armed or armless disabled people, it undoubtedly increases their operating difficulty and has low applicability.

[0004] Therefore, providing a pedal-operated cutting machine that frees both hands is a problem that those skilled in the art need to solve urgently. Summary of the invention

[0005] In view of this, the present invention provides a pedal-type cutting machine that does not require both hands to operate and is also suitable for special groups such as disabled people with one arm or no arms.

[0006] In order to achieve the above object, the present invention adopts the following technical solution:

[0007] A pedal-type cutting machine, comprising:

[0008] The cutting machine body comprises a base, a mounting frame, a connecting plate and a tension spring; the base is placed and fixed on a workbench; the rear end of the mounting frame is hinged to the base; a handle and a saw blade driven by a servo motor are fixed on the mounting frame; a first self-reset switch electrically connected to the servo motor is installed on the handle; the connecting plate is fixed to the rear end of the mounting frame and is tilted upward; one end of the tension spring is installed on the rear end of the base, and the other end of the tension spring is installed on the connecting plate;

[0009] A foot pedal, wherein the top extension end of the foot pedal is connected to the bottom of the connecting plate through a connecting rod mechanism;

[0010] A foot switch driving mechanism, the foot switch driving mechanism includes a support plate, a support frame, a bearing plate and a foot tube; the support plate is vertically fixed to the side of the top of the foot pedal, and a longitudinal limit hole is opened on the support plate; a second self-resetting switch electrically connected to the power supply is installed at the bottom of the longitudinal limit hole, and the second self-resetting switch is electrically connected to the servo motor; the support frame is fixed to the outer side surface of the support plate; one end of the bearing plate is hinged on the support frame, and the other end of the bearing plate extends to the longitudinal limit hole and is placed on the top of the second self-resetting switch; the foot tube located above the foot pedal passes through the longitudinal limit hole and is fixed on the bearing plate.

[0011] By adopting the above scheme, the beneficial effects of the present invention are:

[0012] The foot pedal is manually stepped on and moved downward. Under the transmission action of the connecting rod mechanism, the connecting plate drives the mounting frame to move downward, that is, the mounting frame rotates downward on the base. At the same time, the foot tube above the foot pedal is manually stepped on and moved downward, and the foot tube and the bearing plate move downward. The second self-resetting switch is pressed to start the servo motor to drive the saw blade to cut the workpiece on the workbench. When the foot is lifted, the foot pedal is reset. Under the action of the tension spring, the mounting frame is lifted again and the foot tube is reset. The second self-resetting switch is reset, the servo motor is turned off, and the saw blade stops rotating. The entire operation process does not require both hands, and the operation is simple and convenient, which improves work efficiency and increases safety to prevent the saw blade from cutting the arm.

[0013] Furthermore, the foot pedal includes a bottom plate, a middle plate and a top plate; the bottom plate, the middle plate and the top plate are hinged together in sequence; the support plate is vertically fixed to the side of the top plate; and the foot pedal tube is located above the top plate.

[0014] Furthermore, the connecting rod mechanism includes a first connecting rod and a second connecting rod; one end of the first connecting rod is hinged to the extended end of the top plate; the other end of the first connecting rod is hinged to one end of the second connecting rod, and the other end of the second connecting rod is hinged to the bottom of the connecting plate.

[0015] The beneficial effect of adopting the above-mentioned further technical solution is that when the top plate is manually stepped on, the top plate and the middle plate rotate and move downward, the top plate pulls the first connecting rod, the first connecting rod then pulls the second connecting rod, and the second connecting rod pulls the mounting frame through the connecting plate, thereby realizing that the mounting frame drives the saw blade to move downward.

[0016] Furthermore, it also includes a positioning plate, which is vertically fixed on the top of the base near the tail end, and the positioning plate has a longitudinal through hole corresponding to the saw blade.

[0017] The beneficial effect of adopting the above further technical solution is that the workpiece on the workbench can be positioned to improve the cutting accuracy. BRIEF DESCRIPTION OF THE DRAWINGS
