Description

Technical Field

[0001] The utility model relates to the technical field of safety protection of a workpiece loading area of ​​a machine tool, in particular to a safety pedal for a machine tool loading area. Background Art

[0002] With the rapid development of automobile industry technology, traditional automobile parts have evolved from stamping, welding, and riveting to one-piece die-casting. The number of automobile parts and the overall process complexity will decrease rapidly, but the technical requirements for metal cutting will evolve towards high efficiency and high precision. Especially with the leapfrog development of die-casting molding equipment and molding processes, the size and weight of one-piece die-cast parts will develop towards large-scale. In this development process, metal cutting machine tools will also develop towards large-scale development. When traditional small parts are produced and processed, a single person can complete the entire production operation process, which is convenient and fast. As parts become larger, production operations will evolve from traditional single-person operations to two or more people's operations. When two or more people operate the same machine, many challenges and requirements will be raised for the coordination and safety interlocking of operations.

[0003] The safe operation of the machine tool loading area in the prior art is more inclined to the standardized management of the operating process. However, the existing machine tool loading area lacks personnel sensing equipment, and the staff may violate the operating procedures and operate illegally, posing a safety hazard.

[0004] Therefore, how to provide a safety pedal for a machine tool loading area to solve the problems existing in the prior art is of great significance to its application. Utility Model Content

[0005] In view of this, the purpose of the present application is to provide a safety pedal for a machine tool loading area to solve the problem that the existing machine tool loading area lacks personnel sensing equipment, and the staff may operate illegally without following the operating procedures, posing a safety hazard.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A safety pedal for a machine tool loading area comprises a main support frame, a floating support frame, a guide bull's eye, an upper travel limit plate, a travel sensor and an elastic support seat;

[0008] The floating support frame is placed inside the main support frame, the guide bull's eye is installed on the side of the inner wall of the main support frame, the floating support frame is slidably connected with the main support frame through the guide bull's eye, the upper travel limit plate is installed on the side of the top end of the main support frame, and the upper travel limit plate is used to limit the height of the floating support frame;

[0009] The elastic support base is installed at the bottom end of the floating support frame. The floating support frame is elastically connected to the main support frame through the elastic support base. The stroke sensor is installed on both sides of the main support frame.

[0010] Preferably, the elastic support base includes a plug, a housing, a resilient pin and a spring. The plug and the housing are connected by threads. The resilient pin is elastically connected to the housing through the spring. The top end of the plug is fixedly connected to the floating support frame by screws.

[0011] Preferably, the housing gradually tapers from top to bottom. The bottom end of the housing is a through hole, and the bottom end of the resilient pin protrudes from the through hole.

[0012] Preferably, the number of the upper stroke limit plates is four. The four upper stroke limit plates are respectively installed at the corners of the main support frame. The number of the guiding bull's eyes is six. Two guiding bull's eyes are respectively arranged on the front and rear sides of the main support frame, and one guiding bull's eye is arranged on each of the left and right sides. The number of the elastic support bases is six. Four of the elastic support bases are respectively installed at the four corners of the floating support frame, and the other two elastic support bases are respectively installed at the middle parts of the front and rear sides of the floating support frame.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] The utility model detects personnel by setting a floating support frame and a stroke sensor. When the floating support frame is in a state of no person or no load, under the action of the elastic support base, it is in the uppermost state. At this time, the stroke sensor cannot detect the floating support frame. When there is a person or a load on the floating support frame, under the action of the load, the floating support frame moves downward to the lower limit. At this time, the stroke sensor senses the floating support frame, so as to achieve personnel perception, standardize personnel operation and improve the safety during use.
