Description

Technical Field

[0001] The utility model relates to a limit switch structure of a processing machine. Background Art

[0002] Generally, various common electric processing machines use electric energy as the power drive, allowing users to easily achieve the desired processing purposes, such as: electric drilling machines for drilling, electric screwdrivers for screwing and loosening, electric waxing machines for vehicle waxing, electric fruit and vegetable processors for juicing fruits and vegetables, etc., which bring great convenience to users in operation and use, making them widely purchased and used by all walks of life.

[0003] Among them, as for the commonly used processing tools for processing and drilling holes in workpieces, a working platform is mainly provided on a base for placing the workpiece, and a processing tool is provided above the working platform. The processing tool is driven to rotate by a power source, and a control unit is provided to control the rise and fall of the processing tool; during operation, the workpiece is placed on the working platform, the power source is started to drive the processing tool to rotate, and then the processing tool is controlled to descend by the control unit, and the processing tool can be used to process the workpiece.

[0004] However, although the above-mentioned processing machine can utilize the rotating processing tool to achieve the expected effect of processing the workpiece, it is also found in its actual operation and use that when the structure is started, the power source will directly drive the processing tool to rotate, so that the processing tool is in a state of continuous rotation when it is started, which not only causes a waste of electric energy resources, but also the rotating processing tool is easy to be accidentally touched by the operator during the process of placing and removing the workpiece, resulting in various dangerous accidents and causing concerns about work safety, so that there is still room for improvement in its overall structural design.

[0005] Therefore, in view of this, the inventor, based on his rich design, development and actual production experience in the related industry for many years, further researched and improved the existing technical means to provide a processing machine limit switch structure in order to achieve better practical value. Utility Model Content

[0006] The main purpose of the utility model is to provide a limit switch structure for a processing machine, which can drive the processing tool to rotate only when the operator controls the feed of the processing tool, so that it can not only save power consumption in use, but also be safer in use. When the operator places or takes out the workpiece, it can prevent the operator from being accidentally injured by the rotating processing tool, avoid the occurrence of work safety problems, and increase the practical efficacy characteristics in its overall implementation and use.

[0007] The main purpose and function of the limit switch structure of the processing machine of the utility model are achieved by the following specific technical means:

[0008] The main structure includes a limited switch structure; wherein:

[0009] The limit switch structure corresponds to a control unit of a processing machine that controls the advance and retract of a processing tool and is provided with a rotating member. The rotating member rotates synchronously with the control unit controlling the advance and retract of the processing tool. A start section and a stop section are respectively formed on the outer edge of the rotating member. A touch switch is provided above the rotating member and is electrically connected to a power source that drives the processing tool to rotate. A touch portion is formed below the touch switch and corresponds to the rotating member. Under normal circumstances, the touch portion corresponds to the stop section. The touch switch controls the power source to be cut off. When the rotating member rotates to the point where the start section corresponds to the touch portion, the touch switch controls the power supply to the power source, and the power source drives the processing tool to rotate.

[0010] In the preferred embodiment of the limit switch structure of the processing machine of the utility model, the rotating member is tightly combined and fixed with the control unit by means of a screw fixing element.

[0011] In the preferred embodiment of the limit switch structure of the processing machine of the utility model, the rotating member and the touch switch are both arranged on a fixed seat.

[0012] The preferred embodiment of the limit switch structure of the processing machine of the utility model is that the fixed seat is provided with an arc guide groove, and the rotating member is provided with a limit member corresponding to the arc guide groove. During the rotation of the rotating member, the limit member is driven to move in the arc guide groove and limit the rotation angle of the rotating member.

[0013] Compared with the existing structure, the utility model mainly has the following advantages:

[0014] 1. The utility model can drive the machining tool to rotate only when the operator controls the machining tool to feed, so that the utility model can save more power consumption in use.
