AI Technical Summary
In the prior art, the high-precision cutting tool stroke control equipment required for the cutting of lens outer diameter is expensive and difficult to meet the needs of small and micro enterprises. There is a lack of a manual control solution with a simple structure and low cost.
A cutting stroke control mechanism including a fixed frame plate, an active rotating disc, a worm gear, a worm and a top stop rod is designed. By manually rotating the active rotating disc, the worm gear and worm are driven, and the maximum stroke control of the cutting tool is achieved using the worm support sleeve.
It realizes manual and precise control of the maximum stroke of the cutting tool, reducing costs, and meeting the precise needs of lens cutting processing.

Abstract
Description
Technical Field
[0001] The utility model relates to a cutting stroke control mechanism. Background Art
[0002] In the lens outer diameter cutting process, a cutting knife is required to cut the outer diameter of the lens in the past. The cutting knife stroke for the cutting depth of the lens is usually controlled by high-precision control machinery and equipment, but the cost of high-precision control machinery and equipment is high, and it is difficult for general small and micro enterprises to purchase. Therefore, it is necessary to design a cutting stroke control mechanism with simple structure and low cost that uses manual control to control the maximum cutting stroke of the cutting knife. Utility Model Content
[0003] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a cutting stroke control mechanism which has a simple structure and low cost and can manually and accurately control the maximum cutting stroke of a cutting knife.
[0004] The utility model comprises a fixed frame disc, an active rotating disc, a worm wheel, a worm and a top stop rod, wherein the active rotating disc is adapted to be horizontally rotated and inserted on the right side of the fixed frame disc, the worm wheel is adapted to be fixedly rotated and connected to the end of the active rotating disc and is adapted to be rotated and placed on the left side of the fixed frame disc, the worm is adapted to be horizontally movable and placed on the left side of the fixed frame disc, the worm is adapted to be meshed with the worm wheel, and the top stop rod is horizontally adapted to be fixedly connected to the end of the worm.
[0005] A worm support sleeve is horizontally fixed on the left side of the fixed frame plate, the worm is rotatably inserted in the worm support sleeve, the outer wall of the worm support sleeve is provided with an engagement groove, and the worm wheel is engaged with the worm transmission at the engagement groove.
[0006] Beneficial effect: In the utility model, by manually rotating the active rotating disk, the worm wheel can be driven to rotate, thereby driving the worm to move forward and backward horizontally in the worm support sleeve. The active rotating disk is rotated and the stop rod is stopped after reaching a preset position. At this time, the distance between the external cutting machine and the end of the stop rod is the maximum cutting stroke of the external cutting machine, thereby controlling the maximum cutting amount of the lens. BRIEF DESCRIPTION OF THE DRAWINGS
[0007] Figure 1 It is a structural schematic diagram of the utility model. DETAILED DESCRIPTION
[0008] like Figure 1As shown, the utility model includes a fixed frame disc 1, an active rotating disc 2, a worm wheel 3, a worm 4 and a top stop rod 5. The active rotating disc 2 is adapted to be horizontally rotated and inserted on the right side of the fixed frame disc 1, the worm wheel 3 is adapted to be fixedly rotated and connected to the end of the active rotating disc 2 and is adapted to be rotated and placed on the left side of the fixed frame disc 1, the worm 4 is adapted to be horizontally movable and placed on the left side of the fixed frame disc 1, the worm 4 is adapted to be meshed with the worm wheel 3, and the top stop rod 5 is horizontally adapted to be fixedly connected to the end of the worm 4.
[0009] A worm support sleeve 11 is horizontally fixed on the left side of the fixed frame plate 1. The worm 4 is rotatably inserted in the worm support sleeve 11. The outer wall of the worm support sleeve 11 is provided with an engagement groove 111. The worm wheel 3 is in driving engagement with the worm 4 at the engagement groove 111. The outer wall of the stop rod 5 is engraved with a calculated length mark to specifically indicate the current extension length.
[0010] The fixed frame plate 1 is fixedly set on the fixed plate of the external lens fixture table, and the active rotating plate 2 rotates horizontally and penetrates the fixed plate of the external lens fixture table. The active rotating plate 2 is rotated, so that the worm wheel 3 drives the worm 4, and then drives the worm 4 to move forward and backward in the worm support sleeve 11, and finally drives the top stop rod 5 to move forward and backward relative to the external cutting machine. After stopping the forward and backward movement, the distance between the top stop rod 5 and the external cutting machine position is the set cutting machine stroke, thereby controlling the cutting depth of the cutting machine on the lens.
[0011] The utility model is suitable for the field of lens cutting and processing.
