The invention is realized by the following technical scheme:
a screen cutting device comprises a base, an adjusting frame, an adjusting plate, an edge trimmer mounting frame, an edge trimmer, a dial indicator support and adjusting bolts, wherein the adjusting frame is fixedly connected to the base; the base comprises a handle and a bottom plate, and a semicircular cutter groove is formed in the bottom plate; the edge trimmer mounting frame comprises a sleeve for fixing the edge trimmer and a connecting plate fixedly connected with the adjusting plate, wherein the sleeve is provided with a fixing lug and a fixing bolt, the connecting plate is fixedly connected with the adjusting plate through a connecting piece, and the connecting plate is provided with a semicircular cutter groove; the cutter head of the edge trimmer penetrates through the semicircular cutter groove on the bottom plate and the semicircular cutter groove on the connecting plate. Preferably, the dial indicator support is connected with the adjusting frame through bolt connection or magnetic adsorption. Preferably, the adjusting frame is fixedly connected with the base through bolts. When the screen edge trimming device works, the edge of the screen is cut through the cutter head of the edge trimming machine, the accurate cutting size is determined through the reading of the adjusting bolt and the dial indicator, the edge trimming machine is fixed through the elastic fit of the bolt of the fixing lug of the installation frame of the edge trimming machine, the position of the edge trimming machine is adjusted up and down, and the cutter head is ensured to be aligned with the edge of the screen to be cut.
Compared with the prior art, the invention has the following beneficial effects:
the screen cutting need not to take nitrogen protection's machining center to process, can carry out at ordinary production and processing enterprise, solves the problem that the processing cost is high and production cycle can't be guaranteed, and reduce cost improves production efficiency, has higher machining precision simultaneously.

Detailed Description
The following detailed description of the present invention is provided in connection with the embodiments and the accompanying drawings for the purpose of helping those skilled in the art to more fully and accurately understand the concept and technical solution of the present invention and to facilitate the implementation thereof.
As shown in fig. 1 and 2, the device comprises a base 1, an adjusting frame 2, an adjusting plate 3, an edge trimmer mounting frame 4, an edge trimmer 5, a dial indicator 6, a dial indicator bracket 7 and an adjusting bolt 8. The base 1 consists of a handle 1.1 and a bottom plate 1.2 with a semicircular cutter groove, the handle 1.1 is used for holding during work, and the adjusting frame 2 is fixed on the bottom plate 1.2 of the base and fixedly connected with the bottom plate through a bolt 2-2. Two sides of the adjusting plate 3 are matched with the guide groove 2-1 of the adjusting frame 2, one end of the adjusting plate is connected with the adjusting frame 2 through the adjusting bolts 8, in order to prevent the adjusting plate from deflecting and improve the adjusting precision during adjustment, the number of the adjusting bolts 8 is three, the adjusting bolts are rotated during working, and the adjusting plate 3 linearly moves back and forth along the guide groove 2-1. The edge trimmer mounting frame 4 consists of a sleeve 4.1 for fixing the edge trimmer and a connecting plate 4.2, the connecting plate 4.2 is fixedly connected with the adjusting plate 3 through a connecting piece 4.2-1, the connecting piece comprises a bolt but is not limited to a bolt, a semicircular knife groove 4.2-2 is arranged on the connecting plate 4.2, and the connecting plate is vertically aligned with the semicircular knife groove 1.2-1 on the base 1 during mounting. An edge trimmer 5 containing a tool bit is vertically arranged on a sleeve 4.1 of an edge trimmer mounting frame 4 and is fixedly connected with a fixing lug 4.1-1 on the sleeve through a fixing bolt 4.1-2, the tool bit 5-1 of the edge trimmer vertically penetrates through a semicircular tool slot 4.2-2 on the edge trimmer mounting frame and a semicircular tool slot 1.2-1 on a base, when the edge trimmer is in operation, the fixing bolt on the fixing lug can be loosened, the edge trimmer is moved up and down until the tool bit is adjusted to a position suitable for cutting a screen, and then the fixing bolt is screwed. The dial indicator 6 is fixed on the adjusting frame 2 through bolt connection or magnetic adsorption by a dial indicator support 7, the measuring head end of the dial indicator is in contact with the edge trimmer mounting frame, and when the dial indicator works, the adjusting screw 8 is rotated to enable the adjusting plate 3 to linearly move back and forth, so that the edge trimmer mounting frame 4 connected with the adjusting plate and the edge trimmer 5 on the adjusting plate are driven to move back and forth, and meanwhile, the accurate distance of the back and forth movement is displayed through the dial indicator 6.
