Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, in actual manufacturing, the three-dimensional spatial dimensions of length, width, and depth should be included.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0021] Figures 1-3 The diagram shown is a complete structural schematic of an adapter cutting device according to this utility model. Please refer to [link / reference]. Figures 1-3 An adapter cutting device according to this embodiment includes a worktable 100, a cutting slit 110 at the top front end of the worktable 100, and a cutting machine 120 that drives a cutting disc to reciprocate along the length of the cutting slit 110 via a driving device. A slide groove 130 is provided on one side of the worktable 100 along its length, with the front end of the slide groove 130 adjacent to the cutting slit 110. A movable stage 200 is slidably mounted inside the slide groove 130. An electric push rod 600 for pushing the movable stage 200 to move back and forth is provided at the rear end of the inner side of the slide groove 130. A processing turntable 300 is horizontally rotatably mounted on the top of the movable stage 200 near the front end. A positioning and clamping assembly 400 for fixing a PCB board is provided on the top of the processing turntable 300 near the rear end. A braking assembly 500 for rotating and braking the processing turntable 300 is also provided on one side of the processing turntable 300.

[0022] In this embodiment, the positioning and clamping assembly 400 includes a positioning baffle 410 horizontally fixed to the top of the machining turntable 300, a mounting bracket 420 fixed to the upper end of the positioning baffle 410, a cylinder 440 vertically mounted to the top of the mounting bracket 420, and a pressure plate 430 located below the straight section of the mounting bracket 420 and fixedly connected to the output shaft end of the cylinder 440; wherein, the pressure plate 430 is located on the front end side of the positioning baffle 410 facing the machining turntable 300, and the bottom of the pressure plate 430 also has a rubber pad. Understandably, before cutting, one edge of the PCB board is first placed against the positioning baffle 410, so that the edge of the PCB board to be cut is located at the opposite end of the positioning baffle 410. Then, the cylinder 440 is activated by the control switch. Under the action of the cylinder 440, the baffle 410 moves downward and presses the PCB board firmly onto the processing turntable 300. This is more efficient than the traditional manual screwing and fixing, and is suitable for mass production. It should be noted that the front end of the positioning baffle 410 plays a parallel supporting role, and the part of the PCB board to be cut extends to the front end of the positioning baffle 410.

[0023] In this embodiment, the upper part of the movable stage 200 near the front end has a circular mounting groove 220. A shaft disc 320 is coaxially fixed to the bottom of the machining turntable 300 and inserted into the mounting groove 220. A bearing ring 230 is provided at the connection between the mounting groove 220 and the shaft disc 320. The braking assembly 500 includes a threaded cylinder 510 vertically fixed to the machining turntable 300 and a screw 520 threadedly connected to the inside of the threaded cylinder 510 and with its bottom abutting against the top of the movable stage 200. A protractor scale 210 is also provided on the top of the movable stage 200 near the rear end, and a pointer head 310 that mates with the protractor scale 210 is also provided at the rear edge of the machining turntable 300. It can be understood that the oblique angle of the PCB board corresponds to the point indicated by the pointer head 310 on the protractor scale 210. A controller 700 is also provided on one side of the upper end of the worktable 100. The controller 700 is the main control unit of this cutting device. Operators can use the controller 700 to operate and set the various operating units on the device. Specifically, by placing the PCB board flat on the processing turntable 300 and using the positioning clamping assembly 400 to press and stabilize the PCB board, the operator can then rotate the processing turntable 300 according to the value indicated by the pointer 310 pointing to the angle scale line 210 until the indicated value reaches the corresponding bevel angle of the PCB board. After completion, the screw 520 is tightened to stabilize the processing turntable 300 on the moving table 200. Then, the electric push rod 600 is activated, pushing the moving table 200, processing turntable 300, and PCB board forward, so that the line to be cut on the PCB board coincides with the cutting seam 110. Subsequently, the cutting machine 120 and cutter head, activated from one side, will move horizontally across the PCB board and perform an angled cut, effectively solving the drawback of existing technologies that can only perform bevel cuts on PCB boards of specific sizes, thus improving cutting convenience and application range.

[0024] In summary, the adapter cutting device of this embodiment, when in use, involves placing the PCB board flat on the processing turntable 300 and using the positioning clamping assembly 400 to press and stabilize the PCB board. Then, the operator can rotate the processing turntable 300 according to the value pointed to by the pointer 310 on the protractor scale 210 until the indicated value reaches the corresponding bevel cutting angle of the PCB board. After completion, the screw 520 is tightened to stabilize the processing turntable 300 on the moving table 200. Then, the electric push rod 600 is activated to push the moving table 200, the processing turntable 300 and the PCB board forward, so that the line to be cut on the PCB board coincides with the cutting seam 110. Subsequently, the cutting machine 120 and the cutter head activated on one side will move horizontally across the PCB board and perform a bevel cutting on it, effectively solving the drawback of the prior art that can only bevel cutting of PCB boards of specific sizes.

[0025] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
