CNC Machining (CNC Machining) numerical control Machining refers to Machining with a numerical control Machining tool. CNC machining machines are programmed in a nc machining language, typically G-code. The numerical control machining G code language tells the machining tool of the numerical control machine tool which Cartesian position coordinate is adopted, and controls the feeding speed and the main shaft rotating speed of the tool, and functions of a tool converter, a coolant and the like. Numerical control machining has great advantages over manual machining, and parts produced by numerical control machining are very accurate and have repeatability; numerical control machining can produce parts with complex shapes which cannot be finished by manual machining. The numerical control machining technology is widely popularized, most machining workshops have numerical control machining capacity, and the most common numerical control machining modes in a typical machining workshop comprise numerical control milling, numerical control turning and numerical control EDM wire cutting (wire cut electrical discharge machining).
The processing jig is indispensable in CNC processing, and whether the processing jig design is reasonable directly influences the machining efficiency of work piece. In the operation flow of the cover plate of the existing communication processing jig, a worker puts a product → turns over the cover plate by hand → a machine station controls the conduction and pressing of an electromagnet through a code → the machine station works → an operator turns over the cover plate by hand after the processing is finished → the product is taken. The existing cover plate structure is arranged in the whole product machining process, an operator needs to manually operate the cover plate for two times, the clamping time is increased, the machining efficiency is influenced, in addition, uncertain factors can exist in the manually operated cover plate, and the risk of product appearance damage can be caused.
SUMMERY OF THE UTILITY MODEL
In order to overcome the technical defect, solve current processing tool and need the operator in processing product engineering and need secondary manual operation apron, can increase the machine tooling time, influence machining efficiency and can cause the technical problem of product appearance damage risk, the utility model aims to provide an automatic anchor clamps that open and shut in order to solve above-mentioned technical problem.
The utility model provides a technical scheme that technical problem adopted as follows:

the driving device is arranged below the workbench and connected with a rack, the rack is meshed with the gear, and the driving device is used for driving the rack to move up and down to drive the gear to rotate so as to close and open the cover plate.
Adopt above-mentioned technical scheme, drive the rack through setting up drive arrangement and remove from top to bottom and drive the gear rotation, the gear rotation interlock apron realizes the closure, compresses tightly the work piece on the workstation, and the apron is opened, loosens the work piece that compresses tightly, does not need the operator to need secondary manual operation apron to reach reduction clamping time, promote machining efficiency, simultaneously, stopped manual operation apron and caused the risk of product outward appearance damage, simple structure, the practicality is very strong.
For better solving the technical defect, the utility model discloses still have better technical scheme:
in some embodiments, one side edge of the workbench is provided with an avoiding groove, a side plate is fixedly connected to one side edge of the workbench, which is provided with the avoiding groove, and the side plate facilitates the fixation of the workbench in order to enable the rack to pass through and be meshed with the gear.
In some embodiments, the drive means is a pneumatic or hydraulic cylinder.
In some embodiments, the rack is in sliding contact with the side plate, whereby stable up and down movement of the rack can be ensured.
In some embodiments, the cover plate is detachably connected with the swing arm, so that different cover plates can be replaced to meet different product processing requirements.
In some embodiments, the avoidance groove is disposed in the middle of one side of the workbench.
In some embodiments, a bracket is arranged below the workbench, the top of the bracket is fixedly connected with the workbench, and one side of the bracket is fixedly connected with the side plate, so that the workbench can be more firmly connected with the side plate.
