Description

Stepping motor driver Technical Field The present utility model relates to a stepping motor, and more particularly, to a stepping motor driver. Background With the rapid development of the industry of step drives, the market end has higher and higher requirements on the performance of step drives, and in order to meet the limited space and different use environments, a step drive product with high integration level and diversified functions is generally pursued. The main technical drawbacks of the prior art include: 1) Most of stepping motor drivers in the market have more and more functional requirements, and the arrangement of various connectors in the product design and production process causes the PCB structure to be more and more compact, increases the difficulty of layout and wiring, and causes the PCB to be fixedly installed and more complex in the product structure design process. 2) Meanwhile, in order to meet the usability of various narrow spaces, the design of a stepping motor driver is more and more miniaturized, the assembly is complicated, the product stability is poor, and the performance of a machine faces great challenges. Disclosure of utility model It is an object of the present utility model to provide a stepper motor driver that overcomes the above-mentioned drawbacks of the prior art. The aim of the utility model can be achieved by the following technical scheme: According to one aspect of the present utility model, there is provided a stepping motor driver including a functional module, a main body casing, and a back cover, the functional module being mounted in the main body casing, the back cover being press-fixed with the main body casing, the functional module including a mounting bracket, a PCB board a, and a PCB board B, the PCB board a and the PCB board B being respectively fixed on the mounting bracket. As the preferable technical scheme, the mounting bracket is provided with a first mounting hole, the PCB A is provided with a third mounting hole, and the third mounting hole is aligned with the first mounting hole. As a preferable technical scheme, the third mounting hole and the first mounting hole are locked and fixed through a first screw. As a preferable technical scheme, the third mounting hole and the first mounting hole are both provided with two. As the preferable technical scheme, the mounting bracket is provided with a second mounting hole, the PCB B is provided with a fourth mounting hole, and the fourth mounting hole is aligned with the second mounting hole. As the preferable technical scheme, the fourth mounting hole and the second mounting hole are locked and fixed through a second screw. As a preferable technical scheme, the fourth mounting hole and the second mounting hole are respectively provided with two mounting holes. As the preferable technical scheme, the mounting bracket is a bracket formed by adopting an integrated sheet metal, a fixing groove is formed in the mounting bracket, and a protruding structural rib corresponding to the fixing groove is arranged on the rear cover. As a preferable technical scheme, the functional component is fixed with the mounting groove of the main body shell after sliding into the main body shell. As the preferable technical scheme, the rear cover is provided with a buckle, and the main body shell is provided with a buckle hole corresponding to the buckle. Compared with the prior art, the utility model has the following advantages: 1) Compared with the common stepping motor driver in the market, the utility model has the advantages of rich functions, easy assembly, easy disassembly and small volume; 2) After the PCB is fixed with the mounting bracket, the whole functional component is matched with the shell main body and is lightly slid in, finally the rear cover is pressed with force, the convex structural ribs on the rear cover are pressed tightly to tightly press the functional component, and the buckle on the rear cover is firmly locked with the shell, so that structural components are stable and do not shake; 3) The mounting bracket adopts an integral sheet metal forming process to replace a radiator which is die-cast or extruded by aluminum, and the sheet metal process has good flexibility and ductility, and can be flexibly adapted to PCB assembly during structural design. Meanwhile, the cost is saved, the weight of the product is reduced, and the driver is lighter and smaller.
