Background technology
Gear-box is the most common a kind of machine power connecting gear that arrives, and in the automatic control technology field, gear-box usually cooperates motor production to control driver automatically.In order to protect the motor good working environment, it is the most frequently used a kind of means that motor installs protective cover additional.Automatically gear-box and the motor shield mount pad in the control driver is typically designed to integral structure, and gear-box is usually produced with the mode of die casting, so motor shield mount pad on the corresponding teeth roller box, need three of other drillings to be mutually the protective cover installing hole of 120 ° of angles, this installing hole is necessary by protective cover is installed on the one hand, the aspect can make protective cover install firmly in addition, reduces the drive operation noise.Gear-box protective cover installing hole is if process with common driller, machining accuracy and work efficiency are all very low, gear-box three hole drills that our company designs and develops are cut frock, its machining accuracy height and production efficiency improve greatly, originally gear-box is to be clamped on the gear-box mounting yoke by pressing plate, and complex operation has influenced production efficiency.
Summary of the invention
The purpose of this utility model is that suitable gear-box three hole drills of design are cut frock clamp, is specially a kind of gear-box three hole drills and cuts the frock locking device.
The utility model is made of base, frame, handle, drive link, depression bar, pressure head, gear-box mounting yoke, it is characterized in that frame establishes first pivot hole and second pivot hole, the handle front portion is the wooden fork shape, handle wooden fork head is established first pivot hole, the wooden fork tail is established the 3rd pivot hole, drive link is established the 3rd pivot hole and the 4th pivot hole, the depression bar front end is the wooden fork shape, depression bar wooden fork head is established second pivot hole, the wooden fork tail is established the 4th pivot hole, and frame, handle, drive link, depression bar assemble connection in twos by first pivot to the, four pivots; Pressure head is established screw mandrel, and screw mandrel is worn the pressure head mount pad of joining the depression bar rear end, and is fastening with locking nut.
Described drive link extends before the 4th pivot hole establishes prominent tooth.
Described pressure head mount pad is runway shape slotted eye.
Described pressure head material is nylon plastic(s).
The utility model adopts four-bar linkage structure, locked position, and namely the dead point is the wooden fork oral area position of the prominent tooth deduction of drive link depression bar wooden fork head.Concrete operations are: gear-box is seated in the gear-box placement seat, cocked handle, handle is rotated counterclockwise around first pivot, driving drive link by the 3rd pivot on the handle is rotated counterclockwise, drive link drives depression bar by the 4th pivot and is rotated counterclockwise around second pivot, drive pressure head and compress gear-box in the gear-box placement seat, the prominent tooth deduction of drive link front end is in the wooden fork mouth position of depression bar wooden fork head, and gear-box is locked.Machine the back as long as open handle clockwise, just be easy to realize the gear-box replacing.Pressure head establishes screw mandrel and the pressure head mount pad adopts runway shape slotted eye, makes the upper and lower and forward and backward position of pressure head easy to adjust.
The utility model beneficial effect is: scientific and reasonable for structure, simple to operation, mate gear case three hole drills are cut frock, and production efficiency further improves.
