Background technology
In the machining, drilling processing is common a kind of processing mode.In the boring procedure, people clamp part with conventional universal fixturings such as hand vice, flat-nose pliers, V shape iron and pressing plates usually; Also have and adopt hand held method to carry out part drilling processing parts.But for the part of the irregular contour of complexity, the bad clamping of conventional anchor clamps, and clamping process is numerous and diverse, and chucking power is excessive too small, all can cause part deformation, borehole accuracy not high, and production efficiency is low; Especially adopt the method for hand-held processing parts to exist potential safety hazard more, be unfavorable for that operating personnel work.
The utility model content
The technical problems to be solved in the utility model is that the conventional anchor clamps that exist when solving above-mentioned drilling processing profile irregular part can not clamp, driller's precision is not high, production efficiency is low, problem such as potential safety hazard is arranged, and a kind of boring grab of being convenient to load and unload and clamp the profile irregular part is provided.
For the technical problem of institute's art above solving, the utility model by the following technical solutions:
A kind of boring grab comprises base plate and is fixed on the column of base plate left end and is fixed on the backing plate of base plate right-hand member that the bushing plate that the column upper end is fixedly connected studs with drill bushing on the bushing plate; Be provided with locating shaft in the middle of the column; Be fixedly connected with saddle on the backing plate, saddle be provided with column on the coaxial propelling clamp mechanism of locating shaft, advance clamp mechanism and the handle and connecting rod mechanism that is fixed on the backing plate to flexibly connect.
In order better to clamp the part to be processed of irregular contour, advance clamp mechanism to comprise pushing ram, pushing ram passes saddle with a gap, and the connecting rod of pushing ram right-hand member and handle and connecting rod mechanism flexibly connects; In order to treat processing parts protection, the pushing ram left end is fixedly connected with fixed block and rubber blanket.In order in use to change rubber blanket, fixed block and rubber blanket are installed in the pushing ram left end removably.
Control the advance and retreat of pushing ram for convenience, handle and connecting rod mechanism comprise the connecting rod that flexibly connects with pushing ram, with the connecting rod rest that connecting rod flexibly connects, with the frame that connecting rod rest flexibly connects, frame is fixed on the backing plate; Handle and connecting rod rest flexibly connect.
For location part to be processed is installed, a locating shaft is set on column, the external diameter of the big end of locating shaft and part locating hole to be processed are suitable.
The beneficial effects of the utility model: the locating shaft on the column can be part to be processed location, propulsive mechanism is treated processing parts and is clamped, boring on the bushing plate can pilot bit be found bore position accurately, so the parts fixation of processing irregular contour is reliable, precision is high, production safety, handle bindiny mechanism can control the advance and retreat of propulsive mechanism, and is easy to operate, production efficiency height, but wide popularization and application.
