Description
Technical field
The utility model relates to a kind of self-feeding locating device, specifically is a kind of impact testing machine self-feeding locating device.
Background technology
Impulse detection during at present mechanics detects belongs to the main test project, in the impulse detection test method, about the structure of self-feeding, location several kinds of forms is arranged: mechanical type, pneumatic type.
The problem and the shortcoming of the device that uses at present are:
Mechanical type: machined part is of a great variety, and various parts quality of fits, morpheme error requirements are higher, and the outsourcing piece kind is numerous and diverse, and matching requirements are higher.More because of the interlock link, be prone to because of processing, the improper locked or operation problem such as not smooth of parts that occurs of assembling.
Pneumatic type: used location, the pay-off in existing this area is three air cylinder structures.I.e. location, feeding, clamping.Though reduce many workpieces and outsourcing piece, because be three cylinder movings, need each action proceed step by step, institute's elapsed time prolongs, inefficiency.
Summary of the invention
The utility model provides a kind of impact testing machine self-feeding locating device that utilizes pneumatic type to combine the mechanical type interlock for the basis in order to remedy the deficiency of prior art.
The utility model comprises stock support and positioning cylinder support; Its special character is: an end of described stock support is provided with preceding bearing, and preceding bearing is provided with jaw, and stock support is provided with feeding cylinder; One end of described positioning cylinder support is provided with rear support; Rear support is provided with jaw and positioning seat, and the positioning cylinder support is provided with positioning cylinder, and positioning seat is connected with the cylinder rod contact of positioning cylinder.Sample is placed on the preceding bearing, sample is passed forward, when front end gets into vice jaw surface 2 ~ 3mm through the effect of feeding cylinder; Feed mechanism PLC Programmable Logic Controller sends signal, the action of cylinder electromagnet, detent mechanism action immediately; The cylinder rod of detent mechanism is to the working position; Sample is pressed in the detent mechanism side, is close to the detent mechanism locating surface until the sample front end face, accomplishes sample location work.
The corresponding setting of bearing before described with rear support.So just can accomplish the feeding and the location work of sample easily.
Bearing is provided with the guide holder sheet before described.The setting of guide holder sheet just can guarantee the direction of motion of sample on preceding bearing.
The position corresponding with preceding jaw is provided with stationary spring on the described preceding bearing.Because the effect of stationary spring makes sample can be close to preceding jaw side and moves forward, the acting in conjunction of guide holder sheet and stationary spring is when making sample from sample box, be pushed out to striking point, is unlikely to the crooked sample that guarantees simultaneously and can drop because of gravity effect.
Described rear support is provided with the revoliving arm bearing, and the revoliving arm bearing is provided with revoliving arm, and revoliving arm is connected with eccentric wheel is tangent, is provided with spring and location nail with the corresponding end of back jaw on the revoliving arm.Eccentric wheel can reduce the inertia impact of detent mechanism to sample, therefore can improve the accuracy of sample location.The revoliving arm rotation drives the spring motion that front end is provided with, and telescopic spring is located nail certain function power, and the location nail just can compress the side of sample in jaw position, back, guarantees and accomplish the lateral register of sample.
All be provided with solenoid valve on described feeding cylinder and the positioning cylinder.Through the running of solenoid valve, the motion of control cylinder.
The beneficial effect of the impact testing machine self-feeding locating device of the utility model: self-feeding, location, accurate positioning, high efficiency, simple to operate, easy to use, device structure is simple, and applicable situation is wide.
