Summary of the invention
Technical problem to be solved by this invention is: a kind of mechanical hand device for automatically feeding sample of testing machine is provided; Utilize about the guide rod cylinder, move horizontally after the rotation, finger cylinder clamping sample, common cylinder moves horizontally, and rotary cylinder drives guide rod cylinder, the finger cylinder revolves and turn 90 degrees; It is vertical to reach sample, and guide rod cylinder moves horizontally, and it is moved to the testing machine desired location.Eliminate manual operations and brought test error.
The objective of the invention is to be achieved through the following technical solutions:
A kind of mechanical hand device for automatically feeding sample of testing machine is characterized in that: it comprises line slideway auxiliary and a common cylinder and a guide rod cylinder A perpendicular to the frame setting who is fixedly arranged on the frame;
Wherein set firmly a rotary cylinder by slide block on the line slideway auxiliary; The piston-rod lower end of described guide rod cylinder A sets firmly a finger cylinder C; Rotary cylinder is affixed by a connecting axle and guide rod cylinder A; Common cylinder is located at a side of frame, by the horizontal piston rod that stretches out with rotary cylinder, guide rod cylinder A and finger cylinder C are being set and can be connected along the slide block that line slideway auxiliary slides.
The anglec of rotation of the axle on the described rotary cylinder is 90 degree, and drives guide rod cylinder A and finger cylinder C synchronously and revolve in the lump and turn 90 degrees.
By above-mentioned public technology scheme as seen, the present invention is simple in structure, easy to use, utilizes finger cylinder clamping sample, and common cylinder and guide rod cylinder move, and rotary cylinder revolves and turn 90 degrees, and it is moved to the testing machine desired location.In addition, not only make sample keep vertically having guaranteed the test controllability, eliminated manual operations and bring test error, and effectively improved measuring accuracy.
The specific embodiment
The invention will be further described below in conjunction with the drawings and specific embodiments:
See also Fig. 1-2, this mechanical hand device for automatically feeding sample of testing machine is characterized in that: it comprises line slideway auxiliary 5 and a common cylinder 1 and a guide rod cylinder A perpendicular to the frame setting who is fixedly arranged on the frame 6; Wherein set firmly a rotary cylinder 11 by slide block on the line slideway auxiliary 5; The piston-rod lower end of described guide rod cylinder A sets firmly a finger cylinder C; Rotary cylinder 11 is affixed by a connecting axle and guide rod cylinder A; Common cylinder 1 is located at a side of frame 6, by the horizontal piston rod that stretches out 4 with rotary cylinder 11, guide rod cylinder A and finger cylinder C are being set and can be connected along the slide block that line slideway auxiliary 5 slides.
The anglec of rotation of the axle on the described rotary cylinder 11 is 90 degree, and drives guide rod cylinder A and finger cylinder C synchronously and revolve in the lump and turn 90 degrees.
The operation principle and the process of mechanical hand device for automatically feeding sample of testing machine of the present invention are as follows:
After this mechanical hand device for automatically feeding sample of testing machine connects computer instruction, see shown in the accompanying drawing 1:
1, guide rod cylinder A piston rod moves, and finger cylinder C drops to stroke;
2, finger cylinder C clamps behind the sample workpiece B and guide rod cylinder A carries in the backhaul in the lump;
3, common cylinder 1 begins action, its along level under the effect of overhanging piston rod 4, the rotary cylinder 11, guide rod cylinder A and the finger cylinder C that promote to be equipped with on slide block on the line slideway auxiliary 5 and the slide block move to the stroke end in the lump; This moment, whole automatically feeding sample tool hand was moved to the position of right part guide rod cylinder A ' among Fig. 1, finger cylinder C ';
4, under the effect of guide rod cylinder A ' piston rod, finger cylinder C ' descends, puts sample once more in B ' position, location;
5, guide rod cylinder A ' and finger cylinder C ' backhaul in the lump then;
6, sample centering under sample for testing machine automatic centring device (this device is seen the present patent application people " sample for testing machine automatic centring device " of application in addition) effect;
7, move at guide rod cylinder A ' piston rod, finger cylinder C ' drops to stroke, clamps behind the sample and guide rod cylinder A ' backhaul in the lump;
8, start turning cylinder on the rotary cylinder 11, the guide rod cylinder A ', the finger cylinder C ' that are located in the rotating shaft and sample B ' revolve are turn 90 degrees cause whole automatically feeding sample tool hand to be moved to the position of right part guide rod cylinder A among Fig. 1 ", finger cylinder C "; This moment, workpiece was in B " position;
9, start guide rod cylinder A once more ", guide rod cylinder piston rod level is stretched out cause and point cylinder C " and with by its clamping sample workpiece B " to stroke;
10, treat that the testing machine jaw clamps sample after, robot device oppositely returns by operating procedure; Above-mentioned action goes round and begins again.
It is reliable that the present invention is not only simple in structure, action links up, and realizes going up automatically sample; Keep sample vertical in addition, eliminated the error that manual operations and vision are brought, can effectively improve certainty of measurement.
