Description

Mechanical arm for drawing small dimension jig

Technical field

The utility model is related to mechanical equipment technical fields, and in particular to a kind of machinery for drawing small dimension jig Arm.

Background technology

The mechanical arm for being used to draw small dimension jig in the prior art is generally included by electrically driven telescopic arm and position Clamping jaw in described telescopic arm one end, the clamping jaw need to be replaced according to the different size of jig, however, manufacture is for capturing The clamping jaw required precision of small dimension jig is very high, once the big specification mismatch less than jig of clamping jaw will result in crawl and lose It loses, therefore, for the jig of small dimension, the production cost of the prior art is high, low production efficiency, and complicated for operation.

Invention content

In order to solve the deficiencies in the prior art, the utility model, which provides one kind, can reduce production cost, improve The mechanical arm for drawing small dimension jig of production efficiency.

According to technical solution provided by the utility model, a kind of mechanical arm for drawing small dimension jig, including push Device and suction means, the pushing meanss include cylinder, and the body of rod bottom end of cylinder is connected with connecting plate, and the end of the connecting plate is opened Equipped with first through hole, connect one end of the first spring below the connecting plate at the first through hole position, first spring it is another One end is fixed on push rod, and after the push rod passes through the first spring, top is pierced by from first through hole, and the top of push rod is equipped with Limited block；The suction means includes fixed plate, and the end of the fixed plate offers the second through-hole, second lead to the hole site The upper surface of the fixed plate at place is equipped with lower spring cup, and one end of second spring is connected on lower spring cup, and the other end passes through upper bullet Spring abutment is fixed on the top of soup stick, and after the soup stick passes through second spring, bottom end is pierced by from the second through-hole, the soup stick Bottom end is equipped with iron core；The bottom end of the push rod can be contacted with upper spring seat.

Further, the upper surface of described upper spring seat is equipped with the protrusion that material is silica gel.

Further, the bottom surface of the push rod is equipped with the contact site that material is silica gel.

The mechanical arm provided by the utility model for drawing jig is can be seen that from described above, with prior art phase Than having following advantages：Its is simple in structure, and operation is easy, can be easily by the mating reaction of pushing meanss and suction means Draw jig.

Description of the drawings

Fig. 1 is the structural schematic diagram of the utility model.

1. cylinder, 2. connecting plates, 3. first springs, 4. push rods, 5. limited blocks, 6. fixed plates, 7. lower spring cups, 8. second Spring, 9. upper spring seats, 10. soup sticks, 11. iron cores, 12. protrusions, 13. contact sites.

Specific implementation mode

To make the purpose of this utility model, technical solution and advantage be more clearly understood, below in conjunction with specific embodiment, and With reference to attached drawing, the utility model is further described.Wherein identical parts are presented with like reference characters.It needs Illustrate, word "front", "rear" used in the following description, "left", "right", "up" and "down" refer to the side in attached drawing To.The word "inner" used and "outside" refer respectively to the direction towards or away from geometric center of specific component.

As shown in Figure 1, a kind of mechanical arm for drawing small dimension jig, including pushing meanss and suction means, it is described Pushing meanss include cylinder 1, and the body of rod bottom end of cylinder 1 is connected with connecting plate 2, and the end of the connecting plate 2 offers first through hole, institute One end that the connecting plate 2 at first through hole position connects the first spring 3 below is stated, the other end of first spring 3, which is fixed on, to be pushed away On bar 4, after the push rod 4 passes through the first spring 3, top is pierced by from first through hole, and the top of push rod 4 is equipped with limited block 5； The suction means includes fixed plate 6, and the end of the fixed plate 6 offers the second through-hole, at second lead to the hole site The upper surface of fixed plate 6 is equipped with lower spring cup 7, and one end of second spring 8 is connected on lower spring cup 7, and the other end passes through upper bullet Spring abutment 9 is fixed on the top of soup stick 10, and after the soup stick 10 passes through second spring 8, bottom end is pierced by from the second through-hole, described The bottom end of soup stick 10 is equipped with iron core 11, and the iron core 11 is for drawing jig；It the bottom end of the push rod 4 can be with upper spring seat 9 Contact.

The upper surface of described upper spring seat 9 is equipped with the protrusion 12 that material is silica gel, and described raised 12 can play reduction friction Effect.

The bottom surface of the push rod 4 is equipped with the contact site 13 that material is silica gel, and the contact site 13 can play reduction friction Effect.

The course of work of the utility model is as follows：

The up and down motion of 1 body of rod of pushing meanss cylinder drives connecting plate 2 to move, to push the fortune of suction means soup stick 10 It is dynamic, so that iron core 11 draws jig.
