Specific embodiment
It is with reference to the accompanying drawing and specific real to make those skilled in the art better understand the technical solution of the utility model
Mode is applied to elaborate to the utility model.
As depicted in figs. 1 and 2, the embodiments of the present invention disclose a kind of Pneumatic clamping pincers, Pneumatic clamping pincers packet
It includes: keeping body 10, caliper 20, spring 30, pressure-sensitive piece 50, piston 40 and mandril 41.Keeping body 10 is in certain thickness plate,
The rear end of self-sustaining body 10 offers air flue 11 into keeping body 10, which is located at one end of keeping body 10 to two side directions
Extend to form two branches 12, the two sides of self-sustaining body 10 inwardly open up that there are two 40 chamber 13 of piston, two branches 12 respectively
It is respectively communicated to two pistons, 40 chamber 13；Caliper 20 includes two, and two calipers 20 are opposite to be articulated in keeping body 10, and pivot
The two sides that position is located at the front end of keeping body 10 are connect, so that the head of caliper 20 is located at the front of keeping body 10, and caliper 20
40 chamber 13 of piston of tail portion and the side of keeping body 10 is opposite.Two pistons 40 are located in two pistons, 40 chamber 13, piston
40 sides opposite with caliper 20 are provided with mandril 41, and the mandril 41 with caliper 20 for abutting.Spring 30 is set to two pincers
Between body 20, specifically, which is set between two calipers 20 in the front of keeping body 10, the spring 30 setting
At compressive state, so that (or at releasing orientation) is opened on the head of driving caliper 20 in 20 non-stress of caliper.This to clamp
Body 20 and the opposite position of mandril 41 are contacted with mandril 41.One of head on the head of two calipers 20 is set for pressure-sensitive piece 50
The upside on another head is arranged in the inside in portion, infrared inductor 60.Infrared inductor 60 for detect 20 head of caliper it
Between with the presence or absence of to gripped object, and pressure-sensitive piece 50 for detecting chucking power of the head to gripped object of two calipers 20.Position
It is connected in the end of the air flue 11 of 10 rear end of keeping body with the external tracheae for providing certain pressure gas.
In use, sending letter when infrared inductor 60 senses when between the head that gripped object has been located in caliper 20
To provide pressed gas to air flue 11 by tracheae, which drives two pistons 40 to divide via air flue 11 for number informing air pump
It is not mobile towards two 20 directions of caliper, as shown in Fig. 2, so that two mandrils 41 push against two calipers 20 respectively makes two
Head is close to gripping objects, chucking power suffered by pressure-sensitive piece of 50 examinations gripped objects, when chucking power reaches pre set force
When, pressure-sensitive piece 50 is informed that air pump without pressure increase or is subtracted with the gas pressure of the corresponding chucking power to ventilation is played
It is small.
When needing to discharge object, control air pump reduces air pressure until stopping being that air flue 11 provides pressure, at this point, in spring
Under the action of 30 power, as shown in Figure 1, object is unclamped on the head of two calipers 20.
In a preferred embodiment of the utility model, the side opposite with mandril 41 of caliper 20 offers sliding slot 21,
The slot bottom of sliding slot 21 is protruded on the head of mandril 41, and the slot bottom of sliding slot 21 is provided with wearing layer 22.Sliding slot 21 has one to mandril 41
Guiding role is determined, so that mandril 41 will not generate the offset on 10 thickness of keeping body to the pushing force of caliper 20.In mandril 41
During pushing against caliper 20, can inevitably it be produced relative sliding between mandril 41 and caliper 20, and wearing layer 22 can have
Effect reduces abrasion of the sliding to caliper 20.
The utility model is pivoted to complete holding action, compared to the prior art using the stretching pushing and pressing caliper 20 of mandril 41
Using link mechanism drive gripper clamp, have the advantages that compact-sized, driving force is big.
Above embodiments are only the exemplary embodiment of the utility model, are not used in limitation the utility model, this is practical new
The protection scope of type is defined by the claims.Those skilled in the art can be in the essence and protection scope of the utility model
It is interior, various modifications or equivalent replacements are made to the utility model, this modification or equivalent replacement also should be regarded as falling in originally practical new
In the protection scope of type.
