Dynamic pressure arm lower end is engaged, ejection slider movement, is driven and is swung pressure arm rotation, spring clamp mechanism compression or elongation.
Preferably, two swing pressure arms are arranged in the roll pin.
Preferably, the spring clamp mechanism includes the parallel spring base being fixed on substrate, mounted on spring
Spring and the knock pin inconsistent with swinging pressure arm lower end, described knock pin one end in seat are acted against on spring, other end top
It leans against and swings pressure arm lower end.
Preferably, the driving mechanism uses single action cylinder mechanism, cylinder ventilation, driving ejection slider perpendicular to
Substrate moves up and down, and the ejection slider presents pyramidal structure wide under point, and ejection slider moves upwards, and spring is retracted, and swings
Pressure arm unclamps workpiece；The cylinder is died, and ejection slider moves downward, and spring elongation swings pressure arm and clamps workpiece.
The utility model obtain advantageous effect be：Positioning and clamping mechanism is set in substrate upper end, if substrate lower end is set
Dry spring clamp mechanism and driving mechanism, spring clamp mechanism are corresponded with the swing pressure arm in positioning and clamping mechanism, are realized
Workpiece is clamped and is positioned；The ejection slider of driving mechanism with swing pressure arm be engaged, further with spring clamp mechanism
Interaction, so as to fulfill being clamped or unclamping to workpiece；The utility model is simple in sturcture, ingenious in design, easy to use, only
It needs once-through operation that clamping and release can be realized, saves beat, occupy little space.
Description of the drawings
Fig. 1 is the structure diagram of the utility model；
Fig. 2 is state diagram when the utility model clamps workpiece；
Fig. 3 is state diagram when the utility model unclamps workpiece.
Specific embodiment
The utility model is further described in the following with reference to the drawings and specific embodiments.
As shown in Figure 1, a kind of spring positioning clamping device of the utility model, including substrate 1, positioning and clamping mechanism 2,
Spring clamp mechanism 3 and driving mechanism 4, substrate 1 are used as supporting body, and positioning and clamping mechanism 2 is vertically set on the upper end of substrate 1,
For locating clip clamping of workpieces 5, spring clamp mechanism 3 and driving mechanism 4 are arranged on the lower end of substrate 1, the ejection in driving mechanism 4
When sliding block 41 does not move, spring clamp mechanism 3 extends, and positioning and clamping mechanism 2 clamps workpiece 5；Ejection slider in driving mechanism 4
41 actions, when moving upwards, spring clamp mechanism 3 is shunk, and positioning and clamping mechanism 2 unclamps workpiece 5.
As Figure 2-3, positioning and clamping mechanism 2 includes set pin sleeve 21, roll pin 22 and several swing pressure arms
23, set pin sleeve 21 is fixed on substrate 1, and roll pin 22 is set in set pin sleeve 21, perpendicular to substrate 1, for workpiece 5
Positioning, several swing pressure arms 23 be uniformly arranged in roll pin 22, middle part is hinged on positioning by rotational pin 24
On guide 21, upper end stretches out roll pin 22 and is externally provided with taper grab 231, lower end side with spring clamp mechanism 3
Knock pin 33 is inconsistent, and the top and bottom for swinging pressure arm 23 are rotated around rotational pin 24, forms lever-type structure；This practicality is new
Two swing pressure arms 23 are arranged in the roll pin 22 of type.
Spring clamp mechanism 3 and the swing pressure arm 23 of positioning and clamping mechanism 2 correspond, including spring base 31, spring 32
With knock pin 33, on substrate 1, spring 32 is mounted in spring base 31 the parallel fixed setting of spring base 31,33 one end of knock pin
It acts against on spring 31, the other end, which acts against, swings 23 lower end side of pressure arm.When driving mechanism 4 is failure to actuate, spring clamp mechanism 3
Knock pin 33 swing pressure arm 23 lower ends by two and compress, swing 23 upper end of pressure arm and rotated around rotational pin 24, two swing pressure
23 upper end of arm is opposite to open, and realizes the clamping to workpiece 5.
Driving mechanism 4 uses single action cylinder mechanism, cylinder ventilation, and driving ejection slider 41 moves up and down perpendicular to substrate 1,
Ejection slider 41 presents pyramidal structure wide under point, and ejection slider 41 moves upwards, and spring 32 is retracted, and swings pressure arm 23 and unclamps work
Part 5；Cylinder is died, and ejection slider 41 moves downward, and spring 32 extends, and is swung pressure arm 23 and is clamped workpiece 5.
The principle of the utility model is：Single action cylinder stuffiness first places workpiece 5 on substrate 1, by hollow fixed
Periphery progress just positioning of position 22 head of pin with taper, since the taper grab 231 for swinging 23 upper end of pressure arm also has centainly
Taper, therefore workpiece 5 can be smoothly pressed into along 22 head of roll pin under taper grab 231, pressure is swung at this time
The upper end rotation of arm 23 is inwardly retracted, and the lower end for swinging pressure arm 23 is flared out, and spring 32 is compressed, workpiece 5 and set pin sleeve
After the fitting completely of 21 positioning surface, the spring 32 compressed discharges elongation, and the lower end for swinging pressure arm 23 is inwardly compressed, and swings pressure
The upper end rotation of arm 23 is flared out, and taper grab 231 clamps workpiece 5, completes the installation of workpiece 5.It needs to remove workpiece 5
When, single action cylinder ventilation, driving mechanism 4 acts, and ejection slider 41, which moves upwards, can unclamp workpiece 5, disconnects source of the gas, single action gas
The spring that cylinder interior carries makes driving mechanism 4 act again, and ejection slider 41 moves downward, and the release of spring 32 compressed is stretched
It is long, the lower end for swinging pressure arm 23 is inwardly compressed, the upper end rotation for swinging pressure arm 23 is flared out, and device is in nature and clamps shape
State.
