Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
Fig. 1 to Fig. 6 is structural representation of the present utility model.
Reference numeral is wherein: product workpiece A, chuck body 1, cylinder riser 11, clamp 2, positioning convex column 21, cylinder 3, cylinder connecting rod 4, stroke groove 4a, rod body part 41, connecting portion 42, force annular boss 43, spring housing 5, slide opening 5a, locating hole 5b, pull bar screw 5c, port ring surface 51, preloading spring 6, manual draw bar 7.
Fig. 1 to Fig. 6 is structural representation of the present utility model, as shown in the figure, a kind of elasticity clamping structure in advance boring sequence frock clamp of the present utility model, comprise chuck body 1 and clamp 2 and be fixedly mounted in chuck body 1 for the cylinder 3 promoting clamp 2 clamping and positioning product workpiece A in chuck body 1 that exerts a force, the front end of cylinder 3 is fixedly connected with cylinder connecting rod 4, the back side of clamp 2 is installed with the spring housing 5 of joining with cylinder connecting rod 4 slip cap, be provided with in this spring housing 5 to be press-fitted with cylinder connecting rod 4 front end face top to merge and rely on own spring force can promote spring housing 5 to drive clamp 2 to move ahead to exert a force in advance and clamp the preloading spring 6 of product workpiece A, cylinder connecting rod 4 is shaped with and pushes up press-fit with spring housing 5 port ring surface 51 and promote spring housing 5 and drive clamp 2 to exert a force to clamp the force annular boss 43 of product workpiece A, spring housing 5 is at least provided with one for pull spring housing 5 to compress manual draw bar 7 that preloading spring 6 discharges pretightning force.In prior art, for the vertical product workpiece A needing location clamping, because the reason of deadweight often can drop automatically, therefore when product workpiece A clamping, usually operating personnel's holder is needed to buttress product, another hand deactivation switch, which results in the process having a hand to clamp at product workpiece A of operating personnel and be not in safe range, thus easily there is security incident, make operating personnel have to be primarily focused on the line one on hand, namely the labour intensity of employee is added, work under making again employee constantly remain on nervous environment, thus production efficiency is low, unstable product quality.The utility model bores sequence frock clamp for the vertical location clamping of traditional needs, propose the design of a kind of elasticity formed by spring housing and preloading spring clamp system in advance, change traditional rigid clamp mechanism design, extra support power is had in the process that product to be processed workpiece A is got at clamping and unloading, thus avoid falling of product and collide with, liberate the hand of operating personnel, eliminate personal safety accident and product safety accident.
In embodiment, spring housing 5 of the present utility model is shaped with the axially extended slide opening 5a be slidably matched with cylinder connecting rod 4 from rear end face, the front end face of spring housing 5 is shaped with the locating hole 5b of concentric connection slide opening 5a, preloading spring 6 is arranged on the slide opening 5a of spring housing 5) in, and the other end of this preloading spring 6 with the top press-fit of cylinder connecting rod 4 front end face and the diapire phase apical grafting of slide opening 5a.
In embodiment, spring housing 5 spiral is provided with two manual draw bars 7, at a distance of 180 degree of pull bar screw 5c be shaped with for installing manual draw bar 7 on this spring housing 5.Manual draw bar 7 spiral is arranged on spring housing 5, by pulling manual draw bar 7 that spring housing 5 and clamp 2 can be driven to cancel preload pressure to product workpiece A, so just facilitating the clamping of product workpiece A and unloading.
In embodiment, the rear end face of clamp 2 is shaped with positioning convex column 21, and positioning convex column 21 is located with the locating hole 5b of spring housing 5 and is equipped with mutually.
In embodiment, cylinder connecting rod 4 comprises the rod body part 41 of to slide with the slide opening 5a of spring housing 5 and matching and is integrally connected on rod body part 41 breech face and is shaped with externally threaded connecting portion 42, and rod body part 41 is shaped with above-mentioned force annular boss 43 near rear end.
In embodiment, be shaped with two stroke groove 4a that can play position-limiting action while 180 degree before the side face of rod body part 41 being positioned at force annular boss 43, the front end of manual draw bar 7 extend into the direction slide anteroposterior along stroke groove 4a in stroke groove 4a.
In embodiment, cylinder 3 is horizontal thrust cylinder, and this cylinder 3 is fixedly mounted on the cylinder riser 11 of chuck body 1.
In embodiment, between slide opening 5a and rod body part 41, leave the fit clearance being less than 0.3mm.Fit clearance between slide opening 5a and rod body part 41 should not be greater than 0.3mm, and excesssive gap can cause clamp system to swing excessive when clamping between the two, causes the compression point of product inconsistent.
General principle of the present utility model is: after product completes processing, cylinder stroke playbacks, and moves after band dynamic air cylinder connecting rod, loses the preloading spring release distortion of external force extruding, and then promote outside spring housing and clamp reach compression product, ensure that product can not fall and collide with.
When product clamping, operating personnel draw the manual draw bar on spring housing with finger, drive the preloading spring that spring housing compression is inner, vacate clamping space, after product clamping completes, unclamp manual draw bar, spring housing and clamp reach compress product, restart cylinder clamping.
The course of work of the present utility model is as follows:
Product to be processed workpiece A install and unload get time, cylinder 3 does not clamp, preloading spring 6 in spring housing 5 does not deform by external force, spring housing 5 is limited in the farthest of the stroke groove 4a of cylinder connecting rod 4 by manual draw bar 7, now, the clamp 2 being installed on spring housing 5 front end contacts with mounted product workpiece A and implements certain support power and pressure, ensures that product workpiece A does not drop collide with this.
After clamping, operating personnel's double handed start switch, cylinder 3 propulsion cylinder connecting rod 4, in this process, cylinder connecting rod 4 extrudes preloading spring 6, there is deformation and pressure passed to clamp 2 in preloading spring 6, the stroke because of cylinder 3 is greater than the size of the stroke groove 4a of cylinder connecting rod 4, therefore product to be processed workpiece A can be made to be in clamped state.
The beneficial effects of the utility model are:
1, less demanding to the accuracy of manufacture of part, utilize common process equipment to process, cost is low, is convenient to manufacture.
2, be beneficial to operation, have positive guarantee to the personal safety of operating personnel.
3, can prevent from product to be processed from falling to collide with, eliminate product safety accident.
