Description
Technical field
The utility model is related to electric upsetting of air valve forging equipment field, especially a kind of clamp centralising device.
Background technology
Electric upsetter is the important electric upsetting equipment for making automotive engine valves, and clamp is indispensable work on electric upsetter
Clamps.
Clamping mechanism is made up of left and right two parts, in electric upsetting of air valve forming process, and this two parts is pressed from both sides to middle movement
The firmly bar portion of valve blank.The clamp of country's electric upsetter is when clamping workpiece at present, and a side position of clamp is fixed, opposite side
Clamp is moved to center, is moved to always and workpiece bar portion is clipped on the clamp of affixed side, and the right position of workpiece is by fixation
The positioning of side.During electric upsetting, the position of affixed side does not adjust substantially.
During electric upsetting of air valve, due to there is the clamping force increased between left and right clamp and workpiece bar portion, and workpiece
Bar portion is moved upwards relative to clamp and fixture block always, and the fixture block of clamp front end is contacted with bar portion, and fixture block can be worn out semicircle
Groove.Because the side position of clamp one is fixed, therefore with the increase of work pieces process quantity, the fixture block abrasion of affixed side is more and more deeper,
So as to cause clamp to be clamped after workpiece bar portion, its center line can be offset to affixed side.
This skew can be to making the valve that upsetting goes out produce inclined head, even bar portion inclination, the defect such as distortion.Following process is made
Into considerable influence, or even produce quality accident.Furthermore, affixed side position adjustment has manually to complete, and can exist and adjust not in place
Destabilizing factor.
The content of the invention
The utility model overcome shortcoming of the prior art there is provided one kind can be prevented effectively from due to tool part abrasion,
Workman adjusts a kind of clamp automatic centring device of clamped position skew caused by the factor such as not in place.
In order to solve the above-mentioned technical problem, the utility model is achieved through the following technical solutions：
A kind of clamp automatic centring device, including cylinder, chain exit, left sprocket wheel, right sprocket wheel, left chain, right chain, chain
Bar section, linkage section, chain spring section, fixed seat, left clamp, right clamp, gear, gear shaft, rack and return spring, cylinder position
In the bottom of device, chain exit is set in the upper end of cylinder, protruded upward from chain exit symmetrical left chain and
Right chain, left chain and right chain are divided into three parts, chain segment, linkage section and chain spring section, chain segment, linkage section and chain
Bar spring section is in turn connected to form loop configuration, the chain segment of left chain and right chain respectively with the left chain on the upside of cylinder
Wheel, right sprocket wheel be meshed, and bypassed upwards from outside positioned at device upper left, the left clamp of upper-right position, right clamp, and respectively with
Left clamp is connected with the gear shaft inside right clamp, is connected vertically downward with linkage section after bypassing left clamp, right clamp, linkage section
Lower end connection chain spring section, the bottom of chain spring section is fixedly connected with fixed seat, is distinguished on described left clamp, right clamp
Be provided with return spring, left clamp, right clamp be internally provided with gear shaft on the gear and rack structure being engaged, gear with
Chain segment is meshed.
Moreover, having space in the middle part of described left chain and the linkage section of right chain, chain segment is passed through from space.
Moreover, described left clamp and right clamp are arranged on guide rail (not marked in figure), in left chain and right chain band
When moving gear is rotated on rack, left clamp and right clamp do synchronous clamping or synchronous release action.
Moreover, the quantity of described return spring is two, each one on left clamp and right clamp, and it is symmetrical arranged, returns
Position spring provides left clamp, the pulling force that right clamp is kept in the center.
Compared with prior art, the beneficial effects of the utility model are：The position of chain, transmission mechanism and sprocket wheel and cylinder
The uniformity for the speed and strength that ensure that two clamps in left and right is put, the clamp of left and right two can be made to keep synchronous working, kept away
Exempted to wear and tear due to tool part, clamp Centre position deviation caused by workman's adjustment factor such as not in place so as to realize clamp from
Dynamic centering, this eliminates the inclined head in upsetting, the defect such as bar portion is tilted, and reduces the workload of subsequent process.
Brief description of the drawings
Fig. 1 is the utility model overall structure diagram.
Fig. 2 is the utility model partial structural diagram.
Wherein, 1 is right clamp, and 2 be return spring, and 3 be right chain, and 4 be linkage section, and 5 be chain spring section, and 6 be fixation
Seat, 7 be right sprocket wheel, and 8 be chain exit, and 9 be cylinder, and 10 be left clamp, and 11 be left chain, and 12 be left sprocket wheel, and 13 be gear, 14
