The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is further described.
illustrated in figures 1 and 2ly rush the tooth riveting machine for the utility model multiple spot, comprise device for revolving and driving, circular cutting disk 12, positioning disk 13 and rush tooth riveting cutter 14, described positioning disk 13 is positioned at the center of described circular cutting disk 12 and fixes with base, described circular cutting disk 12 is driven by described device for revolving and driving, be evenly equipped with some sections screw type guide grooves 18 on described circular cutting disk 12, be evenly equipped with some gathering sills 19 on described positioning disk, the quantity of the quantity of described gathering sill 19 and described screw type guide groove 18 is corresponding, the described tooth riveting cutter 14 that rushes is arranged in described gathering sill 19, the described rear portion that rushes the tooth riveting cutter is provided with pilot pin 6, described pilot pin 6 is positioned at described screw type guide groove 18 and can moves along described screw type guide groove 18.
Described device for revolving and driving comprises servomotor 7, pinion 10 and bull gear 11, and described pinion 10 is driven by described servomotor 7, and described bull gear 11 is fixed in the outer ring of described circular cutting disk 12, described pinion 10 and described bull gear 11 engagements.
The center of described positioning disk is provided with product orientation piece 9, is provided with auxiliary clamping device directly over described product orientation piece 9.Described auxiliary clamping device comprises clamping cylinder 1, briquetting support 2, power transmission piece 3 and return cylinder 4, described power is transmitted piece and is located on described briquetting support, described clamping cylinder is located at the top that described power is transmitted piece, described return cylinder is located at the below of described briquetting support, and the power of clamping cylinder 1 is transmitted piece by power and compressed product.The below of described briquetting support is provided with displacement transducer 5.
Servomotor is realized moment amplification by pinion 10 and bull gear 11, and by the screw type guide groove on circular cutting disk 12, power is delivered to and rushes tooth riveting cutter 14; When rushing after tooth riveted joint completes, the servomotor counter-rotating drives circular cutting disk 12 and is returned to initial point, rushes tooth riveting cutter 14 at the screw type guide groove and rushes return under the effect of the pilot pin 6 on the tooth riveting cutter.
As shown in Figure 3, the control valve assembly of automobile booster comprises control valve seat 21 and control valve push rod 22.As shown in Figure 4 and Figure 5, workpiece (the control valve assembly of automobile booster) is directly located by the product orientation piece, and the quality of location directly has influence on the precision of rushing tooth.The strict locating piece length dimension L that controls can guarantee workpiece locating surface and the distance A of rushing tooth riveted joint cutter, thereby obtain definite riveted joint position B; Strict product orientation piece D outer diameter and the axiality of locating hole inner diameter d and the radial clearance of product and locating hole inner diameter d controlled, thus the degree of depth that guarantees the multiple spot riveted joint is even.
The utility model multiple spot rushes the tooth riveting machine and adopts servomotor as motive power, controls by PLC, can control the riveted joint degree of depth, and eliminate interiors of products end play by the displacement transducer FEEDBACK CONTROL, has reliable precision.Shaftless to the gap in order to solve between the rear control valve seat of riveted joint and control valve push rod, the utility model adopts a kind of method of FEEDBACK CONTROL to solve.The method adopts displacement transducer and PLC that the displacement data collection is calculated.During workpiece pressing, control valve seat and control valve ball head of pushing rod are compacted for the first time for clamping cylinder, and end play is 0, and displacement transducer carries out data acquisition, is defined as " zero point ".After rushing tooth, clamping cylinder retracts, and the control valve push rod is drawn out under the effect of product self spring force, produces the trend in gap with control valve seat, and displacement transducer was collected data and compared with " zero-bit " this moment.If in allowing the end play scope, riveted joint is completed; If exceed the end play allowed band, dentures continues at a slow speed, until end play reaches in allowed band.
