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.
