Detailed Description

The following describes the present invention in further detail with reference to the accompanying fig. 1-4.

As shown in figures 1-4, the utility model relates to a gear shaper for processing nine teeth of a worm shaft, which comprises a fixing ring 1, wherein the fixing ring 1 is fixed on the gear shaper and is used for fixing and processing the worm shaft, a pressing groove 2 is embedded in the upper end surface of the fixing ring 1, the inner surface of the fixing ring 1 is provided with a perforation, the perforation is communicated with the pressing groove 2, one end of the perforation close to the circle center of the fixing ring 1 is connected with a pressing block 3 in a sliding way, the other end of the perforation far away from the circle center of the fixing ring 1 is connected with a supporting block 4 in a sliding way, a pressing spring 5 is connected between the supporting block 4 and the pressing block 3, the fixing ring 1 is connected with a pressing cylinder 6 in a sliding way, a pressing push rod 7 is integrally formed on the pressing cylinder 6, the rear end of the supporting block 4 is of an inclined plane structure, the front end of the pressing push rod 7 is connected with the supporting block, insert the worm in solid fixed ring 1, then slide and compress tightly drum 6, compress tightly drum 6 and can drive when gliding and compress tightly push rod 7 and slide, compress tightly push rod 7 and drive when gliding and support tight block 4 and slide, support tight compact block 3 when supporting tight block 4 and slide, make compact block 3 tightly push down the worm, fix the worm.

Support tight piece 4 and compact heap 3 and all slide in perforating, because the rear end that supports tight piece 4 is the inclined plane structure, and compress tightly push rod 7 and support the rear end sliding connection of tight piece 4, the event compresses tightly push rod 7 and just can increase the pressure to tight piece 4 for the one end distance that slides forward, even compact heap 3 is pressed to the side of worm tighter, because compact heap 3 with support tight piece 4 and pass through hold-down spring 5 and connect, event compact heap 3 remains the pressure to the worm throughout, and can prevent compact heap 3 because pressure is too big and cause the damage to the surface of worm.

The integrated into one piece has the drum on solid fixed ring 1, compresses tightly 6 sliding sleeve of drum on the drum, runs through on the drum and is equipped with the fixed orifices, is equipped with the fixed pin on compressing tightly the drum 6, as shown in fig. 2, and the quantity that compresses tightly the drum 6 upper hole is 1, and the quantity that fixed ring 1 upper hole is a plurality of, can increase the frictional force of compact heap 3 to the worm when compressing tightly drum 6 gliding downwards, and the fixed pin is used for fixing compressing tightly drum 6.

The number of the through holes is three, and the through holes are uniformly formed in the inner side of the fixing ring 1, because the through holes are uniformly formed in the inner side of the fixing ring 1, the pressing cylinder 6 can push the abutting blocks 4 simultaneously when sliding, the pressing force of the pressing blocks 3 on the worm is average, and the axial line of the worm and the axial line of the fixing ring 1 are effectively prevented from deviating.

The surface of the pressing block 3 is integrally formed with saw-shaped anti-slip teeth 8.

As shown in fig. 4, in order to improve the stability when fixing the worm, the number of the fixing rings 1 may be two, the two fixing rings 1 are fixed at two sides of the workbench of the gear shaping machine through bolts, when fixing the worm, the worm may be inserted into the two fixing rings 1 first, and then the compressing cylinder 6 slides, the compressing cylinder 6 drives the compressing push rod 7 to move and press the abutting block 4, and the abutting block 4 drives the compressing block 3 to slide, so as to clamp the worm.

The working principle is as follows: the utility model discloses in fixed worm, can insert two solid fixed ring 1 with the worm earlier, then slide again and compress tightly drum 6, it compresses tightly push rod 7 and removes and press to tight piece 4 to compress tightly the drive of drum 6, it slides to drive compact heap 3 to support tight piece 4, thereby press from both sides tight worm, because compact heap 3 with support tight piece 4 and connect through pressure spring 5, so compact heap 3 remains the pressure to the worm all the time, and can prevent compact heap 3 because pressure is too big and cause the damage to the surface of worm, because the perforation evenly sets up in solid fixed ring 1's inboard, can promote simultaneously when compressing tightly drum 6 is gliding and support tight piece 4, so compact heap 3 is average to the pressure of worm, effectively prevent the axis of worm and solid fixed ring 1's axis skew.
