Specific embodiment

Do detailed introduction below in conjunction with 1,2 pair of the utility model of attached drawing: the utility model includes lathe equipments 1, uses In the fixture 2 of clamping processed product, 2 clamping of fixture is installed on the knife rest 11 of lathe equipments 1 on the chuck of lathe equipments 1 There is spinning insert 3；Spinning insert 3 include knife handle 31, spinning wheel 32, spinning wheel 32 is mounted on one end of knife handle 31, knife handle 31 other end is fixedly mounted on the knife rest 11 of lathe equipments 1, and the spinning end face 32-1 of spinning wheel 32 is directed to production to be processed At the radially-outer surface of product 4.By the spinning end face 32-1 of spinning wheel 32 towards processed products 4 radially-outer surface slightly revolved Pressure and smart spinning, the specific process steps are as follows:

Firstly, carry out thick spinning, when thick spinning, the revolving speed control of fixture of the lathe equipments 1 by clamping on chuck exists The bite general control of 2000-2500r/min, knife rest pass through spinning in 1.5-2.5mm, feed speed F=1500mm/min The spinning end face 32-1 of wheel 32 makes processed product 4 carry out rotary pressing processing repeatedly from outside to inside, to guarantee processed product 4 Wall thickness finally puts 0.5-0.6mm surplus to smart spinning；

Secondly, carry out smart spinning, when smart spinning, the revolving speed of lathe equipments 1 controls constant, the bite general control of knife rest In 0.5-0.6mm, feed speed F=300-500mm/min, the spinning end face 32-1 of spinning wheel 32 by processed product 4 by It is outer and interior to carry out repeatedly rotary pressing processing (substantially in place, surface slightly has unevenness phenomenon to size, and passing through finishing improves)；

Finally, finished, when finishing, the rotation of knife rest 11 in lathe equipments 1 carries out cutter changing, by spinning knife Tool 3 is replaced with common lathe tool, finishes to the product after thick spinning, smart spinning, makes product size in place, surface Beautiful (water pump of lathe equipments 1 need to be opened when being finished).

Spinning insert 3 further includes bearing 33, connecting rod 34, and bearing 33 is mounted on the inside of spinning wheel 32, and connecting rod 34 It tightens spinning wheel 32 is fixed on knife handle 31 across 33 inner diameter hole of bearing and by bolt 5.

In order to make spinning insert 3 embody better stability in spinning process, there are two the settings of bearing 33, two axis The 33 inside two end faces for being separately mounted to spinning wheel 32 are held, and connecting rod 34 passes through two 33 inner diameter holes of bearing and passes through bolt 5 tighten spinning wheel 32 are fixed on knife handle 31.

One end of connecting rod 34 is T-shaped structure, and gasket 6 is equipped between the end and bearing 33；The other end is ladder Structure, and the end is tightened with bolt 5；31 end of knife handle compatible with connecting rod 34 is equipped with the through-hole interted for connecting rod 34 31-1, and raised 31-2 is extended at the inner wall radial direction of through-hole 31-1, through-hole 31-1 is divided by stepped hole shape by raised 31-2, That is: one end of through-hole 31-1 can play limitation connection for placing bolt 5, raised 31-2 for interting connecting rod 34, the other end Bar 34 is moved radially through-hole 31-1's, while playing the role of the axis locking of connecting rod 34 Yu bolt 5, and can be by bolt 5 It is embedded in knife handle 31, plays beautiful effect.

Spinning end face 32-1 is located at the front end of spinning wheel 32, and the rear end of spinning wheel 32 is column structure, and spinning wheel 32 Front end external diameter be greater than rear end outer diameter；Being directed to the spinning end face 32-1 at the radially-outer surface of processed product 4 is arcwall face End, the spinning wheel 32 are handled by special process, and hardness can reach HRC60-65, and ti coat on diamond, and wear-resisting property is good.

It is in angle a between 31 end of knife handle being connected with spinning insert 3 and the main body of knife handle 31, and angle a is 150 ° to 170 °, It can guarantee that the contact surface of spinning wheel and processed product 4 increases, so that 4 surface of processed product for guaranteeing that spinning is crossed is more flat Whole, cutter life is longer.

As shown in Fig. 3, one end of fixture 2 is used for clamping processed product 4, and is in contact with 4 surface of processed product The end face be rough surface, i.e., by surface progress pulse processing aspects to increase the frictional force with 4 surface of processed product；Separately One end is connected through a screw thread mode and is mutually fixedly connected with the chuck of lathe equipments 1.

The utility model is not limited to above embodiment, makees any variation no matter constituting in its shape or material, all It is to be designed using structure provided by the utility model, is all a kind of deformation of the utility model, is considered as practical new at this Within type protection scope.
