Solve a series of problems caused by power is uneven, inertia is big in processing of product 20, it is effective improve production efficiency and
Product quality.
With continued reference to Fig. 1-Fig. 7, illustrate the work of the digital control lathe clamper 10 of the present invention with a specific embodiment below
Principle.In the present embodiment, digital control lathe clamper 10 includes：Machine tool rotary pull bar 110, jig main body 100, hold-down mechanism 130,
Balancing weight 140, crossover sub 150, flange mechanism 120 and correcting block 160 are clamped, flange mechanism 120 refers to ring flange here.
Wherein, clamping crossover sub 150 includes the stationary plane 151 of a circular design, for stationary fixture main body 100, Gu
The opposite side for determining face 151 stretches out to form the threaded screwed hole (not shown) of inwall setting, machine tool rotary pull bar 110
End be correspondingly arranged on screw thread 111, by machine tool rotary pull bar 110 be correspondingly arranged on screw thread 111 end be inserted in clamping turn
In the screwed hole of changing-over first 150, it is fixedly connected so that clamping crossover sub 150 with machine tool rotary pull bar 110.
Jig main body 100 is fixed on by way of screw fixation on the stationary plane 151 for clamping crossover sub 150, for example,
Jig main body 100 is achieved a fixed connection by joint guide pin 180 with clamping the stationary plane 151 of crossover sub 150, and it is not single
Jig main body 100 can be made to be fixed on the stationary plane 151 for clamping crossover sub 150, but also can be clamped to jig main body 100
Product 20 functions such as guiding, positioning, tuningout, anti-attrition are realized when being processed.
Ring flange is sheathed on the periphery for clamping crossover sub 150, and one end and the ring flange 120 of jig main body 100 pass through spiral shell
Nail is fixedly connected.Wherein, jig main body 100 can be fixed on numerically controlled lathe by ring flange, when changing fixture 10, it is only necessary to
The screw disassembling that fixture 10 and ring flange 120 are fixed, easy disassembly fixture 10.
Jig main body 100 is arranged to cylindrical structure, avoids more corner on jig main body 100 being present, easily causes
Operating personnel are accidentally injured on jig main body 100 is changed, improve safety coefficient.Set on one of surface of jig main body 100
There are the first storage tank 101 and the second storage tank 102, and the avris of jig main body 100 is provided with annular groove 103, wherein, product 20
And hold-down mechanism 130 is placed in the first storage tank 101 side by side, balancing weight 140 is placed in the second storage tank 102, correcting block
160 are placed in annular groove 103, and hold-down mechanism 130, balancing weight 140 and correcting block 160 are fixed by way of screw fixation
In on jig main body 100.Wherein, hold-down mechanism 130 is used to compress product 20, product 20 is brought into close contact in the first storage tank
In 101 so that the accurate positioning of product 20, prevent product 20 from shifting in process；Balancing weight 140 and correcting block 160 can be with
Jig main body 100 is kept dynamic equilibrium when being rotated with lathe spindle, will not also be shaken when high-speed rotation, avoid pressing from both sides
Tool 10 shifts with the center of gravity of product 20, improves lathe grinding revolution and cutting feed, improves the rotating speed of lathe spindle, effective to improve
Production efficiency and the quality of product 20.Alternatively, the selection of balancing weight 140 and correcting block 160, can be negative by increasing fixture 10
The laggard action balance experiment of weight, and then suitable balancing weight 140 and correcting block 160 are selected, avoid producing vibration effect to lathe.
Therefore, the assembling of digital control lathe clamper 10 of the invention, it is necessary to will clamp crossover sub 150 and machine tool rotary in advance
Pull bar 110 is fixed, and further assembles ring flange and jig main body 100, and then the clamping that will connect upper machine tool rotary pull bar 110
One end of crossover sub 150 is sheathed in ring flange, and is changed jig main body 100 with clamping using joint guide pin 180
Joint 150 is fixedly connected, and is connected so that jig main body 100 is realized with numerically controlled lathe.
Before processing, product 20 is assemblied in the first storage tank 101 of jig main body 100, while by hold-down mechanism 130
It is fixed in the first storage tank 101, and hold-down mechanism 130 is fixed in the first storage tank 101 by screw so that compacting machine
Structure 130 compresses product 20, avoids product 20 from shifting.
Further, corresponding balancing weight 140 is assemblied in the second storage tank 102 of jig main body 100, while high-ranking officers
Positive block 160 is assemblied in annular groove 103, so as to complete the clamping to product 20.
After machining, the screw above hold-down mechanism 130 is outwarded winding so that the pressing means 133 of hold-down mechanism 130 are not
Decline the wedge-shaped cell wall of extruding again, hold-down mechanism is unclamped the clamping to product 20, with easily by product 20 from the first storage tank
Taken out in 101.Therefore, the present invention processes the product 20 of same specification, it is not necessary to repeats adjustment hold-down mechanism 130, balancing weight 140
And the position of correcting block 160, and it is fast and reliable to the positioning precision of product 20, production efficiency and the product of product 20 can be effectively improved
Matter.
Therefore, the fixture of numerically controlled lathe of the invention, it is uneven, used can to solve power during the processing of product 20 in the prior art
The problems such as being difficult to management and control with big, size, to the positioning precision of product 20 rapidly and reliably, raising comes into force efficiency and the product of product 20
Matter.
The present invention also provides a kind of numerically controlled lathe, including main shaft and turning attachment, the structure of main shaft similarly to the prior art,
Turning attachment is the turning attachment of above-described embodiment, and its concrete structure no longer specifically repeats herein.
Prior art, digital control lathe clamper provided by the present invention and the numerically controlled lathe using the fixture are different from, wherein
Fixture includes machine tool rotary pull bar, jig main body and hold-down mechanism, and jig main body is fixed on machine tool rotary pull bar, wherein fixture
It is provided with least the first storage tank in main body, the first storage tank is used to housing product, and hold-down mechanism and product are placed in the side by side
One storage tank, and the hold-down mechanism is lateral expansion briquetting, for external expansion, product to be lock onto into the first storage tank and pressure
Between tight mechanism.Therefore, digital control lathe clamper of the invention can clamp product by hold-down mechanism, fix product fixing compact
In in storage tank, and ensure clamping force of the fixture to product, product during processing can be avoided to shift, also, the present invention also by
Balancing weight and correcting block and flange are set on fixture, can be further assured that product lathe in processing can keep dynamic equilibrium, keep away
