Jig main body 100 is achieved a fixed connection by connector guide pin 180 with the stationary plane 151 for clamping crossover sub 150, 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 by ring flange on numerically controlled lathe, when replacing fixture 10, it is only necessary to
By fixture 10 and 120 fixed screw disassembling of ring flange, easy disassembly fixture 10.
Jig main body 100 is set as cylindrical structure, avoids be easy to causeing there are more corner on jig main body 100
Operating personnel are accidentally injured on replacing jig main body 100, improve safety coefficient.One of jig main body 100 is arranged on surface
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 side by side in the first storage tank 101, clump weight 140 is placed in the second storage tank 102, correcting block
160 are placed in annular groove 103, and hold-down mechanism 130, clump weight 140 and correcting block 160 are fixed by the fixed mode of screw
In on jig main body 100.Wherein, hold-down mechanism 130 makes product 20 fit closely in the first storage tank for compressing product 20
In 101 so that 20 accurate positioning of product prevents product 20 from shifting in process；Clump weight 140 and correcting block 160 can be with
So that jig main body 100 is kept dynamic equilibrium when being rotated with lathe spindle, will not be shaken in high-speed rotation, avoid pressing from both sides
Tool 10 is shifted with 20 center of gravity of product, is improved lathe grinding revolution and cutting feed, is improved the rotating speed of lathe spindle, effective to improve
Production efficiency and product 20 quality.Optionally, the selection of clump weight 140 and correcting block 160, can be negative by increasing fixture 10
The laggard action balance experiment of weight, and then suitable clump weight 140 and correcting block 160 are selected, it avoids generating vibration effect to lathe.
Therefore, the assembly of the digital control lathe clamper 10 of the utility model needs that crossover sub 150 and lathe will be clamped in advance
It turns round pull rod 110 to fix, further assembles ring flange and jig main body 100, and then upper machine tool rotary pull rod 110 will be connected
The one end for clamping crossover sub 150 is sheathed in ring flange, and by jig main body 100 and is clamped using connector guide pin 180
Crossover sub 150 is fixedly connected, and is connected to make jig main body 100 be 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, and product 20 is avoided to shift.
Further, corresponding clump 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, to complete the clamping to product 20.
After processing is completed, the screw above hold-down mechanism 130 is unscrewed 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 made to unclamp the clamping to product 20, with easily by product 20 from the first storage tank
It is taken out in 101.Therefore, the utility model processes the product 20 of same specification, need not repeat adjustment hold-down mechanism 130, counterweight
The position of block 140 and correcting block 160, and it is fast and reliable to the positioning accuracy of product 20, production efficiency and production can be effectively improved
20 quality of product.
Therefore, it is uneven can to solve power when the processing of product 20 in the prior art for the fixture of the numerically controlled lathe of the utility model
The problems such as weighing apparatus, usual big, size are difficult to management and control, rapidly and reliably to the positioning accuracy of product 20, raising comes into force efficiency and product
20 qualities.
The utility model also provides a kind of numerically controlled lathe, including main shaft and turning attachment, the structure and the prior art of main shaft
Similar, turning attachment is the turning attachment of above-described embodiment, and concrete structure no longer specifically repeats herein.
It is different from the prior art, digital control lathe clamper provided by the utility model and the numerically controlled lathe using the fixture,
Wherein fixture includes machine tool rotary pull rod, jig main body and hold-down mechanism, and jig main body is fixed on machine tool rotary pull rod, wherein
At least the first storage tank is provided on jig main body, for housing product, hold-down mechanism houses the first storage tank side by side with product
In the first storage tank, and the hold-down mechanism is that product is lock onto the first storage tank by lateral expansion briquetting for extending to the outside
Between hold-down mechanism.Therefore, the digital control lathe clamper of the utility model can clamp product by hold-down mechanism, and product is made to fix
It is tightly fastened in storage tank, and ensures clamping force of the fixture to product, can avoid product when processing and shift, also, this practicality
It is novel also by the way that clump weight and correcting block and flange are arranged on fixture, can be further assured that product lathe in processing can be kept
Dynamic equilibrium avoids generating vibration effect to lathe, improves production efficiency and improves product quality.
