Description
Technical field:
The invention belongs to aero-engine manufacturing technology field, be specifically related to a kind of large thin-wall casing processing damping clamp.
Background technology:
Large thin-wall casing has that diameter is large, wall thickness is thin and the feature such as poor rigidity, and add man-hour cutting stress large, processing parts easily produces vibration, and working (machining) efficiency is lower.In order to improve crudy, many group fixtures can be adopted in the processing of different operation to treat processing parts and carry out clamping, many group fixtures improve design difficulty and manufacturing cost, and its clamping difficulty also improves thereupon.
Summary of the invention:
For solving prior art Problems existing, the present invention proposes a kind of structure simple, good damping effect, the large thin-wall casing processing damping clamp that cost is low.
For achieving the above object, the present invention is by the following technical solutions: a kind of large thin-wall casing processing damping clamp, comprise pedestal, described pedestal is provided with support, support is made up of the first bracket component, the second bracket component, the 3rd bracket component and the 4th bracket component, and described first bracket component, the second bracket component, the 3rd bracket component and the 4th bracket component are fixedly connected sequentially from the bottom to top; 4th bracket component is provided with the first compact heap; 3rd bracket component is provided with the first back-up block; Second bracket component is provided with the second back-up block; First bracket component is provided with the second compact heap, described first back-up block front end is provided with elastomeric layer, and the front end of described second back-up block is provided with two support shank, and each support shank front end is provided with elastomeric layer; Described first back-up block and the second back-up block rear end are provided with puller bolt, and the first compact heap and the second compact heap top are provided with hold-down bolt.
Pedestal below described second compact heap is provided with alignment pin.
Beneficial effect of the present invention: structure is simple, good damping effect and cost is low.
Accompanying drawing illustrates:
Fig. 1 is the structural representation of one embodiment of the present of invention;
Wherein: 1-pedestal, 2-first compact heap, 3-second compact heap, 4-first back-up block, 5-second back-up block, 6-part to be processed, 7-alignment pin, 8-first bracket component, 9-second bracket component, 10-the 3rd bracket component, 11-the 4th bracket component, 12-puller bolt, 13-hold-down bolt.
Detailed description of the invention:
Below in conjunction with drawings and Examples, the present invention is described in further details, as shown in Figure 1, a kind of large thin-wall casing processing damping clamp, comprise pedestal 1, described pedestal 1 is provided with support, support is made up of the first bracket component 8, second bracket component 9, the 3rd bracket component 10 and the 4th bracket component 11, and described first bracket component 8, second bracket component 9, the 3rd bracket component 10 and the 4th bracket component 11 are fixedly connected sequentially from the bottom to top; 4th bracket component 11 is provided with the first compact heap 2; 3rd bracket component 10 is provided with the first back-up block 4; Second bracket component 9 is provided with the second back-up block 5; First bracket component 80 is provided with the second compact heap 3, described first back-up block 4 front end is provided with the elastomeric layer that rubber is made, the front end of described second back-up block 5 is provided with two support shank, and each support shank front end is provided with the elastomeric layer that rubber is made; Described first back-up block 4 and the second back-up block 5 rear end are provided with puller bolt 12, and the first compact heap 2 and the second compact heap 3 top are provided with hold-down bolt 13.Pedestal 1 below described second compact heap 3 is provided with alignment pin 7.
Before Vehicle Processing, be first placed on pedestal 1 by part 6 to be processed, by the position centering of alignment pin 7 by part 6 to be processed, the lower surface of then treating processing parts 6 by the hold-down bolt 13 on the second compact heap 3 is fixed.The puller bolt 12 of the first back-up block 4 rear end is tightened, makes the front end of the first back-up block 4 be adjacent to the outer wall of part 6 to be processed, then pedestal 1 is arranged on lathe, and carry out the Vehicle Processing of the upper surface of part 6 to be processed.
Behind the upper surface of the complete part 6 to be processed of Vehicle Processing, first compact heap 2 is compressed by hold-down bolt 13, and then secure the upper surface of part 6 to be processed, then the front end of the second back-up block 5 is adjacent to the outer wall of part 6 to be processed by puller bolt 12, thus can the inside of Vehicle Processing part 6 to be processed, in the present embodiment, the first compact heap 2 quantity is 16, the quantity of the first back-up block 4 and the second back-up block 5 is 14, be arranged on the periphery of part 6 to be processed uniformly, the rubber layer of the front end of the first back-up block 4 and the second back-up block 5 effectively can reduce the vibration in processing, improve crudy.
After Vehicle Processing, take off pedestal 1 and be fixed on milling machine, Milling Machining is carried out in the inside of then treating processing parts 6.Only need one group of fixture in two operations, and then decrease and change the time of fixture and the cost of fixture, and then improve production efficiency.
