A kind of metal shell processes clamping device
The utility model belongs to precision manufactureing processing technique field, more particularly to a kind of metal shell processing clamping device.
In metal shell process, it is required for using CNC equipment and is processed, such as phone housing or center
Production, be required for carrying out deburring using CNC, but traditional CNC process equipments, the clamping effect of its clamping device is not good,
Particularly when relatively thin metal shell class product is processed, workpiece displacement is easily caused in process, causes to damage
Bad workpiece, wastes raw material；If adjusting the clamping dynamics of clamping device, although metal shell can be clamped, but hold
Impression is easily left on metal shell, causes workpiece to turn into defect ware.
Utility model content

There is handle.
Further, the cylinder is rotary cylinder.
Further, the loading plate is plastic cement material, and upper surface is provided with corresponding locating slot according to workpiece shape.
Further, the support column is distributed in four angles of cushion cap.
Compared with prior art, the utility model has the following advantages that：
Metal shell of the present utility model processes clamping device, and design science is reasonable, by the magnet coil for sucking mechanism
With vacuum tube collective effect, by metal shell absorption on loading plate, the briquetting of pressing plate and cylinder control is additionally provided with to metal-back
Body is compressed, it is ensured that metal shell will not shift in process, and will not also be damaged by the way of absorption
Hinder metal shell, and pressing plate also plays protective effect to housing, further ensures being smoothed out for metal shell processing.
Brief description of the drawings
Fig. 1 is the schematic diagram of the preferred embodiment of the utility model one.
A kind of metal shell of the utility model processing clamping device is made into one below in conjunction with specific embodiment and accompanying drawing
Step is described in detail.
As shown in figure 1, in a preferred embodiment, metal shell processing clamping device of the present utility model includes the He of base 1
The cushion cap 2 of the top of base 1 is arranged on, support column 3 is additionally provided between base 1 and cushion cap 2, cushion cap 2 is fixed on bottom by support column 3
On seat 1, in the present embodiment, support column 3 is separately positioned on four angles of cushion cap 2, Stability Analysis of Structures；Carrying is additionally provided with cushion cap 2
Plate 4, loading plate 4 is used to place in processed product, the present embodiment, and loading plate 4 is plastic cement material, can effectively protect to be processed
Product, will not cause damage, and be additionally provided with loading plate 4 positioning corresponding with product during being fixedly clamped to product
Groove, can be loaded to product easily and fast.
Multiple cylinders 5 are provided with the side of cushion cap 2, and are additionally provided with the piston rod of cylinder 5 briquetting 6, the present embodiment
Middle cylinder 5 is rotary cylinder, and briquetting 6 can be driven to move up and down and rotate, in the course of work, and cylinder 5 drives briquetting 6 to revolve
Turn to push, processed product is clamped on loading plate 4, after machining, then control the rotation rising of briquetting 6, release what is clamped
State.It is that the side of cushion cap 2 is provided with cylinder 5 and compressed in the present embodiment, gas can also be respectively provided with multiple sides of cushion cap 2
Cylinder 5 is compressed, and can also reach identical technique effect.
Also include being used to suck multiple locking devices 7 of workpiece, locking device 7 is arranged on base 1, and through holding
Platform 2 and loading plate 4, locking device 7 include magnet coil 71 and the vacuum tube 72 being arranged in magnet coil 71, wherein electromagnetic wire
Circle 71 can produce magnetic force after being powered, and have certain suction to intermetallic composite coating product, vacuum tube 72 can by converted products with
The contact surface of loading plate 4 is vacuumized, and vacuum suction by processed product absorption tightly on loading plate 4,
Further improve clamping effect.
In order to improve clamping effect again, a pressing plate 8 for being used to compress workpiece is also provided with, the pressing plate 8 includes plastic cement
Layer 82 and metal level 83, metal level 83 are contacted on plastic layer 82 using plastic layer 82 with processed product, will not damage production
Product, moreover it is possible to certain protective role is played to product, and metal level 83 utilizes the suction of own wt and magnet coil 71, can
Preferably product is compressed.Pressing plate 8 is captured for convenience, and handle 81 is additionally provided with the metal level 83 of pressing plate 8.
Rationally, clamping effect towards processed products is good for the utility model design science, and 6 pairs of briquetting is driven using cylinder 5
Processed product is compressed, and is also sucked, is also set up in addition towards processed products using magnet coil 71 and vacuum tube 72
Pressing plate 8 is compressed, and the above a variety of devices ensure that processed product clamped condition is stable, will not move in process
It is dynamic, it is ensured that processing is normally carried out, converted products steady quality.
Although being to combine embodiments above to carry out to description of the present utility model, it is familiar with the art
Personnel many replacements, modifications and variations can be carried out according to above-mentioned content, are obvious.Therefore, it is all such
