Detailed description of the invention
The technical solution of the utility model is further illustrated by detailed description of the invention below in conjunction with accompanying drawing.
As shown in Figure 1, Figure 2, shown in Fig. 3 and Fig. 4, the left and right part common fixture of automobile luggage racks; Comprise main bridge plate 1, Horizontal clamp 200 and vertical fixture 300;
Described locating piece 4 is symmetrical structure, and its left and right sides is respectively arranged with the station for supporting described left and right part 11;
Described Horizontal clamp 200 comprises rotary cylinder 5 and upper-lower compacting block 6, and the rotating output shaft of described rotary cylinder 6 is vertically arrange, described upper-lower compacting block 6 is installed on described rotating output shaft; Not during clamping, described upper-lower compacting block 6 is not positioned at Working position, and during clamping, the rotating output shaft of described rotary cylinder 5 drives described upper-lower compacting block 6 to turn to Working position by described left and right part upper-lower compacting;
Described vertical fixture 300 comprises side pressure cylinder 7 and left and right compact heap 8, and the side pressure output shaft of described side pressure cylinder 7 is arranged horizontally, and described left and right compact heap 8 is installed on described side pressure output shaft; During clamping, the side pressure output shaft of described side pressure cylinder 7 drives described left and right compact heap 8 to clamp about the part of described left and right.
Be clipped in lathe overall structure by the left and right part of automobile luggage racks, locating piece 4 is positioned at the position of center line of whole fixture simultaneously, and Horizontal clamp 200 and vertical fixture 300 are all positioned at the left and right sides of described locating piece 4.On left and right directions during clamping, the left end of left workpiece is clamped by left and right clamp 8, and the right-hand member of left workpiece is resisted against described locating piece 4; The left end of right workpiece is resisted against described locating piece 4, and the right-hand member of right workpiece is clamped by left and right clamp 8, and clamping driving source during clamping is provided by side pressure cylinder 7.On above-below direction during clamping, the upper end of left and right part is clamped by upper and lower clamp 6, and the lower end abutment of left and right part is in the upper surface of described locating piece 4, and clamping driving source during clamping is provided by rotary cylinder 5.Clamping, the upper surface of cutter to left and right part processes.
The left and right part of a set of automobile luggage racks is placed on a sleeve clamp with the time-division, and without the need to clamping at twice, and add man-hour, fixture clamping is the same, and procedure can Continuous maching simultaneously.After processing a workpiece, no longer need lathe to stop, move to tool setting again again on an other sleeve clamp, also need to repeat again once when the processing previous work of processing first processes second.So compared with prior art, shorten process time generally, labour intensity drastically increases working (machining) efficiency while reducing.
The side of described locating piece 4 is provided with alignment pin 12, and during clamping, described alignment pin 12 agrees with the locating hole bottom the part of described left and right.The alignment pin 12 being first placed on respective side during the part clamping of left and right is close to side location-plate 4 simultaneously, after completing location, restarts electrical system and left and right part is compressed by rotary cylinder 5 and side pressure cylinder 7.So first located by alignment pin 12, provide a basic support to left and right part, facilitate being fixedly clamped of next step, improve clamping efficiency.
Also comprise rotation the 4th axle 1 and tailstock 2, the two ends of described main bridge plate 1 are connected with described rotation the 4th axle 9, tailstock 10 respectively by rotating shaft, and the bottom of described main bridge plate 1 is provided with emptiness avoiding hole.Described rotation the 4th axle 9 by the processing of emptiness avoiding hole to part lower surface, described left and right, avoids the secondary clamping of left and right part, improves working (machining) efficiency, cost savings manpower after driving described main bridge plate 1 and upper clamping left and right part thereof to revolve turnback.
Length direction along described main bridge plate 3 is linearly provided with multiple described locating piece 4, Horizontal clamp 200 and vertical fixture 300.Because left and right part has certain length, the setting of multiple locating piece 4, is strong point when left and right part provides multiple clamping, improves the stability of clamping; In like manner, the setting of multiple Horizontal clamp 200 and vertical fixture 300 is also like this; In addition, the setting of multiple Horizontal clamp 200 and vertical fixture 300, and be the side being distributed on left and right part, be namely symmetrically and evenly to the extruding force that left and right part provides, avoid the clamping deformation of left and right part, ensure that clamping precision.
Be positioned at the multiple described Horizontal clamp 200 of described locating piece 4 the same side and vertical fixture 300 by same set of electrical system control.By same set of electrical system control, left and right part is placed on after above described locating piece 4, electrical system is regulated to be contacted with left and right part with left and right compact heap 8 by multiple upper-lower compacting block 6 simultaneously and clamp, instead of a part of compact heap is first and left and right part contact gripping, a remaining part contacts again, there is not such sequencing, after the part that left and right part would not occur is fixed, the phenomenon that non-standing part rotates around the point be fixed, thus ensure that the precision of clamping.
The two ends of described main bridge plate 1 are respectively equipped with origin reference location pin 11, and during clamping, two described origin reference location pins agree with the baseline positioning hole being located at two ends bottom the part of described left and right, improve the efficiency of clamping.
Described locating piece 4 is the symmetrical T-type structure be made up of base and upper arm, described base is fixed on described main bridge plate 1, the two sides of described upper arm and the upper surface of described base form the station for supporting described left and right part, and such positioning block structure is simple and easy to processing, reduces cost.
Described upper-lower compacting block 6 is the symmetrical T-type structure be made up of base and upper arm, and the rotating output shaft of described base and described rotary cylinder 5 is fixed, and during clamping, the bottom surface of described upper arm contacts with described left and right part presses.Described base is the large end of volume, and described upper arm is volume small end, and clamping force is delivered to left and right part by upper-lower compacting block 6 by rotary cylinder 5, the upper-lower compacting block 6 of T-type structure, existing base bears clamping force, because its volume is large, intensity is high, and Long-Time Service is also not easily damaged; Upper arm is had again to contact with left and right part, because its face area is little, the force rate of then unit are being born directly uses holds as large with the power during part end contact of left and right greatly, so just while the enough clamping power of guarantee, save the power that rotary cylinder 5 provides, in addition, more the compact heap of small end face area contacts with left and right part, more favourable to its surface quality, more guaranteed.
Below know-why of the present utility model is described in conjunction with specific embodiments.These describe just in order to explain principle of the present utility model, and can not be interpreted as the restriction to the utility model protection domain by any way.Based on explanation herein, those skilled in the art does not need to pay performing creative labour can associate other detailed description of the invention of the present utility model, and these modes all will fall within protection domain of the present utility model.
