A kind of frock for the processing of bobbin carriage dividing plate
The utility model relates to the manufacture field of Tube Sheet of Heat Exchanger separator for container, relates in particular to a kind of frock for the processing of bobbin carriage dividing plate.
In the prior art, as shown in Figure 1 and Figure 2, the structure of large heat exchanger bobbin carriage 1 comprises ellipse head 101, cylindrical shell 102, flange end 103, hanger 104, in its bobbin carriage of large heat exchanger, all be provided with dividing plate 106, mainly be to carry out tube side to divide Cheng Zuoyong, mainly have following problem in the process for large heat exchanger bobbin carriage dividing plate sealing surface:
(1) bobbin carriage dividing plate wooden partition is thinner, is subjected to the impact of lathe tool circumference cutting force in the Vehicle Processing process, if the lathe tool depth of cut is slightly large, permanent realization can appear in dividing plate, causes using and to affect sealing effectiveness; Instantaneous elastic deformation can occur and " shake cutter " phenomenon occur in dividing plate in addition, cause that the process tool edge bursts apart, crackle appears in the dividing plate sealing surface, operating personnel need frequent dismounting lathe tool to carry out grinding, tool setting, have greatly increased process time, affect processing progress; The allowance of dividing plate is 6mm simultaneously, and the depth of cut of lathe tool greatly reduces production and processing efficient once only with 2mm.
(2) because a large amount of intervals that distribute on the dividing plate (the actual working (finishing) area of dividing plate account for whole lathe tool through area 2%), when dividing plate contacts lathe tool at every turn, dividing plate can be subject to the impulsive force of lathe tool, so the lathe tool rotating speed can't be too fast, otherwise easily produces the situation that collapses cutter or dividing plate distortion.Therefore rotating speed and the amount of feeding coefficient of vertical lathe are lower, are generally 12～18 rpms, can't bring into play the advantage of the high cutting output of large-scale vertical lathe, the waste resource.
(3) in order to remedy the situation that the above-mentioned depth of cut is little, rotating speed is low, prior art is welded supplemental support at dividing plate often between dividing plate, in order to increase the rigidity of dividing plate, but after completion of processing, need to carry out repair welding, polishing solder joint in order to remove supplemental support, seeking the rebound of material of the same race and wlding carries out transition and welds above-mentioned supplemental support, affected presentation quality and the strength character of product, whole course of work complexity is loaded down with trivial details, and product quality can't guarantee.
The utility model content
The applicant is for the above-mentioned existing slow-speed of revolution, low feeding, and depth of cut conference produces the problems such as dividing plate distortion, shake cutter, a kind of frock for the processing of bobbin carriage dividing plate is provided, have advantages of simple in structure, easy for installation, greatly improve machining accuracy by the utility model, reduced production cost.
The technical scheme that the utility model adopts is as follows:
A kind of frock for the processing of bobbin carriage dividing plate comprises base plate, has installing hole on the base plate, and base plate is connected with fixed head is vertical, has groove on the fixed head, is provided with reinforcement between base plate and fixed head.
Its further technical scheme is:
Have circular hole on the described reinforcement;
Groove on the described fixed head is dovetail groove.
The beneficial effects of the utility model are as follows:
(1) the utility model is simple in structure, easy for installation, utilizes supporting mechanism that bobbin carriage is calibrated, and calibration speed is fast, and precision is high.Utilize hold-down mechanism that bobbin carriage is implemented thrust, make bobbin carriage fixed on workbench, guaranteed the install rigidity of bobbin carriage, effectively avoided the vibrations of cutter in the process, avoided between dividing plate, to weld aiding support and the problem that increases rigidity in the past.
(2) greatly shorten process time, only need successively roughing and a fine finishining can finish the processing of bobbin carriage dividing plate sealing surface after utilizing the utility model, make lathe can give play to maximum cutting speed.

The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described.
Such as Fig. 4, shown in Figure 5, the base plate 4-3 that comprises described in the utility model, have installing hole 4-6 on the base plate, base plate 4-3 is connected with fixed head 4-1 is vertical, have groove 4-4 on the fixed head 4-1, as shown in Figure 6, groove 4-4 is dovetail groove, between base plate 4-3 and fixed head 4-1, be provided with reinforcement 4-2, (quantity of circular hole is 5 among Fig. 4 to have circular hole on the reinforcement 4-2, its diameter and quantity are set according to the actual conditions of reinforcement size), its objective is in order to alleviate weight of the present utility model, reach the purpose of economical with materials.
Actual installation process of the present utility model is as follows:
The first step: as shown in Figure 3, bobbin carriage 1 places on the platen 6, the back side of the utility model fixed head 4-1 and channel flange 103 is fitted tightly, as shown in Figure 7, owing to having two threaded mounting holes 107 on the channel flange 103, utilize first this securing member of securing member 3(for existing known configurations, generally formed by set bolt and nut), fixed head 4-1 is connected with channel flange 103.
Second step: as shown in Figure 3, owing to have a plurality of dovetail grooves on the platen 6, the threaded mounting hole 4-6 on the base plate 4-3 is corresponding with the dovetail groove of above-mentioned platen 6, by the second securing member 7 base plate and workbench are fixed; Then hold-down mechanism is executed thrust to channel flange 103, makes bobbin carriage fixed on workbench, has guaranteed the install rigidity of bobbin carriage, has effectively avoided the vibrations of cutter in the process.
The 3rd step: as shown in Figure 3, be positioned on the platen 6, in the two ends, bottom of cylindrical shell 102, supporting mechanism is installed, as shown in Figure 8, supporting mechanism comprises gripper shoe 5-3, gripper shoe 5-3 is welded in respectively the two ends of brace summer 5-2, has installing hole and the symmetrical double-screw bolt 5-2 that installs at brace summer 5-2, locks by nut 5-6, weld at last arc gripper shoe 5-1 between double-screw bolt 5-2, the radian of arc gripper shoe 5-1 is consistent with the radian of cylindrical shell 2.
After above-mentioned steps is finished, can process bobbin carriage dividing plate sealing surface.
The utility model is simple in structure, easy for installation, utilizes supporting mechanism that bobbin carriage is calibrated, and calibration speed is fast, and precision is high.Utilize hold-down mechanism that bobbin carriage is implemented thrust, make bobbin carriage fixed on workbench, guaranteed the install rigidity of bobbin carriage, effectively avoided the vibrations of cutter in the process, avoided between dividing plate, to weld aiding support and the problem that increases rigidity in the past.
Greatly shorten process time, only needs successively roughing and a fine finishining can finish the processing of bobbin carriage dividing plate sealing surface after utilizing the utility model, makes lathe can give play to maximum cutting speed.
The structure of above-mentioned hold-down mechanism is existing known technology, and hold-down mechanism comprises pad, pressing plate, supporting member, spiral and nut;
