Description

Vertical lathe is processed big-and-middle-sized shaft coupling taper hole device

Technical field

The utility model relates to a kind of processing unit (plant), particularly relate to a kind of on common vertical lathe in, large-scale shaft coupling tapered post pin-and-hole processing unit (plant).

Background technology

For the shaft coupling that taper hole is arranged, the traditional handicraft method is: press the taper hole path with line or drill jig and bore straight hole, expand the hinge taper hole with taper reamer again and be shaped.The shortcoming of traditional handicraft method is: 1, the error of division is big, and the line error of division reaches 0.5mm, and the drill jig error of division reaches 0.2mm, and the boring actual error is owing to bore the skew of flower chisel edge, and the error of division is more greater than above-mentioned value.2, steel part taper hole fraising, expensive outsourcing high-speed steel taper reamer damages especially severe, and one can only process 2～3 shaft couplings to reamer.3, high-speed steel taper reamer small end cutting frequency is higher than big end, and head and the tail hole taper hole angle value instability, deviation reach 10 '～20 '.4, expand hinge taper hole, inefficiency with taper reamer.5, during hinge steel part hole because of can not the machine feed, can only ream by hand, labour intensity is especially big.

The utility model content

Technical problem to be solved in the utility model provides a kind of high accuracy quality, low-cost consumption, and simple in structure, economical and practical vertical lathe is processed big-and-middle-sized shaft coupling taper hole device.

For solving the problems of the technologies described above, the vertical lathe that the utility model provides is processed big-and-middle-sized shaft coupling taper hole device, comprise vertical lathe disk workbench, rotary table and vertical lathe ram, it is corresponding with described vertical lathe ram that described rotary table is installed in described vertical lathe disk workbench one side, described vertical lathe disk workbench opposite side is equipped with balancing weight, and described rotary table is equipped with location tire plate and bolt and the nut corresponding with shaft coupling to be processed.

Described rotary table is 1: 90 worm gear pair.

Adopt the vertical lathe machining large shaft coupling taper hole device of technique scheme, hole size coupling in location tire plate and the shaft coupling, the weight-matched of balancing weight and rotary table, location tire plate and shaft coupling compared with prior art, has following advantage:

1, production efficiency height.Owing to be turning process, the amount of feeding and feeding depth, feed all can substantially exceed ream, and work efficiency improves 3～5 times;

2, indexing accuracy height.Owing to be the high worm gear calibration of precision, the error of division can be controlled in≤0.05mm, is 1/5～1/8 of the line or the drill jig error of division.

3, the cutter loss is low.With the high-speed steel taper reamer of costliness, can cut with scissors cast iron shaft coupling 80 holes～100 holes, can cut with scissors cast steel shaft coupling 10 holes～20 holes, and make turning into this device, it only is 1/100 that the blade loss is worth.

4, labour intensity is low.Cut with scissors taper hole with conventional method, especially cut with scissors the cast steel taper hole, feeding by hand, labour intensity is especially big, and installs turning with this, available machine feed feeding, labour intensity reduces greatly.

In sum, the utility model device is high-quality, efficient, low consumption, low labour intensity, can extensively be used in the shaft coupling especially processing of cast steel shaft coupling tapered post pin-and-hole and the processing of similar products, has very strong practicality and generalization.

Description of drawings

Accompanying drawing is the utility model device schematic diagram.

The specific embodiment

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

Referring to accompanying drawing, it is corresponding with vertical lathe ram 11 that rotary table 1 is installed in vertical lathe disk workbench 7 one sides, and vertical lathe disk workbench 7 opposite sides are equipped with balancing weight 5.Rotary table 1 is equipped with location tire plate 2 and bolt 3 and the nut 4 corresponding with shaft coupling to be processed 6, and rotary table 1 is 1: 90 worm gear pair.Location tire plate 2 and shaft coupling 6 interior hole size couplings, the weight-matched of balancing weight 5 and rotary table 1, location tire plate 2 and shaft coupling 6.

Referring to accompanying drawing, select and bored or cast the location tire plate 2 of the shaft coupling 6 endoporus coupling of gross porosity, shaft coupling 6 location and installation on location tire plate 2, are crossed axis hole clamping bolt 3 and nut 4, and fastened.Rotary table 1 together with mounted shaft coupling 6, together is placed on the C5116 vertical lathe disk workbench 7.

Lay centering as follows: the hole centre-to-centre spacing index line 9 that marks shaft coupling 6 taper holes 8 according to drawing earlier, driving scriber centering, and the position of adjustment rotary table 1, the hole centre-to-centre spacing index line 9 of shaft coupling 6 taper holes is overlapped with the centre of gyration 10 of C5116 vertical lathe.Bulk article only needs the initial workpiece centering.

Position and weight-matched balancing weight 5 according to rotary table 1, location tire plate 2 and shaft coupling 6.

With the shaft coupling 6 of processing 10 1: 10 taper holes 8 is example: lay the good rotary table 1 of centering, location tire plate 2, shaft coupling 6 and balancing weight 5." oblique angle is pulled tiltedly, installs length and digs cutter greater than the long endoporus of taper hole, goes out 1: 10 taper hole 8 of shaft coupling on the basis of boring or having cast gross porosity by figure paper size car by 2 ° 51 ' 45 with C5116 vertical lathe ram 11.Behind 1 taper hole 8 of car, rotate rotary table 1 and rotate 36 ° of next taper holes 8 of processing, repeat process step finishes until all taper hole 8 Vehicle Processings successively.
