Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment the present invention will be further described.
As shown in Figure 1, a kind of work holder being applied on horizontal lathe, including the support baseboard 2 being arranged on lathe bed surface 1, bearing plate is provided with two packaged type brackets 3, and bracket 3 is provided with support roller 4 free to rotate.Bracket 3 can horizontally slip on bed surface 1, and can be locked with bed surface by bolt.
As shown in Figure 1, when left and right bracket 3 moves to correct position, workpiece can be held up by the support roller 4 on bracket 3 by bottom workpiece 5.As shown in Figure 1, clamping device described in the present embodiment clamps mainly for thin-wall circular tubbiness workpiece, according to explained below, utilizes this clamping device that other shapes of workpiece can be formed stable holding equally.
As shown in Figure 1, bearing plate 2 is additionally provided with portal frame 6, portal frame vertical plates on both sides 6-1 is positioned on the plate face at support baseboard 2 two ends, portal frame 6 can move left and right adjustment so that the centrage of portal frame and the axis of workpiece is vertical coincide, simultaneously the bottom of portal frame riser 6-1 can and bearing plate 2 between fastened by bolt lock.Fixed structure can use and arrange chute on the bottom fixed board of portal frame riser 6-1, and bolt is through the mode of chute with bearing plate locking.This fixed form is relatively conventional in adjustment type fixed structure, does not the most illustrate this structure.
As shown in Figure 1, being respectively provided on two sides with adjustable roller device 7 at portal frame 6 top center line, roller devices is provided with roller 7-1 free to rotate.
As shown in Figure 1, two support rollers 4 of bottom and the two roller 7-1 at top form clamp position to workpiece, it is ensured that workpiece is in steady statue in the course of processing.
Adjust portal frame 6 for convenience of left and right and make that the centrage of portal frame is vertical with the axis of workpiece to coincide, as shown in Figure 1, be provided with side ejection device 8 in the side of bearing plate.Shown in accompanying drawing 2, this side ejection device 8 includes the side jacking nut 8-1 being fixed on bearing plate 2 side, the end of side top fastening bolt 8-2 offsets through the portal frame riser 6-1 of side jacking nut 8-1 with this side of gripper shoe, portal frame can be promoted to be moved to opposite side by rotating side top fastening bolt 8-2.
The side ejection device 8 of side shown in accompanying drawing 1, during actual fabrication, can be respectively provided with side ejection device to facilitate the left and right of portal frame to adjust in portal frame both sides.
Shown in accompanying drawing 1, when processing the workpiece of different-diameter, as a example by accompanying drawing 1, the diameter of workpiece diminishes, two support rollers 4 bottom workpiece should be close to each other, and the roller 7-1 at workpiece top should be the most close to touch surface of the work to workpiece along workpiece.Can horizontally slip owing to installing the bracket 3 of support roller 4, therefore two support rollers 4 near or separate and be easily achieved, roller 7-1 then needs to arrange special structure along workpiece movement radially and is achieved.
In the present embodiment, roller 7-1 is to use having structure to realize in workpiece movement in the radial direction.
As shown in Figure 3, adjustable roller device 7 includes an inverted L shape right angle flap 7-2, right angle flap long slab body 7-2-1 is fixing with the laminating of portal frame 6 surface, right angle flap short slab body 7-2-2 stretches out outside portal frame, it is provided with a slide body 7-3 below right angle flap short slab body 7-2-2, slide body 7-3 be arranged in parallel with right angle flap long slab body 7-2-1, the one end adjusting screw rod 7-4 through right angle flap short slab body 7-2-2 and extends to inside slide body along slide body axis, adjust threaded engagement between screw rod 7-4 and slide body 7-3, adjust and fixed by bearing between screw rod 7-4 and right angle flap short slab body 7-2-2.As shown in Figure 3, being provided with roller supporting axle 7-1-1 bottom slide body, one end of roller supporting axle 7-1-1 is radially fixed with slide body 7-3, and the other end of roller supporting axle stretches out slide body and installs roller 7-1 at this end.As shown in Figure 3, when positive and negative rotation adjusts screw rod 7-4, slide body 7-3 can move up and down, and understands in conjunction with accompanying drawing 1, when slide body 7-3 moves up and down, slide body 7-3 drives roller 7-1 radially to move along workpiece thus ensures that roller 7-1 is pressed in the surface of workpiece 5 all the time.
As shown in Figure 1, when processing thin-walled drum part endoporus, support roller 4 and roller 7-1 is fixing on excircle of workpiece circumferencial direction, owing to during excircle of workpiece majority, cylindricity and roughness requirements are the highest, for cylindricity and roughness requirements after hole machined in ensureing, as shown in Figure 3, self-aligning bearing 7-1-2 is used to be fixed between roller 7-1 and roller supporting axle 7-1-1.According to this structure, the fixing same of the support roller 4 on movable carriage 3 uses self-aligning bearing 7-1-2 to fix, and so support roller 4 and roller 7-1 can realize being automatically adjusted according to the practical situation of excircle of workpiece, ensures that inner hole of workpiece center reference is constant with this.
For ensureing that the position that roller 7-1 is radially adjusted in place rear slider body 7-3 at workpiece is fixed, in this adjustable roller device 7, it is provided with locking device.Concrete structure is as shown in Figure 4, the cross section of slide body 7-3 is in " convex " font, slide body 7-3 away from the surface of flap long slab body side, right angle with left and right step, two latch segment 7-7 lay respectively on the step of left and right, the width of latch segment 7-7 is more than step width, latch segment 7-7 is provided with locking pull bar 7-5, locking pull bar 7-5 and passes portal frame 6 and right angle flap long slab body 7-2-1, and is provided with tightening nut 7-6 in locking pull bar 7-5 outer end.
Understand shown in 4 with reference to the accompanying drawings, when, after locking pull bar 7-5 tension, " asphyxia by external pressure on the chest and abdomen " between slide body 7-3 and portal frame 6, latch segment 7-7 are equivalent to brake shoes by the left and right step of slide body 7-3 by latch segment 7-7, and now slide body 7-3 cannot move up and down.After unclamping locking pull bar 7-5, forming space between the left and right step of latch segment 7-7 and slide body 7-3, slide body 7-3 can move up and down.
Adjust this clamping device clip position on workpiece for convenience, this clamping device also includes tandem motion, and as shown in Figure 1, this mechanism includes the tooth bar 9 that lathe bed surface is disposed axially below, tooth bar is positioned at the axial groove 10 of lathe bed surface, and the adjustment gear 11 engaged with tooth bar.As shown in Figure 5, adjust gear 11 and be connected with bearing plate 2 formation through the swingle set 13 on front side of support baseboard 2 with swingle 12, swingle 12, make bearing plate along tooth bar 9 axially-movable front and back shown in accompanying drawing 1 by positive and negative rotation swingle 12.
