The specific embodiment
The invention discloses a kind of anchor clamps and have the end face milling drill centers lathe of these anchor clamps,, improve surface roughness to reduce the end face run-out of part to be processed.
To combine the accompanying drawing in the embodiment of the invention below, the technical scheme in the embodiment of the invention is carried out clear, intactly description, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the present invention's protection.
See also Fig. 1-Fig. 3, the end face milling drill centers lathe that Fig. 1 provides for the embodiment of the invention is with the structural representation of anchor clamps; The end face milling drill centers lathe that Fig. 2 provides for the embodiment of the invention is with the partial side TV structure sketch map of anchor clamps; Fig. 3 is the cutaway view of Fig. 2 along the A-A line.
End face milling drill centers lathe provided by the invention is used anchor clamps; Comprise the base plate 8 on the horizontal slide unit that is arranged at end face milling drill centers lathe and be arranged at the base 26 on the base plate 8; Wherein, Also comprise two chuck body that are arranged at base 26 both sides respectively, the two ends that two chuck body are respectively applied for workpiece clamp.
Chuck body comprises retractor device, power transmission shaft 27, gear 28, left grip slipper, right grip slipper and cramping body 2.Wherein, retractor device is arranged at an end of base 26, the clamping that can realize anchor clamps with withdrawal through stretching out of its extension bar with unclamp.Power transmission shaft 27 is arranged in the base 26, and is slidingly matched with base 26, and an end of power transmission shaft 27 links to each other with the extension bar of retractor device, and the other end axially offers the gear teeth along it.
Gear 28 rotating being arranged in the base 26, and be positioned at the upside of power transmission shaft 27, this gear 28 is meshed with the gear teeth on the power transmission shaft 27, and gear 28 is middle drive disk assembly, is used for converting power transmission shaft 27 mobile into tooth bar 30 moving round about.Gear 28 can be installed in the base 26 through needle bearing 39, to realize the rotation of gear 28.
Left side grip slipper and right grip slipper slidably are arranged on the base 26, and power transmission shaft 27 is provided with the contiguous block 17 that links to each other with left grip slipper, and right grip slipper is provided with the tooth bar 30 that is meshed with gear 28.Tooth bar 30 can drive right grip slipper and move, and power transmission shaft 27 can drive left grip slipper and move.Because the present invention need distinguish the two ends of clamping work pieces; Therefore it has two chuck body; Have two left grip slippers and right grip slipper on two chuck body respectively; As shown in Figure 1, left front grip slipper 3, the right front grip slipper 9 corresponding, left back grip slipper 4 and the right back grip slipper 10 corresponding with left back grip slipper 4 with left front grip slipper 3.For the ease of describing, this case is only described with one of them chuck body.
Cramping body 2 is arranged at respectively on left grip slipper and the right grip slipper, promptly be provided with on each grip slipper cramping body 2 on the grip slipper of 2, two positioned opposite of cramping body be used for realizing through relatively moving to the clamping of workpiece with unclamp.
End face milling drill centers lathe provided by the invention is used anchor clamps, and the extension bar through retractor device stretches out and drives power transmission shaft 27 and move forward, and the contiguous block on the power transmission shaft 27 drives left grip slipper and follows to equidirectional and move.In the process that power transmission shaft 27 moves forward; The gear teeth of one of which end and gear 28 engagements; And driven wheel 28 rotations, gear 28 drives tooth bar 30 levels and oppositely moves in rotating process; Because tooth bar 30 and power transmission shaft 27 lay respectively at the both sides of gear 28, so the moving direction of tooth bar 30 and power transmission shaft 27 is opposite.Tooth bar 30 promptly moves to the rightabout that power transmission shaft 27 moves, and drives right grip slipper and move, and promptly right grip slipper and left grip slipper move in opposite directions, changes it on the realization of the spacing between the cramping body 2 to the clamping of workpiece.Extension bar withdrawal through retractor device can realize unclamping workpiece.Two chuck body are carried out clamping to the two ends axle journal of workpiece respectively.
The present invention has only designed anchor clamps again at the hydraulic pressure yarn of lathe system, electric yarn system, under the situation that laterally slide unit etc. is constant.Compact conformation of the present invention, good rigidly, clamping limb are lacked, clamping force is big, vibration is little, and mobilizable in addition grip block can clamp with the casting surface irregular conditions of part to be processed constantly.Part end face after the processing is beated little, in 0.1 millimeter, surface roughness about Ra3.2, the central hole size high conformity, qualified fully, guaranteed product quality.After adopting the present invention, output has promoted about 2 times of production capacities at 800~1000.
Cramping body 2 can be articulated in respectively on left grip slipper and the right grip slipper through turning cylinder 1.Because cramping body 2 can be articulated on the grip slipper respectively through turning cylinder 1, so it can rotate along this turning cylinder 1.Cramping body 2 on the left and right grip slipper can rotate within the specific limits, to adapt to the clamping of workpiece.Be respectively equipped with the lock screw 14 that offsets with turning cylinder 1 on left side grip slipper and the right grip slipper, can cramping body 2 be locked on the certain angle through this lock screw 14.
Cramping body 2 is provided with several grip blocks 13, and the front end face of grip block 13 is the clamping face that contacts with workpiece to be processed.In the present embodiment, each cramping body 2 is provided with between the clamping face of 13, two grip blocks 13 of two grip blocks has certain angle, to improve the contact area with workpiece.
Contiguous block 17 is sheathed on the power transmission shaft 27, and through being arranged at assembly cap 25 axial location on the power transmission shaft 27.Be respectively equipped with the locating piece 15 of workpiece to be processed axial location on left side grip slipper and the right grip slipper.Tooth bar 30 is fixed on the base 26 through sunk screw 31.Retractor device can be oil cylinder, and the piston rod of oil cylinder links to each other with power transmission shaft 27.
Oil cylinder can specifically comprise cylinder body 21, cylinder cover 18, oil cylinder connecting plate 24 and piston 19.Wherein, cylinder body 21 is provided with pipe joint 22, and pipe joint 22 is two, is used for feeding in the phase cylinder body 21 hydraulic oil and comes moving forward and backward of driven plunger.Cylinder cover 18 is arranged at an end of cylinder body 21, and oil cylinder connecting plate 24 is arranged at the other end of cylinder body 21, and piston 19 is arranged in the cylinder body 21, and piston rod one end of this piston 19 is stretched out by oil cylinder connecting plate 24, and oil cylinder connecting plate 24 links to each other with base 26.
End face milling drill centers lathe provided by the invention, comprise horizontal slide unit be provided with horizontal slide unit on anchor clamps, wherein, anchor clamps are as above disclosed anchor clamps of embodiment.Therefore end face milling drill centers lathe provided by the invention possesses all technique effects of above-mentioned anchor clamps equally owing to adopt the disclosed anchor clamps of the foregoing description, and this case is repeated no more.
Each embodiment adopts the mode of going forward one by one to describe in this specification, and what each embodiment stressed all is and the difference of other embodiment that identical similar part is mutually referring to getting final product between each embodiment.
