Abstract
The utility model relates to an eccentric clamping device of two claws mainly comprises chuck, balancing piece, jack catch group, locating plate, fastening screw. Chuck A disc -shaped structure sets up the below at whole anchor clamps. The balancing piece passes through the bolt fastening and in the chuck upper end, sets up with the locating plate symmetry. The locating plate setting in jack catch group one side relevant position. Jack catch group symmetry sets up in the chuck top, between balancing piece and the locating plate. Fastening screw group sets up in jack catch upper end chucking position. The utility model discloses eccentric clamping device of two claws adopts box chuck standard machine tool accessory, and its commonality is good, and the adjustment is convenient, and centering precision is high, leads to the processing that is applicable to 90 degree similar elbow fitting. Product processingquality is reliable, and production efficiency improves greatly.
Description
Technical field
The utility model belongs to mechanical device field, is specifically related to fast aligning right angle tubulose Central of the parts on a kind of energy lathe, thus improves the clamping device of crudy.
Background technology
In aviation hydraulic system, there is a lot of right angle tubular members, because its center carpenters square cun requires higher, adopt conventional workpiece machining clamp often can not meet the demands, modal fixture then adopts changes terminal pad on lathe spindle and scroll chuck, again make floral disc, after floral disc is connected with main shaft, then the vehicle clamper designed in addition is contained on floral disc by interference fit and bolted pattern.The shortcoming of the program is: 1, fabrication cycle is long.2, repeatedly dismantle, spindle coupling disc is installed, the dimensional accuracy of main shaft and terminal pad can be reduced, affect the machining accuracy of follow-up conventional axial workpiece.3, because lathe model is different, the interface pattern of main shaft and terminal pad and size can be different, cause the physical dimension of floral disc and pattern also can be different.Therefore, how to overcome the shortcoming that above fixture exists, realize fast aligning part machining center on lathe, and be connected on lathe soon by conventional connected mode, thus enhance productivity, this is that union elbow produces the difficult problem that must first solve.
Utility model content
The technical problem that the utility model mainly solves be to provide one can on lathe fast aligning right angle tubulose Central of the parts, and the fixture on lathe can be connected to fast, thus improve the clamping device of crudy and production efficiency.
A kind of two pawl eccentric clamping devices, primarily of chuck, balance weight, dog group, location-plate, trip bolt group composition.Chuck structure in the form of annular discs, is arranged on the bottom of whole fixture.Balance weight is bolted on chuck upper end, is symmetrical arranged with location-plate.Described location-plate is arranged on relevant position, dog group side.Dog group is made up of 2 claws, is symmetricly set on above chuck, between balance weight and location-plate.Trip bolt group is made up of 2 screws, is separately positioned on clamping position, each claw upper end, mainly plays the role of fastening.
The utility model two pawl eccentric clamping device, adopt two-jaw(ed)chuck standard machine tool annex, its versatility is good, easy to adjust, and centering precision is high, the logical processing being applicable to similar 90 degree of union elbows.Product processing quality is reliable, and production efficiency improves greatly.
Accompanying drawing explanation
Fig. 1 is the front view of the utility model two pawl eccentric clamping device;
Fig. 2 is the top view of the utility model two pawl eccentric clamping device;
Fig. 3 is the left view of the utility model two pawl eccentric clamping device.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
One two pawl eccentric clamping device as shown in Figure 1, Figure 2, Figure 3 shows, forms primarily of chuck 1, balance weight 2, dog group 3, location-plate 4, trip bolt group 5.Chuck 1 structure in the form of annular discs, is arranged on the bottom of whole fixture.Balance weight 2 is bolted on chuck 1 upper end, is symmetrical arranged with location-plate 4.Described location-plate 4 is arranged on relevant position, dog group 3 side.Dog group 3 is made up of 2 claws, is symmetricly set on above chuck 1, between balance weight 2 and location-plate 4.Trip bolt group 5 is made up of 2 screws, is separately positioned on clamping position, each claw upper end, mainly plays the role of fastening.
The utility model main body adopts Machine Tool Standard annex and two-jaw(ed)chuck, realizes fixture and is connected with the reliable of lathe, by the redesign to clamping part dog group 3, make the distance that position, clamping section off center is certain, makes it to realize clamping to right angle class pipe joint.By location-plate 4, regulate location end face to the pivot distance of chuck 1, the centre-to-centre spacing that can realize part two terminations controls in the dimensional requirement of regulation.
In order to ensure the reliability of this fixture, to the raw material of vital part in device and the property indices that will reach, all make concrete requirement.Be mainly:
1, dog group 3 adopts 45#, and heat treatment reaches 36-40HRC;
2, location-plate 5 adopts 45#, and heat treatment reaches 36-40HRC;
During use, the part other end is put into the semicircle groove at two eccentric two pawl clamping positions, four square head wrenches are inserted in chuck, rotates clockwise spanner, drive chuck radial contraction, realize clamping.When need take off part, be then rotated counterclockwise spanner, chuck outwards opens, and realizes unclamping part.
The advantage of the utility model two pawl eccentric clamping device:
1, adopt two-jaw(ed)chuck standard machine tool annex, its versatility is good, easy to adjust, and centering precision is high, the logical processing being applicable to similar 90 degree of union elbows;
2, product processing quality is reliable, and production efficiency improves greatly.
