Description
Technical field
This utility model relates to gear ring fixing tool fixture, particularly relates to inner ring gear interference fit frock clamp。
Background technology
Fixture is to be used for fixing processing object in mechanical processing process, so as to occupy correct position, to accept construction or the device of detection。In a broad sense, any operation in technical process, it is used for rapid, convenient, the safe device installing workpiece, fixture can be become。
The clamp precision of preliminary working can be relatively low, and the positioning precision of high-precision fixture may require that higher。
The patent No. is in the patent documentation of 201410690466.9, disclose one and take turns accurately machined catching plate fixture for this, including clamp head, base determined by the disk that clamp head left end is the cylinder boss that two sides is arranged, right-hand member is for arranging threaded cylindric main shaft, being provided with backing disc on the cylinder boss of right side, the elastic jacket one that main shaft is provided with and elastic jacket two, threaded portion is connected with the nut being lined with mat。
Being pointed out that in above-mentioned patent documentation and be located on the main shaft between elastic jacket one and elastic jacket two by geared sleeve, the rotation then passing through nut carrys out locking gear。In each use procedure, owing to the size of inner ring gear can at certain tolerance passband fluctuation, cause fluctuating within the specific limits in the gap between the inner ring of main shaft and processed gear, if want by adjust central axis and the main shaft coaxial line of gear be impossible, cause process wheel precision low。
Geared sleeve is located on mandrel by existing showing simultaneously, recycles thimble mandrel to be supported, so gear is processed, so also as above, can exist and have gap between inner ring gear and mandrel, cause that the two is difficult to concentrically axis, cause the accuracy of gear processed。
Utility model content
This utility model is intended to provide inner ring gear interference fit frock clamp, to solve inner ring gear that prior art middle gear brings through mandrel and mandrel not concentrically axis, the problem that Gear Processing precision is low。
In base case: inner ring gear interference fit frock clamp, including shaft seat, also include chuck and pull bar, chuck coaxial rotation coaxial with shaft seat connects, circumference on chuck is evenly distributed with three jaws, the inner ring interference fit of the outer circumference surface of three described jaws and processed gear, pull bar push-and-pull chuck hub moves axially along chuck hub, and the jaw side on chuck is provided with locating piece。
For above-mentioned base case, center by pull bar push-and-pull chuck, chuck generation type is made to become, on chuck three claws are closed up, cause the outer circumference surface diameter size less than inner ring gear of three claws, again through locating piece, gear face is axially positioned, work as releasing lever, three claws on chuck restore to the original state, because the outer circumference surface of three jaws is sized larger than the inner ring size of gear, cause interference fit between the inner ring of gear and jaw, this kind is become by type and clamps position limited gear, can guarantee that the central axis conllinear of the gear of processing every time, do not have and have gap between inner ring gear and mandrel and the problem of not coaxial line, if employing scroll chuck, scroll chuck has abrasion in the process of clamping workpiece, and each wear extent difference, cause that the positioning precision of scroll chuck is low, this programme adopt the modification of chuck to carry out gripper simultaneously, positioning precision is high, simultaneously to load and unload the modification amount of gear also less every time for chuck, making chuck reach endurance failure need to through hundreds of thousands time to millions of times, service life is also longer, with low cost。
Preferred version one, based on the further optimization of scheme, jaw by chute can moving radially along chuck, jaw can move radially along chute, adapts to clamp various sizes of Gear Processing, applied widely。
Preferred version two, based on the further optimization of scheme, pull bar is the piston rod of cylinder or hydraulic cylinder, and simple in construction is easy for installation, and reliability is also higher, and also there is Gas fluid pressure station in workshop simultaneously, and power source is also difficult to find。
Preferred version three, based on the further optimization of scheme, locating piece is the multiple pins being threaded on shaft seat through chuck, multiple pins gear is positioned can increase gear and contact point, axial limiting can be more stable。
Preferred version four, based on the further optimization of scheme, shaft seat is outside equipped with containment vessel, and chuck and shaft seat are positioned at containment vessel, and chip more than having in Gear Processing process point splashes, and protects visitor can effectively protect operator, simultaneously。
Accompanying drawing explanation
Fig. 1 is the schematic front view of this utility model embodiment；
Fig. 2 is the schematic front view of this utility model embodiment。
Detailed description of the invention
Below by detailed description of the invention, this utility model is described in further detail:
Accompanying drawing labelling in Figure of description includes: shaft seat 1, chuck 2, jaw 21, pin 22, T-slot 23, connecting hole 24, pin-and-hole 25, piston rod 3。
Embodiment is substantially as shown in Figure 2: on the excircle of chuck 2, outmost turns is evenly distributed with 12 connecting holes 24, on chuck 2, three T-shaped chutes 23 it are evenly distributed with centered by the center of circle of chuck 2, T-shaped chute 23 is fixed on chuck 2 by hexagon socket head cap screw, the T-shaped slide block coordinated with T-slot 23 it is provided with in T-slot 23, T-shaped slide block has and is connected fixing jaw 21 with T-shaped slide block by two hexagon socket head cap screws, between three jaws 21, offer pin-and-hole 25, have push-and-pull hole at the center of chuck 2。
As shown in Figure 1, chuck 2 is threaded on shaft seat 1 by bolt through connecting hole 24, pin 22 is threaded on shaft seat 1 through pin-and-hole 25, piston rod 3 is from left to right through the through hole of shaft seat 1 and outside extending to the push-and-pull hole of chuck 2, and the right-hand end at piston rod 3 is fixedly connected with block。
This utility model is to utilize three jaws 21 and the clamping of inner ring gear interference fit, and the face that three jaws 21 coordinate with inner ring gear has the outline of three jaws 21 to coordinate, and outline is the periphery adapted with inner ring gear。
Under normal condition, the periphery diameter that the outline of three jaws 21 is formed is more than the diameter of inner ring gear to be processed, stretched to the left by piston rod 3, make chuck 2 Inward deflection, after chuck 2 Inward deflection, the diameter dimension of the outline of three jaws 21 reduces, when the diameter of outline of three jaws 21 is less than the diameter of inner ring gear to be processed, the inner ring of gear is nested on three jaws 21, by pin 22, gear is axially positioned, unclamp piston rod 3, chuck 2 recovers prototype, utilize on chuck 2 diameter of three jaws 21 more than the diameter of inner ring gear, make interference fit therebetween, reach the location clamping of gear, simultaneously by adjusting T-shaped slide block, the outline diameter of three jaws can be changed, adapt to the Gear Processing of multiple specification。In order to ensure the service life of chuck 2, the distance that piston rod 3 is moved to the left is also relatively small so that chuck 2 is because of the inefficacy modification of endurance failure, it is necessary to the reciprocal hundreds of thousands time that stretches is to millions of secondary。
Shaft seat 1 extenal fixation has containment vessel, and chuck 2 and shaft seat 1 are covered by containment vessel。
