Abstract
The utility model provides a workpiece clamping structure of a constant-speed universal-joint inner sphere surface grinding machine, comprising a driving device and a clamping device, wherein the driving device comprises a rotating cylinder and a sleeve main shaft which are arranged on a belt wheel; a screw rod is connected with a piston rod of the rotating cylinder; a connecting rod in the clamping device is connected on the screw rod, and the end surface of the connecting rod is arranged on the shell in a supporting manner; and the shell is fixedly arranged at the front end of the sleeve main shaft. The workpiece clamping structure is characterized in that the clamping device also comprises an elastic conical sleeve and a gear ring; the gear ring is fixedly connected with the connecting rod; a claw body structure at the rear end of the elastic conical sleeve is matched with the gear ring to form clamping connection; and the inner surface of the shell is a conical surface and is tightly attached to the elastic conical sleeve. In the workpiece clamping structure, the inner surface of the shell, which is the conical surface, is attached to the elastic conical sleeve in a cone-body shape, the clamping force generated by the elastic conical sleeve is uniform and linear, and then the positioning end surface of a workpiece is reliably and stably arranged on the end surface support in a pressing manner, so that the clamping and grinding process of the workpiece is stable and reliable.
Description
Technical field
The utility model relates to the technical field of grinding machine clamping part, is specially a kind of constant velocity cardan joint Internal Spherical Surface grinding machine workpiece clamp locking structure.
Background technology
Existing universal joint Internal Spherical Surface grinding machine workpiece clamp locking structure is seen Fig. 1, belt pulley 2 drives main shaft 3 revolutions by flat key, housing 10 is contained in the front end of main shaft 3, spring leaf 9 is contained on the housing 10, adjusting seat 8 is fixed on the spring leaf 9, claw 7(six lobes) can on adjustment seat 8, make radiai adjustment, angling cylinder 1 is contained on the belt pulley 2 with main shaft 3 revolutions, piston at rotating while oil cylinder can move axially under hydraulic action, when moving, piston forward drives push rod 5 jack-up spring leafs 9 by screw rod 4, make claw 7(six lobes) thus radially micro-moving unclamped workpiece, and when piston is mobile backward, drive push rod 5 trip spring sheets 9 by screw rod 4, and make claw 7(six lobes) radially micro-mobile clamping work pieces under the active force of spring leaf recovery deformation.Because the material and heat treated influence that are subjected to spring leaf, the clamping force size that the spring leaf distortion is produced is uneven, add that the clamping force that the spring leaf distortion is produced is not linear, this just makes that to cross the clamping force that distortion is produced when thin at spring leaf not enough, and deformation force makes oil cylinder be difficult to back down spring leaf too greatly when blocked up, influences the normal clamping of workpiece and the stability of grinding.In addition,, need claw 7(six lobes because the clamping external diameter of different workpieces is different) make radiai adjustment one by one adjusting on the seat 8, the location could normal clamping workpiece after with one heart, and this just makes that time and difficulty of changing frock increase greatly.
Summary of the invention
At the problems referred to above, the utility model provides a kind of constant velocity cardan joint Internal Spherical Surface grinding machine workpiece clamp locking structure, and clamping force evenly and be linear makes clamping workpiece and grinding reliable and stable.
Its technical scheme is such: a kind of constant velocity cardan joint Internal Spherical Surface grinding machine workpiece clamp locking structure, it comprises drive unit, clamping device, described drive unit comprises the angling cylinder angling cylinder, quill spindle, described quill spindle, angling cylinder is installed on the belt pulley, screw rod is connected on the piston rod of described angling cylinder, connecting rod in the described clamping device is connected on the described screw rod, end surface supporting is installed on the housing, described housing is fixedly mounted on described quill spindle front end, it is characterized in that: described clamping device also comprises elastic conical drogue, gear ring, described gear ring is fixedlyed connected with described connecting rod, the corpus unguis structure of described elastic conical drogue rear end cooperates the formation engagement connection with gear ring, described shell inner surface is the conical surface and is adjacent to described elastic conical drogue.
It is further characterized in that: the corpus unguis structure of described elastic conical drogue rear end is the three-jaw body structure.
In the said structure of the present utility model, owing to adopted the shell inner surface that is the conical surface to be adjacent to be the elastic conical drogue of cone, the clamping force that elastic conical drogue produces is even and be linear, make workpiece location end face reliably, stably be pressed on the end surface supporting, thereby make clamping workpiece and grinding process reliable and stable.

The specific embodiment
See Fig. 2, the utility model constant velocity cardan joint Internal Spherical Surface grinding machine workpiece clamp locking structure, comprise angling cylinder 1, belt pulley 2, main shaft 3 is rotated by the angling cylinder 1 that drives main shaft 3 and be loaded on the belt pulley 2 together synchronously by belt pulley 2, housing 9 is contained in the front end of quill spindle 3, the piston rod 10 of angling cylinder 1 is connected with screw rod 4, screw rod 4 is connected with connecting rod 5, gear ring 8 is fixedlyed connected with connecting rod 5 by screw, the rear end of elastic conical drogue 7 is three corpus unguis, after rotating to an angle behind the insertion gear ring 8, just can cooperate and form the engagement connection (see figure 3) with gear ring 8, angling cylinder 1 piston rod 10 front and back trace movements the time drive screw rod 4 trace movements, thereby screw rod 4 drivening rods 5 trace movements drive gear ring 8 trace movements that are connected on the connecting rod 5, and then drive elastic conical drogue 7 front and back trace movement housing 9 in.When elastic conical drogue 7 was mobile backward under angling cylinder 1 effect, the conical surface compressing elastic conical drogue 7 of housing 9 made it produce radially trace contraction, thus clamping work pieces; When elastic conical drogue 7 moves forward under angling cylinder 1 effect, the conical surface of housing 9 unclamp elastic conical drogue 7 make its under the effect of deformation restoring force radially trace open, thereby unclamp workpiece.The utility model has adopted gear ring to drive elastic conical drogue and has moved in housing, thereby inner surface is the housing compressing elastic conical drogue clamping work pieces of the conical surface, the clamping force that elastic conical drogue produces workpiece evenly and be linear, make workpiece location end face reliably, stably be pressed on the end surface supporting, thereby make clamping workpiece and grinding process reliable and stable.
