Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

Referring to fig. 1-3, a centre gripping accessory that gearbox gear production and processing used, including support frame 1 and gear 4, support frame 1 is "L" shape block structure, the lateral wall welding of support frame 1 has locating piece 2, the one end welding that support frame 1 was kept away from to locating piece 2 has dabber 3, the lateral wall of dabber 3 runs through and has seted up turn trough 8, the inner wall threaded connection of turn trough 8 has pivot 5, the circumference lateral wall threaded connection of pivot 5 has commentaries on classics board 6, the one end welding that commentaries on classics board 6 is close to gear 4 has compressing cylinder 7, gear 4 cup joints on dabber 3, the inside of dabber 3 is equipped with the ejection mechanism who is used for strengthening gear. The ejection mechanism comprises a plurality of ejector blocks 10, the outer wall of the mandrel 3 is provided with a plurality of sliding grooves 9 communicated with the rotating groove 8, the ejector blocks 10 correspond to the sliding grooves 9 one by one, and each ejector block 10 is connected with the inner wall of the corresponding sliding groove 9 in a sliding mode.

The side wall of each top block 10 is provided with a top groove 11, the inner wall of each sliding groove 9 is welded with a limiting rod 12, and the limiting rods 12 correspond to the top grooves 11 one by one; every gag lever post 12 all with the inner wall sliding connection who corresponds the overhead tank 11, the lateral wall of every gag lever post 12 all has spacing spring 13 with overhead tank 11 is close to the common welding of one side inner wall of rotary tank 8, through spacing spring 13's limiting displacement for inside the kicking block is in spout 9 under not receiving the exogenic action, guarantees that the cover that gear 4 can be smooth establishes on 3 outer walls of dabber, makes things convenient for gear 4's installation.

Every kicking block 10 is close to the one end of turn trough 8 and is the inclined plane to the one end that is close to locating piece 2 is close to turn trough 8 more, makes pivot 5 can promote kicking block 10 to the inside in-process that removes of turn trough 8 and remove to spout 9 outsides, and then realizes the accurate location to gear 4 with the contact of gear 4, guarantees

gear

4 and 3 same axle centers of dabber, and the one end that pivot 5 is close to gear 4 is the taper shape, guarantees to promote the kicking block 10 that the slope set up.

The circumference lateral wall cover of dabber 3 is equipped with paster 14, and paster 14 uses elastic rubber material to make, and paster 14 makes the contact of clamping cylinder 7 and gear 4 inseparabler through deformation to can avoid clamping cylinder 7 and gear 4's direct contact, avoid clamping cylinder 7 to cause wearing and tearing to the gear 4 surface.

When the gear needs to be machined, firstly, the rotating shaft 5 is rotated to be separated from the rotating groove 8, so that the rotating plate 6 does not obstruct the positioning and installation of the gear 4, then the gear 4 is sleeved on the mandrel 3 to realize the pre-positioning of the gear 4, meanwhile, the patch 14 is sleeved on the mandrel 3 and is attached to the gear 4, then the rotating shaft 5 is aligned with the rotating groove 8 and rotates inwards, when the rotating shaft 5 moves towards the inside of the rotating groove 8 and gradually contacts the top block 10, the front end of the rotating shaft 5 pushes one end of the top block 10 far away from the rotating groove 8 to slide, so that the top block 10 gradually moves out of the sliding groove 9 and gradually contacts with the gear 4, so that the interval between the gear 4 and the mandrel 3 is supplemented by the top block 10, the gaps of the gear 4 and the mandrel 3 at all positions are equal, further the coaxial centers of the gear 4 and the mandrel 3 are kept, further the machining precision of the gear 4 is ensured, and the same mandrel 3 can be used for machining, the device has more universal performance;

and then the position of the rotating shaft 5 is kept, the rotating plate 6 on the rotating shaft is rotated to move towards the gear 4, the pressing cylinder 7 is enabled to continuously approach the gear 4 until the pressing cylinder 7 is contacted with the patch 14 and deforms, and the gear 4 is further pushed to move towards the direction of the positioning block 2 and abut against the side wall of the positioning block 2, so that the gear 4 is fully clamped and positioned.
