Specific implementation mode

To make the technical means, creative features, achievement of purpose, and effectiveness of the utility model be easy to understand, below In conjunction with specific implementation mode, the utility model is expanded on further.

In this application unless specifically defined or limited otherwise, term " connection ", " fixation " shall be understood in a broad sense, example Such as, it may be a fixed connection, may be a detachable connection, or is integral；It can be mechanical connection, can also be electrical connection； It can be directly connected, can also can be indirectly connected through an intermediary the connection inside two elements or two elements Interaction relationship.For the ordinary skill in the art, above-mentioned term can be understood at this as the case may be Concrete meaning in invention.

As shown in Figs. 1-3, the utility model provides a kind of tooth inserting tooling, including pedestal 10, is set on the pedestal 10 Support base 20 and mandrel 30 across the pedestal 10 and the support base 20, lead between support base 20 and pedestal 10 It crosses bolt assembly to be detachably connected, mandrel 30 keeps being coaxially disposed with pedestal 10, support base 20, and preferably mandrel 30 is slided with pedestal 10 Dynamic connection.

Support base 20 is equipped with the boss 21 for being used to support workpiece to be processed 100, and the inner peripheral surface of the boss 21 is radially An annular brace platform 22 is extended inwardly, the upper surface of supporting table 22 is less than the upper surface of boss 21, is arranged in the boss 21 There is a positioning sleeve 40, the upper end of the positioning sleeve 40 is circumferentially provided with a plurality of expansion joint 41, and preferably expansion joint 41 is from positioning sleeve 40 Upper surface extend a certain distance to the lower end of positioning sleeve 40 along the axis direction of positioning sleeve 40, the upper end of positioning sleeve 40 is more The stretching portion 42 consistent with 41 quantity of expansion joint is formed under the compartmentation at expansion joint 41.It is distributed along the circumference in supporting table 22 Multiple compact heaps 50 positioned at the inside of the positioning sleeve 40, the preferably quantity of compact heap 50 are four, accordingly, positioning sleeve 40 On stretching portion 42 quantity also be four, each compact heap 50 stretching corresponding with one portion 42 matches, and is waited for stretching Workpieces processing 100.The compact heap 50 is slidably connected with the supporting table 22, and sliding slot is radially provided in supporting table 22 23, the sliding part 51 slided in sliding slot 23 with one on compact heap 50 is additionally provided with a spring 60 in sliding slot 23, and the one of spring 60 End connect with the sliding part 51 of compact heap 50, the connection of one end of the close boss 21 of the other end and sliding slot 23, and spring 60 is compression spring. The peripheral surface of compact heap 50 and the inner wall of the upper end of the positioning sleeve 40 are adapted, and the inner peripheral surface of compact heap 50 is inclined-plane or cone Face, the upper end of the mandrel 30 and the inner peripheral surface of the compact heap 50 are adapted.If the inner peripheral surface of compact heap 50 is inclined-plane, core There are four inclined-planes corresponding with the inner peripheral surface of compact heap 50 for the upper end tool of axis 30.If the inner peripheral surface of compact heap 50 is the conical surface, The upper end of mandrel 30 is a conical surface corresponding with the inner peripheral surface of compact heap 50.Under the action of spring 60, compact heap 50 Inner peripheral surface is held against on the circumferential surface of mandrel 30.The lower end of mandrel 30 is connect with a driving device, and mandrel 30 is filled in the driving It is moved up and down under the driving set, preferably driving device is cylinder 70.

Operation principle：Before being put into workpiece to be processed 100, mandrel 30 moves up a distance under the promotion of cylinder 70, Compact heap 50 under the action of spring 60 radially draw close and abutted with mandrel 30 by elder generation's mandrel 30, then by workpiece to be processed 100 It is placed on boss 21 and is sleeved on simultaneously outside positioning sleeve 40, then mandrel 30 moves down a distance under the promotion of cylinder 70, The upper end of mandrel 30 is matched with the inner peripheral surface of compact heap 50, to which radially compact heap 50 is pushed outwardly, compact heap 50 Peripheral surface then abuts with the inner wall of the upper end of positioning sleeve 40 and the stretching portion 42 on positioning sleeve 40 is pushed to be moved radially outwards, from And by 100 stretching of workpiece to be processed.Entire clamping process only need to operate cylinder 70, make cylinder other than the operation for picking and placeing workpiece 70 liftings, are completed the clamping to workpiece to be processed 100.Therefore, fast to the clamping speed of workpiece.

As being further improved for said program, the outer diameter of the lower end of the positioning sleeve 40 is less than the outer diameter of upper end, described The lower end of positioning sleeve 40 is set in the boss 21.The lower end of positioning sleeve 40, which ensure that, can be sleeved in boss 21, and upper end is then It can be adjusted according to the size of workpiece to be processed 100, i.e., suitable positioning sleeve be replaced according to the size of workpiece to be processed 100 40, so that it may realize that same mandrel 30 coordinates from different size workpieces to be processed 100, and it is again very convenient to replace positioning sleeve 40.

The advantages of basic principles and main features and the utility model of the utility model have been shown and described above, for For those skilled in the art, it is clear that the present invention is not limited to the details of the above exemplary embodiments, and without departing substantially from this In the case of the spirit or essential attributes of utility model, the utility model can be realized in other specific forms.Therefore, no matter From the point of view of which point, the present embodiments are to be considered as illustrative and not restrictive, and the scope of the utility model is by institute Attached claim rather than above description limit, it is intended that will fall within the meaning and scope of the equivalent requirements of the claims All changes are embraced therein.
