Description
Technical Field
The utility model relates to a clamping mechanism, especially a buffering formula auto-lock clamping mechanism.
Background
In industrial production, assembly, disassembly and other activities, various clamping mechanisms are often required to fix a workpiece so as to implement specific operations. When some workpieces which cannot bear direct impact or dangerous goods are clamped by a traditional mechanism driven by a cylinder, an oil cylinder and the like, more problems exist. Such as a projectile. The lead of the abandoned shell needs to be dismantled, gunpowder is hollowed out of the shell, and the shell belongs to a dangerous article and can explode once being impacted greatly, so that the shell is clamped and fixed by a traditional clamping mechanism, and certain potential safety hazards exist. There is therefore a need for a method or apparatus that addresses the above-mentioned problems.
Disclosure of Invention
The utility model relates to a solve the above-mentioned not enough that prior art exists, provide a simple structure, design benefit, rationally distributed can not produce excessive rigidity and strike, and has self-locking function's clamping mechanism.
The technical solution of the utility model is that: the utility model provides a buffering formula auto-lock clamping mechanism which characterized in that: the mechanism comprises a driving mechanism shell 1, a driving mechanism is arranged in the driving mechanism shell 1, the driving mechanism comprises a worm 2 supported on the driving mechanism shell 1 through a bearing, a worm wheel 3 is also rotatably supported in the driving mechanism shell 1, the worm 2 is matched with the worm wheel 3, a screw rod 4 is connected in the worm wheel 3, one end of the worm 2 is positioned outside the driving mechanism shell 1,
the bottom of the driving mechanism shell 1 is also connected with a pressure rod shell 5, a pressure sleeve 6 is connected in the pressure rod shell 5 in a sliding manner, a nut part 7 is arranged at the top of the pressure sleeve 6, the nut part 7 is in threaded connection with the bottom of the screw rod 4, a pressure rod 9 is movably connected in a bottom cavity of the pressure sleeve 6, a pressing block 10 is arranged at the bottom end of the pressure rod 9, a limiting part 8 is arranged on the pressure rod 9, a plurality of disc springs 11 which are distributed in a stacked manner are sleeved on the pressure rod 9 above the limiting part 8,
the driving mechanism shell 1 is provided with an oil window 12 and an oil filling hole 13, and the side surface of the pressure lever shell 5 is provided with a lubricating oil filling hole 14.
Compared with the prior art, the utility model, have following advantage:
the buffer type self-locking clamping mechanism with the structural form is simple in structure, ingenious in design and reasonable in layout, aims at the problem that no buffer exists when the traditional clamping mechanism performs clamping action, designs a special structure, generates pressure through a plurality of disc springs which are stacked together, and ensures that a clamped workpiece cannot bear large and direct pressure, so that the quality or safety of a product is ensured; meanwhile, the worm and gear transmission pair is matched to transmit motion by a thread structure, self-locking can be realized by the mode, even if a driven motor fails, a pressing block part can be guaranteed to clamp a workpiece all the time, and the safety is better. And the manufacturing process is simple, the manufacturing cost is low, so that the novel LED lamp has multiple advantages, is particularly suitable for popularization and application in the field, and has a very wide market prospect.
Drawings
Fig. 1 is a schematic structural diagram of an embodiment of the present invention.
Detailed Description
The following description will explain embodiments of the present invention with reference to the drawings. As shown in fig. 1: a buffer type self-locking clamping mechanism comprises a driving mechanism shell 1, wherein a driving mechanism is arranged in the driving mechanism shell 1, the driving mechanism comprises a worm 2 supported on the driving mechanism shell 1 through a bearing, a worm wheel 3 is also rotatably supported in the driving mechanism shell 1, the worm 2 is matched with the worm wheel 3, a screw rod 4 is connected in the worm wheel 3, one end of the worm 2 is positioned outside the driving mechanism shell 1,
the bottom of the driving mechanism shell 1 is also connected with a pressure rod shell 5, the pressure rod shell 5 is connected with a pressure sleeve 6 in a sliding way, the top of the pressure sleeve 6 is provided with a nut part 7, the nut part 7 is in threaded connection with the bottom of the screw rod 4, a pressure rod 9 is movably connected in a bottom cavity of the pressure sleeve 6, the bottom end of the pressure rod 9 is provided with a pressing block 10, the pressure rod 9 above the limiting part 8 is sleeved with a plurality of disc springs 11 which are distributed in a stacked manner,
the driving mechanism shell 1 is provided with an oil window 12 and an oil filling hole 13, and the side surface of the pressure lever shell 5 is provided with a lubricating oil filling hole 14.
The utility model discloses buffering formula auto-lock clamping mechanism's working process as follows: connecting the output end of a driving motor with one end of a worm 2 positioned outside a driving mechanism shell 1, starting the driving motor, rotating the worm 2, and driving a worm wheel 3 and a screw rod 4 to rotate together;
because the bottom end of the screw rod 4 is in threaded connection with the nut part 7, and the nut part 7 connected with the pressing sleeve 6 cannot rotate relative to the pressing rod shell 5, the rotation between the screw rod 4 and the nut part 7 can drive the pressing sleeve 6 to do longitudinal linear motion relative to the pressing rod shell 5, when a pressing block 10 of a pressing rod 9 on the bottom end of the pressing sleeve 6 is in contact with a clamped workpiece, the pressing sleeve 6 continues to move downwards, the pressing rod 9 moves upwards relative to the pressing sleeve 6, all disc springs 11 are compressed in the process, and the pressure borne by the workpiece completely comes from the elastic force of the disc springs 11;
after the operation is finished, the driving motor drives the worm 2 to rotate reversely, the actions are performed reversely, and the workpiece can be taken away after the pressing block 10 is separated from the contact with the workpiece;
because the transmission mechanism in the mechanism is a worm gear and a screw nut which are in threaded connection with each other, the mechanism has a good self-locking function, even if the driving motor fails, the mechanism stops acting, and the safety can be effectively ensured.
