Abstract
The utility model discloses a mandrel self-centering rod clamping and withdrawing device, which consists of a power cylinder, racks, clamping rolls and a reducer motor, wherein a power output shaft of the power cylinder is connected with one end of each rack, the two racks are respectively engaged with a gear on each eccentric shaft in a transmission way, each eccentric shaft is provided with the clamping roll, and the clamping rolls are connected with the reducer motor through a shaft. The mandrel self-centering rod clamping and withdrawing device has the characteristics of relatively simple structure, good clamping conveying effect and easiness in processing and lower cost.
Description
Technical field
The utility model belongs to the machining equipment technical field, especially relates to a kind of mandrel self-centering bar that needs material straight-line motion and self-centering to pinch extraction and pinches withdrawing device.
Technical background
In field of machining, mostly be by rack-and-gear for bar centering clamping at present and carry out synchronous slide block type mechanism, the bidentate of employing wheel ingear pivoted axle mechanism is also arranged, this dual mode can be realized the function that bar centering clamping is carried, but its complex structure, to the requirement height of part processing, cost height, Installation and Debugging difficulty.
Summary of the invention
The purpose of this utility model be to improve the deficiency of prior art and provide that a kind of structure is simple relatively, effective, handling ease is carried in clamping, the mandrel self-centering bar of lower-cost novel bar pinches withdrawing device.
The purpose of this utility model is to realize like this, a kind of mandrel self-centering bar pinches withdrawing device, form by power cylinder, tooth bar, nip rolls and reducing motor, the power take-off shaft that is characterized in power cylinder is connected with an end of two tooth bars, two tooth bars respectively with two eccentric shafts on meshed transmission gear, each eccentric shaft is provided with nip rolls, and nip rolls links to each other with reductor by axle.
The utility model compared with prior art has following distinguishing feature and good effect: the utility model is that the power take-off shaft of power cylinder is connected with an end of two tooth bars, two tooth bars respectively with two eccentric shafts on meshed transmission gear, each eccentric shaft is provided with nip rolls, nip rolls links to each other with reductor by axle, adopted the eccentric shaft type design, the eccentric shaft axle bed is simpler than the processing of slider type axle bed and swing arm profile shaft seat, cost is low, when the eccentric shaft type structure is installed simultaneously, adjustment to the center is simpler than existing mechanism, and the eccentric shaft type structure is bigger to the gripping power of bar, can enough less power just can realize the clamping effect identical with existing structure.
Description of drawings
Below in conjunction with accompanying drawing and example the utility model is described in further detail
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 bows to view for Fig. 1's.
The specific embodiment
Embodiment, a kind of mandrel self-centering bar pinches withdrawing device, with reference to Fig. 1, Fig. 2, the power take-off shaft that is power cylinder 4 is connected with an end of two tooth bars 6, two tooth bars 6 respectively with two eccentric shafts 2 on meshed transmission gear, each eccentric shaft 2 is provided with nip rolls 3, nip rolls 3 links to each other with reductor 1 by axle, power cylinder 4 can be cylinder, hydraulic actuating cylinder, and present embodiment adopts hydraulic actuating cylinder, and this constitutes a kind of structure of the present utility model.
The utility model is that power cylinder 4 promotes tooth bar 6 motions, the gear that tooth bar 6 drives on two eccentric shafts 2 makes two eccentric shafts 2 inwardly rotate synchronously, because the off-centre of axle, so when eccentric shaft 2 inwardly rotates simultaneously, nip rolls 3 on the eccentric shaft 2 clamps bar 5, thereby realizes the clamping to bar 5, and nip rolls 3 links to each other with reductor 1 by axle, clamp back reductor 1 and rotate 3 rotations of drive nip rolls, make in bar 5 slave units to pinch or extract out.
