The tension control device is characterized by comprising a flange plate, a spring sleeve, a spring, a pull rod and an eccentric wheel seat, wherein the spring is arranged in the spring sleeve, the pull rod is arranged in the middle of the spring, spring seats are arranged at two ends of the spring, the front-end spring is sleeved in a spindle, the pull rod is sleeved in the spring seats, a front bearing seat is connected behind the rear spring seat and is sleeved with an adjusting nut in contact with the rear spring seat, a plane bearing is arranged in the front bearing seat, the tail end of the pull rod is sleeved in the bearing, an eccentric wheel is arranged on the eccentric wheel seat, a rear bearing seat is installed on the eccentric wheel seat, a plane bearing is installed between the front bearing seat and a rear bearing, the eccentric wheel is connected with the eccentric wheel seat through an eccentric wheel shaft, and the upper end of the eccentric wheel is connected with a handle. The tension control device is simple in structure, low in cost and capable of controlling tension according to different situations.
Description
Technical field
The present invention relates to a kind of clamp art, particularly relate to a kind of pulling force control device.
Background technology
In lathe process, for elastic expansion clamper, the action of its swelling and strength lathe spindle rear end of being everlasting controls, and the complex structure of present control device, practical inconvenient, cost is high, can not get a desired effect.
Summary of the invention
The present invention is in order to overcome the deficiency of above-mentioned technical problem, and provide a kind of structure simple, cost is low, can control the pulling force control device of pulling force according to different situations.
The technical scheme solved the problems of the technologies described above is as follows:
Pulling force control device, comprise ring flange, spring housing, spring, pull bar and eccentric wheel base, spring housing one end is sleeved on ring flange, one end is fixed in eccentric wheel base, spring is provided with in described spring housing, pull bar is provided with in the middle of spring, both ends of the spring is provided with spring base, front springs is sleeved in main shaft, drag link sleeve is contained in spring base, front-end bearing pedestal is connected with after described spring base below, front-end bearing pedestal outside front is set with the adjusting nut contacted with rear spring seat, plane bearing is provided with in described front-end bearing pedestal, pull bar tail end suit within the bearing, described spring base, pull bar, spring and front-end bearing pedestal are connected with main shaft, with main axis, described eccentric wheel base is provided with eccentric wheel, rear bearing block is arranged on eccentric mounting, front-end bearing pedestal and rear axle are equipped with plane bearing between making, eccentric wheel is connected with eccentric wheel base by camshaft, described eccentric wheel upper end is connected with handle.
Described pull bar front end is provided with collet expander.
Described spring housing and eccentric wheel base are threaded connection.
Adopt such scheme, when pulling handle, eccentric wheel presses to rear bearing block due to the displacement difference of bias, be passed to and the front-end bearing pedestal of integrated spindle axis and pull bar by bearing, spring pressurized is bounced back, and pull bar moves to spindle nose, and this displacement is exactly eccentric displacement, the expansion pulling force of such head also just disappears, and now can unload workpiece.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
As shown in the figure, pulling force control device, comprise ring flange 1, spring housing 2, spring 3, pull bar 4 and eccentric wheel base 5, spring housing 2 one end is sleeved on ring flange 1, one end is fixed in eccentric wheel base 5, spring 3 is provided with in spring housing 2, pull bar 4 is provided with in the middle of spring 3, spring 3 two ends are provided with spring base 14, fixing spring, front springs cover for seat is contained in main shaft 6, pull bar 4 is sleeved in spring base 14, front-end bearing pedestal 8 is connected with below after spring base, front-end bearing pedestal 8 outside front is set with the adjusting nut 7 contacted with rear spring seat, plane bearing is provided with in front-end bearing pedestal 8, pull bar 4 tail end suit within the bearing, spring base 14, pull bar, spring 3 and front-end bearing pedestal 8 are connected with main shaft 6, with main axis, eccentric wheel base 5 is provided with eccentric wheel 9, rear bearing block 10 is arranged on eccentric mounting, between front-end bearing pedestal 8 and rear bearing block 10, plane bearing is housed, eccentric wheel 9 is connected with eccentric wheel base 5 by camshaft 11, eccentric wheel 9 upper end is connected with handle 12, when pulling handle 12, eccentric wheel 9 presses to rear bearing block 10 due to the displacement difference of bias, be passed to and the front-end bearing pedestal 8 of main shaft 6 one and pull bar 4 by bearing, spring 3 pressurized is bounced back, pull bar 4 moves to main shaft 6 head, this displacement is exactly the displacement of eccentric wheel 9, the expansion pulling force of such head also just disappears, now workpiece can be unloaded., handle 12 resets, and return to original seat at effect lower link 4 and the rear end bearing 10 of spring 3, workpiece is just clamped
Preferably, pull bar front end is provided with collet expander, realizes the swelling of workpiece and loosens.
Further, spring housing is connected by screw thread 13 with eccentric wheel base, improves the connection fastness of spring housing 2 and eccentric wheel base 5.
The present invention is not limited to described embodiment, and those skilled in the art, not departing from spirit of the present invention namely openly in scope, still can do some and revise or change, therefore the scope that the scope of the present invention limits with claims is as the criterion.
