Abstract
The invention discloses an exciter eccentric block eccentric distance adjusting mechanism. A main shaft of an exciter is sleeved with an eccentric block connecting disc. An eccentric block is in sliding fit with a guide groove in the eccentric block connecting disc. An oil cylinder is fixed to an outer shell of the exciter. A rotating connecting sleeve is in running fit with a piston rod of the oil cylinder. Two axial holes in the rotating connecting sleeve are in sliding fit with two guide rods on the eccentric block connecting disc respectively. The two ends of a connecting rod are hinged to the eccentric block and the rotating connecting sleeve respectively. A laser emitting device is arranged on a support. The support is fixed to the shell of the oil cylinder. A laser receiving plate is installed on a support fixedly connected with the piston rod. A brake is used for fixing expansion and contraction motions of the piston rod and belongs to public known products of market sales. A laser emitting plate is installed at the portion, between the rotating connecting sleeve and the brake, of the support fixedly connected with the piston rod and is opposite to the laser emitting device. The exciter eccentric block eccentric distance adjusting mechanism has the remarkable advantage of being high in eccentric distance adjusting accuracy.
Description
Technical field:
The present invention relates to a kind of vibrator, particularly a kind of vibrator eccentric block eccentricity regulating mechanism.
Background technology:
In existing vibratory equipment, have eccentric block eccentricity regulating mechanism and have following defect, the degree of regulation of the eccentric throw of eccentric block is lower, and the sealing of swivel joint is poor, fragile, and in adjustment process, eccentric block can not stop moment.
Summary of the invention:
The object of this invention is to provide a kind of a kind of vibrator eccentric block eccentricity regulating mechanism of eccentric throw degree of regulation.
The technical scheme that realizes the object of the invention is, a kind of vibrator eccentric block eccentricity regulating mechanism, comprise vibrator and eccentric block, it is characterized in that: eccentric block terminal pad is set on the main shaft of vibrator, described eccentric block cunning fits in the guide groove on described eccentric block terminal pad, oil cylinder is fixed on the shell of vibrator, the cover that is rotatably connected is rotatably assorted on the piston rod of described oil cylinder, these two axial holes that put that are rotatably connected are joined with two guide rod cunnings that are fixed on described eccentric block terminal pad respectively, the two ends of connecting rod are hinged with described eccentric block and the cover that is rotatably connected respectively, laser beam emitting device is rack-mount, this support is fixed on the housing of oil cylinder, or be arranged on the brake being connected mutually with oil cylinder housing, laser receiver sheet is arranged on the support being connected mutually with piston rod, this brake is for fixed piston rod expanding-contracting action, itself belong to the known products of market sale, laser reflection plate is arranged on the support that is connected mutually of piston rod between be rotatably connected cover and brake, and relative with laser beam emitting device.
The present invention has the remarkable advantage that eccentric throw degree of regulation is high compared with the prior art.
Brief description of the drawings:
Fig. 1 is structural representation of the present invention.
Detailed description of the invention:
The defect existing in order to overcome prior art, the present invention adopts the technical scheme of following embodiment, eccentric block terminal pad 2 is set on the main shaft 1 of vibrator, in the sliding guide groove 3 fitting on described eccentric block terminal pad of described eccentric block 15, oil cylinder 10 is fixed on the shell 11 of vibrator, the cover 4 that is rotatably connected is rotatably assorted on the piston rod 12 of described oil cylinder, these two axial holes that put that are rotatably connected are joined with two guide rods, 14 cunnings that are fixed on described eccentric block terminal pad respectively, the two ends of connecting rod 13 are hinged with described eccentric block and the cover that is rotatably connected respectively, laser beam emitting device 7 is arranged on support 8, this support is fixed on the housing 10 of oil cylinder, or be arranged on the brake 9 being connected mutually with oil cylinder housing, laser receiver sheet 5 is arranged on the support 6 being connected mutually with piston rod, this brake is for fixed piston rod expanding-contracting action, itself belong to the known products of market sale, laser reflection plate 5 is arranged on the support 6 that is connected mutually of piston rod between be rotatably connected cover and brake, and relative with laser beam emitting device.
The eccentric throw Principles of Regulation of eccentric block of the present invention are, first make brake unclamp piston rod state outward, the exciting force producing according to the eccentric distance of eccentric block or amplitude and needed exciting force or amplitude poor, control cylinder action, piston rod stretches out or retreats, in the time that piston rod moves into place, the exciting force that the eccentric distance of eccentric block produces or amplitude are that needed brake moves piston rod locking, and oil cylinder quits work simultaneously.This range finding is to measure axial distance between the axial and eccentric block terminal pad of the cover that is rotatably connected, and this distance can converse the radial distance of eccentric block and vibrator main shaft.
