Abstract
The invention provides a new vibration device with a simple structure for a block-making, which comprises a vibration platform, a servo controller, four servo motors and four eccentric shafts. Each two eccentric shafts are in a group and each two eccentric shafts are symmetrically arranged on the lower part of the vibration platform, wherein, two servo motors are arranged on the horizontal side of the vibration platform and are respectively transmission connected with one group of the eccentric shaft, another two servo motors are arranged on the other horizontal side of the vibration platform and are respectively transmission connected with the another group of the eccentric shafts. The servo motors are electrically connected with the servo controller. As a servo controller synchronously controls a plurality of servo motors, the outputting of all the servo motors are toughly synchronous in order to lead al the eccentric shafts to connect with the outputting end of all the servo motors in a tough synchronization way, thus not only simplifying the structure, but also leading the vibration platform, splint and die box to strictly generate a one dimensional vibration, therefore, the service life of the vibration platform, the splint and the die box is prolonged and the block quality is greatly promoted.
Description
Technical field
The present invention relates to a kind of building block machine, particularly a kind of novel type block machine vibrator.
Background technology
On March 14th, 2007, the Chinese patent CN2878009 of bulletin disclosed the online amplitude modulated oscillations device of a kind of novel type block machine, this device is provided with casing, rotary shaft, gear, shift fork, eccentric block, straight line driving mechanism, power input connecting piece, rotary shaft, gear, shift fork, eccentric block are installed in the casing, gear is installed on the rotary shaft by the driving coupling part, eccentric block is installed on the vibrating shaft of the axle head that circles round, power input connecting piece is connected in the external part of rotary shaft, and shift fork connects gear and the straight line driving mechanism outer with being arranged on casing connects.Though this kind vibrating device can be realized online amplitude modulation, its structure is complicated especially, maintaining inconvenience.In general, known vibrating device comprises two rotating shafts and is located at the eccentric block of two identical weight in the rotating shaft respectively that by the synchromesh gear engaged transmission, the axial end of a rotating shaft wherein is provided with by motor-driven belt pulley between two rotating shafts.When belt pulley rotated under the motor effect, two rotating shafts were rotated under the effect of synchromesh gear like this, did the synchronous backward rotation thereby be located at two eccentric blocks in the rotating shaft, and then produced exciting up and down.Because the size of moulding box is bigger, need many group eccentrically weighted shafts to carry out exciting like this, corresponding needs are organized meshing gear more and are driven, and whole transmission mechanism is complicated heavy, requires powerful drive motors to drive, and equipment cost and operation cost are all very high.
Summary of the invention
The object of the present invention is to provide a kind of novel type block machine vibrator simple in structure, with low cost.
The technical solution adopted in the present invention is such: a kind of novel type block machine vibrator, the involving vibrations platform, servo controller, four servo motors and four eccentrically weighted shafts, per two of described four eccentrically weighted shafts are one group, two eccentrically weighted shafts of each group are symmetrically set in the shaking platform below, wherein two servo motors are located at the horizontal side of shaking platform and are in transmission connection with one group of eccentrically weighted shaft wherein respectively, other two servo motors are located at the horizontal opposite side of shaking platform and are in transmission connection with other one group of eccentrically weighted shaft respectively, and each servo motor is electrically connected with servo controller.
Above-mentioned novel type block machine vibrator, described each eccentrically weighted shaft are made up of rotating shaft and some eccentric blocks of being located on the same phase place of rotating shaft respectively, and the eccentric block of two rotating shafts on same group of eccentrically weighted shaft on it is symmetrical arranged.
By adopting the aforementioned techniques scheme, the invention has the beneficial effects as follows: control four servo motors simultaneously by a servo controller, the output of each servo motor is synchronously strict, make that four eccentrically weighted shafts that are connected with each servo motor output are synchronously strict, thereby can under the situation that guarantees equal exciting force, reduce the power of servo motor greatly, because shaking platform, supporting plate and moulding box can be kept strict one dimension vibration, the flexural deformation that two-dimension vibration causes can not appear, thereby the service life that can improve the platform that shakes, supporting plate and moulding box greatly, cut operating costs; This structure is saved the many groups meshing gear in the known vibratory apparatus in addition, reduces rotary inertia, helps the startup and the braking of vibrating device, and then avalanche when avoiding the building block demoulding.

The specific embodiment
With reference to figure 1, Fig. 2, embodiment discloses a kind of novel type block machine vibrator, its involving vibrations platform 1, four eccentrically weighted shafts 2, servo controller (not shown) and four servo motors 3, described shaking platform 1 is consistent with known shaking platform, it is located at the below of building block machine moulding box and supporting plate, it carries out jolt ramming for the concrete in the moulding box indirectly by supporting plate, 2 per two one group of described four eccentrically weighted shaft are as a pair of below of being located at shaking platform 1 respectively symmetrically, each eccentrically weighted shaft 2 is made up of rotating shaft 21 and four eccentric blocks 22 being located in the rotating shaft 21, four eccentric blocks 22 are positioned at the same phase place of rotating shaft 21, for shaking platform 1 is produced maximum exciting force, two rotating shafts 21 of every pair of eccentrically weighted shaft 2 are symmetrically set in the below of shaking platform 1, and with the phase place of two rotating shafts 21 of a pair of eccentrically weighted shaft 2 eccentric block 22 on it symmetry just, wherein two servo motors 3 are located at shaking platform 1 a horizontal side and are in transmission connection by shaft coupling 23 and one group of eccentrically weighted shaft 2 wherein respectively, described each servo motor 3 is in transmission connection by shaft coupling 23 and each rotating shaft 21 respectively, other two servo motors 3 are located at shaking platform 1 horizontal opposite side and are in transmission connection with other one group of eccentrically weighted shaft 2 respectively, each servo motor 3 is electrically connected with same servo controller (not shown) respectively, what each servo motor 3 received like this is the power supply of same frequency, and each servo motor 3 is with same speed, same turning to drives each eccentrically weighted shaft 2 rotation.Because servo motor 3 is oppositely arranged, thereby in four rotating shafts 21, having two just then two counter-rotatings, and the eccentric block phase place on two groups of eccentrically weighted shafts 2 is arranged on the position of symmetry, and then drive the exciting force that each eccentric block 22 produces maximum, shaking platform 1 is carried out exciting.
Need to prove, shaking platform of the present invention below can be provided with eight eccentricity excitation points, the exciting point of the platform that shakes is distributed rationally, the platform of guaranteeing to shake can strictness be done the one dimension forced vibration, each eccentricity excitation point that thinking is set is consistent with the aforementioned techniques scheme, so that the maximum exciting force of generation under the driving of servo motor, therefore the eccentric block phase place in necessary setting in pairs of described eccentricity excitation point and the corresponding rotating shaft is just opposite.
