Description
Technical field
This utility model relates to a kind of engine belt pulley centralising device, specifically one and utilizes radial light curtain and geometry to become face principle at 3, checks belt pulley vertical angle, level angle and coplane degree thus carries out the device of centering.
Background technology
The alignment degree of belt wheel system of engine is the most crucial to the aging effects of belt, misaligning of belt pulley can cause abrasion quickening, energy consumption increase, extra vibration and noise to even result in belt pulley inefficacy, therefore dispatch from the factory in arranging process at electromotor, need to detect the alignment degree of belt train.And the alignment degree detection of belt pulley is main by estimating or three-coordinate instrument detection.The reliability of range estimation centering is poor, undoubtedly, utilizes the detection equipment such as three-coordinates measuring machine, also can complete this detection, but from the point of view of efficiency and economy point, in actual production process, it is ensured that certainty of measurement, and realizes on-line quick detection and be just particularly important.
Summary of the invention
The deficiency being prior art and existing to be solved in the utility model, it is desirable to provide a kind of accuracy of detection is high, quick engine belt pulley centralising device simple to operate.
Solve the problems referred to above and the technical scheme is that engine belt pulley centralising device, including discharger and reception device, described discharger includes generating laser, magnetic cushion block and multiple first magnetic piece, described generating laser adsorbs on the surface of described magnetic cushion block, and the first described magnetic piece is embedded in the blind slot that the described magnetic cushion block back side is offered；Described receive device include one to medium ring, one group be embedded in described the second magnetic piece in medium ring and three are arranged on described to the scale on medium ring.
Engine belt pulley centralising device of the present utility model, it is mainly characterized by: generating laser and to medium ring, it is respectively positioned in two belt pulley sides, the radial light curtain of the plane sent of generating laser is utilized to become face principle with to 3 of medium ring, can check that belt pulley vertical angle, level angle and coplane degree determine whether alignment immediately, by mating the magnetic cushion block of different-thickness, this device is applicable to the belt pulley under different model size, different mounting condition.Therefore, this utility model achieves the real-time measurement of alignment degree between two belt pulleys.It has the ability quickly measured at inter process.This apparatus structure is the compactest, easy to operate, overcomes error and the defect of three-dimensional coordinates measurement cycle length of range estimation centering.Showing after actually used, reliability and accuracy of alignment are the highest, for detecting in the occasion that the frequency is higher, demonstrate the biggest superiority, open new thinking for belt pulley centering.
Another important feature of the present utility model is that discharger has magnetic cushion block, on the one hand owing to generating laser is with magnetic absorption device, and both convenient operations, also ensure that generating laser stably adsorbs with magnetic cushion block when measuring simultaneously；On the other hand by selecting the magnetic cushion block of different-thickness, it is applicable to various types of belt pulleys that race does not waits to lateral distance.
According to this utility model, the bottom of the blind slot that the described magnetic cushion block back side is offered is additionally provided with copper billet, can increase the magnetic of magnetic piece.
According to this utility model, described scale is arranged on described on medium ring by cruciform slot screw, and according to belt pulley physical location groove on scale.
According to this utility model, described to being further opened with one group of " u "-shaped radial indentation on medium ring, make medium ring is not interfered with other part.
According to this utility model, the described ring body back side to medium ring is further opened with one group of boss, to reduce the contact area with belt pulley, it is ensured that vertical with belt pulley axis.
Accompanying drawing explanation
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings.
Fig. 1 is the structural representation of this utility model engine belt pulley centralising device.
Fig. 2 is this utility model use state diagram when detection.
Fig. 3 is the K direction view of Fig. 2.
In figure, 1-generating laser, 2-magnetic cushion block, 3-copper billet, 4-the first magnetic piece, 5-is to medium ring, 6-the second magnetic piece, 7-cruciform slot screw, 8-scale, 9-" u "-shaped radial indentation, 10-boss, 11-blind slot, 12-laser beam emitting head.
Detailed description of the invention
With reference to Fig. 1, engine belt pulley centralising device of the present utility model, including discharger and reception device.
Described discharger includes generating laser 1, magnetic cushion block 2 and multiple first magnetic piece 4, and described generating laser 1 adsorbs the surface at described magnetic cushion block 2, and the first described magnetic piece 4 is embedded in the blind slot 11 that described magnetic cushion block 2 back side is offered.The bottom of the blind slot 11 that described magnetic cushion block 2 back side is offered is additionally provided with copper billet 3.
In conjunction with Fig. 2, the described device that receives includes that medium ring 5, a group is embedded in and described is arranged on described to the scale 8 on medium ring 5 to the second magnetic piece 6 in medium ring 5 and three by one.The scale 8 stated is arranged on described on medium ring 5 by cruciform slot screw 7.And according to belt pulley physical location groove on scale.Described to being further opened with one group of " u "-shaped radial indentation on medium ring 5, make medium ring is not interfered with other part.The described ring body back side to medium ring 5 is further opened with one group of boss 10, to reduce the contact area with belt pulley, it is ensured that vertical with belt pulley axis.Described " u "-shaped radial indentation is arranged on boss 10 region.
With reference to Fig. 2 and Fig. 3, operational approach of the present utility model is as follows:
Magnetic cushion block 2 being first adsorbed in crankshaft pulley wheel side, then is adsorbed on magnetic cushion block 2 by generating laser 1, the laser beam emitting head 12 of generating laser 1 is arranged on end face, is adjusted to make it just to medium ring 5.
Medium ring 5 being adsorbed at lower section belt of air compressor wheel side, make back side boss 10 and belt pulley contacts side surfaces, guarantee smooth location simultaneously, open generating laser 1, the radial light curtain of plane of generating laser is utilized to become face principle with to 3 of medium ring, can check that belt pulley vertical angle, level angle and coplane degree determine whether alignment immediately, as light curtain illuminates the scale on three scales 8 simultaneously, i.e. represent the two accurate centerings of belt pulley.On different belt pulleys, can be according to the difference of race to crank pulley lateral distance X and race to belt of air compressor wheel side distance Y value, the magnetic cushion block of coupling different-thickness, does not change the groove of scale, is i.e. applicable to the belt pulley under different model size, different mounting condition.
