Description

Heart test device

The present invention relates to a centering test device, and more particularly to a device suitable for centering a motor and a hydraulic pump.

Referring to Figures 1 and 2, a general centering test device is used to align the axes of a motor 11 and a hydraulic pump 12 to facilitate coupling of the motor 11 and the hydraulic pump 12 with a coupling. The centering test device includes a platform 13 , a base 14 slidably disposed on the platform 13 , four horizontal adjustment screws 15 penetrating the platform 13 and the base 14 , and a base 14 a gantry 16 located above the pedestal 14 at intervals in the up-and-down direction, four height adjusting screws 17 penetrating the platform 13, the pedestal 14 and the gantry 16 in a height direction, and one fixed to the gantry 16 and A fixing plate 18 for the hydraulic pump 12 to be locked. The platform 13 and the base 14 have axial chutes 19 extending in the axial direction of the hydraulic pump 12 and provided for the horizontal adjustment screws 15.

When the centring program is performed, the hydraulic pump 12 is firstly fixed to the fixed plate 18, and the hydraulic pump 12 faces the motor 11. Then, the susceptor 14 is tapped along the axial direction of the hydraulic pump 12 to move the horizontal adjusting screws 15 along the axial sliding slots 19 to drive the susceptor 14 to displace the hydraulic pressure. The pump 12 is axially displaced. The height of the gantry 16 relative to the pedestal 14 can be adjusted by the height adjusting screws 15 to adjust the height position of the hydraulic pump 12.

However, when the operator taps with a tweezers or pushes with a crowbar, it is difficult to accurately control the biasing force, so that the horizontal distance between the hydraulic pump 12 and the motor 11 cannot be accurately adjusted, and the centering accuracy is lowered. When adjusting the height position of the hydraulic pump 12, the height adjustment screw 17 needs to be loosened, and after adjusting the height position of the gantry 16, the screw is tightened again, and the adjustment is also performed after the level adjustment in the adjustment process. Whether the gantry 16 is horizontal or not is very inconvenient.

Therefore, the purpose of the present invention is to provide a centering test device that is more precise and convenient to adjust.

Therefore, the novel centering test device is suitable for performing a centering test on a motor and a hydraulic pump. The centering test device comprises a base unit, a fixed unit disposed on the slide table, and a pair of bit units.

The base unit includes a base, a lead screw disposed on the base and extending along a first axial direction, and a screw disposed on the lead screw and movable by the lead screw to reciprocate along the first axial direction Moving slides. The alignment unit includes a fixing plate that is disposed on the fixing unit and defines a mounting space, and is disposed in the installation space and defines a setting hole, and is suitable for the The adapter ring of the hydraulic pump lock.

The utility model has the advantages that: by adjusting the lead screw, the sliding table can be displaced along the first axial direction relative to the base, so that the hydraulic pump is displaced in the axial direction without tapping with a tweezers and fine-tuning The amount of displacement effectively improves the accuracy. The height of the hydraulic pump can be changed quickly and conveniently by changing the height position of the fixing plate on the fixing unit. The pedestal is pre-designed to be concentric with the motor, and the different fixing plates can be used to fine-tune the position of the center of the heart, without the need to use the iron skid to greatly improve the convenience and precision.

A slide table 53 disposed on the lead screw 52 and an anti-offset mechanism 54 disposed on the bottom surface of the slide table 53 at intervals in the first axial direction A. Each of the anti-offset mechanisms 54 has two mounting blocks 541 spaced apart along the second axial direction B, and two limiting members 542 for respectively inserting the mounting blocks 541 along the second axial direction B. Each of the limiting members 542 has an outer top surface 543 facing the base 51 and spaced apart from the base 51 by 0.1 mm in the first axial direction A. The outer top surface 543 is used to abut against the base 51 to prevent the sliding table 53 and the base 51 from shifting relative to each other, and the parallelism is less than 0.1 mm, so as to adjust the parallelism.

Referring to FIG. 3, FIG. 5 and FIG. 6, the fixing unit 6 includes a bracket 61 having a U-shaped cross section and disposed on the sliding table 53, and the detaching unit 7 is detachably fixed to the bracket 61. Locating pin 62 on. The aligning unit 7 includes a fixing plate 71 that is rectangular and defines a circular mounting space 710. The locking plate 71 is locked on the fixing plate 71 and located in the mounting space 710 and defines a setting hole. The adapter ring 72 of the 720, and a lock on the adapter ring 72 are located in the setting hole 720, and define a positioning washer 73 for the port 730 through which the hydraulic pump 4 passes. The fixing plate 71 is disposed at a center point of the mounting space 710 corresponding to the motor 3 such that the axis line of the motor 3 is parallel to the first axial direction A. The opposite ends of the connecting ring 72 along the first axial direction are respectively locked to the bracket 61 and the flange 41 of the hydraulic pump 4. The positioning washers 73 are respectively locked on the opposite sides of the first axial direction A on the engaging ring 72 and the flange 42 of the hydraulic pump 4. The fixing plate 71, the engaging ring 72 and the positioning washer 73 can be designed in advance for different specifications, so that when corresponding to the hydraulic pump 4 of different specifications, a suitable size can be quickly found.

By rotating the lead screw 52, the sliding table 53 can be moved along the first axial direction A, so that the hydraulic pump 4 moves along the axial direction of the motor 3. This adjustment method does not need to be hammered. There is no problem that it is difficult to control the force, so it is possible to make a slight adjustment to improve the precision. The base 51 is fixed to the platform 2 corresponding to the motor 3, and the fixing plate 71 is concentric with the motor 3, so that it is not necessary to push the iron sled along the second axial direction B, thereby saving effort. The fixing plate 71 can replace the set height to change the height position of the hydraulic pump 4. The adjustment process only needs to remove and insert the positioning pin 62, and the adjustment is simple and fast. The anti-offset mechanisms 54 maintain parallelism such that the hydraulic pump 4 can remain parallel when axially displaced.

In summary, the present invention can achieve micro-spinning or simple operation through the cooperation of various structures, thereby effectively improving the adjustability and accuracy, so that the purpose of the present invention can be achieved.
