The normal operation of an engine is guaranteed.
Description
Technical field
The utility model belongs to oil sprayer, Injection Pump Detection range, especially for the detection test stand that detects all kinds of oil sprayers, Injection Pump.
Background technique
Oil sprayer, Injection Pump are the necessary component of DENG, and the quality of its performance has determined the performance quality that diesel oil starts, thereby have determined the performance quality of automobile.Therefore oil sprayer, Injection Pump should regularly detect.Put oil sprayer before this, Injection Pump detects test stand and arises; Oil sprayer, fuel injection pump tester are to detect oil sprayer, the necessary detection facility of Injection Pump; Therefore the stability of oil sprayer, fuel injection pump tester performance; Determined oil sprayer to be detected, oil spout pump performance, and influenced the maintenance direction of people, so the stability of oil sprayer, fuel injection pump tester is very important oil sprayer, Injection Pump.Be used for the test stand ubiquity that oil sprayer, Injection Pump detect at present and following defective: 1. existing test stand generally adopt main motor and high-pressure service pump independent separately be connected the panel beating base of welding with bolt; This Placement; Make the coaxality of motor and high-pressure service pump, because of the distortion of panel beating base when the welding differs greatly.2. adopt the rigid connection of mutual-inserting type coupling between existing test stand ubiquity master's motor and the high-pressure service pump, this Placement makes in the running, because of there are same axis error in main motor and high-pressure service pump, sprains and main motor and high-pressure service pump caused.3. existing test stand generally adopts coupling to be directly installed on above the main motor output shaft, and this Placement makes the rotating speed of winner's motor and high-pressure service pump produce fluctuation because of the instability of voltage, thereby has influenced the accuracy that detects data.4. existing test stand ubiquity counterweight is not enough, and main motor can produce vibration in the running, makes the whole test platform in use because of vibration is shifted, and produces great noise.
(003) because there is above defective in existing test stand; Therefore; Need provide a kind of main motor and high-pressure service pump whole is connected with the panel beating base to improve between coaxality, motor and the high-pressure service pump flexibly connect, have reduce because of voltage instability produce the fluctuation of speed device, reduce to vibrate, the test stand of reduction noise is to satisfy the research and development of oil sprayer, Injection Pump; Produce the needs of detection.
Summary of the invention
The purpose of the utility model just is to the shortcoming of above-mentioned existing technology to provide a kind of coaxality high with not enough, reduce to sprain, stabilization of speed, vibrate little, the oil sprayer of stable performance, Injection Pump detection test stand.
For achieving the above object; It adopts following technological scheme: oil sprayer, Injection Pump detect test stand, comprise frame, and frame is provided with main motor and high-pressure service pump; The coaxial connection of main motor and high-pressure service pump, above-mentioned main motor and high-pressure service pump are co-located on the cast iron worktable on the frame; Connect through flywheel and universal joint between main motor and high-pressure service pump, above-mentioned universal joint comprises two groups of shell fragments, and every group of shell fragment is formed by stacking by the multi-disc lamellar body, and its deformable angle is vertical each other.
The utility model is fixed on main motor and high-pressure service pump on the cast iron worktable; Integral body is connected with bolt with the panel beating base then; Install universal joint additional between motor and the high-pressure service pump and be connected (flexibly connecting); Motor output shaft installs flywheel (key connect be connected with bolt) additional and is connected with universal joint, is connected (be connected with key between coupling and the high-pressure service pump and be threaded) with coupling between universal joint and the high-pressure service pump.
Offer T-slot respectively with respect to main motor and high-pressure service pump on the said cast iron worktable; Can slide along above-mentioned T-slot in the position of main motor and high-pressure service pump; Be convenient to adjust the mounting point; Thereby guaranteed the left-right deviation of coaxality, the center height that high-pressure service pump supports has guaranteed the center height of high-pressure service pump, thereby has guaranteed the last lower deviation of coaxality.
Said universal joint assembly and flywheel link together with bolt, and its universal joint self component also connect and connect with bolt,
Land is connected with bolt with flywheel, and land is connected with bolt with first group of shell fragment simultaneously, and first group of shell fragment and second group of shell fragment separate with a contiguous block; Connect with bolt; Its deformable angle is vertical each other, thereby forms the flexible space of 360 degree, is connected with bearing pin with the connecting plate transition between two pusher dogs and the second group of shell fragment; Pusher dog is connected with the coupling INSERTTYPE, uses bolton simultaneously.
The above each attachment portion is combined, and makes to have formed between motor and the high-pressure service pump to flexibly connect.
Motor output shaft is installed flywheel, makes the rotating speed of motor output tend towards stability, and the rotary inertia when flywheel rotates simultaneously makes that power of motor is able to amplify, and makes its running lighter.
Motor is connected with bolt with the panel beating base together with worktable is whole with high-pressure service pump; Solve the coaxality problem of motor and high-pressure service pump, reduced spraining that hard link brings, reduced the fluctuation of motor speed; Reduce the vibration of whole test platform, thereby strengthened test accuracy.Guarantee the normal operation of motor.
