Description
Technical field
The present invention relates to a kind of frock clamp, relate in particular to engine net torque detection fixture, whether meet the requirements with the clean moment of torsion of accurate detection of engine.
Background technology
In the assembling process of motor car engine, requirement according to the industry relevant criterion, need be after crankshaft installed be finished, after the installation of connecting rod piston assembly and final assembly finish after three phases carry out the detection of the clean moment of torsion of bent axle, whether up to standard with the size of judging frictional resistance between each kinematic pair of engine.Traditional detection mode is to be undertaken by the manual rotary crankshaft of workman, the workman judges with feel, assembling experience, owing to there is not quantitative criteria, the accuracy of this detection mode is relatively poor, make that the size of frictional resistance does not have up to standard yet can passing through to detect between each kinematic pair of engine, thereby cause engine capacity, moment of torsion to descend, oil consumption increases, row's temperature rise.What is more, and engine can not normally start, and ressembles after must dismantling, and causes workman's duplication of labour like this, and working strength of workers increases, and efficiency of assembling is low.
Summary of the invention
Whether technical matters to be solved by this invention is to provide a kind of engine net torque detection fixture, meet the requirements with the clean moment of torsion of accurate detection of engine.
Technical scheme of the present invention is as follows: a kind of engine net torque detection fixture, be provided with respectively in the both sides that connect the cover stage casing of a through-pipe structure and connect the cover leading portion and to connect the cover back segment, the three is fixed together and axial line coincides, the described cover leading portion that connects also is through-pipe structure, it is suitable to connect on cover inwall of leading portion and the engine crankshaft lubricating oil pump erecting bed stage, the described cover back segment that connects is sleeved on the reference column of definite value torque spanner end, and the axial line that connects cover axial line of back segment and definite value torque spanner is perpendicular.
Adopt above technical scheme, the three phases that in the motor car engine assembling process, needs the clean moment of torsion of detection of engine, promptly after crankshaft installed is finished, after the installation of connecting rod piston assembly and after final assembly finishes, all can carry out the detection of clean moment of torsion by the present invention.During detection, on the definite value torque spanner, set the size of torque value earlier according to the requirement of assembling stage, before will connecing cover then, the stage casing is sleeved on the engine crankshaft, lubricating oil pump installation step section is arranged in connects the cover leading portion, both clearance fit, the axle body in the lubricating oil pump erecting bed stage outside are arranged in and connect the cover stage casing.Rotate the definite value torque spanner, the definite value torque spanner drives bent axle and rotates together by connecing cover, when the frictional resistance between this assembling stage kinematic pair reaches requirement (being the setting value of definite value torque spanner), the definite value torque spanner send " clickly " prompting sound; Do not send if there is prompting sound, the clean moment of torsion that can judge this assembling stage does not reach requirement.
Whether the clean moment of torsion that the present invention only needs several seconds kinds just can detect engine meets the requirements, not only fast but also accurate; It can prevent the unassembled qualified subsequent processing that just flows into of engine kinematic pair, has ensured the operate as normal of engine, and the duplication of labour of having avoided repeated disassembled and assembled to bring greatly reduces working strength of workers, and has effectively improved the efficiency of assembling of engine.
The above-mentioned cover leading portion that connects docks and fixes by welding with connecing the cover stage casing, and both surface of contact are step, so both have been convenient to welding, can strengthen the reliability that both connect again.
In order to guarantee that engine crankshaft overlaps rotation synchronously with connecing, the above-mentioned front end that connects cover leading portion inwall is taper, and the rear end is circular, and the stage casing is made up of four planes and four arc surfaces, and wherein four planes are parallel in twos, and pass through the arc surface transition between the two adjacent planes.
The above-mentioned cover back segment that connects also is through-pipe structure, be sleeved on by center pit on the reference column of definite value torque spanner end, the outer wall that connects cover back segment front end stretches out, and forms disk, this disk is arranged in and connects the cover stage casing and with to connect cover stage casing welding fixing, both surface of contact also are step.Connect before, during and after the cover three sections and adopt split-type structurals, and fixing by welding, handling ease, low cost of manufacture like this, strength of joint is secure.
Have two spacing holes that communicate with its center pit above-mentioned connecing on the outer wall that overlaps the back segment rear portion, the axial line of two spacing holes point-blank; Two telescopic steel balls are housed on the shaft of described definite value torque spanner reference column, and the fraction ball body of this steel ball is arranged in corresponding spacing hole.Steel ball is spacing by the hole wall that connects cover back segment spacing hole, when control steel ball retraction, can will connect cover and take off from the definite value torque spanner, and it is all very convenient to connect between cover and the definite value torque spanner dismounting.
Beneficial effect: the present invention has and is skillfully constructed, implements characteristics such as easy, simple to operate, it can be quickly and accurately detects the clean moment of torsion of engine, ensured the assembly quality of engine, the duplication of labour of having avoided repeated disassembled and assembled to bring, greatly reduce working strength of workers, and effectively improved the efficiency of assembling of engine.
