Description
Technical field
The utility model relates to motor support.
Background technology
The Engine Block Test technology is an important component part of Automobile Measuring Techniques, is also a most complicated part.When carrying out Engine Block Test, generally all carry out on the threst stand of special use.By some special-purpose coupling arrangements, engine is fixed on test-bed during test, and tests after connecting required electricity, gas, water, oil and required instrument and equipment.In prior art, stationary engine generally adopts welding to support, and is highly non-adjustable, consistent for the height between assurance equipment, needs the finishing supporting surface, and can only be supporting with a kind of engine, do not accomplish interchangeability, and versatility is poor.
In recent years, some producer has also processed some adjustable for height motor support, comprises the sleeve of vertical setting and upper opening, is inserted with screw rod in sleeve, and between screw rod and sleeve, by threaded engagement, similar bolt and nut is secondary.The screw rod upper end is connected with engine support frame, and during use, engine is arranged on engine support frame.By forward and reverse rotating screw bolt, engine support frame is moved up and down adjust height.But this support can not reliably be locked screw rod, in use procedure the height of engine support frame can because of vibrations and Action of Gravity Field change, easily affect test result.In addition, when adjusting height, supporting surface can and then rotate, the surface of contact of abrasion engine, and also adjustable extent is little, and intensity is bad, can produce the partial points resonance effect when engine running, and effect is not very desirable, does not realize the three-dimensional adjustable of single support yet.
The utility model content
The purpose of this utility model is to provide a kind of height control complete after the motor support of reliable lock.
the technical scheme that the utility model adopts is motor support, comprise the sleeve shaped of vertical setting and upper end open column, be plugged in screw rod in column from the opening of column upper end, the position that described screw rod stretches out the column upper opening is spirally connected and is equipped with the setting nut adaptive with the external thread of screw rod, and the lower surface of described setting nut is rotatably supported in the column upper end and drive screw rises when forward rotation, drive screw descends during backward rotation, the barrel of described column is provided with from the column top to downward-extension and vertical gap that barrel top is cut open, on the barrel of described vertical gap left and right sides, corresponding being provided with a pair ofly shunk and makes the barrel of column hold screw rod tightly or open with vertical gap when loosening and fastening ear that screw rod is discharged for drive vertical gap under the effect of external force, any one of two described fastening ears is equipped with lock-screw, another is provided with the locking screw pit corresponding with lock-screw and by screwing lock-screw, vertical gap is shunk, also be provided with on described barrel and communicate with the bottom of described vertical gap and cut down groove along the stress of the circumferential extension of column.
Adopt technique scheme, the setting nut lower end is supported on column, can be by self rotating drive screw rod lifting, by applying external force, fastening ear can near or separate, thereby adjust the contraction of vertical gap or open and with screw rod locking or discharge, stress in the barrel wall when stress reduction groove can reduce vertical gap contraction, make the amplitude that actuates of vertical gap lower end become large, thereby reduced the required acting force of screw lock, be beneficial to barrel screw rod is firmly locked, reached the purpose of reliable lock, and the mode of screw lock is easy to operate, and is fixing reliable.
Any one of two described fastening ears is spirally connected and shores the screw that opens of the fastening ear of another when being equipped with forward rotation.Open screw and can overcome the distortion that causes after the long-term locking of column barrel and can't separate with screw rod, be convenient to separating of the inboard barrel of column and screw rod.
It is to extend and length is 1/4 of described column circumference along a side of described vertical gap that described stress is cut down groove.The stress of this form is cut down groove can play good subduing effect of stress and can guarantee the supporting role that column is brought into normal play.
The column lower end of motor support is to be fixed on base plate, described base plate be provided with along left and right directions and along fore-and-aft direction extend and for the time adjustment base plate locked position the U-shaped slotted hole.The U-shaped slotted hole that left and right directions and fore-and-aft direction are set is convenient to realize the position adjustment of motor support make motor support have better adaptability.
Described screw rod upper end is connected with the mount pad leg that the engine mount pad is installed, and described mount pad leg and engine mount pad are assembled together by the dental inlay structure angle of pivot center along continuous straight runs setting adjustablely.The dental inlay structure can realize angular setting easily, thereby can adjust angle after engine is installed on the engine mount pad.
Between described mount pad leg and engine mount pad, the teeth of dental inlay structure are that modulus and the pressure angle of 180 and each teeth is identical.The teeth engagement of this form is accurate, and backlash is little, can substantially eliminate the mutual fricative noise between mount pad leg and engine mount pad, and can realize the adjusting of round values angle between 0 ° ~ 180 °, and is more accurate meticulous.
Described setting nut is the setting nut that has when using with the adaptive hook spanner groove of hook spanner, and hook spanner easy to use realizes that it rotates to adjust highly.Simultaneously apply power with long-armed bar and compare, the use hook spanner can be avoided the interference between armed lever and engine, makes adjustment process more convenient.
The external thread of described screw rod is acme thread.Acme thread root of the tooth intensity is high, and centering is good, and is not easy to wear, and internal and external threads is adjacent to the conical surface and is difficult for looseningly, can adapt to heavier load.
