Technical field
The present invention relates to educational aid technical field more particularly to a kind of Automobile Service teaching engine teaching demonstration devices.
Background technology
In Automobile Service school, the related course of engine, due to engine structure complexity, the change such as started can be carried out to student
Fast device and related part need to be shown explanation to student.Generally it is that will directly start when imparting knowledge to students in existing situation
Machine is positioned over desktop and is directly explained.But engine is positioned over desktop, can only intuitively expose top position, the zero of engine
Part or put-put need multi-surface exhibition, and since engine has oil, and artificial overturning is easy to make hand dirty, to need one
Kind device, it is convenient to be overturn in teaching.
Invention content
The technical problem to be solved in the present invention is：It is simple in structure how one kind is provided, it is easy to operate, it can be conducive to
The engine teaching demonstration device for realizing engine clamping and overturning makes it be conducive to teaching.
In order to solve the above-mentioned technical problem, present invention employs the following technical solutions.
A kind of engine teaching demonstration device, including pedestal, the pedestal, including a horizontally disposed bottom plate, bottom plate
Following four corners is provided with pillar straight down, which is characterized in that it is vertically arranged there are one supporting block on pedestal, supporting block upper end to
Vacantly there are one clamping devices, the clamping device to have the multiple fixture blocks being laterally arranged for setting for preceding side, and fixture block is vertical
On arrange in a ring and surround one front be open end engine holding chamber.
In this way, clamping device can be relied on to grip engine for vacant state, it is made to be more easy to observe lower section
Position, it is convenient that explanation operation is carried out to student.Meanwhile understructure has simple in structure, the reliable feature of supporting ＆ stablizing.
As an optimization, the clamping device further includes a clamping screw, and clamping screw can laterally slidably run through support
The perforation of a screw rod and face engine holding chamber center on block are arranged, and clamping screw rear end is pierced by supporting block and screw thread
Cooperation be screwed on there are one rear side moving block, rear side moving block can be mounted on branch to vertical rotating by rear side moving block mounting structure
On bracer and rear side moving block mounting structure can be relied on to realize limit in the front-back direction；The spiral shell at clamping screw middle part and supporting block
The clamping screw rotation position limiting structure for limiting clamping screw rotation is provided between bar perforation, clamping screw front end is pierced by branch
Bracer simultaneously forms a lever connecting pin for connecting lever, and each fixture block rear end is respectively fixed and connected with the front end of a lever
It connects, lever middle is hinged on supporting rod front end and forms fulcrum, and support rod rear end is relatively fixed to supporting block, and lever rear portion relies on
Strip hinge hole along the setting of length direction is hinged on lever connecting pin so that the back-and-forth motion of clamping screw can
Lever is driven to be rotated along fulcrum.
In this way, rotation rear side moving block can be relied on, clamping screw is driven to be moved forward and backward, and then lever is driven to turn along fulcrum
It is dynamic, and then fixture block is driven to open or clamp.The clamping that clamping device can be conveniently realized, avoids engine from falling down.And
The mechanism, converts by lever mechanism and leadscrew-nut mechanism and transmits chucking power, one come moving block on rear side of make as power
Input terminal can input smaller power forming larger chucking power, facilitating clamping and clamping.Second is that by the transmission of power and turning
After changing so that the clamped reaction force of engine, which can not be transmitted to rear side moving block, causes its reversion, can reach after clamping
Good self-locking effect avoids engine loosening during explaining from falling.
Further, the clamping screw rotation position limiting structure includes positioned at clamping screw outer surface and screw rod perforation inner wall
Between concave-convex fit structure, concave-convex fit structure along clamping screw axially be arranged.In such manner, it is possible to by the concave-convex fit structure
The rotation of clamping screw is limited, but does not limit the sliding of clamping screw in an axial direction, it is convenient for assembly.
Further, the rear side moving block mounting structure, including a vertically arranged rear side turntable, rear side turntable according to
It is installed in rotation in a corresponding rear side turntable installation cavity of supporting block trailing flank by bearing, rear side turntable front end has
One encloses the radially limit part of evagination and realizes limit in the front-back direction by limit part, and rear side turntable rear end is coaxially fixed
The rear side moving block is set, is outwardly protruded in rear side moving block peripheral side and is provided with rotation bolt, set at rear side disk axes
It is equipped with for the freely through relief hole of clamping screw.
In such manner, it is possible to rely on rear side turntable be better achieved rear side moving block and supporting block between being rotatably connected and
Axial limiting.When working at the same time, it is only necessary to move rotation bolt, you can drive rear side moving block rotation, and then pass through feed screw nut
Cooperation drive clamping screw be moved forward and backward, have many advantages, such as it is simple in structure, it is easy to control fast it is reliable.
As an optimization, further include the axial direction for controlling each fixture block around engine holding chamber axial rotation in clamping device
Rotating device, the axial rotating device include a front side moving block, and front side moving block relies on front side moving block mounting structure
