Row cutting stroke.
It follows that the effect of the First terrace 12 on limit rope 16 and limited block 6 in the present embodiment is determining
The maximum downstream of saw blade 5 cuts stroke.Although as 5 downlink of saw blade, the vertical uplink of balancing pole 15 and continuous draw springs
14,14 elongation of elastic component increases and increases the pulling force to balancing pole 15, but elastic component 14 can not provide stable binding character
Pulling force, if external force overcomes the elastic force of elastic component 14 to continue to rotate rotation axis 3 counterclockwise, saw blade 5 can continue downlink and cut
There is the possibility for cutting bad sample stage 8 after cutting sample.And the moment being straightened in limit rope 16 generates pulling force to balancing pole 15, steadily
The no longer uplink of confined equilibrium bar 15 (i.e. the no longer downlink of saw blade 5)；First terrace 12 and limit card slot 11 on limited block 6
First scuff-resistant coating 13 of left side edge offsets, so that reaching range inter-axle shaft 3 in saw blade 5 can not rotate counterclockwise.Cause
This, the maximum downstream that the present embodiment limits saw blade 5 by both modes simultaneously cuts stroke.
B. after saw blade 5 reaches maximum downstream cutting stroke, the second motor 17 drives transmission shaft 3 clockwise around its axis center
Rotation, and drive saw blade 5 and first motor 4 to rotate clockwise in turn, lifting for saw blade 5 is shown as on vertical, when transmission shaft 3
On stop arm 25 rotation to touching support be set to supporting element 2 on fixation spacer pin 26 (27)；At the same time, on limited block 6
Also (right side herein is the right side in Fig. 2 on 11 right side of limit card slot of the touching simultaneously to limit card slot supporting element 7 in second step face 31
Side) edge the second scuff-resistant coating 32；Both the above mode limits the terminal rotated clockwise of transmission shaft 3 simultaneously, and at this time first
Motor 4 and saw blade 5 reach highest order.
Structure in the present embodiment solves the problems, such as some other.Such as: highest is in first motor 4 and saw blade 5
When position, since there are self gravity first motors 4 and saw blade 5 to have downlink trend, at this moment, by elastic component 14 to balancing pole 15
Draw can reach balance with the gravity of first motor 4 and saw blade 5.In the entire mistake that first motor 4 and saw blade 5 move
Cheng Zhong, elastic component 14 generate the state of pulling force in elongation always.When first motor 4 and saw blade 5 are located at highest point, elastic component
14 pulling force only needs to overcome the gravity of first motor 4 and saw blade 5.In 4 downlink of saw blade, in addition to above-mentioned gravity, elastic component 14
It also needs to overcome the extraneous rotatory force given.Under normal circumstances, after first motor 4 and saw blade 5 peak, operator at this time
The operation of replacement sample 9 need to be carried out, such operation generally comprises unloading cutting sample, changes new sample to be cut, Gu
Fixed new sample to be cut, and prepare several programs such as cutting；This process needs a few minutes clock time under normal circumstances, and
Operator's upper body and arm are exposed under saw blade in this operating process.If only the elastic force of flexible part 14 balances
The gravity of first motor 4 and saw blade 5, since the elastic force is a kind of unstable restraining force, if equipment is by extraneous unexpected
Vibration, be such as not intended to touching, situations such as falling object is hit or system by sharp pounding elastic component elastic force unstability, first motor 4
There is a possibility that unexpected downlink with saw blade 5, to jeopardize the operator for replacing sample under first motor 4 and saw blade 5.For gram
The gravity of first motor 4 and saw blade 5 when reaching highest order is taken, applies to first motor 4, saw blade 5 and its transmission mechanism and stablizes
Downlink limit constraint so that first motor 4 and saw blade 5 before artificial constraint relief in stablizing limit state, can not under
Row, can be used structure as shown in Figure 3, dismountable movable spacer pin 28 be arranged on supporting element 2, in first motor 4 and saw
After piece 5 reaches highest order, movable spacer pin 28 is connected on supporting element 2, the stop arm connecting with transmission shaft 3 is thus defined
25 scope of activities.Movable spacer pin 28 provides stable restraining force, to define the rotation counterclockwise i.e. the of transmission shaft 3
The downlink of one motor 4 and saw blade 5, it is ensured that operator replaces safety when sample.After replacing sample, movable spacer pin is unloaded
28, start the rotary switch counterclockwise of the second motor 17, driving transmission shaft 3 can rotate counterclockwise to carry out cutting operation again.
Other than using the scheme of movable spacer pin 28, there are also other schemes can prevent first motor 4 and saw blade
The accident downlink when being located at highest order, such as a support rod can be set in first motor 4 and its transmission mechanism and (do not shown in figure
Out), and the switch of peripheral hardware one is used to control support rod, when first motor 4 and saw blade 5 run to highest order, and needs to prevent it
When unexpected downlink, by the control switch of lower support bar, support rod meeting automatic spring limits first motor 4 and 5 downlink of saw blade, when
When fixing preparation of samples cutting, support rod control switch is pressed again, support rod can automatically retract, and support rod is made to be unlikely to hinder
Block saw blade downlink cutting sample.Such as the hole that support rod can be inserted can be reserved on foundation of incision machine 1, exist in support rod
It is inserted into hole when pop-up, so that first motor 4 and saw blade 5 are static with respect to foundation of incision machine 1, they sup-port first
Motor 4 and saw blade 5 prevent its unexpected downlink.
In addition, since saw blade is generally metal structure, when saw blade cuts rock sample, since rubbing action can generate greatly
Calorimetric amount needs to prevent saw blade from overheating with the cooling saw blade of coolant liquid.To guarantee safety when 5 off working state of saw blade, and prevent
