As shown in Fig. 2 is to 5, the lower surface of switching bottom 1 has first counter sink 101 corresponding with first boss 301, And first boss 301 falls into the first countersunk head in the hole 101;The upper surface of switching bottom 1 has multiple three fixations of annular array Hole 102, and having the second counter sink 103 with the corresponding position of the first counter sink 101, the first connecting bolt is sunk through second Head bore 103 and the first counter sink 101 are fixed on the first of vibration table 3 and fix in the hole.
As shown in Fig. 6 to 9, the lower surface on switching top 2 is provided with and the corresponding second boss 201 of the second counter sink 103, and Second boss 201 falls in the second counter sink 103;The upper surface on switching top 2 has and the 3rd fixing hole 102 the corresponding 3rd Counter sink 202, the second connecting bolt fixes 102 in the holes through the 3rd counter sink 202 is fixed on switching bottom 1 the 3rd, switching The upper surface on top 2 has fourth fixing hole 203 corresponding with the second fixing hole of additional mesa 401, the 3rd connection simultaneously Bolt passes through the second fixing hole of additional mesa 401 to be fixed in the 4th fixing hole 203, and wherein, all of fixing hole is spiral shell Pit.
Existing synthetic experiment equipment is that the bottom of temperature test chamber is in sustained height, by additional stations with vibration table top Face 401 is fixed with 16 boss of vibration table, and the synthetic experiment equipment switching device that this utility model provides is for working as There is the situation of difference in height in temperature test chamber bottom and vibration table top.
When installing this switching device, switching bottom 1 is placed on vibration table 3 upper surface (as Fig. 1), mobile switching bottom is arrived The position of first boss 301, and fine rotation until 16 first boss 301 each fall within switching bottom 1 the first countersunk head in the hole In 101, described first connecting bolt is passed through the second counter sink 103 and the first counter sink 101 to be fixed on the first of vibration table 3 and consolidate Determine in the hole, that is, complete bottom 1 location and installation of transferring.
Then, as shown in Figure 10, switching top 2 is placed on switching bottom 1, mobile and fine rotation switching top 2 makes Align in remaining switching bottom 1, the second boss 201 on switching top 2 each falls within the second counter sink 103 of switching bottom 1 simultaneously, As shown in figure 11 the second connecting bolt (not indicating in figure) is fixed on the 3rd of switching bottom 1 through the 3rd counter sink 202 Fix 102 in the holes, that is, complete top positioning 2 installation of transferring.
Finally, the second fixing hole the 3rd connecting bolt being passed through additional mesa 401 fixes (not in figure indicate) the In four fixing holes 203, complete to test the installation of switching device.
By switching device is designed as upper and lower two parts, installed respectively, alleviated the work of the staff of installation Industry intensity, is designed to the structure of the boss and counter sink cooperating simultaneously, is easy to be positioned when switching device is installed, reduces Installation difficulty, convenient and swift.
Wherein, the first counter sink 101 is different from the second counter sink 103 depth, and lower surface the first counter sink 101 depth are little, Effect is positioning, and upper surface the second counter sink 103 depth is big, and effect is to install connecting bolt.
Wherein, the number of first boss 301 generally 16, inside and outside two circles each 8 are annularly distributed, the therefore first counter sink 101 number be 16 correspond with first boss 301 it is preferred that the number of the second counter sink 103 be 16 with first sink Head bore 101 corresponds and communicates.
Accordingly preferred, the number of the 3rd fixing hole 102 is 16, inside and outside each 8 distributions annular in shape of two circles, wherein, often Individual 3rd fixing hole 102 is interspersed between two the second counter sinks 103;The number of the 3rd fixing hole 102 can also be 8, Every being interspersed between 16 the second counter sinks 103.
In a practical situation, the second counter sink 103 can also be set as 8, and inside and outside two enclose each 4, heavy with 16 first Head bore 101 interval corresponds to, and the number of corresponding three fixing holes 102 is 8, and each 8 of inside and outside two circle is annularly evenly distributed interspersed Between 8 the second counter sinks 103.
3rd fixing hole 102 is interspersed in the structure between two the second counter sinks 103, makes switching top 2 and switching bottom 1 Uniform force after installation, switching top 2 and switching bottom 1 junction when preventing switching device from can constantly shake in use Unbalance stress causes local damage.
Preferably, switching bottom 1 has the first central through hole 104, and switching top 2 has the second central through hole 204.
On the premise of not affecting allomeric function, the structure that hollow is made in switching bottom 1 and switching top 2 contributes to subtracting The overall weight of light industry part, facilitates staff to be installed.
Preferably, the diameter of the first central through hole 104 of switching bottom 1 is less than second central through hole 204 on switching top 2 Diameter, and the upper surface of bottom 1 of transferring raises up an annular boss 105 along the inwall of the first central through hole 104, convex annular The internal diameter of the external diameter of platform 105 and the second central through hole 204 is adapted, and the external diameter of annular boss 105 is slightly smaller than the second central through hole 204 internal diameter is it is ensured that switching top 2 can be set on the annular boss 105 of switching bottom 1.
In the first central through hole 104 increase by annular boss 105 upwards of switching bottom 1, for installing switching top 2 When it is only necessary to by switching top 2 the second central through hole 204 be aligned switching bottom 1 the first central through hole 104, make convex annular Platform 105 falls into the second central through hole 204 and can easily position, and then somewhat rotates switching top 2 and all falls until second boss 201 Enter to transfer bottom 1 the second counter sink 103 in just complete transfer top installation, by increase annular boss 105, make to install The faster convenience of journey.
Preferably, the outside circumference on switching bottom 1 and switching top 2 is provided with symmetrical handle (not indicating) in figure; By arranging symmetrical handle, staff is facilitated to be carried when this switching device is installed.
