Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
Referring to fig. 1, the utility model discloses a compression testing machine, including frame 1, the briquetting 2 that moves of setting in frame 1, frame 1 below is equipped with operation panel 6, quiet briquetting 3 is installed on operation panel 6, and operation panel 6 is opened all around has backplate groove 5 (see fig. 2), has guard plate 4 along its direction of height sliding connection in backplate groove 5, and backplate groove 5 still is equipped with lift groove 13 (see fig. 2) along its direction of height, is equipped with the elevating system who is connected and control guard plate 4 and remove with guard plate 4 in the lift groove 13.
Referring to fig. 2, the lifting mechanism includes a screw 7, a nut block 8 screwed on the screw 7, a fixing base 11 rotatably connected to one end of the screw 7, and a motor 12 coaxially rotatably connected to the other end of the screw 7. The fixed seat 11 and the motor 12 are respectively fixedly connected to the side wall of the lifting groove 13. The nut slider 8 is welded with an annular connecting plate 9, and the other end of the connecting plate 9 is abutted against the lower end of the protection plate 4. When the motor 12 rotates, the screw rod 7 can be driven to rotate, and then the nut sliding block 8 moves to adjust the height positions of the connecting plate 9 and the protection plate 4.
When the protection plate 4 is retracted into the protection plate slot 5, the dust cover 15 will move down to the accommodating slot 16 under the action of gravity, and the torsion spring 17 will be restored to its original shape.
The frame 1 is provided with a sprayer 10 at the end remote from the operating panel and the nozzle of the sprayer 10 is directed towards the work surface of the operating table 6. The sprayer 10 can spray mist to the operation table during operation, and the flying dust generated during the operation of the pressure tester can be removed through the sprayer 10 in an accelerating way.
Referring to fig. 1, the periphery of an operating platform 6 is fixed on a tripod 19 near a rack 1, a high-speed camera 20 is fixed on the tripod 19, a lens of the high-speed camera 20 faces a static pressure block 3, and the high-speed camera 20 can accurately and clearly shoot and record the deformation condition of a test sample in the whole loading and pressing process during working.
The implementation principle of the embodiment is as follows: the lifting mechanism is adjusted so that the protection plate 4 is completely retracted into the protection plate groove 5. The worker test sample was placed on the static pressure block 3. The motor 12 is started, the motor 12 drives the screw rod 7 to rotate, the nut slide block 8 threaded on the screw rod 7 starts to ascend, and the protection plate 4 on the connecting plate 9 is driven to ascend.
As the shield plate 4 is raised, the dust cover 15 is gradually pushed open after receiving the force from the shield plate 4. At this time, the torsion spring 17 connected to the dust cover 15 is in a twisted state, and the cleaning cloth 18 on the end surface of the dust cover 15 is brought into close contact with the surface plate of the protection plate 4 after the protection plate 4 is further lifted. The cleaning cloth 18 is tightly attached to the surface plate of the protection plate 4, so that the protection plate 4 can play a role of automatic cleaning in the lifting process. When the protection plate 4 rises to be abutted against the rack 1, the motor 12 stops rotating, the protection plate 4 is in a protection working state, and the dynamic pressure block 2 of the compression testing machine moves towards the static pressure block 3 and extrudes a test sample.
The scattered crushed stone or flying dust generated when the pressure tester applies a load to the test sample is blocked by the protective plate 4. In order to accelerate the rapid dissipation of the flying dust, the sprayer 10 is then turned on, and the mist water molecules sprayed by the sprayer 10 are fully mixed with the flying dust, so that the flying dust in the air can be effectively dissipated.
The high-speed camera 20 can accurately and clearly shoot and record the deformation and damage conditions of the test sample in the whole loading and pressing process in the test process so as to allow an operator to analyze and record the obtained data.
After the protection plate 4 finishes working, the motor 12 rotates to drive the screw rod 7 to rotate, and further the nut sliding block 8 drives the connecting plate 9 and the protection plate 4 to move downwards. When guard plate 4 one end moves down to contacting with shield 15, shield 15 can be along with moving down of guard plate 4 and constantly be close to holding tank 16 under the effect of gravity and torsional spring 17, until guard plate 4 retracts completely to guard plate groove 5 back torsional spring 17 and resumes deformation.
The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
