Description
Technical field
The invention belongs to superhard material impact resistance sensing equipment technical field, particularly a kind of diamond compact impact test device of measuring the oil and natural gas probing with the diamond compact toughness.
Background technology
At present, diamond compact (PDC) in bur, obtained using widely, but its impact flexibility is relatively poor with its good anti-wear performance.In recent years, people are devoted to improve the shock resistance characteristic of diamond compact, in the rock crushing tool (like the pick tooth) of seeking to be applied to contain impact.But, because the detection means of diamond compact impact resistance is very backward, cause the state of diamond compact when the virtual condition of underground work is tested with toughness to differ bigger, seriously fettering research to the diamond compact impact property.
Summary of the invention
The invention provides a kind of simple in structure, easy and simple to handle, automaticity is high and precision is high diamond compact impact test device.
For realizing above-mentioned purpose, technical scheme of the present invention is: a kind of diamond compact impact test device, comprise guide pillar and the top board and the base plate that are fixed on the guide pillar two ends, and top board is provided with cylinder, and base plate is provided with anchor clamps; The piston rod front end of cylinder is provided with air spider, is equipped with in the air spider and drops hammer, and it is corresponding with anchor clamps to drop hammer, and the front end that drops hammer is provided with towards ball.
Said guide pillar is provided with the moving plate that is slidingly matched with it, and moving plate top is provided with the connection support, connects support and links to each other with the piston rod of cylinder; In connecting support, be provided with stepper motor, stepper motor links to each other with air spider through output shaft, and air spider passes through Bearing Installation in moving plate bottom.
The said guide pillar corresponding guide plate that is provided with and drops hammer.
Said top board is provided with the induction travel switch.
Said base plate is provided with force transducer and displacement transducer.
Compared with prior art, advantage of the present invention is:
1, the present invention includes guide pillar and be fixed on the top board and the base plate at guide pillar two ends, top board is provided with cylinder, and base plate is provided with anchor clamps; The piston rod front end of cylinder is provided with air spider, is equipped with in the air spider and drops hammer, and it is corresponding with anchor clamps to drop hammer; The front end that drops hammer is provided with towards ball, and it is simple in structure, and is easy and simple to handle; Utilize the percussion drilling wave theory, the actual forced status of simulation diamond compact when underground work makes towards ball and dashes the marginal portion of pounding diamond compact one by one; When visible crack occurring or producing fragmentation with specimen surface; Obtain impact toughness value as the quantitative target of weighing its impact resistance, automaticity is high, and it is high to measure precision.
2, the corresponding guide plate that on guide pillar, is provided with and drops hammer, guide plate dropping hammer when falling play the guiding role, and can guarantee the whereabouts precision of dropping hammer, and improves the mensuration precision of diamond compact impact resistance.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
Diamond compact impact test device as shown in Figure 1, it comprises guide pillar 2 and top board that is fixed on guide pillar two ends about in the of 23 and base plate 1, is provided with cylinder 9 in the central upper portion position of top board 3, base plate 1 is provided with anchor clamps 8.On guide pillar 2, be provided with the moving plate 4 that is slidingly matched with it, moving plate 4 tops are provided with and connect support 10, connect support 10 and link to each other with the piston rod of cylinder 9.In connecting support 10, be provided with stepper motor 11, stepper motor 11 links to each other with the air spider 5 of moving plate 4 bottoms through output shaft, and air spider 5 is installed in moving plate 4 bottoms through bearing 12.In air spider 5, be equipped with and drop hammer 6, it is 6 corresponding with anchor clamps 8 to drop hammer, be provided with towards ball 7 at 6 front ends that drop hammer, and be that wimet is towards ball towards ball 7.
In order to guarantee to drop hammer 6 whereabouts precision, the 6 corresponding guide plates 14 that on guide pillar 2, are provided with and drop hammer, dropping hammer when 14 pairs of guide plates fall 6 play the guiding role.
Be provided with induction travel switch 13 in top board 3 one sides, base plate 1 is provided with force transducer 16 and displacement transducer 17.
In this embodiment, constitute control system by pneumatic control circuit, control circuit, amplifier and servo-drive, man-machine interface is set and PLC controls the impulse test that realizes diamond compact automatically through touching.
Principle of work of the present invention is: utilize the percussion drilling wave theory; The actual forced status of simulation diamond compact (calling PDC in the following text) when underground work; Make towards ball 7 and dash the marginal portion of pounding PDC one by one; When visible crack occurring or producing fragmentation, obtain impact toughness value as the quantitative target of weighing its impact resistance with specimen surface.Simultaneously; But highly sensitive force transducer 16 is with displacement transducer 17 detail record impact processes, contact force of the breath and merit change procedure in time towards ball 7 with diamond layer; Microcosmic force-bearing situation and ruined time point when impacting with reflection provide important references information to research PDC impact property.According to varying in size of survey PDC, different impact energys can be set.
Use of the present invention is: and cylinder 9 drives moving plate 4 and air spider 5 descending → air spiders 5 and clamps the 6 → cylinder 9 that drops hammer and drive moving plate 4 up certain altitudes and stop → and stepper motor 11 drives air spiders 5 and the 6 rotation 12 ° → air spiders 5 that drop hammer unclamp and drop hammer 6; The ball 7 that dashes of 6 free-fallings → drop hammer 6 of dropping hammer dashes the marginal portion of pounding sample 15 (be the glomerocryst layer of diamond compact with vertically be 15 ° of parts), and above-mentioned action circulates.Dashing the marginal portion of pounding sample 15 towards ball 7 is the position of stressed maximum on the drill body, can guarantee that test is consistent with actual forced status.
