[0030] The present invention provides a mechanical property detection device, comprising a workpiece mounting seat 1 having a mounting platform and a loading mechanism 2 having a static load loader 3 and / or an impact load loader.

[0031] In this embodiment, the workpiece mounting seat 1 is provided with a mounting platform, and the mounting platform is used to clamp the workpiece 01 and drive the workpiece 01 to move. The mounting platform realizes the angle adjustment and / or position adjustment of the workpiece 01 at the clamping station by driving the workpiece 01 to move. The loading mechanism 2 is arranged on one side of the workpiece mounting seat 1, and the static load loader 3 and / or impact load loader of the loading mechanism 2 are adjacent to the mounting platform, and are used to apply a static load or an impact load to the workpiece 01 clamped on the mounting platform. Obviously, the static load loader 3 is used to apply a static load to the workpiece 01, and the impact load loader is used to apply an impact load to the workpiece 01. The mechanical property detection device can be provided with one or more of the static load loader 3 and the impact load loader according to the test requirements of the workpiece 01 to be detected.

[0032] The mechanical property detection device provided by the present invention can be used for mechanical property detection of a meter box, for example, for detecting a static load resistance test, a horn-shaped mechanical impact resistance test, an impact load resistance test and an impact force resistance test of the meter box.

[0033] As for the detection result of the workpiece 01 after the load is loaded, it can be set according to the specific detection content of different workpieces, including but not limited to direct observation by the inspector through the naked eye, measurement with the help of detection tools, etc.

[0034] In summary, the mechanical property testing device provided by the present invention utilizes the workpiece mounting platform and the loading mechanism 2 to realize the automation of the clamping, position adjustment and test operation of the workpiece 01 in the detection test, which can meet the test requirements of the same workpiece 01 or different workpieces 01 in the mechanical property detection test, greatly improve the test efficiency, reduce the manpower consumption during the test process, and improve the test safety.

[0035] The mechanical property detection device provided by the present invention is further described below in conjunction with the accompanying drawings and implementation modes.

[0036] The mechanical property testing device provided by the present invention may include a rotating platform and a fixture mounted on the rotating platform. The fixture is mounted on the rotating platform, and when the rotating platform rotates, the fixture is driven to rotate synchronously, thereby realizing the rotation of the workpiece 01.

[0037] The structure of the fixture can be specifically set according to the structural dimensions of the workpiece 01 to be detected. Taking the workpiece 01 to be detected as a meter box as an example, the meter box is roughly in the shape of a rectangular parallelepiped, and the fixture can use claws to clamp the opposite side surfaces of the meter box, and can also use negative pressure or electromagnetic adsorption to adsorb one of the surfaces of the meter box. In each embodiment provided by the present invention, the fixture preferably uses the former as the clamping method.

[0038] The rotating table is used to rotate the fixture and the workpiece 01 clamped therein. According to the inspection requirements of the workpiece 01 to be inspected, the rotating table can drive the workpiece 01 to adjust its angle by rotating the fixed axis, etc., so that the static load loader 3 and / or the impact load loader of the loading mechanism 2 can apply loads to different positions of the workpiece 01.

[0039] Exemplarily, the rotating table may include a first rotating table 5 for driving the workpiece 01 to rotate around a first rotating axis and a second rotating table 6 for driving the workpiece 01 to rotate around a second rotating axis. The first rotating table 5 and the second rotating table 6 are connected to each other so that the rotating table drives the workpiece 01 to rotate around different directions. In simple terms, the second rotating table 6 can be installed on the first rotating table 5. When the second rotating table 6 is fixed, the workpiece 01 can be driven to rotate around the first rotating axis through the first rotating table 5; when the first rotating table 5 is fixed, the workpiece 01 can be driven to rotate around the second rotating axis through the second rotating table 6. When the first rotating table 5 and the second rotating table 6 are turned on at the same time, the workpiece 01 can rotate toward multiple angles.

[0040] Considering the actual operation, in the rotating table used in the present invention, the first rotating axis of the first rotating table 5 and the second rotating axis of the second rotating table 6 are located in the same plane and are perpendicular to each other. Figure 2 The first rotation axis of the first rotating table 5 is horizontal and distributed along the inside-outside direction of the paper; the second rotation axis of the second rotating table 6 is horizontal and distributed along the left-right direction as shown in the figure. Therefore, the workpiece 01 clamped by the rotating table can be flipped in the inside-outside direction of the paper and rotated clockwise or counterclockwise as shown in the figure.

[0041] As for the clamping function of the fixture on the workpiece 01, it can be achieved through the clamping claws 7. For example, the fixture includes multiple clamping claws 7 for synchronously approaching and moving away from the clamping center; wherein the clamping center refers to the central position of all the clamping claws 7 in the moving direction in the fixture, and the clamping center is located on the rotating axis of the rotating table. Based on this structure, when the fixture clamps workpieces 01 of different sizes, it can always ensure that the center of the workpiece 01 is located at the clamping center of the fixture; when the fixture rotates under the action of the rotating table, it can always ensure that the center of the workpiece 01 is fixed, which is convenient for positioning the workpiece 01.

[0042] The following provides a specific structural setting of the clamp. The clamp includes a transverse lead screw 8 with a clamping claw 7 and a longitudinal lead screw 9 with a clamping claw 7. The clamping claw 7 of the transverse lead screw 8 is installed at both ends of the transverse lead screw 8 through a lead screw nut. Similarly, the clamping claw 7 of the longitudinal lead screw 9 is installed at both ends of the longitudinal lead screw 9 through a lead screw nut. When the clamping claws 7 at both ends of the transverse lead screw 8 move toward each other, they can clamp the workpiece 01 located in the middle of the transverse lead screw 8. Conversely, when they move away from each other, they can loosen the workpiece 01 located in the center of the transverse lead screw 8. Similarly, the longitudinal lead screw 9 achieves the clamping and loosening of the workpiece 01 through the clamping claws 7 at both ends.

[0043] In addition, an interactive operation synchronization component 10 is also provided between the transverse screw 8 and the longitudinal screw 9. The interactive operation synchronization component 10 can be installed at the length center of the transverse screw 8 and the length center of the longitudinal screw 9, and the rotation ratio of the transverse screw 8 and the longitudinal screw 9 is constrained by the thread provided in the interactive operation synchronization component 10. For example, when the transverse screw 8 rotates a pitch, the longitudinal screw 9 rotates a preset pitch under the constraint of the interactive operation synchronization component 10, and the preset pitch can be equal to a pitch of the transverse screw 8, or can be greater than or less than a horizontal pitch of the transverse screw 8. Of course, the interactive operation synchronization component 10 can also realize the motion relationship between the transverse screw 8 and the longitudinal screw 9 by constraining the power device driving the transverse screw 8 and the power device driving the longitudinal screw 9.

[0044] In order to achieve better technical effects, in the mechanical property testing device provided by the present invention, the workpiece mounting seat 1 also includes a first slide rail 11 slidably connected to the rotating table and used to drive the rotating table to approach and move away from the loading mechanism 2.

[0045] The first slide rail 11 can be installed below the rotating table, and the rotating table slides along the first slide rail 11 to move the workpiece 01 away from the loading mechanism 2 or the workpiece 01 closer to the loading mechanism 2. Figure 4 and Figure 6 , Figure 4 The first slide rail 11 is used to be installed under the rotating table to drive the rotating table and the workpiece 01 mounted on the rotating table to move along the rotating table. Figure 4 Move in the left and right directions as shown; Figure 6 In the process, the first slide rail 11 is along Figure 6 The left and right directions shown are used to drive the rotating table along Figure 6 Move left and right as shown.

[0046] The loading mechanism 2 adopted in the present invention includes a static load loader 3 and an impact load loader, and both the static load loader 3 and the impact load loader are longitudinally slidably connected to the bracket 12, so as to facilitate the adjustment of the loading position of the static load loader 3 on the workpiece 01 and the loading position of the impact load loader on the workpiece 01.

[0047] In the loading mechanism 2 , both the static load loader 3 and the impact load loader include a loading head and a driving device for driving the loading head to move.

[0048] For reference Figure 5 and Figure 6 The loading head of the static load loader 3 is installed longitudinally downward through the bracket 12, and the driving device of the static load loader 3 drives the loading head to move longitudinally downward, so that the loading head continuously applies a constant force to the workpiece 01 to realize static load loading.

[0049] For the mechanical property detection device applied to the meter box, the impact load loader can specifically adopt a pendulum structure, that is, the loading head of the impact load recorder is specifically a pendulum 20 with a striking body 19 at the end.

[0050] The pendulum 20 swings and strikes the workpiece 01, thereby applying an impact load to the meter box. Accordingly, the driving device of the impact load loader is specifically a reset rod 21 for driving the pendulum 20 to rotate to achieve reset. The fixed end of the pendulum 20 can achieve longitudinal sliding relative to the bracket 12 through the second slide rail 24.

[0051] After the pendulum 20 swings downward each time, the reset rod 21 drives the pendulum 20 back to the initial position to facilitate the next operation. Figure 5 As shown, a first limit rod 22 for limiting the reset height of the pendulum 20 in the impact load resistance test and the impact force resistance test of the meter box and a second limit rod 23 for limiting the reset height of the pendulum 20 in the horn impact resistance test of the meter box are provided.

[0052] The striking body 19 is an iron pointed hammer, an iron ball or an iron block. Taking the workpiece 01 to be tested as a meter box as an example, the iron pointed hammer can realize the mechanical impact test of the meter box against angular objects by striking the meter box; the iron ball can realize the impact load test of the meter box by striking the meter box; and the iron block can realize the impact force test of the meter box by striking the meter box. It can be seen that the specific structure of the striking body 19 depends on the test requirements of the workpiece 01.

[0053] In order to facilitate the knocking body 19 to apply load to the workpiece 01, in the above embodiment, the reset rod 21 of the impact load loader includes an adsorption head and a rotating motor. The adsorption head is used to adsorb the knocking body 19 to achieve relative fixation with the knocking body 19; the rotating motor is used to drive the adsorption head to rotate at a preset angle to increase the gravitational potential energy of the knocking body 19, so as to facilitate the knocking body 19 to hit the workpiece 01 in the form of a swinging motion. Based on the motion relationship between the knocking body 19 and the workpiece 01, the process of the knocking body 19 being driven by the reset rod 21 to achieve rotation can be regarded as the reset process of the knocking body 19. The knocking body 19 increases its own gravitational potential energy through reset in preparation for the next swing.

[0054] The adsorption head can be fixedly connected to the striking body 19 by vacuum adsorption or magnetic adsorption. Based on the above embodiment, the striking body 19 is specifically configured as an iron pointed hammer, an iron ball and an iron block, and the adsorption head can be relatively fixed to the adsorption head and the striking body 19 by electromagnetic adsorption.

[0055] For the convenience of operation, the mechanical property detection device further includes a box body 13 arranged on the periphery of the workpiece mounting seat 1 and the loading mechanism 2 . In other words, the workpiece mounting seat 1 and the loading mechanism 2 are both installed in the box body 13 .

[0056] The surface of the box 13 is provided with an operation interface 14 and a protective door 15. The operation interface 14 is connected to the workpiece mounting seat 1 and the loading mechanism 2 in the box 13, and is used to open, close and control the workpiece mounting seat 1 and the loading mechanism 2. For example, the operation interface 14 includes a switch for connecting to a driving device of a static load loader 3 of the loading mechanism 2. The protective door 15 can ensure the safety of the test personnel during the test, and can also serve as an entrance and exit for personnel to enter and exit, and for the clamping and removal of the workpiece 01. In addition, the chassis cover 18 of the box 13 can also be used as an entrance and exit channel for personnel to inspect and replace test equipment and an entrance and exit channel for the workpiece 01. For example, the rear cover of the chassis is used for personnel to enter and exit, and the front cover of the chassis is used for the entry and exit of the workpiece 01.

[0057] A display module 17 may also be provided on the surface of the box body 13 , including but not limited to a display screen or an indicator light, which plays a role in displaying the operating status of the workpiece mounting seat 1 and the loading mechanism 2 .

[0058] The box 13 is provided with a detector 16 for obtaining the structural performance change of the workpiece 01. Taking the workpiece 01 to be detected as a meter box as an example, the static load resistance test of the meter box needs to detect the damage degree of the box 13 of the meter box under the static load, including but not limited to calibrating the damage degree of the meter box through parameters such as the deformation amount of the surface of the box 13 and the damage form of the local damaged area.

[0059] The mechanical property detection device applied to the meter box can specifically use a camera as the detector 16 to capture image information of the surface of the meter box body 13 before and after loading. Of course, depending on the workpiece 01 to be detected, the detector 16 can also be set as other detection elements such as a stress sensor.

[0060] In summary, the mechanical property detection device provided by the present invention realizes automatic clamping of the workpiece 01 through the workpiece mounting seat 1, realizes automatic adjustment of the installation position and the test position of the workpiece 01, meets the clamping requirements of different tests, greatly improves the test efficiency, and reduces the manpower consumption during the test process; automatically loads static loads and / or impact loads to the workpiece 01 through the loading mechanism 2 to meet the test operation requirements of different tests; realizes the overall movement of the workpiece mounting seat 1 and the workpiece 01 clamped therein relative to the loading mechanism 2 through the first slide rail 11, facilitates the test personnel to install and disassemble the workpiece 01, ensures the safety of personnel during the installation process, and improves the efficiency of the overall test process.

[0061] In addition, the box 13 of the mechanical property detection device can be used to protect the safety of the test personnel during the test process, and facilitate the test personnel to operate and monitor the operating status of the workpiece mounting seat 1 and the loading mechanism 2 in the box 13. The detector 16 arranged in the box 13 can monitor the test process in real time, assist in manual determination of the test results, greatly improve the safety of personnel and the test efficiency during the test process, and greatly reduce the manpower consumption during the test process. Based on the box 13, the mechanical property detection device can also realize remote operation and control, and improve the safety of personnel by keeping the test personnel away from the box 13 during the test process, which is convenient for future docking with the automated detection line.

Specific examples are used in this article to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the method of the present invention and its core idea. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the present invention, several improvements and modifications can be made to the present invention, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
