The sliding guide rail 34 is fixedly installed on the frame 2. The feed platform 38 is slidably connected up and down with the sliding guide rail 34, and the feed platform 38 is fixedly connected to the screw nut 39.

[0037] Designed in this way, the feed motor 31 is used to drive the feed platform 38 to move up and down. Specifically, the feed motor 31 is installed on the upper part of the frame 2, and the ball screw 37 is rotatably installed on one side of the frame 2 through a mounting bracket. The screw nut 39 cooperates with the ball screw 37. The feed motor 31 drives the ball screw 37 to rotate, drives the screw nut 39 to move up and down, and then drives the feed platform 38 to move up and down along the sliding guide rail 34. The feed motor 31 is connected to the input end of the feed reducer 32. The feed reducer 32 is fixed above the frame 2 through a feed reducer flange 33. The ball screw 37 is connected to the output end of the feed reducer 32 through a first coupling 310.

[0038] The specific structure of the hollow rotary platform 312 and the specific structure of the encoder 314 are both prior arts and will not be elaborated here.

[0039] The rotating part of the hollow rotary platform 312 is connected to the output end of the indexing motor 311. When the indexing motor 311 rotates, it drives the rotating part of the hollow rotary platform 312 to rotate. The rotating part of the hollow rotary platform 312 then drives the indexing platform 313 to rotate for indexing movement.

[0040] The rotation angle of the indexing platform 313 is accurately measured by the encoder 314.

[0041] The ball screw 37 and the feed platform 38 are respectively located on both sides of the frame 2, and a through hole is opened on the frame 2 between the ball screw 37 and the feed platform 38. The connection structure between the ball screw 37 and the feed platform 38 is arranged through the through hole.

[0042] The footage and indexing unit 3 further includes a magnetic scale magnetic strip 35 and a magnetic scale reading head 36. The magnetic scale magnetic strip 35 is fixedly installed on the frame 2, and the magnetic scale reading head 36 is fixedly installed on the footage platform 38. Designed in this way, it is used to accurately measure the footage and footage speed of the footage and indexing unit 3.

[0043] The rotary drilling unit 4 includes a rotary motor 41, a torque sensor 446, a multi-shaft coupling 49 and a drill tool 43. The output end of the rotary motor 41 is fixedly connected to the input end of the multi-shaft coupling 49 through the torque sensor 446. The multi-shaft coupling 49 is fixedly installed on the indexing platform 313, and the drill tool 43 is installed at the output end of the multi-shaft coupling 49. Designed in this way, the rotary motor 41 is connected to the input end of the rotary reducer 42. The rotary reducer 42 is fixed on the indexing platform 313 through a rotary reducer flange 44. The torque sensor 446 is connected to the output end of the rotary reducer 42 through a second coupling 45, and the torque sensor 446 is connected to the input end of the multi-shaft coupling 49 through a third coupling 47. The multi-shaft coupling 49 is fixed on the indexing platform 313 through a multi-shaft coupling mounting flange 48.

[0044] When the rotary motor 41 rotates, it drives the output shaft of the rotary reducer 42 to rotate, and transmits the power to the multi-shaft coupling 49 through the second coupling 45, the torque sensor 446 and the third coupling 47. The multi-shaft coupling 49 drives the drill tool 43 to rotate.

[0045] The torque sensor 446 includes a fixed part and a rotating part. The fixed part of the torque sensor 446 is fixedly connected to the indexing platform 313. The two ends of the rotating part of the torque sensor 446 are connected to the output end of the rotary reducer 42 and the input end of the multi-shaft coupling 49 through the second coupling 45 and the third coupling 47, respectively, for measuring the drilling torque.

[0046] The number of drill tools 43 is at least two and the rotation directions are opposite. Designed in this way, the number of drill tools 43 is preferably two. When the number of drill tools 43 is two, the two drill tools 43 rotate in opposite directions to offset the load on the footage and indexing unit 3 caused by the torque generated during drilling. When the number of drill tools 43 is more than two, it is ensured that the rotation directions of the multiple drill tools 43 are different to offset the load on the footage and indexing unit 3 caused by the torque generated during drilling. The distance between the drill tools 43 is adjustable and controllable.

[0047] The probe excitation unit 5 includes a mounting base, a spring support 54, a limit switch 53, and a thermal measurement probe 55. The mounting base is fixedly connected to the indexing platform 313. The thermal measurement probe 55 is mounted on the mounting base through the spring support 54. The limit switch 53 is fixedly installed on the mounting base, and the penetration depth of the thermal measurement probe 55 is controlled by the limit switch 53. With such a design, the spring support 54 and the limit switch 53 form a flexible penetration assembly. The penetration force of the thermal measurement probe 55 is balanced by the spring support 54 to ensure that the thermal measurement probe 55 flexibly penetrates into the drill hole formed by the drill tool 43. The penetration depth of the thermal measurement probe 55 is controlled by the limit switch 53 to prevent the contact force from exceeding the limit.

[0048] The mounting base includes a gear box 57, two distance-adjusting gears (51) that rotate and mesh with each other inside the gear box 57, and two rotating disks 52 located outside the gear box 57 and coaxially fixedly connected to the two distance-adjusting gears (51) correspondingly. The number of thermal measurement probes 55 is two, and they are respectively mounted on the two rotating disks 52 through the two spring supports 54. The two thermal measurement probes 55 are symmetrically arranged with respect to the plane where the meshing line of the two distance-adjusting gears (51) is located. The two limit switches 53 are respectively fixedly connected to the two rotating disks 52. With such a design, the gear box 57 is fixedly installed on the indexing platform 313. The two ends of each distance-adjusting gear (51) are respectively connected to the gear box 57 through bearings. When any one of the distance-adjusting gears (51) rotates, the other distance-adjusting gear (51) will rotate in the opposite direction by the same angle, thereby changing the distance between the two thermal measurement probes 55. The distance between the two thermal measurement probes 55 can be adjusted and controlled through the mounting base, which is convenient for corresponding to the drill hole. When the distance between the two thermal measurement probes 55 is close to the distance between the two drill holes, automatic alignment can be achieved. When the difference is large, the two thermal measurement probes 55 can be manually toggled to adjust the meshing position of the two distance-adjusting gears (51).

[0049] The clamping and drilling pressure detection unit 6 includes a self-centering vise 61, an upper connecting frame 62, a six-axis force sensor 63, and a lower connecting plate 64 that are fixedly connected in sequence from top to bottom. The lower connecting plate 64 is fixedly connected to the base 1. With such a design, the self-centering vise 61 is used for clamping and supporting the product. Through the self-centering vise 61, the requirements for the shape and surface accuracy of the product to be measured can be reduced. The axes of the self-centering vise 61 and the six-axis force sensor 63 coincide. When the self-centering vise 61 clamps products of different sizes, the working center remains unchanged, which can reduce the complexity of the device. The six-axis force sensor 63 is used for detecting the drilling pressure received by the product.

[0050] The rotary drilling unit 4 further includes a protective cover 410. The protective cover 410 is fixedly connected to the indexing platform 313 and covers the torque sensor 446. With such a design, it plays a role in protecting the internal torque sensor 446 and each circuit.

[0051] A measuring method for the force and thermal characteristics of the above-mentioned lunar soil forming product measuring device. Place the product to be measured on the clamping and drilling pressure detection unit 6 and lock it. Control the rotary drilling unit 4 to move downward through the feed and indexing unit 3 to drill into the product to be tested, and record the drilling parameters for mechanical property inversion;

[0052] After the mechanical measurement is completed, the rotary drilling unit 4 stops operating. Control the rotary drilling unit 4 to move upward to a specified position through the feed and indexing unit 3, and then control the rotary drilling unit 4 and the probe excitation unit 5 to perform an indexing movement. When the probe excitation unit 5 rotates to directly above the product to be measured, the indexing ends;

[0053] After the indexing is completed, control the probe excitation unit 5 to move downward through the feed and indexing unit 3 for thermal measurement;

[0054] After the thermal measurement is completed, control the probe excitation unit 5 to move upward to a specified position through the feed and indexing unit 3, and then control the rotary drilling unit 4 and the probe excitation unit 5 to perform an indexing movement to return to the initial state and end the measurement.

[0055] The initial state is the position state of the rotary drilling unit 4 and the probe excitation unit 5 before the mechanical measurement.

[0056] Taking the number of drill tools 43 and thermal measurement probes 55 both being two as an example:

[0057] When measuring the mechanical properties of the product to be measured, place the product to be measured above the self-centering vise 61 and lock it. Then drive the ball screw 37 to rotate through the feed motor 31. The ball screw 37 will drive the screw nut 39 to move downward, and the screw nut 39 will drive the rotary drilling unit 4 to move downward. After the drill tool 43 approaches the surface of the product, the rotary motor 41 drives the two drill tools 43 to move in the reverse direction at a set speed through the multi-shaft coupling 49 to drill into the product to be tested;

[0058] After the mechanical measurement is completed, the feed motor 31 moves in the reverse direction and drives the screw nut 39 to move upward through the ball screw 37, and then drives the rotary drilling unit 4 to move upward, and the rotary motor 41 stops rotating. After moving upward to a specified position, the indexing motor 311 rotates, driving the rotating part of the hollow rotary platform 312 to rotate. The rotating part of the hollow rotary platform 312 drives the indexing platform 313 to rotate, thereby driving the rotary drilling unit 4 and the probe excitation unit 5 to rotate for an indexing movement. When the probe excitation unit 5 moves to directly above the product, the indexing ends;

[0059] After the indexing is completed, the feed motor 31 drives the ball screw 37 to rotate, driving the probe excitation unit 5 to move downward, and inserting the thermal measurement probe 55 into the drilled hole for thermal property measurement;

[0060] After the measurement is completed, the feeding and indexing unit 3 drives the ball screw 37 to rotate, driving the rotary drilling unit 4 and the probe excitation unit 5 to move upward to the specified position. The indexing motor 311 drives the rotating part of the hollow rotary platform 312 to rotate, driving the rotary drilling unit 4 and the probe excitation unit 5 to rotate and return to the initial state, ending the measurement.

[0061] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
