[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] The purpose of this invention is to provide a horizontal permanent magnet direct-drive electric drill testing device to solve the problems existing in the prior art and provide an efficient, safe and economical solution for the performance testing of electric drills.

[0040] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0041] like Figures 1 to 6 As shown, this embodiment provides a horizontal permanent magnet direct-drive electric drilling tool testing device for testing the performance of a permanent magnet direct-drive electric drilling tool (including the tested motor 3 and the drill bit 14 detachably connected to the output shaft of the tested motor 3). This testing device simulates actual drilling conditions and load environments to achieve efficient and safe testing of the electric drilling tool. It includes a base 1, a pushing device, a measuring device, a second clamping mechanism 16, and a torque and speed measuring module.

[0042] The base 1 serves as the mounting foundation for the entire device and is fixed to the ground with bolts to ensure stability during the testing process. A horizontal slide rail is installed on the base 1; in this embodiment, an I-beam is used as the slide rail, which has high structural strength and can stably support the sliding and load-bearing of subsequent components. Four first clamping mechanisms 2 are slidably fitted on the slide rail to clamp the motor 3 under test. Through the sliding cooperation between the first clamping mechanisms 2 and the slide rail, the movement of the motor 3 under test during drilling can be accommodated.

[0043] The first clamping mechanism 2 comprises a sliding base 208, a first leveling plate 203, a first pressing unit and a second pressing unit. The sliding base 208 is in sliding fit with the slide rail. In order to reduce the sliding resistance, eight rollers 209 are arranged on the sliding base 208, each roller 209 is in rolling fit with the slide rail, so that the sliding base 208 drives the motor 3 to slide along the slide rail more smoothly. The first leveling plate 203 is connected with the top end of the sliding base 208 through four first adjusting studs 215 which are evenly distributed. Each first adjusting stud 215 is threadedly connected with a first adjusting nut 216 located above the first leveling plate 203 and a second adjusting nut 218 located below the first leveling plate 203. The first leveling plate 203 is sleeved on all the first adjusting studs 215. By adjusting the positions of the first adjusting nut 216 and the second adjusting nut 218 on the first adjusting stud 215, the levelness of the first leveling plate 203 can be adjusted, and then the horizontal posture of the motor 3 under test can be adjusted, so as to ensure the coaxiality of the output shaft of the motor 3 under test and the test related components. The first pressing unit comprises a first upper pressing plate 201 and a first lower pressing plate 202 fixedly connected with the first leveling plate 203. One end of the first upper pressing plate 201 is connected with one end of the first lower pressing plate 202 through a first bolt 217. The other end of the first upper pressing plate 201 is connected with the other end of the first lower pressing plate 202 through a pressing bolt 219. The first upper pressing plate 201 and the first lower pressing plate 202 cooperate to clamp the motor 3 under test in the vertical direction, so as to realize the preliminary fixation of the motor 3 under test. The second pressing unit comprises a support base, a chain 207, a lead screw mechanism 206, a rotating cap 204 and a rotating handle 205. The support base is fixedly connected with the first leveling plate 203 and is used for supporting the motor 3 under test. One end of the chain 207 is fixedly connected with one side of the support base, and the other end is fixedly connected with the sliding block of the lead screw mechanism 206. The lead screw of the lead screw mechanism 206 is in rotating fit with the support base. The rotating handle 205, the rotating cap 204 and the lead screw are sequentially fixedly connected. When the rotating handle 205 is rotated, the lead screw drives the sliding block to move, and then the motor 3 under test is pulled towards the support base through the chain 207, so that the chain 207 presses the motor 3 under test. In combination with the first pressing unit, the motor 3 under test is stably clamped from the horizontal and vertical directions.

[0044] The pushing device is fixedly connected with the base 1 and is used for pushing the measured motor 3 to slide along the length direction of the slide rail. In the embodiment, the pushing device adopts a hydraulic cylinder 405, an output end of the hydraulic cylinder 405 is connected with the measured motor 3 through a wire passing flange 406, the connection is stable and convenient to disassemble and assemble. The pushing device further comprises a servo hydraulic station 4 for providing power for the hydraulic cylinder 405. The servo hydraulic station 4 is provided with a hydraulic station motor 401, a control console 402, a hydraulic oil tank 403 and a hydraulic pipeline 404. The output thrust, the extension distance and the extension speed of the hydraulic cylinder 405 can be accurately adjusted by controlling the servo hydraulic station 4, and then the drilling speed, the drilling distance and the drilling pressure of the permanent magnet direct drive electric drilling tool are changed, so as to simulate the drilling parameters under different working conditions. The specific structure, working principle of the servo hydraulic station 4 and the realization of the driving of the hydraulic cylinder 405 by the servo hydraulic station 4 for providing hydraulic oil for the hydraulic cylinder 405 are very mature existing technologies, so the embodiment will not be described in detail.

[0045] In order to ensure the accuracy of the drilling distance, a measuring device is arranged, which is used for measuring the distance of the measured motor 3 moving along the slide rail. In the embodiment, the measuring device adopts a scale ruler 407 marked with scales. One end of the scale ruler 407 is threadedly connected with the hydraulic cylinder 405, and the scale ruler 407 is parallel to the slide rail. The scale readings of the measured motor 3 on the scale ruler 407 are read before and after the movement of the measured motor 3, and the distance of the measured motor 3 moving along the slide rail is obtained by comparison.

[0046] The second clamping mechanism 16 detachably connected with the base 1 is used for clamping the diamond block 15 to be drilled. The clamped diamond block 15 to be drilled faces the drill bit 14 and is drilled by the drill bit 14, so as to simulate the drilling process in the actual drilling. The second clamping mechanism 16 comprises a first clamping plate 1601 and a second clamping plate 1602. The first clamping plate 1601 is connected with the base 1 through bolts. The second clamping plate 1602 is connected with the first clamping plate 1601 through a plurality of mutually parallel connecting studs 1603. The distance between the first clamping plate 1601 and the second clamping plate 1602 can be changed by adjusting the connecting studs 1603, so that the diamond block 15 to be drilled with different sizes is clamped. Specifically, two fifth adjusting nuts 1605 and two sixth adjusting nuts 1604 are threadedly connected on each connecting stud 1603. The first clamping plate 1601 is clamped by the two fifth adjusting nuts 1605 on the same connecting stud 1603, and the second clamping plate 1602 is clamped by the two sixth adjusting nuts 1604 on the same connecting stud 1603. Through holes are arranged on the first clamping plate 1601 and the second clamping plate 1602, so that the drill bit 14 passes through to contact the diamond block 15 to be drilled, so as to ensure the smooth progress of the drilling process.

[0047] The torque and speed measuring module is used for testing torque and speed parameters of the motor 3 under test, and comprises a fixed magnetic powder brake 6, a torque and speed sensor 7 and a base 5. The input end of the torque and speed sensor 7 is detachably connected with the output shaft of the motor 3 under test through a shaft coupling 8, and the output end is detachably connected with the input end of the magnetic powder brake 6. The torque and speed of the motor 3 under test can be detected in real time through the torque and speed sensor 7. The base 5 comprises a fixed base plate 501 and a second leveling plate 502. The second leveling plate 502 is connected with the fixed base plate 501 through a plurality of vertical second adjusting studs 503. A third adjusting nut 504 above the second leveling plate 502 and a fourth adjusting nut 505 below the second leveling plate 502 are threadedly connected on each second adjusting stud 503. The second leveling plate 502 is sleeved on all the second adjusting studs 503. The height of the second leveling plate 502 can be adjusted through the third adjusting nut 504 and the fourth adjusting nut 505, so as to adjust the height of the magnetic powder brake 6 and the torque and speed sensor 7, and ensure the coaxiality of the magnetic powder brake 6, the torque and speed sensor 7 and the output shaft of the motor 3 under test, thereby avoiding the influence of height deviation on the test precision. Meanwhile, a pad 13 is arranged between the torque and speed sensor 7 and the base 1, and the pad 13 is used for keeping the torque and speed sensor 7 stable. In addition, the torque and speed measuring module further comprises a computer 12. The torque and speed sensor 7 is signal connected with the computer 12, and the detected torque and speed data can be transmitted to the computer 12 in real time for recording and analysis. The computer 12 can also control the current of the magnetic powder brake 6. The load of the motor 3 under test can be adjusted by changing the braking torque of the magnetic powder brake 6, so as to simulate the running state of the motor 3 under test under different load conditions.

[0048] It is worth noting that the test device of the embodiment further comprises a transformer 10, a general switch 9 and a frequency converter 11. The transformer 10 is used for raising the input voltage to the rated voltage of the motor under test. The general switch 9 is the power switch of the whole test system. The frequency converter 11 is used for controlling the speed of the motor under test.

[0049] In use, the test device of the embodiment can select a test mode according to test requirements. When it is required to simulate the actual drilling condition, the drill bit 14 is installed on the output shaft of the motor 3 under test. The diamond block 15 is fixed by the second clamping mechanism 16. The motor 3 under test is moved by the pushing device, so that the drill bit 14 drills into the diamond block 15, and the drilling performance test is realized. When it is required to test the torque and speed characteristics of the motor 3 under test under different loads, the output shaft of the motor 3 under test is connected with the input end of the torque and speed sensor 7, and the output end of the torque and speed sensor 7 is connected with the input end of the magnetic powder brake 6. The load of the magnetic powder brake 6 is adjusted by the computer 12. At the same time, the parameters are detected by the torque and speed sensor 7 and transmitted to the computer 12, and the load performance test is completed.

[0050] The test device of the embodiment does not need to rely on an ocean drilling ship for deep sea test, and the performance test of the electric drilling tool can be completed on land, so that the time and fund cost of the test are greatly reduced; meanwhile, the safety hidden danger caused by unknown motor performance in the sea test is avoided, and the test safety is improved. In addition, through the adjustment function of the first clamping mechanism 2, the parameter control of the pushing device, the load adjustment and data acquisition of the torque and speed measurement module, the test requirements of different specifications of the electric drilling tool can be adapted, and the accurate test of the drilling parameters, torque and speed and other performances can be realized, so that an efficient and reliable solution for the performance verification of the electric drilling tool is provided.
