[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1-6 This utility model provides a technical solution: A power tool durability testing device includes a base 1, an extension plate 102 fixed at the center of one end of the base 1, a display terminal 2 fixedly installed on the top of the extension plate 102, an L-shaped enclosure seat 101 fixedly installed on the top of the base 1, and three sets of load test seats 3 evenly distributed on the back end inside the L-shaped enclosure seat 101. The load test seats 3 are electrically connected to the display terminal 2 through built-in wires. The base 1 and the L-shaped enclosure 101 together form a robust test platform for supporting and isolating the test process.

[0019] The load test stand 3 is a core functional component. Its working principle is to serve as a mounting base for the load source (magnetic powder brake) and to apply simulated working resistance to the tool under test.

[0020] Display terminal 2 serves as the human-machine interface, and its function is to receive, process, and visualize data (such as torque, speed, current, etc.) collected by the built-in sensors of load test stand 3, so as to realize real-time monitoring and data recording of the test process.

[0021] The L-shaped enclosure base 101 has three sets of base plates 4 evenly distributed on its inner bottom. The base plates 4 have a mounting seat 5 on their top. The mounting seat 5 is a special clamp for supporting and positioning the electric drill 7. The mounting seat 5 has slots on both sides of the top center. One end of the slot is equipped with a retaining ring 8 for locking and fixing the electric drill 7. The retaining ring 8 is U-shaped, and the bottom two ends of the retaining ring 8 are fixedly installed with fixing blocks 801. The fixing blocks 801 are engaged in the corresponding fixing grooves 802 opened on the inner surface of the slots. The fixing grooves 802 and the fixing blocks 801 are compatible. The U-shaped retaining ring 8 works by acting as a movable "clamp" that clamps onto the body of the electric drill 7 from top to bottom. Its bottom fixing block 801 and the fixing groove 802 on the mounting base 5 are mechanically interlocked by a snap-fit ​​mechanism. This design allows the operator to quickly and manually tighten or loosen the retaining ring 8 without tools, thus efficiently securing or removing the electric drill 7.

[0022] This utility model effectively improves the stability and reliability of clamping and fixing the electric drill 7 by setting up a mounting base 5, a retaining ring 8, a fixing block 801, a fixing groove 802, a positioning plate 9, an insert plate 901, and a slot 902, etc., and completely eliminates the safety risks and data distortion problems caused by tool loosening, shaking, or even splashing out during the testing process.

[0023] Movable blocks 401 are fixedly installed at both ends of the bottom of the substrate 4. A locking post 402 is fixedly installed on one side of one end of the movable block 401. The movable block 401 is slidably connected to the corresponding movable groove 404 opened at the bottom of the L-shaped enclosure seat 101. A column groove 403 is opened at one end of the inside of the movable groove 404. The locking post 402 is locked inside the column groove 403. A limiting plate 10 for blocking the substrate 4 from contact is provided at the outer end of the inside of the movable groove 404.

[0024] The substrate 4, the moving block 401, and the moving groove 404 configured above together constitute a sliding guide rail system, allowing the entire mounting base 5 assembly to move along a predetermined path.

[0025] Its working principle is as follows: The operator pushes the substrate 4 into the moving groove 404 through the moving block 401 until the locking post 402 slides in and locks into the post groove 403. At this time, the limiting plate 10 is taken out and inserted into the limiting groove 1001 set at the outer end of the moving groove 404 to resist and block the substrate 4. This process achieves coarse positioning and mechanical locking in one dimension, ensuring that each test station can be accurately and repeatedly positioned to the same working position, which is convenient for docking with the load test seat 3, and realizes the modular and quick replacement of the entire fixture.

[0026] This utility model, through the coordinated operation of components such as the base plate 4, the moving block 401, the locking post 402, the post groove 403, the moving groove 404, the limiting plate 10, and the limiting groove 1001, enables the mounting seat 5 to be quickly disassembled, replaced, and maintained, significantly improving testing efficiency while enhancing the practicality and maintainability of the equipment.

[0027] A drill 7 is mounted at the top center of the mounting base 5. A retaining ring 8 is provided at one top end of the drill 7, and a handle is also mounted at the top end of the drill 7. A button 701 for controlling the operation of the drill 7 is installed at the center of the handle. A positioning plate 9 for positioning and blocking is provided at the tail end of the drill 7. Insert plates 901 are fixedly mounted on both sides of the positioning plate 9. The insert plates 901 are snapped into corresponding slots 902 opened on both sides inside the mounting base 5, and the insert plates 901 and slots 902 are compatible.

[0028] This testing device is typically compatible with commercially available models (electric drill 7) with a rated voltage of 220V AC or 18V / 20V DC. Its no-load speed range is usually between 0-3000 rpm, and its maximum output torque is between 10-60 N·m. It is equipped with a standard specification (such as 10mm or 13mm) drill chuck to ensure reliable connection with the output end of the load test holder 3 and to transmit torque.

[0029] After the electric drill 7 is powered on, the button 701 of the electric drill 7 is secured with a cable tie to keep it in working state, thereby achieving the stability of the electric drill 7 test.

[0030] The positioning plate 9 acts as an axial stop, limiting the position of the drill 7 from its tail end to prevent it from shifting backward due to vibration or load during testing. The snap-fit ​​engagement between the insert plate 901 and the slot 902 enhances the stability of the positioning plate 9's hold. This structure ensures that the positioning plate 9 can be quickly and accurately installed to the predetermined depth, thereby guaranteeing axial positioning consistency for different drills 7 and further enhancing the overall rigidity and reliability of the clamping system.

[0031] The outer end of the movable groove 404 is provided with a limiting groove 1001 corresponding to the limiting plate 10, and the bottom of the limiting plate 10 is engaged inside the limiting groove 1001. One end of the movable groove 404 is equipped with a socket for inserting the power cord of the electric drill 7, and there are three sets of sockets.

[0032] A perforated plate 6 is installed at one end of the interior of the mounting base 5. The interior of the perforated plate 6 passes through the output end of the load test base 3. The output end of the load test base 3 is fixed to the output end of the electric drill 7.

[0033] The perforated plate 6 provides a guiding and protective channel to ensure that the output ends of the load test fixture 3 (such as the torque sensor and load input shaft) are precisely aligned and connected to the output ends of the drill 7 (such as the drill chuck), thereby reliably transmitting torque and speed. The socket provides a continuous power supply to the drill 7, and its multi-unit design allows for simultaneous testing at multiple stations. This centralized power supply simplifies wiring layout, avoids tangled external power cords, and improves safety and neatness.

[0034] A support column 13 is fixed to the outer end of the top front of the L-shaped enclosure base 101, and a cover 11 is installed on the top of the L-shaped enclosure base 101. Connecting columns 12 are fixedly installed around the bottom of the cover 11. The connecting columns 12 are snapped into the corresponding connecting grooves opened on the top of the L-shaped enclosure base 101 and the support column 13, and the connecting grooves and the connecting columns 12 are compatible.

[0035] The cover 11 acts as a protective shield, completely enclosing the test area during testing to prevent injury to operators from high-speed flying debris, broken tool parts, or noise. The snap-fit ​​engagement between the connecting post 12 and the connecting groove allows the cover 11 to be easily opened for tool installation and removal, and to be securely closed for safety, making it a key structure for achieving inherent safety of the equipment.

[0036] In actual use, the operator first places the electric drill 7 on the mounting base 5, and locks the electric drill 7 body from above by engaging the U-shaped retaining ring 8 with the fixing block 801 and the fixing groove 802. At the same time, the positioning plate 9 at the tail end and its insert plate 901 and slot 902 structure are used for axial positioning to achieve quick and stable clamping of the electric drill 7. Then, the entire base plate 4 assembly is pushed in along the moving groove 404 by the moving block 401, so that the retaining post 402 is engaged with the post groove 403 to complete the work position positioning, and the limiting plate 10 is inserted for final locking. After the test is started, the load test stand 3 applies a simulated working load (such as torque) to its output end. This load is guided through the perforated plate 6 and transmitted to the output end of the electric drill 7, driving the electric drill 7 to operate under the load. The current, torque, speed and other data during operation are collected by the built-in sensors of the load test stand 3 and transmitted to the display terminal 2 in real time for monitoring and recording. The entire test process is carried out under the closed cover 11. Finally, through automated operation and data acquisition, the durability and reliability of the electric drill 7 are tested efficiently and safely.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
