Description

Technical Field

[0001] This utility model relates to the technical field of motor lifting force testing devices, and in particular to a motor lifting force testing device. Background Technology

[0002] After the motor is assembled and before leaving the factory, its lifting capacity needs to be tested to ensure its normal operation. Currently, most motor lifting capacity tests are conducted manually. Testers place the motor under test on a corresponding test fixture, add a load to the motor's main shaft, and start the motor. They then observe whether the motor can pull the load, thus determining whether the motor's lifting capacity meets the requirements. This testing method not only requires highly skilled personnel and techniques, increasing the risk of human error, but is also time-consuming, labor-intensive, and inefficient. Utility Model Content

[0003] In view of the shortcomings of the prior art, this utility model provides a motor lifting force testing device, which, after improvement, can effectively solve the problems mentioned in the background art.

[0004] The technical solution of this utility model is as follows:

The first belt conveyor and the second belt conveyor are respectively screwed to both ends of the top surface of the workbench. The conveying mechanism is screwed to the top surface of the workbench and located between the first belt conveyor and the second belt conveyor. The feeding mechanism is screwed to the top of the workbench. The testing mechanism is screwed to the inner top of the workbench. A notch is provided on the top surface of the workbench and directly above the testing mechanism.

[0006] The feeding mechanism includes a moving device, a lifting device, and a pushing rod. The moving device is screwed onto the top surface of the workbench. The moving end of the moving device is screwed onto the lifting device. The moving end of the lifting device is screwed onto the pushing rod. The bottom ends of the pushing rod are screwed onto a first pushing plate and a second pushing plate, respectively.

[0007] The conveying mechanism includes a first electric slide rail, a second electric slide rail, and a mounting plate. The top surface of the workbench is screwed with the first electric slide rail and the second electric slide rail respectively. The mounting plate is screwed between the first electric slide rail and the second electric slide rail. The front end of the top surface of the mounting plate is screwed with a power supply device. The rear end of the top surface of the mounting plate is screwed with the first linear slide rail and the second linear slide rail respectively.

[0008] The testing mechanism includes a lifting device, a connector, a rotating wheel, an auxiliary wheel, a weight, a pull wire, and a proximity switch. A connecting plate is screwed onto the inside of the workbench, and the lifting device is screwed onto the connecting plate. The moving end of the lifting device is screwed onto a fixed plate. A connector is screwed onto the inner side of the fixed plate, and a rotating wheel is rotatably connected to the bottom surface of the connector via a first rotating shaft and a first bearing. A side plate is screwed onto the inner side of the fixed plate, and an auxiliary wheel is rotatably connected to one end of the side plate via a second rotating shaft and a second bearing. A pull wire is wound around the rotating wheel, and the other end of the pull wire is connected to the auxiliary wheel and to a weight. A proximity switch is also screwed onto the inside of the workbench, and the proximity switch is positioned directly opposite the weight.

[0009] Furthermore, a first cylinder is screwed onto the top surface of the workbench, located at the right end of the first belt conveyor, and a limit block is screwed onto the push rod end of the first cylinder.

[0010] Furthermore, the moving device includes a first fixed column and a second fixed column. The top surface of the worktable is respectively screwed with the first fixed column and the second fixed column, and an electric slide is screwed between the first fixed column and the second fixed column.

[0011] Furthermore, the lifting device includes a connecting block and a first lifting cylinder. The slider end of the electric slide is connected to the connecting block by screwing. The first lifting cylinder is installed on the connecting block by screwing. The push rod end of the first lifting cylinder is installed with a fixing block by screwing. The other end of the fixing block is fixedly connected to the push rod by screwing.

[0012] Furthermore, the power supply device includes a power supply box, a second cylinder, a pressure block, and a pin. The power supply box, the second cylinder, and the pressure block are respectively screwed onto the front end of the top of the mounting plate. The pressure block is provided with a connection hole, and a pin is inserted into the pressure block. The push rod end of the second cylinder is fixed to the pressure block by screwing.

[0015] The beneficial effects of this utility model are as follows:

[0016] Compared with existing technologies, this utility model features a feeding mechanism that transports the motor from the first belt conveyor to the mounting plate on the conveying mechanism. The conveying mechanism then transports the motor directly above the testing mechanism. An energizing device connects the motor to the energizer. A lifting device on the testing mechanism effectively moves the fixing plate and its connecting components upwards, allowing the motor's main shaft to be inserted into the connector's socket and the first rotating shaft's slot. Once the motor is started, the rotating shaft drives the rotating wheel, causing the pull wire to lift the weight. A proximity switch effectively detects whether the weight has been lifted into position, thus determining whether the lifting force of the motor meets the requirements. This process eliminates the need for manual operation, reducing labor costs and minimizing errors caused by human testing. Furthermore, this equipment has a high degree of automation, requiring no human intervention and allowing multiple motors to be tested in a single operation, greatly improving testing efficiency and making it highly practical.

A power supply device 15 is screwed onto the front top surface of the mounting plate 14, and a first linear slide rail 16 and a second linear slide rail 17 are screwed onto the rear top surface of the mounting plate 14. The testing mechanism 6 includes a lifting device 18, a connector 19, a rotating wheel 20, an auxiliary wheel 21, a weight 22, a pull wire 23, and a proximity switch 24. A connecting plate 25 is screwed onto the interior of the workbench 1, and the lifting device 18 is screwed onto the connecting plate 25. The moving end of the lifting device 18 is screwed... A fixed plate 26 is connected, and a connector 19 is screwed onto the inner side of the fixed plate 26. A rotating wheel 20 is rotatably connected to the bottom surface of the connector 19 via a first rotating shaft and a first bearing. A side plate 27 is also screwed onto the inner side of the fixed plate 26. An auxiliary wheel 21 is rotatably connected to one end of the side plate 27 via a second rotating shaft and a second bearing. A pull wire 23 is wound around the rotating wheel 20, and the other end of the pull wire 23 is connected to the auxiliary wheel 21 and a weight 22. A proximity switch 24 is also screwed onto the inside of the workbench 1, and the proximity switch 24 is positioned directly opposite the weight 22.

[0026] In a preferred embodiment, a first cylinder 28 is screwed onto the top surface of the workbench 1, located at the right end of the first belt conveyor 2. A limit block 29 is screwed onto the push rod end of the first cylinder 28. It is understood that the first cylinder 28 is located in the middle of the two pulleys at the right end of the first belt conveyor 2, and neither the first cylinder 28 nor the limit block 29 is in contact with the first belt conveyor 2.

[0027] In a preferred embodiment, the moving device 7 includes a first fixed column 30 and a second fixed column 31. The top surface of the worktable 1 is screwed with the first fixed column 30 and the second fixed column 31, respectively. An electric slide 32 is screwed between the first fixed column 30 and the second fixed column 31. It is understood that the electric slide 32 is located above the worktable 1 and does not interfere with other structures.

[0029] In a preferred embodiment, the energizing device 15 includes a power supply box 36, a second cylinder (not shown), a pressure block 37, and a pin 38.

The pressure block 37 has a connecting hole, and the pin 38 is inserted into the pressure block 37. The push rod end of the second cylinder is fixed to the pressure block 37 by screwing. The power supply box 36 is electrically connected to the pin 38 via a wire. This structure achieves mechanical energization of the motor, ensuring safe and reliable energization and facilitating subsequent lifting force testing of the motor. Furthermore, this application can energize multiple motors in a single operation, significantly improving efficiency. Simultaneously, the motor structure is a motor-connected circuit board structure; energization is achieved after the pin 38 contacts the socket on the circuit board.

[0030] In a preferred embodiment, the lifting device 18 includes a second lifting cylinder 39 and a third lifting cylinder 40. The second lifting cylinder 39 and the third lifting cylinder 40 are respectively screwed onto both ends of the bottom surface of the connecting plate 25. The push rod ends of the second lifting cylinder 39 and the third lifting cylinder 40 are respectively screwed to a first connecting seat 41 and a second connecting seat 42. The other ends of the first connecting seat 41 and the second connecting seat 42 are respectively screwed to a fixed plate 26. By providing the second lifting cylinder 39 and the third lifting cylinder 40, during synchronous operation, the fixed plate 26 can be driven to move up and down, thereby driving its connecting structure to move up and down, quickly realizing the testing process and improving efficiency.

[0031] In a preferred embodiment, the connector 19 is provided with an insertion hole, and the top surface of the first rotating shaft is provided with a slot, the insertion hole and the slot being connected. It can be understood that during the lifting process of the fixing plate 26, the motor's main shaft will be inserted into the insertion hole on the connector 19, and upon further insertion, it will be inserted into the slot of the first rotating shaft, where the slot and the main shaft are engaged and fixed.

[0032] The working principle of this utility model is as follows: During operation, several motors (motor connected to circuit board structure) are first manually placed on the first belt conveyor 2 for conveying. The first cylinder 28 lifts the limiting block 29 to limit the motors. After the first belt conveyor 2 is filled with motors, the electric slide table 32 is started, which drives the push rod 9 to move to the left. After it reaches the position, the first lifting cylinder 34 is started, which drives the push rod 9 to move down. At this time, the first push plate 10 is locked on the motor at the leftmost end of the first belt conveyor 2. Then, the first cylinder 28 is started to move the limiting block 29 down, and the electric slide table 32 drives the push rod 9 to move to the right, which can convey several motors to the right. The motors leave the first belt conveyor 2 and move to the first linear slide rail 16 and the second linear slide rail 17 (the first belt conveyor 2, the mounting plate 14 and the second belt conveyor 3 are corresponding and close to each other, so that the motors can move from the first belt conveyor 2 to the mounting plate 14 and from the mounting plate 14 to the second belt conveyor 3). Then, the second cylinder is started, which drives the pressure... Block 37 and pin 38 move downwards, at which point pin 38 is inserted into the circuit board connected to the motor, energizing the motor. Next, the first electric slide rail 12 and the second electric slide rail 13 are activated, transporting the mounting plate 14 and its connecting components forward together. Once in position, the second lifting cylinder 39 and the third lifting cylinder 40 are activated, causing the fixing plate 26 and its connecting components to move upwards. At this point, the motor's main shaft is inserted into the socket of the connector 19 and the slot of the first rotating shaft (the motor's main shaft is locked and fixed in the slot of the first rotating shaft). After the motor is started, the rotation of the motor spindle drives the rotating wheel 20 to rotate (the rotation of the rotating wheel 20 causes the pull wire 23 to rotate, which in turn drives the auxiliary wheel 21 to rotate, allowing the pull wire 23 to move up and down in the vertical direction, thereby allowing the weight 22 to move up and down). This causes the pull wire 23 to pull up the weight 22, and the proximity switch 24 (located in the detection position, near the connecting plate 25) can effectively detect whether the weight 22 has been pulled up in place, thereby determining whether the lifting force of the motor under test meets the requirements. In addition, this equipment is a continuous pushing process. After the motor test is completed, the first electric slide rail 12 and the second electric slide rail 13 will drive the mounting plate 14 and its connecting parts back to their original positions. When the electric slide table 32 is started again, the first push plate 10 will push several motors to be tested onto the mounting plate 14, while the motors that have been tested will pass through the second push plate 11, which will push several motors that have completed the test to the second belt conveyor 3, and then the second belt conveyor 3 will transport them to the next station.

[0033] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
