Description

Technical Field

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

[0002] After motor assembly and before shipment, its lifting capacity needs to be tested to ensure normal operation. Currently, motor lifting capacity testing is mostly done manually. Testers place the motor under test on the corresponding test fixture, add a load counterweight to the motor's main shaft, and start the motor, observing whether it can pull the counterweight to determine if the motor's lifting capacity meets the requirements. This testing method requires workers to install and remove motors one by one from the test fixture, consuming significant labor and incurring high labor costs. Furthermore, its low level of automation leads to reduced production efficiency. Therefore, we propose a conveying device for motor lifting capacity testing. Utility Model Content

The moving end of the lifting device 18 is screwed onto a fixing plate 26. 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.

The proximity switch 24 is positioned directly opposite the weight 22.

[0029] 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.

[0030] 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.

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.

[0033] 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.

[0034] 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.

[0035] 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.
