The motor shaft of the motor to be assembled is inserted into the assembly hole, and the cylinder pushes the push block to move along the guide groove until the push block and the positioning block are abutted and no longer move, at which time the notch below the push block and the positioning block just match each other, and the spring clamp in the spring clamp groove is just pushed onto the motor shaft, and the spring clamp is installed on the motor shaft.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: during use of the above-mentioned device, the motor shaft needs to be inserted into the assembly hole. Due to errors in the motor assembly or unstable insertion of the rotating shaft, the height of the annular groove on the motor shaft may be inconsistent with the height of the retaining spring groove on the push block, making it impossible for the retaining spring to be inserted into the annular groove, thereby reducing the success rate of the retaining spring installation and affecting the efficiency of the retaining spring installation.

[0033] The detection assembly 30 includes a vertical rod 31, on which an upper detection plate 32 and a lower detection plate 33 are vertically spaced. The upper detection plate 32 is used to detect the height of the motor rotor shaft, and the lower detection plate 33 is used to detect the height of the motor housing. When the height of the motor rotor shaft is higher than the set value, it will be blocked by the upper detection plate 32, and when the height of the motor housing is higher than the set value, it will be blocked by the lower detection plate 33, resulting in the inability to slide onto the placement seat 11. The process of first detecting and then punching the clip spring is adopted to detect unqualified motors in advance, thereby improving the efficiency of the clip spring installation. A circular hole 34 is provided on the plate surface of the upper detection plate 32 and the lower detection plate 33 near one end of the vertical rod 31. The upper detection plate 32 and the lower detection plate 33 are both slidably mounted on the vertical rod 31 through the circular hole 34, so that the height of the upper detection plate 32 and the lower detection plate 33 can be adjusted according to the size of different motors.

In specific settings, two groups of detection components 30 can be provided to enhance the detection effect, and only the upper detection plate 32 or the lower detection plate 33 can be installed according to specific circumstances to avoid interference, which is more flexible.

[0034] A vertical slide rail 44 is vertically arranged on the fixed frame 40, and the mounting frame 41 is slidably arranged on the vertical slide rail 44 through a slider, so that the mounting frame 41 can slide up and down along the vertical slide rail 44, driving the clamp spring assembly 50 to move up and down, so that the height of the clamp spring assembly 50 can be adjusted according to the different positions of the annular grooves of the motor rotor shafts of different models. A driving assembly 70 is arranged on the top of the fixed frame 40, which is used to drive the mounting frame 41 to move up and down. The driving assembly 70 includes a screw rod 71 vertically rotatably arranged on the top of the mounting frame 41, and a fixing block 72 is arranged on the top of the fixed frame 40. The fixing block 72 is spirally matched with the screw rod 71 through a threaded hole, and a rotating disk 73 is arranged on the top of the screw rod 71. The screw rod 71 is driven to rotate by rotating the rotating disk 73. Since the fixing block 72 is spirally matched with the screw rod 71 through the threaded hole, and the fixing block 72 is in a fixed state, the screw rod 71 moves upward, driving the mounting frame 41 to move upward. A clamping block 74 is also provided on the fixing block 72 and is sleeved on the screw rod 71. A notch 75 is vertically opened on one side of the clamping block 74. A threaded hole and a through hole are provided on the side of the notch 75 of the clamping block 74. The locking bolt is passed through the through hole and then screwed into the threaded hole, so that the clamping block 74 applies a clamping force to the screw rod 71, fixes the screw rod 71, and thereby fixes the height of the mounting frame 41.

[0035] The clamp spring assembly 50 includes a cylinder 51 horizontally arranged on the mounting frame 41, and a push plate 52 is arranged at the end of the piston rod of the cylinder 51 facing the placement seat 11, and the push plate 52 is driven to move by the cylinder 51. A U-shaped groove 53 is opened at one end of the push plate 52 near the placement seat 11, and the U-shaped opening of the U-shaped groove 53 faces the motor rotor shaft. A U-shaped plate 54 is arranged in the U-shaped groove 53, and the lower plate surface of the U-shaped plate 54 and the lower plate surface of the push plate 52 are coplanar, and the distance between the upper plate surface of the U-shaped plate 54 and the upper plate surface of the push plate 52 is consistent with the thickness of the clamp spring, and the distance between the opposite plate edges in the U-shaped plate 54 is greater than the diameter of the motor rotor shaft and less than the width of the clamp spring, so that the clamp spring can be placed on the U-shaped plate 54.

[0036] During the setting, a connecting block 42 is provided on one side of the mounting frame 41 near the placement seat 11, and a U-shaped block 43 is provided on the end of the connecting block 42 away from the mounting frame 41. The opening direction of the U-shaped block 43 is consistent with the length direction of the slide 20, and the opening of the U-shaped block 43 is located just above the center of the placement seat 11, so as to limit the motor rotor shaft. A feeding assembly 60 is provided on the connecting block 42, and the feeding assembly 60 includes a pressing block 62 and a vertically arranged I-shaped plate 61, and a plurality of retaining rings are sleeved on the I-shaped plate 61 for storage. The width of the flange plate of the I-shaped plate 61 near the cylinder 51 is smaller than the width of the other flange plate, so that the retaining ring will not fall out after being sleeved on the I-shaped plate 61, and it is also easy to fall. The flange plate of the I-shaped plate 61 away from the cylinder 51 is fixedly connected to the connecting block 42, and will not interfere with the retaining ring falling from the I-shaped plate 61. A through hole 63 that is consistent with the outer contour of the I-shaped plate 61 is provided in the pressing block 62. The pressing block 62 is slidably mounted on the I-shaped plate 61 through the through hole 63. When the push plate pushes the retaining ring at the bottom of the I-shaped plate 61 outwards and installs it on the motor rotor shaft, and then moves inwards until it is reset, the U-shaped plate 54 is located directly below the I-shaped plate 61. The pressing block 62 provides downward pressure, so that the retaining ring mounted on the I-shaped plate 61 moves downward stably, so that the lowermost retaining ring falls onto the U-shaped plate 54. The lower end of the I-shaped plate 61 is coplanar with the top surface of the push plate 52, so that when the push plate 52 moves below the I-shaped plate 61, only a retaining ring at the lower end of the I-shaped plate 61 is pushed out.

[0037] The use principle of a motor rotor clamping spring device with a detection function in the present embodiment is as follows: the motor is placed on the transverse slide rail 21 and pushed onto the placement seat 11, the upper detection plate 32 detects the height of the motor rotor shaft, and the lower detection plate 33 detects the height of the motor housing. When the height of the motor rotor shaft is higher than the set value, it will be blocked by the upper detection plate 32, and when the height of the motor housing is higher than the set value, it will be blocked by the lower detection plate 33, resulting in failure to slide onto the placement seat 11. The process of first detecting and then punching the clamping spring is adopted to detect unqualified motors in advance, thereby improving the efficiency of the installation of the clamping spring; the qualified motor will slide onto the placement seat 11, and the cylinder 51 is started to push the push plate 52 to move in the direction of the motor, and the clamping spring on the U-shaped plate 54 is installed in the annular groove on the motor rotor shaft to complete the installation of the clamping spring. Subsequently, the cylinder 51 drives the push plate 52 to reset, and the pressure block 62 provides downward pressure, so that the clamping spring at the bottom of the I-shaped plate 61 falls onto the U-shaped plate 54, waiting for the next press-fit.

[0038] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention.
