[0036] The following combination Figures 1 to 4 The embodiments of the present utility model are described.

[0037] The present embodiment relates to a pump body steel ball pressing device, which can conveniently and quickly press steel balls into preset steel ball holes on the pump body.

[0038] The pump body steel ball pressing device of this embodiment includes:

[0039] Rack 1;

[0040] A positioning seat 2, wherein the positioning seat 2 is provided with a positioning column for positioning the pump body;

[0041] A ball loading mechanism includes a hopper 31, a conveying tongue 32, and a ball loading driver 33. The ball loading driver 33 and the hopper 31 are both located on the frame 1. A discharge hole is provided below the hopper 31. The conveying tongue 32 is located between the hopper 31 and the positioning seat 2. A bracket 321 for placing steel balls is provided on the conveying tongue 32. The driver drives the conveying tongue 32 to move horizontally between the hopper 31 and the positioning seat 2. The bracket 321 is open below.

[0042] The pressing mechanism 4 includes a pressing driver 41 and a pressing needle 42 . The pressing driver 41 is provided on the frame 1 . The pressing driver 41 drives the pressing needle 42 to extend from above the bracket 321 toward the positioning column.

[0043] The pump body steel ball pressing device is configured with a ball loading mechanism and a pressing mechanism 4. The pump body is positioned on the positioning seat 2. The ball loading mechanism can automatically feed the material to the hole of the pump body without manual placement, reducing the difficulty of loading and improving the loading efficiency.

[0044] Specifically, the pump body is sleeved on the positioning column, and steel balls are pre-stored in the hopper 31. The steel balls fall downward from the discharge hole of the hopper 31 to the bracket 321. The ball loading driver 33 drives the conveying tongue 32 to move, so that the bracket 321 moves the steel balls to the top of the steel ball hole of the pump body, and then the pressing driver 41 drives the pressing needle 42 to press the steel balls down to the steel ball hole of the pump body, thereby completing the assembly. The loading process does not require manual participation, which reduces the labor intensity of workers and improves the efficiency of the process.

[0045] In this embodiment, to prevent steel balls from falling out of the discharge hole of hopper 31, the top surface of the conveying tongue 32 is flush with the bottom surface of the discharge hole. This leveling allows the top surface of the conveying tongue 32 to seal the discharge hole after the bracket 321 of the conveying tongue 32 leaves the discharge hole, preventing the steel balls from falling out. Thus, the movement of the conveying tongue 32 enables coordinated feeding of the discharge hole of hopper 31 and the bracket 321, eliminating the need for a separate discharge switch at the discharge hole, resulting in a streamlined and ingenious structure.

[0046] In this embodiment, the inner diameter of the feed hole decreases from top to bottom, so that when the steel ball falls into the feed hole, the top of the steel ball can be lower than the feed hole, but it will not fall out from the bottom of the feed hole. The inner diameter of the lower end of the feed hole is designed to be slightly smaller than the outer diameter of the steel ball, so that the feed hole can catch the steel ball and prevent it from falling out under the action of its own weight. At the same time, when pushed by the pressing needle 42, the steel ball can be pushed out of the feed hole by the pressing needle 42, ensuring that the steel ball can be pressed into the steel ball hole normally.

[0047] In this embodiment, to alleviate the problem of steel balls being blocked in the discharge hole and preventing discharge, the ball loading mechanism further includes an agitator 34 and an agitator shaft 35. The agitator 34 is mounted on the frame 1 and drives the agitator shaft 35 to move within the hopper 31. When the steel balls are stuck together and cannot fall from the discharge hole, the agitator 34 drives the agitator shaft 35 to rotate, thereby disturbing the steel balls and helping them fall from the discharge hole, thereby improving the operational stability of the pump body steel ball pressing device.

[0048] Specifically, the agitator 34 is a linear actuator, and the outer wall of the agitator shaft 35 is provided with a spiral structure. By providing the spiral structure on the outer wall of the agitator shaft 35, the agitator 34 uses the linear actuator to drive the agitator shaft 35 in a linear motion. The spiral structure achieves both longitudinal and lateral disturbances on the steel balls, achieving a good agitation effect. In this embodiment, the spiral structure is a spring. Using a spring has the advantages of readily available materials and low cost.

[0049] The pressing mechanism 4 also includes a steel ball sensor 43, which is signal-connected to the pressing driver 41. The steel ball sensor 43 is used to determine whether the steel ball has been positioned and placed in the steel ball hole of the pump body. When the steel ball sensor 43 detects that the steel ball has been successfully positioned and placed in the steel ball hole, it sends a signal to the pressing driver 41, which drives the pressing pin 42 to move downward, pressing the steel ball into the steel ball hole. This ensures stable pressing of the steel ball into the steel ball hole. The steel ball sensor 43 can be a photoelectric sensor, which is positioned toward the steel ball hole and feedbacks different signals depending on the distance between the photoelectric sensor and the steel ball hole. When the steel ball is placed in the steel ball hole, the distance signal received by the photoelectric sensor changes, and the distance between the photoelectric sensor and the steel ball hole decreases. The photoelectric sensor then feeds back a signal to the controller, which then issues a command to the pressing driver 41 to drive the pressing pin 42 to press the steel ball into the steel ball hole. The controller can be a conventional single-chip microcomputer or a PLC. The PLC model can be Mitsubishi FX series FX3U-128MR-ES-A, and the MCU model can be STMicroelectronics STM32F103, STM32F407, Philips LPC2220, Samsung S3C2440, etc.

[0050] The pump body steel ball pressing device also includes a clamping mechanism, which includes a clamping driver 51 and a clamping block 52. The clamping driver 51 is installed on the frame 1 and drives the clamping block 52 to move toward the positioning seat 2 to clamp the pump body. By configuring the clamping mechanism, after the pump body is placed on the positioning post, the clamping driver 51 drives the clamping block 52 to press the pump body, so that the pump body remains fixed on the positioning post. This can limit the movement of the pump body during steel ball pressing, thereby improving the accuracy of steel ball pressing.

[0051] To prevent damage to the pump body due to excessive pressure from the clamping mechanism, the clamping mechanism further includes a clamping seat 53, a clamping spring 54, a pressure rod 55, and a limiting plate 56. The clamping driver 51 is drivably connected to the clamping seat 53. The clamping seat 53 is provided with a sliding hole, along which the pressure rod 55 slides. The clamping block 52 is located on the side of the pressure rod 55 facing the positioning seat 2. The limiting plate 56 and the clamping block 52 are respectively connected to both sides of the pressure rod 55. The clamping spring 54 is located between the clamping block 52 and the clamping seat 53. When the clamping driver 51 is actuated, it drives the clamping seat 53 to move toward the pump body. The spring supports the clamping block 52 against the clamping seat 53. When the clamping block 52 presses the pump body, the spring acts as a flexible element to push the clamping block 52 against the pump body, thereby preventing the clamping block 52 from exerting excessive pressure on the pump body and damaging the pump body. Alternatively, a transversely positioned traverse cylinder can be configured to drive the clamping mechanism to move, so that when the clamping mechanism is actuated, the pressing assembly can also be driven to move laterally away from above the positioning post to facilitate placement of the pump body. Alternatively, the clamping actuator can be configured as a rotary clamping cylinder, so that the clamping block 52 rotates out of the space where the pump body is located when it is not clamping the pump body.

[0052] The pump body steel ball pressing device also includes a lateral positioning driver 61 and a lateral positioning rod 62. The lateral positioning driver 61 is installed on the frame 1 and drives the lateral positioning rod 62 to move toward the positioning seat 2. By configuring the lateral positioning driver 61 and the lateral positioning rod 62, when the pump body is placed in the positioning column, the lateral positioning driver 61 drives the lateral positioning rod 62 to move to the corresponding position on the pump body, which can apply a positioning force to the pump body from the side, further strengthening the fixing effect of the pump body and further improving the accuracy of the steel ball pressing.

[0053] The working process of the pump body steel ball pressing device is as follows: the clamping driver 51 and the lateral positioning driver 61 of the clamping mechanism first operate to clamp and position the pump body in the positioning column. After clamping in place, the operator starts the ball loading mechanism to drive the conveying tongue 32 to move, and the pressing needle 42 presses against the bracket 321, pressing the steel ball on the bracket 321 into the steel ball hole of the pump body, thereby completing the process of pressing the steel column into the pump body.

Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of the present invention.
