Description

Technical Field

[0001] This utility model relates to the field of pump manufacturing and processing technology, and more specifically, to an automatic feeding and pressing device for pump components. Background Technology

[0002] A pump is a machine that transports or pressurizes fluids. It transfers the mechanical energy of a prime mover or other external energy to a liquid, increasing the liquid's energy. Pumps are mainly used to transport liquids such as water, oil, acid and alkali solutions, emulsions, suspensions, and liquid metals. They can also transport liquid-gas mixtures and liquids containing suspended solids.

[0003] Pump components typically refer to the core parts of a pump, such as the impeller, pump shaft, pump body, suction port, and discharge port. Currently, bushings are usually installed at the suction port and discharge port to facilitate assembly with other external components and improve ease of use.

[0004] For example, CN117182523A discloses a pneumatic device and working method for bushing crimping, including: a base, a crimping table fixedly mounted on the base, and a pressure head slidably mounted on the base, wherein the pressure head is adapted to press workpiece one into workpiece two. However, in this device, workpiece one and workpiece two need to be manually clamped and aligned, which is time-consuming, labor-intensive, and prone to errors during alignment. This can easily lead to damage to the bushing during crimping, resulting in low and inconsistent production efficiency of the pump assembly and increased costs. In addition, the device has an unreasonable layout, occupies a large space, and has significant limitations. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an automatic feeding and pressing device for pump components.

[0006] The objective of this utility model is achieved through the following technical solution: An automatic feeding and pressing device for a pump assembly includes a base plate and a transmission assembly disposed thereon. A transmission plate is slidably disposed on the transmission assembly. The transmission plate is provided with a positioning assembly for positioning the pump body and a bearing assembly for supporting the bushing. A robotic arm is provided on one side of the transmission assembly and a pressing assembly is provided on the other side. The pressing assembly includes at least a pressing frame fixed on the base plate. A support block is fixed on the pressing frame. A top rod is provided directly below the support block. The central axis of the top rod is coaxial with the central axis of the bearing assembly.

[0007] Preferably, the bearing assembly includes at least a bushing fixed to the transmission plate, the bushing having a fitted sliding shaft, a limiting ring sleeved on the sliding shaft, the limiting ring being located at both ends of the bushing; a lower stop fixed to the bottom end of the sliding shaft, a first spring sleeved on the sliding shaft being provided between the lower stop and the limiting ring located below; and an upper stop fixed to the top end of the sliding shaft, a second spring sleeved on the sliding shaft being provided between the upper stop and the limiting ring located above.

[0008] Preferably, the positioning component includes at least a left baffle fixedly disposed on one side of the transmission plate, a drive cylinder fixedly disposed on the other side of the transmission plate, and a right baffle fixedly disposed on the cylinder shaft of the drive cylinder.

[0009] Preferably, a front baffle is fixed at one end of the transmission plate, and a servo cylinder is fixed at the other end, with a rear baffle fixed on the cylinder shaft of the servo cylinder.

[0010] Preferably, the transmission assembly includes at least a support block fixed on the base plate, a transmission frame fixed on the support block, a transmission screw pivotally mounted inside the transmission frame, one end of the transmission screw connected to a transmission motor, a transmission nut for screw-driven transmission on the transmission screw, and a transmission plate fixed on the transmission nut.

[0011] Preferably, a position sensor is fixed on the transmission frame, and a sensing plate is fixed on the transmission plate, the sensing plate being placed in the sensing slot of the position sensor.

[0012] Preferably, the crimping assembly further includes an electric cylinder fixedly mounted on the crimping frame, and the push rod is fixedly mounted on the output end of the electric cylinder.

[0013] Preferably, a first support rod is provided on one side of the transmission plate, and a barcode scanner is provided on the first support rod for scanning the pump body. A second support rod is provided on the other side of the transmission plate, and a monitor is provided on the second support rod for monitoring the position of the bushing.

[0014] Preferably, it also includes a support rod fixed on the substrate, on which a CCD camera is fixed.

[0015] The beneficial effects of this utility model are mainly reflected in: 1. The device is ingeniously designed with a reasonable layout and exquisite structure. It achieves automatic positioning and pressing, and the entire process is automated without manual operation, which greatly improves work efficiency. Moreover, the mechanical positioning and pressing is stable and reliable, which maximizes the yield rate and has a wide range of applications.

[0016] 2. The first and second springs work together to promptly reset the bushing after crimping, facilitating the next operation and greatly improving work efficiency. Simultaneously, the sliding shaft's up-and-down movement during crimping prevents damage to the bushing, thus increasing the yield rate.

[0017] 3. The bushing can reduce friction of the sliding shaft during sliding, extend its service life, and also reduce noise generation.

[0018] 4. The transmission plate adopts a screw drive, which takes advantage of its characteristics of low friction loss, high transmission efficiency and high precision. At the same time, the position sensor and the sensing plate work together to monitor the position of the transmission plate in real time, so as to ensure the accuracy of the movement position of the transmission plate.

[0019] 5. The pump body is precisely positioned by cooperating with the drive cylinder and the servo cylinder to drive the right baffle, the left baffle, the rear baffle, and the front baffle. This structure is simple, convenient, stable, and reliable, greatly improving work efficiency.

[0020] 6. Electric cylinders are high-precision transmission devices that use electrical energy to drive linear motion. Compared with traditional hydraulic drives, they have lower noise levels and more stable operating accuracy. In addition, they also have advantages such as fast response and excellent accuracy.

[0028] The transmission plate 21 is provided with a positioning component 3 for positioning the pump body 100 and a bearing component 4 for supporting the bushing. Specifically, the bearing component 4 includes at least a bushing 41 fixed on the transmission plate 21. The bushing 41 has a fitted sliding shaft 42 inside it.

Furthermore, the CCD camera 75 includes an optical lens connected to the camera body, and the image sensor and ADC are housed inside the camera body. The optical lens focuses external light onto the image sensor, which is beneficial for the system to acquire clear images.

[0033] The working process of this utility model is briefly described below: The bushing 41 is fitted onto the sliding shaft 42, and the pump body 100 is placed on the support plate 21. At this time, the drive cylinder 32 and the servo cylinder 35 extend, and the right baffle, left baffle, rear baffle and front baffle cooperate to position the pump body 100.
