Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of ball milling and polishing equipment, specifically a polishing device for processing water pump housings. Background Technology
[0002] In traditional water pump casing manufacturing processes, surface polishing is typically performed manually or using single-axis rotary polishing equipment. Common equipment structures include a fixed cylindrical structure with an electrically driven rotating shaft, internally loaded with polishing media (such as abrasive particles). The initial polishing of the inner and outer surfaces of the casing is achieved through physical friction caused by the cylinder's rotation. However, such equipment generally suffers from several significant drawbacks:
[0003] First, most existing polishing equipment has a single rotating structure, where the grinding cylinder can only rotate around a single axis, lacking the ability to dynamically adjust the tilt angle. This makes the movement trajectory of the grinding particles within the cylinder too uniform, easily leading to some areas being polished sufficiently while others are underpolished, resulting in uneven surface treatment of the water pump housing and the presence of dead corners.
[0004] Secondly, the power transmission system in traditional equipment usually uses a single motor to drive a single shaft rotation, lacking multi-point linkage and variable angle adjustment structure, resulting in low overall transmission efficiency. During operation, belt slippage or transmission instability is prone to occur, affecting equipment reliability and polishing consistency.
[0005] In addition, the ball mill cylinder and drive shaft are mostly rigidly connected, with a simple transmission structure and a lack of matching adjustment mechanism or tension control device. Once the load is unbalanced, it is easy to cause the equipment to shake or wear abnormally, reducing the service life of the equipment.
[0006] In summary, existing water pump housing polishing equipment has significant limitations in terms of ball mill particle movement path control, equipment operation stability, and polishing uniformity. There is an urgent need for an improved polishing equipment with a more optimized structure that can achieve multi-axis linkage and angle control in order to improve polishing quality and equipment operating efficiency. Utility Model Content
[0007] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.
[0008] Therefore, the technical solution adopted by this utility model is as follows: a polishing device for processing water pump housings, including a support frame, a ball mill cylinder, and a multi-axis drive assembly. A support seat is fixedly installed on the top surface of the support frame, and bearing seats are provided at both ends of the support seat. A first drive motor and a second drive motor are respectively fixedly installed on the surface of the bearing seats. The multi-axis drive assembly includes a shaft platform, a transmission shaft, a mandrel, and a worm gear shaft. The mandrel and worm gear shaft are rotatably mounted on the surface of the shaft platform. The transmission shaft is connected to the bearing seats. Gear rings are provided at both ends of the shaft platform and are rotatably connected to the bearing seats. The motors drive each shaft to rotate through a transmission device, thereby realizing the combined motion of tilting and rotating the ball mill cylinder.
[0009] In a preferred embodiment, the second drive motor output drives the transmission shaft to rotate via a pulley. The transmission shaft engages with a gear ring to control the deflection of the bearing platform, thereby dynamically adjusting the tilt angle of the grinding cylinder. Specifically, adjusting the tilt angle changes the movement path of the grinding particles within the cylinder, thus enhancing the polishing effect on the complex surfaces of the casing.
[0010] In a preferred embodiment, the first drive motor output is further configured such that a worm gear meshes with a worm wheel shaft, and drives a mandrel to rotate synchronously via a belt. The mandrel is connected to a shaft at the bottom of the grinding cylinder via a coupling, thereby driving the grinding cylinder to rotate stably. Specifically, this composite drive structure enables synchronous coordination of tilt control and rotation functions, increases the complexity of the polishing trajectory, and improves the uniformity of polishing on the shell surface.
[0011] In a preferred embodiment, the ball mill cylinder is further configured such that a bearing groove is provided at its bottom for sliding engagement with a bearing disc on the surface of the bearing platform, enabling the ball mill cylinder to maintain stable rotation under deflection. Specifically, this structure can maintain rotational balance when the cylinder is tilted, preventing vibration or displacement and improving the reliability of equipment operation.
[0012] In a preferred embodiment, the shaft assembly is further configured with a belt, guide pulley, and tension assembly inside to adjust the tension of the belt drive between the spindle and the worm gear shaft. Specifically, the tension assembly can dynamically adjust the tightness of the transmission structure according to the actual operating load, effectively preventing belt slippage and transmission problems, and improving equipment stability and service life.
[0013] In a preferred embodiment, several agitators are fixed inside the grinding cylinder to agitate the grinding particles and facilitate multi-angle contact and friction between the grinding particles and the shell surface during the rotation of the grinding cylinder. Specifically, this structure guides the particles into a turbulent state through the agitators, enhancing the coverage of particle distribution and thus achieving polishing without dead angles on the inner and outer surfaces.
[0014] In a preferred embodiment, the ball mill cylinder is further configured such that it contains ball milling particles of a preset size and hardness, with different types of particles selectable based on the shell material and target roughness. Specifically, the combined action of the ball milling particles, the stirring plate, and the cylinder forms a dynamic grinding path, improving the consistency and control precision of the polishing effect.
[0015] In summary, this utility model, by constructing a composite drive structure with tilt adjustment and active rotation functions, and in conjunction with a stable rotation support, tension adjustment, and particle disturbance mechanism, achieves efficient, uniform, and stable polishing of the water pump housing during the processing, and has significant practical value and promotion potential.
[0016] The beneficial effects achieved by this utility model are as follows:
[0017] 1. In this utility model, the tilt angle adjustment and active rotation of the ball mill cylinder are realized through a multi-axis drive assembly, so that the ball mill particles form a complex disturbance trajectory inside the ball mill cylinder, thereby significantly improving the polishing uniformity and surface quality of the water pump housing, and effectively solving the problems of uneven polishing and dead corner residue in existing equipment.
[0018] 2. In this utility model, through the composite transmission structure design between the transmission shaft, shaft gear ring, worm gear shaft and mandrel, the ball mill cylinder can achieve a dual motion mode of tilting and rotation during operation. At the same time, the tension component adjusts the belt stability, thereby improving the reliability and transmission efficiency of the equipment operation. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.
[0029] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.
[0030] The following describes, with reference to the accompanying drawings, some embodiments of a polishing device for processing water pump housings provided by this utility model.
[0031] Combination Figures 1-5 As shown, the present invention provides a polishing device for processing water pump housings, including a support frame 100, a ball mill cylinder 200, and a multi-axis drive assembly 300. A support 110 is fixedly mounted on the top surface of the support frame 100, and bearing seats 113 are fixedly mounted on both ends of the support 110. A first drive motor 111 and a second drive motor 112 are respectively fixedly mounted on the surface of the bearing seats 113.
[0032] The multi-axis drive assembly 300 includes a shaft platform 310, a drive shaft 320, a spindle rod 330, and a worm gear shaft 340. The spindle rod 330 and the worm gear shaft 340 are rotatably mounted on the surface of the shaft platform 310. Both ends of the shaft platform 310 are provided with gear rings 312, the sides of which are rotatably connected to the surface of the bearing seat 113. The drive shaft 320 is rotatably mounted on the surface of the bearing seat 113. The output end of the second drive motor 112 is connected to the end of the drive shaft 320 via a pulley. The drive shaft 320 is connected to the surface of the gear rings 312 via a belt drive, thereby driving the shaft platform 310 to achieve deflection motion, further realizing the reciprocating control of the tilt angle of the ball mill cylinder 200.
[0033] The output end of the first drive motor 111 is connected to a worm gear, which meshes with the surface of the worm wheel shaft 340 for transmission. The worm wheel shaft 340 and the spindle shaft 330 are connected by a belt drive, thereby realizing the rotation of the spindle shaft 330, which in turn drives the ball mill cylinder 200 to rotate actively.
[0034] Specifically, the output end of the first drive motor 111 is connected to a worm gear that meshes with the surface of the worm gear shaft 340. The first drive motor 111 and the second drive motor 112 are arranged coaxially with the shaft gear ring 312. The spindle rod 330 is located on the axis of the bearing plate 311, and the spindle rod 330 is arranged coaxially with the ball mill cylinder 200.
[0035] The bottom of the ball mill cylinder 200 is provided with a bearing groove 220 for sliding contact with the bearing plate 311 on the surface of the shaft platform 310, so that the ball mill cylinder 200 can rotate stably on the shaft platform 310. A shaft 230 is fixedly installed at the bottom end of the ball mill cylinder 200, and the shaft 230 is connected to the mandrel 330 through a coupling to realize power transmission.
[0036] To ensure stable belt drive between the spindle rod 330 and the worm gear shaft 340, the shaft base 310 is equipped with a belt, several guide pulleys, and a tension assembly to adjust the belt tension and maintain the stability and accuracy of the transmission.
[0037] Several stirring plates 210 are fixedly installed inside the ball mill cylinder 200 to drive the grinding particles to perform agitation. The ball mill cylinder 200 is filled with grinding particles. Under the rotation of the ball mill cylinder 200 and the action of the stirring plates 210, the grinding particles come into contact with and rub against the surface of the water pump housing at multiple angles and directions, thereby achieving fine polishing of its inner and outer surfaces.
[0038] In actual use, the water pump housing to be processed is placed inside the ball mill cylinder 200, and the first drive motor 111 and the second drive motor 112 are started sequentially through the control system. The second drive motor 112 drives the transmission shaft 320 to rotate, and drives the shaft gear ring 312 to deflect the shaft platform 310 through belt transmission, thereby realizing the tilt angle adjustment of the ball mill cylinder 200. The first drive motor 111 drives the worm gear shaft 340 to rotate through the worm, and drives the spindle rod 330 to rotate through belt transmission, thereby driving the ball mill cylinder 200 to achieve active rotation.
[0039] The ball mill cylinder 200 slides on the bearing plate 310 via the bearing groove 220 and the bearing disk 311 to achieve stable rotation. The ball mill particles, agitated by the stirring plate 210, uniformly polish the water pump housing. After polishing, the equipment is shut down, and the finished water pump housing is removed.
[0040] Working principle and usage process of this utility model:
[0041] This invention achieves efficient rotation of the grinding cylinder 200 and uniform polishing of the water pump housing by the grinding particles inside it through the setting of a multi-axis drive assembly 300. Its main working process is as follows:
[0042] The second drive motor 112 drives the transmission shaft 320 to rotate via a pulley. The transmission shaft 320 is connected to the gear rings 312 at both ends of the shaft platform 310, thereby driving the shaft platform 310 to deflect and reciprocate to control the tilt angle of the ball mill cylinder 200.
[0043] Meanwhile, the output end of the first drive motor 111 is driven by a worm gear meshing with the surface of the worm wheel shaft 340. The worm wheel shaft 340 then drives the spindle shaft 330 to rotate via a belt, thereby realizing the active rotation of the ball mill cylinder 200. The bottom of the ball mill cylinder 200 is provided with a bearing groove 220, which slides in cooperation with the bearing plate 311 on the surface of the shaft table 310, so that the ball mill cylinder 200 can rotate stably on the shaft table 310.
[0044] Inside the ball mill cylinder 200, several stirring plates 210 are fixedly installed, and ball milling particles are added. During the operation of the equipment, under the action of the stirring plates 210, the ball milling particles are driven to perform multi-directional and uniform mechanical friction on the water pump housing, thereby achieving fine polishing of the inner and outer surfaces of the housing.
