Description

Technical Field

[0001] This utility model relates to the field of polishing equipment technology, specifically a non-planar polishing device for axle casting parts. Background Technology

[0002] A vehicle axle (also known as a chassis axle) is connected to the vehicle frame (or monocoque chassis) via the suspension, and wheels are mounted at both ends of it. The function of the axle is to bear the load of the vehicle and maintain its normal driving on the road; axles are manufactured in various ways, with casting being the most common method.

[0003] Chinese invention patent CN118990302B, published on December 20, 2024, discloses a polishing machine tool for polishing the surface of castings. A conveyor is fixedly connected inside the fixed table, a polishing pushing mechanism is disposed at the top center of the fixed table, a clamping mechanism is disposed on the top of the conveyor, and a limit mechanism is fixedly connected to the left side of the front of the conveyor. The polishing pushing mechanism includes a polishing component and a pushing component, with the polishing component disposed on the top of the fixed table. Opening the hydraulic cylinder causes the polishing machine to move downwards, bringing the bottom of the polishing machine into contact with the top of the casting. This allows the polishing machine to polish the surface of the casting. When the polishing machine needs to be moved, the first motor is activated, causing the first motor to drive the third threaded block to move via the first threaded rod. The third threaded block then drives the hollow cylinder to move, allowing the hollow cylinder to move the polishing machine back and forth via the hydraulic cylinder, enabling the polishing machine to polish the top of the casting from both sides.

[0004] However, the above-mentioned disclosed solutions have the following shortcomings: the existing polishing devices can only polish the flat parts of the castings and cannot polish the grooved surfaces in the castings. Furthermore, because the castings are large in size, they cannot be adapted to vibratory grinding machines for grinding, resulting in a limited number of grinding methods and making it difficult to grind and polish the grooved surfaces. Utility Model Content

[0005] The purpose of this invention is to solve the technical problems of existing polishing devices, which can only polish the flat parts of castings and cannot polish the grooved surfaces of castings. Furthermore, due to the large size of castings, they cannot be adapted to vibratory grinding machines for grinding, resulting in limited grinding methods and difficulty in grinding and polishing grooved surfaces. This invention provides a non-planar grinding device for axle casting parts.

[0006] To achieve the above objectives, the present invention adopts the following technical solution;

[0007] This utility model discloses a non-planar grinding device for axle casting parts, comprising a polishing container for accommodating the axle casting parts; threaded shafts are symmetrically threaded and connected to the polishing container; a fastener is threaded and connected to one end of the threaded shaft; an extrusion plate is sleeved on the fastener; multiple vibration motors are fixedly connected to the lower surface of the polishing container; multiple inclined support rods are rotatably connected to the lower surface of the polishing container; a fixed base plate is rotatably connected to the lower end of the inclined support rods; and an elastic unit is provided on the fixed base plate corresponding to the lower surface of the polishing container.

[0008] Furthermore, the elastic unit includes a centralized base sleeved on a fixed base plate; a plurality of elastic elements are fixedly connected to the upper surface of the centralized base.

[0009] The non-planar grinding device for axle casting parts provided by this utility model has the following beneficial effects:

[0010] 1. This utility model involves placing axle casting parts requiring concave surface polishing into a polishing container, then using a hex wrench inserted into the end of a threaded shaft and rotating it to push two symmetrical extrusion plates to press and fix the axle casting parts. Nuts can then be threaded onto the threaded shaft for further fixation to prevent loosening during vibration and resulting in unstable clamping. Abrasive is then poured between the two extrusion plates to fill the remaining space until it covers the upper surface of the axle casting parts and extends beyond a certain range. Multiple vibration motors are then activated, driving the abrasive to contact the axle casting parts for polishing, enabling rapid batch polishing.

[0011] 2. This utility model uses multiple elastic elements to hold the centralized base in place, thus keeping the centralized base suspended. Under the vibration of the vibrating motor, the vibration is not transmitted to the fixed base plate and causes displacement, thus maintaining stability during use. It can also be reinforced with expansion screws. Attached Figure Description

[0017] It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0018] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] It should be noted that all directional indications (such as up-down-left-right-forward-backward...) in the embodiments of this utility model are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly. The connection can be a direct connection or an indirect connection.

[0020] Please see Figure 1-3 As shown, a non-planar grinding device for axle casting parts includes a polishing container 1 for accommodating the axle casting parts; threaded shafts 2 are symmetrically threaded onto the polishing container 1; fasteners 3 are threaded onto one end of the threaded shafts 2; extrusion plates 4 are sleeved on the fasteners 3; multiple vibration motors 6 are fixedly connected to the lower surface of the polishing container 1; multiple inclined support rods 7 are rotatably connected to the lower surface of the polishing container 1; a fixed base plate 9 is rotatably connected to the lower end of the inclined support rods 7; the fixed base plate 9 is provided with elastic units corresponding to the lower surface of the polishing container 1, allowing the polishing device to be placed inside the polishing container 1 to polish the concave surface. The axle casting parts are then processed by inserting a hex wrench into the end of the threaded shaft 2 and rotating it. This causes two symmetrical extrusion plates 4 to press and fix the axle casting parts. Nuts can then be threaded onto the threaded shaft 2 for further fixation to prevent loosening during vibration and instability in the clamping. Abrasive is then poured between the two extrusion plates 4 to fill the remaining space until it covers the upper surface of the axle casting parts and extends a certain distance above it. Then, multiple vibration motors 6 are activated, which drive the abrasive to contact the axle casting parts for grinding and polishing, enabling rapid batch polishing.

[0021] The elastic unit includes a central base 10 sleeved on the fixed base plate 9; multiple elastic elements 11 are fixedly connected to the upper surface of the central base 10. The central base 10 is held in place by the multiple elastic elements 11, thus keeping the central base 10 suspended. Under the vibration of the vibration motor 6, the vibration will not be transmitted to the fixed base plate 9 to cause displacement, thus maintaining stability during use. It can also be reinforced with expansion screws.

[0022] The extrusion plate 4 is slidably connected to the inner cavity surface of the polishing container 1, so the two extrusion plates 4 can be moved to separate the inner cavity of the polishing container 1, which can be adapted to the concave surface polishing and grinding of axle casting parts of different shapes and sizes.

[0023] A handle 5 is inserted into the other end of the threaded shaft 2. By holding the handle 5, the threaded shaft 2 is rotated, which greatly improves the rotation efficiency of the threaded shaft 2. This allows the position of the extrusion plate 4 connected to the end of the threaded shaft 2 to be quickly adjusted as needed.

[0024] The extrusion plate 4 is made of stainless steel, which makes it highly rigid and extends its service life in contact with abrasives, thereby reducing the replacement cycle of the extrusion plate 4.

[0025] A positioning shaft 8 is inserted into the lower surface of the polishing container 1 and the rotating connection of the inclined support rod 7; the same positioning shaft 8 is inserted into the rotating connection of the inclined support rod 7 and the fixed base plate 9. The positioning shaft 8 serves as the central axis of rotation, making the rotation more stable and safe, and can withstand the weight of the axle casting and the weight of the abrasive particles.
