Abstract
Description
Technical Field
[0001] This utility model relates to the field of belt grinding technology for die castings, and specifically to a belt grinding device for die castings. Background Technology
[0002] Die-cast parts are workpieces formed by the die-casting process. They are often mass-produced standard parts and all require grinding or polishing. This requires specialized grinding equipment. Different grinding fineness levels need to be met, requiring the installation of grinding belts or grinding wheels with different coarseness to achieve different degrees of grinding. Moreover, the grinding process generates a large amount of dust, which seriously pollutes the air and is not conducive to workers' work and observation of the entire grinding process. A large amount of dust will also contaminate the inner wall of the grinding equipment.
[0003] The grinding dust in existing belt grinding equipment for die castings cannot be treated in a timely manner, causing serious air pollution. For example, CN218947188U discloses a burr removal equipment for zinc alloy die castings, which includes a grinding assembly. The grinding assembly includes a worktable, a slide, a slider, a movable plate, a slide rail, a slide seat, a mounting frame, a lifting electric cylinder, a connecting plate, a grinding motor, a grinding wheel, a drive motor, gears, a toothed plate, and a displacement electric cylinder. This invention utilizes a grinding motor to rotate one end of its output shaft, which drives a grinding wheel. The piston rod of a lifting electric cylinder extends, causing the grinding wheel to move downwards to remove burrs from zinc alloy die-cast parts. The rotation of the motor's output shaft also drives a gear, which in turn moves a gear plate and a movable plate back and forth, thus moving the grinding wheel back and forth. Furthermore, the extension and retraction of the piston rod of a displacement electric cylinder moves a sliding block left and right, thus moving the grinding wheel left and right, changing the grinding position. This constitutes an automated grinding and burr removal device for zinc alloy die-cast parts. However, the dust generated during the grinding process cannot be regularly cleaned, easily causing severe air pollution within the grinding equipment and affecting the health of the operators.
[0004] Therefore, it is necessary to invent a belt grinding device for die-cast parts to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide a belt grinding device for die castings to solve the problem that a large amount of grinding dust in the air of the grinding workshop and grinding equipment cannot be absorbed and cleaned, resulting in turbid air in the grinding equipment and workshop, which affects health.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A belt grinding device for die-cast parts includes a grinding device body, a robotic arm, a material plate, a drive mechanism, and a grinding wheel. The robotic arm is installed inside the grinding device body. The grippers on the robotic arm pick up the material on the material plate and transport it to the grinding belt for grinding. The grinding belt is mounted on a drive wheel and multiple driven wheels. A grinding wheel is also arranged parallel to the grinding belt. The drive wheel is driven by the drive mechanism. Dust baffles are detachably installed on both sides of the drive mechanism. A cleaning section is provided at the bottom of the grinding device body. The length of the cleaning section is adapted to the distance between the two dust baffles.
[0008] The technical effects and advantages provided by this utility model in the above technical solution are as follows:
[0009] This invention utilizes a robotic arm, grinding belt, and grinding wheels installed within a grinding equipment to perform batch grinding of standard parts. The entire grinding process is standardized and intelligent, requiring no manual intervention and achieving high batch grinding efficiency. A detachable dust baffle is installed within the corresponding grinding position of the grinding belt to shield against grinding dust, preventing contamination of the equipment's inner wall and maintaining its cleanliness. The dust baffle guides dust towards the cleaning section, where a continuously moving suction head draws the dust into a suction mechanism where it is adsorbed and filtered by activated carbon, ensuring clean air within the grinding equipment and preventing any impact on the air quality of the entire grinding equipment or workshop, thus creating an environmentally friendly and clean operating environment.

[0016] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0017] This utility model provides, for example Figures 1-5 The invention relates to a belt grinding device for die castings, comprising a grinding device body 1, a robotic arm 2, a material plate 3, a drive mechanism 4, and a grinding wheel 8. The robotic arm 2 is installed inside the grinding device body 1. The grippers on the robotic arm 2 pick up the material on the material plate 3 and transport it to the grinding belt 6 for grinding. The grinding belt 6 is mounted on a drive wheel 5 and multiple driven wheels. The grinding wheel 8 is also arranged parallel to the grinding belt 6. The drive wheel 5 is driven by the drive mechanism 4. Dust baffles 7 are detachably installed on both sides of the drive mechanism 4. A cleaning section 9 is provided at the bottom inside the grinding device body 1. The length of the cleaning section 9 is adapted to the distance between the two dust baffles 7.
[0018] The entire grinding equipment 1 uses the grippers on the robotic arm 2 to continuously pick up the material on the material plate 3 and put it onto the grinding belt 6 or the grinding wheel 8 for rough and fine grinding operations. The entire grinding process is visualized and intelligent, requiring no manual intervention, which facilitates the improvement of the efficiency of batch grinding of standard parts.
[0019] The material plate 3 is a rectangular plate, and grooves for placing materials are evenly opened on the material plate 3. The material plate 3 can be disassembled and installed with the base by plugging and unplugging. The grinding belt 6 is stretched into a triangle by the drive wheel 5 and multiple driven wheels. The grinding belt 6 is set on both sides of the drive mechanism 4, and its width is smaller than the width of the dust baffle 7. The two dust baffles 7 are C-shaped, and the two dust baffles 7 can be disassembled and installed with the drive mechanism 4 by bolts.
[0020] The two grinding belts 6 on both sides of the drive mechanism 4 can simultaneously grind two workpieces at the same time, or grind them to different degrees. The dust baffles 7 on both sides can block the dust generated during grinding within the range of the two grinding belts 6, preventing contamination of the inner wall of the grinding equipment body 1, and allowing the dust to be transported towards the cleaning section 9.
[0021] The cleaning section 9 is equipped with a reciprocating screw 901 and a guide rail parallel to the axis of the reciprocating screw 901. The reciprocating screw 901 and the drive shaft 501 on the drive wheel 5 are driven by a sprocket. A sleeve 902 is fitted on the reciprocating screw 901. A ball bearing is installed inside the sleeve 902. The ball bearing rolls in a curved groove on the surface of the reciprocating screw 901. A suction head 903 is fixedly connected to the sleeve 902 and slidably mounted on the guide rail. Multiple suction nozzles are evenly arranged on the suction head 903. The suction head 903 is connected to the suction mechanism 10 through a hose. A pump and a drawer 11 are installed inside the suction mechanism 10. Buckles 12 are fixedly connected to both sides of the inner wall of the drawer 11. Activated carbon filter screen 13 can be slidably connected between the buckles 12. Activated carbon is evenly placed inside the activated carbon filter screen 13.
[0022] The reciprocating screw 901 on the cleaning section 9 drives the suction head 903 to move back and forth, absorbing the dust during grinding into the suction mechanism 10. The dust is then passed through the activated carbon filter 13. Regular cleaning of the activated carbon filter 13 is sufficient to ensure that the air inside the entire grinding equipment body 1 is clean.
[0023] Working principle of this utility model:
[0024] Refer to the instruction manual appendix Figures 1-3 First, evenly place the material to be ground in the groove on the material plate 3. Then, transport the material plate 3 to the base inside the main body 1 of the grinding equipment (by plugging and unplugging). Start the drive wheel 5 on the drive mechanism 4 and start running. Then, multiple driven wheels will also start running, and the grinding belt 6 will be tightened and run quickly.
[0025] Synchronously, the robotic arm 2 starts to continuously pick up the material from the material plate 3 and then grind it on the grinding belt 6 or the grinding wheel 8. The grinding belt 6 grinds finely, while the grinding wheel 8 grinds slightly coarser. The choice can be made according to actual needs.
[0026] During the continuous polishing process, the drive shaft 501 also rotates synchronously, causing the reciprocating screw 901 to rotate, which drives the sleeve 902 and the suction head 903 to move back and forth on the cleaning section 9. In other words, it can move within the polishing range, sucking the polishing dust or dirty air into the suction head 903, and then transporting it to the suction mechanism 10 through the hose.
[0027] The activated carbon placed on the activated carbon filter 13 inside the suction mechanism 10 filters out dirty air. The activated carbon filter 13 can be periodically removed for cleaning or replacement.
[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
