Technical Field
[0001] This utility model relates to the field of grinding equipment technology, specifically to a grinding equipment for processing metal mechanical parts. Background Technology
[0002] Most molds used for casting are composed of several parts, and the seams cannot be perfectly smooth, leaving small gaps. When the cast parts are produced, these gaps will have small raised edges, known as parting lines. Simply put, plastic parts and die-cast parts need to be molded in several parts, which are then assembled to form a closed space. The lines between these parts are the parting lines. Parting lines are essentially burrs produced by the molded product. Factories typically handle these burrs by grinding, mostly manually, because even similar products can vary between models. Grinding can be done using electric grinders, which have the advantage of grinding small amounts at a time, generally avoiding over-grinding, but are less efficient. Another method is to use a grinding machine, bringing the parting line close to the grinding stone. This method is more efficient. Chinese patent discloses a grinding and polishing device for metal mechanical parts (authorization announcement number CN114029810B). This patent technology discloses a grinding and polishing device for metal mechanical parts, belonging to the field of grinding equipment technology. The invention includes a frame, with several mounting rollers rotatably connected to both ends of the frame, and at least one set of mounting rollers at each end located below the frame. The frame also has a first motor, and the drive shaft of the first motor is connected to one of the mounting rollers at each end of the frame through gears and a transmission shaft. A grinding belt is sleeved between the mounting rollers at each end of the frame. Two sets of pilot wheels are provided at both ends of the bottom of the frame, and a fine grinding section is provided at the bottom of the frame between the two sets of grinding belts. This invention sets the grinding device into a two-part grinding structure of grinding belt and fine grinding section. The grinding belt is initially positioned under the action of the pilot wheels, grinding thicker burrs to near the product surface, and then fine grinding is performed by the fine grinding section, thereby avoiding over-grinding and not affecting the grinding efficiency. This patented technology solves the problem of excessive sanding causing missing material. It still uses a handheld sander with rotating sandpaper for sanding. This method is more efficient when the burrs on the parting line are thin and should not be overdone, but it is not effective for thicker burrs.
[0003] However, in the existing technology, when grinding mechanical parts with a grinding belt, prolonged grinding will reduce the durability of the grinding belt and reduce grinding efficiency. There is a need to solve the problem of quickly replacing the grinding belt that can quickly grind mechanical parts, which is currently available in the technology.
[0004] Therefore, those skilled in the art have provided a metal mechanical parts processing and grinding device to solve the problems mentioned in the background art. Utility Model Content

Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.
[0029] For examples, please refer to Figures 1-5 This embodiment provides a metal mechanical parts processing and grinding device, including: a grinding frame 1; a grinding structure 2 is installed inside the grinding frame 1, the grinding structure 2 includes an inner mounting frame 201 fixedly installed inside the grinding frame 1, and a limiting groove 202 is formed on the inner wall of the inner mounting frame 201; a positioning rail frame 203 is slidably limited inside the limiting groove 202, and a driven roller 205 is rotatably installed at one end of the front side of the positioning rail frame 203;
[0030] An active roller 209 is rotatably mounted on the inner side of the mounting frame 201 at the same horizontal position as the driven roller 205. One end of the active roller 209 is connected to a servo motor 210, and the active roller 209 is assembled on the inner side of the mounting frame 201 via the servo motor 210. A grinding positioning plate 204 is integrally fixed to the side wall of the positioning rail frame 203. A screw hole is opened inside the positioning rail frame 203, and an adjusting screw 207 is screwed in the screw hole. One end of the adjusting screw 207 is connected to a servo motor 208.
[0031] The servo motor 208 is fixedly installed inside the mounting frame 201 and is used to actively drive the adjusting screw 207 to rotate. A grinding belt 206 for grinding metal mechanical parts is sleeved between the driving roller 209 and the driven roller 205. The positioning rail frame 203 is located inside the grinding belt 206. A chip removal structure 3 is provided on the mounting frame 201. The chip removal structure 3 includes a chip suction hopper 301 fixedly installed on the outer wall of the mounting frame 201, and a chip suction pipe 302 is connected through the top of the chip suction hopper 301.
[0032] The end of the dust collection pipe 302 away from the dust collection hopper 301 is connected to a vacuum cleaner 303, and the discharge end of the vacuum cleaner 303 is connected to a dust collection box 304 installed on the inner frame 201. Side frame screw plates 4 are integrally fixed to the outer walls of the four corners of the grinding machine frame 1. Adjusting screws 5 are spirally driven on the inner side of the side frame screw plates 4. A support pad 7 is rotatably installed at the bottom end of the adjusting screw 5, and a cross handle 6 is fixedly mounted on the outer wall of the top end of the adjusting screw 5. A controller 8 is installed on the outer wall of the grinding machine frame 1.
[0033] According to the above embodiments, the working principle of this invention is as follows:
[0034] The distance between the driven roller 205 and the driving roller 209 can be adjusted according to the diameter of the grinding belt 206.
[0035] When replacing the grinding belt 206, the servo motor 208 is started. The servo motor 208 rotates counterclockwise to drive the adjusting screw 207, which moves the positioning rail 203 of the screw drive close to one end of the driving roller 209. This allows the grinding belt 206 to loosen between the driving roller 209 and the driven roller 205, making it easier to loosen the grinding belt 206 and replace it with a new one.
[0036] After the new grinding belt 206 is fitted between the drive roller 209 and the driven roller 205, the servo motor 208 is started clockwise to move the driven roller 205 away from the drive roller 209 and support the grinding belt 206 to complete the assembly.
[0037] When the grinding belt 206 moves, the servo motor 210 is started to rotate. The servo motor 210 drives the active roller 209 to rotate, so that the active roller 209 moves the grinding belt 206. When the metal mechanical parts are ground by the grinding belt 206, they can be ground by directly contacting the grinding belt 206.
[0038] The waste shavings from grinding metal mechanical parts can be collected by starting a vacuum cleaner 303. After the vacuum cleaner 303 is started, the suction power through the shavings hopper 301 will collect the metal waste shavings into the dust storage box 304, reducing the impact of metal waste shavings on the environment.
[0039] The adjusting screw 5 can adjust the horizontal angle of the grinding machine frame 1. By manually rotating the cross lever 6, the adjusting screw 5 is rotated, so that the adjusting screw 5 supports the support pad 7 on the ground.
