Description

Technical Field

[0001] This utility model relates to the field of metal parts grinding technology, and in particular to an automated metal parts grinding equipment. Background Technology

[0002] Grinding of automotive sheet metal parts refers to the precision machining process of the surface of stamped and welded metal sheets using tools such as sandpaper, grinding wheels, and polishing wheels. Its purpose is to remove defects such as burrs, oxide layers, and weld slag, correct dimensional tolerances, and improve surface roughness to achieve the geometric accuracy and finish required by the drawings. It is a key process for improving the assembly quality of parts, coating adhesion, and product aesthetics, and is widely used in the production of exterior body panels such as car doors and hoods.

[0003] In current automotive repair processes, sheet metal parts need to be sanded. Most existing auto repair shops use manual sanding, where workers typically use hand-held sanding equipment to sand the sheet metal. During the sanding process, the worker needs to fix the sheet metal in place beforehand or hold the sheet metal in place with one hand while sanding with the other.

[0004] Based on the aforementioned technologies, the applicant believes that manual grinding is inefficient, the sheet metal is unstable and prone to errors, and manual hand-held grinding equipment poses certain safety hazards. In response to these issues, we have developed an automated grinding equipment for metal parts. Utility Model Content

[0005] This utility model discloses an automated grinding equipment for metal parts, which aims to solve the technical problems of low grinding efficiency, unstable plate fixing, easy grinding errors, and certain safety hazards of manual hand-held grinding equipment.

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

[0007] An automated metal parts grinding device includes a base plate, with support frames symmetrically fixedly connected to the bottom of the base plate, a fixed frame fixedly connected to one side of the top of the base plate, and a production mechanism fixedly connected to the top of the base plate. The production mechanism includes a positioning component and a grinding component, which cooperate with each other. The positioning component includes a cylinder fixedly connected to the back of the fixed frame, and positioning frames symmetrically fixedly connected to the outer side of the fixed frame. Both positioning frames are fixedly connected to the top of the base plate. The fixed frame has symmetrically formed telescopic grooves inside, and positioning plates are slidably connected inside each of the two telescopic grooves. The telescopic end of the cylinder extends into the interior of the fixed frame and is fixedly connected to a rotating block. A rotating plate is rotatably connected inside the rotating block, and the two rotating plates are rotatably connected to the top of the two positioning plates respectively. A U-shaped metal part body is placed on the top of the base plate.

[0008] The production mechanism allows for precise grinding of workpieces without requiring manual grinding equipment. This results in high grinding efficiency, good grinding effect, and avoids the safety hazards associated with manual grinding. The structure is simple and highly practical.

[0009] In a preferred embodiment, the grinding assembly includes an adjustment groove located inside a base plate. A displacement motor is fixedly connected to the outer side of the base plate. A threaded rod is rotatably connected inside the adjustment groove. One end of the threaded rod is fixedly connected to the output end of the displacement motor. A displacement block is threadedly connected to the outer side of the threaded rod. A grinding motor is fixedly connected to the bottom of the displacement block. The output end of the grinding motor extends above the displacement block and is fixedly connected to a grinding roller.

[0010] The grinding assembly uses a displacement motor to drive a threaded rod to rotate, which in turn moves a displacement block within an adjustment groove. This allows the grinding motor to drive the grinding roller to automatically grind the metal parts. The design of the adjustment groove and the threaded rod ensures the smoothness and precision of the grinding process, thereby improving the processing quality.

[0011] In a preferred embodiment, rubber positioning blocks are fixedly connected to the inner walls of both positioning frames, and the rubber positioning blocks and positioning plates are used in cooperation with each other.

[0012] The rubber positioning blocks on the inner wall of the positioning frame work together with the positioning plate to enhance clamping stability and avoid rigid contact that could damage the surface of metal parts, thereby improving the yield of finished products.

[0013] In a preferred embodiment, a stabilizing groove is provided on one side of the inner wall of the adjusting groove, and a limiting slider is slidably connected inside the stabilizing groove. The limiting slider is fixedly connected to the displacement block.

[0014] The cooperation between the stabilizing groove and the limiting slider restricts the movement trajectory of the displacement block, prevents deviation during grinding, ensures the linear motion accuracy of the grinding roller, and further improves processing consistency.

[0015] In a preferred embodiment, both the displacement motor and the grinding motor are fixedly connected to protective covers on their outer sides, and the interiors of both protective covers are provided with heat dissipation slots at equal intervals for heat dissipation.

[0016] The protective covers and heat dissipation slots on the outside of the displacement motor and grinding motor effectively prevent dust from entering the motor, while the heat dissipation slots optimize heat dissipation performance and extend the service life of the motor.

[0017] In a preferred embodiment, a controller is fixedly connected to the top side of the base plate, and the cylinder, displacement motor and grinding motor are all electrically connected to the controller.

[0018] The controller centrally controls the cylinder, displacement motor, and grinding motor, enabling automated operation of the equipment, reducing the need for manual intervention, and improving production efficiency and ease of operation.

[0019] The automated grinding equipment for metal parts provided by this utility model has the following advantages:

[0020] Firstly, the production mechanism allows for precise grinding of workpieces without requiring workers to manually operate the grinding equipment. This results in higher grinding efficiency, better grinding effects, and avoids the safety hazards associated with manual grinding. The structure is simple and highly practical.

[0021] Secondly, the rubber positioning blocks on the inner wall of the positioning frame work in conjunction with the positioning plate to enhance clamping stability and prevent rigid contact damage to the surface of metal parts, thereby improving the yield of finished products. The stable cooperation between the slide rail and the limiting slider restricts the movement trajectory of the displacement block, preventing deviation during grinding and ensuring the linear motion accuracy of the grinding roller, further improving processing consistency. The protective covers and heat dissipation grooves on the outside of the displacement motor and grinding motor effectively prevent dust from entering the motor, while the heat dissipation grooves optimize heat dissipation performance and extend the motor's service life. The controller centrally controls the cylinder, displacement motor, and grinding motor, realizing automated operation of the equipment, reducing the need for manual intervention, and improving production efficiency and ease of operation.

[0030] The automated grinding equipment for metal parts disclosed in this utility model is mainly used in the grinding of metal parts.

[0031] Reference Figure 1 - Figure 6An automated metal parts grinding equipment includes a base plate 1, a support frame 2 symmetrically fixedly connected to the bottom of the base plate 1, a fixed frame 3 fixedly connected to one side of the top of the base plate 1, and a production mechanism fixedly connected to the top of the base plate 1. The production mechanism includes a positioning component and a grinding component, which cooperate with each other. The positioning component includes a cylinder 41, which is fixedly connected to the back of the fixed frame 3. A positioning frame 42 is symmetrically fixedly connected to the outside of the fixed frame 3. Both positioning frames 42 are fixedly connected to the top of the base plate 1. The fixed frame 3 has symmetrically opened telescopic grooves 43 inside. Both telescopic grooves 43 are slidably connected to the inside of the two telescopic grooves 43. The telescopic end of the cylinder 41 extends into the inside of the fixed frame 3 and is fixedly connected to a rotating block 46. A rotating plate 45 is rotatably connected inside the rotating block 46. The two rotating plates 45 are rotatably connected to the top of the two positioning plates 44 respectively. A U-shaped metal part body 7 is placed on the top of the base plate 1. The grinding assembly includes an adjustment groove 51, which is located inside the base plate 1. A displacement motor 53 is fixedly connected to the outside of the base plate 1. A threaded rod 54 is rotatably connected inside the adjustment groove 51. One end of the threaded rod 54 is fixedly connected to the output end of the displacement motor 53. A displacement block 55 is threadedly connected to the outside of the threaded rod 54. A grinding motor 57 is fixedly connected to the bottom of the displacement block 55. The output end of the grinding motor 57 extends above the displacement block 55 and is fixedly connected to a grinding roller 56.

[0032] In this embodiment: When the equipment is working, the main body 7 of the metal component is first placed on the base plate 1. The controller 6 starts the cylinder 41 to push the rotating block 46 to move closer to the plate, and pushes the rotating plate 45 to make the positioning plate 44 slide along the telescopic groove 43. The rubber positioning block 47 clamps the two ends of the plate. Then, the displacement motor 53 drives the threaded rod 54 to rotate, so that the displacement block 55 drives the grinding motor 57 and the grinding roller 56 to move along the adjustment groove 51. The grinding motor 57 starts and drives the grinding roller 56 to rotate. Through the set production mechanism, the workpiece can be precisely ground without the need for the staff to hold the grinding equipment. The grinding efficiency is high, the grinding effect is good, and the safety hazards of manual grinding are avoided. The structure is simple and the practicality is strong.

[0033] In the above technical solution, considering that manual sanding is inefficient, the board is not easily fixed, and errors are prone to occur, and that hand-held sanding equipment poses certain safety hazards, the specific operation is as follows to solve these problems:

[0034] Reference Figure 1 - Figure 6In a preferred embodiment, rubber positioning blocks 47 are fixedly connected to the inner walls of both positioning frames 42, and the rubber positioning blocks 47 and positioning plates 44 cooperate with each other. A stabilizing slide groove 52 is provided on one side of the inner wall of the adjusting groove 51, and a limiting slider 58 is slidably connected inside the stabilizing slide groove 52. The limiting slider 58 is fixedly connected to the displacement block 55. Protective covers are fixedly connected to the outer sides of the displacement motor 53 and the grinding motor 57, and heat dissipation grooves for heat dissipation are provided at equal intervals inside the two protective covers. A controller 6 is fixedly connected to the top side of the base plate 1, and the cylinder 41, the displacement motor 53 and the grinding motor 57 are all electrically connected to the controller 6.

[0035] In this embodiment, the rubber positioning block 47 on the inner wall of the positioning frame 42 works in conjunction with the positioning plate 44 to enhance clamping stability and prevent rigid contact damage to the surface of metal parts, thereby improving the yield of finished products. The stable cooperation between the slide groove 52 and the limiting slider 58 restricts the movement trajectory of the displacement block 55, preventing deviation during grinding and ensuring the linear motion accuracy of the grinding roller 56, further improving processing consistency. The protective covers and heat dissipation grooves on the outside of the displacement motor 53 and the grinding motor 57 effectively prevent dust from entering the motor, while optimizing heat dissipation performance through the heat dissipation grooves to extend the motor's service life. The controller 6 centrally controls the cylinder 41, the displacement motor 53, and the grinding motor 57, realizing automated operation of the equipment, reducing the need for manual intervention, and improving production efficiency and ease of operation.

[0036] Working principle: When the equipment is working, the main body of the metal component 7 is first placed on the base plate 1. The controller 6 starts the cylinder 41 to push the rotating block 46 to move closer to the plate, and pushes the rotating plate 45 to make the positioning plate 44 slide along the telescopic groove 43. The rubber positioning block 47 clamps the two ends of the plate. Then, the displacement motor 53 drives the threaded rod 54 to rotate, so that the displacement block 55 drives the grinding motor 57 and the grinding roller 56 to move along the adjustment groove 51. The grinding motor 57 starts and drives the grinding roller 56 to rotate, and performs precise grinding on the workpiece. The whole process is automatically controlled by the controller 6 to ensure efficient and stable processing results.
