Description

Technical Field

[0001] The present invention relates to the technical field of polishing devices, and in particular to a surface polishing device for mechanical parts. Background Art

[0002] Grinding is a type of surface modification technology. It generally refers to a processing method that uses rough objects (such as sandpaper containing high-hardness particles) to change the physical properties of the material surface through friction. The main purpose is to obtain a specific surface roughness.

[0003] Grinding is widely used in the production process. Different grinding levels are divided into coarse grinding, fine grinding, superfine grinding, polishing and other processes. Most of the above grinding processes are carried out at different workstations. Each time the workpiece's workstation changes, it needs to be clamped again, which reduces grinding efficiency. Summary of the Invention

[0004] To solve the above problems, the present invention discloses a surface grinding device for mechanical parts, comprising a work platform, wherein a plurality of grinding mechanisms are provided on one side of the upper end of the work platform, wherein the grinding mechanism comprises a second guide rail, a second movable platform is provided on the second guide rail in a sliding manner, a drive motor is provided on the second movable platform, and a grinding disc is fixedly connected to the output end of the drive motor. The drive motor is started to drive the grinding disc to rotate and perform the grinding operation. The purpose of providing multiple grinding mechanisms is to be able to install grinding discs of different specifications, so that the workpiece can be clamped at one time to complete multiple grinding processes, such as rough grinding, fine grinding, polishing, etc.

[0005] A first guide rail with an annular structure is fixedly connected to the other side of the work platform. Several first movable platforms are slidably mounted on the first guide rail. Linear motors are installed on the first guide rail and the first movable platforms to enable movement of the first movable platforms. The linear motors enable the first movable platforms to move on the first guide rail. The workpiece is fixedly connected to the first movable platform and, as the first movable platform moves, it sequentially passes through each grinding disc to complete the grinding process.

[0006] Preferably, the side wall of the driving motor is fixedly connected to a motor support, and the lower part of the motor support is fixedly connected to the second mobile platform. The driving motor is fixedly connected to the second mobile platform through the motor support.

[0007] Preferably, the second movable platform is threadedly connected with a fixing bolt, the end of which abuts against the upper end of the second guide rail. According to the current operation needs and the shape of the workpiece, the fixing bolt can be loosened to slide the second movable platform to control the position of the grinding disc.

[0008] Preferably, a negative pressure box is fixedly connected to the lower end of the work platform, a drawer-type dust collection box is provided at the lower part of the negative pressure box, and an opening is provided at the upper end of the work platform, the opening is connected to the negative pressure box, and the opening is located directly below the grinding disc in the working state. Grinding is a subtractive manufacturing process, so a large amount of dust is generated during the operation, polluting the environment. Therefore, a negative pressure box is provided. The dust generated by grinding enters the negative pressure box through the opening and eventually falls into the dust collection box.

[0009] Preferably, an exhaust fan is fixedly connected to the side wall of the negative pressure box, and a dust filter is provided on one side of the exhaust fan. When the exhaust fan is in operation, negative pressure is generated in the negative pressure box, thereby sucking dust generated by grinding into the negative pressure box at the opening. At the same time, the dust filter is provided to block dust and prevent it from escaping from the exhaust fan.

[0010] Furthermore, a partition is vertically fixedly connected to the upper part of the negative pressure box, and the dust filter is fixedly connected to the lower part of the partition, so that the dust filter and the partition separate the negative pressure box into two chambers, namely the dust chamber and the exhaust chamber. Dust enters the negative pressure box directly into the dust chamber and eventually falls into the dust collection box, while the exhaust fan and the dust chamber are directly connected. This setting can extend the clogging cycle of the dust filter.

[0011] Preferably, a bracket is fixedly connected to the lower end of the working platform. The bracket is assembled from a plurality of square steels and is used to support the working platform.

[0012] Preferably, a clamp is fixedly connected to the upper end of the first movable platform, and the clamp is used to clamp and fix the workpiece to prevent the workpiece from loosening during the grinding operation.

[0013] The beneficial effects of the present invention are as follows:

[0014] 1. Multiple grinding mechanisms are provided, and each grinding mechanism is provided with grinding discs of different specifications. The workpiece is clamped on the first mobile platform. As the first mobile platform moves, the workpiece passes through grinding discs of different specifications in turn to achieve different grinding processes. That is, in one clamping process, multiple grinding needs can be achieved, which greatly improves the grinding efficiency.

[0015] 2. A negative pressure box is provided under the working platform, and an exhaust fan is provided on the side wall of the negative pressure box. Therefore, the dust generated by grinding is sucked into the negative pressure box from the opening and falls into the dust collecting box, which not only reduces the air pollution generated during the grinding process, but also facilitates the centralized treatment of the dust in the dust collecting box.

[0024] like Figures 1 to 4 As shown, a surface grinding device for mechanical parts includes a working platform 5, which is a rectangular plate. Several grinding mechanisms 2 are arranged on one side of the upper end of the working platform 5. The grinding mechanisms 2 are arranged side by side, and multiple grinding mechanisms 2 are used to achieve different grinding accuracy requirements, which can meet the needs of multiple grinding processes by clamping the workpiece once. The grinding mechanism 2 includes a second guide rail 21, which is a straight guide rail, and countersunk holes are respectively provided at both ends of the second guide rail 21, and are fixed to the working platform 5 with bolts. A second movable platform 22 is slidingly provided on the second guide rail 21, and a driving motor 24 is provided on the second movable platform 22. The output end of the driving motor 24 is fixedly connected to a grinding disc 25. Starting the driving motor 24 drives the grinding disc 25 to rotate, and the workpiece is ground. At the same time, the grinding disc 25 is provided with a variety of specifications, which can achieve rough grinding, fine grinding, polishing, etc.

[0025] A first guide rail 7 with an annular structure is fixedly connected to the other side of the work platform 5. Several first movable platforms 8 are slidably mounted on the first guide rail 7. Specifically, the first movable platforms 8 can slide reciprocally on the first guide rail 7. A workpiece is placed on the first movable platform 8. As the first movable platform 8 moves, the workpiece passes through the polishing mechanism 2 in sequence, achieving polishing of different specifications. Linear motors are installed on the first guide rail 7 and the first movable platform 8 to achieve movement of the first movable platform 8. Specifically, coils and magnets are installed on the first guide rail 7 or the first movable platform 8. The controllable magnetic fields generated by the coils and magnets interact with each other, thereby driving the first movable platform 8 to move.

[0026] The side wall of the drive motor 24 is fixedly connected to the motor support 23, and the lower part of the motor support 23 is fixedly connected to the second mobile platform 22. The motor support 23 is used to support and fix the drive motor 24. At the same time, the lower part of the motor support 23 is interspersed with bolts, which are fixedly connected to the second mobile platform 22.

[0027] A fixing bolt 26 is threadedly connected to the second movable platform 22, and the end of the fixing bolt 26 abuts the upper end of the second guide rail 21. Loosening the fixing bolt 26 allows the second movable platform 22 to slide. When the shape of the workpiece to be polished requires adjusting the position of the polishing disc 25, the second movable platform 22 can be slid. When the polishing mechanism 2 needs to be operated, the second movable platform 22 can be slid away from the workpiece.

[0028] The lower end of the working platform 5 is fixedly connected to a negative pressure box 4, which is a rectangular box. A drawer-type ash box 3 is provided at the lower part of the negative pressure box 4. The ash box 3 has the same structure as the drawer. An opening 6 is provided at the upper end of the working platform 5. The opening 6 is connected to the negative pressure box 4, and the opening 6 is located directly below the grinding disc 25 in the working state. During the grinding operation, dust will be generated, which will cause air pollution. The dust in the grinding process will enter the negative pressure box 4 through the opening 6, reducing air pollution.

[0029] An exhaust fan 10 is fixedly connected to the side wall of the negative pressure box 4. When the exhaust fan 10 is turned on, it extracts the air in the negative pressure box 4, creating a negative pressure inside the negative pressure box 4. That is, suction is generated at the opening 6, which draws the generated dust into the negative pressure box 4 to collect the dust. A dust filter is provided on one side of the exhaust fan 10. The dust filter not only exhausts the air in the negative pressure box 4 but also blocks the dust to prevent it from being discharged from the exhaust fan 10.

[0030] The lower end of the work platform 5 is fixedly connected with a bracket 1. The bracket 1 is a rectangular parallelepiped frame composed of a plurality of square tubes, which supports the work platform 5.

[0031] The upper end of the first mobile platform 8 is fixedly connected with a clamp 9. The clamp 9 can be made as needed according to the shape of the workpiece. The clamp 9 is used to fix the workpiece and keep the workpiece position stable during the grinding process.

[0032] The technical means disclosed in the solution of the present invention are not limited to the technical means disclosed in the above-mentioned embodiment, but also include technical solutions composed of any combination of the above technical features.
