Description

Technical Field

[0001] This utility model relates to the field of metal parts processing technology, and in particular to a grinding device for precision metal parts. Background Technology

[0002] Grinding equipment for metal parts is an important piece of equipment in the field of precision manufacturing. It is mainly used to polish, deburr, and finish the surface of metal parts to improve their surface accuracy, smoothness, and assembly compatibility. It is widely used in industries such as aerospace, automotive manufacturing, and precision instruments. By driving the grinding components to move relative to the metal parts, it achieves precise surface processing of the metal parts, which is a key step in ensuring the quality of metal parts.

[0003] Currently, some metal grinding devices on the market adopt a structure where a single grinding component corresponds to a single fixing mechanism. That is, one grinding component can only grind one metal component on the fixing mechanism. When the grinding component is grinding the current metal component, other metal components to be processed must wait for the current grinding to be completed before they can be fixed. The ground metal components must also wait for the grinding component to be idle before they can be removed. This results in the loading and unloading and grinding processes not being able to run in parallel, which greatly reduces processing efficiency. At the same time, the frequent waiting time increases the equipment idle rate, which is not conducive to mass production and cannot meet the high-efficiency processing requirements of the precision manufacturing field. In order to solve the above problems, this utility model proposes a precision metal grinding device. Utility Model Content

Detailed Implementation

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] like Figure 1-5 As shown, a precision metal parts grinding device includes a grinding box 1, a mounting bracket 6 and a rotating disk 7. A first motor 8 is provided on the rotating disk 7. The rotating disk 7 includes a disk body and a rod body. The output shaft of the first motor 8 is fixedly connected to the first grinding disk. The connection method between the first motor 8 and the first grinding disk is the same as the installation method of the prior art. A mounting cylinder 4 is rotatably connected to the bottom of the grinding box 1. A mounting disk 2 is fixedly connected to the upper end of the mounting cylinder 4.

[0026] The upper end of the mounting plate 2 is provided with multiple fixing mechanisms for fixing metal parts. The fixing mechanism includes a mounting frame 5 fixedly connected to the mounting plate 2. The mounting frame 5 is provided with a reciprocating screw 15 and a moving block 12. The upper end of the moving block 12 is provided with a fixing frame 14. The bottom of the fixing frame 14 is fixedly connected with a second electric push rod 9. The second electric push rod 9 can be powered by a slip ring (conductive slip ring) or wireless power supply technology. The output end of the second electric push rod 9 is fixedly connected with a clamping plate 10. The upper end of the clamping plate 10 is provided with multiple sliding grooves. Sliding blocks are slidably connected in the sliding grooves. Bolts are passed through the upper end of the sliding blocks. The bottom of the grinding box 1 is installed with a first electric push rod 3 through a mounting rod (shown in the figure). The output shaft of the first electric push rod 3 is fixedly connected with a third motor 17. The output shaft of the third motor 17 is fixedly connected with a limit block 16. The side wall of the reciprocating screw 15 is provided with a limit groove that cooperates with the limit block 16.

[0027] The grinding box 1 is equipped with a drive mechanism for driving the mounting plate 2. The drive mechanism includes a fourth motor 21 (the output shaft can be self-locking) fixedly connected to the bottom of the grinding box 1. The output shaft of the fourth motor 21 and the side wall of the mounting cylinder 4 are respectively provided with a first gear and a second gear. The teeth and meshing details of the first gear and the second gear are not shown in the figure. In fact, the two mesh with each other. A water baffle is fixedly connected to the bottom of the grinding box 1. The water baffle is set directly opposite the fourth motor 21. The first electric push rod 3, the second electric push rod 9, the third motor 17, and the fourth motor 21 are all waterproofed. The outer surface can be waterproof shell or other waterproof means.

[0028] In this utility model, the rotating disk 7 is rotatably connected to the mounting bracket 6. The upper end of the mounting bracket 6 is fixedly connected to a fifth motor 22 (the output shaft rotation range does not exceed 360 degrees, and the output shaft can rotate forward and backward and self-lock). The output shaft of the fifth motor 22 and the side wall of the rotating disk 7 are respectively fixedly connected to a third gear and a fourth gear. The teeth and meshing details of the third gear and the fourth gear are not shown in the figure. In fact, the two mesh with each other. The rotating disk 7 is equipped with a second motor 11. The output shaft of the second motor 11 is fixedly connected to a second grinding disk. The grinding precision of the two second grinding disks is different. The grinding precision of the first grinding disk and the two second grinding disks increases (or decreases) sequentially. The first grinding disk and the two second grinding disks can provide grinding functions of different precision. Metal parts can be processed progressively by passing through different grinding disks in the order of 'low precision → high precision'.

[0029] In this utility model, a liquid pump 18 is fixedly connected to the upper end of the mounting bracket 6. A water spray pipe is connected to the water outlet of the liquid pump 18. A drain pipe 20 is connected to the side wall of the grinding box 1. The liquid pump 18 sprays coolant or clean water to the grinding area through the water spray pipe, which effectively reduces the temperature during the grinding process and prevents the metal parts from deforming due to high temperature or the grinding disc from wearing out. The drain pipe 20 discharges sewage in time to ensure a clean grinding environment.

[0030] In this utility model, a guide groove 19 is provided at the bottom of the grinding box 1, and an inclined surface is provided at the bottom of the grinding box 1. The guide groove 19 collects the wastewater and debris generated during grinding. The inclined surface structure uses gravity to accelerate the flow of wastewater to the drain pipe 20, thereby preventing wastewater from accumulating in the grinding box 1 and improving the sewage discharge efficiency.

[0031] In this utility model, protective frames 13 are fixedly connected to both sides of the movable block 12. The protective frames 13 are slidably connected to the mounting frame 5. The protective frames 13 can prevent grinding debris and sewage from contacting the reciprocating screw 15, thus avoiding contamination or wear of the screw and ensuring its transmission accuracy and service life. The slidable connection with the mounting frame 5 does not affect the normal movement of the movable block 12, and the structural design is reasonable.

[0032] In this utility model, the upper end of the mounting plate 2 is provided with multiple through slots, which are equally spaced. The through slots reduce the weight of the mounting plate 2 and facilitate the passage of debris and wastewater generated during grinding, preventing them from accumulating on the surface of the mounting plate 2 and reducing the cleaning burden. The equal spacing ensures that the structure of the mounting plate 2 is subjected to uniform force, and avoids the instability caused by the shift of the center of gravity when rotating.

[0033] In the initial state, the inlet of liquid pump 18 is connected to an external water source through a pipe.

[0034] In use, multiple fixing mechanisms (corresponding to multiple workstations) are distributed along the circumference of the mounting plate 2. The rightmost workstation is the loading workstation, where the operator can fix the unpolished metal parts by means of the fixing mechanism (the second electric push rod 9 drives the clamping plate 10, and the sliding block and bolts cooperate). The last workstation is the unloading workstation, where the polished metal parts can be unfixed and removed. After the fourth motor 21 is started, it drives the mounting cylinder 4 to rotate through the meshing of the first gear and the second gear, which in turn drives the mounting plate 2 to rotate, so that the loaded metal parts flow to the bottom of the first polishing plate (driven by the first motor 8). The output of the first electric push rod 3 can control the limit block 16 of the third motor 17 to engage with the limit groove of the reciprocating screw 15. The output end of the second electric push rod 9 extends, pushing the metal parts to contact the first polishing plate. The third motor 17 drives the reciprocating screw 15 to rotate, and the metal parts swing left and right to be polished by the first polishing plate. The "loading-polishing-unloading" is carried out simultaneously, without waiting for a single process to be completed, which greatly improves efficiency.

[0035] The equipment can perform progressive precision grinding. The first grinding disc on the rotating disk 7 and the two second grinding discs have different grinding precision (e.g., the first grinding disc is for coarse grinding and the second grinding disc is for fine grinding). The fifth motor 22 drives the rotating disk 7 to rotate through the third gear and the fourth gear. The grinding disc of the corresponding precision can be adjusted to be above the metal part according to the processing requirements. When the metal part rotates with the mounting disk 2 to different grinding positions, it contacts the grinding discs of different precision in sequence, realizing progressive processing from low precision to high precision and ensuring the surface quality of the metal part.

[0036] In addition, the rotation of the mounting plate 2 is automatically completed by the fourth motor 21 through gear transmission, without the need for manual pushing. The rotation angle can be precisely controlled by the controller to ensure that the metal parts are accurately aligned with the grinding plate and improve the processing accuracy. At the same time, the first electric push rod 3 can control the engagement / disengagement of the limit block 16 of the third motor 17 and the limit groove of the reciprocating screw 15, so that a single third motor 17 can drive multiple fixed mechanisms to work, thereby reducing the number of drive components.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
