Description

Technical Field

[0001] This utility model relates to the field of grinding and polishing devices, and in particular to a grinding and polishing device for grinding media profile. Background Technology

[0002] Grinding media are materials used in the grinding process to contact materials and apply pressure and generate friction to achieve material refinement or surface processing. Common grinding media include steel balls, ceramic balls, and abrasive grains. In the research and development of grinding media, it is usually necessary to grind and polish the grinding media to remove its surface material and expose its cross-section, so as to facilitate the observation of the internal structural characteristics of the grinding media.

[0003] In the existing technology, traditional grinding and polishing devices mostly use unidirectional rotation for grinding operations. The grinding media and the grinding disc only form frictional contact in one direction. This not only results in low grinding efficiency and difficulty in achieving the ideal cross-sectional effect in a short time, but also easily leads to uneven cross-sections and insufficient polishing in some areas, thus affecting the observation effect of the cross-section of the grinding media. In addition, the structure of traditional grinding and polishing devices is relatively complex and the adjustment method is inconvenient, which increases the difficulty of operation for users.

[0004] Therefore, existing technologies have shortcomings and need to be improved. Utility Model Content

[0009] The rotary drive mechanism is mounted on the lifting seat and is connected to the fixed clamp to drive the fixed clamp to rotate. The fixed clamp is located above the grinding disc and is used to hold and fix the cylindrical grinding media.

[0010] Using the above technical solution, in the grinding media profile grinding and polishing device, the pressure handle mechanism includes a pressure handle handle, a connecting rod, a sliding bearing, and a spring;

[0011] The lifting seat is slidably connected to the guide slide rod via the sliding bearing, and the spring is located at the bottom of the lifting seat. The spring is used to apply an upward sliding force to the lifting seat.

The pressure handle is used to drive the lifting seat to slide downward when under pressure, so that the grinding medium in the fixed clamp abuts against the surface of the grinding disc.

[0013] Using the above technical solution, in the grinding media profile grinding and polishing device, the bottom of the machine base is provided with a grinding drive mechanism, which is used to drive the grinding disc to rotate. The grinding drive mechanism includes a first motor, a first driving pulley, a first driven pulley, and a first transmission belt.

[0019] The above technical solution includes a universal cooling pipe in the grinding media profile grinding and polishing device. The universal cooling pipe is located at the side end of the grinding disc and is used to deliver cooling liquid toward the grinding disc.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] The grinding disc of this invention can rotate at high speed under the action of the grinding drive mechanism.

It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component centrally located at the same time.

[0029] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0030] like Figures 1 to 3As shown in the figure, this utility model embodiment provides a grinding and polishing device for the cross-section of grinding media, including a base 1, a grinding disc 2, a support rod 3, a locking clamp 4, a guide slide rod 5, a lifting seat 6, a pressure handle mechanism 7, a rotary drive mechanism 8, and a fixing fixture 9. The grinding disc 2 is rotatably mounted on the base 1. The support rod 3 is located at the side end of the base 1. Two locking clamps 4 are respectively mounted vertically on the support rod 3. The guide slide rod 5 is located between the two locking clamps 4 and is used to adjust the position of the guide slide rod 5. The lifting seat 6 is slidably mounted on the guide slide rod 5. The pressure handle mechanism 7 is connected to the lifting seat 6 and is used to adjust the height of the lifting seat 6 relative to the guide slide rod 5. The rotary drive mechanism 8 is located on the lifting seat 6 and is connected to the fixing fixture 9 to drive the fixing fixture 9 to rotate. The fixing fixture 9 is located above the grinding disc 2 and is used to clamp and fix the columnar grinding media. The grinding disc 2 can rotate, and the grinding media is fixed in the fixed clamp 9. The rotation drive mechanism 8 can drive the grinding media to rotate in the opposite direction, thereby increasing the friction and impact between the grinding media and the grinding disc 2, effectively improving the grinding and polishing efficiency of the grinding media, thus exposing its internal structure more quickly and making the cross-section of the grinding media more uniform. In addition, the pressure handle mechanism 7 can adjust the height position of the lifting seat 6 to control the contact pressure between the grinding media and the grinding disc 2. With this setting, the user can adjust the contact state and pressure between the grinding media and the grinding disc 2 as needed, thereby adjusting the polishing depth of the grinding media.

[0031] like Figure 2As shown, the pressure handle mechanism 7 further includes a pressure handle 71, a connecting rod 72, a sliding bearing 73, and a spring 74. The lifting seat 6 is slidably connected to the guide slide rod 5 via the sliding bearing 73. The spring 74 is located at the bottom of the lifting seat 6 and is used to apply an upward sliding force to the lifting seat 6. The middle part of the pressure handle 71 is movably connected to the lifting seat 6 via a first pin 751. The end of the pressure handle 71 is movably connected to the top of the connecting rod 72 via a second pin 752. The bottom end of the connecting rod 72 is connected to the locking clamp 4 via a third pin 753. The pressure handle 71 is used to drive the lifting seat 6 to slide downward when under pressure, so that the grinding medium in the fixed clamp 9 abuts against the surface of the grinding disc 2. When grinding and polishing the grinding media is required, the user can pull down the pressure handle 71. Through the transmission action of the connecting rod 72, the lifting seat 6 can be driven to slide downward against the elastic force of the spring 74. At this time, the grinding media gradually presses down onto the surface of the grinding disc 2. By adjusting the force of the pressure handle 71, the user can control the contact pressure between the grinding media and the grinding disc 2. After polishing is completed, the user can release the pressure handle 71. The spring 74 pushes the lifting seat 6 upward through its elastic force, so that the grinding media returns to its initial position. The sliding bearing 73 prevents the lifting seat 6 from shifting laterally.

[0032] like Figure 3 As shown, further, the bottom of the base 1 is provided with a grinding drive mechanism 20, which is used to drive the grinding disc 2 to rotate. The grinding drive mechanism 20 includes a first motor 201, a first driving pulley 202, a first driven pulley 203, and a first transmission belt 204. The first motor 201 is located inside the base 1, with its output end facing downwards and connected to the first driving pulley 202. The bottom of the grinding disc 2 is connected to the first driven pulley 203 through a rotating shaft. The first driving pulley 202 and the first driven pulley 203 are connected by the first transmission belt 204.

[0033] like Figure 1 and Figure 2 As shown, the rotary drive mechanism 8 further includes a second motor 81, a second driving pulley 82, a second driven pulley 83, and a second transmission belt 84. The second motor 81 is mounted on the lifting seat 6. The output shaft of the second motor 81 is connected to the second driving pulley 82. The second driven pulley 83 is connected to the fixed clamp 9 through a connecting shaft 85. The second driving pulley 82 and the second driven pulley 83 are connected by the second transmission belt 84.

[0034] like Figure 2As shown, the locking clamp 4 further includes a clamping rod seat 41 and a locking knob 42. The clamping rod seat 41 is provided with a clamping hole that is sleeved and connected to the support rod 3. The locking knob 42 passes through the clamping rod seat 41 and locks against the support rod 3. This arrangement makes it easy for the user to adjust the initial position of the fixing clamp 9 so as to control the contact position and pressure between the grinding medium and the grinding disc 2 according to different grinding depths.

[0035] like Figure 2 As shown, the end of the pressure handle 71 is provided with an anti-slip sleeve 711 for easy gripping. The anti-slip sleeve 711 allows the user to grip the pressure handle 71 more firmly when applying force, avoiding slippage during operation and improving grip comfort.

[0036] like Figure 1 As shown, it further includes a universal cooling pipe 11, which is located at the side end of the grinding disc 2. The universal cooling pipe 11 is used to deliver cooling liquid toward the grinding disc 2. During the grinding and polishing process, a large amount of friction will be generated between the grinding disc 2 and the grinding medium, which will cause the temperature to rise. The cooling liquid can remove the heat generated between the surface of the grinding disc 2 and the grinding medium in time, prevent local overheating, and thus improve the stability of the grinding process.

[0037] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
