Description

Technical Field

[0001] The utility model relates to the technical field of grinding discs, in particular to an impact-resistant grinding disc. Background Art

[0002] A grinding disc is a tool used for grinding and polishing operations. It is usually made of metal or other hard materials with abrasive particles on the surface. Grinding discs are widely used in industrial manufacturing and maintenance processes to improve the surface quality of workpieces, remove burrs, or prepare the surface for subsequent coating or bonding processes.

[0003] For example, an impact-resistant grinding disc disclosed in Chinese patent announcement number (CN220531781U) relates to the technical field of ball mill liner grinding discs, and specifically includes a rubber plate, an arched body structure that bulges upward in the middle of the rubber plate; a rectangular groove is provided in the middle of the bottom surface of the rubber plate, and rectangular cavities extending toward the inside of the rubber plate are provided on both sides of the top of the rectangular groove; the utility model also includes a metal plate placed in the rectangular cavity. When the utility model is in use, a metal plate is provided inside the rubber plate, and the metal plate can strengthen the strength of the rubber plate. At the same time, the rubber plate can play a role in resisting impact and tumbling materials. Since the grinding disc installed in the drum is made of rubber, it can protect the glass from direct collision with the metal during the grinding process, thereby protecting the glass.

[0004] However, the above patent still has the problem of poor impact resistance of the grinding disc. For example, in the above patent, a structure such as a rubber plate with an edge is set at the connection of the grinding disc to alleviate the impact force caused by the grinding contact between the object and the grinding disc. However, the rubber plate used alone in this method has a poor impact buffering effect, and the grinding disc will still be damaged after long-term use. Utility Model Content

[0006] To achieve the above object, the utility model provides the following technical solutions: an impact-resistant grinding disc, comprising a grinding disc main body, a protective mechanism for improving the impact resistance effect is provided on the lower surface of the grinding disc main body, and support mechanisms for adjusting and supporting the grinding disc to prevent excessive deviation are provided at the four corners of the upper surface of the protective mechanism;

[0007] The protective mechanism includes a fixing plate, two connecting bolts, a connecting plate, a rubber pad, a plug-in block, a support frame and a buffer. The fixing plate is fixed to the lower surface of the grinding disc body, and the two connecting bolts are respectively fixed to the left and right sides of the lower surface of the fixing plate. The connecting plate is slidably connected to the outside of the two connecting bolts, and the rubber pad is sleeved on the outside of the two connecting bolts and is located between the opposite sides of the fixing plate and the connecting plate.

The buffer is arranged on the inner bottom wall of the support frame to increase the elastic impact resistance effect, and a mounting plate is fixed to the lower surface of the support frame.

[0008] Furthermore, the buffer component includes a plurality of support springs fixed to the inner bottom wall of the support frame, and a top plate is fixed to the upper surface of the plurality of support springs.

[0009] Furthermore, a plug interface is provided on the back of the support frame, and the support frame is slidably connected to the outer side of the plug block through the plug interface.

[0010] Furthermore, the cross-sectional shape of the plug-in block is T-shaped, and the width of the top plate is equal to the length of the plug-in block.

[0011] Furthermore, outer sides of the two connecting bolts are threadedly connected with locking nuts.

[0012] Furthermore, the support mechanism includes four adjusting screws, four threaded sleeves and four soft cushion blocks. The four adjusting screws are respectively fixed to the four corners of the upper surface of the mounting plate, the four threaded sleeves are respectively threadedly connected to the outside of the four adjusting screws, and the four soft cushion blocks are respectively connected to the top of the four threaded sleeves.

[0013] Furthermore, the diameter of the cushion block is greater than the diameter of the threaded sleeve, and the length of the threaded sleeve is equal to the length of the adjusting screw.

[0014] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0015] 1. The impact-resistant grinding disc is provided with a protective mechanism. The fixing plate ensures the connection between the entire protective mechanism and the grinding disc body. The connecting bolts connect the fixing plate and the connecting plate through the connecting bolts. When impacted, there is a certain displacement, thereby absorbing and dispersing the impact force. The rubber pad plays a buffering role. The plug-in block is used to enhance the stability of the connecting plate and serves as a connection point of the support frame. The sliding connection of the support frame allows a certain degree of displacement when impacted, thereby increasing the impact resistance of the entire protective mechanism. The buffer increases the elastic impact resistance effect, and the spring can provide restoring force to help the system quickly return to its original state after impact.

[0016] 2. The impact-resistant grinding disc is provided with a supporting mechanism. According to the working requirements of the grinding disc, the adjusting screw is positioned to a suitable position to determine the height and angle of the supporting point. The adjusting screw is rotated to adjust its extended length, thereby changing the distance between the supporting mechanism and the grinding disc body to ensure that the supporting mechanism will not loosen during the grinding process. During the grinding process, if the grinding disc is impacted or vibrated, the soft pad block and the supporting spring will absorb these impacts to reduce the impact on the grinding disc. The supporting spring helps the supporting mechanism to return to its original position after the impact to maintain the stability of the grinding disc. During the grinding process, if the position of the grinding disc needs to be fine-tuned, it can be achieved by fine-tuning the adjusting screw. BRIEF DESCRIPTION OF THE DRAWINGS

The fixing plate 21 is fixed to the lower surface of the grinding disc body 1. The two connecting bolts 22 are respectively fixed to the left and right sides of the lower surface of the fixing plate 21. The connecting plate 23 is slidably connected to the outer sides of the two connecting bolts 22. The fixing plate 21 ensures the connection between the entire protection mechanism 2 and the grinding disc body 1. The fixing plate 21 is fixed to the grinding disc body 1 through the connecting bolts 22. It is connected to the connecting plate 23 and has a certain displacement when impacted, thereby absorbing and dispersing the impact force. The rubber pad 24 is mounted on the outside of the two connecting bolts 22 and is located between the fixing plate 21 and the connecting plate 23 on opposite sides. The rubber pad 24 is located between the fixing plate 21 and the connecting plate 23 to play a buffering role. The plug-in block 25 is fixed to the lower surface of the connecting plate 23, and the support frame 26 is slidably connected to the outside of the plug-in block 25. The buffer member 27 is arranged on the inner bottom wall of the support frame 26 to increase the elastic impact resistance effect. The lower surface of the support frame 26 is fixed with a mounting plate 28.

[0024] The buffer member 27 includes a plurality of support springs 271 fixed to the inner bottom wall of the support frame 26, and a top plate 272 is fixed to the upper surface of the plurality of support springs 271. The buffer member 27 is arranged on the inner bottom wall of the support frame 26 to increase the elasticity and impact resistance. The spring can provide a restoring force to help the system quickly return to its original state after being impacted.

[0025] In this embodiment, a plug interface is provided on the back side of the support frame 26, and the support frame 26 is slidably connected to the outer side of the plug-in block 25 through the plug interface. The cross-sectional shape of the plug-in block 25 is T-shaped, and the width of the top plate 272 is equal to the length of the plug-in block 25. The outer sides of the two connecting bolts 22 are threaded with locking nuts. The plug-in block 25 is used to enhance the stability of the connecting plate 23 and serves as the connection point of the support frame 26. The sliding connection of the support frame 26 allows a certain degree of displacement when impacted, thereby increasing the impact resistance of the entire protective mechanism 2.

[0026] See also Figure 3In order to adjust and support the grinding disc to prevent excessive deviation, the supporting mechanism 3 in this embodiment includes four adjusting screws 31, four threaded sleeves 32 and four soft pads 33. The four adjusting screws 31 are respectively fixed to the four corners of the upper surface of the mounting plate 28. According to the working requirements of the grinding disc, the adjusting screws 31 are positioned to a suitable position to determine the height and angle of the supporting point. The four threaded sleeves 32 are respectively threadedly connected to the outer sides of the four adjusting screws 31. By rotating the adjusting screws 31, the extension length thereof is adjusted to change the distance between the supporting mechanism 3 and the grinding disc body 1 to ensure that the grinding disc body 1 will not deviate excessively during the grinding process, thereby ensuring the grinding effect. The four soft pads 33 are respectively connected to the top ends of the four threaded sleeves 32. During the grinding process, if the grinding disc is subjected to impact or vibration, the soft pads 33 and the supporting springs 271 will absorb these impacts to reduce the impact on the grinding disc.

[0027] In this embodiment, the diameter of the soft pad block 33 is larger than the diameter of the threaded sleeve 32, and the length of the threaded sleeve 32 is equal to the length of the adjusting screw 31. The support spring 271 helps the supporting mechanism 3 to return to its original position after being impacted, thereby maintaining the stability of the grinding disc. During the grinding process, if the position of the grinding disc needs to be fine-tuned, it can be achieved by fine-tuning the adjusting screw 31.

[0028] The working principle of the above embodiment is:

[0029] (1) When the grinding disc is used to improve the impact resistance and protection effect, the fixing plate 21 ensures the connection between the entire protection mechanism 2 and the grinding disc body 1. The fixing plate 21 is connected to the connecting plate 23 by the connecting bolts 22. When impacted, there is a certain displacement, thereby absorbing and dispersing the impact force. The rubber pad 24 is located between the fixing plate 21 and the connecting plate 23 to play a buffering role. The plug-in block 25 is used to enhance the stability of the connecting plate 23 and serves as a connection point for the support frame 26. The sliding connection of the support frame 26 allows a certain degree of displacement when impacted, thereby increasing the impact resistance of the entire protection mechanism 2. The buffer 27 is arranged on the inner bottom wall of the support frame 26 to increase the elastic impact resistance effect. The spring can provide a restoring force to help the system quickly return to its original state after an impact.

[0030] (2) When adjusting the grinding wheel to support the grinding wheel to prevent excessive displacement, the adjusting screw 31 is positioned to a suitable position according to the working requirements of the grinding wheel to determine the height and angle of the support point. The adjusting screw 31 is rotated to adjust its extended length, thereby changing the distance between the supporting mechanism 3 and the grinding wheel body 1 to ensure that the grinding wheel body 1 will not be excessively displaced during the grinding process, thereby ensuring the grinding effect. During the grinding process, if the grinding wheel is impacted or vibrated, the soft pad block 33 and the supporting spring 271 will absorb these impacts to reduce the impact on the grinding wheel. The supporting spring 271 helps the supporting mechanism 3 to return to its original position after being impacted to maintain the stability of the grinding wheel. During the grinding process, if the position of the grinding wheel needs to be fine-tuned, this can be achieved by fine-tuning the adjusting screw 31.
