Description

Technical Field

[0001] The present application relates to the technical field of glass frame cutting, and more specifically, to a glass frame cutting device. Background Art

[0002] Glass is an amorphous, inorganic, non-metallic material, typically made from a variety of inorganic minerals, with a small amount of auxiliary materials added. During the production of glass products, it often requires a frame to facilitate installation. During this process, the frame often requires cutting.

[0003] However, some existing cutting devices for glass frames have certain limitations. Specifically, they cannot simultaneously remove burrs generated at the cut during the frame cutting process, and usually require additional grinding equipment to grind the cut, which needs further improvement. Utility Model Content

[0004] In order to solve the above problems, the present application provides a glass frame cutting device.

[0005] The glass frame cutting device provided in this application adopts the following technical solution:

[0006] A glass frame cutting device includes a cutting body, an auxiliary handle is installed on the cutting body, and a connecting shaft is fixed to the output end of the cutting body through a coupling, a cutting blade and two grinding discs are sleeved on the connecting shaft, the cutting blade is located between the two grinding discs, and a group of reserved holes are opened on the cutting blade and the two grinding discs, and the reserved holes are used to pass screws, and a group of receiving grooves are opened on the side of the two grinding discs close to the cutting blade, the inner side of the receiving groove is fixedly connected to the compression spring, and a grinding block is movably provided on the inner side of the receiving groove, and the grinding block extends to the outside of the grinding disc away from the end of the compression spring.

[0007] Furthermore, the connecting shaft includes a connecting shaft body and a positioning plate, the positioning plate is mounted on the connecting shaft body, and the positioning plate and the connecting shaft body are integrally formed, the cutting disc and the two grinding discs are also mounted on the connecting shaft body, and the positioning plate is provided with a group of threaded holes that coincide with the reserved holes.

[0008] Furthermore, an end of the grinding block away from the compression spring is provided with an arc portion and a straight portion, and an end of the grinding block close to the compression spring extends toward the inner walls on both sides of the receiving groove.

[0009] Furthermore, the number of the reserved holes is not less than three, and the reserved holes are evenly distributed with the central axis of the connecting shaft as the center.

[0010] Furthermore, a protective cover is fixedly installed on one side of the cutting body close to the cutting blade, and the protective cover covers the upper half of the cutting blade.

[0011] Furthermore, the diameter of the positioning disc is smaller than the diameter of the grinding disc.

[0012] In summary, this application includes at least one of the following beneficial technical effects:

[0013] (1) When a cutting device is used to horizontally cut a glass frame, the output end of the cutting body drives the connecting shaft to rotate, thereby driving the cutting blade and the two grinding discs to rotate as a whole. The rotating cutting blade cuts the frame horizontally. As the horizontal cutting proceeds, the grinding blocks on the two grinding discs grind the cuts on both sides of the frame respectively, thereby removing burrs;

[0014] (2) The end of the grinding block away from the compression spring is provided with an arc portion and a straight portion. When the grinding block rotates and grinds the glass frame, the arc portion first contacts the cut of the frame, and plays the role of striking and smoothing the burrs on the cut. Then the chamfer of the straight portion can scrape off the burrs. The arc portion can also play a certain force guiding role, and cooperates with the compression spring to reduce the risk of scratching and damaging the glass frame.

[0015] (3) Since the receiving slot is provided on the side of the grinding disc close to the cutting blade, when the grinding block is damaged after long-term use, the grinding disc can be removed from the connecting shaft and the damaged grinding block in the receiving slot can be directly replaced.

Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0023] The following is combined with Figure 1-3 This application is described in further detail.

[0024] The embodiment of the present application discloses a glass frame cutting device, including a cutting body 1, see Figure 1 It can be understood that in order to enhance the stability of the cutting device during the cutting process, an auxiliary handle 2 is installed on the cutting body 1, and the user can hold the cutting body 1 and the auxiliary handle 2 with both hands respectively. It should be noted that the output end of the cutting body 1 is fixed with a connecting shaft 4 through a coupling, and a cutting blade 8 and two grinding discs 5 are sleeved on the connecting shaft 4. The cutting blade 8 is located between the two grinding discs 5, and the cutting blade 8 and the two grinding discs 5 are tightly attached. When the cutting body 1 is powered on, the cutting blade 8 and the two grinding discs 5 rotate as a whole following the connecting shaft 4; combined with Figure 3 As shown, it should be further explained that a group of receiving grooves 9 are opened on the side of the two grinding discs 5 close to the cutting blade 8. The receiving grooves 9 are evenly distributed with the central axis of the grinding disc 5 as the center of the circle, and the narrow notch of the receiving groove 9 extends to the outer edge of the grinding disc 5. Please refer to Figure 3A compression spring 10 is fixedly connected to the inner side of the storage groove 9, and a grinding block 6 is movably provided on the inner side of the storage groove 9. The compression spring 10 is against the grinding block 6. The end of the grinding block 6 away from the compression spring 10 passes through the narrow slot and extends to the outside of the grinding disk 5. When the grinding disk 5 rotates, the grinding block 6 rotates with the grinding disk 5. During this process, the rotating grinding block 6 can be used to grind the cut of the glass frame, so that the cut of the frame is smooth and free of burrs.

[0025] Please combine Figure 1 、 Figure 2 and Figure 3 As shown, it should be noted that in order to be able to fix the cutting blade 8 and the grinding disc 5 as a whole on the connecting shaft 4, a group of reserved holes 7 are opened on the cutting blade 8 and the two grinding discs 5. The reserved holes 7 are used to penetrate screws. It can be understood that the number of reserved holes 7 is not less than three, and the reserved holes 7 are evenly distributed with the central axis of the connecting shaft 4 as the center of the circle to ensure the firmness and stability of the cutting blade 8 and the grinding disc 5 when rotating; It should be further noted that the connecting shaft 4 includes a connecting shaft body 41 and a positioning plate 42, and the positioning plate 42 is sleeved on the connecting shaft body 41. On the connecting shaft body 41, the positioning disk 42 is integrally formed with the connecting shaft body 41. It can be understood that the diameter of the positioning disk 42 is smaller than the diameter of the grinding disk 5 to avoid obstruction to the grinding of the grinding disk 5. The connecting shaft body 41 and the output end of the cutting body 1 are fixed by a coupling, and the cutting blade 8 and the two grinding disks 5 are also sleeved on the connecting shaft body 41. A group of threaded holes 43 coinciding with the reserved holes 7 are opened on the positioning disk 42. By passing the screws through the reserved holes 7 and tightening them in the threaded holes 43, the cutting blade 8 and the grinding disk 5 can be fixed to the connecting shaft 4.

[0026] See also Figure 1 and Figure 3 It should be noted that the end of the grinding block 6 away from the compression spring 10 is provided with an arc-shaped portion and a straight portion. When the grinding block 6 rotates to grind the glass frame, the arc-shaped portion first contacts the cut of the frame, and plays a role in striking and smoothing the burrs at the cut. Then the chamfer of the straight portion can scrape off the burrs, and the arc-shaped portion can play a certain force guiding role, cooperating with the compression spring 10 to reduce the risk of scratching and damaging the glass frame; it should be further noted that the end of the grinding block 6 close to the compression spring 10 extends toward the inner walls of both sides of the receiving groove 9, so as to prevent the grinding block 6 from falling off from the receiving groove 9. A protective cover 3 is fixedly installed on the side of the cutting body 1 close to the cutting blade 8. The protective cover 3 covers the upper half of the cutting blade 8 to prevent debris from flying upward during cutting.

[0027] The implementation principle of a glass frame cutting device in an embodiment of the present application is as follows: when the cutting device is used to perform horizontal cutting on the surface of the glass frame, the output end of the cutting body 1 drives the connecting shaft 4 to rotate, thereby driving the cutting blade 8 and the two grinding discs 5 to rotate as a whole, and the rotating cutting blade 8 performs horizontal cutting on the frame. As the horizontal cutting proceeds, the grinding blocks 6 on the two grinding discs 5 grind the cuts on both sides of the frame respectively, thereby removing burrs. During this process, the grinding blocks 6 are retracted into the storage slots due to the reaction force of the frame. 9, so as to avoid excessive grinding of the frame. When the grinding block 6 is out of contact with the frame, the grinding block 6 will gradually reset due to the centrifugal force during rotation and the elastic force of the compression spring 10. Of course, if the frame needs to be completely cut off, the grinding block 6 needs to be used again to grind the incision at the bottom of the frame. Since the receiving groove 9 is opened on the side of the grinding disc 5 close to the cutting blade 8, when the grinding block 6 is damaged after long-term use, the grinding disc 5 can be removed from the connecting shaft 4, and the damaged grinding block 6 in the receiving groove 9 can be directly replaced.

[0028] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
