Description

Technical Field

[0001] The invention relates to the technical field of edge grinding machines, in particular to a glass edge grinding machine with controllable grinding force. Background Art

[0002] Glass edge grinding machine is one of the earliest and most widely used mechanical equipment in glass deep processing equipment. Its main function is to grind glass and make some special shapes. The correct and reasonable use of edge grinding machine can not only ensure the normal production, but also extend the life of the machine. It is divided into single-arm special-shaped edge grinding machine, linear edge grinding machine and template edge grinding machine. The existing glass edge grinding machine cannot push the glass tightly. When people use the glass edge grinding machine, they cannot grind the glass of different widths and cannot adjust the width of different glass conveying. It is easy to cause the glass to loosen and deviate, resulting in uneven edge grinding and affecting the edge grinding quality.

[0003] To this end, a Chinese patent with publication number "CN219094615U" has published a "single-sided glass edge grinding machine", the main structure of which includes a workbench, a first concave seat is fixedly connected to the right side of the top of the workbench, a cylinder is fixedly connected to the left side of the inner cavity of the workbench, a push rod is fixedly connected to the right side of the cylinder, a moving block is fixedly connected to the right side of the push rod, a moving column is fixedly connected to the top of the moving block, and the top of the moving column penetrates the top of the workbench and is fixedly connected to the second concave seat. In this single-sided glass edge grinding machine, when adjusting the conveying position, the cylinder drives the push rod to start moving, the push rod drives the moving block to start moving, the moving block drives the sliding sleeve to slide on the sliding rod, and at the same time the moving block drives the moving column to start moving, and the moving column drives the second concave seat to start moving, so that the second concave seat moves to the specified position, and at this time the baffle presses the glass on the guide wheel tightly.

[0004] However, when the above-mentioned single-sided glass edge grinding is in operation, the grinding head and the glass surface are in hard contact, which will result in the two being able to provide only hard-contact grinding pressure during grinding, and the grinding pressure between the high-speed rotating grinding head and the glass surface cannot be controlled. Once the two are in contact in a high-speed motion, the entire piece of glass will be scrapped, which will easily lead to a decrease in the yield. Summary of the invention

[0005] In view of the shortcomings of the prior art, the present invention provides a glass edge grinding machine with controllable grinding force, which utilizes a coil spring to provide the torque resistance control effect required for linkage, and the intermediate medium is a buffer liquid.

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] See also Figure 1 and Figure 2 A glass edge grinding machine with controllable grinding force includes a driving motor 1 with a motor connecting plate 2 installed on the outer circumference and a grinding head 3 that rotates indirectly with the rotor 4 of the driving motor 1. The motor connecting plate 2 is fixedly installed on the corresponding part of the robot arm used to run according to a predetermined track.

[0028] To achieve the reserve effect on the buffer liquid, please refer to Figure 1 , Figure 2 and Figure 3, it is necessary to set up a middle liquid injection mechanism 5, which is provided with a middle hollow cylinder 51 which can indirectly rotate with the rotor 4 and is in a hollow state inside, and a liquid injection channel 57 which can fill the middle hollow cylinder 51 with buffer liquid. First, using the liquid injection equipment, the buffer liquid is filled into the liquid reserved cavity 54 and each sealed space connected to the liquid reserved cavity 54 through the liquid valve 58 until the buffer liquid is discharged outward through the No. 5 liquid flow hole 76, and the injection of the liquid can be stopped, thereby achieving the reservation effect of the buffer liquid.

[0029] For the specific structure of the middle liquid injection mechanism 5, please refer to Figure 3 , including a middle hollow cylinder 51, the bottom and top of the middle hollow cylinder 51 are respectively provided with a first connecting plate 52 and a second connecting plate 53, the interior of the middle hollow cylinder 51 is provided with a liquid reserved cavity 54, the bottom of the middle hollow cylinder 51 is provided with a first liquid flow hole 55 connecting the external space and the bottom of the liquid reserved cavity 54, the top of the middle hollow cylinder 51 is provided with a second liquid flow hole 56 connecting the external space and the top of the liquid reserved cavity 54, the circumferential side of the middle hollow cylinder 51 is provided with a liquid injection channel 57 connecting the external space and the liquid reserved cavity 54, and a liquid valve 58 is installed inside. The liquid valve 58 is a valve that can control the outward flow of liquid and enable the buffer liquid to be normally injected into the liquid reserved cavity 54.

[0030] To achieve a separable linkage effect, see Figure 1 , Figure 2 , Figure 4 and Figure 5, it is necessary to set up a separate combined linkage mechanism 6, which is provided with a bottom hollow cylinder 61 fixedly installed at the bottom of the middle hollow cylinder 51 and connected to the internal structure of the middle hollow cylinder 51, a piston plate 67 arranged inside the bottom hollow cylinder 61 and capable of moving downward under the action of the buffer liquid pressure, an upper rotating disk 69 located inside the bottom hollow cylinder 61 and capable of longitudinally moving with the piston plate 67, a lower rotating disk 611 located directly below the upper rotating disk 69, and three lower rotating disks 611 arranged in a circular array on the upper rotating disk 69 The ball 614 is disposed between the lower rotating disk 611 and the lower rotating disk 611, and can make the lower rotating disk 611 rotate with the upper rotating disk 69. Under normal working conditions, the middle hollow cylinder 51 will drive the bottom hollow cylinder 61 to rotate. Since the structural shape of the cross section of the rod body through hole 65 is consistent with the structural shape of the cross section of the central linkage shaft 68, both of which are polygonal structures, and the structural size of the cross section of the rod body through hole 65 matches the structural size of the cross section of the central linkage shaft 68, the bottom hollow cylinder 61 will drive the central linkage shaft 68 and the upper rotating disk 69 to rotate. The movable plate 69 rotates. At the same time, under the pressure of the buffer liquid, the piston plate 67 will make the upper rotating plate 69 and the lower rotating plate 611 have a mutual squeezing force, which will prevent the ball 614 from leaving the upper hemispherical groove 612, thereby driving the lower rotating plate 611 to rotate, and finally driving the bottom rotating shaft 610 and the grinding head 3 to rotate. The moving stroke of the grinding head 3 is controlled by the mechanical arm, so as to grind the glass. Once the friction resistance between the grinding head 3 and the glass surface during the grinding process, that is, the grinding pressure is greater than When the elastic strength of the coil spring 78 is increased, the coil spring 78 will be compressed, and the buffer liquid will be discharged outward through the No. 5 liquid flow hole 76. At this time, the pressure of the liquid on the piston body 67 is insufficient, and the force of mutual extrusion between the upper rotating disk 69 and the lower rotating disk 611 will be reduced until the ball 614 is separated from the upper hemispherical groove 612. At this time, the bottom hollow cylinder 61 rotates normally under the action of the driving motor 1, and the lower rotating disk 611 cannot drive the grinding head 3 to continue rotating, thereby realizing a detachable linkage effect.

[0031] For the specific structure of the separation combined linkage mechanism 6, please refer to Figure 4 and Figure 5, including a bottom hollow cylinder 61, the top of the bottom hollow cylinder 61 is provided with a No. 3 connecting plate 62 which is an integral structure with it and fixedly mounted on the bottom of the No. 1 connecting plate 52, the interior of the bottom hollow cylinder 61 is provided with a No. 1 component active cavity 63, the top of the No. 1 component active cavity 63 is provided with a No. 3 liquid flow hole 64, the top of the No. 3 liquid flow hole 64 is connected to the bottom of the No. 1 liquid flow hole 55, the bottom center of the No. 1 component active cavity 63 is provided with a rod body through hole 65, the bottom end of the rod body through hole 65 A movable chamber 615 of component No. 2 is provided, and a component mounting hole 66 communicating with the external space is provided at the bottom end of the movable chamber 615 of component No. 2; a piston plate 67 capable of axially moving along the movable chamber 63 of component No. 1 is arranged inside the movable chamber 63 of component No. 1; a central linkage shaft 68 penetrating the through hole 65 of the rod body is fixedly installed at the bottom end of the piston plate 67; an upper rotating disk 69 is fixedly installed at one end of the central linkage shaft 68 located inside the movable chamber 615 of component No. 2; the bottom hollow cylinder 61 is provided with a piston plate 67 capable of axially moving along the movable chamber 63 of component No. 1; a central linkage shaft 68 penetrating the through hole 65 of the rod body is fixedly installed at the bottom end of the piston plate 67; and an upper rotating disk 69 is fixedly installed at one end of the central linkage shaft 68 located inside the movable chamber 615 of component No. 2. A rotatable bottom rotating shaft 610 is installed inside the component mounting hole 66 through a bearing, and the bottom end of the bottom rotating shaft 610 is fixedly connected to the grinding head 3, and the top of the bottom rotating shaft 610 is fixedly installed with a lower rotating disk 611 inside the movable cavity 615 of the second component, and the bottom of the upper rotating disk 69 and the top of the lower rotating disk 611 are respectively provided with three upper and lower corresponding upper hemispherical grooves 612 and lower hemispherical grooves 613, and each corresponding upper hemispherical groove 612 and lower hemispherical groove 613 are respectively provided with a lower hemispherical groove 613. 3, a ball 614 is placed between the upper and lower hemispherical grooves 612 and 613, the structural radius of the upper hemispherical groove 612 and the lower hemispherical groove 613 matches the structural radius of the ball 614, and the depth of the upper and lower hemispherical grooves 612 and 613 is smaller than the structural radius of the ball 614, and the lateral distance between the center of the ball 614 and the bottom of the upper rotating disk 69 and the longitudinal axis of the lower rotating disk 611 is greater than the structural radius of the bottom of the upper rotating disk 69 and the lower rotating disk 611, and smaller than the structural diameter of the bottom of the upper rotating disk 69 and the lower rotating disk 611.

[0032] In order to achieve the maximum torque strength control of the equipment during operation, please refer to Figure 1 , Figure 2 , Figure 6 and Figure 7, it is necessary to set up a torque resistance control mechanism 7, which is provided with a top hollow cylinder 71 fixedly installed on the top of the middle hollow cylinder 51 and connected to the internal structure of the middle hollow cylinder 51, a resistance baffle 77 placed inside the top hollow cylinder 71 and capable of controlling the tendency of the buffer liquid to discharge outward, and a coil spring 78 capable of producing an elastic damping effect on the movement of the resistance baffle 77. Once the friction resistance between the grinding head 3 and the glass surface during the grinding process, that is, the grinding pressure, is greater than the elastic strength of the coil spring 78, the ball 614 will cause the upper rotating disk 69 and the lower rotating disk 611 to have a tendency to move away from each other, and Due to the connection relationship of the bearing, the lower rotating disk 611 will not move longitudinally, while the upper rotating disk 69 will tend to move upward, which will then compress the coil spring 78, and the buffer liquid will flow upward through the No. 4 liquid flow hole 75 and the gap between the plate body and the baffle 77, and will finally be discharged outward through the No. 5 liquid flow hole 76. At this time, the liquid has insufficient pressure on the piston body 67 until the ball 614 is separated from the upper hemispherical groove 612. At this time, the bottom hollow cylinder 61 rotates normally under the action of the drive motor 1, and the lower rotating disk 611 cannot drive the grinding head 3 to continue rotating, thereby achieving a detachable linkage effect.

[0033] For the specific structure of the torque resistance control mechanism 7, please refer to Figure 6 and Figure 7 , including a top hollow cylinder 71, a No. 4 connecting plate 73 fixedly connected to the top of the No. 2 connecting plate 53 is disposed at the bottom end of the top hollow cylinder 71, a shaft mounting groove 72 for fixing and mounting the rotor 4 is disposed at the top center of the top hollow cylinder 71, a No. 4 liquid flow hole 75 connected to the No. 2 liquid flow hole 56 is disposed at the bottom end of the top hollow cylinder 71, a No. 3 component active cavity 74 located at the top of the No. 4 liquid flow hole 75 is disposed inside the top hollow cylinder 71, a plurality of No. 5 liquid flow holes 76 connected to the external space and the No. 3 component active cavity 74 are disposed at the top of the top hollow cylinder 71, and a liquid flow hole capable of The baffle plate 77 moves axially along the movable cavity 74 of the third component, and the outer circumferential surface of the baffle plate 77 is provided with a plurality of concave structures and liquid flow grooves 79 for liquid flow, and the top of the baffle plate 77 is fixedly installed with a coil spring 78 in a compressed state, and the bottom end of the baffle plate 77 is embedded with an annular sealing ring 710, and the bottom surface of the annular sealing ring 710 protrudes downward relative to the bottom surface of the baffle plate 77, and the structural radius of the inner ring of the annular sealing ring 710 is greater than the structural radius of the fourth liquid flow hole 75, and the structural radius of the outer ring of the annular sealing ring 710 is smaller than the distance between the liquid flow groove 79 and the axial center line of the baffle plate 77.

[0034] When in use, the liquid injection device is used to fill the liquid reserved cavity 54 and each sealed space connected to the liquid reserved cavity 54 through the liquid valve 58 until the buffer liquid is discharged outward through the No. 5 liquid flow hole 76, and the injection of liquid can be stopped. The middle hollow cylinder 51 will drive the bottom hollow cylinder 61 to rotate, and since the structural shape of the cross section of the rod body through hole 65 is consistent with the structural shape of the cross section of the central linkage shaft 68, both are polygonal structures, and the structural size of the cross section of the rod body through hole 65 is consistent with the structural shape of the cross section of the central linkage shaft 68, The structural dimensions of the cross section of the linkage shaft 68 match, and the bottom hollow cylinder 61 will drive the central linkage shaft 68 and the upper rotating disk 69 to rotate. At the same time, under the pressure of the buffer liquid, the piston plate 67 will create a mutual squeezing force between the upper rotating disk 69 and the lower rotating disk 611, and this force will prevent the ball 614 from leaving the upper hemispherical groove 612, thereby driving the lower rotating disk 611 to rotate, and finally driving the bottom rotating shaft 610 and the grinding head 3 to rotate, and the moving stroke of the grinding head 3 is controlled by the robotic arm to grind the glass.
