Abstract
Description
Technical Field
[0001] This invention belongs to the technical field of quartz grinding equipment, specifically relating to a quartz grinding rotary cutting device. Background Technology
[0002] High-purity quartz grinding wheels are an important basic raw material for manufacturing various quartz glass products in the shapes of tubes, rods, and plates. Quartz material has the characteristics of high temperature resistance, hard structure, and excellent corrosion resistance. However, the transitional shape of the coarse and fine ends of the quartz grinding wheel in its normal state places high demands on the grinding equipment. In addition, a uniformly thick contamination layer adheres to the surface of the quartz grinding wheel. Due to its shape, it is necessary to avoid grinding the uniformity of the thickness when grinding the surface layer. Based on this, our company has designed a quartz grinding wheel rotary cutting device that makes quartz grinding wheels with different heights at the coarse and fine ends as parallel as possible, and uses the weight of the electric grinder to grind the quartz grinding wheel in close contact with it, to replace the existing technology. Utility Model Content
[0003] Purpose of the invention: The purpose of this invention is to provide a quartz grinding wheel cutting device to solve the technical problem of grinding difficulties caused by the different heights of the two far-away ends of the quartz wheel.
[0004] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a quartz grinding wheel rotary cutting device for grinding quartz grinding wheels, characterized in that the rotary cutting device includes a frame and a support wheel assembly, the support wheel assembly mounted on the frame for supporting the quartz grinding wheel and driving the quartz grinding wheel to roll, and an adjusting top wheel mounted on the frame for restricting the rotation of the quartz grinding wheel on the support wheel assembly, and a grinding device mounted on the frame and reciprocating along the axial direction of the quartz grinding wheel, wherein the grinding device utilizes its own weight to contact and grind the surface of the quartz grinding wheel during the movement of the grinding device.
[0005] Furthermore, the support wheel assembly is a flexible elastic wheel assembly.
[0006] Furthermore, the flexible elastic wheel assembly is a sealed body made of rubber and textile materials. By inflating the flexible elastic wheel assembly, a buffering effect is achieved during the rotation of the irregular shape of the quartz weight.
[0007] Furthermore, the flexible elastic wheel assembly includes at least two elastic wheels.
[0008] Furthermore, to ensure the stability of the contact between the grinding device and the quartz stone, the grinding device uses one or more of the following combinations to make the grinding device contact the surface of the quartz stone: its own weight, counterweight, cylinder, hydraulic cylinder, electric cylinder, pressure boosting or pressure reducing device.
[0009] Furthermore, the grinding device maintains an angle of 1-45° with the axial direction of the quartz grinding wheel.
[0010] Compared with the prior art, the present invention has the following advantages: by using a support wheel set in combination with a support top wheel, when the shape of the quartz weight is transitional, the larger weight on the thicker side exerts a larger force on the flexible wheel. After the flexible wheel is subjected to force, it contracts to make the quartz weight as flat as possible, which has good applicability and scalability. Attached Figure Description

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
[0018] In the description of the invention, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0019] In the first embodiment of the present invention, as Figure 1-6 As shown, a quartz grinding wheel rotary cutting device is used for grinding quartz grinding wheels. The rotary cutting device includes a frame 1 and a support wheel assembly. The support wheel assembly installed on the frame 1 is used to support the quartz grinding wheel and drive the quartz grinding wheel to roll. An adjusting top wheel installed on the frame restricts the rotation of the quartz grinding wheel on the support wheel assembly. A grinding device is installed on the frame and reciprocates along the axial direction of the quartz grinding wheel. During the movement of the grinding device, it uses its own weight to contact and grind the surface of the quartz grinding wheel.
[0020] Specifically, the frame includes a main frame and a sub-frame, which can be either integrated or spaced apart. A set of support wheels is installed on the frame 1. The support wheels are used to place the quartz weight. The support wheels are flexible and elastic. An adjusting top wheel is used to position the quartz weight so that the quartz weight rotates between the support wheels. The grinding device reciprocates along the placement direction of the quartz weight. The grinding device uses its own weight to contact the quartz weight, thereby grinding different positions of the quartz weight.
[0021] like Figure 1 and Figure 2 As shown, the support wheel assembly is installed on the main frame and two sets of support wheel assemblies are arranged in parallel. The quartz weight is placed between the two sets of support wheel assemblies. The support wheel assembly includes a bearing seat 2 installed on the bracket 1 and a rotating shaft 3 limited by the bearing seat 2. The rotating shaft 3 rotates between the bearing seats 2. Multiple flexible wheels 4 are installed on the rotating shaft 3. The rotating shaft 3 is driven to rotate by an external power source. The external power source can be one of motor drive, belt pulley drive, or sprocket drive. There are two or more flexible wheels 4, preferably four flexible wheels. The flexible wheels 4 are not evenly spaced on the rotating shaft 3 to match quartz weights of different specifications. The flexible wheel 4 on the coarse side of the quartz weight is fixed to the rotating shaft.
[0022] The flexible wheel 4 is a sealed body made of rubber and textile materials. By inflating the flexible wheel 4, the transition shape of the quartz weight from fine to coarse is achieved. One option is to connect an air tube to each flexible wheel 4, so that gas can be injected into or released from the flexible wheel 4 through the air tube. In order to ensure that the two ends of the quartz weight are as parallel as possible after it is placed, the heavier end of the quartz weight exerts a greater force on the flexible wheel 4, causing the flexible wheel 4 to contract and descend, so that the two ends of the quartz weight are as parallel as possible.
[0023] like Figure 3 As shown, the adjusting top wheel includes two upright plates 12 installed on both sides of the frame 1. The upright plates 12 are two pieces respectively installed at the two ends of the main frame that are far apart from each other. The rotating rod 13 is a threaded rod with a threaded hole in the upright plate 12. The rotating rod 13 is threaded through the upright plate 12. The fitting piece 14 is fixedly connected to the rotating rod 13. The fitting piece 14 is a cage with a plane that gradually shrinks. The two supporting top wheels support the quartz weight in opposite directions. The two fitting pieces 14 are opposite to each other, so that the flat end of the cage fits with the end face of the quartz weight.
[0024] like Figure 1 and Figure 2As shown, the grinding device includes a lead screw 5 mounted on the frame and a screw sleeve platform 10 that moves with the lead screw 5. A grinding machine 11 is mounted on the screw sleeve platform 10. The end of the lead screw 5 is mounted on the frame 1 via a bearing. One end of the lead screw 5 is fixedly connected to a first sprocket 6. The output end of the motor 7 is connected to a second sprocket 8 and then the first sprocket 6 and the second sprocket 8 are connected via a chain 9. It should be noted that the lead screw 5 is mounted on a secondary frame and drives the second sprocket 8 via the motor 7. The second sprocket 8 drives the first sprocket 6 via the chain 9. During the rotation of the first sprocket 6, the lead screw 5 rotates, causing the screw sleeve platform 10 to move, thereby allowing the grinding machine 11 to grind different positions of the quartz stone. The grinding arm of the grinding machine 11 has a preset rotation gap of 15 to 45 degrees, thereby matching and grinding the transitional quartz stone. During the grinding process, the grinding wheel of the grinding machine 11 is in close contact with the surface of the quartz stone.
[0025] like Figures 4-6 As shown, the grinding mechanism 11 includes a set of mounting plates 15 that are inclinedly mounted on the screw sleeve table 10. There are two mounting plates 15. A swing arm 17 is mounted on the adjusting shaft 16 located between the mounting plates 15. The adjusting shaft 16 located outside the mounting plates 15 is fixedly connected to the swing plate 18.
[0026] The first drive motor 19 is fixedly connected to the rotating disk 20. Four screws 21 are arranged at equal intervals on the rotating disk 20. The swing plate 18 is located between the screws 21. There is a gap between the bolts 21 and the swing plate 18, so that the swing arm 17 can swing freely within a certain range. It should be noted that its maximum swing amplitude is less than 45°. During the movement of the screw sleeve table 10, the swing arm and the grinding wheel can swing with the transition shape change of the quartz weight.
[0027] When the required adjustment range is greater than the free clearance, the first drive motor 19 rotates to drive the rotating disk 20. During the rotation of the rotating disk 20, it gradually approaches the swing plate 18 until it is in contact with the swing plate 18 and continues to move to realize the swing of the swing arm.
[0028] The swing arm 17 is also equipped with a drive wheel 23 driven by a second drive motor 22, and a driven wheel 25 connected to the drive wheel 23 by a belt 24. The driven wheel 25 is connected to the grinding wheel 26, thereby driving the grinding wheel 26 to rotate.
[0029] It should also be noted that the grinding mechanism is installed at an angle, thereby creating an angle between the grinding wheel and the surface of the quartz grinding wheel.
[0030] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements can be made without departing from the principle of the present invention, and these improvements should also be considered within the scope of protection of the present invention.
