[0003] In the prior art, the outer wall of grinding wheels is mostly covered with a protective sleeve to prevent the grinding wheel from flying off when it is damaged. However, when such grinding wheels need to be disassembled, the outer protective sleeve often needs to be removed first before the grinding wheel can be disassembled. This process often requires multiple tools and consumes a lot of time and effort to complete the disassembly. Therefore, those skilled in the art provide a quick-release diamond grinding wheel tool to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to provide a quick-release diamond grinding wheel to solve the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a quick-release diamond grinding wheel, including a base and a grinding wheel. A dual-axis motor is fixedly connected to the center of the upper top of the base. Both output ends of the dual-axis motor are fixedly connected to drive shafts. The outer walls of the two drive shafts are slidably fitted with grinding wheels. A first quick-release mechanism and a second quick-release mechanism for disassembling the grinding wheel are provided on both sides of the outer wall of the dual-axis motor.

[0006] Preferably, each group of the first quick-release mechanism includes an inner cover, and a plurality of limiting arms are fixedly connected in a circular array on the side of the inner cover near the dual-axis motor. The end of the limiting arm away from the inner cover is fixedly connected to the outer side wall of the dual-axis motor.

[0007] Preferably, the inner wall of the inner cover is fixedly connected with a number of positioning sleeves in an annular array, the outer wall of the inner cover is fixedly connected with four buckles in an annular array, and the outer wall of the inner cover has three through slots with an L-shaped cross section.

[0008] Preferably, each group of the second quick-release mechanism includes an outer cover, and the outer side wall of the outer cover is fixedly connected with a plurality of buckles that cooperate with the buckle in a ring array. The buckle is engaged with the buckle. The outer side wall of the outer cover is fixedly connected with three fixed brackets in a ring array, and each fixed bracket is located between two buckles.

[0009] Preferably, each of the fixed brackets has a damped push arm connected to its inner sidewall. In the working state, the push arm is located inside the through groove and is used to push the grinding wheel to make linear motion. The inner sidewall of the outer cover is fixedly connected with several fixed frames in a circular array. Each fixed frame is fixedly connected with a positioning rod on the side near the inner cover. The positioning rod is sleeved inside the positioning sleeve.

[0010] Preferably, a protective cover is fixedly connected to the center of the side of the outer cover away from the inner cover, and an installation sleeve is fixedly connected to the center of the grinding wheel.

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0016] Please see Figure 1 - Figure 4 As shown, this utility model provides a technical solution: a quick-release diamond grinding wheel, including a base 1 and a grinding wheel 3. A dual-axis motor 2 is fixedly connected to the center of the top end of the base 1. Both output ends of the dual-axis motor 2 are fixedly connected to drive shafts 6. The outer walls of the two drive shafts 6 are slidably sleeved with the grinding wheel 3. A first quick-release mechanism 4 and a second quick-release mechanism 5 for disassembling the grinding wheel 3 are provided on both sides of the outer wall of the dual-axis motor 2.

[0017] It should be noted that the dual-axis motor 2 at the top center of the base 1 can simultaneously drive two drive shafts 6 to rotate, thereby driving two grinding wheels 3 to rotate, realizing synchronous operation of dual workstations. When the grinding wheel 3 is worn and needs to be replaced, there is no need to use complicated tools. Through the first quick-release mechanism 4 and the second quick-release mechanism 5, the operator can quickly remove the grinding wheel 3 from the drive shaft 6 in a short time. Similarly, a new grinding wheel 3 can be quickly installed, which greatly shortens the equipment downtime and improves production continuity.

[0018] As one implementation method in this embodiment, please refer to Figure 2 and Figure 3 As shown, each group of first quick-release mechanisms 4 includes an inner cover 41. Several limiting arms 42 are fixedly connected in a ring array on the side of the inner cover 41 near the dual-axis motor 2. The end of the limiting arm 42 away from the inner cover 41 is fixedly connected to the outer side wall of the dual-axis motor 2. Several positioning sleeves 43 are fixedly connected in a ring array on the inner side wall of the inner cover 41. Four buckles 45 are fixedly connected in a ring array on the outer side wall of the inner cover 41. Three through slots 44 with an L-shaped cross section are opened in the ring array on the outer side wall of the inner cover 41.

[0019] It should be noted that the inner cover 41 is securely connected to the outer wall of the dual-axis motor 2 through several limiting arms 42. Several positioning sleeves 43 in a ring array on the inner wall of the inner cover 41 can be accurately positioned when installing the grinding wheel 3. The four buckles 45 in a ring array on the outer wall of the inner cover 41 provide convenient leverage points for operators, making it easy to disassemble and assemble without the need for complicated tools, which can be easily completed by hand, greatly shortening the disassembly and assembly time.

[0020] As one implementation method in this embodiment, please refer to Figure 2 - Figure 4 As shown, each set of second quick-release mechanisms 5 includes an outer cover 51. The outer wall of the outer cover 51 is fixedly connected with a number of buckles 53 that cooperate with the buckle 45 in a ring array. The buckle 45 is engaged with the buckle 53. The outer wall of the outer cover 51 is fixedly connected with three fixed brackets 54 in a ring array. Each fixed bracket 54 is located between two buckles 53. The inner wall of each fixed bracket 54 is damped and connected with a push arm 55. In the working state, the push arm 55 is located inside the through groove 44. The push arm 55 is used to push the grinding wheel 3 to make linear motion. The inner wall of the outer cover 51 is fixedly connected with a number of fixed frames 56 in a ring array. Each fixed frame 56 is fixedly connected with a positioning rod 57 on the side near the inner cover 41. The positioning rod 57 is sleeved inside the positioning sleeve 43.

[0021] It should be noted that several buckles 53 on the outer side wall of the outer cover 51 are engaged with the buckle 45 of the first quick-release mechanism 4, which is simple to operate and can quickly achieve the initial fixation of the outer cover 51 and the inner cover 41, saving assembly time. Three fixed brackets 54 are arranged in a ring on the outer side wall of the outer cover 51, and each is located between two buckles 53. The push arm 55 connected by the damping on its inner side wall can be located inside the through groove 44 in the working state. When it is necessary to remove the grinding wheel 3, pushing the push arm 55 can directly push the grinding wheel 3 to make linear motion, so that it can quickly detach from the drive shaft 6 without complicated operation, greatly improving the disassembly efficiency. Several fixed brackets 56 on the inner side wall of the outer cover 51 have positioning rods 57 on the side near the inner cover 41 that are sleeved inside the positioning sleeve 43, which further enhances the accuracy and stability of the connection between the outer cover 51 and the inner cover 41, ensuring that the position of each component is accurate during the disassembly and assembly process.

[0022] As one implementation method in this embodiment, please refer to Figure 2 - Figure 4As shown, a protective cover 52 is fixedly connected to the center of the outer cover 51 on the side away from the inner cover 41. An installation sleeve 31 is fixedly connected to the center of the grinding wheel 3. Positioning grooves 32 are opened on both ends of the outer wall of the installation sleeve 31. The installation sleeve 31 is slidably sleeved with the drive shaft 6. The grinding wheel 3 is slidably sleeved with the drive shaft 6 through the installation sleeve 31. Inner bearings 46 are fixedly connected to the center of the outer walls of the inner cover 41 and the outer cover 51. Limiting top brackets 47 are fixedly connected to the side of the two inner bearings 46 that are close to each other. The two limiting top brackets 47 are rotatably sleeved inside the two positioning grooves 32.

[0023] It should be noted that the mounting sleeve 31 at the center of the grinding wheel 3 is slidably sleeved with the drive shaft 6, facilitating the quick installation and removal of the grinding wheel 3 on the drive shaft 6. The positioning grooves 32 at both ends of the outer wall of the mounting sleeve 31 are rotatably sleeved with the limiting top bracket 47 connected to the inner bearing 46 at the center of the outer wall of the inner cover 41 and the outer cover 51. When the grinding wheel 3 rotates, the limiting top bracket 47 rotates within the positioning groove 32, which can accurately limit the axial movement of the grinding wheel 3, preventing axial movement of the grinding wheel 3 during high-speed rotation and ensuring the smooth operation of the grinding wheel 3. Furthermore, the outer cover 51 and the inner cover 41 are connected to the drive shaft 6 via the inner bearing 46. Shaft 6 is slidably sleeved, and during the rotation of drive shaft 6, outer cover 51 and inner cover 41 do not rotate. Since outer cover 51 is sleeved inside positioning sleeve 43 through positioning rod 57, when buckle 45 and buckle 53 cooperate, they can limit the outer cover 51. Inner bearing 46 is divided into outer ring and inner ring, and there are balls between the outer ring and inner ring. Therefore, the inner ring will rotate under the rotation of drive shaft 6, while the outer ring will not rotate under the action of the balls. When mounting sleeve 31 rotates, limiting top bracket 47 will rotate and sleeve inside positioning groove 32, thereby limiting the position of grinding wheel 3.

[0024] Working principle: When it is necessary to disassemble the grinding wheel 3, the inner cover 41 of the first quick-release mechanism 4 and the outer cover 51 of the second quick-release mechanism 5 are limited by the engagement of four buckles 45 on the outer wall of the inner cover 41 and several snaps 53 on the outer wall of the outer cover 51. Therefore, the buckles 45 and snaps 53 are released first. Then, the push arm 55 connected to the inner wall of the three fixed brackets 54 on the outer wall of the outer cover 51 is rotated so that the push arm 55 is located inside the three L-shaped through slots 44 opened in the annular array on the outer wall of the inner cover 41. At this time, the end of the push arm 55 is on the side of the grinding wheel 3. When the outer cover 51 is moved, the three push arms 55 will pull the grinding wheel 3 to move in a straight line. The grinding wheel 3 moves in a straight line on the outer wall of the drive shaft 6 through the mounting sleeve 31, which is fixed at the center and slidably connected to the drive shaft 6. This facilitates disassembly and cleaning of debris inside the mounting sleeve 31 and the outer cover 51. When installing the grinding wheel 3, the inner bearing 46 at the center of the outer wall of the inner cover 41 and the outer cover 51 has its inner ring fixed to the limiting top bracket 47. After the outer cover 51 and the inner cover 41 are installed, the two limiting top brackets 47 are engaged in the positioning grooves 32 at both ends of the outer wall of the mounting sleeve 31 to axially limit the position of the grinding wheel 3. This method enables quick disassembly and assembly of the grinding wheel 3.

[0025] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
