Description

Technical Field

[0001] This utility model relates to the field of grinding machine spindle scraping technology, specifically to a scraping spindle drive device. Background Technology

[0002] Centerless grinders are a type of grinder that does not require workpiece axis positioning for grinding. The rotation of the grinding wheel and the adjusting wheel relies on the precise fit between the spindle and the bearing. In order to ensure that the machining accuracy meets the requirements and the contact clearance between the spindle and the bearing is met, the bearing usually needs to be scraped. For example, as recorded in the literature Wang Tongsheng. CNC machine tool spindle accuracy adjustment and maintenance method [J]. Modern Vocational Education, 2017, (29):117, scraping repair method can be effectively used to better solve the problems existing in the actual machining of CNC lathe spindles.

[0003] When scraping the bearing bush, a colorant is applied to the surface of the spindle, and then the spindle is placed on the bearing bush for grinding. The spindle is rotated to find the high point on the inner wall of the bearing bush. Currently, when grinding the spindle and the bearing bush, it is necessary to manually hold the spindle with a rotating handle and rotate it manually. This not only increases the workload, but also causes uneven force to be applied to the spindle when rotating it manually, which leads to a decrease in the scraping quality of the bearing bush and reduces the reliability of the operation, failing to meet the actual operation requirements.

[0022] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. The specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. Specific details such as particular system structures and technologies are provided to facilitate a more thorough understanding of the embodiments of this utility model. The described embodiments are some, but not all, of the embodiments disclosed herein. However, those skilled in the art should understand that the present utility model can also be implemented in other embodiments without these specific details. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.

[0023] Example 1

[0024] refer to Figure 1 This embodiment provides a scraping spindle drive device, including a drive mechanism 1 and a rotation limit rod 2. The fixed end of the drive mechanism 1 is connected to the rotation limit rod 2, and the output end of the drive mechanism 1 is connected to the spindle 9 to be ground, so that the axis of the spindle 9 and the output end of the drive mechanism 1 are coaxial.

[0025] In actual use, the operator holds the rotation limit rod 2 to prevent it from rotating with the drive mechanism 1, or limits the bottom of the rotation limit rod 2 with a stop block to restrict the rotation of the drive mechanism 1 and ensure the drive of the main shaft 9.

[0026] The drive mechanism 1 is used to drive the drive spindle 9 to rotate around its axis, avoiding the application of a force perpendicular to its axis to the spindle 9. This ensures that the high point of the spindle 9 after grinding with the bearing is more reliable, thereby ensuring the scraping quality of the bearing. This reduces the intensity of manual labor while meeting the operational requirements.

[0027] Specifically, the drive mechanism 1 includes a rotary drive 4 and a reducer 5. The rotary drive 4 is connected to the reducer 5, and the reducer 5 is connected to the main shaft 9. The reducer 5 is used to increase the torque and reduce the speed, so as to ensure that the rotation of the main shaft 9 on the bearing is stable and reliable.

[0028] The rotation drive 4 can be an engine or a motor, preferably a motor. In this case, the drive mechanism 1 also includes a power supply a and a power switch b. The power supply a is electrically connected to the motor through the power switch b, and the rotation of the motor is controlled by operating the power switch b. The fixed end of the motor is connected to the outer wall of the reducer 5, and the output end of the motor is connected to the input end of the reducer 5.

[0029] The power switch b can be installed on the rotation limit rod 2 for easy operation; in this case, an insulating layer 8 can be fitted on the rotation limit rod 2 to ensure safe use.

[0030] To further explain, the rotation limit rod 2 is connected to the reducer 5. The rotation limit rod 2 is installed on the side of the reducer 5. The rotation limit rod 2 restricts the rotation of the fixed end of the rotation drive 4 through the outer wall of the reducer 5.

[0031] Preferably, the rotation limit rod 2 is positioned perpendicular to the axis of the output end of the reducer 5; more preferably, there are two rotation limit rods 2, which are installed on opposite sides of the reducer 5, allowing operators to hold the corresponding rotation limit rod 2 as needed to meet actual usage requirements; the power switch b can be installed on either rotation limit rod 2.

[0032] To further explain, in order to improve the efficiency of disassembly and assembly between the drive mechanism 1 and the main shaft 9, preferably, the reducer 5 and the main shaft 9 are detachably connected for easy operation.

[0033] In a further preferred embodiment, a spindle clamp 3 is provided at the output end of the reducer 5, and the output end of the reducer 5 is connected to the spindle clamp 3. The spindle clamp 3 can be disassembled and assembled with the spindle 9 as needed.

[0034] The spindle clamp 3 is illustrated using a cylindrical form as an example. Preferably, the output end of the reducer 5 is detachably connected to the spindle clamp 3.

[0035] One end of the spindle clamp 3 has a snap-fit ​​hole c. The snap-fit ​​hole c is coaxially set with the output end of the reducer 5 and the snap-fit ​​hole c cooperates with the output end of the reducer 5. The cross-sectional shape of the snap-fit ​​hole c can be a triangular or polygonal structure, so that the reducer 5 can drive the spindle clamp 3 to rotate through the snap-fit ​​hole c, thereby driving the spindle 9 to rotate.

[0036] To further ensure the reliability of the connection between the reducer 5 and the spindle clamp 3, it is preferable to open a limiting hole at the output end of the reducer 5 and set a locking limiting member 7 on the spindle clamp 3. The top of the locking limiting member 7 is located above the spindle clamp 3, and the bottom of the locking limiting member 7 extends into the interior of the snap-fit ​​hole c. When the output end of the reducer 5 is engaged with the snap-fit ​​hole c, the locking limiting member 7 snaps into the limiting hole, thereby ensuring a reliable and stable connection. At this time, the cross-section of the snap-fit ​​hole c can be circular.

[0037] The other end of the spindle clamp 3 is provided with a spindle connection port d, which is coaxial with the snap-fit ​​hole c to ensure that the spindle 9 and the output end of the reducer 5 are coaxial.

[0038] The cross-section of the spindle connection port d is C-shaped. An opening is reserved on the side of the spindle connection port d. A locking adjustment piece 6 is set at the opening position. The locking adjustment piece 6 is used to adjust the distance between the upper and lower ends of the opening, thereby realizing the adjustment of the diameter of the spindle connection port d. This makes the connection between the rotation drive 4 and the end of the spindle 9 more stable and reliable, and avoids the spindle 9 from slipping during rotation.

[0039] In practical use, it can quickly replace the corresponding spindle fixture 3 according to the specifications of the spindle 9, and at the same time ensure that the spindle fixture 3 and the spindle 9 are reliably connected, ensuring stable and reliable use.
