Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to a deburring tool for automotive output shafts. Background Technology

[0002] In automotive transmission systems, the output shaft, as a core component for transmitting power, directly affects transmission efficiency and overall vehicle stability due to its surface finish. During the machining process, burrs and flash are easily generated on the shaft surface and edges. If these defects are not removed promptly, they will not only exacerbate component wear during assembly but may also cause malfunctions such as oil circuit blockage and bearing jamming during long-term operation due to burr shedding. Therefore, the deburring process is a crucial step in the output shaft machining process.

[0003] Existing grinding equipment mostly relies on grinding components of fixed dimensions. For output shafts of different diameters, manual replacement of corresponding tooling or adjustment of the grinding component position is required. This is not only cumbersome and time-consuming, but also prone to poor grinding fit due to manual adjustment errors, making it difficult to guarantee a consistent deburring effect for shafts of different diameters. Secondly, most devices use a single transmission method, resulting in a single and insufficient contact between the output shaft and the grinding block. Repeated grinding is required to remove stubborn burrs, which not only prolongs the processing cycle but may also damage the surface precision of the shaft due to over-grinding. Furthermore, existing devices have a fixed range of output shaft height adaptation. When dealing with output shafts of different lengths or sizes, the relative movement height between the grinding component and the shaft cannot be flexibly adjusted, requiring redesign or modification of the device structure, increasing production input costs, and reducing the production line's compatibility with multiple product specifications. Utility Model Content

[0004] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a deburring fixture for automotive output shafts. This solves the problem of manually adjusting grinding components when grinding output shafts of different diameters, resulting in cumbersome and inaccurate adaptation operations. The spring and slide bar work together to automatically adapt and fit the grinding block to the output shaft, eliminating the need for manual adjustment. It also solves the problem of insufficient contact between the output shaft and the grinding block, leading to poor deburring effect and low processing efficiency. The motor-driven dual transmission system allows the vertical reciprocating motion of the output shaft to coordinate with the rotation of the grinding block, improving the fullness of contact. Furthermore, it solves the problem of limited tooling adaptability and difficulty in accommodating output shafts of different sizes. The sliding fixing block, combined with a multi-fixed-hole slide plate and different length rotating plates, allows for flexible adjustment of the output shaft's movement height range. Simultaneously, it solves the problem of low grinding accuracy and large processing errors caused by unstable component movement. The support plate and limit rod respectively restrict the movement direction of the slide plate and mounting plate, ensuring movement stability.

[0005] This utility model also provides a deburring fixture for an automotive output shaft as described above, comprising: a base, a fixed plate fixedly connected to the upper surface of the base by a rod, a rotating plate rotatably connected to the inner side of the fixed plate, a sliding rod fixedly connected to the side surface of the rotating plate by a spring, and a grinding block fixedly connected to the end of the sliding rod away from the rotating plate.

[0006] A motor is fixedly connected to the lower wall of the base. A rotating shaft is fixedly connected to the output end of the motor. A rotating plate is detachably connected to the end of the rotating shaft away from the motor. A sliding plate is movably connected to the upper surface of the rotating plate. A fixing block is detachably connected to the side surface of the sliding plate. A mounting plate is rotatably connected to the fixing block via a connecting rod. Through these components, the grinding block, with the cooperation of a spring and a sliding rod, can automatically adapt to the output shaft diameter and fit tightly without manual adjustment, exhibiting strong adaptability and stable grinding of output shafts of different diameters. The fixture adopts a motor-driven dual-drive system, which both drives the output shaft to reciprocate vertically and causes the grinding block to rotate around the output shaft. The two work together to ensure repeated and thorough contact between the output shaft and the grinding block, significantly improving the deburring effect and efficiency.

[0007] According to the present invention, a deburring fixture for an automotive output shaft has a belt drivingly connected to the side surface of a first rotating shaft, and a second rotating shaft drivingly connected to the side surface of the belt. The belt enables the first rotating shaft to drive the second rotating shaft to rotate.

[0008] According to the present invention, a deburring fixture for automotive output shafts comprises a second rotating shaft, one end of which is rotatably connected to a base, and the other end of which is fixedly connected to a rotating rod. The rotating shaft drives the rotating rod to rotate.

[0009] According to the present invention, a deburring fixture for automotive output shafts includes a gear fixedly connected to the end of the rotating rod away from the rotating shaft, the side surface of which meshes with the rotating disk. This allows the rotating rod to drive the gear to rotate, thereby causing the rotating disk to rotate on the fixed disk.

[0010] According to the present invention, a deburring fixture for automotive output shafts includes multiple symmetrically distributed sliding rods, the side surfaces of which are slidably connected to a fixed plate. This allows the sliding rods to slide along the fixed plate to adapt to the diameter of the output shaft.

[0011] According to the present invention, a deburring fixture for automotive output shafts includes a support plate fixedly connected to the upper top wall of the base, and a sliding groove plate whose side surface is slidably connected to the support plate. The support plate limits one end of the sliding groove plate, allowing it to move only horizontally along the support plate.

[0012] According to the present invention, a deburring fixture for automotive output shafts includes a limiting rod fixedly connected to the upper surface of the base, and the side surface of the limiting rod slidably connected to the mounting plate. The limiting rod restricts the movement of the mounting plate, ensuring that the mounting plate can only move vertically.

[0013] According to the present invention, a deburring fixture for automotive output shafts comprises a connecting rod, one end of which is rotatably connected to a fixed block, and the other end of which is rotatably connected to a mounting plate. By connecting the fixed block and the mounting plate via the connecting rod, when the sliding plate moves the fixed block, the fixed block can drive the mounting plate to reciprocate along the vertical direction via the connecting rod.

[0014] Beneficial effects:

[0015] This automotive output shaft deburring fixture utilizes a grinding block that automatically adapts to the output shaft diameter and fits snugly with the aid of a spring and sliding rod, eliminating the need for manual adjustment. Its strong adaptability allows for stable grinding of output shafts of varying diameters. The fixture employs a dual-drive system driven by a motor, which simultaneously drives the output shaft in vertical reciprocating motion and causes the grinding block to rotate around the output shaft. This synergy ensures repeated and thorough contact between the output shaft and the grinding block, significantly improving deburring effectiveness and efficiency. By using a sliding fixing block in conjunction with a multi-hole sliding groove plate and replacing rotating plates of different lengths, the output shaft's movement height can be flexibly adjusted to accommodate different sizes of output shafts, offering excellent versatility. Furthermore, a support plate and a limit rod respectively restrict the movement direction of the sliding groove plate and the mounting plate, ensuring stable movement of all components, effectively improving grinding precision and reducing machining errors.

[0024] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0025] Reference Figure 1-5 This utility model provides a deburring tool for an automotive output shaft, comprising: a base 1, a fixed plate 2 fixedly connected to the upper surface of the base 1 by a rod, a rotating plate 3 rotatably connected to the inner side of the fixed plate 2, a sliding rod 4 fixedly connected to the side surface of the rotating plate 3 by a spring 6, multiple sliding rods 4 symmetrically distributed, the side surface of the sliding rod 4 slidably connected to the fixed plate 2, and a grinding block 5 fixedly connected to the end of the sliding rod 4 away from the rotating plate 3;

[0026] Specifically, a spring 6 with a suitable elastic coefficient is installed between the slide rod 4 and the rotating disk 3. A grinding block 5 is installed at the end of the slide rod 4. When the fixture starts working, the rotating disk 3 will rotate along the fixed disk 2. Then the fixed disk 2 will drive the output shaft fixed on the fixed disk 2 to pass through the middle of the rotating disk 3 via the grinding block 5. At this time, the output shaft will push the grinding block 5 open. The grinding block 5 will then adapt to the diameter of the output shaft and fit against the output shaft under the action of the slide rod 4 and the spring 6. The rotating disk 3 drives the grinding block 5 to rotate along the surface of the output shaft, thereby removing the burrs on the output shaft.

[0027] A motor 9 is fixedly connected to the lower bottom wall of the base 1. A rotating shaft 10 is fixedly connected to the output end of the motor 9. A rotating plate 11 is detachably connected to the end of the rotating shaft 10 away from the motor 9. A sliding plate 12 is movably connected to the upper surface of the rotating plate 11. A fixing block 16 is detachably connected to the side surface of the sliding plate 12. A mounting plate 7 is rotatably connected to the fixing block 16 through a connecting rod 17. One end of the connecting rod 17 is rotatably connected to the fixing block 16, and the other end of the connecting rod 17 away from the fixing block 16 is rotatably connected to the mounting plate 7.

[0028] Specifically, before use, the output shaft is fixed to the mounting plate 7 with screws or other fixing parts. During use, the motor 9 drives the rotating plate 11 to rotate through the rotating shaft 10. The protrusion on the rotating plate 11 slides along the slide groove on the slide plate 12, thereby driving the slide plate 12 to reciprocate linearly. At this time, the fixing block 16 on the slide plate 12 also moves with the slide plate 12 and drives the mounting plate 7 to reciprocate vertically through the connecting rod 17, so that the mounting plate 7 can drive the output shaft to move synchronously, so that the output shaft can repeatedly contact the grinding block 5, improving the deburring effect. The slide plate 12 has multiple fixing holes, which can be fixed with bolts after sliding the fixing block 16. Different lengths of rotating plates 11 can be used to adjust the height range of the mounting plate 7 to adapt to different sizes of output shafts.

[0029] A belt 13 is connected to the side surface of the rotating shaft 10, and a rotating shaft 14 is connected to the side surface of the belt 13. One end of the rotating shaft 14 is rotatably connected to the base 1, and the other end of the rotating shaft 14 is fixedly connected to a rotating rod 15. A gear 19 is fixedly connected to the end of the rotating rod 15 away from the rotating shaft 14, and the side surface of the gear 19 meshes with the rotating disk 3.

[0030] Specifically, the base 1 is also equipped with two sets of rotating shafts 14. Each set of rotating shafts 14 is connected to a gear 19 through a rotating rod 15. The two sets of rotating shafts 14 are connected to the rotating shaft 10 through a belt 13. When the rotating shaft 10 rotates, the belt 13 will drive the two sets of rotating shafts 14 to rotate synchronously, so that the two gears 19 mesh with the teeth below the rotating disk 3 and drive the rotating disk 3 to rotate, which is used to drive the grinding block 5 to grind and remove burrs from the output shaft.

[0031] A support plate 18 is fixedly connected to the upper top wall of the base 1. The side surface of the sliding plate 12 is slidably connected to the support plate 18. A limit rod 8 is fixedly connected to the upper surface of the base 1. The side surface of the limit rod 8 is slidably connected to the mounting plate 7.

[0032] Specifically, the base 1 is provided with a support plate 18, and one end of the slide plate 12 passes through the support plate 18. Through the restriction and support of the support plate 18, the slide plate 12 moves with the rotating plate 11 and can only reciprocate in a straight line. There are also two limiting rods 8 above the base 1, which pass through the mounting plate 7 to limit it. When the mounting plate 7 moves with the connecting rod 17, it is limited by the limiting rods 8, so that the mounting plate 7 can only move in a vertical direction.

[0033] Working principle: Starting motor 9 drives shaft 10 to rotate. On one hand, shaft 10 drives rotating plate 11 to rotate. The protrusion of rotating plate 11 slides along the groove of sliding plate 12. Due to the limit of support plate 18, sliding plate 12 performs linear reciprocating motion, driving fixed block 16 to move synchronously. Fixed block 16 pulls mounting plate 7 through connecting rod 17. Under the restriction of limit rod 8, mounting plate 7 drives the output shaft fixed on it to perform perpendicular reciprocating motion. On the other hand, shaft 10 drives shaft 14 to rotate through belt 13. Shaft 14 drives gear 19 through rotating rod 15. Gear 19 meshes with rotating disk 3, causing rotating disk 3 to rotate along fixed disk 2. Spring 6 on rotating disk 3 connects to sliding rod 4. When the output shaft passes through rotating disk 3, it pushes open grinding block 5. Spring 6 causes grinding block 5 to adhere to the output shaft. Rotating disk 3 drives grinding block 5 to rotate, cooperating with the vertical reciprocating motion of the output shaft to achieve burr removal.

[0034] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
