Description

Technical Field

[0001] This utility model relates to the field of material rack technology, and more specifically, to a turnover material rack for processing mechanical parts. Background Technology

[0002] In existing turnover rack technology for machining mechanical parts, the inconvenience of conveying materials at both ends of the bin and the inconvenience of fixing the bin's position have become major bottlenecks restricting production efficiency and operational convenience.

[0003] Traditional turnover racks typically use a unidirectional slide design, which can only realize the one-way conveying of the boxes. When it is necessary to pick up or put down the boxes from two directions, the operator must go around to the other end of the rack to operate, or turn the entire rack around and adjust it. This not only increases the operation time, but also increases the labor intensity. In the factory environment with a compact production line layout, this unidirectional conveying structure seriously restricts the space utilization efficiency and production line flexibility.

[0004] Traditional material racks typically use simple clips, blocks, or friction pads to fix the position of the material boxes. These fixing methods either lack sufficient fixing force, causing the material boxes to slide in a vibrating environment, or they are too tight, making it difficult to pick up and put down the material boxes. Especially in scenarios where the position of the material boxes needs to be adjusted frequently, such fixing mechanisms often require the use of tools, which greatly reduces production efficiency.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a turnover rack for processing mechanical parts, comprising a frame, an inclined sliding mechanism, a wheel fixing mechanism, and a stabilizing auxiliary mechanism. The inclined sliding mechanism includes an inclined frame, guide wheels, an adjusting frame, adjusting wheels, an adjusting sleeve, and a rotating rod. The inclined frame is obliquely mounted on the frame, multiple sets of guide wheels are mounted on the inclined frame, the adjusting frame is mounted at one end of the inclined frame, and the rotating rod is mounted on the adjusting wheel. The rotating rod is rotatably configured to cooperate with the inclined frame. The adjusting sleeve is mounted at one end of the adjusting frame, and the other end of the rotating rod is rotatably configured inside the adjusting frame. The wheel fixing mechanism includes an annular groove, a spinning rod, a thrust spring, a rotating sleeve, and a spinning groove. The annular groove is located on the side wall of the rotating rod. The spinning rod is laterally slidably mounted on the side wall of the adjusting sleeve. The rotating sleeve is rotatably mounted on the side wall of the adjusting sleeve. The spinning groove is located on the inner wall of the rotating sleeve. The spinning groove presses against the spinning rod and extends into the annular groove, and the surface of the annular groove is designed to increase friction. The thrust spring is installed between the spinning rod and the outer wall of the adjusting sleeve.

[0009] The present invention is further configured such that the stabilizing auxiliary mechanism includes a top ring, a ball block, an outer fixed ring, a counter-shrinking block, a fixing block, and a counter-shrinking spring. The top ring is fixedly installed on the outer wall of the adjusting sleeve. The fixing block is arranged in a ring at the bottom end of the outer fixed ring. Multiple sets of counter-shrinking blocks are slidably installed at the bottom end of the outer fixed ring. The counter-shrinking spring is installed between the counter-shrinking blocks and the fixing block. The top ring is installed at the top end of the rotating sleeve. The ball block is installed at the top end of the top ring. The ball block passes between the counter-shrinking blocks and the fixing block in sequence, so that the rotating sleeve rotates stably.

[0010] The present invention is further configured such that a base frame is installed at the bottom end of the frame, and bottom wheels are installed around the bottom end of the base frame. The bottom wheels are installed around the base frame, making the entire material rack easy to move and improving the flexibility of use.

[0011] The present invention is further configured such that mounting buckles are installed at both ends of the inclined frame, and the mounting buckles are detachably installed on the vehicle frame. The mounting buckles are installed at both ends of the inclined frame to realize the detachable connection between the inclined frame and the vehicle frame, which facilitates maintenance and adjustment.

[0012] The present invention is further provided that a connecting plate is installed at the bottom end of the adjusting sleeve, and the connecting plate is fixedly installed on the side wall of the adjusting frame. The connecting plate connects the bottom of the adjusting sleeve and the side wall of the adjusting frame, thereby enhancing the connection strength and ensuring structural stability.

[0013] The present invention is further configured such that multiple sets of inclined frames are provided, and the material box is slidably mounted on the bottom wheel of the inclined frame. The adjusting wheel at one end of the inclined frame that does not rotate is in contact with the bottom of the material box and is rubbed. The inclined frame is installed obliquely on the frame, and gravity is used to provide natural sliding power for the material box, saving energy and realizing automatic conveying of the material box.

[0014] The present invention is further configured such that a support ring is installed at the bottom end of the rotating sleeve, and the support ring is rotatably configured to support the bottom end and the top end of the connecting plate. The support ring is installed at the bottom of the rotating sleeve and cooperates with the connecting plate to support rotation, thereby reducing wear and extending service life.

[0015] The present invention is further configured such that a centripetal rail is installed at the bottom end of the outer fixed ring, and the shrink block is configured to slide centripetally with the centripetal rail. The centripetal rail is installed at the bottom of the outer fixed ring and slides centripetally with the shrink block to ensure the accurate movement trajectory of the shrink block.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, this utility model provides a turnover rack for machining mechanical parts, which has the following beneficial effects:

[0018] This utility model is equipped with an inclined sliding mechanism. The inclined sliding mechanism uses gravity to achieve natural sliding conveying of the material box through the inclined frame and the cooperation of multiple sets of guide wheels, which saves energy costs. The adjustment wheel is set to contact the bottom of the material box with friction, which can accurately control the sliding speed and stopping position of the material box. The rotating rod cooperates with the inclined frame to rotate, which can flexibly adjust the position of the adjustment wheel. The detachable design of the mounting buckle facilitates the maintenance and replacement of the inclined frame, improving the maintenance convenience and usage flexibility of the equipment.

[0019] This invention features a wheel fixing mechanism that controls the forward and backward movement of the spinning rod via a rotating sleeve, enabling rapid locking and releasing of the rod's position. When the spinning rod extends into the annular groove, a reliable friction lock is formed, preventing accidental rotation of the adjusting wheel. A counter-spring provides automatic reset force, ensuring a rapid response during release. This design allows for locking and unlocking operations without tools, greatly improving the convenience and reliability of adjusting the material box position and solving the problem of inconvenient fixation of traditional material rack positions.

[0020] This invention incorporates a stabilizing auxiliary mechanism. Through the ingenious cooperation of a ball block, a shrinking block, and a fixing block, the stabilizing auxiliary mechanism forms a graded positioning mechanism. As the ball block passes through the gap between the shrinking block and the fixing block in sequence, the centripetal pressure provided by the shrinking spring causes the shrinking block to form a ratchet effect, ensuring that the rotating sleeve stays stably at a specific angle position. The sliding cooperation between the centripetal rail and the shrinking block ensures the accuracy of the motion trajectory. This design effectively prevents the rotating sleeve from rotating unexpectedly due to vibration or external force, improves the stability and positioning accuracy of the locking operation, and ensures the reliability of the fixed position of the material box.

[0030] Please see Figures 1-5A turnover rack for machining mechanical parts includes a frame 1, an inclined sliding mechanism, a wheel fixing mechanism, and a stabilizing auxiliary mechanism. The inclined sliding mechanism includes an inclined frame 2, guide wheels 3, an adjusting frame 4, adjusting wheels 5, an adjusting sleeve 6, and a rotating rod 7. The inclined frame 2 is obliquely mounted on the frame 1. Multiple sets of guide wheels 3 are mounted on the inclined frame 2. The adjusting frame 4 is mounted on one end of the inclined frame 2. The rotating rod 7 is mounted on the adjusting wheels 5 and is rotatably configured to cooperate with the inclined frame 2. The adjusting sleeve 6 is mounted on one end of the adjusting frame 4, and the other end of the rotating rod 7 is on the adjusting frame. The inner rotation setting of 4 includes a wheel fixing mechanism comprising an annular groove 8, a spinning rod 9, a thrust spring 10, a rotating sleeve 11, and a spinning groove 12. The annular groove 8 is located on the side wall of the rotating rod 7. The spinning rod 9 is laterally slidably mounted on the side wall of the adjusting sleeve 6. The rotating sleeve 11 is limited and rotatably mounted on the side wall of the adjusting sleeve 6. The spinning groove 12 is located on the inner wall of the rotating sleeve 11. The spinning groove 12 presses against the spinning rod 9 and extends into the annular groove 8. The surface of the annular groove 8 is designed to increase friction. The thrust spring 10 is installed between the spinning rod 9 and the outer wall of the adjusting sleeve 6.

[0031] In this embodiment, the inclined sliding mechanism is obliquely mounted on the frame 1 via an inclined frame 2, providing an inclined sliding channel for the material box. Multiple sets of guide wheels 3 are mounted on the inclined frame 2, and the material box slides along the guide wheels 3 under the action of gravity. An adjusting frame 4 is mounted on one end of the inclined frame 2, and the sliding speed of the material box is controlled by adjusting wheels 5. A rotating rod 7 is mounted on the adjusting wheels 5 and rotates in cooperation with the inclined frame 2. When it is necessary to adjust the sliding resistance of the adjusting wheels 5, the contact friction with the bottom of the material box is changed, thereby controlling the sliding speed and stopping position of the material box. A wheel fixing mechanism is also included. Used to lock the rotation position of the rotating rod 7. When it is necessary to fix the position of the adjusting wheel 5, the rotating sleeve 11 rotates to press the spinning groove 12 against the spinning rod 9. The spinning rod 9 slides laterally into the annular groove 8 on the side wall of the rotating rod 7. Since the surface of the annular groove 8 is designed to increase friction, the spinning rod 9 and the annular groove 8 form a reliable friction lock to prevent the rotating rod 7 from rotating accidentally. When adjustment is required, the rotating sleeve 11 is rotated in the opposite direction, and the push spring 10 pushes the spinning rod 9 out of the annular groove 8, releasing the rotating rod 7 so that it can rotate freely for adjustment.

[0032] The stabilizing auxiliary mechanism includes a top ring 13, a ball block 14, an outer fixed ring 15, a counter-shrinking block 16, a fixing block 17, and a counter-shrinking spring 18. The top ring 13 is fixedly installed on the outer wall of the adjusting sleeve 6. The fixing block 17 is arranged in a ring at the bottom end of the outer fixed ring 15. Multiple sets of counter-shrinking blocks 16 are slidably installed at the bottom end of the outer fixed ring 15. The counter-shrinking spring 18 is installed between the counter-shrinking blocks 16 and the fixing block 17. The top ring 13 is installed at the top end of the rotating sleeve 11. The ball block 14 is installed at the top end of the top ring 13. The ball block 14 passes between the counter-shrinking blocks 16 and the fixing block 17 in sequence, so that the rotating sleeve 11 rotates stably.

[0033] In this embodiment, the stabilizing auxiliary mechanism ensures the stability and positioning accuracy of the rotating sleeve 11. The top ring 13 is fixed to the outer wall of the adjusting sleeve 6, and the ball block 14 is installed on the top of the top ring 13. When the rotating sleeve 11 rotates, the ball block 14 passes through the gap between the counterweight block 16 and the fixed block 17 in sequence. The counterweight spring 18 provides centripetal pressure to the counterweight block 16. The passage of the ball block 14 causes the counterweight block 16 to be pushed outward to form a graded positioning point, similar to a ratchet mechanism, to ensure that the rotating sleeve 11 stays stably at a specific angle position, preventing accidental rotation caused by vibration or external force, and improving the reliability of locking and releasing operations.

[0034] Please see Figures 1-5 As a supplementary embodiment of a turnover rack for processing mechanical parts, which includes a slanted sliding mechanism, a wheel fixing mechanism, and a stabilizing auxiliary mechanism: A base frame 19 is installed at the bottom end of the frame 1, and bottom wheels 20 are installed around the bottom end of the base frame 19. Mounting buckles 21 are installed at both ends of the slanted frame 2, and the mounting buckles 21 are detachably installed on the frame 1. A connecting plate 22 is installed at the bottom end of the adjusting sleeve 6, and the connecting plate 22 is fixedly installed on the side wall of the adjusting frame 4. Multiple sets of slanted frames 2 are provided, and the material box is slidably set on the bottom wheels 20 of the slanted frame 2. The adjusting wheel 5 at one end of the slanted frame 2, which is not rotated, is in contact with the bottom of the material box and rubs against it. A support ring 23 is installed at the bottom end of the rotating sleeve 11, and the support ring 23 is rotatably supported by the bottom end of the connecting plate 22 and the top end of the connecting plate 22. A radial rail 24 is installed at the bottom end of the outer fixed ring 15, and the shrinking block 16 is slidably set in conjunction with the radial rail 24.

[0035] More specifically, firstly, the material box is placed on the guide wheel 3 of the inclined frame 2 and slides downward along the inclined sliding mechanism under the action of gravity. The operator adjusts the position of the rotating rod 7 through the wheel fixing mechanism as needed, changing the contact friction between the adjusting wheel 5 and the bottom of the material box, and controlling the sliding speed of the material box. When the appropriate position is reached, the wheel fixing mechanism is operated by rotating the sleeve 11, and the spinning rod 9 extends into the annular groove 8 to lock the position of the rotating rod 7. The stabilizing auxiliary mechanism ensures the stability of the locked state and prevents accidental loosening. The material box slides orderly to the designated position at the set speed, realizing the orderly turnover and storage of mechanical parts. The base frame 19 and the bottom wheel 20 make the entire device easy to move. The mounting buckle 21 design makes the inclined frame 2 detachable, which is convenient for maintenance and adjustment. This design realizes precise control and reliable locking of the material box sliding speed, improving the material turnover efficiency and safety in the mechanical parts processing process.

[0036] In summary, when the overall equipment is in use or operation: when the inclined sliding mechanism is required to operate, the inclined sliding mechanism is installed obliquely on the frame 1 via the inclined frame 2, providing an inclined sliding channel for the material box. Multiple sets of guide wheels 3 are installed on the inclined frame 2, and the material box slides along the guide wheels 3 under the action of gravity. The adjusting frame 4 is installed at one end of the inclined frame 2, and the sliding speed of the material box is controlled by the adjusting wheel 5. The rotating rod 7 is installed on the adjusting wheel 5 and rotates in cooperation with the inclined frame 2. When it is necessary to adjust the sliding resistance of the adjusting wheel 5, the contact friction with the bottom of the material box is changed, thereby controlling the sliding speed and stopping position of the material box.

[0037] When the wheel fixing mechanism is in operation, it is used to lock the rotation position of the rotating rod 7. When the position of the adjusting wheel 5 needs to be fixed, the rotating sleeve 11 rotates to press the spinning groove 12 against the spinning rod 9. The spinning rod 9 slides laterally into the annular groove 8 on the side wall of the rotating rod 7. Since the surface of the annular groove 8 is designed to increase friction, the spinning rod 9 and the annular groove 8 form a reliable friction lock to prevent the rotating rod 7 from rotating accidentally. When adjustment is required, the rotating sleeve 11 is rotated in the opposite direction, and the push spring 10 pushes the spinning rod 9 out of the annular groove 8, releasing the rotating rod 7 so that it can rotate freely for adjustment.

[0038] When the stabilizing auxiliary mechanism is required to operate, it ensures the stability and positioning accuracy of the rotating sleeve 11. The top ring 13 is fixed to the outer wall of the adjusting sleeve 6, and the ball block 14 is installed on the top of the top ring 13. When the rotating sleeve 11 rotates, the ball block 14 passes through the gap between the counter-shrink block 16 and the fixed block 17 in sequence. The counter-shrink spring 18 provides centripetal pressure to the counter-shrink block 16. The passage of the ball block 14 causes the counter-shrink block 16 to be pushed outward, forming a graded positioning point, similar to a ratchet mechanism, to ensure that the rotating sleeve 11 stays stably at a specific angle position, preventing accidental rotation caused by vibration or external force, and improving the reliability of locking and releasing operations.

[0039] First, the material box is placed on the guide wheel 3 of the inclined frame 2 and slides downward along the inclined sliding mechanism under the action of gravity. The operator adjusts the position of the rotating rod 7 through the wheel fixing mechanism as needed, changes the contact friction between the adjusting wheel 5 and the bottom of the material box, and controls the sliding speed of the material box. When the appropriate position is reached, the wheel fixing mechanism is operated by rotating the sleeve 11, and the spinning rod 9 extends into the annular groove 8 to lock the position of the rotating rod 7. The stabilizing auxiliary mechanism ensures the stability of the locked state and prevents accidental loosening. The material box slides orderly to the designated position at the set speed, realizing the orderly turnover and storage of mechanical parts. The base frame 19 and the bottom wheel 20 make the entire device easy to move. The mounting buckle 21 design makes the inclined frame 2 detachable, which is convenient for maintenance and adjustment. This design realizes precise control and reliable locking of the material box sliding speed, and improves the material turnover efficiency and safety in the mechanical parts processing process.

For all the fixed connections mentioned above, welding is preferred.
