Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of conveying technology for long shaft oil immersion, in particular to a material conveying device for a long shaft full-automatic oil immersion machine. BACKGROUND

[0002] A long shaft refers to an axially shaped part with a length much greater than a diameter and a slender shape, which is widely used in mechanical transmission, steering, power output and other fields, and is one of the indispensable core components of various mechanical equipment and vehicles. In electric vehicles, typical long shaft parts mainly include drive half shafts for transmitting electric drive torque, transmission shafts for connecting motors and drive axles, and steering intermediate shafts for steering. These long shafts usually have the characteristics of large size, heavy weight and batch production. During the production and manufacturing process, these long shafts are mostly subjected to processes such as forging, machining or heat treatment. The bare metal surface of the shaft blank is prone to oxidation and rust during storage and transportation. Therefore, temporary rust prevention treatment is usually required after processing. One of the most commonly used methods in rust prevention treatment is to immerse the shaft in rust-proof oil to form a uniform protective oil film on the surface of the shaft blank, ensuring the quality of subsequent assembly and the protection performance during storage and transportation.

[0003] At present, the rust-proof oil immersion of such long shaft materials is mostly completed by a full-automatic oil immersion machine. The existing long shaft full-automatic oil immersion machine is usually equipped with a chain conveyor belt. The chain conveyor belt drives a rectangular placement frame containing long shafts to move along a set conveying path, so that the long shafts move through the oil pool arranged on the process section, realizing the overall immersion of the long shafts. However, in this structure, the long shafts are usually simply scattered in the rectangular placement frame. Due to the lack of effective limiting and separating measures, the long shafts are prone to rolling during the conveying process due to chain vibration or slope transition. After rolling, the long shafts collide and accumulate with each other, resulting in insufficient contact of the local surface of the long shafts with the rust-proof oil, uneven immersion and dead angles. When multiple long shafts are stacked together, the immersion depth and oil contact time of the surface shafts and the bottom shafts may be different. Even some shafts are lifted up due to clamping and cannot be completely immersed in the oil, causing inconsistent immersion and protection effects of the same batch of materials, affecting the batch quality stability. Moreover, when the long shafts are lifted out of the oil pool, excessive oil is attached to the stacked long shafts, causing waste of rust-proof oil and increasing the workload of subsequent oil dripping and wiping.

[0034] Before conveying, move bracket 1 so that mounting box 2 is located on the right side of the oil immersion machine, and make the lower cavity wall of the left opening of mounting box 2 flush with the conveying roller in the oil immersion machine (e.g., Figure 9 As shown, in the initial state, the push plate 92 is located on the right side of the belt conveyor 8, and the discharge cylinder 63 is located in the left half of the upper opening of the mounting box 2. First, the turnover baskets 3 used for oil soaking are placed on the belt conveyor 8 in sequence. Then, the shaft blanks are placed into the discharge cylinder 63. The width of the lower half of the discharge cylinder 63 matches the diameter of the shaft blank, while the width of the upper half of the discharge cylinder 63 can accommodate multiple rows of shaft blanks horizontally. The belt conveyor 8 is controlled to move the turnover baskets 3 backward to the position directly to the left of the push plate 92. Then, the electric telescopic rod 91 is controlled to push the push plate 92 to the left. Then, the push plate 92 pushes the turnover baskets 3 to the left and enters the left half of the inner cavity of the mounting box 2 until the turnover baskets 3 move to the position directly below the shaft feeding mechanism 6.

[0035] Then control the electric telescopic rod 64 contraction pull rectangular bearing frame 62 along the slip groove 61 to the right, while control drive motor 654 operation drive rotating drum 652, rotating drum 652 drive discharge groove 653 moves up directly above, located in the longitudinal arrangement of the blank in the discharge cylinder 63 down a grid, so that the first blank into the discharge groove 653, then the blank with rotating drum 652 rotates, while the rectangular bearing frame 62 again drive discharge cylinder 63 gradually right, discharge cylinder 63 to the right in the process will drive the installation in its rear top bar 662 first touch to the left of the first arc-shaped block 661 in the back row, then the arc-shaped block 661 top pressure top bar 662 forward, top bar 662 again drive discharge cylinder 63 forward movement, until the forward to the maximum stroke, at this time the discharge cylinder 63 drive cylinder sleeve 651 moves to the left of the first placement groove 42 directly above, rotating drum 652 through the discharge groove 653 drive shaft blank moves to the directly below, then the blank falls into the placement groove 42, at this time the shaft blank is close to the side of the side of the inclined state of the inclined distribution of the blank away from the side of the board 41, while the shaft blank away from the side of the board 41 first along the column 5, until the touch on the baffle, through the shaft blank placement after the inclined distribution makes in subsequent oil removal, the excess oil attached to the surface of the shaft blank can quickly flow away.

[0036] Then the electric telescopic rod 64 continues to pull the rectangular bearing frame 62 to the right, and then indirectly drive the discharge cylinder 63 right, discharge cylinder 63 then drive the top bar 662 gradually separated from the left of the first arc-shaped block 661 in the back row, then drive the discharge cylinder 63 gradually reset back to the middle under the action of the reset spring, rotating drum 652 continues to rotate drive discharge groove 653 moves to the directly above when the next shaft blank embedded in the discharge groove 653, discharge cylinder 63 continues to move to the right drive the front top bar 662 and the left of the first arc-shaped block 661 in the front row, then the arc-shaped block 661 top front top bar 662 to drive the discharge cylinder 63 to move backward, until the discharge cylinder 63 moves to the maximum stroke and located in the left of the second placement groove 42 directly above, at this time the downshift blank with rotating drum 652 moves to the six o'clock position of the rotating drum 652 and falls into the placement groove 42, then continue to move to the right of the discharge cylinder 63 again repeat the above steps, first reset back to the right, rotating drum 652 then drive the next shaft blank into the next placement groove 42.

[0037] The shaft blank is put into the placing groove 42 in turn by moving the discharge cylinder 63 right and moving forward and backward intermittently, and the shaft blank is put into the placing groove 42 in turn by rotating the discharge groove 653 driven by the rotating cylinder 652, which avoids the accumulation of the shaft blank, ensures that the oil blank surface can be fully immersed and coated with oil, and also avoids the rolling condition in the conveying process. Then, the second electric telescopic rod 91 is controlled to extend to push the push plate 92 left, and the push plate 92 pushes the turnover basket 3 filled with the shaft blank left to move out of the installation box 2 into the oil immersion machine, and finally the second electric telescopic rod 91 is controlled to retract to drive the push plate 92 to move right to reset to the initial position.

[0039] When the push plate 92 pushes the turnover basket 3 to move from the belt conveyor 8 to the left half area in the inner cavity of the installation box 2, the two spring sheets 73 in the left chuck set first contact the clamping column 72 located on the right, then pass the clamping column 72 on the right and abut against the clamping column 72 on the left. The inclined sections on both sides of the spring sheet 73 play a guiding role, ensuring that the clamping column 72 is smoothly inserted between the upper and lower spring sheets 73, and then the upper and lower spring sheets 73 abut on the outside of the clamping column 72, which can limit the position of the turnover basket 3 at this time, ensuring that the turnover basket 3 is in a stable state during the process of loading the long shaft. When the turnover basket 3 is moved by the push plate 92, the pushing force of the turnover basket 3 moving left is greater than the clamping force of the chuck set on the clamping column 72, so that the spring sheet 73 and the clamping column 72 are separated, and then the turnover basket 3 is smoothly moved left out of the installation box 2.

[0042] The long shaft in the placing groove 42 placed by the placing shaft mechanism 6 is abutted against the limiting wheel 432 located at the lower part after falling, then the arc-shaped rod 431 rotates around the lug when the long shaft presses the limiting wheel 432 at the lower part, the arc-shaped rod 431 drives the limiting wheel 432 located at the upper part to abut against the outer wall of the long shaft, at the same time, the top spring drives the top plate 106 to abut against the right part of the outer wall of the long shaft, thereby improving the stability of the long shaft entering the placing groove 42 and avoiding the rolling of the long shaft in the conveying process, (when the turnover basket 3 is located in the mounting box 2, the arc-shaped plate 103 abuts against the bottom of the cavity of the mounting box 2 and moves upward to the highest point, when the turnover basket 3 moves leftward to move out of the mounting box, the arc-shaped plate 103 is suspended and moves downward to the lowest point), during the process that the turnover basket 3 vertically downward enters the oil tank through the lifting frame on the oil immersion machine, the arc-shaped plate 103 abuts against the bottom of the cavity of the oil tank before the bottom of the turnover basket 3, then the arc-shaped plate 103 moves upward and drives the sliding rod to move upward, the sliding rod drives the sliding plate 102 to move upward, the sliding plate 102 drives the vertical plate 105 to move upward through the U-shaped frame 104, the vertical plate 105 drives the top plate 106 to move upward, and the top plate 106 rubs the long shaft to rotate in place in the oil tank during the upward movement.
