Description

Technical Field

[0001] This application relates to the field of material conveying technology, and in particular to a rotary conveyor rack. Background Technology

[0002] In the field of engine manufacturing, quality inspection is a crucial link in ensuring engine performance and reliability. With the continuous development of engine technology, the quality requirements for various engine components are becoming increasingly stringent. As a vital component of the engine, the quality of the engine block's machined surfaces, such as the presence of defects like shrinkage cavities and cracks, directly affects the overall performance of the engine. Therefore, accurate and efficient quality inspection of the engine block is of paramount importance for improving engine production quality and efficiency. This not only relates to the normal operation of the engine but also impacts the development of the entire automotive industry and the user experience. By continuously improving and optimizing engine block inspection technology, the incidence of engine failures can be effectively reduced, thereby enhancing the safety and reliability of automobiles.

[0003] Traditionally, engine block quality inspection is done manually. Workers typically remove the engine block from the horizontal rolling assembly, hold it, and flip it over to carefully inspect the quality of each machined surface. After inspection, the engine block is placed back on the rolling assembly. This method has long been a common inspection practice in the engine manufacturing industry and, to a certain extent, meets the basic requirements for engine block quality inspection. However, with the continuous expansion of engine production scale and increasingly stringent quality requirements, this traditional method has gradually revealed some limitations.

[0004] Traditional manual inspection methods have obvious drawbacks. Workers need to frequently pick up and put down the engine block from the roller conveyor and perform flipping operations, which makes the labor intensity extremely high. Long-term repetitive operations can easily lead to worker fatigue, thereby affecting the accuracy and efficiency of the inspection. In addition, during the process of picking up and putting down the engine block, there is a high probability that the engine block will collide with other objects, which can easily cause damage to the engine block, thereby affecting the quality of the engine block and its subsequent performance. Utility Model Content

[0005] To address the problems of complex and difficult-to-operate traditional manual inspection procedures for engine blocks, which affect accuracy and efficiency during inspection, and the risk of damage to the engine block affecting its quality and performance, this application provides a rotary conveyor rack.

[0006] The rotary conveyor rack provided in this application adopts the following technical solution: A rotary conveyor rack includes a base, a sheet metal shell rotatably connected to the base, a drive mechanism mounted on the sheet metal shell, a transmission mechanism mounted on the drive mechanism, and a frame structure arranged parallel to the transmission direction of the transmission mechanism. The frame structure and the sheet metal shell are rotatably coupled through auxiliary parts. The drive mechanism is used to drive the transmission mechanism to drive, and the frame structure is used to place the engine cylinder block for transmission detection.

[0007] By adopting the above technical solution, the rotational transport and placement inspection of the engine cylinder block can be realized, avoiding manual handling of the engine cylinder block, reducing labor intensity and the risk of bumps and injuries, and enabling rotational inspection of the engine cylinder block.

[0008] Optionally, the drive mechanism includes a support mounted on a sheet metal shell and a motor mounted on the support. The output end of the motor is connected to a transmission mechanism, and the sheet metal shell and the base are connected by a rotating shaft.

[0009] By adopting the above technical solution, using an electric motor as the power source, the motor drives the transmission mechanism after starting, and the sheet metal shell and the base rotate and cooperate. During testing, it is convenient to rotate the engine block along the Z-axis direction, and it is easy to observe different positions of the engine block circumferentially without a lot of manual handling.

[0010] Optionally, the transmission mechanism includes an equal-diameter bevel gear set mounted on the output end of the motor, a connecting shaft mounted on the equal-diameter bevel gear set, a worm gear assembly mounted on the connecting shaft, and a connecting rod mounted on the worm gear assembly, wherein the connecting rod is connected to the auxiliary components.

[0011] By adopting the above technical solution, the motor output power is transmitted to the connecting shaft via the equal diameter bevel gear set, and then to the connecting rod via the worm gear assembly. The connecting rod is connected to the auxiliary parts, realizing the effective transmission of power. One motor can realize three degrees of freedom of rotation, which can transform the rotational motion of one motor into the rotational motion of four rollers. It can also enable the rotating conveyor to rotate 360° around X and Y, and realize the synchronous motion of two measuring mechanisms through the synchronous belt pulley.

[0012] Optionally, the auxiliary component includes a roller mounted on the connecting rod and an auxiliary wheel rotatably arranged on the sheet metal shell. The roller is rotatably arranged on the sheet metal shell. The inner diameter of the frame structure is in rolling engagement with the auxiliary wheel, and the outer diameter of the frame structure is in rolling engagement with the roller. The diameter of the auxiliary wheel is smaller than the diameter of the roller.

[0013] By adopting the above technical solution, the rollers and auxiliary wheels roll in cooperation with the outer and inner diameters of the frame structure, respectively, enabling the frame structure to rotate stably. This facilitates the placement and transmission of the test engine block. Furthermore, the diameter of the auxiliary wheel is smaller than that of the roller, which contributes to the stability of the structural layout and rotation.

[0014] Optionally, the frame structure includes a frame body, a load-bearing beam, a pad plate, a positioning block, and a load-bearing plate. The inner diameter of the frame body is in rolling engagement with auxiliary wheels, and the outer diameter of the frame body is in rolling engagement with rollers. The pad plate is installed on the side wall of the frame body. The load-bearing plate and the pad plate are connected by an assembly. The load-bearing beam is installed on the load-bearing plate, and the positioning block is installed on the side of the load-bearing plate away from the load-bearing beam.

[0015] By adopting the above technical solution, the frame structure can rotate flexibly in the horizontal direction through the rolling cooperation of the frame body with auxiliary wheels and rollers, which facilitates the inspection of the engine cylinder block. The positioning block is fixed on the load-bearing plate for positioning on both sides. The engine cylinder block is fixed to the load-bearing beam by positioning pins for easy fixing and inspection.

[0016] Optionally, the worm gear assembly includes a worm gear mounted on a connecting shaft and a worm meshing with the worm gear. The worm is mounted on a connecting rod, and brackets for limiting the movement are provided on both sides of the worm gear.

[0017] By adopting the above technical solution, the motor rotates the bevel gear as the power source, and through the mechanical transmission of the equal diameter bevel gear and the worm gear, a single motor can achieve three degrees of freedom of rotation; limit brackets are set on both sides of the worm gear to limit the worm gear and ensure the stability of the transmission.

[0018] Optionally, the equal diameter bevel gear set includes a longitudinal equal diameter bevel gear mounted on the motor output end and a transverse equal diameter bevel gear meshing with the longitudinal equal diameter bevel gear, wherein the transverse equal diameter bevel gear is connected to a connecting shaft.

[0019] By adopting the above technical solution, the motor drives the longitudinal equal-diameter bevel gear to rotate. The longitudinal equal-diameter bevel gear meshes with the transverse equal-diameter bevel gear, transmitting the rotational motion of the motor to the connecting shaft. In turn, the connecting shaft drives the subsequent worm gear assembly and other components to move, realizing the transformation of the rotational motion of one motor into the rotational motion of multiple components. Furthermore, through the meshing transmission of the equal-diameter bevel gears, the effective transmission of power and the change of motion direction can be achieved.

[0020] Optionally, the assembly includes a baffle mounted on a pad, the load-bearing plate and the baffle being connected by a fixing pin, and the baffle being triangular in shape.

[0021] By adopting the above technical solution, using triangular baffles and fixing pins to connect the pads and load-bearing plates, the stability of the frame structure can be enhanced, allowing the rotating conveyor rack to be placed more firmly and to transport the test engine cylinder block more securely.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The drive mechanism drives the transmission mechanism, enabling the frame structure to rotate around the X and Y degrees of freedom, which facilitates the inspection of each machined surface of the engine block and solves the problem of high labor intensity of manual inspection; 2. The frame structure and sheet metal shell are rotated and connected by auxiliary parts, which allows the engine block to be placed and transported stably, avoiding bumps and damage to the engine block during loading and unloading. 3. By using transmission mechanisms such as equal-diameter bevel gear sets and worm gear assemblies, a single motor can drive the movement of multiple components, enabling accurate and efficient inspection of engine block quality and improving testing efficiency and accuracy.

[0032] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0033] This application discloses a rotary conveyor rack.

[0034] Reference Figure 1 The system includes a base 1, a sheet metal shell 2, a drive mechanism 3, a transmission mechanism 4, and a frame structure 5. The sheet metal shell 2 is rotatably connected to the base 1. The drive mechanism 3 is mounted on the sheet metal shell 2, and the transmission mechanism 4 is mounted on the drive mechanism 3. The frame structure 5 is arranged along the axis of the transmission mechanism 4, and the frame structure 5 and the sheet metal shell 2 are rotatably engaged through an auxiliary component 45. The drive mechanism 3 is used to drive the transmission mechanism 4, and the frame structure 5 is used to place the engine block for transmission and testing. This achieves the effect of rotating and transporting the engine block through mechanical transmission, which facilitates inspection, reduces labor intensity, and minimizes bumps and injuries. The drive mechanism 3 provides power, which is transmitted through the transmission mechanism 4, enabling the frame structure 5 to rotate stably and avoiding frequent manual handling of the engine block.

[0035] See Figure 2 and Figure 5 As shown, the drive mechanism 3 includes a support 31 and a motor 32. The support 31 is mounted on the sheet metal shell 2 and has a U-shaped structure. It is fixed to the sheet metal shell 2 by welding or bolt connection. Alternatively, a cast-in-place support 31 can be used to ensure structural stability. The motor 32 is mounted on the support 31. The motor 32 can be an AC motor or a DC motor, selected according to actual power requirements and usage scenarios. The motor 32 is tightly connected to the support 31 by bolts to ensure the stability of the motor during operation. As the power source of the drive mechanism 3, the motor 32 can provide power for the operation of the entire rotating conveyor rack.

[0036] See Figure 3 , Figure 6 and Figure 7As shown, the transmission mechanism 4 includes an equal-diameter bevel gear set 41, a connecting shaft 42, a worm gear 431 and worm 432 assembly 43, and a connecting rod 44. The equal-diameter bevel gear set 41 is mounted on the output end of the motor 32. The equal-diameter bevel gear set 41 includes a longitudinal equal-diameter bevel gear 411 and a transverse equal-diameter bevel gear 412. The longitudinal equal-diameter bevel gear 411 is mounted on the output end of the motor 32, and the transverse equal-diameter bevel gear 412 meshes with the longitudinal equal-diameter bevel gear 411. They are made of high-strength alloy steel to ensure that they can withstand large torques during transmission. The equal-diameter bevel gear set 41 drives the motor 32 through tooth meshing. The rotational motion of component 2 is reversed. Connecting shaft 42 is mounted on the equal-diameter bevel gear set 41, connecting the equal-diameter bevel gear set 41 and the worm gear 431 / worm 432 assembly 43. The worm gear 431 / worm 432 assembly 43 includes a worm gear 431 mounted on the connecting shaft 42 and a worm 432 meshing with the worm gear 431. The worm 432 is mounted on the connecting rod 44. Brackets for limiting the axial movement of the worm gear 431 are provided on both sides of the worm gear 431, ensuring transmission stability. The worm gear 431 / worm 432 assembly 43 has the function of speed reduction and changing the transmission direction. Connecting rod 44 is connected to auxiliary component 45. Connecting rod 44 can be a cylindrical rod, connected to auxiliary component 45 by key connection or pin connection, etc., to transmit power to auxiliary component 45.

[0037] See Figure 4 As shown, the auxiliary component 45 includes a roller 451 and an auxiliary wheel 452. The roller 451 is rotatably arranged on the sheet metal shell 2 and is mounted on the connecting rod 44. The roller 451 can be a structure with a rubber outer circumference wrapped around a metal hub, which increases the friction with the frame structure 5. Alternatively, it can be an all-metal roller 451, depending on the actual usage requirements. The auxiliary wheel 452 is rotatably arranged on the sheet metal shell 2. The diameter of the auxiliary wheel 452 is smaller than that of the roller 451. The auxiliary wheel 452 can be made of plastic or lightweight alloy to reduce the overall weight. The inner diameter of the frame structure 5 rolls in cooperation with the auxiliary wheel 452, and the outer diameter of the frame structure 5 rolls in cooperation with the roller 451, enabling the frame structure 5 to rotate stably with the support of the roller 451 and the auxiliary wheel 452.

[0038] See Figure 7As shown, the frame structure 5 includes a frame body 51, a load-bearing beam 52, a base plate 53, a positioning block 54, and a load-bearing plate 55. The inner diameter of the frame body 51 is in rolling contact with the auxiliary wheel 452, and the outer diameter of the frame body 51 is in rolling contact with the roller 451. The frame body 51 can be a circular metal frame structure 5, which has high strength and stability. The base plate 53 is installed on the side wall of the frame body 51. The base plate 53 can be made of steel plate and is fixed to the frame body 51 by welding or bolting, etc., to provide support and connection. The load-bearing plate 55 and the base plate 53... The assembly is connected by a baffle 6 mounted on a pad 53. The load-bearing plate 55 and the baffle 6 are connected by a fixing pin 7. The baffle 6 is triangular in shape, which can enhance the stability of the connection. The load-bearing beam 52 is mounted on the load-bearing plate 55. The load-bearing beam 52 can be an I-beam or channel steel structure, which can bear a large weight. The positioning block 54 is mounted on the side of the load-bearing plate 55 away from the load-bearing beam 52. The positioning block 54 is a metal block used to position the engine block and prevent the engine block from shaking during transportation.

[0039] The inspection process for the engine block (some of the components involved are conventionally used in existing technology and are therefore not detailed in the accompanying drawings): After the workpiece is placed on the inspection device, the engine block is placed on the fixture base and initially aligned with the positioning reference. The motor 32 is rotated via remote control, driving the equal-diameter bevel gear set 41. This rotation causes the rotating conveyor rack to rotate around the Z-axis while simultaneously transmitting force to the other two equal-diameter bevel gears. The force is then transmitted to the two pairs of rollers 451 on the corresponding sides via the worm gear 431 and worm 432. By changing the direction of rotation of the worm 432, the rollers 451 on both sides rotate in the same direction. At the same time, a circle is defined by three points, and the circular frame 51 contains ball bearings between it and the rollers 451. The steel balls evenly distributed inside the probe, under the action of the probe spring and push plate, automatically and uniformly contact and center the outer wall of the probe with the inner wall of the detection hole C. The low rolling friction of the steel balls allows the probe to float slightly freely in the longitudinal (X) and transverse (Y) directions within the slide, ensuring that the axis of the probe is automatically aligned with the actual axis of the hole C. The friction of the two wheels causes the circular frame to rotate, achieving rotation around the x and y degrees of freedom. The end face detection slide moves until the hard limit block on it contacts the fixed stop (positioning block 54) on the fixture base and stops. At this time, the precision contact (arc protrusion) of the hook-shaped probe installed at the front end of the end face detection slide is in contact with the key end face of the engine block (such as the engine block mating surface D). A raceway (not shown in the figure) for the sliding of the engine block is installed on the load-bearing beam 52, and a handle (not shown in the figure) for limiting the sliding of the engine block along the raceway is provided on the raceway. The handle is mainly used by the operator to limit the displacement when observing the surface of the engine block. After the inspection is completed, the handle is rotated in the opposite direction. The long shaft reverses direction, and the cam releases the pressure on the movable pressure plate. The movable pressure plate, under the action of the return spring, returns to its original position, pushing the crankshaft bore locating pin downwards and radially retracting via the linkage mechanism, thus releasing the tension positioning of the reference holes A / B. The engine block flows from the horizontal raceway into the rotary conveyor rack. After manually flipping and inspecting each machined surface, the rotary conveyor rack is placed horizontally, and the engine block flows down along the horizontal raceway.

[0040] The implementation principle of a rotary conveyor rack in this application embodiment is as follows: After the motor 32 starts, it drives the longitudinal equal diameter bevel gear 411 to rotate. The longitudinal equal diameter bevel gear 411 meshes with the transverse equal diameter bevel gear 412, transmitting the rotational motion to the connecting shaft 42. The connecting shaft 42 drives the worm gear 431 and worm 432 assembly 43 to move. The worm gear 431 and worm 432 assembly 43 transmits power to the connecting rod 44. The connecting rod 44 drives the roller 451 to rotate. The roller 451 and the auxiliary wheel 452 roll in cooperation with the frame structure 5, causing the frame structure 5 to rotate around the axis of the transmission mechanism 4. The engine cylinder is fixed on the load-bearing beam 52 of the frame structure 5 by a limiting device. The rotation of the frame structure 5 drives the engine cylinder to rotate, which facilitates the inspection of various machined surfaces of the engine cylinder by the staff. This avoids the need for frequent manual removal of the engine cylinder from the raceway, reduces labor intensity, reduces the possibility of damage to the engine cylinder, and improves inspection efficiency and quality.
