Description

Technical Field

[0001] This invention relates to the field of parts blanking technology, and more specifically, to a blanking device for processing gas turbine parts. Background Technology

[0002] In modern industry, gas turbines, with their significant advantages such as high efficiency and high power density, are widely used in many key areas such as power generation, aerospace propulsion, and industrial drive. The machining precision and quality requirements for gas turbine components are extremely high; even minor defects can seriously affect the performance and reliability of the entire gas turbine.

[0003] In the manufacturing process of gas turbine components, the material unloading stage is a crucial initial step. The unloading device needs to accurately transport raw materials or semi-finished products to the designated processing position to ensure the smooth progress of subsequent processing steps.

[0004] During the assembly of a gas turbine, bearings of different sizes and weights are required. When the weight of the bearings increases, the conveyor belt will sink under the influence of gravity, causing the conveyor belt to be lower than the material feeding plate. Due to these positional changes, the position of the material feeding plate needs to be readjusted every time a bearing is transferred, increasing the complexity of the operation and reducing the efficiency of transfer and assembly. Summary of the Invention

[0005] This invention provides a feeding device for processing gas turbine parts. By using an expansion plate to expand the conveyor belt and tightening it at the feeding point, the invention solves the problem mentioned in the background art, namely, that the position of the feeding plate needs to be readjusted every time a bearing transfer operation is performed.

[0006] To achieve the above objectives, a material unloading device for processing gas turbine components includes a conveyor belt, a drive wheel, and limiting plates located on both sides above the conveyor belt to restrict bearing offset. A material unloading point is formed at the end of the conveyor belt, and a transfer point is formed on a bearing plate that is longitudinally flush with the material unloading point. There is a certain distance between the material unloading point and the transfer point. The end of the bearing plate is close to the conveyor belt. A material-pushing plate and an expansion mechanism are provided on one side of the bearing plate. The expansion mechanism is arranged in an array inside the drive wheel. During the transfer phase, the expansion mechanism causes the conveyor belt to tighten by expanding outward, so as to axially abut against the inner wall and side wall of the conveyor belt and lift the bearing located at the material unloading point to form a misaligned state with the material-pushing plate, thereby realizing the transfer of the bearing at the material unloading point.

[0007] The feeding plate is equipped with a material receiving groove for accommodating the bearings at the feeding point and the transfer point respectively. Under normal conditions, the height of the bearing plate is slightly lower than that of the conveyor belt, and the material receiving groove at the transfer point is staggered with the bearing at that point.

[0008] A power unit is provided on one side of the material feeding plate. The power unit includes a support plate located at the bottom of the material feeding plate and movably connected to the material feeding plate in the lateral direction. A lateral cylinder is fixedly installed on the support plate. The lateral cylinder is responsible for pushing the material feeding plate to move laterally. A longitudinal cylinder is connected in the longitudinal direction of the support plate. The longitudinal cylinder is responsible for pushing the support plate to move longitudinally.

[0009] When the weight of the bearing at the feeding point increases, the conveyor belt at the feeding point sinks, causing the bearing to be lower than the material receiving trough at the feeding point in the horizontal direction.

[0010] Several receiving grooves are provided on the outer edge of the drive wheel.

[0011] The expansion mechanism includes an expansion plate located in the receiving groove and a top rod fixed to the expansion plate. The expansion plate extends longitudinally to fit against the side wall of the drive wheel to cover the upper drive wheel. The top rod passes through the internal cavity of the drive wheel and is slidably connected to the drive wheel.

[0012] An extension rod fixed to the support plate is provided inside the cavity of the drive wheel. The extension rod passes through one side of the rotating shaft and is rotatably connected to the rotating shaft. A cone is fixedly provided at the end of the extension rod, and the cone has an inclined surface that fits against the top rod.

[0013] The material trough is larger than the bearing so that there is reserved space between the inner wall of the material trough and the bearing during the transfer process.

[0014] The wide end of the conveyor belt is smaller than the distance between the two side walls of the drive wheel, so that the side of the conveyor belt and the side wall of the drive wheel form a reserved gap.

[0015] An air cushion is fitted between the drive wheel and the conveyor belt. The air cushion covers several expansion plates. When the expansion plates apply pressure to the air cushion, the expansion plates drive the air cushion to push the conveyor belt out and tighten it, so as to lift the bearing at the unloading point into the material receiving trough. The two ends of the air cushion overflow into the reserved gap to provide longitudinal support for the two sides of the conveyor belt.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] 1. In the unloading device for processing gas turbine parts, when the feeding plate reaches the preset point, the expansion plate expands the conveyor belt, and the conveyor belt tightens at the unloading point. The conveyor belt lifts the bearing upward into the receiving trough, so that it is misaligned with the receiving trough, ensuring the accurate positioning of the bearing during the transfer process and improving the transfer efficiency.

[0018] 2. In the unloading device for processing gas turbine parts, the air cushion is bound together by the expansion plate and the conveyor belt, causing the air cushion to overflow into the reserved gap and laterally squeeze the side wall of the drive wheel to increase the friction between it and the conveyor belt, thereby ensuring the stable transport of the bearing.

[0030] The technical solutions of this invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0031] To address the issue of conveyor belt sagging, which prevents bearings from being properly rotated, this invention discloses a feeding device for machining gas turbine components. (Refer to...) Figure 1As shown, the system includes a conveyor belt 100, a drive wheel 101, and limiting plates 102 located on both sides above the conveyor belt 100 to limit bearing offset. A discharge point is formed at the end of the conveyor belt 100, and a transfer point is formed on a support plate 103 that is longitudinally flush with the discharge point. There is a certain distance between the discharge point and the transfer point. The end of the support plate 103 is close to the conveyor belt 100. A material-pulling plate 110 and an outward expansion mechanism 130 are provided on one side of the support plate 103. The outward expansion mechanism 130 is arranged in an array inside the drive wheel 101. During the transfer phase, the outward expansion mechanism 130 causes the conveyor belt 100 to tighten by outward expansion, so as to axially abut against the inner wall and side wall of the conveyor belt 100, and lift the bearing at the discharge point to a misaligned state with the material-pulling plate 110, thereby realizing the transfer of the bearing at the discharge point. The specific process is as follows:

[0032] First, when transferring bearings, the bearing to be transferred is placed at one end of the conveyor belt 100, and the bearing is then transported via the conveyor belt 100. The bearing status on the conveyor belt 100 is referenced. Figure 1 As shown, when the bearing is conveyed between the two limiting plates 102, the limiting plates 102 guide the bearing, restrict the bearing offset, and enable the bearing to be stably conveyed to the material point. During this process, a rotating shaft 105 is coaxially connected to both ends of the drive wheel 101. A support block 104 is slidably connected on the rotating shaft 105. The support block 104 is used to support the rotating shaft 105. The rotating shaft 105 is driven by a motor. In this way, the drive wheel 101 drives the drive wheel 101 to transport the bearing to the material point for subsequent transfer.

[0033] Then, the feeding plate 110 has a receiving groove 111 for accommodating the bearing at the feeding point and the bearing at the transfer point. Under normal conditions, the bearing plate 103 is slightly lower than the conveyor belt 100. The normal conditions referred to here are the state where no bearing is placed on the conveyor belt 100, and the receiving groove 111 at the transfer point is misaligned with the bearing at that position. When the bearing is transferred, a power unit is provided on one side of the feeding plate 110. The power unit includes a support plate 122 located at the bottom of the feeding plate 110 and movably connected to the feeding plate 110 in the lateral direction. A lateral cylinder 120 is fixedly provided on the support plate 122. The lateral cylinder 120 is responsible for pushing the feeding plate 110 to move laterally. A longitudinal cylinder 121 is connected in the longitudinal direction of the support plate 122. The longitudinal cylinder 121 is responsible for pushing the support plate 122 to move longitudinally.

[0034] It should be noted that during the operation, the longitudinal cylinder 121 is in a fixed state, and the material feeding plate 110 moves laterally under the action of the transverse cylinder 120, so that after the transfer, the material receiving groove 111 moves away from the bearing, and the bearing is disengaged from the material receiving groove 111. Then, under the action of the longitudinal cylinder 121, the support plate 122 and the material feeding plate 110 are pushed to move longitudinally, and the material receiving groove 111 moves to correspond to the bearing in the transverse direction. Then, the material receiving groove 111 receives the bearing and performs a second transfer, and so on.

[0035] In this way, the bearings at the feeding point and transfer point can be transferred by the longitudinal movement of the feeding plate 110, so that the bearings at the feeding point are transported to the bearing plate 103. The bearings on the bearing plate 103 are transported in the longitudinal direction for later installation and use.

[0036] Furthermore, since bearings of different sizes are required during the assembly of gas turbine components, their weights also vary. When the weight of the bearing at the unloading point increases, the conveyor belt 100 at the unloading point sinks, causing the bearing to be horizontally lower than the material receiving trough 111 at the unloading point. Figure 2 In the state shown, when the material feeding plate 110 moves longitudinally, the bearing at the feeding point is lower than the material feeding plate 110, while the bearing at the transfer point is located in the material receiving trough 111 and is misaligned with the material receiving trough 111. Therefore, the bearing at the transfer point can only be moved, but the bearing at the material receiving trough 111 cannot be transferred.

[0037] Therefore, in combination Figure 3 , Figure 4 As shown, a plurality of receiving grooves are provided on the outer edge of the drive wheel 101; the expansion mechanism 130 includes an expansion plate 131 located in the receiving groove and a top rod 132 fixed to the expansion plate 131. The expansion plate 131 extends longitudinally to fit against the side wall of the drive wheel 101 to cover the upper drive wheel 101. The top rod 132 passes through the internal cavity of the drive wheel 101 and is slidably connected to the drive wheel 101. On the other hand, an extension rod 123 fixed to the support plate 122 is provided in the cavity of the drive wheel 101. The extension rod 123 passes through one side of the rotating shaft 105 and is rotatably connected to the rotating shaft 105. A cone 124 is fixedly provided at the end of the extension rod 123. The cone 124 has an inclined surface that fits against the top rod 132.

[0038] Working principle: First, since the extension rod 123 is connected to the support plate 122, and the extension rod 123 passes through the rotating shaft 105, when the rotating shaft 105 drives the drive wheel 101 to rotate, the extension rod 123 remains in a fixed position, while the rotating shaft 105 rotates around its own axis. During the transfer phase, the extension rod 123 moves longitudinally. (Refer to...) Figure 3As shown by the middle arrow, the extension rod 123 drives the cone 124 to move longitudinally. At this time, when the material receiving trough 111 at the unloading point moves above the bearing, the material receiving trough 111 corresponds to the circumferential bearing. At this time, the bearing is lower than the material receiving trough 111, and the two are in a non-misaligned state. As the cone 124 presses against the top rod 132, the top rod 132 transmits power to the expansion plate 131. Several expansion plates 131 expand outward to support the conveyor belt 100, so that the conveyor belt 100 changes from a loose state to a taut state. After the conveyor belt 100 is taut, it raises the bearing at the unloading point, so that the bearing is located in the material receiving trough 111 and forms a misalignment with it, preventing the bearing from being missed and affecting the transfer efficiency.

[0039] It should be understood that the size of the material receiving trough 111 is larger than that of the bearing so that there is a reserved space between the inner wall of the material receiving trough 111 and the bearing during the transfer process; that is, during the tensioning process of the conveyor belt 100, the contact time between the inner wall of the material receiving trough 111 and the bearing can be extended, leaving time for the bearing to move upward. When the conveyor belt 100 lifts the bearing to a state of misalignment with the material receiving trough 111, the bearing is in a state of close contact with the inner wall of the material receiving trough 111.

[0040] In summary, when the feeding plate 110 reaches the preset point, the expansion plate 131 expands the conveyor belt 100, and the conveyor belt 100 tightens at the unloading point. The conveyor belt 100 lifts the bearing upward into the receiving trough 111, so that it is misaligned with the receiving trough 111, ensuring the accurate positioning of the bearing during the transfer process and improving the transfer efficiency.

[0041] Figure 4 The diagram shows the direction in which the cone 124 pushes out the extension rod 123. When the conveyor belt 100 is pushed out, it expands outwards, supporting and taut the conveyor belt 100, so that the material receiving trough 111 at the discharge point is in a position... Figure 5 The state shown above is the first embodiment of the present invention. The following is in conjunction with... Figure 3 , Figure 4 , Figure 6 As shown, a second embodiment of the present invention is illustrated, which is detailed below:

[0042] First, the wide end of the conveyor belt 100 is smaller than the distance between the two side walls of the drive wheel 101, so that the side of the conveyor belt 100 and the side wall of the drive wheel 101 form a reserved gap 106.

[0043] Secondly, an air cushion 133 is fitted between the drive wheel 101 and the conveyor belt 100. The air cushion 133 covers several expansion plates 131. When the expansion plates 131 apply pressure to the air cushion 133, the expansion plates 131 drive the air cushion 133 to push out and tighten the conveyor belt 100, so as to lift the bearing at the unloading point into the receiving trough 111. At the same time, the two ends of the air cushion 133 overflow into the reserved gap 106 to provide longitudinal support for both sides of the conveyor belt 100. Therefore, when the expansion plates 131 transmit the force to the air cushion 133, the air cushion 133 applies pressure to the feeding plate 110 through expansion, so as to increase the friction between the air cushion 133 and the conveyor belt 100. At the same time, the expanded conveyor belt 100 is taut, so that the conveyor belt 100 at the unloading point lifts the bearing upward into the receiving trough 111, which facilitates the transfer by the feeding plate 110.

[0044] Meanwhile, constrained by the conveyor belt 100, the air cushion 133 overflows into the reserved gap 106 on both sides. At this time, the air cushion 133 located in the reserved gap 106 is supported by the side wall of the drive wheel 101. The reserved gap 106 applies pressure to the side of the conveyor belt 100, increasing the friction between the reserved gap 106 and the side wall of the conveyor belt 100. After the bearing at the material point is transferred to the bearing plate 103, the bearing on the conveyor belt 100 is transferred to the material point again. By increasing friction, the conveyor belt 100 can be prevented from sliding or misaligning during the force or operation, further improving the overall stability of the device and ensuring the smooth operation of the bearing transfer process.

[0045] In other words, the expansion plate 131 and the conveyor belt 100 together bind the air cushion 133, causing the air cushion 133 to overflow into the reserved gap 106 and laterally squeeze the side wall of the drive wheel 101 to increase the friction between it and the conveyor belt 100, thereby ensuring the stable delivery of the bearing.

[0046] Furthermore, refer to Figure 4 As shown, at the point where the expansion plate 131 and the air cushion 133 fit together, the expansion plate 131 is also provided with anti-slip grooves to increase the friction between it and the air cushion 133 and prevent slippage during rotation.

[0047] After the bearing at the material feeding point is transferred to the bearing plate 103, the bearing on the conveyor belt 100 can be quickly and smoothly transferred to the material feeding point again. Then, the cone 124 is reset, and the above process is repeated.

[0048] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
