Description

Technical Field

[0001] This invention relates to the field of axle manufacturing technology, and in particular to an axle transfer device and transfer method. Background Technology

[0002] The production process of axles involves steps such as heating, forging, and surface finishing. Axles are transported in the axle production workshop via parallel conveyor lines.

[0003] By setting up a transfer trolley on the ground, the traditional method of hoisting and transporting axles by overhead crane can be replaced. The transfer trolley has high transfer efficiency and stability, and can automatically grab axles. Compared with the hoisting and transporting by overhead crane, it can adapt to the entire process of axle production.

[0004] The existing transfer trolley has a telescopic structure installed on its surface. During the transfer of the axle, the telescopic structure needs to be extended into one side of the conveyor line to grip the axle. At the same time, the axle needs to be transferred and transported in a direction perpendicular to the telescopic structure. The axle is heavy, and the small end bearing structure has a small contact area with the axle, which limits the movement speed of the axle in both the horizontal and vertical directions, resulting in low transfer efficiency and poor stability. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides an axle transfer device and transfer method, which can ensure the stability of the axle during the transport process and improve the efficiency and safety of axle transfer.

[0006] To solve the above problems, the technical solution adopted by the present invention is as follows:

[0007] A vehicle axle transfer device includes a conveying body and a telescopic structure installed on the upper end of the conveying body. The telescopic structure includes a first telescopic device slidably connected to the upper end of the conveying body, and a second telescopic device slidably connected inside the first telescopic device. A drive structure is installed on the upper end of the conveying body to control the extension and retraction of the first and second telescopic devices. A bearing component is installed on the top of the second telescopic device to longitudinally limit the axle. A lifting device is installed on the outside of the first telescopic device to laterally limit the axle.

[0008] Preferably, the bearing assembly includes two sets of symmetrically arranged bearing plates, the surface of the bearing rod is provided with limiting grooves, at least two sets of limiting grooves are provided at intervals, and the inner walls on both sides of the limiting grooves are provided with inclined limiting slopes.

[0009] Preferably, the second telescopic device includes a support mounting frame with a guide groove formed at the bottom of the support mounting frame, and the first telescopic device includes a telescopic mounting frame with a guide protrusion fixedly provided near the upper end of the support mounting frame.

[0010] Preferably, a set of guide rails is provided on each side of the telescopic mounting frame, the guide rails have an I-shaped cross section, the load-bearing mounting frame is located between the two sets of guide rails, and a first guide slide group located inside the guide rail is installed on the outer walls of both sides of the load-bearing mounting frame.

[0011] Preferably, the top of the conveying body is recessed to form an installation area, and a second guide slide group is provided on both inner walls of the installation area, the second guide slide group being located outside the guide rail.

[0012] Preferably, the lifting device includes at least two sets of lifting components, the lifting components are located outside the corresponding limiting grooves, the lifting components are fixedly connected to the outer wall of the first telescopic device through a positioning mounting plate, and the surface of the conveying body is fixedly provided with a pumping component that communicates with the lifting components, the pumping component being located on the moving path of the first telescopic device.

[0013] Preferably, the drive structure includes a first drive device installed on the upper end of the conveying body, which controls the linear movement of the first telescopic device. The drive structure also includes a second drive device installed between the first telescopic device and the second telescopic device, which controls the linear movement of the second telescopic device.

[0014] Preferably, the bottom of the conveying body is provided with a traveling device, which includes a steel wheel assembly, a traveling rail corresponding to the steel wheel assembly, and an electrical control device for driving the steel wheel assembly to rotate.

[0015] Preferably, a limiting strip is formed on the outer side of the top of the traveling rail, and a locking protrusion that cooperates with the limiting strip is installed on the side wall of the conveying body.

[0016] A method for transferring axles includes the following steps:

[0017] S1. Control the conveyor body to move to one side of the first conveyor line, extend the first telescopic device and the second telescopic device, and longitudinally limit the axle through the bearing component on the surface of the second telescopic device.

[0018] S2. After the longitudinal limiting of the axle in step S1 is completed, control the first telescopic device and the second telescopic device to retract and reset. After the first telescopic device and the second telescopic device overlap, the lifting device is in the lifting state and performs lateral limiting of the axle from the outside.

[0019] The beneficial effects of this invention are as follows:

[0020] By setting up a load-bearing component, the axle can be longitudinally limited during the longitudinal extension and retraction process, ensuring the stability of the axle's posture during the extension and retraction of the first and second extension devices, thus improving the speed and efficiency of axle transfer and conveying. At the same time, by setting up a lifting device on the outside to laterally limit the axle, the stability of the axle can be ensured during the lateral movement of the conveying body, ensuring the stability of the axle during extension and retraction and transfer, and ensuring the efficiency and safety of the axle transfer process.

Detailed Implementation

[0031] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0032] See attached document Figure 1 - Appendix Figure 9 A vehicle axle transfer device includes a conveying body 100 and a telescopic structure installed on the upper end of the conveying body 100. The telescopic structure is a two-stage telescopic structure that can extend and retract along the direction of the conveying line to complete the loading and unloading of vehicle axles. The telescopic structure includes a first telescopic device 200 slidably connected to the upper end of the conveying body 100, and a second telescopic device 300 slidably connected inside the first telescopic device 200. A drive structure is installed on the upper end of the conveying body 100 to control the extension and retraction of the first telescopic device 200 and the second telescopic device 300.

[0033] The overall structure is electrically controlled and can circulate and extend between the first and second conveyor lines to transport axles. The extension and retraction positions and states of the first extension device 200 and the second extension device 300 are sensed and positioned by external sensors, realizing automatic transfer and conveying of axles and improving the efficiency of axle forging production.

[0034] A bearing assembly 320 is installed on the top of the second telescopic device 300, which longitudinally limits the axle. A lifting device 250 is installed on the outside of the first telescopic device 200, which laterally limits the axle. Here, the longitudinal direction refers to the direction of extension and retraction of the first telescopic device 200 and the second telescopic device 300, and the lateral direction refers to the direction of movement of the conveyor body 100. The lateral and longitudinal directions are perpendicular to each other. By limiting the longitudinal direction of the axle, the stability of the axle's longitudinal movement can be ensured during the extension and retraction of the first telescopic device 200 and the second telescopic device 300. After the first telescopic device 200 and the second telescopic device 300 have retracted, the lateral direction of the axle is limited, which can ensure the stability of the axle's lateral movement.

[0035] In summary, the above design ensures the stability of the axle during lateral and longitudinal transport. Simultaneously, the lifting device 250, after the first telescopic device 200 and the second telescopic device 300 retract and overlap, lifts to support and limit the outer side of the axle. During the extension of the first telescopic device 200 and the second telescopic device 300, the lifting device 250 is in a retracted and hidden state, thus avoiding interference with the movement of the first telescopic device 200 and the second telescopic device 300 along the transport line.

[0036] Please refer to the appendix for details. Figure 8 The bearing assembly 320 includes two sets of symmetrically arranged bearing plates. The surface of the bearing rod has a limiting groove 321. At least two sets of limiting grooves 321 are spaced apart. The inner walls on both sides of the limiting groove 321 have inclined limiting slopes. The cross-section of the limiting groove 321 is an inverted trapezoid, which can accommodate and limit axles of different sizes. The symmetrically arranged bearing plates can support and limit the axles from both sides at the bottom, ensuring the stability of the overall structure. At the same time, the setting of at least two sets of limiting grooves 321 can transfer at least two axles at a time, improving the efficiency of axle transfer and transportation.

[0037] The second telescopic device 300 includes a support mounting frame 310, with a guide groove 330 formed at the bottom of the support mounting frame 310. The first telescopic device 200 includes a telescopic mounting frame 210, with a guide protrusion 230 fixedly provided near the upper end of the support mounting frame 310. The outer dimensions of the guide protrusion 230 are the same as the inner wall dimensions of the guide groove 330. When the first telescopic device 200 and the second telescopic device 300 are in the combined state, the guide protrusion 230 slides within the guide groove 330, which can limit the position of the upper second telescopic device 300 from the middle position, ensuring the stability of the second telescopic device 300 during horizontal extension.

[0038] A set of guide rails 220 are respectively provided on both sides of the telescopic mounting frame 210. The guide rails 220 have an I-shaped cross section. The bearing mounting frame 310 is located between the two sets of guide rails 220. The outer walls of both sides of the bearing mounting frame 310 are equipped with first guide slides 311 located in the guide rails 220. The size of the second telescopic device 300 is smaller than that of the first telescopic device 200, so that the second telescopic device 300 can enter the conveyor line at the end to complete the up and down transportation of the axle. At the same time, by setting the I-shaped guide rails 220 on both sides, the second telescopic device 300 can be limited again from both sides, further ensuring the stability of the overall horizontal movement of the second telescopic device 300. The above design can effectively distribute the mass of the second telescopic device 300 and the axle on the surface of the second telescopic device 300. It can cooperate with the combination of the guide groove 330 and the guide protrusion 230 to increase the maximum load of the second telescopic device 300 and ensure the stability of the overall structure.

[0039] An installation area 110 is formed by recessing the top of the conveying body 100. A second guide slide group 111 is provided on both inner walls of the installation area 110. The second guide slide group 111 is located outside the guide rail 220. By setting the second guide slide group 111, it can be located in the groove outside the guide rail 220 to guide the first telescopic device 200 as a whole, ensuring the stability of the first telescopic device 200 during the extension process. The second guide slide group 111 extends along the sliding direction of the first telescopic device 200 and is set in multiple groups, which can extend the extension distance of the first telescopic device 200 and ensure the stability of the overall structure.

[0040] The second guide slide group 111 and the first guide slide group 311 both include a horizontally arranged first guide wheel and a vertically arranged second guide wheel, which can ensure the stability of the horizontal movement of the first telescopic device 200 and the second telescopic device 300 from two directions.

[0041] Please refer to the appendix for details. Figure 9The lifting device 250 includes at least two sets of lifting components. The lifting components are located outside the corresponding limiting grooves 321. The lifting components are fixedly connected to the outer wall of the first telescopic device 200 through the positioning mounting plate 240. The surface of the conveying body 100 is fixedly provided with a pumping component 600 that communicates with the lifting components. The pumping component 600 is located on the moving path of the first telescopic device 200. The number of lifting components corresponds to the limiting grooves 321, which can press against the axle. At the same time, the lifting components have built-in elastic components. The lifting components are normally in a contracted state. When the first telescopic device 200 and the second telescopic device 300 are contracted and reset, they can squeeze the pumping component 600, so that the pumping component 600 is in a contracted state, and the lifting oil in the pumping component 600 is pumped into the lifting component, controlling the lifting component to be in a lifting state, pressing against the outside of the axle above, so as to ensure the stability of the axle moving between different conveyor lines.

[0042] Through the above design, after the first telescopic device 200 retracts to its initial position, the lifting assembly can be controlled to be in a lifting posture to ensure the stability of the axle transport. The overall lifting process is carried out automatically during the reset of the first telescopic device 200, without the need for external electrical control components, reducing the number of electrical components in the device. It can withstand the high temperature around the forged axle and can perform long-term stable lifting control. The end of the lifting assembly can be equipped with a position control plate that is offset along the horizontal direction, so that the axle can continue to be vertically lifted during the horizontal movement of the axle, ensuring the stability of the axle when it retracts to the end.

[0043] It should also be noted that the aforementioned lifting device 250 can be installed on one side, positioned behind the moving conveyor body 100, as shown in the attached diagram. Figure 2 When the conveying body 100 moves to the left, the lifting device 250 is set on the right side, which can effectively overcome the axle inertia caused by the sudden start of the conveying body 100 and ensure the overall lateral stability of the axle during the initial acceleration of the conveying body 100.

[0044] Please refer to the appendix for details. Figure 6 Appendix Figure 7 The drive structure includes a first drive device 400 installed on the upper end of the conveying body 100, which controls the linear movement of the first telescopic device 200. The drive structure also includes a second drive device 500 installed between the first telescopic device 200 and the second telescopic device 300, which controls the linear movement of the second telescopic device 300.

[0045] The first drive device 400 here can be controlled by a lead screw structure, including a drive motor 430, a position control lead screw 410, and a transmission component 420 that transmits power between the two. A lead screw seat is fixedly installed at the bottom of the first telescopic device 200. During the rotation of the position control lead screw 410, the telescopic movement of the first telescopic device 200 can be controlled. The telescopic control by the lead screw structure has a long overall stroke, accurate and stable control position, and can ensure the longitudinal stability of the axle and accurate transfer and conveying.

[0046] The second drive device 500 here can be selected as a drive chain 510, a first sprocket 520, and a second sprocket 530 working together. The first sprocket 520 and the second sprocket 530 are installed on the inner wall of the conveying body 100. The first end of the drive chain 510 is connected to the inside of the first telescopic device 200, and the second end of the drive chain 510 is connected to the inside of the second telescopic device 300. When the first drive device 400 controls the first telescopic device 200 to move outward, the second telescopic device 300 can be pulled outward by the drive chain 510, which bypasses the first sprocket 520 and the second sprocket 530. At the same time, an elastic component is provided between the first telescopic device 200 and the second telescopic device 300, so that the overall structure has a tendency to contract. When the first drive device 400 controls the first telescopic device 200 to contract, the second telescopic device 300 drives the drive chain 510 to reset under the action of elasticity, and the overall structure returns to its initial state, realizing automatic telescopic control.

[0047] The second telescopic device 300 is controlled to extend and retract using the above structure. The overall structure can be hidden between the first telescopic device 200 and the second telescopic device 300, reducing the volume of the drive structure. At the same time, the overall structure uses the power of the first drive device 400 to drive the second telescopic device 300, improving the coordination of the extension and retraction of the first telescopic device 200 and the second telescopic device 300, and facilitating the control of extension and retraction. Similarly, the overall structure can withstand the high temperature of the forged axle, ensuring the stability of the drive control.

[0048] A traveling device is provided at the bottom of the conveying body 100. The traveling device includes a steel wheel assembly 120, a traveling rail 130 corresponding to the steel wheel assembly 120, and an electronic control device 140 for driving the rotation of the steel wheel assembly 120. The electronic control device 140 controls the rotation of the steel wheel assembly 120, enabling it to move linearly along the surface of the traveling rail 130. The combination of the traveling rail 130 and the steel wheel assembly 120 ensures the accuracy of the moving direction and the stability of the conveying body 100. Simultaneously, a limiting strip is formed protruding from the top outer side of the traveling rail 130. The side wall of the conveyor body 100 is equipped with a locking protrusion that cooperates with the limiting strip. During the movement of the conveyor body 100, the locking protrusion can lock the limiting strip to ensure the stability of the conveyor body 100 during the extension of the first telescopic device 200 and the second telescopic device 300. At the same time, the locking protrusion is designed to be concave and located at the bottom of the side of the conveyor body 100 away from the second telescopic device 300. By setting the locking protrusion to cooperate with the limiting strip, it can overcome the gravity of the second telescopic device 300 during the extension of the conveyor axle and ensure the stability of the overall movement.

[0049] A method for transferring axles, using the aforementioned transfer device, includes the following steps:

[0050] S1. Control the conveying body 100 to move to one side of the first conveying line, extend the first telescopic device 200 and the second telescopic device 300, and use the bearing component 320 on the surface of the second telescopic device 300 to longitudinally limit the axle. During the extension and retraction of the first telescopic device 200 and the second telescopic device 300, the axle can be longitudinally limited to ensure the stability of the axle during this process.

[0051] S2. After the longitudinal limiting of the axle in step S1 is completed, control the first telescopic device 200 and the second telescopic device 300 to retract and reset. After the first telescopic device 200 and the second telescopic device 300 overlap, the lifting device 250 is in the lifting state and performs lateral limiting of the axle from the outside. After the first telescopic device 200 and the second telescopic device 300 retract and reset to the initial position, the outer lifting device 250 can lift and support the axle from the bottom to ensure the stability of the axle during lateral movement.

[0052] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
