Description

Technical Field

[0001] This utility model belongs to the field of wheel processing technology, and in particular relates to a center material transfer and positioning device for processing tubeless lightweight steel wheels. Background Technology

[0002] Lightweight steel wheels are an improvement and innovation of traditional steel wheels in the context of automotive lightweighting, aiming to achieve goals such as weight reduction, performance improvement, and energy consumption reduction. Like ordinary wheels, lightweight steel wheels require positioning. Typically, during wheel manufacturing, the robot lowers the wheel vertically. The wheel's center hole first contacts the mandrel guard, then the positioning mandrel. Once the center hole and positioning mandrel are fully engaged, the robot releases the wheel, completing radial positioning. During the vertical lowering process, the wheel's flange gradually contacts one side of the conical support surface, causing the conical support compression spring to move downwards. After the robot releases the wheel, the spring force causes the wheel to rotate circumferentially, and the conical support surface gradually contacts the other side of the flange, completing circumferential positioning. Simultaneously, the wheel flange surface contacts the upper surface of the base, further confirming the wheel's circumferential position. However, this method still has the following drawbacks in practical use:

[0003] During the processing and positioning of lightweight steel wheels, the equipment needs to first perform radial positioning, then circumferential positioning. Only after positioning is completed can the clamping structure be used for clamping. The center transfer positioning operation requires multiple steps and is relatively complicated.

[0004] Secondly, after the lightweight steel wheels are positioned, they need to be installed and secured. After processing, they need to be loosened from the positioning structure to rotate the processed and unprocessed wheels. The disassembly and assembly of the wheels is not convenient and is quite troublesome to use. Utility Model Content

[0005] The purpose of this utility model is to provide a center transfer positioning device for processing tubeless lightweight steel wheels. By setting a fixed plate, a fixed plate and a limiting chamber, it solves the problems of the large number of steps required for positioning lightweight steel wheels, the complicated operation, and the difficulty in assembling and disassembling the wheels on the positioning device.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a center-mounted material positioning device for processing tubeless lightweight steel wheels, comprising a fixed disc, a fixed plate, and a limiting chamber. The fixed disc has a vertically penetrating opening in its center, and the limiting chamber is movably connected within this opening. The limiting chamber is hollow, and an electric push rod is fixed to the bottom of the limiting chamber. A pushing disc is fixed to the telescopic end of the electric push rod, and movable rods passing through the top of the limiting chamber are fixed in a circular array at the top edge of the fixed disc. A fixed plate is fixed in a circular array at the top edge of the fixed disc, and a movable sleeve is fixed to the top of the fixed plate near the short side of the top edge of the fixed disc. The movable sleeve has a threaded rod rotatably connected to its bottom, and the threaded rod extends out of the top of the movable sleeve. The circumference of the threaded rod is threaded with a movable block, and the movable block is movably connected inside the movable sleeve and extends out of the top of the movable sleeve. The upper edges of both sides of the movable block are fixed with movable sleeves. Each movable sleeve has a movable plate movably connected through it. During operation, the fixed plate is fixed on the fixed plate by the fixed plate. When the fixed plate is working, the movable sleeve and the connecting seat are supported on it. The electric push rod that limits and determines the position of the steel wheels of the car is connected to the electric push rod and the push plate by the limiting chamber. The movable rod fixed to the push plate is connected therein.

[0008] Furthermore, a limiting block one is fixed at the edge of the movable opening at the top of the fixed plate, and a limiting block two is fixed on the periphery of the limiting compartment, which is disposed at the top of the fixed plate and abuts against the limiting block one. The fixed plate restricts and determines the position of the limiting compartment on the fixed plate by the mutual abutment between the limiting block one and the limiting block two on the periphery of the limiting compartment.

[0009] Furthermore, the bottom end of the fixed plate is fixed with columns in a circular array, and the bottom end of the columns is fixed with a chassis. When the fixed plate is working, the chassis is fixed by the columns, and the chassis is fixed to the external drive structure.

[0010] Furthermore, each of the fixed plates has a connecting seat fixed at the edge near the center of the top of the fixed plate, and a limiting strip is fixed at the edge near the movable sleeve. The fixed plate supports the steel wheel above the fixed plate through the cooperation of the connecting seat and the limiting strip.

[0011] Furthermore, a handle is fixed to the top of the threaded rod, a limit plate is fixed to the bottom edge of each movable plate away from the center of the top of the fixed plate, and a pressure block is fixed to the bottom edge of each movable plate near the center of the top of the fixed plate. Rotating the handle causes the threaded rod to rotate, which in turn causes the limit plate and pressure block at the bottom of the movable plate to rise and fall.

[0012] Furthermore, the outer side of the hollow portion inside the restriction chamber is connected to a ring array of mounting bolts. The bottom end of the restriction chamber is supported on the top of the chassis. The mounting bolts are threaded only on the lower part of the screw and are threaded into the chassis, so that the restriction chamber is installed on the fixed plate and the chassis.

[0013] This utility model has the following beneficial effects:

[0014] This invention solves the problem of numerous steps and cumbersome operation required for positioning lightweight steel wheels by setting up a fixed plate and a limiting chamber. When positioning a steel wheel, the electric push rod is activated, driving the movable rod to rise until the top of the push plate contacts the top of the limiting chamber. The wheel hub is then aligned with the center bolt hole of the hub, and the position of the hub center is determined. The hub is supported on the top of the connecting seat and pressed down by the pressure block. Then, the electric push rod is activated to drive the push plate to descend until the movable rod leaves the bolt hole on the hub, completing the positioning work. This reduces the number of steps required for positioning steel wheels and makes the operation more convenient.

[0015] This invention solves the problem of cumbersome assembly and disassembly of lightweight steel wheels on positioning devices by setting a fixed plate and a fixed plate. The rim of the steel wheel is supported on the connecting seat and its position is restricted by the limiting strip on the connecting seat. After completion, push the moving plate to move the pressure block at the bottom of the moving plate above the rim. Then rotate the handle, which drives the threaded rod to rotate. As the threaded rod rotates, it drives the movable block, the moving sleeve, the moving plate, and the pressure block to descend. The pressure block descends and presses down on the rim supported on the connecting seat, supporting the steel wheel above the fixed plate. After the wheel processing is completed, rotate the handle to drive the threaded rod to rotate, which drives the movable block to rise. After the movable block rises, it drives the moving sleeve, the moving plate, the limiting plate, and the pressure block to rise. The pressure block leaves the rim, and then push the moving plate to leave the pressure block above the clamped rim, where it is restricted by the moving sleeve. The steel wheel can then be removed, making the disassembly of the steel wheel on the positioning device much more convenient. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model. Specific Implementation

[0025] Please see Figure 1-3This utility model relates to a center transfer and positioning device for processing tubeless lightweight steel wheels, comprising a fixed plate 1, a fixed plate 2, and a limiting chamber 3. A vertically penetrating opening 101 is provided in the center of the fixed plate 1. The fixed plate 2 is fixed to the fixed plate 1, and the limiting chamber 3 is movably connected to the opening 101. An electric push rod 303 is fixed within the limiting chamber 3. The limiting chamber 3 is hollow, and the electric push rod 303 is fixed to the bottom of the limiting chamber 3. The electric push rod 303 drives the push plate 304 to rise and fall. The push plate 304 is fixed to the telescopic end of the electric push rod 303, and the top of the push plate 304 is fixed with a movable rod 305 that passes through the top of the limiting chamber 3 in a circular array. When the electric push rod 303 is working, it drives the push plate 304 to rise and fall, which in turn drives the movable rod 305 to rise and fall. The movable rod 305 is movably connected to the hole in the center of the steel wheel being processed. The top edge of the fixed plate 1 is fixed with a fixed plate 2 in a circular array. The fixed plate 2 connects the movable sleeve 201 and the connecting seat 20. 9 is fixed on it and connected to the fixed plate 1. A movable sleeve 201 is fixed to the short side of the top edge of the fixed plate 1 near the top edge of the fixed plate 1. The movable sleeve 201 rotatably connects the threaded rod 202 and movably connects the movable block 203 therein. The threaded rod 202 is rotatably connected to the bottom of the movable sleeve 201 and extends out of the top of the movable sleeve 201. The movable block 203 is threadedly connected to the periphery of the threaded rod 202 and is movably connected inside the movable sleeve 201 and extends out of the top of the movable sleeve 201. At the end, as the threaded rod 202 rotates, since the threaded rod 202 is threadedly connected to the movable block 203, the movable block 203 is driven to rise and fall vertically within the movable sleeve 201. Movable sleeves 205 are fixed at the upper edges on both sides of the movable block 203. The movable sleeves 205 on the movable block 203 movably connect the movable plate 206 within them. The movable plate 206 is movably connected through each movable sleeve 205. The movable plate 206 moves between the two rims of the restricted steel wheel through the movable plate 206, restricting the position of the steel wheel above the fixed plate 1.

[0026] Specifically, a limiting block 102 is fixed at the edge of the movable opening 101 at the top of the fixed plate 1, and a limiting block 2 302 is fixed on the periphery of the limiting chamber 3, which is located at the top of the fixed plate 1 and abuts against the limiting block 102. When the limiting chamber 3 is inserted into the movable opening 101 on the fixed plate 1, it is supported on the chassis 104. The limiting chamber 3 is rotated until the limiting block 2 302 on the limiting chamber 3 abuts against the limiting block 102, thus limiting and determining the position of the fixed plate 1 and the limiting chamber 3.

[0027] Furthermore, the bottom end of the fixed plate 1 is fixed with columns 103 in a circular array, and the bottom ends of the columns 103 are all fixed with a chassis 104. The columns 103 at the bottom end of the fixed plate 1 connect the fixed plate 1 and the chassis 104 together. The chassis 104 is fixed on rotating equipment for processing wheels, etc., to cooperate in processing steel wheels.

[0028] Furthermore, each fixed plate 2 has a connecting seat 209 fixed at the edge near the center of the top of the fixed plate 1. A limiting strip 210 is fixed at the edge near the movable sleeve 201 on the top of the connecting seat 209. When the fixed plate 2 is working, the connecting seat 209 supports the bottom rim of the steel wheel that needs to be processed, and the limiting strip 210 restricts the circumference of the rim, determining that the wheel is roughly aligned with the center of the top of the limiting chamber 3.

[0029] Furthermore, a handle 204 is fixed to the top of the threaded rod 202, and a limit plate 207 is fixed to the bottom edge of each movable plate 206 away from the center of the top of the fixed plate 1. A pressure block 208 is fixed to the bottom edge of each movable plate 206 near the center of the top of the fixed plate 1. By rotating the handle 204, the threaded rod 202 is rotated. When the movable plate 206 moves to the limit plate 207 and contacts the movable sleeve 205, the pressure block 208 is positioned above the wheel rim supported on the connecting seat 209. The movable block 203 drives the movable sleeve 205 to descend, so that the pressure block 208 at the bottom of the movable plate 206 presses onto the wheel rim, thus restricting the wheel rim.

[0030] The operation process of this embodiment is as follows: During operation, when a steel wheel requiring center positioning needs to be installed above the fixed plate 1, the position of the steel wheel is first determined by the structure on the limiting chamber 3. The rim of the steel wheel is supported on the connecting seat 209 and its position is limited by the limiting strip 210 on the connecting seat 209. After completion, the moving plate 206 is pushed, and the pressure block 208 at the bottom of the moving plate 206 is pushed to move above the rim. Then, the handle 204 is rotated. The rotation of the handle 204 drives the threaded rod 202 to rotate. During the rotation of the threaded rod 202, the moving block 203, the moving sleeve 205, the moving plate 206, and the... The pressure block 208 descends and presses down on the wheel rim supported by the connecting seat 209, thus supporting the steel wheel above the fixed plate 1. After the wheel processing is completed, the handle 204 is rotated, which drives the threaded rod 202 to rotate and causes the movable block 203 to rise. After the movable block 203 rises, it drives the moving sleeve 205, the moving plate 206, the limiting plate 207, and the pressure block 208 to rise. The pressure block 208 leaves the wheel rim, and then the moving plate 206 is pushed until the pressure block 208 leaves the clamped wheel rim and is fixed in position by the moving sleeve 205. The steel wheel can then be removed to start the next work cycle. Specific Implementation

[0031] Please see Figure 1-5 Based on the first specific embodiment, the outer side of the hollow part inside the restriction chamber 3 is connected to the mounting bolts 301 in a ring array. The bottom end of the restriction chamber 3 is supported at the top of the chassis 104. The mounting bolts 301 are threaded only at the lower part of the screw and are threaded into the chassis 104. The restriction chamber 3 is screwed into the chassis 104 through the mounting bolts 301 inserted therein and after being rotated and tightened, the fixing plate 1 and the restriction chamber 3 are installed together.

[0032] The operation process of this embodiment is as follows: First, determine the number and diameter of the holes in the center of the steel wheel to be processed. Select a suitable number and diameter of movable rods 305 for the limiting chamber 3. Insert the limiting chamber 3 into the movable opening 101 on the fixed plate 1 and support it on the chassis 104. Insert the mounting bolts 301 into the limiting chamber 3, and then pass them through the limiting chamber 3. Rotate the limiting chamber 3 until the second limiting block 302 on the limiting chamber 3 and the first limiting block 102 on the fixed plate 1 abut against each other (position as shown). Figure 1 As shown), rotate the mounting bolt 301 until it is screwed into the chassis 104, and after tightening, the connection between the fixed plate 1 and the limiting chamber 3 is completed. After completion, when the steel wheel needs to be positioned, start the electric push rod 303 to drive the movable rod 305 to rise until the top of the push plate 304 contacts the top of the limiting chamber 3. Then, align the wheel hub offset upwards and the bolt hole at the center of the wheel hub with the movable rod 305 to determine the position of the wheel hub center. The wheel hub is supported on the top of the connecting seat 209 and pressed by the pressure block 208. Then, start the electric push rod 303 to drive the push plate 304 to descend until the movable rod 305 leaves the hole of the mounting bolt 301 on the wheel hub, completing the positioning work.
