Description

Technical Field

[0001] This utility model relates to the field of wheel hub end clamps, and in particular to a wheel hub end face milling clamp. Background Technology

[0002] The wheel hub end face milling fixture is a high-precision positioning and clamping device specifically designed for automotive wheel hub machining. It typically employs hydraulic or mechanical clamping methods, using a central positioning shaft and end face pressure plate to achieve radial positioning and axial clamping of the wheel hub. The fixture base features a high-strength cast iron structure to ensure rigidity and integrates adjustable positioning pins to accommodate different wheel hub sizes. Some fixtures are equipped with a rotary indexing function to achieve multi-angle milling. Key contact surfaces are hardened to improve wear resistance. Additionally, chip removal grooves and coolant channels are designed to ensure stability and smooth chip removal during machining, meeting the machining requirements for the flatness of the wheel hub end face.

[0003] The rigid structure of common wheel hub end milling fixtures makes it impossible to quickly replace or adjust the gripper components. They can only be adapted to wheel hubs of fixed specifications. When switching to different shapes, the fixture must be completely disassembled and reinstalled, which is time-consuming and affects production efficiency. Furthermore, repeated disassembly and reassembly can cause wear on the positioning reference, reduce machining accuracy, and increase maintenance costs.

[0004] Therefore, given the rigid structure of the aforementioned common wheel hub end face milling fixtures, which cannot quickly replace or adjust the gripper components, can only adapt to wheel hubs of fixed specifications, and require complete disassembly and reinstallation of the fixture when switching to different shapes, resulting in time-consuming processes and significant impacts on production efficiency, a new wheel hub end face milling fixture can be designed. Utility Model Content

[0005] To overcome the problems of the rigid structure of common wheel hub end milling fixtures, which cannot quickly replace or adjust the gripper components, can only adapt to wheel hubs of fixed specifications, and require complete disassembly and reinstallation of the fixture when switching to different shapes, which is time-consuming and greatly affects production efficiency.

[0006] The technical solution of this utility model is as follows: a wheel hub end face milling fixture, including an operating table; and a clamping plate. Four support plates are provided on the upper end of the operating table. The clamping plate is movably connected to the top of the support plates. A first insert block is fixedly connected to the top of the support plates. A fixing rod is fixedly connected to the outer surface of the support plates. A moving block is slidably connected to the outer surface of the fixing rod. A spring is fixedly connected between the moving block and the support plates. An electric cylinder is fixedly connected to the top of the moving block. A second insert block is fixedly connected to the output end of the electric cylinder. The electric cylinder is used to drive the second insert block to move up and down. The second insert block is movably connected to the clamping plate. Two locking blocks are fixedly connected to the end of the support plate near the moving block. Two protrusions are provided on the outer surface of the moving block. The protrusions are movably connected to the locking blocks.

[0007] Preferably, after the electric cylinder drives the second insert block to move upward and disengage from the clamping plate, the moving block is manually pulled to separate the protrusion from the locking block, and slides along the fixed rod to remove the old clamping plate from the first insert block and the support plate. After replacing the new clamping plate, the moving block automatically resets under the action of the spring to relock the locking block and the protrusion. Then, the electric cylinder drives the second insert block to move downward and insert into the clamping plate to complete the fixation. This realizes the rapid switching of clamping plates for different shaped wheel hubs, avoids the time-consuming problem of reinstallation after complete disassembly of traditional clamps, and significantly improves production efficiency.

[0008] Preferably, silicone grippers are fixedly connected to the outer surface of the clamping plate, and a fixing frame is fixedly connected to the bottom of the operating table.

[0009] Preferably, two electric cylinders are fixedly connected to the top of the fixed frame, and a connecting block is fixedly connected to the output end of the electric cylinder. The electric cylinder is used to drive the connecting block to move back and forth.

[0010] Preferably, the upper end of the operating table is provided with four sliding grooves, and a slider is slidably connected to the inner side of the sliding groove.

[0011] Preferably, the connecting block is fixedly connected to the slider, and the bottom of the slider is rotatably connected to a connecting rod.

[0012] Preferably, a square plate is rotatably connected to the bottom of the connecting rod, and a positioning column is fixedly connected to the top of the operating table.

[0013] Preferably, a central rod is fixedly connected to the bottom of the operating table, and the central rod is slidably connected to the square plate.

[0014] The beneficial effects of this utility model are:

[0015] After the electric cylinder drives the second insert block to move upward and detach from the clamping plate, the manual pulling of the moving block separates the protrusion from the locking block and slides along the fixed rod to remove the old clamping plate from the first insert block and the support plate. After replacing the new clamping plate, the moving block automatically resets under the action of the spring, so that the locking block and the protrusion are locked again. Then the electric cylinder drives the second insert block to move downward and insert into the clamping plate to complete the fixation. This realizes the rapid switching of clamping plates for different shaped wheel hubs, avoids the time-consuming problem of reassembly after complete disassembly of traditional clamps, and significantly improves production efficiency.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figures 1-5 This utility model provides an embodiment: a wheel hub end face milling fixture includes an operating table 1; it also includes a clamping plate 3. Four support plates 2 are provided on the upper end of the operating table 1. The clamping plate 3 is movably connected to the top of the support plates 2. A first insert block 4 is fixedly connected to the top of the support plates 2. A fixing rod 8 is fixedly connected to the outer surface of the support plates 2. A moving block 6 is slidably connected to the outer surface of the fixing rod 8. A spring 9 is fixedly connected between the moving block 6 and the support plate 2. An electric cylinder 7 is fixedly connected to the top of the moving block 6. A second insert block 5 is fixedly connected to the output end of the electric cylinder 7. The electric cylinder is used to drive the second insert block 5 to move up and down. The second insert block 5 is movably connected to the clamping plate 3. The end of the support plate 2 near the moving block 6... The fixed connection has two locking blocks 10, and the outer surface of the movable block 6 is provided with two protrusions 11. The protrusions 11 are movably connected to the locking blocks 10. After the electric cylinder 7 drives the insert block 5 to move upward and separate from the clamping plate 3, the movable block 6 is manually pulled to separate the protrusions 11 from the locking blocks 10, and slides along the fixed rod 8 to pull the old clamping plate 3 out from the insert block 4 and the support plate 2. After replacing the new clamping plate 3, the movable block 6 automatically resets under the action of the spring 9 to relock the locking blocks 10 and the protrusions 11. Then the electric cylinder 7 drives the insert block 5 to move downward and insert into the clamping plate 3 to complete the fixation. This realizes the rapid switching of clamping plates 3 of different shaped wheel hubs, avoids the time-consuming problem of reinstallation that requires complete disassembly of traditional clamps, and significantly improves production efficiency.

[0024] Please see Figures 3-5In this embodiment, a silicone gripper 12 is fixedly connected to the outer surface of the clamping plate 3, and a fixing frame 13 is fixedly connected to the bottom of the operating table 1. The silicone gripper 12 on the clamping plate 3 increases the friction between it and the wheel hub. Two electric cylinders 14 are fixedly connected to the top of the fixing frame 13. A connecting block 15 is fixedly connected to the output end of the electric cylinder 14. The electric cylinder 14 is used to drive the connecting block 15 to move back and forth. The electric cylinder 14 drives the connecting block 15 to move backward. Four sliding grooves 19 are opened at the upper end of the operating table 1. A slider 16 is slidably connected to the inner side of the sliding groove 19. The connecting block 15 drives the slider 16 to slide in the sliding groove 19 towards the wheel hub.

[0025] Please see Figures 2-5 In this embodiment, the connecting block 15 is fixedly connected to the slider 16. The bottom of the slider 16 is rotatably connected to the connecting rod 17. When the slider 16 slides, the connecting rod 17 rotates on the slider 16. The other end of the connecting rod 17 drives the square plate 18 to rotate. The bottom of the connecting rod 17 is rotatably connected to the square plate 18. The top of the operating table 1 is fixedly connected to the positioning post 20. When the square plate 18 rotates, it drives the three corresponding sliders 16 to slide in the slide groove 19 through the other three connecting rods 17. The positioning post 20 on the operating table 1 can help determine the center position, making it convenient to place the hub in a suitable position. The bottom of the operating table 1 is fixedly connected to the center rod 21. The center rod 21 is slidably connected to the square plate 18. The center rod 21 can drive the operating table 1 to rotate through the external machinery.

[0026] During operation, if it is necessary to replace the clamping plate 3 to adapt to a wheel hub with a special shape, the electric cylinder 7 drives the insert block 5 to move upward out of the clamping plate 3, pulling the moving block 6 to separate the protrusion 11 from the locking block 10. Then, the moving block 6 slides on the fixing rod 8, pulling the clamping plate 3 upward away from the insert block 4 and the support plate. A suitable new clamping plate 3 is then inserted into the insert block 4. Then, the moving block 6 returns to its original position under the action of the spring 9, simultaneously locking the locking block 10 into the protrusion 11. Then, the electric cylinder 7 drives the insert block 5 to move downward and insert it into the clamping plate 3, fixing the clamping plate 3 onto the support plate 2. The wheel hub is then placed on the operating table 1. The positioning pin 20 on the operating table 1 can help determine the center position for easy positioning. Place the wheel hub in the appropriate position, and then the electric cylinder 14 drives the connecting block 15 to move backward. The connecting block 15 drives the slider 16 to slide in the groove 19 towards the wheel hub. When the slider 16 slides, the moving connecting rod 17 rotates on the slider 16. The other end of the connecting rod 17 drives the square plate 18 to rotate. When the square plate 18 rotates, it drives the three corresponding sliders 16 to slide in the groove 19 through the other three connecting rods 17. Then the slider 16 drives the clamping plate 3 to move and firmly fix the wheel hub on the operating table 1. The silicone gripping block 12 on the clamping plate 3 increases the friction between it and the wheel hub. The center rod 21 can drive the operating table 1 to rotate through the external machinery.

[0027] Through the above steps, if it is necessary to replace the clamping plate 3 to adapt to a wheel hub with a special shape, the electric cylinder 7 drives the insert block 5 to move upward out of the clamping plate 3, pulls the moving block 6 to separate the protrusion 11 from the locking block 10, and then the moving block 6 slides on the fixed rod 8 to pull the clamping plate 3 upward away from the insert block 4 and the support plate. A suitable new clamping plate 3 is then inserted into the insert block 4. Then the moving block 6 is reset under the action of the spring 9, and at the same time, the locking block 10 is locked onto the protrusion 11. Then the electric cylinder 7 drives the insert block 5 to move downward and insert into the clamping plate 3, fixing the clamping plate 3 on the support plate 2. This solves the problem of the rigid structure of common wheel hub end milling fixtures, which cannot quickly replace or adjust the clamping jaw assembly, can only adapt to wheel hubs of fixed specifications, and require complete disassembly and reinstallation of the fixture when switching to different shapes, which is time-consuming and greatly affects production efficiency.
