Description

Technical Field

[0001] This utility model relates to the field of coating machine technology, and in particular to a wheel hub vacuum coating machine. Background Technology

[0002] A wheel hub is a cylindrical metal component that supports the tire and is mounted on an axle. It is also called a steel rim or wheel. During the manufacturing process, the outer surface of the wheel hub needs to be coated. This process requires a vacuum coating machine, which mainly refers to a type of coating that needs to be carried out under a high vacuum. Specifically, it includes vacuum resistance heating evaporation and electron gun heating evaporation.

[0003] A search revealed that patent CN220665419U discloses a wheel hub vacuum coating machine, which achieves the fixation of different models of wheel hubs by adjusting the distance between two hanging rods.

[0004] However, when the aforementioned wheel hub vacuum coating machine fixes the wheel hub, it only uses limiting plates to clamp and fix the two sides of the wheel hub. This causes the hanging rod to easily wobble between the limiting plates during the rotation of the wheel hub, thus falling off the hanging rod and affecting the coating. Therefore, further improvement is needed. To this end, we have proposed a wheel hub vacuum coating machine. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a vacuum coating machine for wheel hubs.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a wheel hub vacuum coating machine, comprising a base, a vacuum coating chamber fixedly installed at the upper end of the base, a sealing door movably installed on the front side of the vacuum coating chamber, a first motor fixedly installed inside the base, the output shaft of the first motor passing through the bottom of the vacuum coating chamber and fixedly installed with a coupling, the first motor being fixedly connected to a turntable via the coupling, a fixed frame fixedly installed at the upper end of the turntable, a second motor fixedly installed at the top of the fixed frame, the second motor being rotatably mounted on the upper inner wall of the vacuum coating chamber, the output shaft of the second motor being fixedly connected to a lead screw via a coupling, movable slots symmetrically opened on the upper and lower sides of the fixed frame, two mounting blocks threadedly connected to the circumferential surface of the lead screw, the mounting blocks being movably installed in the movable slots, fixed rods being evenly fixedly installed on the outer side of the mounting blocks, fixed plates being evenly fixedly installed around the outer perimeter of the fixed frame, connecting rods being fixedly installed below the end of the fixed rod away from the mounting block and on the upper side of the fixed plate away from the mounting block, respectively, and a fixed block being fixedly installed at the end of the connecting rod away from the fixed rod and the fixed plate.

[0007] Furthermore, support legs are fixedly installed at the four corners of the base, and shock-absorbing pads are fixedly installed at the bottom of the support legs; this allows the support legs, along with the base and vacuum coating chamber, to be moved to a position that is more convenient for operators to operate. At the same time, the shock-absorbing pads fixedly installed at the bottom of the support legs can reduce the reaction force between the support legs and the ground during operation, thereby ensuring the working effect of the support legs.

[0008] Furthermore, a handle is fixedly installed on the front left side of the sealed door, and the surface of the handle is provided with anti-slip strips; this can increase the friction between the handle and the worker's palm, thereby making it easier and more convenient for the worker to open and close the sealed door.

[0009] Furthermore, the fixing block has symmetrical through slots on its left and right sides. A rod is movably installed in each slot. A clamping plate is fixedly installed at the outward-facing end of the rod, and a clamping block is fixedly installed on the opposite side of the clamping plate. A pressing block is fixedly installed at the inward-facing end of the rod, and the pressing block is movably installed in the through slot. A spring is movably fitted onto the circumferential surface of the rod, and the spring is movably installed in the through slot. One end of the spring abuts against the inner wall of the through slot, and the other end abuts against the side wall of the pressing block. When the mounting block, via the fixing rod, brings the upper fixing block against the upper end of the wheel hub, the left and right sides of the wheel hub will press against the clamping block. Then, the clamping block moves along with the rod via the clamping plate, and the rod presses against the spring via the pressing block. The reaction force of the spring causes the clamping plate and clamping block to more stably fix the wheel hub, increasing its stability and preventing it from detaching from the fixing block during the coating process, thus affecting the coating effect.

[0010] Furthermore, the side of the fixing block away from the connecting rod is set in an arc shape; this allows the fixing block to fix the wheel hub more stably and improves the coating efficiency of the wheel hub.

[0011] Furthermore, the extrusion block is a rectangular block, and the sagittal cross-sectional dimension of the extrusion block is consistent with the sagittal cross-sectional dimension of the through groove; this can reduce the gap between the extrusion block and the through groove, and at the same time allow the extrusion block to move more stably with the clamping plate and the clamping block through the insert rod, thereby avoiding the clamping plate from deflecting and affecting the fixing effect on the wheel hub.

[0012] The beneficial effects of this utility model are:

[0013] 1. In use, the operator opens the sealed door and places the wheel hub on the fixed block mounted on the fixed plate. Then, the second motor is started, causing it to move the mounting block via a lead screw. This allows the mounting block, through a fixed rod, to abut against the upper end of the wheel hub, thus securing the wheel hub and preventing it from detaching from the fixed block during rotation, which would affect the coating efficiency. The sealed door is then closed, and the first motor is started, causing the fixed frame to rotate via a turntable. The vacuum coating chamber then converts the coating material into gaseous particles and deposits them on the surface of the wheel hub to form a thin film. Simultaneously, the rotation of the fixed frame, through the mounting block, causes the fixed rod and fixed plate to rotate, which in turn causes the wheel hub to rotate, resulting in a more comprehensive coating of the wheel hub and improved coating efficiency.

[0014] 2. When this utility model is in use, when the mounting block, along with the fixing rod, abuts against the upper end of the wheel hub, the left and right sides of the wheel hub will press against the clamping block. Then, the clamping block moves along the clamping plate with the insert rod, and the insert rod presses against the spring through the pressing block. Thus, the reaction force of the spring causes the clamping plate and clamping block to fix the wheel hub more stably, increasing the stability of the wheel hub and preventing the wheel hub from falling off the fixing block during the coating process, which would affect the coating effect.

Detailed Implementation

[0022] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1-4 As shown, a wheel hub vacuum coating machine is disclosed, comprising a base 1, a vacuum coating chamber 3 fixedly mounted on the upper end of the base 1, a sealing door 4 movably mounted on the front side of the vacuum coating chamber 3, a first motor 6 fixedly mounted inside the base 1, the output shaft of the first motor 6 passing through the bottom of the vacuum coating chamber 3 and fixedly mounted with a coupling, the first motor 6 being fixedly connected to a turntable 7 via the coupling, a fixed frame 8 fixedly mounted on the upper end of the turntable 7, a second motor 9 fixedly mounted on the top of the fixed frame 8, the second motor 9 being rotatably mounted on the upper inner wall of the vacuum coating chamber 3, and the output shaft of the second motor 9 being connected to a turntable 7 via a coupling. The device is fixedly connected to a lead screw 10. The upper and lower sides of the fixed frame 8 are symmetrically provided with movable slots 11. Two mounting blocks 12 are threadedly connected to the circumferential surface of the lead screw 10. The mounting blocks 12 are movably installed in the movable slots 11. Fixed rods 13 are evenly fixedly installed on the outer side of the mounting blocks 12. Fixed plates 14 are evenly fixedly installed on the outer perimeter of the fixed frame 8. Connecting rods 15 are fixedly installed on the lower side of the fixed rod 13 away from the mounting block 12 and on the upper side of the fixed plate 14 away from the mounting block 12, respectively. A fixed block 16 is fixedly installed on the end of the connecting rod 15 away from the fixed rod 13 and the fixed plate 14.

[0024] In this embodiment, the operator opens the sealing door 4, places the wheel hub on the fixing block 16 fixedly installed on the fixing plate 14, starts the second motor 9, and moves the mounting block 12 via the lead screw 10. The mounting block 12 moves synchronously with the fixing rod 13. The fixing rod 13 and the upper fixing block 16 abut against the upper end of the wheel hub. Then the sealing door 4 is closed and the first motor 6 is started, rotating the fixing frame 8 via the turntable 7. The vacuum coating chamber 3 converts the coating material into gaseous particles and deposits them on the surface of the wheel hub to form a thin film. At the same time, as the fixing frame 8 rotates, the fixing rod 13 and the fixing plate 14 rotate via the mounting block 12, thereby allowing the fixing rod 13 and the fixing plate 14 to rotate via the fixing block 16.

[0025] Specifically, support legs 2 are fixedly installed at the four corners of the bottom of the base 1, and shock-absorbing pads are fixedly installed at the bottom of the support legs 2.

[0026] By fixing support legs 2 at the four corners of the bottom of the base 1, the support legs 2 can move the base 1 and the vacuum coating chamber 3 to a position that is more convenient for the staff to operate.

[0027] Specifically, a handle 5 is fixedly installed on the front left side of the sealed door 4, and the surface of the handle 5 is provided with anti-slip strips;

[0028] By setting anti-slip strips on the surface of handle 5, the friction between handle 5 and the palm of the operator can be increased, making it easier and more convenient for the operator to open and close the sealed door 4.

[0029] Specifically, through slots 17 are symmetrically opened on the left and right sides of the fixing block 16. A rod 18 is movably installed in the through slot 17. A clamping plate 19 is fixedly installed on the outward end of the rod 18. A clamping block 20 is fixedly installed on the opposite side of the clamping plate 19. A pressing block 21 is fixedly installed on the inward end of the rod 18. The pressing block 21 is movably installed in the through slot 17. A spring 22 is movably sleeved on the circumferential surface of the rod 18. The spring 22 is movably installed in the through slot 17. One end of the spring 22 abuts against the inner side wall of the through slot 17, and the other end of the spring 22 abuts against the side wall of the pressing block 21.

[0030] By symmetrically opening through slots 17 on the left and right sides of the fixing block 16, when the mounting block 12, through the fixing rod 13, brings the upper fixing block 16 to abut against the upper end of the wheel hub, the left and right sides of the wheel hub will squeeze the clamping block 20. Then the clamping block 20 moves through the clamping plate 19 and the insert rod 18. Then the insert rod 18 squeezes the spring 22 through the compression block 21, so that the reaction force of the spring 22 will more stably fix the wheel hub with the clamping plate 19 and the clamping block 20.

[0031] Specifically, the side of the fixing block 16 away from the connecting rod 15 is set in an arc shape;

[0032] By setting the side of the fixing block 16 away from the connecting rod 15 to be arc-shaped, the fixing block 16 can more stably fix the wheel hub, thereby improving the coating efficiency of the wheel hub.

[0033] Specifically, the extrusion block 21 is a rectangular block, and the sagittal cross-sectional dimensions of the extrusion block 21 are consistent with the sagittal cross-sectional dimensions of the through groove 17;

[0034] By setting the extrusion block 21 as a rectangular block and making the sagittal cross-sectional dimension of the extrusion block 21 consistent with the sagittal cross-sectional dimension of the through groove 17, the gap between the extrusion block 21 and the through groove 17 can be reduced. At the same time, the extrusion block 21 can move more stably with the clamping plate 19 and the clamping block 20 through the insert rod 18.

[0035] Working principle: The operator opens the sealed door 4, then places the wheel hub on the fixed block 16 fixedly installed on the fixed plate 14. The second motor 9 is then started, causing the mounting block 12 to move via the lead screw 10. The mounting block 12 then moves synchronously with the fixing rod 13. When the mounting block 12, along with the fixing rod 13, abuts against the upper end of the wheel hub with the upper fixed block 16, the left and right sides of the wheel hub will press against the clamping block 20. The clamping block 20 then moves via the clamping plate 19, carrying the insertion rod 18. The insertion rod 18 then presses against the spring 22 via the compression block 21. The reaction force of spring 22 causes clamping plate 19 and clamping block 20 to fix the wheel hub more stably. Then, the sealing door 4 is closed and the first motor 6 is started. The first motor 6 drives the fixing frame 8 to rotate through turntable 7. Then, the vacuum coating chamber 3 converts the coating material into gaseous particles and deposits them on the surface of the wheel hub to form a thin film. At the same time, during the rotation of the fixing frame 8, the fixing rod 13 and fixing plate 14 are rotated through mounting block 12. Thus, the fixing rod 13 and fixing plate 14 drive the wheel hub to rotate through fixing block 16, so that the wheel hub can be coated more comprehensively and the coating efficiency can be improved.
