Description

Technical Field

[0001] The present application relates to the technical field of automobile wheel hub processing, and specifically discloses a processing device for intelligent manufacturing of automobile wheel hubs. Background Art

[0002] The automobile wheel hub is the part in the center of the wheel where the axle is installed. It is also a cylindrical metal part with the inner profile of the tire supporting the tire and the center assembled on the axle.

[0003] Wheels can be divided into steel wheels and alloy wheels according to their materials. Steel wheels have simple manufacturing process, relatively low cost, and strong resistance to metal fatigue, but they are not very beautiful in appearance, heavy, have large inertial resistance, and poor heat dissipation. Alloy wheels make up for these shortcomings, with lighter weight, smaller inertial resistance, high-precision manufacturing, and good heat dissipation, which is conducive to improving the straight-line driving performance of the car and reducing fuel consumption;

[0004] Automobile wheel hub grinding is an essential part of automobile wheel hub processing;

[0005] At present, the following difficulties exist in the surface treatment process of automobile wheel hub manufacturing: a. After the automobile wheel hub is cast and formed, there will be many burrs on its surface, which is not smooth and flat, so it cannot be used directly and needs to be polished. The traditional polishing method is to polish with a manual grinding wheel, which requires manual pressing and fixing, which is time-consuming and labor-intensive, resulting in low polishing efficiency and high work intensity; b. The existing polishing device polishes the inner and outer walls of the wheel hub in steps during polishing, and fails to polish the inner and outer walls of the wheel hub at the same time. Since the wheel hub needs to be fixed before polishing, the step-by-step polishing requires the wheel hub to be fixed twice, which has high work intensity;

[0006] China Publication No. CN113059413B discloses a surface treatment processing machine for automobile wheel hub manufacturing, which realizes the simultaneous grinding of the inner and outer side walls of the wheel hub, improving the grinding efficiency, but there are also shortcomings. The outer grinding block in the above scheme is not reasonable;

[0007] First of all, the external grinding block is aimed at the rim, which is the wheel part that cooperates with the tire and supports the tire. It provides the load-bearing support for the vehicle, but does not act on the rim, that is, the external source line of the car wheel hub, resulting in insufficient grinding. Secondly, when using the external grinding block to act on the rim, it is actually not easy to use, because the wheel hub has different sizes, that is, the width of the rim is not fixed, and the use of the above-mentioned external grinding block will lead to the problem of insufficient grinding;

[0008] Furthermore, from the perspective of actual grinding, if an external grinding block is used to directly and hard contact the upper barb on the rim, the external grinding block will be severely worn without long-term use. In view of this, the inventor proposes a processing device for intelligent manufacturing of automobile wheels. Summary of the invention

[0009] The invention aims to solve the problem that the rim grinding of the conventional automobile wheel hub is insufficient and incomplete in the outer ring grinding.

[0010] In order to achieve the above object, the present invention provides the following basic scheme:

[0011] A processing device for intelligent manufacturing of automobile wheel hubs, comprising a workbench, a motor arranged at the bottom of the workbench, the output shaft of the motor passing through a connecting shaft coaxially connected to the workbench, the connecting shaft being connected to a wheel hub to be processed and a handpiece for distance measurement, and the four sides of the workbench being connected to a first clamping piece, a second clamping piece and a third clamping piece;

[0012] The first clamping member and the second clamping member have the same structure and act on the upper side and the lower side of the wheel hub respectively. A fixing member for fixing the wheel hub is provided at the connection between the connecting shaft and the wheel hub;

[0013] After the first clamping member and the second clamping member act on the upper side and the lower side of the wheel hub, the centerline distance of the wheel hub is obtained based on the handpiece as a reference point;

[0014] The third clamping member includes a fixing member whose initial position is flush with the handpiece, a third sliding assembly for pushing the fixing member to move up and down, a third pushing assembly installed on the third sliding assembly for pushing the fixing member to move horizontally, and a grinding block detachably connected to the fixing member, wherein the third sliding assembly moves the fixing member to the center line of the wheel hub.

[0015] The principles and effects of this basic solution are:

[0016] 1. Compared with the prior art, the device has a simple structure and an ingenious design. The core of the device is that it has outstanding advantages in grinding the outer ring of automobile wheels, mainly because it can act on the rim, thereby solving the problem of insufficient and incomplete rim grinding in the outer ring grinding of traditional automobile wheels.

[0017] 2. Compared with the prior art, the device can fully grind the outer ring of the automobile wheel hub and can be applied to wheels of different sizes, thereby improving the universality and practicality of the device.

It has a good effect on the wheel hub grinding in the automobile wheel hub processing link and can achieve better wheel hub outer ring grinding.

[0018] 3. Compared with the prior art, the present device is designed with upper clamping components and lower clamping components suitable for wheels of different sizes. The transverse center line of the wheel hub is found intelligently based on the upper clamping components and the lower clamping components. The grinding block is flexibly installed based on the position of the transverse center line, so that the grinding block can act on the outer ring of the wheel hub.

[0019] 4.

The upper clamping assembly, the lower clamping assembly and the grinding block in the present device all adopt a mode of gradually applying force. Considering that the barbs on the hub have depth, there is no one-step grinding mode, but a mode of gradually grinding off the barbs. The advantage of this mode is that it increases the service life of the upper clamping assembly, the lower clamping assembly and the grinding block, and secondly, it avoids splashing and scratching on the smooth hub surface caused by the rapid breaking of the barbs.

[0020] 5. Compared with the prior art, the present device adopts a mode of gradually grinding off the barbs, and the gradual advancement process of the upper clamping assembly, the lower clamping assembly and the grinding block is directly related to the number of rotations of the wheel hub. Since the number of rotations of the wheel hub determines the degree of grinding, the gradual advancement process of the upper clamping assembly, the lower clamping assembly and the grinding block is directly related to the number of rotations of the wheel hub, so that the wheel hub grinding becomes a step-by-step grinding, and finally the mode of gradually grinding off the barbs by the present device is realized.

[0040] Implementation example Figure 1 , Figure 2 , Figure 3 , Figure 4, Figure 5 , Figure 6 and Figure 7 As shown:

[0041] A processing device for intelligent manufacturing of automobile wheel hubs, comprising a workbench 1, a motor 20 arranged at the bottom of the workbench 1, an output shaft of the motor 20 passing through a connecting shaft 19 coaxially connected to the workbench 1, a wheel hub 17 to be processed and a handpiece for distance measurement are connected to the connecting shaft 19, and a first clamping member, a second clamping member and a third clamping member are connected around the workbench 1;

[0042] About Workbench 1:

[0043] A number of support columns 2 are evenly arranged around the bottom of the workbench 1, and the free ends of the support columns 2 are fixed with anti-slip pads. The motor 20 is installed on the same side of the support columns 2. The connecting shaft 19 and the wheel hub 17 are detachably connected, and a locking piece is provided at the connection between the connecting shaft 19 and the wheel hub 17.

[0044] Regarding the locking part: the purpose is to fix the wheel hub 17, and the core is to utilize the screw holes of the wheel hub 17. Specifically: the locking part includes a plurality of latch bolts 22, an end cover 18 and a locking nut. The latch bolts 22 all pass through the screw holes of the wheel hub 17, one end of the latch bolts 22 is connected to the end cover 18, and the other end of the latch bolts 22 is threadedly connected to the locking nut. When the wheel hub 17 is fixed on the connecting shaft 19, the position of the wheel hub 17 is higher than the handpiece.

[0045] The reason why the hub 17 is located higher than the handpiece is mainly because a certain space needs to be provided between the hub 17 and the handpiece to facilitate the subsequent operation of the first clamping member and the second clamping member;

[0046] The hand piece includes a turntable 8 rotatably connected to a connecting shaft 19 , a handle 10 fixed to the outer periphery of the turntable 8 , and a groove 9 opened on the end surface of the turntable 8 , wherein a distance sensing receiving target 23 is flushly arranged in the groove 9 .

[0047] The handle 10 can be used when the motor 20 is not moving and does not want to rotate automatically. The handle 10 can be rotated to drive the connecting shaft 19 to rotate, and finally the wheel hub 17 can be rotated.

[0048] The first clamping member and the second clamping member have the same structure and act on the upper side and the lower side of the wheel hub 17 respectively. A fixing member for fixing the wheel hub 17 is provided at the connection between the connecting shaft 19 and the wheel hub 17;

[0049] After the first clamping member and the second clamping member act on the upper side and the lower side of the wheel hub 17, the centerline distance of the wheel hub 17 is obtained based on the handpiece as a reference point;

[0050] Regarding the first clamping member and the second clamping member:

[0051] The first clamping member includes a first motor arranged in the workbench 1, a first threaded shaft 6 coaxially connected to the first motor, a collar 11 threadedly connected to the first threaded shaft 6, a mounting plate 16 fixed to the collar 11, a contact plate 21 fixed to the free end of the mounting plate 16, a first cylinder 14 arranged on the mounting plate 16, and a first friction block 15 arranged at the protruding end of the first cylinder 14, wherein the first friction block 15 contacts the outer periphery of the wheel hub 17;

[0052] The contact plate 21 contacts the lower end surface of the wheel hub 17, the contact plate 21 in the second clamping member contacts the upper end surface of the wheel hub 17, a pressure sensor 24 and a distance sensor transmitter 25 are flush mounted on the contact plate 21, the distance sensor transmitter 25 is connected to the distance sensor receiving target signal, and the pressure sensor 24 is connected to the third sliding component signal;

[0053] Likewise, for the second clamp:

[0054] The second clamping member includes a second motor arranged in the workbench 1, a second threaded shaft 5 coaxially connected to the second motor, a collar 11 threadedly connected to the second threaded shaft 5, a mounting plate 16 fixed to the collar 11, a contact plate 21 fixed to the free end of the mounting plate 16, a second cylinder arranged on the mounting plate 16, and a second friction block arranged at the protruding end of the second cylinder, wherein the second friction block contacts the outer periphery of the wheel hub 17;

[0055] The contact plate 21 contacts the upper end surface of the wheel hub 17, the contact plate 21 in the second clamping member contacts the upper end surface of the wheel hub 17, a pressure sensor 24 and a distance sensor transmitter 25 are flush mounted on the contact plate 21, the distance sensor transmitter 25 is connected to the distance sensor receiving target signal, and the pressure sensor 24 is connected to the third sliding component signal;

[0056] like Figure 3 As shown:

[0057] It also includes a display 3 set on the workbench 1, a processor and a controller built into the display 3, the processor includes a processing chip and a distance conversion module, the controller is a signal controller, the total width of the hub 17 is obtained through the upper contact plate 21 and the lower contact plate 21, the center line length of the hub 17 is obtained through the processing chip, and the distance is converted to the third sliding component through the distance conversion module. The third sliding component pushes the fixed part to move an amount equal to the center line length of the hub 17.

[0058] Specific:

[0059] When the upper contact plate 21 and the lower contact plate 21 contact their respective end faces of the hub 17, since the pressure sensor 24 and the distance sensor transmitter 25 are installed flush, the distances are subtracted through an algorithm to obtain the total width of the hub 17, and then the distance conversion module processes the total width of the hub 17 to obtain the centerline distance of the hub 17, that is, half of the total width of the hub 17, and then this half distance is used as the movement amount of the fixing part;

[0060] About the third clamping piece:

[0061] The third clamping member includes a fixing member whose initial position is flush with the handpiece, a third sliding assembly for pushing the fixing member to move up and down, a third pushing assembly installed on the third sliding assembly for pushing the fixing member to move horizontally, and a grinding block detachably connected to the fixing member, wherein the third sliding assembly moves the fixing member to the center line of the hub 17.

[0062] Specific:

[0063] The third sliding assembly includes a third motor arranged in the workbench 1, a third threaded shaft 4 coaxially connected to the third motor, and a cavity mounting block 12 sleeved on the third threaded shaft 4. The fixing part is slidably connected to the lower surface of the cavity mounting block 12. The first clamping part, the second clamping part and the third sliding assembly are all provided with a limiting rod 7 for realizing up and down sliding.

[0064] Specifically: the rotation amount of the third motor drives the cavity mounting block 12 to move an amount equal to half of the above distance, so that the cavity mounting block 12 moves to the center line of the wheel hub 17 and stops, and then a suitable grinding block is installed;

[0065] About the sanding block:

[0066] The fixing member includes a transverse plate 13, a connecting plate 26 detachably connected to the transverse plate 13, and a locking screw 27 for locking the transverse plate 13 and the connecting plate 26. A load-bearing plate 28 is fixedly connected to the free end of the connecting plate 26. The load-bearing plate 28 is fixedly connected to the grinding block. The grinding block includes a main grinding block 29 and an auxiliary grinding block 33. The auxiliary grinding block 33 is detachably connected to both ends of the main grinding block 29.

[0067] The third pushing assembly includes a cavity opened in the cavity mounting block 12, a pushing cylinder 35 arranged in the cavity and a pushing plate 36 arranged at the protruding end of the cylinder, the pushing plate 36 is fixedly connected to the cross plate 13, and a telescopic rod 37 is provided on the inner wall on the other side of the cavity away from the cavity, and the telescopic end of the telescopic rod 37 is connected to the pushing plate 36.

[0068] Specific:

[0069] That is, the transverse plate 13 is located at the center line of the wheel hub 17, and then the locking screws 27 and the connecting plate 26 are used to make the fixing member close to the outer periphery of the wheel hub 17, and then the connecting plate 26 of a suitable size is selected according to the width of the wheel hub 17. Since the free end of the connecting plate 26 is fixedly connected with the bearing plate 28, and the bearing plate 28 is fixedly connected with the grinding block, the auxiliary grinding block 33 is provided with a latch 34, and the main grinding block 29 and the auxiliary grinding block 33 are connected by the latch 34, and then the outer periphery of the wheel hub 17 is ground by the grinding block;

[0070] It also includes a connecting frame, which includes a bent frame 30, a first bracket 31 and a second bracket 32 ​​arranged at both ends of the bent frame 30, and the first bracket 31 and the second bracket 32 ​​are respectively installed on the load-bearing plate 28 and the connecting plate 26 to improve the stability of the device.

[0071] The core of this case lies in:

[0072] The device adopts a mode of gradually grinding off the barbs, and the gradual advancement process of the upper clamping assembly, the lower clamping assembly and the grinding block is directly associated with the number of rotations of the wheel hub 17. Since the number of rotations of the wheel hub 17 determines the degree of grinding, the gradual advancement process of the upper clamping assembly, the lower clamping assembly and the grinding block is directly associated with the number of rotations of the wheel hub 17, so that the grinding of the wheel hub 17 becomes a step-by-step grinding, and finally the mode of gradually grinding off the barbs of the device is realized;

[0073] Regarding the upper clamping assembly and the lower clamping assembly: the first cylinder 14 and the second cylinder are used to push the first friction block 15 and the second friction block to gradually contact the outer periphery of the wheel hub 17, and the movement of the first cylinder 14 and the second cylinder depends on the number of revolutions of the wheel hub 17, and then it can be intelligent, for example, after how many revolutions, how many mm is advanced;

[0074] The same is true for the third clamping member. The size of the grinding block is set to multiple standard parts. Because the size of the automobile wheel hub 17 is basically a conventional size, it is relatively small. Then, the size of the grinding block can be set to multiple standard parts. Then, for the grinding block, the pushing cylinder 35 realizes the pushing of the grinding block. The movement of the pushing cylinder 35 depends on the number of rotations of the wheel hub 17. Then, it can be intelligent, for example, after how many rotations, how many mm is pushed;

[0075] Another reason for setting the size of the grinding block to multiple standard parts is installation. Since the grinding block is installed based on the cross plate 13, the cross plate 13 is on the center line of the wheel hub 17. Therefore, after setting the size of the grinding block to multiple standard parts, installation is very easy, because standard parts have a center, that is, symmetry, and normal installation can ensure that the grinding block can cover and grind off the outer circumference of the wheel hub 17.

[0076] The device solves the problem of insufficient and incomplete rim grinding in the outer ring grinding of the traditional automobile wheel hub 17.

Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
