Description

Technical Field

[0001] The present invention relates to the technical field of electric vehicle hub hole position detection, and specifically relates to a device for detecting and positioning the hole positions of an electric vehicle hub. Background Technique

[0002] The detection of the hole positions of an electric vehicle hub is to check and measure the parameters such as the position, size, shape, and spacing of the holes on the electric vehicle hub used for installing components such as tires, wheel spokes, and braking devices. The purpose is to ensure that these hole positions meet the design requirements and relevant standards to ensure that the hub can be correctly installed and used normally, and to ensure the driving safety and stable performance of the electric vehicle. If there are problems such as deviations in hole positions, inconsistent sizes, or irregular shapes, it may lead to difficulties in installation, loosening of components, uneven stress, and even safety accidents. During the use of the electric vehicle hub hole position detection, a positioning device is required to position the electric vehicle hub, so as to facilitate the detection device to detect the hole positions of the hub.

[0003] Most of the existing electric vehicle hub hole position detection and positioning devices use ordinary clamping structures during the working process, that is, the clamping method of fixing one side and moving the other side. Using such a clamping method can only position hubs with standard sizes. If hubs of other sizes are used, a good positioning effect cannot be achieved, resulting in the detection device not being able to detect accurately.

[0004] Therefore, it is necessary to design a device for detecting and positioning the hole positions of an electric vehicle hub for the above problems. Summary of the Invention

The electric vehicle hub body is located on one side of the side clamping component close to the central axis of the power component. The traction component includes a tension sensor, a pull plate, a second spring, a guide rod, and a traction frame. The side of the tension sensor away from the power component is connected with a pull plate, and the middle of the side of the pull plate away from the tension sensor is connected with a second spring.

[0007] Furthermore, a vibration component is installed at the upper end of the power component, a compressed air component is installed around the vibration component, and a cleaning component is connected to the upper end of the side clamping component.

[0008] Further, the power assembly includes a support box, a first motor, and a first gear. The first motor is installed at the lower end of the support box, and the rotating end of the first motor is connected to the first gear.

[0009] Further, the power assembly further includes a second gear, a threaded rod, a moving frame, and a sliding rod. The second gear is meshed and connected around the first gear. The middle of the second gear is connected to the threaded rod, the outside of the threaded rod is connected to the moving frame, and the lower end of the moving frame penetrates through the sliding rod.

[0010] Further, the vibration assembly includes a second motor, a fixing plate, and a rotating telescopic rod. The fixing plate is connected above the second motor, and the rotating end of the second motor is connected to the rotating telescopic rod.

[0011] Further, the vibration assembly further includes a first spring and a contact plate. The first spring is arranged outside the rotating telescopic rod, and the upper end of the rotating telescopic rod is connected to the contact plate.

[0012] Further, the air compression assembly includes an air box, an air pipe, a piston plate, a lifting rod, and a steel ball. The lower end of one side of the air box away from the vibration assembly is connected to the air pipe. A piston plate is installed inside the air box, the upper end of the piston plate is connected to the lifting rod, and the upper end of the lifting rod is inlaid and connected with the steel ball.

[0013] Further, the side clamping assembly includes an airbag, an upper sleeve, a lower sleeve, and a sealing gasket. The upper end of the airbag is connected to the upper sleeve, the lower end of the airbag is connected to the lower sleeve, and the sealing gasket is installed at the lower end inside the lower sleeve.

[0014] Further, the side clamping assembly further includes a bearing and a hard pipe. The bearing is installed inside the upper sleeve, and the hard pipe is connected inside the bearing.

[0015] Further, the cleaning assembly includes a bracket, an arc-shaped frame, a polishing and cleaning column, and an elastic pull belt. The upper end of the bracket is connected to the arc-shaped frame. One end of the arc-shaped frame away from the bracket is connected to the polishing and cleaning column, and the upper end of the arc-shaped frame is connected to the elastic pull belt.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: The device has a central clamping structure. Through the central clamping structure, it is convenient for the device to be positioned. At the same time, relying on the central positioning effect, when the device rotates the wheel hub, it can easily detect whether the shape of the wheel hub is standard, so as to facilitate the staff to discover and handle it in time, removing the possibility of affecting the positioning due to the shape of the wheel hub. At the same time, the central positioning structure also has an auxiliary support effect, which is more convenient for the contact plate to drive the wheel hub to rotate. The device also has a polishing effect during the rotation of the wheel hub, removing the burrs or slight protrusions on the edge of the wheel hub, so as to prevent the burrs or slight protrusions from affecting the shape detection of the device.

[0017] 1. The present invention uses a power component to pull the traction frame, so that the four side clamping components move closer to the middle, enabling the side clamping components to position and clamp the electric vehicle wheel hub body. At the same time, relying on the elastic structure formed by the guide rod, the second spring and the pull plate of the traction frame, a continuous clamping force is exerted on the side clamping components, so that the side clamping components can stably clamp the electric vehicle wheel hub body. The tension sensor can detect the tension of the traction frame, facilitating the power component to control the clamping force of the side clamping components.

[0018] 2. The second motor of the present invention can drive the contact plate to rotate by rotating the telescopic rod, so that the contact plate drives the electric vehicle wheel hub body to rotate. Relying on the elastic structure formed by the contact plate, the first spring, the rotating telescopic rod and the fixed plate, it is convenient for the contact plate to contact and drive the electric vehicle wheel hub body. During the rotation of the electric vehicle wheel hub body, if the side of the electric vehicle wheel hub body is uneven or the shape of the electric vehicle wheel hub body is problematic, it will affect the position of the side clamping components, causing the value of the tension sensor to change, facilitating the staff to discover and solve problems in a timely manner, and avoiding the situation of inaccurate centering due to problems with the electric vehicle wheel hub body itself, which affects subsequent hole position detection.

[0019] 3. When the electric vehicle wheel hub body is placed on the contact plate, the lifting rod presses down the piston plate, and the gas in the air box is transported to the airbag through the air pipe, causing the airbag to expand and contact the side of the electric vehicle wheel hub body, thereby increasing the friction between the side clamping components and the electric vehicle wheel hub body. During the rotation of the electric vehicle wheel hub body, it is more convenient to drive the upper sleeve to rotate. At the same time, the expansion of the airbag can be embedded inside the electric vehicle wheel hub body, forming a good supporting force for the electric vehicle wheel hub body, ensuring the stability of the position of the electric vehicle wheel hub body, and preventing the up and down movement of the electric vehicle wheel hub body during rotation, which affects the operation of the equipment.

[0020] 4. The present invention uses the arc-shaped frame to support the grinding and cleaning column, facilitating the grinding and cleaning column to be flush with the electric vehicle wheel hub body, thus facilitating the cleaning of the surface of the electric vehicle wheel hub body by the grinding and cleaning column, avoiding the burrs or corners on the surface of the electric vehicle wheel hub body from affecting the side clamping components and causing misjudgment of the tension sensor. At the same time, relying on the elastic rotation mechanism directly formed by the arc-shaped frame and the support through the elastic pull belt, it is convenient for the grinding and cleaning column to stably contact the electric vehicle wheel hub body, facilitating the cleaning work of the grinding and cleaning column.

[0030] As Figure 1 and Figure 4As shown in the figure, the present invention provides a technical solution: an electric vehicle hub hole position detection and positioning device, which includes a power component 1 and an electric vehicle hub body 6. A traction component 4 is connected around the power component 1, and a side clamping component 5 is connected to the upper end of the traction component 4. The electric vehicle hub body 6 is located on the side of the side clamping component 5 close to the central axis of the power component 1. The traction component 4 includes a tension sensor 401, a pull plate 402, a second spring 403, a guide rod 404 and a traction frame 405. The side of the tension sensor 401 away from the power component 1 is connected to the pull plate 402, and the middle of the side of the pull plate 402 away from the tension sensor 401 is connected to the second spring 403. The guide rod 404 penetrates through the upper and lower sides of the pull plate 402, and the end of the guide rod 404 away from the pull plate 402 is connected to the traction frame 405;

[0031] The specific operation is as follows. The traction frame 405 is pulled by the power component 1, so that the four side clamping components 5 move closer to the middle, enabling the side clamping components 5 to position and clamp the electric vehicle hub body 6. At the same time, relying on the elastic structure formed between the traction frame 405, the guide rod 404 and the second spring 403 with the pull plate 402, a continuous clamping force is formed on the side clamping components 5, so that the side clamping components 5 can stably clamp the electric vehicle hub body 6. The tension sensor 401 can detect the tension of the traction frame 405, which is convenient for the power component 1 to control the clamping force of the side clamping components 5.

[0032] As Figure 1 、 Figure 3 and Figure 6 shown in the figure, a vibration component 2 is installed at the upper end of the power component 1, and a pneumatic pressure component 3 is installed around the vibration component 2. A cleaning component 7 is connected to the upper end of the side clamping component 5.

[0033] As Figure 2 shown in the figure, the power component 1 includes a support box 101, a first motor 102 and a first gear 103. The first motor 102 is installed at the lower end of the support box 101, and the rotating end of the first motor 102 is connected to the first gear 103. The power component 1 further includes a second gear 104, a threaded rod 105, a moving frame 106 and a sliding rod 107. The second gear 104 is meshed and connected around the first gear 103. The middle of the second gear 104 is connected to the threaded rod 105, and the threaded rod 105 is externally connected to the moving frame 106. The lower end of the moving frame 106 penetrates through the sliding rod 107;

[0034] The first motor 102 drives the first gear 103 to rotate, thereby driving the threaded rod 105 to rotate through the second gear 104. Depending on the threaded connection between the threaded rod 105 and the moving frame 106, the moving frame 106 moves towards the central axis of the support box 101, so that the moving frame 106 drives the side clamping component 5 to clamp the electric vehicle hub body 6.

[0035] like Figure 1 The vibration assembly 2 includes a second motor 201, a fixed plate 202 and a rotating telescopic rod 203, and the second motor 201 is connected to the fixed plate 202 above, and the rotating end of the second motor 201 is connected to the rotating telescopic rod 203. The vibration assembly 2 also includes a first spring 204 and a contact plate 205, and the first spring 204 is arranged outside the rotating telescopic rod 203, and the upper end of the rotating telescopic rod 203 is connected to the contact plate 205;

[0036] The second motor 201 can drive the contact plate 205 to rotate by rotating the telescopic rod 203, so that the contact plate 205 mobilizes the electric vehicle hub body 6 to rotate, and the elastic structure formed by the contact plate 205 through the first spring 204 and the rotating telescopic rod 203 and the fixed plate 202 facilitates the contact between the contact plate 205 and the electric vehicle hub body 6 for transmission. During the rotation of the electric vehicle hub body 6, if the side of the electric vehicle hub body 6 is uneven or the shape of the electric vehicle hub body 6 has problems, it will affect the position of the side clamping assembly 5, thereby changing the value of the tension sensor 401, which is convenient for the staff to find problems in time and solve them, avoiding inaccurate centering due to problems with the electric vehicle hub body 6 itself, affecting subsequent hole position detection.

[0037] like Figure 3 The compressed air component 3 includes an air box 301, an air pipe 302, a piston plate 303, an upgrade rod 304 and a steel ball 305, and the air box 301 is connected to the air pipe 302 at the lower end of the side away from the vibration component 2, the piston plate 303 is installed inside the air box 301, and the upper end of the piston plate 303 is connected to the upgrade rod 304, and the upper end of the upgrade rod 304 is inlaid with a steel ball 305;

[0038] The electric vehicle hub body 6 is placed on the contact plate 205, so that the upgrade rod 304 presses down the piston plate 303, and the gas inside the air box 301 is transported to the air bag 501 through the air pipe 302, so that the air bag 501 expands and contacts the side of the electric vehicle hub body 6, thereby increasing the friction between the side clamping assembly 5 and the electric vehicle hub body 6, making it easier to drive the upper sleeve 502 to rotate during the rotation of the electric vehicle hub body 6. At the same time, the expanded air bag 501 can be embedded in the inside of the electric vehicle hub body 6, and can form a good supporting force for the electric vehicle hub body 6, thereby ensuring the stability of the position of the electric vehicle hub body 6, so that the electric vehicle hub body 6 will not move up and down during the rotation, thereby preventing the electric vehicle hub body 6 from moving up and down and affecting the operation of the equipment.

[0039] like Figure 5 and Figure 7As shown, the side clamping assembly 5 includes an airbag 501, an upper sleeve 502, a lower sleeve 503 and a gasket 504. The upper end of the airbag 501 is connected to the upper sleeve 502, and the lower end of the airbag 501 is connected to the lower sleeve 503. A gasket 504 is installed at the lower end inside the lower sleeve 503. The side clamping assembly 5 further includes a bearing 505 and a hard tube 506. A bearing 505 is installed inside the upper sleeve 502, and a hard tube 506 is connected inside the bearing 505;

[0040] Both the upper sleeve 502 and the lower sleeve 503 form a rotating structure with the hard tube 506 through the bearing 505, which facilitates the rotation of the upper sleeve 502 and the lower sleeve 503 and avoids affecting the rotation of the electric vehicle wheel hub body 6 by the upper sleeve 502 and the lower sleeve 503.

[0041] As Figure 6 and Figure 8 As shown, the cleaning assembly 7 includes a bracket 701, an arc-shaped frame 702, a polishing and cleaning column 703 and an elastic strap 704. The upper end of the bracket 701 is connected to the arc-shaped frame 702. One end of the arc-shaped frame 702 away from the bracket 701 is connected to the polishing and cleaning column 703, and an elastic strap 704 is connected to the upper end of the arc-shaped frame 702;

[0042] The arc-shaped frame 702 supports the polishing and cleaning column 703, so that the polishing and cleaning column 703 is flush with the electric vehicle wheel hub body 6, facilitating the cleaning of the surface of the electric vehicle wheel hub body 6 by the polishing and cleaning column 703 and avoiding the barbs or corners on the surface of the electric vehicle wheel hub body 6 from affecting the side clamping assembly 5 and causing misjudgment of the tensile sensor 401. At the same time, relying on the elastic rotating mechanism directly formed by the arc-shaped frame 702 and the bracket 701 through the elastic strap 704, it is convenient for the polishing and cleaning column 703 to stably contact the electric vehicle wheel hub body 6 and facilitate the cleaning work of the polishing and cleaning column 703.

[0043] Working principle: First, install the device on the hole position detection device, and then place the electric vehicle wheel hub body 6 on the contact plate 205. When the electric vehicle wheel hub body 6 presses down on the contact plate 205, it will drive the lifting rod 304 to move downward, so that the lifting rod 304 pushes the piston plate 303 downward, and the gas inside the air box 301 is pushed through the air pipe 302 to the hard pipe 506, so that the gas escapes from the hard pipe 506 and enters the airbag 501, causing the airbag 501 to expand. At the same time, the first motor 102 drives the first gear 103 to rotate, and then drives the threaded rod 105 to rotate through the second gear 104. Depending on the threaded connection between the threaded rod 105 and the moving frame 106, the moving frame 106 moves towards the central axis direction of the support box 101, so that the moving frame 106 drives the side clamping assembly 5 to clamp the electric vehicle wheel hub body 6. The sliding rod 107 guides the moving frame 106, facilitating the horizontal movement of the moving frame 106, and thus making it easier for the side clamping assembly 5 to clamp the electric vehicle wheel hub body 6. During the clamping process, relying on the elastic structure formed by the traction frame 405 through the guide rod 404 and the second spring 403 with the pull plate 402, a continuous traction effect can be formed on the side clamping assembly 5 to maintain the stability of the device clamping. When the tension sensor 401 detects that the traction force formed by the side clamping assembly 5 reaches a certain value, the first motor 102 is stopped at this time, so that the device completes the clamping. Then, the operator or personnel turn on the second motor 201, drive the contact plate 205 to rotate by rotating the telescopic rod 203, so as to drive the electric vehicle wheel hub body 6 to rotate, and the side clamping assembly 5 detects the shape of the electric vehicle wheel hub body 6. If the side of the electric vehicle wheel hub body 6 is uneven, or there is a problem with the shape of the electric vehicle wheel hub body 6, it will affect the position of the side clamping assembly 5, resulting in a change in the value of the tension sensor 401, which is convenient for the staff to discover and solve problems in time, and avoid the situation of inaccurate centering due to the problems of the electric vehicle wheel hub body 6 itself. Both the upper sleeve 502 and the lower sleeve 503 form a rotating structure with the hard pipe 506 through the bearing 505, facilitating the rotation of the upper sleeve 502 and the lower sleeve 503, and avoiding the influence of the upper sleeve 502 and the lower sleeve 503 on the rotation of the electric vehicle wheel hub body 6. At the same time, relying on the elastic structure formed by the contact plate 205 through the first spring 204 and the rotating telescopic rod 203 with the fixed plate 202, it is convenient for the contact plate 205 to contact the electric vehicle wheel hub body 6, thus facilitating the rotation of the electric vehicle wheel hub body 6. During the process of the side clamping assembly 5 clamping the electric vehicle wheel hub body 6, relying on the elastic rotating structure formed by the arc-shaped frame 702 through the elastic pull belt 704 with the bracket 701, the grinding and cleaning column 703 can make good contact with the electric vehicle wheel hub body 6, so that the grinding and cleaning column 703 cleans the surface of the electric vehicle wheel hub body 6, removing burrs or small protrusions on the surface of the electric vehicle wheel hub body 6, thus avoiding the influence of burrs or small protrusions on the centering detection of the electric vehicle wheel hub body 6 and avoiding the operation of the device. When all the above work is completed,Thus, it ensures the accurate centering of the device on the electric vehicle wheel hub body 6, facilitating the operation of the hole position detection device. After the hole position detection is completed, the first motor 102 is turned on in reverse, so that the side clamping assembly 5 releases the electric vehicle wheel hub body 6, facilitating the staff to take out the electric vehicle wheel hub body 6.,
