Technical Field

[0001] The utility model relates to the technical field of hub processing, in particular to a hub riser size measuring instrument. Background Art

[0002] A hub is a cylindrical metal component that supports the tire inside the tire profile and is centered on the axle.

[0003] The coaxiality requirement of the hub is very precise. For the hub after production and processing, the operator will conduct spot checks, but this spot check method cannot achieve 100% inspection. Due to manual material separation and changes during the use of equipment tools, the size of the drilled riser product is unqualified. When the size of the hub center riser is drilled too large, the next machining process cannot be reprocessed according to the set size, resulting in the flow of quality waste products; when the hub is detected without being straightened directly, it is difficult for the detection instrument to correspond to the hub center hole, thereby affecting the detection efficiency of the hub center hole. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problem of the flow of unqualified products caused by the incomplete detection of the hub center hole size in the prior art, and to propose a hub riser size measuring instrument.

The output end of the cylinder is fixedly connected with a detection instrument for detecting the hub riser. A limiting component for limiting the hub is installed on the fixing frame, and an identification component for identifying the hub is installed on the base;

[0007] An audible and visual alarm electrically connected to the controller is fixedly installed on the fixing frame, and a magnetic switch electrically connected to the audible and visual alarm is arranged on the base;

[0008] The limiting component includes a motor fixedly installed on the fixing frame, the output end of the motor is fixedly connected with a first bidirectional lead screw, a second bidirectional lead screw rotationally installed on the fixing frame and in transmission connection with the first bidirectional lead screw, two nuts are slidably sleeved on the first bidirectional lead screw and the second bidirectional lead screw, and a connecting end is fixedly installed on the nut. A clamping column for clamping the hub is fixedly installed on the connecting end;

[0009] The fixing frame is provided with a long hole for guiding the connecting end, the clamping column is vertically arranged, and a support plate is integrally connected between two corresponding clamping columns, a telescopic rod 1 is fixedly installed on the support plate, and a clamping plate for clamping the wheel hub is fixedly installed on the telescopic rod 1.

[0010] Preferably, the bidirectional screw rod 1 and the bidirectional screw rod 2 are both arranged horizontally, and a transmission belt is connected between the bidirectional screw rod 1 and the bidirectional screw rod 2.

[0011] Preferably, the identification component includes a Keyence camera disposed on a base and electrically connected to a controller for identifying wheel hub labels, a telescopic rod 2 electrically connected to the Keyence camera is disposed on the base, and a contact plate for contacting the wheel hub is fixedly mounted on the telescopic rod 2.

[0012] Compared with the prior art, the utility model has the following advantages:

[0013] 1.

[0022] A sound and light alarm 6 electrically connected to the controller is fixedly mounted on the fixing frame 3, and a magnetic switch 7 electrically connected to the sound and light alarm 6 is provided on the base 1. When the moving distance of the detection device 5 increases, a signal is sent to the magnetic switch 7, and the magnetic switch 7 immediately sends a signal to the sound and light alarm 6 and the controller, so that the sound and light alarm 6 can warn the operator, and the controller sends a stop command to the detection device, waiting for the operator to proceed;

[0023] A limiting assembly for limiting the position of the wheel hub is installed on the fixing frame 3;

[0024] The limit assembly includes a motor 8 fixedly mounted on a fixed frame 3, and a bidirectional screw rod 1 9 is fixedly connected to the output end of the motor 8, a bidirectional screw rod 2 10 is rotatably mounted on the fixed frame 3 and is transmission-connected to the bidirectional screw rod 1 9, the bidirectional screw rod 1 9 and the bidirectional screw rod 2 10 are both horizontally arranged, and a transmission belt 11 is connected between the bidirectional screw rod 1 9 and the bidirectional screw rod 2 10, and the transmission belt 11 adopts a chain drive, which has the advantages of no slippage and high transmission efficiency, ensuring the same-speed and same-direction transmission between the bidirectional screw rod 1 9 and the bidirectional screw rod 2 10;

[0025] A sliding sleeve is provided on the bidirectional lead screw one 9 and the bidirectional lead screw two 10 with two matching nuts 12, and a connecting end 13 is fixedly installed on the nut 12, and a clamping column 14 for clamping the wheel hub is fixedly installed on the connecting end 13. After the motor 8 is driven, the four clamping columns 14 gradually approach the wheel hub and straighten the wheel hub, so that the wheel hub can correspond to the detection instrument 5 during detection;

[0026] A long hole for guiding the connecting end 13 is provided on the fixing frame 3. The clamping column 14 is vertically arranged, and a support plate 15 is integrally connected between two corresponding clamping columns 14. A first telescopic rod 16 is fixedly installed on the support plate 15, and a clamping plate 17 for clamping the wheel hub is fixedly installed on the first telescopic rod 16. The long hole plays a role in guiding the connecting end 13, thereby limiting the moving direction of the nut 12;

[0027] An identification component for the wheel hub is installed on the base 1;

[0028] The identification component includes a Keyence camera 19 installed on the base 1 and electrically connected to the controller for identifying the wheel hub label. An extension rod two 18 electrically connected to the Keyence camera 19 is provided on the base 1, and a contact plate 20 for contacting the wheel hub is fixedly installed on the extension rod two 18;

[0029] The Keyence camera 19 can identify the label adhered to the wheel hub, can determine the specific wheel type of the wheel hub according to the two-dimensional code information system and transmit it to the controller. If the Keyence camera 19 fails to identify the specific information of the wheel hub, a signal is immediately sent to the extension rod two 18, so that the extension rod two 18 drives the contact plate 20 to contact the wheel hub, disconnecting the wheel hub from the conveyor belt 2, and determining the wheel hub information manually;

[0030] It should be noted that the specific model specifications of the conveyor belt 2, the air cylinder 4, the sound and light alarm 6, the magnetic switch 7, the motor 8, the first telescopic rod 16, the second telescopic rod 18, and the Keyence camera 19 need to be selected according to the actual specifications of the device. The specific selection calculation method uses the existing technology in this field, so it will not be elaborated.

[0031] The functional principle of the present utility model can be described through the following operation methods:

[0032] The label marked with the wheel type is adhered to the wheel hub, and the conveyor belt 2 conveys the wheel hub;

[0033] The conveyor belt 2 drives the wheel hub to move to the position below the Keyence camera 19. When the Keyence camera 19 identifies, it determines the specific wheel type of the wheel hub through the two-dimensional code information system on the label and transmits it to the controller;

[0034] After the identification of the wheel hub is completed, the conveyor belt 2 drives the wheel hub to move to the position below the fixing frame 3;

[0035] When the Keyence camera 19 cannot recognize the information on the wheel hub, it immediately sends a command to the telescopic rod 18, and the output end of the telescopic rod 18 drives the contact plate 20 to contact the wheel hub, so that the wheel hub is disconnected from the conveyor belt 2 and is manually confirmed;

[0036] The output end of the motor 8 drives the bidirectional screw rod 1 9 to rotate, and the bidirectional screw rod 1 9 drives the bidirectional screw rod 2 10 to rotate through the transmission belt 11. When the bidirectional screw rod 1 9 and the bidirectional screw rod 2 10 rotate, they drive the two nuts 12 to move in the opposite direction or in the opposite direction.

[0037] When the two nuts 12 move toward each other, the connecting end 13 is driven to slide in the long hole, so that the connecting end 13 drives the clamping column 14 to move toward each other. The clamping column 14 can straighten the wheel hub when moving, and the output end of the telescopic rod 16 is extended and the clamping plate 17 limits the wheel hub from both sides.

[0038] The conveyor belt 2 stops running, and the output end of the cylinder 4 drives the detection device 5 to move downward, and the detection device 5 can detect the size of the hub riser;

[0039] When the detection device 5 does not extend into the center hole of the hub and the magnetic switch 7 does not receive a signal, the detection device 5, the clamping column 14, and the clamping plate 17 return to the initial position, and the conveyor belt 2 drives the hub to continue to move;

[0040] When the detection device 5 extends into the center hole of the wheel hub, the magnetic switch 7 immediately sends a signal to the sound and light alarm 6 and the controller, so that the sound and light alarm 6 can warn the operator, and the controller sends a stop command to the detection equipment and waits for the operator to proceed.

[0041] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
