Description

Technical Field

[0001] The present application relates to the field of clamp equipment, and in particular to a centering clamp. Background Art

[0002] The wheel hub is a cylindrical metal part that supports the tire with its inner profile and is mounted on an axle. It is also called a wheel rim, steel rim, wheel, or tire bell. There are many types of wheel hubs depending on their diameter, width, molding method, and material.

[0003] In the related art, when the wheel hub is produced, a corresponding one-dimensional code is often engraved on its surface. After the wheel hub is produced and during transportation, the one-dimensional code on the wheel hub can be read by a barcode reader to identify the corresponding wheel hub information.

[0004] However, when the wheel hub is being transported, the barcode reader may not be able to read the one-dimensional code clearly, which makes it impossible for the barcode reader to fully identify the one-dimensional code information on the wheel hub, which is not conducive to the daily production of the wheel hub. Utility Model Content

[0005] The present application provides a centering fixture, the purpose of which is to facilitate the barcode reader to read and identify the one-dimensional code on the wheel hub during transportation, thereby effectively ensuring the daily production of the wheel hub.

[0006] The present application provides a centering fixture, which adopts the following technical solution:

[0007] A centering fixture comprises a support frame, a support rod is fixed on the support frame, two sliders are installed on the support rod, the two sliders are slidably arranged in a direction of approaching or moving away from each other, a clamping shaft is provided on the top of the slider, and a plurality of rollers for transporting a wheel hub and a code reader for reading a one-dimensional code of the wheel hub are installed on the support frame.

[0008] The installation heights of the two sliding blocks are both lower than the installation height of the winding roller, and the top of the clamping shaft extends upward from the winding roller.

[0009] By adopting the above technical solution, in specific use, the wheel hub is transported by a roller after production is completed. When the wheel hub is transferred on the roller, it first gradually moves toward the direction close to the clamping shaft. While the wheel hub is being transported, the two sliders move toward each other. When the wheel hub is transferred to above the two sliders, the two sliders drive the corresponding clamping shafts to clamp the left and right ends of the wheel hub.

[0010] The wheel hub is disc-shaped as a whole, and the clamping shafts on the two sliders are distributed on the circumference of the wheel hub, which can effectively ensure the stability of the clamping shafts clamping the wheel hub.

[0011] In this setting, after the clamping shaft clamps the wheel hub, the one-dimensional code on the wheel hub is identified by the code reader, so that the code reader can quickly and efficiently identify the one-dimensional code information on the wheel hub, which is beneficial to ensure the daily processing and production of the wheel hub.

[0012] Preferably, a support platform is fastened above the support rod along its length direction, the slider is mounted on the support platform, and a cylinder is mounted at the bottom of the support platform, and the cylinder is used to drive the two sliders to slide.

[0013] By adopting the above technical solution, the slider is driven by the cylinder to slide on the support platform, and when the slider connected to the cylinder slides on the support platform, another slider is driven to slide synchronously.

[0014] Preferably, a connecting piece is provided between the two sliders, and the connecting piece includes a first rod body and two first rod bodies, the first rod body is rotatably mounted on the support platform, the two first rod bodies are respectively arranged between the first rod body and the two sliders, one end of the first rod body is hingedly connected to the slider, and the other end of the first rod body is hingedly connected to the end of the first rod body.

[0015] By adopting the above technical solution, when the cylinder drives one of the sliders to slide, the connecting piece can be used to synchronously drive the other slider to slide. This makes it possible to synchronously drive the two sliders to slide by installing only one cylinder at the bottom of the support platform, thereby effectively reducing the installation difficulty of the overall structure and making it more convenient to assemble.

[0016] Preferably, a hinged seat is installed on the top of the support platform, a rotating shaft is installed on the hinged seat along the vertical direction, and the first rod body is hingedly connected to the rotating shaft.

[0017] By adopting the above technical solution, the first rod body is rotatably mounted on the support platform by utilizing the hinge seat and the rotating shaft.

[0018] Preferably, two slide rails are fastened on the support platform along its length direction, and the two slide rails are spaced apart along the width direction of the support platform. Two slide seats are fastened on the bottom of the slider, and the two slide seats are slidably mounted on the two slide rails respectively.

[0019] By adopting the above technical solution, the slide seat and the slide rail can guide the sliding of the slider, thereby effectively ensuring the stability of the sliding process of the slider.

[0020] Preferably, the code reader is rotatably mounted on the support frame and is lifted and lowered in a vertical direction.

[0021] By adopting the above technical solution, since the wheel hub is in the shape of a disk and the one-dimensional code is engraved on its arc-shaped side wall, if the one-dimensional code is too long, it is inconvenient for the code reader to read it. The code reader can be rotated and installed on the support frame, and the angle of the code reader can be adjusted according to the length of the one-dimensional code, so that it is more convenient to use; the code reader is set to the lifting mode, and the height of the code reader can be adjusted according to the height of different wheel hubs.

[0022] Preferably, a motor is installed on the top of the support frame, the driving end of the motor faces downward and is connected to a turntable, a rotating arm is integrally formed in the horizontal direction on the side of the turntable away from the motor, a lifting module is installed in the vertical direction on the end of the rotating arm away from the turntable, and the code reader is installed at the bottom of the lifting module.

[0023] By adopting the above technical solution, when the angle of the code reader needs to be adjusted, the motor drives the turntable and the rotating arm to rotate synchronously, and the rotating arm drives the code reader to rotate while rotating; when the installation height of the code reader needs to be adjusted, the lifting module can be opened. The use of the rotating arm and the lifting module is conducive to improving the adaptability of the code reader and making it more convenient to use.

[0024] Preferably, the number of the clamping shafts on the slider is two, and the two clamping shafts are spaced apart and distributed at the left and right ends of the slider.

[0025] By adopting the above technical solution, the wheel hub is disc-shaped as a whole, and the number of clamping shafts on the slider is set to two. The clamping shafts on the two sliders can be distributed on the circumference of the wheel hub, which can effectively ensure the stability of the clamping shafts clamping the wheel hub.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] 1. In specific use, the wheel hub is transported by rollers after production. When the wheel hub is transferred on the roller, it first gradually moves toward the direction close to the clamping shaft. While the wheel hub is being transported, the two sliders move toward each other. When the wheel hub is transferred to the top of the two sliders, the two sliders drive the corresponding clamping shafts to clamp the left and right ends of the wheel hub.

[0028] The wheel hub is disc-shaped as a whole, and the clamping shafts on the two sliders are distributed on the circumference of the wheel hub, which can effectively ensure the stability of the clamping shafts clamping the wheel hub.

[0029] In this setting mode, after the clamping shaft clamps the wheel hub, the one-dimensional code on the wheel hub is identified by the code reader, so that the code reader can quickly and efficiently identify the one-dimensional code information on the wheel hub, which is beneficial to ensure the daily processing and production of the wheel hub;

[0030] 2. When the cylinder drives one of the sliders to slide, the connecting piece can synchronously drive the other slider to slide. This means that only one cylinder is installed at the bottom of the support platform to synchronously drive the two sliders to slide, thereby effectively reducing the installation difficulty of the overall structure and making it more convenient to assemble;

[0031] 3. When the angle of the code reader needs to be adjusted, the motor drives the turntable and the rotating arm to rotate synchronously, and the rotating arm drives the code reader to rotate at the same time; when the installation height of the code reader needs to be adjusted, the lifting module can be opened. The use of the rotating arm and the lifting module is conducive to improving the adaptability of the code reader and making it more convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0036] The following is combined with Figure 1 -Attached Figure 3 , further details of this application are given.

[0037] Example:

[0038] The present application embodiment discloses a centering fixture, referring to Figure 1 and Figure 2, including a support frame 1, which is composed of crisscross steel pipes and has a square frame structure as a whole. A support rod 2 is fixed to the support frame 1 in the horizontal direction by fastening bolts, and two sliders 3 are installed in the horizontal direction on the support rod 2, and the two sliders 3 are set to slide in the direction of approaching or moving away from each other. Two clamping shafts 4 are fastened to the top of the slider 3 by fastening bolts, and the clamping shafts 4 are vertically arranged, and the two clamping shafts 4 are spaced at the left and right ends of the slider 3. At the same time, a plurality of rollers 5 for transporting the wheel hub are installed in the horizontal direction on the support frame 1, and a motor is installed on the support frame 1, and a conveyor chain is connected to the driving end of the motor. The end of the roller 5 is connected to the conveyor chain, and the conveyor chain and the roller 5 are driven by the motor to rotate synchronously. The code reader 6 is installed on the support frame 1, and is used to read and identify the one-dimensional code on the wheel hub.

[0039] The installation heights of the two sliders 3 are both lower than the installation height of the winding roller 5 , and the top of the clamping shaft 4 extends upward from the winding roller 5 .

[0040] During specific use, the wheel hub is transported by the roller 5 after production is completed. When the wheel hub is transferred on the roller 5, it first gradually moves toward the direction close to the clamping shaft 4. While the wheel hub is being transported, the two sliders 3 move toward each other. When the wheel hub is transferred to the top of the two sliders 3, the two sliders 3 drive the corresponding clamping shafts 4 to clamp the left and right ends of the wheel hub.

[0041] The wheel hub is in the shape of a disk as a whole, and the clamping shafts 4 on the two sliding blocks 3 are distributed on the circumference of the wheel hub, which can effectively ensure the stability of the clamping shafts 4 clamping the wheel hub.

[0042] With this arrangement, after the clamping shaft 4 clamps the wheel hub, the one-dimensional code on the wheel hub is identified by the code reader 6, so that the code reader 6 can quickly and efficiently identify the one-dimensional code information on the wheel hub, which is beneficial to ensure the daily processing and production of the wheel hub.

[0043] An electric control cabinet and an operating table are installed on one side of the support frame 1. During specific operations, the clamp is controlled by the electric control cabinet and the operating table to perform operations.

[0044] In this embodiment, the code reader 6 is rotatably mounted on the support frame 1 and can be raised and lowered in the vertical direction.

[0045] Since the wheel hub is in the shape of a disk, and the one-dimensional code is engraved on its arc-shaped side wall, if the one-dimensional code is too long, it is inconvenient for the code reader 6 to read it. The code reader 6 can be rotatably mounted on the support frame 1, and the angle of the code reader 6 can be adjusted according to the length of the one-dimensional code, so that it is more convenient to use; the code reader 6 can be set to the lifting mode, and the height of the code reader 6 can be adjusted according to the height of different wheel hubs.

[0046] Specifically, refer to Figure 1 and Figure 2A motor is installed on the top of the support frame 1, with the driving end of the motor facing downward and connected to a disc-shaped turntable 14. A rotating arm 15 is integrally formed in the horizontal direction on the side of the turntable 14 away from the motor, and a lifting module 16 is installed in the vertical direction on the end of the rotating arm 15 away from the turntable 14, and the code reader 6 is installed at the bottom of the lifting module 16.

[0047] When the angle of the code reader 6 needs to be adjusted, the motor drives the turntable 14 and the rotating arm 15 to rotate synchronously, and the rotating arm 15 drives the code reader 6 to rotate while rotating; when the installation height of the code reader 6 needs to be adjusted, the lifting module 16 can be opened. The use of the rotating arm 15 and the lifting module 16 is conducive to improving the adaptability of the code reader 6 and making it more convenient to use.

[0048] Specifically, refer to Figure 1 and Figure 2 A support platform 7 is fastened to the top of the support rod 2 along its length direction by fastening bolts, and the slider 3 is installed on the support platform 7. A cylinder 8 is installed at the bottom of the support platform 7 along its length direction. The cylinder body of the cylinder 8 is fastened to the bottom of the support platform 7 by fastening bolts. The piston rod of the cylinder 8 is connected to one of the sliders 3 through a connecting block. The slider 3 is driven by the cylinder 8 to slide on the support platform 7. When the slider 3 connected to the cylinder 8 slides on the support platform 7, it synchronously drives the other slider 3 to slide.

[0049] Specifically, refer to Figure 2 and Figure 3 A connecting member 9 is provided between the two sliders 3, and the connecting member 9 includes a first rod 91 and two second rods 92. The first rod 91 and the two second rods 92 are both arranged horizontally, and the first rod 91 is rotatably mounted on the support platform 7, and the two second rods 92 are respectively arranged between the first rod 91 and the two sliders 3. One end of the second rod 92 is hingedly connected to the middle of the slider 3, and the other end of the second rod 92 is hingedly connected to the end of the first rod 91.

[0050] When the cylinder 8 drives one of the sliders 3 to slide, the connecting piece 9 can synchronously drive the other slider 3 to slide, which makes it possible to synchronously drive the two sliders 3 to slide by installing only one cylinder 8 at the bottom of the support platform 7, thereby effectively reducing the installation difficulty of the overall structure and making it more convenient to assemble.

[0051] Specifically, refer to Figure 2 and Figure 3 A hinge seat 10 is installed on the top of the support platform 7, and a rotating shaft 11 is installed on the hinge seat 10 in the vertical direction. The first rod body 91 is hingedly connected to the rotating shaft 11, and then the first rod body 91 is rotatably installed on the support platform 7 through the hinge seat 10 and the rotating shaft 11.

[0052] Further, refer to Figure 2 and Figure 3 Two slide rails 12 are fastened to the support platform 7 along its length direction by fastening bolts, and the two slide rails 12 are spaced apart along the width direction of the support platform 7. Two slide seats 13 are fastened to the bottom of the slider 3 by fastening bolts, and the two slide seats 13 are slidably mounted on the two slide rails 12 respectively. The slide seat 13 and the slide rail 12 can guide the sliding of the slider 3, thereby effectively ensuring the stability of the sliding process of the slider 3.

[0053] The implementation principle of a centering fixture in the embodiment of the present application is:

[0054] During specific use, the wheel hub is transported by the roller 5 after production is completed. When the wheel hub is transferred on the roller 5, it first gradually moves toward the direction close to the clamping shaft 4. While the wheel hub is being transported, the two sliders 3 move toward each other. When the wheel hub is transferred to the top of the two sliders 3, the two sliders 3 drive the corresponding clamping shafts 4 to clamp the left and right ends of the wheel hub.

[0055] The wheel hub is in the shape of a disk as a whole, and the clamping shafts 4 on the two sliding blocks 3 are distributed on the circumference of the wheel hub, which can effectively ensure the stability of the clamping shafts 4 clamping the wheel hub.

[0056] With this arrangement, after the clamping shaft 4 clamps the wheel hub, the one-dimensional code on the wheel hub is identified by the code reader 6, so that the code reader 6 can quickly and efficiently identify the one-dimensional code information on the wheel hub, which is beneficial to ensure the daily processing and production of the wheel hub.

[0057] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto.
