Description

Technical Field

[0001] This utility model relates to the technical field of cutting and indexing devices, specifically a wheel hub blank equal-division cutting and indexing device. Background Technology

[0002] During the processing of wheel hub blanks, the original columnar raw material needs to be cut into equal parts so that it can be cut into the original shape of the wheel hub, which facilitates further processing of the wheel hub.

[0003] In practical applications, the existing cutting and indexing devices have relatively complete structures and functions, and can basically meet daily usage needs. However, the following problems still exist: In practical use, the common practice is to draw equal division lines on the cylindrical material with a marker pen and use a push-in structure to push the division lines on the cylindrical material to the designated position. However, this method requires manual calibration of the position of the division lines and the cutting blade. Moreover, there is already an objective error when drawing the division lines. After manual calibration, another objective error occurs. The cumulative error increases the overall error and thus affects the division effect.

[0004] Therefore, this utility model provides a wheel hub blank equal division cutting indexing device. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a wheel hub blank equal division cutting indexing device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a wheel hub blank equal division cutting indexing device, including a base, wherein the base has a rectangular structure; Mounting frame, which is fixedly connected to the top of the base; A first conveyor belt is installed inside the mounting frame; The equal-division feeding assembly is disposed on one side of the base. The equal-division feeding assembly includes a support base, one side of which is fixedly connected to one side of the base. A U-shaped frame is fixedly connected to the top of the support base. A second conveyor belt is installed on the inner wall of the U-shaped frame. A scale plate is fixedly connected to the top of the U-shaped frame. A limiting component is provided on one side of the base. The limiting component includes a limiting plate. A plurality of wheel grooves are provided on one side of the limiting plate. Guide rollers are rotatably provided on the inner wall of the wheel grooves. A cutting assembly is disposed at the connection between the base and the support.

[0007] With the help of the equal-division guide component and other components such as the scale plate, the cylindrical material moves to the appropriate position, and there is no need to mark the equal division line for alignment, which reduces the overall error. With the help of the limiting component, the cylindrical material on the first conveyor belt is limited on both sides to prevent the cylindrical material from shifting position on the first conveyor belt.

[0008] Optionally, a guide plate is fixedly connected to one side of the U-shaped frame, and rectangular baffles are fixedly connected to both sides of the guide plate.

[0009] After the cylindrical raw material is cut, the guide plate moves along the second conveyor belt to the guide plate to facilitate guidance to the designated collection position. The rectangular baffle prevents the cylindrical raw material from separating from the guide plate from both sides.

[0010] Optionally, a first rectangular frame is fixedly connected to one side of the U-shaped frame, a first motor is installed on one side of the first rectangular frame, a first screw is fixedly connected to the output end of the first motor, a first screw hole block is threadedly connected to the outer surface of the first screw, a first connecting rod is fixedly connected to the top of the first screw hole block, a first rectangular through hole is opened at the top of the first rectangular frame, the first connecting rod is slidably disposed on the inner wall of the first rectangular through hole, and a positioning baffle is fixedly connected to one end of the first connecting rod.

[0011] The first screw drives the first screw hole block to move, which in turn causes the first connecting rod to move the positioning baffle. In conjunction with the scale plate, the positioning baffle moves to the appropriate position. During the equal division cutting, the positioning baffle is positioned so that one end of the cylindrical material abuts against the positioning baffle.

[0012] Optionally, a second rectangular frame is fixedly connected to one side of the base, a second motor is installed on one side of the second rectangular frame, a second screw is fixedly connected to the output end of the second motor, the two ends of the second screw have opposite thread directions, two second screw hole blocks are symmetrically threaded on the outer surface of the second screw, a second connecting rod is fixedly connected to one side of the second screw hole block, and one end of the second connecting rod is fixedly connected to one side of the limiting plate.

[0013] The second screw drives the second screw hole block to move, which allows the second connecting rod to drive the two limiting plates to move downwards or in opposite directions, thus limiting the cylindrical raw materials of different sizes.

[0014] Optionally, a second rectangular through hole is provided at the top of the second rectangular frame, and a limiting slide rod is fixedly connected to the top of the second screw hole block. The limiting slide rod is slidably disposed on the inner wall of the second rectangular through hole.

[0015] The limiting slide bar limits the second screw hole block, causing the second screw hole block to move along the outer surface of the second screw.

[0016] Optionally, the cutting assembly includes a U-shaped frame, which is fixedly connected to one side of a U-shaped frame. A first hydraulic telescopic rod is installed on the top of the U-shaped frame. An L-shaped plate is fixedly connected to the output end of the first hydraulic telescopic rod. A third motor is installed on one side of the L-shaped plate. A rotating rod is fixedly connected to the output end of the third motor. A cutting blade is fixedly connected to one end of the rotating rod.

[0017] The first hydraulic telescopic rod drives the L-shaped plate to move, which in turn drives the cutting blade to move up and down. This, in conjunction with the third motor, drives the cutting blade to rotate, facilitating the cutting of cylindrical raw materials.

[0018] Optionally, an auxiliary plate is fixedly connected to one side of the U-shaped frame, and a second hydraulic telescopic rod is installed on the top of the auxiliary plate. A fixing block is fixedly connected to the output end of the second hydraulic telescopic rod.

[0019] The second hydraulic telescopic rod drives the fixed pressure block to move up and down, so that the fixed pressure block presses and limits the top of the cylindrical material, preventing it from moving during cutting.

[0020] This utility model provides a wheel hub blank equal-division cutting and indexing device. It has the following beneficial effects: By setting up equal-division guiding components and limiting components, the equal-division guiding components adjust the position of the positioning baffle so that one end of the cylindrical material abuts against the positioning baffle, thereby limiting one end of the cylindrical material. At this time, the distance between the positioning baffle and the cutting blade is the equal-division cutting length. This process can be completed by adjusting the equal-division length once. Moreover, during the alignment process, it is only necessary to make one end of the cylindrical material abut against the positioning baffle, eliminating the need for manual alignment and reducing overall errors. The limiting components limit the cylindrical material on both sides during transportation on the second conveyor belt to prevent slippage on the second conveyor belt.

[0021] By setting up a cutting component, the top of the cylindrical material is limited by a fixed pressure block during the cutting process, preventing the cylindrical material from shifting its position during the cutting process. Attached Figure Description

[0024] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1-5As shown, this embodiment provides a technical solution: a wheel hub blank equal-division cutting and indexing device, including a base 1, a mounting frame 2, a first conveyor belt 3, an equal-division guiding component 4, a limiting component 5, and a cutting component 6. The base 1 has a rectangular structure, providing stable support for the entire device. It is made of high-strength alloy steel to ensure a load-bearing capacity of not less than 500 kg. The surface is treated with anti-rust treatment, such as galvanizing or spraying with anti-rust paint, and has a service life of not less than 5 years. The mounting frame 2 is fixedly connected to the top of the base 1 by welding or high-strength bolts. The frame is made of rectangular steel pipe welded together, and the inner wall flatness error does not exceed ±0.5 mm. It is used to fix the first conveyor belt 3. The first conveyor belt 3 is installed inside the mounting frame 2 and is made of wear-resistant rubber. The bandwidth is adapted to the diameter of the wheel hub blank and can be designed to be 300-500 mm according to actual needs. The conveying speed is adjustable from 0.5-2 m / min and is used to transport the wheel hub blank to be cut to the subsequent processing station. The equal-division guiding component 4 is located on one side of the base 1. Its core function is to equally divide and guide the wheel hub blank, ensuring accurate positioning when entering the cutting station. This component includes a support base 41, a U-shaped frame 42, a second conveyor belt 43, and a scale plate 45. One side of the support base 41 is fixedly connected to one side of the base 1 by bolts, and the top of the support base 41 is welded to the U-shaped frame 42. The second conveyor belt 43 is installed on the inner wall of the U-shaped frame 42. The second conveyor belt 43 conveys in the same direction as the first conveyor belt 3 and maintains synchronized speed to prevent the cylindrical material from shifting during transportation. The scale plate 45 is fixedly connected to the top of the U-shaped frame 42. The scale accuracy is 1mm, which is used to visually observe the guiding position of the cylindrical material, facilitating manual calibration or automated positioning adjustment. The limiting component 5 is located on one side of the base 1 to laterally limit the cylindrical material and prevent shaking during cutting. The component includes a limiting plate 56, on one side of which are several wheel grooves 59. Guide rollers 510 are rotatably mounted on the inner wall of each wheel groove 59. The guide rollers 510 are made of wear-resistant nylon with a smooth, burr-free surface, reducing frictional damage to the cylindrical raw material. The cutting component 6 is located at the connection between the base 1 and the support 41. It is the core processing component of the device, used to achieve equal-segment cutting of the wheel hub blank, with a cutting accuracy error not exceeding ±0.1mm.

[0026] The equal-division guide assembly 4 reduces the division error when the cylindrical raw material is cut into equal parts, and moves the wheel hub blank to the designated position after cutting. The limiting assembly 5 limits the cylindrical raw material on both sides of the first conveyor belt 3. At the same time, the cutting assembly 6 fixes and limits the cylindrical raw material during cutting.

[0027] like Figure 2As shown, a guide plate 44 is fixedly connected to one side of the U-shaped frame 42. The guide plate 44 has an angle of 15°-30° with the horizontal plane, which facilitates the smooth transition of the wheel hub blank from the first conveyor belt 3 to the second conveyor belt 43. Rectangular baffles are fixedly connected to both sides of the guide plate 44. The baffles are 50-80mm high, which can prevent the wheel hub blank from slipping off the sides during the transition.

[0028] like Figure 2 and Figure 3 As shown, a first rectangular frame 46 is fixedly connected to one side of the U-shaped frame 42. The first rectangular frame 46 is made of aluminum alloy, which is lightweight and has high strength. A first motor 47 is bolted to one side of the first rectangular frame 46. The first motor 47 is a servo motor with a rated power of 0.5-1kW and a speed adjustment range of 0-1500r / min, which can achieve precise speed adjustment. The output end of the first motor 47 is fixedly connected to a first screw 48 through a coupling. The first screw 48 adopts a ball screw structure with a precision grade of C7 and a lead of 5-10mm. A first screw hole block 49 is threadedly connected to the outer surface of the first screw 48. The top of the first screw hole block 49 is fixedly connected to... A first connecting rod 411 is connected, which is a cylindrical structure with a diameter of 10-15mm. A first rectangular through hole 410 is opened at the top of the first rectangular frame 46. The width of the through hole is 1-2mm larger than the diameter of the first connecting rod 411 to ensure that the first connecting rod 411 can slide smoothly. The first connecting rod 411 is slidably set on the inner wall of the first rectangular through hole 410. A positioning baffle 412 is fixedly connected to one end of the first connecting rod 411. The positioning baffle 412 is an arc-shaped structure, and its curvature is adapted to the outer circle of the wheel hub blank. The first screw 48 can be driven to rotate by the first motor 47, which drives the positioning baffle 412 to move left and right to realize the positioning adjustment of wheel hub blanks with different cutting lengths.

[0029] like Figure 1 , Figure 3 and Figure 4As shown, a second rectangular frame 51 is fixedly connected to one side of the base 1. The second rectangular frame 51 is made of the same material as the first rectangular frame 46, both being aluminum alloy. A second motor 52 is installed on one side of the second rectangular frame 51. The second motor 52 is also a servo motor with a rated power of 0.5-1kW, matching the model of the first motor 47 for easy synchronous control. The output end of the second motor 52 is fixedly connected to a second screw 53 via a coupling. The second screw 53 is a bidirectional ball screw with a precision grade of C7, with opposite thread directions at both ends and a lead of 5-10mm. The outer surface of the screw 53 is symmetrically threaded with two second screw hole blocks 54. The two second screw hole blocks 54 can move synchronously in opposite directions or in the opposite direction under the drive of the second motor 52. A second connecting rod 55 is fixedly connected to one side of the second screw hole block 54. The diameter of the second connecting rod 55 is the same as that of the first connecting rod 411, which is 10-15mm. One end of the second connecting rod 55 is welded and fixed to one side of the limiting plate 56. Driven by the second motor 52, the distance between the two limiting plates 56 can be adjusted to adapt to wheel hub blanks of different diameters with a range of 150-400mm.

[0030] like Figure 4 As shown, the top of the second rectangular frame 51 is provided with a second rectangular through hole 57, the width of which is 1-2 mm larger than the diameter of the limiting slide rod 58; the top of the second screw hole block 54 is fixedly connected to the limiting slide rod 58, which is parallel to the second connecting rod 55 and has a diameter of 8-12 mm; the limiting slide rod 58 is slidably disposed on the inner wall of the second rectangular through hole 57, which can guide and limit the movement of the second screw hole block 54, prevent the second screw hole block 54 from rotating with the second screw 53, and ensure that the limiting plate 56 only moves in a straight line.

[0031] like Figure 1 , Figure 2 and Figure 5As shown, the cutting assembly 6 includes a U-shaped frame 61, which is bolted to one side of the U-shaped frame 42. The U-shaped frame 61 is made of high-strength steel and has a load-bearing capacity of not less than 200 kg. A first hydraulic telescopic rod 62 is installed on the top of the U-shaped frame 61. The rated pressure of the first hydraulic telescopic rod 62 is 5-10 MPa, and the telescopic stroke is 100-200 mm. It can drive the cutting blade 66 to move up and down to adjust the cutting depth. An L-shaped plate 63 is fixedly connected to the output end of the first hydraulic telescopic rod 62. The L-shaped plate 63 is made of steel plate bent and formed, and the surface is quenched to a hardness of HRC40-45. A third motor 64 is installed on one side. The third motor 64 is a high-speed motor with a rated power of 1.5-3kW and a speed of 10000-15000r / min, ensuring that the cutting blade 66 has sufficient cutting speed. The output end of the third motor 64 is fixedly connected to a rotating rod 65 through a flange. The rotating rod 65 is made of alloy steel and has a diameter of 20-30mm. One end of the rotating rod 65 is fixedly connected to the cutting blade 66. The cutting blade 66 is a diamond saw blade with a diameter of 200-300mm and a thickness of 2-3mm, which can achieve efficient cutting of cylindrical materials, and the blade has a service life of no less than 500 cutting operations.

[0032] like Figure 5 As shown, an auxiliary plate 67 is fixedly connected to one side of the U-shaped frame 61. The auxiliary plate 67 is perpendicular to the U-shaped frame 61 and is made of steel plate. A second hydraulic telescopic rod 68 is installed on the top of the auxiliary plate 67. The second hydraulic telescopic rod 68 has the same parameters as the first hydraulic telescopic rod 62, with a rated pressure of 5-10MPa and a telescopic stroke of 100-200mm. It can move synchronously with the first hydraulic telescopic rod 62. A fixing block 69 is fixedly connected to the output end of the second hydraulic telescopic rod 68. It can press and fix the cylindrical raw material before cutting to prevent displacement during the cutting process.

[0033] Working principle: like Figure 1-5 As shown: When in use, the second motor 52 is started, which causes the second screw 53 to drive the second screw hole block 54 to move, which in turn drives the second connecting rod 55 and the limiting plate 56 to move, thereby limiting the two sides of the cylindrical raw material. Start the first motor 47, which drives the first screw 48 to move, which in turn drives the first screw hole block 48 to move, which in turn drives the first screw hole block 49 to move the first connecting rod 411, which in turn drives the positioning baffle 412 to move. Under the action of the first conveyor belt 3, the cylindrical raw material is driven to move, so that one end of it abuts against the positioning baffle 412. At this time, the second hydraulic telescopic rod 68 is activated, so that the fixed pressure block 69 fixes the top of the cylindrical raw material. At this time, the first hydraulic telescopic rod 61 is activated, which causes the L-shaped plate 63 to drive the cutting blade 66 to move. The third motor 64 is activated, which causes the rotating rod 65 to drive the cutting blade 66 to rotate, thereby cutting the cylindrical raw material. After cutting, the second conveyor belt 43 is started, so that the wheel hub blank is guided from the guide plate 44 to the designated collection position.
