Description

Technical Field

[0001] This utility model relates to the technical field of rotary body processing equipment, and in particular to a heavy-duty rotary body indexing processing fixture. Background Technology

[0002] Heavy-duty rotating bodies refer to components in mechanical equipment that bear large loads and are capable of rotating around a fixed axis. These components are typically designed for use in heavy industrial machinery, such as cranes, large machine tools, wind turbines, and port machinery.

[0003] Machining fixtures are auxiliary tools or equipment used in the machining of heavy rotating bodies. They are mainly used to fix, position, and support the workpiece to ensure the accuracy of its position and the stability of the machining process. The design and selection of machining fixtures directly affect the machining quality and efficiency.

[0004] A precision machining fixture for rotating bodies is disclosed in Chinese Patent Publication No. CN221111468U. This precision machining fixture for rotating bodies is suitable for fixing rotating parts of different lengths and diameters, which improves its applicability. The rubber anti-slip pad can not only increase the friction between the clamping plate and the rotating part, preventing the rotating part from rotating during the machining process, but also prevent the clamping plate from causing wear on the rotating part.

[0005] However, compared with existing technologies in related fields, when processing rotating bodies of different models (diameters), existing devices are neither convenient for the rapid placement of rotating bodies nor for rapid adjustment and adaptation, resulting in a cumbersome and inconvenient adjustment process when processing rotating bodies of different models (diameters). Utility Model Content

[0006] The purpose of this utility model is to overcome the shortcomings of the prior art, solve the problems mentioned in the background art, and provide a heavy-duty rotary indexing machining fixture.

[0007] The purpose of this utility model is achieved through the following technical solution: a heavy-duty rotary indexing machining fixture, including a worktable, with multiple clamping fixtures on the top of the worktable for supporting the rotary body. The clamping fixtures include a mounting box fixedly installed on the top of the worktable. Inside the mounting box, two inclined supports and two sliders are symmetrically slidably arranged. The two inclined supports cooperate to support the rotary body. The mounting box is provided with an adjustment component for controlling the two inclined supports and the two sliders to move closer or further apart. A backing plate is fixedly installed on the mounting box corresponding to the position of the two sliders. A pressing member is rotatably provided on the two backing plates through a rotating shaft. The two pressing members cooperate to limit the rotary body. The sliders and the pressing members are connected by a hinge component. When the two sliders move closer together, the ends of the two pressing members move away from each other. When the two sliders move away from each other, the ends of the two pressing members move closer together.

[0008] Preferably, the adjustment assembly includes a first screw and a second screw rotatably disposed inside the mounting box. Both the first screw and the second screw are left- or right-hand threaded rods. Both inclined supports are threadedly connected to the first screw, and both sliders are threadedly connected to the second screw. Synchronous gears are fixedly installed at the middle of both the first screw and the second screw, and the two synchronous gears mesh with each other. A motor is fixedly installed on the side of the mounting box, and the output end of the motor is connected to the end of the second screw.

[0009] Preferably, the mounting box has rotating holes at both ends corresponding to the first and second screws, and the first and second screws are connected to the rotating holes through bearings.

[0010] Preferably, the inclined surfaces of the inclined supports all face the synchronous gear, and the inclined surfaces of the inclined supports are rotatably provided with multiple first rollers.

[0011] Preferably, the pressing component is L-shaped, and a second roller is rotatably provided at the end of the pressing component away from the slider.

[0012] Preferably, the hinge assembly includes a fixing member fixedly installed on the top of the slider, an adjusting shaft fixedly provided on the side of the fixing member away from the slider, the first roller, the second roller and the adjusting shaft are all arranged along the direction of the clamping fixture array, the pressing member has a movable groove at the position corresponding to the fixing member, and the pressing member has adjusting grooves at both ends corresponding to the adjusting shaft.

[0013] Beneficial effects:

[0014] This heavy-duty rotary indexing machining fixture, by setting up clamping fixtures, adjustment components and hinge components, achieves the purpose of quickly placing the rotary body before machining, thereby improving the convenience of rotary body machining. At the same time, it can be quickly adjusted according to the model or diameter of the rotary body, so that the pressing part and the inclined support cooperate with each other to position the rotary body, ensuring the stability of the rotary body during machining, and at the same time, it can improve the applicability of the device.

Detailed Implementation

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] Additional aspects and advantages of this invention will be further set forth in the description which follows in conjunction with the accompanying drawings, and in part will be obvious from the description or may be learned by practice of the invention.

[0025] like Figures 1 to 6 As shown, a heavy-duty rotary indexing machining fixture includes a worktable 1. Multiple clamping fixtures 2 for supporting the rotary body are provided on the top of the worktable 1. Each clamping fixture 2 includes a mounting box 21 fixedly installed on the top of the worktable 1. Two inclined supports 22 and two sliders 23 are symmetrically slidably arranged inside the mounting box 21. The two inclined supports 22 cooperate to support the rotary body. An adjustment component 3 is provided on the mounting box 21 to control the two inclined supports 22 and the two sliders 23 to move closer or further apart. A backing plate 24 is fixedly installed on the mounting box 21 at the position corresponding to the two sliders 23. A pressing member 25 is rotatably mounted on each of the two backing plates 24 via a rotating shaft. The two pressing members 25 cooperate to limit the rotation of the rotary body. The sliders 23 and the pressing members 25 are connected by a hinge component 4. When the two sliders 23 move closer together, the ends of the two pressing members 25 move further apart; when the two sliders 23 move further apart, the ends of the two pressing members 25 move closer together.

[0026] As a preferred embodiment of this invention, the adjusting assembly 3 includes a first screw 31 and a second screw 32 rotatably disposed inside the mounting box 21. Both the first screw 31 and the second screw 32 are left- or right-hand threaded rods. Two inclined supports 22 are threadedly connected to the first screw 31, and two sliders 23 are threadedly connected to the second screw 32. Synchronous gears 33 are fixedly installed at the middle of both the first screw 31 and the second screw 32, and the two synchronous gears 33 mesh with each other. A motor 34 is fixedly installed on the side of the mounting box 21, and the output end of the motor 34 is connected to the end of the second screw 32. The above embodiment describes the specific structure and connection relationship of the adjusting assembly 3, thereby controlling the rotation of the second screw 32 through the motor 34. Then, through the cooperation of two synchronous gears 33, the first screw 31 rotates in the opposite direction at the same speed, thereby causing the two inclined supports 22 to move away from each other and the two sliders 23 to move closer together. At this time, the hinge assembly 4 can be used to make the ends of the two pressing parts 25 move away from each other. The motor 34 controls the second screw 32 to rotate in the opposite direction, and then through the cooperation of two synchronous gears 33, the first screw 31 rotates in the other direction at the same speed, thereby causing the two inclined supports 22 to move closer together and the two sliders 23 to move away from each other. At this time, the hinge assembly 4 can be used to make the ends of the two pressing parts 25 move closer together. The motor 34 described in this application is known technology, so its working principle and specific structure are not described in detail.

[0027] As a preferred technical solution of this utility model, the mounting box 21 has rotating holes at both ends corresponding to the first screw 31 and the second screw 32. The first screw 31 and the second screw 32 are connected to the rotating holes through bearings. By using the bearings, the friction force when the first screw 31 and the second screw 32 rotate can be reduced, and the stability of the first screw 31 and the second screw 32 when rotating can be improved.

[0028] As a preferred technical solution of this utility model, the inclined surfaces of the inclined support 22 all face the synchronous gear 33, and the inclined surfaces of the inclined support 22 are rotatably provided with a plurality of first rollers 221. The pressing member 25 is L-shaped, and the end of the pressing member 25 away from the slider 23 is rotatably provided with a second roller 251. Through the provided first rollers 221 and second rollers 251, the first rollers 221 on the inclined support 22 can support the rotating body, and the end of the pressing member 25 abuts against the rotating body, thereby reducing the friction force when the rotating body rotates and improving the stability of the rotating body during rotation processing.

[0029] As a preferred technical solution of this utility model, the hinge assembly 4 includes a fixing member 41 fixedly installed on the top of the slider 23. An adjusting shaft 42 is fixedly provided on the side of the fixing member 41 away from the slider 23. The first roller 221, the second roller 251 and the adjusting shaft 42 are all arranged along the direction of the clamping fixture 2 array. The pressing member 25 has a movable groove 252 at the position corresponding to the fixing member 41. The pressing member 25 has adjusting grooves 253 at both ends corresponding to the adjusting shaft 42. By setting the adjusting shaft 42 and the adjusting grooves 253, when the two sliders 23 are close to each other, the ends of the two pressing members 25 can be moved away from each other. When the sliders 23 are moved away from each other, the ends of the two pressing members 25 can be moved closer to each other. This makes it easy to place the rotating body between the two pressing members 25 on the two inclined supports 22. At the same time, the mutual cooperation between the pressing member 25 and the inclined support 22 can be used to position the rotating body and ensure the stability of the rotating body during processing.

[0030] The work process is as follows:

[0031] S1, such as Figures 1 to 5 As shown, in use, the second screw 32 is first rotated by the motor 34, and then the first screw 31 is rotated in the opposite direction at the same speed by the cooperation of two synchronous gears 33, thereby causing the two inclined supports 22 to move away from each other and the two sliders 23 to move closer to each other, as shown. Figure 6 As shown, the hinge assembly 4 allows the ends of the two pressing members 25 to move away from each other.

[0032] S2, such as Figures 1 to 5 As shown, when the ends of the two pressing parts 25 are far apart, the rotating body can be placed directly between the two pressing parts 25 on the two inclined supports 22, at which time the two inclined supports 22 will support the rotating body.

[0033] S3, such as Figures 1 to 5 As shown, after the rotating body is placed, the second screw 32 is controlled to rotate in the opposite direction by the motor 34. Then, through the cooperation of two synchronous gears 33, the first screw 31 rotates in the opposite direction at the same speed, thereby causing the two inclined supports 22 to move closer to each other and the two sliders 23 to move away from each other, as shown. Figure 6 As shown, the hinge assembly 4 allows the ends of the two pressing members 25 to approach each other.

[0034] S4, such as Figures 1 to 5 As shown, by bringing the two inclined supports 22 close to each other, the inclined supports 22 can lift the rotating body. By bringing the ends of the two pressing members 25 close to each other, the second roller 251 of the pressing member 25 can abut against the outer surface of the rotating body (that is, the upper half of the rotating body when it is not rotating). At this time, the positioning step of the rotating body is completed.

[0035] S5. Once the rotating body is positioned, it can be processed.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
