Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of pipe blank fixtures, and particularly relates to a tooling fixture for processing blanks. Background Technology
[0002] Pipelines, as an important component of industrial production, are widely used in various fields such as petroleum, natural gas, chemical, power, and water conservancy. The raw material for pipeline processing is the foundation material, and its quality directly affects the subsequent processing accuracy and finished product performance. Raw materials are typically made of metallic materials (such as carbon steel, stainless steel, and alloy steel) and formed through processes such as casting, forging, or rolling. Rough machining is the first step in processing pipeline raw materials. Its main purpose is to remove excess material from the surface of the raw material and initially form the shape and dimensions of the pipeline. The rough machining process for pipeline raw materials generally includes the following steps: selecting suitable raw material and performing preliminary dimensional inspection and surface cleaning; fixing the raw material on the processing equipment to ensure its stability during processing; performing preliminary machining of the outer diameter and inner hole of the raw material on a lathe to remove excess material; milling the end faces, flanges, and other parts of the raw material to initially form the required shape; and cleaning the surface of the machined raw material to remove burrs and oxide layers.
[0003] In the rough machining of pipe blanks, clamping and positioning are crucial for ensuring machining accuracy and efficiency. The function of the clamping and positioning structure is to firmly fix the blank on the machining equipment, keeping it stable during machining and preventing vibration, displacement, or deformation from affecting the machining quality. Especially in the rough machining stage, due to the large machining allowance and strong cutting forces, the stability of clamping and positioning directly affects the smooth progress of machining and the quality of the final product. However, existing tooling fixtures for pipe blanks are designed for specific shapes or sizes, lacking versatility.
[0004] Therefore, this utility model provides a tooling fixture for processing blanks to solve the problems existing in the prior art. Utility Model Content
[0005] To achieve the above objectives, this utility model provides the following solution: This utility model provides a tooling fixture for machining blanks, comprising:
[0006] A support base having a first through hole;
[0007] The displacement mechanism includes a lateral adjustment part, a radial adjustment part, and a drive adjustment part. The lateral adjustment part is fixedly connected to the support base, the radial adjustment part is fixedly connected to the output end of the drive adjustment part, the lateral adjustment part is rotatably connected to the drive adjustment part, and the radial adjustment part is fixedly connected to the lateral adjustment part through the first through hole.
[0008] The clamp structure is fixedly connected to the lateral adjustment part.
[0009] Furthermore, the lateral adjustment part includes a slider, a slide plate, and a slide rail. Several slide rails are provided on both sides of the support base. Several sliders are provided on each slide rail. Several sliders are slidably connected to the slide rails. The slide plate is fixedly connected to the sliders, and a second through hole is provided in the middle of the slide plate.
[0010] Furthermore, the drive adjustment unit includes a moving drive component and a lateral drive component, the moving drive component and the lateral drive component are respectively located on the two side walls of the support base, and are fixedly connected to the lateral adjustment unit and the radial adjustment unit of the moving mechanism.
[0011] Furthermore, the moving drive component includes a moving drive motor, a moving gear, and a rack. The output end of the moving drive motor passes through the second through hole into the cavity between the support base and the slide plate. The output end of the moving drive motor is fixedly connected to the moving gear, and the moving gear meshes with the rack.
[0012] Furthermore, the radial drive component includes a radial drive motor, a large drive gear, a small drive gear, a drive belt, and a drive roller. The output end of the radial drive motor passes through the second through hole into the cavity between the support base and the slide plate. The output end of the radial drive motor is fixedly connected to the large drive gear. The small drive gear is located on the drive roller. The large drive gear and the small drive gear are connected by the drive belt.
[0013] Furthermore, the radial adjustment part includes a transmission assembly, a telescopic arm, and a bearing. The transmission assembly is rotatably connected to the drive roller. The telescopic arm and the bearing are provided on the transmission assembly, and both the telescopic arm and the bearing are rotatably connected to the transmission assembly. The clamp structure is fixedly connected to the telescopic arm.
[0014] Furthermore, the transmission assembly includes a first bevel gear, a second bevel gear, and a fixed shaft. The first bevel gear is sleeved on the drive roller, and the second bevel gear is sleeved on the fixed shaft. The first bevel gear and the second bevel gear are meshed and connected. The fixed shaft is provided with threads, and the telescopic arm is sleeved on the fixed shaft.
[0015] Furthermore, the clamp structure includes a clamping plate and anti-slip components. The clamping plate is fixedly connected to the telescopic arm, and a plurality of anti-slip components are provided on the clamping plate.
[0016] Compared with the prior art, the beneficial effects of this utility model patent are as follows: This utility model patent uses a lateral adjustment part fixedly connected to the support base, and is independent of the radial adjustment structure, so that the axial position (along the length of the pipe) of the entire clamp can be freely adjusted to adapt to the needs of different processing areas of the pipe, without moving the heavy support base or affecting the clamping state. The radial adjustment part is controlled by the drive adjustment part and is used to adjust the clamping degree, ensuring that the application and release of clamping force are completely independent of the axial position of the clamp in the pipe, and the operation does not interfere with each other. The adjustment process is clearer and more controllable. The support base serves as a stable foundation, and the first through hole provides a connection point. The radial adjustment part is fixed to the output end of the drive adjustment part and is fixedly connected to the lateral adjustment part through the first through hole, ensuring that the force output by the drive adjustment part (used to open and close the clamp) can be efficiently and directly transmitted to the part of the clamp that performs the clamping action, reducing the possibility of deformation in the intermediate links. During rough machining, the clamp withstands the cutting reaction force and vibration from the inner wall of the pipe. The fixed support provides an axial support foundation for the fixture. Simultaneously, the clamping force generated by the radial adjustment unit is transmitted to the lateral adjustment unit and the support unit through a through-hole, forming a stable closed-loop structure. This resists radial forces and overturning moments during machining, preventing fixture displacement or loosening and ensuring machining accuracy. Separating the lateral and radial adjustments and controlling them with different components simplifies the operation logic. Operators can perform position positioning and clamping force adjustment separately and independently, eliminating the need for complex linkage operations, reducing the risk of misoperation, and improving adjustment speed and efficiency. The drive adjustment unit provides power to the radial adjustment unit, replacing laborious methods such as manual tightening, reducing the operator's workload. This is particularly evident in scenarios requiring frequent clamping force adjustments or clamping large pipes, where efficiency improvements are significant. The radial adjustment unit is specifically responsible for controlling the fixture's opening degree, enabling it to adapt to pipe blanks of different inner diameters. The drive adjustment unit allows for easy adjustment of the fixture's opening diameter, allowing it to abut against the inner walls of pipes of different sizes, expanding the fixture's applicability.

[0022] 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.
[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0024] See Figure 1-3 As shown, this embodiment provides a tooling fixture for processing blanks, including: a support base 1, on which a first through hole 101 is provided.
[0025] The displacement mechanism 2 includes a lateral adjustment part 201, a radial adjustment part 202, and a drive adjustment part 203. The lateral adjustment part 201 is fixedly connected to the support base 1, the radial adjustment part 202 is fixedly connected to the output end of the drive adjustment part 203, the lateral adjustment part 201 is rotatably connected to the drive adjustment part 203, and the radial adjustment part 202 is fixedly connected to the lateral adjustment part 201 through the first through hole 101.
[0026] The clamp structure 3 is fixedly connected to the lateral adjustment part 201.
[0027] Specifically, the support base 1 has a first through hole 101. The lateral adjustment part 201 and the radial adjustment part 202 are both located on the support base 1 and are fixedly connected through the first through hole 101. The drive adjustment part 203 is also located on the support base 1. The lateral adjustment part 201 and the radial adjustment part 202 can be adjusted by the drive adjustment part 203, that is, the lateral position and the opening degree of the clamp can be adjusted. That is, after the pipe blank 4 is placed, before rough machining, the position of the clamp is controlled by the lateral adjustment part 201, and then the opening degree of the radial adjustment part 202, i.e. the clamp, is controlled so that it can abut against the inner wall of the pipe blank 4, thereby enabling it to handle pipes of different diameters.
[0028] Understandably, the lateral adjustment unit 201 is dedicated to the axial positioning of the clamp, while the radial adjustment unit 202 independently controls the clamp's opening and closing degree. The two are physically connected through the first through-hole 101, but their functions do not interfere with each other. The operator can adjust the clamp's depth and fit against the inner wall of the pipe separately to avoid accidental operation due to linkage. The drive adjustment unit 203, as a single power source, simultaneously links lateral and radial movements through its output end, simplifying the operation process and ensuring the synchronous controllability of the two-dimensional adjustments.
[0029] In some embodiments of this application, the lateral adjustment part 201 includes a slider 2011, a slide plate 2012 and a slide rail 2013. Several slide rails 2013 are provided on both side walls of the support base 1. Several sliders 2011 are provided on each slide rail 2013. Several sliders 2011 are slidably connected to the slide rail 2013. The slide plate 2012 is fixedly connected to the sliders 2011, and a second through hole is provided in the middle of the slide plate 2012.
[0030] In some embodiments of this application, the drive adjustment unit 203 includes a moving drive component and a radial drive component, which are located on the two side walls of the support base 1 and are fixedly connected to the radial adjustment unit 202.
[0031] Specifically, when it is necessary to adjust the lateral position of the fixture, the slider 2011 and the slide plate 2012 are driven to move on the slide rail 2013 by the lateral drive motor, thereby achieving the effect of adjusting the lateral position.
[0032] In some embodiments of this application, the moving drive component includes a moving drive motor 2031, a moving gear 2032, and a rack 2033. The output end of the moving drive motor 2031 passes through the second through hole into the cavity between the support base 1 and the slide plate 2012. The output end of the moving drive motor 2031 is fixedly connected to the moving gear 2032, and the moving gear 2032 meshes with the rack 2033.
[0033] In some embodiments of this application, the radial drive component includes a radial drive motor 2034, a large drive gear 2035, a small drive gear 2036, a drive belt 2037, and a drive roller 2038. The output end of the radial drive motor passes through the second through hole into the cavity between the support base 1 and the slide plate 2012. The output end of the radial drive motor is fixedly connected to the large drive gear 2035. The small drive gear 2036 is located on the drive roller 2038. The large drive gear 2035 and the small drive gear 2036 are connected by the drive belt 2037.
[0034] Specifically, the rotation of the moving drive motor 2031 causes the moving gear 2032 to move on the rack 2033, which in turn causes the slide plate 2012 and the slider 2011 to move on the slide rail 2013, thereby achieving the effect of controlling the lateral displacement of the fixture. The radial drive component drives the large drive gear 2035 to rotate through the radial drive motor 2034, which in turn drives the small drive gear 2036 to rotate through the drive belt 2037, thereby achieving the effect of rotating the drive roller 2038.
[0035] In some embodiments of this application, the radial adjustment part 202 includes a transmission assembly, a telescopic arm 2023 and a bearing 2024. The transmission assembly is rotatably connected to the drive roller 2038. The transmission assembly is provided with the telescopic arm 2023 and the bearing 2024, and both the telescopic arm 2023 and the bearing 2024 are rotatably connected to the transmission assembly. A clamp structure 3 is fixedly connected to the telescopic arm 2023.
[0036] In some embodiments of this application, the transmission assembly includes a first bevel gear 2021, a second bevel gear 2022, and a fixed shaft 2025. The first bevel gear 2021 is sleeved on the drive roller 2038, and the second bevel gear 2022 is sleeved on the fixed shaft 2025. The first bevel gear 2021 and the second bevel gear 2022 are meshed and connected. The fixed shaft 2025 is provided with threads, and the telescopic arm 2023 is sleeved on the fixed shaft 2025.
[0037] In some embodiments of this application, the clamp structure 3 includes a clamping plate 301 and anti-slip elements 302. The clamping plate 301 is fixedly connected to the telescopic arm 2023, and a plurality of anti-slip elements 302 are provided on the clamping plate 301.
[0038] Specifically, when the drive roller 2038 rotates, the first bevel gear 2021 on the drive roller 2038 rotates, which in turn drives the second bevel gear 2022 to rotate, which in turn drives the fixed shaft 2025 to rotate. The bearing 2024 is fixedly connected to the fixed frame 2026, and the fixed shaft 2025 is provided with threads. When the fixed shaft 2025 rotates, the threads rotate, which in turn controls the telescopic arm 2023 to achieve the telescopic effect, thereby enabling the clamping plate 301 to open and close, so that the clamping plate 301 abuts against the inner wall of the pipe blank 4. The clamping plate 301 is provided with anti-slip parts 302 to further suppress the displacement of the pipe blank 4.
[0039] In the above embodiments, a tooling fixture for processing a blank is fixedly connected to the support base 1 via a lateral adjustment part 201, and is independent of the radial adjustment structure. This allows the axial (along the pipe length) position of the fixture as a whole to be freely adjusted to adapt to the needs of different processing areas of the pipe without moving the heavy support base or affecting the clamping state. The radial adjustment part 202 is controlled by a drive adjustment part 203 to adjust the clamping degree, ensuring that the application and release of clamping force are completely independent of the axial position of the fixture within the pipe, and the operations are independent of each other. Interference is reduced, and the adjustment process becomes clearer and more controllable. The support base 1 serves as a stable foundation, and the first through hole 101 provides a connection point. The radial adjustment part 202 is fixed to the output end of the drive adjustment part 203, and is also fixedly connected to the lateral adjustment part 201 through the first through hole 101. This ensures that the force output by the drive adjustment part 203 (used for opening and closing the clamp) can be efficiently and directly transmitted to the clamping part, reducing the possibility of deformation in intermediate links. During rough machining, the clamp withstands the cutting reaction force and vibration from the inner wall of the pipe. The lateral adjustment part 201 and... The support base 1 is fixed, providing an axial support foundation for the fixture. At the same time, the clamping force generated by the radial adjustment part 202 is transmitted to the lateral adjustment part 201 and the support base 1 through the through hole, forming a stable closed-loop structure to resist radial forces and overturning torques during processing, prevent fixture displacement or loosening, and ensure processing accuracy. Separating the lateral adjustment and radial adjustment and controlling them by different components simplifies the operation logic. The operator can perform position positioning and clamping force adjustment separately and independently without complex linkage operations, reducing the risk of misoperation and improving adjustment speed and efficiency. The drive adjustment part 203 provides power to the radial adjustment part 202, replacing laborious methods such as manual tightening, reducing the operator's labor intensity. The efficiency improvement is particularly significant for scenarios that require frequent adjustment of clamping force or clamping large pipes. The radial adjustment part 202 is specifically responsible for controlling the clamp opening degree, enabling it to adapt to pipe blanks 4 with different inner diameters. By driving the adjustment part 203, the opening diameter of the fixture can be easily adjusted so that it abuts against the inner wall of pipes of different sizes, expanding the applicability of the fixture.
[0040] Operating process: First, the pipe blank 4 is placed in a fixed position. Then, the moving drive motor 2031 rotates, driving the moving gear 2032 to move on the rack 2033, thereby controlling the slide plate 2012 and the slider 2011 to move on the slide rail 2013, controlling the displacement of the clamping plate 301, so that it is initially aligned with the pipe blank 4. Then, the radial drive motor 2034 rotates, driving the large drive gear 2035 to rotate, and then the drive belt 2037 drives the small drive gear 2036 to rotate, thereby driving the drive roller 2038 to rotate. At this time, the first bevel gear 2021 rotates, driving the second bevel gear 2022 to rotate, thereby driving the fixed shaft 2025 to rotate, thereby controlling the opening and closing degree of the telescopic arm 2023, and thus controlling the clamping plate 301 to abut against the inner wall of the pipe blank 4.
