Description

Technical Field

[0001] This application relates to the field of fixture technology, specifically a multi-directional adjustable fixture debugging platform. Background Technology

[0002] In modern mechanical manufacturing, automotive welding, aerospace assembly, and precision component inspection, workpieces must be stably and precisely fixed in specific positions during processing, welding, assembly, or inspection to ensure process quality and product consistency. Traditionally, this function is usually achieved by dedicated fixtures. These dedicated fixtures are designed for specific workpiece models and have the advantages of high positioning accuracy and high clamping efficiency. However, as the manufacturing industry develops towards multi-variety, small-batch, and fast-paced production, and as the iteration cycle of new product development continues to shorten, the inherent drawbacks of dedicated fixtures are becoming increasingly apparent: their rigid and fixed structure lacks adaptability. Once the product model changes or process adjustments are required, the original fixtures are often unsuitable, necessitating redesign, manufacturing, and adjustment, leading to extended production preparation cycles and significantly increased costs. Summary of the Invention

[0003] The technical problem to be solved by this application is to overcome the existing defects and provide a multi-directional adjustable fixture debugging platform, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, this application provides the following technical solution: a multi-directional adjustment fixture debugging platform, comprising:

[0005] Platform base;

[0006] A center positioning component is disposed at both ends of the upper surface of the platform base for center positioning and clamping of the workpiece.

[0007] A lateral clamping mechanism is symmetrically arranged on the platform base and located around the central positioning component;

[0008] Each of the lateral clamping mechanisms includes: a corner bracket rotatably mounted on the platform base; a lateral support plate fixedly connected to the corner bracket; a clamping drive unit mounted on the lateral support plate; a clamping arm, the middle of which is hinged to the lateral support plate via an adapter, and one end of which is connected to the output end of the clamping drive unit; and a clamping head disposed at the other end of the clamping arm for applying clamping force to the workpiece under the drive of the clamping drive unit.

[0009] As a preferred embodiment of this application, the corner bracket is rotatably mounted on the platform base via a pivot, allowing the lateral clamping mechanism to adjust its angle in the horizontal plane around the pivot. This structure enables the entire lateral clamping mechanism to rotate 360 ​​degrees in the horizontal plane around the axis of the pivot, thereby allowing the pressure head to approach and clamp the workpiece from any horizontal direction, greatly enhancing its adaptability to irregular contours.

[0010] As a preferred technical solution of this application, the corner bracket is a right-angled structure, with multiple positioning holes for fixing on both its horizontal and vertical sides; the horizontal side is connected to the platform base through the pivot and positioning pin, and the vertical side is connected to the side support plate through fasteners.

[0011] The corner bracket has multiple regularly spaced positioning holes on both its horizontal and vertical sides for fasteners. The horizontal side is centered on a pivot shaft and secured to the platform base using positioning pins inserted into different holes. The vertical side is connected to the lateral support plate via bolts or other fasteners. This multi-hole design provides a discrete and robust positioning method.

[0012] As a preferred technical solution of this application, the lateral support plate is connected to the vertical edge of the corner bracket by fasteners, thereby realizing the position adjustment of the lateral support plate in the vertical direction.

[0013] As a preferred embodiment of this application, the pressure head has a multi-tooth structure to form multiple independent clamping points. This allows a single pressure head to simultaneously form multiple independent, discrete clamping points on the working surface. Its advantages include the ability to disperse clamping force, reducing the risk of localized workpiece deformation; simultaneously, multi-point contact better suppresses the workpiece's rotational tendency within the clamping plane, enhancing positioning stability.

[0014] As a preferred embodiment of this application, a replaceable soft pad is provided on the pressing surface of the pressure head. The soft pad prevents the hard metal pressure head from scratching or indenting the workpiece surface, protecting the product's appearance quality; at the same time, it can also compensate for the unevenness of the workpiece surface through the slight deformation of the material itself, increasing friction and making the pressing more reliable.

[0015] As a preferred technical solution of this application, the connection between the pressure arm and the output end of the pressing drive is hinged, and the middle part of the pressure arm and the pressure head form a hinge point.

[0016] As a preferred technical solution of this application, the central positioning component includes:

[0017] A bottom support base, which is fixed to the platform base;

[0018] A lateral adjustment mechanism, which is mounted on the bottom support, is used to adjust the clamping position in the horizontal direction;

[0019] The clamping module, which is mounted on the lateral adjustment mechanism, is used to clamp and position the workpiece.

[0020] As a preferred technical solution of this application, the bottom support includes a main support pad, and a first side plate and a second side plate located on both sides thereon; the lateral adjustment mechanism is a sliding plate disposed in the groove of the second side plate, and the clamping module is installed on the sliding plate by fasteners.

[0021] As a preferred technical solution of this application, the clamping module includes a clamping seat, an arc-shaped bracket disposed on the clamping seat, and a plurality of adjustable positioning seats disposed around the arc-shaped bracket.

[0022] Compared with the prior art, the beneficial effects of this application are as follows: This application achieves omnidirectional position adjustment in three-dimensional space by using the matrix-type threaded holes on the platform base, combined with the lateral adjustment mechanism of the center positioning component and the multi-angle rotation function of the lateral clamping mechanism. Specifically, the combination of the horizontal rotation adjustment of the corner bracket and the vertical height adjustment of the lateral support plate allows the pressure head to be precisely aligned with the workpiece clamping point from any spatial angle, effectively solving the clamping problem of traditional fixtures.

[0023] The center positioning component employs a lateral adjustment mechanism that combines precision guide grooves and sliding plates, along with a multi-point, multi-directional adjustable positioning seat, to achieve precise adjustment of the workpiece's reference positioning. The lateral clamping mechanism utilizes a lever-type pressure arm, effectively converting the cylinder's thrust into a stable, vertically downward clamping force. Combined with the multi-tooth structure design of the pressure head, it not only disperses localized pressure but also enhances anti-rotation capability through multi-point constraints, ensuring the absolute stability of the workpiece during processing.

[0029] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments in this application (for ease of description and understanding, hereinafter referred to as...), Figure 2 (The above is described above). All other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application.

[0030] Please see Figure 1-4 This application provides a technical solution: a multi-directional adjustable fixture debugging platform, including a rigid platform base 2, a central positioning component, and multiple sets of lateral clamping mechanisms. These components work together to form a highly flexible and high-precision workpiece clamping system.

[0031] The platform base 2 exhibits high dimensional stability and rigidity. Its upper surface is precision-machined with a matrix of threaded holes, providing standardized and modular mounting interfaces for the center positioning assembly and lateral clamping mechanism. It can be flexibly installed at any desired position on the base surface according to the workpiece's contour dimensions and securely locked with high-strength hexagonal bolts or T-bolts, ensuring the fundamental rigidity of the entire system.

[0032] The center positioning component is typically located on the upper surface of the platform base 2 in the main area for mounting the workpiece, such as both ends of a long strip workpiece. This component employs a modular design, primarily consisting of three parts: a bottom support base 8, a lateral adjustment mechanism, and a clamping module. The bottom support base 8 is bolted to a predetermined position on the platform base 2. Its main body is the main support pad 13, which directly supports the lower surface of the workpiece, providing stable support. The main support pad 13 has a first side plate 14 and a second side plate 12 on both sides, forming a rigid frame structure. Precision guide grooves are machined on the second side plate 12. A precisely fitted sliding plate 15 is embedded in these grooves, forming the lateral adjustment mechanism. Loosening the locking bolts allows the sliding plate 15 to move smoothly along the grooves, thereby driving the entire clamping module on it to perform coarse adjustment or precise positioning along the approximate length direction (X-axis or Y-axis) of the workpiece. After adjustment, tightening the locking bolts firmly presses the sliding plate 15 onto the second side plate 12, fixing its position. The clamping module is bolted onto the slide plate 15 and directly contacts the workpiece. The clamping module includes a clamping seat, an arc-shaped bracket 1 fixed to the clamping seat, and multiple adjustable positioning seats threaded onto the arc-shaped bracket 1. The operator can screw in or out each adjustable positioning seat according to the workpiece's internal geometry, causing their ends to press against the workpiece's inner wall or a specific reference surface with appropriate force, thereby achieving precise positioning of the workpiece in the central area and flexible clamping at multiple points and in multiple directions.

[0033] Lateral clamping mechanisms provide auxiliary, stable clamping force from the circumference of the workpiece to balance the lateral forces or torques generated during processing and prevent workpiece movement or vibration. They are arranged symmetrically or selectively around the central positioning assembly according to the workpiece's contour.

[0034] Each lateral clamping mechanism is an independent unit. It mainly includes a corner bracket 9, whose horizontal edge is connected to the platform base 2 via a vertically mounted pivot 3, allowing the entire corner bracket 9 to rotate steplessly or in steps around the center line of the pivot 3 in the horizontal plane. Positioning holes are formed around the pivot 3 on the horizontal edge of the corner bracket 9. After adjusting to the desired angle, inserting a positioning pin into the corresponding hole rigidly locks the corner bracket 9 to the platform base 2, preventing rotation during operation.

[0035] Positioning holes are provided vertically along the vertical edge of the corner bracket 9. The lateral support plate 5 is connected to these positioning holes by high-strength bolts. By selecting the hole positions at different heights on the vertical edge, the lateral support plate 5 and all its components can be raised and lowered as a whole, thereby adapting to the clamping requirements of workpieces at different heights.

[0036] A clamping drive 6 is installed on the side or back of the lateral support plate 5. In this embodiment, a single-acting cylinder is preferred because of its fast action speed and convenient control. It can also be replaced with a hydraulic cylinder or an electric push rod according to actual needs. The middle part of the pressure arm 10, which acts as a lever, is hinged to the top of the lateral support plate 5 through the adapter 4. This point is the fulcrum of the lever. One end of the pressure arm 10 is hinged to the piston rod end of the cylinder 6 through a pin, forming the power input end. The other end of the pressure arm 10 is equipped with the final actuating element—the pressure head 11. The pressure head 11 is preferably a multi-tooth structure in the shape of a "mountain". Its advantage is that it can distribute the concentrated clamping force to multiple contact points, which reduces the unit pressure on the workpiece and enhances the anti-rotation capability through multi-point constraint. In order to protect the surface of the workpiece, a replaceable soft pad is usually embedded on the clamping surface of the pressure head 11.

[0037] In use: Plan the initial installation positions of the center positioning component and each lateral clamping mechanism on the platform base 2, and fix them initially in the approximate position of the base with bolts.

[0038] Next, the workpiece is hoisted or placed on the main support pad 13 of the center positioning assembly. Then, the center positioning assembly is finely adjusted: first, the locking bolts of the slide plate 15 are loosened, and the entire clamping module is moved so that the arc-shaped bracket 1 is roughly aligned with the corresponding structure of the workpiece; then, each adjustable positioning seat is finely adjusted so that their ends make stable and reliable contact with and pre-tighten the inner wall of the workpiece, thus completing the precise positioning and main clamping of the workpiece in the center area.

[0039] Next, the lateral clamping mechanism on the perimeter is configured: For each clamping point, the locating pin of the corner bracket 9 is first loosened, and the entire mechanism is rotated horizontally so that the movement trajectory of the pressure head 11 is aligned with the surface of the workpiece to be clamped, without interfering with any protrusions on the workpiece. After adjustment, the locating pin is inserted and locked. Then, as needed, the installation height of the lateral support plate 5 on the vertical side of the corner bracket 9 is adjusted so that the pressure head 11 accurately lands on the ideal clamping area of ​​the workpiece during descent.
