Description

Technical Field

[0001] This utility model relates to the field of tooling and fixture technology, and in particular to a riveting and welding fixture for a deflector workpiece. Background Technology

[0002] As a key structural component in specific equipment, the manufacturing precision of the deflection seat directly affects the performance and stability of the entire device. During the production of the deflection seat, it typically requires the assembly of multiple plates, supports, and other parts into a single unit through riveting and welding. To ensure the dimensional accuracy and geometric tolerances of the final product, specialized riveting and welding fixtures must be used to precisely position and securely clamp each part, providing a stable reference for subsequent riveting and welding operations.

[0003] In existing riveting and welding production of deflector seats or similar complex workpieces, mechanical clamping fixtures are widely used. These fixtures typically have multiple positioning blocks and reference surfaces on the base. After the operator places the various parts of the workpiece into the designated positions on the fixture, they then use mechanical methods such as manually rotating bolts, moving pressure plates, and engaging toggle clamps to clamp and secure multiple key parts of the workpiece point by point. This traditional mechanical fixture can meet basic production needs to a certain extent and is currently a common method for ensuring welding quality and efficiency.

[0004] However, the aforementioned traditional mechanical riveting and welding fixtures have the following obvious technical problems in practical use: Due to the complex structure of the workpiece and the numerous points requiring fixation, operators need to manually tighten or loosen a large number of bolts, pressure plates, and other mechanical clamping devices one by one. During the workpiece loading and unloading process, this series of repetitive manual operations consumes a significant amount of auxiliary time, limiting the overall production cycle time and efficiency.

[0005] Uneven and difficult-to-control clamping force. The amount of force applied manually depends on the operator's experience and physical condition, making it difficult to ensure that the clamping force at every clamping point on the workpiece is consistent and appropriate. Excessive clamping force may cause stress deformation of the workpiece, affecting welding accuracy; insufficient clamping force may cause the workpiece to shift due to heat during welding, which will also result in scrapped finished products and poor product quality consistency.

[0006] Therefore, how to design a riveting and welding fixture for deflector workpieces that is easy to operate, has reliable clamping, can quickly complete workpiece loading and unloading, and avoids interference with riveting and welding operations is a technical problem that urgently needs to be solved in this field. Utility Model Content

[0007] The technical problem to be solved by this utility model is that the existing riveting and welding fixtures for deflection seat workpieces mainly adopt manual mechanical clamping, which has problems such as cumbersome operation, low clamping efficiency, uneven and difficult-to-control clamping force, and the fixture itself is prone to causing spatial interference to the welding operation. This utility model provides a riveting and welding fixture for deflection seat workpieces that is easy to operate, reliable in clamping, and can significantly improve production efficiency.

[0008] The technical solution adopted by this utility model to solve its technical problem is: A riveting and welding fixture for a deflector workpiece, comprising: The tooling base has multiple pads fixedly installed on its upper surface; At least one clamping assembly, the clamping assembly comprising: The slide rail is fixed on the tooling base; The slider is slidably mounted on the slide rail and moves along the length of the slide rail. The first locking mechanism is provided on the slider and is used to lock the slider at a predetermined position on the slide rail. The fixed shaft is fixedly mounted on the slider. The rotating seat is movably mounted on the fixed shaft and rotates around the central axis of the fixed shaft. The second locking mechanism is installed on the rotating seat and is used to lock the rotation angle of the rotating seat; An electromagnet is mounted on a rotating base; The controller, electrically connected to the electromagnet, is used to control the electromagnet's energization and de-energization.

[0009] Preferably, two sets of clamping assemblies are symmetrically arranged on both sides of the tooling base.

[0010] Preferably, the fixed shaft is a hexagonal shaft, and the rotating seat is provided with a sleeve hole that matches the cross-sectional shape of the hexagonal shaft.

[0011] Preferably, the first locking mechanism is a locking bolt, which passes through the slider and radially abuts against the slide rail.

[0012] Preferably, the second locking mechanism is a locking screw, which passes through the rotating seat and abuts radially against the plane of the hexagonal shaft.

[0013] Preferably, an electromagnet mounting bracket is integrally formed on the rotating base, and the electromagnet is detachably fixed to the electromagnet mounting bracket by mounting screws.

[0014] Preferably, the electromagnet is a rectangular electromagnet.

[0015] The beneficial effects of this utility model are as follows: By setting up a two-stage adjustment system consisting of a slide rail, a slider, a first locking mechanism, a rotating seat, and a second locking mechanism, and combining it with an electromagnetic clamping system formed by an electromagnet and a controller, rapid and precise workpiece positioning and one-button synchronous clamping are achieved. This effectively solves the problems of cumbersome operation and low clamping efficiency, significantly shortens auxiliary time, and improves overall production cycle time and efficiency.

[0016] By controlling all electromagnets in a unified manner through the controller, synchronous energization and de-energization release of all clamping points are achieved, ensuring a constant and uniform distribution of clamping force. This effectively solves the problem of uneven and difficult-to-control clamping force, avoids quality issues such as workpiece stress deformation due to excessive clamping force or workpiece displacement due to insufficient clamping force, and improves the consistency of product quality.

[0017] By adjusting the position of the slider on the slide rail and the angle of the rotating seat around the fixed axis, a dual adjustable clamping system is formed, which realizes flexible adaptation to workpieces with different widths and surface tilt angles. This solves the problems of poor tooling adaptability and insufficient versatility. In particular, it can effectively clamp inclined surfaces, greatly enhancing the versatility and application range of the tooling. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments, but these specific embodiments do not limit the scope of protection of the present invention in any way. Example

[0021] like Figure 1-2 As shown, this utility model discloses a riveting and welding fixture for deflector seat workpieces, which is used to accurately position and reliably clamp deflector seat workpieces before riveting and welding them.

[0022] Specifically, the riveting fixture for the deflector workpiece includes a fixture base 1, a plurality of pads 2 disposed on the fixture base 1, and at least one clamping assembly. In this embodiment, preferably, two sets of clamping assemblies are symmetrically arranged on both sides of the fixture base 1 to form a stable and symmetrical clamping force on the workpiece.

[0023] The fixture base 1 serves as the fundamental load-bearing platform for the entire fixture. It is preferably constructed from welded steel frames to ensure overall stability and rigidity, effectively bearing the weight of the workpiece and the stresses generated during processing. On the upper surface of the fixture base 1, multiple pads 2 are welded to the bottom contour of the deflection seat workpiece to be processed. Their function is to provide a preliminary positioning reference and a stable support surface for the workpiece when it is placed, ensuring that the workpiece is in a correct basic position before clamping.

[0024] The key feature of this invention lies in the innovative structure of the clamping assembly. Specifically, the clamping assembly includes: a slide rail 3 fixed on the tooling base 1, and a slider 4 slidably mounted on the slide rail 3. The slider 4 can move along the length of the slide rail 3 to adjust the position of the entire clamping assembly on the tooling base 1, thereby accommodating workpieces of different widths.

[0025] To achieve position fixation, the slider 4 is provided with a first locking mechanism. In one specific embodiment, the first locking mechanism is a locking bolt 5, which passes through the slider 4 and can radially abut against the slide rail 3. When the operator moves the slider 4 to the predetermined position, by tightening the locking bolt 5, the slider 4 can be firmly locked in the current position of the slide rail 3 by using friction.

[0026] Furthermore, a fixed shaft 6 is fixedly mounted on the slider 4. Preferably, the fixed shaft 6 is a hexagonal shaft, which serves as the mounting reference for the subsequent clamping unit. In this embodiment, the hexagonal shaft itself does not rotate, but moves synchronously with the slider 4.

[0027] At least one rotating seat 7 is movably mounted on the hexagonal shaft. The rotating seat 7 has a sleeve hole that matches the cross-sectional shape of the hexagonal shaft, allowing it to fit onto the shaft and rotate about its central axis. To lock the rotation angle of the rotating seat 7, a second locking mechanism is provided. More specifically, this second locking mechanism is a locking screw 8 that passes through the wall of the rotating seat 7 and radially abuts against a plane of the hexagonal shaft. Utilizing the characteristic of the hexagonal shaft having six planes, this point-to-surface locking method is very stable and reliable, effectively preventing accidental rotation of the rotating seat 7 when clamping a workpiece.

[0028] Preferably, the rotating base 7 has an integrally formed electromagnet mounting bracket 9, and a rectangular electromagnet 10 is detachably fixed to the bracket by mounting screws. All rectangular electromagnets 10 are electrically connected to an external controller 11 via wires. The controller 11 can realize one-button synchronous energization and clamping or de-energization and release of all electromagnets.

[0029] The working process and usage method of this utility model are as follows: The operator loosens the first locking mechanism on slider 4, and then manually moves slider 4 along slide rail 3 until the distance between the two clamping assemblies matches the width of the workpiece to be processed. After adjustment, the first locking mechanism is tightened to fix slider 4 in its current position.

[0030] Loosen the second locking mechanism on the rotating seat 7 and rotate the rotating seat 7 by hand until the angle of the adsorption surface of the rectangular electromagnet 10 mounted on it is fully aligned with the surface of the workpiece to be clamped. After adjustment, tighten the second locking mechanism to fix the angle of the rotating seat 7.

[0031] Place the deflector workpiece to be processed on the pad 2 of the fixture base 1. Then, press the "Power On" or "Clamp" button on the controller 11. After pressing, all the rectangular electromagnets 10 will generate magnetic force simultaneously, firmly attracting and fixing the workpiece.

[0032] With the workpiece in a fixed state, the riveting and welding of the workpiece begins. After all the riveting and welding operations are completed, the operator presses the "power off" or "release" button on the controller 11, and the magnetic force of all rectangular electromagnets 10 will immediately disappear. Finally, the finished deflection seat is removed from the fixture.

[0033] This utility model discloses a riveting and welding fixture for deflector workpieces. By upgrading traditional mechanical clamping to electromagnetic clamping and designing a two-stage manual adjustment mechanism, it achieves significant beneficial effects. First, it solves the problems of cumbersome operation and low efficiency. One-button electronically controlled synchronous clamping / release replaces the repetitive labor of manual tightening point by point, greatly shortening auxiliary time. Second, it solves the problems of uneven clamping force and unstable quality. The constant and uniform electromagnetic force ensures the reliability and repeatability of clamping, effectively preventing workpiece displacement during processing due to uneven force or insecure clamping, thus improving product quality consistency. Third, the non-contact magnetic clamping method of the electromagnet avoids the space occupation of traditional mechanical fixtures around the workpiece, effectively releasing the riveting and welding operation area and solving the problem of the fixture itself easily causing spatial interference to the welding operation, providing a larger operating space and better accessibility for riveting and welding operations. Most importantly, the position adjustment of the slider 4 and the angle adjustment of the rotating seat 7 solve the problem of poor adaptability of traditional fixtures. This tooling can flexibly adapt to workpieces of different sizes and shapes, and in particular, it can effectively clamp inclined surfaces, greatly enhancing the versatility of the tooling.

[0034] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any innovative improvements or substitutions based on this utility model should fall within the scope of the claims of this utility model. Furthermore, the parameters, materials, and processes mentioned in the above embodiments are not unique. Without departing from the technical essence of this utility model, those skilled in the art can make various alternatives, and these alternative solutions should also be considered to fall within the scope of protection of this utility model.
