[0002] Fuel injectors are the core components of an internal combustion engine's fuel system. Through precise design, they atomize fuel into tiny particles and inject them accurately, directly affecting combustion efficiency, power output, and exhaust emissions. Internally, they contain structures such as needle valves, nozzle seats, and filters. They must withstand high pressure, high temperature, and high-speed fuel erosion and are usually made of wear-resistant and corrosion-resistant alloy steel or ceramic materials. During the production process, fixtures are usually required to fix them in place to ensure that the fuel injectors remain stable during processing and to avoid dimensional deviations caused by displacement.

[0003] When processing existing fuel injectors, they usually need to be fixed with a fixture. However, most existing fixtures can only fix fuel injectors of a single size, and the fixtures need to be locked manually, which is time-consuming and labor-intensive, affecting the overall processing efficiency.

This solves the problem that existing fuel injectors usually require a fixture for fixing during processing, and most existing fixtures can only fix fuel injectors of a single size. Moreover, manual locking of the fixture is required, which is time-consuming and labor-intensive, affecting the overall processing efficiency.

[0016] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0017] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0018] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0019] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0020] Example 1 Reference Figure 1-4 This is the first embodiment of the present invention, which provides a fixing fixture for producing fuel injectors, including a base 1 and a support frame 2. The support frame 2 is fixedly connected to the top of the base 1. Rectangular through holes 3 are provided on the left and right sides of the top of the inner cavity of the support frame 2. A quick clamping mechanism 4 is provided in the inner cavity of the support frame 2. The quick clamping mechanism 4 includes two clamping components 41 and a control component 42. The control component 42 is located in the inner cavity of the support frame 2, and the two clamping components 41 are symmetrically arranged on the left and right sides inside the control component 42, respectively.

[0021] Specifically, by using the base 1, support frame 2, rectangular through hole 3 and quick clamping mechanism 4 in combination, the effect of quickly clamping workpieces of different sizes is achieved.

[0022] Furthermore, the workpiece is placed at a suitable position on the top of the support frame 2, and then the control component 42 is activated to move downward. During the downward movement, the control component 42 will squeeze the clamping component 41. The squeezing force will force the two clamping components 41 to move closer to each other and clamp and fix the workpiece. The clamping component 41, through the design of the V-shaped opening, can be used for workpieces of different diameters.

[0023] Example 2 The second embodiment of this utility model provides a fixing fixture for producing fuel injectors. The clamping assembly 41 includes a movable plate 411 and a V-shaped clamping block 412. The top of the movable plate 411 passes through the rectangular through hole 3 and extends to the outside of the rectangular through hole 3. The side of the V-shaped clamping block 412 near the movable plate 411 is fixedly connected to the movable plate 411. A rubber anti-slip pad 413 is fixedly connected to the clamping jaw of the V-shaped clamping block 412.

[0024] Support columns 414 are provided on the front and rear sides of the inner cavity of the rectangular through hole 3. The left and right sides of the support columns 414 are fixedly connected to the inner wall of the rectangular through hole 3. The movable plate 411 is sleeved on the surface of the support column 414 and is slidably connected to the support column 414 through a linear bearing. Push columns 415 are fixedly connected to the front and rear sides of the bottom of the movable plate 411.

[0025] Specifically, by setting the push column 415, the control component 42 can squeeze the push column 415, forcing the push column 415 moving plate 411 and V-shaped clamp 412 to move closer to the workpiece and clamp and fix the workpiece. By setting the moving plate 411 and V-shaped clamp 412, the workpiece can be clamped and fixed. The V-shaped opening design of the V-shaped clamp 412 can adapt to workpieces of different diameters. By setting the rubber anti-slip pad 413, the friction between the V-shaped clamp 412 and the workpiece can be increased, preventing the workpiece from rotating and preventing the V-shaped clamp 412 from damaging the surface of the workpiece. By setting the support column 414, the moving plate 411 can be supported and limited, allowing the moving plate 411 to move horizontally in a straight line.

[0026] Furthermore, the control component 42 drives the two push columns 415 to move, and the two push columns 415 drive the fixedly connected moving plates 411 to move synchronously on the surface of the support column 414, so that the two moving plates 411 move closer to each other, thereby driving the V-shaped clamping block 412 to move closer to the workpiece. When the V-shaped clamping block 412 reaches the appropriate position, the rubber anti-slip pad 413 on the inner wall of its V-shaped opening contacts the workpiece and clamps the workpiece. Then the control component 42 stops, the V-shaped clamping block 412 no longer moves, and the workpiece is in a clamped state.

[0027] Example 3 The second embodiment of this utility model provides a fixing fixture for producing fuel injectors. The control component 42 includes a control frame 421. Extrusion holes 422 are provided on both the front and rear sides of the inner wall of the control frame 421. The side of the push column 415 away from the moving plate 411 passes through the extrusion hole 422 and extends into the inner cavity of the extrusion hole 422 to contact the inner wall of the extrusion hole 422. An electric cylinder 423 is provided in the middle of the inner cavity of the control frame 421. The bottom of the electric cylinder 423 is fixedly connected to the base 1, and the output shaft of the electric cylinder 423 is fixedly connected to the control frame 421.

[0028] The extrusion holes 422 on both sides of the inner wall of the front and rear sides of the control frame 421 are evenly and symmetrically arranged. The front and rear sides of the control frame 421 near the inner wall of the support frame 2 are fixedly connected to sliders 424.

[0029] The support frame 2 has grooves 5 on both the left and right sides of its inner wall. The slider 424 passes through the groove 5 on the side away from the control frame 421 and extends into the inner cavity of the groove 5 to contact the inner wall of the groove 5.

[0030] Specifically, by setting up a control frame 421 and two symmetrical extrusion holes 422, the extrusion holes 422 on the surface of the control frame 421 can be used to extrude and push the column 415 during the downward movement of the control frame 421, forcing the two push columns 415 to move. By setting up an electric cylinder 423, the control frame 421 can be automatically driven to rise and fall, thereby enabling the clamping assembly 41 to automatically clamp and release the workpiece, making it convenient for the operator to clamp the workpiece. By setting up a slider 424 and a slide groove 5, the control frame 421 can be limited during the rising and falling process, making it convenient for the control frame 421 to rise and fall vertically.

[0031] Furthermore, the operator activates the electric cylinder 423 to retract, causing the control frame 421, which is fixedly connected to its output shaft, to move down synchronously. During the downward movement of the control frame 421, the inclined surface of the symmetrically opened extrusion holes 422 on its surface extrudes and pushes the column 415. The resulting extrusion force forces the two push columns 415 to move synchronously, thereby driving the moving plate 411 and the V-shaped clamping block 412 to move synchronously, automatically clamping the workpiece. During the downward movement of the control frame 421, the slider 424 moves synchronously with the control frame 421 in the inner cavity of the slide groove 5, limiting the position of the control frame 421.

[0032] Working principle: The workpiece is placed at a suitable position on top of the support frame 2. Then, the operator starts the electric cylinder 423 to retract, which drives the control frame 421, which is fixedly connected to its output shaft, to move down synchronously. During the downward movement, the control frame 421 squeezes the push column 415 through the inclined surface of the symmetrically opened extrusion holes 422 on its surface. The extrusion force generated at this time will force the two push columns 415 to move synchronously. The two push columns 415 drive the moving plate 411, which is fixedly connected to them, to move synchronously on the surface of the support column 414, so that the two moving plates 411 move closer to each other, thereby driving the V-shaped clamp 412 to move closer to the workpiece. When the V-shaped clamp 412 reaches the appropriate position, the rubber anti-slip pad 413 on the inner wall of its V-shaped opening contacts the workpiece and clamps the workpiece. Then, the output shaft of the electric cylinder 423 stops retracting, and the V-shaped clamp 412 stops moving. At this time, the workpiece is in a clamped state, and the work is completed.

[0033] In summary, by using the base 1, support frame 2, rectangular through hole 3, and quick clamping mechanism 4 in combination, the problem of needing a fixture to fix the existing fuel injector during processing is solved. However, most existing fixtures can only fix fuel injectors of a single size, and manual locking of the fixture is required, which is time-consuming and labor-intensive and affects the overall processing efficiency. This achieves the effect of quickly clamping workpieces of different sizes.
