Description

Technical Field

[0001] This utility model relates to the field of front panel processing technology, and in particular to a front panel processing positioning fixture. Background Technology

[0002] Front panel machining positioning fixture is a positioning and clamping tool used in the machining process of front panels (such as automotive front panels, electronic device front panels, etc.). Its main function is to accurately fix the front panel on the machining equipment, ensuring that the front panel can be accurately cut, drilled, welded or other machining operations according to design requirements during the machining process.

[0003] The drawbacks of existing front panel machining and positioning fixtures when clamping front panel workpieces are mainly reflected in the following aspects: Existing fixtures are usually designed with a fixed clamping method, that is, the fixture can only provide one fixed force or fixing method. This single clamping method may not provide effective support and stability for front panel workpieces of different sizes, shapes and materials, resulting in the front panel workpieces not being accurately positioned, or even deformation or damage. For some special front panel workpieces, it may be necessary to apply additional clamping force at specific positions or different parts of the front panel workpiece. However, existing fixtures cannot automatically adjust the clamping position according to the shape or size of the front panel workpiece, and cannot flexibly meet this requirement. Utility Model Content

[0004] To overcome the shortcomings of the existing technology, this utility model provides a front plate processing positioning fixture. Unlike the traditional fixed clamping method, this device is designed with a moving mechanism and an auxiliary clamping mechanism. The clamping position and force can be adjusted according to the size and shape of different front plate workpieces. In particular, the clamping method can be flexibly adjusted through components such as sliders, movable rods, and nuts in the moving mechanism.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a front plate processing and positioning fixture, including a fixture base, the fixture base including a placement plate located at the lowest end of the entire device and two sets of limiting blocks disposed on the placement plate, a front plate workpiece is placed on the placement plate, the two sets of limiting blocks fit and limit the right angle surfaces formed by the two side walls of the front plate workpiece, a positioning system is also provided on the placement plate, a moving mechanism is provided inside the placement plate, an auxiliary clamping mechanism is connected to the moving mechanism, the auxiliary clamping mechanism slides through the moving mechanism, two sets of auxiliary clamping mechanisms are provided, the two sets of auxiliary clamping mechanisms clamp the other two side walls of the front plate workpiece.

[0006] As a preferred embodiment of this utility model, the auxiliary clamping mechanism includes a base plate connected to the moving mechanism, a first hinge shaft disposed on the base plate, a lever hinged at one end to the first hinge shaft, a second hinge shaft disposed on the other end of the lever, a clamping rod hinged to the lever via the second hinge shaft, and a clamping pad fixed to the end of the clamping rod.

[0007] As a preferred embodiment of this utility model, the bottom end of the actuating rod is hinged to the base plate via a first hinge shaft, the middle part of the actuating rod is hinged to the end of the clamping rod via a second hinge shaft, and the upper end of the actuating rod is provided with a handle.

[0008] As a preferred embodiment of this utility model, the clamping rod is slidably connected within the base plate, the outer end of the clamping rod is hinged to the middle of the actuating rod via a second hinge shaft, and a clamping pad is fixed to the inner end of the clamping rod.

[0009] As a preferred technical solution of this utility model, the moving mechanism includes a first slot opened in the placement plate, a second slot opened at the upper end of the first slot, a slider movably connected in the first slot, a movable rod with one end connected to the outer wall of the slider, an external thread opened on the outer end wall of the movable rod, a moving block inserted into the movable rod, and a nut threadedly connected to the external thread.

[0010] As a preferred embodiment of this utility model, the top end of the slider is fixedly connected to the base plate through the second slot, and the width of the first slot is set to be equal to the width of the front plate workpiece.

[0011] Compared with the prior art, the beneficial effects that this utility model can achieve are:

[0012] 1. Unlike traditional fixed clamping methods, this device is designed with a moving mechanism and an auxiliary clamping mechanism, which can adjust the clamping position and force according to the size and shape of different front plate workpieces. In particular, through components such as sliders, movable rods, and nuts in the moving mechanism, the clamping method can be flexibly adjusted. This means that no matter what the size of the front plate workpiece is, the tooling can adjust the clamping range and force according to actual needs, thereby providing more precise support and stability.

[0013] 2. Traditional tooling can only provide one fixed clamping method and cannot adapt to front plate workpieces of different shapes and materials. However, this tooling is designed with two sets of auxiliary clamping mechanisms and positioning system, which can accurately clamp each side wall of the front plate workpiece, ensuring that even front plate workpieces with irregular shapes or special materials can be firmly clamped. The tooling can also flexibly adjust the clamping angle and force to ensure that the front plate workpiece is not deformed or damaged during processing.

[0014] 3. By using two sets of limit blocks and positioning system together, the front plate workpiece can be accurately positioned, ensuring that the clamping position of the front plate workpiece remains stable at all times. This avoids the machining error caused by inaccurate positioning of the front plate workpiece, which is especially important in the machining of precision front plate workpieces or special front plate workpieces, and can effectively improve machining accuracy and quality.

[0021] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this utility model. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0022] Example:

[0023] like Figure 1-5As shown, a front panel processing and positioning fixture includes a fixture base 1. The fixture base 1 includes a placement plate 11 located at the lowest end of the entire device and two sets of limiting blocks 12 disposed on the placement plate 11. A front panel workpiece 2 is placed on the placement plate 11. The two sets of limiting blocks 12 fit and limit the right angle surfaces formed by the two side walls of the front panel workpiece 2. A positioning system 3 is also provided on the placement plate 11. A moving mechanism 5 is provided inside the placement plate 11. An auxiliary clamping mechanism 4 is connected to the moving mechanism 5. The auxiliary clamping mechanism 4 slides through the moving mechanism 5. Two sets of auxiliary clamping mechanisms 4 are provided. The two sets of auxiliary clamping mechanisms 4 clamp the other two side walls of the front panel workpiece 2.

[0024] The auxiliary clamping mechanism 4 includes a base plate 41 connected to the moving mechanism 5, a first hinge shaft 43 disposed on the base plate 41, a lever 42 hinged at one end to the first hinge shaft 43, a second hinge shaft 44 disposed at the other end of the lever 42, a clamping rod 45 hinged to the lever 42 via the second hinge shaft 44, and a clamping pad 46 fixed to the end of the clamping rod 45.

[0025] When it is necessary to clamp the right-angled surfaces formed by the other two side walls of the front plate workpiece 2, simply push the handle of the lever 42 inward so that the bottom end of the lever 42 rotates through the first hinge shaft 43. At the same time, the middle part of the lever 42 pushes the clamping rod 45 to slide forward. During the sliding process, the clamping pad 46 clamps the outer wall of the front plate workpiece 2.

[0026] It is worth noting that the bottom end of the lever 42 is hinged to the base plate 41 via the first hinge shaft 43, and the middle part of the lever 42 is hinged to the end of the clamping rod 45 via the second hinge shaft 44. The upper end of the lever 42 is provided with a handle. This hinge structure can ensure that the lever 42 can rotate during operation without the need for linear thrust, reducing friction and force transmission problems. At the same time, the hinge can ensure that the clamping rod 45 can slide smoothly when the lever 42 is pushed, and can provide sufficient clamping force when needed.

[0027] The clamping rod 45 is slidably connected within the base plate 41. The outer end of the clamping rod 45 is hinged to the middle of the actuating rod 42 via the second hinge shaft 44. The inner end of the clamping rod 45 is fixed with a clamping pad 46, which allows the clamping rod to slide along a predetermined trajectory. During the clamping process, the clamping pad 46 accurately applies clamping force to the front plate workpiece 2. The combination of sliding connection and hinge makes the clamping operation more flexible and stable.

[0028] The moving mechanism 5 includes a first slot 51 opened in the placement plate 11, a second slot 52 opened at the upper end of the first slot 51, a slider 53 movably connected in the first slot 51, a movable rod 54 with one end connected to the outer wall of the slider 53, an external thread 55 opened on the outer end wall of the movable rod 54, a moving block 56 inserted into the movable rod 54, and a nut 57 threadedly connected to the external thread 55.

[0029] When it is necessary to clamp front plate workpieces 2 of different sizes, if the front plate workpiece 2 is long, the nut 57 can be rotated outward so that the nut 57 rotates outward on the external thread 55. The nut 57 first separates from the outer wall of the moving block 56. At this time, the moving block 56 is released from the outer wall of the placement plate 11. Then the base plate 41 can be moved so that the base plate 41 drives the slider 53 to slide in the first slot 51. After the base plate 41 is moved to the position to be clamped, the nut 57 is rotated inward so that the nut 57 returns to its original position. The nut 57 fits against the moving block 56 and pushes the moving block 56 to clamp and limit the outer wall of the placement plate 11. At this time, the auxiliary clamping mechanism 4 can be operated to clamp the side wall of the front plate workpiece 2.

[0030] It is worth noting that the top of the slider 53 passes through the second slot 52 and is fixedly connected to the base plate 41. The width of the first slot 51 is set to be equal to the width of the front plate workpiece 2. The slider 53 slides in the placement plate 11 through the first slot 51. At the same time, the width of the slot matches the width of the front plate workpiece 2. This ensures that the clamping mechanism can accurately position front plate workpieces of different widths, thereby improving the clamping accuracy and stability.

[0031] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

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 preferred examples and are not intended to limit the utility model.
