Description

Technical Field

[0001] The utility model relates to the field of shrapnel detection, in particular to an adjustable fixture for shrapnel detection. Background Technique

[0002] A shrapnel is a common metal fitting, generally a metal sheet, with a certain elastic deformation ability. After the shrapnel is produced, it usually needs to be detected. In the prior art, an OMM image measuring instrument is generally used for detection. In order to prevent the shrapnel from moving randomly, a fixture is needed to fix it. In the prior art, a groove with an unadjustable shape is generally used to fix the shrapnel. In this way, during fixation, it cannot be adjusted according to the different thicknesses of the shrapnel, and the applicability is poor.

[0003] After retrieval, Chinese Patent Publication No.: CN219170639U discloses a rapid detection tooling fixture for metal shrapnel, including a base and a cover plate. An insert groove is provided at the center of the base, and first limit holes are respectively arranged at both ends of the insert groove. A limit stud is arranged in each first limit hole; insert holes are provided on the cover plate, and second limit holes corresponding to the first limit holes one by one are respectively arranged at both ends of the insert holes, and limit pins are installed in the second limit holes. The structure of the utility model is simple. An insert is arranged in the insert groove of the base. The insert passes through the insert hole of the cover plate and is located in the insert hole. The metal shrapnel to be detected is placed in the insert hole to form a limit constraint on the metal shrapnel. After the measurement is completed, the cover plate is pressed. The spring arranged between the cover plate and the base is a tension spring. Under the action of the spring force, the cover plate ejects the metal shrapnel, completing rapid unloading and improving the detection efficiency.

[0004] When this device is in use, since the cover plate itself cannot be adjusted, when it is necessary to fix shrapnels with different thicknesses, it is necessary to replace the cover plate again to match shrapnels with different thicknesses. The overall device has poor applicability during use. For this reason, an adjustable fixture for shrapnel detection is proposed to solve the above problems. Content of the Utility Model

[0029] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0030] Refer to Figure 1 - Figure 3, an embodiment provided by the present utility model: a shrapnel detection adjustable fixture, including a base 1 for supporting the overall device. A slide bar 2 for guiding the sliding of a slide plate 4 is fixedly connected to the top end of the base 1. A closing cap 3 for closing the top pipe opening of the slide bar 2 is threadedly connected to the top end of the slide bar 2. A slide plate 4 is slidably connected to the outer wall of the slide bar 2. Due to the limitation of the slide bar 2, the slide plate 4 can only slide vertically up and down. A fixing groove 5 for accommodating the shrapnel is provided at the top end of the slide plate 4. A stopper 6 for blocking the slide plate 4 is inserted into the front end of the base 1. The stopper 6 can also support the shrapnel. A rubber block 7 for fixing the stopper 6 is fixedly connected to the front end of the base 1. The rubber block 7 has the ability of elastic deformation and will undergo elastic deformation when being squeezed. By pulling the stopper 6, it can be separated from the base 1, and then the stopper 6 can be replaced. A clamping assembly 8 for fixing the shrapnel is provided at the top end of the slide plate 4. The clamping assembly 8 includes a slider 81 for driving the movement of an adjusting plate 84. The slider 81 is slidably connected to the inner wall of the slide plate 4.

[0031] Refer to Figure 1 - Figure 3 , the clamping assembly 8 further includes an adjusting plate 84 for driving the movement of a pressing block 82. The adjusting plate 84 penetrates and is slidably connected to the rear end of the slider 81. The adjusting plate 84 is integrally arranged in an L shape, so that it is convenient for the operator to move it back and forth. A pressing block 82 for pressing the shrapnel is fixedly connected to the front end of the adjusting plate 84. A rubber pad 83 for directly contacting the shrapnel is fixedly connected to the front end of the pressing block 82. A compression spring 85 for pushing the slider 81 is fixedly connected to the front end of the slider 81. The front end of the compression spring 85 is fixedly connected to the inner wall of the slide plate 4. The compression spring 85 will always push the slider 81 forward. A pressing plate 88 for pressing the adjusting plate 84 is slidably connected to the inner wall of the slider 81. The pressing plate 88 is made of rubber and has a relatively rough surface, which can provide a large frictional force when contacting the adjusting plate 84. A threaded rod 811 for driving the movement of the pressing plate 88 is rotatably connected to the top end of the pressing plate 88. A threaded sleeve 89 for pressing the threaded rod 811 is fixedly connected to the top end of the slider 81. The threaded rod 811 and the threaded sleeve 89 are in threaded connection. By rotating the threaded rod 811, its up and down movement can be driven, and at the same time, the threaded rod 811 will drive the pressing plate 88 to move up and down. A knob 810 for facilitating the operator to rotate the threaded rod 811 is fixedly connected to the top end of the threaded rod 811.

[0032] Refer to Figure 1 - Figure 3, a cylindrical block 86 for driving the slider 81 to move is fixedly connected to the right end of the slider 81. The cylindrical block 86 penetrates and is slidably connected to the right end of the slide plate 4. When the cylindrical block 86 moves, the slider 81 will move synchronously. An inclined plate 87 for pressing the cylindrical block 86 is fixedly connected to the top end of the base 1. The cylindrical block 86 slides on the top end of the inclined plate 87. Multiple groups of the cylindrical block 86 and the inclined plate 87 are provided, and multiple groups of the cylindrical block 86 and the inclined plate 87 are symmetrically arranged with the center line of the slider 81 as the axis of symmetry. Two groups of the cylindrical block 86 will drive the two ends of the slider 81 to move smoothly.

[0033] Working principle: When detection is required, the slide plate 4 can be pressed to drive the slider 81 to move downward. The downward movement of the slider 81 will drive the cylindrical block 86 to press the inclined plate 87. The cylindrical block 86 will move backward along the inclined surface at the top end of the inclined plate 87. The backward movement of the cylindrical block 86 will drive the slider 81 to move backward synchronously. The slider 81 will drive the extrusion block 82 to move backward synchronously. At this time, the fixing groove 5 will be exposed. Then, the elastic piece can be inserted into the inside of the fixing groove 5, and one end of the elastic piece is supported by the stopper 6. Then, the slide plate 4 can be released. The compression spring 85 will push the slider 81 to move forward and reset. At the same time, the slider 81 will drive the cylindrical block 86 to press the inclined surface of the inclined plate 87 to drive the slider 81 to move upward again. The slider 81 will drive the slide plate 4 to move upward and reset. At the same time, the slider 81 will drive the extrusion block 82 and the rubber pad 83 to press the elastic piece so that the elastic piece is fixed inside the fixing groove 5. Since the elastic piece itself is light in weight, too much pressing force is not required.

[0034] When elastic pieces of different sizes need to be adapted, the adjusting plate 84 can be toggled to move it back and forth. The adjusting plate 84 will drive the extrusion block 82 to move, so as to change the distance between the extrusion block 82 and the slider 81. After the spacing is adjusted, the knob 810 can be rotated to drive the threaded rod 811 to rotate. The threaded rod 811 drives the extrusion plate 88 to move up and down. By using the extrusion plate 88 to press the adjusting plate 84, it can be fixed. In this way, by adjusting the distance between the extrusion block 82 and the slider 81, the clamping range of the overall device can be adjusted without changing the movement track of the slider 81, so as to clamp elastic pieces of different sizes.

[0035] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
