Description

Technical Field

[0001] This utility model relates to the field of flattening fixture technology, and in particular to a novel flattening fixture for improving flatness. Background Technology

[0002] For two parts that are snapped together, such as the housing and fuse of a surface mount fuse, a flattening process is required after the snap-fit ​​assembly is completed to ensure the flatness and consistency of the product. This is done by using a flattening device to further press the product together.

[0003] A Chinese utility model patent with patent number ZL 202223594201.8 and patent name entitled "Thermal Printing Module Flattening Fixture" discloses the following technical solution: The thermal printing module flattening fixture includes a base, a cover plate, and several elastic rods. The base and the cover plate are used to place the thermal printing module. The elastic rod includes a pull rod, an elastic element, and a sliding sleeve. The lower end of the pull rod is hinged to the base, and the upper end is equipped with an abutment block. The elastic element and the sliding sleeve are respectively sleeved on the pull rod. The elastic element is located between the abutment block and the sliding sleeve. After the pull rod is rotated to a vertical position, the sliding sleeve presses the cover plate tightly under the action of the elastic element. A guide mechanism for guiding the lifting and lowering of the cover plate is installed between the base and the cover plate. The guide mechanism includes several guide rods. The guide rods are fixed on the base, and the cover plate can be lifted and slidably mounted on the guide rods.

[0004] When using the aforementioned thermal printing module flattening fixture, place the thermal printing module on the base, then cover it with the cover plate. Rotate each elastic rod to a vertical position, so that the sliding sleeves of each elastic rod press the cover plate under the action of the elastic element, thereby completing the flattening operation of the thermal printing module. After the thermal printing module is flattened, rotate each elastic rod to release the pressing action of the sliding sleeves on the cover plate, then remove the cover plate upward along the guide rod, and finally remove the flattened thermal printing module from the base.

[0005] It should be noted that the aforementioned thermal printing module flattening fixture has the following drawbacks, specifically: Defect 1: When performing the flattening operation, each elastic rod needs to be rotated to a vertical position. After the flattening operation is completed, each elastic rod needs to be rotated and the sliding sleeve needs to be released from pressing the cover plate. The whole operation process is complicated and inconvenient. Defect 2: The cover plate cannot be lifted automatically. Before removing the flattened thermal printing module, the operator needs to manually push the cover plate upward along the guide rod, which is inconvenient to operate. Utility Model Content

Detailed Implementation

[0019] The present invention will now be described in conjunction with specific embodiments.

[0020] Example 1, as Figures 1 to 3 As shown, a novel flatness flattening fixture includes a base plate 1 and a cover plate 2 that is movably mounted on top of the base plate 1. The base plate 1 is equipped with a number of guide posts 3 that are spaced apart and extend vertically upwards. The cover plate 2 has a vertically penetrating guide hole 21 corresponding to each guide post 3. The upper end of each guide post 3 is inserted into the corresponding guide hole 21.

[0021] Among them, such as Figures 1 to 3 As shown, each guide post 3 is fitted with a return spring 4 on its periphery. The upper end of each return spring 4 abuts against the cover plate 2, and the lower end of each return spring 4 abuts against the base plate 1.

[0022] Furthermore, such as Figures 1 to 3As shown, the base plate 1 is equipped with several spaced-apart adjustment brackets 5 located on the periphery of the cover plate 2. The upper end of each adjustment bracket 5 is provided with a bolt mounting part 51 located above the cover plate 2. Each bolt mounting part 51 is provided with a vertically penetrating internal threaded hole 511. Each bolt mounting part 51 has a vertically arranged adjustment bolt 6 screwed into the internal threaded hole 511. The lower end face of each adjustment bolt 6 abuts against the upper surface of the cover plate 2.

[0023] Furthermore, the new flatness flattening fixture is equipped with a workpiece carrier plate 7, and the upper surface of the workpiece carrier plate 7 is provided with a plurality of workpiece placement holes 71 arranged in an array; the upper surface of the base plate 1 is provided with a forward-opening alignment groove 11 for aligning and placing the workpiece carrier plate 7.

[0024] The following describes the novel flatness flattening fixture of Embodiment 1 in conjunction with the specific action process. The steps of its working process include: Step 1: Place the workpieces to be flattened into the workpiece placement holes 71 of the workpiece carrier plate 7 in sequence. The workpiece placement holes 71 adopt a contour design, and the outline shape of each workpiece placement hole 71 is consistent with the outline shape of the workpiece, that is, the workpiece placement holes 71 can accurately position the workpiece. Step 2: Insert the workpiece carrier plate 7 containing the workpiece through the front opening of the alignment groove 11, and push the workpiece carrier plate 7 backward into place to achieve the placement and positioning of the workpiece carrier plate 7 and the workpiece to be flattened. Step 3: After the workpiece carrier plate 7 loaded with workpieces is placed in place, tighten each adjusting bolt 6. At this time, each adjusting bolt 6 moves downward relative to the bolt mounting part 51 of the adjusting bracket 5, and each adjusting bolt 6 pushes the cover plate 2 downward. During this process, the cover plate 2 moves downward after being guided by the guide post 3 until the cover plate 2 presses against each workpiece on the workpiece carrier plate 7. Step 4: After flattening the workpiece on the workpiece carrier plate 7, loosen all adjusting bolts 6. During this process, the spring force of the return spring 4 pushes the cover plate 2 upward. After the cover plate 2 moves to a certain height, the worker can pull the workpiece carrier plate 7 loaded with the flattened workpiece out of the alignment groove 11 of the base plate 1. Step 5: After the workpiece carrier plate 7 loaded with the flattened workpiece is pulled out from the alignment groove 11 of the base plate 1, the workpiece carrier plate 7 loaded with the unflattened workpiece is pushed into the alignment groove 11 of the base plate 1, and the subsequent workpiece flattening process is completed according to steps 2-4 above.

[0025] It should be emphasized that when the adjusting bolt 6 is loosened, the cover plate 2 automatically moves upward and moves away from the workpiece under the elastic force of the return spring 4. Compared with the prior art, the new flatness flattening fixture in this embodiment does not require manual operation to lift the cover plate 2 when unloading, making it convenient to operate and use.

[0026] Furthermore, during the entire flattening operation, from the time the workpiece carrier plate 7 is placed in until it is removed, the operator only needs to rotate the operating adjustment bolt 6, without having to rotate the elastic rod in the prior art, making the operation convenient.

[0027] In addition, by opening the alignment groove 11 structure on the upper surface of the base plate 1, this embodiment can realize the quick and accurate positioning of the workpiece carrier plate 7 in the flattening operation position, thereby further improving the convenience of operation and use.

[0028] In summary, the novel flatness flattening fixture of this embodiment has the advantages of novel structural design and convenient operation through the above structural design.

[0029] Example 2, as Figure 2 and Figure 3 As shown, the difference between this embodiment 2 and embodiment 1 is that: the lower surface of the cover plate 2 is provided with a soft rubber pad 8 arranged horizontally, and the lower surface of the soft rubber pad 8 is provided with a downward protruding boss 81 corresponding to the workpiece placement hole 71 of the workpiece carrier plate 7.

[0030] In this embodiment, the soft rubber pad 8 is screwed and fastened to the lower surface of the cover plate 2. Of course, the above screwing fastening method does not constitute a limitation on this embodiment, that is, the soft rubber pad 8 in this embodiment can also be installed on the lower surface of the cover plate 2 by a snap-fit ​​method.

[0031] It should be explained that the soft rubber pad 8 has the ability to stretch and expand elastically. When the cover plate 2 moves down and flattens the workpiece, the cover plate 2 presses against the workpiece through the protrusion 81 of the soft rubber pad 8. This can achieve elastic pressing of the workpiece and effectively prevent the workpiece from being scratched when flattened.

[0032] Example 3, as Figures 1 to 3 As shown, the difference between this embodiment 3 and embodiment 1 is that the adjusting bracket 5 further includes a vertically arranged bracket vertical part 52, and a bracket fixing part 53 is provided at the lower end of the bracket vertical part 52. The bracket fixing part 53 is screwed and fastened to the base plate 1, and the bolt mounting part 51 is provided at the upper end of the bracket fixing part 53.

[0033] Example 4, as Figures 1 to 3 As shown, the difference between this embodiment four and embodiment one is that the inherent pad 9 is screwed onto the lower surface of the base plate 1.

[0034] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
