Description

Technical Field

[0001] The utility model relates to an adjustment baffle of a metallographic cutting machine which does not need to be disassembled. Background Art

[0002] The metallographic cutting machine uses a high-speed rotating thin-sheet grinding wheel to intercept metallographic specimens, and is suitable for cutting various metal materials in metallographic laboratories. To ensure safety, the cutting machine is equipped with an intrinsic safety interlock device, and the cutting button can only be activated when the adjustment cover is completely closed. However, when the cutting length exceeds 20 cm, the adjustment cover cannot be completely closed, so the cutting work cannot be performed. To solve this problem, a removable baffle is designed on the left side of the cutting machine to facilitate the cutting of large-size specimens. The baffle is fixed by 5-7 screws, and the baffle can be removed when the cutting size is greater than 20 cm. However, when the cutting size is less than 20 cm, the baffle needs to be reinstalled to prevent coolant from splashing. Since samples with a cutting length greater than 20 cm usually account for about 30%, the screw loading and unloading operations need to be frequently performed during work, which seriously affects the cutting efficiency and the service life of the baffle. Summary of the invention

[0020] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0021] It should be noted that the following detailed descriptions are exemplary and are intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present application belongs.

[0022] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0023] like Figure 1-4 As shown, an adjustment baffle of a metallographic cutting machine which does not need to be disassembled comprises a metallographic cutting machine 1, one side of the metallographic cutting machine is provided with an opening 4 for a sample to extend out, a sliding baffle mechanism is provided on the side of the metallographic cutting machine on the opening, the sliding baffle mechanism comprises an adjustment fixing plate 2 and an adjustment baffle 3, the adjustment baffle is slidably connected in the adjustment fixing plate, a fixing device 6 for clamping the adjustment baffle is provided above the adjustment fixing plate, and when in use, the opening is opened or closed by extending and retracting the adjustment baffle.

[0024] The cam is provided with a plurality of grooves 7 on the top and the bottom, and the grooves 8 are provided on the bottom of the grooves 8 so that the cam can slide smoothly.

[0025] In this embodiment, in order to achieve the snap connection between the fixing device and the adjusting baffle, the fixing device includes a spring pin mechanism arranged symmetrically on the left and right, and the spring pin mechanism includes a fixing seat. The spacing between the two fixing seats is not less than the width of the plate body, so that when the upper end of the plate body extends out of the sliding cavity, it can enter between the two fixing seats. The fixing seat is provided with a spring pin corresponding to the slot. When the upper end of the plate body enters between the two fixing seats, the snap connection is achieved through the cooperation of the spring pin and the slot.

[0026] In this embodiment, a more specific spring pin structure is as follows: the spring pin includes a pin shaft 10, one end of the pin shaft is installed with an insert block 9 that matches the slot, a pin hole for horizontal sliding of the pin shaft is provided on the side of the fixed seat away from the plate body, a sliding hole for horizontal sliding of the insert block is provided on the side of the fixed seat close to the plate body corresponding to the pin hole, the sliding hole is connected with the pin hole, and a spring 11 is provided on the outer sleeve of the shaft section of the pin shaft located in the sliding hole, and the two ends of the spring are respectively abutted against the insert block, the sliding hole and the pin hole connection. On the stepped surface of the joint, the other end of the pin shaft extends out through the pin hole, and a stopper 12 is installed on the protruding end. When in use, after the upper end of the plate body enters between the two fixed seats, the pin shaft is pulled out through the two stops, so that the distance between the two plug-in blocks becomes larger. Then, after the two slots at the upper end of the plate body correspond to the plug-in blocks, the stopper is released, and the plug-in block is reset under the action of the spring and presses against the slot to achieve fixation. When it needs to be released, it is only necessary to pull open the stopper to drive the plug-in block out of the slot, so that it is convenient to pull down the adjustment baffle by the handle.

[0027] In this embodiment, for reasonable design, the diameter of the insert block is larger than the diameter of the pin shaft, and the diameter of the sliding hole is larger than the diameter of the pin hole, so as to facilitate the sliding of the pin shaft and the insert block.

[0028] In this embodiment, a support 5 is provided on the lower edge of the opening to prevent the regulating baffle from excessively disengaging from the sliding cavity, and the support 5 serves to support the falling regulating baffle.

[0029] In this embodiment, the upper parts of the two fixing seats are connected by a connecting rod, and the fixing seat, connecting rod, and adjustment fixing plate are fixed on the outer casing of the metallographic cutting machine, and more specifically, are installed on the external protective cover body of the metallographic cutting machine. At the same time, the fixing method can be welding, screw connection, and other existing fixing methods, as long as the fixation can be achieved.

[0030] In this embodiment, the length of the adjusting baffle is greater than the height of the opening, and its function is to completely cover the opening, while also providing partial support and limiting effects on the adjusting baffle. The thickness of the sliding cavity is not less than the thickness of the adjusting baffle, which facilitates the up and down sliding of the adjusting baffle.

[0031] In this embodiment, when the metallographic cutting machine is used to cut the test material, if the length of the material exceeds 20 cm, the protective cover body of the metallographic cutting machine will not be completely closed. At this time, the operator can lift the adjustment baffle on the side of the protective cover body toward the fixing device by the handle. When the adjustment baffle approaches the fixing device, the operator needs to pull the pin shaft outward through the two blocks to release the restriction of the fixing device plug block on the upward movement of the adjustment baffle. Continue to lift the adjustment baffle until it completely rests against the connecting rod on the fixing device, and then release the block. At this time, due to the elastic force of the two springs on the fixing device, these springs will push the pin shaft and the plug block of the fixing device to move toward the card slot of the adjustment baffle until the end of the plug block is in close contact with the bottom of the card slot, thereby fixing the adjustment baffle. At this time, the opening is in an open state, and the cutting operation can be started. After the cutting is completed, the material is removed, and the pin shaft is operated by pulling the block of the two fixing devices to make the fixing device plug block disengage from the card slot. The adjustment baffle falls back to the support under the action of gravity, that is, the opening is closed, marking the end of the test.

Since there are too many numerical values ​​to be exhaustive, the utility model discloses only some numerical values ​​to illustrate the technical solution of the utility model, and the numerical values ​​listed above should not constitute a limitation on the scope of protection of the utility model.
