DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in combination with the specific embodiments of the utility model and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] The technical solutions provided by various embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0027] Reference Figures 1 to 3 As shown, the embodiment of the utility model provides a new type of marking tool for the working platform of a laser marking machine, including: a frame 1, which is installed on the working platform of the laser marking machine, the top of the frame 1 is a marking position 11, and above the marking position 11 is a marking head 8 of the laser marking machine (only the position of the marking head 8 is shown in the figure, and the laser marking machine is a prior art and is not fully shown in the figure), a circular stepped hole 12 is formed in the middle of the marking position 11 and passes through the top of the frame 1, and a rectangular groove 13 is also formed on the side of the marking position 11, the depth of the circular stepped hole 12 is adapted to the depth of the rectangular groove 13, and the circular stepped hole 12 is connected with the rectangular groove 13; a lifting platform 2 is driven by power to move longitudinally in the frame 1, and a circular groove 21 for accommodating a tensile specimen 9 is provided at the top center of the lifting platform 2, the circular groove 21 is coaxial with the circular stepped hole 12, and the depth of the circular groove 21 is half of the thickness of the lifting platform 2, so as to ensure that the tensile specimen 9 can be stably embedded or loaded into the circular groove 21;

[0028] The positioning structure 3 is installed in the circular stepped hole 12 for centering the tensile specimen 9; the flap plate 4 is movably connected in the rectangular groove 13 and moves between a first position and a second position, and a mounting groove 41 for accommodating the impact specimen 10 is provided on the flap plate 4; specifically, one end of the flap plate 4 is hinged to a side of the rectangular groove 13 close to the circular stepped hole 12, the width of the rectangular groove 13 is adapted to the width of the flap plate 4, and the depth of the rectangular groove 13 is adapted to the depth of the flap plate 4;

[0029] In this embodiment, when in the first position, the flip cover plate 4 is located so as not to block the circular stepped hole 12; when in the second position, the flip cover plate 4 blocks the circular stepped hole 12, and the mounting groove 41 is located directly above the circular stepped hole 12; thus, different methods are used to deal with different samples, as follows:

[0030] When marking the tensile test sample 9, the flip cover plate 4 needs to be moved to the first position. Since the tensile test sample 9 is mainly cylindrical, it is only necessary to put the tensile test sample 9 into the circular groove 21, and make the bottom end of the tensile test sample 9 against the bottom of the circular groove 21. Then, the height of the lifting platform 2 is adjusted so that the top end of the tensile test sample 9 (i.e., the marking part of the tensile test sample 9) moves and extends into the circular stepped hole 12. Then, the positioning structure 3 is used to center the tensile test sample 9 so that it is kept at the center of the circular stepped hole 12 and the circular groove 21. At this time, the marking part of the tensile test sample 9 is at the marking position 11 and is directly below the marking head 8. Thus, the marking operation can be carried out. After the marking is completed, the staff can directly take out the tensile test sample 9 and put in the next tensile test sample 9. This is repeated to improve the work efficiency.

[0031] When marking the impact sample 10, the shape of the impact sample 10 is generally a rectangular block. The length and width of the impact sample 10 are generally fixed, which is 55×10 mm, just matching the size of the mounting groove 41 on the flip plate 4. The thickness of the impact sample 10 is slightly different. Before marking the impact sample 10, the flip plate 4 needs to be moved to the second position. At this time, the impact sample 10 is directly placed in the rectangular groove 13 on the marking surface of the tooling, so that the marking part of the impact sample 10 can be aligned with the marking head 8. After marking, the staff can directly take out the impact sample 10 and put in the next impact sample 10, and repeat this process to improve work efficiency.

[0032] In some practical applications, the tensile specimen 9 commonly used in the factory is a specimen with a parallel section diameter of Φ10mm, a total length of 115~130mm, and two ends are M16 threads. There is also a pin hole on the end face for easy processing, and marking needs to be on the end face; the outer dimensions of the commonly used impact specimen 10 are 55×10×10mm. For impact specimens 10 of different thicknesses, gaskets can be added or removed in the installation groove 41 so that the marking part of the impact specimen 10 is at the marking position 11.

[0033] To sum up, when marking the tensile specimen 9, the tensile specimen 9 is placed vertically in the circular groove 21, and the height of the lifting platform 2 is adjusted so that the marking position of the tensile specimen 9 and the marking surface of the tooling are on the same horizontal plane, and then the tensile specimen 9 is aligned through the positioning structure 3; when marking the impact specimen 10, the flap plate 4 is moved to a horizontal position above the circular stepped hole 12, and the impact specimen 10 is placed horizontally in the mounting groove 41; the marking position 11 of the tensile specimen 9 or the impact specimen 10 is aligned with the marking head 8. After marking, the staff only needs to directly replace the tensile specimen 9 or the impact specimen 10, avoiding the complicated process of installing the tensile bar in the past, and the problem of constantly adjusting the tooling position and the height of the marking head 8 when replacing the marking product, thereby improving work efficiency.

[0034] Specifically, a fixing plate 5 is installed at the bottom of the frame 1, and at least two longitudinally extending slide bars 51 are provided on the fixing plate 5. The lifting platform 2 is provided with guide holes 22 that are slidably matched with the slide bars 51, which are mainly used to guide the lifting platform 2. In practical applications, the slide bars 51 are configured into four groups, and are respectively located at the four corners of the fixing plate 5;

[0035] A limit screw 52 is installed at the upper end of each slide bar 51. The head diameter of the limit screw 52 is larger than the diameter of the slide bar 51, generally twice the diameter of the guide slide bar 51. The limit screw 52 is used to limit the lifting platform 2 to prevent the lifting platform 2 from dislocating from the upper end of the slide bar 51.

[0036] In some practical applications, the power drive of the lifting platform 2 may adopt the following structure:

[0037] Specifically, Figure 1 and Figure 3 As shown, a transverse slide groove 23 is provided at the bottom of the lifting platform 2, and an X-shaped bracket 6 for supporting and lifting the lifting platform 2 is provided between the lifting platform 2 and the fixed plate 5, and the X-shaped bracket 6 includes two cross-distributed and hinged rods 61, and the top ends of the two rods 61 are configured as circular ends and are rollingly connected to the transverse slide groove 23 at the lower end of the lifting platform 2, wherein the lower end of one of the rods 61 is hinged to the fixed plate 5, and the lower end of the other rod 61 is suspended on the fixed plate 5; an adjustment component 7 for adjusting the angle between the two rods 61 is also provided on the side of the X-shaped bracket 6, and the height adjustment of the lifting platform 2 can be achieved by changing the angle between the two rods 61.

[0038] Specifically, the X-shaped bracket 6 is configured with two groups and is symmetrically arranged on the fixed plate 5; the adjustment assembly 7 includes a cross bar 71, an adjusting screw 72 and an adjusting bracket 73, the two ends of the cross bar 71 are respectively rotatably connected to the lower end of the other rod 61 of the two X-shaped brackets 6, and a transverse slide rail 53 is also provided on the fixed plate 5. The cross bar 71 is partially slidably arranged in the transverse slide rail 53, and the adjusting bracket 73 is installed on the frame 1 and is located next to the fixed plate 5. The adjusting screw 72 is laterally rotatably connected to the adjusting bracket 73, and the adjusting screw 72 is threadedly connected to the threaded hole 711 provided on the cross bar 71.

[0039] One end of the adjusting screw 72 away from the fixing plate 5 passes through the frame 1 to the outside of the marking tool, and an adjusting handle 74 for rotating the adjusting screw 72 is installed on the other end of the adjusting screw 72 away from the fixing plate 5 .

[0040] In this embodiment, the staff only needs to rotate the adjusting screw 72, and with the cooperation of the threaded hole 711, the cross bar 71 can be driven to move horizontally along the length direction of the transverse slide rail 53 to adjust the angle between the two rods 61, and then the height of the lifting platform 2 can be controlled to determine the height of the tensile specimen 9 to ensure that it is in a suitable marking position 11. This lifting structure is simple and easy to operate, and is provided with an adjusting handle 74, which makes it easier for the staff to adjust the height of the tensile specimen 9.

[0041] Specifically, the positioning structure 3 is configured as a positioning ring with an adjustable inner aperture, and the positioning ring is coaxially installed in the circular stepped hole 12. The structure of the positioning ring is a prior art, and reference may be made to the aperture structure of a camera shutter and the assembly structure of aperture blades. The figure only shows the approximate external structure, and its specific structure is not described here in detail; in addition, the positioning structure 3 can also be implemented using a centering structure similar to a three-jaw chuck.

[0042] Specifically, above the marking position 11 is the marking head 8 of the laser marking machine. When the flip cover plate 4 is flipped toward the circular stepped hole 12 and horizontally rests against the top of the circular stepped hole 12, the mounting groove 41 faces the marking head 8, which is convenient for marking the impact specimen 10. When switching to marking the tensile specimen 9, it is only necessary to flip the flip cover plate 4 in the other direction so that the circular stepped hole 12 and the positioning ring are exposed and face the marking head 8 of the laser marking machine.

[0043] The above description is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention shall be included in the scope of the claims of the present invention.
