Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0052] Please see Figure 1-5 This utility model provides a technical solution: a laser marking machine worktable, comprising:

[0053] The platform 1 has an X-shaped sliding connection structure 2 mounted on its upper surface;

[0054] The four branches of the X-shaped sliding connection structure 2 are all slidably engaged with sliders 23;

[0055] A slider positioning assembly 7 is fixedly mounted on slider 23, and a lifting positioning fixture 4 is mounted on its upper end.

[0056] The movable parts of the left and right lifting and positioning fixtures 4 are arranged facing each other;

[0057] The X-shaped sliding connection structure 2 has a slot 3 at its center intersection, into which a vacuum suction cup seat 5 is inserted.

[0058] Specifically, in this embodiment, the platform 1 is a rectangular flat plate with a flat surface, and the X-shaped sliding connection structure 2 is located in the middle of the upper surface of the platform 1.

[0059] The shape of slot 3 matches that of vacuum suction cup base 5, so that vacuum suction cup base 5 can be stably inserted into slot 3 without leaving any gaps.

[0060] Furthermore, the X-shaped sliding connection structure 2 set on the platform 1 limits and fixes the position of each slider 23 by the slider positioning component 7 set on the upper end of the slider 23 on its four branches. The movable part of the lifting positioning fixture 4 at the upper end of the slider positioning component 7 descends and abuts against the edge of the upper surface of the object to be marked. The vacuum suction cup seat 5 in the slot 3 in the middle of the X-shaped sliding connection structure 2 is used to place the object to be marked and vacuum adsorb and fix the bottom surface of the object to be marked.

[0061] More specifically, the slider positioning component 7 is used to limit the position of the corresponding slider 23 in the four branches of the X-shaped sliding connection structure 2, and can readjust the position of the slider 23 so that the four lifting positioning fixtures 4 move accordingly, thereby meeting the fixing requirements of objects with different outer diameters to be marked within a certain range.

[0062] Understandably, this device can also be applied to other fields that require fixing the object being processed, such as drilling and welding of components.

[0063] In some embodiments, the slider positioning component 7 includes:

[0064] The first screw 71 is vertically fixed to the upper end of the slider 23;

[0065] The outer wall of the first screw 71 is screwed with a lug nut 72, which abuts against the upper surface of the platform 1.

[0066] Specifically, in this embodiment, the ear nut 72 is a nut with an outer wall that is easy to grip the ear plate. This nut is a self-locking nut to prevent loosening due to vibration after positioning.

[0067] Furthermore, the screw-on lug nut 72 abuts against the upper edge of the X-shaped slide groove 21 on the upper surface of the platform 1. The bottom surface of the lug nut 72 is rough to increase friction. The friction and extrusion force are used to limit and fix the position of the slider 23, thereby limiting and fixing the position of the lifting positioning fixture 4.

[0068] More specifically, when it is necessary to adjust the position of the lifting and positioning fixture 4, loosen the lug nut 72, slide the slider 23 to adjust the position and drive the lifting and positioning fixture 4 to move. After adjusting the position, tighten the lug nut 72 again to limit and fix the current position of the slider 23.

[0069] In some embodiments, the lifting and positioning fixture 4 includes:

[0070] A rectangular column 41, the lower end of which is fixedly assembled to the upper end of the slider positioning assembly 7;

[0071] The outer wall of the rectangular column 41 has a strip-shaped groove 42 along its length.

[0072] A second screw 43 is rotatably mounted on the bottom surface of the inner cavity of the strip groove 42, and its upper end penetrates the top surface of the strip groove 42.

[0073] One end of a pressure plate 44 is slidably fitted inside the strip groove 42, and the other end of the plate extends out of the strip groove 42.

[0074] The pressure plate 44 is located inside the strip groove 42 and is screwed to the outer wall of the second screw 43.

[0075] Specifically in this embodiment, the upper end of the second screw 43 is provided with a hand gripping round cap to facilitate the rotation operation of the second screw 43; the outer wall of the pressure plate 44 slides against the inner wall of the strip groove 42 to prevent the pressure plate 44 from rotating at an angle within the strip groove 42;

[0076] Furthermore, rotating the second screw 43 drives the pressure plate 44 screwed to it to rise and fall along the strip groove 42. The pressure plate 44 falls against the edge of the upper surface of the object to be marked. When it is necessary to remove the marked object, the pressure plate 44 can be driven to rise.

[0077] More specifically, the second screw 43 rotates clockwise to drive the pressure plate 44 to move downward; conversely, the second screw 43 rotates counterclockwise to drive the pressure plate 44 to move upward.

[0078] Understandably, the height of the pressure plate 44 is adjustable, allowing for the positioning of objects to be marked at different heights within a certain range.

[0079] In some embodiments, a rubber pad is attached to the bottom surface of the pressure plate 44 outside the strip groove 42. The rubber pad replaces the pressure plate 44 and fits against the edge of the upper surface of the object to be marked, thus avoiding wear on the object to be marked.

[0080] In some embodiments, the X-shaped sliding connection structure 2 includes:

[0081] X-shaped groove 21 is formed on the upper surface of the platform 1;

[0082] The snap-fit ​​groove 22 is formed along the length of the inner wall of the branch of the X-shaped groove 21;

[0083] The outer wall of the slider 23 has an extension block integrally formed with the corresponding snap-fit ​​groove 22, which is slidably assembled in the corresponding snap-fit ​​groove 22.

[0084] Specifically, in this embodiment, the X-shaped groove 21 is arranged symmetrically along the axis;

[0085] Furthermore, the slider 23 moves within the locking groove 22 via the extension block on the outer wall, and the slider 23 itself is slidably disposed on the inner wall of the branch of the X-shaped groove 21 where the locking groove 22 is located, thereby realizing the sliding locking setting of the slider 23 in the branch of the X-shaped groove 21. The locking referred to here means that the locking groove 22 limits the extension block in the vertical direction, so that the slider 23 cannot come out of the X-shaped groove 21. It does not mean that the slider 23 is obstructed in sliding within the X-shaped groove 21, and there is no obstruction in sliding the slider 23 within the X-shaped groove 21.

[0086] In some embodiments, the vacuum suction cup holder 5 includes:

[0087] A hollow cylinder 51 has uniformly opened adsorption through holes 52 on its top surface;

[0088] The outer wall of the hollow cylinder 51 is fixedly connected to one end of a connecting pipe 53, and the other end is connected to an external vacuum pump.

[0089] Specifically, in this embodiment, the vacuum pump is an external device that is powered on. In practical applications, a three-way valve is added to the pumping end of the vacuum pump. One end is connected to the hollow cylinder 51, the other end is connected to a normally closed solenoid valve, and the last end is used for air intake. A check valve is installed on the connecting pipeline. When an object needs to be sucked up, the vacuum pump is turned on to suck up the object to be marked through the suction through hole 52 on the hollow cylinder 51. When the vacuum pump is stopped, the check valve prevents the negative pressure from quickly returning to atmospheric pressure. When the sucked-up object needs to be released, the normally closed solenoid valve is opened to allow the hollow cylinder 51 to communicate with the outside atmosphere, thereby achieving the purpose of releasing the object.

[0090] Furthermore, the hollow cylinder 51 and the suction through holes 52 evenly arranged on its top surface are used as suction cups, and the surface of the hollow cylinder 51 is polished.

[0091] More specifically, in other embodiments, the surface of the hollow cylinder 51 is provided with a silicone layer, and the silicone layer is provided with a connecting hole corresponding to the adsorption through hole 52. The elasticity of the silicone itself reduces the gaps generated when in contact with the object, and better performs negative pressure adsorption and fixation on the object to be marked.

[0092] In some embodiments, a lifting support frame 6 is fixedly mounted on the outer wall of the platform 1 to support and fix the platform 1 and raise the height of the platform 1.

[0093] In some embodiments, the lifting support frame 6 includes:

[0094] The base 61 has a vertically fixed pole 62 on one side of its upper surface;

[0095] One end of the upright 62 is fitted with a lifting and positioning connector 64, and the other end is fixedly connected to the edge of the platform 1.

[0096] Specifically, in this embodiment, the bottom area of ​​the base 61 is larger than the bottom area of ​​the platform 1, and it provides stable support by contacting the ground. The upright 62 is a round rod, which facilitates the sliding adjustment and fixing of the lifting and positioning connector 64 on its outer wall.

[0097] In some embodiments, a limiting block 63 is fixedly mounted on the upper end of the upright 62 to limit the lifting and lowering position of the lifting and positioning connector 64 on the outer wall of the upright 62, so as to prevent it from coming off the upper end of the upright 62.

[0098] In some embodiments, the lifting and positioning connector 64 includes:

[0099] Sleeve 641 is slidably sleeved on the outer wall of upright 62;

[0100] A limit bolt 642 is screwed onto the outer wall of the sleeve 641, and its end abuts against the outer wall of the upright 62.

[0101] The outer wall of the sleeve 641 is integrally formed with a horizontal plate 643 at one end, and the lower edge of the other end is integrally formed with a mounting plate 644.

[0102] The edge of the platform 1 is inserted between the upper surface of the mounting plate 644 and the bottom surface of the adjacent horizontal plate 643;

[0103] A fixing bolt 645 is screwed onto the edge of the platform 1 at the position corresponding to the horizontal plate 643, and the lower end of the fixing bolt 645 is screwed onto the mounting plate 644.

[0104] Specifically, in this embodiment, there are multiple fixing bolts 645, which are distributed in a rectangular array to ensure the stability of the connection and fixing between the platform 1 and the mounting plate 644.

[0105] Furthermore, after the limiting bolts 642 on the outer wall of the sleeve 641 are tightened, their ends abut against the outer wall of the upright 62 to limit the position of the sleeve 641, thereby limiting the position of the platform 1. The number of limiting bolts 642 can be set multiple according to actual needs to ensure the stability of the limiting support for the platform 1.

[0106] When it is necessary to adjust the position of the platform 1, loosen the limit bolt 642, slide the height of the adjusting sleeve 641 to drive the platform 1 to rise and fall. After adjusting to the appropriate height, tighten the limit bolt 642 again to limit and fix the position of the sleeve 641.

[0107] More specifically, a rectangular groove is formed between the upper surface of the mounting plate 644 and the bottom surface of the adjacent horizontal plate 643. The edge of the platform 1 is inserted into this rectangular groove, and the bottom surface and side wall of the platform 1 are supported, thereby improving the stability of the platform 1 after it is fixed.

[0108] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
