DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] The terms "upper", "lower", "left", "right", "middle" and "one" used in the present invention are only for the convenience of description and are not intended to limit the scope of application of the present invention. Changes or adjustments to their relative relationships shall be deemed to be within the scope of application of the present invention without substantially changing the technical content.

[0023] Reference Figure 1-Figure 4 A double-clamping laser marking machine includes a table 1, a mounting groove 2 is opened on the surface of the table 1, and rectangular openings are symmetrically opened on the upper surface of the table 1, both of which are connected to the mounting groove 2. A slide rod 3 is installed in the rectangular opening for horizontal rotation, and a clamping component is provided on the slide rod 3. The clamping component includes two sliders 4 symmetrically slidably sleeved on the slide rod 3 and two clamping rods 17 respectively fixedly installed on the upper surfaces of the two sliders 4. The lower surface of the slider 4 is fixedly installed with an inclined plate 5 through a connecting rod, and a through opening 6 is opened on the surface of the inclined plate 5. Two first threaded rods 7 are installed for horizontal rotation in the mounting groove 2, and a sliding plate 8 is threadedly sleeved on the first threaded rod 7. A push rod 9 is symmetrically and vertically fixedly installed on the sliding plate 8. Multiple push rods 9 are respectively slidably arranged in multiple through openings 6.

[0024] An electric telescopic rod 10 is fixedly installed on the side wall of the platform 1, and a driving shaft of the electric telescopic rod 10 is fixedly installed on the placement plate 11. A sliding column 12 is vertically fixedly installed on the lower surface of the placement plate 11, and a marking mechanism 13 is provided on the sliding column 12 through a sliding member sliding sleeve (the marking mechanism 13 is disclosed in the publication number CN220838443U, and the patent name is a double-clamping laser marking machine. It is mainly composed of a fixed plate, a marking machine, a lens, etc. It is a prior art and its working principle is not described in detail here). The sliding component includes a sliding frame 14 slidably sleeved on the sliding column 12. The sliding frame 14 is fixedly connected to the marking mechanism 13. The marking mechanism 13 is controlled to move vertically by a driving assembly. The driving assembly includes a second threaded rod 15 vertically rotatably mounted on the upper surface of the placement plate 11. An L-shaped plate 16 is threadedly sleeved on the second threaded rod 15. A through-hole is opened on the upper surface of the placement plate 11, and one end of the L-shaped plate 16 is fixedly connected to the upper surface of the sliding frame 14.

[0025] The electric telescopic rod 10 can move the placement plate 11 and the marking mechanism 13 horizontally. When the marking distance between the marking mechanism 13 and the workpiece needs to be adjusted, the second threaded rod 15 can be rotated to control the L-shaped plate 16 to move the marking mechanism 13 vertically, thereby changing the marking distance between the marking mechanism 13 and the workpiece.

[0026] Two pairs of clamping rods 17 form two clamping marking stations, which can fix two workpieces to be marked respectively. When the marking mechanism 13 completes the marking of one workpiece and moves to mark the other workpiece, the operator can remove the marked workpiece and replace it with a new one without stopping the machine, thereby improving the marking efficiency.

[0027] Before marking, first place the two workpieces to be marked in the two clamping marking stations respectively, that is, place the workpieces between the two clamping rods 17 in the clamping marking station, and then at this time, by rotating the first threaded rod 7, control the sliding plate 8 to move with the two push rods 9, and the two push rods 9 will slide in the two openings 6 respectively, and the surface of the push rod 9 will slide in contact with the wall of the opening 6. Under the action of the inclined pressure, when the sliding plate 8 moves toward the installation groove 2, the two clamping rods 17 will approach each other, and when the sliding plate 8 moves out of the installation groove 2, the two clamping rods 17 will move away from each other until the two clamping rods 17 are tightly against the two sides of the workpiece, the workpiece can be fixed, and spaces of different sizes can be clamped and positioned quickly.

[0028] When the fixation needs to be released, the first threaded rod 7 is rotated to control the two clamping rods 17 to move away from each other until the clamping rods 17 no longer abut against the side wall of the workpiece. The clamping of the workpiece can be released and the workpiece can be removed. It is convenient and quick.

[0029] A third threaded rod 18 is vertically rotatably mounted on the upper surface of a clamping rod 17 in each set of clamping components, and a rectangular plate 19 is threadedly sleeved on the third threaded rod 18. A stop block 20 is fixedly mounted on the lower surface of the rectangular plate 19 through a connecting rod. The rectangular plate 19 is restricted in rotation by a limiting component, which includes a U-shaped seat 21 rotatably sleeved on the third threaded rod 18. The bottom of the U-shaped seat 21 is fixedly connected to the upper surface of the clamping rod 17, and the surface of the rectangular plate 19 is in sliding contact with the surface of the U-shaped seat 21.

[0030] When the two clamping rods 17 complete the clamping and positioning of the workpiece, the third threaded rod 18 can be rotated, and the rectangular plate 19 threadedly connected to the third threaded rod 18 will move vertically with the stop block 20 under the restriction of the U-shaped seat 21 until the stop block 20 is tightly against the upper surface of the workpiece. The two clamping rods 17 can clamp and position the workpiece horizontally, and the stop block 20 can press and position the workpiece vertically, thereby improving the stability of the fixed workpiece.

[0031] The surfaces of the clamping rod 17 and the rectangular plate 19 are both bonded with anti-slip pads, which are made of rubber. The anti-slip layer of rubber has good elasticity and viscosity, thereby increasing the friction between the clamping rod 17 and the rectangular plate 19 and the contact surface of the workpiece, and at the same time, it can also avoid damage to the workpiece surface due to clamping and pressing positioning.

[0032] In the present invention, two pairs of clamping rods 17 are used to form two clamping and marking stations, which can fix two workpieces to be marked respectively. When the marking mechanism 13 completes the marking of one of the workpieces and moves to mark the other workpiece, the operator can remove the marked workpiece and replace it with a new one without stopping the machine, thereby improving the marking efficiency. By rotating the first threaded rod 7, the sliding plate 8 is controlled to move with the two push rods 9. The two push rods 9 will slide in the two openings 6 respectively, and the surface of the push rod 9 will slide in contact with the wall of the opening 6. Under the action of the inclined surface pressure, the two clamping rods 17 will move relative to each other. When the two clamping rods 17 respectively abut against the left and right side walls of the workpiece, the clamping and positioning of the workpiece can be completed. When both clamping rods 17 do not abut against the workpiece, the clamping and positioning of the workpiece can be quickly released.

[0033] In the present invention, unless otherwise clearly specified or limited, the terms “installed”, “connected”, “connected”, “fixed” and the like should be understood in a broad sense.

[0034] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
