Description

Technical Field

[0001] The utility model relates to the technical field of positioning devices, in particular to a positioning device for a laser welding machine. Background Art

[0002] The laser welding machine is used to perform laser welding on the workpiece. During the laser welding process, a magnetic base is required to magnetically position the workpiece. A right-angle groove is opened on the magnetic base. Two workpieces are placed in the right-angle groove. The workpieces are initially positioned through the right-angle groove. Then the knob of the magnetic base is turned to rotate the magnet inside. When the two poles of the magnet are in the up and down direction, the magnetic positioning of the workpiece can be achieved. After the laser welding is completed, the knob is turned in the opposite direction so that the two poles of the magnet are in the horizontal direction to release the magnetic positioning of the workpiece. After releasing it, the welded workpiece can be removed from the magnetic base. The magnetic base with the right-angle groove is the positioning device of the laser welding machine.

[0003] When in use, a common laser welding machine positioning device utilizes the right-angle groove on the magnetic base to achieve preliminary positioning of the workpiece, and then rotates the knob on the magnetic base to achieve magnetic attraction positioning of the workpiece through magnetic force. After the positioning is completed, the workpiece can be laser welded, but the sizes of workpieces are different. When welding positioning is performed on a larger workpiece, the contact area between the inner wall of the right-angle groove on the magnetic base and the larger workpiece is smaller, making it difficult to achieve stable support for the larger workpiece, and thus difficult to achieve stable positioning of the larger workpiece. Therefore, the present application provides a laser welding machine positioning device to meet the needs. Utility Model Content

[0033] like Figure 1-Figure 7As shown, an embodiment of the utility model provides a positioning device for a laser welding machine, including a magnetic base 1, on which a right-angle groove is provided, and the right-angle groove is used to preliminarily position the workpiece. After the workpiece is preliminarily positioned, the knob on the magnetic base 1 is turned to make the magnetic base 1 generate a magnetic force to achieve magnetic positioning of the workpiece. After the magnetic positioning, the laser welding machine can be used to weld the workpiece. After the welding is completed, the knob is turned in the opposite direction to release the magnetic force of the magnetic base 1, and the welded workpiece can be removed from the magnetic base 1. Connecting components 8 are provided on both sides of the magnetic base 1, and the magnetic base 1 is detachably connected to an auxiliary support rod 2 through the connecting components 8. The connecting components 8 are used to connect the auxiliary support rod 2 to the magnetic base 1, and the bottom of the auxiliary support rod 2 is connected to the magnetic base 1. The top of the magnetic base 1 fits together, and a slide groove 5 is provided at the end of the auxiliary support rod 2 away from the magnetic base 1. A square bar 3 is provided at the end of the auxiliary support rod 2 away from the magnetic base 1. A connecting rod 4 is fixed to the side of the square bar 3 close to the auxiliary support rod 2. The connecting rod 4 is slidably connected to the inner wall of the slide groove 5. A positioning piece 6 is provided on the connecting rod 4. A positioning groove 7 is provided on the side of the inner wall of the slide groove 5. The positioning piece 6 is stuck in the positioning groove 7 to realize the positioning of the connecting rod 4. The square bar 3 and the auxiliary support rod 2 cooperate with the magnetic base 1 to achieve stable support for larger workpieces, thereby achieving stable positioning of larger workpieces. The distance between the square bar 3 and the auxiliary support rod 2 is adjusted through the cooperation of the slide groove 5 and the connecting rod 4, thereby adapting to the support and positioning of workpieces of different sizes.

[0034] like Figure 2 and Figure 3 As shown, in this embodiment, the connecting component 8 includes an insert rod 82 fixed at the bottom of the auxiliary support rod 2, and two L-shaped plates 81 are fixed on both sides of the magnetic base 1. The insert rod 82 is inserted between the two L-shaped plates 81, and the insert rod 82 is in contact with the side of the L-shaped plate 81. The insert rod 82 is inserted between two adjacent L-shaped plates 81 to achieve the connection between the auxiliary support rod 2 and the magnetic base 1. The auxiliary support rod 2 can be removed from the magnetic base 1 by pulling the insert rod 82 out from between the two adjacent L-shaped plates 81.

[0035] like Figure 2 As shown, in this embodiment, a reinforcing rib 9 is fixed to the side of the insertion rod 82, the top of the reinforcing rib 9 is fixedly connected to the bottom of the auxiliary support rod 2, and the reinforcing rib 9 is located between two adjacent L-shaped plates 81. The reinforcing rib 9 is used to increase the contact area between the insertion rod 82 and the auxiliary support rod 2, thereby increasing the connection strength between the insertion rod 82 and the auxiliary support rod 2, and preventing the auxiliary support rod 2 from deforming at the connection position between the insertion rod 82 and the auxiliary support rod 2 when the auxiliary support rod 2 is subjected to force.

[0036] like Figure 7As shown, in this embodiment, a slope 83 is provided on the side of the L-shaped plate 81, and the slope 83 is used to guide the insertion rod 82 to be inserted between the two L-shaped rods. When the insertion rod 82 is inserted between two adjacent L-shaped plates 81, the insertion rod 82 is conveniently inserted between the two adjacent L-shaped plates 81 through the guidance of the slope 83, thereby making the connection between the auxiliary support rod 2 and the magnetic base 1 simpler and more convenient.

[0037] like Figure 2 As shown, in this embodiment, the bottom of the insertion rod 82 is a downwardly curved arc surface, and the arc surface further facilitates the insertion of the insertion rod 82 between two adjacent L-shaped plates 81.

[0038] like Figure 1 As shown, in this embodiment, the central axis of the auxiliary support rod 2 is perpendicular to the central axis of the square bar 3, and the auxiliary support rod 2 and the square bar 3 form a T shape, which increases the supporting area for larger workpieces, thereby providing positioning stability for larger workpieces.

[0039] like Figure 5 As shown, in this embodiment, the connecting rod 4 is in an I-shape, and the shape of the slide groove 5 is adapted to the shape of the connecting rod 4. The I-shaped connecting rod 4 can effectively prevent the connecting rod 4 from bending and deforming due to stress, thereby improving the supporting stability of the other bar 3.

[0040] like Figure 1 As shown, in this embodiment, the two auxiliary support rods 2 are symmetrically arranged with the central vertical plane passing through the magnetic base 1 as the symmetry plane, and the two auxiliary support rods 2 jointly support and position the larger workpiece, thereby further improving the positioning stability of the larger workpiece.

[0041] like Figure 5 As shown, in this embodiment, the positioning member 6 includes a connecting block 62 arranged on the connecting rod 4, and a limiting groove 63 is provided at the top of the inner wall of the slide groove 5. The connecting block 62 is slidably connected in the limiting groove 63. A tension spring 64 and two positioning pins 61 are fixed at the bottom of the connecting block 62 respectively. The tension spring 64 is located between the two positioning pins 61. A circular groove 65 and two through holes are respectively provided on the connecting rod 4. The inner wall of the through hole is slidably connected with the circumferential surface of the positioning pin 61. The bottom of the positioning pin 61 is fitted with the inner wall of the positioning groove 7, and the bottom of the tension spring 64 is fixedly connected with the bottom of the inner wall of the circular groove 65. When the connecting block 62 is fitted with the side of the inner wall of the limiting groove 63 away from the magnetic base 1, the distance between the square bar 3 and the auxiliary support rod 2 is the largest. The limiting groove 63 is used to prevent the connecting rod 4 from separating from the auxiliary support rod 2. The connecting block 62 drives the positioning pin 61 to be stuck in the positioning groove 7 under the tension of the tension spring 64, so as to realize the positioning of the connecting rod 4, thereby realizing the positioning between the square bar 3 and the auxiliary support rod 2.

[0042] like Figure 5 and Figure 6As shown, in this embodiment, the bottom of the positioning pin 61 is a downwardly bent curved surface 1, and the inner wall of the positioning groove 7 is provided with a curved surface 2 that is adapted to the shape of the curved surface 1. Through the cooperation between the curved surface 1 and the curved surface 2, the positioning pin 61 is prevented from being stuck in the positioning groove 7 and the connecting rod 4 cannot move.

[0043] Working principle: insert the insertion rod 82 at the bottom of the auxiliary support rod 2 between two adjacent L-shaped plates 81, so that the bottom of the auxiliary support rod 2 fits with the top of the magnetic base 1 to achieve the positioning of the auxiliary support rod 2. The auxiliary support rod 2 and the square bar 3 increase the support area for larger workpieces. Then turn the knob on the magnetic base 1 to achieve magnetic positioning of larger workpieces, thereby achieving stable positioning of larger workpieces. The square bar 3 can be moved to adjust the distance between the square bar 3 and the auxiliary support rod 2. When the square bar 3 moves, it drives the connecting rod 4 to move along the inner wall of the slide groove 5. The connecting rod 4 drives the positioning pin 61 to move, and the curved surface of the inner wall of the positioning pin 61 is squeezed. The curved surface 1 at the bottom of the positioning pin 61 is pressed, so that the positioning pin 61 moves upward along the inner wall of the through hole and drives the connecting block 62 to move upward. The connecting block 62 drives the tension spring 64 to be in a stretched state, and the positioning pin 61 is separated from the positioning groove 7. After separation, the distance between the square bar 3 and the auxiliary support rod 2 is adjusted to a suitable distance. The connecting block 62 drives the positioning pin 61 to be inserted into the corresponding positioning groove 7 under the tension of the tension spring 64. At the same time, the distance between the square bar 3 and the auxiliary support rod 2 is adjustable, so as to realize the positioning of the connecting rod 4, thereby realizing the positioning of the square bar 3. The distance between the square bar 3 and the auxiliary support rod 2 is adjustable, so as to adapt to the use of workpieces of different sizes.

[0044] When the auxiliary support rod 2 is not needed, move the auxiliary support rod 2 upward, take out the insertion rod 82 from between two adjacent L-shaped plates 81, and then remove the auxiliary support rod 2 from the magnetic base 1. You can choose whether to use the auxiliary support rod 2 according to your needs to meet the actual needs of the user.

[0045] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, the specific details are described in detail in the above preferred embodiments of the present invention, and those skilled in the art can fully understand the present invention without the description of these details.

[0046] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
