Description

Technical Field

[0001] This utility model relates to the technical field of transformer processing equipment, specifically an adjustable positioning fixture for a laser marking machine. Background Technology

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are the primary coil, the secondary coil, and the iron core (magnetic core). Its main functions include voltage transformation, current transformation, impedance transformation, isolation, and voltage stabilization (magnetic saturation transformer).

[0003] After transformer production, laser marking machines are typically used to print transformer information onto the transformer. Current laser marking machines require the transformer to be positioned before marking. Currently, the transformer positioning method involves fixing at least three positioning blocks (rods) to a perforated base plate using positioning bolts to form a concave placement groove. The transformer is then placed sequentially into this groove, with the positioning blocks (rods) serving to position the transformer. However, this method requires adjusting the position of the concave placement groove according to the transformer's dimensions and the marking area. Therefore, appropriately sized positioning blocks (rods) must be selected to assemble the new groove. It's not possible to directly adjust the groove based on the transformer's dimensions and the marking area, making operation inconvenient and inefficient. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-3This utility model provides a technical solution: an adjustable positioning fixture for a laser marking machine, comprising two parallel horizontal bars 1, with fixed seats 2 at both ends of the horizontal bars 1, and two symmetrically arranged sliding sleeves 5 slidably arranged on the horizontal bars 1. A limiting rod 51 is connected between the two sliding sleeves 5 on the same side, and two main positioning plates 7 are slidably arranged on one of the limiting rods 51, with corresponding grooves 71 on the surfaces of the two main positioning plates 7. A secondary positioning plate 8 is slidably arranged on the other limiting rod 51 and slidably connected to the groove 71. The limiting rod 51, the main positioning plate 7 and the secondary positioning plate 8 form a U-shaped fixture to clamp and position the placed transformer, and a locking element is provided on the horizontal bars 1.

[0019] Furthermore, the upper surface of the fixing seat 2 is provided with positioning holes, which facilitates fixing the fixing seat 2 to the perforated base plate of the laser marking machine by means of insert rods or bolts.

[0020] Furthermore, the locking component includes a threaded cylinder 3 that is slidably mounted on the crossbar 1. The side of the threaded cylinder 3 is provided with an elastic band 6 that is connected to the sliding sleeve 5. The elastic band 6 pulls the corresponding sliding sleeve 5 to move on the crossbar 1. The sliding sleeve 5 drives the limiting rod 51 to move, and the limiting rod 51 positions the transformer.

[0021] Furthermore, a connecting rod 52 is rotatably mounted on the sliding sleeve 5. The end of the connecting rod 52 away from the sliding sleeve 5 is connected to a connecting seat 4. A locking bolt 41 is rotatably mounted on the connecting seat 4, and the lower end of the locking bolt 41 can be threadedly connected to the threaded cylinder 3. Rotating the locking bolt 41 separates it from the threaded cylinder 3. At this time, the elastic band 6 pulls the corresponding sliding sleeve 5 to move on the crossbar 1. The sliding sleeve 5 drives the limiting rod 51 to move, and the limiting rod 51 positions the transformer.

[0022] Furthermore, a fastening bolt 31 is threaded into the threaded hole on the side of the threaded cylinder 3. Initially, the locking bolt 41 is threadedly connected to the threaded cylinder 3. Moving the threaded cylinder 3 along the crossbar 1 causes the threaded cylinder 3 to move the connecting seat 4 via the locking bolt 41. The connecting seat 4 then moves the sliding sleeve 5 via the connecting rod 52. The sliding sleeve 5 moves the limiting rod 51. Finally, rotating the fastening bolt 31 positions the threaded cylinder 3. The position of the central axis of the threaded cylinder 3 is the symmetry axis of the fixture.

[0023] Furthermore, the screw holes on the side of the main positioning plate 7 are threaded with positioning bolts 72. When one of the main positioning plates 7 moves along the sliding sleeve 5, the main positioning plate 7 drives the corresponding secondary positioning plate 8 to move and rotates the corresponding positioning bolts 72 to position the main positioning plate 7.

[0024] When using:

[0025] Adjust the centering position of the clamp according to the size of the transformer. The adjustment method is as follows:

[0026] In the initial stage, the locking bolt 41 is threadedly connected to the threaded cylinder 3. The threaded cylinder 3 moves along the crossbar 1. The threaded cylinder 3 drives the connecting seat 4 to move through the locking bolt 41. The connecting seat 4 drives the sliding sleeve 5 to move through the connecting rod 52. The sliding sleeve 5 drives the limiting rod 51 to move. Then, the fastening bolt 31 is rotated to position the threaded cylinder 3. The position of the central axis of the threaded cylinder 3 is the position of the symmetry axis of the fixture.

[0027] Then, one of the main positioning plates 7 is moved along the sliding sleeve 5. The main positioning plate 7 drives the corresponding auxiliary positioning plate 8 to move, and the corresponding positioning bolt 72 is rotated to position the main positioning plate 7.

[0028] The transformer positioning method is as follows:

[0029] The transformer is placed between two main positioning plates 7 in a row and column arrangement. The main positioning plate 7 that is not locked by the positioning bolt 72 is moved so that the main positioning plate 7 drives the corresponding auxiliary positioning plate 8 to tighten the transformer. The corresponding positioning bolt 72 is rotated to position the main positioning plate 7.

[0030] Rotate the locking bolt 41 to separate it from the threaded cylinder 3. At this time, the elastic band 6 pulls the corresponding sliding sleeve 5 to move on the crossbar 1. The sliding sleeve 5 drives the limit rod 51 to move, and the limit rod 51 positions the transformer.

[0031] Furthermore, during the movement of the limiting rod 51, the secondary positioning plate 8 is inserted into the corresponding slide groove 71. At this time, the limiting rod 51, the main positioning plate 7, and the secondary positioning plate 8 form a U-shaped clamp to tighten and position the placed transformer. Then, the transformer can be marked to meet the standard by an external laser marking machine.

[0032] When placing the transformer, the transformer can be placed in a horizontal arrangement on a support plate of a certain size. Then, the support plate with the transformer is placed between two main positioning plates 7 and two limiting rods 51. By replacing the support plate with the transformer, the positioning and marking of this part of the transformer can be completed quickly, thereby improving work efficiency.

[0033] After marking is completed, press the locking bolt 41 and thread the locking bolt 41 to the threaded cylinder 3. During the process of the locking bolt 41 driving the connecting seat 4 to move down, the connecting seat 4 drives the sliding sleeve 5 to move along the crossbar 1 through the connecting rod 52. Then, move one of the main positioning plates 7 to remove the transformer.

[0034] This invention can adjust the size of the U-shaped clamp and the center of the clamp according to the size of the transformer without disassembly or replacement. It is easy to operate and can quickly position multiple transformers placed in rows and columns, which helps to quickly mark the transformers and can effectively improve work efficiency.
