[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model, through the arrangement of positioning rods and elastic pushing components, places the workpiece on top of several sets of positioning rods, while applying a certain downward force. The positioning rods, in contact with the workpiece surface, are then inserted downwards into the inner cavity of a circular hole, thus adapting to workpiece surfaces of different heights. Simultaneously, a groove matching the workpiece is formed at the top of the several sets of positioning rods, enabling the fixing of irregularly shaped workpieces and improving the applicability of the device. Furthermore, the return spring provides a continuous and stable upward elastic force to the push plate and positioning rods, ensuring that the positioning rods are always in close contact with the workpiece, providing stable support and positioning for the workpiece.

[0015] 2. This utility model, through the setting of the pusher, adopts a design that combines a hand-tightening bolt with an adapter rod and a push plate. The worker only needs to turn the hand-tightening bolt to easily drive the adapter rod to rotate in the adapter groove of the push plate, thereby pushing the push plate to slide. This allows for quick adjustment of the fixture's state. Furthermore, the adapter rod has a T-shaped cross-section and is rotatably inserted into the adapter groove of the push plate, ensuring that the adapter rod can stably transmit force to the push plate when the hand-tightening bolt is turned, without any detachment or displacement.

[0016] 3. With the design of the closure, when it is necessary to maintain or replace the elastic pusher or other components inside the circular hole, it is only necessary to unscrew the threaded post to easily operate inside. At the same time, disassembly and installation are very simple, without complicated tools and operating procedures, thus improving the efficiency of equipment maintenance.

[0025] 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.

[0026] Please see Figure 1-4 This embodiment provides a laser marking fixing device, including a base plate 100. The top of the base plate 100 is connected to a fixing seat 200 via a detachable fixing component. A cavity 203 is opened inside the upper part of the fixing seat 200. Several sets of circular holes 202 are opened at the bottom of the fixing seat 200 and are arranged along the height of the fixing seat 200. The several sets of circular holes 202 are arranged in a rectangular array. A push plate 401 is slidably connected to the inner cavity of each set of circular holes 202. A positioning rod 400 is fixedly connected to the top of the push plate 401. The top of the positioning rod 400 passes through the fixing seat 200 upward. A limiting component for fixing the positioning rod 400 is provided in the inner cavity of the cavity 203. A sealing component for closing the opening is provided at the lower opening of the circular hole 202. An elastic pushing component for pushing the positioning rod 400 upward is provided in the inner cavity of the circular hole 202.

[0027] The elastic pusher includes a return spring 402 disposed in the inner cavity of each set of circular holes 202. The two ends of each set of return springs 402 respectively contact the top of the corresponding side threaded post 201 and the bottom surface of each set of push plates 401. Through the arrangement of positioning rods 400 and elastic pushers, the workpiece is placed on the top of several sets of positioning rods 400, and a certain force is applied downwards. Then, the positioning rods 400 in contact with the workpiece surface are inserted downwards into the inner cavity of the circular holes 202 to adapt to workpiece surfaces of different heights. At the same time, a groove adapted to the workpiece is formed on the top of several sets of positioning rods 400, thereby fixing irregularly shaped workpieces and improving the applicability of the device. Furthermore, the return springs 402 can provide a continuous and stable upward elastic force for the push plates 401 and positioning rods 400, ensuring that the positioning rods 400 are always in close contact with the workpiece, providing stable support and positioning for the workpiece.

[0028] The bottom of the base plate 100 is fixedly provided with an anti-slip pad 103, which can increase the friction between the base plate 100 and the workbench surface and prevent the base plate 100 from shifting.

[0029] The limiting component includes a push plate 305 that slides left and right inside the cavity 203. The surface of the push plate 305 has a strip groove 304 at a corresponding position on each group of positioning rods 400. Each group of positioning rods 400 passes upward through the corresponding strip groove 304. A pusher is provided on one side of the fixing seat 200 to push the push plate 305 to one side, causing the inner wall of each strip groove 304 to abut against the surface of the positioning rod 400, thereby fixing the positioning rod 400. Through the limiting component, when the push plate 305 is pushed, the inner wall of the strip groove 304 gradually and tightly abuts against the surface of the positioning rod 400. As the compressive force increases, the positioning rod 400 is firmly fixed. This allows for precise adjustment of the fixing force on the positioning rod 400 according to actual needs. The operation is simple and quick, requiring only the pusher, providing reliable assurance for workpiece positioning in different processing scenarios.

[0030] The pusher includes a hand-tightening bolt 300 threadedly connected to the upper part of one side of the fixed base 200. The end of the hand-tightening bolt 300 is threaded through the fixed base 200 and fixedly connected to an adapter rod 301. An adapter groove 302 adapted to the adapter rod 301 is formed on the middle surface of one end of the push plate 305. The adapter rod 301 is rotatably inserted into the inner cavity of the adapter groove 302. The cross-section of the adapter rod 301 is T-shaped. Through the arrangement of the pusher, the hand-tightening bolt 300 and the adapter rod 301... The design of the push plate 305 allows the worker to easily rotate the adapter rod 301 within the adapter groove 302 of the push plate 305 simply by turning the hand-tightening bolt 300. This, in turn, pushes the push plate 305 to slide, enabling quick adjustment of the fixture's state. Furthermore, the adapter rod 301 has a T-shaped cross-section and is rotatably inserted into the adapter groove 302 of the push plate 305, ensuring that the adapter rod 301 can stably transmit force to the push plate 305 when the hand-tightening bolt 300 is turned, without any detachment or displacement.

[0031] The closure includes a threaded post 201 threadedly connected to the lower opening of the circular hole 202. With the closure, when it is necessary to maintain or replace the elastic pusher or other components inside the circular hole 202, it is only necessary to unscrew the threaded post 201 to easily operate inside. At the same time, disassembly and installation are very simple, without complicated tools and operating procedures, thus improving the efficiency of equipment maintenance.

[0032] The detachable fastener includes four sets of rectangular connecting holes 101 located at the bottom of the base plate 100. Each set of connecting holes 101 has a connecting bolt 102 inserted into its inner cavity. Each set of connecting bolts 102 passes through the corresponding side connecting hole 101 and is threaded to the bottom surface of the fixed seat 200. Through the detachable fastener, the fixture can withstand the weight of the workpiece and various external forces during the processing, ensuring the stability of the entire fixture structure and preventing displacement or shaking due to loose connections. This provides a reliable foundation for the precise processing of the workpiece. Furthermore, the design of the connecting bolts 102 makes the assembly and disassembly of the base plate 100 and the fixed seat 200 simple and quick. When it is necessary to replace the fixed seat 200 to adapt to different workpieces or to transport and store the fixture as a whole, the connecting bolts 102 can be quickly unscrewed to complete the separation and assembly of the components. This improves the flexibility and operability of the fixture and reduces the installation and maintenance time costs of the equipment.

[0033] Working principle;

[0034] First, insert four sets of connecting bolts 102 into the connecting holes 101 at the bottom of the base plate 100, and pass them upward through the connecting holes 101. Then, thread them onto the bottom surface of the fixing seat 200 to achieve a stable connection between the fixing seat 200 and the base plate 100.

[0035] Then, the workpiece is removed and placed on top of several sets of positioning rods 400. At the same time, a certain force is applied downwards, and the positioning rods 400 in contact with the workpiece surface are inserted downwards into the inner cavity of the circular hole 202 to adapt to the workpiece surface of different heights. Meanwhile, a groove that matches the workpiece is formed on the top of several sets of positioning rods 400, thereby fixing the workpiece.

[0036] At this time, tighten the hand-tightening bolt 300. When the hand-tightening bolt 300 rotates, it drives the adapter rod 301 to rotate in the adapter groove 302 of the push plate 305 and pushes the push plate 305 to slide left and right in the cavity 203. The inner wall of the strip groove 304 on the push plate 305 gradually abuts against the surface of the positioning rod 400. As the push plate 305 pushes further, the squeezing force of the strip groove 304 on the positioning rod 400 increases, thereby firmly fixing the positioning rod 400 and ensuring that the workpiece will not be displaced during the processing.

[0037] Subsequently, laser marking equipment is used to mark the surface of the workpiece;

[0038] After marking is completed, first loosen the hand-tightening bolt 300 so that the push plate 305 slides away from the positioning rod 400, releasing the fixing of the strip groove 304 to the positioning rod 400. Under the action of the return spring 402, the positioning rod 400 pops up a certain distance, making it easy to remove the workpiece.

[0039] When the return spring 402 becomes fatigued after prolonged use and needs to be replaced, first loosen the connecting bolt 102 to separate the fixing seat 200 from the base plate 100. Then locate the return spring 402 that needs to be replaced, use a tool to remove the corresponding threaded post 201 to release the restriction on the circular hole 202. At this point, remove the return spring 402, take out the new return spring 402 and insert it into the inner cavity of the circular hole 202, and screw the threaded post 201 back. Finally, use the connecting bolt 102 to fix the fixing seat 200 and the base plate 100 together.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
