Description

Technical Field

[0001] This utility model belongs to the field of frame processing technology, specifically relating to an automatic positioning frame opening mechanism. Background Technology

[0002] In the industrial production field, the frame opening mechanism is a key piece of equipment for achieving precise positioning and opening / closing of frames in the processing and assembly of various frame structures. The fixed frame of the frame opening mechanism can firmly fix the frame to be processed in the preset processing position, avoiding dimensional deviations caused by frame shaking or offset during processing.

[0003] In existing traditional frame-opening mechanisms, many operations require manual intervention during material loading and fixing, such as the lifting and positioning of the frame. Manual intervention not only reduces production efficiency but also often results in insufficient positioning accuracy. The manual lifting and positioning process is quite cumbersome, requiring operators to repeatedly adjust the frame position until they reach what they consider to be the appropriate state. This not only consumes a lot of production time and reduces production efficiency but also causes fatigue for operators due to repetitive actions over a long period of time, further exacerbating the instability of positioning accuracy. In mass production, such fluctuations in positioning accuracy can lead to inconsistent product quality, increasing the workload and difficulty of quality inspection, and also raising production costs. Utility Model Content

[0004] The purpose of this invention is to provide an automatic positioning frame opening mechanism to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic positioning frame opening mechanism, comprising:

[0006] A machine base, the top of which is equipped with a processing platform made of marble, and a vertical frame is connected to the processing platform;

[0007] A lower plate frame is slidably connected to a processing platform, and an upper plate frame is provided on the lower plate frame. The top surface of the processing platform is provided with a sliding component for driving the lower plate frame to move.

[0008] The lifting assembly is mounted on the upright frame and is used to drive the upper plate frame to rise and fall. The lower plate frame is moved to the bottom of the lifting assembly by the Y-axis servo screw linear module of the sliding assembly, so that the limiting rod connected to the surface of the upper plate frame slides into the limiting block of the lifting assembly, and the upper plate frame is driven to rise and fall by the lifting cylinder of the lifting assembly.

[0009] Preferably, the sliding component includes a guide rail, and the guide rail is provided in two sets and is respectively located on both sides of the top of the processing platform. A slider is slidably connected in the guide rail and the slider is connected to the lower plate frame.

[0010] Preferably, the Y-axis servo lead screw linear module is located between two sets of guide rails, and the Y-axis moving slide of the Y-axis servo lead screw linear module is connected to the lower plate frame.

[0011] Preferably, the lifting assembly includes a mounting frame, the mounting frame is provided in two sets and the two sets of mounting frames are respectively connected to both ends of the upright frame, and the lifting cylinder is provided in two sets and is respectively connected to the two sets of mounting frames.

[0012] Preferably, the piston rods of both sets of lifting cylinders are connected to lifting plates, and the limiting blocks are provided in two sets, with the two sets of limiting blocks respectively connected to the bottom of the two sets of lifting plates.

[0013] Preferably, the limiting rods are provided in several sets and are respectively connected to the top two sides of the upper plate frame, and the top of the limiting rods is connected to a T-shaped rod.

[0014] Preferably, the limiting block is provided with a T-shaped groove, and the T-shaped rod is slidably inserted into the T-shaped groove.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] (1) In the sliding assembly, the Y-axis servo screw linear module drives the lower plate frame to move. The servo screw transmission has high precision, and with the guiding effect of the guide rail, the lower plate frame can move accurately in the Y-axis direction, ensuring that it can accurately reach the bottom of the lifting assembly. The lifting assembly uses two sets of lifting cylinders connected to the mounting frame respectively. The two sets of lifting cylinders work synchronously to drive the lifting plate and limit block to rise and fall stably. The sliding assembly automatically drives the lower plate frame to move, and the lifting assembly automatically drives the upper plate frame to rise and fall and position. There is no need for manual intervention in the movement and lifting and positioning process of the frame. This eliminates the tedious process of repeatedly adjusting the frame position manually, greatly shortens the auxiliary time, and improves the overall production efficiency.

[0018] (2) The two sets of lifting cylinders work synchronously, driving the lifting plate and limit block to rise and fall stably, making the lifting process of the upper plate frame more stable, avoiding the frame tilting or shaking caused by uneven force on one side. The lower plate frame is connected to the guide rail by a slider, and the sliding process is smooth and stable, reducing the jamming during movement and ensuring the overall reliability of the mechanism.

[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] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed", "equipped with", "sleeved with", "connected", etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0027] This utility model provides, for example Figure 1-5 The automatically positioned frame opening mechanism shown includes:

[0028] A base 1, the top of which is provided with a processing platform 2 made of marble, and a stand 3 is connected to the processing platform 2;

[0029] The lower plate frame 4 is slidably connected to the processing platform 2 and the upper plate frame 5 is provided on the lower plate frame 4. The top surface of the processing platform 2 is provided with a sliding component for driving the lower plate frame 4 to move.

[0030] The lifting assembly is mounted on the upright frame 3 and is used to drive the upper plate frame 5 to rise and fall. The lower plate frame 4 is moved to the bottom of the lifting assembly by the Y-axis servo lead screw linear module 7 of the sliding assembly, so that the limiting rod 8 connected to the surface of the upper plate frame 5 slides into the limiting block 6 of the lifting assembly, and the upper plate frame 5 is driven to rise and fall by the lifting cylinder 9 of the lifting assembly.

[0031] The sliding assembly includes guide rails 10, which are provided in two sets and respectively located on the top sides of the processing platform 2. A slider is slidably connected inside the guide rails 10 and the slider is connected to the lower plate frame 4. The two sets of guide rails 10 are arranged in parallel and cooperate with the slider. When the slider slides inside the guide rails 10, the friction force it receives is uniform and small, which reduces the jamming and bumping phenomena during the movement. The lower plate frame 4 slides on both sides of the guide rails 10 at the same time, and the force is balanced, making the movement process more stable and smooth. This avoids the frame shaking caused by poor sliding on one side and helps to ensure the stability of the processing process.

[0032] The Y-axis servo lead screw linear module 7 is located between the two sets of guide rails 10, and the Y-axis moving slide of the Y-axis servo lead screw linear module 7 is connected to the lower plate frame 4.

[0033] The lifting assembly includes a mounting frame 11, which has two sets and is respectively connected to both ends of the upright frame 3. The lifting cylinder 9 has two sets and is respectively connected to the two sets of mounting frames 11.

[0034] Both sets of lifting cylinders 9 have lifting plates 12 connected to their piston rods. The limiting blocks 6 are provided in two sets, and the two sets of limiting blocks 6 are respectively connected to the bottom of the two sets of lifting plates 12.

[0035] The limiting rod 8 is provided in several sets and is respectively connected to the top two sides of the upper plate frame 5. The top of the limiting rod 8 is connected to a T-shaped rod 13. The limiting block 6 is provided with a T-shaped groove 14. The T-shaped rod 13 is slidably inserted into the T-shaped groove 14.

[0036] The lower plate frame 4 is connected to a number of positioning blocks 15 at its top. The upper plate frame 5 is provided with a number of positioning grooves 16 and the positioning blocks 15 are inserted into the positioning grooves 16. Through the mutual matching of the positioning blocks 15 and the positioning grooves 16, the relative horizontal displacement of the upper plate frame 5 on the lower plate frame 4 can be effectively restricted, so as to avoid loosening or displacement between the upper plate frame 5 and the lower plate frame 4, and make the two form a stable whole.

[0037] The automatic positioning frame-opening mechanism places the lower plate frame 4 stably in the initial position of the processing platform 2, with the bottom slider tightly engaged with the guide rail 10 to ensure no displacement when stationary. The upper plate frame 5 rests flat on the lower plate frame 4, and the two are pre-fixed by the positioning block 15 and the positioning groove 16 to prevent relative sliding due to slight contact. When the frame to be processed is placed in the processing groove on the surface of the upper plate frame 5, the operator controls the Y-axis servo lead screw linear module 7 through an external controller. The servo motor in the Y-axis servo lead screw linear module 7 responds, causing the lead screw of the Y-axis servo lead screw linear module 7 to start rotating at a constant speed. As the lead screw rotates, the Y-axis moving slide moves linearly along the lead screw direction, thereby driving the lower plate frame 4 to rotate. The plate frame 4 moves along the guide rail 10, causing the lower plate frame 4 to move closer to the limit block 6. When the lower plate frame 4 enters the area directly below the lifting assembly, the top of the limit rod 8 at the top of the upper plate frame 5 begins to approach the entrance of the T-slot 14 at the bottom of the limit block 6. The T-shaped rod 13 at the top of the limit rod 8 and the T-slot 14 at the entrance of the limit block 6 fit together. Under the guidance of both, the T-shaped rod 13 slowly slides into the interior of the limit block 6 along the T-slot 14. At this time, the proximity switch installed in the limit block 6 will detect that the T-shaped rod 13 has completely slid into the T-slot 14 and reached the preset positioning position. Then, it will send a control signal to the controller to control the servo motor to stop working, thereby realizing the initial connection between the upper plate frame 5 and the lifting assembly.

[0038] Once the positioning completion signal is transmitted to the controller of the lifting assembly, the controller immediately sends a start command to the lifting cylinders 9. The piston rods of both sets of lifting cylinders 9 retract, driving the limit block 6 via the lifting plate 12 to pull the upper plate frame 5 upward. When the upper plate frame 5 rises to the preset processing height, the position sensor on the lifting plate 12 sends a signal back to the controller, which immediately controls the lifting cylinders 9 to stop. The upper plate frame 5 remains stably at that height, achieving automatic lifting for subsequent processing operations. When the next instruction from the program is received, the operation is repeated. The upper plate frame 5 is lowered. At this time, the controller controls the piston rod of the lifting cylinder 9 to extend, and the lifting plate 12 drives the upper plate frame 5 to descend. When it approaches the lower plate frame 4, the positioning block 15 on the lower plate frame 4 is inserted into the positioning groove 16 in the upper plate frame 5, so that the upper plate frame 5 lands stably on the lower plate frame 4. Then, the servo motor of the Y-axis servo lead screw linear module 7 reverses, driving the Y-axis moving slide to move in the opposite direction, so that the lower plate frame 4 and the upper plate frame 5 return to the initial position along the guide slide rail 10, waiting for the next processing signal to be triggered.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
