Description

Technical Field

[0001] This invention relates to the field of switching mechanism testing technology, and in particular to a flipping testing platform and testing method for switching mechanisms. Background Technology

[0002] In the field of stamping dies, the switching mechanism is a commonly used functional component, which is usually installed on the upper die and operates in an inverted state. Before leaving the factory, the function and reliability of the switching mechanism need to be tested to simulate its working state in an actual die.

[0003] Currently, testing switching mechanisms faces the following challenges: the testing process requires simulating both upright and inverted states of the switching mechanism within the mold. Traditional methods rely entirely on manual labor and hoisting equipment, first flipping the switching mechanism, then lifting and fixing it for testing. This method has the following drawbacks: 1. Poor safety: Due to the weight of the switching mechanism, manually flipping the heavy switching mechanism can easily cause safety accidents such as squeezing and crushing injuries; 2. Inefficient: The manual flipping, hoisting, and fixing process is cumbersome, time-consuming, and labor-intensive; 3. Inaccurate simulation of test conditions: Especially in the inverted state, it is difficult to effectively simulate the real weight load of the tool block, which affects the accuracy of the test results. Summary of the Invention

[0004] The purpose of this invention is to overcome the above-mentioned defects of the prior art and to provide a flip detection platform and detection method for switching mechanisms, so as to solve the technical problems of poor safety, low efficiency and inaccurate working condition simulation of existing switching mechanism testing methods.

[0005] To achieve the above objectives, the present invention provides the following technical solution: This invention designs a flip detection platform for a switching mechanism, including a frame assembly, a flip mechanism, a switching mechanism, a load simulation system, and a drive system; The frame assembly constitutes the main support structure of the flip detection platform. The upper end of the frame assembly forms a U-shaped opening, which is used to accommodate the flip mechanism, the switching mechanism, and the load simulation system. The drive system is mounted on the frame assembly, and the drive unit of the drive system is connected to the tilting mechanism to drive the tilting mechanism to tilt. The switching mechanism is mounted on the flipping mechanism, which is located at the upper end of the opening. Both ends of the flipping mechanism are connected to the two sides of the opening, and the flipping mechanism is used to drive the switching mechanism to flip so as to realize the upright and inverted testing of the flipping detection platform. The load simulation system is located at the bottom of the opening, below the switching mechanism. At the inverted test station, the load simulation system is connected to the switching mechanism and is used to simulate the functional test of the switching mechanism when it is under load at the inverted test station.

[0006] As a preferred embodiment, the flipping mechanism includes a flipping plate and a rotating shaft. The rotating shaft is disposed on the side of the flipping plate and is supported on the frame assembly by a bearing seat. The switching mechanism is disposed on the flipping plate.

[0007] As a preferred embodiment, the drive system includes a cylinder, a rack, and a gear. The cylinder is mounted on the frame assembly, the rack is connected to the piston rod of the cylinder, and the gear meshes with the rack. The gear is mounted on the rotating shaft of the tilting mechanism. The drive system is used to drive the tilting mechanism to tilt 180°. When the cylinder actuates, the meshing transmission between the rack and the gear drives the tilting plate to rotate 180° around the axis of its rotating shaft.

[0008] Furthermore, the drive system consists of two sets, symmetrically arranged on both sides of the frame assembly, to ensure the smoothness and reliability of the flipping process.

[0009] As a preferred embodiment, the load simulation system includes a vacuum suction cup, a counterweight, a connecting rod, and a vacuum generator. The vacuum generator is mounted on the frame assembly, with one end connected to the connecting rod. The vacuum suction cup and the counterweight are respectively positioned at the upper and lower ends of the connecting rod. The vacuum suction cup is used to adhere to the mounting surface of the switching mechanism in the inverted position, and the counterweight is used to simulate the weight of the actual cutting tool. The vacuum suction cup generates negative pressure through the vacuum generator, which is used to adhere to the mounting surface of the switching mechanism when it is in the inverted position. A standard counterweight is suspended below the vacuum suction cup to simulate the weight of the actual cutting tool.

[0010] As a preferred embodiment, the system also includes a pneumatic control system mounted on the frame assembly. The pneumatic control system is connected to the pneumatic actuators of the cylinder and the switching mechanism, respectively, providing them with a power source. The pneumatic control system provides power to the cylinders of the drive system and the pneumatic actuators of the switching mechanism itself.

[0011] As a preferred embodiment, the bottom of the frame assembly is provided with casters to facilitate the transportation of the flip detection platform.

[0012] As a preferred embodiment, the frame assembly is provided with a tool storage drawer on its side for easy storage of testing tools.

[0013] This invention also provides a detection method for a flip detection platform for a switching mechanism, comprising the following steps: Formal mounting test: The switching mechanism to be tested is hoisted and fixed on the flip plate in the initial position; air is supplied to the switching mechanism through the pneumatic control system, and no-load function test and load function test are performed in the formal mounting state respectively; the formal mounting state also needs to be tested under load. At this time, no suction cup or other parts are needed, and the counterweight can be placed directly on the switching mechanism to be tested.

[0014] Automatic flipping: Start the drive system, the cylinder pushes the rack, which drives the gear and flipping plate assembly to rotate, so that the switching mechanism reaches the inverted test position; there are screw holes on the flipping plate, and the switching mechanism to be tested can be locked onto the flipping plate by screws, so that it can be flipped 180° together with the flipping plate.

[0015] Load application: At the inverted position, the vacuum suction cup of the load simulation system is attached to the mounting surface of the switching mechanism, and a standard counterweight of the corresponding weight is attached. Inverted test: Drive the switching mechanism again through the pneumatic control system to perform a load-bearing inverted state function test; connect the air source, use the vacuum generator to evacuate the suction cup and attach it to the switching mechanism under test, hang the counterweight to perform a load-bearing inverted state function test.

[0016] Reset and disassembly: After the test is completed, restart the drive system to make the flip plate drive the mechanism back to the initial position; unload the load and switch the mechanism to complete the entire test cycle.

[0017] The beneficial effects of this invention are: This invention provides a flipping detection platform and method for switching mechanisms. By setting up a flipping mechanism and a load simulation system, it can safely and efficiently achieve a 180° flip of the workpiece under test, and accurately simulate its installation posture and load conditions in an actual mold. This solves the technical problems of poor safety, low efficiency, and inaccurate working condition simulation in existing switching mechanism testing methods. It has the following advantages: (1) Significantly improved safety: The mechanized and automated flipping mechanism completely replaces the dangerous manual flipping operation, fundamentally eliminating safety hazards.

[0018] (2) Significantly improved testing efficiency: By integrating the frame assembly, flipping mechanism, drive system, pneumatic control system and load simulation system into one unit and setting up moving wheels, the test station can be quickly positioned and changed. The integrated platform realizes the whole process of "fixing-forward testing-flipping-inverted testing-resetting" in one integrated operation, eliminating the frequent hoisting and flipping links, and significantly improving testing efficiency.

[0019] (3) Achieving high simulation of test conditions and accuracy of test results: For the actual working condition where the switching mechanism needs to bear the weight of the cutting block in the inverted state, an innovative load simulation method is adopted, where a vacuum suction cup assembly is attached to the mounting surface of the mechanism and a standard counterweight is suspended. This method eliminates the need to machine fixing holes on the test piece, reliably applying a load consistent with the actual weight of the cutting block, thus accurately simulating the stress conditions in the inverted state and ensuring the authenticity and effectiveness of functional and reliability testing. The innovative load simulation system, especially for the inverted state without fixing holes, uses a vacuum suction counterweight method to accurately simulate the weight load of the cutting block, making the test results more realistic and reliable.

[0020] (4) Integration and multifunctionality: The flip plate surface is equipped with matrix-style threaded holes or T-slots, which allows for flexible fixing of switching mechanisms with different sizes and mounting hole positions by bolts, improving the versatility of the platform. The platform integrates drive, pneumatic control, load simulation and tool storage functions, with a compact structure and convenient mobility, providing a complete testing solution.

[0021] (5) Good applicability and economy: The tilting plate adopts a modular design, which can be adapted to various product models. The drive system adopts two sets of cylinder-rack-gear mechanisms arranged symmetrically on the left and right sides, which synchronously drive the rotating shafts on both sides, ensuring the balance and stability of the tilting plate under load, and avoiding jamming or off-center load problems that may occur with single-point drive. The drive system uses mature and reliable pneumatic components, which are low in cost and easy to maintain. Attached Figure Description

[0047] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0048] This invention relates to a flip detection platform for a switching mechanism, the platform comprising: The frame assembly forms the main support structure of the platform and is equipped with casters at the bottom for easy transportation. One side of the frame assembly has a U-shaped opening for accommodating the flipping plate and load during the flipping process.

[0049] In one embodiment, the frame assembly also integrates a tool storage drawer.

[0050] The flipping mechanism includes a flipping plate for detachably mounting a receiving switching mechanism via clamps or bolts; rotating shafts are fixed on both sides of the flipping plate, and the rotating shafts are supported on the frame assembly via bearing seats.

[0051] In one embodiment, the flip plate has a matrix of threaded holes or T-slots on its surface to accommodate the installation of switching mechanisms of different sizes.

[0052] A drive system is used to drive the flipping mechanism to flip 180°; the drive system includes a cylinder as a power source, a rack connected to the cylinder piston rod, and a gear meshing with the rack; the gear is fixedly mounted on the rotating shaft of the flipping plate, and the gear is fixed to the rotating shaft by a key connection or interference fit; when the cylinder is actuated, the rotating plate is driven to rotate precisely 180° around its rotating shaft axis through the meshing transmission of the rack and gear.

[0053] In one embodiment, two sets of the drive system are symmetrically arranged on the left and right sides, respectively located on both sides of the two rotating shafts, to ensure the smoothness and reliability of the flipping process.

[0054] The pneumatic control system includes an air source processing component, a control valve, and pipelines; the pneumatic control system provides power air sources for the cylinders of the drive system and the pneumatic actuators of the switching mechanism under test.

[0055] The load simulation system includes a vacuum suction cup assembly and a standard counterweight. The vacuum suction cup assembly is connected to the standard counterweight via a connecting rod. The vacuum suction cup assembly generates negative pressure through a vacuum generator to adhere to the mounting plane of the switching mechanism under test when the flip plate is in the inverted position. The standard counterweight is suspended below the vacuum suction cup assembly to simulate the weight of the actual cutting block.

S4: Inverted test: The switching mechanism is driven again by the pneumatic control system to perform a load-bearing inverted state function test. S5: Reset and disassembly: After the test is completed, restart the drive system to make the flip plate rotate the mechanism 180° back to the initial position; unload the load and switch the mechanism to complete the entire test cycle.

[0058] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0059] like Figures 1 to 3 As shown, this embodiment provides a flipping detection platform for a switching mechanism. Its frame assembly 1 is welded from 45 steel, resulting in a robust structure. Four casters 11 with brakes are installed at the bottom for easy movement and positioning within the workshop. One side of the frame is designed with a U-shaped opening to provide space for the rotation of the flipping plate 21.

[0060] The flip plate 21 is made of thick steel plate, and its working surface is machined with a matrix of threaded holes for fixing the test switching mechanism 6 with different installation sizes by bolts. The flip plate 21 has a rotating shaft 22 welded to both ends, and the rotating shaft 22 is supported on the frame 1 by bearings.

[0061] The drive system 3 is symmetrically arranged on both sides of the platform. Each side is powered by a cylinder 31, with the end of the cylinder rod connected to a rack 32 via a connecting block. The rack 32 meshes with a gear 33, which is fixed to the rotating shaft 22 on the same side by a key. The pneumatic control system 4 is connected to the pneumatic actuators of the cylinder 31 and the switching mechanism 6. When compressed air enters the rodless chamber of the cylinder 31 through the pneumatic control system 4, the cylinder rod extends, pushing the rack 32 to move linearly, thereby driving the gear 33 and the rotating shaft 22 to rotate, realizing the 180° rotation of the tilting plate 21. The pneumatic control system 4 includes an air source switch, a pressure regulating valve, a branch block, quick-connect couplings, etc., which can provide independent and pressure-adjustable air sources for the tilting mechanism and the switching mechanism, as well as for the testing of the switching mechanism.

[0062] The load simulation system 5 includes a vacuum suction cup 51 and several dumbbell plates of different weights as standard counterweights 52. The vacuum suction cup 51 is connected to a vacuum generator 54 via an air tube. When the flip plate 21 is in the inverted position (e.g., Figure 2 When (as shown), press the vacuum suction cup 51 onto the smooth mounting surface of the switching mechanism 6, start the vacuum generator 54, and it can be firmly adsorbed. Then, hang the counterweight 52 of the required weight on the lower part of the suction cup through the connecting rod 53.

[0063] The working principle and process of this invention are as follows: At the start of the test, the flip plate 21 was in Figure 1 The diagram shows the upright mounting position. The operator uses a crane to lift the switching mechanism 6 to be tested onto the tilting plate 21 and secures it with bolts. The air supply is then connected, and air is supplied to the switching mechanism 6 through the control valve to perform an operational test in the upright mounting state.

[0064] After the standard test is completed, the operator presses the flip button. The reversing valve reverses, and compressed air enters the rodless chamber of cylinder 31, pushing rack 32 to move, which in turn drives gear 33 and flipping plate 21 to rotate 180° counterclockwise, reaching the desired position. Figure 2 The inverted workstation shown.

[0065] At the inverted assembly station, the operator attaches the vacuum suction cup 51 of the load simulation system 5 to the mounting surface of the mechanism 6 and hangs the counterweight 52. This simulates the working condition of the switching mechanism 6 being inverted in an actual mold and bearing the weight of the cutting tool. The switching mechanism 6 is then driven again by the pneumatic control system 4 to conduct functional and reliability tests in the inverted state.

[0066] After the inverted test is completed, the vacuum suction cup 51 is shut off, the counterweight 52 is removed, and the flip button is pressed again to rotate the flip plate 21 180° back to the initial position. The tested switching mechanism 6 is then removed. The entire testing process is safe, smooth, and efficient, requiring no manual flipping or multiple lifting operations.

[0067] The present invention has the following advantages: (1) Significantly improved safety: The mechanized and automated flipping mechanism completely replaces the dangerous manual flipping operation, fundamentally eliminating safety hazards.

[0068] (2) Test efficiency is greatly improved: The integrated platform realizes the whole process of "fixing-forward test-flipping-backward test-reset", eliminating the frequent hoisting and flipping links, and significantly improving test efficiency.

[0069] (3) Achieving high simulation of test conditions and accuracy of test results: For the actual working condition where the switching mechanism needs to bear the weight of the cutting block in the inverted state, an innovative load simulation method is adopted, where a vacuum suction cup assembly is attached to the mounting surface of the mechanism and a standard counterweight is suspended. This method eliminates the need to machine fixing holes on the test piece, reliably applying a load consistent with the actual weight of the cutting block, thus accurately simulating the stress conditions in the inverted state and ensuring the authenticity and effectiveness of functional and reliability testing. The innovative load simulation system, especially for the inverted state without fixing holes, uses a vacuum suction counterweight method to accurately simulate the weight load of the cutting block, making the test results more realistic and reliable.

[0070] (4) Integration and multifunctionality: The platform integrates drive, pneumatic control, load simulation and tool storage functions. It has a compact structure, is easy to move, and provides a complete test solution.

[0071] (5) Good applicability and economy: The flip plate adopts a modular design, which can be adapted to various models of products; the drive system adopts mature and reliable pneumatic components, which are low in cost and easy to maintain.

[0072] All other parts not described herein belong to the prior art. The embodiments described above are merely illustrative of several implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
