Description

Technical Field

[0001] The invention belongs to the technical field of workpiece detection, and in particular relates to a multi-angle impact detection device for the surface of an aluminum profile. Background Art

[0002] Existing metal workpiece impact testing equipment is usually large in size and complicated to operate, and the workpiece needs to be cut to a specified size and fixed on a fixture before the impact test can be performed. This method not only makes the testing process cumbersome, but also easily causes destructive damage to workpieces with complex structures, such as aluminum profile alloys. Aluminum profile alloys are often designed to be more complex in order to improve the supporting strength, and the surface is not a smooth plane, so it is difficult for traditional testing equipment to perform effective strength impact tests on them. In addition, since the strength of aluminum profiles is usually lower than that of steel, when performing local structural testing on them, it is easy to cause sample deformation or damage due to cutting or fixing, resulting in distorted test data. Therefore, the limitations of existing equipment make it impossible to achieve convenient and accurate testing from multiple angles in the impact test of some complex structure alloy workpieces, especially for internal strength testing of parts that need to go deep into narrow gaps, traditional equipment cannot meet the needs.

[0003] In view of this, the present invention is proposed. Summary of the invention

[0004] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

The transmission design of the active gear and the driven gear ensures the stability of the rotating component at high speed. Under the control of the inertial force and the instantaneous pause, the impact component can concentrate on applying two-stage impact force in a very short time. The overall force concentration is extremely high, and there is no obvious reaction force on personnel, which ensures stability in the handheld state. At the same time, some larger workpieces can be directly impact tested, which is convenient and safe to operate and easy to use.

[0007] The counterweight design effectively offsets the centrifugal force, reduces the hand-held load, and improves the grip stability. In addition, the device achieves energy accumulation and transmission through the cooperation of the lock buckle and the locking plate, making the impact process more efficient and accurate, and solving the problems of large size, complex operation, and unstable detection of traditional equipment. In short, this solution has the advantages of miniaturization, convenient operation, no reaction force, and concentrated impact force, and realizes fast and accurate impact detection of metal workpieces.

[0008] Preferably, the rotating core group includes a rotating drum that penetrates and rotates on one side of the shell, a clamp is sleeved on the surface of the rotating drum, a rotating member is installed between the clamp and the rotating drum, and the surface of the rotating member is fixedly connected to the inner wall of the inertial rotating assembly.

[0009] Preferably, the limit assembly includes a lateral limit block that penetrates and slides on one side of the shell, one side of the lateral limit block is fixedly connected to a pressure cylinder, one end of the pressure cylinder is fixedly connected to a slapping plate, the slapping plate and the opposite surface of the shell are commonly fixedly connected to a spring, and the surface of the slapping plate is fixedly connected to one end of the cooperative assembly;

[0012] Preferably, the cooperative component includes a sliding shaft axially penetrating and sliding on the inner wall of the rotating drum, one end of the sliding shaft is installed with a pressure plate through a bearing, one side of the pressure plate is fixedly connected to a pressure ring that cooperates with the groove ring, and the surface of the pressure plate is fixedly connected to a locking plate.

[0013] Preferably, the impact assembly includes a pin seat fixedly connected to the arc-shaped side wall of the retaining ring, the inner wall of the pin seat is movably connected to a swing arm through a pin shaft, one end of the swing arm is fixedly connected to a first impact block, and one side of the swing arm is fixedly connected to a lock buckle.

[0017] Preferably, ventilation windows are symmetrically provided on both sides of the shell, and handles are fixed on both sides of the shell.

[0018] Beneficial effects:

[0019] Traditional impact testing equipment usually requires cutting and fixing of metal workpieces to ensure the stability and accuracy of impact testing. For metal materials with complex structures, cutting often damages the integrity of the workpiece, which in turn affects its true strength test results. This solution designs a portable impact testing device that can perform multi-angle impact tests without cutting the workpiece. It is particularly suitable for the detection of complex surface structures and large-sized workpieces, greatly simplifying the operation process and improving detection efficiency.

[0020] The impact assembly of this solution generates kinetic energy through inertial rotation, and the swing arm is in a locked state when rotating. The energy accumulation and release are achieved through the cooperation of the lock buckle and the locking plate. When the slap plate is pressed down, the transmission state is interrupted, and the inertial rotation assembly relies entirely on its stored energy to perform efficient impact testing. This design enables the device to further concentrate energy after the pin seat and the lateral limit block release an impact force, ensuring the accuracy of the impact force, keeping the rotation energy storage force and the inertial force both released in one position to achieve superimposed force, and avoiding impact deviation or energy dispersion caused by inertia or reaction force in traditional equipment. In addition, the instantaneous pause design of the impact assembly enables it to complete the impact action under precise control, further improving the accuracy of detection.

DETAILED DESCRIPTION

[0035] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention.

[0036] like Figures 1 to 11 As shown, the aluminum profile surface multi-angle impact detection equipment includes:

[0037] A gear box 2 is fixedly connected to one side of the housing 1;

[0038] The detection port 8 is fixed through the arc-shaped side wall of the housing 1 and is used to locate the impact position and the impact force transmission;

[0039] The inertial rotation component 6 is rotatably arranged on the inner wall of the housing 1, and is used for high-speed rotation and accumulation of kinetic energy;

[0040] The impact assembly 7 is fixedly connected to the surface of the inertial rotating assembly 6, and is used for secondary release of inertial force after the kinetic energy of the inertial rotating assembly 6 is released;

[0041] The rotating core group 4 penetrates and rotates on one side of the inner wall of the housing 1 to support the rotation cooperation of the inertial rotating component 6;

[0042] The cooperative component 5 is disposed on one side of the inertial rotating component 6 and the rotating core group 4, and the cooperative component 5 penetrates and slides on the inner wall of the rotating core group 4;

[0043] The driving assembly 3 is fixedly connected to the surface of the gear box 2 and is used for power input control of the rotating core group 4;

[0044] The limiting component 9 penetrates and slides on one side of the housing 1 to block the movement path of the impact component 7;

[0045] A plurality of slide grooves 10 are provided on one side of the rotating core group 4 close to the cooperative component 5, and a plurality of sliders 11 for sliding in cooperation with the slide grooves 10 are fixedly connected to the surface of the cooperative component 5;

[0046] Traditional impact testing equipment can only perform impact tests at a single angle or in a specific direction when facing workpieces with complex structures, making it difficult to fully evaluate the impact resistance of the workpiece. The detection port 8 of this solution is designed with a flexible guide rod 82 structure that can contact the plane of the workpiece at any angle and perform multi-angle impact tests. This design expands the application range of the device and can more comprehensively evaluate the mechanical properties of the workpiece, especially for metal materials with complex structures.

[0047] The above scheme provides a portable impact detection device, which is suitable for the detection of complex structures and large-sized metal workpieces. It can perform multi-angle impact tests without cutting the workpiece, simplifying the operation process and improving the detection efficiency. The device accumulates kinetic energy through the inertial rotation component 6, and interrupts the transmission process when the clapping plate 91 is pressed down, so as to achieve efficient impact force release. This design ensures the concentration and accuracy of the impact force, avoiding impact deviation caused by inertia or reaction force. The instantaneous pause design of the impact component 7 further improves the detection accuracy, allowing the device to achieve energy superposition and precise control of impact testing at a specific position.

[0048] The tachometer 12 is fixed through the upper surface of the gearbox 2 and is used to monitor and display the speed of the drive assembly 3. The tachometer 12 enables the operator to grasp the internal kinetic energy storage in real time, and then implement the impact test after reaching the energy storage range.

[0049] Specifically, Figure 6 As shown: the rotating core group 4 includes a rotating drum 41 that penetrates and rotates on one side of the shell 1, and a clamp 42 is sleeved on the surface of the rotating drum 41. A rotating member 43 is installed between the clamp 42 and the rotating drum 41, and the surface of the rotating member 43 is fixedly connected to the inner wall of the inertial rotating component 6.

[0050] The rotating drum 41 of the rotating core group 4 and the clamp 42 on the surface cooperate to clamp and fix the rotating part 43 on the surface. The rotating part 43 is a rotating structure composed of multiple bearings. When necessary, it can be easily replaced by disassembling the rotating drum 41 and the clamp 42. At the same time, the rotating part 43 can meet the need for the inertial rotating component 6 to rotate freely without interference.

[0051] Specifically, Figure 8 , Figure 5 and Fig. 9As shown: the limit assembly 9 includes a lateral limit block 93 that penetrates and slides on one side of the housing 1, one side of the lateral limit block 93 is fixedly connected to a pressure cylinder 92, one end of the pressure cylinder 92 is fixedly connected to a slapping plate 91, the slapping plate 91 and the opposite surface of the housing 1 are fixedly connected to a spring 94, and the surface of the slapping plate 91 is fixedly connected to one end of the cooperative assembly 5;

[0052] By setting the lateral limit block 93, when in use, as the slap plate 91 presses the lateral limit block 93 through the pressure cylinder 92, the lateral limit block 93 slides into the inner wall of the shell 1 and blocks the movement trajectory of the pin seat 71, so that the pin seat 71 can hit one side of the lateral limit block 93, wherein the impact force exerted on the lateral limit block 93 is transmitted to the shell 1, and the force is transmitted to the guide sleeve 81 and the guide rod 82 via the shell 1, so that the hand load is lower and is directly output to the end of the guide rod 82, and when the finger releases the slap plate 91, the slap plate 91 moves with the pressure cylinder 92 under the action of the spring 94, so that the lateral limit block 93 slides out of the inner wall of the shell 1 and resets.

[0053] The lateral limit block 93 includes two forms: rectangular or circular. Figure 8 The solid metal shown has extremely high impact resistance and wear resistance. If a round shape is used, a rotating sleeve is installed on the surface, which can not only avoid repeated single-sided impact during rotation during each collision, but also facilitate the replacement of the rotating sleeve to reduce the wear of the lateral limit block 93.

[0054] One end of the pressure cylinder 92 is threadedly fitted with a tension bolt 18 , and the tension bolt 18 and the opposite surface of the lateral limit block 93 are jointly fixed with a vibration spring wire 16 , and a conductive bushing 17 is provided through the surface of the vibration spring wire 16 , and the conductive bushing 17 is embedded and fixed on the inner wall of the pressure cylinder 92 .

[0055] When the lateral limit block 93 is hit, the vibration spring wire 16 fixed on one side of the lateral limit block 93 starts to vibrate and contacts the inner wall of the conductive bushing 17, so that it is electrically connected and the driver 31 is turned off by the electrical signal. When the driver 31 is not turned off after the clapping plate 91 is manually pressed, the driver 31 can be shut down by the electrical signal fed back by the vibration. At the same time, the present invention adopts the impact point detected by the end contact of the guide rod 82. If there is an instantaneous displacement or an external force impact, the impact point position of the guide rod 82 will be displaced. At this time, the vibration spring wire 16 contacts the conductive bushing 17 under the action of displacement or impact, so that the driver 31 is shut down to avoid impact operation at the wrong position. When the present invention is used, if the hand is not stable and falls or hits other objects, the driver 31 will be shut down to ensure the safety of operation.

[0056] By further rotating the tension bolt 18, the tension on the vibration spring wire 16 can be adjusted through the tension bolt 18, so as to adjust the vibration amplitude of the vibration force it is subjected to.

[0057] Specifically, Figure 4 and Figure 6 As shown: the inertial rotating assembly 6 includes a base 61 fixedly connected to the surface of the rotating member 43, the base 61 is annularly interference fit on the surface of the rotating member 43, a retaining frame 62 is fixedly connected to the surface of the base 61, a groove ring 63 is fixedly connected to one side of the base 61, a retaining ring 64 is fitted on the inner wall of the retaining frame 62, and the surface of the retaining ring 64 is fixedly connected to the impact assembly 7.

[0058] By setting up the base 61, the base 61 serves as a rotating support to maintain a stable and fixed rotational fit with the rotating member 43. When the base 61 rotates, the retaining frame 62 on the surface rotates simultaneously. The retaining frame 62 is made of rubber, and the retaining ring 64 on its inner wall rotates synchronously under the friction force of the retaining frame 62. If the retaining ring 64 suddenly stops or the base 61 suddenly accelerates, the friction force of the retaining ring 64 can be transmitted through the retaining frame 62. At the same time, the retaining frame 62 can reduce the conduction of the vibration force of the retaining ring 64.

[0059] Specifically, Figure 7 As shown: the cooperative component 5 includes a sliding shaft 51 axially penetrating and sliding on the inner wall of the rotating drum 41, one end of the sliding shaft 51 is installed with a pressure plate 52 through a bearing, one side of the pressure plate 52 is fixedly connected with a pressure ring 53 that cooperates with the groove ring 63, and the surface of the pressure plate 52 is fixedly connected with a locking plate 54.

[0060] The sliding shaft 51 can move axially with the pressure plate 52 under the action of the slap plate 91. The pressure plate 52 slides axially in the slide groove 10 under the action of the surface slider 11, but the slider 11 will not slide out of the slide groove 10. The pressure plate 52 can maintain continuous rotation transmission while moving.

[0061] Specifically, Figure 5 As shown: the impact assembly 7 includes a pin seat 71 fixedly connected to the arc-shaped side wall of the retaining ring 64, the inner wall of the pin seat 71 is movably connected to a swing arm 72 through a pin shaft, one end of the swing arm 72 is fixedly connected to a first impact block 73, and one side of the swing arm 72 is fixedly connected to a lock buckle 74.

[0062] By setting the pin seat 71 of the impact assembly 7 in contact with the lateral limit block 93, the kinetic energy of the high-speed rotation of the retaining ring 64 is instantly stopped, and the stored energy is transmitted to the shell 1 through the lateral limit block 93, and then transmitted to the detection port 8 by the shell 1, and the impact force is applied to the contact surface of the workpiece through the guide rod 82. At the same time, the first impact block 73 at the end of the swing arm 72 of the impact assembly 7 is thrown out under the action of inertia, and the swing arm 72 swings around the pin seat 71 through the pin shaft until the first impact block 73 hits the surface of the second impact block 84, and the potential energy is transmitted to the position of the guide rod 82. In this way, the stored energy can be released in sections to avoid displacement of the contact surface of the guide rod 82 caused by excessive energy released in a single time. Through two releases, the surface deformation of the workpiece can be achieved during the first impact, and the positioning can be maintained when the second impact has a larger force, thereby ensuring the stability of the detection.

[0063] Specifically, Figure 4 As shown: the driving assembly 3 includes a driver 31 fixedly connected to one side of the gear box 2, the output shaft of the driver 31 penetrates and rotates on the inner wall of the gear box 2, and the output shaft of the driver 31 is fixedly connected to a driving gear 32, the surface of the driving gear 32 is meshed with a driven gear 33, and the driven gear 33 is fixedly connected to one end of the rotating drum 41.

[0064] By providing the driving assembly 3, the driver 31 rotates with the driven gear 33 through the driving gear 32, so that it can achieve a larger transmission ratio and maintain a higher rotation speed.

[0065] Specifically, Figure 5 As shown: the detection port 8 includes a guide sleeve 81 that passes through and is fixed on the arc-shaped side wall of the shell 1, and a guide rod 82 slides through the inner wall of the guide sleeve 81. A tension spring 83 is fixed to the surface of the guide rod 82 and one end of the guide sleeve 81, and one end of the guide rod 82 is fixedly connected to a second striking block 84.

[0066] The guide sleeve 81 of the detection port 8 is located and fixed on the surface of the shell 1, and one side of it contacts with a guide rod 82, which can transmit the force of the shell 1 to the position of the guide rod 82. At the same time, the guide rod 82 is not only subjected to the pressure of the guide sleeve 81, but also when the second impact block 84 at one end of the guide rod 82 is hit by the first impact block 73, the guide rod 82 can slide on the inner wall of the guide sleeve 81, and with the change of the length of the tension spring 83, the guide rod 82 can move a certain distance, thereby realizing the coordination of different forces in the two impact processes.

[0067] The end of the guide rod 82 includes cone, arc, plane, square and strip settings, which are respectively used for cone puncture test, arc surface hardness impact test, plane impact bending test, square tilt scratch test and strip cutting test.

[0068] Specifically, Figure 4As shown: the surface of the clamping ring 64 is fixedly connected with a weight plate 13 for balancing the impact assembly 7, and the retaining frame 62 is made of rubber.

[0069] By setting the counterweight plate 13, the counterweight plate 13 is fixedly connected to the surface of the retaining ring 64, and the counterweight plate 13 is circular with the retaining ring 64. The impact assembly 7 on the other side can be symmetrical with it and achieve dynamic balance when the swing arm 72 is attached to the surface of the retaining ring 64.

[0070] Specifically, Figure 2 As shown: ventilation windows 14 are symmetrically provided on both sides of the shell 1 , and handles 15 are fixed on both sides of the shell 1 .

[0071] When the swing arm 72 is swung out at high speed, if the airflow in the moving direction cannot flow quickly, air pressure will be formed to affect the high-speed movement of the swing arm 72. The air in the moving direction of the swing arm 72 can flow out quickly through the ventilation window 14, so that the movement of the swing arm 72 remains at a high speed.

[0072] When the present solution is used, the handle 15 is held, and the end of the guide rod 82 of the detection port 8 is brought into contact with a plane of any angle of the workpiece, and the driving assembly 3 is started while maintaining this state. First, the driving assembly 3 rotates with the driven gear 33 through the driving gear 32, and at the same time, the driven gear 33 rotates with the rotating core group 4. When the rotating drum 41 and the clamp 42 of the rotating core group 4 rotate, the rotating member 43 on the surface maintains its rotation support, and keeps the rotating core group 4 and the inertial rotating assembly 6 from interfering with each other in internal and external rotation.

[0073] In the above process, the cooperative component 5 is always in a state of pressing the rotating core group 4 and the inertial rotating component 6 under the action of the spring 94 of the limiting component 9, wherein the slider 11 on one side of the cooperative component 5 slides in the slide groove 10 at one end of the rotating cylinder 41 (such as Figure 7 As shown), when the rotating drum 41 rotates, the pressure plate 52 rotates on one end of the sliding shaft 51 through the cooperation of the sliding groove 10 and the sliding block 11. At the same time, a pressure ring 53 is fixed on the edge of the pressure plate 52, and the pressure ring 53 is in a fitting state with the groove ring 63 on one side of the inertial rotating component 6. With the force applied by the spring 94, the pressure plate 52 serves as a power transmission bridge between the rotating core group 4 and the inertial rotating component 6;

[0074] At this time, the driving component 3 drives the rotating core group 4 to rotate, and transmits the power through the cooperative component 5 to bring the entire inertial rotating component 6 and the rotating core group 4 into a synchronous rotating state (at this time, there is no speed difference between the inertial rotating component 6 and the rotating core group 4, and the rotating member 43 keeps rotating together), and the impact component 7 on the surface of the inertial rotating component 6 revolves around it as it rotates, wherein the lock buckle 74 on one side of the impact component 7 is always attached to the inner wall of the locking plate 54, and the locking plate 54 is fixed on the surface of the pressure plate 52, and rotates synchronously with the impact component 7, and there is no speed difference between them and no wear will occur. At the same time, the weight plate 13 offsets the centrifugal force of the impact component 7 on one side of the inertial rotating component 6, so as to maintain the stability of the overall rotation and reduce the load on the handheld;

[0075] When the tachometer 12 detects that the speed of the driven gear 33 reaches the preset speed range, the inertial rotation component 6 has reached the preset energy storage rotation speed. The fingers holding the handle 15 directly tap or press down the tapping plate 91. As the tapping plate 91 is pressed down, it first causes the sliding shaft 51 to slide axially with a small amplitude on the inner wall of the rotating drum 41, so that the pressure plate 52 set at one end of the sliding shaft 51 through the bearing rotation moves accordingly. When the pressure plate 52 moves, the slider 11 slides in the slide groove 10 but does not slide out. The pressure ring 53 and the groove ring 63 opposite to it are separated from the fitting state, thereby interrupting the transmission state. At this time, the inertial rotation component 6 rotates completely relying on its own stored rotational kinetic energy (and is in contact with the rotating core group 4 presents a speed difference, and the speed difference is maintained by the rotation of the rotating member 43). At this time, the locking plate 54 has not disengaged from the lock buckle 74. As the slap plate 91 continues to press the spring 94, the lateral limit block 93 is pressed by the pressure cylinder 92 and moved to the track of the pin seat 71. At this time, the locking plate 54 and the lock buckle 74 are at the edge. When the pin seat 71 hits the lateral limit block 93, the retaining ring 64 of the inertial rotating component 6 stops instantly. At the same time, the lock buckle 74 on one side of the swing arm 72 is disengaged from the locking plate 54 under its own centrifugal force and the inertial force of the instantaneous stop, and the first strike block 73 strikes the surface of the second strike block 84 at one end of the guide rod 82, so that the guide rod 82 transmits the impact force to the surface of the workpiece at the end and forms an impact pit.

[0076] After the impact component 7 completes a cycle of knocking, the palm leaves the clapping plate 91, so that the spring 94 resets the cooperative component 5 and the lateral limit block 93. At this time, the rotating core group 4 and the inertial rotating component 6 resume the transmission state and are driven to rotate by the driving component 3. When the impact component 7 rotates to the position above the shell 1 at a low speed, a small impact occurs when it contacts the inner wall of the shell 1, so that the swing arm 72 can be attached to the surface of the retaining ring 64 by the reaction force of the impact under low-speed rotation, and the lock buckle 74 is stuck to the inner wall of the locking plate 54, realizing reset and entering the next high-speed rotation power storage state.

[0077] This method can concentrate the overall impact force when in use, can achieve greater energy accumulation through rotation, and can realize impact detection on metal workpieces with a smaller volume. At the same time, the design adopted, whether it is the instantaneous stop impact force of the pin seat 71 on the lateral limit block 93 or the instantaneous impact force of the swing arm 72 on the guide rod 82, both impact force action directions are supported by the contact point between the guide rod 82 and the workpiece surface, the overall hand-held has no reaction force, and combined with the design of the counterweight plate 13, the overall grip is more stable, achieving greater energy accumulation and no obvious force on the hand gripping under a large impact force, which not only solves the problem of large size of the current impact equipment, but also solves the problem of hand-held stability.

[0078] This invention solves the problem that the current traditional equipment is large in size. When inspecting alloy workpieces, it is often necessary to cut them into a specified size and then fix them with a clamp 42 for impact testing. This makes it difficult to conduct effective impact tests on alloys with complex structures. For example, aluminum profile alloys are often weaker than steel and have more complex structures to improve their support. The surface is not a smooth plane. If cut, the supporting structure will be damaged, making it difficult to conduct accurate strength impact tests using traditional methods. In addition, this solution does not require cutting and can clamp larger workpieces for rapid impact tests at multiple angles. It can quickly detect the impact resistance of the workpiece under a preset impact force through deformation, bending or penetration (replacing the guide rod 82 with different shapes at the end to meet different testing needs), and can extend into some gaps to conduct strength tests on the local strength inside the structure.

[0079] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
