As an important link in the automobile industry chain, the automobile parts testing industry is facing the pressure of technological upgrading and industrial transformation. It needs to continuously improve the detection accuracy and efficiency to meet the requirements of the automobile industry for quality, safety and environmental protection. The strength performance of automobile parts is an important part of automobile safety performance. Therefore, the strength testing equipment for automobile parts plays a vital role in the manufacturing and quality control of automobile parts. These devices can accurately detect the strength and durability of automobile parts under stress, ensuring that the parts can withstand the loads under various complex working conditions during the driving of the vehicle.

[0063] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0065] A detection movable port 4, the detection movable port 4 is opened on the strength detection control box 1, and a movable detection column 11 is arranged in the detection movable port 4, a push installation head 10 and a stretch push plate 12 are fixedly installed on the movable detection column 11, and the push installation head 10 and the stretch push plate 12 are vertically arranged between them;

[0066] and a strength detection mechanism, which is respectively connected to the strength detection control box 1 and the movable detection column 11, and is detachably connected to the stretching push plate 12, wherein the strength detection mechanism includes a clamping adjustment component and a detection drive component;

The clamping adjustment component is also detachably connected to the stretching push plate 12. The detection drive component is located in the strength detection control box 1 and is connected to the movable detection column 11.

[0068] See also Figure 1-Figure 14 , further comprising: a pressure detection display 2 and a stretch detection display 3, wherein the pressure detection display 2 and the stretch detection display 3 are both fixedly mounted on the strength detection control box 1 and electrically connected to the clamping adjustment component;

[0069] And an inspection cover 9, wherein the inspection cover 9 is detachably connected to the strength detection control box 1.

[0070] The stretching push plate 12 is provided with a buffer head 13, and the buffer head 13 is detachably connected to the driving telescopic baffle 20 fixedly installed on the clamping adjustment assembly;

[0071] The pushing and mounting head 10 is provided with a pressing head detachably mounted thereon.

[0072] When performing strength testing on automobile parts, first, the clamping adjustment component can be started according to the type of automobile parts to be tested, so as to change the height of the automobile parts to be tested for subsequent testing operations. Then, the automobile parts to be tested are fixed on the clamping position of the clamping adjustment component (a part of the automobile parts with lower extrusion force or tensile force requirements), and the detection drive component is started. At this time, the mobile detection column 11 has three working states according to the type of automobile parts to be tested. In the first working state, the mobile detection column 11 pushes the pushing installation head 10 to move only upward, and pushes the automobile parts to be tested to achieve the purpose of pressure testing. Among them, pushing heads of different structures or shapes can be installed on the pushing installation head 10 to achieve the purpose of accurate testing according to the type of automobile parts. In the second working state, the mobile detection column 11 can push the tensile pushing plate 12 to move horizontally, and drive the buffer head 13 to move synchronously. When the buffer head 13 and the driving telescopic baffle fixedly installed on the clamping adjustment component 20 contacts, the telescopic baffle 20 is driven to change the distance between the clamping and adjusting components to achieve the purpose of stretching detection of automobile parts. In the third working state, after the mobile detection column 11 drives the stretching push plate 12 and the buffer head 13 to move horizontally for stretching detection, and the automobile parts are in a stretched state, the mobile detection column 11 drives the pushing installation head 10 and the pressure head to move upward to perform pressure detection on the automobile parts, thereby realizing the detection of automobile parts under more complex use conditions, and the detection data are transmitted to the pressure detection display 2 and the stretching detection display 3 respectively through the multiple sensors arranged on the clamping and adjusting components for reference by relevant staff. The operation is simple, and the automobile parts can be fully detected according to different detection requirements of different parts or the same parts, so as to ensure the accuracy of the detection results, and can meet the needs of various detection scenarios, improve the practicability and flexibility of the equipment, thereby improving the efficiency of the detection work, and providing convenience for the staff.

[0073] In one embodiment of the present invention, see Figure 1-Figure 14 , the clamping and adjusting assembly comprises:

[0074] A fixed base 5, wherein the fixed base 5 is fixedly mounted on the strength detection control box 1;

[0075] A limit rail 7, wherein the limit rail 7 is fixedly mounted on the strength detection control box 1, and a movable base 6 is also slidably mounted on the limit rail 7, wherein the fixed base 5 and the movable base 6 are respectively located on both sides of the movable detection column 11;

[0076] And a clamping adjustment unit, the number of the clamping adjustment unit is two sets, and the two sets of the clamping adjustment units are respectively located on the fixed base 5 and the movable base 6.

[0077] The clamping adjustment unit located on the mobile base 6 includes:

[0078] A U-shaped frame 14, the U-shaped frame 14 is fixedly mounted on the mobile base 6, and an adjustable telescopic cylinder 15 is also fixedly mounted on the U-shaped frame 14; another U-shaped frame 14 is fixedly mounted on the fixed base 5;

[0079] A guide slide bar 19, the two ends of which are fixedly connected to the movable base 6 and the U-shaped frame 14 respectively;

[0080] And a clamping detection module, the detection module is connected to the adjusting telescopic cylinder 15 and the guide slide rod 19 respectively.

[0081] The clamping detection module comprises:

[0082] A lifting slide plate 18, wherein the lifting slide plate 18 is sleeved on the guide slide bar 19 and is slidably connected to the guide slide bar 19;

[0083] A clamping device 17, wherein the clamping device 17 is fixedly mounted on the lifting slide 18, wherein an automobile component to be inspected is detachably mounted between two of the clamping devices 17;

[0084] and a detector 16 , wherein the detector 16 is fixedly connected to the clamping device 17 .

[0085] When clamping and fixing the automobile parts to be inspected, first, according to the type of automobile parts to be inspected, the adjusting telescopic cylinder 15 can be started, and the clamping device 17 and the lifting slide 18 can be pushed or pulled to slide on the guide slide bar 19 to adjust the height of the clamping device 17, so as to ensure that the inspection equipment can smoothly inspect the automobile parts. Among them, the clamping device 17 can adopt the existing clamping technology, such as hydraulic clamping or pneumatic clamping equipment, which will not be described in detail here. In addition, under the driving action of the adjusting telescopic cylinder 15, it is also convenient to load the automobile parts and the pressure head and other parts. Parts replacement work, and when the detection work is carried out, the pressure head can smoothly push the automobile parts, or the buffer head 13 can smoothly contact the driving telescopic baffle 20 fixedly installed on the mobile base 6 for tensile testing (when the first working state is detected, the buffer head 13 is located below the driving telescopic baffle 20 and does not contact the driving telescopic baffle 20), and through the buffer head 13, after the tensile force exceeds a certain limit, the buffer head 13 will extend into the interior of the tensile push plate 12 to avoid damage to equipment parts due to rigid contact, which will not be described in detail here;

[0086] In addition, since the movable base 6 can slide on the limiting guide rail 7, wherein a limiting structure is provided on the limiting guide rail 7, so that the fixed base 5 and the movable base 6 remain stable at a minimum distance, and when the pressure head pushes the lower surface of the automobile part, the movable base 6 will not continue to approach the fixed base 5 or deviate a short distance, or even cause the movable base 6 to separate from the limiting guide rail 7, thereby affecting the accuracy of the pressure detection, and when performing a tensile test, under the pushing action of the buffer head 13 on the driving telescopic baffle 20, the movable base 6 can move in a direction away from the fixed base 5 or have a tendency to move, so that the automobile part located between the fixed base 5 and the movable base 6 (i.e., above the detection active port 4) can be subjected to a tensile test. During the detection process, the detectors 16 on the two clamping devices 17 can transmit the detected data to the pressure detection display 2 and the tensile detection display 3 respectively. In addition, an adjustment handle 8 is also fixedly installed on the movable base 6, which can be pushed to the starting position by the staff after the detection to carry out the detection of the next part, which will not be elaborated here.

[0087] In one embodiment of the present invention, see Figure 1-Figure 14 , the detection drive component includes:

[0088] A support partition 21, wherein the support partition 21 is fixedly installed in the strength detection control box 1, wherein the number of the support partitions 21 is two, the two support partitions 21 and the strength detection control box 1 enclose a square space, and a limit slide 24 is also fixedly installed on the support partition 21;

[0089] A translation driving block 25, the translation driving block 25 is located in the supporting partition 21 and is slidably connected to the limiting slide 24;

[0090] A pressure frame 26, wherein the pressure frame 26 penetrates the translation driving block 25 and is slidably connected to the translation driving block 25, and the pressure frame 26 is also fixedly connected to the moving detection column 11;

[0091] And a stretching movable unit and a pushing movable unit, the stretching movable unit is respectively connected to the strength detection control box 1, the supporting partition 21 and the translation driving block 25, and the pushing movable unit is respectively connected to the supporting partition 21, the pressure frame 26 and the stretching movable unit.

[0092] The stretching moving unit comprises:

[0093] A reset member 23, two ends of which are respectively connected to the strength detection control box 1 and the translation drive block 25;

[0094] A driving member 22, wherein the driving member 22 is fixedly mounted on the supporting baffle 21, and a rotating shaft 27 is fixedly mounted on the output end of the driving member 22, and the rotating shaft 27 is rotatably connected to the supporting baffle 21;

[0095] A sector-shaped driving wheel 28, wherein the sector-shaped driving wheel 28 is fixedly mounted on the rotating shaft 27;

[0096] And a transmission roller 30, the transmission roller 30 is rotatably mounted on the translation driving block 25, and the transmission roller 30 is also rollingly connected with the fan-shaped driving wheel 28.

[0097] After the automobile parts to be inspected are fixed, the driving member 22 is started. The driving member 22 can be driven by hydraulic means, and the hydraulic device drives the rack to drive the gear. No further details are given here. Of course, for some inspection parts with low requirements, a motor can also be used. No further details are given here. Under the driving action of the driving member 22, the rotating shaft 27 can be rotated on the supporting partition 21, and the rotating shaft 27 can drive the fan-shaped driving wheel 28 to rotate (such as Fig. 9 As shown in the figure, the positions of various components are the initial positions of the detection). During the rotation of the sector-shaped driving wheel 28, the transmission roller 30 can be pushed to rotate on the translation driving block 25, and under the pushing action of the convex part of the sector-shaped driving wheel 28, the translation driving block 25 can also be moved to the left direction on the supporting partition 21 through the limiting slide 24, so that the mobile detection column 11 can drive the stretching pushing plate 12 and the buffer head 13 to move synchronously, so that the buffer head 13 contacts the driving telescopic baffle 20, and pushes the mobile base 6 to move to the left or move, so as to realize the stretching detection of automobile parts or the stretching detection in the pushing state (that is, the second and third working states). After the detection is completed, as the rotating shaft 27 and the fan-shaped driving wheel 28 return to their original positions, the translation driving block 25, the moving detection column 11 and the stretching push plate 12 are also restored to their original positions under the driving action of the reset member 23, wherein the reset member 23 can be in the form of a spring, and a tension sensor is arranged on the spring, so that when the fan-shaped driving wheel 28 pushes the translation driving block 25 to move and the automobile parts are stretched, the detection value of the detector 16 is removed by the tension value of the reset member 23, and then comprehensively processed and transmitted to the stretching detection display 3 to achieve the accuracy of the detection result. The reset member 23 can also adopt other existing pullback technologies, which will not be elaborated here.

[0098] In one embodiment of the present invention, see Figure 1-Figure 14 , the pushing moving unit comprises:

[0099] A limiting guide bar 33, wherein the limiting guide bar 33 is fixedly mounted on the rotating shaft 27;

[0100] The second sector-shaped driving wheel 29 is sleeved on the limiting guide bar 33 and is slidably connected to the limiting guide bar 33, and the second sector-shaped driving wheel 29 is also rollingly connected to the pressure frame 26;

[0101] And a clutch control module, the clutch control module is connected to the support partition 21, the fan-shaped driving wheel 29 and the limiting guide bar 33 respectively.

[0102] The clutch control module comprises:

[0103] A rotation control box 31, wherein the rotation control box 31 is fixedly connected to the limit guide bar 33 and is rotationally connected to the support partition 21;

[0104] A magnetic control rod 32, wherein the magnetic control rod 32 is inserted into the rotation control box 31 and is slidably connected to the rotation control box 31;

[0105] The connection control part 34 is fixedly mounted on the second sector driving wheel 29, and the connection control part 34 is also detachably connected to the magnetic control rod 32; the connection control part 34 can be in the form of a magnet plate;

[0106] and a telescopic rod 35 , wherein the telescopic rod 35 is fixedly connected to the supporting baffle 21 , and an output end of the telescopic rod 35 is detachably connected to the magnetic control rod 32 .

[0107] During the rotation of the rotating shaft 27, when the first working state is performed, the driving telescopic baffle 20 can be retracted. Then, during the movement of the translation driving block 25 pushed by the sector driving wheel 1 28 via the transmission roller 30, the stretching push plate 12 and the buffer head 13 on the mobile detection column 11 cannot contact the driving telescopic baffle 20 (at this time, the stretching push plate 12 and the buffer head 13 are located below the driving telescopic baffle 20), so that the stretching test can be omitted. As the rotating shaft 27 continues to rotate, when the convex portion of the sector driving wheel 2 29 gradually contacts the bottom wall of the pressure frame 26, the pressure frame 26 can be pushed to slide upward on the translation driving block 25, and finally the mobile detection column 11 and the pressure head can be driven to move upward, so that pressure detection of automobile parts can be performed. Similarly, when performing the second working state, at this time, under the pushing action of the fan-shaped driving wheel 1 28 (the fan-shaped driving wheel 2 29 has not yet pushed the pressure frame 26 to move upward), wherein the fan-shaped driving wheel 1 28 has the same structure as the fan-shaped driving wheel 2 29, and the size of the fan-shaped driving wheel 1 28 is larger than the size of the fan-shaped driving wheel 2 29, and the convex parts of the fan-shaped driving wheel 1 28 and the fan-shaped driving wheel 2 29 are both arc structures with equal diameters, then in the process of the arc-shaped convex part of the fan-shaped driving wheel 1 28 contacting with the transmission roller 30, the translation driving block 25 moves to the maximum distance, and the translation driving block 25 is in a stationary state, at this time, the stretching test in the second working state can be completed, and when the detection work needs to be ended directly, before the detection work is carried out (that is, as Fig. 9The magnetic direction of the magnetic control rod 32 can be changed by changing the current of the rotating control box 31, wherein the magnetic control rod 32 can adopt a rod-shaped structure of an electromagnet. After the magnetic direction of the magnetic control rod 32 changes, the magnetic repulsion between one end of the magnetic control rod 32 and the connecting control part 34 is changed into a magnetic attraction, so that the magnetic control rod 32 and the connecting control part 34 are attracted to each other. At the same time, the magnetic repulsion between the other end of the magnetic control rod 32 and the telescopic rod 35 is changed into a magnetic attraction. Then, under the pulling action of the telescopic rod 35, the fan-shaped driving wheel 29 can slide on the limiting guide strip 33 and be completely separated from the pressure frame 26. Then, during the whole process, that is, during the rotation of the rotating shaft 27, the fan-shaped driving wheel 29 cannot contact the pressure frame 26, and the movable detection column 11 and the pressure head cannot be moved upward for pressure detection. The measuring action is performed, and after the stretching test is completed, each part can be restored to its original position, which is beneficial to improving the flexibility of the equipment and can be applied to more detection scenarios. Of course, if the rotating shaft 27 is in a form that can be reversed, the rotating control box 31, the magnetic control rod 32 and the limiting guide bar 33 and other structures can also be omitted, so that the fan-shaped driving wheel 29 is directly fixed on the rotating shaft 27. After the stretching test is completed, the rotating shaft 27 is directly driven to reverse, so that each component can be restored to its original position. When the third working state is performed, the translation drive block 25 directly drives the moving detection column 11 and the stretching push plate 12 to move for stretching. As the rotating shaft 27 continues to rotate, the arc-shaped convex portion of the fan-shaped driving wheel 29 will contact the pressure frame 26, and push the moving detection column 11 and the pressure head to move upward for pressure detection. No more details will be given here.
