Description

Technical Field

[0001] The present invention relates to the technical field of component detection, and in particular to an automatic tensile and compressive detection device for component production. Background Art

[0002] In the process of parts production, ensuring product quality is crucial, especially in the fields of high strength or high precision requirements. Parts will be subjected to external tension or pressure during use, so tensile and compressive testing devices are required. Tensile and compressive tests can verify their bearing capacity under extreme conditions and prevent safety accidents caused by structural failure. Existing tensile and compressive testing devices still have some shortcomings.

[0003] For example, the invention patent with publication number CN111982659A discloses a multifunctional detection device for automobile parts, including a device body, the device body includes a front plate, a rear plate and a vertical plate, the vertical plate is arranged on the upper surface of the front plate, and the lower surface of the vertical plate is fixedly connected to the right end of the upper surface of the front plate, the middle part of the upper surface of the front plate is provided with an extrusion device, the middle part of the rear end of the upper surface of the front plate is provided with a rectangular groove, and an electric device is provided in the rectangular groove. The rotation of the screw rod causes the movable block to move backward, and the movement of the movable block drives the two movable blocks to continuously move away from each other, and continuously stretches the detection piece to achieve the effect of detecting the tensile strength. Compared with the manual stretching detection method, the stretching force is greater and the detectable range is wider. The stretching device and the extrusion device are arranged in the same device, which saves space compared with the independent arrangement of the extrusion and stretching detection devices.

[0004] Although the above-mentioned device can achieve the function of saving space, it cannot adapt to the use of parts with different structures when in use. It cannot adjust the contact surface of the clamping structure during tensile and compressive testing, and its adaptability is insufficient. In addition, the existing tensile and compressive testing devices cannot simulate the actual use environment during tensile and compressive testing. After the existing device clamps the two ends of the component, it cannot pull the component laterally to achieve tensile testing while causing the clamping structures on both sides to twist slightly.

[0017] The working principle and beneficial effects of the present invention are:

[0018] 1. By setting up a clamping assembly, multiple filling rods evenly distributed on the clamping assembly are used to press against the outer surface of the component, so that the device can fit the contour of the outer surface of components with different structures for clamping and fixing, thereby enhancing the adaptability of the device. The device can add filling liquid into the inner groove, and by extending or shortening the electric push rod, the push plate pushes the filling liquid forward. The filling liquid will push multiple filling rods against the contour of the component, thereby realizing the function of adapting to clamping with different contours.

[0019] 2. The device is provided with a traction steel rope, a through hole and a rubber sealing block. When a plane clamp is required, the bolts can be removed so that the rubber sealing block no longer blocks the through hole. At this time, the filling rod can be completely retracted into the interior of the device, so that the device can use the plane of the connecting shell to clamp and fix the components of the plane structure, thereby enhancing the adaptability of the device.

[0020] 3. By setting the guide block, the lap rod, the outer shell and the second spring, when the device performs the tensile test, the rotating block first abuts against the wavy surface of the guide block, so that the support seat can move back and forth while sliding, and then when the clamping force gradually increases and the tensile test is performed, the parts under test are twisted slightly, thereby simulating the actual use environment, solving the problem that the existing testing device cannot simulate the actual use environment during tensile and compressive tests.

[0021] 4. By setting up the motor, spline rod, first screw, fixed seat, second screw and slide seat, the device is more stable when clamped. When the motor drives the spline rod to rotate, it will drive the first screw to rotate into the fixed seat. At the same time, the rotation of the second screw will drive the slide seat to move. And for every rotation of the first screw and the second screw, the distance moved by the slide seat is the difference between the pitch of the first screw and the second screw, thereby realizing the fine-tuning function and ensuring the stability of the device during testing.

DETAILED DESCRIPTION

[0034] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Example 1

[0036] like Figure 1-Figure 10As shown, this embodiment proposes an automatic tensile and compressive testing device for parts production, including a base 1, a slide bar 4 is slidably installed on the base 1, a slide plate 2 is fixedly connected above the slide bar 4, a support seat 3 is slidably installed on the slide plate 2, a connecting plate 5 is fixedly connected to the slide bar 4, a compression detection component 6 is installed on the connecting plate 5, a first hydraulic rod 7 is installed on the compression detection component 6, a pressure block 8 is connected below the first hydraulic rod 7, a guide block 9 is fixedly arranged on the base 1, a second hydraulic rod 10 is installed in the support seat 3, a fixed block 11 is fixedly connected to the second hydraulic rod 10, a rotating block 12 is arranged on the fixed block 11, a lap rod 13 is fixedly connected to the support seat 3, a shell 14 is fitted on the outer side of the lap rod 13, the shell 14 and the slide plate 2 are fixedly connected, and a second spring 15 is installed between the shell 14 and the lap rod 13. Figure 5 It can be seen that the second spring 15 can reset the housing 14 and the lap rod 13 after relative displacement occurs between the housing 14 and the lap rod 13. Telescopic assemblies 16 are provided on both sides of the base 1. A motor 17 is installed on the support seat 3. A spline rod 18 is fixedly connected to the output shaft of the motor 17. The outer key of the spline rod 18 is connected to the first screw 19. The outer thread of the first screw 19 is threadedly installed with a fixed seat 20. The fixed seat 20 and the support seat 3 are fixedly connected. The first screw 19 is fixedly connected to the second screw 21. The outer thread of the second screw 21 is threadedly connected to a slide seat 22. The support seat 3 is fixedly connected to a guide rail 23. The slide seat 22 is slidably installed on the outer side of the guide rail 23. The spline rod 18 is driven to rotate by the motor 17. When the spline rod 18 rotates, the first The screw 19 is screwed into the interior of the fixed seat 20. At the same time, when the second screw 21 rotates, the slide 22 will slide on the device, and the distance moved by the slide 22 is equal to the difference between the pitches of the first screw 19 and the second screw 21, thereby realizing the fine-tuning function, so that the tensile and compressive testing work can be performed while the subsequent slow clamping is performed. Mounting blocks 24 are fixedly provided on both sides of the slide 22, and a clamping assembly 25 is installed on the mounting block 24. The fine-tuning function on the device cooperates with the clamping assembly 25, so that the device can stably clamp parts of different structures. A third hydraulic rod 26 is installed between two adjacent slides 2. The third hydraulic rod 26 can act on the telescopic assembly 16 when extending or shortening, so that the distance between the two slides 2 can be adjusted, thereby realizing the tensile and compressive testing functions.

[0037] Example 2

[0038] like Figure 1-Figure 10 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment also proposes an automatic tensile and compressive testing device for parts production.

[0039] In this embodiment, the slide plate 2, the slide rod 4 and the connecting plate 5 are fixedly connected to form an integral structure. The slide rod 4 ensures that the slide plate 2 can move straight. The slide rods 4 are evenly spaced on the slide plate 2. The slide plate 2 and the support seat 3 are symmetrically distributed on both sides of the third hydraulic rod 26. The slide plate 2 and the support seat 3 are used to pull or squeeze the parts to be tested, so as to perform tensile and compressive testing.

[0040] In this embodiment, the compression detection component 6 includes a fixed frame 601 fixedly connected to the base 1, a first connecting block 602 is fixedly arranged on the fixed frame 601, a second connecting block 603 is fixedly arranged on the base 1, a first connecting rod 604 is rotatably installed on the second connecting block 603, the first connecting rod 604 and the first connecting block 602 are slidably connected, a third connecting block 605 is rotatably installed on the first connecting rod 604, a fourth connecting block 606 is fixedly arranged on the third connecting block 605, a second connecting rod 607 is penetrated in the fourth connecting block 606, a nut 608 is threadedly installed on the outer side of the second connecting rod 607, a first spring 609 is installed between the nut 608 and the fourth connecting block 606, and the third connecting rod 607 is threadedly installed on the outer side of the second connecting rod 607. The second connecting rod 607 is fixedly connected to the first hydraulic rod 7, and the nut 608 is used to adjust the initial position of the top of the second connecting rod 607 to adapt to the use of parts of different heights. When the clamping force is gradually increased, the two ends of the part to be detected are pulled. At this time, the two adjacent second connecting blocks 603 move away from each other, and the first connecting rod 604 slides on the first connecting block 602, and the angle of the first connecting rod 604 also changes. The third connecting block 605 and the fourth connecting block 606 move downward, so that the second connecting rod 607 and the first hydraulic rod 7 press down the part to be detected, thereby realizing the function of synchronous tensile and compressive detection of parts, and the detection force can be adjusted by extending or shortening the first hydraulic rod 7.

[0041] In this embodiment, the upper and lower sides of the first spring 609 are abutted against the fourth connecting block 606, and the central axes of the second connecting rod 607, the first hydraulic rod 7 and the pressure block 8 are all collinear, so that the device can stably perform pressure resistance testing. The second connecting rod 607 and the fourth connecting block 606 are slidably connected, and the first spring 609 can gradually increase the pressure during pressure resistance testing, thereby improving the detection effect of the device.

[0042] In this embodiment, the rotating block 12 is rotatably installed on the fixed block 11. The rotating block 12 is a spherical structure. The center of the rotating block 12 is located inside the fixed block 11, ensuring that the rotating block 12 can rotate without falling off from the fixed block 11. The side of the guide block 9 close to the rotating block 12 is wavy. The rotating block 12 is suitable for driving the support seat 3 to slide back and forth when it abuts against the guide block 9 and moves along the length direction of the guide block 9. When the rotating block 12 abuts against the guide block 9, as the support seat 3 slides, the rotating block 12 can abut against the wavy surface of the guide block 9, thereby causing the support seat 3 to slide back and forth, so that the device can simulate the vibration in actual use to perform tensile testing, and the device can adjust the initial positions of the fixed block 11 and the rotating block 12 to change the amplitude of the simulated vibration.

[0043] In this embodiment, the telescopic component 16 includes a movable block 1601 slidably installed on both sides of the base 1, and a first rotating plate 1602 is rotatably installed on the movable block 1601 and one side of the skateboard 2, and a second rotating plate 1603 is rotatably installed on the first rotating plate 1602 and the other side of the skateboard 2. The two adjacent skateboards 2 are suitable for moving away from each other when the angle between the first rotating plate 1602 and the second rotating plate 1603 increases or moving closer to each other when the angle decreases. When the distance between the two adjacent skateboards 2 increases, the movable block 1601 between the first rotating plate 1602 and the second rotating plate 1603 can ensure that the distances of the skateboards 2 moving in the opposite directions are the same, thereby avoiding the situation where the moving distances of the skateboards 2 on both sides of the device are inconsistent.

[0044] In this embodiment, the pitch of the first screw 19 is greater than the pitch of the second screw 21, and the thread direction of the first screw 19 and the second screw 21 is the same. The first screw 19 is suitable for being screwed into the interior of the fixed seat 20 when the spline rod 18 rotates. While the first screw 19 is screwed into the interior of the fixed seat 20, the second screw 21 continues to rotate, so as to realize the fine-tuning function during subsequent clamping and ensure the stability of the clamped parts.

[0045] In this embodiment, the clamping assembly 25 includes a connecting shell 2501 fixedly connected to the mounting block 24, a filling rod 2502 is slidably installed in the connecting shell 2501, an inner groove 2504 is provided in the mounting block 24 and the connecting shell 2501, an electric push rod 2505 is installed in the mounting block 24, a push plate 2506 is fixedly connected to the electric push rod 2505, and a sealing ring 2507 is fixedly connected to the outer side of the push plate 2506. When the two groups of mounting blocks 24 on the device are close to each other, the filling rod 2502 in the connecting shell 2501 can abut against the contact surface of the parts. When the electric push rod 2505 is extended, the push plate 2506 and the sealing ring 2507 move and support multiple filling rods 2502, thereby adapting to the clamping and fixation of parts with different contours.

[0046] In this embodiment, the filling rods 2502 are evenly distributed in the connecting shell 2501, and a traction steel rope 2503 is fixedly connected between the filling rods 2502 and the connecting shell 2501. The traction steel rope 2503 prevents the filling rods 2502 from completely detaching from the device, and the filling rods 2502 can be distributed at various positions of the components for clamping.

[0047] In this embodiment, a through hole 2510 is provided on the mounting block 24, and the through hole 2510 and the inner groove 2504 are interconnected. A bolt 2508 is installed on the inner thread of the through hole 2510, and a rubber sealing block 2509 is fixedly provided below the bolt 2508. Filling liquid can be added to the inner groove 2504 through the through hole 2510, and the components can be stably clamped through pressure transmission. Subsequently, the rubber sealing block 2509 can be used to block the through hole 2510 by installing the bolt 2508 to prevent the filling liquid from flowing out to the outside of the device.

[0048] Specifically, the present invention is an automatic tensile and compressive testing device for parts production. First, Figure 1-Figure 6 As shown, the base 1 and the fixing frame 601 are used to support the device as a whole. The spline rod 18 is driven to rotate by the motor 17. When the spline rod 18 rotates, the first screw 19 is screwed into the interior of the fixing seat 20. The first screw 19 rotates and slides on the outside of the spline rod 18. At the same time, when the second screw 21 rotates, the slide 22 is slid on the device. Since the first screw 19 and the second screw 21 have the same thread rotation direction, the direction in which the slide 22 is moved by the second screw 21 is opposite to the direction in which the slide 22 is pushed by the first screw 19 to move. When the first screw 19 rotates a single circle, the distance moved by the slide 22 is equal to the difference between the pitches of the first screw 19 and the second screw 21, thereby realizing the fine-tuning function. When the slide 22 moves, it drives the mounting block 24 and the clamping assembly 25 to slide. Figure 7 and Figure 8 As shown, filling liquid is added to the inner groove 2504 through the through hole 2510. After the filling liquid is added, the rubber sealing block 2509 is blocked by the mounting bolt 2508. Even if the pressure in the inner groove 2504 increases, the rubber sealing block 2509 will not be pushed out. The fine-tuning function on the device cooperates with the clamping assembly 25, so that the two groups of mounting blocks 24 slowly approach each other, and the multiple filling rods 2502 evenly distributed in the connecting shell 2501 abut against the contact surface of the parts. When the electric push rod 2505 is extended, the filling liquid in the inner groove 2504 can push the plate 2506 and the sealing ring 2507 to move and support the multiple filling rods 2502 after the pressure increases, so that the multiple filling rods 2502 can be clamped and fixed to adapt to the parts with different contours. Compared with the conventional method of cooperating with the filling rod 2502 through an elastic member, the present invention uses the filling liquid pressurization method, which has the advantage of keeping the pressure of each filling rod 2502 uniform.

[0049] like Figure 1-Figure 5 , Fig. 9 and Fig.10 As shown, the third hydraulic rod 26 can increase or decrease the distance between two adjacent slide plates 2 when extending or shortening, the slide plate 2 and the connecting plate 5 slide on the base 1 through the sliding rod 4 and act on the telescopic assembly 16, the angle between the first rotating plate 1602 and the second rotating plate 1603 rotatably mounted on the movable block 1601 increases, and the movable block 1601 moves straight on the base 1, thereby realizing the tensile detection function, and when the connecting plate 5 slides outward, it pulls the first connecting rod 604 through the second connecting block 603, Figure 3 The first connecting rod 604 rotates counterclockwise and slides on the first connecting block 602, so that the third connecting block 605 and the fourth connecting block 606 at the top of the first connecting rod 604 move downward, so that the device can slowly clamp the parts while using the telescopic assembly 16 to perform a tensile test and using the pressure block 8 under the first hydraulic rod 7 to perform a compressive test. The nut 608 is used to adjust the initial position of the top of the second connecting rod 607 to adapt to the use of parts of different heights. The first spring 609 can gradually increase the pressure as the fourth connecting block 606 moves downward during the compressive test, so as to perform a compressive performance test. Figure 4 and Figure 5 As shown, when the support seat 3 slides, the rotating block 12 can abut against the wavy surface of the guide block 9. Figure 5 It can be seen that the second spring 15 can reset the shell 14 and the lap rod 13 after the relative displacement of the shell 14 and the lap rod 13, so that the support seat 3 can achieve a small reciprocating sliding in the direction perpendicular to the tension during the tensile test of the parts, so that the device can simulate the vibration environment under actual use conditions to perform tensile testing, and the second hydraulic rod 10 can adjust the initial positions of the fixed block 11 and the rotating block 12, thereby changing the position where the rotating block 12 abuts against the guide block 9, and then changing the amplitude of the simulated vibration.

[0050] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
