Description

Technical Field

[0001] The present invention relates to the field of new energy vehicles, and in particular to a rigidity detection device for new energy vehicle parts. Background Art

[0002] New energy vehicles refer to vehicles that use unconventional automotive fuels as their power source and integrate advanced technologies in vehicle power control and drive to form vehicles with advanced technical principles, new technologies, and new structures. During the production process of new energy vehicles, their parts need to be tested after production is completed. Traditional inspection tools for new energy vehicle parts include inspection plates and rigidity testers. The new energy vehicle parts are placed on the inspection plates and inspected by rigidity testers. However, when the inspection tools abut against the surface of the parts during rigidity testing, the parts are prone to side sliding and other displacements, resulting in measurement errors.

[0003] There is a rigidity detection device, which includes a lifting frame and a rigidity detector. A positioning clamping platform is arranged below the rigidity detector. The positioning clamping platform clamps the components from both sides to position and fix them. Then the rigidity detector moves down, contacts and squeezes the components with static pressure contacts, and measures the deformation degree of the components through displacement sensors to fully reflect the pressure bearing capacity of the components and achieve the purpose of measurement.

[0004] However, this rigidity detection device clamps the components from both sides and has no supporting structure at the bottom. The rigidity detector squeezes the components from top to bottom. If the clamping is too loose, the components are easily displaced and affect the detection. If the clamping is too tight, the components are easily deformed and affect the strength. At the same time, there are many types of new energy vehicle components, most of which are irregular in shape and differ greatly from each other. The clamping structure of this device can only clamp from both sides, which has great limitations and cannot be applied to the clamping detection of various irregular components. Summary of the invention

[0005] In order to overcome the deficiencies of the prior art, the purpose of the present invention is to provide a new energy vehicle component rigidity detection device to solve the problem that the clamping structure of the existing detection device is greatly limited and cannot be applied to the clamping inspection of various irregular components.

[0006] To achieve the above-mentioned purpose, the present invention provides a new energy vehicle parts rigidity detection device, including a lifting frame and a rigidity detector, the lifting frame is used to drive the rigidity detector to move up and down, and also includes a support seat fixed on the side of the lifting frame, the support seat is provided with a liquid storage cavity, a plurality of support cylinders are arranged and fixed in the support seat, a piston rod that can slide up and down is provided in the support cylinder, the piston rod extends upward, a connecting pipe is connected to the bottom of the support cylinder, and the other end of the connecting pipe is connected to the liquid storage cavity; a closing component is provided between the connecting pipe and the liquid storage cavity, and the closing component is used to close the connecting pipe, and the support cylinder, the connecting pipe and the liquid storage cavity are filled with hydraulic oil.

[0007] The principle of the technical solution is as follows: the lifting frame is used to drive the rigidity detector to move up and down, and moves downward after the parts are fixed, so that the static pressure contact of the rigidity detector squeezes the parts for detection; the support seat is used to install a plurality of the support cylinders, and the support cylinder is provided with the piston rod, and the upper end of the piston rod is fixed with a support block, and the lower end of the support cylinder is connected with the liquid storage chamber through the connecting pipe, and the support cylinder, the connecting pipe and the liquid storage chamber are filled with hydraulic oil. When performing the detection, the new energy vehicle parts are placed on the plurality of the support blocks, and the support blocks in contact with them are moved downward by gravity or by pressing the parts, and the piston rod moves downward to squeeze out the hydraulic oil in the support cylinder, and the squeezed hydraulic oil passes through the connecting pipe and the liquid storage chamber. The liquid storage chamber enters the supporting cylinder that is not in contact with the component, so that the corresponding piston and the supporting block are lifted. The lifted supporting block is located on the side of the component to limit its horizontal position; at this time, the closing component is started again to close the connecting pipe. After closing, the lifting frame is started to move the rigidity detector downward, so that the static pressure contact of the rigidity detector is in contact with the component, and pressure is gradually applied, and the deformation degree is measured by the displacement sensor to fully reflect the pressure bearing capacity of the component; at this time, since the hydraulic oil can no longer be discharged, the supporting block and the piston rod in contact with the component no longer move, and the component can be effectively supported to facilitate detection, and the supporting block extending upward can limit the component and fix it.

[0008] Compared with the prior art, the beneficial effects of the present invention are: 1. The support block can be flexibly moved up and down and changed accordingly according to the shape of the component, so that the component placement is more stable.

[0009] 2. This solution has support at the bottom, and can also clamp irregular parts, with many clamping points. Even without clamping too tightly, the accuracy of the parts position can be ensured.

[0010] 3. By using hydraulic oil, the support block that moves downward can better fit the shape of the component, and the discharged hydraulic oil moves to other support cylinders, which can move the other support blocks that are not in contact with the component upward, limit the component, avoid side slippage or displacement during squeezing, and enhance stability during detection.

[0011] As a preferred embodiment of the present invention, at least one limit assembly is arranged on the side of the support seat, and the limit assembly includes a mounting frame, a limit push rod and a push block. The mounting frame is fixed to the side of the support seat and is used to install the limit push rod. The push block is fixed on the piston of the limit push rod. The limit push rod is used to push the push block to the gap between two adjacent support blocks and press against the component to position it.

[0012] Beneficial effect: The mounting frame of the limit assembly is used to install the limit push rod, and the limit push rod is used to push the push block to the gap between two adjacent support blocks, and press against the component to position it. The limit push rod is used for auxiliary limiting. After extending, it presses against the component through the push block, and presses the other side of the component against the side of the support block extending upward, so as to further achieve the fixing effect and avoid small-scale displacement during detection.

[0013] As a preferred embodiment of the present invention, the push block is L-shaped and is inverted and fixed on the piston of the limit push rod.

[0014] Beneficial effect: the push block is fixed upside down on the piston of the limit push rod, that is, the lower end of the L-shape, i.e. the horizontal section, is fixed on the piston of the limit push rod. After the push block is extended, the side of the L-shaped horizontal section close to the corner can press against the component to achieve the limiting effect, and the side of the L-shaped vertical section close to the corner can press the component to prevent the component from moving up.

[0016] Beneficial effect: Each connecting pipe is provided with a solenoid valve. After the parts are placed, the connecting pipe is closed by controlling the solenoid valve, so that the piston rod and the support block can be quickly fixed.

[0017] As a preferred embodiment of the present invention, the sealing component is a blocking piston plate and a lifting mechanism, the blocking piston plate is slidably arranged in the liquid storage chamber, and the lifting mechanism is arranged below the blocking piston plate for lifting the blocking piston plate to block and close the lower end of the connecting pipe.

[0018] Beneficial effect: the lifting mechanism is used to lift the blocking piston plate to block and close the lower end of the connecting pipe, thereby achieving the effect of closing the connecting pipe. The blocking piston plate blocks and closes multiple connecting pipes uniformly, which is relatively low in cost.

[0019] As a preferred embodiment of the present invention, the lifting mechanism is an electric push rod, the electric push rod is fixed in the liquid storage cavity below the blocking piston plate, and the piston of the electric push rod is fixedly connected to the blocking piston plate.

[0020] Beneficial effect: After the electric push rod is extended, the blocking piston plate is pushed upward to achieve the purpose of blocking the connecting pipe.

[0021] As a preferred embodiment of the present invention, the lifting mechanism is composed of a gear, a rack, a rocker and a fixed part. The gear is rotatably arranged in the liquid storage chamber, the rack is fixedly connected to the blocking piston plate and meshes with the gear, the rocker is fixedly connected to the gear shaft and is arranged on the outside of the support seat; the fixed part is arranged on one side of the rocker for fixing the rocker, and a slide rail is arranged in the liquid storage chamber, and the slide rail is used to guide the rack.

[0022] Beneficial effect: The rocker is used to drive the gear to rotate, allowing the rack to move up and down, and then allowing the blocking piston plate to move up and down, thereby achieving the purpose of blocking the connecting pipe. By shaking the rocker manually, the cost can be further reduced; the slide rail is used to guide and limit the rack, and the fixing part is used to lock the rocker.

[0023] As a preferred embodiment of the present invention, the fixing member is a disk fixed on the outside of the support seat, the disk is provided with a plurality of fixing holes, a fixing rod is slidably provided in the rocker, and the fixing rod can be slidably inserted into the fixing hole to complete the fixation.

[0024] Beneficial effect: When the rocker arm is rotated, the fixing rod can be used to bear force and is easy to rotate. When the blocking piston plate is blocked, the fixing rod can be slid into the fixing hole to complete the fixation, thereby avoiding the blocking piston plate moving down during detection and causing erroneous detection results.

[0025] As a preferred embodiment of the present invention, a plurality of rubber plugs are provided on the blocking piston plate, and the plurality of rubber plugs correspond to the plurality of connecting tubes and are used to block and seal the connecting tubes.

[0026] Beneficial effect: After the rubber plug is inserted into the connecting pipe, it can effectively block the connecting pipe, avoiding the connecting pipe from being not completely closed due to the loose contact between the blocking piston plate and the connecting pipe, thereby causing the piston rod to move up and down during detection and affecting the detection result.

[0027] As a preferred embodiment of the present invention, a connecting seat is provided between the supporting seat and the lifting frame, and the connecting seat is used to connect the supporting seat and the lifting frame.

[0042] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0043] Embodiment 1 As attached Figure 1 ~Attached Figure 4As shown, the present invention provides a new energy vehicle component rigidity detection device: comprising a lifting frame 1 and a rigidity detector 2, the lifting frame 1 is used to drive the rigidity detector 2 to move up and down, a support seat 3 is fixed on the side of the lifting frame 1, a liquid storage chamber 4 is arranged in the support seat 3, a plurality of support cylinders 5 are arranged and fixed in the support seat 3, a piston rod 6 which can slide up and down is arranged in the support cylinder 5, the piston rod 6 extends upward, a connecting pipe 7 is connected to the bottom of the support cylinder 5, and the other end of the connecting pipe 7 is connected to the liquid storage chamber 4; the lifting frame 1 is used to drive the rigidity detector 2 to move up and down, and moves downward after the component is fixed, so that the static pressure contact of the rigidity detector 2 squeezes the component for detection, The support seat 3 is used to install multiple support cylinders 5, and the support cylinder 5 is provided with the piston rod 6. The upper end of the piston rod 6 is fixed with a support block. The lower end of the support cylinder 5 is connected with the liquid storage chamber 4 through the connecting pipe 7. The support cylinder 5, the connecting pipe 7 and the liquid storage chamber 4 are filled with hydraulic oil. When testing, the new energy vehicle parts are placed on the multiple support blocks, and the support blocks in contact with them are moved downward by gravity or pressing the parts. The piston rod 6 moves downward to squeeze out the hydraulic oil in the support cylinder 5. The squeezed hydraulic oil enters the support cylinder 5 that is not in contact with the parts through the connecting pipe 7 and the liquid storage chamber 4, so that the corresponding piston and the support block are lifted.

[0044] As attached Figure 3 As shown, in the present embodiment, a sealing component is provided between the connecting tube 7 and the liquid storage chamber 4, and the sealing component is used to seal the connecting tube 7. When the parts are placed, the sealing component is started. The sealing component adopts a solenoid valve 8, and the solenoid valve 8 is provided on each of the connecting tubes 7. The connecting tube 7 is closed by the solenoid valve 8 to stop the hydraulic oil from flowing, and then the lifting frame 1 is started to move the rigidity detector 2 downward, so that the static pressure contact of the rigidity detector 2 is in contact with the parts, and pressure is gradually applied, and then the deformation degree is measured by the displacement sensor to fully reflect the pressure bearing capacity of the parts; at this time, since the hydraulic oil can no longer be discharged, the support block and the piston rod 6 in contact with the parts no longer move, and the parts can be effectively supported to facilitate detection, and the support block extending upward can limit the parts and fix them.

[0045] As attached Figure 1 and attached Figure 2As shown, in the present embodiment, at least one limit assembly 12 is provided on the side of the support seat 3, and the limit assembly 12 includes a mounting frame 121, a limit push rod 122 and a push block 123. The mounting frame 121 is fixed to the side of the support seat 3 for installing the limit push rod 122, and the push block 123 is fixed on the piston of the limit push rod 122. The limit push rod 122 is used to push the push block 123 to the gap between two adjacent support blocks, and to press against the component to position it. Specifically: the limit push rod 122 is used for auxiliary limiting. After extending out, it presses against the component through the push block 123, and presses the other side of the component against the side of the support block extending upward, so as to further achieve the fixing effect and avoid small-range displacement during detection.

[0046] As attached Figure 1 and attached Figure 2 As shown, in the present embodiment, the push block 123 is L-shaped and is fixed inverted on the piston of the limiting push rod 122; that is, the lower end of the L-shape, i.e., the horizontal section, is fixed on the piston of the limiting push rod 122. After the push block 123 is extended, the side of the L-shaped horizontal section close to the corner can resist the component to achieve the limiting effect, while the side of the L-shaped vertical section close to the corner can press the component to prevent the component from moving up.

[0047] As attached Figure 1 As shown, in this embodiment, a connecting seat 13 is provided between the supporting seat 3 and the lifting frame 1, and the connecting seat 13 is used to connect the supporting seat 3 and the lifting frame 1, so that the connection between the two is tighter, thereby improving the stability of the entire device.

[0048] Embodiment 2 As attached Figure 5As shown: Different from the first embodiment, in this embodiment, the sealing component is a blocking piston plate 9 and a lifting mechanism 10, the blocking piston plate 9 is slidably arranged in the liquid storage chamber 4, and the lifting mechanism 10 is arranged below the blocking piston plate 9, and is used to lift the blocking piston plate 9 so that it blocks and closes the lower end of the connecting pipe 7; a plurality of rubber plugs 11 are arranged on the blocking piston plate 9, and the plurality of rubber plugs 11 correspond to the plurality of connecting pipes 7, and are used to block and close the connecting pipe 7. After the rubber plug 11 is extended into the connecting pipe 7, the connecting pipe 7 can be effectively blocked to prevent the blocking piston plate 9 from contacting the connecting pipe 7. The connecting pipe 7 is not completely closed due to laxity, which causes the piston rod 6 to move up and down during detection and affects the detection result; the lifting mechanism 10 adopts an electric push rod 101 or a hydraulic rod to lift the blocking piston plate 9 to block and close the lower end of the connecting pipe 7, thereby achieving the effect of closing the connecting pipe 7. The blocking piston plate 9 uniformly blocks and closes multiple connecting pipes 7. Compared with the multiple solenoid valves 8 in Example 1, the structure of the lifting mechanism 10 and the blocking piston plate 9 can effectively reduce costs, and at the same time omit the control, installation, and wiring of multiple solenoid valves 8, resulting in a simpler structure, fewer leakage points, and more practical.

[0049] In this embodiment, when the blocking piston plate 9 moves upward, part of the hydraulic oil will be squeezed into the connecting pipe 7. At this time, since the push block is L-shaped, it extends out and presses on the top of the component to limit the component. This prevents the piston rod 6 below the component from moving upward, so that the hydraulic oil can only enter the connecting pipe 7 where there is no component above, thereby preventing the component from moving again when the blocking piston plate 9 moves upward.

[0050] Embodiment 3 As attached Figures 6-8 As shown: Different from the second embodiment, in this embodiment, the lifting mechanism 10 is a gear 102, a rack 103, a rocker 104 and a fixing part. The gear 102 is rotatably arranged in the liquid storage chamber 4, the rack 103 is fixedly connected to the blocking piston plate 9 and meshes with the gear 102, the rocker 104 is fixedly connected to the gear shaft and is arranged on the outer side of the support seat 3; the fixing part is arranged on one side of the rocker 104 for fixing the rocker 104, and a slide rail 105 is arranged in the liquid storage chamber 4, and the slide rail 105 is used to guide the rack 103; the rocker 104 is used to drive the gear 102 to rotate, so that the rack 103 moves up and down, and then the blocking piston plate 9 moves up and down, so as to achieve the purpose of blocking the connecting pipe 7, and the cost can be further reduced by manually shaking the rocker 104; the slide rail 105 is used to guide and limit the rack 103.

[0051] As attached Figures 6-8 As shown, the fixing member can adopt a ratchet structure, a snap-fit ​​structure, etc. In the present embodiment, the fixing member is a disc 106 fixed on the outside of the support seat 3, and the disc 106 is provided with a plurality of fixing holes 107. A fixing rod 108 is slidably provided in the rocker 104, and the fixing rod 108 can be slidably inserted into the fixing hole 107 to complete the fixation. When the rocker 104 is rotated, the fixing rod 108 can be used to bear force and is convenient for rotation. When the blocking piston plate 9 is blocked, the fixing rod 108 is slidably inserted into the fixing hole 107 to complete the fixation, thereby avoiding the blocking piston plate 9 from moving downward during detection and causing an error in the detection result.
