Abstract
Description
Technical Field
[0001] The utility model belongs to the field of thrust detection, and specifically relates to an elastic thrust detection device. Background Art
[0002] The original device is a spring-driven thrust detection device. However, since it is difficult to keep the force exerted by the spring constant, when the spring is compressed, a greater force is required to continue compressing and deforming it. As a result, in the state where the spring is completely compressed, the external force applied far exceeds the specified detection force. Moreover, when the spring is completely compressed instantaneously, an uncontrollable impact force will be generated, causing the welded part to fail.
[0003] Therefore, there is this utility model. A cylinder is used as a substitute for the spring, and the compression force applied to the cylinder is constant through air pressure adjustment. That is to say, the compression force applied to the cylinder by the external force is constant, thus ensuring that the force value of the thrust detection is constant. Using the cylinder thrust detection does not need to be pushed to the end of the cylinder, and no impact force will be generated to cause the welded part to fail.
[0004] For this reason, the utility model provides an elastic thrust detection device. Content of the Utility Model
[0005] In order to make up for the deficiencies of the prior art and solve at least one technical problem proposed in the background art.
[0006] The technical solution adopted by the utility model to solve its technical problems is as follows: An elastic thrust detection device described in the utility model includes a cylinder; a trachea is fixedly connected to the middle of the cylinder; a first screw is fixedly connected to the top of the cylinder; a second screw is fixedly connected to the bottom of the cylinder; a first nut is threadedly connected to the side wall of the second screw; a piston rod is slidably connected inside the cylinder; a nylon head is fixedly connected to the bottom of the piston rod; a second nut is threadedly connected to the middle of the piston rod; the second nut contacts the bottom of the nylon head; effectively increasing the firmness of detecting the welded part with a constant thrust and not damaging the welded part body.
[0007] Preferably, a first rectangular plate is fixedly connected to the middle of the cylinder; the first rectangular plate is arranged near the bottom of the cylinder; a second rectangular plate is fixedly connected to the middle of the cylinder; the second rectangular plate is arranged near the top of the cylinder; four columns are fixedly connected between the first rectangular plate and the second rectangular plate; the four columns are symmetrically arranged; effectively reducing the situation that the device dropping causes damage to the cylinder, effectively extending the service life of the device, and enhancing the safety of the device.
[0008] Preferably, two fixing blocks are fixedly connected to the side wall of the second rectangular plate; the two fixing blocks are symmetrically arranged; a sliding plate is fixedly connected to the side wall of the fixing block; the end of the sliding plate is slidably connected to a supporting vertical plate; two sliding grooves are formed in the side wall of the supporting vertical plate; the two sliding grooves are symmetrically arranged; the sliding plate slides inside the sliding groove; effectively enhancing the stability and smoothness during the detection process of the thrust detection device, and reducing the situation that components fly out accidentally during the detection of the hand-held thrust device and cause serious injury to the hand.
[0009] Preferably, a placement plate is fixedly connected to the inner side wall of the supporting vertical plate; the placement plate is arranged near the bottom of the supporting vertical plate; which helps to maintain the stability of the welded part during the thrust detection process, thereby improving the accuracy of the detection.
[0010] Preferably, a scale is fixedly connected to the outer side wall of the supporting vertical plate; the scale is arranged near the sliding groove; which is convenient for subsequent data analysis and comparison, and enhances the accuracy of the device.
[0011] Preferably, a support column is fixedly connected to the bottom of the supporting vertical plate; the support column is made of metal; enhancing the stability of the entire structure, reducing the damage of components caused by the device tipping over, and at the same time improving the aesthetics of the device.
[0012] Preferably, a toolbox is fixedly connected to the outer side wall of the supporting vertical plate; the toolbox is arranged near the top of the sliding groove; making it easier for the operator to find the required tools, thereby reducing the search time, improving work efficiency, and at the same time increasing the aesthetics and practicality of the device.
[0013] The beneficial effects of the present utility model are as follows:
[0014] For the elastic thrust detection device of the present utility model, through the present utility model, the firmness of the welded part can be detected with a constant thrust without damaging the welded part itself. For example, if I need to detect the welded part with a thrust of 50 ± 5N, then adjust the air pressure to reach this thrust (the air pressure needs to be adjusted to 0.2 MPA during the subsequent verification process), and conduct the thrust detection. As long as the work of the cylinder is overcome and the cylinder is pushed forward by 10 mm, the generated thrust is 50 ± 5N.
[0015] For an existing spring-type component, since the spring itself generates an increasing deformation after being compressed, the required thrust becomes larger and larger, rather than a constant thrust. And at the moment when the spring is finally compressed to the bottom, an uncontrollable impact force will be generated to impact the welded part itself, resulting in damage to the strength of the welded part.

Detailed implementation manners
[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.
[0023] The following gives specific embodiments.
[0024] Such as Figure 1As shown in the figure, an elastic thrust detection device according to an embodiment of the present utility model includes a cylinder 1; a trachea 11 is fixedly connected to the middle of the cylinder 1; the trachea 11 is arranged near the top of the cylinder 1; a first screw 12 is fixedly connected to the top of the cylinder 1; a second screw 13 is fixedly connected to the bottom of the cylinder 1; a first nut 14 is threadedly connected to the middle of the second screw 13; a piston rod 15 is slidably connected to the inside of the cylinder 1; a nylon head 16 is fixedly connected to the bottom of the piston rod 15; a second nut 17 is threadedly connected to the middle of the piston rod 15; the second nut 17 contacts the bottom of the nylon head 16; during operation, the end of the trachea 11 is connected to a precision pressure regulating valve, and the nylon head 16 contacts the welded part. For example, if I need to detect the welded part with a thrust of 50±5N, then adjust the air pressure to reach this thrust (the air pressure needs to be adjusted to 0.2MPA during the subsequent verification process), and detect the welded part with this thrust. As long as the work done by the cylinder 1 is overcome and the cylinder 1 is pushed forward by a distance of 10mm, the generated thrust is 50±5N. This method effectively reduces the problems of inconsistent thrust and the failure of the welded part caused by impact force, effectively increases the firmness of detecting the welded part with a constant thrust, and does not damage the welded part body.
[0025] As Figure 2 and Figure 3 shown in the figure, a first rectangular plate 2 is fixedly connected to the middle of the cylinder 1; the first rectangular plate 2 is arranged near the bottom of the cylinder 1; a second rectangular plate 21 is fixedly connected to the middle of the cylinder 1; the second rectangular plate 21 is arranged near the top of the cylinder 1; four columns 22 are fixedly connected between the first rectangular plate 2 and the second rectangular plate 21; the four columns 22 are symmetrically arranged; during operation, when the thrust detection device accidentally falls, the first rectangular plate 2, the second rectangular plate 21 and the columns 22 form a protective frame, effectively reducing the damage to the cylinder 1 caused by the device falling, effectively extending the service life of the device, and enhancing the safety of the device.
[0026] As Figures 2 to 4 shown in the figure, two fixing blocks 3 are fixedly connected to the side wall of the second rectangular plate 21; the two fixing blocks 3 are symmetrically arranged; a sliding plate 31 is fixedly connected to the side wall of the fixing block 3; the end of the sliding plate 31 is slidably connected to a supporting vertical plate 32; two sliding grooves 33 are formed on the side wall of the supporting vertical plate 32; the two sliding grooves 33 are symmetrically arranged; the sliding plate 31 slides inside the sliding grooves 33; during operation, when detecting the thrust of the welded part, the thrust detection device is placed on the bracket, so that the nylon head 16 of the detection device contacts the welded part, and the supporting vertical plate 32 is pushed to slide inside the sliding grooves 33, and the cylinder 1 stops after being pushed to the required distance, effectively enhancing the stability and smoothness of the thrust detection device during the detection process, and reducing the serious injury to the hand caused by the accidental flying out of the components when holding the thrust device for detection.
[0027] As Figure 2 and Figure 4 shown, a storage plate 4 is fixedly connected to the inner side wall of the support vertical plate 32; the storage plate 4 is arranged at a position close to the bottom of the support vertical plate 32; during operation, the welded part is placed on the top of the storage plate 4 for thrust detection. The storage plate 4 provides a stable surface, which helps to maintain the stability of the welded part during the thrust detection, thereby improving the accuracy of the detection. By placing the welded part on the storage plate 4, it is possible to avoid the welded part directly contacting the hard object surface, reducing the damage to the welded part during the detection. Using the storage plate 4 effectively reduces the bending and reaching actions of the operator during the thrust detection, thereby reducing the safety risk caused by improper operation.
[0028] As Figure 2 and Figure 4 shown, a scale 5 is fixedly connected to the outer side wall of the support vertical plate 32; the scale 5 is arranged at a position close to the sliding groove 33; during operation, when performing thrust detection on the welded part, the cylinder 1 is pushed to an appropriate distance in combination with the scale 5, and the detection is carried out with this thrust. The magnitude of the thrust is directly read through the scale on the scale 5, providing relatively accurate measurement data for the operator. The scale on the scale 5 can also help record the measured thrust value, facilitating subsequent data analysis and comparison, and enhancing the accuracy of the device.
[0029] As Figure 2 and Figure 4 shown, a support column 6 is fixedly connected to the bottom of the support vertical plate 32; the support column 6 is made of metal material; during operation, the setting of the support column 6 can bear and disperse the pressure from above, enhancing the stability of the entire structure, reducing the situation of component damage caused by the device tipping over, and at the same time improving the aesthetics of the device.
[0030] As Figure 2 and Figure 4 shown, a toolbox 7 is fixedly connected to the outer side wall of the support vertical plate 32; the toolbox 7 is arranged at a position close to the top of the sliding groove 33; during operation, some commonly used tools and components are placed inside the toolbox 7. The toolbox 7 can effectively protect the tools from damage and rust, extending the service life of the tools; the setting of the toolbox 7 makes it easier for the operator to find the required tools, thereby reducing the search time, improving work efficiency, and at the same time increasing the aesthetics and practicality of the device.
[0031] During operation, the end of the air pipe 11 is connected to a precision pressure regulating valve, and the nylon head 16 contacts the welded part. For example, if I need a thrust of 50 ± 5 N to detect the welded part, then adjust the air pressure to reach this thrust (the air pressure needs to be adjusted to 0.2 MPA during the subsequent verification process), and use this thrust to detect the welded part. As long as the cylinder 1 does work and is pushed forward by 10 mm, the generated thrust is 50 ± 5 N. This method effectively increases the firmness of detecting the welded part with a constant thrust and does not damage the welded part itself. When the thrust detection device accidentally falls, the first rectangular plate 2, the second rectangular plate 21, and the column 22 form a protective frame, effectively reducing the damage to the cylinder 1 caused by the device falling, effectively extending the service life of the device, enhancing the safety of the device. When performing thrust detection on the welded part, the thrust detection device is placed on the bracket, so that the nylon head 16 of the detection device contacts the welded part, and the supporting vertical plate 32 is pushed to slide inside the chute 33. After the cylinder 1 is pushed to the required distance, it stops, effectively enhancing the stability and smoothness during the detection process of the thrust detection device, reducing the serious injury to the hand caused by the accidental flying out of parts when holding the thrust device for detection. Place the welded part on the top of the placement plate 4 for thrust detection. The placement plate 4 provides a stable surface, which helps to maintain the stability of the welded part during the thrust detection process, thereby improving the accuracy of detection. By placing the welded part on the placement plate 4, the welded part can be prevented from directly contacting the hard object surface, reducing the damage to the welded part during the detection process. Using the placement plate 4 effectively reduces the bending and reaching actions of the operator during thrust detection, thereby reducing the safety risk caused by improper operation. When performing thrust detection on the welded part, combine with the scale 5 to push the cylinder 1 to an appropriate distance and perform detection with this thrust. The magnitude of the thrust can be directly read through the scale on the scale 5, providing relatively accurate measurement data for the operator. The scale on the scale 5 can also help record the measured thrust value, facilitating subsequent data analysis and comparison, enhancing the accuracy of the device. The setting of the support column 6 can bear and disperse the pressure from above, enhancing the stability of the entire structure, reducing the damage caused by the device tipping over, and at the same time improving the aesthetics of the device. Place some commonly used tools and parts inside the toolbox 7. The toolbox 7 can effectively protect the tools from damage and rust, extending the service life of the tools; the setting of the toolbox 7 makes it easier for the operator to find the required tools, thereby reducing the search time, improving work efficiency, and at the same time increasing the aesthetics and practicality of the device.
