Description

A modular multi-purpose force measurement platform

Technical Field

The present application relates to the technical field of force testing, and in particular to a modular multi-purpose force measuring platform.

Background technique

In vehicle-mounted power supplies, metal springs are often used to apply pressure to the power module inside to fix it on the radiator. The magnitude of the pressure affects the heat exchange efficiency between the power module and the radiator, and thus affects the working efficiency of the vehicle-mounted power supply. The connector plays the role of connecting the internal and external communications and power of the device, and the magnitude of its pulling force also greatly affects the reliability of the device operation.

Therefore, in the design and production of vehicle power supplies, it is usually necessary to test the pull-out force and elastic force of its internal connectors and shrapnel. Existing test tools can often only test a single product. When it is necessary to test multiple different parts of a product, the entire test equipment can only be replaced to achieve the purpose. The replacement process is cumbersome and increases production costs.

Specifically, the currently available structural spring force measuring equipment mainly uses a single dynamometer and test tooling to test the force condition of the object being measured. For example, the Chinese utility model patent application number is CN202220846417.X and the Chinese invention publication number is CN103454156B, which is not compatible with multiple types of dynamometers and multiple categories of objects being measured.

Detailed ways

The technical solution in the embodiment of the present application is to solve the problems raised in the above background technology, and the overall idea is as follows:

Embodiment 1:

Please refer to FIG1 , a modular multi-purpose force measuring platform includes a force meter 1, a force meter quick adapter plate 3 is detachably provided on the bottom surface of the force meter 1, an X-axis displacement fine-tuning platform 5 is provided at the bottom of the force meter quick adapter plate 3, and a platform base 11 is provided at the bottom of the X-axis displacement fine-tuning platform 5, a force measuring end of the force meter 1 is provided with a force meter push-pull head 6 in contact with the platform base 11, a push-pull module mounting platform 7 is also installed on the outside of the force meter push-pull head 6, and a push-pull module 8 is detachably fixed on the outside of the push-pull module mounting platform 7, a modular test body fixing seat 10 is detachably provided on one side of the platform base 11 close to the push-pull module 8, and a test object 9 pushed and pulled by the push-pull module 8 is detachably provided on the modular test body fixing seat 10. Among them, the test object 9 can be selected as a test spring.

In this embodiment, the X-axis displacement fine-tuning platform 5 can indirectly drive the dynamometer 1 to push or pull the push-pull module mounting platform 7, so as to cause the push-pull module 8 to push or pull the object 9 mounted on the modular test body fixing seat 10. The force measurement condition of the object 9 can be determined by comparing the displacement change of the X-axis displacement fine-tuning platform 5 with the value of the dynamometer 1.

When a different object 9 is replaced, the modular test body fixing seat 10 can be replaced to achieve the purpose of rapid replacement.

In order to meet the needs of pushing and pulling different objects 9 to be measured, the force-bearing mode of the object to be measured can be quickly changed by replacing the push-pull module 8 on the push-pull module mounting platform 7 .

Please refer to Figures 1 and 4. The X-axis displacement fine-tuning platform 5 includes a dynamometer mounting base 5.1 that is detachably fixed to the dynamometer quick adapter plate 3. The bottom of the dynamometer mounting base 5.1 is slidably connected to a displacement platform fixing base 5.2 that is detachably mounted on the platform base 11. A bump A and a bump B are respectively installed on the same side of the dynamometer mounting base 5.1 and the displacement platform fixing base 5.2. A push rod 5.3 that movably passes through the bump B and is rotatably fixed to the bump A is installed on the side of the dynamometer mounting base 5.1, and the push rod 5.3 has a scale.

It should be noted that the protrusion A and the protrusion B are fixedly connected to the dynamometer mounting seat 5.1 and the displacement platform fixed base 5.2 respectively, and as can be directly seen in Figure 4, the axis of the hole on the protrusion B and the protrusion A is located on the same straight line. It should also be noted that a bearing (not shown) is embedded in the hole of the protrusion A, and the inner ring of the bearing is designed with an interference fit with one end of the push rod 5.3. Rotating the other end of the push rod 5.3 can drive the protrusion A to move on the X-axis, and since the push rod 5.3 is provided with a scale, the displacement of the dynamometer 1 can be clearly observed.

The push-pull module mounting platform 7 is designed in a "7" shape, and mounting holes 7.1 are longitudinally opened at equal intervals on both sides of the lower section. Screw holes A are opened in pairs transversely on the push-pull module 8, and M4 fixing screws 2 are provided. The M4 fixing screws 2 pass through the mounting holes 7.1 and are screwed into the screw holes A. Specifically, as shown in the enlarged partial figure of FIG. 1, it can be known that the arrangement of the mounting holes 7.1 on the push-pull module mounting platform 7 can assist in adjusting the fixed position of the push-pull module 8 on the push-pull module mounting platform 7, and indirectly adapt to the test of different objects 9 to be tested.

Please refer to Figure 3, the push-pull module 8 is designed in a rectangular block shape. In the pushing state, the push-pull module 8 presses against and pushes the upper section of the object 9 to one side to test the elastic force. That is, the push-pull module 8 of the above shape can measure the thrust of the object 9 to be tested.

Please refer to FIG. 1 . The platform base 11 is provided with screw holes B arranged at equal intervals, and is also provided with M4 fixing screws 2. The modular test body fixing seat 10 is provided with through holes A in pairs, and the M4 fixing screws 2 pass through the through holes A and are screwed into the corresponding screw holes B. Specifically, according to the position where the object 9 to be tested needs to be installed, the position is found by using the screw holes B arranged on the platform base 11 and the corresponding through holes A on the modular test body fixing seat 10, and then fixed with the M4 fixing screws 2, so that the detachable installation of the modular test body fixing seat 10 is completed, which is also convenient for replacing different objects 9 to be tested.

It should also be noted that a screw hole F is also provided on the modular test body fixing seat 10, and is also equipped with an M4 fixing screw 2. A through hole E is opened on the object to be tested 9. The M4 fixing screw 2 passes through the through hole E to be fixed to the screw hole F, so that the modular test body fixing seat 10 and the object to be tested 9 can be detachably installed. When disassembling and replacing the object to be tested 9, the object to be tested 9 can also be disassembled separately; the modular test body fixing seat 10 can also be disassembled.

From the perspective of Figures 1 and 3, it can be seen that the upper part of the modular test body fixing seat 10 is also connected to the limit rods in pairs, and the object to be measured 9 is also provided with limit holes adapted to the limit rods in pairs. When installing the object to be measured 9, the limit rods are pre-inserted into the limit holes of the object to be measured 9, so that the pre-positioning of the object to be measured 9 can be achieved.

Please refer to FIG. 1 , the dynamometer push-pull head 6 is also designed in a "7" shape, and the upper section of the dynamometer push-pull head 6 is provided with screw holes C in pairs, and is also equipped with M4 fixing screws 2, and the upper section of the push-pull module installation platform 7 is provided with through holes B in pairs, and after the outer side of the dynamometer push-pull head 6 is fitted with the inner side of the push-pull module installation platform 7, the M4 fixing screws 2 pass through the through holes B and are screwed into the corresponding screw holes C. Specifically, the dynamometer push-pull head 6 is conveniently detachably installed on the push-pull module installation platform 7 by using the M4 fixing screws 2 to pass through the through holes B and be screwed into the corresponding screw holes C.

Please refer to Figure 1, the inner side of the dynamometer push-pull head 6 is provided with an internal threaded tube, and one side of the outer end of the dynamometer 1 is provided with an external threaded rod adapted to the internal threaded tube, and the two can be used to realize the detachable installation of the dynamometer push-pull head 6 and the dynamometer 1. The later replacement cost is reduced.

Please refer to FIG1 . The dynamometer quick adapter plate 3 has a plurality of through holes C near the outer side, and the bottom edge of the dynamometer 1 has a plurality of screw holes D corresponding to the positions of the through holes C, and is provided with M3 fixing screws 4, which pass through the through holes C and are screwed into the corresponding screw holes D. Specifically, the function of the M3 fixing screws 4 is to complete the detachable installation of the dynamometer quick adapter plate 3 and the dynamometer 1, so that a variety of different types of dynamometers 1 can be easily installed.

Please refer to FIG. 1 , the dynamometer quick adapter plate 3 is also provided with a plurality of through holes D, and the dynamometer mounting seat 5.1 is provided with a plurality of screw holes E at positions corresponding to the through holes D, and is also provided with M4 fixing screws 2, which pass through the through holes D and are screwed into the corresponding screw holes E. Specifically, the function of the M4 fixing screws 2 here is to quickly and detachably fix the dynamometer quick adapter plate 3 to the dynamometer mounting seat 5.1.

When using this application:

1. The installation method is as follows:

S1, the dynamometer 1 is fixed on the dynamometer quick adapter plate 3 by M3 fixing screws 4;

S2, the quick adapter plate 3 is fixed to the dynamometer mounting seat 5.1 on the X-axis displacement fine-tuning platform 5 by means of the M4 fixing screws 2;

S2. The modular test body fixing seat 10 is fixed to the platform base 11 by M4 fixing screws 2.

2. The operation mode is as follows:

The dynamometer mounting seat 5.1 can be moved by the push rod 5.3, thereby driving the dynamometer 1 to move left and right. The push rod 5.3 has a scale to calculate the platform displacement. When the push rod 5.3 is rotated, the protrusion A drives the dynamometer mounting seat 5.1 to move, and at the same time, the dynamometer mounting seat 5.1 drives the push-pull module mounting platform 7 to move. Since its bottom is in contact with the platform base 11, it will not rotate. Further drive the push-pull module 8 to move, thereby applying a force in the direction of movement to the object 9 to be measured. According to Newton's law, the force applied to the object 9 to be measured can be read on the dynamometer and can correspond to the displacement of the push rod 5.3.

Embodiment 2:

The difference from Example 1 is:

Please refer to Figure 2, the push-pull module 8 is an inverted L-shaped plate design. In the pulling state, the push-pull module 8 is clamped on the upper section of the object 9 to be tested and pulls it to one side to test the elastic force. That is, the push-pull module 8 of the above shape can measure the pulling force of the object 9 to be tested.

For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present application.
