Description

Technical Field

[0001] This utility model belongs to the field of testing fixtures, and in particular relates to a fracture testing fixture for a shuluo instrument. Background Technology

[0002] Due to usage requirements and structural characteristics, some products have easily broken parts. Therefore, it is necessary to test the easily broken parts during factory sampling to ensure the performance stability of the products. During the fracture test, the product to be tested needs to be fixed in place before the test is conducted. For products with irregular shapes, it is usually not convenient to fix and clamp them.

[0003] Therefore, there is an urgent need for a tooling that can perform fracture tests on products under test, especially those with irregular shapes. Utility Model Content

[0004] In view of this, the present invention aims to provide a fracture testing fixture for a shuluo instrument, so as to at least solve one of the problems in the background art.

[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0006] The fracture test fixture for the Shuluo instrument includes a test fixture body and a product to be tested. The test fixture body is equipped with a transmission mechanism, a measuring mechanism and a fixing mechanism, and the product to be tested is fixed by the fixing mechanism.

[0007] The transmission mechanism includes a transmission base and a test head. The test head abuts against a preset position on the product under test, and the transmission base drives the test head to apply force to the product under test.

[0008] The measuring mechanism is located between the transmission base and the test head and is used to detect the magnitude of the applied force;

[0009] The product to be tested includes a base and a head. The grip is located between the base and the head. A connecting component is installed in the grip. The head is mounted on the base using the connecting component.

[0010] Furthermore, a transmission assembly and a support base are provided below the transmission base. The transmission assembly includes a transmission screw, one end of which is connected to an external power source, and the other end is rotatably connected relative to the support base.

[0011] A transmission slider is fitted onto the transmission lead screw, and the bottom of the transmission seat is connected to the transmission slider;

[0012] The transmission screw drives the transmission slider to move in the horizontal direction.

[0013] Furthermore, the support base is provided with no less than two guide rods that are parallel to the transmission screw, and the bottom of the transmission base is provided with corresponding guide blocks, which are sleeved inside the guide rods;

[0014] Guide rods are located on both sides of the transmission lead screw.

[0015] Furthermore, external power sources include servo motors or handwheels.

[0016] Furthermore, the measuring mechanism includes a pressure sensor, which is mounted on the transmission base.

[0017] Furthermore, the test head has a first contour pad on the side facing the product under test, and the shape of the first contour pad matches the shape of the preset position of the product under test.

[0018] The first contour pad is detachably connected to the test head.

[0019] Furthermore, the fixing mechanism includes a clamping block and a fixing base. The clamping block has two pieces, which are arranged opposite each other and detachably connected. There is a fixing chamber between the two clamping blocks for accommodating the base. The base is clamped in the fixing chamber by the two clamping blocks.

[0020] The bottom of the outer wall of the clamping block is recessed inward and has a limiting groove. The fixing seat is detachably connected to the base plate. The fixing seat extends towards the limiting groove and has a limiting flange structure. The clamping block is fixed to the base plate by the limiting flange structure and the limiting groove.

[0021] Furthermore, side limiting blocks are provided at both ends of the limiting flange structure to limit the clamping block laterally.

[0022] Furthermore, a second contour pad is provided at the contact point between the fixed chamber and the base, and the shape of the second contour pad matches the shape of the base of the product under test.

[0023] The second contour pad is detachably connected to the clamping block using bolts.

[0024] Compared with the prior art, the fracture testing fixture for the Shuluo instrument described in this utility model has the following beneficial effects:

[0025] The fracture testing fixture for the Shuluo instrument described in this utility model first selects an appropriate contour pad and uses a fixing mechanism to fix the product to be tested. Then, the test head applies force to a specific part of the product to be tested from the side. During the process, the applied force is measured by a measuring mechanism. As the applied force increases, the magnitude of the applied force when the specific part breaks is obtained, which facilitates the acquisition of performance parameters of this batch of products.

Detailed Implementation

[0032] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0033] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0034] This invention discloses a fracture testing fixture that can be used to perform fracture testing on products to be tested, and in particular, it can be used to perform fracture testing on the "Hezhiyoude Portable Shuluo Instrument".

[0035] Taking the Shuluoyi device as an example, the product under test usually requires holding the head 5 of the Shuluoyi device during use, and using the functional components set in the base 4 to perform physiotherapy on the human body. The specific type or category of the functional components is irrelevant to this case. The gripping part 6 is located between the base 4 and the head 5. The gripping part 6 is equipped with a connecting component 7. During the above-mentioned use, the gripping part 6 / connecting component 7 will be subjected to torque due to the human hand gripping and bending. When the torque is too large, it will cause the connecting component 7 to be damaged. The purpose of this device is to use this tooling to fix the product under test, and then apply external force. During the process, the pressure sensor is used to detect the magnitude of the applied force. As the applied force gradually increases, the endurance limit when the connecting component 7 breaks is finally read, thereby completing the sampling inspection of this batch of products.

[0036] This solution includes a transmission mechanism, a measuring mechanism 3, and a fixing mechanism, which is used to fix the product to be tested.

[0037] The transmission mechanism includes a transmission base 1 and a test head 2. The test head 2 abuts against a preset position of the product to be tested, and the transmission base 1 drives the test head 2 to apply force to the product to be tested.

[0038] The measuring mechanism 3 is located between the transmission base 1 and the test head 2, and is used to detect the magnitude of the applied force.

[0039] The product under test includes a base 4 and a head 5. The gripping part 6 is located between the base 4 and the head 5. A connecting component 7 is installed inside the gripping part 6. The head 5 is mounted on the base 4 using the connecting component 7. As can be seen from the figure, the gripping part 6 is designed to improve comfort during hand gripping. However, since the gripping part 6 is relatively thin compared to the overall instrument, the gripping part 6 and the internal connecting component 7 are prone to breakage when excessive force is applied during use. The main testing part of this device is the aforementioned gripping part 6 and the internal connecting component 7.

[0040] During use, firstly, appropriate first contour pad 21 and second contour pad 122 are selected according to the specific shape of the product to be tested. The purpose is to ensure that the product to be tested can be stably fixed on the fixture. Then, the test head 2 applies force from the side to a specific part of the product to be tested (e.g., the head 5 of the massager). During the process, the magnitude of the applied force is recorded using existing measuring mechanisms 3, such as pressure sensors. The specific force magnitude detection can be achieved using existing technology and is not considered an innovation of this case. The specific force application method can utilize the handwheel 11 structure shown in the figure, or it can utilize an electric power source, such as an electric push rod, to apply force.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
