Description

Technical Field

[0001] This application relates to the field of mechanical clamping technology, and in particular to a clamping device with a constant adjustable loading force. Background Technology

[0002] Angled surface bonding sample preparation technology mainly involves precisely aligning and firmly bonding the angled surfaces of two or more bonding substrates using adhesives to form samples with specific structures and functions. It is an indispensable technology in materials science, mechanical engineering, and many industrial fields. In this bonding method, the angled surfaces must be aligned at a 90-degree angle to prevent displacement of the bonded surfaces.

[0003] Currently, simple clamp templates are commonly used in the process of preparing samples for inclined bonding. As a result, the operation is cumbersome and the accuracy is not high when adjusting the loading force. It is difficult to ensure that the loading force is constant during the loading process, which results in uneven distribution of adhesive and low bonding strength, thus affecting the accuracy and efficiency of sample preparation.

[0004] Regarding the aforementioned technologies, the inventors believe that there is a problem that the loading force cannot remain relatively stable during the inclined plane bonding sample preparation process. Utility Model Content

[0005] To avoid the problem of unstable loading force during inclined bonding sample preparation, this application provides a fixture with a constantly adjustable loading force.

[0006] The clamp for a constantly adjustable loading force provided in this application adopts the following technical solution:

[0007] A clamp with a constant adjustable loading force includes an inner frame for placing an adhesive substrate and an outer frame sleeved outside the inner frame. The outer frame is characterized in that a rotating shaft for applying a loading force is threaded to the top end along the height direction, and the rotating shaft is provided with a rotating component for driving the rotating shaft to rotate.

[0008] By adopting the above technical solution, during the inclined bonding sample preparation process, a loading force is provided along the rotation axis of the rotating component. When the appropriate constant loading force is adjusted, the rotating component stops rotating, making the adjustment of the loading force more convenient and realizing an adjustable constant loading force.

[0009] Preferably, a sensor for detecting the magnitude of the applied force is provided at one end of the rotating shaft located in the inner frame.

[0010] By adopting the above technical solution, when the rotating shaft of the rotating component provides loading force, the sensor takes a reading, which makes it easy to accurately grasp the magnitude of the loading force. This allows for adjustment according to the specific requirements of inclined bonding, making the adjustment of the loading force more precise.

[0011] Preferably, the rotating component is a spiral turntable, and the spiral turntable is provided with a limiting bolt for fixing the spiral turntable.

[0012] By adopting the above technical solution, a spiral turntable is used to generate loading force through rotation. Once the appropriate constant loading force is adjusted, the spiral turntable is prevented from moving backward by a limit bolt, which further ensures the constant loading force during the bonding and sample preparation process and improves the accuracy of sample preparation.

[0013] Preferably, the inner frame is provided with a fixing component for fixing the adhesive substrate.

[0014] By adopting the above technical solution, the inclined surfaces of the bonding substrate can be precisely aligned and bonded using adhesive, further improving the accuracy of sample preparation.

[0015] Preferably, the fixing component consists of a plurality of fixing screws arranged opposite each other along the periphery of the inner frame.

[0016] By adopting the above technical solution, the adhesive substrate is vertically fixed to the inner frame and precisely aligned using adhesive, thereby improving the efficiency of sample preparation.

[0017] Preferably, the fixing components are arranged in several groups at uniform intervals along the height direction.

[0018] By adopting the above technical solution, the adhesive substrate remains relatively stable during the bonding and sample preparation process, avoiding displacement of the bonded surfaces, further ensuring the perpendicularity and stability of the sample, thereby improving the accuracy and efficiency of sample preparation.

[0019] Preferably, the top and end of the outer frame are respectively configured as grooves that fit the inner frame.

[0020] By adopting the above technical solution, the inner frame can be accurately embedded into the outer frame, achieving a tight fit and stable connection between the inner and outer frames, preventing the inner frame from shaking during the bonding and sample preparation process, and further ensuring the stability and verticality of the fixture.

[0021] Preferably, the spiral turntable is externally equipped with a drive source for driving the spiral turntable to rotate, and the drive source is one of a motor, gear, and belt.

[0022] By adopting the above technical solution, using one of the motor, gears, and belts as the drive source, more automated loading force adjustment is achieved. In addition, the variety of drive sources available can meet the needs of different application scenarios, further improving the practicality of the fixture.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. This application uses a rotating shaft threaded onto the outer frame of the fixture to generate a loading force by using a rotating component to drive the rotating shaft to rotate. When the appropriate constant loading force is adjusted, the rotating component stops rotating, which makes it easier to adjust the loading force of the fixture and further ensures the constant loading force during the bonding sample preparation process. This achieves an adjustable constant loading force. In addition, by providing a sensor for detecting the magnitude of the loading force at one end of the rotating shaft located in the inner frame, the adjustment of the loading force is more precise, further improving the accuracy and efficiency of sample preparation.

[0025] 2. This application improves the stability of the fixture by cooperating with the outer frame and the inner frame. At the same time, by evenly spaced several sets of vertical fixing screws on the outside of the inner frame where the adhesive substrate is placed, the adhesive substrate is vertically fixed to the inner frame, ensuring that the sample remains relatively stable during the bonding and sample preparation process, avoiding displacement of the bonded surface, and further ensuring the perpendicularity and stability of the sample.

[0026] 3. This application achieves more automated loading force adjustment by using one of the following as the drive source: a motor, a gear, and a belt to drive the rotating component to rotate the shaft and provide loading force. In addition, the variety of drive sources available can meet the needs of different application scenarios, further improving the practicality of the fixture. Attached Figure Description

[0032] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0033] This application discloses a clamp with a constantly adjustable loading force, referring to... Figure 1-3It includes an inner frame 1, an outer frame 2, a rotating shaft 3, and a rotating component 4. The rotating component 4 is a spiral turntable 41. The outer frame 2 is sleeved outside the inner frame 1. The rotating shaft 3 is threaded to the top of the outer frame 2. The spiral turntable 41 is disposed at the top of the rotating shaft 3, and the spiral turntable 41 and the rotating shaft 3 are integrally formed. The spiral turntable 41 is provided with a drive source 9, which is a motor.

[0034] During the inclined surface bonding sample preparation operation, the two bonding substrates are aligned and bonded with adhesive and then placed in the inner frame 1. Subsequently, the spiral turntable 41 is driven by a motor to rotate, which in turn drives the rotating shaft 3 to rotate and generate a loading force, making the inclined surface bonding of the two bonding substrates more secure. When the appropriate constant loading force is adjusted, the spiral turntable 41 stops rotating, thereby realizing an adjustable constant loading force and further improving the sample preparation efficiency. In addition, the drive source 4 can be replaced by a gear or a belt in other embodiments. Multiple drive sources can be selected to make the fixture adaptable to different application environments and needs, further enriching the diversity of fixture application scenarios.

[0035] To further improve the accuracy of sample preparation, refer to Figure 2 and Figure 3 The fixture is equipped with a sensor 5 and a limit bolt 6. The sensor 5 is located at the end of the rotating shaft 3, and the limit bolt 6 is located on the spiral turntable 41.

[0036] During the inclined plane bonding sample preparation process, the sensor 5 can accurately and in real time monitor the loading force when the spiral turntable 41 rotates and drives the rotating shaft 3 to generate a loading force, ensuring that the operator can accurately grasp the magnitude of the loading force. When a suitable loading force is detected, the limit bolt 6 is used to prevent the spiral turntable 41 from moving backward, thus maintaining a constant loading force, thereby improving the bonding strength of the sample and further improving the accuracy of sample preparation.

[0037] To further ensure the stability of sample preparation, refer to Figure 3 and Figure 4 The top and end of the outer frame 2 are respectively provided with grooves 8 in areas that are adapted to the inner frame 1, and fixing components 7 are provided around the inner frame 1 along the height direction. The fixing components 7 are multiple fixing screws 71, which are evenly distributed on the four sides of the inner frame 1.

[0038] In actual use of the fixture, multiple fixing screws are set around the inner frame 1. The sample is placed inside the inner frame 1, and the fixing screws 71 are rotated according to the size of the sample. When the sample is adjusted to a suitable position, the fixing screws 71 are stopped, so that the sample is vertically fixed inside the inner frame 1 along the height direction. Then, by setting grooves 8 at the top and end of the outer frame 2, the inner frame 1 can be accurately embedded into the outer frame 2, avoiding the impact on the sample quality caused by the sample shaking inside the inner frame 1 during the bonding and sample preparation process, and further ensuring the verticality and stability of the sample.

[0039] The working process and implementation principle of the fixture with adjustable loading force in Example 1 are as follows: By threading a rotating shaft 3 to the outer frame 2 of the fixture, the rotating shaft 3 is rotated along the rotating part 4 to generate a loading force, thereby achieving an adjustable constant loading force; by setting a sensor 5, the adjustment of the loading force is made more precise, further improving the accuracy and efficiency of sample preparation; at the same time, the outer frame 2 and the inner frame 1 cooperate to ensure the stability and perpendicularity of the fixture, and a fixing component 7 is set on the periphery of the inner frame 1 to further ensure the perpendicularity and stability of the sample; in addition, the fixture is also flexible in use, and a variety of available drive sources 9 can make the fixture meet different application environments and needs.

[0040] The above are preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be covered within the scope of protection of this application.
