Description

Technical Field

[0001] The utility model relates to the technical field of microsphere debonding testers, in particular to a microsphere debonding strength machine which is convenient for adjusting the angle of a microscope. Background Art

[0002] The microsphere debonding tester works by attaching a solidified liquid resin to an extremely fine single fiber in a glassy state. The fiber and resin are then stretched to determine the interfacial shear strength between them, and the process of resin-fiber separation is recorded using a high-power microscope. It can measure the compatibility between fiber materials and matrix resins, the correlation between interfacial shear strength and time, determine the quality of fiber surface treatment methods and explore their mechanisms, the effect of modifiers on the bond strength between fiber and matrix, and mechanically characterize the bond strength between fiber and matrix. This provides essential test data for carbon fiber performance evaluation and composite material research, helping to address micromechanical issues in carbon fiber composite material research.

[0003] The existing high-power microscope used in microsphere debonding and strength testing machines is mounted by attaching its base to a mounting rod. Loosening the screws on the base allows the microscope to be rotated to adjust the optimal observation angle, and tightening the screws on the base locks the microscope. However, this adjustment method relies entirely on manual operation to change the observation angle, making it difficult to precisely adjust the angle. Furthermore, when rotating to a specific angle, the microscope can easily shift during the tightening process, causing the target angle to change. Therefore, improvements to this structure are needed. Utility Model Content

[0004] The purpose of the utility model is to provide a microsphere debonding and strengthening machine. The utility model is convenient for adjusting the observation angle of the microscope, thereby improving the convenience of using the microsphere debonding and strengthening machine.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a microsphere debonding strength machine, comprising a base, an XY-axis movable guide rail, a micrometer seat, a knife-edge micrometer, a lifting mechanism, a tension sensor and a clamp, wherein the XY-axis movable guide rail and the lifting mechanism are arranged on the base, the micrometer seat is arranged on the movable end of the XY-axis movable guide rail, and the knife-edge micrometer is installed on the micrometer seat; a traveling plate is provided on the movable end of the lifting mechanism, the tension sensor is installed on the traveling plate, a connecting piece is provided on the detection end of the tension sensor, the clamp is arranged on the connecting piece, and the clamp is arranged on the knife-edge micrometer. The base is provided with a connecting rod on the side thereof, a connecting cross rod is provided on the connecting long rod, and a microscope is mounted on the connecting cross rod; a gear damping member is provided on the connecting cross rod, and the gear damping member comprises a cylindrical base, and a plurality of elastic protrusions are evenly arranged on the outer periphery of the cylindrical base along the circumferential direction; a lens seat is provided on the microscope, and a through hole for the gear damping member to pass through is provided on the lens seat, and V-shaped positioning grooves are evenly arranged on the inner wall of the through hole along the circumferential direction, and a damping protrusion is formed between every two adjacent V-shaped positioning grooves, and the elastic protrusions on the outer periphery of the cylindrical base are embedded in the corresponding V-shaped positioning grooves.

[0006] By adopting the above technical solution, when adjusting the angle of the microscope, the microscope is directly rotated, and the gear damping member arranged on the connecting crossbar prompts the microscope to rotate intermittently at the same angle. That is, during the rotation of the microscope, the elastic protrusion on the gear damping member switches between two states: embedded in the V-shaped positioning groove and deformed by the damping protrusion. When the optimal observation angle is reached, the elastic protrusion can be stably positioned in the V-shaped positioning groove due to the action of the damping protrusion, thereby ensuring the stability of the microscope after the angle is adjusted. Since the angle of each interval rotation is the same, the adjustment is very convenient, which improves the convenience of using the microsphere debonding strength machine.

[0007] The utility model is further configured such that the outer circumference of the columnar base is protruded outward with a plurality of arc-shaped elastic parts, the number of which is equal to the elastic protrusions, the elastic protrusions are arranged on the corresponding arc-shaped elastic parts, and a clearance gap is provided between the arc-shaped elastic parts and the columnar base.

[0010] By adopting the above technical solution, the microscope can be locked and installed, and the assembly and disassembly operations are very convenient, which is beneficial to the early assembly and the later disassembly and maintenance operations.

[0011] The utility model is further configured such that an elastic washer is sandwiched between the locking nut and the limiting ring.

[0012] By adopting the above technical solution, the elastic washer can provide a pre-tightening force for the locking nut, increase the thread friction between the elastic washer and the screw part, and achieve an anti-loosening effect.

[0013] The utility model is further configured such that the end of the screw portion is threadedly connected with a protective screw sleeve.

[0014] By adopting the above technical solution, the protective screw sleeve plays a protective role, preventing the operator from being injured by hitting the screw part with his hand when operating the machine.

[0015] The utility model is further configured as follows: a first connecting sleeve is provided on the side of the base, one end of the connecting long rod is inserted in the first connecting sleeve, and a first locking screw is threadedly connected to the side of the first connecting sleeve. When the first locking screw is tightened, the inner end of the first locking screw is pressed against the outer wall of the connecting long rod. A second connecting sleeve is provided at one end of the connecting cross rod, the second connecting sleeve is sleeved on the outer periphery of the connecting rod, and a second locking screw is threadedly connected to the second connecting sleeve. When the second locking screw is tightened, the inner end of the second locking screw is pressed against the outer wall of the connecting long rod.

[0016] By adopting the above technical solution, the angle adjustment of the connecting long rod and the connecting cross rod can be realized, the position of the microscope can be quickly and roughly adjusted, and it is also convenient for later storage.

[0017] The utility model is further configured as follows: the lifting mechanism includes a housing, a driving motor arranged at the bottom of the housing, and a transmission screw linked to the motor shaft of the driving motor; the housing is also provided with a guide rod extending in a direction parallel to the transmission screw; the traveling plate is provided with a screw nut cooperating with the transmission screw and a guide hole cooperating with the guide rod.

[0018] By adopting the above technical solution, the driving motor drives the transmission screw to rotate, so that the traveling plate is raised and lowered, and the fiber and resin are stretched. The structure is simple and reliable, and the operation is very stable. BRIEF DESCRIPTION OF THE DRAWINGS

Action; the side of the base 1 is also provided with a connecting long rod 10, the connecting long rod 10 is provided with a connecting cross rod 11, and a microscope 12 is installed on the connecting cross rod 11; the connecting cross rod 11 is provided with a gear damping member 13, the gear damping member 13 can be made of plastic material, the gear damping member 13 includes a cylindrical base 14, the outer periphery of the cylindrical base 14 is evenly provided with a plurality of elastic protrusions 15 along the circumferential direction, and a mirror seat 16 is provided on the mirror seat 16 for the gear damping member 13 to pass through, and the inner wall of the through hole 17 is evenly provided with V-shaped positioning grooves 18 along the circumferential direction, and a damping protrusion 19 is formed between each adjacent two V-shaped positioning grooves 18, and the elastic protrusions 15 on the outer periphery of the cylindrical base 14 are embedded in the corresponding V-shaped positioning grooves 18.
