Description

Technical Field

[0001] The utility model relates to the technical field of composite material testing instruments, in particular to a biological composite material processing testing instrument with a protective effect. Background Art

[0002] The composite material testing instrument is an essential facility for conducting tensile tests on biocomposite materials during processing. It can clamp the processed biocomposite materials and pull the composite materials in two opposite directions, thereby facilitating the testing of the tensile resistance of the composite materials.

[0003] For example, announcement number CN220418985U discloses a biocomposite material processing test instrument, including a support, a clamping seat is installed on the top of the support. The utility model is equipped with a clamping seat, and the clamping seat can stably support the cone basket. After clamping the two ends of the composite material, the staff can move the protective cover from the inside of the cone basket to the outside by means of the handle upwards, and pull the protective cover downwards to unfold the protective cover and fit it on the outside of the two clamping seats, and then move the handle to the inside of the barb handle at the corresponding position so that the barb handle and the handle are engaged with each other, thereby achieving the function of fixing the protective cover, so that the protective cover can cover the two clamping seats and the outside of the clamped composite material. At the same time, the protective cover has a certain elasticity and can be deformed under the action of external force, so that the protective cover can provide protection to prevent the composite material from breaking and injuring surrounding staff.

[0004] However, when the processing test instrument is in use, although the baffle can protect the operator when performing tensile testing on biological materials, when testing the biological materials, the materials are only tested by stretching, and the materials are not rotated while being stretched. This results in poor rotational testing effects, which easily reduces the accuracy of the test data for the biological materials. Utility Model Content

[0005] In view of the above problems in the prior art, the utility model provides a biocomposite material processing test instrument with a protective effect, which solves the problem that the prior biocomposite material processing test instrument cannot perform rotational testing on the material while performing testing on the stretched material.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] Provided is a biocomposite material processing test instrument with a protective effect, comprising a device body, a lifting assembly located on the top surface of the device body, an upper clamping piece rotatably arranged on the lifting assembly, a lower clamping piece located directly below the upper clamping piece, and at least one baffle located on one side of the second clamping piece; the lower clamping piece is rotatably arranged on the top surface of the device body, the upper clamping piece and the lower clamping piece are respectively used for clamping two ends of a material; and the bottom end of each baffle is rotatably arranged on the top surface of the device body.

[0008] The working principle of this scheme is: use the upper clamp and the lower clamp to clamp the two ends of the material respectively, drive the upper clamp to move upward through the lifting assembly, and while stretching the material, the upper clamp and the lower clamp can rotate relative to each other, so as to apply torque to the material while stretching the material, thereby improving the detection effect. At the same time, the setting of the baffle can avoid accidental injury to the operator due to loose materials, and play a protective role.

[0009] Furthermore, the lower clamping member includes a first fixed shell, the bottom surface of the first fixed shell is fixedly connected to the first rotating shaft, the first rotating shaft is rotatably arranged on the device body, and two clamping rods are movably arranged on the top surface of the first fixed shell.

The first servo motor drives the first worm to rotate, and the second worm drives the first worm wheel to rotate, so that the first worm wheel drives the first rotating shaft to rotate. The transmission connection between the first worm and the first worm wheel has a high transmission ratio, which is greater than the transmission ratio of traditional gears, and can provide a large reduction ratio in a very limited space. The contact area between the first worm and the first worm wheel is large, so the load is distributed more evenly on the contact surface, which helps to withstand a large load without being easily damaged.

[0012] Furthermore, the upper clamping member and the lower clamping member have the same structure. The upper clamping member includes a second fixed shell and a second rotating shaft. Two clamping rods are movably arranged on the bottom surface of the second fixed shell. The top surface of the second fixed shell is fixedly connected to the second rotating shaft. The top end of the second rotating shaft is rotatably arranged on a motor on the lifting assembly.

[0013] Furthermore, the rotation centers of the first rotating shaft and the second rotating shaft are located on the same vertical line.

[0014] Furthermore, two baffles are arranged on the top surface of the device body, and the two baffles are symmetrically located at the front and rear sides of the lower clamping member.

[0015] Furthermore, a rotating rod is provided at the bottom of both sides of each baffle, and the two rotating rods are respectively rotatably arranged on the two supporting blocks on the top surface of the device body, and one end of a rotating rod passes through the supporting block and is fixedly connected to the second worm gear, the second worm gear is meshedly connected with the second worm, and the two ends of the second worm gear are respectively rotatably arranged on the two side walls of the U-shaped plate, and one end of the second worm gear is exposed outside the U-shaped plate. Manually rotating the second worm gear drives the second worm gear, thereby driving the baffle to rotate, and the transmission connection between the second worm gear and the second worm gear has good self-locking performance, the second worm gear can drive the second worm gear to rotate, and the second worm gear cannot drive the second worm gear, thereby realizing the self-locking of the baffle, and facilitating the adjustment of the angle of the baffle.

[0016] Furthermore, a knob is fixed on the exposed end of the second worm, and the arrangement of the knob facilitates manual driving of the second worm.

[0017] Furthermore, the central axis of the second worm is arranged horizontally, and the horizontally arranged second worm is convenient for the test personnel to apply force to rotate.
