Description
Technical Field
[0001] The utility model belongs to the technical field of test piece cutting machines, and in particular relates to an automatic calibrated test piece cutting machine. Background Art
[0002] A test strip cutter is a device used to cut material test strips. It is primarily used in fields such as materials science, chemical analysis, and quality inspection. It cuts raw materials into test strips of specific sizes and shapes for subsequent performance testing and analysis. For example, in the research and development and production of materials such as plastics, rubber, metal, and paper, a test strip cutter is required to produce standard-sized test strips for mechanical properties testing, such as tensile, flexural, and impact tests. This process is typically performed using a power-driven cutting tool (such as a blade or saw). Cutting size and accuracy can be adjusted manually or automatically. Some advanced test strip cutters are also equipped with CNC systems for automatic dimensional calibration, enabling precise setting of cutting parameters to ensure consistent test strip dimensions.
[0003] However, the loading platform of the specimen cutting machine often has difficulty in firmly clamping the object to be cut or even in effectively fixing it due to the diversity of the shapes of the clamped objects. In this state, the object is likely to be displaced or even fall off due to vibration during the cutting process, which poses a certain safety risk and causes considerable trouble for subsequent operations. To this end, the inventors have introduced an automatic calibration specimen cutting machine that can adapt to various object shapes to solve the above-mentioned problems. Utility Model Content

[0023] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention.
[0024] like Figures 1 to 6 As shown, an automatically calibrated specimen cutting machine includes a cutting machine body 1, a transverse slide 10 and an object to be cut 15. A clamping mechanism is provided at the upper end of the transverse slide 10. The clamping mechanism includes a cross clamp 11 and a slotted threaded rod 21. An anti-slip strip 14 is fixedly connected to the outer edge of the cross clamp 11, and a rotating connector is fixedly connected to the center position of the lower end of the cross clamp 11. This rotating connector corresponds to the groove provided at the upper end of the slotted threaded rod 21 and is movably connected thereto. An adjusting knob 13 is threadedly sleeved on the rod body of the slotted threaded rod 21.
[0025] In this setting, the utility model adopts the design of a specially shaped clamping piece, which will automatically adapt to the shape of the object during the clamping process and find a more suitable clamping fixed point. At the same time, an anti-slip strip is set on the clamping piece to prevent the object from being displaced or falling off due to vibration during the cutting process, thereby increasing the safety of the operation; the function of the anti-slip strip 14 can prevent the object from being displaced or falling off during cutting.
[0026] like Figures 1 to 6 As shown, in a specific embodiment, a groove is longitudinally provided on the rod body of the slotted threaded rod 21, and a limiting support plate 12 is movably sleeved on the rod body of the slotted threaded rod 21, and a protrusion is fixedly connected to the inner side of the opening of the limiting support plate 12, and this protrusion corresponds to the groove provided on the slotted threaded rod 21 and is slidably sleeved therewith, and the lower end of the slotted threaded rod 21 is fixedly connected to the slider 22 through a connecting rod.
[0027] In this setting, the function of the limiting support plate 12 is to support the object 15 to be cut to prevent it from sliding downward due to gravity or during cutting, and the function of the adjusting knob 13 is to adjust the height of the limiting support plate 12 to adapt to different cutting requirements.
[0028] like Figures 1 to 6 As shown, in a specific embodiment, a square slide groove 17 is provided inside the transverse slide 10, and a rectangular slider 19 is slidably sleeved inside the square slide groove 17. Slide grooves 20 are provided at both ends of the upper surface of the rectangular slider 19, and the slide grooves 20 correspond to the slider 22 and are slidably sleeved therewith.
[0029] In this setting, as the rectangular slider 19 slides, the inclined slot 9 causes the slider 22 to converge toward the middle. At this time, when the cross clamp 11 contacts the object to be cut 15, it will rotate, and finally the two vertical edges will squeeze the surface of the object to be cut 15 at the most appropriate angle to fix it.
[0030] like Figures 1 to 6 As shown, in a specific embodiment, an inclined groove 9 is provided on the upper surface of the transverse slide 10, which corresponds to the connecting rod between the lower end of the slotted threaded rod 21 and the slider 22, and is slidably connected thereto, and a motor 16 is fixedly connected to the middle position of one side of the transverse slide 10, and a bidirectional threaded rod 18 is fixedly connected to the shaft of the motor 16; the bidirectional threaded rod 18 passes through the transverse slide 10 and the rectangular slider 19, and is movably connected to the transverse slide 10, and at the same time, the bidirectional threaded rod 18 is threadedly connected to the rectangular slider 19.
[0031] In this configuration, when using the device, the object to be cut 15 is first suspended above the transverse slide 10, and then the motor 16 is started. The motor 16 drives the bidirectional threaded rod 18 to rotate, causing the rectangular slider 19 to slide inward.
[0032] like Figures 1 to 6 As shown, in a specific embodiment, a control panel 2 is fixedly installed on the front panel of the cutting machine body 1, and a cutting chamber 5 is fixedly connected to one side of the cutting machine body 1, a visible cover 3 is movably installed on the upper end of the cutting chamber 5, and a cutting head 4 is installed on one side of the cutting chamber 5 of the cutting machine body 1; a longitudinal slide rail 8 is fixedly connected to the bottom of the cutting chamber 5, a longitudinal slide plate 7 is slidably installed on the track of the longitudinal slide rail 8, and a transverse slide rail 6 is fixedly connected to the upper surface of the longitudinal slide plate 7, and the transverse slide rail 6 corresponds to the T-slot opened at the lower end of the transverse slide plate 10, and is slidably engaged with it.
[0033] In this setting, the purpose of designing the cutting chamber 5 is to isolate the working area from the outside world to make the operation safer, and the design of the visual cover 3 is to enable the operator to observe the internal cutting situation from the outside.
[0034] The implementation principle of an automatic calibration test piece cutting machine of this embodiment is as follows:
[0035] The utility model adopts a design of a specially shaped clamping piece, which automatically adapts to the shape of the object during the clamping process and finds a more suitable clamping fixed point. At the same time, an anti-slip strip is provided on the clamping piece to prevent the object from being displaced or falling off due to vibration during the cutting process, thereby increasing the safety of the operation.
[0036] When using this equipment, first suspend the object 15 to be cut above the horizontal slide 10, and then start the motor 16. The motor 16 drives the bidirectional threaded rod 18 to rotate, causing the rectangular slider 19 to slide inward. While the rectangular slider 19 slides, the oblique slide 9 causes the slider 22 to converge to the middle. At this time, when the cross clamp 11 contacts the object to be cut 15, it will rotate, and finally the two vertical edges will squeeze the surface of the object to be cut 15 at the most appropriate angle to fix it. The function of the anti-slip strip 14 can prevent the object from being displaced or falling off during cutting. The function of the limiting support plate 12 is to support the object to be cut 15 to prevent it from sliding downward due to gravity or cutting, and the function of the adjusting knob 13 is to adjust the height of the limiting support plate 12 to meet different cutting requirements.
