Abstract
Description
Technical Field
[0001] This utility model relates to the field of tensile testing machine technology, specifically to a three-dimensional four-axis clamping device and a tensile testing machine. Background Technology
[0002] Currently, the adhesion test of electrode sheets is generally performed using a tensile testing machine.
[0003] The clamping device of an existing tensile testing machine generally includes a base plate and a clamping mechanism for clamping one end of the electrode. The base plate is fixed to the base of the tensile testing machine, and the clamping mechanism is located at the top of the base plate. In actual operation, one end of the electrode is first clamped by the clamping mechanism, and then the other end of the electrode is connected to the connecting mechanism of the tensile testing machine. The connecting mechanism is driven by the power mechanism of the tensile testing machine to move away from the clamping device to apply tensile force to the electrode. During the application of tensile force, the tensile testing machine records the displacement and deformation of the electrode. By measuring the displacement of the electrode under tensile force, the adhesive force of the electrode can be calculated, thus realizing the testing of the adhesive force of the electrode.
[0004] In the above structure, since the base plate is fixed on the base of the tensile testing machine and the clamping mechanism is located at the top of the base plate, the Z-axis position, i.e., the height position, of the clamping mechanism cannot be adjusted, making it unable to adapt to different working conditions and meet usage requirements.

Detailed Implementation
[0025] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.
[0026] Please refer to Figures 1 to 5 An embodiment of this utility model provides a three-dimensional four-axis clamping device, including a fixing plate 10, a support rod 20, a fixing frame 30, and a clamping mechanism 40 for clamping one end of an electrode sheet.
[0027] The fixing plate 10 is used to fix it to the base of the tensile testing machine.
[0028] In this embodiment, the bottom end of the fixing plate 10 is provided with a support leg 11, which is used to fix the tensile testing machine to the base. In this embodiment, there are four support legs 11, which are located at the four corners of the bottom end of the fixing plate 10.
[0029] The fixing plate 10 has a fixing plate mounting hole at its center, passing through its top and bottom ends. The support rod 20 passes through the fixing plate mounting hole of the fixing plate 10 and is threadedly connected to the fixing plate mounting hole. The lower end of the support rod 20 is located below the fixing plate 10, and the upper end of the support rod 20 is located above the fixing plate 10 and connected to the bottom end of the fixing frame 30. By rotating the support rod 20, the support rod 20 can move up and down relative to the fixing plate 10 along the Z-axis, thereby driving the fixing frame 30 to move up and down along the Z-axis. One side of the fixing plate 10 has a fixing plate threaded hole 101 communicating with the fixing plate mounting hole. The first fastener 12, such as a screw, is threadedly connected to the fixing plate threaded hole 101, and the end of the first fastener 12 abuts against the support rod 20 to fix the support rod 20 and the fixing plate 10 together. The clamping mechanism 40 is located at the top of the fixed frame 30. The up and down movement of the fixed frame 30 can drive the clamping mechanism 40 to move up and down along the Z-axis, thereby enabling the adjustment of the Z-axis position, i.e., the height position, of the clamping mechanism 40. This can adapt to different working conditions and meet the usage requirements. Specifically, when the height of the clamping mechanism 40 needs to be increased, first tighten the first fastener 12 to separate the end of the first fastener 12 from the support rod 20, then rotate the support rod 20, thereby driving the fixing frame 30 and the clamping mechanism 40 to move upward along the Z-axis. After reaching the predetermined position, tighten the first fastener 12 so that the end of the first fastener 12 abuts against the support rod 20. In this way, the clamping mechanism 40 is increased in height. When the height of the clamping mechanism 40 needs to be decreased, first tighten the first fastener 12 to separate the end of the first fastener 12 from the support rod 20, then rotate the support rod 20, thereby driving the fixing frame 30 and the clamping mechanism 40 to move downward along the Z-axis. After reaching the predetermined position, tighten the first fastener 12 so that the end of the first fastener 12 abuts against the support rod 20. In this way, the clamping mechanism 40 is decreased in height.
[0030] In this embodiment, a mounting hole 301 is provided at the center of the bottom end of the fixing frame 30. The upper end of the support rod 20 is clearance-fitted with the mounting hole 301, allowing the fixing frame 30 to rotate relative to the support rod 20. Two threaded holes are provided on each side of the fixing frame 30, communicating with the mounting hole 301. Two second fasteners 31, such as screws, are threadedly connected to the two threaded holes 301, with the ends of the two second fasteners 31 abutting against the upper end of the support rod 20 to fix the support rod 20 and the fixing frame 30 together. This structure allows for adjustment of the angle of the clamping mechanism 40. Specifically, when it is necessary to adjust the angle of the clamping mechanism 40, first tighten the two second fasteners 31 to separate the ends of the two second fasteners 31 from the upper end of the support rod 20, then rotate the fixing frame 30, which can drive the clamping mechanism 40 to rotate. After reaching the predetermined angle, tighten the two second fasteners 31 to make the ends of the two second fasteners 31 abut against the upper end of the support rod 20. In this way, the angle of the clamping mechanism 40 is adjusted.
[0031] In this embodiment, the upper end of the support rod 20 is provided with a first T-shaped member 21, which is in clearance fit with the mounting hole 301 of the fixing frame, and the ends of the two second fasteners 31 respectively abut against the first T-shaped member 21.
[0032] The first T-shaped part 21 and the support rod 20 are preferably integrally formed, which facilitates manufacturing.
[0033] The clamping mechanism 40 includes two clamping plates 41 and two screws 42, with the two clamping plates 41 and the two screws 42 arranged opposite each other along the X-axis.
[0034] The top of the fixing frame 30 is provided with two support blocks 32, which are arranged opposite each other along the X-axis, forming a clamping cavity between them. The two support blocks 32 and the fixing frame 30 form a U-shaped structure, and preferably, the two support blocks 32 and the fixing frame 30 are integrally formed for ease of manufacturing. Two clamping plates 41 are respectively placed on the top of the fixing frame 30 and located in the clamping cavity, and the fixing frame 30 can support the two clamping plates 41. Two clamping plate mounting holes 411 are respectively provided at the center of the side of the two clamping plates 41 that are far apart. Two screws 42 are respectively threaded to the two support blocks 32. The heads of the two screws 42 are located outside the clamping cavity, and the ends of the two screws 42 are located inside the clamping cavity and are clearance-fitted with the clamping plate mounting holes 411 of the two clamping plates 41. The two screws 42 can rotate relative to the corresponding clamping plates 41, and the rotation of the two screws 42 can drive the two clamping plates 41 to move towards each other or away from each other. The top of the clamping plate 41 is provided with a clamping plate threaded hole communicating with the clamping plate mounting hole 411. Two third fasteners 43, such as screws, are respectively threadedly connected to the clamping plate threaded holes of the two clamping plates 41, and the ends of the two third fasteners 43 respectively abut against the ends of the two screws 42 to fix the clamping plate 41 and the corresponding screws 42 together.
[0035] In practical applications, one end of the electrode is first placed between two clamping plates 41. Then, the third fastener 43 corresponding to one of the clamping plates 41 is screwed to separate the end of the third fastener 43 from the end of the corresponding screw 42. Then, the head of the screw 42 corresponding to one of the clamping plates 41 is rotated so that one of the clamping plates 41 is moved closer to the other clamping plate 41 by the screw 42. Thus, one end of the electrode can be clamped by the two clamping plates 41. In this way, one end of the electrode is clamped by the clamping mechanism 40. Then, the third fastener 43 corresponding to one of the clamping plates 41 is screwed so that the end of the third fastener 43 abuts against the end of the corresponding screw 42, thereby fixing one of the clamping plates 41 and the corresponding screw 42 together. Then, the other end of the electrode is connected to the connecting mechanism of the tensile testing machine. The connecting mechanism is driven by the power mechanism of the tensile testing machine to move away from the three-dimensional four-axis clamping device to apply tension to the electrode. During the application of tension, the tensile testing machine records the displacement and deformation of the electrode. By measuring the displacement of the electrode under the action of tension, the adhesive force of the electrode can be calculated. In this way, the adhesive force of the electrode is tested.
[0036] The clamping mechanism 40, with the aforementioned structure, allows for adjustment of the X-axis position (left or right) of the clamping plate 41, thereby adjusting the clamping position of one end of the electrode sheet. This adapts to different working conditions and meets usage requirements. For example, assuming that in the initial state, the distances from the two clamping plates 41 to the center of the fixing frame 30 are equal, if the clamping position of one end of the electrode sheet needs to be adjusted to the left, first, tighten the third fastener 43 corresponding to the left clamping plate 41 to separate the end of the third fastener 43 from the end of the left screw 42. Then, rotate the head of the left screw 42 to move the left clamping plate 41 to the left along the X-axis direction. After reaching the predetermined position, tighten the third fastener 43 corresponding to the left clamping plate 41 to abut the end of the third fastener 43 against the end of the left screw 42. Then, clamp one end of the electrode sheet... The electrode is placed between two clamping plates 41. Then, the third fastener 43 corresponding to the clamping plate 41 on the right is screwed so that the end of the third fastener 43 is separated from the end of the screw 42 on the right. Then, the head of the screw 42 on the right is rotated so that the clamping plate 41 on the right is moved closer to the clamping plate 41 on the left. Thus, one end of the electrode can be clamped by the two clamping plates 41. Then, the third fastener 43 corresponding to the clamping plate 41 on the right is screwed so that the end of the third fastener 43 abuts against the end of the screw 42 on the right. The position of clamping one end of the electrode is thus adjusted. If the clamping position of one end of the electrode needs to be adjusted to the right, first tighten the third fastener 43 corresponding to the right-side clamping plate 41 to separate the end of the third fastener 43 from the end of the right-side screw 42. Then, rotate the head of the right-side screw 42 to move the right-side clamping plate 41 to the right along the X-axis. After reaching the predetermined position, tighten the third fastener 43 corresponding to the right-side clamping plate 41 so that the end of the third fastener 43 abuts against the end of the right-side screw 42. Then, place one end of the electrode between the two clamping plates 41 and then tighten... Tighten the third fastener 43 corresponding to the left clamp 41 so that the end of the third fastener 43 separates from the end of the left screw 42. Then rotate the head of the left screw 42 so that the left clamp 41 moves closer to the right clamp 41. Thus, one end of the electrode can be clamped by the two clamps 41. Then tighten the third fastener 43 corresponding to the left clamp 41 so that the end of the third fastener 43 abuts against the end of the left screw 42. The position of clamping one end of the electrode is thus adjusted.
[0037] In this embodiment, a support block threaded hole is provided at the center of the support block 32, and two screws 42 pass through the support block threaded holes of the two support blocks 32 respectively and are threadedly connected to the support block threaded holes of the two support blocks 32 respectively.
[0038] The head of the screw 42 is connected to a handle 421. Specifically, the head of the screw 42 has a screw mounting hole, and the handle 421 passes through the screw mounting hole and is fixedly connected to it. The handle 421 facilitates the rotation of the head of the screw 42, making operation convenient.
[0039] In this embodiment, the width of the clamping plate 41 is equal to the width of the fixing frame 30, or the width of the clamping plate 41 can be greater than or equal to the width of the fixing frame 30. The larger the width of the clamping plate 41, the greater its inclusiveness in the Y-axis direction, which allows the position of the electrode in the Y-axis direction to be adjusted, and it can also adapt to electrode sheets of different widths, thus having a wide range of applications.
[0040] The end of the screw 42 is provided with a second T-shaped part 422. The second T-shaped parts 422 of the two screws 42 are respectively clearance-fitted with the clamping plate mounting holes 411 of the two clamping plates 41. The ends of the two third fasteners 43 respectively abut against the second T-shaped parts 422 of the two screws 42.
[0041] The screw 42 and the second T-shaped part 422 are preferably integrally formed, which facilitates manufacturing.
[0042] This utility model is simple to operate, convenient, and highly applicable.
[0043] This utility model also provides a tensile testing machine, including the above-mentioned three-dimensional four-axis clamping device.
[0044] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
