[0019] The technical scheme of the utility model will be further illustrated in the following in combination with the drawings and specific embodiments.
[0020] As Figs. 1 to 3As shown, the present embodiment provides a point and line tester fixture, mainly used for the problem that the special-shaped workpiece cannot be effectively clamped during the test process, and the existing fixture cannot accurately control the clamping force, and the existing fixture lacks a flexible protective layer and a damping device, which is easy to damage the workpiece with soft or fragile material during clamping. The specific structure is as follows: including clamp base 1, workbench surface 2, transverse moving cylinder 3, longitudinal moving cylinder 4, push plate 5, fixed baffle 6, guide rail 7, sliding device 8. The clamp base 1 is the supporting foundation of the whole fixture, and is stable for the overall structure. The workbench surface 2 is fixedly installed on the clamp base 1, and provides an operation platform for the workpiece to be tested; the guide rail 7 is fixedly installed on the clamp base 1 by a bolt fastener, the sliding device 8 is slidably connected with the guide rail 7 through a sliding block, and the sliding device 8 is freely movable relative to the clamp base 1 along the guide rail 7. The transverse moving cylinder 3 and the longitudinal moving cylinder 4 are respectively installed on the sliding device 8, and are arranged perpendicular to each other, and the driving shafts of the cylinders are connected with the push plate 5 through connecting pieces at the front ends, so as to drive the push plate 5 in horizontal and vertical directions. The push plate 5 can be flexibly adjusted according to the size and shape of the workpiece. After the push plate 5 is adjusted in the transverse and longitudinal directions, the clamping force is accurately applied to the workpiece through the cylinder control.
[0021] Further, in order to ensure that the sliding device 8 can be stably fixed after being adjusted, the locking device 9 is arranged on the sliding device 8 in the present embodiment. The locking device 9 can be an electric locking device or a manual locking device. In the present embodiment, the electric locking is selected for the locking device 9. The electric locking can be locked through a button or remote control, and the locking force can be accurately controlled, and full automatic control can be realized. Alternatively, the manual locking is selected for the locking device 9. The manual locking can be directly controlled by manpower to lock and unlock, and can be flexibly used. Both of them can achieve the locking effect of the sliding device, and can be selected according to the actual situation. After the position of the sliding device is adjusted, the user starts the locking device to ensure that the transverse and longitudinal moving cylinders will not move positions due to vibration or external force during the test process, and the clamping accuracy of the workpiece is ensured.
[0022] Further, in order to avoid the impact force or vibration generated during the clamping of the cylinder from affecting the positioning accuracy of the workpiece, the damping pad 10 is arranged at the connection between the transverse moving cylinder 3 and the longitudinal moving cylinder 4 and the push plate 5. The damping pad 10 can effectively absorb the vibration generated during clamping, and ensure the stability of the workpiece when being clamped, thereby improving the accuracy and consistency of the test.
[0023] Further, in order to better protect the workpiece, especially the surface of the special-shaped workpiece from damage caused by clamping force, the surface of the push plate 5 and the fixed baffle 6 is covered with an elastic layer 11 made of rubber or other flexible materials, which can buffer the direct pressure generated by the push plate 5 and the fixed baffle 6 when clamping the workpiece, effectively avoiding damage to the surface of the workpiece.
[0024] Further, in order to achieve precise control of the position of the sliding device 8, a position detection sensor 12 is installed on the sliding device 8, which can monitor the position of the sliding device 8 in real time and transmit the position signal to the control unit, facilitating the user to accurately adjust the position of the workpiece.
[0025] Further, in order to control the size of the clamping force, a pressure detection sensor 13 is provided on the push plate 5 and the fixed baffle 6, which can detect the pressure applied to the workpiece during clamping in real time and feed back the detection signal to the control unit. Through the control unit, the clamping force of the horizontal moving cylinder 3 and the vertical moving cylinder 4 can be automatically adjusted to ensure that the workpiece will not be deformed or damaged due to excessive clamping force.
[0026] Further, the embodiment also includes a control unit electrically connected with the horizontal moving cylinder 3, the vertical moving cylinder 4, the position detection sensor 12 and the pressure detection sensor 13. The user can accurately control the action of the entire jig through the control unit, including adjusting the position of the push plate 5, the clamping force and monitoring the clamping state of the workpiece. The control unit can not only realize manual operation, but also can set automatic control program to adapt to different types of workpieces and different test requirements.
[0027] Working principle:
[0028] In use, first place the workpiece to be tested on the workbench 2. At this time, the horizontal moving cylinder 3 and the vertical moving cylinder 4 work together through the control system to control the sliding device 7, realizing the accurate movement of the push plate 5 in the two-dimensional plane, so that the push plate 5 accurately translates towards the fixed baffle 6. After the push plate 5 contacts the workpiece, a certain force is continuously applied to firmly position the workpiece on the workbench 2, and the fixed baffle 6 plays an important supporting role. The locking device 8 added in the sliding device 7 can be conveniently locked in the current position by manual or automatic mode. In repeated tests, the position of the locking device 8 is adjusted according to the real-time feedback of the position detection sensor 12, and the pressure applied to the sample is dynamically adjusted according to the data provided by the pressure detection sensor 13, so that each test is completed under ideal working conditions. Not only improves the production efficiency, but also ensures the processing quality consistency and process repeatability of the product.
