[0005] The purpose of the utility model is to solve the shortcomings of the prior art and to propose an engineering plastic impact strength testing device with good stability.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A device for detecting the impact strength of engineering plastics with good stability comprises a support base, a vertical bracket fixedly connected to the middle of the rear end of the support base, a hydraulic rod 2 fixedly connected to the upper rear end of the vertical bracket, a movable groove provided on the upper part of the vertical bracket, a movable frame movably connected in the groove of the movable groove, a reserved hole of the movable frame fixedly connected to the output end of the hydraulic rod 2, a connecting frame fixedly connected to the front of the connecting frame, a fixed frame fixedly connected to the front of the fixing frame, sliding grooves provided at both ends of the fixing frame, a sliding frame movably connected in the groove of the sliding groove.

The pressing plate is fixed by the left and right groups of positioning frames. Because the positioning frames are connected to the adjustment frame and the sliding frame in sequence, the positioning frames are adjusted horizontally and stably under the fixed frame. The distance between the left and right groups of positioning frames can be adjusted according to the specifications of the pressing plate, thereby facilitating the stable assembly of the pressing plate.

First, the output end of the hydraulic rod 24 is connected to the movable frame 8 to control the lifting of the stamping mechanism, and the pressing plate 16 is installed under the fixed frame 6. The pressing plate 16 is fixed by the left and right two sets of positioning frames 15. Because the positioning frames 15 are connected to the adjusting frame 14 and the sliding frame 13 in turn, the positioning frames 15 are adjusted horizontally and stably under the fixed frame 6. The spacing between the left and right groups of positioning frames 15 can be adjusted according to the specifications of the pressing plate 16, so as to facilitate the stable assembly of the pressing plate 16. The pressing plate 16 can be adjusted accordingly according to the specifications of the engineering plastics to be tested, and then the pressing plate 16 is used to perform pressure strength testing on the plastic plate.

[0034] Specifically, the front of the sliding frame 13 is fixedly connected to the adjusting frame 14, the upper center thread of the adjusting frame 14 is connected to the adjusting bolt 12, and the adjusting bolt 12 is fixedly connected to the servo motor 11 at one end of the adjusting frame 14. The sliding frame 13, the adjusting frame 14 and the positioning frame 15 are combined. The adjusting bolt 12 can control the horizontal stable adjustment, and the servo motor 11 can control the steering of the adjusting bolt 12, so that the position of pressure plates 16 of different specifications can be fixed.

[0035] Specifically, the adjusting frame 14 is fixedly connected to a positioning frame 15 at one end of the sliding frame 13, and the positioning frame 15 is movably connected to a pressure plate 16 at one end of the adjusting frame 14. The positioning frame 15 is adjusted to be horizontal and stable under the fixed frame 6. The spacing between the left and right groups of positioning frames 15 can be adjusted according to the specifications of the pressure plate 16, so as to facilitate the stable assembly of the pressure plate 16. The pressure plate 16 can be adjusted accordingly according to the specifications of the tested engineering plastics to ensure that the pressure plate 16 can effectively stamp the engineering plastics below.

[0036] Specifically, the rear end of the support base 1 is fixedly connected to a hydraulic rod 2, and the output end of the hydraulic rod 2 is fixedly connected to a connecting frame 20. The support base 1 serves to support and stabilize the entire device, and the hydraulic rod 2 is arranged on both sides of the rear end of the support base 1, and can control the horizontal movement of the corresponding connecting frame 20 respectively.

[0037] Specifically, the front of the connecting frame 20 is fixedly connected to the driving frame 19, and the driving frame 19 is movably connected to the inner cavity of the support base 1 at one end of the connecting frame 20. The movement direction of the driving frame 19 in the inner cavity of the support base 1 depends on the connecting frame 20, which plays a vital role in the subsequent horizontal movement direction of the upper support frame 17 of the support base 1.

[0038] Specifically, the top of the driving frame 19 is fixedly connected to the traction frame 18, and the top of the support base 1 is provided with a traction groove 7. The outer wall of the traction frame 18 is movably connected to the groove of the traction groove 7.

The support frame 17 moves synchronously with the driving frame 19, thereby controlling the spacing between the left and right groups of support frames 17, which can be adjusted according to the size of the engineering plastic. The engineering plastic is firmly and stably positioned, so that the plastic plate can fully demonstrate its compressive strength performance, avoiding the support frame 17 and the support base 1 being too close, which will cause the plastic plate to be bent and lifted by the support base 1, thereby failing to accurately detect the maximum pressure that the plastic plate can withstand.

[0039] Specifically, the top of the traction frame 18 is fixedly connected to the support frame 17, and the support frame 17 is movably connected to the top of the support base 1 at one end of the traction frame 18. The engineering plastic is firmly and stably positioned, so that the plastic plate can fully demonstrate its compressive strength performance.

[0040] Specifically, the support frame 17 is positioned below the positioning frame 15, and the top of the pressure plate 16 is movably connected to the bottom of the fixing frame 6. The component position design is clear and reasonable, which can effectively impact the engineering plastic and can intuitively observe the changes in the pressure of the plastic plate.

[0041] Working principle: Hydraulic rod 12 is arranged on both sides of the rear end of the support base 1, and can control the horizontal movement of the corresponding connecting frame 20 respectively. The moving direction of the driving frame 19 in the inner cavity of the support base 1 depends on the moving direction of the connecting frame 20, and the traction frame 18 is arranged in the traction groove 7, which serves the purpose of series connection. The support frame 17 moves synchronously with the driving frame 19, so the hydraulic rod 12 can control the spacing between the support frames 17 arranged at the left and right ends of the upper part of the support base 1, and the support frame 17 can effectively position the engineering plastic. The subsequent pressing plate 16 is arranged and installed under the fixed frame 6, and the pressing plate 16 is fixed by the left and right groups of positioning frames 15. Because the positioning frame 15 is connected to the adjusting frame 14 and the sliding frame 13 in turn, the positioning frame 15 is adjusted to be horizontal and stable under the fixed frame 6, and the spacing between the left and right groups of positioning frames 15 can be adjusted according to the specifications of the pressing plate 16, so as to facilitate the assembly and stability of the pressing plate 16. The output end of the hydraulic rod 24 is connected to the movable frame 8 to control the lifting and lowering of the pressing plate 16, thereby realizing the pressing plate 16 to punch the engineering plastic.
