Description

Technical Field

[0001] This utility model relates to the field of pressure testing devices, specifically a pressure testing device for resin balls. Background Technology

[0002] Resin balls, with their advantages of light weight, corrosion resistance, and good insulation, are widely used in toys, bearings, precision instrument cushioning components, sporting goods, and other fields. During the production and application of resin balls, their compressive strength is a key indicator for judging product quality and suitability, requiring testing using a professional compression testing device. Existing compression testing devices have significant shortcomings when testing resin balls: traditional devices often use weights for loading or cylinders for coarse pressure adjustment, failing to achieve precise pressure increase and decrease control, making it difficult to capture subtle deformation data of the resin ball under different pressures. Furthermore, traditional testing devices are mostly simple in structure, only capable of testing under a single pressure, unable to simulate the different pressure scenarios that resin balls might encounter in actual use, resulting in limited reference value for the test results and inaccurate pressure control.

Please see Figure 1 , Figure 2 The pressing assembly 4 includes a servo electric cylinder 41 fixedly installed inside the protective cover 2. The piston inside the servo electric cylinder 41 is equipped with a lifting rod 42. The top of the lifting rod 42 extends to the outer side of the top of the protective cover 2. A support plate 43 is provided at the top end of the lifting rod 42. One end of the support plate 43 extends above the support cylinder 3.

A resin ball is placed inside the arc placement groove 46. A spoke-type pressure sensor 47 is fixedly installed on the top of the lifting rod 42. The support plate 43 is installed on the surface of the spoke-type pressure sensor 47 by bolts.

[0015] In practical use: During the pressing test, the resin ball is placed in the arc-shaped placement slot 46 inside the rotating platform 45. The servo electric cylinder 41 is controlled to descend, and the servo electric cylinder 41 descends, which drives the support plate 43 at the top to follow. The descent of the support plate 43 causes the pressing cover 44 installed at one end of the bottom to contact and press the resin ball. A spoke-type pressure sensor 47 is bolted to the connection between the lifting rod 42 and the support plate 43. When the pressing cover 44 presses on the surface of the resin ball, the spoke-type pressure sensor 47 detects the pressing force of the pressing cover 44, thus accurately feeding back the pressure value on the resin ball. The servo electric cylinder 41 can achieve precise adjustment of pressure from 0-5000N and speed from 0.1-5mm / s, supporting various pressure scenarios such as constant pressure, constant speed, and stepped pressure, providing rich test data for pressing tests and comparisons.

[0016] Please see Figure 3 The rotating assembly 5 includes a reduction motor 51 disposed on one end surface of the support plate 43. An eccentric wheel shaft 52 is fixedly mounted on the output shaft end of the reduction motor 51. One end of the eccentric wheel shaft 52 is fixedly mounted on the top center of the pressing cover 44.

[0017] In practical use: When the reduction motor 51 rotates, it drives the eccentric wheel shaft 52 to rotate. The eccentric wheel shaft 52 drives the pressing cover 44 to rotate. In conjunction with the rotating table 45 mounted on the top of the support cylinder 3, it is convenient to knead the resin ball, so as to realize the pressure bearing capacity of the resin ball under dynamic pressing, and avoid judging the pressure bearing capacity of the resin ball by only the data obtained under static pressing.

[0018] Please see Figure 3 The edge of the geared motor 51 is fixedly connected to several connecting supports 6, and the surface of the connecting supports 6 is threaded with mounting screws 7. The mounting screws 7 are threaded into the threaded holes opened on one end surface of the support plate 43.

[0023] In practical use: The bottom of the test platform 1 is equipped with adjustable support legs 8 to adjust the level of the test platform 1. The bottom of the adjustable support legs 8 is provided with anti-slip rubber protrusions 9 to increase the friction between the adjustable support legs 8 and the placement surface, preventing the test platform 1 from sliding easily.

[0024] Please see Figure 1 The protective cover 2 has heat dissipation holes 10 on its surface.

[0025] In practical use: the heat dissipation holes 10 on the surface of the protective cover 2 facilitate ventilation and heat dissipation for the internal servo electric cylinder 41.

[0026] Please see Figure 2 The test bench 1 is equipped with a control panel 11. The control panel 11 is equipped with a microcontroller display screen 12 and several control buttons 13. The spoke-type pressure sensor 47, servo electric cylinder 41 and geared motor 51 are connected to the control panel 11 through the corresponding control buttons 13. The control panel 11 is electrically connected to an external power supply.

[0027] In practical use: The microcontroller display screen 12 mounted on the surface of the control panel 11 is used to display the pressing pressure value. At the same time, the control buttons 13 are used to control the corresponding servo electric cylinder 41 and the geared motor 51 to work. When the control panel 11 is connected to an external power supply, the control equipment can be operated.

[0028] A resin ball is placed in an arc-shaped placement slot 46 inside the rotating platform 45. The servo electric cylinder 41 is controlled to descend, and the descent of the servo electric cylinder 41 drives the support plate 43 at the top to descend along with the lifting rod 42. The descending support plate 43 causes a pressing cover 44 installed at one end of the bottom to contact and press the resin ball. A spoke-type pressure sensor 47 is bolted to the connection between the lifting rod 42 and the support plate 43. When the pressing cover 44 presses against the surface of the resin ball, the spoke-type pressure sensor 47 detects the pressing force of the pressing cover 44, thus accurately feeding back the pressure value on the resin ball. The servo electric cylinder 41 allows for precise adjustment of pressure from 0-5000N and speed from 0.1-5mm / s, supporting various pressure scenarios such as constant pressure, constant speed, and stepped pressure, providing rich test data for pressing tests and comparisons.
