DETAILED DESCRIPTION

[0031] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.

[0032] like Figure 1-Figure 8 As shown, the present invention provides a technical solution: specifically comprising: a detection table 1, a U-shaped frame 2 is arranged on the detection table 1, a cross 3 is arranged on the U-shaped frame 2, each end of the cross 3 is fixedly connected with a pressure head 4 for extrusion detection, and the models of the multiple pressure heads 4 are different, a motor 27 is fixedly connected to the outer wall of the U-shaped frame 2, and the cross 3 is fixedly connected to the driving shaft of the motor 27.

[0033] During specific use, the pressure head 4 rotated to the position below the cross 3 is in use, and the pressure head 4 is used for extrusion detection; the motor 27 drives the cross 3 to rotate, and the pressure head 4 is quickly switched to meet various detection needs.

[0034] A support plate 28 for placing accessories is provided below the U-shaped frame 2. The U-shaped frame 2 and the support plate 28 are arranged correspondingly up and down, and the support plate 28 is fixedly connected to the testing table 1. The operator places the accessories on the testing table 1 and below the U-shaped frame 2.

[0035] An electric cylinder 26 is fixedly connected to the top of the testing platform 1, a slide 25 is fixedly connected to the telescopic end of the electric cylinder 26, a square sleeve 24 is fixedly connected to the side wall of the testing platform 1, the slide 25 is slidably connected to the inside of the square sleeve 24, and the U-shaped frame 2 is fixedly connected to the bottom of the slide 25.

[0036] In actual use, the telescopic end of the electric cylinder 26 is controlled to extend, driving the slide 25 to slide downward inside the square sleeve 24. The slide 25 drives the pressure head 4 to squeeze the accessories through the U-shaped frame 2 and the cross 3, thereby realizing strength testing. The square sleeve 24 and the slide 25 are provided to improve the stability of the structure such as the U-shaped frame 2.

[0037] In order to realize the quick positioning of the accessory, a ring sleeve 5 is arranged outside the U-shaped frame 2, and a connecting rod 6 is fixedly connected to the inner ring of the ring sleeve 5, and one end of the connecting rod 6 away from the ring sleeve 5 is fixedly connected to the U-shaped frame 2. The connecting rod 6 is arranged so that the ring sleeve 5 and the U-shaped frame 2 form a whole.

[0038] The bottom of the ring sleeve 5 is rotatably provided with a ring plate 7, the lower surface of the ring sleeve 5 is provided with a ring groove 22, the inner part of the ring groove 22 is rotatably connected with a swivel 23, the swivel 23 is fixedly connected to the ring plate 7, and an air cavity 8 is formed between the ring sleeve 5 and the ring plate 7. In specific use, a rubber pad can be arranged between the ring sleeve 5 and the ring plate 7 to improve the sealing performance and reduce wear.

[0039] Considering that the cross 3 will be subjected to a large reaction force during the process of the pressure head 4 pressing the accessory, especially when the pressure head 4 is pressed on an inclined surface, the cross 3 will tend to rotate, and the pressure will act on the motor 27. In order to reduce the pressure of the motor 27, a square box 18 is connected to the inner ring of the ring sleeve 5, and a slide column 19 for limiting the cross 3 is provided inside the square box 18. In the present invention, when the pressure head 4 presses the accessory, the slide column 19 slides outward from the inside of the square box 18 and abuts against the right angle of the outside of the cross 3 to limit the cross 3, so that the cross 3 will not rotate, reduce the pressure on the motor 27, and improve the stability of the strength test.

[0040] After the detection is completed, the slide post 19 can be retracted into the interior of the square box 18 without affecting the rotation of the cross 3.

[0041] The bottom of the ring plate 7 is fixedly connected with a cylinder 9, and the cylinder 9 is provided in multiple numbers, and the multiple cylinders 9 are evenly distributed around the ring plate 7. The inside of the cylinder 9 is slidably connected with a slide rod 11, and the slide rod 11 passes through the lower surface of the cylinder 9. The ring plate 7 is provided with a circular hole 10 corresponding to the cylinder 9, and the air cavity 8 is connected with the cylinder 9 through the circular hole 10. Specifically, the cylinder 9 can rotate at the bottom of the ring sleeve 5 through the ring plate 7, and the cylinder 9 and the air cavity 8 can always maintain a connected state.

[0042] A first spring 12 is arranged inside the cylinder 9, and the inner diameter of the circular hole 10 is smaller than that of the cylinder 9, so as to facilitate the arrangement of the first spring 12. One end of the first spring 12 is fixedly connected to the top of the slide bar 11, and the other end of the first spring 12 is fixedly connected to the lower surface of the ring plate 7. When the slide bar 11 slides upward and is recovered inside the cylinder 9, the gas inside the cylinder 9 enters the inside of the air cavity 8 through the circular hole 10, and then enters the inside of the square box 18, pushing the slide post 19 to slide outward to limit the cross 3; and after the test, the reset elastic force of the first spring 12 causes the slide bar 11 to slide downward and reset, and the gas inside the square box 18 flows back from the air cavity 8 and the circular hole 10 to the inside of the cylinder 9, and the slide post 19 is recovered to the inside of the square box 18, which does not affect the rotation of the cross 3.

[0043] A slide plate 13 for fixing accessories is slidably provided at the bottom of the slide bar 11, and the slide plate 13 can slide or rotate at the bottom of the slide bar 11. There is a certain damping sense between the slide plate 13 and the slide bar 11. When an external force is applied, the slide plate 13 can slide or rotate at the bottom of the slide bar 11, and after the external force stops, the position of the slide plate 13 will not change arbitrarily.

[0044] The cylinder 9 can rotate at the bottom of the ring sleeve 5 through the ring plate 7, and drive the slide bar 11 and the slide plate 13 to rotate synchronously. At the same time, the slide plate 13 can slide at the bottom of the slide bar 11 and can also rotate at the bottom of the slide bar 11, so that the position and distribution state of the slide plate 13 can be flexibly adjusted, and the slide bar 11 can slide and shrink inside the cylinder 9, so as to meet the needs of accessories with different shapes and uneven thicknesses.

[0045] During actual use, the operator places the accessory on the testing table 1 and below the U-shaped frame 2; according to the testing needs, the operator selects a suitable type of pressure head 4, and adjusts the position and distribution of the slide plate 13 according to the shape and other characteristics of the accessory, so that the slide plate 13 can abut against the appropriate position of the accessory.

[0046] The telescopic end of the electric cylinder 26 is controlled to extend, driving the slide 25 to slide downward inside the square sleeve 24. The slide 25 drives the pressure head 4 to move downward synchronously through the U-shaped frame 2 and the cross 3. The slide plate 13 first contacts the accessory. As the U-shaped frame 2 and other structures continue to move downward, the slide bar 11 slides upward inside the cylinder 9 and squeezes the first spring 12 to contract. The reset elastic force of the first spring 12 makes the slide plate 13 squeeze and fit on the accessory, completing the adaptive positioning of the accessory, thereby facilitating detection.

[0047] At the same time, when the slide rod 11 slides upward and is recovered inside the cylinder 9, the gas inside the cylinder 9 enters the air cavity 8 through the circular hole 10, and then enters the inside of the square box 18, pushing the slide column 19 to slide outward and abut against the right angle outside the cross 3, limiting the cross 3 and preventing the cross 3 from rotating, thereby reducing the pressure on the motor 27.

[0048] By providing structures such as the ring sleeve 5, the ring plate 7 and the sliding column 19, the adaptive positioning of the accessory is completed during the downward movement of the pressure head 4 for extrusion, which is convenient for operation and reduces the cost of use. At the same time, the sliding column 19 slides outward and abuts against the right angle of the outside of the cross 3 to limit the cross 3, prevent the cross 3 from rotating, and improve the efficiency of detection.

[0049] After the detection is completed, the telescopic end of the electric cylinder 26 is controlled to be retracted, driving the slide 25 to slide upward inside the square sleeve 24, and the slide 25 drives the pressure head 4 to move upward synchronously through the U-shaped frame 2 and the cross 3, and the slide plate 13 is out of contact with the attachment; the reset elastic force of the first spring 12 causes the slide rod 11 to slide downward and reset, and the gas inside the square box 18 flows back to the inside of the cylinder 9 through the air cavity 8 and the circular hole 10, and the slide column 19 is retracted to the inside of the square box 18 without affecting the rotation of the cross 3.

[0050] A protrusion 20 is fixedly connected to the inner wall of the square box 18, and a third spring 21 is arranged inside the square box 18, one end of the third spring 21 is fixedly connected to the protrusion 20, and the other end of the third spring 21 is fixedly connected to the slide post 19. When the slide post 19 slides outward from the inside of the square box 18, the slide post 19 stretches the third spring 21; after the detection is completed, the return elastic force of the third spring 21 can make the slide post 19 quickly return to its original position.

[0051] The lower surface of the slide plate 13 is fixedly connected to a limiting block 14 , and the limiting block 14 is provided to increase the friction force of the lower surface of the slide plate 13 to avoid slipping.

[0052] In order to prevent the ring plate 7 from rotating at will at the bottom of the ring sleeve 5 during the detection process, a vertical groove 17 is provided on the upper surface of the slide bar 11, and a vertical rod 15 is slidably provided inside the vertical groove 17. The vertical rod 15 passes through the circular hole 10 and abuts against the top of the ring sleeve 5, and the first spring 12 surrounds the outside of the vertical rod 15. The outer diameter of the vertical rod 15 is smaller than the inner diameter of the circular hole 10. When the vertical rod 15 passes through the inside of the circular hole 10, it does not affect the communication between the air cavity 8 and the cylinder 9 through the circular hole 10. A second spring 16 is provided inside the vertical groove 17, one end of the second spring 16 is fixedly connected to the bottom of the vertical groove 17, and the other end of the second spring 16 is fixedly connected to the vertical rod 15.

[0053] Specifically, by providing structures such as the vertical rod 15 and the second spring 16, when the slide rod 11 slides upward and is recovered inside the cylinder 9, the vertical rod 15 is driven to pass through the circular hole 10, and the vertical rod 15 abuts against the inner wall of the top end of the ring sleeve 5; as the slide rod 11 continues to slide upward inside the cylinder 9, the vertical rod 15 will be recovered to the inside of the vertical groove 17 and squeeze the second spring 16 to shrink, and the restoring elastic force of the second spring 16 makes the vertical rod 15 tightly abut against the inner wall of the top end of the ring sleeve 5, so that the ring plate 7 will not rotate arbitrarily at the bottom of the ring sleeve 5 during the detection process, thereby improving the stability of the accessory positioning and ensuring the efficiency of the detection.

[0054] Working principle: The operator places the accessory on the test bench 1 and below the U-shaped frame 2; according to the test requirements, the operator selects a suitable type of pressure head 4, and adjusts the position and distribution of the slide plate 13 according to the shape and other characteristics of the accessory, so that the slide plate 13 can abut against the appropriate position of the accessory.

[0055] The telescopic end of the electric cylinder 26 is controlled to extend, driving the slide 25 to slide downward inside the square sleeve 24. The slide 25 drives the pressure head 4 to move downward synchronously through the U-shaped frame 2 and the cross 3. The slide plate 13 first contacts the accessory. As the U-shaped frame 2 and other structures continue to move downward, the slide bar 11 slides upward inside the cylinder 9 and squeezes the first spring 12 to contract. The reset elastic force of the first spring 12 makes the slide plate 13 squeeze and fit on the accessory, completing the adaptive positioning of the accessory, thereby facilitating detection.

[0056] At the same time, when the slide rod 11 slides upward and is recovered inside the cylinder 9, the gas inside the cylinder 9 enters the air cavity 8 through the circular hole 10, and then enters the inside of the square box 18, pushing the slide column 19 to slide outward and abut against the right angle outside the cross 3, limiting the cross 3 and preventing the cross 3 from rotating, thereby reducing the pressure on the motor 27.

[0057] After the detection is completed, the telescopic end of the electric cylinder 26 is controlled to be retracted, driving the slide 25 to slide upward inside the square sleeve 24, and the slide 25 drives the pressure head 4 to move upward synchronously through the U-shaped frame 2 and the cross 3, and the slide plate 13 is out of contact with the attachment; the reset elastic force of the first spring 12 causes the slide rod 11 to slide downward and reset, and the gas inside the square box 18 flows back to the inside of the cylinder 9 through the air cavity 8 and the circular hole 10, and the slide column 19 is retracted to the inside of the square box 18 without affecting the rotation of the cross 3.

[0058] When the slide bar 11 slides upward and is recovered inside the cylinder 9, it drives the vertical rod 15 to pass through the circular hole 10, and the vertical rod 15 abuts against the inner wall of the top end of the ring sleeve 5; as the slide bar 11 continues to slide upward inside the cylinder 9, the vertical rod 15 will be recovered into the vertical groove 17 and squeeze the second spring 16 to contract. The restoring elastic force of the second spring 16 makes the vertical rod 15 tightly abut against the inner wall of the top end of the ring sleeve 5, so that the ring plate 7 will not rotate at will at the bottom of the ring sleeve 5 during the detection process.

[0059] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention.
