Specific embodiments

[0021] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] Please refer to Figures 1 to 4 , the present utility model provides a technical solution: a microcomputer servo pressure testing machine, including a testing machine body 1, a test bench 2 is disposed on the testing machine body 1 and an upper pressing plate 3 above the test bench 2, a lower pressing plate 4 capable of moving up and down is disposed on the test bench 2, and the lower pressing plate 4 is fixedly connected to the output shaft of a pressure testing oil cylinder, that is to say, the up and down movement of the lower pressing plate 4 is provided by the pressure testing oil cylinder. This technical solution improves the problems of splashing and hurting people during sample testing and dust pollution in the prior art, and the structures that are not improved adopt the structures in the patent documents mentioned in the background art.

[0023] In this technical solution, a carrier frame 5 is slidably connected to the top of the test bench 2 and is located between the upper pressing plate 3 and the lower pressing plate 4. Specifically, it is preferred that brackets 21 are welded to both sides of the test bench 2 and are close to the other two sides after welding. A guide shaft 211 is welded between the brackets 21 on both sides of the test bench 2. The carrier frame 5 is of a rectangular frame structure, and guide sleeves 51 sleeved on the guide shaft 211 are welded to both sides thereof. A carrier plate 6 is rotatably connected inside the carrier frame 5. When the carrier frame 5 moves horizontally, the carrier plate 6 thereon will pass through the space between the upper pressing plate 3 and the lower pressing plate 4. A placement groove 61 is provided in the middle of the carrier plate 6, and a backing plate 7 is placed in the placement groove 61. The backing plate 7 is used for placing specimens. The backing plate 7 can be directly removed from the placement groove 61. When the carrier frame 5 moves horizontally, the backing plate 7 can carry the specimen through the space between the upper pressing plate 3 and the lower pressing plate 4.

[0024] Furthermore, a relief hole 611 for cooperating with the lower pressing plate 4 is provided at the bottom of the placement groove 61. The cooperation here is a clearance fit. That is to say, when the lower pressing plate 4 moves upward through the relief hole 611, it will abut against the bottom of the backing plate 7, and then can push the backing plate 7 upward, so that the specimen can be squeezed by the backing plate 7 and the upper pressing plate 4 to realize the pressure test of the specimen.

[0025] The top of the carrier frame 5 is connected by a support rod 8 to a protective sleeve 9 located above the carrier plate 6. The height of the top of the protective sleeve 9 is slightly lower than the height of the lower end face of the upper pressing plate 3. This setting facilitates the protective sleeve 9 to pass through the position below the upper pressing plate 3. The setting of the support rod 8 creates a space between the protective sleeve 9 and the carrier frame 5. This space is the space for transferring the specimen onto the backing plate 7. A dust removal suction pipe 101 is fixedly connected to the outer peripheral wall of the protective sleeve 9. During use, the dust removal suction pipe 101 is connected to an external dust removal and filtration system through a fan. The protective sleeve 9 plays a role in preventing sputtering during the pressure test, and the dust removal suction pipe 101 can suck away the dust generated during the test fragmentation to eliminate dust pollution.

[0026] Among them, a buffer rubber sleeve 91 is fixedly sleeved on the protective sleeve 9. The buffer rubber sleeve 91 has the advantages of buffering sputtering and reducing noise.

[0027] In this embodiment, carrier shafts 62 are welded to both sides of the carrier plate 6 and are rotatably connected to both sides inside the carrier frame 5. A limiting platform 71 that is in clearance fit with the placement groove 61 is welded to the bottom of the backing plate 7. The placement groove 61 limits the backing plate 7 through the limiting platform 71. When the carrier plate 6 rotates from the horizontal state to the inclined state, due to the action of the limiting platform 71, the backing plate 7 will not slide off. This setting facilitates pouring out the specimen on the backing plate 7. A positioning hole 73 that is in clearance fit with the lower pressing plate 4 is fixedly provided at the bottom of the backing plate 7. The lower pressing plate 4 can lift the entire backing plate 7 only when it enters the positioning hole 73. This setting enables the backing plate 7 to rise stably after leaving the placement groove 61.

[0028] Further, a positioning groove 72 is formed at the bottom of the backing plate 7 and located outside the limiting platform 71. A magnet 721 magnetically coupled with the bearing plate 6 is nested in the positioning groove 72. Due to the adsorption of the magnet 721, the bonding force between the backing plate 7 and the bearing plate 6 is greatly improved, having the advantage of preventing detachment.

[0029] In this embodiment, a hydraulic cylinder 102 is fixedly connected to one side of the testing machine body 1. A connecting plate 52 is fixedly connected to the bottom of the bearing frame 5 at one end and fixedly connected to the output shaft of the hydraulic cylinder 102. The hydraulic cylinder 102 provides driving force for the translation of the bearing frame 5. A control motor 103 is fixedly connected to one end of the bearing frame 5. The output shaft of the control motor 103 is fixedly connected to one end of the bearing shaft 62. The control motor 103 provides driving force for the rotation of the bearing plate 6.

[0030] In this embodiment, the number of the support rods 8 is two, and the bottoms are respectively welded to the tops of the two longitudinal beams on the bearing frame 5. The support rods 8 are L-shaped, and their free ends are welded to the outer peripheral wall of the protective sleeve 9.

[0031] In this embodiment, the number of the support rods 8 is two, and the bottoms are respectively welded to the tops of the two longitudinal beams on the bearing frame 5. The support rods 8 are L-shaped, and their free ends are welded to the outer peripheral wall of the protective sleeve 9. This setting can increase the space for the specimen to enter and exit the pressure test on the support plate 7.

[0032] Working principle: During use, first, the hydraulic cylinder 102 is used to control the bearing frame 5 to move outside the test bench 2. Then, the specimen is horizontally placed on the backing plate 7 from one side of the bearing plate 6. Then, the bearing frame 5 is controlled to move to the position where the positioning hole 73 is opposite to the lower pressing plate 4. The lower pressing plate 4 is controlled to move upward. After the lower pressing plate 4 contacts the bottom of the backing plate 7, it will lift the backing plate 7. The specimen on the backing plate 7 will approach the upper pressing plate 3 and then be subjected to a pressure test. When the specimen cracks and splashes, the protective sleeve 9 will provide shielding protection. The dust generated during the test will be sucked away by the dust removal and extraction air duct 101. After the test is completed, the bearing frame 5 is controlled to move outside the workbench 2. Then, the control motor 103 is started to control the bearing plate 6 to rotate to an inclined state. At this time, the fragmented specimen on the backing plate 7 will slide down along the inclined plane, and the dust generated by the sliding will also be sucked away by the dust removal and extraction air duct 101 through the protective sleeve 9, eliminating dust pollution.

[0033] In addition, it should be understood that although this specification is described according to embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
