Description

Technical Field

[0001] This utility model relates to the field of automatic feeding technology for cement test blocks, and in particular to an automatic feeding mechanism for compression test blocks. Background Technology

[0002] A cement compression tester can perform compressive strength tests on cement test blocks. Traditionally, the steps for performing compressive strength tests on cement test blocks using a cement compression tester are as follows: "First, the cement test block is broken using a flexural tester. Then, one of the cement test blocks is manually placed into the compression tester for compressive strength testing. After the compression test is completed, the compression tester is cleaned. After cleaning, the remaining cement test block is manually placed into the compression tester for compressive strength testing. After the test is completed, the compression tester is cleaned again."

[0003] Traditional compressive strength testing relies too heavily on manual labor and lacks automation. To improve the automation level of cement block compressive strength testing, a serial operation mode of "grabbing-positioning-cleaning" is currently being adopted, similar to that of industrial robots. An industrial robot grips a cement block and places it into the cavity of the cement compression tester with a positioning accuracy of ±0.1mm. After the compressive strength test is completed, the robot's end gripper automatically replaces itself with a cleaning mechanism to quickly remove fragments from the cavity. Subsequently, the robot automatically replaces its gripper again and grips a second cement block for compressive strength testing.

[0004] However, the automated operation of the above-mentioned cement block compressive strength test has the following problems: First, it is time-consuming. Each step of the industrial robot's "grabbing-positioning-cleaning" can only be performed individually, which wastes a lot of time when conducting batch compressive strength tests on cement blocks. Second, the degree of automation is low. The industrial robot needs to frequently replace the gripper and pick up new cement blocks to conduct compressive strength tests, making the whole process cumbersome and not intelligent enough.

[0005] Based on this, an automatic feeding mechanism for test blocks of a compression tester is provided. Utility Model Content

Both sides of the brush holder are connected to one side of the guide rod.

[0012] As a preferred embodiment of this utility model, the pushing mechanism includes a pushing plate, a rodless cylinder mounting plate, a rodless cylinder, a support plate, and a fixing plate.

[0031] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0032] like Figures 1-9 As shown, an automatic feeding mechanism for cement test blocks includes a positioning mechanism 1, which is fixedly installed at one end of a base 5 and has a positioning cavity 11 for accommodating cement test blocks 7; a transfer mechanism 2, which is fixedly installed at the other end of the base 5 and located at the front end of the positioning mechanism 1, and has a transfer mechanism 21 capable of carrying at least two cement test blocks 7 and a cleaning mechanism 22 for cleaning cement fragments; a pushing mechanism 3, which is fixedly installed on a fixed column 6 and has a pushing plate 31 capable of pushing the cement test blocks 7; and a lifting mechanism. 4. The lifting mechanism 4 is fixedly installed at the rear end of the pushing mechanism 3. The lifting mechanism 4 has a lifting storage plate 41 that can support a cement test block 7. Two cement test blocks 7 are placed in the transfer mechanism 21. Under the action of the pushing plate 31, the first cement test block 7 is located on the lifting storage plate 41 and is lifted upward under the action of the lifting mechanism 4. The second cement test block 7 enters the positioning cavity 11 and undergoes a compressive strength test. After the compressive strength test of the second cement test block 7 is completed, it is cleaned by the cleaning mechanism 22. Subsequently, the first cement test block 7 enters the positioning cavity 11 under the action of the lifting mechanism 4 to undergo a compressive strength test.

[0033] In this invention, after the compressive strength test of the next cement block 7 is completed and the sample is cleaned, the first cement block 7 can be placed into the positioning cavity 11 by the lifting mechanism 4. Compared with the traditional gripper grabbing the new cement block 7 again, it saves the time of gripper back and forth and gripper replacement, making the batch compressive strength test of cement blocks 7 faster.

[0034] After one cement test block 7 has completed its compressive strength test and been cleaned, the other cement test block 7 immediately enters the positioning cavity 11 for a compressive strength test. Compared with the prior art, two cement test blocks 7 can be placed at a time, eliminating the need to frequently replace the grippers and go to a fixed location to grab new cement test blocks 7 for compressive strength testing. This reduces the number of robot operations, increases automation and intelligence, saves time, and facilitates the batch compressive strength testing of cement test blocks 7.

[0035] Further refine the specific structures of positioning mechanism 1, shifting mechanism 2, pushing mechanism 3, and lifting mechanism 4 to facilitate understanding of the automatic feeding process of cement test blocks 7.

[0036] like Figure 4 As shown, the positioning mechanism 1 includes a support column 12, a pressure mold 13, a positioning plate 14, and a second photoelectric sensor 15. The support column 12 is fixed on the base 5, and the pressure mold 13 is fixed on the support column 12. The pressure mold 13 forms a positioning cavity 11 to accommodate the cement test block 7. The positioning plate 14 is installed on one side of the positioning cavity 11, and the second photoelectric sensor 15 is provided on the positioning plate 14.

[0037] The positioning mechanism 1 includes a cylinder mounting base 16, a positioning cylinder 17, and a clamping block 18. The positioning cylinder 17 is fixedly mounted on the support column 12 via the cylinder mounting base 16. At least two clamping blocks 18 are fixedly mounted at the front end of the positioning cylinder 17. The positioning cylinder 17 is positioned opposite to the positioning plate 14. The clamping blocks 18 cooperate with the positioning plate 14 to position the cement test block 7 inside the positioning cavity 11.

[0038] Among them, the clamping block 18 is Z-shaped. After the cylinder rod of the positioning cylinder 17 extends, the clamping block 18 can abut against the side of the cement test block 7 and drive the cement test block 7 to move closer to the positioning plate 14. The clamping block 18, together with the positioning plate 14, realizes the positioning of the cement test block 7, which facilitates the pressure mold 13 to perform compressive strength test on the cement test block 7.

[0039] Specifically, the second photoelectric sensor 15 detects that the cement block 7 is located in the positioning cavity 11 of the pressure mold 13 and sends an electrical signal to the control component. The control component controls the movement of the positioning cylinder 17. The cylinder rod of the positioning cylinder 17 extends and drives the clamping block 18 to move towards the positioning plate 14, thereby positioning the cement block 7 in the designated position. Subsequently, the cylinder rod of the positioning cylinder 17 retracts and drives the clamping block 18 to reset. The pressure mold 13 performs a compressive strength test on the positioned cement block 7.

[0040] like Figures 5-6 As shown, the transfer mechanism 21 includes a support 211, a cylinder mounting plate 212, a transfer cylinder 213, a transfer guide rail slider assembly 214, a guide rail connecting plate 215, a transfer bearing plate 216, and a first photoelectric sensor 217. The support 211 is fixedly mounted on the base 5. The transfer guide rail slider assembly 214 is mounted on the top of the support 211. The transfer cylinder 213 is fixedly mounted on one side of the support 211 via the cylinder mounting plate 212. The guide rail connecting plate 215 is fixedly mounted on the slider of the transfer guide rail slider assembly 214. The cylinder rod of the transfer cylinder 213 is connected to one side of the guide rail connecting plate 215. The transfer bearing plate 216 is fixedly mounted on the top of the guide rail connecting plate 215. The first photoelectric sensor 217 is disposed between the guide rail connecting plate 215 and the transfer bearing plate 216.

[0041] The cleaning mechanism 22 includes a mounting block 221, a cleaning cylinder 222, a guide rod 223, and a brush holder 224. The mounting block 221 is fixedly mounted on the guide rail connecting plate 215. The cleaning cylinder 222 is fixedly mounted in the middle of the mounting block 221. One guide rod 223 is movably mounted on each side of the mounting block 221. The cylinder rod of the cleaning cylinder 222 is fixed in the middle of the brush holder 224. Both sides of the brush holder 224 are connected to one side of the guide rod 223.

[0042] The transfer bearing plate 216 has a circular hole, and the first photoelectric sensor 217 located below the transfer bearing plate 216 can detect whether a cement test block 7 is placed on the transfer bearing plate 216 through the circular hole.

[0043] The brush holder 224 contains a brush.

[0044] Specifically, the first photoelectric sensor 217 is used to detect whether there is a cement test block 7 on the transfer bearing plate 216. Any cement test block 7 on the transfer bearing plate 216 will subsequently undergo a compressive strength test in the positioning mechanism 1. After the compressive strength test is completed, the cylinder rod of the transfer cylinder 213 extends, and the slider of the transfer guide rail slider assembly 214 drives the guide rail connecting plate 215 to move. The cleaning mechanism 22, which is fixed on the guide rail connecting plate 215, is located at the front end of the positioning mechanism 1. The cylinder rod of the cleaning cylinder 222 in the cleaning mechanism 22 extends, and the brush holder 224 enters the positioning cavity 11 under the action of the guide rod 223 to clean the cement fragments in the positioning cavity 11. Furthermore, the cylinder rod of the cleaning cylinder 222 in the cleaning mechanism 22 extends and retracts multiple times to achieve multiple cleaning of the cement fragments in the positioning cavity 11, ensuring that the inside of the positioning cavity 11 is clean.

[0045] The pushing mechanism 3 includes a pushing plate 31, a rodless cylinder mounting plate 32, a rodless cylinder 33, a support plate 34, and a fixing plate 35. The rodless cylinder 33 is fixedly mounted on the top end of the rodless cylinder mounting plate 32. The pushing plate 31 is mounted on the slide of the rodless cylinder 33. The bottom end of the rodless cylinder mounting plate 32 is connected to the fixing plate 35 through the support plate 34. The fixing plate 35 is fixedly mounted on the front end of the base 5.

[0046] The rodless cylinder mounting plate 32 is connected to the base 5 through the support plate 34 and the fixing plate 35, and is also connected to the fixing column 6 through other parts, which ensures the stability of the rodless cylinder mounting plate 32 installation, and thus ensures the stability of the movement of the push plate 31 indirectly located on the rodless cylinder mounting plate 32.

[0047] Specifically, when the push plate 31 is not pushed, it can limit the cement test block 7 placed on the transfer bearing plate 216. When the slide of the rodless cylinder 33 is activated, the push plate 31 is pushed, the first cement test block 7 enters the lifting mechanism 4, and the second cement test block 7 enters the positioning cavity 11, in preparation for the subsequent compressive strength test.

[0048] The lifting mechanism 4 includes a lifting storage plate 41, a connecting block 42, a lifting cylinder 43, a slide connecting plate 44, and a third photoelectric sensor 45. One end of the connecting block 42 is fixedly installed on the top of the rodless cylinder mounting plate 32 away from the rodless cylinder 33. The other end of the connecting block 42 is provided with the lifting cylinder 43. The cylinder rod of the lifting cylinder 43 is connected to the lifting storage plate 41 through the slide connecting plate 44. The third photoelectric sensor 45 is also fixedly installed on one end of the lifting storage plate 41.

[0049] The lifting cylinder 43 is tilted and fixed on the connecting block 42 to avoid interference between its vertical fixation and the positioning mechanism 1, and the lifting storage plate 41 is horizontally set.

[0050] The lifting mechanism 4 includes a cement baffle 46, a pushing cylinder 47, a pushing slide rail slider assembly 48, and a cement pushing plate 49. The cement baffle 46 is fixedly installed on the side of the lifting storage plate 41 away from the slide connecting plate 44. The pushing slide rail slider assembly 48 is installed on the outer wall of the cement baffle 46, and the cement pushing plate 49 is installed on the pushing slide rail slider assembly 48. The pushing cylinder 47 is also installed on the outer wall of the cement baffle 46, and the cylinder rod of the pushing cylinder 47 is fixedly connected to the cement pushing plate 49.

[0051] The lifting storage plate 41, the sliding table connecting plate 44, and the cement baffle 46 are used to position the previous cement test block 7. Several reinforcements can be added between the sliding table connecting plate 44 and the cement baffle 46 to enhance the connection strength between them and ensure the strength and stability of the lifting mechanism 4.

[0052] Specifically, the first cement block 7 enters the lifting storage plate 41 under the action of the push plate 31. After the third photoelectric sensor 45 detects the first cement block 7, it sends an electrical signal to the control component. The control component controls the cylinder rod of the lifting cylinder 43 to retract, and the first cement block 7 is lifted on the lifting storage plate 41, thus not affecting the compressive strength test of the second cement block 7. Furthermore, after the compressive strength test of the second cement block 7 is completed and the inside of the positioning cavity 11 is cleaned by the cleaning mechanism 22, the control component controls the cylinder rod of the lifting cylinder 43 to extend. The first cement block 7 is located at the rear end of the positioning cavity 11. Further, the cylinder rod of the push cylinder 47 retracts, and the cement push plate 49 pushes the first cement block 7 into the positioning cavity 11, where the compressive strength test is completed inside the positioning mechanism 1.

[0053] A fragment guide groove 8 is fixed on the side of the base 5 away from the transfer mechanism 21 and the cleaning mechanism 22. The fragment guide groove 8 is used to guide the fragments into the fragment collection box.

[0054] This invention first uses a transfer mechanism 21 and a pushing mechanism 3 to grasp and transport the two cement test blocks 7. Then, the positioning mechanism 1 and the lifting mechanism 4 automatically separate and position the two cement test blocks 7. Subsequently, after one of the cement test blocks 7 completes the compressive strength test, the cleaning mechanism 22 immediately removes the gravel. Furthermore, the other cement test block 7 is automatically replaced by the lifting mechanism 4 and its compressive strength is tested. The whole process is more continuous and more efficient.

[0055] Each component of this invention is equipped with a photoelectric sensor, enabling monitoring of the cement test block 7 within each component.

[0056] Ensure the feasibility of automatic feeding of cement test blocks 7.

[0057] Specifically, an automatic feeding mechanism for test blocks in a compression testing machine is implemented:

[0058] Step 1: Place two cement test blocks 7 into the transfer bearing plate 216. The first photoelectric sensor 217 detects the cement test block 7 and transmits an electrical signal to the control component. The control component controls the rodless cylinder 33 to move. The rodless cylinder 33 controls the pusher plate 31 to push the two cement test blocks 7. The third photoelectric sensor 45 detects that the first cement test block 7 has been placed in place and transmits an electrical signal to the control component. The control component controls the rodless cylinder 33 to return to its original position.

[0059] Step 2: The control components control the lifting cylinder 43 to retract the cylinder rod, and the previous cement test block 7 is moved out of the area covered by the pressure mold 13;

[0060] Step 3: The second photoelectric sensor 15 detects the next cement test block 7 and transmits an electrical signal to the control component. The control component controls the cylinder rod of the positioning cylinder 17 to extend and position the next cement test block 7 through the positioning plate 14 and the clamping block 18. After positioning is completed, the cylinder rod of the positioning cylinder 17 retracts and the pressure mold 13 performs a compressive strength test on the next cement test block 7 located in the positioning cavity 11.

[0061] Step 4: After the compressive strength test is completed, the cylinder rod of the transfer cylinder 213 extends, the cleaning mechanism 22 is located at the front end of the positioning mechanism 1, the cylinder rod of the cleaning cylinder 222 extends to drive the brush holder 224 to clean the positioning cavity 11, and after cleaning is completed, the cylinder rod of the cleaning cylinder 222 retracts.

[0062] Step 5: The cylinder rod of lifting cylinder 43 extends, placing the previous cement test block 7 at the rear end of positioning cavity 11. The cylinder rod of pushing cylinder 47 retracts, pushing the previous cement test block 7 into positioning cavity 11. After the second photoelectric sensor 15 detects the previous cement test block 7, the cylinder rod of positioning cylinder 17 extends again. After the previous cement test block 7 is positioned by the positioning plate 14 and the clamping block 18, the cylinder rod of positioning cylinder 17 retracts again. The pressure mold 13 performs a compressive strength test on the previous cement test block 7 located in positioning cavity 11.

[0063] Step Six: Repeat Step Four;

[0064] The compressive strength test was completed on two cement specimens 7.
