Description

Technical Field

[0001] The invention relates to the technical field of laboratory hardness testing, and in particular to a laboratory hardness testing device. Background Art

[0002] The laboratory is specially used to conduct various tests on the products submitted for inspection. The data from various tests are used to determine whether the samples submitted for inspection are qualified, and then to determine whether the products in the same batch are qualified. When testing samples with special requirements, the hardness of the samples will be tested.

[0003] The search found:

[0004] Patent 1: A hardness tester with publication number CN209656476U. When testing the hardness of a sample, first place the sample on the workpiece table, start the cylinder to make the sample at a suitable height, then step on the pedal with your foot, the vertical rod moves downward, the angle of the connecting rod changes and pushes the rotating rod outward, the rotating rod rotates to clamp the sample, and then turn the wheel to rotate the screw to lower the measuring instrument and apply a certain pressure to the sample to measure the hardness value of the sample.

[0005] Patent 2: A hardness testing machine with publication number CN211718018U. Before the hardness test is required, the two ends of the material sample are placed on the upper surface of the lower clamping plates of the left and right clamps. By driving the third telescopic rod to extend, the upper clamping plate of the clamp is in contact with the upper surface of the material sample to achieve reliable clamping and fixation of the material sample. The second telescopic rod is extended and shortened by the left and right second hydraulic cylinders to adjust the positions of the left and right clamps to accommodate material samples of different sizes. After the material sample is clamped, the first telescopic rod is extended by the first hydraulic cylinder until the hardness test head contacts the surface of the material sample and a load is applied. The pressure sensor arranged at the lower end of the hardness test head can sense the magnitude of the load applied to the material sample.

[0006] The applicant found that the above patent has deficiencies in actual use:

[0007] For example, the two rotating rods in Patent 1 maintain the same speed and move relative to each other or towards each other during the actual movement. Therefore, when the placed sample is of irregular shape, one of the two rotating rods will first contact the sample while the two rotating rods move relative to each other at the same speed, and push the sample to move to contact the other rotating rod, thus causing the sample to move on the workpiece table, resulting in a deviation between the sample test point and the measuring instrument.

[0008] The lower clamps of the two clamps in Patent 2 are located on the same horizontal line. Therefore, when facing irregular material samples, it is easy for one end of the material sample to fail to contact one of the lower clamps, or both lower clamps cannot contact the corresponding lower clamps. Therefore, when the upper clamp is lowered to rest against both sides of the material sample, it is easy to cause both sides of the material sample to collapse.

[0009] Therefore, through the above search, it is found that the hardness testing equipment in the prior art is not good at clamping samples when testing irregular shaped samples. Summary of the invention

DETAILED DESCRIPTION

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] See also Figure 1-11As shown, the present invention is a laboratory hardness test equipment, including a workpiece table 1 for placing samples and a hardness tester 2 located above the workpiece table 1 for testing the hardness of the samples. The hardness tester 2 used in the present invention is an existing known product, such as the HR-150A new manual digital display Rockwell hardness tester. As a known existing product, its hardness testing principle and operation method are known, so they are not described in detail. The side of the workpiece table 1 is annularly arranged, and a plurality of sliding seats 17 are embedded and rotatably connected to the side of the workpiece table 1. The sliding seat 17 is L-shaped, and a movable seat 3 is embedded and plugged into the horizontal part of the sliding seat 17. The movable seat 3 is provided with a mounting column 7, and a matching ring seat 14 and a movable ring seat 15 used in conjunction with the matching ring seat 14 are sleeved on the mounting column 7. A movable part is installed on the movable ring seat 15, and a clamping block 5 for clamping the sample is provided on the movable part.

[0042] In order to realize the rotation of the clamping block 5 along the sample placed on the workpiece table 1 and ensure that the clamping block 5 reaches the side of the sample that is more suitable for clamping, in this embodiment, a first direction adjustment mechanism is installed between the movable seat 3 and the workpiece table 1, and the first direction adjustment mechanism is used to control the movable seat 3 to revolve along the workpiece table 1, and the first direction adjustment mechanism includes a table edge bevel gear ring 6 fixed to the side of the workpiece table 1, and the side of the sliding seat 17 is rotatably connected to a table edge bevel gear block 11 meshing with the table edge bevel gear ring 6, and one end face of the table edge bevel gear block 11 is fixedly connected to a table edge spur gear 10.

[0043] It should be noted that by applying power to the table edge spur gear 10 to make it rotate, the table edge bevel gear block 11 fixedly connected to the table edge spur gear 10 can be rotated, and the table edge bevel gear block 11 is meshed and connected with the table edge bevel gear ring 6, so that the table edge bevel gear block 11 rolls on the table edge bevel gear ring 6 when rotating, so that the sliding seat 17 can be rotated and moved along the side of the workpiece table 1. The number of sliding seats 17 in this scheme corresponds to the number of groups of the plurality of clamping blocks 5. In addition, the sliding seat 17 in this scheme is damped with the contact surface of the side of the workpiece table 1. Under the action of friction, it is ensured that the sliding seat 17 can only move when the table edge bevel gear block 11 rolls along the tooth surface of the table edge bevel gear ring 6, thereby realizing position adjustment, i.e. preventing the sliding seat 17 from shifting and shaking.

[0044] In order to prevent the clamp 5 from interfering with the side of the irregularly shaped sample when the sample is placed on the workpiece table 1, in this embodiment, a second direction adjustment mechanism is installed on the movable seat 3 for controlling the sliding of the second direction adjustment mechanism along the horizontal part of the sliding seat 17. The second direction adjustment mechanism includes a screw rod 28 that passes through the inner wall of the movable seat 3 and is fixedly connected to the vertical part of the sliding seat 17. A plurality of universal wheels 12 are installed on the lower surface of the movable seat 3. One end of the screw rod 28 close to the sliding seat 17 is threadedly connected to a transmission spur gear 25 that is rotatably connected to the movable seat 3.

[0045] It should be noted that, by applying power to the transmission spur gear 25 to make it rotate, and utilizing the threaded connection between the transmission spur gear 25 and the screw rod 28, the transmission spur gear 25 can be driven to drive the movable seat 3 to slide relative to the side portion of the sliding seat 17 while rotating relative to the movable seat 3, so that a plurality of clamping blocks 5 installed on the movable seat 3 on the surface of the sliding seat 17 can be moved synchronously, and the distance from the side of the workpiece table 1 can be adjusted, that is, the initial horizontal distance between the clamping blocks 5 and the side of the sample can be adjusted. In addition, the universal wheel 12 used in this scheme can provide support when the sliding seat 17 revolves around the workpiece table 1, that is, it can ensure the horizontal support of the sliding seat 17, and prevent the sliding seat 17 from generating friction at its bottom edge during the revolution.

[0046] In order to facilitate the adjustment of the number of clamping blocks 5 on the mounting column 7, in this embodiment, the cylindrical surface of the mounting column 7 is arranged in a keyway shape along the length direction, and support blocks 8 embedded in the upper surface of the movable seat 3 are sleeved at both ends of the mounting column 7, and the matching ring seat 14 and the movable ring seat 15 are detachably sleeved on the mounting column 7.

[0047] It should be noted that by removing the support block 8 at one end, there is no interference at one end of the mounting column 7, and the corresponding number of mating ring seats 14 and movable ring seats 15 are installed or slid out on the mounting column 7 using the keyway on the surface of the mounting column 7. In addition, the support block 8, the mating ring seat 14 and the movable ring seat 15 are connected to the keyway part on the mounting column 7 by bolts, so the corresponding equally distributed threaded holes can be machined on the keyway groove wall on the mounting column 7.

[0048] In order to ensure that the clamping block 5 clamps the relatively flat and adaptable part of the irregular side of the sample, in this embodiment, a third directional adjustment mechanism for controlling the extension and retraction of the movable part is installed on the movable ring seat 15, and the third directional adjustment mechanism includes a circular ring 37 rotatably installed on the outer edge of the movable ring seat 15, and one side of the outer wall of the circular ring 37 is rotatably connected to the edge bevel gear ring 35, and the other side is rotatably connected to the edge bevel gear block 36 meshing with the edge bevel gear ring 35.

[0049] It should be noted that the purpose of providing the matching ring seat 14 is to assist the movable ring seat 15 to ensure that the circular ring 37 on the surface of the movable ring seat 15 can rotate smoothly. In this scheme, by applying power to the edge bevel gear ring 35 to rotate it, the edge bevel gear block 36 in meshing connection can be rotated. In addition, the edge bevel gear ring 35 and the circular ring 37 in this scheme also have damping cooperation, that is, to ensure that the edge bevel gear ring 35 will only rotate under the action of external force, and by adjusting the friction coefficient, it can also be ensured that the edge bevel gear ring 35 is locked when the threaded barrel 4 is tilted, thereby preventing the edge bevel gear block 36 from rotating, thereby preventing the clamping block 5 from shifting in position.

[0050] In order to ensure that the clamping block 5 can smoothly clamp the sample, in this embodiment, the movable parts include a threaded rod 34, a threaded barrel 4 and a telescopic rod 13. The threaded rod 34 is fixedly connected to the end face of the edge bevel gear block 36. A threaded barrel 4 is threadedly sleeved on the threaded rod 34. The telescopic rod 13 is fixedly connected to the outer wall of the threaded barrel 4. The telescopic end of the telescopic rod 13 and the end face of the cylinder body are respectively connected to the threaded barrel 4 and the outer wall of the ring 37. The end of the threaded barrel 4 away from the mounting column 7 is fixedly connected to a fixing seat 33. A hydraulic rod 9 is installed in the fixing seat 33. The clamping block 5 is threadedly connected to the piston rod end face of the hydraulic rod 9.

[0051] It should be noted that, by rotating the edge bevel gear block 36 to drive the threaded rod 34 fixedly connected thereto to rotate, under the condition that the threaded barrel 4 cannot rotate, the threaded barrel 4 moves relative to the center line of the movable ring seat 15 as the threaded rod 34 rotates, so that the hydraulic rod 9 on the end face of the threaded barrel 4 and the clamping block 5 installed at its telescopic end can be moved, so that the clamping block 5 reaches different height positions on the side of the sample, and then the hydraulic rod 9 is extended to move the clamping block 5 to clamp the side of the sample. In addition, the surface of the cylinder body of the hydraulic rod 9 in this scheme is hollowed out, and it is also connected to the fixed seat 33 on the threaded barrel 4 by bolts. Therefore, by adjusting the bolts to connect with the hollow parts at different positions on the surface of the hydraulic rod 9, or by using bolts to install hydraulic rods 9 with different telescopic strokes in the fixed seat 33, and screwing the clamping block 5 on the telescopic end of the hydraulic rod 9, it can be ensured that the clamping block 5 far away from the workpiece table 1 has enough movement distance to make it tightly against the side of the sample.

[0052] In order to adjust the distribution intervals of a plurality of clamping blocks 5 on a mounting column 7 to ensure uniform clamping, in this embodiment, a fourth direction adjustment mechanism for controlling the deflection of the movable part is installed on the mating ring seat 14, and the fourth direction adjustment mechanism includes a worm 30 movably installed on the mating ring seat 14 and a worm wheel ring 29 fixed to an end of a circular ring 37 close to the mating ring seat 14, both ends of the worm 30 are provided with sockets 32 plugged into the mating ring seat 14, and one end of the worm 30 extends outward and is fixedly connected to a mating bevel gear block 16, and a pneumatic telescopic rod 31 connected to the socket 32 ​​is fixedly connected to the end face of the mating ring seat 14.

[0053] It should be noted that by applying power to the mating bevel gear block 16 to make it rotate, the worm 30 can be driven to rotate, and then the worm wheel ring 29 drives the circular ring 37 to rotate, and then the circular ring 37 drives the edge bevel gear ring 35 and the edge bevel gear block 36 to revolve around the mounting column 7 at the same time, so that the inclination angle of the threaded barrel 4 on the mounting column 7 can be adjusted, so that several threaded barrels 4 on the mounting column 7 are staggered, that is, the position of several clamping blocks 5 installed on the mounting column 7 is staggered. In addition, the worm 30 and the worm wheel ring 29 provided in this scheme have self-locking properties, that is, when the worm 30 loses the rotational force and the worm 30 and the worm wheel ring 29 remain in an engaged state, the circular ring 37 will not swing down due to the gravity of the tilted threaded barrel 4. , causing the circular ring 37 to drive the worm gear ring 29 to rotate. In addition, the role of the pneumatic telescopic rod 31 provided in the present scheme is to ensure that the matching ring seat 14 and the movable ring seat 15 are smoothly installed. Specifically, after fixing the position of the matching ring seat 14 first, the pneumatic telescopic rod 31 is extended to realize that the socket 32 ​​at the corresponding position drives the worm 30 to descend a certain distance, so that when the movable ring seat 15 is subsequently installed, the worm gear ring 29 on the end face of the circular ring 37 can smoothly reach the top of the worm 30, and then the worm 30 is manually moved to align the spiral groove on the surface of the worm 30 with the tooth groove on the surface of the worm gear ring 29, and then the pneumatic telescopic rod 31 can be contracted to realize that the socket 32 ​​drives the worm 30 to rise and mesh with the worm gear ring 29 just above.

[0054] In order to ensure the smooth operation of the first direction adjustment mechanism, the second direction adjustment mechanism, the third direction adjustment mechanism and the fourth direction adjustment mechanism, in this embodiment, a driving mechanism is installed on the movable seat 3, and the driving mechanism includes a screw rod 21 rotatably connected to the movable seat 3, the screw rod 21 is driven by the driving motor on the movable seat 3, and a slider 22 plugged into the movable seat 3 is threadedly connected to the screw rod 21, and one end of the slider 22 is rotatably connected to an electric push rod 27, and the telescopic end of the electric push rod 27 is fixedly connected to an adjusting motor 20. The adjusting motor 20 in this scheme can select a common servo motor on the market, and the main shaft of the adjusting motor 20 is fixedly connected to an adjusting bevel gear block 19, and the end face of the adjusting bevel gear block 19 is fixedly connected to an adjusting spur gear 18, and the adjusting bevel gear block 19 is used to mesh with the mating bevel gear block 16 and the edge bevel gear ring 35, and the adjusting spur gear 18 is used to mesh with the table edge spur gear 10 and the transmission spur gear 25.

[0055] It should be noted that the adjusting motor 20 is started to realize the rotation of the adjusting bevel gear block 19 and the adjusting spur gear 18 of its main shaft. At this time, the adjusting spur gear 18 is meshed and connected with the transmission spur gear 25. Therefore, the rotation of the adjusting spur gear 18 can realize the rotation of the transmission spur gear 25, that is, the transmission spur gear 25 is applied with a rotating force, and the driving motor drives the screw rod 21 to rotate. Under the condition that the slider 22 is plugged into the movable seat 3, the slider 22 moves with the rotation of the screw rod 21, and the slider 22 drives the adjusting motor 20 and the adjusting bevel gear block 19 and the adjusting spur gear 18 of its main shaft to move to the table edge bevel gear block 11, the matching bevel gear block 11, and the matching bevel gear block 11. When the gear block 16, the edge bevel gear ring 35 or the table edge spur gear 10 are at the position of the adjusting motor 20, the position of the adjusting motor 20 is rotated and dialed, and then the adjusting motor 20 drives the adjusting bevel gear block 19 and the adjusting spur gear 18 to rotate to achieve angle fine-tuning to ensure smooth meshing. The adjusting bevel gear block 19 can be meshed with the matching bevel gear block 16 or the edge bevel gear ring 35, and the matching bevel gear block 16 or the edge bevel gear ring 35 can be applied with a rotational force by rotating the adjusting bevel gear block 19. Similarly, when the adjusting spur gear 18 swings with the position of the adjusting motor 20 to mesh with the table edge spur gear 10, a rotational force can be applied to the table edge spur gear 10.

[0056] In order to adjust the position of the swing adjustment motor 20, in this embodiment, an electric telescopic rod 26 is fixedly connected to the surface of the slider 22, the telescopic end of the electric telescopic rod 26 is fixedly connected to the rack 24, and the electric push rod 27 is fixedly connected to the rotation point of the slider 22 with an adjustment spur gear ring 23 meshing with the rack 24.

[0057] It should be noted that the distance between the adjusting motor 20 and the adjusting bevel gear block 19 and the adjusting spur gear 18 of the main shaft and the slider 22 can be adjusted by extending and retracting the electric push rod 27, and the rack 24 can be moved by extending and retracting the electric telescopic rod 26, so that the adjusting spur gear ring 23 meshing with the rack 24 can drive the electric push rod 27, the adjusting motor 20 and the adjusting bevel gear block 19 and the adjusting spur gear 18 of the rotating shaft to rotate, thereby achieving position adjustment, so as to ensure that the adjusting bevel gear block 19 and the adjusting spur gear 18 rotate to apply rotational power to the transmission spur gear 25, the table edge spur gear 10, the matching bevel gear block 16 or the edge bevel gear ring 35.

[0058] The working principle of the present invention is as follows: first, according to the needs, remove the support block 8 at one end of the mounting column 7, configure the corresponding number of matching ring seats 14 and movable ring seats 15 according to the number of clamping blocks 5 installed on the mounting column 7, first install the matching ring seat 14, and the worm 30 on the matching ring seat 14 is lowered a certain distance, and then the movable ring seat 15 is installed, and the worm wheel ring 29 on the movable ring seat 15 is kept located directly above the worm 30 on the matching ring seat 14, the position of the matching ring seat 14 is fixed, and then the worm 30 is rotated a certain angle so that the worm 30 can rise and reset to mesh with the worm wheel ring 29, according to the above method, a corresponding number of clamping blocks 5 are installed on the mounting column 7, and after the installation is completed, the support block 8 is installed and reset to support the mounting column 7, and then the slider 22 is used to drive the adjusting motor 20 to move the table edge spur gear 10 when the screw rod 21 rotates, and then the position of the adjusting motor 20 is adjusted so that the adjusting spur gear 18 of its main shaft is meshed with the table edge spur gear 10, and the adjusting motor 20 is used to drive The movable adjusting spur gear 18 rotates to drive the table edge spur gear 10 to rotate, so that the table edge bevel gear block 11 can roll on the table edge bevel gear ring 6, so that the sliding seat 17 drives the clamping block 5 to revolve around the workpiece table 1 to achieve position adjustment, and then the position of the adjusting motor 20 is adjusted again, so that the adjusting spur gear 18 of its main shaft is meshed with the transmission spur gear 25, so that the transmission spur gear 25 can drive the movable seat 3 to slide on the surface of the sliding seat 17, and adjust the distance between the clamping block 5 and the workpiece table 1, and then the position of the adjusting motor 20 is adjusted again, so that the adjusting bevel gear block 19 of its main shaft is meshed with the matching bevel gear block 16, so that the worm 30 can drive the worm wheel ring 29 to rotate, and the circular ring 37 can drive the threaded barrel 4 and the clamping block 5 to rotate and swing, and the position of the adjusting motor 20 is adjusted again, so that the adjusting bevel gear block 19 of its main shaft is meshed with the edge bevel gear ring 35, so that the edge bevel gear ring 35 can drive the edge bevel gear block 36 to rotate, and the threaded barrel 4 can drive the clamping block 5 to achieve height adjustment.
