Description

TECHNICAL FIELD

[0001] The present application relates to the field of mechanical fixation, and in particular to a hammer type Brinell hardness tester fixing system. BACKGROUND

[0002] In the field of industrial manufacturing and material testing, the hardness of materials is one of the key indicators to measure their mechanical properties, which plays a decisive role in product quality control, performance evaluation and process optimization. Brinell hardness testing method has been widely used in many industries such as aerospace, automobile manufacturing, mechanical processing, etc. due to its accurate test results and good repeatability. With the continuous improvement of the requirements of modern industry on material quality and performance, the precision and stability of Brinell hardness testing become increasingly important, prompting the continuous innovation of related detection equipment and technology to meet the upgrading of industrial demand.

[0003] When the traditional Brinell hardness tester is tested, in order to ensure the accuracy and stability of the test, the hardness tester needs to be reliably fixed on the surface of the object to be tested. There are many commonly used fixing methods in the past, one of which is to use a simple clamp to fix the hardness tester and the object to be tested by the clamping force of the clamp. Such a clamp is generally made of metal material, and the clamping function is realized by tightening the screw or bolt. Another common way is to use a magnetic adsorption device to adsorb the hardness tester on the surface of the object to be tested by the magnetic force generated by the permanent magnet or electromagnet. In some cases, the paste method is used to temporarily fix the hardness tester on the object by using special glue. These traditional fixing methods can meet the basic test requirements to some extent, but they all have their own limitations.

[0004] For the related technology in the above, although the simple clamp fixing method can provide a certain clamping force, it is difficult to achieve stable fixation when facing irregularly shaped objects to be tested, and it is easy to shake and displace, thereby affecting the accuracy of the test results. The adsorption force of the magnetic adsorption device is greatly affected by the material and surface condition of the object, and if the surface of the object to be tested is uneven or the material has weak magnetism, the adsorption effect will be greatly reduced. The paste method is not only more complicated to operate, but the glue may also contaminate the surface of the object to be tested, and it is difficult to reuse, so there is an urgent need for a hammer type Brinell hardness tester fixing system to solve the above problems.

[0031] The following is combined with Figures 1-6 This application is described in further detail.

[0032] The embodiment of the present application discloses a hammer-type Brinell hardness tester fixing system. Figure 1 as well as Figure 2 A hammer-type Brinell hardness tester fixing system includes a mounting mechanism 1, a connecting mechanism 2, and a positioning mechanism 3. The connecting mechanism 2 is mounted on a support ring 101 and is connected to a pressing assembly 104 for linkage. Typically, the connecting mechanism 2 and the positioning mechanism 3 are integrated, with at least one set of positioning mechanisms 3 connected to the mounting mechanism 1 to position the hardness tester. Through the coordinated cooperation of the three, the hammer-type Brinell hardness tester can be stably fixed to the surface of the object to be tested, avoiding shaking and displacement during the test, thereby improving the accuracy of the test results.

[0033] In specific work, first, the hammer type Brinell hardness tester is placed in the support ring 101, further through the rotating connecting mechanism 2 with the pressing assembly 104, at this time the anti-reverse assembly 105 works, so that the connecting mechanism 2 can only be one-way rotation, further through the pressing assembly 104 to clamp the hammer type Brinell hardness tester in the support ring 101, then through the connecting mechanism 2 to connect the positioning mechanism 3 on the support ring 101, further, the hammer type Brinell hardness tester is installed to the measured position, at this time, the connecting mechanism 2 is rotated again to lock the hammer type Brinell hardness tester, then, the positioning mechanism 3 is fixed with the surface of the measured object, after the fixing is completed, the hardness of the measured object is tested by artificial method.

[0034] With reference to Figures 2-6 The mounting mechanism 1 includes a support ring 101, a pressing assembly 104 connected to the support ring 101, and an anti-reverse assembly 105. The support ring 101 can be made of high-strength metal material, such as stainless steel, etc., which has good rigidity and stability, and can withstand certain pressure and impact force. The outer edge of the support ring 101 is provided with a first mounting groove 102, which can be formed by milling or other methods, for installing subsequent parts. The first mounting groove 102 is provided with at least three groups of mounting ports 103, the number of which can be adjusted according to actual needs, and usually three or more groups can provide more stable support to the hardness tester from multiple directions.

[0035] Each group of mounting ports 103 is provided with a group of pressing assemblies 104. The pressing assembly 104 includes a pressing rod 1041 vertically arranged in the mounting port 103, which is slidingly connected to the support ring 101. As a preferred embodiment, a t-shaped groove is provided on the support ring, a sliding block is arranged in the t-shaped groove, and the pressing rod 1041 is provided with a sliding block. The pressing rod 1041 can be made of a solid metal rod, and its surface is treated to be smooth to reduce friction with other parts. The pressing rod 1041 is rotatably connected with a pressing block 1042, and the pressing rod 1041 penetrates through the pressing block 1042. The pressing block 1042 can rotate around the pressing rod 1041, and one end of the pressing block 1042 is hinged to the connecting mechanism 2. The end of the pressing block 1042 away from the connecting ring 203 is provided with a pressing inclined surface 1043, which has high roughness and can make clamping more stable. The inclined surface design can make the pressing block 1042 better fit the surface of the measured object during pressing, increase the contact area, and improve the fixing effect.

[0036] The support circle is also provided with an anti-inversion assembly 105. The anti-inversion assembly 105 comprises a third mounting groove 1051 provided on the support circle 101, and a plurality of blocking blocks 1052 provided on the third mounting groove 1051, which can be a protruding structure integrally formed in the third mounting groove 1051. The anti-inversion assembly 105 also comprises a plurality of anti-inversion blocks 1053 hingedly connected in the third mounting groove 1051, which correspond to the blocking blocks 1052 one by one, and each group of anti-inversion blocks 1053 is provided with a group of blocking blocks 1052 on one side, and the anti-inversion blocks 1053 are provided with an anti-inversion spring 1054 on the side pointing to the third mounting groove 1051, and the other end of the anti-inversion spring 1054 is connected to the third mounting groove 1051. In addition, the connecting ring 203 is also provided with an anti-inversion protrusion 1055.

[0037] When the mounting mechanism 1 is in operation, the support circle 101 provides basic support for the entire mounting mechanism 1, ensuring that the system can be stably placed on the surface of the object to be measured. When the connecting mechanism 2 is in action, it will drive the pressing block 1042 to slide on the pressing rod 1041. Since the pressing block 1042 is hingedly connected to the connecting mechanism 2, the movement of the connecting mechanism 2 causes the pressing block 1042 and the pressing rod 1041 to move, and the pressing inclined surface 1043 of the pressing block 1042 contacts the Brinell hardness tester and exerts pressure on the surface of the Brinell hardness tester, thereby fixing the Brinell hardness tester in the support circle 101. The function of the anti-inversion assembly 105 is to ensure the stability of the system. When the connecting ring 203 rotates, the anti-inversion protrusion 1055 rotates with the connecting ring 203. If the connecting ring 203 has a tendency to rotate in the opposite direction, the anti-inversion protrusion 1055 will cooperate with the anti-inversion block 1053. The anti-inversion block 1053 maintains a certain position under the elastic force of the anti-inversion spring 1054, blocks the anti-inversion protrusion 1055 from moving in the opposite direction, and thereby prevents the connecting ring 203 from rotating in the opposite direction, avoiding the loosening of the system during the test.

[0038] Referring to Figures 2-6 The connecting mechanism 2 is provided with a profiling connecting piece 207 arranged in the second mounting groove 205, which can be sleeved on the connecting protrusion 204, and the profiling connecting piece 207 is provided with a second threaded hole 208. The first threaded hole 206 and the second threaded hole 208 can be connected by bolts. The profiling connecting piece 207 is provided with a mounting rod 209, and the side of the mounting rod 209 away from the profiling connecting piece 207 is provided with a locking assembly 210. The connecting block 201 can be made of materials with good sliding properties, and its shape is adapted to the first mounting groove 102, so it can slide freely in the groove. The connecting block 201 is provided with a magnetic attraction assembly 202, which comprises a first magnet 2021 arranged below the connecting block 201, and a second magnet 2022 arranged on the support circle 101. The second magnet 2022 is annular, and the first magnet 2021 and the second magnet can be made of permanent magnet materials such as neodymium iron boron.

[0039] The connecting block 201 is provided with a connecting ring 203 away from one side of the first mounting groove 102, and a circular connecting protrusion 204 is arranged above the connecting ring 203, and a second mounting groove 205 is formed between the connecting protrusion 204 and the supporting ring 101, and a plurality of first threaded holes 206 are uniformly distributed above the connecting protrusion 204.

[0040] The profiled connecting piece 207 can be sleeved on the connecting protrusion 204, one end of the profiled connecting piece 207 is inserted into the second mounting groove 205, and the profiled connecting piece 207 is provided with a second threaded hole 208, and the first threaded hole 206 and the second threaded hole 208 can be connected by bolts. The profiled connecting piece 207 is provided with a mounting rod 209, and the mounting rod 209 is provided with a locking assembly 210 away from one side of the profiled connecting piece 207. The locking assembly 210 generally includes a locking ring 2101, which can be installed on the positioning mechanism 3 by bolts or in one piece, and the locking ring 2101 is provided with a locking bolt 2102, which passes through the locking ring 2101 and can press on the mounting rod 209.

[0041] When the connecting mechanism 2 works, the connecting mechanism 2 connects the positioning mechanism 3 and the mounting mechanism 1, so that the positioning mechanism 3 can position the mounting mechanism 1 and in turn position the Brinell hardness tester. The connecting block 201 slides in the first mounting groove 102, which is the basis for the connecting mechanism 2 to move. The magnetic attraction assembly 202 can keep the connecting block 201 and the supporting ring 101 connected relatively stably through the magnetic attraction between the first magnet 2021 and the second magnet 2022, and also facilitates the sliding of the connecting block 201 in the first mounting groove 102. When the connecting mechanism 2 moves, the connecting ring 203 is manually rotated to drive the pressing assembly 104 connected thereto to move. The connecting protrusion 204 and the profiled connecting piece 207 can be connected by bolts to enhance the connection stability between them, and can also be positioned by the magnetic attraction assembly 202. The mounting rod 209 is used to install other components, and the locking assembly 210 can lock and fix the components installed on the mounting rod 209. By tightening the locking bolt 2102, the friction is increased to prevent the locking rod from rotating, which can adjust the angle of the positioning mechanism 3 to adapt to more irregular objects to be measured.

[0042] Referring to Figures 1-5The positioning mechanism 3 comprises a positioning pipe 301, a suction disc assembly 302, a blocking sheet 303, a positioning rod 304, a positioning assembly 305 and an operating handle 306. The connecting mechanism 2 is connected to the outer wall of the positioning pipe 301 in a manner of bolt connection or welding.

[0043] The blocking sheet 303 is slidably connected in the positioning pipe 301 and can block air in the positioning pipe 301. The blocking sheet 303 can freely slide in the positioning pipe 301. The positioning rod 304 is arranged on the side of the blocking sheet 303 away from the suction disc assembly 302. The positioning rod 304 can be a solid metal rod. The positioning assembly 305 is arranged on the positioning rod 304. The positioning assembly 305 comprises positioning holes 3051 arranged on the positioning rod 304 in a uniform manner and a supporting bin 3052 arranged on one side of the positioning pipe 301. The supporting bin 3052 can be formed by casting. A clamping rod 3053 is slidably connected to the supporting bin 3052. The clamping rod 3053 can be a metal rod. The clamping rod 3053 penetrates through the supporting bin 3052. A handle 3054 is arranged on the side of the clamping rod 3053 away from the positioning rod 304. A positioning block 3055 is arranged on the end of the clamping rod 3053 pointing to the positioning rod 304. The positioning block 3055 can be formed integrally with the clamping rod 3053. The positioning block 3055 can move into the positioning hole 3051. A reset spring 3056 is arranged on the positioning block 3055. The other end of the reset spring 3056 is connected to the supporting bin 3052.

[0044] The positioning mechanism 3 works as follows: first, when the device is placed on the surface of the object to be measured, the flexible ring 3022 of the suction cup 3021 first contacts the surface of the object to be measured. The flexible ring 3022 can better adapt to the surface of the object to be measured of different shapes, and can avoid the unevenness caused by rust on the metal surface. The operator can operate the positioning rod 304 to rotate in the positioning tube 301 by operating the handle 306. When it is necessary to position the positioning rod 304, the knob 3054 is pulled to move the clamping rod 3053. At this time, the positioning rod 304 can slide freely. The blocking piece 303 is moved during the movement of the positioning rod 304, and negative pressure is generated at the suction cup assembly 302, so that the positioning assembly 305 is firmly adsorbed on the workpiece to be measured. When the positioning rod 304 moves to the appropriate position, the positioning rod 304 is rotated, the reset spring 3056 resets the clamping rod 3053, the positioning block 3055 enters the positioning hole 3051, and the positioning of the positioning rod 304 is realized. The suction cup assembly 302 maintains the adsorption state.

[0045] The implementation principle of the hammer type Brinell hardness tester fixing system according to an embodiment of the present application is as follows: the hammer type Brinell hardness tester fixing system cooperates the installation mechanism 1, the connecting mechanism 2 and the positioning mechanism 3, provides stable support by the support ring 101, adjusts the pressing assembly 104 as needed through the connecting mechanism 2, and combines the precise positioning of the positioning mechanism 3 and the adsorption of the suction cup assembly 302 to stably fix the hammer type Brinell hardness tester under different working conditions. Compared with the traditional fixing method, it is not limited by the shape and material of the object to be measured, avoids the influence of shaking and displacement on the test results, greatly improves the accuracy and reliability of the test, reduces the test error, and provides a more effective solution for hardness testing in the fields of industrial manufacturing and material testing. At the same time, the setting of the anti-reverse assembly 105 ensures the stability of the system during operation and prevents the system from being fixed due to accidental reverse rotation.

[0046] The above are preferred embodiments of the present application, and do not limit the protection scope of the present application. Therefore, equivalent changes made on the basis of the structure, shape, principle of the present application should be covered within the protection scope of the present application.
