Description

Technical Field

[0001] The present invention relates to the technical field of hardness detection, and more specifically, it relates to a hardness detection device for valve housing processing. Background Art

[0002] During the processing of valve housings, hardness detection is a crucial step. The hardness of the valve housing directly affects its wear resistance, corrosion resistance, and overall performance during use. Therefore, it is particularly important to accurately detect the hardness of the valve housing raw materials before processing. Currently, hardness detection mainly relies on hardness detection equipment such as Rockwell hardness testers.

[0003] However, in the existing hardness detection process, there is a significant technical problem: the measuring points are not standardized. Specifically, when conducting hardness detection, the inspectors often randomly select the measuring points, resulting in uneven distribution of the measuring points, scattered here and there. This random way of selecting measuring points is not only inefficient but also prone to inaccurate detection data. The randomly selected measuring points are partially concentrated and partially scattered, unable to comprehensively reflect the hardness of each area of the valve housing raw materials, thus affecting the accurate evaluation of the overall performance of the valve housing.

[0004] To solve the above problems, a hardness detection device for valve housing processing is proposed. Summary of the Invention

[0009] A second strip-shaped groove is formed in the U-shaped frame, and the second strip-shaped groove corresponds to avoid the test indenter.

[0010] The present invention is further configured that the elastic telescopic assembly includes a telescopic sleeve disposed on the adjusting plate, a pushing spring disposed in the telescopic sleeve, and a telescopic column movably mounted on the telescopic sleeve;

[0011] One end of the pushing spring abuts against the adjusting plate, and the other end of the pushing spring abuts against one end of the pushing telescopic column, and the rotating assembly is disposed at the end of the telescopic column away from the pushing spring.

[0014] The present invention is further configured that a spring groove is formed at the end of the first turntable away from the first rubber pad, and the fixed-point angle assembly is disposed in the spring groove.

[0015] The present invention is further configured that the fixed-point angle assembly includes a return spring disposed in the spring groove, and a positioning column movably inserted into the spring groove.

[0016] The present invention is further configured that a plurality of positioning holes are annularly arranged at the top end of the telescopic sleeve, and the positioning holes and the positioning columns are inserted in a matching manner.

[0017] The present invention is further configured that a spherical surface is disposed at the end of the positioning column away from the return spring, and a wedge-shaped surface is formed at the top end of the positioning hole.

[0018] The present invention is further configured that a threaded tube is disposed on the U-shaped frame, and the threaded tube and the first turntable are coaxial;

[0019] The second clamping mechanism includes a threaded rod disposed on the threaded tube, and a second turntable disposed at the lower end of the threaded rod, and a second rubber pad is disposed at the bottom end of the second turntable.

[0020] The present invention is further configured that a tooth groove is formed at the bottom end of the adjusting plate, and the tooth groove is linearly arranged along the length direction of the adjusting plate;

This way of measuring point distribution can comprehensively cover all regions of the metal block, avoiding the randomness problem of uneven measuring point distribution and scattered points in the traditional detection method, thereby significantly improving the accuracy and comprehensiveness of the hardness detection data. At the same time, through the setting of the fixed-point angle component, the metal block can easily achieve rapid switching of equal-angle measuring points during the detection process, making the measuring point distribution of the detection more uniform, and further improving the comprehensiveness and accuracy of the detection data.

[0026] 2. In the present invention, the detection personnel can flexibly adjust the diameter of the measuring point circular array according to different sizes of valve housing raw material metal blocks. This function is achieved by the sliding adjustment of the adjusting plate in the installation groove, enabling the device to be applicable to the detection requirements of metal blocks of various sizes. By adjusting the diameter of the measuring point circle, the present invention ensures that regardless of the size of the metal block, all regions thereof can be evenly and comprehensively detected, which not only improves the accuracy and reliability of the detection, but also enhances the versatility and practicality of the device.

[0037] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the drawings and in combination with the embodiments.

[0038] It should be pointed out that unless otherwise specified, all technical and scientific terms used in the present application have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present application belongs.

[0039] In the present invention, unless otherwise stated, the orientations such as "upper, lower" are usually in the directions shown in the drawings, or in the vertical, perpendicular or gravitational directions; similarly, for the sake of easy understanding and description, "left, right" are usually in the left and right shown in the drawings; "inside, outside" refer to the inside and outside relative to the contours of the respective components, but the above orientation terms do not limit the present invention.

[0040] Embodiment, please refer to Figure 1 - Figure 9A hardness testing device for valve housing processing, comprising a hardness tester 1, and a support platform 2 and a test pressure head 3 are arranged on the hardness tester 1, a mounting groove 201 and a No. 1 strip groove 202 are opened on the support platform 2, and an adjustment plate 4 is slidably installed in the mounting groove 201, a U-shaped frame 5 is arranged at the top of the adjustment plate 4, and the two ends of the U-shaped frame 5 are fixedly connected with the two sides of the top of the adjustment plate 4 by bolts;

[0041] A No. 1 clamping mechanism 6 is disposed on the adjustment plate 4, and the No. 1 clamping mechanism 6 is slidably matched with the No. 1 strip groove 202, and a No. 2 clamping mechanism 7 is disposed on the U-shaped frame 5, and the No. 2 clamping mechanism 7 and the No. 1 clamping mechanism 6 are coaxially corresponding;

[0042] The first clamping mechanism 6 includes an elastic telescopic component 8 disposed on the adjustment plate 4, a rotating component 9 disposed on the top of the elastic telescopic component 8, and a fixed-point angle component 10 disposed on the rotating component 9;

[0043] A second strip groove 501 is formed on the U-shaped frame 5 , and the second strip groove 501 corresponds to the avoidance test pressure head 3 .

[0044] The hardness tester 1, the support platform 2 and the test pressure head 3 are Rockwell hardness testers in the prior art. The test pressure head 3 is located directly above the support platform 2. The valve housing raw metal block to be tested is placed on the support platform 2 and then the height of the support platform 2 is adjusted by the lifting mechanism, so that the test pressure head 3 can perform hardness testing on the metal block. In the present invention, the mounting groove 201 is opened through the support platform 2, and the mounting groove 201 is connected to the No. 1 strip groove 202, wherein the No. 1 strip groove 202 is located on one side of the center position of the mounting groove 201, the adjustment plate 4 is movably inserted into the mounting groove 201, and both ends of the adjustment plate 4 are located outside the mounting groove 201. After the two ends of the U-shaped frame 5 are fixedly connected to the two sides of the top of the adjustment plate 4 by bolts, the U-shaped frame 5 spans above the support platform 2.

[0045] Specifically, when detecting the raw metal block of the valve housing to be detected, the metal block is placed in the middle position between the U-shaped frame 5 and the support table 2. The metal block needs to be located between the first clamping mechanism 6 and the second clamping mechanism 7, and the metal block also needs to be directly below the test indenter 3. At this time, by adjusting the second clamping mechanism 7, the distance between the first clamping mechanism 6 and the second clamping mechanism 7 becomes smaller, thereby clamping the metal block. At this time, according to the size of the metal block, the distance between the first clamping mechanism 6 and the second clamping mechanism 7 to the axis of the test indenter 3 is adjusted, so that when the metal block rotates and switches the measuring points under the clamping of the first clamping mechanism 6 and the second clamping mechanism 7, the measuring points can be more evenly distributed on the metal block, so that the hardness detection data is more accurate. Otherwise, if the metal block is large and the diameter of the circular distribution of the measuring points is small, then the detection data is relatively concentrated, and for the whole metal block, the reference of multiple groups of data is poor. It should be noted that the adjusted distance needs to ensure that when the clamped metal block rotates, there is always a position directly below the test indenter 3.

[0046] Furthermore, in the initial state of the first clamping mechanism 6, under the action of the elastic telescopic component 8, its top protrudes from the plane of the top of the support table 2. Under the push of the second clamping mechanism 7, the metal block compresses the elastic telescopic component 8, so that the rotating component 9 and the elastic telescopic component 8 are both located inside the first strip-shaped groove 202, and the bottom surface of the metal block fits the top of the support table 2. At this time, the test indenter 3 of the hardness detector 1 applies pressure to the metal block, and records the magnitude of the force applied by the test indenter 3 and the indentation depth generated on the metal block.

[0047] When it is necessary to switch the measuring point after the test of this measuring point is completed, by adjusting the second clamping mechanism 7 upward, the elastic telescopic component 8 restores its elastic force, thereby pushing the metal block upward, so that the bottom surface of the metal block is separated from the top of the support table 2. It should be noted that although the second clamping mechanism 7 is adjusted upward, the first clamping mechanism 6 and the second clamping mechanism 7 still have a firm clamping force on the metal block. At this time, the metal block is rotated, and the metal block rotates at an angle through the rotating component 9, thereby switching the measuring point. At the same time, through the setting of the fixed-point angle component 10, when it rotates to a certain angle, a clicking sound will be emitted, thereby reminding that the measuring point position has been switched. At this time, the second clamping mechanism 7 is adjusted downward again, so that the metal block moves downward and fits the top of the support table 2, and the hardness of the measuring point is detected again.

[0048] By rotating the metal block, multiple measurement points are detected, so that the measurement points are arranged in a circular array, and the diameter of the circular array of measurement points can be realized by moving the adjusting plate 4, so that appropriate circular array measurement point detection can be carried out according to metal blocks of different sizes to be measured, thereby improving the hardness detection data of the metal block. The elastic telescopic component 8 includes a telescopic sleeve 801 arranged on the adjusting plate 4, a pushing spring 802 arranged in the telescopic sleeve 801, and a telescopic column 803 movably installed on the telescopic sleeve 801;

[0049] One end of the pushing spring 802 abuts against the adjusting plate 4, and the other end of the pushing spring 802 abuts against and pushes one end of the telescopic column 803. The rotating component 9 is arranged at the end of the telescopic column 803 away from the pushing spring 802.

[0050] The telescopic sleeve 801 is welded to the top of the adjusting plate 4, and its diameter matches the width of the first strip-shaped groove 202. Under the action of the pushing spring 802, the telescopic column 803 drives the rotating component 9 to protrude from the first strip-shaped groove 202, so that when the metal block placed on the rotating component 9 needs to switch the measurement point, the metal block rotates around the clamping axis of the first clamping mechanism 6 and the second clamping mechanism 7, so as to switch the position of the metal block under the test indenter 3. After the measurement point of the rotating and switching measurement point metal block is detected, the detected measurement points form a circular circle, so as to obtain the detection data in each position direction on the metal block, so that its detection data is more valuable for recording.

[0051] Among them, the pushing spring 802 drives the rotating component 9 to protrude from the first strip-shaped groove 202 and is located above the support table 2, so that when the metal block switches the measurement point, the metal block is separated from the top of the support table 2, so that except for the clamping of the first clamping mechanism 6 and the second clamping mechanism 7, the rest of the metal block is suspended, making it easier to rotate and adjust the angle.

[0052] The rotating component 9 includes a first turntable 901 arranged on the telescopic column 803, and a first rubber pad 902 arranged on the first turntable 901;

[0053] The first turntable 901 is rotatably sleeved on the end of the telescopic column 803 away from the pushing spring 802, and the first rubber pad 902 is arranged at the end of the first turntable 901 away from the telescopic column 803.

[0054] A spring groove 903 is formed at the end of the first turntable 901 away from the first rubber pad 902, and the fixed-point angle component 10 is arranged in the spring groove 903.

[0055] The maximum diameter of the first turntable 901 is the same as the outer diameter of the telescopic sleeve 801. When the second clamping mechanism 7 is adjusted to approach the first turntable 901, it pushes the metal block downward, causing the first turntable 901 to retract into the first strip-shaped groove 202 along with the telescopic column 803. It should be noted that in the initial state, when the pushing spring 802 pushes the telescopic column 803 upward to the highest point, although the top end of the first turntable 901 protrudes from the plane of the top end of the support platform 2, the bottom end of the first turntable 901 sleeved on the telescopic column 803 is lower than the plane of the top end of the support platform 2 and is located in the first strip-shaped groove 202. This is mainly to ensure that when the second clamping mechanism 7 is adjusted and the metal block is pushed downward, the first turntable 901 can smoothly enter the first strip-shaped groove 202. If the bottom end of the first turntable 901 also protrudes from the plane of the top end of the support platform 2, then when the first turntable 901 moves downward, it will collide with the two side walls of the first strip-shaped groove 202 due to deviation and thus cannot smoothly enter the first strip-shaped groove 202.

[0056] Preferably, by providing a first rubber pad 902 on the first turntable 901, when a hardness test is performed after the metal block is clamped, a good relative static state can be maintained between the metal block and the first turntable 901. That is, when the metal block is pushed to rotate to switch the measurement point, the first turntable 901 can be driven to rotate accordingly, so as to achieve equal-angle switching through the fixed-point angle assembly 10, thereby improving the accuracy of the measurement data.

[0057] The fixed-point angle assembly 10 includes a return spring 1001 disposed in the spring groove 903 and a positioning column 1002 movably inserted into the spring groove 903.

[0058] A plurality of positioning holes 804 are annularly arranged at the top end of the telescopic sleeve 801, and the positioning holes 804 are matched and inserted with the positioning column 1002.

[0059] A spherical surface 1003 is provided at one end of the positioning column 1002 away from the return spring 1001, and a wedge surface 805 is provided at the top end of the positioning hole 804.

[0060] One fixed-point angle assembly 10 is provided, and the first turntable 901 is sequentially clamped with the annularly arranged positioning holes on the telescopic sleeve 801 through rotation, so as to realize equal-angle switching of the measurement points of the metal block clamped on the first turntable 901.

[0061] Specifically, after measuring the hardness of one point of the metal block, when it is necessary to switch the measuring point, the second clamping mechanism 7 is adjusted upward, and under the action of the push spring 802, the first turntable 901 moves up to above the top of the support table 2. When the first turntable 901 moves up, it drives the positioning column 1002 to move up from the original positioning hole 804. When the first turntable 901 moves up to the highest point, the spherical surface 1003 on the positioning column 1002 corresponds to the wedge surface 805 at the top of the positioning hole 804 and does not detach from the positioning hole 804. At this time, when the metal block is rotated to switch the measuring point , the No. 1 turntable 901 rotates, thereby driving the spherical surface 1003 of the positioning column 1002 to contact the wedge surface 805 of the positioning hole 804, so that the positioning column 1002 squeezes the reset spring 1001 to insert into the spring groove 903, and the spherical surface of the positioning column 1002 contacts the top of the telescopic sleeve 801 as the No. 1 turntable 901 rotates until it moves to another positioning hole 804. The rebound force of the reset spring 1001 pushes the positioning column 1002 into the positioning hole 804 and emits a click prompt sound. At this time, the equal-angle switching of the metal block measuring point is completed.

[0062] Furthermore, after the measurement point is completed, the No. 2 clamping mechanism 7 is adjusted downward again to push the metal block downward so that the No. 1 turntable 901 enters the No. 1 strip groove 202, and the bottom end of the metal block contacts the top of the support table 2. At this time, the positioning column 1002 is completely inserted into the positioning hole 804 as the No. 1 turntable 901 moves downward, and the spherical surface 1003 is located at the bottom of the positioning hole 804, which does not correspond to the wedge surface 805 on the positioning hole 804, so that the metal block cannot rotate at this time, thereby ensuring the accuracy of the measuring point position.

[0063] A threaded tube 502 is provided on the U-shaped frame 5, and the threaded tube 502 and the first turntable 901 are coaxial;

[0064] The second clamping mechanism 7 includes a threaded rod 701 arranged on the threaded tube 502 , and a second turntable 702 arranged at the lower end of the threaded rod 701 , and a second rubber pad 703 is arranged at the bottom end of the second turntable 702 .

[0065] The threaded rod 701 threads through the threaded tube 502, and the No. 2 turntable 702 and the No. 2 rubber pad 703 correspond to the No. 1 turntable 901 and the No. 1 rubber pad 902, so as to clamp the metal block to be tested. Through the arrangement of the No. 1 rubber pad 902 and the No. 2 rubber pad 703, the clamped metal block and the No. 1 turntable 901 and the No. 2 turntable 702 can remain relatively still, thereby avoiding the metal block from rotating offset, so that when the No. 1 turntable 901 and the No. 2 turntable 702 rotate to switch measuring points, the measuring points can be switched at equal angles, thereby improving the accuracy of the detection data.

[0066] The bottom end of the adjustment plate 4 is provided with tooth grooves 401, and the tooth grooves 401 are arranged in a linear array along the length direction of the adjustment plate 4;

[0067] One end of the bottom of the installation groove 201 is provided with a clamping mechanism 11, and the clamping mechanism 11 is clamped and matched with the tooth groove 401.

[0068] A storage groove 203 is formed at one end of the bottom of the installation groove 201, and the clamping mechanism 11 is arranged in the storage groove 203;

[0069] The clamping mechanism 11 includes a compression spring 1101 arranged in the storage groove 203, and a clamping block 1102 movably arranged in the storage groove 203 and clamped and matched with the tooth groove 401.

[0070] The adjusting plate 4 slides and adjusts in the installation groove 201, so as to adjust the axial distance between the first clamping mechanism 6 and the second clamping mechanism 7 and the axis of the test indenter 3, that is, to adjust the radius of the ring formed by the measured points on the metal block. After adjusting the radius of the ring of the measured points on the metal block according to the size of the metal block, under the action of the compression spring 1101, the clamping block 1102 is pushed to be clamped with the tooth groove 401 on the adjusting plate 4, so as to lock the adjusted position. It should be noted that the cross section of the clamping between the tooth groove 401 and the clamping block 1102 is triangular. The triangular setting enables the adjusting plate 4 to be directly pulled when moving and adjusting, and the operation is more convenient.

[0071] In all the above-mentioned solutions, for the connection between two components, welding, the cooperation connection of bolts and nuts, bolt or screw connection or other well-known connection methods can be selected according to the actual situation, which will not be elaborated one by one here. For those mentioned above involving fixed connection, welding is preferably considered. Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and deformations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
