Description

Technical Field

[0001] This utility model relates to a testing device, and more particularly to a welding material wear resistance testing device. Background Technology

[0002] Wear-resistant welding consumables are commonly used in high-friction, high-impact environments, such as mining, metallurgy, and construction industries. To ensure the reliability and durability of these consumables in practical applications, their wear resistance is crucial. Wear resistance testing allows for the evaluation of key parameters such as wear resistance index, strength, and hardness under actual operating conditions, thereby ensuring that their quality and performance meet relevant standards and requirements.

[0003] For example, a wear-resistant material wear resistance strength testing device disclosed in Chinese Patent Publication No. CN221445741U belongs to the technical field of testing equipment. It includes a shell, and two support rods are fixedly connected inside the shell. The top ends of the two support rods are fixedly connected to a fixing plate. The upper surface of the fixing plate is threaded with two fixing rods, and the bottom ends of the two fixing rods are fixedly connected to anti-slip blocks. Through the setting of a discharge trough, a collection trough, a collection box and an electric fan, and through the cooperation of the fixing plate, fixing rods and a grinding plate, the wear-resistant material can be quickly fixed by the fixing rods and fixing plate. Then, the motor drives the grinding plate to rotate and grind it, thereby achieving the effect of rapid fixing and testing. Subsequently, the electric fan blows the debris, causing the debris to be blown and quickly discharged and collected through the discharge trough and collection trough. The debris falls into the collection box by inertia, thereby achieving the effect of rapid cleaning and collection.

[0004] The aforementioned existing wear resistance strength testing device for wear-resistant materials has some problems. First, the required abrasive varies depending on the welding material, making it impossible to change the appropriate abrasive according to the testing requirements. Second, the pressure between the abrasive and the welding material needs to be precisely controlled during the wear resistance testing process, and the use of an electric telescopic rod makes it difficult to accurately control the downward pressure of the abrasive.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-6This utility model provides a technical solution: a welding material wear resistance testing device, including a base 1, a support frame 2 fixedly connected to the base 1, a drive motor 201 fixedly connected to one side of the support frame 2 via a motor bracket, a three-grip chuck 202 fixedly connected to the output end of the drive motor 201, a grinding test piece 3 held in the three-grip chuck 202, an L-shaped bracket 4 fixedly connected to the base 1 and located on one side of the base 1, and T-shaped grooves 402 symmetrically opened on the L-shaped bracket 4, the T-shaped grooves 402 containing... A T-shaped slider 501 is slidably installed. A connecting push plate 5 is fixedly connected to the T-shaped slider 501. A base plate 502 is fixedly connected between the two connecting push plates 5. A mounting plate 505 is fixedly connected to one end of the base plate 502. A limiting groove 506 is opened on the other side of the mounting plate 505. A limiting welding pad 7 is slidably installed in the limiting groove 506. A welding material 702 to be tested is welded on one side of the limiting welding pad 7. A support platform 8 is set on one side of the limiting welding pad 7. A connecting rope 9 is fixedly connected to the support platform 8.

[0024] In this embodiment, the welding material 702 to be tested is welded onto the limiting weld overlay pad 7, and then the limiting weld overlay pad 7 is inserted into the limiting slide groove 506. The support platform 8 is connected to the connecting push plate 5 via the connecting rope 9. The connecting push plate 5 is slidably mounted above the L-shaped bracket 4 via the T-shaped slider 501. The weight of the support platform 8 itself can drive the connecting push plate 5 to move. The movement of the connecting push plate 5 will drive the mounting plate 505 to move closer to the three-jaw chuck 202. The mounting plate 505 can drive the limiting weld overlay pad 7 to move, so that the welding material 702 to be tested on the limiting weld overlay pad 7 is attached to the end face of the grinding test piece 3, and continuous pressure is applied to the welding material 702 to be tested. 02. With constant thrust, starting the drive motor 201 can drive the three-jaw chuck 202 to rotate. The rotation of the three-jaw chuck 202 will drive the grinding inspection piece 3 to rotate. The grinding inspection piece 3 can be used to grind the surface of the welding material 702 to be tested. After a period of time, observe the grinding condition of the surface of the welding material 702 to be tested. When the welding material 702 to be tested is completely ground off, the test is considered unreasonable. If the welding material 702 to be tested is left behind or not ground off at all, the test is considered qualified. The grinding inspection piece 3 is fixed by clamping it with the three-jaw chuck 202, which makes it easy to replace the grinding inspection piece 3 with one of the corresponding materials according to the material of the welding material 702 to be tested later.

[0025] To achieve the purpose of fixing the limiting solder pad 7 within the limiting slide groove 506, the device adopts the following technical solution: a limiting slide rod 401 is fixedly connected to the bottom of the L-shaped bracket 4, and a first guide wheel 403 is rotatably installed on the L-shaped bracket 4. A limiting groove 6 is opened on the front of one of the connecting push plates 5, and a return spring 601 is fixedly connected in the limiting groove 6. A limiting pin 602 is fixedly connected to the other end of the return spring 601, and a displacement handle 603 is fixedly connected to the limiting pin 602. A limiting hole 701 is opened on the other side of the limiting solder pad 7, and the limiting hole 701 cooperates with the limiting pin 602.

[0026] The return spring 601 can provide a certain pushing force to the limit pin 602. When the limit pin 602 is pushed, it will move and insert into the limit hole 701, thereby fixing the limit solder pad 7 inside the limit slide groove 506. The displacement handle 603 can drive the limit pin 602 to move.

[0027] In order to achieve the purpose of pulling the welding material 702 to be tested to fit the grinding test piece 3, the device adopts the following technical solution: a connecting sleeve block 801 is fixedly connected to one side of the support platform 8, the connecting sleeve block 801 slides with the limiting slide rod 401, a vertical rod 802 is fixedly connected to the support platform 8, a counterweight plate 803 is sleeved on the vertical rod 802, a second guide wheel 504 is rotatably installed between the two connecting push plates 5, the second guide wheel 504, the first guide wheel 403 cooperate with the connecting rope 9, and a connecting ear 503 is fixedly connected to one side of the base plate 502, the connecting ear 503 is fixedly connected to the connecting rope 9.

[0028] By sliding the connecting sleeve 801 and the limiting slide rod 401, the support platform 8 can only move up and down. By adjusting the number of counterweight plates 803 sleeved on the base plate 502, the mass of the support platform 8 can be adjusted. The weight of the support platform 8 will be transmitted to the connecting push plate 5 through 9, pulling the welding material 702 to be tested against the grinding test piece 3 to avoid it. Adjusting the weight of the support platform 8 can adjust the pressure between the welding material 702 to be tested and the grinding test piece 3. The direction of the connecting rope 9 can be adjusted by using the second guide wheel 504 and the first guide wheel 403, so that the connecting rope 9 pulls the welding material 702 to be tested closer to the grinding test piece 3.

[0029] The working principle and usage process of this utility model are as follows: During use, the welding material 702 to be tested needs to be welded onto the limiting welding plate 7. Then, the limiting welding plate 7 is inserted into the limiting slide groove 506. According to testing needs, the number of counterweight plates 803 is adjusted to change the weight of the support platform 8. Then, through the transmission of the connecting rope 9, the connecting push plate 5 is pulled towards the grinding test piece 3, so that the welding material 702 to be tested and the grinding test piece 3 are in contact. The drive motor 201 is started to drive the three-jaw chuck 202 to rotate. The rotation of the three-jaw chuck 202 can in turn drive the grinding test piece 3 to rotate. The rotation of the grinding test piece 3 will cause friction with the welding material 702 to be tested, thus performing a wear resistance test on the welding material 702. After a certain period, the drive motor 201 is stopped, the limiting welding plate 7 is removed, and the amount of welding material 702 remaining on the surface of the limiting welding plate 7 is observed. Based on the preset comparison, it can be analyzed whether the wear resistance of the welding material 702 meets the standard.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
