Description

Technical Field

[0001] This invention belongs to the field of corrosion resistance testing technology, and more specifically, relates to a corrosion resistance testing device for power tool striker materials. Background Technology

[0002] As a core component of power tools, the striker is often exposed to humid, oily, or chemically corrosive environments. If the material is not corrosion resistant enough, it will lead to surface rust, reduced mechanical strength, and even breakage risk. Therefore, the corrosion resistance of the raw materials must be tested before the striker of power tools is manufactured.

[0003] The current corrosion resistance testing equipment still has the following problems: 1. It cannot be guaranteed that the corrosion resistance testing equipment is in a tilted state when the waste liquid is discharged after use, which makes it easy for waste liquid to remain; 2. It cannot assist in mixing the liquid before corrosion resistance testing, resulting in uneven liquid composition, and some parts of the corrosion resistance testing equipment are easily damaged under stress, affecting service life; 3. Before the corrosion resistance testing equipment is in operation, the operator's hands cannot be in a safe area, which poses a significant safety hazard. Summary of the Invention

[0004] This disclosure relates to a corrosion resistance testing device for power tool striker materials, comprising a liquid storage component, a positioning clamping component, an auxiliary testing component, a mixing protection component, and an active control component. When the output shafts of the two electric telescopic rods a retract, the multi-functional plate moves upward, causing the liquid storage shell to tilt. The force on the four arc-shaped auxiliary plates is essentially offset by eight arc-shaped protective grooves and eight circular protective rods, providing protection for the four electric telescopic rods d and improving their service life. When the operator presses the corresponding button on the control panel, both hands are in a safe area, minimizing safety risks. This device solves the problems of residual waste liquid after use, the inability to mix the liquid before corrosion resistance testing, and the inability of the operator's hands to be in a safe area.

[0010] In at least some embodiments, the auxiliary test piece further includes: an arc-shaped auxiliary plate and an electric telescopic rod d; there are four arc-shaped auxiliary plates, and the four arc-shaped auxiliary plates are fixedly installed on the inner ends of four circular mounting rods; there are four electric telescopic rods d, and the four electric telescopic rods d are fixedly installed on the liquid storage shell, and the output shafts of the four electric telescopic rods d are fixedly connected to the four circular mounting rods.

[0011] In at least some embodiments, the mixing protection component includes: a rectangular mixing plate and a circular protective rod; the rectangular mixing plate is fixedly installed on the outside of the circular protective rod; there are two circular protective rods, and the two circular protective rods are slidably installed on the rectangular mixing plate; the bottom of the two circular protective rods is provided with rounded corners, and the bottom of the two circular protective rods is in contact with the liquid storage shell.

[0012] In at least some embodiments, the hybrid protective component further includes: a force-bearing ring and a helical spring a; there are two force-bearing rings, and the two force-bearing rings are fixedly installed on the outside of the two circular protective rods; there are two helical springs a, and the two helical springs a are sleeved on the outside of the two circular protective rods, and the two helical springs a are located between the rectangular hybrid plate and the two force-bearing rings.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. In this invention, when the output shafts of the two electric telescopic rods c extend, the two positioning clamping blocks can automatically clamp the test pin material; when the output shafts of the two electric telescopic rods c retract, the two positioning clamping blocks separate from the test pin material; when the output shaft of the electric telescopic rod b extends, the test pin material moves from top to bottom; when the output shaft of the electric telescopic rod b retracts, the test pin material moves from bottom to top, thus realizing the reciprocating test of the test pin material.

[0017] In addition, when the output shafts of the two electric telescopic rods a retract, the multi-functional plate moves upward, causing the liquid storage shell to tilt; when the multi-functional plate moves upward, the rectangular drain trough a aligns with the rectangular drain trough b, which facilitates the discharge of liquid from the liquid storage shell.

[0018] 2. When the output shafts of the four electric telescopic rods d extend, the inner walls of the four arc-shaped auxiliary plates can contact the impact pin material, and the four arc-shaped auxiliary plates are interference-fitted with the impact pin material. Since the inner walls of the four arc-shaped auxiliary plates have a concave-convex structure, when the impact pin material moves up and down, the four arc-shaped auxiliary plates can remove the oxide layer on the outer surface of the impact pin material, so that the impact pin material with the oxide layer removed can directly contact the liquid in the liquid storage shell, which is beneficial for simulating the corrosion resistance of the impact pin material after use. When the output shafts of the four electric telescopic rods d extend, the four rectangular mixing plates move, which pushes the liquid in the liquid storage shell, making the composition of the liquid in the liquid storage shell more uniform when used.

[0019] Furthermore, when the output shafts of the four electric telescopic rods d extend, the bottoms of the eight circular protective rods are inserted into the eight arc-shaped protective grooves, which limit the movement of the four circular mounting rods. When the impact pin material moves up and down, the four arc-shaped auxiliary plates will generate swaying and outward thrust under the action of the impact pin material. The swaying and thrusting forces on the four arc-shaped auxiliary plates can be basically canceled out by the eight arc-shaped protective grooves and the eight circular protective rods, ensuring that the swaying and thrusting forces on the four arc-shaped auxiliary plates will not be transmitted to the output shafts of the four electric telescopic rods d through the four circular mounting rods. This protects the four electric telescopic rods d and helps to improve their service life. When the output shafts of the four electric telescopic rods d retract, the eight helical springs a can be compressed, causing the eight circular protective rods to automatically separate from the eight arc-shaped protective grooves.

[0020] 3. The operator of this invention can control the operation of electric telescopic rods a, b, c, and d via the control panel; the circular mounting shaft allows the control panel to follow the angle changes of the movable mounting frame.

[0021] In addition, the two helical springs b provide elastic support for the movable mounting frame. When the detection button is pressed and the operator presses the corresponding button on the control panel, the output shaft of the electric telescopic rod b can extend or retract. When the detection button is not pressed and the operator presses the corresponding button on the control panel, the output shaft of the electric telescopic rod b cannot extend or retract. This ensures that before the output shaft of the electric telescopic rod b extends or retracts, one of the operator's hands needs to press the top of the control panel to automatically press the detection button. When the operator presses the corresponding button on the control panel, both of the operator's hands are in a safe area, minimizing safety risks. Attached Figure Description

[0046] Its specific function is as follows: Since the two electric telescopic rods c203 are fixedly installed on the U-shaped clamping seat 202, and the two positioning clamping blocks 204 are fixedly installed on the output shafts of the two electric telescopic rods c203, when the output shafts of the two electric telescopic rods c203 extend, the two positioning clamping blocks 204 can automatically clamp the test pin material 300; when the output shafts of the two electric telescopic rods c203 retract, the two positioning clamping blocks 204 separate from the test pin material 300; since the electric telescopic rod b201 is fixedly installed on the mounting bracket 102, and the U-shaped clamping seat 202 is fixedly installed on the output shaft of the electric telescopic rod b201, when the output shaft of the electric telescopic rod b201 extends, the pin material 300 moves from top to bottom; when the output shaft of the electric telescopic rod b201 retracts, the pin material 300 moves from bottom to top, thus realizing the reciprocating test of the pin material 300.

[0047] Furthermore, since the multi-functional plate 103 is slidably mounted on the liquid storage shell 101, and the two electric telescopic rods a104 are fixedly mounted on the liquid storage shell 101, and the output shafts of the two electric telescopic rods a104 are fixedly connected to the multi-functional plate 103, when the output shafts of the two electric telescopic rods a104 retract, the multi-functional plate 103 moves upward, causing the liquid storage shell 101 to tilt; and since the liquid storage shell 101 is provided with a rectangular drain groove a1012, and the multi-functional plate 103 is provided with a rectangular drain groove b1031, when the multi-functional plate 103 moves upward, the rectangular drain groove a1012 and the rectangular drain groove b1031 are aligned, which is conducive to the discharge of liquid from the liquid storage shell 101.

[0048] In this embodiment of the disclosure, such as Figures 6 to 8As shown, the auxiliary test piece 400 includes: an auxiliary test frame 401 and circular mounting rods 402; the auxiliary test frame 401 is fixedly installed inside the liquid storage shell 101; there are four circular mounting rods 402, and the four circular mounting rods 402 are slidably installed on the auxiliary test frame 401; the auxiliary test piece 400 also includes: an arc-shaped auxiliary plate 403 and an electric telescopic rod d404; there are four arc-shaped auxiliary plates 403, and the four arc-shaped auxiliary plates 403 are fixedly installed on the inner ends of the four circular mounting rods 402; there are four electric telescopic rods d404, and the four electric telescopic rods d404 are fixedly installed on the liquid storage shell 101, and the output shafts of the four electric telescopic rods d404 are fixedly connected to the four circular mounting rods 402;

[0049] The mixing protection component 500 includes: a rectangular mixing plate 501 and circular protective rods 502; the rectangular mixing plate 501 is fixedly installed on the outside of the circular mounting rod 402; two circular protective rods 502 are provided, and the two circular protective rods 502 are slidably installed on the rectangular mixing plate 501; the bottom of the two circular protective rods 502 is provided with rounded corners, and the bottom of the two circular protective rods 502 is in contact with the liquid storage shell 101; the mixing protection component 500 also includes: a force-bearing ring 503 and a helical spring a504; two force-bearing rings 503 are provided, and the two force-bearing rings 503 are fixedly installed on the outside of the two circular protective rods 502; two helical springs a504 are provided, and the two helical springs a504 are sleeved on the outside of the two circular protective rods 502, and the two helical springs a504 are located between the rectangular mixing plate 501 and the two force-bearing rings 503;

[0050] Its specific function is as follows: Four arc-shaped auxiliary plates 403 are fixedly installed on the inner ends of four circular mounting rods 402, and four electric telescopic rods d404 are fixedly installed on the liquid storage shell 101. The output shafts of the four electric telescopic rods d404 are fixedly connected to the four circular mounting rods 402. When the output shafts of the four electric telescopic rods d404 extend, the inner walls of the four arc-shaped auxiliary plates 403 can contact the impact pin material 300. The four arc-shaped auxiliary plates 403 and the impact pin material 300 are interference-fitted. Because the inner walls of the four arc-shaped auxiliary plates 403 have a concave-convex surface structure, when the impact pin material 300... When moving downwards, the four arc-shaped auxiliary plates 403 can remove the oxide layer on the outer surface of the impact pin material 300, allowing the impact pin material 300 with the oxide layer removed to directly contact the liquid in the liquid storage shell 101, which is beneficial for simulating and testing the corrosion resistance of the impact pin material 300 after use; and since the four rectangular mixing plates 501 are fixedly installed on the outside of the four circular mounting rods 402, when the output shafts of the four electric telescopic rods d404 extend, the four rectangular mixing plates 501 move, which pushes the liquid in the liquid storage shell 101, making the composition of the liquid in the liquid storage shell 101 more uniform when used;

[0051] Furthermore, because the liquid storage shell 101 has eight arc-shaped protective grooves 1011, and eight circular protective rods 502 are slidably mounted on four rectangular mixing plates 501, and the bottoms of the eight circular protective rods 502 are rounded, when the output shafts of the four electric telescopic rods d404 extend, the bottoms of the eight circular protective rods 502 are inserted into the eight arc-shaped protective grooves 1011, which limits the movement of the four circular mounting rods 402; when the impact pin material 300 moves up and down, the four arc-shaped auxiliary plates 403 will generate shaking and outward thrust under the action of the impact pin material 300, so that the shaking and thrust on the four arc-shaped auxiliary plates 403 can be basically canceled out by the eight arc-shaped protective grooves 1011 and the eight circular protective rods 502, ensuring that the four arc-shaped auxiliary plates 403 are stable. The swaying and thrusting forces on the auxiliary plate 403 are not transmitted to the output shafts of the four electric telescopic rods d404 through the four circular mounting rods 402, thus protecting the four electric telescopic rods d404 and improving their service life. Furthermore, because the eight force-bearing rings 503 are fixedly installed outside the eight circular protective rods 502, and the eight helical springs a504 are sleeved on the outside of the eight circular protective rods 502, and are located between the four rectangular mixing plates 501 and the eight force-bearing rings 503, when the output shafts of the four electric telescopic rods d404 retract, the eight helical springs a504 can compress, causing the eight circular protective rods 502 to automatically separate from the eight arc-shaped protective grooves 1011.

[0052] In this embodiment of the disclosure, such as Figure 9 and Figure 10 As shown, the movable control component 600 includes: a circular mounting shaft 601, a movable mounting bracket 602, and a control panel 603; the circular mounting shaft 601 is rotatably mounted on the mounting bracket 102; the movable mounting bracket 602 is fixedly mounted on the circular mounting shaft 601; the control panel 603 is fixedly mounted on the movable mounting bracket 602, and the control panel 603 is electrically connected to the electric telescopic rod a104, electric telescopic rod b201, electric telescopic rod c203, and electric telescopic rod d404; the movable control component 600 also includes: a coil spring b604 and a detection button 605; two coil springs b604 are provided, and the two coil springs b604 are fixedly mounted on the movable mounting bracket 602, and the two coil springs b604 are also in contact with the mounting bracket 102; the detection button 605 is fixedly mounted on the mounting bracket 102, and the detection button 605 is electrically connected to the control panel 603;

[0053] Its specific functions are as follows: Since the control panel 603 is fixedly installed on the movable mounting bracket 602, and the control panel 603 is electrically connected to the electric telescopic rods a104, b201, c203 and d404, the operator can control the operation of the electric telescopic rods a104, b201, c203 and d404 through the control panel 603; and since the circular mounting shaft 601 is rotatably installed on the mounting bracket 102, and the movable mounting bracket 602 is fixedly installed on the circular mounting shaft 601, the control panel 603 can change angles with the movable mounting bracket 602.

[0054] Furthermore, since the two helical springs b604 are fixedly installed on the movable mounting bracket 602 and are in contact with the mounting bracket 102, they provide elastic support for the movable mounting bracket 602. Also, since the detection button 605 is fixedly installed on the mounting bracket 102 and is electrically connected to the control panel 603, when the detection button 605 is pressed and the operator presses the corresponding button on the control panel 603, the output shaft of the electric telescopic rod b201 can extend or retract. When the detection button 605 is not pressed and the operator presses the corresponding button on the control panel 603, the output shaft of the electric telescopic rod b201 cannot extend or retract. This ensures that before the output shaft of the electric telescopic rod b201 extends or retracts, one of the operator's hands needs to press the top of the control panel 603 to automatically press the detection button 605. When the operator presses the corresponding button on the control panel 603, both of the operator's hands are in a safe area, minimizing safety risks.

[0055] The specific usage and function of this embodiment are as follows:

[0056] In use, the auxiliary corrosion resistance test liquid is first poured into the liquid storage shell 101. Then, the test pin material 300 is placed between the two positioning clamping blocks 204. Next, the output shafts of the two electric telescopic rods c203 are extended via the control panel 603. At this time, the two positioning clamping blocks 204 automatically clamp the test pin material 300. Then, the output shafts of the four electric telescopic rods d404 are extended via the control panel 603. At this time, the inner walls of the four arc-shaped auxiliary plates 403 can contact the test pin material 300, and the four arc-shaped auxiliary plates 403 are interference-fitted with the test pin material 300. The connection is achieved because the inner walls of the four arc-shaped auxiliary plates 403 have a concave-convex structure. When the impact pin material 300 moves up and down, the four arc-shaped auxiliary plates 403 can remove the oxide layer on the outer surface of the impact pin material 300, allowing the impact pin material 300 with the oxide layer removed to directly contact the liquid in the liquid storage shell 101. This is beneficial for simulating and testing the corrosion resistance of the impact pin material 300 after use. At the same time, the movement of the four rectangular mixing plates 501 promotes the liquid in the liquid storage shell 101, making the composition of the liquid in the liquid storage shell 101 more uniform during use. When the output shafts of the four electric telescopic rods d404 extend... The bottoms of the eight circular protective rods 502 are inserted into the eight arc-shaped protective grooves 1011, which limit the movement of the four circular mounting rods 402. When the firing pin material 300 moves up and down, the four arc-shaped auxiliary plates 403 will generate swaying and outward thrust under the action of the firing pin material 300. The swaying force and thrust on the four arc-shaped auxiliary plates 403 can be basically canceled out by the eight arc-shaped protective grooves 1011 and the eight circular protective rods 502, ensuring that the swaying force and thrust on the four arc-shaped auxiliary plates 403 will not be transmitted to the output shaft of the four electric telescopic rods d404 through the four circular mounting rods 402. The telescopic rod d404 provides protection and helps extend the service life of the four electric telescopic rods d404. Then, the operator presses the top of the control panel 603 with one hand, causing the control panel 603 to automatically press the detection button 605, and then presses the corresponding button on the control panel 603. At this time, both hands of the operator are in a safe area, and the safety hazard is low. When the output shaft of the electric telescopic rod b201 extends, the impact pin material 300 moves from top to bottom; when the output shaft of the electric telescopic rod b201 retracts, the impact pin material 300 moves from bottom to top, realizing the reciprocating test of the impact pin material 300.

[0057] When the output shafts of the two electric telescopic rods c203 retract, the two positioning clamping blocks 204 separate from the tested impact pin material 300; when the output shafts of the four electric telescopic rods d404 retract, the eight helical springs a504 can be compressed, causing the eight circular protective rods 502 to automatically separate from the eight arc-shaped protective grooves 1011.

[0058] When the waste liquid in the liquid storage shell 101 needs to be discharged, the output shafts of the two electric telescopic rods a104 are retracted through the control panel 603. At this time, the multi-function plate 103 moves upward, causing the liquid storage shell 101 to tilt. At the same time, the rectangular drain trough a1012 and the rectangular drain trough b1031 are aligned, which is conducive to the discharge of liquid in the liquid storage shell 101.
