Description

Technical Field

[0001] This utility model relates to the field of corrosion testing equipment technology, and in particular to a corrosion test block grinding fixture. Background Technology

[0002] Corrosion testing is a materials test that detects the chemical or physical (or mechanical-chemical) damage processes caused by the interaction of metals or other materials with their environment. It is an important means of understanding the characteristics of the corrosion system formed by materials and their environment, comprehending the corrosion mechanism, and thus controlling the corrosion process.

[0003] In the existing technology, in the early stage of the experiment, it is necessary to collect the spindles of each product and cut them into 25*25*4mm test blocks using wire cutting. After the test blocks are cut, they need to be ground flat using a grinding machine. Due to the small size and unevenness of the test blocks, the inherent fixtures on the grinding machine are not precise enough when holding the test blocks, and the test blocks are not held stably enough, making the grinding of the test blocks difficult and inefficient.

[0004] To address this, we propose a grinding fixture for corrosion test blocks that can be externally attached to a grinding machine to clamp the test blocks securely and stably. Utility Model Content

[0005] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a corrosion test block grinding fixture to solve the problem that the test block grinding fixture in the corrosion experiment is not stable enough.

[0006] To achieve the above and other related objectives, this utility model provides a corrosion test block grinding fixture, comprising: a base, a clamping assembly, an angle adjusting assembly, and a clamping compensation component;

[0007] The clamping assembly is located above the base and connected to the base on the side. The clamping assembly is used to clamp the test block. The angle adjustment assembly is installed on the upper surface of the base, and the movable end of the angle adjustment assembly is connected to the bottom of the clamping assembly to push the clamping assembly to rotate. The clamping compensation component is located in the middle of the upper end of the clamping assembly. The clamping compensation component is used to fill the gap between the clamping assembly and the test block.

[0008] Preferably, the clamping compensation component includes two symmetrically distributed clamping blocks, which are connected to each other. Each of the two clamping blocks has an inwardly recessed notch on its opposite side. The notches of the two clamping blocks together form a semi-enclosed space for placing and clamping the test block.

[0009] The outer walls of both clamping blocks are semi-circular, and when the two clamping blocks are closed, they together form a circle.

[0010] Preferably, the lower ends of both clamping blocks are connected to a plurality of pads, a portion of each pad extending below the notch of the clamping block to support the clamped test block, and each pad is connected to only one clamping block to avoid motion interference between the two clamping blocks;

[0011] A pad is provided between the two clamping blocks, and the pad is located at the upper end of the pad.

[0012] Preferably, the lower surface of each clamping block is connected to an arc-shaped rib, the inner inclined surface of the arc-shaped rib matches the outer surface of the gasket, the thickness of the arc-shaped rib exceeds the thickness of the gasket, and the arc-shaped rib is used to support the clamping block.

[0013] Preferably, the clamping assembly includes a fixed base, the upper surface of which is provided with a clamping part, and a driving part is installed inside the upper end of the fixed base. The driving part is used to drive the clamping part to squeeze and clamp the test block.

[0014] Preferably, the clamping part includes several arc-shaped clamps, all of which are circumferentially distributed around the center of the fixing seat for clamping an object at the center of the upper end of the fixing seat. The lower end of each arc-shaped clamp is connected to a long strip baffle, and the lower end of each long strip baffle is connected to a slider. The upper surface of the fixing seat is provided with a groove corresponding to each slider, and each long strip baffle is located above a groove and completely covers the groove.

[0015] Preferably, the upper end of the fixing base is provided with an upwardly protruding ring, which is used to limit the position of the test block;

[0016] The side of the fixed base extends outward to form a rotating shaft, and a connecting block is installed on the upper side of the base. The bottom end of the rotating shaft is rotatably connected to the connecting block.

[0017] Preferably, the angle adjustment assembly includes a slide rail mounted on the upper surface of the base, a slide rod slidably connected inside the slide rail, an electric push rod connected to the inner side wall of the slide rail, the telescopic end of the electric push rod being connected to the middle of the slide rod, the electric push rod being used to push the slide rod to move left and right along the slide rail, a support block being connected to the lower end of the fixed base, and two symmetrical adjustment rods being connected between the support block and the slide rod.

[0018] Preferably, each of the adjusting rods is connected to a rotating ring at both ends, and the sliding rod and the support block pass through four rotating rings at both ends and are rotatably connected to the rotating rings.

[0019] Preferably, the base has through holes at all four corners for connecting the base to an external grinding machine using bolts.

[0020] As described above, the corrosion test block grinding fixture disclosed in this utility model has the following beneficial effects:

[0021] This invention employs two semi-circular iron clamping blocks, each with a recess corresponding to the sample block to be ground, for holding the sample block. The two clamping blocks holding the sample block are then inserted into the grinding wheel of the grinding machine. This overcomes the defect of traditional clamping fixtures where the clamping end does not match the shape of the sample block. In addition, shims are provided to cover the bottom of the recesses of the clamping blocks. Furthermore, the shims compensate for the thickness of the sample block, making the grinding surface of the sample block higher than the top of the clamping blocks for easier grinding, thus improving the stability of holding the sample block. Iron shims are welded to the bottom of the clamping blocks to support the sample block.

[0022] Meanwhile, an angle adjustment component for the rotatable clamping assembly is also provided. The slide bar is pushed by an electric push rod to move along the slide rail. The slide bar pushes the adjustment rod to move and tilt one end up. The adjustment rod pushes the fixed base to rotate and stand up through the support block, so that the test block can be ground in a vertical plane. This makes it convenient to place the clamping compensation component and the test block on the plane and then clamp them. It avoids the problem that the test block is easy to fall when it is placed vertically, and the problem that the operator's hand is easily pinched when holding the clamping compensation component for clamping.

[0023] Therefore, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value. Attached Figure Description

[0037] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0038] Please see Figures 1 to 6 It should be understood that the structures, proportions, sizes, etc., illustrated in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of this invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of this invention, should still fall within the scope of the disclosed technical content. Furthermore, the terms "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and not intended to limit the scope of this invention.

[0039] like Figure 1-6 As shown, this utility model provides a corrosion test block grinding fixture, including: a base 1, a clamping assembly 2, an angle adjusting assembly 3, and a clamping compensation component 4;

[0040] The clamping assembly 2 is located above the base 1 and connected to the base 1 on the side. The clamping assembly 2 is used to clamp the test block. The angle adjustment assembly 3 is installed on the upper surface of the base 1, and the movable end of the angle adjustment assembly 3 is connected to the bottom of the clamping assembly 2. It is used to push the clamping assembly 2 to rotate. The clamping compensation component 4 is located in the middle of the upper end of the clamping assembly 2. The clamping compensation component 4 is used to fill the gap between the clamping assembly 2 and the test block, assist the clamping assembly 2 in clamping, and make the clamped test block more stable.

[0041] In one embodiment, please refer to Figure 1-3The clamping compensation component 4 includes two symmetrically distributed clamping blocks 40, which are connected to each other. Each clamping block 40 has an inwardly recessed notch on its facing side, forming a semi-enclosed space for placing and clamping the test block. The clamping blocks 40 can be made of iron discs, which have high hardness and are readily available in grinding workshops, making them easy to manufacture. They can also be made of other materials with high hardness. The shape of the notches on the clamping blocks 40 can be easily and quickly produced by wire cutting on a lathe. The shapes of the two notches correspond to the shape of the test block to be ground, facilitating the clamping of the test block.

[0042] The outer walls of both clamping blocks 40 are semi-circular, forming a circle when closed. The semi-circular outer walls of the clamping blocks 40 can also be made by wire cutting. The circular structure formed by the two clamping blocks 40 can fit perfectly into the inherent circular fixture of the grinding machine, tightening the grinding machine fixture and pressing the two clamping blocks 40 to clamp the test block, allowing the test block to be placed stably on the grinding machine.

[0043] In one embodiment, please refer to Figure 1-3 Each of the two clamping blocks 40 has several shims 41 connected to its lower end. A portion of each shim 41 extends below the recess of the clamping block 40 to support the clamped test block. Each shim 41 is connected to only one clamping block 40 to avoid interference with the movement of the two clamping blocks 40. The clamping blocks 40 and the shims 41 are connected by welding. The shims 41 can be conventional sticker washers for easy operation in a laboratory. The shims 41 are located at the bottom of the clamping blocks 40 to support the test block. A shim 43 is provided between the two clamping blocks 40, located above the shims 41. The shim 43 is used to compensate for the thickness of the test block, effectively raising its height to prevent the upper surface of the test block from being too thin and thus affecting the grinding process when the two clamping blocks 40 are clamping it.

[0044] In one embodiment, please refer to Figure 1-3 Each clamping block 40 has an arc-shaped rib 42 connected to its lower surface. The inner inclined surface of the arc-shaped rib 42 matches the outer surface of the gasket 41. The thickness of the arc-shaped rib 42 exceeds the thickness of the gasket 41, and the arc-shaped rib 42 is used to support the clamping block 40. The arc-shaped rib 42 can also be used to assist in the installation of the gasket 41, preventing the gasket 41 from being installed at an angle, which would reduce the supporting effect of the gasket 41 on the test block. The bottom of the arc-shaped rib 42 is lower than the bottom of the gasket 41 to prevent the welding point between the gasket 41 and the clamping block 40 from protruding, which would cause the clamping block 40 to be placed unstable.

[0045] In one embodiment, please refer to Figure 1 and Figure 4The clamping assembly 2 includes a fixed base 20, with a clamping part 21 on its upper surface. A driving part 22 is installed inside the upper end of the fixed base 20. The driving part 22 is used to drive the clamping part 21 to compress and clamp the test block. The fixed base 20 supports the clamping part 21 and the driving part 22. The driving part 22 is an electric telescopic mechanism that controls the translation of the clamping part 21 by hydraulic, pneumatic, or electric means, and is used to drive the clamping part 21 to clamp the test block.

[0046] In one embodiment, please refer to Figure 1 and Figure 4 The clamping part 21 includes several arc-shaped clamping plates 210, all of which are circumferentially distributed around the center of the fixing base 20. These plates are used to clamp objects at the upper center of the fixing base 20. There are at least three arc-shaped clamping plates 210, and three or more can form a circular sleeve for easy clamping of circular blocks. A long strip baffle 211 is connected to the lower end of each arc-shaped clamping plate 210, and a slider 212 is connected to the lower end of the long strip baffle 211. The upper surface of the fixing base 20 has a groove corresponding to each slider 212. Each long strip baffle 211 is located above and completely covers a groove. The long strip baffle 211 can cover the groove during sample grinding, preventing powder from entering the groove and affecting the movement of the slider 212. In use, the two clamping blocks 40 hold the test block and place it in the middle of the fixed base 20. The drive unit 22 pushes all the sliders 212 to slide. The sliders 212 drive the arc-shaped clamping plate 210 to move towards the middle of the fixed base 20 through the long baffle 211 and clamp the clamping blocks 40. The height of the arc-shaped clamping plate 210 should be less than the height of the clamping blocks 40 to avoid obstructing the grinding of the test block.

[0047] In one embodiment, please refer to Figure 1 and Figure 4 The upper center of the fixed base 20 is provided with an upwardly protruding ring 23, which is used to limit the position of the test block. The diameter of the ring 23 is slightly larger than the outer diameter of the circle formed when the two clamping blocks 40 are closed. In use, the clamping blocks 40 can be placed directly inside the ring 23 of the fixed base 20 to prevent the two clamping blocks 40 from being too far from the center of the fixed base 20. When the multiple arc-shaped clamping plates 210 are closed, they push the clamping blocks 40 to move, causing the two clamping blocks 40 and the test blocks in the two clamping blocks 40 to be misaligned, resulting in a deviation in the clamping angle and affecting the stability of the grinding sample.

[0048] The side of the fixed base 20 extends outward to form a rotating shaft 24. A connecting block 10 is installed on the upper side of the base 1, and the bottom end of the rotating shaft 24 is rotatably connected to the connecting block 10. The fixed base 20 can rotate around the base 1 via the rotating shaft 24.

[0049] In one embodiment, please refer to Figure 5 and Figure 6The angle adjustment assembly 3 includes a slide rail 30 mounted on the upper surface of the base 1. A slide rod 31 is slidably connected inside the slide rail 30. An electric push rod 32 is connected to the inner wall of the slide rail 30. The telescopic end of the electric push rod 32 is connected to the middle of the slide rod 31. The electric push rod 32 is used to push the slide rod 31 to move left and right along the slide rail 30. A support block 33 is connected to the lower end of the fixed base 20. Two symmetrical adjusting rods 34 are connected between the support block 33 and the slide rod 31. In use, the electric push rod 32 is activated, pushing the slide rod 31 to move horizontally along the slide rail 30. The slide rod 31 pushes the adjusting rod 34 to move and tilt one end upwards. The adjusting rod 34 pushes the fixed base 20 to rotate and stand upright via the support block 33, facilitating vertical grinding and preventing all the powder generated during grinding from falling onto the fixed base 20.

[0050] In one embodiment, please refer to Figure 5 and Figure 6 Each adjusting rod 34 has a rotating ring 340 connected to both ends. The sliding rod 31 and the support block 33 are respectively connected to the four rotating rings 340 through both ends and rotated. The rotating rings 340 serve as a transition, facilitating relative rotation between the adjusting rod 34 and the sliding rod 31 and the support block 33.

[0051] In one embodiment, please refer to Figure 1 The base 1 has through holes at all four corners for connecting the base 1 to an external grinding machine using bolts.

[0052] The specific usage process of this utility model is as follows;

[0053] The test block is placed in the recess of the two semi-closed clamps 40, and the test block is supported by the shim 41.

[0054] The two clamping blocks 40 that hold the test block are placed into the ring 23 of the fixed base 20, so that the driving part 22 pushes all the arc-shaped clamping plates 210 to move towards the center position of the fixed base 20, and applies pressure to the sides of the two semi-circular clamping blocks 40, so that the two clamping blocks 40 contract and clamp the test block.

[0055] Start the electric push rod 32. The electric push rod 32 pushes the slide rod 31 to move along the slide rail 30. The slide rod 31 pushes the adjusting rod 34 to move and raise one end. The adjusting rod 34 pushes the fixed seat 20 to rotate and stand up through the support block 33, so that the test block can be ground in the vertical plane.

[0056] In summary, the corrosion test block grinding fixture of this utility model uses two semi-circular iron clamping blocks 40. The clamping blocks 40 have recesses corresponding to the test blocks to be ground for clamping the test blocks. The two clamping blocks 40 holding the test blocks are then inserted into the grinding wheel of the grinding machine. This overcomes the defect of the clamping end of the traditional fixture not matching the shape of the test block, and improves the stability of clamping the test block. Iron pads 41 are welded to the bottom of the clamping blocks 40 for supporting the test blocks.

[0057] Meanwhile, an angle adjustment component 3 of the rotatable clamping component 2 is also provided. The electric push rod 32 pushes the slide rod 31 to move along the slide rail 30. The slide rod 31 pushes the adjustment rod 34 to move and raise one end. The adjustment rod 34 pushes the fixed seat 20 to rotate and stand upright through the support block 33, so that the test block can be ground in the vertical plane. This makes it convenient to place the clamping compensation component 4 and the test block on the plane and then perform the clamping operation. It avoids the problem that the test block is easy to fall when it is placed upright, and the operator's hand is easily pinched when holding the clamping compensation component 4 for clamping operation.

[0058] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
