Description

Technical Field

[0001] This utility model relates to the field of diamond grinding wheel processing technology, and in particular to a tooling for dimensional inspection of diamond grinding wheels. Background Technology

[0002] Diamond grinding wheels are circular bonded abrasive tools with a central through-hole, made from diamond abrasive grains and bonded with metal powder, resin powder, ceramics, and electroplated metals. Structurally, diamond grinding wheels are layered, consisting of a dense layer of diamond abrasive grains, a transition layer that acts as a buffer and connector, and a stable supporting matrix. This structure makes them a leader among superhard abrasive wheels. Compared to traditional ordinary abrasive wheels, diamond grinding wheels stand out due to their superior performance. They can easily handle extremely hard and difficult-to-machine materials such as cemented carbide, glass, and ceramics, achieving efficient and precise grinding operations. This not only greatly improves processing efficiency but also ensures the surface finish and dimensional accuracy of the workpiece, meeting the stringent requirements of modern industry for high quality and high precision.

[0003] However, a crucial step in the diamond grinding wheel production process is the rigorous inspection of its dimensions. Previously, this step often relied on manual labor, using measuring rulers to measure each wheel individually. This was not only time-consuming and labor-intensive but also susceptible to human error, making it difficult to guarantee the accuracy of the measurement results. This not only affected the product qualification rate but could also delay subsequent production due to dimensional discrepancies, causing unnecessary economic losses. Utility Model Content

[0004] This utility model discloses a tooling for inspecting the dimensions of diamond grinding wheels, which solves the problems of low accuracy and low efficiency in traditional diamond grinding wheel dimension inspection methods.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A fixture for dimensional inspection of diamond grinding wheels includes a horizontally positioned base plate. A vertical support plate is fixed to one end of the top surface of the base plate. A movable plate parallel to the support plate is movably mounted on the top surface of the base plate. A first driving assembly is provided on the base plate to drive the movable plate closer to or away from the support plate. A horizontal scale is fixed on the side of the movable plate away from the support plate, with a first graduation line on its top surface. A first pointer corresponding to the scale is fixed on the top surface of the base plate. A slider located at the central axis of the movable plate is slidably connected inside the movable plate. A second driving assembly is provided on the movable plate to drive the slider to move up and down along the central axis of the movable plate. A horizontal pressure plate is fixed to the lower part of the side of the slider close to the support plate. A fixing block is fixed to the lower part of the side of the slider away from the pressure plate, with the bottom surface of the fixing block flush with the bottom surface of the pressure plate. A second pointer is fixed to the side of the fixing block. A second graduation line corresponding to the second pointer is provided on the side of the movable plate away from the support plate. A limiting assembly is also provided on the base plate to restrict the diamond grinding wheel at the central axis of the base plate.

[0007] Compared with the prior art, the present invention has the following beneficial effects:

[0008] The first driving component drives the movable plate away from the support plate, and then the diamond grinding wheel is placed horizontally between the support plate and the movable plate. A limiting component restricts the diamond grinding wheel to the central axis of the base plate. The first driving component again ensures that both sides of the diamond grinding wheel are in close contact with the support plate and the movable plate, respectively. The diameter of the diamond grinding wheel can then be determined based on the position of the first pointer on the first scale line. Next, the second driving component drives the slider downwards along the central axis of the movable plate, so that the bottom surface of the pressure plate is in close contact with the top surface of the diamond grinding wheel. The thickness of the diamond grinding wheel can then be determined based on the position of the second pointer on the second scale line. This achieves the measurement of the diamond grinding wheel's dimensions. This invention is highly practical. By setting up a base plate, support plate, movable plate, first driving component, scale, first scale line, first pointer, slider, pressure plate, fixing block, second pointer, second scale line, second driving component, and limiting component, it can simultaneously measure the diameter and thickness of the diamond grinding wheel, effectively improving measurement accuracy and efficiency.

[0014] The specific content of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0015] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model provides a tooling for measuring the size of diamond grinding wheels, including a horizontally arranged base plate 1, a vertical support plate 2 fixed to one end of the top surface of the base plate 1, and a movable plate 3 parallel to the support plate 2 movably mounted on the top surface of the base plate 1. A first driving assembly is provided on the base plate 1 for driving the movable plate 3 closer to or further away from the support plate 2. A horizontal scale 32 is fixed to the side of the movable plate 3 facing away from the support plate 2, and a first scale line 321 is provided on the top surface of the scale 32. A first pointer 331 corresponding to the scale 32 is fixed to the top surface of the base plate 1. A sliding connection is provided within the movable plate 3. The slider 5 is located at the central axis of the 3. The movable plate 3 is provided with a second driving component for driving the slider 5 to move up and down along the central axis of the movable plate 3. A horizontal pressure plate 51 is fixed to the lower part of the side of the slider 5 near the support plate 2. A fixing block 52 is fixed to the lower part of the side of the slider 5 away from the pressure plate 51. The bottom surface of the fixing block 52 is flush with the bottom surface of the pressure plate 51. A second pointer 53 is fixed to the side of the fixing block 52. A second scale line 34 corresponding to the second pointer 53 is provided on the side of the movable plate 3 away from the support plate 2. The base plate 1 is also provided with a limiting component for limiting the diamond grinding wheel 8 at the central axis of the base plate 1.

[0016] like Figure 1 , Figure 2 and Figure 3As shown, the first drive assembly includes several fixed rods 4 horizontally fixed in the base plate 1, several limiting blocks 31 fixed at the bottom end of the movable plate 3, the limiting blocks 31 are all located in the base plate 1 and are slidably connected to the base plate 1, the limiting blocks 31 are slidably connected to the corresponding fixed rods 4 respectively, and the side of the limiting blocks 31 facing away from the support plate 2 is fixed with a spring 41 sleeved on the corresponding fixed rod 4. Several cavities 11 are opened in the base plate 1 for the corresponding limiting blocks 31 and springs 41 to move, and a handle 36 is fixed on the top surface of the movable plate 3. Furthermore, when the spring 41 is in its natural state, the movable plate 3 is in contact with the support plate 2, and the first pointer 331 points to the zero mark on the first scale line 321. Pulling the handle 36 away from the support plate 2 moves the movable plate 3 away from the support plate 2, thereby causing the limiting block 31 to compress the spring 41. Then, the diamond grinding wheel 8 is placed between the support plate 2 and the movable plate 3, and the limiting component restricts the diamond grinding wheel 8 to the central axis of the base plate 1. After releasing the handle 36, the spring 41 will naturally rebound and compress the movable plate 3. At this time, the two sides of the diamond grinding wheel 8 will be in close contact with the support plate 2 and the movable plate 3 respectively, and the diameter of the diamond grinding wheel 8 can be obtained from the position of the first pointer 331 on the first scale line 321.

[0017] like Figure 1 , Figure 2 and Figure 3 As shown, the second driving assembly includes a vertical screw 54 rotatably connected to the top of the slider 5. The screw 54 is located on the central axis of the movable plate 3, and its top end penetrates the top surface of the movable plate 3 and extends to the outside of the movable plate 3. The screw 54 is threadedly connected to the movable plate 3. A rotating disk 55 is fixed to one end of the screw 54 located outside the movable plate 3. A sliding cavity 35 is provided inside the movable plate 3 for the slider 5 and the screw 54 to move. Furthermore, the handle 36 has an L-shaped structure, and the handle 36 and the rotating disk 55 do not interfere with each other. The zero mark of the second scale line 34 is the top surface of the base plate 1. Manually rotating the rotating disk 55 causes the screw 54 to rotate around its own axis, thereby causing the slider 5 to move up and down along the central axis of the movable plate 3, which in turn causes the pressure plate 51 and the fixed block 52 to move up and down synchronously. At this time, the position of the second pointer 53 on the second scale line 34 is the height of the bottom surface of the pressure plate 51.

[0018] like Figure 1 As shown, the top surface of the movable plate 3 is higher than the top surface of the support plate 2, so that when the spring 41 is in its natural state (i.e., the support plate 2 and the movable plate 3 are in contact), the pressure plate 51 can be stored above the support plate 2.

[0019] like Figure 1 and Figure 2As shown, the limiting assembly includes two vertical limiting plates 6, both movably disposed on the side of the support plate 2 near the movable plate 3, and the two limiting plates 6 are symmetrically disposed on both sides of the diamond grinding wheel 8. The support plate 2 is provided with a third driving assembly for driving the two limiting plates 6 to move closer or further apart from each other. An extension plate 61 is movably disposed at the end of each of the two limiting plates 6 away from the support plate 2. A groove 62 is opened at the end of each of the two limiting plates 6 away from the support plate 2. A protrusion 63 corresponding to the groove 62 is fixed at the end of each of the two extension plates 61 near the limiting plate 6. The two limiting plates 6 and the corresponding extension plates 61 are detachably connected by locking bolts 64. After placing the diamond grinding wheel 8 between the support plate 2 and the movable plate 3, the third drive assembly drives the two limiting plates 6 to move closer together, so that both sides of the diamond grinding wheel 8 contact the two limiting plates 6 respectively, thus restricting the diamond grinding wheel 8 to the central axis of the base plate 1. After the inspection is completed, the third drive assembly drives the two limiting plates 6 to move away from each other, so that both limiting plates 6 move out of the space between the support plate 2 and the movable plate 3, thus restoring the spring 41. The extension plate 61 extends the length of the limiting plate 6, thereby meeting the limiting requirements for diamond grinding wheels 8 of different diameters. The groove 62 and the protrusion 63 make the extension plate 61 and the limiting plate 6 more securely fixed. The locking bolt 64 makes it convenient for workers to disassemble and install the extension plate 61. Furthermore, each extension plate 61 can also have a groove 62 at the end away from the limiting plate 6, so that more extension plates 61 can be installed on the limiting plate 6, thereby extending the length of the limiting plate 6 even further.

[0020] like Figure 1 , Figure 2 and Figure 4As shown, the third drive assembly includes a bidirectional lead screw 71 horizontally rotatably connected to the support plate 2. Two symmetrical movable blocks 72 are threaded onto the bidirectional lead screw 71. Each of the two movable blocks 72 has a connecting block 65 fixed at one end, which is fixed to the corresponding limiting plate 6. A fixed seat 7 is fixed at one end of the support plate 2. The end of the bidirectional lead screw 71 near the fixed seat 7 passes through the support plate 2 and extends into the support plate 2. A vertical worm gear 73 is fixed to the surface of the end of the bidirectional lead screw 71 located in the support plate 2. A vertical worm 74 meshes with the worm gear 73 and is rotatably connected in the fixed seat 7. A connecting rod 75 is fixed to the top of the worm 74. The top of the connecting rod 75 passes through the top surface of the fixed seat 7 and extends out of the fixed seat 7. A turntable 76 is fixed to the end of the connecting rod 75 located outside the fixed seat 7. A movable cavity 21 is opened in the support plate 2 for the bidirectional lead screw 71, movable blocks 72 and connecting blocks 65 to move. An inner cavity 77 is opened in the fixed seat 7 for the worm gear 73 and worm 74 to move. Rotating the turntable 76 causes the worm gear 74 to rotate around its own axis via the connecting rod 75. This, in turn, causes the bidirectional lead screw 71 to rotate via the worm wheel 73 that meshes with the worm gear 74. Consequently, the two movable blocks 72 move closer to or further away from each other, which in turn causes the two limiting plates 6 to move closer to or further away from each other, thus restricting the diamond grinding wheel 8 to the central axis of the base plate 1.

[0021] like Figure 1 and Figure 2 As shown, a support block 33 is fixed to the top surface of the base plate 1, and the top surface of the support block 33 is fixed to the corresponding first pointer 331 by a fixing bolt 332. The support block 33 and the fixing bolt 332 can support and fix the first pointer 331. Furthermore, the scale 32 can be set as two symmetrical ones, the first pointer 331 can also be set as two corresponding ones, and the second scale line 34 and the second pointer 53 can also be set as two symmetrical ones, so that the staff can read the dimensions from both sides of the base plate 1.

[0022] like Figure 1 As shown, several supports 12 are fixed to the bottom surface of the base plate 1. The supports 12 can fix and support the entire device.

[0023] In use, pull the handle 36 away from the support plate 2, causing the movable plate 3 to move away from the support plate 2. This causes the limiting block 31 to compress the spring 41. Then, place the diamond grinding wheel 8 between the support plate 2 and the movable plate 3. Rotate the turntable 76, which drives the worm gear 74 to rotate around its own axis via the connecting rod 75. This allows the worm wheel 73, which meshes with the worm gear 74, to drive the double-acting screw 71 to rotate, thereby causing the two movable blocks 72 to move closer or further apart. This, in turn, causes the two limiting plates 6 to move closer or further apart, thus restricting the diamond grinding wheel 8 to the central axis of the base plate 1. Then, release the handle 36. The spring 41 will naturally rebound and compress the movable plate 3. When the moving plate 3 is in motion, the two sides of the diamond grinding wheel 8 will be in close contact with the support plate 2 and the moving plate 3 respectively. The diameter of the diamond grinding wheel 8 can be determined by the position of the first pointer 331 on the first scale line 321. Then, the rotating disk 55 is rotated, which drives the screw 54 to rotate around its own axis, thereby driving the slider 5 to move down along the central axis of the moving plate 3. This causes the pressure plate 51 and the fixed block 52 to move down synchronously, so that the bottom surface of the pressure plate 51 is in close contact with the top surface of the diamond grinding wheel 8. The thickness of the diamond grinding wheel 8 can be determined by the position of the second pointer 53 on the second scale line 34. In this way, the size detection operation of the diamond grinding wheel 8 is realized.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
