Description

Technical Field

[0001] This application relates to the field of crescent-shaped auxiliary plate product size measurement technology, specifically to a contouring auxiliary tooling for measuring the size of crescent-shaped auxiliary plates. Background Technology

[0002] In an internal gear pump, the crescent plate is located between the two end faces of the gears. It usually maintains a small gap with the driving gear and the driven gear, which can separate the high and low pressure oil chambers, thereby preventing the oil in the high pressure oil chamber from flowing directly into the low pressure oil chamber and ensuring the smooth operation of the oil pump.

[0003] In addition to the crescent-shaped plate, internal gear pumps may also be equipped with a crescent-shaped auxiliary plate. The auxiliary plate is typically located on the outside of the crescent-shaped plate, and its function is to further enhance the sealing effect and reduce leakage. Simultaneously, the auxiliary plate also serves to support and position the crescent-shaped plate, ensuring its stability during operation.

[0004] Currently, when measuring the dimensions of crescent-shaped auxiliary plates, the product is usually clamped by a three-jaw chuck. Because the product wall thickness is thin and the tolerance zone is small, this measurement method has a high probability of deforming the product during clamping, resulting in distorted measurement results. Summary of the Invention

[0005] This application provides a contouring auxiliary tooling for measuring the dimensions of a crescent-shaped auxiliary plate. This tooling is used for measuring the dimensions of crescent-shaped auxiliary plate products and can avoid the problem of the crescent-shaped auxiliary plate being deformed during clamping, which would lead to distorted measurement results.

[0006] This application provides a contouring auxiliary tooling for measuring the size of a crescent-shaped subplate, comprising: a flat-jaw vise, which includes a fixed jaw and a movable jaw, which are arranged opposite to each other. The movable jaw can move relative to the fixed jaw to change the gap between them; a first contouring block and a second contouring block, both located within the gap. The first contouring block and the second contouring block are detachably mounted on the inner surfaces of the fixed jaw and the movable jaw, respectively, and the first contouring block and the second contouring block contour-clamp the crescent-shaped subplate.

[0007] In some embodiments, the flat jaw pliers further includes a base located on the bottom surface of the first and second contour blocks. One end of the base is provided with the fixed jaw, and the other end is provided with a fixing block. The fixing block is equipped with a moving structure for driving the moving jaw to move relative to the fixed jaw.

[0008] In some embodiments, the movable structure is a lead screw bolt, whose threads pass through the fixed block of the base, and whose end is fixedly connected to the outer side of the movable jaw.

[0009] In some embodiments, the outer surfaces of the first and second contour blocks are provided with a first mounting groove, which is used to fit into the fixed jaw or the moving jaw.

[0010] In some embodiments, the first mounting groove is a rectangular opening groove that penetrates the top and bottom surfaces of the contour block.

[0011] In some embodiments, the sidewall of the first mounting groove is provided with at least one threaded through hole for mounting with a fixed jaw or a movable jaw via a screw.

[0012] In some embodiments, when there is only one threaded through hole, the threaded through hole is located at the center of the sidewall of the first mounting groove.

[0013] In some embodiments, the inner surfaces of the first and second contour blocks are provided with second mounting grooves, and a pair of clamping blocks for contour clamping the crescent-shaped subplate are provided in the two second mounting grooves.

[0014] In some embodiments, the second mounting groove is a rectangular opening groove that penetrates the top surface of the contour block.

[0015] In some embodiments, the bottom wall of the second mounting groove is provided with a plurality of threaded blind holes, and the clamping block and the contour block are connected by studs.

[0016] The beneficial effects of the technical solutions provided in this application include:

[0017] When measuring the crescent-shaped auxiliary plate, correctly place it between the first and second contour blocks. Move the jaws manually or mechanically to gradually bring the first contour block closer to the second contour block mounted on the fixed jaws, until the first and second contour blocks clamp the crescent-shaped auxiliary plate. This ensures that the crescent-shaped auxiliary plate is not deformed, resulting in more accurate measurements.

[0018] After the crescent-shaped auxiliary plate is measured, move the moving jaws in the opposite direction by hand or mechanical means to gradually move the first profiling block away from the second profiling block installed in the fixed jaws until the crescent-shaped auxiliary plate is released and removed.

[0019] By setting the fixed jaws and the moving jaws relative to each other, the moving jaws can move relative to the fixed jaws to change the gap between them. This allows for quick adjustment of the jaw spacing to accommodate crescent-shaped sub-boards of different sizes.

[0020] By detachably installing the first and second contour blocks on the inner sides of the fixed and moving jaws respectively, technicians can quickly replace the corresponding contour blocks when faced with measurement tasks of crescent-shaped subplates of different shapes. This avoids the tedious process of complex modification of the entire jaw or remaking tooling when processing workpieces of different shapes using traditional fixed-structure flat jaw vises.

[0021] By setting the first and second contour blocks to be able to contour-clamp the crescent-shaped subplate, it means that during the clamping process, the contour blocks and the crescent-shaped subplate have a very high degree of fit, avoiding the problem of the crescent-shaped subplate being deformed by clamping, which would lead to the distortion of measurement results.

[0030] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.

[0031] A flat-jaw vise, also known as a machine vise, is a general-purpose clamping tool commonly used for mounting small workpieces. It is a standard accessory for milling machines and drilling machines, and is fixed to the machine tool's worktable to hold the workpiece for cutting and machining.

[0032] This application provides a contouring auxiliary tooling for measuring the size of a crescent-shaped auxiliary plate, which can avoid the problem of the crescent-shaped auxiliary plate being deformed during clamping, resulting in distorted measurement results.

[0033] See Figure 1 , Figure 1 This is a schematic diagram of the contouring auxiliary tooling used for measuring the dimensions of the crescent-shaped secondary plate in an embodiment of this application. For example... Figure 1 As shown, in one embodiment, the contouring auxiliary fixture includes a flat-jaw vise 1, a first contouring block 2, and a second contouring block 3. The flat-jaw vise 1 includes a fixed jaw 11 and a movable jaw 12, which are positioned opposite each other. The movable jaw 12 can move relative to the fixed jaw 11 to change the gap between them. In the prior art, the flat-jaw vise 1 is a relatively conventional general-purpose fixture. Due to its simple composition, compact structure, and ability to easily adjust the gap and clamping position between the movable jaw 12 and the fixed jaw 11, it is suitable for installing some small workpieces. However, the flat-jaw vise 1 also has a drawback: the clamping surfaces of the movable jaw 12 and the fixed jaw 11 are mostly flat. Directly using the flat-jaw vise 1 to clamp the crescent-shaped sub-plate will also deform the crescent-shaped sub-plate, resulting in distorted measurement results.

[0034] Therefore, this embodiment is actually an improvement on the flat-jaw pliers 1, specifically, the first contour block 2 and the second contour block 3 are detachably installed within the aforementioned gap. For example... Figure 1As shown, the first contour block 2 is detachably mounted on the inner side of the movable jaw 12, and the second contour block 3 is detachably mounted on the inner side of the fixed jaw 11. The first contour block 2 and the second contour block 3 contour-clamp the crescent-shaped sub-plate. At this time, the first contour block 2 and the second contour block 3 respectively contour-clamp the opposite surfaces of the crescent-shaped sub-plate, and the clamping surfaces of the first contour block 2 and the second contour block 3 correspond in shape and contour to the clamped surface of the crescent-shaped sub-plate. The crescent-shaped sub-plate can be an arc-shaped plate, and the clamped surfaces of the crescent-shaped sub-plate are all arc-shaped surfaces. Therefore, the clamping surfaces of the first contour block 2 and the first contour block 3 are also arc-shaped surfaces. The gap between the movable jaw 12 and the fixed jaw 11 can be adjusted by simply operating the moving structure 14 of the movable jaw 12 (such as a lead screw). Furthermore, the moving trajectory of the movable jaw 12 is a linear motion.

[0035] In this embodiment, when measuring the crescent-shaped subplate, the crescent-shaped subplate is correctly placed between the first contour block 2 and the second contour block 3. By manually or mechanically moving the jaws 12, the first contour block 2 is gradually moved closer to the second contour block 3 mounted on the fixed jaws 11 until the first contour block 2 and the second contour block 3 clamp the crescent-shaped subplate. This ensures that the crescent-shaped subplate is not deformed by clamping, resulting in more accurate measurement results.

[0036] After the crescent-shaped auxiliary plate is measured, the moving jaw 12 is moved in the opposite direction by hand or mechanical means, which drives the first profiling block 2 to gradually move away from the second profiling block 3 installed in the fixed jaw 11 until the crescent-shaped auxiliary plate is released and removed.

[0037] By setting the fixed jaw 11 and the movable jaw 12 opposite to each other, the movable jaw 12 can move relative to the fixed jaw 11 to change the gap between them. This allows for quick adjustment of the jaw spacing to accommodate crescent-shaped sub-boards of different sizes.

[0038] By detachably installing the first contour block 2 and the second contour block 3 on the inner sides of the fixed jaw 11 and the movable jaw 12 respectively, technicians can quickly replace the corresponding contour block (i.e., the first contour block 2 or the second contour block 3) when facing measurement tasks of crescent-shaped subplates of different shapes. This avoids the tedious process of complex modification of the entire jaw or remaking tooling when processing workpieces of different shapes using traditional fixed-structure flat jaw vises 1.

[0039] By setting the first contour block 2 and the second contour block 3 to be able to contour and clamp the crescent-shaped subplate, it means that the contour block and the crescent-shaped subplate have a very high degree of fit during the clamping process, avoiding the problem of the crescent-shaped subplate being deformed by clamping, which would lead to the distortion of measurement results.

[0040] Furthermore, in one embodiment, such as Figure 1As shown, the flat-jaw pliers 1 also includes a base 13 located on the bottom surface of the first contour block 2 and the second contour block 3. One end of the base 13 has a fixed jaw 11, and the other end has a fixed block 131. The fixed block 131 is equipped with a moving structure 14 for moving the movable jaw 12 relative to the fixed jaw 11. In this embodiment, the flat-jaw pliers 1 also includes a base 13 located on the bottom surface of the first contour block 2 and the second contour block 3. One end of the base 13 has a fixed jaw 11, and the other end has a fixedly mounted moving structure 14 for moving the movable jaw 12 relative to the fixed jaw 11. The base 13 is not only a basic support component for the first contour block 2 and the second contour block 3, but also provides a stable mounting platform for the entire flat-jaw pliers 1. By installing the moving structure 14 on the fixed block 131 for moving the movable jaw 12 relative to the fixed jaw 11, the movable jaw 12 can be moved relative to the fixed jaw 11, thereby moving the first contour block 2 closer to the second contour block 3 mounted on the fixed jaw 11. This allows for flexible adjustment according to crescent-shaped auxiliary plates of different sizes. The movable jaw 12 drives the first contour block 2 to move in a straight line on the base 13. The base 13 can be connected to the fixed jaw 11 and the fixed block 131 separately or as a single unit. A single unit connection makes the overall structure of the flat-jaw pliers 1 more compact and occupies less space. At the same time, this structure can reasonably distribute the force, enhancing the overall strength and rigidity of the flat-jaw pliers 1, making it less prone to damage during long-term use and exhibiting high reliability and durability.

[0041] Furthermore, in one embodiment, such as Figure 1 As shown, the movable structure 14 is a lead screw bolt, whose thread passes through the fixing block 131 of the base 13, and its end is fixedly connected to the outer side of the movable jaw 12. In this embodiment, the movable structure 14 is a lead screw bolt, which means that the linear motion of the movable jaw 12 is converted from helical motion. By passing the lead screw bolt thread through the fixing block 131 of the base 13 and fixing its end to the outer side of the movable jaw 12, when the lead screw bolt rotates, the movable jaw 12 will make a precise linear motion along the axial direction of the lead screw bolt. Since the thread pitch is fixed and precise, the moving distance of the movable jaw 12 can be precisely controlled by controlling the rotation angle and number of turns of the lead screw bolt, thereby achieving precise clamping of crescent-shaped auxiliary plates of different sizes.

[0042] Furthermore, in one embodiment, see... Figure 2 , Figure 2 for Figure 1 A schematic diagram showing the interaction between the first contour block 2 and the second contour block 3. (See diagram below.) Figure 2As shown, both the first contour block 2 and the second contour block 3 have a first mounting groove 21 on their outer surfaces. The first mounting groove 21 is used to fit into the fixed jaw 11 or the movable jaw 12. In this embodiment, the "outer surface" is actually the mounting surface of the first contour block 2 and the movable jaw 12, or the mounting surface of the second contour block 3 and the fixed jaw 11. The shape of the "first mounting groove 21" is not defined, but it must ensure that the contour block can be detachably mounted on the fixed jaw 11 or the movable jaw 12. The contour block is fitted into the fixed jaw 11 or the movable jaw 12 through the first mounting groove 21, making the connection between the contour block and the fixed jaw 11 or the movable jaw 12 tighter and more stable. At the same time, contour blocks of different shapes or sizes can be selected to be installed according to the different shapes or sizes of crescent-shaped auxiliary plates, increasing the adaptability of the contouring auxiliary tooling to the clamping of different types of crescent-shaped auxiliary plates and improving the versatility of the contouring auxiliary tooling.

[0043] Furthermore, in one embodiment, see... Figure 3 , Figure 3 for Figure 2 A schematic diagram of the first contour block 2 (without clamping block 23). Figure 3 As shown, the first mounting groove 21 is a rectangular opening that penetrates the top and bottom surfaces of the profiling block. In this embodiment, through the above technical solution, during installation, the profiling block can be aligned with the corresponding parts of the fixed jaw 11 or the movable jaw 12 from the top or bottom surface, providing ample operating space and reducing installation difficulty. During disassembly, the profiling block can be removed by applying force from two directions, making it convenient and quick, and improving work efficiency. Simultaneously, this through-type design makes the profiling block less prone to shaking or displacement under external forces after installation, thereby improving stability during the measurement process.

[0044] Furthermore, in one embodiment, such as Figure 3 As shown, the side wall of the first mounting groove 21 has at least one threaded through hole 211 for mounting to the fixed jaw 11 or the movable jaw 12 via a screw 212. In this embodiment, by providing at least one threaded through hole 211 for mounting to the fixed jaw 11 or the movable jaw 12 via a screw 212 on the side wall of the first mounting groove 21, a strong clamping force can be provided to tightly connect the contour block to the fixed jaw 11 or the movable jaw 12, improving the installation accuracy of the contour block and thus ensuring the clamping accuracy and machining accuracy of the workpiece. In addition, multiple threaded through holes 211 can be reasonably provided on the side wall of the first mounting groove 21 according to the size and shape of the contour block, so as to select different installation positions and methods, enhancing the adaptability of the contour block to the fixed jaw 11 or the movable jaw 12, and improving the versatility and flexibility of the fixed jaw 11 or the movable jaw 12.

[0045] Furthermore, in one embodiment, such as Figure 3As shown, when there is only one threaded through hole 211, the threaded through hole 211 is located at the center of the side wall of the first mounting groove 21. In this embodiment, when there is only one threaded through hole 211, by setting the threaded through hole 211 at the center of the side wall of the first mounting groove 21, the screw 212 can form a symmetrical force between the contour block and the fixed jaw 11 or the movable jaw 12 after installation, ensuring a tighter and flatter fit between the contour block and the fixed jaw 11 or the movable jaw 12, providing more stable support and positioning. In addition, since the threaded through hole 211 is located at the center of the side wall of the first mounting groove 21, when it is necessary to fine-tune the installation position of the contour block, the screw 212 can be rotated evenly to achieve a slight movement of the contour block in the horizontal and vertical directions, so as to achieve the optimal installation position and angle, thereby better adapting to the clamping requirements of crescent-shaped auxiliary plates of different sizes.

[0046] Furthermore, in one embodiment, such as Figure 3 As shown, the inner surfaces of the first contour block 2 and the second contour block 3 are each provided with a second mounting groove 22. A pair of clamping blocks 23 for contour clamping the crescent-shaped sub-plate are provided within the two second mounting grooves 22. In this embodiment, the "pair of clamping blocks 23" are used to contour clamp the crescent-shaped sub-plate, and the clamping surface of each clamping block 23 corresponds to the two clamped surfaces of the crescent-shaped sub-plate. Therefore, if the two clamped surfaces of the crescent-shaped sub-plate are different, there will also be differences between the clamping blocks 23. By providing second mounting grooves 22 on the inner surfaces of the first contour block 2 and the second contour block 3, and providing a pair of clamping blocks 23 for contour clamping the crescent-shaped sub-plate within the two second mounting grooves 22, it is ensured that the two clamping blocks 23 can accurately contour clamp the crescent-shaped sub-plate and provide a uniform and stable clamping force.

[0047] Furthermore, when the contour block wears down and can no longer accurately contour and clamp the crescent-shaped subplate, it can be replaced with a new clamping block 23, which greatly reduces the maintenance cost of the equipment and improves resource utilization efficiency.

[0048] Furthermore, in one embodiment, such as Figure 3 As shown, the second mounting slot 22 is a rectangular opening that penetrates the top surface of the contour block. In this embodiment, using the above technical solution, the clamping block 23 can be directly placed into the second mounting slot 22 from the top surface of the contour block, reducing the installation difficulty. Furthermore, if problems such as improper installation of the clamping block 23 are found, adjustments can be made in a timely manner to ensure clamping accuracy. In addition, the rectangular opening slot provides stable support and positioning for the clamping block 23, making the fixation of the clamping block 23 within the slot more reliable.

[0049] Furthermore, in one embodiment, such as Figure 3As shown, the bottom wall of the second mounting groove 22 has multiple threaded blind holes 221, and the clamping block 23 is connected to the contour block by studs 222. In this embodiment, the bottom wall of the second mounting groove 22 has multiple threaded blind holes 221, for example, as... Figure 3 As shown, each second mounting slot 22 has two threaded blind holes 221 symmetrically arranged on its bottom wall. The clamping block 23 also has a threaded through hole 211 corresponding to the threaded blind hole 221. The stud 222 passes through the threaded through hole 211 of the clamping block 23 and the threaded blind hole 221 of the contour block, so that the clamping block 23 and the contour block can fit tightly together. When the crescent subplate is clamped in a contouring manner, no matter how much external force it is subjected to, the clamping block 23 is not easy to loosen or fall off, thus ensuring the stability of the clamping.
