Description

Technical Field

[0001] The utility model relates to the technical field of machining, in particular to an auxiliary clamping device for a micro regulating valve body. Background Technique

[0002] The micro regulating valve is a valve widely used in the flow control of liquid media, and its main component is the micro regulating valve body. Existing micro regulating valve manufacturing and processing enterprises usually use three-axis CNC machine tools to manufacture and process the micro regulating valve body. When manufacturing and processing the micro regulating valve body with a polyhedron structure, in order to improve the manufacturing and processing efficiency of the micro regulating valve body, micro regulating valve manufacturing and processing enterprises usually develop and design corresponding clamping fixtures according to the shape and size of the micro regulating valve body to assist in manufacturing and processing, and then clamp the micro regulating valve body (that is, install and fix the micro regulating valve body in the clamping fixture), and then place the entire clamping fixture with the micro regulating valve body fixed into the CNC machine tool for manufacturing and processing, reducing the time for the CNC machine tool to replace the clamping fixture, improving the installation and fixation efficiency of the micro regulating valve body on the workbench of the CNC machine tool, so as to improve the production capacity of the micro regulating valve body and reduce the idle waiting time of the CNC machine tool. When the existing micro regulating valve body is installed and fixed in the clamping fixture, it is necessary for the operator to place the micro regulating valve body one by one at the prefabricated fixed position of the clamping fixture, and then fix it on the clamping fixture through the fixing component. It is found in the actual manufacturing and processing process that, because the micro regulating valve body is manually installed and fixed at the prefabricated fixed position of the clamping fixture, the following problems are likely to occur during the fixing process: First, because the operator performs manual installation and fixation, the proficiency and skill requirements for the operator are relatively high, increasing the requirements for the operator's skills and proficiency; Second, when manually fixing the micro regulating valve body at the prefabricated fixed position of the clamping fixture, it is necessary to manually position and adjust the position of the micro regulating valve body, and it takes a large amount of manpower to correct the position of the micro regulating valve body. When the correction is inaccurate, situations such as deviation, error, and insufficient alignment accuracy of the position of the micro regulating valve body after fixation are likely to occur, affecting the manufacturing and processing accuracy of the micro regulating valve body and the quality of the micro regulating valve body after manufacturing and processing, increasing the rejection rate of the micro regulating valve body after manufacturing and processing, and causing problems such as high manufacturing and processing costs.

[0003] Therefore, it has become an urgent problem for micro regulating valve manufacturing and processing enterprises to conduct research and development on the problems in the manufacturing and processing process of the existing micro regulating valve body with a polyhedron structure, improve the accuracy and efficiency of clamping the micro regulating valve body, thereby improving the manufacturing and processing accuracy and quality of the micro regulating valve body, reducing the rejection rate of the micro regulating valve body during the processing process, and reducing the production cost.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts fall within the scope of protection of the present utility model.

[0027] As Figures 1 to 8 shown, a micro-adjusting valve body auxiliary clamping device includes an auxiliary positioning mechanism 1 for adjusting the clamping position of the micro-adjusting valve body and a clamping fixture 2 for clamping the micro-adjusting valve body. The auxiliary positioning mechanism 1 includes a base 3, a support plate 4 provided on the upper end surface of the base 3, a fixing plate 5 fixed on the upper end surface of the support plate 4, a lifting assembly 6 fixed above the fixing plate 5, a positioning and adjusting assembly 7 fixed on the inner side wall of the support plate 4 and fixedly connected to the lifting assembly 6, and a guiding assembly 8 for precisely controlling the up and down movement direction of the positioning and adjusting assembly 7. In this embodiment, the micro-adjusting valve body is a cube structure; the base 3 is a cuboid structure, and two positioning guide posts 31 for positioning and fixing the clamping fixture 2 are provided on the base 3, and the positioning guide posts 31 are on the same straight line; the support plate 4 is fixed above the base 3 and is located inside the long side of the upper end surface of the base 3; the fixing plate 5 is fixedly connected to the top of the support plate 4, and a through hole for the output end of the lifting assembly 6 to pass through is provided on the fixing plate 5; the lifting assembly 6 is fixed above the fixing plate 5, the lifting assembly 6 is a cylinder, and the output end of the cylinder passes through the through hole on the fixing plate 5 and is fixedly connected to the upper end surface of the positioning and adjusting assembly 7, and the up and down movement of the positioning and adjusting assembly 7 is driven by the expansion and contraction of the output end of the cylinder.

[0028] As Figures 1 to 5As shown, the positioning and adjusting assembly 7 includes a cantilever plate 71 and adjusting parts 72 respectively arranged at both ends of the bottom of the cantilever plate 71. The upper end surface of the cantilever plate 71 is fixedly connected to the end of the output end of the cylinder. The adjusting part 72 includes two relatively arranged L-shaped claws 721 and a claw insert 722 arranged on the L-shaped claw 721. The L-shaped claw 721 is composed of a horizontal bottom plate 21 and a vertical side plate, and the L-shaped claw 721 is an integrally formed structure. The outer side wall of the horizontal bottom plate 21 is fixedly connected to the bottom of the cantilever plate 71, and the inner side walls of the vertical side plates of the two L-shaped claws 721 located on the same side of the cantilever plate 71 are relatively arranged. The claw insert 722 is arranged on the inner side of the vertical side plate of the L-shaped claw 721. A spring 723 and claw insert needles 724 arranged on both sides of the spring 723 are provided on the side wall of the claw insert 722 close to the vertical side plate. A spring connection hole matching the spring 723 and a needle connection hole matching the claw insert needle 724 are provided on the inner side wall of the vertical side plate of the L-shaped claw 721. One end of the spring 723 is connected to the side wall of the claw insert 722, and the other end is fixedly connected to the bottom of the spring connection hole. The claw insert needle 724 is movably connected to the needle connection hole, and the end of the claw insert needle 724 is fixedly connected to the side wall of the claw insert 722. In this embodiment, the cantilever plate 71 is of a concave structure, and the adjusting parts 72 are respectively arranged below the long sides on both sides of the "concave" of the cantilever plate 71. The claw insert 722 is of a prism structure, and the opposite sides of the claw inserts 722 on the two L-shaped claws 721 on the same side are vertical surfaces, and both the upper and lower sides of the vertical surfaces are inclined surfaces sloping backward. By connecting the L-shaped claw 721 and the claw insert 722 through the spring 723 and the claw insert needles 724, the claw insert 722 has a certain amount of movement space, which can better adjust the position and angle of the micro-valve body on the clamping fixture 2. By clamping the micro-valve body with the vertical surfaces of the two claw inserts 722, the micro-valve body is positioned correctly under the action of the two vertical surfaces.

[0029] As Figure 1 and Figure 3As shown in the figure, the guiding component 8 includes a guide rail 81 provided on the inner side wall of the support plate 4 and a sliding groove 82 provided on the side wall of the cantilever plate 71 close to the support plate 4 and adapted to the guide rail 81. The number of the guide rails 81 is more than two, and the number of the sliding grooves 82 is the same as that of the guide rails 81. The guide rail 81 and the sliding groove 82 are movably connected, so that the cantilever plate 71 can move up and down along the guide rail 81, and the positioning and adjusting component 7 will not shift during the up and down movement, improving the accuracy of the position and angle adjustment of the micro regulating valve body. In this embodiment, the number of the guide rails 81 and the sliding grooves 82 is both two. The two sliding grooves 82 are respectively located at the left and right ends of the side wall of the cantilever plate 71 close to the support plate 4, and the positions of the guide rails 81 on the support plate 4 correspond to the positions of the sliding grooves 82.

[0030] As Figures 6 to 8As shown, the clamping fixture 2 includes a bottom plate 21 and a plurality of pressing blocks 22 detachably fixed on the bottom plate 21 for fixing the micro-regulating valve body. A positioning through hole 211 corresponding to the size and position of the positioning guide post 31 is provided at the bottom of the bottom plate 21. The clamping fixture 2 is accurately positioned above the base 3 by the interaction between the positioning through hole 211 on the bottom plate 21 and the positioning guide post 31 on the base 3. On the upper end surface of the bottom plate 21, there are provided more than two micro-regulating valve body positioning blocks 212 for clamping and positioning the micro-regulating valve body, pressing block fixing holes 213 and pressing block positioning components 214 arranged on both sides of the micro-regulating valve body positioning blocks 212, and a plurality of limit pin nails 215 for restricting the position of the micro-regulating valve body. The pressing block positioning component 214 is composed of two pressing block positioning posts 2141 with the same structure, and the two pressing block positioning posts 2141 are symmetrically arranged with the middle part of the pressing block fixing hole 213 as the axis of symmetry. The micro-regulating valve body positioning blocks 212 are arranged at the top of the bottom plate 21. A protective gasket is provided above the micro-regulating valve body positioning blocks 212. The micro-regulating valve body is placed above the micro-regulating valve body positioning blocks 212, so that the micro-regulating valve body is clamped on the clamping fixture 2. In this embodiment, both the micro-regulating valve body positioning blocks 212 and the protective gasket are circular structures, and the number of the micro-regulating valve body positioning blocks 212 is two, and the positions of the two micro-regulating valve body positioning blocks 212 respectively correspond to the positions of the two adjusting parts 72. The limit pin nails 215 are arranged on both sides of the pressing block positioning blocks 212. In this embodiment, the number of the limit pin nails 215 is eight, and two limit pin nails 215 are provided on both sides of the pressing block positioning blocks 212. At the bottom of the pressing block 22, there are provided pressing block positioning holes 221 adapted to the pressing block positioning posts 2141 and pressing block through holes 222 communicating the upper and lower surfaces of the pressing block 22. The number of the pressing block positioning holes 221 is the same as the number of the pressing block positioning posts 2141 in one pressing block positioning component 214, and the positions correspond one by one. The size of the pressing block through holes 222 is the same as the size of the pressing block fixing holes 213, and the pressing block through holes 222 and the pressing block fixing holes 213 are connected by bolts to fix the pressing block 22 on the bottom plate 21. In the embodiment, the number of the pressing block positioning holes 221 is two. By the interaction between the pressing block positioning holes 221 and the pressing block positioning posts 2141, the pressing block 22 can be accurately fixed on the bottom plate 21. The pressing block 22 is of an inverted "L" shape structure. Pressing block gaskets for preventing the micro-regulating valve body from being scratched are provided at the included angle of the pressing block 22 and on the horizontal bottom surface for pressing the micro-regulating valve body. The pressing block gaskets can also increase the friction between the micro-regulating valve body and the pressing block 22, making the fixation of the micro-regulating valve body more firm. Both the protective gasket and the pressing block gasket are made of elastic materials. In this embodiment, both the protective gasket and the pressing block gasket are rubber blocks.

[0031] The general working process of the present utility model is as follows: Place the two micro-regulating valve bodies above the two micro-regulating valve body positioning blocks 212 of the clamping fixture 2 respectively. The position of the micro-regulating valve body can be roughly determined by the micro-regulating valve body positioning blocks 212 and the limit pins 215. At this time, connect the pressing block 22 to the clamping fixture 2 with screws but do not tighten and fix them; for the convenience of clamping the micro-regulating valve body, there is no perfect fit between the micro-regulating valve body and the limit posts, so there are certain deviations between the actual fixed angle and position of the micro-regulating valve body on the clamping fixture and the preset angle and position, and further adjustment is required. Insert the positioning through holes 211 on the clamping fixture 2 into the positioning guide posts 31 of the base 3 so that the clamping fixture 2 can be accurately fixed on the base 3; then supply air to the cylinder, and the output end of the cylinder moves downward, driving the positioning adjustment assembly 7 to move downward along the guide rail 81. Under the action of the guide rail 81, the positioning adjustment assembly 7 will not shift during the descending process; during the gradual downward movement of the positioning adjustment assembly 7, the micro-regulating valve body will be clamped by the jaw inserts 722 on the two L-shaped jaws 721. Since the surface of the jaw insert 722 in contact with the micro-regulating valve body is perpendicular to the horizontal plane, the two vertical surfaces clamp the micro-regulating valve body to adjust the position and angle of the micro-regulating valve body. Then tighten the bolt in the pressing block through hole 222 to connect the pressing block through hole 222 and the pressing block fixing hole 213, so that the pressing block 22 presses the micro-regulating valve body to fix it; finally, after the output end of the cylinder rises to drive the positioning adjustment assembly 7 to separate from the micro-regulating valve body, remove the clamping fixture 2 from the base 3 to complete the adjustment of the position and angle of the micro-regulating valve body on the clamping fixture 2, and then assemble the clamping fixture 2 into the fixture in the numerical control machine tool to complete the processing and manufacturing of the micro-regulating valve body. The present utility model clamps the micro-regulating valve body by the jaw inserts 722 on the two L-shaped jaws 721 to adjust the angle and position of the micro-regulating valve body, reducing the time spent by the operator on adjusting and calibrating the position and angle of the micro-regulating valve body, reducing the operation difficulty and the requirements for the operator's technology and proficiency, improving the accuracy of positioning the micro-regulating valve body, and thus improving the processing precision of the micro-regulating valve body.

[0032] The above is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of various equivalent modifications or substitutions, and these modifications or substitutions should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the claims.
