[0002] In the machining industry, the traditional clamping methods for the clamping of rotating parts are mostly three-jaw chucks or vises. However, as product requirements become higher and higher, and the demand for product quantity increases, these two clamping methods are obviously not suitable for mass production of high-demand parts. For parts that need to be mass-produced, the impact of processing efficiency on cost is crucial. The processing efficiency depends largely on the design of the fixture. A good fixture should not only be able to ensure the processing accuracy of the product, but also be easy and quick to disassemble and save time for clamping.

[0003] When using a three-jaw chuck and a vise for clamping, the clamping force is relatively concentrated, which can easily cause deformation or damage to the workpiece, affecting the size and surface effect of the workpiece. In addition, these two clamping methods have low clamping accuracy, can only process one product at a time, and cannot achieve repeated clamping and precise positioning, which increases the time for measurement and alignment.

[0029] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0030] In the description of this application, it should be noted that the terms "inside", "outside", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the product of the application is usually placed when in use, which is only for the convenience of describing this application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application. In addition, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0031] In the description of this application, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "disposed" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0032] The mass production clamping tooling for rotating parts in this application is mainly used in the processing of rotating parts, and is specifically used in the clamping angle of parts. By perfecting and adjusting the structure, the defects of traditional tooling and fixtures in clamping parts at different angles are improved.

[0033] See also Figure 1 , and combined with Figure 2-Figure 7 The mass production clamping tooling for rotating parts in this application has a main structure including a base plate 1 and a pressure plate 3. The part 2 is fixed on the base plate 1 and the part 2 is pressed and fixed by the pressure plate 3 to change the clamping state of the original part 2.

[0034] The base plate 1 is provided with a mounting hole 11 for mounting the part 2 , so that the part 2 can be detachably mounted on the base plate 1 , and the part 2 can be fixed on the base plate 1 by pressing the pressing plate 3 on the part 2 .

[0035] By avoiding the processing part of the part 2 by the pressing plate 3, the processing part of the part 2 can be exposed to the bottom plate 1, reducing the influence of the clamping process on the processing of the part 2.

[0036] The bottom plate 1 is provided with a positioning clamping portion for positioning and clamping the pressing plate 3 , so that the pressing plate 3 can be positioned and pressed on the mounting hole 11 , and the part 2 can be pressed and fixed at the same time.

[0037] The utility model can install the part 2 on the base plate 1 by arranging the base plate 1 and arranging the mounting holes 11 for the part 2 to be installed on the base plate 1, thereby ensuring the installation accuracy and reducing the time for measuring and aligning the part 2.

[0038] Combined with the press-fitting of part 2 by the pressure plate 3, the clamping form of the rotating part 2 can be improved, and the direct clamping of part 2 by the traditional clamping structure can be replaced by the positioning press-fitting form, thereby avoiding the clamping damage to part 2 caused by traditional clamping and avoiding the risk of deformation of part 2 due to concentrated clamping force.

[0039] The positioning clamping portion can be clamped and matched with the pressing plate 3, thereby improving the clamping accuracy and realizing repeated clamping and precise positioning.

[0040] In one specific embodiment, the mounting hole 11 includes a mounting countersunk hole, which is arranged on the top surface of the base plate 1, so that the part 2 can lie in the mounting countersunk hole from the top of the base plate 1 downward. The setting position of the mounting countersunk hole on the base plate 1 can be set according to the azimuth coordinates of the processing device, so that the measurement and alignment process can be reduced by directly placing the part 2 in the mounting countersunk hole.

[0041] The part 2 in the utility model comprises a mounting base 21 and a processing column 22. By seating the mounting base 21 in the mounting countersunk hole, the part 2 is mounted on the base plate 1 as a whole, and the processing column 22 is subsequently processed.

[0042] The pressing plate 3 is provided with a through hole 31 for the processing column 22 to pass through, so that the processing column 22 can protrude from the bottom plate 1 and the pressing plate 3, thereby effectively avoiding the processing part of the pressing plate 3.

[0043] In order to enable the part 2 to be detachably accommodated and installed on the base plate 1, the mounting base 21 is clearance-matched with the mounting countersunk hole. At the same time, in order to allow the pressure plate 3 to be separated from the part 2, the processing column 22 is clearance-matched with the through hole 31. Through this setting, repeated clamping of the part 2 on the clamping tooling can be achieved.

[0044] In order to ensure that the pressing plate 3 can press the part 2 stably and reliably, the pressing plate 3 in this embodiment includes a pressing plate. Preferably, the shape and size of the mounting hole 11 can be specifically processed and set according to the shape and size of the part 2. At the same time, the depth of the mounting countersunk hole is less than the height of the mounting base 21 of the part 2. Preferably, the depth of the mounting countersunk hole is 0.1-0.2mm less than the height of the mounting base 21. When the part 2 is installed into the mounting hole 11, the top surface of the mounting base 21 protrudes from the top surface of the base plate 1, so that the pressing plate 3 can press and tighten the part 2.

[0045] By pressing the part 2 with a pressing plate, the bottom surface of the pressing plate can be made higher than the top surface of the base plate 1. Further, the bottom surface of the pressing plate forms an effective pressing relationship with the top surface of the mounting base 21, thereby ensuring the reliability of the pressing of the part 2.

[0046] From the perspective of enabling the pressure plate 3 to be quickly positioned, a positioning groove 32 is provided on the edge of the press-fitting plate, and the positioning groove 32 is engaged with the positioning clamping part. Specifically, the positioning clamping part includes a positioning protrusion 12, and the positioning protrusion 12 is provided on the top surface of the base plate 1. Furthermore, the height of the positioning protrusion 12 is the same as the thickness of the press-fitting plate, which can facilitate the cooperation between the positioning protrusion 12 and the press-fitting plate.

[0047] In order to ensure that the pressure plate 3 can provide an effective pressing force, the pressure plate 3 needs to be fastened and installed on the base plate 1. Furthermore, the pressure plate 3 is detachably fixed to the base plate 1 by fastening screws, and a screw countersunk hole 13 is provided on the top surface of the base plate 1, and a connecting hole 33 for the fastening screw to pass through is provided on the pressure plate 3.

[0048] After the pressing plate 3 is positioned and clamped on the base plate 1, the tightening screws pass through the connecting holes 33 of the pressing plate 3 and are connected to the screw countersunk holes 13 of the base plate 1, which can provide effective tightening force, thereby converting the tightening force into a reliable press-fitting of the part 2.

[0049] Preferably, the screw countersunk holes 13 are evenly distributed on the circumferential periphery of the installation countersunk holes, and the connecting holes 33 are evenly distributed on the circumferential periphery of the through hole 31, and the positions of the screw countersunk holes 13 and the connecting holes 33 are relative to each other, which can provide relatively uniform fastening force, prevent stress concentration of the pressing force, and avoid the risk of deformation of the part 2.

[0050] It should be pointed out that the installation position of the positioning protrusion 12 on the base plate 1 is fixed, and the setting position of the positioning groove 32 on the pressure plate 3 is also fixed. Based on the matching and snap-fitting relationship between the two, by correspondingly determining the position of the screw countersunk hole 13 on the base plate 1 and the position of the connecting hole 33 on the pressure plate 3, the pressure plate 3 can be quickly installed on the base plate 1, so that the positions of the screw countersunk hole 13 and the connecting hole 33 are opposite to each other up and down, so that the screw connection operation can be directly performed, reducing the centering steps in the connection process.

[0051] Furthermore, based on the engagement between the positioning protrusion 12 and the positioning groove 32 , the rotation of the pressing plate 3 can be avoided when the fastening screw is screwed, thereby reducing the difficulty of operation.

[0052] With respect to the matching relationship between the positioning protrusion 12 and the positioning groove 32 , in order to ensure positioning accuracy, the positioning protrusion 12 is arranged on both sides of the mounting countersunk hole.

[0053] Further, the positioning groove 32 includes a notch groove, which is arranged on both sides of the through hole 31, and the edge of the notch groove matches the outer edge of the positioning protrusion 12. Preferably, the positioning protrusion 12 is a circular protrusion, and the notch groove is an arc-shaped notch groove. Through this arrangement, the positioning groove 32 in the form of a notch groove can be clamped on the outer edge of the positioning protrusion 12, thereby improving the convenience of positioning clamping.

[0054] There are multiple mounting holes 11, and the multiple mounting holes 11 are arranged in an array on the base plate 1, and the pressing plate 3, the mounting holes 11 and the parts 2 correspond to each other one by one.

[0055] In order to realize the mass production of rotating body parts 2, the utility model includes multiple mounting holes 11 on the same base plate 1, and the multiple mounting holes 11 are arranged in an array on the base plate 1. The pressure plate 3, the mounting holes 11 and the parts 2 correspond to each other one by one to form a clamping unit for a single part 2. At the same time, the corresponding dimensions of each part 2 and the dimensions of its related mounting holes 11 and the pressure plate 3 are all in the same form, ensuring that each part 2 can be clamped in the same state.

[0056] It should be noted that the pressing plate 3 in each clamping unit is fastened by means of a separate set of fastening screws, screw-connecting countersunk holes 13 and connecting holes 33 .

[0057] Adjacent mounting countersunk holes of different parts 2 can share the positioning protrusion 12, thereby reducing the number of positioning protrusions 12 and making the structure of the clamping tooling more concise.

[0058] The mass production clamping tooling for rotating body parts in the utility model cooperates with the mounting countersunk hole and the mounting base 21 of the part 2, and has high clamping accuracy, which ensures that the position will not change when the part 2 is repeatedly disassembled and assembled, eliminates the step of measuring and finding the origin on the machine, saves processing time, and achieves the purpose of accurate positioning during repeated clamping.

[0059] By using the pressing plate 3 and the fastening screws to fix the part 2, the press-fitting is more secure and the operation is simple and quick. Compared with the lateral force during clamping, the clamping method in the present application is more likely to protect the part 2 from being clamped or deformed.

[0060] The bottom plate 1 cooperates with the positioning protrusions 12 on both sides of the countersunk hole and the positioning grooves 32 on both sides of the pressing plate 3 to fix the position of the pressing plate 3, making it convenient to quickly find the position of the screw hole, and the pressing plate 3 will not rotate when the screw is screwed.

[0061] The clamping fixture in this application is a structural improvement specially made for mass production, and 20 workpieces can be processed in one clamping. Compared with traditional fixtures, it reduces the time for loading and unloading, improves processing efficiency, and reduces the labor intensity of workers.

[0062] It should be noted that the size and depth of the mounting countersunk hole on the tooling can be adjusted according to the dimensional characteristics of the required processed part 2 so that it matches the outer cylindrical surface of the required processed part 2, and parts 2 of various sizes can be clamped.

[0063] According to actual processing requirements, the number of countersunk holes installed on the base plate 1 can be increased or decreased, the shape of the pressure plate 3 and the position and size of the connecting hole 33 and / or the through hole 31 can be changed, and the square base plate 1 can also be set to a perfect circular shape to achieve the same technical effect.

[0064] The utility model also provides a mass production processing device for rotating body parts, including the above-mentioned mass production clamping tooling for rotating body parts, a base and a machine tool, the base is fixedly installed on the table of the machine tool, the bottom surface of the base plate 1 is provided with an assembly hole 14, the base is provided with a screw hole, and the assembly hole 14 is connected to the screw hole by a connecting bolt.

[0065] Specifically, the base in the present application is a quick-change base. First, the quick-change base is fixed on the table of the machine tool. Part 2 cooperates with the mounting countersunk hole on the base plate 1 through the outer cylindrical surface of the mounting base 21. The top is covered with a pressure plate 3, and then part 2 is tightened by locking the fastening screws.

[0066] Then, the quick-change base is connected to the base plate 1 by passing a special connecting bolt through the assembly hole 14 and the screw hole at the same time. The quick-change base is used because it is convenient for disassembly and assembly and can be accurately positioned.

[0067] The rotary body parts mass production processing device of the utility model can carry out mass production of rotary body parts 2, improve product quality, and reduce the product defect rate to a minimum.

[0068] It should be noted that, in the absence of conflict, the features in the embodiments of this application may be combined with each other.

[0069] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations.
