TECHNICAL FIELD

[0002] In the tooling fixture technical field, the existing tooling fixture has certain limitations in the aspect of part machining clamping.
[0003] From the structure, part of tooling fixture structure is relatively simple, and the clamping and fixing mode of part is relatively single, and the position and connection relationship between the parts are usually designed around the single direction or fixed angle clamping of part. When fixing the part, the part is directly contacted and pressed by some conventional clamping parts such as simple clamping plate and jaw, to realize fixing. However, this fixing mode is often difficult to meet some complex processing requirements.
[0004] In the process, for part needing to process two end faces respectively, after fixing the part by the existing tooling fixture, the part cannot be directly turned over. This leads to that when the processing of one end face of the part is completed, the operator needs to take down the part from the tooling fixture, manually turns over the part, and then clamps and fixes the two sides of the part again. This process is not only inconvenient to operate, greatly consumes time and manpower, increases manual operation time and labor intensity, but also easily causes the position deviation of the part due to frequent complete dismounting and re-clamping of the whole part, and affects the precision of part processing and the consistency of product quality.
[0005] In summary, the existing tooling fixture has many deficiencies when facing the part needing double-sided processing, whether in the structural design or in the process operation process, it is difficult to efficiently and accurately meet the production requirements, and an advanced and convenient tooling fixture is needed to solve these problems.

[0030] Example 1
[0031] This embodiment provides a tooling fixture with a rotating clamping assembly. Please refer to [link / reference]. Figure 1 The assembly includes an assembly plate 1, on which a rotary clamping assembly 2 is mounted. The rotary clamping assembly 2 includes a fixed base 21, a rotating base 22, a first movable jaw 24, and a second movable jaw 25. The fixed base 21 is fixedly mounted on the assembly plate 1. One end of the rotating base 22 is rotatably fixed to the fixed base 21, and the other end (outer end, away from the fixed base 21) of the rotating base 22 is provided with a clamping plate 23, which is used to clamp one side of the part. During rotation, the rotating base 22 can oriented the clamping plate 23 towards one side or the other side of the fixed base 21. The first movable jaws 24 are spaced apart on one side of the fixed base 21, and the second movable jaws 25 are spaced apart on the other side of the fixed base 21. The first movable jaws 24 and the second movable jaws 25 are respectively adjustablely spaced relative to the fixed base 21 on the assembly plate 1, and are respectively used to clamp the other side of the part.
[0032] In this embodiment, the tooling fixture with a rotary clamping assembly forms a first clamping area between the first movable jaw 24 and the clamping plate 23 when the rotary seat 22 rotates to face the side of the fixed seat 21 (i.e., the side where the first movable jaw 24 is located). When the rotary seat 22 rotates to face the other side of the fixed seat 21 (i.e., the side where the second movable jaw 25 is located), a second clamping area is formed between the second movable jaw 25 and the clamping plate 23. The rotation of the rotary seat 22 enables the switching between the first and second clamping areas, facilitating the machining of the two end faces of the part.
[0033] In this embodiment, the tooling fixture with a rotating clamping assembly, during the actual clamping and processing of a part, clamps one side of the part to the clamping plate 23, and rotates the rotating base 22 so that the clamping plate 23 faces the side of the fixed base 21 (i.e., the side where the first moving jaw 24 is located). Then, the distance between the first moving jaw 24 and the fixed base 21 is adjusted so that the other side of the part is clamped on the first moving jaw 24, thereby clamping and fixing the part, and processing one end face of the part. After processing one end face of the part, the first moving jaw 24 is released to release the other side of the part. The part is flipped (i.e., turned over) by rotating the rotating base 22, and the clamping plate 23 faces the other side of the fixed base 21 (i.e., the side where the second moving jaw 25 is located). Then, the distance between the second moving jaw 25 and the fixed base 21 is adjusted so that the other side of the part is clamped on the second moving jaw 25, clamping and fixing the part again, thereby facilitating the processing of the other end face of the part. The tooling fixture with a rotating clamping assembly in this embodiment facilitates the flipping of parts, thereby accelerating the efficiency of part processing.
[0034] In this embodiment, please refer to Figures 1-3 The fixed base 21 is U-shaped and is fixedly mounted on the mounting plate 1 by bolts 214. Specifically, in this embodiment, the fixed base 21 includes a first fixing part 211 fixedly connected to the top surface of the mounting plate 1 by bolts 214, and a second fixing part 212 and a third fixing part 213 located at both ends of the first fixing part 211. In this embodiment, the rotating base 22 is U-shaped and rotatably mounted inside the fixed base 21. Specifically, the rotating base 22 includes a first rotating connecting part 221, and a second rotating connecting part 222 and a third rotating connecting part 223 located at both ends of the first rotating connecting part 221. The ends of the second rotating connecting parts 222 and the third rotating connecting parts 223 away from the first rotating connecting part 221 are rotatably fixedly connected to the inner sides of the ends of the second fixing parts 212 and the third fixing parts 213 away from the first fixing part 211, respectively, thereby rotatably mounting the rotating base 22 on the fixed base 21 and enabling it to rotate 180 degrees relative to the fixed base 21. Of course, the shape and connection method of the fixed seat 21 and the rotating seat 22 described above do not represent a limitation on the scope of implementation of this utility model. Those skilled in the art can also make conventional adjustments according to actual needs, so that one end of the rotating seat 22 can be rotatably set on the fixed seat 21.
[0035] In this embodiment, please refer to Figure 3 and Figure 4The clamping plate 23 includes a first clamping plate 231 and a second clamping plate 232. The distance between the first clamping plate 231 and the second clamping plate 232 is adjustable at the other end of the rotating seat 22. By adjusting the distance between the first clamping plate 231 and the second clamping plate 232, the workpiece can be clamped or released. During use, one side of the workpiece is inserted between the first clamping plate 231 and the second clamping plate 232, bringing the first clamping plate 231 and the second clamping plate 232 closer together (i.e., reducing the distance), clamping one side of the workpiece. When it is necessary to release the workpiece, the first clamping plate 231 and the second clamping plate 232 are moved away from each other, thus releasing one side of the workpiece.
[0036] Specifically, please refer to Figure 4The other end face of the rotary seat 22 (specifically, the outer side of the first rotary connecting part 221) is provided with a first sliding groove 224 and a second sliding groove 225 on both sides (i.e., the first sliding groove 224 is provided on one side of the end face and the second sliding groove 225 is provided on the other side of the end face), and the first sliding groove 224 and the second sliding groove 225 extend along both sides of the end face of the other end of the rotary seat 22. In this embodiment, there are two of each of the first sliding groove 224 and the second sliding groove 225. One end of the first clamping plate 231 and the second clamping plate 232 are slidably disposed in the first sliding groove 224 and the second sliding groove 225, respectively; the other end of the first clamping plate 231 and the second clamping plate 232 extend out of the end face of the other end of the rotary seat 22 (specifically, the outer side of the first rotary connecting part 221), so that one side of the part can be accommodated between the other ends of the first clamping plate 231 and the second clamping plate 232. In this embodiment, in order to adjust the distance between the first clamping plate 231 and the second clamping plate 232, a double-axis lead screw 226 is also provided at the other end of the rotating seat 22. The two ends of the double-axis lead screw 226 face the two sides of the rotating seat 22. Specifically, a double-axis lead screw groove 227 is also provided on the end face of the other end of the rotating seat 22 (specifically, the outer side of the first rotating connection part 221). The double-axis lead screw groove 227 extends along both sides on the end face of the other end of the rotating seat 22. The double-axis lead screw 226 is rotatably disposed in the double-axis lead screw groove 227, and one end of the double-axis lead screw 226 extends through one side of the rotating seat 22, thereby facilitating the rotation of the double-axis lead screw 226 by manual or electric drive. One end of the first clamping plate 231 and the second clamping plate 232 respectively extends into the dual-axis lead screw groove 227. The dual-axis lead screw 226 passes through one end of the first clamping plate 231 and the second clamping plate 232 respectively and is threadedly connected to one end of the first clamping plate 231 and the second clamping plate 232 respectively. The first clamping plate 231 and the second clamping plate 232 are located on two shafts with different helical directions on the dual-axis lead screw 226. With this configuration, by rotating the dual-axis lead screw 226, the first clamping plate 231 and the second clamping plate 232 can slide within the first sliding groove 224 and the second sliding groove 225 respectively, thereby facilitating the adjustment of the distance between the first clamping plate 231 and the second clamping plate 232, and making it convenient to clamp or release one side of the part.
[0037] In this embodiment, please refer to Figures 1-4 The rotary clamping assembly 2 also includes a flipping seat 26, which is fixedly mounted on the assembly plate 1 and located on the rotation center line of the rotary seat 22.

The flipping base 26 has a flipping groove 262 centered on the first flipping rod 261. A guide rod 263 is movably mounted within the flipping groove 262. The guide rod 263's movement trajectory within the flipping groove 262 forms a 180-degree flipping angle relative to the first flipping rod 261. The guide rod 263 and the first flipping rod 261 are fixedly connected by a second flipping rod 264. In this embodiment, the flipping groove 262 is an arc centered on the first flipping rod 261, with an included angle (central angle) of 180 degrees. By setting the above structure, and with the flipping groove 262 set in an arc shape with a 180-degree angle, the first flipping rod 261 can be driven to rotate by an external force, while the guide rod 263 moves within the flipping groove 262, so as to facilitate the 180-degree flipping of the rotating seat 22, thereby facilitating the 180-degree flipping of the parts.
[0038] In this embodiment, please refer to Figure 3 and Figure 4 The flipping groove 262 is located on the side (i.e., the outer side) of the flipping seat 26 away from the rotating seat 22. The other end of the first flipping rod 261 passes through the flipping seat 26, and the second flipping rod 264 is bent and connected to the other end of the first flipping rod 261. The guide rod 263 is fixed to the inner side of the second flipping rod 264 and extends into the flipping groove 262. By setting the above structure on the outer side of the flipping seat 26, it is convenient to drive the first flipping rod 261 or the second flipping rod 264 by manual or other means, so as to drive the rotating seat 22 to rotate.
[0039] In this embodiment, the flipping base 26 is also provided with two positioning holes 265, which are located on both sides of the first flipping rod 261, on a straight line between the two arc-shaped ends of the flipping groove 262 that form a 180-degree angle. A retractable positioning post 266 is also fixedly provided on the second flipping rod 264, which can be locked or unlocked in the positioning hole 265. After the flipping operation is completed, the retractable positioning post 266 can be inserted into and engaged in the positioning hole 265 to fix the flipped part, preventing it from flipping or shaking during processing. When it is necessary to release the flipping fixation, the retractable positioning post 266 can be removed from the positioning hole 265. The retractable positioning post 266 adopts a conventional technical structure in the art; please refer to [reference needed]. Figure 3 and Figure 4 For example, the conventional components of a telescopic positioning post 266 include positioning post 2661, first spring 2662, and positioning rod 2663, which will not be described in detail here.

Figure 1 The top surface of the assembly plate 1 has a third sliding groove 11 and a fourth sliding groove 12 respectively on both sides, and the third sliding groove 11 and the fourth sliding groove 12 extend along both sides of the top surface of the assembly plate 1. The fixing seat 21 is installed on the top surface of the assembly plate 1 between the third sliding groove 11 and the fourth sliding groove 12. The first movable gripper 24 and the second movable gripper 25 are slidably disposed in the third sliding groove 11 and the fourth sliding groove 12 respectively. Specifically, the movable connecting part 242 of the first movable gripper 24 and the movable connecting part 242 of the second movable gripper 25 are slidably disposed in the third sliding groove 11 and the fourth sliding groove 12 respectively.
[0042] In this embodiment, to further improve work efficiency, please refer to... Figure 5 and Figure 6The gripper portion 241 has a clamping plate 243 inside. The clamping plate 243 has a U-shaped cross-section, and the opening direction of the U-shape is the same as the opening direction of the U-shape of the gripper portion 241. The clamping plate 243 includes a first clamping plate 2431, and a second clamping plate 2432 and a third clamping plate 2433 located at both ends of the first clamping plate 2431, respectively. The outer sides of the second clamping plate 2432 and the third clamping plate 2433 are respectively provided with a first rack 2434 and a second rack 2434 extending along their respective ends. 435, the first rack 2434 and the second rack 2435 respectively mesh with the first rack 2414 and the second rack 2415; a stop bar 244 is fixedly provided on the outer side of the first clamping plate 2431, wherein one end of the stop bar 244 is fixedly connected to the outer side of the first clamping plate 2431, and the other end of the stop bar 244 slidably passes through the first gripper portion 2411 and extends out of the outer side of the first gripper portion 2411; a limit abutment portion 24 is provided on the other end of the stop bar 244. 41; A second spring 245 is sleeved on the abutment rod 244. The second spring 245 is located between the outer side of the first gripper portion 2411 and the limiting abutment portion 2441, and the two ends of the second spring 245 are fixedly connected to the outer side of the first gripper portion 2411 and the limiting abutment portion 2441, respectively. When the clamping plate 243 moves towards the inside of the gripper portion 241 relative to the gripper portion 241, the first rack 2434 and the second rack 2435 respectively drive the first rack. 2414 and the second rack 2415 rotate, respectively driving the first chuck 2418 and the second chuck 2419 to move towards each other to achieve clamping; when the clamping plate 243 moves towards the outside of the clamping jaw 241 relative to the jaw portion 241, the first rack 2434 and the second rack 2435 respectively drive the first rack 2414 and the second rack 2415 to rotate, respectively driving the first chuck 2418 and the second chuck 2419 to move away from each other to achieve opening.
[0043] When the first moving jaw 24 or the second moving jaw 25 moves closer to the other side of the part, the other side of the part abuts against the clamping plate 243, causing the clamping plate 243 to move inward toward the jaw portion 241, compressing the second spring 245. At the same time, the first rack 2434 and the second rack 2435 drive the first tooth bar 2414 and the second tooth bar 2415 to rotate, causing the first chuck 2418 and the second chuck 2419 to move toward each other to achieve clamping. This provides a more stable fixing effect when clamping the part, avoiding the part from moving under force during processing and affecting the accuracy. After processing is completed, when the first moving jaw 24 or the second moving jaw 25 is adjusted away from the other side of the part, under the action of the second spring 245, the clamping plate 243 moves outward relative to the jaw portion 241. The first rack 2434 and the second rack 2435 respectively drive the first toothed bar 2414 and the second toothed bar 2415 to rotate, and respectively drive the first chuck 2418 and the second chuck 2419 to move in opposite directions, so as to open and release the other side of the part. Through the above design, the part can be quickly positioned, stably clamped, and easily flipped, improving processing efficiency and accuracy, and reducing dependence on highly skilled workers and production costs.
[0044] In this embodiment, please refer to Figure 1 Two fixed seats 21 are provided, each fixed to the center of the top surface of the assembly plate 1. Each fixed seat 21 has a rotatable rotating seat 22, and the rotation center lines of the two rotating seats 22 are on the same straight line. The two rotating seats 22 are fixedly connected by a connecting rod 228, which is located on the rotation center line of the two rotating seats 22 and is rotatably connected to the fixed seats 21. Each fixed seat 21 has a first movable gripper 24 and a second movable gripper 25 spaced apart on both sides, with an adjustable distance relative to the fixed seat 21. Specifically, on the top surface of the assembly plate 1, each fixed seat 21 has a third sliding groove 11 and a fourth sliding groove 12 spaced apart on both sides, and the first movable gripper 24 and the second movable gripper 25 are slidably disposed on the third sliding groove 11 and the fourth sliding groove 12, respectively. With this configuration, the clamping plates 23 on the two rotating seats 22 jointly clamp different positions on one side of the part, and the two first moving jaws 24 or the two second moving jaws 25 jointly clamp different positions on the other side of the part, thereby improving the stability of clamping the part.
[0045] In this embodiment, an angle fine-tuning mechanism (not shown) can also be added at the connection between the rotary seat 22 and the connecting rod 228. For example, a high-precision angle adjustment knob and dial can be installed, with the knob connected to the rotary seat 22 via a precision gear transmission. This allows the operator to finely adjust the angle of the part using the angle adjustment knob after it has been flipped, to meet the requirements of processes with extremely high machining angle accuracy. This not only further improves machining accuracy but also adapts to more complex machining needs.
[0046] In this embodiment, please refer to Figure 7 A first connecting rod 246 is fixedly connected between the two first movable grippers 24, and a second connecting rod 247 is fixedly connected between the two second movable grippers 25. Specifically, the two third slide grooves 11 and the two fourth slide grooves 12 respectively penetrate the top and bottom surfaces of the assembly plate 1; the first connecting rod 246 and the second connecting rod 247 are respectively disposed at the bottom of the assembly plate 1, wherein the two ends of the first connecting rod 246 are slidably disposed in the two third slide grooves 11 and are fixedly connected to the movable connecting parts 242 of the two first movable grippers 24; the two ends of the second connecting rod 247 are slidably disposed in the two fourth slide grooves 12 and are fixedly connected to the movable connecting parts 242 of the two second movable grippers 25. A first guide screw 248 and a second guide screw 249 are also rotatably fixedly disposed on both sides of the bottom surface of the assembly plate 1. The bottom surface of the assembly plate 1 is provided with multiple connecting blocks 13. The two ends of the first guide screw 248 and the two ends of the second guide screw 249 are rotatably mounted on the connecting blocks 13, and the directions of the two ends of the first guide screw 248 and the second guide screw 249 are the same as the directions of the two ends of the third slide groove 11 and the fourth slide groove 12, respectively. The first guide screw 248 passes through the first connecting rod 246 and is threadedly connected to the first connecting rod 246; the second guide screw 249 passes through the second connecting rod 247 and is threadedly connected to the second connecting rod 247. With this configuration, rotating the first guide screw can drive the first connecting rod 246 to slide in the third slide groove 11, thereby driving the two first moving jaws 24 to slide in the two third slide grooves 11 respectively, thus moving them away from or closer to the fixed seat 21. Similarly, rotating the second guide screw can drive the second connecting rod 247 to slide in the fourth slide groove 12, thereby driving the two second moving jaws 25 to slide in the two fourth slide grooves 12 respectively, thus moving them away from or closer to the fixed seat 21. The first guide screw 248 and the second guide screw 249 provided in this embodiment can move the two first moving jaws 24 and the two second moving jaws 25 on the top surface of the assembly plate 1, so as to facilitate adjustment according to the size of the parts and be suitable for clamping the parts of various specifications.
