Description

Technical Field

[0001] This utility model relates to the field of tooling and fixture technology, specifically a dimensional control tooling for processing rigid carbon fiber circular products in an induction furnace. Background Technology

[0002] Rigid carbon fiber circular products are circular structural components manufactured using pre-impregnated resin curing technology based on high-performance carbon fiber composite materials. They possess characteristics such as lightweight, high strength, corrosion resistance, and excellent thermal stability, and are widely used in aerospace, automotive, and sporting goods industries. During the processing of these products, the dimensions are strictly controlled to ensure that the finished product meets shape requirements.

[0003] Utility model patent CN213004927U discloses a dimension control device for processing circular products. This utility model utilizes the mutual cooperation of a first housing, a second housing, a fixing ring, a first fixing seat, a second fixing seat, a first bevel gear, a rotating rod, a second bevel gear, a circular bevel gear ring, a threaded rod, and a nut sleeve. Through the cooperation of the first and second housings, the workpiece body can be quickly measured and marked. Furthermore, by rotating the rotating rod, the circular bevel gear ring can be rotated, simultaneously moving three arc-shaped plates to fix and clamp the workpiece body. Therefore, this device can quickly measure and mark the workpiece body while simultaneously fixing it by simply rotating the rotating rod. Operation is convenient and simple, increasing work efficiency and ensuring stability during cutting.

[0004] While the aforementioned device can simultaneously measure, mark, and control the workpiece, and is convenient and simple to operate, increasing work efficiency and ensuring stability during cutting, it requires placing the measuring device at the center of the circular workpiece before dimensional measurement can be performed. However, in actual operation, if it is necessary to measure the dimensions of the circular workpiece or cut a hole in its center, finding the center of the circular workpiece is difficult, as the device lacks a means to efficiently locate the center. Furthermore, after fixing the circular workpiece, the device cannot rotate the workpiece to adjust the processing angle, which may cause inconvenience to the processing work. Therefore, to address the above problems, a dimensional control fixture for processing rigid carbon fiber circular products in an induction furnace is proposed. Utility Model Content

[0005] To address the technical problems in comparative technologies where tooling fixtures lack efficient means of locating the center of a circle, making it difficult to accurately locate the center during measurement and hole machining, and preventing the workpiece from being rotated and adjusted after being fixed, thus causing inconvenience to the machining process, this utility model provides a dimensional control tooling for machining hard carbon fiber circular products in an induction furnace.

[0006] The technical solution adopted by the embodiments of this application to solve its technical problem is: A dimensional control fixture for processing rigid carbon fiber circular products in an induction furnace includes a U-shaped frame with a rotatably connected tilting plate mounted on its top. Tilting locking mechanisms are installed on both sides of the tilting plate to lock its rotation angle. The tilting plate has cross-shaped adjustable grooves, in which clamping blocks are slidably mounted. A screw drive mechanism is installed on the back of the tilting plate to drive opposing clamping blocks to move synchronously closer or further away. A center positioning element is mounted on the clamping blocks in a crisscross arrangement. The center positioning element includes a positioning strip, one end of which is fixedly mounted on the clamping block via a mounting sleeve, and the other end has a positioning groove that is slidably connected to the opposing clamping block. The two crisscrossing positioning grooves enclose a rectangular positioning hole.

[0007] In one possible implementation, the center positioning element is equipped with a cooperating center marking bar, which includes a rectangular bar that matches the size of the rectangular positioning hole, and an annular head is fixedly provided at the end of the rectangular bar.

[0008] In one possible implementation, the clamping block includes a sliding block with a contact element installed at its front end and a mounting shaft fixedly installed at its top end, wherein the mounting sleeve is sleeved on the mounting shaft and the mounting shaft slides in contact with the wall of the positioning groove.

[0009] In one possible implementation, the contact element includes a support platform, the upper surface of which is fixedly provided with an alignment plate that fits against the sliding block, and an anti-detachment piece is fixedly connected to the top of the alignment plate.

[0010] In one possible implementation, the screw drive mechanism includes several end constraint plates fixedly mounted on the back of the flip disk, on which two bidirectional screws perpendicular to each other are rotatably mounted. Each bidirectional screw is threaded with two symmetrically arranged slides, which are fixedly connected to the corresponding clamping blocks, and each end of the bidirectional screw is connected with an adjusting wheel.

[0011] In one possible implementation, the middle section of the bidirectional screw is a smooth section, and the threads on both sides are opposite. A cross-shaped constraint seat is fixedly provided in the middle of the back of the flip disk, and the smooth section of the bidirectional screw is located in the cross-shaped constraint seat and rotatably connected to it.

[0012] In one possible implementation, the rotating disk is fixedly provided with symmetrically arranged rotating shafts, and the top of the U-shaped frame is fixedly provided with a bearing seat, wherein the rotating shaft is inserted into the bearing seat and fixedly connected to its rotating inner ring.

[0013] In one possible implementation, the tilt locking mechanism includes a mating sleeve fixedly disposed on the outer end face of the bearing housing, and the end of the rotating shaft is threaded with a locking wheel threadedly connected thereon.

[0014] In summary, this utility model has the following beneficial technical effects: Since the clamping blocks are arranged in a cross shape, two opposite clamping blocks can form a set of clamps to clamp and position the circular workpiece. Furthermore, since the opposite clamping blocks can move closer or further away synchronously under the action of the screw drive mechanism, the positioning accuracy can be ensured. With the above scheme, after all the clamping blocks are attached to and clamped to the side of the circular workpiece, it can be ensured that the circular workpiece is fixed in the center of the flipping disk. Since a set of clamping blocks is equipped with a center positioning component, and the positioning groove on it coincides with the center of the circular workpiece, the center position of the circular workpiece can be determined by the intersection of the two intersecting positioning grooves. That is, the positioning grooves form a rectangular positioning hole corresponding to the center position. At this time, by inserting the center marking rod into the rectangular positioning hole, the ring head can imprint a positioning mark on the surface of the circular workpiece, which facilitates the smooth operation of center machining. Furthermore, since the rotating disc is rotatably connected to the U-shaped frame by inserting a rotating shaft into the bearing seat, the orientation of the round workpiece can be adjusted by rotating the rotating disc during processing to meet different processing requirements. After the rotation angle is adjusted, the tilt angle of the rotating disc can be fixed by tightening the locking wheel to prevent it from rotating during processing and affecting the smooth progress of processing.

[0017] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows: like Figure 1 - Figure 2 As shown in the figure, the dimensional control fixture for processing rigid carbon fiber circular products in an induction furnace provided in this embodiment includes a U-shaped frame 1, on the top of which is a rotating disk 2 rotatably connected, and tilt locking mechanisms 3 are installed on both sides of the rotating disk 2 to lock the rotation angle of the rotating disk 2; the rotating disk 2 has adjustable grooves 22 arranged in a cross shape, in which clamping blocks 4 are slidably installed, and a screw drive mechanism 5 is installed on the back of the rotating disk 2 to drive the opposite clamping blocks 4 to move closer or further away synchronously; a center positioning member 6 is installed on the clamping blocks 4 and is arranged in a cross shape.

[0018] Based on the above technical solution, since the clamping blocks 4 are arranged in a cross shape, two opposing clamping blocks 4 can form a set of fixtures to clamp and position the circular workpiece. Furthermore, since the opposing clamping blocks 4 can move closer or further away synchronously under the action of the screw drive mechanism 5, the positioning accuracy can be ensured. Through this solution, after all the clamping blocks 4 are in contact with and clamped to the side of the circular workpiece, the circular workpiece can be fixed at the center of the rotating disk 2. Simultaneously, the center positioning component 6 can locate the center position of the circular workpiece. In addition, since the rotating disk 2 is rotatably connected to the U-shaped frame 1, the orientation of the circular workpiece can be adjusted by rotating the rotating disk 2 during processing to meet different processing requirements. After the angle adjustment is completed, the tilt angle of the rotating disk 2 can be fixed by tightening the locking wheel 32 to prevent it from rotating during processing and affecting the smooth progress of processing.

[0019] Among them, such as Figure 2As shown, the center positioning component 6 includes a positioning strip 61, one end of which is fixedly mounted on the clamping block 4 via a mounting sleeve 62, and the other end has a positioning groove 63, which is slidably connected to the opposite clamping block 4. Two intersecting positioning grooves 63 enclose a rectangular positioning hole. Furthermore, the center positioning component 6 is equipped with a cooperating center marker rod 7, such as... Figure 5 As shown, it includes a rectangular bar 71 that matches the size of the rectangular positioning hole. An annular head 72 is fixedly provided at the end of the rectangular bar 71. Based on the above structure, since the center line of the positioning groove 63 coincides with the center of the circular workpiece, the center position of the circular workpiece can be determined by the intersection of the two intersecting positioning grooves 63. That is, the positioning grooves 63 enclose a rectangular positioning hole corresponding to the center position. At this time, by inserting the center marking bar 7 into the rectangular positioning hole, the annular head 72 can imprint a positioning mark on the surface of the circular workpiece, which facilitates the smooth operation of the center machining.

[0020] like Figure 4 As shown, the clamping block 4 includes a sliding block 41 with a contact element 42 installed at its front end and a mounting shaft 43 fixedly installed at its top end. The mounting sleeve 62 is sleeved on the mounting shaft 43, and the mounting shaft 43 slides in contact with the groove wall of the positioning slide groove 63. In the above structure, the sliding block 41 adjusts its position by moving the contact element 42 on it through sliding. The contact element 42 directly contacts the circular workpiece to clamp and fix it. In addition, the mounting shaft 43 provides the necessary structural foundation for the installation and operation of the center positioning element 6.

[0021] The contact element 42 includes a support platform 421, on the upper surface of which an alignment plate 422 is fixedly disposed and fits against the sliding block 41. An anti-detachment piece 423 is fixedly connected to the top of the alignment plate 422. In the above structure, the support platform 421 can suspend the circular workpiece in the air, which is convenient for processing and avoids the processing equipment from colliding with the flipping disk 2 during processing. The alignment plate 422 can achieve tangential contact with the edge of the circular workpiece to prevent the circular workpiece from sliding and shifting during the clamping process. In addition, the anti-detachment piece 423 can prevent the circular workpiece from sliding out during the clamping process.

[0022] To ensure that the opposing clamping blocks 4 can move closer or further away synchronously under the action of the screw drive mechanism 5, such as Figure 3As shown, the screw drive mechanism 5 includes several end constraint plates 51 fixedly mounted on the back of the rotating disk 2. Two bidirectional screws 52 perpendicular to each other are rotatably mounted on the end constraint plates 51. Each bidirectional screw 52 is threaded with two symmetrically arranged slides 53, which are fixedly connected to the corresponding clamping blocks 4. Each end of each bidirectional screw 52 is connected to an adjusting wheel 54. When the bidirectional screw 52 is rotated by turning the adjusting wheel 54, the two opposing slides 53 connected to it can move closer or further away synchronously, thereby driving the corresponding clamping blocks 4 to move closer or further away synchronously, so as to complete the positioning and clamping of the circular workpiece.

[0023] The bidirectional screw 52 has a smooth section in the middle, and the threads on both sides are opposite. A cross constraint seat 55 is fixedly installed in the middle of the back of the flip disk 2. The smooth section of the bidirectional screw 52 is located in the cross constraint seat 55 and is rotatably connected to it. The above structure can constrain and support the middle of the bidirectional screw 52 with the cross constraint seat 55, preventing the bidirectional screw 52 from bending during use due to its excessive length.

[0024] like Figure 1 As shown, a symmetrically arranged rotating shaft 21 is fixedly installed on the rotating disk 2, and a bearing seat 11 is fixedly installed at the top of the U-shaped frame 1. The rotating shaft 21 is inserted into the bearing seat 11 and fixedly connected to its rotating inner ring. Through the above structure, the rotating disk 2 and the U-shaped frame 1 can be rotated together, providing the necessary structural basis for adjusting the rotation angle of the rotating disk 2. Correspondingly, the tilt angle locking mechanism 3 includes a mating cylinder 31 fixedly installed on the outer end face of the bearing seat 11. The end of the rotating shaft 21 is threaded, and a locking wheel 32 is threadedly connected to it. After the rotation angle is adjusted, the tilt angle of the rotating disk 2 can be fixed by tightening the locking wheel 32 to make it squeeze and rub against the mating cylinder 31, so as to prevent it from rotating during the processing and affecting the smooth progress of the processing.

[0025] The working principle and usage process of this utility model: During installation, the circular workpiece is placed on the flip plate 2. When the bidirectional screw 52 is turned by adjusting the wheel 54, the two opposing slides 53 connected to it can move closer or further away synchronously, thereby driving the corresponding clamping blocks 4 to move closer or further away synchronously. After all the clamping blocks 4 are in contact with the side of the circular workpiece and clamped, it can be ensured that the circular workpiece is fixed at the center of the flip plate 2.

[0026] During the clamping process described above, the intersecting center positioning members 6 will move synchronously. Since the center line of the positioning groove 63 coincides with the center of the circular workpiece, the center position of the circular workpiece can be determined by the intersection of the two intersecting positioning grooves 63. That is, the positioning grooves 63 enclose a rectangular positioning hole corresponding to the center position. At this time, by inserting the center marking rod 7 into the rectangular positioning hole, the annular head 72 can imprint a positioning mark on the surface of the circular workpiece, which facilitates the smooth operation of the center machining.

[0027] Furthermore, during the processing, if the orientation of the circular workpiece needs to be adjusted, the locking wheel 32 can be loosened to separate it from the mating cylinder 31. At this time, the tilting disc 2 can automatically rotate to adjust the tilt angle. After the adjustment is completed, the tilt angle of the tilting disc 2 can be fixed by tightening the locking wheel 32 to make it squeeze and rub against the mating cylinder 31, so as to prevent it from rotating during the processing and affecting the smooth progress of the processing.

[0028] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
