Description

Technical Field

[0001] This utility model belongs to the field of stretching parts processing technology, and specifically relates to a vertical lathe processing mechanism for positioning and stretching parts. Background Technology

[0002] In the field of vertical machining of bent and stretched parts, these workpieces are formed by bending and stretching processes, and their surfaces are mostly irregular arc-shaped and often have teeth, which are significantly different from the regular structure of ordinary machined parts.

[0003] Existing positioning mechanisms mostly use ordinary three-jaw chucks or simple pressure plate structures, which are difficult to adapt to the irregular arc structure of bent and stretched parts, resulting in insufficient positioning accuracy. The clamping surface of ordinary three-jaw mechanisms is a standardized design, which cannot fit with the arc surface of bent and stretched parts, and is prone to clamping offset. In addition, the connection between the clamping component and the positioning component of some positioning mechanisms is complicated. During assembly, multiple connecting parts need to be aligned with special tools, which is cumbersome and time-consuming. When it is necessary to change bent and stretched parts of different specifications, the disassembly and assembly efficiency is low, which affects the continuity of processing. Utility Model Content

[0004] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a vertical machining mechanism for positioning bending and stretching parts, so as to solve the problems in the background art.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A vertical machining mechanism for positioning and stretching parts includes a positioning chuck and a tensioning plate. First docking blocks are fixedly connected to both sides of one end of the positioning chuck, and second docking blocks are fixedly connected to both sides of one end of the tensioning plate. A ring seat is fixedly connected to the end of the tensioning plate near the positioning chuck, and multiple toothed blocks are fixedly connected to the periphery of the ring seat. A connecting component is provided between the first and second docking blocks, and an elastic component is provided on one side of the connecting component.

[0007] As a preferred technical solution, the connecting component includes a plug, which is fixedly connected to both sides of one end of the tensioning plate and fixedly connected to one side of the second docking block. A slot is provided on one side of the first docking block, and the plug is inserted into the inside of the slot. A locking hole is provided inside the plug, and a locking block is movably connected inside the slot. There are two locking blocks, and both locking blocks are movably connected to the locking hole through an elastic component.

[0008] As a preferred technical solution, the elastic component includes an assembly groove, which is formed inside the first mating block. A slider is slidably connected inside the assembly groove. One side of the slider is fixedly connected to one side of the locking block. A spring is fixedly connected between the slider and the assembly groove. Guide grooves are formed on both sides inside the assembly groove. A guide block is slidably connected inside the guide groove. One side of the guide block is fixedly connected to one side of the slider.

[0009] As a preferred technical solution, connecting rods are fixedly connected to both sides of the insertion block on the tensioning plate, and connecting grooves are opened on both sides of the slot on the first mating block. The connecting rods are movably connected to the connecting grooves, and a mating hole is opened inside the connecting rod. A mating rod is inserted into the mating hole, and the mating rod is fixedly connected inside the connecting groove.

[0010] In summary, the present invention has the following main advantages:

[0011] First, this utility model, by installing multiple toothed blocks on the periphery of the tensioning plate, can precisely mesh with the teeth of the bending and stretching parts to form a special toothed positioning structure, ensuring the positional accuracy of the workpiece teeth and the processing datum, avoiding tooth size deviation after processing, and meeting the positioning requirements of the irregular arc structure of the bending and stretching parts.

[0012] Secondly, this utility model, by setting up connecting components and elastic components, only requires inserting the insert block into the slot during assembly. The locking block automatically engages with the locking hole under the action of the spring, completing the locking without the need for special tools. During disassembly, simply pressing the locking block releases the lock, making the operation convenient. At the same time, the cooperation between the connecting rod and the connecting groove, and between the insert rod and the insert hole, can further improve the connection stability between the positioning chuck and the tensioning plate, avoiding loosening of the connection during processing. This design significantly shortens the changeover time for bending and stretching parts of different specifications, improves processing continuity, reduces the labor intensity of operators, and adapts to the needs of batch processing scenarios.

[0018] Example

[0019] refer to Figures 1 to 4 This embodiment describes a vertical machining mechanism for positioning bent and stretched parts, comprising a positioning chuck 1 and a tensioning plate 2. First docking blocks 5 are fixedly connected to both sides of one end of the positioning chuck 1, and second docking blocks 6 are fixedly connected to both sides of one end of the tensioning plate 2. A ring seat 3 is fixedly connected to the end of the tensioning plate 2 closest to the positioning chuck 1. Multiple toothed blocks 4 are fixedly connected to the periphery of the ring seat 3. A connecting component 7 is provided between the first docking blocks 5 and the second docking blocks 6, and an elastic component 8 is provided on one side of the connecting component 7. The multiple toothed blocks 4 on the ring seat 3 can precisely mesh with the teeth of the bent and stretched parts, forming a dedicated toothed positioning structure. This prevents circumferential displacement of the workpiece during machining due to lack of tooth positioning, ensuring the positional accuracy of the teeth relative to the machining reference. The cooperation between the positioning chuck 1 and the tensioning plate 2 provides stable clamping force from both sides of the workpiece, adapting to the irregular arc-shaped structural characteristics of the bent and stretched parts and solving the problem that ordinary three-jaw mechanisms cannot achieve close clamping.

[0020] refer to Figure 2-3The connecting component 7 includes insert blocks 71, which are fixedly connected to both sides of one end of the tensioning plate 2 and to one side of the second docking block 6. A slot 73 is provided on one side of the first docking block 5, and the insert blocks 71 are inserted into the slot 73. A locking hole 72 is provided inside the insert blocks 71. Two locking blocks 74 are movably connected inside the slot 73, and both locking blocks 74 are movably connected to the locking hole 72 via an elastic component 8. When assembling the positioning clamp 1 and the tensioning plate 2, the insert blocks 71 on both sides of one end of the tensioning plate 2 are aligned with the slots 73 on the first docking block 5. Pushing the tensioning plate 2 causes the insert 71 to be inserted into the slot 73. During insertion, the insert 71 presses against the two locking blocks 74 in the slot 73. When the locking hole 72 on the insert 71 is aligned with the locking block 74, the locking block 74 springs into the locking hole 72 under the action of the elastic component 8, thus locking the positioning clamp 1 and the tensioning plate 2. When disassembling, press the locking block 74 to disengage it from the locking hole 72, and then pull the tensioning plate 2 in the opposite direction to pull the insert 71 out of the slot 73, thus separating the two. The operator can manually complete the locking and unlocking, simplifying the disassembly and assembly process. Especially when changing bending and stretching parts of different specifications, it can greatly shorten the replacement time.

[0021] refer to Figure 4 The elastic component 8 includes an assembly groove 81, which is formed inside the first mating block 5. A slider 82 is slidably connected inside the assembly groove 81, and one side of the slider 82 is fixedly connected to one side of the locking block 74. A spring 83 is fixedly connected between the slider 82 and the assembly groove 81. Guide grooves 84 are formed on both sides inside the assembly groove 81, and guide blocks 85 are slidably connected inside the guide grooves 84. One side of the guide block 85 is fixedly connected to one side of the slider 82. By setting the elastic component 8, when the insertion block 71 is inserted into the slot 73, it compresses the locking block 74. When the locking block 74 moves the slider 82 within the assembly groove 81, the slider 82 compresses the spring 83 within the assembly groove 81. Simultaneously, the guide blocks 85 on both sides of the slider 82 slide synchronously along the guide groove 84. When the locking hole 72 aligns with the locking block 74, the spring 83 releases its elastic force to push the slider 82 back to its original position. The slider 82 then moves the locking block 74 into the locking hole 72 to complete the locking. When the locking block 74 is disassembled and pressed, it again moves the slider 82 to compress the spring 83. The guide blocks 85 slide along the guide groove 84 to limit the slider 82 from shifting. After the locking block 74 is released, the spring 83 can again move the slider 82 and the locking block 74 back to their original positions.

[0022] refer to Figure 2 and Figure 4The tensioning plate 2 has connecting rods 9 fixedly connected to both sides of the insertion block 71. The first mating block 5 has connecting grooves 11 on both sides of the slot 73. The connecting rods 9 are movably connected to the connecting grooves 11. The connecting rods 9 have mating holes 10 inside, and mating rods 12 are inserted into the mating holes 10. The mating rods 12 are fixedly connected inside the connecting grooves 11. When assembling the positioning chuck 1 and the tensioning plate 2, at the same time as the insertion block 71 is inserted into the slot 73, the connecting rods 9 on both sides of the insertion block 71 on the tensioning plate 2 are simultaneously aligned with the first mating rods 9. As the insert block 71 is inserted, the connecting rod 9 is inserted into the connecting groove 11 on the connecting block 5, and the mating rod 12 in the connecting groove 11 is inserted into the mating hole 10 on the connecting rod 9. When disassembling, as the insert block 71 is pulled out from the slot 73, the connecting rod 9 is simultaneously pulled out from the connecting groove 11, and the mating rod 12 is disengaged from the mating hole 10, completing the overall separation. The cooperation between the connecting rod 9 and the connecting groove 11 can further strengthen the connection between the positioning clamp 1 and the tensioning plate 2 from both sides of the insert block 71, avoiding structural displacement caused by unilateral force when the insert block 71 is locked, and improving the overall connection strength.

[0023] Operating principle and advantages: First, the bending and stretching part to be processed is placed between the positioning chuck 1 and the tensioning plate 2, so that the teeth of the workpiece precisely mesh with the multiple tooth blocks 4 on the periphery of the ring seat 3 at one end of the tensioning plate 2, completing the pre-positioning of the teeth. Then, the tensioning plate 2 is pushed so that the insert blocks 71 on both sides of one end of the tensioning plate 2 are aligned with the slots 73 on the first mating block 5 of the positioning chuck 1 and inserted. During the insertion process, the insert blocks 71 squeeze the two locking blocks 74 in the slots 73, causing the locking blocks 74 to compress the springs 83 in the assembly groove 81 through the slider 82. At the same time, the guide blocks 85 on both sides of the slider 82 slide along the guide groove 84. When the locking holes 72 on the insert blocks 71 are aligned with the locking blocks 74, the springs 83 release their elasticity, push the slider 82 to reset, and cause the locking blocks 74 to spring into the locking holes. 72. Locking of the positioning chuck 1 and the tensioning plate 2 is completed. During this process, the connecting rods 9 on both sides of the insert block 71 on the tensioning plate 2 will be inserted into the connecting groove 11 of the first mating block 5. The mating rods 12 in the connecting groove 11 will also be inserted into the mating holes 10 of the connecting rods 9 to further strengthen the connection. After clamping, the vertical lathe processing equipment is started to cut the workpiece. When the processing is completed or the workpiece needs to be replaced, press the locking block 74 to disengage it from the locking hole 72, pull the tensioning plate 2 in the opposite direction, so that the insert block 71 is pulled out from the slot 73 and the connecting rod 9 is pulled out from the connecting groove 11. The workpiece can then be removed or a new workpiece can be replaced. This solves the problem of positional deviation caused by the lack of dedicated tooth positioning in the existing technology, ensures that the workpiece teeth are aligned with the processing datum, and avoids tooth size errors after processing.
