Description

Technical Field

[0001] This utility model belongs to the technical field of prototype model processing equipment, and in particular relates to a positioning mechanism for prototype model processing. Background Technology

[0002] With the continuous shortening of product development cycles and the increasing demand for personalization, prototype models play a crucial role in product design verification, functional testing, and market promotion. The processing accuracy and efficiency of prototype models directly determine the speed and quality of product development. During the processing of prototype models, the positioning mechanism is the core component that ensures that the workpiece is stably and accurately clamped, and its performance directly affects the dimensional accuracy, geometric tolerances, and surface quality of the final model.

[0003] However, existing positioning mechanisms are not easy to lock in place during use. During prototype model machining, the positioning mechanism may loosen unexpectedly due to machining forces and vibrations, affecting the stability of the machining process and making it difficult to provide a reliable fixed foundation for machining operations. Utility Model Content

[0004] The purpose of this utility model is to provide a positioning mechanism for prototype model processing. By setting a locking part, it solves the problem that existing positioning mechanisms are not easy to lock during use, and the positioning mechanism may loosen unexpectedly due to processing force and vibration during processing, affecting the stability of the processing process and making it difficult to provide a reliable fixed foundation for processing operations.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a positioning mechanism for processing prototype models, comprising a base plate, and further comprising: a support portion mounted on the top of the base plate; a locking portion disposed on the base plate; and a positioning portion disposed above the base plate. The locking portion includes a latching assembly mounted on the base plate; and an elastic component disposed on the base plate. The latching assembly includes a fixing block disposed above the base plate, the fixing block having a cylindrical groove inside, and the top of the base plate having several slots. A latching rod passes through the fixing block, and a transmission component is disposed on the latching rod. The outer wall of the latching rod contacts the fixing block. The transmission component includes a knob fixedly connected to the top of the latching rod, and a sliding groove is disposed on the fixing ring. The sliding groove is slidably connected to the fixing block. The latching assembly, through the cooperation of the fixing block, the latching rod, and the slots on the base plate, can fix the relevant components after positioning, preventing them from moving arbitrarily. Under the action of the transmission component, the latching rod can engage or disengage with the slots, providing direct structural support for locking and unlocking operations, ensuring that the positioning mechanism can stably maintain its positioning state during processing.

[0007] Furthermore, the support includes a rotating ring rotatably connected to the top of the base plate, a fixing ring fixedly connected to the top of the base plate, a placement platform fixedly connected to the top of the base plate, the outer wall of the placement platform being fixedly connected to a fixing block, and the bottom of the locking rod extending into a corresponding slot; wherein, the outer wall of the placement platform contacts the inner wall of the rotating ring, and the outer wall of the rotating ring contacts the inner wall of the fixing ring.

[0008] Furthermore, the positioning part includes a transmission assembly disposed on the rotating ring and the fixed ring; and a positioning assembly comprising a plurality of such positioning parts arranged in a circumferential array above the base plate.

[0009] Furthermore, the elastic component includes a slider slidably connected to the inner wall of the cylindrical groove, the locking rod rotating through the slider, two lifting blocks fixedly connected to the inner wall of the cylindrical groove, a spring fixedly connected to the top of the slider, the top of the spring fixedly connected to the top inner wall of the cylindrical groove, and a lifting rod fixedly connected to the outer wall of the locking rod. The lifting rod is located inside the cylindrical groove and contacts the bottom inner wall of the groove, while the bottoms of the two lifting blocks contact the bottom inner wall of the groove. Through the coordinated action of the slider, lifting blocks, spring, and lifting rod, the elastic component provides power and guidance for the locking rod's reset. When unlocking is required, the lifting rod is lifted by the lifting blocks, causing the locking rod to disengage from the slot, and the spring is compressed. After unlocking, the spring force automatically resets the slider and locking rod, allowing the locking rod to re-engage in the slot and achieve locking. This simplifies the operation process, ensures the reliability and timeliness of the locking action, and enhances the ease of use of the positioning mechanism.

[0010] Furthermore, the transmission assembly includes a handle fixedly connected to the outer wall of the rotating ring, and an arc groove is provided on the fixed ring; wherein, the handle extends to the outside of the fixed ring through the arc groove. The transmission assembly is a power transmission structure for the positioning part to realize positioning adjustment. The handle extending to the outside of the fixed ring through the arc groove facilitates the operator to control the rotation of the rotating ring. The rotation of the rotating ring will drive the positioning assembly to perform linkage, thereby realizing the positioning action of the positioning wheel on the hand model. This provides a convenient external force input method for positioning operation, enabling the operator to easily drive the positioning part to complete the positioning adjustment of the hand model, and improving the flexibility of operation.

[0011] Furthermore, the positioning component includes a hollow rectangular block hinged to the top of the fixed ring. A rectangular slider is slidably connected to the inner wall of the hollow rectangular block. A hinge rod is fixedly connected to the side of the rectangular slider away from the rectangular block. Two positioning wheels are rotatably connected to the hinge rod. The hinge rod is hinged to the rotating ring. The positioning component is the direct execution structure for the positioning part to position the prototype model. Multiple positioning components arranged in a circular array can approach the prototype model from different directions through the cooperation of the hollow rectangular block, the rectangular slider, the hinge rod, and the positioning wheels. Driven by the rotating ring, the positioning wheels can achieve centered positioning and fixation of the model. The sliding of the rectangular slider within the hollow rectangular block adapts to the positioning requirements of models of different sizes.

[0012] This utility model has the following beneficial effects:

[0013] 1. By setting a locking part, the cooperation between the buckle assembly and the elastic assembly can fix the rotatable parts in the positioning mechanism. The buckle rod in the buckle assembly can engage or disengage with the slot on the base plate under the action of the transmission component. The elastic assembly uses springs and other structures to assist the buckle rod in resetting, thereby locking the rotating ring after positioning is completed, preventing the positioning mechanism from accidentally loosening during the processing of the prototype model, ensuring the stability of the processing process, and providing a reliable fixed foundation for processing operations.

[0014] 2. By setting up a positioning part, the prototype model is centered and fixed. The transmission component can drive the rotating ring to rotate, and then through the linkage of the hollow rectangular block, hinge rod and other components in the positioning component, the positioning wheel moves closer to the prototype model. Multiple positioning wheels are used to center the model from different directions, ensuring that the model is in the preset accurate position during processing, improving the positioning accuracy and efficiency, and meeting the position accuracy requirements of prototype model processing.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

The outer wall of the placement platform 114 contacts the inner wall of the rotating ring 112, and the outer wall of the rotating ring 112 contacts the inner wall of the fixing ring 113.

[0026] The locking part 2 includes a latching assembly 21 mounted on the base plate 111; and an elastic assembly 22 disposed on the base plate 111. The latching assembly 21 includes a fixing block 211 disposed above the base plate 111, a cylindrical groove 212 formed in the fixing block 211, and several slots 213 formed on the top of the base plate 111. A latching rod 214 passes through the fixing block 211, and a transmission component is disposed on the latching rod 214. The outer wall of the latching rod 214 contacts the fixing block 211. The elastic assembly 22 includes a slider 221 slidably connected to the inner wall of the cylindrical groove 212. The latching rod 214 rotates through the slider 221. Two lifting blocks 222 are fixedly connected to the inner wall of the cylindrical groove 212. The top of the slider 221 is fixed. A spring 223 is connected, with its top fixedly connected to the inner top wall of the cylindrical groove 212. A lifting rod 224 is fixedly connected to the outer wall of the locking rod 214. The lifting rod 224 is located inside the cylindrical groove 212 and contacts the inner bottom wall of the cylindrical groove 212. The bottoms of the two lifting blocks 222 are in contact with the inner bottom wall of the cylindrical groove 212. The transmission component includes a knob 215 fixedly connected to the top of the locking rod 214. A sliding groove 216 is provided on the fixing ring 113. The sliding groove 216 is slidably connected to the fixing block 211. By setting the locking part 2, the rotating ring is locked after positioning to prevent the placement table from rotating accidentally during the processing of the prototype model, ensuring the stability and accuracy of the processing process and providing a reliable fixed foundation for the processing operation.

[0027] The positioning part 3 includes a transmission assembly 31, which is disposed on the rotating ring 112 and the fixed ring 113; and a positioning assembly 32, which comprises several positioning parts 3 arranged in a circumferential array above the base plate 111. The transmission assembly 31 includes a handle 311 fixedly connected to the outer wall of the rotating ring 112, and the fixed ring 113 has an arc groove 312. The handle 311 extends to the outside of the fixed ring 113 through the arc groove 312. The positioning assembly 32 includes a hinged part disposed on the fixed ring 113. The hollow rectangular block 321 at the top of the ring 113 has a rectangular slider 322 slidably connected to its inner wall. A hinge rod 323 is fixedly connected to the side of the rectangular slider 322 away from the hollow rectangular block 321. Two positioning wheels 324 are rotatably connected to the hinge rod 323. The hinge rod 323 is hinged to the rotating ring 112. By setting the positioning part 3, the model is ensured to be in the preset position during processing, which improves the stability and efficiency of positioning and meets the requirements of the prototype model processing for the center position.

[0028] A specific application of this embodiment is as follows: In use, the prototype model is placed on the placement platform 114. The knob 215 is rotated, causing the lifting rod 224 to rotate via the locking rod 214. As the lifting rod 224 rotates, it is lifted by the two lifting blocks 222, causing the locking rod 214 to move upwards. The slider 221 moves upwards with the locking rod 214 and compresses the spring 223, until the lifting rod 224 reaches the horizontal portion of the two lifting blocks 222. At this point, the bottom of the locking rod 214 also leaves the corresponding slot 213. The knob 215 is then stopped, and the positioning part 3 can be controlled by the handle 311 to center and fix the prototype model. After positioning, the locking rod 214 is rotated again, causing the lifting rod 224 to leave the two lifting blocks 222. The spring 223 then drives the slider 221 and... The locking lever 214 is reset, locking itself in the corresponding slot 213, thereby locking the rotating ring 112 to prevent it from rotating accidentally during processing. After the locking lever 214 leaves the slot 213, the handle 311 is pushed, and the handle 311 drives the rotating ring 112 to rotate. The rotating ring 112 drives the hinge rod 323 to rotate around the hinge axis between the hinge rod 323 and the fixed ring 113 through the hollow rectangular block 321. This causes the two positioning wheels 324 on the hinge rod 323 to approach the prototype model, while the rectangular slider 322 retracts into the hollow rectangular block 321. Thus, the positioning wheels 324 of the three positioning components 32 are all close to the center of the rotating ring 112, centering and fixing the prototype model. Then, the rotating ring 112 is locked by the locking part 2 to complete the centering and fixing of the prototype model.
