Description

Technical Field

[0001] This utility model relates to the field of tooling and fixture technology, and in particular to a fixing tool for processing flower drums. Background Technology

[0002] In the process of hub processing, fixed fixtures are needed to position and fix the hubs to be processed to ensure processing accuracy and efficiency. However, existing hub processing fixed fixtures often have significant shortcomings: on the one hand, most fixtures can only position and fix a single hub, and cannot simultaneously achieve multi-station processing, resulting in low processing efficiency and difficulty in meeting the needs of mass production; on the other hand, they have poor adaptability, and the size and position of the fixing structure are mostly fixed designs, which cannot be flexibly adjusted according to the different diameters of the hubs to be processed. When dealing with hubs with large diameter differences, it is necessary to change to fixtures of the corresponding specifications to complete the fixing. This not only increases the cost of purchasing fixtures and storage space, but also prolongs the processing preparation time due to frequent disassembly and assembly of fixtures, seriously affecting the continuity of production.

[0003] Therefore, those skilled in the art have provided a fixed tooling for hub processing to solve the problems mentioned in the background art. Utility Model Content

A support block is slidably connected in each guide hole. One end of the support block is located inside the positioning sleeve, and the other end extends out of the positioning sleeve.

[0010] The end of the support block located inside the positioning sleeve is fixedly connected to a fitting block. The side of the fitting block near the push block is provided with an inclined surface structure that is adapted to the opposite direction of the inclined surface of the push block, and the two inclined surfaces are tightly fitted together.

[0011] Preferably, the tensioning block is located on one side inside the positioning sleeve rod, and both its upper and lower ends are integrally formed with anti-detachment blocks.

[0012] Preferably, a positioning rod is fixedly connected to the middle of the top end of the inner side of the positioning sleeve rod, and a plurality of guide rods arranged in a ring array are fixedly connected to the outer wall of the positioning rod along its circumference.

[0014] A tension spring is fitted on the outer side of the guide rod. One end of the tension spring is fixed to the outer wall of the positioning rod, and the other end is fixed to the side wall of the fitting block near the positioning rod.

[0015] Preferably, a plurality of bearing rods arranged in a ring array are fixedly connected to the bottom edge of the bearing seat, and the bottom ends of the plurality of bearing rods are fixedly connected to a bearing seat.

[0016] The top of the receiving seat is fixed with multiple limiting tubes arranged in a ring array. The number of limiting tubes corresponds one-to-one with the number of positioning sleeve rods, and the limiting tubes are set in the vertical direction.

[0017] The inner side of the limiting tube is slidably connected to an internally threaded cylinder with its opening facing downwards, and the top end of the internally threaded cylinder is fixedly connected to the bottom end of the movable rod.

[0018] The inner side of the internally threaded cylinder is connected to a threaded column by a thread.

[0024] Compared with the prior art, the beneficial effects of this utility model are:

[0025] This hub machining fixture uses multiple positioning sleeves arranged in a ring on the support base to simultaneously fix multiple hubs. Combined with an automated drive assembly consisting of a drive motor driving a gear set, threaded column, and internal threaded cylinder, it can achieve multi-station synchronous processing, significantly improving processing efficiency and meeting the needs of mass production. At the same time, relying on the structure where the push block pushes the tensioning block to extend and retract radially through the fitting block when the movable rod moves down, the tensioning range can be flexibly adjusted according to the hub diameter. It can adapt to hubs of different diameters without changing the fixture, which reduces the cost of fixture procurement and storage requirements, and avoids the extension of processing preparation time due to frequent disassembly and assembly of fixtures, effectively ensuring production continuity.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0035] Reference Figure 1-6 A fixed fixture for processing a flower drum includes a support base 1. A plurality of positioning sleeve rods 2 arranged in a circular array are fixedly connected to the top of the support base 1. The positioning sleeve rods 2 are hollow structures with closed top and bottom, and the flower drum to be processed is sleeved on the outside of the positioning sleeve rods 2.

[0036] A movable rod 3 is provided on the inner middle of the positioning sleeve rod 2 along its axial direction. The bottom end of the movable rod 3 passes through the bottom end of the positioning sleeve rod 2 and the bearing seat 1 in sequence, and the movable rod 3 can slide up and down along the axial direction of the positioning sleeve rod 2.

[0037] Multiple push blocks 4 arranged in a ring array are fixed to the outer wall of the movable rod 3 along its circumference. The side of the push block 4 closest to the inner wall of the positioning sleeve rod 2 has an inclined structure.

[0038] The outer wall of the positioning sleeve rod 2 is provided with a plurality of guide holes arranged in a ring array along its circumference. The guide holes are opened along the radial direction of the positioning sleeve rod 2, and the number of guide holes corresponds one-to-one with the number of push blocks 4. A support block 5 is slidably connected in each guide hole. One end of the support block 5 is located inside the positioning sleeve rod 2, and the other end extends out of the positioning sleeve rod 2.

[0039] The end of the tensioning block 5 located inside the positioning sleeve rod 2 is fixedly connected to the fitting block 6. The side of the fitting block 6 near the push block 4 is provided with an inclined surface structure that is adapted to the inclined surface of the push block 4 in the opposite direction, and the two inclined surfaces are tightly fitted together.

[0040] Using the above technical solution, after the hub to be processed is sleeved on the outside of the positioning sleeve rod 2, the movable rod 3 slides downward along the axial direction of the positioning sleeve rod 2. The pushing block 4 on the outer wall of the movable rod 3 moves downward accordingly. Since the side of the pushing block 4 near the inner wall of the positioning sleeve rod 2 is a sloping structure, and this sloping surface is closely fitted with the opposite matching sloping surface of the fitting block 6, the downward-moving pushing block 4 will generate radial thrust through the sloping surface transmission, pushing the fitting block 6 and the support block 5 fixed to it to slide outward along the radial guide hole of the positioning sleeve rod 2. Finally, the end of the support block 5 extending outward from the outside of the positioning sleeve rod 2 is tightly abutted against the inner wall of the hub to be processed, realizing the rapid centering and tight fixing of the hub to be processed, effectively avoiding the hub from shifting or shaking during processing, and ensuring processing accuracy. At the same time, multiple positioning sleeve rods 2 and support blocks 5 distributed in a ring array can simultaneously fix multiple hubs, improving processing efficiency.

[0041] The tensioning block 5 is located on one side inside the positioning sleeve rod 2, and both its upper and lower ends are integrally formed with anti-detachment blocks 7.

[0042] By adopting the above technical solution, a reliable anti-detachment limiting structure is formed by the anti-detachment block 7; the maximum extension distance of the support block 5 is limited, and the support block 5 is prevented from detaching from the guide hole due to excessive sliding.

[0043] A positioning rod 8 is fixedly connected to the middle of the top end of the inner side of the positioning sleeve rod 2. Multiple guide rods 9 arranged in a ring array are fixedly connected to the outer wall of the positioning rod 8 along its circumference. The guide rods 9 are arranged radially along the positioning rod 8, and the number of guide rods 9 corresponds one-to-one with the number of support blocks 5.

[0044] The support block 5 and the fitting block 6 are provided with guide slots that are adapted to the guide rod 9 along their radial connection, and the end of the guide rod 9 away from the positioning rod 8 is slidably inserted into the guide slot at the corresponding position.

[0045] A tension spring 10 is sleeved on the outer side of the guide rod 9. One end of the tension spring 10 is fixed to the outer wall of the positioning rod 8, and the other end is fixed to the side wall of the fitting block 6 near the positioning rod 8.

[0046] By adopting the above technical solution, on the one hand, the positioning rod 8 is fixed to the middle of the top of the inner side of the positioning sleeve rod 2, and the guide rod 9 on its outer wall is inserted radially into the guide slot of the support block 5 and the fitting block 6. This can strictly limit the sliding direction of the support block 5 and the fitting block 6, ensuring that the two always move radially along the guide rod 9, avoiding the support block 5 from shifting or getting stuck during the sliding process, and ensuring that the support block 5 abuts against the hub with precise and consistent position, further improving the fixing accuracy. On the other hand, the tension spring 10 sleeved on the outside of the guide rod 9 is always in a stretched state and its two ends are respectively connected to the positioning rod 8 and the fitting block 6. When the movable rod 3 is reset upward after processing, the tension spring 10 will generate a contraction force, pulling the fitting block 6 and the support block 5 to reset along the guide rod 9 towards the positioning rod 8, automatically releasing the tension on the hub. There is no need for manual reset, simplifying the operation process and improving the ease of use of the equipment.

[0047] Multiple support rods 11 arranged in a ring array are fixedly connected to the bottom edge of the support seat 1, and the bottom ends of the multiple support rods 11 are fixedly connected to a support seat 12.

[0048] Multiple limiting tubes 13 arranged in a ring array are fixed to the top of the receiving seat 12. The number of limiting tubes 13 corresponds one-to-one with the number of positioning sleeve rods 2, and the limiting tubes 13 are arranged in the vertical direction.

[0049] The inner side of the limiting tube 13 is slidably connected to an internally threaded cylinder 14 with its opening facing downward, and the top end of the internally threaded cylinder 14 is fixedly connected to the bottom end of the movable rod 3.

[0050] The inner side of the internal threaded cylinder 14 is connected to a threaded post 15 by a thread. The bottom end of the threaded post 15 is rotatably connected to the corresponding position at the top of the receiving seat 12, and the bottom end of the threaded post 15 moves through to the bottom end of the receiving seat 12 and is fixedly connected to a driven gear 16.

[0051] A drive motor 17 is vertically mounted at the top center of the support 12. One end of the output shaft of the drive motor 17 extends through to the bottom end of the support 12 and is fixedly connected to a drive gear 18. Multiple driven gears 16 mesh with the outer side of the drive gear 18.

[0052] Using the above technical solution, during operation, after the drive motor 17 starts, its output shaft drives the drive gear 18 to rotate. The drive gear 18 drives multiple driven gears 16 to rotate synchronously through meshing transmission. The driven gears 16 then drive the threaded column 15, which is fixed to it, to rotate on the receiving seat 12. Since the internal threaded cylinder 14 and the threaded column 15 are connected by threads, and the internal threaded cylinder 14 is slidably connected in the limiting tube 13, the rotational motion of the threaded column 15 can be converted into the vertical lifting and lowering motion of the internal threaded cylinder 14 along the limiting tube 13, thereby driving the internal threaded cylinder 14 to rotate. The movable rod 3 slides up and down along the axial direction of the positioning sleeve rod 2. This structure realizes the automated control of the lifting and lowering of the movable rod 3, reducing the intensity of manual operation. At the same time, the meshing transmission of the driving gear 18 and multiple driven gears 16 can ensure that multiple sets of threaded columns 15, internal threaded cylinders 14 and movable rod 3 move synchronously, so that the support blocks 5 in multiple positioning sleeve rods 2 extend or reset synchronously, ensuring that the fixing force and reset state of multiple hubs are consistent, avoiding the difference in fixing effect caused by uneven manual operation force, and further improving the automation level and fixing consistency of the tooling.

[0053] Multiple support columns 19 arranged in a ring array are fixedly connected to the bottom edge of the support seat 12, and a base 20 is fixedly connected to the bottom of the multiple support columns 19.

[0054] Using the above technical solution, the support column 19 connects the support seat 12 and the base 20, reserving installation and operation space for the driven gear 16 and the driving gear 18 at the bottom of the support seat 12.

[0055] The outer walls of the internally threaded cylinder 14 are integrally formed with limit strips 21 on both sides. The inner walls of the limit tube 13 are provided with limit grooves 22 that are adapted to the limit strips 21 on both sides. The limit strips 21 on both sides are slidably connected to the limit grooves 22 on both sides respectively.

[0056] By adopting the above technical solution, the limiting strip 21 on the outer wall of the internal threaded cylinder 14 is adapted to slide with the limiting groove 22 on the inner wall of the limiting tube 13, which restricts the circumferential rotation of the internal threaded cylinder 14, ensures that it only moves up and down along the axial direction of the limiting tube 13, avoids the internal threaded cylinder 14 from rotating with the threaded column 15, and ensures that the movable rod 3 stably drives the support block 5 to move.

[0057] The bottom outer side of the positioning sleeve rod 2 is integrally formed with a fixing ring 23. The fixing ring 23 is detachably fixed to the top surface of the bearing seat 1 by a plurality of internal hexagon screws evenly distributed along its circumference.

[0058] The top center of the internal threaded cylinder 14 has a slot that matches the bottom end of the movable rod 3. The bottom end of the movable rod 3 is inserted into the slot and fixed by a radially inserted pin.

[0059] Using the above technical solution, the top of the internal threaded cylinder 14 is fixed with a slotted pin to fix the movable rod 3, and the positioning sleeve 2 is detachably connected to the bearing seat 1 by the fixing ring 23 at the bottom of the outer side and the internal hexagon screw. During maintenance, it is only necessary to first remove the pin to disconnect the movable rod 3 from the internal threaded cylinder 14, and then remove the screw on the fixing ring 23 to easily remove the positioning sleeve 2 and the movable rod 3. There is no need for complicated step-by-step operations, which greatly simplifies the maintenance process.

[0060] Working principle:

[0061] After the hub to be processed is fitted onto the outside of the positioning sleeve 2, the drive motor 17 starts and drives multiple driven gears 16 and threaded column 15 to rotate synchronously through the meshing transmission of the drive gear 18. When the threaded column 15 rotates, the internal threaded cylinder 14 connected to the thread descends vertically under the anti-rotation guidance of the limiting tube 13 and the limiting strip 21, driving the movable rod 3 to move downward along the axial direction of the positioning sleeve 2. The pushing block 4 on the outer wall of the movable rod 3 moves downward accordingly, generating radial thrust through the reverse adaptation inclined surface transmission with the fitting block 6, pushing the tensioning block 5 to slide outward along the radial guide hole of the positioning sleeve 2 until the protruding end of the tensioning block 5 tightly abuts against the inner wall of the hub to be processed, completing the hub fixing. After processing, the drive motor 17 rotates in the reverse direction, the internal threaded cylinder 14 drives the movable rod 3 to reset upward, and the fitting block 6 drives the tensioning block 5 to retract under the reset pulling force of the tension spring 10, releasing the hub fixing, and the processed hub can be removed.

[0062] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
