Description

Technical Field

[0001] This utility model relates to the field of machining technology, and in particular to a quick-change seat for a spinning wheel. Background Technology

[0002] Currently, in the use of spinning machines, the installation and positioning of the spinning rollers typically employs a transition fit between the shaft and the hole. However, this method presents several inconveniences when the spinning rollers need to be frequently disassembled and replaced.

[0003] Because the spinning rollers need to be replaced frequently during the spinning process, sometimes more than ten times a day, the traditional transition fit installation method is not only difficult to disassemble and assemble, but also has the problem of inaccurate positioning. Specifically, when the fit clearance is too large, the spinning roller is prone to displacement during processing, resulting in inaccurate positioning, which in turn damages related parts and affects spinning accuracy and workpiece quality. On the other hand, when the fit clearance is too small, the disassembly and assembly of the spinning roller becomes extremely difficult, increasing the labor intensity of operators, prolonging auxiliary work time, and reducing production efficiency.

[0004] To address the aforementioned problems, this utility model proposes a quick-change spinner. Utility Model Content

[0005] The purpose of this utility model is to solve the shortcomings of the existing technology, such as the low efficiency of disassembling and assembling the spinning wheel and the poor installation effect, which easily affects the processing quality of the workpiece, in the traditional installation method. Therefore, a quick-change seat for the spinning wheel is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A quick-change spinner, comprising:

[0008] A spinning wheel holder, wherein the spinning wheel holder is sleeved on one end of a spinning wheel shaft, and a spinning wheel is fixedly installed on one end of the spinning wheel holder by bolts; the spinning wheel is used to spin the parts.

[0009] It also includes multiple inner conical sleeves, each with an arc-shaped cross section. The multiple inner conical sleeves are evenly arranged on the outer circumferential wall of the spinning wheel shaft, and each of the multiple inner conical sleeves is located between the spinning wheel shaft and the spinning wheel seat. Each of the multiple inner conical sleeves mates with the inner wall of the spinning wheel seat, which is used to complete the quick installation and disassembly of the spinning wheel seat.

[0010] It also includes a fixing component for fixing the spinning wheel seat to multiple inner conical sleeves.

[0011] In one possible design, the fixing assembly includes multiple mounting holes at one end of the spinning wheel seat, with multiple screws passing through each of the mounting holes. Each of the multiple inner conical sleeves has a threaded hole on one side, with each threaded hole corresponding to a corresponding mounting hole. One end of each of the multiple screws is threaded to the inner wall of the corresponding threaded hole, for locking and fixing the spinning wheel seat and the multiple inner conical sleeves.

[0012] In one possible design, the outer walls of the multiple inner conical sleeves are provided with continuous first conical protrusions, and the inner wall of the spinning wheel seat is provided with corresponding second conical protrusions. The multiple first conical protrusions cooperate with the second conical protrusions to complete the mutual contact between the spinning wheel seat and the multiple inner conical sleeves, thereby locking the spinning wheel seat onto the spinning wheel shaft.

[0013] In one possible design, each of the multiple inner conical sleeves has two mounting slots on the side facing the screw. Each of the multiple mounting slots is equipped with a spring. One end of each spring abuts against the inner wall of the corresponding mounting slot, and the other end of each spring abuts against the inner wall of the spinning wheel seat. The multiple springs are used to push the corresponding inner conical sleeve to move away from the screw when the corresponding screw is loosened.

[0014] In one possible design, a positioning ring is fixedly fitted on the outer wall of the spinning wheel shaft. The positioning ring is made of spring steel. The arc-shaped inner walls of the multiple inner conical sleeves are provided with positioning grooves. The positioning ring slides in cooperation with the inner walls of the multiple positioning grooves to abut against the inner wall of the multiple inner conical sleeves tightly against the inner wall of the spinning wheel seat.

[0015] In one possible design, the width of each of the locating grooves is greater than the thickness of the locating ring to ensure that the multiple inner conical sleeves can move axially along the spinning wheel shaft when locked by screws.

[0016] In this application, during use, the user can place multiple springs into their respective mounting slots, then assemble multiple inner conical sleeves into a ring and pre-set them inside the spinning wheel seat. During pre-setting, ensure that multiple threaded holes are aligned with their corresponding mounting holes. Then, screws can be passed through the mounting holes and screwed into the threaded holes to complete the pre-installation of the multiple inner conical sleeves. After pre-installation, ensure that one end of the spring inside each inner conical sleeve abuts against the inner wall of the spinning wheel seat. Next, the user can place the spinning wheel seat onto the outer wall of the spinning wheel shaft. During installation, ensure that the multiple inner conical sleeves are positioned between the spinning wheel seat and the spinning wheel shaft until the locating ring engages with the multiple locating slots. The user can then continue to rotate the screws until they are tightened, thus fixing the spinning wheel seat to the multiple inner conical sleeves. When the screws are tightened... Multiple inner conical sleeves will move slightly towards the screw within the spinning wheel seat. At this time, the first conical protrusion on the outer wall of the inner conical sleeve will abut against the second conical protrusion on the inner wall of the spinning wheel seat, thereby locking the spinning wheel seat onto the spinning wheel shaft. Then, the user can install the spinning wheel on one end of the spinning wheel seat with bolts, and then use the spinning wheel to spin parts. When the user needs to replace the spinning wheel, the user only needs to remove multiple screws. As the screws are loosened, the springs in multiple mounting slots can push the corresponding inner conical sleeves to move away from the screws, thereby quickly releasing the abutting and squeezing effect between the spinning wheel seat and the multiple inner conical sleeves. This allows for rapid separation of the spinning wheel seat and the multiple inner conical sleeves, which is beneficial for improving the disassembly efficiency of the spinning wheel and facilitating equipment maintenance.

[0017] Beneficial effects: In this utility model, the quick-change seat for spinning rollers achieves rapid installation and disassembly of the spinning roller seat by using the cooperation between the inner conical sleeve and the spinning roller seat and the locking of screws; users can easily complete the installation and disassembly of the spinning roller seat by simply operating the screws, which greatly improves the efficiency of installation and disassembly and reduces the labor intensity of workers.

[0018] In this utility model, the quick-change seat for spinning wheel ensures that the spinning wheel seat can fit tightly against the spinning wheel shaft during installation by having the first conical protrusion on the outer wall of the inner conical sleeve abut against the second conical protrusion on the inner wall of the spinning wheel seat. This effectively avoids the problem of reduced spinning processing quality and precision caused by loosening in traditional fixing methods.

[0019] In this utility model, the quick-change seat for spinning rollers reduces production costs by adopting standard parts and modular design, making it easy for users to replace or upgrade according to actual needs. At the same time, its structural design is reasonable, the connection between each component is tight and easy to maintain, reducing the complexity of equipment maintenance and lowering maintenance costs.

[0020] In this invention, the quick-change spinner seat achieves rapid assembly and disassembly through the ingenious cooperation between the inner conical sleeve and the spinner seat, and the screw locking, greatly improving efficiency and reducing the burden on workers. Its conical protrusion design ensures a tight fit between the spinner seat and the shaft, avoiding processing quality problems caused by loosening. In addition, by adopting standard parts and modular design, not only is the cost reduced, but it also facilitates users to replace and upgrade as needed. Moreover, the reasonable structural design, tight connection, and easy maintenance effectively reduce maintenance complexity and cost, demonstrating excellent performance and practicality.

[0026] 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.

[0027] Example 1: Refer to Figure 1-4 A quick-change seat includes: a spinning wheel 1, a spinning wheel seat 2, a spinning wheel shaft 3, multiple inner conical sleeves 4, and a fixing assembly.

[0028] In this embodiment, the spinning wheel seat 2 is sleeved on one end of the spinning wheel shaft 3, and the spinning wheel 1 is fixedly installed on one end of the spinning wheel seat 2 by bolts. The spinning wheel 1 is used to spin the parts.

[0029] Furthermore, in this embodiment, multiple inner conical sleeves 4 are evenly arranged on the outer circumference of the spinning wheel shaft 3. These inner conical sleeves 4 all have arc-shaped cross-sections and are located between the spinning wheel shaft 3 and the spinning wheel seat 2. The design of the inner conical sleeves 4 allows them to mate with the inner wall of the spinning wheel seat 2, thereby enabling quick installation and disassembly of the spinning wheel seat 2. The spinning wheel seat 2, the spinning wheel shaft 3, and the multiple inner conical sleeves 4 are all made of tempered steel.

[0030] To secure the spinning wheel seat 2 to the multiple inner conical sleeves 4, this embodiment employs a fixing assembly. The fixing assembly includes multiple mounting holes 7 at one end of the spinning wheel seat 2, each hole 7 containing multiple screws 6. Simultaneously, each inner conical sleeve 4 has a threaded hole 8 on one side, corresponding to the respective mounting hole 7. When one end of the screw 6 is threaded into the inner wall of the corresponding threaded hole 8, the spinning wheel seat 2 and the multiple inner conical sleeves 4 are locked and secured.

[0031] Furthermore, in this embodiment, the outer walls of the multiple inner conical sleeves 4 are provided with continuous first conical protrusions, while the inner wall of the spinning wheel seat 2 is provided with corresponding second conical protrusions. These first and second conical protrusions cooperate with each other, so that the spinning wheel seat 2 and the multiple inner conical sleeves 4 can abut against each other, thereby locking the spinning wheel seat 2 onto the spinning wheel shaft 3.

[0032] Furthermore, to facilitate disassembly and installation, this embodiment also features mounting grooves 9 on the side of the multiple inner conical sleeves 4 facing the screw 6, and a spring 10 is installed inside the mounting groove 9. The spring 10 is made of spring steel, with one end abutting against the inner wall of one side of the mounting groove 9 and the other end abutting against the inner wall of the spinning wheel seat 2. When the screw 6 is loosened, the spring 10 pushes the corresponding inner conical sleeve 4 to move away from the screw 6, thereby facilitating disassembly.

[0033] This application can be used in the field of machining technology, or in other fields applicable to this application.

[0034] Example 2: Reference Figure 2 , 3 4. Improvement based on Example 1: A quick-change seat for a spinning wheel, which is applied to the field of machining technology;

[0035] In this embodiment, a positioning ring 5, made of spring steel, is fixedly fitted onto the outer wall of the spinning wheel shaft 3. Simultaneously, positioning grooves 11 are formed on the arc-shaped inner walls of multiple inner conical sleeves 4, and the positioning ring 5 slides into the inner walls of these grooves 11. This design ensures that the multiple inner conical sleeves 4 are tightly fitted against the inner wall of the spinning wheel seat 2, thereby improving the stability and firmness of the installation.

[0036] It is worth noting that in this embodiment, the width of each of the multiple positioning grooves 11 is slightly greater than the thickness of the positioning ring 5. This design is to ensure that the multiple inner conical sleeves 4 can move slightly axially along the spinning wheel shaft 3 when locked by the screws 6, thereby adapting to different installation requirements.

[0037] The working principle and usage process of this technical solution are as follows: During use, the user can place multiple springs 10 into their respective mounting slots 9. Then, multiple inner conical sleeves 4 can be assembled into a ring and pre-set inside the spinning wheel seat 2. During pre-setting, ensure that multiple threaded holes 8 are aligned with their corresponding mounting holes 7. Then, screws 6 can be passed through the mounting holes 7 and screwed into the threaded holes 8 to complete the pre-installation of the multiple inner conical sleeves 4. After pre-installation, ensure that one end of the inner spring 10 of each inner conical sleeve 4 can abut against the inner wall of the spinning wheel seat 2. Afterward, the user can fit the spinning wheel seat 2 onto the outer wall of the spinning wheel shaft 3. During installation, ensure that the multiple inner conical sleeves 4 are located between the spinning wheel seat 2 and the spinning wheel shaft 3, until the positioning ring 5 is engaged inside the multiple positioning slots 11. Then, the user can continue to rotate the screws 6 until they are tightened, thus fixing the spinning wheel seat 2 to the multiple inner conical sleeves 4. When screw 6 is tightened, multiple inner conical sleeves 4 will move slightly towards screw 6 within the spinning wheel seat 2. At this time, the first conical protrusion on the outer wall of the inner conical sleeve 4 will abut against the second conical protrusion on the inner wall of the spinning wheel seat 2, thereby locking the spinning wheel seat 2 onto the spinning wheel shaft 3. Afterwards, the user can install the spinning wheel 1 at one end of the spinning wheel seat 2 with bolts, and then use the spinning wheel 1 to spin parts. When the user needs to replace the spinning wheel 1, the user only needs to remove multiple screws 6. As the screws 6 are loosened, the springs 10 in multiple mounting slots 9 can push the corresponding inner conical sleeves 4 to move away from the screws 6, thereby quickly releasing the abutting and squeezing effect between the spinning wheel seat 2 and multiple inner conical sleeves 4, realizing the rapid separation of the spinning wheel seat 2 and multiple inner conical sleeves 4, which is beneficial to improving the disassembly efficiency of the spinning wheel 1 and facilitating equipment maintenance.

[0038] 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.
