Description

Technical Field

[0001] This utility model relates to the field of machining tooling, and in particular to a winding mechanism. Background Technology

[0002] In a cooling system, a capillary tube is typically located between the condenser and the evaporator. Its main function is to throttle and reduce the pressure of the refrigerant. The refrigerant exiting the condenser is a high-pressure liquid. As it passes through the capillary tube, the small inner diameter creates significant resistance, reducing the refrigerant's pressure and temperature. This allows the refrigerant to evaporate and absorb heat at a lower temperature and pressure in the evaporator, thus achieving a cooling effect. To minimize the space occupied by the capillary tube, its central portion is usually wound into multiple loops.

[0003] Currently, there are some winding methods where workers manually pull the capillary tube and wind it onto different objects. However, because the specifications of the objects to be wound are not fixed, the diameter of the coil after the capillary tube is wound is inconsistent. More seriously, because the workers use their hands to pull and stretch the capillary tube, the diameter of the capillary tube is stretched and errors occur, which in turn affects the throttling and pressure reduction effect of the capillary tube.

[0004] Therefore, there is an urgent need for a winding mechanism that can solve the problem of capillary diameter deviation caused by manual winding and achieve uniform winding of capillary onto the workpiece to be wound. Utility Model Content

[0005] The purpose of this invention is to provide a winding mechanism that can solve the problem of capillary diameter deviation caused by manual winding, and achieve uniform winding of capillary onto the workpiece to be wound.

[0006] Based on the above concept, the technical solution adopted by this utility model is as follows:

[0007] A winding mechanism, comprising:

[0008] The base is used to secure one end of the workpiece to be wrapped.

[0009] A winding column is installed on the base;

[0010] The rotating assembly includes a rotating component and an auxiliary component. The rotating component is rotatably connected to the winding column. The auxiliary component is provided on the side of the rotating component facing the base. The auxiliary component and the outer peripheral surface of the winding column allow the workpiece to be wound to pass through. The auxiliary component is used to drive the workpiece to be wound to wind around the winding column.

[0011] As an optional feature of the winding mechanism, the distance between the auxiliary component and the outer circumferential surface of the winding column is greater than or equal to the outer diameter of the component to be wound.

[0012] As an alternative to this winding mechanism, the rotating component and the auxiliary component are detachably connected;

[0013] And / or, the position of the auxiliary component on the rotating component is adjustable radially along the winding column;

[0014] And / or, the rotating component is capable of moving axially along the winding column.

[0015] As an alternative to this winding mechanism, the rotating component includes:

[0016] A rotating part, which is rotatably connected to the winding column;

[0017] A gripping part, which is connected to the rotating part, is used to drive the rotating part to rotate.

[0018] As an alternative to the winding mechanism, the rotating part is an annular column, which is rotatably sleeved on the outside of the winding column, and the auxiliary component is disposed on the axial end face of the rotating part.

[0019] As an alternative to the winding mechanism, the gripping part includes a grip handle and a connecting body. The grip handle is connected to the rotating part through the connecting body and is used to drive the rotating part to rotate.

[0020] The grip extends axially along the rotating part, and the connected body extends radially along the rotating part.

[0021] As an optional solution for the winding mechanism, the base is provided with a fixing groove for fixing the workpiece to be wound.

[0022] As an alternative to the winding mechanism, the base includes a fixing member and a main body, the fixing member being detachably connected to the main body, and the fixing groove being provided on the fixing member.

[0023] As an alternative to the winding mechanism, a scale line is provided on the base next to the fixing groove and along the length of the fixing groove.

[0024] As an optional solution for the winding mechanism, the fixing member is provided with a first clearance notch arranged along the circumference of the winding column, and a rotation gap is formed between the fixing member and the winding column at intervals.

[0025] Alternatively, the fixing member abuts against the winding post, and the winding post extends beyond the rotating member towards the base by a dimension greater than the radius of the part to be wound but smaller than the diameter of the part to be wound.

[0026] The beneficial effects of this utility model are as follows:

[0027] This utility model proposes a winding mechanism in which a winding column is connected to a base, a rotating component is rotatably connected to the winding column, and an auxiliary component is provided on the side of the rotating component facing the base. The auxiliary component and the outer circumferential surface of the winding column allow the workpiece to be wound to pass through. Under the drive of the rotating component, the auxiliary component can wind the workpiece to be wound onto the winding column, so that the size of the coil after each winding is the same. At the same time, it can make the force on the workpiece winding onto the winding column more uniform, avoiding the situation where uneven force on the workpiece during winding affects subsequent use.

It should be understood that the specific embodiments described herein are merely for explaining this invention and are not intended to limit it.

[0040] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0041] like Figure 1As shown, this embodiment provides a winding mechanism including a base 1, a winding post 2, and a rotating assembly 3. The base 1 is used to fix one end of the workpiece to be wound, and the winding post 2 is disposed on the base 1. The rotating assembly 3 includes a rotating component 31 and an auxiliary component 32. The rotating component 31 is rotatably connected to the winding post 2, and the auxiliary component 32 is disposed on the side of the rotating component 31 facing the base 1. The workpiece to be wound can pass through between the auxiliary component 32 and the outer circumferential surface of the winding post 2. When the rotating component 31 is rotated, the auxiliary component 32 disposed on the rotating component 31 also moves circumferentially with the rotating component 31. At this time, the auxiliary component 32 can drive the workpiece to be wound to be wound onto the winding post 2. Since the workpiece to be wound is driven by the auxiliary component 32 rather than manually wound, not only is the coil size after each winding the same, but it also avoids uneven force when manually winding and pulling the workpiece, which would cause uneven force on the workpiece and thus avoid damage to the workpiece body and errors in subsequent use.

[0042] In this embodiment, the component to be wound is a capillary tube. In other embodiments, the component to be wound can also be a wire, metal wire, or other structures.

[0043] To achieve multi-turn winding of the capillary tube, the rotating component 31 can move along the axial direction of the winding column 2. In the initial state, the rotating component 3 is in the initial position under the action of gravity. When the workpiece to be wound is wound on the winding column 2, the bottom end of the rotating component 3 abuts against the workpiece to be wound, so that the workpiece to be wound can be wound evenly on the winding column 2 in a layered manner, while the height of the workpiece relative to the base 1 gradually increases.

[0044] Optionally, the winding column 2 can be integrally formed with the base 1 or can be detachably connected to the base 1. In this embodiment, the winding column 2 and the base 1 are detachably connected. The above-mentioned arrangement allows the winding column 2 to be replaced as required when there are requirements for the size of the capillary after winding. At the same time, the detachable connection between the winding column 2 and the base 1 also facilitates the storage of the winding mechanism.

[0045] Optionally, the distance between the auxiliary member 32 and the outer peripheral surface of the winding post 2 is greater than or equal to the outer diameter of the capillary, allowing the winding member to pass smoothly between the winding post 2 and the auxiliary member 32, thereby enabling the capillary to be driven by the auxiliary member 32 and wound onto the winding post 2. In this embodiment, as... Figure 1 and Figure 2As shown, the auxiliary component 32 is set as one, and the rotating component 31 is provided with a first mounting hole on the side facing the base 1. The auxiliary component 32 is connected to the first mounting hole. The minimum distance between the auxiliary component 32 and the outer peripheral surface of the winding column 2 is slightly greater than the outer diameter of the capillary tube, so that the capillary tube can be wound on the winding column 2 under the drive of the auxiliary component 32. At the same time, since the minimum distance between the auxiliary component 32 and the outer peripheral surface of the winding column 2 is slightly greater than the outer diameter of the capillary tube, abnormal capillary tubes can also be filtered, so that the capillary tubes wound on the winding column 2 are all capillary tubes that can work normally, thereby improving the winding efficiency of the winding mechanism.

[0046] Optionally, the auxiliary component 32 and the rotating component 31 can be integrally formed, detachably connected, or fixedly connected. In this embodiment, the auxiliary component 32 and the rotating component 31 are detachably connected, which makes it easy to change the specifications of the auxiliary component 32 so that the winding mechanism can drive capillaries of various sizes and wind the capillaries onto the winding column 2.

[0047] Optionally, the position of the auxiliary member 32 on the rotating member 31 is adjustable radially along the rotating member 31. In some embodiments, at least one auxiliary member 32 is provided, and a plurality of second mounting holes are provided radially and circumferentially along the side of the rotating member 31 facing the base 1. At least one auxiliary member 32 can be connected to any one of the plurality of second mounting holes to accommodate the winding of capillary tubes of various specifications, thereby improving the versatility of the winding mechanism. In other embodiments, at least one auxiliary member 32 is provided, and a plurality of elongated mounting holes are provided circumferentially along the side of the rotating member 31 facing the base 1, wherein any elongated mounting hole extends radially along the rotating member 31. At least one auxiliary member 32 can be connected to any position of any elongated hole to accommodate the winding of tapes of various specifications, thereby improving the versatility of the winding mechanism. In other embodiments, the auxiliary member 32 and the rotating member 31 can be designed in any form, as long as the position of the auxiliary member 32 on the rotating member 31 is adjustable radially along the rotating member 31, and will not be described in detail further.

[0048] Specifically, such as Figure 1 and Figure 2 As shown, in this embodiment, the rotating member 31 includes a rotating part 311 and a holding part 312. The rotating part 311 is rotatably connected to the winding column 2, and the holding part 312 is connected to the rotating part 311, so that the holding part 312 can drive the rotating part 311 to rotate. The above arrangement allows the operator to hold the holding part 312 to drive the rotating part 311, thereby causing the auxiliary member 32 to drive the workpiece to be wound onto the winding column 2, so that the workpiece can be wound evenly onto the winding column 2.

[0049] More specifically, such as Figure 1 and Figure 2As shown, in this embodiment, the rotating part 311 is an annular column. The rotating part 311 is rotatably sleeved on the outside of the winding column 2. The auxiliary member 32 is disposed on the axial end face of the rotating part 311. The rotating part 311 can rotate relative to the winding column 2 as an axis, so that the auxiliary member 32 rotates around the winding column 2. This allows the capillary tube to be evenly wound on the winding column 2 under the drive of the auxiliary member 32, avoiding the situation where the winding member is affected by uneven force due to winding, thus affecting normal use.

[0050] Specifically, such as Figure 1 and Figure 2 As shown, in this embodiment, the grip portion 312 includes a grip handle 3121 and a connecting body 3122. The grip handle 3121 is connected to the rotating portion 311 via the connecting body 3122, allowing the grip handle 3121 to push the rotating portion 311. The grip handle 3121 extends axially along the rotating portion 311, and the connecting body 3122 extends radially along the rotating portion 311. The design of the grip handle 3121 facilitates the application of force to the rotating portion 311. Furthermore, the axial extension of the grip handle 3121 conforms to ergonomic principles, allowing the hand to naturally push along the axial direction when gripping, much like pushing a rod-shaped object. The direction of the force applied by the hand is consistent with the direction of the grip handle 3121, making operation easier and more comfortable. The connecting body 3122 extends radially along the rotating part 311, which can effectively transmit the force on the grip handle 3121 to the rotating part 311. When the grip handle 3121 is pushed, due to the radial extension of the connecting body 3122, the force can be transmitted to the rotating part 311 at a more reasonable angle and path, reducing the loss of force. At the same time, based on the lever principle, the above arrangement can also achieve the winding of the capillary with less force.

[0051] In some other embodiments, the grip portion 312 includes only a grip handle 3121, which is connected to the rotating portion 311. The grip handle 3121 extends along the axial direction of the rotating portion 311, which can also drive the rotating portion 311 to rotate, thereby driving the winding member to wind onto the winding column 2 to achieve uniform winding of the capillary.

[0052] In some other embodiments, the grip portion 312 only includes a grip handle 3121. The grip handle 3121 is connected to the rotating portion 311. At the same time, the grip handle 3121 extends radially along the rotating portion 311, which can also drive the rotating portion 311 to rotate, thereby driving the winding member to wind around the winding column 2 to achieve uniform winding of the capillary.

[0053] Specifically, such as Figures 1-3As shown, in this embodiment, a fixing groove 111 is provided on the base 1. The fixing groove 111 can fix the capillary tube, so that one free end of the capillary tube is fixed, and the rotating component 3 can more easily wind the capillary tube on the other end without worrying that the winding part at the end fixed by the fixing groove 111 will fall off and affect the winding of the entire capillary tube.

[0054] Optionally, the depth of the fixing groove 111 is greater than or equal to the radius of the capillary, and the inner diameter of the fixing groove 111 is equal to or less than the outer diameter of the capillary. When the inner diameter of the fixing groove 111 is slightly smaller than the outer diameter of the part to be wound, the capillary and the fixing groove 111 are interference-fitted, allowing the capillary to be better fixed in the fixing groove 111 without being damaged. In this embodiment, the depth of the fixing groove 111 is greater than the radius of the capillary, and the inner diameter of the fixing groove 111 is equal to the outer diameter of the capillary, allowing the part to be wound to be placed more stably in the fixing groove 111. The inner diameter of the fixing groove 111 being equal to the outer diameter of the capillary ensures that the capillary and the fixing groove 111 fit tightly, making it less likely for the capillary to fall out of the fixing groove 111. In other words, the fixing groove 111 configured above can better fix the part to be wound, and at the same time, the depth of the fixing groove 111 being greater than the radius of the capillary can also provide a certain degree of protection for the capillary.

[0055] Specifically, such as Figures 1-3 As shown, in this embodiment, the base 1 includes a fixing member 11 and a main body 12. The fixing member 11 is detachably connected to the main body 12, and a fixing groove 111 is provided on the fixing member 11 for fixing one end of the capillary. The fixing member 11 can better fix the winding component. At the same time, since the fixing member 11 and the main body 12 are detachably connected, when the size of the capillary changes, the fixing member 11 can be replaced according to the size of the capillary without replacing the entire winding mechanism, making the winding mechanism more user-friendly.

[0056] Specifically, in this embodiment, a scale line is provided on the base 1 on the side of the fixing groove 111 and along the length of the fixing groove 111, so that the winding mechanism can more accurately reserve the unbent part after winding by moving the length of the capillary in the fixing groove 111 as needed.

[0057] In some embodiments, such as Figures 1-3As shown, there is a gap between the fixing member 11 and the winding column 2. This gap is a rotation gap, which is also the distance between the circumferential side wall of the winding column 2 and the outer side wall of the fixing member 11. The minimum size of the rotation gap is greater than or equal to the sum of the outer diameter of the auxiliary member 32 and the outer diameter of the capillary tube. A first clearance notch 112 is provided on the fixing member 11 along the circumference of the winding column 2. The setting of the first clearance notch 112 and the rotation gap can realize the clearance of the winding column 2, so that the winding operation of the winding mechanism can proceed smoothly.

[0058] In some other embodiments, such as Figure 4 As shown, the fixing member 11 abuts against the winding column 2. The winding column 2 extends out of the rotating member 31 towards the base 1. The dimension of the winding column 2 is greater than the radius of the capillary and smaller than the diameter of the capillary. This allows the winding column 2 to not only drive the capillary, but also to raise the overall height of the rotating component 3 after the capillary is wound around the winding column 2 at least once, thereby avoiding the fixing member 11 and enabling the winding operation of the winding mechanism to proceed smoothly.

[0059] In other embodiments, the fastener 11 can be configured in any way, as long as it can avoid the winding post 2 and allow the capillary to be smoothly wound on the winding post 2, without further elaboration.

[0060] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. 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 here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
