[0043] The utility model provides a spring sampling fixture.

[0044] See also Figures 1 to 3 In one embodiment of the utility model, the spring sampling jig includes a jig shell 10, a winding member 20 and a driving assembly 30, the jig shell 10 has an installation space 10a; the winding member 20 is rotatably connected to the outer wall of the jig shell 10; the driving assembly 30 includes a transmission member 31 and a driving member 32, the transmission member 31 is installed in the installation space 10a, and one end of the transmission member 31 is transmission-connected to the winding member 20; the driving member 32 is installed on the outer wall of the jig shell 10, and extends into the installation space 10a and is transmission-connected to the other end of the transmission member 31; wherein the driving member 32 drives the transmission member 31 to drive the winding member 20 to rotate, so that the steel wire is wound around the winding member 20.

[0045] Start the driving member 32 so that the driving member 32 can drive the winding member 20 to rotate through the transmission member 31, so that the steel wire discharged from the discharging mechanism can be directly wound into a spring through the rotating winding member 20. In this way, the transmission connection method between the transmission member 31 and the winding member 20 makes the force transmission of the driving component 30 more direct and efficient, thereby significantly accelerating the steel wire winding speed and further improving the sampling efficiency of the spring.

[0046] The fixture realizes precise rotation connection of the winding member 20 through its unique structural design, optimizes the winding process, achieves a more uniform winding density, and ensures the uniformity and stability of the steel wire winding. Compared with the problems of uneven winding and low efficiency existing in the prior art, the design of the present application can effectively improve production efficiency and product quality.

[0047] The jig shell 10 has an installation space 10a for accommodating the transmission member 31 and the winding member 20. The material of the jig shell 10 can be aluminum alloy, stainless steel, etc., and has the characteristics of lightness and durability. The winding member 20 is rotatably connected to the outer wall of the jig shell 10. Specifically, the winding member 20 can be connected to the jig shell 10 through a bearing, so that the winding member 20 can rotate freely.

[0048] The transmission member 31 is installed in the installation space 10a of the jig shell 10. One end of the transmission member 31 is connected to the winding member 20 by transmission, for example, by means of gears, belts, etc. The driving member 32 is installed on the outer wall of the jig shell 10, and extends into the installation space 10a to be connected to the other end of the transmission member 31 by transmission. The driving member 32 can be a motor, a manual crank, etc.

[0049] In one embodiment, see Figures 1 to 3 The transmission member 31 includes a main gear 311 and a sub gear 312. The main gear 311 is rotatably connected in the installation space 10a and is transmission-connected to the driving member 32; the sub gear 312 is rotatably connected in the installation space 10a and is meshed with the main gear 311; the sub gear 312 is transmission-connected to the winding member 20; and the diameter of the main gear 311 is greater than the diameter of the sub gear 312.

[0050] Specifically, the main gear 311 and the sub-gear 312 can be rotatably connected to the inner wall of the installation space 10a through bearings; after starting the driving member 32, the driving member 32 first drives the main gear 311 to rotate, and the main gear 311 then drives the sub-gear 312 to rotate, and the sub-gear 312 then drives the winding member 20 to rotate; since the diameter of the main gear 311 is larger than the diameter of the sub-gear 312, at the same speed, the main gear 311 can transmit a larger torque, which effectively improves the power output of the transmission member 31, thereby improving the overall working efficiency of the spring sampling fixture.

[0051] This embodiment realizes effective transmission in the installation space 10a by setting the structure of the main gear 311 and the sub-gear 312, which can ensure the stability and accuracy of the transmission. In addition, the transmission connection design between the sub-gear 312 and the winding member 20 optimizes the energy transmission path, making the winding process smoother, which not only improves the product yield, but also significantly improves the product quality.

[0052] Optionally, the diameter of the main gear 311 is 2 times, 3 times, 4 times, ... the diameter of the sub-gear 312 , and specific parameters of the diameter of the main gear 311 and the diameter of the sub-gear 312 can be set according to actual conditions.

[0053] In one embodiment, see Figures 1 to 3 , the secondary gear 312 is located above the main gear 311 .

[0054] Since the secondary gear 312 is located above the main gear 311, the winding member 20 connected to the secondary gear 312 will also be correspondingly arranged at a higher position, so that the winding member 20 can wind springs of more sizes, thereby increasing the sampling versatility of the spring sampling fixture.

[0055] The design of placing the secondary gear 312 on top makes the transmission between the two more direct, reducing the energy loss caused by the long gear meshing path. This design effectively improves the efficiency of the entire gear transmission system and reduces energy consumption.

[0056] In the second embodiment, the transmission member 31 includes a first gear rack, a first gear ring, a first planetary gear and a connecting rod. The first gear rack is rotatably connected in the installation space 10a and is transmission-connected to the driving member 32; the first gear ring is connected to the first gear rack; the first planetary gear is meshingly connected in the first gear ring; one end of the connecting rod is transmission-connected to the first planetary gear, and the other end of the connecting rod is rotatably connected to the installation space 10a and is connected to the winding member 20.

[0057] Specifically, the first gear frame is provided with three connecting claws, and the three connecting claws are all connected to the first gear ring; the inner wall of the first gear ring is provided with threads, and the first planetary gear can be connected to the inner wall of the first gear ring through threaded engagement; and one end of the connecting rod is transmission-connected to the center position of the first planetary gear, and the other end of the connecting rod is rotatably connected to the inner wall of the installation space 10a through a bearing, and passes through the jig shell 10 and is connected to the winding member 20 on the outer wall of the jig shell 10.

[0058] After the driving member 32 is started, the driving member 32 drives the first gear frame to rotate, and the first gear frame drives the first gear ring to rotate. When the first gear ring rotates, it will drive the first planetary gear to revolve along the thread of the inner wall of the first gear ring, and the first planetary gear drives the connecting rod to rotate with the center of the first gear ring as the center of rotation, so that the connecting rod also drives the winding member 20 to rotate. Since the diameter of the first gear ring is larger than the diameter of the first planetary gear, the first gear ring can transmit a larger torque at the same speed, which effectively improves the power output of the transmission member 31, thereby improving the overall working efficiency of the spring sampling fixture.

[0059] The connection mode of the first gear ring and the first gear frame not only increases the compactness of the structure, but also improves the reliability of the system. The meshing connection of the first planetary gear in the first gear ring further ensures the accuracy of the transmission and reduces the cumulative error caused by inaccurate transmission.

[0060] In the third embodiment, the transmission member 31 includes a second gear rack, three second planetary gears, a sun gear and a second gear ring. The second gear rack is rotatably connected in the installation space 10a and is transmission-connected to the driving member 32; the three second planetary gears are connected to the second gear rack; the sun gear is rotatably connected in the installation space 10a and is meshingly connected to the three second planetary gears; and the sun gear is connected to the winding member 20; the second gear ring is sleeved on the three second planetary gears and is meshingly connected to the three second planetary gears.

[0061] Specifically, a convex shaft is provided at the center of each second planetary gear, and the convex shafts of the three second planetary gears are connected to the second gear rack. After starting the driving member 32, the driving member 32 drives the second gear rack to rotate, and the second gear rack drives the three second planetary gears to rotate, and then the three second planetary gears drive the middle sun gear to rotate, so that the sun gear drives the winding member 20 to rotate; since the diameter of the three second planetary gears is smaller than the diameter of the second gear rack, the second gear rack can transmit a larger torque at the same speed, which effectively improves the power output of the transmission member 31, thereby improving the overall working efficiency of the spring sampling fixture.

[0062] By setting up a transmission system of a second gear rack, three second planetary gears, a sun gear and a second gear ring, higher transmission efficiency and more stable transmission performance are achieved. The meshing connection mode of the three second planetary gears and the sun gear not only reduces energy loss, but also effectively ensures uniform distribution of force, reduces gear wear and prolongs service life.

[0063] In one embodiment, see Figures 1 to 3 The transmission member 31 also includes a coupling 313, and two ends of the coupling 313 are respectively connected to the transmission member 31 and the winding member 20.

[0064] The stability and reliability of the entire transmission system are significantly improved by adding the coupling 313 to the transmission member 31. The introduction of the coupling 313 effectively compensates for the axial, radial and angular displacements that may occur during the transmission process, making the transmission smoother and extending the service life of the transmission member 31 and the winding member 20.

[0065] In one embodiment, see Figures 1 to 3 The winding member 20 includes a clamping mechanism 21 and a winding shaft 22, and the clamping mechanism 21 is connected to the transmission member 31; the clamping mechanism 21 clamps the winding shaft 22 at one end away from the transmission member 31, and the winding shaft 22 is used for winding the steel wire.

[0066] The clamping mechanism 21 includes a pair of clamping arms and a driving component. The clamping arms are symmetrically arranged on both sides of the winding member 20 for clamping the winding shaft 22. The driving component is used to drive the clamping arms to close and open, thereby achieving the fixing and release of the winding shaft 22. The structure and size of the winding shaft 22 can be designed according to actual needs to meet the winding requirements of steel wires of different specifications.

[0067] In this embodiment, the connection between the clamping mechanism 21 and the transmission member 31 can be threaded, welded or snap-fitted to ensure the stability and reliability of the connection. At the same time, the material and shape of the clamping arm can be adjusted according to the actual application scenario to improve the applicability of the winding member 20.

[0068] The driving component keeps the clamping arm in a closed state, the winding shaft 22 starts to rotate, and the steel wire is gradually wound on the winding shaft 22. After the winding is completed, the driving component drives the clamping arm to open, releases the winding shaft 22, and takes out the wound steel wire. A new winding shaft 22 is replaced, and the above steps are repeated to achieve continuous winding.

[0069] The connection method between the clamping mechanism 21 and the transmission member 31 designed in the present application realizes automation and high efficiency of the winding process. The clamping mechanism 21 is arranged at the end away from the transmission member 31, which ensures the stability of the winding shaft 22 when rotating at high speed, reduces the swing of the steel wire during the winding process, and thus significantly improves the winding efficiency and the quality of the steel wire roll.

[0070] In one embodiment, see Figures 1 to 3 The outer wall of the winding shaft 22 is provided with a winding thread 22a.

[0071] The winding shaft 22 in this embodiment mainly includes an axis body, shaft heads arranged at both ends of the axis body, and an outer wall surrounding the axis body. The axis body is made of high-strength steel material to ensure stability and durability during high-speed rotation. The shaft head is made of aluminum alloy material to reduce the overall weight and facilitate operation. A winding thread 22a is provided on the outer wall of the winding shaft 22. The winding thread 22a is a spiral groove, and the depth and spacing of the groove are adjusted according to the specifications and material of the wound object.

[0072] When the steel wire is placed on the winding shaft 22, the winding thread 22a can make the winding article closely fit on the outer wall to prevent sliding during high-speed rotation. In addition, the winding thread 22a can also make the winding article keep neat during the winding process to avoid crossing, disorder and other phenomena.

[0073] In one embodiment, see Figures 1 to 3 The driving member 32 includes a rotating shaft 321 and a handle 322. One end of the rotating shaft 321 is rotatably connected to the outer wall of the fixture shell 10, and extends into the installation space 10a to be transmission-connected to the transmission member 31; the handle 322 is connected to one end of the rotating shaft 321 away from the fixture shell 10; the circumferential outer wall of the handle 322 is provided with wear-resistant grooves.

[0074] The rotating shaft 321 adopts a standard bearing, one end of which is connected to the outer wall of the jig shell 10 by a thread, and the other end extends into the installation space 10a. A fixing seat is provided at a corresponding position on the outer wall of the jig shell 10 for fixing the rotating shaft 321. The handle 322 is connected to the end of the rotating shaft 321 away from the jig shell 10, and adopts a snap-on structure for easy installation and disassembly. The circumferential outer wall of the handle 322 is provided with wear-resistant grooves to increase friction and improve the feel during operation. The operator holds the handle 322, and drives the rotating shaft 321 to rotate by rotating the handle 322, thereby making the transmission member 31 work and completing the corresponding operation.

[0075] The structural design of the rotating shaft 321 and the handle 322 makes it more convenient and labor-saving for the operator to perform rotational driving, and the operator can drive the rotating shaft 321 to rotate through the handle 322 according to the actual situation, so that the spring sampling fixture can sample more accurately. The circumferential outer wall of the handle 322 is provided with wear-resistant grooves, which not only increases the friction between the handle 322 and the operator's hand, but also improves the stability and safety of the operation.

[0076] In one embodiment, see Figures 1 to 3 The driving member 32 is a driving motor, which is mounted on the outer wall of the fixture shell 10 , and the output shaft of the driving motor is connected to the transmission member 31 .

[0077] Compared with the conventional technology, the utility model greatly improves the integration and space utilization of the equipment by installing the driving motor on the outer wall of the fixture housing 10. The output shaft of the driving motor is connected to the transmission member 31 in a transmission manner, realizing efficient and accurate power transmission, so that the entire device has higher stability and reliability during operation.

[0078] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention.
