Description

Technical Field

[0001] This invention relates to the field of speed reducers, and in particular to a greenhouse speed reducer and its manufacturing process. Background Technology

[0002] Greenhouse speed reducers typically refer to geared motors or speed reducers used in greenhouse environments. Their core function is to convert the high-speed, low-torque output of an electric motor into the low-speed, high-torque output required by the equipment, thus meeting the power needs of various mechanical devices within the greenhouse.

[0003] Given the working environment of greenhouse speed reducers, the forward and reverse rotation function of greenhouse speed reducers is particularly important. However, existing greenhouse speed reducers generally control the forward and reverse rotation of the speed reducer through a control panel, and the speed reducer itself does not have a forward and reverse rotation selection function, which is not conducive to the convenience of actual work. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the present invention provides a greenhouse speed reducer and its manufacturing process, which has the advantages of convenient operation of the greenhouse speed reducer.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A greenhouse speed reducer, comprising: The geared motor is the driving component of the greenhouse gearbox; The speed reduction mechanism includes a speed reduction input shaft coaxially connected to the output shaft of the speed reduction motor, a speed reduction output shaft connected to an external actuator, and a speed reduction transmission assembly disposed between the speed reduction input shaft and the speed reduction output shaft; A forward / reverse rotation limiting mechanism restricts the forward and reverse rotation angles of the reduction output shaft. The controller is used to control the geared motor; The controller includes a first toggle switch and a second toggle switch; the first toggle switch is used to switch between manual mode and automatic mode; the second toggle switch is used to switch between forward and reverse rotation in manual mode.

[0006] By adopting the above technical solution, manual forward / reverse switching and automatic forward / reverse switching can be realized, making the greenhouse reducer more convenient to use.

[0007] Optionally, the forward and reverse rotation limiting mechanism includes a forward rotation limit micro switch, a reverse rotation limit micro switch, a rotating box assembly, and a trigger assembly; the rotating box assembly includes a rotating box body, a pair of trigger seats telescopically mounted on the rotating box body, and a pair of driving actuators mounted on the rotating box body; the driving actuators correspond one-to-one with the trigger seats, and the driving actuators drive the corresponding trigger seats to extend; the pair of trigger seats are respectively aligned with the trigger points of the forward rotation limit micro switch and the reverse rotation limit micro switch; the trigger assembly includes a trigger drive seat and a driving component; the deceleration output shaft drives the trigger drive seat to reciprocate and translate via the driving component; during the movement of the trigger drive seat in one direction, it abuts against one of the driving actuators, thereby causing the corresponding trigger seat to extend; during the movement of the trigger drive seat in another direction, it abuts against the other driving actuator, thereby causing the corresponding trigger seat to extend.

[0008] By adopting the above technical solution, when the reduction output shaft rotates in the forward direction, the drive component drives the trigger drive seat to move in one direction. In this direction, it will abut against one of the drive components, thereby causing the trigger seat on the corresponding side to extend. This triggers the forward limit micro switch, thereby controlling the reduction motor to stop rotating in the forward direction. When the reduction output shaft rotates in the reverse direction, the drive component drives the trigger drive seat to move in the other direction. In this direction, it will abut against another drive component, thereby causing the trigger seat on the corresponding side to extend. This triggers the reverse limit micro switch, thereby controlling the reduction motor to stop rotating in the reverse direction.

[0009] Optionally, the position of the contact point between the driving actuator and the trigger drive seat in the moving direction of the trigger drive seat can be adjusted.

[0010] By adopting the above technical solution, since the position of the contact point between the driving component and the trigger drive seat in the moving direction of the trigger drive seat can be adjusted, the time of forward and reverse rotation can be adjusted, making the greenhouse reducer more adaptable to operation.

[0011] A manufacturing process for a greenhouse speed reducer, used for assembling the speed reduction mechanism of the greenhouse speed reducer; comprising the following steps: Step S110: Install the reduction output shaft and driven gear; Step S120: Install the bearings on both sides of the reduction output shaft; Step S130: Install the oil seals on both sides of the reduction output shaft; Step S140: Install the worm gear and gear shaft; Step S150: Install the bearings on both sides of the gear shaft; Step S160: Install the oil seal covers on both sides of the gear shaft; Step S170: Use a press-fitting machine to press the driven gear and bearing onto the worm gear to form a worm gear assembly; Step S180: Install the worm gear assembly; Step S190: Install the motor gear and the reduction input shaft into the input socket to form the input module; Step S200: Install the input module.

[0012] Optionally, the press-fitting machine includes: A worm gear feeding / discharging device is used to restrict the vertical worm gear and move it horizontally for feeding and discharging. The key pressing device is located at the end of the worm gear in the feeding direction and is used to press keys onto the worm gear in the opposite direction of the feeding direction. The upper bearing press-fitting device is located on the upper side of the end of the worm in the feeding direction and is used to press-fit the bearing at the upper end of the worm. The lower assembly device, located on the lower side of the end of the worm in the feeding direction, includes a driven gear pressing mechanism for pressing a driven gear at the lower end of the worm, a lower bearing pressing mechanism for pressing a bearing at the lower end of the worm, and a horizontal switching mechanism for switching the driven gear pressing mechanism and the lower bearing pressing mechanism to alternately reach directly below the worm.

[0013] By adopting the above technical solution, the worm feeding device drives the worm to move horizontally for feeding, then the key pressing device presses the key horizontally into the keyway of the worm, then the upper bearing pressing device presses the bearing on the upper end of the worm, then the driven gear pressing mechanism presses the driven gear on the lower end of the worm, then the lower bearing pressing mechanism presses the bearing on the lower end of the worm, and finally the worm feeding device drives the assembled worm component to move horizontally for feeding. In this way, the operator only needs to complete the feeding of the worm and the unloading of the worm component, which greatly reduces the workload of the operator. All parts of the worm component are assembled on the same machine, which greatly improves the assembly efficiency.

[0014] Optionally, the press-fitting machine further includes: A worm gear adjustment device adjusts the worm so that its keyway is horizontally aligned with the pressing direction of the key pressing device.

[0015] By adopting the above technical solution, the worm gear adjustment device can adjust the position of the worm gear, so that the operator does not need to manually control the feeding state of the worm gear, which further reduces the workload of the operator and greatly improves the assembly efficiency.

[0016] Optionally, the worm gear adjusting device includes: The adjusting seat has an adjusting slot into which the lower end of the worm gear is inserted; Adjust the lifting mechanism to drive the adjustment seat to rise and fall; An adjusting ring seat is rotatably connected to the adjusting seat and is coaxially arranged with the adjusting slot; The ring seat rotation drive mechanism drives the adjusting ring seat to rotate one revolution. The inner cylindrical surface of the adjusting ring seat is radially elastically provided with an adjusting key block that mates with the keyway of the worm gear; the adjusting ring seat is provided with a shrinkage limiting component for keeping the adjusting key block in a retracted state; in the initial state, the adjusting key block of the adjusting ring seat is directly facing the pressing direction of the key pressing device.

[0017] By adopting the above technical solution, in the initial state, the adjusting key block is restricted to the retracted state by the retraction limiting component and the adjusting key block is facing the pressing direction of the key pressing device. In this way, the worm can smoothly pass through the adjusting ring seat from top to bottom and its lower end is inserted into the adjusting slot. Then, the retraction limiting component stops working, the adjusting key block elastically extends and abuts against the cylindrical surface of the worm, and then the ring seat rotation drive mechanism drives the adjusting ring seat to rotate one revolution and return to the initial position. During this process, the adjusting key block will enter the keyway of the worm, thereby driving the worm to rotate, so that the worm keyway and the adjusting key block are both horizontally facing the pressing direction of the key pressing device.

[0018] Optionally, the key pressing device includes a key pressing mechanism that reciprocates along the feeding direction of the worm and a reciprocating drive mechanism for driving the key pressing mechanism to reciprocate; the key pressing mechanism includes a key storage seat and a key pressing assembly for pushing the keys to move against the feeding direction of the worm; the key storage seat has a key storage groove; the length direction of the key storage groove is the same as the feeding direction of the worm and is open towards one end of the worm; a plurality of keys are horizontally stacked along the length direction of the key storage groove; the key pressing assembly drives all the keys to move towards the worm at equal intervals, so that the key closest to the worm is pressed into the keyway of the worm.

[0019] By adopting the above technical solution, during key press-fitting, the reciprocating drive mechanism drives the key press-fitting mechanism to approach the worm, and then the key press-fitting assembly pushes all the keys to move toward the worm at equal intervals, so that the key closest to the worm is pressed into the keyway of the worm. This structure is simple and the press-fitting steps are concise. At the same time, since the reciprocating drive mechanism drives the key press-fitting mechanism to move away from or closer to the worm, it can avoid interference when assembling other components, which greatly improves operability.

[0020] Optionally, the upper bearing pressing device includes a vertically lifting bearing storage seat, an upper bearing lifting drive mechanism for driving the bearing storage seat, and an upper bearing pressing mechanism; the bearing storage seat includes an upper intermediate guide post, an outer support sleeve, an upper connecting assembly, a lower connecting assembly, and a bearing limiting assembly; the upper bearing lifting drive mechanism is used to drive the outer support sleeve; the upper intermediate guide post is located at the central axis of the outer support sleeve, and the gap between the two allows the bearing to slide vertically; the upper connecting assembly is used for the separation and connection between the upper ends of the upper intermediate guide post and the outer support sleeve; the lower connecting assembly is used for the separation and connection between the lower ends of the upper intermediate guide post and the outer support sleeve; the bearing limiting assembly is used to restrict the downward sliding of the second bearing located in the gap between the upper intermediate guide post and the outer support sleeve from bottom to top; the upper bearing pressing mechanism is used to press the bearing that has left the outer support sleeve onto the upper end of the worm gear.

[0021] By adopting the above technical solution, when the bearing storage seat needs to be replenished with bearings, the upper connecting component separates the upper intermediate guide post and the outer support sleeve at their upper ends, while the lower connecting component connects the lower ends of the upper intermediate guide post and the outer support sleeve, allowing the bearing to enter the gap between the upper intermediate guide post and the outer support sleeve. When the bearing storage seat is supplied, the upper connecting component connects the upper ends of the upper intermediate guide post and the outer support sleeve, and the bearing limiting component restricts the second bearing from bottom to top within the gap between the upper intermediate guide post and the outer support sleeve. Then, the lower connecting component separates the lower ends of the upper intermediate guide post and the outer support sleeve, allowing the lowermost bearing to move away from the outer support sleeve along the upper intermediate guide post. The upper bearing pressing mechanism then presses the bearing that has moved away from the outer support sleeve onto the upper end of the worm gear. Simultaneously, since at least one of the upper and lower connecting components connects the upper intermediate guide post and the outer support sleeve, the upper bearing lifting drive mechanism can drive the entire bearing storage seat to move up or down, thus moving closer to or away from the worm gear. Therefore, while ensuring that the bearing slides smoothly in the predetermined direction, the functions of bearing storage and unloading can still be achieved.

[0022] Optionally, the driven gear pressing mechanism includes a driven gear storage base, a driven gear lifting drive assembly for driving the driven gear storage base to rise and fall vertically, and a driven gear pressing assembly; the driven gear storage base includes a driven gear storage column; a plurality of vertically stacked driven gears are sleeved on the driven gear storage column and the rotation of the driven gears is restricted; the upper end of the driven gear storage column is formed with a connecting slot for the lower end of the worm gear to be inserted; the driven gear pressing assembly is used to drive all the driven gears on the driven gear storage column to rise with equal clearance, so that the uppermost driven gear is pressed onto the lower end of the worm gear.

[0023] By adopting the above technical solution, before pressing the driven gear, the entire driven gear storage base is first raised so that the connecting slot of the driven gear storage column is fitted onto the lower end of the worm. In this way, when the driven gear is installed, the keyway of the driven gear is always aligned with the key already installed on the worm, ensuring smooth assembly and avoiding accidental collisions between the driven gear and the key during the assembly process.

For connection to the reduction motor, an input seat 13 is fixed to the reduction gearbox 11; the input seat 13 is connected to the housing of the reduction motor by bolts; the reduction input shaft 12 is rotatably connected to the input seat 13 via bearings.

[0042] refer to Figure 2 and Figure 3In order to directly control the forward and reverse rotation of the greenhouse reducer, the controller 2 includes a first toggle switch 21 and a second toggle switch 22; the first toggle switch 21 is used to switch between manual mode and automatic mode; the second toggle switch 22 is used to switch between forward and reverse rotation in manual mode.

[0043] refer to Figures 2-7 In order to limit the forward and reverse rotation angles of the deceleration output shaft 14, the controller 2 is provided with a forward and reverse rotation limiting mechanism 17. The forward and reverse rotation limiting mechanism 17 includes a forward rotation limit micro switch 172, a reverse rotation limit micro switch 173, a rotating box assembly 174, and a trigger assembly 171.

Guided by a pair of guide plates 1747, the rotating trigger screw 1714 drives the trigger drive seat 175 to move axially along the trigger rod 1752. When the trigger screw 1714 rotates forward and backward, the trigger drive seat 175 reciprocates axially along the trigger rod 1752.

[0045] refer to Figures 4-7The rotating box assembly 174 includes a rotating box body 1741, a pair of trigger seats 1743 telescopically disposed on the rotating box body 1741, and a pair of driving actuators disposed on the rotating box body 1741. The driving actuators correspond one-to-one with the trigger seats 1743, and the driving actuators drive the corresponding trigger seats 1743 to extend. The pair of trigger seats 1743 are respectively facing the trigger points of the forward rotation limit micro switch 172 and the reverse rotation limit micro switch 173. The trigger point of the forward rotation limit micro switch 172 is the first trigger point 1721; the trigger point of the reverse rotation limit micro switch 173 is the second trigger point 1731. When the trigger drive seat 175 moves in one direction, it abuts against one of the driving actuators, thereby causing the corresponding trigger seat 1743 to extend. When the trigger drive seat 175 moves in the other direction, it abuts against the other driving actuator, thereby causing the corresponding trigger seat 1743 to extend.

[0046] refer to Figures 5-7The driving components include a direct drive bar 1746 and a tension spring 1742; the direct drive bar 1746 extends horizontally within the rotating housing 1741; a pair of direct drive bars 1746 are aligned on the same straight line and parallel to the axial direction of the trigger screw 1714; side baffles 1748 are fixed to the ends of the pair of direct drive bars 1746 that are far apart from each other; the pair of side baffles 1748 are located on both sides of the moving direction of the trigger rod 1752; a pair of guide pillars 174 are fixed inside the rotating housing 1741. 11; Guide post 17411 corresponds one-to-one with trigger seat 1743 and its length direction is the same as the extension direction of trigger seat 1743; guide post 17411 is telescopically disposed on the inner end of trigger seat 1743; tension spring 1742 is sleeved on guide post 17411 and one end is fixed to the side wall of rotating box 1741, and the other end is fixed to trigger seat 1743; an L-shaped drive part 17461 is fixed to the inner end of direct drive bar 1746; drive part 17461 has a...

The engagement of the inclined surfaces causes the corresponding trigger seat 1743 to extend. When the direct drive bar 1746 retracts, the engagement of the tension spring 1742 with the active and driven inclined surfaces causes the corresponding trigger seat 1743 to retract. To limit the retraction limit of the direct drive bar 1746, a pair of inner stops 17412 are detachably fixed inside the rotating housing 1741. The inner stops 17412 correspond one-to-one with the direct drive bar 1746 and are located inside the corresponding direct drive bar 1746. Therefore, when the trigger drive seat 175 moves in one direction, the trigger rod 1752 drives the side stop plate 1748 in that direction to move, that is, the corresponding direct drive bar 1746 extends, thereby causing the corresponding trigger seat 1743 to extend and trigger the forward limit micro switch 172 or the reverse limit micro switch 173, thereby stopping the deceleration output shaft 14 from rotating forward or in reverse.

[0047] To adjust the forward and reverse rotation angles of the reduction output shaft 14, the position of the side baffle 1748 on the direct drive bar 1746 is designed to be adjustable. Specifically, the side baffle 1748 is horizontally fitted onto the direct drive bar 1746, and a limit bolt 1749 is screwed onto the upper end of the side baffle 1748. The bottom of the limit bolt 1749 abuts against the upper end face of the direct drive bar 1746. To make the movement direction of the side baffle 1748 more accurate, the side baffle 1748 is also horizontally fitted onto a pair of guide plates 1747.

The clamping mechanism includes a pair of clamping cylinders 341 arranged opposite each other. A clamping block 34 is fixed on the piston rod of the clamping cylinder 341. When the pair of clamping blocks 34 approach each other, they clamp the worm gear 15. At this time, the part of the worm gear 15 used to install the driven gear 151 and the lower bearing 153 is lower than the lower end face of the support plate 31, and the part used to install the upper bearing 153 is higher than the clamping mechanism. This facilitates the subsequent assembly of the driven gear 151, the lower bearing 153, and the upper bearing 153. In other embodiments, the clamping cylinder 341 can be replaced by other linear drive components.

In other embodiments, the key pressing cylinder 43 can be replaced by other linear drive components. To better achieve the assembly of the keys 152, the end of the key storage base 42 near the worm 15 is formed with a semi-cylindrical groove that matches the cylindrical surface where the keyway of the worm 15 is located. The opening of the semi-cylindrical groove faces the feeding direction of the worm 15 and the opening of the key storage groove 420 faces the opening of the semi-cylindrical groove.

[0057] refer to Figure 13 The upper bearing pressing device 5 includes an upper bearing pressing support platform 51, a vertically lifting bearing storage seat 54, an upper bearing lifting drive mechanism 52 for driving the bearing storage seat 54, and an upper bearing pressing mechanism; wherein four rectangular upper bearing support feet 511 are fixed on the bottom surface of the upper bearing pressing support platform 51; and a storage clearance hole 510 for the bearing storage seat 54 to pass vertically through is formed in the center of the upper bearing pressing support platform 51.

[0058] refer to Figure 13The bearing storage base 54 includes an upper intermediate guide post 541, an outer support sleeve 542, an upper connecting assembly 543, a lower connecting assembly 544, and a bearing limiting assembly 545.

The upper bearing lifting drive mechanism 52 includes a pair of upper bearing lifting drive cylinders fixed to the upper end face of the upper bearing pressing support platform 51 and a lifting connecting seat 53 fixed to the upper end of the piston rod of the pair of upper bearing lifting drive cylinders. The outer support sleeve 542 passes through the lifting connecting seat 53, and the two are fixedly connected. In other embodiments, the upper bearing lifting drive cylinders can be replaced by other linear drive components. The upper bearing lifting drive mechanism 52 is designed so that the bottom of the upper intermediate guide post 541 is vertically away from or close to the top of the worm gear, thereby achieving the switching between two states: avoiding the worm gear 15 during material feeding / discharging and pressing the upper bearing 153.

[0059] refer to Figure 13 The upper intermediate guide post 541 is located at the central axis of the outer support sleeve 542 and the gap between the two allows the bearing 153 to slide vertically; the bottom of the upper intermediate guide post 541 extends beyond the lower end face of the outer support sleeve 542 and is used to abut against the upper end of the worm gear 15, thereby improving the directional accuracy of bearing press fitting.

[0060] refer to Figure 13 The upper connecting assembly 543 is used for the separation and connection between the upper intermediate guide post 541 and the upper support sleeve 542 at their upper ends; the lower connecting assembly 544 is used for the separation and connection between the lower ends of the upper intermediate guide post 541 and the outer support sleeve 542; the bearing limiting assembly 545 is used to limit the downward sliding of the second bearing 153 located in the gap between the upper intermediate guide post 541 and the outer support sleeve 542 from bottom to top; wherein the upper connecting assembly 543 includes at least three upper connecting cylinders radially fixed to the outer cylindrical surface of the outer support sleeve 542; an upper connecting post is fixed on the piston rod of the upper connecting cylinder; the upper intermediate guide post 543 is used for the separation and connection between the upper intermediate guide post 541 and the lower support sleeve 542 at their lower ends ... The intermediate guide post 541 has multiple upper connecting holes formed on its cylindrical surface to mate with the upper connecting post; the lower connecting assembly 544 includes at least three lower connecting cylinders radially fixed to the outer cylindrical surface of the outer support sleeve 542; a lower connecting post is fixed on the piston rod of the lower connecting cylinder; the upper intermediate guide post 541 has multiple lower connecting holes formed on its cylindrical surface to mate with the lower connecting post; the bearing limiting assembly 545 includes a pair of bearing limiting cylinders oppositely arranged and fixed to the outer cylindrical surface of the outer support sleeve 542; a limiting post is fixed on the piston rod of the bearing limiting cylinder; the limiting post is used to abut against the outer cylindrical surface of the bearing 153. In other embodiments, the upper connecting cylinder, lower connecting cylinder, and bearing limiting cylinder can all be replaced by other linear drive components.

[0061] When bearing 153 is being replenished, the ends of multiple lower connecting posts are inserted into multiple lower connecting holes of the upper intermediate guide post 541. A pair of limiting posts retract, and the retraction of multiple upper connecting posts exposes the upper opening of the gap between the upper intermediate guide post 541 and the outer support sleeve 542, facilitating bearing replenishment. When bearing 153 is being press-fitted, the ends of multiple upper connecting posts are inserted into multiple lower connecting holes of the upper intermediate guide post 541. Then, a pair of limiting posts extend and abut against the second bearing 153 from bottom to top. The multiple lower connecting posts retract, allowing the bottommost bearing to slide down along the upper intermediate guide post 541 and leave the outer support sleeve 542. In this way, the upper bearing press-fitting mechanism presses the bearing 153 that has left the outer support sleeve 542 onto the upper end of the worm gear 15. Next, multiple lower connecting posts extend and re-insert into multiple lower connecting holes. A pair of limiting posts retract, allowing all the stored bearings to slide down and be blocked by the multiple lower connecting posts. Then, a pair of limiting posts extend and abut against the second bearing 153 from bottom to top, preparing for the next bearing press-fitting.

[0062] refer to Figure 13 The upper bearing press-fitting mechanism includes two upper bearing press-fitting assemblies symmetrically arranged at their center faces relative to the upper intermediate guide post 541. Each upper bearing press-fitting assembly includes an upper bearing press-fitting electric cylinder 55 fixed to the upper end face of the upper bearing press-fitting support platform 51 and a press-fitting block assembly 56 fixed to the lower end of the piston rod of the upper bearing press-fitting electric cylinder 55. The press-fitting block assembly 56 includes a press-fitting block telescopic seat 561 fixed to the lower end of the piston rod of the upper bearing press-fitting electric cylinder 55, a press-fitting block 563 telescopically disposed within the press-fitting block telescopic seat 561, and a press-fitting block telescopic cylinder 562. The press-fitting block 563 is fixedly connected to the piston rod of the press-fitting block telescopic cylinder 562. The press-fitting block 563 is located near the upper intermediate guide post 541. The end face of 41 has a semi-cylindrical groove formed in the middle to mate with the upper intermediate guide post 541. To improve the positional stability of the pair of pressing blocks 563 during pressing, a connecting plug is formed on the end face of one pressing block 563 near the other pressing block 563. There can be two connecting plugs, located on opposite sides of the pressing groove. A connecting slot is formed on the corresponding end face of the other pressing block 563 for the connecting plug to be inserted. When the pair of pressing blocks 563 approach each other, the connecting plug is inserted into the corresponding connecting slot, thus connecting the pair of pressing blocks 563 into one unit, resulting in better positional stability, greater overall strength, and improved pressing performance. In other embodiments, the upper bearing pressing electric cylinder 55 and the pressing block telescopic cylinder 562 can be replaced by other linear drive components.

[0063] During operation, after the bearing 153 slides down along the upper intermediate guide post 541 and leaves the outer support sleeve 542, a pair of press block telescopic cylinders 562 drive a pair of press blocks 563 to move closer to each other. Then, a pair of upper bearing press electric cylinders 55 drive a pair of press block assemblies 56 to descend synchronously, thereby pressing the bearing 153 into the upper end of the worm gear 15.

[0064] refer to Figure 14 The horizontal switching mechanism 7 includes a support base 71, a horizontal switching motor 72 fixed on the support base 71, and a circular plate-shaped switching support platform 73 coaxially fixed to the upper end of the output shaft of the horizontal switching motor 72. A driven gear pressing mechanism 8 and a lower bearing pressing mechanism 9 are disposed on the switching support platform 73, and their central axes are symmetrically arranged relative to the central axis of the switching support platform 73. To increase the active stability of the switching support platform 73, a plurality of auxiliary support rods 74 are fixed on the bottom surface of the switching support platform 73. The number of auxiliary support rods 74 is at least two or more (an even number) to ensure that both the driven gear pressing mechanism 8 and the lower bearing pressing mechanism 9 have auxiliary support rods 74 at their bottoms. Each auxiliary support rod 74 includes a support rod body 741 fixed to the lower end surface of the switching support platform 73 and a support caster wheel 742 fixed to the bottom of the support rod body 741. In other embodiments, the horizontal switching motor 72 can be replaced by other rotary switching drive components.

[0065] refer to Figure 14 The driven gear pressing mechanism 8 includes a driven gear storage seat 82, a driven gear lifting drive assembly 81 for driving the driven gear storage seat 82 to rise and fall vertically, and a driven gear pressing assembly.

[0066] refer to Figure 14 The driven gear storage base 82 includes a driven gear storage base plate 821 and a driven gear storage column 822 fixed on the upper end surface of the driven gear storage base plate 821. The main body of the driven gear storage column 822 is a cylinder and a vertical guide bar is formed on the cylinder to cooperate with the keyway of the driven gear. In this way, a number of vertically stacked driven gears 151 can be sleeved on the driven gear storage column 822 and the rotation of the driven gears 151 can be restricted.

[0067] refer to Figure 14 To reduce the distance between the driven gear storage column 822 and the position on the worm gear 15 where the driven gear 151 is installed, thus ensuring that the driven gear 151 accurately reaches the installation position of the worm gear 15, the upper end of the driven gear storage column 822 is formed with a connecting slot 8220 for the lower end of the worm gear 15 to be inserted. This, in conjunction with the driven gear lifting drive assembly 81, allows the driven gear storage column 822 to detach from or be fitted onto the lower end of the worm gear 15. When pressing the driven gear 151, the driven gear storage column 822 is at its uppermost position, and the connecting slot 8220 is fitted onto the lower end of the worm gear 15. When the worm gear 15 is feeding or discharging, the driven gear storage column 822 is at its lowermost position and separated from the worm gear 15. The driven gear lifting drive assembly 81 includes several driven gear lifting drive electric cylinders, and the driven gear storage base plate 821 is fixed to the upper end of the piston rod of the driven gear lifting drive electric cylinder. In other embodiments, the driven gear lifting drive electric cylinder can be replaced by other linear drive components.

[0068] refer to Figure 14 The driven gear press-fit assembly includes a driven gear press-fit base 85 and a driven gear press-fit drive component for driving the driven gear press-fit base 85 to rise and fall; the driven gear press-fit base 85 is vertically sleeved on the driven gear storage column 822; the driven gear press-fit drive component includes at least one pair of driven gear press-fit drive members; the driven gear press-fit drive member includes a driven gear press-fit drive motor 83 fixed to the bottom surface of the driven gear storage base plate 821 and a driven gear press-fit screw 84 coaxially fixed to the output shaft of the driven gear press-fit drive motor 83; all driven gear press-fit screws 84 vertically pass through the driven gear press-fit base 85 and are threadedly connected to the driven gear press-fit base 85. To improve the rotational stability of the driven gear press-fit screw 84, a pair of first vertical rods are fixed to the upper surface of the driven gear storage base plate 821. A circular first upper support ring 86 is fixed to the upper end of each pair of first vertical rods. The upper surface of the first upper support ring 86 is flush with the upper surface of the driven gear storage column 822. The upper end of the driven gear press-fit screw 84 is rotatably connected to the first upper support ring 86. To reduce the influence of the first upper support ring 86, the driven gear press-fit base 85 includes a driven gear press-fit base plate and a driven gear press-fit protrusion formed on the driven gear press-fit base plate, wherein the height of the driven gear press-fit protrusion is greater than the height of the first upper support ring 86. Thus, the driven gear press-fit assembly drives all the driven gears 151 on the driven gear storage column 822 to rise with equal clearance, thereby press-fitting the uppermost driven gear 151 onto the lower end of the worm gear 15.

[0069] refer to Figure 14 The lower bearing press-fit mechanism 9 includes a lower bearing guide column 91 fixed on the upper end face of the switching support table 73 and a lower bearing press-fit assembly; the lower bearing press-fit assembly includes a lower bearing press-fit seat 94 and a lower bearing press-fit drive component for driving the lower bearing press-fit seat 94 to rise and fall; the lower bearing press-fit seat 94 is vertically sleeved on the lower bearing guide column 91; the lower bearing press-fit drive component includes at least one pair of lower bearing press-fit drive members; the lower bearing press-fit drive member includes a lower bearing press-fit drive motor 92 fixed on the lower end face of the switching support table 73 and a lower bearing press-fit screw 93 coaxially fixed on the output shaft of the lower bearing press-fit drive motor 92; all the lower bearing press-fit screws 93 vertically pass through the lower bearing press-fit seat 94 and are threadedly connected to the lower bearing press-fit seat 94. To improve the rotational stability of the lower bearing press-fit screw 93, a pair of second vertical rods are fixed on the upper end face of the switching support platform 73. A circular second upper support ring 95 is fixed at the upper end of the pair of second vertical rods. The upper end face of the second upper support ring 95 is flush with the upper end face of the driven gear storage column 822. The upper end of the lower bearing press-fit screw 93 is rotatably connected to the second upper support ring 95.

[0070] To reduce the impact of the second upper support ring 95, the lower bearing press-fit seat 94 includes a lower bearing press-fit base plate and a lower bearing press-fit protrusion formed on the lower bearing press-fit base plate, wherein the height of the lower bearing press-fit protrusion is greater than the height of the second upper support ring 95. In this way, the lower bearing press-fit assembly drives all bearings 153 on the lower bearing guide post 91 to rise with equal clearance, thereby press-fitting the uppermost bearing 153 onto the lower end of the worm gear 15.

[0071] Example 3: The difference between Example 3 and Example 2 is as follows: (Refer to...) Figure 9 and Figure 10 A worm gear adjustment device 35 is provided at the loading and unloading point of the worm gear 15. The worm gear adjustment device 35 includes an adjustment seat 352, an adjustment lifting mechanism 351, an adjustment ring seat 353, and a ring seat rotation drive mechanism. The adjustment lifting mechanism 351 is an adjustment lifting electric cylinder or other linear drive component. The adjustment seat 352 is fixed to the upper end of the piston rod of the adjustment lifting electric cylinder. An adjustment slot 3520 for the lower end of the worm gear 15 to be inserted is formed at the center of the upper end surface of the adjustment seat 352. The adjustment ring seat 353 is a cylindrical ring and is rotatably connected to the upper end surface of the adjustment seat 352 through a bearing. The adjustment ring seat 353 and the adjustment slot 3520 are coaxially arranged.

[0072] refer to Figure 10 The inner cylindrical surface of the adjusting ring seat 353 is formed with a telescopic storage groove 3530. An adjusting key block 354, which engages with the keyway of the worm gear 15, is telescopically installed within the telescopic storage groove 3530. A pair of telescopic guide rods 3541 are formed on the end face of the adjusting key block 354 near the telescopic storage groove 3530. A stop block is formed at the end of the telescopic guide rod 3541 that horizontally passes through the side wall of the telescopic storage groove 3530 and is away from the adjusting key block 354. A compression spring 355 is sleeved on the telescopic guide rod 3541. One end of the compression spring 355 abuts against the adjusting key block 354, and the other end… The key block 354 is elastically telescopically positioned within the telescopic storage groove 3530, and a retraction limiting component 356 is provided on the inner wall of the telescopic storage groove 3530 to keep the key block 354 in a retracted state. The retraction limiting component 356 can be an electromagnet, and the key block 354 can be attracted by a magnet. In the initial state, the key block 354 of the adjusting ring seat 353 is directly opposite the pressing direction of the key pressing device 4, and the key block 354 is attracted by the electromagnet and hidden within the telescopic storage groove 3530.

[0073] refer to Figure 10 The ring seat rotation drive mechanism includes a ring seat rotation drive motor 357 fixed on the adjusting seat 352, a ring seat rotation drive gear 358 coaxially fixed on the output shaft of the ring seat rotation drive motor 357, and a ring seat rotation drive gear ring 359 coaxially fixed on the adjusting ring seat 353; the ring seat rotation drive gear ring 359 meshes with the ring seat rotation drive gear 358.

[0074] During operation, the lower end of the worm 15 passes through the adjusting ring seat 353 and is inserted into the adjusting slot 3520. Then, the electromagnet loses its magnetism, and the adjusting key block 354 extends out under the action of the compression spring 355 and abuts against the cylindrical surface where the keyway of the worm 15 is located. Then, the ring seat rotation drive mechanism drives the adjusting ring seat 353 to rotate one revolution. During this process, the adjusting key block 354 will be inserted into the keyway of the worm 15 under the action of the compression spring 355. Thus, when the adjusting ring seat 353 stops rotating and returns to the initial state, the keyway of the worm 15 is aligned with the pressing direction of the key pressing device 4. In this way, when the worm feeding and discharging device 3 grabs the worm 15, the keyway of the worm 15 can still be aligned with the pressing direction of the key pressing device 4, which is beneficial for the subsequent pressing of the key 152.

[0075] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
