Description

Technical Field

[0001] This invention relates to the field of conveying equipment technology, and in particular to a conveying device for a speed reducer end cover. Background Technology

[0002] A speed reducer is an independent component consisting of gear drives, worm drives, or gear-worm drives enclosed in a rigid housing. It is commonly used as a speed reduction transmission device between a prime mover and a working machine. It plays a role in matching speeds and transmitting torque between the prime mover and the working machine or actuator, and is widely used in modern machinery. The speed reducer end cover serves as a positioning and protective element for the speed reducer. During machining, the speed reducer end cover often requires a conveying device for auxiliary movement.

[0003] In existing technologies, conveyor devices for reducer end covers typically use belt conveyors for movement. This makes it difficult to easily load and unload the reducer end covers during processes such as painting and grinding, and prevents them from being rotated without dead angles during transport. This reduces the ease of use and functionality of the conveyor device. Therefore, there is a need to provide a conveyor device for reducer end covers that can solve the problem of the inability to rotate the end covers during transport in existing technologies. Summary of the Invention

[0004] The purpose of this invention is to provide a conveying device for speed reducer end covers, which can solve the problem that speed reducer end covers cannot be rotated during the conveying process in the prior art.

[0005] This invention is implemented as follows:

[0006] A conveying device for a speed reducer end cover includes an adjusting and protective mechanism, a conveying drive mechanism, a clamping and tilting mechanism, and a drive adjusting mechanism. Two sets of conveying drive mechanisms are respectively arranged at the upper and lower parts of the adjusting and protective mechanism, and are arranged along the conveying direction of the speed reducer end cover. The ends of the projections of the two sets of conveying drive mechanisms on the horizontal plane are connected on the same straight line. One end of each set of clamping and tilting mechanisms is a mounting end and is movably mounted on the adjusting and protective mechanism through the two sets of conveying drive mechanisms. The other end of each set of clamping and tilting mechanisms forms a rotatable clamping end through the drive adjusting mechanism. The clamping directions of the rotatable clamping ends of the two sets of clamping and tilting mechanisms are perpendicular, so that each set of clamping and tilting mechanisms can clamp the speed reducer end cover through the rotatable clamping end, and the speed reducer end cover is transferred between the rotatable clamping ends of the two sets of clamping and tilting mechanisms.

[0007] The adjustment and protection mechanism includes a first adjustment frame, a lifting assembly, and a second adjustment frame.

[0010] The first drive assembly includes a first positioning screw and a third motor; the third motor is mounted on the outer wall of the fixed frame, the first positioning screw is rotatably disposed in the hollow cavity of the fixed frame, and one end of the first positioning screw passes through the fixed frame and is coaxially fixed to the output shaft of the third motor; one end of the adjusting seat has a screw hole that matches the first positioning screw, so that one end of the adjusting seat can be slidably embedded in the fixed frame, and the other end of the adjusting seat passes through the opening of the fixed frame and is connected to the clamping and flipping mechanism.

[0011] Each clamping and flipping mechanism includes a positioning frame, a movable seat, a second drive assembly, a limiting guide assembly, a connecting rod, a positioning seat, and a rotating seat. The positioning frame is fixedly installed on the other end of the adjusting seat, and the second drive assembly is connected between the adjusting seat and the positioning frame. A pair of limiting guide assemblies are respectively disposed at both ends inside the positioning frame and connected to both ends of the second drive assembly. A pair of movable seats are movably disposed on the positioning frame through a pair of limiting guide assemblies. A pair of positioning seats are respectively connected to a pair of movable seats through a pair of connecting rods. A pair of rotating seats are rotatably disposed on a pair of positioning seats through a pair of drive adjustment mechanisms, and the pair of rotating seats are arranged opposite to each other and can clamp the reducer end cover.

[0012] Anti-slip pads are provided on the opposite sides of a pair of rotating seats, and the pair of rotating seats are clamped to the end cover of the reducer by the anti-slip pads.

[0013] The second drive assembly includes a positioning gear, a positioning rack, and a first motor; a recess is formed at the other end of the adjusting seat so that the first motor is embedded in the recess; the positioning gear is rotatably mounted in the middle of the positioning frame, and a pair of positioning racks are slidably attached to the inner walls of both sides of the positioning frame and mesh with the two ends of the positioning gear for transmission; the output shaft of the first motor passes through the positioning frame and is coaxially fixed to the positioning gear; the ends of the pair of positioning racks are respectively connected to a pair of limiting guide assemblies.

[0014] Each set of limiting and guiding components includes a positioning groove and a movable frame; the positioning groove is formed on the positioning frame and is located parallel between a pair of positioning racks; the movable frame has an I-shaped structure, and the middle part of the movable frame passes through the positioning groove through the positioning frame, so that one end of the movable frame is slidably set inside the positioning frame and fixedly connected to the end of the positioning rack, and the other end of the movable frame is slidably set outside the positioning frame and fixedly connected to the movable seat.

[0016] The third drive assembly includes a second motor, a fixed base, a positioning shaft, and positioning strips. The fixed base has a ring structure, with its outer ring rotatably fitted into a movable base. The inner ring of the fixed base forms several positioning grooves. Several positioning strips are spaced apart on the surface of the positioning shaft, and these strips can be matched to pass through the positioning grooves, allowing the positioning shaft to slide through the inner ring of the fixed base.

[0018] Compared with the prior art, the present invention has the following advantages:

[0019] 1. This invention, by incorporating an adjustment and protection mechanism, a conveying and driving mechanism, a clamping and flipping mechanism, and a driving and adjusting mechanism, allows the reducer end cover to be transferred between two sets of clamping and flipping mechanisms. These two sets of clamping and flipping mechanisms clamp the reducer end cover in different directions and drive it to rotate via the driving and adjusting mechanism. This facilitates the omnidirectional flipping and rotation of the reducer end cover while it is being conveyed along the two sets of conveying and driving mechanisms, solving the problem of the inability to flip the reducer end cover during conveying in the prior art. This also facilitates omnidirectional painting, grinding, and other processing of the reducer end cover, improving processing efficiency and quality.

[0020] 2. Because the present invention is equipped with an adjustment and protection mechanism, two sets of clamping and flipping mechanisms are located at the upper and lower parts of the adjustment and protection mechanism. The clamping end height of the lower clamping and flipping mechanism can be adjusted to avoid obstacles when transporting the reducer end cover. It also makes it easy to adjust the two pairs of rotating seats to the same horizontal height so that the two pairs of rotating seats clamp the reducer end cover from the front, back, left and right. This ensures the stability and safety of the reducer end cover when it is transferred between the two sets of clamping and flipping mechanisms. After the transfer, the clamping and flipping mechanism of the reducer end cover can be reversed and the driving adjustment mechanism can be reversed.

[0021] 3. This invention achieves clamping, conveying, transferring and unloading of reducer end caps through motor control. It has a simple structure, high ease of operation, and low cost. It can be applied to various processing lines for reducer end caps and can be combined with different processing operations. It has good adaptability and prospects for widespread application.

[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0031] Please see the appendix Figure 1 and attached Figure 2 A conveying device for a speed reducer end cover includes an adjusting and protective mechanism 1, a conveying drive mechanism 2, a clamping and flipping mechanism 3, and a drive adjusting mechanism 4. Two sets of conveying drive mechanisms 2 are respectively arranged at the upper and lower parts of the adjusting and protective mechanism 1, and are arranged along the conveying direction of the speed reducer end cover. The ends of the projections of the two sets of conveying drive mechanisms 2 on the horizontal plane are connected on the same straight line. One end of each set of clamping and flipping mechanisms 3 is a mounting end and is movably mounted on the adjusting and protective mechanism 1 through the two sets of conveying drive mechanisms 2. The other end of each set of clamping and flipping mechanisms 3 forms a rotatable clamping end through the drive adjusting mechanism 4. The clamping direction of the rotatable clamping ends of the two sets of clamping and flipping mechanisms 3 is perpendicular, so that each set of clamping and flipping mechanisms 3 can clamp the speed reducer end cover through the rotatable clamping end, and the speed reducer end cover is transferred between the rotatable clamping ends of the two sets of clamping and flipping mechanisms 3.

[0032] The conveying device of the present invention can be installed on the side of the painting, grinding and other processing production line of the reducer end cover. The two sets of conveying drive mechanisms 2 can be used to convey the reducer end cover. The conveying path is relatively long, which makes it convenient to carry out painting, grinding and other processing while conveying the reducer end cover.

[0033] By setting two sets of clamping and flipping mechanisms 3 in different directions, not only can the stable clamping of the reducer end cover be ensured during transportation, but the two sets of clamping and flipping mechanisms 3 can also clamp the reducer end cover in different directions and realize the transportation and transfer between the two sets of transportation drive mechanisms 2. After the transfer, the reducer end cover turns, that is, the reducer end cover is transported in different directions on the two sets of transportation drive mechanisms 2, so that different positions of the reducer end cover can be better processed such as painting and grinding.

[0034] Preferably, the two clamping ends of the clamping and flipping mechanism 3 located at the upper part of the adjusting and protective mechanism 1 are arranged downwards, and the two clamping ends of the clamping and flipping mechanism 3 located at the lower part of the adjusting and protective mechanism 1 are arranged upwards. This ensures that the four clamping ends are located in the same horizontal plane and clamp the reducer end cover in the front, back, left, and right directions, guaranteeing that the reducer end cover will not fall off when transferred between the two sets of clamping and flipping mechanisms 3. At the same time, the ends of the projections of the two sets of conveying drive mechanisms 2 on the horizontal plane are connected to the same straight line, that is, the projections of the two sets of conveying drive mechanisms 2 on the horizontal plane have overlapping conveying trajectories, ensuring that the two sets of clamping and flipping mechanisms 3 can clamp the reducer end cover simultaneously, thereby ensuring the safe transfer of the reducer end cover.

[0035] By setting the drive adjustment mechanism 4, the clamping end of the clamping and flipping mechanism 3 can be driven to rotate, thereby enabling the clamping and flipping mechanism 3 to stably clamp the reducer end cover and drive the reducer end cover to rotate. Since the clamping directions of the two sets of clamping and flipping mechanisms 3 are different, the flipping direction of the reducer end cover is also different by driving the adjustment mechanism 4, thereby realizing the all-round flipping of the reducer end cover, which is convenient for painting, grinding and other processing, and improves processing efficiency and processing quality.

[0036] Please see the appendix Figure 3 The adjustment and protection mechanism 1 includes a first adjustment frame 101, a lifting assembly, and a second adjustment frame 104. The first adjustment frame 101 has a C-shaped structure, wherein a set of conveying drive mechanisms 2 are installed on the top crossbar of the first adjustment frame 101, and the second adjustment frame 104 is installed on the bottom crossbar of the first adjustment frame 101 via the lifting assembly. Another set of conveying drive mechanisms 2 is installed on the second adjustment frame 104.

[0037] Preferably, the first adjusting frame 101 and the second adjusting frame 104 can be made of square steel tubes. The lifting component is used to control the second adjusting frame 104 to rise or fall, thereby controlling the height adjustment of the conveying drive mechanism 2, the clamping and flipping mechanism 3 and the speed reducer end cover mounted on it. It can effectively avoid obstacles and ensure that the clamping ends of the two clamping and flipping mechanisms 3 can stably and effectively clamp the speed reducer end cover when transferring the speed reducer end cover between the two sets of clamping and flipping mechanisms 3.

[0038] Please see the appendix Figure 3The lifting assembly includes a second positioning screw 102, a fourth motor 103, and a fixing rod 105. The fourth motor 103 is fixedly mounted on the vertical rod of the first adjusting frame 101 via a mounting plate. One end of the second positioning screw 102 passes through the mounting plate and is coaxially fixed to the output shaft of the fourth motor 103. The other end of the second positioning screw 102 is rotatably mounted on the bottom crossbar of the first adjusting frame 101 via a rotating bearing seat. One end of the second adjusting frame 104 has a screw hole that matches the second positioning screw 102, so that one end of the second adjusting frame 104 is vertically connected to the second positioning screw 102 via threaded transmission. The other end of the second adjusting frame 104 is fixedly connected to another set of conveying drive mechanisms 2. A sliding hole (not shown in the figure) is formed on the second adjusting frame 104. The fixing rod 105 is vertically fixed on the bottom crossbar of the first adjusting frame 101 and slides through the sliding hole through the second adjusting frame 104.

[0039] Preferably, the fourth motor 103 can be a small motor with bidirectional rotation function in the prior art, used to drive the second positioning screw 102 to rotate in the forward or reverse direction. The second positioning screw 102 and the fixing rod 105 are arranged vertically and parallel to each other.

[0040] When the second positioning screw 102 rotates in the forward direction, the second adjusting frame 104 is driven by a thread. Since the second adjusting frame 104 is restricted by the fixed rod 105, it cannot rotate with the second positioning screw 102. Therefore, the rotation of the second positioning screw 102 is converted into a linear upward movement of the second adjusting frame 104 along the axial direction of the second positioning screw 102, thus achieving the upward function of the second adjusting frame 104. Similarly, when the second positioning screw 102 rotates in the reverse direction, the second adjusting frame 104 can be lowered; the reverse movement process will not be described in detail here.

[0041] Please see the appendix Figure 7 Each set of conveying drive mechanisms 2 includes a fixed frame 201, a first drive assembly, and an adjusting seat 204; the fixed frame 201 of one set of conveying drive mechanisms 2 is installed on the top crossbar of the first adjusting frame 101, and the fixed frame 201 is a hollow frame with an open bottom; the fixed frame 201 of the other set of conveying drive mechanisms 2 is installed on the other end of the second adjusting frame 104, and the fixed frame 201 is a hollow frame with an open top; the adjusting seat 204 is slidably embedded in the fixed frame 201 through the first drive assembly, and the clamping and flipping mechanism 3 is installed on the adjusting seat 204.

[0042] Driven by the first drive assembly, the adjusting seat 204 slides along the hollow cavity of the fixed frame 201, and drives the clamping and flipping mechanism 3 to slide synchronously, thereby realizing the sliding conveying of the reducer end cover clamped by the clamping and flipping mechanism 3. The fixed frame 201 can be a long, straight, hollow frame made of metal, and the length of the fixed frame 201 can be adapted to the conveying distance.

[0043] Please see the appendix Figure 7 The first driving assembly includes a first positioning lead screw 202 and a third motor 203. The third motor 203 is mounted on the outer wall of the fixed frame 201. The first positioning lead screw 202 is rotatably disposed in the hollow cavity of the fixed frame 201 through a rotating bearing seat. One end of the first positioning lead screw 202 passes through the fixed frame 201 and is coaxially fixed to the output shaft of the third motor 203. One end of the adjusting seat 204 has a screw hole that matches the first positioning lead screw 202, so that one end of the adjusting seat 204 is slidably embedded in the fixed frame 201 through threaded transmission. The other end of the adjusting seat 204 passes through the opening of the fixed frame 201 and is connected to the clamping and flipping mechanism 3.

[0044] Preferably, the third motor 203 can be a small motor with bidirectional rotation function in the prior art, used to drive the first positioning screw 202 to rotate in the forward or reverse direction.

[0045] When the first positioning screw 202 rotates in the forward direction, the threaded transmission adjustment seat 204 is used. The two sides of the adjustment seat 204 slide against the inner walls of the hollow cavity on both sides of the fixed frame 201, which restricts the rotation of the adjustment seat 204. This converts the rotation of the first positioning screw 202 into linear movement of the adjustment seat 204 along the axial direction of the first positioning screw 202, thereby realizing the linear transport of the clamping and flipping mechanism 3 and the speed reducer end cover it clamps.

[0046] After the two sets of clamping and flipping mechanisms 3 complete the transfer of the reducer end cover, the first positioning screw 202 rotates in the opposite direction, driving the lower clamping and flipping mechanism 3 to move and reset, so as to clamp and transfer the next reducer end cover. The first positioning screw 202 is driven to rotate in the opposite direction by the third motor 203, and its reverse movement process will not be described in detail here.

[0047] Please see the appendix Figure 4 To be continued Figure 6Each clamping and flipping mechanism 3 includes a positioning frame 301, a movable seat 302, a second drive assembly, a limiting guide assembly, a connecting rod 307, a positioning seat 308, and a rotating seat 309. The positioning frame 301 is fixedly installed on the other end of the adjusting seat 204, and the second drive assembly is connected between the adjusting seat 204 and the positioning frame 301. A pair of limiting guide assemblies are respectively disposed at both ends inside the positioning frame 301 and connected to both ends of the second drive assembly. A pair of movable seats 302 are respectively movably disposed on the positioning frame 301 through a pair of limiting guide assemblies. A pair of positioning seats 308 are respectively connected to a pair of movable seats 302 through a pair of connecting rods 307. A pair of rotating seats 309 are respectively rotatably disposed on a pair of positioning seats 308 through a pair of drive adjustment mechanisms 4, and the pair of rotating seats 309 are arranged opposite each other and can clamp the reducer end cover.

[0048] The second drive assembly drives a pair of limit guide assemblies to move a pair of movable seats 302 closer together or further apart. When the movable seats 302 move closer together, they simultaneously move a pair of connecting rods 307, positioning seats 308, and rotating seats 309 closer together. The pair of rotating seats 309 serve as rotatable clamping ends of the clamping and flipping mechanism 3, stably and reliably clamping the reducer end cover and adapting to reducer end covers of different specifications. Conversely, when the movable seats 302 move further apart, the pair of rotating seats 309 release the reducer end cover, facilitating the transfer of the reducer end cover between the two sets of clamping and flipping mechanisms 3 and the unloading of the reducer end cover after it has been transferred to the correct position.

[0049] The length of the connecting rod 307 can be adjusted according to the size of the reducer end cover to prevent the reducer end cover from colliding with the top of the drive adjustment mechanism 4 after a pair of rotating seats 309 clamp the reducer end cover.

[0050] Please see the appendix Figure 4 and attached Figure 7 The second drive assembly includes a positioning gear 303, a positioning rack 304, and a first motor 311; the other end of the adjusting seat 204 has a recess (not shown in the figure) so that the first motor 311 is embedded in the recess; the positioning gear 303 is rotatably mounted in the middle of the positioning frame 301 via a wheel axle, and a pair of positioning racks 304 are respectively slidably attached to the inner walls of both sides of the positioning frame 301 and mesh with the two ends of the positioning gear 303 for transmission; the output shaft of the first motor 311 passes through the positioning frame 301 and is coaxially fixed to the positioning gear 303; the ends of the pair of positioning racks 304 are respectively connected to a pair of limiting guide assemblies.

[0051] Preferably, the first motor 311 can be a small motor with bidirectional rotation function in the prior art, used to drive the positioning gear 303 to rotate in the forward or reverse direction.

[0052] When the positioning gear 303 rotates in the forward direction, it simultaneously meshes with a pair of positioning racks 304 at both ends, causing the pair of positioning racks 304 to move in opposite directions. The pair of positioning racks 304 pulls a pair of limiting guide components closer together, and the pair of limiting guide components drives a pair of moving seats 302 closer together. Conversely, when the positioning gear 303 rotates in the reverse direction, the pair of positioning racks 304 pushes the pair of limiting guide components away from each other, and the pair of moving seats 302 away from each other.

[0053] Please see the appendix Figure 5 Each set of limiting and guiding components includes a positioning groove 305 and a movable frame 306; the positioning groove 305 is formed on the positioning frame 301 and is located parallel between a pair of positioning racks 304; the movable frame 306 has an I-shaped structure, and the middle part of the movable frame 306 passes through the positioning frame 301 through the positioning groove 305, so that one end of the movable frame 306 is slidably set inside the positioning frame 301 and fixedly connected to the end of the positioning rack 304, and the other end of the movable frame 306 is slidably set outside the positioning frame 301 and fixedly connected to the movable seat 302.

[0054] The positioning groove 305 is used to install the movable frame 306 and to guide and limit the sliding of the movable frame 306, so that it can make linear reciprocating motion, thereby realizing the mutual approach or movement of a pair of movable seats 302, with high motion stability.

[0055] Please see the appendix Figure 5 Each of the drive adjustment mechanisms 4 includes a third drive component, a limiting seat 402, and a transmission component. The third drive component is installed at the end of the positioning frame 301 through the limiting seat 402. One end of the transmission component is connected to the third drive component, and the other end of the transmission component is located on a surface of the positioning seat 308 away from the rotating seat 309. The other end of the transmission component passes through the positioning seat 308 and is connected to the rotating seat 309.

[0056] The third drive assembly is used to drive the transmission assembly to move, so that the transmission assembly can drive a pair of rotating seats 309 to rotate synchronously, thereby realizing the rotation of the reducer end cover between the pair of rotating seats 309, which is beneficial for all-round painting, grinding and other processing of the reducer end cover.

[0057] A pair of limit seats 402 are installed at both ends of the positioning frame 301 to facilitate the installation of the drive adjustment mechanism 4 onto the positioning frame 301.

[0058] Please see the appendix Figure 4 To be continued Figure 6The third drive assembly includes a second motor 401, a fixed base 403, a positioning shaft 404, and positioning strips 405. The fixed base 403 has a ring structure, and its outer ring is rotatably embedded in the movable base 302. The inner ring of the fixed base 403 has several positioning grooves (not shown in the figure). Several positioning strips 405 are respectively spaced on the surface of the positioning shaft 404, and the several positioning strips 405 can match and pass through the several positioning grooves, so that the positioning shaft 404 slides through the inner ring of the fixed base 403. The second motor 401 is mounted on the limiting base 402, and the output shaft of the second motor 401 passes through the limiting base 402 and is coaxially fixed to the end of the positioning shaft 404. The transmission assembly is sleeved on the positioning shaft 404.

[0059] Preferably, the second motor 401 can be a small motor with bidirectional rotation function in the prior art, used to drive the positioning shaft 404 to rotate in the forward or reverse direction, thereby providing forward or reverse driving force to the transmission component through the positioning shaft 404.

[0060] The fixed seat 403 is used for mounting the positioning shaft 404 between a pair of movable seats 302. The fixed seat 403 can be a rotary bearing, allowing the positioning shaft 404 to rotate relative to the pair of movable seats 302, thus avoiding affecting the linear movement of the pair of movable seats 302. The relative sliding between several positioning grooves and several positioning strips 405 serves as a guide and limiter, ensuring the linear movement of the pair of movable seats 302 along the positioning shaft 404, thereby ensuring that the pair of movable seats 302 can move closer to or further away from each other.

[0061] Please see the appendix Figure 6 The transmission assembly includes a first helical gear 406, a second helical gear 407, a fixed shaft 408, a mounting base 409, a third helical gear 410, and a fourth helical gear 411. The first helical gear 406 is coaxially sleeved on the positioning shaft 404. The two ends of the fixed shaft 408 are rotatably mounted on the connecting rod 307 via a pair of mounting bases 409 and rotating bearings, so that the fixed shaft 408 is parallel to the outside of the connecting rod 307. The second helical gear 407 is coaxially sleeved on one end of the fixed shaft 408 and meshes with the first helical gear 406 for transmission. The third helical gear 410 is coaxially sleeved on the other end of the fixed shaft 408. The fourth helical gear 411 is rotatably mounted on a surface of the positioning base 308 away from the rotating base 309 via a wheel axle and meshes with the third helical gear 410 for transmission. The fourth helical gear 411 and the rotating base 309 are coaxially fixedly connected via a wheel axle.

[0062] The first helical gear 406 rotates synchronously with the positioning shaft 404 in either the forward or reverse direction. When the first helical gear 406 rotates in the forward direction, it first meshes with the second helical gear 407, causing the second helical gear 407 to drive the fixed shaft 408 to rotate in the forward direction between a pair of mounting seats 409. Then, the fixed shaft 408 drives the third helical gear 410 to rotate synchronously in the forward direction. The third helical gear 410 meshes with the fourth helical gear 411, and finally, the fourth helical gear 411 drives the rotating seat 309 to rotate synchronously in the forward direction via the wheel and axle. Conversely, the reverse rotation of the positioning shaft 404 can drive the rotating seat 309 to rotate synchronously in the reverse direction. The reverse motion process will not be described in detail here.

[0063] Preferably, a pair of transmission components can share a set of third drive components, or a pair of transmission components can be synchronously driven by a pair of synchronously moving third drive components, thereby realizing synchronous forward rotation or synchronous reverse rotation of a pair of rotating seats 309, thereby realizing the omnidirectional flipping rotation of the reducer end cover driven by a pair of rotating seats 309 in the forward or reverse direction.

[0064] Please see the appendix Figure 6 The pair of rotating seats 309 are provided with anti-slip pads 310 on their opposite sides, and the pair of rotating seats 309 are clamped on the reducer end cover by the anti-slip pads 310.

[0065] Preferably, the anti-slip pad 310 can be made of a material with good anti-slip effect, such as rubber, to ensure the clamping stability of the reducer end cover.

[0066] Please see the appendix Figure 1 To be continued Figure 7 The working process and working principle of this invention are as follows:

[0067] In the initial state, the adjustment seat 204 at the lower part of the first adjustment frame 101 is located at the end of the first positioning screw 202 away from the upper part of the first adjustment frame 101, away from the conveying drive mechanism 2. The reducer end cover is first clamped by the clamping and flipping mechanism 3 at the lower part of the first adjustment frame 101. The clamping method is as follows:

[0068] Start the first motor 311, which drives the positioning gear 303 to rotate in the forward direction. The positioning gear 303 meshes with and drives a pair of positioning racks 304. The pair of positioning racks 304 drive a pair of moving frames 306 to slide along a pair of positioning grooves 305 and move closer to each other. This causes the pair of moving frames 306 to drive a pair of moving seats 302, a pair of connecting rods 307, a pair of positioning seats 308 and a pair of rotating seats 309 to move closer together synchronously. In turn, the pair of rotating seats 309 clamp the reducer end cover through the anti-slip pad 310.

[0069] During the movement of the movable seat 302, the fixed seat 403 moves synchronously with the movable seat 302. The positioning groove of the inner ring of the fixed seat 403 slides relative to the positioning strip 405 to ensure that the movable seat 302 moves in a straight line along the positioning shaft 404 and the positioning groove 305 arranged in parallel with each other, thereby ensuring that the close clamping action of a pair of rotating seats 309 is stable and controllable.

[0070] The reducer end cover is conveyed by the conveying drive mechanism 2 at the lower part of the first adjusting frame 101 to the conveying drive mechanism 2 at the upper part of the first adjusting frame 101. During the conveying process, the reducer end cover can be painted, polished, etc., and the reducer end cover can be rotated by the drive adjusting mechanism 4 to ensure uniform painting and polishing.

[0071] The conveying method of the conveying drive mechanism 2 is as follows: the third motor 203 is started, and the third motor 203 drives the first positioning screw 202 to rotate in the forward direction. The screw drive causes the adjusting seat 204 to slide in the fixed frame 201 along the axial direction of the first positioning screw 202. This causes the adjusting seat 204 to drive the clamping and flipping mechanism 3 and the speed reducer end cover it clamps to move from one end of the first positioning screw 202 to the other end, that is, to convey the speed reducer end cover to the conveying drive mechanism 2 on the upper part of the first adjusting frame 101.

[0072] The method for driving the adjustment mechanism 4 to rotate the reducer end cover is as follows: The second motor 401 is started, which drives the positioning shaft 404 to rotate in the forward direction. The positioning shaft 404 rotates relative to the moving seat 302 through the outer ring of the fixed seat 403, without causing the moving seat 302 to rotate, thus ensuring that the moving seat 302 only performs linear motion. Simultaneously, the positioning shaft 404 drives the first helical gear 406 to rotate synchronously, causing the first helical gear 406 to mesh with and transmit the second helical gear 407. The second helical gear 407 then drives the fixed shaft 408 and its third helical gear 410 to rotate synchronously, causing the third helical gear 410 to mesh with and transmit the fourth helical gear 411. The rotation of the fourth helical gear 411 simultaneously drives the rotating seat 309 to rotate synchronously.

[0073] The two sets of transmission components can share a third drive component, so that the second motor 401 can simultaneously drive a pair of rotating seats 309 to rotate synchronously, thereby enabling the pair of rotating seats 309 to drive the reducer end cover to rotate stably.

[0074] When the reducer end cover is conveyed to the conveying drive mechanism 2 on the upper part of the first adjusting frame 101, a pair of rotating seats 309 of the clamping and flipping mechanism 3 on the upper part of the first adjusting frame 101 are clamped on the reducer end cover. The clamping method is the same as the clamping method of the clamping and flipping mechanism 3 on the lower part of the first adjusting frame 101, only the clamping position and clamping direction are different, which will not be described in detail here.

[0075] The reducer end cover continues to be transmitted through the conveying drive mechanism 2 on the upper part of the first adjusting frame 101, so that the reducer end cover moves from one end of the first positioning screw 202 on the upper part of the first adjusting frame 101 to the other end. During the movement, the reducer end cover can be further processed by painting, grinding and other operations. The reducer end cover can also be flipped by the drive adjusting mechanism 4 during the movement.

[0076] Because the clamping directions of the two sets of clamping and flipping mechanisms 3 at the upper and lower parts of the first adjusting frame 101 are perpendicular, and the drive adjusting mechanism 4 can flip the reducer end cover, the reducer end cover can have a large and flexible flipping range, which can greatly improve the processing quality of the clamping and flipping mechanism 3 for painting, grinding, etc. The rotation method of the drive adjusting mechanism 4 at the upper part of the first adjusting frame 101 is the same as the rotation method of the drive adjusting mechanism 4 at the lower part of the first adjusting frame 101, and will not be described again here.

[0077] When the reducer end cover is transferred between a pair of rotating seats 309 of the two sets of clamping and tilting mechanisms 3, the two pairs of rotating seats 309 can be adjusted to be in the same horizontal plane by adjusting the protective mechanism 1, thereby facilitating the transfer of the reducer end cover between the two sets of clamping and tilting mechanisms 3. The adjustment method of the protective mechanism 1 is as follows:

[0078] The fourth motor 103 is started, which drives the second positioning screw 102 to rotate in the forward direction. Under the transmission of the screw and the limiting action of the fixing rod 105, the second adjusting frame 104 moves linearly up and down along the second positioning screw 102 and the fixing rod 105, thereby adjusting the height of the pair of rotating seats 309 at the lower part of the first adjusting frame 101 so that they are consistent with the height of the pair of rotating seats 309 at the upper part.

[0079] After the two sets of clamping and flipping mechanisms 3 complete the transfer of the reducer end cover, the conveying drive mechanism 2 at the bottom of the adjusting protection mechanism 1 drives the lower clamping and flipping mechanism 3 and the drive adjusting mechanism 4 to move in the opposite direction to reset. The reset process is the reverse movement of the transmission process, and its movement method is the same, only the movement direction is different, which will not be described in detail here.

[0080] Preferably, the switches of the first motor 311, the second motor 401 and the third motor 203 can be set on the first adjustment frame 101 by wires, or a control panel can be installed on the first adjustment frame 101 to integrate the switches of the first motor 311, the second motor 401 and the third motor 203, so as to facilitate centralized control by the operator.

[0081] Similarly, the reducer end cover can also be transmitted from the upper conveying drive mechanism 2 to the lower conveying drive mechanism 2. The transmission direction is not limited and can be adapted to the actual conveying requirements.

[0082] The above are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the invention. Therefore, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
