Description

Technical Field

[0001] This invention relates to the field of automotive assembly technology, and in particular to a shaft system mounting device and a shaft system mounting method. Background Technology

[0002] A car transmission is a gearbox that coordinates the engine speed and the actual speed of the wheels. During vehicle operation, the transmission can create different gear ratios between the engine and wheels, allowing the engine to operate at its optimal power performance through gear shifting. During transmission assembly, the shaft assembly needs to be installed into the transmission housing, a process known as shaft installation. Because manual installation is inefficient and poses certain safety risks, specialized installation equipment is currently used for most shaft installation operations.

[0003] For example, Chinese patent application CN114952913A discloses a gearbox shaft system loading gripper and assembly equipment. The base plate has several shaft system positioning holes. U-shaped clamping blocks are slidably connected to the base plate and located at both ends of the shaft system to be clamped. Hooks are rotatably connected to the base plate and located at both ends of the shaft system parts to be clamped. A lifting device is located below the base plate and is used to lift the shaft system parts after they are installed in the gearbox, facilitating the removal of the grippers. This device achieves the positioning, clamping, and loading of the shaft system parts through the cooperation of various components. Although this patent application can achieve mechanized shaft system loading, there is still much room for improvement in loading efficiency, and it is prone to collisions, which can damage the shaft system assembly.

[0004] Therefore, how to improve the safety of shaft system installation while ensuring the efficiency of shaft system installation is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] The primary objective of this invention is to provide a shaft loading device that can improve the safety of shaft loading while ensuring loading efficiency.

[0006] The second objective of this invention is to provide a shaft system loading method that employs the aforementioned shaft system loading equipment, which offers high loading efficiency and high operational safety.

[0007] To achieve the aforementioned primary objective, the present invention provides the following technical solution: A shaft system housing installation device is provided, comprising: A clamping device includes a first support plate, a second support plate, a floating mechanism, a locking mechanism, and a clamping mechanism. The first support plate is connected to the second support plate through the floating mechanism. The second support plate is movable relative to the first support plate.

[0009] Specifically, in the clamping device, the clamping mechanism is used to clamp each shaft core in the shaft assembly. The transport device transports the clamping device to the top of the housing, and then drives the clamping device to move downward to drive the shaft assembly into the housing. During the transport process, due to the floating mechanism, the second support plate can move up and down and horizontally relative to the first support plate. If the clamping device accidentally deviates slightly during the descent and accidentally hits the inner wall of the housing, the second support plate will move on its own to compensate for the deviation, instead of moving directly downward, thus avoiding prolonged rigid contact with the inner wall of the housing, preventing damage to the housing, and improving the safety of the shaft assembly entering the housing.

The floating column is provided with a second limiting step, which abuts against the upper end of the second positioning sleeve. Both ends of the floating column are provided with floating limiting members to restrict the floating column from detaching from the first positioning sleeve and the second positioning sleeve. The two ends of the floating spring apply elastic force to the first support plate and the second support plate, respectively.

[0011] Optionally, the floating mechanism further includes a first thrust ball bearing and a second thrust ball bearing, both of which are located inside the second positioning sleeve and on the upper and lower sides of the second fixed seat, respectively.

[0013] Optionally, the locking mechanism includes a locking support, a locking cylinder, a locking floating joint, and a locking post. The second support plate is provided with a locking hole. The locking support is connected to the first support plate and located on the lower side of the first support plate. The locking cylinder is disposed on the locking support and is connected to the locking post through the locking floating joint to drive the locking post to extend into or out of the locking hole.

[0014] Optionally, the clamping mechanism includes a clamping displacement cylinder, a clamping support plate, and multiple shaft clamping assemblies. The second support plate has a clamping clearance hole in the middle.

The clamping detection seat is disposed on the second support plate and located on the lower side of the second support plate, and the clamping detection element is disposed on the clamping detection seat to detect whether the shaft clamping assembly is holding the corresponding shaft.

[0017] Optionally, the clamping device further includes a pressure detection mechanism, which includes a pressure detection seat, a pressure detection sleeve, a pressure detection pin, a pressure detection spring, and a pressure sensor. The pressure detection seat is disposed on the second support plate and located below the second support plate. The pressure detection sleeve is disposed on the pressure detection seat and extends downward. The pressure sensor is disposed inside the pressure detection sleeve.

[0020] Specifically, in the clamping device, the clamping mechanism is used to clamp each shaft core in the shaft assembly. The transport device transports the clamping device to the top of the housing, and then drives the clamping device to move downward to drive the shaft assembly into the housing. During the transport process, due to the floating mechanism, the second support plate can move up and down and horizontally relative to the first support plate. If the clamping device accidentally deviates slightly during the descent and accidentally hits the inner wall of the housing, the second support plate will move on its own to compensate for the deviation, instead of moving directly downward, thus avoiding prolonged rigid contact with the inner wall of the housing, preventing damage to the housing, and improving the safety of the shaft assembly entering the housing.

[0025] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0026] like Figures 1 to 8 As shown, the present invention provides a shaft system loading device, including a clamping device 1, a first conveying device 2, a second conveying device 3, an assembly device 4, a fixture storage device 5, and a handling device 6.

[0027] For ease of explanation, in this embodiment, each orientation is as follows: Figure 2 As shown.

[0028] In some embodiments, the shaft system loading device further includes an industrial computer, which is electrically connected to the clamping device 1, the first conveying device 2, the second conveying device 3, the assembly device 4, the fixture storage device 5, and the handling device 6, respectively, thus achieving a higher degree of automation.

[0029] Specifically, the industrial control computer used is a commonly used industrial control computer. This invention does not involve the modification of the industrial control computer, so the internal structure of the industrial control computer will not be described in detail.

[0030] Furthermore, the first conveying device 2 is used to convey the shaft cores. The first conveying device 2 includes a first conveyor belt and a first conveying tray. Multiple shaft cores are placed on the first conveying tray. The first conveyor belt conveys the first conveying tray to the first work station, which is the work station when the handling device 6 handles the shaft cores.

[0031] Furthermore, the second conveying device 3 is used to convey the box. The second conveying device 3 includes a second conveyor belt and a second conveying pallet. The box is placed on the second conveying pallet. The second conveyor belt conveys the second conveying pallet to the second work station, which is the work station where the handling device 6 performs the shaft system box insertion operation.

[0032] In some embodiments, the assembly device 4 is used to assemble multiple shaft cores into a shaft system assembly. The assembly device 4 for assembling multiple shaft cores into a shaft core assembly is a conventional device in the art. The present invention does not involve the modification of shaft core assembly, so it will not be described in detail.

[0033] In some embodiments, such as Figures 2 to 8 As shown, the clamping device 1 includes a first support plate 11, a second support plate 12, a floating mechanism 13, a locking mechanism 14, and a clamping mechanism 15. The first support plate 11 is connected to the second support plate 12 through the floating mechanism 13. The second support plate 12 can move relative to the first support plate 11. The clamping mechanism 15 is disposed on the second support plate 12, and the locking mechanism 14 is disposed on the first support plate 11. The locking mechanism 14 is used to restrict the movement of the second support plate 12.

[0034] Specifically, such as Figure 2 and Figure 3 As shown, the first support plate 11 is located above the second support plate 12. The upper end of the floating mechanism 13 is connected to the first support plate 11, and the lower end of the floating mechanism 13 is connected to the second support plate 12. The second support plate 12 can move up and down and horizontally relative to the first support plate 11, while the locking mechanism 14 is used to restrict the movement of the second support plate 12.

[0035] In some embodiments, the clamp storage device 5 is used to store multiple clamping devices 1. It is understood that the shaft core assemblies of different gearboxes are different, and the clamping mechanisms 15 used to clamp the shaft core assemblies are also different. That is, the arrangement and number of different clamping mechanisms 15 are different. Therefore, multiple clamping devices 1 are stored on the clamp storage device 5, and the arrangement and number of clamping mechanisms 15 in each clamping device 1 are different. Different clamping devices 1 can be replaced according to different gearboxes.

[0036] In some embodiments, the handling device 6 is used to handle the shaft core to the assembly device 4 and to handle the shaft assembly to the second conveying device 3 for shaft loading into the housing.

[0037] In some embodiments, the handling device 6 is a robotic arm, and the gripping end of the robotic arm is provided with a quick-change disc 61. In the clamping device 1, a quick-change disc 61 is also provided above the first support plate 11. The robotic arm can grasp the clamping device 1 more quickly, and can also automatically change different clamping devices 1 more quickly.

[0038] Through the above scheme, the first conveying device 2 conveys the shaft core to the first workstation, the second conveying device 3 conveys the housing to the second workstation, the handling device 6 transports the shaft core from the first workstation to the assembly device 4, the assembly device 4 assembles multiple shaft cores into a shaft system assembly, the handling device 6 transports the shaft system assembly to the second workstation and performs the shaft system boxing operation, and the second conveying device 3 transports the housing with the assembled shaft system assembly to the next workstation. By performing the shaft system boxing operation through various automated devices, the work efficiency is higher.

[0039] Specifically, in the clamping device 1, the clamping mechanism 15 is used to clamp each shaft core in the shaft assembly. The transport device 6 transports the clamping device 1 to the top of the housing and then drives the clamping device 1 downward to drive the shaft assembly into the housing. During the transport process, due to the floating mechanism 13, the second support plate 12 can move up and down and horizontally relative to the first support plate 11. If the clamping device 1 accidentally deviates slightly during the descent and accidentally hits the inner wall of the housing, the second support plate 12 will move by itself to compensate for the deviation, instead of moving directly downward, thus avoiding long-term rigid contact with the inner wall of the housing, preventing damage to the housing, and improving the safety of the shaft assembly entering the housing.

[0040] In some embodiments, such as Figures 3 to 5 As shown, the floating mechanism 13 includes a first fixed seat 131, a second fixed seat 132, a floating column 133, a first positioning sleeve 134, a second positioning sleeve 135, a floating limit member 136, and a floating spring 137.

[0041] The first fixed seat 131 is fixedly connected to the first support plate 11, and the second fixed seat 132 is fixedly connected to the second support plate 12. The floating column 133 passes vertically through the first positioning sleeve 134, the first fixed seat 131, the first support plate 11, the second positioning sleeve 135, the second fixed seat 132, and the second support plate 12. There is a gap between the outer wall of the floating column 133 and the inner wall of the first fixed seat 131, and there is a gap between the outer wall of the floating column 133 and the inner wall of the second fixed seat 132. The first positioning sleeve 134 is inserted into the first fixed seat. On the upper side of 131, the floating column 133 is provided with a first limiting step, which abuts against the lower end of the first positioning sleeve 134. The second positioning sleeve 135 is connected to the second fixed seat 132. The floating column 133 is provided with a second limiting step, which abuts against the upper end of the second positioning sleeve 135. Both ends of the floating column 133 are provided with floating limiting members 136 to restrict the floating column 133 from disengaging from the first positioning sleeve 134 and the second positioning sleeve 135. The two ends of the floating spring 137 apply elastic force to the first support plate 11 and the second support plate 12 respectively.

[0042] Specifically, the cross-sections of the first fixed seat 131 and the second fixed seat 132 are both T-shaped. The first fixed seat 131 is inserted into the first support plate 11 from top to bottom and the two are not fixed to each other. The second fixed seat 132 is inserted into the second support plate 12 from top to bottom and can be fixed to each other. The cross-section of the first positioning sleeve 134 is T-shaped and can be inserted into the first fixed seat 131 from top to bottom. The second positioning sleeve 135 is sleeved on the floating column 133. The lower surface of the second positioning sleeve 135 abuts against the second support plate 12. Both the upper and lower ends of the floating column 133 are provided with floating limit members 136 to restrict the floating column 133 from detaching from the first positioning sleeve 134 and the second positioning sleeve 135, that is, to prevent the floating column 133 from falling downward or leaving the entire floating mechanism 13 upward.

[0043] In some embodiments, the floating limiter 136 is a nut, threadedly connected to the end of the floating column 133, which is very convenient for both disassembly and installation.

[0044] In some embodiments, such as Figure 2 and Figure 3 As shown, the clamping device 1 also includes a clamping support column 16. One end of the clamping support column 16 is connected to the second support plate 12, and the other end of the clamping support column 16 extends downward and can abut against the positioning point on the box body, making the operation more accurate.

[0045] Specifically, during the box loading process, the dimensions of the box may have slight errors, meaning the internal thickness of the box may be inconsistent. Consequently, the descent position of the entire clamping device 1 will also be inconsistent. When dealing with slightly thicker boxes, if the clamping device 1 continues to move downwards, the second support plate 12 will drag the clamping support column 16 along with it, potentially damaging the box. This technical problem can be solved by setting up a floating mechanism 13.

[0046] When dealing with slightly thicker boxes, if the clamping support column 16 below the second support plate 12 has already touched the box, the box will push against the clamping support column 16 and the second support plate 12, and the first support plate 11 will continue to move downward. Since the floating column 133 and the first positioning sleeve 134 are not fixed relative to the first support plate 11, even if the second support plate 12 does not move, the first support plate 11 can continue to move downward. That is to say, even if the handling device 6 is still moving, it will not use the same force to drive the second support plate 12 and the clamping support column 16 downward, which can reduce damage to the box and avoid damaging the box, making the box insertion safer.

[0047] In addition, there is a gap between the outer wall of the floating column 133 and the inner wall of the first fixed seat 131, and a gap between the outer wall of the floating column 133 and the inner wall of the second fixed seat 132. Through these two gaps, a certain floating space can be provided for the first support plate 11 and the second support plate 12 in the horizontal direction. During the transportation process, due to the floating mechanism 13, the second support plate 12 can move up and down and in the horizontal direction relative to the first support plate 11. If the clamping device 1 accidentally deviates slightly during the descent and accidentally hits the inner wall of the box, the second support plate 12 will move horizontally to compensate for the deviation, instead of moving directly downward, thus avoiding long-term rigid contact with the inner wall of the box, avoiding damage to the box, and improving the safety of the shaft system entering the box.

[0048] In some embodiments, such as Figure 5 As shown, the floating mechanism 13 also includes a first thrust ball bearing 138 and a second thrust ball bearing 139. The first thrust ball bearing 138 and the second thrust ball bearing 139 are both located inside the second positioning sleeve 135 and are respectively located on the upper and lower sides of the second fixed seat 132.

[0049] Specifically, the second positioning sleeve 135 is a bearing sleeve, and the first thrust ball bearing 138 and the second thrust ball bearing 139 are both located inside the second positioning sleeve 135. While playing a positioning role, the second positioning sleeve 135 can also protect the first thrust ball bearing 138 and the second thrust ball bearing 139.

[0050] In some embodiments, such as Figures 3 to 5As shown, the floating mechanism 13 also includes a floating protective sleeve 1310, a floating spring 137 sleeved on the floating column 133, a floating protective sleeve 1310 sleeved on the floating spring 137, a spring support part 1311 inside the floating protective sleeve 1310, one end of the floating spring 137 is engaged with the spring support part 1311, the other end of the floating spring 137 abuts against the second positioning sleeve 135, one end of the floating protective sleeve 1310 abuts against the first positioning sleeve 134, and there is a gap between the other end of the floating protective sleeve 1310 and the second positioning sleeve 135.

[0051] Specifically, the lower end of the floating spring 137 abuts against the second positioning sleeve 135, the upper end of the floating spring 137 is engaged with the spring support 1311, and the elastic force of the floating spring 137 drives the floating protective sleeve 1310 to maintain an upward trend and abut against the lower end face of the first fixed seat 131.

[0052] More specifically, during the box loading process, the dimensions of the box may have slight errors, meaning the internal thickness of the box may be inconsistent. Consequently, the descent position of the entire clamping device 1 will also be inconsistent. When dealing with slightly thicker boxes, if the clamping device 1 continues to move downwards, the second support plate 12 will drag the clamping support column 16 along with it, potentially damaging the box. This technical problem can be solved by setting up a floating mechanism 13.

[0053] When dealing with slightly thicker boxes, if the clamping support column 16 below the second support plate 12 has already touched the box, the box will push against the clamping support column 16 and the second support plate 12, and the first support plate 11 will continue to move downward. Since the floating column 133 and the first positioning sleeve 134 are not fixed relative to the first support plate 11, even if the second support plate 12 does not move, the first support plate 11 can continue to move downward. That is to say, even if the handling device 6 is still moving, it will not use the same force to drive the second support plate 12 and the clamping support column 16 downward, which can reduce damage to the box and avoid damaging the box, making the box insertion safer.

[0054] After the box is filled, the first support plate 11 and the second support plate 12 will return to their original positions under the elastic force of the floating spring 137, so that the next box filling work can be carried out, which is more automated.

[0055] In some embodiments, such as Figure 2 , Figure 6 and Figure 7As shown, the locking mechanism 14 includes a locking support 141, a locking cylinder 142, a locking floating joint 143, and a locking pin 144. The second support plate 12 is provided with a locking hole 121. The locking support 141 is connected to the first support plate 11 and located on the lower side of the first support plate 11. The locking cylinder 142 is provided on the locking support 141. The locking cylinder 142 is connected to the locking pin 144 through the locking floating joint 143 to drive the locking pin 144 to extend into or leave the locking hole 121.

[0056] Specifically, during the box loading operation, the box body may deviate. At this time, the locking pin 144 is in the position away from the locking hole 121. The first support plate 11 and the second support plate 12 can float in the horizontal direction. When picking up the shaft assembly, since the shaft assembly has higher precision, there is no need for floating displacement to compensate for the error. The locking cylinder 142 drives the locking pin 144 to move downward and insert into the locking hole 121. At this time, the first support plate 11 and the second support plate 12 cannot float in the horizontal direction, but they can still float in the vertical direction to a certain extent, leaving room for adjustment and achieving a higher degree of automation.

[0057] In some embodiments, such as Figure 3 As shown, the clamping mechanism 15 includes a clamping displacement cylinder 151, a clamping support plate 152, and multiple shaft clamping assemblies 153. The second support plate 12 has a clamping clearance hole in the middle. The clamping displacement cylinder 151 is located on the first support plate 11 and is connected to the clamping support plate 152 to drive the clamping support plate 152 to move. Multiple shaft clamping assemblies 153 are all located on the clamping support plate 152.

[0058] Specifically, the second support plate 12 has a space in the middle to allow the clamping mechanism 15 to move up and down, so that the clamping mechanism 15 can grasp the shaft core. More specifically, the shaft core clamping assembly 153 is a commonly used shaft core clamp, which will not be described in detail here.

[0059] In some embodiments, such as Figure 3 As shown, the clamping mechanism 15 also includes a clamping guide post 154 and a clamping guide sleeve 155. The clamping guide sleeve 155 is disposed on the clamping support plate 152, and the clamping guide post 154 is disposed on the second support plate 12. The clamping guide sleeve 155 is sleeved on the clamping guide post 154 and can move along the axial direction of the clamping guide post 154. Specifically, by setting the clamping guide sleeve 155 and the clamping guide post 154, the shaft core clamping assembly 153 can be better guided to move in the vertical direction, and the shaft core can be picked up more accurately.

[0060] In some embodiments, such as Figure 3As shown, the clamping mechanism 15 also includes a clamping detection seat 156 and a clamping detection element 157. The clamping detection seat 156 is disposed on the second support plate 12 and located on the lower side of the second support plate 12. The clamping detection element 157 is disposed on the clamping detection seat 156 to detect whether the shaft clamping assembly 153 clamps the corresponding shaft.

[0061] Specifically, the fixture detection element 157 is a laser sensor. The number of fixture detection elements 157 is greater than or equal to the number of shaft core fixture assemblies 153, which can better detect whether the shaft core fixture assembly 153 has picked up a shaft core, and has a higher degree of intelligence.

[0062] It is understood that in some other embodiments, the clamp detection element 157 may also be a sensor capable of detecting objects, such as a proximity switch.

[0063] In some embodiments, such as Figure 3 and Figure 8 As shown, the clamping device 1 also includes a pressure detection mechanism 17, which includes a pressure detection seat 171, a pressure detection sleeve 172, a pressure detection pin 173, a pressure detection spring 174, and a pressure sensor 175. The pressure detection seat 171 is disposed on the second support plate 12 and located on the lower side of the second support plate 12. The pressure detection sleeve 172 is disposed on the pressure detection seat 171 and extends downward. The pressure sensor 175 is disposed inside the pressure detection sleeve 172. The pressure detection pin 173 is movably connected to the pressure detection sleeve 172 and can abut against the pressure sensor 175. One end of the pressure detection spring 174 is connected to the pressure detection pin 173, and the other end of the pressure detection spring 174 is connected to the pressure detection sleeve 172.

[0064] Specifically, during the box loading process, the dimensions of the box may have slight errors, meaning the internal thickness of the box may be inconsistent. Consequently, the descent position of the entire clamping device 1 will also be inconsistent. When dealing with slightly thicker boxes, if the clamping device 1 continues to move downwards, the second support plate 12 will drag the clamping support column 16 along with it, potentially damaging the box. This technical problem can be solved by setting up a floating mechanism 13.

[0065] Furthermore, when dealing with slightly thicker boxes, if the clamping support column 16 below the second support plate 12 has already touched the box, the box will push against the clamping support column 16 and the second support plate 12, and the first support plate 11 will continue to move downward. Since the floating column 133 and the first positioning sleeve 134 are not fixed relative to the first support plate 11, even if the second support plate 12 does not move, the first support plate 11 can continue to move downward. That is to say, even if the handling device 6 is still moving, it will not use the same force to drive the second support plate 12 and the clamping support column 16 downward, which can reduce damage to the box and avoid damaging the box, making the box insertion safer.

[0066] Furthermore, when the pressure detection pin 173 below the second support plate 12 abuts against the bottom of the box, if the clamping device 1 is still moving downward, the pressure detected by the pressure sensor 175 will increase. The pressure sensor 175 will transmit the detection data to the industrial control computer. If the detection data reaches the preset value, it indicates that the clamping device 1 or the robot arm has malfunctioned. At this time, the machine will be stopped immediately to avoid further damage to the box, thus ensuring higher safety.

[0067] Embodiments of the present invention also provide a method for shaft system loading into a housing, which, using the aforementioned shaft system loading equipment, offers high loading efficiency and high operational safety.

[0068] An embodiment of the present invention provides a method for mounting a shaft system in a housing, comprising the following steps: S1. The first conveying device 2 conveys the shaft core to the first workstation, and the second conveying device 3 conveys the box body to the second workstation; S2. The conveying device 6 moves the shaft core from the first station to the assembly device 4; S3, Assembly device 4 assembles multiple shaft cores and assembles them into a shaft system assembly; S4. The conveying device 6 moves the shaft assembly to the second station and performs the shaft assembly box insertion operation; S5. The second conveying device 3 transports the housing with the shaft assembly already assembled to the next work station.

[0069] Specifically, in step S1, the first conveying device 2 is used to convey the shaft cores. The first conveying device 2 includes a first conveyor belt and a first conveying tray. Multiple shaft cores are placed on the first conveying tray. The first conveyor belt conveys the first conveying tray to the first work station, which is the work station when the handling device 6 handles the shaft cores.

[0070] Furthermore, the second conveying device 3 is used to convey the box. The second conveying device 3 includes a second conveyor belt and a second conveying pallet. The box is placed on the second conveying pallet. The second conveyor belt conveys the second conveying pallet to the second work station, which is the work station where the handling device 6 performs the shaft system box insertion operation.

[0071] The above description is only a partial embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
