[0036] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with specific embodiments and the accompanying drawings. Identical components are represented by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings. The terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0037] Figure 1 This is a cross-sectional view of the drive mechanism used in a specific embodiment of this application. Figure 1 As shown, the drive mechanism 1 includes a transmission unit, a drive component, and a torque output shaft 105.

[0038] The drive mechanism 1 includes at least one transmission unit; when there are multiple transmission units, the same transmission structure can be used, and the drive can be achieved by adjusting the relative position or time difference between the two and the drive unit; different transmission structures can also be used, and the drive can be achieved by adjusting the direction of force transmission.

[0039] The driving component includes a power output end; a driving unit is connected to the power output end, and each transmission unit is connected to the driving unit for transmission; the power output end drives the driving unit to reciprocate, such as reciprocating swing, reciprocating movement, reciprocating rotation, etc.

[0040] The drive mechanism 1 includes at least one torque output shaft 105, and each torque output shaft 105 is drivenly connected to at least one transmission unit, each of which is capable of driving the torque output shaft 105 to move. Each transmission unit is used to drive the torque output shaft 105 to move in the same direction or in opposite directions.

[0041] During assembly, the piston rod is typically fixed by machine. The machine can fix the piston rods one by one, or multiple piston rods can be fixed simultaneously at intervals, and then the piston is assembled manually. Using the drive mechanism 1, the piston can be mounted on the torque output shaft 105. The drive component provides the driving force, which is transmitted to each transmission unit. The transmission units can drive the torque output shaft 105 to rotate one by one, or drive multiple torque output shafts 105 to rotate simultaneously, or continuously drive a specific torque output shaft 105 to rotate, thus achieving the assembly of the piston and piston rod.

[0042] The drive mechanism 1 described above drives the transmission unit through the drive unit. The transmission unit can drive the torque output shaft 105 to rotate one by one, or drive multiple torque output shafts 105 to rotate simultaneously, or drive a certain torque output shaft 105 to rotate continuously. The piston assembly action is realized through the rotation of the torque output shaft 105, which reduces the labor intensity of workers, improves production efficiency, and reduces energy consumption.

[0043] Optionally, the driving component can drive the driving unit to reciprocate. The transmission unit includes two units: a first transmission unit and a second transmission unit. During the reciprocating movement of the driving unit, the first and second transmission units are driven respectively. The first and second transmission units are used to drive the torque output shaft 105 to move in the same direction. The first transmission unit can be connected to the driving component and is used to transmit the driving force provided by the driving component, causing the torque output shaft 105 to perform a corresponding action. The second transmission unit can be connected to the driving component and is used to transmit the driving force provided by the driving component, causing the torque output shaft 105 to perform a corresponding action. The driving component drives the driving unit to reciprocate, such as reciprocating rotation. In the same motion cycle, when the driving unit rotates to one side, the driving force is transmitted through the first transmission unit; when the driving unit rotates to the other side, the driving force is transmitted through the second transmission unit.

[0044] The drive unit can drive the first transmission unit and the second transmission unit respectively, so that the torque output shaft 105 can be continuously driven. Specifically, the drive unit drives the first transmission unit to move in one direction, and the first transmission unit drives the torque output shaft 105 to move in that direction, such as to achieve a tightening action; the drive unit drives the second transmission unit to move in another direction, and the second rotation unit drives the torque output shaft 105 to move in the same direction as above, such as to achieve a tightening action; that is, during the reciprocating motion of the drive unit, the torque output shaft 105 always moves in the same direction, realizing continuous unidirectional rotation of the torque output shaft 105. With the above structure, in some applications, compared with the prior art which achieves one action in one motion cycle, i.e., intermittent action, this structure can achieve two actions, continuously achieving tightening action or continuously achieving loosening action, which can reduce the labor intensity of workers, improve production efficiency, and reduce energy consumption.

[0045] Optionally, the power output end includes a power shaft and a first base plate and a second base plate arranged relatively parallel to each other. The two ends of the power shaft are connected to a driving member and a driving unit, respectively. The power shaft extends through the first base plate, and a torque output shaft 105 is connected to the first base plate and extends through the second base plate. The power shaft serves as the power output component of the driving member. The driving unit is connected to the end of the power shaft extending from the driving member. The driving member can drive the power shaft to reciprocate, causing the driving unit to rotate. The power shaft passes through the first base plate and can rotate relative to it. The driving unit, the first transmission unit, and the second transmission unit are all disposed between the first and second base plates. The torque output shaft 105 is connected to either the first or second transmission unit and passes through the second base plate, allowing it to rotate relative to it. The second base plate is relatively longer than the first base plate and provides support for the mating component. Using the above-described power output end results in a relatively compact structure, occupies less space, and is easy to operate.

[0046] In one embodiment of this application, a support plate may be provided between the first substrate and the second substrate to ensure the stability of the power output end.

[0047] Optionally, the first transmission unit and the second transmission unit are respectively disposed on opposite sides of the drive unit. The first transmission unit provides driving force to the torque output shaft 105, and the second transmission unit provides a driving force with adjusted direction to the torque output shaft 105. With the first and second transmission units respectively disposed on opposite sides of the drive unit, the first and second transmission units respectively receive driving force from the drive unit in two directions. The first transmission unit directly transmits the driving force to the torque output shaft 105. After receiving the driving force, the second transmission unit adjusts the driving direction of the driving force during transmission and then transmits the adjusted driving force to the torque output shaft 105, enabling the first and second transmission units to drive the torque output shaft 105 to rotate in the same direction. This structure effectively utilizes the space between the first and second substrates, and also effectively utilizes the driving force provided by the drive component.

[0048] Optionally, the driving component is a swing structure, the driving unit is a driving gear 102, the first transmission unit is a transmission gear assembly, and the second transmission unit is a steering transmission gear assembly. When the swing structure rotates clockwise, it drives the driving gear 102 to rotate clockwise, which in turn drives the transmission gear assembly to rotate the torque output shaft 105 counterclockwise. When the swing structure rotates counterclockwise, it drives the driving gear 102 to rotate counterclockwise, which in turn drives the steering transmission gear assembly to rotate the torque output shaft 105 counterclockwise. This achieves reciprocating motion of the swing structure, with the torque output shaft 105 rotating in the same direction in all cases.

[0049] In one embodiment of this application, the swing structure includes, but is not limited to, a swing cylinder 101, and the torque output is controlled by the air source pressure of the swing cylinder 101. The torque can be arbitrarily adjusted within the maximum torque range output by the swing cylinder 101 through air pressure control.

[0050] Optionally, the transmission gear assembly includes a first transmission gear 103 and a first one-way bearing 106 connected to the first transmission gear 103; a drive gear 102 is drively connected to the first transmission gear 103; a torque output shaft 105 is connected to the first one-way bearing 106 and can rotate with the first transmission gear 103. The drive gear 102 meshes with the first transmission gear 103, the first transmission gear 103 is connected to the first one-way bearing 106, and is connected to the torque output shaft 105 through the first one-way bearing 106. When the swing structure rotates clockwise, it drives the drive gear 102 to rotate clockwise. The drive gear 102 meshes with the first transmission gear 103, causing the first transmission gear 103 to rotate counterclockwise. The first transmission gear 103 drives the torque output shaft 105 to rotate counterclockwise through the first one-way bearing 106. Using the above-described transmission gear assembly, the structure is relatively simple, easy to operate, has a timely response, and good accuracy.

[0051] Optionally, the steering transmission gear assembly includes a second transmission gear 104, a second one-way bearing, a drive shaft 107, a first steering gear 108, and a second steering gear 110; a drive gear 102 is drivingly connected to the second transmission gear 104; a second one-way bearing 109 is connected to the second transmission gear 104; the opposite ends of the drive shaft 107 are connected to a first base plate and a second base plate respectively; the drive shaft 107 is connected to the second one-way bearing 109 and can rotate with the second transmission gear 104; the first steering gear and the second steering gear 110 mesh with each other and are respectively connected to the drive shaft 107 and the torque output shaft 105. The drive gear 102 meshes with the second transmission gear 104; the second transmission gear 104 is connected to the second one-way bearing 109 and is connected to the drive shaft 107 through the second one-way bearing 109. The upper part of the drive shaft 107 is connected to the first steering gear; the first steering gear and the second steering gear 110 mesh; the second steering gear 110 is connected to the torque output shaft 105. The oscillating structure rotates counterclockwise, driving the drive gear 102 to rotate counterclockwise. The drive gear 102 meshes with the second transmission gear 104, which rotates clockwise. The second transmission gear 104, through the second one-way bearing 109, drives the transmission shaft 107 to rotate clockwise. The transmission shaft 107 drives the first steering gear to rotate clockwise. The first steering gear meshes with the second steering gear 110, which rotates counterclockwise. The second steering gear 110 is connected to the torque output shaft 105, driving the torque output shaft 105 to rotate counterclockwise. Using the above-described steering transmission gear assembly, the structure is relatively simple, easy to operate, responds promptly, and has good accuracy.

[0052] The following section further describes the usage process of drive mechanism 1.

[0053] The driving component is a swing structure. The driving gear 102 is mounted on the power shaft of the swing mechanism. The transmission gear assembly and the steering transmission gear assembly are respectively mounted on opposite sides of the driving gear 102. The swing structure can move clockwise first and then counterclockwise, or counterclockwise first and then clockwise. Taking the former as an example, the swing structure rotates clockwise, driving the driving gear 102 to rotate clockwise. The driving gear 102 meshes with the first transmission gear 103, which rotates counterclockwise. The first transmission gear 103 drives the torque output shaft 105 to rotate counterclockwise via the first one-way bearing 106. The driving gear 102 meshes with the second transmission gear 104, which is connected to the second one-way bearing 109 and, through the second one-way bearing 109, to the transmission shaft 107. The upper part of the transmission shaft 107 is connected to the first steering gear, which meshes with the second steering gear 110. The second steering gear 110 is connected to the torque output shaft 105. The oscillating structure rotates counterclockwise, driving the drive gear 102 to rotate counterclockwise. The drive gear 102 meshes with the second transmission gear 104, which rotates clockwise. The second transmission gear 104, through the second one-way bearing 109, drives the transmission shaft 107 to rotate clockwise. The transmission shaft 107 drives the first steering gear to rotate clockwise. The first steering gear meshes with the second steering gear 110, which rotates counterclockwise. The second steering gear 110 is connected to the torque output shaft 105, driving the torque output shaft 105 to rotate counterclockwise. Thus, the oscillating structure completes one drive cycle.

Figure 4 for Figure 2 A schematic diagram of the positioning mechanism of the assembly device shown. Figure 5 for Figure 4 Side view of the fixture of the positioning mechanism shown. Figure 6 for Figure 2 Another side view of the positioning element shown. (See image below.) Figures 2 to 6 As shown, this application also provides an assembly device, including: a drive mechanism 1 and a positioning mechanism 2.

[0055] The drive mechanism 1 is used to extract the first mating part; the drive mechanism 1 can adopt any of the above structures, which will not be described in detail here. The first mating part includes, but is not limited to, pistons, nuts, etc.

[0056] The positioning mechanism 2 is used to position the second mating component 204, and the driving mechanism 1 can drive the first mating component to move relative to the second mating component 204, so that the first mating component and the second mating component 204 are assembled into a single structure. The positioning mechanism 2 can keep the second mating component 204 in a relatively easy-to-install state. The second mating component 204 includes, but is not limited to, piston rods, bolts, etc.

[0057] In use, the positioning mechanism 2 can carry the second mating part 204 to a suitable assembly position and fix its position, and the driving mechanism 1 drives the first mating part to move relative to the second mating part 204 to complete the assembly of the first mating part and the second mating part 204.

[0058] Using the above-described assembly device, the first mating component and the second mating component 204 are respectively connected to the drive mechanism 1 and the positioning mechanism 2. The drive mechanism 1 can drive the first mating component to move relative to the second mating component 204 to achieve assembly. Moreover, during the assembly process, the drive mechanism 1 drives the transmission unit through the drive unit. The transmission unit can drive the torque output shaft 105 to rotate one by one, or drive multiple torque output shafts 105 to rotate simultaneously, or drive a certain torque output shaft 105 to rotate continuously. Through the rotation of the torque output shaft 105, the piston assembly action is realized, reducing the labor intensity of workers, improving production efficiency, and reducing energy consumption.

[0059] Optionally, the positioning mechanism 2 includes: a base, a worktable 201, a positioning element 205, two clamps 202, and a synchronization structure 203.

[0060] The positioning mechanism 2 includes a base; the worktable 201, fixture 202, etc. are all integrated on the base, and the base provides support for the worktable 201, etc.

[0061] The worktable 201 is mounted on the base and can reciprocate relative to the base; for example, the worktable 201 and the base are connected by slide rails and tracks. A push-pull mechanism is provided on one side of the worktable 201. When the push-pull mechanism is activated, the worktable 201 can perform linear reciprocating motion relative to the base with the assistance of the slide rails and tracks.

[0062] The positioning element 205 is used to position the second mating element 204. The positioning element 205 is located below the worktable 201 and the base, passing through the base. The worktable 201 has a through hole, and the positioning element 205 is positioned opposite the through hole. The second mating element 204 passes through the through hole and connects to the positioning element 205. The second mating element 204 and the positioning element 205 are detachably connected. The second mating element 204 has a wide range of lengths and large diameter variations. By replacing the positioning element 205, the application range of the positioning mechanism can be increased.

[0063] In one embodiment of this application, the positioning member 205 is vertically connected to the worktable 201 and the base. The base is provided with a lifting structure 209, which is connected to the positioning member 205 to drive the positioning member 205 to move up or down to approach or move away from the second mating member 204.

[0064] Two clamps 202 are symmetrically arranged on the worktable 201 around the positioning element 205; the two clamps 202 can move closer or further apart; when the two clamps 202 are close together, they can clamp the second mating element 204, fixing the position of the second mating element 204; when the two clamps 202 are far apart, they can release the second mating element 204. The two clamps 202 can adapt to various positioning and fixing of the second mating element 204.

[0065] In one embodiment of this application, the clamp 202 includes a hydraulic cylinder that extends close to the second mating member 204 and retracts away from the second mating member 204 when it extends.

[0066] The synchronization structure 203 is connected to the two clamps 202 respectively, so that the distance between the two clamps 202 and the center of the positioning component 205 is equal. By using the synchronization structure 203 to connect the two clamps 202, the synchronous operation of the two clamps 202 is ensured, thereby ensuring that the clamping center of the two clamps 202 is coaxial with the center of the second mating component 204, and improving the positioning accuracy.

[0067] First, the positioning mechanism 2 is activated; the second mating part 204 is passed through the through hole on the worktable 201 and installed on the positioning part 205; the push-pull mechanism on the base is activated, pushing the worktable 201 to move along the track, so that the two clamps 202 are respectively located on opposite sides of the second mating part 204. Simultaneously, the synchronization mechanism and the two clamps 202 are activated. Under the action of the synchronization mechanism, the two clamps 202 move towards the second mating part 204 simultaneously until the clamping center of the two clamps 202 coincides with the axis of the second mating part 204. Then, the drive mechanism 1 is activated; the swing structure rotates clockwise, driving the drive gear 102 to rotate clockwise, and the drive gear 102 drives the transmission gear assembly to rotate the torque output shaft 105 counterclockwise. The swing structure rotates counterclockwise, driving the drive gear 102 to rotate counterclockwise, and the drive gear 102 drives the steering transmission gear assembly to rotate the torque output shaft 105 counterclockwise.

[0068] In one embodiment of this application, the positioning mechanism 2 further includes a torque detector 206, which can detect the torque value provided by the drive mechanism 1. The torque detector 206 can ensure product quality. Both the torque detector 206 and the drive mechanism 1 are connected to a PLC control device for intelligent monitoring. For example, the torque value is detected by the torque detector 206 and fed back to the display; when the set value is reached, the PLC control device controls the opening and closing of the drive mechanism 1.

[0069] Optionally, the positioning mechanism 2 further includes a backup drive component 208 and a transmission component. The backup drive component 208 is connected to the transmission component, and the transmission component is connected to the positioning component 205. The torque provided by the backup drive component 208 is greater than the torque provided by the drive mechanism 1. When the torque provided by the drive mechanism 1 cannot meet the actual requirements, the drive mechanism 1, carrying the first mating component, remains relatively stationary. The backup drive component 208 is then activated to achieve a large torque output. The backup drive component 208 drives the positioning component 205 through the transmission component, thereby rotating the second mating component 204 and assembling the first and second mating components 204. Equipping the positioning mechanism 2 with a backup drive component 208 solves the problem of torque exceeding the range of the drive mechanism 1, meets different torque requirements, and increases the application range of the assembly device.

[0070] In one embodiment of this application, the transmission component includes, but is not limited to, the gear and rack assembly 207.

[0071] As can be seen from the above description and practice, the drive mechanism and assembly device provided in this application have the following advantages compared with the prior art: By adopting the above-mentioned drive mechanism, the drive mechanism drives the transmission unit through the drive unit. The transmission unit can drive the torque output shaft to rotate one by one, or drive multiple torque output shafts to rotate simultaneously, or drive a certain torque output shaft to rotate continuously. Through the rotation of the torque output shaft, the piston assembly action is realized, reducing the labor intensity of workers, improving production efficiency, and reducing energy consumption.

[0072] Those skilled in the art should understand that the above description is merely a specific embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the scope of this application should be included within the protection scope of this application.
