[0039] The utility model will be described in detail below in combination with the embodiments shown in the drawings. However, the embodiments do not limit the utility model, and the changes in mechanism, method or function made by those skilled in the art based on the embodiments are all included in the protection scope of the utility model.

[0040] The terms such as "upper", "lower", "left", "right", "front", "back", etc. used herein to indicate spatial relative positions are for the purpose of facilitating illustration to describe the relationship of one feature relative to another feature as shown in the drawings. It can be understood that the terms of spatial relative positions can be intended to include different orientations other than the orientation shown in the drawings, and should not be construed as limiting the claims. In addition, the descriptive word "horizontal" used herein is not completely equivalent to along the direction perpendicular to the direction of gravity, and a certain angle of inclination is allowed.

[0041] As shown in Figure 1 The first screw rod 210 is arranged in the screw rod sleeve 200, and the screw rod sleeve 200 is provided with a matching structure matched with the first screw rod 210. The first screw rod 210 is used to keep the matching structure at a preset position in the screw rod sleeve 200. In the process of assembling and manufacturing the planetary ball screw, the screw rod sleeve and the screw rod are usually matched and assembled. The first screw rod 210 is usually provided in the incoming semi-finished product of the planetary ball screw. When assembling, the first screw rod 210 is screwed out of the screw rod sleeve 200, and the second screw rod 220 is screwed into the screw rod sleeve 200, thereby completing the assembly of the required planetary ball screw. The second screw rod 220 and the first screw rod 210 have the same thread structure, and the matching structure can still be kept at the preset position in the screw rod sleeve 200 after the first screw rod 210 is withdrawn, thereby completing the switching of the screw rod in different models of products, including but not limited to length, shape structure, etc. In this paper, the first screw rod 210 is screwed out of the screw rod sleeve 200, which means that the first screw rod 210 is screwed out of the matching structure in the screw rod sleeve 200, and the second screw rod 220 is screwed into the screw rod sleeve 200, which means that the second screw rod 220 is screwed into the matching structure in the screw rod sleeve 200.

[0042] As shown in Figures 2-8 An embodiment of the utility model provides a kind of assembly equipment 100, which is used to automatically screw out first screw rod 210 from screw rod sleeve 200 and screw second screw rod 220 into screw rod sleeve 200. Figure 2 In the coordinate system shown in the upper right corner, the X-axis direction is the transverse direction of the assembly equipment 100, the Y-axis direction is the longitudinal direction of the assembly equipment 100, and the Z-axis direction is the up-down direction of the assembly equipment 100. The up-down direction, the longitudinal direction and the transverse direction are perpendicular to each other.

[0043] The assembly equipment 100 includes a platform 10 for placing the screw rod sleeve 200, a first operation module 20 located above the platform 10, and a second operation module 30 located below the platform 10. When the screw rod sleeve 200 is placed on the platform 10, the first screw rod 210 is connected thereto. The platform 10 is provided with a through hole (not shown in the figure) through which the first screw rod 210 can pass downward through the platform 10.

[0044] The first operation module 20 comprises a first clamping jaw 21 for clamping the second screw rod 220, and a first driving assembly 22 for driving the first clamping jaw 21 to move relative to the platform 10 at least in the up-down direction. The second operation module 30 comprises a clamping and rotating assembly 31 for clamping and rotating the first screw rod 210, and a second driving assembly 32 for driving the clamping and rotating assembly 31 to move relative to the platform 10 at least in the up-down direction.

[0045] The process of screwing the first screw rod 210 out of the screw rod sleeve 200 and screwing the second screw rod 220 into the screw rod sleeve 200 using the assembling device 100 is as follows: first, the screw rod sleeve 200 is placed on the platform 10, at this time, the first screw rod 210 is connected to the screw rod sleeve 200 and passes through the platform 10 downward through the through hole; then, the first clamping jaw 21 clamps the second screw rod 220, and the first driving assembly 22 drives the first clamping jaw 21 to carry the second screw rod 220 to the position directly above the screw rod sleeve 200; then, the clamping and rotating assembly 31 clamps and rotates the first screw rod 210, and at the same time, the second driving assembly 32 drives the clamping and rotating assembly 31 to move downward to screw the first screw rod 210 out of the screw rod sleeve 200 by a distance; after the first screw rod 210 is screwed out of the screw rod sleeve 200 by a distance, the first driving assembly 22 drives the first clamping jaw 21 downward to make the second screw rod 220 inserted into the screw rod sleeve 200; then, the clamping and rotating assembly 31 continues to rotate the first screw rod 210, and at the same time, the second driving assembly 32 drives the clamping and rotating assembly 31 to move downward to continue to screw the first screw rod 210 out of the screw rod sleeve 200 until the first screw rod 210 is separated from the screw rod sleeve 200, in the process of screwing the first screw rod 210 out of the screw rod sleeve 200, the matching structure inside the screw rod sleeve 200 rotates, at this time, the first driving assembly 22 drives the first clamping jaw 21 to move downward to make the first screw rod 210 screwed into the matching structure.

[0046] The assembling device 100 further comprises a first floating structure 40 connecting the first clamping jaw 21 and the first driving assembly 22, which is used for enabling the first clamping jaw 21 to float up and down relative to the first driving assembly 22. When the first clamping jaw 21 clamps the second screw rod 220, when the first driving assembly 22 drives the first clamping jaw 21 to move downward to make the second screw rod 220 inserted into the screw rod sleeve 200, the first clamping jaw 21 will float upward relative to the first driving assembly 22 to a preset position under the action of the screw rod sleeve 200, that is, when the first clamping jaw 21 floats upward relative to the first driving assembly 22 to the preset position, it can be explained that the first clamping jaw 21 clamps the second screw rod 220, if the first clamping jaw 21 does not clamp the second screw rod 220, the first driving assembly 22 drives the first clamping jaw 21 to move downward, and the first clamping jaw 21 will not float upward relative to the first driving assembly 22.

[0047] In the embodiment, the assembling device 100 further comprises a position sensing element 50 for sensing whether the first clamping jaw 21 is floated upward to a preset position relative to the first driving assembly 22. Through the position sensing element 50, it can be judged whether the second screw rod 220 is clamped on the first clamping jaw 21 after the first driving assembly 22 drives the first clamping jaw 21 to move downward.

[0048] As shown in Figure 4 , 6 , specifically, the first driving assembly 22 comprises a support 221 fixedly arranged relative to the platform 10, a transverse moving seat 222 movably arranged relative to the support 221 along a transverse direction, a first driving member 223 for driving the transverse moving seat 222 to move relative to the support 221 along the transverse direction, a first up-down moving seat 224 movably arranged relative to the transverse moving seat 222 along an up-down direction, a second driving member 225 for driving the first up-down moving seat 224 to move relative to the transverse moving seat 222 along the up-down direction, and the first floating structure 40 is connected to the first clamping jaw 21 and the first up-down moving seat 224.

[0049] As can be seen, under the driving of the first driving member 223 and the second driving member 225, the first clamping jaw 21 can move along the up-down direction and the transverse direction, so that the first clamping jaw 21 can carry the second screw rod 220 from a certain position to above the screw rod sleeve 200, and drive the second screw rod 220 to move downward, so that the second screw rod 220 can be screwed into the screw rod sleeve 200.

[0050] In order to limit the moving range of the transverse moving seat 222 in the transverse direction, two first limit members 226 are connected to the support 221, and the two first limit members 226 are respectively located on both sides of the transverse moving seat 222 in the transverse direction. By adjusting the positions of the two first limit members 226 in the transverse direction, the moving range of the transverse moving seat 222 in the transverse direction can be adjusted.

[0051] As shown in Figure 7 , the first floating structure 40 specifically comprises a connecting rod 41, a limiting block 42 and an elastic member 43. The connecting rod 41 passes through the first up-down moving seat 224 and is slidingly connected to the first up-down moving seat 224 along the up-down direction. The limiting block 42 is connected to the upper end of the connecting rod 41, and the limiting block 42 can prevent the connecting rod 41 from passing downward out of the first up-down moving seat 224. The lower end of the connecting rod 41 is connected to the first clamping jaw 21. The elastic member 43 is elastically and retractably arranged along the up-down direction, and the upper and lower ends of the elastic member 43 abut against the first up-down moving seat 224 and the first clamping jaw 21, respectively.

[0052] Because the connecting rod 41 is slidably connected to the first vertically movable seat 224 in the vertical direction, and the lower end of the connecting rod 41 is connected to the first clamping member 21, the first clamping member 21 can float up and down relative to the first vertically movable seat 224. When the first clamping member 21 is subjected to force and floats upward relative to the first vertically movable seat 224, the elastic member 43 contracts. After floating upward, when the first clamping member 21 is no longer subjected to force, the first clamping member 21 floats downward under the action of the elastic member 43. Specifically, two connecting rods 41 can be provided, and the elastic member 43 can be two compression springs respectively sleeved on the outer periphery of the two connecting rods 41. The limit block 42 connects the two connecting rods 41.

[0053] like Figure 8 As shown, the first clamping member 21 includes two clamping jaws 211 arranged opposite to each other, and a clamping jaw body 212 for driving the two clamping jaws 211 to open and close so that the two clamping jaws 211 can clamp and release the second screw rod 220. The two clamping jaws 211 are connected to the clamping jaw body 212. The first clamping member 21 also has a pressing block 213 connected to the clamping jaw body 212 and located between the two clamping jaws 211. When the two clamping jaws 211 clamp the second screw rod 220, the pressing block 213 can press the second screw rod 220. When the second screw rod 220 clamped by the two clamping jaws 211 is inserted into the screw rod sleeve 200, the two clamping jaws 211 can open. Thereafter, when the first driving assembly 22 drives the first clamping member 21 downward, the pressing block 213 moves downward with it, pressing down the second screw rod 220. Under the action of the pressing block 213, the second screw rod 220 moves downward and rotates, thereby being screwed into the screw rod sleeve 200.

[0054] In other embodiments, after the second screw rod 220 is inserted into the screw rod sleeve 200, it is not necessary to press down the pressure block 213. During the process of rotating and screwing out the first screw rod 210, the matching structure inside the screw rod sleeve 200 will rotate as the first screw rod 210 rotates, and then drive the second screw rod 220 connected to the matching structure to rotate, thereby realizing the screwing in of the second screw rod 220.

[0055] In this embodiment, the position sensing element 50 is disposed on one side of the limit block 42. The limit block 42 is provided with a sensing portion 421 for cooperating with the position sensing element 50. When the first clamping jaw 21 floats up and down relative to the first vertically movable seat 224, the sensing portion 421 also floats up and down accordingly. When the first clamping jaw 21 floats upward relative to the first vertically movable seat 224 to a preset position, the sensing portion 421 moves to a sensing position corresponding to the position sensing element 50 so that the position sensing element 50 can sense the sensing portion 421. In other words, when the position sensing element 50 senses the sensing portion 421, it indicates that the first clamping jaw 21 has floated upward relative to the first vertically movable seat 224 to the preset position. The position sensing element 50 can specifically be a proximity sensor.

[0056] In other embodiments, the sensing portion 421 is not limited to being arranged on the limiting block 42, and the sensing portion 421 can also be arranged on the first clamping jaw member 21, and in this case, the position sensing element 50 is arranged on one side of the first clamping jaw member 21.

[0057] In this embodiment, the platform 10 includes a base plate 11, a first carrier 12 arranged on the base plate 11 and used for placing the second lead screw 220, and a second carrier 13 arranged on the base plate 11 and used for placing the lead screw sleeve 200. Before the assembly device 100 starts to work, the second lead screw 220 needs to be placed in the first carrier 12 in advance, and the lead screw sleeve 200 needs to be placed in the second carrier 13. After that, the first driving assembly 22 drives the first clamping jaw member 21 to move in the upward and downward direction and the lateral direction, and carries the second lead screw 220 in the first carrier 12 to above the lead screw sleeve 200.

[0058] The assembly device 100 further includes a first sensing element 14 arranged on one side of the first carrier 12 and a second sensing element 15 arranged on one side of the second carrier 13. The first sensing element 14 is used for sensing whether the second lead screw 220 is in the first carrier 12, and the second sensing element 15 is used for sensing whether the lead screw sleeve 200 is in the second carrier 13. When it is sensed that the second lead screw 220 is in the first carrier 12 and the lead screw sleeve 200 is in the second carrier 13, the first operation module 20 and the second operation module 30 can start to act.

[0059] The first sensing element 14 can be connected to the platform 10 through a first adjusting support 16, and the position of the first sensing element 14 can be adjusted by adjusting the first adjusting support 16, so that the first sensing element 14 can sense whether the second lead screw 220 is in the first carrier 12. Similarly, the second sensing element 15 can be connected to the platform 10 through a second adjusting support 17, and the position of the second sensing element 15 can be adjusted by adjusting the second adjusting support 17, so that the second sensing element 15 can sense whether the lead screw sleeve 200 is in the second carrier 13. The first sensing element 14 and the second sensing element 15 can be photoelectric sensors.

[0060] As Figure 5 , 9As shown, in the embodiment, the clamping and rotating assembly 31 comprises a second clamping jaw 311 for clamping the first screw rod 210, a rotating driving member 312 for driving the second clamping jaw 311 to rotate, the second clamping jaw 311 is used for clamping the first screw rod 210, and the rotating driving member 312 drives the second clamping jaw 311 to rotate, so as to drive the first screw rod 210 to rotate. The clamping and rotating assembly 31 further comprises a second floating structure 313 connected between the second clamping jaw 311 and the rotating driving member 312, and the second floating structure 313 is used for enabling the second clamping jaw 311 to float up and down relative to the rotating driving member 312. When the rotating driving member 312 works, the second floating structure 313 and the second clamping jaw 311 are simultaneously driven to rotate.

[0061] As shown in Figure 1 , the combination of the first screw rod 210 and the screw rod sleeve 200 can be regarded as a half-finished product, wherein a part of the first screw rod 210 is located in the screw rod sleeve 200, and the other part extends out of the screw rod sleeve 200, and for a plurality of different such half-finished products, the lengths of the first screw rods 210 extending out of the screw rod sleeve 200 are also different. The above-mentioned arrangement that the second clamping jaw 311 can float up and down relative to the rotating driving member 312 can enable the second clamping jaw 311 to adapt to clamping the first screw rods 210 with different lengths extending out of the screw rod sleeve 200.

[0062] As shown in Figure 5 , 8 , the second driving assembly 32 comprises a support 321 fixed relative to the platform 10, a longitudinal moving seat 322 movably arranged relative to the support 321 along the longitudinal direction, a third driving member 323 for driving the longitudinal moving seat 322 to move relative to the support 321 along the longitudinal direction, a second up-and-down moving seat 324 movably arranged relative to the longitudinal moving seat 322 along the up-and-down direction, and a fourth driving member 325 for driving the second up-and-down moving seat 324 to move relative to the longitudinal moving seat 322 along the up-and-down direction. The clamping and rotating assembly 31 is connected to the second up-and-down moving seat 322.

[0063] As can be seen, under the driving of the third driving member 323 and the fourth driving member 325, the clamping and rotating assembly 31 can move along the up-and-down direction and the longitudinal direction, so that the first screw rod 210 clamped by the clamping assembly can move along the up-and-down direction and the longitudinal direction, thus the first screw rod 210 can be screwed out of the screw rod sleeve 200, and after the first screw rod 210 is screwed out of the screw rod sleeve 200, the first screw rod 210 can be moved to a designated position so as to be manually taken off from the clamping and rotating assembly 31.

[0064] To limit the moving range of the longitudinal moving seat 322 in the longitudinal direction, two second limiters 326 are connected to the support 321, and are respectively located at two sides of the longitudinal moving seat 322 in the longitudinal direction. By adjusting the positions of the two second limiters 326 in the longitudinal direction, the moving range of the longitudinal moving seat 322 in the longitudinal direction can be adjusted.

[0065] In other embodiments, the second floating structure 313 can also be connected to the second up-down moving seat 324 and the rotating driving member 312. In this way, the second clamping jaw member 311 can also be up-down floating.

[0066] In the embodiment, the second clamping jaw member 311 is a pneumatic clamping jaw, and a magnetic switch for detecting the opening and closing state of the second clamping jaw member 311 is further arranged on the second clamping jaw member 311. The assembling device 100 further comprises a gas-electric slip ring 60 connected to the second driving assembly 32. The second clamping jaw member 311 is connected to an external air source through the gas-electric slip ring 60, and the magnetic switch is electrically connected to an external control device through the gas-electric slip ring 60.

[0067] The second clamping jaw member 311 is connected to the external air source through the gas-electric slip ring 60, that is, the second clamping jaw member 311 and the gas-electric slip ring 60 are connected through a first air pipe, the gas-electric slip ring 60 and the external air source are connected through a second air pipe, and the magnetic switch is electrically connected to the external control device through the gas-electric slip ring 60, that is, the magnetic switch and the gas-electric slip ring 60 are electrically connected through a first wire, and the gas-electric slip ring 60 and the external control device are electrically connected through a second wire. The gas-electric slip ring 60 is arranged so that when the second clamping jaw member 311 rotates, the air pipe connected to the second clamping jaw member 311 and the external air source will not be twisted and wound, and the wire connected to the magnetic switch and the external control device will not be twisted and wound. The gas-electric slip ring 60 can be connected to the second up-down moving seat 324.

[0068] In the embodiment, the first clamping jaw member 21 can also be a pneumatic clamping jaw, and the first driving member 223, the second driving member 225 and the third driving member 323 can all be telescopic air cylinders.

[0069] The assembling device 100 provided by the embodiment can clamp and rotate the first lead screw 210 by the clamping and rotating assembly 31, and drive the clamping and rotating assembly 31 to move downward by the second driving assembly 32, so that the first lead screw 210 can be screwed out of the lead screw sleeve 200. After the first lead screw 210 is screwed out of the lead screw sleeve 200 for a distance, the second lead screw 220 is driven into the lead screw sleeve 200 by the first clamping jaw 21.
