[0002] In the assembly process of automotive steering products, worm gears and worms need to be press-fitted. In the past, the assembly process mostly used manual or semi-automatic assembly, and the press-fitting was relatively complicated. As a result, some automated press-fitting equipment has emerged.

Detailed Implementation

[0034] 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.

[0035] The following is for reference. Figures 1-13 The press-fitting device 100 according to an embodiment of the present invention can realize the press-fitting structure 7 to press-fit the worm wheel 91 and worm 92 step by step. The press-fitting has a certain buffering property to prevent damage to the press-fitting worm wheel 91 and worm 92. After the worm wheel 91 and worm 92 are assembled in place, the elastic component 26 lifts the assembled worm wheel 91 and worm 92, which can facilitate the disassembly and removal of the installed worm wheel 91 and worm 92.

[0036] like Figures 1-13 A pressing device 100 according to an embodiment of the present invention is described. The pressing device 100 is used for pressing a worm gear 91 and a worm 92, and the pressing device 100 includes: a frame 1, a pressing structure 7 and a mounting structure 2.

[0037] The press-fitting structure 7 is used to apply a press-fitting force to the worm 92 so that the worm 92 is press-fitted into the worm wheel 91. The mounting structure 2 includes a support component 27, an elastic component 26, and a movable component 28. The support component 27 is mounted on the frame 1. The movable component 28 is movably mounted on the support component 27. The elastic component 26 is mounted between the support component 27 and the movable component 28. The movable component 28 is used to support the worm wheel 91 and the worm 92. The movable component 28 is adapted to move toward the support component 27 to compress the elastic component 26 when the press-fitting structure 7 presses the worm 92. The movable component 28 is also adapted to move away from the support component 27 under the elastic force of the elastic component 26 after the press-fitting structure 7 removes the press-fitting force.

[0038] In practice, the worm gear 91 and worm 92 serve as the tooling components 9 to be press-fitted. The worm gear 91 has a hollow hole, and the worm 92 is placed through the hollow hole of the worm gear 91. Both the worm gear 91 and the worm 92 are placed on the movable component 28. The press-fitting equipment 100 presses the worm 92, and during the press-fitting process, the worm 92 and the worm gear 91 are installed in place.

[0039] Specifically, the support component 27 is connected to the frame 1 and supports the movable component 28, making the movable component 28 equivalent to the support component 27 movable. The press-fit structure 7 presses the worm 92 located on the movable component 28. Since there is an elastic component 26 between the movable component 28 and the support component 27, the elastic force of the elastic component 26 is less than the pressing force of the press-fit structure 7. During the pressing process, it has a certain buffering force, which allows the press-fit structure 7 to press the movable component 28 gradually and slowly. After the worm 92 and the worm wheel 91 are pressed into place, the press-fit structure 7 is released. When the press-fit structure 7 is separated from the worm 92, the elastic component 26 lifts the worm 92. Since the worm wheel 91 and the worm 92 are already pressed into place, that is, the worm wheel 91 and the worm 92 are in an interference fit, the elastic component 26 can lift the worm 92 and the worm wheel 91 together, thereby facilitating the disassembly and installation of the worm wheel 91 and the worm 92.

[0040] Furthermore, the movable component 28 is configured to move relative to the support component 27. The support component 27 has space within it for the movable component 28 to move. This allows the press-fit structure 7 to have a certain space to move towards the support component 27 when pressing the worm 92. However, the space is limited, so that when the press-fit structure 7 initially presses the worm 92, the worm 92 moves towards the support component 27. As pressing continues, due to space limitations, the worm 92 and worm wheel 91 cannot continue to move towards the support component 27, and the worm 92 and worm wheel 91 are installed in place. However, when the movable component 28 moves towards the support component 27, the elastic component 26 provides an upward force to the movable component 28. This upward force can form a damping effect for pressing, which can satisfy the need for gradual and slow pressing and avoid the problem of damage to the worm 92 and worm wheel 91 caused by direct hard pressing.

[0041] Therefore, the pressing equipment 100 of this embodiment of the invention can achieve a certain degree of buffering during pressing to prevent damage to the worm wheel 91 and worm wheel 91 shaft during pressing, and after the worm wheel 91 and worm 92 are assembled in place, the elastic component 26 lifts the assembled worm wheel 91 and worm 92, which can facilitate the disassembly and installation of the worm wheel 91 and worm 92.

[0042] In some embodiments, the movable component 28 includes a first sleeve 24 and a second sleeve 25, the second sleeve 25 being partially located inside the first sleeve 24 and partially extending outside the first sleeve 24, the second sleeve 25 being slidable relative to the first sleeve 24, the first sleeve 24 being partially inserted into the support component 27, the end of the first sleeve 24 exposed outside the support component 27 being used to mount the worm gear 91, and the second sleeve 25 being used to extend into the worm 92.

[0043] In practice, the worm gear 91 is located at the end of the first sleeve 24, and the worm 92 extends into the second sleeve 25 through the hollow hole of the worm gear 91 located at the end of the first sleeve 24. The first sleeve 24 and the second sleeve 25 are elastically supported by the elastic component 26. Specifically, in the initial state, that is, when the worm gear 91 and the worm 92 are not installed on the movable component 28, the second sleeve 25 extends out of the first sleeve 24, and the part of the second sleeve 25 that extends out of the first sleeve 24 is the extension 252. When the worm gear 91 is placed at the end of the first sleeve 24, the worm gear 91 can be fitted onto the extension 252, thereby enhancing the installation stability of the worm gear 91 and preventing radial displacement of the worm gear 91.

[0044] Additionally, it facilitates the worm 92 extending into the second sleeve 25 along the extension 252 of the second sleeve 25, making it easier for the worm 92 to align with and extend into the second sleeve 25. When the worm 92 extends into the second sleeve 25, a portion of the worm 92 is still exposed above the worm wheel 91. The worm 92 is provided with a pressing platform 921, which presses against the top of the second sleeve 25 to press the worm 92 in place, facilitating direct pressing of the worm 92 by the pressing structure 7. Further, refer to... Figure 7 As shown, as the press-fitting structure 7 presses in the worm 92, and because the worm 92 and the worm wheel 91 are in an interference fit, the worm 92 needs to be subjected to a large pressing force that is greater than that of the elastic component 26. The worm 92 moves toward a position closer to the support component 27, and finally the worm 92 and the worm wheel 91 are gradually installed in place.

[0045] In addition, during the pressing process of the worm 92, the worm wheel 91 will also be driven downward to press the first sleeve 24. The first sleeve 24 moves to its limit position during the downward movement, which is also the position where the worm 92 and the worm wheel 91 are installed. The pressing structure 7 can judge the pressure. When there is a large resistance and it cannot move downward, it will maintain the pressure and then stop moving. Thus, when the first sleeve 24 and the second sleeve 25 are separated from the pressing structure 7, the elastic component 26 will lift the worm wheel 91 and the worm 92, making it easy to remove the worm 92 and the worm wheel 91.

[0046] In some embodiments, the frame 1 is provided with a limiting part 141, and the bottom of the support component 27 is provided with a through hole 244. When the press-fit structure 7 presses the worm 92 into place with the worm wheel 91, the bottom of the movable component 28 extends out of the through hole 244 and contacts and limits the limiting part 141.

[0047] Specifically, the limiting part 141 of the frame 1 is directly opposite the bottom of the support component 27 and the bottom of the movable component 28. That is, the mounting structure 2 moves to the position directly opposite the limiting part 141 for pressing. When the worm 92 is pressed to a certain extent and drives the first sleeve 24 to move downward, the bottom of the first sleeve 24 passes through the through hole 244 of the support component 27 and presses against the limiting part 141. When the pressing structure 7 determines that the resistance to pressing the worm 92 downward is large, the pressing structure 7 automatically separates from the worm 92.

[0048] In this way, by providing a through hole 244 at the bottom of the support component 27, the bottom of the first sleeve 24 selectively contacts the limiting part 141, which limits the range of motion of the first sleeve 24 and also limits the range of motion of the worm 92 and worm wheel 91 after they are pressed into place, thereby achieving better pressing of the worm 92 and worm wheel 91 into place.

[0049] In some embodiments, the elastic component 26 includes a first elastic element 261 and a second elastic element 262; the first elastic element 261 is sleeved outside the first sleeve 24 and connected between the top of the first sleeve 24 and the support component 27, and the second elastic element 262 is located at the inner bottom of the first sleeve 24 and supported by the second sleeve 25. When the press-fitting structure 7 presses the worm 92 and worm wheel 91 on the movable component 28, the first sleeve 24 compresses the first elastic element 261 and the second sleeve 25 compresses the second elastic element 262. When the press-fitting structure 7 is separated from the movable component 28, the first elastic element 261 exerts an upward force on the first sleeve 24, and the second elastic element 262 exerts an upward force on the second sleeve 25.

[0050] In practice, the first elastic element 261 supports the first sleeve 24, and the second elastic element 262 supports the second sleeve 25, allowing the first sleeve 24 and the second sleeve 25 to be supported independently. When the worm 92 is subjected to a pressing force, the second sleeve 25 descends, compressing the second elastic element 262 at the bottom of the second sleeve 25. During this compression, the first sleeve 24 descends. Furthermore, the worm 92 and the worm wheel 91 are interference-fitted, so when the worm 92 descends, it also causes the worm wheel 91 to press against the first sleeve 24, causing the first sleeve 24 to gradually descend. As the first sleeve 24 is pressed into place, the worm 92 inside the second sleeve 25 experiences greater resistance during the pressing process, thus preventing further pressing. Initially, the worm 92 and worm wheel 91 can be understood as a rough installation, and when the worm 92 is subjected to a downward force, the worm wheel 91 is also subjected to a certain downward force. The first elastic element 261 and the second elastic element 262 respectively provide a certain pressing buffer between the worm 92 and the worm wheel 91 during the cooperation process, until neither can move downwards, and finally the pressing is completed.

[0051] Similarly, when the press-fit structure 7 separates from the worm gear 92, refer to Figure 10 As shown, the second sleeve 25 is lifted by the second elastic element 262, thereby lifting the worm 92 by the second sleeve 25, and the first sleeve 24 is lifted by the first elastic element 261. Then the worm wheel 91 is lifted by the first sleeve 24, realizing the simultaneous separation of the worm 92 and the worm wheel 91, so that the assembled worm wheel 91 and worm 92 can be removed manually or by a robot.

[0052] Furthermore, the upper end of the first sleeve 24 is provided with a radially extending pressing part 245. The first elastic element 261 is a spring, which is sleeved on the outside of the first sleeve 24. One end is connected to the pressing part 245 of the first sleeve 24, and the other end is connected to the upper end face of the support assembly 27. The second elastic element 262 is also a spring. One end of the second elastic element 262 is provided on the bottom wall of the first sleeve 24, and the other end is connected to the bottom of the second sleeve 25. The bottom wall of the second sleeve 25 can be set as a detachable bottom plate 242, thereby facilitating the installation of the second elastic element 262.

[0053] In some embodiments, the support assembly 27 is provided with a first limiting boss 232, and the bottom of the first sleeve 24 is provided with a second limiting boss 243. When the first sleeve 24 is lifted and moved by the first elastic member 261, the second limiting boss 243 is adapted to contact the first limiting boss 232 to limit the upward movement of the first sleeve 24.

[0054] In practice, when the first sleeve 24 is pressed downwards and moves to contact the limiting part 141, it is the limit position of the downward movement of the first sleeve 24. When the first sleeve 24 moves upwards under the elastic force of the first elastic member 261 until the first limiting boss 232 contacts the second limiting boss 243, it is the maximum position where the first sleeve 24 is lifted. By setting the first limiting boss 232 and the second limiting boss 243, the first sleeve 24 is prevented from being pushed out under the action of the first elastic member 261. At the same time that the worm gear 91 and the worm 92 are lifted, the first sleeve 24 stops moving relative to the support assembly 27.

[0055] Specific reference Figure 4 As shown, the movable component 28 extends into the support component 27 and is movably connected to the support component 27. The support component 27 is provided with a first limiting boss 232. That is, the diameter of the support component 27 below the first limiting boss 232 is larger than the diameter of the support component 27 above the first limiting boss 232. At the same time, the bottom of the first sleeve 24, that is, the diameter of the bottom plate 242, is larger than the outer diameter of the first sleeve 24, thereby forming a second limiting boss 243 at the bottom of the first sleeve 24 to limit the upward movement of the first sleeve 24.

[0056] In some embodiments, the upper part of the second sleeve 25 is provided with a third limiting boss 251, and the upper inner side of the first sleeve 24 is provided with a fourth limiting boss 241. When the second elastic member 262 lifts the second sleeve 25, the third limiting boss 251 is adapted to make limiting contact with the fourth limiting boss 241.

[0057] Specifically, the upper diameter of the second sleeve 25 is smaller than the diameter of other parts of the second sleeve 25, so that the upper end of the second sleeve 25 forms a third limiting boss 251. At the same time, the upper end of the first sleeve 24 extends radially inward to form a fourth limiting boss 241. During the process of the second sleeve 25 being lifted by the second elastic member 262, the third limiting boss 251 and the fourth limiting boss 241 come into contact, so that the second sleeve 25 is lifted to a certain position and then stops, thereby preventing the second sleeve 25 from being pushed out.

[0058] In some embodiments, the pressing equipment 100 further includes a barcode scanning position. The frame 1 is provided with a barcode scanning structure 6, which is opposite to the barcode scanning position. The mounting structure 2 is connected to a drive structure 5, which drives the mounting structure 2 to move to the barcode scanning position, so that the barcode scanning structure 6 scans the worm gear 91 and worm 92 of the mounting structure 2.

[0059] In actual operation, the worm gear 92 and worm wheel 91 on the active component 28 are equipped with pre-set QR codes. For example, the QR code on the worm wheel 91 is engraved on the surface of the worm wheel 91 facing upwards, and the QR code on the worm gear 92 is also engraved on the surface of the worm gear 92 facing upwards. When the drive structure 5 drives the mounting structure 2 to the scanning position, the worm wheel 91 and worm gear 92 on the mounting structure 2 are driven to the scanning position, and the QR codes on the worm wheel 91 and worm gear 92 are opposite to the scanning structure 6, so that the scanning structure 6 scans the worm wheel 91 and worm gear 92. Furthermore, the scanning structure 6 can transmit the product model information obtained by scanning to the storage module for storage, thereby recording the product model information of the worm gear 92 through the QR code, which is convenient for later viewing and traceability of the product.

[0060] In some embodiments, the barcode scanning structure 6 includes a barcode scanner 61 and a rod assembly 62. One end of the rod assembly 62 is connected to the frame 1 and the other end is rotatably connected to the barcode scanner 61, so that the position of the barcode scanner 61 relative to the worm gear 91 and the worm 92 is adjustable.

[0061] Specifically, the barcode scanner 61 of the barcode scanning structure 6 is used to scan the worm gear 91 and worm 92. When the mounting structure 2 is moved to the scanning position, it may not be directly aligned with the barcode scanner 61 of the barcode scanning structure 6. Therefore, the barcode scanner 61 is movably connected to the frame 1 through the rod assembly 62. One end of the rod assembly 62 is connected to the frame 1 through the fixing block 63 to facilitate the angle adjustment of the barcode scanner 61.

[0062] Furthermore, the rod assembly 62 may include two rotatably connected rods, wherein the end of the rod away from the fixed block 63 is rotatably connected to a barcode scanner 61, thereby allowing the barcode scanner 61 connected to the rod assembly 62 to be adjusted in position relative to the mounting structure 2. For example, when one rod rotates relative to the other rod, the approximate position of the entire barcode scanner 61 relative to the mounting structure 2 can be adjusted. When the barcode scanner 61 is rotated around one rod, the angle of the barcode scanner 61 can be adjusted so that the barcode scanner 61 is aligned with the QR code on the worm gear 91 and scanned. Then, the barcode scanner 61 is adjusted to be aligned with the QR code on the worm 92. The barcode scanner 61 can record the model information of both the worm gear 91 and the worm 92.

[0063] In some embodiments, the pressing device 100 further includes an installation position and a pressing position, with a barcode scanning position located between the installation position and the pressing position. The installation structure 2 is adapted to install the worm gear 91 and the worm 92 at the installation position, and the pressing structure 7 is adapted to press the worm gear 91 and the worm 92 at the pressing position. The drive structure 5 drives the installation structure 2 to move from the installation position to the barcode scanning position and then to the pressing position.

[0064] Specifically, the drive structure 5 drives the mounting structure 2 to move between the scanning position and the pressing position. The pressing position, which is after the scanning position, first scans the approximately installed worm gear 91 and worm 92 to transmit the product model information of the worm gear 91 and worm 92 to the storage module for storage. When the mounting structure 2 moves to the pressing position, the pressing structure 7 presses the worm 92 to install the worm gear 91 and worm 92 into place.

[0065] Specifically, the press-fitting equipment 100 requires operation in three positions. When the worm gear 91 and worm 92 are not yet installed on the mounting structure 2, the mounting structure 2 is in the mounting position. By simply installing the worm gear 91 and worm 92 on the mounting structure 2 in the mounting position, the drive structure 5 drives the mounting structure 2 to move, so that the mounting structure 2 moves from the mounting position to the scanning position. The scanning structure 6 scans the QR codes on the worm gear 91 and worm 92 on the mounting structure 2 to record the specific product model information. If the specific product model is recorded, the scanned QR code information can be transmitted to the storage module for storage according to the actual situation.

[0066] Then, the drive structure 5 drives the mounting structure 2 to the pressing position. The pressing structure 7 presses the worm 92 and worm wheel 91 at the pressing position. The pressing structure 7 can also transmit the pressing information to the storage module for storage. The pressing information records the pressing information corresponding to the product model, such as pressing force and pressing displacement. That is, after the product is pressed, the pressing information of the product can be matched with the product model information obtained by scanning the corresponding QR code, which is convenient for later inspection or traceability of the product information of worm wheel 91 and worm 92. If the product has quality problems or other situations that require understanding the product information, the pressing procedure at that time can be traced to see if it meets the requirements, thereby facilitating the improvement of the pressing work in the future. After the pressing is completed and the worm wheel 91 and worm 92 are removed, the drive structure 5 can continue to drive the mounting structure 2 to the installation position, and the next set of worm wheel 92 and worm wheel 91 can be installed.

[0067] In some embodiments, the mounting structure 2 is slidably connected to the frame 1 via the first slide rail assembly 3, and the driving structure 5 includes a cylinder assembly adapted to extend and retract along the extension direction of the first slide rail assembly 3 to drive the mounting structure 2 to move between the mounting position, the barcode scanning position and the pressing position.

[0068] In practice, the cylinder assembly can extend or retract by moving the telescopic rod relative to the cylinder body. The cylinder assembly is connected to one side of the mounting structure 2, and the mounting structure 2 is slidably connected to the frame 1 through the first slide rail assembly 3. The cylinder assembly drives the mounting structure 2 to move, resulting in good stability.

[0069] Specifically, refer to Figure 3 As shown, a fixing plate 14 is fixedly connected to the frame 1. Two parallel first slide rails 31 are connected to the fixing plate 14. Each first slide rail 31 is provided with a first slider 32, which can slide relative to the first slide rail 31. A first tray 21 is fixedly connected to the two first sliders 32. A second tray 22 is detachably connected to the first tray 21. A third sleeve 23 is connected to the second tray 22. The diameter of the third sleeve 23 is larger than the diameter of the first sleeve 24, so that the first sleeve 24 is partially installed inside the third sleeve 23. At this time, the second tray 22 and the third sleeve 24 are connected to the first tray 24. 3 can be used as a whole to form the aforementioned support component 27. The mounting structure 2 consists of the second tray 22, the third sleeve 23, and the movable component 28 connected thereto. The support component 27 is connected to the first slider 32 via the first tray 21 and is slidably connected to the first slide rail 31. That is, the aforementioned through hole 244 passes through the third sleeve 23, the first tray 21, and the second tray 22, and the limiting part 141 can be set on the fixed plate 14, so that the bottom of the first sleeve 24 can pass through the through hole 244 and contact the limiting part 141 located on the fixed plate 14.

[0070] Furthermore, the second tray 22 is detachably connected to the first tray 21, which facilitates the replacement of the mounting structure 2. The appropriate mounting structure 2 can be replaced according to the actual situation. Different mounting structures 2 can support different worm gears 92 and worm wheels 91.

[0071] It should be noted that when installing the second tray 22 and the first tray 21, the second tray 22 and the first tray 21 can be positioned at different locations using two locating pins 222. Then, the second tray 22 and the first tray 21 can be connected at other locations using connectors 223, making it easy to connect the second tray 22 and the first tray 21. When disassembling the second tray 22 and the first tray 21, the connectors 223 are first removed, and then the second tray 22 is removed. Handles 224 are also provided on both sides of the second tray 22 to facilitate the operator's handling and disassembly when removing and installing the structure 2.

[0072] Furthermore, a bottom extension 231 is formed radially at the bottom of the third sleeve 23. Multiple positioning structures 221 are provided around the third sleeve 23. Each positioning structure 221 includes a positioning bolt 2212 and a positioning block 2211. The positioning block 2211 is connected to the second tray 22. The positioning bolt 2212 passes through the positioning block 2211 and one end presses against the bottom extension 231 of the third sleeve 23. The end of the positioning bolt 2212 away from the third sleeve 23 is tightened by an adjusting nut to adjust the positioning bolt 2212 to tighten or loosen the third sleeve 23. By setting the positioning structure 221, the stability of the third sleeve 23 is improved, thereby ensuring the stability of the movement of the movable component 28, and further ensuring the stability of the movement of the worm gear 91 and worm 92 on the movable component 28.

[0073] In some embodiments, the pressing device 100 further includes a limiting buffer block 4 located at both ends of the mounting structure 2 along the sliding direction of the first slide rail assembly 3, so as to limit the mounting structure 2 when it moves to the mounting position and the pressing position.

[0074] In practice, the limiting buffer block 4 is constructed as a hydraulic buffer. When the mounting structure 2 moves to the mounting position or the pressing position, the hydraulic buffers at both ends press and limit the mounting structure 2 respectively, preventing the mounting structure 2 from sliding out of the first slide rail 31. The hydraulic buffer is a device that uses the viscous damping effect generated by fluid flow to achieve the buffering function. By limiting the mounting structure 2 in the mounting position and the pressing position, the hydraulic buffer can not only prevent the mounting structure 2 from sliding out of the first slide rail 31, but also provide a certain buffer for the mounting structure 2, thereby improving the movement stability of the mounting structure 2.

[0075] In some embodiments, the frame 1 further includes a second slide rail assembly 52, which includes a second slide rail 521 and a second slider 522. The second slider 522 is slidably connected to the second slide rail 521. The cylinder assembly includes a first cylinder 55 and a second cylinder 56. One end of the first cylinder 55 is connected to the second slider 522 and the other end is fixedly connected to the frame 1. The second cylinder 56 is connected to the second slider 522 and the end away from the first cylinder 55 is connected to the mounting structure 2.

[0076] In practice, the second slide rail 521 is connected to the frame 1, and the second slider 522 is slidably connected to the second slide rail 521. The first cylinder 55 and the second cylinder 56 can both be connected to the second slider 522, and the first cylinder 55 and the second cylinder 56 extend and retract in opposite directions. The extension and retraction directions of the first cylinder 55 and the second cylinder 56 are the directions of movement of the mounting structure 2. When the volume of the second slider 522 is small, a connecting block 54 can be fixedly connected to the second slider 522, and the first cylinder 55 and the second cylinder 56 can both be connected to the connecting block 54, with the extension and retraction directions of the first cylinder 55 and the second cylinder 56 being opposite. In addition, one end of the telescopic rod of the second cylinder 56 is connected to the first tray 21 through the connecting plate 51, that is, the second cylinder 56 and the mounting structure 2 are connected through the connecting plate 51, and the cylinder body of the second cylinder 56 is also connected to the connecting block 54; similarly, the cylinder body of the first cylinder 55 is connected to the connecting block 54, and the end of the telescopic rod of the first cylinder 55 is connected to the frame 1 through the fixed end 53.

[0077] Reference Figure 11 As shown, at this time, the drive structure 5 drives the mounting structure 2 to move to the mounting position, that is, both the first cylinder 55 and the second cylinder 56 are in the extended state. Figure 12 The drive structure 5 drives the mounting structure 2 to the scanning position, that is, the second cylinder 56 retracts, while the first cylinder 55 remains extended. Figure 13 With both the first cylinder 55 and the second cylinder 56 in a retracted state, and since the fixed end 53 of the first cylinder 55 is fixedly connected to the frame 1, the connecting block 54 and the second slider 522 can move relative to the second slide rail 521, so that the mounting structure 2 moves to the press-fit position.

[0078] Therefore, by setting the drive structure 5 so that the first cylinder 55 and the second cylinder 56 extend in opposite directions, it is convenient to adjust the mounting structure 2 in three different positions and reduce the space occupied by the drive structure 5 in the frame 1 along the direction of movement of the mounting structure 2.

[0079] In some embodiments, the frame 1 includes a base 11 and a top plate 12, a press-fit structure 7 is mounted on the top plate 12, a mounting structure 2 is connected to the base 11, and the press-fit structure 7 is adapted to extend and retract along the top plate 12 to press downward onto the mounting structure 2.

[0080] Specifically, the base 11 can be used to connect the first slide rail assembly 3, the second slide rail assembly 52, the mounting structure 2, and the drive structure 5, etc., while the top plate 12 can be used to install the pressing structure 7, the scanning structure 6, etc. When the mounting structure 2 moves along the base 11, the scanning structure 6 scans the code downwards from the top plate 12, making it convenient to align with the upper end face of the worm wheel 91 located at the top of the mounting structure 2, and also convenient to align with the position located at the top of the worm 92. The upper end face of the worm wheel 91 and the top of the worm 92 are both pre-set with QR codes, thus facilitating the scanning structure 6 to accurately locate the scanning position. Similarly, the pressing structure 7 is located on the top plate 12. When the pressing structure 7 is opposite to the worm 92 installed on the movable assembly 28, it can easily contact or move away from the worm 92, saving space.

[0081] Furthermore, the base 11 and the top plate 12 are connected by multiple support columns 13, and each support column 13 has an external thread at its upper end and extends above the top plate 12. Each support column 13 has at least two nuts 121 at its upper end on the top plate 12. The nuts 121 fasten the support column 13 to the top plate 12, improving the reliability of the top plate 12. Fastening the support column 13 to the top plate 12 with the nuts 121 makes it easy to disassemble the top plate 12 and the barcode scanning structure 6 and the press-fitting structure 7 installed on the top plate 12.

[0082] Specifically, the press structure 7 is equipped with a press 71 and a head 72. The head 72 is retractable relative to the press 71 and contacts and presses against the worm gear 92. The head 72 can be quickly changed, and the quick change is carried out by a quick change wrench 8. Different sizes of head 72 can be installed to meet the needs of different products.
