[0035] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0036] Combination Figures 1 to 13 As shown in the embodiments of this disclosure, the installation device for a steering gear includes a fixing device 10 and a moving device 20. The fixing device 10 includes a support assembly and a locking assembly. The support assembly is used to vertically install the steering gear 80, and the locking assembly is used to laterally fix both ends of the steering gear 80. The moving device 20 includes a sliding device 201 and a positioning device 202 for installing a gear shaft 90. The positioning device 202 slides along the sliding device 201 to adjust the relative position of the gear shaft 90 and the steering gear 80. The positions of the support assembly and the locking assembly are adjustable so that the gear shaft 90 can be inserted into a preset position of the steering gear 80.

[0037] The installation equipment for the steering gear provided in this embodiment of the present disclosure achieves precise vertical and lateral positioning of the steering gear 80 through adjustable support components and locking components; the sliding adjustment function of the moving device 20 enables the gear shaft 90 to be quickly aligned with the steering gear 80, improving assembly efficiency; the compact design of the overall structure reduces redundant parts, lowers equipment costs and floor space; the coordinated work of the fixed device 10 and the moving device 20 reduces adjustment steps in the assembly process and shortens the single-station operation time.

[0038] The vertical adjustability of the support components ensures the precise installation of the steering gear 80 in the height direction, solving the problem that traditional equipment cannot adapt to the height differences of steering gears 80 of different specifications; the lateral adjustability of the locking components enables stable clamping of both ends of the steering gear 80, eliminating the risk of lateral displacement and improving the reliability of fixation; the cooperation between the sliding device 201 and the positioning device 202 allows the gear shaft 90 to move along a preset trajectory, achieving quick alignment with the shaft hole of the steering gear 80, avoiding alignment errors caused by manual intervention.

[0039] The adjustable design of the support and locking components allows the equipment to be adapted to different sizes and specifications of steering gears 80, eliminating the need for custom tooling for each model and significantly reducing changeover costs.

[0040] Optionally, the support assembly includes: a support platform 101, which is provided with multiple positioning modules 102 for mounting and fixing the steering gear 80; a lifting cylinder 103, which is located below the support platform 101 and is used to drive the support platform 101 to move up and down; and a fixing frame 104, which is located below the support platform 101 and connected to the lifting cylinder 103 to support and fix the lifting cylinder 103.

[0041] The lifting cylinder 103 drives the support platform 101 to rise and fall vertically. The lifting cylinder 103 quickly drives the support platform 101 to the assembly height, shortening the debugging time. The fixed frame 104 provides rigid support for the lifting cylinder 103, ensuring that the steering gear 80 rises and falls smoothly and avoiding shaking.

[0042] Optionally, the support assembly further includes: a guide shaft 105, one end of which is connected to the support platform 101 and the other end of which is connected to the fixed frame 104; its axial direction is parallel to the axial direction of the lifting cylinder 103; wherein, multiple guide shafts 105 are evenly distributed around the lifting cylinder 103.

[0043] The guide shaft 105 restricts the lateral displacement of the support platform 101, improving the straightness and positioning accuracy of the lifting motion; in addition, the evenly distributed multiple guide shafts 105 ensure that the support platform 101 is subjected to balanced forces, enhancing structural stability.

[0044] Optionally, the guide shaft 105 is a telescopic structure to cooperate with the lifting cylinder 103 to drive the support platform 101 to move up and down.

[0045] The telescopic structure of the guide shaft 105 adapts to different heights of the steering gear 80, allowing for stroke adjustment without hardware replacement, thus improving the equipment's compatibility with multiple steering gear 80 models.

[0046] Optionally, the ends of two adjacent guide shafts 105 are connected by a connector 106 to further limit the degree of freedom of the guide shafts 105 and improve the guiding accuracy of the guide shafts 105.

[0047] The connector 106 connects two adjacent guide shafts 105, enhancing the overall rigidity of the guide shaft 105, reducing the sway of a single guide shaft 105, further improving the guiding accuracy, and ensuring the stability of the lifting trajectory of the support platform 101.

[0048] Optionally, the fixing frame 104 includes a frame body 1041 and a mounting plate 1042. The mounting plate 1042 is fixedly connected to the frame body 1041, and the surface of the mounting plate 1042 is perpendicular to the extension and retraction direction of the telescopic rod of the lifting cylinder 103.

[0049] The vertical layout optimizes the direction of force on the cylinder, avoiding eccentric loads; the mounting plate 1042 provides a standardized installation interface, facilitating equipment maintenance and component replacement.

[0050] Optionally, the cylinder body of the lifting cylinder 103 and the bushing of the guide shaft 105 can both be detachably connected to the mounting plate 1042. The cylinder body of the lifting cylinder 103 and the bushing of the guide shaft 105 are detachably connected to the mounting plate 1042 by bolts. The modular design supports quick disassembly and maintenance, shortens downtime, and improves equipment maintenance efficiency.

[0051] Optionally, the shaft portion of the guide shaft 105 and the telescopic rod of the lifting cylinder 103 pass through the mounting plate 1042 to further define the extension and retraction direction of the guide shaft 105 and the telescopic rod of the lifting cylinder 103.

[0052] Optionally, the support assembly further includes multiple support modules 107, which are disposed on the support platform 101 and abut against the crossbeam of the frame 30 at their top to limit and fix the longitudinal displacement of the support platform 101. For example, the multiple support modules 107 are evenly distributed or symmetrically arranged on the support platform 101 to further improve the stability of the support platform 101.

[0053] Optionally, the support module 107 includes: a support block 1071, fixedly mounted on the support platform 101, and having a hole structure at the top; a positioning pin 1072, with its bottom inserted into the hole structure at the top of the support block 1071; and a support shaft 1073, with a hole structure at its end, which is sleeved on the top of the positioning pin 1072 and engaged with the positioning pin 1072; wherein the top of the support shaft 1073 is fixedly connected to the crossbeam of the frame 30.

[0054] The support module 107 is engaged with the positioning pin 1072 at the top of the support block 1071 and the hole structure at the bottom of the support shaft 1073 to fix the position of the support platform 101. The mechanical engagement achieves precise positioning of the support platform 101 at the preset position, avoiding the risk of misjudgment by relying on sensors and ensuring that the steering gear 80 is quickly positioned.

[0055] The top of the support shaft 1073 is fixed to the crossbeam of the frame 30, and the bottom is fitted with the locating pin 1072. The load of the support platform 101 is directly transferred to the crossbeam of the frame 30, which enhances the structural rigidity and ensures the stability of the mounting reference of the steering gear 80.

[0056] For example, when the lifting cylinder 103 is activated, its telescopic rod drives the support platform 101 to move upward until the positioning pin 1072 is inserted and engaged with the bottom of the support shaft 1073, indicating that the support platform 101 has reached the preset position. In this way, the steering gear 80 is quickly positioned, shortening the debugging time.

[0057] Optionally, the positioning module 102 includes: a fixing block 1021 mounted on the support platform 101; an adjusting block 1022 disposed on the fixing block 1021; and a clamping block 1023 disposed on the support platform 101, with its end corresponding to the adjusting block 1022, to clamp and fix the edge of the steering gear 80. A spring 1025 is provided between the clamping block 1023 and the fixing block 1021. A limiting shaft 1024 passes through the clamping block 1023 and the spring 1025, with its end inserted into and fixed to the fixing block 1021. The limiting shaft 1024 is used to limit the displacement of the spring 1025. A locking nut 1026 is threadedly connected to the end of the limiting shaft 1024. By adjusting the locking nut 1026, the compression of the spring 1025 is adjusted, thereby adjusting the distance between the clamping block 1023 and the adjusting block 1022.

[0058] The positioning module 102 connects the clamping block 1023 and the fixing block 1021 via a spring 1025, and the compression of the spring 1025 is adjusted by the locking nut 1026. The elastic clamping adapts to the edge thickness difference of the steering gear 80, and the adjustable clamping force prevents part deformation, improving the equipment's adaptability to different models of steering gear 80.

[0059] Optionally, the locking assembly includes: a first locking module 108, including a push rod 1081 that can reciprocate axially for abutting against the first end of the steering gear 80; and a second locking module 109, including a longitudinally arranged limiting block 1091 and a positioning block 1092, the limiting block 1091 and the positioning block 1092 clamping the second end of the steering gear 80 for fixation; wherein the limiting block 1091 can move longitudinally to adjust the distance between itself and the positioning block 1092.

[0060] The axial movement of the push rod 1081 achieves rigid contact with the first end of the steering gear 80, restricting the degree of freedom in the X-axis direction and eliminating the risk of axial movement; the cooperation between the limit block 1091 and the positioning block 1092 forms a clamping force on the second end of the steering gear 80, restricting the degree of freedom in the X and Y axes and preventing lateral displacement; the bidirectional constraint mechanism enables the steering gear 80 to maintain a stable posture during assembly.

[0061] The axial travel of the push rod 1081 is adjustable, further enhancing compatibility with variations in the length of the steering gear 80 and enabling "one mold for multiple fittings". The longitudinal movement function of the limit block 1091 can dynamically adjust the distance between it and the positioning block 1092, automatically adapting to steering gears 80 of different widths without the need to change the fixture.

[0062] This embodiment avoids stress concentration caused by traditional unidirectional fixing through a combination of rigid contact and elastic clamping, reducing the risk of component deformation. Furthermore, the adjustable clamping force ensures protection for thin-walled or vulnerable steering gear 80 while maintaining sufficient fixing strength to prevent loosening.

[0063] Optionally, the first locking module 108 further includes an ejector cylinder 1082, whose telescopic rod is connected to the push rod 1081 via a connecting plate 1083, so as to drive the push rod 1081 to extend and retract along its axial direction; wherein, the telescopic rod of the ejector cylinder 1082 and the push rod 1081 are arranged in opposite directions; when the telescopic rod of the ejector cylinder 1082 extends, the push rod 1081 retracts; when the telescopic rod of the ejector cylinder 1082 retracts, the push rod 1081 extends and abuts against the first end of the steering gear 80 for fixation. In this way, interference with other mounting structures of the steering gear 80 can be avoided when the telescopic rod of the ejector cylinder 1082 and the push rod 1081 extend in the same direction.

[0064] The first locking module 108 drives the push rod 1081 through the push cylinder 1082 to abut against the first end of the steering gear 80 axially. The push rod 1081 quickly extends and abuts against the steering gear 80, cooperating with the second locking module 109 to achieve bidirectional fixation and improve the reliability of the steering gear 80 positioning.

[0065] The telescopic rod of the ejector cylinder 1082 is arranged in opposite directions to the ejector rod 1081 and connected by a connecting plate 1083. Reverse drive avoids interference between the cylinder and other structures of the steering gear 80, and eliminates the extra axial space required when the ejector cylinder 1082 and ejector rod 1081 are arranged in the same direction, thus shortening the overall length of the equipment. In multi-station collaborative operation scenarios, reverse drive can reduce the risk of motion interference between adjacent devices and improve the overall operating efficiency of the production line.

[0066] In addition, the connecting plate 1083 directly converts the cylinder thrust into the extension force of the push rod 1081, avoiding energy loss in the intermediate transmission links.

[0067] Optionally, the ejector cylinder 1082 is mounted on the first column assembly 301 of the frame 30. This helps to improve the stability and reliability of the ejector cylinder 1082 during operation.

[0068] Optionally, the connecting plate 1083 for connecting the telescopic rod of the ejector cylinder 1082 and the ejector rod 1081 is slidably connected to the column of the first column assembly 301 to further improve the stability of the telescopic movement of the ejector rod 1081.

[0069] The connecting plate 1083, which connects the telescopic rod of the ejector cylinder 1082 and the ejector rod 1081, is slidably connected to the column. The sliding connection improves the smoothness of the ejector rod 1081's movement, reduces swaying, and ensures that the ejector rod 1081 is perpendicularly abutted against the end face of the steering gear 80.

[0070] Optionally, the second locking module 109 further includes a vertical cylinder 1093, mounted on the column of the second column assembly 302 of the frame 30, whose telescopic rod is connected to the limiting block 1091 to drive the limiting block 1091 to move longitudinally, thereby adjusting the distance between the limiting block 1091 and the positioning block 1092. This not only allows for the adaptation to different models of steering gear 80, but also ensures a secure clamping effect on the second end of the steering gear 80.

[0071] The second locking module 109 drives the limiting block 1091 to move longitudinally via the vertical cylinder 1093, clamping the second end of the steering gear 80 with the positioning block 1092. The adjustable clamping distance adapts to steering gears 80 of different widths, avoiding the need to replace special fixtures and improving equipment changeover efficiency.

[0072] In addition, the linear drive characteristic of the vertical cylinder 1093 ensures that the movement trajectory of the limit block 1091 is strictly parallel to that of the positioning block 1092, achieving uniform clamping of the second end of the steering gear 80. The vertical layout makes the direction of the cylinder thrust perpendicular to the direction of gravity of the steering gear 80, avoiding interference of gravity on the clamping force and improving positioning stability.

[0073] Optionally, the positioning block 1092 is mounted on the column of the second column assembly 302 of the frame 30. This helps to ensure the stability and reliability of the positioning block 1092 and the limiting block 1091 during the clamping process.

[0074] Optionally, it also includes: a frame 30, including a crossbeam assembly 303 and a first column assembly 301 and a second column assembly 302 disposed opposite to each other, the crossbeam assembly 303 being disposed on top of the first column assembly 301 and facing the second column assembly 302; wherein, the support assembly is located between the first column assembly 301 and the second column assembly 302, and the moving device 20 is connected to the crossbeam assembly 303 through a cantilever beam 304.

[0075] The modular frame 30 has a compact layout, with all components working together to improve the alignment efficiency of the gear shaft 90 and the steering gear 80, and reduce the equipment's footprint.

[0076] The sliding device 201 of the moving device 20 is suspended below the crossbeam assembly 303 via the cantilever beam 304. The cantilever beam 304 can move laterally, and in conjunction with the steering gear 80 provided in the column assembly, it enables the gear shaft 90 to be flexibly aligned in multiple dimensions to adapt to different assembly angle requirements.

[0077] Optionally, the sliding device 201 includes: a slide cylinder 2011 connected to the cantilever beam 304; and an auxiliary slide rail 2012 connected to the cantilever beam 304 and arranged parallel to the slide cylinder 2011; wherein both the slide cylinder 2011 and the auxiliary slide rail 2012 are slidably connected to the positioning device 202. When the slide cylinder 2011 is not working, the positioning device 202 can be slid along the auxiliary slide rail 2012 to the steering gear 80 by a manual pusher, so that the gear shaft 90 is installed and connected to the steering gear 80.

[0078] The slide cylinder 2011 enables the automatic drive positioning device 202 to move precisely, while the auxiliary slide rail 2012 supports manual emergency operation, improving the equipment's adaptability to different working conditions.

[0079] Optionally, the positioning device 202 includes: a reference block 2021, which is slidably connected to the slide cylinder 2011 and the auxiliary cylinder via a sliding assembly 2013; a rotary cylinder 2022, which is disposed on the reference block 2021 and rotatably connected to the reference block 2021 via a connecting shaft; a compensation unit 2023, which is disposed on both sides of the reference block 2021 and connected to the connecting shaft, so as to rotate under the drive of the rotary cylinder 2022; and a positioning shaft 2024, which is connected to the compensation unit 2023 and has a limiting hole constructed along the axial direction, the limiting hole being used to insert the gear shaft 90.

[0080] The positioning device 202 is connected to the slide cylinder 2011 and the auxiliary slide rail 2012 via a sliding component 2013 connected to the reference block 2021, thereby achieving linear movement in the X-axis direction. The sliding component 2013 ensures smooth movement of the positioning device 202, and the reference block 2021 provides a unified installation interface for easy and quick replacement of components of different specifications.

[0081] Rotary cylinder 2022 drives positioning shaft 2024 to rotate around the Z-axis, solving the problem of angle adjustment in traditional fixed positioning methods. Rotary cylinder 2022 drives compensation unit 2023 and positioning shaft 2024 to rotate via a connecting shaft; compensation unit 2023 absorbs planar errors. Rotary cylinder 2022 precisely controls the rotation angle of gear shaft 90, and compensation unit 2023 dynamically absorbs errors, solving the jamming problem of rigid installation and improving assembly accuracy. The linkage between rotary cylinder 2022 and compensation unit 2023 allows gear shaft 90 to dynamically adjust its angle during insertion, adapting to the meshing requirements of the helical gear within steering gear 80.

[0082] The clearance fit between the limiting hole and the gear shaft 90 ensures quick insertion while restricting circumferential freedom to prevent slippage during rotation.

[0083] It should be noted that the compensation unit 2023 is an existing component, and its working principle will not be described in this article. The elastic structure of the compensation unit 2023 can absorb a certain amount of planar deviation, avoiding assembly interference caused by part machining errors.

[0084] Optionally, the positioning device 202 further includes an encoder 2026, disposed at the end of the connecting shaft and fixedly connected to it, for detecting the rotation angle of the connecting shaft and sending a signal to the compensation unit 2023, so that the compensation unit 2023 compensates for the displacement of the gear shaft 90. The compensation unit 2023 dynamically adjusts the position of the gear shaft 90 according to the feedback signal, eliminating angular deviations caused by transmission backlash and elastic deformation. For example, the compensation unit 2023 can realize X / Y axis displacement compensation and automatically correct the axis deviation between the gear shaft 90 and the steering gear 80.

[0085] For example, the encoder 2026 continuously monitors the rotation process and automatically triggers an alarm and stops when it detects a sudden change in angle caused by abnormal resistance.

[0086] Optionally, the inner annular surface of the end of the limiting hole is constructed with a planar structure, and the end of the gear shaft 90 matches it to limit the circumferential degree of freedom of the positioning shaft 2024 and the gear shaft 90.

[0087] The inner annular surface of the locating shaft 2024's limiting hole end has a planar structure that matches the flat end of the gear shaft 90. The flat anti-rotation design replaces the traditional keyway, simplifies the assembly and alignment process, ensures accurate circumferential positioning of the gear shaft 90, and avoids rotational offset.

[0088] Optionally, it also includes: a handle 40, provided on the sliding assembly 2013, for manually pushing the positioning device 202 to move, thereby assembling the steering gear 80 and the gear shaft 90.

[0089] When the slide cylinder 2011 is not in operation, the positioning device 202 can be moved along the auxiliary slide rail 2012 by manually pushing the handle 40. In manual mode, assembly can continue even in the event of an automatic system failure, avoiding production interruptions and ensuring production line continuity. Additionally, the handle 40 provides manual fine-tuning functionality, facilitating equipment debugging and emergency operation, thus improving ease of use and reliability.

[0090] Optionally, it also includes: a rotary table 305, which is mounted on the crossbeam assembly 303 of the frame 30 and connected to the cantilever beam 304; the cantilever beam 304 drives the moving device 20 to rotate around the axis of the rotary table 305.

[0091] The cantilever beam 304 is mounted on the crossbeam assembly 303 via a rotary table 305 and can rotate around the axis of the rotary table 305. The rotary table 305 supports the rotation of the cantilever beam 304, enabling multi-angle assembly of the gear shaft at 90 degrees and expanding the applicability of the equipment to different models of steering gears 80.

[0092] Optionally, it also includes a locking cylinder 306, connected to the cantilever beam 304 and vertically arranged, with its telescopic rod facing the crossbeam assembly 303. When the cantilever beam 304 rotates to a set position, the telescopic rod extends and abuts against the crossbeam assembly 303, thereby limiting the rotation of the cantilever beam 304. The locking cylinder 306 ensures that the cantilever beam 304 is fixed at a set angle, preventing angular deviation during assembly and ensuring the accuracy of multi-angle assembly.

[0093] Optionally, it also includes a barcode reader 50, mounted on the cantilever beam 304 or a related component fixedly connected to the cantilever beam 304, for reading the QR code on the gear shaft 90 and sending a signal to the controller, so that the controller controls the actions of the lifting cylinder 103, the ejection cylinder 1082, the vertical cylinder 1093, the sliding cylinder 2011, and the rotary cylinder 2022. The barcode reader 50 reads the QR code on the gear shaft 90 and sends a signal to the controller to control the actions of each cylinder. It automatically identifies the information on the gear shaft 90 and triggers the assembly process, reducing manual intervention and improving automation and assembly efficiency.

[0094] For example, the barcode reader 50 reads the QR code on the gear shaft 90, triggering the lifting cylinder 103, the ejection cylinder 1082, and the vertical cylinder 1093 to fix the steering gear 80 and drive the support platform 101 to a set position, waiting for the steering gear 80 to be assembled with the gear shaft 90. Alternatively, the slide cylinder 2011 can be triggered to drive the positioning device 202, on which the gear shaft 90 is mounted, to move towards the position of the steering gear 80.

[0095] Optionally, it also includes: a first detection sensor, located below the crossbeam assembly 303 and facing the support platform 101. When the support platform 101 is detected to have reached a set position, the ejector cylinder 1082 and the vertical cylinder 1093 are triggered, causing the push rod 1081 to extend and press against the first end of the steering gear 80, and the limiting block 1091 to move upward and clamp and fix the second end of the steering gear 80 with the positioning block 1092.

[0096] The slide cylinder 2011 actuates, driving the positioning device 202 to move towards the position of the steering gear 80. The adjusting valve on the slide cylinder 2011 can adjust the speed of movement. After the positioning device 202 reaches the set position, the rotary cylinder 2022 indirectly drives the gear shaft 90 to rotate. The encoder 2026 detects the rotation angle and triggers the compensation unit 2023 to dynamically compensate for the offset angle of the gear shaft 90. Finally, the gear shaft 90 is assembled into the set position of the steering gear 80.

[0097] Optionally, it also includes: a second detection sensor 70, disposed on the cantilever beam 304 or a related component fixedly connected to the cantilever beam 304, for detecting the depth of the gear shaft 90 inserted into the steering gear 80. This determines the assembly status of the gear shaft 90 and the steering gear 80, i.e., whether they are properly assembled.

[0098] The first detection sensor detects the position of the support platform 101, and the second detection sensor 70 detects the insertion depth of the gear shaft 90. Real-time feedback of assembly position and depth data ensures proper installation, avoids omissions or incomplete assembly, and improves product assembly quality.
