[0035] It should be noted that, without conflict, the embodiments in the embodiments of the present disclosure and the features in the embodiments can be combined with each other.

[0036] Combined Figures 1 to 13 As shown, the installation device for a steering gear provided by the embodiments of the present disclosure 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 horizontally fix both ends of the steering gear 80; the moving device 20 includes a sliding device 201 and a positioning device 202 for installing the gear shaft 90. The positioning device 202 slides along the sliding device 201 to adjust the relative position between the gear shaft 90 and the steering gear 80; wherein, the positions of the support assembly and the locking assembly are both adjustable so that the gear shaft 90 can be inserted into a preset position of the steering gear 80.

[0037] By using the installation device for a steering gear provided by the embodiments of the present disclosure, precise positioning of the steering gear 80 in the vertical and horizontal directions is achieved through the adjustable support assembly and locking assembly; the sliding adjustment function of the moving device 20 enables the gear shaft 90 and the steering gear 80 to be quickly aligned, improving the assembly efficiency; the overall compact structure design reduces redundant components, lowering the equipment cost and floor space; the coordinated work of the fixing device 10 and the moving device 20 reduces the adjustment steps in the assembly process and shortens the single-station operation time.

[0038] The vertical adjustability of the support assembly 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 assembly realizes stable clamping of both ends of the steering gear 80, eliminates the risk of lateral deviation, and improves the reliability of fixation; the cooperation between the sliding device 201 and the positioning device 202 enables the gear shaft 90 to move along a preset trajectory, achieving rapid shaft hole alignment with the steering gear 80, and avoiding alignment errors caused by manual intervention.

[0039] The adjustable design of the support assembly and the locking assembly enables the equipment to adapt to steering gears 80 of different sizes and specifications, eliminating the need to customize special tooling for each model, significantly reducing changeover costs.

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

[0041] The lifting cylinder 103 drives the support platform 101 to lift 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 to ensure that the steering gear 80 is lifted and lowered smoothly to avoid shaking.

[0042] Optionally, the support assembly also includes: a guide shaft 105, one end of which is connected to the support platform 101, and the other end is connected to the fixed frame 104; its axial direction is arranged 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 limits the lateral deviation of the support platform 101, thereby improving the straightness and positioning accuracy of the lifting movement; in addition, the evenly distributed multiple guide shafts 105 balance the force on the support platform 101, thereby enhancing the 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 is adaptive to steering gears 80 of different heights, and the stroke can be adjusted without replacing hardware, thereby improving the compatibility of the equipment with steering gears 80 of various models.

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

[0047] The connecting member 106 connects two adjacent guide shafts 105, enhancing the overall rigidity of the guide shafts 105, reducing the swing of a single guide shaft 105, further improving the guiding accuracy, and ensuring the stability of the lifting trajectory of the support table 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 plate surface of the mounting plate 1042 is perpendicular to the telescopic direction of the telescopic rod of the lifting cylinder 103.

[0049] By optimizing the force direction of the cylinder through vertical layout, eccentric load is avoided; the mounting plate 1042 provides a standardized mounting interface, facilitating equipment maintenance and component replacement.

[0050] Optionally, both the cylinder body of the lifting cylinder 103 and the bushing of the guide shaft 105 are 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 the downtime, and improves the 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 telescopic direction of the guide shaft 105 and the telescopic rod of the lifting cylinder 103.

[0052] Optionally, the support assembly further includes a plurality of support modules 107. The support modules 107 are arranged on the support table 101, and the top abuts against the cross beam of the frame 30 to define and fix the longitudinal displacement of the support table 101. Exemplarily, the plurality of support modules 107 are evenly distributed or symmetrically arranged on the support table 101 to further improve the stability of the support table 101.

[0053] Optionally, the support module 107 includes: a support block 1071, fixedly arranged on the support table 101, and having a hole structure at the top; a positioning pin 1072, the bottom of which is inserted into the hole structure at the top of the support block 1071; a support shaft 1073, having a hole structure at the end, and the support shaft 1073 is sleeved on the top of the positioning pin 1072 through the hole structure and is fixedly connected to the positioning pin 1072 by clamping; wherein, the top of the support shaft 1073 is fixedly connected to the cross beam of the frame 30.

[0054] The support module 107 is clamped to the support shaft 1073 through the positioning pin 1072 at the top of the support block 1071 to fix the position of the support table 101. The mechanical clamping realizes the accurate positioning of the preset position of the support table 101, avoids the misjudgment risk relying on sensors, and ensures the quick positioning of the steering gear 80.

[0055] The top of the support shaft 1073 is fixed to the crossbeam of the frame 30, and the bottom is sleeved on the positioning pin 1072. The load of the support table 101 is directly transmitted to the crossbeam of the frame 30, enhancing the structural rigidity and ensuring the stability of the installation reference of the steering gear 80.

[0056] Exemplarily, when the lifting cylinder 103 operates, its telescopic rod drives the support table 101 to move upward until the positioning pin 1072 is inserted and clamped at the bottom of the support shaft 1073, indicating that the support table 101 reaches the preset position. In this way, the steering gear 80 can be quickly positioned, shortening the debugging time.

[0057] Optionally, the positioning module 102 includes: a fixed block 1021 installed on the support table 101; an adjustment block 1022 provided on the fixed block 1021, and a pressing block 1023 provided on the support table 101, with the end corresponding to the adjustment block 1022 to clamp and fix the edge of the steering gear 80; wherein, a spring 1025 is provided between the pressing block 1023 and the fixed block 1021, and a limiting shaft 1024 passes through the pressing block 1023 and the spring 1025, with the end inserted and fixed in the fixed block 1021, and 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, and by adjusting the locking nut 1026, the compression amount of the spring 1025 is adjusted, thereby adjusting the distance between the pressing block 1023 and the adjustment block 1022.

[0058] The positioning module 102 connects the pressing block 1023 and the fixed block 1021 through the spring 1025, and adjusts the compression amount of the spring 1025 through the locking nut 1026. The elastic clamping adapts to the thickness difference of the edge of the steering gear 80, and the adjustable clamping force avoids part deformation, improving the adaptability of the equipment to different models of steering gears 80.

[0059] Optionally, the locking assembly includes: a first locking module 108 including a push rod 1081 that can reciprocate axially, used to abut against the first end of the steering gear 80; a second locking module 109 including a longitudinally arranged limiting block 1091 and a positioning block 1092, and the limiting block 1091 and the positioning block 1092 clamp the second end of the steering gear 80 to fix it; wherein, the limiting block 1091 can move longitudinally to adjust the distance from the positioning block 1092.

[0060] The axial movement of the push rod 1081 realizes the rigid abutment against the first end of the steering gear 80, restricting the freedom degree in the X-axis direction and eliminating the risk of axial movement; the cooperation between the limiting block 1091 and the positioning block 1092 forms a clamping force on the second end of the steering gear 80, restricting the freedom degrees in the X and Y axis directions and preventing lateral offset; the two-way constraint mechanism keeps the steering gear 80 in a stable posture during the assembly process.

[0061] The axial stroke of the ejector rod 1081 is adjustable, further enhancing the compatibility with the length differences of the steering gear 80 and realizing "one mold for multiple matches". The longitudinal movement function of the limit block 1091 can dynamically adjust the distance from the positioning block 1092 and automatically adapt to steering gears 80 of different width dimensions without replacing the fixture.

[0062] In this embodiment, the combined design of rigid abutment and elastic clamping avoids stress concentration caused by traditional unidirectional fixation and reduces the risk of part deformation. Additionally, the adjustable clamping force ensures the protection of thin-walled or vulnerable steering gears 80 while ensuring 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 ejector rod 1081 through a connecting plate 1083 to drive the ejector rod 1081 to perform telescopic movement along its axis; wherein, the telescopic rod of the ejector cylinder 1082 is arranged in the opposite direction to the ejector rod 1081; when the telescopic rod of the ejector cylinder 1082 extends, the ejector rod 1081 retracts; when the telescopic rod of the ejector cylinder 1082 retracts, the ejector rod 1081 extends and abuts against the first end of the steering gear 80 for fixation. In this way, it can avoid interfering with other mounting structures of the steering gear 80 when the telescopic rod of the ejector cylinder 1082 and the ejector rod 1081 extend in the same direction.

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

[0065] The telescopic rod of the ejector cylinder 1082 is arranged in the opposite direction to the ejector rod 1081 and is connected through the connecting plate 1083. The reverse drive avoids interference between the cylinder and other structures of the steering gear 80, avoids the additional axial space required when the ejector cylinder 1082 and the ejector rod 1081 are arranged in the same direction, and shortens the overall length of the equipment. In the scenario of multi-station collaborative operation, the reverse drive can reduce the risk of movement interference between adjacent equipment and improve the overall operation efficiency of the production line.

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

[0067] Optionally, the ejector cylinder 1082 is installed on the first column assembly 301 of the frame 30. In this way, it helps to improve the working stability and reliability of the ejector cylinder 1082.

[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 that connects the telescopic rod of the ejection cylinder 1082 and the ejector rod 1081 is slidably connected to the column. The sliding connection improves the movement smoothness of the ejector rod 1081, reduces shaking, and ensures that the ejector rod 1081 is vertically abutted against the end face of the steering gear 80.

[0070] Optionally, the second locking module 109 further includes: a vertical cylinder 1093, which is arranged on the column of the second column assembly 302 of the frame 30, and its telescopic rod is connected to the limiting block 1091 to drive the limiting block 1091 to move longitudinally, so as to adjust the distance between the limiting block 1091 and the positioning block 1092. In this way, not only can different models of steering gears 80 be adapted, but also the clamping effect on the second end of the steering gear 80 can be ensured.

[0071] The second locking module 109 drives the limiting block 1091 to move longitudinally through the vertical cylinder 1093, and clamps 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, avoids replacing special fixtures, and improves the equipment changeover efficiency.

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

[0073] Optionally, the positioning block 1092 is installed on the column of the second column assembly 302 of the frame 30. In this way, it helps to ensure the stability and reliability during the clamping process between the positioning block 1092 and the limiting block 1091.

[0074] Optionally, it further includes: a frame 30, which includes a cross beam assembly 303 and relatively arranged first column assemblies 301 and second column assemblies 302. The cross beam assembly 303 is arranged on the top of the first column assembly 301 and faces the second column assembly 302; wherein, the support device is located between the first column assembly 301 and the second column assembly 302, and the moving device 20 is connected to the cross beam assembly 303 through a cantilever beam 304.

[0075] The modular frame 30 has a compact layout, and each component cooperates to improve the centering efficiency of the gear shaft 90 and the steering gear 80, and reduces the floor area of the equipment.

[0076] The sliding device 201 of the moving device 20 is suspended below the cross beam assembly 303 through the cantilever beam 304. The cantilever beam 304 can move horizontally, cooperate with the steering gear 80 arranged in the column assembly, realize flexible centering of the gear shaft 90 in multiple dimensions, and adapt to different assembly angle requirements.

[0077] Optionally, the sliding device 201 includes: a sliding table cylinder 2011 connected to the cantilever beam 304; an auxiliary slide rail 2012 connected to the cantilever beam 304 and arranged in parallel with the sliding table cylinder 2011; wherein both the sliding table cylinder 2011 and the auxiliary slide rail 2012 are slidably connected to the positioning device 202. When the sliding table 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 sliding table cylinder 2011 realizes the automatic driving of the positioning device 202 to move precisely, and the auxiliary slide rail 2012 supports manual emergency operations, improving the adaptability of the equipment working conditions.

[0079] Optionally, the positioning device 202 includes: a reference block 2021 slidably connected to the sliding table cylinder 2011 and the auxiliary cylinder through a sliding component 2013; a rotary cylinder 2022 arranged on the reference block 2021 and rotatably connected to the reference block 2021 through a connecting shaft; a compensation unit 2023 and the rotary cylinder 2022 are respectively arranged on both sides of the reference block 2021 and connected to the connecting shaft to rotate under the drive of the rotary cylinder 2022; a positioning shaft 2024 connected to the compensation unit 2023 and having a limiting hole formed along the axial direction, and the limiting hole is used for inserting the gear shaft 90.

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

[0081] The rotary cylinder 2022 drives the positioning shaft 2024 to rotate around the Z-axis, solving the problem that the traditional fixed positioning method cannot adjust the angle. The rotary cylinder 2022 drives the compensation unit 2023 and the positioning shaft 2024 to rotate through the connecting shaft, and the compensation unit 2023 absorbs the planar error. The rotary cylinder 2022 precisely controls the rotation angle of the gear shaft 90, and the compensation unit 2023 dynamically absorbs the error, solving the jamming problem of rigid installation and improving the assembly accuracy. The linkage between the rotary cylinder 2022 and the compensation unit 2023 enables the gear shaft 90 to dynamically adjust the angle during the insertion process to adapt to the meshing requirements of the spiral gear in the steering gear 80.

[0082] The clearance fit between the limiting hole and the gear shaft 90 ensures quick insertion and at the same time restricts the circumferential degree of freedom to prevent slipping 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 and avoid assembly interference caused by part processing errors.

[0084] Optionally, the positioning device 202 further includes: an encoder 2026, provided at the end of the connecting shaft and fixedly connected to the connecting shaft, 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 to eliminate the angular deviation caused by transmission clearance and elastic deformation. Exemplarily, the compensation unit 2023 can achieve X / Y axis displacement compensation and automatically correct the axial center deviation between the gear shaft 90 and the steering gear 80.

[0085] Exemplarily, the encoder 2026 continuously monitors the rotation process and automatically triggers an alarm and stops when an angular mutation caused by abnormal resistance is detected.

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

[0087] The inner ring surface at the end of the limiting hole of the positioning shaft 2024 is provided with a planar structure, which matches the flat position at the end of the gear shaft 90. The anti-rotation design of the flat position replaces the traditional keyway, simplifies the assembly alignment process, ensures accurate circumferential positioning of the gear shaft 90, and avoids rotational offset.

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

[0089] When the slide cylinder 2011 is not working, the positioning device 202 is moved by manually pushing the handle 40 along the auxiliary slide rail 2012. The manual mode can continue to complete the assembly when the automatic system fails, avoiding production interruption and ensuring the continuity of the production line. In addition, the handle 40 provides a manual fine-tuning function, which is convenient for equipment debugging and emergency operations, improving the usability and reliability.

[0090] Optionally, it further includes: a rotary table 305, provided 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 installed on the crossbeam assembly 303 through the 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 to achieve multi-angle assembly of the gear shaft 90 and expand the applicability of the equipment to different models of steering gears 80.

[0092] Optionally, it further includes: a locking cylinder 306, which is connected to the cantilever beam 304 and is arranged vertically, and its telescopic rod faces the cross beam assembly 303, so that when the cantilever beam 304 rotates to a set position, the telescopic rod extends and abuts against the cross beam 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, avoids angle deviation during assembly, and ensures the accuracy of multi-angle assembly.

[0093] Optionally, it also includes: a code reader 50, which is arranged on the cantilever beam 304 or a related component fixedly connected to the cantilever beam 304, and is used to read the two-dimensional code on the gear shaft 90, and send 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 slide cylinder 2011 and the rotating cylinder 2022. The code reader 50 reads the two-dimensional code of the gear shaft 90, and sends a signal to the controller to control the actions of each cylinder in a linked manner. The gear shaft 90 information is automatically identified and the assembly process is triggered, which reduces manual intervention and improves the degree of automation and assembly efficiency.

[0094] Exemplarily, the code reader 50 reads the two-dimensional code on the gear shaft 90, triggers the lifting cylinder 103, the ejection cylinder 1082 and the vertical cylinder 1093 to operate, so as to fix the diverter 80, and drives the support table 101 to the set position, waiting for the diverter 80 to be assembled with the gear shaft 90. In addition, the slide cylinder 2011 can also be triggered to drive the positioning device 202 equipped with the gear shaft 90 to move to the position of the diverter 80.

[0095] Optionally, it further includes: a first detection sensor, which is arranged below the crossbeam assembly 303 and faces the support platform 101. When it is detected that the support platform 101 reaches the set position, the ejection cylinder 1082 and the vertical cylinder 1093 are triggered, so that the ejector rod 1081 extends to support the first end of the diverter 80, and the limit block 1091 moves upward to clamp and fix the second end of the diverter 80 with the positioning block 1092.

[0096] The slide cylinder 2011 moves, driving the positioning device 202 to move toward the position of the steering gear 80, wherein the regulating 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, and detects the rotation angle through the encoder 2026, triggering the compensation unit 2023 to dynamically compensate for the offset angle of the gear shaft 90, and finally assembling the gear shaft 90 to the set position of the steering gear 80.

[0097] Optionally, it further includes: a second detection sensor 70, which is arranged on the cantilever beam 304 or a related component fixedly connected to the cantilever beam 304, and is used to detect the depth of insertion of the gear shaft 90 into the steering gear 80, so as to judge the assembly state of the gear shaft 90 and the steering gear 80, that is, whether the assembly is in place.

[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. The assembly position and depth data are fed back in real time to ensure that the installation is in place, avoid missing installation or improper assembly, and improve the assembly quality of the product.
