Description

Technical Field

[0001] This invention relates to the field of automotive parts transfer equipment technology, specifically to an automotive steering gear transfer platform. Background Art

[0002] In the automobile manufacturing process, the transfer of the steering gear is a crucial step in the production process.

[0003] The performance of the transfer platform directly affects the efficiency and safety of steering gear transfer. In the prior art, such as the invention patent with patent number CN201910761770.0, an automobile steering gear transfer platform is disclosed, which uses a clamping mechanism to fix the steering gear by setting a fixed frame and a movable frame.

[0004] However, the transfer platform has certain limitations in actual use. Its clamping mechanism is relatively complex and cumbersome to operate. It requires multiple steps to clamp and release the steering gear, which takes a long time and affects the transfer efficiency. In addition, its fixing method is not stable enough. During the transfer process, the steering gear may shake or even fall off, which poses a safety hazard.

[0005] Therefore, there is an urgent need to design a convenient and stable automotive steering gear transfer platform to solve the problems in the existing technology. Summary of the Invention

[0006] The present invention aims to solve one of the technical problems existing in the prior art.

[0007] This application provides a car steering gear transfer platform, including a platform and several clamps. The clamps are symmetrically distributed in two rows on the platform. Each clamp includes an inner tube, an outer tube, a lifting sleeve, an annular cavity, and two pairs of clamping plates. The inner tube and the outer tube are both fixedly installed on the top surface of the platform. The annular cavity is formed between the outer ring of the inner tube and the inner ring of the outer tube. The lifting sleeve can move up and down along the inner tube. The clamping plates are rotatably sleeved on the outer ring of the lifting sleeve and establish a transmission connection with the inner ring of the outer tube. The top of the clamping plates is provided with clamping grooves. When the lifting sleeve rises or falls, each pair of clamping plates moves up and down synchronously, and the corresponding pair of clamping plates separates or closes with each other, thereby realizing the clamping and release of the car steering gear.

[0008] The fixture also includes a rotating annular groove and a rotating slider. The rotating annular groove is formed on the outer peripheral wall of the lifting sleeve, and the rotating slider is slidably installed in the rotating annular groove and fixed on the inner wall of the clamping plate.

[0009] There is a pair of rotating annular grooves, and the number of rotating sliders corresponds to the number of rotating annular grooves. Each rotating annular groove and each rotating slider slide in a one-to-one sliding fit.

[0010] The inner circumferential wall of the outer tube is provided with spiral grooves corresponding to the number of clamping plates. Each clamping plate is fixed with a transmission slider that slides in cooperation with the corresponding spiral groove. Through the cooperation between the transmission slider and the spiral groove, when the lifting sleeve moves up and down along the inner tube, the transmission slider slides along the spiral groove trajectory, driving the clamping plate to rotate around the lifting sleeve, thereby realizing the synchronous separation or closing action of the clamping plates.

[0011] The fixture also includes a reset ring groove, a reset spring, a locking element, and an unlocking element. The reset ring groove is located at the top of the inner cavity of the inner tube, and the reset spring is installed in the reset ring groove with its top end abutting against the top of the inner cavity of the lifting sleeve. When the lifting sleeve descends to the point where its top end contacts the top end of the inner tube, the locking element is used to fix the lifting sleeve. The unlocking element is used to release the locking element from fixing the lifting sleeve, allowing the lifting sleeve to detach from the fixed state.

[0012] The locking component includes symmetrically sliding inserts on the inner tube sidewall and symmetrically arranged slots on the inner wall of the lifting sleeve. A pre-tightening spring is installed between the inner ends of a pair of inserts, and the outer ends are inclined to form an upward-facing guide surface.

[0013] The unlocking component includes a fixed post fixed to the top of the inner cavity of the lifting sleeve, a rotating sleeve rotatably installed at the bottom of the fixed post, an unlocking pin fixed at the lower end of the rotating sleeve, and symmetrical lifting grooves on the side wall that slide in cooperation with the insert block. An unlocking block is provided at the top of the lifting groove, and a triangular groove for transmission with the unlocking block is provided on the top surface of the insert block.

[0014] The unlocking component also includes a lifting groove symmetrically arranged on the inner wall of the inner tube, a reset groove arranged at the bottom of the lifting groove and extending circumferentially, and a reset slider symmetrically fixed on the outer wall of the rotating sleeve. The top surface of the reset groove is inclined and the higher end is connected to the lifting groove. The reset slider can slide in the lifting groove and the reset groove.

[0015] A groove is opened at the bottom of the platform. Several unlocking rods are slidably installed in the groove through a bushing. One end of the unlocking rod is aligned with the unlocking pin, and the other end is connected to the same pull rod. A vertical plate is provided at one end of the groove. The pull rod is also slidably installed in the groove through a bushing. One end of the pull rod moves through the vertical plate and is fixed with a handle. A return spring is sleeved on the pull rod. One end of the return spring is fixed to the pull rod, and the other end abuts against the inner side wall of the vertical plate.

[0016] The top surface of the platform has columns at all four corners, and each column has an L-groove at its top. The bottom surface of the platform has L-blocks at all four corners that fit the L-grooves.

[0017] The beneficial effects of this invention are as follows:

[0018] This invention uses the lifting sleeve to drive the clamping plates to lift, separate, and close synchronously, enabling rapid clamping and release of the car steering gear. The operation steps are simple, greatly improving the transfer efficiency. At the same time, the design of the pull rod and unlocking rod allows for the simultaneous unlocking of multiple clamps, further enhancing the convenience of operation.

[0019] The clamping plate and the inner ring of the outer tube are connected by a spiral groove and a transmission slider, and the cooperation of the rotating ring groove and the rotating slider ensures the stability of the clamping plate during rotation and clamping. The setting of locking parts and return springs ensures that the lifting sleeve can be firmly fixed after it is lowered into place, effectively preventing the car steering gear from shaking or falling off during transportation, and improving the safety of transportation.

[0020] The design of the uprights, L-slots, and L-blocks on the platform allows the transfer racks to be stacked, saving storage space and facilitating transfer and management. Attached Figure Description

Detailed Implementation

[0031] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0032] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0033] The automotive steering gear transfer platform provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0034] Example 1:

[0035] This application provides an automotive steering gear transfer platform, including a platform 1 and several clamps 2. The clamps 2 are symmetrically distributed in two rows on the platform 1. Each clamp 2 includes an inner tube 21, an outer tube 22, a lifting sleeve 23, an annular cavity 24, and two pairs of clamping plates 25. The inner tube 21 and the outer tube 22 are both fixedly installed on the top surface of the platform 1. The annular cavity 24 is formed between the outer ring of the inner tube 21 and the inner ring of the outer tube 22. The lifting sleeve 23 can move up and down along the inner tube 21. The clamping plates 25 are rotatably sleeved on the outer ring of the lifting sleeve 23 and establish a transmission connection with the inner ring of the outer tube 22. The top of the clamping plate 25 is provided with a clamping groove 26. When the lifting sleeve 23 rises or falls, each pair of clamping plates 25 moves up and down synchronously, and the corresponding pair of clamping plates 25 can separate or close with each other, thereby realizing the clamping and release of the automotive steering gear.

[0036] like Figure 1 and Figure 4As shown, due to the above structure, when it is necessary to transfer the car steering gear, the end of the car steering gear is placed on the top of the lifting sleeve 23. The operator applies external force to the car steering gear, which is then transmitted to the lifting sleeve 23, causing it to move downward along the inner tube 21. During the descent of the lifting sleeve 23, the clamping plate 25, which is connected to the inner ring of the outer tube 22, will move up and down synchronously based on the transmission relationship. At the same time, as the lifting sleeve 23 descends, the clamping plate 25 will close together due to the characteristics of the transmission connection, clamping and fixing the steering gear through the clamping groove, thereby achieving stable transfer of the car steering gear. This structural design makes the operation of the transfer platform more intuitive, and the clamping of the steering gear can be completed by simply operating the lifting sleeve 23, effectively improving the transfer efficiency.

[0037] Example 2:

[0038] The difference from Embodiment 1 is that, in this embodiment, in addition to the structural features of the aforementioned embodiments, the clamp 2 also includes a rotating annular groove 27 and a rotating slider. The rotating annular groove 27 is formed on the outer peripheral wall of the lifting sleeve 23, and the rotating slider is slidably installed in the rotating annular groove 27 and fixed on the inner wall of the clamping plate 25.

[0039] In this embodiment of the application, there is a pair of rotating annular grooves 27, and the number of rotating sliders corresponds to the number of rotating annular grooves 27. Each rotating annular groove 27 and each rotating slider slide in a one-to-one manner.

[0040] like Figure 4 As shown, due to the above structure, when the lifting sleeve 23 drives the clamping plate 25 to lift and rotate, the rotating slider slides in the rotating annular groove 27. The cooperation between the rotating annular groove 27 and the rotating slider restricts the rotation direction of the clamping plate 25, ensuring its rotational stability and preventing the clamping plate 25 from shifting or shaking during rotation. On the other hand, during the process of the clamping plates 25 rotating to separate or close, the sliding of the rotating slider in the rotating annular groove 27 plays a guiding and supporting role, making the rotation of the clamping plate 25 smoother and further improving the reliability of the clamping plate 25 in clamping the car steering gear. Even if bumps are encountered during transportation, it can ensure that the clamping plate 25 stably clamps the steering gear and reduces the possibility of steering gear shaking.

[0041] Example 3:

[0042] The difference from Embodiment 2 is that, in addition to the structural features of the aforementioned embodiments, the inner circumferential wall of the outer tube 22 is provided with spiral grooves 28 corresponding to the number of clamping plates 25. Each clamping plate 25 is fixed with a transmission slider that slides in cooperation with the corresponding spiral groove 28. Through the cooperation between the transmission slider and the spiral groove 28, when the lifting sleeve 23 moves up and down along the inner tube 21, the transmission slider slides along the trajectory of the spiral groove 28, driving the clamping plate 25 to rotate around the lifting sleeve 23, thereby realizing the synchronous separation or closing action of the clamping plates 25.

[0043] like Figures 4 to 5 As shown, due to the above structure, when the lifting sleeve 23 moves up and down along the inner tube 21, the transmission slider on the clamping plate 25 will slide along the trajectory of the spiral groove 28 on the inner circumferential wall of the outer tube 22. As the transmission slider slides in the spiral groove 28, it drives the clamping plate 25 to rotate around the lifting sleeve 23, thereby realizing the synchronous separation or closing action of the clamping plate 25. This transmission method based on the spiral groove 28 and the transmission slider converts the linear lifting motion of the lifting sleeve 23 into the rotational motion of the clamping plate 25, and can precisely control the opening and closing degree of the clamping plate 25.

[0044] When the lifting sleeve 23 rises, the transmission slider rises along the spiral groove 28 and drives the clamping plate 25 to rotate outward and separate; when the lifting sleeve 23 falls, the transmission slider falls along the spiral groove 28 and drives the clamping plate 25 to rotate inward and close. Through this ingenious transmission coordination, the car steering gear can be quickly and stably clamped and released without the need for a complicated operating mechanism.

[0045] Example 4:

[0046] The difference from Embodiment 3 is that, in addition to the structural features of the aforementioned embodiments, the clamp 2 also includes a reset ring groove 29, a reset spring 210, a locking member 3, and an unlocking member 4; the reset ring groove 29 is formed at the top of the inner cavity of the inner tube 21, the reset spring 210 is installed in the reset ring groove 29, and the top of the reset spring 210 abuts against the top of the inner cavity of the lifting sleeve 23; when the lifting sleeve 23 descends to the point where the top of its inner cavity contacts the top of the inner tube 21, the locking member 3 is used to fix the lifting sleeve 23; the unlocking member 4 is used to release the locking member 3 from fixing the lifting sleeve 23, so that the lifting sleeve 23 can be released from the fixed state.

[0047] like Figure 4 As shown, due to the above structure, when the lifting sleeve 23 descends to the point where its inner cavity top contacts the top of the inner tube 21, the return spring 210 is in a compressed state, providing an upward return tendency for the lifting sleeve 23. Under the action of the pre-tightening spring 33, the insert block 31 in the locking member 3 will automatically insert into the slot 32 on the inner wall of the lifting sleeve 23, firmly fixing the lifting sleeve 23 to the inner tube 21, preventing the lifting sleeve 23 from rising unexpectedly during transportation, and ensuring that the car steering gear is stably clamped. When it is necessary to release the steering gear, the locking member 4 releases the locking member 3 from the lifting sleeve 23. The setting of the unlocking member 4 allows the operator to conveniently control the fixed and unlocked states of the lifting sleeve 23, ensuring transportation stability while facilitating the loading and unloading of the steering gear, making the transportation process safer and more efficient.

[0048] Example 5:

[0049] The difference from Embodiment 4 is that, in addition to including the structural features of the aforementioned embodiments, the locking member 3 includes symmetrically slidably inserted blocks 31 on the side wall of the inner tube 21, symmetrically arranged slots 32 on the inner wall of the lifting sleeve 23, a pre-tightening spring 33 installed between the inner ends of a pair of blocks 31, and the outer ends of both blocks 31 are inclined to form an upward-facing guide surface 34.

[0050] In this embodiment of the application, the unlocking component 4 includes a fixed post 41 fixedly disposed on the top of the inner cavity of the lifting sleeve 23, a rotating sleeve 42 rotatably mounted on the bottom of the fixed post 41, an unlocking pin 43 fixedly disposed at the lower end of the rotating sleeve 42, and a lifting groove 44 symmetrically disposed on the side wall to slide and cooperate with the insertion block 31. An unlocking pin 45 is disposed at the top of the lifting groove 44, and a triangular groove 46 is disposed on the top surface of the insertion block 31 for transmission with the unlocking pin 45.

[0051] In this embodiment of the application, the unlocking component 4 further includes a lifting groove 47 symmetrically arranged on the inner wall of the inner tube 21, a reset groove 48 arranged at the bottom of the lifting groove 47 and extending circumferentially, and a reset slider 49 symmetrically fixed on the outer wall of the rotating sleeve 42. The top surface of the reset groove 48 is inclined and the higher end is connected to the lifting groove 47. The reset slider 49 can slide in the lifting groove 47 and the reset groove 48.

[0052] like Figures 4 to 8 As shown, due to the aforementioned structure, when locking is required, the lifting sleeve 23 descends, its lower end contacts the guide surface 34, and pushes a pair of inserts 31 into the inner tube 21. The pre-tension spring 33 is compressed and stores elastic potential energy until the slot 32 moves to correspond with the inserts 31. The pre-tension spring 33 releases its elastic potential energy, pushing the outer ends of each insert 31 into the corresponding slot 32, thus fixing the lifting sleeve 23. When unlocking is required, the operator uses external force to move the unlocking lever 43, causing the rotating sleeve 42 to rotate. The unlocking lever 45 extends and engages with the triangular groove 46 on the top surface of the insert 31, pulling and pushing the insert 31 into the inner tube 21. The inner cavity moves, causing the insert 31 to exit from the slot 32 of the lifting sleeve 23, thereby releasing the locking member 3 from fixing the lifting sleeve 23. The reset slider 49 slides to the end of the reset groove 48 and the lifting groove 47. Since the top surface of the reset groove 48 is inclined and connected to the lifting groove 47, after the unlocking operation is completed, the reset slider 49 on the outer wall of the rotating sleeve 42 slides from the higher end of the reset groove 48 into the lifting groove 47 under the action of the reset spring 210, driving the rotating sleeve 42 to automatically reset, preparing for the next unlocking operation. The whole unlocking process is simple to operate, and the components are closely matched, which can reliably realize the unlocking and reset of the lifting sleeve 23.

[0053] The bottom of the fixed column 41 is provided with an annular groove, the top of the rotating sleeve 42 is provided with an annular edge, and the annular edge is symmetrically provided with arc grooves. The annular edge can be rotatably sleeved in the annular groove. The lower end of the fixed column 41 is provided with a fixing pin, and the two ends of the fixing pin are slidably engaged with a pair of annular grooves.

[0054] Example 6:

[0055] The difference from Embodiment 5 is that, in addition to including the structural features of the aforementioned embodiments, a groove 5 is opened at the bottom of the platform 1, and a plurality of unlocking rods 6 are slidably installed in the groove 5 through a bushing. One end of the unlocking rod 6 is aligned with the unlocking pin 43, and the other end is connected to the same pull rod 7. A vertical plate 8 is provided at one end of the groove 5, and the pull rod 7 is also slidably installed in the groove 5 through a bushing. After one end moves through the vertical plate 8, a handle 9 is fixedly provided. A return spring 10 is sleeved on the pull rod 7. One end of the return spring 10 is fixedly connected to the pull rod 7, and the other end abuts against the inner side wall of the vertical plate 8.

[0056] like Figure 3 As shown, due to the above structure, when multiple clamps 2 need to be unlocked at the same time, the operator only needs to pull the handle 9. The pull rod 7 slides in the groove 5 through the bushing, which drives the unlocking rod 6 connected to it to move synchronously. The unlocking rod 6, along the guide of the bushing, accurately transmits the moving force to the aligned unlocking pin 43, pushes the unlocking pin 43 to rotate, and then triggers the rotating sleeve 42 to rotate, so as to realize the synchronous unlocking of the insert blocks 31 of each clamp 2.

[0057] The return spring 10 is compressed during the pulling of the lever 7, storing elastic potential energy. When the operator releases the handle 9, the return spring 10 releases the elastic potential energy, pushes the lever 7 to reset, and drives the unlocking lever 6 back to the initial position. At the same time, the rotating sleeves 42 of each clamp 2 are also automatically reset with the cooperation of the reset slider 49, the reset groove 48, and the lifting groove 47, preparing for the next unlocking operation.

[0058] This structural design integrates the unlocking operations of multiple clamps 2 into a single handle 9 control, which greatly improves unlocking efficiency, reduces the workload of operators, and ensures the stability and reliability of the unlocking and reset process through the cooperation of components such as the return spring 10 and bushing. Even with frequent operation, it is not easy to malfunction, further optimizing the user experience of the automotive steering gear transfer platform.

[0059] Example 7:

[0060] The difference from Embodiment 6 is that, in addition to the structural features of the aforementioned embodiments, each of the four corners of the top surface of the platform 1 is provided with a column 11, each column 11 has a column 12 at its top, and each of the four corners of the bottom surface of the platform 1 is provided with an L-block 13 that is adapted to the column 12.

[0061] like Figure 1 and Figure 2As shown, due to the above structure, when stacking transfer racks, the operator aligns the L-block 13 on the bottom surface of one transfer rack with the column 12 on the top column 11 of another transfer rack, and then slowly lowers it. During the lowering process, the L-block 13 gradually embeds itself into the column 12 along its shape. Through the matching structure between the L-block 13 and the column 12, the two transfer racks are stably connected together. This stacking method not only saves storage space, but also ensures that the transfer racks maintain a stable connection after stacking, making them less prone to shaking or separation. When the transfer racks are needed, they can be easily separated without affecting the normal use of a single transfer rack, thus improving the convenience and space utilization of the transfer racks during storage and transfer.
