Abstract
Description
Technical Field
[0001] The present invention relates to a centering device, and more specifically, to a floating support device with automatic centering. Background Technology
[0002] Floating alignment devices are used in various production lines to align parts and then float them for positioning, thereby completing the assembly of the parts. However, existing floating alignment devices have the following drawbacks:
[0003] 1. The equipment often contains a clamping component and a lifting mechanism, which require two drive sources to drive the lifting and lowering. This results in a complex mechanism, which leads to cumbersome maintenance and troublesome synchronous debugging.
[0004] 2. The presence of multiple long-stroke linear guides in the equipment will significantly increase the space occupied, as well as the material and maintenance costs.
[0005] Therefore, to address the aforementioned issues, it is necessary to develop a floating centering device that can maintain equipment efficiency while significantly reducing equipment complexity and cost. Summary of the Invention
[0006] To address the shortcomings of existing technologies, the present invention aims to provide a floating support device with automatic centering, which has the advantages of simplified structure, reduced cost, and convenient adjustment.
[0007] To achieve the above objectives, the present invention provides the following technical solution: a floating support device with automatic centering, comprising a lifting frame, a pulling block assembly, a centering clamp assembly, and a lifting cylinder;
[0008] The centering clamp assembly is mounted on the lifting frame, one end of which is provided with a main frame hinge seat, and the other end is provided with a floating support wheel;
[0009] The lifting cylinder is connected to the lifting frame and is used to push the lifting frame to rotate along the main frame hinge seat;
[0010] The pull block assembly includes a guide rail, a mounting base, and a limiting strip. The mounting base is slidably connected to the guide rail and has several mounting holes. The limiting strip is fixedly installed on the mounting base through the mounting holes and is inclined.
[0011] The lifting frame is provided with a limit wheel on the side near the mounting base for abutting against the limit strip.
[0012] In summary, the present invention has the following beneficial effects: when the lifting cylinder extends, the cylinder causes the lifting frame to rotate counterclockwise, which raises the floating support wheel until the limit wheel located on the side is tangent to the limit strip. At this time, the lifting process stops. Thus, the rotation degree of the lifting frame is controlled by the position of the limit strip on the pull block assembly. Therefore, the present application simplifies the mechanism. Since the centering clamp assembly rotates synchronously with the lifting mechanism, the original lifting mechanism of the centering clamp assembly can be eliminated, and only the centering function is retained.
[0013] Costs are reduced because, except for the linear guide rail in the pull block assembly, the rest of the components do not have long-stroke linear guide rails, which effectively reduces costs. Attached Figure Description

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0019] Reference Figures 1 to 3 As shown, in order to achieve the above objectives, the present invention provides the following technical solution: a floating support device with automatic centering, comprising a lifting frame 1, a pulling block assembly 2, a centering clamp assembly 3, and a lifting cylinder 4;
[0020] The centering clamp assembly 3 is installed on the lifting frame 1. One end of the lifting frame 1 is provided with a main frame hinge seat 11, and the other end is provided with a floating support wheel 12.
[0021] The lifting cylinder 4 is connected to the lifting frame 1 and is used to push the lifting frame 1 to rotate along the main frame hinge seat 11;
[0022] The pull block assembly 2 includes a guide rail 21, a mounting base 22, and a limiting strip 23. The mounting base 22 is slidably connected to the guide rail 21. The mounting base 22 is provided with a plurality of mounting holes 221. The limiting strip 23 is fixedly installed on the mounting base 22 through the mounting holes 221 and is inclined.
[0023] The lifting frame 1 is provided with a limiting wheel 5 on the side near the mounting base 22 for abutting against the limiting strip 23.
[0024] In this invention, when the lifting cylinder 4 extends, the cylinder causes the lifting frame 1 to rotate counterclockwise, which raises the floating support wheel 12 until the side limit wheel 5 is tangent to the limit strip 23. At this point, the lifting process stops. Thus, the degree of rotation of the lifting frame 1 is controlled by the position of the limit strip 23 on the pull block assembly 2. This simplifies the mechanism. Since the centering clamp assembly 3 rotates synchronously with the lifting mechanism, the original lifting mechanism of the centering clamp assembly 3 can be removed, and only the centering function is retained.
[0025] Costs are reduced because, except for the linear guide in the pull block assembly 2, the rest of the components do not have long-stroke linear guides, which effectively reduces costs.
[0026] As the mechanism rotates clockwise and descends, the floating support wheel 12 descends, and the centering clamp assembly 3 tilts backward as it descends, causing the highest point to decrease.
[0027] When supporting the fitting (pipe) with the largest diameter, the central column is vertical. When it rises or falls, the vertical height difference between the highest point of the central column and the floating support wheel 12 decreases.
[0028] When the center column is designed to be vertical when supporting the largest pipe, the length of the roller of the center column can be designed to be the shortest. This allows the entire mechanism to be flipped at a smaller angle, so that the highest point of the mechanism can be lowered to the safe area.
[0029] Additionally, the pull block assembly 2 includes a servo motor for controlling the mounting base 22 to move left and right along the guide rail 21, thereby adjusting the specific position of the limit strip 23. Furthermore, the tilt angle of the limit strip 23 can be adjusted by mounting it to different mounting holes 221.
[0030] like Figure 2 As shown, the limiting strip 23 is inclined. During the flipping process of the lifting frame 1, the limiting wheel 5 can gradually come into contact with the limiting strip 23, thereby achieving the effect of slow deceleration and reducing damage to the lifting cylinder 4.
[0031] The centering clamp assembly 3 includes a support platform 31, a driving member 32, and centering columns 33. There are two centering columns 33, which are respectively located on both sides of the support platform 31. The driving member 32 is used to drive the two pairs of centering columns 33 to move towards the center of the support platform 31.
[0032] The driving component 32 includes a movable seat 321, a linkage arm 322 and a movable cylinder 323. The movable seat 321 is slidably connected to the support platform 31, and a linkage rod 34 is provided on the movable seat 321.
[0033] Two sets of linkage arms 322 are provided. One end of the linkage arm 322 is connected to the linkage rod 34, and the other end is connected to the centering column 33 on one side.
[0034] The linkage arm 322 is configured in a "√" shape, and the middle part of the linkage arm 322 is rotatably connected to the support platform 31.
[0035] The movable cylinder 323 is used to drive the movable base 321 to move.
[0036] Each linkage arm 322 is provided with a linkage slot 35 for the linkage rod 34 to be inserted.
[0037] like Figure 2 As shown, during the forward movement of the moving base 321 driven by the moving cylinder 323, the linkage rod 34 moves forward in the linkage groove 35 and abuts against the linkage arm 322. At this time, the linkage rod 34 pushes the linkage arm 322, causing the linkage arm 322 to rotate along the middle, thereby driving the centering columns 33 on both sides to move. The centering columns 33 on both sides are used to perform centering operation on the fittings (pipes).
[0038] Thus, by cooperating with the centering clamp assembly 3 and the lifting frame 1, the accessories can be centered and moved upward and forward, achieving the function of feeding.
[0039] It also includes a controller, and a sliding groove 51 is provided in the limit wheel 5. A pressure sensor 52, a pressure spring 53, and a sensing slider 54 are provided in the sliding groove 51. One end of the pressure spring 53 is connected to the pressure sensor 52, and the other end is connected to the sensing slider 54.
[0040] The controller is electrically connected to the pressure sensor 52, the moving cylinder 323, and the lifting cylinder 4 respectively. When the pressure sensor 52 is gradually triggered, the controller reduces the extension rate of the lifting cylinder 4 and causes the moving cylinder 323 to retract a specified unit distance.
[0041] The design of the limiting wheel 5 is such that when the limiting wheel 5 gradually comes into contact with the limiting bar 23, the limiting bar 23 pushes the sensing slider 54 to move into the sliding groove 51. At this time, the pressure spring 53 is compressed, thereby triggering the pressure sensor 52, causing the value of the pressure sensor 52 to change, thereby generating a sensing signal and sending it to the controller.
[0042] The controller uses a sensing signal to control the lifting cylinder 4 to reduce its extension rate, thereby protecting the extended end.
[0043] Furthermore, the moving cylinder 323 is controlled to retract slightly by a certain distance, thereby releasing the part and allowing it to move left and right within a certain range, making it easier to insert into the corresponding position.
[0044] A sponge sleeve is provided on the upper part of the central column 33. The design of this sponge sleeve allows the accessory to move and adjust to a certain range to the left and right, thereby achieving both effective limitation and appropriate movement.
[0045] A lifting frame is provided on the support platform 31, and the lifting frame is linked with the sensing slider 54.
[0046] The limit wheel 5 is rotatably connected to the lifting frame 1, and two sets of sliding groove 51, pressure sensor 52, pressure spring 53 and sensing slider 54 are provided.
[0047] Furthermore, one of the sets is equipped with a linkage component for linkage with the lifting frame.
[0048] The linkage includes a trigger switch 55 disposed in the sliding groove 51, and a lifting cylinder for driving the lifting frame to move is disposed on the support platform 31. The trigger switch 55 is connected to the lifting cylinder through a controller.
[0049] The controller includes a recording module and a control module. The recording module is used to record the types of accessories placed on the support platform 31.
[0050] The control module is connected to the lifting cylinder and is used to control the lifting distance of the lifting frame according to the type of accessory.
[0051] The design of this lifting frame allows for the use of specially structured accessories, enabling the front end of the accessories to be tilted upwards for easy insertion into the corresponding holes.
[0052] When the accessory is placed on the support platform 31, and it is quickly moved to the designated position, the limit wheel 5 abuts against the limit bar 23. At this time, the sensing slider 54 slides inward under the pushing action of the limit bar 23 and touches the trigger switch 55 to generate a trigger signal. The controller then controls the lifting frame to extend upward through the lifting cylinder, thereby pushing the front end of the accessory to tilt up, thus meeting various posture requirements.
[0053] Furthermore, the sliding groove 51 is equipped with two sets of pressure sensors 52, pressure springs 53, and sensing sliders 54. The operator can selectively rotate the limit wheel 5 to adjust whether the lifting frame needs to be triggered, thereby enabling selective control.
[0054] Furthermore, due to the different sizes and styles of the accessories, the lifting distance varies. Therefore, based on the recorded data, the extension amount of the lifting cylinder can be selectively controlled to achieve intelligent control.
[0055] Furthermore, to prevent the limit wheel 5 from rotating arbitrarily, a locking block is provided on the limit wheel 5, and a locking groove is provided on the lifting frame 1. A reset spring is also provided in the locking groove. When the limit wheel 5 needs to rotate, the limit wheel 5 is pressed and pushed. At this time, the locking block corresponds with the locking groove, thereby enabling the limit wheel 5 to rotate. When the locking block does not correspond with the locking groove, the limit wheel 5 cannot rotate. This can be referenced from the lock hole design.
[0056] The above are merely preferred embodiments of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of the present invention should also be considered within the scope of protection of the present invention.
