Description

Technical Field

[0001] The present invention belongs to the field of installation of sealing rings and pistons, and particularly relates to an installation device for sealing rings and pistons in a narrow space. Background Art

[0002] Sealing rings and pistons are necessary braking parts of brakes. Only by properly installing the sealing rings and pistons can the braking performance of the brakes be ensured.

[0003] However, in some narrow spaces, due to various restrictions, the installation of sealing rings and pistons can only be carried out manually. Since the diameter of the sealing ring is generally larger than the notch of the component to be installed, it is very difficult for personnel to press the sealing ring into the notch and place it into the sealing groove in a narrow space. At the same time, due to uneven force during installation, the sealing ring is extremely likely to be distorted or deformed, resulting in a bulging phenomenon after the installation of the sealing ring is completed. Including during the subsequent installation of the piston after the sealing ring is installed correctly, due to the inevitable uneven force exerted by both hands in the manual installation method, the piston will be tilted, causing the bottom of the piston to squeeze the sealing ring, and then resulting in damage to the sealing ring. The above problems seriously restrict the installation efficiency and reliability of the brakes. Summary of the Invention

[0039] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0040] 1. Through the radial displacement of the telescopic rod on the rotating disk and the cooperation with the support rod, the sealing ring is driven to undergo compressive deformation, thereby reducing the outer diameter of the sealing ring, enabling it to be directly placed into the narrow space where the sealing ring needs to be installed. Then, by retracting the telescopic rod to release the sealing ring, the sealing ring is reset under the action of its own elasticity and finally clamped in the narrow space where the sealing ring needs to be installed. The overall structure of the device is simple, the driving method is simple and reliable, and the installation of the sealing ring is realized in a fully automatic mechanical manner, liberating the labor productivity and improving the work efficiency.

[0041] 2. By coordinating with the rotation and telescopic functions of the first rotating telescopic arm and the displacement functions of the telescopic rod and the support rod, the telescopic rod and the support rod can not only play the role of clamping and releasing the sealing ring, but also play the role of rolling the sealing ring at the same time; through the three-point rolling method, it is ensured that the sealing ring can be installed in the sealing groove perfectly, and the displacement functions of the telescopic rod and the support rod can meet the parts to be processed with different diameters and ensure the fitting degree with their diameters, ensuring the rolling effect.

[0042] 3. At the same time, a corresponding sealing ring disassembly device is also configured to solve the problems of sealing ring disassembly and installation failure.

[0043] 4. This device also integrates the installation and disassembly of the sealing ring and the installation and disassembly of the piston.

Detailed implementation manners

[0051] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be described and explained below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention. Based on the embodiments provided by the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0052] Obviously, the accompanying drawings in the following description are only some examples or embodiments of the present invention. For those of ordinary skill in the art, without creative efforts, the present invention can also be applied to other similar scenarios based on these drawings. In addition, it can also be understood that although the efforts made in this development process may be complex and lengthy, for those of ordinary skill in the art related to the content disclosed in the present invention, some designs, manufacturing or production changes based on the technical content disclosed in the present invention are only conventional technical means and should not be understood as the content disclosed in the present invention being insufficient.

[0053] When "embodiment" is mentioned in the present invention, it means that the specific features, structures or characteristics described in combination with the embodiment can be included in at least one embodiment of the present invention. The phrase appears in various positions in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those of ordinary skill in the art explicitly and implicitly understand that the embodiments described in the present invention can be combined with other embodiments without conflict.

[0054] As Figure 1 and Figure 2 shown; an installation device for a sealing ring and a piston in a narrow space, comprising: a sealing ring installation device and a piston installation device;

[0055] The sealing ring installation device further includes: a rotary disk 3.

[0056] Above the rotating disk 3, there is a first rotating telescopic arm 1. Among them, the first rotating telescopic arm 1 is designed to be driven by an external driving force to rotate and extend the first rotating telescopic arm 1, drive the rotating disk 3 to rotate, and make the rotating disk 3 move reciprocally along the axial direction of the first rotating telescopic arm 1. The first rotating telescopic arm 1 can specifically be a combination of a telescopic cylinder and a rotating cylinder, or can specifically be other structural forms that can achieve the above actions; if the driving cylinder method is adopted, its external driving force can adopt the liquid drive or gas drive method, and preferably, the gas drive is more efficient and reliable.

[0057] Vertically and movably below the rotating disk 3, there is a telescopic rod 5 with a telescopic structure, and the telescopic rod 5 is driven by a displacement driving mechanism to move linearly along the radial direction of the rotating disk 3; the telescopic structure of the telescopic rod 5 is driven by an external driving force to perform telescopic movement along the axial direction of the telescopic rod. The external driving force of the telescopic rod 5 can specifically be gas drive, liquid drive, or other driving forms that can achieve the above actions. Preferably, the gas drive is simpler and more efficient.

[0058] Below the rotating disk 3, there are also a pair of support rods 8 vertically arranged on both sides of the movement track of the telescopic rod 5.

[0059] As Figure 2 shown, when performing the installation operation of the elastic sealing ring, first, the elastic sealing ring is sleeved outside the pair of support rods 8, and the outer end of the telescopic rod 5 is abutted against the outer end of the elastic sealing ring; then, by driving the telescopic rod 5 to move inward to squeeze the elastic sealing ring, the elastic sealing ring deforms, and the outer diameter of the elastic sealing ring shrinks, so that it can be placed in the sealing groove to be installed. Then, by driving the first rotating telescopic arm 1 to move, the elastic sealing ring is lowered to the position of the sealing groove to be installed. At this time, by driving the telescopic rod 5 to move outward, under the action of the deformation, the outer diameter of the elastic sealing ring gradually expands, so that one side of the edge of the elastic sealing ring is first clamped into one side of the sealing groove. At this time, by controlling the telescopic rod 5 to contract in its axial direction and separate from the elastic sealing ring, the other side of the elastic sealing ring gradually clamps into the sealing groove under the action of natural deformation, completing the installation operation of the elastic sealing ring.

[0060] After the installation operation is completed, by adjusting the position of the telescopic rod 5 on the rotating disk 3, the telescopic rod 5 is made to fit with the sealing groove, and by rotating the rotating disk 3, the elastic sealing ring is rolled to ensure the reliable installation of the sealing ring.

[0061] The piston installation device further includes: a suction cup 14;

[0062] Above the suction cup 14, there is a second rotary telescopic arm 13; the second rotary telescopic arm 13 is designed to be driven by an external driving force to rotate and extend the second rotary telescopic arm 13, and drive the suction cup 14 to rotate and make the suction cup 14 reciprocate along the axial direction of the second rotary telescopic arm 13. The external driving force mode of the second rotary telescopic arm 13 is similar to that of the first rotary telescopic arm 1, so it will not be elaborated here. Through the suction of the suction cup 14 and the extension and rotation of the second rotary telescopic arm 13, the stable installation of the piston is realized.

[0063] The above process is the installation and rolling process of the elastic sealing ring and the installation of the piston. Inevitably, during the above process, when the installation effect of the elastic sealing ring is not good or the elastic sealing ring needs to be disassembled, a corresponding disassembly device needs to be set. Therefore, on the basis of the above structure, the present application further includes: a sealing ring disassembly device.

[0064] As Figure 3 shown, the sealing ring disassembly device further includes: a buckling rod 12 and a third rotary telescopic arm 11; the end of the buckling rod 12 is provided with a tongue, and the tongue is in a hook-like structure for lifting the elastic sealing ring; the third rotary telescopic arm 11 is designed to be driven by an external driving force to rotate and extend the third rotary telescopic arm 11, and drive the buckling rod to rotate and make the buckling rod reciprocate along the axial direction of the third rotary telescopic arm 11. The external driving force mode of the third rotary telescopic arm 11 is similar to that of the first rotary telescopic arm 1, so it will not be elaborated here. Since the tongue of the buckling rod 12 is required for lifting operation, an angle adjustment driving cylinder is provided between the buckling rod 12 and the third rotary telescopic arm 11 for changing the included angle between the buckling rod and the disassembly rotary telescopic arm. The angle adjustment driving cylinder can be an air cylinder, a hydraulic cylinder, an electric push cylinder, or other structural forms that can achieve the above actions. Preferably, an air cylinder or an electric push cylinder is used, and the control method is simpler and more efficient.

[0065] As Figure 3 shown, when disassembly operation is required, the angle adjustment driving cylinder drives the buckling rod 12 to move, lifts the elastic sealing ring through the tongue, and then the third rotary telescopic arm 11 rotates and extends to slowly and evenly hook and remove the elastic sealing ring.

[0066] In some embodiments, as Figure 1 and Figure 2As shown in the figure, a main chute 4 is provided in the diameter direction of the rotating disk 3, and the shaft seat end of the telescopic rod 5 is slidably clamped on the main chute 4; the displacement driving mechanism is a main chute driving cylinder 6, and the main chute driving cylinder 6 is arranged on one side of the main chute 4 and connected to the shaft seat end of the telescopic rod 5. The main chute driving cylinder 6 can be a pneumatic cylinder, a hydraulic cylinder, an electric push cylinder, or other structural forms that can achieve the above actions. Preferably, a pneumatic cylinder or an electric push cylinder is used, and the control method is simpler and more efficient. The telescopic rod 5 is pushed by the main chute driving cylinder 6 to reciprocate along the main chute 4 to ensure the stability of the telescopic rod 5 during movement.

[0067] In some embodiments, such as Figure 1 and Figure 2 As shown in the figure, a pair of side chutes 7 are symmetrically arranged on both sides of the main chute 4; the upper end of each support rod 8 is slidably clamped in each side chute 7; the upper end of each support rod 8 is connected to a side chute driving cylinder 9. The side chute driving cylinder 9 can be a pneumatic cylinder, a hydraulic cylinder, an electric push cylinder, or other structural forms that can achieve the above actions. Preferably, a pneumatic cylinder or an electric push cylinder is used, and the control method is simpler and more efficient. Through the above settings, the position of the support rod 8 can be adjusted, which can not only better ensure the stability when squeezing and clamping the elastic sealing ring, but also better adapt to sealing rings of different calibers and subsequent rolling operations.

[0068] In some embodiments, a connection frame 2 with a gantry structure is fixedly connected between the first rotating telescopic arm 1 and the rotating disk 3.

[0069] In some embodiments, it further includes: an auxiliary clamping rod 10, which is vertically arranged below the rotating disk 3 and located between the telescopic rod 5 and any support rod 8. The auxiliary clamping rod 10 mainly plays a role in auxiliary positioning.

[0070] In some embodiments, it further includes: an installation table 15; an installation table moving bottom plate 19 is slidably installed above the base of the installation table 15, and the first rotating telescopic arm 1, the third rotating telescopic arm 11, and the second rotating telescopic arm 13 are all slidably installed in parallel below the top plate of the installation table 15 through a rotating telescopic arm driving mechanism; the included angle between the driving direction of the rotating telescopic arm driving mechanism and the moving direction of the installation table moving bottom plate is 90°. Place the part to be processed on the installation table moving bottom plate 19 and move it to the designated rotating telescopic arm below for operation according to its requirements. For example, in the appendix Figure 5 It is a specific installation and disassembly of the sealing ring and piston of the wind power brake. The positions of the installation table moving bottom plate 19 and the rotating telescopic arm driving mechanism are adjusted respectively according to the piston port position required for the wind power brake operation to ensure its normal operation.

[0071] In some embodiments, the rotary telescopic arm driving mechanism includes: a rotary telescopic arm movement guide rail 16, a rotary telescopic arm mounting seat 18, and a movement guide rail driving cylinder 17; the rotary telescopic arm movement guide rail 16 is installed on the top plate of the mounting table 15; the rotary telescopic arm mounting seat 18 is slidably clamped on the rotary telescopic arm movement guide rail 16; the movement guide rail driving cylinder 17 is arranged on one side of the rotary telescopic arm movement guide rail 16 and is connected to the rotary telescopic arm mounting seat 18. The movement guide rail driving cylinder 17 can be a pneumatic cylinder, a hydraulic cylinder, an electric push cylinder, or other structural forms that can achieve the above actions. Preferably, a pneumatic cylinder or an electric push cylinder is used, and the control method is simpler and more efficient.

[0072] In some embodiments, a conveyor belt is further included. The conveyor belt is arranged above the base of the mounting table 15; the mounting table moving bottom plate 19 is fixedly installed on the conveyor belt; a driving motor 21 is connected to any one of the driving wheels 20 at the end of the conveyor belt. By starting the driving motor 21, the conveyor belt is driven to move, so as to realize the position adjustment of the mounting table moving bottom plate 19.

[0073] In some embodiments, a positioning structure for fixing the component to be processed is provided on the mounting table moving bottom plate 19.

[0074] Its working principle is as follows:

[0075] First, as Figure 2 shown, the elastic sealing ring is sleeved outside a pair of support rods 8, and the outer end of the telescopic rod 5 is abutted against the outer end of the elastic sealing ring; then the telescopic rod 5 is driven by the main chute driving cylinder 6 to move inward along the direction of the main chute 4 to squeeze the elastic sealing ring, so that the elastic sealing ring deforms, thereby reducing the outer diameter of the elastic sealing ring, so that it can be placed in the sealing groove to be installed. Then, by driving the first rotary telescopic arm 1 to extend, the elastic sealing ring is lowered to the sealing groove to be installed. At this time, by driving the main chute driving cylinder 6 to drive the telescopic rod 5 to move outward along the direction of the main chute 4, under the action of the reset of the deformation, the outer diameter of the elastic sealing ring gradually expands, so that one side of the edge of the elastic sealing ring is first clamped into one side of the sealing groove. At this time, the telescopic rod 5 is controlled to contract in its axial direction to disengage it from the elastic sealing ring. Under the action of natural deformation, the other side of the elastic sealing ring is gradually clamped into the sealing groove. At this time, the telescopic rod 5 is controlled to extend and placed inside the elastic sealing ring, and the positions of the telescopic rod 5 and the support rod 8 are adjusted by the main chute driving cylinder 6 and the side chute driving cylinder 9, so that they form a rolling assembly. Under the rotary drive of the first rotary telescopic arm 1, the elastic sealing ring is rolled, so that the elastic sealing ring is perfectly installed in the corresponding sealing groove.

[0076] The above process is the installation and rolling operation of the elastic sealing ring.

[0077] As Figure 5As shown, when there are installation problems with the elastic sealing ring or when it is necessary to remove the elastic sealing ring for other reasons, the third rotating telescopic arm 11 is driven to reach the designated position, and then the angle adjustment driving cylinder drives the buckling rod 12 to move so that the tongue part of the buckling rod 12 warps the elastic sealing ring out of the sealing groove. Then, by rotating the buckling rod 12, the space for the elastic sealing ring to warp is increased. At this time, the disassembly rotating telescopic arm 11 retracts (the disassembly rotating telescopic arm 11 is always in a slow rotation state) to hook and remove the elastic sealing ring.

[0078] The above process is the disassembly operation of the elastic sealing ring.

[0079] As Figure 4 shown, when the elastic sealing ring is installed and the piston needs to be installed in the piston hole, the second rotating telescopic arm 13 is driven. Under the action of the suction cup 14, the piston is sucked into the piston installation groove of the suction cup 14. Then, through the cooperation of the second rotating telescopic arm 13 and the suction cup 14, the piston is slowly installed in the designated piston hole. The piston is evenly stressed during the process of entering the hydraulic cylinder and will not squeeze the sealing ring.

[0080] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0081] The above-described embodiments only represent several implementation manners of the present invention. Their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the appended claims.
