Description

Technical Field

[0001] This invention relates to the field of locomotive assembly technology, specifically to a rubber joint transverse pressing device and its pressing process. Background Technology

[0002] In electric locomotive drive systems, rubber joints are press-fitted into the inner holes of components and other parts to be assembled. During locomotive operation, these joints serve to fix the position of components and transmit forces. Each rubber joint consists of a rubber body and flat ends. The installation angle of these flat ends directly determines the forces acting on the components. Therefore, during press-fitting, it is crucial to ensure the correct installation angle of the flat ends. Significant angle deviations can cause localized misalignment of the drive system and frame after assembly, affecting subsequent locomotive assembly. Currently, the lateral assembly of rubber joints on-site relies primarily on manual measurement and overhead crane lifting. This method, requiring two people, cannot guarantee accuracy, resulting in low installation efficiency and a high risk of rework due to angular deviations after assembly. Summary of the Invention

[0003] The purpose of this invention is to overcome the defects of the prior art and provide a transverse pressing device for rubber joints and its pressing process to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the technical solution of the present invention is as follows:

[0005] This invention provides a transverse pressing device for rubber joints, used to interference fit the rubber body of a rubber joint into the joint mounting hole of a joint mounting base. It includes a control system, a mounting platform, a pressing fixture, a pressing drive source, a first adjustable column, a second adjustable column, and a stop mechanism. The control system is electrically connected to the pressing drive source, the first adjustable column, the second adjustable column, and the stop mechanism. The component to be assembled is placed on the mounting platform. Both the first and second adjustable columns are mounted on the mounting platform. The pressing drive source is located at the upper end of the first adjustable column, and the stop mechanism is located at the upper end of the second adjustable column. After assembly with the rubber joint, the pressing fixture is clamped between the pressing drive source and the stop mechanism. The pressing fixture is placed transversely and includes a positioning guide sleeve, a guide block, and a pressing block. The positioning guide sleeve includes a guide sleeve and a positioning clamp that are fixedly connected.

[0006] The positioning hoop includes a semi-circular hoop, a first positioning wing plate, and a second positioning wing plate. One end of the semi-circular hoop is fitted and fixed on the outer circumferential surface of one end of the guide sleeve. The first positioning wing plate and the second positioning wing plate are respectively formed by extending tangentially from both ends of the semi-circular hoop. During press fitting, the other end of the semi-circular hoop is fitted and tightened with the outer circumferential surface of the joint mounting seat on the side of the component to be installed. The first positioning wing plate presses against the lower process surface of the joint mounting seat, and the second positioning wing plate presses against the upper process surface of the joint mounting seat, so that the guide hole penetrating inside the guide sleeve is coaxially positioned with the joint mounting hole. The diameter of the guide hole is larger than the diameter of the joint mounting hole.

[0007] The guide block is slidably set inside the guide sleeve and is inserted into the flat head at one end of the rubber joint. The guide block is slidably engaged with the joint mounting hole. The stop mechanism is provided with a receiving hole, which is aligned with and connected to the joint mounting hole. The depth of the receiving hole is equal to the length of the guide block and is used to receive the guide block and the positioning stop rubber joint.

[0008] The pressing block is inserted into the flat head at the other end of the rubber joint. Two guide protrusions are symmetrically arranged on the outer circumference of the pressing block. The guide protrusions cooperate with the guide grooves arranged axially in the guide hole to position the angle of the flat heads at both ends of the rubber joint. During pressing, the pressing drive source presses against the end of the pressing block and drives the pressing block to slide in the guide hole in the lateral direction.

[0009] Preferably, the first and second adjustable columns are telescopic columns that are synchronously raised and lowered, and the mounting platform is provided with an adjusting slide rail along the lateral direction, with the first adjustable column mounted on the adjusting slide rail.

[0010] More preferably, it also includes a positioning baffle for positioning the longitudinal position of the component to be installed. According to the different longitudinal position parameters of the component to be installed, the installation platform is provided with multiple T-shaped baffle slots along the transverse direction. The positioning baffle has a T-shaped structure and is inserted into the corresponding T-shaped baffle slot.

[0011] More preferably, the semicircular hoop also includes a positioning extension plate formed by extending from the outer end of the second positioning wing plate, which is adapted to the shape of the connecting surface of the joint mounting seat and fits into it.

[0012] More preferably, the guide hole includes a guide section and an insertion section. The insertion section is located at the other end of the guide sleeve, and its diameter is adapted to the distance between the bottom of the two guide grooves. The bottom of the insertion section generates two semi-annular guide step surfaces that connect to the guide section. The two guide step surfaces have a spiral guide structure with the same direction of rotation. The guide start and guide end of both are located at the same height, and the two ends are connected to two guide grooves respectively.

[0013] The present invention also provides a pressing process for pressing a rubber joint onto a component to be assembled using the above-mentioned rubber joint transverse pressing device, specifically including the following steps:

[0014] a. Positioning of the component to be installed: The component to be installed is suspended on the installation platform. The height of the first and second adjustable columns is adjusted by the control system so that the upper stop mechanism and the press-fit drive source are at the same height as the joint mounting hole of the component to be installed. The longitudinal position of the component to be installed is adjusted so that the joint mounting hole is located between the upper stop mechanism and the press-fit drive source. In the lateral direction, the control system drives the stop mechanism to abut against one end face of the joint mounting seat to position the lateral position.

[0015] b. Assembly of the press-fit fixture: Insert the flat ends of the rubber joint into the connecting guide block and the press-fit block respectively, and insert all three into the guide hole of the positioning guide sleeve at the same time. When the press-fit block is inserted, rotate the press-fit block until the guide protrusion is inserted into the guide groove to complete the angle pre-positioning of the rubber joint; connect the positioning guide sleeve to the joint mounting seat. First, put the semi-circular hoop on the outer circumferential surface of the joint mounting seat, and rotate and radially adjust the position of the semi-circular hoop until the semi-circular hoop is completely attached to the outer circumferential surface of the joint mounting seat. At the same time, the first positioning wing plate is attached to and presses the lower process surface of the joint mounting seat, and the second positioning wing plate is attached to and presses the upper process surface of the joint mounting seat. At this time, the guide hole and the joint mounting hole are coaxial, completing the angle positioning and center positioning of the rubber joint.

[0016] c. Pre-clamping operation before pressing: Adjust the position of the first adjustable column by sliding it laterally so that the driving end of the pressing drive source presses against the end of the pressing block and applies a pre-clamping force. Hold the pressing fixture by hand. Under the action of the pre-clamping force, the end of the positioning guide sleeve is pressed against the end face of the joint mounting seat. The pressing block drives the rubber joint to insert until the end face of the rubber body is pressed against the opening of the joint mounting hole. At this time, the hand-held state of the pressing fixture can be released to complete the pre-clamping.

[0017] d. Press fitting of rubber joints: The control system controls the press fitting drive source to start, and the drive end of the press fitting drive source continuously applies press fitting pressure to the press fitting block. The rubber body is continuously inserted into the joint mounting hole through interference fit. When the press fitting pressure reaches 20MPa, the pressure is held for 3s to complete the press fitting of the rubber joint.

[0018] e. Reset operation: The control system controls the press-fit drive source, the first adjustable column, the second adjustable column and the stop block mechanism to return to their initial positions respectively, removes the positioning guide sleeve from the joint mounting seat, and removes the guide block and press-fit block from the flat heads at both ends of the rubber joint to complete the reset operation and remove the assembly to be installed.

[0019] Compared with existing technologies, the rubber joint transverse pressing device of the present invention can perform transverse pressing on upright components to be assembled, which helps to ensure the stability of the components to be assembled during pressing and avoids damage to the surface of the components to be assembled. By using an independent pressing fixture to guide the rubber joint interference pressing and adjusting and locking the pressing angle, the pressing angle of the rubber joint can be accurately guaranteed, effectively avoiding material waste caused by excessive pressing angle. The driving force of the pressing drive source is transmitted to the pressing block in the pressing fixture through surface contact, which can ensure the transverse transmission of pressing force and the pressing success rate. The transverse pressing device has a simple structure, low cost, and strong operability. The pressing process using this device is simple and can be completed by a single person independently. It also has high pressing efficiency, high precision, and high pass rate. Attached Figure Description

[0027] 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 merely the best 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.

[0028] This embodiment provides a transverse pressing device for rubber joints, such as... Figures 1-6 As shown, the lateral pressing device is used to press the rubber body 61 of the rubber joint 6 into the joint mounting hole of the component to be installed 1. It includes a control system, a mounting platform 3, a pressing fixture 7, a pressing drive source 5, a first adjustable column 4, a second adjustable column 8, and a stop mechanism 9. The control system includes a control panel 2 and a handheld controller. Both the first adjustable column 4 and the second adjustable column 8 are hydraulically telescopic columns that rise and fall synchronously. The first adjustable column 4 also has a lateral position adjustment function and is equipped with an electric drive mechanism that drives the lower end of the first adjustable column 4 to move along the adjusting slide rail 32. The pressing drive source 5 is a hydraulic push rod. A hydraulic pump is installed on the mounting platform 3. The hydraulic pump is connected to and controls the first adjustable column 4, the second adjustable column 8, and the pressing drive source 5 through hydraulic pipelines and solenoid valves. The stop mechanism 9 includes a stop body 92 and a stop drive source 91. The stop drive source 91 is an electric driver with a screw. The stop body 92 is located at the tail end of the screw and is always coaxial with the push rod of the press drive source 5. The control system is electrically connected to each solenoid valve, electric driver and electric drive mechanism to control the press drive source 5, the first adjustable column 4, the second adjustable column 8 and the stop mechanism 9. The handheld controller is wirelessly connected to the control system and is equipped with lifting buttons, stop front and back adjustment buttons, column front and back movement buttons and loading and unloading buttons. The control panel 2 displays lifting height data, real-time pressing pressure data and touch screen buttons corresponding to each button on the handheld controller. With the help of the handheld controller, the operator can easily independently press the large components to be assembled 1.

[0029] The component to be installed 1 is hoisted and placed on the installation platform 3 by the hoisting device. When the positioning baffle 31 set horizontally on the installation platform 3 is in contact with the lower side plane of the component to be installed 1, its longitudinal position is defined. At this time, the joint mounting seat 11 located on the side of the component to be installed 1 should be located between the press-fitting drive source 5 and the stop mechanism 9. By adjusting the first adjustable column 4 and the second adjustable column 8, the press-fitting drive source 5 and the stop mechanism 9 are raised to a certain press-fitting height. After the press-fitting fixture 7 is assembled with the rubber joint 6, it is placed horizontally between the press-fitting drive source 5 and the stop mechanism 9.

[0030] In this process, the operators assemble the pressing fixture 7 with the rubber joint 6 offline, such as... Figures 3-5As shown, the press-fitting fixture 7 includes a positioning guide sleeve 72, a guide block 73, and a press-fitting block 74. The positioning guide sleeve 72 is used to axially extend the joint mounting hole of the joint mounting seat 11, and it includes a guide sleeve 72 and a positioning clamp 71 that are fixedly connected.

[0031] The positioning clamp 71 includes a semi-circular clamp 711, a first positioning wing plate 712, and a second positioning wing plate 713. The first positioning wing plate 712 and the second positioning wing plate 713 are respectively formed by extending tangentially from both ends of the semi-circular clamp 711. The inner diameter of the semi-circular clamp 711 should be adapted to the joint mounting seat 11. One end of the clamp 711 is fitted and welded to the outer circumferential surface of one end of the guide sleeve 72, and the other end is fitted and tightened with the outer circumferential surface of the joint mounting seat 11. During assembly, the first positioning wing plate 712 presses against the lower process surface of the joint mounting seat 11, and the second positioning wing plate 713... Plate 713 presses against the upper process surface of joint mounting seat 11. The included angle between the first positioning wing plate 712 and the second positioning wing plate 713 is slightly smaller than the included angle between the upper process surface and the lower process surface to form a clamping elastic force. After the positioning hoop 71 is fitted onto the joint mounting seat 11, one end of the guide sleeve 72 is fitted and connected to one end face of the joint mounting seat 11. At the same time, the guide hole through the guide sleeve 72 and the joint mounting hole are coaxially positioned. The diameter of the guide hole is larger than the diameter of the joint mounting hole. The rubber body 61 of the rubber joint 6 can be slidably guided by the guide hole.

[0032] The rubber joint 6 has flat heads 62 at both ends. During installation, the flat surface of the flat head 62 must be parallel to the upper surface of the ventilation duct of the component to be assembled. Since the upper and lower process surfaces have a fixed angular relationship with the upper surface of the ventilation duct, the angle of the guide sleeve 72 can be locked using a semi-circular hoop 711. Both the guide block 73 and the pressing block 74 are provided with positioning slots 742 that are inserted into the flat head 62. The flat head 62 is inserted into the positioning slot 742, and its end should not protrude from the positioning slot 742. The pressing block 74 and the guide sleeve 72 are used to adjust and lock the installation angle of the flat head 62 of the rubber joint 6. Two guide grooves 723 are axially arranged in the guide hole, parallel to the upper surface of the upper ventilation duct. Two guide protrusions 74 are symmetrically arranged on the outer circumferential surface of the pressing block 74. 1. The guide protrusion 741 and the guide groove 723 are inserted and fitted together to position the pressing angle of the rubber joint 6; the guide block 73 can slide in the guide hole and the joint mounting hole of the guide sleeve 72 to guide the front end of the rubber joint 6 into the joint mounting hole. The stop block body 92 is provided with a receiving hole, which should be larger than the joint mounting hole. When the stop block body 92 is attached to the other end of the joint mounting seat 11, the receiving hole is aligned with and connected to the joint mounting hole to receive the front end of the guide block 73. The depth of the receiving hole is equal to the length of the guide block 73. The bottom of the receiving hole is used as a limit to ensure that the rubber body 61 is installed in place and to prevent over-pressing; the pressing block 74 serves as the pressing drive for the rear end of the rubber joint 6. It is the same as the guide block 73 and can slide in the guide hole and the joint mounting hole of the guide sleeve 72.

[0033] In this embodiment, as a further technical solution, in order to adapt to different components 1 to be installed, the longitudinal position parameters of different components 1 to be installed are respectively determined, such as... Figure 2 As shown, multiple T-shaped baffle slots are opened on the installation platform 3 along the horizontal direction. The positioning baffle 31 that is inserted into it has a T-shaped structure. The component to be installed 1 is longitudinally positioned by the positioning baffle 31, and its joint mounting seat 11 is correctly placed in the middle area between the press-fit drive source 5 and the stop block mechanism 9.

[0034] In this embodiment, as a further technical solution, since the upper process surface is relatively short and the entire pressing fixture 7 has a certain weight, in order to increase clamping stability, such as Figures 3-4 As shown, a positioning extension plate 714 is formed by extending the outer end of the second positioning wing plate 713, which widens the contact area with the joint mounting seat 11. The positioning extension plate 714 is adapted to the shape of the connecting surface extending from the upper process surface and is pressed together.

[0035] In this embodiment, as a further technical solution, in order to improve the operability and convenience of inserting the press-fit block 74, such as... Figure 6 As shown, the guide hole includes a guide section 722 and an insertion section 721. The insertion section 721 is located at the other end of the guide sleeve 72, and its diameter is equal to the distance between the bottoms of the two guide grooves 723, facilitating the overall insertion of the end of the pressing block 74. Since the bottom of the insertion section 721 generates two semi-annular guide step surfaces 724 connecting the guide section 722, and the two guide step surfaces 724 have a spiral guide structure with the same direction of rotation, the guide beginnings and guide ends of both are located at the same height, and the two ends of both are connected to two guide grooves 723 respectively. 3. Therefore, after the end of the pressing block 74 is inserted into the insertion section 721, the ends of its two guide protrusions 741 abut against the corresponding guide step surfaces 724. Regardless of the insertion angle, as long as the pressing block 74 is rotated in the spiral direction, the guide protrusions 741 will spiral forward along the guide step surfaces 724 they abut against until one side of the guide groove 723 falls into it. Due to the blocking and limiting effect of the other side of the guide groove 723, the pressing block 74 can no longer rotate forward. Thus, the angle positioning operation in the assembly is achieved.

[0036] In this embodiment, as a further technical solution, the outer diameter of the press block 74 + 0.5mm = the outer diameter of the guide block 73 + 0.5mm = the outer diameter of the rubber body 61, and the press block 74 and the guide block 73 are all clearance sliding fits with the guide hole, the press block 74 and the guide block 73 are all transition sliding fits with the joint mounting hole, and the rubber body 61 is transition sliding fits with the guide hole.

[0037] The present invention also provides a method for pressing the rubber joint 6 onto the component 1 to be assembled using the transverse pressing device of the rubber joint 6 in the above-described preferred embodiment, which enables one operator to independently complete the pressing process of pressing the rubber joint 6 onto the component 1 to be assembled, specifically including the following steps:

[0038] a. Positioning of component 1 to be installed: According to the model of component 1 to be installed, select the corresponding baffle slot and insert the positioning baffle 31. Use the hoisting device to hoist component 1 to be installed onto the installation platform 3 and make its lower side fit against the positioning baffle 31 to complete the longitudinal positioning. The height of the first adjustable column 4 and the second adjustable column 8 can be manually adjusted synchronously through the handheld controller. Alternatively, the model of component 1 to be installed can be entered on the control panel 2 to recall the preset height and start the automatic height adjustment so that the block body 92, the push rod of the press-fitting drive source 5 and the joint mounting hole of component 1 to be installed are at the same height to complete the height positioning. Drive the block body 92 to extend through the handheld controller until it is close to one end face of the joint mounting seat 11 and then stop to complete the lateral positioning of one end of the joint mounting seat 11.

[0039] b. Assembly of the pressing fixture 7: First, the pressing fixture 7 and the rubber joint 6 are assembled offline. The flat ends 62 at both ends of the rubber joint 6 are respectively inserted into the guide block 73 and the pressing block 74, and all three are simultaneously inserted into the guide hole of the positioning guide sleeve 72. After the end of the pressing block 74 is inserted into the insertion section 721, the pressing block 74 is rotated until its guide protrusion 741 is screwed into the guide groove 723, completing the angle pre-positioning of the rubber joint 6. Then, the online assembly is carried out, connecting the positioning guide sleeve 72, which has been assembled offline, to the joint mounting base 11. The circular hoop 711 is inserted into and fitted onto the outer circumferential surface of the joint mounting seat 11 from one side. While rotating, a radial force is applied to adjust the position of the semi-circular hoop 711 until it is completely in contact with the outer circumferential surface of the joint mounting seat 11. At the same time, the first positioning wing plate 712 is pressed against the lower process surface of the joint mounting seat 11, the second positioning wing plate 713 is pressed against the upper process surface of the joint mounting seat 11, and the positioning extension plate 714 is pressed against the connecting surface. At this time, the guide hole and the joint mounting hole are coaxial, completing the angle positioning and center positioning operations of the rubber joint 6.

[0040] c. Pre-clamping operation before pressing: During the pre-clamping operation, the pressing fixture 7 needs to be held by hand. The electric drive mechanism is started by the hand controller, which drives the first adjustable column 4 to slide laterally along the adjusting slide rail 32 to adjust the position of the first adjustable column 4. At the same time, a pre-clamping force is applied. Since the guide slider, pressing block 74 and rubber body 61 are in sliding fit with the guide hole, and the guide slider is in sliding fit with the joint mounting hole, the adjustment force of the pre-clamping operation is very small. It can be achieved by the lateral sliding of the first adjustable column 4. The push rod end of the pressing drive source 5 presses against the end face of the pressing block 74 to apply the pre-clamping force, so that the end of the positioning guide sleeve 72 is close to one end face of the joint mounting seat 11. At the same time, the pressing block 74 drives the rubber joint 6 to be inserted until the end face of the rubber body 61 is pressed against the opening of the joint mounting hole. When the driving force rises, the electric drive mechanism stops automatically, and the pre-clamping operation is completed. At this time, the handheld state of the pressing fixture 7 can be released.

[0041] d. Pressing of rubber joint 6: The handheld controller starts the press-fit drive source 5. The push rod of the press-fit drive source 5 continuously applies press-fit pressure on the press-fit block 74. Under the guidance of the guide block 73, the rubber body 61 is continuously inserted into the joint mounting hole through interference fit. When the press-fit pressure reaches the preset press-fit pressure of 20MPa of the control system, it automatically enters the pressure holding stage. After the preset pressure holding time of 3s is reached, the press-fit drive source 5 automatically stops the press-fitting program. Thus, the press-fitting of rubber joint 6 is completed.

[0042] e. Reset operation: When the reset program is started on the control panel 2, the control system controls the press drive source 5, the first adjustable column 4, the second adjustable column 8 and the stop mechanism 9 to return to their initial positions respectively. The operator can remove the positioning guide sleeve 72 from the joint mounting seat 11 and remove the guide block 73 and the press block 74 from the flat head 62 at both ends of the rubber joint 6 respectively to complete the reset operation and hoist the component to be installed 1 off the production line.

Positioning of the component to be installed; The component to be installed is suspended on the installation platform. The height of the first adjustable column and the second adjustable column is adjusted by the control system so that the stop mechanism and the press-fit drive source on them are at the same height as the joint mounting hole of the component to be installed. The longitudinal position of the component to be installed is adjusted so that the joint mounting hole is located between the upper stop mechanism and the press-fit drive source. In the lateral direction, the control system drives the stop mechanism to abut against one end face of the joint mounting seat to position the lateral position. b. Assembly of the press-fit fixture: The flat ends of the rubber joint at both ends are respectively inserted into the guide block and the press-fit block, and all three are simultaneously inserted into the guide hole of the positioning guide sleeve. When inserted into the press-fit block, the press-fit block is rotated until the guide protrusion is inserted into the guide groove, completing the angle pre-positioning of the rubber joint. The positioning guide sleeve is connected to the joint mounting base. First, the semi-circular hoop is fitted onto the outer circumferential surface of the joint mounting base. The position of the semi-circular hoop is rotated and radially adjusted until the semi-circular hoop is completely fitted to the outer circumferential surface of the joint mounting base. Simultaneously, the first positioning wing plate is pressed against the lower process surface of the joint mounting base, and the second positioning wing plate is pressed against the upper process surface of the joint mounting base. At this time, the guide hole and the joint mounting hole are coaxial, completing the angle positioning and center positioning of the rubber joint. c. Pre-clamping operation before pressing: Adjust the position of the first adjustable column by sliding it laterally so that the driving end of the pressing drive source presses against the end of the pressing block and applies a pre-clamping force. Hold the pressing fixture by hand. Under the action of the pre-clamping force, the end of the positioning guide sleeve is pressed against the end face of the joint mounting seat. The pressing block drives the rubber joint to insert until the end face of the rubber body is pressed against the opening of the joint mounting hole. At this time, the handheld state of the pressing fixture can be released to complete the pre-clamping. d. Press-fitting of the rubber joint; The control system controls the start of the press-fitting drive source, and the drive end of the press-fitting drive source continuously applies press-fitting pressure to the press-fitting block. The rubber body is continuously inserted into the joint mounting hole through an interference fit. When the press-fitting pressure reaches 20MPa, the pressure is held for 3s to complete the press-fitting of the rubber joint. e. Reset operation; The control system controls the press-fit drive source, the first adjustable column, the second adjustable column and the stop block mechanism to return to their initial positions respectively, removes the positioning guide sleeve from the joint mounting seat, and removes the guide block and the press-fit block from the flat heads at both ends of the rubber joint respectively, completing the reset operation and removing the assembly to be installed.
