Description
Technical Field
[0001] This invention relates to the field of injection molding machine technology, and in particular to an auxiliary installation device for a three-platen injection molding machine connecting rod. Background Technology
[0002] A three-platen injection molding machine (or simply three-platen machine) has three platens: the front platen (head plate), the moving platen (middle plate), and the rear platen (tail plate). Due to its stable mechanical structure, simple hydraulic system, mechanical self-locking capability, and force amplification effect, the three-platen machine has gained widespread attention from users and has become the standard machine for mass production.
[0003] The most important component in the clamping system of the three-plate machine is the toggle linkage mechanism. The rear connecting rod and toggle need to be installed on the rear platen, and the front connecting rod needs to be installed on the moving platen. During the installation process, a crane is required. During installation, the workers lift these connecting rods one by one and continuously operate the crane to find the best installation position of the connecting rod until the hole on the connecting rod is aligned with the pin ear hole on the platen. Then, the pin is tapped from the side with a copper rod to connect the connecting rod and the platen.
[0004] This assembly method is slow, requiring each connecting rod to be hoisted individually, resulting in long crane usage time. Furthermore, determining the optimal installation position for the hoisted connecting rods is difficult, placing high demands on the workers' assembly skills. Existing technologies, such as Chinese patent document CN211941807U, disclose a connecting rod locking shaft installation device for a large injection molding machine, but do not include an auxiliary installation device for the connecting rod elbow.
[0005] Therefore, there is an urgent need to design a connecting rod auxiliary installation device that can achieve synchronous installation of connecting rods, is applicable to both rear and moving templates, and is highly practical and efficient in assembly. Summary of the Invention
[0006] The purpose of this invention is to address the problems of slow installation speed, the need for one-by-one hoisting by overhead crane, long crane time, difficulty in finding the installation position of the hoisted link, and low assembly accuracy of existing three-plate machine connecting rods. This invention provides an auxiliary installation device for three-plate machine connecting rods that enables synchronous installation, has a simple structure, strong versatility, convenient adjustment of the connecting rod installation position, and is highly practical and versatile. It also reduces crane time, simplifies the assembly process, and improves assembly efficiency.
[0007] The technical solution adopted by this invention to achieve its objective is as follows: a three-plate machine connecting rod auxiliary installation device, comprising a lifting module, a tooling platform module, and a moving module. The lifting module includes a linear guide rail assembly and a lifting drive mechanism. The tooling platform module is connected to the linear guide rail assembly and is driven to move up and down by the lifting drive mechanism. The tooling platform module is equipped with a transverse component and a height-adjustable sliding push rod mechanism. The moving module is mounted on the transverse component and reciprocates laterally along the transverse component. The moving module includes a forward and backward support guide mechanism that moves longitudinally along the moving module. The forward and backward support guide mechanism is equipped with several rollers and a spring clamping roller assembly. This three-plate machine connecting rod auxiliary installation device enables the tooling platform module to move up and down by setting a linear guide rail assembly in the lifting module. Furthermore, to achieve this vertical movement, a lifting drive mechanism is also provided in the lifting module. The lifting drive mechanism drives the tooling platform module to move up and down with high precision and stability, facilitating the assembly of connecting rods or toggle switches. To achieve a versatile design and meet the requirement of synchronous installation of the rear template and moving template connecting rods, a transverse component and a sliding push rod mechanism are incorporated into the tooling platform module. Multiple moving modules can be freely configured on the transverse component according to the number of connecting rods or elbows to be installed. These moving modules can reciprocate laterally along the transverse component, facilitating alignment between the connecting rods or elbows to be installed and the mounting holes on the template to ensure assembly accuracy. For convenient feeding of the connecting rods or elbows, a forward / backward support and guide mechanism is included in the moving module, comprising several rollers and elastic clamping roller assemblies. During assembly, the connecting rods or elbows rotate on the rollers and are elastically clamped by the elastic clamping roller assemblies, enabling linear forward and backward movement of the connecting rods or elbows. To achieve synchronous feeding of the connecting rods and / or elbows, a height-adjustable sliding push rod mechanism is slidably mounted on the tooling platform module. This mechanism simultaneously pushes the connecting rods or elbows to move synchronously, achieving synchronous assembly. During the pushing process, the height of the sliding push rod mechanism can be adjusted according to the different force applied to the pushing parts. This three-plate machine connecting rod auxiliary installation device has a simple and reasonable structure, strong versatility, convenient adjustment of the connecting rod installation position, and easy realization of synchronous installation of the connecting rod. It is applicable to both the rear template and the moving template, has strong practicality, can reduce the time occupied by the crane, simplify the assembly process, and improve assembly efficiency.
[0008] Preferably, the sliding push rod mechanism is slidably connected to both sides of the tooling platform module, and the sliding push rod mechanism is movably engaged with the forward and backward support guide mechanism, thus pushing the forward and backward support guide mechanism to move longitudinally. The movable engagement between the sliding push rod mechanism and the forward and backward support guide mechanism facilitates the placement of connecting rods or elbows, and also facilitates the simultaneous assembly of connecting rods or elbows to be assembled via the sliding push rod mechanism. A single push can achieve the simultaneous assembly of a pair of connecting rods and a pair of elbows, making operation convenient.
[0009] Preferably, the lateral movement assembly includes a set of lateral linear guide rails and a lateral slider slidably mounted on the lateral linear guide rails, with limiting members at both ends of the lateral linear guide rails. The lateral movement assembly mainly comprises lateral linear guide rails and a lateral slider, thereby realizing the lateral movement of the moving module, and further adjusting the lateral displacement of the connecting rod or elbow to be installed, to achieve alignment adjustment with the template installation position. The limiting members are provided to prevent lateral movement of the moving module during installation.
[0010] Preferably, the moving module further includes a transverse plate connected to the transverse slider and a forward / backward guide rail assembly disposed on the surface of the transverse plate. The forward / backward guide rail assembly includes a forward / backward linear guide rail and a forward / backward slider slidably disposed on the forward / backward linear guide rail. To facilitate the connection between the moving module and the transverse slider, the moving module is also provided with a transverse plate, and the forward / backward guide rail assembly is provided on the transverse plate to facilitate the longitudinal movement of the forward / backward support and guide mechanism.
[0011] Preferably, the advance and retreat support guide mechanism is connected to the advance and retreat slider and drives the slider to slide back and forth along the advance and retreat linear guide rail.

The advance / retreat support and guide mechanism mainly includes an advance / retreat seat for placing the connecting rod or toggle to be assembled. To facilitate the feeding of the advance / retreat seat, a push groove is provided at its rear end. When the advance / retreat support and guide mechanism needs to be advanced, the sliding push rod mechanism is movable and engaged inside the push groove, enabling multiple sets of advance / retreat support and guide mechanisms to move together, achieving synchronous assembly operations. Placing the connecting rod or toggle on the roller and pressing it with the elastic clamping roller assemblies on both sides ensures that the connecting rod or toggle always performs a linear feed motion.
[0013] Preferably, the elastic clamping roller assembly includes a floating guide support and a rubber roller with anti-slip function rotatably mounted on the guide support. The elastic clamping roller assembly mainly comprises a floating guide support and a rubber roller. The floating structure and the rubber roller are used to clamp the connecting rod or crank without damaging it, and can meet the clamping needs of connecting rods or cranks of different specifications.
[0014] Preferably, the lifting module further includes a movable device base and a support frame vertically mounted on the movable device base. The linear guide rail assembly includes a linear guide rail mounted on the support frame and a lifting slider slidably mounted on the linear guide rail. The lifting module also includes a movable device base to support the entire device and facilitate the movement of the device.
[0015] Preferably, the lifting drive mechanism includes a drive motor, a reducer connected to the drive motor, a coupling assembly driven by the reducer, and a lifting assembly driven by the coupling assembly. The lifting drive mechanism primarily drives the coupling assembly via the drive motor, thereby causing the lifting assembly to rotate and thus achieving the lifting motion of the tooling platform module.
[0016] Preferably, the reducer is a right-angle bevel gear reducer; the coupling assembly includes a coupling and a worm input shaft disposed inside the coupling. Using a right-angle bevel gear reducer allows the power transmitted by the drive motor to be transmitted to the worm input shaft inside the two couplings, achieving force transmission through two sets of couplings, resulting in good stability.
[0017] Preferably, the lifting assembly includes a pair of lifting bases, a worm gear disposed inside the lifting bases and meshing with the worm input shaft, and a lifting screw disposed on the lifting bases and driven to rotate by the worm gear.

Detailed Implementation
[0032] The present invention will now be clearly and completely described through specific embodiments and in conjunction with the accompanying drawings.
[0033] Example 1: In Figure 1, Figure 2 In the illustrated embodiment, a three-plate machine linkage auxiliary installation device includes a lifting module 1, a tooling platform module 2, and a moving module 3. The lifting module 1 includes a linear guide rail assembly and a lifting drive mechanism. The tooling platform module 2 is connected to the linear guide rail assembly and is driven to move up and down by the lifting drive mechanism. The tooling platform module 2 is equipped with a transverse component and a height-adjustable sliding push rod mechanism. The moving module 3 is mounted on the transverse component and reciprocates laterally along the transverse component. The moving module 3 includes a forward and backward support guide mechanism that moves longitudinally along the moving module. The forward and backward support guide mechanism is equipped with several rollers 35 and a spring-loaded clamping roller assembly 36. The sliding push rod mechanism is slidably connected to both sides of the tooling platform module, and the sliding push rod mechanism is movably engaged with the forward and backward support guide mechanism, pushing the forward and backward support guide mechanism to move longitudinally.
[0034] The lifting module 1 includes a movable device base 15, a support frame 11 vertically mounted on the movable device base, a linear guide rail assembly integrated on the support frame 11, and a lifting drive mechanism integrated on the movable device base 15.
[0035] The mobile device base 15 is equipped with a plurality of omnidirectional brake wheels 10. In this embodiment, for example, four omnidirectional brake wheels 10 can be provided at the four corners of the mobile device base 15.
[0036] The linear guide assembly includes a linear guide rail 12 and lifting sliders 13 slidably disposed on the linear guide rail. In this embodiment, two linear guide rails 12 are arranged in parallel, and two lifting sliders 13 are respectively disposed on each linear guide rail 12.
[0037] The lifting drive mechanism includes a drive motor 14, a reducer 16 connected to the drive motor 14, a coupling assembly driven by the reducer 16, and a lifting assembly driven by the coupling assembly. The reducer is a right-angle bevel gear reducer. In this embodiment, one drive motor 14 is provided, and a right-angle bevel gear reducer is provided at the output end of the drive motor. The right-angle bevel gear reducer transmits power to two sets of coupling assemblies on both sides, thereby achieving synchronous reverse power transmission and driving the two sets of coupling assemblies to rotate simultaneously.
[0038] The coupling assembly includes a coupling 17 and a worm gear input shaft 171 disposed inside the coupling.
[0039] The lifting assembly includes a lifting base 18, a worm gear disposed inside the lifting base 18, and a lifting screw 19 disposed on the lifting base 18 and driven to rotate by the worm gear. The worm input shaft meshes with the worm gear and drives the worm gear to rotate.
[0040] like Figure 4 As shown, in this embodiment, there are two sets of lifting components and two sets of corresponding coupling components. The worm input shaft inside the two sets of couplings meshes with the worm gear inside the two sets of couplings, thereby transmitting power to the two sets of lifting screws. The rotation of the two sets of lifting screws drives the tooling platform module 2 to lift precisely.
[0041] like Figure 5 As shown, the tooling platform module 2 includes a lifting plate 27, a back plate 26 for sliding connection between the lifting plate 27 and the lifting guide rail 12, and a lifting sleeve 28 vertically disposed below the lifting plate 27. The back plate, the lifting sleeve 28, and the lifting plate 27 are connected to each other by reinforcing ribs 29. The lifting plate 24 is generally arranged in a rectangular plate structure, and T-shaped grooves 271 are formed on both sides of the lifting plate 27.
[0042] The tooling platform module 2 further includes a transverse moving component and a sliding push rod mechanism. The sliding push rod mechanism is slidably connected to the slide groove.
[0043] Specifically, such as Figure 3 As shown, the mobile device base 15 is provided with a vertical support frame 11 by full welding. The support frame 11 is provided with a lifting linear guide rail 12. The lifting linear guide rail 12 is provided with a lifting slider 13. The lifting slider 13 and the back plate 26 are connected by screws. The mobile device base 15 is provided with a drive motor 14. The front end of the drive motor 14 is provided with a right angle bevel gear reducer 16. A pair of couplings 17 are symmetrically provided on the left and right sides of the reducer 16. The couplings 17 are connected to the lifting base 18. The lifting base 18 is provided with a lifting screw 19. The lifting screw 19 passes through the lifting sleeve 28 and is connected to the tooling platform module 2.
[0044] The coupling 17 contains a worm gear input shaft, which meshes with a worm gear inside the lifting base 18 (neither shown in the figure). The rotational motion output by the drive motor 14 is transmitted through the right-angle bevel gear reducer 16 and the coupling 17, and then converted into the rotational motion of the worm gear input shaft. The rotation of the worm gear input shaft drives the rotation of the worm gear, which in turn drives the lead screw 19 to rotate. The lead screw 19 and the lifting sleeve 28 are fitted with a ball screw, thus enabling the tooling platform module 2 to perform lifting motion.
[0045] Specifically, the back plate 26 is fixedly connected to the lifting slider 13 by screws, and is driven by the lifting slider 13 to slide up and down along the lifting linear guide rail 12. The lifting sleeve 28 and the lead screw 19 are fitted with a ball screw.
[0046] To facilitate the movement of the connecting rod or toggle, the tooling platform module 2 also includes a sliding push rod mechanism. The sliding push rod mechanism is slidably connected to the slide groove. The sliding push rod mechanism includes a sliding push rod assembly and a locking element.
[0047] like Figure 6 As shown, the sliding push rod assembly 21 includes a push rod body 211 with an overall U-shaped structure and two push rod supports 212 slidably disposed at the two U-shaped rod ends of the push rod body 211. The push rod body 211 and the push rod supports 212 are slidably and adjustablely connected to facilitate adjustment of the height of the push rod body 211. A bearing connecting rod 215 is provided on the push rod support 212 along a direction parallel to the horizontal rod of the push rod body and extending inward. A rolling bearing 214 is provided at the end of the bearing connecting rod. The rolling bearing 214 is disposed inside a sliding groove and can slide back and forth along the sliding groove, thereby realizing the sliding of the sliding push rod assembly 21 relative to the lifting plate 27.
[0048] The locking member 213 is a set screw. The locking member is arranged on the push rod bracket 212 along the axis perpendicular to the push rod bracket 212, and in the locked state, the end of the locking member extends into the push rod bracket 212 and abuts against the push rod body 211 to achieve locking and positioning of the push rod body 211.
[0049] Specifically, the force-bearing component of the sliding push rod assembly 21 is the push rod body 211, and the supporting component is the push rod bracket 212. In order to facilitate the adjustment of the height of the push rod, the push rod body 211 can slide freely up and down in the push rod bracket 212 and be fixed by a set screw. In order to facilitate the adjustment and fixation of the push rod height at any time, a hand-tightened disc screw is selected as the set screw. At the same time, in order to increase the load-bearing capacity and improve the sliding flexibility, a deep groove ball bearing is selected as the rolling bearing.
[0050] The tooling platform module 2 also includes a transverse moving component mounted on the lifting plate 27. The transverse moving component includes a set of transverse linear guide rails 22 and multiple transverse sliders 23 slidably mounted on the transverse linear guide rails. Limiting elements are provided at both ends of the transverse linear guide rails 22, including a first limiting block 24 and a second limiting block 25. The transverse sliders 23 are used to connect with the moving module 3 and drive the moving module to perform transverse movement.
[0051] The aforementioned moving module 3 is provided in multiple sets, which are set on the transverse sliding block 23 according to installation needs, and are driven by the transverse sliding block 23 to move laterally along the lifting plate 27. The moving modules can be freely arranged on the tooling platform module according to assembly needs. For the rear template, four moving modules can be selected to realize the simultaneous installation of the rear connecting rod and the toggle. For the moving template, two moving modules can be selected to realize the synchronous installation of the front connecting rod.
[0052] like Figure 7 As shown, each moving module 3 includes a transverse plate 31, a forward and backward guide rail assembly disposed on the upper surface of the transverse plate 31, and a forward and backward support and guide mechanism disposed on the forward and backward guide rail assembly.
[0053] The aforementioned forward and backward guide rail assembly includes a forward and backward linear guide rail 32 and a forward and backward slider 33 slidably disposed on the forward and backward linear guide rail 32. The forward and backward support and guide mechanism is connected to the forward and backward slider 33 and is driven by the forward and backward slider to reciprocate along the forward and backward linear guide rail 32.
[0054] The bottom of the transverse plate 31 is connected to the transverse slider 23 and is driven by the transverse slider 23 to move laterally along the lifting plate 27.
[0055] The aforementioned forward and backward support and guide mechanism includes a forward and backward seat 34, several rollers 35 disposed inside the forward and backward seat 34, and multiple elastic clamping roller assemblies 36. The forward and backward seat is generally U-shaped and is provided with a forward and backward seat base plate 341 and two side plates 342. The forward and backward seat base plate 341 is provided with a push groove 343 at the end facing the lifting screw 19.
[0056] The rollers 35 are evenly or spaced out on the inner walls of the two side plates 342, and the rollers are horizontally arranged. The rollers are suspended and evenly arranged inside the advance and retreat seats, which facilitates the linear transmission of the connecting rod or toggle.
[0057] The roller 35 includes a roller shaft 351 and a roller body 352 rotatably connected to the roller shaft. The roller shaft is arranged perpendicular to the inner wall of the side plate, and the roller body can rotate relative to the roller shaft to realize rolling linear transmission of the connecting rod or crank.
[0058] The elastic clamping roller assembly 36 is arranged in pairs on the side wall above the roller 35.
[0059] like Figure 8 As shown, the elastic clamping roller assembly 36 includes a guide support 362, a spring 361 disposed on the guide support 362, a hanging foot 363 disposed on the guide support 362, and a rubber roller 365 with anti-slip function that is rotatably disposed on the hanging foot 363 via a pin 364.
[0060] The guide support 362 includes a fixed support 366 fixedly connected to the inner wall of the side plate of the advance / retreat seat, a guide shaft 367 vertically arranged on the fixed support 366, and a floating support 368 slidably arranged on the guide shaft 367. The spring 361 is pressed on the guide shaft between the floating support and the fixed support. The hanging foot is fixed on the floating support and floats with the floating support. The guide shaft is arranged in the horizontal direction. The pin is vertically arranged on the hanging foot and the rubber roller 365 is horizontally rotatably arranged on the hanging foot.
[0061] Specifically, the forward / reverse linear guide rail 32 is disposed on the upper surface of the transverse plate 31, and the forward / reverse linear guide rail 32 is provided with a forward / reverse slider 33, which is connected to the bottom of the forward / reverse seat 34. In order to facilitate the adjustment of the extension distance of the rear connecting rod 4 and the elbow 5 on the forward / reverse seat 34, the forward / reverse seat 34 is provided with several rollable rollers 35. In addition, in order to facilitate clamping the rear connecting rod 4 or the elbow 5, multiple sets of elastic clamping roller assemblies 36 are provided on both sides inside the forward / reverse seat 34.
[0062] like Figure 9 As shown, this embodiment takes the synchronous installation of the rear connecting rod 4 and the elbow 5 on the rear template 6 as an example to explain in detail the method of installation using the three-plate machine connecting rod auxiliary installation device.
[0063] When in use, the rear template 6 is supported, for example, by using wooden blocks to raise it. Four identical moving modules 3 are placed on the tooling platform module 2. A pair of rear connecting rods 4 and a pair of elbows 5 are respectively placed on multiple rollers 35 in the four advance and retreat seats 34.
[0064] Under the combined pressing action of the elastic clamping roller assemblies 36 on both sides, the rear connecting rod and the toggle can be placed vertically, and due to the design of multiple evenly distributed rollers, the rear connecting rod and the toggle can move forward and backward in a straight line.
[0065] Start the drive motor 14, and the tooling platform module 2 slowly rises, stopping after reaching the designated installation position.
[0066] The transverse plate 31 can be moved laterally left and right by the assembler pushing and pulling. After the transverse plate 31 is moved slowly, the position of the rear connecting rod and the toggle also moves laterally. After the transverse movement reaches the designated position that meets the installation requirements, the position of the sliding push rod assembly 21 is slightly adjusted so that it is placed in the push groove on the advance and retreat seat 34, and the four moving modules 3 are slowly pushed forward synchronously.
[0067] When the four moving modules 3 are close to the rear template 6, the position of the sliding push rod assembly 21 is readjusted and the sliding push rod assembly 21 is pushed forward. When it is close to the rear connecting rod 4 or the elbow 5, the set screw 213 is loosened, the push rod body 211 is raised, and the set screw 213 is tightened in time. The sliding push rod assembly 21 spans the four moving modules laterally in space and contacts the rear connecting rod and the elbow. With the slow push of the assembly personnel, the rear connecting rod and the elbow can be pushed forward synchronously. When the hole on the rear connecting rod 4 or the elbow 5 is pushed to the coaxial position with the ear hole on the rear template 6, the pin is installed from the side.
[0068] Then, the tooling platform module 2 is slowly lowered. After reaching the designated position, the support frame 11 is pulled to remove the entire device and move it to the other side. The above steps are repeated to continue the installation.
[0069] Example 2: like Figure 10 As shown, in this embodiment, a technical solution is provided for synchronously installing the front connecting rod 8 on the moving template 7 using the three-plate machine connecting rod auxiliary installation device.
[0070] In use, the rear template is raised with wooden blocks, and two identical moving modules 3 are placed on the tooling platform module 2. The front connecting rod can be placed on multiple rollers 35 in the two advance and retreat seats 34.
[0071] Under the combined pressing action of the elastic clamping roller assemblies 36 on both sides, the front connecting rod can be placed vertically and stationary. Furthermore, due to the design of multiple evenly distributed rollers, the front connecting rod can move forward and backward in a straight line.
[0072] Start the drive motor 14, and the tooling platform module 2 slowly rises, stopping after reaching the designated installation position.
[0073] The transverse plate 31 can be moved laterally left and right by the assembler pushing and pulling. After the transverse plate 31 is moved slowly, the position of the front connecting rod will also be moved laterally. After the transverse movement reaches the designated position that meets the installation requirements, the position of the sliding push rod assembly 21 is slightly adjusted so that it is placed in the push groove on the advance and retreat seat 34, and the two moving modules 3 are slowly pushed forward synchronously.
[0074] When the two moving modules 3 are close to the moving template 7, the position of the sliding push rod assembly 21 is readjusted and the sliding push rod assembly 21 is pushed forward. When it is close to the front connecting rod 8, the set screw 213 is loosened, the push rod body 211 is raised, and the set screw 213 is tightened in time. The sliding push rod assembly 21 spans the two moving modules laterally in space and contacts the front connecting rod 8. With the slow push of the assembly personnel, the front connecting rod 8 can be pushed forward synchronously. When it is pushed to the position where the hole on the front connecting rod 8 is coaxial with the ear hole on the moving template 7, the pin is installed from the side.
[0075] Then, the tooling platform module 2 is slowly lowered. After reaching the designated position, the support frame 11 is pulled to remove the entire device and move it to the other side. The above steps are repeated to continue the installation.
[0076] In the above embodiments, the three-plate machine linkage auxiliary installation device places the linkage or elbow to be assembled in the forward / backward seat of the moving module, which is placed on the tooling platform module. The tooling platform module, driven by a drive motor, can be adjusted for height. It is equipped with a transverse linear guide rail, connected to the moving module via a transverse slider, allowing for left and right transverse movement under external force. The moving module contains a forward / backward linear guide rail, connected to the forward / backward seat via a transverse slider. Therefore, the linkage placed in the forward / backward seat can easily achieve vertical lifting, left and right transverse movement, and forward / backward movement, providing a high degree of spatial freedom and facilitating the search for the optimal installation position. The sliding push rod assembly can span multiple moving modules and is height-adjustable. When the sliding push rod assembly is located in the push groove on the forward / backward seat, the forward and backward movement of the seat can be controlled to find the optimal installation position. Raising the sliding push rod synchronously pushes multiple linkages forward, causing them to move together and reach the designated installation position simultaneously, avoiding the problems of long installation times and low efficiency caused by individual linkage installation.
[0077] The three-plate machine connecting rod auxiliary installation device is equipped with a self-locking universal brake wheel. After one side is installed, there is no need to adjust the height of the tooling platform module. It can be directly transferred to the other side for assembly, making it more flexible and convenient to use.
[0078] The tooling platform can be freely arranged with movable modules. For the rear template, the rear connecting rod and the elbow can be placed on four movable modules respectively. Simultaneous installation can be achieved by pushing with the sliding push rod assembly. For the front connecting rod of the movable template, it can be placed on two movable modules. Simultaneous installation can also be achieved quickly by pushing with the sliding push rod assembly.
[0079] This three-plate machine linkage auxiliary installation device, based on automatic adjustment in the directions of vertical lifting, horizontal and left-right movement, and forward and backward movement, as well as the setting of sliding push rods, has a simple and reasonable structure, strong versatility, convenient adjustment of linkage installation position, easy realization of synchronous installation of linkages, and is applicable to both rear templates and moving templates. It is highly practical, can reduce the time occupied by the crane, simplify the assembly process, and improve assembly efficiency.
