Description

Technical Field

[0001] The invention relates to the technical field of damper processing, and more specifically to a manual-automatic damper assembling device. Background Art

[0002] A damper is a device that provides resistance to movement and dissipates kinetic energy. It is mainly used to slow down the vibration or shaking of moving objects, thereby reducing unnecessary vibrations, protecting the stability of the equipment and extending its service life. The damper converts mechanical energy into heat energy through friction or other means, reduces the amplitude of vibration, and plays a stabilizing role. When processing the damper, an assembly device is usually required to press the piston rod into the damping cylinder for assembly.

[0003] Currently, in the operation of press-fitting the piston rod into the damping cylinder, most of the time a mechanical press-fitting method is adopted, in which the piston rod is directly pressed into the damping cylinder. The piston rod and the damping cylinder have an interference fit, and the piston rod is generally a slender rod. When the interference fit between the piston rod and the damping cylinder is large, excessive assembly force is very likely to cause the piston rod to bend and deform. Once the piston rod is deformed, the motion trajectory of the piston will be offset, thereby affecting the performance of the damper. In severe cases, it may even make the assembly impossible, which significantly increases the difficulty of assembly. Summary of the invention

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention sets a manual-automatic control component and an electromagnetic heating ring. When the control motor is started or the control hand wheel is manually turned, the driving shaft rotates immediately. The rotation of the driving shaft drives the vertical screw barrel to rotate synchronously through the synergistic effect of the transmission worm and the transmission worm wheel. As the vertical screw barrel rotates, the vertical stud matched with it drives the press-fitting block to move up and down, thereby performing the press-fitting task. During this process, the electromagnetic heating ring runs synchronously to heat the top of the damping cylinder. According to the principle of thermal expansion and contraction, after the top of the damping cylinder is heated, its inner diameter will expand and become larger. This change can significantly reduce the matching tightness between the piston rod and the damping cylinder, making the press-fitting process smoother, effectively overcoming the press-fitting problem caused by interference fit, and not only that, but also greatly reduces the deformation damage that may occur to the piston rod during the press-fitting process, providing a solid and powerful guarantee for the smooth assembly of the damper. 2. The present invention adopts the matching arrangement of the reciprocating heating assembly. When the connecting shaft rotates with the pressing operation, the second shaft will be driven to rotate synchronously through the two meshing second bevel gears. The rotation of the second shaft will drive the bar-shaped moving frame to move up and down reciprocatingly through the rotating arm and the eccentric rod. Then, the electromagnetic heating ring can be driven to move up and down reciprocatingly along the axial direction of the damping cylinder through the L-shaped sliding rod, the connecting sleeve, the locking plug rod and the vertical sliding rod, so as to evenly heat the top of the damping cylinder and avoid uneven expansion of the top of the damping cylinder due to local overheating or insufficient heating. 3. The present invention adopts the matching arrangement of the automatic positioning component. When the connecting shaft rotates, the driving bevel gear will be driven to rotate together through the fixed block, the extrusion spring, the first friction plate and the second friction plate. The driving bevel gear will drive the third shaft to operate synchronously through the driven bevel gear. The rotation of the third shaft will drive the two clamping plates to move synchronously toward or away from each other through the two meshing third bevel gears, the two-way screw rod, the horizontal slide rod and the L-shaped connecting rod. When the two clamping plates move toward each other to firmly clamp the damping cylinder, the damping cylinder will be accurately positioned at the center of the placement hole and just under the press-fitting block, so that in the subsequent press-fitting process, the piston rod can be accurately installed in the center position of the damping cylinder, thereby improving the assembly accuracy. In addition, since a set of overload slipping mechanism can be constructed between the fixed block, the extrusion spring, the first friction plate, the second friction plate, the driving bevel gear and the driven bevel gear, the device can automatically adapt to clamp and position damping cylinders of different thicknesses, thereby improving the application range of the device and meeting diversified production needs. 4. The present invention is provided with the adjustment unit. When the unlocking pull block is pulled or released, the vertical slide bar can be driven to move out or automatically inserted into the locking hole under the cooperation of the reset tension spring, so that the vertical slide bar can be released or fixed all the time. When the vertical slide bar is in the released state, the staff can slide the vertical slide bar up and down with the other hand to adjust the height of the electromagnetic heating ring, so as to adapt to the uniform heating of the top of the damping cylinder of different lengths, and the application range is wider; 5. The present invention adopts a collaborative linkage design among the manual-automatic control component, the press-fitting block, the transmission connection unit, the connecting shaft, the reciprocating heating component, the electromagnetic heating ring, the automatic positioning component and the clamping plate. During the assembly operation, the staff only needs to operate the manual-automatic control component to complete the entire assembly process of pressing the piston rod into the damping cylinder at one time. This integrated operation mode greatly simplifies the operating steps and reduces the manual intervention links. It not only significantly improves the assembly efficiency, but also reduces the errors that may be caused by multi-step operations, and effectively guarantees the quality and stability of the damper assembly.

DETAILED DESCRIPTION

[0018] The present invention is further described below in conjunction with specific embodiments. However, people familiar with the art should understand that the detailed description given here in conjunction with the drawings is for better explanation, and the structure of the present invention necessarily exceeds these limited embodiments. For some equivalent replacement schemes or common means, they are no longer described in detail herein, but still belong to the scope of protection of the present application.

[0019] Figure 1-Figure 8 The best embodiment of the present invention is shown below in conjunction with the attached Figure 1-Figure 8 The present invention is further described.

[0020] See attached Figure 1-Figure 8, a manual-automatic damper assembly device comprises a device base 1, an inverted U-shaped placement seat 2 and an inverted L-shaped casing 3 are fixedly arranged on the top of the device base 1, a placement hole for placing the damping cylinder is opened on the top of the U-shaped placement seat 2, and two clamping plates 11, an electromagnetic heating ring 9 and a press-fitting block 4 are arranged in sequence just above the placement hole. It should be noted that the electromagnetic heating ring 9 is an existing electromagnetic heater, which can convert electrical energy into thermal energy through the principle of electromagnetic induction to heat its interior, and is correspondingly equipped with an electromagnetic heating controller, and its specific structure and principle will not be described in detail here; L-shaped casing The shell 3 is provided with a manual-automatic control component for controlling the lifting and lowering of the pressing block 4 to press the piston rod. A connecting shaft 12 is rotatably installed on the top inner wall of the L-shaped shell 3. The manual-automatic control component is connected to a transmission connection unit for driving the connecting shaft 12 to rotate synchronously. The connecting shaft 12 is connected to a reciprocating heating component for driving the electromagnetic heating ring 9 to move up and down to uniformly heat the top of the damping cylinder. The connecting shaft 12 is also connected to an automatic positioning component for driving the two clamping plates 11 to move toward or away from each other at the same time to automatically position damping cylinders of different thicknesses.

[0021] When the press-fitting block 4 is driven to rise and fall to perform the press-fitting operation by means of the manual-automatic control component, the manual-automatic control component will drive the connecting shaft 12 to rotate synchronously through the transmission connection unit during operation. When the connecting shaft 12 rotates, it will link the reciprocating heating component to cause the electromagnetic heating ring 9 to reciprocate up and down along the axial direction of the damping cylinder. In this way, the electromagnetic heating ring 9 can evenly heat the top of the damping cylinder. According to the principle of thermal expansion and contraction, the inner diameter of the top of the damping cylinder will expand after being heated. This change can significantly reduce the fit tightness between the piston rod and the damping cylinder, making the press-fitting process smoother and more effective. The difficulty of press-fitting caused by interference fit is reduced, and the deformation damage that may occur to the piston rod during press-fitting is reduced, which effectively ensures the smooth assembly of the damper. At the same time, the rotation of the connecting shaft 12 will also drive the two clamping plates 11 to move synchronously through the automatic positioning component, so that they can move towards or away from each other at the same time. Through this action, the damping cylinders of different thicknesses can be automatically and accurately positioned to the center of the placement hole, and just under the press-fitting block 4, so that in the subsequent press-fitting link, it can be ensured that the piston rod can be accurately installed in the center position of the damping cylinder, thereby ensuring the assembly accuracy of the damper.

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 8As shown, the manual-automatic control assembly includes a vertical stud 6 fixedly mounted on the top of the press-fit block 4, and mounting holes are provided at the top and bottom of the L-shaped housing 3. A vertical screw barrel 13 is rotatably mounted in the two mounting holes. The vertical screw barrel 13 is rotatably mounted in the L-shaped housing 3. The vertical stud 6 is threadedly arranged in the vertical screw barrel 13. Through the coordinated arrangement of the vertical stud 6 and the vertical screw barrel 13, the vertical stud 6 can be driven to rise and fall through the action of the thread when the vertical screw barrel 13 rotates. A U-shaped guide rail 7 is fixedly mounted on the top of the L-shaped housing 3, and a guide slider 17 is fixedly mounted on the top of the vertical stud 6. The guide slider 17 is slidably mounted in the U-shaped guide rail 7. The matching arrangement can guide the vertical stud 6 to move only vertically up and down, and will not rotate together with the vertical stud 6, and has good stability when lifting up and down. Support rotation holes are opened on both sides of the L-shaped casing 3 that are away from each other, and a driving shaft 14 is installed in the two supporting rotation holes for common rotation. A control motor 5 is fixedly provided on the side of the L-shaped casing 3, one end of the driving shaft 14 is fixedly connected to the output end of the control motor 5, and a control handwheel 8 is fixedly installed on the other end of the driving shaft 14. A transmission worm 15 is fixedly sleeved on the driving shaft 14, and a transmission worm wheel 16 meshing with the transmission worm 15 is fixedly sleeved on the vertical screw barrel 13. The transmission worm 15 meshes with the transmission worm wheel 16, and the driving shaft 14 is connected to the transmission connection unit.

[0023] Specifically, when the control motor 5 is started or the control hand wheel 8 is manually turned, the driving shaft 14 will be driven to rotate together, and the rotation of the driving shaft 14 will drive the transmission worm 15 to rotate, and the rotation of the transmission worm 15 will drive the transmission worm wheel 16 and the vertical screw barrel 13 to rotate together. At this time, with the cooperation of the U-shaped guide rail 7 and the guide slider 17, the rotation of the vertical screw barrel 13 will drive the vertical stud 6 to move up and down, and then drive the press block 4 to rise and fall together, so that the piston rod can be pressed into the damping cylinder for assembly.

[0024] like Figure 3 As shown, the transmission connection unit includes a first rotating shaft 19 rotatably mounted on the inner wall of the side of the L-shaped housing 3, a transmission sprocket 20 is fixedly sleeved on the driving rotating shaft 14 and the first rotating shaft 19, and the two transmission sprockets 20 are connected by a transmission chain 21, and a first bevel gear 18 is fixedly sleeved on the connecting rotating shaft 12 and the first rotating shaft 19, and the two first bevel gears 18 are meshed with each other.

[0025] Specifically, when the driving shaft 14 rotates, it will drive one of the transmission sprockets 20 to rotate. Under the action of the transmission chain 21, it will drive the other transmission sprocket 20 and the first shaft 19 to rotate together. The rotation of the first shaft 19 will drive the connecting shaft 12 to rotate synchronously through the two meshing first bevel gears 18, thereby playing the role of connecting transmission.

[0026] like Figure 4As shown, the reciprocating heating assembly includes an inverted L-shaped mounting plate 22 fixedly mounted on the inner wall of the side of the L-shaped housing 3, a vertical sliding hole is provided at the top of the L-shaped mounting plate 22, an inverted L-shaped sliding rod 23 is slidably mounted in the vertical sliding hole, and the cross-section of the L-shaped sliding rod 23 is square. It should be noted that the vertical portion of the L-shaped sliding rod 23 can only slide up and down in the vertical sliding hole and will not rotate; a strip-shaped moving frame 24 is fixedly mounted at the bottom end of the L-shaped sliding rod 23, and the strip-shaped moving frame 24 is horizontally arranged, a rotating hole is provided at the side of the L-shaped mounting plate 22, a second rotating shaft 25 is rotatably mounted in the rotating hole, a rotating arm 26 is fixedly mounted at one end of the second rotating shaft 25, and a side portion of the rotating arm 26 is fixedly mounted. An eccentric rod 27 is fixedly installed, and the eccentric rod 27 is adapted to be mounted in the strip shifting frame 24. An avoidance hole is opened on the side of the L-shaped casing 3. The horizontal part of the L-shaped slide bar 23 passes through the avoidance hole and is fixedly installed with a connecting sleeve 28. A vertical slide bar 29 is slidably installed in the connecting sleeve 28. The electromagnetic heating ring 9 is fixed at the bottom end of the vertical slide bar 29. An adjusting unit for fixing the vertical slide bar 29 is connected to the connecting sleeve 28. A synchronous transmission unit for driving the second rotating shaft 25 to rotate synchronously is connected to the connecting shaft 12. The synchronous transmission unit includes two second bevel gears 30 meshing with each other. The two second bevel gears 30 are fixedly sleeved on the connecting shaft 12 and the second rotating shaft 25, respectively.

[0027] Specifically, when the connecting shaft 12 rotates, the second rotating shaft 25 will be driven to rotate synchronously through the two meshing second bevel gears 30. The rotation of the second rotating shaft 25 will drive the eccentric rod 27 to rotate in a circle through the rotating arm 26. The circular rotation of the eccentric rod 27 will drive the bar moving frame 24 to move back and forth up and down, and then the electromagnetic heating ring 9 can be driven to move back and forth up and down through the L-shaped slide bar 23, the connecting sleeve 28, the adjustment unit and the vertical slide bar 29, so that the top of the damping cylinder can be evenly heated.

[0028] like Figure 5 As shown, the adjustment unit includes a locking rod 31, a sliding hole is opened on the side of the connecting sleeve 28, and the locking rod 31 is slidably installed in the sliding hole. A plurality of locking holes are evenly opened on the side of the vertical slide bar 29, one end of the locking rod 31 extends into one of the locking holes, and the vertical slide bar 29 is adapted to the locking hole. An unlocking pull block 33 is fixedly installed on the other end of the locking rod 31, and an elastic pull-back element is installed on the unlocking pull block 33.

[0029] Specifically, when the unlocking block 33 is pulled or pushed, the vertical slide bar 29 will be moved out of or into the locking hole, thereby loosening or fixing the vertical slide bar 29. When the vertical slide bar 29 is in a loosened state, the staff can use the other hand to slide the vertical slide bar 29 up and down to adjust the height of the electromagnetic heating ring 9 to accommodate uniform heating of the top ends of damping cylinders of different lengths.

[0030] like Figure 5 As shown, the elastic pull-back element includes a reset spring 32, and both ends of the reset spring 32 are fixedly mounted on the sides of the connecting sleeve 28 and the unlocking pull block 33, respectively, and the reset spring 32 is in a stretched state.

[0031] Specifically, when the unlocking pull block 33 is released, the elastic force of the reset spring 32 will pull the unlocking pull block 33 to automatically reset, and then drive the locking rod 31 to automatically insert into the locking hole, automatically fix the vertical slide bar 29, and keep it in a fixed state.

[0032] like Figure 2 , Figure 6 and Figure 7 As shown, the automatic positioning component includes a hollow seat 10 fixedly installed on the side of the L-shaped housing 3, and horizontal sliding holes are opened on both sides of the hollow seat 10 that are away from each other. Horizontal sliding rods 35 are slidably installed in the two horizontal sliding holes. The horizontal sliding holes are rectangular holes, so that the horizontal sliding rods 35 can only move horizontally and cannot rotate. L-shaped connecting rods 36 are fixedly installed on the ends of the two horizontal sliding rods 35 that are away from each other. Two clamping plates 11 are respectively fixed on the ends of the two L-shaped connecting rods 36 that are close to each other. A bracket is fixedly installed on the side of the hollow seat 10, and a screw rod rotating hole is opened on the side of the bracket. A bidirectional screw rod 34 is rotatably installed in the screw rod rotating hole, and the external threads at both ends of the bidirectional screw rod 34 The two horizontal slide bars 35 are respectively threadedly sleeved on the two ends of the bidirectional screw rod 34, and a connecting rotating hole is opened on the side of the L-shaped housing 3, which is connected to the hollow seat 10, and a third rotating shaft 37 is rotatably installed in the connecting rotating hole. A third bevel gear 38 is fixedly sleeved on the bidirectional screw rod 34 and the third rotating shaft 37, and the two third bevel gears 38 are meshed with each other. A limiting baffle 39 is fixedly sleeved on the two horizontal slide bars 35, and the sides of the two limiting baffles 39 that are away from each other are respectively in contact with the inner walls of the hollow seat 10 that are away from each other. An overload slip transmission unit for driving the third rotating shaft 37 to rotate together is connected to the connecting rotating shaft 12.

[0033] Specifically, when the connecting shaft 12 rotates, the third shaft 37 will be driven to rotate together through the overload slip transmission unit. The rotation of the third shaft 37 will drive the two-way screw 34 to rotate synchronously through two meshing third bevel gears 38. The rotation of the two-way screw 34 will drive the two horizontal slide bars 35 to move toward or away from each other at the same time, and then the two clamping plates 11 can be driven to move toward or away from each other through the L-shaped connecting rod 36. When the two clamping plates 11 move toward each other to firmly clamp the damping cylinder, the damping cylinder will be accurately positioned in the center of the placement hole and just below the press-fitting block 4. In this way, in the subsequent press-fitting process, the piston rod can be accurately installed in the center position of the damping cylinder, ensuring that the axis coincidence of the two is maintained within the specified tolerance range, which significantly improves the assembly accuracy.

[0034] like Figure 7 As shown, the overload slip transmission unit includes two fixed blocks 40 fixedly sleeved on the connecting shaft 12, and a first friction plate 41, an extrusion spring 44, a driving bevel gear 42 and a second friction plate 43 located between the two fixed blocks 40 are movably sleeved on the connecting shaft 12. The top of the first friction plate 41 fits with the bottom of one of the fixed blocks 40, and the two ends of the extrusion spring 44 fit with the bottom of the first friction plate 41 and the top of the driving bevel gear 42 respectively. The top and bottom of the second friction plate 43 fit with the bottom of the driving bevel gear 42 and the top of the other fixed block 40 respectively. A driven bevel gear 45 meshing with the driving bevel gear 42 is fixedly sleeved on the third rotating shaft 37.

[0035] Specifically, when the connecting shaft 12 rotates, it will drive the fixed block 40 connected thereto to rotate synchronously. During this process, the extrusion spring 44 continuously applies a stable extrusion force to the first friction plate 41 and the second friction plate 43, so that the first friction plate 41 is closely attached to the surface of the fixed block 40, and the second friction plate 43 is closely attached to the surface of the driving bevel gear 42. With the friction force generated by this close fit, the driving bevel gear 42 will be driven to rotate together. The rotating driving bevel gear 42 can drive the third shaft 37 to rotate synchronously through the meshing transmission with the driven bevel gear 45, thereby driving the two clamping plates 11 move towards or away from each other at the same time. When the clamping plate 11 clamps the damping cylinder or the limit block 39 is blocked and cannot move, the rotation of the third rotating shaft 37 and the driven bevel gear 45 is also blocked. At this time, the first friction plate 41 and the second friction plate 43 will overcome the friction force, thereby causing slipping. With the occurrence of slippage, the driving bevel gear 42 loses the effective drive from the first friction plate 41 and the second friction plate 43 and will automatically stop rotating. Through the above mechanism, the device can automatically adapt to the clamping and positioning of damping cylinders of different thicknesses, thereby greatly improving the scope of application of the device.

[0036] The working principle and use process of the present invention are as follows: when in use, first insert the damping cylinder into the placement hole, and place the piston rod on the top of the damping cylinder, then start the control motor 5 or manually turn the control hand wheel 8 to drive the driving shaft 14 to rotate together, the driving shaft 14 will drive the transmission worm 15 to rotate, the transmission worm 15 will drive the transmission worm wheel 16 and the vertical screw cylinder 13 to rotate together, at this time, under the cooperation of the U-shaped guide rail 7 and the guide slider 17, the rotation of the vertical screw cylinder 13 will drive the vertical stud 6 to move up and down, and then drive the press-fitting block 4 to rise and fall together to perform the press-fitting operation; in this process, the driving shaft 14 will pass through the two transmission sprockets 20 and the transmission The moving chain 21 drives the first rotating shaft 19 to rotate together, and the rotation of the first rotating shaft 19 will drive the connecting rotating shaft 12 to rotate synchronously through the two meshing first bevel gears 18, and the rotation of the connecting rotating shaft 12 will drive the second rotating shaft 25 to rotate synchronously through the two meshing second bevel gears 30, and the rotation of the second rotating shaft 25 will drive the eccentric rod 27 to rotate in a circle through the rotating arm 26, and the circular rotation of the eccentric rod 27 will drive the bar-shaped moving frame 24 to move up and down reciprocatingly, and then the electromagnetic heating ring 9 can be driven to move up and down reciprocatingly along the axial direction of the damping cylinder through the L-shaped sliding rod 23, the connecting sleeve 28, the locking plug rod 31 and the vertical sliding rod 29, so as to evenly heat the top of the damping cylinder. According to the principle of thermal expansion and contraction, when the top end of the damping cylinder is heated, its inner diameter will expand and become larger. This change can significantly reduce the fit tightness between the piston rod and the damping cylinder, making the press-fitting process smoother; at the same time, the rotation of the connecting shaft 12 will drive the fixed block 40 connected thereto to rotate synchronously. Under the elastic force of the extrusion spring 44, a stable extrusion force can be applied to the first friction plate 41 and the second friction plate 43, so that the first friction plate 41 is closely fitted to the surface of the fixed block 40, and the second friction plate 43 is closely fitted to the surface of the driving bevel gear 42. With the friction force generated by this close fit, the driving bevel gear 42 will be driven to rotate together, and the rotating driving bevel gear 4 The third rotating shaft 37 can be driven to rotate synchronously through meshing transmission with the driven bevel gear 45. The rotation of the third rotating shaft 37 will drive the bidirectional screw rod 34 to rotate synchronously through two meshing third bevel gears 38. The rotation of the bidirectional screw rod 34 will drive the two horizontal slide bars 35 to move toward or away from each other at the same time, and then drive the two clamping plates 11 to move toward or away from each other through the L-shaped connecting rod 36. When the two clamping plates 11 move toward each other to firmly clamp the damping cylinder, the damping cylinder will be accurately positioned at the center of the placement hole and just below the press-fitting block 4, so that in the subsequent press-fitting process, the piston rod can be accurately installed in the center of the damping cylinder.
