Description

Technical Field

[0001] The present application relates to the field of electric tools, and in particular to a press for installing a step frame. Background Art

[0002] like Figure 1 and Figure 2 The stepped frame includes a base plate 1 and a plastic frame 11. A rod 12 is fixedly connected to the base plate 1, and a socket 13 is provided on the plastic frame 11 for receiving the rod 12. To prevent the plastic frame 11 from detaching from the base plate 1, an elastic gasket clamping ring 14 is provided on the end of the rod 12 that passes through the socket 13. The elastic gasket clamping ring 14 includes a collar 141, and the inner ring of the collar 141 extends into a plurality of baffles 142. The baffles 142 are evenly distributed around the circumference of the collar 141, and the arrangement of the baffles 142 has a certain degree of elasticity. A limiting ring 121 is provided on the insertion rod 12. The operator puts the ring 141 on the insertion rod 12 and squeezes the ring 141 so that the baffle 142 on the inner circle of the ring 141 is engaged in the limiting ring 121, thereby fixing the position of the elastic gasket clamping ring 14 on the insertion rod 12. The elastic gasket clamping ring 14 is used to press the plastic frame 11 against the substrate 1 to achieve connection between the substrate 1 and the plastic frame 11.

[0003] Regarding how to push the elastic gasket clamping ring and clamp the baffle into the limit ring of the insertion rod, the traditional assembly method is to use a hollow tube to cover one end of the insertion rod, and then press the hollow tube against the elastic gasket clamping ring. The hollow tube is then struck with a hammer, causing the elastic gasket clamping ring to clamp the limit ring and clamp the plastic frame. This operation method has the risk of improper assembly due to inconsistent force, or the plastic frame may not be locked tightly due to misalignment of the center, resulting in unstable installation of the base plate and the plastic frame. Utility Model Content

[0004] In order to improve the installation effect and stability of the substrate and the plastic frame, the present application provides a press for installing a stepped frame.

[0005] The present application provides a step frame installation presser that adopts the following technical solution:

[0006] A press fitter for installing a step frame includes a casing, a push rod is slidably arranged inside the casing, and a control mechanism for controlling the extension and retraction of the push rod is arranged inside the casing, a bracket is fixedly connected to the casing, a push seat is arranged on the bracket, the push rod and the push seat are arranged opposite to each other, and the control mechanism pushes the two to approach each other to clamp the elastic gasket clamping ring into the limiting ring of the corresponding insertion rod.

[0007] By adopting this technical solution, a push rod and control mechanism are installed within the housing to achieve precise and stable push-in installation of the elastic gasket clamping ring. Compared to the traditional hammering method, this press fitter ensures that the elastic gasket clamping ring is evenly and accurately engaged within the retaining ring of the insert rod, avoiding quality risks caused by improper assembly or misalignment, and improving the installation quality and stability of the base plate and plastic frame.

[0008] Optionally, the pushing seat is cylindrical and is used for the insertion rod to pass through and push the elastic gasket clamping ring until the elastic gasket clamping ring is engaged with the limiting ring of the insertion rod.

[0009] By adopting the above technical solution, the push seat is designed to be cylindrical, which can easily be passed through by the insertion rod, and the elastic gasket clamping ring is clamped with the limit ring of the insertion rod through the pushing action. This design simplifies the installation process and improves the accuracy and efficiency of installation.

[0010] Optionally, the pushing seat is movably arranged on the bracket, and the bracket is provided with an adjustment mechanism for adjusting the position of the pushing seat, so as to control the relative distance between the pushing seat and the push rod.

[0011] By adopting the above technical solution, the push seat is movably mounted on the bracket and equipped with an adjustment mechanism to flexibly adjust the relative distance between the push seat and the push rod. This design allows the press to adapt to different sizes of step frames and insert rods, improving the versatility and adaptability of the press.

[0012] Optionally, the adjustment mechanism includes a connecting seat fixedly connected to the bracket, the connecting seat is provided with a receiving groove for accommodating the pushing seat, the connecting seat is provided with a rotating shaft, the pushing seat is provided with a waist-shaped hole, and the length of the waist-shaped hole is parallel to the axial direction of the pushing seat, a plurality of first ridges are fixedly connected to the outer wall of the pushing seat, and the plurality of first ridges are arranged at intervals along the axial direction of the pushing seat, and a second ridge for clamping the first ridges is provided on the connecting seat, and a limiting rod is hinged on the connecting seat, and the limiting rod is used to limit the pushing seat to the receiving groove, and the free end of the limiting rod is detachably fixed to the connecting seat by a screw member.

[0013] By adopting the above technical solution, the rotating shaft cooperates with the waist-shaped hole, and the first and second ridges cooperate to fix the position of the push seat on the connecting base. When the distance between the push seat and the push rod needs to be adjusted, the operator only needs to loosen the threaded member to release the limiting effect of the limit rod on the push seat. The operator can adjust the distance between the push seat and the push rod to accommodate substrates and plastic frames of different thicknesses.

[0014] Optionally, the control mechanism includes an oil pressure chamber and an air pressure chamber provided in the housing, the oil pressure chamber is filled with oil pressure oil, and a first piston is slidably provided in the oil pressure chamber, the push rod is fixedly connected to the first piston, and the push rod partially extends out of the housing, the push rod is sleeved with a spring in the oil pressure chamber, and the spring pushes the first piston, so that the push rod tends to retract into the housing;

[0015] A second piston is slidably provided in the air pressure chamber, and a piston rod is fixedly connected to the second piston. The piston rod is inserted into the oil pressure chamber, and the movement of the second piston can control the length of the piston rod inserted into the oil pressure chamber. When the length of the piston rod inserted into the oil pressure chamber increases, the push rod is pushed out of the housing;

[0016] The housing is provided with an air inlet and an air outlet for connecting to an air pump, and both the air inlet and the air outlet are communicated with the air pressure chamber.

[0017] By adopting the above technical solution, the control mechanism utilizes a combined hydraulic and pneumatic chamber design. An air pump controls the pressure changes within the pneumatic chamber, thereby moving the piston rod. The pressure changes within the hydraulic chamber and the spring's elastic force drive the push rod's extension and retraction. This control method offers the advantages of fast response and high control precision, enabling precise compression of the elastic gasket clamping ring. Furthermore, the spring ensures that the push rod automatically retracts into the housing when no external force is applied, enhancing the safety and reliability of the device.

[0018] Optionally, a pad is provided at one end of the push rod, and the pushing surface on the pad is larger than the cross section of the push rod.

[0019] By adopting this technical solution, the pad at one end of the push rod increases the contact area with the target device, thereby distributing the thrust and reducing localized pressure on the target device. This design not only improves the stability and durability of the press sealer but also protects the target device from damage. Furthermore, the pad design ensures smoother and more stable operation of the press sealer.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0021] 1. A push rod and control mechanism are installed inside the housing to achieve precise and stable push-in installation of the elastic gasket clamping ring. Compared with the traditional hammering method, this press can ensure that the elastic gasket clamping ring is evenly and accurately inserted into the limit ring of the insertion rod, avoiding quality risks caused by improper assembly or misalignment, and improving the installation effect and stability of the base plate and plastic frame.

[0030] The following is combined with Figure 3-6 This application is described in further detail.

[0031] The embodiment of the present application discloses a press for installing a step frame. Figure 3 and Figure 4 The step frame mounting press includes a housing 15, which serves as the main structure of the press, and a push rod 16 is slidably mounted within the housing. A control mechanism 2 is also disposed within the housing 15 to control the retractable movement of the push rod 16. In other embodiments, the control mechanism 2 can be implemented directly by modifying a pneumatic rivet gun, replacing the original pulling motion of the rivet gun with a reverse pushing motion.

[0032] In this embodiment of the present application, the control mechanism 2 includes an oil pressure chamber 21 and an air pressure chamber 22. A first piston 23 is slidably disposed within the oil pressure chamber 21. The push rod 16 is fixedly connected to the first piston 23 and extends outside the housing 15. A spring 24 is also sleeved around the push rod 16 within the oil pressure chamber 21. This spring 24 is used to push the first piston 23 when no external force is applied, causing the push rod 16 to retract into the housing 15.

[0033] A second piston 25 is slidably disposed within the pneumatic chamber 22. A piston rod 26 is fixedly connected to the second piston 25, and the piston rod 26 is inserted into the oil pressure chamber 21. When the second piston 25 moves within the pneumatic chamber 22, it can control the length of the piston rod 26 inserted into the oil pressure chamber 21. When the length of the piston rod 26 inserted into the oil pressure chamber 21 increases, the hydraulic oil in the oil pressure chamber 21 pushes the first piston 23 to overcome the elastic force of the spring 24 and push the push rod 16 out of the housing 15. When the length of the piston rod 26 inserted into the oil pressure chamber 21 decreases, the elastic force of the spring 24 and the oil pressure of the hydraulic oil cause the first piston 23 to move in the opposite direction within the oil pressure chamber 21, driving the push rod 16 to retract into the housing 15. The housing 15 is also provided with an air inlet 27 and an air outlet 28 for connecting to an air pump to inflate and deflate the air pressure chamber 22, thereby controlling the movement of the second piston 25 and, in turn, the length of the piston rod 26 extending into the oil pressure chamber 21. Because the travel distances of the first piston 23 and the second piston 25 are fixed, the extension and contraction of the push rod 16 on the housing 15 is fixed.

[0034] like Figure 5 and Figure 6 The housing 15 is fixedly connected to a bracket 3, which is provided with a push seat 31. The push seat 31 is a cylindrical structure for receiving the insertion rod 12 and pushing the elastic gasket clamping ring 14. The push rod 16 and the push seat 31 are arranged relative to each other. When the two are close to each other, they can push the elastic gasket clamping ring 14, causing the elastic stopper 142 to engage with the corresponding stop ring 121 of the insertion rod 12.

[0035] In order to further improve the versatility and practicality of the press fitter, in the embodiment of the present application, the push seat 31 is movably arranged on the bracket 3. The bracket 3 is provided with an adjustment mechanism 4 for adjusting the position of the push seat 31 to control the relative distance between the push seat 31 and the push rod 16. Specifically, the adjustment mechanism 4 includes a connecting seat 41 fixedly connected to the bracket 3. The connecting seat 41 is cylindrical and is provided with a receiving groove 42 for accommodating the push seat 31. A rotating shaft 43 is provided on the connecting seat 41, and a waist-shaped hole 44 for inserting the rotating shaft 43 is provided on the push seat 31. The length direction of the waist-shaped hole 44 is parallel to the axial direction of the push seat 31. A plurality of first ridges 45 are fixedly connected to the outer wall of the push seat 31, and the plurality of first ridges 45 are arranged at intervals along the axial direction of the push seat 31. The connecting seat 41 is provided with a second ridge 46 for engaging with the first ridge 45. A limiting rod 47 is hingedly connected to the connecting seat 41. The operator can tilt the limiting rod 47 to limit the ejection seat 31 within the receiving groove 42. The free end of the limiting rod 47 is removably fixed to the connecting seat 41 via a threaded member 48. The limiting rod 47 limits the ejection seat 31 within the receiving groove 42, and the second ridge 46 of the first ridge 45 engages, thereby securing the position of the ejection seat 31 on the connecting seat 41. In the embodiment of the present application, the threaded member 48 comprises a screw that passes through the limiting rod 47 and is fixedly connected to the connecting seat 41.

[0036] like Figure 4 and Figure 5 In order to reduce the pressure between the push rod 16 and the target device and protect the target device from damage, in this embodiment, a pad 17 is further provided at one end of the push rod 16, and the area of ​​the pad 17 contacting the push surface of the target device is larger than the cross-sectional area of ​​the push rod 16.

[0037] When using the step frame installation presser of this embodiment, first, insert the insertion rod 12 through the insertion hole 13 of the plastic frame 11 and fit the elastic gasket clamping ring 14 onto the insertion rod 12. Then, align the push seat 31 of the presser with the insertion rod 12. Next, the control mechanism 2 controls the push rod 16 to extend, pushing the stopper 142 of the elastic gasket clamping ring 14 to engage with the retaining ring 121 of the insertion rod 12. Finally, the control mechanism 2 is released, and the push rod 16 retracts into the housing 15 under the action of the spring 24, completing the installation process.

[0038] The step frame installation press of this embodiment can achieve fast and accurate installation of the step frame, avoiding problems such as inadequate assembly, misaligned center, and unstable installation effect in traditional installation methods, and significantly improving the installation efficiency and quality of the step frame.

[0039] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
