Description

Technical Field

[0001] This utility model belongs to the technical field of vehicle door edging, specifically relating to an automatic edging device for the cab door of engineering machinery. Background Technology

[0002] Currently, there are generally two methods for edge-sealing the cab doors of construction machinery: one is manual edge-sealing, which consumes a lot of manpower, produces poor edge-sealing quality, and increases the manufacturing time of the door; the other is edge-sealing using a punch press combined with a pressing die, which improves efficiency but requires a large area, is costly, and involves a large amount of maintenance. Both methods negatively impact the profitability of manufacturing enterprises.

[0003] However, while hydraulic presses have the advantages of small size and flexible installation, there is still room for further optimization. When not in use, the pipelines of hydraulic presses lack suitable storage space, and if the pipelines are placed randomly, they will occupy a large amount of space. Utility Model Content

[0004] The purpose of this utility model is to provide an automatic edge-sealing device for the cab door of engineering machinery, so as to solve the problem mentioned in the background art that the pipeline of the hydraulic press lacks suitable storage space when it is not in use, and that if the pipeline is placed randomly, it will occupy a lot of space.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic edge-sealing device for the cab door of engineering machinery, including a hydraulic press and an automatic edge-sealing machine installed on the left side of the hydraulic press;

[0006] The automatic edge-binding machine is internally equipped with edge-binding mold one and edge-binding mold two;

[0007] The automatic edge-binding machine is equipped with a door outer panel inside;

[0008] An inner door panel is provided on one side of the outer door panel, and two pipes are fixedly connected to the outer wall of the left end of the hydraulic press.

[0009] The left end of the hydraulic press is fixedly connected to two fixing buckles.

[0010] Preferably, a guide rod is provided on the front side of both of the fixing buckles.

[0011] Preferably, the left end outer wall of the hydraulic press has multiple insertion holes that open to the left.

[0012] Preferably, each of the two pipes has multiple fixing rings on its circular outer wall, and each of the multiple fixing rings has a plug fixedly connected to its right circular outer wall.

[0013] Preferably, a magnetic head is fixedly connected to the outer wall of the right end of each of the plurality of insertion rods.

[0014] Preferably, the plurality of magnetic heads and the hydraulic press are magnetically attracted and fixed together.

[0015] Preferably, each of the lower outer walls of the plurality of edge-binding molds 2 is provided with a hydraulic actuator a to control the operation of the edge-binding mold 2, and each of the lower outer walls of the plurality of edge-binding molds 1 is fixedly connected with a hydraulic actuator b to control the operation of the edge-binding mold 1.

[0016] Preferably, the automatic edge-wrapping machine is provided with a bottom edge-wrapping mold inside, and the bottom edge-wrapping mold is provided with a bottom support inside to support the car door.

[0019] Compared with the prior art, this utility model provides an automatic edge-sealing device for the cab door of engineering machinery, which has the following beneficial effects:

[0020] 1. By installing a fixed port, space is provided to restrict the position of the connector between the end of the pipe and the automatic edge-wrapping machine, ensuring that the interface of the end of the pipe avoids contact with the ground and remains suspended when not in use. This prevents residual oil inside the pipe from flowing around, making it convenient for staff to inspect, clean, and maintain the end of the pipe. Staff do not need to spend extra effort to find the end of the pipe or clean up the surrounding debris, and can more quickly conduct regular inspections of the end of the pipe to check for wear, aging, etc.

[0021] 2. By installing fixing rings, insert rods, magnetic heads, and insertion holes, multiple fixing rings are fitted onto the pipe body area of ​​the pipeline. The insert rods on the corresponding fixing rings can be inserted into the insertion holes opened on the hydraulic press, and the magnetic head and the hydraulic press are magnetically attracted to fix the pipeline, thereby restricting the placement of the pipeline and preventing the pipeline from changing position arbitrarily due to external factors such as personnel walking and collisions, equipment vibrations, etc. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] This utility model provides, for example Figure 1-5 The automatic edge-sealing device for the cab door of an engineering machinery shown includes a hydraulic press 1 and an automatic edge-sealing machine 3 installed on the left side of the hydraulic press 1.

[0031] The automatic edge banding machine 3 is internally equipped with edge banding mold 1 2 and edge banding mold 2 4;

[0032] The automatic hemming machine 3 has a door outer panel 5 installed inside;

[0033] A door inner panel 6 is provided on one side of the outer door panel 5. Two pipes 10 are fixedly connected to the left outer wall of the hydraulic press 1. The required outer door panel 5 and inner door panel 6 are placed in the designated position of the automatic hemming machine 3, aligning them according to design requirements to prepare for subsequent hemming operations. The hydraulic press 1 is started by turning on its switch, and the hydraulic system inside the hydraulic press 1 begins to work. High-pressure oil is delivered to the hemming mold 2 through the pipes 10. The hemming mold 2 closes under hydraulic pressure, pressing down the edge of the outer door panel 5 at a certain angle. During this process, the operator must closely monitor the operation of the hemming mold 2 to ensure... To ensure the flanging angle meets the process requirements, after the flanging operation of the first edging mold 2 is completed, the first mold is opened, and the hydraulic press 1 continues to supply high-pressure oil to the second edging mold 4 through the pipeline 10. The second edging mold 4 closes under the action of hydraulic pressure, completely fitting and pressing the flanged part of the outer door panel 5 with the inner door panel 6. The operator should observe the pressing situation of the second edging mold 4 to ensure that the outer door panel 5 and the inner door panel 6 are tightly fitted without gaps or wrinkles. After the pressing operation of the second edging mold 4 is completed, the second mold is opened. After the second mold is opened, the operator carefully removes the finished edging door workpiece from the automatic edging machine 3. During the removal process, care should be taken to avoid damaging the edged door.

[0034] Two fixing buckles 8 are fixedly connected to the outer wall of the left end of the hydraulic press 1. When the pipeline 10 does not need to be connected, the joint of the pipeline 10 can be locked inside the fixing buckles 8, and the joint can be lifted by the fixing buckles 8.

[0035] like Figure 4 As shown, guide rods 7 are provided on the front side of both fixing buckles 8.

[0036] The guide rod 7 helps the operator to accurately install the component along the direction of the guide rod 7, ensuring the accuracy of the installation position and avoiding installation deviation.

[0037] like Figure 4 and Figure 5 As shown, the left outer wall of the hydraulic press 1 has multiple insertion holes 9 that open to the left. The circular outer walls of the two pipes 10 are each provided with multiple fixing rings 11. The circular outer walls of the multiple fixing rings 11 are each fixedly connected with insertion rods 12. The right outer walls of the multiple insertion rods 12 are each fixedly connected with magnetic heads 13. The multiple magnetic heads 13 and the hydraulic press 1 are magnetically attracted and fixed together.

[0038] The fixing ring 11 is sleeved on the pipe 10. The insertion rod 12 is aligned with the insertion hole 9 and inserted. At this time, the magnetic head 13 on the outer wall of the right end of the insertion rod 12 is magnetically attracted and fixed to the outer wall of the hydraulic press 1, so that the pipe 10 can be firmly fixed to the outer wall of the left end of the hydraulic press 1, thus restricting the position of the pipe 10.

[0039] like Figure 1 As shown, the lower outer walls of multiple edge-sealing molds 2 are equipped with hydraulic actuators a14 to control the operation of edge-sealing molds 2. The lower outer walls of multiple edge-sealing molds 1 are fixedly connected with hydraulic actuators b18 to control the operation of edge-sealing molds 1. The automatic edge-sealing machine 3 is equipped with a bottom edge-sealing mold 15. The bottom edge-sealing mold 15 is equipped with a base support 16 to support the car door. The upper outer wall of the base support 16 is fixedly connected with a positioning pin 17 to position the car door. The lower outer wall of the automatic edge-sealing machine 3 is fixedly connected with a base 19.

[0040] Hydraulic actuator a14 operates based on the principle of hydraulic transmission. Hydraulic oil is pressurized by hydraulic press 1 to generate high-pressure fluid. This high-pressure hydraulic oil is delivered to the cylinder of hydraulic actuator a14 through oil pipes, pushing the piston to move. The linear motion of the piston is transmitted to the edge-wrapping mold 2 4 through mechanical connection components, thereby controlling the lifting, opening and closing of edge-wrapping mold 2 4. The working principle of hydraulic actuator b18 is the same as that of hydraulic actuator a14. Hydraulic actuator b18 also uses the pressure of the hydraulic system to drive the piston to move, thereby driving edge-wrapping mold 2 2 to perform the corresponding edge-wrapping action. The operator places the car door on the bottom support 16, so that the positioning hole on the car door is accurately fitted into the positioning pin 17 to complete the positioning of the car door. The bottom edge-wrapping mold 15 is also driven by the corresponding hydraulic actuator, so that the bottom edge-wrapping mold 15 performs the edge-wrapping operation on the bottom of the car door.

[0041] like Figure 1 As shown, the automatic edge banding machine 3 is equipped with clamping devices on both the front and rear sides to clamp the outer door panel 5 and the inner door panel 6.

[0042] When the clamping device is activated, the force generated by the drive device is transmitted to the gripper through the transmission mechanism. The gripper moves inward and clamps the outer door panel 5 and the inner door panel 6 tightly together.

[0043] The implementation principle of this embodiment is as follows: The required outer door panel 5 and inner door panel 6 are placed at the designated positions on the automatic hemming machine 3, aligning them according to design requirements to prepare for subsequent hemming operations. The hydraulic press 1 is started and its switch is turned on, activating the hydraulic system inside. High-pressure oil is delivered to the hemming mold 2 through pipeline 10. The hemming mold 2 closes under hydraulic pressure, pressing down the edge of the outer door panel 5 at a certain angle. During this process, the operator must closely monitor the operation of the hemming mold 2 to ensure the flanging angle meets the process requirements. After the hemming mold 2 completes the flanging operation, it is opened, and the hydraulic press... 1. Continue to supply high-pressure oil to the edge-sealing mold 2 4 through pipeline 10. The edge-sealing mold 2 4 closes under the action of oil pressure, completely and tightly pressing the flanged part of the outer door panel 5 with the inner door panel 6. The operator should observe the pressing situation of the edge-sealing mold 2 4 to ensure that the outer door panel 5 and the inner door panel 6 are tightly fitted without gaps or wrinkles. After the edge-sealing mold 2 4 completes the pressing operation, open the mold 2. After the mold 2 is opened, the operator carefully removes the edge-sealed door workpiece from the automatic edge-sealing machine 3. During the removal process, care should be taken to avoid damaging the edge-sealed door. When pipeline 10 does not need to be connected, the connector of pipeline 10 can be locked inside the fixing buckle 8, and the connector can be lifted by the fixing buckle 8.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
