Technical Field
[0001] The present invention relates to the technical field of pipe clamp assembly equipment, and particularly to an automobile fuel pipe clamp assembly equipment. Background Art
[0002] Automobile fuel pipes are usually pipes connecting the fuel pump and the engine fuel injectors. Their main function is to supply fuel to the engine to ensure the normal operation of the fuel system. There are pipe clamps on the automobile fuel pipes. The pipe clamps are used to fix the connection between the fuel pipe and the joint. The automobile fuel pipe clamp assembly equipment is a special equipment for automatically or semi-automatically installing fuel pipe fixing clamps, aiming to improve production efficiency, ensure assembly accuracy and consistency. The automobile fuel pipe clamp assembly equipment can adapt to fuel pipes of multiple vehicle models and multiple specifications by replacing fixture molds and adjusting programs.
[0003] During the process of assembling fuel pipe clamps using existing equipment, we found the following problems. Since the fuel pipe and the joint usually adopt interference fit to ensure the tightness of the connection, when the fuel pipe is connected to the joint, the fuel pipe and the joint will block each other, and a sufficient large force is required to make the joint squeeze the fuel pipe to expand, so as to sleeve the fuel pipe on the joint. However, during this process, the interface of the fuel pipe will be deformed due to the extrusion with the joint, and this deformation will cause the area of the interface of the fuel pipe to become smaller and unable to be connected to the joint. This phenomenon is particularly serious when the joint and the fuel pipe are not aligned. Summary of the Invention
[0004] In order to overcome the shortcomings mentioned in the above background art, the present invention provides an automobile fuel pipe clamp assembly equipment.

[0006] Further, the auxiliary bar is fixedly connected with a main support rod for evenly expanding the fuel pipe.
[0007] Further, two auxiliary struts are slidably connected to the main strut, a first tension spring is arranged between the two auxiliary struts on the same main strut, an air pump is fixedly connected to the mounting bracket, and the main strut is communicated with the air pump through a pipeline.
[0008] Further, the sliding clamp is slidably connected to the telescopic end of the second push rod, and a spring is arranged between the two. The sliding clamp is slidably connected to a limit block, a second tension spring is arranged between the limit block and the sliding clamp, a limit groove is arranged at the telescopic end of the second push rod, and the limit block limits the sliding clamp through the limit groove.

[0014] Further, all the main struts are respectively located on the back sides of all the auxiliary strips.
[0015] Advantages of the present invention: When the oil pipe is connected to the joint, the present invention makes several auxiliary strips expand the oil pipe, thereby reducing the obstruction generated during the connection of the oil pipe and the joint due to interference fit.
[0016] Through the main strut and the auxiliary struts, the oil pipe is expanded more evenly, and when the main strut and the auxiliary struts move outward to the outside of the oil pipe, the inwardly buckled part of the oil pipe is smoothed out, thereby reducing the influence of the deformation of the oil pipe interface caused by accidental impact on the connection.
[0017] When the sliding clamp and the fixed clamp do not clamp the oil pipe, the sliding clamp and the telescopic end of the second push rod are not fixedly connected. After the sliding clamp and the fixed clamp clamp the oil pipe, the limit block locks the sliding clamp and the telescopic end of the second push rod, thereby preventing the oil pipe from sliding during the connection process.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts belong to the scope of protection of the present application. Embodiment
[0021] The embodiment disclosed herein is an assembly device for an automotive oil pipe clamp, which is used for assembling an automotive oil pipe clamp.
[0022] As Figures 1 - 4As shown in the figure, it includes a bottom plate 1. A clamping member 2 and a first push rod 5 are fixedly connected to the upper side of the bottom plate 1. The clamping member 2 and the first push rod 5 are respectively located on the left and right sides of the bottom plate 1. The clamping member 2 is an existing device for clamping the connector 3, and will not be elaborated here. A sliding plate 4 is slidably connected to the upper side of the bottom plate 1. The sliding plate 4 is located between the clamping member 2 and the first push rod 5. The telescopic end of the first push rod 5 is fixedly connected to the sliding plate 4. An installation frame 6 and a fixed clamp 9 are fixedly connected to the upper side of the sliding plate 4. A fixing member 7 and a second push rod 10 are fixedly connected to the installation frame 6 and a sliding member 8 is slidably connected thereto. The fixing member 7 and the sliding member 8 are symmetrically distributed front and back. The fixing member 7 and the sliding member 8 are used to clamp the pipe clamp 16 to increase the cross-sectional area of the pipe clamp 16 so that the oil pipe 15 can pass through it. The installation frame 6 is provided with a driving assembly for pushing the sliding member 8 to move. The driving assembly is an existing device and will not be elaborated here. A sliding clamp 11 is provided at the telescopic end of the second push rod 10. The fixed clamp 9 and the sliding clamp 11 are used to clamp the oil pipe 15. After clamping the oil pipe 15, the oil pipe 15 is pushed to be connected to the connector 3. A sliding frame 12 is slidably connected to both the fixing member 7 and the sliding member 8. The two sliding frames 12 are slidably connected. Two auxiliary bars 13 are hinged to one sliding frame 12. The diameter of the circle where the left sides of the four auxiliary bars 13 are located is larger than the outer diameter of the connection part of the connector 3. The diameter of the circle where the right sides of the four auxiliary bars 13 are located is smaller than the inner diameter of the connection part of the oil pipe 15. A torsion spring is provided between the auxiliary bar 13 and the adjacent sliding frame 12. A third push rod 14 is fixedly connected to the fixing member 7. The telescopic end of the third push rod 14 is fixedly connected to the adjacent sliding frame 12.
[0023] Working process: When using the device to clamp the pipe clamp 16 on the oil pipe 15, first place the device at the work site, then clamp the joint 3 on the clamping member 2, and then place the pipe clamp 16 between the fixing member 7 and the sliding member 8. At this time, the driving component starts and pushes the sliding member 8 to move, so that the fixing member 7 and the sliding member 8 squeeze the pipe clamp 16 to deform and accumulate force, so that the diameter of the clamp 16 becomes larger, and then the oil pipe 15 is placed on the fixing clamp 9, and at the same time, the oil pipe 15 passes through the pipe clamp 16 and covers the four auxiliary strips 1. 3. When the oil pipe 15 is placed, the second push rod 10 is started, and the telescopic end of the second push rod 10 drives the sliding clamp 11 to move downward, so that the sliding clamp 11 and the fixed clamp 9 clamp the oil pipe 15 together, and then the first push rod 5 is started, and the telescopic end of the first push rod 5 extends and pushes the sliding plate 4 to move leftward, and the sliding plate 4 drives the oil pipe 15 and the pipe clamp 16 to move leftward, and at the same time the auxiliary strip 13 moves leftward, and when the auxiliary strip 13 contacts the joint 3, the joint 3 squeezes the auxiliary strip 13, so that the auxiliary strip 13 is released. When the oil pipe 15 is moved to the specified distance, the third push rod 14 is started, and the telescopic end of the third push rod 14 drives the two sliding frames 12 to move leftward, so that the sliding frame 12 pulls the auxiliary strip 13 out from between the oil pipe 15 and the joint 3. After the pulling out is completed, the driving assembly is started to drive the sliding member 8 to move backward, so that the pipe clamp 16 is reset under its own elasticity and the connection between the oil pipe 15 and the joint 3 is clamped. At this point, the assembly is completed. When the sliding member 8 moves, it drives the sliding frame 12 on the rear side to move backward, and the sliding frame 12 on the rear side drives the two auxiliary strips 13 on the rear side to move backward, thereby providing a moving space for the assembled joint 3, the oil pipe 15 and the pipe clamp 16. After that, the telescopic end of the second push rod 10 contracts to release the clamping of the oil pipe 15, and then the assembled joint 3, the oil pipe 15 and the pipe clamp 16 can be removed, and the auxiliary strip 13 is reset under the action of the torsion spring. Example
[0024] The automobile oil pipe clamp assembly device disclosed in this embodiment is capable of making the oil pipe 15 more evenly stretched on the basis of the first embodiment.
[0025] like Figure 3 and Figure 4 As shown, a main support rod 17 is fixedly connected to the right side of the auxiliary strip 13, so that the connection of the oil pipe 15 can be more evenly stretched.
[0026] like Figure 4As shown in the figure, two auxiliary struts 18 are slidably connected to the main strut 17. A first tension spring is arranged between the two auxiliary struts 18 on the same main strut 17. An air pump 19 is fixedly connected to the mounting bracket 6. The main strut 17 is communicated with the air pump 19 through a pipeline, and this pipeline passes through the auxiliary strip 13. The connection between the auxiliary strut 18 and the main strut 17 is not sealed. Therefore, when gas enters the main strut 17, the gas will leak out through the gap. However, the air supply speed of the air pump 19 is sufficient to keep the auxiliary strut 18 in the state of extending from the main strut 17.
[0027] Working process: When the oil pipe 15 sleeves the auxiliary strip 13, the main strut 17 and the auxiliary strut 18 are sleeved at the same time. At this time, the air pump 19 is started, and the air pump 19 supplies air into the four main struts 17 through the pipeline. The gas pushes the auxiliary strut 18 to move, so that the auxiliary strut 18 extends from the corresponding main strut 17. At the same time, the two auxiliary struts 18 on the same main strut 17 stretch the corresponding first tension spring, thereby increasing the contact area when the oil pipe 15 is expanded, making the expansion of the oil pipe 15 more uniform. When the auxiliary strip 13 is pulled out from between the oil pipe 15 and the joint 3, the main strut 17 is separated from the oil pipe 15. At this time, the air pump 19 is closed, and the adjacent two auxiliary struts 18 gradually reset under the action of the adjacent first tension spring, and squeeze the remaining gas in the adjacent main strut 17 to be discharged from the gap. Embodiment
[0028] An automobile oil pipe clamp assembly device disclosed in this embodiment is further improved on the basis of Embodiment 1.
[0029] As Figure 2 and Figure 5 shown in the figure, the sliding clamp 11 is slidably connected to the telescopic end of the second push rod 10, and a spring is arranged between them. The sliding clamp 11 is slidably connected to a limit block 20, and a second tension spring is arranged between the limit block 20 and the sliding clamp 11. A limit groove is arranged at the telescopic end of the second push rod 10, and the limit block 20 limits the sliding clamp 11 through the limit groove. The spring between the sliding clamp 11 and the second push rod 10 is initially in a compressed state, which is used to keep the relative position between the sliding clamp 11 and the telescopic end of the second push rod 10, so that when the sliding clamp 11 works normally, the limit groove of the second push rod 10 is aligned with the limit block 20.
[0030] As Figure 5As shown in the figure, the sliding clip 11 is slidably connected with an extrusion rod 21. The extrusion rod 21 and the fixed clip 9 are mutually extruded. There is damping between the extrusion rod 21 and the sliding clip 11, so that the extrusion rod 21 will not break away from the sliding clip 11 during normal operation. An inclined surface is provided on the upper side of the extrusion rod 21. The inclined surface of the extrusion rod 21 is mutually extruded with the limiting block 20. The elastic coefficient of the second tension spring between the limiting block 20 and the sliding clip 11 is less than the elastic coefficient of the spring between the sliding clip 11 and the telescopic end of the second push rod 10, so that when the extrusion rod 21 extrudes the limiting block 20 to move, the spring between the sliding clip 11 and the telescopic end of the second push rod 10 will not be compressed.
[0031] As Figure 5 shown, the length that the extrusion rod 21 extends out of the sliding clip 11 is less than 3 cm, which can refer to the maximum diameter of a human finger, so as to avoid the possibility that there is still a human finger between the fixed clip 9 and the sliding clip 11 after the extrusion rod 21 is triggered. The maximum relative sliding distance between the telescopic end of the second push rod 10 and the sliding clip 11 is greater than 3 cm, so that after the fixed clip 9 and the sliding clip 11 clamp the finger, even if the telescopic end of the second push rod 10 continues to extend, it will not directly push the sliding clip 11 to move further, so as to avoid injuring the human finger.
[0032] Working process: During the process that the fixed clip 9 and the sliding clip 11 clamp the oil pipe 15, if the finger of the staff accidentally gets between the fixed clip 9 and the sliding clip 11, at this time the sliding clip 11 first contacts the finger of the staff, and the sliding clip 11 stops moving due to the block of the finger. At this time, the telescopic end of the second push rod 10 continues to move downward and extrudes the adjacent spring, so that the finger of the staff will not be pinched. When there is no obstruction between the fixed clip 9 and the sliding clip 11, the sliding clip 11 drives the extrusion rod 21 to move until it contacts the fixed clip 9. At this time, the extrusion rod 21 stops moving, and the sliding clip 11 drives the limiting block 20 to continue to move downward. The limiting block 20 is extruded by the inclined surface of the extrusion rod 21 and moves leftward, and stretches the adjacent second tension spring. At the same time, the limiting block 20 is inserted into the limiting groove of the telescopic end of the second push rod 10, so as to lock the telescopic end of the second push rod 10 and the sliding clip 11, and avoid the sliding clip 11 from moving when the fixed clip 9 and the sliding clip 11 clamp the oil pipe 15 and are connected to the joint 3. Embodiment
[0033] An automobile oil pipe clip assembly device disclosed in this embodiment is further improved on the basis of Embodiment 1.
[0034] As Figure 5 shown, the fixed clip 9 is slidably connected with a support frame 22. The support frame 22 is used to support the oil pipe 15. The support frame 22 can freely expand and contract to adjust the extended length, so as to support the oil pipe 15 and avoid the oil pipe 15 from being bent under the action of gravity and unable to align with the joint 3. Embodiment
[0035] An automobile oil pipe clamp assembly device disclosed in this embodiment further defines the shapes of the main support rod 17 and the auxiliary support rod 18 on the basis of Embodiment 2, so that the main support rod 17 and the auxiliary support rod 18 fit more closely to the inner wall of the oil pipe 15.
[0036] As Figure 3 and Figure 5 shown, both the main support rod 17 and the auxiliary support rod 18 are arranged in an arc shape that fits the inner wall of the oil pipe 15, so that the connection part of the oil pipe 15 remains circular when it is expanded. Embodiment
[0037] An automobile oil pipe clamp assembly device disclosed in this embodiment further defines the positions of the main support rod 17 and the auxiliary support rod 18 on the basis of Embodiment 2, so that when the main support rod 17 and the auxiliary support rod 18 move outward from the oil pipe 15, they can scrape and restore to the original state the part of the oil pipe 15 that is buckled inward.
[0038] As Figure 3 and Figure 5 shown, the four main support rods 17 are respectively located on the back sides of the four auxiliary bars 13, so that when the main support rod 17 and the auxiliary support rod 18 move, they can buckle the part of the oil pipe 15 that is buckled inward, and thus restore the part of the oil pipe 15 that is buckled inward to the original state.
[0039] The above has described in detail the embodiments of the present invention in conjunction with the accompanying drawings. However, the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the scope of knowledge possessed by those skilled in the art.
