[0059] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
[0060] like Figures 1 to 8As shown, the utility model is an automatic assembly and oiling equipment for a car headrest frame, which is used to assemble the headrest support rod 1 into the sliding seat 2 with a mounting hole 20, wherein the equipment includes: a frame 4, which is equipped with a tooling plate 40; a positioning mechanism 5, which is arranged on the tooling plate 40, and the positioning mechanism 5 is used to position and clamp the sliding seat 2 to be assembled; a sliding mechanism 6, which is arranged on the tooling plate 40 and is located on one side of the positioning mechanism 5, and a moving plate 60 is movably provided on the sliding mechanism 6, and a fixing member 61 is installed on the moving plate 60, and the fixing member 61 is used to fix the headrest support rod 1 to be assembled on the moving plate 60, so that the moving plate 60 can drive the headrest support rod 1 to be assembled closer to or farther away from the positioning mechanism 5; a guide mechanism 7 and a pressing mechanism 8, which are movably provided on the side of the positioning mechanism 5 away from the sliding mechanism 6, and the guide mechanism 7 is used to set the transverse block 3 placed at its top to the same height as the sliding seat 2; a pressing block 80 is movably provided on the pressing mechanism 8, and the pressing block 80 is movably provided Dynamically pressurized on the transverse block 3, so that the headrest support rod 1 can pass through the sliding seat 2 and be connected to the transverse block 3; the oiling mechanism 9 is movably arranged on the tooling plate 40 and is located between the positioning mechanism 5 and the sliding mechanism 6. The oiling mechanism 9 is provided with an oiling cylinder 90, and the driving end of the oiling cylinder 90 is connected to the first clamping block 91 and the second clamping block 92. The first clamping block 91 and the second clamping block 92 are both provided with a plurality of mutually connected oiling holes 93, and the oiling holes 93 can be connected to the outside. The oil delivery pipe is used for oiling the headrest support rod 1 through the oiling hole 93 when the first clamping block 91 and the second clamping block 92 approach each other; before assembly, the oiling mechanism 9 can drive the oiling cylinder 90 to pass through the tooling plate 40 and extend to both sides of the headrest support rod 1, so that the first clamping block 91 and the second clamping block 92 can complete the clamping and oiling operation; and after the oiling is completed, it drives the oiling cylinder 90 to retract to the bottom of the tooling plate 40, so that the headrest support rod 1 and the sliding seat 2 can be assembled.
[0061] In this embodiment, the automobile headrest frame is composed of a transverse block 3, a sliding seat 2 and a headrest support rod 1. During the assembly process of the automobile headrest frame, it is necessary to manually pass the headrest support rod 1 through the sliding seat 2 and connect it to the transverse block 3, and a manual oiling process is mixed in the assembly steps. This operation method seriously increases the labor intensity. Therefore, this solution provides an automatic assembly and oiling process for the headrest frame. Specifically, Figures 1 to 8As shown, when the sliding seat 2 to be assembled is fixed by the positioning mechanism 5, the headrest support rod 1 to be assembled is accurately and stably positioned by the fixing piece 61 on the material shifting plate 60, and the position of the guide mechanism 7 is adjusted in the vertical direction so that the transverse block 3 at its top is flush with the sliding seat 2, the pre-assembly process is ready. In addition, the present solution is provided with a retractable oiling mechanism 9 between the sliding mechanism 6 and the positioning mechanism 5. That is to say, before the above-mentioned assembly step is started, the oiling cylinder 90 is lifted to the side of the headrest support rod 1 to be assembled by the oiling mechanism 9. As the oiling mechanism 9 drives the first clamping block 91 and the second clamping block 92 to clamp the headrest support rod 1 to be assembled, The oiling hole 93 connected to the external oil pipeline can be used to evenly apply oil on the headrest support rod 1. This oiling process replaces the manual oiling step, reduces human fatigue intensity, and also ensures the assembly quality and efficiency between the headrest support rod 1 and the sliding seat 2. It is worth noting that after the oiling process of the headrest support rod 1 is completed, the oiling mechanism 9 can drive the oiling cylinder 90 to retract to the bottom of the tooling plate 40 to ensure the smoothness and stability of the subsequent material shifting plate 60 when driving the headrest support rod 1 to approach the sliding seat 2 and the transverse block 3 for assembly operation, effectively avoiding the position interference between the oiling mechanism 9 and the sliding mechanism 6 during the assembly process, which affects the accuracy of the final assembly.
[0062] The oiling mechanism 9 also includes: a mounting plate 94, which is arranged at the bottom of the tooling plate 40, and a lifting cylinder 95 is arranged on the mounting plate 94; a lifting plate 96 arranged in a U-shape, the bottom of the lifting plate 96 is connected to the driving end of the lifting cylinder 95, and the top is connected to the oiling cylinder 90, so that when the lifting plate 96 passes through the tooling plate 40, the oiling cylinders 90 at both ends can be placed on both sides of the headrest support rod 1 respectively; a fixing plate 97, which is connected to the bottom of the lifting cylinder 95, and a guide sleeve 970 is installed on the fixing plate 97, and a guide column 960 is connected to the lifting plate 96, and the guide column 960 is movably inserted in the guide sleeve 970; a position sensor 98, which is arranged on the lifting plate 96, and the position sensor 98 can move synchronously with the lifting plate 96 in the vertical direction to detect the position of the lifting plate 96 relative to the tooling plate 40.
[0063] like Figure 1 、 Figure 2 、 Figure 4 as well as Figure 5As shown, the lifting cylinder 95 is fixed to the bottom of the tooling plate 40 by means of the mounting plate 94. Since the driving end of the lifting cylinder 95 is arranged to face upward in the vertical direction, the lifting plate 96 can be driven to move upward by the driving of the lifting cylinder 95, and finally the oiling cylinder 90 is moved to one side of the headrest support rod 1 to be assembled to ensure the subsequent clamping and oiling process. It should be noted that the lifting plate 96 in this scheme is U-shaped, that is, the two oiling cylinders 90 in this embodiment are respectively mounted on the top of the two ends of the lifting plate 96. With one lifting action of the lifting cylinder 95, the two oiling cylinders 90 can be synchronously moved to the two sides of the headrest support rod 1 through the lifting plate 96, which has good stability and improves work efficiency. Preferably, in the process of driving the lifting plate 96 to move by the lifting cylinder 95, the guide column 960 is movably inserted in the guide sleeve 970, which has a certain guiding and limiting effect on the movement of the lifting plate 96 in the vertical direction.
[0064] Preferably, the present solution also provides a position sensor 98 on the lifting plate 96. As the lifting plate 96 moves in the vertical direction, the position of the lifting plate 96 after lifting can be detected by the position sensor 98 to ensure that the oiling cylinder 90 can accurately move to the side of the headrest support rod 1 to be assembled, which provides a guarantee for the smoothness and stability of the subsequent oiling cylinder 90 driving the first clamping block 91 and the second clamping block 92 to implement the oiling process; in addition, the oiling cylinder 90 can adopt a rotating cylinder. After the oiling operation is completed, the rotating cylinder is used to rotate to a posture placed in the vertical direction to ensure that the lifting cylinder 95 can smoothly retract the oiling cylinder 90 to the bottom of the tooling plate 40.
[0065] The oiling hole 93 includes a main hole 930 and several diversion holes 931. An arc-shaped clamping surface 910 is formed on the first clamping block 91 and the second clamping block 92. One end of the several diversion holes 931 is connected to the arc-shaped clamping surface 910, and the other end is connected to the main hole 930.
[0066] Further, if Figure 5 As shown, the main flow hole 930 is used to connect and fix with the external oil pipeline. As the first clamping block 91 and the second clamping block 92 approach each other and are clamped on the outer wall of the headrest support rod 1 to be assembled, the oil pipeline can be used to flow the oil through the main flow hole 930 into the plurality of branch holes 931, and the arc-shaped clamping surface 910 is used to evenly disperse the oil to the outer surface of the headrest support rod 1 to be assembled, which effectively saves the manual oiling operation steps and improves the overall assembly efficiency of the automobile headrest frame.
[0067] The fixing part 61 includes: a plurality of fixing blocks 610, which are distributed on the material moving plate 60, and a fixing groove 610a is formed on the fixing block 610, and the headrest support rod 1 to be assembled is placed in the fixing groove 610a; a clamping cylinder 611, the bottom of the tooling plate 40 is connected to the extension block 400, and the driving end of the clamping cylinder 611 is vertically downward and connected to the extension block 400; a support block 612 and a flip block 613, the support block 612 is set on the tooling plate 40, and a connecting block 612a is hinged on the support block 612, and the connecting block 612a is hinged to the flip block 613; the side wall of the clamping cylinder 611 is connected to the mounting block 611a, one end of the flip block 613 is connected to the clamping column 614, and the other end is hinged to the mounting block 611a.
[0068] like Figure 2 and Figure 3 As shown, the positioning of the headrest support rod 1 to be assembled determines the accuracy of the subsequent assembly. Therefore, after the worker or the robot places the headrest support rod 1 to be assembled into the fixing groove 610a, the pre-positioning of the headrest support rod 1 is achieved. It is worth noting that the driving end of the clamping cylinder 611 in this scheme is fixed on the extension block 400. As the driving end of the clamping cylinder 611 is driven, its cylinder body is displaced in the vertical direction, thereby driving the mounting block 611a to move synchronously, so that the flip block 613 can rotate around the connecting block 612a hinged on the support block 612, and finally the clamping column 614 at the end of the flip block 613 is close to and pressed against the top wall of the headrest support rod 1. The structure is relatively simple as a whole, and the operation is convenient and quick. At the same time, the space occupied by the overall components is saved to a certain extent.
[0069] The sliding mechanism 6 also includes: a symmetrically arranged assembly cylinder 62, which is connected to the bottom of the tooling plate 40, and a driving block 620 is provided at the driving end of the assembly cylinder 62. A guide hole 401 is provided on the tooling plate 40, and the driving block 620 passes through the guide hole 401 and is connected to the bottom of the material moving plate 60; a guide rail 63 and a guide block 64, the guide rail 63 is arranged on the tooling plate 40 and faces the positioning mechanism 5, the guide block 64 is connected to the bottom of the material moving plate 60, and is movably clamped on the guide rail 63; a buffer block 65 and a limit block 66, which are respectively arranged at the two end portions of the guide rail 63 in the length direction. The material moving plate 60 can be movably abutted against the buffer block 65 during assembly to reduce the impact force generated when the headrest support rod 1 and the sliding seat 2 are assembled; and it can be movably abutted against the limit block 66 during resetting to limit the moving distance of the material moving plate 60.
[0070] like Figure 2 and Figure 3As shown, when the headrest support rod 1 to be assembled is positioned and the oiling process is carried out normally, the driving block 620 can be pushed to move by the assembly cylinder 62, thereby driving the moving plate 60 to approach the sliding seat 2 in the above-mentioned positioning mechanism 5 for assembly operation. During this process, the driving block 620 moves along the length direction of the guide hole 401, playing a certain guiding and limiting effect, ensuring that the headrest support rod 1 can be accurately and movably inserted into the sliding seat 2. At the same time, the moving plate 60 relies on the guide block 64 to be movably engaged with the guide rail 63, further improving the smoothness and stability of the moving plate 60 when the headrest support rod 1 moves. When the moving plate 60 approaches the positioning mechanism 5, the moving plate 60 can be movably pressed against the buffer block 65 to have a certain buffering effect on the assembly rate during the assembly process, avoiding the headrest support rod 1 from colliding with the sliding seat 2 and causing damage. At the same time, the limiting block 66 effectively limits the moving distance of the moving plate 60, ensuring that the headrest support rod 1 to be assembled is not affected by other components during positioning and placement.
[0071] Preferably, if Figure 3 As shown, the present solution further provides an anti-slip block 67 on the material shifting plate 60, and the anti-slip block 67 is located on one side of the fixed block 610 and is pressed against the end of the headrest support rod 1. During the placement of the headrest support rod 1 to be assembled, the anti-slip block 67 can be used to pre-position the position of the headrest support rod 1. During the assembly of the headrest support rod 1 and the sliding seat 2, the anti-slip block 67 can effectively prevent the headrest support rod 1 from being displaced relative to the fixed groove 610a during assembly, thereby affecting the smoothness and accuracy of the assembly.
[0072] The positioning mechanism 5 includes: a profiling block 50, which is arranged on the tooling plate 40, and a clearance groove 500 and a profiling groove 501 are formed on the profiling block 50. The end of the guide rail 63 extends into the clearance groove 500 to allow the headrest support rod 1 and the sliding seat 2 to be accurately assembled; the sliding seat 2 is placed in the profiling groove 501 to limit the displacement of the sliding seat 2; a driving member 51, which is arranged on one side of the profiling block 50, and the driving end of the driving member 51 is hinged with a clamping plate 510, which is used to movably press the sliding seat 2 into the profiling groove 501.
[0073] like Figure 1 and Figure 6As shown, this solution utilizes the contoured groove 501 on the contoured block 50 to position the sliding seat 2 to be assembled. As the driver 51 drives the pressing plate 510 to move and press against the top wall of the sliding seat 2, this ensures that the sliding seat 2 maintains a certain degree of stability during assembly. A clearance groove 500 is also formed at the bottom of the contoured block 50. Notably, the end of the guide rail 63 extends partially into the clearance groove 500. This design effectively ensures that the shifting plate 60 has sufficient displacement space to accurately pass the headrest support rod 1 through the sliding seat 2 and connect to the transverse block 3, avoiding positional interference that could affect the accuracy of the overall assembly of the vehicle headrest frame.
[0074] Preferably, the present solution further provides an assembly detector 52 on the inner wall of the give way groove 500 on the profiling block 50. When the above-mentioned shifting plate 60 drives the headrest support rod 1 to pass through the sliding seat 2 and connects the transverse block 3, the assembly detector 52 can be used to detect the distance of the headrest support rod 1 that is movably inserted in the sliding seat 2, thereby ensuring the accuracy of the assembly position of the headrest support rod 1 and avoiding damage to parts caused by the shifting plate 60 continuing to drive the headrest support rod 1 to move after the assembly is in place.
[0075] The guide mechanism 7 includes: a mounting frame 70, which is arranged at the bottom of the tooling plate 40, and a positioning cylinder 71 is provided on the mounting frame 70. The driving end of the positioning cylinder 71 passes through the tooling plate 40 and moves on one side of the profiling block 50; a positioning seat 72, which is connected to the driving end of the positioning cylinder 71, and a positioning groove 720 is provided on the positioning seat 72. The positioning groove 720 is used to position the transverse block 3 on one side of the profiling block 50, so that the connecting hole 30 on the transverse block 3 can be placed coaxially with the mounting hole 20.
[0076] like Figure 2 and Figure 7 As shown, the positioning cylinder 71 in this embodiment is mainly used to realize the position adjustment of the positioning seat 72 relative to the above-mentioned profiling block 50. Because of this, it is effectively guaranteed that the transverse block 3 placed in the positioning groove 720 can be placed at the same height as the sliding seat 2 in the profiling groove 501. It should be noted that this structure can also adopt the above-mentioned guide column 960 to movably insert the guide sleeve 970 to ensure that the transverse block 3 in the positioning seat 72 is in a horizontal position, so that the connecting hole 30 on the transverse block 3 can be placed coaxially with the mounting hole 20 in the sliding seat 2, which provides a guarantee for the smoothness and accuracy of the subsequent headrest support rod 1 when it moves with the material transfer plate 60.
[0077] The clamping mechanism 8 includes: a base plate 81, which is arranged on the tooling plate 40, and a first mounting seat 810 and a second mounting seat 811 are symmetrically arranged on the base plate 81, and the second mounting seat 811 is close to the positioning seat 72; a locking cylinder 82, which is arranged at the bottom of the tooling plate 40, and a clearance hole 812 is provided in the middle position of the base plate 81, and the driving end of the locking cylinder 82 passes through the clearance hole 812 and is connected to the receiving block 820, and a connecting shaft 821 is provided in the receiving block 820; a first connecting rod 83, one end of which is hinged to the first mounting seat 810, and the other end is hinged to the connecting shaft 821; the bottom end of the clamping block 80 is hinged to the second mounting seat 811, and the top end is movably hinged to the second connecting rod 84, and the end of the second connecting rod 84 is hinged to the connecting shaft 821; the first connecting rod 83 and the second connecting rod 84 can be in the same straight line when the locking cylinder 82 is lifted, so that the clamping block 80 can be movably pressed against the top wall of the transverse block 3.
[0078] In addition to the positioning and pressing of the fixing member 61, the profiling block 50 and the positioning seat 72, this solution also uses a pressing block 80 to press the top wall of the transverse block 3. The difference is that when the locking cylinder 82 drives the receiving block 820 to be in the Figure 8 In the state shown, the dead point phenomenon that occurs when the first connecting rod 83 and the second connecting rod 84 are in the same straight line can be utilized to ensure the stability of the pressing block 80 when pressing the top wall of the transverse block 3 to a great extent, thereby providing a guarantee for the subsequent assembly accuracy. Figure 8 When moving downward, the first connecting rod 83 can rotate around the first mounting seat 810 under the traction of the receiving block 820, and the second connecting rod 84 pulls the pressing block 80 away from the transverse block 3 during the rotation, so as to facilitate the disassembly of the transverse block 3 after assembly is completed.
[0079] It should be noted that the driving member 51 in this solution can be replaced by other driving devices such as hydraulic drive, cylinder drive, etc.
[0080] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.
[0081] In addition, terms such as "first," "second," and "an" in this utility model are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features indicated. Therefore, features specified as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of this utility model, "plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

For example, "fixation" can mean fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.
[0083] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in this field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this utility model.
