Description

Technical Field

[0001] The invention relates to the technical field of door closer production, and in particular to a heavy-duty ultra-thin door closer assembly machine and an assembly method. Background Art

[0002] The door closer is a spring-like hydraulic device on the door head. When the door is opened, it can be compressed and then released to automatically close the door. It acts like a spring door and can ensure that the door is accurately and promptly closed to the initial position after being opened. The basic structure of the door closer host mainly includes the door closer body, the gear transmission shaft arranged in the seat body, the rack plunger, the return spring, the one-way valve and the support and guide assembly arranged on the door closer body and matched with the gear transmission shaft, as well as the throttle valve core, the end cover, the sealing ring and other components. The support and guide assembly plays a role in supporting the rotation of the gear transmission shaft.

[0003] At present, the end cover is threadedly connected to the door closer body, and the end cover needs to be screwed into the end of the door closer. For some models of door closers, end covers are provided at both ends or both sides. When there is only one end cover, the shell can be fully engaged and then the workers can install the end cover. However, when end covers are provided at both ends of the shell, it is difficult to assemble them at the same time, and the assembly efficiency is low.

[0004] In view of the above technical problems, the applicant has retrieved some prior art to realize the threaded connection assembly of two sets of end caps at the same time. For example, the patent publication number is CN115041935B. Its main technical means is to drive the shell conveying turntable and the end cap conveying turntable to rotate, use the shell slot to transport the shell, and use the end cap slot to transport the end cap. When the shell slot and the end cap slot coincide with each other at the assembly station, the spinning plate passes through the two end cap slots and rotates to push the end cap toward the shell, so that the threaded connection assembly of the two sets of end caps can be realized at the same time. After analysis by the applicant, the disadvantages of this technical solution are: During the rotation of the turntable, although the end cap can be effectively transported from the loading point to the assembly station, the position of the end cap in the end cap slot is unstable. Due to the centrifugal force generated by the rotation, the end cap will move in the slot. As a result, when the end cap slot is moved to the assembly station, it is impossible to ensure that the end cap is accurately aligned with the end cap mounting groove on the door closer shell. Once misalignment occurs, the threaded connection between the end cap and the shell cannot proceed smoothly, and subsequent manual adjustment is required to complete the installation. Based on this, the present invention purposely provides a heavy-duty ultra-thin door closer assembly machine and assembly method, which can ensure that the end cap is accurately aligned with the mounting groove of the door closer shell during assembly. Summary of the invention

[0005] The purpose of the present invention is to provide a heavy-duty ultra-thin door closer assembly machine and an assembly method in view of the deficiencies in the prior art, so as to solve the technical problems in the prior art.

[0006] The purpose of the present invention can be achieved through the following technical solutions: A heavy-duty ultra-thin door closer assembly machine, comprising: A base, on which two symmetrically arranged outer turntables are rotatably mounted, one of the outer turntables being driven to rotate by a first output source, an inner turntable being coaxially fixedly mounted between the two outer turntables, each outer turntable being provided with a plurality of circumferentially arranged outer grooves, and a loading assembly being provided above each outer turntable, the loading assembly being used to transport the end caps to the outer grooves, the inner turntable being provided with a plurality of circumferentially arranged inner grooves, each inner groove having an outer groove aligned therewith at both ends, the base being provided with two symmetrically arranged assembly assemblies, an assembly station being formed between the two assembly assemblies, and the base being provided with a telescopic member for pushing the door closer housing into the inner groove, the assembly assembly rotatingly pushing the end caps into the mounting grooves on the door closer housing for assembly; There are multiple round rods, the multiple round rods form a semicircle, and multiple round rods are arranged in each outer groove; There are multiple rotating rods, and the multiple rotating rods are rotatably installed on the outer turntable. The rotating rods are driven to rotate by the second output source. Each outer groove corresponds to a rotating rod. A sliding rod is slidably inserted on each rotating rod, and a sleeve is sleeved on the sliding rod. When the loading assembly conveys the end cover to the outer groove, the end cover falls onto multiple round rods, and the second output source drives the rotating rod to rotate so that the sleeve abuts the end cover. At this time, the axis of the end cover is at a first distance from the axis of the outer turntable, and the first distance is constant. When the door closer shell is located in the inner groove, the axis of the mounting groove on the door closer shell is at a second distance from the axis of the inner turntable, and the second distance is equal to the first distance.

[0007] As a further solution of the present invention: the plurality of round rods are rotatably mounted on the outer groove, and the sleeve is rotatably connected to the slide rod.

[0008] As a further solution of the present invention: the feeding assembly includes a feed barrel, a first plug-in sheet, a second plug-in sheet, a linkage assembly and a driving assembly. The feed barrel is arranged above the outer turntable, and a plurality of end covers are stacked in sequence from bottom to top inside the feed barrel. The first plug-in sheet and the second plug-in sheet are both slidably installed on the feed barrel, and the second plug-in sheet is located above the first plug-in sheet, and the two are alternately inserted in the feed barrel, and the first plug-in sheet drives the second plug-in sheet to move through the linkage assembly. The distance between the second plug-in sheet and the first plug-in sheet located in the feed barrel is consistent with the diameter of an end cover. When the outer groove and the feed barrel are aligned, the second output source drives the rotating rod to rotate so that the sleeve moves away from the outer groove. At this time, the rotation of the rotating rod drives the first plug-in sheet to move out of the feed barrel through the driving assembly.

[0009] As a further solution of the present invention: the linkage assembly includes a fixed frame, an active rack plate, a driven rack plate and a gear; the fixed frame is fixedly mounted on the feed barrel; the active rack plate and the driven rack plate are both slidably mounted in the fixed frame; the driven rack plate is fixedly connected to the second plug-in piece; the active rack plate is fixedly connected to the first plug-in piece; the gear is rotatably mounted on the feed barrel and is located between the active rack plate and the driven rack plate; the gear is meshed with the active rack plate and with the driven rack plate; when the rotating rod rotates to make the sleeve move away from the outer groove, the rotating rod drives the active rack plate away from the feed barrel through the driving assembly.

[0010] As a further solution of the present invention: the driving assembly includes an extension plate, a second spring and a passing groove, the extension plate is fixedly mounted on the active rack plate, the active rack plate is connected to the fixed frame through the second spring, the pre-tightening force of the second spring makes the active rack plate close to the feed barrel, the passing groove is opened on the feed barrel, when the rotating rod rotates to make the sleeve move away from the outer groove, the sleeve passes through the passing groove, and the rotating rod abuts and pushes the extension plate away from the feed barrel.

[0011] As a further solution of the present invention: after the assembly component assembles the end cover and the door closer housing, the sleeve abuts against a portion of the end cover protruding from the door closer housing.

[0012] As a further solution of the present invention: a conveyor belt is arranged below the outer turntable and the inner turntable, and two symmetrically arranged electromagnets are fixedly installed on the conveyor belt, and a feeding station is formed between the two. The slide bar is connected to the rotating rod through a first spring, and the pre-tightening force of the first spring makes the slide bar move away from the rotating rod. An iron block is fixedly installed on one end of the slide bar that passes through the rotating rod, and the iron block abuts against the rotating rod. When the assembled end cover and the door closer housing move to the feeding station, the electromagnet attracts the iron block, so that the slide bar compresses the first spring, and the sleeve is away from the end cover.

[0013] A heavy-duty ultra-thin door closer assembly method, the method is applied to a heavy-duty ultra-thin door closer assembly machine as described above, the method comprising the following steps: Step S1: driving the outer turntable and the inner turntable to rotate synchronously through the first output source, so that the outer groove on the outer turntable rotates to the bottom of the loading assembly, and the loading assembly conveys the end cap to the outer groove; Step S2: the end cap then falls onto the multiple round rods in the outer groove, and the second output source drives the rotating rod to rotate, so that the sleeve abuts against the end cap, thereby clamping the end cap; Step S3: Then the first output source drives the outer turntable and the inner turntable to rotate synchronously, so that the end cover rotates to the assembly station; Step S4: placing the door closer housing on the base and pushing it into the inner groove through the telescopic member, at which point the door closer housing is located between the two end covers, and the axis of the mounting groove on the door closer housing coincides with the axis of the end cover; Step S5: The end cover is rotated and pushed into the mounting groove on the door closer housing by assembling the components, thereby completing the assembly.

[0014] Beneficial effects of the present invention: 1. In the present invention, after the unloading assembly conveys the end cover to the outer groove, the end cover falls onto the multiple round rods in the outer groove. At this time, the sleeve abuts against the end cover by rotating the rotating rod, thereby clamping the end cover to ensure that the end cover cannot move. Subsequently, the outer turntable and the inner turntable rotate to move the end cover to the assembly station, and then the door closer housing is placed in the inner groove. At this time, the axis of the mounting groove on the door closer housing coincides with the axis of the end cover. The end cover and the door closer housing can be assembled through the assembly assembly. At this time, the end cover moves along the sleeve and the round rod, avoiding the problem of misalignment between the axis of the end cover and the axis of the mounting groove of the door closer housing when the end cover is moved from the loading position to the assembly station due to the end cover being movable in the outer groove. Therefore, there is no need to manually adjust the position of the end cover and the door closer housing for a second time, thereby improving the efficiency of successful assembly. 2. In the present invention, since the end cover is rotated and pushed into the installation groove, it means that the end cover is rotated to move out of the end cover and the sleeve, and the round rod and the sleeve are both arranged to be rotatable. In this way, when the end cover rotates, the friction between the end cover and the round rod will drive the round rod to rotate, and the friction between the end cover and the sleeve will also drive the sleeve to rotate, thereby converting the sliding friction into rolling friction, thereby reducing the friction resistance of the end cover during the process of being rotated and pushed in, and facilitating the assembly; 3. In the present invention, when loading the end cover into the outer groove, it is necessary to ensure that there is no obstruction between the feed barrel and the outer groove. Therefore, it is necessary to drive the rotating rod to rotate through a second output source so that the sleeve is away from the outer groove. After the rotating rod rotates, the driving component and the linkage component will be used to allow an end cover in the feed barrel to be loaded into the outer groove. Then the rotating rod is rotated and reset so that the sleeve abuts the end cover in the outer groove. In this process, the driving component and the linkage component will cause the stacked end covers in the feed barrel to drop, and the vacant position after loading will be filled up again, thereby preparing for the next loading.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] See also Figure 1-Figure 9 As shown, the present invention is a heavy-duty ultra-thin door closer assembly machine, comprising: A base 1 is provided on which two symmetrically arranged outer turntables 2 are rotatably mounted, one of the outer turntables 2 being driven to rotate by a first output source, an inner turntable 3 being coaxially fixedly mounted between the two outer turntables 2, each of the outer turntables 2 being provided with a plurality of circumferentially arranged outer grooves 4, and a loading assembly being provided above each of the outer turntables 2, the loading assembly being used to transport the end cap 7 to the outer groove 4, the inner turntable 3 being provided with a plurality of circumferentially arranged inner grooves 5, each of the inner grooves 5 having an outer groove 4 aligned therewith at both ends, the base 1 being provided with two symmetrically arranged assembly assemblies 8, an assembly station being formed between the two assembly assemblies 8, and the base 1 being provided with a telescopic member 9 for pushing the door closer housing 6 into the inner groove 5, the assembly assembly 8 rotatingly pushes the end cap 7 into the mounting groove on the door closer housing 6 for assembly; There are multiple round rods 10, which form a semicircle. Multiple round rods 10 are arranged in each outer groove 4; There are multiple rotating rods 13, and multiple rotating rods 13 are rotatably installed on the outer turntable 2. The rotating rods 13 are driven to rotate by the second output source. Each outer groove 4 corresponds to a rotating rod 13. A sliding rod 11 is slidably inserted on each rotating rod 13, and a sleeve 12 is sleeved on the sliding rod 11. When the feeding assembly conveys the end cover 7 to the outer groove 4, the end cover 7 falls onto multiple round rods 10, and the second output source drives the rotating rod 13 to rotate so that the sleeve 12 abuts the end cover 7. At this time, the axis of the end cover 7 is at a first distance from the axis of the outer turntable 2, and the first distance is constant. When the door closer housing 6 is located in the inner groove 5, the axis of the mounting groove on the door closer housing 6 is at a second distance from the axis of the inner turntable 3, and the second distance is equal to the first distance.

[0020] In one case of the present embodiment, the first output source and the second output source can both be selected from components such as servo motors and reciprocating motors, and other mechanisms capable of realizing rotational motion can also be selected. The present embodiment is not specifically limited here. It should be noted that the assembly component 8 described in the present invention includes a pressure plate, a servo motor, a reciprocating cylinder, etc. The above components are all prior arts, and the present invention does not improve them. Therefore, there is no need to disclose their specific mechanical structure and circuit structure, which does not affect the integrity of the present invention.

[0021] The working principle of the present invention is as follows: the outer turntable 2 and the inner turntable 3 are driven to rotate synchronously by the first output source, so that the outer groove 4 on the outer turntable 2 rotates to the bottom of the feeding assembly, and the feeding assembly conveys the end cover 7 to the outer groove 4, and then the end cover 7 falls onto a plurality of round rods 10 in the outer groove 4, and the second output source drives the rotating rod 13 to rotate so that the sleeve 12 abuts against the end cover 7, thereby clamping the end cover 7. At this time, the distance between the axis of the end cover 7 and the axis of the outer turntable 2 is the first distance, and the first distance is constant, which means that the position of the end cover 7 is constant, and then the first output source drives the outer turntable 2 and the inner turntable 3 to rotate synchronously, so that the end cover 7 rotates to the assembly At the installation station, the door closer housing 6 is placed on the base 1 and pushed into the inner groove 5 through the telescopic member 9. At this time, the door closer housing 6 is located between the two end covers 7. The distance between the axis of the mounting groove on the door closer housing 6 and the axis of the inner turntable 3 is the second distance, and the second distance is equal to the first distance, which means that the axis of the end cover 7 coincides with the axis of the mounting groove on the door closer housing 6. The sleeve 12 and the round rod 10 limit the end cover 7, ensuring that the end cover 7 will not move in the outer groove 4 when it is moved from the loading assembly to the assembly station, thereby avoiding the problem of the axis of the end cover 7 and the axis of the mounting groove on the door closer housing 6 being offset. Subsequently, the end cover 7 is rotated and pushed into the mounting groove on the door closer housing 6 through the assembly component 8, thereby completing the assembly of the door closer housing 6 and the door closer housing 6, and in the process of the end cover 7 being rotated and pushed in, the sleeve 12 and the round rod 10 guide the direction of movement of the end cover 7 to ensure that the end cover 7 can be accurately inserted into the mounting groove, and when the end cover 7 and the door closer housing 6 are threadedly connected, since the door closer housing 6 is abutted against the inner wall of the inner groove 5 by the telescopic part 9, the position of the door closer housing 6 is fixed, and at the same time, the other outer groove 4 on the outer turntable 2 is moved to the bottom of the unloading component, so that loading can be carried out during assembly, thereby improving the overall assembly efficiency.

[0022] like Figure 3 As shown, as a preferred embodiment of the present invention, the plurality of round rods 10 are rotatably mounted on the outer groove 4 , and the sleeve 12 is rotatably connected to the slide rod 11 .

[0023] In actual application of this embodiment, since the end cover 7 is rotated and pushed into the installation groove, this means that the end cover 7 is rotated to move out of the end cover 7 and the sleeve 12, and the round rod 10 and the sleeve 12 are both set to be rotatable. In this way, when the end cover 7 rotates, the friction between the end cover 7 and the round rod 10 will drive the round rod 10 to rotate, and the friction between the end cover 7 and the sleeve 12 will also drive the sleeve 12 to rotate, thereby converting the sliding friction into rolling friction, thereby reducing the friction resistance encountered by the end cover 7 during the process of being rotated and pushed in, and facilitating assembly.

[0024] like Figure 1-Figure 7 As shown, as a preferred embodiment of the present invention, the feeding assembly includes a feed barrel 18, a first plug-in piece 20, a second plug-in piece 21, a linkage assembly and a drive assembly. The feed barrel 18 is arranged above the outer turntable 2, and a plurality of end covers 7 are stacked in sequence from bottom to top inside the feed barrel 18. The first plug-in piece 20 and the second plug-in piece 21 are both slidably mounted on the feed barrel 18, and the second plug-in piece 21 is located above the first plug-in piece 20, and the two are alternately inserted in the feed barrel 18, and the first plug-in piece 20 drives the second plug-in piece 21 to move through the linkage assembly. The distance between the second plug-in piece 21 and the first plug-in piece 20 located in the feed barrel 18 is consistent with the diameter of one end cover 7. When the outer groove 4 and the feed barrel 18 are aligned, the second output source drives the rotating rod 13 to rotate so that the sleeve 12 moves away from the outer groove 4. At this time, the rotating rod 13 rotates to drive the first plug-in piece 20 to move out of the feed barrel 18 through the drive assembly.

[0025] In practical application, if Figure 6Taking the example shown, since the first plug-in sheet 20 and the second plug-in sheet 21 are alternately inserted into the feeding barrel 18, when the first plug-in sheet 20 is moved out of the feeding barrel 18, the second plug-in sheet 21 will gradually be inserted into the feeding barrel 18. At this time, the second plug-in sheet 21 will gradually separate the two stacked end caps 7, and finally let the end cap 7 between the first plug-in sheet 20 and the second plug-in sheet 21 fall, and the second plug-in sheet 21 will intercept the end cap 7 above it. After the unloading is completed, the first plug-in sheet 20 is inserted back into the feeding barrel 18, so that an end cap 7 appears between the first plug-in sheet 20 and the second plug-in sheet 21 again, preparing for the next unloading. In this way, it is ensured that one end cap 7 is unloaded each time, and the synchronous movement of the first plug-in sheet 20 and the second plug-in sheet 21 shortens the time of a single unloading, and there is no need to separate an end cap 7 before unloading.

[0026] like Figure 1-Figure 7 As shown, as a preferred embodiment of the present invention, the linkage assembly includes a fixed frame 19, an active rack plate 22, a driven rack plate 23 and a gear 24. The fixed frame 19 is fixedly installed on the feed barrel 18. The active rack plate 22 and the driven rack plate 23 are both slidably installed in the fixed frame 19. The driven rack plate 23 is fixedly connected to the second plug-in piece 21, and the active rack plate 22 is fixedly connected to the first plug-in piece 20. The gear 24 is rotatably installed on the feed barrel 18 and is located between the active rack plate 22 and the driven rack plate 23. The gear 24 is meshed with the active rack plate 22 and the driven rack plate 23. When the rotating rod 13 rotates to make the sleeve 12 move away from the outer groove 4, the rotating rod 13 drives the active rack plate 22 away from the feed barrel 18 through the driving assembly.

[0027] In actual application of this embodiment, when the active rack plate 22 is away from the feeding barrel 18, the active rack plate 22 will drive the first plug-in piece 20 to move out of the feeding barrel 18, and the active rack plate 22 will drive the gear 24 to rotate, and the gear 24 will drive the driven rack plate 23 to slide, and the moving direction of the driven rack plate 23 is opposite to that of the active rack plate 22, so the driven rack plate 23 will approach the feeding barrel 18, and the driven rack plate 23 will drive the second plug-in piece 21 to be inserted into the feeding barrel 18, so that the synchronous movement of the first plug-in piece 20 and the second plug-in piece 21 can be ensured, thereby shortening the time of a single unloading end cover 7.

[0028] like Figure 1-Figure 7As shown, as a preferred embodiment of the present invention, the driving assembly includes an extension plate 25, a second spring 26 and a through slot 27. The extension plate 25 is fixedly mounted on the active rack plate 22. The active rack plate 22 is connected to the fixed frame 19 through the second spring 26. The preload force of the second spring 26 makes the active rack plate 22 close to the feed barrel 18. The through slot 27 is opened on the feed barrel 18. When the rotating rod 13 rotates to make the sleeve 12 move away from the outer groove 4, the sleeve 12 passes through the through slot 27, and the rotating rod 13 abuts and pushes the extension plate 25 away from the feed barrel 18.

[0029] In actual application of this embodiment, when the outer groove 4 and the feeding barrel 18 are aligned, when the end cover 7 is ready to be loaded into the outer groove 4, it is necessary to ensure that there is no obstruction between the feeding barrel 18 and the outer groove 4. Therefore, it is necessary to drive the rotating rod 13 to rotate through the second output source to make the sleeve 12 away from the outer groove 4. At this time, the sleeve 12 will pass through the through groove 27 to prevent the feeding barrel 18 from blocking the movement trajectory of the sleeve 12. After the rotating rod 13 rotates, it will abut against the extension plate 25, thereby pushing the extension plate 25 away from the feeding barrel. 18, at this time, the extension plate 25 will drive the active rack plate 22 away from the feeding barrel 18 and compress the second spring 26, thereby realizing the unloading process of an end cover 7. After the unloading is completed, it is necessary to rotate the rotating rod 13 in the opposite direction so that the sleeve 12 abuts against the end cover 7 in the outer groove 4 to lock the end cover 7. The abutting effect of the rotating rod 13 is lost, and the second spring 26 will push the active rack plate 22 to approach the feeding barrel 18 again, so that the first insert 20 is reinserted into the feeding barrel 18, thereby preparing for the next unloading.

[0030] like Figure 8 As shown, as a preferred embodiment of the present invention, after the assembly assembly 8 assembles the end cover 7 and the door closer housing 6, the sleeve 12 abuts against the portion of the end cover 7 protruding from the door closer housing 6.

[0031] In actual application of this embodiment, after the end cover 7 and the door closer housing 6 are assembled, the door closer housing 6 will still protrude from the end cover 7, and the sleeve 12 abuts against the part of the end cover 7 protruding from the door closer housing 6, which means that the door closer housing 6 and the end cover 7 cannot be moved out of the inner groove 5 and the outer groove 4. In this way, the assembled door closer housing 6 and the end cover 7 can be driven to continue to move, avoiding the blocking of the outlets of the outer groove 4 and the inner groove 5 by the baffle so that the assembled door closer housing 6 and the end cover 7 cannot be moved out, resulting in the problem that the door closer housing 6 will continue to rub against the baffle, thereby protecting the door closer housing 6.

[0032] like Figure 1-Figure 9As shown, as a preferred embodiment of the present invention, a conveyor belt 17 is arranged below the outer turntable 2 and the inner turntable 3, and two symmetrically arranged electromagnets 16 are fixedly installed on the conveyor belt 17, and a feeding station is formed between the two. The slide bar 11 is connected to the rotating rod 13 through a first spring 14, and the pre-tightening force of the first spring 14 makes the slide bar 11 away from the rotating rod 13, and an iron block 15 is fixedly installed on one end of the slide bar 11 that passes through the rotating rod 13, and the iron block 15 abuts against the rotating rod 13. When the assembled end cover 7 and the door closer housing 6 move to the feeding station, the electromagnet 16 attracts the iron block 15, so that the slide bar 11 compresses the first spring 14, and the sleeve 12 is away from the end cover 7 at this time.

[0033] In actual application of this embodiment, when the outer turntable 2 and the inner turntable 3 rotate to make the assembled door closer housing 6 and end cover 7 move between the two electromagnets 16, the two electromagnets 16 are energized to generate magnetic force, thereby attracting the iron block 15 to move toward the electromagnet 16. At this time, the iron block 15 drives the slide bar 11 to move and compresses the first spring 14. The movement of the slide bar 11 will drive the sleeve 12 to move, thereby making the sleeve 12 move away from the end cover 7, and the sleeve 12 loses the abutment effect on the end cover 7. Under the action of gravity, the assembled end cover 7 and door closer housing 6 will fall onto the conveyor belt 17 and be transported away. Then the two electromagnets 16 are de-energized, and the first spring 14 will reset the slide bar 11, thereby realizing the unloading of the assembled door closer housing 6 and end cover 7 at a specific position.

[0034] See also Figure 1-Figure 9 As shown, the present invention is a heavy-duty ultra-thin door closer assembly method, which is applied to a heavy-duty ultra-thin door closer assembly machine as described in the above embodiment, and the method comprises the following steps: Step S1: The outer turntable 2 and the inner turntable 3 are driven to rotate synchronously through the first output source, so that the outer groove 4 on the outer turntable 2 rotates to the bottom of the loading assembly, and the loading assembly conveys the end cover 7 to the outer groove 4; Step S2: Then the end cap 7 falls onto the multiple round rods 10 in the outer groove 4, and the rotating rod 13 is driven to rotate by the second output source, so that the sleeve 12 abuts against the end cap 7, thereby clamping the end cap 7; Step S3: Then the first output source drives the outer turntable 2 and the inner turntable 3 to rotate synchronously, so that the end cover 7 is rotated to the assembly station; Step S4: placing the door closer housing 6 on the base 1 and pushing it into the inner groove 5 through the telescopic member 9. At this time, the door closer housing 6 is located between the two end covers 7, and the axis of the mounting groove on the door closer housing 6 coincides with the axis of the end cover 7.
