Description

Technical Field

[0001] This invention relates to the field of door closer processing technology, and in particular to a door closer end cap assembly machine. Background Technology

[0002] The basic components of a hydraulic door closer include a housing, gear shaft, bushing, piston, spring, seals, end caps, and connecting rod. The housing and connecting rod serve to fix the door closer and connect the door leaf to the door frame.

[0003] The housing has an elongated structure. During assembly, the piston is first placed into the housing, then the gear shaft and bushing are assembled. Next, the spring and seals are installed, and finally the end cap is screwed onto the end of the housing. One end of the end cap has an external thread, and the other end has a groove.

[0004] However, the existing assembly process requires manual labor. When assembling the end cap, the housing needs to be fixed manually, and then a special wrench is used to screw the end cap onto the end of the housing. This results in high labor intensity and low work efficiency. Summary of the Invention

[0005] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a door closer end cap assembly machine, which can reduce labor intensity and improve work efficiency.

[0006] According to an embodiment of the present invention, a door closer end cap assembly machine includes: a machine base; a clamping mechanism for clamping a housing, disposed on the machine base, including a support frame, a fixed plate disposed on one side of the support frame, a movable plate disposed on the other side of the support frame, and a first cylinder for driving the movable plate closer to or further away from the fixed plate, the support frame being used to support the housing; and a screwing mechanism for screwing the end cap to the end of the housing, disposed on the machine base, located on one side of the clamping mechanism, including a rotating component and a translating component, the rotating component being disposed on the translating component, the translating component driving the rotating component closer to or further away from the support frame, the rotating component including a first bracket, a screwing head, and a motor for driving the screwing head to rotate, the motor being mounted on the first bracket, the first bracket being disposed on the translating component, the screwing head having a first protrusion at one end near the support frame, the first protrusion engaging with one end of the end cap, and a pushing component disposed between the motor and the screwing head, the pushing component being used to push the screwing head closer to the end cap.

[0007] A door closer end cap assembly machine according to an embodiment of the present invention has at least the following beneficial effects:

[0008] 1. The present invention provides a support frame, a fixed plate, a movable plate, and a first cylinder. The support frame supports the housing. After the housing is placed on the support frame, the first cylinder drives the movable plate to approach the fixed plate, which can clamp the housing on the support frame, thereby fixing the housing and preventing it from shaking during the capping process.

[0009] 2. This invention, by setting up a translation component and a rotation component, wherein the rotation component includes a first support, a rotating head and a motor, and a pushing component is provided between the motor and the rotating head, and a first protrusion is provided at one end of the rotating head, during operation, the translation component drives the rotation component to move, so that the rotation component is close to the support frame, so that the first protrusion can be engaged and pressed against the end cover. Then, the first motor drives the rotating head to rotate, and at the same time, the pushing component pushes the rotating head towards the side closer to the end cover, thereby realizing the automatic assembly of the door closer end cover, thereby reducing labor intensity and improving work efficiency.

[0010] According to some embodiments of the present invention, the propulsion assembly includes a first main shaft disposed at the output end of the motor, a second main shaft connected to the first main shaft, and a spring disposed between the first main shaft and the second main shaft. The first main shaft drives the second main shaft to rotate, the screwing head is disposed on the second main shaft, and the spring can push the second main shaft to move to the side of the screwing head.

[0011] The advantages are: by setting up a first main shaft, a second main shaft, and a spring, when the translation component drives the rotating component to approach the support frame, the first protrusion of the screwing head first abuts against the end cover. Then, the translation component continues to drive the motor and the first main shaft to move to one side of the support frame, while the second main shaft and the screwing head remain stationary. At this time, the spring is compressed, causing the first main shaft to approach the second main shaft until the spring is compressed to its limit, pressing the end cover tightly against the cylinder end. Then, the motor drives the first main shaft to rotate, the first main shaft drives the second main shaft to rotate, and the second main shaft drives the screwing head to rotate. At the same time, under the action of the spring force, the screwing head drives the end cover to rotate and move towards one side of the cylinder until it is tightened. The structure is simple and easy to implement.

[0012] According to some embodiments of the present invention, a square pin and a first groove cooperating with the square pin are provided between the first spindle and the second spindle, and the square pin is inserted into the first groove along the axial direction of the first spindle.

[0013] The advantage is that by setting a square pin and a first groove, the square pin can be inserted into the first groove along the axial direction of the first main shaft or the second main shaft. On the one hand, the square pin cooperates with the first groove, so that the first main shaft can drive the second main shaft to rotate. On the other hand, the square pin can slide with the first groove along the axial direction of the first main shaft, so that the first main shaft and the second main shaft have a guiding effect when they move relative to each other, ensuring that the first main shaft and the second main shaft are coaxially set.

[0014] According to some embodiments of the present invention, the first spindle is provided with a first flange in the radial direction, the second spindle is provided with a second flange in the radial direction, one end of the spring abuts against the first flange, and the other end of the spring abuts against the second flange.

[0015] The advantage is that by providing a first flange and a second flange, with the first flange abutting against one end of the spring and the second flange abutting against the other end of the spring, the spring can be limited.

[0016] According to some embodiments of the present invention, the first bracket includes a base plate and two side plates respectively disposed on both sides of the base plate, the two side plates being arranged in parallel, the motor being fixed to one side of one of the side plates, the first main shaft being rotatably connected to one of the side plates, and the second main shaft being rotatably connected to the other side plate.

[0017] The advantage is that by setting a base plate and two side plates, with the two side plates arranged in parallel, the two side plates support the first spindle and the second spindle respectively, thereby preventing the first spindle and the second spindle from shaking during rotation and affecting the assembly quality of the end cap.

[0018] According to some embodiments of the present invention, the screwing head includes a capping clamp head and a connecting head, the connecting head being connected to the second spindle, the first protrusion being disposed on the capping clamp head, and a second protrusion and a second groove engaging with the second protrusion being disposed between the connecting head and the capping clamp head.

[0019] The advantage is that by setting up a capping fixture head and a connector head, the capping fixture head and the connector head are set separately. During operation, the operator first aligns the first protrusion on the capping fixture head with and snaps it into the end cap. Then, the second protrusion engages with the second groove, so that the capping fixture head is connected to the connector head. The second spindle drives the connector head to rotate, and the connector head drives the capping fixture head to rotate. This makes it easier to align the first protrusion with the corresponding groove on the end cap, thus improving the stability of the assembly.

[0020] According to some embodiments of the present invention, a support mechanism is also included, the support mechanism including a second bracket, a support block, and a second cylinder for driving the support block to rise and fall, the second cylinder being disposed on the second bracket, the second bracket being disposed on the machine base, and the support block being used to support the capping fixture head.

[0021] The advantages are: by setting a second bracket, a support block, and a second cylinder, the second bracket is used to install the second cylinder, and the support block is located at the telescopic end of the second cylinder. Before screwing the end cap, the second cylinder drives the support block to rise, placing the cap screwing clamp head on the support block, which can support the cap screwing clamp head. Then, the first protrusion is aligned with the corresponding groove on the end cap. When the translation component drives the rotation component to approach the support frame, the cap screwing clamp head presses against the end cap. Then, the second cylinder drives the support block to descend, which can avoid interference between the cap screwing clamp head and the support block when rotating.

[0022] According to some embodiments of the present invention, the translation assembly includes a guide rail, a slider slidably connected to the guide rail, a third cylinder for driving the slider to move, and the first bracket is disposed on the slider.

[0023] The advantages are: by setting up a guide rail, a slider, and a third cylinder, the third cylinder drives the slider to move, and the slider drives the rotating component to move along the guide rail. The guide rail has a guiding function, thereby enabling the screwing head to be aligned with the end cap, improving the stability and accuracy of the equipment.

[0024] According to some embodiments of the present invention, a control mechanism is further included, the control mechanism including a control box, a first inductive switch and a second inductive switch, the first inductive switch being used to sense the position of the slider, the second inductive switch being used to sense the position of the screw head, the first inductive switch and the second inductive switch being electrically connected to the control box, the control box being used to control the operation of all power devices.

[0025] The advantages are: by setting up a control mechanism, the first inductive switch is located on one side of the guide rail, and the second inductive switch is located on the side of the screwing head. When the third cylinder drives the slider to move and compresses the spring to its limit, the first inductive switch senses the position of the slider and transmits a signal to the control box. The control box controls the motor to rotate, causing the screwing head to screw the end cover. After tightening, the second inductive switch senses the position of the screwing head and transmits a signal to the control box. The control box controls the motor to stop rotating, and then the control box controls the third cylinder to drive the slider back. Thus, the orderly operation of each power device can be realized, improving the automation level of the equipment.

[0026] According to some embodiments of the present invention, a rocker arm is provided between the first cylinder and the movable plate, the rocker arm is rotatably connected to the support frame, one end of the rocker arm is hinged to the telescopic end of the first cylinder, and the other end of the rocker arm is fixedly connected to the movable plate.

[0027] The advantage is that by setting up a rocker arm, the first cylinder drives the rocker arm to swing, and the rocker arm drives the movable plate to swing, so that the movable plate moves closer to or away from the fixed plate. The first cylinder can be set at the bottom of the support frame, thus making the equipment structure compact and saving space.

[0039] A door closer end cap assembly machine according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0040] Reference Figure 1 and Figure 2 An embodiment of the present invention provides a door closer end cap assembly machine, comprising a machine base 100, a clamping mechanism 110, and a screwing mechanism 160.

[0041] In terms of arrangement, both the clamping mechanism 110 and the screwing mechanism 160 are mounted on the machine base 100, with the screwing mechanism 160 located on one side of the clamping mechanism 110.

[0042] Functionally, the clamping mechanism 110 is used to clamp the housing of the door closer.

[0043] Structurally, the clamping mechanism 110 includes a support frame 120, a fixed plate 130 disposed on one side of the support frame 120, a movable plate 140 disposed on the other side of the support frame 120, and a first cylinder 150 for driving the movable plate 140 to move closer to or away from the fixed plate 130. The support frame 120 is used to support the housing.

[0044] Furthermore, the screwing mechanism 160 is used to screw the end cap to the end of the housing, and includes a rotating component 170 and a translating component 180. The rotating component 170 is disposed on the translating component 180, and the translating component 180 drives the rotating component 170 to move closer to or away from the support frame 120. The rotating component 170 includes a first bracket 190, a screwing head 200, and a motor 210 that drives the screwing head 200 to rotate. The motor 210 is mounted on the first bracket 190, and the first bracket 190 is disposed on the translating component 180. The screwing head 200 has a first protrusion 220 at one end near the support frame 120, and the first protrusion 220 engages with one end of the end cap. A pushing component 230 is disposed between the motor 210 and the screwing head 200, and the pushing component 230 is used to push the screwing head 200 toward the side closer to the end cap.

[0045] During operation, the housing is first placed on the support frame 120. Then, the first cylinder 150 drives the movable plate 140 to approach the fixed plate 130, which clamps the housing on the support frame 120, thereby fixing the housing and preventing it from shaking during the capping process. Then, the translation component 180 drives the rotation component 170 to move, so that the rotation component 170 approaches the support frame 120, which allows the first protrusion 220 to engage and press against the end cap. Next, the first motor 210 drives the screwing head 200 to rotate, and at the same time, the push component 230 pushes the screwing head 200 towards the side closer to the end cap. Thus, the automatic assembly of the door closer end cap can be realized, thereby reducing labor intensity and improving work efficiency.

[0046] Reference Figure 2 , Figure 3 and Figure 4 In some preferred embodiments, the propulsion assembly 230 includes a first main shaft 240 disposed at the output end of the motor 210, a second main shaft 250 connected to the first main shaft 240, and a spring 260 disposed between the first main shaft 240 and the second main shaft 250. The first main shaft 240 drives the second main shaft 250 to rotate, and a screwing head 200 is disposed on the second main shaft 250. The spring 260 can push the second main shaft 250 to move toward the screwing head 200.

[0047] Understandably, by setting up a first spindle 240, a second spindle 250, and a spring 260, when the translation component 180 drives the rotation component 170 to approach the support frame 120, the first protrusion 220 of the screwing head 200 first abuts against the end cover. Then, the translation component 180 continues to drive the motor 210 and the first spindle 240 to move towards the support frame 120, while the second spindle 250 and the screwing head 200 remain stationary. At this time, the spring 260 is compressed, causing the first spindle 240 to approach the second spindle 250, until the spring 260 is compressed to its limit, pressing the end cover tightly against the cylinder end. Then, the motor 210 drives the first spindle 240 to rotate, the first spindle 240 drives the second spindle 250 to rotate, and the second spindle 250 drives the screwing head 200 to rotate. At the same time, under the action of the spring force of the spring 260, the screwing head 200 drives the end cover to rotate and move towards the cylinder side simultaneously until it is tightened. The structure is simple and easy to implement.

[0048] In some preferred embodiments, a square pin 270 and a first groove 280 that engages with the square pin 270 are provided between the first spindle 240 and the second spindle 250, and the square pin 270 is inserted into the first groove 280 along the axial direction of the first spindle 240.

[0049] It is understandable that by setting a square pin 270 and a first groove 280, the square pin 270 can be inserted into the first groove 280 along the axial direction of the first main shaft 240 or the second main shaft 250. On the one hand, the square pin 270 cooperates with the first groove 280, so that the first main shaft 240 can drive the second main shaft 250 to rotate. On the other hand, the square pin 270 can slide along the axial direction of the first main shaft 240 and the first groove 280, so that the first main shaft 240 and the second main shaft 250 have a guiding effect when they move relative to each other, ensuring that the first main shaft 240 and the second main shaft 250 are coaxially set.

[0050] In some preferred embodiments, the first spindle 240 is provided with a first flange 290 in the radial direction, the second spindle 250 is provided with a second flange 300 in the radial direction, one end of the spring 260 abuts against the first flange 290, and the other end of the spring 260 abuts against the second flange 300.

[0051] It is understandable that by setting a first flange 290 and a second flange 300, with the first flange 290 abutting against one end of the spring 260 and the second flange 300 abutting against the other end of the spring 260, the spring 260 can be limited.

[0052] In some preferred embodiments, the first support 190 includes a base plate 310 and two side plates 320 respectively disposed on both sides of the base plate 310. The two side plates 320 are arranged in parallel. The motor 210 is fixed to one side of one of the side plates 320. The first spindle 240 is rotatably connected to one of the side plates 320, and the second spindle 250 is rotatably connected to the other side plate 320.

[0053] It is understandable that by setting a base plate 310 and two side plates 320, with the two side plates 320 arranged in parallel, the two side plates 320 respectively support the first spindle 240 and the second spindle 250, thereby preventing the first spindle 240 and the second spindle 250 from shaking during rotation and affecting the assembly quality of the end cap.

[0054] In some preferred embodiments, the screwing head 200 includes a capping clamp head 330 and a connector head 340. The connector head 340 is connected to the second spindle 250. A first protrusion 220 is disposed on the capping clamp head 330. A second protrusion 350 and a second groove 360 ​​engaging with the second protrusion 350 are disposed between the connector head 340 and the capping clamp head 330.

[0055] Understandably, by setting the capping clamp head 330 and the connector head 340 separately, during operation, the operator first aligns the first protrusion 220 on the capping clamp head 330 with and inserts it into the end cap. Then, the second protrusion 350 engages with the second groove 360, connecting the capping clamp head 330 to the connector head 340. This causes the second spindle 250 to drive the connector head 340 to rotate, and the connector head 340 to drive the capping clamp head 330 to rotate. This facilitates aligning the first protrusion 220 with the corresponding groove on the end cap, improving assembly stability.

[0056] In some preferred embodiments, a support mechanism 370 is also included. The support mechanism 370 includes a second bracket 380, a support block 390, and a second cylinder 400 for driving the support block 390 to rise and fall. The second cylinder 400 is disposed on the second bracket 380, which is disposed on the machine base 100. The support block 390 is used to support the capping fixture head 330.

[0057] Understandably, by setting up a second bracket 380, a support block 390, and a second cylinder 400, the second bracket 380 is used to install the second cylinder 400, and the support block 390 is located at the telescopic end of the second cylinder 400. Before screwing the end cap, the second cylinder 400 drives the support block 390 to rise, placing the cap screwing clamp head 330 on the support block 390 to support the cap screwing clamp head 330. Then, the first protrusion 220 is aligned with the corresponding groove on the end cap. When the translation component 180 drives the rotation component 170 to approach the support frame 120, the cap screwing clamp head 330 presses the end cap. Then, the second cylinder 400 drives the support block 390 to descend, which can prevent the cap screwing clamp head 330 from interfering with the support block 390 when rotating.

[0058] In some preferred embodiments, the translation component 180 includes a guide rail 410, a slider 420 slidably connected to the guide rail 410, a third cylinder 430 for driving the slider 420 to move, and a first bracket 190 disposed on the slider 420.

[0059] It is understandable that by setting up the guide rail 410, the slider 420 and the third cylinder 430, the third cylinder 430 drives the slider 420 to move, and the slider 420 drives the rotating component 170 to move along the guide rail 410. The guide rail 410 has a guiding function, thereby enabling the screwing head 200 to be aligned with the end cover, improving the stability and accuracy of the equipment.

[0060] In some preferred embodiments, a control mechanism 450 is also included. The control mechanism 450 includes a control box 460, a first inductive switch 470 and a second inductive switch 480. The first inductive switch 470 is used to sense the position of the slider 420, and the second inductive switch 480 is used to sense the position of the rotating head 200. The first inductive switch 470 and the second inductive switch 480 are electrically connected to the control box 460, which is used to control the operation of the power device.

[0061] Understandably, by setting up the control mechanism 450, the first inductive switch 470 is located on one side of the guide rail 410, and the second inductive switch 480 is located on one side of the screw head 200. When the third cylinder 430 drives the slider 420 to move and compresses the spring 260 to its limit, the first inductive switch 470 senses the position of the slider 420 and transmits a signal to the control box 460. The control box 460 controls the motor 210 to rotate, causing the screw head 200 to screw the end cover. After tightening, the second inductive switch 480 senses the position of the screw head 200 and transmits a signal to the control box 460. The control box 460 controls the motor 210 to stop rotating. Then, the control box 460 controls the third cylinder 430 to drive the slider 420 back. Thus, the orderly operation of each power device can be realized, improving the automation level of the equipment.

[0062] In some preferred embodiments, a rocker arm 440 is provided between the first cylinder 150 and the movable plate 140. The rocker arm 440 is rotatably connected to the support frame 120. One end of the rocker arm 440 is hinged to the telescopic end of the first cylinder 150, and the other end of the rocker arm 440 is fixedly connected to the movable plate 140.

[0063] It is understandable that by setting up the rocker arm 440, the first cylinder 150 drives the rocker arm 440 to swing, and the rocker arm 440 drives the movable plate 140 to swing, so that the movable plate 140 moves closer to or away from the fixed plate 130. The first cylinder 150 can be set at the bottom of the support frame 120, thereby making the equipment structure compact and saving space.

Before screwing the end cap, the second cylinder drives the support block to rise, placing the capping clamp head on the support block for support. The operator first aligns the first protrusion on the capping clamp head with and engages it with the end cap. Then, the second protrusion engages with the second groove, connecting the capping clamp head to the connector. The translation component drives the rotation component to approach the support frame, pressing the capping clamp head against the end cap. Then, the second cylinder drives the support block to descend, preventing interference between the capping clamp head and the support block during rotation. This causes the second spindle to rotate the connector, which in turn drives the capping clamp head to rotate.
