Description

Technical Field

[0001] The present invention relates to the technical field of press-fitting devices, and particularly to an F-rod handle press-fitting device and method. Background Art

[0002] A press-fitting device is mainly a device used to assemble one component onto another by applying pressure. Its basic principle is to utilize pressure to generate a sufficient interference fit between two mating parts, thereby achieving a firm connection. For example, in mechanical manufacturing, when press-fitting a bushing onto a shaft, an axial pressure is applied to the bushing through the press-fitting device, causing the inner diameter of the bushing to undergo elastic deformation. When the bushing is pressed onto the outer diameter of the shaft and the pressure is removed, the bushing tightly holds the shaft due to elastic recovery, forming a tight fit.

[0003] The tooling fixture of the F-rod handle press-fitting device is designed for F-rod handles of specific sizes. When press-fitting F-rod handles of different sizes, a large number of fixture parts may need to be replaced, which not only increases production costs but also reduces production flexibility. For example, for F-rod handles that are slightly larger or smaller in size, the existing fixtures may not be able to effectively fix them, and special fixtures need to be customized, resulting in interruptions in the production process. Summary of the Invention

[0004] The purpose of the present invention is to provide an F-rod handle press-fitting device and method to solve the above problems.

[0005] To achieve the above purpose, the present invention adopts the following technical solutions: It includes a conveyor belt. At one end above the conveyor belt, a first storage box for storing handles is installed. At the middle position above the conveyor belt, a clamping device is installed. On one side of the conveyor belt, a workbench is fixedly installed. At the upper end of the workbench, a second storage box for cooperating with the clamping device is installed. Inside the clamping device, a clamping member is installed. At the middle position of the conveyor belt, a lifting device for cooperating with the clamping device is installed. At the middle position of the conveyor belt, a gap for cooperating with the lifting device is provided. On one side of the second storage box, a pressing device is installed. On the outer wall of the first storage box, a baffle for cooperating with the clamping device is fixedly provided;

[0006] The clamping member includes a first belt. Inside the upper end of the C-shaped shell of the clamping device, a driving group, a tensioning group, and two transmission groups for cooperating with the first belt are installed. The two transmission groups are respectively installed on both sides inside the C-shaped shell. At both ends of the transmission group, first spring telescopic rods are respectively rotationally installed. At the middle position of the transmission group, a rotating shaft for cooperating with it is installed. At both ends of the rotating shaft, transmission boxes are installed. Between the two groups of transmission boxes, two rotating cylinders are installed. On the outer walls of the two rotating cylinders, a second belt is installed;

[0007] The clamping device includes a first hydraulic telescopic rod. The lower end of the first hydraulic telescopic rod is fixedly installed with a mounting plate. The lower end of the mounting plate is slidably installed with a U-shaped shell. The length from the lowermost end of the U-shaped shell to the lowermost end of the mounting plate is longer than the length from the upper surface of the baffle to the extreme position where the conveyor belt is compressed.

[0008] In practical applications, the conveyor belt transports the first storage box. The first hydraulic telescopic rod extends downward. The hydraulic telescopic rod drives the U-shaped shell to move downward through the mounting plate. The U-shaped shell drives the clamping member to move downward, thereby clamping the handle into the interior of the U-shaped shell. Subsequently, the driving group drives the first belt. The first belt drives the transmission group to rotate. The transmission group drives the rotating shaft to rotate. The rotating shaft drives the rotating cylinder to rotate through the transmission box. The rotating cylinder drives the handle to rotate, aligning the groove of the handle with the square head. Subsequently, the electric telescopic rod in the second storage box pushes the square head to be connected to the handle. At this time, the hinge holes of the square head and the handle are aligned with the feeding hole. Subsequently, the feeding device pushes the hinge shaft to the upper end of the feeding hole. Then, the electric telescopic rod pushes the square head, causing the square head to脱离 the bottom slideway of the second storage box. Subsequently, the pressing device presses down the hinge shaft, deforming the top of the hinge shaft, thereby completing the press-fitting of the F-rod handle. Subsequently, the first hydraulic telescopic rod in the clamping device contracts upward. The baffle blocks the F-rod handle, causing the F-rod handle to disengage from the clamping member. Subsequently, the conveyor belt transports the F-rod handle to the collection box, facilitating the press-fitting and forming of the F-rod handle.

[0009] Further, the driving group includes a motor installed inside the U-shaped shell. The lower end of the output shaft of the motor is fixedly installed with a third pulley for use with the first belt. The tensioning group includes a chute fixedly installed at the top of the U-shaped shell. A slider is slidably arranged inside the chute. The upper end of the slider is rotatably installed with a fourth pulley.

[0010] The transmission box includes a T-shaped mounting shell. The outer wall of the T-shaped mounting shell is symmetrically installed with second spring telescopic rods. The two ends inside the T-shaped mounting shell are respectively rotatably installed with rotating rods. The rotating cylinder is installed on the outer wall of the rotating rod. The first spring telescopic rod has the same structure as the second spring telescopic rod.

[0011] The transmission group includes a rotating shaft. A worm is fixedly installed at the middle position of the rotating shaft. A second pulley for use with the first belt is fixedly installed at one end of the rotating shaft.

[0012] In practical applications, when the handle enters the position between the second belts, the handle will open the clamping member, and the second spring telescopic rod is compressed. Subsequently, the T-shaped mounting shell drives the rotating shaft to move. The rotating shaft drives the transmission group to move. The transmission group will change the first belt. The tensioning group always keeps the first belt under a certain tension, thereby preventing the first belt from falling off and adapting to handles of different specifications and sizes.

[0013] Furthermore, a slide is provided at the lower end of the second storage box, a magnet for use with a square head is pasted on the lower end of the slide, an electric telescopic rod is installed at one end of the slide, a feed hole for use with a square head is installed on the outer wall of the workbench, a feeding device is installed at the lower end of the feed hole, and the feed hole is a trumpet hole.

[0014] Furthermore, the lifting device includes a third spring telescopic rod, and two rollers used in conjunction with the clamping device are rotatably mounted on the upper end of the third spring telescopic rod.

[0015] Furthermore, a method for press-fitting an F-bar handle comprises the following steps:

[0016] Preparation: Prepare the F-handle and the parts to be pressed, and make sure their surfaces are clean, free of oil and impurities;

[0017] Apply lubricant: Apply a proper amount of lubricant to the press-fit part of the F-handle to reduce friction and wear;

[0018] Install the handle: Insert the F-handle into the part that needs to be press-fitted, making sure the handle and the part fit well;

[0019] Apply pressure: Use this device to fit the handle and square head together;

[0020] Check the press-fit effect: After the press-fit is completed, check whether the connection between the handle and the square head is firm; Test: If necessary, the handle can be tested to ensure that it can work properly during use.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] When the handle enters the position between the second belts, the handle will open the clamping piece, the second spring telescopic rod will be compressed, and then the T-shaped mounting shell will drive the rotating shaft to move, and the rotating shaft will drive the transmission group to move. The transmission group will change the first belt, and the tensioning group will always keep a certain tension on the first belt to prevent the first belt from falling off, thereby adapting to handles of different sizes.

[0037] The clamping member 8 includes a first belt 801.
