[0002] In the assembly process of automobiles and automotive parts, there are frequent situations where flexible hoses need to be connected to rigid pipes. Currently, this is mostly done manually. For vacuum booster hoses made of relatively hard rubber, lubricants cannot be applied, making installation time-consuming and labor-intensive, which seriously affects the overall assembly efficiency. Summary of the Invention

[0005] The reciprocating drive mechanism includes a forward and reverse motor, which is connected to a reduction gearbox. The reduction gearbox is connected to a first bevel gear, which is connected to a second bevel gear. The second bevel gear is coaxially arranged with a transmission gear. The transmission gear is located on one side of the push rod, and a transmission rack that meshes with the transmission gear is provided on the push rod.

[0006] The reciprocating drive mechanism also includes a clutch for disengaging the forward and reverse motor and the first bevel gear transmission.

[0019] The embodiments of this utility model will be described in detail below with reference to the accompanying drawings. These embodiments are implemented based on the technical solution of this utility model and provide detailed implementation methods and specific working processes. However, the protection scope of this utility model is not limited to the following embodiments.

[0020] like Figure 1-4 As shown, the electric tool for installing vacuum-assisted hoses according to this utility model includes a gun-shaped housing 1, a reciprocating drive mechanism is provided inside the gun-shaped housing 1, a push rod 2 extending outside the gun-shaped housing 1 is provided on the reciprocating drive mechanism, a push head 3 adapted to the hose clamp is provided at the end of the push rod 2, and a fixing member 4 for clamping rigid pipe fittings is also provided on the gun-shaped housing 1.

[0021] Specifically, the reciprocating drive mechanism includes a forward and reverse motor 51, which is connected to a reduction gearbox 52. The reduction gearbox 52 is connected to a first bevel gear 53, which is connected to a second bevel gear 54. The second bevel gear 54 is coaxially arranged with a transmission gear 55, which is located on one side of the push rod 2. A transmission rack 56 meshes with the transmission gear 55 on the push rod 2. When the forward and reverse motor 51 rotates forward, the push rod 2 is propelled forward through the linkage of the reduction gearbox 52, the first bevel gear 53, the second bevel gear 54, the transmission gear 55, and the transmission rack 56. Conversely, when the forward and reverse motor 51 rotates in the reverse direction, the push rod 2 retracts backward. Typically, a self-resetting button 57 for controlling the rotation direction of the forward and reverse motor 51 is installed at the handle of the gun-shaped housing 1. When the self-reset button 57 is pressed, the forward rotation control circuit is activated, the forward and reverse rotation motor 51 rotates forward, and the push rod 2 moves forward; when the self-reset button 57 is released and reset, the reverse rotation control circuit is activated, the forward and reverse rotation motor 51 reverses, and the push rod 2 retracts backward.

[0022] A magnetic induction sensor 61 is installed on the gun-shaped housing 1 to control the forward and reverse motor 51 to stop working. A magnet 62 adapted to the magnetic induction sensor 61 is installed on the push rod 2. The signal output terminal of the magnetic induction sensor 61 is connected to the signal input terminal of the MCU control module 63, and the control output terminal of the MCU control module 63 is connected to the control input terminal of the forward and reverse motor 51. The MCU control module 63 is located inside the gun-shaped housing 1. Both the MCU control module 63 and the forward and reverse motor 51 are connected to the power supply circuit, and the main power switch 7 of the power supply circuit is located on the top of the gun-shaped housing 1. When the main power switch 7 is turned on, power is supplied to all electrical appliances, and the forward and reverse motor 51 is in standby mode. When the self-reset button 57 is pressed, the push rod 2 moves forward; after reaching the position, the self-reset button 57 is released, and the push rod 2 retracts backward; when the push rod 2 retracts to the position, the magnetic induction sensor 61 captures the magnetic field of the magnet 62 and sends a signal to the MCU control module 63. The MCU control module 63 receives the signal and stops the forward and reverse motor 51 from rotating.

[0023] A fixing flange 8 is installed at the head of the gun-shaped housing 1. The fixing flange 8 has a through hole for the push rod 2 to pass through, and the fixing flange 2 is also used to install the fixing component 4. In this embodiment, the push head 3 is a U-shaped clip welded to the end of the push rod 2, and the fixing component 4 is a U-shaped ring with two arms welded to the fixing flange 8. The two arms of the fixing component 4 are both bent structures composed of a first section, a second section, and a third section connected in sequence. The first and third sections are horizontal sections parallel to the push rod 2, while the second section is an inclined section that curves upward away from the push rod 2. In order to better fix the rigid pipe and allow the hose to be installed coaxially with it, the first section of the two arms of the fixing component 4 (i.e., the root of the fixing component 4 near the fixing flange 8) is set on both sides of the push head 3, and the third section at the tail bends upward away from the push head 3 under the action of the second section.

[0024] In use, hold the handle of the gun-shaped housing 1 and engage the push head 3 of the push rod 2 with the clamp N of the hose M, i.e., the push head is located behind the clamp. While pushing the clamp forward, the hose is also pushed forward. Then, the rigid pipe K passes through the fixing member 4 of the U-shaped ring structure and is fixed through the connecting section at the bottom of the fixing member 4. At this time, the hose and the rigid pipe are coaxial. After starting the forward and reverse motor 51, the hose is pushed towards the position of the rigid pipe, and finally the two are fitted together to complete the installation.

[0025] To accommodate the installation of hoses with different diameters, multiple push rods 2 connected to various types of push heads 3 are provided. At this time, a clutch 9 is also provided in the reciprocating drive mechanism to separate the forward / reverse motor 51 and the first bevel gear 53. This clutch 9 uses a planetary gear mechanism located outside the drive shaft of the first bevel gear 53, and the separation of the forward / reverse motor 51 and the first bevel gear 53 is achieved by a separating plate 91 engaging with the notch of the planetary gear 92. At this time, the original push rod 2 can be removed from the transmission mechanism and replaced with a push rod 2 equipped with other types of push heads 3, thereby allowing the installation of hoses with different diameters. The aforementioned separating plate 91 is engaged via a clutch button 93 located on the handle of the gun-shaped housing 1.

[0026] When using the vacuum-assisted hose installation tool described in this utility model, simply clamp the vacuum-assisted hose and rigid pipe fitting onto the corresponding components to align the hose with the port of the rigid pipe fitting to be installed. Press the self-reset button 57 to insert the vacuum-assisted hose into place. This power tool has a compact structure and is very easy and quick to operate, greatly improving the installation time of the vacuum-assisted hose, significantly shortening the overall installation time, increasing production line efficiency, reducing production costs, and demonstrating excellent application prospects.
