Description

Technical Field

[0001] The invention relates to the technical field of faucets, and in particular to a hose screw-in tool. Background Art

[0002] During the processing and manufacturing process of the faucet, the faucet body and the wire braided hose need to be assembled together, which requires workers to manually screw the hose into the faucet body. This manual assembly method is not only repetitive and boring, and has low assembly efficiency, but may also damage the workers' wrists and affect their physical and mental health if carried out for a long time. Summary of the invention

[0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. To this end, the present invention provides a hose screw-in tool, which can improve the assembly efficiency of the faucet.

[0004] A hose screw-in tooling according to an embodiment of the present invention comprises a base, a motor and a mounting assembly; the motor is mounted on the base, and an elastic sleeve is connected to the output end of the motor; the mounting assembly is provided with a guide rod, a cylinder and a push plate, the guide rod is mounted on the base and is located on the same side of the base as the elastic sleeve, the push plate is slidably connected to the guide rod, the push plate is provided with a mounting groove, the groove wall of the mounting groove is arranged around the elastic sleeve, two pressing pieces are provided on the side of the push plate away from the elastic sleeve, and the two pressing pieces are symmetrically arranged on both sides of the mounting groove, the cylinder is mounted on the base, and the output end of the cylinder is connected to the push plate to drive the pressing piece to move in a direction approaching or away from the elastic sleeve.

[0005] A hose screw-in tool according to an embodiment of the present invention has at least the following beneficial effects: when a worker assembles a wire braided hose and a faucet body, he first screws the hose into the faucet body half a circle, then fixes the faucet body, and then places the connector of the hose away from the faucet body in the installation groove, and then starts the cylinder. The cylinder usually selects a telescopic cylinder with low cost and a variety of types. The telescopic cylinder controls the push plate to move toward the elastic sleeve, and the pressing pieces on both sides of the installation groove press the circumference of the connector, thereby pushing the connector of the hose to move in the direction close to the elastic sleeve. Driven by the cylinder, the elastic sleeve will extend into the notch of the connector and clamp with the connector, and then the motor is started. , the motor drives the elastic sleeve to rotate, thereby driving the hose to rotate, so that the hose is automatically screwed into the faucet body. As the depth of the hose screwing in increases, the friction between the faucet body and the hose will gradually increase until the hose is completely screwed into the faucet body. The torque generated by the friction will be greater than the torque of the elastic sleeve, and the elastic sleeve begins to slip in the groove. At this time, the cylinder drives the push plate to move away from the elastic sleeve, thereby loosening the hose to facilitate workers to take the parts and complete the assembly of the faucet. This arrangement allows the assembly of the faucet body and the wire braided hose to be automatic, saving the time and labor costs spent on workers manually screwing in, effectively improving the assembly efficiency of the faucet, and protecting the physical and mental health of workers.

[0023] The embodiments of the present application will be further described below in conjunction with the accompanying drawings.

[0024] Refer to Figures 1 to 4 , a hose screwing tooling according to an embodiment of the present invention includes a base 100, a motor 200, and a mounting assembly 300; the base 100 is provided with a first through hole (not shown in the figure) and a second through hole (not shown in the figure), the first through hole is located above the second through hole, the motor 200 is provided with a connecting flange 240, the connecting flange 240 is connected to the base 100, and the rotating shaft of the motor 200 passes through the first through hole and is connected with an elastic sleeve 210; the mounting assembly 300 is provided with a guide rod 310, a cylinder 320, and a push plate 330, the guide rod 310 is installed on the base 100 and is on the same side of the base 100 as the elastic sleeve 210, the push plate 330 is slidably connected to the guide rod 310, the push plate 330 is provided with a mounting groove 301 corresponding to the elastic sleeve 210, the push plate 330 is provided with two pressing members 331, the two pressing members 331 are symmetrically arranged on both sides of the mounting groove 301, the cylinder 320 is installed on the base 100, and the cylinder 320 and the motor 200 are on the same side of the base 100, and the output end of the cylinder 320 is connected to the push plate 330 to drive the pressing members 331 to move towards or away from the elastic sleeve 210.

[0025] It can be understood that when the worker assembles the wire braided hose and the faucet body, first screw the hose into the faucet body half a turn, and then fix the faucet body. The faucet body can be placed on a bracket (not shown in the figure) or held by the worker. Regardless of the fixing method, the hose between the faucet body and the screwing tool is always in a flat and straightened state, that is, the axis of the hose is collinear with the axis of the motor output shaft. Then place the connector at the end of the hose away from the faucet body (a cylindrical workpiece with internal threads, used to connect devices such as water tanks and water pipes to supply water to the faucet body) in the installation groove 301. Subsequently, start the cylinder 320. The cylinder 320 usually selects a telescopic cylinder 320 with low cost and various types. The telescopic cylinder 320 controls the push plate 330 to move towards the elastic sleeve 210. The pressing members 331 on both sides of the installation groove 301 will press the circumferential surface of the connector, thereby pushing the connector of the hose towards the elastic sleeve 210. Driven by the cylinder 320, the elastic sleeve 210 will extend into the slot of the connector and be clamped with the connector. Specifically, the elastic sleeve 210 presses the bottom surface of the slot of the connector, and the pressing members 331 on both sides press the circumferential surface of the connector. The elastic sleeve 210 and the pressing members 331 cooperate to clamp the connector of the hose in the horizontal direction. Since the elastic sleeve 210 is located between the two pressing members 331, that is, there is a certain distance between the points pressed on both sides of the connector, the elastic sleeve 210 and the pressing members 331 will not jam the connector, providing a prerequisite for the subsequent rotation of the connector. Immediately start the motor 200. The motor 200 drives the elastic sleeve 210 to rotate, thereby driving the hose to rotate, so that the hose is automatically screwed into the faucet body. As the depth of the hose screwed into the faucet body increases, the friction force between the faucet body and the hose will gradually increase. Until the hose is completely screwed into the faucet body, the torque generated by the friction force will be greater than the torque of the elastic sleeve 210, and the elastic sleeve 210 will start to slip in the slot. At this time, the cylinder 320 drives the push plate 330 to move away from the elastic sleeve 210, thereby loosening the hose to facilitate the worker to pick up the part, completing the assembly of the faucet. With this setting, the assembly of the faucet body and the wire braided hose is automatically carried out, saving the time cost and labor cost spent by the worker in manual screwing, effectively improving the assembly efficiency of the faucet, and ensuring the physical and mental health of the worker.

[0026] Furthermore, there are multiple installation components 300, which are arranged at intervals in the horizontal direction. There are also multiple motors 200 and elastic sleeves 210, and the motors 200, elastic sleeves 210 and installation components 300 correspond to each other one by one. When assembling the faucet, the worker can first screw multiple wire-braided hoses into the corresponding faucet body by half a turn, and then install the ends of the multiple hoses facing away from the faucet body into different installation slots 301. Subsequently, the motors 200 and cylinders 320 corresponding to each installation component 300 start to work normally. By setting multiple installation components 300, the worker can assemble multiple faucets simultaneously, greatly saving the time cost required for manual assembly and further improving the assembly efficiency of the faucet.

[0027] Referring to Figure 1 and Figure 2 , it can be understood that the elastic sleeve 210 is provided with a jack 201 and a threaded hole 202. The axis of the jack 201 is collinear with the center line of the elastic sleeve 210, the axis of the threaded hole 202 is perpendicular to the center line of the elastic sleeve 210, the jack 201 and the threaded hole 202 are communicated. The output shaft of the motor 200 is inserted into the jack 201, and the elastic sleeve 210 is connected with a first screw 220. The first screw 220 is installed in the threaded hole 202 and abuts against the rotating shaft of the motor 200. By setting the first screw 220 to fix the elastic sleeve 210, the installation stability of the elastic sleeve 210 can be effectively improved. On the one hand, when the user removes the hose, it can avoid the elastic sleeve 210 being too tightly clamped with the hose and causing the elastic sleeve 210 to separate from the motor 200, improving the user experience. On the other hand, it can improve the rotation stability of the elastic sleeve 210, thus ensuring that the hose can be stably screwed into the faucet body and reducing the rejection rate of faucet assembly.

[0028] Furthermore, a plain bearing 230 (also known as a thrust bearing, which is an element composed of a flat cage assembly with needle rollers or cylindrical rollers or steel balls and a flat washer) is provided between the elastic sleeve 210 and the motor 200. The plain bearing 230 is sleeved on the rotating shaft of the motor 200. One flat washer on one side of the plain bearing 230 is clamped with the connection flange 240 of the motor 200, and the other flat washer on the other side abuts against the elastic sleeve 210. The plain bearing 230 can obtain high load capacity and high stiffness in a very small space. On the premise that the connection head of the hose is clamped in the horizontal direction, the elastic sleeve 210 can drive the connection head to rotate. By setting the plain bearing 230, the traditional washer parts can be omitted, making the connection structure between the motor 200 and the elastic sleeve 210 more stable and compact. In addition, the plain bearing 230 can be selected as a plain needle bearing or a plain cylindrical roller bearing. At this time, the cylindrical surface of the needle or cylindrical roller of the plain bearing 230 is used as the modified surface, which can reduce the edge stress of the elastic sleeve 210 and effectively improve the service life of the elastic sleeve 210.

[0029] Furthermore, a guide portion 211 is provided at one end of the elastic sleeve 210 facing the pressing member 331, for guiding the elastic sleeve 210 to be inserted into the orifice of the hose. The outer diameter of the installation groove 301 is usually larger than the cross-sectional area of ​​the connector, so that after the connector and the elastic sleeve 210 are engaged, there is a certain gap between the connector and the groove wall of the installation groove 301, thereby ensuring that the hose will not be blocked by the groove wall of the installation groove 301 when rotating. However, with such an arrangement, when the worker places the connector into the installation groove 301, the connector and the elastic sleeve 210 are not coaxial. By providing the guide portion 211, when the push plate 330 drives the connector to move toward the elastic sleeve 210, the guide portion 211 can guide the elastic sleeve 210 to enter the groove hole of the connector, thereby reducing the friction between the elastic sleeve 210 and the connector, and effectively improving the installation efficiency of the hose.

[0030] Reference Figure 1 and Figure 3 It can be understood that the end of the guide rod 310 away from the base 100 is connected to the mounting plate 340, and the side of the mounting plate 340 away from the base 100 is connected to the mounting frame 341, and the mounting frame 341 is provided with a slot, and the pressure sensor 400 is connected to the slot, and the pressure sensor 400 is located between the two pressing members 331 and below the elastic sleeve 210. The pressure sensor 400 is electrically connected to the cylinder 320, and the detection end of the pressure sensor 400 is set upward. During the assembly process of the faucet, when the worker places the connector into the mounting slot 301, the hose will also be placed on the pressure sensor 400. The pressure sensor 400 senses the hose and controls the cylinder 320 to start, so that the screw-in device automatically installs the hose and performs subsequent operations. By setting the sensor, the automation of the screw-in device can be improved, and the entire process of hose assembly can be automated, further improving the assembly efficiency of the hose and improving the user experience.

[0031] It should be noted that, under the premise of setting up multiple installation components 300, the installation plates 340 of the multiple installation components 300 can be a whole long plate. Such a setting can improve the stability of the overall structure of the screw-in device. The installation plates 340 of the multiple installation components 300 can also be independent plates. Such a setting can make the screw-in device more modular, facilitate users to disassemble and maintain a single installation component 300, and improve the user experience.

[0032] Furthermore, the mounting plate 340 is provided with an avoidance portion 302, and the avoidance portion 302 is used to avoid the pressing member 331. Since the push plate 330 moves along the guide direction of the guide rod 310, and the mounting plate 340 is fixed to the end of the guide rod 310, by providing the avoidance portion 302, it is possible to avoid the mounting plate 340 from hindering the movement of the pressing member 331 during the movement of the push plate 330, thereby improving the movement stability of the push plate 330.

[0033] ReferenceFigure 3 and Figure 4 Figure 4 , it can be understood that the pressing member 331 is bolted to the push plate 330 by the second screw 332. The pressing member 331 is provided as a ball bearing. The inner ring of the ball bearing is in interference fit with the second screw 332, and the rotating shaft of the ball bearing is parallel to the guide rod 310. With such a setting, during the rotation of the connector, the ball bearings on both sides will also rotate synchronously, thereby reducing the frictional force exerted by the pressing member 331 on the connector, enabling more of the output torque of the motor 200 to be converted into the rotational speed of the connector, and further improving the assembly efficiency of the faucet.

[0034]

[0034] Furthermore, a washer 350 is provided between the ball bearing and the push plate 330. The washer 350 is sleeved on the second screw 332, and both sides of the washer 350 are in contact with the ball bearing and the push plate 330 respectively. By providing the washer 350, on the one hand, the distance between the ball bearing and the push plate 330 can be increased, avoiding the push plate 330 from hindering the rotation of the ball bearing during the rotation of the ball bearing and thus hindering the rotation of the connector, indirectly improving the rotational stability of the hose. On the other hand, by providing the washer 350, the washer 350 can buffer the ball bearing, reduce the vibration phenomenon generated during the rotation of the ball bearing, improve the rotational stability of the ball bearing, and extend the service life of the ball bearing.

[0035]

[0035] Furthermore, a guide sleeve 360 is provided between the push plate 330 and the guide rod 310. The guide sleeve 360 is installed on the push plate 330. The guide sleeve 360 is provided with a guide hole, and the guide rod 310 passes through the guide hole. By providing the guide sleeve 360, the friction between the guide rod 310 and the push plate 330 can be reduced, improving the moving stability of the push plate 330 while effectively extending the service lives of the push plate 330 and the guide rod 310.
