Description

Technical Field

[0001] This utility model belongs to the technical field of hose needle punching equipment, and relates to a hose needle punching device. Background Technology

[0002] Rubber hoses are a common connecting tool used to connect various devices and are an indispensable connecting material in factories. However, during the use of rubber hoses, it is sometimes necessary to needle them. But because manual needle-punching of rubber hoses is inefficient and the needle depth is inconsistent, it affects the normal use of the rubber hose. Chinese patent CN212455953U discloses a continuous needle-punching device for the outer rubber layer of hydraulic hoses to prevent bulging of the outer rubber layer. The device includes a frame, a first needle-punching mechanism, a hydraulic hose body, a first guide wheel, a second guide wheel, a third guide wheel, and a second needle-punching mechanism. The support legs of the frame are equipped with universal wheels with brakes at the bottom. This invention, by setting a gear ring, a first gear, a support plate, and a second gear, ensures that when the hydraulic hose body undergoes a slight change in direction during the needle-punching and pulling process, the needle-punching device also rotates accordingly, thus preventing damage to the hydraulic hose body from the needle-punching device. By setting a first guide wheel, a second guide wheel, and a third guide wheel, the hydraulic hose body enters and exits from the same side during needle-punching, reducing the space required for needle-punching. Furthermore, during needle-punching, the guide wheels compress the hydraulic hose body, allowing the gas accumulated inside the hydraulic hose body to dissipate more thoroughly, greatly improving needle-punching efficiency. However, this technical solution suffers from low puncture efficiency and inconvenience in puncturing hoses of different diameters. Utility Model Content

[0003] To address the aforementioned problems, this utility model proposes a tubing needle piercing device, which effectively solves the problems of low piercing efficiency and inconvenience in piercing tubing of different diameters in the prior art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A tubing needle-punching device includes a base plate, a support plate fixedly connected to the upper side of the base plate, a tray fixedly connected to the upper side of the support plate, a first insertion hole on the circumferential side of the tray, a placement plate detachably connected to the front side of the tray, a second insertion hole at the center of the circumferential side of the placement plate, the first insertion hole and the second insertion hole being through each other, a tubing passing through the first insertion hole and the second insertion hole, adjusting plates inserted into the left and right sides of the first insertion hole, auxiliary clamping wheels hinged to the inner side of each adjusting plate, multiple positioning grooves arranged in a circumferential array on the front circumferential side of the placement plate, top plates being provided along the radial direction of the positioning grooves, the top plates being slidable along the positioning grooves, adjusting components located inside the placement plate being engaged with the inner side of the top plates for simultaneously adjusting multiple top plates radially along the placement plate, fixing plates fixedly connected to the front side of each top plate, piercing wheels hinged to the front side of each fixing plate, and multiple evenly distributed needles of the same size fixedly connected to the inner side of each piercing wheel.

[0006] Preferably, the adjusting component includes a fixed shaft coaxially fixed to the placement tray, a large bevel gear rotatably connected to the front end of the fixed shaft, both the fixed shaft and the large gear having through holes that communicate with the first insertion hole and the second insertion hole, a plurality of evenly distributed small bevel gears meshing with the large bevel gear, a fixed rod fixedly connected to the middle of each small bevel gear, one end of the fixed rod extending to the outer side of the placement tray and rotatably connected to the placement tray, an adjusting plate fixedly connected to the front end of the large bevel gear, the adjusting plate having a spiral groove, a plurality of spiral plates fixedly connected to the rear side of the top plate, the spiral plates meshing with the spiral groove.

[0007] Preferably, each of the fixing rods has a square groove.

[0008] Preferably, the bottom side of the base plate has multiple evenly distributed assembly holes.

[0009] Preferably, the puncture wheel is made of hard plastic.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] 1. Based on the position of the hose passing between the auxiliary clamping wheels and entering the first insertion hole of the tray, continue to move the hose towards the second insertion hole. When it enters the second insertion hole of the tray, by adjusting the adjusting component, multiple top plates are moved simultaneously towards the hose, so that the outer side of the hose contacts the positions of multiple piercing wheels. Continue to move the hose forward to facilitate the efficient piercing of the hose by the piercing needles on the piercing wheels.

[0012] 2. By rotating the fixed rod, the adjustment disc is driven to rotate due to the cooperation of the small bevel gear and the large bevel gear. Since multiple spiral plates are meshed with the spiral groove, multiple top plates are brought close to the position of the rubber tube, which facilitates the needle piercing of rubber tubes of different diameters.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-5 This utility model provides a technical solution: a rubber tube needle punching device, including a base plate 1, a support plate 2 fixedly connected to the upper side of the base plate 1, a tray 11 fixedly connected to the upper side of the support plate 2, a first insertion hole 18 opened on the circumferential side of the tray 11, a placement plate 8 detachably connected to the front side of the tray 11, a second insertion hole 19 opened at the center of the circumferential side of the placement plate 8, the first insertion hole 18 and the second insertion hole 19 penetrating each other, a rubber tube passing through the first insertion hole 18 and the second insertion hole 19, and adjusting plates 10 inserted into both the left and right sides of the first insertion hole 18. The inner side is hinged with auxiliary clamping wheels 9. The front circumferential side of the placement plate 8 has multiple positioning grooves 17 arranged in a circular array. The positioning grooves 17 are provided with top plates 4 along the radial direction of the placement plate 8. The top plates 4 can slide along the positioning grooves 17. The inner side of the top plates 4 is engaged with an adjustment component located in the placement plate 8, which is used to adjust multiple top plates 4 along the radial direction of the placement plate 8 at the same time. The front side of each top plate 4 is fixedly connected with a fixing plate. The front side of each fixing plate is hinged with a piercing wheel 5. The inner side of the piercing wheel 5 is fixedly connected with multiple evenly distributed needles 6 of the same size.

[0021] First, after placing the device in a suitable position, the hose passes between the auxiliary clamping wheels 9 and enters the first insertion hole 18 of the tray 11. Then, the hose continues to move towards the second insertion hole 19. When it enters the second insertion hole 19 of the placement tray 8, the adjustment component is used to move multiple top plates 4 towards the hose simultaneously, so that the outer side of the hose contacts multiple piercing wheels 5. The hose continues to move forward, making it easier for the piercing needles 6 on the piercing wheels 5 to pierce the hose efficiently. The placement tray 8 is then fixed to the tray 11 with locking screws.

[0022] The adjusting component includes a fixed shaft 14 coaxially fixed to the placement tray 8. A large bevel gear 13 is rotatably connected to the front end of the fixed shaft 14. The large bevel gear 13 meshes with a plurality of evenly distributed small bevel gears 12. A fixed rod 7 is fixedly connected to the middle of each small bevel gear 12. One end of the fixed rod 7 extends to the outer side of the placement tray 8 and is rotatably connected to the placement tray 8. An adjusting plate is fixedly connected to the front end of the large bevel gear 13. The adjusting plate has a spiral groove 15. A plurality of spiral plates 16 are fixedly connected to the rear side of the top plate 4. The spiral plates 16 mesh with the spiral groove 15.

[0023] By rotating the fixed rod 7, the fixed rod 7 drives the small bevel gear 12 to rotate, and the small bevel gear 12 drives the large bevel gear 13 to rotate, thereby driving the adjusting plate to rotate. Since multiple spiral plates 16 are meshed with the spiral groove 15, multiple top plates 4 are driven to approach the position of the rubber tube, which facilitates needle piercing of rubber tubes of different diameters.

[0024] Each of the fixing rods 7 has a square groove.

[0025] Insert the square prism wrench into the square groove, rotate the square prism handle, and adjust the position between the multiple top plates 4.

[0026] Multiple evenly distributed assembly holes 3 are provided on the underside of the base plate 1.

[0027] After the screw passes through the assembly hole 3, the screw is threaded to the pre-placed workbench surface, which facilitates fixing the position of the base plate 1.

[0028] The puncture wheel 5 is made of hard plastic.

[0029] In use, after placing the device in a suitable position, the hose passes between the auxiliary clamping wheels 9 and enters the first insertion hole 18 of the tray 11. The hose continues to move towards the second insertion hole 19. When it enters the second insertion hole 19 of the placement tray 8, the adjusting component is used to move multiple top plates 4 towards the hose simultaneously, so that the outer side of the hose contacts multiple piercing wheels 5. The hose continues to move forward, facilitating the efficient piercing of the hose by the piercing needles 6 on the piercing wheels 5.

[0030] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
