Description

Technical Field

[0001] This utility model relates to a surfboard tail rudder grinding device, belonging to the field of tail rudder processing technology. Background Technology

[0002] The tail fin is a fin-like device attached to the rear of the bottom of a surfboard. It is typically made of materials such as plastic, fiberglass, carbon fiber, or wood, and is one of the core components of a surfboard. The surface of the tail fin may have roughness, imperfections, or wear; the main purpose of polishing is to optimize its hydrodynamic performance and durability.

[0003] In the existing technology, the surface of the tail rudder is usually polished by using a jig to fix the base at the bottom of the tail rudder, and then using a polishing roller to polish both sides of the tail rudder. After polishing, the staff needs to remove the tail rudder and take it out, then put in the tail rudder to be polished and fix it again, and then polish it. This method has poor continuity. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a surfboard tail rudder plate grinding device, which automatically rotates out the ground tail rudder plate and rotates in the tail rudder plate to be ground for grinding, so that grinding and loading and unloading can be carried out simultaneously, and the continuity is better.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A surfboard tailboard polishing device includes: a worktable, a fixing component on the top of the worktable, a switching component between the worktable and the fixing component, a bracket installed on one side of the top of the worktable, a polishing component on the bracket, the fixing component including a hollow shaft, the hollow shaft being rotatably mounted on the top of the worktable, a housing being connected to the top of the hollow shaft via connecting pipes, a plurality of negative pressure holes being opened on the top of the housing, and the bottom of the hollow shaft being connected to a vacuum pump via a rotary joint.

[0007] Preferably, the top of the housing has a slot.

[0008] Preferably, the bottom of the housing is equipped with rollers that are rotatably connected to the worktable.

[0009] Preferably, the switching assembly includes a U-shaped frame, which is installed at the bottom of the workbench. The vacuum pump is fixedly installed at the bottom of the U-shaped frame, and a worm gear is rotatably installed between the two sides of the U-shaped frame. A worm wheel that meshes with the worm gear is installed below the outer side wall of the hollow shaft.

[0010] Preferably, the polishing assembly includes an electric cylinder mounted above one side of the bracket, with a polishing frame mounted on the output end of the electric cylinder, and two polishing rollers rotatably mounted on the top of the polishing frame.

[0011] Preferably, both ends of the grinding frame are equipped with dust collection hoods, and one end of each dust collection hood is connected to a dust collection pipe.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: the electric cylinder drives the grinding frame to extend and retract, so that the grinding rollers extend and retract. The two grinding rollers can grind both sides of the tail rudder plate respectively. Then, the worm gear rotates and drives the worm wheel to rotate, so that the hollow shaft rotates 90 degrees, so that the ground tail rudder plate is rotated out. When the ground tail rudder plate is rotated to be parallel with the grinding rollers, the grinding rollers can continue to grind the tail rudder plate. The operator can replace the ground tail rudder plate after it is rotated out. Grinding and loading and unloading are carried out simultaneously, and the continuity of grinding is better.

Detailed Implementation

[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 1-4 This utility model provides a technical solution:

[0021] A surfboard tail rudder polishing device includes: a workbench 1, a fixing component 2 on the top of the workbench 1, a switching component 3 between the workbench 1 and the fixing component 2, a bracket 4 installed on one side of the top of the workbench 1, a polishing component 5 on the bracket 4, the fixing component 2 including a hollow shaft 201, the hollow shaft 201 being rotatably mounted on the top of the workbench 1, the hollow shaft 201 being connected to a housing 203 through connecting pipes 202 on all four sides above it, the housing 203 having several negative pressure holes 204 on its top, and the bottom of the hollow shaft 201 being connected to a vacuum pump 205 through a rotary joint.

[0022] Furthermore, valves are installed on the connecting pipe 202 to achieve individual control of the four boxes 203. When loading and unloading materials, the staff can manually open and close the valves. The workbench 1 is equipped with a PLC controller, which can control the electrical components used in the device.

[0023] In this embodiment: a slot 206 is provided on the top of the housing 203.

[0024] Furthermore, the slot 206 and the base of the tail rudder plate are connected to each other, which can improve the stability of fixing the tail rudder plate.

[0025] In this embodiment: the bottom of the housing 203 is equipped with rollers that are rotatably connected to the worktable 1.

[0026] Furthermore, the rotation of the housing 203 can drive the rollers to roll on the worktable 1, thereby improving the stability of the housing 203.

[0027] In this embodiment: the switching assembly 3 includes a U-shaped frame 301, which is installed at the bottom of the workbench 1. The vacuum pump 205 is fixedly installed at the bottom of the U-shaped frame 301. A worm gear 302 is rotatably installed between the two sides of the U-shaped frame 301. A worm wheel 303 that meshes with the worm gear 302 is installed below the outer side wall of the hollow shaft 201.

[0028] Furthermore, one side of the worm gear 302 is connected to the output end of the servo motor.

[0029] In this embodiment: the grinding assembly 5 includes an electric cylinder 501, which is mounted on one side above the bracket 4. A grinding frame 502 is mounted on the output end of the electric cylinder 501, and two grinding rollers 503 are rotatably mounted on the top of the grinding frame 502.

[0030] Furthermore, a grinding motor is installed on the top of the grinding frame 502, and the output end of the grinding motor is connected to the grinding roller 503.

[0031] In this embodiment: both ends of the grinding frame 502 are equipped with dust suction hoods 6, and one end of the dust suction hood 6 is connected to a dust suction pipe 7.

[0032] Furthermore, the suction pipe 7 and the vacuum cleaner are connected by a flexible hose. During the polishing process, the vacuum cleaner can be turned on, and the suction pipe will create negative pressure in the suction hood 6 to achieve the function of suction.

[0033] The workflow of this embodiment is as follows: Insert the base of the tail rudder plate into the slot 206, then start the vacuum pump 205, and use the hollow shaft 201 and connecting pipe 202 to generate negative pressure in the negative pressure hole 204 to adsorb the bottom of the tail rudder plate and fix it in place. Then, the electric cylinder 501 drives the grinding frame 502 to extend and retract, causing the grinding roller 503 to extend and retract. The two grinding rollers 503 can then grind both sides of the tail rudder plate respectively. Then, the worm gear 302 rotates, driving the worm wheel 303 to rotate, causing the hollow shaft 201 to rotate 90 degrees, so that the ground tail rudder plate can be rotated out. Once the ground tail rudder plate is rotated to be parallel with the grinding roller 503, the grinding roller 503 can continue to grind the tail rudder plate. The operator can then replace the ground tail rudder plate that has been rotated out.
