Description

Technical Field

[0001] The utility model relates to the technical field of bicycle frame polishing, in particular to a carbon fiber bicycle frame polishing device. Background Art

[0002] Carbon fiber material has extremely high strength and extremely low specific gravity, which makes carbon fiber bicycles very light while maintaining high strength.

[0003] A carbon fiber bicycle frame generally consists of a seat tube, top tube, head tube, down tube, seat stays, and chain stays.

[0004] After the carbon fiber bicycle frame is welded and formed, its surface generally needs to be polished to improve the smoothness and aesthetics of the frame surface.

[0005] Currently, when polishing the surface of a bicycle frame, the frame is generally placed directly on the ground. Then, the operator uses a handheld polishing tool to directly polish the surface of the frame. This method of directly placing the frame on the ground causes the frame to shake during polishing, greatly reducing the anti-sway clamping stability of the carbon fiber bicycle frame during polishing. Utility Model Content

[0006] The purpose of the utility model is to solve the above-mentioned shortcomings in the prior art and to propose a carbon fiber bicycle frame polishing device.

[0007] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0008] A carbon fiber bicycle frame polishing device is designed, comprising a polishing table, a first control switch and a second control switch provided on the polishing table, a chainstay cylinder and a mounting seat provided on the polishing table, a connecting pressure seat provided on the chainstay cylinder, a stabilizing pressure block provided on the connecting pressure seat, a downtube cylinder provided on the mounting seat, a stabilizing top block provided on the downtube cylinder, and a table support leg and an arc angle surface provided on the polishing table.

[0009] The stable pressing block is provided with a pressing groove, in which a first damping layer is provided; the stable top block is provided with a top groove, in which a second damping layer is provided;

[0010] A longitudinal embedding groove is provided on the polishing table, and a left embedding groove and a right embedding groove are provided on two sides of the polishing table.

[0011] Furthermore, the rear chain fork cylinder and the stabilizing pressure block are a group, which are two groups symmetrical in front and back. The connecting pressure seat is an L-shaped structure as a whole, and the angle between the lower end surface of the stabilizing top block and the upper end surface of the polishing table is fifty degrees.

[0012] Furthermore, the pressing groove and the top groove are both arc-shaped inner grooves, the first damping layer is evenly coated along the inner groove wall of the pressing groove, and the second damping layer is evenly coated along the inner groove wall of the top groove, and the first damping layer and the second damping layer are both silicone coatings.

[0013] Furthermore, the longitudinal embedding grooves are two arc-shaped grooves arranged symmetrically in front and back, and the right embedding grooves are two symmetrical inner grooves.

[0014] Furthermore, elastic pads are provided on the inner groove walls of the longitudinal embedding groove, the left embedding groove, and the right embedding groove. The elastic pads are NBR nitrile rubber pads with a thickness of ten to fifteen centimeters.

[0015] Furthermore, the number of the platform support legs is four and they are arranged in a circle, and the platform support legs are in a Z-shaped structure as a whole.

[0016] Furthermore, a bottom supporting block is provided on the table support leg, a corrosion-resistant and anti-slip pad is provided on the bottom of the bottom supporting block, and the bottom supporting block is a trapezoidal structure as a whole.

[0017] The utility model provides a carbon fiber bicycle frame polishing device, which has the following beneficial effects:

[0018] 1.

Before polishing, the frame body is first placed upright on the polishing table, and ensures that the two chainstays of the frame body are located under the two stabilizing pressure blocks. Then, the chainstay cylinder is electronically started and the two chainstays of the frame body are stably pressed. Then, the downtube cylinder is electronically started and the downtube of the frame body is stably supported by the stabilizing top blocks. At this time, the operator can hold the handheld polishing tool to polish the surface of the frame body, thereby improving the anti-sway clamping stability of the carbon fiber bicycle frame during polishing and avoiding the shaking situation when the frame is directly placed on the ground for polishing.

[0019] 2. The utility model provides a longitudinal embedding groove, a left embedding groove, and a right embedding groove on the side wall of the polishing table, so that the operator can get closer to the stably clamped frame body, thereby increasing the effective working polishing distance between the operator and the frame body.

[0020] 3. The utility model provides Z-shaped table legs at the bottom of the polishing table to avoid collision between the operator's feet and the table legs when polishing. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0029] Reference Figure 1-6 A carbon fiber bicycle frame polishing device includes a polishing table 1, the polishing table 1 is provided with a first control switch 12 and a second control switch 13, the polishing table 1 is provided with a chainstay cylinder 3 and a mounting seat 4, the chainstay cylinder 3 is provided with a connecting pressure seat 31, the connecting pressure seat 31 is provided with a stabilizing pressure block 32, the mounting seat 4 is provided with a downtube cylinder 41, the downtube cylinder 41 is provided with a stabilizing top block 42, and the polishing table 1 is provided with a table support leg 2 and an arc angle surface 11;

[0030] A pressing groove 33 is formed on the stabilizing pressing block 32, and a first damping layer 331 is provided in the pressing groove 33. A top groove 43 is formed on the stabilizing top block 42, and a second damping layer 431 is provided in the top groove 43.

[0031] A longitudinal embedding groove 5 is provided on the polishing table 1 , and a left embedding groove 6 and a right embedding groove 7 are provided on both sides of the polishing table 1 . An arc angle surface 11 prevents the polishing table 1 from causing scratches to the operator's body due to the 90-degree angle.

[0032] All relevant power-requiring equipment are connected to an external power supply box via power cords, and the first control switch 12 and the second control switch 13 can respectively start and stop the rear chain fork cylinder 3 and the down tube cylinder 41 in real time.

[0033] The rear chain fork cylinder and the stabilizing pressure block 32 are a group, with a total of two groups symmetrical front and back. The connecting pressure seat 31 is an L-shaped structure as a whole. The lower end face of the stabilizing top block 42 and the upper end face of the polishing table 1 are at an angle of fifty degrees, so that the stabilizing top block 42 can stably support the bottom of the inclined lower tube.

[0034] The pressing groove 33 and the top groove 43 are both arc-shaped inner grooves. The first damping layer 331 is evenly coated along the inner groove wall of the pressing groove 33, and the second damping layer 431 is evenly coated along the inner groove wall of the top groove 43. The first damping layer 331 and the second damping layer 431 are both silicone coatings. The silicone coating has excellent damping friction properties. Combined with the arc-shaped inner groove structure, it further improves the stable pressing and supporting of the rear chain stay and the down tube on the frame body.

[0035] The longitudinal embedding grooves 5 are two arc-shaped grooves symmetrically arranged front to back, and the right embedding grooves 7 are two symmetrical inner grooves, which are convenient for the operator's body to enter.

[0036] An elastic cushion layer 8 is provided on the inner groove wall of the longitudinal groove 5, the left groove 6 and the right groove 7. The elastic cushion layer 8 is an NBR nitrile rubber pad with a thickness of ten to fifteen centimeters. The NBR nitrile rubber pad has excellent high-elastic cushioning properties, which improves the high-elastic cushioning comfort when in contact with the operator's body.

[0037] There are four table legs 2 arranged in a circle. The overall structure of the table legs 2 is Z-shaped. The table legs 2 are made of No. 45 steel, which has high strength and is not deformed.

[0038] The table support leg 2 is provided with a bottom support block 21, and the bottom of the bottom support block 21 is provided with a corrosion-resistant and anti-skid pad 22. The corrosion-resistant and anti-skid pad 22 is made of silicone rubber and has excellent corrosion resistance, damping and anti-skid properties, thereby improving the corrosion resistance and anti-skid properties of the bottom of the polishing table 1.

[0039] The bottom support block 21 is a trapezoidal structure as a whole, which further improves the stable support of the polishing table 1 by the four table support legs 2.

[0040] Working method: Before polishing, the frame body (which is the prior art and not shown) is first placed upright on the polishing table 1, and the two chain stays (which are the prior art and not shown) on the left side of the frame body are ensured to be located below the two stabilizing pressure blocks 32. Then, the two chain stay cylinders 3 are activated by the first control switch 12, driving the two connecting pressure seats 31 and the stabilizing pressure blocks 32 to move downward synchronously. After the two pressure grooves 33 respectively stabilize the two chain stays on the left side of the frame body, the first control switch 12 can be used to close the two chain stay cylinders 3, thereby stably pressing the left side of the frame body.

[0041] Next, the lower tube cylinder 41 is activated through the second control switch 13, driving the stabilizing top block 42 to move toward the lower tube on the frame body. When the stabilizing top block 42 stably supports the lower tube of the frame body (which is the prior art and not shown) through the top groove 33, the lower tube cylinder 41 is closed through the second control switch 13, and the frame body as a whole can be stabilized on the polishing table 1. At this time, the operator can hold the handheld polishing tool to polish the surface of the frame body (the polishing operation is the prior art), which improves the anti-sway clamping stability of the carbon fiber bicycle frame during polishing and avoids the shaking situation when it is directly placed on the ground for polishing.

[0042] Moreover, during the polishing process, the operator's body can enter the longitudinal embedding groove 5, the left embedding groove 6, and the right embedding groove 7 respectively as needed, so that the operator can get closer to the stably clamped frame body, thereby increasing the effective working polishing distance between the operator and the frame body.

[0043] Furthermore, by providing the Z-shaped table legs 2 at the bottom of the polishing table 1, the operator's feet are prevented from colliding with the table legs 2 during polishing.

[0044] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
