Polishing equipment for sports equipment processing

Abstract

This invention provides a polishing device for processing sports equipment, relating to the technical field of polishing equipment. It includes a polishing machine and dumbbell plates. Two first fixed frames and two second fixed frames are fixedly installed near the upper rear side of the polishing machine. A rotating frame is positioned between the two second fixed frames. A drive shaft is fixedly installed at the center of the rotating frame. The left side of the drive shaft passes through the second fixed frames and the two first fixed frames. Rotation of the drive shaft drives the rotating frame and the drive shaft to rotate. The rotation of the rotating frame drives multiple sets of polishing plates to rotate, polishing the surface of the dumbbell plates. The drive shaft rotates at a fixed positioning point. Since the positioning point remains stationary, when the drive shaft slides outside the positioning point via a surface sliding rail, it undergoes a back-and-forth displacement. At this time, the rotating frame drives multiple polishing plates to rotate and move back and forth simultaneously, thus enabling more comprehensive polishing of the dumbbell plate surface. Furthermore, the lateral rotation polishing efficiency is higher.

[0009] The axle up and down groove at two ends embeds respectively in two guide rails up and down of being made up of the groove on the attachment piece, and the tooth on the attachment piece is meshed with tooth on upper sprocket wheel, the lower sprocket.

[0010] Preferably, a polishing sheet is provided on the surface of each of the cross-shaped brackets, and two rotating shaft frames are fixedly installed on the side of each of the polishing sheets close to the cross-shaped bracket, a rotating shaft is fixedly installed between the two rotating shaft frames, and the rotating shaft rotates through the cross-shaped bracket, and at least two springs are fixedly installed on the side of each of the polishing sheets close to the cross-shaped bracket, and the end of each of the springs is in contact with the surface of the rotating frame, and a rubber pad is fixedly installed on the side wall of the spring away from the spring, and the polishing sheet is used for polishing dumbbell sheets.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] In the present invention, the rotation of the transmission shaft drives the rotating frame and the driving shaft to rotate, and the rotation of the rotating frame drives the multiple groups of polishing sheets to rotate, and the multiple groups of polishing sheets rotate to polish the surface of the dumbbell sheet. The driving shaft rotates on the positioning point, and the positioning point is fixed. Therefore, when the driving shaft slides outside the positioning point through the sliding rail on the surface, it will move forward and backward. At this time, the rotating frame will drive the multiple polishing sheets to rotate and move forward and backward at the same time, so that the surface of the dumbbell sheet can be polished more comprehensively, and the lateral rotation polishing efficiency is higher.

[0013] In the present invention, the second transmission disk drives the first transmission disk to rotate through the transmission belt, the rotation of the first transmission disk drives the two outer sleeves to rotate, the rotation of the two outer sleeves drives the transmission shaft to rotate through the two internal inner blocks, the rotation of the transmission shaft drives the drive shaft to rotate, the drive shaft rotates outside the positioning point through the sliding rail, and is driven by the positioning point to move horizontally, the two outer sleeves can keep the transmission shaft rotating stably inside, thereby realizing the effect of multi-directional polishing and improving the diversity of polishing.

[0014] In the present invention, the rotation of the rotating frame drives multiple polishing plates to rotate. In the initial state, the polishing plates are all supported by springs and are at an inclined angle. When the polishing plates contact the dumbbell plates, the force on the polishing plates gradually changes the angle. The polishing plates rotate outside the cross-shaped bracket through the rotating shaft, and the polishing angle of the dumbbell plates is changed at the same time, thereby improving the polishing angle of the dumbbell plates and maintaining a close fit with the dumbbell plates, thereby ensuring that the dumbbell plates are polished comprehensively and reducing the probability of dumbbell plates being missed.

[0015] In the present invention, the bolts are rotated and disassembled, and then the cross-shaped bracket is slid out of the cross slide groove, and then the polishing sheet and the cross-shaped bracket are replaced, and then reset and installed after the replacement is completed. Each polishing sheet on the surface of the rotating frame can be disassembled, so the surface of the rotating frame can be selected according to the polishing requirements. The number of polishing sheets and the distance between them can be selected to be installed, thereby improving the functionality of polishing different dumbbell sheets.

[0016] In the present invention, the rotation of the support frame will drive the lower fixed frame and the dumbbell plate to rotate. When the dumbbell plate rotates counterclockwise, the upper half of the dumbbell plate gradually contacts multiple polishing plates, thereby realizing automatic polishing of different parts. Since the first gear is fan-shaped, the angle of the support frame driven by the first gear is limited. When the first gear rotates away from the second gear, the torsion spring between the transmission rod and the third fixed frame drives the support frame to rotate and reset, thereby realizing repeated polishing of multiple parts of the dumbbell plate, greatly improving the ability to polish dumbbell plates of different specifications, and at the same time using the same motor to drive the rotating frame and the support frame to operate simultaneously, thereby improving the coordination between the two.

In the initial state, the lower half of the dumbbell piece 27 is connected to the rotating frame 28. The surface parts fit together, and the polishing sheet 4 is subjected to a force that gradually changes its angle. The polishing sheet 4 rotates outside the cross-shaped bracket 45 through the rotating shaft 43, and at the same time, the polishing angle of the dumbbell sheet 27 is changed, thereby improving the polishing angle of the dumbbell sheet 27, and can maintain a close fit with the dumbbell sheet 27, thereby ensuring that the dumbbell sheet 27 is polished comprehensively and reducing the probability of the dumbbell sheet 27 being missed.

[0031] Working principle:

[0032] In the first step, when the user polishes the dumbbell plate 27, first pull out the upper fixing frame 25 from the two lower fixing frames 24, put the dumbbell plate 27 on the support frame 2, and at the same time put the dumbbell plate 27 outside the fixing column 21, and then insert the plugs 26 at both ends of the upper fixing frame 25 into the two lower fixing frames 24. At this time, the support frame 2 is fixed, and the motor 17 is started. The operation of the motor 17 drives the second transmission plate 31 and the first transmission plate 3 to rotate through the output shaft. The rotation of the first transmission plate 3 drives the transmission shaft 33 to rotate through the two outer shaft sleeves 36, and the transmission shaft 3 The rotation of the rotating frame 28 and the driving shaft 34 drives the rotating frame 28 to rotate, and the rotation of the rotating frame 28 drives the multiple groups of polishing sheets 4 to rotate. The multiple groups of polishing sheets 4 rotate to polish the surface of the dumbbell sheet 27. The driving shaft 34 rotates on the positioning point 15, and the positioning point 15 is fixed. Therefore, when the driving shaft 34 slides outside the positioning point 15 through the sliding rail 35 on the surface, it will move forward and backward. At this time, the rotating frame 28 drives the multiple polishing sheets 4 to rotate and move forward and backward at the same time, so that the surface of the dumbbell sheet 27 can be polished more comprehensively, and the lateral rotation polishing efficiency is higher.

[0033] In the second step, when the motor 17 drives the second transmission disc 31 to rotate through the output shaft, the second transmission disc 31 drives the first transmission disc 3 to rotate through the transmission belt 32, and the rotation of the first transmission disc 3 drives the two outer sleeves 36 to rotate, and the two outer sleeves 36 rotate through the two inner blocks 37 inside to drive the transmission shaft 33 to rotate, and the rotation of the transmission shaft 33 drives the driving shaft 34 to rotate, and the driving shaft 34 rotates outside the positioning point 15 through the sliding rail 35, and is driven by the positioning point 15 to move horizontally, and the two outer sleeves 36 can keep the transmission shaft 33 rotating stably inside, so as to achieve the effect of multi-directional polishing and improve the diversity of polishing;

[0034] When the rotating frame 28 rotates, the rotating frame 28 rotates and drives the multiple polishing sheets 4 to rotate. In the initial state, the polishing sheets 4 are all supported by the springs 41, and the polishing sheets 4 are at an inclined angle. When the polishing sheets 4 contact the dumbbell sheets 27, the polishing sheets 4 are gradually forced to change their angles. The polishing sheets 4 rotate outside the cross-shaped bracket 45 through the rotating shaft 43, and the polishing angle of the dumbbell sheets 27 is changed at the same time, thereby improving the polishing angle of the dumbbell sheets 27 and maintaining a close fit with the dumbbell sheets 27, thereby ensuring that the dumbbell sheets 27 are polished comprehensively and reducing the probability of the dumbbell sheets 27 being missed.

[0035] When the polishing sheet 4 needs to be replaced, the user rotates the bolt 46 to remove it, then slides the cross bracket 45 out of the cross slide 29, and then replaces the polishing sheet 4 and the cross bracket 45. After the replacement is completed, they are reset and installed. Each polishing sheet 4 on the surface of the rotating frame 28 can be removed. Therefore, the surface of the rotating frame 28 can be selected according to the polishing requirements. The number of polishing sheets 4 and the distance between them can be selected to improve the functionality of polishing different dumbbell sheets 27.

[0036] The third step is that when the output shaft of the motor 17 rotates, it will also drive the first gear 19 to rotate. When the first gear 19 rotates and meshes with the second gear 23, the first gear 19 will drive the second gear 23 to rotate. The rotation of the second gear 23 will drive the support frame 2 to rotate. The rotation of the support frame 2 will drive the lower fixed frame 24 and the dumbbell piece 27 to rotate. When the dumbbell piece 27 rotates counterclockwise, its upper half gradually contacts a plurality of polishing sheets 4, thereby achieving automatic polishing of different parts. Since the first gear 19 is fan-shaped, the angle at which the first gear 19 drives the support frame 2 is limited. When the first gear 19 rotates away from the second gear 23, the torsion spring between the transmission rod 22 and the third fixed frame 16 drives the support frame 2 to rotate and reset, thereby achieving repeated polishing of multiple parts of the dumbbell piece 27, greatly improving the ability to polish dumbbell pieces 27 of different specifications. At the same time, the same motor 17 is used to drive the rotating frame 28 and the support frame 2 to operate simultaneously, thereby improving the coordination between the two.

Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.
