Description

Technical Field

[0001] The present invention relates to the field of barbell processing, and more particularly to a barbell processing device. Background Art

[0002] A barbell is a common exercise tool in daily life. It consists of a barbell bar and barbell plates. Barbell plates are generally cast from cast iron. The cast barbell plates have burrs on the outer periphery, so they need to be polished.

[0003] A Chinese patent with authorization announcement number CN216633691U discloses a grinding device for the production of dumbbell barbell plates, providing a technical solution. When the outer periphery of the barbell plate needs to be polished, several barbell plates of the same specification are sequentially mounted on the mounting shaft, and the barbell plate on one side is against the limit plate. After the installation is completed, the positioning plate is mounted on the mounting shaft to against the barbell plate on the other side. The positioning rods connected to the side of the positioning plate are sequentially inserted into the positioning holes on several barbell plates. After the positioning plate is fixed to the mounting shaft, the position of the barbell plate and the mounting shaft is fixed and will not rotate or move relative to each other. The hydraulic cylinder drives the grinding plate at the bottom of the mounting block to move downward until it contacts the top of the barbell plate. The drive motor drives the mounting shaft to rotate, driving the barbell plate to rotate, and the grinding plate can grind the outer periphery of the barbell plate.

[0004] Although the above patent can achieve the grinding of the outer periphery of the barbell plate, a keyway is still left in the center of the barbell plate for fixing with the horizontal bar. Therefore, after the barbell plate is cast, burrs are prone to appear at the keyway. Since the barbell needs to be replaced manually during exercise, it is easy to scratch the palm of the exerciser. The above patent can only grind the outer periphery of the barbell plate, but cannot grind the keyway of the barbell plate. The grinding effect is poor, which affects the use of the barbell plate.

[0005] For this reason, a barbell processing equipment is proposed. Summary of the Invention

A pressure ring 3 is elastically connected to the pressure ring 3, and an insert plate 26 is provided on the inner side of the pressure ring 3, and the insert plate 26 is inserted into the lower end surface of the fixed plate 35; a disc groove 21 is provided at the center position inside the processing table 1, and the chassis 2 is rotatably connected in the disc groove 21, and two plate grooves 22 are provided in an annular and equidistant manner on the inner side of the chassis 2, and slides 23 of L-shaped structures are respectively inserted in the plate grooves 22, and the two slides 23 are provided with notches 24 for inserting the insert plate 26 on the sides corresponding to each other, and the two slides 23 are fixedly connected to the grinding blocks 25 on the sides away from each other; a movable plate 37 is inserted in the fixed plate 35, and a socket 38 for inserting the insert plate 26 is provided at the center position of the movable plate 37, and a motor 17 is fixedly connected to the center position of the upper end surface of the hanging plate 14, and the output shaft of the motor 17 passes through the hanging plate 14 and is fixedly connected to the upper end surface of the fixed plate 35;

[0038] The cross section of the fixed plate 35 is a groove structure that matches the movable plate 37, and the upper end surface of the fixed plate 35 is symmetrically fixedly connected to two L-shaped limit blocks 36 of the fixed plate 35. The lower end surface of the hanging plate 14 is provided with a limit groove 39 of an annular structure that matches the limit block 36. The center position of the front and rear sides of the inserting plate 26 is fixedly connected to the baffle 28, and the upper end surface of the baffle 28 is fixedly connected to the limit rod 27 respectively. The lower end surface of the fixed plate 35 is symmetrically provided with two rod holes 29 that match the limit rod 27 in the front and rear directions, and the upper end surface of the limit rod 27 is elastically connected to the inner top surface of the rod hole 29 by a spring. The outer side surface of the annular insert ring 32 is provided with a groove 33 of an annular groove structure near the upper end position. The inner side surface of the rotating disk 34 is rotatably connected to the groove 33 through an annular protrusion. The upper end surface of the pressure ring 3 is provided with a slot 31 that matches the insert ring 32, and the lower end surface of the insert ring 32 is elastically connected to the inner bottom surface of the slot 31 by six springs distributed in an annular manner.

[0039] By adopting the above technical solution, the barbell piece to be polished is placed on the upper end surface of the processing table 1, and the grinding blocks 25 on the two slides 23 are located inside the key grooves of the barbell piece. Then, the two hydraulic push rods 16 are started to synchronously push the hanging plate 14 downward to drive the pressure ring 3 close to the barbell piece. Since the insert ring 32 is elastically connected to the slot 31 on the upper end surface of the pressure ring 3 through a spring, when the lower end surface of the pressure ring 3 just contacts the barbell piece, as the hanging plate 14 continues to descend, the insert ring 32 is gradually inserted into the slot 31, thereby applying pressure to the pressure ring 3, and then pressing the barbell piece tightly against the upper end surface of the processing table 1 to prevent the pressure ring 3 from being polished during the polishing process. During the grinding process, the barbell plate shakes and affects the grinding effect. As the insert ring 32 is gradually inserted into the slot 31, the lower half of the insert plate 26 below the fixed plate 35 is gradually inserted into the notch 24 between the two slide plates 23. Since the lower half of the insert plate 26 is an isosceles trapezoidal structure, the insert plate 26 gradually squeezes the two slide plates 23 during its gradual descent, thereby driving the two grinding blocks 25 to gradually approach the inner wall of the keyway of the barbell plate. As the hanging plate 14 continues to descend, the baffle 28 on the insert plate 26 contacts the upper end surface of the barbell plate, so that the insert plate 26 no longer descends. At this time, the two grinding blocks 25 are just The locking mechanism 35 is locked and the locking mechanism 35 is unlocked, so that the locking mechanism 35 is unlocked and the winch 30 is unlocked. The rotation of the fixed plate 35 ensures the stable rotation of the fixed plate 35, thereby ensuring the grinding quality of the barbell plate. The rotation of the fixed plate 35 drives the turntable 34 to rotate. Since the turntable 34 is rotatably connected to the card slot 33 on the insert ring 32, it is ensured that the insert ring 32 and the pressure ring 3 do not rotate. When the fixed plate 35 rotates, it also drives the movable plate 37 to rotate, thereby driving the insert plate 26 to rotate. Since the chassis 2 is rotatably connected to the disk slot 21 inside the processing table 1, it drives the slide plate 23 to rotate, so that the grinding block 25 can rotate around the inner wall of the keyway of the barbell plate, thereby completing the grinding of the barbell plate keyway and preventing the burrs in the keyway from scratching the user.

[0040] like Figure 5 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10As shown, the left end of the movable plate 37 is fixedly connected to the pressure plate 4, and the right side of the pressure plate 4 is symmetrically fixedly connected to two insertion rods 41 on the front and rear sides of the movable plate 37. The left side of the fixed plate 35 is provided with a socket 42 for inserting the insertion rod 41, and the right end face of the insertion rod 41 is elastically connected to the inner wall of the socket 42 through a spring. The right side of the pressure plate 4 is symmetrically slidably connected to two clamping plates 43 up and down, and a sanding belt 44 is fixedly connected between the two clamping plates 43 by bolts. The right side of the fixed plate 35 is symmetrically provided with two slide rails 45 with a T-shaped cross-section up and down, and the slide rails 45 are respectively slidably connected with frame plates 46 matching the slide rails 45, and the sides of the two slides 23 away from each other are elastically connected to the sides of the two slide rails 45 away from each other through springs.

[0041] By adopting the above technical solution, since the upper end of the insert plate 26 is a right-angled trapezoidal structure, and the hypotenuse of the right-angled trapezoidal structure at the upper end of the insert plate 26 faces right, and the hypotenuse on the inner side of the socket 38 also faces right, the movable plate 37 is continuously pushed to the right during the process of the upper end of the insert plate 26 gradually being inserted into the socket 38, thereby driving the pressure plate 4 to gradually approach the outer peripheral position of the barbell plate and driving the insertion rod 41 to gradually compress the spring in the socket 42, thereby causing the sanding belt 44 to gradually contact the outer periphery of the barbell plate. As the insert plate 26 continues to enter the socket 38, after the sanding belt 44 contacts the outer periphery of the barbell plate, the upper and lower ends of the sanding belt 44 will gradually approach under the action of tension, thereby driving the two frame plates 46 along the sliding The rail 45 gradually approaches. Since the outer cross-section of the barbell plate is a hemispherical structure, burrs are easily generated at the upper and lower edges of the outer periphery of the barbell plate after casting is completed. Therefore, it is necessary to wrap the edge line of the outer periphery of the barbell plate with the sanding belt 44 before stopping pushing the hanging plate 14 downward. In the process of the motor 17 driving the fixed plate 35, the sanding belt 44 can rotate around the outer periphery of the barbell plate, and then the burrs on the outer periphery and the two edge lines of the barbell plate are also polished away, so that the polishing mechanism completes the polishing of the key groove position of the barbell plate and also completes the polishing of the outer periphery of the barbell plate, thereby improving the processing efficiency. The sanding belt 44 is fixedly connected to the two splints 43 by bolts, which is convenient for subsequent replacement of the sanding belt 44.

[0042] like Figure 2 、 Figure 5 、 Figure 6 、 Figure 10 As shown, two collecting boxes 5 are symmetrically fixedly connected to the upper and lower rear sides of the pressure plate 4, and the rear sides inside the collecting boxes 5 are fixedly connected to electromagnets 51. The left sides of the collecting boxes 5 near the bottom are slidably plugged with receiving slots 52. The rear sides of the two collecting boxes 5 are commonly fixedly connected to a conductive plate 53, and the conductive plate 53 is electrically connected to the two electromagnets 51 respectively. The lower end face of the hanging plate 14 is embedded with an annular electrode plate 54 fixedly connected.

[0043] By adopting the above technical solution, in the process of the pressing plate 4 approaching the barbell plate, the conductive plate 54 gradually approaches the electrode plate 53. When the sanding belt 44 wraps around the outer periphery of the barbell plate, the upper end of the conductive plate 53 contacts the lower end surface of the electrode plate 54, and the electrode plate 54 is connected to the external power supply, thereby energizing the conductive plate 53, causing the electromagnet 51 to be energized and generate magnetism. Since the barbell plate is made of cast iron, the burrs on the outer periphery of the barbell plate will produce iron filings during the sanding process of the sanding belt 44. Since the electromagnet 51 can rotate synchronously with the sanding belt 44, the generated iron filings can be adsorbed on the electromagnet 51 to prevent the iron filings from flying everywhere. When the sanding is completed, the two hydraulic push rods 16 are started to drive the hanging plate 14 to reset as mentioned above, so that the upper end of the plug plate 26 gradually leaves the socket 38. Since the insertion rod 41 on the pressing plate 4 is elastically connected to the socket 42 on the left side of the fixed plate 35 by a spring, when the movable plate 37 gradually loses its limit, the spring in the socket 42 gradually resets, thereby driving the insertion rod When the grinding belt 44 gradually leaves the barbell plate, the two frame plates 46 move away from each other under the pull of the spring inside the slide rail 45, thereby restoring the grinding belt 44. At the same time, the inserting plate 26 between the two slides 23 moves away as the hanging plate 14 rises, causing the slide 23 to reset under the elastic force of the spring inside the plate groove 22, thereby preparing for the grinding of the next barbell plate.

[0044] Instructions for use: Place the barbell piece to be polished on the upper end surface of the processing table 1, then start the two hydraulic push rods 16 to synchronously push the hanging plate 14 downward to drive the pressure ring 3 close to the barbell piece, so that the lower half of the inserting plate 26 under the fixed plate 35 is gradually inserted into the notch 24 between the two slides 23, thereby driving the two grinding blocks 25 to gradually approach the inner wall of the key groove of the barbell piece, and at the same time drive the limit rod 27 to gradually insert into the rod hole 29 of the lower end surface of the fixed plate 35, so that the upper end of the inserting plate 26 is gradually inserted into the socket 38 at the center position of the movable plate 37, and drive the sanding belt 44 to wrap around the outer periphery of the barbell piece, then start the motor 17 to drive the fixed plate 35 to rotate, thereby driving the grinding block 25 to polish the inner wall of the key groove at the center position of the barbell piece while driving the sanding belt 44 to polish the outer periphery of the barbell piece, thereby improving the polishing effect of the barbell piece and ensuring the quality of the barbell piece.
