Description

Technical Field

[0001] The utility model belongs to the technical field of auxiliary equipment for producing grinding balls, and particularly relates to a steel ball shaping disk supporting mechanism suitable for a steel ball shaping device. Background Art

[0002] For example, the steel ball shaping device disclosed in the authorization announcement number CN 208758919 U introduces the steel ball to be shaped into the cavity to introduce the steel ball to be shaped, which is still in a high-temperature state after being rolled in the previous process, into the steel ball rolling groove of the fixed shaping ring and the steel ball rolling groove of the rotating shaping ring. In the process of the power transmission mechanism driving the rotating disk shaft, the rotating disk shaft driving the rotating disk, and the rotating disk driving the rotating shaping ring to rotate, the steel ball to be shaped is shaped and the shaped steel ball is led out of the shaping steel ball outlet cavity to the steel ball outlet. The rotating disk and the fixed disk correspond to each other. The fixed disk is set at the end of the fixed disk shaft, and the fixed disk shaft is connected and supported by the fixed disk shaft support mechanism. The rotating disk is set at the end of the rotating disk shaft, and the rotating disk shaft is connected and supported by the rotating disk shaft support mechanism. The fixed disk and the fixed shaping ring are integrally set at the end of the fixed disk shaft, which is heavy and lacks effective support at the bottom. After long-term use of the equipment, the fixed disk is prone to tilting, affecting the shaping of the steel balls. The fixed plate and the rotating plate are set correspondingly. Although the rotating plate can offset part of the gravity, it needs to stay away from the rotating plate when it is subjected to axial force, and the problem of the fixed plate being skewed cannot be effectively avoided.

[0003] The rotating disk and the fixed disk are connected by different disk shafts. During the installation and manufacturing process, errors are easily accumulated, and the concentricity of the two disks cannot be guaranteed, which causes eccentricity; and debugging is difficult.

[0025] like Figure 1-5As shown, the steel ball shaping device includes a base 1 and a transversely arranged core shaft 2. The base 1 is provided with a left core shaft support 11 and a right core shaft support 12. The left core shaft support 11 is supported on the left end of the core shaft 2, and the right core shaft support 12 is supported on the right end of the core shaft 2.

[0026] A fixed disk 31 and a rotating disk 32 are mounted on the core shaft 2, and the fixed disk 31 and the rotating disk 32 are arranged opposite to each other; a fixed shaping ring 41 and a rotating shaping ring 42 are arranged between the fixed disk 31 and the rotating disk 32, and the rotating shaping ring 42 is fixedly arranged on the rotating disk 32, and the fixed shaping ring 41 is fixedly arranged on the fixed disk 31.

[0027] Between the fixed shaping ring 41 and the rotating shaping ring 42, the fixed shaping ring 41 is provided with a fixed shaping ring steel ball rolling groove 81, and the fixed shaping ring steel ball rolling groove 81 is arranged around the circumferential direction of the fixed shaping ring 41, and the fixed shaping ring 41 is provided with a steel ball inlet 82 to be shaped and a shaping steel ball outlet 83 which are communicated with the fixed shaping ring steel ball rolling groove 81. The steel ball inlet 82 to be shaped and the shaping steel ball outlet are separated by a cavity partition 84, and the cavity partition 84 prevents the steel balls in the shaping steel ball outlet 83 from returning to the steel ball inlet 82 to be shaped.

[0028] Between the fixed shaping ring 41 and the rotating shaping ring 43, the rotating shaping ring 42 is provided with a rotating shaping ring steel ball rolling groove 86, and the rotating shaping ring steel ball rolling groove 86 is arranged opposite to the fixed shaping ring steel ball rolling groove 81, and the rotating shaping ring steel ball rolling groove 86 and the fixed shaping ring steel ball rolling groove 81 constitute a steel ball shaping cavity for the shaping steel ball.

[0029] The fixed plate 31 is provided with a steel ball outlet 85 , which is communicated with the shaping steel ball outlet 83 to enable the steel ball to be separated from the steel ball shaping cavity.

[0030] The turntable 32 is rotatably connected to the core shaft 2. A pulley 71 is provided on the turntable 32. The pulley 71 is connected to the rotating shaft of the motor through a belt. The motor drives the pulley 71 through the belt. The pulley 71 drives the turntable 32 to rotate around the core shaft 2, and the rotary shaping ring 42 rotates synchronously with the turntable 32.

[0031] In order to limit the turntable 32 and prevent the turntable 32 from deviating toward the right core shaft support 12 due to axial force, a turntable limiting ring 92 is set on the core shaft 2 at the left end of the turntable 32, and the left end of the turntable limiting ring 92 abuts against the right end of the turntable 32.

[0032] The fixed disk 31 slides back and forth along the core shaft 2. Between the fixed disk 31 and the left core shaft support 11, the core shaft 2 is fitted with a fixed disk limiting ring 91, a buffer spring and a spring push ring 5. The fixed disk limiting ring 91 is fixedly connected to the core shaft 2. The buffer spring and the spring push ring 5 are located between the fixed disk limiting ring 91 and the fixed disk 31. The buffer spring is supported between the fixed disk limiting ring 91 and the spring push ring 5. The left end of the spring push ring 5 abuts against the fixed disk 31.

[0033] Since the steel balls to be shaped rolled in the previous process are introduced into the steel ball shaping chamber through the steel ball inlet 82 to be shaped, the motor drives the rotary shaping ring 42 to rotate, and the steel balls are separated from the steel ball shaping chamber through the shaping steel ball outlet 83 to achieve the shaping of the steel balls.

[0034] During the steel ball shaping process, when the fixed shaping ring 41 is subjected to axial force, the fixed shaping ring 41 moves toward the left core shaft support 11 side, and the fixed disk 31 pushes the buffer spring, which performs buffering and vibration reduction to avoid excessive wear of the fixed shaping ring and the rotating shaping ring and prevent the motor from locking.

[0035] like Figure 1 As shown, at the bottom of the fixed disk 31 , the base 1 is provided with a support block 6 , which is supported on the bottom of the fixed disk 31 . When the fixed disk 31 slides back and forth along the core shaft 2 , the fixed disk 31 also slides on the support block 6 .

[0036] like Figure 4-5 As shown, the support block 6 is disposed between a first guide plate 61 and a second guide plate 62. The first guide plate 61 and the second guide plate 62 are parallel to each other and constitute a guide rail for the support block, along which the support block 6 slides. The first guide plate 61 is provided with a first support protrusion slot 73, and the support block 6 is provided with a first support protrusion 71 that cooperates with the first support protrusion slot 73. The second guide plate 62 is provided with a second support protrusion slot 74, and the support block 6 is provided with a second support protrusion 72 that cooperates with the second support protrusion slot 74. When the support block 6 slides along the guide rail, the first support protrusion 71 slides and displaces within the first support protrusion slot 73, and the second support protrusion 72 slides and displaces within the second support protrusion slot 74.

[0037] The first guide plate 61 and the second guide plate 62 are connected to the base plate 63. A wedge block slot 66 and a wedge block 64 are set between the base plate 63 and the support block 6. The wedge block 64 slides in the wedge block slot 66. The wedge block 64 moves back and forth between the first guide plate 61 and the second guide plate 62 along the wedge block slot 66 (sliding from the first guide plate 61 to the second guide plate 62, and sliding from the second guide plate 62 to the first guide plate 61).

[0038] The wedge block 64 is provided with a screw through hole for the adjusting bolt 65 to pass through. On the screw through hole, the wedge block 64 is provided with a nut receiving groove 75. The nut is fixedly set in the nut receiving groove 75. The nut receiving groove limits the rotation of the nut. The adjusting bolt 65 is threadedly connected to the nut in the nut receiving groove 75.

[0039] The second guide plate 62 is provided with a bolt through-hole for the passage of the adjusting bolt 65. The adjusting bolt 65 is disposed in the bolt through-hole. The adjusting bolt 65 is provided with a first bolt-limiting protrusion and a second bolt-limiting protrusion 76. The first bolt-limiting protrusion and the second bolt-limiting protrusion 76 are respectively located at both ends of the bolt through-hole. The second guide plate 62 is located between the first bolt-limiting protrusion and the second bolt-limiting protrusion 76, thereby achieving a rotational connection between the adjusting bolt 65 and the second guide plate 62. When the adjusting bolt 65 is rotated, the nut on the adjusting bolt 65 moves, and the wedge block 64 follows the nut and slides within the wedge block slot 66, thereby achieving the adjustment bolt 65 driving the wedge block 64 to move back and forth between the first guide plate 61 and the second guide plate 62.

[0040] The end surface of the wedge block 64 that contacts the support block 6 is a first inclined surface 641 (the wedge block 64 is a tapered structure with the head end height lower than the tail end height). The end surface of the support block 6 that contacts the wedge block 64 is a second inclined surface 642, which mates with the first inclined surface 641. When the adjusting bolt 65 drives the wedge block 64 to slide within the wedge block slot 66, the wedge block 64 pushes the support block 6 along the guide rail away from the base plate 3, and is supported on the bottom of the fixed plate 31.

[0041] The above embodiments do not limit the present invention in any way, and any technical solutions obtained by equivalent replacement or equivalent transformation fall within the protection scope of the present invention.
