Description

Technical Field

[0001] The invention relates to the technical field of fitness equipment processing equipment, and in particular to a kettlebell forming and grinding device for fitness and body shaping. Background Art

[0002] Kettlebells are generally made of cast iron, and are available in different weights, including 8 kg, 12 kg, 16 kg, 20 kg, 24 kg, 28 kg, and 32 kg. In my country, there are also lock-shaped stone locks, which are used in much the same way as kettlebells. When using kettlebells for fitness exercises, you can do various pushing, lifting, throwing, squatting, and jumping exercises. Kettlebells are generally cast using molds. Currently, the molds used to make kettlebells on the market are usually left and right molds. After the kettlebells made with the left and right molds are demolded, a joining line is left on the axial direction of the kettlebell body, and the outer wall of the cast kettlebell is generally uneven, and its outer wall needs to be fine-ground at a later stage. Therefore, a kettlebell forming and fine-grinding device for fitness shaping is introduced.

[0013] Working principle: Before using the device, place the device at the desired position, open the cover plate 3071 through the handle on the upper side of the cover plate 3071, clamp the kettlebell to be polished through the self-rotating clamp 1113, because kettlebells often have handles, the self-rotating clamp 1113 clamps the kettlebell to be polished through the handle on the kettlebell, close the cover plate 3071, start the electric push rod 1112, so that the self-rotating clamp 1113 pushes the kettlebell to be polished to close to the polishing pile 1117, there is a pit on the top of the polishing pile 1117, when the side surface of the kettlebell needs to be polished, the self-rotating clamp 1113 clamps the kettlebell to be polished and pushes the kettlebell to the upper side of the polishing pile 1117, so that the side surface of the kettlebell fits with the pit, and then the hydraulic cylinder is started 3072, so that the hydraulic cylinder 3072 pushes the grinding and fitting main cover 3073 downward, so that the grinding and fitting main cover 3073 gives downward pressure to the kettlebell to be polished, so that the side surface of the kettlebell to be polished can be close to the polishing pile 1117, thereby facilitating the subsequent polishing process to maintain a good polishing effect, and start the self-rotating clamp 1113, so that the self-rotating clamp 1113 rotates, and the self-rotating clamp 1113 can be more comprehensively and stably polished under the coverage of the pit on the upper side of the polishing pile 1117 and the concave surface on the lower side of the grinding and fitting main cover 3073, and will not accidentally detach from the polishing pile 1117 during the polishing process, thereby losing the polishing effect, and start the motor 102 to drive the main gear 103 to rotate, thereby driving the main gear ring 1111 to rotate, and at the same time At the same time, the connecting rod 1114 drives the fixed ring 1115 and the filter plate 1116 to rotate together with the main gear ring 1111, and then drives the turbine blade 1119 to rotate through the fixed rotating rod 1118, and injects clean water into the interior of the box 401 through the water inlet pipe 405, so that the water level in the box 401 is below the filter plate 1116, and the turbine blade 1119 rotates inside the water suction filter pipe 402, and the water in the box 401 is pumped into the water suction filter pipe 402 through the filter hole 403, and when it reaches a certain height, it is sprayed through the diversion flushing pipe 404 to flush and cool the surface of the kettlebell being polished, which can prevent the debris adhering to the surface of the kettlebell during polishing from affecting the polishing effect, and also prevent the kettlebell from being overheated due to polishing, which is not conducive to the collection after polishing. At the same time, the self-rotating clamping claw 1113 clamps the kettlebell that needs to be polished and revolves with the main gear ring 1111, which not only allows each surface of the kettlebell that needs to be polished to be evenly rinsed, but also allows the kettlebell to be polished more evenly to a certain extent. The rinsed water passes through the filter plate 1116 and falls back into the box 401. The filter plate 1116 filters out the debris and waste residue mixed in the rinsed water, and the water flows back into the box 401, which is convenient for subsequent continued use and can reduce the waste of water resources. When it is necessary to polish the bottom or top surface of the kettlebell, start the electric push rod 1112, so that the self-rotating clamping claw 1113 clamps the kettlebell and pushes it to a suitable position, so that the bottom or top surface of the kettlebell that needs to be polished is close to the outer periphery of the top of the polishing pile 1117.The rotation of the self-rotating clamping claw 1113 makes the bottom surface or top surface of the kettlebell to be polished close to the outer periphery of the top of the polishing pile 1117 for polishing. The arc surface of the outer periphery of the top of the polishing pile 1117 is convenient for the kettlebell to fit, so that the polishing effect is better. When the kettlebell to be polished is large in size, the hydraulic cylinder 3072 can be started to drive the main cover 3073 of the pressing and grinding fitting to be recovered, and the distance between the main cover 3073 of the pressing and grinding fitting and the polishing pile 1117 is increased, which is convenient for operating a kettlebell with a large volume. At the same time, the sliding block 3077 is pushed to slide in the middle of the strip guide rail 3075 by rotating the connecting rod 3078. When the sliding block 3077 is pushed to slide and unfold to the outside of the cover plate 3071 by rotating the connecting rod 3078, When the connecting rod 3078 is rotated to a certain extent, the adjustable fitting sub-cover 3074 is pushed downward to expand in the opposite direction, so that the grinding fitting main cover 3073 and the adjustable fitting sub-cover 3074 can cooperate, so that the downward pressing arc surface is increased, which is convenient for pressing down to fit a kettlebell with a larger volume. When grinding a larger kettlebell, the electric push rod 1112 is also required to continuously push and retract, and cooperate with the grinding fitting main cover 3073 and the adjustable fitting sub-cover 3074, so that all parts of the surface of the larger kettlebell can be fit and polished with the grinding pile 1117, so that the device can adapt to kettlebells of various sizes, making the scope of application larger. When the main gear ring 1111 rotates, it can be driven by the linkage gear 203 and the connecting rod 204 The linkage gear 202 rotates, and then drives the secondary gear ring 302 to rotate through the linkage gear 202, so that the fitting and grinding component 307 rotates together with the secondary gear ring 302 and the main gear ring 1111, so that the kettlebell to be polished can be pressed down more stably by the grinding and grinding main cover 3073 and the adjustable fitting secondary cover 3074 during the grinding process, and will not accidentally deviate. When the kettlebell to be polished is small in size, the hydraulic cylinder 3072 is started to push the grinding and grinding main cover 3073 downward to reduce the distance between the grinding and grinding main cover 3073 and the grinding pile 1117, so as to facilitate the fitting and pressing of the kettlebell with a smaller volume. At the same time, the sliding block 3074 is pulled by rotating the connecting rod 3078. The block 3077 slides in the middle of the bar guide 3075. When the rotating connecting rod 3078 pulls the slider 3077 to slide and shrink toward the axis of the cover plate 3071, the rotating connecting rod 3078 pulls the adjustable fitting sub-cover 3074 upward to retract when it reaches a certain degree, so that the adjustable fitting sub-cover 3074 will not hinder the pressing and grinding fitting main cover 3073 from pressing down on the smaller kettlebell, so that the clamping component is easy to adjust during the grinding process after clamping the kettlebell to be polished, making the grinding more flexible, and the auxiliary grinding device gives a certain pressure to the kettlebell to be polished during the grinding process, so that the kettlebell to be polished is always closely fitted to the grinding component for grinding, which improves the grinding efficiency to a certain extent.
