Description

TECHNICAL FIELD

[0001] The utility model relates to the field of agricultural machinery production, and specifically relates to a multifunctional clamping device for agricultural machinery steel accessory production. BACKGROUND

[0002] Agricultural machinery, namely agricultural machinery, refers to various machinery used in the production process of crop planting and livestock breeding, and the initial processing and treatment process of agricultural and livestock products. Agricultural machinery includes agricultural power machinery, farmland construction machinery, soil tillage machinery, planting and fertilization machinery, plant protection machinery, farmland irrigation and drainage machinery, crop harvesting machinery, agricultural product processing machinery, livestock breeding machinery and agricultural transportation machinery.

The processing mechanism is provided with a collecting mechanism outside. A drilling device is arranged on one side of the processing mechanism. The collecting mechanism includes a collecting channel, which is arranged on one side of the processing mechanism. A fixed groove is fixedly connected to the inner wall of the collecting channel. A sliding block is slidably connected inside the fixed groove. A collecting frame is fixedly connected to the top of the sliding block. A partition plate is fixedly connected to the front of the collecting frame. A fixed block is fixedly connected to the front of the partition plate. A connecting box is fixedly connected to the front of the collecting channel. A spring is fixedly connected to the inner wall of the connecting box.

[0023] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0024] See also Figures 1-4A multifunctional clamping device for the production of agricultural machinery steel accessories includes a clamping mechanism 1, which includes a U-shaped frame 101. A plurality of support rollers 102 are evenly connected to the inner sides of the U-shaped frame 101 for rotation. The setting of the support rollers 102 can provide support for the steel pipe to be drilled, and also facilitate the movement of the steel pipe to be drilled. Clamps 103 are symmetrically passed through the outer sides of the support rollers 102 on both sides. The clamps 103 are used to clamp the steel pipe to be drilled. The bottom of each group of clamps 103 is fixedly connected to a moving block 105. The internal threads of the two groups of moving blocks 105 on the same side are connected to a bidirectional screw 104. The two groups of bidirectional screws 104 are both rotatably connected to the U-shaped frame 101. The bidirectional screws 104 are used to drive the corresponding two groups of moving blocks 105 and the corresponding two groups of clamps 103 to move relative to each other during rotation, thereby meeting the requirements of clamping and fixing steel pipes of different sizes.

[0025] A rubber bellows 106 is fixedly connected between the two groups of moving blocks 105 on the same side and on the opposite sides of the two groups of moving blocks 105 on the same side. The ends of the rubber bellows 106 on both sides away from the moving blocks 105 are fixedly connected to the U-shaped frame 101. Each group of rubber bellows 106 is sleeved on the outside of the bidirectional screw 104. The rubber bellows 106 are provided to shield the bidirectional screw 104 to reduce the probability of debris falling on the bidirectional screw 104 during drilling. One end of each group of bidirectional screw 104 is fixedly connected to a sprocket 107. A chain 108 is meshed and connected between the two groups of sprockets 107. The arrangement of the chain 108 and the sprocket 107 can connect the two groups of bidirectional screw 104, so that when one group of bidirectional screw 104 rotates, it can drive the other group of bidirectional screw 104 to rotate synchronously through the transmission of the two groups of sprockets 107 and the chain 108. A first stepper motor 109 is fixedly connected to one side of the outer wall of the U-shaped frame 101. The output end of the first stepper motor 109 is fixedly connected to a set of bidirectional screws 104. The first stepper motor 109 is configured to drive the bidirectional screws 104 to rotate when starting work.

[0026] The steering mechanism 2 includes a support ring 204 extending through the middle of the U-shaped frame 101. A U-shaped plate 201 is fixedly connected to the bottom middle of the U-shaped frame 101. A first hydraulic rod 202 is fixedly connected to the interior of the U-shaped plate 201. The output end of the first hydraulic rod 202 is fixedly connected to the support ring 204. The first hydraulic rod 202 is configured to drive the support ring 204 up and down during startup. Guide rods 203 are symmetrically and slidably extending through the interior of the U-shaped plate 201. Two sets of guide rods 203 are fixedly connected to the support ring 204 and are configured to guide the up and down movement of the support ring 204. Vertical plates 205 are symmetrically fixedly connected to each side of the support ring 204. Rollers 206 are rotatably connected between the two sets of vertical plates 205 on the same side. The two sets of rollers 206 provide support for the steel pipe, allowing the steel pipe to rotate with them when the rollers 206 rotate, thereby adjusting the drilling position of the steel pipe.

[0027] The outer sides of both sets of rollers 206 are fixedly connected to rubber rings 208. Multiple rubber ridges 209 are fixedly connected to the outer sides of both sets of rubber rings 208 in a circular array. The arrangement of the rubber rings 208 and rubber ridges 209 increases friction with the outer wall of the steel pipe, thereby reducing the probability of the steel pipe slipping when the steel pipe is driven to rotate. A second hydraulic rod 210 is fixed to the top of the support ring 204. The output end of the second hydraulic rod 210 is fixedly connected to a U-shaped wheel frame 211. The inner side of the U-shaped wheel frame 211 is rotatably connected to a pressure roller 212. The second hydraulic rod 210 is configured to drive the U-shaped wheel frame 211 and the pressure roller 212 up and down during startup, thereby driving the pressure roller 212 to compress the steel pipe. A second stepper motor 207 is fixedly connected to one side of a set of vertical plates 205 away from the roller 206. The output end of the second stepper motor 207 is fixedly connected to one side of the roller 206. The second stepper motor 207 is configured to drive the roller 206 to rotate when starting work.

[0028] When in use, the entire clamping device is installed under the drilling equipment. When drilling, the steel pipe to be clamped can be placed between the two sets of clamping plates 103 and pass through the support ring 204. Then, the first stepper motor 109 is started, so that the first stepper motor 109 can drive the bidirectional screw 104 on one side to rotate when starting work. The bidirectional screw 104 can drive the corresponding sprocket 107 and chain 108 to rotate when rotating, and the chain 108 can drive the sprocket 107 and the bidirectional screw 104 on the other side to rotate accordingly, so that the two sets of bidirectional screws 104 rotate synchronously, and the bidirectional screw 104 can drive the corresponding two sets of moving blocks 105 and the corresponding two sets of clamping plates 103 to move relative to each other until the two sets of clamping plates 103 clamp the steel pipe and fix it. After that, the steel pipe can be drilled. When it is necessary to adjust the drilling direction, the first stepper motor 109 can be started, so that the first stepper motor 109 drives the two The first hydraulic rod 202 is then started, so that the first hydraulic rod 202 drives the support ring 204 and the two sets of rollers 206 to move upward until the two sets of rubber rings 208 contact the steel pipe. Then the second hydraulic rod 210 is started, so that the second hydraulic rod 210 drives the U-shaped wheel frame 211 and the pressure wheel 212 to move downward until the pressure wheel 212 moves downward to contact the outer wall of the steel pipe, thereby limiting the steel pipe. Then the second stepper motor 207 can be started, so that the second stepper motor 207 can drive the corresponding roller 206 and rubber ring 208 to rotate when starting work. When the rubber ring 208 rotates, it can drive the steel pipe to rotate until the position of the steel pipe to be drilled is adjusted to the upward direction. Then the first stepper motor 109 is started again, so that the two sets of clamps 103 clamp the steel pipe again, thereby completing the adjustment of the processing direction of the steel pipe.
