Description

Technical Field

[0001] This utility model relates to the field of vibration platform technology, and in particular to a high-frequency vibration molding device. Background Technology

[0002] In material forming and many industrial production fields, the quality and performance of products largely depend on the forming process. Taking concrete products as an example, the density of their internal structure directly affects key performance indicators such as strength and durability. Generally, high-frequency vibration devices are used to vibrate the concrete mold, making the concrete filling inside the mold more compact and uniform, thereby improving product quality.

[0003] In the existing technology, existing vibration molding devices can adjust the vibration frequency by adjusting the speed of the motor. However, when adjusting the vibration amplitude, it is generally necessary for the operator to use tools such as wrenches to adjust the angle between the two eccentric counterweight wheels of the vibration motor, thereby adjusting the degree of eccentricity between the center of gravity of the two eccentric counterweight wheels and the output end of the motor. Such adjustment is very inconvenient. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-frequency vibration molding device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A high-frequency vibration molding device includes a worktable. A guardrail is fixedly connected to the top of the worktable. A first fixed plate is fixedly connected to one side of the middle of the bottom of the worktable, and a second fixed plate is fixedly connected to the other side of the middle of the bottom of the worktable. A motor is fixedly connected to the outside of the first fixed plate. A first U-shaped component is fixedly connected to the output end of the motor through the first fixed plate. A first connecting rod is rotatably connected to the inside of the first U-shaped component. A sliding rod is slidably fitted on the bottom of the second fixed plate, and the sliding rod is coaxial with the output end of the motor. A circular hole adapted to the sliding rod is opened on the bottom of the second fixed plate. A second U-shaped component is rotatably connected to the end of the sliding rod near the first fixed plate, and a second connecting rod is rotatably connected to the inside of the second U-shaped component. The second connecting rod is the same length as the first connecting rod, and the end of the first connecting rod near the second U-shaped component is rotatably connected through a rotating shaft. Counterweights are fixedly connected to both ends of the rotating shaft. By adjusting the distance between the second U-shaped component and the first U-shaped component, the eccentricity between the counterweights and the motor output shaft is adjusted, thereby adjusting the vibration amplitude of the worktable.

[0007] Preferably, a third fixed plate is also fixedly connected to the bottom of the workbench near the second fixed plate. A lead screw is rotatably connected to the side of the third fixed plate near the second fixed plate, and the lead screw is rotatably connected to one side of the second fixed plate. The position of the second U-shaped part can be adjusted by rotating the lead screw.

[0008] Preferably, a screw block is screwed onto the circumferential surface of the lead screw, and a lead screw nut that matches the lead screw is fixedly sleeved on the top of the screw block, and the bottom of the screw block is fixedly connected to one end of the slide rod.

[0009] Preferably, the end of the lead screw near the third fixed plate is fixedly connected to a sleeve through the third fixed plate, and a hexagonal sliding hole is opened on the side of the sleeve away from the third fixed plate. A cover is fixedly connected to the end of the sleeve away from the third fixed plate. A pull rod is slidably fitted on the cover. A round hole adapted to the pull rod is opened in the middle of the cover. An iron hexagonal block is fixedly connected to the end of the pull rod located inside the hexagonal sliding hole. The iron hexagonal block is adapted to the hexagonal sliding hole. A magnet is fixedly connected to the inner end of the hexagonal sliding hole.

[0010] Preferably, a crank is fixedly connected to one end of the outer side of the pull rod, and a stop bar is fixedly connected to the end of the crank near the pull rod. A disc is fixedly connected to the third fixing plate near the sleeve, and multiple slots are equally spaced on the end of the disc near the stop bar. The slots are adapted to the stop bar. The arrangement of the stop bar and the slots ensures that the crank cannot rotate when it is not pulled out.

[0011] Preferably, a support mechanism is provided at each of the four corners of the bottom of the workbench. The support mechanism includes a positioning rod fixedly connected to the corner of the bottom of the workbench. A limit plate is fixedly connected to the bottom of the positioning rod, and a top plate is fixedly connected to the top of the positioning rod. A U-shaped frame is slidably sleeved in the middle of the positioning rod. A round hole adapted to the positioning rod is opened in the middle of the top of the U-shaped frame. Springs are sleeved at the top and bottom of the positioning rod.

[0012] Preferably, the bottoms of the four U-shaped frames are fixedly connected to the same base.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. By employing a motor, a first connecting rod, a counterweight, a second U-shaped component, a screw block for the second connecting rod, a lead screw, and a crank handle, the crank handle drives the lead screw to rotate, thereby adjusting the distance between the screw block, the sliding rod, the second U-shaped component, and the first U-shaped component. This, in turn, adjusts the distance between the two counterweights and the motor output shaft, thus regulating the vibration amplitude of the worktable. This method is convenient and quick, requiring no additional tools or laborious adjustments, effectively solving the problem of inconvenient amplitude adjustment mentioned in the background technology. It allows operators to quickly and accurately adjust the vibration amplitude of the worktable, adapting to different materials and process requirements, and significantly improving the versatility and production efficiency of the molding device.

[0015] 2. By using the hexagonal iron block of the crank handle, hexagonal sliding hole, sleeve, slot and stop bar, the stop bar and slot are engaged when the crank handle is not pulled out, so that the lead screw will not rotate. This ensures that the second U-shaped part will not change position due to vibration during operation, thus preventing changes in amplitude and ensuring the stability of the device.

The bottom of the second fixing plate 5 is provided with a round hole that matches the slide rod 501. The end of the slide rod 501 near the first fixing plate 4 is rotatably connected to the second U-shaped part 503. The inner side of the second U-shaped part 503 is rotatably connected to the second connecting rod 504. The second connecting rod 504 is the same length as the first connecting rod 403. The end of the first connecting rod 403 that is close to the second U-shaped part 503 is rotatably connected through a rotating shaft. Both ends of the rotating shaft are fixedly connected to counterweights 404.

[0025] In this utility model, a third fixing plate 6 is fixedly connected to the bottom of the workbench 3 near the second fixing plate 5. A lead screw 601 is rotatably connected to the side of the third fixing plate 6 near the second fixing plate 5, and the lead screw 601 is rotatably connected to the side of the second fixing plate 5.

[0026] In this utility model, a screw block 502 is screwed onto the circumferential surface of the lead screw 601, and a lead screw nut that is compatible with the lead screw 601 is fixedly sleeved on the top of the screw block 502. The bottom of the screw block 502 is fixedly connected to one end of the slide rod 501. The position of the counterweight block 404 is adjusted by moving the slide rod 501 with the screw block 502.

[0027] In this utility model, a sleeve 602 is fixedly connected to one end of the lead screw 601 near the third fixed plate 6, passing through the third fixed plate 6. A hexagonal sliding hole 603 is provided on the side of the sleeve 602 away from the third fixed plate 6, and a cover 608 is fixedly connected to the other end of the sleeve 602 away from the third fixed plate 6. A pull rod 604 is slidably mounted on the cover 608. A round hole that matches the pull rod 604 is provided in the middle of the cover 608. An iron hexagonal block 605 is fixedly connected to one end of the pull rod 604 inside the hexagonal sliding hole 603, and the iron hexagonal block 605 matches the hexagonal sliding hole 603. A magnet is fixedly connected to one end of the inner side of the hexagonal sliding hole 603. The setting of the magnet and the iron hexagonal block 605 ensures that the crank handle 607 will not slip out when not manually pulled, thus ensuring that the stop rod 606 and the slot 701 are always engaged.

[0028] In this utility model, a crank 607 is fixedly connected to one end of the pull rod 604, and a stop bar 606 is fixedly connected to one end of the crank 607 near the pull rod 604.

Through the setting of the slots 701 and the stop bar 606, the crank 607 will not rotate when it is not pulled out, thereby ensuring the stability of the device.

[0029] In this utility model, a support mechanism 2 is provided at each of the four corners of the bottom of the workbench 3. The support mechanism 2 includes a positioning rod 202 fixedly connected to the corner of the bottom of the workbench 3. A limit plate 203 is fixedly connected to the bottom of the positioning rod 202, and a top plate 204 is fixedly connected to the top of the positioning rod 202. A U-shaped frame 201 is slidably sleeved in the middle of the positioning rod 202. A round hole adapted to the positioning rod 202 is opened in the middle of the top of the U-shaped frame 201. Springs 205 are sleeved at the top and bottom of the positioning rod 202. Through the setting of the support mechanism 2, the workbench 3 can vibrate in the vertical direction.

[0030] In this utility model, the bottoms of the four U-shaped frames 201 are fixedly connected to the same base 1.

[0031] Working Principle: When using this device, the mold or other product requiring vibration is placed on top of the worktable 3. The motor 401 is started, causing it to rotate along the first connecting rod 403, the second connecting rod 504, and the counterweight 404. Since the counterweight 404 is not on the rotation axis of the motor 401's output end, the worktable 3 vibrates at a high frequency. Under the action of the support mechanism 2, the worktable 3 vibrates continuously up and down. The multiple springs 205 provide cushioning for the worktable 3 and also provide space for its vertical vibration. To adjust the vibration amplitude of the worktable 3, the eccentricity between the counterweight 404 and the output end of the motor 401 is adjusted by moving the crank handle 607 towards... Pulling outwards separates the iron hexagonal block 605 from the magnet. At this time, the stop bar 606 separates from the slot 701, and the crank handle 607 can rotate. The crank handle 607 drives the rotation of the lead screw 601, and the screw block 502 moves with the slide bar 501. When the second U-shaped part 503 moves closer to one side of the first U-shaped part 402, the eccentricity of the counterweight 404 increases. When the second U-shaped part 503 moves in the opposite direction, the eccentricity of the counterweight 404 decreases, thus reducing the vibration amplitude of the worktable 3. The arrangement of the stop bar 606, the slot 701, and the magnet ensures that when the crank handle 607 is not pulled out, the lead screw 601 will not cause the position of the screw block 502 to change due to the vibration of the equipment.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
