Description

Technical Field

[0001] The utility model relates to the technical field of flange production equipment, in particular to a positioning mechanism for flange production that can improve clamping flexibility. Background Art

[0002] In the flange production industry, clamping and positioning are crucial links in the processing process, directly affecting the processing accuracy, production efficiency, and product quality of products. Traditional flange clamping and positioning mechanisms often have some deficiencies.

[0003] The design of traditional fixtures is relatively fixed and difficult to adapt to flanges of different sizes and shapes. This requires the production line to be equipped with various specifications of fixtures, which not only increases the manufacturing cost but also increases the complexity and time cost of fixture replacement, reducing the flexibility of the fixture. Although there are some detachable fixtures through bolts and other methods, this positioning method is prone to wire slipping, wear, or loosening of the bolts due to rust after long-term use, resulting in a decrease in positioning accuracy and a reduction in its practicality. Therefore, we propose a positioning mechanism for flange production that can improve clamping flexibility to solve the above problems. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a positioning mechanism for flange production that can improve clamping flexibility, which solves the problems in the prior art that traditional fixtures are difficult to adapt to flanges of different sizes and shapes. This requires the production line to be equipped with various specifications of fixtures, which not only increases the manufacturing cost but also reduces the flexibility of the fixture. Although there are some detachable fixtures through bolts and other methods, this positioning method is prone to wire slipping, wear, or loosening of the bolts due to rust after long-term use, resulting in a decrease in positioning accuracy and a reduction in its practicality.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A positioning mechanism for flange production that can improve clamping flexibility includes a mounting plate. Two clamping plates are symmetrically arranged inside the mounting plate. On one side of each of the two clamping plates away from each other, a clamping block is fixedly connected. Two connecting rods are symmetrically arranged inside the mounting plate, and the connecting rods are L-shaped. At one end of each of the two connecting rods, a clamping groove adapted to the clamping block is opened. A clamping assembly connected to the two connecting rods is arranged inside the mounting plate. At the top of one end of each of the two connecting rods, a positioning assembly connected to the adjacent clamping block is respectively arranged. Support legs are provided at the bottom of the mounting plate.

[0007] Preferably, the clamping assembly includes a motor disposed on one side of the mounting plate, and the bottom of the motor is fixedly installed on the adjacent outer sidewall of the mounting plate through a bracket. The output end of the motor is drivingly connected to a bidirectional lead screw. The end of the bidirectional lead screw away from the motor is rotatably connected to the adjacent inner sidewall of the mounting plate. Both ends of the outer portion of the bidirectional lead screw are sleeved with screw sleeves, and one side of the outer rings of the two screw sleeves is fixedly connected to the sidewall of the adjacent end of the adjacent connecting rod.

[0008] Preferably, the positioning assembly includes a jack formed at the top of one end of the connecting rod. A slot is formed at the top of the clamping block. Slide plates are fixedly connected to both sides of the clamping block. Sliding grooves adapted to the slide plates are formed on both inner sidewalls of the connecting rod at one end and on both sides of the slot.

[0009] Preferably, the positioning assembly further includes a connecting plate disposed at the top of one end of the connecting rod. The connecting plate is in an inverted U shape, and both bottom ends of the connecting plate are fixedly connected to the top of the connecting rod. A pull rod is disposed inside the connecting plate. The bottom end of the pull rod is inserted into the slot through the jack. The top end of the pull rod penetrates through the top of the connecting plate and is fixedly connected to a pull block. A spring is sleeved on the outer portion of the pull rod. Both ends of the spring are fixedly connected to the bottom of the pull block and the top of the connecting plate respectively.

[0010] Preferably, a circular groove is formed on one side of the bottom of the pull block, a limiting groove is formed on one side of the top of the connecting plate, a limiting plate adapted to the limiting groove is disposed on the top of the connecting plate, and a plug rod adapted to the circular groove is fixedly connected to the top of the limiting plate.

[0011] Preferably, one side of the outer rings of the two screw sleeves away from the connecting rod is fixedly connected with a limiting block, and a connecting groove adapted to the limiting block is formed on one inner sidewall of the mounting plate.

[0012] The utility model has at least the following beneficial effects:

[0013] Hold the pull block and pull the pull rod upward to separate the bottom end thereof from the slot to release the positioning of the clamping block, which is convenient for disassembling the clamping plate and the connecting rod and can flexibly replace other types or different sizes of clamping plates. During installation, after the clamping block is engaged with the slot, release the pull block, and the elastic recovery of the spring pulls the pull block to insert the bottom end of the pull rod into the slot to position the clamping block, thereby improving the flexibility of clamping and adapting to position flanges of different sizes, reducing the operation burden and use cost of personnel, and enhancing its practicability.

[0014] The utility model also has the following beneficial effects:

[0015] The starting motor drives the bidirectional lead screw to make the two nuts approach each other, causing the connecting rod and the clamping block to make the two clamping plates clamp and position the outer ends of the flange. To a certain extent, it can adapt to flanges of different diameters. When pulling the pull block upward and moving the limit plate to make the insertion rod directly below the circular groove, releasing the pull block makes the circular groove abut against the top of the insertion rod to position the pull block. There is no need for personnel to keep pulling the pull block by hand, so that they can free their hands to operate the loading and unloading of the clamping block and the clamping plate, bringing flexibility and convenience to the personnel's operation of clamping and positioning.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] In order to make the objectives, technical solutions and advantages of the present invention clearer, the following further describes the present invention in detail with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

[0024] Refer to Figures 1-5, A positioning mechanism for improving clamping flexibility and flange production, including a mounting plate 1. Two clamping plates 7 are symmetrically arranged inside the mounting plate 1. On the side of each of the two clamping plates 7 away from each other, a clamping block 8 is fixedly connected. Two connecting rods 5 are symmetrically arranged inside the mounting plate 1, and the connecting rods 5 are L-shaped. At one end of each of the two connecting rods 5, a clamping groove adapted to the clamping block 8 is provided. A clamping component connected to the two connecting rods 5 is arranged inside the mounting plate 1. At the top of one end of each of the two connecting rods 5, a positioning component connected to the adjacent clamping block 8 is respectively provided. Support legs are provided at the bottom of the mounting plate 1. Specifically, by operating the positioning component, it is convenient to disassemble the clamping plate 7 and the connecting rod 5, and other types or different sizes of clamping plates 7 can be flexibly replaced, thereby improving the flexibility of the clamping tool to adapt to different sizes of flanges, and the flange can be positioned. By starting the clamping component, the two clamping plates 7 move to clamp and position the outer sides of the flange, and within a certain extent, it can adapt to flanges with different diameter sizes, reducing the operation burden and use cost of personnel and enhancing its practicability.

[0025] Further, the clamping component includes a motor 2 arranged on one side of the mounting plate 1, and the bottom of the motor 2 is fixedly installed on the adjacent outer side wall of the mounting plate 1 through a bracket. The output end of the motor 2 is drivingly connected to a bidirectional lead screw 3. The end of the bidirectional lead screw 3 away from the motor 2 is rotatably connected to the adjacent inner side wall of the mounting plate 1. Both ends of the outer part of the bidirectional lead screw 3 are sleeved with screw sleeves 4. On one side of the outer ring of each of the two screw sleeves 4, it is fixedly connected to the side wall of the adjacent end of the adjacent connecting rod 5. Specifically, through the setting of the screw sleeve 4, by starting the motor 2 to drive the bidirectional lead screw 3 to rotate, the bidirectional lead screw 3 immediately causes the two screw sleeves 4 to generate a lateral displacement of approaching each other. The screw sleeve 4 then drives the connecting rod 5 and the clamping block 8 to move the clamping plate 7, thereby clamping and positioning the outer ends of the flange, and within a certain extent, it can adapt to flanges with different diameter sizes.

[0026] Further, the positioning component includes a jack formed at the top of one end of the connecting rod 5, a slot is formed at the top of the clamping block 8, and sliding plates 9 are fixedly connected to both sides of the clamping block 8. At both inner walls of the slot on both sides of one end of the connecting rod 5, sliding grooves adapted to the sliding plates 9 are provided. Specifically, through the setting of the sliding plates 9 and the sliding grooves, personnel can align the sliding plates 9 on both sides of the clamping block 8 with the two sliding grooves in the slot at one end of the connecting rod 5 and slide them in, so that the clamping block 8 is clamped and adapted to the slot, which is not only convenient for personnel to clamp but also can provide good limitation for the clamping block 8.

[0027] Furthermore, the positioning component further includes a connecting plate 10 provided at the top end of one end of the connecting rod 5. The connecting plate 10 is in an inverted U shape, and both bottom ends of the connecting plate 10 are fixedly connected to the top of the connecting rod 5. A pull rod 11 is provided inside the connecting plate 10. The bottom end of the pull rod 11 is inserted into the slot through the jack. The top end of the pull rod 11 penetrates through the top of the connecting plate 10 and is fixedly connected with a pull block 13. A spring 12 is sleeved outside the pull rod 11. Both ends of the spring 12 are fixedly connected to the bottom of the pull block 13 and the top of the connecting plate 10 respectively. Specifically, through the arrangement of the spring 12, a person can pull the pull rod 11 upward by holding the pull block 13. At this time, the pull block 13 also stretches the spring 12. When the pull rod 11 moves, its bottom end is separated from the slot inside to release the positioning of the clamping block 8, facilitating the disassembly of the clamping plate 7 and the connecting rod 5, and facilitating the person to flexibly replace other types or different sizes of clamping plates 7. During installation, after the clamping block 8 is engaged with the clamping slot, the pull block 13 is released, so that the spring 12 loses the extrusion force and is elastically restored to pull the pull block 13 to drive the pull rod 11 to return to its position, so that the bottom end of the pull rod 11 is inserted into the slot, thereby positioning the clamping block 8 to fix the clamping plate 7, thus improving the flexibility of the clamping tool to adapt to different sizes of flanges, and being able to position the flange, reducing the operation burden and use cost of the person, and enhancing its practicability.

[0028] Furthermore, a circular groove is formed on one side of the bottom of the pull block 13, and a limiting groove is formed on one side of the top of the connecting plate 10. A limiting plate adapted to the limiting groove is provided on the top of the connecting plate 10, and a plug rod 14 adapted to the circular groove is fixedly connected to the top of the limiting plate. Specifically, through the arrangement of the pull block 13, when a person pulls the pull block 13 upward, the limiting plate in the limiting groove can be moved to make the plug rod 14 move to directly below the circular groove, and then the pull block 13 is released to make the circular groove abut against the top end of the plug rod 14, so that the pull block 13 is positioned, and the person does not need to keep pulling the pull block 13 by hand, thus freeing up the hand to operate the loading and unloading of the clamping block 8 and the clamping plate 7, bringing flexibility and convenience to the person's operation of clamping and positioning.

[0029] Furthermore, limiting blocks 6 are fixedly connected to the outer sides of the two screw sleeves 4 away from the connecting rod 5. A connecting groove adapted to the limiting block 6 is formed on one inner wall of the mounting plate 1. Specifically, through the arrangement of the limiting block 6, the limiting block 6 can limit the screw sleeve 4 through the connecting groove to prevent the screw sleeve 4 from rotating together with the bidirectional lead screw 3.

[0030] In summary:

[0031] By holding the pulling block 13 and pulling the pull rod 11 upward to move, at this time, the pulling block 13 also stretches the spring 12. When the pull rod 11 moves, its bottom end is separated from the slot to release the positioning of the clamping block 8, facilitating the disassembly of the clamping plate 7 and the connecting rod 5, which is convenient for personnel to flexibly replace other types or different sizes of clamping plates 7. During installation, after the clamping block 8 is engaged with the card slot, the pulling block 13 is released, so that the spring 12 loses the extrusion force and is elastically restored to drive the pulling block 13 to drive the pull rod 11 to return to its position, making the bottom end of the pull rod 11 inserted into the slot, thereby positioning the clamping block 8 to fix the clamping plate 7, so as to improve the flexibility of the clamping tool to adapt to different sizes of flanges, and be able to position the flange, reducing the operation burden and use cost of personnel and enhancing its practicability.

[0032] By starting the motor 2 to drive the bidirectional lead screw 3 to rotate, the bidirectional lead screw 3 immediately causes two screw sleeves 4 to generate a lateral displacement of approaching each other. The screw sleeve 4 then drives the connecting rod 5 and the clamping block 8 to move the clamping plate 7, thereby clamping and positioning the outer ends of the flange, and adapting to flanges with different diameter sizes to a certain extent. When the personnel pull the pulling block 13 upward, they can move the limiting plate in the moving limiting groove to make the inserting rod 14 move to directly below the circular groove, and then release the pulling block 13 to make the circular groove abut against the top end of the inserting rod 14, thereby positioning the pulling block 13, so that the personnel can free their hands to operate the loading and unloading of the clamping block 8 and the clamping plate 7 without having to keep pulling the pulling block 13 by hand, bringing flexibility and convenience to the personnel's operation of clamping and positioning.
