A positioning device for fastener production and processing

Abstract

The invention discloses a positioning device for fastener production and processing, and relates to the field of positioning technology. The positioning device for fastener production and processing comprises a polishing machine, wherein a motor is arranged on the inner wall of the polishing machine, and an inner wall clamping and positioning mechanism is arranged on one side of the motor; by arranging the inner wall clamping and positioning mechanism, the installation is relatively stable and cannot be directly pulled out. When it is necessary to directly pull it out, only one hand is needed to grasp three push blocks and press them inward, so that the three push blocks can drive the moving rod to move through the connecting plate, thereby loosening the pressed pressing plate. At this time, when the internal thread sleeve is pulled outward, the thread groove in the internal thread sleeve can squeeze the inclined pressing plate side surface, and squeeze the pushing pressing plate, the round rod, and the sliding rod until the spring B with smaller elastic force at this time is deformed, so that the thread groove in the internal thread sleeve can be separated and pulled out from the squeezing of the pressing plate, thereby completing the function of quickly positioning and disassembling the internal thread sleeve.

[0017] The present invention provides a positioning device for fastener production and processing. It has the following beneficial effects:

[0018] 1. The present invention provides an inner wall clamping and positioning mechanism, and several flat pressure plates can be inserted into the thread groove, so that a certain self-locking effect is generated between the thread groove and the pressure plate, making it impossible to directly pull out, thereby completing the automatic tightening effect of the internal thread sleeve, and the installation is convenient and fast, and the installation is relatively stable. If it cannot be directly pulled out, when it needs to be directly pulled out, only one hand is needed to grasp the three push blocks and press them inward, so that the three push blocks can drive the moving rods to move through the connecting plate, thereby loosening the pressed pressure plate. At this time, when the internal thread sleeve is pulled outward, the thread groove in the internal thread sleeve can squeeze the inclined side of the pressure plate, and squeeze the push pressure plate, the round rod, and the sliding rod until the spring B with smaller elastic force at this time is deformed, so that the thread groove in the internal thread sleeve can be separated from the pressure of the pressure plate and pulled out, thereby completing the function of quickly positioning and disassembling the internal thread sleeve.

[0019] 2. The present invention provides an auxiliary mechanism so that the internal thread sleeve cannot slip on the pressure plate due to relative rotation with the pressure plate, and the problem of the internal thread sleeve sliding loosely to the left and right is avoided, thereby achieving a stable clamping and fixing effect on the internal thread sleeve from the inside to the outside in a quick and convenient manner, and the clamping of the pressure plate deep into the thread groove avoids the problem of thread deformation caused by conventional clamping and squeezing of the protruding position of the thread groove. The deformation problem caused by clamping in the thread groove can be avoided by the pressure plate deeply squeezing the inside of the thread groove.

[0020] 3. The present invention sets an auxiliary mechanism, which will drive the sliding rod, the round rod and the pressure plate to rotate synchronously when the fixed sleeve rotates, and the sliding rod, the round rod and the pressure plate will be subjected to the centrifugal force of rotation, thereby generating an outward squeezing force on the inner wall of the internal threaded sleeve, so that the internal threaded sleeve is squeezed tighter, and the clamping force is limited when polishing is not rotating, which is convenient for loading and unloading operations. In the polishing and grinding process, the clamping and fixing force can be automatically increased to achieve stable clamping in the polishing state and quick operation in the non-polishing state.

[0021] 4. The present invention provides an auxiliary mechanism. When different scale blocks on the opening and closing plate are pressed against the internal threaded sleeve fastener, the lifting angle of the opening and closing plate can be judged by observing which scale block on the opening and closing plate is in close contact with the right side of the inner wall of the internal threaded sleeve. Then, the staff can judge the inner diameter of the internal threaded sleeve under the same length of fasteners, thereby facilitating the implementation of a targeted grinding and polishing plan for its inner diameter and improving the working efficiency of grinding and polishing.

DETAILED DESCRIPTION

[0036] Example 1: Please refer to Figure 1-4 , the present invention provides a technical solution: a positioning device for fastener production and processing, comprising a polishing machine 1, a motor 2 is arranged on the inner wall of the polishing machine 1, and an inner wall clamping and positioning mechanism 3 is arranged on one side of the motor 2;

[0037] The inner wall clamping and positioning mechanism 3 comprises:

[0038] Fixed shaft A301, one end of fixed shaft A301 is fixedly connected to the output end of motor 2, one end of fixed shaft A301 is fixedly connected to a fixed sleeve 303, the fixed sleeve 303 is a sleeve-shaped structure, the outer wall of the fixed sleeve 303 is fixedly connected to a connecting disk 302, and the fixed shaft A301 is used to support the motor 2 and the fixed sleeve 303.

[0039] Push block 305, the outer wall of push block 305 is slidably connected to the inner wall of fixed sleeve 303, both sides of push block 305 are inclined surfaces, the outer wall of push block 305 is fixedly connected with spring A306, one end of spring A306 is fixedly connected with connecting sleeve 307, the inner wall of connecting sleeve 307 is fixedly connected with fixed shaft B316, one end of fixed shaft B316 is fixedly connected to the left side of the inner wall of columnar groove 304, the inclined surface of push block 305 is used to slide toward the inner wall of columnar groove 304 when pushed by fastener.

[0040] When in use, the internal threaded sleeve to be positioned is pushed onto the fixed sleeve 303, the inner wall of the internal threaded sleeve contacts the surface of the push block 305, and the push block 305 is pushed by the inclined surface of the outer wall of the push block 305, and the pushed push block 305 squeezes the spring A306 to slide into the cylindrical groove 304 on the inner wall of the fixed sleeve 303, so that the three push blocks 305 are squeezed into the cylindrical groove 304;

[0041] Example 2: Please refer to Figure 1-9 Based on the first embodiment, the present invention provides a technical solution:

[0042] A connecting plate 308 is fixedly connected to the outer wall of the push block 305 , a moving rod 310 is fixedly connected to one side of the connecting plate 308 , and a circular plate 311 is fixedly connected to one end of the moving rod 310 .

[0043] A spring B312 is fixedly connected to one side of the circular plate 311 , a sliding rod 313 is fixedly connected to one end of the spring B312 , and a round rod 314 is fixedly connected to one end of the sliding rod 313 .

[0044] One end of the round rod 314 is fixedly connected with a pressing plate 315 . The pressing plate 315 is an arc-shaped plate-like structure, and the cross section of the pressing plate 315 is a triangular shape.

[0045] A support spring 317 is fixedly connected to the outer wall of the fixed shaft B316 , and one end of the support spring 317 is fixedly connected to the circular plate 311 . The support spring 317 plays a role in supporting the circular plate 311 .

[0046] When the push block 305 slides, the moving rod 310 is driven to move through the connecting plate 308, and the moving rod 310 drives the circular plate 311 and the spring B312 to move, and the spring B312 moves with the sliding rod 313, and the pressure plate 315 extends farther from the fixed sleeve 303 than the push block 305. Because when the push block 305 is pressed by the internal thread sleeve fastener, the sliding rod 313, the round rod 314, and the pressure plate 315 are driven to move synchronously, so when the inner wall of the internal thread sleeve is against the push block 305, the tip of the pressure plate 315 is slightly longer and the position is a little longer than the inner wall of the thread sleeve. When the internal thread sleeve continues to be pushed in, it contacts one side of the pressure plate 315, and applies a thrust to the fixed sleeve 303 through the inclined surface on one side of the pressure plate 315. The pressure plate 315 is deformed by squeezing the spring B312 through the round rod 314 and the sliding rod 313. As the internal thread sleeve continues to be pushed, the threads in the internal thread sleeve continuously push the pressure plate 315 to the sliding rod 313 to squeeze the spring B312 to move, so that the threads in the internal thread sleeve continuously move the pressure plate 315 back and forth, and the internal thread sleeve continuously penetrates into the connecting disk 302 and abuts against the connecting disk 302.

[0047] After that, the internal thread sleeve will be separated from the push block 305, so that the push block 305 is pushed back to its original position by the elastic force of the spring A306, and the circular plate 311 and the spring B312 are moved by the connecting plate 308 and the moving rod 310, and the pressing plate 315, the round rod 314, and the sliding rod 313 are pressed against the inner wall of the internal thread sleeve, so the moving rod 310 drives the circular plate 311 to move and squeeze the spring B312, so that the elastic force of the spring B312 increases and pushes the sliding rod 313 until the pressing plate 315 and the threads of the inner wall of the internal thread sleeve are pressed against each other. If the inner wall of the internal thread sleeve is separated from the push block 305, it only needs to rotate the internal thread sleeve so that the thread groove of the inner wall slides and rotates on the flat pressing plate 315 to slide to the connecting disk 302;

[0048] The flat pressing plate 315 is inserted into the thread groove of the inner wall of the internal thread sleeve, so that the internal thread sleeve can be quickly clamped and disengaged, and several flat pressing plates 315 can be inserted into the thread groove, so that a certain self-locking effect is generated between the thread groove and the pressing plate 315, so that it cannot be directly pulled out, and the internal thread sleeve is automatically tightened. The installation is convenient and fast, and the installation is relatively stable. If it cannot be directly pulled out, when it needs to be directly pulled out, only one hand needs to grasp the three push blocks 305 and press them inwards, that is, The three push blocks 305 can drive the moving rod 310 to move through the connecting plate 308, thereby loosening the pressed plate 315. At this time, when the internal threaded sleeve is pulled outward, the thread groove in the internal threaded sleeve can squeeze the side of the inclined pressing plate 315, and the pressing plate 315, the round rod 314, and the sliding rod 313 are squeezed to the point that the spring B312 with a smaller elastic force at this time is deformed, so that the thread groove in the internal threaded sleeve can be pulled out from under the squeezing of the pressing plate 315, thereby completing the function of quickly positioning and disassembling the internal threaded sleeve;

[0049] After one end of the internal thread sleeve is against the connecting plate 302, the polishing machine 1 controls the motor 2 to rotate to drive the fixed shaft A301, the connecting plate 302 and the fixed sleeve 303 to rotate synchronously, thereby driving the internal thread sleeve to rotate synchronously through the rotation of the pressing plate 315, and then the external polishing brush is used to complete the polishing and grinding of the internal thread sleeve fastener;

[0050] Example 3: Please refer to Figure 1-13 On the basis of the first and second embodiments, the present invention provides a technical solution: the outer wall of the fixed sleeve 303 is rotatably connected to the rotating shaft 401, and the outer wall of the rotating shaft 401 is fixedly connected to the opening and closing plate 402.

[0051] A scale block 403 is fixedly connected to the outer wall of the opening and closing plate 402 , a groove 405 is opened at one end of the opening and closing plate 402 , and a counterweight block 404 is fixedly connected to one end of the opening and closing plate 402 .

[0052] An elastic rope 406 is fixedly connected to the inner wall of the groove 405 , and one end of the elastic rope 406 is fixedly connected to the outer wall of the fixing sleeve 303 . The scale block 403 is made of rubber.

[0053] When the fixed sleeve 303 rotates, the counterweight 404 has a large mass and is subject to a large inertia. Therefore, under the action of the centrifugal force of the rotation, the counterweight 404 will rotate with the opening and closing plate 402 and the rotating shaft 401 and open and close outward. When the opening and closing plate 402 opens and closes outward, it will press against one side of the internal threaded sleeve, thereby pressing the internal threaded sleeve, increasing the contact and extrusion force between the internal threaded sleeve and the connecting plate 302, maintaining the further stability of the internal threaded sleeve, and preventing the internal threaded sleeve from sliding left and right on the fixed sleeve 303 by pressing the internal threaded sleeve. The threads on the inner wall of the internal threaded sleeve are embedded in the pressing plate 315, so the internal threaded sleeve cannot slide left and right on the pressing plate 315, nor can it produce a relative sliding asynchronous rotation with the rotation of the fixed sleeve 303, because the internal threaded sleeve If the pressing plate 315 is to rotate and slide due to the small friction force, the internal threaded sleeve will produce a lateral displacement under the action of the pressing plate 315 due to the threads on the inner wall, but the displacement to the left is resisted by the connecting plate 302, and the displacement to the right is resisted by the lifting of the opening and closing plate 402, so that the internal threaded sleeve cannot produce a relative rotation slip with the pressing plate 315 on the pressing plate 315, and the problem of the internal threaded sleeve sliding left and right is avoided. The internal threaded sleeve is clamped and fixed from the inside to the outside quickly and conveniently, and the clamping of the pressing plate 315 deep into the thread groove avoids the problem of thread deformation caused by conventional clamping and squeezing of the protruding position of the thread groove, and the deformation problem caused by clamping in the thread groove can be avoided by the pressing plate 315 deep squeezing the inside of the thread groove.

[0054] When the fixed sleeve 303 rotates, the sliding rod 313, the round rod 314, and the pressing plate 315 will be driven to rotate synchronously, and the sliding rod 313, the round rod 314, and the pressing plate 315 will be subjected to the centrifugal force of the rotation, thereby generating an outward squeezing force on the inner wall of the internal thread sleeve, so that the internal thread sleeve is squeezed tighter, so that when the polishing is not rotating, the clamping force is limited, which is convenient for loading and unloading operations, and in the polishing and grinding process, the clamping and fixing force can be automatically increased, so as to achieve stable clamping in the polishing state and quick operation in the non-polishing state;

[0055] When the counterweight block 404 rotates with inertia to hinge the opening and closing plate 402 and the rotating shaft 401 to open and close, and presses one side of the internal threaded sleeve, the scale block 403 on the outer wall of the opening and closing plate 402 is stuck at the rightmost part of the inner wall of the internal threaded sleeve, and the friction force of the rubber of the scale block 403 is used to reduce the mutual sliding caused by insufficient friction. The opening and closing plate 402 overcomes the elastic force of the elastic rope 406 and opens and closes and is lifted. When different scale blocks 403 on the opening and closing plate 402 are pressed against the internal threaded sleeve fastener, it is possible to determine the lifting angle of the opening and closing plate 402 by observing which scale block 403 on the opening and closing plate 402 is in close contact with the right side of the inner wall of the internal threaded sleeve. Then, the staff can determine the inner diameter of the internal threaded sleeve under the same length of fasteners, thereby facilitating the targeted grinding and polishing of its inner diameter and improving the grinding and polishing work efficiency.

[0056] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
