Description

Technical Field

[0001] This utility model relates to the field of clamping technology, and in particular to a clamping and fixing device for the production of precision parts. Background Technology

[0002] Parts refer to individual, indivisible components in machinery. They are the basic building blocks of machines and the basic units in the mechanical manufacturing process. Their manufacturing process generally does not require assembly steps. Examples include bushings, bearings, nuts, crankshafts, blades, gears, cams, connecting rods, and connecting rod heads. High-precision parts require high accuracy in data processing. In the production of high-precision parts, clamping and fixing devices are needed to clamp and fix the high-precision parts.

[0003] Existing clamping and fixing devices typically use threaded rods for adjustment to change the position of the clamping arms and thus clamp and fix precision parts. However, during actual use, when precision parts are being processed, debris tends to stick to the outer surface of the threaded rod, which can cause jamming between the threaded rod and the clamping arms during adjustment. To address this, we propose a clamping and fixing device for precision parts manufacturing. Utility Model Content

[0040] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0041] Example:

[0042] like Figures 1-3 As shown, a clamping and fixing device for precision parts manufacturing includes:

[0043] Mounting frame 1, with a mounting groove at its top;

[0044] The connecting clamping mechanism 2 is fixedly welded to the mounting groove on the top of the mounting frame 1;

[0045] The second fixed through groove 3 is symmetrically opened on the top of the mounting frame 1;

[0046] Fixed guide and limiting grooves 4 are symmetrically opened on the top of the mounting frame 1;

[0047] A fixing slot 5 is provided inside the mounting frame 1;

[0048] Fixed limiting sleeve 6 is symmetrically arranged on the front surface of mounting frame 1;

[0049] The active collection mechanism 7 is movably inserted into the inside of the fixed slot 5 and connected to the fixed limiting sleeve 6;

[0050] Fixed guide mechanism 8 is symmetrically arranged at the bottom of mounting frame 1;

[0051] The connecting base plate 9 is fixedly mounted at the bottom end of the fixed guide mechanism 8;

[0052] The lifting and adjusting mechanism 10 is fixedly installed at the top center of the connecting base plate 9, and its output end is fixedly connected to the bottom end of the mounting frame 1.

[0053] The working principle of the above technical solution is as follows:

[0054] During use, the connecting clamping mechanism 2 can clamp and fix the workpiece. At the same time, when the workpiece is being processed, the connecting clamping mechanism 2 can provide effective protection for its internal components and guide the debris. The movable collection mechanism 7 can collect the debris. According to the size of the workpiece, the overall height can be raised through the connecting base plate 9 and the fixed guide mechanism 8 to facilitate the processing of the workpiece and make the operation convenient.

[0055] In another embodiment, such as Figure 2 As shown, the connecting clamping mechanism 2 includes a first connecting base frame 21. A fixed inner groove 22 is provided inside the first connecting base frame 21. A first bidirectional threaded rod 23 is movably connected inside the first connecting base frame 21. Both ends of the first bidirectional threaded rod 23 are fixedly connected to connecting end plates 24. A first rotating end block 28 is fixedly connected to one of the connecting end plates 24 away from the first bidirectional threaded rod 23. A movable base block 25 is movably sleeved on the outer surface of the first bidirectional threaded rod 23. A connecting clamping arm 26 is fixedly connected to the top of the movable base block 25. A first fixed through groove 27 is provided inside both the first connecting base frame 21 and the movable base block 25. A movable baffle plate 29 is movably inserted into the inner side of the first fixed through groove 27. A connecting end block 210 is fixedly connected to one end of the movable baffle plate 29. A fastening bolt 212 is connected between the connecting end block 210 and the first connecting base frame 21. Threaded mounting holes 211 are symmetrically provided on the side of the first connecting base frame 21 near the first rotating end block 28.

[0056] The movable baffle 29 provides stable protection for the first bidirectional threaded rod 23, preventing debris from sticking to the outer surface of the first bidirectional threaded rod 23 and causing jamming between the movable base block 25 and the first bidirectional threaded rod 23. It also rotates the first rotating end block 28, causing the connecting end plate 24 and the first bidirectional threaded rod 23 to rotate, allowing the movable base block 25 to move to the outer surface of the first bidirectional threaded rod 23. This allows the connecting clamping arm 26 to clamp and fix the workpiece, making the operation convenient and quick.

[0057] In another embodiment, such as Figure 2 As shown, a movable shielding guide plate 213 is fixedly connected to one side of the connecting clamping arms 26 that are far apart from each other. A guide block 214 is fixedly connected to the bottom end of each movable shielding guide plate 213. The outer surface of the guide block 214 slides and fits against the inner side of the fixed guide limiting groove 4.

[0058] The movable shielding guide plate 213 facilitates the guidance of debris, allowing it to move stably through the second fixed through slot 3 towards the inner side of the movable collection mechanism 7 for collection. Simultaneously, when the movable shielding guide plate 213 moves, it also allows the guide block 214 to move stably within the 4° area, making operation convenient.

[0059] In another embodiment, such as Figure 2 As shown, the active collection mechanism 7 includes an active collection box 71. A connecting end plate 72 is fixedly connected to one side of the active collection box 71. A connecting handle 73 is fixedly connected to the middle of the side of the connecting end plate 72 away from the active collection box 71. A connecting T-shaped positioning block 74 is symmetrically provided on the side of the connecting end plate 72 away from the active collection box 71. An active deflection limiting arm 75 is movably sleeved on the outer surface of the connecting T-shaped positioning block 74. The outer surface of the bottom end of the active deflection limiting arm 75 is in contact with the inner side of the fixed limiting sleeve 6.

[0060] This facilitates the deflection of the movable deflection limit arm 75, allowing its bottom end to be pulled out from the inside of the fixed limit sleeve 6 and no longer connected to it. Then, the connecting handle 73 is pulled, causing the connecting end plate 72 and the movable collection box 71 to move and be pulled out, thereby cleaning the debris collected inside the movable collection box 71. This makes the operation convenient.

[0061] In another embodiment, such as Figure 3 As shown, the fixed guide mechanism 8 includes a connecting base block 81, a connecting sleeve block 82 is movably sleeved on the outer surface of the connecting base block 81, a fixed guide groove 83 is opened on the surface of the connecting sleeve block 82, a connecting bolt 84 is movably inserted into the interior of the connecting base block 81, and a fastening nut 85 is movably connected to the outer surface of the end of the connecting bolt 84.

[0062] When the height of the frame 1 is moved upward, it can drive the connecting base block 81 to move, which in turn drives the connecting bolt 84 and the fastening nut 85 to move. This allows the connecting bolt 84 to move inside the fixed guide groove 83, while the connecting base block 81 can move inside the connecting sleeve block 82, thus providing guidance and making operation convenient.

[0063] In another embodiment, such as Figure 3 As shown, the outer side of the end surface of the connecting bolt 84 slides and fits against the inner side of the fixed guide groove 83.

[0064] This allows the connecting bolt 84 to move stably inside the fixed guide groove 83, making operation convenient.

[0065] In another embodiment, such as Figure 3 As shown, the lifting adjustment mechanism 10 includes a second connecting base frame 101. A second bidirectional threaded rod 102 is movably connected inside the second connecting base frame 101. Each end of the second bidirectional threaded rod 102 is fixedly connected to a limiting end block 103. A fixed connecting rod 104 is fixedly connected to the side of one of the limiting end blocks 103 away from the second bidirectional threaded rod 102. A second rotating end block 105 is fixedly connected to the end of the fixed connecting rod 104 away from the limiting end block 103. A movable mounting block 106 is movably sleeved on the outer surface of the second bidirectional threaded rod 102. A first connecting block 107 is fixedly connected to the top of the movable mounting block 106. A deflection support arm 108 is movably connected to the inner side of the first connecting block 107 through a connecting shaft. A second connecting block 109 is movably connected to the other end of the deflection support arm 108 through a connecting shaft. The top end of the second connecting block 109 is fixedly connected to the bottom end of the mounting frame 1.

[0066] The second rotating end block 105 is easily rotated, which drives the fixed connecting rod 104, the limiting end block 103, and the second bidirectional threaded rod 102 to rotate. This allows the movable mounting block 106 to move stably on the outer surface of the second bidirectional threaded rod 102, thereby driving the first connecting block 107 to move. This allows the deflection support arm 108 to deflect, pushing the second bidirectional threaded rod 102 upward, thus enabling the height of the mounting frame 1 to be adjusted. This makes the operation convenient.

[0067] The working principle of this utility model is as follows: During use, the part is placed on top of the first connecting base frame 21. Then, the first rotating end block 28 is rotated, which drives the connecting end plate 24 and the first bidirectional threaded rod 23 to rotate. This allows the moving base block 25 to move on the outer side of the surface of the first bidirectional threaded rod 23, thereby driving the connecting clamping arm 26, the movable shielding guide plate 213, and the guide base block 214 to move. This allows the guide base block 214 to move inside the fixed guide limiting groove 4, thereby clamping and fixing the workpiece. Then, the second rotating end block 1... 05 rotates, causing the fixed connecting rod 104, the limiting end block 103, and the second bidirectional threaded rod 102 to rotate, so that the movable mounting block 106 can move stably on the outer surface of the second bidirectional threaded rod 102, causing the first connecting block 107 to move, so that the deflection support arm 108 can deflect, pushing the second bidirectional threaded rod 102 upward, thereby adjusting the height of the mounting frame 1. When the mounting frame 1 moves, it causes the connecting bottom block 81 to move, causing the connecting bolt 84 and the fastening nut 85 to move. The movement allows the connecting bolt 84 to move inside the fixed guide groove 83, while the connecting base block 81 can move inside the connecting sleeve block 82, thus providing guiding and limiting treatment. Finally, during the machining of the part, the movable baffle 29 can continuously protect the first bidirectional threaded rod 23, preventing debris from adhering to the outer surface of the first bidirectional threaded rod 23 and causing jamming between the first bidirectional threaded rod 23 and the movable base block 25. At the same time, the movable baffle guide plate 213 can guide the debris, allowing it to enter through the second fixed groove 3. The debris is collected inside the movable collection box 71. When it is necessary to clean the debris collected inside the movable collection box 71, the movable deflection limit arm 75 is deflected so that the bottom end of the movable deflection limit arm 75 can be pulled out from the inside of the fixed limit sleeve 6 and is no longer connected to the fixed limit sleeve 6. Then, the connecting handle 73 is pulled to move the connecting end plate 72 and the movable collection box 71, thereby pulling out the movable collection box 71 and cleaning the debris collected inside the movable collection box 71. The overall structure is simple and the operation is convenient and quick.

[0068] The above embodiments merely illustrate specific implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
