[0002] A fixture is a device used to fix the object to be processed in the mechanical manufacturing process so that it occupies the correct position for construction or inspection. It is also called a clamp. In a broad sense, any device used to quickly, conveniently and safely install the workpiece in any process can be called a fixture. Commonly used fixtures require workers to use tools to install the fixture when used to fix and clamp mechanical workpieces. The installation of the fixture is cumbersome and the installation efficiency is low.

[0033] The utility model is described in detail below with reference to the accompanying drawings.

[0034] like Figure 1-4As shown, a fixing mechanism that is convenient for disassembly and assembly includes a tool 1 and an installation component 3 for installing the tool 1, the installation component 3 includes a connecting plate 21 and a locking pressure plate 22 arranged on the connecting plate 21, and the connecting plate 21 can move longitudinally; the tool 1 includes a connecting block 11, and the connecting block 11 can be inserted into the locking pressure plate 22; a tension connector 2 is provided between the locking pressure plate 22 and the connecting plate 21, which can loosely install the connecting block 11 on the locking pressure plate 22; during installation, the tool 1 is connected to the locking pressure plate 22 of the connecting plate 21 through the connecting block 11, and the tension connector 2 of the locking pressure plate 22 can adjust the tightness of the connection between the locking pressure plate 22 and the connecting block 11 to achieve installation; when loosening, the locking pressure plate 22 is moved away from the connecting block 11 through the tension connector 2, so that the connecting block 11 can be pulled out from the locking pressure plate 22, and the disassembly is quickly completed without removing all the screws. The operation is simple, the process is concise, and the efficiency is high.

[0035] Preferably, the tooling 1 also includes a connecting rod 13 inserted into the connecting block 11, and a mating block 12 is respectively formed on both sides of the connecting block 11. The elastic connecting piece 2 includes a mating groove 23 formed at the bottom of the locking pressure plate 22 for the mating block 12 to slide and embed. The mating blocks 12 formed on both sides of the connecting block 11 are slidably matched with the mating groove 23 of the locking pressure plate 22, and can be slidably inserted into the bottom of the locking pressure plate 22 to be connected to the connecting plate 21.

[0036] Furthermore, the locking pressure plate 22 is provided with a top adjustment hole 24, and the connecting plate 21 is formed with a bottom adjustment hole 25 coaxially aligned with the top adjustment hole 24, and an adjustment rod 26 is installed between the top adjustment hole 24 and the bottom adjustment hole 25; after the connecting block 11 and the engaging block 12 are slidably inserted into the engaging groove 23 of the locking pressure plate 22, the distance between the locking pressure plate 22 and the connecting plate 21 can be adjusted by rotating the adjusting rod 26, so that the connecting block 11 can be fixedly engaged on the connecting plate 21, and the disassembly of the connecting block 11 can be realized by adjusting the tightness, and the tooling 1 can be quickly disassembled without removing all the screws, which is simple to operate, concise and efficient.

[0037] The connecting rod 13 of the tooling 1 is equipped with a pair of spaced-apart pressing blocks 14, a silicone insert 15 is installed at the bottom of the pressing block 14, an elastic connecting sleeve 16 is slidably installed on the connecting rod 13, and the pressing block 14 is installed on the elastic connecting sleeve 16. The pressing block 14 presses down the product or workpiece to position it. When pressing down, the silicone insert 15 elastically contacts the product, which can reduce the wear on the product and protect the product. In addition, the position of the pressing block 14 can also be adjusted by the elastic connecting sleeve 16.

[0038] The mounting assembly 3 also includes a longitudinal driving member that drives the connecting plate 21 to move longitudinally, and the longitudinal driving member includes a longitudinal driving rod 31 that can move up and down, a wedge block 32 is installed on the top of the longitudinal driving rod 31, and a connecting seat 33 is installed at the bottom of the connecting plate 21, and the connecting seat 33 is formed with a wedge-shaped groove 34 connected to the wedge block 32. The longitudinal driving rod 31 is connected to the connecting seat 33 at the bottom of the connecting plate 21 through the wedge block 32. The longitudinal driving rod 31 drives the connecting plate 21 to move up and down by the lifting and lowering movement, so that the tooling 1 can move up and down to press and position the product, and the design of the wedge block 32 and the wedge groove 34 can separate and disassemble the longitudinal driving rod 31 from the connecting plate 21 without the need for screw installation.

[0039] Preferably, the longitudinal drive member also includes a support column 35 arranged below the connecting plate 21, and the support column 35 is equipped with a lifting cylinder 36 whose driving end is connected to the longitudinal driving rod 31. The lifting cylinder 36 is installed on the support column 35. The lifting cylinder 36 drives the longitudinal driving rod 31 to move up and down, thereby driving the connecting plate 21 to move up and down, so that the tooling 1 can be raised and lowered, and the installation and working height of the tooling 1 can be adjusted.

[0040] The mounting assembly 3 also includes a supporting base plate 37 and a guide shaft 4 installed longitudinally at intervals on the supporting base plate 37. The guide shaft 4 is slidably installed with a guide sleeve 41. The two sides of the connecting plate 21 are respectively connected to the guide sleeve 41. When the connecting plate 21 moves up and down, it moves axially along the guide shaft 4 through the guide sleeve 41, thereby ensuring the linear stability of its lifting and lowering movement and preventing lateral deviation.

[0041] The support base plate 37 is installed with a support sleeve 42 nested in the bottom of the guide shaft 4, and a limiting sleeve 40 is installed on the top of the support sleeve 42. A compression spring 43 nested in the guide shaft 4 is installed on the top of the limiting sleeve 40. The top of the compression spring 43 provides buffer support for the guide sleeve 41. During the lifting movement, when approaching the bottom, the compression spring 43 of the support sleeve 42 will elastically support the guide sleeve 41, reduce the collision between the guide sleeve 41 and the support sleeve 42, and protect the support sleeve 42 and the guide sleeve 41.

[0042] A support top plate 44 is also provided on the top of the guide shaft 4. The support top plate 44 is connected between the two guide shafts 4. A limit hole 45 is provided on the support top plate 44. A through sleeve 48 is coaxially installed on the limit hole 45. A limit seat 46 is installed on the support top plate 44. A limit shaft 47 that movably passes through the limit hole 45 and passes through the sleeve 48 is installed on the limit seat 46. A limit block 49 that cooperates with the stopper of the limit hole 45 is installed on the top and bottom of the limit shaft 47. The installation of the limit block 49 on the limit shaft 47 limits the longitudinal movement stroke of the limit shaft 47. The limit block 49 cooperates with the limit hole 45 and the stopper of the through sleeve 48. Therefore, this design can limit the lifting stroke of the connecting plate 21 to prevent the lifting cylinder 36 from exceeding the movement stroke.

[0043] In summary, it can be seen that the utility model has the above-mentioned excellent characteristics, which can enhance the performance unprecedented in the prior art and become a product with great practical value.
