Description

Technical Field

[0001] This utility model belongs to the field of waterjet cutting technology, and in particular relates to a fixed fixture for ultra-high pressure waterjet cutting. Background Technology

[0002] CNC ultra-high pressure waterjet cutting technology is favored for its cold cutting technique, which does not alter the physical and chemical properties of materials, and has been widely applied in numerous industries such as ceramics, stone, glass, metal, and composite materials. However, existing CNC ultra-high pressure waterjet cutting processes suffer from various challenges. For example, irregularly shaped cutting blanks or blanks that are too small affect the stability of pre-cutting fixation and pose a risk of falling into the water tank. Unstable fixation leads to substandard cutting accuracy, reduced yield, and increased production burden. Furthermore, blanks falling into the water tank are difficult to retrieve due to sand and gravel accumulation and the high pressure of the ultra-high pressure waterjet cutter, increasing labor and time costs and impacting production efficiency. Developing specific fixtures for different shapes is time-consuming and labor-intensive. Replacing the grid in the water tank to prevent falling is expensive and overly complex. Therefore, a fixture is needed that can solve the problem of fixing various irregularly shaped blanks, prevent finished products from falling into the water tank, and is convenient and practical. Utility Model Content

[0003] To address the problems existing in the prior art, this utility model provides the following technical solution:

[0004] The fixture for ultra-high pressure water jet cutting includes an annular seat, two sets of support plates, two sets of fixed legs, and two sets of axially adjustable components. The blank to be cut can be clamped and fixed in the annular seat by one end of the axially adjustable components located at the top and bottom, respectively. The other end of each set of axially adjustable components is fixed to the center of a set of support plates. The two ends of each set of support plates are slidably connected to the opening of the annular seat. The two sets of fixed legs are fixed to the periphery of the annular seat and are respectively provided with insertion ports at the bottom.

[0005] Furthermore, the upper and lower opening ends of the annular seat sleeve are respectively formed with a set of T-shaped slide rails extending annularly along the opening ends. Each set of T-shaped slide rails is slidably connected to both ends of a set of support plates, and the plates of the support plates extend radially along the annular seat sleeve, thereby dividing the opening of the annular seat sleeve into two halves. The middle part of the plate of the support plate is located on the axis of the annular seat sleeve, and the sliding trajectory formed by the extension direction of the T-shaped slide rails is circular, and the circle is coaxial with the annular seat sleeve.

[0006] Furthermore, each end of the support strip is fitted with a pair of groove blocks, each groove block having a sliding groove. The upper surfaces of the two groove blocks can be fixed to the ends of the support strip by bolts. One groove block in each pair is located in the inner ring, and the other groove block is located in the outer ring. The sliding grooves of the two groove blocks face each other to form a T-shaped groove that matches the T-shaped slide rail, thereby clamping the T-shaped slide rail and sliding it with it, and preventing the support strip from coming off.

[0007] Furthermore, a mounting boss is radially protruding on the outer circumference of the annular seat sleeve, and the upper part of the fixed leg is fixed to the mounting boss by fastening bolts.

[0008] Furthermore, each axially adjustable component includes a connecting seat, which is fixed to the center of the support bar plate. The connecting seat supports one end of the first connecting rod. The first connecting rod, the threaded sleeve, and the second connecting rod are coaxially connected in sequence to form an adjustable component whose overall length in the axial direction is adjustable and lockable.

[0009] Furthermore, the other end of the first connecting rod is a threaded section with external threads, the threaded sleeve has a threaded inner hole, and one end of the second connecting rod is a threaded section with external threads. The threaded sections of the first and second connecting rods are respectively fitted into the threaded sleeve and threadedly connected to it.

[0010] Furthermore, each set of axially adjustable components is also connected to a pressure head at the other end of the second connecting rod.

[0011] Furthermore, the pressure head and the second connecting rod are connected by a bearing assembly for rotational support.

[0012] Furthermore, a friction pad is installed on the end face of the pressure head facing the blank.

[0013] The fixing fixture provided by this utility model is suitable for cutting blanks of different shapes by adjusting the knob. It has the functions of fixing and preventing falling, which can improve product accuracy and quality, reduce tooling production time and cost, improve machine and personnel utilization, and increase product profits.

[0023] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] like Figure 1 As shown, this utility model includes an annular seat sleeve 1, two sets of support plates 2, two sets of fixed legs 3, and two sets of axially adjustable components 4.

[0026] The annular sleeve 1 has a set of T-shaped slide rails 11 extending annularly along the upper and lower openings of its sleeve. Each set of T-shaped slide rails 11 is slidably connected to both ends of a set of support plates 2. The plates of the two sets of support plates 2 extend radially along the annular sleeve 1, meaning that the support plates 2 divide the upper and lower openings of the annular sleeve 1 into two halves. The water jet can enter from one of the two halves to cut the blank inside the annular sleeve 1. In addition, the middle part of the support plate 2 is located at the axis of the annular sleeve 1. Online, the sliding trajectory formed by the extension direction of the T-shaped slide rail 11 is circular, and the circle is coaxial with the annular seat 1. Therefore, the plate of each set of support strips 2 can rotate around the axis of the annular seat 1 and its own middle part under the sliding guidance and constraint of the matching T-shaped slide rail 11. Therefore, by turning the upper or lower support strips 2, the water jet can be moved to the required position, avoiding the restriction and influence of the plate of the support strips 2 on the working area of ​​the water jet, and also preventing the water jet from damaging the support strips 2.

[0027] Furthermore, this utility model provides a simple, reliable, and easy-to-disassemble installation structure for the sliding connection between the two ends of the support plate 2 and the T-shaped slide rail 11: Each end of the support plate 2 is fitted with a pair of slotted blocks 21. The two slotted blocks 21 are independent (i.e., not integral). Each slotted block 21 has a groove that matches the T-shaped slide rail 11. The upper surfaces of the two slotted blocks 21 are respectively bolted to the ends of the support plate 2. One slotted block 21 in each pair is located in the inner ring, and the other slotted block 21 is located in the outer ring. The grooves of the two slotted blocks 21 face each other to form a T-shaped groove that matches the T-shaped slide rail, thereby clamping and slidingly connecting the T-shaped slide rail 11 and preventing the support plate 2 from coming off. When it is necessary to separate the support plate 2 from the annular seat 1, it is usually only necessary to remove the slotted block 21 located in the inner ring from the support plate 2 to move the support plate 2 horizontally away from the T-shaped slide rail 11. Installation is done in reverse, which is convenient and quick.

[0028] As shown in the figure, a set of fixed legs 3 are fixedly connected to the two opposite sides of the outer circumference of the annular seat 1. Each set of fixed legs 3 protrudes downward from the annular seat 1 and has a socket 31 at the bottom. They are fixed to the annular seat 1 by bolts 5. The two sets of fixed legs are inserted into the waterjet grid through the sockets 31, thereby fixing the entire fixture on the waterjet cutting plane. To further enhance the stability of the entire fixture on the waterjet grid, the fixed legs 3 installed on the annular seat 1 can also be configured as three sets (not shown in the figure), evenly distributed around the circumference of the annular seat 1, or arranged in a T-shape, that is, two sets are located on the opposite sides of the annular seat 1, and the other set is located perpendicular to the line connecting the two sets.

[0029] Furthermore, to avoid interference or obstruction of the rotation of the support plate 2 by the fixed leg 3, a mounting boss 12 is radially protruding on the outer circumferential surface of the annular seat 1, and the upper part of the fixed leg 3 is fixedly mounted on the mounting boss 12. Preferably, the upper part of the fixed leg 3 is fixed to the mounting boss 12 by fastening bolts, which facilitates installation and disassembly.

[0030] The blank to be cut is clamped and fixed within the annular seat 1 by axially adjustable components 4 located at the upper and lower parts respectively. Specifically, as shown... Figures 1 to 3As shown, each set of support plates 2 has an axially adjustable component 4 fixedly connected to the center of its surface. Each axially adjustable component 4 includes a connecting seat 41, which is fixed to the center of the support plate 2 by fastening bolts 42. The connecting seat 41 and one end of the first connecting rod 44 are rotatably connected by a bearing assembly 43, and the position of the first connecting rod 44 relative to its axis is fixed. The first connecting rod 44, the screw sleeve 45, and the second connecting rod 46 are coaxially connected in sequence to form an axially adjustable and lockable adjustment assembly. Specifically, the first connecting rod 44... The other end of 4 is a threaded section with external threads. The threaded sleeve 45 has a threaded inner hole. One end of the second connecting rod 46 is a threaded section with external threads. The threaded sections of the first connecting rod 44 and the second connecting rod 46 are respectively fitted into the threaded sleeve 45 and threadedly connected to it. By rotating at least one of the three, the overall length of the adjusting component in the axial direction can be adjusted and locked. At the same time, since each of the upper and lower support plates 2 is connected to a pair of axially adjustable components 4 arranged in opposite directions, each set of axially adjustable components 4 can be adjusted and locked, thereby achieving clamping and fixing of blanks to be cut for different thicknesses.

[0031] Furthermore, such as Figure 4 In another embodiment shown, each set of axially adjustable components 4 can also match and replace different contoured pressure heads 47 at the other end of the second connecting rod 46 (i.e., the end facing the blank) according to the different surface shapes of the blank, thereby increasing the working area for better clamping and fixing. Preferably, the pressure head 47 and the second connecting rod 46 are also supported and rotated through a bearing assembly 48.

[0032] Furthermore, a friction pad 49 is installed on the end face of the pressure head 47 facing the blank, which has a certain elasticity and friction to better adapt to the irregular surface of the blank, avoid damage to the surface of the blank and enhance the reliability of clamping and fixing.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
