Description

Technical Field

[0001] The utility model relates to the field of mechanical processing, in particular to a tilting processing fixture. Background Art

[0002] With the rapid development of the industrial field, enterprises have higher and higher requirements for mechanical processing, and the processing needs are becoming more and more diversified. For example, processing oblique holes and oblique grooves on workpieces is a common processing demand at present. At present, there are generally two processing methods for processing oblique holes and oblique grooves: one is to use four-axis, five-axis and other multi-axis machine tools for processing, but because four-axis, five-axis and other multi-axis machine tools are relatively expensive, enterprises purchase fewer and generally only use them for key workpieces or high-value workpieces; another more common processing method is to use three-axis machine tools, with the help of fixtures, to tilt the workpiece according to the designed angle (referring to placing it at a certain angle to the horizontal plane) and then process it.

[0003] At present, the more conventional operation method is to use Figure 1 The vise 6 shown in the figure is used to tilt and fix the workpiece 5. Figure 2 As shown, through trigonometric calculation, the micrometer 7 gauge length L plus the drop value H is calculated to get the inclination angle α which is consistent with the processing and can be processed.

[0004] The above common method of using three-axis machine tools and vises 6 to tilt and fix the workpiece 5 for processing has the following problems: (1) Since the vise 6 fixes the workpiece 5 by clamping the workpiece 5 with the sliders 61 on both sides, the bottom of the workpiece 5 is suspended during processing. When the inclined hole or inclined groove is processed, the workpiece 5 is easy to loosen, which will cause quality and safety accidents; (2) Due to the clamping range of the vise 6, the size of the workpiece 5 that can be processed is relatively limited, and it cannot solve the processing problem of large workpieces, and its applicability is not high; (3) Since the calibration time is very long, it takes 15 to 20 minutes for an intermediate technician to calibrate a slope, and the operation time for a junior technician is even longer, which affects the processing efficiency.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] like Figure 3 As shown, the utility model provides a tilting processing fixture, which includes a base 1, a workpiece fixing plate 2, an adjustment component 3 and a fixing component 4; the workpiece fixing plate 2 is arranged on the base 1, and the adjustment component 3 is used to adjust the relative horizontal tilt angle between the workpiece fixing plate 2 and the base 1; the workpiece fixing plate 2 is used to place a workpiece 5 to be processed, and the fixing component 4 is arranged on the workpiece fixing plate 2, and the fixing component 4 is used to fix the workpiece 5 so that it is fixed during the processing process.

[0025] The above-mentioned adjustment component 3 can have multiple implementation schemes. For example, two groups of lifting devices are arranged between the workpiece fixing plate 2 and the base 1, and the two groups of lifting devices are relatively arranged on both sides of the workpiece fixing plate 2 and the base 1, and can respectively control the lifting heights of the two sides of the workpiece fixing plate 2. By setting the two groups of lifting heights differently, the relative horizontal inclination angle between the workpiece fixing plate 2 and the base 1 can be adjusted; for example, one end of the workpiece fixing plate 2 and the base 1 is connected by a rotating shaft or a hinge so that the workpiece fixing plate 2 can rotate around the rotating shaft or the hinge, and the other end is connected by a supporting component such as a height-adjustable support column or a support arm. By adjusting the supporting components such as the support column or the support arm, the relative horizontal inclination angle between the workpiece fixing plate 2 and the base 1 can be adjusted.

[0026] The bevel machining fixture with the above structure is used, and the workpiece 5 to be machined is fixed on the workpiece fixing plate 2 by the fixing component 4, and the relative horizontal inclination angle between the workpiece fixing plate 2 and the base 1 can be adjusted by the adjusting component 3, which can better meet the needs of three-axis machine tools for machining inclined holes and inclined grooves of different angles. Compared with the vise 6 tooling method used in the prior art, the workpiece 5 to be machined is fixed on the workpiece fixing plate 2 in a close-fitting manner, rather than with the bottom suspended in the air. Therefore, it is not easy for the workpiece 5 to loosen during machining, which can reduce the probability of quality accidents and safety accidents, and has better reliability. In addition, since the workpiece 5 to be machined is placed on the workpiece fixing plate 2 and then fixed by the fixing component, rather than being clamped and fixed by sliders on both sides like the vise 6, there is no limitation on the clamping range. In addition to processing small workpieces 5, large workpieces 5 can also be processed, which has higher applicability.

[0027] In some embodiments, the adjustment component 3 includes a support arm 31 and an angle adjustment plate 32; the support arm 31 is fixed on the base 1, and the angle adjustment plate 32 is fixed under the workpiece fixing plate 2; one end of the angle adjustment plate 32 is connected to the support arm 31 through a rotating shaft 33, and the other end can move up and down; as a more preferred embodiment, there are two support arms 31, and the two support arms 31 are fixed on the base 1 in parallel, forming a receiving groove in the middle, and the angle adjustment plate 32 is provided in the receiving groove, the angle adjustment plate 32 is fixed under the workpiece fixing plate 2, and one end of the angle adjustment plate 32 is connected to the two support arms 31 through a rotating shaft 33, and the other end can move up and down in the receiving groove. The adjustment component 3 also includes a locking mechanism 34, and the locking mechanism 34 can fix the angle adjustment plate 32 relative to the support arm 31.

[0028] In the beveling processing fixture with the above structure, the support arm 31 is fixed on the base 1 to play a fixing role, and the angle adjustment plate 32 is fixed under the workpiece fixing plate 2, and one end of the angle adjustment plate 32 is connected to the support arm 31 through the rotating shaft 33, and the other end can move up and down.

[0033] In some embodiments, Figure 4 As shown, a plurality of through holes 342 on the support arm 31 are marked with angle values ​​correspondingly, and the angle value is the relative horizontal tilt angle between the angle adjustment plate 32 and the base 1 when the movable pin 341 is inserted into the through hole 342 .

[0034] With the beveling processing fixture of the above structure, since the several through holes 342 on the support arm 31 have been preset and the angles have been marked, the fixture can be quickly adjusted to the required beveling angle according to the beveling angle required for processing the workpiece 5, further shortening the time for adjusting the beveling angle and improving processing efficiency.

Therefore, the position and number of the fixing clamping mechanism 41 can be determined according to the size of the workpiece 5 to be processed, which is more convenient for clamping the workpiece 5.

[0039] In some embodiments, the fixing assembly 4 also includes a plurality of limit pins 42, and the limit pins 42 are arranged at the root of the workpiece fixing plate 2 (i.e., the end with a lower height when the workpiece fixing plate 2 is tilted), and the diameter of the limit pins 42 is adapted to the inner diameter of the fixing hole 21 and can be inserted into the fixing hole 21.

[0040] The tilting machining fixture with the above structure, in addition to using the clamping mechanism 41 to clamp the workpiece 5, is also provided with a limit pin 42 at the root of the workpiece fixing plate 2 to prevent the workpiece 5 from sliding down during machining, further improving the reliability of the fixture and enhancing the machining quality.
