[0053] This embodiment provides a processing device, including a CNC machine tool and a fixture. The fixture is disposed on the CNC machine tool and is used to clamp the workpiece to be processed. The CNC machine tool is used to process the workpiece.

[0054] For example, the workpiece to be processed can be a box-shaped workpiece with a free angle, such as a gearbox housing, engine block, turbine housing, hydraulic valve body, etc. The free angle of the workpiece specifically refers to the angle between the machining surface of the workpiece and the horizontal reference plane of the CNC machine tool.

[0055] Because the external contour of the workpiece to be processed is not a regular shape, it cannot be adapted to existing clamping devices, resulting in relatively low processing accuracy. Therefore, this embodiment provides a fixture, such as... Figure 1As shown, the fixture includes a base 4 and a positioning mechanism 1, a clamping mechanism 2, and a support mechanism 3 disposed on the base 4. The base 4 is mounted on a CNC machine tool, and the positioning mechanism 1, the clamping mechanism 2, and the support mechanism 3 are disposed on the base 4. The base 4 provides support for the positioning mechanism 1, the clamping mechanism 2, and the support mechanism 3, and the surface of the base 4 is flat to ensure a certain clamping accuracy.

[0056] The base 4 has at least one reference plane, which is parallel to the horizontal plane. The second direction is perpendicular to the plane and can also be called the vertical direction. The first direction and the third direction are two mutually perpendicular directions in the plane, and the first direction, the second direction, and the third direction are mutually perpendicular to each other. The first direction is identified by D1, the second direction by D2, and the third direction by D3.

[0057] Specifically, the support mechanism 3 includes a first support base 31, a second support base 32, a first adjusting member 33, and a second adjusting member 34. The first support base 31 and the second support base 32 are arranged in parallel and spaced apart along a first direction. Along a second direction, one end of the first adjusting member 33 is disposed on the first support base 31, and the other end is provided with a first supporting surface 331. One end of the second adjusting member 34 is disposed on the second support base 32, and the other end is provided with a second supporting surface 341. The first supporting surface 331 and the second supporting surface 341 are used together to support the workpiece to be processed.

[0058] For example, the first support 31 and the second support 32 can be directly welded to the base 4, and the first support 31 and the second support 32 can also be fixed to the base 4 by bolts.

[0059] For example, if the first adjusting member 33 is a cylindrical structure, the first supporting surface 331 is specifically the top surface of the first adjusting member 33 along the second direction; if the second adjusting member 34 is a cylindrical structure, the second supporting surface 341 is specifically the top surface of the second adjusting member 34 along the second direction. The first supporting surface 331 and the second supporting surface 341 are arranged in parallel, enabling the first supporting surface 331 and the second supporting surface 341 to more stably support the workpiece to be processed.

[0060] The first adjusting member 33 is configured to move relative to the first support 31 in a second direction, and the second adjusting member 34 is configured to move relative to the second support 32 in a second direction, so that the heights of the first support surface 331 and the second support surface 341 are different in the second direction.

[0061] For example, the first adjusting member 33 and the second adjusting member 34 can be bolts, such as hex bolts. By screwing on the first adjusting member 33, the height of the first adjusting member 33 protruding from the first support base 31 is adjusted so that the height of the first support surface 331 matches the corresponding contour shape of the workpiece to be processed; by screwing on the second adjusting member 34, the height of the second adjusting member 34 protruding from the second support base 32 is adjusted so that the height of the second support surface 341 matches the corresponding contour shape of the workpiece to be processed.

[0062] Specifically, the first support 31 and the second support 32 can be selected as cylindrical structures, such as cylinders, cuboids, etc. Figures 1-2 As shown, along the first direction, the horizontal distance between the central axis of the first support 31 and the central axis of the second support 32 is X, which can be called the lateral distance. The height of the first support 31 along the second direction is Y, which can be called the longitudinal distance. If the free angle of the workpiece to be processed is θ, for example, the free angle θ can be selected as the angle between the inclined surface and the reference surface, for example, a chamfer with an inclination angle of 30°; the free angle θ can be selected as the angle between the centerline axis of the inclined hole and the reference surface, for example, an inclined oil hole with an inclination angle of 15°. The free angle θ is a known input value. According to the formula, the height difference ΔY between the first support surface 331 of the first support 31 and the second support surface 341 of the second support 32 is ΔY = X·tan(θ). From this, it can be concluded that the second adjusting member 34 needs to adjust the height difference ΔY, thereby achieving precise positioning of the workpiece at any non-standard angle in the fixture.

[0063] The height difference ΔY is calculated according to the formula, and the actual height of the second support 32 is Y+ΔY. After precise positioning using the probe of the CNC machine tool, the height of the second support surface 341 of the second adjusting member 34 is adjusted so that the height of the second support surface 341 reaches the Y+ΔY position, thereby realizing the function of free angle adjustment of the fixture.

[0064] This method solves the problem of placing workpieces with free angles, improves the accuracy of positioning and alignment, and thus improves the processing efficiency of the workpieces.

[0065] In one embodiment, the heights of the first support 31 and the second support 32 are different along the second direction.

[0066] In this way, there is a certain height difference between the first support base 31 and the second support base 32, so that the first support surface 331 and the second support surface 341 initially have a certain height distance. The first adjusting member 33 and the second adjusting member 34 do not need to be adjusted in position, saving the labor burden of the operator.

[0067] In one embodiment, such as Figures 1-2As shown, the support mechanism 3 also includes a third support seat 35 and a fourth support seat 36. The third support seat 35 is located on the side of the first support seat 31 along the first direction and away from the second support seat 32. The fourth support seat 36 is disposed on the third support seat 35. An avoidance groove 351 is formed between the third support seat 35 and the fourth support seat 36. The avoidance groove 351 is used to avoid the workpiece to be processed.

[0068] The third support 35 can be directly welded to the base 4, and can also be fixed to the base 4 with bolts. The fourth support 36 can be directly welded to the third support 35, and can also be fixed to the third support 35 with bolts. The central axis of the third support 35 is set at an angle to the first direction, and the central axis of the third support 35 is set at an angle to the second direction, and the third support 35 is inclined away from the first support 31. The central axis of the fourth support 36 is set at an angle to the first direction, and the fourth support 36 is inclined towards the first support 31. Thus, the inclination directions of the third support 35 and the fourth support 36 are opposite, that is, a bending structure is formed between the third support 35 and the fourth support 36 to form a clearance groove 351 between the third support 35 and the fourth support 36. The clearance groove 351 provides a certain clearance space for the workpiece to be processed, so that the fixture can adapt to more workpieces with more contour shapes and improve its versatility.

[0069] like Figures 1-2 As shown, the support mechanism 3 also includes a third adjusting member 37. One end of the third adjusting member 37 is located on the side of the fourth support base 36 away from the third support base 35, and the other end of the third adjusting member 37 is provided with a third supporting surface 371, which is used to support the workpiece to be processed.

[0070] The third adjusting member 37 can be a bolt, such as a hex bolt. By screwing the third adjusting member 37, the height of the third adjusting member 37 protruding from the fourth support base 36 can be adjusted so that the height of the third support surface 371 matches the corresponding contour shape of the workpiece to be processed.

[0071] Along the second direction, the third support surface 371 and the first support surface 331 have different heights, and the third support surface 371 and the second support surface 341 have different heights. That is, the first support surface 331, the second support surface 341 and the third support surface 371 have different heights. The three support points with different heights can support the workpiece at different height positions, further improving the support effect.

[0072] The third support surface 371 and the first support surface 331 are set at an angle. With this setting, the first support surface 331 and the third support surface 371 can fit against different sides of the workpiece to be processed, thereby improving the support effect of the support mechanism 3 on the workpiece to be processed.

[0073] If the size and shape of the workpiece to be processed are relatively large, the workpiece will protrude from the outside of the positioning mechanism 1, causing the part of the workpiece to be processed outside the positioning mechanism 1 to be suspended in the air, which can easily lead to inaccurate positioning.

[0074] Therefore, such as Figures 1-2 As shown, the support mechanism 3 also includes a support column 38, which is located on the side of the positioning mechanism 1 along the third direction and away from the support mechanism 3. The support column 38 is detachably connected to the positioning mechanism 1.

[0075] For example, the support column 38 is provided with a thread at its bottom along the second direction, and the positioning mechanism 1 is provided with a threaded hole corresponding to the support column 38. The support column 38 passes through the threaded hole, which facilitates the installation and disassembly of the support column 38.

[0076] If the outline of the workpiece to be processed does not protrude beyond the positioning mechanism 1, the support column 38 is removed from the positioning mechanism 1 to reduce the space occupied; if the outline of the workpiece to be processed protrudes beyond the positioning mechanism 1, the support column 38 is installed on the outside of the positioning mechanism 1 so that the support column 38 assists in supporting the workpiece to be processed, avoiding the situation of local collapse of the workpiece to be processed, improving the support effect of the support mechanism 3, avoiding vibration of the workpiece to be processed during processing, and facilitating the operator to quickly clamp and align the workpiece to be processed.

[0077] Alternatively, the support column 38 can be detachably connected to the base 4. The support column 38 has threads at its bottom along the second direction, and the base 4 has threaded holes through which the support column 38 passes, facilitating its installation and removal. It is understandable that multiple support columns 38 can be selected, with some detachably connected to the positioning mechanism 1 and others detachably connected to the base 4.

[0078] In one embodiment, such as Figures 1-2 As shown, the positioning mechanism 1 includes a first positioning seat 11, a second positioning seat 12, and a first positioning member 13. The first positioning seat 11 is located on one side of the support mechanism 3 along a third direction; the second positioning seat 12 is located on the other side of the support mechanism 3 along a third direction. One end of the first positioning member 13 is disposed in at least one of the first positioning seat 11 and the second positioning seat 12, and the other end of the first positioning member 13 passes through the workpiece to be processed.

[0079] For example, the first positioning seat 11 and the second positioning seat 12 extend as a whole along the second direction, and are arranged and opposite to each other along the third direction. The first positioning seat 11 and the second positioning seat 12 can be referred to as the front upright plate and the rear upright plate, respectively. The first positioning seat 11, the second positioning seat 12 and the third support seat 35 surround the first support seat 31 and the second support seat 32, so that the first positioning seat 11, the second positioning seat 12 and the third support seat 35 form a semi-enclosed structure to ensure that multiple sides of the workpiece to be processed can be positioned or supported.

[0080] For example, the first positioning seat 11 and the second positioning seat 12 may be provided with grooves, which are used to avoid the workpiece to be processed or other mechanical components on the CNC mechanism, and can also play a role in reducing weight to a certain extent.

[0081] For example, the first positioning element 13 may be a positioning pin, and the first positioning element 13 is fixedly disposed on the first positioning seat 11 and / or the second positioning seat 12. The first positioning element 13 may be referred to as a fixed positioning element. The first positioning element 13 may abut against the side wall of the workpiece to be processed; alternatively, the workpiece to be processed may be provided with a first positioning hole, and the first positioning element 13 may pass through the first positioning hole of the workpiece to be processed, thereby improving the positioning effect of the workpiece to be processed.

[0082] The number of first positioning elements 13 can be multiple, and multiple first positioning elements 13 are respectively set on the first positioning seat 11 and the second positioning seat 12. The arrangement of multiple first positioning elements 13 can be adjusted according to the specific shape and structure of the workpiece to be processed.

[0083] In one embodiment, such as Figures 1-2 As shown, the positioning mechanism 1 also includes a second positioning element 14 and a positioning drive source 15. The second positioning element 14 is disposed in at least one of the first positioning seat 11 and the second positioning seat 12. The output end of the positioning drive source 15 is connected to one end of the second positioning element 14. The positioning drive source 15 can drive the second positioning element 14 to move in a third direction, so that the other end of the second positioning element 14 is disposed in the workpiece to be processed.

[0084] For example, the second positioning element 14 may be a positioning pin, and the second positioning element 14 passes through the first positioning seat 11 and / or the second positioning seat 12. The second positioning element 14 may be driven by the positioning drive source 15, and the second positioning element 14 may be referred to as a movable positioning element. The positioning drive source 15 may be a motor, cylinder, etc., and the positioning drive source 15 may directly drive the second positioning element 14 to move in a third direction; the positioning drive source 15 may also be a handle, with the second positioning element 14 and the first positioning seat 11 threadedly engaged. The operator rotates the handle to make the second positioning element 14 rotate relative to the first positioning seat 11. As the second positioning element 14 rotates, the second positioning element 14 can move relative to the first positioning seat 11, so that the second positioning element 14 can abut against the side wall of the workpiece to be processed; alternatively, the workpiece to be processed may be provided with a second positioning hole, and the second positioning element 14 passes through the second positioning hole of the workpiece to be processed, thereby improving the positioning effect of the workpiece to be processed.

[0085] The number of positioning drive sources 15 and second positioning components 14 can be multiple. Multiple positioning drive sources 15 and multiple second positioning components 14 are set accordingly. Multiple second positioning components 14 are respectively set on the first positioning seat 11 and the second positioning seat 12. The arrangement of multiple second positioning components 14 can be adjusted according to the specific shape and structure of the workpiece to be processed.

[0086] In one embodiment, such as Figure 1 As shown, the clamping mechanism 2 includes a screw 21, a clamping member 22, and a locking member (not shown in the figure). The screw 21 is disposed on the positioning mechanism 1 and extends along the second direction. The clamping member 22 is sleeved on the outside of the screw 21. The locking member is sleeved on the outside of the screw 21 and can rotate relative to the screw 21 and abut against the clamping member 22, so that the side of the clamping member 22 away from the locking member abuts against the workpiece to be processed.

[0087] The locking element can be a nut. By tightening the locking element, its position relative to the screw 21 along the second direction can be adjusted. The locking element presses against the workpiece through the clamping element 22. The contact area between the clamping element 22 and the workpiece is relatively large, which improves the clamping effect while reducing the pressure that could damage the workpiece, thus protecting it. The screw 21 extends along the second direction, and the locking element can move along the extension direction of the screw 21, allowing the clamping element 22 to clamp the workpiece at any height, ensuring a secure hold. The clamping effect is achieved through the cooperation between the screw 21 and the locking element, resulting in a simple structure and convenient use.

[0088] In one embodiment, the clamping member 22 is provided with a receiving groove 221 on the side facing the screw 21, and the screw 21 passes through the receiving groove 221.

[0089] The receiving groove 221 can be a strip groove. The receiving groove 221 can extend from the clamping member 22 along the third-direction side wall into the interior of the clamping member 22. The operator can insert the screw 21 into the clamping member 22 through the groove opening of the receiving groove 221, which facilitates the installation between the clamping member 22 and the screw 21.
