[0023] like Figures 1 to 4As shown, the positioning fixture for a square box motor base according to an embodiment of the present invention includes: a base plate 1, a first positioning mechanism 2, a second positioning mechanism 3, a third positioning mechanism 4, and a fourth positioning mechanism 5; the base plate 1 is used to be mounted on the worktable 100 of a floor-type boring and milling machining center; the first positioning mechanism 2, the second positioning mechanism 3, the third positioning mechanism 4, and the fourth positioning mechanism 5 are arranged in a rectangle on the base plate 1, and are respectively used for positioning and connecting with the four bottom corners of the base 200, wherein the first positioning mechanism 2 is arranged diagonally relative to the fourth positioning mechanism 5, and the second positioning mechanism 3 is arranged diagonally relative to the third positioning mechanism 4; the first positioning mechanism 2 is fixedly mounted... The second positioning mechanism 3 is movably disposed on the base plate 1 along the X direction, the third positioning mechanism 4 is movably disposed on the base plate 1 along the Y direction, and the fourth positioning mechanism 5 is movably disposed on the base plate 1 along both the X and Y directions. The first positioning mechanism 2, the second positioning mechanism 3, the third positioning mechanism 4, and the fourth positioning mechanism 5 each include a positioning clamping assembly 6. The positioning clamping assembly 6 includes a pressure block 61 and an adjustable support 62. The adjustable support 62 is used to abut against the bottom of the base 200, and the pressure block 61 is used to extend into the corresponding positioning hole 2001 on the base 200 and press the base 200.

[0024] In this embodiment, in conjunction with the appendix Figure 1 To be continued Figure 4 As shown, the positioning fixture for the square box motor base of the present invention can complete all processing steps of the square box motor base using a single machine and a single clamping process, thus avoiding the cumulative errors caused by multiple transfers and clamping. This not only improves the machining accuracy of the dimensions and shape of the square box motor base, but also increases the machining efficiency. Specifically, the operator can hoist the base plate 1 as a whole and place it on the worktable 100 of the floor-type boring and milling machining center. Then, according to the external positioning dimensions of the machine base 200, adjust the second positioning mechanism 3, the third positioning mechanism 4, and the fourth positioning mechanism 5 to their respective designated positions. Then, hoist the machine base 200 onto the adjustable supports 62 of the corresponding positioning clamping components 6 on the first positioning mechanism 2, the second positioning mechanism 3, the third positioning mechanism 4, and the fourth positioning mechanism 5. That is, the four adjustable supports 62 are respectively supported at the four bottom corners of the machine base 200. Then, insert the pressure blocks 61 of the corresponding positioning clamping components 6 on the first positioning mechanism 2, the second positioning mechanism 3, the third positioning mechanism 4, and the fourth positioning mechanism 5 into the corresponding positioning holes 2001 on the machine base 200 and press the machine base 200. In this way, the machine base 200 is fixed and pressed. Then, the machine base 200 can be processed by the floor-type boring and milling machining center.

[0025] It should be noted that, since the base 200 is rectangular in shape, the difference between different models of base 200 lies in their external dimensions, i.e., the size of the rectangle. Therefore, the first positioning mechanism 2, the second positioning mechanism 3, the third positioning mechanism 4, and the fourth positioning mechanism 5 of this invention are arranged rectangularly on the base plate 1. In order for this positioning fixture to be adaptable to different models of base 200, the first positioning mechanism 2 is fixedly mounted on the base plate 1, and the second positioning mechanism 3 is mounted along the X direction (see attached diagram). Figure 1 Or attached Figure 3 The third positioning mechanism 4 is movably mounted on the base plate 1 along the X-axis direction, and is located along the Y-axis direction (attached). Figure 1 Or attached Figure 3 The first positioning mechanism 2 is movably mounted on the base plate 1 along the Y-axis direction, and the second positioning mechanism 3 is movably mounted on the base plate 1 along the X and Y directions respectively. The first positioning mechanism 2 is diagonally arranged relative to the fourth positioning mechanism 5, and the second positioning mechanism 3 is diagonally arranged relative to the third positioning mechanism 4. In this way, by adjusting the positions of the second positioning mechanism 3, the third positioning mechanism 4 and the fourth positioning mechanism 5, the size of the rectangle formed by the first positioning mechanism 2, the second positioning mechanism 3, the third positioning mechanism 4 and the fourth positioning mechanism 5 can be adjusted to adapt to different models of base 200.

[0026] Optionally, the positioning and clamping assembly 6 further includes a base block 63, a first screw 64, and a hydraulic push rod 65. The first screw 64 is threaded vertically to the base block 63. The pressure block 61 is located above the base block 63 and has an elongated slot. The first screw 64 passes through the elongated slot. A nut is threaded onto the first screw 64, and the nut is used to abut against the end face of the pressure block 61 opposite to the base block 63. The adjustable support 62 is arranged vertically on the base block 63 and located... The base block 63 is located at one end near the base 200. The hydraulic push rod 65 is arranged vertically on the base block 63 and located at the end of the base block 63 away from the base 200. The end of the pressure block 61 near the base 200 is used to extend into the corresponding positioning hole 2001 on the base 200. The hydraulic push rod 65 is used to push the end of the pressure block 61 away from the base 200 upward, so that the end of the pressure block 61 near the base 200 presses the base 200 downward.

[0027] Specifically, in conjunction with the appendix Figure 2 As shown, the lower end of the first screw 64 (attached) Figure 1 Or attached Figure 3The first screw 64 is threaded to the base block 63 in the Z-axis direction. The upper part of the first screw 64 passes through the long slot hole on the pressure block 61. In this way, on the one hand, the pressure block 61 can adjust its height position relative to the base block 63 along the length direction of the first screw 64. The nut on the first screw 64 can limit the height position of the pressure block 61 relative to the base block 63. On the other hand, the pressure block 61 can move towards or away from the machine base 200 under the action of its long slot hole. That is, the pressure block 61 can be manually inserted into the corresponding positioning hole 2001 on the machine base 200. Then, the end of the pressure block 61 away from the machine base 200 is pushed upward by the hydraulic push rod 65, so that the end of the pressure block 61 inserted into the positioning hole 2001 of the machine base 200 can press the machine base 200 downward. Both the pressure block 61 and the base block 63 can be rectangular block structures. One end of the pressure block 61, which is inserted into the positioning hole 2001 of the machine base 200, can be threaded with a cylindrical block. This cylindrical block can be positioned directly above the adjustable support 62, which can be a screw structure, extending vertically (see attached diagram). Figure 1 (In the Z-axis direction) threaded connection to the base block 63. Since the adjustable support 62 needs to support the machine base 200, before the machine base 200 is placed on the adjustable support 62, the pressure block 61 needs to be adjusted to move away from the adjustable support 62 to avoid interference between the cylindrical block on the pressure block 61 and the machine base 200. After the machine base 200 is placed on the adjustable support 62, the pressure block 61 can be moved closer to the machine base 200 and inserted into the positioning hole 2001 of the machine base 200.

[0028] In this embodiment, the force application point of the pressure block 61 is designed directly above the adjustable support 62, so that the clamping force can be applied directly and evenly to the workpiece (machine base 200). At the same time, a hydraulic control system can be introduced to precisely adjust and control the clamping force of the hydraulic push rod 65, ensuring that the clamping force is sufficient to fix the workpiece, but will not cause clamping deformation of the square box motor base due to excessive clamping. This effectively ensures the processing accuracy and quality of the workpiece and avoids scrap and defective products caused by improper clamping.

[0029] Optionally, the positioning and clamping assembly 6 further includes a base 66, on which a sliding groove is provided, and a slider is provided on the end face of the base block 63 opposite to the pressure block 61, the slider being slidably connected to the sliding groove.

[0030] In this embodiment, in conjunction with the appendix Figure 2 As shown, the positioning and clamping assembly 6 also includes a base 66. A groove is formed on the upper surface of the base 66, and a slider is provided on the lower surface of the base block 63. The base block 63 can be slidably connected to the groove on the base 66 via the slider. The extension direction of the groove on the base 66 is as follows: Figure 1 In the Y-axis direction, the base block 63 can be adjusted in position to ensure that the pressure block 61 can be smoothly inserted into the positioning hole 2001 of the base 200.

[0031] It should be noted that the bases 66 corresponding to the first positioning mechanism 2, the second positioning mechanism 3, the third positioning mechanism 4, and the fourth positioning mechanism 5 differ in height and / or width. For example, the first positioning mechanism 2 is fixedly mounted on the base plate 1, and the lower end of the base 66 corresponding to the first positioning mechanism 2 is connected to the base plate 1. Therefore, the height of the base 66 corresponding to the first positioning mechanism 2 is greater than that of the second positioning mechanism 3, the third positioning mechanism 4, and the fourth positioning mechanism 5.

[0032] Optionally, positioning rods 7 are respectively provided on the base 66 corresponding to the first positioning mechanism 2 and the second positioning mechanism 3, and the two positioning rods 7 are respectively used to abut against the rear end face of the base 200; fixing plates 8 are respectively provided on the base 66 corresponding to the first positioning mechanism 2 and the third positioning mechanism 4, and the two fixing plates 8 are respectively used to abut against the right end face of the base 200.

[0033] In this embodiment, in conjunction with the appendix Figure 1 As shown, positioning rods 7 are respectively provided on the bases 66 corresponding to the first positioning mechanism 2 and the second positioning mechanism 3. The two positioning rods 7 are respectively used to abut against the rear end face of the machine base 200, and play the role of positioning the rear end face of the machine base 200. Fixing plates 8 are respectively provided on the bases 66 corresponding to the first positioning mechanism 2 and the third positioning mechanism 4. The two fixing plates 8 are respectively used to abut against the right end face of the machine base 200, and play the role of positioning the right end face of the machine base 200.

[0034] Optionally, a first hydraulic cylinder 9 is provided on the base 66 corresponding to the second positioning mechanism 3. The first hydraulic cylinder 9 is used to adjust the height difference between the left and right ends of the base 200.

[0035] In this embodiment, in conjunction with the appendix Figure 1 and attached Figure 3 As shown, a first hydraulic cylinder 9 is provided on the base 66 corresponding to the second positioning mechanism 3. The telescopic end of the first hydraulic cylinder 9 can abut against the bottom of the left end of the machine base 200 to adjust the height difference between the left and right ends of the machine base 200.

[0036] Optionally, the positioning and clamping assembly 6 further includes a second screw 67 and a third screw 68. The second screw 67 is threaded vertically to the base block 63, and the end of the second screw 67 away from the base block 63 is used to abut against the pressure block 61. The third screw 68 is threaded vertically to the pressure block 61, passes through the pressure block 61, and is coaxially arranged with the hydraulic push rod 65. The hydraulic push rod 65 is used to push the third screw 68 to lift the end of the pressure block 61 away from the base 200 upward.

[0037] In this embodiment, in conjunction with the appendix Figure 2 As shown, the second screw 67 is along the vertical direction (see attached diagram). Figure 1 A second screw 67 is threaded to the base block 63 along the Z-axis, and is located between the hydraulic jack 65 and the first screw 64. The upper end of the second screw 67 is used to abut against the pressure block 61, which can limit the distance between the pressure block 61 and the base block 63. A third screw 68 is threaded to the pressure block 61 in the vertical direction, and the lower end of the third screw 68 passes through the pressure block 61. The third screw 68 is coaxially arranged with the hydraulic jack 65. Since the stroke of the hydraulic jack 65 is limited, the end of the pressure block 61 away from the machine base 200 can be indirectly lifted upward through the third screw 68.

[0038] Optionally, the second positioning mechanism 3 further includes a first guide rail 31, a first slide 32, and a first driving mechanism 33. The first guide rail 31 is arranged on the base plate 1 along the X direction. The first slide 32 is slidably connected to the first guide rail 31. The positioning clamping assembly 6 is provided on the first slide 32. The first driving mechanism 33 is provided on the base plate 1 and is used to drive the first slide 32 to move along the first guide rail 31.

[0039] Specifically, in conjunction with the appendix Figure 1 As described above, two first guide rails 31 are arranged at intervals on the base plate 1, wherein the extension direction of the first guide rails 31 is the X direction, i.e., attached... Figure 1 In the X-axis direction, the first slide 32 is slidably connected to two first guide rails 31. The upper end surface of the first slide 32 is provided with a positioning and clamping assembly 6. The base plate 1 is provided with a first driving mechanism 33 for driving the first slide 32 to move along the first guide rails 31.

[0040] In this embodiment, the first drive mechanism 33 may include a lead screw and a servo motor system. The first slide 32 is connected to the lead screw, and the servo motor system is driven by the lead screw to rotate and move the first slide 32. The high-precision servo motor system precisely drives the first slide 32, achieving rapid and accurate positioning of the first slide 32. The servo motor features high response speed and high control precision, ensuring that the first slide 32 accurately reaches the target position in a very short time, with a positioning accuracy within ±0.1 mm. Simultaneously, the system may be equipped with a self-locking device. Once the first slide 32 reaches the set position, the self-locking device quickly activates and firmly locks the first slide 32, preventing displacement due to external forces during processing. This ensures the stability and reliability of the processing, providing crucial support for the tooling to achieve universal, flexible, and digital tooling changeover.

[0041] It should be noted that the second drive mechanism 43, the third drive mechanism 55, the fourth drive mechanism 56, the fifth drive mechanism 104, and the sixth drive mechanism 105 mentioned later have the same structure and function as the first drive mechanism 33, and will not be described again in the following text.

[0044] Optionally, the fourth positioning mechanism 5 further includes a third guide rail 51, a fourth guide rail 52, a third slide 53, a fourth slide 54, a third drive mechanism 55, and a fourth drive mechanism 56. The third guide rail 51 is arranged on the base plate 1 along the X direction. The third slide 53 is slidably connected to the third guide rail 51.

The leveling mechanism 10 includes a fifth slide 101, a fifth guide rail 102, a sixth slide 103, a fifth drive mechanism 104, a sixth drive mechanism 105, and a second hydraulic cylinder 106. The fifth slide 101 is slidably connected to the third guide rail 51. The fifth drive mechanism 104 is disposed on the base plate 1 and is used to drive the fifth slide 101 to move along the third guide rail 51. The sixth slide 103 is slidably connected to the fifth guide rail 102 and arranged along the Y direction on the fifth slide 101. The sixth drive mechanism 105 is disposed on the fifth slide 101 and is used to drive the sixth slide 103 to move along the fifth guide rail 102. The second hydraulic cylinder 106 is disposed on the sixth slide 103 and is used to adjust the height difference between the front and rear ends of the machine base 200. The scale plate 11 is vertically disposed on the base plate 1 and is used to provide a reference for the alignment of the machine base 200.

[0047] Specifically, in conjunction with the appendix Figure 1 The fifth slide 101 is slidably connected to two third guide rails 51. A fifth drive mechanism 104 is provided on the base plate 1 to drive the fifth slide 101 to move along the third guide rails 51. Two fifth guide rails 102 are arranged at intervals on the upper surface of the fifth slide 101, wherein the extension direction of the fifth guide rails 102 is the Y direction, i.e., attached... Figure 1 In the Y-axis direction, the sixth slide 103 is slidably connected to two fifth guide rails 102. A sixth drive mechanism 105 is provided on the fifth slide 101 to drive the sixth slide 103 to move along the fifth guide rails 102. A second hydraulic cylinder 106 is installed on the sixth slide 103 to adjust the height difference between the front and rear ends of the machine base 200. The scale plate 11 is along the vertical direction (see attached). Figure 1 The Z-axis direction is set on the base plate 1 to provide a reference for the alignment of the base 200.

[0048] In this embodiment, a ruler plate 11 is provided on the tooling, and it cooperates with the second hydraulic cylinder 106. The ruler plate 11 is used to provide a precise alignment reference, and the second hydraulic cylinder 106 performs fine-tuning and alignment operations on the machine base 200 through precise hydraulic control. This cooperation method can achieve precise alignment of the square box motor base in a short time, greatly improving clamping efficiency and accuracy, and reducing the time and errors of repeated manual adjustments. The second hydraulic cylinder 106 can move along the X-axis and Y-axis respectively to accommodate machine bases 200 of different sizes.

[0049] Optionally, the positioning fixture for the square box motor base may also include a control panel. The control panel connects to the hydraulic and electrical control systems, serving functions such as operation control and data storage. The control panel's electrical control center has digital storage capabilities. During the positioning process of the first base 200, manual input of adjustment data is required. Subsequent square box motor bases of the same specification that have already been entered have a "one-click" data retrieval function, enabling rapid and accurate positioning of the second positioning mechanism 3, the third positioning mechanism 4, the fourth positioning mechanism 5, and the leveling mechanism 10. This function greatly simplifies the operation steps, reduces reliance on the operator's skill level and experience, effectively improves work efficiency, and significantly reduces the operator's labor intensity, improving the working environment and conditions.

[0050] Furthermore, the positioning fixture for square box motor bases can be modularly designed, dividing the fixture into multiple independently detachable and replaceable functional modules. This modular structure not only simplifies the manufacturing and maintenance process of the fixture but also significantly improves its versatility and adaptability. The innovative structural design allows the fixture to quickly switch between processing tasks for various specifications and models of square box motor bases without requiring large-scale modifications or redesigns, thereby effectively reducing production and time costs.

[0051] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

[0052] While the present invention has been disclosed above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the scope of protection of the present invention.
