[0067] The application will be further explained in combination with the specific implementation manners.

[0068] As shown in Figure 1 The winding pressing mechanism provided by the embodiment comprises a supporting structure 1 and a pressing structure 2.

[0069] The supporting structure 1 comprises a cross frame 11.

[0070] The pressing structure 2 is arranged on the cross frame 11 and can move along the axial direction of the cross frame 11.

[0071] The pressing structure 2 comprises a structure device 21, a horizontal moving device 22 and a working device 23.

[0072] As shown in Figures 2-3 The structure device 21 comprises a sliding frame 211, a back plate 212 and a fixed frame 213.

[0073] The back plate 212 is a vertically arranged plate body, one end of the back plate 212 close to the cross frame 11 is provided with the sliding frame 211, and the other end of the back plate 212 away from the cross frame 11 is provided with the fixed frame 213.

[0074] The sliding frame 211 is an L-shaped plate body, and the lower end surface of the sliding frame 211 is in sliding connection with the upper end surface of the cross frame 11.

[0075] The fixed frame 213 is an L-shaped plate body, and the working device 23 is arranged on the fixed frame 213.

[0076] The working device 23 is used for pressing the winding into the iron core.

[0077] The horizontal moving device 22 is used for controlling the horizontal movement of the pressing structure 2 along the axial direction of the cross frame 11.

[0078] As shown in Figure 2 The horizontal moving device 22 comprises a speed reducer 221 and a gear 222.

[0079] The speed reducer 221 is arranged on the side of the back plate 212 away from the cross frame 11.

[0080] The back plate 212 is provided with a first through hole 3, and the speed reducer 221 and the gear 222 are arranged on the two sides of the first through hole 3, respectively.

[0081] The gear 222 is driven by the reduction motor 221 through a connecting shaft passing through the first through hole 3;

[0082] like Figures 2-3 As shown, the working device 23 includes an electric cylinder 231, a mounting plate 232, and a pressure head 233;

[0083] The fixing frame 213 is provided with a second through hole (not shown in the figure).

[0084] The electric cylinder 231 is mounted on the fixed frame 213 and passes through the second through hole to be fixedly connected to the mounting plate 232;

[0085] A pressure head 233 is detachably provided on the side of the mounting plate 232 away from the electric cylinder 231;

[0086] The pressure head 233 is used to press the winding into the interior of the iron core and can be replaced according to the actual working conditions.

[0087] In actual operation, the winding pressing mechanism disclosed in this application adjusts the position of the pressing structure 2 via the lateral movement device 22 so that the pressing head 233 is positioned directly above the pressing station. The pressing station is equipped with an iron core and windings. The pressing head 233 is detachably mounted on the mounting plate 232, and its model should match the iron core and windings, and can be replaced according to task requirements. The electric cylinder 231 is activated, causing the mounting plate 232 and the pressing head 233 to move downwards, bringing the pressing head 233 into contact with the windings. The electric cylinder 231 continues to push the pressing head 233 downwards until it presses the windings into the stator inside the iron core. Subsequently, the electric cylinder 231 reverses its movement, raising the pressing head 233 to its initial position. At this point, a robotic arm in a subsequent process removes the stator from the station and places the next set of windings and iron cores on the station. After the electric cylinder 231 drives the pressing head 233 to rise, the transverse moving device 22 drives the pressing structure 2 to move above the next station and the electric cylinder 231 pushes the pressing head 233 to complete the pressing work. This cycle makes the pressing structure 2 move back and forth on the crossbeam 11 to complete the pressing work, realizing automated continuous production.

[0088] like Figures 1-2 As shown, as a further embodiment of this application, a rack 111 is fixedly provided along the axial direction on the side of the cross frame 11 near the press-in structure 2.

[0089] The rack 111 is coupled to the gear 222;

[0090] After the gear motor 221 drives the gear 222 to rotate, the gear 222, through its coupling connection with the rack 111, causes the press-in structure 2 to move horizontally along the axial direction of the cross frame 11.

[0091] In actual work, the deceleration motor 221 is turned on to drive the gear 222 to rotate, the rack 111 engaged with the gear 222 and fixedly arranged on the cross frame 11 provides a reaction force for the gear 222, so that the gear 222 moves on the rack 111, and in turn drives the pressing structure 2 to move horizontally along the axis direction of the cross frame 11.

[0092] As shown in Figure 1 As a further embodiment of the present application, the lower end of the sliding frame 211 is provided with a first sliding block 41;

[0093] The upper end surface of the cross frame 11 is provided with a first sliding rail 42 parallel to the axis direction of the cross frame 11;

[0094] The first sliding block 41 and the first sliding rail 42 cooperate with each other to guide and limit the movement of the pressing structure 2 along the axis direction of the cross frame 11, and provide vertical support force for the pressing structure 2.

[0095] As a further embodiment of the present application, the back plate 212 is further provided with a second sliding block 43;

[0096] The side wall of the cross frame 11 is provided with a second sliding rail 44 parallel to the axis direction of the cross frame 11;

[0097] The second sliding block 43 and the second sliding rail 44 cooperate with each other to guide and limit the movement of the pressing structure 2 along the axis direction of the cross frame 11, and provide horizontal support force for the pressing structure 2.

[0098] In actual work, in order to strengthen the guiding and limiting effect of the pressing structure 2 during movement on the cross frame 11, the first sliding block 41 and the second sliding block 43 are arranged at the lower end of the sliding frame 211 and on the back plate 212 respectively, and the first sliding rail 42 and the second sliding rail 44 are arranged on the corresponding regions of the cross frame 11. In addition to the guiding and limiting function, the above structure can also provide support function. Since the pressing structure 2 is arranged on the cross frame 11, its vertical support force is provided by the front surface of the first sliding block 41, the side surface of the second sliding block 43 and the gear 222, and in the horizontal direction, since the pressing structure 2 is arranged on one side of the cross frame 11, the pressing structure 2 will generate a moment tending to move in the direction of the cross frame 11, and the second sliding block 43 provides corresponding support force.

[0099] As shown in Figures 2-3 As a further embodiment of the present application, the working device 23 further comprises a guide shaft 45;

[0100] The fixing frame 213 is provided with a third through hole (not shown in the figure).

[0101] The lower end of the guide shaft 45 is disposed on the mounting plate 232, and the upper end passes through the third through hole, which serves to guide and limit the up and down movement of the mounting plate 232 and the pressure head 233.

[0102] As a further embodiment of this application, the guide shaft 45 is provided in multiple forms, preferably four;

[0103] Limiting plates 51 are provided between the guide shafts 45 to prevent the pressure head 233 from falling too far due to operational errors or malfunctions of the electric cylinder 231, which could damage the winding and the iron core.

[0104] like Figure 1 As shown, as a further embodiment of this application, limit blocks 52 are provided at both ends of the cross frame 11 to prevent the pressing structure 2 from leaving the working area due to operational errors or failure of the reduction motor 221.

[0105] In actual operation, the winding pressing mechanism disclosed in this application, during the up-and-down movement of the pressing head 233 driven by the electric cylinder 231, can guide and limit the mounting plate 232 and the pressing head 233 through multiple guide shafts 45 to prevent positional deviation during their up-and-down movement. Furthermore, a limiting plate 51 is further provided at the top of the pressing head 233. If an operational error or a malfunction of the electric cylinder 231 causes the pressing head 233 to descend too far, the limiting plate 51 will abut against the fixed frame 213 to prevent the mounting plate 232 from continuing to move downwards, thereby preventing damage caused by the pressing head 233 continuing to move downwards. When the pressing structure 2 moves laterally, to avoid the potential danger of the pressing structure 2 leaving its working range due to operational errors or a malfunction of the reduction motor 221, limiting blocks 52 are provided on the crossbeams 11 on both sides of the working range of the pressing structure 2.

[0106] like Figure 1 As shown, as a further embodiment of this application, the support structure 1 includes a support base 12;

[0107] The support base 12 is located below the cross frame 11 and is used to support the cross frame 11.

[0108] like Figures 2-3 As shown, as a further embodiment of this application, the sides of both the sliding frame 211 and the fixed frame 213 are provided with triangular support plates 6, which are used to provide greater structural support for the sliding frame 211 and the fixed frame 213.

[0109] likeFigure 1 As further embodiments of the present application, the speed-reducing motor 221 and the electric cylinder 231 are powered by a drag chain cable 7, as shown.

[0110] The winding pressing mechanism disclosed in the application adjusts the position of the pressing structure 2 so that the pressing head 233 is located directly above the pressing station during actual operation, specifically, the deceleration motor 221 is turned on and drives the gear 222 to rotate, the rack 111 engaged with the gear 222 and fixedly arranged on the cross frame 11 provides a reaction force for the gear 222, so that the gear 222 moves on the rack 111, thereby driving the pressing structure 2 to move horizontally along the axis direction of the cross frame 11. In order to strengthen the guiding and limiting effect of the pressing structure 2 during movement on the cross frame 11, a first sliding block 41 and a second sliding block 43 are arranged at the lower end of the sliding frame 211 and the back plate 212 respectively, and a first sliding rail 42 and a second sliding rail 44 are arranged on the corresponding regions of the cross frame 11. In addition to the guiding and limiting function, the above structure can also provide support function. Since the pressing structure 2 is arranged on the cross frame 11, the support force in the vertical direction is provided by the first sliding block 41 front, the second sliding block 43 side and the gear 222, and in the horizontal direction, since the pressing structure 2 is arranged on one side of the cross frame 11, the pressing structure 2 will generate a moment deviated to the direction of the cross frame 11, and the second sliding block 43 provides a corresponding support force. The pressing station is provided with an iron core and a winding, the pressing head 233 is detachably arranged on the mounting plate 232, the model thereof should match the iron core and the winding, and can be replaced according to the task requirement. Turn on the electric cylinder 231, the electric cylinder 231 drives the mounting plate 232 and the pressing head 233 to move downward, the pressing head 233 descends to contact the winding. The electric cylinder 231 continues to push the pressing head 233 downward until the pressing head 233 presses the winding into the iron core to form an internal stator. Then the electric cylinder 231 reverses to lift the pressing head 233 to the initial position. During the upward and downward movement of the pressing head 233 driven by the electric cylinder 231, the mounting plate 232 and the pressing head 233 are guided and limited by the plurality of guide shafts 45, so as to avoid position deviation during upward and downward movement. In addition, a limiting plate 51 is further arranged on the top of the pressing head 233, when the pressing head 233 descends too far due to operation failure or electric cylinder 231 failure, the limiting plate 51 abuts against the fixed frame 213 to prevent the mounting plate 232 from continuing to move downward, thereby preventing the pressing head 233 from continuing to move downward and causing damage. At this time, the mechanical arm of the subsequent process takes away the stator on the station and places the next group of windings and iron cores on the station. After the electric cylinder 231 drives the pressing head 233 to lift, the cross moving device 22 drives the pressing structure 2 to move above the next station and the electric cylinder 231 pushes the pressing head 233 to complete the pressing work, so as to realize the automatic continuous production by the reciprocating movement of the pressing structure 2 on the cross frame 11.When the pressing structure 2 moves laterally, to avoid the risk of the pressing structure 2 leaving its working range due to operation errors or failure of the reduction motor 221, limit blocks 52 are arranged on the lateral frames 11 on both sides of the working range of the pressing structure 2.

[0111] With the above technical solutions, the present application has the following beneficial effects:

[0112] (1) Through the cooperative work of the lateral moving device 22 and the electric cylinder 231, automatic reciprocating movement and precise pressing operation of the pressing structure 2 on the lateral frame 11 are realized, greatly improving the automation level of the production line, reducing manual intervention, and thus improving the production efficiency.

[0113] (2) By arranging sliding blocks on the lower end of the sliding frame 211 and the back plate 212 and corresponding sliding rails on the lateral frame 11, not only effective guiding and limiting functions are provided, but also the support stability of the pressing structure 2 during movement is enhanced, ensuring the accuracy and safety of the pressing operation.

[0114] (3) The pressing head 233 is detachably arranged on the mounting plate 232, and the model can be replaced according to the specific needs of the core and winding, which makes the technical solution flexible to adapt to different specifications and types of stator production needs, improving the versatility and flexibility of the production line.

[0115] (4) By arranging the guide shaft 45 to guide and limit the mounting plate 232 and the pressing head 233, position deviation during up and down movement is avoided; at the same time, a limit plate 51 is arranged on the top of the pressing head 233 to prevent excessive downward movement due to operation errors or electric cylinder 231 failure, further ensuring the safety of the equipment and products.

[0116] (5) After the pressing structure 2 completes a pressing operation, it can automatically move to the next station and realize rapid replacement of the station through the mechanical arm, optimizing the production process, reducing waiting time, and improving overall production efficiency.

[0117] (6) By arranging limit blocks 52 on the lateral frames 11 on both sides of the working range of the pressing structure 2, the risk of the pressing structure 2 leaving the working range due to operation errors or failure of the reduction motor 221 is effectively avoided, further improving the stability and reliability of the production line.

[0118] Embodiment 2

The floating support table 830 is provided with a support surface on the side close to the part to be pressed 81, and the inner side end of the split pressure head 821 abuts against the support surface.

[0121] In use, the outer side end of the split pressure head 821 abuts against the end surface of the part to be pressed 81, and the dimensional tolerance on the end surface of the part to be pressed 81 forces the plurality of split pressure heads 821 to move in error between each other, and the floating support table 830 is thereby pivoted relative to the main body 810, and the dimensional tolerance compensation of the plurality of split pressure heads 821 to the part to be pressed is achieved.

[0122] In the present application, the plurality of split pressure heads 821 can move in error in the axial direction and within the tolerance range according to the dimensional tolerance on the end surface of the part to be pressed 81, and the floating support table 830 is also slightly pivoted, until all the split pressure heads 821 are completely and tightly abutted against the end surface of the part to be pressed 81, thereby achieving the compensation of the dimensional tolerance of the part to be pressed 81. The present application avoids the suspension of the pressure head in the prior art due to the tolerance, and the part to be pressed 81 is pressed to be deviated or inclined during the pressing process.

[0123] The plurality of split pressure heads 821 are uniformly arranged in the circumferential direction. Alternatively, the plurality of split pressure heads 821 are of different sizes and are arranged according to the shape of the part to be pressed 81.

[0124] In the present application, the axial direction is the direction of the pressure applied to the split pressure head pair 820, and the main body 810 is usually in the shape of a cylinder or a circular column, and the above-mentioned axial direction is equivalent to the axial direction of the main body 810.

The lengths of the plurality of split pressure heads 821 in the axial direction are different, so as to adapt to the outer shape structure of the part to be pressed 81.

[0130] The floating support platform 830 is provided with a plurality of support arms 831, which are arranged one by one corresponding to the split pressure heads 821. As a preferred embodiment of the present application, in the circumferential direction, the support arms 831 are arranged at the central positions of the corresponding split pressure heads 821. Thus, the balance of force is better achieved.

[0131] As a preferred embodiment of the present application, the support arms 831 are arranged obliquely to one side of the split pressure heads 821, and the end face of the support arms 831 in contact with the split pressure heads 821 is an outward convex arc face.

[0138] like Figure 9 As shown, this embodiment also includes an outer sleeve 850, which is fitted onto the outside of the shaft portion 842, forming an annular limiting cavity between the outer sleeve 850 and the shaft portion 842. The pressure dividing head 821 is slidably disposed within the annular limiting cavity along the axial direction. The annular limiting cavity is used to limit the radial displacement of the pressure dividing head 821 on the shaft portion 842. The inner portion of the outer sleeve 850 is fitted onto the sleeve portion 841, covering the opening 844 and the support arm 831.

[0139] The fit between the inner circular surface of the inner side of the outer sleeve 850 and the outer circular surface of the sleeve portion 841 meets the positioning requirements, thereby achieving the radial positioning requirements of the outer sleeve 850. This, in turn, ensures the positioning accuracy, such as the coaxiality of the annular limiting cavity and the pressure dividing head 821.

[0140] As a further embodiment of this application, it also includes a fastening bolt 851, and through holes are provided radially on the outer sleeve 850 and the shaft body 842. After the fastening bolt 851 passes through the through holes on the outer sleeve 850 and the shaft body 842, the outer sleeve 850 and the shaft body 840 are inherently connected.

[0141] Furthermore, a portion of the pressure dividing head 821 is provided with an elongated hole 822 through which the fastening bolt 851 passes. The pressure dividing head 821 can slide relative to the fastening bolt 851 along the axial direction and within the range of the elongated hole 822.

[0142] As a further embodiment of this application, the shaft portion 842 is a positioning shaft, that is, the coaxiality and outer diameter tolerance of the shaft portion 842 meet the positioning design requirements.

[0143] like Figure 4 and 5 As shown, it also includes a mounting base 860 for connecting to the stamping head of the stamping equipment; the mounting base 860 is provided with mounting holes, and the main body 810 is detachably inserted into the mounting holes.

[0144] In a preferred embodiment of this application, the main body 810 is inserted into the mounting hole and then locked in place by fastening screws 861.

[0145] The application can automatically adjust the relative positions of each pressure head 821 according to the size tolerance of the pressed end face of the to-be-pressed part, thereby realizing automatic compensation of the size tolerance, and thereby making the stress of the to-be-pressed part more uniform in the circumferential direction during pressing, avoiding being pressed off-center and inclined, and ensuring assembly quality and precision.

[0146] By adopting the technical scheme, the application has the following beneficial effects:

[0147] (1) By the displacement of the pressure head and the swing of the floating support table, the size tolerance of the to-be-pressed part can be automatically compensated, ensuring the accuracy during pressing.

[0148] (2) The pressure head can be adjusted according to the shape and size of the to-be-pressed part, so that the pressing equipment can adapt to parts of various specifications.

[0149] (3) By the displacement of the pressure head and the swing of the floating support table, the risk of the part being pressed off-center or inclined during pressing is reduced.

[0150] (4) The spherical or arc surface design of the floating support table and the adaptive structure with the main body provide flexible swing capability, enhancing the stability and durability of the equipment.

[0151] (5) The design and layout of the support arm help to achieve force balance, further improving the uniformity and accuracy during pressing.

[0152] (6) The design of the outer sleeve and the shaft sleeve body ensures the coaxiality and positioning accuracy of the pressure head, thereby improving the overall pressing quality.

[0153] (7) The ability to automatically compensate for size tolerance reduces the need for manual adjustment, improves production efficiency, and reduces production costs.
