Description

Technical Field

[0001] This utility model relates to the field of motor manufacturing technology, and in particular to a clamping mechanism. Background Technology

[0002] A segmented stator is formed by circumferentially splicing multiple segmented stators into a circle and then fixing them by welding or riveting to form a complete stator core. In the stator core and winding assembly stage, it is necessary to first complete the winding on each segmented stator and then assemble the wound segmented stators into a circle. However, when fixing the stator, only one stator can be clamped at a time, which is time-consuming, labor-intensive, and has low processing efficiency. Utility Model Content

[0003] The main purpose of this utility model is to propose a clamping mechanism that aims to solve the technical problem of low work efficiency when clamping workpieces one by one at a time.

[0004] To achieve the above objectives, the clamping mechanism proposed in this utility model includes:

[0005] A mounting base is provided with a plurality of processing positions along a first direction, the processing positions being used to place workpieces;

[0006] Several clamping plates are provided, with one clamping plate on each side of each processing station;

[0007] A push plate is slidably disposed on the mounting base. The push plate is drivenly connected to the clamping plate so that the clamping plate has a first state and a second state. In the first state, the push plate slides along a second direction, causing the clamping plate to move away from the processing position, so as to place the workpiece at the processing position or remove the workpiece from the processing position. In the second state, the clamping plate moves towards the processing position to abut against both sides of the workpiece.

[0008] In one embodiment, the push plate is provided with an inclined groove extending along a first direction. The clamping mechanism further includes a pin extending along the first direction, and a plurality of clamping plates are mounted on the pin. The pin is disposed in the groove. The push plate slides along a second direction, causing the pin to move along a third direction and driving the clamping plates closer to or away from the mounting base.

[0009] In one embodiment, the clamping plate includes a mounting plate and a pressing plate, the pressing plate being slidably connected to the mounting base, the pin passing through a plurality of the mounting plates in sequence, and the pressing plate being disposed at one end of the mounting plate for pressing the workpiece.

[0010] In one embodiment, the crimping plate is inclined from one end near the mounting plate to the end away from the mounting plate to form a downward-sloping crimping surface.

[0011] In one embodiment, slots are provided on both sides of the processing position, the slots extend along the third direction, and each mounting plate is slidably disposed in one of the slots.

[0012] In one embodiment, the mounting base has an open space on one side, the processing position is located on the top of the mounting base, the push plate is slidably disposed on the side of the open space, and the pin is disposed in the active space so that the pin and the clamping plate can be raised and lowered in the active space by sliding the push plate.

[0013] In one embodiment, the clamping mechanism further includes an elastic element disposed within the movable space, and the elastic element elastically connects the push plate and the sidewall of the movable space away from the opening.

[0014] In one embodiment, the side of the push plate is further provided with a limiting groove extending along the second direction, and the clamping mechanism further includes a slider, which is fixed to the side of the mounting base with the opening, and the slider is slidably connected to the limiting groove.

[0015] In one embodiment, the clamping mechanism further includes two handles, which are respectively located at both ends of the mounting base.

[0016] In the technical solution of this utility model, a processing position is set on the top of the mounting base, and a clamping plate is set on each side of the processing position. By moving the push plate on the mounting base along the second direction, the clamping plate slides on the mounting base, and the clamping plate has a first state and a second state. In the first state, the clamping plate rises and moves away from the processing position, and there is a certain gap between the clamping plate and the processing position. At this time, the workpiece is pushed from one side of the processing position and moved to the processing position. The push plate moves in the opposite direction along the second direction, driving the clamping plate to descend vertically on the mounting base. The clamping plate moves closer to the processing position, so that the clamping plate and the processing position cooperate to clamp the workpiece. Since multiple processing positions are set at intervals along the length direction on the mounting base, each position is equipped with a clamping plate, and each position can place a workpiece. By sliding the push plate, the clamping plates can move simultaneously to clamp and fix multiple workpieces at the same time, thereby improving processing efficiency. Attached Figure Description

[0036] A segmented stator is formed by circumferentially splicing multiple segmented stators into a circle and then fixing them by welding or riveting to form a complete stator core. In the stator core and winding assembly stage, it is necessary to first complete the winding on each segmented stator and then assemble the wound segmented stators into a circle. However, when fixing the stator, only one stator can be clamped at a time, which is time-consuming, labor-intensive, and has low processing efficiency.

[0037] This utility model proposes a clamping mechanism.

[0038] Please see Figure 1 and Figure 2In one embodiment of this utility model, the clamping mechanism includes a mounting base 100, a clamping plate 200, and a push plate 300. The mounting base 100 has multiple processing positions 102 arranged along a first direction, each processing position 102 used to place a workpiece 10. Each processing position 102 has a clamping plate 200 on both sides. The push plate 300 is slidably disposed on the mounting base 100, and the push plate 300 is drivenly connected to the clamping plate 200 to allow the clamping plate 200 to have a first state and a second state. In the first state, the push plate 300 slides along the second direction, causing the clamping plate 200 to move away from the processing position 102, so as to place the workpiece 10 on the processing position 102 or remove the workpiece 10 from the processing position 102. In the second state, the clamping plate 200 moves towards the processing position 102 to abut against both sides of the workpiece 10.

[0039] In the technical solution of this utility model, a processing position 102 is provided on the top of the mounting base 100, and a clamping plate 200 is provided on each side of the processing position 102. A push plate 300 moves along a second direction on the mounting base 100, causing the clamping plate 200 to slide on the mounting base 100, resulting in a first state and a second state for the clamping plate 200. In the first state, the clamping plate 200 rises and moves away from the processing position 102, with a certain gap between the clamping plate 200 and the processing position 102. At this time, the workpiece 10 is pushed from one side of the processing position 102, moving it to the processing position. At station 102, push plate 300 moves in the opposite direction along the second direction, causing clamping plate 200 to descend vertically on mounting base 100. Clamping plate 200 approaches processing station 102, so that clamping plate 200 and processing station 102 cooperate to clamp workpiece 10. Since multiple processing stations 102 are spaced apart along the length direction on mounting base 100, each station is equipped with clamping plate 200, and workpiece 10 can be placed on each station. By sliding push plate 300, clamping plate 200 can move simultaneously to clamp and fix multiple workpieces 10 at the same time, thereby improving processing efficiency.

[0040] Specifically, the mounting base 100 extends along the first direction. The shape and material of the mounting base 100 are not limited. In this embodiment, the mounting base 100 includes an upper body 130 and a lower body 140. The upper body 130 is located above the lower body 140. Multiple processing positions 102 are spaced apart along the first direction on the top of the upper body 130. The processing positions 102 are used to place the workpiece 10. In this embodiment, the workpiece 10 is a segmented stator. The following description takes a segmented stator as an example. Since clamping plates 200 are respectively provided on both sides of each processing position 102, that is, the clamping plates 200 are also spaced apart along the first direction, the push plate 300 extends along the first direction and can simultaneously drive multiple clamping plates 200 to move in the vertical direction, so that multiple clamping plates 200 rise and fall simultaneously to clamp the workpiece 10 on the processing position 102, or release the workpiece 10.

[0041] In one embodiment, such as Figure 6 As shown, since the bottom of the segmented stator has a bottom groove, a protruding edge 150 is provided on the processing position 102. When the clamping plate 200 is in the first state, the bottom groove of the segmented stator is aligned with the protruding edge 150, and the segmented stator is pushed in the second direction to enter the processing position 102. The protruding edge 150 facilitates the rapid placement of the segmented stator into the processing position 102 and can guide the movement of the segmented stator.

[0042] In one embodiment, such as Figure 4 and Figure 5 As shown, a limiting block 120 is provided on the upper body 130. Each processing position 102 is provided with a corresponding limiting block 120. The limiting block 120 is located at one end of the processing position 102. When the segmented stator is pushed into the processing position 102 along the second direction, the limiting block 120 abuts against the segmented stator to prevent the segmented stator from moving continuously and leaving the processing position 102.

[0043] In an embodiment of this utility model, the push plate 300 is provided with an inclined slide groove 310, the slide groove 310 extends along a first direction, the clamping mechanism further includes a pin 400, the pin 400 extends along the first direction, and a plurality of clamping plates 200 are installed on the pin 400. The pin 400 is slidably disposed in the slide groove 310. The push plate 300 slides along the second direction, causing the pin 400 to move along a third direction, and driving the clamping plates 200 to move closer to or away from the mounting base 100.

[0044] Specifically, please refer to Figure 2 In the third direction, which is vertical, the push plate 300 is provided with a slide groove 310 extending along its length. The slide groove 310 is inclined when viewed from its cross-section, with the end furthest from the mounting base 100 higher than the end closest to the mounting base 100. The pin 400 is slidably disposed within the slide grooves 310 at both ends. Multiple clamping plates 200 pass through the middle of the pin 400, making the clamping plates 200 and the pin 400 an integral structure. When the push plate 300 is pushed towards the mounting base 100 in the second direction, the contact point between the slide groove 310 and the pin 400 gradually increases, thereby causing the pin 400 to gradually rise, thus driving... As the clamping plate 200 rises, the gap between the clamping plate 200 and the processing position 102 increases. The segmented stator is pushed from one end of the processing position 102 by a force in the same direction as the push plate 300, pushing the segmented stator onto the processing position 102. In the opposite direction, the push plate 300 is pushed away from the mounting base 100. At this time, the position of the pin 400 in the slide groove 310 gradually decreases at the contact point with the slide groove 310, thereby driving the pin 400 and the clamping plate 200 to descend. The descent of the clamping plate 200 cooperates with the processing position 102 to clamp the workpiece 10 for subsequent winding processing.

[0045] In one embodiment, a linear drive structure (not shown) such as a cylinder or hydraulic cylinder is provided and driven to the push plate 300 to move the push plate 300 toward or away from the mounting base 100, thereby automating the movement process and improving processing efficiency.

[0046] In an embodiment of this utility model, the clamping plate 200 includes a mounting plate 210 and a pressing plate 220. The pressing plate 220 is slidably connected to the mounting base 100. The pin 400 passes through a plurality of mounting plates 210 in sequence. The pressing plate 220 is disposed at one end of the mounting plate 210 for pressing the workpiece 10.

[0047] Please refer to Figure 2 Specifically, the clamping plate 200 includes a pressing plate 220 and a mounting plate 210 arranged sequentially from top to bottom. The mounting plate 210 extends vertically, and a pin 400 sequentially connects multiple mounting plates 210 along a first direction. The pressing plate is located on top of the mounting plate 210. The pin 400 raises and lowers, causing the mounting plate 210 and the pressing plate 220 to rise and fall. The cross-sectional area of ​​the pressing plate 220 is larger than the area of ​​the mounting plate 210, that is, the distance between two mounting plates 210 on both sides of the processing position 102 is smaller than the distance between two pressing plates 220. When the clamping plate 200 rises, the pressing plate 220 moves away from the processing position 102. The workpiece 10 is placed on the processing position 102 and located between two mounting plates 210. At this time, the workpiece 10 is in an interactive state between the two mounting plates 210. When the clamping plate 200 moves downward, the pressing plate 220 descends. The end of the pressing plate 220 near the mounting plate 210 abuts against the upper surface of the workpiece 10, and the pressing plates 220 on both sides of the workpiece 10 abut against the two sides of the workpiece 10 respectively, so as to form a clamping of the workpiece 10 and prevent the workpiece 10 from moving during processing. Since the pin 400 connects multiple mounting plates 210, the simultaneous lifting and lowering of multiple pressing plates 220 can clamp and fix multiple workpieces 10 at the same time.

[0048] In one embodiment, please refer to Figure 2 The pressing plate 220 is inclined from one end near the mounting plate 210 to the end away from the mounting plate 210 to form a pressing surface with the inclined surface facing downward. In this embodiment, the workpiece 10 is a segmented stator. Since the segmented stator is spliced ​​into a circle along the circumference, when the segmented stator is placed on the processing position 102, the bottom is an arc-shaped structure and the two sides are upward inclined surfaces, which are exactly matched with the inclined surface of the pressing plate 220. When the pressing plate 220 descends, the inclined surface of the pressing plate 220 abuts against the inclined surface of the segmented stator to complete the clamping of the segmented stator.

[0049] In one embodiment, a clamping plate 200 is provided between any two adjacent processing positions 102, that is, there is a processing position 102 on each side of the clamping plate 200, and the two sides of the bottom of the pressing plate 220 are inclined surfaces, so as to press and clamp the segmented stators on the processing positions 102 on both sides. This not only allows multiple workpieces 10 to be clamped at the same time, but also saves the manufacturing cost of the clamping plate 200.

[0050] Please refer to Figure 6 In an embodiment of this utility model, slots 101 are respectively provided on both sides of the processing position 102. The slots 101 extend along the third direction, and each mounting plate 210 is correspondingly slidably disposed in one of the slots 101.

[0051] Specifically, the slot 101 is set on the upper body 130 and extends vertically. The mounting plate 210 is inside the slot 101, and the pressing plate 220 is above the slot 101. When the sliding push plate 300 is slidable, the mounting plate 210 moves up and down inside the slot 101. The setting of the slot 101 can prevent the pressing plate 220 from moving and deviating, which would affect the clamping of the workpiece 10.

[0052] In an embodiment of this utility model, the mounting base 100 has an active space with an opening on one side, the processing position 102 is disposed on the top of the mounting base 100, the push plate 300 is slidably disposed on the side of the active space with the opening, and the pin 400 is disposed in the active space so that the pin 400 and the clamping plate 200 can be raised and lowered in the active space by sliding the push plate 300.

[0053] Please refer to Figure 3 The lower body 140 has an opening on one side and an open top. The upper body 130 is installed above the lower body 140. The mounting plate 210 is inserted downward into the movable space from the slot 101. The push plate 300 is on the side of the lower body 140 with an opening, and the slide 310 is located on the side of the push plate 300 facing the movable space. It moves toward or away from the movable space so that the clamping plate 200 rises or falls in the slot 101. The movable space also provides movement space for the push plate 300 to slide, making the clamping more precise.

[0054] Please refer to Figure 3 and Figure 5In an embodiment of this utility model, the clamping mechanism further includes an elastic element 500. The elastic element 500 is disposed within the movable space and elastically connects the push plate 300 and the side wall of the movable space away from the opening. By pushing the push plate 300 along the second direction, the clamping plate 200 is raised to a first state, and the workpiece 10 is placed in the processing position 102. Since the elastic element 500 is in a compressed state when the push plate 300 is pushed, after the push plate 300 is released, the elastic element 500 rebounds, pushing the push plate 300 to move along the second direction away from the mounting base 100, thereby causing the clamping plate 200 to descend to clamp all the workpieces 10 on the mounting base 100. The setting of the elastic element 500 can make the entire clamping process smoother and more automated.

[0055] In one embodiment, the elastic element 500 may be a return spring, and there is no limitation on this.

[0056] Please refer to Figure 3 and Figure 4 In an embodiment of this utility model, the side of the push plate 300 is also provided with a limiting groove 320 extending along the second direction. The clamping mechanism also includes a slider 110. The slider 110 is fixed to the side of the mounting base 100 where the opening is provided, and the slider 110 is slidably connected to the limiting groove 320. The slider 110 is engaged in the limiting groove 320. Whether the push plate 300 is pushed towards the mounting base 100 along the second direction, or the push plate 300 is pushed away from the mounting base 100, the slider 110 slides in the limiting groove 320, making the movement of the push plate 300 along the second direction more precise and faster.

[0057] In one embodiment, a limiting groove 320 is provided at both ends of the push plate along the length direction, and a slider 110 is also provided at both ends of the side of the mounting plate with an opening along the length direction. Each slider 110 is slidably connected to a limiting groove 320.

[0058] Please refer to Figure 1 In an embodiment of this utility model, the clamping mechanism further includes two handles 600, which are respectively located at both ends of the mounting base 100. The handles 600 are mounted on the mounting base 100 by screws, which facilitates the handling and transfer of the clamping mechanism to adjust it to a suitable position and improve processing efficiency.

[0059] The above description is merely an exemplary embodiment of the present utility model and does not limit the scope of protection of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present utility model.
