Description

Technical Field

[0001] This utility model belongs to the field of stator processing technology, and specifically relates to a flipping finishing machine. Background Technology

[0002] After the motor stator coils are wound, the entire stator coil needs to be shaped to its specifications and dimensions to make the stator more durable. A stator finishing machine is a mechanical device that automates the shaping of small and medium-sized stator coils, achieving the required dimensions in a single process.

[0003] According to the patent application number CN200610097555.8, a stator finishing machine is provided on its frame, with upper and lower hydraulic cylinders connecting the upper and lower moving plates of the upper and lower modules. The upper and lower moving plates are both mounted on guide columns on the frame. Protective tooth devices are provided on the opposite surfaces of the upper and lower modules. Movable push rods are installed on the guide columns corresponding to the protective tooth devices of the upper and lower modules. Movable plate positioning blocks are provided on the upper and lower modules at the connection points between the movable push rods and the movable plate of the protective teeth.

[0004] The operation process of the aforementioned stator finishing machine is as follows: the operator needs to install the stator with embedded coils on the lower mold, align the upper and lower modules, and then shape the stator through the upper and lower molds. After shaping, the operator removes and replaces the stator with a new one to be shaped. The problems with this patent are: the stator needs to be installed and adjusted manually by the operator, which can easily cause dimensional differences in the shaped stator, thus affecting the stator quality. Furthermore, the operator's mechanical and repetitive installation and replacement of the stator is not only inefficient but also increases additional labor costs during production. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a flipping finishing machine.

[0006] The purpose of this utility model can be achieved through the following technical solution: a flip finishing machine, including a frame body, an upper mold mechanism and a lower mold mechanism; the frame body includes a frame base and a frame frame, a lower base plate is installed on the top of the frame base, the frame frame is installed on the rear half of the lower base plate, the top of the frame frame is an upper top plate, the upper mold mechanism is suspended in the upper part of the frame frame, and the lower mold mechanism is mainly installed on the lower base plate of the frame base;

[0007] The upper mold mechanism and the lower mold mechanism are arranged correspondingly. The upper mold mechanism includes, from top to bottom, a telescopic cylinder, an upper movable plate, and a shaping structure. The telescopic cylinder is vertically fixed on the upper top plate, and its central telescopic rod passes through the upper top plate and is fixedly connected to the upper movable plate, so that the telescopic cylinder can control the upper movable plate to move up and down. The bottom of the upper movable plate is equipped with a shaping structure through an upper pad. The lower mold mechanism includes a flipping pad, and a shaping structure is installed on one side of the flipping pad. A flipping piston that controls the flipping pad to flip is connected to its back side. An adjustment seat is provided on the lower bottom plate on the front side of the shaping structure of the lower mold mechanism.

[0008] The shaping structure achieves stator finishing through the expansion of the inner core and the contraction of the outer cavity. The inner core mainly includes a stretching rod and several expansion blocks forming a ring. The outer cavity mainly includes a sloping top rod, a downward positioning block, and a downward connecting block. The top of the stretching rod is fixedly connected to the upper movable plate or flipping pad, and the bottom forms a conical head. The expansion blocks are all installed within the annular expansion block ring. As the conical head of the stretching rod gradually sinks within the expansion block ring, the expansion blocks expand outward to shape the inner coil of the stator coil. The downward positioning block and the downward connecting block are spaced apart to form a ring structure. Each end of the downward positioning block has a top rod groove on its outer side wall. The top of the sloping top rod is fixedly connected to the upper pad or flipping pad, and the bottom extends into the top rod groove, contracting in conjunction with the downward positioning block to shape the outer coil of the stator coil.

[0009] In the aforementioned flipping finishing machine, the telescopic rod of the telescopic cylinder is fixedly connected to the upper fixed seat via a joint. The upper fixed seat has several connecting rods circumferentially inserted near its edge, and the bottom of the connecting rods is fixedly connected to the upper movable plate, thereby linking the telescopic cylinder with the upper movable plate.

[0010] In the aforementioned flipping finishing machine, the flipping piston is disposed inside the machine frame base and installed obliquely toward the flipping pad. A piston hole is provided on the rear side of the flipping pad on the lower base plate. The piston rod of the flipping piston passes through the piston hole and is movably connected to the back side of the flipping pad, so that the flipping piston can control the flipping pad to perform rotational flipping motion.

[0011] In the aforementioned flipping finishing machine, the front side of the shaping structure is provided with positioning posts on both the left and right sides perpendicular to it, and an arc-shaped stator bracket for supporting the stator is extended at the bottom.

[0012] In the aforementioned flipping finishing machine, the adjusting seat includes a rotating plate disposed at both the front and rear ends and several transmission shafts connected to the top of the rotating plate. The top of the rotating plate is arc-shaped, and its top height and arc angle are consistent with those of the stator bracket.

[0013] In the aforementioned flipping finishing machine, the expansion rod is fitted with a limiting seat on the upper side of the conical head by a fixing nut, and the top of the limiting seat is fixedly connected to the upper pad or the flipping pad.

[0014] In the aforementioned flipping finishing machine, in order to protect the inner core and outer cavity in the shaping structure, the shaping structure is provided with a fixing cover on the outside of the expansion block, the lower positioning block and the lower connecting block. The fixing cover is fixedly connected to the upper pad or the flipping pad by fixing screws. The bottom of the fixing cover is connected to the bottom of the lower positioning block and the lower connecting block with a fixing plate.

[0015] Compared with the prior art, the flipping finishing machine provided by this utility model can efficiently and quickly achieve the finishing of stator coils by expanding the inner core and contracting the outer cavity of the forming structure. By setting the upper mold mechanism and the lower mold mechanism accordingly, and setting the flipping pad and flipping piston on the lower mold mechanism, the stator can be transferred to the adjustment seat after finishing, which makes the installation and replacement of the stator convenient. It also eliminates the step of manually adjusting the upper and lower molds by the operator, improves the processing efficiency, ensures the processing quality, and reduces the production cost.

[0022] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0023] like Figures 1 to 4 As shown, this flipping finishing machine includes a frame body 100, an upper mold mechanism 200, and a lower mold mechanism 300. The frame body 100 includes a frame base 110 and a frame frame. A lower base plate 111 is installed on the top of the frame base 110. The frame frame 120 is installed on the rear half of the lower base plate 111. The top of the frame frame 120 is an upper top plate 121. The upper mold mechanism 200 and the lower mold mechanism 300 are correspondingly arranged. The upper mold mechanism 200 is suspended above the frame frame 120. The lower mold mechanism 300 is mainly installed on the lower base plate 111 of the frame base 110.

[0024] like Figure 2 As shown, the upper mold mechanism 200 includes, from top to bottom, a telescopic cylinder 210, an upper movable plate 220, and a shaping structure 400. The telescopic cylinder 210 is vertically fixed to the upper top plate 121 of the frame 120 to achieve reciprocating motion. The telescopic rod at the center of the telescopic cylinder 210 passes through the upper top plate 121 and is fixedly connected to the upper movable plate 220 through a connecting structure. The connecting structure includes a fixed seat joint at the end of the telescopic rod of the telescopic cylinder 210. The joint is engaged in the connecting seat slot at the top of the upper fixed seat 211. Several connecting rods 212 are circumferentially inserted on the outer side of the upper fixed seat near the edge of the connecting seat. The bottom of the connecting rods 212 is fixedly connected to the upper movable plate 220, thereby enabling the upper movable plate 220 to move up and down when the telescopic rod of the telescopic cylinder 210 reciprocates. The bottom of the upper movable plate 220 is provided with a shaping structure 400 for shaping the upper end face of the stator coil. The shaping structure 400 is fixedly connected to the upper movable plate 220 through the upper pad 221, thereby enabling the telescopic cylinder 210 to drive the shaping structure 400 to move up and down reciprocally.

[0025] like Figure 3As shown, the lower mold mechanism 300 includes a flipping pad 310. A flipping shaft is integrally provided on the side of the flipping pad 310 near the lower base plate 111 of the frame base 110. Both ends of the flipping shaft are rotatably mounted on the fixing blocks of the lower base plate 111, allowing the flipping pad 310 to rotate and flip around the flipping shaft. A shaping structure 400 for shaping the lower end face of the stator coil is installed on the side of the flipping pad 310 facing the operator. A flipping piston 320 for controlling the flipping of the flipping pad 310 is connected to its back side. The flipping piston 320 is located inside the frame base 110 and is obliquely installed towards the flipping pad 310. A piston hole 112 is provided on the lower base plate 111 on the rear side of the flipping pad 310. The piston rod of the flipping piston 320 passes through the piston hole 112 and is movably connected to the back side of the flipping pad 310, allowing the flipping piston 320 to control the rotation and flipping movement of the flipping pad 310.

[0026] When the piston rod of the flipping piston 320 extends, the flipping pad 310 gradually rises until it is perpendicular to the lower base plate 111. At this time, the shaping working end face of the shaping structure 400 faces the operator. The operator can horizontally install the stator coil to be processed on the shaping structure 400, or remove the finished stator coil from the shaping structure 400. Compared with existing stator finishing machines, this utility model is more efficient and convenient for installing and replacing stators, eliminating the need for the operator to work at a desk, and is more ergonomic. When the piston rod of the flipping piston 320 retracts, the flipping pad... Plate 310 gradually descends to fit against the lower base plate 111. At this time, the shaping working end face of the shaping structure 400 of the lower mold mechanism 300 faces the shaping structure 400 of the upper mold mechanism 200. The upper and lower shaping structures 400 are set in a corresponding manner, eliminating the need for the operator to manually adjust the upper and lower molds. Under the action of the telescopic cylinder 210, the shaping structure 400 of the upper mold mechanism 200 is pressed down, realizing the synchronous fine shaping of the upper and lower end faces of the stator coil, which effectively improves the processing efficiency, ensures the processing quality of the stator coil, and reduces the operator's labor costs.

[0027] To further explain, the lower mold mechanism 300 has positioning posts 331 perpendicular to the front side of the shaping structure 400 where the stator coil is installed. The positioning posts 331 facilitate the positioning of the stator coil during installation. Below the positioning posts 331, an arc-shaped stator bracket 332 for supporting the stator is provided extending from the bottom of the shaping structure 400. An adjusting seat 340 is provided on the lower base plate 111 on the front side of the shaping structure 400. The adjusting seat 340 includes rotating plates 341 at its front and rear ends and several transmission shafts 342 connected to the top of the rotating plates 341. The top of the rotating plates 341 is arc-shaped, and its top height and arc angle are consistent with those of the stator bracket 332.

[0028] like Figure 4As shown, the shaping structure 400 achieves stator precision shaping through the expansion of the inner core and the contraction of the outer cavity. The inner core of the shaping structure 400 mainly includes a stretching rod 410 and several expansion blocks 420 arranged in a ring shape. The top of the stretching rod 410 is fixedly connected to the upper movable plate 220 or the flip pad 310, and a conical head 411 is formed at the bottom. A limiting seat 412 is sleeved on the stretching rod 410 between the conical head 411 and the upper pad 221 or the flip pad 310 through a fixing nut 413. The top of the limiting seat 412 is fixedly connected to the bottom of the upper pad 221 or the flip pad 310, and the fixing nut 413 is fixedly connected to the bottom of the limiting seat 412. The expansion blocks 420 are all installed inside the annular expansion block ring 421. As the tapered head 411 of the expansion rod 410 gradually sinks into the central hole of the expansion block ring 421, it is squeezed by the outer surface of the tapered head 411, and the expansion blocks 420 will expand outward to achieve the inner ring shaping of the stator coil.

[0029] The outer cavity of the shaping structure 400 mainly includes an inclined top rod 440, a downward positioning block 450, and a downward connecting block 460. The downward positioning block 450 and the downward connecting block 460 are spaced apart to form a ring structure. Each end of the outer wall of the downward positioning block 450 has a top rod groove 451. The top of the inclined top rod 440 is fixedly connected to the upper pad 221 or the flip pad 310, and the bottom has a keyway milled out and extends into the top rod groove 451 to move in conjunction with the downward positioning block 450 to achieve the shaping of the outer ring of the stator coil.

[0030] To further explain, in order to protect the inner core and outer cavity of the shaping structure 400, a fixing cover 430 is provided on the outside of the expansion block 420, the push positioning block 450, and the push connecting block 460. The fixing cover 430 is fixedly connected to the upper pad 221 or the flip pad 310 by fixing screws 431. The inclined top rod 440 passes through the fixing cover 430. The expansion block ring 421 and the expansion block 420 are installed together inside the fixing cover 430, and the top of the expansion block ring 421 is fixedly connected to the fixing cover 430. The bottom of the fixing cover 430 is connected to the bottom of the push positioning block 450 and the push connecting block 460 with an annular fixing plate 470. When the stator coil is installed, its upper and lower end faces pass through the fixing plate 470 to abut against the inner bottom surface of the fixing cover 430.
