The fixture is easy to operate, produces good forming results, and features a crank-slider structure pressing mechanism. The mechanism has a simple structure, making it easy for employees to operate. The deformation force of the spring can drive the connecting axis to move upward and automatically reset after the shaping is completed, reducing the workload of employees. The cylinder structure pressing mechanism has high work repeatability and can achieve automated control. However, the above-mentioned shaping tooling is only applicable to the shaping of the housing of the same model of motor and is not applicable to the shaping of housings of various different models of motors. This affects the applicability and utilization rate of the above-mentioned shaping tooling to a certain extent, thus affecting the practicality of the above-mentioned shaping tooling. Therefore, in order to solve the above problems, this utility model proposes a shaping tooling for micro motor housings. Utility Model Content

[0004] The present invention aims to provide a shaping fixture for micro motor housings, which can be applied to the shaping of housings of various micro motor models, thereby enriching the scope of application of the fixture, improving its utilization rate, and ensuring its practicality.

[0005] This utility model is achieved through the following technical solution:

[0006] A shaping fixture for a micro motor housing includes a base and a shaping mechanism. The shaping mechanism is located on top of the base, and an auxiliary support mechanism is located at one end of the base. The shaping mechanism includes two support rods, the inner sides of which are mounted on a mounting plate. Multiple first mounting shafts arranged in a linear array are located above one of the support rods. Multiple second mounting shafts, corresponding in number and position to the first mounting shafts, are located on the side of the mounting plate near the first mounting shafts. A first connecting rod is detachably connected between the second and first mounting shafts. Multiple shaping dies with different inner diameters are mounted inside the mounting plate. A shaping punch is located inside the cavity of each shaping die. A cylinder is located above one of the shaping punches. A base plate is located at the bottom inner side of the shaping die. A push rod is connected to the lower center of the base plate. The auxiliary support mechanism includes a second bearing plate. Two auxiliary rods are symmetrically arranged above the second bearing plate, and a second sliding groove is located on the side of each auxiliary rod that is close to it.

[0007] As a further feature of the above solution, the base includes a first support plate, on both sides of which are symmetrically connected two first pins. On both sides of the second support plate near the first support plate, there are second pins. A second connecting rod is detachably connected between the second pins and the first pins, which facilitates adjusting the installation position of the second support plate according to actual usage requirements and fixing it with the second connecting rod.

[0008] As a further feature of the above solution, each of the two support rods has a first sliding groove on its side closest to each other, and both sides of the mounting plate have protruding plates. The protruding plates are slidably connected to the first and second sliding grooves, which helps the mounting plate to slide smoothly in the first and second sliding grooves when changing the forming die aligned with the cylinder.

[0014] In this invention, the cavity depth of different types of forming dies is adapted to the model of the cavity, and the length of the push rod extending out of the cavity from the bottom plate in different cavities is the same.

[0015] The present invention has the following beneficial effects during use:

[0016] The combination of the first slide groove and the convex plate in the forming mechanism allows the convex plate to slide in the first slide groove according to the model of the motor housing to be formed, so as to adjust the position of the forming die and the forming punch aligned with the cylinder, thereby improving the practicality of the tooling. The combination of multiple first mounting shafts, second mounting shafts and first connecting rods can fix the position of the mounting plate after the position of the mounting plate and the forming die and other components are adjusted.

[0017] The combination of push rod, push plate and telescopic rod can extend the telescopic rod after the housing is shaped, drive the push plate to move upward and push the push rod, so as to push the motor housing out of the forming die cavity, making it convenient for the user to take the housing out of the die cavity.

[0018] The combination of the second pin and the second link in the auxiliary support mechanism enables the auxiliary support mechanism to be installed at one end of the mounting plate in the target direction of movement, so that the auxiliary rod is connected to the support rod through the connecting shaft and nut to provide support for the part of the mounting plate that extends out of the support rod, so that the mounting plate and its connecting parts remain stable during the housing shaping process.

A connecting head 281 is connected to the telescopic end of the cylinder 28. The connecting head 281 and the connecting block 272 are detachably connected, which facilitates the disassembly and assembly of the connecting head 281 and the connecting block 272. A bracket 29 is connected to the outside of the cylinder 28, which can provide stable support for the cylinder. A telescopic rod 261 is provided on the front side of the bracket 29. A push plate 26 is connected to the telescopic end of the telescopic rod 261. The push plate 26 is aligned with the push rod 251 located directly below the cylinder 28, which helps the push plate 26 to push the push rod 251 and the base plate 25, so as to push the formed motor housing out of the mold cavity of the forming die 24.

[0034] like Figure 4 As shown, the outer side of the push rod 251 is engaged with a buckle 252, which can restrict the position of the bottom plate 25 and the push rod 251 below it inside the idle forming die 24, so that the push rod 251 and the bottom plate 25 remain stable.

[0035] like Figure 1As shown, a protective sleeve 273 is provided on the outer side of the connecting block 272, which can keep the inside and outside of the connecting block 272 clean and facilitate the connection between the connecting block 272 and the connecting head 281.

[0036] like Figure 1 and Figure 6 As shown, a controller 4 and a storage box 5 are respectively provided on the upper side of the first support plate 11 and the second support plate 31, which facilitates the control of the operation of the relevant components in the tooling and facilitates the placement of accessories such as buckles 252 and protective covers 273 for users to access.

[0037] The micro motor housing shaping fixture disclosed in this embodiment requires selecting a suitable shaping die 24 and its matching shaping punch 27 according to the model of the housing to be shaped before use. After selection, the two ends of the multiple first connecting rods 233 are sequentially separated from the first mounting shaft 213 and the second mounting shaft 232, respectively. The first connecting rods 233 are placed aside, and the two ends of the two second connecting rods 33 are sequentially separated from the first pin 12 and the second pin 32, respectively. After adjusting the position of the auxiliary support mechanism 3 to one end of the target movement direction of the mounting plate 23, the two connecting shafts 212 are inserted into the two connecting holes 342, and screws are tightened on the outside of the connecting shafts 212. Mother 343, restore the connection between the second connecting rod 33 and the first pin 12 and the second pin 32, fix the auxiliary support mechanism 3, push the mounting plate 23 towards the target direction, so that one end of the protrusion 231 slides from the first slide groove 211 into the second slide groove 341. When the shaping die 24 is moved to the bottom of the cylinder 28, connect the two ends of the first connecting rod 233 to the first mounting shaft 213 and the second mounting shaft 232 respectively, fix the position of the mounting plate 23. At this time, the push plate 26 is located directly below the target shaping die 24. Remove the protective sleeve 273 from the top of the shaping protrusion 27 in the target shaping die 24 and place it in the storage box 5.

[0038] The controller 4 controls the extension of cylinder 28, causing cylinder 28 to move connector head 281 toward connector block 272. After connector head 281 and connector block 272 are in full contact, connector block 272 above forming punch 27 in target forming die 24 is connected to connector head 281. After connection, the controller 4 controls cylinder 28 to retract, pulling forming punch 27 out of forming die 24. The shell to be formed is placed into the mold cavity of forming die 24. The controller 4 controls cylinder 28 to extend, pushing forming punch 27 into the inside of shell, so that forming punch 27 and forming die 24 squeeze shell from the inside and outside of shell respectively, achieving shell forming. After forming, the controller 4 controls cylinder 28 to retract, pulling forming punch 27 completely out of shell. The buckle 252 located directly below cylinder 28 is removed from outside push rod 251 and placed in... Meanwhile, the controller 4 controls the extension of the telescopic rod 261, which drives the push plate 26 to move upward and push the push rod 251. The push rod 251 causes the bottom plate 25 and the upper inner side of the mold cavity of the shaped shell forming die 24 to move, pushing the shell out from the inside of the forming die 24. The user removes the shell from the forming die 24 and controls the telescopic rod 261 to retract. The bottom plate 25 and the push rod 251 move downward under the action of gravity until the bottom plate 25 moves to the bottom of the mold cavity of the forming die 24. After placing another shell to be shaped into the forming die 24, the operation of controlling the extension and retraction of the cylinder 28 is repeated to continue the corresponding shell shaping operation. Alternatively, the shell to be shaped can be placed on the outside of the forming punch 27, and the shell and the forming punch 27 can be pushed together into the mold cavity of the forming die 24 for shaping during the extension of the cylinder 28.
