For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] Ginseng Figures 1 to 11 As shown, a steel sleeve feeding device comprises a horizontally arranged workbench 1 and a steel sleeve conveying device 2, a pressing fixture 3 and a pressing device 4 arranged on the workbench 1. The steel sleeve conveying device 2 comprises a gantry 21 fixed to the workbench 1 and a steel sleeve clamp 23 reciprocatingly moved by a conveying cylinder 22. The pressing fixture 3 comprises a mounting fixture 31 sliding on the workbench 1. The pressing device 4 comprises a supporting frame 41 fixed to the workbench 1, a pressure device 42 arranged on the top of the supporting frame 41 and a pressing frame 43 drivingly connected to the pressure device 42.

[0032] In this technical solution, conventional PLC and other control devices, as well as cables, air pipes, wire ducts and tank chains are also provided on the outside. The specific structure and control principle, etc., are all existing technologies and will not be described here one by one. Conventional process holes and chamfers are provided on the surface of the parts to facilitate processing and measurement. The workbench is horizontally arranged through profiles and table foot bolts. The gantry is a conventional structure and is fixed to the top surface of the workbench by bolts. The transport cylinder uses an existing rodless cylinder and is fixed to the gantry by bolts, etc., which drives the horizontal reciprocating movement of the steel sleeve fixture. The steel sleeve fixture moves the external material tray / The steel sleeve in a conventional material storage device such as a material tube is clamped to one end of a press-fitting jig and placed in the installation jig. The installation jig slides to the other end of the press-fitting jig. A rotor equipped with magnetic tiles is inserted into the steel sleeve manually or by an external manipulator. The installation jig slides to the bottom of the pressure device. The pressure device drives the press-fitting frame to complete the press-fitting. The installation jig slides to the end of the press-fitting jig. A manual or external manipulator takes out the pressed rotor and steel sleeve to start the next cycle of loading and pressing. The steel sleeve loading device has a compact structure and is used for automatic loading and pressing of rotor steel sleeves, thereby improving work efficiency and precision.

[0033] For example, see Figure 1 and Figure 2 As shown, the steel sleeve clamp 23 includes a lifting cylinder 231 fixed to the slider of the transport cylinder 22 and a first finger cylinder 232 fixed to the slide of the lifting cylinder 231. The fingers of the first finger cylinder 232 are respectively connected to the first clamps 233. The inner side surface of the first clamps 233 (the side where the two first clamps are close to each other) is provided with an arc groove corresponding to the steel sleeve.

[0034] In this technical solution, the lifting cylinder uses an existing slide cylinder and is fixed to the slider of the transport cylinder by bolts. After the first clamp clamps or puts down the steel sleeve, the lifting cylinder drives the first finger cylinder and the first clamp to rise to avoid interference with the installation fixture and the external storage device during the reciprocating movement. The arc groove increases the contact area between the first clamp and the steel sleeve, thereby improving the clamping effect. The arc groove is a blind groove structure in its axial direction. When the steel sleeve enters the installation fixture, the top wall of the arc groove abuts against the top surface of the steel sleeve, ensuring that the bottom of the steel sleeve enters the installation fixture, thereby improving the loading accuracy.

[0035] For example, see Figures 3 to 7 As shown, the mounting fixture 31 includes a mounting plate 311 and a positioning sleeve 312 fixed to the top of the mounting plate 311. The mounting plate 311 is slidably set on the workbench 1 through a buffer seat, and a mounting hole is set on its top surface. The bottom of the positioning sleeve 312 is embedded in the mounting hole, and a step hole corresponding to the steel sleeve and the rotor is set at the center of the top surface of the positioning sleeve 312.

[0036] In this technical solution, the positioning and installation of the locating sleeve is facilitated by the arrangement of the mounting plate. The locating sleeve is fixed to the mounting plate by bolts and locating pins. The locating sleeve is an annular structure, and its inner wall is a stepped hole structure, which is respectively arranged corresponding to the outer walls of the steel sleeve and the rotor. The step corresponding to the steel sleeve is recessed with a clearance groove corresponding to the protrusion of the bottom wall of the steel sleeve to avoid deformation of the steel sleeve after press-fitting; the bottom of the locating sleeve is protruding with a locating pin corresponding to the rotor to improve the consistency of press-fitting of the rotor and the steel sleeve. Before press-fitting, the locating pin and the through hole on the rotor are aligned manually or by an external manipulator, and the rotor is preliminarily press-fitted so that the top end of the locating pin enters the through hole on the rotor to avoid damage to the rotor. Both sides of the mounting plate are provided with a corresponding sensor for confirming that the rotor enters the locating sleeve.

[0037] For example, see Figures 3 to 7 As shown, the buffer seat includes a cushion seat 32 fixed to the workbench 1, a buffer plate 34 sliding on the cushion seat 32 through a first guide rail 33, and a driving motor 35 connected to the buffer plate 34. The mounting plate 311 is slidably set on the top of the buffer plate 34 through a guide column 36. A buffer spring 37 is arranged between the mounting plate 311 and the buffer plate 34, and the buffer spring 37 is sleeved on the corresponding guide column 36.

[0038] In this technical solution, the raising seat includes a raising plate and support blocks supported at both ends of the raising plate to prevent the bottom plate of the support frame from interfering with the first guide rail and other settings. The first guide rail is close to one end of the steel sleeve handling device for the steel sleeve loading position, and the mounting fixture is directly below the steel sleeve fixture. The other end of the first guide rail is the rotor loading position, which is convenient for inserting the rotor into the steel sleeve of the mounting fixture by manual or conventional manipulators. The first guide rail is located directly below the pressure device for the pressing position, and the pressure device completely presses the rotor into the steel sleeve. The driving motor drives the mounting fixture to reciprocate along the first guide rail between the steel sleeve loading position, the rotor loading position and the pressing position through the buffer plate. The driving motor uses a conventional servo motor, which cooperates with conventional sensors to control the position of the mounting fixture. The driving motor is connected to the buffer plate through a conventional screw pair drive, wherein the nut seat of the screw pair is connected to the buffer plate through a connecting plate; the mounting plate is slidably connected to the buffer plate through a guide column, and a buffer spring is provided between the mounting plate and the buffer plate to avoid rigid collision between the pressing device and the rotor during the pressing process.

[0039] For example, see Figures 3 to 7 As shown, the bottom end of the guide column 36 protrudes from the bottom surface of the buffer plate 34 and is connected to the pressure plate 38. A pressure block 5 is arranged directly below the press-fitting frame 43. The pressure block 45 is fixed to the top surface of the bottom plate of the support frame by bolts, etc., and an avoidance groove corresponding to the pressure block 5 is arranged inside the cushion seat 32. A pressure boss 381 corresponding to the pressure block 5 protrudes from the bottom surface of the pressure plate 38. After the pressure boss contacts the pressure block, the bottom surface of the pressure plate and the top surface of the bottom surface of the support frame are spaced apart, and no force is generated on the bottom plate of the support frame during the press-fitting process.

[0040] In this technical solution, a linear bearing corresponding to the guide column is arranged in the buffer plate. During the press-fitting process, the installation jig and the guide column slide downward. After the pressure-bearing boss of the pressure plate contacts the pressure block, the pressure block bears the pressure of the pressure device to complete the press-fitting of the rotor and the steel sleeve. It can also avoid direct pressure on the buffer plate, thereby extending the service life of the guide rail. After the press-fitting is completed, the press-fitting device is reset, and the installation jig is reset under the action of the buffer spring; a limiting column is arranged on the bottom surface of the buffer plate, which cooperates with the buffer spring to limit the height of the installation jig. The buffer spring is in a compressed state and applies an upward force to the installation jig. The limiting column acts on the installation jig through the pressure plate and the guide column to keep the installation jig stable. During the resetting process, the resetting is completed when the top surface of the pressure plate abuts against the bottom surface of the limiting column.

[0041] For example, see Figure 1 As shown, the support frame 41 includes a bottom plate and a top plate arranged opposite to each other and support rods respectively arranged between the bottom plate and the top plate. The bottom plate is fixed to the workbench 1. The pressure device 42 is a pressure cylinder and is vertically fixed to the top of the top plate. Its piston rod movably passes through the top plate and is connected to the press frame 43. The press frame 43 is movably connected to the corresponding support rods.

[0042] In this technical solution, the support rod adopts a conventional optical axis structure, with bolts protruding from both ends, and is fixed to the corresponding bottom plate and top plate by nuts, etc., and the workbench is provided with clearance holes corresponding to the support rod nuts, etc. The pressure device adopts a conventional air cylinder or oil cylinder, etc. to drive the press frame and complete the press fitting.

[0043] For example, see Figure 1 as well as Figures 8 to 11 As shown, the press-fitting frame 43 includes a press-fitting plate 431 slidably connected to the corresponding support rod and a press-fitting head 432 fixed to the bottom of the press-fitting plate 431 , and the top end of the press-fitting plate 431 is connected to the piston rod of the pressure device 42 through a connecting head.

[0044] In this technical solution, both ends of the press plate are slidably connected to the corresponding support rods through conventional structures such as linear bearings or sleeves, thereby improving the accuracy and stability of the movement of the press plate and thus improving the accuracy of the press fitting. A buffer corresponding to the press plate is provided on the support rod to avoid rigid contact between the press plate and the rotor. The connecting head includes a T-head and two semicircular blocks. The bottom surface of the semicircular block is provided with an arc groove with the T-head. The T-head is connected to the bottom surface of the press plate, thereby realizing the connection between the pressure devices of the press plate.

[0045] For example, see Figure 1 as well as Figures 8 to 11 As shown, a pressure sensor 6 is arranged between the connecting head and the piston rod of the pressure device 42 .

[0046] In this technical solution, the pressure sensor is a conventional structure, which is used to monitor the pressure of the press fitting, avoid damage to the rotor and the steel sleeve caused by excessive pressure, and inadequate press fitting caused by insufficient pressure, thereby improving the consistency of the press fitting.

[0047] For example, see Figure 1 as well as Figures 8 to 11 As shown, the bottom surface of the press-fitting head 432 is concavely provided with a press-fitting groove corresponding to the rotor, the bottom surface of the press-fitting head 432 is convexly provided with a press-fitting boss corresponding to the magnetic tile, and the press-fitting head 432 is provided with a guide device 433 corresponding to the steel sleeve, and the guide device 433 includes a second finger cylinder fixed to the press-fitting head 432 through a bracket and a second clamp respectively connected to the fingers of the second finger cylinder.

[0048] In this technical solution, the press-fitting groove and the press-fitting boss press-fit the top of the rotor and the magnetic tile at the same time to prevent the magnetic tile from detaching from the surface of the rotor during the press-fitting process. After the rotor and the magnetic tile are press-fitted to the bottom wall of the steel sleeve, the steel sleeve is driven downward together until the bottom surface of the steel sleeve contacts the corresponding step of the positioning sleeve to ensure the press-fitting effect. After the press-fitting head moves down to the top of the rotor, the second finger cylinder drives the second clamp to close, and the arc groove on the inner side of the second clamp engages with the surface of the steel sleeve to straighten the steel sleeve to avoid press-fitting damage caused by installation deviation of the steel sleeve. The second clamp is made of nylon or the like. After engaging with the surface of the steel sleeve, it can slide along the surface of the steel sleeve, that is, during the press-fitting process, the second clamp slides synchronously along the surface of the steel sleeve. The installation height and thickness of the second clamp are controlled to ensure that when the press-fitting is in place, the second clamp and the positioning sleeve are set at intervals to avoid interference with the normal operation of the press-fitting.

[0049] For example, see Figure 1 as well as Figures 8 to 11 As shown, a displacement sensor 7 is provided at the top of the top plate through the vertical plate, and the measuring block of the displacement sensor 7 is connected to the piston rod of the pressure device 42 through a connecting rod 8, and the connecting rod 8 is slidably connected to the vertical plate through a second guide rail.

[0050] In this technical solution, the displacement sensor is an existing structure, which is used to monitor the moving distance of the pressing head and cooperate with the pressure sensor to improve the consistency of pressing. A conventional position sensor is arranged on the side of the support frame through the mounting rod, etc., and the corresponding end of the pressing plate is connected with a sensing sheet for monitoring the position of the pressing plate; the connecting rod slides through the top plate of the support frame, and the measuring block of the displacement sensor is connected to the piston rod of the pressure device, so that the movement of the piston rod of the pressure device is monitored through the displacement sensor. In order to improve the stability and accuracy of the movement of the connecting rod, the connecting rod is slidably connected to the vertical plate through the second guide rail.

[0051] In summary, the steel sleeve feeding device has a compact structure and is used for automatic feeding and press-fitting of rotor steel sleeves, thereby improving work efficiency and precision.

[0052] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0053] The above is only a specific implementation of the present utility model. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present utility model. These improvements and modifications should also be regarded as the protection scope of the present utility model.
