Description

Technical Field

[0001] The utility model relates to the field of magnet product processing, in particular to a shaft inserting device for a magnetic sheet cylinder. Background Art

[0002] During the forming process of some electromagnetic motors, the rotor inside includes a magnetic cylinder and a central shaft. A plurality of magnetic sheets are evenly arrayed on the circumference of the magnetic cylinder, wherein the magnetic cylinder and the central shaft are connected by an interference fit. The magnetic sheets on the outer ring stator drive the magnetic cylinder to rotate, thereby driving the central shaft to rotate, so as to realize the conversion of magnetic energy into kinetic energy.

[0003] In some motors, the center shaft needs to pass through the magnetic cylinder to facilitate the center shaft to achieve double-end drive or other double-end functions, but this can easily cause the center shaft to be longer, and problems such as inaccurate installation depth and installation interference may occur during the installation of the center shaft, which in turn causes installation quality problems between the center shaft and the magnetic cylinder. Summary of the invention

[0004] The technical problem to be solved by the utility model is to provide a shaft inserting device for a magnetic sheet drum which can ensure the installation accuracy of the magnetic sheet drum and the central shaft and avoid interference during the installation process.

[0005] The technical solution adopted by the utility model to solve the above-mentioned problem is: a shaft insertion device for a magnetic film tube, comprising a main body, the main body is used to insert a central shaft on the axis of the magnetic film tube, the main body includes a fixed base for fixing the magnetic film tube, a clamping seat for clamping the central shaft is provided above the fixed base, the clamping seat is connected to the top of the fixed base by movement along the vertical direction, the fixed base is provided with a fixing groove for fixing the magnetic film tube, the groove bottom axis of the fixing groove is provided with an avoidance hole for the central shaft to pass through, the fixed base is connected to the inside of the device by movement along the horizontal direction, and when the central shaft is installed on the clamping seat, the fixed base leaves the installation station.

[0006] Compared with the prior art, the utility model has the following advantages: during the installation process, the central axis is clamped by a clamping seat, which is arranged above the fixed groove, and an avoidance hole for the central axis to pass through is provided at the bottom of the fixed groove. When the clamping seat moves with the central axis toward the fixed base to insert the central axis into the magnetic film cylinder, the magnetic film cylinder will not move due to the limit of the bottom of the fixed groove, and the central axis can continue to penetrate the avoidance hole after being inserted into the magnetic film cylinder, thereby ensuring the penetration depth of the central axis and making the insertion depth between the central axis and the magnetic film cylinder accurate. At the same time, because the central axis The length of the central shaft is relatively long. When installing the central shaft into the clamping seat, there may be installation interference between the central shaft and the fixed base, making it difficult to install the central shaft into the fixed base. Therefore, the fixed base is designed to be movable. When installing the central shaft, the fixed base leaves the installation position to facilitate the insertion of the central shaft into the clamping seat. After the installation of the central shaft is inserted into the clamping seat, the fixed base is reset to the installation position to insert the central shaft into the magnetic film tube, thereby avoiding the installation interference problem caused by the excessive length of the central shaft and making the installation process smoother.

[0007] As an improvement of the present invention, the fixed base is fixedly connected to a moving platform, the moving platform has moving guide rails on both sides, and a driving motor is provided at one end of the moving platform in the moving direction. Through the improvement and the design of the driving motor, the accuracy of the movement of the fixed base can be ensured, and the fixed base can maintain an accurate moving distance during the process of moving away from the installation position and then resetting to the installation position. The design of the moving guide rails on both sides can ensure the stability of the movement of the fixed base and avoid the deflection of the fixed base during the movement, thereby ensuring that the fixed base remains coaxial with the center axis after moving away and resetting, thereby ensuring the accuracy of the installation.

[0008] As an improvement of the present utility model, the fixed base includes an adjustment base and a movable base, the fixed groove is arranged in the movable base, and the movable base can be movably connected to the upper end of the adjustment base, and the upper end of the adjustment base is provided with an adjustment groove for the movable base to be movably connected, and the setting direction of the adjustment groove is perpendicular to the moving direction of the fixed base. Through the improvement, in order to ensure the versatility of the equipment, the equipment will be designed to be adjustable. When installing different magnetic film tubes and central axes, the axis position of the alignment may be offset. When the clamping seat moves in the vertical direction, the change of its coaxial movement is reduced. On the fixed base, it can complete the change in one direction of the coaxial movement by adjusting the moving parameters through the moving function of the driving motor. At this time, it only needs to add an adjustment structure in the same horizontal plane and perpendicular to the moving direction of the fixed base to complete the coaxial movement change requirements. The vertical design is more convenient for adjustment and control. Therefore, when replacing different magnetic film tubes and central axes, the parameters of the moving seat and the driving motor are used to adjust the new alignment axis to ensure the accuracy of the central axis insertion.

[0009] As an improvement of the utility model, spiral adjustment push rods are provided at both ends of the adjustment groove along the moving direction, long waist holes are provided along the moving direction of the moving seat at the four corners of the moving seat, and fixing holes corresponding to the long waist holes are provided on the adjustment seat. After the adjustment of the moving seat is completed, the long waist holes and the fixing holes are connected by fasteners to fix the adjustment seat and the moving seat. Through the improvement, when the moving seat is adjusted, the adjustment distance is very small. The adjustment through the spiral adjustment push rod has the same principle as that of a jack, which belongs to a conventional structure. The amplitude of manual adjustment can be expanded to ensure the small distance adjustment of the moving seat, thereby realizing coaxial high-precision alignment. After completing the coaxial movement alignment, the moving seat is fixed on the adjustment seat, and the design of the long waist holes is to ensure that the moving seat and the adjustment seat can still be fixedly connected after the movement adjustment.

[0010] As an improvement of the present invention, the movable seat includes a connecting block and a mounting block, the mounting block is fixedly connected to the upper end of the connecting block, the avoidance hole is arranged in the connecting block, the slot hole of the fixing groove is arranged in the mounting block, and the slot bottom of the fixing groove is the upper surface of the connecting block. Through the improvement, the movable seat is designed in a split manner, the fixing groove is processed on the mounting block, and the avoidance hole is processed on the connecting block, so that the processing of the movable seat is easier. At the same time, as long as the height of the upper end surface of the connecting block is guaranteed, the installation height of the magnetic sheet tube can be guaranteed. Compared with processing a blind hole fixing slot, the processing accuracy is also higher, so that the insertion depth of the center axis can be more accurate.

[0011] As an improvement of the present invention, the connecting block and the mounting block are fixedly connected by fasteners, and limit strips are provided on opposite sides of the connecting block, and limit planes are provided on opposite sides of the mounting block, and the two limit planes are respectively abutted against the two limit strips. Through the improvement, because the connecting block and the mounting block are fixedly connected by fasteners, when the fasteners are tightened and fixed, the mounting block is prone to slight deflection, which can easily cause coaxial offset of the fixing groove. Through the design of the limit strips abutting against the limit planes, the deflection of the mounting block during the tightening of the fasteners can be avoided, thereby better ensuring the accuracy of the center axis insertion into the magnetic sheet tube.

[0012] As an improvement of the utility model, a first detection probe for detecting the presence or absence of a magnetic film tube is provided on both sides of the installation station. Through the improvement, it is used to confirm that a magnetic film tube has been installed on the fixed base when the fixed base is at the installation station, so that the central axis can be inserted and installed to avoid invalid movement of the central axis.

[0013] As an improvement of the present invention, the clamping seat includes a pneumatic connecting tube, which has four clamping blocks evenly arrayed in the circumferential direction. When the center shaft is inserted into the pneumatic connecting tube, the pneumatic connecting tube controls the four clamping blocks to approach the center shaft and clamp the center shaft through air pressure. Through the improvement, after the center shaft is inserted into the pneumatic connecting tube and abuts against the bottom of the pneumatic connecting tube, the pneumatic connecting tube controls the four clamping blocks to clamp the center shaft, which can ensure the uniformity of force on the center shaft after clamping and ensure the plug-in stability of the center shaft.

[0014] As an improvement of the utility model, a clamping opening is provided at the clamping connection between the clamping block and the central axis, and the clamping opening is provided with two clamping surfaces tangent to the surface of the central axis. Through the improvement, the abutment surface is increased by clamping with four clamps, which can enhance the centrality and stability of the clamping block on the central axis.

[0015] As an improvement of the utility model, the lower end of the pneumatic connecting tube is provided with a second detection probe for detecting the presence of a center axis. Through the improvement, it is used to confirm whether there is a center axis on the clamping seat, thereby avoiding invalid action of the clamping seat when inserting and installing the center axis.
