Description

Technical Field

[0001] The invention relates to a component processing tooling equipment, in particular to an H-type vertical processing tooling for a motor base. Background Art

[0002] The motor base is the main structural part of the motor, which has a great influence on the interchangeability and uniformity of the air gap of the motor. Generally, the motor base is a thin-walled part that is easy to deform. Its machining is relatively complicated. The quality requirements of each main processing surface must be comprehensively considered to determine the mounting support method. When the existing fixture is used for mounting, the motor base H is fixed by over-positioning. Since the motor base H is a thin-walled part, there is deformation during mounting, which affects the wall thickness, center height and flatness of the base after processing. Summary of the invention

[0003] The present invention provides a vertical support tooling structure for flexible machining of a motor base in order to solve the problem that the existing clamping base is over-positioned, deformed during mounting and the machining accuracy of the base is affected.

[0004] The technical solution adopted by the present invention to solve the above technical problems is:

[0005] A vertical support tooling structure for flexible processing of a motor base comprises a clamping platform, a positioning tire, an angle adjustment mechanism, a floating support mechanism and a clamping mechanism. The positioning tire is processed with an outer cylindrical surface boss that matches the inner hole of the motor base. The positioning tire is fixedly arranged on the clamping platform. The inner surface of the motor base matches the outer cylindrical surface boss of the positioning tire. The motor base is fixed by the clamping mechanism. At least three floating support mechanisms evenly distributed along the axis of the motor base are fixedly arranged on the clamping platform. The floating support mechanism floats the motor base and is arranged with a gap with the outer cylindrical surface boss.

[0006] Preferably, the angle adjustment mechanism includes a flip frame that flips up and down, and a straight rod that cooperates with the ground of the motor base is provided on the flip frame. The flip frame is hinged on the clamping platform, and a locking part is provided on the clamping platform. The flip frame is rotated to make the straight rod stick to the ground of the motor base and be locked by the locking part.

[0007] Preferably, the locking portion includes a locking screw, a slot is provided on the flip frame, the locking screw is threadedly connected to the clamping platform, and when the straight rod on the flip frame is flush with the ground of the motor base, the locking screw is rotated so that the end of the locking screw enters the slot of the flip frame to fix the flip frame.

[0008] Preferably, each floating support mechanism comprises a support column, a compression spring and a sleeve, the support column is slidably arranged in the sleeve and can move up and down, the sleeve is fixedly connected to the clamping platform, and a compression spring is arranged between the support column and the clamping platform.

[0009] Preferably, there are multiple outer cylindrical bosses on the positioning tire, which are arranged in a stepped manner and are used to clamp motor bases of different models and specifications.

[0010] Preferably, the clamping mechanism includes a pull rod, a pressure plate, a nut and a flange. The pull rod is detachably connected to the positioning tire, the flange is fixedly connected to the pressure plate, the nut is threadedly connected to the pull rod, the pressure plate is sleeved on the pull rod, the nut is pressed on the upper surface of the flange and spherically matched with the upper surface of the flange, and the motor base is arranged between the pressure plate and the positioning tire.

[0011] Preferably, the flange and the pressing plate are both provided with notches for disassembling the flange and the pressing plate.

[0012] The pressing plate is provided with at least three clamping claws for fixing the motor base.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] The present invention floats and fixes the motor base through a floating support mechanism and a clamping mechanism. Compared with the existing over-positioning clamping, it has one degree of freedom along the axial direction and is under-positioning. It does not affect the subsequent processing of the motor base and can prevent deformation during installation. The rotation direction of the motor base is limited by the angle adjustment mechanism, which can accurately ensure the processing accuracy and center height of the bottom surface of the motor base.

[0020] The present invention will be further described in detail below in conjunction with the accompanying drawings: This embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation method is given, but the protection scope of the present invention is not limited to the following embodiments.

[0021] Example 1: Combined with Figure 1-Figure 5To illustrate the present embodiment, the present embodiment relates to a vertical support tooling structure for flexible processing of a motor base, comprising a mounting platform 1, a positioning tire 2, an angle adjustment mechanism 3, a floating support mechanism 4 and a clamping mechanism 5. The positioning tire 2 is processed with an outer cylindrical surface boss 2-1 that cooperates with the inner hole of the motor base H. The positioning tire 2 is fixedly arranged on the mounting platform 1. The inner surface of the motor base H cooperates with the outer cylindrical surface boss 2-1 on the positioning tire 2. The motor base H is fixed by the clamping mechanism 5. At least three floating support mechanisms 4 evenly distributed along the axis of the motor base H are fixedly arranged on the mounting platform 1. The floating support mechanism 4 floats the motor base H and is arranged with a gap with the outer cylindrical surface boss 2-1.

[0022] In order to limit the rotation of the motor base H to ensure that the bottom surface of the motor base H does not deviate, optionally, as Figure 2 As shown, the angle adjustment mechanism 3 includes a flip frame 3-1 that flips up and down, and a straight rod 3-2 that cooperates with the ground of the motor base H is provided on the flip frame 3-1. The flip frame 3-1 is hingedly set on the card loading platform 1, and a locking part 6 is provided on the card loading platform 1. The flip frame 3-1 is rotated to make the straight rod 3-2 stick to the ground of the motor base H and be locked by the locking part 6.

[0023] After the angle adjustment mechanism 3 adjusts the angle of the motor base H, in order to further lock the angle adjustment mechanism 3, optionally, as Figure 2 As shown, the locking portion 6 includes a locking screw, a slot is provided on the flip frame 3-1, and the locking screw is threadedly connected to the clamping platform 1. When the straight rod 3-2 on the flip frame 3-1 is flush with the ground of the motor base H, the locking screw is rotated so that the end of the locking screw enters the slot of the flip frame 3-1 to fix the flip frame 3-1.

[0024] In order to ensure reliable locking, multiple notches and locking screws can be provided, wherein the notches are circular and the ends of the locking screws are processed into cylindrical shapes, and the two cooperate with each other to ensure positioning accuracy.

[0025] After the clamping mechanism 5 clamps the motor base H, in order to set the motor base H and the outer cylindrical boss 2-1 with a certain gap, the floating support mechanism 4 is set, optionally, as Figure 4 and Figure 5 As shown, each floating support mechanism 4 includes a support column 4-1, a compression spring 4-2 and a sleeve 4-3, the support column 4-1 is slidably arranged in the sleeve 4-3 and can move up and down, the sleeve 4-3 is fixedly connected to the clamping platform 1, and a compression spring 4-2 is arranged between the support column 4-1 and the clamping platform 1. When the clamping mechanism 5 clamps and fixes, the distance between the end of the motor base H and the outer cylindrical surface boss 2-1 can be about 2mm to ensure the floating fixation of the motor base H and prevent the clamping force from being too large to cause deformation.

[0026] There are multiple outer cylindrical bosses 2-1 on the positioning tire 2, which are arranged in a stepped manner and are used to clamp motor bases H of different models and specifications. In order to facilitate the placement of the floating support mechanism 4 and lift the motor base H, multiple grooves can be opened on the positioning tire 2, and the floating support mechanism 4 is set in the grooves and evenly arranged along the axis of the motor base H. In order to make the floating support mechanism 4 applicable to the support of various motor models, multiple protrusions 411 with different heights and distributed along the radial direction can be set on the top of the support column 4-1, and the multiple protrusions 411 correspond to the multiple outer cylindrical bosses 2-1 one by one. Each protrusion 411 can be cylindrical and arranged horizontally to ensure accurate positioning.

[0027] Optionally, the clamping mechanism 5 includes a pull rod 5-1, a pressure plate 5-2, a nut 5-3 and a flange 5-4, the pull rod 5-1 is detachably connected to the positioning tire 2, the flange 5-4 is fixedly connected to the pressure plate 5-2, the nut 5-3 is threadedly connected to the pull rod 5-1, the pressure plate 5-2 is sleeved on the pull rod 5-1, the nut 5-3 is pressed on the upper surface of the flange 5-4 and spherically matched with the upper surface of the flange 5-4, and the motor base H is arranged between the pressure plate 5-2 and the positioning tire 2. Through the spherical match between the nut 5-3 and the flange 5-4, the pressure plate 5-2 presses the motor base H, which can make the force on the motor base H more uniform.

[0028] In order to further make the force on the motor base H uniform, at least three clamping claws 521 can be set on the pressing plate 5-2 to reduce the force-bearing surface of the motor base H and avoid deformation caused by local uneven force.

[0029] The flange 5-4 and the pressing plate 5-2 are both provided with notches for disassembling the flange 5-4 and the pressing plate 5-2. By loosening the nut 5-3, the flange 5-4 and the pressing plate 5-2 can be quickly disassembled from the pull rod 5-1.

[0030] Although the present invention has been described in detail through some specific embodiments, it should be understood by those skilled in the art that the above examples are only for illustration and not for limiting the scope of the present invention. It should be understood by those skilled in the art that the above embodiments may be modified without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
