Description

Technical Field

[0001] The utility model relates to the technical field of flywheel processing, in particular to a flywheel plane processing tooling. Background Art

[0002] A flywheel is a disc-shaped part with a large moment of inertia. Its function is like an energy storage device, which can be used to reduce the speed fluctuation during the operation of the engine. When processing a flywheel, a positioning tooling is required to position it to ensure the processing accuracy of the flywheel.

[0003] The existing patent CN 219666368 U, a new type of flywheel processing tooling, realizes the rapid positioning of the installation shaft hole at the center of the flywheel through a conical column. And because the outer diameters of different heights of the conical column are different, it can adapt to the installation shaft holes of different specifications of flywheels, thus improving the practicability of the equipment. The lifting of the support member is realized through the first transmission member to improve the support stability of the flywheel. The two support columns are driven to move towards each other through the second transmission member, and then it can meet the use of flywheels with different outer diameters. Driven by the compression spring, the lifting frame drives the pressing block to press on the surface of the flywheel, thus solving the problem that the traditional tooling cannot fix flywheels of different specifications.

[0004] However, during the use of the existing patent, a new type of flywheel processing tooling, although the device can fix flywheels of different specifications, when face milling the flywheel plane is required, due to the occlusion of the flywheel plane by the lifting frame and the pressing block, this will affect the movement stroke of the face milling cutter, thus bringing inconvenience to the face milling processing. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a flywheel plane processing tooling, which solves the problem that although the aforementioned device can fix flywheels of different specifications, when face milling the flywheel plane is required, due to the occlusion of the flywheel plane by the lifting frame and the pressing block, this will affect the movement stroke of the face milling cutter, thus bringing inconvenience to the face milling processing.

[0006] To achieve the above object, the present utility model provides a flywheel plane processing tooling, which includes a base, a support rod, a processing seat and a jacking device. The support rod is fixedly installed on the base, the processing seat is fixedly installed on the support rod, a boss is provided on the processing seat, the jacking device is installed on the processing seat, and a positioning device is further included. The positioning device includes a positioning gear, a connecting shaft, a sliding block, a driving plate and a driving component. A chute is provided on one side of the processing seat, and a through groove is further provided on the side of the processing seat close to the chute. The through groove penetrates the chute. The sliding block is slidably installed on the processing seat and is located in the chute. The connecting shaft is fixedly installed on the sliding block, the positioning gear is fixedly installed on the connecting shaft, the driving plate is fixedly installed on the sliding block and penetrates the through groove, and the driving component drives the driving plate to move.

[0007] Wherein, the driving component includes a motor and a cam. The motor is fixedly installed on the processing seat; the cam is fixedly installed on the output shaft of the motor and is close to the driving plate.

[0008] Wherein, the positioning device further includes a return spring, and both ends of the return spring are fixedly connected to the processing seat and the sliding block respectively.

[0009] Wherein, the positioning device further includes a central rod, and the central rod is fixedly installed on the boss.

[0010] Wherein, the jacking device includes a jacking cylinder and a jacking block. The jacking cylinder is fixedly installed on the processing seat; the jacking block is fixedly installed on the output end of the jacking cylinder.

[0011] When the flywheel plane processing tooling of the present utility model is in use, the flywheel is placed on the boss, and the central rod passes through the central hole of the flywheel. Then the motor is started, so that the motor drives the cam to rotate. The rotation of the cam pushes the driving plate to move along the through groove to one side of the boss. The movement of the driving plate drives the sliding block to move along the chute through the fixed connection with the sliding block. One side of the sliding block drives the positioning gear to move accordingly through the connection of the connecting shaft, and the positioning gear is meshed with the teeth on the side of the flywheel. Under the combined action of the three groups of positioning gears, the flywheel is clamped, so that the positioning of the side of the flywheel is realized through the movement of the three groups of positioning gears, and the processing plane of the flywheel is not affected.

Specific embodiments

[0017] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present utility model, and should not be construed as a limitation to the present utility model.

[0018] The first embodiment of the present application is as follows:

[0019] Please refer to Figure 1 and Figure 2 , Figure 1 It is a schematic diagram of the overall structure of a flywheel flat machining tooling according to the first embodiment of the present utility model, Figure 2 It is a schematic diagram of the structure of the driving component according to the first embodiment of the present utility model.

[0020] The present utility model provides a flywheel flat machining tooling: including a base 101, a support rod 102, a machining seat 103 and a lifting device, and further including a positioning device. The positioning device includes a positioning gear 105, a connecting shaft 106, a sliding block 107, a driving plate 108 and a driving component. The driving component includes a motor 111 and a cam 112. The positioning device further includes a return spring 113. The positioning device further includes a center rod 114. By the foregoing solution, the problem that although the foregoing device can fix flywheels of different specifications, when face milling machining is required for the flywheel flat surface, due to the shielding of the flywheel flat surface by the lifting frame and the pressing block, this will affect the movement stroke of the face milling cutter, thus bringing inconvenience to the face milling machining can be solved. It can be understood that this solution can also be used to solve the problem of flywheel discharging.

[0021] In this embodiment, driven by the driving component, the driving plate 108 drives the positioning gear 105 to position the flywheel through the sliding block 107 and the connecting shaft 106. Thus, through the movement of the three groups of positioning gears 105, the positioning of the side of the flywheel is achieved without affecting the machining plane of the flywheel.

[0022] Wherein, a sliding groove 109 is provided on one side of the machining seat 103, and a through groove 110 is further provided on the side of the machining seat 103 close to the sliding groove 109. The through groove 110 penetrates through the sliding groove 109. The sliding block 107 is slidably installed on the machining seat 103 and is located within the sliding groove 109. The connecting shaft 106 is fixedly installed on the sliding block 107, the positioning gear 105 is fixedly installed on the connecting shaft 106, the driving plate 108 is fixedly installed on the sliding block 107 and penetrates through the through groove 110. The driving component drives the driving plate 108 to move. The number of both the sliding groove 109 and the through groove 110 is three, and they are annularly distributed on the machining seat 103. A group of sliding blocks 107 are provided in each group of sliding grooves 109. The connecting shaft 106 is welded to the upper surface of the sliding block 107, and the positioning gear 105 is welded to the upper end of the connecting shaft 106. The axis of the positioning gear 105 coincides with that of the connecting shaft 106. During use, the driving component drives the driving plate 108 to move along the through groove 110 towards one side of the boss 104. The driving plate 108 drives the positioning gear 105 to move towards one side of the boss 104 under the connection and cooperation of the sliding block 107 and the connecting shaft 106, and makes the positioning gear 105 mesh with the teeth on the side of the flywheel. Thus, through the movement of the three groups of positioning gears 105, the positioning of the side of the flywheel is achieved without affecting the machining plane of the flywheel.

[0023] Secondly, the motor 111 is fixedly installed on the machining seat 103; the cam 112 is fixedly installed on the output shaft of the motor 111 and is close to the driving plate 108. The motor 111 is fixed to the lower surface of the machining seat 103 by screws. The cross-section of the cam 112 is elliptical. The motor 111 drives the cam 112 to rotate, and the rotation of the cam 112 pushes the driving plate 108, thereby achieving the pushing effect on the driving plate 108.

[0024] Again, both ends of the reset spring 113 are fixedly connected to the processing base 103 and the sliding block 107 respectively. The number of the reset springs 113 is three groups, and they are respectively located in the three groups of chutes 109. The reset springs 113 are welded on the sliding block 107. Through the arrangement of the reset springs 113, after the sliding block 107 moves, it can be reset under the elastic force of the reset springs 113.

[0025] Finally, the central rod 114 is fixedly installed on the boss 104. The central rod 114 is fixed at the center of the boss 104, and the axis of the central rod 114 coincides with the axis of the boss 104. When installing the flywheel, the central rod 114 passes through the central hole of the flywheel. Thus, through the arrangement of the central rod 114, it is convenient to position the flywheel at the center of the boss 104.

[0026] In this embodiment, during use, the flywheel is placed on the boss 104, and the central rod 114 passes through the central hole of the flywheel. Then the motor 111 is started, so that the motor 111 drives the cam 112 to rotate. The rotation of the cam 112 pushes the drive plate 108 to move along the through groove 110 to one side of the boss 104. The movement of the drive plate 108 drives the sliding block 107 to move along the chute 109 through being fixedly connected with the sliding block 107. One side of the sliding block 107 drives the positioning gear 105 to move accordingly through the connection of the connecting shaft 106, and makes the positioning gear 105 engage with the teeth on the side of the flywheel. Under the combined action of the three groups of positioning gears 105, the flywheel is clamped. Thus, through the movement of the three groups of positioning gears 105, the positioning of the side of the flywheel is realized, and the processing plane of the flywheel will not be affected.

[0027] The second embodiment of this application is as follows:

[0028] Please refer to Figure 3 , in which Figure 3 is the overall structural schematic diagram of a flywheel plane processing tooling according to the second embodiment of the present utility model. On the basis of the first embodiment, the flywheel plane processing tooling of this embodiment further includes a jacking device, and the jacking device includes a jacking cylinder 201 and a jacking block 202.

[0029] In this embodiment, through the cooperation of the jacking cylinder 201 and the jacking block 202, the discharging of the flywheel is realized.

[0030] Among them, the lifting cylinder 201 is fixedly installed on the processing seat 103; the lifting block 202 is fixedly installed at the output end of the lifting cylinder 201. The number of the lifting devices is two groups, and they are symmetrically distributed on both sides of the convex platform 104. The lifting cylinder 201 is fixed on the upper surface of the processing seat 103 by screws. The lifting block 202 is disc-shaped and made of rubber material. After the flywheel processing is completed, the lifting cylinder 201 is started to drive the lifting block 202 to move upward and push the flywheel upward, so that the central hole of the flywheel is separated from the central rod 114, thereby realizing the discharging of the flywheel.

[0031] In this embodiment, after the flywheel processing is completed, the lifting cylinder 201 is started to drive the lifting block 202 to move upward and push the flywheel upward, so that the central hole of the flywheel is separated from the central rod 114, thereby realizing the discharging of the flywheel.
