DETAILED DESCRIPTION

[0032] Please refer to Figures 1-3 In the embodiment of the application, the shaft grounding ring processing equipment comprises a bottom plate 1, a supporting cylinder 2 is fixedly connected and arranged on the bottom plate 1, a bearing disc 6 is slidingly matched and arranged on the periphery of the supporting cylinder 2, a gasket ring 5 is installed and arranged at the end of the supporting cylinder 2 away from the bottom plate 1, a plurality of first through holes 51 are throughly arranged on the periphery of the gasket ring 5, a limiting protrusion 52 is slidingly matched and arranged in the first through hole 51, a driving assembly for driving the limiting protrusion 52 away from the first through hole 51 is installed and arranged on the bearing disc 6, a plurality of sliding grooves 62 are throughly arranged on the bearing disc 6, a clamping assembly 63 is slidingly matched and arranged in the sliding groove 62, and an adjusting ring 7 for driving a plurality of clamping assemblies 63 to move synchronously towards the gasket ring 5 is assembled and arranged on the side of the bearing disc 6 away from the gasket ring 5.

[0033] In use, when the shaft grounding ring needs to be machined on the outer side of the opening, the opening cover can be placed on the periphery of the grommet 5, the opening edge is placed on the surface of the bearing disc 6, and under the action of gravity, the bearing disc 6 slides along the support cylinder 2 to the direction of the bottom plate 1, so that the bearing disc 6 can drive the limiting protrusion 52 to slide out of the first through hole 51, thereby clamping the inner side of the shaft grounding ring, so that the shaft grounding ring can be automatically limited under the action of gravity, and the outer side of the opening of the shaft grounding ring can be machined conveniently; when the inner side of the opening of the shaft grounding ring needs to be machined, the opening of the shaft grounding ring faces upward, and the adjusting ring 7 can be adjusted to move the plurality of clamping assemblies 63 synchronously to the grommet 5, so that the shaft grounding ring can be clamped by the plurality of clamping assemblies 63, and the inner side of the opening of the shaft grounding ring can be machined conveniently. The structure design is convenient for flexible machining of the inner and outer sides of the shaft grounding ring, is flexible and convenient to adjust, has higher applicability, and has the positioning and clamping effects.

[0034] The support cylinder 2 and the bottom plate 1 are connected and surrounded by the protective bushing 3, the protective bushing 3 is fixedly connected to the bottom plate 1, and the protective bushing 3 can assist in supporting the support cylinder 2 to prevent the support cylinder 2 from shaking.

[0035] Further, the clamping assembly 63 comprises a sliding block 6301 slidingly fitted in the sliding groove 62, the adjusting ring 7 and the sliding block 6301 are in transmission connection, the sliding block 6301 has a “U” shape, the opening of the sliding block 6301 is away from the grommet 5, two sides of the opening of the sliding block 6301 are symmetrically embedded with mounting grooves 6302, and the opening of the sliding block 6301 movably fits with an L-shaped rod 6303, two sides of the end of the L-shaped rod 6303 extending into the sliding block 6301 are symmetrically provided with protrusions in active fit with the mounting grooves 6302. When the L-shaped rod 6303 is rotated to above the bearing disc 6, the free end of the L-shaped rod 6303 is bent toward one side of the grommet 5, the protrusions have a prism structure, the mounting grooves 6302 are composed of a prism-shaped groove and a cylindrical groove in communication, the prism-shaped groove is correspondingly matched with the protrusions, the protrusions are rotationally matched with the cylindrical groove, and the prism-shaped groove is arranged on the side away from the grommet 5.

[0036] In use, when the protrusion at the end of the L-shaped rod 6303 engages in the prismatic groove, the L-shaped rod 6303 cannot rotate relative to the slider 6301. When the L-shaped rod 6303 is needed to clamp the shaft grounding ring, the protrusion at the end of the L-shaped rod 6303 is moved toward the cylindrical groove. This allows rotation through the opening side of the slider 6301. After the turning part of the L-shaped rod 6303 rotates toward the washer 5, the protrusion at its end is moved back into the prismatic groove. In this way, when multiple sets of L-shaped rods 6303 clamp the contact shaft grounding ring, they can be centered and clamped. Moreover, under the action of force, the protrusion at the end of the L-shaped rod 6303 can also remain in the prismatic groove.

[0037] The sliding grooves 62 are distributed in a cross shape on the support plate 6, and the end of the sliding grooves 62 passes through the outer edge of the support plate 6. Preferably, a guide groove can be added between the slider 6301 and the inner side of the sliding grooves 62 to prevent the slider 6301 from being misaligned and falling off during sliding.

[0038] To facilitate the control of the movement of the limit protrusion 52 by the bearing plate 6, such as Figures 4-6 As shown, a second through hole 61 is provided through the middle of the bearing plate 6. The support cylinder 2 slides through the second through hole 61. Slotted holes 21 are symmetrically provided through both sides of the support cylinder 2, extending axially along the support cylinder 2. A connecting rod 64 is fixedly connected to the inner side of the second through hole 61, sliding through the slotted hole 21. A collar 65 is fixedly connected to the end of the connecting rod 64 extending into the support cylinder 2. A spring is connected between one end of the collar 65 and the bottom of the support cylinder 2. A boss 66, which is an inverted frustum structure, is fixedly connected to the other end of the collar 65. When the shaft grounding ring is not placed, the boss 66 is located above the end of the limiting protrusion 52. When the shaft grounding ring is placed on the bearing plate 6, the weight of the shaft grounding ring causes the bearing plate 6 to move downwards. The edge of the boss 66 pushes the limiting protrusion 52 to slide outwards in the first through hole 51, and the edge of the limiting protrusion 52 can abut against the inner side of the opening of the shaft grounding ring.

[0039] The limiting protrusion 52 is a cylindrical structure. A ball head 5201 is fixedly provided at the end of the limiting protrusion 52 that extends into the support cylinder 2. The end face radius of the ball head 5201 is larger than the end face radius of the limiting protrusion 52. A spring connects the ball head 5201 and the inner wall of the support cylinder 2. When the boss 66 moves and presses against the ball head 5201, the end of the limiting protrusion 52 moves outward from the support cylinder 2. When the boss 66 moves upward away from the ball head 5201, the limiting protrusion 52 can retract into the support cylinder 2.

[0040] like Figures 7-9As shown, the second through hole 61 is fixedly connected with a gear slot 68 on the outer periphery of one side of the gasket ring 5, the gear slot 68 is slidably sleeved on the outer periphery of the support cylinder 2, the inner side of the opening of the gear slot 68 is embedded with a toothed groove, the end of the adjusting ring 7 is connected with the gear slot 68 through a spring, and the adjusting ring 7 is located on the outer periphery of the support cylinder 2. Wherein, the end of the adjusting ring 7 is slidably inserted into the gear slot 68, and the outer periphery is provided with a second limiting tooth 71 matched with the toothed groove in the gear slot 68, a wire wheel 72 is sleeved on the outer periphery of the adjusting ring 7, a traction rope 73 is connected on the wire wheel 72, the traction rope 73 is connected in a cross shape on the wire wheel 72, and the ends of the traction rope 73 away from the wire wheel 72 are respectively connected with the corresponding sliding blocks 6301. Preferably, the traction rope 73 is in a tight state at ordinary times, when it is necessary to control the relative movement of the plurality of sliding blocks 6301 and drive the L-shaped rod 6303 to be relatively clamped, it is only necessary to pull out the end of the adjusting ring 7 from the gear slot 68, so that the second limiting tooth 71 is disengaged from the toothed groove on the inner side of the gear slot 68, at this time, rotating the adjusting ring 7 can make the traction rope 73 wind around the outer periphery of the wire wheel 72, and drive the L-shaped rod 6303 to be relatively clamped, after clamping is completed, the end of the adjusting ring 7 is pushed into the gear slot 68, so that the second limiting tooth 71 and the toothed groove in the gear slot 68 are matched again, so that the clamping is stable. In order to facilitate resetting, springs can be connected in the sliding blocks 6301 and the sliding grooves 62, so that the adjusting ring 7 can be pulled out after clamping is completed, and then reversed to reset the sliding blocks 6301.

[0041] As shown in Figure 1 , Figures 10-12 , the support cylinder 2 is provided with a core rod 44, both ends of the core rod 44 are provided with a threaded joint 4402, both sides of the core rod 44 are symmetrically provided with a guide rib 4401, the guide rib 4401 is arranged in the axial direction of the core rod 44, the sleeve ring 65 and the boss 66 are provided with a third through hole 67 at the center, the core rod 44 is slidably arranged through the third through hole 67, and the inner wall of the third through hole 67 is embedded with a rib groove matched with the guide rib 4401, the gasket ring 5 is fixedly connected with a gasket plate 53 at the end away from the support cylinder 2, the surface of the gasket plate 53 is embedded with a rubber pad layer, the inner side of the gasket plate 53 is fixedly connected with a second threaded cylinder 54 matched with the threaded joint 4402 at the center, and the end face of the second threaded cylinder 54 is flush with the edge of the gasket ring 5. When in use, the second threaded cylinder 54 can be aligned with the threaded joint 4402 and assembled by threaded connection, and when the opening of the shaft joint ring is machined, the gasket ring 5 can be removed, which is easier to install and clamp.

[0042] In order to avoid the threaded joint 4402 above the upper end of the supporting cylinder 2 affecting the installation of the shaft grounding ring, the bottom of the base plate 1 is rotationally fitted with a first threaded cylinder 43, which is connected to the threaded joint 4402 at the lower end of the core rod 44 through threaded fitting, and the end of the first threaded cylinder 43 extends from the bottom of the base plate 1 and is connected to the assembly washer 42 through spline fitting, the assembly washer 42 is fixedly connected to the adjusting knob 4, a spring is connected between the assembly washer 42 and the bottom of the base plate 1, the spring and the assembly washer 42 are rotationally fitted through the bearing ring, the first limiting tooth 41 is fixedly arranged on the edge of the adjusting knob 4 opposite to the bottom of the base plate 1, and a toothed groove is arranged opposite to the first limiting tooth 41 on the bottom of the base plate 1. Normally, the adjusting knob 4 is attached to the bottom of the base plate 1 under the action of the spring, the first limiting tooth 41 and the toothed groove are fitted, and the first threaded cylinder 43 is restricted from rotating at this time. When the opening of the shaft grounding ring needs to be machined, the adjusting knob 4 is pulled down, the first limiting tooth 41 is disengaged from the toothed groove, and the adjusting knob 4 can drive the first threaded cylinder 43 to rotate at this time. The first threaded cylinder 43 can drive the core rod 44 to rise and fall through threaded fitting, the cooperation between the guiding rib 4401 on the surface of the core rod 44 and the inner wall of the third through hole 67 can restrict the rotation of the core rod 44, so that the core rod 44 rises and falls stably, and the core rod 44 can be conveniently received into the supporting cylinder 2, so that the shaft grounding ring can be better installed. After the adjusting knob 4 is loosened, the adjusting knob 4 is retracted and attached to the bottom of the base plate 1 under the action of the spring, the first limiting tooth 41 and the toothed groove on the bottom of the base plate 1 restore cooperation, and the adjusting knob 4 and the first threaded cylinder 43 are restricted from rotating, so that the installation of the core rod 44 can also be restored to be stable.
