Description

Technical Field

[0001] The utility model belongs to the technical field of graphite ring grinding, and specifically relates to a graphite ring grinding and fixing device. Background Art

[0002] A graphite ring is a ring-shaped product of different sizes made by molding flexible graphite tape or flexible graphite braided packing. Due to its good self-lubrication and high resilience coefficient, it is widely used in the sealing of mechanical rotating parts. During the production process of graphite rings, if their surfaces need to be ground, a fixing device needs to be used in advance to fix them to ensure the grinding quality.

[0003] The Chinese patent document with the authorization announcement number CN219542677U discloses a graphite ring grinding and fixing device. It places the graphite ring to be ground on a liftable fixing plate arranged in the support structure, and then clamps the placed graphite ring from both sides through rubber pads installed on the protection mechanism, thus quickly completing the clamping and fixing of the graphite ring.

[0004] However, in the prior art, after the graphite ring is fixed, its surface will be largely blocked, so that the staff needs to move, flip and repeat the clamping of the graphite ring many times to fully grind it. Therefore, a graphite ring grinding and fixing device is proposed. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a graphite ring grinding and fixing device.

[0006] The technical solution adopted by the utility model is as follows:

[0007] A graphite ring grinding and fixing device includes a loading component that can stably place the device. A fixing component for fixing the graphite ring and preventing its surface from being largely blocked is arranged on the loading component, and an adjusting component for adjusting the clamping degree of the graphite ring is arranged on one side of the fixing component.

[0008] The fixing component includes a clamping member for placing and effectively fixing the graphite ring, a limiting member for restricting the movable range of the clamping member in the device, and a shifting member for adjusting the horizontal position of the clamping member according to the specification of the graphite ring under the action of the adjusting component.

[0009] Preferably: The shifting member includes a fixed frame fixedly installed on the loading component. A bidirectional lead screw is movably connected between the fixed frames. One end of the bidirectional lead screw is fixedly connected with a synchronous pulley, and a synchronous belt is arranged between the synchronous pulleys.

[0010] Preferably: The limiting member includes a limiting plate arranged under the fixed frame, and a limiting frame is fixedly connected between the bidirectional lead screws.

[0011] Preferably, the clamping member includes a support rod disposed between the limiting plate and the limiting frame. A carrier is fixedly connected to the lower end of the support rod. A conical roller is movably installed in the carrier, and a supporting roller is movably installed on one side of the carrier.

[0012] Preferably, the fixing frame is rotatably connected to the bidirectional lead screw.

[0013] Preferably, the bidirectional lead screw is threadedly connected to the limiting frame.

[0014] Preferably, both the limiting plate and the limiting frame are slidably connected to the support rod.

[0015] Preferably, both the conical roller and the supporting roller are rotatably connected to the carrier.

[0016] Preferably, the diameter of the conical roller gradually decreases from top to bottom.

[0017] The beneficial effects of the present utility model are as follows: It is convenient to use multiple limiting members that can simultaneously move horizontally in a fixed direction to contact the graphite ring to be polished in a small area at different positions, so that the graphite ring placed in this device can be stably clamped while the staff can contact most of its surface, and at the same time, the shielded part of the graphite ring can be easily adjusted to ensure the polishing completion degree and overall polishing efficiency after a single clamping of the graphite ring.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood through specific situations.

[0027] The present invention will be further described below with reference to the embodiments and the accompanying drawings.

[0028] As Figures 1-4 shown, a graphite ring grinding and fixing device includes a loading component 1 that can stably place the device. A fixing component 2 that can fix the graphite ring and prevent its surface from being largely blocked is arranged on the loading component 1. An adjusting component 3 that can adjust the clamping degree of the graphite ring is arranged on one side of the fixing component 2.

[0029] In this embodiment: The loading component 1 includes a frame 101, and a diagonal bracing plate 102 is fixedly installed on the frame 101; the frame 101 provides an installation position for some components of the fixing component 2 and the adjusting component 3, and the diagonal bracing plate 102 further improves the stability of the frame 101.

[0030] In this embodiment: The fixing component 2 includes a clamping member that can place and effectively fix a graphite ring, a limiting member that can limit the movable range of the clamping member within the device, and a shifting member that can adjust the horizontal position of the clamping member according to the specifications of the graphite ring under the action of the adjusting component 3. The shifting member includes a fixed frame 201 fixedly installed on the loading component 1. A bidirectional lead screw 202 is movably connected between the fixed frames 201. One end of the bidirectional lead screw 202 is fixedly connected to a synchronous pulley 203, and a synchronous belt 204 is arranged between the synchronous pulleys 203. The limiting member includes a limiting plate 205 arranged below the fixed frame 201. A limiting frame 206 is fixedly connected between the bidirectional lead screws 202. The clamping member includes a support rod 207 arranged between the limiting plate 205 and the limiting frame 206. The lower end of the support rod 207 is fixedly connected to a carrier 208. A conical roller 209 is movably installed in the carrier 208, and a supporting roller 210 is movably installed on one side of the carrier 208;

[0031] The fixed frame 201 is rotatably connected to the bidirectional lead screw 202. The bidirectional lead screw 202 is threadedly connected to the limiting frame 206. Both the limiting plate 205 and the limiting frame 206 are slidably connected to the support rod 207. Both the conical roller 209 and the supporting roller 210 are rotatably connected to the carrier 208. The diameter of the conical roller 209 gradually decreases from top to bottom;

[0032] The bidirectional lead screw 202 capable of adjusting the lateral position of the limiting frame 206 is installed in the frame 101 through the fixed frame 201. The two bidirectional lead screws 202 can rotate at the same speed through the synchronous pulleys 203 and the synchronous belt 204. The movable range of the support rod 207 is jointly limited by the limiting plate 205 and the limiting frame 206. The carrier 208 is driven to move horizontally within the device by the support rod 207 connected to the limiting frame 206. The surface of the graphite ring is contacted by the conical roller 209 and the supporting roller 210 installed in the carrier 208. After tightly abutting against the graphite ring, the conical roller 209 can also limit the vertical movement of the graphite ring.

[0033] In this embodiment: The adjusting component 3 includes a bracket 301 fixedly installed on the frame 101. A worm 302 is movably installed in the bracket 301. The lower end of the worm 302 is fixedly connected to a knob 303. One end of one of the bidirectional lead screws 202 is fixedly connected to a worm gear 304;

[0034] The bracket 301 is rotatably connected to the worm 302, and the worm 302 is meshed with the worm gear 304; the worm 302 is installed in the frame 101 through the bracket 301, so that the worm 302 can be located on one side of the bidirectional lead screw 202 connected with the worm gear 304, so as to connect the worm 302 and the worm gear 304, and the worm 302 can be conveniently rotated through the knob 303.

[0035] Working principle: When this device is installed and completed for the fixed work of graphite ring grinding, according to the size specification of the graphite ring, the worm 302 is rotated through the knob 303, so that the worm gear 304 can drive the two bidirectional lead screws 202 to rotate simultaneously, so as to adjust the horizontal position of the limit frame 206. Since the limit frame 206 after horizontal movement can drive the support rod 207 to move, and the movable range of the support rod 207 is limited by the limit plate 205, the support rod 207 will stably drive the carrier 208 to move horizontally along a fixed direction;

[0036] When the graphite ring can be placed above each idler roller 210, and the conical roller 209 can press against the side of the graphite ring from different directions, the graphite ring can be ground. Since the contact areas of the conical roller 209 and the idler roller 210 with the graphite ring are limited, and both the conical roller 209 and the idler roller 210 can rotate relative to the carrier 208, when grinding the graphite ring, the staff can conveniently adjust the shielded part of the graphite ring by rotating the graphite ring or rotating the worm 302 and adjusting the clamped part of the graphite ring, so as to quickly complete the full grinding of the graphite ring.

[0037] The preferred embodiments of the present utility model have been described in detail above in conjunction with the accompanying drawings, but the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the purpose of the present utility model.
