A grinding device for wave plate processing

Abstract

This utility model relates to the field of waveplate processing technology and discloses a grinding device for waveplate processing, including a base with a positioning pit machined on the top. After the waveplate is placed in the positioning pit, the telescopic column can be controlled to extend, causing the displacement plate to move downwards. The grinding disc then contacts the top of the waveplate, and a drive motor runs to grind the top of the waveplate. During grinding, a water outlet connected to an external water pipe discharges water to the top of the waveplate to assist the grinding disc in grinding. When the displacement plate moves downwards, it abuts against the retaining ring of the limiting rod, causing the cover to move downwards. The cover then engages with the top of the outer component, thus blocking the water splashed out by the rotating grinding disc. The water then flows into the interior of the outer component, preventing water containing powder from being splashed out and contaminating other structures of the grinding device, facilitating the grinding operation of the waveplate.

Description

Technical Field

[0001] This utility model relates to the field of wave plate processing technology, specifically a grinding device for wave plate processing. Background Technology

[0002] A waveplate is an optical element that uses birefringence to change the polarization state of polarized light. It consists of two optical crystal plates with different refractive indices. When light passes through the waveplate, the speed of light in one direction differs from that in the other, causing a phase difference and thus achieving a polarization transformation. Common waveplates include half-wave plates and full-wave plates, used to adjust polarization direction and phase difference, and in fields such as optical detection and optical communication. When manufacturing circular waveplates, a grinding device is required to polish the surface of the waveplate.

[0003] Existing grinding devices for waveplate processing typically include a base and support frame for positioning the waveplate, followed by a grinding disc on top to grind the top of the waveplate. The grinding operation is performed by a drive motor fixed to the support frame that rotates the grinding disc. During grinding, water is usually sprayed onto the top of the waveplate. However, the rotation of the grinding disc during grinding can cause grinding powder to be thrown out with the water, which can easily contaminate the external structure of the grinding device and is not conducive to long-term grinding of the waveplate. Therefore, we propose a grinding device for waveplate processing. Utility Model Content

[0004] The purpose of this invention is to provide a grinding device for wave plate processing to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a grinding device for wave plate processing, comprising a base, a positioning pit machined on the top of the base, a drainage component disposed on the outside of the base, a support member fixedly connected to the side wall of the base, a grinding component disposed inside the support member, and an outer cover component fitted to the outside of the grinding component, the outer cover component covering the top of the drainage component.

[0006] Preferably, the drainage assembly includes a drainage channel disposed on the side wall of the positioning pit, an outer component fixed to the outside of the base, and a drainage outlet fixed to the side wall of the outer component.

[0007] Preferably, the grinding assembly includes a telescopic column passing through the support member, a displacement plate fixed to the bottom of the telescopic column, a drive motor embedded in the top of the displacement plate, a grinding component disposed at the power output end of the drive motor, and a grinding disc disposed at the bottom of the grinding component.

[0008] Preferably, the outer cover assembly includes a cover body, a limiting rod fixed to the top of the cover body, a water outlet head disposed on the top of the cover body, and a fixing ring fixed to the top of the limiting rod.

[0009] Preferably, a retaining ring is fixed to the outer wall of the limiting rod, the retaining ring is fitted to the bottom of the displacement plate, and the limiting rod passes through the top of the displacement plate.

[0010] Preferably, the top of the support member is fixedly connected to a fastener that cooperates with the limiting rod, and the limiting rod is sleeved with a long spring that cooperates with the fastener.

[0011] Preferably, the cover fits onto the top of the outer component, and the exterior of the cover is machined with mating holes.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model involves placing a corrugated plate in a positioning pit, then controlling the extension of a telescopic column to move a displacement plate downwards. The grinding disc then contacts the top of the corrugated plate, and a drive motor rotates to grind the top of the corrugated plate. During grinding, a water outlet connected to an external water pipe discharges water to the top of the corrugated plate, cooperating with the grinding component. As the displacement plate moves downwards, it presses against the retaining ring of the limiting rod, causing the cover to move downwards. The cover then engages with the top of the outer component, thus shielding the water ejected by the rotating grinding component. The water then flows into the interior of the outer component, preventing water containing powder from being ejected and contaminating other structures of the grinding device, facilitating the grinding operation of the corrugated plate.

[0014] 2. In this utility model, when the displacement plate moves downward, the cover moves downward. At this time, the limiting rod moves downward in conjunction with the displacement plate. Then, the limiting rod also moves downward at the top of the support. At this time, the limiting rod can limit the cover and the displacement plate at the same time, making the displacement plate and the cover more stable when moving up and down. It can resist the torque of the drive motor when it is running, so that the telescopic column can extend and retract stably. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example

[0022] Please see Figures 1-4 The diagram shows a grinding device for processing wave plates, including a base 100, a positioning pit 101 machined on the top of the base 100, a drainage component provided on the outside of the base 100, a support member 110 fixed to the side wall of the base 100 by bolts, a grinding component provided inside the support member 110, and an outer cover component fitted to the outside of the grinding component, the outer cover component covering the top of the drainage component.

[0023] Specifically, the drainage assembly includes a drainage channel 102 disposed on the side wall of the positioning pit 101, an outer component 120 fixed to the outside of the base 100 by bolts, and a drainage outlet 121 fixed to the side wall of the outer component 120 by bolts. The positioning pit 101 has notches on both sides, and water can flow out from the notches and then enter the outer component 120 through the drainage channel 102.

[0024] Furthermore, the grinding assembly includes a telescopic column 140 that passes through and is bolted to the support member 110, a displacement plate 141 that is bolted to the bottom of the telescopic column 140, a drive motor 142 that is embedded in the top of the displacement plate 141 and bolted to it, a grinding element 143 that is located at the power output end of the drive motor 142, and a grinding disc 144 that is located at the bottom of the grinding element 143. The telescopic column 140 uses a commercially available electric actuator. The electric actuator is usually composed of a motor, a transmission system, and a actuator. The working principle of the electric actuator is that the motor drives the transmission system to make the actuator move linearly. At the same time, the motors of the two telescopic columns 140 are electrically connected to the same forward / reverse switch. The forward / reverse switch usually contains electrical contacts and circuits that cooperate with the forward and reverse buttons. By changing the state of the contacts, the two telescopic columns 140 can move forward or in reverse at the same time. The forward / reverse switch is powered by an external circuit connected to a power cord. The grinding disc 144 is cut from a common diamond abrasive.

[0025] Furthermore, the outer casing assembly includes a casing 130, a limiting rod 150 bolted to the top of the casing 130, a water outlet 131 located on the top of the casing 130, and a retaining ring 152 tightly welded to the top of the limiting rod 150. The water outlet 131 is made of commonly available stainless steel tubing. The output end of the water outlet 131 is fitted into the interior of the casing 130 and is connected to an external water pump using a common rubber hose. The external water pump is a commonly available model and has an external water tank connected to its input end. Water from the tank can be pumped to the water outlet 131 to drain water to the top of the waveplate.

[0026] In some embodiments, a large, commercially available rubber suction cup can be fixed inside the positioning pit 101 of the base 100 with bolts. The opening of the suction cup faces upward. After the wave plate is placed inside the positioning pit 101, pressing the wave plate will cause the wave plate to adhere to the suction cup, thereby achieving the positioning of the wave plate.

[0027] Furthermore, a retaining ring 151 is tightly welded to the outer wall of the limiting rod 150. The retaining ring 151 fits into the bottom of the displacement plate 141, and the limiting rod 150 passes through the top of the displacement plate 141.

[0028] It is worth noting that the top of the support member 110 is fixedly connected to the fixing member 153, which is matched with the limiting rod 150, by bolts. The limiting rod 150 is fitted with a long spring that is matched with the fixing member 153. When the telescopic column 140 retracts, causing the displacement plate 141 to move upward and reset, the long spring uses its own elasticity to match the fixing ring 152, causing the limiting rod 150 to move upward and causing the cover 130 to reset.

[0029] It is worth noting that the cover 130 fits onto the top of the outer component 120. The cover 130 has a mating hole 132 machined on its exterior. The drive motor 142 uses a common motor, which consists of a housing, rotor, stator and shaft. The drive motor 142 is connected to a common external push-button switch via a power cord. The external push-button switch is powered by an external power source via a power cord. The shaft fits into the interior of the mating hole 132. The grinding part 143 is fixed to the bottom of the shaft with bolts.

[0030] In addition, the circuits, electronic components and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the internal structure and method.

[0031] Working principle: After the corrugated plate is placed in the positioning pit 101, the telescopic column 140 can be extended to move the displacement plate 141 downward. The grinding disc 144 then contacts the top of the corrugated plate. The drive motor 142 then drives the grinding component 143 to grind the top of the corrugated plate. During grinding, the water outlet 131, connected to an external water pipe, discharges water to the top of the corrugated plate to assist the grinding component 143 in grinding. When the displacement plate 141 moves downward, it abuts against the retaining ring 151 of the limiting rod 150, causing the cover 130 to move downward. The cover 130 then engages with the top of the outer component 120, thus blocking the water ejected by the rotating grinding component 143. The water then... The water from the cover 130 flows into the interior of the outer component 120, thus preventing water containing powder from being splashed out and contaminating other structures of the grinding device, facilitating the grinding operation of the wave plate; when the displacement plate 141 moves downward, the cover 130 moves downward as well. At this time, the limiting rod 150 cooperates with the displacement plate 141 to move downward, and then the limiting rod 150 also moves downward at the top of the support member 110. At this time, the limiting rod 150 can limit the cover 130 and the displacement plate 141 at the same time, making the displacement plate 141 and the cover 130 more stable when moving up and down, which can resist the torque of the drive motor 142 during operation, so that the telescopic column 140 can extend and retract stably.
