Abstract
Description
Technical Field
[0001] This utility model relates to the field of crystalline glass processing technology, and in particular to a crystalline glass ashtray polishing device. Background Technology
[0002] Crystal glass ashtrays are widely popular in the market due to their unique appearance and high-end feel. However, traditional polishing processes often suffer from low efficiency and poor surface finish, making it difficult to meet the production requirements of high-quality products. To solve these problems, improvements to polishing equipment have become the key to improving the quality and production efficiency of ashtrays.
[0003] However, in actual use, the following shortcomings still exist. For example, the existing polishing equipment for crystal glass ashtrays cannot achieve adaptive surface polishing, dust prevention, and convenient dust removal. The crystal glass of ashtrays usually has complex curved surfaces. Traditional polishing equipment uses fixed grinding discs or flat contact, which makes it difficult to fit the curved surface contours, resulting in uneven grinding of edges, corners, and other parts. Fixed grinding discs cannot cover complex curved surfaces at once, requiring multiple clamping and adjustment of the workpiece, resulting in a long processing cycle. In non-adaptive polishing, the contact pressure between the grinding disc and the glass curved surface is uneven. Excessive local pressure may cause the glass to crack or chip. Glass fragments and abrasive dust generated during the polishing process will diffuse into the working environment. Long-term inhalation of glass dust may damage the respiratory system of operators.
[0004] Therefore, this utility model proposes a crystalline glass ashtray polishing device to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a polishing device for crystalline glass ashtrays.
[0006] To achieve the above objectives, this utility model adopts the following technical solution: a polishing device for crystal glass ashtrays, including a support base, and further comprising:
[0007] A dustproof assembly includes a hydraulic push rod mounted on the top of a support base. The output end of the hydraulic push rod is connected to a movable frame, which is slidably connected to the support base. A cover is provided at the bottom of the movable frame. A box body is connected to the bottom of the support base near the cover, and a chassis is threaded to the bottom of the box body.
[0008] The polishing assembly includes a first drive motor mounted on a movable frame. The output end of the first drive motor is connected to a rotating block, which is rotatably connected to a box cover. A mounting base is slidably connected inside the rotating block. A grinding head is provided at the bottom of the mounting base. A telescopic spring is provided on the mounting base, and a spring sheet is provided on the side of the mounting base near the telescopic spring.
[0009] Furthermore, a first limiting block is connected to the bottom of the box lid, and a first limiting groove is provided on the side of the box body near the first limiting block, with the first limiting block disposed in the first limiting groove.
[0010] The beneficial effects of adopting the above-mentioned further solution are as follows: when the hydraulic push rod drives the moving frame to move down, the first limiting block at the bottom of the box cover is precisely embedded in the first limiting groove on the box body, ensuring that there is no misalignment when the box cover and the box body are closed, preventing dust leakage during the polishing process, while enhancing overall stability, avoiding vibration-induced sealing failure, keeping the box cover and the box body coaxial at all times, ensuring accurate alignment of the grinding head and the workpiece, and improving polishing precision.
[0011] Furthermore, one end of the telescopic spring is connected to the rotating block, and the other end of the telescopic spring is connected to the mounting base. One end of the spring sheet is connected to the rotating block, and the other end of the spring sheet is connected to the mounting base.
[0012] The beneficial effects of adopting the above-mentioned further solution are: the telescopic spring and the spring plate work together to allow the mounting base to float slightly within the rotating block. When the grinding head contacts the workpiece, the telescopic spring buffers the pressure, and the spring plate provides stability, avoiding rigid contact that could damage the glass surface, ensuring that the grinding head always fits the workpiece evenly, and improving polishing consistency.
[0013] Furthermore, a second limiting block is connected to the mounting base, and a second limiting groove is provided on the side of the rotating block near the second limiting block, and the second limiting block is slidably connected in the second limiting groove.
[0014] The beneficial effects of adopting the above-mentioned further solution are: the second limiting block slides along the second limiting groove of the rotating block, restricts the movement range of the mounting seat, prevents it from coming off or wobbling when rotating, ensures that the grinding head adapts to adjustment while maintaining the stability of its motion trajectory, avoids the grinding head from shifting due to centrifugal force, ensures uniform polishing force, and reduces the risk of scratches on the workpiece surface.
[0015] Furthermore, a clamping and positioning assembly is provided inside the box. The clamping and positioning assembly includes a fixed frame connected inside the box. A second drive motor is installed at the bottom of the fixed frame. The output end of the second drive motor is connected to a first rotating rod. A second rotating rod is rotatably connected to the first rotating rod. A moving block is rotatably connected to the second rotating rod.
[0016] The beneficial effects of adopting the above-mentioned further solution are: the second drive motor drives the first rotating rod to rotate, which in turn drives the second rotating rod to push the moving block to slide on the limit seat, so that the clamping plate clamps or releases the workpiece. The third limit groove constrains the movement path of the second rotating rod, ensuring smooth clamping action, realizing quick clamping, adapting to ashtrays of different sizes, and the clamping force is adjustable to avoid glass breakage due to overpressure.
[0017] Furthermore, a clamping plate is connected to the top of the movable block, a limiting seat is connected to the fixed frame, the movable block is slidably connected to the limiting seat, a third limiting groove is provided on the limiting seat, and the second rotating rod is slidably connected in the third limiting groove.
[0018] The beneficial effects of adopting the above-mentioned further solution are: the moving block slides linearly along the limiting seat, and its movement is precisely guided by the third limiting groove, ensuring that the clamping trajectory of the clamping plate is always perpendicular to the workpiece. The rigid support of the limiting seat prevents skewing during clamping, ensuring accurate positioning of the ashtray and avoiding displacement during polishing, thereby improving processing accuracy and repeatability.
[0019] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0020] In this invention, when the crystal glass ashtray polishing device is working, the hydraulic push rod drives the moving frame to slide along the support seat, causing the box cover to fall and close with the box body to form a dustproof cavity. In the polishing assembly, the first transmission motor drives the rotating block to rotate on the box cover, and the mounting seat rotates with the rotating block. Its bottom grinding head contacts the surface of the ashtray. When the grinding head encounters the convex and concave curved surface of the ashtray, the mounting seat slides and compresses the telescopic spring in the rotating block. The spring sheet provides elastic support, so that the grinding head adapts to fit the curved surface. The dust generated by polishing is sealed in the box body. The chassis can be threaded off for cleaning dust. Attached Figure Description

[0031] 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.
[0032] like Figure 1 - Figure 3 As shown, this embodiment provides a technical solution: a polishing device for crystal glass ashtrays, including a support base 1, and further comprising:
[0033] Dustproof component 2 includes a hydraulic push rod 21 installed on the top of the support base 1. The output end of the hydraulic push rod 21 is connected to a movable frame 22. The movable frame 22 is slidably connected to the support base 1. A box cover 23 is provided at the bottom of the movable frame 22. A box body 24 is connected to the bottom of the support base 1 near the box cover 23. A chassis 27 is threadedly connected to the bottom of the box body 24.
[0034] The polishing assembly 3 includes a first drive motor 31 mounted on a movable frame 22. The output end of the first drive motor 31 is connected to a rotating block 32, which is rotatably connected to the cover 23. A mounting base 33 is slidably connected inside the rotating block 32. A grinding head 34 is located at the bottom of the mounting base 33. A telescopic spring 35 is mounted on the mounting base 33, and a spring piece 36 is located on the side of the mounting base 33 near the telescopic spring 35. When this crystal glass ashtray polishing device is in operation, the hydraulic push rod 21 drives the movable frame 22 to slide along the support base 1. The lid 23 is lowered and closed with the body 24 to form a dustproof chamber. In the polishing assembly 3, the first drive motor 31 drives the rotating block 32 to rotate on the lid 23. The mounting base 33 rotates with the rotating block 32, and the bottom grinding head 34 contacts the surface of the ashtray. When the grinding head 34 encounters the convex and concave curved surface of the ashtray, the mounting base 33 slides and compresses the telescopic spring 35 in the rotating block 32. The spring sheet 36 provides elastic support, so that the grinding head 34 adapts to the curved surface. The dust generated by polishing is sealed in the body 24. The chassis 27 can be threaded off for cleaning dust.
[0035] The above solutions also have limitations when polishing crystal glass ashtrays. They cannot guarantee accurate ashtray positioning and prevent displacement during the polishing process. Figure 1 - Figure 5 As shown: The bottom of the cover 23 is connected to a first limiting block 25. The box body 24 has a first limiting groove 26 on the side near the first limiting block 25. The first limiting block 25 is set in the first limiting groove 26. When the hydraulic push rod 21 drives the moving frame 22 to move down, the first limiting block 25 at the bottom of the cover 23 is precisely embedded in the first limiting groove 26 on the box body 24, ensuring that there is no misalignment when the cover 23 and the box body 24 are closed, preventing dust leakage during the polishing process, while enhancing the overall stability, avoiding vibration that could cause the seal to fail, and keeping the cover 23 and the box body 24 coaxial at all times, ensuring that the grinding head 34 is accurately aligned with the workpiece and improving the polishing accuracy.
[0036] like Figure 3As shown, one end of the telescopic spring 35 is connected to the rotating block 32, and the other end is connected to the mounting base 33. One end of the spring 36 is connected to the rotating block 32, and the other end is connected to the mounting base 33. The telescopic spring 35 and the spring 36 work together to allow the mounting base 33 to float slightly within the rotating block 32. When the grinding head 34 contacts the workpiece, the telescopic spring 35 buffers the pressure, and the spring 36 provides stability, avoiding rigid contact that could damage the glass surface. This ensures that the grinding head 34 always fits evenly against the workpiece, improving polishing consistency. The mounting base 33 is connected to a second limiting block 37. A second limiting groove 38 is provided on the side of the rotating block 32 near the second limiting block 37. The second limiting block 37 is slidably connected in the second limiting groove 38. The second limiting block 37 slides along the second limiting groove 38 of the rotating block 32, limiting the movement range of the mounting base 33, preventing it from coming off or wobbling when rotating, ensuring that the grinding head 34 adapts to adjustment while maintaining the stability of its movement trajectory, avoiding the grinding head 34 from shifting due to centrifugal force, ensuring uniform polishing force, and reducing the risk of scratches on the workpiece surface.
[0037] like Figure 1 as well as Figure 4 - Figure 5 As shown, a clamping and positioning assembly 4 is provided inside the box body 24. The clamping and positioning assembly 4 includes a fixed frame 41 connected inside the box body 24. A second drive motor 42 is installed at the bottom of the fixed frame 41. The output end of the second drive motor 42 is connected to a first rotating rod 43. A second rotating rod 44 is rotatably connected to the first rotating rod 43. A moving block 45 is rotatably connected to the second rotating rod 44. The second drive motor 42 drives the first rotating rod 43 to rotate, which in turn drives the second rotating rod 44 to push the moving block 45 to slide on the limiting seat 47, so that the clamping plate 46 clamps or releases the workpiece. The third limiting groove 48 constrains the movement path of the second rotating rod 44 to ensure smooth clamping action and achieve rapid clamping. The quick-clamping mechanism is adaptable to ashtrays of different sizes, and the clamping force is adjustable to prevent glass breakage due to overpressure. The top of the moving block 45 is connected to a clamping plate 46, and a limiting seat 47 is connected to the fixed frame 41. The moving block 45 is slidably connected to the limiting seat 47, and a third limiting groove 48 is provided on the limiting seat 47. The second rotating rod 44 is slidably connected in the third limiting groove 48. The moving block 45 slides linearly along the limiting seat 47, and its movement is precisely guided by the third limiting groove 48 to ensure that the clamping trajectory of the clamping plate 46 is always perpendicular to the workpiece. The rigid support of the limiting seat 47 prevents skewing during clamping, ensures accurate positioning of the ashtray, avoids displacement during polishing, and thus improves processing accuracy and repeatability.
[0038] Working principle:
[0039] like Figure 1 - Figure 5As shown, firstly, the ashtray is placed on the clamping and positioning assembly 4 inside the box body 24. The second drive motor 42 starts, driving the first rotating rod 43 to rotate. This causes the second rotating rod 44 to be guided by the third limiting groove 48, pushing the moving block 45 to slide along the limiting seat 47. This allows the clamping plate 46 to precisely clamp the ashtray. The rigid support of the limiting seat 47 prevents tilting during clamping, ensuring accurate positioning of the ashtray and avoiding displacement during polishing. This enables rapid clamping and precise positioning of ashtrays of different sizes. After the workpiece is fixed, the dustproof assembly 2 starts operating. The hydraulic push rod 21 starts, driving the moving frame 22 to slide smoothly along the support seat 1. The box cover 23 then descends. At this time, the first limiting block 25 at the bottom of the box cover 23 is precisely embedded in the first limiting groove 26 on the box body 24, ensuring that the box cover 23 and the box body 24 are coaxially closed, forming a sealed dustproof chamber. This effectively prevents dust generated during polishing from spilling out, thus facilitating subsequent processing. To create a clean environment, once a sealed dustproof chamber is formed, the polishing assembly 3 begins operation. The first drive motor 31 drives the rotating block 32 to rotate on the cover 23, and the mounting base 33 rotates accordingly. The grinding head 34 at the bottom contacts the surface of the ashtray. During the polishing process, if the ashtray has a convex or concave surface, the mounting base 33 slides within the rotating block 32, compressing the telescopic spring 35. The spring sheet 36 provides elastic support simultaneously. The cooperation of the second limiting block 37 and the second limiting groove 38 limits the movement range of the mounting base 33, ensuring that the grinding head 34 can both adapt to and conform to the curved surface and maintain a stable movement trajectory. The telescopic spring 35 and the spring sheet 36 work together to buffer the pressure, avoiding rigid contact that could damage the glass, ensuring that the grinding head 34 always applies force evenly, improving polishing accuracy and consistency. The dust generated during polishing is sealed inside the box 24. After processing, the dust can be easily cleaned by disassembling the chassis 27, ensuring the continuous and efficient operation of the device.
[0040] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
