Description

Technical Field

[0001] The invention relates to the technical field of dustproof equipment for polishing machines, and in particular to a dustproof structure for a transmission mechanism in a polishing machine. Background Art

[0002] Polishing machine is an electric tool, generally composed of basic components such as base, polishing disc, polishing fabric, polishing cover and cover. Polishing machine is widely used in mechanical parts, medical equipment, instrumentation, light industry, aerospace industry, automotive parts and other industries to achieve the purpose of chamfering, rounding, deburring, rust removal, and can also remove oxide scale and remove processing marks and other surface bright polishing. The transmission mechanism in the polishing machine will generate a lot of dust during operation. The polishing machines on the market are often large in size and complex in structure, which is inconvenient to use. During the polishing process, it is easy to generate flying dust, which will cause pollution to the surrounding environment of the transmission mechanism, and the cleaning process is more laborious; it will also affect the operation of the transmission mechanism of the polishing machine. Dust entering the transmission mechanism of the polishing machine will affect the polishing accuracy and even seriously reduce the service life of the polishing machine. Therefore, it is quite necessary to remove dust from the transmission mechanism during the use of the polishing machine. The dust prevention method commonly used in the prior art is to add a fixed dust baffle. However, for the movable structure in the grinding and polishing machine, the fixed dust baffle will inevitably affect the movement of the gears in the polishing machine. If a moving gap is reserved, it cannot meet the good dust prevention effect. It has great limitations and has an adverse effect on the service life of the overall equipment.

[0003] Patent application CN105058240A discloses a polishing machine with a dust hood, including a driving motor, a transmission box, and a polishing wheel. The driving motor drives the polishing wheel to rotate through the transmission box, and also includes a dust cover, a dust collecting chamber, and an exhaust fan. The dust cover is half-opened and arranged around the polishing wheel. A dust collecting port is arranged at the bottom of the dust cover. The dust collecting chamber is arranged at the bottom of the dust cover and is connected to the dust cover through the dust collecting port. A dust collecting bag is arranged in the dust collecting chamber. The bag opening of the dust collecting bag completely wraps the dust collecting port. The air inlet of the exhaust fan is connected to the dust collecting chamber. By adding a dust collecting chamber, an exhaust fan, and a dust collecting bag to an ordinary dust cover, dust can be absorbed and stored, and dust can be prevented from spreading again, so that the dust recovery rate is higher; however, the above structure collects dust through the dust collecting chamber, and cannot achieve the dustproof effect. Moreover, the structure is complicated and cannot achieve the dustproof effect. It is particularly not suitable for sealing protection when the gears in the polishing machine transmission mechanism have an appropriate swing amplitude. Summary of the invention

[0004] To solve the above problems, the object of the present invention is to provide a dust cover for a polishing machine transmission mechanism, which has a simple structure, is suitable for use in a polishing machine and can seal and protect the gears in the transmission mechanism.

[0005] Another object of the present invention is to provide a dust cover for a polishing machine transmission mechanism, which can meet the requirements of sealing and dustproofing of swinging gears in the transmission mechanism and has a good dustproof effect.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows.

[0007] The present invention provides a dust cover for a polishing machine transmission mechanism, characterized in that the dust cover comprises a first box body and a second box body, the first box body and the second box body are arranged side by side and enclosed internally to form a protective space for accommodating external gears; the first box body and the second box body are both sleeved on the gears, and both have through holes for accommodating the gear transmission shaft to pass through; the first box body and the second box body are respectively provided with a first notch and a second notch on the side walls, and the two are arranged side by side and adapted to each other so that the gears have appropriate space for swinging.

[0008] The second box body swings around the axis of the first box body and within the range of the first notch, and can be positioned by the edge of the first notch; the first box body and the second box body are adapted to the accommodated gears. In the present invention, the dust cover includes a first box body and a second box body, which has a simple structure, and can simplify the manufacturing process during production, thereby reducing the manufacturing cost; in the transmission mechanism of the polishing machine, the working gears are engaged with each other and will swing relative to each other, and the first box body and the second box body will swing with the working gears, which will not affect the normal operation of the gears in the polishing machine, and at the same time have a dustproof effect. The connection method of the first box body and the second box body in the present invention can be applied to the polishing machine and can seal and protect the rotating gears in the transmission mechanism.

[0009] Specifically, the first box body includes an upper horizontal plate, a cylindrical shell with a notch on one side, and a lower horizontal plate; the upper horizontal plate and the lower horizontal plate are respectively fixed to the top and bottom of the cylindrical shell, and form a cavity with the first notch. In practice, the first box body can be assembled by fixing the upper horizontal plate with other external components in the polishing machine.

[0010] Specifically, the structure also includes a flexible dustproof belt, which covers the outer surface of the first box body and the second box body and rotates with the first box body and the second box body. The setting of the flexible dustproof belt creates a closed space for the protective space formed by the first box body and the second box body, so that the dust cover has a good sealing and protective effect when in use; although the first box body and the second box body are respectively provided with a first notch and a second notch, the dustproof belt can effectively seal the above-mentioned notches, and form an effective seal in combination with the actual movement process. In addition, the setting of the flexible dustproof belt can stably place the first box body and the second box body side by side, reduce the space occupied by the combination of the first box body and the second box body, will not affect the setting of other components in the polishing machine, and can ensure that the first box body and the second box body can swing stably with each other.

[0011] Specifically, at least one side of the flexible dustproof belt is provided with a fastener, and the fastener is used to compress the dustproof belt, and the fastener passes through the upper horizontal plate and the lower horizontal plate in sequence and compresses the flexible dustproof belt at the edge of the first notch. Since the flexible dustproof belt will move with the first box body and the second box body when the transmission mechanism is working, the fastener is added to prevent the flexible dustproof belt from being offset or even falling off when the dust cover is working, and ensure that the flexible dustproof belt fits the first box body and the second box body when moving, ensuring a good sealing and dustproof protection effect.

[0012] Specifically, the upper horizontal plate and the lower horizontal plate are symmetrically provided with upper fixing holes and lower fixing holes of matching shapes and sizes, and the upper fixing holes and the lower fixing holes are both located on both sides of the first notch; the fasteners pass through the upper fixing holes and the lower fixing holes in sequence to press the flexible dustproof belt against the edge of the first notch. The opening of the fixing holes facilitates the installation of the fasteners.

[0013] Specifically, the perforations include a first circular hole and a second circular hole located on the upper horizontal plate and the lower horizontal plate, respectively, and the first circular hole and the second circular hole are matched in shape and size; the first circular hole and the second circular hole are stacked. The opening of the first circular hole and the second circular hole facilitates the installation between the gear and the parts connected to the gear in the transmission mechanism.

[0014] Specifically, a support ring is fixedly mounted on the second notch, and the support ring is located in the middle of the second notch and swings with the second notch. The support ring is provided to support the flexible dustproof belt to prevent the flexible dustproof belt from contacting the external gear installed in the first box body through the second notch during operation.

[0015] Specifically, the perforations further include a third circular hole and a fourth circular hole located on the upper and lower surfaces of the second box body, and the third circular hole and the fourth circular hole are staggered and parallel. The opening of the third circular hole and the fourth circular hole facilitates the installation between the gear and the transmission mechanism and the parts connected with the gear.

[0016] Compared with the prior art, the dust cover of the present invention has a simple structure, and the manufacturing process can be simplified during production, thereby reducing the manufacturing cost; the second box body swings around the first box body, and a protective space for accommodating external gears is formed inside the two. The first box body and the second box body are respectively provided with a first notch and a second notch. In the transmission mechanism of the polishing machine, the working gears are engaged with each other and will swing relative to each other. The first box body and the second box body will swing with the working gears, which will not affect the operation of the gears in the polishing machine and can also prevent dust. The connection method of the first box body and the second box body in the present invention can be applied to the polishing machine and can seal and protect the rotating and moving gears in the transmission mechanism.

[0021] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0022] To achieve the above objectives, the technical solution of the present invention is as follows.

[0023] See also Figure 1-4The present invention provides a dust cover for a polishing machine transmission mechanism, comprising a first box body 1 and a second box body 2, which are arranged side by side and enclosed inside to form a protective space for accommodating an external gear (not shown); the first box body 1 and the second box body 2 are both sleeved on a gear 3, and both have a through hole 0 for accommodating a gear transmission shaft (not shown); the first box body 1 and the second box body 2 are respectively provided with a first notch 11 and a second notch 21 on the side walls, and the two are arranged side by side and matched to each other, so that the gear 3 has an appropriate space for swinging. The second box body 2 swings around the axis of the first box body 1 and within the range of the first notch 11, and can be positioned by the edge of the first notch 11; the first box body 1 and the second box body 2 are matched with the accommodated gear 3.

[0024] The gear 3 includes a first gear 31, a second gear 32 and a third gear 33, and the first gear 31 and the third gear 33 are respectively located on both sides of the second gear 32 and respectively mesh with the second gear 32. The first gear 31 and the second gear 32 are located in the second box body, and the third gear 33 is located in the first box body 1.

[0025] In the transmission mechanism of the polishing machine, the first gear 31, the second gear 32 and the third gear 33 will all rotate during operation, and the first gear 31 and the second gear 32 have the same swing angle and swing direction, and the second gear 32 swings around the third gear 33.

The connection method of the first box body 1 and the second box body 2 in the present invention can be applied to the polishing machine and can seal and protect the rotating gear 3 in the transmission mechanism (not shown). In addition, since the second gear 32 and the third gear 33 in the polishing machine will engage and swing relative to each other, in order not to hinder the movement between the second gear 32 and the third gear 33 in the polishing machine, the first notch 11 and the second notch 21 are opened.

In practice, the first box body 1 can be assembled by fixing the upper horizontal plate 12 with other external components (not shown) in the polishing machine.

[0027] In this embodiment, the structure further includes a flexible dustproof belt (not shown), which covers the outer surfaces of the first box body 1 and the second box body 2 and rotates with the first box body 1 and the second box body 2. The provision of the flexible dustproof belt creates a closed space for the protective space formed by the first box body 1 and the second box body 2, so that the dust cover has a good sealing and protective effect when in use; although the first box body 1 and the second box body 2 are respectively provided with a first notch 11 and a second notch 21 on the side walls, the flexible dustproof belt can effectively seal the above-mentioned notches, and an effective seal is formed in combination with the actual movement process.
