Description

Technical Field

[0001] The utility model belongs to the technical field of machining equipment, in particular to a saw blade metal shavings sweeping device. Background Art

[0002] In the valve block production process, it is necessary to cut the large metal block into small metal blocks, then drill holes in the small metal blocks, and then perform subsequent processing to form the valve block. When cutting the metal block, a vertical sawing machine is usually used for cutting. During the cutting process of the vertical sawing machine, its saw blade is mounted on a pair of drive wheels, and the drive wheels will drive the saw blade to rotate to complete the cutting. A limit clamp is provided on one side of the saw blade, and the limit clamp is fixed to the sawing machine body through a fixing rod. When the saw blade is installed, it will be placed in the limit clamp to prevent the saw blade from shaking left and right. When the saw blade rotates and cuts the metal block, metal shavings may adhere to both sides of the saw blade and bring the metal shavings into the drive wheel, making it difficult to clean the metal shavings and even affecting the coordination between the drive wheel and the saw blade. Therefore, further improvement is necessary. Utility Model Content

DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings, but the embodiments described in the utility model are only part of the embodiments of the utility model, rather than all the embodiments.

[0025] The present application embodiment provides a saw blade metal shavings cleaning device, such as Figure 1-Figure 5 As shown, it includes a U-shaped buckle 1, a connecting rod 3, a dust removal brush 4, etc.

[0026] Specifically, the U-shaped buckle 1 includes a bottom plate 101 and a pair of fixed plates 102 vertically arranged at both ends of the bottom plate 101. A threaded hole is opened on a fixed plate 102 at the rear end of the bottom plate 101, and a fixing screw 2 is threadedly connected in the threaded hole. A pair of connecting rods 3 are hinged at one end to the two ends of a fixed plate 102 at the front end of the bottom plate 101, and the axial direction of the hinge is parallel to the length direction of the fixed plate 102. A support rod 301 is provided at both ends of a fixed plate 102 at the front end of the bottom plate 101. When the connecting rod 3 When rotating outward until it abuts against the support rod 301, the connecting rod 3 is perpendicular to the fixed plate 102, and the dust removal brush 4 is a pair, which is hinged to the other end of a pair of connecting rods 3 through a hinge shaft 401 respectively, and the axial direction of the hinge shaft 401 is perpendicular to the fixed plate 102. The other end of the connecting rod 3 is provided with a first stop block 302. When the dust removal brush 4 rotates inward until it abuts against the first stop block 302, the length direction of the dust removal brush 4 is parallel to the length direction of the fixed plate 102, and the distance between the bristles of the pair of dust removal brushes 4 is less than the thickness of the saw blade.

[0027] During actual use, the U-shaped buckle 1 is put on the fixed rod connected to the limit clamp, and then the screw is turned to fix the U-shaped buckle 1 to the fixed rod, so that a fixed plate 102 at the front end of the base plate 101 faces the saw blade, and the connecting rod 3 is rotated outward, and then the dust removal brush 4 is rotated inward, so that the bristles of a pair of dust removal brushes 4 respectively abut against the two sides of the saw blade. When the saw blade rotates upward, the bristles can brush out metal chips adhered to the saw blade to prevent the metal chips from entering the drive wheel and preventing it from affecting the coordination between the drive wheel and the saw blade.

[0028] Preferably, see Figure 3A first limiting hole 402 is formed on the side of the hinge shaft 401, and a second limiting hole 403 matching the first limiting hole 402 is formed on the dust removal brush 4. When the dust removal brush 4 rotates inward to abut against the first stopper 302, the first limiting hole 402 is connected to the second limiting hole 403. After the device is installed, a pin can be inserted into the first limiting hole 402 and the second limiting hole 403 to fix the dust removal brush 4 to prevent the dust removal brush 4 from rotating upward under the friction of the saw blade.

[0029] Preferably, see Figure 1 , Figure 2 , Figure 5 A pair of connecting plates 5 are vertically provided on the outward side of a fixed plate 102 at the rear end of the bottom plate 101. Vertical slide grooves 501 are provided on the connecting plates 5. A slide plate 6 is slidably connected in the vertical slide groove 501, and the two ends of the slide plate 6 respectively pass through two vertical slide grooves 501 to connect with a pair of cleaning combs 7. The comb teeth 701 of the cleaning comb 7 are arranged outward and perpendicular to the connecting plate 5. When the connecting rod 3 is rotated inward to be perpendicular to the fixed plate 102, and the bristles of the dust removal brush 4 are facing downward, the comb teeth 701 of the cleaning comb 7 are in the bristles. After the dust removal brush 4 has been sweeping away metal chips for a certain period of time, a lot of metal chips will adhere to it, which will affect the removal of the metal chips on the saw blade. At this time, the connecting rod 3 can be rotated inward, and the bristles of the dust removal brush 4 can be facing downward, so that the comb teeth 701 of the cleaning comb 7 are in the bristles, and then the slide plate 6 can be moved up and down to drive the cleaning comb 7 to move, so as to remove the metal chips adhered to the dust removal brush 4. For details, refer to Figure 4 A second stopper 303 is provided on both sides of a fixed plate 102 at the rear end of the bottom plate 101. When the connecting rod 3 rotates inward to abut against the second stopper 303, the connecting rod 3 is perpendicular to the fixed plate 102, which facilitates the alignment of the dust removal brush 4 and the cleaning comb 7.

[0030] For details, see Figure 5 , a guide rod is vertically arranged in the vertical slide groove 501, and the slide plate 6 is slidably connected to the guide rod. The guide rod can limit the moving direction of the slide plate 6, thereby improving the stability of the slide plate 6 moving up and down. More specifically, a spring 502 is arranged on the outer sleeve of the guide rod, the bottom of the spring 502 is connected to the guide rod, and the top of the spring 502 is connected to the slide plate 6. When the spring 502 is in a natural state, the slide plate 6 is at the top of the vertical slide groove 501. After the spring 502 is arranged, after the slide plate 6 is pressed downward, the slide plate 6 will automatically reset under the elastic force of the spring 502, so as to facilitate the next cleaning of the dust removal brush 4.

[0031] The above are only some of the embodiments listed in this application and are not intended to limit this application.
