Description

Lengthened and reinforced woodworking bench saw protective cover

Technical Field

The invention relates to a table saw protective cover, in particular to a lengthened and reinforced woodworking table saw protective cover.

Background

The traditional table saw protective cover is mostly made of transparent plastics, is fragile in material and easy to be damaged by saw blades, is mostly used in the saw blades below 10 inches in application range, and has the problems that the end part of the protective cover swings greatly, the saw cover is inflexible to open and close and the like if the size of the saw blade is larger than 12 inches, so that uncertain factors are brought to safety.

Disclosure of Invention

In order to solve the problems, the invention provides an iron lengthened reinforced protective cover, and aims to effectively protect a large-size saw blade and effectively reinforce the tail part in the cutting process so as to solve the problems of large swinging, inflexibility and the like of the protective cover.

In order to achieve the purpose, the technical scheme of the application is as follows: a lengthened and reinforced woodworking table saw protective cover comprises a protective cover body, a bracket, a bearing, a sliding block a and a sliding block b; this end of body of safety cover is upwarp angle of rise structure, and safety cover body end connection has the support, has seted up rectangular hole on support upper portion, install the bearing in the rectangular hole, be equipped with slider an and slider b in the bearing both sides, slider an's boss supports and pushes up at bearing one side internal diameter terminal surface, slider b's boss supports and pushes up at bearing opposite side internal diameter terminal surface, bearing, slider an and slider b all are located safety cover body afterbody, and it has the connecting hole to open at safety cover body afterbody, and the bolt passes connecting hole, slider an, bearing, slider b, the connecting hole of safety cover body opposite side, gasket b and the lock nut of gasket an, safety cover body one side in proper order and is connected its fastening.

Furthermore, fit clearance of 0.05-0.1mm is kept between the step surfaces of the sliding block a and the sliding block b and the bracket.

Further, the material of safety cover body is iron.

Furthermore, the support is made of a bearing steel plate.

Furthermore, the thickness of the support is 0.8-1mm greater than that of the bearing.

Due to the adoption of the technical scheme, the invention can obtain the following technical effects:

1. prolong safety cover life: the safety cover is the iron material, and is more durable than the plastics material in the past. Because the fit clearance between the sliding block and the bracket is very small, the swing amount of the protective cover can be controlled to the maximum extent, and the protective cover can not be damaged by the saw blade.

2. Flexible operation, safety and reliability: because the tail part of the protective cover is connected by the bearing, the protective cover can freely slide up and down according to the thickness of the plate during cutting, and the operation is more flexible and reliable.

Drawings

FIG. 1 is a side view of an elongated, reinforced woodworking table saw guard;

FIG. 2 is a cross-sectional view A-A of FIG. 1;

FIG. 3 is an enlarged view of a portion of FIG. 2 at B;

the sequence numbers in the figures illustrate: 1. the protective cover comprises a protective cover body, 2 parts of a support, 3 parts of a sliding block b, 4 parts of a bearing, 5 parts of a bolt, 6 parts of a gasket a, 7 parts of a locknut, 8 parts of a sliding block a, 9 parts of a fit clearance and 10 parts of a step surface.

Detailed Description

The embodiments of the present invention are implemented on the premise of the technical solution of the present invention, and detailed embodiments and specific operation procedures are given, but the scope of the present invention is not limited to the following embodiments.

Example 1

The embodiment provides a lengthened and reinforced woodworking table saw protective cover, which comprises a protective cover body (1), a bracket (2), a sliding block b (3), a bearing (4), a bolt (5), a gasket a (6), a locknut (7), a sliding block a (8) and a gasket b; the protective cover body (1) is made of iron, the end part of the protective cover body is of an upwarp lifting angle structure, and the tail part of the protective cover body is provided with a connecting hole for fastening and connecting all the components through bolts (5). The support (2) is made of a bearing steel plate and aims to be fixed on a table saw and not to shake, the upper part of the support (2) is provided with a long hole for installing an ultrathin bearing (4), the thickness of the support is 0.8-1mm larger than that of the bearing, and two planes of the support are required to ensure higher smoothness and parallelism. The boss parts of the sliding blocks a (8) and the sliding blocks b (3) are respectively abutted against the inner diameter end face of the bearing (4), and meanwhile, the step faces of the two sliding blocks and the bracket (2) are kept in fit clearance of 0.05-0.1 mm. The outer sides of the two sliding blocks are wrapped by the tail portion of the protective cover body (1), and the sliding block a, the bearing and the sliding block b are connected and fastened between the two side walls of the protective cover body through the bolt (5), the gasket (6) and the locknut (7). Because the safety cover body extension, the oscillating quantity of afterbody subassembly clearance volume direct influence tip, consequently the clearance volume of two sliders of control and support can reduce the saw bit and directly harm the safety cover, simultaneously through the nimble rotation of bearing for the safety cover can freely promote from top to bottom, and cutting process is more smooth and easy safety.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, it should be noted that, for those skilled in the art, many modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
