Preferably, the bottom end of the sliding block is provided with an anti-slip layer for increasing friction.

Preferably, the limiting convex strip is of a semi-cylindrical shape.

Preferably, the surface of the limiting convex strip is attached with a layer of anti-slip soft rubber layer.

Preferably, the cross section of the fixing groove is in the shape of a right triangle, and the right angle is located at the lower end of the fixing groove.

Preferably, the cross section of the fixing groove is in a right-angle or obtuse-angle triangle shape, and the right angle or the obtuse angle is located at the lower middle position of the formed triangle.

The utility model has the advantages that: 1) the utility model discloses a set up the fixed slot that the cross-section is triangle-shaped on the tool body to provide the basis for the fixed of triangular prism, set up spacing sand grip on one of them inclined plane of fixed slot, can realize the card of the triangular prism of putting into the fixed slot and fix; and after one side wall of the triangular prism is attached to the inclined plane on one side of the fixed groove without the limit convex strip, the position of the limit convex strip is adjusted up and down along the other inclined plane, so that various triangular prisms with different included angles can be clamped and fixed, and the application range is wide.

2) The setting of fixed slot bottom escape canal groove on the tool body can prevent promptly that the closed angle of waiting to process triangular prism from touching anchor clamps and damaging or wholly produce crooked, can play the effect of drainage when lapping and throwing again.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

A fixed jig for polishing a triangular prism is shown in figures 1 to 5 and comprises a jig body 1, wherein a plurality of fixing grooves 2 with triangular sections are formed in the jig body 1, a horizontal limiting convex strip 3 is arranged on one inclined plane of each fixing groove 2, and the limiting convex strips are tightly attached to the surface of the inclined plane and are connected with the inclined plane in a sliding mode up and down. Specifically, on the fixed slot 2 was equipped with the inclined plane of spacing sand grip 3, follow the inclined plane is equipped with spout 5 from the top down, be fixed with on the spacing sand grip 3 with the slider 6 of spout 5 looks adaptation.

When fixing triangular prism 101, guaranteeing to wait to throw the face and polish the condition up of triangular prism 101, glue one of them inclined plane of triangular prism 101 to the inclined plane that is not equipped with spacing sand grip 3 of fixed slot 2 on, then slide adjusting spacing sand grip 3, contradict the another side of triangular prism 101 until spacing sand grip 3, and then realize triangular prism 101 fixed.

In this embodiment, the bottom end of the fixing groove 2 is opened with a drainage groove 4 along the opening direction. The drainage groove 4 can prevent the sharp corner of the triangular prism 101 to be processed from touching the fixture and being damaged or being inclined as a whole, and can play a role in draining water when the triangular prism 101 is ground and polished, thereby achieving multiple purposes.

In this embodiment, the bottom end of the sliding block 6 and the bottom of the sliding chute 5 (not shown) are both provided with an anti-slip layer 61 for increasing friction, and the anti-slip layer 61 may be specifically an anti-slip rubber or an anti-slip mat. Set up like this, can prevent that spacing sand grip 3 from removing at will, avoid spacing sand grip 3 to take place unexpected removal after conflicting triangular prism 101.

In this embodiment, the limiting convex strip 3 is a semi-cylindrical shape, the plane portion of the limiting convex strip is closely attached to the inclined surface of the fixing groove 2, and the arc portion of the limiting convex strip protrudes into the fixing groove 2. Like this when the triangular prism 101 of different contained angles contradicts in spacing sand grip 3 different positions, the contact surface is all comparatively level and smooth, avoids causing the damage to triangular prism 101.

In this embodiment, the surface of the limiting convex strip 3 is attached with a layer of anti-slip rubber layer 31, which can increase the friction between the triangular prism 101 and the limiting convex strip 3, avoid rigid contact, and protect the triangular prism 101.

In this embodiment, the cross section of the fixing groove 2 is a right triangle, and the right angle is located at the lower end of the fixing groove 2.

In the present embodiment, the cross section of the fixing groove 2 is a right-angled or obtuse-angled triangle, and the right-angled or obtuse-angled is located at the lower middle position of the formed triangle.

The above embodiments are only used for illustrating the present invention, and not for limiting the present invention, and those skilled in the relevant technical field can make various changes and modifications without departing from the spirit and scope of the present invention, so that all equivalent technical solutions also belong to the scope of the present invention, and the protection scope of the present invention should be defined by the claims.
