Description

Novel T-shaped groove sliding block

Technical Field

The invention belongs to the technical field of machining equipment, and particularly relates to a novel sliding block for a T-shaped groove.

Background

The T-shaped groove sliding block belongs to a tool clamp commonly used in machining or assembling, and particularly is widely used in the field of metallurgical machinery and during assembling in an assembly workshop and in the process of assembling and clamping mechanical equipment, the T-shaped groove sliding block is matched with a stud and a sizing block. A sliding block (detailed figure 1) for a common T (GB/T158-1996) type groove adopts a standard T type with a square section, the material is generally selected from a No. 45 quenched and tempered material with the hardness of HRC35, and the surface is subjected to oxidation treatment. The T-shaped groove sliding block is applied to a T-shaped groove (JB/ZQ4240-2006), and is often arranged in a T-shaped groove of a machine tool or an assembly ground beam (note: the T-shaped sliding block for an M24 screw is taken as an example in the following). In practice, before the conventional use T type groove uses the slider, must be with corresponding T type inslot iron fillings or foreign matter clean up, but no matter be the workstation of lathe or assemble the grade beam, T type groove often is blockked up by iron fillings or rubbish, foreign matter and is filled up, perhaps is covered by other equipment, and the slider is difficult to be put into the use, and the clearance is got up and is also very difficult, and is time-consuming again that the time is wasted to the time of taking a lot of manpower, material resources, increases intensity of labour, reduces work efficiency.

Disclosure of Invention

The invention aims to provide a novel sliding block for a T-shaped groove, which solves the problems that the T-shaped groove is often blocked and filled with scrap iron or garbage and foreign matters, the sliding block is difficult to use and the working efficiency is low due to difficult cleaning.

The technical scheme includes that the novel T-shaped groove sliding block comprises a base, the base is of a quadrangular structure, the bottom surface of the base is of a parallelogram structure, an acute angle of the parallelogram structure of the bottom surface is 52 degrees, an obtuse angle of the parallelogram structure of the bottom surface is a fillet, a clamping seat is fixedly connected to the upper bottom surface of the base, the clamping seat is of a quadrangular structure, the bottom surface of the clamping seat is of a diamond structure, and the obtuse angle of the clamping seat is a fillet. Two sides of the bottom surface of the clamping seat are parallel and equal to two short edges of the bottom surface of the base, and the other two sides of the clamping seat are superposed with the centers of two long edges of the bottom surface of the base.

The present invention is also characterized in that,

the center of the clamping seat is provided with a threaded hole.

The base and the clamping seat are integrally formed.

The beneficial effect of the invention is that,

1. when the T-shaped groove is used, the T-shaped groove is not required to be completely cleaned, the sliding block is used at any place to clean any place, and the sliding block is vertically loaded without searching a loading square hole. Manpower and material resources are reduced, time is saved, and efficiency is improved;

2. the novel T-shaped groove is very convenient to assemble and disassemble by the sliding block and can be carried out at any position of the T-shaped groove.

3. The novel sliding block for the T-shaped groove is reliable to use, when the screw is screwed down, the rotating trend of the sliding block for the T-shaped groove is always towards the clamping direction, and the rotating trend is opposite to the clamping direction when the screw is loosened, so that the novel sliding block for the T-shaped groove is safe and reliable.

Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

Novel slider for T type groove, as shown in fig. 3, including base 1, base 1 is quadrangular structure, and base 1's bottom surface is parallelogram structure, and the acute angle of bottom surface parallelogram structure is 52, and the obtuse angle of bottom surface parallelogram structure is the radius angle, and the bottom surface rigid coupling has cassette 2 on base 1, and cassette 2 is quadrangular structure, and the bottom surface of cassette 2 is diamond-shaped structure, and the obtuse angle of cassette 2 is the radius angle. Two side edges of the bottom surface of the clamping seat 2 are parallel and equal to two short edges of the bottom surface of the base 1, and the other two side edges are coincided with the centers of two long edges of the bottom surface of the base 1.

The center of the clamping seat 2 is provided with a threaded hole 3.

The base 1 and the card holder 2 are integrally formed.

As shown in fig. 3, taking the specification of a thread M24 with a groove width of 28mm as an example, the key of the novel slider for the T-shaped groove is to change two straight edges of the standard slider for the T-shaped groove shown in fig. 1 into a slope of 52 degrees to form a parallelogram, wherein the obtuse angle of the parallelogram structure on the bottom surface is rounded into R14, the upper part is a rhombus with the height consistent with the width of the T-shaped groove shown in fig. 2, and the obtuse angle of the rhombus is rounded into R14, so that the slider can rotate in the groove with the width of 28mm, and the rest part is consistent with the standard slider for the T-shaped groove.

In use, as shown in fig. 4, the two bevel edges of the T-shaped groove sliding block can be placed in the groove in parallel with the T-shaped groove at any position of the T-shaped groove, and then the screw rod is screwed in. When the screw is screwed, the sliding block for the T-shaped groove is driven to rotate clockwise under the action of friction force, as shown in fig. 5, until the other two sides of the diamond-shaped part of the sliding block for the T-shaped groove are clamped by the T-shaped groove, as shown in fig. 6, at the moment, the two wing edges of the sliding block for the T-shaped groove are also clamped in place and enter a working state. When the T-shaped groove is detached, the screw rod is loosened, the sliding block for the T-shaped groove can be driven by friction force to rotate along the anticlockwise direction, and when two bevel edges are parallel to the T-shaped groove, the sliding block for the T-shaped groove can be directly taken out.
