Abstract

A tooling fixture for manufacturing a clamping block comprises a base, wherein a V-shaped fixed block for placing the clamping block is mounted on the base, a V-shaped groove is formed in the middle of the V-shaped fixed block, and a positioning pin for positioning the clamping block is arranged in the V-shaped groove; and pressure plates for tightly pressing and fixing the clamping block are connected to the outer sides of two end ports of the V-shaped fixed block mounted on the base. The tooling fixture for manufacturing the clamping block has the advantages as follows: the structure is simple; the use is convenient; the manufacturing cost is low; one time of clamping positioning can achieve repetitive processing of parts, so as to save a large amount of time for alignment and improve processing efficiency and processing precision of the parts; and in addition, requirement on skill of operators is low. The tooling fixture for manufacturing the clamping block is particularly suitable for process of mass production.

Description

A kind of frock clamp for the clamp making

Technical field

The utility model relates to a kind of frock clamp for the clamp making.

Background technology

Clamp in the Digit Control Machine Tool, as shown in Figure 1, the demand of this part is a lot, its main feature be in the external diameter profile, need open an arc groove 1 ', and this arc groove 1 ' required distance is arranged with end face, though the part profile is simple, because this part has internal control, wall is thinner, the not science of clamping location, its deflection is increased, make on drilling machine difficulty of processing bigger, clamping is incorrect, can produce distortion, do not reach the specification requirement after the processing, and working (machining) efficiency is very low, process-cycle and cost are strengthened, and the industrial grade requirement to the processor is also higher, and the input of enterprise is increased, and is very uneconomical.

Summary of the invention

The purpose of this utility model is to provide a kind of can locate, clamp convenience, not yielding to clamp fast and accurately fast, and can significantly save a large amount of centering positioning times, shorten process time significantly, improved the frock clamp that clamp is made that is used for of operating efficiency.

For reaching the goal of the invention the technical solution adopted in the utility model be:

A kind of frock clamp for the clamp making, it is characterized in that: comprise a base, be equipped with on the described base for the fixedly V-block of putting clamp, the centre of described fixedly V-block is a V-type groove, is provided with the alignment pin of clamp being located usefulness in the described V-type groove; The two-port outside at fixing V-block on the described base also is connected with the pressing plate that clamp is fixed.

Further, have the notch that withdrawing is used on the side of described fixedly V-block.

Further, described pressing plate is connected on base by double threaded screw and nut.

Further, described base is a flat base.

The course of work of the present utility model is as follows:

1, fixedly V-block, pressing plate correctly are installed on the base, alignment pin correctly are installed in the V-type groove of fixing V-block, make the position of each respective element reach corresponding specification requirement.

2, put into the T type groove of lathe with T type nut, frock clamp for the clamp making described in the utility model correctly is installed in the workbench of lathe, play table with dial gauge and measure at two measuring basis faces of the frock clamp of making for clamp described in the utility model, make it reach vertical, horizontal perpendicularity requirement.

3, after the frock clamp of making for clamp described in the utility model installs, as long as clamp is put into the V-type groove, make an end face of clamp prop up alignment pin in the V-type groove, screw pressing plate with nut again and compress clamp and get final product.

4, with process tool the arc groove to be milled of clamp being carried out milling gets final product.To be processed finishing unclamped nut, takes out clamp, and whole process has just been finished.

5, repeat above-mentioned steps 3 and step 4, can operate next part, so just can finish the production in enormous quantities of clamp.

The beneficial effects of the utility model: simple in structure, easy to use, cost of manufacture is cheap, and a clamping location, can repeat processing parts, save the time of centering in a large number, improved working (machining) efficiency, and improved the machining accuracy of part, simultaneously, less demanding to operator's technical ability.The spy is applicable in the large batch of production process.

The specific embodiment

Come the utility model is further specified below in conjunction with specific embodiment, but the utility model is not confined to these specific embodiment.One skilled in the art would recognize that the utility model contained in claims scope all alternatives, improvement project and the equivalents that may comprise.

With reference to Fig. 2-5, a kind of frock clamp for the clamp making comprises a base 1, is equipped with on the described base 1 for the fixedly V-block 2 of putting clamp 7, the centre of described fixedly V-block 2 is V-type grooves 21, is provided with the alignment pin 3 with clamp 7 location usefulness in the described V-type groove 21; The two-port outside at fixing V-block 2 on the described base 1 also is connected with the pressing plate 4 that clamp 7 is fixed.

Have the notch 22 that withdrawing is used on one side of described fixedly V-block 2.

Described pressing plate 4 is connected on base 1 by double threaded screw 6 and nut 5.

Described base 1 is a flat base.

The course of work of the present utility model is as follows:

1, fixedly V-block 2, pressing plate 4 correctly are installed on the base 1, alignment pin 3 correctly are installed in the V-type groove 21 of fixing V-block 2, make the position of each respective element reach corresponding specification requirement.

2, put into the T type groove 10 of lathe with T type nut, frock clamp for the clamp making described in the utility model correctly is installed in the workbench 9 of lathe, play table with dial gauge and measure at two measuring basis faces of the frock clamp of making for clamp described in the utility model, make it reach vertical, horizontal perpendicularity requirement.

3, after the frock clamp of making for clamp described in the utility model installs, as long as clamp 7 is put into V-type groove 22, make an end face of clamp 7 prop up alignment pin 3 in the V-type groove 22, screw pressing plate 4 with nut 5 again and compress clamp 7 and get final product.

4, carrying out milling with the arc groove to be milled of 8 pairs of clamps 7 of process tool gets final product.To be processed finishing unclamped nut 5, takes out clamp 7, and whole process has just been finished.
