Abstract

The utility model relates to swinging clamp forceps of a pipe fitting numerical-control drill machine. One side of the clamp forceps is provided with a V-shaped notch, the middle of the other side of the clamp forceps is provided with a pivot shaft hole, and the clamp forceps are pivoted with a clamp block base via a round shaft. The swinging clamp forceps capable of swinging around a pivot shaft can be adaptable to adjusting various bent or deformed pipe fittings in a self-adaption adjustment form, and can firmly clamp processed pipe fittings so as to realize safe and stable drilling operation, thereby sufficiently increasing drilling quality.

Description

The oscillating grippers of pipe fitting numerical control drilling machine

Technical field

The utility model relates to field of machine tool equipment, in particular for the numerical control drilling machine of processing pipe part areole.

Background technology

Pipe parts such as boiler header need be processed a lot of through holes or blind hole on the tube wall of pipe, the pipe fitting numerical control drilling machine of the applicant's research and development is clamped in the two ends of pipe fitting on the workbench by rotating chuck, the drilling platform movably is arranged on the workbench, referring to Fig. 1, drilling platform 4 is provided with the clamp assemblies and the drill unit assembly of processing pipe fitting, clamp assemblies comprises first grip block 1 and second grip block 3 that is arranged on pipe fitting 2 both sides, can be along the relative motion of pipe fitting horizontal diameter direction, hold tightly or loosen pipe fitting; The drill unit assembly comprises drill bit, by drilling main shaft and motor and transmission mechanism drives and feeding, adopts for example unit head assembly of general NC drilling machine or CNC milling machine of prior art, after clamp assemblies is fixing pipe fitting is carried out outer wall boring and processes.

But when reality is used, because axially the linearity of longer pipe spare central shaft is difficult to guarantee, comparatively significantly pipe fitting central shaft bending may appear, when perhaps the pipe fitting cross section deforms, the stationary clamp of first grip block 1 and second grip block, 3 top one is the clamping pipe fitting well, drilling adds the man-hour Workpiece vibration can damage drill bit and equipment, has influenced the quality of machining hole; And rigid clamping meeting damage pipe fitting by force, also the resistance that clamping can be subjected to is transferred to line slideway 5, the gear 7 and tooth bar 6 of bottom, thus the accurate reception and registration guider of damage causes the damage of equipment.

The utility model content

The applicant is at the effective clamping pipe fitting of the tube wall clamp of above-mentioned existing numerical control drilling machine rigidity, cause the shortcomings such as crudy difference in the damage of equipment and pipe fitting, hole, a kind of oscillating grippers of the pipe fitting numerical control drilling machine that can adjust flexibly is provided, and it is rational in infrastructure, clamping effect firm stable.

The technical scheme that the utility model adopted is as follows:

A kind of oscillating grippers of pipe fitting numerical control drilling machine, described clamp one side is provided with V-notch, and the opposite side middle part is provided with pivot hole, articulates by circular shaft and clamp pedestal.

The utility model adopts can be around the clamp structure of pivot swinging, and the self adaptation adjustment is suitable for the pipe fitting of various bendings or distortion, the processed pipe fitting of clamping that can be firm so that safety and stability carry out the drilling operation, thereby fully improved the drilling quality.

Description of drawings

Fig. 1 is the front view of numerical control drilling machine sliding platform;

Fig. 2 is a front view of the present utility model, is A place enlarged drawing among Fig. 1.

The specific embodiment

Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described.

As shown in Figure 2, the V-type clamp 9 that the utility model first grip block 1 and second grip block, 3 tops are provided with is an individual part, clamp 9 one sides are provided with V-notch, the opposite side middle part is provided with pivot hole, articulate by bearing pin 8 and clamp pedestal 10, can do certain angle swing rotation around bearing pin 8, thereby when clamping, can do adaptive flexible adjustment according to the outside wall surface shape that is held pipe fitting, more effectively stable clamping is carried out in the circular section, thus prevent rigid structure can not the self adaptation adjustment the effective situation of clamping or rigid clamping damage pipe fitting.

More than describing is to explanation of the present utility model, is not the qualification to utility model, and the utility model institute restricted portion is referring to claim, and under the situation of spirit of the present utility model, the utility model can be done any type of modification.

Claims

1. the oscillating grippers of a pipe fitting numerical control drilling machine, it is characterized in that: described clamp one side is provided with V-notch, and the opposite side middle part is provided with pivot hole, by circular shaft and the pivot joint of clamp pedestal.
