Abstract

A turning clamp of a thin-wall part comprises a clamp disc. Three soft claws are respectively connected onto three soft claw bodies on the clamp disc through location grooves, and location faces are arranged on the soft claws. The turning clamp is simple in structure, low in manufacture cost, convenient in operation, accurate and reliable in part location, big in clamping area, even in stress, small in part deformation, high in production efficiency, low in manufacture cost, and applicable to mass manufacture of the thin-wall part.

Description

A kind of thin-walled parts turning clamp

Technical field

The utility model relates to a kind of machine tools, especially for the turning clamp of thin-walled parts.

Background technology

In electronic product transmitting tube, vacuum switch tube components, be that the nonferrous materials stamping parts of 0.3～3mm is main often, be size and the form and position tolerance that reaches product, also need inside and outside footpath of turning and sealing surface usually with wall thickness; Because of the part wall is thinner, intensity is lower, need use anchor clamps during turning; Commonly used a kind of be nut clamp; Be exactly with mandrel connect with main shaft or clamping on chuck, prepare the gap with part, with nut compress or top board hold out against the back turning; The 2nd, dabber clamp is exactly to take interference fit between mandrel and part, and part is pressed into behind the mandrel because of distortion is fixed on the mandrel, and positioning accuracy is high, and part deformation is little; The 3rd, the clamp ring anchor clamps are directly joined according to the part inside/outside and to be made cylindrical/endoporus, through fluting, make anchor clamps have adjustable elastic, utilize clamp ring to clamp part during use, and are simple in structure, easy to use.

In three kinds of existing anchor clamps, first is poor with the third positioning accuracy, can not satisfy the required precision of part processing, though second kind has high orientation precision; But complex structure, cost is high, and the part loading, unloading are difficult for during use; Production efficiency is low, and production cost is high, unsuitable small batch production.

The utility model content

The utility model aims to provide a kind of anchor clamps that are used for thin-walled parts machining, part accurate positioning, reliable, and the clamping area is big, and it is stressed that evenly part is easy to loading and unloading, and is easy to operate, and production efficiency is high, and the thin-walled parts that is suitable for many specifications, many kinds is produced in batches.

A kind of thin-walled parts turning clamp comprises chuck, and three soft pawls are connected on three soft corpus unguis on the chuck through locating slot, on the soft pawl locating surface are arranged.

Said locating surface is an inner surface.

Said locating surface is an outer surface.

Said locating surface is interior circle and end face.

Said locating surface is cylindrical and end face.

The preparation material of said soft pawl is duralumin, brass, bakelite, A3 steel or 45# steel.

The utility model is simple in structure, and low cost of manufacture is easy to operate, part accurate positioning, reliable, and the clamping area is big, and it is stressed that evenly part deformation is little, and production efficiency is high, and processing cost is low, is suitable for the batch machining of thin-walled parts.

Among the figure: 1-chuck, the soft corpus unguis of 2-, 3-screw, the soft pawl of 4-, 5-part.

The specific embodiment

As shown in the figure, the utility model thin-walled parts turning clamp comprises that 1, three soft pawl 4 of chuck is installed in respectively on three soft corpus unguis 2 on the chuck through locating slot, and is fixing with screw 3, on the soft pawl 4 locating surface arranged.

The locating surface of soft pawl 4 can be inner surface or outer surface, can also be interior circle and end face integrated positioning, or cylindrical and end face integrated positioning.The preparation material of soft pawl 4 can be duralumin, brass, bakelite, A3 steel or 45# steel.

The inner surface of processing parts and end face, the inner surface location of available soft pawl 4, as shown in Figure 1; The outer surface of processing parts and end face, the outer surface location of available soft pawl 4, as shown in Figure 2; The interior circle and the end face of processing parts, the interior circle of available soft pawl 4 and end face integrated positioning are like Figure 10,11,12, shown in 13; The cylindrical of processing parts and end face, the cylindrical of available soft pawl 4 and end face location are like Figure 14,15,16, shown in 17.

Soft pawl 4 utilizes locating slot and the screw location connection and fixing on the soft corpus unguis 2, joins car according to accessory size during use, and repetitive positioning accuracy can reach 0.01～0.03 millimeter.Soft corpus unguis can directly be processed with the groove milling of a pole face work, like Fig. 1,2,3, shown in 4; Also can directly process, like Fig. 5,6,10,11,12,13,14, shown in 15 with the groove milling of three pole face work; Perhaps process, like Figure 16, shown in 17 with the groove milling of hexagonal rod face work.It is convenient to make, and cost is low.

The utility model not only can have on the lathe, also is applied on the lathes such as milling machine, drilling machine, and highly versatile is specially adapted to the machining of punching parts of thin-walled and abnormity.

Certainly; The utility model also can have other various embodiments; Under the situation that does not deviate from the utility model spirit and essence thereof; Those of ordinary skill in the art can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the utility model.
