Abstract

The utility model discloses a handle of a knife chuck installs be used for the centre gripping handle of a knife in the tool magazine, include the main part and provide respectively in the two card arm of main part both sides that card arm one end is articulated mutually with main part one end, the other end forms the jack catch along the opposite side that the main part extended to the main part, and two jack catch intermediate formation one is used for the movable draw -in groove of handle of a knife, also is equipped with and blocks the spring that the arm is connected mutually in the middle part of the main part, and elastic shrinkage power is exerted to a calorie arm to the spring to with the handle of a knife centre gripping in the activity in the draw -in groove. This handle of a knife chuck's spring is connected with the middle part of card arm, and the card arm is kept away from jack catch one end and is rotated with the main part and be connected, just so can guide to the atress and sell hub connection department to the atress is little when making the jack catch with the handle of a knife contact, difficult fracture, so card arm material hardness does not have very high requirement, the card arm can adopt plastics for example nylon manufacturing. Simultaneously, because the card arm centre gripping that the handle of a knife was held through two adoption springs to the atress is more even, the handle of a knife can be steadily by the centre gripping and be difficult to take place the skew.

Description

Handle of a knife chuck

Technical field

The utility model relates to tool magazine accessory, particularly a kind of handle of a knife chuck.

Background technology

Tool magazine system is to provide storage cutter required in automation process and a kind of device of tool changing demand; Its automatic tool changer and the tool magazine of much knives tool can be stored; Change tradition with the artificially main mode of production.By the control of computer program, various different process requirements can be completed, as milling, boring, bore hole, tapping etc.Significantly shorten processing time-histories, reduce production cost; This is the maximum feature of tool magazine system.

The development of tool magazine has in recent years surmounted its role for toolroom machine accessory, develops the product meeting the concepts such as toolroom machine high accuracy, high-effect, high-reliability and multiplex's compound in its distinctive technical field.The quality of its product quality, is related to the overall efficiency performance of toolroom machine.

The capacity of tool magazine, layout, for different toolroom machines, its form is also different, according to capacity, the external form of tool magazine with get cutter mode and generally can be divided into bamboo hat type tool holder, disc type tool magazine and chain-type tool magazine.

Handle of a knife is generally held in tool magazine by handle of a knife gripper chuck.Take for convenience of toolroom machine or place handle of a knife, handle of a knife chuck generally adopts the method for resilient clamp.Shown in Fig. 1 is the handle of a knife chuck relatively commonly used in the market.As shown in the figure, spring marble A is provided with in the draw-in groove of this handle of a knife chuck.When handle of a knife being put into draw-in groove and being inner, spring marble A applies pressure to the outer wall of handle of a knife, thus is fixed in draw-in groove by handle of a knife.But the stressed of this handle of a knife chuck is that point is stressed, especially the necessary perforate mounting spring pellet in draw-in groove both sides, when material hardness is inadequate, easily rupture in draw-in groove both sides, so the higher metal of hardness or alloy must be used to manufacture, simultaneously because handle of a knife both sides in draw-in groove are stressed, be easy to, because of both sides discontinuity, cause handle of a knife to offset, thus affect the normal work of tool magazine.

Utility model content

The purpose of this utility model is to provide a kind of handle of a knife chuck.

According to an aspect of the present utility model, provide a kind of handle of a knife chuck, be arranged in tool magazine for clamping handle of a knife, comprise main body and be arranged at two snap arm of main body both sides respectively, snap arm one end and main body one end are hinged, and the opposite side that the other end extends to main body along main body forms claw, a movable clamp groove for handle of a knife is formed in the middle of two claws, also be provided with the spring be connected with snap arm in the middle part of main body, spring applies elastic contractile force to snap arm, thus is clamped in movable clamp groove by handle of a knife.

Adopt the handle of a knife chuck of above technical scheme, spring is connected with the middle part of snap arm, snap arm is connected with body rotation away from claw one end, so just can guide to pinned connection place by stressed, thus it is not quite stressed when claw is contacted with handle of a knife, not easy fracture, so snap arm material hardness does not have very high requirement, snap arm can adopt plastics such as nylon to manufacture.Meanwhile, due to the snap arm clamping that handle of a knife adopts spring to hold by two, thus stressed more even, and handle of a knife stably can be less likely to occur skew by clamping.

In some embodiments, claw top is provided with card bead, and card bead and claw are rotationally connected and freely can rotate in claw.Thus, the clamping of handle of a knife is more smooth.

In some embodiments, the center of card bead has card bead bearing pin, and card bead bearing pin is connected with claw.Thus, the installation and maintenance of card bead is convenient.

In some embodiments, both ends of the spring is connected with two snap arm respectively.Two snap arm are connected by same spring, can make to be clamped handle of a knife both sides stressed more even, thus handle of a knife can not be offset.

Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model is described in further detail.

Fig. 2 to Fig. 4 show schematically show the handle of a knife chuck according to a kind of embodiment of the present utility model.This handle of a knife chuck 1 is arranged in circular tool magazine for clamping handle of a knife 2.

As shown in the figure, this device comprises main body 11 and is arranged at two snap arm 12 of main body 11 both sides respectively.Wherein, snap arm 12 one end is hinged by snap arm bearing pin 121 and main body 11 one end, and the opposite side that the other end extends to main body 11 along main body 11 forms claw 122.

A movable clamp groove 14 for handle of a knife 2 is formed in the middle of two claws 122.

Claw 122 top is provided with card bead 13, and the center of card bead 13 has card bead bearing pin 131, and card bead bearing pin 131 is connected with claw.Card bead 13 freely can be rotated in claw 122.The clamping of handle of a knife 2 is more smooth thus.

The spring 15 be connected with snap arm 12 is also provided with in the middle part of main body 11.Spring 15 two ends are connected with the middle part of two snap arm 12 respectively.Spring 15 pairs of snap arm 12 apply elastic contractile force, thus are clamped in movable clamp groove 14 by handle of a knife 2.Two snap arm 12 are connected by same spring 15, can make to be clamped handle of a knife both sides stressed more even, thus handle of a knife can not be offset.

Adopt the handle of a knife chuck of above technical scheme, spring 15 is connected with the middle part of snap arm 12, snap arm 12 is rotationally connected away from claw 122 one end and main body 11, so just can guide to pinned connection place by stressed, thus it is not quite stressed when claw 122 is contacted with handle of a knife 2, not easy fracture, so snap arm 12 material hardness does not have very high requirement, snap arm 12 can adopt plastics such as nylon to manufacture.Meanwhile, because handle of a knife 2 is clamped by the snap arm 12 that two adopt spring 15 to hold, thus stressed more even, and handle of a knife 2 stably can be less likely to occur skew by clamping.

Above-described is only embodiments more of the present utility model.For the person of ordinary skill of the art, under the prerequisite not departing from the utility model creation design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
