Embodiment 1

[0020] like figure 1 , a pistol drill clamping mechanism suitable for milling holes provided by the present invention includes two hoop-shaped hoop parts 7, a second sliding seat 6, a slider 3 and a base 1, and the base 1 is also The first sliding seat 2 is provided, and the hoop parts 7 are parallel to each other and fixed on one end of the second sliding seat 6 respectively. Both the first sliding seat 2 and the second sliding seat 6 are provided with slide rails, and the sliders 3 is provided with a first chute 31 and a second chute 32 respectively matched with the slide rails, both slide rails are partly located in the first chute 31 or the second chute 32, and the first chute 31 and the second slide groove 32 are perpendicular to each other, and the slider 3 can slide along the slide rail.

[0021] The base 1 is set for the present invention to be fixedly connected with other equipment or tooling, and the hoop part 7 provided is used to clamp the pistol drill, so that th...

Embodiment 2

[0023] This embodiment is further limited on the basis of embodiment 1: as figure 1 , the hoop portion 7 is a U-shaped structure provided with an annular through hole, and the hoop portion 7 is also provided with a tightening bolt hole 71 for adjusting the size of the annular through hole, the hoop portion 7 Be connected with the second sliding seat 6 by bolts.

[0024] The hoop portion 7 of the above structural form is simple in structure, and the annular through hole is used to match the shell of the pistol drill, and the hoop bolt hole 71 is used to install the locking bolt. After the pistol drill is put into the two hoop portions 7, The size of the annular through hole is reduced by the locking bolt, so that the present invention is suitable for the installation of pistol drills within a certain size range; at the same time, the hoop part 7 and the second sliding seat 6 are in a bolted structural form, which is convenient for replacing different The size of the hoop porti...

Embodiment 3

[0026] The present embodiment is further limited on the basis of embodiment 1: as figure 1 , in order to enable the pistol drill to automatically reset on its axis, so as to optimize the processing efficiency of the present invention in the axial direction of the hole, the second sliding seat 6 is block-shaped, and the first chute on the slider 3 31 is a T-shaped slot, and a spring 5 fixedly connected to it at one end is also arranged on the second sliding seat 6 , and the other end of the spring 5 is in contact with the slider 3 .

[0027] In order to make the present invention applicable to the drilling of deep holes, that is, to extend the length of the slide rail 61, in order to make the longer spring 5 not bend in the deformation process in this case, so as to facilitate the stability of the present invention's work, the described The second sliding seat 6 is also provided with a guide rod 4 which is threaded or bolted, the spring 5 is sleeved on the guide rod 4 , and the...

Abstract

The invention discloses a gun drill clamping mechanism suitable for hole milling. The gun drill clamping mechanism comprises at least two hoop-shaped hooping parts, a second sliding seat, a slide block and a base, wherein a first sliding seat is further arranged on the base; the hooping parts are arranged in parallel, and are fixed at one end of the second sliding seat respectively; slide rails are arranged on the first sliding seat and the second sliding seat; a first sliding chute and a second sliding chute which are matched with the slide rails are formed in the slide blocks respectively; parts of the two slide rails are positioned in the first sliding chute or the second sliding chute; the first sliding chute and the second sliding chute are vertical to each other; the slide block can slide along the slide rails. The gun drill clamping mechanism is simple in structure, and is convenient for milling holes by adopting a gun drill. Compared with the prior art in which the gun drill is held by operating personnel, the gun drill clamping mechanism has the advantages that the processing accuracy and the processing efficiency of the gun drill are increased.

Description

technical field [0001] The invention relates to a processing equipment fixture, in particular to a pistol drill clamping mechanism suitable for milling holes. Background technique [0002] At present, the pistol drills commonly used in the market include drill bits, shafts, casings, motors, etc., through one-way or two-way rotation, can be conveniently and flexibly used for drilling, boring or even milling in the production process. In the field of equipment production, the manual tube expander can even be clamped at the drill bit end of the pistol drill, and the mechanical energy of the motor can be used to replace the manual rotation of the operator. [0003] The shell of the pistol drill in the prior art is provided with a gripping part, but the pistol drill vibration caused by the resistance of the material during the working process of the pistol drill affects the accuracy of the pistol drill for material processing, while the shell of the pistol drill in the prior art ...
