Embodiment 1

[0026] Such as figure 1 with figure 2 , a pistol drill clamping mechanism that is convenient for changing the position of the drill provided by the present invention includes at least two hoop-like hoop parts 7, a first sliding seat 2, a second sliding seat 6, a slider 3 and a base 1. The base 1 is also provided with a rotating hole, and a rotating seat 13 is arranged in the rotating hole to form a clearance fit with it. The rotating seat 13 can rotate around the axis of the rotating hole, and the rotating seat 13 is also fixed with a hinged rod 11. The hoop parts 7 are parallel to each other and are respectively fixed on one end of the second sliding seat 6, the first sliding seat 2 and the second sliding seat 6 are provided with slide rails, and the slide block 3 is provided with slide rails which are respectively connected to the sliding seat 6. The rails match the first chute 31 and the second chute 32, the two slide rails are partially located in the first chute 31 or t...

Embodiment 2

[0029] This embodiment is further limited on the basis of embodiment 1: as figure 1 with figure 2 , 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.

[0030]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...

Embodiment 3

[0032] The present embodiment is further limited on the basis of embodiment 1: as figure 1 with figure 2 , 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 .

[0033] 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...

Abstract

The invention discloses a pistol drill clamping mechanism with a position of a drill to be changed conveniently. The pistol drill clamping mechanism comprises at least two hoop-shaped hoop parts, a first slippage seat, a second slippage seat, a sliding block and a base, wherein a rotating hole is formed in the base; a rotating seat in clearance fit with the rotating hole is arranged in the rotating hole; a hinge rod is also fixed on the rotating seat; sliding rails are respectively arranged on the first slippage seat and the second slippage seat; a first sliding chute and a second sliding chute matched with the sliding rails are respectively arranged on the sliding block; a hinge nail is also arranged on the hinge rod or the first slippage seat; the hinge rod is connected with the first slippage seat through the hinge nail through a hinge way; the axis of the hinge nail is vertical to the axis of the rotating hole. According to the pistol drill clamping mechanism, the structure is simple; compared with a pistol drill manually held by operating personnel in the prior art, an isometrical arc or a taper arc can be milled conveniently, the processing accuracy and the processing efficiency of the pistol drill are improved, the application scope of the pistol drill fixed on the pistol drill clamping mechanism is enlarged, and the structure of equipment or a tool for fixing the pistol drill clamping mechanism is simplified.

Description

technical field [0001] The invention relates to a processing equipment fixture, in particular to a pistol drill clamping mechanism which is convenient for changing the position of a drill bit. 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 ...
