Description

Screw Tap Socket Fixture

The utility model relates to an operating tool for tapping a thread on a workpiece hole, in particular to a screw tapping sleeve fixture which can be directly assembled with a pneumatic tool to tap and ream the hole on the workpiece.

Generally, the traditional way of thread tapping, in addition to using a larger special machine for thread tapping and reaming, mostly uses a relatively simple manual screw tapping fixture. Referring to Fig. 4, the traditional manpower screw tapping fixture 6 shown, it relies on a group of rotatable handles 61; The hole 71 of the workpiece 7 is tapped and threaded. However, general thread tapping and reaming machines are mostly used for processing small workpieces that can be picked up by manpower, and for larger or immovable workpieces, it is necessary to spend more money to purchase large-scale thread tapping and reaming. Using a special machine is not only uneconomical and inflexible, but also cannot overcome the processing problems of immovable workpieces (such as on the production line or formed mechanical equipment). Therefore, the most economical way is to use the manual screw tapping fixture 6 as shown in FIG. 4 . It is believed that the vast majority of people with a mechanical background know that it takes considerable effort and is very inefficient to use this kind of manpower screw tapping jig to tap the thread. When the hole 71 of the tapped thread has a small diameter, it can barely Construction, if hole 71 aperture increases, then must apply larger strength, even produce the situation that can't construct with manpower at all, this situation except waste man-hour and manpower, also makes the processing efficiency of workpiece 7 reduce, so that cause Processing costs increase. In the current situation of sharply rising wages, how to take economical and effective measures has become the primary task of people in the industry.

In view of the practical difficulties of the traditional manual screw tapping fixture, the purpose of this utility model is to provide a screw tap for tapping screw threads, one end of which can clamp the screw tap and the other end can be combined with a pneumatic tool. Socket clamps, and make it possible to increase work efficiency and reduce costs.

Solution of the present utility model is as follows. The sleeve fixture is composed of a set-up part, a locking part, a clamping claw, a tension spring, and an adjustment clamping part. A lock-up part with an appropriate range of threads on the outer edge is formed at one end of the set-up part of the sleeve fixture. A storage area is provided on the central upper part of the locking part, a group of symmetrical clamping claws are installed in the storage area, and a cut groove is extended downward from the center of the storage area. A -shaped tension spring is installed in the groove, and the two arms of the -shaped tension spring respectively penetrate into the perforations provided at the bottom of the set of clamping claws, and on the relative top outer edge of the set of clamping claws, Each is provided with an arc-shaped slope, and on the inner surface of each clamping claw, each is provided with a corresponding V-shaped clamping notch, and a hollow tubular adjustment clamping part is screwed on the locking part. The lower section of the inner hole is provided with threads and the upper section is provided with an inclined cone surface, and a square sleeve hole is provided on the end surface of the sleeve clamp at the other end of the sleeve clamp, and a steel ball positioning groove is provided on the inner wall of the square sleeve hole.

When the utility model with the above-mentioned structure is in use, the square sleeve hole opened inwardly by the end face of the sleeve part can be matched with the sleeve end of the front end of the pneumatic tool to form a whole, and the power provided by the pneumatic tool is used to drive the utility model. The utility model carries out the operation of tapping. By rotating and adjusting the clamping member, the arc-shaped inclined surface on the top outer edge of the set of clamping claws can be pushed by the inclined cone surface in the adjusting clamping member, so that the distance between the set of clamping claws can be changed. Clamps taps of different sizes.

It can be seen from the above that the utility model provides a screw tapping sleeve fixture that is labor-saving, easy to use and high in efficiency, which can save manpower and working hours, improve economic benefits, reduce product costs, and can be widely popularized and applied in the industry.

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

See Figures 1 to 3. The utility model forms a locking part 2 with an appropriate range of threads 21 on one end of the sleeve fixture 1 at one end of the sleeve fixture 1, and an accommodating clamping claw 3 is provided at the central upper section of the locking part 2. Zone 22, and extends downward from the center of the accommodating zone 22 to provide a slot 221, in which a -shaped tension spring 34 is installed in the slot 221, and the two arms 341 of the -shaped tension spring 34 Penetrate respectively in the perforation 33 that this group of clamping jaws 3 bottoms offer, and make these two clamping jaws 3 keep the state of relatively open because of the tension force of tension spring 34, on the opposite top of this group of clamping jaws 3 Each outer edge is provided with an arc-shaped inclined surface 31 , and each inner surface of each clamping claw 3 is provided with a corresponding V-shaped clamping notch 32 . In addition, a hollow tubular adjustment clamping member 4 is screwed onto the locking portion 2. The lower section of the inner hole of the adjustment clamping member 4 has a thread 41 and the upper section has a tapered surface 42. By rotating the adjustment clamping member 4 , the arc-shaped inclined surface 31 on the top outer edge of the group of clamping claws 3 can be pushed by the inclined tapered surface 42 in the adjustment clamping member 4, so that the distance between the group of clamping claws 3 can be changed, so that the clamping claws can be clamped Screw taps 35 of different sizes are fixed, and an inward square sleeve hole 111 is provided on the end face of the sleeve fixture 1 other end of the sleeve fixture 11, and a steel ball positioning groove 112 is also provided on the inner wall of the square sleeve hole 111. , thus can rely on this square sleeve hole 111 and the group sleeve end 51 of pneumatic tool 5 front ends to be combined into one, just can carry out the processing of tapping screw thread to workpiece 7.
