The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.
As shown in fig. 1 and 2, a portable screw thread making and repairing tool comprises a clamping piece 1, a fixing piece 2 and a threading die 3, wherein the clamping piece 1 is connected with a rotating tool 4, and the rotating tool 4 rotates to drive the clamping piece 1 to rotate; the tail end of the fixing piece 2 is connected with the clamping piece 1, and the fixing piece 2 is provided with an accommodating cavity; the screw die 3 is fastened in the accommodating cavity of the fixing part 2, the screw rod 5 penetrates into the screw die 3, and thread making or thread repairing is realized through the rotating screw die 3.
When the portable thread manufacturing and repairing tool is used, the damaged thread is repaired or a new thread is manufactured through the threading die 3; the portable thread manufacturing and repairing tool can be connected with tools such as an electric hand drill and a pneumatic drill, replaces manpower to repair or manufacture threads, reduces labor intensity and improves working efficiency.
The following provides a preferred embodiment of the above embodiment with respect to the fixture:
the fixing piece 2 is cylindrical, the screw die 3 is a tubular screw die, a screw 6 is arranged on the arc-shaped side surface of the fixing piece 2, and the screw 6 can be screwed in and out of the fixing piece 2; after the screw 6 is screwed in, the die 3 is pressed, so that the die 3 is fixed in the fixing member 2 and rotates along with the fixing member 2; when the screw 6 is screwed out, the screw is separated from the die 3, so that the die 3 is moved out of the fixing part 2, and the dies 3 with different types are replaced to match with the screw rods 5 with different thicknesses, thereby increasing the application of the portable thread manufacturing and repairing tool. That is, the dies 3 with small inner diameters may be used for the thin screws 5, and the dies 3 with large inner diameters may be used for the thick screws 5.
The following gives a preferred embodiment of the above embodiment with respect to the clamping member:
the clamping piece 1 is a round rod, and the clamping piece 1 and the fixing piece 2 are welded or integrally cast. When the clamping piece is actually used in our factory, the clamping piece 1 and the fixing piece 2 are made of Q235 steel and are integrally formed through lathe machining. Of course, a welding mode can be selected, but the welding mode is not attractive due to integral forming.
As the utility model discloses an optimization scheme: the outer surface of the clamping piece 1 is rough surface for increasing the friction force with the rotating tool 4.
The preferred scheme is as follows: as shown in fig. 4, the outer side of the clamping member 1 is provided with a plurality of convex points or concave points, so as to form a rough surface. Of course, the outer edge surface of the clamping member 1 may be a threaded surface, and the number of rough surfaces is many, which is not listed here.
As the utility model discloses an optimization scheme: the arc-shaped side face of the die 3 is provided with a row of arranged grooves 7, the screws 6 are positioned in different grooves 7 to realize the extension and contraction of the die 3 in the fixing part 2, and the extended die 3 can be used for manufacturing or repairing longer threads on the screw rod 5. Namely, when the screw 6 is positioned in the first groove 7, the die 3 is just positioned in the fixing piece 2, and the length which can be penetrated by the screw rod 5 is about the depth of the accommodating cavity of the fixing piece 2; when the screw 6 is positioned in the second groove 7, the die 3 extends out of the fixing member 2 by a preset length L1, and the length of the screw rod 5 which can penetrate is about the depth of the accommodating cavity of the fixing member 2 plus the length L1; when the screw 6 is in the third groove 7, the die 3 extends out of the fixing member 2 by a predetermined length L2, and the length that the screw rod 5 can penetrate is about the depth of the accommodating cavity of the fixing member 2 plus the length L2.
As the utility model discloses an optimization scheme: as shown in fig. 3, at least one elongated hole 8 is provided at the rear end of the fixing member 2 for observing the screw 5 in the die 3, and when the screw 5 is observed from the elongated hole 8, the rotation of the tool 4 is stopped. In actual operation, if the long hole 8 is not provided, the position of the screw 5 in the fixing part 2 is not known when the screw 5 is repaired, and if the screw 3 continues to rotate in place after the screw 5 abuts against the top surface of the accommodating cavity of the fixing part 2, the screw 3 can damage the thread which is already made on the screw 5. Therefore, the position of the screw 5 can be roughly observed through the long-line hole 8, and the thread is prevented from being damaged. Of course, the long row of holes 8 can be made in two or three, and a plurality of long rows of holes 8 surround the bottom of the side surface of the fixing member 2, thereby realizing multiple aspects of observation.
It should be noted that the rotary tool 4 is an electric hand drill or a pneumatic drill. Of course, other rotating tools may be used and are not limited to the rotating tools set forth above.
As shown in fig. 5 and 6, when the tool is used, firstly, the diameter of a screw rod 5 is measured through a measuring ruler (a vernier caliper can be selected), then a matched die 3 is selected (certainly, if the depth of a screwed-out thread is required, dies with different internal thread depths are matched), the selected die 3 is installed in a fixing piece 2, the die 3 is fixed through a screwed screw 6 (if the screw rod is not long, the die does not need to be extended, and if the screw rod is long, the die needs to extend out of a fixing piece accommodating cavity by a preset length), then a clamping piece 1 is fixed at a drill chuck of an electric hand drill, the die 3 is moved to the end of the screw rod, and the drill chuck rotates after a switch of the electric hand drill is pressed (at this time, the drill chuck rotates positively), so that the die 3 is driven to rotate.
If the screw rod 5 is bald, the screw thread is gradually screwed out from the rotated screw die 3 on the screw rod 5, the switch of the electric hand drill is closed after the preset screw thread is screwed out, the electric hand drill is toggled to rotate forward and backward, the switch of the electric hand drill is pressed, and then the drill chuck rotates (is set to rotate backward at the moment), so that the screw die 3 is driven to rotate, and the screw die 3 is gradually screwed out along the screw thread.
If prosthetic screw rod 5, screw die 3 after the rotation is along original screw thread precession gradually, when reacing needs prosthetic screw thread department, screw die 3 can back-out new screw thread on the screw rod of floating, closes electric hand drill switch after screw thread restoration is accomplished, stirs electric hand drill and just reverses the switch back and presses electric hand drill switch back drill chuck and rotate (establish to the reversal this moment) to drive screw die 3 and rotate, screw die 3 back-out gradually along the screw thread.
To sum up, the utility model is simple in operation, convenient to use have eliminated the potential safety hazard of the major possession handling operation of machine maintenance factory, have improved the work efficiency that equipment lifted by crane, have established good basis for accomplishing the equipment fixing of my intelligent comprehensive working face of adopting in mine smoothly.
Taking a wiring terminal bolt for overhauling the explosion-proof switch as an example: the cost of replacing a brand-new wiring terminal is 100 yuan each, the repairing cost of the wiring terminal is 3 yuan each by using a special tool, and the input-output ratio is calculated according to 40 switches repaired every month: 40X2X3:40X2X100=1: 33.3.
