[0002] A tap is a tool for processing internal threads. According to its shape, it can be divided into spiral groove taps, blade angle taps, straight groove taps and pipe thread taps. According to the use environment, it can be divided into hand taps and machine taps. According to the specifications, it can be divided into metric, American, and imperial taps. Taps are the most mainstream processing tools used by manufacturing operators when tapping.

[0003] After the tap is produced and formed, a grinder is needed to be used. The tail end of the tap is installed on the tap grinder, and then the head end of the tap is inserted into the grinding sand. The grinder drives the tap to rotate, and then the head of the tap is rotated and ground inside the grinding sand.

[0004] At present, when fixing the taps, the grinding machines usually use magnetic suction to fix the taps, which is relatively simple. In addition, taps of different lengths are usually ground at the same time, so that the single magnetic suction method cannot be adjusted for a variety of taps. When the rotating disk drives the taps to rotate and grind inside the grinding barrel, the taps are easily shaken and fall, affecting the normal processing of the taps. Summary of the invention

[0007] Furthermore, both ends of the fixing member are rotatably connected with a transmission rod, a first slide groove is provided on the front end surface of the transmission rod, and a second slide groove is provided on the left end surface of the transmission rod.

[0008] Furthermore, a fixing sleeve is provided on the lower side of the transmission rod, and a fixing rod is fixedly installed between the fixing sleeve and the support plate.

[0009] Furthermore, an insertion rod is slidably connected to the end of the fixing sleeve, and the insertion rod passes through the second slide groove and is slidably connected to the second slide groove.

[0010] Furthermore, a sliding rod is fixedly mounted on the outer surface of the insertion rod, and the sliding rod is slidably connected to a sliding groove.

[0011] Furthermore, the lower side of the fixing member is spirally connected to a tap body, the outer surface of the tap body is provided with a slot, and the insertion rod is inserted into the slot.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The utility model provides an insertion rod, and uses manual pressing of the extrusion plate to drive the threaded rod to rotate, and the insertion rod is pulled out from the slot provided on the tap body, thereby releasing the fixed state of the tap body and completing the replacement of the tap body.

[0024] When the tap body 19 needs to be ground, the tap body 19 is placed in a fixing mechanism in the grinder, and then the device is started. The grinder is a prior art and is not described in detail in this application.

[0025] Both ends of the fixing member 11 are rotatably connected with a transmission rod 12 . A first slide groove 13 is provided on the front end surface of the transmission rod 12 , and a second slide groove 14 is provided on the left end surface of the transmission rod 12 .

[0026] A fixing sleeve 16 is provided at the lower side of the transmission rod 12 , and a fixing rod 15 is fixedly installed between the fixing sleeve 16 and the support plate 1 .

[0027] When the tap body 19 needs to be fixed, the extrusion plate is manually pressed to lower the rack 7, and the gear 10 on the threaded rod 9 is meshed with the rack 7, thereby driving the threaded rod 9 to rotate.

[0028] The end of the fixing sleeve 16 is slidably connected with an insert rod 17 , which passes through the second slide groove 14 and is slidably connected with the second slide groove 14 .

[0029] The threaded rod 9 is a bidirectional threaded rod 9, so the transmission rod 12 connected to the threaded rod 9 in a spiral transmission manner will move in opposite directions.

[0030] A sliding rod 18 is fixedly mounted on the outer surface of the insert rod 17 , and the sliding rod 18 is slidably connected to the sliding groove 13 .

[0031] The transmission rod 12 will deflect around the fixing member 11 , and the insertion rod 17 is slidably connected to the sliding groove 14 on the transmission rod 12 through the sliding rod 18 , so when the transmission rod 12 rotates clockwise, the insertion rod 17 will retract into the inside of the fixing sleeve 16 .

[0033] Then, the tap body 19 to be ground is screwed onto the fixing member 11, and the pressing plate 3 is released. The rack 7 rises under the action of the spring 6, and the transmission structure is reversed, so that the insertion rod 17 can be inserted into the slot 20 on the tap body 19, thereby fixing the tap body 19.

[0034] Working principle: When the tap body 19 needs to be ground, the tap body 19 is placed in the fixing mechanism of the grinder, and then the device is started. The grinder is a prior art and is not described in detail in this application. When the tap body 19 needs to be fixed, the rack 7 is lowered by manually pressing the extrusion plate, and the gear 10 on the threaded rod 9 is meshed with the rack 7, thereby driving the threaded rod 9 to rotate. The threaded rod 9 is a bidirectional threaded rod 9, so the transmission rod 12 connected to the threaded rod 9 in a spiral transmission will move in opposite directions. , the transmission rod 12 will deflect around the fixing member 11, and the insertion rod 17 is slidably connected with the slide groove 14 on the transmission rod 12 through the slide rod 18. Therefore, when the transmission rod 12 rotates clockwise, the insertion rod 17 will retract into the inside of the fixing sleeve 16, and then the tap body 19 to be ground will be spirally fixed on the fixing member 11. At the same time, the pressing plate 3 is released, and the rack 7 will rise under the action of the spring 6. The above transmission structure is reversed, so that the insertion rod 17 can be inserted into the slot 20 on the tap body 19, thereby completing the fixation of the tap body 19.
