[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] The thread reaming drill is a tool used to process the bottom hole of the internal thread. Its working principle is to rotate the drill bit and apply axial pressure to make the cutting edge of the drill bit cut on the existing internal thread. Since the traditional processing equipment is not convenient for fixing the drill bit, it is easy to clamp the drill bit too tightly or too loosely. Clamping too tightly may cause the drill bit to deform or damage, and clamping too loosely may cause the drill bit to move or fall during the processing, which brings great inconvenience to the processing of the drill bit. In order to avoid the situation of clamping the drill bit too tightly or too loosely and improve the processing efficiency of the drill bit, refer to Figure 1-Figure 5, provides a threaded reaming drill processing equipment, which consists of a processing table 1, a support ring 2 and a clamping mechanism 3. The support ring 2 is detachably arranged on the processing table 1, and the clamping mechanism 3 is arranged on the support ring 2 and is used to lock the reaming drill bit. The clamping mechanism 3 includes three movable splints 31 arranged on the inner side of the support ring 2 in a circumferential array. The cross-section of the movable splint 31 is set to a V-shape, which helps to clamp the drill bit more conveniently and stably. The side of the movable splint 31 in contact with the drill bit is fixedly bonded with an anti-slip pad, and movable push rods 32 are respectively fixedly arranged on one side of the three movable splints 31. Three limiting vertical grooves 33 distributed in a circumferential array are opened on the support ring 2, and the movable push rod 32 passes through one side of the limiting vertical groove 33 and is slidably connected. A limiting ring groove 34 connected to several limiting vertical grooves 33 is opened inside one side of the support ring 2. A limiting spring fixed to the support ring 2 is fixed on one side of the movable splint 31, and the initial state of the limiting spring is set to a compressed state. When the movable splint 31 moves, the limiting spring restores its elastic deformation and extends a certain distance.

[0027] A transmission assembly 35 for pushing the movable push rod 32 to move is arranged on the inner side of the limiting vertical groove 33. The clamping mechanism 3 also includes a driving assembly 36 arranged on the inner side of the limiting ring groove 34 for driving the transmission assembly 35 to operate. Through the mutual cooperation of the driving assembly 36 and the transmission assembly 35, the three movable push rods 32 are pushed to move toward the middle at the same time, and the three movable push rods 32 drive the movable clamping plate 31 to move toward the middle, so that the drill bit is stably fixed in the support ring 2, which is conducive to a better fit of the drill bit when clamped.

[0028] In order to adjust the position of the movable push rod 32 more accurately and clamp the drill bit more stably, refer to Figure 4 A transmission assembly 35 is provided, including a threaded vertical shaft 351 slidably set on the inner side of the limiting vertical groove 33 and rotating with the support ring 2 through a bearing, and a gear ring 352 rotatably set on the inner side of the limiting ring groove 34 and meshing with a transmission gear 354. A sliding seat 353 fixed to the movable push rod 32 is threadedly set on the top of the threaded vertical shaft 351. When the threaded vertical shaft 351 rotates, the sliding seat 353 drives the sliding seat 353 to slide on the inner side of the limiting vertical groove 33. A transmission gear 354 meshing with the gear ring 352 is fixed at the bottom of the threaded vertical shaft 351. The teeth of the gear ring 352 are located on the side and mesh with the transmission gear 354 for transmission.

[0029] In order to stably clamp drill bits of different diameters, which helps the drill bits to be more accurate during processing, refer to Figure 5, a driving assembly 36 is provided, including a gear ring 2 361 rotatably arranged on the inner side of the limiting ring groove 34 and fixed to the gear ring 1 352, a driven gear 362 is meshedly arranged on one side of the gear ring 2 361, a rotating shaft 363 is fixed at the axis of the driven gear 362, a driving gear 364 is fixed at one end of the rotating shaft 363, a transmission rack 365 is meshedly arranged on one side of the driving gear 364, the diameter of the driven gear 362 is larger than the diameter of the driving gear 364, and the driving gear 364 is driven to rotate when the transmission rack 365 moves, which helps to better install the positions of the driving gear 364 and the transmission rack 365, a cylinder 366 is arranged on the inner side of the limiting ring groove 34, which is fixed to the support ring 2 and is used to drive the transmission rack 365 to move, and the output shaft of the cylinder 366 is fixed to one end of the transmission rack 365.

[0030] During the actual use of the drill processing equipment, the drill bit to be processed is first placed on the inner side of the support ring 2, and then the cylinder 366 is started. The output shaft of the cylinder 366 pulls the transmission rack 365 to move, and the transmission rack 365 drives the active gear 364 meshing with it to rotate. The active gear 364 drives the rotating shaft 363 at its axis to rotate, and the rotating shaft 363 drives the driven gear 362 at one end to rotate, and the driven gear 362 drives the gear ring 2 361 on one side. The inner side of the limiting ring groove 34 rotates, and the gear ring 2 361 drives the gear ring 1 352 on one side to rotate, and the gear ring 1 352 drives the three transmission gears 354 meshing with it to rotate, and the transmission gear 354 drives the threaded vertical shaft 351 at its axis to rotate, and the threaded vertical shaft 351 drives the sliding seat 353 to slide on the inner side of the limiting vertical groove 33, and the sliding seat 353 drives the movable push rod 32 on one side to move, thereby driving the three movable clamps 31 to move toward the middle, clamping and fixing the drill bit, and then processing.
