Description

Technical Field

[0001] The present application relates to the technical field of tapping operation, and in particular to a tapping entanglement removal device for a vertical tapping machine. Background Art

[0002] Tapping is a mechanical processing operation, mainly used to process threads on workpieces, including the processing of external threads on screws and the processing of internal threads on the inner wall of nuts. When realizing batch tapping operations of internal threads, the following are usually used: Figure 1 The vertical tapping machine shown in the figure. When performing the tapping operation, the cylindrical workpiece to be tapped is clamped on the chuck on the tapping machine operating platform, and then the power shaft of the tapping machine is driven downward. The tapping rod assembled at the bottom of the power shaft enters the workpiece in a rotating state and forms an internal thread structure on the inner wall of the workpiece. Then the power shaft is moved upward to drive the tapping rod to separate from the workpiece ( Figure 2 As shown), a tapping operation is completed, and then the workpiece is disassembled and the workpiece to be tapped is loaded again to achieve continuous tapping operation.

[0003] During the tapping process, the tapping rod contacts the inner wall of the workpiece and produces a cutting effect, which allows the tapping operation to form an internal thread structure on the inner wall of the workpiece. After the inner wall of the workpiece is rotated and cut by the tapping rod, the cut chips will be entangled on the tapping rod and cannot be detached by themselves. During the next tapping, the chips entangled on the tapping rod will affect the tapping operation of the next workpiece. For example, the chips will enter the workpiece together with the tapping rod, increasing the radial width of the formed internal thread. At the same time, it will also cause processing defects such as inconsistent thread depth and random thread buckling, affecting the later assembly and use of the workpiece.

[0004] Therefore, at present, after one tapping is completed, the waste chips wrapped around the tapping rod need to be removed. There are two ways to remove the waste chips. One is to stop the machine, wait for the tapping rod to stop rotating, and then manually remove the waste chips. The shutdown process will increase the operation time and greatly affect the efficiency of batch tapping. The second is to use a high-pressure air gun ( Figure 4 As shown in the figure, the entangled waste chips are blown away by high-pressure gas. Compared with the first operation mode, this operation mode not only does not require stopping the machine, but is also more efficient than manual removal. However, its blowing effect is limited and it cannot effectively remove the entangled and tightened waste chips. Therefore, waste chips will still remain on the tapping rod, affecting the next tapping operation. Summary of the invention

[0005] In response to the above-mentioned problems, the present application aims to provide a tapping tangling removal device for a vertical tapping machine, which can mechanically remove the waste chips entangled on the tapping rod, thereby improving the efficiency of waste chip removal and the accuracy of tapping operations while solving the impact of residual waste chips on subsequent tapping operations.

[0006] In order to achieve the above-mentioned purpose, the technical solution adopted in the present application is as follows: a tapping entanglement removal device for a vertical tapping machine, the tapping machine includes a tapping rod with a tapping external thread, characterized in that: the tapping entanglement removal device is connected to the entanglement remaining on the tapping rod, and when the tapping entanglement removal device is driven to move in a direction away from the tapping rod, the entanglement gradually disengages from the tapping rod.

[0007] Preferably, the tapping entanglement removal device comprises a handle, and a removal hook body with a sickle-like structure is arranged at a circumferential interval at the top end of the handle near the side edge.

[0008] Preferably, each of the removal hook bodies comprises a fixed rod and a movable hook hinged at the top end thereof, and a torsion spring is provided at the hinge of the movable hook to drive the movable hook to an open state with the fixed rod.

[0009] Preferably, a rubber sleeve is also sleeved on the movable hook.

[0010] The beneficial effect of the present application is that the tapping tangling removal device disclosed in the present application can be mechanically connected to the tangling machine wound on the tapping rod, and the tangled waste chips can be mechanically removed under the action of this connection. Compared with the current manual shutdown removal and high-pressure air gun removal, it has the continuity of operation and the integrity of removal. On the basis of solving the influence of residual waste chips on subsequent tapping operations, the efficiency of waste chip removal is improved, thereby improving the processing accuracy of continuous tapping and ensuring the processing efficiency.

[0021] In order to enable ordinary technicians in the field to better understand the technical solution of the present application, the technical solution of the present application is further described below in conjunction with the accompanying drawings and embodiments.

[0022] See attached Figures 1 to 9 A tapping tangling removal device for a vertical tapping machine is shown, wherein the tapping machine comprises a tapping rod 1 having an external tapping thread, and the structure is as follows Figure 1 When performing the tapping operation, the cylindrical workpiece to be tapped is clamped on the chuck on the tapping machine operating platform, and then the power shaft of the tapping machine is driven downward. The tapping rod 1 installed at the bottom of the power shaft enters the workpiece in a rotating state and forms an internal thread structure on the inner wall of the workpiece. Then the power shaft is moved upward to drive the tapping rod to separate from the workpiece ( Figure 2 As shown), a tapping operation is completed, and then the workpiece is disassembled and the workpiece to be tapped is loaded again to achieve continuous tapping operation.

[0023] In order to solve the problem that during the current tapping operation, it is difficult to completely remove the waste chips entangled on the tapping rod, which affects the next tapping operation, the present application is designed with a tapping entanglement removal device, which is connected to the residual entanglement on the tapping rod 1, and when the tapping entanglement removal device is driven to move in a direction away from the tapping rod 1, the entanglement and the tapping rod 1 are gradually separated, that is, the tapping entanglement removal device is connected to the waste chips entangled on the tapping rod, and mechanical removal is achieved after the connection. Compared with the current manual shutdown removal and high-pressure air gun removal, it has the continuity of operation and the integrity of removal. On the basis of solving the influence of the residual waste chips on the subsequent tapping operation, the efficiency of waste chip removal is improved, thereby improving the processing accuracy of continuous tapping and ensuring the processing efficiency.

[0024] Specifically, Figure 5 As shown, the tapping entanglement removal device includes a handle 2, and a sickle-like removal hook 3 is arranged at a circumferential interval near the side of the top of the handle 2. When operating, preferably, two removal devices (such as Figure 6As shown in the figure, the operator holds the handle 2 and extends the tip of the removal hook 3 into the winding waste, and then Figure 6 The direction of the arrow a drives the removal hook body 3 to move away from the outer wall of the tapping rod 1, and at the same time, the removal hook body 3 drives the entangled waste chips to separate from the outer wall of the tapping rod 1, so that the entangled waste chips are in a loose state ( Figure 7 As shown), and then Figure 8 As shown, the handle 2 is moved downward so that the loose waste chips can be smoothly separated from the tapping rod 1, thereby achieving a quick and complete removal operation of the entangled waste chips, and then the assembly and continuous tapping operation of the next workpiece can be carried out.

[0025] The multiple removal hook bodies 3 (preferably three in the present application) arranged along the circumferential direction can be connected to the waste chips from different positions of the wound waste chips, thereby improving the tightness of the connection between the removal hook body 3 and the waste chips and avoiding the problem that the removal hook body 3 is easily separated from the waste chips after a single removal hook body 3 is connected to the waste chips and then in the process of driving the hook body to pull the waste chips.

[0026] Since the tapping rod 1 is in a rotating state when performing the winding waste chip removal operation in the above-mentioned application, in order to avoid the problem of rotational collision caused by the manual driving of the removal hook body 3 in the process of connecting with the waste chips, the tapping rod 1 is easily contacted with the outer wall of the tapping rod 1, such as Figure 5 As shown, each of the removal hook bodies 3 includes a fixed rod 31 and a movable hook 32 hinged at its top, and a torsion spring (not shown in the figure) is provided at the hinge of the movable hook 32 to drive it to an open state with the fixed rod 31. The function of this structure is that when the movable hook 32 contacts the outer wall of the tapping rod 1, the tapping rod 1 drives the movable hook 32 to overcome the force of the torsion spring and move toward the fixed rod 31. Fig. 9 The movable hook 32 rotates in the direction of the arrow b in the middle, thereby avoiding the relative wear of the movable hook 32 and the tapping rod 1 caused by hard contact between the two, and the problem of large contact impact feedback to the operator, thereby improving the safety of operation. When the movable hook 32 and the tapping rod 1 are separated, the force of the torsion spring drives the movable hook 32 and the fixed rod 31 to return to the position as shown in the figure. Figure 5 Opening state shown.

[0027] When the entangled waste chips are too tightly wound around the tapping rod 1, the machine can be stopped to remove the entangled waste chips. In order to further speed up the removal efficiency of the entangled waste chips, a high-pressure air gun can be used to blow them away first. The waste chips that cannot be blown away can be mechanically removed by the device of the present application, and those that are more difficult to remove can be removed by stopping the machine. The present application uses a removal device to mechanically remove, and most of the entangled waste chips can be completely removed.

[0028] In order to further reduce the problem that the movable hook 32 may damage the outer wall thread of the tapping rod 1 after contacting the tapping rod 1, thereby affecting the tapping accuracy, Fig. 9As shown, a rubber sleeve 4 is also sleeved on the movable hook 32. When the movable hook 32 contacts the tapping rod 1, the rubber sleeve 4 contacts the external thread on the outer wall of the tapping rod 1, which can effectively reduce the damage to the external thread on the surface of the tapping rod 1 and increase the service life of the tapping rod 1.

[0029] The principle of the present application is: when operating, two removal devices are used at the same time, the operator holds the handle 2, extends the tip of the removal hook 3 into the entangled waste, and then Figure 6 The direction of the arrow a drives the removal hook body 3 to move away from the outer wall of the tapping rod 1, and at the same time, the removal hook body 3 drives the entangled waste chips to separate from the outer wall of the tapping rod 1, so that the entangled waste chips are in a loose state, and then Figure 8 As shown, the handle 2 is moved downward so that the loose waste chips can be smoothly separated from the tapping rod 1, thereby achieving a quick and complete removal operation of the entangled waste chips, and then the assembly and continuous tapping operation of the next workpiece can be carried out.

[0030] The above shows and describes the basic principles, main features and advantages of the present application. Without departing from the spirit and scope of the present application, the present application may have various changes and improvements, which fall within the scope of the present application to be protected.
