Description

Technical Field

[0001] The present application relates to the technical field of tapping machines, and in particular to a fully automatic tapping machine for machining filter housing mounting holes. Background Art

[0002] As an important part of the engine, the filter plays a role in filtering impurities or gases in the engine's lubrication, combustion and intake systems, thereby effectively extending the service life of the components. Due to the filtering function of the filter, it needs to be replaced after a long period of use. As a result, the filter is often installed in a threaded connection to facilitate its disassembly and assembly.

[0003] However, when the existing tapping machine is performing a tapping operation, due to the characteristics of the thread engagement, the tap needs to be driven to rotate in the reverse direction to be withdrawn after the tapping is completed. As a result, the operator needs to constantly control the forward and reverse rotation of the tapping machine during the tapping operation. The operation steps are relatively cumbersome and the efficiency of manual control of the forward and reverse rotation of the tap is relatively low. At the same time, it is difficult to grasp the timing of manual control of the forward and reverse rotation of the tapping machine, which makes the tapping machine often perform useless work, which invisibly increases the energy consumption of the tapping machine and has poor stability and reliability.

[0004] Therefore, there is an urgent need for a transmission structure for a tapping machine to solve the defects of the above-mentioned existing tapping machines during actual use. Summary of the Invention

[0005] The present application proposes a fully automatic tapping machine for processing filter housing mounting holes, which has the function of automatically controlling the forward and reverse rotation of the tap according to the position state of the tap, without the need for human intervention in regulation, and the control of the forward and reverse rotation timing of the tap is relatively accurate, effectively reducing the useless work of the tapping machine, and having the advantages of high stability and reliability. It is used to solve the problem that due to the characteristics of thread engagement, the tap needs to be driven in the reverse direction to be rotated to withdraw it after tapping is completed, which causes the operator to constantly control the forward and reverse rotation of the tapping machine during the tapping operation. The operation steps are relatively cumbersome and the efficiency of manual control of the forward and reverse rotation of the tap is relatively low. At the same time, it is difficult to grasp the timing of manual control of the forward and reverse rotation of the tapping machine, which makes the tapping machine often produce useless work.

[0006] To achieve the above-mentioned purpose, the present application adopts the following technical solution: a fully automatic tapping machine for processing the mounting hole of a filter housing, comprising a transmission shaft fixedly connected to a power output mechanism at the top end, and a tap for tapping the filter housing is clamped at the bottom end of the transmission shaft, an inner ring groove I is opened in the middle part of the transmission shaft, and an inner ring sleeve is movably sleeved in the inner ring groove I, and at the same time, a shaft shoulder is provided at the top of the outer surface of the transmission shaft, a first elastic member is movably sleeved on the top of the outer surface of the transmission shaft and located on the shaft shoulder, and the transmission connection between the transmission shaft and the inner ring sleeve is achieved through the first elastic member, and then under the elastic force of the first elastic member, the inner ring sleeve always maintains a tendency to move upward, and in the process of the operator lowering the inner ring sleeve for tapping, the forward rotation of the power output mechanism is controlled by the mutual movement between the transmission shaft and the inner ring sleeve;

[0007] An outer ring sleeve is movably connected to the outer surface of the inner ring sleeve, and an inner ring groove II is provided at the bottom of the inner wall of the outer ring sleeve. At the same time, an annular protrusion is fixedly installed at the bottom of the outer surface of the inner ring sleeve. A second elastic member is movably connected to the outer surface of the inner ring sleeve and located on the annular protrusion, and the inner ring sleeve and the outer ring sleeve are connected by transmission through the second elastic member. Then, under the elastic force of the second elastic member, the outer ring sleeve always maintains a tendency to move upward, and in the process of the operator moving the outer ring sleeve upward to withdraw the tap, the reversal of the power output mechanism is controlled by the mutual movement between the inner ring sleeve and the outer ring sleeve.

[0008] Furthermore, a first carbon ring is fixedly sleeved on the bottom of the inner ring groove I, and a first conductive ring is fixedly sleeved on the bottom of the inner wall of the inner ring sleeve, and a current loop for controlling the forward rotation of the transmission shaft is formed between the first carbon ring and the first conductive ring, and is energized and triggered when the first carbon ring contacts the first conductive ring. When the tap contacts the hole on the filter housing, the operator continuously drives the transmission shaft and the structure thereon downward through the outer ring sleeve. Due to the obstruction of the filter housing, the transmission shaft and the inner ring sleeve move relative to each other and compress the first elastic member until the first carbon ring contacts the first conductive ring and triggers the forward rotation of the power output mechanism, thereby driving the tap at the bottom end of the transmission shaft to rotate forward to perform tapping operation on the filter housing.

[0009] After the tapping of the hole on the filter housing is completed, since there is no shearing action, the tap will quickly drive the shaft and the tap on it will quickly move downward, and under the elastic force of the first elastic member in the compressed state, the first carbon ring and the first conductive ring are separated from each other and the current circuit of the forward rotation of the drive shaft is cut off.

[0010] Furthermore, a second conductive ring is fixedly installed on the top of the outer ring sleeve, and a second carbon ring is fixedly sleeved on the top of the outer surface of the inner ring sleeve, and a current circuit for controlling the reversal of the transmission shaft is formed between the second carbon ring and the second conductive ring, and is energized and triggered when the second carbon ring contacts the second conductive ring. After the tapping of the hole on the filter housing is completed, the operator drives the transmission shaft and the structure thereon to move upward through the outer ring sleeve. Due to the engagement of the tap with the threaded hole on the filter housing, the inner ring sleeve and the outer ring sleeve move relative to each other, so that the second conductive ring and the second carbon ring come into contact and trigger the reversal of the power output mechanism, thereby driving the tap at the bottom end of the transmission shaft to reverse and withdraw it from the threaded hole on the filter housing.

[0011] Furthermore, initially, when the outer ring sleeve is not affected by external force, the outer ring sleeve compresses the second elastic member downward under the action of gravity, so that there is no contact between the second carbon ring and the second conductive ring, thereby ensuring that under normal circumstances, the power output mechanism will not cause the transmission shaft and the tap thereon to reverse.

[0012] Furthermore, the maximum compression displacement of the first elastic member is greater than the maximum distance between the first carbon ring and the first conductive ring, thereby ensuring that the first carbon ring and the first conductive ring can come into contact during the process of mutual displacement between the transmission shaft and the inner ring sleeve and compression of the first elastic member, so that the tapping machine is not prone to poor contact during normal operation.

[0013] Furthermore, a clamping sleeve for clamping a tap is fixedly installed on the bottom end of the transmission shaft, and through the setting of the clamping sleeve, the tapping machine can be adapted to taps of different specifications and models, thereby effectively improving the applicability of the tapping machine.

[0014] Furthermore, a handle assembly is fixedly mounted on one side of the outer surface of the outer ring sleeve for controlling the up and down movement of the outer ring sleeve during tapping operations.

[0015] The beneficial effects of the present invention are as follows:

[0016] The present application provides a fully automatic tapping machine for processing filter housing mounting holes. With respect to the arrangement of the inner ring sleeve and the linkage structure thereon, the operator can regulate the forward or reverse rotation of the tap by forcing the inner ring sleeve to move upward or downward during the tapping operation, without the need for manual participation in regulating the forward and reverse rotation of the tap. At the same time, the forward rotation state of the tap can be cut off according to the shear force exerted on the tap, thereby making it possible for the tapping machine to have a more accurate grasp of the forward and reverse rotation timing during the tapping operation, effectively reducing the useless work of the tapping machine and achieving higher stability and reliability.

DETAILED DESCRIPTION

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] like Figure 1 、 Figure 2 As shown, a fully automatic tapping machine for processing filter housing mounting holes includes a transmission shaft 1 whose top end is fixedly connected to the power output mechanism, and a tap for tapping the filter housing is clamped at the bottom end of the transmission shaft 1. Figure 3-Figure 5As shown, the middle part of the transmission shaft 1 is provided with an inner ring groove I 2, and an inner ring sleeve 4 is movably sleeved in the inner ring groove I 2. Meanwhile, the top of the outer surface of the transmission shaft 1 is provided with a shaft shoulder 3, and the top of the outer surface of the transmission shaft 1 and the shaft shoulder 3 are movably sleeved with a first elastic member 5. The transmission shaft 1 and the inner ring sleeve 4 are connected through the first elastic member 5. Under the elastic force of the first elastic member 5, the inner ring sleeve 4 always tends to move upward. During the process of moving the inner ring sleeve 4 downward for tapping operation by the operator, the transmission shaft 1 and the inner ring sleeve 4 are moved to control the forward rotation of the power output mechanism.

[0028] The outer surface of the inner ring sleeve 4 is movably sleeved with an outer ring sleeve 7, and the bottom of the inner wall of the outer ring sleeve 7 is provided with an inner ring groove II 9. Meanwhile, the bottom of the outer surface of the inner ring sleeve 4 is fixedly installed with an annular protrusion 6, and the outer surface of the inner ring sleeve 4 and the annular protrusion 6 are movably sleeved with a second elastic member 8. The inner ring sleeve 4 and the outer ring sleeve 7 are connected through the second elastic member 8. Under the elastic force of the second elastic member 8, the outer ring sleeve 7 always tends to move upward. During the process of moving the outer ring sleeve 7 upward to exit the tap by the operator, the inner ring sleeve 4 and the outer ring sleeve 7 are moved to control the reverse rotation of the power output mechanism.

[0029] As shown in Figure 3 , Figure 4 and Figure 6 , in the technical solution, the bottom of the inner ring groove I 2 is fixedly sleeved with a first carbon ring 10, and the bottom of the inner wall of the inner ring sleeve 4 is fixedly sleeved with a first conductive ring 11. The first carbon ring 10 and the first conductive ring 11 form a current loop for controlling the forward rotation of the transmission shaft 1. When the first carbon ring 10 and the first conductive ring 11 are in contact, the power output mechanism is triggered by power. When the tap and the hole position on the filter shell are in contact, the operator continuously drives the transmission shaft 1 and the structure thereon to move downward through the outer ring sleeve 7. Due to the blockage of the filter shell, the transmission shaft 1 and the inner ring sleeve 4 are moved and the first elastic member 5 is compressed. Until the first carbon ring 10 and the first conductive ring 11 are in contact and the power output mechanism is triggered to rotate forward, the tap located at the bottom end of the transmission shaft 1 is rotated forward to tap the filter shell;

[0030] After tapping the hole position on the filter shell, there is no shearing action, so that the tap and the tap on the transmission shaft 1 will quickly move downward. Under the elastic force of the first elastic member 5 in the compressed state, the first carbon ring 10 and the first conductive ring 11 are separated from each other and the current loop for the forward rotation of the transmission shaft 1 is cut off.

[0031] As shown in Figure 4 , Figure 5 and Figure 7As shown in the technical solution, the top of the outer ring 7 is fixedly installed with a second conductive ring 13, and the top of the outer surface of the inner ring 4 is fixedly sleeved with a second carbon ring 12, and a current loop for reversing the transmission shaft 1 is formed between the second carbon ring 12 and the second conductive ring 13, and the second carbon ring 12 and the second conductive ring 13 are electrified and triggered when they are in contact. After tapping the hole on the filter housing is completed, the operator drives the transmission shaft 1 and the structure thereon upward, and because the tap is engaged with the threaded hole on the filter housing, the inner ring 4 and the outer ring 7 are moved relative to each other, the second conductive ring 13 and the second carbon ring 12 are in contact and trigger the power output mechanism to reverse, and then drive the tap at the bottom end of the transmission shaft 1 to reverse to exit from the threaded hole on the filter housing.

[0032] As shown in the technical solution, Figure 1 , Figure 7 In the initial state, the outer ring 7 is not affected by external force, and under the action of gravity, the outer ring 7 compresses the second elastic member 8 downward, so that the second carbon ring 12 and the second conductive ring 13 are not in contact, and thus the power output mechanism will not drive the transmission shaft 1 and the tap thereon to reverse in normal circumstances.

[0033] In the technical solution, the maximum compression displacement of the first elastic member 5 is greater than the maximum distance between the first carbon ring 10 and the first conductive ring 11, so that the first carbon ring 10 and the first conductive ring 11 can be in contact during the mutual displacement and compression of the transmission shaft 1 and the inner ring 4, so that the tapping machine is not prone to poor contact during normal operation.

[0034] In the technical solution, the bottom end of the transmission shaft 1 is fixedly installed with a clamping sleeve for clamping the tap, so that the tapping machine can be adapted to different specifications and models of taps, thereby effectively improving the application range of the tapping machine.

[0035] As shown in the technical solution, Figure 5 In the technical solution, the outer surface of the outer ring 7 is fixedly installed with a handle assembly for controlling the up and down movement of the outer ring 7 during tapping operation.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
