Description

Taper safety special torque tool and metal plate for preventing impact when torque is generated

The invention relates to a special torque tool for tap safety and a metal plate for preventing impact when torque is generated, in particular, mainly in the process of connecting with a drill, forming a hole drill or forming a screw connection of a turnbuckle. Install the torque tool on the underside of the main shaft. If there is an overload of torque applied to the drill or tap, the power transmitted from the main shaft will not be transmitted to the drill or tap, but will be turned inside the torque tool to prevent it. The drill or tap is broken and the drill or tap is safely protected.

In general, a bench drill is capable of performing drilling, tapping, reaming, boring, depending on the type of tool mounted on the finished product fixedly mounted to the console. A device that operates such as a spot-facing, a counter sinking, or the like. During operation, when drilling with a drill or tap, when a large torque is applied to the tool, the drill or tap will break, the tool cannot be used, and only a new one can be replaced, which will result in a very large economy. loss. At this point, if the drill chuck stops rotating or the rotation of the drill chuck is transmitted to the drill or tap, it can be prevented from breaking, but such a device has not been developed.

The bench drill is performed, for example, after the drill or tap is connected to the drill chuck, the through hole 2 or the hole 3 is formed on the finished product 1 by the drill, or the tap is formed in the through hole 2 or the hole 3. operation.

However, when the hole 3 is formed into a tap, since the accurate depth of the hole 3 cannot be grasped, the tap is moved to a depth deeper than the hole 3, so that a collision occurs at the front end of the hole, and the collision exceeds the rotational force. Torque, causing a break in a certain part of the tap. The tap does not match the size of the drill or the tap wears, or the material of the finished product is made of tool steel. When the machinability is not good, the tap breakage caused by the conflict with the raw material often occurs. Economic loss.

In addition, when the drilling machine or the tap breaks due to the torsion force during operation, the instantaneous breakage caused by the high-speed rotation causes the debris to be bounced to the outside with the rotational force, causing a safety accident.

More specific examples:

An embodiment of the present invention consisting of the structure will be described in detail with reference to Figs.

The tapping safety special torque tool according to the present invention performs the following operation: the connecting shaft 21 is clamped into the inner diameter of the lower side of the main shaft 87, and fixed, and combined with the chuck 88 of the lower side connecting tool to form a hole drilling machine or formed The tap is machined in the hole.

The spindle 87 is rotated by the power supplied from the bench drill 80 motor assembly 84, and the finished product 1 is fixed to the upper side of the table 82 to form any one of the through hole 2 and the hole 3, and is in the through hole 2 and the hole 3. Perform tapping at any position.

The rotary joystick 86 is rotated, and the spindle 87, which is rotated at a high speed, is moved downward, and the work required for the finished product 1 is performed by means of a tool coupled to the chuck 88.

When the tool combined with the chuck 88 performs the hole forming or tapping operation by high-speed rotation, when the operator rotates the joystick 86 to move the tool downward, a torque generated by the rotational force occurs on the tool, and the rotating force is generated by the rotating force. Torque to perform the work.

However, when the torque generated by the rotation of the tool is unbearable when performing drilling or tapping, the tool may be broken. However, the idle washer 40 can prevent the torque from being transmitted before the torque is applied to the tool and causes the break to prevent the tool from breaking.

When the rotational force transmitted from the main shaft 87 is raised to a torque value that the tool cannot withstand, the ball stop groove 14 formed on the blade 13 of the chuck connecting shaft 10 that rotates toward the main shaft 87 is combined with the ball guide groove 43 of the idle washer 40. The rotating guide ball 45 will pass over the ball stop groove 14. Therefore, although the main shaft 87 and the main shaft connecting rod 20, the elastic adjusting portion 30, and the idle washer 40 are rotated, the chuck connecting shaft 10 and the chuck 88 and the tool can be stopped to prevent the tool from being broken.

The power transmitted by the spindle connecting rod 20 isolates the rotation of the rotating guide ball 45 combined with the ball guiding groove 43 of the idle washer 40 to the power of the idle washer 40 and the chuck connecting shaft 10. Thereby, although the rotational force of the main shaft 87 can rotate the main shaft connecting rod 20 and the idle washer 40 at a high speed, it is transmitted to the chuck connecting shaft 10, so that the torque cannot be transmitted to the tool mounted on the chuck 88. Prevent the tool from breaking.

The rotation guide ball 45 mounted in the ball guide groove 43 of the idle washer 40 moves in conjunction with the outer diameter when the idle washer 40 is raised as it rises, separates, and idling from the ball stop groove 14 of the blade 13. The guide ball 42 is provided in a state of being coupled to the movement guide groove 25 in the axial direction, the idle washer 40 is not rotated, but is raised in the direction of the shaft, and the rotary guide ball 45 is lifted from the ball stop groove 14 and separated therefrom.

As described above, the idle washer 40 rises to isolate the transmission of the rotational force, prevents the tool 86 from being reversely rotated, and causes the tool to be separated from the finished product 1, and the elasticity of the spring 70 provides elasticity to the idle washer 40, performing the next use of the tool. At the time of the operation, the rotation guide ball 45 of the idle washer 40 is combined with the ball stop groove 14 of the blade 13 to rotate together.

The pressure gauge 29 is mounted on the outer diameter of the main shaft connecting rod 20, and adjusts the torque according to the rotation of the elastic adjusting portion 30.

If the elastic adjusting portion 30 is rotated, since the inner diameter screw 33 is coupled with the outer diameter screw 23 of the spindle connecting rod 20, the pressure gauge 29 is rotated at the outer diameter and moved to the upper side and the lower side, so that the torque can be visually confirmed and adjusted. .

When the torque is adjusted by the pressure gauge 29, if the elastic adjusting portion 30 is rotated, the elastic adjusting portion 30 presses the elastic adjusting pin 60 located at the outer diameter of the connecting shaft 21, and the elastic adjusting pin 60 descends from the pin through hole 22 along the cylindrical direction. The elastic adjusting washer 50 is pressed downward, and the elastic adjusting washer 50 is lowered while compressing the spring 70 to increase the elastic force and increase the torque.

If the elastic adjusting portion 30 is rotated in the reverse direction, the elastic adjusting portion 30 raises the elastic adjusting pin 60 located at the outer diameter of the connecting shaft 21 while rising, at which time the elastic adjusting pin 60 rises from the pin through hole 22 along the cylinder The direction-up elastic adjusting washer 50 is raised, and the elastic adjusting washer 50 is raised while reducing the elasticity of the spring 70 while reducing the torque value.

As described above, the torque value is controlled by the rotational elastic adjusting portion 30; and the torque value is conveniently adjusted by the pressure gauge 29 similarly formed on the outer diameter of the spindle connecting rod 20, and the tool torque value is appropriately selected to prevent the tool from being broken.

According to Figs. 14 and 15 of the present invention, the spindle connecting rod 20 is formed in a connected form by forming a hole in the inner diameter to be coupled to the main shaft 87. In the process of performing the work of the finished product 1 such as a drill machine and a tap, if a larger size drill is used, the rotary elastic adjustment portion 30 lifts the idle washer 40 so that the upper side of the brake block 41 and the elastic portion are not required to isolate the torque. The lower side contact of the washer 50 is adjusted.

In this way, during the operation of the rotary tool, the rising action of the idle washer 40 caused by the difference in torsion between the main shaft 87 and the chuck 88 can be isolated, so that the operation can be performed without isolating the power, and can be operated according to requirements. The torque tool is not installed and is always used in the installed state.

On the other hand, the present invention is applicable to bench drills, general-purpose milling machines, general lathes, vertical drilling, MCT, etc., and can perform drilling machine and tap operation without replacing the torsion system, and can also be set without depth. Under the circumstances, the tapping operation is not carried out, and at the same time, the damage caused by the processing load caused by the wear of the tap and the cutter blade can be prevented, and the tool in the drilling machine and the tap operation caused by the problem of removing the drill bit can be prevented from being damaged; In the case where the glove is wound into the device, it can also rely on the torque to stop the operation of the device, providing a safe and very useful invention.

Another embodiment of the present invention will be described in more detail below with reference to Figs. 17 to 35.

The present invention performs the following operations: a drill machine that mounts a tap to form a hole with a collet nut 122 at the lower end of the torsion shaft 121 or a work of processing a tap in the formed hole.

The power rotary torsion chuck chuck 130 and the safety torque chuck 110 provided by the MCT are used to fix the finished product to the upper side of the table to form any one of the through hole and the hole, on any one of the through hole and the hole. Perform the tapping operation.

The high-speed rotating safety torque chuck 110 is lowered, and the work required for the finished product is performed by taps. The tap is formed during the high-speed rotation while the hole is being formed or is in the process of operation, and the rotation force is generated according to the falling of the process tap. Torque, the work is performed by the torque formed by the rotation.

When the torque generated by the rotation of the tap is performed in the drilling or tapping operation, if the unbearable condition occurs, the tap breakage may occur. However, after the torsion force is generated on the torsion shaft 121, if the torsion force generated before the tap breaks passes through the safety steel ball 116 and exceeds the elasticity of the spring 114, it will move from the safety groove 121a and the majority of the tumbler metal plate 117 tumbler hole 117a. A small part moves, because the power transmission safety torque chuck 110 will continue to rotate, the torsion shaft 121 will stop, preventing the tap from rotating, thereby preventing breakage.

That is, by the tap, the power of the main rod 111 is used, and the operation of the tap is performed while the torsion shaft 121 is rotated, and if the set torque value abnormality occurs during the tap operation, the safety steel ball 116 and the spring 114 cannot rotate the main rod 111. The force is transmitted to the torsion shaft 121, which provides a stagnant state to the torsion shaft 121, and functions to prevent the tap from breaking.

The described safe torque action can be directly applied during manual tapping operations. However, if the tapping operation is performed automatically, the set tapping depth will be reached. If the machining condition is not predicted before, the Z axis will continue to move in the working direction when overload occurs on the tap, so to prevent The tap breaks and slides in the Z-axis direction to compensate for the error value.

That is, the main rod 111 is lowered in the Z-axis direction to perform the tapping operation, and the torsion force is generated in the middle. When the tap is about to break, the outer diameter guiding shaft 132 is coupled with the outer diameter chute guiding groove 137 of the main body 131 of the torsion chuck chuck 130. The diameter guiding steel ball 136 is lowered in the Z-axis direction to correct the Z-axis error value (see FIG. 22), and the torsion force occurs during the process of the main rod 111 rising after the end of the tapping operation in the Z-axis direction, and the tap is to be broken, and The inner diameter guide guide groove 133 formed by the inner diameter of the lower side inner diameter of the torsion chuck chuck 130 is coupled, and the inner diameter guide steel ball 134 fixed to the main rod 111 rises along the Z-axis direction, and By correcting the Z-axis error value (see FIG. 23), the torque chuck chuck 130 is raised and lowered according to the tapping operation step, and provides a safety for correcting the Z-axis falling error value and the rising error value even if a torque that can break the tap occurs. Spring pad device prevents breakage of the tap.

When the main rod 111 descends along the Z-axis direction, the inner diameter of the main body 131 and the upper oil-free bushing 139 and the outer diameter guiding shaft 132 provide an elastic correction error value, and the outer diameter spring 138 is reset if the main rod 111 When rising in the Z-axis direction, the inner diameter spring 140 is supplied with elasticity by the inner diameter bolt 141, and is compensated for the error value and then reset.

Therefore, when the tap is broken due to the torsion force during the tapping operation, the safe torque chuck 110 can stop the rotation of the tap, prevent the transmission of power, and protect the tap and the processed product and the tool. The torsion chuck chuck 130 can play a protective role, that is, in the process of the MCT and the universal compound milling machine according to the process operation, the axial Z-axis is driven, and when the torque is generated before the tapping operation is completed, the compensation is about ±15 mm. The Z-axis rise and fall error values protect the workpiece and tool from breakage while the tap continues to move.

The torque adjusting nut 112 is a fitting for adjusting a torque value by a nut 12a coupled to the main rod 111 bolt 111a. The rotating torque adjusting nut 112 rotates and lowers the torque adjusting nut 112 to lower the position control pin 114a, thereby causing application to the safety steel. The pressing force on the ball 116 rises. When the torque adjusting nut 112 is rotated, the position projection 114b of the position control pin 114a intersects with the rotation preventing groove 112b formed inside the torque adjusting nut 112 to provide a position for adjusting the torsion, and the position control pin 114a The erecting is performed in a state of penetrating the pin 113a through the spring cap 113, so that the upper side of the spring 114 ensures stable positioning, and the torque is more conveniently adjusted.

Further, the tumbler hole 117a for preventing the hammering of the metal plate 117 can function as follows. The safety steel ball 116 provides a torsion force in the large tumbler hole 117a. If the set torque is exceeded, the safety steel ball 116 moves in a small direction to the tumbler hole 117a, so that the main rod 111 rotates with the torsion shaft 121 without being subjected to a torque.

Industrial Applicability: The present invention is used on a bench drill using a drill and a tap, and a torque tool is installed between the spindle and the chuck, and the torque value applied to the tool when the tool is used reaches the set value and is immediately broken. The idle washer moves and isolates the rotational force to stop the chuck with the tool, only the part of the spindle and the torsion tool is idling to prevent the tool from breaking, and the idle spacing of the idle washer raises the idle washer to prevent collision with the moving guide ball. Prevents noise and subtle impacts, ultimately protecting the tool.

By using the rotational force generated when the tap is working, the power is isolated before the tap is broken due to the torsion force, the tap and the processed product and the tool are protected, and the setting value of the tapping operation is raised and lowered, and the movement is compensated when the tap is stopped. The Z-axis rise and fall error values provide a safe torque tool for taps that protects workpieces and tools from breakage.
