Abstract

A pneumatic rotary tool has a housing formed primarily from plastic so that the weight and price of the tool are substantially reduced. The air motor is formed for economic assembly while permitting greater structural stability should the housing deflect under an impact. The tool includes a torque selector which controls the amount of pressurized air allowed to enter the air motor, thereby controlling the torque output of the motor. The user may adjust the torque selector to a number of set positions which correspond to discrete torque values. The tool additionally incorporates early and late stage exhaust ports, so that backpressure within the air motor does not slow motor rotation or decrease tool power.

Description of the invention (1 Background of the invention The present invention relates to a tool for fasting βn ticks, and more particularly a plastic case with a plastic case and a variable 杻 a. Please read the note on the back first Please fill in this page again. This page ^ We are working hard to improve the air pressure rotary tool that uses pressurized air efficiently. The present invention is particularly related to the use of rotary ^, which has a conventional output shaft to rotate, such as a A power tool such as a bolt or a nut that fastens 1 TL 彳 thousand. This type of tool is usually used for automated maintenance and industrial purple brigade "^ • Gongguo application. Traditionally, pneumatic rotary workers include a number of metals A metal shell for U 4 pieces of clothing. These tools will be strong due to their metal structure. They are strong and durable, but the all-metal structure will make them a bit heavy and expensive. Flow through the tool and X tools & lt Pressurized 2 gas will power the tool. When the air expands in the tool, it will cause an internal motor movement to drive the tool. The Central Consumers' Bureau of the Ministry of Economic Affairs will print the tool system. One of the aims of the creators was to provide a pneumatic rotary tool that is as durable as an all-metal tool, but uses a portion formed of a lighter material such as plastic to appropriately reduce the weight and cost of the tool. Design this One of the difficulties in tools is that plastic has a reduced rigidity compared to strong metals such as steel. For example, once a plastic tool is on a hard surface, the air motor of a metal in the tool will move and Relative to the casing and the output shaft are under-aligned or tilted, making the tool unusable. This problem will cause the tool maker to produce a complicated internal motor cover to prevent the motor from tilting in the casing. For example, the US patent No. 5,346, 〇24 (Geiger et al.) Disclosed such a motor cover described as a motor_cylinder 15. The cover is a κ-pillar type, including a plurality of P pieces such as _back cover 26 and inner hole 27 The end is also extended from the closed end. The cylinder and the back cover -4- This paper size is suitable for gg home (CNS) A4 specification (210 X297 mm) 1245692 Α7 Β7… in the manufacture-closed end gas red more Difficulties Printed by the Consumer Cooperatives of the Central Standards Bureau of the Ministry of Economic Affairs 5. Description of the invention (2) The inner hole system is a single structure ..... ~ 'and it is difficult to reinforce. Therefore, it is very vocal to manufacture such covers, which will cultivate ^ When using lighter and lower cost materials such as plastic temple materials to make other parts, Ding Shi / Γ has an excellent cost. For this reason, it is extremely necessary to inexpensively form a tool from both lightweight materials and metal parts. / In addition, the rotating tool it knows often combines a plurality of _ structures to adjust the torque according to the user's input. One of these tools uses the back pressure in the air motor to adjust the torque output. When the When the back pressure increases, the torque output of the 唁 motor will decrease. Since this design uses pressurized air 2 to get large " no action " to drive the tool to operate at maximum power, it is light and inefficient. At the low power setting, a large portion of the air will bypass the motor to back pressure the motor 'without increasing the power of the tool. Accordingly, there is a need for a work that can adjust torque more efficiently by using less pressurized air. A typical two-air motor is a combination of a plurality of blades that can react with pressurized air to cause the motor to rotate. Pressurized air storage capsules are received in a volume defined by adjacent vanes. Conventional rotating tools typically have a single discharge orifice in the air motor to discharge pressurized air from the motor. When each rotor chamber passes through the exhaust port, a large amount of air in the chamber will pass through the exhaust port and leave the motor. Any air remaining in the container after the container passes the discharge opening will accumulate in the container. The volume of the chamber and I1 are reduced as the valley main approaches a redundant motor cycle. Compressing the air in the volume (back pressure) will reduce the speed of the rotating rotor. The back lip reduces the motor rate. Therefore, a pneumatic rotating tool that can reduce the back pressure loss in the 2 air motor is needed. -5- This paper size applies to China National Standard (CNS) Α4 specification (210X297 mm)

In addition, the outer layer of a soft material, preferably made of rubber, is covered with a plastic handle and molded on the handle 7 丨. A preferred cover molding procedure is to form the outer layer 73 directly on the handle 7 丨, which fuses the outer layer to the surface of the handle and provides the user with a stronger handle surface. The cover molding procedure requires a mold that is slightly larger than the handle 7 丨, so that the space between the handle and the mold accommodates a flowable rubber material that forms the exterior of the handle after hardening the foot. Floor. Since the outer rubber layer 73 is directly fused to the handle 71, this layer will fit tightly on the handle without the need for further holding means. This close fit will assist the external layer 73 to be held on the handle 7 1 during the use of the tool 51 so that the user can hold the tool firmly without movement between the handle and the external layer π after the input port 8 1, 2 The gas will pass through a tilt valve 95 and the tilt valve 75 can be opened by pulling the trigger valve 75 (Fig. 3).

The end cap 5 9 additionally includes a directional socket 14 7 (FIG. 10) for receiving one of the directional pins 14 9. The directional pins extend from the end cap 59 to receive a plurality of tool assemblies and orient the tool assemblies relative to each other. Due to the directional pins 49, the plurality of tool components are properly aligned and oriented relative to each other to ensure that the β tools are properly grouped and move with each other. The components for receiving and receiving the directional pins 149 will be discussed in more detail below. Scroll to Figure 11 and Figure! 2. The arrow indicator 145 indicates a setting of 2. Among them, one of the torque selectors 8 5 and the first orifice 1 5 1 are aligned with one of the lower portions 153 of the first passage 1 1 7 and one of the torque selectors The second, larger aperture 155 is aligned with an upper portion 1 5 7 of one of the first passages. In this structure, some air will bypass the fixed orifice 143 and pass to the upper portion 157 of the first passage 117. More specifically, the air passes through the lower part 1 53 of the first passage 1 1 7, the first orifice 151, a selector passage 163, the second orifice 155 and finally enters the upper part of the first passage 1 5 7 . At the same time, air will continue to pass through the fixed orifice 143 in this first setting. That is, the total air holding through the first passage 117 to the air motor Π9 is the total air passing through the torque selector 85 and the fixed orifice 143. Similar to the fixed aperture 1 43, the first aperture 1 5 1 controls the amount of air moving through the first passage 117 to suppress the power of the tool.

Description of the invention (The tool is gripped when it is intermittently impacted to the output shaft 57. Since those who are familiar with this skill are already familiar with the Moro mechanism 1 3 1, it will not repeat its details. Supporting the shaft 213 series In one of the second ball bearings 233 installed in the second end cap 181 (Figure 3). The slotted shaft 21 5 and the support shaft 2 13 extend substantially along a cylindrical shaft b of the rotor 175, and two The group of ball bearings 225 and 233 allow the rotor to rotate freely in the passage sleeve 173. The shaft B of the rotor 175 is eccentrically disposed with respect to the center axis of the passage sleeve 1 73 and has a plurality of longitudinal channels 23 that can accommodate the blades 1 77. 5 (Figure 17). The vane 177 is formed of a light weight material and fits loosely in the channel 235, so that the end caps. 179, 181 and the passage sleeve 173 restrict the vane 1 77 to the inner edge of the air motor 1 1 9 It moves longitudinally with the tool. When the rotor 1 7 5 rotates, the rotor 1 5 extends radially outward from the rotor to contact the inside of the passage sleeve 1 7 3. The adjacent blade 1 7 7 is in the motor Π. A plurality of i-cavities 23 7 are generated in 9 to accommodate compressed air when the rotor 1 75 rotates. Each cavity 23 7 is composed of The front vane 177 and a rear vane are defined, and the front vane is adjacent to the rear vane when the rotor 175 rotates. When the cavity 237 passes through an input aperture 247 d plane, the compressed air will compress the front vane 丨 7 7 As a result, the rotor 175 is rotated. When the air runs through the air motor 119, the rotor 75 will rotate to cause the three phases of the air cavity 237: a power phase, a discharge phase and a recovery phase (Figure 17). The air system moves from the torque selector 85 to an intake manifold 247. The pressurized air is then forced through an input port 245 formed in the intake manifold 247 to allow air to move into the rotor 75 and the passage sleeve. In the cavity 237 between 173, this dynamic-force phase will begin. When the pressurized air pushes the front blade 177, the force applied to the blade will move the rotor π in the direction indicated by the arrow f When the air volume expands in the cavity 237, the rotor-19- This paper size applies the Chinese National Standard (CNS) specifications (210X297 mm) Printed by the Consumer Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs 1245692 A7 Five 'Invention Description (17 175 will turn to increase Wait for the volume of space between the blades 177. The blades continue to move outward in their channels 235 to maintain a seal between the blades and the channel sleeve 173. When the power phase ends, the space The volume of the cavity 237 gradually increases to its maximum amount, and the front vane 177 will pass through one of the passage sleeves 173 and the support sleeves 17 to discharge the orifice 25 1 at an early stage (Figures 17, 21, 27 and 28). These orifices 2 5 1 indicate the transition between the power stage and the discharge connection to allow the expanded 2 gas to leak from the inside of the 2 air motor 1 1 9 to the gap space between the air motor and the casing 53 A lower pressure area in 252. The radon leaving these holes 25 j will be discharged from the tool 51 as described below. The volume of the cavity 2 3 7 during an initial part of the discharge phase is greater than any other time in the cycle, the body system expands to a maximum volume and then begins when the cavity moves past the bottom of the motor 119 cut back. When the rear blade 77 passes through the orifice 25 1 in the initial stage, some air remains in the air motor 1 19 in front of the rear blade. When the rotor 175 continues to rotate, the volume of the cavity 237 will decrease and increase the air pressure in the cavity. Compressing the air will generate a back pressure in the motor 9 and lose the energy of the rotating rotor 175, slowing down the rotation of the rotor. To alleviate the back pressure generated in the rotor 1 1 9, the end of the discharge stroke includes a final-stage discharge orifice 2 5 3 that allows the remaining air to leak from the air motor 1 1 9 into a discharge manifold 25 5 . The discharged air leaves the tool 51 again as described below. The discharge orifice 253 through the final stage represents the third stage of the transition to the motor 1 19, that is, the recovery stage, where the volume of the cavity 237 is at a minimum. This stage returns the air blades 177 to the beginning of the power stage so that the motor 119 can repeat its cycle. -20- This paper size applies to Chinese National Standard (CNS) A4 (210X297 mm) (Please read the precautions on the back before this page) — Binding and binding 1245692 A7 B7 V. Description of the invention &lt; 8) Central Printed by the Consumer Bureau of the Standard Bureau When the rotor 17: &gt; 'Rotor 177 is continuously moving radially inward and outward from the channel 235 in its channel 235 to fit the channel sleeve 丨 73 (Figure 丨 7 ). Although the rotation of the rotor 1 75 is to drive the blades 1 ′ radially outwards by its own rotation, after the rotor has started to rotate enough to push the blades of the blades outward by the rotation of the rotors, the blades Initially, the impedance can move outward in the radial direction. This problem will be exacerbated when the necessary lubricant is contained in the 2-air motor 119. The right vane 177 does not extend from its passage 137, so air can only flow through the air motor 1 1 9 to the initial stage discharge valve 25, and cannot rotate the rotor 175 as required. In order to counteract this effect, the first end cap 179 (FIG. 25 and FIG. 26) and the second end cap 181 (FIG. 22, FIG. 24) both include a vane inlet passage 261. Some of the pressurized air in the intake manifold 247 will flow through these blade channels 261 at either end of the air motor 19. The air moving in the channel 26 丨 behind the blade Π7 pushes the channel 235 outward, so that the air flowing through the motor 1 丨 9 can press the blades that extend. As the chi gas moves through most of this power stage, the blade intake passage 261 will carry this air to each blade 177. The air intake passage 261 ends once when the blades 1 77 approach the full extension from the passage 23 5. After the bucket 177 starts to move radially inward toward the axis of the rotor 175, the air behind the bucket must leak, so the bucket output channel 263 is formed on the first end cap 179 and the second end cap 181. This allows air behind the blades 177 to move through the passage 263 and into the exhaust manifold 255. This air is then discharged from the motor 1 1 9 in the same manner as the discharge vent 2 5 3 at the final stage of gas discharge. Let's discuss the exhaust air discharged from the exhaust port 25 1 at the initial stage. The air then flows through one pair of orifices (not shown) in the casing 53 and the pair of orifices is vented to the air in the handle 7 1. Port 9 1 (Figure 3). Discharge hole at the final stage-21-This paper size applies Chinese National Standard (CNS) M specification (21 () &gt; &lt; 297 Gongchu) ~ &quot; '— &quot; 1245692 Α7 Β7 V. Description of the invention (19) 253, or one of the two-blade outlet opening channels 263, and the exhaust air entering the exhaust manifold 2 5 5 will be exhausted from the tool 5 i through different paths (FIG. 4). This path guides the M working gas 4 through the first passage 1 2 丨 and returns to the rotary selector valve, wherein the valve can divert the air to the position where it can pass to the support sleeve 171 and the first end cap 179 and the machine. The remaining discharges of the two symmetrical overflow paths 269 (04) in the gap space 252 between the shells 53 are then run through these spaces 2 5 2 to the pair of orifices and together with the other discharge air, the air discharge port 91 is discharged. . In the reverse operation, the operation of the tool 51 is substantially the same except that the air bypass bypasses the torque selector 85. The air system enters the tool 51 through the same air inlet 81. Rotating the selector valve 83 diverts the air to the second passage 1 _ 1 where 4 2 gas runs upward through the tool 5 1 until it enters the discharge moss 2 5 5. This air then flows through the final discharge orifice 2 5 3 and enters the air pump 1 1 9. This air reacts here on the opposite side of the blade 丨 77, so it must apply force to the rotor 丨 7 in the opposite direction. 5. In the initial stage, the discharge orifice 25 1 operates in substantially the same manner as in the forward direction. Both the blade inlet passage 261 and the blade outlet passage 263 are the same as those described above, except that they allow air to flow in opposite directions.

Typically, a ‘pneumatic rotary tool’ is formed almost entirely of a high-strength metal such as steel. The tool is subjected to high stress and load under proper use plus intermittent impact due to drop or impact. Although metals such as steel provide adequate strength, one of the major disadvantages of a metal structure is its large weight and high material cost.
