Description

Technical Field

[0001] This invention relates to the field of machining centers, and more specifically to a power tool holder. Background Technology

[0002] A powered tool holder refers to a tool holder that is mounted on a powered tool turret and can be driven by a servo motor. This type of tool holder is generally used on mill-turn machines, and a few can also be used on machining centers with powered tool turrets.

[0003] The existing power tool holders have fixed positions for the tool and the tool holder during use, so they can only process a single specific position of the workpiece. When multiple positions of the workpiece need to be processed, the workpiece needs to be re-clamped. The repeated clamping of the workpiece will cause processing errors between the two stations. Furthermore, since the processing angle of the tool cannot be adjusted, it is not convenient to process the workpiece efficiently.

[0004] Therefore, it is necessary to invent a powered tool holder. Summary of the Invention

[0005] Therefore, the present invention provides a power tool holder. By pulling the pull rod downwards to the bottom of the slide groove, the second helical gear can be rotated as a whole, thereby changing the rotation angle of the output shaft and thus changing the working angle of the tool. After the rotation angle is changed, by pulling the pull rod upwards, the output shaft is rotated to make the tool work. This solves the problem that the existing power tool holders are not convenient for efficient workpiece processing due to the position of the tool and the tool holder.

[0009] Preferably, the adjusting assembly includes a pull plate, three sets of outer cylinder rods and the outer wall of the rotating shaft are all fixedly installed with circular clamps, and the four sets of circular clamps are located on the same vertical plane. The four sets of circular clamps are engaged with the pull plate, and the three sets of outer cylinder rods and the rotating shaft are rotatably connected to the pull plate through the circular clamps. A sliding groove four is opened in the middle of the outer wall of the end of the mating cylinder. The outer cylinder rod and the rotating shaft in the middle are located inside the sliding groove four and are slidably connected to the inner wall of the sliding groove four. Sliding grooves five are opened on both sides of the outer wall of the end of the mating cylinder. The two sets of outer cylinder rods on both sides are located inside the two sets of sliding grooves five and are slidably connected to the inner wall of the sliding groove five. A pull rod is fixedly installed on the right outer wall of the pull plate. A first end face gear is fixedly installed at the end of the rotating shaft, and a second end face gear is fixedly installed at the end of the outer cylinder rod in the middle.

[0010] Preferably, a power shaft is rotatably connected to the top of the outer wall of the outer sleeve end, and a third end face gear is fixedly installed on the end wall of the power shaft located inside the outer sleeve. The third end face gear meshes with both the first end face gear and the second end face gear. A sliding groove is provided on the outer wall of the end of the mating cylinder, and the pull rod is located inside the sliding groove and is slidably connected to the inner wall of the sliding groove.

[0011] Preferably, the deflection assembly includes a first helical gear, which has two sets and is rotatably connected to the inner wall of the deflection housing.

The front wall of the output shaft is fixedly connected to a three-grip chuck.

[0012] The beneficial effects of this invention are:

[0013] 1. When it is necessary to change the working angle of the tool, the user pulls the pull plate down through the pull rod to the bottom of the slide groove. At the same time, the user pushes the pull plate forward through the pull rod to engage the second end face gear with the third end face gear. Then, the drive shaft drives the third end face gear to rotate, so that the third end face gear engages with the second end face gear, thereby driving the gear two on the rotating rod component to rotate. This causes the gear two to engage with the two sets of gear one. At this time, the two sets of gear one rotate in the same direction, so that the first helical gear fixed to the gear one engages with gear six, and the gear six rotates in the opposite direction. At this time, the second helical gear cannot engage with the two sets of gear six. Therefore, when the two sets of gear six rotate, it can drive the second helical gear engaged with the two sets of gear six to rotate, thereby changing the rotation angle of the output shaft and achieving the purpose of changing the working angle of the tool. After the rotation angle is changed, the user pulls the pull rod down to engage the third end face gear with the first end face gear, and then the output shaft rotates to make the tool work.

[0014] 2. When the tool needs to work, the operator pulls the pull plate upwards using the pull rod. When the pull rod is pulled to the top of the slide groove, the pull plate is pushed forward using the pull rod. At this time, the first end face gear meshes with the third end face gear, the spring inside the outer cylinder rod is compressed, and both sets of gears mesh with gear one. This drives the power shaft to rotate the third end face gear, causing the third end face gear to mesh with the first end face gear. This rotates the shaft, causing gear five on the shaft to mesh with gear four, and causing the rotating rod component fixed to gear four to rotate. This, in turn, drives gear three at the front end of the rotating rod component to move forward. The rotation causes the two sets of gears to mesh, thereby driving the first gear, which is meshed with the two sets of gears, to rotate. At this time, the two sets of gears rotate in opposite directions, thereby driving the first helical gear, which is fixed to the two sets of gears, to rotate. At the same time, the two sets of first helical gears rotate in opposite directions. Then, the two sets of first helical gears mesh with the helical teeth on the outer side of the two sets of gears, thereby driving the two sets of gears to rotate in the same direction. This causes the second helical gear to mesh with the helical teeth on the inner side of the two sets of gears, causing the second helical gear to rotate. This, in turn, drives the three-jaw chuck to rotate, and further drives the tool held by the three-jaw chuck to work. Attached Figure Description

Detailed Implementation

[0024] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0025] See attached document Figure 1-8 The present invention provides a power tool holder, including a power tool holder mechanism 100 and a three-jaw chuck 200. The three-jaw chuck 200 is located outside the power tool holder mechanism 100 and connected to the power tool holder mechanism 100. The power tool holder mechanism 100 includes a deflection shell 101. A deflection component 130 is provided inside the deflection shell 101. A mating cylinder 103 is fixedly installed on the outer wall of the end of the deflection shell 101. An execution component 110 is provided inside the mating cylinder 103. An outer sleeve 104 is fixedly installed on the outer wall of the end of the mating cylinder 103. An adjustment component 120 is provided inside the outer sleeve 104.

[0026] The actuating component 110 includes two sets of gears 111, which are rotatably connected to the outer walls of the top two sides of the deflection housing 101. A second groove 112 is formed in the middle of the outer wall of the deflection housing 101, and two third grooves 113 are formed on the outer walls of the bottom two sides of the deflection housing 101. Rotating rod components 114 are slidably connected to the inner walls of both third and second grooves 112. A second gear 115 is fixedly installed on the outer wall of the front end of the rotating rod component 114 located in the middle. The second gear 115 is connected to the two sets of gears 111. Gear 116 is fixedly installed on the outer wall of the front end of the rotating rod component 114 on both sides. The two sets of gear 116 mesh with each other and respectively mesh with the adjacent gear 111. Gear 117 is fixedly installed on the outer wall of the middle part of the rotating rod component 114 on the right side. A rotating shaft 118 is provided inside the mating cylinder 103. Gear 119 is fixedly installed on the outer wall of the front end of the rotating shaft 118. Gear 119 meshes with gear 117. The two sets of gear 116 and gear 115 are located on the same vertical plane.

[0027] Furthermore, the rotating rod component 114 includes an outer cylinder rod 1141, gears 115, 116, and 117, all of which are fixedly connected to the outer wall of the outer cylinder rod 1141. A spring 1142 is fixedly installed on the inner wall of the bottom of the outer cylinder rod 1141. Limiting strips 1143 are fixedly installed on the inner wall of the outer cylinder rod 1141. There are four sets of limiting strips 1143 arranged in a circumferential array. An extension rod 1144 is slidably connected to the inner wall of the outer cylinder rod 1141. The outer wall of the extension rod 1144 has four sets of limiting slides 1145 and four sets of limiting... The slide rail 1145 is slidably connected to four sets of limiting strips 1143. Specifically, when the outer cylinder rod 1141 rotates, the cooperation between the limiting strips 1143 and the limiting slide rail 1145 can drive the extension rod 1144 to rotate synchronously. In particular, when the pull plate 124 is pushed forward by the pull rod 125, the spring 1142 inside the outer cylinder rod 1141 is compressed. Under the reaction force of the spring 1142, the first end face gear 126 or the second end face gear 127 and the third end face gear 141 are more tightly engaged.

[0028] Furthermore, the adjusting assembly 120 includes a pull plate 124. Circular clamps 123 are fixedly installed on the outer walls of three sets of outer cylindrical rods 1141 and the rotating shaft 118, with all four sets of circular clamps 123 located on the same vertical plane. All four sets of circular clamps 123 engage with the pull plate 124, and the three sets of outer cylindrical rods 1141 and the rotating shaft 118 are rotatably connected to the pull plate 124 via the circular clamps 123. When the position of the pull plate 124 is changed by the pull rod 125, it can drive the outer cylindrical rods 1141 and the rotating shaft 118 connected to the pull plate 124 to move synchronously. Simultaneously, the pull plate 124 does not affect the rotation of the outer cylindrical rods 1141 and the rotating shaft 118. A sliding groove 121 is provided in the middle of the outer wall at the end of the mating cylinder 103. The outer cylindrical rods 1141 and the rotating shaft 118 in the middle are located inside the sliding groove 121 and are slidably connected to the inner wall of the sliding groove 121. The outer wall at the end of the mating cylinder 103 is also provided with... A slide 122 is provided, and two sets of outer cylindrical rods 1141 on both sides are located inside the two sets of slide 122 and are slidably connected to the inner wall of the slide 122. A pull rod 125 is fixedly installed on the outer wall of the right side of the pull plate 124. A first end face gear 126 is fixedly installed at the end of the rotating shaft 118, and a second end face gear 127 is fixedly installed at the end of the outer cylindrical rod 1141 in the middle. Specifically, by pulling the pull plate 124 upward by the pull rod 125, when the pull rod 125 is pulled to the top of the slide 105, the drive shaft 140 drives the third end face gear 141 to rotate, causing the second helical gear 136 to rotate. By pulling the pull plate 124 downward by the pull rod 125, when the pull rod 125 is pulled to the bottom of the slide 105, the drive shaft 140 drives the third end face gear 141 to rotate, causing the position of the second helical gear 136 to change.

[0029] Furthermore, a power shaft 140 is rotatably connected to the top of the outer wall of the outer sleeve 104. A third end face gear 141 is fixedly installed on the end wall of the power shaft 140 located inside the outer sleeve 104. The third end face gear 141 meshes with the first end face gear 126 and the second end face gear 127. A sliding groove 105 is provided on the outer wall of the end of the mating sleeve 103. The pull rod 125 is located inside the sliding groove 105 and is slidably connected to the inner wall of the sliding groove 105. Specifically, by driving the power shaft 140, it drives the third end face gear 141 to rotate, thereby enabling it to mesh with the first end face gear 126 and the second end face gear 127, which in turn drives the rotating shaft 118 and the rotating rod member 114 in the middle of the adjusting assembly 120 to rotate.

[0030] Furthermore, the deflection assembly 130 includes a first helical gear 131. Two sets of the first helical gear 131 are provided and rotatably connected to the inner wall of the deflection housing 101. The two sets of first helical gears 131 are fixedly connected to a gear 111 on the same side. When gear 111 rotates, it can drive the first helical gear 131 fixedly connected to gear 111 to rotate in the same direction. A support frame 132 is fixedly installed on the inner wall of the deflection housing 101. Gears 133 are rotatably connected to both sides of the support frame 132. The support frame 132 consists of two sets of gears. Gear 6 133 provides support. Both sides of gear 6 133 are provided with helical teeth 134. The two sets of helical teeth 134 on the outer side mesh with the two sets of first helical gears 131 respectively. A rotating frame 135 is rotatably connected to the outer side of gear 6 133 on the right side. The rotating frame 135 provides support for the second helical gear 136 and the output shaft 137. The second helical gear 136 is rotatably connected to the inner wall of the front end of the rotating frame 135, and the second helical gear 136 meshes with both sets of helical teeth 134 on the inner side. The output shaft 137 is rotatably connected to the outer wall of the front end of the rotating frame 135. 7. The output shaft 137 is fixedly connected to the second helical gear 136. A limiting groove 102 is provided on the front wall of the deflection housing 101. The limiting groove 102 provides a limit for the rotation of the output shaft 137. The output shaft 137 is located inside the limiting groove 102 and is slidably connected to the inner wall of the limiting groove 102. The front wall of the output shaft 137 is fixedly connected to the three-jaw chuck 200. Specifically, when the two sets of gears 133 rotate in the same direction, the second helical gear 136 engages with the helical tooth pattern 134 on the inner side of the two sets of gears 133. The meshing causes the second helical gear 136 to rotate, thereby driving the three-jaw chuck 200 to rotate, and further driving the tool held by the three-jaw chuck 200 to work. When the two sets of gears 133 rotate in opposite directions, the second helical gear 136 cannot mesh with the two sets of gears 133. Therefore, when the two sets of gears 133 rotate, they can drive the second helical gear 136, which is meshed with the two sets of gears 133, to rotate, thereby changing the rotation angle of the output shaft 137 and achieving the purpose of changing the working angle of the tool.

[0031] The usage process of this invention is as follows: When the tool needs to work, the user pulls the pull plate 124 upwards via the pull rod 125. When the pull rod 125 is pulled to the top of the slide groove 105, the pull plate 124 is pushed forward via the pull rod 125. At this time, the first end face gear 126 meshes with the third end face gear 141, and the spring 1142 inside the outer cylinder rod 1141 is compressed. At the same time, both sets of gears 116 mesh with gears 111. The drive shaft 140 drives the third end face gear 141 to rotate, thereby causing the third end face gear 141 to mesh with the first end face gear 126, driving the rotating shaft 118 to rotate, causing gear 119 on the rotating shaft 118 to mesh with gear 117, causing the rotating rod component 114 fixed to gear 117 to rotate, thereby driving the rotating shaft 118 to rotate. The gear 116 at the front end of the lever member 114 rotates, causing the two sets of gears 116 to mesh, thereby driving the gear 111 meshing with the two sets of gears 116 to rotate. At this time, the two sets of gears 111 rotate in opposite directions, thereby driving the first helical gear 131 fixed to the two sets of gears 111 to rotate. At the same time, the two sets of first helical gears 131 rotate in opposite directions. At this time, the two sets of first helical gears 131 mesh with the helical tooth pattern 134 on the outer side of the two sets of gears 133, thereby driving the two sets of gears 133 to rotate in the same direction. This causes the second helical gear 136 to mesh with the helical tooth pattern 134 on the inner side of the two sets of gears 133, causing the second helical gear 136 to rotate, thereby driving the three-jaw chuck 200 to rotate, and further driving the tool held by the three-jaw chuck 200 to work.

[0032] When the working angle of the tool needs to be changed, the user pulls the pull plate 124 downwards via the pull rod 125, moving the pull rod 125 to the bottom of the slide groove 105. Simultaneously, the pull plate 124 is pushed forward via the pull rod 125, causing the second end face gear 127 to mesh with the third end face gear 141. Then, the drive shaft 140 drives the third end face gear 141 to rotate, causing it to mesh with the second end face gear 127. This, in turn, drives the second gear 115 on the rotating rod component 114 to rotate, causing the second gear 115 to mesh with the two sets of gears 111. At this time, the rotation direction of the two sets of gears 111... The same applies, so that the first helical gear 131, which is fixed to gear 111, meshes with gear 133 and gear 133 rotates in opposite directions. At this time, the second helical gear 136 cannot mesh with the two sets of gears 133. Therefore, when the two sets of gears 133 rotate, they can drive the second helical gear 136, which is engaged with the two sets of gears 133, to rotate, thereby changing the rotation angle of the output shaft 137 and achieving the purpose of changing the working angle of the tool. After the rotation angle is changed, by pulling the pull rod 125 upward, the third end face gear 141 meshes with the first end face gear 126, and then the output shaft 137 rotates to make the tool work.

[0033] The above description is merely a preferred embodiment of the present invention. Any person skilled in the art can modify the present invention or modify it into an equivalent technical solution using the technical solutions described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solutions of the present invention fall within the scope of protection claimed by the present invention.
