Detailed Implementation

[0023] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0024] Please see Figures 1-6 This application provides a quick-change device for oilfield-specific cutting tools in a machining center, including a machining table assembly 10 and a machining assembly 20.

[0025] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6The machining table assembly 10 includes a machining table 110, on which a workpiece clamping table 140 is provided. A placement groove 141 is provided at the center of one side of the workpiece clamping table 140. The workpiece clamping table 140 has several T-shaped sliding grooves 142 arranged in a circular array and communicating with the placement groove 141. A fixing ring 150 is fixedly connected to the outer side of the workpiece clamping table 140. Several clamping members 160 are arranged in a circular array on the fixing ring 150. The clamping end of each clamping member 160 is slidably disposed on each The T-shaped groove 142 contains a clamping member 160. Rotating this member inserts the tool into the placement groove 141. Rotating the clamping member 160 again ensures it presses firmly against the outside of the tool, thus limiting its movement. When machining tools of different specifications, all clamping members 160 are rotated sequentially to place the tool into the placement groove 141. Each clamping member 160 is then rotated sequentially until it presses firmly against the outside of the tool, thus limiting and fixing its position. The clamping members 160 provide more stable tool positioning, preventing wobbling during cutting and improving tool accuracy. This design allows for limiting the movement of tools of different specifications, enhancing the practicality of the invention and enabling faster tool changing and clamping, thereby increasing machining efficiency.

[0026] In this embodiment, each clamping member 160 includes a knob 161, with a threaded rod 162 fixedly connected to the knob 161. The other end of the threaded rod 162 is threaded through the fixing ring 150 and rotatably connected to a T-shaped clamping block 163, which is slidably disposed inside the T-shaped groove 142. Rotating the knob 161 causes the threaded rod 162 to rotate, thereby allowing the T-shaped clamping block 163 to either press against or move away from the tool.

[0027] In the specific configuration, the height of each T-shaped clamping block 163 increases sequentially from the end closest to the threaded rod 162. This results in a larger contact area between the T-shaped clamping block 163 and the tool, thereby making the clamping of the tool more stable.

[0028] In this embodiment, a fixed base 170 is installed on the processing table 110, and a first cylinder 130 is installed on the fixed base 170. The cylinder rod end of the first cylinder 130 is fixedly connected to the workpiece clamping table 140. A U-shaped plate 120 is fixedly connected to the processing table 110. A movable component 180 is installed inside the U-shaped plate 120. A clamping component 190 is connected to the movable end of the movable component 180, and the clamping component 190 is located between the workpiece clamping table 140 and the processing assembly 20. The fixed base 170 is installed on the U-shaped plate 120. The movable component 180 includes a handle 181, and a long screw 182 is fixedly connected to the handle 181. Two connecting seats 183 are fixedly connected inside the U-shaped plate 120. The long screw 182 is rotatably connected to the two connecting seats 183 respectively. The clamping component 190 is screwed to the long screw 182. The clamping component 190 includes a base plate 191, which is screwed to a long screw 182. A lifting part 192 is mounted on the base plate 191, and a clamping part 194 is mounted on the lifting part 192. A pushing part 193 is slidably connected to the base plate 191, and the bottom end of the lifting part 192 is connected to the pushing part 193. By rotating the handle 181, the long screw 182 moves, which in turn moves the base plate 191, allowing the detection element on the clamping part 194 to move. The position of the detection element can be adjusted according to the actual size of the cutting tool, facilitating tool inspection. The first cylinder 130 moves the workpiece clamping table 140, facilitating the machining assembly 20 to process the cutting tool.

[0029] Please see Figure 1 The machining assembly 20 is mounted on the machining table 110 and processes the workpiece inside the placement slot 141. Once the cutting tool is fixed, the machining assembly 20 is activated to perform the machining. The specific structure and machining principle of the machining assembly 20 are existing technologies and will not be described in detail here.

[0030] The working principle of the quick-change device for oilfield cutting tools in this machining center is as follows: Rotating a clamping element 160 inserts the tool into the placement slot 141. Rotating the clamping element 160 again causes it to press firmly against the outside of the tool, thus limiting its position. When machining tools of different specifications, all clamping elements 160 are rotated sequentially to place the tool into the placement slot 141. Each clamping element 160 is then rotated sequentially until it presses firmly against the outside of the tool, thus limiting and fixing its position. The clamping elements 160 provide more stable tool positioning, preventing wobbling during cutting and improving tool accuracy. This device can limit the position of tools of different specifications, enhancing the practicality of this application. Furthermore, it allows for faster tool changing and clamping, improving machining efficiency.

[0031] It should be noted that the specific model and specifications of the first cylinder 130 need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail here.

[0032] The power supply and principle of the first cylinder 130 are clear to those skilled in the art and will not be described in detail here.

[0033] The above description is merely an embodiment of this application and is not intended to limit the scope of protection of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application. It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
