[0002] In the fields of semiconductor manufacturing and other precision machining, a vacuum contactor is a common workpiece clamping and fixing device. The exhaust pipe of a vacuum contactor is usually used to connect the vacuum contactor and a vacuum pump, for discharging the extracted gas and maintaining the required vacuum pressure. These exhaust pipes need to have certain sealing performance and characteristics of high temperature resistance and corrosion resistance to ensure that the system can operate effectively and maintain a stable vacuum environment.

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0019] Specific implementation cases:

[0020] As Figure 1 shown, a continuous blanking device for the exhaust pipe of a vacuum contactor includes a frame 1, on which a pressing part 2 is slidably installed, a clamping part 5 is installed on the frame 1, a cutting part 3 is installed on the clamping part 5, and a blanking part 4 is installed on the clamping part 5;

[0021] Among them, the pressing part 2 can move linearly along the frame 1, and the clamping part 5 can move linearly along the frame 1;

[0022] During operation, the exhaust pipe to be processed is placed into the clamping part 5 for the first step of simple clamping and centering, and the exhaust pipe to be processed is clamped and moved forward. The pressing part 2 slides forward along the frame 1 and is placed at the length position of the exhaust pipe to be blanked. The inner wall of the exhaust pipe to be processed conveyed by the clamping part 5 is pressed and clamped for the second step of clamping. Subsequently, the exhaust pipe to be processed is cut by the cutting part 3, and the exhaust pipe at this stage falls into the blanking part 4. The clamping part 5 can move linearly along the frame 1, and its function is to adjust the length of the blanked exhaust pipe;

[0023] As Figure 2 shown, the pressing part 2 includes a positioning and clamping mechanism 21, which is fixedly installed on the pressing part 2, and the horizontal position of the positioning and clamping mechanism 21 is adjustable;

[0024] The cutting part 3 includes a rotating mechanism (not shown in the figure). A cutting knife 31 is installed on the rotating mechanism. The cutting knife 31 is provided with several groups and is annularly distributed in the rotating mechanism. The driving mode of the rotating mechanism is cylinder driving;

[0025] The clamping part 5 includes a clamping mechanism (not shown in the figure). A clamping head 51 is installed inside the clamping mechanism. The clamping head 51 is a rotatable runner. The driving mode of the clamping mechanism is cylinder driving;

[0026] Among them, the driving mode of the rotating mechanism is cylinder-driven rotation, and the driving mode of the clamping mechanism is cylinder-driven linear movement forward or backward;

[0027] The rotating mechanism of the cutting part 3 is a rotating machine head controlled by a cylinder. The internal mechanism controlled by the cylinder is a prior art and will not be described in detail here. The cutter 31 installed inside is controlled to rotate by the rotating mechanism and can be gradually extended during processing by the cylinder control, and the exhaust pipe can be punched with the rotating mechanism;

[0028] The main function of the clamping part 5 is to position and preliminarily clamp the exhaust pipe to be processed and to transport the exhaust pipe to be processed. The clamping mechanism is controlled by the cylinder to extend inward at the same time, and two sets of relatively symmetrical clamping heads 51 are used to center and clamp the exhaust pipe to be processed.

[0029] like Figure 3 As shown, the positioning clamping mechanism 21 includes a connecting frame 218, a fixed shaft 213 is installed at the central axis of the connecting frame 218, four groups of transmission blocks 217 are arranged in the connecting frame 218, the transmission block 217 can slide horizontally in the connecting frame 218, the inner side of the transmission block 217 is an inclined surface, a fixed push frame 216 is installed on the fixed shaft 213, and four groups of abutment protrusions are provided on the fixed push frame 216 for pushing the transmission block 217 to slide along the inner inclined surface of the transmission block 217, and abutment blocks 219 are installed on the outer side of the transmission block 217. The outer side of 9 is an arc-shaped surface, a limit frame 212 is installed below the connecting frame 218, a connecting block 210 is installed below the fixed shaft 213, a spring 215 is installed on the connecting block 210, and the spring 215 conflicts with the limit frame 212; in order to make the fixed push frame 216 push the transmission block 217 to slide more stably, there are four groups of abutting protrusions on the fixed push frame 216, and sliders (not marked in the figure) are arranged at the front end, and a slide groove (not marked in the figure) is arranged in the transmission block 217, and the slider (not marked in the figure) and the slide groove (not marked in the figure) are slidably connected;

[0030] A plane bearing (not shown in the figure) is provided at the connection between the connecting frame 218 and the limiting frame 212, a bearing 214 is provided at the connection between the limiting frame 212 and the fixed shaft 213, a limiting rod 211 is provided on the connecting block 210, and the limiting rod 211 is slidably connected with the limiting frame 212. The limiting rod 211 between the connecting block 210 and the limiting frame 212 makes the limiting frame 212 not rotate but move up and down along the limiting rod 211, and the plane bearing (not shown in the figure) and the bearing 214 are used to prevent the limiting frame 212 from rotating with the rotation of the fixed shaft 213 and the connecting frame 218;

[0031] For the convenience of description, the mechanism has an initial state, in which the spring 215 contacts the limit frame 212, the slider (not shown) is at the rear end of the slide slot (not shown), and the abutment block 219 contracts and is in close contact with the surface of the connecting frame 218;

[0032] When working, after the clamping part 5 completes one clamping, the motor controls the pressing part 2 to move along the direction defined by the frame 1 to a specified position and fix it. The inner wall of the exhaust pipe is sleeved outside the connecting frame 218 until the limiting frame 212 abuts against the top wall of the exhaust pipe. Under the force of the continuous forward movement of the motor on the clamping part 5, the limiting frame 212 moves backward along the limiting rod 211. The fixed shaft 213 and the fixed pushing frame 216 remain stationary, driving the limiting frame 212 to drive the connecting frame 218 to move backward along the fixed shaft 213. The sliding groove (not marked in the figure) in the hypotenuse of the transmission block 217 slides along the slider (not marked in the figure) on the direction contact head of the fixed pushing frame 216. The transmission block 217 expands outward along the hypotenuse along the groove arranged in the connecting frame 218, pushing the contact block 219 to expand outward. The spring 215 contracts and presses the limiting frame 212 to increase the clamping force until the contact block 219 is in close contact with the inner wall of the exhaust pipe to complete centering clamping;

[0033] Subsequently, the cutting part 3 rotates and cuts the clamped exhaust pipe. After the cutting is completed, the clamping part 5 moves backward, and the spring 215 adaptively returns to its original state, pushing the limiting frame 212 to make the contact block 219 contract until it returns to the initial state;

[0034] After the processing of the exhaust pipe is completed, with the withdrawal of the clamping part 5, the positioning and clamping mechanism 21 returns to its original state. The exhaust pipe falls into the blanking part 4 and is collected. When processing the next section, the clamping part 5 conveys the exhaust pipe to be processed forward to perform the next round of blanking;

[0035] In summary, the two relatively symmetrical clamping heads 51 of the clamping part 5 are used to center, position and clamp the exhaust pipe to be processed. Then, the motor controls the pressing part 2 to move closer to the exhaust pipe to be processed along the direction defined by the frame 1, so that the limiting frame 212 is pressed down by the pipe wall of the exhaust pipe and drives the connecting frame 218 to move backward along the fixed shaft 213, pushing the contact block 219 to expand outward, realizing the clamping during the continuous blanking process by tightly attaching to the inner wall of the exhaust pipe. After the processing is completed, with the withdrawal of the clamping part 5, the positioning and clamping mechanism 21 returns to its original state. The exhaust pipe falls into the blanking part 4 and is collected. When processing the next section, the clamping part 5 conveys the exhaust pipe to be processed forward to realize continuous blanking.

[0036] The above is only the preferred implementation mode of the present application. The protection scope of the present application is not limited to the above embodiments. All technical solutions within the scope of this idea belong to the protection scope of the present application. It should be pointed out that for those of ordinary skill in the art in this technical field, several improvements and refinements made without departing from the principle of the present application should also be regarded as within the protection scope of the present application.
