Description

Technical Field

[0001] The invention relates to the field of flow channel plate nozzle sealing detection, and in particular to a new energy flow channel plate nozzle floating plugging mechanism. Background Art

[0002] Before leaving the factory, the new energy flow channel plate needs to be tested by air tightness testing equipment to simulate the sealing status during actual loading. The existing nozzle plugging mechanism, such as Figure 1 As shown, the sealing pad A is embedded in the sealing head B, and then connected and fixed with the sealing cylinder D through the connecting plate C. When sealing the nozzle of the new energy flow channel plate, the air tightness testing equipment first pushes the nozzle sealing mechanism to the nozzle of the new energy flow channel plate, and then extends it through the sealing cylinder D, driving the connecting plate C, the sealing head B, and the sealing pad A to move to support the nozzle of the new energy flow channel plate to be blocked, and the sealing test is achieved by squeezing the sealing pad A.

[0003] However, the existing sealing mechanism cannot effectively simulate the actual sealing state of the runner plate when it is installed, which may result in a good product during the sealing test but a defective part during actual installation; and the sealing rubber gasket is an extrusion nozzle with a short service life. After wear, residues will fall into the inside of the runner plate product, resulting in defective runner plates. Summary of the invention

[0004] The purpose of the present invention is to provide a floating sealing mechanism for a new energy flow channel plate nozzle, which has the advantages of sealing the outer side of the new energy flow channel plate nozzle to simulate the sealing of the nozzle, imitating the actual state during loading, and effectively preventing defective parts from flowing out. Moreover, since the flow channel plate nozzle body is deformed, the poor sealing caused by deformation can be effectively solved, thereby increasing efficiency.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions:

[0006] The floating plugging mechanism of the nozzle of the new energy flow channel plate comprises a plugging cylinder and a connecting block which are sequentially arranged from top to bottom, and a parallel clamping claw cylinder and a plugging head which are sequentially arranged inside the connecting block from top to bottom;

[0007] The plugging cylinder is a three-axis guide cylinder, the longitudinal vertical section of the connecting block is in the shape of a "冂", the plugging head is a cylinder with a vertical section in the shape of a "工", and the plugging head includes a limit block, a limit shaft, and a plugging block arranged in sequence from top to bottom;

[0008] The top of the connecting block is fixedly connected to the bottoms of the three telescopic rods of the plugging cylinder. The parallel jaw cylinder is fixedly located inside the connecting block. The upper end of the limiting shaft of the plugging head is located at the lower end inside the connecting block. The bottom of the connecting block is fixedly provided with two limiting plates. The two limiting plates are respectively fixedly located at the front side and the rear side of the bottom of the connecting block. The distance between the two limiting plates is 1.2 times the distance from the front side to the rear side of the jaws of the parallel jaw cylinder. A semi-circular first through hole is opened on one side of the top of each of the two limiting plates close to the limiting shaft. The upper end of the limiting shaft of the plugging head is located in the first through holes of the two limiting plates. The lower ends of the two jaws of the parallel jaw cylinder are located below the two limiting plates. The two jaws of the parallel jaw cylinder are both in contact with the lower end of the limiting shaft;

[0009] A blocking block is arranged between the limiting block of the plugging head and the parallel jaw cylinder. The blocking block is fixedly connected to the connecting block.

[0010] The preferred solutions are as follows:

[0011] Preferably: The diameter of the limiting block is 1.75 times the diameter of the limiting shaft. The diameter of the plugging block is 2.5 times the diameter of the limiting shaft. A circular slot is opened at the bottom of the plugging block. Two O-rings are fixedly embedded in the inner side wall of the circular slot from top to bottom.

[0012] Preferably: The diameter of the first through hole is 1.2 times the diameter of the limiting shaft. The limiting shaft is slidably inserted into the first through holes of the two limiting plates.

[0013] Preferably: The vertical cross-section of the circular slot at the bottom of the plugging block is in a "convex" shape. A first chamfer is provided at the step of the circular slot. A second chamfer is provided at the bottom of the circular slot. Two circular ring-shaped card slots are opened on the upper side wall of the circular slot from top to bottom. The two O-rings are both located in the card slots.

[0014] Preferably: The vertical cross-sections of the two jaws of the parallel jaw cylinder are both in an "L" shape. An arc-shaped groove is opened on one side of the lower ends of the two jaws of the parallel jaw cylinder close to the limiting shaft. The arc-shaped grooves at the lower ends of the two jaws of the parallel jaw cylinder are both in contact with the lower end of the limiting shaft.

[0015] In summary, the present invention has the following beneficial effects:

[0016] 1. Through the arrangement of the plugging cylinder and the connecting block, the plugging cylinder can push the connecting block, and then drive the plugging head to insert outside the nozzle of the new energy flow channel plate;

[0017] 2. Through the arrangement of the jaw cylinder, the plugging head can be fixed to ensure that the plugging head accurately inserts outside the nozzle of the new energy flow channel plate;

[0018] 3. Through the settings of the two jaws of the jaw cylinder, the abutting block, and the plugging head, first, the bottom of the plugging head abuts against the top of the nozzle of the new energy flow channel plate. When inserting the plugging head, the two jaws of the jaw cylinder loosen the plugging head, and the plugging head can produce a slight offset. At the same time, along with the continuous pushing of the plugging cylinder, the plugging head abuts against the abutting block, and the abutting block sleevs the plugging head outside the nozzle of the new energy flow channel plate. When the detection is completed, when the plugging cylinder pulls the plugging head outwards through the connecting block, the plugging head abuts against the two limiting plates. After being pulled out, the two jaws of the jaw cylinder clamp the plugging head again, which can prevent the plugging head from offsetting when inserted outside the nozzle of the new energy flow channel plate.

[0025] The present invention will be further described in detail below with reference to the accompanying drawings.

[0026] Among them, the same parts are denoted by the same reference numerals. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings.

[0027] The floating plugging mechanism for the nozzle of the new energy flow channel plate, as Figures 2 - 5 shown, includes a plugging cylinder 1, a connecting block 2 arranged in sequence from top to bottom, and a parallel jaw cylinder 3 and a plugging head 4 arranged in sequence from top to bottom inside the connecting block 2;

[0028] The blocking cylinder 1 is a three-axis guide cylinder, and the longitudinal vertical section of the connecting block 2 is in a "冂" shape. The top of the connecting block 2 is fixedly connected to the bottom of the three telescopic rods of the blocking cylinder 1, and the parallel clamping cylinder 3 is fixedly located inside the connecting block 2. A fourth circular through hole is opened on the left and right sides of the middle position of the front side and the rear side of the connecting block 2. A first bolt is provided in each fourth circular through hole, and each first bolt is threadedly connected to the upper end of the parallel clamping cylinder 3, thereby completing the fixation of the parallel clamping cylinder 3 and the connecting block 2.

[0029] The plugging head 4 is a cylinder with a vertical section in the shape of an "I". The plugging head 4 includes a limit block 411, a limit shaft 412, and a blocking block 413 arranged in sequence from top to bottom. The diameter of the limit block 411 is 1.75 times the diameter of the limit shaft 412, and the diameter of the blocking block 413 is 2.5 times the diameter of the limit shaft 412. The limit block 411 is plate-shaped, and the blocking block 413 is cylindrical. A circular slot is opened at the bottom of the blocking block 413, and two O-rings 414 are fixedly embedded in the inner side wall of the circular slot from top to bottom. The vertical section of the circular slot at the bottom of the blocking block 413 is "convex", and the step of the circular slot is provided A first chamfer is provided, and a second chamfer is provided at the bottom of the circular slot. Two annular grooves are provided on the upper side wall of the circular slot from top to bottom. Two O-rings 414 are both located in the grooves. Through the setting of the first chamfer and the second chamfer, when the blocking block 413 is inserted into the outer wall of the nozzle of the new energy flow channel plate, the second chamfer is first used for guidance, so that the lower end of the inner side of the blocking block 413 is first inserted into the outer wall of the nozzle of the new energy flow channel plate, and then guided by the first chamfer, the upper end of the inner side of the blocking block 413 can be conveniently inserted into the outer wall of the nozzle of the new energy flow channel plate, and then sealed by two O-rings 414.

[0030] The upper end of the limiting shaft 412 of the plugging head 4 is located at the lower end inside the connecting block 2. Two limiting plates 211 are fixedly arranged at the bottom of the connecting block 2. The two limiting plates 211 are respectively fixedly located at the front side and the rear side of the bottom of the connecting block 2. The distance between the two limiting plates 211 is 1.2 times the distance from the front side part to the rear side part of the jaws of the parallel jaw cylinder 3. On the side of the tops of the two limiting plates 211 close to the limiting shaft 412, semi-circular first through holes are opened. The upper end of the limiting shaft 412 of the plugging head 4 is located in the first through holes of the two limiting plates 211. The diameter of the first through hole is 1.2 times the diameter of the limiting shaft 412. The limiting shaft 412 is slidably inserted into the first through holes of the two limiting plates 211, which can ensure that the limiting shaft 412 can freely swing in the first through holes, and at the same time can prevent the limiting block 411 from falling out of the connecting block 2 through the first through hole. During installation, first place the limiting block 411 of the plugging head 4 at the lower end inside the connecting block 2, and then fixedly install the limiting plates 211 at the front side and the rear side of the bottom of the connecting block 2 respectively. The limiting shaft 412 of the plugging head 4 is located in the first through holes of the limiting plates 211. The two limiting plates 211 can be fixedly connected to the connecting block 2 by screws in a threaded manner.

[0031] The lower ends of the two jaws of the parallel jaw cylinder 3 are located below the two limiting plates 211. The two jaws of the parallel jaw cylinder 3 are both in contact with the lower end of the limiting shaft 412. The vertical cross-sections of the jaws of the parallel jaw cylinder 3 on the left side are all in the shape of "L". The two jaws of the parallel jaw cylinder 3 are placed symmetrically with respect to the central axis of the limiting shaft 412. Therefore, the vertical cross-sections of the two jaws of the parallel jaw cylinder 3 are both in the shape of "L". On the side of the lower ends of the two jaws of the parallel jaw cylinder 3 close to the limiting shaft 412, arc-shaped grooves are opened. The arc-shaped grooves at the lower ends of the two jaws of the parallel jaw cylinder 3 are both in contact with the lower end of the limiting shaft 412. On the front side and the rear side of the side of each arc-shaped groove close to the limiting shaft 412, chamfers are provided. Through the setting of the chamfers, it can facilitate the guiding function of the two jaws of the parallel jaw cylinder 3 when clamping.

[0032] A pressing block 5 is arranged between the limiting block 411 of the plugging head 4 and the parallel jaw cylinder 3. The pressing block 5 is fixedly connected to the connecting block 2. The distance from the left side part to the right side part of the pressing block 5 is the same as the diameter of the limiting block 411. At the upper and lower ends of the middle positions of the front side part and the rear side part of the pressing block 5, threaded holes are provided. At the lower ends of the middle positions of the front side part and the rear side part of the connecting block 2, fifth circular through holes are opened. In each fifth circular through hole, a second bolt is provided. Each second bolt is threadedly connected to its corresponding threaded hole, thereby completing the fixation of the pressing block 5. In order to facilitate the movement of the plugging head 4, a gap of 2-3 mm is left between the bottom of the pressing block 5 and the top of the plugging head 4.

[0033] However, it is impossible for this application to be in vertical lifting forever. Therefore, when it is working horizontally instead of vertically, when the plugging head 4 pulls out the nozzle of the new energy runner plate, due to the action of gravity, the plugging block 413 of the plugging head 4 will drop, causing the plugging head 4 to tilt slightly. As a result, there will be an error when the parallel jaw cylinder 3 clamps the limit shaft 412. Therefore, a number of circular grooves are circumferentially arranged at the top of the limit block 411 and the bottom of the abutment plate of the plugging head 4. A guiding post 7 is arranged in each circular groove, and a spring 6 is arranged between the two circular grooves corresponding to each other up and down. The spring 6 is sleeved on its corresponding guiding post 7. After the plugging head 4 is installed on the connecting block 2, the initial stage of each spring 6 is the compression stage. When the plugging cylinder 1 pushes the connecting block 2, each spring 6 is further compressed, so that the top of the limit block 411 abuts against the bottom of the abutment plate. When the plugging cylinder 1 drives the connecting block 2 to retreat, first the connecting block 2 retreats, and each spring 6 rebounds and abuts against the limit block 411. When the plugging head 4 exits the nozzle of the new energy runner plate, the plugging head 4 is effectively prevented from tilting slightly under the action of the rebound of a number of springs 6. Moreover, since the distance between the top of the limit block 411 and the bottom of the abutment plate is short, a number of springs 6 can be effectively prevented from being extruded out of their corresponding circular grooves.

[0034] Specific implementation process:

[0035] Step 1: The detection device drives the overall movement of the floating plugging mechanism of the new energy runner plate nozzle, so that the second chamfer at the bottom of the plugging block 413 of the plugging head 4 is located at the new energy runner plate nozzle;

[0036] Step 2: At this time, the parallel jaw cylinder 3 works, and the parallel jaw cylinder 3 drives the two jaws to translate to both sides respectively, and the two jaws of the parallel jaw cylinder 3 release the limit shaft 412 of the plugging head 4;

[0037] Step 2: The telescopic rod of the plugging cylinder 1 extends, and pushes the connecting block 2 to move towards the new energy runner plate nozzle;

[0038] Step 3: Along with the continuous extension of the telescopic rod of the plugging cylinder 1, the plugging block 413 is inserted into the outer wall of the new energy runner plate nozzle through the guiding of the second chamfer, and then through the guiding of the first chamfer, the upper end of the inner part of the plugging block 413 is inserted into the outer wall of the new energy runner plate nozzle, and then the outer wall of the new energy runner plate nozzle is sealed by two O-rings 414;

[0039] While the plugging block 413 is continuously inserted, the limit shaft 412 of the plugging head 4 slightly deflects within the first through holes of the two limit plates 211. Consequently, the limit block 411 of the plugging head 4 slightly deflects between the two limit plates 211 and the abutting block 5, and several springs 6 are compressed. If the nozzle of the new energy flow channel plate is deformed, then the top side of the limit block 411 abuts against the bottom of the abutting plate, and the plugging head 4 is pushed by the abutting block 5, thereby inserting the plugging block 413 of the plugging head 4 into the outer sidewall of the nozzle of the new energy flow channel plate;

[0040] Step Four: The detection equipment finishes the detection;

[0041] Step Five: The telescopic rod of the plugging cylinder 1 starts to contract, driving the connecting block 2 to move away from the nozzle of the new energy flow channel plate. The connecting block 2 drives the plugging block 413 to gradually disengage from the nozzle of the new energy flow channel plate. At this time, the limit block 411 of the plugging head 4 abuts against the two limit plates 211, and several springs 6 rebound and press against the limit block 411;

[0042] The plugging block 413 disengages from the nozzle of the new energy flow channel plate. Under the action of the rebounding force of the spring 6, the deflection amplitude of the plugging head 4 is small. At this time, the parallel jaw cylinder 3 operates, and the parallel jaw cylinder 3 drives the two jaws to translate towards the limit shaft 412 respectively. The arc-shaped grooves of the two jaws of the parallel jaw cylinder 3 clamp the limit shaft 412 of the plugging head 4, fixing the position of the limit shaft 412 while further correcting its position;

[0043] Step Six: The detection equipment drives the overall movement of the floating plugging mechanism of the nozzle of the new energy flow channel plate, so that the second chamfer at the bottom of the plugging block 413 of the plugging head 4 is far away from the nozzle of the new energy flow channel plate.
