Description
Technical Field
[0001] The utility model relates to the technical field of component processing, in particular to a blocking device. Background Art

The empty spring hole itself is a blind hole, but because the hole wall of the empty spring hole is provided with air holes connected to the additional air chamber (the air holes are prefabricated before machining the empty spring hole), once the cutting fluid and the iron pin enter the additional air chamber through the air holes on the hole wall of the empty spring hole, it will be extremely difficult to clean. Therefore, it is very important to seal the air holes on the inner wall of the empty spring hole. In the current machining process, the rod-shaped metal material is usually The plugging device is directly inserted into the plugging tube, so that the side of the rod-shaped plugging device directly blocks the pores. However, since metal materials are hard and not easy to deform (plugging devices made of wood or rubber cannot withstand high temperatures), when manufacturing these plugging devices, it is necessary to make the cross-sectional dimensions of the plugging device slightly smaller than the cross-sectional dimensions of the empty spring hole. For example, the cross-sectional shapes of the empty spring hole and the plugging device are both circular, the diameter of the empty spring hole is 40mm, and the diameter of the plugging device is 39.5mm. This will cause a gap between the plugging device and the side wall of the empty spring hole when it is inserted into the empty spring hole, and the sealing effect on the pores in the empty spring hole is poor. Therefore, there is an urgent need for a plugging device that can improve the sealing performance of the pores in the empty spring hole during the processing. Utility Model Content

DETAILED DESCRIPTION

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] The utility model aims to provide a blocking device to solve the problems existing in the prior art and to improve the sealing performance when blocking the air holes in the empty spring holes during the processing.
[0023] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0024] Embodiment 1
[0025] This embodiment provides a blocking device, such as Figure 1-4 As shown, it includes: a sealing seat 1 made of high-temperature resistant material, a sealing tube 2 and a supporting structure. A part of the end surface of one end of the sealing tube 2 is fixedly connected to one side of the sealing seat 1. The sealing seat 1 is used to be set in the empty spring hole. At least a part of the sealing tube 2 is used to be set in the empty spring hole. The supporting structure can support the sealing tube 2 so that the sealing tube 2 is deformed and contacts the inner wall of the empty spring hole.
[0026] The plugging device provided in this embodiment, the plugging seat 1, the plugging tube 2 and the supporting structure made of high temperature resistant materials can withstand the high temperature of the iron pin in a relatively high temperature state. By setting the plugging seat 1 and at least a part of the plugging tube 2 in the empty spring hole (the plugging tube 2 can be completely placed in the empty spring hole, or a part close to the plugging seat 1 can be placed in the empty spring hole), and using the supporting structure to support the plugging tube 2, and deforming the plugging tube 2, the plugging tube 2 can contact the inner wall of the empty spring hole. At this time, the side of the plugging tube 2 can block the pores on the side of the empty spring hole, thereby improving the sealing performance when the pores in the empty spring hole are blocked during the processing, and the cutting fluid and iron pins generated during the processing of the frame will not enter the air chamber through the empty spring hole. Among them, the cross-sectional shape of the plugging tube 2 is preferably circular, the outer diameter of the plugging tube 2 is smaller than the aperture of the empty spring hole, and the difference between the outer diameter of the plugging tube 2 and the aperture of the empty spring hole is 0.4mm-0.6mm.
[0027] In a preferred implementation of the present embodiment, the blocking seat 1, the blocking tube 2 and the supporting structure are all made of high-temperature resistant metal materials. An expansion channel 3 is provided on the wall surface of the blocking tube 2, which passes through both ends of the blocking tube 2. A portion of the end surface of one end of the blocking tube 2 is fixedly connected to one side of the blocking seat 1. When the supporting structure supports the empty spring hole, the distance between the two inner sides of the expansion channel 3 increases, and the blocking tube 2 deforms and contacts the inner wall of the empty spring hole to achieve the blocking of the empty spring hole. In the process of using soft materials to block the empty spring hole, a large degree of wear will occur after long-term use, and it cannot be reused for a long time. The use of metal materials makes the blocking device have good deformation ability and wear resistance, which can meet the needs of long-term repeated use. Among them, during use, in order to avoid the influence of the expansion channel 3 on the blocked pores, it is necessary to pre-set the expansion channel 3 and the pores in a staggered manner so that the side of the blocking tube 2 can contact and block the pores in the empty spring hole.
[0028] It should be noted that the sealing device provided by the utility model can adopt a variety of forms of the top support structure according to the different materials of the sealing tube 2. When the sealing tube 2 is made of elastic high-temperature resistant material, the top support structure can be set to be in the shape of a table, and the size of the small end of the table is the same as the size of the tube mouth of the sealing tube 2 when it is not deformed. As the table moves into the sealing tube 2, the large end gradually approaches the sealing tube 2, so that the sealing tube 2 is deformed to contact the inner wall of the empty spring hole; when the sealing tube 2 is a rigid structure, a telescopic rod can be arranged inside the sealing tube 2, and the two ends of the telescopic rod are against the inner side surface of the sealing tube 2. The sealing tube 2 is deformed to contact the inner wall of the empty spring hole through the extension and retraction of the telescopic rod.
[0029] In a preferred implementation of this embodiment, the supporting structure includes a slider 4, at least a portion of which is slidably connected in the expansion channel 3, and the slider 4 has at least one contact point with each inner wall of the expansion channel 3, and the slider 4 can slide along the expansion channel 3 and squeeze the inner side wall of the expansion channel 3 to increase the distance between the inner side walls of the expansion channel 3. The slider 4 can slide along the expansion channel 3 to squeeze the expansion channel 3, and the distance between the inner side walls of the expansion channel 3 increases, and the blocking tube 2 is deformed as a whole, and the outer side surface of the blocking tube 2 can move and contact the inner side wall of the empty spring hole, thereby achieving the blocking of the air hole. Among them, the shapes of the expansion channel 3 and the slider 4 can be set as needed. For example, the two inner side walls of the expansion channel 3 can be set as two inclined planes, and the distance between the two inclined planes gradually decreases from one end of the expansion channel 3 to the other end. The two side surfaces of the slider 4 used to contact the expansion channel 3 are parallel to each other. During the process of the slider 4 sliding from the large end to the small end of the expansion channel 3, the slider 4 can support the expansion channel 3 to deform the blocking tube 2; the two side surfaces of the slider 4 used to contact the expansion channel 3 can also be set as inclined planes, and the distance between the two inclined planes gradually decreases in the direction of the line connecting one end to the other end of the expansion channel 3. The two inner side walls of the expansion channel 3 are parallel to each other, and the small end of the slider 4 enters the expansion channel 3 first. During the process of the large end of the slider 4 gradually approaching the expansion channel 3, the slider 4 can squeeze the expansion channel 3 and gradually increase the distance between the two side surfaces of the expansion channel 3, thereby causing the blocking tube 2 to deform.
[0030] In a preferred implementation manner of the present embodiment, one end of the expansion channel 3 away from the blocking seat 1 is the first end 31, and the other end is the second end 32. A portion of the expansion channel 3 close to the first end 31 is the first expansion channel, and a portion close to the second end 32 is the third expansion channel. The second expansion channel is between the first expansion channel and the third expansion channel. The two sides of the slider 4 used to contact the expansion channel 3 are both outer sides. Among the outer sides, the outer sides close to the first end 31 are the first outer sides 41, and the outer sides close to the second end 32 are the second outer sides 42. The sides of the first expansion channel, the second expansion channel, and the third expansion channel used to contact the slider 4 are the first inner side 33, the second inner side 42, respectively. side surface 34 and the third inner side surface 35; the distance between the two second outer side surfaces 42 and the distance between the two second inner side surfaces 34 gradually decrease from the direction of the line connecting the first end 31 to the second end 32; the two ends of the two first inner side surfaces 33 away from the first end 31 are respectively connected with the two ends of the two second inner side surfaces 34 close to the first end 31, and the two first inner side surfaces 33 are parallel to each other, and the two ends of the two third inner side surfaces 35 away from the second end 32 are respectively connected with the two ends of the two second inner side surfaces 34 close to the second end 32, and the two third inner side surfaces 35 are parallel to each other; the distance between the two first outer side surfaces 41 is equal to the distance between the two first inner side surfaces 33. When the blocking tube 2 is not deformed, the first inner side surface 33 of the slider 4 contacts the second outer side surface 42 of the expansion channel 3, and the second inner side surface 34 contacts the second outer side surface 42, so that the slider 4 can be stably set in the expansion channel 3; when the blocking tube 2 needs to be deformed, the slider 4 is moved toward the blocking seat 1. At this time, the first inner side surface 33 contacts and squeezes the second outer side surface 42, and the second inner side surface 34 contacts and squeezes the third outer side surface. The distance between the inner side walls of the expansion channel 3 gradually increases, and the blocking tube 2 can also be deformed. This cooperation mode between the expansion channel 3 and the slider 4 can enable the slider 4 to better block the expansion channel 3, thereby preventing liquid from leaking from the expansion channel 3 and enhancing the blocking effect.
[0031] In a preferred implementation of this embodiment, the supporting structure further includes a guide rod 5, which extends in the direction in which the expansion channel 3 extends, and is movably connected to the blocking seat 1. The slider 4 is sleeved outside the guide rod 5, and the guide rod 5 can move in the direction in which the expansion channel 3 extends and drive the slider 4 to move toward the second end 32. The guide rod 5 can fix the slider 4 to prevent the slider 4 from detaching from the expansion channel 3, thereby increasing the reliability of the device.
[0032] In a preferred implementation of this embodiment, the guide rod 5 is a screw rod, which is threadedly connected to the blocking seat 1. A nut 51 is fixedly provided at the end of the screw rod near the first end 31, and a fixing ring 43 is fixedly sleeved on the screw rod. The slider 4 is sleeved on the screw rod between the fixing ring 43 and the nut 51. The screw rod can rotate relative to the slider 4, and the two sides of the slider 4 are in contact with the nut 51 and the fixing ring 43 respectively. When it is necessary to block the empty spring hole, a tool such as a wrench is used to rotate the screw rod from the nut 51 so that the screw rod is gradually screwed into the blocking seat 1. During the rotation of the screw rod, the nut 51 can press and drive the slider 4 to move in the direction close to the blocking seat 1, and the fixing ring 43 can prevent the slider 4 from falling off. This adjustment method can convert the rotation of the screw rod into the linear movement of the slider 4, making the operation easier.
[0033] In a preferred implementation of this embodiment, a portion of the circumferential edge on one end of the blocking tube 2 extends in the direction of the blocking seat 1 and forms a connecting portion 21, and the blocking tube 2 is fixedly connected to the blocking seat 1 through the connecting portion 21. The connecting portion 21 can make the blocking tube 2 firmly connected to the blocking seat 1, and at the same time, the blocking seat 1 and the blocking tube 2 are only connected by the smaller connecting portion 21, and the blocking tube 2 itself can be deformed. Among them, the connecting portion 21 is arranged opposite to the expansion channel 3; the blocking seat 1 also has a protrusion at a position corresponding to the expansion channel 3, and the protrusion extends from the circumferential edge of the blocking seat 1 in the direction of the expansion channel 3, and the end of the protrusion away from the blocking seat 1 contacts a portion of the blocking tube 2 close to the end of the blocking seat 1, and the protrusion can support the blocking tube 2.
[0034] In a preferred implementation manner of this embodiment, the blocking tube 2 and the blocking seat 1 are both made of steel.
[0035] Embodiment 2
[0036] The plugging device provided by the utility model can also be used for plugging holes in liquid pipelines. It only needs to open a through hole connecting the two sides of the plugging seat 1 on the surface of the plugging seat 1. When the side of the liquid pipeline is damaged, the plugging device is inserted into the pipeline so that the side of the plugging tube 2 corresponds to the damaged position of the pipeline. The supporting device is used to support the plugging tube 2 so that the side of the plugging tube 2 contacts the inner wall of the pipeline and blocks the damaged position. The liquid can also flow through the pipeline through the through hole at the bottom of the plugging seat 1.

The above examples are only used to help understand the method and core idea of the present invention.
