[0024] It should be pointed out that the terms "first", "second" and the like in the specification and claims of the utility model and the above-mentioned drawings are used to distinguish similar objects, and do not have to be used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the utility model described herein can be implemented in an order other than those illustrated or described herein.

[0025] In combination with Figures 1 to 3 As shown in the drawings, the utility model embodiment provides a kind of filling tensioning clamp, including mounting seat 1, liquid plastic 2, bushing 3 and cock 4, one end of mounting seat 1 axially is used to be connected with chuck 5, bushing 3 is sleeved in the end of mounting seat 1 away from chuck 5, the outer peripheral wall of bushing 3 is used to be closely connected with the inner wall of processing part 6, mounting seat 1 includes the main cavity 11 and multiple vice cavities 12 around main cavity 11 along its axial direction, multiple vice cavities 12 are communicated between bushing 3 and main cavity 11, main cavity 11 penetrates mounting seat 1, liquid plastic 2 is filled in main cavity 11 and multiple vice cavities 12, one end of main cavity 11 axially is blocked, cock 4 is threadedly connected with the other end of main cavity 11 axially, the screwing of cock 4 is used to extrude liquid plastic 2, so that bushing 3 is radially expanded;Vice cavity 12 is communicated with the part of main cavity 11 close to the blocked end of main cavity 11.

[0026] Specifically, the mounting seat 1 is a columnar structure, and its axis is parallel to the X-axis direction. The mounting seat 1 is located at one end of the X-axis negative direction for detachable connection with the chuck 5, and the mounting seat 1 is located at one end of the X-axis positive direction towards the machined part 6. The main cavity 11 extends along the axis of the mounting seat 1, and a plurality of auxiliary cavities 12 surround the main cavity 11 and communicate with the main cavity 11. Each auxiliary cavity 12 extends to the outer peripheral wall of the mounting seat 1 at an end away from the main cavity 11. The sleeve 3 is sleeved on one end of the mounting seat 1 located at the X-axis positive direction, and the inner wall of the sleeve 3 is in seamless contact with the outer peripheral wall of the mounting seat 1. Specifically, the mounting seat 1 is cooled by liquid nitrogen, and then the sleeve 3 is sleeved on the mounting seat 1. After the temperature of the mounting seat 1 returns to normal, the inner wall of the sleeve 3 is in seamless contact (interference fit) with the outer peripheral wall of the mounting seat 1. The machined part 6 is sleeved on the sleeve 3. Here, the machined part 6 specifically refers to a pipe structure with a relatively short axial length and an axial through hole. The liquid plastic 2 is filled in the main cavity 11 and the plurality of auxiliary cavities 12. Since the main cavity 11 is blocked at one end of the X-axis negative direction, the plurality of auxiliary cavities 12 communicate with the main cavity 11 at a position close to the blocked end of the main cavity 11. It can be understood that the communication part of the plurality of auxiliary cavities 12 with the main cavity 11 is concentrated at the position of the main cavity 11 close to the blocked end of the main cavity 11, that is, the left end of the main cavity 11, so that the position where the plurality of auxiliary cavities 12 communicate with the main cavity 11 is as far away from the tap 4 as possible to increase the rotation length of the tap 4 and improve the extrusion effect of the tap 4 on the liquid plastic 2. Specifically, if the position where the plurality of auxiliary cavities 12 communicate with the main cavity 11 is relatively close to the tap 4, the tap 4 will extrude the liquid plastic 2 after rotating a small distance, and the liquid plastic 2 will be subjected to a small pressure. If the position where the plurality of auxiliary cavities 12 communicate with the main cavity 11 is relatively far away from the tap 4, the tap 4 will rotate a longer distance, which can have a greater extrusion effect on the liquid plastic 2, that is, the longer the rotation length of the tap 4, the better the extrusion effect on the liquid plastic 2. After the tap 4 is threadedly connected to one end of the main cavity 11 located at the X-axis positive direction, the main cavity 11 and the plurality of auxiliary cavities 12 are sealed by the tap 4 and the sleeve 3. A tool extends into the machined part 6 from the hollow of the machined part 6 and drives the tap 4 to be tightened. The tap 4 moves into the main cavity 11 along the axis of the main cavity 11, and the liquid plastic 2 is gradually extruded and the pressure increases. The extruded liquid plastic 2 applies uniform pressure to the sleeve 3 through the plurality of auxiliary cavities 12. Under the action of the pressure, the sleeve 3 is slightly radially expanded to tighten the machined part 6 from the inside of the machined part 6, so as to clamp the machined part 6 and ensure that the machined part is balanced in force to avoid deformation before and after clamping.

[0027] Therefore, in the embodiment, the main cavity 11 extends along the axial direction of the mounting base 1, the plurality of auxiliary cavities 12 surround the main cavity 11 and are in communication with the main cavity 11, the auxiliary cavities 12 are in communication with the part of the main cavity 11 close to the blocking end of the main cavity 11, the liquid plastic 2 filled in the main cavity 11 and the plurality of auxiliary cavities 12 can be uniformly distributed in the mounting base 1, the sleeve 3 is sleeved on the end of the mounting base 1 away from the chuck 5, the plurality of auxiliary cavities 12 are in communication between the sleeve 3 and the main cavity 11, the sleeve 3 blocks the plurality of auxiliary cavities 12, and after the plug 4 is threadedly connected to the other end of the main cavity 11 in the axial direction, the main cavity 11 and the plurality of auxiliary cavities 12 form a closed cavity, the one end of the mounting base 1 in the axial direction is used to be connected to the chuck 5, the outer circumferential wall of the sleeve 3 is used to be tightly connected to the inner wall of the machining part 6, the sleeve 3 is positioned on the machining part 6 under the support of the mounting base 1, the plug 4 is screwed and extrudes the liquid plastic 2, the liquid plastic 2 is extruded to the sleeve 3 under the guidance of the plurality of auxiliary cavities 12, and the sleeve 3 is radially expanded after the liquid plastic 2 is extruded, the expanded sleeve 3 is tightly expanded on the machining part 6 from the inside of the machining part 6, the machining part 6 is guaranteed to be in force balance, deformation of the machining part 6 before and after clamping is avoided, clamping of the small-size and thin-wall pipe part is realized, and the machining quality of the small-size and thin-wall pipe part is guaranteed.

[0028] Optionally, in combination with the Figure 2 and Figure 3 shown, the filling and expanding clamp further comprises a limiting sleeve 7, the limiting sleeve 7 is sleeved on the sleeve 3, one end of the limiting sleeve 7 in the axial direction is detachably connected to the mounting base 1, and the other end of the limiting sleeve 7 in the axial direction is used to abut against the machining part 6.

[0029] Specifically, the limiting sleeve 7 is sleeved on the sleeve 3, and the axial dimension of the limiting sleeve 7 is smaller than the axial dimension of the sleeve 3. One end of the limiting sleeve 7 in the axial direction is detachably connected to the mounting base 1, and the other end of the limiting sleeve 7 in the axial direction is connected to the end of the machining part 6. The limiting sleeve 7 compensates the area covered by the machining part 6 and the sleeve 3 in the axial direction. For example, the machining part 6 can have multiple models with different lengths, and the limiting sleeve 7 can also have multiple models with different lengths. If the machining part 6 is sleeved on the sleeve 3, the inner wall of the machining part 6 cannot completely cover the sleeve 3. Therefore, the limiting sleeve 7 of the corresponding model is sleeved on the sleeve 3 before the machining part 6 is sleeved on the sleeve 3. The connection between the limiting sleeve 7 and the machining part 6 realizes complete coverage of the sleeve 3. When the plug 4 is screwed, the limiting sleeve 7 limits the sleeve 3 in the radial direction to ensure the uniformity of the axial micro-deformation of the sleeve 3.

[0030] In this way, the limiting sleeve 7 is sleeved on the sleeve 3, one end of the limiting sleeve 7 in the axial direction is detachably connected to the mounting base 1, and the other end of the limiting sleeve 7 in the axial direction is used to abut against the machining part 6. The limiting sleeve 7 can completely cover the sleeve 3 with the machining part 6. After the plug 4 is screwed, the limiting sleeve 7 limits the sleeve 3 in the radial direction to ensure the uniformity of the axial micro-deformation of the sleeve 3, thereby improving the use flexibility of the sleeve 3.

[0031] Optionally, in combination with Figure 2 and Figure 3 As shown in the figure, the filling and tensioning fixture further comprises a limiting pin 8, which penetrates the bushing 3 along the radial direction of the bushing 3 and is inserted into the mounting seat 1.

[0032] Specifically, the mounting seat 1 is provided with a slot extending along the radial direction thereof, and the bushing 3 is provided with a through hole extending along the radial direction of the bushing 3 at a position corresponding to the slot, the limiting pin 8 is embedded in the through hole and inserted into the slot, the limiting pin 8 axially limits the bushing 3, and when the bushing 3 is radially expanded, the axial displacement of the bushing 3 is avoided.

[0033] In this way, by penetrating the bushing 3 along the radial direction of the bushing 3 and being inserted into the mounting seat 1, the limiting pin 8 realizes the axial displacement of the bushing 3, ensures that the bushing 3 only slightly deforms along the radial direction thereof, and ensures the stability of the bushing 3.

[0034] Optionally, in combination with Figure 1 As shown in the figure, the mounting seat 1 further comprises an injection hole 14, which is located at one end of the main cavity 11 away from the cock 4 and communicates with the main cavity 11, and a detachable plugging screw is further arranged in the injection hole 14.

[0035] Specifically, the injection hole 14 is located at one end of the main cavity 11 away from the cock 4, that is, the main cavity 11 is located at one end of the X-axis in the negative direction, and the injection hole 14 communicates with the main cavity 11. Before filling the liquid plastic 2, the detachable plugging screw is removed from the injection hole 14, and then the liquid plastic 2 is filled. During the filling process, the cock 4 is stationary, and after the filling is completed, the detachable plugging screw is tightened.

[0036] In this way, by locating the injection hole 14 at one end of the main cavity 11 away from the cock 4 and communicating with the main cavity 11, and further arranging a detachable plugging screw in the injection hole 14, the liquid plastic 2 can be filled from one end of the main cavity 11 away from the cock 4, and the liquid plastic 2 is extruded from the cock 4 at the other end of the main cavity 11, so that after the mounting seat 1 is connected with the chuck 5, the detachable plugging screw is avoided from being exposed, so as to reduce the risk of the detachable plugging screw being touched by the machining tool during the machining process of the workpiece 6, and further ensure the sealing effect of the main cavity 11.

[0037] Optionally, in combination with Figure 1 As shown in the figure, the sealing end of the main cavity 11 is provided with a detachable plug 13, and the detachable plug 13 is threadedly connected with the main cavity 11.

[0038] Specifically, the blocked end of the main cavity 11 is the end of the main cavity 11 located on the negative direction of the X axis. During the filling process, the detachable plug 13 can be removed to facilitate the observation of the filling of the liquid plastic 2, avoid waste caused by excessive filling of the liquid plastic 2, and play an observation role to ensure that the liquid plastic 2 is filled appropriately. After the liquid plastic 2 is filled appropriately, the main cavity 11 is sealed by the detachable plug 13.

[0039] Optionally, in combination with Figure 2 As shown, the inner circumferential wall of the bushing 3 is provided with a containing groove 31, and the containing groove 31 is in communication with the plurality of secondary cavities 12.

[0040] Specifically, the containing groove 31 can be an annular groove around the axis of the bushing 3, or a groove in one-to-one correspondence with the secondary cavities 12. When the liquid plastic 2 is extruded, the liquid plastic 2 can flow into the containing groove 31, so that the contact area between the liquid plastic 2 and the bushing 3 increases. In this way, the effect of expanding the bushing 3 by the liquid plastic 2 can be improved.

[0041] Optionally, in combination with Figure 1 As shown, the positions where the plurality of secondary cavities 12 are in communication with the main cavity 11 are located at the same part of the main cavity 11 close to the blocked end thereof.

[0042] Specifically, the positions where the plurality of secondary cavities 12 are in communication with the main cavity 11 are concentratedly distributed at the same part of the main cavity 11 close to the blocked end thereof, that is, the positions where the plurality of secondary cavities 12 are in communication with the main cavity 11 are concentratedly located on the left side of the main cavity 11. When the plug 4 is screwed, the liquid plastic 2 is concentratedly flowed from the end of the main cavity 11 away from the plug 4 into the plurality of secondary cavities 12, so as to ensure the expansion effect of the liquid plastic 2 on the bushing 3. Exemplarily, if the communication positions of the secondary cavities 12 and the main cavity 11 are not concentrated, the amount of the liquid plastic 2 in each secondary cavity 12 can be inconsistent, which can result in the situation that the bushing 3 cannot be uniformly expanded.

[0043] Optionally, in combination with Figure 1 As shown, the filling and expanding clamp further comprises a pressure sensor and a display device wirelessly connected with the pressure sensor, and the pressure sensor is embedded in the inner wall of the secondary cavity 12. The display device is used to display the detection value of the pressure sensor.

[0044] Specifically, the pressure sensor is embedded in the inner wall of a single or multiple secondary cavities 12, and the contact of the pressure sensor faces the inside of the secondary cavity 12. When the liquid plastic 2 is extruded, the pressure sensor can detect the pressure of the liquid plastic 2 and display the pressure through the display device. In the subsequent machining process of the workpiece 6, the extrusion effect of the plug 4 on the liquid plastic 2 can be fed back through the value displayed by the display device, that is, if the value displayed by the display device becomes smaller, it means that the plug 4 needs to be tightened to ensure the expansion effect of the bushing 3. In this way, the expansion and clamping of the bushing 3 on the workpiece 6 can be fed back, so as to ensure the machining stability of the workpiece 6.

[0045] The utility model discloses another embodiment still provides a machine tool, including chuck 5 and as described in the preceding filling tension fixture, and the mounting seat 1 of chuck 5 is connected with the filling tension fixture.

[0046] Specifically, after the processing part 6 is sleeved on the bushing 3 of the filling tension fixture, the end of the mounting seat 1 of the filling tension fixture away from the processing part 6 is connected with the chuck 5 through the threaded fastener, to support the mounting seat 1, and ensure the stability of the mounting seat 1. Then, the liquid plastic 2 is extruded by the screwing of the plug 4 of the filling tension fixture, and the radial micro-expansion of the bushing 3 is realized through the liquid plastic 2, so as to ensure that the processing part 6 is uniformly stressed, and further ensure the processing quality of the subsequent processing part 6.

[0048] The utility model discloses another embodiment still provides a processing system, including the machine tool as described in the preceding.
