Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of fixtures, in particular to a synchronous fixture. Background Art
[0002] Most of the components in a nuclear power regulating valve, such as a valve core, a valve seat, and a sleeve, are connected to each other by plasma welding. Plasma welding requires a plasma generator, which generates a high-energy arc. The high-energy arc heats the components to a temperature at which they can melt. Once the components melt, welding materials are added to the weld seam. The welding materials melt with the components, and another component adds welding materials in the same way. Then, the two components complete the plasma welding process in the plasma generator.
[0003] After the components complete the plasma welding process, they need to be immediately transferred to a heat treatment furnace for heat preservation to prevent rapid cooling. At this time, the temperature on the surface of the components will reach above 300°C. Therefore, a lifting tooling is required to assist in the transfer of the components. The existing lifting tooling hooks the components by a hook and then transfers them. However, using the hook method, problems such as shaking or even dropping of the components are likely to occur. After the component products fall, irreversible damage will be caused to the components. If the components are severely damaged, they will be directly scrapped, resulting in a large amount of waste of resources.

[0033] Such as Figures 1 to 3As shown in the figure, this embodiment provides a synchronous fixture for clamping a component 100. The synchronous fixture includes a guide member 1, a movable component 2, a connecting cylinder 3, and a clamping component 4. The guide member 1 is provided with a plurality of guide holes 11, and the plurality of guide holes 11 are arranged at intervals around the axis of the guide member 1. The movable component 2 includes a rotating member 21 and a central column 22. The rotating member 21 and the central column 22 are rotatably connected. The rotating member 21 is connected to the guide member 1, and the central column 22 is arranged perpendicular to the guide member 1. Under the action of the rotating member 21, the central column 22 can rotate relative to the guide member 1, and there will be no jamming during the rotation of the central column 22. The connecting cylinder 3 is arranged on the outer periphery of the central column 22, and the connecting cylinder 3 is threadedly connected to the central column 22. Specifically, the connecting cylinder 3 is provided with an internal thread, and the central column 22 is provided with an external thread. Thus, when the central column 22 is rotated, the connecting cylinder 3 can move relative to the central column 22, realizing the control of the connecting cylinder 3 to move up and down along the central column 22 in the height direction. The central column 22 plays a guiding role in the lifting of the connecting cylinder 3, which can ensure that the overall stability of the synchronous fixture is not affected when the connecting cylinder 3 is lifted and lowered.
[0034] The clamping component 4 is connected to the outer wall of the connecting cylinder 3. There are a plurality of clamping components 4, and the plurality of clamping components 4 are arranged at intervals. The clamping component includes a fixed seat 41, a connecting rod 42, and a clamping jaw 43. The fixed seat 41 is connected to the outer wall of the connecting cylinder 3. One end of the connecting rod 42 is rotatably connected to the fixed group, and the other end is rotatably connected to the clamping jaw 43. Thus, when the central column 22 is rotated to make the connecting cylinder 3 move up and down, the plurality of clamping jaws 43 can approach or move away from each other. That is, when the connecting cylinder 3 moves upward, the plurality of clamping jaws 43 move simultaneously and approach each other. At this time, the synchronous fixture can clamp the component 100. When the connecting cylinder 3 moves downward, the plurality of clamping jaws 43 move away from each other. At this time, the synchronous fixture releases the component 100.
[0035] Among them, the clamping jaws 43 are movably arranged in the guiding holes 11, and a plurality of clamping jaws 43 are arranged in one-to-one correspondence with a plurality of guiding holes 11. When the plurality of clamping jaws 43 approach or move away from each other, they will move along the corresponding guiding holes 11. Since the plurality of guiding holes 11 are arranged at intervals around the axis of the guiding member 1, when the plurality of clamping jaws 43 approach each other, they will approach the axis of the guiding member 1, that is, approach the same reference object, which can ensure the accuracy of the clamping position after the synchronous fixture clamps the component 100, ensure that the plurality of clamping jaws 43 are evenly distributed on the surface of the component 100, ensure that the component 100 is uniformly stressed, and prevent the component 100 from deforming during the clamping process. At the same time, the clamping jaws 43 are movably arranged in the guiding holes 11. When the synchronous fixture clamps the component 100 and rotates, the clamping jaws 43 are restricted in the guiding holes 11 and will not shake, further ensuring the stability of the two during the process of the synchronous fixture clamping the component 100 and rotating, and reducing the risk of the component 100 falling during the movement process. An anti-slip unit 431 is provided on the clamping jaws 43. The anti-slip unit 431 is arranged on the surface of the clamping jaws 43 that fits the component 100. The setting of the anti-slip unit 431 ensures the clamping force of the clamping jaws 43 on the component 100, reduces the risk of the component 100 falling during the transfer process, improves the yield rate of the component 100, and reduces the waste of resources.
[0036] For the synchronous fixture provided in this embodiment, by rotating the central column 22, the connecting cylinder 3 can be made to move up and down along the central column 22 in the height direction, and then the plurality of clamping jaws 43 approach each other, and then clamp the component 100, making the overall structure of the synchronous fixture simple and the operation convenient; by movably arranging the clamping jaws 43 in the guiding holes 11, and a plurality of clamping jaws 43 corresponding to a plurality of guiding holes 11 one by one, when the central column 22 is rotated to control the connecting cylinder 3 to move up and down, the clamping jaws 43 move along the guiding holes 11, and the plurality of clamping jaws 43 can be evenly distributed on the surface of the component 100, ensuring that the component 100 is evenly stressed during the clamping process and preventing the component 100 from deforming; at the same time, the clamping jaws 43 are movably arranged in the guiding holes 11, and the guiding holes 11 can limit the clamping jaws 43 to prevent the clamping jaws 43 from shaking and reducing the risk of the component 100 falling during the clamping process; an anti-slip unit 431 is arranged on the clamping jaws 43 to ensure the clamping force of the clamping jaws 43 on the component 100 and reduce the risk of the component 100 falling off during the transfer process.
[0037] In this embodiment, the fixed seat 41 and the outer wall of the connecting cylinder 3 are connected by bolts. Of course, the two can also be made into a snap-fit structure, and no specific limitation is made here.
[0038] In this embodiment, the rotating member 21 includes a bearing 211, wherein the bearing 211 is connected to the guide member 1, and the center column 22 is connected to the inner ring of the bearing 211, so that when the staff rotates the center column 22, so that the multiple clamps 43 clamp the parts 100 or put down the parts 100, the center column 22 will not be stuck, thereby improving the convenience of the staff's operation. Exemplarily, a middle hole is provided at the center position of the guide member 1, the bearing 211 is assembled in the middle hole, and the center column 22 is penetrated in the inner ring. Preferably, the rotating member 21 also includes a retaining ring 212, which is clamped on the outer periphery of the center column 22, and the end face of the retaining ring 212 is in contact with the end face of the inner ring of the bearing 211. The setting of the retaining ring 212 can prevent the inner ring of the bearing 211 from moving up and down when the staff rotates the center column 22 and drives the inner ring of the bearing 211 to rotate, and further ensures the stability of the bearing 211 when the center column 22 rotates and drives the bearing 211 to rotate. In this embodiment, the retaining ring 212 is fixed to the outer circumference of the central column 22 by means of locking bolts.
[0039] In this embodiment, the synchronous clamp further includes a protruding piece 5, which is arranged at one end of the central column 22 away from the guide column. The arrangement of the protruding piece 5 enables the staff to rotate the central column 22 more effortlessly. There are four protruding pieces 5, and the four protruding pieces 5 are spaced around the outer circumference of the central column 22, which makes it easier for the staff to operate. The protruding piece 5 and the central column 22 can be set as an integral structure or a split structure, which is not specifically limited here.
[0040] For example, regarding the rotational connection between the fixed seat 41 and the connecting rod 42, the clamping assembly 4 also includes a first pin 44 and a second pin 45, wherein the fixed seat 41 has a first mounting groove 411. During assembly, one end of the connecting rod 42 is inserted into the first mounting groove 411. At the same time, mounting holes are provided on both side walls of the connecting rod 42 and the first mounting groove 411. The staff member sequentially passes the first pin 44 through the corresponding mounting holes of the two. At this time, the first pin 44 penetrates and connects the fixed seat 41 and the connecting rod 42, so that the connecting rod 42 and the fixed seat 41 can be rotationally connected. On the other hand, it is also possible to set a protrusion on the fixed seat 41, set the first mounting groove 411 on the connecting rod 42, insert the protrusion of the fixed seat 41 into the first mounting groove 411 on the connecting rod 42 during installation, and pass the first pin 44 through the fixed seat 41 and the connecting rod 42, so that the connecting rod 42 and the fixed seat 41 can also be rotationally connected.
[0041] Exemplarily, regarding the rotational connection between the connecting rod 42 and the jaw 43, the jaw 43 has a second mounting groove 432. During assembly, the other end of the connecting rod 42 is inserted into the second mounting groove 432. At the same time, mounting holes are provided on two side walls of the connecting rod 42 and the second mounting groove 432. The staff sequentially passes the second pin shaft 45 through the corresponding mounting holes of the two. At this time, the second pin shaft 45 penetrates and connects the jaw 43 and the connecting rod, enabling a rotational connection between the jaw 43 and the connecting rod. On the other hand, it is also possible to choose to provide a protruding portion on the jaw 43 and a second mounting groove 432 on the connecting rod 42. During assembly, the protruding portion of the jaw 43 is inserted into the second mounting groove 432 of the connecting rod 42, and the second pin shaft 45 penetrates the jaw 43 and the connecting rod 42, which can also achieve the rotational connection between the connecting rod 42 and the jaw 43.
[0042] In this embodiment, the surface of the jaw 43 that fits the component 100 has anti-slip threads, and the anti-slip threads are the anti-slip unit 431.
[0043] In this embodiment, the guiding member 1 is a column with a circular cross-section. In this way, when the synchronous fixture clamps and transports the component 100, it can avoid the problem of uneven force on the synchronous fixture caused by the guiding member 1, and further improve the stability of the entire fixture when clamping the component 100. Of course, making the guiding member 1 into a column with a circular cross-section is only a preferred result. The guiding member 1 can also be made into a column with a triangular cross-section, a column with a quadrilateral cross-section, or a column with a hexagonal cross-section, which is not specifically limited here.
[0044] In this embodiment, the synchronous fixture further includes a hanging ring 6. The hanging ring 6 is connected to the end of the central column 22 away from the guiding member 1. The setting of the hanging ring 6 facilitates the storage of the synchronous fixture and improves the rationality of the design of the synchronous fixture.
[0045] In this embodiment, six clamping assemblies 4 are provided, and the six clamping assemblies 4 are arranged at intervals around the outer wall of the connecting cylinder 3. In this way, when the synchronous fixture clamps the component 100, it can clamp the component 100 from six contact points of the component 100, further ensuring the stability of the synchronous fixture when clamping the component 100. Of course, the number of clamping assemblies 4 can also be set to eight or ten, and the number of the clamping assemblies 4 is not specifically limited here.
[0046] Obviously, the above embodiments of the present invention are merely examples for clearly explaining the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments, and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the claims of the present invention.
