Description

Technical Field

[0001] The utility model relates to the technical field of graphite crucible processing, and specifically relates to a graphite crucible processing tooling fixture. Background Art

[0002] When processing a graphite crucible, in order to ensure that the graphite crucible can remain stable during the processing, a processing tooling fixture can be used to conveniently and quickly clamp and fix the graphite crucible, so that the graphite crucible can maintain the correct position and posture during the processing, thereby avoiding processing errors and ensuring processing quality. At the same time, according to the shape, the existing graphite crucibles are mainly divided into two types: square and cylindrical.

[0003] When the existing processing tooling fixture clamps and fixes the graphite crucible, it is mainly achieved through the cooperation of a fixed clamping member and a movable clamping member. However, considering that different-shaped graphite crucibles need to be adapted to different clamping members for processing, the existing processing tooling fixture will have problems of inappropriate clamping and fixing and poor versatility in the actual processing process. Therefore, a graphite crucible processing tooling fixture is proposed for the above problems. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a graphite crucible processing tooling fixture to solve the problems of inappropriate processing and non-universality existing in the existing processing tooling fixture when clamping and fixing the graphite crucible due to the different shapes of the graphite crucibles as mentioned in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A graphite crucible processing tooling fixture includes a base. One side of the top of the base is fixedly connected with a fixed clamping plate. An activity slot is opened on one side surface of the fixed clamping plate close to the middle position of the base. A rotating member is arranged inside the activity slot. An auxiliary clamping plate is fixedly connected to the rear of the rotating member. A rotating shaft is inserted into the top of the rotating member. A gear ring is sleeved outside the rotating shaft. A rack is meshed and connected to the outside of the gear ring. One end of the rack is fixedly connected with a push block. A first telescopic rod is arranged behind the push block. The first telescopic rod is fixedly installed inside the activity slot.

[0007] Preferably, a limiting vertical plate is fixedly connected to the other side of the top of the base. A second telescopic rod is horizontally arranged through one side position of the limiting vertical plate close to the middle position of the base. The movable end of the second telescopic rod is fixedly connected with an adapter block. A group of the second telescopic rods is arranged above the base.

[0008] Preferably, a movable clamping plate is fixedly connected to one side position of the adapter block away from the second telescopic rod. The movable clamping plate and the fixed clamping plate are arranged with their clamping surfaces facing each other.

[0009] Preferably, a group of the rotating members are arranged in a front-back symmetric structure along the center point of the movable slot, and the rotating shaft is rotatably connected through the movable slot and the fixed clamping plate.

[0010] Preferably, every two of the first telescopic rods are provided as a group, and a total of two groups are provided. A group of the first telescopic rods and a group of racks arranged inside the movable slot are arranged in a vertically staggered manner. Every two of the auxiliary clamping plates are provided as a group, and a total of two groups are provided. The connection between the rack and the push block forms an "L"-shaped structure. The height of the rotating member is less than the height of the auxiliary clamping plate.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] In the present utility model, through the arranged fixed clamping plate, movable slot, rotating member, auxiliary clamping plate, rotating shaft, toothed ring, rack, push block, first telescopic rod and movable clamping plate, it is convenient for the graphite crucible processing tooling to adapt and adjust the clamping structure composed of the fixed clamping plate, movable slot, rotating member, auxiliary clamping plate, rotating shaft, toothed ring, rack, push block, first telescopic rod and movable clamping plate according to the specific shape of the graphite crucible when actually carrying out the clamping and fixing operation, so that the entire tooling equipment can adapt to clamp and fix graphite crucibles of different shapes after being adjusted to the corresponding working mode. And this structural design can effectively improve the versatility and practicability of the entire tooling equipment during actual work, and at the same time, it can also reduce the limitation brought by the inconsistent shape of the graphite crucible to the work of the entire tooling equipment.

Detailed Embodiment

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

[0019] Please refer to Figures 1-4 , the present utility model provides a technical solution:

[0020] A graphite crucible processing tooling, including a base 1, a fixed clamping plate 2 is fixedly connected to one side of the top of the base 1, an activity slot 3 is opened on one side surface of the fixed clamping plate 2 close to the middle position of the base 1, a rotating member 4 is arranged inside the activity slot 3, an auxiliary clamping plate 5 is fixedly connected to the rear of the rotating member 4, a rotating shaft 6 is inserted into the top of the rotating member 4, a toothed ring 7 is sleeved outside the rotating shaft 6, a rack 8 is meshed and connected to the outside of the toothed ring 7, a push block 9 is fixedly connected to one end of the rack 8, and a first telescopic rod 10 is arranged behind the push block 9. The first telescopic rod 10 is fixedly installed inside the activity slot 3.

[0021] As Figure 1 shown, a limiting vertical plate 11 is fixedly connected to the other side of the top of the base 1, a second telescopic rod 13 is horizontally arranged through one side position of the limiting vertical plate 11 close to the middle position of the base 1, and a connecting block 12 is fixedly connected to the moving end of the second telescopic rod 13. A group of second telescopic rods 13 are arranged above the base 1. When a group of second telescopic rods 13 perform a horizontal movement operation, a group of limiting vertical plates 11 will play an auxiliary supporting role; a movable clamping plate 14 is fixedly connected to one side position of the connecting block 12 away from the second telescopic rod 13. The clamping surfaces of the movable clamping plate 14 and the fixed clamping plate 2 are arranged opposite to each other. Since the movable clamping plate 14 and the fixed clamping plate 2 components are arranged opposite to each other, after the graphite crucible is placed in place, this setting will facilitate the entire tooling device to complete the entire clamping and fixing operation by making the movable clamping plate 14 and the fixed clamping plate 2 move relative to each other.

[0022] As Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a set of rotating members 4 are arranged in a front-back symmetric structure along the center point of the movable slot 3. The rotating shaft 6 is rotatably connected to the fixed clamping plate 2 through the movable slot 3. The rotating member 4 is rotatably connected to the fixed clamping plate 2 or the movable clamping plate 14 through the rotating shaft 6, which is beneficial for the auxiliary clamping plate 5 to be quickly unfolded by means of flipping rotation; There are two sets of the first telescopic rods 10, with two in each set. A set of the first telescopic rods 10 and a set of racks 8 arranged inside the movable slot 3 are arranged in a staggered up-and-down position. There are two auxiliary clamping plates 5, with two in each set. The connection between the rack 8 and the push block 9 forms an "L" - shaped structure. The height of the rotating member 4 is less than the height of the auxiliary clamping plate 5. When the first telescopic rod 10 performs a front-back telescopic action, the rack 8 connected integrally with the push block 9 will perform a synchronous front-back movement operation, thereby providing a relative thrust to the toothed ring 7.

[0023] Working process: All the electric energy required when the tooling equipment in the present utility model starts and runs comes from an external power source. When it is necessary to clamp and fix a square graphite crucible, first, when one side end of the square graphite crucible abuts against the left - hand side set of auxiliary clamping plates 5, the tooling equipment can control a set of the second telescopic rods 13 to stretch from right to left with the connecting block 12 and the movable clamping plate 14, so that a set of auxiliary clamping plates 5 provided at one side end of the movable clamping plate 14 presses against the other side end of the square graphite crucible, thus achieving the rapid clamping and fixing of the square graphite crucible. Before the tooling equipment needs to perform a clamping and fixing operation on a cylindrical graphite crucible, the tooling equipment can simultaneously control the two sets of the first telescopic rods 10 arranged in a staggered up - and - down manner to shorten and stretch. While the push block 9 and the rack 8 are synchronously stretched and moved, the toothed ring 7 will, after being stressed, drive the auxiliary clamping plate 5 to flip and rotate towards the center position of the top surface of the base 1 through the rotating shaft 6 and the rotating member 4. A set of toothed rings 7 will also form a "V" - shaped clamping groove structure after unfolding in the same direction, so that the entire tooling equipment can clamp and fix the cylindrical graphite crucible through a set of fixed "V" - shaped clamping groove structures and a set of movable "V" - shaped clamping groove structures, thus facilitating the entire graphite crucible processing tooling to achieve the purpose of adaptive clamping and fixing.

[0024] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
