Description

Technical Field

[0001] The utility model relates to the technical field of fixed jigs, in particular to a jig for irregular pig iron. Background Art

[0002] During the processing of pig iron, it needs to be fixed. If its shape is relatively regular, it can be fixed by existing horizontal and vertical jigs. However, if its shape is irregular, the existing jigs will not be able to fix it, and then other auxiliary structures need to be used to clamp it. Moreover, due to the irregular shape, the auxiliary structures used also need to be changed. Moreover, for such irregular pig iron, the fixing positions and the number of fixing points are also different. Therefore, when actually clamping it, it is difficult to achieve a stable clamping effect. Summary of the Utility Model

[0003] To solve the problem that the conventional jig cannot stably clamp irregular pig iron, the utility model provides a jig for irregular pig iron.

[0004] The technical solution of the utility model is as follows:

[0005] A jig for irregular pig iron, including a bottom support, an upper support frame is arranged above the bottom support, and an upper support frame is detachably arranged at intervals above the upper support frame;

[0006] Both the lower support frame and the upper support frame are annular and horizontally arranged;

[0007] A plurality of pressing jigs are arranged between the lower support frame and the upper support frame. The pressing jigs can move along the lower support frame and the upper support frame, and include a movable contact rod. The moving direction of the contact rod passes through the center of the lower support frame. The contact rods of the plurality of pressing jigs can fix the same pig iron at the same time.

[0008] Different from the existing conventional jigs, the number of pressing jigs of this device can be freely set, and the fixing point positions can be freely selected around the lower support frame. Therefore, when dealing with the structure of irregular pig iron, it can be fixed at different positions with different numbers of pressing jigs according to requirements.

[0009] The connection method between the lower support frame and the upper support frame is that a plurality of socket seats are circumferentially arranged on the lower support frame, and socket holes are arranged on the upper support frame at the positions of the socket seats, and a locking member is arranged at one end of the socket seat extending relative to the socket hole. If the heights of the socket seats are different, the interval height between the lower support frame and the upper support frame will be different.

[0010] In order to limit the position, the adjacent surfaces of the lower support frame and the upper support frame are provided with an annular notch, and the annular notch is located on the side close to the center. The clamping fixture includes a movable block arranged at the annular notch, and the interference rod passes through the movable block and is connected to the movable block by a thread. When in use, the clamping fixture can be limited, and when the interference rod extends toward the center, once it interferes with the pig iron, it will cooperate with the support frame to fix it. If the interference rod is continued to be twisted, the supporting effect will be achieved, and in order to prevent the pig iron from rotating, the contact surface of the clamping fixture and the lower support frame and the upper support frame is a rough surface to increase the friction.

[0011] As a preferred solution, the movable block cannot move away from the central axis of the lower support frame, so as to be able to contact and press the pig iron.

[0012] In order to facilitate the adjustment of the position of the movable block, the movable block is extended at both ends close to and away from the center of the lower support frame relative to the lower support frame.

[0013] As a preferred solution, the interference rod is horizontally arranged and the moving plane is a horizontal plane.

[0014] The specific structure of the bottom support is that the bottom support comprises a reference plate, an annular support is arranged on the reference plate, and the lower support frame is fixed on the annular support.

[0015] In order to improve the suitability for cast iron structures, an elastic pad is provided at one end of the abutment rod close to the center of the lower support frame.

[0016] The beneficial effect of the utility model is that the utility model is a clamp for irregular pig iron, and a circular track is constructed by a lower support frame and an upper support frame. Then, a plurality of clamps can be freely arranged at the circular track for fixing the pig iron, and the fixed position and the fixed number of the clamps relative to the pig iron can be freely selected. Therefore, to a certain extent, the fixed point and the fixed number can be freely selected according to the specific structure of the irregular pig iron to achieve the fixing effect thereof, and the above structure is not limited to clamping irregular structures, but can also be used for fixing conventional structures such as conventional rectangles or circles.

[0017] By reading the detailed description of the preferred embodiment below, the scheme and advantages of the present application will become clear to those skilled in the art. The accompanying drawings are only used to illustrate the preferred embodiment and are not considered to be limiting of the present invention.

[0024] The components represented by each reference numeral in the figure are:

[0025] 1. Bottom support; 11. Reference flat plate; 12. Ring support; 2. Lower support frame; 21. Socket; 22. Locking member; 3. Upper support frame; 4. Pressing fixture; 41. Movable block; 42. Contact rod; 5. Elastic pad. Specific embodiments

[0026] As Figure 4 , 5 shown, a fixture for irregular pig iron includes a bottom support 1, and the specific structure of the bottom support 1 is that the bottom support 1 includes a reference flat plate 11, the reference flat plate 11 is placed on a reference plane, and then a ring support 12 is arranged on the reference flat plate 11, and the lower support frame 2 is fixed on the ring support 12. The purpose of arranging the ring support 12 is to increase the height of the lower support frame 2. For some pig iron structures with certain heights, if the fixing position is relatively low, its stability is poor, while appropriately increasing the fixing height can effectively improve the above problems.

[0027] That is, as Figure 1 shown, a lower support frame 2 is arranged above the bottom support 1, and an upper support frame 3 is detachably arranged at intervals above the lower support frame 2. The combination of the two structures is to construct a frame track, and then the irregular pig iron can be fixed by arranging a fastening structure above it.

[0028] It should be noted that in the above structure, both the lower support frame 2 and the upper support frame 3 are annular and horizontally arranged, and the connection method between the lower support frame 2 and the upper support frame 3 is that a plurality of sockets 21 are arranged circumferentially on the lower support frame 2. Generally, two can be arranged at symmetric positions, and the upper support frame 3 is provided with socket holes at the positions of the sockets 21, and a locking member 22 is arranged at one end of the socket 21 extending relative to the socket hole. If the heights of the sockets 21 are different, the interval height between the lower support frame 2 and the upper support frame 3 will be different. The locking member 22 can be a nut. Correspondingly, the end of the socket 21 can be provided with a thread to cooperate with the locking member 22 for application, which is convenient for disassembly.

[0029] Most importantly, a plurality of pressing jigs 4 are arranged between the lower support frame 2 and the upper support frame 3. First of all, the number of the pressing jigs 4 is uncertain, and generally at least three. During use, the number and position need to be selected according to the specific structure of the irregular pig iron. Therefore, the pressing jigs 4 can be used as detachable structures for convenient free selection. And the pressing jigs 4 can move along the lower support frame 2 and the upper support frame 3, so as to be moved to a certain position according to requirements to support the selected fixing points. And the above-mentioned pressing jigs 4 include movable resisting rods 42, and the moving direction of the resisting rods 42 passes through the center of the lower support frame 2. Therefore, during the circular movement, it will always face the center and will not change. And the resisting rods 42 of the plurality of pressing jigs 4 can fix the same pig iron at the same time, and the irregular pig iron can be resisted from multiple positions to complete the fixation of the above-mentioned pig iron.

[0030] Through the above structure, it can be realized that, different from the existing conventional jigs, the number of the pressing jigs 4 of the present device can be freely set, and the position of the fixing points can be freely selected around the lower support frame 2. Therefore, when dealing with the structure of irregular pig iron, it can be fixed at different positions by different numbers of pressing jigs 4 according to requirements, and it can also be fixed for the existing regular pig iron structure, with strong applicability. And it can be seen from the above structure that the above structural parts can be freely disassembled and replaced, so it is also convenient for maintenance.

[0031] As a preferred embodiment, as Figures 1-5 shown, the specific structure of the above structure is as follows. First of all, for the purpose of limiting, annular notches are provided on the adjacent surfaces of the lower support frame 2 and the upper support frame 3. Referring to Figure 1 and Figure 5 it can be seen that the annular notches are located on the side close to the center, and the pressing jigs 4 include movable blocks 41 arranged at the corresponding annular notches. The structure of the movable blocks 41 is matched with the above-mentioned annular notches. As Figure 5 shown, it can be limited. By extending the resisting rods 42, it can press the irregular pig iron, the lower support frame 2 and the upper support frame 3, so as to achieve the fixing effect. And after fixation, the above-mentioned movable blocks 41 cannot move up and down, and there is only the possibility of rotating horizontally. Therefore, in order to prevent the above-mentioned movable blocks 41 from rotating with the pig iron, the contact surfaces of the pressing jigs 4 with the lower support frame 2 and the upper support frame 3 are rough surfaces to increase the friction force. After pressing, when the friction force between the movable blocks 41 and the lower support frame 2 and the upper support frame 3 is large enough, the above-mentioned movable blocks 41 will not move, and correspondingly, the above-mentioned irregular pig iron will be fixed by a plurality of pressing jigs 4.

[0032] And in the above structure, as Figure 4 、 5As shown, the abutment rod 42 penetrates the movable block 41 and is connected to the movable block 41 by a thread. When in use, the clamping fixture 4 can be limited. When the abutment rod 42 extends toward the center, once it abuts against the pig iron, it will cooperate with the support frame to fix it. If the abutment rod 42 is further twisted, the supporting effect will be achieved, and the method is to rotate the abutment rod 42 by a tool.

[0033] Finally, it should be noted that the movable block 41 cannot move away from the central axis of the lower support frame 2 so as to be able to contact and compress the pig iron. When in use, the above-mentioned contact rod 42 is twisted with the tool, and its end extends inward, pushing the pig iron until it cannot rotate and then contacts the lower support frame 2 and the upper support frame 3, and finally fixes with them to reach a fixed state.

[0034] In order to facilitate the adjustment of the position of the movable block 41 , the movable block 41 is extended outward at both ends close to and away from the center of the lower support frame 2 relative to the lower support frame 2 .

[0035] For the convenience of use, the abutment rod 42 is arranged horizontally and the moving plane is a horizontal plane. In order to improve the suitability for cast iron structure, an elastic pad 5 is arranged at one end of the abutment rod 42 near the center of the lower support frame 2.
