Description

Technical Field

[0001] The present invention relates to the technical field of tooling fixtures, and more specifically, to a tooling fixture with good limiting effect. Background Art

[0002] The guide assembly is a device that is installed before and after the roll pass during the section steel rolling process to help the rolled piece enter and exit the roll pass accurately and stably in a predetermined direction and state. It is mainly divided into two types: rolling guide and sliding guide.

[0003] After the guide assembly is installed, it needs to maintain a certain distance from the rolling mill. Currently, the guide assembly is often clamped and fixed using a tooling fixture. When the guide assembly is damaged, it needs to be disassembled, repaired, and then reinstalled. However, due to the lack of positioning and limiting structures in the existing tooling fixtures, it is necessary to re-measure the distance between the rolling guide assembly and the rolling mill during reinstallation, resulting in difficulties and low efficiency in installation.

[0004] In response to the problems in the related art, no effective solution has been proposed yet. Summary of the Invention

[0005] In response to the problems in the related art, the present invention proposes a tooling fixture with good limiting effect to overcome the above-mentioned technical problems existing in the existing related art.

[0006] To this end, the specific technical solution adopted by the present invention is as follows:

On the side of each of the two clamping plates away from each other, there are a number of limiting slide rods that penetrate and extend to the outside of the clamping plate. On both sides of the U-shaped frame, there are threaded extrusion rods threadedly connected thereto. On the side of each of the two clamping plates away from each other, there are a number of springs connected to the inner walls on both sides of the U-shaped frame. At the bottom end inside the U-shaped frame, there are a pair of chutes. At the bottom end of each chute, there is a long slot. Inside each long slot, a number of elastic telescopic blocks are installed. In the middle of the top end of each elastic telescopic block, there is a groove. There is a connecting through slot connecting the two long slots. In the middle of the bottom end inside the U-shaped frame, there is a storage slot. In the middle of the bottom end of the storage slot, there is a long-shaped through slot communicating with the connecting through slot. On the connecting through slot, there is a positioning and adjusting member slidably connected thereto.

[0008] Preferably, the positioning and adjusting member includes a long plate. A pair of pressing strips inserted into the grooves are provided at the rear end of the long plate. A pair of elastic telescopic columns are provided at the top end of the long plate. Sliding seats slidably connected to the inner wall above the connecting through groove are provided at the top ends of the two elastic telescopic columns. A pushing block extending into the interior of the receiving groove is provided in the middle of the top end of the long plate. A threaded rotating column extending into the interior of the long plate is provided in the middle of the top end of the pushing block. A long-shaped connecting plate movably connected to the bottom end of the threaded rotating column is provided at the bottom end of the threaded rotating column. A plurality of friction top columns extending above the long plate are provided at the top end of the long-shaped connecting plate.

[0009] Preferably, a first friction thin sheet matching the long plate is provided at the bottom end of the long plate. A second friction thin sheet is provided on each side of the two clamping plates close to each other.

[0010] Preferably, the threaded rotating column is always located in the receiving groove. The pressing strips and the long plate are both made of aluminum alloy.

[0011] Preferably, when not pressed by the pressing strips, the upper end of the elastic telescopic block extends into the sliding groove, while the pressing strips and the long plate are always located below the sliding groove.

[0012] Preferably, a pair of mounting plates are provided at the bottom end of the U-shaped frame. Both of the two mounting plates are L-shaped structures.

[0013] The beneficial effects of the present invention are as follows:

[0014] 1. By providing two sliding grooves with long grooves on the U-shaped frame and providing a plurality of elastic telescopic blocks that can block on each long groove, cooperating with the positioning and adjusting member, sliding the positioning and adjusting member, so that the pressing strips in the positioning sliding member are inserted into the corresponding number of grooves. By rotating the threaded rotating column, the pressing strips can be driven to move downward, thereby driving the corresponding number of elastic telescopic blocks to move downward and be received in the long grooves at the same time, so as to have a good positioning and limiting adjustment function, making it unnecessary to re-measure the distance between the guide assembly and the rolling mill when replacing the guide assembly, reducing the installation difficulty of the guide assembly, and effectively improving the installation efficiency of the guide assembly;

With reference to these contents, those of ordinary skill in the art should be able to understand other possible implementation manners and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0025] According to an embodiment of the present invention, a tooling fixture with good limiting effect is provided.

[0026] Embodiment 1;

[0027] AsFigures 1-5 As shown in the figure, a tooling fixture with good limiting effect according to an embodiment of the present invention includes a U-shaped frame 1. Clamping plates 2 are provided on both inner walls of the U-shaped frame 1. A number of limiting slide bars 3 that penetrate and extend to the outside of the clamping plates 2 are provided on one side of each of the two clamping plates 2 that are away from each other. Threaded extrusion rods 4 that are threadedly connected to the U-shaped frame 1 are provided on both sides of the U-shaped frame 1. A number of springs 5 that are connected to the inner walls of both sides of the U-shaped frame 1 are provided on one side of each of the two clamping plates 2 that are away from each other. A pair of chutes 6 are provided at the bottom end inside the U-shaped frame 1. A long groove 7 is provided at the bottom end of each chute 6. A number of elastic telescopic blocks 8 are installed inside each long groove 7. A groove 9 is provided in the middle of the top end of each elastic telescopic block 8. A connecting through groove 10 is connected between the two long grooves 7. A receiving groove 11 is provided in the middle of the bottom end inside the U-shaped frame 1. A long-shaped through groove 12 that communicates with the connecting through groove 10 is provided in the middle of the bottom end of the receiving groove 11. A positioning and adjusting member that is slidably connected to the connecting through groove 10 is provided on the connecting through groove 10.

[0028] Embodiment 2;

[0029] As Figures 1-5 As shown in the figure, for the tooling fixture with good limiting effect according to an embodiment of the present invention, the positioning and adjusting member includes a long plate 13. A pair of pressing strips 14 that are inserted into the grooves 9 are provided at the rear end of the long plate 13. A pair of elastic telescopic columns 15 are provided at the top end of the long plate 13. Sliding seats 16 that are slidably connected to the upper inner wall of the connecting through groove 10 are provided at the top ends of the two elastic telescopic columns 15. A pushing block 17 that extends into the inside of the receiving groove 11 is provided in the middle of the top end of the long plate 13. A threaded rotating column 18 that extends into the inside of the long plate 13 is provided in the middle of the top end of the pushing block 17. A long-shaped connecting plate 19 that is movably connected to the bottom end of the threaded rotating column 18 is provided at the bottom end of the threaded rotating column 18. A number of friction top columns 20 that extend above the long plate 13 are provided at the top end of the long-shaped connecting plate 19. When the positioning and adjusting member slides to a suitable position, during the sliding process, the pressing strips 14 are inserted into the corresponding number of grooves 9. Through extrusion, a plurality of elastic telescopic blocks 8 can be driven to move downward and be received in the long grooves 7 at the same time, so as to have the function of positioning and adjusting. When replacing the guide assembly, it is not necessary to re-measure the distance between the guide assembly and the rolling mill, which reduces the installation difficulty of the guide assembly and effectively improves the installation efficiency of the guide assembly. The threaded rotating column 18 is always located inside the receiving groove 11. The pressing strips 14 and the long plate 13 are both made of aluminum alloy. The aluminum alloy material has good strength and lighter weight, effectively reducing the weight borne by the elastic telescopic columns 15. Do not use too much force when using, so as to facilitate the use of the entire positioning and adjusting member. When not being pressed by the pressing strips 14, the upper ends of the elastic telescopic blocks 8 extend into the inside of the chutes 6. Since the upper ends of the elastic telescopic blocks 8 extend into the chutes 6, the guide assembly can be well blocked. And the pressing strips 14 and the long plate 13 are always located below the chutes 6, and the pressing strips 14 and the long plate 13 are both in a received state and will not interfere with the sliding installation of the guide assembly.

[0030] Embodiment three;

[0031] like Figures 1-5 As shown, according to the tooling fixture with good limiting effect in the embodiment of the present invention, the bottom end of the long plate 13 is provided with a friction sheet 21 matching it, which increases the friction resistance of the bottom surface of the long plate 13, thereby effectively improving the firmness of the long plate 13, and the two clamping plates 2 are provided with friction sheets 22 on the sides close to each other, which increases the friction force of the clamping surface of the clamping plate 2, thereby effectively improving the fixed installation of the clamping plate 2 on the guide assembly.

[0032] Embodiment 4:

[0033] like Figures 1-5 As shown, according to the fixture with good limiting effect in the embodiment of the present invention, a pair of mounting plates 23 are provided at the bottom end of the U-shaped frame 1, and both mounting plates 23 are L-shaped structures, which play a good role in fixing and installing the entire fixture.

[0034] In order to facilitate understanding of the above technical solutions of the present invention, the working principle or operation mode of the present invention in the actual process is described in detail below.

[0035] In actual application, push the push block 17 to drive the entire positioning adjustment member to slide along the connecting groove 10. During the sliding process, the long strip 14 is pressed to pass through different numbers of grooves 9 in sequence, and the spacing between the guide assembly and the rolling mill is adjusted. After the adjustment is completed, the threaded screw 18 is rotated. Since the long connecting plate 19 is movably connected to the threaded screw 18, under the limit of the friction top column 20, the long connecting plate 19 drives all the friction top columns 20 to move up together and tightly press on the upper part of the connecting groove 10, and the long plate 13 slowly moves down accordingly, so that the friction sheet 21 on the bottom surface of the long plate 13 is tightly pressed on the lower part of the connecting groove 10. The long strips 14 and the long plates 13, so the two pressing long strips 14 move down and squeeze the elastic telescopic block 8 just below them. After completion, slide along the slide groove 6 and insert into the guide assembly until the guide assembly contacts the elastic telescopic block 8, rotate the threaded extrusion rod 4, and push the two clamping plates 2 to approach each other, so that the friction sheet 22 on the clamping plate 2 is finally tightly clamped on both sides of the guide assembly, thereby realizing the fixed installation of the guide assembly, and the limiting effect is good. When the guide assembly is damaged, the guide assembly needs to be disassembled. When reinstalling, there is no need to remeasure the distance between the guide assembly and the rolling mill, which greatly reduces the installation difficulty of the guide assembly, thereby effectively improving the installation efficiency of the guide assembly.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
