Description

Technical Field

[0001] This utility model relates to the field of equipment installation, specifically to an adjustable-width material positioning frame. Background Technology

[0002] In modern industrial production, with the increasing demands for product quality and production efficiency, the accuracy and stability of material positioning have become crucial. Material positioning frames are devices used to fix and position materials, playing an important role in various production and processing scenarios and being widely used in mold manufacturing, industrial production, laboratories, and many other fields.

[0003] In industrial production, clamping blocks, clamping devices, or adsorption devices on material positioning frames are commonly used to fix materials in place, ensuring that the materials do not shift or shake during processing or assembly, thereby reducing processing errors and improving the accuracy of processing dimensions. The emergence of material positioning frames has greatly improved production efficiency.

[0004] However, most existing material positioning racks are designed for materials of specific shapes, sizes and types, and have poor versatility. If it is necessary to position materials of different specifications or shapes, different positioning racks may need to be replaced, which increases costs and personnel burden. Therefore, improvements are made to the existing material positioning racks. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide an adjustable-width material positioning frame to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjustable-width material positioning frame, including a base, a guide rail fixedly mounted on the base with the same length as the base, a limit structure slidably connected to the guide rail, and a positioning mechanism slidably connected to the guide rail for clamping materials during processing. A first slider is mounted at the bottom of the positioning mechanism, and a transmission device is fixedly mounted on the first slider. Two sets of clamping blocks are mounted on the first slider, and the bottom of the clamping blocks is connected to the first slider through the transmission device for adjusting the distance between the two sets of clamping blocks. A connecting mechanism is mounted on the top of the two sets of clamping blocks, and the connecting mechanism is provided with a connecting plate.

[0007] By adopting the above technical solution and adjusting the distance between the two sets of clamping blocks, the positioning frame can fix materials of different sizes or shapes, thereby enhancing the versatility of the positioning frame. During production and use, there is no need to spend a lot of time and effort to replace the dedicated positioning frame, thus improving the utilization rate of the equipment and reducing the production cost of designing and manufacturing dedicated positioning frames.

[0008] Furthermore, the top of the guide rail has multiple sets of threaded holes at equal intervals, and the guide rail has an I-shaped cross-section. The limiting structure consists of a limiting block and bolts. The bottom of the limiting block has a slider corresponding to the V-shaped grooves on both sides of the guide rail. The guide rail and the limiting block are threadedly connected to the threaded holes on the top by bolts.

[0009] By adopting the above technical solution, users can easily adjust the position of the limit mechanism during the processing and production process, and can also increase or decrease the number of limit mechanisms according to processing needs.

[0010] Furthermore, the top of the first slider has two sets of slider grooves. The transmission device consists of a fixed nut, a double-acting lead screw, and a handwheel. The double-acting lead screw is installed in the middle of the transmission device, and one end of the double-acting lead screw is fixedly connected to the first slider through the fixed nut. The other end of the double-acting lead screw is movably connected to the first slider through the handwheel for adjusting the rotation of the double-acting lead screw. Two sets of second sliders are movably installed on the double-acting lead screw in the slider grooves, and the clamping blocks are fixedly connected to the transmission device through the second sliders for adjusting the distance between the two sets of clamping blocks.

[0011] By adopting the above technical solution and setting a handwheel, users can easily adjust the rotation of the bidirectional lead screw, thereby improving convenience and accuracy.

[0012] Furthermore, both sets of clamping blocks have a first clamping surface vertically opened at their ends, and both sets of clamping blocks have a second clamping surface opened on their outer walls. The second clamping surface is designed with an inclined surface. A set of extension blocks is installed at one end of the top of each clamping block, and the extension blocks at the top of the two sets of clamping blocks are staggered.

[0013] By adopting the above technical solution, when the distance between the two sets of clamping blocks is adjusted according to the material to be positioned, the extension blocks of the two sets of clamping blocks are connected to each other to maintain the stability of the clamping blocks.

[0014] Furthermore, the top of the connecting plate has a through hole, which is designed as a cylindrical threaded hole. An adjusting screw is movably connected to the middle of the connecting plate for threaded connection with the through hole. The top of the adjusting screw has a polygonal design with a diameter larger than the screw itself, for rotating the adjusting screw.

[0015] By adopting the above technical solution, the material is fixed by tightening the adjusting screw. The setting of the connecting plate can ensure that the adjusting screw applies sufficient clamping force to the top of the material, and prevent the material from shifting during processing.

[0016] Furthermore, both sides of the connecting plate are provided with through slots corresponding to the extension blocks, and the two sets of clamping blocks and the connecting plate are connected to each other through the extension blocks and through slots.

[0017] By adopting the above technical solution, and through the cooperation of the extended block and the through groove, displacement of the clamping block is avoided during movement, thus ensuring the stability of the clamping block.

[0018] Furthermore, two sets of sliding shaft seats are fixedly installed on the connecting plate, and fixed shaft seats are fixedly installed on the top of both sets of clamping blocks. The fixed shaft seats on the top of the two sets of clamping blocks are staggered. The sliding shaft seats and fixed shaft seats are connected to each other by a shaft, and the shaft length is greater than the distance between the sliding shaft seats and the fixed shaft seats. A baffle is fixedly connected to the other end of the shaft. The baffle is cylindrical in shape, and the bottom of the baffle does not touch the top of the clamping block. A spring is connected between the sliding shaft seats and the baffle.

[0019] By adopting the above technical solution, the baffle is used to apply pressure to the spring, thereby ensuring a stable connection between the connecting plate and the clamping block, and preventing the adjusting screw from shifting, which would affect the fixing effect of the positioning mechanism on the material.

[0020] In summary, the present invention has the following main advantages:

[0021] This invention features a positioning mechanism that allows material to be placed into contact with the second clamping surface when the distance between the two sets of clamping blocks is closest. An adjusting screw applies pressure to the material, fixing its position and preventing displacement or movement during processing. This reduces processing errors and improves production efficiency. A handwheel rotates a bidirectional lead screw, shifting the two sets of clamping blocks to either side, allowing adjustment based on material size or shape. The material is then placed in and clamped by the first clamping surface, with the adjusting screw further securing its position. This enhances the versatility of the positioning frame, eliminating the need for time and effort to replace dedicated positioning frames during production. This improves equipment utilization and reduces the production costs of designing and manufacturing dedicated positioning frames. Furthermore, the cooperation between the guide rail and the bottom slider of the positioning mechanism allows for adjustment of the number and position of the positioning mechanism according to processing requirements, enabling quick replacement and easy maintenance.

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0028] The embodiments of this utility model will be described below based on its overall structure.

[0029] An adjustable-width material positioning frame, such as Figure 1 - Figure 4 As shown, it includes a base 1.

[0030] Specifically, a guide rail 11 is fixedly installed on the base 1, and the length of the guide rail 11 is the same as the length of the base 1. A limit structure 2 is slidably connected to the guide rail 11, which restricts the position of the positioning mechanism 3, thereby ensuring that the positioning mechanism 3 cannot move during processing. The positioning mechanism 3 is slidably connected to the guide rail 11 for clamping materials during processing. A first slider 31 is installed at the bottom of the positioning mechanism 3. The cooperation between the first slider 31 and the guide rail 11 enables the rapid assembly of the positioning mechanism 3, improving the work efficiency in processing and production. A transmission device 32 is fixedly installed on the first slider 31. Two sets of clamping blocks 33 are installed on the slider 31, and the bottom of the clamping blocks 33 is connected to the first slider 31 through the transmission device 32. This is used to adjust the distance between the two sets of clamping blocks 33. By adjusting the distance between the two sets of clamping blocks 33, the positioning frame can fix materials of different sizes or shapes, thereby enhancing the versatility of the positioning frame. During production and use, there is no need to spend a lot of time and effort to replace the special positioning frame, thereby improving the utilization rate of the equipment and reducing the production cost of designing and manufacturing special positioning frames. A connecting mechanism 35 is installed on the top of the two sets of clamping blocks 33, and the connecting mechanism 35 is provided with a connecting plate 352.

[0031] Please see Figure 1 - Figure 4The top of the guide rail 11 has multiple sets of threaded holes at equal intervals, allowing the user to adjust the position of the positioning mechanism 3 according to processing requirements during production. The guide rail 11 has an I-shaped cross-section. The limiting structure 2 consists of a limiting block 21 and bolts 22. The bottom of the limiting block 21 has a slider corresponding to the V-shaped grooves on both sides of the guide rail 11, making it easy for the user to adjust the position of the limiting structure 2 during processing. The number of limiting structures 2 can be increased or decreased according to processing requirements. The guide rail 11 and the limiting block 21 are threadedly connected to the threaded holes on the top by bolts 22. By fixing the position of the limiting structure 2, the position of the positioning mechanism 3 is fixed.

[0032] Please see Figure 1 - Figure 4 The first slider 31 has two sets of slider grooves 311 at its top, allowing the second slider 334 to slide a certain distance, thereby driving the clamping block 33 to move. The transmission device 32 consists of a fixing nut 321, a double-acting screw 322, and a handwheel 323. The double-acting screw 322 is installed in the middle of the transmission device 32, and one end of the double-acting screw 322 is fixedly connected to the first slider 31 by the fixing nut 321, thereby ensuring that the double-acting screw 322 provides a certain supporting force to the second slider 334. The other end of the double-acting screw 322 is connected to the handwheel 323. The wheel 323 is movably connected to the first slider 31 and is used to adjust the rotation of the bidirectional lead screw 322. The handwheel 323 facilitates the user's adjustment of the rotation of the bidirectional lead screw 322, thereby improving convenience and accuracy. Two sets of second sliders 334 are movably mounted on the bidirectional lead screw 322 in the slider groove 311, and the clamping block 33 is fixedly connected to the transmission device 32 through the second sliders 334. This is used to adjust the distance between the two sets of clamping blocks 33, so that the positioning mechanism 3 can be adjusted according to different processing requirements, thereby enhancing the versatility of the positioning frame.

[0033] Please see Figure 1 - Figure 4 Both sets of clamping blocks 33 have a first clamping surface 331 vertically opened at their ends, so that the positioning frame can be used to fix materials with rectangular cross-sections. Both sets of clamping blocks 33 have a second clamping surface 332 opened on their outer walls, so that the positioning frame can be used to fix materials with circular or triangular cross-sections. The second clamping surface 332 is designed with an inclined surface, so that the clamping blocks 33 can clamp materials of different sizes that need to be positioned. A set of extension blocks 333 is installed at one end of the top of the clamping blocks 33, and the extension blocks 333 at the top of the two sets of clamping blocks 33 are staggered. When the distance between the two sets of clamping blocks 33 is adjusted according to the material to be positioned, the extension blocks 333 of the two sets of clamping blocks 33 are connected to each other to maintain the stability of the clamping blocks 33.

[0034] Please see Figure 1 - Figure 4The connecting plate 352 has a through hole 353 at its top, and the through hole 353 is designed as a cylindrical threaded hole. An adjusting screw 34 is movably connected to the middle of the connecting plate 352 for threaded connection with the through hole 353. The material is fixed by tightening the adjusting screw 34. The setting of the connecting plate 352 can ensure that the adjusting screw 34 applies sufficient clamping force to the top of the material to prevent the material from shifting during processing. The top of the adjusting screw 34 has a polygonal design with a diameter larger than the screw, which is used to rotate the adjusting screw 34. The polygonal design of the top of the adjusting screw 34 makes it easier and more convenient for the user to rotate the adjusting screw 34.

[0035] Please see Figure 1 - Figure 4 Both sides of the connecting plate 352 are provided with through slots 351 corresponding to the extension block 333. The two sets of clamping blocks 33 and the connecting plate 352 are connected to each other through the extension block 333 and the through slots 351. Through the cooperation of the extension block 333 and the through slots 351, the clamping block 33 is prevented from shifting during movement, thus ensuring the stability of the clamping block 33.

[0036] Please see Figure 1 - Figure 4 Two sets of sliding bearing seats 354 are fixedly installed on the connecting plate 352, and fixed bearing seats 356 are fixedly installed on the top of the two sets of clamping blocks 33. The fixed bearing seats 356 on the top of the two sets of clamping blocks 33 are staggered. The sliding bearing seats 354 and the fixed bearing seats 356 are connected to each other by a shaft, which further ensures the stability between the connecting plate 352 and the clamping blocks 33, thereby preventing the connecting plate 352 or the clamping blocks 33 from shifting or shaking during the processing. The shaft length is greater than the distance between the sliding bearing seats 354 and the fixed bearing seats 356, and a baffle 355 is fixedly connected to the other end of the shaft. The baffle 355 is cylindrical and its bottom does not touch the top of the clamping block 33. A spring 357 is connected between the sliding bearing seats 354 and the baffle 355, so that the baffle 355 applies pressure to the spring 357 to ensure the stable connection between the connecting plate 352 and the clamping blocks 33 and to prevent the adjusting screw 34 from shifting, thereby affecting the fixing effect of the positioning mechanism 3 on the material.

[0037] The working principle of this utility model is as follows: When the user uses this equipment to position materials, the positioning mechanism 3 first needs to be slidably installed and fixed in a suitable position by the first slider 31 at the bottom and the guide rail 11. The positioning mechanism 3 can be quickly assembled by the cooperation between the first slider 31 at the bottom of the positioning mechanism 3 and the guide rail 11. The limiting block 21 is fixedly installed on both sides of the positioning mechanism 3 by bolt 22, thereby restricting the positioning mechanism 3 and ensuring that the positioning mechanism 3 cannot move during use.

[0038] When the user fixes a material with a rectangular cross-section, the user needs to turn the handwheel 323 to move the bidirectional lead screw 322. The rotation of the bidirectional lead screw 322 drives the two sets of second sliders 334 to move horizontally. At the same time, the clamping blocks 33 fixedly connected to the second sliders 334 also move in the corresponding direction, thereby expanding or shrinking the distance between the two sets of clamping blocks 33. This allows the clamping blocks 33 to clamp materials of different sizes and shapes. When the two sets of clamping blocks 33 move, the extension blocks 333 installed at the ends of the clamping blocks 33 will cooperate with the through slots 351 opened in the connecting plate 352 to prevent the clamping blocks 33 from shifting during the movement. At the same time, the fixed shaft seats 356 set at the top of the two sets of clamping blocks 33 drive the shaft to move in the sliding shaft seats 354, thereby using the baffle 355 to press the spring 357, thereby ensuring the stable connection between the connecting plate 352 and the clamping blocks 33 and preventing the adjusting screw 34 from shifting, which would affect the fixing effect on the material.

[0039] When fixing materials with circular or triangular cross-sections, the user adjusts the distance between the two sets of clamping blocks 33 to a suitable distance by rotating the handwheel 323, places the material in and it into contact with the second clamping surface 332, and then rotates the bottom of the adjusting screw 34 to the top surface of the material to apply pressure to the material, thereby fixing the material and reducing the positional deviation of the material during processing. When it is necessary to position rectangular, polygonal or other irregularly shaped materials, the user adjusts the distance between the two sets of clamping blocks 33 to a suitable distance by rotating the handwheel 323, places the material in and it into contact with the first clamping surface 331. After the first clamping surface 331 of the two sets of clamping blocks 33 clamps the material, the user rotates the bottom of the adjusting screw 34 to tighten it to the top surface of the material, thereby further fixing the material and preventing the material from shifting or shaking during processing.
