Abstract
Description
Technical Field
[0001] This utility model relates to the field of material handling fixture technology, and in particular to a material handling fixture with an adjustable structure. Background Technology
[0002] Material placement fixtures are auxiliary tools used for material placement, positioning, and processing. They are widely used in the manufacturing industry to improve production efficiency, ensure processing accuracy, and adapt to materials of different sizes and shapes.
[0003] However, the adjustment accuracy of existing material handling fixtures is often insufficient to meet the needs of high-precision production. Some fixture adjustment mechanisms use simple slots, sliders, and other structures. The size of the fixture is changed by manually moving or inserting the slots at different positions. This adjustment method has a large error, which may affect the quality and performance of the product.
[0004] For example, when a rubber products factory produces a type of rubber strip, the operator manually moves the slider to different slots in the traditional fixture to change the size of the fixture to accommodate the production of rubber strips of different specifications. In actual production, due to inaccurate adjustment, the rubber raw material placed in the mold may be misaligned or unevenly distributed. After the rubber raw material is vulcanized in the mold, the produced rubber strip may have dimensional deviations. Utility Model Content
[0005] This utility model discloses a material handling fixture with an adjustable structure, aiming to solve the problem that the adjustment accuracy of existing material handling fixtures often fails to meet the needs of high-precision production. Some fixtures use simple slots, sliders, and other structures for adjustment, and the size of the fixture is changed by manually moving or inserting the slots at different positions. This adjustment method has a large error, which may affect the quality and performance of the product.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A material handling fixture with an adjustable structure includes a base with two handles on its top outer wall. It also includes: a first adjusting mechanism located on the top outer wall of the base, comprising two first knobs; two connecting grooves and three limiting openings on the top outer wall of the base; three mounting grooves inside the base; the connecting grooves communicating with the mounting grooves; a threaded rod on one side of the outer wall of each of the first knobs; three moving blocks connected to the circumference of the threaded rod by threads; one end of the threaded rod connected to the other side of the outer wall of the base by a bearing; and a limiting plate between every two moving blocks; and a second adjusting mechanism located inside the base.
[0008] By adopting the above technical solution, the width of the limiting port can be precisely adjusted according to the size of the material, improving the accuracy and stability of material positioning. Specifically, in use, by simultaneously rotating two first knobs in the same direction, the threaded rods connected to them are driven to rotate. Since the threaded rods and moving blocks are connected by threads, the rotation will cause the moving blocks to move along the axial direction of the threaded rods. Each knob controls three moving blocks, and the two knobs control a total of six moving blocks, forming a symmetrical distribution. When the moving blocks move in the mounting groove, they push the limiting plate to slide on the inner wall of the mounting groove. The threaded transmission achieves millimeter-level fine adjustment. The limiting plate, through the guiding effect of the mounting groove, can precisely control the effective width of the limiting port, adapting to materials of different specifications.
[0009] In a preferred embodiment, the length of the limiting plate is equal to the length of the limiting opening, and the length of the moving block is greater than the width of the limiting opening.
[0010] In this design, the length of the limiting plate matches the length of the limiting opening to ensure that it can completely cover the limiting opening. The length of the moving block is greater than the width of the limiting opening. Under normal conditions, the moving block is located in the mounting groove. At this time, the two moving blocks block the parts of the limiting opening that communicate with the connecting groove on both sides. When one side of the limiting plate is completely in contact with the inner wall of the limiting opening, the moving block still maintains its longer side to ensure that the moving block blocks the parts of the limiting opening that communicate with the connecting groove on both sides, thus preventing materials from entering the connecting groove.
[0011] In a preferred embodiment, the second adjustment mechanism includes two sets of limiting components and six second knobs. The limiting components include three adjusting rods and three limiting rods. One end of each adjusting rod is fixedly connected to a second knob. Both the adjusting rod and the limiting rod are located on the top outer wall of the moving block. The outer walls of two adjusting rods are provided with first sprockets, and the outer walls of two adjusting rods are provided with second sprockets. A first chain is provided between the two first sprockets, and a second chain is provided between the two second sprockets. The outer walls of the adjusting rods are threadedly connected to a mounting plate. The mounting plate is sleeved on the circumferential outer wall of the limiting rod. A pressure block is hinged to one side of the outer wall of the mounting plate.
[0012] When any adjusting rod is rotated, the pressure block is rotated 90 degrees, so that the pressure block is above the material. The first and second chains drive the other adjusting rods in the same group to rotate synchronously, realizing multi-rod linkage control. When the adjusting rod rotates, the mounting plate moves along the axial direction of the limit rod, i.e., in the up and down direction. The moving distance is precisely controlled by the thread pitch and the number of rotations. The pressure block fixed on one side of the mounting plate moves synchronously with the mounting plate. The material is released by the pressure change of the contact surface between the pressure block and the material, preventing the material from getting stuck in the limit port.
[0013] As described above, a material handling fixture with an adjustable structure includes a base with two handles on its top outer wall. It also includes: a first adjusting mechanism located on the top outer wall of the base, comprising two first knobs; two connecting grooves and three limiting openings on the top outer wall of the base; three mounting grooves inside the base; the connecting grooves communicating with the mounting grooves; a threaded rod on one side of the outer wall of each first knob; three moving blocks connected to the circumference of the threaded rod by threads; one end of the threaded rod connected to the other side of the outer wall of the base by a bearing; and a limiting plate between every two moving blocks; and a second adjusting mechanism located inside the base. This utility model provides a material handling fixture with an adjustable structure that allows for precise adjustment of the width of the limiting openings according to the material's size, thus improving the accuracy and stability of material positioning.

[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.
[0021] The material handling fixture with an adjustable structure disclosed in this utility model is mainly used in scenarios where the adjustment accuracy of existing material handling fixtures often fails to meet the requirements of high-precision production. Some fixtures use simple slots, sliders, and other structures for adjustment, and the size of the fixture is changed by manually moving or inserting the slots at different positions. This adjustment method has a large error, which may affect the quality and performance of the product.
[0022] Reference Figure 1 and Figure 2 A material handling fixture with an adjustable structure includes a base 1, with two handles on the top outer wall of the base 1, and further includes: a first adjusting mechanism located on the top outer wall of the base 1, the first adjusting mechanism including two first knobs 2, two connecting grooves 3 and three limiting ports 8 opened on the top outer wall of the base 1, three mounting grooves opened inside the base 1, the connecting grooves 3 communicating with the mounting grooves, a threaded rod 11 provided on one side outer wall of the first knob 2, three moving blocks 10 connected to the circumferential outer wall of the threaded rod 11 by threads, one end of the threaded rod 11 connected to the other side outer wall of the base 1 by a bearing, and a limiting plate 12 provided between every two moving blocks 10; and a second adjusting mechanism located inside the base 1.
[0023] The length of the limiting plate 12 is equal to the length of the limiting port 8, and the length of the moving block 10 is greater than the width of the limiting port 8. The length of the limiting plate 12 matches the length of the limiting port 8 to ensure that it can completely cover the limiting port 8. The length of the moving block 10 is greater than the width of the limiting port 8. Under normal conditions, the moving block 10 is located in the mounting groove. At this time, the two moving blocks 10 block the parts of the limiting port 8 that communicate with the connecting groove 3 on both sides. When one side of the limiting plate 12 is completely attached to the inner wall of the limiting port 8, the moving block 10 still maintains its longer side to ensure that the moving block 10 blocks the parts of the limiting port 8 that communicate with the connecting groove 3 on both sides, thus preventing materials from entering the connecting groove 3.
[0024] In actual use, the six moving blocks 10 are symmetrically distributed along the center line of the base 1.
[0025] The limiting plate 12 is slidably connected to the inner wall of the mounting groove.
[0026] Specifically, by simultaneously rotating two first knobs 2 in the same direction, the threaded rods 11 connected to them are driven to rotate. Since the threaded rods 11 and the moving blocks 10 are connected by threads, the rotation will cause the moving blocks 10 to move axially along the threaded rods 11. Each knob controls three moving blocks 10, and the two knobs control a total of six moving blocks 10, forming a symmetrical distribution. When the moving blocks 10 move in the mounting groove, they push the limiting plate 12 to slide on the inner wall of the mounting groove. The threaded transmission achieves millimeter-level fine adjustment. The limiting plate 12 can accurately control the effective width of the limiting port 8 through the guiding effect of the mounting groove, adapting to materials of different specifications. This device can accurately adjust the width of the limiting port 8 according to the size of the material, improving the accuracy and stability of material positioning.
[0027] Reference Figure 3 and Figure 4 In a preferred embodiment, the second adjustment mechanism includes two sets of limiting components and six second knobs 5. The limiting components include three adjusting rods 17 and three limiting rods 6. One end of the adjusting rod 17 is fixedly connected to the second knob 5. The adjusting rods 17 and the limiting rods 6 are both located on the top outer wall of the moving block 10. The outer walls of the two adjusting rods 17 are provided with first sprockets 13 and second sprockets 14. A first chain 15 is provided between the two first sprockets 13 and a second chain 16 is provided between the two second sprockets 14. The outer walls of the adjusting rods 17 are connected to a mounting plate 4 by threads. The mounting plate 4 is sleeved on the circumferential outer wall of the limiting rod 6. A pressure block 7 is hinged to one side of the outer wall of the mounting plate 4.
[0028] It should be noted that the other end of the adjusting rod 17 is connected to the moving block 10 via a bearing.
[0029] The second sprocket 14 and the first sprocket 13 are distributed vertically along the axial position of the adjusting rod 17. The pressure block 7 has an "L" shape structure, in which the thickness of two pressure blocks 7 is less than the thickness of the other pressure block 7, and the bottom outer walls of the three pressure blocks 7 are located on the same horizontal plane. The first sprocket 13 and the second sprocket 14 provide the structural basis for realizing the adjustment function of the material handling fixture through transmission. This ensures that the first chain 15 and the second chain 16 can be smoothly wound around the first sprocket 13 and the second sprocket 14 to achieve stable power transmission. On the other hand, this layout reduces the space occupied by the first sprocket 13 and the second sprocket 14 in the horizontal direction, making the overall structure of the material handling fixture more compact. This is conducive to installation and use in a limited working space and improves space utilization. The "L" shape structure allows the pressure block 7 to better fit the top surface of the material when moving up and down, thereby quickly pushing the material out of the limiting port 8.
[0030] Specifically, when any adjusting rod 17 is rotated, the pressure block 7 is rotated 90 degrees, so that the pressure block 7 is above the material. The first chain 15 and the second chain 16 drive the other adjusting rods 17 in the same group to rotate synchronously, realizing multi-rod linkage control. When the adjusting rod 17 rotates, the mounting plate 4 moves up and down along the axial direction of the limiting rod 6. The moving distance is precisely controlled by the thread pitch and the number of rotations. The pressure block 7 fixed on one side of the mounting plate 4 moves synchronously with the mounting plate 4. Through the pressure change of the contact surface between the pressure block 7 and the material, the material is released to prevent the material from getting stuck in the limiting port 8.
[0031] Reference Figure 5 In a preferred embodiment, the bottom outer wall of the base 1 is provided with two anti-slip pads 18, which greatly enhances the friction between the material placement fixture and the placement surface. In actual use, whether placed on a smooth metal table, wooden table or other flat surface, the anti-slip pads 18 can effectively prevent the fixture from sliding or shifting during operation.
[0032] Working principle: In use, by simultaneously rotating the two first knobs 2 in the same direction, the threaded rods 11 connected to them are driven to rotate. Since the threaded rods 11 and the moving blocks 10 are connected by threads, the rotation will cause the moving blocks 10 to move axially along the threaded rods 11. Each knob controls three moving blocks 10, and the two knobs control a total of six moving blocks 10, forming a symmetrical distribution. When the moving blocks 10 move in the mounting groove, they push the limiting plate 12 to slide on the inner wall of the mounting groove. The threaded transmission achieves millimeter-level fine adjustment. The limiting plate 12 can accurately control the effective width of the limiting port 8 through the guiding effect of the mounting groove, adapting to materials of different specifications. The width of the limiting port 8 can be accurately adjusted according to the size of the material, improving the accuracy and stability of material positioning.
[0033] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
