Description

Technical Field

[0001] The present application relates to the technical field of clamps, and in particular to a multifunctional flat-nose pliers. Background Art

[0002] Currently, flat-nose pliers, also known as machine vises, are a general-purpose fixture commonly used to mount small workpieces. They are included as accessories with milling and drilling machines, fixed to the machine table to clamp workpieces for cutting. However, most traditional flat-nose pliers have only one station and can only hold one part or blank at a time for processing. This limited functionality makes them inconvenient to use, resulting in low processing efficiency and difficulty meeting the processing needs of enterprises.

[0003] Therefore, how to improve the existing flat-nose pliers to overcome the above-mentioned deficiencies is a problem that needs to be solved urgently by those skilled in the art. Summary of the Invention

[0004] One purpose of the present application is to provide a multifunctional flat-nose pliers with an ingenious layout, easy use, the ability to clamp multiple workpieces at the same time, and high processing efficiency.

[0005] To achieve the above objectives, the technical solution adopted in the present application is: a multifunctional flat-nose pliers, comprising a base, a driving member, a fixed block, a fastening block and at least one movable block; the fixed block is arranged on the base, and the fastening block and each movable block can be slidably arranged on the base left and right, and each movable block is located between the fixed block and the fastening block; the driving member is arranged on the fastening block and / or the base, and the driving member is used to drive the fastening block to slide left and right, and when the fastening block slides in a direction close to the fixed block, a clamping area for clamping a workpiece is formed between the fixed block and the corresponding movable block, between two adjacent movable blocks, and between the fastening block and the corresponding movable block.

[0006] Preferably, the multifunctional flat-nose pliers further include a guide rod, one end of which is mounted on the fixed block and the other end of which is mounted on the base. The fastening block and each of the movable blocks are each provided with guide holes extending therethrough, the guide holes being slidably connected to the guide rod. This has the advantage that the sliding limit between the guide rod and the guide holes limits the sliding movement of the fastening block and each of the movable blocks, thereby improving the sliding precision of the fastening block and each of the movable blocks.

[0007] Preferably, the movable block is divided into at least two modular units along the left-right direction, and the inner wall of the guide hole on each modular unit is provided with a notch extending outward, the notch being used to pass the guide rod, and the opening directions of the two adjacent notches on the left and right sides are staggered; the multifunctional flat-nose pliers further include a locking member, the locking member being used to lock the modular units. The advantages thereof are: on the one hand, when it is necessary to add or remove the movable block, it is only necessary to align the notch on the modular unit with the guide rod, so that the guide rod can be directly inserted into the corresponding guide hole, or directly removed from the corresponding guide hole, i.e., there is no need to first remove the guide rod, the fixing block (or fastening block) and the screw (when the driving member is a screw), thereby making the operation of adding or removing the movable block easier; and, because the opening directions of the two adjacent notches on the left and right sides are staggered, when each modular unit is locked by the locking member, the staggered arrangement of the notches can just prevent the guide rod from escaping from the notch or the guide hole. On the other hand, when it is necessary to adjust the distance between two adjacent clamping areas, the purpose of adjusting the distance between two adjacent clamping areas can be achieved by increasing or decreasing the total number of module units corresponding to the same moving block or replacing the thickness (i.e., the size in the left and right directions) of a single (or multiple) module unit.

[0008] Preferably, the opening directions of the notches on the same module unit are the same, and the opening directions of two adjacent notches are staggered in the vertical direction. This has the advantage that: for the module unit with the notch opening facing downward, it can be directly inserted downward from above the guide rod or directly removed upward; for the module unit with the notch opening facing upward, it can be directly inserted upward from below the guide rod or directly removed downward. Since, under the action of gravity, the tight fitting surface between the guide rod and the guide hole (i.e., the position prone to wear) is located on the upper side of the guide hole, the thickness of the module unit with the opening direction of the notch facing downward can be increased, and the thickness of the module unit with the opening direction of the notch facing upward can be reduced, thereby effectively increasing the contact area of ​​the tight fitting surface between the guide rod and the guide hole under the condition of the same width of the moving block, thereby delaying the wear of the guide rod and the guide hole; in addition, when the distance between the guide rod and the base is small, the smaller the thickness of the module unit with the opening direction of the notch facing upward, the easier it is to install the module unit from the gap between the guide rod and the base, that is, the module unit is first inserted into the gap between the guide rod and the base in a flat posture, and then rotated 90° to achieve installation; the reverse operation can be performed for disassembly.

[0009] Preferably, the guide rod is a cylindrical structure, and there are two guide rods, which are spaced apart in the front-to-back direction. The two notches on the same module unit are both located on the lower side of the module unit, and the opening directions of the two notches on the same module unit are staggered. When one of the guide rods enters the corresponding guide hole through the corresponding notch, the module unit can be rotated, so that the other guide rod enters the corresponding guide hole through the other notch. The advantages are: the cylindrical guide rod and the corresponding circular guide hole have low processing difficulty and high processing accuracy. In addition, this layout of the notches does not affect the installation of the module unit, and allows the upper side of the guide hole on each module unit to contact the guide rod, thereby fully increasing the total contact area of ​​the close-fitting surface between the guide hole and the guide rod, further delaying the wear of the guide rod and the guide hole. In addition, since the notch is located on the lower side of the module unit, the debris generated during the processing will not accumulate in the notch, thereby not affecting the sliding between the guide rod and the guide hole; similarly, the debris generated during the processing will not accumulate in the clearance hole, thereby not affecting the rotation of the screw rod.

[0010] Preferably, the same moving block is divided into at least three modular units, namely a left module, a right module, and at least one middle module. This arrangement allows the middle modules to be manufactured as standard components with varying or uniform thicknesses, allowing the number of middle modules to be increased or decreased as needed, thereby varying the width of the moving block.

[0011] Preferably, the locking member is a locking bolt, and each modular unit on the same movable block is locked together by at least one of the locking bolts, with both ends of the locking bolt concealed within the modular unit. This has the advantage of facilitating the locking of each modular unit, thereby allowing the modular units to be assembled to form the movable block. Furthermore, both ends of the locking bolt are concealed within the modular unit, preventing interference with other structures.

[0012] Preferably, the base is provided with a support block, and both the support block and the fixing block are provided with bolt holes and mounting holes for adapting to the guide rod, and the inner wall of the mounting hole is provided with an open slit extending outward therethrough; the multifunctional flat-nose pliers further include a fastening bolt, which is threadedly connected to the bolt hole, thereby reducing the gap in the open slit, thereby allowing the mounting hole to clamp the guide rod. This has the advantage that, before installing the fastening bolt, the presence of the open slit facilitates inserting the end of the guide rod into the mounting hole; after installing the fastening bolt, the gap in the open slit is reduced, allowing the mounting hole to fully clamp the guide rod, thereby achieving installation and fixation of the guide rod.

[0013] Preferably, the driving member includes a screw, the left end of which is rotatably connected to the fixed block, and the right end of which is rotatably connected to the base; threaded holes for threaded connection of the screw are provided on the left and right sides of the fastening block, and clearance holes for the screw to pass through are provided on the left and right sides of each of the movable blocks. This has the advantage that by driving the screw to rotate, the screw can drive the fastening block to slide left and right through the threaded holes. In addition, the screw does not take up excess space while providing a sufficiently long drive stroke; moreover, the screw can achieve self-locking when it stops rotating, resulting in a simple structure, easy use, and high stability.

[0014] Preferably, the multifunctional flat-nose pliers further include a bottom plate, and the base is detachably mounted on the bottom plate. This has the advantage that by mounting the bottom plate on a processing station and detachably connecting the base to the bottom plate, the base can be mounted, fixed, or removed, thereby facilitating assembly, disassembly, and replacement.

[0015] Preferably, the fastening block and each of the moving blocks are provided with fixing holes for installing special clamping tools. This has the advantage that special clamping tools can be installed through the fixing holes, thereby being able to clamp a wider variety of workpieces, which is suitable for enterprises with a large variety of workpieces and large quantities.

[0016] Compared with the prior art, the beneficial effects of the present application are: (1) since the driving member is used to drive the fastening block to slide left and right, and when the fastening block slides in the direction close to the fixed block, a clamping area for clamping the workpiece is formed between the fixed block and the corresponding moving block, between two adjacent moving blocks, and between the fastening block and the corresponding moving block; therefore, when one moving block is installed, one clamping area can be formed between the fixed block and the moving block, and between the fastening block and the moving block, that is, two clamping areas in total, thereby clamping two workpieces at the same time; when two moving blocks are installed, one clamping area can be formed between the fixed block and the corresponding moving block, between the two moving blocks, and between the fastening block and the corresponding moving block, that is, three clamping areas in total, thereby clamping three workpieces at the same time; and so on, the number of workpieces that can be clamped simultaneously by the multifunctional flat-nose pliers is S=N+1, where N is the number of moving blocks. That is to say, according to the actual processing needs of the enterprise, by increasing or decreasing the number of the moving blocks, the number of the workpieces that the flat-nose pliers can clamp at the same time can be increased or decreased, thereby meeting the actual processing needs of the enterprise, being more convenient to use and having higher processing efficiency; in addition, when it is necessary to process products of different models or categories, it is also possible to replace the moving blocks of different widths (width refers to the size of the moving block in the left and right directions) to adjust the distance between two adjacent clamping areas to adapt to products of different models or categories, and to have more diverse functions.

[0017] (2) Since the fixed block is arranged on the base, the fastening block and each of the movable blocks can be slidably arranged on the base left and right, and each of the movable blocks is located between the fixed block and the fastening block; therefore, when clamping the workpiece, it is only necessary to drive the fastening block to slide in the direction close to the fixed block through the driving member, so that each of the clamping areas can clamp the corresponding workpiece respectively; similarly, when the workpiece needs to be loosened after processing, it is only necessary to drive the fastening block to slide in the direction away from the fixed block through the driving member, so that each of the clamping areas can loosen the corresponding workpiece respectively. As can be seen from the above content, this structural layout is more clever, more convenient to use, and can save the number of driving members. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] Below, the present application is further described in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0037] In the description of the present application, it should be noted that for directional words, such as the terms "center", "transverse", "longitudinal", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc., indicating directions and positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operate in a specific direction, and cannot be understood as limiting the specific scope of protection of the present application. The terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. The terms "including" and "having" in the description and claims of the present application and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units that are not explicitly listed or inherent to these processes, methods, products or devices.

[0038] Example 1: Reference Figure 1 、 Figure 2 as well as Figure 4The present application provides a multifunctional flat-nose pliers, including a base 1, a driving member 2, a fixed block 3, a fastening block 4 and at least one movable block 5; the fixed block 3 is arranged on the base 1, and the fastening block 4 and each movable block 5 can be slidably arranged on the base 1 left and right, and each movable block 5 is located between the fixed block 3 and the fastening block 4; the driving member 2 is arranged on the fastening block 4 and / or the base 1, and the driving member 2 is used to drive the fastening block 4 to slide left and right, and when the fastening block 4 slides in a direction close to the fixed block 3, a clamping area for clamping a workpiece is formed between the fixed block 3 and the corresponding movable block 5, between two adjacent movable blocks 5, and between the fastening block 4 and the corresponding movable block 5.

[0039] Understandably, if Figure 4 As shown, when one moving block 5 is installed, a clamping area can be formed between the fixed block 3 and the moving block 5, and between the fastening block 4 and the moving block 5, that is, a total of two clamping areas, so that two workpieces can be clamped at the same time; when two moving blocks 5 are installed, a clamping area can be formed between the fixed block 3 and a corresponding moving block 5, between the two moving blocks 5, and between the fastening block 4 and a corresponding moving block 5, that is, a total of three clamping areas, so that three workpieces can be clamped at the same time; and so on, the number of workpieces that can be clamped simultaneously by the multifunctional flat-nose pliers is S=N+1, where N is the number of moving blocks 5. That is to say, according to the actual processing needs of the enterprise, by increasing or decreasing the number of movable blocks 5, the number of workpieces that the flat-nose pliers can clamp at the same time can be increased or decreased, thereby meeting the actual processing needs of the enterprise, being more convenient to use and having higher processing efficiency; in addition, when it is necessary to process products of different models or categories, it is also possible to replace movable blocks 5 of different widths (width refers to the size of the movable block 5 in the left and right directions) so as to adjust the distance between two adjacent clamping areas to adapt to products of different models or categories, and to make the functions more diverse.

[0040] In addition, if Figure 1 As shown, since the fixed block 3 is set on the base 1, the fastening block 4 and each movable block 5 can be slidably set on the base 1 left and right, and each movable block 5 is located between the fixed block 3 and the fastening block 4; therefore, when clamping the workpiece, it is only necessary to drive the fastening block 4 to slide in the direction close to the fixed block 3 through the driving member 2, so that each clamping area can clamp the corresponding workpiece respectively; similarly, when the workpiece needs to be loosened after processing, it is only necessary to drive the fastening block 4 to slide in the direction away from the fixed block 3 through the driving member 2, so that each clamping area can loosen the corresponding workpiece respectively. From the above content, it can be seen that this structural layout is more clever, more convenient to use, and can save the number of driving members 2.

[0041] The present application does not limit the sliding installation method of the fastening block 4 and each moving block 5. The following only provides a specific sliding installation method for reference: Figure 1 and Figure 2 As shown, the multifunctional flat-nose pliers further include a guide rod 6, one end of which is disposed on the fixed block 3, and the other end of which is disposed on the base 1. Guide holes 51 are provided on the left and right sides of the fastening block 4 and each movable block 5. The guide holes 51 are slidably connected to the guide rod 6. The sliding limit between the guide rod 6 and the guide holes 51 can limit the sliding of the fastening block 4 and each movable block 5, thereby improving the sliding accuracy of the fastening block 4 and each movable block 5.

[0042] It should be understood that when the guide rod 6 is a non-cylindrical structure, only one guide rod 6 is required to achieve the left and right sliding limit of the fastening block 4 and each moving block 5; however, when the guide rod 6 is a cylindrical structure, at least two guide rods 6 are required to achieve the left and right sliding limit of the fastening block 4 and each moving block 5.

[0043] The present application does not limit the installation method of the guide rod 6. The following only provides a specific installation method for reference: Figure 2 and Figure 3 As shown, the base 1 is provided with a support block 11, and the support block 11 and the fixing block 3 are both provided with a bolt hole 31 and a mounting hole 32 for adapting to the guide rod 6. The inner wall of the mounting hole 32 is penetrated outwardly by an open slit 33; the multifunctional flat-nose pliers also include a fastening bolt 10, which is threadedly connected to the bolt hole 31, thereby reducing the gap in the open slit 33, thereby allowing the mounting hole 32 to clamp the guide rod 6. Before installing the fastening bolt 10, the presence of the open slit 33 facilitates the insertion of the end of the guide rod 6 into the mounting hole 32; after installing the fastening bolt 10, the gap in the open slit 33 is reduced, thereby allowing the mounting hole 32 to fully clamp the guide rod 6, thereby achieving the installation and fixation of the guide rod 6.

[0044] This application does not limit the specific structure of the driving member 2. The following only provides a specific structure for reference: Figure 2 、 Figure 3 and Figure 4As shown, the driving member 2 includes a screw rod 21, the left end of the screw rod 21 is rotatably connected to the fixed block 3, and the right end of the screw rod 21 is rotatably connected to the base 1; the fastening block 4 is provided with threaded holes 41 for threaded connection of the screw rod 21, and each movable block 5 is provided with a clearance hole 53 for the screw rod 21 to pass through. By driving the screw rod 21 to rotate, the screw rod 21 is able to drive the fastening block 4 to slide left and right through the threaded hole 41. In addition, the screw rod 21 does not take up extra space and can provide a sufficiently long driving stroke; moreover, when the screw rod 21 stops rotating, it can achieve self-locking, with a simple structure, easy use and high stability. It should be noted that the shape and size of the clearance hole 53 on the movable block 5 should be based on not interfering with other structures and their installation. Specifically, when the movable block 5 is an integral structure, the clearance hole 53 on the movable block 5 can be a circular structure (such as Figure 2 As shown), the inner diameter of the clearance hole 53 should be greater than or equal to the outer diameter of the screw rod 21; when the moving block 5 is divided into multiple module units 50, the shape of the clearance hole 53 should not affect the installation of the module unit 50, that is, it should not affect the insertion of the guide rod 6 into the guide hole 51 through the notch 52.

[0045] The present application does not limit the rotatable installation method of the screw rod 21. The following only provides a specific rotatable installation method for reference: Figure 4 、 Figure 5 and Figure 6 As shown, the driving member 2 also includes a first gasket 22, a second gasket 23 and a mounting bolt 24; a rotating portion 211 is provided at one end of the screw rod 21, and the other end of the screw rod 21 passes through the axial hole 34 on the fixing block 3 and the axial hole 34 on the fastening block 4, so that the screw rod 21 can rotate in the axial hole 34; the first gasket 22 is provided between the rotating portion 211 and the fixing block 3, and the mounting bolt 24 passes through the second gasket 23 and is threadedly connected to the end of the screw rod 21 away from the rotating portion 211, thereby limiting the axial displacement of the screw rod 21.

[0046] In some embodiments of the present application, the multifunctional flat-nose pliers further include a bottom plate 8, and the base 1 is detachably mounted on the bottom plate 8. By mounting the bottom plate 8 on a processing station and detachably connecting the base 1 and the bottom plate 8, the base 1 can be mounted, fixed, or removed, thereby facilitating disassembly, assembly, and replacement.

[0047] This application does not limit the detachable installation method between the bottom plate 8 and the base 1. The following only provides a specific detachable installation method for reference: Figure 2 and Figure 4 As shown, the bottom plate 8 and the base 1 are positioned by the positioning pins 9 and then locked by bolts.

[0048] Reference Figure 1In some embodiments of the present application, the fastening block 4 and each movable block 5 are provided with fixing holes 54 for installing special clamping tools. The fixing holes 54 can be used to install special clamping tools, thereby clamping a wider variety of workpieces, which is suitable for enterprises with a large variety of workpieces and large quantities.

[0049] Example 2: Different from Example 1, Figures 7 to 10 As shown, the movable block 5 is divided into at least two module units 50 along the left and right directions, and the inner wall of the guide hole 51 on each module unit 50 is penetrated outwardly with a notch 52, and the notch 52 is used to pass the guide rod 6, and the opening directions of the two adjacent notches 52 on the left and right are staggered with each other; the multifunctional flat-nose pliers also include a locking piece 7, which is used to lock each module unit 50. On the one hand, when it is necessary to add or reduce the moving block 5, it is only necessary to align the notch 52 on the module unit 50 with the guide rod 6, so that the guide rod 6 can be directly inserted into the corresponding guide hole 51, or directly removed from the corresponding guide hole 51, that is, there is no need to first remove the guide rod 6, the fixing block 3 (or the fastening block 4) and the screw rod 21 (when the driving member 2 is the screw rod 21), thereby making the operation of adding or reducing the moving block 5 simpler; and, since the opening directions of the two adjacent notches 52 on the left and right are staggered, when each module unit 50 is locked by the locking member 7, the staggered arrangement of the notches 52 can just limit the guide rod 6 from escaping from the guide hole 51 from the notch 52. On the other hand, when it is necessary to adjust the spacing between two adjacent clamping areas, the purpose of adjusting the spacing between two adjacent clamping areas can be achieved by increasing or decreasing the total number of module units 50 corresponding to the same moving block 5 or replacing the thickness (i.e., the size in the left and right direction) of a single (or multiple) module unit 50.

[0050] Reference Figures 8 to 10In some embodiments of the present application, the opening directions of the notches 52 on the same module unit 50 are the same, and the opening directions of two adjacent notches 52 are staggered in the vertical direction. For a module unit 50 with the notch 52 opening downward, it can be directly inserted downward from above the guide rod 6 or directly removed upward; for a module unit 50 with the notch 52 opening upward, it can be directly inserted upward from below the guide rod 6 or directly removed downward. Since, under the action of gravity, the tight fitting surface between the guide rod 6 and the guide hole 51 (i.e., the position prone to wear) is located on the upper side of the guide hole 51, the thickness of the module unit 50 with the opening direction of the notch 52 facing downward can be increased, and the thickness of the module unit 50 with the opening direction of the notch 52 facing upward can be reduced. Therefore, in the case of the moving block 5 of the same width, the contact area of ​​the tight fitting surface between the guide rod 6 and the guide hole 51 is effectively increased, thereby delaying the wear of the guide rod 6 and the guide hole 51; in addition, when the distance between the guide rod 6 and the base 1 is small, the smaller the thickness of the module unit 50 with the opening direction of the notch 52 facing upward, the easier it is to install the module unit 50 from the gap between the guide rod 6 and the base 1, that is, the module unit 50 is first inserted into the gap between the guide rod 6 and the base 1 in a flat posture, and then rotated 90° to achieve installation (such as Figure 10 To disassemble, just follow the reverse operation.

[0051] Reference Figures 8 to 10 In some embodiments of the present application, the same moving block 5 is divided into at least three modular units 50, namely a left module 501, a right module 503, and at least one intermediate module 502. In this layout, the intermediate modules 502 can be made into standard parts of different thicknesses or the same thickness, so that the number of intermediate modules 502 can be increased or decreased as needed, thereby changing the width of the moving block 5.

[0052] Reference Figure 9 as well as Figure 11 In some embodiments of the present application, the locking member 7 is a locking bolt. Each modular unit 50 on the same movable block 5 is locked together by at least one locking bolt, with both ends of the locking bolt concealed within the modular unit 50. The locking bolt facilitates locking of the modular units 50, thereby allowing the modular units 50 to be assembled to form the movable block 5. Furthermore, both ends of the locking bolt are concealed within the modular unit 50, preventing interference with other structures.

[0053] Example 3: Reference Figures 12 to 19Unlike the second embodiment, the guide rod 6 is cylindrical, with two guide rods 6 spaced apart in the front-to-back direction. The two notches 52 on the same module unit 50 are both located on the underside of the module unit 50. The opening directions of the two notches 52 on the same module unit 50 are staggered. When one guide rod 6 enters the corresponding guide hole 51 through one notch 52, the module unit 50 can be rotated, allowing the other guide rod 6 to enter the corresponding guide hole 51 through the other notch 52. The cylindrical guide rod 6 and the corresponding circular guide hole 51 are easy to manufacture and have high precision. Furthermore, this arrangement of notches 52 does not affect the installation of the module unit 50, while ensuring that the upper side of the guide hole 51 on each module unit 50 contacts the guide rod 6. This effectively increases the total contact area between the guide hole 51 and the guide rod 6, further slowing wear on the guide rod 6 and the guide hole 51. In addition, since the notch 52 is located on the lower side of the module unit 50, the debris generated during the processing will not accumulate in the notch 52, thereby not affecting the sliding between the guide rod 6 and the guide hole 51; the debris generated during the processing will not accumulate in the clearance hole 53, thereby not affecting the rotation of the screw rod 21.

[0054] The installation principle of each module unit 50 in the third embodiment: When installing, take two module units 50 as an example; Figure 17 As shown, first, the guide rod 6 on the front side is inserted into the corresponding guide hole 51 through the notch 52 on the front side of a module unit 50, and then the module unit 50 is rotated clockwise to insert the guide rod 6 on the rear side into the corresponding guide hole 51 through the notch 52 on the rear side. In this process, the corresponding clearance hole 53 can avoid interference with the screw rod 21. Similarly, Figure 16 and Figure 18 As shown, an adjacent module unit 50 is installed; after the installation is completed, it can be locked by the locking member 7. At this time, as shown in FIG. Figure 19 As shown, since the opening directions of the two adjacent notches 52 are also staggered, when locked by the locking member 7, the two module units 50 cannot be removed from the guide rod 6. When disassembling, only the reverse operation is required.

[0055] The above describes the basic principles, main features, and advantages of the present application.
