Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of clamps, in particular to a quickly replaceable modular clamping clamp for a forklift. Background Art
[0002] Forklifts, an indispensable handling tool in the logistics and warehousing industries, are widely used in various working environments due to their powerful functionality and flexibility. In the production of forklifts, the forklift frame is undoubtedly an indispensable core part of the entire forklift system. It is not only a solid foundation for the forklift to carry and transport goods, but also the key to ensure the efficient, stable and safe operation of the forklift.
[0003] In modern industrial production, the production of large-tonnage forklift frames faces a significant challenge: a wide variety of products with large structural differences. This diversity not only requires a high degree of flexibility in the production process, but also places extremely high demands on the adaptability of the clamping fixture. As a bridge connecting the workpiece and the processing equipment, the rationality of the design of the clamping fixture directly affects the efficiency and accuracy of production.
[0004] However, the traditional fixture designs currently used in many factories are often limited to the same series of products. When the product changes, the adaptability of the fixture becomes stretched. This limitation is mainly reflected in two aspects: first, the blocking area of the fixture is large, which may hinder certain processing surfaces of the workpiece, resulting in incomplete processing or requiring additional operations; second, the modularity of the fixture is low. When the product is changed, more parts of the fixture need to be replaced, which not only increases the difficulty of operation, but also greatly prolongs the mold change time, seriously affecting production efficiency.
[0005] In view of this, we propose a quickly replaceable modular clamping fixture for forklifts. Utility Model Content
[0006] The purpose of the utility model is to provide a quickly replaceable modular clamping fixture for forklifts which can improve concentricity and facilitate parts assembly, so as to solve the problems raised in the above-mentioned background technology.

The transverse movement mechanism drives the clamping structure to move synchronously. The clamping structure includes a mounting plate and a fixing member. The fixing member is used to fix a vehicle frame. The fixing member is fixed to the mounting plate by a locating pin.
[0009] As a further solution of the utility model: the fixing member includes a fixing plate, and both the fixing plate and the mounting plate are provided with mounting holes for inserting the positioning pins.
[0010] As a further solution of the utility model: the transverse movement mechanism includes a shell, an adjustment structure is arranged in the shell, the adjustment structure includes a first screw rod and a second screw rod, a coupling is arranged between the first screw rod and the second screw rod, and a rotating part is fixed to one end of the second screw rod away from the coupling.

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0029] Embodiment 1
[0030] like Figure 1 As shown, this embodiment provides a quickly replaceable modular clamping fixture for forklifts. Considering the clamping operation of the vehicle frame, the device includes a transverse mechanism 100 and a clamping structure 200. There are two clamping structures 200, which are equidistantly installed at the center of the transverse mechanism 100. The transverse mechanism 100 drives the clamping structure 200 to move synchronously. The clamping structure 200 includes a mounting plate 204 and a fixing member 210. The fixing member 210 is used to fix the vehicle frame. The fixing member 210 is fixed to the mounting plate 204 by a positioning pin.
[0031] The improvement of this embodiment lies in that the entire clamping structure 200 is installed by dividing it into a mounting plate 204 module and a fixing member 210 module, and combining it with the precise fixing method of the positioning pin. The overall structure is simple and easy to install. At the same time, the time for subsequent replacement of the fixing member 210 module is shortened, thereby achieving rapid replacement and improving production efficiency. Each fixing member 210 module corresponds to a type of frame. By replacing the mounting plate 204 module, the one-time investment cost of the equipment is reduced and the flexibility of production is improved.
[0032] In order to facilitate the fixing of the positioning pin, the fixing member 210 includes a fixing plate 211. The fixing plate 211 and the mounting plate 204 are both provided with mounting holes 212, and each mounting hole 212 corresponds to each other, so as to facilitate the insertion of the positioning pin and fix the fixing member 210 on the mounting plate 204. In consideration of the stability of the mounting plate 204, a reinforcing plate 205 is symmetrically provided between the mounting plate 204 and the base plate 203, and the reinforcing plate 205 is used to support the mounting plate 204.
[0033] like Figure 2 and Figure 3 As shown, in order to realize the synchronous movement of the two clamping structures 200, the traverse mechanism 100 includes a housing 101, an adjusting structure 110 is arranged in the housing 101, and the adjusting structure 110 includes a first screw rod 111 and a second screw rod 113, a coupling 112 is arranged between the first screw rod 111 and the second screw rod 113, the thread directions of the first screw rod 111 and the second screw rod 113 are opposite, and a rotating member 114 is fixed to one end of the second screw rod 113 away from the coupling 112; a through slot 102 is arranged on one side of the housing 101, and a bottom plate 203 is fixed to one end of the mounting plate 204, and a bottom plate 204 is fixed to one end of the mounting plate 204. A connecting plate 201 is bolted to one side of the plate 203, and a bracket 202 is provided on the side of the connecting plate 201 away from the mounting plate 204. The bracket 202 is threadedly connected to the screw rod. When the rotating member 114 is manually rotated, the rotating member 114 drives the second screw rod 113 to rotate, and then the second screw rod 113 drives the first screw rod 111 to rotate synchronously through the coupling 112. The screw thread rotates, so that the bracket 202 moves in the through groove 102, and the thread directions of the first screw rod 111 and the second screw rod 113 are opposite, forming two clamping structures 200 that move synchronously but in different directions.
[0034] like Figure 4 and Figure 5 As shown, a cylindrical clamping block 213 is provided on one side of the fixing plate 211 away from the mounting plate 204 , and the clamping block 213 is clamped to a clamping interface of the frame for fixing, thereby completing the fixing of the frame with a clamping interface type.
[0035] Embodiment 2
[0036] like Figure 6 and Figure 7 As shown, the difference from the first embodiment is that an arc-shaped limit block 214 is provided on the side of the fixing plate 211 away from the mounting plate 204, and the arc-shaped limit block 214 is used to limit the frame. A plurality of fixing holes 215 are provided on the periphery of the limit block 214, and the fixing holes 215 correspond to the positioning holes of the frame. The positioning holes of the frame and the fixing holes 215 of the fixing plate 211 are fixed by bolts, thereby completing the fixation of the frame with positioning holes, which is the same as the first embodiment.
[0037] In summary, the working principle of this solution is as follows:
[0038] The bottom plate 203 is fixed to one side of the connecting plate 201 by bolts, and a fixing piece 210 adapted to the frame to be fixed is selected. After the mounting hole 212 on the fixing plate 211 is aligned with the mounting hole 212 on one side of the connecting plate 201, a positioning pin is inserted to fix the fixing piece 210 to one side of the connecting plate 201, and the rotating piece 114 is rotated. The rotating piece 114 drives the second screw rod 113 to rotate, and then the second screw rod 113 drives the first screw rod 111 to rotate synchronously through the coupling 112. The screw thread rotates, and the bracket fixed to one side of the connecting plate 201 is fixed. 202 moves in the through slot 102 of the housing 101, thereby driving the two clamping structures 200 to push out and fix the frame. When the fixing part of the frame is a card interface, a fixing piece 210 with a card block 213 is selected, and the card block 213 is carded to the card interface of the frame, thereby completing the fixation of the frame; when the fixing part of the frame is a positioning hole, a fixing piece 210 with a fixing hole 215 is selected. When the fixing part of the frame is against the limit block 214 of the fixing piece 210, the fixing hole 215 coincides with the positioning hole of the frame, and then bolts are used to fix it.
[0039] Although this specification is described according to implementation modes, not every implementation mode includes only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
[0040] Therefore, the above description is only a preferred embodiment of the present application and is not intended to limit the scope of implementation of the present application; that is, all equivalent changes made according to the scope of the claims of the present application are within the protection scope of the claims of the present application.
