Description

Technical Field

[0001] This utility model relates to the field of hydraulic press technology, and in particular to a hydraulic press for positioning workpieces. Background Technology

[0002] Hydraulic presses are devices that convert hydraulic energy into mechanical energy. They use hydraulic cylinders to drive slide blocks to perform pressing, stamping, and other processing. They are widely used in metal forming, assembly, and other fields, and are characterized by high pressure and stable operation.

[0003] Workpiece positioning is crucial for ensuring machining accuracy. Manual positioning is prone to workpiece displacement due to operational errors, and the presence of hands near the mold can easily cause squeezing or shearing accidents, posing a high safety hazard and reducing production efficiency. Traditional hydraulic presses mostly rely on manual positioning and do not have additional positioning structures to assist in the pre-processing positioning of the workpiece.

[0004] Based on this, a hydraulic press for positioning workpieces is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a hydraulic press for positioning workpieces in order to solve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A hydraulic press for positioning workpieces includes a base, a worktable connected to the upper end of the base, a sliding column connected to the upper end of the worktable, a top platform connected to the upper end of the sliding column, a hydraulic cylinder connected to the top platform, a pressure plate connected to the output end of the hydraulic cylinder, a clamping rod slidably connected to one side of the base, a positioning clamp connected to one end of the clamping rod, and a transmission mechanism connected to one side of the positioning clamp for positioning the workpiece.

[0008] Preferably, a bending block is connected to one side of the workbench, and the clamping rod is slidably connected to the bending block.

[0009] Preferably, the transmission mechanism includes a traction bar, one end of which is rotatably connected to a bending block, and the other end of which is rotatably connected to a connecting frame. The connecting frame is rotatably connected to one side of a pressure plate. One end of the clamping rod is connected to an abutment bar, and a spring is connected between the abutment bar and the bending block.

[0010] Preferably, a rotating seat is connected to the bending block, and one end of the traction bar is rotatably connected to the rotating seat.

[0011] Preferably, a connecting strip is connected to one side of the pressure plate, and the connecting frame is rotatably connected to the connecting strip.

[0012] Preferably, a roller is rotatably connected to the abutment strip.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0014] 1. This application adopts a positioning clamp structure to clamp and position the workpiece, thereby improving the workpiece's machining accuracy and reducing machining safety hazards. By setting a spring structure, the positioning clamp can be retracted during machining to avoid interfering with the pressure plate's machining operations.

[0015] 2. This application adopts a traction bar structure, in which the traction bar deflects under the action of the connecting frame, thereby pressing the abutment bar and causing the positioning clamp to move toward the workpiece on the worktable, thereby clamping and positioning the workpiece automatically, improving processing accuracy and efficiency.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-3 This utility model provides a technical solution:

[0023] A hydraulic press for positioning workpieces includes a base 1, a worktable 2 connected to the upper end of the base 1, a sliding column 3 connected to the upper end of the worktable 2, a top platform 4 connected to the upper end of the sliding column 3, and a hydraulic cylinder 5 connected to the top platform 4. The hydraulic cylinder 5 can drive a pressure plate 6 to move up and down. The hydraulic cylinder 5 is a direct reference to the prior art. The output end of the hydraulic cylinder 5 is connected to the pressure plate 6. A clamping rod 11 is slidably connected to one side of the base 1. One end of the clamping rod 11 is connected to a positioning clamp 10. The structure of the positioning clamp 10 is adapted to the workpiece to ensure that the positioning clamp 10 can stably position the workpiece. A transmission mechanism for driving the positioning clamp 10 to position the workpiece is connected to one side of the positioning clamp 10.

[0024] Specifically, such as Figure 3 As shown, a bending block 7 is connected to one side of the workbench 2, and a clamping rod 11 is slidably connected to the bending block 7. Two clamping rods 11 are symmetrically connected to a single bending block 7, thereby ensuring that the positioning clamp 10 can move horizontally stably.

[0025] Specifically, such as Figure 2 and Figure 3 As shown, the transmission mechanism includes a traction bar 9, one end of which is rotatably connected to the bending block 7. By deflecting the traction bar 9, the abutment bar 12 located on one side of the traction bar 9 can be pushed to move. The other end of the traction bar 9 is rotatably connected to a connecting frame 8, which is rotatably connected to one side of the pressure plate 6. When the pressure plate 6 moves up and down, it can synchronously drive one end of the connecting frame 8 to move. One end of the clamping rod 11 is connected to the abutment bar 12. A spring 13 is connected between the abutment bar 12 and the bending block 7. By setting the spring 13, the abutment bar 12 can automatically reset, that is, when the abutment bar 12 is not subjected to external force, the abutment bar 12 can move away from the worktable 2.

[0026] Specifically, such as Figure 3 As shown, a rotating seat 14 is connected to the bending block 7, and one end of the traction bar 9 is rotatably connected to the rotating seat 14. The rotating seat 14 is located below the clamping rod 11.

[0027] Specifically, such as Figure 3 As shown, a connecting strip 15 is connected to one side of the pressure plate 6, and the connecting frame 8 is rotatably connected to the connecting strip 15. The pressure plate 6 can drive the connecting strip 15 to rise and fall synchronously.

[0028] Specifically, such as Figure 3 As shown, a roller 16 is rotatably connected to the abutment bar 12. By setting the roller 16, the structural wear caused by the traction bar 9 pushing the abutment bar 12 can be effectively reduced, and the transmission stability can be improved.

[0029] In summary, the hydraulic press for positioning workpieces provided in this embodiment allows the operator to place the workpiece on the worktable 2 when workpiece processing is required, without manually positioning the workpiece. Then, the hydraulic cylinder 5 is activated, which drives the pressure plate 6 to rise and then fall. When the pressure plate 6 rises, it pulls the connecting frame 8, causing the traction bar 9 to deflect upward. At this time, the traction bar 9 abuts against the roller 16, thereby pushing the clamping rod 11 to move towards the center position of the worktable 2. At this time, the spring 13 structure is further stretched, which simultaneously drives the positioning clamp 10 to position and clamp the workpiece, thereby accurately positioning the workpiece before processing.

[0030] Subsequently, the height of the pressure plate 6 decreases, at which point the traction bar 9 deflects downwards, and the spring 13 structure pulls the positioning clamps 10 away from each other until the positioning clamps 10 are stored on the bending block 7. At this time, the positioning clamps 10 will not interfere with the operation of the pressure plate 6. When the pressure plate 6 contacts the workpiece, the workpiece is processed.

[0031] This hydraulic press can automatically position the workpiece before processing, improving the processing accuracy and reducing operational safety hazards.

[0032] The above description of the embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
