Description

Technical Field

[0001] This utility model belongs to the field of pneumatic technology, and in particular relates to a pneumatic crimping tool with a pressing structure. Background Technology

[0002] Pneumatic crimping fixtures are crimping tools that use compressed air as a power source and are driven by pneumatic components (such as cylinders and valves). They are mainly used for crimping metal pipes, wires, cables and other connectors. By applying a certain pressure, the connectors are tightly connected, thereby achieving the purpose of fixing.

[0003] Pneumatic crimping fixtures mainly consist of an air source, an air circuit control system, a pneumatic actuator, and a crimping die. Simply put, the air source provides compressed air and delivers it to the fixture through pipelines; the air circuit control system is used to control the flow of air, regulate pressure, and lubricate; the pneumatic actuator is usually a cylinder that uses compressed air to drive a piston to move, producing linear or rotary motion; the crimping die is used to directly apply pressure to the connecting parts.

[0004] During the crimping process, the clamping structure must ensure that the parts being crimped maintain the correct position and posture to guarantee the accuracy and consistency of the crimping and avoid substandard crimping quality due to positional deviations. However, the parts being crimped may be displaced or deformed due to pressure, or even accidentally pop out or move, posing a threat to the safety of the operator. Therefore, a pneumatic crimping tool with a clamping structure is needed to solve the above problems. Utility Model Content

[0017] This utility model features a clamping structure comprising a mounting frame, a clamping plate, connecting columns, and return springs. The mounting frame is positioned on a worktable and has a pair of mounting holes. A pair of connecting columns are slidably inserted into the mounting holes, and a pair of return springs are inserted into the connecting columns.

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0025] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0026] like Figures 1 to 3 As shown, this utility model embodiment provides a pneumatic crimping tool with a pressing structure, including:

[0027] Workbench 1;

[0028] Pressing structure 2 is installed on workbench 1;

[0029] The clamping structure 3 includes a mounting frame 31, a clamping plate 32, a connecting column 33, and a return spring 34. The mounting frame 31 is disposed on the workbench 1 and has a pair of mounting holes 311. A pair of connecting columns 33 and a pair of return springs 34 are provided. The pair of connecting columns 33 are slidably inserted into the pair of mounting holes 311, and the pair of return springs 34 are inserted into the pair of connecting columns 33. The two ends of the return springs 34 are connected to the mounting frame 31 and the connecting columns 33. The clamping plate 32 is fixedly installed on the lower end of the connecting column 33.

[0030] Specifically, the clamping structure 3 also includes a limiting plate 35, which is fixedly installed on the upper end of the connecting column 33, and the two ends of the return spring 34 are connected to the lower end face of the limiting plate 35 and the mounting bracket 31.

[0031] In this embodiment, after the workpiece is abutted and fixed by the limiting block 221, the mounting frame 31 slides until the clamping plate 32 placed on the upper surface of the mounting frame 31 is directly above the workpiece; during the movement of the mounting frame 31, the worker pulls the limiting plate 35 so that the lower end surface of the clamping plate 32 is separated from the workpiece. After the movement, the limiting plate 35 is released so that the lower end surface of the clamping plate 32 is in contact with the workpiece. In this way, the workpiece is prevented from being displaced or deformed due to pressure, or even accidentally popped out or moved, thus ensuring the safety of the operator.

[0032] Specifically, the workbench 1 has a pair of parallel sliding grooves 11, the clamping structure 3 also includes screws 36, the lower end of the mounting bracket 31 is slidably placed in the sliding groove 11, a pair of screws 36 are provided, the pair of screws 36 are rotatably installed in the pair of sliding grooves 11 respectively, and the screws 36 are threadedly connected to the lower end of the mounting bracket 31.

[0033] Specifically, the clamping structure 3 also includes pulleys 37 and a drive belt 38. A pair of pulleys 37 are provided, and the drive belt 38 is connected to the pair of pulleys 37. The pair of pulleys 37 are respectively connected to one end of the screw 36.

[0034] In this embodiment, after the workpiece is abutted and fixed by the limiting block 221, the worker rotates one of the pulleys 37, and through the transmission belt 38, the other pulley 37 also rotates, thereby driving a pair of screws 36 connected to the pulleys 37 to rotate synchronously around their own axis, so that the mounting frame 31 slides in the slide groove 11 until the clamping plate 32 placed on the upper end face of the mounting frame 31 is placed directly above the workpiece.

[0035] Specifically, the pressing structure 2 includes a rotating screw 21, a limiting member 22, a sliding member 23, and a pressing member 24. The rotating screw 21 is rotatably mounted on the worktable 1, the sliding member 23 is mounted on the worktable 1, the limiting member 22 is slidably disposed on the sliding member 23, the rotating screw 21 is threadedly connected to the limiting member 22, and the pressing member 24 is fixedly mounted on the worktable 1.

[0036] In this embodiment, the worker places the workpiece to be crimped on the workbench 1 and close it to the crimping part 24, and then rotates the rotating screw 21, thereby driving the limiting block 221, which is threadedly connected to the rotating screw 21, to slide along the slide bar 23 axially until one end face of the limiting block 221 abuts and fixes the side of the workpiece.

[0037] Specifically, the limiting component 22 includes a limiting block 221 and a cylinder 222. The limiting block 221 is slidably disposed on the slide rod 23. The limiting block 221 is threadedly connected to the rotating screw 21. The cylinder 222 is installed on the limiting block 221.

[0038] The working principle of this utility model is as follows:

[0039] First, the worker places the workpiece to be crimped on the workbench 1 and close it to the crimping part 24. Then, the worker rotates the rotating screw 21, which in turn drives the limiting block 221, which is threadedly connected to the rotating screw 21, to slide along the slide bar 23 axially until one end face of the limiting block 221 abuts and fixes the side of the workpiece.

[0040] In other embodiments, after activation, the cylinder 222 drives the limiting block 221 to slide axially along the slide bar 23 until one end face of the limiting block 221 abuts and fixes the side of the workpiece.

[0041] After the workpiece is abutted and fixed by the limiting block 221, the worker rotates one of the pulleys 37. Through the transmission belt 38, the other pulley 37 also rotates, which in turn drives a pair of screws 36 connected to the pulleys 37 to rotate synchronously around their own axis, so that the mounting bracket 31 slides in the slide groove 11 until the clamping plate 32 placed on the upper end face of the mounting bracket 31 is placed directly above the workpiece.

[0042] During the movement of the mounting bracket 31, the worker pulls the limiting plate 35 to disengage the lower end face of the clamping plate 32 from the workpiece. After the movement, the limiting plate 35 is released so that the lower end face of the clamping plate 32 is in contact with the workpiece. This prevents the workpiece from being displaced or deformed due to pressure, or even from accidentally popping out or moving, thus ensuring the safety of the operator.

[0043] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
