Description

Technical Field

[0001] The utility model relates to the technical field of bending machines, and particularly relates to a horizontal double-slide post-positioning mechanism. Background Art

[0002] In traditional post-positioning structures of bending machines, the upper crossbeam (cast aluminum / steel square pipe) is generally used as the fixed support body for the stop fingers. For the entire post-positioning moving mechanism, it appears to be relatively bulky. For example, CN205217823U discloses a post-positioning mechanism, including a cast aluminum slide assembly, a first lifting mechanism, a second lifting mechanism, a crossbeam assembly and other structural parts. This structure has problems such as weak bottom support ability and insufficient stability.

[0003] Due to the heavy overall structure and large moment of inertia of the post-positioning crossbeam mechanism in the prior art, the overall stability decreases during high-speed movement, so there are limitations on its speed. And the post-positioning crossbeam mechanism is generally integrated, and the stop fingers on both left and right sides can only move forward or backward simultaneously, and cannot be controlled to move forward and backward according to actual processing requirements. Summary of the Utility Model

[0009] Further, a photoelectric sensor is also provided at one end of the first linear slide rail group.

[0010] Further, the horizontal guide rail module includes a fixed seat, a guide rail member, a gear rack, and a second drive assembly; the guide rail member is arranged above the fixed seat, and the gear rack is arranged on both sides of the fixed seat; the horizontal slide module is arranged above the guide rail member; the second drive assembly includes a second motor, a speed reducer, a rear positioning motor fixed seat, and a cylindrical helical gear connected in sequence; a rear positioning stop block and left and right limit blocks are provided below the rear positioning motor fixed seat; a motor seat fixing plate is provided above, and the rear positioning motor fixed seat is connected to the horizontal slide module through the motor seat fixing plate; one end of the speed reducer is connected to the second motor, and the other end passes through the rear positioning motor fixed seat and is fixed to the cylindrical helical gear; the cylindrical helical gear meshes with the gear rack; by driving the cylindrical helical gear to rotate through the second motor, the horizontal slide module is realized to move horizontally along the guide rail member.

[0011] Further, the horizontal lifting module includes a fixed bracket, a third drive assembly, a second lead screw assembly, a second linear module, and a top plate; the bottom of the second lead screw assembly is suspended, the top is fixed to the top plate, and the side is connected to the second linear module; the positioning stop finger is arranged on the top plate; the second linear module is installed on the inner walls of both sides of the fixed bracket; by driving the second lead screw assembly to rotate through the third drive assembly, the second lead screw assembly drives the top plate to move up and down along the direction of the second linear module.

[0014] Further, the positioning stop finger is a three-section positioning stop finger.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] (1) Compared with the traditional one: In the traditional bending machine rear positioning structure, the upper crossbeam (cast aluminum / steel square pipe) is generally used as the fixed support body for the stop finger. For the entire rear positioning moving mechanism, it appears relatively bulky. However, in this horizontal double-slide table rear positioning mechanism, the upper crossbeam is cancelled, and the overall mechanism is relatively more compact and flexible.

[0017] (2) The horizontal slide table module of the present utility model can move at high speed: Compared with the traditional one, due to the relatively heavy overall structure and large moving inertia of the rear positioning crossbeam mechanism, the overall stability decreases during high-speed movement, so its speed has limited requirements. However, the horizontal double-slide table rear positioning mechanism is independently and separately controlled, with a small moving mechanism inertia, and has no impact on the stability performance of the mechanism under high-speed movement.

[0018] (3) Independent controllability of the mechanism: Compared with the traditional one, the rear positioning mechanism of the crossbeam is integrated, and the left and right positioning stop fingers can only move forward or backward simultaneously, and cannot be controlled to move forward and backward according to actual processing requirements. However, the horizontal rear positioning mechanism can well solve this requirement, and can move separately and independently on the left and right to meet the processing requirements of different products and improve efficiency.

[0019] (4) Improve the installation and debugging efficiency: This horizontal type can be independently controlled to move forward and backward, and the front and rear error dimensions of the stop finger can be finely adjusted and repaired through system parameters, which is beneficial to shortening the micro-precision debugging time and improving the production assembly and debugging efficiency.

[0020] In summary, the horizontal double-slide table rear positioning mechanism of the present utility model mainly consists of Z1 and Z2 axes (left and right movement), X1 and X2 axes (front and back movement), and R1 and R2 axes (lifting movement). The separate and independent control is because the two groups of horizontal slide table modules are an independent integral mechanism, and the two groups of horizontal slide table modules can respectively perform left and right, front and back, and lifting movements, and there is no interference between the actions of the two groups of horizontal slide table modules.
