Description

Technical Field

[0001] This utility model relates to the field of fixtures and tooling, specifically to a connecting block fixture. Background Technology

[0002] Connecting blocks are mechanical components used to connect and fix different parts, and are widely used in machinery, electronics, and construction. Many plug-in connecting blocks are also found in material handling machines. These connecting blocks are generally rectangular, and to ensure precision, their front and back sides need to be highly parallel. Two through holes are then machined for connecting the material handling machine's plug-in structure. During rough machining, the central positioning hole and the parallelism of the edges are also machined. Summary of the Invention

[0003] This utility model is a connecting block tooling fixture designed to address the problem that the original clamping method is prone to excessive clamping force, which can maintain the parallelism requirement on the fixture, but causes deformation on both the front and back when removing it from the fixture.

[0004] The connecting block tooling fixture has several sets of fixtures arranged in parallel on the tooling platform; each fixture set includes a leveling station and a drilling station; a center positioning plate is set between the leveling station and the drilling station;

[0005] A coarse vertical positioning seat and a first auxiliary positioning cylinder are sequentially arranged on one side of the central positioning plate, and a hollow support block, a horizontal positioning seat, a hollow support block and an elastic auxiliary positioning block are sequentially arranged on the other side.

[0006] A fixing mechanism is provided on the side of the coarse vertical positioning seat, and the drive cylinder of the fixing mechanism is located below the tooling platform.

[0007] A U-shaped clamping mechanism is provided on the side of the horizontal positioning seat. The U-shaped clamping mechanism includes a clamping cover and a lever cylinder. The clamping cover is connected to the lever end of the lever cylinder. A pre-drilled through hole is provided on the clamping cover in the area corresponding to the hollow support block. The cylinder body of the lever cylinder is set perpendicular to the tooling platform.

[0008] The coarse vertical positioning seat includes a front positioning post, a middle positioning platform, and a rear positioning post forming a leveling station; a second through hole is provided on the rear positioning post, which is used to fix the telescopic end positioning of the mechanism.

[0009] The middle positioning platform has protrusions at both ends;

[0010] An extension rod is provided on the telescopic end of the first auxiliary positioning cylinder.

[0011] Fixed mechanisms include:

[0012] The vertical slide rail has a trapezoidal block as its slider, which is set on the tooling platform. The trapezoidal surface is aligned with the coarse vertical positioning seat. A fixing mechanism drive cylinder is set on the bottom surface of the trapezoidal block, and the telescopic end of the fixing mechanism drive cylinder is fixedly connected to the trapezoidal block.

[0013] A positioning groove is provided on the inclined surface of the trapezoidal block;

[0014] A movable positioning rod is provided between the coarse vertical positioning seat and the trapezoidal block. A return spring is sleeved on the movable positioning rod. The movable positioning rod slides with the coarse vertical positioning seat and slides with the positioning groove.

[0015] The positioning method of the leveling station is as follows: First, the workpiece is placed on the coarse vertical positioning seat. Then, the first auxiliary positioning cylinder extends to abut the end of the workpiece against the edge of the center positioning plate to determine the left and right positions. Then, the movable positioning rod is fixed on the workpiece plate surface under the drive of the trapezoidal block inclined surface to fix the workpiece.

[0016] By using trapezoidal blocks to set the telescopic cylinder, which should be placed horizontally, to a vertical position, it is possible to set up more sets of fixtures on the tooling platform with the same space.

[0017] Meanwhile, the horizontal widths of the front and rear positioning posts are the same, both smaller than the width of the middle positioning table, which is beneficial for the flat processing of the workpiece.

[0018] The components of the middle positioning platform and the front side limiting plate are made from the same part, which facilitates production.

[0019] A horizontal positioning seat includes: a base platform, a front side limiting plate provided on the front side of the base platform, and an elastic rod provided on the base platform, the top of the elastic rod being spherical;

[0020] The front side limiting plate appears as a U-shaped block when viewed from above;

[0021] The elastic auxiliary positioning block includes: a third base and a third movable block. A spring is installed inside the third movable block. The third movable block is set on the third base and is positioned by a connecting rod.

[0022] The surface of the third movable block adjacent to the horizontal positioning seat is inclined.

[0023] The clamp is in the shape of a trapezoidal block, and the pre-drilled through holes are set on the inclined surface. The central axis of the pre-drilled through holes is parallel to the bottom surface of the clamp. A pre-reserved groove is also set on the inclined surface, and the pre-reserved groove is set between two pre-drilled through holes.

[0024] The positioning method of the drilling station is as follows: A central hole is pre-drilled in the workpiece during rough machining. When the hollow part is fitted onto the elastic rod, the elastic rod pushes the entire workpiece towards the front side limiting plate, thus aligning it on one side. Simultaneously, the third movable block of the elastic auxiliary positioning block pushes the workpiece towards the center positioning plate, thus aligning it on the second side and determining its position. Then, the lever cylinder drives the clamping cover to press down and fix the workpiece.

[0025] The advantages of this invention are: it allows for the placement of more fixture sets within a limited space, improving space utilization. The cooperation between the coarse vertical positioning seat and the fixing mechanism ensures that the parallelism of the front and rear surfaces after clamping and processing at the leveling station is higher than in the original design. The U-shaped clamping cover mechanism ensures that the hole axis is parallel to the plane during drilling. Attached Figure Description

[0042] The positioning method of the leveling station is as follows: First, the workpiece is placed on the coarse vertical positioning seat. Then, the first auxiliary positioning cylinder 2 extends to abut the end of the workpiece against the edge of the center positioning plate 4 to determine the left and right positions. Then, the movable positioning rod is fixed on the workpiece plate surface under the drive of the trapezoidal block inclined surface to fix the workpiece.

[0043] By using trapezoidal blocks to set the telescopic cylinder, which should be placed horizontally, to a vertical position, it is possible to set up more sets of fixtures on the tooling platform 1 with the same space.

[0044] Meanwhile, the horizontal widths of the front and rear positioning posts are the same, both smaller than the width of the middle positioning table, which is beneficial for the flat processing of the workpiece.

[0051] The positioning method of the drilling station is as follows: A central hole is pre-drilled in the workpiece during rough machining.

At the same time, the third movable block of the elastic auxiliary positioning block pushes the workpiece towards the center positioning plate 4, thereby aligning it on the second side and determining its position. Then, the lever cylinder drives the clamping cover to press down and fix the workpiece.
