Description

Technical Field

[0001] This utility model relates to the field of industrial production tool technology, and in particular to a fixture that can fix different workpieces for processing. Background Technology

[0002] In industrial production, it is often necessary to fix parts before processing, such as for processing commercial display profiles. These workpieces generally vary in length, size, and shape, requiring specialized fixtures for fixation. While specialized fixtures are indeed more convenient and faster for fixing specific workpieces, they are usually more expensive, and once a batch of products is completed and no further production is needed, the fixtures may be discarded, resulting in significant waste. Furthermore, manufacturers typically produce many product models with complex structures, varying profile sizes, and short order cycles. Changing fixtures for each different product not only makes operation more cumbersome and inefficient but also increases the cost of configuring different fixtures. Therefore, although some fixtures with certain general functions have been invented, these fixtures involve numerous parts, are expensive, complex to use, and lack stability. Utility Model Content

[0003] This utility model addresses the shortcomings of existing technologies by providing a general-purpose profile processing fixture with a simpler structure, fewer parts, lower cost, easier operation, higher production efficiency, and better stability, which can be used to fix most profile products.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a general-purpose profile processing fixture, comprising a support frame, characterized in that: a positioning cylinder for positioning along the X-axis direction is installed at at least one end of the support frame; a plurality of fixed blocks movable along the X-axis direction are installed on the support frame; a plurality of push blocks are arranged opposite the fixed blocks, each push block being connected to a pushing cylinder, the pushing cylinder being installed on the support frame; the space between the positioning cylinder, the fixed blocks and the push blocks forms an elongated clamping space for accommodating the product to be processed; a plurality of pressure plates are arranged above the clamping space, each pressure plate being connected to a clamping cylinder, the clamping cylinder being mounted on the support frame with a movable structure.

[0005] Furthermore, elongated mounting holes are provided on the support frame along the longitudinal direction. Each clamping cylinder is installed on the bottom surface of the support frame by bolts passing through the mounting holes and cooperating with the locking block. The pressure plate is connected and fixed to the top of the cylinder rod of the clamping cylinder to be suspended above the clamping space and the fixing block.

[0006] Furthermore, a long strip-shaped mounting groove is provided longitudinally on the support frame, and the bottom of the fixing block is embedded in the mounting groove to form a structure that can be adjusted by moving along the mounting groove.

[0007] Furthermore, the cylinder rod of the push cylinder is connected to a fixed seat, and the end of the fixed seat has a U-shaped groove. The push block is embedded in the U-shaped groove, and the push block is locked to the fixed seat by screwing in a locking screw from the fixed seat.

[0008] Furthermore, a fixed beam is installed on the side of the support frame, and each push cylinder is installed on the fixed beam.

[0009] Furthermore, several vertically extending elongated fixing holes are provided along the side wall of the fixing beam. Fixing screws are screwed into the side of the support frame through the fixing holes to lock and fix the fixing beam to the support frame.

[0010] Furthermore, several screw holes are provided in the mounting slot, and a strip-shaped hole extending in the same direction as the mounting slot is provided on the fixing block. Screws are screwed through the strip-shaped hole into the screw hole to lock the fixing block onto the support frame. Loosening the screws allows the fixing block to be moved, and tightening the screws again when it is in place locks the fixing block in place, thus achieving position adjustment of the fixing block.

[0011] Furthermore, several adjustment holes are provided on the fixed beam. The push cylinder is fixed by screwing in the locking screw after aligning it with different adjustment holes.

[0012] This utility model utilizes the coordinated operation of components such as a pressure plate, a clamping cylinder, a push block, a pushing cylinder, a fixing block, and a positioning cylinder. The movement of these components in all directions allows the machine to adapt to the product being processed, avoiding areas that require machining. This significantly improves clamping efficiency and stably secures the product, ensuring stable processing. It can accommodate products of various models, lengths, sizes, and shapes, achieving multi-purpose functionality and saving costs while avoiding waste. Furthermore, the fixture has a simple structure with few parts, allowing for quick installation and setup, thus improving work efficiency. Attached Figure Description

Detailed Implementation

[0017] In this embodiment, refer to Figures 1-3 The general-purpose profile processing fixture includes a support frame 1. A positioning cylinder 8 for positioning along the X-axis is installed at one end (or both ends) of the support frame 1. Several movable fixing blocks 6 are installed on the support frame 1. Several push blocks 5 are arranged opposite the fixing blocks 6, each push block 5 connected to a pushing cylinder 4, which is mounted on the support frame 1. The space between the positioning cylinder 8, fixing blocks 6, and push blocks 5 forms a long, narrow clamping space for accommodating the product to be processed. Several pressure plates 2 are arranged above this clamping space, each pressure plate 2 connected to a clamping cylinder 3, which is movable and mounted on the support frame 1. After the product to be processed is placed in the clamping space, the positioning cylinder 8 presses against one end of the product to achieve positioning in the X-axis direction. The clamping cylinder 3 drives the pressure plate to achieve positioning in the Z-axis direction, and the pushing cylinder 4 drives the push plate 5 to cooperate with the fixing blocks 6 to achieve positioning in the Y-axis direction.

[0018] A long, narrow mounting hole 11 is provided longitudinally on the support frame 1. Each clamping cylinder 3 is installed on the bottom surface of the support frame 1 by bolts passing through the mounting hole 11 and engaging with the locking block 31. The pressure plate 2 is connected and fixed to the top of the cylinder rod of the clamping cylinder 3 to suspend it above the clamping space and the fixing block 6. When the position of the pressure plate 2 is not suitable, the bolts can be loosened, the clamping cylinder 3 can be moved until the pressure plate 2 is in the appropriate position, and then the bolts can be tightened to lock the clamping cylinder 3, thus achieving a quick adjustment of the position of the pressure plate 2.

[0019] A long, narrow mounting groove 12 is provided longitudinally on the support frame 1.

The fixing beam 7 and the support frame 1 are locked and fixed by screwing the fixing screws 9 through the fixing holes 71 and screwing them into the side of the support frame 1. After loosening the fixing screws 9, the fixing beam 7 can be moved up and down and then the fixing screws 9 can be tightened. This allows for adjustment of the high position of the push cylinder 4 to accommodate products of different heights.

[0023] Several screw holes are provided in the mounting slot 12, and a strip-shaped hole 61 extending in the same direction as the mounting slot 12 is provided on the fixing block 6. The fixing block 6 is locked onto the support frame 1 by screwing screws through the strip-shaped hole 61 and screwing them into the screw holes. The fixing block 6 can be moved by loosening the screws, and the fixing block 6 can be locked by tightening the screws again after it is moved into place. This allows the position of the fixing block 6 to be adjusted, and fixing blocks 6 of different heights can be quickly replaced according to the product height.

[0024] Several adjustment holes 72 are provided on the fixed beam 7. The push cylinder 4 is fixed by aligning it with different adjustment holes 72 and tightening the locking screw. This allows for quick adjustment to reduce the spacing when the distance between the push cylinders 4 is relatively large.
