Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of fixtures, and in particular to a multi-station fixture for processing hardware parts. Background Technology
[0002] Tools and accessories made from metal through processing and casting are widely used in many fields such as machinery manufacturing, electronic products, furniture decoration, construction industry, and automobile manufacturing. Hardware parts need to go through processes such as cutting, stamping, and drilling during processing. In order to improve the efficiency of hardware parts processing and reduce the steps of handling the workpiece, factories often clamp many hardware parts together for batch processing, so multi-station fixtures are used. However, current multi-station fixtures are actually just increasing the number of fixtures. One fixture can still only hold a single hardware part, and the existing fixtures are inconvenient to handle when using them. Utility Model Content
[0003] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a multi-station fixture for hardware processing.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: a multi-station fixture for processing hardware parts, including a processing surface, multiple cylinders installed on one side of the processing surface, multiple mounting blocks installed on the other side of the processing surface, a clamping assembly provided between adjacent mounting blocks, the clamping assembly including a driving block and two moving blocks, a retaining strip provided on both sides of the driving block, two moving blocks corresponding to two retaining strips, and a retaining groove provided on the side of the two moving blocks facing the corresponding retaining strip, the retaining groove being slidably connected to the retaining strip, a pressing block installed on both sides of the moving block, and a workpiece provided between the pressing block and the mounting block;
[0005] Through the above technical solution, the cylinder moves the drive block towards the moving block via the drive rod. At this time, the clamping strip slides in the clamping groove, and the moving blocks move away from each other, so that the extrusion block extrudes the workpiece and fixes the workpiece between the extrusion block and the mounting block. This setting facilitates the placement of the workpiece.
[0006] Furthermore, the drive blocks are all positioned between adjacent mounting blocks and are arranged on the same axis as the cylinder.
[0007] Furthermore, the drive block is trapezoidal in shape, the two card strips are respectively disposed on the two inclined surfaces of the drive block, the side of the two moving blocks facing the card strips is set as an inclined surface, and the card slot is disposed on the inclined surface.
[0008] Furthermore, a drive rod is fixedly connected to the drive end of the cylinder, and the drive rod passes through the machined surface and is connected to the drive block.
[0009] Furthermore, multiple mounting slots are provided on the machining surface, and each mounting slot is equipped with a return spring. One end of each return spring is connected to a connecting block, and each connecting block is installed on the side of the moving block closest to the machining surface.
[0010] Compared with the prior art, the beneficial effects of this utility model are:
[0011] In this invention, the cylinder uses a drive rod to bring the drive block close to the processing surface. The drive block, through the clamping strip and the clamping groove, enables the moving blocks to push each other and the pressing blocks to press the workpiece. This design makes the clamping and picking up of the workpiece very convenient and fast. In use, one drive source can clamp two workpieces at the same time, thereby increasing the number of workstations and improving the processing efficiency of hardware parts.

[0017] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] Reference Figure 1-3This utility model provides an embodiment of a multi-station fixture for processing hardware parts, including a processing surface 1. Multiple cylinders 2 are installed on one side of the processing surface 1, and multiple mounting blocks 3 are installed on the other side of the processing surface 1. A clamping assembly is provided between adjacent mounting blocks 3. The clamping assembly includes a driving block 5. A retaining strip 7 is provided on both sides of the driving block 5. A retaining groove 9 is slidably connected to both sides of the retaining strip 7. The retaining groove 9 is located inside the moving block 10. A pressing block 6 is installed on both sides of the moving block 10. A workpiece 4 is placed between both sides of the pressing block 6 and the mounting block 3. The cylinder 2 moves the driving block 5 towards the moving block 10 through the driving rod 8. At this time, the retaining strip 7 slides in the retaining groove 9, and the moving blocks 10 move away from each other, so that the pressing block 6 presses the workpiece 4 to fix the workpiece 4 between the pressing block 6 and the mounting block 3. This arrangement facilitates the placement and clamping of the workpiece 4.
[0019] In this embodiment, the drive blocks are all positioned between adjacent mounting blocks and are on the same axis as the cylinder. The adjacent mounting blocks 3 can act as resistance against the workpiece 4, so that the cylinder 2 can push the workpiece 4 to clamp it between the mounting blocks 3. The drive block 5 is trapezoidal in shape, specifically an inverted trapezoid, that is, a structure that is wider at the top and narrower at the bottom. The two clamping strips 7 are respectively set on the two inclined surfaces of the drive block 5. The side of the two moving blocks 10 facing the clamping strips 7 is set as an inclined surface, and the slot 9 is set on the inclined surface. As the drive block 5 moves up and down, the two clamping strips 7 are used to make the moving blocks 10 move laterally, thereby moving closer to or away from the mounting blocks 3.
[0020] In this embodiment, the driving end of the cylinder 2 is fixedly connected to a driving rod 8. The driving rod 8 passes through the machining surface 1 and is connected to the driving block 5. The cylinder 2 can drive the driving block 5 to work through the driving rod 8, thereby achieving the clamping and releasing of the workpiece 4.
[0021] In this embodiment, multiple mounting slots 11 are provided on the processing surface 1. Each mounting slot 11 is equipped with a return spring 12. One end of each return spring 12 is connected to a connecting block 13. The connecting block 13 is installed on the side of the moving block 10 close to the processing surface 1. When the driving block 5 moves away from the processing surface 1, the return spring 12 presses the connecting block 13 to make the moving blocks 10 move closer to each other, thereby releasing the workpiece 4 and removing the workpiece.
[0022] Working principle: When clamping the workpiece, the cylinder 2 drives the drive block 5 to move towards the moving block 10 via the drive rod 8. At this time, the clamping strip 7 slides in the clamping groove 9, and the moving blocks 10 move away from each other, so that the pressing block 6 presses the workpiece 4 to fix the workpiece 4 between the pressing block 6 and the mounting block 3, thus quickly clamping the workpiece 4. When removing it, the drive block 5 is driven away from the processing surface 1 by the cylinder 2, and the return spring 12 presses the moving blocks 10 together via the connecting block 13 to make them move closer to each other, so that the workpiece 4 is quickly released, and the workpiece 4 can be quickly picked up, resulting in high processing efficiency.
[0023] The above embodiments are preferred embodiments of this utility model. All structures similar to this utility model and equivalent changes thereof should fall within the protection scope of this utility model.
