Description

Technical Field

[0001] This utility model belongs to the field of mechanical processing technology, and specifically relates to a connecting base with high positioning accuracy. Background Technology

[0002] Machining refers to the entire process of transforming a raw material into a qualified part by using machining methods according to the drawings and dimensions, ensuring the shape, size, relative position, and properties of the blank. Its purpose is to transform raw materials or blanks into finished or semi-finished products that meet design requirements through a series of processing steps. The machining process typically includes blank manufacturing, rough machining, finish machining, assembly, inspection, and packaging. Rough machining primarily removes most of the excess material from the blank, while finish machining focuses on achieving the dimensions and precision required by the drawings. Assembly combines the individual parts into a whole, inspection ensures the product quality meets design requirements, and finally, packaging prepares the product for shipment.

[0003] A connecting base is a component used to connect mechanical workpieces, equipment, machines, or instruments. Its main function is to fix the equipment to achieve stable support and load transfer. Based on shape and design, connecting bases can be divided into various types, such as flat plate type, box type, T-slot type, and special-purpose type. Each type adapts to different processing needs, ensuring processing accuracy and stability. Depending on the application scenario, connecting bases can also be divided into hydraulic support bases, machine tool mounting bases, etc.

[0004] Specifically, connecting bases are typically made of high-strength, highly corrosion-resistant materials, such as alloy steel and stainless steel. Traditionally, connecting bases are made of a single piece of metal when assembling machining fixtures. However, in actual machining operations, the varying sizes of workpieces required for clamping often lead to dimensional mismatches when assembling fixtures using connecting bases. To solve this problem, operators usually need to change to different types of fixtures, a process that often involves disassembling and reassembling the entire connecting base. Frequent disassembly and reassembly not only increases workload but, more importantly, can reduce the overall accuracy of the connecting base, thus negatively impacting the quality of subsequent machining. Utility Model Content

[0022] 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.

[0023] Please see Figure 1-4 The present invention provides the following technical solution: a connection base with high positioning accuracy, including a mounting bracket 1 and a support base 2 mounted on the top of the mounting bracket 1, a docking base 3 connected to the top opening of the support base 2, a docking plate 4 connected to the surface of the docking base 3, and a support block 5 connected to the inner wall of the opening of the support base 2.

[0024] Both ends of the support base 2 are connected to side blocks 6. A movable rod 7 is connected to one side opening of the side block 6. A linkage plate 8 is connected to the other end of the movable rod 7. A linkage spring 9 is connected to one side of the linkage plate 8. A retaining strip 10 is connected to the side of the linkage plate 8 opposite to the linkage spring 9.

[0025] Preferably, the surface dimensions of the docking base 3 are adapted to the opening dimensions of the support base 2, and the bottom end of the docking base 3 contacts the surface of the support block 5. By using a split-type connecting base, the machine tool is installed by the support base 2. After disassembling the docking base 3, it is convenient to quickly change the clamps of the machining fixture and then reassemble it. In this process, the split-type connecting base will not affect the docking accuracy due to disassembly, thus improving the processing efficiency.

[0026] Preferably, the other end of the linkage spring 9 is connected to the inner wall of the opening of the side block 6, and the linkage spring 9 and the linkage plate 8 form an elastic telescopic structure. A slot is provided on the side of the docking base 3 near the locking strip 10, and the locking strip 10 and the slot on one side of the docking base 3 form an interlocking structure. By pulling the movable rod 7, the linkage plate 8 can be easily driven to squeeze the linkage spring 9, thereby facilitating the movement of the locking strip 10. This facilitates the stable assembly of the split-type connecting base and improves the accuracy of the connecting base docking.

[0027] Preferably, a clamping plate 11 is connected to the surface of the mating plate 4, and a clamping block 12 is connected to one side of the clamping plate 11. Two sets of clamping blocks 12 are provided, and the two sets of clamping blocks 12 are symmetrically arranged about the longitudinal central axis of the mating plate 4. By using the clamping block 12 on one side of the clamping plate 11, it is convenient to clamp and stabilize the machining fixture, and improve the assembly stability between the machining fixture and the connecting base.

[0028] Preferably, a sliding block 13 is connected to the bottom end of the clamping plate 11. The sliding block 13 has a T-shaped structure, and a sliding groove 14 is formed on the surface of the docking base 3 near the sliding block 13. The sliding block 13 and the sliding groove 14 form a sliding connection structure. By sliding the sliding block 13 along the sliding groove 14, the clamping plate 11 can be moved stably on the surface of the docking plate 4, thus preventing the clamping plate 11 from shifting during movement.

[0029] Preferably, a threaded block 15 is connected to the center of the bottom end of the clamping plate 11. A screw 16 is connected through the surface of the threaded block 15, passing through the docking base 3 and extending to the outside of the docking base 3. The other end of the screw 16 is connected to a bearing 17, and the inner side of the bearing 17 is connected to the inner wall of the opening of the docking base 3. By rotating the screw 16, it is easy to drive the screw 16 to rotate along the inner lining of the bearing 17, and at the same time drive the threaded block 15 to move in a direction along the screw 16, thereby improving the movement effect of the clamping plate 11.

[0030] The working principle of this utility model is as follows: First, the fixture used for machining the workpiece is placed on the docking plate 4. During this process, the docking base 3 is placed at the opening of the support base 2. Then, the bottom surface of the docking base 3 contacts the support block 5 inside the support base 2. At the same time, the movable rod 7 on one side of the side block 6 is pulled, which moves the locking strip 10 on one side of the linkage plate 8. At this time, the movable rod 7 is released, the compressed linkage spring 9 rebounds, and the locking strip 10 is reset. The locking strip 10 is engaged with the opening on one side of the docking base 3, which facilitates the assembly of the support base 2 and the docking base 3 into a whole. This allows for quick clamping of the fixture used for machining the workpiece and adapts to fixtures of different sizes. In addition, the use of a split-type connecting base improves the accuracy of positioning and docking, thereby improving the quality of the machined workpiece. In addition, rotating the screw 16 causes the threaded block 15 to move along the screw 16. At this time, the clamping plate 11 slides on the surface of the docking plate 4, and the sliding block 13 at the bottom of the clamping plate 11 slides along the sliding groove 14 on the surface of the docking base 3. This facilitates the control of the clamping plate 11 to clamp and stabilize the machining fixture, improves the efficiency of the connection base and the machining fixture assembly, and improves the production efficiency of the processed parts.
