Description

Technical Field

[0001] This utility model relates to the field of machining technology, specifically to a modular fixture base plate. Background Technology

[0002] In the field of machining, machining fixtures are indispensable key components. They are typically securely mounted on the machining center's worktable, undertaking the crucial task of accurately holding the workpiece to ensure the smooth completion of machining, mold manufacturing, and parts assembly processes, while also preventing direct contact between the cutting tool and the machining center's table surface. These fixtures are generally made of high-strength, high-precision materials to meet the stringent requirements of the machining process.

[0003] However, existing machining fixture base plates have significant limitations. Due to their poor versatility, when dealing with workpieces of different shapes and sizes, it is often necessary to design base plates and clamping holes specifically to match them. When the production line changes products, the original fixture base plates can no longer be used, and fixture base plates must be redesigned and manufactured for the new products, which prolongs the production line development cycle, and the high requirements for fixture base plate materials also increase material costs. Utility Model Content

[0022] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0023] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0024] A modular fixture base plate, please refer to the appendix. Figure 3 and Figure 2 One possible implementation is as follows: It includes at least one standard module, preferably with the same length and width (i.e., a square cross-section). The standard modules can be spliced ​​along their length and / or width. The top of each standard module has a horizontal clamping slot 4 and a vertical clamping slot 5, both of which are inverted T-shaped slots. During splicing, the clamping slots of adjacent standard modules are aligned. The standard module also has a through mounting hole 6 extending through its thickness. (See appendix.) Figure 3 There are two horizontal clamping slots 4 and two vertical clamping slots 5, which divide the standard module into a nine-square grid. The mounting hole 6 is a countersunk hole located in the center of the standard module. A single standard module can be fixed to the table of the machining center through the mounting hole 6 and bolts.

[0025] Further, see appendix. Figure 3 The standard module includes a module body 1 and splicing rods 2. The module body 1 is a steel block. There are at least two splicing rods 2, which protrude from two adjacent sides around the module body 1, preferably two rods in each direction. On the module body 1, splicing holes 3 are provided on the side opposite to the side where the splicing rods 2 are provided. The positions of the splicing holes 3 and the splicing rods 2 correspond.

[0026] In the above embodiments, the device is used as follows: First, select an appropriate number of standard modules according to the fixture design and clamping requirements to be processed. Then, splice the standard modules by using splicing rod 2 and splicing hole 3. During splicing, ensure that the horizontal clamping slots and vertical clamping slots of adjacent standard modules are aligned with each other to form a modular fixture base plate structure that meets the processing size requirements.

[0027] Next, using the mounting holes and bolts, the assembled modular fixture base plate is fixed to the machining center table. Since adjacent module bodies 1 are connected by splicing rods 2, when fixing the assembled module bodies 1 to the machining center table, it is not necessary to connect the mounting holes 6 of each module body 1 to the machine tool table; only the module bodies 1 at the edges need to be fixed to the machining center table. If the assembled assembly is large, several mounting holes 6 in the middle can also be selected for fixing.

[0028] Finally, the workpiece is clamped to the fixture body, and then the fixture body is connected to the fixture base plate to achieve workpiece clamping. Due to the design of the horizontal clamping slot 4 and the vertical clamping slot 5 on the fixture base plate, the fixture body can be fixed to the fixture base plate relatively flexibly. The specific installation process is as follows: the bolt is placed upside down in the horizontal clamping slot 4 / vertical clamping slot 5 and its position is adjusted by sliding. Then, the fixture body is inserted along the bolt axis and attached to the surface of the fixture base plate. The bolt passes through the preset hole on the fixture body and is tightened with a nut. When the width of the bolt nut is the same as the width of the clamping slot, the rotation of the bolt during tightening can be restricted.

[0029] In existing technologies, fixture base plates are generally made of a single piece of steel plate. Holes are drilled to accommodate the fixture body and its connection to the machine tool table. This allows the fixture body to be mounted on the machine tool table. Therefore, fixture base plates are non-standard parts, requiring redesign and remanufacturing each time a product line is changed. This not only affects production line changeover time but also increases costs.

[0030] Compared to existing solutions, this solution utilizes a modular fixture substrate design, achieving versatility and reconfigurability through the splicing of standard modules. In practical applications, users can flexibly select the number and splicing method of standard modules according to the size and shape requirements of different workpieces. If the production line changes products, the original substrate can be disassembled and reassembled to quickly construct fixture substrates adaptable to various processing scenarios. This design not only improves the utilization rate of the fixture substrate but also significantly reduces the cost and time required to redesign and manufacture fixture substrates when changing product lines.

[0031] In one possible implementation, the splicing hole 3 penetrates the module body 1, and the middle part of the splicing rod 2 is threaded into the module body 1, but both ends are smooth guide surfaces to ensure splicing accuracy. One end of the splicing rod 2 is located inside the module body 1, and the other end extends beyond the end face of the module body 1. The horizontal and vertical splicing holes 3 are staggered in thickness. Alternatively, the splicing hole 3 is a blind hole, and splicing holes 3 are provided on all four sides of the module body 1. In each of the two sets of opposite sides, a splicing rod 2 protruding from the end face is provided on one of the sides.

[0032] Specifically, when the splicing hole 3 is a through hole, the splicing rod 2 has a threaded middle section and magnets with opposite polarities at both ends. When the splicing hole 3 is a blind hole, the splicing rod 2 has a threaded end connected to the module body 1, and the protruding end is magnetic. The beneficial effect is that the magnets further enhance the splicing's robustness and stability. During splicing, the splicing rods of adjacent modules can attract each other magnetically, achieving rapid and accurate positioning and splicing, greatly improving splicing efficiency and accuracy. Simultaneously, this design also makes the modular fixture substrate easier and faster to disassemble and reassemble, improving the reconfigurability and versatility of the fixture substrate.

[0033] In one possible implementation, see Appendix Figure 1 The outer periphery of the standard module is provided with an intrusion groove 7. When two adjacent standard modules are spliced, the intrusion grooves 7 combine to form a through area. The intrusion grooves 7 on adjacent sides are staggered in height. After multiple standard modules are spliced, screws can be inserted into the through area, and then nuts are tightened at both ends to press the two ends of the spliced ​​fixture base plate together, connecting multiple module bodies 1 into one unit. The intrusion grooves 7 are staggered in the horizontal and vertical thickness directions, so the screws will not interfere with each other. Its advantage is that, through the cooperation of the intrusion grooves, screws, and nuts, the overall stability of multiple standard modules after splicing can be enhanced. Not only is the installation process simple, but the fixture base plate also has high integrity. This connection method is not limited by the number of modules spliced. No matter how many standard modules are spliced, the entire fixture base plate can be firmly connected together by inserting screws and tightening nuts, further improving the practicality and reliability of the modular fixture base plate.

[0034] In one possible implementation, see Appendix Figure 1 It also includes a clamping body 8, which is installed on the top surface of the assembled standard module via a clamping groove. The clamping body 8 includes a base 81, clamping blocks 82, and a lead screw 83. The base 81 has holes for connecting to the standard module and a guide groove. The lead screw 83 is positioned along the guide groove with opposite thread directions at both ends. Two clamping blocks 82 are respectively positioned at both ends of the lead screw 83, and the clamping blocks 82 slide in engagement with the guide groove. The usage process is as follows: When workpiece clamping is required, firstly, according to the size and shape of the workpiece, a suitable number of standard modules are assembled according to the above splicing method to form a modular fixture base plate structure that meets the processing size requirements, and then fixed to the table of the machining center. Next, a suitable fixture body 8 is selected, and the hole on the base 81 of the fixture body 8 is aligned with the horizontal clamping slot 4 or vertical clamping slot 5 on the modular fixture base plate. The bolt is placed upside down into the clamping slot and slid to adjust it to a suitable position. Then, the fixture body 8 is placed along the bolt axis and attached to the surface of the fixture base plate, so that the bolt passes through the preset hole on the base 81. Finally, the fixture body 8 is fastened to the fixture base plate with a nut. Afterward, the workpiece to be processed is placed between the two clamping blocks 82 of the fixture body 8. By rotating the lead screw 83, since the threads at both ends of the lead screw 83 turn in opposite directions, the two clamping blocks 82 will move towards the middle at the same time, thereby clamping the workpiece.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features.
