Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of mold production equipment, in particular to a four-axis turntable fixture and a mold processing device. Background Art
[0002] In the field of mechanical processing, fixtures are critical tools for ensuring machining accuracy and efficiency. With the development of the manufacturing industry, the demand for machining precision is increasing. Traditional fixed three-axis fixtures are no longer able to meet the demands of multi-faceted machining of complex parts. For example, in the production and processing of molds, multi-directional machining is required in a single setup to improve machining accuracy and efficiency. Existing die-casting molds are mostly processed using fixed three-axis fixtures. This means that in a single setup, only one surface is machined in one direction. The workpiece is then disassembled, repositioned in another direction, and then machined in another position, repeating this process until all positions are machined. This method has significant drawbacks: First, the multiple setups and tool setting processes can easily introduce errors, affecting machining accuracy; second, only one set of fixtures can be installed on a single machine tool at a time, consuming significant production resources. To address these issues, four-axis rotary table fixtures have emerged. These fixtures utilize the multi-angle rotation capability of a four-axis rotary table to achieve multi-directional machining in a single setup. Using a four-axis rotary table, workpieces can be machined at various angles, eliminating the need for multiple setups and tool setting, significantly improving machining accuracy and efficiency. However, the L-shaped connecting plate installed on the existing four-axis turntable, as a key component for supporting the bridge plate, is usually a split structure. This structure has assembly gaps, which can lead to large rotation errors of the four-axis turntable. Repeated adjustments are required during use, which seriously affects processing efficiency and cannot guarantee the processing quality of the product. In addition, the fixtures on the bridge plate are mostly manually operated, which cannot quickly clamp the workpiece, also resulting in reduced production efficiency.
[0003] Therefore, it is necessary to improve the existing four-axis turntable to overcome the defects of the prior art. Utility Model Content

[0028] The following describes preferred embodiments of the present invention in more detail with reference to the accompanying drawings. Although preferred embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. Rather, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.
[0029] In the description of the present invention, the directions or positional relationships indicated by the terms "up", "down", "left" and "right" are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and do not require that the present invention must be constructed and operated in a specific direction. Therefore, they should not be understood as limitations on the present invention.
[0030] The existing four-axis turntable fixture utilizes the multi-angle rotation characteristics of the four-axis turntable to achieve the purpose of one-time clamping and multi-directional processing. Through the four-axis turntable, the workpiece can be processed at different angles without multiple clamping and tool alignment, thereby greatly improving the processing accuracy and efficiency. However, the L-shaped connecting plate provided on the existing four-axis turntable, as a key component for supporting the bridge plate, usually adopts a split structure. This structure has an assembly gap, which will cause the four-axis rotation error of the four-axis turntable to be large. Repeated debugging is required during use, which will seriously affect the processing efficiency, and the processing quality of the product cannot be guaranteed. In addition, the fixtures on the bridge plate are mostly manually operated, and the workpiece cannot be clamped quickly, which will also lead to a decrease in production efficiency.
[0031] Based on this, the present application provides a four-axis turntable fixture.
[0032] See also Figures 1 to 5As shown, the present application provides a four-axis turntable fixture, including an L-shaped connecting plate 2 and a bridge plate 1. The L-shaped connecting plate 2 is designed as an integrally formed structure. Specifically, the L-shaped connecting plate 2 is composed of a first plate body 21 and a second plate body 22, and the first plate body 21 and the second plate body 22 are perpendicular to each other. In order to ensure the stability and precision of the structure, the first plate body 21 and the second plate body 22 are manufactured through an integral molding process, avoiding the assembly errors that may be caused by the traditional assembly structure. A mounting hole is provided on the first plate body 21 for fixing the entire fixture on the four-axis turntable.
[0033] In this embodiment, two L-shaped connecting plates 2 are provided, and the first plates 21 of the two L-shaped connecting plates 2 are arranged on the same plane, while the second plates 22 are parallel to each other. This design not only ensures the overall stability of the fixture, but also provides it with sufficient supporting strength.
[0034] The bridge deck 1 is mounted on the first plate 21 of two L-shaped connecting plates 2. The bridge deck 1 is designed to span the two L-shaped connecting plates 2, forming a stable work platform. A product placement area 12 is provided on the bridge deck 1 for placing products to be processed. Product placement area 12 is designed based on the specific shape and size of the product to ensure that the product can be securely placed on the bridge deck 1.
[0035] To further secure the product, a locking mechanism 3 is installed on the bridge 1. This mechanism comprises a locking drive 31 and a pressure block 32. The locking drive 31 is fixed to the bridge 1 and, through its internal drive mechanism (e.g., a cylinder, electric push rod, etc.), drives the pressure block 32 up and down. When a product is placed in the product placement position 12, the locking drive 31 activates, driving the pressure block 32 downward, thereby compressing the product and maintaining its stability throughout the processing process.
[0036] During actual use, the entire fixture is first fixed to the four-axis turntable through the mounting holes. Then, the product to be processed is placed on the product placement position 12. Next, the locking drive device 31 is started to drive the pressure block 32 to move downward, pressing the product tightly against the bridge plate 1. Finally, the four-axis turntable is started for processing operations. Due to the integrated design of the L-shaped connecting plate 2, the accuracy and stability of the entire fixture are significantly improved. At the same time, the automated design of the locking structure 3 enables rapid locking and unlocking of the product, greatly improving production efficiency.
[0037] Specifically, a mounting opening 11 is provided on the bridge plate 1 , the locking drive device 31 is fixed at the bottom of the mounting opening 11 , and the output end of the locking drive device 31 passes through the mounting opening 11 ;
[0038] A support plate 13 is provided on one side of the installation opening 11, a connecting arm 14 is provided on the support plate 13, and the pressing block 32 is provided on the connecting arm 14 and hinged to the connecting arm 14;
[0039] The pressing block 32 has a first end and a second end opposite to each other. The first end of the pressing block 32 is located above the product placement position 12 , and the second end of the pressing block 32 is hinged to the output end of the locking drive device 31 .
[0040] The design of the mounting opening 11 enables the locking drive device 31 to be firmly fixed at the bottom of the mounting opening 11. The output end of the locking drive device 31 passes through the mounting opening 11 so as to be connected to the pressure block 32. A support plate 13 is provided on one side of the mounting opening 11, and a connecting arm 14 is provided on the support plate 13. The connecting arm 14 is designed to support and connect the pressure block 32. The pressure block 32 is provided on the connecting arm 14 and is hinged to the connecting arm 14. This hinged design enables the pressure block 32 to rotate freely within a certain range, thereby better adapting to products of different shapes and sizes. The pressure block 32 has a first end and a second end relative to each other. The first end of the pressure block 32 is located above the product placement position 12. When the locking drive device 31 is started, the first end of the pressure block 32 will move downward to press the product in the product placement position 12. The second end of the pressing block 32 is hinged to the output end of the locking drive device 31. This hinged design not only ensures a stable connection between the pressing block 32 and the locking drive device 31, but also makes the pressing block 32 more flexible and stable during movement.
[0041] In actual use, the product to be processed is placed on the product placement position 12, and the locking drive 31 is activated. The output end of the locking drive 31 pushes the pressing block 32 to rotate about its hinge point with the connecting arm 14, causing the first end of the pressing block 32 to move downward and compress the product. Because the pressing block 32 utilizes an articulated design with the connecting arm 14 and the locking drive 31, the pressing block 32 maintains a stable position during the product compression process, preventing deviation or shaking caused by uneven force.
[0042] Furthermore, a friction member is provided on the second end of the pressing block 32; the friction member can be a friction pattern provided on the second end, which is used to enhance the friction between the second end and the product, thereby being able to more effectively compress and fix the product.
[0043] Furthermore, a plurality of the locking drive devices 31 are provided on the bridge plate 1 , and the plurality of the locking drive devices 31 are all provided at the edge of the product placement position 12 .
[0044] Multiple locking actuators 31 can be evenly distributed around the edges of the product placement area 12. Each locking actuator 31 is fixed to the bottom of a specific mounting opening 11 on the bridge plate 1, with its output end extending through the mounting opening 11 and connected to a pressure block 32. This layout ensures that the product is subjected to uniform and stable clamping force throughout the entire processing process, thereby preventing processing errors or product damage caused by uneven force.
[0045] Furthermore, a pad is provided on the edge of the product placement position 12, and a card slot is provided on the edge of the pad.
[0046] The backing plate adjusts the shape of the product placement area 12, expanding its applicability and accommodating a wider range of products. The slot is designed to mate with the edge or specific structure of the product to further enhance the stability and secureness of the product placed on the product placement area 12. The slot's interaction with the product effectively prevents movement or offset during processing, thereby ensuring processing accuracy and product quality.
[0047] Furthermore, a wiring member 4 is provided at the bottom of the bridge plate 1 . The wiring member 4 is fixed to the bottom of the bridge plate 1 by bolts. A wiring groove 41 is provided in the wiring member 4 .
[0048] The wiring member 4 is used to organize the wiring of the components of the four-axis turntable. For example, the locking drive device 31 requires a mains power connection via a wire. The wiring member 4 allows the wires to be clipped into the wiring groove 41, effectively securing the wires and reducing wear. It also minimizes the impact of the wires on the operation of the four-axis turntable, ensuring stable operation.
[0049] Furthermore, a mounting shaft hole 221 is provided on the second plate body 22 , and the axes of the mounting shaft holes 221 of the two L-shaped connecting plates 2 coincide with each other.
[0050] The mounting hole 221 is used to securely connect to a drive shaft that drives the fixture, such as a drive shaft of a machine tool, allowing the machine tool to drive the fixture to rotate. Because the axes of the mounting hole 221 coincide with each other, the fixture maintains a stable position during rotation, avoiding machining errors or product damage caused by uneven rotation.
[0051] Furthermore, a plurality of hollow positions 222 are provided on the second plate body 22 .
[0052] The design of the hollow portion 222 can significantly reduce the weight of the second plate 22. By removing unnecessary material while maintaining sufficient strength and rigidity, the mass of the entire fixture can be reduced, thereby reducing the energy consumption required by the machine tool to drive the fixture to rotate and improving the working efficiency of the machine tool.
[0053] Example 2
[0054] This embodiment further provides a mold processing device, which includes a main body, and the four-axis turntable fixture as described above is provided on the main body.
[0055] During the mold processing process, the mold to be processed is first placed on the product placement position 12 of the four-axis rotary table fixture. By adjusting the locking drive 31, the pressing block tightly presses the mold, ensuring that it does not move or wobble during processing. Then, based on the processing requirements, the control system on the main body controls the four-axis rotary table fixture to precisely move and rotate in all four axes, achieving complex processing operations.
[0056] Thanks to the high-precision adjustment and rotation capabilities of the four-axis rotary table fixture, this mold processing device can perform complex mold processing operations while maintaining high processing accuracy. Moreover, the mold processing device can adapt to the processing requirements of molds of different shapes and sizes, improving the versatility and flexibility of the equipment.
[0057] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
