Description
Technical Field
[0001] The utility model relates to the technical field of milling machine positioning devices, and specifically relates to a multi-clamping surface milling machine positioning device. Background Art
[0002] In the field of mechanical processing, especially in milling, workpiece positioning and clamping are key to ensuring machining accuracy and efficiency. Traditional milling machine positioning devices often use a single clamping method, such as a fixture or chuck. Although this method is simple, it often suffers from unstable clamping, easy shaking, or offset when processing lightweight workpieces with complex shapes or variable sizes, resulting in reduced machining accuracy and low machining efficiency.
[0003] To address these issues, researchers and engineers are constantly exploring new positioning and clamping technologies. Multi-clamping surface design has emerged as an effective solution. By placing clamping mechanisms at multiple locations on the workbench, multiple clamping surfaces of the workpiece can be clamped simultaneously, significantly improving workpiece stability and reducing vibration and offset during machining.
[0004] However, most existing multi-gripping surface positioning devices suffer from complex structures, cumbersome operations, and poor versatility. For example, some positioning devices require the use of multiple independent fixtures or chucks, which not only increases the cost and space occupied by the equipment, but also increases the complexity and difficulty of operation. Utility Model Content
[0005] The purpose of the utility model is to provide a positioning device for a multi-clamping face milling machine to solve the problems raised in the above background technology.
[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a positioning device for a multi-clamping surface milling machine, comprising a mounting table, a connecting rod being provided on the mounting table, a workbench being provided on the connecting rod, a mounting slot being provided on the workbench, and a light workpiece being provided in the mounting slot; two connecting arms are provided on the left and right side walls of the workbench, a rotating clamping plate is provided between the two connecting arms on each side, the side walls of the rotating clamping plate are abutted against the workbench, a threaded rotating rod is inserted on the front and rear sides of the rotating clamping plate, the outer end of the threaded rotating rod extends to the outer side of the connecting arm on the corresponding side; the threaded rotating rod is threadedly connected to the connecting arm, a locking plate is provided on the threaded rotating rod, the locking plate is located at the outer end of the rotating clamping plate, and when the threaded rotating rod is rotated, the locking plate fixes the rotating clamping plate.
[0007] Preferably, the mounting groove passes through the workbench from left to right, and both left and right ends of the light workpiece extend to the outside of the mounting groove.
[0008] Preferably, a butt plate is provided at the lower end of the connecting arm, a connecting rod is provided on the side wall of the butt plate, the outer end of the connecting rod passes through the lower side wall of the rotating splint, and a coil spring is sleeved on the connecting rod, and the coil spring is simultaneously located between the butt plate and the rotating splint.
[0009] Preferably, an auxiliary wrench is provided on the outer side wall of the rotating clamping plate.
[0010] Preferably, an auxiliary handle is provided at the outer end of the threaded rotating rod.
[0011] Compared with existing technologies, the present invention offers the following advantages: by providing connecting arms with rotating clamping plates on the left and right sides of the workbench and securing the rotating clamping plates with threaded rods and locking plates, the present invention can simultaneously clamp multiple clamping surfaces of a lightweight workpiece. This multi-clamping design significantly improves workpiece stability during machining, reduces machining errors caused by workpiece sway or deviation, and improves machining accuracy.
[0012] The mounting slot runs through the workbench, allowing both ends of the lightweight workpiece to extend outside the slot, facilitating flexible adjustment based on the workpiece's size and shape. This design enhances the positioning device's versatility and adaptability, enabling it to meet the machining needs of lightweight workpieces of varying sizes and types.
[0013] The abutment plate at the lower end of the connecting arm, the connecting rod, and the coil spring mounted on the connecting rod form a buffer mechanism. When a workpiece is subjected to external forces, this buffer absorbs some of the impact, reducing damage to the workpiece and the positioning device, protecting the workpiece surface from scratches or crushing, and extending the service life of the positioning device.
[0014] An auxiliary wrench is located on the outer wall of the rotating clamping plate, and an auxiliary handle is located on the outer end of the threaded rotating rod. These features allow operators to easily operate the rotating clamping plate and threaded rotating rod, completing the clamping and securing of the workpiece without the need for additional tools. This not only improves work efficiency but also reduces operational difficulty and labor intensity.
[0015] Compact structure and space saving: The entire positioning device is compact, with components tightly fitted together, and occupies minimal space. This facilitates layout and installation on the milling machine, improving workshop space utilization. The compact structure also contributes to improved stability and reliability of the positioning device. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0021] See also Figure 1-3 This utility model provides a technical solution: a multi-clamp face milling machine positioning device. In the field of modern machining, multi-clamp face milling machine positioning devices, with their superior flexibility and precision, have become an important tool for improving production efficiency and quality. Today, we will explore in depth a sophisticated and powerful multi-clamp face milling machine positioning device that not only retains the essence of traditional design but also incorporates numerous innovative details to meet increasingly complex machining needs.
[0022] The core component of the device is a stable mounting platform 1, serving as the foundation of the entire system, supporting the operation of all subsequent components. Atop this platform 1, a precisely machined connecting rod 2 stands upright, its top ingeniously connected to a multifunctional workbench 3. This workbench 3 not only serves as the primary platform for machining operations but also cleverly incorporates innovative design concepts, featuring a carefully designed mounting slot 4. This slot 4 not only extends from the left and right sides of the workbench 3, creating an open space, but also allows lightweight workpieces 5 to easily extend to the outside, enabling multi-angle clamping.
[0023] In order to achieve a secure clamping of the lightweight workpiece 5, two sets of connecting arms 6 are cleverly arranged on the left and right side walls of the workbench 3. A flexible rotating clamping plate 7 is installed between each set of connecting arms 6. The side walls of these rotating clamping plates 7 are tightly against the workbench 3, ensuring stability and accuracy during the clamping process. Even more cleverly, threaded rotating rods 8 are cleverly inserted on the front and back sides of the rotating clamping plates 7. These threaded rotating rods 8 not only have their outer ends extending to the outside of the corresponding connecting arms 6 for easy operation, but also are threadedly connected to the connecting arms 6, making the adjustment of the clamping force both precise and convenient.
[0024] When the operator needs to adjust the clamping force, he only needs to gently turn the auxiliary handle 9 on the threaded rotating rod 8 to fine-tune the position of the rotating clamping plate 7. During this process, the locking plate 10 on the threaded rotating rod 8 will move accordingly and fit tightly against the outer end of the rotating clamping plate 7, forming a solid locking barrier to ensure long-term and stable clamping force.
[0025] Furthermore, this device takes ease of use and safety into account. A support plate 11 is strategically positioned at the lower end of the connecting arm 6. Connecting rods 12 mounted on its sidewalls not only penetrate the lower wall of the rotating clamping plate 7 but also cleverly house coil springs 13. These coil springs 13 create an elastic buffer zone between the support plate 11 and the rotating clamping plate 7, effectively absorbing vibrations and impacts during machining, protecting the workpiece and equipment from damage, while also reducing operator workload.
[0026] In order to facilitate the operator to quickly adjust the clamping state or release the clamping in an emergency, an auxiliary wrench 14 is also thoughtfully provided on the outer wall of the rotating clamping plate 7. This small design detail allows the operator to handle complex processing tasks with ease and composure.
[0027] In summary, this multi-clamp face milling machine positioning device stands out in the machining industry for its unique design and exceptional performance. It not only improves machining efficiency and quality, but also significantly reduces operational difficulty and labor intensity, injecting new vitality into the company's production and development. In the future, we believe this device will be applied and promoted in a wider range of fields.
[0028] Working Principle: When the present invention is in operation, 1. the mounting table 1 is fixed to the milling machine, and the connecting rod 2 securely mounts the workbench 3 on the mounting table 1; a light workpiece 5 is placed in the mounting slot 4 on the workbench 3. Since the mounting slot 4 runs through the workbench 3 from left to right, both ends of the light workpiece 5 can extend to the outside of the mounting slot 4, facilitating clamping and positioning from both sides; connecting arms 6 are provided on both sides of the workbench 3, and a rotating clamping plate 7 is installed between each connecting arm 6. The side walls of the rotating clamping plate 7 abut against the workbench 3, forming an initial contact; threaded rotating rods 8 are inserted on both the front and rear sides of the rotating clamping plate 7, which are connected to the connecting arms 6 via a threaded connection, allowing position adjustment by rotation.
[0029] By rotating the outer end of the threaded turning rod 8 by the auxiliary handle 9, the threaded turning rod 8 will move inward due to the threaded connection between the threaded turning rod 8 and the connecting arm 6. As the threaded turning rod 8 moves, the locking plate 10 at its outer end gradually approaches and presses the rotating clamping plate 7, thereby fixing the rotating clamping plate 7 on the workbench 3 through friction. At the same time, since the lower end of the connecting arm 6 is provided with a butt plate 11 and a connecting rod 12, the connecting rod 12 passes through the rotating clamping plate 7 and is covered with a coil spring 13. The coil spring 13 generates elastic force between the butt plate 11 and the rotating clamping plate 7, which assists in the firm clamping of the rotating clamping plate 7 and provides a certain buffering effect.
[0030] An auxiliary wrench 14 is provided on the outer side wall of the rotating splint 7 to facilitate manual adjustment of the position of the rotating splint 7 when needed; an auxiliary handle 9 is provided at the outer end of the threaded rotating rod 8 to facilitate the operator to easily rotate the threaded rotating rod 8 for clamping and releasing operations.
[0031] Through the above working principle, the multi-clamping surface milling machine positioning device can achieve stable clamping of the light workpiece 5, and provide multiple clamping surfaces through the rotating clamping plates 7 on both sides, thereby improving the processing accuracy and stability.
