[0032] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.
[0033] like Figure 3-10 The image shows a continuous milling fixture for the glue inlet as described in this embodiment. This milling fixture is used to mill excess material at the glue inlet position on workpiece 8. Wherein... Figure 1 , 2 As shown, the top surface of the workpiece 8 has a concave-convex structure, and the excess material after processing is located at the edge of the top surface of the workpiece 8. The milling fixture includes a machining table 1, a pusher device, and a milling mechanism. The machining table 1 is fixedly arranged on a bottom platform. A guide groove 2 is machined on the machining table 1. The guide groove 2 extends along a preset direction, and its width is adapted to the width of the workpiece 8 to guide the workpiece 8 to move in a sequential order. The opening of the guide groove 2 is located on the top surface of the machining table 1. The guide groove 2 has two facing sidewalls in the width direction. Several limiting protrusions 21 are arranged at intervals along the depth direction of the guide groove 2 on the two sidewalls. The limiting protrusions 21 extend along the length direction of the guide groove 2. The limiting protrusions 21 are adapted to the preset grooves on the sidewalls of the workpiece 8. When the workpiece 8 enters the guide groove 2, the limiting protrusions 21 and the grooves on the workpiece 8 interlock in the length direction of the guide groove 2 to restrict the movement of the workpiece 8 in the depth direction of the guide groove 2. The aforementioned guide groove 2 has an upstream side and a downstream side along its length. The workpiece 8 is conveyed from the upstream side to the downstream side within the guide groove 2.
[0034] In the specific structural design, the processing table 1 includes two separate parts 11 that combine to form the processing table 1. A guide groove 2 is formed between the two separate parts 11. By dividing the processing table 1 into two separate parts 11, the ease of processing the guide groove 2 is improved, meeting the processing requirements of the complex structure of the guide groove 2. The guide groove 2 is arranged at an angle, both vertically and horizontally. A receiving groove 9 is installed at the lower end of the inclined guide groove 2. The receiving groove 9 is also arranged at an angle, both vertically and horizontally. The workpiece 8 can be output through the lower end of the guide groove 2 and received by the receiving groove 9 for guided and centralized recycling.
[0035] It should be noted that by reasonably designing the depth of the guide groove 2, when the workpiece 8 moves in the guide groove 2, the top surface of the workpiece 8 and the excess material are exposed outside the guide groove 2, which is beneficial to the milling operation.
[0036] The milling fixture in this embodiment includes a vibratory feeder 91. This vibratory feeder 91 is a conventional material feeding device of the prior art, and its specific structure can be adaptively adjusted according to the structure of the workpiece 8 to meet the material feeding requirements of the workpiece 8. The discharge end of the vibratory feeder 91 is connected to the upstream end of the guide groove 2 for conveying the workpiece 8 into the guide groove 2. Alternatively, in this embodiment, manual feeding can also be used to insert the workpiece 8 into the guide groove 2.
[0037] The aforementioned pushing device is arranged on one side of the processing table 1 to push the workpiece 8 in the guide groove 2 from the upstream side to the downstream side. Specifically, the pushing device includes a toggle member 5, a first driving unit, and a second driving unit 7. The toggle member 5 is arranged above the processing table 1, facing the opening of the guide groove 2. The toggle member 5 has a toggle end close to the guide groove 2. The toggle end of the toggle member 5 cooperates with the concave and convex structures on the workpiece. In this embodiment, the toggle end of the toggle member 5 is a fork-shaped structure, formed by two insert plates spaced apart along the length of the guide groove 2. The first driving unit is drively connected to the toggle member 5 to drive the toggle member 5 to reciprocate along the length of the guide groove 2. More specifically, the first driving unit includes a base 6, a slider 61 mounted on the base 6 and movable along the length of the guide groove 2, and a driving assembly for driving the slider 61 to reciprocate. An extension plate 62 is fixedly mounted on the slider 61 and extends to one side above the processing table 1. The actuating element 5 is fixed at a preset position on the extension plate 62 so as to correspond vertically to the guide groove 2.
[0038] The aforementioned second drive unit 7 is used to drive the actuating member 5 to move towards or away from the opening of the guide groove 2. The first drive unit and the second drive unit 7 are mutually driven and cooperate with each other. More specifically, the aforementioned second drive unit 7 is preferably a cylinder or an electric push rod. The drive end of the second drive unit 7 is connected to the base 6 to drive the base 6 to reciprocate along the depth direction of the guide groove 2.
[0039] Through the above structural design, with the cooperation of the first driving unit and the second driving unit 7, the actuating member 5 can move along the depth direction of the guide groove 2 and along the length direction of the guide groove 2. When the actuating member 5 moves towards the workpiece 8 in the guide groove 2 to a preset position, the actuating end of the actuating member 5 and the concave and convex structures on the workpiece 8 can form a limiting fit in the length direction of the guide groove 2. At this time, when the actuating member 5 is driven to move along the length direction of the guide groove 2, it can push the workpiece 8 to move in the guide groove 2.
[0040] In this embodiment, the aforementioned drive assembly includes a first rack 66, a gear assembly 65, a second rack 64, and a linear actuator 63. The first rack 66 is fixedly mounted on the slider 61 and extends along the length of the guide groove 2. The second rack 64 is mounted on the base 6 via a slide rail or groove, allowing it to slide along the length of the guide groove 2. The second rack 64 extends along the length of the guide groove 2. The first rack 66 and the second rack 64 are connected by the gear assembly 65. The gear assembly 65 engages to allow relative linear movement between the first rack 66 and the second rack 64. The linear actuator 63 is mounted on the base 6 and has a drive end that moves linearly. The linear actuator 63 is preferably a cylinder or an electric actuator. The drive end of the linear actuator 63 is connected to the second rack 64. With the above structural design, when the linear actuator 63 drives the second rack 64 to move, under the transmission of the gear assembly 65, it drives the first rack 66 to move, thereby enabling the actuating member 5 to move back and forth along the length direction of the guide groove 2. The gear assembly 65 consists of several gears rotating around their own center, and the specific assembly and mating methods are existing technologies.
[0041] The aforementioned milling mechanism includes a milling cutter 4 and a rotary driver 41 for driving the milling cutter 4 to rotate. The milling cutter 4 is arranged facing the opening of the guide groove 2, and the central axis of the milling cutter 4 extends along the width direction of the guide groove 2. A milling gap is formed between the milling cutter 4 and the opening of the guide groove 2. When the workpiece 8 moves sequentially within the guide groove 2, the milling cutter 4 can contact the inlet position on the workpiece 8 to perform milling operations.
[0042] In this embodiment, a limiting block 3 is installed on the machining table 1. The limiting block 3 is arranged facing the opening of the guide groove 2, and a limiting distance is formed between the limiting block 3 and the guide groove 2 in the depth direction of the guide groove 2. The milling end of the milling cutter 4 and the limiting block 3 are positioned on opposite sides of the guide width direction. When the workpiece 8 moves to the position of the limiting block 3, the limiting block 3 further limits the workpiece 8 in the depth direction of the guide groove 2 to improve the stability of the milling process.
[0043] In practical use, workpieces 8 sequentially enter the guide groove 2. With the cooperation of the first drive unit and the second drive unit 7, the actuating element 5 moves along the depth direction of the guide groove 2 to approach the workpiece 8 within the guide groove 2. The actuating end of the actuating element 5 and the concave-convex structure on the workpiece 8 form a limiting fit along the length direction of the guide groove 2. Then, the actuating element 5 moves again, pushing the workpiece 8 a preset distance along the length direction of the guide groove 2. Through the reciprocating motion of the actuating element 5, each workpiece 8 can be pushed to move sequentially along the guide groove 2. When passing the rotating milling cutter 4, the milling cutter 4 contacts the glue inlet position of the workpiece 8 to mill off excess material. In the above method, milling can remove excess material from the workpiece 8 at the glue inlet position, achieving high milling accuracy, excellent dimensional accuracy control, and continuous cleaning of the workpiece 8. This results in high work efficiency, saves time and labor, effectively meets the batch production processing needs of the workpiece 8, and is highly practical.
