Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of milling machine accessories, specifically to a milling machine machining fixture that can be quickly disassembled. Background Technology
[0002] With the rapid development of modern manufacturing, milling machines have become crucial in metal cutting. As a key component in milling, the performance of milling machine fixtures directly affects machining efficiency and accuracy. Traditional milling machine fixtures mostly employ a fixed design, resulting in limited clamping range, insufficient flexibility, and high maintenance costs. Traditional milling machine fixtures often use a fixed clamping method, limiting the clamping range and making it difficult to adapt to the machining needs of workpieces of different sizes and shapes. This leads to frequent fixture changes or workpiece position adjustments during actual machining, reducing machining efficiency. Traditional fixture designs often lack flexibility and cannot quickly adapt to changes in machining tasks. Once the fixture design is completed, its clamping method and clamping force are often fixed, making it difficult to meet diverse machining needs. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution:
[0005] A quick-detachable milling machine machining fixture includes a milling machine table, with fixed end seats symmetrically arranged at both ends of the top surface of the milling machine table, and two sets of parallel detachable clamping seats installed between the two sets of fixed end seats. A clamping hydraulic cylinder for controlling the detachable clamping seats is installed in the middle of the two sets of fixed end seats.
[0006] Two sets of guide rods are inserted into both ends of the fixed end seat, and a threaded connector is provided coaxially at one end of the guide rod that is connected to the detachable clamp.
[0007] The detachable clamp has a first connecting seat at both ends of its back side that is adapted to the size of the threaded connector and is threadedly connected. The detachable clamp has a second connecting seat at the center of its back side that is inserted into the piston rod end of the clamping hydraulic cylinder. The second connecting seat has a locking bolt installed on its outer circumferential wall.
[0008] Preferably, the end of the guide rod away from the threaded connector is coaxially connected to a limiting seat.

[0028] Quick-release milling machine fixtures, such as Figures 1-3As shown, the machine includes a milling table 10. Fixed end seats 20 are symmetrically arranged at both ends of the top surface of the milling table 10. Two sets of parallel detachable clamping seats 30 are installed between the two sets of fixed end seats 20. A clamping hydraulic cylinder 40 for controlling the detachable clamping seats 30 is installed in the middle of the two sets of fixed end seats 20. Two sets of guide rods 21 are inserted into both ends of the fixed end seats 20. A threaded connector 23 is coaxially provided at one end of the guide rod 21 that connects to the detachable clamping seat 30. First connecting seats 31, which are threaded and matched to the size of the threaded connector 23, are installed at both ends of the back of the detachable clamping seat 30. A second connecting seat 32, which is inserted into and mates with the end of the piston rod 41 of the clamping hydraulic cylinder 40, is installed at the center of the back of the detachable clamping seat 30. A clamping hydraulic cylinder 40 is installed on the outer circumferential wall of the second connecting seat 32. Equipped with locking bolts 33, a clamping hydraulic cylinder 40 is located in the middle of two sets of fixed end seats 20 to control the clamping and loosening of the detachable clamp 30, improving clamping efficiency. A guide rod 21 is inserted into both ends of the fixed end seats 20, and one end of the guide rod is coaxially provided with a threaded connector 23 that is threadedly connected to the first connecting seat 31 on the back of the detachable clamp 30, ensuring the stability and accuracy of the detachable clamp 30 during movement. A second connecting seat 32 on the back of the detachable clamp 30 is inserted into the end of the piston rod 41 of the clamping hydraulic cylinder 40, and a locking bolt 33 is installed on the outer circumference of the second connecting seat 32, realizing the quick installation and removal of the detachable clamp 30, thereby improving the flexibility and applicability of the clamp.
[0029] Furthermore, the end of the guide rod 21 away from the threaded connector 23 is coaxially connected to the limiting seat 22, which effectively prevents the guide rod 21 from being over-inserted or falling out when it is inserted into the fixed end seat 20, thereby enhancing the stability and service life of the guide rod 21.
[0030] Specifically, the surface of the detachable clamp 30 that contacts the workpiece is provided with an anti-slip pad 34. The surface of the anti-slip pad 34 is provided with several sets of uniformly spaced anti-slip protrusions 35, which makes it difficult for the workpiece to slide or shift during the clamping process, thereby improving the processing accuracy and stability.
[0031] The anti-slip pad 34 and the detachable clamp 30 are connected by several sets of plug-in pins 36 through an interference fit, which allows the anti-slip pad 34 to be firmly installed on the detachable clamp 30, while facilitating replacement and maintenance, and improving the flexibility and durability of the clamp.
[0032] In addition, the piston rod 41 of the clamping hydraulic cylinder 40 is coaxially mounted with a plug 42 that is compatible with the size of the second connecting seat 32 and is plugged in. The outer wall of the plug 42 is provided with a locking screw hole 43 that is compatible with the size of the locking bolt 33 and is threaded in, so that the clamping hydraulic cylinder 40 can be more stably connected to the detachable clamping seat 30 and a firm locking effect can be achieved through the locking bolt 33, thereby improving the clamping force and safety of the clamp.
[0033] The working principle of this quick-detachable milling machine fixture:
[0034] First, place the workpiece in a suitable position on the milling machine table 10; then, control the movement of the detachable clamping seat 30 by clamping hydraulic cylinder 40. The plug 42 at the end of the piston rod 41 of clamping hydraulic cylinder 40 is inserted into the second connecting seat 32 at the center of the back of the detachable clamping seat 30, and the locking bolt 33 is screwed into the locking screw hole 43 on the outer wall of the plug 42 for fastening, thereby realizing the connection between clamping hydraulic cylinder 40 and detachable clamping seat 30.
[0035] Next, the clamping hydraulic cylinder 40 is activated, the piston rod 41 extends, and pushes the detachable clamp 30 to move along the guide rod 21. The guide rods 21 at both ends of the fixed end seat 20 are threadedly connected to the first connecting seats 31 at both ends of the back of the detachable clamp 30 through the threaded connector 23, which plays a guiding role, so that the detachable clamp 30 smoothly approaches the workpiece until the detachable clamp 30 contacts the workpiece. The anti-slip pad 34 and anti-slip protrusion 35 on one side of its surface increase the friction and firmly clamp the workpiece.
[0036] After processing, the hydraulic cylinder 40 is reversed, the piston rod 41 retracts, and the detachable clamp 30 is moved away from the workpiece, releasing the clamp on the workpiece; then the locking bolt 33 is unscrewed, so that the plug 42 is separated from the second connecting seat 32. Finally, the detachable clamp 30 can be quickly disassembled through the threaded connection between the first connecting seat 31 and the threaded connector 23, which is convenient for subsequent maintenance or replacement; the limit seat 22 restricts the movement range of the detachable clamp 30 throughout the process to ensure its stable operation.
[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
