[0022] Please see Figures 1 to 4 This utility model provides a machine tool with an adjustable feed angle for cutting or punching long strip-shaped workpieces. The machine tool includes a base plate 10, two support plates 20 mounted on the base plate 10, a main frame 30, a rotating shaft 60 passing through both the main frame 30 and the support plates 20, a fixed shaft 70 passing through the main frame 30 and located behind the rotating shaft 60, two limiting devices 50 mounted on the base plate 10 and located on both sides of the two support plates 20, and a processing assembly 40 mounted on the main frame 30. The main frame 30 can rotate around the axis of the rotating shaft 60 to adjust the angle. After the adjustment is completed, the limiting device 50 limits the fixed shaft 70, thereby indirectly fixing the angle of the main frame 30.
[0023] The support plate 20 has a first through hole 21 at the front side and an adjustment hole 22 at the rear side. The adjustment hole 22 is an arc-shaped hole. The two support plates 20 are arranged opposite to each other. The first through hole 21 and the adjustment hole 22 on the support plate 20 are respectively opposite to the first through hole 21 and the adjustment hole 22 on the other support plate 20.
[0024] The main frame 30 includes two main plates 31 arranged opposite each other, a guide rail 34 mounted on the two main plates 31, a horizontal plate 32 connecting the upper ends of the two main plates 31, and a machining seat 33 mounted on the two main plates 31. A recess 311 is provided on the front side of each main plate 31 near its bottom, and the machining seat 33 is simultaneously mounted at the bottom of the recess 311 on both main plates 31. The machining seat 33 has a machining groove 331 extending horizontally, and also has a machining hole 332 extending from the upper end face of the machining seat 33 into the machining groove 331.
[0025] The main body plate 31 has a second through hole 311 at the bottom front side and a positioning hole 312 at the bottom rear side. The second through holes 311 on the two support plates 20 are arranged opposite to each other, and the positioning holes 312 on the two support plates 20 are also arranged opposite to each other.
[0026] During assembly, the rotating shaft 60 passes through the first through hole 21 of the support plate 20 and the second through hole 311 of the main body plate 31, so that the main body frame 30 can rotate around the axis of the rotating shaft 60. The fixed shaft 70 passes through the adjustment hole 22 on the support plate 20 and the positioning hole 312 of the main body plate 31. The fixed shaft 70 can be rotated and adjusted in the arc direction within the adjustment hole 22 to adjust the angle of the main body frame 30.
[0027] The processing assembly 40 includes a drive cylinder 41, a connecting seat 42 connected to the drive cylinder 41, a cutting head 43 installed at the bottom of the connecting seat 42, and guide bars 44 installed on both sides of the connecting seat 42. The guide bars 44 pass through the guide rail 34 in a vertical direction, and the guide rail 34 guides the guide bars 44 and the connecting seat 42 in a vertical direction. The drive cylinder 41 is installed on the horizontal plate 32. The drive cylinder 41 drives the connecting seat 42 and the cutting head 43 installed on the connecting seat 42 to adjust in a vertical direction, so that the cutting head 43 extends from the processing hole 332 of the processing seat 33 into the processing groove 331 to process the workpiece, or withdraws from the processing hole 332.
[0028] Each of the aforementioned limiting devices 50 includes a guide seat 51, a positioning seat 52 slidably mounted on the guide seat 51, a locking seat 53 located behind the positioning seat 52, a bearing 57 mounted on the locking seat 53, an adjusting rod 54 mounted on the bearing 57 and the positioning seat 52, a handle 55 mounted on the tail end of the adjusting rod 54, and a locking pin 56 mounted on the locking seat 53 and limiting the adjusting rod 54 in the front and rear directions. The adjusting rod 54 is installed in conjunction with the positioning seat 52 by means of a thread. When the adjusting rod 54 is rotated by the handle 55, the adjusting rod 54 drives the positioning seat 52 to move forward or backward. During the backward movement of the positioning seat 52, the fixed shaft 70 is locked on the positioning seat 52.
[0029] Specifically, the guide seat 51 and the locking seat 53 are fixedly installed on the base plate 10. The guide seat 51 is provided with a guide part 511, and the cross-section of the guide part 511 is T-shaped. The bottom of the positioning seat 52 is provided with a sliding groove 522, and the groove shape of the sliding groove 522 corresponds to the guide part 511. During assembly, the guide part 511 of the guide seat 51 is inserted into the sliding groove 522 of the positioning seat 52 in the horizontal direction.
[0030] The positioning seat 52 has several bayonet slots 523 on its rear side, which extend forward from the rear side of the positioning seat 52, and the bayonet slots 523 are at different heights. The positioning seat 52 also has a mating hole 521, which penetrates the positioning seat 52 in the front-to-back direction, and the positioning seat 52 has an internal thread on the wall of the mating hole 521. The adjusting rod 54 has an external thread, which engages with the internal thread of the mating hole 521 for installation.
[0031] Additionally, a functional protrusion 531 is provided on the side of the locking seat 53 facing away from the guide seat 51. The functional protrusion 531 has a fixing hole, the extension direction of which is perpendicular to the installation direction of the adjusting rod 54. The outer peripheral surface of the adjusting rod 54 also has a retaining groove 541, which is distributed around the axis of the adjusting rod 54. During assembly, the retaining pin 56 is installed on the fixing hole by threads or other means, with one end of the retaining pin 56 extending into the retaining groove 541, thereby limiting the adjusting rod 54 in the front-back direction.
[0032] The two limiting devices 50 respectively fix and limit the two ends of the fixed shaft 70. The fixed shaft 70 is inserted into one of the slots 523 of the positioning seat 52. When it is necessary to adjust the angle of the main frame 30 and the processing component 40 installed on the main frame 30, the adjusting rod 54 is rotated. Since the adjusting rod 54 is limited in the front-back direction by the locking pin 56, the adjusting rod 54 pushes the positioning seat 52 forward through the threaded engagement, so that the slot 523 of the positioning seat 52 is disengaged from the fixed shaft 70. The position of the fixed shaft 70 is adjusted according to the required adjustment angle and the height of the slot 523. Then the adjusting rod 54 is rotated in the opposite direction. During the process of the positioning seat 52 moving backward, the fixed shaft 70 is locked in the slot 523 on the positioning seat 52. In this embodiment, there are three slots 523, and the positioning seat 52 can fix the fixed shaft 70 at three height positions.
[0033] The beneficial effects of this adjustable-feed-angle machine tool are as follows: By setting a rotating shaft 60, a fixed shaft 70, and a limiting device 50, the rotating shaft 60 passes through both the main frame 30 and the support plate 20. The main frame 30 can rotate around the axis of the rotating shaft 60 to adjust its angle. The fixed shaft 70 passes through the main frame 30 and is located behind the rotating shaft 60. After adjustment, the limiting device 50 limits the fixed shaft 70, thereby indirectly fixing the angle of the main frame 30. This invention allows for angle adjustment and fixation of the main frame 30 and the processing assembly 40. Its overall structure is flexible, and when used with feeding equipment, it reduces the requirements for the feeding equipment, making it highly practical.
[0034] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0035] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
