[0031] As shown in the various drawings, the present application provides a feeding and alignment device for a multi-head tapping machine, which is used for feeding and aligning the workpieces processed by the multi-head tapping machine. For example, when processing a workpiece 7 as shown in Figure 8 shown, it is necessary to process the through holes 71 on both sides of the workpiece 7. The device includes a support base 2 with multiple pairs of tapping holes 26 arranged horizontally at the top, a first alignment plate 3 and a second alignment plate 4 arranged in sequence on the top of the support base 2, a push plate support plate 5 arranged on the front side of the support base 2, and a push plate 6 movably arranged on the top of the push plate support plate 5.

[0032] In this embodiment, as shown in Figure 1 and Figure 3 shown, the support base 2 is in a "J" shape, including bottom horizontal plates 21 on both sides, vertical plates 22 perpendicular to the bottom horizontal plates 21 on both sides respectively, and a top horizontal plate 23 between the vertical plates 22 on both sides. Each pair of tapping holes 26 is arranged horizontally on the top horizontal plate 23. In this embodiment, 3 pairs of tapping holes 26 are set for illustration. When manufacturing the support base 2, it is generally formed by bending a whole metal plate (such as a steel plate). Figure 3 The dotted line in is the bending position. The bottom horizontal plates 21 on both sides of the support base 2 are used to install the entire feeding and alignment device on the multi-head tapping machine, usually by bolt connection. To facilitate the adjustment of the position of the support base 2, multiple pairs of first adjustment long holes 24 are correspondingly arranged on the two bottom horizontal plates 21 respectively. Each first adjustment long hole 24 is provided with a first bolt 9 that matches it. After the position of the support base 2 is adjusted, the first adjustment long hole 24 can be tightened.

[0033] In this embodiment, as shown in Figure 1 and 3As shown in Figure 7, the first alignment plate 3 and the second alignment plate 4 are rectangular in shape with the same dimensions. Rectangular first alignment grooves 31 and third alignment grooves 42, with the same width, are respectively provided on their front sides, corresponding to each pair of tapping holes 26. The depth of the third alignment groove 42 is less than the depth of the first alignment groove 31. Each tapping hole 26 is located near the bottom of the corresponding first alignment groove 31. A rectangular second alignment groove 41, with a width smaller than the third alignment groove 42, is provided at the center of the bottom side of the third alignment groove 42. The width of the second alignment groove 41 matches the arc diameter of the center of the workpiece 7 to be machined. Corresponding to each pair of tapping holes 26, each second alignment groove 41 has corresponding grooves on both sides. The corresponding U-shaped grooves 43 are located at the corresponding positions of the corresponding pairs of U-shaped grooves 43. The first partition part 32 and the second partition part 44 are formed between adjacent first alignment grooves 31 and adjacent third alignment grooves 42, respectively. The top of the push plate support plate 5 is flush with the top of the support base 2, which facilitates the push plate 6 to be pushed forward or withdrawn. The push plate 6 includes a front top plate 61. The front side of the front top plate 61 is provided with a plurality of feeding alignment plates 611 that are adapted to each first alignment groove 31. The partition grooves 612 that are adapted to the first partition part 32 are between adjacent feeding alignment plates 611. When the push plate 6 moves forward or backward, each alignment plate 611 can be pushed into or withdrawn from the corresponding first alignment groove 31.

[0034] In this embodiment, to facilitate the detachable connection of the support base 2, the first alignment plate 3, and the second alignment plate 4, the top horizontal plate 23, the first alignment plate 3, and the second alignment plate 4 are respectively provided with multiple connecting holes 8 and are connected and fixed by the second bolts 10.

[0035] In this embodiment, as Figure 3 As shown, an elongated hole 25 is provided in the middle of each pair of tapping holes 26 on the top horizontal plate 23 to discharge the debris generated during workpiece processing, ensuring workpiece feeding alignment and normal processing.

[0036] In this embodiment, as Figure 6 As shown, the push plate support plate 5 includes a horizontal support plate 51 and a connecting vertical plate 52 that are perpendicular to each other. The top of the horizontal support plate 51 is flush with the top of the top horizontal plate 23. The connecting vertical plate 52 is provided with a plurality of third adjustment elongated holes 54. The vertical plate 22 on the front side of the support base 2 is provided with connecting holes 8 at positions corresponding to each third adjustment elongated hole 54. Each connecting hole 8 is connected and fixed to the corresponding third adjustment elongated hole 54 by a second bolt 10. Before fixing, the height position of the push plate support plate 5 can be adjusted by the position of the second bolt 10 in the third adjustment elongated hole 54.

[0037] In this embodiment, as Figure 6As shown, each horizontal support plate 51 is provided with at least two second adjusting elongated holes 53. A connecting hole 8 is provided on the rear side of the front top plate 61 of the push plate 6, corresponding to the position of each second adjusting elongated hole 53, and a third bolt 101 is provided thereon. The third bolt 101 is slidably connected to the second adjusting elongated hole 53, and the push plate 6 can be confined within the second adjusting elongated hole 53 by means of the third bolt 101. The horizontal support plate 51 is also made of bent steel plate. Figure 6 The dashed line in the middle indicates the bend position.

[0038] In this embodiment, as Figure 1 and Figure 7 As shown, to facilitate the forward and backward pushing of the push plate 6, a handle 62 is provided at the rear end of the front top plate 61. The push plate 6 is usually made of bent steel plate. Figure 7 The dashed line in the middle indicates the bend position.

[0039] In application, after setting the multi-head tapping machine with the feeding and positioning device, the... Figure 8 The workpiece 7 to be processed is placed in the first alignment slot 31 and the third alignment slot 42 of the first alignment plate 3 and the second alignment plate 4. Then, the push plate 6 is pushed so that the feeding alignment plates 611 of the front top plate 61 feed each workpiece 7 into the workpiece. When the workpiece 7 is fed to the second alignment slot 41, since the width of the second alignment slot 41 is smaller than the first alignment slot 31 and the third alignment slot 42, the arc-shaped position in the middle of the workpiece 7 is limited by the second alignment slot 41 and continues to be pushed inward. When it is pushed to the bottom of the first alignment slot 31, the through holes on both sides of the workpiece 7 are exactly in the position of the U-shaped slots 43 on both sides, and processing can be performed at this time.
