[0029] The beneficial effect of the utility model

[0030] Firstly, the head and tail of the part are positioned and supported by the first pressing part and the second pressing part respectively, and then the bottom of the part is supported by the rotating positioning device, so that the part is supported from three directions, which not only achieves the effect of stable support, but also the drilling, milling and tapping processes can be carried out on the top of the part, and the support of the first pressing part, the second pressing part and the rotating positioning device will not affect the processing of the part.

It should be understood that if the positioning holes are arranged more densely, although the rotating positioning device can support in more positions to a certain extent, a problem will occur, that is, with excessive increase of the positioning holes, the effective bearing area of the base plate will be reduced. In addition, a stress concentration area is easily formed at the edge of the positioning hole, especially under uneven load, especially when drilling, milling, tapping and other processing are performed, the load of different processing modes is uneven. Such stress concentration can cause fatigue of the material around the positioning hole, and further cause cracks or other forms of damage.

In addition, when the part to be processed is large and needs to be supported by multiple rotating positioning devices, the rotation angle of each rotating positioning device can be controlled to ensure that more rotating positioning devices can be accommodated on the base plate. Because the space structure of the base plate is fixed, when there are many rotating positioning devices, it is easy to collide with each other, which can only reduce the number of rotating positioning devices. The rotation angle of each rotating positioning device of the present scheme can be controlled, so that more rotating positioning devices can be accommodated to avoid collision of the rotating positioning devices. The rotation function reaches the maximum space utilization of the base plate.

[0033] Then, a pushing device is provided for driving the second pressing member to make reciprocating motion towards the first pressing member, so as to be suitable for supporting different head-tail sizes of parts, that is, suitable for assembly of multiple parts. BRIEF DESCRIPTION OF DRAWINGS

[0046] As shown in FIGS. Figure 3 , 4 and 5, a multi-part, multi-station drilling, milling, and tapping tool includes a first fixed main block 1 and further includes a rotary positioning device 4, the rotary positioning device 4 including at least four first rotary positioning units 41 and four second rotary positioning units 42. The first rotary positioning unit 41 includes a first base plate 411, a first positioning pin 413, and a first locking piece 412. As shown in FIG. Figure 4 , the left end of the first base plate 411 is fixedly installed with the first positioning pin 413, and the right end of the first base plate 411 is provided with a first sliding groove 414; the first sliding groove 414 is in sliding connection with the first locking piece 412, and the first locking piece 412 is in detachable connection with the positioning hole 121. The first locking piece 412 includes a first locking screw 4122 and a first washer 4121; the first washer 4121 abuts against the first base plate 411, and the first locking screw 4122 passes through the first washer 4121 and the first sliding groove 414; the first locking screw 4122 is in matching connection with the positioning hole 121. Specifically, the length of the first sliding groove 414 is a, a = 89 mm. The length of the first base plate is b, b = 150 mm. The width of the first base plate is c, c = 30 mm. In this embodiment, the first positioning pin 413 can be an adjustable positioning pin, which is a prior art. According to the prior art, the adjustable positioning pin includes a hexagonal flat head screw 4123 and an M10 nut 4124, and a threaded hole for connecting the hexagonal flat head screw 4123 is formed at the left end of the first base plate, and the first base plate is in threaded connection with the hexagonal flat head screw 4123. The M10 nut 4124 is nested outside the threaded rod of the hexagonal flat head screw 4123, and the M10 nut 4124 is in threaded connection with the hexagonal flat head screw 4123. The height of the adjustable positioning pin is adjusted by the length of the thread of the hexagonal flat head screw 4123 that is screwed into engagement, and the height of the hexagonal flat head screw 4123 is locked by the M10 nut 4124. In this embodiment, the distance between the top of the adjustable positioning pin and the bottom of the first base plate is d, 43.5 mm ≤ d ≤ 78.5 mm. In other embodiments, the first positioning pin 413 can be a positioning pin with a fixed height.

[0047] The second rotating positioning unit 42 comprises a second base plate, a second positioning pin and a second locking piece 422. One end of the second base plate is fixedly provided with the second positioning pin, and the other end of the second base plate is provided with a second sliding groove. The second sliding groove is slidably connected with the second locking piece 422, and the second locking piece 422 is detachably connected with the positioning hole 121. The second locking piece 422 comprises a second locking screw and a second gasket. The second gasket abuts against the second base plate, the second locking screw passes through the second gasket and the second sliding groove, and the second locking screw is matched with the positioning hole 121. In the embodiment, the second base plate, the second positioning pin and the second locking piece 422 of the second rotating unit are respectively the same in structure and size as the first base plate 411, the first positioning pin 413 and the first locking piece 412 of the first rotating positioning unit 41. The difference between the second rotating positioning unit 42 and the first rotating positioning unit 41 is that the first pressing screw 421 is arranged on the second positioning pin and close to the second sliding groove. Specifically, a threaded hole is arranged on the second positioning pin for threadedly connecting the first pressing screw 421. The first pressing screw 421 is threadedly connected with the second positioning pin, and the first pressing screw 421 is used for locking the second positioning pin. Specifically, when the first pressing screw 421 is loosened, the second positioning pin is an adjusting pin, which can rotate in a horizontal plane. When the first pressing screw 421 is tightened, the second positioning pin cannot rotate, which is equivalent to increasing the supporting force of the bottom of the part. The second positioning pin cannot rotate in the horizontal plane due to the force transmitted from the machined part 6 to the second positioning pin during the machining process. The second positioning pin is locked by the first pressing screw 421, and the first pressing screw 421 locking the second positioning pin is the prior art.

[0048] Use mode of the embodiment

[0049] As shown in Figure 2 and 3 , according to the length of the machined part 6, the heads of a plurality of machined parts 6 are inserted into the tapered pins, and then the machined parts 6 are parallel to the bottom plate 12. The pressing head is pushed by the cylinder 5 to abut against the tail of the machined part 6. Then the first rotating positioning unit 41 or the second rotating positioning unit 42 is used to position and support the bottom of the machined part 6.

[0050] Specifically, in the embodiment, for one machined part 6, one first rotating positioning unit 41 and one second rotating positioning unit 42 are used to position and support the bottom of the machined part 6. The first rotating positioning unit 41 is first installed on the positioning holes 121 of the first row as shown in Figure 2 , and then one side of the machined part 6 is supported. Then the second rotating positioning unit 42 is installed on the positioning holes 121 of the second row as shown in Figure 2The second positioning pin can be adjusted in horizontal position by moving the second locking member 422 on the second sliding groove on the positioning hole 121. When the second locking member 422 is not locked on the positioning hole 121, the angle of the second base plate can be adjusted, and then locked on the positioning hole 121 by the second locking member 422. In this way, the second positioning pin can accurately position and support the workpiece 6. Moreover, the height of the first positioning pin 413 and the second positioning pin can be adjusted to the height that can abut against the workpiece 6. In this way, the workpiece 6 can be positioned and supported from the head, tail and bottom of the workpiece 6. So that the drilling, milling or tapping processing can be carried out above the workpiece 6. The drilling, milling or tapping device processes the top of the workpiece 6 from top to bottom, as shown in Figure 3 Figure 3 The top view of the assembled workpiece 6 can also be processed from the front direction of the workpiece 6. Figure 3

[0051] In other embodiments, the workpiece 6 can not be the same, so the positioning hole 121 and the rotating positioning device 4 have rotating characteristics, which can enable different rotating positioning devices 4 to stably, accurately, independently and separately support the corresponding positions of the bottom of different workpieces 6 without interfering or colliding with each other in multi-station drilling, milling or tapping processing.

[0052] Advantages of the embodiment

[0053] Compared with the prior art, such as the patent application No. CN201620041703.3, the structure of the embodiment is completely different. The embodiment uses several rotating positioning devices 4 to accurately support the workpiece 6. The operator locks the workpiece 6 by the rotating positioning device 4, which can ensure that the workpiece 6 can be locked, that is, the workpiece 6 can be stably processed, and the quality of the processed workpiece is ensured. Moreover, if the rotating positioning device 4 is damaged, it can be replaced in time. The rotating positioning device 4 can have a replacement, which does not need to be repaired, and the production efficiency will not be reduced by directly replacing it. At the same time, the components of the rotating positioning device 4 are some low-cost and easy-to-install components, which are easy to manufacture and have low cost. In the case of damage, it can be replaced in time without affecting the production efficiency.

[0054] Moreover, through the design of the positioning hole 121, multiple workpieces 6 can be clamped and assembled in a multi-workpiece and multi-station drilling, milling or tapping tool, achieving the effect of multi-station processing.

[0055] Embodiment two

[0056] ​​Different from the first embodiment, in the present embodiment, as shown in Figure 6 and 7 The pushing device is connected with the second pressing member 3, and the pushing device is used for driving the second pressing member 3 to reciprocate towards the first pressing member 2.

[0057] Specifically, in the present embodiment, the pushing device is a cylinder 5, and there are four cylinders 5. The cylinder 5 comprises a first push rod 51 and a cylinder body, and the first push rod 51 is a cylindrical body structure. Four connecting through holes 131 are formed on the second vertical plate 13, and each push rod passes through an independent connecting through hole 131.

[0058] One end of the four first push rods 51 is located in the cylinder body, and the other end of the four first push rods 51 respectively passes through the connecting through hole 131, and the other end of the four first push rods 51 is fixedly connected with the four second pressing members 3 respectively. The second pressing member 3 is a pressing head, and in the present embodiment, the pressing head is a circular boss structure. The surface area of the pressing head is larger than the hole diameter of the connecting through hole 131, so that the pressing head cannot pass through the connecting through hole 131. As shown in Figure 7 The cylinder 5 drives the pressing head to move horizontally in the up-down direction through the push rod, and the pressing head can horizontally approach / away from the first pressing member 2. The distance between the bottom of the pressing head and the connecting through hole 131 is g, and g=0-100mm.

[0059] The beneficial effects of the present embodiment

[0060] The second pressing member 3 is pushed by the cylinder 5 to press the part to be machined 6, and the distance between the bottom of the pressing head and the connecting through hole 131 is adjustable, between 0-100mm, which can meet the requirements of most models of the part to be machined 6. If it exceeds 100mm, when the cylinder 5 pushes the second pressing member 3 to press the part to be machined 6, the part to be machined 6 will be subjected to the force of the drilling, milling and tapping tools during the machining process, which will cause the second pressing member 3 of the machined part to shake, thereby reducing the machining quality. Therefore, when the cylinder 5 with low cost is selected, the pressing force should be considered to avoid the shaking of the second pressing member 3, so as to reduce the quality of the machined part.
