[0036] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around", etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0037] Example

[0038] refer to Figures 1-5 As shown, a gearbox end cover drilling device includes:

[0039] The machine base 10 has at least five product carriers 20 mounted on top of it along the processing direction for placing the reducer end cover; a first linear drive module 30 is mounted on the bottom of the at least five product carriers along the processing direction above the machine base, and at least three lifting drive components a40 are connected to the first linear drive module. The at least three lifting drive components a40 are connected to lifting rods 50 on both sides of the at least five product carriers along the processing direction for lifting the reducer end cover.

[0040] In addition, a frame 230 is set above the machine tool along the processing direction. At least five product carriers are arranged on the table surface of the frame along the processing direction. Several pins 21 are arranged in a circular array on the product carriers for insertion into the slots of the reducer end caps. Multiple support members are connected between the table surface of the frame and the machine tool along the processing direction. In actual use, the operator needs to mate the slots of the reducer end caps to be processed with the pins. The multiple support members connected between the table surface of the frame and the machine tool can effectively support the table surface of the frame, thereby preventing the table surface of the frame from being crushed by multiple reducer end caps.

[0041] Three product pressure plates 60 are arranged sequentially above at least five product carriers along the processing direction. Three lifting drive components b70 are provided at the bottom of the machine and are respectively connected to the three product pressure plates.

[0042] One side of each of the three product pressure plates is provided with an oil reservoir 80 for the subsequent bottom hole machining tools, tapping and drilling tools and countersunk machining tools to be dipped in oil;

[0043] The machine tool is provided with a second linear drive module 90 on both sides of the first linear drive module along the processing direction. The second linear drive module is connected in sequence along the processing direction with truss a100, truss b110 and truss c120.

[0044] A third linear drive module 130 is provided on one side of the crossbeam of truss a along its length. A lifting and rotating drive assembly a140 is connected to the third linear drive module. A bottom hole machining tool 150 is installed on the rotating output end of the lifting and rotating drive assembly a.

[0045] A fourth linear drive module 160 is provided on one side of the crossbeam of truss b along its length direction. A lifting and rotating drive assembly b170 is connected to the fourth linear drive module. A tapping tool 180 is installed on the rotating output end of the lifting and rotating drive assembly b.

[0046] A fifth linear drive module 190 is provided on one side of the crossbeam of truss c along its length direction. A lifting and rotating drive assembly c200 is connected to the fifth linear drive module. A countersunk machining tool 210 is installed on the rotating output end of the lifting and rotating drive assembly c.

[0047] The unloading production line 250 is set on the machine platform corresponding to one side of the second linear drive module along the processing direction;

[0048] Product handling assembly 220 is mounted at the end of the processing direction above at least five product carriers and unloading assembly lines to handle processed products to the unloading assembly line.

[0049] In one specific embodiment, the first linear drive module is a screw slide module a with three slides. The lifting drive assembly a includes two linear cylinders a41. The two linear cylinders a are respectively located on both sides of one slide of the screw slide module a and their piston rods are connected to lifting rods. Driven by the screw slide module a and the six linear cylinders a, the reducer end cover placed between the two lifting rods can be lifted and transported to the next station. After the two lifting rods transport the reducer end cover to the next station, the six linear cylinders will drive the two lifting rods to reset. The screw slide module a will drive the six linear cylinders to reset. It can be understood that the two lifting rods lift all the reducer end covers to the next station each time.

[0050] In one specific embodiment, three sets of connecting plates 240 are respectively installed on the machine bases on both sides of the first linear drive module. Each connecting plate has two guide sleeves 241 inside. Four guide posts 64 are installed around the bottom of the product pressure plate, passing through the four guide sleeves on the two opposite connecting plates. An X-shaped base plate 65 is connected to the bottom of the four guide posts on the product pressure plate. The lifting drive assembly b includes a linear cylinder b71 and a fixed plate 72. The fixed plate is fixed to the two opposite connecting plates by support columns. The linear cylinder b is located at the bottom of the fixed plate. The piston of the linear cylinder b... The rod connects to the X-shaped base plate, which, driven by the linear cylinder b, will achieve lifting and lowering. Since the four guide pillars connected to the product pressure plate are fixed on the X-shaped base plate, the product pressure plate can also be lifted and lowered. In addition, since the middle part of the reducer end cover is an upward protrusion, the middle part of the product pressure plate of the present invention is provided with a clearance groove a61 for the protrusion of the reducer end cover to pass through. Moreover, in order to facilitate the processing of the corresponding position of the reducer end cover, the present invention also provides a number of clearance grooves b62 for processing clearance in a circular array around the clearance groove a.

[0051] In one preferred embodiment, in the processing direction, a guide block 63 is provided above the clearance groove b on the first product pressure plate. A row of guide holes 631 communicating with the clearance groove b are provided on the guide block. The row of guide holes on each guide block is of different sizes. During the processing, the bottom hole processing tool will process the bottom hole of the reducer end cover along the guide holes. This can avoid errors in the opening position and effectively ensure the processing quality of the bottom hole. In addition, since the guide holes on the guide block are of different sizes, it is convenient to process the bottom hole of reducer end covers of different sizes.

[0052] Among them, the lifting and rotating drive components a, b and c are integrated lifting and rotating drive modules with the same structure. The specific structure of the lifting and rotating drive module is known technology and will not be described in detail here.

[0053] Among them, the two second linear drive modules are both lead screw slide modules b with three slides. Trusses a, b and c are installed on the three slides of the two lead screw slide modules b respectively. The third, fourth and fifth linear drive modules are all lead screw slide modules c with one slide. The first and second linear drive modules have the same structure and are readily available on the market. In addition, the third, fourth and fifth linear drive modules also have the same structure and are readily available on the market. The specific structure will not be described in detail here.

[0054] Alternatively, the unloading assembly line can be a chain-type assembly line. The structure of this chain-type assembly line is a known technology, and this invention will not elaborate on it here. In addition, the type of unloading assembly line can be selected according to the actual situation of those skilled in the art, as long as it can meet the unloading and conveying of the reducer end cover.

[0055] In one specific embodiment, the product handling assembly includes a truss d221, a rodless cylinder 222, and an inverted L-shaped plate 223. The rodless cylinder is located on one side of the crossbeam of the truss d. The inverted L-shaped plate is fixed to the slide of the rodless cylinder. A linear guide rail 229 is vertically arranged on the inner side of the inverted L-shaped plate, and a regular L-shaped plate 225 is connected to the linear guide rail. A linear cylinder c224 is located at the top of the inverted L-shaped plate, and the piston rod of the linear cylinder c passes through the inverted L-shaped plate and connects to the regular L-shaped plate. A rotary cylinder 228 is located at the bottom of the regular L-shaped plate, and a handling plate 226 is connected to the output end of the rotary cylinder. Four electromagnets 227 are located at the bottom of the handling plate. Since the middle part of the reducer end cover is a hollow protrusion, if a large electromagnet is used, the reducer end cover will contact the electromagnet. Iron has a small magnetic field area, so it cannot attract the reducer end cover. This invention uses four electromagnets to attract the reducer end cover. The hollow protrusion of the reducer end cover has a large magnetic field area, so it can be attracted by the four electromagnets. In actual use, the rodless cylinder moves the inverted L-shaped plate to above the last product carrier, the linear cylinder C drives the upright L-shaped plate to descend, and the rotary drive cylinder adjusts the direction of the four electromagnets. After reaching the position, the reducer end cover is attracted by the four electromagnets. After that, the linear cylinder C drives the upright L-shaped plate to reset, the rodless cylinder moves the inverted L-shaped plate to above the unloading line, and the linear cylinder C drives the upright L-shaped plate to descend. When the four electromagnets are de-energized, the reducer end cover will be placed on the unloading line.

[0056] In practice, the operator places the reducer end caps to be processed one by one on the product carrier corresponding to the starting end. With the cooperation of the linear drive module a and the three lifting drive components, the two lifting rods lift the reducer end caps forward in sequence. When the reducer end cap is under the first product pressure plate, the lifting drive component b drives the product pressure plate to press the reducer end cap. With the cooperation of the two second linear drive modules, the third linear drive module and the lifting and rotating drive components, the bottom hole machining tool can machine the bottom hole on the reducer end cap. Similarly, the tapping tool will tap the reducer end cap under the second product pressure plate (tapping is done in the bottom hole), and the countersunk tool will countersunk the reducer end cap under the third product pressure plate (countersunk is also done in the bottom hole). After the reducer end cap has completed the bottom hole machining, tapping, and countersunk machining and reaches the last station, the product handling component will transport the processed reducer end cap to the unloading line, and the unloading line will then unload the processed reducer end cap.
