Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of automobile parts processing, in particular to a drilling device for machining automobile engine bed. BACKGROUND

[0002] The automobile engine bed, commonly known as "engine foot" or "engine foot rubber", is a component that connects and fixes the engine, gearbox and vehicle frame (sub-frame). The engine bed needs to firmly support them on the frame to prevent them from shifting or falling off due to gravity or vehicle movement.

[0003] During the machining of the engine bed, multiple mounting holes need to be drilled on the bottom and sidewall of the engine bed to facilitate its installation and fixation on the frame.

[0004] The existing engine bed drilling device has the following shortcomings:

[0005] 1. It cannot drill multiple mounting holes on the sidewall of the engine bed at the same time, and the mounting holes on the sidewall of the engine bed need to be processed one by one, which needs to be improved in terms of processing efficiency.

[0006] 2. The existing drilling device does not have a guide function for the drill bit. If the surface of the newly machined engine bed is not flat, it may cause the drilling position to deviate from the predetermined position, reducing the drilling accuracy of the engine bed.

The abutting plate 26 is fixedly arranged between the two sliding strips 27. The device is provided with a controller, and each electrical equipment on the device is electrically connected with the controller. When the automobile engine seat is processed and drilled, first, the seat is manually gripped and located between the two abutting plates 26, and then the double-shaft air cylinder 22 is started by the controller, so that the output end of the double-shaft air cylinder 22 drives the first push plate 23 to stretch out to the end close to the seat. Since the abutting plate 26 is arranged on the first push plate 23, the abutting plate 26 is driven to stretch out to the end close to the seat, until the bottom end of the seat is tightly attached to the top of the abutting plate 26, and the other abutting plate 26 is matched to achieve clamping of the bottom of the seat.

[0058] The working principle of the present application: the device is equipped with a controller, and each electrical equipment on the device is electrically connected with the controller, when the automobile engine base machining drilling work is carried out, first, the machine base is manually gripped to be located between the two abutting plates 26, then the controller is started to drive the double-shaft air cylinder 22, so that the output end of the double-shaft air cylinder 22 drives the first push plate 23 to extend towards the end close to the machine base, since the abutting plate 26 is designed on the first push plate 23, the abutting plate 26 is driven to extend towards the end close to the machine base, until the bottom end of the machine base is tightly attached to the top of the abutting plate 26, and the other abutting plate 26 is matched to realize the clamping of the bottom of the machine base.

[0059] When the bottom of the machine base is clamped, the single-shaft air cylinder 28 is started through the controller, so that the output end of the single-shaft air cylinder 28 drives the second push plate 29 to vertically extend downwards, since the two ends of the second push plate 29 are respectively fixedly connected with the two third sliding blocks 31, each third sliding block 31 is in sliding connection with a second guide rail, and each pressing plate 30 is fixedly connected with a third sliding block 31, thereby driving the two pressing plates 30 to vertically descend, until the two pressing plates 30 are tightly attached to the top of the machine base, thereby realizing the clamping of the top of the machine base, it should be noted that since each pressing plate 30 and each abutting plate 26 are L-shaped plate structures, the machine base is locked in the longitudinal and transverse directions, so that the machine base does not shift or shake during drilling, and the drilling effect is improved.

[0060] When the base is completely fixed, the first electric push rod 32 is started through the controller, so that the output end drives the first push block 33 to slide on the top of the first slide rail 34 to the end close to the base. Since the first slide plate 10 is fixedly connected with the first push block 33, and the first drill sleeve 19 is fixedly connected with the first slide plate 10, when the first drill sleeve 19 slides to the position above the corresponding drilling hole at the bottom of the base, the output end of the first electric push rod 32 is stopped.

[0061] When the first drill sleeve 19 slides to the position above the corresponding drilling hole at the bottom of the base, the third electric push rod 39 is started through the controller. Since the lifting plate 40 is slidingly connected with the third slide rail, the output end drives the lifting plate 40 to vertically descend through the connecting plate 42. Since the DC motor 41 is inserted with the lifting plate 40, the first drill bit 14 is fixedly connected with the output end of the DC motor 41 through the mounting disc, the first drill bit 14 is consistent with the axis direction of the first drill sleeve 19, and then the first drill bit 14 passes through the first drill sleeve 19 to drill the bottom of the base. Under the guidance of the first drill sleeve 19, the first drill bit 14 is limited in the drilling area, and is not easy to slip away from the predetermined punching position due to the uneven surface of the base, thereby improving the drilling accuracy of the base.

[0062] While the first drill bit 14 slides upward from the bottom of the base, the drive motor 15 is started through the controller. Since each synchronous wheel 44 is fixedly connected with a rotating shaft 18, the two synchronous wheels 44 are sleeved with the synchronous belt 43, each drive motor 15 is inserted with a first sliding block 17, and two second drill bits 16 are fixedly connected with the output ends of the two drive motors 15 through the two rotating shafts 18. U-shaped plates are fixedly designed between every two longitudinally arranged first sliding blocks 17, each rotating shaft 18 is rotatably connected with the U-shaped plate, and the other two second drill bits 16 are rotatably connected with the two first sliding blocks 17 at the bottom through bearings. Then the two second drill bits 16 are driven to rotate synchronously, and cooperate with another synchronous assembly to make the four second drill bits 16 rotate synchronously.

[0063] When the four first drill bits 14 rotate synchronously, the second electric push rod 35 is started through the controller, so that the output end drives the second push block 36 to push to the end close to the support plate 12. Since each fourth sliding block 38 is slidingly connected with a second slide rail 37, the bottom of the second slide plate 11 is fixedly connected with the top of the two fourth sliding blocks 38, the second push block 36 is fixedly connected with the bottom of the second slide plate 11, and the output end of the second electric push rod 35 is fixedly connected with the second push block 36. Thus the second slide plate 11 is driven to slide to the end close to the support plate 12. Since each second drill bit 16 is consistent with the axis direction of a second drill sleeve 20, the four second drill bits 16 are driven to slide through the four second drill sleeves 20 to the end close to the side wall of the base, until four mounting holes are drilled synchronously on the side wall of the base.

[0064] When the size of the machine base increases, the lateral spacing of the four mounting holes on the side wall of the machine base also increases. At this time, the servo motor 45 is started by the controller, so that the output end drives the rotating disc 46 to rotate. Each connecting rod 47 is hingedly designed at the eccentric position of the outer wall of the rotating disc 46. One end of each connecting block 48 is hingedly connected with the end of one connecting rod 47 away from the rotating disc 46, so as to drive the connecting rod 47 to rotate.

[0065] When the connecting rod 47 rotates, since each first sliding rod 52 is in sliding connection with one first sliding groove, one end of each first sliding rod 52 is fixedly connected with one first sliding block 17, the ends of the two first sliding rods 52 away from the first sliding block 17 are fixedly connected with the two ends of the first connecting column 50 respectively, the end of the connecting block 48 away from the connecting rod 47 is fixedly connected with the first connecting column 50, each second sliding rod 53 is in sliding connection with one second sliding groove, one end of each second sliding rod 53 is fixedly connected with one second sliding block 21, the ends of the two second sliding rods 53 away from the second sliding block 21 are fixedly connected with the two ends of the second connecting column 51 respectively, the guide rod 49 is fixedly connected with the first connecting column 50, and the end of the guide rod 49 away from the first connecting column 50 is in sliding connection with the second connecting column 51, thereby driving the four first sliding blocks 17 and the four second sliding blocks 21 to move away from each other, i.e. driving the four second drill bits 16 and the four second drill sleeves 20 to move away from each other, so as to facilitate synchronous drilling of four mounting holes in the side wall of a larger size machine base.

[0066] When the size of the machine base increases, the position of the mounting hole at the bottom of the machine base also changes. The output end of the first electric push rod 32 drives the first push block 33 to slide horizontally on the top of the first sliding rail 34, thereby driving the first sliding plate 10 to slide horizontally through the first push block 33, so that the first indicating rod 54 slides horizontally beside the first scale value 55, facilitating workers to observe the distance change between the mounting hole at the bottom of a larger size machine base and the drilling point of the bottom of a smaller size machine base. Similarly, the sliding distance of the second indicating rod 56 on the second sliding block 21 can facilitate workers to observe the distance change between the four mounting holes on the side wall of a larger size machine base and the four mounting holes on the side wall of a smaller size machine base, so as to quickly adjust the sliding distance of the first drill bit 14 and the four second drill bits 16 next time when encountering drilling requirements of machine bases of different sizes, thereby improving the drilling efficiency and accuracy of the machine base, and at the same time meeting the drilling requirements of machine bases of different sizes, further improving the practicality and flexibility of the device.
